Description

Technical Field

[0001] The utility model relates to the technical field of tin coating in the production and processing of LED lamps, and in particular to a tin coating device used in the production and processing of LED lamps. Background Art

[0002] In the production process of LED light strips, solder paste is usually first applied to the circuit board through a steel mesh with holes, and then the lamp beads are installed on the corresponding positions of the circuit board coated with solder paste. The circuit board is then heated to harden the solder paste to achieve the welding of the lamp beads. Therefore, the solder paste coating process is very important. When applying solder paste, the existing LED tinning machine first places the solder paste on the steel mesh, and scrapes the surface of the steel mesh with a scraper to make the solder paste fall into the holes on the steel mesh.

[0003] In the prior art, in order to ensure that the holes in the steel mesh can be filled with solder paste, a large amount of solder paste is pre-placed on the surface of the steel mesh. When the scraper moves, the solder paste is squeezed and overflows to the two ends of the scraper, causing the solder paste on the steel mesh to become less and less. After the solder paste coating is completed, a large amount of solder paste remains on the steel mesh and the scraper. For this reason, we propose a tin coating device for the production and processing of LED lamps. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. Through the tin coating and leveling mechanism, the solder paste is poured into the feed port of the tin coating rack, so that the solder paste slides down along the inner wall of the feed port and evenly falls onto the circuit board in the operating rack from the discharge port. Then, the sliding block slides in the sliding groove, driving the tin coating rack to slide to the right along the inside of the operating rack, and the solder paste is evenly coated on the circuit board. Compared with the existing spraying method, the solder paste of this device is more evenly coated, reducing the waste of solder paste.
