What are the common problems with glue dispensers and how can these problems be solved?

What are the common problems with glue dispensers? During the operation of the glue dispenser, there may be some problems, commonly including the following. What should we do when encountering these problems

1. Uneven glue dispensing

During the product dispensing process, if the dispensing machine malfunctions due to uneven glue dispensing, it can seriously affect the quality of product dispensing. The reasons for uneven glue dispensing include:


1. Insufficient accuracy of the metering pump

This manufacturer will definitely conduct testing before leaving the factory, and of course, newly purchased machines will also undergo verification upon arrival at the factory.
. If the machine has been used for a long time, it should also be verified regularly to avoid inaccurate measurement due to the prolonged use of the metering pump

2. Pipeline or mixing pipe blockage

Pipeline blockage refers to the possibility of waiting for a long period of time after outdoor use, and the outlet of the pipes and valves is not sealed, causing the glue to come into contact with air and solidify over time.


The blockage of the mixing tube refers to the residual AB in the mixing tube not being cleaned in a timely manner after use, resulting in changes in the cross-sectional area of the flow and uneven glue output.


Secondly, there are glue dispensing bubbles.

The phenomenon of glue dispensing bubbles is one of the common glue dispensing problems in the production process of products. The reasons for the occurrence of glue dispensing bubbles are as follows:

1. When glue is added to the storage bucket of the machine, there are already bubbles, so it is only necessary to vacuum the bucket after adding glue to remove the bubbles in the glue.

2. Bubbles generated by glue are generated by high-speed stirring during AB mixing. If this is the case, static stirring should be used instead of dynamic stirring

When purchasing a glue dispenser, recognize the principles of your own purchase. Here, I will share a few points:

1. Glue: Two component glue dispensers, such as epoxy resin AB glue, PU glue, and silicone.
. Single component glue dispensing machine

2. Gluing process: For small batches of glue, semi-automatic (such as foot control) is used. For large batches and irregular glue dispensing trajectories, a three-axis motion platform dispensing machine is selected, and the dispensing machine automatically completes the set trajectory

3. Cost: There are various glue filling solutions, and not all glue filling requires the use of machines. From a cost perspective, if a certain glue needs to use a machine that is too expensive, it can be considered to replace the glue
