Description

Technical Field

[0001] The present invention relates to production equipment for lithium battery cells or lithium battery modules, and more specifically to a device for pasting and rolling flat adhesive tapes on battery cells. Background Art

[0002] When some lithium battery production enterprises produce lithium battery cells or lithium battery modules, they will paste insulating tapes on the sides of the battery cells according to the process requirements of customers to protect the battery cells. During the process of pasting the insulating tapes, the excess tapes at the upper ends need to be flattened onto the upper surfaces of the battery cells. Usually, the steps of pasting adhesive tapes on the battery cells and flattening the tapes are completed manually.

[0003] Manual pasting of adhesive tapes on battery cells has low production efficiency and increases product costs. In addition, manual pasting of adhesive tapes cannot guarantee the quality of the pasted tapes and cannot meet the requirements of customers. Summary of the Invention

[0004] Aiming at the problem of low efficiency of manual pasting of adhesive tapes on existing battery cells, the present invention provides a device for pasting and rolling flat adhesive tapes on battery cells that is efficient and can guarantee the quality of tape pasting.

[0005] The technical solution of the device for pasting and rolling flat adhesive tapes on battery cells in the present invention is as follows: A device for pasting and rolling flat adhesive tapes on battery cells is used to paste tapes on the sides of battery cells and paste and flatten the unpasted parts of the tapes attached to the two sides of the battery cells onto the upper surfaces of the battery cells. The device for pasting and rolling flat adhesive tapes on battery cells includes a transfer platform, a pasting part, and a rolling flat part; wherein: The transfer platform is configured to carry the battery cells to be pasted with adhesive tapes when at the pasting part and carry the battery cells with tapes to be flattened when at the rolling flat part; The pasting part includes a tape feeding assembly, a traction assembly, a cutting assembly, and a pasting assembly; The tape feeding assembly is used to store tapes; The traction assembly is configured to pull out a fixed length of tape from the tape feeding assembly; The cutting assembly is configured to cut the tape of a fixed length; The pasting assembly sucks the fixed length of tape pulled out by the traction assembly and pastes the tape on the side of the battery cell; The rolling flat part includes a rolling flat translation mechanism and a rolling flat mechanism; The rolling flat translation mechanism is configured to drive the rolling flat mechanism to reach or move away from the flattening position of the battery cell on the transfer platform; The rolling flat mechanism is installed on the rolling flat translation mechanism and is configured to paste and flatten the unpasted parts of the tapes attached to the two sides of the battery cell on the transfer platform onto the upper surface of the battery cell.

[0006] Through the combination of the pasting part and the rolling flat part, the operations of pasting adhesive tapes on the sides of battery cells and flattening the tapes on the surfaces of the battery cells can be mechanized. Compared with manual pasting and sorting, not only the production efficiency is greatly improved, but also the quality of tape pasting is ensured.

[0007] Further, the glue - sticking part further includes a jacking mechanism, which is configured to jack up the battery cells to be glued on the transfer platform to the glue - sticking position of the glue - sticking part; the jacking mechanism includes a first jacking mechanism, a second jacking mechanism and a top plate, and the top plate is located above the first jacking mechanism; the second jacking mechanism is installed below the first jacking mechanism, and the first jacking mechanism is installed on the moving part of the second jacking mechanism; or, the second jacking mechanism is installed between the first jacking mechanism and the top plate, the second jacking mechanism is installed on the moving part of the first jacking mechanism, and the top plate is installed on the moving part of the second jacking mechanism; the battery cells on the transfer platform rise to the glue - sticking position under the jacking of the first jacking mechanism and / or the second jacking mechanism.

[0008] The battery cells are jacked up to the glue - sticking position by the jacking mechanism to make necessary preparations for gluing the battery cells; two jacking mechanisms are adopted. One jacks up quickly to improve efficiency, and the other jacks up slowly to avoid the top plate impacting the battery cells and ensure the accuracy of the action.

[0009] Further, the tape feeding assembly includes a tape mounting disk, a transition pulley and a clamping mechanism. The tape is mounted on the tape mounting disk, passes through the transition pulley and is clamped in the clamping mechanism. The clamping mechanism is configured to open when feeding the tape so that the tape can be moved, and to clamp when not feeding the tape so that the tape is fixed.

[0010] The tape feeding assembly clamps the head of the tape through the clamping mechanism, facilitating the subsequent traction action of the traction assembly.

[0011] Further, the traction assembly includes a motor, a synchronous belt and a pressing head assembly. The pressing head assembly is fixed on the synchronous belt, and the motor drives the synchronous belt to move, thereby driving the pressing head assembly to move back and forth; the pressing head assembly includes a pressing head mounting plate, a pressing block, a fixing plate and a pressing block pushing mechanism. The fixing plate is installed on the pressing head mounting plate, the pressing block is opposite to the fixing plate and is installed on the moving part of the pressing block pushing mechanism, and the pressing block pushing mechanism is fixedly connected to the pressing head mounting plate; the pressing block pushing mechanism pushes the pressing block towards the fixing plate until the pressing block fits with the fixing plate, thereby clamping the tape.

[0012] The traction assembly uses the synchronous belt to cooperate with the pressing head assembly. The pressing head clamps the tape, and the synchronous belt drives the tape to move, making preparations for subsequent fixed - length cutting; the pressing head assembly combines the pressing block and the fixing plate to make the clamping of the tape firm and not fall off.

[0013] Further, the cutting assembly includes a mounting seat, a cutting knife, a mounting seat slide rail and a cutting knife pushing mechanism. The cutting knife is fixedly installed on the mounting seat, the mounting seat is slidably matched with the mounting seat slide rail, and the cutting knife pushing mechanism is connected to the mounting seat; the cutting knife pushing mechanism drives the mounting seat to slide on the mounting seat slide rail.

[0014] The cutting knife of the cutting assembly directly cuts the tape under the push of the pushing mechanism, with a simple structure and reliable action.

[0015] Further, the tape sticking assembly includes a suction plate, a telescopic mechanism and a tape sticking lifting mechanism. The suction plate is installed on the movable part of the telescopic mechanism, and the telescopic mechanism is installed on the tape sticking lifting mechanism. When the tape sticking lifting mechanism moves to the upper position, the suction plate sucks the tape. When the tape sticking lifting mechanism moves to the lower position, the telescopic mechanism drives the suction plate to extend and stick the tape on the side of the battery cell.

[0016] The tape sticking assembly realizes sticking the tape on the side of the battery cell through the cooperation of the telescopic mechanism and the lifting mechanism, which can replace manual labor and improve efficiency.

[0017] Further, the rolling and leveling translation mechanism includes a translation driving mechanism, a translation mounting plate and translation guide rails. The translation driving mechanism is installed on the translation mounting plate, and the rolling and leveling mechanism is installed on the movable part of the translation driving mechanism. The rolling and leveling translation mechanism drives the rolling and leveling mechanism to translate.

[0018] The rolling and leveling translation mechanism drives the rolling and leveling mechanism to move to the leveling position to complete the leveling action of the battery cell tape. The structure is simple. The rolling and leveling translation mechanism is guided by the translation guide rails, so that the rolling and leveling mechanism can be lifted and lowered smoothly, ensuring the accuracy of the action.

[0019] Further, the rolling and leveling mechanism includes a rolling and leveling mounting plate, rollers, roller mounting brackets and roller driving mechanisms. The rollers are rotatably installed on the roller mounting brackets, the roller mounting brackets are hinged to the rolling and leveling mounting plate, the roller driving mechanisms are fixedly connected to the rolling and leveling mounting plate, and the movable parts of the roller driving mechanisms are fixedly connected to the roller mounting brackets. There are two sets of rolling and leveling mechanisms and rolling and leveling translation mechanisms respectively. The two sets of rollers are installed side by side on the translation guide rails. The two rollers approach or move away from each other respectively driven by their respective corresponding translation driving mechanisms, and the two rollers descend or ascend respectively driven by their respective corresponding roller driving mechanisms.

[0020] The rolling and leveling mechanism uses rotatable rollers, which have low running resistance and will not interfere with the battery cell. The rolling and leveling mechanism uses two rollers, which can shorten the leveling time and improve work efficiency.

[0021] Further, the transfer platform includes a platform bottom plate, a battery cell bottom plate, clamping plates, clamping plate slide rails, clamping plate driving mechanisms, regularizing plates, and regularizing plate driving mechanisms. The battery cell bottom plate is installed in the middle of the platform bottom plate and is configured to carry the battery cells. Two clamping plates are relatively distributed on both sides of the battery cell bottom plate and are slidably engaged with the clamping plate slide rails. The clamping plate slide rails are fixedly installed on the platform bottom plate. The two clamping plates are respectively connected to the movable components of the two clamping plate driving mechanisms. Two regularizing plates are relatively distributed on the other two sides of the battery cell bottom plate and are respectively fixedly connected to the movable components of the two regularizing plate driving mechanisms. The regularizing plate driving mechanisms and the clamping plate driving mechanisms are respectively fixedly installed on the platform bottom plate. The clamping plate driving mechanisms drive the clamping plates to slide along the clamping plate slide rails so as to approach or move away from the battery cell bottom plate, thereby loosening or clamping the battery cells to which the adhesive tape is to be attached or the tape is to be flattened. The regularizing plate driving mechanisms drive the regularizing plates to approach or move away from the battery cell bottom plate, thereby regularizing or loosening the battery cells to which the adhesive tape is to be attached or the tape is to be flattened. After the battery cells are clamped, the upper surfaces of the battery cells are higher than the upper surfaces of the clamping plates.

[0022] The transfer platform uses the cooperation of the clamping plates and the regularizing plates to regularize the battery cells while clamping them, making the positioning of the battery cells accurate and facilitating subsequent operations.

[0023] Further, the battery cell adhesive tape pasting and flattening device further includes a rotating part, a feeding part, a rotating handling part, and a discharging part. The rotating part includes at least two transfer platforms and a rotating mechanism. The rotating mechanism drives each transfer platform to rotate to the working station. The feeding part is configured to cache a plurality of battery cells to which the adhesive tape is to be attached. The discharging part is configured to cache the battery cells after the adhesive tape is pasted and flattened. The rotating handling part is configured to transport the battery cells to which the adhesive tape is to be attached to the transfer platforms of the rotating part, and to transport the battery cells after the adhesive tape is pasted and flattened from the transfer platforms of the rotating part to the discharging part.

[0024] By using the rotating part to transfer workpieces between various stations, the working rhythm can be accelerated and the transfer efficiency can be improved. By configuring the feeding part, the rotating handling part, and the discharging part, the feeding and discharging of the battery cells can be automated, improving the entire working process.

[0059] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0060] The present invention is a cell gluing and rolling and flattening device, which is used to protect the cell and automatically complete gluing on the edge of the cell and rolling and flattening the tape.

[0061] Figure 1 、 Figure 2 Shown is an optional embodiment of the cell gluing and rolling and flattening device 1. Figure 1 It is a perspective view of the device. Figure 2 It is a top view of the device. Specifically, the cell gluing and rolling and flattening device 1 is used to paste a tape on the side surface of the cell 100, and paste and flatten the unpasted part of the tape attached to both side surfaces of the cell 100 onto the upper surface of the cell 100.

[0062] The cell gluing and rolling and flattening device 1 at least includes a transfer platform 30, a gluing part 60 and a rolling and flattening part 70. The transfer platform 30 is configured to carry the cell 100 to be glued at the gluing part 60, and carry the cell 100 with the tape to be flattened at the rolling and flattening part 70; the gluing part 60 is configured to paste the tape onto the side surface of the cell 100; the rolling and flattening part 70 is configured to paste the unpasted part of the tape attached to both side surfaces of the cell 100 on the transfer platform 30 onto the upper surface of the cell 100 and flatten it.

[0063] Through the combination of the transfer platform 30, the gluing part 60 and the flattening part 70, the gluing on the side of the battery cell 100 and the flattening of the tape on the surface of the battery cell 100 can be mechanized. Compared with manual gluing and sorting, not only the production efficiency is greatly improved, but also the pasting quality of the tape is guaranteed.

[0064] Optionally, the battery cell gluing and flattening device 1 further includes a loading part 10, a rotating handling part 20, a rotating part 40 and an unloading part 80. The loading part 10 is configured to cache a plurality of battery cells 100 to be glued; the unloading part 80 is configured to cache the battery cells 100 after gluing and flattening; the rotating handling part 20 is configured to transport the battery cells 100 to be glued to the transfer platform 30 of the rotating part 40, and transport the battery cells 100 after gluing and flattening from the transfer platform 30 of the rotating part 40 to the unloading part 80.

[0065] By rotating the part 40 to transfer the workpiece between each station, the working rhythm can be accelerated and the transfer efficiency can be improved; by configuring the loading part 10, the rotating handling part 20 and the unloading part 80, the loading and unloading of the battery cells 100 can be automated, and the entire working process can be improved.

[0066] The following will make a detailed description of each component of the battery cell gluing and flattening device 1.

[0067] As Figure 1 、 Figure 2 shown, the loading part 10 is used to input the battery cells 100 to be glued into the battery cell gluing and flattening device 1, and the unloading part 80 is used to output the battery cells 100 after gluing and flattening from the battery cell gluing and flattening device 1. In the present invention, the loading part 10 and the unloading part 80 adopt the same structure, and its function is to sequentially transport the battery cells 100 one by one. Of course, different structures can also be adopted. The structure of the loading part 10 will be used as an example for description below.

[0068] Figure 3 、 Figure 4 shown is an optional embodiment of the loading part 10, Figure 3 is a perspective view of this component from one angle, Figure 2 is a perspective view of this component from another angle.

[0069] The loading part 10 includes a cache platform 11, a cache handling mechanism 12 and a cache translation mechanism 13. A plurality of intervals are arranged on the cache platform 11 for caching the battery cells 100 and placing each battery cell separately. The cache translation mechanism 13 is installed at the lower part of the cache platform 11, and the cache handling mechanism 12 is installed on the cache translation mechanism 13. The cache handling mechanism 12 rises to lift the battery cells 100 on the cache platform 11. After the cache translation mechanism 13 drives the cache handling mechanism 12 to move horizontally in place, the cache handling mechanism 12 descends to place the battery cells 100 on the cache platform 11.

[0070] The loading section 10 combines a handling mechanism and a translation mechanism to move the battery cells 100 one by one to the loading station, facilitating the operations of subsequent processes.

[0071] Optionally, the buffer handling mechanism 12 includes a top plate and a lifting cylinder; the buffer translation mechanism 13 includes a driving motor and a slide rail, and the driving motor drives the handling mechanism to move back and forth along the slide rail. When the loading section 10 is operating, the lifting cylinder rises, the top plate lifts the battery cell, the driving motor drives the buffer handling mechanism 12 to move forward, and after reaching the position, the lifting cylinder descends to place the battery cell on the previous buffer position.

[0072] Refer to Figure 1 and Figure 2 Optionally, the loading section 10 and the discharging section 80 are spaced apart in a straight line, and the rotary handling section 20 is located within the interval between them. The function of the rotary handling section 20 is to transport the battery cells 100 conveyed by the loading section 10 to the rotary section 40, and to transport the battery cells 100 that have been completed with glue pasting and leveling on the rotary section 40 to the discharging section 80.

[0073] Figure 5 and Figure 6 As shown in Figure 5 is a perspective view of this component, Figure 6 and

[0074] This rotary handling section 20 includes a suction mechanism 21 and a rotary mechanism 22. There are multiple suction mechanisms 21, which are installed on the rotary mechanism 22. The operation of the rotary mechanism 22 drives the suction mechanism 21 to rotate, so that the position of the suction mechanism 21 rotates from the loading section 10 to the rotary section 40, or from the rotary section 40 to the discharging section 80.

[0075] In this embodiment, four suction mechanisms 21 are provided, which can simultaneously load the glue pasting and leveling devices 1 for the battery cells on both sides of the rotary handling section 20. Figure 1 and Figure 2 only show the glue pasting and leveling device 1 for the battery cells on one side (right side) of the rotary handling section 20, and two suction mechanisms 21 in Figure 5 and Figure 6 are used.

[0076] Optionally, the suction mechanism 21 includes a suction lifting cylinder 211 and a suction cup assembly 212. The suction cup assembly 212 is installed on the suction lifting cylinder 211, and the suction lifting cylinder 211 is installed on the rotary mechanism 22. The suction lifting cylinder 211 drives the suction cup assembly 212 to move up and down, and the suction cup assembly 212 is used to suck or release the battery cell 100.

[0077] As shown in Figure 1 and Figure 2As shown, the rotating part 40 is located in the subsequent process of the rotary handling part 20. The function of the rotating part 40 is to transfer the battery cells 100 between various workstations. An optional embodiment of the rotating part 40 includes at least two transfer platforms 30 and a rotating mechanism 41. The rotating mechanism 41 drives each transfer platform 30 to rotate to the working station. Figure 1 、 Figure 2 As shown in Figure 2 , there are three transfer platforms 30, which are distributed in the circumferential direction of the rotating mechanism 41. The three transfer platforms 30 respectively correspond to the three workstations of the rotating part 40, namely the loading / unloading position, the gluing position, and the flattening position. The rotating mechanism 41 can adopt any form in the prior art, generally in the form of a motor driving a reduction mechanism. The rotating mechanism 41 rotates, driving the three transfer platforms 30 to rotate. Each transfer platform 30 sequentially moves from the loading / unloading position, to the gluing position, then to the flattening position, and then back to the loading / unloading position to complete a working cycle.

[0078] The transfer platform 30 is configured to carry the battery cell 100 to be glued or the battery cell 100 after gluing and flattening at the loading / unloading position, carry the battery cell 100 to be glued at the gluing position (i.e., at the gluing part 60), and carry the battery cell 100 to be flattened with the tape at the flattening part 70.

[0079] Figure 7 、 Figure 8 As shown in Figure 8 is an optional embodiment of the transfer platform 30, Figure 7 is the perspective view of this component, Figure 8 is the top view of this component.

[0080] The transfer platform 30 includes a platform bottom plate 31, clamping plates 32, a battery cell bottom plate 33, clamping plate slide rails 34, a clamping plate driving mechanism 35, a regularizing plate 36, and a regularizing plate driving mechanism 37.

[0081] The platform bottom plate 31 fixedly connects the transfer platform 30 to the rotating part 40.

[0082] The battery cell bottom plate 33 is installed in the middle of the platform bottom plate 31 and is configured to carry the battery cell. The battery cell bottom plate 33 is located below the battery cell and rises together with the battery cell during gluing. A reserved hole is provided in the middle of the battery cell bottom plate 33 to allow the suction cup of the lifting mechanism to pass through. The suction cup sucks the battery cell to prevent the battery cell from shifting.

[0083] Two clamping plates 32 are oppositely distributed on both sides of the battery cell bottom plate 33 and are slidably fitted on the clamping plate slide rails 34. The clamping plate slide rails 34 are fixedly installed on the platform bottom plate 31. The two clamping plates 32 are respectively connected to the movable parts of the two clamping plate driving mechanisms 35. The clamping plate driving mechanisms 35 are fixedly installed on the platform bottom plate 35. The clamping plate driving mechanisms 35 usually adopt cylinders.

[0084] Two regularizing plates 36 are oppositely distributed on the other two sides of the battery cell bottom plate 33 and are respectively fixedly connected to the movable parts of two regularizing plate driving mechanisms 37. The regularizing plate driving mechanisms 37 are fixedly installed on the platform bottom plate 31. The regularizing plate driving mechanisms 37 also generally adopt air cylinders.

[0085] The clamping plate driving mechanism 35 drives the clamping plate 32 to slide along the clamping plate slide rail 34 so as to approach or move away from the battery cell bottom plate 33, thereby loosening or clamping the battery cell 100 to be glued or the battery cell 100 with the tape to be flattened; while clamping the battery cell 100, the battery cell is regularized in the front-back direction (i.e., the short side position of the battery cell). The regularizing plate driving mechanism 37 drives the regularizing plate 36 to approach or move away from the battery cell bottom plate 33, thereby regularizing or loosening the battery cell to be glued or the battery cell with the tape to be flattened; the regularizing plate 36 regularizes the battery cell in the left-right direction (i.e., the long side position of the battery cell). After the battery cell is clamped, the upper surface of the battery cell is higher than the upper surfaces of the clamping plate 32 and the battery cell bottom plate 33.

[0086] The transfer platform 30 uses the clamping plate 32 and the regularizing plate 36 to cooperate to clamp the battery cell 100, and regularizes the battery cell while clamping it, so that the positioning of the battery cell is accurate and subsequent operations are facilitated.

[0087] As Figure 1 、 Figure 2 shown, the battery cell 100 on the transfer platform 30 is driven by the rotating part 40 to rotate from the loading and unloading position to the gluing position, that is, the gluing part 60. The gluing part 60 is used to stick the tape to the side of the battery cell 100.

[0088] Figure 9 、 Figure 10 shown is an optional embodiment of the gluing part 60, Figure 9 is the three-dimensional view of this component, Figure 10 is the front view of this component.

[0089] As Figure 11 、 Figure 12 shown, the gluing part 60 mainly includes a tape loading component 61, a traction component 62, a cutting component 63 and a gluing component 64. The tape loading component 61 is used to store the tape; the traction component 62 is configured to pull out a fixed-length tape from the tape loading component 61; the cutting component 63 is configured to cut the fixed-length tape; the gluing component 64 sucks the fixed-length tape pulled out by the traction component 62 and pastes the tape to the side of the battery cell 100.

[0090] The gluing part 60 can realize the integration of tape storage, traction, cutting and gluing, with a compact structure and small occupied space.

[0091] Figure 13 、 Figure 14 shown is an optional embodiment of the tape loading component 61,Figure 13 This is a perspective view of the component. Figure 14 This is a top view of the component.

[0092] The tape loading assembly 61 includes a tape mounting disc 611, a transition wheel 612, and a clamping mechanism 613. The tape is mounted on the tape mounting disc 611, passes through the transition wheel 612, and is then clamped in the clamping mechanism 613. The clamping mechanism 613 is configured to open when loading the tape so that the tape can be moved, and to clamp when not loading the tape to fix the tape. The clamping mechanism 613 includes a cylinder and a clamping plate, and the cylinder controls the opening and clamping of the clamping plate to release or clamp the tape.

[0093] The tape loading assembly 61 clamps the head of the tape through the clamping mechanism 613, facilitating the subsequent pulling action of the pulling assembly 62. When the tape loading assembly 61 is in use, manually thread the tape along a fixed trajectory, that is, pull the head of the tape out of the tape mounting disc 611, bypass the transition wheel 612, and then clamp the head of the tape in the clamping mechanism 613.

[0094] In this embodiment, the tape loading assembly 61 includes two sets, which are symmetrically arranged and can be used for loading two rolls of tape at the same time, corresponding to the two side edges of the battery cell 100 that need to be pasted with tape respectively.

[0095] Figures 15 to 18 Shown is an alternative embodiment of the pulling assembly 62. Figure 15 This is a perspective view of the component. Figure 16 This is the front view of the component. Figure 17 This is the perspective view of the component after removing the synchronous belt. Figure 18 This is the top view of the component after removing the synchronous belt. The pulling assembly 62 is used to pull the tape from the clamping mechanism 613 of the tape loading assembly 61.

[0096] The pulling assembly 62 includes a motor 621, a synchronous belt 622, and a pressing head assembly 623. The pressing head assembly 623 is fixed on the synchronous belt 622 through a fixing block. The motor 621 drives the synchronous belt 622 to move, and then drives the pressing head assembly 623 to move back and forth.

[0097] Figure 19 、 Figure 20 Shown is an alternative embodiment of the pressing head assembly 623. Figure 19 This is the perspective view of the component assembled with the cutting assembly 63. Figure 20 This is the perspective view of the component.

[0098] The indenter assembly 623 includes an indenter mounting plate 6231, a pressing block 6232, a fixing plate 6233, and an indenter pushing mechanism 6234. The fixing plate 6233 is mounted on the indenter mounting plate 6231. The pressing block 6232 is opposite to the fixing plate 6233 and is mounted on the movable part of the indenter pushing mechanism 6234. The indenter pushing mechanism 6234 is fixedly connected to the indenter mounting plate 6231. The indenter pushing mechanism 6234 pushes the pressing block 6232 towards the fixing plate 6233 until the pressing block 6232 fits against the fixing plate 6233, thereby clamping the tape. The indenter pushing mechanism 6234 usually uses a cylinder.

[0099] The traction assembly 62 uses a synchronous belt 622 to cooperate with the indenter assembly 623. The indenter clamps the tape, and the synchronous belt 622 drives the tape to move, preparing for subsequent fixed-length cutting. The indenter assembly 623 combines the pressing block 6232 and the fixing plate 6233 to firmly clamp the tape so that it will not fall off.

[0100] As Figure 19 shown, it is an optional embodiment of the cutting assembly 63. In this embodiment, the cutting assembly 63 is assembled with the indenter assembly 623 and moves together with the indenter assembly 623.

[0101] The cutting assembly 63 includes a mounting base 631, a cutting knife 632, a mounting base slide rail 633, and a cutting knife pushing mechanism 634. The cutting knife 632 is fixedly mounted on the mounting base 631. The mounting base 631 is slidably fitted on the mounting base slide rail 633. The cutting knife pushing mechanism 634 is connected to the mounting base 631. The mounting base 631 is connected to the synchronous belt 622 through a connecting plate. The fixed part of the indenter pushing mechanism 6234 is connected to the fixed part of the cutting knife pushing mechanism 634. The cutting knife pushing mechanism 634 drives the mounting base 631 to slide on the mounting base slide rail 633, so that the cutting knife directly acts on the tape to cut the tape. The cutting knife pushing mechanism 634 usually uses a cylinder. In this embodiment, two cutting knives 632 are provided and act on two groups of tapes to be cut simultaneously.

[0102] The cutting knife 632 of the cutting assembly 63 directly cuts the tape under the push of the cutting knife pushing mechanism 634, with a simple structure and reliable operation.

[0103] As Figure 17 、 Figure 18 shown, optionally, on the indenter slide rail 624 with which the indenter assembly 623 is slidably fitted, the indenter slide rail 624 guides the indenter assembly 623 so that the indenter assembly 623 can move smoothly. Optionally, a clamping assembly 66 is also slidably fitted on the indenter slide rail 624. The clamping assembly 66 is used to receive the tape pulled over by the traction assembly 62.

[0104] Figure 21 shown is an optional embodiment of the tape pasting assembly 64Figure 21 It is a three-dimensional view of the component.

[0105] The tape sticking assembly 64 includes a suction plate 641, a telescopic mechanism 642 and a tape sticking lifting mechanism 643. The suction plate 641 is installed on the moving part of the telescopic mechanism 642, and the telescopic mechanism 642 is installed on the tape sticking lifting mechanism 643. When the tape sticking lifting mechanism 643 moves to the upper position, the suction plate 641 sucks the tape. When the tape sticking lifting mechanism 643 moves to the lower position, the telescopic mechanism 642 drives the suction plate 641 to extend and stick the tape on the side of the battery cell 100. The telescopic mechanism 642 usually adopts a cylinder.

[0106] Through the cooperation of the telescopic mechanism 642 and the tape sticking lifting mechanism 643, the tape sticking assembly 64 realizes sticking the tape on the side of the battery cell 100, which can replace manual labor and improve efficiency.

[0107] Optionally, the tape sticking lifting mechanism 643 includes a motor 6431, a connecting plate 6432, a cam plate 6433 and a lifting cam 6434. The connecting plate 6432 is connected to the output shaft of the motor 6431, and the cam plate 6433 is rotatably connected to the connecting plate 6432 through the lifting cam 6434; the telescopic mechanism 642 is installed on the cam plate 6433. The motor 6431 drives the connecting plate 6432 to rotate to drive the tape sticking assembly 64 to move up and down.

[0108] The tape sticking lifting mechanism 643 combines the motor 6431 with the lifting cam 6434, which occupies a small space and has a low cost. Using the motor 6431 as the driving device increases the speed.

[0109] Optionally, the tape sticking assembly 64 further includes a guiding mechanism 644. The guiding mechanism 644 includes a guiding slide rail 6441 and a sliding plate 6442. The sliding plate 6442 is slidably connected to the guiding slide rail 6441, and the sliding plate 6442 is installed on the telescopic mechanism 642.

[0110] The tape sticking assembly 64 realizes smooth lifting through the guiding of the guiding mechanism 644, ensuring the accuracy of the tape sticking action.

[0111] Optionally, the tape sticking assembly 64 further includes a pressing component 645. The pressing component 645 is arranged at both ends of the suction plate 641 and is used to press the tape on the suction plate 641 to prevent the head of the tape from sticking to the clamping mechanism. The pressing head of the pressing component 645 can rotate 90 degrees through the control of a cylinder. When the suction plate 641 sucks the tape, the pressing component 645 is not in front of the suction plate 641 and will not affect the suction. After the suction, the cylinder of the pressing component 645 drives the pressing head to press down.

[0112] Such as Figure 9 、 Figure 10As shown, optionally, the adhesive portion 60 further includes a lifting mechanism 65. After the battery cell is conveyed to the adhesive application station, the lifting mechanism 65 is configured to lift the battery cell 100 to be adhesively applied on the transfer platform 30 to the adhesive application position of the adhesive portion 60. By lifting the battery cell 100 to the adhesive application position by the lifting mechanism 65, necessary preparations are made for applying adhesive to the battery cell.

[0113] Figure 22 , Figure 23 Shown is an optional embodiment of the lifting mechanism 65. Figure 22 It is a perspective view of this component. Figure 23 It is a front view of this component.

[0114] The lifting mechanism 65 includes a first lifting mechanism 651, a second lifting mechanism 652 and a top plate 653. The top plate 653 is located above the first lifting mechanism 651; the second lifting mechanism 652 is installed below the first lifting mechanism 651, and the first lifting mechanism 651 is installed on the movable part of the second lifting mechanism 652. Alternatively, the second lifting mechanism 652 is installed between the first lifting mechanism 651 and the top plate 653, the second lifting mechanism 652 is installed on the movable part of the first lifting mechanism 651, and the top plate 653 is installed on the movable part of the second lifting mechanism 652. The battery cell 100 on the transfer platform 30 rises to the adhesive application position under the lifting of the first lifting mechanism 651 and / or the second lifting mechanism 652. The first lifting mechanism 651 and the second lifting mechanism 652 generally adopt electric cylinders and / or air cylinders.

[0115] Two lifting mechanisms 65 are adopted. One is for rapid rising to improve efficiency, and the other is for slow lifting to avoid the top plate 653 impacting the battery cell 100 and ensure the accuracy of the action.

[0116] As Figure 1 , Figure 2 Shown, after the battery cell 100 is adhesively applied in the adhesive portion 60, it is driven by the rotating portion 40 to rotate from the adhesive application position to the flattening position, that is, at the rolling flat portion 70. The rolling flat portion 70 is used to roll the tape flat onto the upper surface of the battery cell.

[0117] Figure 24 , Figure 25 Shown is an optional embodiment of the rolling flat portion 70. Figure 24 It is a perspective view of this component. Figure 25 is Figure 24 the front view of.

[0118] The rolling flat portion 70 includes a rolling flat translation mechanism 71 and a rolling flat mechanism 72; the rolling flat translation mechanism 71 is configured to drive the rolling flat mechanism 72 to reach or move away from the flattening position of the battery cell 100 on the transfer platform 30; the rolling flat mechanism 72 is installed on the rolling flat translation mechanism 71 and is configured to paste and flatten the un-pasted part of the tape attached to both sides of the battery cell 100 on the transfer platform 30 onto the upper surface of the battery cell 100.

[0119] The rolling and translation mechanism 71 includes a translation driving mechanism 711, a translation mounting plate 712 and a translation guide rail 713. The translation driving mechanism 711 is mounted on the translation mounting plate 712, and the rolling mechanism 72 is mounted on the movable part of the translation driving mechanism 711; the rolling and translation mechanism 71 drives the rolling mechanism 72 to translate. The translation driving mechanism 711 usually adopts a cylinder.

[0120] The rolling and translation mechanism 71 drives the rolling mechanism 72 to move to the leveling position to complete the leveling action of the cell tape. The structure is simple, the levelness is good, and the rolling effect is good; the rolling and translation mechanism 71 is guided by the translation guide rail 713 to make the rolling mechanism 72 lift smoothly and ensure the accuracy of the action.

[0121] As Figure 26 shown, the rolling mechanism 72 includes a rolling mounting plate 721, a roller 723, a roller mounting bracket 722 and a roller driving mechanism 724. The roller 723 is rotatably mounted on the roller mounting bracket 722, and the roller mounting bracket 722 is hinged on the rolling mounting plate 721 and can rotate around the hinge point. The roller driving mechanism 724 is fixedly connected to the rolling mounting plate 721, and the movable part of the roller driving mechanism 724 is fixedly connected to the roller mounting bracket 722. When the roller driving mechanism 724 retracts, the roller 723 is at a high position, and when it extends, the roller 723 is at a low position. When performing the rolling action, the roller 723 is at a low position. The roller driving mechanism 724 usually also adopts a cylinder.

[0122] Optionally, there are two sets of the rolling mechanism 72 and the rolling and translation mechanism 71 respectively. The two sets of rollers 723 are installed side by side on the translation guide rail 713; the two rollers 723 approach or move away from each other respectively under the drive of their respective corresponding translation driving mechanisms 711, and the two rollers 723 descend or rise respectively under the drive of their respective corresponding roller driving mechanisms 724.

[0123] The rolling mechanism 72 adopts a rotatable roller 723, which has low running resistance and will not interfere with the cell; the rolling mechanism 72 adopts two rollers 723, which act on the tapes on both sides of the cell 100 at the same time, can shorten the leveling time and improve the work efficiency.

[0124] The operation process of the rolling part 70 is as follows:

[0125] 1. The roller driving mechanism 724 extends, the roller 723 is at a low position, and contacts the upper surface of the clamping plate 32 of the transfer platform 30;

[0126] 2. The translation driving mechanism 711 acts to translate the roller 723 from the upper surface of the clamping plate 32 to the upper surface of the cell to complete the tape rolling;

[0127] 3. The roller driving mechanism 724 retracts, and the roller 723 returns to the high position;

[0128] 4. The translation driving mechanism 711 retracts, and the roller 723 returns to its original position.

[0129] As Figure 1 , Figure 2 shown, after the cell 100 is flattened by the flattening tape in the flattening part 70, it is driven by the rotating part 40 to rotate from the flattening position to the loading and unloading position, and the cell 100 is transported from the rotating part to the discharging part 80 by the rotating transportation part 20. Thus, a working cycle is completed, that is, from cell loading, to tape sticking, to flattening, to unloading.

[0130] The structure of the discharging part 80 is the same as that of the loading part 10, and will not be described in detail here.

[0131] The above has described the present invention in sufficient detail with a certain particularity. Those of ordinary skill in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of the present invention should fall within the protection scope of the present invention. The scope of protection required by the present invention is defined by the claims described, rather than by the above descriptions in the embodiments.
