Description

Technical Field

[0001] This utility model relates to the technical field of battery processing, and in particular to a battery cell flipping and casing device. Background Technology

[0002] The casing is a crucial step in the cell structure packaging, directly affecting the battery's sealing performance, shock resistance, and thermal management. For example, prismatic and cylindrical batteries require laser welding to ensure a sealed casing and prevent electrolyte leakage.

[0003] During the battery cell packaging process, one end of the cell needs to be welded to the casing first, then the cell is flipped into the casing, and finally the other end of the cell is welded to the casing. During this process, the casing needs to be clamped and secured to ensure precise insertion of the cell. However, for cells with flanges, the casing is thin and its sides are uneven, making it difficult to clamp and secure the casing. Utility Model Content

[0010] A flipping drive is driven to the clamping structure to drive the clamping structure to rotate relative to the pressing structure, thereby transferring the battery cell into the housing.

[0011] Driven by the clamping drive, the clamping component approaches the fixed position to clamp the edge of the cover located at the fixed position, thereby limiting the cover; the clamping structure clamps the battery cell, and the flipping drive drives the clamping structure to rotate relative to the clamping structure, causing the battery cell to rotate relative to the cover, thus allowing the battery cell to enter the cover; by clamping the edge of the cover with the clamping component, displacement of the cover can be effectively prevented, which is conducive to accurately feeding the battery cell into the cover and improving the quality of the finished product.

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] In the description of this utility model, it should be understood that features specified as "first" or "second" may explicitly or implicitly include one or more of those features. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] During the battery cell packaging process, one end of the battery cell needs to be welded to the casing first, then the battery cell is flipped into the casing, and finally the other end of the battery cell is welded to the casing. For battery cells with flanges, the casing is thinner and its sides are curved, making it difficult to clamp and fix the casing by clamping.

[0039] like Figures 1 to 2 As shown in the figure, a battery cell flipping and housing insertion device provided by this utility model includes a base 100, a pressing structure 200, a pressing drive 300, a clamping structure 400, and a flipping drive 510. The base 100 is provided with a fixing position 110 for supporting the housing cover 800. The pressing structure 200 is slidably disposed on the base 100. The pressing structure 200 includes a pressing member 210. The pressing drive 300 is used to drive the pressing member 210 to move closer to or away from the fixing position 110 to press or release the edge 810 of the housing cover 800 located at the fixing position 110. The clamping structure 400 is used to clamp the battery cell 710. The flipping drive 510 is drivenly connected to the clamping structure 400 to drive the clamping structure 400 to rotate relative to the pressing structure 200, so that the battery cell 710 is transferred into the housing cover 800.

[0040] Driven by the clamping drive 300, the clamping member 210 approaches the fixed position 110 to clamp the edge 810 of the shell cover 800 located at the fixed position 110, thereby limiting the shell cover 800; the clamping structure 400 clamps the battery cell 710, and the flipping drive 510 drives the clamping structure 400 to rotate relative to the clamping structure 200, so that the battery cell 710 rotates relative to the shell cover 800, thereby allowing the battery cell 710 to enter the shell cover 800; by clamping the edge 810 of the shell cover 800 by the clamping member 210, displacement of the shell cover 800 can be effectively prevented, which is conducive to accurately feeding the battery cell 710 into the shell cover 800 and improving the quality of the finished product.

[0041] The casing 800 of the battery cell 710 with flange edges is long and narrow, with curved sides in the width direction and a thin thickness, making it difficult to fix the casing 800 by clamping. This embodiment of the invention uses a clamping member 210 to press the edge 810 of the casing 800, thus limiting the casing 800's position, reducing the probability of slippage during the flipping and insertion process, and thereby improving the quality of the finished product. The housing cover 800 is placed on the fixing position 110 with its opening facing upwards. The clamping member 210 presses the edge 810 of the housing cover 800 to prevent displacement. The clamping structure 400 clamps the battery cell 710. The flipping drive member 510 drives the clamping structure 400 to rotate relative to the clamping structure 200, causing the battery cell 710 to flip into the housing cover 800. After the insertion operation is completed, the clamping drive member 300 drives the clamping member 210 away from the fixing position 110, thus releasing the housing cover 800. It should be noted that the clamping member 210 only presses the edge 810 of the housing cover 800. In the thickness direction of the housing cover 800, the clamping member 210 is offset from the opening of the housing cover 800 to prevent the clamping member 210 from covering the opening and affecting the insertion operation.

[0042] In some embodiments, such as Figures 2 to 3 As shown, at least two clamping members 210 are provided. Providing multiple clamping members 210 can enhance the clamping effect on the edge 810 of the cover 800. At least two clamping members 210 are located on different sides of the fixing position 110, which can apply pressure to the edge 810 of the cover 800 from different directions, making the force on the cover 800 more uniform and reducing the probability of the cover 800 shifting or tilting.

[0043] In some embodiments, such as Figures 2 to 3As shown, the clamping member 210 includes a first clamping member 211 and two second clamping members 212. The first clamping member 211 is located at the end of the fixed position 110 and is used to clamp the end edge 810 of the cover 800 located at the fixed position 110 to prevent one end of the cover 800 from tilting up. The two second clamping members 212 are arranged opposite to the two sides of the fixed position 110 and are used to clamp the side edges 810 of the cover 800 located at the fixed position 110 to clamp the two side edges 810 of the cover 800 to prevent the cover 800 from tilting. Of course, in other embodiments, the number of the first clamping member 211 and the second clamping member 212 can be set according to the size of the cover 800, and this embodiment of the present invention does not make a special limitation in this regard.

[0044] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the clamping structure 200 also includes a base frame 220 and multiple guide components 230. The base frame 220 is slidably disposed on the base 100 along the height direction of the base 100. The clamping member 210 is disposed on the base frame 220, and the guide components 230 correspond to the clamping member 210. The guide components 230 include a first guide member 231 disposed on the base 100 and a second guide member 232 disposed on the base frame 220. The cooperation of the first guide member 231 and the second guide member 232 guides the movement trajectory of the corresponding clamping member 210. The clamping drive member 300 is disposed on the base 100 and is used to drive the synchronous movement of each clamping member 210. That is to say, multiple clamping members 210 can be driven by one clamping drive member 300, reducing the number of parts and improving the integration of the device. This arrangement is more conducive to controlling the synchronous movement of multiple clamping members 210 and can ensure that all clamping members 210 are subjected to the same pressure and driving force, thereby making the pressure applied to the cover 800 more uniform. Different clamping elements 210 may be located on different sides of the fixed position 110. Multiple guide components 230 are provided to guide different clamping elements 210 to move in different directions. Under the premise of ensuring that the movement trajectories of each clamping element 210 do not interfere with each other, the movement stroke of the clamping elements 210 can be minimized.

[0045] Generally, the clamping drive 300 is a cylinder, and the tilting drive 510 is a motor; the clamping drive 300 is fixed on the base 100, and the output shaft of the clamping drive 300 is connected to the base frame 220; the cover 800 is placed horizontally on the base 100, and the driving direction of the clamping drive 300 is up and down, so that the base frame 220 rises or falls relative to the base 100; the first guide 231 is disposed on the base 100, and the second guide 232 is disposed on the base frame 220. Under the action of the clamping drive 300, the first guide 231 moves relative to the second guide 232 to guide the movement trajectory of the corresponding clamping member 210.

[0046] In some embodiments, such as Figure 3 and Figure 4 As shown, the second guide 232 is a guide wheel, and the first guide 231 is provided with a guide surface 212a that abuts against the guide wheel. The guide wheel is on the guide surface 212a, which can reduce the friction between the first guide 231 and the second guide 232 and reduce energy loss.

[0047] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the guide surface 212a is located on the side of the guide wheel facing away from the base frame 220, and the guide surface 212a is inclined in the direction away from the base 100 towards the direction away from the fixed position 110. The movement trajectory of the clamping member 210 is guided by the cooperation of the guide wheel and the guide surface 212a. The clamping drive member 300 drives the base frame 220 to move in the direction away from the base 100, that is, the base frame 220 rises, and the guide wheel rises accordingly and slides on the guide surface 212a. Since the guide surface 212a is in the direction away from the base 100... The upper part is tilted in the direction away from the fixed position 110, so that the clamping member 210 moves in the direction away from the base 100 and away from the fixed position 110, thereby guiding the movement trajectory of the clamping member 210; the clamping member 210 moves in the direction away from the base 100, so that the clamping member 210 moves upward to release the cover 800; the clamping member 210 moves in the direction away from the fixed position 110, so that the clamping member 210 is transferred outside the fixed position 110, so as to avoid the clamping member 210 from obstructing the removal or placement of the cover 800.

[0048] In some embodiments, such as Figure 1 , Figure 3 and Figure 4As shown, the clamping structure 200 also includes a first support frame 240, a second support frame 250, a first elastic member 260, and a second elastic member; the first support frame 240 is slidably disposed on the base frame 220 to be close to or away from the fixed position 110, the second support frame 250 is slidably disposed on the first support frame 240 along the height direction of the base 100, and the clamping member 210 and the second guide member 232 are fixed on the second support frame 250; the first elastic member 260 is disposed on the base frame 220, and the second elastic member is disposed on the first support frame 240. Support frame 240; First elastic member 260 provides elastic force to support frame, first elastic member 260 applies force to support frame in the direction close to fixed position 110, second elastic member provides elastic force to second support frame 250, second elastic member applies force to second support frame 250 in the direction away from base 100, so that second guide member 232 abuts against second guide member 232, which is beneficial to guide the movement trajectory of clamping member 210 through the cooperation of first guide member 231 and second guide member 232. For example, a first guide rail 221 is provided on the base frame 220, and a first support frame 240 is slidably disposed on the first guide rail 221 to be close to or away from the fixed position 110; a second guide rail 241 is provided on the first support frame 240, and the second guide rail 241 is disposed along the height direction of the base 100, and a second support frame 250 is slidably disposed on the second guide rail 241; both the first elastic member 260 and the second elastic member are springs, one end of the first elastic member 260 is connected to the side of the first guide rail 221 away from the fixed position 110, and the other end is connected to the first support frame 240; one end of the second elastic member is connected to the side of the second guide rail 241 close to the base 100, and the other end is connected to the second support frame 250.

[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the clamping structure 400 includes a flipping frame 410 and a clamping member 420 disposed on the flipping frame 410. The flipping frame 410 is rotatably connected to the base 100, which facilitates the rotation of the clamping structure 400 relative to the pressing structure 200. The clamping member 420 is used to clamp the battery cell 710. When the flipping frame 410 rotates to the base 100, the clamping member 420 and the pressing member 210 are staggered. Under the premise that the clamping member 420 clamps the battery cell 710 and the pressing member 210 presses the housing cover 800, the clamping member 420 and the pressing member 210 are prevented from interfering with each other during the process of the battery cell 710 entering the housing cover 800, thus affecting the housing insertion operation.

[0050] In some embodiments, such as Figure 1 and Figure 2As shown, the clamping member 420 includes a clamping drive unit 421, a first clamping part 422, and a second clamping part 423. The clamping drive unit 421 is used to drive the first clamping part 422 and the second clamping part 423 to move closer to or further away from each other to clamp or release the battery cell 710. The clamping drive unit 421 can be a cylinder. There are two clamping drive units 421. One clamping drive unit 421 is used to drive the first clamping part 422 to move closer to or further away from the second clamping part 423, and the other clamping drive unit 421 is used to drive the second clamping part 423 to move closer to or further away from the first clamping part 422. The ends of the first clamping part 422 and the second clamping part 423 are both provided with claws, which are used to abut against the battery cell 710; the end of the clamping member 210 is provided with a clamping part 213, which is used to abut against the edge 810 of the cover 800; when the flipping frame 410 is rotated onto the base 100, the clamping member 420 and the clamping member 210 are misaligned, which means that when the flipping frame 410 is rotated onto the base 100, the claws of the clamping member 420 and the clamping part 213 of the clamping member 210 are misaligned. The second clamping member 212 is used to clamp the side edge 810 of the cover 800 located at the fixed position 110. The cover 800 is elongated. In order to achieve a better clamping effect, the second clamping member 212 can be provided with two clamping parts 213. The two clamping parts 213 are spaced apart along the length of the cover 800. When the flipping frame 410 rotates onto the base 100, the gripper of the clamping part is located in the gap between the two clamping parts 213 to effectively prevent interference.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, both the first clamping part 422 and the second clamping part 423 are provided with an arc-shaped support surface 424 that abuts against the battery cell 710. The arc-shaped support surface 424 allows the first clamping part 422 and the second clamping part 423 to fit against the surface of the battery cell 710, thereby increasing the contact area between the first clamping part 422 and the battery cell 710 and between the second clamping part 423 and the battery cell 710, and thus improving the clamping effect of the clamping member 420 on the battery cell 710. The shape of the support surface 424 can be set according to the specific shape of the battery cell 710, and this embodiment of the utility model does not make any special limitation in this regard.

[0052] In some embodiments, such as Figure 1 and Figure 2As shown, the clamping structure 400 also includes a floating member 430 and an elastic member. The elastic member connects the floating member 430 and the flipping frame 410. The elastic member is used to make the floating member 430 float and rise relative to the flipping frame 410. The floating member 430 is provided with a support position for supporting the battery cell 710. The base 100 is provided with a pressing member. When the flipping frame 410 rotates onto the base 100, the battery cell 710 enters the housing cover 800. At this time, the pressing member abuts against the floating member 430, causing the floating member 430 to descend relative to the flipping frame 410, which helps the battery cell 710 to disengage from the support position. The elastic member can be a spring.

[0053] The battery cell 710 has tabs at its end. During the flipping process of the clamping structure 400, the tabs of the battery cell 710 may shift due to gravity, affecting the quality of the finished product.

[0054] In the process of flipping the battery cell into the casing, the relevant technology usually does not limit the tabs of the battery cell, which makes the tabs of the battery cell easy to shift during the flipping process, affecting the quality of the product.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, the cell flipping and housing insertion device also includes a tab limiting assembly 600, which is disposed on the flipping frame 410. The tab limiting assembly 600 includes a tab limiting member 610 and a tab limiting drive member 620. The tab limiting drive member 620 is used to drive the tab limiting member 610 closer to the cell 710 to limit the tab located between the cell 710 and the tab limiting member 610, and to drive the tab limiting member 610 away from the cell 710 when the clamping structure 400 is rotated to a set angle to release the tab.

[0056] During the flipping and insertion process, the electrode limiter 610 abuts against the electrode. When the cell clamping structure 400 rotates to a set angle, it moves away from the cell 710 to release the electrode. This does not affect the insertion operation and can prevent the first electrode from shifting due to gravity during the flipping process. This helps to keep the relative position between the cell 710 and the electrode unchanged, thereby ensuring the quality of the finished product.

[0057] Because the tabs are made of a relatively soft material and are not welded to the housing cover 800, during the rotation of the cell clamping structure 400 relative to the housing cover 800 by the flipping drive 510, the cell 710 rotates with the cell clamping structure 400 and is subject to gravity, causing the tabs to easily shift, affecting the quality of the finished product. In this embodiment, the tab limiting member 610 limits the tabs during the flipping and insertion process, preventing the tabs from shifting during the flipping process. When the cell clamping structure 400 rotates to a set angle... In the case of a certain angle, the electrode limiter 610 is moved outside the electrode under the action of the limiter drive to release the electrode and avoid interference; the electrode limiter drive 620 can be a cylinder; the angle of the cell clamping structure 400 in the initial state is set to 0 degrees. Under normal circumstances, the cell clamping structure 400 rotates by a certain degree to transfer the cell 710 into the shell cover 800; the set angle can be any angle between 0 and 10 degrees; for example, the set angle can be 75 degrees, 77 degrees, 80 degrees, 81 degrees, 87 degrees, or 89 degrees.

[0058] In some embodiments, the tab limiting member 610 is provided with a step that abuts against the tab.

[0059] Understandably, because the tab has been bent, its surface is not perfectly flat. To better fit the tab, the tab retainer 610 uses a step to abut against it, increasing the contact area between the retainer 610 and the tab, thus improving the retaining effect. Generally, the bent tab is Z-shaped. The step allows the retainer 610 to conform to the shape of the tab when it abuts against it, preventing damage to the shape of the tab.
