Description

Technical Field

[0001] This utility model relates to the field of battery production, and in particular to a positioning mechanism for polymer cell production. Background Technology

[0002] Battery cells are the core components of batteries. Their production involves materials science, precision manufacturing, and strict quality control, which directly affects the performance, safety, and lifespan of batteries. After preparation and assembly, battery cells need to be tested. The battery cells to be tested are in a packaged state, with a relatively large protective layer on the outside. The transportation and testing station needs to use positioning devices to position the battery cell package.

[0003] A search of existing technologies revealed a "cell positioning and shaping fixture for a battery cell production line," with publication number "CN221994520U." This device can be installed on a battery cell production line, allowing the battery cell positioning and shaping fixture 1 to position and shape the battery cells flowing on the production line, thus precisely controlling the position of the battery cells on the production line. However, when a transfer operation is required, the end of the battery cell package retains an uncut protective layer, which can easily cause the battery cells to tilt during placement, resulting in deviations in the measured values ​​and affecting the accuracy of the detection.

[0004] Therefore, a positioning mechanism for polymer battery cell production is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a positioning mechanism for polymer battery cell production to solve the above-mentioned problems. This mechanism improves the problem that the protective layer left at the end of the battery cell pack is not sheared, which can easily cause the battery cell to tilt during placement, resulting in deviations in the measured values ​​and affecting the accuracy of the test.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a positioning mechanism for polymer battery cell production, comprising: a separator frame, wherein multiple connecting partitions are fixedly connected to both sides of the separator frame, and the multiple connecting partitions are evenly distributed in a straight line along the side of the separator frame; a positioning device, wherein the positioning device is installed on the outside of the separator frame; wherein the positioning device includes a connecting component installed on the surface of the separator frame, and a positioning component is provided on the side of the connecting component away from the adjacent connecting partition, the surface of the positioning component extending into the interior of the connecting component, and a locking component is provided on the side of the positioning component away from the connecting component, the surface of the locking component extending into the interior of the connecting component; wherein the connecting component includes a fixed bracket, the separator frame is fixedly connected to the inner bottom wall of the fixed bracket, the lower end of the connecting partition is fixedly connected to the inner bottom wall of the fixed bracket, and the lower end of the fixed bracket is provided with multiple bottom slides, the bottom slides being located between adjacent connecting partitions.

[0007] Preferably, the positioning component includes a movable bracket, with sealing plates fixedly connected to both ends of the movable bracket. Multiple fixed partitions are disposed between the two sealing plates, and the fixed partitions are fixedly connected to the inner wall of the movable bracket. A base plate is fixedly connected to the lower end of the movable bracket, and a vertical slide is fixedly connected to the upper end of the base plate. When the movable bracket is moved closer to the fixed bracket, the abutment strip is inserted between the adjacent connecting partitions.

[0008] Preferably, the locking assembly includes a circular tube embedded in the surface of the movable bracket away from the connecting assembly. A rotating shaft is rotatably connected to the inner wall of the circular tube. Connecting rods are fixedly connected to both ends of the rotating shaft, and a locking buckle is fixedly connected to the other end of each connecting rod. Moving the connecting rod causes the locking buckle to enter the interior of the straight slide rail.

[0009] Preferably, the fixed bracket has a straight slide rail and a buckle groove on both sides, the straight slide rail is horizontally set, and the longitudinal section of the buckle groove is arc-shaped.

[0010] Preferably, the locking buckle extends into the interior of the adjacent buckle groove near the surface of the connecting partition, and the surface of the locking buckle contacts the inner wall of the adjacent buckle groove. The locking buckle moves in an arc along the inner wall of the buckle groove, thereby ensuring a tight connection between the fixed bracket and the movable bracket through the locking buckle and the connecting rod, preventing easy separation.

[0011] Preferably, the vertical slide is slidably connected to the inner wall of the adjacent bottom slide, and an abutment strip is fixedly connected to the upper end of the vertical slide. The vertical slide slides synchronously on the inner wall of the bottom slide to place the completed battery cell.

[0012] Preferably, the abutment strip is located between adjacent fixed partitions, and the lower end of the abutment strip is slidably connected to the inner bottom wall of the fixed bracket. The abutment strip extends into the space at the bottom of the battery pack, assisting in adjusting the bottom edge of the battery pack and reducing the occurrence of bending at the bottom of the battery pack.

[0013] The beneficial effects of this utility model are:

[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-4 As shown, a positioning mechanism for polymer battery cell production includes: a separator 1, with multiple connecting partitions 2 fixedly connected to both sides of the separator 1, the multiple connecting partitions 2 being evenly distributed in a straight line along the side of the separator 1; and a positioning device 3, which is installed on the outside of the separator 1. The positioning device 3 includes a connecting component 33 installed on the surface of the separator 1, a positioning component 31 provided on the side of the connecting component 33 away from the adjacent connecting partition 2, the surface of the positioning component 31 extending into the interior of the connecting component 33, and a locking component 32 provided on the side of the positioning component 31 away from the connecting component 33, the surface of the locking component 32 extending into the interior of the connecting component 33.

[0023] The connecting component 33 includes a fixed bracket 331, a partition 1 fixedly connected to the inner bottom wall of the fixed bracket 331, and the lower end of the connecting partition 2 fixedly connected to the inner bottom wall of the fixed bracket 331. The lower end of the fixed bracket 331 is provided with multiple bottom slides 332, which are located between adjacent connecting partitions 2. Both sides of the fixed bracket 331 are provided with straight slides 333 and buckles 334. The straight slides 333 are horizontally arranged, and the longitudinal section of the buckles 334 is arc-shaped.

[0024] like Figures 1-4 As shown, the positioning component 31 includes a movable bracket 311. Both ends of the movable bracket 311 are fixedly connected to a sealing plate 313. A plurality of fixed partitions 312 are provided between the two sealing plates 313. The fixed partitions 312 are fixedly connected to the inner wall of the movable bracket 311. The lower end of the movable bracket 311 is fixedly connected to a base plate 314. The upper end of the base plate 314 is fixedly connected to a vertical slide 315. The vertical slide 315 is slidably connected to the inner wall of an adjacent bottom slide 332. The upper end of the vertical slide 315 is fixedly connected to an abutment strip 316. The abutment strip 316 is located between adjacent fixed partitions 312. The lower end of the abutment strip 316 is slidably connected to the inner bottom wall of the fixed bracket 331.

[0025] When the device is in use, the connecting partition 2 can separate the battery cell to be tested. At the same time, the device can position multiple battery cells by combining the connecting partition 2 and the fixed partition 312. When inserting the battery cell, it can be inserted through the side of the separator 1 near the connecting partition 2, which makes the battery cell insertion more convenient and reduces the occurrence of bending at the bottom of the battery cell.

[0026] After the battery cell is inserted, the movable bracket 311 can be moved closer to the fixed bracket 331, so that the contact strip 316 is inserted between the adjacent connecting partitions 2. At the same time, the vertical slide 315 slides synchronously on the inner wall of the bottom slide 332. The placed battery cell can be positioned as a whole by the connecting partitions 2 and the fixed partitions 312. The contact strip 316 extends into the space at the bottom of the battery cell pack to assist in adjusting the bottom edge of the battery cell pack and reduce the occurrence of bending at the bottom of the battery cell pack.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, the locking assembly 32 includes a circular tube 321 embedded in the surface of the movable bracket 311 away from the connecting assembly 33. The inner wall of the circular tube 321 is rotatably connected to a rotating shaft 322. Both ends of the rotating shaft 322 are fixedly connected to a connecting rod 323. The other end of the connecting rod 323 is fixedly connected to a locking buckle 324. The locking buckle 324 extends into the interior of the adjacent buckle groove 334 near the surface of the connecting partition 2. The surface of the locking buckle 324 contacts the inner wall of the adjacent buckle groove 334.

[0028] After the movable bracket 311 and the fixed bracket 331 are combined, the device can be moved by the connecting rod 323 to allow the locking buckle 324 to enter the interior of the straight slide rail 333. When the movable bracket 311 contacts the fixed bracket 331, the locking buckle 324 is located inside the buckle groove 334 and will move in an arc along the inner wall of the buckle groove 334 under the action of gravity. Thus, through the locking buckle 324 and the connecting rod 323, the fixed bracket 331 and the movable bracket 311 are tightly connected and will not easily separate.

[0029] In use, after the battery cell is inserted, the movable bracket 311 moves closer to the fixed bracket 331. The contact strip 316 is inserted between the adjacent connecting partitions 2. The vertical slide 315 slides synchronously on the inner wall of the bottom slide 332. The placed battery cell is positioned as a whole by the connecting partition 2 and the fixed partition 312. The contact strip 316 extends into the space at the bottom of the battery cell pack to assist in adjusting the bottom edge of the battery cell pack. After the movable bracket 311 and the fixed bracket 331 are combined, the connecting rod 323 is moved to a horizontal position to drive the locking buckle 324 into the interior of the straight slide 333. When the movable bracket 311 contacts the fixed bracket 331, the locking buckle 324 is located inside the buckle groove 334 and will move along the inner wall of the buckle groove 334 in an arc shape under the action of gravity. The locking buckle 324 and the connecting rod 323 will make the fixed bracket 331 and the movable bracket 311 tightly connected and not easily separated.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
