Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to a guiding and supporting device for gripping battery casings. Background Technology

[0002] The lithium battery casing is cylindrical with one end completely open, placed face down in the finished product basket. After molding, the battery casing needs to be transferred from the finished product basket of the previous process to the cleaning basket of the next process, and then placed together with the cleaning basket into the cleaning machine for cleaning. Because the battery casings in the finished product basket are not neatly arranged, accurately grasping the battery casings becomes a major challenge in achieving automated battery casing grasping. Summary of the Invention

[0003] To address the technical problem that existing technologies cannot automate the precise gripping of battery casings, this application proposes a guiding and supporting device for gripping battery casings, which solves the aforementioned technical problem.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] This utility model provides a guiding and supporting device for gripping battery casings, comprising: a lifting module, the lifting module including a lifting plate capable of lifting, a vertical hollow rod disposed on the lifting plate, the hollow rod being clearance-fitted with the lifting plate, the end of the hollow rod away from the lifting plate forming an insertion end, the insertion end being disposed of a suction cup, the suction cup entering the battery casing along with the insertion end to adsorb the battery casing; and a gripping module, the gripping module including two clamping claws that can close and open, the clamping claws being used to engage the battery casing lifted by the lifting module, the engagement end of the clamping claws forming a tapered guide surface that gradually narrows from the outer circle to the inner circle.

[0006] Furthermore, the lifting plate is provided with an assembly hole, and a linear bearing is disposed in the assembly hole, and the hollow rod body is slidably engaged with the linear bearing.

[0007] Furthermore, the linear bearing has a receiving cylinder and a mounting plate disposed at one end of the receiving cylinder. After the receiving cylinder is inserted into the assembly hole, the mounting plate abuts against the lower bottom surface of the lifting plate, and the mounting plate is detachably connected to the lifting plate.

[0008] Furthermore, the end of the hollow rod away from the insertion end is formed as a vent end, and an air connector is installed at the vent end to connect to an external air pipe.

[0009] Furthermore, the lifting module also includes a buffer assembly, which includes an elastic element and a snap-fit ​​element. The snap-fit ​​element is snapped onto the hollow rod and is located on the portion of the hollow rod that protrudes from the top surface of the lifting plate. The elastic element is sleeved on the hollow rod, with one end abutting against the top surface of the lifting plate and the other end abutting against the snap-fit ​​element, so that the hollow rod can retract and compress the elastic element, thereby mitigating the impact force of the battery casing on the hollow rod hitting the gripper.

[0010] Furthermore, the lower end face of the gripper is formed as the access end, and the gripper is formed sequentially from bottom to top from the access end as a guide section, a clamping section and a connecting section. The guide section is formed with the tapered guide surface, the clamping section is clamped on the outer wall surface of the battery casing, and the connecting section is connected to the drive assembly of the gripper.

[0011] Furthermore, the lifting plate of the lifting module is equipped with a plurality of hollow rods; correspondingly, the gripping module includes a liftable connecting plate, and the connecting plate is equipped with a plurality of grippers corresponding to the positions of the suction cups on the hollow rods.

[0012] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0013] This utility model discloses a guiding and supporting device for gripping battery casings. A hollow rod, fitted with a gap on a lifting plate, engages with a tapered guide surface at the access end of the gripper. This achieves guiding and supporting during battery casing gripping. Specifically, after the suction cup on the hollow rod picks up the battery casing, the lifting plate raises the battery casing to the access end of the gripper. The end of the battery casing held by the suction cup rests against the tapered guide surface. At this time, the hollow rod will sway at the gap in its engagement with the lifting plate, causing the battery casing to move horizontally along the tapered guide surface, thus adaptively correcting itself. This allows the gripper to achieve automation while accurately gripping the battery casing. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] like Figure 1-9As shown, this utility model provides a guiding and supporting device for gripping battery casings, including a lifting module 1 and a gripping module 2. The lifting module 1 includes a lifting plate 11 capable of lifting, and a vertical hollow rod 12 is disposed on the lifting plate 11. The hollow rod 12 is clearance-fitted with the lifting plate 11, and the end of the hollow rod 12 away from the lifting plate 11 is formed as an insertion end. A suction cup 13 is disposed on the insertion end. The suction cup 13 enters into the battery casing a along with the insertion end to adsorb the battery casing a. The gripping module 2 includes two clamps 21 that can close and open. The clamps 21 are used to access the battery casing a lifted by the lifting module 1. The access end of the clamps 21 has a tapered guide surface 22 that gradually narrows from the outer circle to the inner circle to guide and support the lifted battery casing a.

[0029] In one specific embodiment of this utility model, the lifting plate 11 is provided with an assembly hole, and a linear bearing 14 is disposed in the assembly hole. The rod body of the hollow rod 12 is slidably engaged with the linear bearing 14. The sliding engagement method ensures the clearance for the hollow rod 12 to swing.

[0030] Furthermore, the linear bearing 14 has a receiving cylinder 141 and a mounting piece 142 disposed at one end of the receiving cylinder 141. After the receiving cylinder 141 is inserted into the assembly hole, the mounting piece 142 abuts against the lower bottom surface of the lifting plate 11, and the mounting piece 142 is detachably connected to the lifting plate 11. The mounting piece 142 can be screwed to the lifting plate 11.

[0031] Furthermore, the end of the hollow rod 12 away from the insertion end is formed as a venting end, and an air connector 15 is installed at the venting end to connect to an external air pipe. Preferably, the air connector 15 is fixedly connected to the hollow rod 12 and abuts against the lower surface of the lifting plate 11 where the linear bearing 14 is located as the hollow rod 12 moves.

[0032] In a preferred embodiment of this utility model, the lifting module 1 further includes a buffer assembly 16, which includes an elastic element 161 and a snap-fit ​​element 162. The snap-fit ​​element 162 is snapped onto the body of the hollow rod 12 and is located at the portion of the hollow rod 12 that protrudes from the top surface of the lifting plate 11. The elastic element 161 is sleeved on the body of the hollow rod 12, with one end of the elastic element 161 abutting against the top surface of the lifting plate 11 and the other end of the elastic element 161 abutting against the snap-fit ​​element 162, so that the hollow rod 12 can retract and compress the elastic element 161, thereby relieving the impact force of the battery housing a hitting the gripper 21 on the hollow rod 12, and also facilitating the guidance and support of the battery housing a. Specifically, the snap-fit ​​element 162 is a snap-fit ​​spring, which is detachably connected to the hollow rod 12 through a snap-fit ​​groove on the outer wall of the hollow rod 12; the elastic element 161 is preferably a spring. Under the action of the spring, the part of the hollow rod 12 protruding from the lifting plate 11 is in its longest state, such as when the gas connector 15 is already against the bottom surface of the lifting plate 11. At this time, pressing the inserted end of the hollow rod 12 causes the hollow rod 12 to act on the spring through the snap-fit ​​spring, compressing the spring and causing the hollow rod 12 to retract relative to the lifting plate 11, thus relieving the impact force of the hollow rod 12 moving upward, that is, relieving the impact force of the battery casing a hitting the gripper 21.

[0033] In a specific embodiment of this utility model, the lower end face of the gripper 21 is formed as an access end. The gripper 21 is formed from bottom to top with a guide section 23, a clamping section 24 and a connecting section 25. A tapered guide surface 22 is formed on the guide section 23. The clamping section 24 is clamped on the outer wall of the battery housing a. The connecting section 25 is connected to the drive assembly of the gripper 21. The drive assembly can be selected as a drive cylinder that drives the two grippers 21 to achieve the closing and opening action.

[0034] In a preferred embodiment of this invention, the lifting plate 11 of the lifting module 1 is equipped with a plurality of hollow rods 12; correspondingly, the gripping module 2 includes a liftable connecting plate 26, on which a plurality of grippers 21 are configured corresponding to the positions of the suction cups 13 on the hollow rods 12. The guiding and supporting device for gripping battery casings of this invention has a simple and compact structure, and multiple devices can be assembled on the same lifting mechanism, thereby greatly improving automation efficiency.

[0035] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
