Position adjustment device

Abstract

The application relates to a position adjusting device which comprises a platform, a plurality of universal assemblies arranged on the platform, a bearing plate and an adjusting mechanism. Each universal assembly comprises a base arranged on the platform and a universal ball rollably embedded on the top of the base; the bearing plate is placed on the universal balls and used for bearing an electric core; and the adjusting mechanism is arranged on the platform and used for moving the electric core to a target position. A soft package electric core can be placed on the bearing plate, and then the adjusting mechanism is used for pushing the soft package electric core from the four sides to adjust the position. The lower surface of the soft package electric core keeps static friction with the top surface of the bearing plate, and the bearing plate can be moved to the target position under the driving of the soft package electric core. At this time, the universal balls on the bottom surface of the bearing plate also rotate. In the whole position adjusting process, the soft package electric core does not slide relative to the bearing plate, so that new scratches are avoided on the surface of the soft package electric core, and the electric core is effectively protected.

Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a position adjustment device. Background Technology

[0002] The manufacturing process of pouch cells involves numerous steps, often requiring scanning and inspection of the pouch cells and multiple transfers. Whether it is scanning and inspecting the surface of the pouch cells or transferring them, precise positional adjustments are necessary to ensure the accuracy of the inspection and that the gripping device can accurately pick up the pouch cells during transfer.

[0003] However, in the traditional manufacturing process, when adjusting the position of the pouch cell, it is difficult to avoid leaving scratches on the surface of the pouch cell, which damages the outer protective layer of the cell, increases the risk of the chemical substances inside the cell being exposed to the external environment, and may also increase the risk of short circuit, overheating, or even fire and explosion of the cell.

[0004] The information disclosed above in the background art of this application is only used to understand the background of the concept of this application, and may contain information that does not constitute prior art. Summary of the Invention

[0005] Therefore, in order to address the above problems, it is necessary to provide a position adjustment device.

[0006] This application provides a position adjustment device, which includes:

[0007] platform;

[0008] Multiple universal components are mounted on the platform, each of the universal components including a base mounted on the platform and a universal ball that is rotatably embedded in the top of the base;

[0009] A support plate, which is placed on the plurality of omnidirectional balls and is used to support the battery cells;

[0010] An adjustment mechanism is provided on the platform and is used to move the battery cell to the target position.

[0011] The aforementioned position adjustment device offers at least the following advantages: It allows the pouch cell to be placed on a support plate, and then the adjustment mechanism pushes the pouch cell to adjust its position. The lower surface of the pouch cell maintains static friction with the top surface of the support plate, allowing the support plate to move to the target position under the influence of the pouch cell. At this time, the omnidirectional ball on the bottom surface of the support plate also rotates. Once the pouch cell reaches the target position, surface inspection or transfer can be performed. It is important to emphasize that the pouch cell will not slide relative to the support plate during the entire position adjustment process, thus avoiding new scratches and damage to the surface of the pouch cell and effectively protecting it.

[0012] In one embodiment, the adjustment mechanism includes a first adjustment component and a second adjustment component disposed on the platform; the first adjustment component is used to move the battery cell and the support plate below the battery cell in the length direction of the support plate, and the second adjustment component is used to move the battery cell and the support plate below the battery cell in the width direction of the support plate until the battery cell moves to the target position.

[0013] In one embodiment, the first adjustment component includes two first clamping members. Each first clamping member includes a first slide rail disposed on the platform and parallel to the length direction of the support plate, a first slide plate slidably disposed on the first slide rail, and a first gripper connected to the first slide plate. One first gripper is used to abut against one side of the battery cell from the length direction of the support plate, and the other first gripper is used to abut against the other side of the battery cell from the length direction of the support plate.

[0014] The second adjustment component includes two second clamping members. Each second clamping member includes a second slide rail disposed on the platform and parallel to the width direction of the support plate, a second slide plate slidably disposed on the second slide rail, and a second gripper connected to the second slide plate. One second gripper is used to abut against one side of the battery cell from the width direction of the support plate, and the other second gripper is used to abut against the other side of the battery cell from the width direction of the support plate.

[0015] In one embodiment, the carrier plate includes a main board and a flange connected to the periphery of the main board. The flange extends towards the platform and is angled to the main board. The outer contour of the main board is rectangular. Each first sliding plate is provided with a first positioning block located below the main board and used to abut against the flange. Each second sliding plate is provided with a second positioning block located below the main board and used to abut against the flange. The adjustment mechanism can also move the carrier plate without the battery cell to an initial position. In the initial position, the two first positioning blocks abut against the two flanges in the length direction of the main board, and the two second positioning blocks abut against the two flanges in the width direction of the main board. Understandably, when the pouch cell is initially placed on the carrier plate, it may not be directly facing the carrier plate. When the pouch cell moves to the target position, the position of the carrier plate has deviated from the initial position. If it is not corrected in time, it may affect the effective support of the carrier plate for the next pouch cell. Therefore, this embodiment emphasizes that the carrier plate can be reset to the initial position under the action of the adjustment structure. When there is no pouch cell to be supported on the carrier plate, the two first sliding plates move away from each other along the length direction until the two first positioning blocks abut against the inner wall of the flange respectively. The two second sliding plates move away from each other along the width direction until the two second positioning blocks abut against the inner wall of the flange respectively. During this process, the carrier plate will be pulled back to the initial position by the two first positioning blocks and the two second positioning blocks.

[0016] In one embodiment, the number of universal joints is set to at least four. In the initial position, the four universal joints are centrally symmetrically distributed at the four corners of the motherboard, and the base of each universal joint is spaced apart from the flange. The universal joints are evenly distributed, especially with four of them located at the four corners of the support plate, which provides a more balanced and stable support for the support plate, preventing the soft-pack battery cells supported on it from sliding or falling due to tilting of the support plate.

[0017] In one embodiment, the position adjustment device further includes a drive device disposed on the platform, the drive device being connected to the first slide plate and used to drive the first slide plate to slide along the first slide rail. The drive device may include, but is not limited to, a cylinder, a motor, etc.

[0018] In one embodiment, the position adjustment device further includes a photoelectric sensor disposed on the platform, and a positioning piece is provided on the first skateboard. The photoelectric sensor is used to detect the positioning piece to achieve positioning of the first skateboard.

[0019] In one embodiment, the position adjustment device further includes two buffers disposed on the platform. The two buffers are arranged parallel to each other and spaced apart along the length of the first slide rail. A buffer block is provided on the first slide plate, and one end of the buffer block extends between the two buffers. The buffers can buffer the movement of the first slide plate and the battery cell driven by the first slide plate, preventing the soft-pack battery cell from sliding relative to the support plate due to excessive thrust caused by the first slide plate moving too rapidly.

[0020] In one embodiment, the number of the second adjustment components is set to two sets, with each first slide corresponding to one set of the second adjustment components. When each first slide moves along the length direction of the support plate, it can synchronously drive the two second slides to move closer or further apart in the width direction of the support plate.

[0021] In one embodiment, each of the first slide plates is provided with a limiting groove on each side in the width direction. The length extension direction of the limiting groove is set at an angle to the length direction of the support plate. Each of the second slide plates is provided with a limiting post, which is slidably disposed in the limiting groove. When the first slide plate moves along the length direction of the support plate, the groove wall of the limiting groove can abut against the outer side of the limiting post and make the limiting post slide in the limiting groove, thereby driving the second slide plate to move in the width direction of the support plate.

[0022] In one embodiment, the clamping member further includes a fixing member, an elastic member, and a guide rail. The guide rail is located on the side of the second sliding plate facing away from the main board and is parallel to the second sliding rail. The second gripper is slidably disposed on the guide rail. The fixing member is located on the side of the guide rail facing away from the support plate. One end of the elastic member is fixed to the fixing member, and the other end of the elastic member elastically abuts against the side of the second gripper facing away from the support plate. When the second gripper abuts against the battery cell on the support plate, the elastic member can contract under the action of external force. The elastic member can be a compression spring. Part of the force exerted when the second gripper abuts against the edge of the soft-pack battery cell can be transmitted to the elastic member. In other words, the elastic member acts as a buffer, preventing excessive force from the second gripper on the soft-pack battery cell, which could cause deformation of the battery cell or slippage of the battery cell relative to the support plate.

[0023] In one embodiment, the position adjustment device further includes a limiting member disposed on the platform; in the initial position, the limiting member is spaced apart from the edge of the support plate; when the support plate moves on the omnidirectional ball under the drive of the adjustment mechanism, the limiting member can limit the range of motion of the support plate.

[0024] In one embodiment, the support plate has an adsorption plate on the side facing away from the platform. The adsorption plate is used to adsorb and fix the battery cell. Each side of the adsorption plate has a clearance groove. The number of limiting members is set to two. The two limiting members are respectively located on both sides of the width direction of the support plate. One end of each limiting member is fixed to the platform. The other end of each limiting member is higher than the support plate and extends toward the clearance groove, and is provided with a limiting hook. The limiting hook extends into the clearance groove and is spaced apart from the top surface of the support plate.

[0025] In one embodiment, in the initial position, the limiting hook is spaced apart from the groove wall of the clearance groove; when the support plate moves on the universal ball under the drive of the adjustment mechanism, either side of the two edges of the support plate in the width direction can abut against the limiting member to restrict the movement of the support plate in the width direction, and either side of the two groove walls of the clearance groove in the length direction of the support plate can abut against the limiting hook to restrict the movement of the adsorption plate and the support plate in the length direction.

[0026] In one embodiment, the position adjustment device further includes a scanning component disposed on the platform. The scanning component is located below the support plate, the support plate has a first through hole, and the adsorption plate has a second through hole. The scanning component can scan the information code on the battery cell through the first through hole and the second through hole. Attached Figure Description

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments, this application provides a position adjustment device 10, which includes a platform 100, a plurality of universal joints 200 disposed on the platform 100, a support plate 300, and an adjustment mechanism 400. Each universal joint 200 includes a base 210 disposed on the platform 100 and a universal ball 220 rotatably embedded in the top of the base 210; the support plate 300 is placed on the plurality of universal balls 220 and is used to support a battery cell 840; the adjustment mechanism 400 is disposed on the platform 100 and is used to move the battery cell 840 to a target position.

[0041] The aforementioned position adjustment device 10 has at least the following beneficial effects: The flexible battery cell 840 can be placed on the support plate 300, and then the adjustment mechanism 400 pushes the flexible battery cell 840 to adjust its position. The lower surface of the flexible battery cell 840 maintains static friction with the top surface of the support plate 300. The support plate 300 can move to the target position under the influence of the flexible battery cell 840. At this time, the universal ball 220 on the bottom surface of the support plate 300 will also rotate. Once the flexible battery cell 840 has moved to the target position, surface inspection or transfer can be performed. It is important to emphasize that during the entire position adjustment process, the flexible battery cell 840 will not slide relative to the support plate 300, thereby avoiding new scratches and damage to the surface of the flexible battery cell 840 and effectively protecting the battery cell 840.

[0042] Specifically, such as Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the adjustment mechanism 400 includes a first adjustment component 410 and a second adjustment component 420 disposed on the platform 100, and the outer contour of the support plate 300 is rectangular; the first adjustment component 410 is used to move the battery cell 840 and the support plate 300 below the battery cell 840 in the length direction of the support plate 300, and the second adjustment component 420 is used to move the battery cell 840 and the support plate 300 below the battery cell 840 in the width direction of the support plate 300 until the battery cell 840 moves to the target position.

[0043] The first adjustment assembly 410 includes two first clamping members 411. Each first clamping member 411 includes a first slide rail 412 disposed on the platform 100 and parallel to the length direction of the support plate 300, a first sliding plate 413 slidably disposed on the first slide rail 412, and a first gripper 414 connected to the first sliding plate 413. One first gripper 414 is used to abut against one side of the battery cell 840 from the length direction of the support plate 300, and the other first gripper 414 is used to abut against the other side of the battery cell 840 from the length direction of the support plate 300. The first sliding plate 413 can be directly slidably disposed on the first slide rail 412, or it can be indirectly connected to the first slide rail 412 via a slider.

[0044] The second adjustment assembly 420 includes two second clamping members 421. Each second clamping member 421 includes a second slide rail 422 disposed on the platform 100 and parallel to the width direction of the support plate 300, a second sliding plate 423 slidably disposed on the second slide rail 422, and a second gripper 424 connected to the second sliding plate 423. One second gripper 424 is used to abut against one side of the battery cell 840 from the width direction of the support plate 300, and the other second gripper 424 is used to abut against the other side of the battery cell 840 from the width direction of the support plate 300. The second sliding plate 423 can be directly slidably disposed on the second slide rail 422, or it can be indirectly connected to the second slide rail 422 via a slider.

[0045] Specifically, such as Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the support plate 300 includes a main plate 310 and a flange 320 connected to the periphery of the main plate 310. The flange 320 extends toward the platform 100 and is angled toward the main plate 310. Each first slide plate 413 is provided with a first positioning block 415, which is located below the main plate 310 and abuts against the flange 320. Each second slide plate 423 is provided with a second positioning block 425, which is located below the main plate 310 and abuts against the flange 320. The adjustment mechanism 400 can also move the support plate 300 when it is not carrying the battery cell 840 to an initial position. In the initial position, the two first positioning blocks 415 abut against the two flanges 320 in the length direction of the main plate 310, and the two second positioning blocks 425 abut against the two flanges 320 in the width direction of the main plate 310. Understandably, when the pouch cell 840 is initially placed on the support plate 300, it may not be directly facing the support plate 300. When the pouch cell 840 moves to the target position, the position of the support plate 300 has deviated from the initial position. If it is not corrected in time, it may affect the effective support plate 300's ability to receive the next pouch cell 840. Therefore, this embodiment emphasizes that the support plate 300 can be reset to the initial position under the action of the adjustment structure. When there is no pouch cell 840 on the support plate 300, the two first sliding plates 413 move away from each other along the length direction until the two first positioning blocks 415 abut against the inner wall of the flange 320 respectively. The two second sliding plates 423 move away from each other along the width direction until the two second positioning blocks 425 abut against the inner wall of the flange 320 respectively. During this process, the support plate 300 will be pulled back to the initial position by the two first positioning blocks 415 and the two second positioning blocks 425.

[0046] More specifically, such as Figure 6 As shown, in some embodiments, the number of universal joints 200 is set to at least four. In the initial position, four of the universal joints 200 are centrally symmetrically distributed at the four corners of the main board 310, and the base 210 of each universal joint 200 is spaced apart from the flange 320. The universal joints 200 are evenly distributed, especially with four of them located at the four corners of the support plate 300, which can provide a more balanced and stable support effect for the support plate 300, preventing the support plate 300 from tilting and causing the soft-pack battery cell 840 supported on it to slide or fall off.

[0047] Please see Figure 6In some embodiments, the number of the second adjustment components 420 is set to two sets, with each first slide plate 413 corresponding to one set of the second adjustment components 420. When each first slide plate 413 moves along the length direction of the support plate 300, it can synchronously drive the two second slide plates 423 to move closer or further away from each other in the width direction of the support plate 300.

[0048] Furthermore, such as Figure 6 As shown, in some embodiments, each first slide plate 413 has a limiting groove 418 on each side in the width direction. The length extension direction of the limiting groove 418 is set at an angle to the length direction of the support plate 300. Each second slide plate 423 is provided with a limiting post 426, which is slidably disposed in the limiting groove 418. When the first slide plate 413 moves along the length direction of the support plate 300, the groove wall of the limiting groove 418 can abut against the outer side of the limiting post 426 and make the limiting post 426 slide in the limiting groove 418, thereby driving the second slide plate 423 to move in the width direction of the support plate 300.

[0049] Furthermore, such as Figure 6 As shown, in some embodiments, the position adjustment device further includes two buffers 500 disposed on the platform 100. The two buffers 500 are arranged parallel to each other and spaced apart along the length of the first slide rail 412. A buffer block 416 is provided on the first slide plate 413, and one end of the buffer block 416 extends between the two buffers 500. The buffers 500 can buffer the movement of the first slide plate 413 and the battery cell 840 driven by the first slide plate 413, and can prevent the first slide plate 413 from moving too rapidly, which would cause the soft-pack battery cell 840 to be subjected to excessive thrust and slide relative to the support plate 300.

[0050] Furthermore, such as Figure 6 As shown, in some embodiments, the position adjustment device further includes a drive device 600 disposed on the platform 100. The drive device 600 is connected to the first slide plate 413 and is used to drive the first slide plate 413 to slide along the first slide rail 412. The drive device 600 may include, but is not limited to, a cylinder, a motor, etc.

[0051] Furthermore, such as Figure 6 As shown, in some embodiments, the position adjustment device further includes a photoelectric sensor 700 disposed on the platform 100, and a positioning piece 417 is disposed on the first slide plate 413. The photoelectric sensor 700 is used to detect the positioning piece 417 to achieve positioning of the first slide plate 413.

[0052] Please see Figure 9 In some embodiments, the clamping member further includes a fixing member 427, an elastic member 428, and a guide rail 429. The guide rail 429 is disposed on the side of the second slide plate 423 facing away from the main board 310 and parallel to the second slide rail 422. The second gripper 424 is slidably disposed on the guide rail 429. The fixing member 427 is disposed on the side of the guide rail 429 facing away from the support plate 300. One end of the elastic member 428 is fixed to the fixing member 427, and the other end of the elastic member 428 elastically abuts against the side of the second gripper 424 facing away from the support plate 300. When the second gripper 424 abuts against the battery cell 840 on the support plate 300, the elastic member 428 can contract under the action of external force. The second gripper 424 can be directly slidably disposed on the guide rail 429 at its bottom, or it can be indirectly connected to the guide rail 429 via a slider. The elastic element 428 can be a compression spring. When the second gripper 424 abuts against the edge of the soft-pack battery cell 840, part of the force can be transmitted to the elastic element 428. In other words, the elastic element 428 plays a buffering role, which can prevent the second gripper 424 from exerting too much force on the soft-pack battery cell 840, which could cause the battery cell 840 to deform or the battery cell 840 to slide relative to the support plate 300.

[0053] Please see Figure 2 and Figure 3 In some embodiments, the position adjustment device further includes a limiting member 820 disposed on the platform 100; in the initial position, the limiting member 820 is spaced apart from the edge of the support plate 300; when the support plate 300 moves on the omnidirectional ball 220 under the drive of the adjustment mechanism 400, the limiting member 820 can limit the range of motion of the support plate 300.

[0054] Specifically, such as Figure 3 and Figure 9As shown, in some embodiments, the support plate 300 has an adsorption plate 810 on the side facing away from the platform 100. The adsorption plate 810 can be fixed to the support plate 300 by means of threaded connection, snap-fit, welding, bonding, etc. The adsorption plate 810 is used to adsorb and fix the battery cell 840. Each side of the adsorption plate 810 is provided with a relief groove. The number of limiting members 820 is set to two. The two limiting members 820 are respectively located on both sides of the width direction of the support plate 300. One end of each limiting member 820 is fixed to the platform 100. The other end of each limiting member 820 is higher than the support plate 300 and extends towards the relief groove, and is provided with a limiting hook 821. The limiting hook 821 extends into the relief groove 811 and is spaced apart from the top surface of the support plate 300 to limit the support plate 300 in the vertical direction.

[0055] More specifically, such as Figure 3 As shown, in some embodiments, in the initial position, the limiting hook 821 is spaced apart from the groove wall of the clearance groove 811; when the support plate 300 moves on the universal ball 220 under the drive of the adjustment mechanism 400, either side of the two edges of the support plate 300 in the width direction can abut against the limiting member 820 to restrict the movement of the support plate 300 in the width direction, and either side of the clearance groove 811 in the length direction of the support plate 300 can abut against the limiting hook 821 to restrict the movement of the adsorption plate 810 and the support plate 300 in the length direction.

[0056] More specifically, such as Figure 3 As shown, in one embodiment, the position adjustment device further includes a scanning component 830 disposed on the platform 100. The scanning component 830 is located below the support plate 300. The support plate 300 has a first through hole 331 and the adsorption plate 810 has a second through hole 812. The scanning component 830 can scan the information code on the battery cell 840 through the first through hole 331 and the second through hole 812.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.

[0060] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
