[0002] During the battery pack processing, it is often necessary to attach multiple battery cells together to form a battery cell module, and then attach the battery cell module to the terminal, partition, etc. before welding.

[0003] When assembling the battery cell module, it is necessary to ensure that the surfaces of the multiple battery cells remain coplanar, that is, after assembly, the bottom surface, top surface and side surface of each battery cell are coplanar, so as to ensure that the subsequent battery cell module can be fully contacted with other components such as partitions and electrodes during attachment and welding to ensure stable bonding and welding.

[0004] However, the existing attachment operation is mainly manual assembly. Although the end face of the battery cell can be positioned with the help of a certain jig, the limited structure of the jig brings great obstacles to the operation of the staff, affecting the work efficiency. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems existing in the prior art and to provide a battery cell module assembly and molding machine, an assembly method thereof and a battery cell module assembly and molding system.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] The battery module assembly forming machine comprises a carrier, on which a

[0008] A placing seat, wherein a limiting surface and a fixing device are arranged on the table top at the first end thereof, wherein the limiting surface is parallel to the end surface of the table top, and the fixing device has a structure for fixing an object against the limiting surface on the table top;

[0009] The pasting device comprises a grabbing clamping claw, which can move linearly from one end of the placing seat to the other end, and can reciprocate in a direction perpendicular to the placing seat.

[0010] Preferably, in the battery cell module assembly forming machine, the grabbing claw includes a clamping cylinder located below the table plate and two clamping bodies driven by the clamping cylinder and located on both sides of the table plate and extending to above the table plate.

[0011] Preferably, in the battery cell module assembly forming machine, the clamping body includes a support frame, and a clamping plate is provided on the support frame so as to be reciprocally movable relative to the support frame along the moving direction of the clamping body. The clamping plate is connected to a trigger member, and the trigger member is directly opposite to a photoelectric sensor fixed on the support frame. Under normal circumstances, the trigger member is not within the sensing range of the photoelectric sensor.

[0012] Preferably, in the battery core module assembly forming machine, the two clamping bodies are provided with sensors located outside the clamping surfaces thereof.

[0013] Preferably, in the battery cell module assembly forming machine, a laser sensor is disposed above the second end of the platform on the outer side thereof.

[0014] Preferably, in the battery cell module assembly forming machine, a fastening mechanism is provided on the outer side of the second end of the table, and the fastening mechanism includes a pressing plate located above the table and parallel to the limiting surface, and the pressing plate can be reciprocated along the extension direction of the table to the top of the table.

[0015] Preferably, in the battery module assembly forming machine, the pressing plate is floatingly connected to a fastening driving mechanism that drives its movement.

[0016] Preferably, in the battery module assembly forming machine, the placement seat, limiting surface, fixed clamping claw and pasting device are multiple and the number is matched, and some of the multiple pasting devices share the same attachment moving device that drives the grabbing clamping claw to move.

[0021] S300, the grabbing clamp drives the battery cell to move toward the limit surface until the battery cell and the limit surface maintain a predetermined gap, the grabbing clamp stops moving toward the limit surface, and then moves downward;

[0022] S400, the gripping claw continues to move toward the limiting surface until the battery cell is in contact with the limiting surface;

[0023] S500, fixing the battery cell with a fixing claw;

[0024] S600, the gripping claws are reset, and steps S100-S400 are repeated to sequentially bond the multiple battery cells together.

[0025] The advantages of the technical solution of the present invention are mainly reflected in:

[0026] This solution is ingeniously designed. By setting a limiting surface on the placement seat, the battery cell can be effectively positioned and supported.

The lifting structure is located under the placement seat, the structural layout is reasonable, the equipment is more compact, and it occupies less space.

[0028] The clamping plate can be translated, which can effectively avoid hard contact between the battery cell and the limit surface, thereby protecting the battery cell and improving safety. Combined with the slot-type photoelectric and trigger components, it can effectively control the stop of the servo system, avoid damage caused by overvoltage of the battery cell, and further improve safety.

[0029] This solution further adopts a fastening mechanism after pasting, and through the floating pressing plate, it can avoid hard contact between the pressing plate and the battery cell while ensuring the pressing, reduce the risk of battery cell damage caused by impact, and improve the yield rate.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0047] The battery cell module assembly forming machine disclosed in the present invention is explained below in conjunction with the accompanying drawings. It is used to sequentially bond multiple battery cells into a battery cell module. Of course, in other embodiments, it can also be used in other application fields that require multiple components to be assembled into one.

[0048] As attached Figure 1 , Attachment Figure 2 As shown, the battery module assembly machine includes a carrier 00, a placement seat 01, a limiting surface 02, a fixing device 03 and a pasting device 04, the carrier 00 is used to provide support for the placement seat 01 and the pasting device 04, the placement seat 01 is used to provide support for the battery cell and also provide support for the fixing device 03; the limiting surface 02 is used to provide positioning for the first battery cell and provide support for subsequent battery cells to be attached one by one; the fixing device 03 is used to clamp and fix the first battery cell moved to the limiting surface 02 to prevent displacement; the pasting device 04 is used to move the battery cells on the placement seat 01 one by one to the limiting surface 02 for attachment.

[0049] Specifically, as attached Figure 1 As shown, the carrier 00 may be any known structure capable of providing support, for example, it may be a frame 001 constructed of a plurality of profiles, and a receiving plate 002 is provided on the top of the frame 001 .

[0050] As attached Figure 1 , Attachment Figure 2 As shown, at least one placement seat 01 is provided on the receiving plate 002, and the placement seat 01 includes two supports 014, and a table 010 is mounted on the two supports 014. The table 010 is in a flat state, that is, it is parallel to the installation base of the device. The table 010 includes a loading plate 015 and a main table 016. The loading plate 015 is used to place a battery cell to be pasted. It is a flat plate and is located at the second end 012 of the table 010. The top surface of the loading plate 015 is provided with a stopper 013 close to the second end, and the top surface of the loading plate 015 is slightly lower than the top surface of the main table 016. A groove 017 extending from one end to the other end is formed in the middle of the top surface of the main platform 016, and a plurality of blocks 018 are arranged on both sides thereof. The blocks 018 have side blocks 019 extending to the top surface of the platform 010, and the spacing between the side blocks 019 is slightly larger than the length of the battery cell, so that the battery cell located on the platform can be limited.

[0051] As attached Figure 2 -Attached Figure 4 As shown, the table 010 is provided with the limiting surface 02 located at the first end 011 thereof, the limiting surface 02 is perpendicular to the length direction of the table 010 (the direction extending from the first end of the table to the second end), the limiting surface 02 is the end surface of the two limiting blocks 021 facing the second end 012 of the table 010 and coplanar, and the two limiting blocks 21 are arranged in two gaps and parallel to the vertical plate 020 on the table 010. Of course, in other embodiments, the two limiting blocks 021 can also be a limiting plate.

[0052] As attached Figure 2 -Attached Figure 4 As shown, the table 010 is provided with a fixing device 03 located at the first end 011 thereof, and the fixing device 03 can be implemented in various feasible ways. In a feasible embodiment, the fixing device 03 includes a group of vacuum adsorption holes (not shown in the figure) formed on the table 010, and the vacuum adsorption holes are connected to a vacuum extraction device (not shown in the figure), so that the battery cell can be adsorbed on the table by the vacuum adsorption force and abut against the limit surface.

[0053] In another feasible embodiment, the fixing device 03 is provided with a pressing mechanism (not shown in the figure) on the top of the platform 010, and the pressing mechanism applies downward pressure to the battery cell through a liftable pressing plate to fix it on the platform 010.

[0054] In another feasible embodiment, as shown in the attached Figure 3 -Attached Figure 5 As shown, the fixing device 03 is a fixed clamp, and the two clamping parts 030 of the fixed clamp are located on the inner side of the limiting surface 02 (the side facing the second end of the table 010), the two clamping parts 030 are close to the top surface of the table 010, and the two clamping parts 030 reciprocate along the width direction of the placement seat 01, and the two clamping parts 030 are driven by a clamping cylinder 031 to clamp and release, and the clamping cylinder 031 is fixed on the table 010 and is located on the outer side of the limiting surface 02.

[0055] As attached Figure 2 , Attachment Figure 5 As shown, the pasting device 04 includes a grabbing claw 040 , and the grabbing claw 040 can move linearly from one end of the placement seat 01 to the other end, and can reciprocate in a direction perpendicular to the placement seat 01 .

[0056] As attached Figure 5 As shown, the grabbing clamp 040 can be suspended above the table top 010. In a preferred embodiment, the grabbing clamp 040 includes a clamping cylinder 041 located below the table top 010 and two clamping bodies 042 driven by the clamping cylinder 041 and located on both sides of the table top 010 and extending to above the table top 010. The clamping cylinder 041 drives the two clamping bodies 042 to reciprocate along the width direction of the table top 010 to achieve opening and clamping.

[0057] As attached Figure 5As shown, the clamping cylinder 041 is arranged on a lifting device 043 that drives it to reciprocate in a direction perpendicular to the table 010. The lifting device 043 includes a lifting platform 0431 and a lifting cylinder 0432 that drives it to rise and fall. The lifting cylinder 0432 is fixed on a mounting seat 0433. A guide column 0434 connected to the bottom of the lifting platform 0431 is vertically and slidably arranged on the mounting seat 0433. The mounting seat 0433 is arranged on a linear transfer mechanism 044 that drives it to reciprocate along the length direction of the table 010.

[0058] As attached Figure 5 As shown, the linear transfer mechanism 044 can be any device or structure capable of generating linear movement. Preferably, it includes a linear servo module 0441 and a guide rail 0442 extending along the length direction of the platen 010. The linear servo module 0441 is a known technology and will not be described in detail herein. The movable portion of the linear servo module 0441 is connected to the mounting seat 0433, and the mounting seat 0433 is slidably disposed on the guide rail 0442.

[0059] Furthermore, when the fixing device 03 adopts a fixed clamp, the two clamping surfaces of the grabbing clamp 040 (the surfaces where the grabbing clamp 040 contacts the side surface of the battery cell) and the two clamping surfaces of the clamping portion 030 of the fixing device 03 (the surfaces where the clamping portion 030 contacts the side surface of the battery cell) are respectively coplanar in the clamping state, thereby effectively ensuring the position consistency of each battery cell.

[0060] Since the battery cell is at risk of damage when it is under excessive pressure, in a better structure, such as the attached Figure 6 As shown, the clamping body 042 includes a support frame 0421 , and the support frame 0421 is L-shaped as a whole, with its horizontal portion located below the platform 010 and its vertical portion located outside the two sides of the platform 010 . The support frame 0421 is provided with a clamping plate 0422 which can be reciprocated relative to it along its moving direction, and the clamping plate 0422 is located above the clamping portion 030. Specifically, the support frame 0421 is provided with a track 0423 extending along its moving direction, and the clamping plate 0422 is slidably provided on the track 0423. At the same time, the clamping plate 0422 is also provided with an L-shaped block 0424 located at the inner end of the track 0423 (the end facing away from the limiting surface), and the L-shaped block 0424 is slidably provided with a sliding bolt 0425 extending along the length direction of the table plate 010, the sliding bolt 0425 is connected to the clamping plate 0422, and the outer periphery of the sliding bolt 0425 is provided with a limiting sleeve 0426 located between the clamping plate and the L-shaped block 0424.

[0061] As attached Figure 6As shown, a trigger member 045 is connected to the bottom of the clamping plate 0422 on one side, and the trigger member 045 is opposite to a photoelectric sensor 046 fixed on the support frame 0421. The photoelectric sensor 046 is a slot-type photoelectric sensor, which is located below the clamping plate 0422, and the slot of the slot-type photoelectric sensor is opposite to the trigger member 045. Under normal circumstances, the trigger member 045 is not within the sensing range of the photoelectric sensor 046, that is, the trigger member 045 is closer to the limit surface relative to the photoelectric sensor 046. Therefore, when the battery cell clamped by the clamping plate 0422 contacts the limit surface, the two clamping plates 0422 can drive the trigger member 045 to move toward the photoelectric sensor 046. When the photoelectric sensor 046 senses the trigger member 045, it sends a signal to stop the linear servo module 0441, thereby avoiding damage to the battery cell caused by overvoltage.

[0062] In order to effectively control the transfer of the linear servo module 0441, as shown in the attached Figure 2 As shown, the two clamping bodies 042 are provided with a through-beam sensor 047 located on the outer side thereof (the side close to the first end of the table), and the through-beam sensor 047 is used to determine the position of the front end face (the end face facing the limiting face 02) of the battery cell, so that when the through-beam sensor 047 moves to the previous battery cell and is blocked, it can be accurately known that the subsequent linear servo module 0441 needs to drive the battery cell to continue moving the distance, and, at this time, the linear servo module can be stopped, and a signal can be sent to control the lifting cylinder 0432 of the pasting device 04 to drive the battery cell to descend.

[0063] In addition, in order to determine that the first battery cell moves close to the limiting surface, the movement of the battery cell needs to be stopped to make it descend. Figure 2 As shown, a proximity sensor 048 may also be provided on the inner side of the vertical plate 020. When the battery cell moves to the sensing range of the proximity sensor 048, a signal is sent to stop the linear servo module, and at the same time, the lifting cylinder 0432 drives the battery cell to descend.

[0064] Furthermore, since multiple battery cells need to be attached, in order to accurately know the number of attached battery cells, in a preferred embodiment, Figure 7 As shown, a laser sensor 05 is provided above the second end 012 of the platform 010 on the outside thereof, and the laser emitted by the laser sensor 05 is directed toward the battery cells on the platform 010. When there are battery cells, the laser is blocked so that the distance between the sensor and the battery cells can be known. According to the different measured distances, it can be known how many battery cells have been pasted, so that the servo linear module can be controlled in combination with the corresponding beam sensor.

[0065] Since the pressure applied by the pasting device 04 to the battery cells during pasting is often limited, after all the battery cells are placed on the platen and pre-pasted together, a further pressure mechanism is required to make the pasting of a group of battery cells more firmly. Figure 7 , Attachment Figure 8 As shown, a fastening mechanism 06 is provided on the outer side of the second end 012 of the table top, and the fastening mechanism 06 includes a pressing plate 061 located above the table top 010 and parallel to the limiting surface, and the pressing plate 061 can reciprocate along the length extension direction of the table top 010 to the top of the table top.

[0066] The height of the pressing plate 061 is equivalent to that of the laser sensor 05. In order to avoid affecting the laser sensor 05, a hole (not shown in the figure) is provided in the middle of the pressing plate 061 to avoid the laser of the laser sensor 05. In addition, in order to prevent the pressing plate 061 from making hard contact with the battery cell and causing damage to the battery cell due to overpressure, the pressing plate 061 is connected to a fastening driving mechanism that drives its movement in a floating manner.

[0067] As attached Figure 7 , Attachment Figure 8 As shown, the fastening drive mechanism includes a large cylinder 062 extending along the length direction of the table top 010, and the large cylinder 062 is fixed on a U-shaped groove plate 063, and its movable part is connected to a sliding seat 064 slidably set on the top of the vertical plate 020, and the sliding seat 064 is slidably set on the guide rail 069 on the top of the U-shaped groove plate 063, and is connected to a cross bar 065, and the cross bar 065 is provided with a vertical plate 066 parallel to the pressing plate 061, and the vertical plate 066 is provided with a through hole matching the avoidance hole on the pressing plate 061, and two connecting bolts 067 are vertically and slidably arranged on the vertical plate 066, one end of the connecting bolt 067 is connected to the pressing plate 061, and a floating spring 068 located between the pressing plate 061 and the vertical plate 066 is sleeved on the outer periphery of the connecting bolt 067. Of course, the floating spring can also be replaced by other elastic members, such as multiple metal springs.

[0068] In the above embodiment, only a placement seat 01 is described in conjunction with a limiting surface 02, a fixing device 03, an adhesive device 04, a laser sensor 05 and a fastening mechanism 06, which form a processing station. In a more preferred embodiment, in order to improve the assembly efficiency, as shown in the attached Figure 7As shown, the processing stations are preferably multiple (one group), that is, the placement seats 01 are multiple and arranged side by side, and each placement seat 01 cooperates with a limit surface 02, a fixing device 03, a pasting device 04, a laser sensor 05, and a fastening mechanism 06. In addition, in this multi-station structure, some of the multiple pasting devices 04 can share the same attachment moving device that drives the grabbing clamp 040 to move. For example, when there are six processing stations, the pasting devices 04 of the two middle stations can share a set of servo linear modules, and the two stations on both sides use a servo linear module respectively.

[0069] Furthermore, in the structure of multiple processing stations, as shown in the attached Figure 7 As shown, the laser sensors 05 of multiple processing stations can be arranged at the same height on the same T-shaped frame 08, and the pressing plates of multiple fastening mechanisms 06 can be arranged together on a cross bar 065, and the two ends of the cross bar 065 are respectively connected to the large cylinder.

[0070] Furthermore, after the attachment is completed, it is necessary to cut the material. If there is only one set of multiple processing stations, it is impossible to continue assembling when cutting the material, resulting in a waste of time. Figure 1 , Attachment Figure 7 As shown, the carrier 00 is arranged on a turntable 07 that drives the carrier 00 to rotate. The specific structure of the turntable 07 is a known technology and is not an innovation of the present invention, so it will not be described here. Two groups of processing stations are arranged on the turntable 07, each group of processing stations includes a plurality of processing stations, and each processing station in one group corresponds to each processing station in the other group one by one and is mirror-symmetrical, and their limit surfaces 02 are at opposite ends.

[0071] When the above-mentioned wire module assembly forming machine is used to assemble the battery module, it includes the following steps:

[0072] A battery cell is placed on the loading plate 015 manually or by automated equipment, the protective paper on the adhesive surface of the battery cell facing the limiting surface 02 is not removed, and the adhesive layer on the side of the battery cell facing away from the limiting surface 02 is exposed.

[0073] S100, the clamping cylinder 041 of the grabbing clamp 040 drives the two clamping bodies 042 to move synchronously to clamp and grab the battery cell on the loading plate 015.

[0074] S200, the lifting cylinder 0432 drives the clamping cylinder 041 to lift upward, driving the battery cell clamped by the clamping body 042 to rise and separate from the loading plate 015.

[0075] S300, the linear servo module 0441 starts to drive the grabbing clamp 040 to drive the battery cell thereon to move toward the limit surface 02 as a whole until the battery cell and the limit surface 02 maintain a predetermined gap, and then the linear servo module 0441 stops, and the lifting cylinder 0432 drives the grabbing clamp 040 to move downward to make the battery cell fall onto the main table 016. The gap can be designed as needed and realized by controlling the linear servo module through PLC program settings, and of course, it can also be determined by the signal of the beam sensor.

[0076] S400, the linear servo module 0441 starts again to drive the grabbing claw 040 to continue moving toward the limiting surface 02 until the battery cell is in contact with the limiting surface 02 and then stops.

[0077] S500, at this time, the clamping cylinder 031 of the fixed clamping jaw is started to make the two clamping parts 030 move relative to each other to clamp and fix the battery cell.

[0078] S600, the linear servo module 0441 drives the grabbing claw 040 to reset, and repeats steps S1-S4 to sequentially glue the multiple battery cells together. The two sides of the battery cells subsequently placed on the loading plate 015 are determined as needed to determine whether to set a glue layer, and the protective paper of the tape on the outer side of the outermost battery cell is not torn off. This is not a design point of this solution and will not be elaborated here.

[0079] S700, the large cylinder 062 of the fastening mechanism 06 is started to drive the pressing plate 061 to move toward the battery core, and apply pressure to the outer side of the outermost battery core to make the multiple battery cores adhere and fasten. The fastening mechanism 06 can be reset after fastening for a period of time.

[0080] S800, after the fastening is completed, the clamping cylinder 031 of the fixed clamping jaw is started to open the two clamping parts 030 to release the clamping and fixation of the first battery cell, so that unloading can be carried out.

[0081] Of course, in other embodiments, the battery cell may be first brought into contact with the limiting surface and then lowered onto the platform.

[0082] This solution further discloses a battery module assembly molding system, as shown in the attached Fig. 9 As shown, it includes the above-mentioned battery cell module assembly and forming machine 40 , and also includes a battery cell module surface pretreatment device 10 , a first transfer mechanism 20 , a battery pack assembly device 30 and a second transfer mechanism 50 .

[0083] The cell module surface pretreatment device 10 is used to tear off the protective paper on the tapes at both ends of the assembled cell module and clean the two sides of the cell module, so that the cell module, the terminal and the partition can be assembled into one through the battery pack assembly device 30 later. The first transfer mechanism 20 is at least used to move the cell module treated by the cell module surface pretreatment device to the battery pack assembly device 30, and it can also grab the partition and the terminal from the battery pack partition supply device 60 that supplies the partition with a glue layer on one side and the terminal supply device 70 that supplies the terminal to the battery pack assembly device 30, which can be various feasible transfer devices, such as a six-axis robot. The second transfer mechanism 50 is used to move the cell module assembled by the cell module assembly molding machine 40 to the cell module surface pretreatment device.

[0084] When the entire equipment is running, whether it is the entire system, or a single battery module assembly machine 40, a battery pack assembly device 30 or a battery module surface pretreatment device 10, various control devices, such as PLC, etc., combined with various sensors, such as proximity switches, position switches, etc., can be used to start and stop various motors, cylinders and other components and switch their states. This is a known technology and is not the innovation of this solution, so it will not be elaborated here.

[0085] As attached Fig.10 As shown, the cell module surface pretreatment device 10 comprises a workbench 9000 , on which a cell module support platform 1000 , a cell module locking mechanism 2000 , a paper removal mechanism 3000 and a cleaning mechanism 4000 are arranged.

[0086] The workbench 9000 is used to provide support for other structures. It can be a frame structure composed of various profiles and plates, which is not limited here. In order to facilitate movement, universal wheels are set at the bottom of the workbench 9000. Fig.10 As shown, the battery module support platform 1000 is provided at the top middle position of the workbench 9000. Fig.11 As shown, the battery cell module support platform 1000 is used to place the battery cell module, which includes a support leg 1100, on which a support plate 1200 is horizontally arranged, and a reinforcing plate 1300 and a group of limiting blocks 1400 located on both sides of the long sides of the reinforcing plate 1300 are arranged on the support plate 1200, and the limiting blocks 1400 have ribs extending above the reinforcing plate 1300, and the spacing between the ribs on both sides is equivalent to the width of the battery cell module, so that the width direction of the battery cell can be effectively limited.

[0087] The cell module on the cell module support platform 1000 is fixed on the cell module support platform 1000 via a cell module locking mechanism 2000 . The cell module locking mechanism 2000 may be in various feasible forms.

[0088] In a feasible embodiment, a group of vacuum adsorption holes (not shown in the figure) are formed on the battery cell module support platform 1000, and the vacuum adsorption holes are connected to a vacuum extraction device (not shown in the figure), so that the battery cell module can be adsorbed on the battery cell module support platform 1000 by vacuum adsorption force.

[0089] In another feasible embodiment, a pressing mechanism (not shown in the figure) is provided on the top of the battery cell module support platform 1000, and the pressing mechanism applies downward pressure to the battery cell module through a liftable pressing plate to fix it on the battery cell module support platform 1000.

[0090] However, the structures of the above two embodiments cannot accurately position the battery cell module, and it is necessary to ensure the accuracy of the position of the battery cell module in advance when placing the battery cell module. Therefore, in a more preferred embodiment, as shown in the attached Fig.10 , Attachment Fig.12 As shown, the battery cell module locking mechanism 2000 includes a clamping mechanism 2100 located at both ends (left and right ends) of the battery cell module support platform 1000, each of the clamping mechanisms 2100 includes a pressing plate 2110, the height of the pressing plate 2110 corresponds to the glue-free area above the glue layer of the end face of the battery cell module, the pressing plate 2110 is fixed to a horizontal plate 2130 through an L-shaped stand 2120, the horizontal plate 2130 is slidably arranged on two guide rails 2140 extending along the length direction of the battery cell module support platform through two sliders at the bottom thereof, the horizontal plate 2130 is connected to a moving device 2150 that drives it to slide along the guide rail 2140, and the moving device 2150 is fixed to the top surface of the workbench 9000. The moving device 2150 is preferably located on the horizontal plate 2130, which can be a linear motor or a linear module or a structure consisting of a motor and a lead screw that can produce linear movement; of course, it can also be a cylinder, an oil cylinder, an electric push rod, etc. The minimum spacing between the two pressing plates 2110 of the clamping mechanism 2100 is the same as the length of the battery module, so that the two pressing plates 2110 can effectively position and fix the battery module.

[0091] After the cell module locking mechanism 2000 fixes the cell module, paper removal and cleaning operations can be performed. The paper removal operation refers to tearing off the protective paper (centrifugal paper or centrifugal film) on the glue layer at both ends of the cell module, and the paper removal operation is performed by the paper removal mechanism 3000. The cleaning operation refers to cleaning the two sides of the cell module to remove dirt, and the cleaning operation is performed by the cleaning mechanism 4000.

[0092] As attached Fig.12 , Attachment Fig.13 As shown, the paper removal mechanism 3000 includes at least one portion located outside the end portion 1500 of the battery module support platform 1000 and reciprocatingly movable along the extension direction of the end portion of the battery module support platform 1000, and includes a paper removal clamp 3100, the paper removal clamp 3100 includes a clamp cylinder 3110 and two clamps 3120 driven thereby, the clamp 3120 includes a main body 3121 and a clamp plate 3122, and mutually matching bosses and notches are formed on opposite end surfaces of the two clamp plates 3122, the boss extends in a direction perpendicular to the battery module support platform 1000, and the boss is located at the notch when clamped by the two clamps, so that the head of the protective paper can be stably clamped.

[0093] As attached Fig.12 As shown, the paper removal clamp 3100 is adjustably arranged on a mounting plate 3200. Specifically, the clamp cylinder 3110 of the paper removal clamp 3100 has two screw holes, and the mounting plate 3200 has two mounting holes corresponding to the screw holes on the clamp cylinder 3110, one of which is a round hole 3210, and the other is an arc hole 3220. The clamp cylinder 3110 and the mounting plate 3200 can be connected by bolts, so that the position of the clamp cylinder 3110 can be adjusted by adjusting the position of a mounting hole on the clamp cylinder 3110 in the arc hole 3220. The mounting plate 3200 is connected to a fixed linear motion device 3300, and the linear motion device 3300 can be a device that can generate linear motion, such as a cylinder or an oil cylinder.

[0094] As attached Fig.12 As shown, the linear moving device 3300 is arranged on a driving device 3400 that drives it to reciprocate along the end extension direction of the battery module support platform (1000) (the width direction of the battery module support platform) through a sliding member. The sliding member is slidably arranged on a guide bar 3500 extending along the width direction of the battery module support platform. The driving device 3400 is also a variety of devices that can produce linear movement, such as a cylinder or an oil cylinder. In a preferred embodiment, the driving device 3400 is a linear motor or a linear module, and its two ends extend to the outside of the two long sides of the battery module support platform 1000. At the same time, the driving device 3400 is arranged on the horizontal plate 2130 of the battery module locking mechanism and is located below the pressing plate 2110, so as to move synchronously with the pressing plate 2110.

[0095] In this embodiment, the linear moving device 3300 takes a cylinder as an example. When the cylinder shaft of the cylinder is extended, the two clamping jaws 3120 of the paper removal clamping jaw 3100 are located at one end of the tape on the end face of the battery module and can clamp the head of the protective paper (release paper or centrifugal film) on the tape extending outside the end face of the battery module. When the cylinder shaft of the cylinder is retracted, the paper removal clamping jaw moves the head of the protective paper it clamps away from the end face of the battery module, thereby separating the head of the protective paper from the colloid. Then the driving device 3400 drives the paper removal clamping jaw 3100 to move linearly toward the other end of the protective paper, so that the protective paper can be torn off the glue layer.

[0096] In a further preferred embodiment, in order to prevent the protective paper from lifting the glue layer when removing the paper, in a more preferred manner, as shown in the attached Fig.13 As shown, the moving path (reciprocating direction) of the installation plate 3200 driven by the linear moving device 3300 forms an acute angle with the angle A of the short side of the battery module support platform 1000. This arrangement enables the force direction when tearing off the protective paper to form an acute angle with the glue layer, thereby greatly reducing the separation of the vertical glue layer due to the pulling force when tearing off the protective paper, thereby greatly reducing the risk of lifting the glue layer.

[0097] After the paper removal mechanism 3000 performs the tearing operation, it is necessary to determine whether the protective paper is effectively torn off. Fig.10 As shown, the battery cell module surface pretreatment device also includes a paper removal determination mechanism 5000, which is used to determine whether the protective paper of the tape is torn off. The paper removal determination mechanism 5000 can use various feasible methods to determine whether there is a glue layer. For example, a high-precision distance measuring sensor (laser sensor, etc.) can be used to measure the distance from the sensor to the end face of the battery cell module, so as to determine whether the protective paper is torn off.

[0098] In an optional manner, this is achieved by providing a brightness sensor. Due to the brightness difference between the protective paper and the glue layer, the brightness detected by the brightness sensor can be used to determine whether it is the protective paper or the glue layer.

[0099] In a more preferred embodiment, this is achieved by providing a color mark sensor, which is provided on the paper removal clamp 3100 through a bracket and is located below the pressure plate and moves synchronously with the paper removal clamp 3100, that is, the color mark sensor is also provided on the linear moving device 3300, and the color mark sensor determines whether to tear off the protective paper by identifying the different colors of the white release paper and the black glue layer.

[0100] Furthermore, after the paper removal mechanism 3000 tears off the protective paper, the protective paper needs to be discarded before the next tearing operation can be carried out. Fig.10As shown, in order to effectively collect the protective paper and avoid the torn protective paper from polluting the working environment, a protective paper collector 6000 is provided at one end below the paper removal mechanism 3000. The protective paper collector 6000 includes a feed hopper 6100 and a collection box 6200. The protective paper collector 6000 is preferably located directly below the position to which the paper removal claws of the paper removal mechanism 3000 move when tearing off the protective paper, so that the paper removal claws holding the protective paper can be opened immediately to discard the protective paper into the protective paper collector 6000.

[0101] Since the weight of the protective paper is relatively light, it is easily affected by airflow and scattered everywhere. In view of this, in a more preferred embodiment, as shown in the attached Fig.10 As shown, a purge device 7000 for forming an airflow toward the protective paper collector 6000 is arranged above the paper removal mechanism 3000. The purge device 7000 can be various devices that can generate an airflow flowing in a certain direction, such as a blower, a fan, etc., which is not limited here.

[0102] As attached Fig.10 , Attachment Fig.13 As shown, the cleaning mechanism 4000 includes a cleaning device 4100 located outside the side 1600 (long side) of the battery module support platform 1000, and the cleaning device 4100 can at least reciprocate along the side extension direction of the battery module support platform 1000, and it can move from one end of the battery module support platform 1000 to the other end, so that the long side of the battery module on the battery module support platform 1000 can be cleaned.

[0103] The cleaning device 4100 can be various cleaning equipment. In one feasible embodiment, the cleaning device is a nozzle connected to a high-pressure gas source, so that it can be blown; in another feasible embodiment, the cleaning device 4100 is a nozzle connected to a dry ice cleaning machine, so that dry ice cleaning can be performed. In another feasible embodiment, the cleaning device 4100 is a cleaning head of an ultrasonic cleaning machine, so that ultrasonic cleaning can be performed.

[0104] In a preferred embodiment, the cleaning device 4100 may also have a plasma cleaning gun, and in a more preferred embodiment, there are two plasma cleaning guns, and the plasma cleaning guns have a height difference and are staggered in the longitudinal direction, so that the two plasma cleaning guns can completely cover the side of the battery cell module to complete the complete cleaning of one side of the battery cell module in one cleaning process.

[0105] Of course, in other embodiments, there may be only one plasma cleaning gun, and the entire side of the battery cell module can be covered by moving the cleaning device 4100 up and down.

[0106] As attached Fig.13 , Attachment Fig.14 As shown, the cleaning device 4100 is connected to a cleaning movable device 4200 which drives it to reciprocate along the length direction of the battery module support platform. The cleaning movable device 4200 can also be various devices that can produce linear movement, such as a cylinder, an oil cylinder, etc., preferably a linear motor or a linear module or a structure composed of a motor and a lead screw. The cleaning movable device 4200 drives the cleaning device 4100 to move from the outside of one end of the battery module support platform to the outside of the other end.

[0107] Furthermore, during cleaning, the head of the cleaning device 4100 needs to be kept close to the side of the battery module. Fig.13 , Attachment Fig.14 As shown, the head of the cleaning device 4100 interferes with the placement of the battery module on the battery module support platform 1000 to a certain extent, so in a more optional manner, the cleaning device 4100 can also be reciprocated along the width direction of the battery module support platform. Specifically, the two cleaning devices 4100 are arranged on an upper L-shaped member 4300, and a slide rail 4400 extending along the width direction of the battery module support platform is arranged at the bottom of the L-shaped member 4300, and the slide rail 4400 is slidably arranged on a guide block, and the L-shaped member 4300 is connected to a push-pull cylinder 4500 that drives it to reciprocate along the extension direction of the slide rail 4400, and the push-pull cylinder 4500 and the guide block 4800 are both arranged on a bottom plate 4600, and the bottom plate 4600 is fixed on the movable part of the cleaning mobile device 4200, and the bottom plate 4600 is slidably arranged on a track 4700 extending along the length direction of the battery module support platform.

[0108] On the other hand, the tail end of each cleaning device 4100 is connected to a cable or pipe (not shown in the figure), and the cable or pipe will be in a drooping state under the action of gravity, which may cause abnormalities (leakage or damage, etc.) in the connection position with the cleaning device 4100. Therefore, the cable or pipe is suspended on a suspension rope, and the suspension rope enables the cable or pipe to maintain a similar height or an approximately coaxial state with the cleaning device 4100.

[0109] Further, as attached Fig.10 , Attachment Fig.15As shown, a code scanning mechanism 8000 is also arranged on the base plate 4600, and the code scanning mechanism 8000 includes a vertical pole 8100 arranged on the base plate 4600, a loading platform 8200 is arranged on the vertical pole 8100, and a cylinder 8300 is arranged on the loading platform 8200. The cylinder axis of the cylinder 8300 extends along the width direction of the battery module support platform and is connected to a frame 8600. The frame 8600 is provided with a code scanner 8400 with a lens facing downward and a light source 8500 with a light-emitting surface facing downward.

[0110] In the above structure, there is only one paper removal mechanism 3000 and one cleaning mechanism 4000, so only one end surface of the battery cell module can be removed and one side surface can be cleaned at one time.

[0111] After one paper removal and cleaning operation, the battery module can be horizontally rotated 180 degrees by manual or automated equipment to remove paper from the other end face and clean the other side face.

[0112] When automated equipment is used to realize the rotation of the battery cell module, it can be realized in different ways. For example, in one feasible way, the battery cell module support platform can be a self-rotating structure, and the battery cell module support platform is connected to a rotating drive mechanism that drives its self-rotation. In this case, the battery cell module support platform can be a circular table, and a rotating shaft (not shown in the figure) is coaxially connected to its bottom, and the rotating shaft is connected to the inner hole of the bearing on the workbench, and the rotating shaft is directly or through a transmission structure connected to a motor that drives its self-rotation. Of course, in other embodiments, the battery cell module support platform can also be directly connected to a reduction motor that drives its self-rotation.

[0113] In another embodiment, a mobile robot, such as a six-axis robot, may be arranged on the workbench to rotate the battery cell module 180 degrees by the robot. This is a known technology and will not be described in detail.

[0114] In other embodiments, the cleaning mechanism and the paper removal mechanism can even be rotated 180°. The specific rotation structure here is the prior art and has a complex structure to implement. It is not a design point of this solution and will not be described in detail here.

[0115] In a preferred embodiment, as shown in the attached Fig.10 , Attachment Fig.13As shown, there are two paper removal mechanisms 3000 and two cleaning mechanisms 4000. Under normal circumstances, the two paper removal clamps 3100 of the paper removal mechanisms 3000 are diagonally distributed, and the two cleaning devices 4100 of the cleaning mechanisms 4000 are diagonally distributed, and the diagonals of the two paper removal clamps 3100 intersect with the diagonals of the two cleaning devices 4100. Therefore, when the four components work at the same time, they can effectively avoid interference with each other and improve the matching degree between each other, which is beneficial to improving the working rhythm and improving efficiency.

[0116] When the above-mentioned wire module surface pretreatment device is used to pretreat the surface of the battery cell module, the following process is included;

[0117] S01, manually or through automated equipment, place the battery cell module with the tape on the battery cell module support platform 1000, and make the two ends of the battery cell module face the battery cell module locking mechanism 2000.

[0118] S02, the two moving devices 2150 of the battery cell module locking mechanism 2000 drive the two pressing plates 2110 to move toward each other so as to position and fix the battery cell module.

[0119] S03, the two linear moving devices 3300 of the paper removal mechanism 3000 drive the paper removal clamps 3100 to extend forward, and then the clamp cylinder 3110 starts to drive the two clamps 3120 to clamp the heads of the protective paper on the tape at both ends of the battery cell module. Then, the linear moving device 3300 drives the paper removal clamps 3100 to retract and separate the heads of the protective paper from the adhesive layer; then the two driving devices 3400 drive the two paper removal clamps 3100 to move toward each other, thereby tearing off the two protective papers.

[0120] S04, while the paper removal mechanism 3000 is working, the cylinder shafts of the push-pull cylinders 4500 of the two cleaning mechanisms 4000 are extended to make the two cleaning devices 4100 close to the two sides of the battery cell module, and the cleaning devices 4100 start to clean. Then the two cleaning moving devices 4200 drive the cleaning devices 4100 connected to them to move toward each other to achieve simultaneous cleaning of the two sides of the battery cell module.

[0121] S05, after the two paper removal clamps 3100 move to the top of the protective paper collector 6000, the clamp cylinder opens the two clamps to untie the protective paper, and the protective paper is blown into the protective paper collector 6000 under the airflow of the purge device 7000. After the paper removal and cleaning are completed, the components are reset.

[0122] In addition, when the paper removal determination mechanism 5000 determines that the protective paper has not been torn off, an alarm may be issued to remind the staff to manually tear off the protective paper before unloading.

[0123] There are many implementation methods of the present invention, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
