Description

Technical Field

[0001] This utility model relates to the field of lithium battery core technology, specifically a lithium battery core hole enlargement device. Background Technology

[0002] Lithium-ion battery cores are an important battery component, widely used in mobile electronic devices, electric vehicles, and energy storage systems. They are formed by stacking positive electrode sheets, negative electrode sheets, and separators in a certain order. To increase the electrolyte permeability between the positive and negative electrodes and improve the power performance and cycle life of the battery, lithium-ion battery cores are usually subjected to a hole-enlarging process.

[0003] For example, in the patent with publication number CN221262472U, the lithium battery core to be enlarged is inserted into the clamping seat, and the first motor drives the bidirectional lead screw to rotate. The two threaded blocks connected by two threads drive the two lower clamping blocks to move closer to each other. At the same time, the connecting block drives the two upper clamping blocks to move synchronously, so as to achieve multi-directional synchronous clamping and fixing, thereby clamping and fixing lithium battery cores of different diameters.

[0004] However, when using the bidirectional lead screw in this structure, the two threaded blocks may become asynchronous due to pitch error, assembly accuracy, and the difference in friction between the two threaded blocks and the guide rail. If the core is pushed to the side with greater friction, the center position cannot be guaranteed, and the core purpose of synchronous clamping is lost. Furthermore, the clamping blocks are in direct contact with the battery cell. If the material of the clamping blocks is too hard or has impurities on the surface, it will scratch the outer membrane of the battery cell. Therefore, a lithium battery core enlargement device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a lithium battery core enlargement device to solve at least one technical problem existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lithium battery core enlarging device, comprising:

[0008] A base, the top of which is provided with a clamping seat, and the surface of the clamping seat is provided with a clamping mechanism and a suction mechanism;

[0010] The three sliding rods in motion are used to drive the three clamping plates and silicone pads to move synchronously, and the three clamping plates and silicone pads in close proximity in motion are used to center-position and clamp the lithium battery core. The silicone pads are used to prevent the clamping plates from clamping the lithium battery core too hard.

[0011] The suction mechanism is used to clean impurities from the surfaces of the clamping plate and the silicone pad.

[0021] Preferably, the surface of the collection box is formed with multiple suction holes, and the vacuum cleaner, when powered on, is used to provide suction to the interior of the collection box.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. By setting up a clamping mechanism, the three slide rods can move synchronously in a straight line along the radial direction of the ring frame under the rotation of the turntable, avoiding the traditional two-way screw structure and eliminating the asynchronous problem caused by pitch error, assembly error or uneven friction. When the three slide rods move synchronously towards the center, they push the three clamping plates and silicone pads to move closer together, thereby uniformly clamping the lithium battery core located in the center from three directions, thus achieving the center positioning and clamping of the lithium battery core.

[0024] 2. By setting up a suction mechanism, the hydraulic cylinder drives the collection box to move towards the center area of ​​the clamping seat. Then, the vacuum cleaner drives the collection box to suck the dust, metal shavings and other impurities on the surface of the clamping plate and silicone pad into the collection box by airflow. This automatically cleans the impurities on the clamping surface before clamping, avoiding damage to the outer membrane of the battery cell. Attached Figure Description

[0034] Please see Figures 1-4 An embodiment of a lithium battery core enlarging device provided by this utility model:

[0035] A lithium battery core enlarging device, comprising:

[0036] The base 1 has a clamping seat 2 on its top, and the surface of the clamping seat 2 is provided with a clamping mechanism 3 and a suction mechanism 4.

[0037] The clamping mechanism 3 includes three clamping plates 301, a slide bar 308, and a silicone pad 3010;

[0038] The three sliding rods 308 in motion are used to drive the three clamping plates 301 and the silicone pad 3010 to move synchronously, and the three clamping plates 301 and the silicone pad 3010 in close proximity in motion are used to center-position and clamp the lithium battery core. The silicone pad 3010 is used to prevent the clamping plates 301 from clamping the lithium battery core too hard.

[0039] The suction mechanism 4 is used to clean impurities from the surfaces of the clamping plate 301 and the silicone pad 3010;

[0040] The clamping mechanism 3 also includes a toothed ring 302, a ring frame 303, a gear 304, a turntable 305, a motor 309, and three strip grooves 306 and arc grooves 307;

[0041] The ring frame 303 is rotatably connected to the inner side of the clamping seat 2, the turntable 305 is rotatably connected to the outer side of the clamping seat 2, the gear ring 302 is fixedly assembled to the outer side of the turntable 305, the strip groove 306 is opened on the surface of the ring frame 303, the arc groove 307 is opened on the surface of the turntable 305, the motor 309 is fixedly installed on the outer side of the clamping seat 2, and the gear 304 is fixedly assembled to the end of the output shaft of the motor 309.

[0042] Gear 304 meshes with gear ring 302, and gear 304 and gear ring 302 in the meshing state are used to drive turntable 305 to rotate. The above structural design enables the output shaft of motor 309 in the running state to drive gear 304 to start rotating. Since gear 304 meshes with gear ring 302, gear 304 in the rotating state drives turntable 305 to rotate on clamping seat 2 through gear ring 302.

[0043] The slide rod 308 is slidably connected to the strip groove 306 and the arc groove 307, and the slide rod 308 moves along the inner wall trajectory of the strip groove 306 and the arc groove 307. The above structural design makes it possible for the arc groove 307 on the turntable 305 to push the slide rod 308 to move when the turntable 305 rotates. Since the other end of the slide rod 308 is also restricted in the radial strip groove 306 of the ring frame 303, the movement trajectory of the slide rod 308 is the result of the joint constraint of the arc groove 307 of the turntable 305 and the strip groove 306 of the ring frame 303.

[0044] The clamping plate 301 is fixedly connected to one side of the slide bar 308, and the silicone pad 3010 is fixedly connected to one side of the clamping plate 301. The above structural design allows the soft material of the silicone pad 3010 to provide cushioning, preventing the clamping plate 301 from directly and rigidly contacting the battery cell, and preventing excessive clamping force from damaging the core.

[0045] In one preferred embodiment, the rotating turntable 305 is used to drive the three slide rods 308 to move synchronously. The above structural design ensures that the three slide rods 308 can move synchronously in a straight line along the radial direction of the ring frame 303 under the rotation of the turntable 305.

[0046] In one preferred embodiment, the suction mechanism 4 includes a hydraulic cylinder 401, a mounting bracket 402, a collection box 403, and a vacuum cleaner 404;

[0047] Hydraulic cylinder 401 is fixedly installed on one side of base 1, mounting bracket 402 is fixedly connected to the output end of hydraulic cylinder 401, collection box 403 is detachably connected to one side of mounting bracket 402 by bolts, and vacuum cleaner 404 is fixedly installed on the inner wall of collection box 403. The above structural design allows hydraulic cylinder 401 to be started, causing the output end of hydraulic cylinder 401 in operation to push mounting bracket 402 and collection box 403 to move towards the center area of ​​clamping seat 2 (i.e., the position where the core is usually placed), and then vacuum cleaner 404 to be started, generating strong suction through its operation. This suction forms a directional airflow through the suction holes on the surface of collection box 403, and the collection box 403 sucks dust, metal shavings and other impurities on the surface of clamping plate 301 and silicone pad 3010 into the collection box 403 by the airflow.

[0048] In one preferred embodiment, the output end of the energized hydraulic cylinder 401 is used to drive the collection box 403 to move to the central clamping area of ​​the clamping seat 2. The above structural design enables the output end of the hydraulic cylinder 401 in operation to push the mounting frame 402 and the collection box 403 to move towards the central area of ​​the clamping seat 2.

[0049] In one preferred embodiment, the surface of the collection box 403 is formed with a plurality of suction holes, and the vacuum cleaner 404, when powered on, is used to provide suction to the interior of the collection box 403. The above structural design allows the suction generated by the vacuum cleaner 404 to form a directional airflow through the suction holes on the surface of the collection box 403, so that the dust, metal shavings and other impurities on the surface of the clamping plate 301 and the silicone pad 3010 are sucked into the collection box 403 by the airflow.

[0050] The working principle of this utility model is as follows: First, the motor 309 is started, and the output shaft of the running motor 309 drives the gear 304 to start rotating. Since the gear 304 meshes with the gear ring 302, the rotating gear 304 drives the turntable 305 to rotate on the clamping seat 2 through the gear ring 302. When the turntable 305 rotates, the arc groove 307 on it will push the slide rod 308 to move. Since the other end of the slide rod 308 is also restricted in the radial strip groove 306 of the ring frame 303, the movement trajectory of the slide rod 308 is the result of the joint constraint of the arc groove 307 of the turntable 305 and the strip groove 306 of the ring frame 303. Thus, the double groove constraint structure ensures that the three slide rods 308 can move synchronously in a straight line along the radial direction of the ring frame 303 under the rotation of the turntable 305, avoiding the traditional two-way screw structure and eliminating the asynchronous problem caused by pitch error, assembly error or uneven friction.

[0051] When the three slide bars 308 move towards the center in sync, they push the three clamping plates 301 and the silicone pad 3010 to move closer together, thereby evenly gripping the lithium battery core located in the center from three directions. The soft material of the silicone pad 3010 provides cushioning, preventing the clamping plates 301 from directly and rigidly contacting the battery core and preventing excessive clamping force from damaging the core.

[0052] When it is necessary to clean the clamping plate 301 and silicone pad 3010, firstly, the hydraulic cylinder 401 is started, so that the output end of the running hydraulic cylinder 401 pushes the mounting bracket 402 and the collection box 403 to move towards the center area of ​​the clamping seat 2 (i.e., the position where the core is usually placed). Then, the vacuum cleaner 404 is started, and its operation generates a strong suction force. This suction force forms a directional airflow through the suction holes on the surface of the collection box 403. The collection box 403 then sucks in the dust, metal shavings and other impurities on the surface of the clamping plate 301 and silicone pad 3010. After cleaning is completed, the output end of the hydraulic cylinder 401 retracts, moving the collection box 403 out of the working area, preparing for the next step of inserting the lithium battery core for hole enlargement. The collection box 403 is connected to the mounting bracket 402 by bolts, which facilitates regular disassembly for cleaning and maintenance.

[0053] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
