Description

Technical Field

[0001] This application relates to the field of battery cell production, and in particular to a battery cell finishing device and production equipment. Background Technology

[0002] In the battery cell manufacturing process, the precise cutting of the separator and the stable connection of the cell finishing process are key factors affecting production efficiency and cost control. In traditional processes, separator cutting and cell pressing are typically handled by separate workstations, each with its own independent drive mechanism. While this separate structure achieves basic functionality, it has significant drawbacks in practical applications. Due to partial overlap in the operating logic of the two components, redundant mechanical actions occur; for example, the transfer and positioning after separator cutting requires additional steps, increasing equipment complexity and the number of parts. Furthermore, the separate workstation design results in a larger overall equipment footprint, and the repetitive configuration of drive units not only raises manufacturing costs but also prolongs process connection time due to insufficient mechanical coordination, reducing production line efficiency. More importantly, traditional designs struggle to adapt to the production needs of multiple battery cell models. Adjusting the compatibility of cells with different diameters requires frequent equipment switching or modifications, further restricting production flexibility and economy. Utility Model Content

[0040] This application provides a battery cell finishing device, which includes a mounting component 100, a first linear drive assembly 200, a cutting assembly 300, and a pressing assembly 500. Specifically, the mounting component 100 has a clearance groove 110. The first linear drive assembly 200 is fixedly mounted on the mounting component 100. The moving end of the first linear drive assembly 200 is connected to a driven component 210, which is slidably mounted on the mounting component 100. The cutting assembly 300 is mounted on the driven component 210. A centering and pressing assembly 400 is mounted on the end of the driven component 210. The pressing assembly 500 is located on the side of the driven component 210 away from the cutting assembly 300. The pressing assembly 500 passes through the clearance groove 110 and is located on the side of the mounting component 100 away from the driven component 210.

[0041] In this embodiment, "cell finishing" refers to cutting the cell from the upstream diaphragm after winding the cell and then abutting the cell to prevent the wound cell from loosening.

[0042] See Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, in this application, the cutting component 300, the centering and pressing component 400, and the pressing component 500 are all mounted on the driven member 210. When the first linear drive component 200 drives the driven member 210 to move, the cutting component 300, the centering and pressing component 400, and the pressing component 500 will all move synchronously with the driven member 210, thereby improving the coordination and linkage between the components, increasing the production efficiency of the production line, and reducing the space occupied by the entire device.

[0043] Please continue reading. Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, in the initial state, guide roller a is located above winding needle b, and diaphragm c contacts and passes over guide roller a and winding needle b. At this time, diaphragm c between guide roller a and winding needle b is in an inclined state. When the cell needs to be finished, the first linear drive assembly 200 first drives the driven member 210 to move towards the cell winding direction, driving the cutting assembly 300, centering and pressing assembly 400 and pressing assembly 500 to move to the predetermined position. Then, the centering and pressing assembly 400 first makes the diaphragm c vertical and abuts against the position of the diaphragm c, so that the tail of the diaphragm c contacts the winding needle b at the winding station. Here, the winding station can be... The first station is set up to facilitate subsequent cutting. Next, the cutting component 300 is activated to cut the diaphragm c in the vertical state, completing the cutting process of the diaphragm c. The cell station at the position of the pressing component 500 is the second station. The winding needle at the second station has a cell that has been wound. Then, the pressing component 500 abuts against the outer surface of the wound cell. After the diaphragm c is cut, the wound cell is driven to rotate by the winding needle at the second station. With the pressing component 500 abutting against the outer surface of the cell, the remaining diaphragm c that is connected to the wound cell at the second station wraps around the cell, thus completing the finishing work.

[0044] In some specific embodiments, the first linear drive assembly 200 includes a mounting base 201 fixedly mounted on the mounting member 100, a lead screw 202 rotatably mounted on the mounting base 201, a transmission member 203 fixedly connected to the driven member 210 via the lead screw 202, and a first rotary drive member 204 fixedly mounted on the mounting member 100 at the power input end of the lead screw 202.

[0045] See Figure 4As shown, the first linear drive assembly 200 drives the driven member 210 to move toward the cell winding station. Specifically, when it is necessary to drive the driven member 210 to move, the first rotary drive assembly 204 first drives the lead screw 202 to rotate. With the lead screw 202 connected to the transmission assembly 203, the lead screw 202 converts the power from the rotation of the first rotary drive assembly 204 into the power for the transmission assembly 203 to move, thereby causing the mounting base 201, which is fixedly connected to the transmission assembly 203, to move toward or away from the cell winding station.

[0046] For example, the first rotary drive 204 can be selected as a motor, specifically a servo motor. In order to provide sufficient force to the mounting base 201, a reducer can be installed at the output end of the first rotary drive 204. The rotary output end of the reducer is connected to the lead screw 202. The rotary output end of the reducer can be connected to the lead screw 202 through a coupling. In this embodiment, whether or not to use the reducer can be selected according to the actual situation, and there is no limitation here.

[0047] In some specific embodiments, the cutting assembly 300 includes a first slide plate 310 slidably mounted on the follower 210, a cutter 320 fixedly mounted at the end of the first slide plate 310, and a second linear drive assembly 330 fixedly mounted on the follower 210, the second linear drive assembly 330 driving the first slide plate 310 to move on the follower 210.

[0048] See Figure 5 As shown, when the diaphragm needs to be cut, the first linear drive assembly 200 drives the follower 210 to a predetermined position, and then the second linear drive assembly 330 drives the first slide plate 310 to move toward the diaphragm in a vertical state at the winding station. As the first slide plate 310 moves, the cutter 320 will contact the diaphragm and cut it, thus completing the diaphragm cutting process.

[0049] In some specific embodiments, an electric heating element 340 is fixedly installed on the first slide plate 310 at the position of the cutter 320.

[0050] Please continue reading. Figure 5 As shown, an electric heating element 340 is installed at the end of the first slide plate 310. The electric heating element 340 heats the cutter 320, thereby facilitating the cutter 320 to cut the diaphragm. It can be understood that the electric heating element 340 can convert electrical energy into heat energy to heat the cutter 320 to a preset temperature, which meets the temperature required for convenient diaphragm cutting. The specific type and specific temperature of the electric heating element 340 are not limited here, and can be designed and used according to needs.

[0051] In some specific embodiments, the second linear drive assembly 330 includes a second rotary drive 331 fixedly mounted on the follower 210. A turntable 332 is mounted on the power output end of the second rotary drive 331. A connecting rod 333 is eccentrically mounted on the turntable 332. The end of the connecting rod 333 away from the turntable 332 is rotatably connected to the first slide plate 310.

[0052] Please continue reading. Figure 5 As shown, in order to enable the cutter 320 to move toward or away from the diaphragm, the turntable 332 is rotated by the second rotary drive 331. Since one end of the connecting rod 333 is hinged to the eccentric position of the turntable 332 and the other end is hinged to the first slide plate 310, the first slide plate 310 will slide on the driven member 210 under the transmission of the connecting rod 333 while the turntable 332 rotates, thereby enabling the cutter 320 to move toward or away from the diaphragm.

[0053] For example, the second rotary drive 331 can be selected as a motor, specifically a servo motor.

[0054] In one embodiment, the second linear drive assembly 330 may also be composed of linear drive modules such as cylinders, motor lead screws, and linear modules; the specific type is not limited here.

[0055] In some specific embodiments, the centering clamping assembly 400 includes a first connecting plate 410 fixedly installed on the end of the driven member 210, and an abutment wheel 420 rotatably installed on the end of the first connecting plate 410; at least two slide rods 430 are slidably installed on the end of the driven member 210, and a movable plate 440 is fixedly provided on the end of the two slide rods 430 away from the driven member 210; an elastic member 450 is sleeved on the slide rods 430, and the elastic member 450 is located between the movable plate 440 and the driven member 210; a first pressure wheel 460 is rotatably installed on the end of the movable plate 440 away from the driven member 210.

[0056] See Figure 4 , Figure 6 as well as Figure 8 As shown, in this embodiment, in order to facilitate the cutting of the diaphragm, the abutment wheel 420 first abuts against the diaphragm. As the driven member 210 drives the abutment wheel 420 to continue moving towards the diaphragm, the diaphragm located between the guide roller and the winding needle is in a vertical state. That is, during the movement of the driven member 210, the abutment wheel 420 is moved and abuts against the diaphragm, so that the diaphragm changes from an inclined state to a vertical state, thereby facilitating the cutting blade 320 to cut the diaphragm.

[0057] Furthermore, before the cutter 320 cuts the diaphragm, in order to prevent the diaphragm from unwinding from the wound cell at the second station, the diaphragm at the winding needle position needs to be abutted and fixed to prevent the diaphragm on the cell at the second station from unwinding. It can be understood that when the driven member 210 moves and drives the abutting wheel 420 to move towards the diaphragm, it will also drive the first pressure wheel 460 to move towards the winding needle. The first pressure wheel 460 abuts the diaphragm against the outer circumference of the winding needle. At this time, the diaphragm in the cell will not unwind during the cutting process of the cutter 320.

[0058] It is understandable that when the first pressure roller 460 moves and comes into contact with the winding needle, the elastic element 450 will be compressed under force. Under the elastic force of the elastic element 450, the first pressure roller 460 will press the diaphragm tightly against the circumference of the winding needle.

[0059] In some specific embodiments, the pressing component 500 includes a second connecting plate 510 fixedly connected to the driven member 210, a second sliding plate 520 slidably mounted on the second connecting plate 510, a second pressure roller 530 rotatably mounted at the end of the second sliding plate 520, and a linear drive member 540 fixedly mounted on the second connecting plate 510, the drive end of the linear drive member 540 being connected to the second sliding plate 520 in a transmission connection.

[0060] See Figure 1 , Figure 3 , Figure 4 as well as Figure 7 As shown, the second connecting plate 510 is fixedly connected to the bottom surface of the driven member 210 through two upright plates passing through the clearance groove 110, so that the second connecting plate 510 can move synchronously with the driven member 210. After the first linear drive assembly 200 drives the driven member 210 to move to the predetermined position, the linear drive assembly 540 drives the second slide plate 520 to move towards the cell at the second station, so that the outer surface of the second pressure roller 530 presses against the outer surface of the cell. After the diaphragm at the first station is cut, the cell at the second station rotates. Since the second pressure roller 530 presses against the outer surface of the cell, the remaining tail diaphragm can be wrapped around the outer surface of the cell.

[0061] In some specific embodiments, the cell finishing device further includes a first positioning component 600, which includes a first driven piece 610 fixedly mounted on the driven member 210. A plurality of first sensors 620 are fixedly mounted on the mounting member 100, and the first sensors 620 are located on the movement path of the first driven piece 610.

[0062] See Figure 4As shown, in order to accurately control the moving distance of the driven member 210, a plurality of first sensors 620 are provided on the upper surface of the mounting member 100. The first sensors 620 are installed in a predetermined position, and then a first driven piece 610 is installed on the driven member 210. During the movement of the first driven piece 610, the first sensors 620 are triggered to determine the position reached by the driven member 210, thereby realizing the position positioning of the driven member 210.

[0063] It should be noted that there is no limitation on the number and installation location of the first sensor 620. The location and number can be adaptively selected according to the actual movement stroke of the follower 210.

[0064] In some specific embodiments, the cell finishing device further includes a second positioning component 700, which includes a second driven piece 710 fixedly mounted on the first sliding plate 310. A plurality of second sensing pieces 720 are fixedly mounted on the driven piece 210, and the second sensing pieces 720 are located on the movement path of the second driven piece 710.

[0065] Please continue reading. Figure 4 As shown, in order to accurately control the moving distance of the first slide plate 310, multiple second sensor plates 720 are installed on the driven member 210. The second driven plates 710 are installed on the first slide plate 310. During the movement of the first slide plate 310, it will pass through the second sensor plates 720 and trigger them. Then, it can be known that the position of the first slide plate 310 at this time and whether the moving distance has reached the predetermined position, so as to realize the position positioning judgment of the first slide plate 310.

[0066] It should be noted that the number and installation position of the second sensor 720 are not limited here. The specific number and installation position can be adaptively selected according to the actual movement of the first slide plate 310.

[0067] In this embodiment, the first sensor 620 and the second sensing plate 720 mentioned above can both be photoelectric sensors. The first driven plate 610 and the second driven plate 710 can be blocking plates. When the blocking plate moves to the position of the photoelectric sensor, it can be sensed by the photoelectric sensor, thereby determining the specific position.
