Description

TECHNICAL FIELD

It integrates a high-precision motion control system, an intelligent visual positioning module, a special dispensing valve, a stable glue supply unit and a programmable control system. According to the preset program and process parameters, the full-automatic dispensing equipment for LED can automatically complete the precise dispensing of adhesive to the specified position of LED lamp beads, LED modules, LED drive boards and other devices. The full-automatic dispensing equipment for LED can realize the automatic identification and calibration of the position of the device through the visual module, and is suitable for various types of glue such as silicone glue, epoxy glue and heat-conducting glue. The full-automatic dispensing equipment for LED not only ensures the precision, uniformity and consistency of dispensing, but also greatly reduces manual intervention, effectively improves the packaging reliability and production efficiency of LED products, and is a key core equipment for realizing the large-scale and standardized production of LED products.

[0003] The full-automatic dispensing equipment for LED has poor stability in conveying and dispensing of high-viscosity adhesive, and is prone to problems such as glue valve blockage and uneven dispensing amount. At the same time, the full-automatic dispensing equipment for LED has insufficient dispensing path planning and precise positioning ability for micro and special-shaped LED devices, and is prone to problems such as glue leakage and deviation. In addition, the full-automatic dispensing equipment for LED is difficult to quickly switch between multiple specifications and multiple forms of workpieces. In the prior art, a constant-temperature and pressure glue supply module is added. The adhesive is heated to an appropriate viscosity range by a temperature control unit. A screw type booster pump or a plunger type quantitative glue supply device is provided to replace the traditional air pressure glue supply, so as to realize the constant pressure and quantitative conveying of the adhesive, and avoid uneven dispensing caused by pressure fluctuation. However, the glue attached to the outer wall of the needle will drip or draw wire during dispensing, resulting in an increase in the volume of the glue point and irregular shape. The residual glue will fall off when it contacts the product again, forming unnecessary glue points or pollution. In addition, the unhardened glue accumulates and dries in the surface of the needle plate and the needle hole, gradually blocking the glue outlet hole and the precision motion parts. SUMMARY
