[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: through the synchronous movement and cooperation between the moving platform and the first pneumatic gripper and the second pneumatic gripper, the cylindrical batteries that fall onto the cylindrical battery holding platform are grasped by the first pneumatic gripper in multiple ways. After the grasping is completed, the moving platform drives the first pneumatic gripper and the second pneumatic gripper to move. At this time, the multiple cylindrical batteries grasped by the first pneumatic gripper are transported to the middle position of the cylindrical battery holding platform, and the moving platform drives the first pneumatic gripper and the second pneumatic gripper to move and reset again. At this time, the multiple cylindrical batteries located in the middle position of the cylindrical holding platform are located at the bottom end of the second pneumatic gripper. At this time, the second pneumatic gripper clamps and limits the multiple cylindrical batteries so that the insulating paper can be attached to the cylindrical batteries later.
[0015] The insulation paper is loosened by the rotation of the insulation paper roll wheel. The loosened insulation paper passes through one side of the punching knife fixing frame and is connected to the insulation paper traction support frame. The insulation paper also comes into contact with the punching knife assembly. When the first pneumatic gripper clamps multiple cylindrical batteries to the middle position of the cylindrical battery holding platform and is then clamped and limited by the second pneumatic gripper, the multiple cylindrical batteries are located on the other side of the insulation paper. At this time, the punching knife assembly is driven to move out from the punching knife fixing frame and punch the insulation paper. During the punching process, the insulation paper can be punched and attached to the positive terminal of the multiple cylindrical batteries. After the insulation paper is attached, the multiple cylindrical batteries are clamped and transported to the second conveyor belt and the punching knife assembly is reset in the movement cooperation between the moving platform and the second pneumatic gripper. The insulation paper traction support frame pulls the punched insulation paper so that the unpunched insulation paper can continue to move to one side of the punching knife fixing frame so that the cylindrical batteries can be punched and attached with insulation paper in the future.
[0016] When the second conveyor belt transports the cylindrical batteries to the cylindrical battery transport rack, the cylindrical batteries fall one by one into the chute. At this time, the first cylinder drives the first pusher block to push the cylindrical batteries in the chute one by one onto the third conveyor belt, and then the cylindrical batteries are transported again by the third conveyor belt.
[0017] The fourth cylinder drives the pusher to move on one side of the third conveyor belt, and the pusher can push the cylindrical battery into the limit frame during the movement.
[0018] When the pusher pushes the cylindrical battery into the cylindrical battery entry and exit limit frame, the pusher stops running. At this time, the cylindrical battery is horizontally placed inside the cylindrical battery entry and exit limit frame. The moving frame can drive the test probe to move on both sides of the cylindrical battery entry and exit limit frame to perform positive and negative connection tests with the cylindrical battery inside the cylindrical battery entry and exit limit frame. After the cylindrical battery test is completed, the pusher continues to move and pushes the tested cylindrical battery from inside the cylindrical battery entry and exit limit frame to the fourth conveyor belt for transportation.

At one end of the rack is a third conveyor belt 11 for transporting the cylindrical batteries pushed onto it. The third conveyor belt 11 is horizontally positioned on the second workbench 2. On one side of the third conveyor belt 11 is a cylindrical battery entry / exit limit frame 12 for testing the entry and exit limits of the cylindrical batteries. On the other side of the cylindrical battery entry / exit limit frame 12 is a fourth conveyor belt 13 for transporting the tested cylindrical batteries. On one side of the fourth conveyor belt 13 is a support platform 37, and on the support platform 37 is a third pusher block 39 for pushing the cylindrical batteries off the fourth conveyor belt 13. On the other side of the fourth conveyor belt 13 is a receiving box 14 for collecting and carrying the cylindrical batteries.
[0035] The first hopper 4 is equipped with a first traction wheel 19, which is located at the bottom of the first hopper 4. The first traction wheel 19 rotates at the bottom of the first hopper 4, thereby rotating the cylindrical batteries inside the first hopper 4 one by one and dropping them onto the first conveyor belt 8. The first conveyor belt 8 is equipped with a discharge limit frame 18, which is vertically located on one side of the first conveyor belt 8. A discharge channel is formed between the discharge limit frame 18 and the first conveyor belt 8, thereby allowing the cylindrical batteries transported on the first conveyor belt 8 to fall one by one onto the cylindrical battery retention platform 7 through the discharge channel.
[0036] An insulating paper traction support frame 6 is provided on one side of the cylindrical battery holding platform 7, and a moving platform 26 is vertically arranged on the front side of the insulating paper traction support frame 6. The insulating paper traction support frame 6 is vertically fixed on the first workbench 1, and a first pneumatic gripper 29 and a second pneumatic gripper 30 are vertically arranged on the left and right sides of the front side of the moving platform 26, respectively. The moving platform 26, together with the first pneumatic gripper 29 and the second pneumatic gripper 30, moves horizontally on the front side of the insulating paper traction support frame 6. Through the synchronous movement and cooperation between the moving platform 26 and the first pneumatic gripper 29 and the second pneumatic gripper 30, the paper falls onto the cylindrical battery holding platform 7. The cylindrical batteries on the battery holding platform 7 are gripped by the first pneumatic gripper 29. After the gripping is completed, the moving platform 26 moves the first pneumatic gripper 29 and the second pneumatic gripper 30. At this time, the cylindrical batteries gripped by the first pneumatic gripper 29 are moved to the middle position of the cylindrical battery holding platform 7. The moving platform 26 then moves the first pneumatic gripper 29 and the second pneumatic gripper 30 back to their original positions. At this time, the cylindrical batteries located in the middle position of the cylindrical holding platform 7 are located at the bottom of the second pneumatic gripper 30. The second pneumatic gripper 30 clamps and limits the cylindrical batteries so that the insulating paper can be attached to the cylindrical batteries later.
[0037] A punching cutter holder 15 is provided on the other side of the cylindrical battery holding platform 7, and the punching cutter holder 15 is fixed on the first worktable 1. A punching cutter assembly 27 is arranged laterally on one side of the punching cutter holder 15, and the punching cutter assembly 27 translates on one side of the punching cutter holder 15 and on the surface of the cylindrical battery holding platform 7. An insulating paper roll 20 is provided between the punching cutter holder 15 and the first worktable 1, and the insulating paper roll 20 is rotatably disposed inside the first worktable 1. The insulating paper roll 20 is wound with insulating paper (not shown in the figure), and the rotation of the insulating paper roll 20 loosens the outer insulating paper. The loosened insulating paper passes through one side of the punching cutter holder 15 and is connected to the insulating paper traction support frame 6 for traction transmission. The punching cutter groups 27 are in contact with each other. When the first pneumatic gripper 29 clamps and transports multiple cylindrical batteries to the middle position of the cylindrical battery holding platform 7 and then clamps and limits them by the second pneumatic gripper 30, the multiple cylindrical batteries are located on the other side of the insulating paper. At this time, the punching cutter group 27 is driven to move out of the punching cutter fixing frame 15 and punch the insulating paper. During the punching process, the insulating paper can be punched and pasted onto the positive terminal of the multiple cylindrical batteries. After the insulating paper is punched and pasted, the multiple cylindrical batteries are clamped and transported onto the second conveyor belt 9 in the moving cooperation between the moving platform 26 and the second pneumatic gripper 30, and the punching cutter group 27 is reset. The insulating paper traction support frame 6 pulls the punched insulating paper so that the unpunched insulating paper can continue to move to one side of the punching cutter fixing frame 15 so that the insulating paper can be punched and pasted onto the cylindrical batteries in the future.
[0038] A third cylinder 28 is provided between the punching knife assembly 27 and the punching knife fixing frame 15. The third cylinder 28 is located on the outside side of the punching knife fixing frame 15 and is driven to the punching knife assembly 27.

A take-up roller 25 is installed on one side of the connecting frame 23 and is also equipped with a first motor 24 that drives the take-up roller 25. When the insulating paper passes through the punching knife fixing frame 15, the insulating paper slides sequentially over the surfaces of the first traction roller 33, the second traction roller 34, and the guide roller 31, and finally wraps around the take-up roller 25. Thus, the punched insulating paper can be wound up by the driving cooperation between the first motor 24 and the take-up roller 25. During the winding process, the first traction roller 33, the second traction roller 34, and the guide roller 31 provide traction and guidance.

The second hopper 5 is provided with a second material traction wheel 35, which is located at the bottom of the inside of the second hopper 5 and rotates at the bottom of the inside of the second hopper 5. Thus, the rotation of the second material traction wheel 35 can rotate and bring out the cylindrical batteries inside the second hopper 5 one by one and fall onto the third conveyor belt 11 at the same time.

At this time, the cylindrical battery is horizontally placed inside the cylindrical battery entry / exit limiting frame 12. The movable frame 42 can drive the test probe 43 to move on both sides of the cylindrical battery entry / exit limiting frame 12 to perform positive and negative terminal connection tests with the cylindrical battery inside the cylindrical battery entry / exit limiting frame 12. After the cylindrical battery test is completed, the pusher 44 continues to move and pushes the tested cylindrical battery from inside the cylindrical battery entry / exit limiting frame 12 to the fourth conveyor belt 13 for transportation.
