Embodiment 1

[0023] Such as figure 1 , 2 As shown, a component welding device that can prevent component power reduction, it includes:

[0024] Component automatic stringer 6, component automatic stringer 6 has a welding light source;

[0025] Pattern plate 1, when the component to be welded 5 is located at the welding station, the pattern plate 1 is arranged between the welding light source and the component to be welded 5, and the pattern part of the pattern plate 1 is hollowed out, and the rest are solid. It is a light-transmitting groove 2 opened on the pattern plate 1 at a position corresponding to the busbar line of the assembly 5 to be welded. In this way, when soldering, soldering is only performed at the position of the main grid line where the light reaches, and other parts of the battery that do not need to be soldered can avoid light, thereby avoiding the reduction of cell efficiency and component power caused by light-induced attenuation.

[0026] The pattern plate 1 is sup...

Embodiment 2

[0030] A component welding apparatus that prevents component power reduction, comprising:

[0031] Component automatic stringer 6, the component automatic stringer 6 has a welding light source;

[0032] Filter glass, when the component to be welded 5 is located at the welding station, the filter glass is arranged between the welding light source and the component to be welded 5, and the filter glass is used to filter out the light with a wavelength of 300nm to 1200nm emitted by the welding light source , which can also achieve the effect of avoiding light-induced attenuation and module power reduction;

[0033] The filter glass is supported by the bracket 4 on the transfer assembly 7 for transferring the assembly to be welded 5 and on which a welding station is arranged.

Embodiment 3

[0035] A component welding apparatus that prevents component power reduction, comprising:

[0036] Component automatic stringer 6. The component automatic stringer 6 has a welding light source. When the component 5 to be welded is located at the welding station, the welding light source is set above the component 5 to be welded, and the wavelength range of the welding light source is 1200nm<wavelength ≤2500nm light. When welding, the light emitted by the welding light source only shines on the main grid line of the battery and is not absorbed by the battery, thereby avoiding the reduction of battery efficiency and component power.

Abstract

The invention discloses an assembly welding device capable of preventing assembly power from being lowered. The assembly welding device comprises an automatic assembly series-welding machine and a patterned plate, wherein the automatic assembly series-welding machine is provided with a welding light source; when a to-be-welded assembly is positioned on a welding station, the patterned plate is arranged between the welding light source and the to-be-welded assembly, the patterned part of the patterned plate is hollow, and the rest part of the patterned plate is solid; the patterned part is a light transmission slot formed in a position, corresponding to a main grid line of the to-be-welded assembly, of the patterned plate. The assembly welding device disclosed by the invention can be used for avoiding a phenomenon that the battery efficiency and the assembly power are lowered due to light-induced degradation caused by illumination influences of a battery, and also can be used for realizing industrial automation, lowering the production cost and meeting the industrial production needs while guaranteeing the high output power of the assembly.

Description

technical field [0001] The invention relates to a component welding device capable of preventing component power reduction, and belongs to the technical field of solar cells. Background technique [0002] At present, in the field of photovoltaic industry, due to the increase of labor costs, more and more companies choose automation equipment to replace manual operations to reduce production costs. Among the many automatic control equipment, the component automatic stringer is one of them. In the past, in the process of manual welding of components, multiple processes of single welding and series welding were usually performed, which was time-consuming and laborious. The component automatic stringer can complete the welding in one step, saving time and effort, and greatly reducing production costs. At present, the automatic stringer of components on the market has several welding methods: infrared heating, hot air heating, and directional heating. Photovoltaic manufacturer...
