A welding device for solar cell production and processing

Abstract

This invention discloses a welding device for the production and processing of solar cells, relating to the field of welding processing technology. It includes a machine tool with a welding mechanism mounted on its top, a positioning mechanism on one side of the welding mechanism, and a pre-layout mechanism mounted on the top of the machine tool. In this invention, a worker places the solar cell into a frame. The positioning frame uses an electromagnet to control a flexible strip to support the solar cell. After being placed into the frame slot, a coil of tin-plated copper strip is fed in. It unfolds via a guide block and, upon reaching the edge, is triggered by a sensor to cut the strip. A roller presses down and a push rod pushes forward, embedding the copper strip into the gap of the flexible clamp. The rotating disc rotates 90° to above the positioning frame. As the roller rolls, the copper strip falls off, and the clamps force it into the grid lines for multi-row laying. After the positioning frame is moved to the base plate and installed, the welding head uses laser welding to weld the grid lines. After welding, the head is rotated 180°, the top flexible strip is retracted, and welding continues on the back side. The copper strip coil of the welding head eliminates the need for a pre-layout step.

Description

Technical Field

[0002] Solar cell welding is a core step in solar module production. Its function is to connect the positive and negative electrodes of individual cells through conductors (welding strips) to form series or parallel circuits, thereby realizing the collection and output of electrical energy. The welding quality directly affects the power, reliability and service life of the module. Solar cell welding equipment is an indispensable core equipment in solar module production, and its performance and stability directly determine the quality, production efficiency and manufacturing cost of the module.

[0003] The positioning, welding, and flipping functions of solar cell welding equipment are often distributed across multiple machines. The cells need to be transferred between different machines, which not only increases the floor space but also extends the production cycle. Furthermore, the cells are easily damaged by bumps during the transfer process. When flipping the cells, it is often done manually or by simple mechanical means, which can easily lead to the cells shifting, falling, or being scratched. The cells need to be repositioned after flipping, which is time-consuming and affects consistency. Summary of the Invention

Both ends of the compression spring 437 are fixed to the surface of the connecting ring 436 and the inner wall of the connecting inner ring 435.A lower pressure shaft is rotatably connected to the inner wall of the coupling ring 436. The end of the lower pressure shaft is fixed to the inner side of the connecting frame 419. In the pre-processing component 42, the connecting frame motor 429 drives the winding component 427 to rotate and feed out the copper strip. It is guided to the stop edge 424 by the guide block 426. After the sensor 425 detects the copper strip, it triggers the cutter 423 to cut it precisely. The cooperation of various components realizes the automatic supply, positioning and cutting of copper strip, reducing manual operation. The displacement push rod 414 of the steering component 41 pushes the displacement table 411 to move along the low rail table 413. The rotating disk 412 adjusts its angle under the drive of the steering motor. The forward push rod 417 and the roller control push rod 418 cooperate to push the roller component 43. The multi-component cooperation realizes the horizontal, angle and height adjustment of the copper strip layout position, which can adapt to the grid line position requirements of different sized battery cells.

[0025] The working principle of the welding equipment used in the production and processing of this solar cell is described in detail below: During use, the operator places the battery cell into the frame component 32. The positioning frame 321, controlled by the electromagnet 325, supports the battery cell with the flexible belt 331. The positioning frame 321 is placed into the frame slot 422. The winding component 427 rotates to feed out the tin-plated copper strip, which unfolds through the guide block 426. When the copper strip reaches the stop edge 424, the sensor 425 sends a signal, and the copper strip is cut by the cutter 423. The roller component 43 presses down, and the forward push rod 417 pushes forward, embedding the copper strip into the gap between the clamping keys 432 on the surface of the flexible ring 431. The rotating disk 412 rotates 90° and moves above the positioning frame 321. As the roller component 43 rolls on the surface of the battery cell, the connecting ring 436 slides against the connecting inner ring 435. The top shaft 434 extends outward to control the top plate 433 to squeeze the flexible ring 431, increasing the gap of the clamping keys 432. The copper strip falls off, and the clamp key 432 squeezes the copper strip into the grid line to achieve multi-row layout. The staff moves the positioning frame 321 to the base plate 313 and pushes in the connecting shaft 314 for installation. The welding mechanism 2 performs laser welding on the battery cell. After the grid line welding is completed, the flipping motor 312 flips the positioning frame 321 180°. Before the motor flips, the upper electromagnet 325 sends a signal with the same pole as the permanent magnet 326. The permanent magnet 326, along with the unfolding rod 332, pops out to the other end and attracts the electromagnet 325 at the other end. After the flip is completed, the magnetic pole of the upper electromagnet 325 changes and pops out the permanent magnet 326. The flexible strip 331 is retracted, and the battery cell flip is completed. The welding mechanism 2 welds the back of the battery cell. The copper strip roll 227 installed on the outer surface of the welding head 223 can eliminate the need for the staff to pre-lay tin-plated copper strip during welding.
