Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and more specifically, to an automatic battery cell and shell feeding device. Background Technology

[0002] As shown in the figure, the battery cell casing is a hollow cuboid formed by bending an aluminum plate in half upwards. After bending, the two sides of the aluminum plate are welded and fixed.

[0003] Currently, during the loading process of battery cells, each battery cell is manually placed onto a conveyor belt. The conveyor belt then transports the battery cells sequentially to a transfer robot. The transfer robot moves to pick up the battery cells one by one and transfer them to the processing station for processing. After processing, the transfer robot picks them up again and transfers them to another conveyor belt, which then transports them to the next processing station.

[0004] The above-mentioned feeding and transfer methods require repeated picking actions by transfer robots, which wastes a lot of time in the process of picking up and dropping, greatly reducing the feeding and conveying efficiency, and ultimately affecting the overall production efficiency of the battery cell casing. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing battery cell shell feeding is time-consuming and labor-intensive, resulting in low feeding and production efficiency. In order to overcome the above-mentioned defects of the prior art, this utility model provides a method that can stack multiple battery cell shells between the first feeding mechanism and the second feeding mechanism at one time, and realize the feeding drive component to transport each battery cell shell to the core shell conveying mechanism one by one, without the need for manual placement, and at the same time greatly improves the feeding and production efficiency.

[0006] To achieve the purpose of this utility model, the following technical solution is adopted:

[0007] An automatic battery cell casing feeding device includes a frame and a first feeding mechanism and a second feeding mechanism mounted on the frame, wherein the first and second feeding mechanisms are horizontally symmetrical and spaced apart. Each of the first and second feeding mechanisms includes a support base, a limiting frame, and a feeding drive assembly. The support base is mounted on the frame, and the limiting frame is vertically mounted on the support base. The limiting frames on the first and second feeding mechanisms cooperate to limit the two ends of the battery cell casings, causing the battery cell casings to be vertically stacked between the two limiting frames. The feeding drive assembly includes at least one drive module. The drive module includes a... A first telescopic part and a second telescopic part are vertically spaced on the limiting frame, with the first telescopic part located above the second telescopic part. The distance between the first and second telescopic parts is greater than the height of one battery cell shell. When waiting for material, both the first and second telescopic parts are extended, with the first telescopic part inserted into the second-to-last battery cell shell, and the bottom surface of the lowest battery cell shell abutting the top surface of the second telescopic part. When loading material, the first telescopic part is extended and inserted into the second-to-last battery cell shell below; the second telescopic part is retracted, causing the lowest battery cell shell to fall onto the cell shell conveying mechanism. The device uses limiting frames on the first and second feeding mechanisms to easily limit the front and rear ends of the battery cell shells, allowing multiple battery cell shells to be stacked between the two limiting frames. This eliminates the need for manual placement of each battery cell shell onto the conveyor belt, enabling one-time direct placement and facilitating operator operation. Furthermore, the orderly extension and retraction of the first and second telescopic parts on the feeding drive assembly ensures that the stacked battery cell shells are transported one by one from the bottom to the cell shell conveying mechanism for transfer, greatly improving the convenience and efficiency of feeding, and thus enhancing the overall production efficiency of battery cell shells.

[0008] Preferably, a telescopic fixing frame is provided on the lower outer side of the limiting frame; both the first and second telescopic parts are telescopic cylinders, and the cylinder bodies of both the first and second telescopic parts are horizontally fixed on the telescopic fixing frame. Positioning blocks are provided at the ends of the telescopic rods of both the first and second telescopic parts; the positioning blocks on the first and second telescopic parts pass through the limiting frame and extend to the inner side of the limiting frame. Linear movement is achieved through the telescopic cylinders. The extension of the telescopic cylinders supports and limits the battery cell shell, while the retraction of the telescopic cylinders facilitates the descent of the battery cell shell onto the cell shell conveying mechanism for transport, greatly improving the convenience of loading.

[0009] Preferably, the top surface of the positioning block is flat, and the bottom surface of the positioning block is provided with a guide surface that slopes from the outside in and from bottom to top. The flat surface ensures that the battery cell shell is placed horizontally, ensuring stability and flatness during the feeding process; the guide surface facilitates insertion into the battery cell shell when waiting for material, supporting and limiting the battery cell shell, thereby achieving the state of the battery cell shell stacking in the limiting frame.

[0010] Preferably, the inner side of the limiting frame, above the second telescopic part, is provided with a U-shaped groove matching the shape of the battery cell shell, and the limiting frame is provided with a conveying opening for removing the battery cell shell below the second telescopic part. The symmetrically arranged U-shaped grooves on both sides of the limiting frame can match the four corners of the battery cell shell, thereby limiting the battery cell shell and ensuring that the battery cell shells are neatly stacked and do not experience excessive displacement during descent, ensuring the accuracy and stability of the feeding process. The conveying opening facilitates the horizontal removal of the battery cell shell from one side, making it convenient for transfer.

[0011] Preferably, the number of drive modules is two, and the two drive modules are symmetrically arranged on the lower outer surface of the limiting frame and spaced apart. The two drive modules ensure stable support of the battery cell casing, improving stability during the support process, and further ensuring that the battery cell casing remains in a horizontal and stable state.

[0012] Preferably, the inner side of the support base is also provided with vertically distributed lifting drive components; the lifting part of the lifting drive component is provided with a support plate. During loading, the lifting drive component lifts the support plate to abut the bottom surface of the lowest battery cell shell. The lifting drive component achieves lifting and lowering movement in the form of a cylinder. The lifting drive component drives the support plate to rise and abut the bottom surface of the lowest battery cell shell, so that after the second telescopic part retracts, it can support the battery cell shell. Then, the lifting drive component descends to smoothly transfer the battery cell shell to the cell shell conveying mechanism, improving the stability of the loading process and preventing the battery cell shell from falling directly and causing excessive displacement or wear.

[0013] Preferably, the system further includes a core shell conveying mechanism mounted on the frame, located between the first and second feeding mechanisms. The core shell conveying mechanism includes a conveying support, a conveyor belt drive motor, a drive gear, a driven gear, a transmission chain, and several conveying carriers. A conveying gap is provided on the frame between the first and second feeding mechanisms. The outer edge of the conveying support is racetrack-shaped, and the conveying support is mounted on the frame and located within the conveying gap. The conveyor belt drive motor is mounted on one side of the conveying support, and its drive shaft passes through the conveying support and connects to the drive gear. The driven gear is rotatably connected to the other side of the conveying support. The transmission chain is tensioned and connected to the drive gear and the driven gear. Several conveying carriers are arranged at intervals on the transmission chain, enabling the conveying carriers to circulate along the outer edge of the conveying support. The battery cell conveying mechanism achieves transportation through a transmission chain, which enables the conveyor carriers on the transmission chain to circulate and place each battery cell one by one onto each conveyor carrier for transportation. This eliminates the need for manual placement or the need for a robotic arm to grab and pick up the cells back and forth, saving conveying space and greatly improving feeding efficiency, thereby further enhancing the production efficiency of battery cells.

[0014] Preferably, racetrack-shaped slide rails are provided along both the front and rear sides of the conveying bracket; the conveying carrier includes a conveying base and a conveying plate; the conveying base is U-shaped with an opening facing downwards, and includes a first side plate, a second side plate, and a connecting plate; the lower part of the first side plate of the conveying base is fixedly connected to the transmission chain, and the upper part of the first side plate is provided with a first pulley that cooperates with the racetrack-shaped slide rail; the upper part of the second side plate of the conveying base is provided with a second pulley that cooperates with the racetrack-shaped slide rail; the connecting plate is connected between the tops of the first side plate and the second side plate, and the conveying plate is horizontally arranged on the connecting plate, with limiting blocks that cooperate with the battery cell shell on both the front and rear sides of the conveying plate. The U-shaped structure of the conveyor base further enhances the connection strength and support stability, ensuring that the battery cell shell can be placed stably on the conveyor plate and transported smoothly. At the same time, the first and second pulleys, located on both sides of the racetrack-shaped slide rail, ensure the smoothness and fluidity of the conveying, as well as the stability and support during the overall sliding process, further ensuring the stability and accuracy of the entire feeding process.

[0015] Preferably, at least one conveying positioning component is also provided on one side of the conveying bracket; the conveying positioning component includes a positioning drive, a positioning drive swing arm, and a positioning shaft; the positioning drive is disposed on the outer wall of the conveying bracket, and the positioning shaft is rotatably connected to the outer wall of the conveying bracket through two positioning shaft supports; one end of the positioning drive swing arm is rotatably connected to the drive part of the positioning drive, and the other end of the positioning drive swing arm is fixed to the positioning shaft; a plurality of positioning rods are arranged at intervals on the positioning shaft, and a positioning plate is provided on the side plate of the conveying base near the positioning rods; a positioning notch is provided on the positioning plate; a positioning roller that positions and cooperates with the positioning notch is provided at the end of the positioning rod; during positioning, the positioning roller is engaged into the positioning notch by swinging the positioning rod to achieve positioning. The positioning drive component, in the form of a cylinder, can drive the positioning drive swing arm to rotate, thereby causing the positioning rod on the positioning shaft to rotate. When moving a distance of one workstation, the positioning roller on the positioning rod is rotated into the positioning recess, thus ensuring that each movement of the conveyor is precise. This ensures the accuracy of each movement and prevents problems such as failure in battery cell shell processing or conveying due to movement errors. This further ensures the accuracy of movement positioning, thereby ensuring the accuracy of the entire processing.

[0016] Preferably, symmetrical alignment and positioning mechanisms are arranged on both sides of the core shell conveying mechanism on the frame. Each alignment and positioning mechanism includes an alignment and positioning bracket, an alignment and positioning cylinder, and an alignment and positioning plate. The alignment and positioning bracket is vertically arranged on the frame, the alignment and positioning cylinder is horizontally arranged on top of the alignment and positioning bracket, and the alignment and positioning plate is vertically arranged on the telescopic rod of the alignment and positioning cylinder. The two alignment and positioning plates clamp each other to align and position the battery core shell to the designated position. Through the alignment and positioning mechanisms on both sides, after the battery core shell is placed on the conveying carrier, the alignment and positioning plates on both sides move towards and clamp the battery core shell, so that the battery core shell can be accurately placed on the conveying carrier, reducing the processing error caused by displacement during the feeding process, and further ensuring the accuracy of feeding, conveying, and subsequent processing.

[0017] In summary, the advantages of this utility model are that the device can easily limit the front and rear ends of the battery cell shell through the limiting frames on the first and second feeding mechanisms, and allow multiple battery cell shells to be stacked between the two limiting frames. This eliminates the need for manual placement of the battery cell shells one by one onto the conveyor belt, enabling one-time direct placement, which is convenient for operators. Furthermore, the orderly extension and retraction of the first and second telescopic parts on the feeding drive assembly ensures that the stacked battery cell shells are transported one by one from the bottom to the cell shell conveying mechanism for transfer, greatly improving the convenience and efficiency of feeding, and thus improving the overall production efficiency of battery cell shells.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 8As shown, an automatic battery cell casing feeding device includes a frame and a first feeding mechanism 1, a second feeding mechanism 2, a cell casing conveying mechanism 3, and a leveling and positioning mechanism 5 mounted on the frame. The first feeding mechanism 1 and the second feeding mechanism 2 are arranged horizontally symmetrically front to back and spaced apart. Both the first feeding mechanism 1 and the second feeding mechanism 2 include a support base 11, a limiting frame 12, and a feeding drive assembly 13. The support base 11 is fixedly mounted on the frame, and the limiting frame 12 is vertically mounted on the support base 11. The limiting frames 12 on the first feeding mechanism 1 and the second feeding mechanism 2 cooperate to limit the two ends of the battery cell casing 6, enabling the battery cell casing 6 to be placed horizontally and stacked vertically. Stacked between two limiting frames 12; the feeding drive assembly 13 includes at least one drive module; the drive module includes a first telescopic part 131 and a second telescopic part 132 arranged vertically at intervals on the limiting frame 12, with the first telescopic part 131 located above the second telescopic part 132; when waiting for material, both the first telescopic part 131 and the second telescopic part 132 are in an extended state, and the first telescopic part 131 is inserted into the second to last battery cell shell, with the bottom surface of the bottom battery cell shell abutting against the top surface of the second telescopic part 132, which can ensure that multiple stacked battery cell shells 6 are supported, and also facilitate the separation of the bottom two, making it convenient to separate them during the subsequent feeding process. During feeding, the first telescopic part 131 remains in an extended state and continues to be inserted into the second to last battery cell shell 6, thereby ensuring that the second to last and above battery cell shells 6 will not fall off and remain stacked between the two limiting frames 12; the second telescopic part 132 changes from an extended state to a retracted state, allowing the bottom battery cell shell 6 to fall freely onto the cell shell conveying mechanism 3. The device can easily limit the front and rear ends of the battery cell shell 6 through the limiting frames 12 on the first feeding mechanism 1 and the second feeding mechanism 2, and allow multiple battery cell shells 6 to be stacked between the two limiting frames 12. This eliminates the need for manual placement of the battery cell shells 6 one by one onto the conveyor belt, enabling one-time direct placement and facilitating operator operation. Furthermore, the orderly extension and retraction of the first telescopic part 131 and the second telescopic part 132 on the feeding drive assembly 13 ensures that the stacked battery cell shells 6 are transported one by one from the bottom to the cell shell conveying mechanism 3 for transfer, greatly improving the convenience and efficiency of feeding, and thus improving the overall production efficiency of the battery cell shells 6.

[0033] like Figure 2 and Figure 3As shown, the rear side of the upper limit frame 12 of the first feeding mechanism 1 and the front side of the upper limit frame 12 of the second feeding mechanism 2 are both provided with U-shaped grooves 121 that match the shape of the outer edge of the battery cell shell 6. The U-shaped grooves 121 are located above the second telescopic part 132, which can ensure that the battery cell shell 6 is limited during the stacking process. The U-shaped grooves 121 symmetrically arranged on the two limiting frames 12 can match the four corners of the battery cell shell 6, thereby limiting the battery cell shell 6. At the same time, it can also ensure that the battery cell shell 6 is neatly stacked and will not have excessive displacement during the falling process, ensuring the accuracy and stability of the feeding. The first feeding mechanism 1 and the second feeding mechanism 2 are provided with conveying openings 122 for the removal of the battery cell shell 6 below the second telescopic part 132. The conveying openings 122 facilitate the horizontal movement of the battery cell shell 6 out of the limiting frame 12, making it convenient to transfer the battery cell shell 6 and preventing movement interference.

[0034] like Figure 2 and Figure 3 As shown, in this embodiment, there are two drive modules, which are symmetrically arranged on the lower outer wall of the limiting frame 12. The two drive modules correspond to the left and right ends of the battery cell shell 6, providing stable support for the battery cell shell 6 and ensuring it is placed horizontally. The two drive modules ensure stable support of the battery cell shell 6, improving stability during support and further ensuring its horizontal stability. Two telescopic fixing brackets 14 are provided on the lower outer side of the limiting frame 12, spaced apart. Each telescopic fixing bracket 14 is rectangular and has through holes in the left and right directions. One drive module is mounted on each corresponding telescopic fixing bracket 14. Both the first telescopic section 131 and the second telescopic section 132 are telescopic cylinders, and the cylinder bodies of both sections are fixed to the outer arm of the telescopic section fixing frame 14 in a front-to-back direction. Positioning blocks 133 are provided at the ends of the telescopic rods of both sections. The positioning blocks 133 on the first and second telescopic sections 131 and 132 pass inward through the limiting frame 12 and extend to the rear side of the limiting frame 12, thereby supporting and limiting the battery core shell 6 within the U-shaped groove 121, facilitating the stacking of the battery core shell 6. Linear movement is achieved through telescopic cylinders. The extension of the telescopic cylinders supports and limits the battery core shell 6, while the retraction of the cylinders facilitates the descent of the battery core shell 6 onto the core shell conveying mechanism 3 for transport, greatly improving the convenience of loading.

[0035] like Figure 3As shown, the top surface of the positioning insert 133 is a flat surface 134, and the bottom surface of the positioning insert 133 is provided with a guide surface 135 that slopes from the outside in and from bottom to top. The flat surface 134 ensures that the battery cell shell 6 is placed horizontally, ensuring stability and flatness during the feeding process; the guide surface 135 facilitates the oblique insertion into the battery cell shell 6 when waiting for the material, improving the guidance, smoothness and accuracy of the insertion. At the same time, after insertion, it also supports and limits the battery cell shell 6, thereby achieving the state in which the battery cell shell 6 is stacked in the limiting frame 12.

[0036] like Figure 2 and Figure 3 As shown, the inner side of the support base 11 is also provided with vertically distributed lifting drive components 15; a support plate 151 is provided on the lifting part of the lifting drive component 15. During feeding, the lifting drive component 15 lifts the support plate 151 to abut against the bottom surface of the lowest battery cell shell 6. The lifting drive component 15 achieves lifting and moving in the form of a cylinder. The lifting drive component 15 drives the support plate 151 to rise and abut against the bottom surface of the lowest battery cell shell 6, so that after the second telescopic part 132 retracts, it can support the battery cell shell 6. Then, the lifting drive component 15 descends to smoothly transfer the battery cell shell 6 to the cell shell conveying mechanism 3, improving the stability during the feeding process, and also preventing the battery cell shell 6 from falling directly and causing excessive displacement or a certain degree of wear.

[0037] like Figures 4 to 6 As shown, a conveying gap 4 is provided on the frame between the first feeding mechanism 1 and the second feeding mechanism 2; the core shell conveying mechanism 3 is located between the first feeding mechanism 1 and the second feeding mechanism 2, and is located within the conveying gap 4. The core shell conveying mechanism 3 includes a conveying support 31, a conveyor belt drive motor 32, a drive gear 33, a driven gear 34, a transmission chain 35, and several conveying carriers; the outer edge of the conveying support 31 is racetrack-shaped, and the conveying support 31 is arranged on the frame in a left-right direction and located within the conveying gap 4, enabling cyclic conveying in the left-right direction. The conveyor belt drive motor 32 is located on the left side of the conveying support 31, and the drive shaft of the conveyor belt drive motor 32 passes through the conveying support 31 and is connected to the drive gear 33; the driven gear 34 is rotatably connected to the right side of the conveying support 31; the transmission chain 35 is tensioned and connected to the drive gear 33 and the driven gear 34; several conveying carriers are arranged at intervals on the transmission chain 35, and the conveying carriers are cyclically conveyed along the outer edge of the conveying support 31. The core shell conveying mechanism 3 achieves conveying through the transmission chain 35, which enables the conveying carrier on the transmission chain 35 to circulate and thus allows each battery core shell 6 to be placed one by one onto each conveying carrier for conveying. This eliminates the need for manual placement or the need for a robotic arm to grab and pick up the core shells, saving conveying space and greatly improving feeding efficiency, thereby further enhancing the production efficiency of the battery core shell 6.

[0038] like Figures 4 to 6 As shown, racetrack-shaped slide rails 36 are provided along both the front and rear sides of the conveyor support 31; the conveyor includes a conveyor base 37 and a conveyor plate 38; the conveyor base 37 is U-shaped with an opening facing downwards, and includes a first side plate 371, a second side plate 372, and a connecting plate 373; the lower part of the first side plate 371 of the conveyor base 37 is fixedly connected to the transmission chain 35, and the upper part of the first side plate 371 is provided with a first pulley 374 that cooperates with the racetrack-shaped slide rails 36; the second side plate 372 of the conveyor base 37... The upper part is provided with a second pulley 375 that cooperates with the racetrack-shaped slide rail 36; the connecting plate 373 is connected between the top of the first side plate 371 and the second side plate 372, and the conveying carrier plate 38 is horizontally set on the connecting plate 373. The front and rear sides of the conveying carrier plate 38 are provided with limiting blocks 381 that cooperate with the battery cell shell 6. Each conveying carrier plate 38 is provided with four L-shaped limiting blocks 381, and the four limiting blocks 381 are respectively set at the four corners of the conveying carrier plate 38, which can limit and support the bottom of the battery cell shell 6. The conveying base 37, with its U-shaped structure, can further improve the connection strength and support stability, ensuring that the battery cell shell 6 can be placed stably on the conveying carrier plate 38 and conveyed stably. At the same time, the first pulley 374 and the second pulley 375 are located on both sides of the racetrack-shaped slide rail 36, which can ensure the smoothness and fluidity of the conveying, as well as the stability and support during the overall sliding process, further ensuring the stability and accuracy of the entire feeding process.

[0039] like Figures 4 to 6As shown, at least one conveying positioning component 39 is also provided on one side of the conveying bracket 31; in this embodiment, there are two, each conveying positioning component 39 including a positioning drive 391, a positioning drive swing arm 392, and a positioning shaft 393; the positioning drive 391 is provided on the outer wall of the conveying bracket 31, and the positioning shaft 393 is rotatably connected to the outer wall of the conveying bracket 31 through two positioning shaft brackets 394; one end of the positioning drive swing arm 392 is rotatably connected to the drive part of the positioning drive 391, and the other end of the positioning drive swing arm 392 is fixed to the positioning shaft 393; three positioning rods 395 are arranged at intervals on the positioning shaft 393, and a positioning plate 376 is provided on the side plate of the conveying base 37 near the positioning rods 395; a positioning notch 377 is provided on the positioning plate 376; the end of each positioning rod 395 is provided with a positioning roller 396 that is positioned and engaged with the positioning notch 377; during positioning, the positioning roller 396 is engaged into the positioning notch 377 by swinging the positioning rod 395 to achieve positioning. The positioning drive component 391, in the form of a cylinder, can drive the positioning drive swing arm 392 to rotate, thereby causing the positioning rod 395 on the positioning shaft 393 to rotate. When moving a distance of one workstation, the positioning roller 396 on the positioning rod 395 is rotated into the positioning recess 377, thus ensuring that each movement of the conveying carrier is precise. This ensures the accuracy of each movement and prevents the battery cell shell 6 from failing to be processed or conveyed due to movement errors, further ensuring the accuracy of movement positioning and thus ensuring the accuracy of the entire processing.

[0040] like Figure 7 As shown, symmetrical alignment and positioning mechanisms 5 are arranged on both the front and rear sides of the core shell conveying mechanism 3 on the frame. Each alignment and positioning mechanism 5 includes an alignment and positioning bracket 51, an alignment and positioning cylinder 52, and an alignment and positioning plate 53. The alignment and positioning bracket 51 is vertically arranged on the frame, the alignment and positioning cylinder 52 is horizontally arranged on top of the alignment and positioning bracket 51, and the alignment and positioning plate 53 is vertically arranged on the telescopic rod of the alignment and positioning cylinder 52. The two alignment and positioning plates 53 clamp each other to align and position the battery core shell 6 to the designated position. Through the alignment and positioning mechanisms 5 on both sides, when the battery core shell 6 is placed on the conveying carrier, the alignment and positioning plates 53 on both the front and rear sides move closer to clamp the battery core shell 6, so that the battery core shell 6 can be accurately placed on the conveying carrier, reducing the processing error caused by displacement during the feeding process, and further ensuring the accuracy of feeding, conveying, and subsequent processing.

[0041] When the entire device is in operation, each of the second telescopic sections 132 in the first feeding mechanism 1 and the second feeding mechanism 2 is in the extended state. The operator places a set of battery cell shells 6 into the rectangular space formed by the limiting frames 12 on the left and right sides. Due to the extension of the second telescopic sections 132, multiple battery cell shells 6 can be stacked between the two limiting frames 12. After the battery cell shells 6 are placed, the first telescopic sections 131 of the first feeding mechanism 1 and the second feeding mechanism 2 change from the retracted state to the extended state, entering the waiting state. There is no need to manually place them one by one onto the conveyor belt, reducing manual labor, and it can ensure that the two bottom battery cell shells 6 are supported separately, which facilitates the subsequent transfer and transportation of the bottom battery cell shells 6.

[0042] During loading, the core shell conveying mechanism 3 drives the conveyor belt drive motor 32 to rotate, thereby conveying one of the conveying carriers to the bottom of the battery core shell 6 under the action of the driving gear 33, driven gear 34, and transmission chain 35. The lifting drive component 15 lifts the support plate 151 in the form of a cylinder and places it against the bottom surface of the lowest battery core shell 6. Then, the second telescopic part 132 retracts, at which point the battery core shell 6 is in a free state. As the support plate 151 descends, the battery core shell 6 slowly falls onto the four limit blocks 381 of the conveying plate 38. The core shell conveying mechanism 3 then moves the conveying carrier containing the battery core shell 6 one station to the left. The battery cell shell 6 is removed from the waiting area. During the leftward movement, the positioning drive 391 on the conveying positioning assembly 39 drives the positioning shaft 393 to rotate in the form of a drive cylinder. This causes the positioning roller 396 on the positioning rod 395 to disengage from the positioning recess 377. As a result, the conveying carrier plate 38 can be synchronously conveyed with the transmission chain 35. When it is conveyed to the next station, the positioning drive 391 on the conveying positioning assembly 39 drives the positioning shaft 393 to rotate, causing the positioning roller 396 to re-engage into the positioning recess 377. This ensures the accurate positioning of the conveying carrier plate 38 and prevents the displacement of the conveying from deviating, which could lead to processing errors.

[0043] As the bottommost battery cell shell 6 descends, the positioning block 133 of the second telescopic part 132 extends again. At this time, the positioning block 133 of the first telescopic part 131 retracts, and all the stacked battery cell shells 6 descend to the flat surface 134 of the positioning block 133 at the second telescopic part 132 for support. When the bottommost battery cell shell 6 (originally the second to last) falls into the positioning block 133 of the second telescopic part 132, the positioning block 133 of the first telescopic part 131 gradually extends again and slides into the second to last battery cell shell 6 (originally the third to last) through the guide surface 135 of the positioning block 133 of the second telescopic part 132, and enters the waiting state again, thus completing the feeding and conveying of one battery cell shell 6.

[0044] After being transported to the next workstation, the alignment and positioning cylinders 52 in the alignment and positioning mechanisms 5 on both the front and rear sides drive the alignment and positioning plate 53 to clamp and position the battery cell shell 6. The alignment and positioning plate 53 clamps the battery cell shell 6, and the alignment and positioning cylinders 52 extend to the designated position to position the battery cell shell 6 to the precise processing position. This prevents displacement deviations during the unloading or translational transport of the battery cell shell 6, which could lead to inaccurate subsequent processing. This further ensures the positioning accuracy of the battery cell shell 6 and the quality of subsequent processing, thereby improving the overall feeding efficiency, processing efficiency, and processing quality.
