In industrial manufacturing, there are automated machines that specialize in controlling fluids and dribbling and coating them onto the surface or interior of products, including glue dispensing machines, coating machines, and dispensing machines. What is the difference between glue dispensing machines and dispensing machines

The glue dispenser, also known as the AB glue dispenser, is an automated machine that specifically controls the fluid and drips, coatings, and seals the liquid onto the surface or inside the product, achieving sealing, fixation, waterproofing, and other functions. Generally, two-component glue is used. The dispensing machine, also known as the glue coating machine, drip glue machine, glue dispensing machine, etc., is specifically designed to control the fluid. An automated machine that drips and coats the fluid onto the surface or interior of the product, achieving three-dimensional and four-dimensional path dispensing, precise positioning, precise glue control, no drawing, no leakage, and no dripping

The dispensing machine is mainly used for precise dispensing, injection, application, and dripping of glue, paint, and other liquids in the product process to the precise position of each product. It can be used to achieve dispensing, drawing lines, circular or arc shapes
The most straightforward difference between a glue dispenser and a dispensing machine is that glue dispensing is aimed at products with large amounts and areas of application, while dispensing is more focused on fine products with small areas

The glue dispenser is suitable for large areas and large quantities of glue. The cost of the glue dispenser is much higher than that of the dispensing machine. If the monthly usage is within a few hundred kilograms, it is generally not considered to use a glue dispenser, manual operation or dispensing machine 

The specific differences between glue dispensers and dispensing machines are as follows:

1. Different glue control methods: Currently, most dispensing machines on the market still rely mainly on air pressure to control the dispensing process. Of course, there are now some machines that do not require air pressure control, while dispensing machines mainly rely on a metering pump to control the dispensing process. The amount of dispensing is adjusted by adjusting the pump speed.At present, the main metering pumps on the market are: gear pumps (mainly used for unfilled glue), screw pumps (mainly used for filled glue, wear-resistant), plunger pumps (also known as ceramic pumps, super wear-resistant, but expensive). Therefore, when choosing a glue dispenser, everyone depends on their own products and the properties of the glue used to consider which pump is most suitable, Ruicheng Automation will recommend cost-effective equipment to customers based on their actual requirements <

2. Different sizes of dispensing volume: Relatively speaking, the minimum dispensing volume of the dispensing machine is larger than that of the dispensing machine, and the maximum dispensing volume of the dispensing machine can reach more than ten to twenty grams per second, while the dispensing machine has a smaller dispensing volume. Some dispensing machines can achieve a minimum dispensing volume of 0.001g.

3. Different dispensing accuracy: Relatively speaking, the dispensing accuracy of the dispensing machine is higher than that of the dispensing machine

4. Different applicable adhesives: Generally speaking, the dispensing machine is mainly suitable for two-component AB adhesives such as silicone, epoxy resin, crystal glue, polyurethane, and other two-component adhesives. And the glue dispenser is mainly suitable for single component glue, such as UV glue, EPOXY (black glue), white glue, EMI conductive glue, instant glue, silver glue, red glue, solder paste, heat dissipation paste, solder paste, transparent paint, screw fixing agent, etc. In recent years, due to technological progress, glue dispensers are no longer limited to only suitable for single component glue. Currently, there are also many glue dispensers that can be used for two-component glue.

In recent years, industrial automation has developed rapidly. Many companies use glue machines instead of manual labor. The use of glue dispensers can save labor and improve production efficiency. Besides, what other electrical and equipment features does the automatic glue dispenser have

Automated FCT testing equipment is mostly based on open hardware and software architecture design, which can flexibly expand hardware and quickly and conveniently establish testing programs; Generally, it can support multiple instruments and can be flexibly configured as needed; And it should have a rich range of basic testing projects to provide users with universal, flexible, and standardized solutions as much as possible

FCT testing is a customized functional testing system developed for the same series of PCBAs, which can simultaneously test the functions of different types of substrates in this series of products. Although products in the same series need to be updated and upgraded every year, their main functions are usually similar. We make functional testing (including testing software) universal, so that various substrates of the same series can be tested on this tester. When a new model of product is put into production testing, we only need to modify a few hardware configurations and software settings to conduct its functional testing. In this way, the development cycle and cost of FCT testing can be maximally saved

Compared with ordinary pressure switches, electronic pressure switches currently have the following characteristics:

With the development of the economy, distributors are widely used in industries such as electronics, lighting, automotive, industrial electrical, solar photovoltaic, and construction engineering. The most common problem with fully automatic glue dispensers is valve problems. The following are effective methods for solving common problems when using glue valves:


1. Oral blockage

Reason: The needle holes of the fully automatic glue filling machine were not completely cleaned, and impurities were mixed into the chip, resulting in clogging of the holes. Incompatible adhesives were mixed, resulting in low or no adhesive output

Solution: Replace the clean needle, replace the high-quality patch, and ensure that the brand number of the patch is correct

2. Rubber valve leakage

Reason: The needle diameter used in the fully automatic glue filling machine is too small. A needle that is too small will affect the exhaust bubble action of the rubber valve when it starts to be used, affecting liquid flow and causing back pressure. As a result, the rubber valve will leak soon after it is closed

Solution: Replacing the large needle can solve this problem. In addition, the air in the liquid may leak after the rubber valve is closed. It is best to remove the air in the liquid in advance, or use rubber that is not easily prone to bubbles, or centrifuge the rubber before use

3. The flow rate is too slow

Reason: The pipeline of the fully automatic glue dispenser is too long or too narrow, the air pressure at the nozzle is insufficient, and the dispensing flow rate is too slow

Solution: Change the distributor pipeline from 1/4 to 3/8, the shorter the pipeline, the better. In addition, improve the rubber port and air pressure, and accelerate the flow rate

4. There are bubbles in the fluid

Reason: The excessive fluid pressure and short valve opening time of the distributor may cause air to seep into the liquid and produce bubbles

Solution: Reduce fluid pressure and use a tapered needle

5. The size of the glue is inconsistent

Reason: The pressure cylinder and air pressure of the fluid stored in the fully automatic glue filling machine are unstable, and the glue is uneven and of different sizes

Solution: Do not insert pressure into the low-pressure section of the pressure gauge. The control pressure of the rubber valve should be at least 60psi or above to ensure the stability of the rubber. Finally, check the dispensing time. The dispensing is unstable within 15/1000 seconds, and the longer the dispensing time, the more stable the dispensing becomes

The above content is about the common causes and solutions of faults in fully automatic glue filling machines, and I believe everyone is aware of it. The common problems of automatic distributors can be large or small, and users can quickly solve these problems as long as they master the correct solutions.

The editor of HOLS (Suzhou) learned that in industry applications, all machines and equipment used for glue pouring, coating, spraying, pouring, and sprinkling are collectively referred to as glue pouring equipment. The application of gluing equipment is very extensive, and it has been widely applied to any process involving gluing technology and fluid control in industrial production


The semi-automatic glue filling equipment can be set in two modes

manual and foot. It can quantitatively dispense glue with the same amount each time, and is easy to operate. It also has a vacuum suction function that can adjust the negative pressure to 0.6 kilograms to ensure that glue with lower concentrations does not drip, and can prevent glue with higher concentrations from drawing. Dripable liquids include quick drying glue, red glue, anaerobic glue, black glue, silicone, SMT red glue, yellow glue, silver glue, silicone, epoxy resin, screw locking glue, lubricating oil, and flux

Fully automatic gluing equipment

The automatic gluing device has a production efficiency several to ten times that of manual gluing. Human machine interface, intuitive and convenient operation. Equipped with spatial 3D function, it can not only walk any chart on a plane, but also walk spatial (multiple planes) 3D maps, Equipped with USB interface for program transmission between different machines. Equipped with vacuum suction function, ensuring no glue leakage or wire drawing. Can be used with a glue filling valve and a large capacity pressure bucket. To improve production capacity efficiency and competitive advantage, equipment can be added according to process requirements

Two component gluing equipment

Also known as dual liquid gluing machine, AB gluing machine, etc., a dual liquid type gluing system (gluing machine) consists of three parts: two pressure buckets (mainly used to provide and store two different types of glue to the gluing valve), and an AB gluing valve (mainly used to mix two types of glue together in different proportions, and after a certain period of time, they will react and solidify), There is also a controller, also known as a glue dispenser (whose main function is to control the amount, frequency, and accuracy of glue dispensing)

Thread glue dispensing equipment

Gluing method: apply glue to each pair of screw teeth one by one; The glue application is accurate and consistent, and the number of teeth and the position of glue application can be set arbitrarily. The improved gluing structure avoids scratching the product with the gluing needle, and avoids tooth jumping due to product errors (there are teeth that have not been glued to the gluing position). The humanized design avoids the potential harm of equipment to personal health. Optional automatic material return function for even and stable dispensing, compact size, and convenient operation of non-metallic material storage device, ensuring that the adhesive material does not thicken over time

Silicone Gel Filling Equipment

Silicone gel filling equipment is independently designed for silicone and other adhesives with poor fluidity and high viscosity. The HOLS (Suzhou)  editor believes that it is particularly suitable for filling and packaging silicone and glass glue products with a volume of 330 milliliters per barrel.

The editor of HOLS (Suzhou) will explain the main components of a small vacuum AB automatic glue filling machine.

1. Rubber storage bucket

Select the corresponding functions based on the characteristics of the adhesive and customer process requirements.

The above is the understanding of the main components of the small vacuum AB automatic glue filling machine by the HOLS (Suzhou)  editor.

According to the editor of HOLS (Suzhou) , a vacuum gluing machine is a device used for gluing in a vacuum environment. The biggest difference compared to ordinary forms of glue dispensers is in terms of vacuum pumping, which directly affects the quality of the product. The main application industries include automobile manufacturing, capacitor coil gluing, etc. At the same time, the equipment has good recyclability, which improves production efficiency.

A vacuum gluing machine is based on a regular gluing machine, which extracts all the air from the pipeline pump body to prevent foaming. If the resin produced by the fully automatic vacuum gluing machine still has bubbles, it may be due to the following reasons:

1. The vacuum pump equipped with the gluing machine is not easy to use and cannot remove the bubbles
2. The glue dispenser did not vacuum and defoaming the resin before dispensing
3. Due to the high viscosity of resin adhesive, the vacuum defoaming method needs to be improved
4. It is related to glue and requires secondary defoaming
