In the manufacture of round bulb lamp, a round of built-in sealant filling should be carried out, which has the effect of waterproof, heat dissipation and protection. The corresponding fittings should be used to control the accuracy and flow rate of the bulb lamp filling, and the fixed-point glue control at the position of the quasi-glue filling should be used to glue the filling surface evenly. The tapered needle is recommended to be used as a pair. Uniform glue filling fittings inside bulb lamp can play a certain anti-scratch effect and control the flow rate of glue filling accurately. It can also be used in filter glue coating and other links to improve fixed-point glue control.

Selection of Conical Needle for Inside Sealing Filling of Bulb Lamp

 

Among many dispensing needles, only conical needle is more suitable for the glue filling effect of bulb lamp. Because the lampshade material of bulb lamp is made of glass and easy to scratch or break when contacting with hard objects, this damage is permanent and has obvious effect on the illumination effect. Therefore, it is not recommended to use ordinary metal needle to control glue filling glue and PP material cone. The conical structure can enhance the effect of glue flow. The fixed-point glue control effect can be implemented after setting parameters of the controller. It can also be used in batch manufacturing of bulb lamp glue and filter glue.

The effect of glue filling on spherical foams

 

Because the structure of bulb lamp is simple and needs some protective measures to improve its service life, epoxy resin and other resin glue are commonly used as protective measures. After glue filling, it has good waterproof and heat dissipation protection. It has strong resistance to dust and water in the air. It can be applied to bulb lamp glue filling and filter glue coating. For many production lines, in order to prevent the effect of fixed-point control glue filling on bulb lamp products, when assembling dispensing valves and tapered needles to control flow, the glue should be stirred evenly to avoid affecting the effect and quality of use.

Special LED dispensing machine should be selected for batch glue filling of bulb lamp. Multiple round bulb lamp can be placed in multi-station circular groove for glue filling. Conical needle made of soft PP material is recommended for glue filling and scratch prevention of various products.
