Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to an automated cell assembly device. Background Technology

[0002] With the booming development of the new energy vehicle industry, the market's requirements for the driving range of electric vehicles are becoming increasingly stringent. Combining multiple battery cells into large battery modules has become a key technological path to meet the demand for long driving range. During the assembly process of battery modules, in order to prevent the casings of adjacent cells from contacting each other, epoxy boards are usually used to effectively separate adjacent cells. Currently, the installation of epoxy boards between adjacent battery cells mainly relies on two traditional manual methods: first, stacking the battery cells and epoxy boards alternately; second, arranging the battery cells neatly first, and then inserting epoxy boards one by one into the gaps between adjacent battery cells.

[0003] However, manual assembly has many drawbacks. On the one hand, manual operation not only consumes a lot of human resources, but also significantly increases the production cost of enterprises. On the other hand, under long-term, high-intensity repetitive labor, operators are prone to fatigue, which can lead to operational omissions, such as over-assembly or under-assembly of epoxy boards, resulting in a lower product qualification rate and affecting production efficiency and product quality. Summary of the Invention

[0004] In order to reduce the labor consumption in the process of adding epoxy boards between battery cells, and to avoid the situation of over-installation or omission of epoxy boards, thereby improving the product qualification rate, this application provides an automatic battery cell assembly device.

[0005] The automatic battery cell assembly device provided in this application adopts the following technical solution: An automatic battery cell assembly device includes a worktable and a fixed frame. The worktable has a feeding port, and a feeding plate is vertically slidable below the feeding port for placing battery cells. A first driving member is provided on the worktable to intermittently move the feeding plate upwards. A receiving plate is vertically slidable at the end of the worktable, and a second driving member is provided on the worktable to intermittently move the receiving plate downwards. A push plate is slidable on the worktable towards or away from the receiving plate, passing above the feeding port, and a third driving member is provided on the worktable to reciprocate the push plate. The fixed frame is located on the side of the receiving plate away from the feeding port, and a storage box for holding epoxy boards is fixedly mounted on the fixed frame. The storage box has a dispensing port facing upwards towards the receiving plate, and a pushing mechanism is also provided on the storage box for intermittently pushing the epoxy boards out of the storage box from the dispensing port.

[0006] By adopting the above technical solution, before adding epoxy boards between battery cells, several battery cells are first stacked on a loading plate, and several epoxy boards are placed in a storage box. Then, the device is activated, and the first, second, and third driving components and the ejection mechanism operate in sequence: the first driving component first moves the loading plate a certain distance, and the battery cell at the top of the loading plate is ejected from the loading port; then, the third driving component drives a push plate to slide close to the receiving plate, pushing the battery cell at the loading port onto the receiving plate, and then the push plate slides back to its original position; during the push plate's resetting process, the second driving component and the ejection mechanism operate simultaneously; the ejection mechanism on the storage box ejects the epoxy board from the outlet, causing the epoxy board to land above the battery cell on the receiving plate; simultaneously, the second driving component drives the receiving plate to descend a certain distance, ensuring that the epoxy board on the receiving plate is not higher than the upper surface of the worktable in the height direction; then, the first driving component operates again, and this process is repeated, causing the battery cells and epoxy boards to be continuously stacked alternately on the receiving plate. This reduces the manpower required for the epoxy board process, minimizes the possibility of overfilling or underfilling epoxy boards, and improves the product qualification rate.

[0007] Preferably, the ejection mechanism includes a friction roller and a rotary drive assembly. The friction roller rotates inside the storage box and abuts against the epoxy board inside the storage box. The rotary drive assembly 32 is used to drive the friction roller to rotate.

[0008] By adopting the above technical solution, the rotary drive component drives the friction roller to rotate. Under the action of friction, the rotating friction roller pushes the epoxy board in contact with the friction roller to move towards the board outlet until it is pushed out from the board outlet, thus realizing the function of pushing the epoxy board out of the board outlet of the storage box.

[0009] Preferably, a pressure plate is slidably disposed inside the storage box. The pressure plate is located on the side of the storage box away from the friction roller. A thrust spring is disposed between the pressure plate and the inner wall of the storage box, and the thrust spring drives the pressure plate to approach the friction roller.

[0010] By adopting the above technical solution, as epoxy boards are used, the total thickness of all epoxy boards in the storage box is reduced. The thrust spring drives the pressure plate to approach the friction roller, and the pressure plate pushes the epoxy board closer to the friction roller and abuts against the friction roller, thereby ensuring as much as possible that the contact effect between the epoxy board and the friction roller will not decrease as the epoxy board is used and consumed.

[0011] Preferably, the rotary drive assembly includes a rack and a gear. The rack is fixedly connected to the push plate, and the gear is coaxially mounted on the friction roller. The gear can drive the friction roller to rotate, and the rack and gear mesh with each other.

[0012] By adopting the above technical solution, the pusher plate slides down under the drive of the third driving component, and the rack fixedly connected to the pusher plate moves synchronously. The rack meshes with the gear to drive the gear to rotate, thereby driving the friction roller to rotate. When the pusher plate approaches the receiving plate, the friction roller rotates in one direction. However, at this time, the friction roller contacts the epoxy board, and the direction of the thrust applied to the epoxy board is not towards the outlet. Therefore, the epoxy board cannot move. When the pusher plate resets, the rotation of the friction roller pushes the epoxy board out of the outlet. In this way, the epoxy board can be pushed out without an independent power source, reducing costs. In addition, the epoxy board pushing action follows immediately after the battery cell is pushed onto the receiving plate, improving the orderliness of the alternating stacking of epoxy boards and battery cells, and further helping to avoid the situation of overloading or missing epoxy boards.

[0013] Preferably, the rotary drive assembly further includes a rotating wheel, a push pawl, a ratchet, and a first torsion spring. The ratchet is coaxial with and fixedly connected to the friction roller. The gear is coaxial with and rotatably connected to the friction roller. The rotating wheel is fixed to the gear on the side near the ratchet. The push pawl rotates on the side wall of the rotating wheel. The first torsion spring is disposed at the rotatable connection between the push pawl and the rotating wheel. The first torsion spring drives the push pawl to abut against the ratchet teeth of the ratchet.

[0014] By adopting the above technical solution, when the push plate drives the rack to slide back and forth, the gear rotates with the rack and drives the rotating wheel to rotate synchronously; under the action of the first torsion spring, the pawl is pushed to abut against the ratchet teeth of the ratchet wheel; when the push plate is reset, the gear rotates in the forward direction, pushing the pawl to abut against the ratchet teeth of the ratchet wheel, driving the ratchet wheel to rotate in the same direction, thereby driving the friction roller to rotate to push out the epoxy board; when the push plate is close to the receiving plate, the gear rotates in the reverse direction, pushing the pawl to slide along the surface of the ratchet teeth, and the ratchet wheel and the friction roller remain stationary; in this way, the friction roller rotates only in one direction when the push plate is reset, ensuring that the epoxy board is pushed out immediately after the battery cell is pushed into place, and preventing the friction roller from driving the epoxy board to slide away from the outlet as much as possible.

[0015] Preferably, the rotary drive assembly further includes a check pawl and a second torsion spring. The check pawl is rotatably mounted on the storage box, and the second torsion spring is disposed between the check pawl and the storage box. The second torsion spring drives the check pawl to abut against the ratchet teeth of the ratchet wheel.

[0016] By adopting the above technical solution, when the pawl drives the ratchet to rotate and push out the epoxy board, the tip of the check pawl is embedded in the ratchet tooth gap of the ratchet under the elastic force of the second torsion spring, preventing the ratchet from rotating in the opposite direction with the gear. Even if the gear tends to rotate in the opposite direction due to external force (such as pushing the pawl), the check pawl will lock the ratchet and prevent the friction roller from rotating in the opposite direction.

[0017] Preferably, a stop is fixedly provided at the end of the workbench. The stop is located below the receiving plate. Several upwardly extending straightening rods are provided on the side wall of the stop. The side walls of all the straightening rods abut against the side walls of the epoxy board and the battery cell on the receiving plate.

[0018] By adopting the above technical solution, when the receiving plate carries the battery cells and epoxy board stacked, the side wall of the aligning rod abuts against the side of the stack composed of the epoxy board and the battery cells, forming a vertical limiting constraint. As the receiving plate moves down intermittently, the stack gradually falls down, and the aligning rod continuously calibrates the lateral position of the stack to prevent the battery cells or epoxy board from tilting or misaligning during the stacking process, so as to ensure that the edges of each layer of battery cells and epoxy board are aligned, making the final stack neatly stacked, and providing a standardized assembly basis for subsequent packaging, welding and other processes.

[0019] Preferably, the leveling rod is rotatably connected to the abutment, and the abutment is provided with an opening and closing mechanism for driving the leveling rod to rotate.

[0020] By adopting the above technical solution, when the receiving plate moves, the opening and closing mechanism drives the aligning rod to rotate, causing the side wall of the aligning rod to detach from the side of the stack and release the limiting constraint; when the receiving plate is stationary, the aligning rod rotates back to the initial position, and the side wall abuts against the stack again, preventing relative friction between the epoxy board and the battery cell and the side wall of the aligning rod when the epoxy board and the battery cell move down together with the receiving plate; and, during the continuous swinging process of the aligning rod, it helps to align and organize the epoxy board and the battery cell.

[0021] Preferably, the opening and closing mechanism includes an extension rod, a tension rope, a winding wheel, and a motor. The motor is fixed to the bottom of the support frame, the winding wheel is coaxial with and fixedly connected to the drive shaft of the motor, the extension rod is fixed to the bottom of the alignment rod, one end of the tension rope is fixed and wound around the winding wheel, and the other end of the tension rope is fixedly connected to the extension rod.

[0022] By adopting the above technical solution, when the motor drives the winding wheel to rotate in the forward direction, the tension rope is gradually wound around the winding wheel. The tension rope pulls the extension rod, causing the aligning rod to rotate away from the epoxy board and the battery cell, thus realizing the opening action of the aligning rod. When the motor drives the winding wheel to rotate in the reverse direction, the tension rope loosens, thereby simultaneously driving all the aligning rods to move.

[0023] Preferably, the opening and closing mechanism further includes a third torsion spring, which is disposed at the rotational connection between the leveling rod and the abutment. The third torsion spring is used to drive the side wall of the leveling rod to abut against the epoxy board and the side wall of the battery cell on the receiving plate.

[0024] By adopting the above technical solution, when the tension rope is slack, the restoring force of the third torsion spring drives the alignment rod to rotate towards the stack, thereby driving the alignment rod to reset and causing the alignment rod to abut against the side wall of the epoxy board and the battery cell again.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a feeding port, feeding plate, first driving component, receiving plate, second driving component, push plate, third driving component, storage box, board outlet, and ejection mechanism, an automated process of alternating stacking of battery cells and epoxy boards is realized, which minimizes operational errors caused by human fatigue, strictly completes the alternation of battery cells and epoxy boards each time, and effectively reduces the situation of overloading or missing epoxy boards. 2. By setting up a friction roller, pressure plate, thrust spring, rack, gear, rotating wheel, push pawl, ratchet, first torsion spring, check pawl, and second torsion spring, the meshing transmission of the rack and gear converts the sliding motion of the push plate into the rotational power of the friction roller, eliminating the need for an additional power source and reducing costs. The cooperation between the gear and ratchet ensures that the friction roller rotates unidirectionally to push out the epoxy plate only when the push plate is reset, preventing misoperation. 3. By setting up a support frame, a aligning rod, an opening and closing mechanism, an extension rod, a tension rope, a winding wheel, a motor, and a third torsion spring, when the receiving plate moves, the aligning rod moves away from the side of the battery cell and the epoxy board and does not contact them. When the receiving plate is stationary, the aligning rod re-abuts against the battery cell and the epoxy board, preventing relative friction between the epoxy board and the side wall of the aligning rod when the receiving plate moves down with it. Furthermore, the continuous swinging of the aligning rod helps to align and organize the epoxy board and the battery cell. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses an automated battery cell assembly device. (Refer to...) Figure 1 It includes a worktable 1 and a fixing frame 2. The worktable 1 is composed of a horizontal top plate and two side plates for supporting the top plate. The side plates are located at both ends of the top plate and extend downward from the bottom of the top plate. The fixing frame 2 is fixed to the end of the worktable 1 by two connecting rods.

[0034] Reference Figure 1 The top plate of the workbench 1 has a vertically extending feed port 11 with rounded corners at the top edge. A feed plate 121 slides vertically below the feed port 11, and is used to hold the battery cells 5. A first driving component 12 is provided on the workbench 1 to intermittently move the feed plate 121 upwards. Specifically, a mounting bracket is fixedly installed below the top plate of the workbench 1; the first driving component 12 is an electric push rod, fixed to the mounting bracket, with its output end facing upwards and fixedly connected to the feed plate 121.

[0035] Reference Figure 1 A receiving plate 131 is vertically slidably mounted at the end of the workbench 1. A second driving member 13 is provided on the workbench 1 to drive the receiving plate 131 to move intermittently downwards. The receiving plate 131 is used to support the stack of battery cells 5 and epoxy boards 6, which are alternately stacked. Specifically, a support frame 15 is fixedly mounted on the side plate at one end of the workbench 1. The second driving member 13 is an electric push rod, which is fixed on the support frame 15. The output end of the second driving member 13 faces upwards and is fixedly connected to the receiving plate 131.

[0036] Reference Figure 1A push plate 141 is slidably mounted on the worktable 1 along the direction of approaching or moving away from the receiving plate 131. The push plate 141 can pass above the loading port 11. A third driving member 14 is provided on the worktable 1 to drive the push plate 141 to slide back and forth. Specifically, the third driving member 14 is an electric push rod, which is fixedly connected to the upper surface of the top plate of the worktable 1. The third driving member 14 is horizontally mounted, and its output end faces the receiving plate 131 and is fixedly connected to the push plate 141. The first driving member 12, the second driving member 13, and the third driving member 14 are all electrically connected to the processor.

[0037] Reference Figures 1 to 5 The fixing frame 2 is located on the side of the receiving plate 131 away from the loading port 11. A storage box 21 for holding epoxy boards 6 is fixedly mounted on the fixing frame 2. The storage box 21 has a discharge port 22 facing upwards from the receiving plate 131. The storage box 21 also has a pushing mechanism 3, which intermittently pushes the epoxy boards 6 out of the storage box 21 through the discharge port 22. Specifically, the pushing mechanism 3 includes a friction roller 31 and a rotary drive assembly 32. The friction roller 31 rotates inside the storage box 21, abutting against the epoxy boards 6 inside the storage box 21. The rotary drive assembly 32 drives the friction roller 31 to rotate. In this embodiment, two friction rollers 31 are rotatably arranged on the bottom side of the storage box 21. One friction roller 31 is located in the middle of the bottom side of the storage box 21, and the other friction roller 31 is located at the discharge port 22. The discharge port 22 only allows a single epoxy board 6 to pass through at a time.

[0038] When an epoxy board 6 needs to be added between battery cells 5, several battery cells 5 are first stacked on the loading plate 121, and several epoxy boards 6 are placed in the storage box 21. Then, the device is activated, and the first drive unit 12, the second drive unit 13, the third drive unit 14, and the ejection mechanism 3 operate in sequence. The first drive unit 12 first causes the loading plate 121 to move upward intermittently once, pushing the topmost battery cell 5 on the loading plate 121 out of the loading port 11. Next, the third drive unit 14 drives the push plate 141 to slide close to the receiving plate 131, pushing the battery cell 5 at the loading port 11 onto the receiving plate 131. Then, the push plate 141 slides back to its original position. During the resetting process of the push plate 141, the second drive unit 13 and the friction roller 31 operate simultaneously. The rotation drive assembly 32 drives the friction roller 31 to rotate, pushing the epoxy board 6 out of the outlet 22, so that the epoxy board 6 covers the battery cell 5 on the receiving plate 131. Simultaneously, the second drive unit 13 drives the receiving plate 131 to descend, so that the epoxy board 6 lands on the receiving plate 131. After landing, the epoxy board 6 is not higher than the upper surface of the workbench 1, making room for the next battery cell 5 to be stacked. Then, the first drive unit 12 operates again, and so on, so that the battery cell 5 and the epoxy board 6 are continuously stacked alternately on the receiving plate 131.

[0039] To ensure the contact pressure between the friction roller 31 and the epoxy plate 6, refer to Figure 5 A pressure plate 23 is slidably disposed inside the storage box 21. The pressure plate 23 is located on the side of the storage box 21 away from the friction roller 31. A thrust spring 24 is disposed between the pressure plate 23 and the inner wall of the storage box 21, and the thrust spring 24 drives the pressure plate 23 to approach the friction roller 31. In addition, a layer of rubber is wrapped around the peripheral wall of the friction roller 31 to increase the friction.

[0040] To achieve orderly rotation of the friction roller 31, refer to Figures 2 to 4 The rotary drive assembly 32 includes a rack 321, a gear 322, a rotating wheel 323, a push pawl 324, a ratchet 326, a first torsion spring 325, a check pawl 327, and a second torsion spring 328. The rack 321 is fixedly connected to the push plate 141, and the gear 322 is coaxially mounted on the friction roller 31. The rack 321 and the gear 322 mesh with each other. Specifically, each of the two friction rollers 31 is coaxially mounted with a gear 322, and the two gears 322 mesh with the same rack 321. The gear 322 on the friction roller 31 located in the middle of the bottom side of the storage box 21 can disengage from the rack 321.

[0041] Reference Figure 2 and Figure 4 Gear 322 drives friction roller 31 to rotate. Specifically, rack 321 is located above gear 322, and gear 322 is coaxial with and rotatably connected to friction roller 31. Ratchet 326 is coaxial with and fixedly connected to friction roller 31. Rotating wheel 323 is fixed to gear 322 on the side near ratchet 326, pushing pawl 324 to rotate on the side wall of rotating wheel 323. First torsion spring 325 is disposed at the rotatable connection between pushing pawl 324 and rotating wheel 323, and first torsion spring 325 drives pushing pawl 324 to abut against the ratchet teeth of ratchet 326. Check pawl 327 is rotatably disposed on storage box 21, and second torsion spring 328 is disposed between check pawl 327 and storage box 21, and second torsion spring 328 drives check pawl 327 to abut against the ratchet teeth of ratchet 326.

[0042] Reference Figure 2 and Figure 4The rack 321 moves synchronously with the push plate 141, meshing with the gear 322 to drive the gear 322 to rotate, thereby driving the rotating wheel 323 to rotate. When the push plate 141 approaches the receiving plate 131, the rotating wheel 323 rotates, and the check pawl 327 locks the ratchet 326, preventing the ratchet 326 from rotating in the opposite direction, pushing the pawl 324 to slip on the ratchet 326, keeping the ratchet 326 stationary with the friction roller 31. When the push plate 141 resets, the gear 322 rotates in the other direction, pushing the pawl 324 against the ratchet teeth of the ratchet 326, causing the ratchet 326 to rotate in the same direction, thereby driving the friction roller 31 to rotate. Under the action of friction, the rotating friction roller 31 pushes the epoxy plate 6 in contact with the friction roller 31 towards the outlet 22 until it is pushed out from the outlet 22.

[0043] To ensure the neatness of battery cell 5 and epoxy board 6 during the stacking process, refer to Figure 1 and Figure 3 The support frame 15 has several upwardly extending alignment rods 151 on its side walls. There are three alignment rods 151, located on the three side walls of the support frame 15 that do not contact the worktable 1. All alignment rods 151, along with the side plate at one end of the worktable 1, surround the stacked body on the receiving plate 131 composed of epoxy board 6 and battery cell 5. The side walls of all alignment rods 151 abut against the side walls of the epoxy board 6 and battery cell 5 on the receiving plate 131. The alignment rods 151 are rotatably connected to the support frame 15, which has an opening and closing mechanism 4 for driving the alignment rods 151 to rotate. Specifically, the opening and closing mechanism 4 includes an extension rod 41, a tension rope 42, a winding wheel 43, a motor, and a third torsion spring 44. The motor is fixed to the bottom of the support frame 15 and is electrically connected to the processor. The winding wheel 43 is coaxial with and fixedly connected to the drive shaft of the motor. The extension rod 41 is fixed to the bottom of the leveling rod 151. One end of the tension rope 42 is fixed and wound around the winding wheel 43, and the other end of the tension rope 42 is fixedly connected to the extension rod 41. The third torsion spring 44 is set at the rotatable connection between the leveling rod 151 and the support frame 15. The third torsion spring 44 is used to drive the side wall of the leveling rod 151 to abut against the side wall of the epoxy board 6 and the battery cell 5 on the receiving plate 131.

[0044] Reference Figure 1 and Figure 3When the receiving plate 131 moves, the motor drives the winding wheel 43 to rotate, and the tension rope 42 is further wound and tightened by the winding wheel 43. The tension rope 42 pulls the extension rod 41 and drives the leveling rod 151 to rotate away from the stack, so that the side wall of the leveling rod 151 is separated from the side of the stack. When the receiving plate 131 is stationary, the motor drives the winding wheel 43 to rotate in the opposite direction, the tension rope 42 is relaxed, and the restoring force of the third torsion spring 44 drives the leveling rod 151 to reset, so that the leveling rod 151 abuts against the side wall of the stack again, so as to limit the epoxy board 6 and the battery cell 5 in the stack. During the continuous swinging process of the leveling rod 151, the leveling rod 151 pushes the epoxy board 6 and the battery cell 5 to align.

[0045] The implementation principle of an automatic battery cell assembly device according to an embodiment of this application is as follows: After the device is started, the first driving member 12 drives the feeding plate 121 to move upward intermittently once, and the battery cell 5 at the top of the feeding plate 121 is pushed out of the feeding port 11. Then, the third driving member 14 drives the push plate 141 to slide close to the receiving plate 131, pushing the battery cell 5 at the feeding port 11 onto the receiving plate 131. The rack 321 meshes with the gear 322 to drive the gear 322 to rotate, but the ratchet 326 cannot rotate due to the obstruction of the check pawl 327. Subsequently, the push plate 141 slides in the opposite direction to reset. During the reset process of the push plate 141, the rack 321 meshes with the gear 322 to rotate in another direction, pushing the pawl 324 to abut against the ratchet 326 and driving the ratchet 326 to rotate. The ratchet 326 drives the friction roller 31 to rotate, pushing the epoxy plate 6 out of the outlet 22, so that the epoxy plate 6 covers the battery cell 5 on the receiving plate 131. Simultaneously, the second drive unit 13 lowers the receiving plate 131, causing the epoxy board 6 to land on it. The epoxy board 6 is then positioned no higher than the upper surface of the workbench 1, creating space for the next battery cell 5 to be stacked. Afterwards, the first drive unit 12 operates again, repeating the process of feeding the battery cell 5, pushing the battery cell 5, pushing out the epoxy board 6, and lowering the receiving plate 131, causing the battery cell 5 and epoxy board 6 to be continuously stacked alternately on the receiving plate 131. This reduces the manpower required for adding epoxy boards 6 between battery cells 5, minimizes the possibility of overloading or missing epoxy boards 6, and improves the product qualification rate.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
