Photovoltaic module diode tin pre-storage device based on crest welder

Abstract

The invention discloses a photovoltaic module diode tin pre-storage device based on a crest welder, and relates to the technical field of semiconductors, in particular to the photovoltaic module diode. The photovoltaic module diode comprises a mechanical arm and the crest welder, the mechanical arm is arranged above the crest welder, the clamping end of the mechanical arm is further provided with a photovoltaic module diode tin storage jig, the top face of a tin melting pool of the crest welder is further covered with a tin feeding housing, and the tin feeding housing and the top face of the tin melting pool of the crest welder are sealed. The photovoltaic module diode tin storage jig comprises a back plate and a cover plate, the back face of the back plate is fixedly connected with the clamping end of the mechanical arm, and several sets of grooves are formed in the front face of the back plate. According to the device, Tin is stored through wave crests, the tin storage thickness can be effectively controlled, the appearance and uniformity of tin materials are highly consistent, the situation of deformation of cooling fins is eradicated, the product yield is greatly improved, tin consumption is reduced, meanwhile, the thickness can be accurately adjusted, and welding of a building factory is extremely convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to photovoltaic module diodes. Background technique [0002] At present, photovoltaic module diode products need to pre-storage tin on the heat sink, so that the junction box factory can directly weld the photovoltaic module diode to the bus belt in the subsequent processing. [0003] In the prior art, the tin storage machine is usually used to feed the tin. The tin wire is placed above the heat sink, and then the soldering iron head of the tin storage machine moves from top to bottom. The soldering iron head first melts the tin wire into solder material, and the solder material sticks At the end of the soldering iron tip, the last end of the soldering iron tip to touch the heat sink, deposit the solder onto the surface of the heat sink. This method of tin delivery has the following disadvantages: 1. The efficiency of tin delivery is low; 2. The appearance and thickness of t...

Problems solved by technology

This method of tin delivery has the following disadvantages: 1. The efficiency of tin delivery is low; 2. The appearance and thickness of the solder material on the heat sink are not uniform enough, which leads to increased welding difficulty in the production process of the junction box factory and prolongs the welding time. , resulting in abnormal welding defects such as virtual soldering; 3. Due to the uneven solder material, the heat sink will be heated unevenly, resulting in thermal deformation of the heat sink, which will affect the quality of the photovoltaic module diode
