Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a grasping device for a cylindrical battery. Background Art

[0002] In the manufacturing process of large cylindrical batteries, each process involves battery clamping, placement and transportation. At present, battery clamping is basically done by the action of the clamping claw cylinder, which drives the clamping claw to clamp the battery. Since the cylinder is affected by the air pressure, the wear and fall of the rubber material on the clamping claw, etc., the battery shell will be damaged to varying degrees during the clamping process, affecting the appearance quality of the battery.

[0003] In addition, since each battery requires a cylinder and a gripper, a steel plate is required to fix the cylinder, which makes the entire gripper module very heavy and reduces the moving speed, which increases the load capacity of the module and the robot, increases the equipment cost, and reduces the equipment efficiency; it also reduces the compatibility of the cylinder gripper, requires more parts to be replaced, and prolongs the changeover time and cost; Utility Model Content

[0004] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is: how to provide a gripping device with a simple structure, light weight, which is conducive to reducing equipment costs and ensuring the appearance quality of the battery.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A gripping device for cylindrical batteries, comprising a clamping claw base, one side of which is provided with a clamping mechanism, characterized in that the clamping mechanism comprises a plurality of clamping claws evenly distributed along a ring, the clamping claws extending along the ring axis in a strip shape, and a retractable clamping claw airbag on the side facing the center of the ring; the clamping claw base is provided with an airway module connected to the plurality of clamping claw airbags, and the airway module is provided with an air inlet for connecting to an air source.

[0007] In this way, the jaws are arranged in a ring shape, and a jaw airbag is set on the inner side. When grasping, the clamping mechanism is aligned with the battery, and the battery is placed between multiple jaws. The multiple jaw airbags are ventilated at the same time through the airway module, so that the jaw airbags expand toward the middle and squeeze on the surface of the cylindrical battery. Since the jaw airbag has good flexibility, it will not damage the battery surface, which is beneficial to ensure the appearance quality of the battery. At the same time, compared with mechanical jaws, the jaw airbag is lighter, has a lower load, and is more agile, which is beneficial to improve work efficiency and reduce equipment costs. In addition, since the jaw airbag is adaptable, it has good compatibility with cylindrical batteries of different diameters, which can save changeover time and cost in the production process.

[0008] Furthermore, the airway module includes a main airbag in a circular shape, and a pressure gauge is connected to the main airbag; the clamping claw airbag is connected to the main airbag.

[0009] Furthermore, the outer side of the clamping jaw airbag has a supporting rib extending along the length direction, and one end of the supporting rib is connected to the clamping jaw base.

[0010] In this way, during the air intake and exhaust process, only the inner side of the gripper airbag will shrink.

[0011] Furthermore, an auxiliary air bag is arranged on the outer side of the support rib, and the auxiliary air bag is connected between the support rib and the clamping jaw base, so that the end of the support rib away from the clamping jaw base can swing along the annular radial direction.

[0012] In this way, the position of the end of the supporting rib is changed by the auxiliary airbag, so that it can adapt to cylindrical batteries with different diameters.

[0013] Furthermore, the inner side of the clamping jaw airbag has a transversely arranged convex ridge, and a plurality of the convex ridges are evenly distributed along the length direction of the clamping jaw airbag.

[0014] In this way, the friction between the gripper airbag and the cylindrical battery can be increased by the convex ridges, thereby making it possible to grasp the battery more stably and reliably.

[0015] Furthermore, the clamping claw airbag has shrinkage folds on both side surfaces in the circumferential direction of the clamping mechanism.

[0016] Furthermore, the inner side of the clamping jaw airbag has a flexibly bendable strip, and the strip is arranged along the length direction of the clamping jaw airbag; the convex ridge is arranged at one end of the strip away from the clamping jaw base.

[0017] In this way, the wear resistance of the clamping jaws can be increased by the strips, thereby extending the service life of the clamping jaws.

[0018] Furthermore, the clamping jaw airbag, supporting ribs, convex edges and strips are integrally injection molded.

[0019] Furthermore, the gripper airbag is made of corrosion-resistant and wear-resistant colloid material.

[0020] Furthermore, a suction cup is provided on the clamping jaw base, and the suction cup is located at the center of the plurality of clamping jaw airbags.

[0021] In this way, the suction cup can assist the grasping of the cylindrical battery, thereby increasing the reliability of the grasping. In addition, the suction force of the suction cup can also be used to determine whether the battery has been grasped.

[0022] In summary, the utility model has the advantages of simple structure, light weight, being beneficial to reducing equipment cost, and ensuring the appearance quality of the battery. BRIEF DESCRIPTION OF THE DRAWINGS
