Description

Technical Field

[0001] This application relates to the field of photovoltaic soldering strip tinning device technology, and in particular to an automatic photovoltaic soldering strip tinning device. Background Technology

[0002] The manufacturing process of photovoltaic solder ribbon requires tin plating, which necessitates the continuous addition of tin blocks to the tin plating bath. Patent application number 201922446021.7 discloses an automatic tin-adding device and a photovoltaic solder ribbon tinning machine, belonging to the field of photovoltaic solder ribbon production technology. The photovoltaic solder ribbon tinning machine includes an automatic tin-adding device. This device comprises a tin furnace, a guide bracket, a hopper, and a feeding mechanism. The guide bracket has a guide groove, and its end extends into the tin furnace. Heat from the tin furnace is transferred to the end of the guide bracket, melting the tin bars in the guide groove and allowing them to flow into the tin furnace. The hopper stores the tin bars and is located on one side of the guide bracket. The feeding mechanism includes a stand and a pushing component mounted on the stand. The stand is located on one side of the guide groove. When tin needs to be added, the pushing component transports the tin bars from the hopper into the guide groove. The tin-adding device can only feed the stored tin bars into the tin furnace one by one. The tin bars need to be replenished manually and continuously. Furthermore, the tin bars entering the molten tin furnace will cause large fluctuations in the molten tin, which will affect the tin plating process. Summary of the Invention
