Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic welding strip processing, in particular to a positioning device used for photovoltaic welding strip processing. Background Art

[0002] Photovoltaic welding ribbon is also called tinned copper ribbon or tin-coated copper ribbon. It is divided into busbar and interconnection strip. It is used to connect the solar cells of photovoltaic modules and plays an important role in conducting electricity. When the photovoltaic welding ribbon is processed and produced, the welding ribbon needs to be rolled onto the welding ribbon reel. When the welding ribbon is rolled onto the welding ribbon reel, a positioning device needs to be used to position the welding ribbon reel, and then the welding ribbon reel is rotated for rolling;

[0003] In the prior art, a patent with authorization publication number CN 220165317 U discloses a positioning device for photovoltaic welding tape processing. During the winding process, when a welding tape roll needs to be released from its position and removed, it is necessary to remove the bolts between the T-frame and the U-shaped disassembly frame, and then lift the T-frame upward and trigger the pressing pin. At this time, one welding tape roll can be released from its position, and then it is necessary to remove the bolts between the U-shaped disassembly frame and the top plate, and then remove the U-shaped disassembly frame from the top plate. Then, one welding tape roll can be removed. The entire disassembly process is relatively cumbersome. If a single welding tape roll needs to be disassembled, the machine needs to be shut down. Otherwise, the drum cannot be disassembled during rotation, and the entire equipment is shut down, and other welding tape rolls cannot work, thereby reducing the processing efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a positioning device for photovoltaic welding tape processing, which is simple to operate and convenient for taking and placing the welding tape roll. At the same time, it avoids the trouble of shutting down the entire equipment when taking and placing a single welding tape roll, thereby improving the processing efficiency and effectively solving the problems in the background technology.

[0007] Furthermore, the telescopic transmission mechanism includes a shaft sleeve and a transmission rod, the shaft sleeve is rotatably connected to the frame, the transmission rod is slidably connected to the shaft sleeve up and down, and the support plate is fixed on the top of the transmission rod.

[0008] Furthermore, the telescopic transmission mechanism also includes a slide bar, which is fixed on the side of the transmission rod and is connected to the shaft sleeve in an up-and-down sliding manner.

[0009] Furthermore, the telescopic transmission mechanism also includes a spring, which is sleeved on the transmission rod and arranged between the support plate and the shaft sleeve.

[0010] Furthermore, the positioning mechanism includes a magnet block and an armature block. The magnet block is fixed on the top of the support plate, and the armature block is fixed on the end of the welding strip reel. The armature block is magnetically connected to the magnet block.

[0020] The positioning mechanism 5 includes a magnet block 51 and an armature block 52. The magnet block 51 is fixed on the top of the support plate 7, and the armature block 52 is fixed on the end of the welding tape reel 8. The armature block 52 is magnetically connected to the magnet block 51. The armature block 52 is separated from the magnet block 51 to remove the welding tape reel 8 from the support plate 7.
