Tin scraping device

Abstract

The invention discloses a tin scraping device which comprises a scraping plate assembly and further comprises a support, a lifting assembly and a reciprocating type driving mechanism, and an annular groove is formed in the side wall of the support; the lifting assembly is matched with the annular groove, and the scraping plate assembly is connected with the lifting assembly; the reciprocating type driving mechanism drives the lifting assembly to reciprocate along the annular groove, and the lifting assembly is connected with the reciprocating type driving mechanism; the annular groove comprises a first groove section for guiding the lifting assembly to translate, a second groove section, a first guide groove and a second guide groove; the second groove section is used for guiding the lifting assembly to return, and the height position of the second groove section is higher than that of the first groove section; the first guide groove is used for guiding the lifting assembly to descend into the first groove section from the second groove section, one end of the first guide groove is connected with the first groove section, and the other end of the first guide groove is connected with the second groove section; and the second guide groove guides the lifting assembly to ascend from the first groove section to the second groove section, one end of the second guide groove is connected with the first groove section, and the other end of the second guide groove is connected with the second groove section. The tin scraping device has the advantage of stable slag scraping.

Description

technical field [0001] The invention relates to a tin scraping device. Background technique [0002] In the electronics industry, molten tin is often used for tin protection and anti-oxidation treatment on copper wire soldering, or molten tin is used for cladding welding of wire ends to be welded. [0003] The surface of the molten tin liquid is in direct contact with the air, so it is easy to form an oxide film. The oxide film is a thin solid tin film, and the surface of the film also contains many impurities floating in the molten tin liquid. If the oxide film and floating objects on the surface are not scraped off, the thread to be protected will first contact the oxide film when it is immersed in the tin liquid. The oxide film will block the adhesion of the tin liquid to the thread, which will directly cause the tin to adhere weakly, There are problems such as incomplete adhesion of tin on the surface. At the same time, the curing film will also increase the resistance ...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the tin slag is manually scraped off by using a scraper. However, the temperature of the molten tin is usually above 250°C, which may easily cause burns or damage the scraper. When scraping off the oxide film of the tin liquid, it must be smooth and smooth. The immersion and lifting of the board should be done gently, otherwise the tin liquid will splash out of the container containing the tin liquid under the action of oscillation, causing burns to the operator and other personnel
