AI Technical Summary

Technical Problem

During the assembly of existing LED lighting devices, the screw fixing method results in low production efficiency and high cost. It is difficult to ensure the fit and sealing between the lens plate and the base, and it is difficult to achieve automated production.

Method used

The lens plate and the base are connected by interference fit, and the plug-in position is filled with sealant. Combined with the edge and middle fastening structure, the pressure piece is used to form an interference fit, eliminating the need for screw connections and sealing rings, and realizing fully automated production.

Benefits of technology

It improves production efficiency, reduces material and labor costs, ensures the close contact and sealing effect between the lens plate and the base, improves the waterproof, heat dissipation and light distribution performance of the light-emitting device, and realizes fully automated production.

Abstract

The present invention discloses a method and equipment for producing a light-emitting device. The method for producing a light-emitting device includes the following steps: 1. Placing a light-emitting board on a base. 2. Placing a lens board on the base so that the lens board is aligned with the interference fit area on the base. 3. Applying extrusion force to the lens board so that an interference fit is formed between the lens board and the base. The present invention completes the fully automatic connection between the lens board and the base by pressing to form an interference fit; on the one hand, this method can save the material and labor costs of the traditional screw connection method, and on the other hand, it can make the lens board cling to and squeeze the light-emitting board under the action of the friction force generated by the interference fit, while improving the light distribution effect of the lens board and the fit between the light-emitting board and the base. In addition, the present invention achieves a double sealing effect by filling sealant at the plug-in position of the lens board and the base, and filling sealant in the sealing groove formed between the lens board and the base.
