Three problems in dispensing mobile phone screen

Mobile phones are high-tech products, and the fear is that there will be quality problems. Mobile phone screen dispensing problems will lead to the scrapping of mobile phone screen. Proper dispensing equipment is needed to ensure the quality of mobile phone screen and mobile phone packaging. For example: the use of mobile phone screen dispensing, fully automatic dispensing function to improve the quality and speed of mobile phone screen dispensing, reduce the quality problems of mobile phone.

1. Dispensing deviation

Dispensing deviation is a common problem. There are two reasons for this problem. First, there are program errors. Second, there are problems with dispensing accessories. The latter is common. For example, dispensing needle deviation and low glue concentration are factors affecting dispensing quality. In order to improve the quality of mobile phone screen dispensing, it is necessary to do a good job in the maintenance of the automatic dispenser and the adjustment of the mechanical arm every day.

2. Glue leakage

The glue leakage of the automatic dispenser is easy to cause the glue to drop outside the scope of the mobile phone screen dispensing, which will affect the quality of the mobile phone screen. The glue leakage may be caused by the back pressure formed by the air pressure and the colloid. If the back pressure is too strong, the air pressure can not absorb the glue back. It is necessary to replace a larger dispensing needle to solve this problem.

3. Glue drawing of dispenser

Drawing is also an easy problem in the dispensing industry. Drawing is caused by the excessive concentration of glue. Therefore, when preparing glue for each product by the automatic dispenser, it is necessary to pay attention to the receiving degree of glue viscosity of each product. Of course, the dispensing needle and air pressure should not be too small, which may lead to wire drawing problems, and wire drawing also has glue problems For example, if hot melt adhesive is not suitable for mobile phone packaging, but pur hot melt adhesive is used for screen dispensing, then automatic dispensing machine will easily lead to glue drawing.
