Welding strip positioning assembly

Abstract

The invention discloses a welding strip positioning assembly, which comprises a clamping jaw mechanism and a lifting driving mechanism, wherein the clamping jaw mechanism comprises a left movement output device and a right movement output device, the left movement output device and the right movement output device are respectively used for driving a plurality of front clamping jaws and a plurality of back clamping jaws to transversely move, the movement output ends of the left movement output device and the right movement output device are respectively connected with a first slide block and a second slide block, the first slide block and the second slide block are respectively and slidingly connected with a left movement slide guide and a right movement slide guide by the driving of the left movement output device and the right movement output device, the first slide block is fixedly connected with one end of a front clamping jaw base plate, the second slide block is fixedly connected with one end of a back clamping jaw base plate, the other ends of the front clamping jaw base plate and the back clamping jaw base plate are respectively and slidingly connected with the left movement slide rail and the right movement slide rail through a third slide block and a fourth slide block, the top part of the front clamping jaw base plate is provided with the front clamping jaws at intervals in the vertical direction, the top part of the back clamping jaw base plate is provided with the back clamping jaws, the lifting driving mechanism comprises a driving device, and the movement output end of the driving device is fixedly connected with a mounting plate. Through the method, the welding strip positioning assembly has the advantages that the welding strip is well positioned, and the deviation of the welding strip is avoided.

Description

technical field [0001] The invention relates to a positioning assembly, in particular to a welding strip positioning group. Background technique [0002] When welding solar cells into strings, the ribbon fixed on the reel is usually stretched through the clamping mechanism to the high-temperature preheating position by pulling, and the ribbon is cut off by a cutter, and the solar cells are cut off by hand. Put it in the high-temperature preheating position, make the grid line of the cell coincide with the welding strip, and heat and weld it by lowering the high-temperature lamp. The temperature of the preheating position is higher than 100°C. Very fine. During the welding process of the ribbon and the battery, because the ribbon on the back of the battery will be offset by the pressure of the ceramic rod of the lamp, the grid line on the back of the battery and the ribbon will often be offset during the welding process, resulting in poor welding .
