Description

Technical Field

[0001] The present invention relates to the technical field of series machines. Specifically, it particularly relates to a solder tape clamping and transfer mechanism and a series machine applied to BC solar cell wafers. Background Art

[0002] In a BC series device, since the solder tape for BC solar cell wafers is a flat solder tape, after the solder tape is uniformly prepared on the solder tape preparation platform, all the prepared solder tapes need to be clamped and transported by a solder tape clamping and transfer mechanism, and the solder tapes required for a string of BC solar cell wafers are laid on the BC solar cell string at one time. Since the clamping method for the flat solder tape is different from that of the traditional round solder tape, the clamping jaws on both sides of the round solder tape need to apply a relatively large force to clamp it to prevent the solder tape from falling off during the process of pulling the solder tape, and only one end needs to be clamped to lay the solder tape on the solar cell wafer. However, the flat solder tape has been cut on the solder tape preparation platform, and both ends of each solder tape need to be clamped. Moreover, the solder tape is prone to torsion when being clamped, resulting in the situation of offset grid, inaccurate placement or misalignment when placed on the BC solar cell wafer, and even damage to the flat solder tape during the clamping process. Therefore, a solder tape clamping and transfer mechanism and a series machine applied to BC solar cell wafers are provided to solve the above problems. Summary of the Invention

The positions of multiple solder tape clamping mechanisms 33 respectively correspond to the prepared solder tapes on the solder tape preparation platform. The jaw driving motor 321 drives the transmission shaft 322 to rotate a certain angle. The transmission shaft 322 causes the two transmission bearing assemblies 3331 to move away from each other. The two transmission bearing assemblies 3331 respectively drive the first push block 3332 and the second push block 3333 to move away from each other synchronously through the first elastic member 3334, and at the same time compress the first elastic member 3334 to accumulate a restoring force; the first push block 3332 and the second push block 3333 respectively drive the fixed jaw 3321 and the jaw seat 3322 to move away from each other, thereby driving the fixed jaw 3321 and multiple movable jaws 3323 to open relatively; the lifting movement component 20 drives the clamping and pressing component 30 to descend, and then the jaw driving motor 321 drives the transmission shaft 322 to return to the initial position. The first push block 3332 and the second push block 3333 move towards each other under the elastic restoring force of the first elastic member 3334. They respectively drive the fixed jaw 3321 and the jaw seat 3322 to move towards each other, thereby driving the fixed jaw 3321 and multiple movable jaws 3323 to clamp the corresponding solder tapes; then, the transverse movement component 10 and the lifting movement component 20 cooperate to transport the clamping and pressing component 30 holding the solder tape above the BC battery wafer string to correspond to the grid lines of the BC battery wafer. At the same time, the telescopic cylinder 352 contracts, which successively drives the lower pressure rod main body 3532, the lower pressing plate 343, the elastic pressing column structure 341, and the solder tape pressing structure 342 to move downward. The solder tape is flattened corresponding to the grid lines of the BC battery wafer through the pressing needle 3422. Then, the jaw driving mechanism 32 synchronously drives multiple solder tape clamping mechanisms 33 to release the corresponding solder tapes. The telescopic cylinder 352 extends, and the pressing needle 3422 moves upward to release the pressing operation on the solder tape, thereby completing the solder tape laying operation for a string of BC battery wafers.
