Description

A ribbon processing device

technical field

The invention relates to the technical field of solar cell string production, in particular to a welding strip processing device.

Background technique

Cell string welding is an important process in the production process of solar panels. It uses welding strips to weld the cells into battery strings. The welding strips play an important role in conducting electricity and collecting electricity. In the stringing process, usually one section of the ribbon is welded to the back of one of the two adjacent battery pieces, and the other section is welded to the front of the other battery piece. Due to the extremely thin and brittle structure of the silicon-based battery sheet, in the process of overlapping with the ribbon, the stress at the front and rear connections of the battery sheet is relatively large, and the risk of hidden cracks or even fragments is prone to occur. The pretreatment of "dotting" is performed on the ribbon, and the middle part of the ribbon is partially thinned to eliminate or reduce the risk of fragmentation of the battery sheet. In the prior art, the welding ribbon is generally placed in rolls, and before it is welded to the battery sheet, it first needs to undergo pretreatment processes such as stretching, shaping, dotting, and cutting. In actual production, multiple parallel ribbons need to be used in stringing battery cells, so the ribbon processing device needs to be able to process multiple ribbons at the same time.

A common ribbon processing device includes a rectangular tank, the stretching direction of each ribbon is parallel to the length direction of the tank, and the distribution direction of different ribbons is parallel to the width direction of the tank. Processing modules with different functions such as stretching, shaping, dotting, cutting, etc. are arranged along the length direction of the tank body. Each module includes a mounting frame erected on the tank body, and the mounting frame is composed of columns fixed on both sides of the width of the tank body and a beam connected between the two columns. A processing unit consisting of moving parts, cylinders and other components required for processing the welding ribbon is installed on the beam, and multiple processing units need to be arranged on one mounting frame to correspond to multiple welding ribbons distributed along the width direction of the tank. The above-mentioned welding ribbon processing device has at least the following defects: (1) When each welding ribbon is pulled out from the reel, it needs to pass through one by one under the beams and be accurately placed in the processing hole below each processing unit or In the slot, it takes manpower and time, especially when the number of welding ribbons to be processed is large and the tank body is wide, the operation is more difficult; (2) When the number of welding ribbons to be processed is large, the width of the beam also increases accordingly , the total weight of the processing unit also increases, and the straightness of the beam is significantly deteriorated under the pressure of gravity, especially the processing unit located in the middle of the beam will sink significantly, and the height of each processing unit is uneven, resulting in the level of processing effect of each welding strip Unevenness (such as uneven pressure, etc.), which seriously affects the production quality of battery strings, especially multi-parallel battery strings.
