Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a battery cell transplanting device. Background Art

[0002] In battery processing and production, after the battery cell is injected with electrolyte, it needs to be transferred to a downstream resting station to allow the battery cell to rest so that the electrolyte can fully penetrate the positive electrode sheet, separator, and negative electrode sheet of the battery cell, thereby improving the battery cell's rate performance and cycle performance. Conversely, insufficient penetration can easily lead to high internal resistance of the battery cell and even adverse consequences such as lithium deposition. After penetration is completed, the battery cell is transferred to other downstream work stations to be processed into a battery.

[0003] Specifically, in the prior art, after injecting electrolyte into a battery cell, the cell is typically left to rest for several hours. Because the electrolyte's infiltration of the cell involves the contact and infiltration of three phases: solid, liquid, and gas, this resting process typically takes dozens of hours, resulting in low infiltration efficiency and thus impacting battery production efficiency.

[0034] See also Figures 1 to 5 This embodiment provides a battery cell transplanting device, which is used to transfer battery cells 100 after liquid injection. Specifically, the battery cell transplanting device includes a conveying mechanism 210, and the conveying mechanism 210 includes a first carrier plate 211. The first carrier plate 211 can support the battery cell 100, and the first carrier plate 211 can move in a horizontal direction, so as to be able to transport the battery cell 100 to a downstream work station.

[0035] Specifically, in this embodiment, the battery cells 100 placed on the first carrier plate 211 are placed along the first horizontal direction. This embodiment is described using cylindrical battery cells as an example. The axis of the battery cells 100 placed on the first carrier plate 211 extends along the first horizontal direction. In addition, the conveying mechanism 210 further includes a first driving member 212 and a second driving member 213, wherein the first driving member 212 is configured to drive the first carrier plate 211 to reciprocate in a second horizontal direction perpendicular to the first horizontal direction, and the second driving member 213 is configured to drive the first carrier plate 211 to rise and fall in a vertical direction.

[0036] In addition to the conveying mechanism 210, the battery cell transplanting device also includes an oscillation mechanism 220, which includes a second carrier plate 221 and a third driving member 222, wherein the second carrier plate 221 includes a first plate portion 2211 and a second plate portion 2212 arranged opposite to each other along the first horizontal direction, and the distance between the first plate portion 2211 and the second plate portion 2212 is less than the length of the battery cell 100. The first carrier plate 211 can be aligned with the second carrier plate 221 in the second horizontal direction, and the top of the first plate portion 2211 and the top of the second plate portion 2212 are respectively provided with a first accommodating groove 22111 and a second accommodating groove 22121, which can respectively accommodate the two ends of the battery cell 100, and the third driving member 222 is configured to drive the first plate portion 2211 and the second plate portion 2212 to rise and fall in the vertical direction.

[0037] Based on the above, in this embodiment, the first carrier plate 211 can first rise to a position higher than the second carrier plate 221. Thereafter, the first carrier plate 211 can drive the battery cell 100 to move along the second horizontal direction until it is aligned with the second carrier plate 221 in the second horizontal direction. Then, the first carrier plate 211 can be lowered vertically to a position lower than the second carrier plate 221, so that the battery cell 100 can be transferred from the first carrier plate 211 to the second carrier plate 221. Specifically, the two ends of the battery cell 100 can be respectively accommodated in the first accommodating groove 22111 and the second accommodating groove 22121. Thereafter, the third driving member 222 drives the first plate portion 2211 and the second plate portion 2212 to rise and fall in the vertical direction to vibrate the battery cell 100, thereby allowing the electrolyte to flow within the battery cell 100, thereby promoting rapid and sufficient absorption of the electrolyte. The first carrier plate 211 then returns to its original position along the second horizontal direction to support the next battery cell 100.

[0038] Based on the above, this embodiment vibrates the battery cell 100 during its transfer to promote rapid absorption of the electrolyte, thereby reducing the time required for the infiltration process, improving the infiltration efficiency, and thereby improving battery production efficiency. Furthermore, this embodiment ensures that the electrolyte is fully absorbed, thereby improving the performance of the subsequent battery production.

[0039] It can be understood that in other optional embodiments, the third driving member 222 can also be configured to drive the first plate portion 2211 or the second plate portion 2212 to rise and fall in the vertical direction, that is, the third driving member 222 can also be configured to drive any one of the first plate portion 2211 and the second plate portion 2212 to rise and fall in the vertical direction, so that the battery cell 100 supported on the second carrier plate 221 can swing, thereby allowing the electrolyte to flow inside the battery cell 100, thereby promoting the electrolyte to be quickly and fully absorbed. There is no specific limitation on this in this embodiment.

[0040] Furthermore, the oscillation mechanism 220 includes two or more second carriers 221, which are evenly arranged along the second horizontal direction. The number of first carriers 211 is one more than the number of second carriers 221, and all first carriers 211 are also evenly arranged along the second horizontal direction. In addition, the distance between any two adjacent first carriers 211 is equal to the distance between any two adjacent second carriers 221. All first carriers 211 can move synchronously in the second horizontal direction, and the distance a first carrier 211 moves along or away from the second horizontal direction is equal to the distance between two adjacent second carriers 221. This allows the battery cells 100 to be transferred stepwise from the second carrier 221 on the upstream side to the second carrier 221 on the downstream side.

[0041] Taking the example of the oscillation mechanism 220 including eight second carriers 221 and the conveying mechanism 210 including nine first carriers 211, the nine first carriers 211 can synchronously move back and forth in the second horizontal direction, and the stroke of each movement along or away from the second horizontal direction is equal to the distance between two adjacent second carriers 221.

[0042] Specifically, along the second horizontal direction, the frontmost one of the nine first carriers 211 can support the battery cell 100 after the liquid is injected, and the eight first carriers 211 are aligned with the eight second carriers 221 respectively. After that, all the first carriers 211 are first raised to be higher than the second carriers 221, and then all the first carriers 211 are moved along the second horizontal direction until the first eight first carriers 211 are aligned with the eight second carriers 221 one by one. After that, all the first carriers 211 are lowered along the vertical direction to be lower than the second carriers 221, so that the first carrier 211 newly placed at the front is aligned with the second carriers 221. The battery cells 100 on the plate 211 are transferred to the front-most second carrier plate 221, while the battery cells 100 originally supported on the first seven second carrier plates 221 are each transferred to the next second carrier plate 221. Furthermore, the battery cell 100 supported on the last second carrier plate 221 is moved away from the oscillation mechanism 220 by the last first carrier plate 211. This battery cell 100 has completed the impregnation process. The battery cell 100 moved away from the oscillation mechanism 220 can be removed from the last first carrier plate 211 by a robot or a worker for subsequent operations. Afterwards, all first carrier plates 211 are moved away from the second horizontal direction until the last eight first carrier plates 211 are aligned with the eight second carrier plates 221, allowing the battery cells 100 to be placed back on the front-most first carrier plate 211.

[0043] It can be understood that, when all the first carriers 211 move away from the second horizontal direction until the last eight first carriers 211 are aligned one by one with the eight second carriers 221 so as to re-place the battery cells 100 on the front-end first carrier 211, the third driving member 222 continues to drive the first plate portion 2211 and / or the second plate portion 2212 to rise and fall in the vertical direction, thereby oscillating the battery cells 100.

[0044] Based on the above, any battery cell 100 can undergo more than two shaking operations, thereby promoting faster and more sufficient absorption of the electrolyte, thereby further improving the production efficiency of the battery and further improving the performance of the subsequently produced battery.

[0045] In addition, it is worth noting that the third driving member 222 can drive all the second carrier plates 221 to move simultaneously. In other words, only one third driving member 222 is required in this embodiment.

[0046] Specifically, in this embodiment, the oscillation mechanism 220 also includes at least two first rotating shafts 223, which are evenly arranged along the second horizontal direction and extend along the first horizontal direction. The first gear 2231 and the second gear 2232 are respectively provided at both ends of the first rotating shaft 223. All second carrier plates 221 are correspondingly provided with a first rotating shaft 223, any two adjacent first gears 2231 are engaged, and any two adjacent second gears 2232 are engaged. The third driving member 222 can drive one of the first rotating shafts 223 to rotate around its axis. Under the action of the first gear 2231 and the second gear 2232, all the first rotating shafts 223 can rotate synchronously.

[0047] It is understandable that the third driving member 222 may be a stepping motor or a servo motor, etc., which is not specifically limited in this embodiment.

[0048] In addition, the first gear 2231 and the second gear 2232 correspond to the first plate portion 2211 and the second plate portion 2212 respectively, and the first gear 2231 and the first plate portion 2211 are spaced apart in the vertical direction, and the second gear 2232 and the second plate portion 2212 are spaced apart in the vertical direction. Based on the above, in this embodiment, the third driving member 222 is configured to drive the first plate portion 2211 and the second plate portion 2212 to rise and fall in the vertical direction. Specifically, the first plate portion 2211 is rotatably connected to the first connecting rod 2242 via the second rotating shaft 2241, and the end of the first connecting rod 2242 away from the first plate portion 2211 is rotatably connected to the first gear 2231 via the third rotating shaft 2243. The second plate portion 2212 is rotatably connected to the second connecting rod 2252 via the fourth rotating shaft 2251, and the second connecting rod 2252 is away from the second plate portion 2 One end of 212 is rotatably connected to the second gear 2232 through the fifth shaft 2253. The second shaft 2241, the third shaft 2243, the fourth shaft 2251 and the fifth shaft 2253 all extend along the first horizontal direction. During the rotation of the first shaft 223, the first gear 2231 and the second gear 2232 rotate accordingly. Under the action of the first connecting rod 2242, the first plate portion 2211 rises and falls in the vertical direction. Under the action of the second connecting rod 2252, the second plate portion 2212 rises and falls in the vertical direction, thereby being able to vibrate the battery cell 100.

[0049] It can be understood that in other optional embodiments, for any second carrier plate 221, it can also be set to only connect the first plate portion 2211 with the first gear 2231 through the first connecting rod 2242, or only connect the second plate portion 2212 with the second gear 2232 through the second connecting rod 2252, so that the third driving member 222 can drive the first plate portion 2211 or the second plate portion 2212 to rise and fall in the vertical direction.

[0050] Furthermore, for any second carrier plate 221, the movement directions of the first plate portion 2211 and the second plate portion 2212 are opposite. In the process of the third driving member 222 driving the first plate portion 2211 and the second plate portion 2212 to rise and fall in the vertical direction, the battery cell 100 supported on the second carrier plate 221 can swing, so that the electrolyte can flow fully inside the battery cell 100, thereby more effectively promoting the rapid and sufficient absorption of the electrolyte.

[0051] It is worth noting that this embodiment can control the swing speed and angle of the battery cell 100 by controlling the rotation speed of the first rotating shaft 223 and the lengths of the first connecting rod 2242 and the second connecting rod 2252, thereby further promoting faster and more sufficient absorption of the electrolyte.

[0052] Of course, in other optional embodiments, for any second carrier plate 221, the moving directions of the first plate portion 2211 and the second plate portion 2212 may also be the same, thereby oscillating the battery cell 100 through inertia. This embodiment does not impose any specific restrictions on this.

[0053] Furthermore, the battery cell transplanting device also includes a base frame 230, all the first plate portions 2211 and all the second plate portions 2212 are slidably connected to the base frame 230, specifically, all the first plate portions 2211 and all the second plate portions 2212 are provided with a first slide rail 22117, and the base frame 230 is fixedly connected with a first slider 231, all the first plate portions 2211 and all the second plate portions 2212 are correspondingly provided with a first slider 231, and the first plate portion 2211 and the second plate portion 2212 are slidably connected to the base frame 230 through the first slider 231 and the second slide rail 241, thereby ensuring that the first plate portion 2211 and the second plate portion 2212 can be accurately lifted and lowered in the vertical direction.

[0054] In addition, it is worth noting that, in this embodiment, the first plate portion 2211 includes a first plate member 22112 and a second plate member 22113, the first plate member 22112 is rotatably connected to the top of the second plate member 22113 through the sixth rotating shaft 22114, the first accommodating groove 22111 is arranged at the top of the first plate member 22112, and the sixth rotating shaft 22114 extends along the second horizontal direction. The second plate portion 2212 includes a third plate 22122 and a fourth plate 22123. The third plate 22122 is rotatably connected to the top of the fourth plate 22123 through the seventh rotating shaft 22124. The second accommodating groove 22121 is set at the top of the third plate 22122. The seventh rotating shaft 22124 extends along the second horizontal direction. The third driving member 222 can drive the second plate 22113 and / or the fourth plate 22123 to rise and fall in the vertical direction. When the battery cell 100 swings, the first plate 22112 can rotate around the axis of the sixth rotating shaft 22114, and the third plate 22122 can rotate around the axis of the seventh rotating shaft 22124, so that the first plate 22112 and the third plate 22122 can adaptively adjust their own positions according to the posture of the battery cell 100 during the swinging process of the battery cell 100, so that the battery cell 100 can always be stably supported during the swinging process of the battery cell 100.

[0055] Based on the above, a first limit block 22115 and a second limit block 22116 are respectively provided on both sides of the first plate 22112 along the first horizontal direction. The spacing between the first limit block 22115 and the second limit block 22116 is greater than the thickness of the first plate 22112 along the first horizontal direction. The first limit block 22115 and the second limit block 22116 can limit the rotation range of the first plate 22112, thereby preventing the battery cell 100 from falling off the second carrier plate 221 due to excessive rotation of the first plate 22112. Correspondingly, a third limit block 22125 and a fourth limit block 22126 are respectively provided on both sides of the third plate 22122 along the first horizontal direction. The distance between the third limit block 22125 and the fourth limit block 22126 is greater than the thickness of the third plate 22122 along the first horizontal direction. The third limit block 22125 and the fourth limit block 22126 can limit the rotation range of the third plate 22122, thereby preventing the battery cell 100 from falling off the second carrier plate 221 due to excessive rotation of the third plate 22122.

[0056] Furthermore, the first carrier plate 211 includes a third plate portion 2111 and a fourth plate portion 2112 arranged opposite to each other along a first horizontal direction. The distance between the third plate portion 2111 and the fourth plate portion 2112 is less than the length of the battery cell 100. The top of the third plate portion 2111 and the top of the fourth plate portion 2112 are respectively provided with a third accommodating groove 21111 and a fourth accommodating groove 21121. The third accommodating groove 21111 and the fourth accommodating groove 21121 can respectively accommodate the two ends of the battery cell 100, thereby ensuring that the first carrier plate 211 can stably drive the battery cell 100 to move.

[0057] Moreover, in this embodiment, the third plate portion 2111 and the fourth plate portion 2112 are located between the first plate portion 2211 and the second plate portion 2212 , that is, the first carrier plate 211 supports the middle portion of the battery cell 100 , thereby further ensuring that the first carrier plate 211 can stably drive the battery cell 100 to move.

[0058] It is worth noting that, in this embodiment, the two outermost ones of all the first rotating shafts 223 along the second horizontal direction are whole shafts extending along the first horizontal direction, while the first rotating shaft 223 located in the middle is a split structure including a first shaft portion 2233 and a second shaft portion 2234, wherein the first shaft portion 2233 and the second shaft portion 2234 are respectively installed on both sides of the base frame 230 along the first horizontal direction, and both extend along the first horizontal direction, a first gear 2231 is provided on the side of the first shaft portion 2233 away from the second shaft portion 2234, and a second gear 2232 is provided on the side of the second shaft portion 2234 away from the first shaft portion 2233, and the third driving member 222 is used to drive the one located outermost along the second horizontal direction among all the first rotating shafts 223 to rotate around its axis, thereby providing installation space for the conveying mechanism 210.
