[0024] Example 1 like Figures 1-3As shown, this embodiment provides a battery cell passivation carrier 100, which includes a frame assembly 1, a clamping assembly 2, and at least two lifting support plates 3. The frame assembly 1 includes a base plate 11, a back plate 13, at least one partition plate 14, and two side plates 12. One side plate 12, at least one partition plate 14, and the other side plate 12 are sequentially and spaced apart on the base plate 11 along a first direction. The back plate 13 is connected to one side of the base plate 11, partition plate 14, and side plate 12 along a second direction. The clamping assembly 2 is detachably connected to the two support plates 3. The top of the side plate 12; the frame assembly 1 and the clamping assembly 2 form at least two first receiving cavities 15 spaced apart along a first direction. Adjacent first receiving cavities 15 are separated by a partition 14. The first receiving cavity 15 is used to receive the battery cell pack. The side of the first receiving cavity 15 opposite to the back plate 13 is provided with an opening for passivation of the battery cell pack. The clamping assembly 2 is used to press against the top of the battery cell pack. The lifting plate 3 corresponds one-to-one with the first receiving cavity 15 and is disposed in the first receiving cavity 15. The lifting plate 3 is used to support the battery cell pack. In this embodiment, the first direction is X, the second direction is Y, the first direction and the second direction are perpendicular to each other and both are located in the horizontal plane. The battery cell pack can be composed of multiple stacked battery cells.
[0025] When passivation processing of the battery cell assembly is required, the clamping assembly 2 is disassembled, allowing the battery cell assembly to be installed onto the lifting support plate 3 within the first receiving cavity 15 through the top or front opening of the first receiving cavity 15. Then, the clamping assembly 2 is installed on the top of the two side plates 12, at which point the clamping assembly 2 presses against the top of the battery cell assembly, thus enabling the battery cell assembly to be installed in the battery cell passivation carrier 100. During passivation, passivating gas can passivate the battery cell assembly through the opening of the first receiving cavity 15. This battery cell passivation carrier 100 uses at least two first receiving cavities 15 to support the battery cell assembly, saving space, increasing the load capacity of the battery cell assembly, and thus improving processing efficiency. Furthermore, it adopts a frame structure, which is high-strength, simple in structure, and reduces design difficulty. In this embodiment, there is one partition plate 14, forming two first receiving cavities 15.
[0026] It should be noted that during the installation of the battery cell pack into the first receiving cavity 15, the conveying mechanism transports the battery cells to the first receiving cavity 15. The conveying mechanism has certain requirements for the receiving height. The robotic arm can drive the lifting pallet 3 to rise and fall to meet the receiving height requirements of the conveying mechanism, thus realizing the automated conveying of the battery cells. In this embodiment, the bottom of the lifting pallet 3 is provided with a first clearance groove for the robotic arm to lift.
[0027] Preferably, the side of the partition 14 facing away from the back plate 13 is provided with marking scale 141. The operator can know the number of cells in the cell pack through the marking scale 141, which improves the convenience of processing.
[0028] In this embodiment, hooks 121 are provided on the opposite sides of the two side plates 12. The robotic arm can hook the hooks 121 on the two side plates 12, which facilitates the movement of the battery cell passivation carrier 100.
[0029] Furthermore, the clamping assembly 2 includes a support plate 21, at least two pressure plates 22, and multiple elastic components 23. The support plate 21 is detachably connected to the top of the two side plates 12. The pressure plates 22 are located within the first receiving cavity 15 and below the support plate 21, with each pressure plate 22 corresponding to one of the first receiving cavities 15. The pressure plates 22 are connected to the support plate 21 via multiple elastic components 23, and the elastic force of the multiple elastic components 23 drives the pressure plates 22 to press against the top of the battery cell assembly. The connection between the support plate 21 and the pressure plates 22 is achieved through the elastic components 23, and the elastic force of the multiple elastic components 23 drives the pressure plates 22 to elastically press against the top of the battery cell assembly, thus clamping the battery cell assembly while preventing damage to the battery cell assembly from hard contact between the pressure plates 22 and the battery cell assembly.
[0030] In this embodiment, the bottom ends of the partition 14 and the two side plates 12 are connected to the bottom plate 11 by screws, the support plate 21 is connected to the top ends of the partition 14 and the two side plates 12 by screws, and the back plate 13 is connected to the bottom plate 11, the partition 14, the side plates 12 and the support plate 21 on one side along the second direction by screws. The support plate 21, the side plates 12, the partition 14, the bottom plate 11 and the back plate 13 form a fixed frame, which reduces the number of moving parts and reduces the processing cost of the cell passivation carrier 100.
[0031] In this embodiment, the elastic component 23 includes a bolt 231 and a spring 232. The support plate 21 is provided with a first through hole, and the pressure plate 22 is provided with a first threaded hole. The bolt 231 passes through the first through hole, and the spring 232 is threadedly connected to the first threaded hole. When the pressure plate 22 is not pressed, the spring 232 drives the pressure plate 22 to move away from the support plate 21, and the bolt 231 connects the pressure plate 22 to the support plate 21. When the pressure plate 22 presses against the battery pack, the battery pack drives the pressure plate 22 to compress the spring 232 and move closer to the support plate 21.
[0032] Preferably, such as Figure 1 and Figure 4 As shown, the clamping assembly 2 also includes a pull rod 25 and multiple connectors 26. The pull rod 25 is connected to all bolts 231 via the connectors 26. When unloading the battery cell pack, the robotic arm lifts the pull rod 25 to raise the pressure plate 22, allowing the battery cell pack to be removed from the openings of the two first receiving cavities 15. This operation is convenient, reduces structural complexity and maintenance costs, and features a simple structural logic with few control points, facilitating automated control. Conversely, when installing the battery cell pack, the robotic arm lifts the pull rod 25 to raise the pressure plate 22, facilitating the placement of the battery cell pack through the openings into the two first receiving cavities 15.
[0033] Furthermore, multiple connectors 26 are spaced apart along the first direction, and two first connecting holes 261 are spaced apart along the second direction. The first connecting holes 261 correspond one-to-one with the elastic components 23. Bolts 231 pass through the first connecting holes 261, the first through holes, and the springs 232 and are threaded into the first threaded holes, thus realizing the connection between the connectors 26 and the elastic components 23. Flanges 262 are provided on both sides of the connectors 26 along the first direction. The flanges 262 are located in the middle position of the connectors 26 along the second direction. The flanges 262 are provided with second connecting holes 263. The pull rods 25 extend along the second direction and pass through the second connecting holes 263 of the multiple connectors 26 in sequence. In this embodiment, the clamping assembly 2 includes four connectors 26 and eight elastic components 23. Each pressure plate 22 corresponds to two connectors 26 and four elastic components 23. The elastic components 23 are connected to the pull rod 25 through the connectors 26. The pull rod 25 is equipped with elastic retaining rings. The two elastic retaining rings abut against the opposite sides of the flanges 262 located at both ends in the first direction, which can prevent the pull rod 25 from moving relative to the connectors 26 in the first direction.
[0034] It should be noted that, as Figure 5 and Figure 6 As shown, this embodiment also provides a boat support 200, which is used to accommodate the battery cell passivation carrier 100. The boat support 200 is provided with a plurality of second accommodating cavities, and the plurality of battery cell passivation carriers 100 can be arranged side by side in the second accommodating cavities in a horizontal or vertical manner.
[0035] Preferably, such as Figure 2 As shown, the bottom wall of the base plate 11 is provided with a base plate positioning groove 111. When the base plate 11 is installed in the second receiving cavity, a positioning post is provided at the bottom of the second receiving cavity. The positioning post extends into the base plate positioning groove 111, improving the installation accuracy of the battery cell passivation carrier 100. And / or the bottom wall of the base plate 11 is provided with a support plate positioning hole 112. The bottom of the lifting support plate 3 is provided with a positioning protrusion. The positioning protrusion can be embedded in the support plate positioning hole 112, improving the stability of the lifting support plate 3 and limiting the horizontal displacement of the lifting support plate 3. And / or the bottom wall of the base plate 11 is provided with a QR code mounting groove 113, and the QR code can be pasted into the QR code mounting groove 113. In this embodiment, the bottom wall of the base plate 11 is provided with a base plate positioning groove 111, a support plate positioning hole 112, and a QR code mounting groove 113.
[0036] Example 2 like Figure 7 and Figure 8 As shown, this embodiment also provides a battery cell passivation carrier 100. The structure of the battery cell passivation carrier 100 provided in this embodiment is basically the same as that in Embodiment 1, except that the structure of the clamping component 2 is partially different. This embodiment will not describe the structure that is the same as that in Embodiment 1.
[0037] In this embodiment, the battery cell passivation carrier 100 further includes two snap-fit components 24. The two ends of the support plate 21 are snapped to the top ends of the two side plates 12 by the snap-fit components 24 respectively. The two ends of the support plate 21 overlap the top ends of the two side plates 12. The snap-fit component 24 includes a fixing block 241 and a snap-fit block 242. The fixing block 241 is connected to the side plate 12. The fixing block 241 is provided with a guide hole 2411 extending in the first direction. The snap-fit block 242 is slidably connected in the guide hole 2411. The snap-fit block 242 can slide to the snap-fit position and the avoidance position. When the snap-fit block 242 is in the snap-fit position, the snap-fit block 242 stops the end of the support plate 21 from the side plate 12. When the snap-fit block 242 is in the avoidance position, the support plate 21 can be disengaged from the side plate 12. When installing the clamping assembly 2, first slide the snap-fit block 242 to the clearance position, then overlap the two ends of the support plate 21 with the tops of the two side plates 12, and then push the snap-fit block 242 to the snap-fit position. The snap-fit block 242 stops the end of the support plate 21 away from the side plate 12, thus fixing the support plate 21. In this embodiment, each fixing block 241 is provided with two guide holes 2411 spaced apart along the second direction, so the two ends of the support plate 21 are fixed by two snap-fit blocks 242 respectively.
[0038] More preferably, the support plate 21 is provided with second clearance grooves 213 on both sides along the second direction, and grippers 212 are provided in the second clearance grooves 213. By providing the second clearance grooves 213, the distance between the grippers 212 on both sides of the support plate 21 can be reduced, thereby meeting the gripping width requirements of the robot arm. When it is necessary to disassemble or assemble the clamping assembly 2, the robot arm can grip the grippers 212 on both sides of the support plate 21, making it easy to move the clamping assembly 2.
[0039] More preferably, the bottom wall of the snap-fit block 242 near the support plate 21 is provided with a buckle, and the support plate 21 is provided with a slot 211 corresponding to the buckle, so that the buckle can snap into the slot 211. On the one hand, when the support plate 21 is snapped in place, the snap-fit block 242 is prevented from continuing to slide along the guide hole 2411, thereby improving the stability of the connection; on the other hand, the buckle of the support plate 21 can prevent the snap-fit block 242 from moving too far away from the support plate 21.
[0040] Preferably, the snap-fit component 24 includes a limiting washer 243 and a fastening screw 244. A second threaded hole is provided at the end of the snap-fit block 242 facing away from the support plate 21. The fastening screw 244 passes through the limiting washer 243 and is threaded into the second threaded hole. The limiting washer 243 prevents the snap-fit block 242 from moving too far in the direction close to the support plate 21. The snap-fit and limiting washer 243 limit the movement of both ends of the snap-fit block 242, preventing the snap-fit block 242 from disengaging from the guide hole 2411.
[0041] The cell passivation carrier 100 in this embodiment has a stable structure and simple motion logic. The support plate 21 is connected to the side plate 12 by a snap-fit method. It is automatically closed by a mechanical device. When the snap-fit is opened, the cells can be automatically picked up and put in from the top without changing the placement angle of the cell passivation carrier 100, which can reduce the difficulty and cost of automation design.
[0042] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. 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. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
