Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a cell stacking device and a cell transfer device. Background Technology

[0002] In related technologies, some battery modules include single-row cells, while others include multi-row cells. Single-row cells simply require stacking multiple cells along a preset direction, while multi-row cells require stacking multiple cells along a preset direction to form a single-row cell, and then stacking multiple single-row cells in a direction perpendicular to the preset direction to form a double-row cell.

[0003] However, existing cell stacking devices can only stack multiple cells along a preset direction to produce a single row of cells. When stacking multiple single rows of cells along a direction perpendicular to the preset direction, the stacking is entirely done manually, which is inefficient and cannot meet the needs of the production line. Utility Model Content

[0004] One objective of this invention is to provide a battery cell stacking device that can stack not only single rows of battery cells but also multiple rows of battery cells, thereby improving the battery cell stacking efficiency.

[0005] Another objective of this invention is to provide a battery cell transfer device that can improve the efficiency of battery cell stacking and the convenience of battery cell transfer.

[0006] To achieve the above objectives, the following technical solution is provided:

[0007] Cell stacking device, including:

[0008] Base;

[0009] At least two stacking units are arranged side by side along a first direction; each stacking unit includes a slide, a fixed support, a movable support, and a first locking assembly. The slide is slidably disposed on the base along the first direction, the fixed support is fixed to the slide, and the movable support is slidably disposed on the slide along a second direction. The first locking assembly is capable of locking or unlocking the movable support to the slide. The second direction is perpendicular to the first direction.

[0010] To achieve the above objectives, a cell transfer device is also provided, including the cell stacking device and the automated guided vehicle as described above, wherein the base is disposed on the body of the automated guided vehicle.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The battery cell stacking device of this utility model places multiple battery cells on the same slide, and a movable support member presses the multiple battery cells against a fixed support member along a second direction. Then, a first locking component locks the movable support member and the slide, thereby realizing the stacking of a single row of battery cells. Then, the slides of multiple stacking units are slid along a first direction, so that the single rows of battery cells on the multiple slides can be stacked along the first direction to form multiple rows of battery cells. Thus, it can stack both single rows of battery cells and multiple rows of battery cells, and improve the battery cell stacking efficiency.

[0013] The battery cell transfer equipment of this utility model, by applying the above-mentioned battery cell stacking device, can not only stack single rows of battery cells, but also stack multiple rows of battery cells, and improve the battery cell stacking efficiency; at the same time, by using an automatic guide vehicle to drive the battery cell stacking device to move, the convenience of battery cell transfer can also be improved.

[0030] The embodiments of this utility model are described in detail below.

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.

[0031] like Figures 1 to 5 As shown, this embodiment provides a battery cell stacking device, including a base 1 and at least two stacking units 2, which are arranged side by side along a first direction. The stacking unit 2 includes a slide 21, a fixed support 22, a movable support 23, and a first locking assembly 24. The slide 21 is slidably disposed on the base 1 along the first direction, the fixed support 22 is fixedly disposed on the slide 21, and the movable support 23 is slidably disposed on the slide 21 along a second direction. The first locking assembly 24 can lock or unlock the movable support 23 from the slide 21. The second direction is perpendicular to the first direction.

[0032] In this embodiment, the cell stacking device places multiple cells 100 on the same slide 21, and the movable support 23 presses the multiple cells 100 against the fixed support 22 along the second direction. Then, the movable support 23 and the slide 21 are locked by the first locking component 24, so that the single row of cells can be stacked. Then, the slides 21 of the multiple stacking units 2 are slid along the first direction, so that the single row of cells on the multiple slides 21 can be stacked along the first direction to form multiple rows of cells. Thus, it is possible to stack both single rows of cells and multiple rows of cells, and improve the stacking efficiency of the cells 100.

[0033] For example, the slide 21 is slidably disposed on the base 1 via the first slide rail 11. The movable support 23 is slidably disposed on the slide 21 via the second slide rail 211.

[0034] Optionally, the base 1 is provided with casters 12, which facilitates the transfer of the battery cell 100 between different workstations and helps to improve production efficiency.

[0035] Optionally, the first locking assembly 24 includes a first connector, a second connector, and an elastic member 243. The first connector is movably disposed on the movable support 23; the second connector is fixed to the slide 21, and the first connector can be inserted into the second connector; the elastic member 243 is configured to apply a force to the first connector to make the first connector and the second connector insert into each other. By inserting the first connector and the second connector into each other, the movable support 23 and the slide 21 can be locked. At the same time, by applying a force to the first connector through the elastic member 243 to make the first connector and the second connector insert into each other, the connection reliability of the first connector and the second connector can be further improved. When it is necessary to move the movable support 23, simply pull the first connector to separate the first connector and the second connector, which is simple, convenient, and low in cost.

[0036] In this embodiment, as Figure 3 and Figure 4 As shown, the first connector is a pin 241, and the second connector is a socket 242. The socket 242 has a socket 2421, and the pin 241 can be inserted into the socket 2421. Of course, in other embodiments, the first connector can be a socket 242, and the second connector can be a pin 241.

[0037] For example, the first connector can be moved along a third direction by an unlocking drive to engage or disengage the first connector from the second connector. The unlocking drive is a linear actuator such as a cylinder.

[0038] Optionally, the first locking assembly 24 further includes a rotating member 244, which is rotatably disposed on the first connector about a first axis; the first axis is parallel to a first direction. Specifically, a wedge-shaped block is provided at the free end of the cylinder piston rod, and the inclined surface of the wedge-shaped block and the second connector are located on opposite sides of the rotating member 244. By driving the wedge-shaped block to move along the second direction through the cylinder, and causing the rotating member 244 to move on the inclined surface of the wedge-shaped block, the first connector and the second connector can be inserted or separated. It should be noted that when the rotating member 244 moves on the inclined surface of the wedge-shaped block, the rotating member 244 can rotate, thereby reducing friction. This not only slows down the wear of the rotating member 244 and the wedge-shaped block, but also improves the smoothness of the movement of the first connector, which is beneficial to extending the service life of the first connector.

[0039] For example, the rotating component 244 is a bearing, such as a deep groove ball bearing.

[0040] Specifically, the elastic element 243 is a spring. The pin 241 has a mounting portion 2411, which is slidably disposed on the movable support member 23 along a third direction. The spring is sleeved on the outside of the mounting portion 2411, with one end connected to the mounting portion 2411 and the other end connected to the movable support member 23. The first direction, the second direction, and the third direction are perpendicular to each other. Optionally, two mounting portions 2411 are provided, spaced apart along the first direction. Two springs are provided, each sleeved on the outside of one of the two mounting portions 2411. The rotating member 244 is connected to both mounting portions 2411 at its two ends along its axial direction.

[0041] Optionally, such as Figure 4 and Figure 5 As shown, the second connector is adjustablely positioned on the slide 21 along the second direction. By adjusting the position of the second connector along the second direction, the fixed position of the movable support 23 can be adjusted, thereby adjusting the clamping force applied to the battery cell 100 by the movable support 23 and the fixed support 22, which is beneficial to improving the versatility of the battery cell stacking device.

[0042] Optionally, the first locking assembly 24 further includes a first fastener, which can lock or unlock the second connector and the slide 21. The second connector has a first elongated hole 2422, and the first fastener passes through the first elongated hole 2422. When the first fastener unlocks the second connector from the slide 21, the first fastener can move along a second direction within the first elongated hole 2422, thereby facilitating the adjustment of the position of the second connector along the second direction. After the position of the second connector is adjusted, the second connector can be locked back to the slide 21 using the first fastener. The operation is simple, convenient, and low-cost.

[0043] For example, the first fastener is a first bolt, the slide 21 is provided with a first threaded hole, the head of the first bolt abuts against the second plug-in, and the shank of the first bolt passes through the first elongated hole 2422 and is threadedly connected to the first threaded hole.

[0044] Furthermore, the stacking unit 2 also includes a first adjustment assembly 25, which includes a first support 251 and a first adjustment rod 252. The first support 251 is fixed to the slide 21, and the first adjustment rod 252 is threadedly connected to the first support 251. The axial direction of the first adjustment rod 252 is parallel to the second direction, and one end of the first adjustment rod 252 is rotatably connected to the second connector. By rotating the first adjustment rod 252, the first adjustment rod 252 can be moved along the second direction, thereby driving the second connector to move along the second direction. This improves the accuracy of the second connector position adjustment, and facilitates precise control of the clamping force applied to the battery cell 100 by the movable support 23 and the fixed support 22.

[0045] Optionally, the fixed support 22 is adjustablely positioned on the slide 21 along the second direction. By adjusting the position of the fixed support 22 along the second direction, different numbers of battery cells 100 can be placed between the movable support 23 and the fixed support 22, thereby improving the versatility of the battery cell stacking device.

[0046] Optionally, the slide 21 is provided with multiple connecting parts arranged sequentially along the second direction, and one of the multiple connecting parts is connected to the fixed support 22. That is to say, by connecting the fixed support 22 to different connecting parts, the position of the fixed support 22 along the second direction can be adjusted, which is convenient to operate.

[0047] Optionally, the stacking unit 2 further includes a second fastener, which can lock or unlock the fixed support 22 and the slide 21. The fixed support 22 has a second elongated hole 221, and the second fastener passes through the second elongated hole 221. When the second fastener unlocks the fixed support 22 and the slide 21, the second fastener can move in the second elongated hole 221 along a second direction, thereby facilitating fine adjustment of the position of the fixed support 22 along the second direction, thereby adjusting the clamping force applied to the cell 100 by the movable support 23 and the fixed support 22. After the position of the second connector is adjusted, the fixed support 22 and the slide 21 can be locked again by the second fastener. The operation is simple, convenient, and low-cost.

[0048] It should be noted that the second fastener can lock or unlock the fixed support member 22 to any of the connecting parts; that is, the second fastener can lock or unlock the fixed support member 22 to different connecting parts. By connecting the fixed support member 22 to different connecting parts, the position of the fixed support member 22 along the second direction can be adjusted significantly. When the fixed support member 22 is connected to one of the connecting parts, by unlocking the fixed support member 22 from that connecting part with the second fastener and moving the second fastener within the second elongated hole 221 along the second direction, the position of the fixed support member 22 along the second direction can be finely adjusted.

[0049] For example, the second fastener is a second bolt, the connecting part is a second threaded hole 212 provided in the slide 21, the head of the second bolt abuts against the fixed support 22, and the shank of the second bolt passes through the second elongated hole 221 and is threadedly connected to the corresponding second threaded hole 212.

[0050] Optionally, the stacking unit 2 further includes a second adjustment assembly 26, which includes a second support 261 and a second adjustment rod 262. The second support 261 is fixed to the slide 21, and the second adjustment rod 262 is threadedly connected to the second support 261. The axial direction of the second adjustment rod 262 is parallel to the second direction, and one end of the second adjustment rod 262 is rotatably connected to the fixed support member 22. By rotating the second adjustment rod 262, the second adjustment rod 262 can be moved along the second direction, thereby driving the fixed support member 22 to move along the second direction. This can improve the accuracy of the position adjustment of the fixed support member 22, and thus facilitate precise control of the clamping force applied to the battery cell 100 by the movable support member 23 and the fixed support member 22.

[0051] Furthermore, the second support 261 is adjustablely positioned on the slide 21 along the second direction, thereby facilitating the movement of the second support 261 along the second direction with the fixed support 22. Furthermore, the second adjustment assembly 26 also includes a third fastener, which can lock or unlock the second support 261 from the slide 21, thereby facilitating the adjustment of the position of the second support 261 along the second direction. Specifically, the third fastener is a third bolt, and by connecting the third bolt to different second threaded holes 212, the position of the second support 261 along the second direction can be adjusted.

[0052] Optionally, the movable support 23 is provided with a first clearance groove 231 on the side facing the fixed support 22; the fixed support 22 is provided with a second clearance groove 222 on the side facing the movable support 23, thereby facilitating the insertion of the handling robot into the first clearance groove 231 and the second clearance groove 222 to clamp the battery cell 100 located between the movable support 23 and the fixed support 22, thereby improving the convenience of battery cell 100 transfer.

[0053] Optionally, the movable support member 23 is provided with a first support portion 232 for contacting the battery cell 100. The first support portion 232 is made of an insulating material, thereby protecting the battery cell 100. For example, the first support portion 232 is a first structural member made of an insulating material such as plastic or wood, and the first structural member is fixedly connected to the movable support member 23. Alternatively, the first support portion 232 can also be an insulating adhesive layer disposed on the outside of the movable support member 23.

[0054] Furthermore, the movable support 23 is made of metal, which can improve the service life of the movable support 23.

[0055] Optionally, the contact area between the first support 232 and the battery cell 100 is S1, and the large surface area of ​​the battery cell 100 is S. The value of S1 / S ranges from 15% to 50%. If S1 is too small, the battery cell 100 will be subjected to excessively concentrated force, which may easily lead to deformation or damage. If S1 is too large, the space of the first clearance groove 231 will be too small, making it inconvenient for the handling robot to operate. By making the value of S1 / S range from 15% to 50%, not only can the contact area between the first support 232 and the battery cell 100 be large enough to protect the battery cell 100, but it also facilitates the operation of the handling robot. It should be noted that the large surface of the battery cell 100 is the outer surface with the largest area among the multiple outer surfaces of the battery cell 100.

[0056] For example, the value of S1 / S can be any value between 15% and 50%, such as 15%, 20%, 25%, 30%, 35%, 40%, 45%, or 50%.

[0057] For example, there are two first support portions 232, which are respectively located on both sides of the first relief groove 231 along the first direction, and S1 is the sum of the contact areas between the two first support portions 232 and the battery cell 100.

[0058] Optionally, the fixing support member 22 is provided with a second support portion 223 for contacting the battery cell 100. The second support portion 223 is made of an insulating material, thereby protecting the battery cell 100. For example, the second support portion 223 is a second structural member made of an insulating material such as plastic or wood, and the second structural member is fixedly connected to the fixing support member 22. Of course, the second support portion 223 can also be an insulating adhesive layer disposed on the outside of the fixing support member 22.

[0059] Furthermore, the fixing support 22 is made of metal, which can improve the service life of the fixing support 22.

[0060] Optionally, the contact area between the second support 223 and the battery cell 100 is S2, the large surface area of ​​the battery cell 100 is S, and the value of S2 / S ranges from 15% to 50%. If S2 is too small, the battery cell 100 will be subjected to excessively concentrated force, which may easily lead to deformation or damage to the battery cell 100. If S2 is too large, the space of the second clearance groove 222 will be too small, making it inconvenient for the handling robot to operate. By making the value of S2 / S range from 15% to 50%, not only can the contact area between the second support 223 and the battery cell 100 be large enough to protect the battery cell 100, but it also facilitates the operation of the handling robot.

[0061] For example, the value of S2 / S can be any value between 15% and 50%, such as 15%, 20%, 25%, 30%, 35%, 40%, 45%, or 50%.

[0062] For example, there are two second support portions 223, which are respectively located on both sides of the second relief groove 222 along the first direction, and S2 is the sum of the contact areas between the two second support portions 223 and the battery cell 100.

[0063] Optionally, the stacking unit 2 further includes a second locking component 27, which can lock or unlock the slide 21 to the base 1. When stacking a single row of cells, the slide 21 can be locked to the base 1 by the second locking component 27, which helps to improve the stress stability of the cell 100 located between the movable support 23 and the fixed support 22.

[0064] Optionally, the second locking assembly 27 includes two limiting members 271, which abut against both sides of the slide 21 along the first direction, thereby preventing the slide 21 from moving on the base 1. For example, the limiting member 271 is a limiting pin. The limiting member 271 is detachably mounted to the base 1 by fasteners such as bolts.

[0065] In this embodiment, only one stacking unit 2 is equipped with the second locking component 27, while the other stacking units 2 are not equipped with the second locking component 27. For ease of description, the slide 21 of the stacking unit 2 equipped with the second locking component 27 is referred to as the fixed slide, and the slide 21 of the stacking unit 2 without the second locking component 27 is referred to as the movable slide. After a single row of cells is stacked, the movable slide is pushed to move along the first direction, and all movable slides move towards the fixed slide, thereby stacking to form multiple rows of cells. Preferably, the stacking unit 2 located in the middle of the base 1 along the first direction is equipped with the second locking component 27, which can shorten the movement path of the movable slide and improve production efficiency.

[0066] For example, the working principle of the cell stacking device in this embodiment is as follows:

[0067] First, the unlocking drive mechanism drives the pin 241 to pull out the socket 2421. Then, the stacking drive mechanism drives the movable support 23 to move along the second direction and away from the fixed support 22. Next, multiple battery cells 100 are placed on the slide 21 and brought against the fixed support 22. The stacking drive mechanism then drives the movable support 23 to move along the second direction and closer to the fixed support 22, thereby pressing the multiple battery cells 100 together to form a single row of battery cells. Finally, the unlocking drive mechanism drives the pin 241 to re-insert into the socket 2421 to fix the movable support 23. For example, the stacking drive mechanism uses a linear actuator such as a cylinder.

[0068] A partition is placed between any two adjacent single-row cells, and adhesive is provided on both sides of the partition. Then, multiple slide blocks 21 are pushed closer to each other along the first direction to bond the two adjacent single-row cells together through the partition, thereby forming multiple rows of cells. Finally, the pin 241 is driven by the unlocking drive to pull out the socket 2421, and the multiple rows of cells are removed by the handling robot.

[0069] like Figure 1 As shown, this embodiment also provides a battery cell transfer device, including the battery cell stacking device and the automated guided vehicle 3 (AGV) as described above. The base 1 is located on the vehicle body of the automated guided vehicle 3, which facilitates the movement of the base 1 by the automated guided vehicle 3 and improves the convenience of battery cell 100 transfer.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
