[0002] Photovoltaic welding tape is used to connect the solar cells of photovoltaic modules, playing an important role in conducting electricity and gathering electricity. After production, the solar photovoltaic welding tape needs to be wound and reeled for easy storage and transfer. The existing photovoltaic welding tape is mainly wound by a reel. The worker puts the reel on the working shaft of the reel, fixes the solar photovoltaic welding tape to the reel, and starts the reel. The working shaft of the reel drives the reel to rotate and reel the welding tape.

[0003] However, when the winder is winding the welding tape, the workers cannot work. When the winding is completed, the winder can be turned off. When the reel stops rotating, the workers cut the welding tape, take out the reel full of photovoltaic welding tape, put in a new reel, and repeat the operation. The efficiency of solar photovoltaic welding tape winding is low. In view of this, we propose an automatic reel changing device for solar photovoltaic welding tape production. Utility Model Content

The utility model arranges the reel-changing assembly 4, and the three reeling assemblies 5 are arranged in a ring-shaped manner at equal intervals on the front of the reel-changing assembly 4, so that when the reeling assembly 5 reels the welding ribbon, the worker can take out the reeled solar photovoltaic welding ribbon and replace it with a new reel, which saves time, improves the reeling efficiency of the solar photovoltaic welding ribbon, and solves the current technical problem of low reeling efficiency of the solar photovoltaic welding ribbon.

[0023] Specifically, the roll changing assembly 4 includes a turntable 401, a rotating rod A402 is fixedly arranged at the center of the turntable 401, the head end of the rotating rod A402 passes through the front of the machine base 1 and is fixedly connected to the output end of the roll changing power mechanism 2, and the connecting part of the rotating rod A402 and the machine base 1 is rotatably connected through a bearing. As a preferred embodiment of the utility model, the utility model can drive the rotating rod A402 to rotate through the above arrangement, thereby indirectly driving the turntable 401 to rotate.

[0024] Furthermore, the winding assembly 5 includes a rotating rod B501, the head end of which passes through the inside of the rotating disk 401 and the front of the machine base 1 in sequence and extends to the inside of the machine base 1 and is fixed with an input gear 502, and the rotating rod B501 is rotatably connected to the rotating disk 401 through a bearing. As a preferred embodiment of the utility model, the utility model, through the above arrangement, allows the input gear 502 to be arranged inside the machine base 1 and can be connected to the winding power mechanism 6 inside the machine base 1, so that the winding power mechanism 6 can drive the rotating rod B501 to rotate independently.

[0025] Furthermore, the winding power mechanism 6 includes a cylinder 601, a fixed end of the cylinder 601 is fixedly connected to the inner wall of the base 1, a connecting block 602 is fixedly provided at the free end of the cylinder 601, a motor 603 is fixedly provided on the connecting block 602, an output gear 604 is fixedly provided at the output end of the motor 603, and the input gear 502 is meshed with the output gear 604 as a preferred embodiment of the utility model.

[0026] In addition, the tooth block heads of the input gear 502 and the output gear 604 are in a pointed shape, and the rotation axes of the input gear 502 and the output gear 604 are located on different horizontal lines. The utility model sets the tooth block heads of the input gear 502 and the output gear 604 in a pointed shape, and sets the rotation axes of the input gear 502 and the output gear 604 to be located on different horizontal lines, so that when the input gear 502 and the output gear 604 are in contact, the tooth block head of the output gear 604 pushes against the tooth block head of the input gear 502 to cause the input gear 502 to rotate slightly and then mesh with the output gear 604, thereby avoiding the situation where the tooth block heads of the input gear 502 and the output gear 604 abut against each other when they are in contact, thereby preventing the input gear 502 and the output gear 604 from being unable to mesh.

[0027] Working principle: When the solar photovoltaic welding tape needs to be rolled up, the reel is placed on the rotating rod B501, and the winding power mechanism 6 is started. The cylinder 601 extends to push the connecting block 602, the motor 603 and the output gear 604 to move forward as a whole. The tooth block heads of the input gear 502 and the output gear 604 are pointed, and the rotation axes of the input gear 502 and the output gear 604 are located on different horizontal lines, so that when the input gear 502 and the output gear 604 are in contact, the tooth block head of the output gear 604 pushes against the tooth block head of the input gear 502 to promote The input gear 502 rotates slightly and meshes with the output gear 604. The motor 603 receives a signal and starts, driving the rotating rod B501 and the reel thereon to rotate and reel the solar photovoltaic welding tape. When the motor 603 rotates to the set number of turns, it stops automatically, and the cylinder 601 retracts to separate the input gear 502 from the output gear 604. At this time, the reel-changing power mechanism 2 receives a signal and starts, driving the rotating disk 401 to rotate 120°. At this time, the reeling power mechanism 6 receives a signal and repeats the above action to push the input gear 502 to mesh with the output gear 604. At this time, the worker cuts the solar photovoltaic welding tape and fixes the end of the solar photovoltaic welding tape to the reel to be rotated. The motor 603 receives a signal and starts, driving the rotating rod B501 and the reel thereon to rotate and reel the solar photovoltaic welding tape. During this process, the worker can store the rolled solar photovoltaic welding tape, and take out a new reel and put it on the rotating rod B501, and repeat the operation.
