Problems solved by technology

However, a large number of practices have proved that there are many disadvantages in the existing automatic welding devices, such as the current automatic welding devices using hot air welding and laser welding, due to insufficient heating of the bus bar and lead wire, heat absorption of the pressure head or heating parts, the bus bar It is easy to cause problems such as virtual soldering, missing soldering and consistency of soldering appearance.
In particular, it is difficult to meet the relevant technical standards of solar cell components such as welding pull-out force and appearance consistency, which seriously affects the stability and reliability of solar cell components after installation.

Abstract

The invention discloses a battery string lead wire and bus bar interconnection device, which includes a welding module and a plurality of pressure head modules arranged above the welding module, the welding module includes a fixed base plate and is installed on the fixed The supporting plate on the base plate is equipped with a welding bearing module on the top of the supporting plate, and electric heating modules are installed on both sides of the supporting plate, and the electric heating module is used to heat the welding bearing module. The head module includes a fixed block and at least one thermal insulation pressing head connected to the bottom end of the fixed block. The battery string lead wire and bus bar interconnection device is compatible with various bus bar specifications, which improves the utilization rate of the interconnection device. While maximizing the welding pulling force, full welding traces are obtained, and the performance is stable and reliable. Not only Save manpower and better ensure quality. The invention also provides a battery string lead wire and bus bar interconnection process using the battery string lead wire and bus bar interconnection device.

Description

technical field [0001] The invention relates to the technical field of solar cell module welding, in particular to a device for interconnecting battery string leads and bus bars and an interconnection process. Background technique [0002] In the production process of solar cell modules, the process of placing the bus bar at the specified position of the battery string, and then welding the bus bar and the lead wires on the battery string together is called the interconnection process of the battery string lead wire and the bus bar. [0003] The traditional interconnection process of battery string leads and bus bars is mostly completed by manual welding with the help of laying equipment. The interconnection process of battery string leads and bus bars is a crucial process link in the packaging technology of solar cell modules. It needs to maintain a certain working speed at all times, and requires special personnel to inspect, maintain and repair the equipped hand-held elec...
