[0002] The background art of the variable pitch double jaw for lithium batteries can be traced back to the field of mechanical engineering. Especially in the automated manufacturing and production processes, the jaw is one of the most important actuating components on the automated production line, used for clamping and transferring materials. During the production process of lithium batteries, the use of jaws can significantly improve production efficiency and quality.

[0003] According to a variable pitch double jaw picker disclosed in Chinese Utility Model Patent CN216189128U, it includes a jaw fixing plate, a linear slide, a slide fixing plate, a pair of connecting brackets symmetrically distributed, a pair of gripper cylinders, a pair of linear cylinders, and also includes several three-jaw fingers and several jaw molds; the slide rail of the linear slide is connected to the slide fixing plate, and the three-jaw fingers are arranged on the gripper cylinders; wherein, the connecting bracket is connected to the slider on the corresponding side of the linear slide, and the connecting bracket is connected to the rod of the linear cylinder. The linear cylinder is used to adjust the gap between the two gripper cylinders to adapt to the situation where the distance between two workpieces changes during grasping and releasing. By setting a pair of gripper cylinders, workpieces can be grasped in pairs. A pair of gripper cylinders are installed on the connecting bracket and are guided by the slide and driven by the linear cylinder, so that the position between the two jaws can be adjusted according to the distance of the grasped workpiece, well meeting the needs of the robot for automated production.

The variable pitch adjusting device 2 is used for clamping the assembled lithium battery 3. The photoelectric sensor 4 is used for detecting whether the clamping device 1 has completed clamping of the lithium battery 3.

[0030] As Figure 3 shown, as an optimization, the clamping device 1 includes a support plate I 11. A support plate II 12 is provided at the bottom of the support plate I 11. The support plate I 11 and the support plate II 12 are connected by a pneumatic telescopic cylinder 13. An external main shaft 14 is provided at the top of the support plate I 11. An inductive sheet 15 is installed on one side of the top of the support plate I 11. Correspondingly, a proximity switch I 16 is installed on one side of the support plate II 12.

[0031] By setting the pneumatic telescopic cylinder 13 to drive the connecting support plate I 11 and the support plate II 12, it is used to realize the clamping installation of the lithium battery body and the positive and negative electrodes. The external main shaft 14 is used for the clamping and transportation of the overall structure. The induction piece 15 and the proximity switch I 16 cooperate to stop the pneumatic telescopic cylinder 13 from working when the support plate I 11 and the support plate II 12 reach the specified distance.

[0032] As Figure 4 shown, as an optimization, the variable pitch adjusting device 2 includes a cylinder I 21. On both sides of the bottom of the cylinder I 21, mounting seats 22 are symmetrically arranged. The bottom of the mounting seat 22 is fixedly connected with a pneumatic finger 23. The pneumatic finger 23 is detachably connected with a clamping claw 24. A proximity switch II 25 is vertically arranged on one side of the clamping claw 24, and a photoelectric sensor 4 is arranged on the other side of the clamping claw 24.

[0033] The cylinder I 21 is used to drive the mounting seat 22 to move. The mounting seat 22 drives the pneumatic finger 23 arranged at the bottom to control the clamping claw 24 to perform separation and closing movements. The proximity switch II 25 vertically arranged on one side of the clamping claw 24 is used to detect whether the clamping claw 24 clamps the lithium battery 3, and the photoelectric sensor 4 is used to detect whether the clamping claw 24 moves up and down to the position where the lithium battery 3 is located.

[0034] As Figure 4 shown, as an optimization, a buffer pad I 26 is arranged inside the clamping claw 24.

[0035] The buffer pad I 26 is used to protect the clamping of the lithium battery 3 by the clamping claw 24 and avoid damage to the lithium battery 3 caused by excessive clamping force.

[0036] As Figure 4 shown, as an optimization, a buffer pad II 27 is arranged inside one side of the clamping claw 24, and the buffer pad II 27 fits the negative electrode when clamping the lithium battery 3.

[0038] As Figure 4 shown, as an optimization, the buffer pad II 27 is made of insulating material.

[0039] Working process or working principle:

[0040] Lithium battery assembly steps: Install the clamping device. The pneumatic telescopic cylinder 13 drives the support plate I 11 to perform relative movement with respect to the support plate II 12, so that the positive and negative electrodes of the unassembled lithium battery are installed on the lithium battery body through pressing. The external main shaft 14 is used to realize the external movement of the whole device. When the induction piece 15 and the proximity switch I 16 approach each other, the pneumatic telescopic cylinder 13 is controlled to stop moving;

[0041] Lithium battery handling steps: The assembled lithium battery 3 is placed on the transportation line. The photoelectric sensor 4 detects whether the clamping jaw 24 has moved to the designated position. After arrival, the photoelectric sensor 4 controls the pneumatic telescopic cylinder 13 to stop moving downward. The pneumatic finger 23 controls the clamping jaw 24 to clamp and transport the lithium battery 3. Among them, the buffer pad I 26 is used to prevent damage to the lithium battery 3 during the clamping process, and the buffer pad II 27 is used to prevent the lithium battery electrode from contacting the clamping jaw 24 and causing a safety accident.
