Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, specifically a positioning tooling for battery current collector production. Background Technology

[0002] A battery current collector, as the name suggests, refers to a structure or component that collects current. In lithium-ion batteries, this mainly refers to metal foil, such as copper foil or aluminum foil. More broadly, it can also include the electrode tabs. Its main function is to collect the current generated by the battery's active materials to form a larger current output.

[0003] According to a publicly disclosed positioning fixture for battery current collector production (Announcement No.: CN219170849U), the above application sets two first guide rails on the top surface of the workbench. In actual operation, by rotating the first threaded rod, the two first moving plates can move horizontally in opposite directions along the first guide rails. With the rotation of the third threaded rod, the upper clamping plate can be raised and lowered, and the current collector can be initially fixed. The four side fixing columns on both sides of the workbench can effectively prevent the current collector from sliding, thereby ensuring the positioning accuracy. The current collector can be positioned by using the fixing box in conjunction with the four side fixing columns.

[0004] However, in actual use, when processing the same type of template current collector, the current collector is mostly metal foil, which is relatively soft. When workers move the clamping plates with many bolts to hold and position the metal foil, the clamping force is too large, which can easily cause deformation of the current collector surface and affect the subsequent use of the battery current collector. In view of this, we propose a positioning fixture for battery current collector production. Utility Model Content

[0005] The purpose of this invention is to provide a positioning fixture for battery current collector production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for battery current collector production, comprising a support platform, a support block disposed on the outer side of the support platform, a motor fixedly mounted on the surface of the support block, a lead screw fixedly connected to the output end of the motor, a support frame threadedly connected to the surface of the lead screw, a positioning mechanism disposed on the surface of the support platform, and a promoting mechanism disposed on the surface of the support platform, the positioning mechanism comprising:

[0007] A straight rod is fixedly installed on the inner wall of the support frame. A sleeve is sleeved on the surface of the straight rod. A torsion spring is fixedly connected to the arc surface of the sleeve. The end of the torsion spring away from the arc surface of the sleeve is fixedly connected to the inner wall of the clamping plate.

[0008] A reset spring is provided, with one end of the reset spring fixedly connected to the inner wall of the clamping plate and the other end of the reset spring fixedly connected to a round rod. A mounting plate is fixedly installed on the lower surface of the round rod, and a rubber plate is fixedly installed on the lower surface of the mounting plate. A through hole is provided inside the rubber plate, and a protrusion is fixedly installed on the surface of the rubber plate.

[0009] Preferably, the promoting mechanism includes a fixing block, which is fixedly installed on the inner wall of the support frame. A telescopic spring is fixedly connected to the upper surface of the fixing block. A control plate is fixedly connected to the end of the telescopic spring away from the fixing block. A control disk is fixedly installed on the side wall of the sleeve, and a gear is fixedly installed on the side wall of the control disk.

[0010] Preferably, the surface of the fixing block is provided with a sliding groove, the diameter of which is adapted to the diameter of the middle part of the control plate, and the lower end of the control plate is provided with an arc plate with teeth that mesh with gears.

[0011] Preferably, the surface of the clamping plate is provided with a rotating groove, the diameter of which is adapted to the diameter of the sleeve, and the clamping plate is sleeved on the surface of the sleeve.

[0012] Preferably, the side wall of the clamping plate has a movable hole, the diameter of which is adapted to the diameter of the round rod.

[0013] Preferably, the through holes are triangular in shape, and there are several through holes arranged in a linear array and staggered inside the rubber sheet.

[0014] Compared with the prior art, this utility model provides a positioning fixture for battery current collector production, which has the following advantages:

[0015] 1. This positioning fixture for battery current collector production features a positioning mechanism. A motor drives a lead screw to rotate, causing the support frames at both ends to move towards the center. One end of the clamping plate is attached to the support platform, allowing the clamping plate to rotate around the sleeve. The L-shaped clamping plate clamps the upper surface of the current collector while simultaneously centering and limiting the sidewall edge. Under the action of a round rod and a return spring, the rubber plate on the mounting plate stably fixes the surface of the current collector. The rubber plate has through holes inside to facilitate better compression of the current collector surface. The protrusions increase friction on the current collector surface, ensuring the stability of the current collector and providing protective positioning for the soft current collector, facilitating subsequent processing.

[0016] 2. This positioning fixture for battery current collector production is equipped with a facilitating mechanism. Pulling the control plate releases the gear limit, and rotating the control disc causes the sleeve to rotate. The initial value of the torsion spring's deformation is adjusted to facilitate the adjustment of the pressure of the upper surface of the clamping plate on the current collector surface. Releasing the control plate's extension spring ensures that the teeth on the control plate mesh with the gear, ensuring the stability of the sleeve, and thus providing protective fixation for the current collector surface.

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: a positioning fixture for battery current collector production, including a support platform 1, a support block 7 on the outside of the support platform 1, a motor 6 fixedly mounted on the surface of the support block 7, a lead screw 2 fixedly connected to the output end of the motor 6, a support frame 5 threadedly connected to the surface of the lead screw 2, a positioning mechanism 3 on the surface of the support platform 1, and a promoting mechanism 4 on the surface of the support platform 1. The positioning mechanism 3 includes a straight rod 301, a sleeve 302, a torsion spring 303, a clamping plate 304, a return spring 305, a round rod 306, a mounting plate 307, a rubber plate 308, a through hole 309, and a protrusion 310.

[0025] In one embodiment of this utility model, a straight rod 301 is fixedly installed on the inner wall of the support frame 5. A sleeve 302 is sleeved on the surface of the straight rod 301. A torsion spring 303 is fixedly connected to the arc surface of the sleeve 302. One end of the torsion spring 303 away from the arc surface of the sleeve 302 is fixedly connected to the inner wall of the clamping plate 304. One end of the return spring 305 is fixedly connected to the inner wall of the clamping plate 304. The other end of the return spring 305 is fixedly connected to a round rod 306. An mounting plate 307 is fixedly installed on the lower surface of the round rod 306. A rubber plate 308 is fixedly installed on the lower surface of the mounting plate 307. A through hole 309 is opened inside the rubber plate 308. A protrusion 310 is fixedly installed on the surface of the rubber plate 308.

[0026] In addition, the promoting mechanism 4 includes a fixing block 401, which is fixedly installed on the inner wall of the support frame 5. A telescopic spring 403 is fixedly connected to the upper surface of the fixing block 401. The end of the telescopic spring 403 away from the fixing block 401 is fixedly connected to the control plate 402. A control disk 405 is fixedly installed on the side wall of the sleeve 302. A gear 404 is fixedly installed on the side wall of the control disk 405. A groove is opened on the surface of the fixing block 401. The diameter of the groove is adapted to the diameter of the middle part of the control plate 402. An arc plate is provided at the lower end of the control plate 402. Teeth are provided on the arc plate and mesh with the gear 404.

[0027] In this embodiment of the utility model, a rotating groove is provided on the surface of the clamping plate 304, the diameter of which is adapted to the diameter of the sleeve 302. The clamping plate 304 is sleeved on the surface of the sleeve 302. A movable hole is provided on the side wall of the clamping plate 304, the diameter of which is adapted to the diameter of the round rod 306. The through hole 309 is triangular in shape and there are several through holes 309. Several through holes 309 are arranged in a linear array and staggered inside the rubber plate 308, which facilitates the rubber plate 308 to compress the upper surface of the collector and deform it to protect the upper surface of the collector. Several protrusions 310 are arranged in a linear array and fixedly installed on the lower surface of the rubber plate 308 to increase the friction between the rubber plate 308 and the surface of the collector and prevent the collector from sliding during processing.

[0028] In this utility model, during use, the motor 6 drives the lead screw 2 to rotate, causing the support frames 5 at both ends to move towards the center. One end of the clamping plate 304 is attached to the support platform 1, causing the clamping plate 304 to rotate around the sleeve 302. The clamping plate 304 is L-shaped to clamp the upper surface of the collector while centering and limiting the edge of the side wall. Under the action of the round rod 306 and the return spring 305, the rubber plate 308 on the mounting plate 307 stably fixes the surface of the collector. The rubber plate 308 has a through hole 309 inside, which facilitates better compression of the surface of the collector. The protrusion 310 increases the friction on the surface of the collector, ensuring the stability of the collector and providing protective positioning for the soft collector, which is convenient for subsequent processing.

[0029] Furthermore, by pulling the control plate 402, the limit on the gear 404 is released. The sleeve 302 is rotated by rotating the control disk 405, and the initial value of the deformation of the torsion spring 303 is adjusted to facilitate the adjustment of the pressure of the upper surface of the clamping plate 304 on the surface of the collector. The extension spring 403 of the control plate 402 is released to ensure that the teeth on the control plate 402 mesh with the gear 404, ensuring the stability of the sleeve 302, and thus providing protective fixation for the surface of the collector.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
