The use of PU glue needs to understand the characteristics of this glue first. PU glue is different from ordinary glue and has strong stickiness. If PU glue is used in the general dispenser, the glue may be directly blocked in the transmission system and can not be used normally. So it is necessary to use the PU glue peristaltic LED dispenser to make the glue. PU glue peristaltic LED dispensing machine is built to solve this problem. In the manufacturing process, the dispensing machine uses some special metal materials. Special metal material has a strong non stick, making PU glue can be normal by PU glue dispenser for dispensing peristaltic LED product dispensing, also adopt mechanical drive form, strengthen the ability to control the glue, improves the precision of dispensing, and some parts still used in power screw rolling contact way, so as to reduce the friction resistance, but also extend the service life of the hose. The axis positioning system and the visual positioning system, in conjunction with the mechanical drive of this power mode, let the glue dispenser can make precision dot glue. The motor uses a servo system, making the PU glue peristaltic LED dispenser have the ability to repeat the glue. Therefore, the peristaltic LED glue dispenser can meet all the application requirements of PU glue.
