Description

Technical Field

[0001] This utility model relates to the technical field of tin coating equipment, specifically a tin coating equipment for LED lamp production. Background Technology

[0002] An LED light is an electroluminescent semiconductor chip that is cured onto a support using silver or white glue. Then, silver or gold wires connect the chip to the circuit board, and the perimeter is sealed with epoxy resin to protect the internal core wires. Finally, a housing is installed. Therefore, LED lights have good shock resistance. The tinning equipment used in LED light production is a device used to apply solder paste during the LED light production process, designed to improve the uniformity of the coating and reduce waste.

[0003] In the LED lamp production process, the tin coating technology mainly involves core links such as automated adjustment, uniform coating, impurity cleaning and recycling. By cooperating with the adjustment component and the pressing component, the soldering position can be adaptively adjusted, and the amount of solder paste extruded can be precisely controlled. Some devices adopt the design of sliding groove and sliding block, which allows the tin coating rack to move laterally, ensuring that the solder paste evenly covers the surface of the circuit board. The scraper component rolls on the template surface and changes the scraper angle to achieve bidirectional scraping, which improves uniformity and reduces solder paste residue.
