Description

Technical Field

[0001] The present invention relates to the technical field of battery production equipment, and particularly to an automatic square battery cell gluing device. Background Art

[0002] The battery module is an important component in the battery pack. Existing battery modules include multiple groups of battery cells. During the production of the battery module, multiple battery cells need to be stacked and spliced in sequence. Therefore, it is necessary to apply glue on the top of each battery cell, and adhere it to the battery cell in the form of a glue strip or sheet glue, so as to stack and bond multiple groups of battery cells to form a battery module. Existing battery cells are mainly encapsulated in three forms: cylindrical, square, and soft pack. And generally, a release paper is provided outside the existing glue application. The release paper is a type of anti-adhesive paper, also known as separator paper, anti-adhesive paper, and silicone oil paper; among them, the main function of the release paper is to prevent prepregs from sticking to each other. The release paper mainly consists of three layers. The first layer is the base paper, the second layer is the coating, and the third layer is the silicone oil.

[0002]

[0003] During the glue application process of existing square battery cells, manual glue application is mainly adopted. Before applying glue on the top of the square battery cell, the whole film or four glue strips can be used for glue application according to actual production requirements. When using the whole film for glue application, it is necessary to ensure that the four sides of the film are aligned with the four sides of the top of the square battery cell. When using glue strips for glue application, it is necessary to ensure that each glue strip can be respectively aligned with the periphery of the four sides of the top of the square battery cell for attachment, that is, four glue strips are used to form a "mouth" shape around the top of the square battery cell. The method of applying glue to the square battery cell with glue strips can leave a gap between the adjacent sides of the stacked battery cells compared with the method of applying glue to the square battery cell with the whole film, which can improve the heat dissipation effect between the battery cells; however, whether using glue strips or the whole film, it is necessary to peel off the release paper on both sides of the film. If manual glue application is used, not only the working efficiency is slow, but also it is impossible to ensure that the adhesion positions of each glue strip are aligned with the periphery of the four sides of the top of the square battery cell one by one. Once the position of the glue strip of a single battery cell is inclined or deviated, it will cause the fitting positions of multiple battery cells to be inclined and deviated, resulting in the inability of multiple battery cells to be stacked and leveled completely, thereby affecting the production quality of the battery module. If a mechanical glue application method is used to perform the glue application operation on the battery cell, although the working efficiency can be improved compared with manual glue application, the existing glue application equipment can only perform glue application work on the battery cell with the whole film or a single glue strip at a single station, that is, the single glue strip is sequentially attached directly above the square battery cell one by one, and the existing glue application equipment also needs to cooperate with manual peeling of the release paper on the glue strip, resulting in a relatively low overall automation efficiency. Moreover, the existing overall glue application equipment cannot perform glue application operations on battery cells of different sizes during the glue application process of the glue strip, and the applicable range is low.

[0004] The Chinese invention patent application with the reference publication number "CN105375058A" and the name "Cell Gluing Machine" discloses a technical solution of "a cell gluing machine for gluing cells, including a pre-gluing mechanism, a full-gluing mechanism, a transfer manipulator and a cell fixing mechanism. The pre-gluing mechanism includes: a glue feeding device, a glue sucking device, a glue pressing device and a glue cutting device. The full-gluing mechanism includes: a full-gluing sliding block, a lower gluing workpiece fixedly arranged on the full-gluing sliding block, and an upper gluing workpiece rotatably arranged on the full-gluing sliding block. A roller is arranged on the upper gluing workpiece. The cell fixing mechanism includes: a support frame, a rotating shaft rotatably arranged on the support frame, a fixing block fixedly arranged on the rotating shaft, and a fixing cylinder. The rotating shaft and the fixing cylinder are engaged through gears and racks. The pre-gluing mechanism has a pre-gluing station, the full-gluing mechanism has a full-gluing station, and the transfer manipulator transfers the cell at the pre-gluing station to the full-gluing station". Although this technical solution can realize the automatic gluing action on the cell, it fails to realize the full-automatic fitting action of the rubber strip on the square cell, thus resulting in low automation efficiency.

[0005] Therefore, how to realize the full-automatic gluing of square cells is a technical problem that needs to be solved by technicians at present. Summary of the Invention

The lifting column 412 is movably arranged on the cross arm of the robotic arm 411, and one side of the glue picking suction plate 42 is arranged directly below the lifting column 412. The moving range of the glue picking suction plate 42 can be controlled by the moving mechanism 41. Therefore, when it is necessary to pick up the glue from the glue supply device 3, the moving mechanism 41 can drive the glue picking suction plate 42 to move to the glue supply device 3, and the film is adsorbed by the glue picking suction plate 42 to complete the automatic glue picking operation.

[0061] The glue feeding device 6 includes a mounting flat plate 61 and a fixed top plate 62. The fixed top plate 62 is located directly above the mounting flat plate 61, and one side of the mounting flat plate 61 is fixed to the top of the placement flat plate 2. A glue separating mechanism 7 is slidably arranged on the other side of the mounting flat plate 61, and a driving mechanism 611 is also arranged on the mounting flat plate 61. The power output end of the driving mechanism 611 is in transmission connection with the bottom of the glue separating mechanism 7. Therefore, the moving distance of the glue separating mechanism 7 can be controlled by the driving mechanism 611, so that one end of the fixed top plate 62 is close to the glue supply device 3. A glue discharging suction hole is provided at one end of the fixed top plate 62, and the other end of the fixed top plate 62 is close to the outside of the transport plane 1, and a glue feeding suction hole is provided at the other end of the fixed top plate 62. The driving mechanism 611 can drive the glue separating mechanism 7 to move to the glue discharging suction hole to clamp and pick up the film on the glue discharging suction hole, and then move to the glue feeding suction hole again to make the film be on the glue feeding suction hole, so as to facilitate the gluing device 5 to grab the film for the gluing operation, and the glue separating mechanism 7 can also perform the glue separating operation on the glue strip on the film (the specific glue separating operation can refer to Embodiment 3);

[0062] The glue sticking device 5 includes a displacement mechanism 51 and a connecting plate 52. One side of the connecting plate 52 is arranged on the power output end of the displacement mechanism 51. Therefore, the displacement mechanism 51 can be used to control the moving range of the connecting plate 52 so that two strip-shaped glue sticking suction plates 520 are slidably arranged on one side of the connecting plate 52. A plurality of adsorption through holes are arranged at the bottom of the glue taking suction plate 42 and the two strip-shaped glue sticking suction plates 520; therefore, the displacement mechanism 51 can be used to drive the connecting plate to move so that the strip-shaped glue sticking suction plates 520 are located directly above the glue supply suction holes to adsorb the adsorption film and / or the adhesive strip, and the displacement mechanism 51 can be used to drive the connecting plate to move again so that the strip-shaped glue sticking suction plates 520 are aligned with the battery cells on the transport plane 1, and then the automatic glue sticking action is performed.

[0063] It should be noted that the glue supply device 3 includes a material supporting plate 31 and a fixed vertical plate 32. The material supporting plate 31 is movably arranged on one side of the fixed vertical plate 32. A lifting mechanism 33 is arranged on the other side of the fixed vertical plate 32, and the power output end of the lifting mechanism 33 is connected to one side of the material supporting plate 31. Therefore, the lifting mechanism 33 can be used to control the lifting height of the material supporting plate 31, and the other side of the material supporting plate 31 can also be used to place the film; the lifting mechanism 33 can drive the material supporting plate 31 to rise, and then the film on the material supporting plate 31 can be close to the glue taking device 4, so that the glue taking suction plate 42 of the glue taking device 4 can absorb and take the film.

[0064] The lifting mechanism 33 includes a lifting motor 331 and a lifting screw rod 332, and the power output end of the lifting motor 331 is transmission-connected to one end of the lifting screw rod 332. A lifting support plate 333 is movably arranged on the outside of the lifting screw rod 332 so that one side of the lifting support plate 333 faces one side of the material supporting plate 31. Therefore, the lifting mechanism 33 can be used to control the lifting height of the lifting support plate 333. When the lifting motor 331 drives the lifting screw rod 332 to rotate, during the rotation of the lifting screw rod 332, the lifting support plate 333 can be lifted and lowered on the lifting screw rod 332, that is, when the power output end of the lifting motor 331 can be used to perform forward and reverse rotation, the lifting screw rod 332 is driven to rotate forward and reversely, when the lifting screw rod 332 rotates forward, the lifting support plate 333 can be driven to rise, and when the lifting screw rod 332 rotates reversely, the lifting support plate 333 can be driven to descend, thereby effectively realizing the automatic glue supply action, so that the stacked films can be supplied to the glue taking device 4 in sequence.

[0065] It is particularly noted that in order to prevent the adhesive strip from adhering to the equipment components, since the adhesive strip has a certain stickiness after peeling off the release paper, the components in contact with the adhesive strip, such as the adsorption through holes of the adhesive suction plate 42, the adhesive discharge suction holes, and the surfaces of the adhesive supply suction holes are coated with an anti-stick coating to prevent the adhesive strip from sticking and being difficult to fall off, thereby affecting subsequent work.

[0066] Embodiment 2 is to achieve the automatic gluing operation on two battery cells at two workstations to improve work efficiency and is applicable to continuous production. In this embodiment: There is a transport plane 1 for transporting battery cells; a placement flat plate 2; two glue supply devices 3 for supplying film; a glue picking device 4; and two gluing devices 5. The glue supply device 3 and the transport plane 1 are both located outside the placement flat plate 2, the glue supply device 3 is adjacent to the glue picking device 4, the two gluing devices 5 are both located directly above the transport plane 1, two glue feeding devices 6 are arranged on the top of the placement flat plate 2, the two glue feeding devices 6 are close to the two gluing devices 5 one by one, the glue picking device 4 is located between the two glue feeding devices 6, the two glue supply devices 3 are adjacent to each other, and the two glue supply devices 3 correspond to the two glue feeding devices 6 one by one. The two glue supply devices 3 can effectively supply film, and the glue picking device 4 can perform the adsorption and glue picking operation from the two glue supply devices 3 respectively and place the film in the two glue feeding devices 6 respectively. The two glue feeding devices 6 supply the film to the two gluing devices 5 respectively, and then the two gluing devices 5 can perform the automatic gluing operation on the two battery cells on the transport plane 1 respectively, effectively realizing the two-workstation production and improving the work efficiency.

[0067] Regarding the above, it is further supplemented that in order to fix the position of the battery cell after the battery cell is transported and aligned with the gluing device 5 so as to prevent loosening during gluing, there are two conveying tracks under the transport plane 1. The two conveying tracks are adjacent to each other. Limiting devices are arranged on the two conveying tracks, and the two limiting devices are close to the two gluing devices 5 one by one. The limiting device includes a limiting cylinder and a limiting side plate. The limiting side plate is arranged on the power output end of the limiting cylinder, and one side of the limiting side plate faces the transport plane 1. The two battery cells can be synchronously transported through the two conveying tracks. When the two battery cells are transported to the limiting device, the limiting device can clamp the battery cells and correct the offset battery cells during the clamping process to prevent the position of the battery cells from shifting during the transportation process, ensure that the battery cells are straight during gluing, and further ensure that the rubber strips can be aligned with the top and around of the battery cells.

[0068] Regarding this embodiment, when gluing rectangular battery cells, the lengths and widths of the existing rectangular battery cells are different. Therefore, two rubber strips with different length dimensions are required to align the two sides of the rectangular battery cells before gluing can be performed. It should be supplemented that two different lengths of strip films can be supplied by the two glue supply devices 3, and different-sized films can be supplied by the two glue supply devices 3 when gluing different battery cells. Different films can be supplied according to actual production requirements, improving the scope of application.

[0069] Embodiment 3. To automatically perform a strip gluing operation on a square battery cell and automatically perform a glue strip separation operation on a plurality of glue strips. When the glue strips are supplied, for convenient stacking and transportation, a plurality of glue strips need to be transported and supplied in a manner of being juxtaposed and spliced to form the same tape. Since multiple glue strips on the same tape are in a juxtaposed bonding state, that is, the sides of adjacent glue strips are adhered to each other; therefore, before performing the glue strip fitting operation on the square battery cell, it is necessary to perform a separation operation on the adjacent glue strips. In this embodiment: The glue strip separation mechanism 7 includes a connecting vertical plate 71 and a lifting cylinder 72. The top of the connecting vertical plate 71 is movably provided with a supporting top plate 73, and the bottom of the connecting vertical plate 71 is fixedly provided with a supporting bottom plate 74. The lifting cylinder 72 is arranged outside the connecting vertical plate 71. By connecting the power output end of the lifting cylinder 72 to the outside of the supporting top plate 73, therefore, the lifting height of the supporting top plate 73 can be controlled by the lifting cylinder 72, so that the supporting top plate 73 is located directly above the fixed top plate 62, and the supporting bottom plate 74 is located directly below the fixed top plate 62. Align one side of the supporting top plate 73 with one side of the supporting bottom plate 74. By slidably arranging moving groove plates 75 on both one side of the supporting top plate 73 and one side of the supporting bottom plate 74, and by arranging pushing mechanisms 76 on both the outside of the supporting top plate 73 and the outside of the supporting bottom plate 74, connect the power output ends of the two pushing mechanisms 76 to the outside of the two moving groove plates 75 respectively. The two pushing mechanisms 76 are used to control the sliding distances of the two moving groove plates 75 respectively. A plurality of cam chutes 77 are opened on both moving groove plates 75, and the plurality of cam chutes 77 are arranged obliquely on the moving groove plates 75 in sequence. Also, align one side of the two moving groove plates 75. By opening a plurality of strip-shaped through grooves 621 on the surface of the fixed top plate 62, slidably arrange a plurality of strip-shaped glue strip separating plate members 78 on one side of the two moving groove plates 75, and stagger the plurality of strip-shaped glue strip separating plate members 78 with the plurality of strip-shaped through grooves 621 one by one. By arranging camshaft members 79 at the bottoms of the plurality of strip-shaped glue strip separating plate members 78, the plurality of camshaft members 79 are matched with the plurality of cam chutes 77 one by one;

[0070] When it is necessary to perform the glue separation action on the film on the fixed top plate 62, the driving mechanism 611 drives the glue separation mechanism 7 to move towards the glue discharging suction hole. When the supporting top plate 73 is directly above the glue discharging suction hole and the supporting bottom plate 74 is directly below the glue discharging suction hole, several strip-shaped glue separation plate members 78 are aligned with the glue strips one by one. At this time, the lifting cylinder 72 drives the supporting top plate 73 to move towards the supporting bottom plate 74, and one side of the supporting top plate 73 will slowly approach one side of the supporting bottom plate 74, so that several strip-shaped glue separation plate members 78 on the two moving groove plates 75 can clamp the glue strips. The power output ends of the two jacking mechanisms 76 can be respectively used to drive the two moving groove plates 75 to slide. During the sliding process of the moving groove plates 75, several cam chutes 77 will drive several strip-shaped glue separation plate members 78 to move. Since several cam chutes 77 are sequentially inclined on the moving groove plates 75, the strip-shaped glue separation plate members 78 will be driven to expand, realizing the glue separation action on the glue strips on the same film.

[0071] It should be noted that in order to ensure that the strip-shaped glue separation plate members 78 on the two moving groove plates 75 can firmly clamp the upper and lower surfaces of several glue strips, strip-shaped clamping members can be added to the opposite sides of the strip-shaped glue separation plate members 78 on the two moving groove plates 75, so that the moving distance can be reduced when one side of the supporting top plate 73 approaches one side of the supporting bottom plate 74, and thus the two sides of the glue strips can be clamped by the strip-shaped glue separation plate members 78 on the two moving groove plates 75.

[0072] Embodiment 4. To automatically remove the release paper on both sides of the tape, since there is generally release paper on both sides of the tape, the release paper is also called silicone oil paper and anti-sticking paper, which mainly serves to isolate sticky objects, such as tapes, and generally needs to be peeled off during use. Therefore, before the gluing operation, the release paper on both the upper and lower sides of the film needs to be removed to facilitate the subsequent gluing operation. In this embodiment: A clamping and flipping device 8 is provided between the glue supply device 3 and the glue taking device 4. The clamping and flipping device 8 includes a rotating mechanism 81 and two mounting plate members 82. Clamping mechanisms 83 are rotatably provided on one side of each of the two mounting plate members 82 so that the clamping openings of the two clamping mechanisms 83 are aligned. A clamping plate group 84 is also provided between the two clamping mechanisms 83, and both ends of the clamping plate group 84 are connected to the clamping fingers of the two clamping mechanisms 83 one by one, so that the rotating mechanism 81 is in driving connection with the two clamping mechanisms 83. Therefore, the rotating mechanism 81 can be used to synchronously control the rotation directions of the two clamping mechanisms 83. When removing the release paper on the bottom surface of the film, the glue taking device 4 can move the film close to the clamping and flipping device 8 so that the outside of the release paper on the bottom surface of the film is between the clamping plate group 84. The clamping mechanism 83 can drive the clamping plate group 84 to clamp the outside of the bottom release paper. The rotating mechanism 81 drives the clamping mechanism 83 to rotate, causing the release paper on the clamping mechanism 83 to bend downward, so that when the glue taking device 4 moves again, the release paper is separated from the bottom surface of the film, completing the removal of the release paper on the bottom surface of the film. After the removal is completed, the clamping mechanism 83 drives the clamping plate group 84 to loosen, facilitating the dropping of the release paper.

[0073] A jacking mechanism 421 is further provided at the top of the glue taking suction plate 42. The jacking mechanism 421 is inclinedly arranged at the top of the glue taking suction plate 42. A paper tearing clamp block 422 is provided at the power output end of the jacking mechanism 421, and one side of the paper tearing clamp block 422 is adjacent to the outside of the glue taking suction plate 42. After the removal of the release paper on the bottom surface of the film, when the release paper on the top surface of the film needs to be removed, the jacking mechanism 421 can drive the paper tearing clamp block 422 to retract at this time. A clamping opening is formed between one side of the paper tearing clamp block 422 and the outside of the glue taking suction plate 42. When the paper tearing clamp block 422 retracts, it can clamp the outside of the release paper on the top surface of the film on the glue taking suction plate 42. The moving mechanism 41 can drive the glue taking suction plate 42 to be located above the glue discharging suction holes, and the adsorption through holes of the glue discharging suction holes adsorb the bottom surface of the film that has been removed. At this time, when the moving mechanism 41 drives the glue taking suction plate 42 to move, during this moving process, when the glue taking suction plate 42 cancels the adsorption state of the release paper on the top surface of the film, the removal of the release paper on the top surface of the film can be realized when the glue taking suction plate 42 moves.

[0074] It should be noted that the clamping plate group 84 includes two strip-shaped clamping plates. One side of the two strip-shaped clamping plates is flush. The two ends of one strip-shaped clamping plate are respectively connected to the upper clamping fingers of the two clamping mechanisms 83, and the two ends of the other strip-shaped clamping plate are respectively connected to the lower clamping fingers of the two clamping mechanisms 83. Clamping paper plates are arranged outside the two strip-shaped clamping plates, and the clamping paper plates of the two strip-shaped clamping plates are aligned. When the upper and lower clamping fingers of the two clamping mechanisms 83 are combined, the two strip-shaped clamping plates are driven to be combined. At this time, the clamping paper plates of the two strip-shaped clamping plates are in a combined state, that is, the clamping paper plates of the two strip-shaped clamping plates form a clamping opening for clamping the release paper. The moving mechanism 41 of the glue taking device 4 can drive the glue taking suction plate 42 to approach the clamping opening, and the lifting strut can drive the glue taking suction plate 42 to correspond to the clamping opening, so that the clamping opening is aligned with the outside of the release paper on the bottom surface of the glue strip. The outside of the release paper on the bottom surface of the glue strip is clamped by the clamping paper plate; at this time, the rotating mechanism 81 can drive the two clamping mechanisms 83 to rotate synchronously in the same direction, so that the release paper is separated from the film, achieving the effect of automatically peeling the release paper on the film.

[0075] It should be noted that in order to detect whether the release paper at the bottom of the glue strip has been completely torn off, a glue application detection camera 21 is also arranged directly above the placement flat plate 2. The glue application detection camera 21 is located between the two glue feeding devices 6. When the glue taking device 4 is directly above the glue application detection camera 21, the camera of the glue application detection camera 21 faces directly below the glue taking suction plate 42. After tearing off the release paper on the bottom surface of the film, the glue taking device 4 can drive the film with the release paper on the bottom surface removed to be directly above the glue application detection camera 21 again. Whether the release paper on the bottom surface of the film is completely removed is detected by the camera of the glue application detection camera 21, effectively ensuring the production quality and preventing the situation that the cell glue application effect is affected because the release paper is not completely removed.

[0076] It should be noted that in order to centrally recycle the peeled release paper to prevent the release paper from scattering and affecting the processing environment, a recycling trough 9 is arranged directly below the glue taking device 4, and the notch of the recycling trough 9 faces the glue taking suction plate 42. Therefore, during the process of the glue taking device 4 tearing off the release paper, the release paper falls on the recycling trough 9, which is convenient for recycling the release paper on both sides of the film and preventing the release paper from scattering on the glue application station.

[0077] Embodiment 5. To apply strip adhesive tape to square battery cells of different sizes, the distance between two strip adhesive tape suction plates 520 needs to be adjusted to be applicable to square battery cells of different sizes for strip adhesive tape application, and it is also ensured that the two adhesive tapes during the adhesive tape application process can be respectively aligned with the two sides of the square battery to ensure that the edge position of the adhesive tape can be flush with the side of the battery cell during adhesive tape application, preventing the situation of adhesive tape exposure. Therefore, during the adhesive tape application process, the two adhesive tapes need to be respectively aligned with the two sides of the battery cell. In this embodiment: The glue taking device 4 includes a moving mechanism 41 and a glue taking suction plate 42. The moving mechanism 41 includes a robotic arm 411 and a lifting column 412. The lifting column 412 is movably arranged on the cross arm of the robotic arm 411, and one side of the glue taking suction plate 42 is arranged directly below the lifting column 412. The moving range of the glue taking suction plate 42 can be controlled by the moving mechanism 41, and the glue taking suction plate 42 can be moved to the glue supply device 3 for automatic glue taking operation. The adhesive tape application device 5 includes a displacement mechanism 51 and a connecting flat plate 52. One side of the connecting flat plate 52 is arranged on the power output end of the displacement mechanism 51, and the moving range of the connecting flat plate 52 is also controlled by the displacement mechanism 51. At least two strip adhesive tape suction plates 520 are slidably arranged on one side of the connecting flat plate 52. A number of adsorption through holes are arranged at the bottoms of the glue taking suction plate 42 and the two strip adhesive tape suction plates 520.

[0078] The displacement mechanism 51 and the moving mechanism 41 have the same structure. At least two pushing cylinders 521 are arranged on the other side of the connecting flat plate 52. The power output ends of the two pushing cylinders 521 are respectively connected to the tops of the two strip adhesive tape suction plates 520. The sliding distance of the strip adhesive tape suction plates 520 can be controlled by the pushing cylinders 521. Therefore, the two strip adhesive tape suction plates 520 can be driven by the two pushing mechanisms to slide on the connecting flat plate 52, and thus the distance between the two strip adhesive tape suction plates 520 can be adjusted to align the two strip adhesive tape suction plates 520 with the two sides of the top of the square battery cell respectively, realizing the adhesive tape application operation applicable to square battery cells of different sizes.
