[0002] In the field of photovoltaic module production, the welding and arrangement equipment technology of busbars has become increasingly perfect. A busbar cutting device is disclosed in the Chinese Utility Model CN215238118U previously applied by the applicant. This busbar cutting device is rapidly applied to the arrangement equipment of busbars and is stably used.

[0003] However, in the case that the busbar arrangement equipment needs to be continuously replaced, it cannot be stopped to rethread a new busbar in actual production. Generally, the end of one busbar and the initial section of the next busbar are welded together. However, the overlap position of such welding cannot be actually used on photovoltaic modules because the thickness does not meet the standard. Therefore, it is urgently needed to realize the cutting of the overlap position of the busbar on the busbar arrangement equipment. SUMMARY

[0004] In order to solve the problems in the prior art, the application provides a busbar overlap position sensing and cutting device, which realizes the sensing and cutting of the overlap position under the premise of ensuring the stability of the previous cutting structure.

[0006] The overlap sensing device is arranged at the front end of the cutter device. When the overlap sensing device senses the overlap position, the cutter unit will cut off the overlap position at the predetermined position in the subsequent busbar feeding process, so that the overlap position is cut off from the busbar, realizing the function of feeding without stopping and cutting off the overlap position without stopping.

[0015] Through the setting of the two guide wheels, the two guide wheels can also serve as compression guide wheels to compress the bus bar when there is no lap joint position in normal times. When the lap joint position passes through the middle of the two guide wheels, the lap joint position will be thicker than the general bus bar, and thus the other guide wheel will be lifted upward, so as to drive the trigger part on the other guide wheel, and thus the sensing switch is triggered, and the lap joint position is sensed.

[0016] Specifically, the elastic sliding part comprises a mounting block, a spring is arranged in the mounting block, one end of the spring abuts against the inside of the mounting block, and the other end of the spring abuts against the other guide wheel.

When the lap joint position passes between the two guide wheels, the lap joint position will be thicker than the general bus bar, and thus the other guide wheel will be lifted upward, thereby driving the trigger part on the other guide wheel, and triggering the sensing switch, so that the lap joint position is sensed.
