Description

Technical Field

[0001] This utility model relates to the field of battery formation equipment technology, and in particular to a wire harness follow-up formation fixture. Background Technology

[0002] The formation process is one of the core steps in lithium battery manufacturing. It uses formation equipment to charge and discharge the battery cell to activate the active materials inside the cell and form a stable SEI film (Solid Electrolyte Interphase), thereby improving the battery's performance and safety.

[0003] During the cell formation process, the cells need to be clamped using a formation fixture to achieve formation under high pressure, while continuously charging and discharging them. Therefore, in the pressure fixture of the formation equipment, the layers need to be connected to wiring harnesses to charge and discharge the cells fixed to the layers. However, as the layers slide with the cells, the wiring harnesses can interfere with and rub against other components, causing deviations in the actual displacement of the layers or the applied pressure, thus affecting the cell formation effect and degrading battery performance and safety. Therefore, existing formation fixtures require further optimization. Utility Model Content

To this end, this invention proposes a wire harness follow-up formation fixture, which can avoid interference and friction between the wire harness and other wire harnesses or components during the battery cell formation process, thus preventing a deterioration in the battery cell formation effect and ensuring a good battery cell formation result.

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.

[0031] 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.

[0032] 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.

[0033] The following is for reference. Figures 1 to 6 This invention describes a wire harness follow-up forming fixture provided according to an embodiment of the present invention.

[0034] like Figures 1 to 3 As shown, the wire harness follow-up formation fixture according to this embodiment of the present invention can be applied in formation equipment to apply an effective clamping action to the battery cell to be formed, facilitating the formation process of the battery cell. The wire harness follow-up formation fixture of this embodiment can effectively prevent interference and friction between the wire harness and other wire harnesses or components during the battery cell formation process, thereby preventing a deterioration in the battery cell formation effect and ensuring high battery manufacturing quality.

[0035] The wire harness follower-type formation fixture has a first direction, a second direction, and a third direction, wherein the first direction, the second direction, and the third direction are arranged perpendicularly to each other. In this embodiment, it is assumed that the first direction is the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction.

[0036] The structure of the wire harness follow-up formation fixture includes a frame 400, a shelf assembly 100, a drive mechanism 200, and a wire harness follow-up assembly 300.

[0037] The rack 400 provides mounting and support positions for the shelf assembly 100, drive mechanism 200, and wire harness follower assembly 300. It is understood that the structure of the rack 400 can be designed according to actual needs and is not specifically limited here. In this embodiment, the rack 400 includes end plates and connecting rods. Two end plates are provided and arranged at certain intervals along a first direction. Multiple connecting rods extending along the first direction are provided between the two end plates, and the opposite ends of each connecting rod are fixedly connected to the two end plates respectively.

[0038] The shelf assembly 100 includes multiple shelves 110, which are arranged at certain intervals along a first direction. The thickness of each shelf 110 extends along the first direction, and the length of each shelf 110 extends along a second direction. All shelves 110 are slidably connected to the frame 400 along the first direction, thus allowing all shelves 110 to move along the first direction, either close together or far apart. It is understood that all shelves 110 can be mounted on the frame 400 via guide rail slider pairs or optical axis guide sleeves, enabling smooth linear movement of the shelves 110. In this embodiment, the shelf 110 is T-shaped when viewed along the first direction. The upper part of the shelf 110 has sliding connection portions at opposite ends along the second direction. Slider or guide sleeves are disposed on the sliding connection portions, and guide rails or optical axes are disposed on the frame 400.

[0039] Furthermore, each shelf 110 is provided with a cell support portion and a wire harness connection end. The cell support portion is located on one side of the shelf 110 along the first direction. Its function is to fix the cell, ensuring its stability and allowing the adjacent shelves 110 to apply a clamping force to the cell. The wire harness connection end can be located on one side of the shelf 110 along the second direction or at the lower end of the shelf 110. The wire harness connection end is equipped with a wire harness for charging and discharging the cell. It is understood that the wire harness connection end can be a wire clamp; one end of the wire harness can be fixed to the shelf 110 by the clamp, and the other end can be electrically connected to a power source, thereby charging the cell located on the cell support portion via the wire harness.

[0040] The drive mechanism 200 is configured to drive all the shelves 110 to move along a first direction and move closer together, so that any two adjacent shelves 110 can clamp the battery cell located on the battery cell carrier. Specifically, the drive mechanism 200 includes a drive assembly and a pusher assembly 240. The pusher assembly 240 is located on one side of the shelf assembly 100 along the first direction. The output end of the drive assembly is connected to the pusher assembly 240. The drive assembly can drive the pusher assembly 240 to move along the first direction toward the shelf assembly 100, so that the pusher assembly 240 can apply a pushing force to all the shelves 110, causing all the shelves 110 to move along the first direction, and all the shelves 110 will move closer together and clamp the battery cell. It is understood that the drive assembly can be a linear drive such as a cylinder, hydraulic cylinder, or electric cylinder.

[0041] The wire harness follower assembly 300 includes a guide rod 310 and a wire threading slider 320. The guide rod 310 extends along a first direction and is fixedly connected to the frame 400. The wire threading slider 320 is slidably connected to the guide rod 310 along the first direction, allowing it to move on the guide rod 310. The wire threading slider 320 has wire holes 321 for the wire harness to pass through, the shape and size of which are designed according to the outer diameter of the wire harness. Multiple wire threading sliders 320 are provided and arranged at intervals along the first direction. All wire threading sliders 320 are arranged in a one-to-one correspondence with all wire harnesses, and each wire harness passes through the wire hole 321 of the corresponding wire threading slider 320.

[0042] Understandably, the wire harness is connected to the layer plate 110 and the wire threading slider 320 respectively. As one end of the wire harness moves with the layer plate 110, the wire harness can apply force to the wire threading slider 320 to drive the wire threading slider 320 to slide on the guide rod 310 as the layer plate 110 moves. This allows the wire harness to move together with the wire threading slider 320, effectively preventing the actual displacement or pressure of the layer plate 110 from shifting due to interference and friction between wire harnesses or between the wire harness and other components, which could lead to poor cell formation.

[0043] In this embodiment, the wire harness follower component 300 is located below the wire harness connection end, and the wire harness follower component 300 and the wire harness connection end are vertically opposite each other. This design can effectively utilize the space below the shelf assembly 100 for wire harness routing, avoiding adverse effects of the wire harness on the operation of the shelf assembly 100, drive mechanism 200, and other components. At the same time, it can also shorten the distance between the wire harness connection end and the threading slider 320, thereby reducing the length of the wire harness located between the threading slider 320 and the wire harness connection end. Therefore, when the shelf 110 moves the wire harness through the wire harness connection end, the wire harness can quickly apply force and drive the threading slider 320 to move linearly with the shelf 110, thereby improving the motion synchronization between the shelf 110 and the threading slider 320, which helps to avoid interference and friction between the wire harness and other wire harnesses or components.

[0044] Specifically, the guide rod 310 is fixedly connected to two end plates of the frame 400 at its opposite ends. The guide rod 310 is provided with a groove 311, which extends along a first direction and has its opening facing downwards. The upper end of the threading slider 320 extends into the groove 311 and is slidably connected to the groove 311 along the first direction. The lower end of the threading slider 320 is provided with a wire hole 321, the central axis of which extends along the first direction. In this embodiment, the threading slider 320 is cylindrical and stepped, and a circular ring is connected to the lower end of the threading slider 320. The circular ring has a wire hole 321.

[0045] It is understood that in other embodiments, the wire harness follower assembly 300 may be located on one side of the shelf 110 along the second direction and disposed near the wire harness connection end. The groove 311 may be disposed on one side of the guide rod 310 along the second direction. Furthermore, the wire threading slider 320 is mounted on the guide rod 310 by a sleeve, allowing the wire threading slider 320 to move along the extension direction of the guide rod 310. The guide rod 310 may be a round rod or a square rod; alternatively, the wire threading slider 320 may have a groove 311, and the guide rod 310 may have a guide rail portion, which is adapted to and connected to the groove 311, enabling the wire threading slider 320 to move linearly along the guide rod 310. Figure 1 and Figure 2 As shown, multiple wire harness follow-up forming fixtures can be provided and arranged sequentially along the second direction.

[0046] When using the wire harness follow-up formation fixture provided in this embodiment of the present invention, since a wire harness follow-up component 300 is added to the frame 400, each wire threading slider 320 in the wire harness follow-up component 300 can move along the first direction on the guide rod 310. Each wire threading slider 320 is provided with a wire hole 321 to facilitate the wire harness passing through. Therefore, when the drive mechanism 200 drives all the layers 110 to move along the first direction and squeeze each other, the cell can be subjected to the clamping action from the two adjacent layers 110 to achieve the cell formation process under high pressure clamping action. At the same time, each wire threading slider 320 can drive the corresponding wire harness to move along the guide rod 310 as the layer 110 moves, thereby avoiding the influence of interference friction between the wire harness and other wire harnesses or components, thus ensuring a good cell formation effect and making the manufactured battery have excellent performance and safety.

[0047] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the drive assembly includes a rotary drive and screws 230. At least two screws 230 are provided, each extending along a first direction. The opposite ends of the screws 230 are mounted via bearings, enabling a rotatable connection between the screws 230 and the frame 400, allowing the screws 230 to rotate about their central axis on the frame 400. A pusher assembly 240 is located on one side of the shelf assembly 100 along the first direction and has threaded holes to allow threaded connection between the pusher assembly 240 and all the screws 230. The rotary drive is configured to drive all the screws 230 to rotate, thereby causing the pusher assembly 240 to push all the shelves 110 together along the first direction.

[0048] In this embodiment, there are four screws 230, which are arranged corresponding to the four corners of the pusher assembly 240. The rotary drive includes a motor 210, a gear transmission assembly 220, a drive wheel, and a transmission wheel. One end of each screw 230 is coaxially equipped with a transmission wheel. The motor 210 can be connected to the drive wheel via a reducer. Gear transmission assemblies 220 are provided on opposite sides of the drive wheel along the second direction, and the gear transmission assemblies 220 are meshed with the drive wheel and the transmission wheel, respectively. It is understood that each gear transmission assembly 220 includes at least one gear. When the motor 210 operates and drives the drive wheel to rotate, the two gear transmission assemblies 220 rotate simultaneously, driving the transmission wheel to rotate the screws 230. At this time, all the screws 230 rotate in the same direction, allowing the pusher assembly 240 to move stably along the first direction.

[0049] Specifically, the pusher assembly 240 includes a first pusher plate, a spring, a second pusher plate, a sliding seat, and a pressure sensor 250. The sliding seat is threadedly connected to a screw 230. The first and second pusher plates are arranged at intervals along a first direction. Multiple springs are provided between the first and second pusher plates, with each spring's opposite ends fixedly connected to the first and second pusher plates, respectively. The first pusher plate has a guide shaft extending along the first direction. Both the second pusher plate and the sliding seat have guide sleeves adapted to and connected to the guide shaft. One end of the guide shaft has a limiting block located on the side of the sliding seat away from the second pusher plate. The first pusher plate is positioned close to the shelf assembly 100, and the second pusher plate is located between the first pusher plate and the sliding seat. The pressure sensor 250 is mounted on the sliding seat and located between the second pusher plate and the sliding seat. The second pusher plate can contact the pressure sensor 250, causing the pressure sensor 250 to generate a detection signal.

[0050] When the screw 230 rotates, the sliding seat can move along the first direction and push the second push plate and the first push plate toward the shelf assembly 100. At this time, the second push plate abuts against the pressure sensor 250, and the first push plate abuts against the shelf 110. During the process of the first push plate pushing all the shelf 110 to squeeze each other and clamp the battery cell, as the sliding seat continues to move, the sliding seat and the second push plate can move relative to the first push plate along the guide shaft, so that the spring is compressed, thereby increasing the pushing force of the first push plate on the shelf assembly 100, thereby increasing the clamping effect on the battery cell. At this time, the force data is obtained through the pressure sensor 250. When the force data reaches the set value, the drive mechanism 200 stops working, so that the sliding seat stops moving and avoids the battery cell being subjected to excessive clamping force.

[0051] In some embodiments, each screw 230 is provided with a first threaded section 231 and a second threaded section 232, which are arranged along the extension direction of the screw 230, and the thread direction of the first threaded section 231 and the thread direction of the second threaded section 232 are opposite. Two pusher plate assemblies 240 are provided, and the two pusher plate assemblies 240 are respectively located on opposite sides of the shelf assembly 100 along a first direction, and the two pusher plate assemblies 240 are symmetrically arranged about the shelf assembly 100. One of the two pusher plate assemblies 240 is threadedly connected to the first threaded section 231, and the other is threadedly connected to the second threaded section 232.

[0052] When the screw 230 rotates in the forward direction, the two pusher assemblies 240 can move along the extension direction of the screw 230 and approach each other, causing the shelf assembly 100 to be pushed by the two pusher assemblies 240, causing the shelves 110 to press against each other to clamp the battery cell. When the screw 230 rotates in the reverse direction, the two pusher assemblies 240 can move along the extension direction of the screw 230 and move away from each other, thereby removing the pushing force of the pusher assemblies 240 on the shelf assembly 100 and facilitating the removal of the battery cell from the shelf assembly 100. This design reduces the travel of the pusher assemblies 240, further reduces material damage caused by friction, and improves the movement accuracy of the pusher assemblies 240 and the shelf assembly 100, as well as the pressure accuracy of the battery cell.

[0053] It is understandable that, in the case of two pusher assemblies 240, two drive mechanisms 200 can also be used to drive the two pusher assemblies 240 to move respectively.

[0054] In some embodiments, such as Figure 4 As shown, each shelf 110 has guide sliders 261 at opposite ends along the second direction, and the frame 400 has slide rails 263 extending along the first direction. Two slide rails 263 are provided, and they are arranged at a certain interval along the second direction. The slide rails 263 and guide sliders 261 are slidably connected along the first direction. The guide sliders 261 can be positioned on the upper side of the slide rails 263. Through the sliding engagement of the guide sliders 261 and the slide rails 263, the shelf 110 can move smoothly relative to the frame 400 along the first direction, reducing friction on the shelf 110 during movement and avoiding the wear problem caused by the sleeve sliding engagement method used in the prior art for the shelf 110.

[0055] Furthermore, a first spring 262 is provided between any two adjacent guide sliders 261. The first spring 262 is capable of extending and retracting in a first direction, and its opposite ends are fixedly connected to the two guide sliders 261. Before the pusher assembly 240 begins to apply a pushing force to the shelf assembly 100, the first spring 262 can be in its natural state, and the spacing between all the shelves 110 is consistent.

[0056] When all the shelves 110 are pressed against each other along the first direction by the pusher assembly 240, any two adjacent guide sliders 261 will move closer to each other. At this time, the first spring 262 can act as a buffer to prevent strong collisions between the shelves 110. When the pusher assembly 240 moves away from the shelf assembly 100 along the first direction, the first spring 262 can apply a spring force to the guide slider 261, causing the guide slider 261 to move the corresponding shelf 110 along the first direction, causing the shelves 110 to move away from each other, so that the shelf assembly 100 returns to its original state, thereby realizing the automatic reset of the shelves 110, which facilitates the loading and unloading of battery cells by the staff. It is understandable that without the first spring 262, the reset of the shelves 110 would need to be achieved manually.

[0057] In some embodiments, such as Figure 5 As shown, the battery cell support section is provided with a conductive sheet 151, which is used to electrically connect with the battery cell to energize it. Furthermore, in any two adjacent layers 110, one of them is provided with a roller drive component 156, and the other is provided with a roller 153, a support 154, and a probe assembly 152.

[0058] The roller 153 can be mounted on the support 154 via a rotating shaft, allowing the roller 153 to be rotatably connected to the support 154. The support 154 is elastically connected to the shelf 110. Specifically, the support 154 is slidably connected to the shelf 110 via a guide rail slider pair, and a second spring 155 is provided between the support 154 and the shelf 110. The probe assembly 152 is fixedly connected to the support 154 by bolts, and the probe assembly 152 is arranged opposite to the guide plate, enabling the probe assembly 152 to be electrically connected to the wire harness. The roller transmission component 156 has a guide slope, the inclination direction of which forms an angle with the movement direction of the shelf 110. The guide slope guides the movement of the roller 153, causing the roller 153 to drive the support 154 and the probe assembly 152 to move closer to the conductive plate 151.

[0059] The central axis of roller 153 is perpendicular to the direction of movement of shelf 110 and the direction of extension and retraction of second spring 155. Roller 153 is configured to move along guide ramp when the two shelves 110 come together, and drive support 154 to move probe assembly 152 toward conductive sheet 151 so that probe assembly 152 makes conductive contact with conductive sheet 151.

[0060] In this embodiment, the conductive sheet 151 is located on one side of the battery cell support portion along the second direction, the probe assembly 152 is arranged opposite to the conductive sheet 151 in the second direction, the support 154 and the roller transmission component 156 are arranged on the same side of the same layer plate 110 along the second direction, the support 154 can move relative to the layer plate 110 in the second direction, the second spring 155 can extend and retract in the second direction, and the central axis of the roller 153 extends in the vertical direction.

[0061] During the process of any two adjacent shelves 110 moving closer to each other, the roller drive 156 on one shelf 110 and the roller 153 on the other shelf 110 move closer to each other along the first direction. At this time, the roller 153 can roll along the guide slope of the roller drive 156, causing the roller 153 to move along the second direction towards the shelf 110 with the support 154 and the probe assembly 152, so that the probe assembly 152 can abut against the conductive sheet 151, ensuring that there is electrical conductivity between the probe assembly 152 and the conductive sheet 151, so that the battery cell on the battery cell carrier can be energized. At the same time, the second spring 155 is in a compressed state.

[0062] During the process of any two adjacent shelves 110 moving away from each other, the roller drive 156 and the roller 153 move away from each other along the first direction. At this time, under the elastic force of the second spring 155, the roller 153 abuts against the guide slope and rolls along the guide slope. At the same time, the support 154 drives the probe assembly 152 to move away from the shelf 110 along the second direction, causing the probe assembly 152 to separate from the conductive sheet 151.

[0063] It is understandable that with the above-described structural configuration, when the shelves 110 move closer or further apart, the probe assembly 152 automatically moves closer or further away from the conductive sheet 151 through the cooperation of the roller transmission component 156, roller 153, support 154, and second spring 155. This allows control of the power supply to the battery cell without the need for an additional drive component to move the probe assembly 152, thus saving costs and simplifying the control strategy. Moreover, with the screw 230 having a first threaded section 231 and a second threaded section 232, and all screws 230 being driven to rotate by the same rotary drive component, the above-described method allows for simultaneous operation of the shelf assembly 100 clamping the battery cell and the conductive connection between the probe assembly 152 and the conductive sheet 151 through the energization of a single rotary drive component.

[0064] The roller drive component 156 can be made of metal such as iron, and its structure and shape are not limited, as long as it can provide a guide slope that cooperates with the roller 153. Of course, it is not excluded that the roller 153 is fixed relative to the support 154; the support and the roller drive component 156 are located on opposite sides of the same shelf 110 along the second direction; the conductive sheet 151 and the probe assembly 152 are located on one side of the shelf 110 along the vertical direction.

[0065] In some embodiments, such as Figure 5 and Figure 6 As shown, the battery cell carrier is detachably connected to one side of the shelf 110 along the first direction, for example, by means of bolt connection or snap-fit ​​connection. Therefore, the battery cell carrier, along with the battery cell, can be placed on the shelf 110.

[0066] Specifically, the structure of the battery cell support includes a base 120, a fixing component 130, a pressure plate 170, and a flexible gasket 140. The conductive sheet 151 can be fixed to the base 120 with screws. The fixing component 130 is located on the base 120 and is electrically connected to the conductive sheet 151. The fixing component 130 is configured to fix and supply power to the battery cell.

[0067] In one specific embodiment, the base 120 is plate-shaped and can be in contact with the shelf 110. The fixing assembly 130 includes a limiting block, a first clamping block, a second clamping block, a first elastic member, and a second elastic member. The limiting block is L-shaped and fixed to the surface of the base 120 along a first direction. The first clamping block is located above the limiting block and can be slidably connected to the base 120 in the vertical direction via a guide rail slider pair. The first elastic member can extend and retract in the vertical direction, and its opposite ends are respectively connected to the first clamping block and the base 120. The second clamping block is located on one side of the limiting block along a second direction and can also be slidably connected to the base 120 in the second direction via a guide rail slider pair. The second elastic member can extend and retract in the second direction, and its opposite ends are respectively connected to the second clamping block and the base 120. The first and second elastic members are springs. The surface of the base 120, the limiting block, the first clamping block, and the second clamping block together form a receiving groove for clamping and fixing the battery cell.

[0068] Understandably, after the battery cell is placed in the receiving slot, the elastic force of the first and second elastic elements causes the first and second clamping blocks to cooperate with the limiting block, stably clamping the battery cell. The first clamping block, the second clamping block, or the limiting block is equipped with conductive elements, which can be electrically connected to the conductive sheet 151 via wires or the like. Therefore, after the probe assembly 152 contacts the conductive sheet 151, the battery cell can be charged through the conductive elements. Of course, the fixing assembly 130 can also employ other structures capable of fixing the battery cell.

[0069] A flexible gasket 140 protrudes from the surface of the pressure plate 170 along a first direction. The base 120, the fixing component 130, the flexible gasket 140, and the pressure plate 170 are arranged sequentially along the first direction. Furthermore, a clamping space conforming to the shape of the battery cell is formed between the flexible gasket 140 and the surface of the fixing component 130 that contacts the battery cell. For example, if the battery cell is curved, the shape of the clamping space is adapted to the curved battery cell. The flexible gasket 140 has a certain elastic deformation capability to avoid damage to the battery cell due to rigid contact. The flexible gasket 140 can be made of flexible graphite. The pressure plate 170 is configured to press the flexible gasket 140 against the fixing component 130 when any two adjacent layers 110 come together.

[0070] It is understandable that, given the small size of some consumer battery cells, to ensure the cells can withstand precise pressure output, they cannot be placed directly on the large-area shelf 110. Furthermore, for some irregularly shaped cells, such as curved cells, direct pressure application through the shelf assembly 100 can easily damage them. Therefore, this embodiment adds a fixing assembly 130, a flexible pad 140, and a pressure plate 170 to the base 120. The fixing assembly 130 secures the cells. When any two adjacent shelves 110 come close together, the pressure plate 170 receives a pushing force from the shelves 110, causing it to move in the first direction. This, in conjunction with the base 120 and the flexible pad 140, applies pressure to the cells. The flexible pad 140 provides uniform pressure to the cells, ensuring that the pressure is concentrated at the cell location. Moreover, the flexible pad 140 and the fixing assembly 130 can be adjusted to accommodate the pressure of cells of different specifications.

[0071] In some embodiments, such as Figures 4 to 6 As shown, the shelf 110 is provided with a support portion 111, which is used to support the battery cell carrier portion. The support portion 111 and the shelf 110 can be an integral structure or connected by bolts.

[0072] The upper surface of the support portion 111 is provided with a locking part, and the lower surface of the base 120 is provided with a locking groove. The locking part and the locking groove are adapted to each other. In this embodiment, the support portion 111 is provided with an upward-opening limiting groove. The limiting groove is an isosceles trapezoid when viewed along the first direction. The bottom of the limiting groove protrudes upward to form a locking part. The lower end of the base 120 is adapted to the limiting groove, and the lower surface of the base 120 is recessed to form a locking groove. Therefore, the base 120 can be placed in the limiting groove from top to bottom, and the locking part and the locking groove are fitted together, preventing the base 120 from moving on the horizontal plane. Moreover, the lower end of the pressure plate 170 is also adapted to the limiting groove. The pressure plate 170 can move along the first direction within the limiting groove, but cannot move along the second direction. Therefore, when the shelf assemblies 100 are pressed against each other, the pressure plate 170 can move closer to the base 120 along the first direction.

[0073] This design facilitates the removal and removal of the discharge core carrier section via a robotic arm or manual operation in the vertical direction. Alternatively, the lower surface of the base 120 may have a locking part, and the upper surface of the support 111 may have a locking groove.

[0074] Furthermore, such as Figure 5 and Figure 6 As shown, the base 120 is provided with guide posts 121, which extend along a first direction. The number of guide posts 121 is not limited to one. The pressure plate 170 is provided with guide holes 171, which extend through along the first direction. The guide holes 171 and guide posts 121 are arranged in a one-to-one correspondence and are adapted to each other. In this embodiment, there are four guide posts 121, which are respectively arranged at the four corners of the base 120. There are also four guide holes 171, which are respectively arranged at the four corners of the pressure plate 170.

[0075] Understandably, after the base 120 and pressure plate 170 are placed on the support portion 111 of the shelf 110, the guide post 121 extends into the guide hole 171, and the outer peripheral surface of the guide post 121 is in contact with the inner peripheral surface of the guide hole 171. When pressurizing the battery cell, the pressure plate 170 can move more precisely along a preset trajectory (i.e., the first direction) with the cooperation of the guide post 121 and the guide hole 171, so that the flexible pad 140 can be pushed by the pressure plate 170 in the first direction, allowing the flexible pad 140 to apply uniform pressure to the battery cell. Of course, it is also possible that the pressure plate 170 is provided with the guide post 121 and the base 120 is provided with the guide hole 171.

[0076] Furthermore, such as Figure 5 and Figure 6 As shown, the battery cell carrier also includes a magnetic attraction component, which is disposed between the base 120 and the pressure plate 170 so that the base 120 and the pressure plate 170 are in close contact.

[0077] Specifically, the magnetic attraction assembly includes a first connector and a second connector. The first and second connectors can be two magnets 160, or a magnet 160 and an iron block, respectively. The first connector can be mounted on the base 120 with screws, and the second connector is fixedly connected to the pressure plate 170. The first and second connectors are arranged opposite each other along a first direction and can be magnetically connected. The number of magnetic attraction assemblies is not limited to one. When multiple magnetic attraction assemblies are provided, all magnetic attraction assemblies can be arranged in a matrix.

[0078] Understandably, based on production process requirements, external transfer equipment such as overhead cranes or robotic arms can be used to remove the battery cell carrier from the shelf 110. By setting up a magnetic attraction component, the base 120 and the pressure plate 170 are magnetically attached to each other, thus preventing the relative positions of the pressure plate 170 and the base 120 from easily shifting during the transfer process. Furthermore, utilizing the magnetic attraction, the transfer equipment can grasp at least one of the pressure plate 170 and the base 120, thereby achieving the transfer of the battery cell carrier. Moreover, during the transfer process, the base 120 and the pressure plate 170 are less likely to detach or separate.

[0079] Of course, a magnetic attraction assembly can also be provided between the base 120 and the shelf 110 to make the base 120 and the shelf 110 fit together. After the base 120 is placed on the support part 111, the magnetic attraction assembly can keep the base 120 always in contact with the shelf 110. Therefore, both the base 120 and the pressure plate 170 can be subjected to the compression action of the corresponding shelf 110.
