Description

Glue sticking device, glue sticking method and battery processing equipment Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a gluing device, a gluing method and battery processing equipment. Background Art

[0002] During the battery processing process, the battery cells need to be glued and then two or more battery cells are glued and fixed together using adhesive tape so that multiple battery cells can be stacked along the thickness direction of the battery cells and then assembled into a battery module or directly assembled into a battery.

[0003] However, the current gluing process usually adopts a mechanical positioning method, which results in low gluing accuracy of the adhesive tape on the battery cell, affecting the assembly accuracy of the battery cell and thus affecting the structural accuracy of the final assembled battery module or battery.

[0004] Summary of the Invention

[0005] Based on this, the present application provides a gluing device, a gluing method and a battery processing equipment.

[0006] In a first aspect, the present application provides a glue applying device, comprising:

[0007] A workbench, comprising a first accommodation position for placing a battery cell;

[0008] A gluing mechanism, used to stick the adhesive tape onto the battery cell;

[0009] A detection component is provided on the workbench and is used to detect the current position of the battery cell in the first accommodation position and the current position of the adhesive tape on the adhesive application mechanism; and

[0010] The visual compensation module is respectively connected to the gluing mechanism and the detection component for communication. The visual compensation module is configured to obtain a total deviation value based on the deviation values ​​between the current positions of the battery cells and the adhesive tape and the target positions, so as to correct the gluing position of the gluing mechanism.

[0011] In the technical solution of the embodiment of the present application, the detection component can respectively detect the current position of the battery cell and the adhesive tape. The visual compensation module can obtain a total deviation value based on the deviation between the current position of the battery cell and the adhesive tape and the target position. The gluing mechanism is then corrected based on the total deviation value, so that the gluing mechanism can apply glue to the battery cell at the corrected gluing position. Through practice, it has been found that the gluing accuracy of traditional gluing methods is usually less than or equal to 1.5mm. After correction through the above-mentioned visual compensation method, the gluing accuracy can be improved to less than or equal to 0.8mm, thereby effectively improving the gluing accuracy of the battery cell.

[0012] In some embodiments, the detection assembly includes a first detection member and a second detection member, each of which is communicatively connected to the vision compensation module, the first detection member being used to detect a first current position of the battery cell in the first accommodation position, and the second detection member being used to detect a second current position of the adhesive tape on the adhesive application mechanism; and the target position of the battery cell in the first accommodation position is defined as the first target position, and the target position of the adhesive tape on the adhesive application mechanism is defined as the second target position;

[0013] Among them, the visual compensation module is used to compare the first current position with the first target position to obtain a first deviation value, and is also used to compare the second current position with the second target position to obtain a second deviation value, and obtain a total deviation value based on the first deviation value and the second deviation value.

[0014] In the technical solution of the embodiment of this application, the first and second detection components detect and locate the battery cells and the adhesive tape, respectively, thereby quickly determining their respective current positions. The visual compensation module then compares these positions to quickly and accurately determine the total deviation between the battery cells and the adhesive tape. This total deviation allows for precise visual compensation during the adhesive application process, effectively improving adhesive application accuracy.

[0021] In some embodiments, the glue applying mechanism further includes an adjusting member connected between the moving member and the glue taking member, and the adjusting member is used to adjust the distance between the glue taking member and the moving member.

[0066] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in other fields. As the application of power batteries continues to expand, market demand is also growing.

[0067] A battery cell is the smallest unit that makes up a battery. Specifically, multiple battery cells can be connected in series, parallel, or in a hybrid configuration to form a battery module. One or more battery modules are then connected and assembled to form a battery. Of course, multiple battery cells can also be directly assembled to form a battery. Hybrid configuration refers to multiple battery cells connected both in series and in parallel.

[0068] In the process of assembling a battery module or battery from battery cells, it is usually necessary to apply glue to the surface of the battery cells, then stack multiple battery cells in the thickness direction and glue and fix them using adhesive tape on the surfaces of adjacent battery cells.

[0069] During the above process, the glue lamination accuracy will affect the assembly accuracy of the battery cells and even the structural accuracy of the final assembled battery module or battery.

[0070] Currently, mechanical positioning is commonly used when gluing battery cells. However, due to machining errors, it is impossible to ensure positional consistency across the gluing process, ultimately limiting gluing accuracy and preventing improvements.

[0071] Based on the above considerations, in order to solve the problem of low gluing accuracy in the current battery cell gluing process, one or more embodiments of the present application provide a gluing device, which positions the battery cell and the adhesive tape on a workbench and a gluing mechanism respectively. The current positions of the battery cell and the adhesive tape are detected by a detection component. The visual compensation module can obtain a total deviation value based on the deviation values ​​between the current positions of the battery cell and the adhesive tape and the target positions, and then correct the gluing position of the gluing mechanism based on the total deviation value, ultimately enabling the gluing mechanism to glue the battery cell at the corrected gluing position. In this way, mechanical errors between the adhesive tape and the battery cell or errors caused by other external factors can be compensated by visual compensation, thereby achieving higher gluing accuracy.

[0072] Please refer to Figure 1. According to one or more embodiments, a gluing device 100 is provided, including a workbench 10, a gluing mechanism 20, a detection component 30 and a visual compensation module (not shown in the figure). Among them, a first receiving position 11 for placing a battery cell is provided on the workbench 10. The gluing mechanism 20 is used to stick the adhesive tape to the battery cell. The detection component 30 is arranged on the workbench 10, and is used to detect the current position of the battery cell in the first receiving position 11 and the current position of the adhesive tape on the gluing mechanism 20. The visual compensation module is respectively communicated with the gluing mechanism 20 and the detection component 30, and the visual compensation module is configured to obtain a total deviation value based on the deviation value between the current position of the battery cell and the adhesive tape and the target position, so as to correct the gluing position of the gluing mechanism 20.

[0073] It should be noted that the workbench 10 refers to a structure that can provide a load-bearing and support base for the battery cells so as to facilitate gluing the battery cells. The first accommodating position 11 refers to a position that can be used to place the battery cells and perform the gluing operation on the battery cells. Among them, the first accommodating position 11 can be set as one, or can be set as multiple spaced apart from each other. When multiple first accommodating positions 11 are provided, a battery cell can be placed on each first accommodating position 11, and then the battery cells on different first accommodating positions 11 can be glued separately to improve the gluing efficiency.

[0074] The target position of the battery cell in the first accommodation position 11 refers to the theoretical preset adhesive bonding position of the battery cell. However, in actual operation, due to machining errors or other external factors, the actual position of the battery cell in the first accommodation position 11 may differ from the target position. In this case, the actual position is the current position of the battery cell in the first accommodation position 11.

[0075] Similarly, the target position of the tape on the gluing mechanism 20 refers to the theoretically predetermined position of the tape on the gluing mechanism 20. However, in actual operation, due to machining errors or other external factors, the actual position of the tape on the gluing mechanism 20 may differ from the target position. In this case, the actual position is the current position of the tape on the gluing mechanism 20.

[0076] There is a certain deviation between the current position of the battery cell in the first accommodation position 11 and its target position. There is also a certain deviation between the current position of the adhesive tape on the adhesive laminating mechanism 20 and its target position. The sum of the two deviations is the total deviation between the battery cell and the adhesive tape.

[0077] The visual compensation module compares the current position of the battery cell with its target position, and the current position of the adhesive tape with its target position, respectively, to obtain deviation values ​​for the battery cell and the adhesive tape, respectively. The same visual compensation module can be used to sequentially compare the current position of the battery cell with its target position, and the current position of the adhesive tape with its target position, or two or more visual compensation modules can be used to simultaneously compare the battery cell and the adhesive tape.

[0078] Furthermore, the deviation values ​​of the two are integrated through the internal algorithm of the visual compensation module to obtain a total deviation value. Specifically, when the deviation value of the battery cell is in the same direction as the deviation value of the adhesive tape, the visual compensation module subtracts the numerical values ​​of the two deviation values ​​to obtain a total deviation value. When the deviation value of the battery cell is in the opposite direction to the deviation value of the adhesive tape, the visual compensation module adds the numerical values ​​of the two deviation values ​​to obtain a total deviation value. The visual compensation module controls the movement of the gluing mechanism 20 according to the total deviation value, so that the amount moved by the gluing mechanism 20 can compensate for the total deviation value, thereby correcting the gluing position of the gluing mechanism 20. Finally, the gluing mechanism 20 is controlled to perform gluing at the gluing position. In this way, the gluing accuracy can be effectively improved.

[0079] Through the above structure, the detection component 30 can respectively detect the current position of the battery cell and the adhesive tape. The visual compensation module can obtain a total deviation value based on the deviation between the current position of the battery cell and the adhesive tape and the target position. Then, the gluing mechanism 20 is corrected based on the total deviation value, so that the gluing mechanism 20 can glue the battery cell at the corrected gluing position. The present application uses the above-mentioned visual compensation method to perform correction, which can effectively improve the gluing accuracy of the battery cell.

[0080] As shown in Figures 1 and 2, in some embodiments, the detection component 30 includes a first detection member 31 and a second detection member 32, each of which is communicatively connected to the visual compensation module. The first detection member 31 is used to detect the first current position of the battery cell in the first accommodation position 11, and the second detection member 32 is used to detect the second current position of the adhesive tape on the gluing mechanism 20. The target position of the battery cell in the first accommodation position 11 is defined as the first target position, and the target position of the adhesive tape on the gluing mechanism 20 is defined as the second target position. The visual compensation module is used to compare the first current position with the first target position to obtain a first deviation value, and is also used to compare the second current position with the second target position to obtain a second deviation value, and to obtain a total deviation value based on the first deviation value and the second deviation value.

[0081] Specifically, the first detection member 31 can be, but is not limited to, configured as a first positioning camera. When a battery cell is placed in the first accommodation position 11, the first detection member 31 takes a picture of the battery cell on the first accommodation position 11, thereby obtaining a first current position of the battery cell on the first accommodation position 11. The visual compensation module obtains the first current position and compares the first current position with a preset first target position to obtain a first deviation value, which is the offset of the battery cell on the first accommodation position 11.

[0082] The second detection member 32 can be, but is not limited to, configured as a second positioning camera. When the tape is fixed to the gluing mechanism 20, the second detection member 32 takes a picture of the tape on the gluing mechanism 20, thereby obtaining a second current position of the tape on the gluing mechanism 20. The visual compensation module obtains the second current position and compares it with a preset second target position to obtain a second deviation value, which is the offset of the tape on the gluing mechanism 20.

[0083] The visual compensation module uses its internal algorithm to combine the first and second deviation values ​​to determine a total deviation value, representing the total offset between the battery cell and the adhesive tape. Specifically, when the first and second deviation values ​​are offset in the same direction, the visual compensation module subtracts the first and second deviation values ​​to determine the total deviation value. When the first and second deviation values ​​are offset in opposite directions, the visual compensation module adds the first and second deviation values ​​to determine the total deviation value.

[0084] The visual compensation module controls the gluing mechanism 20 to move the adhesive tape based on the total deviation value, thereby correcting the gluing position of the gluing mechanism 20 and visually compensating for the total deviation value. Finally, the visual compensation module controls the gluing mechanism 20 to apply adhesive at the corrected gluing position to achieve higher gluing accuracy.

[0085] The first detection member 31 and the second detection member 32 respectively detect and locate the battery cell and the adhesive tape, thereby quickly determining their respective current positions. The visual compensation module then compares these positions to quickly and accurately determine the total deviation between the battery cell and the adhesive tape. This total deviation allows for precise visual compensation during the adhesive application process, effectively improving adhesive application accuracy.

[0086] In some embodiments, the gluing device 100 also includes a positioning platform 40 and a positioning member (not shown in the figure) arranged on the workbench 10. The positioning platform 40 has a second receiving position 41 for receiving the adhesive tape, and the positioning member is used to initially position the adhesive tape in the second receiving position 41.

[0087] Specifically, the adhesive tape is first placed on the positioning platform 40 and initially positioned at the second receiving position 41 on the positioning platform 40 using the positioning member. The adhesive tape is then removed from the second receiving position 41 by the adhesive application mechanism 20, and the second detection member 32 detects the second current position of the adhesive tape on the adhesive application mechanism 20. The visual compensation module then compares the second current position with a preset second target position to obtain a second deviation value for the adhesive tape.

[0088] By initially positioning the adhesive tape in the second accommodation position 41 through the positioning member, the second deviation value formed by the adhesive tape on the adhesive laminating mechanism 20 can be reduced, thereby narrowing the range of visual compensation.

[0089] Furthermore, the positioning platform 40 may be, but is not limited to, a positioning plate with a positioning opening formed therethrough. The positioning member may be, but is not limited to, a third positioning camera disposed below the positioning platform 40 and opposite to the positioning opening.

[0090] When the adhesive tape is placed on the positioning platform 40, the positioning member takes a picture of the adhesive tape from bottom to top through the positioning port to obtain the actual position of the adhesive tape on the positioning platform 40, and then moves the adhesive tape to position it in the second receiving position 41 to complete the initial positioning of the adhesive tape.

[0091] It is understandable that other methods can also be used to achieve the positioning of the adhesive tape in the second accommodating position 41, for example, setting the positioning member as a limiting member on the positioning platform 40, and forming the second accommodating position 41 by enclosing the positioning member, and achieving the initial positioning of the adhesive tape in the second accommodating position 41 through the limiting effect of the positioning member.

[0092] The positioning platform 40 and the positioning member are used to realize the initial positioning of the adhesive tape in the second receiving position 41, so that after the gluing mechanism 20 takes the adhesive tape from the second receiving position 41, the position of the adhesive tape on the gluing mechanism 20 is more accurate, and the second deviation value between the second current position and the second target position of the adhesive tape on the gluing mechanism 20 is reduced, which is more conducive to further high-precision positioning and gluing between the battery cell and the adhesive tape through visual compensation.

[0093] Referring to Figures 1, 2, and 3, in some embodiments, the adhesive tape applying mechanism 20 is movably disposed between the second receiving position 41 and the first receiving position 11. The adhesive tape applying mechanism 20 is configured to remove adhesive tape from the second receiving position 41 and apply the adhesive tape to the battery cell. Thus, the adhesive tape can be smoothly moved from the second receiving position 41 to the first receiving position 11 for adhesive application.

[0094] In some embodiments, the adhesive application mechanism 20 includes a movable member 21 and an adhesive dispensing member 22 disposed on the movable member 21. The adhesive dispensing member 22 is used to remove or release adhesive tape. The movable member 21 is movably disposed on the workbench 10 and is used to drive the adhesive dispensing member 22 to move between the second receiving position 41 and the first receiving position 11.

[0095] Specifically, the moving member 21 can be, but is not limited to, a robot arm, which drives the adhesive taking member 22 to move, thereby taking and releasing the adhesive tape.

[0096] The adhesive removal part 22 can be, but is not limited to, set as a suction cup, which can absorb or release the adhesive tape. First, the manipulator drives the suction cup to move to just above the second accommodating position 41, and the suction cup absorbs the adhesive tape on the second accommodating position 41, and then detects the second current position of the adhesive tape on the suction cup through the second detection part 32. The manipulator drives the suction cup and the adhesive tape from the second accommodating position 41 to just above the first accommodating position 11. At the same time, the visual compensation module obtains the second current position and obtains the second deviation value, and combines the first deviation value of the battery cell to obtain the total deviation value. At this time, the visual compensation module controls the movement of the gluing mechanism 20 according to the total deviation value, corrects the gluing position of the gluing mechanism 20, and finally enables the gluing mechanism 20 to attach the adhesive tape to the large surface of the battery cell at the gluing position, thereby achieving high-precision gluing.

[0097] It should be noted that when battery cells are stacked, they are typically stacked along their thickness, so that the large surfaces of adjacent battery cells are aligned. Therefore, adhesive tape is applied to the large surfaces of the battery cells to achieve adhesion and fixation between the battery cells. The large surface is the largest surface on the battery cell.

[0098] Furthermore, in order to make the suction cup absorb the adhesive tape more stably, a plurality of suction cups spaced apart from each other can be provided, thereby increasing the adsorption area of ​​the suction cup on the adhesive tape and making the force on the adhesive tape more uniform.

[0099] By providing the moving member 21, the adhesive taking member 22 and the adhesive tape thereon can be smoothly driven to move between the second accommodation position 41 and the first accommodation position 11. The adhesive taking member 22 can smoothly take and release the adhesive tape, and finally achieve smooth adhesive application.

[0100] In some embodiments, the glue applying mechanism 20 further includes an adjusting member 23 connected between the moving member 21 and the glue taking member 22 . The adjusting member 23 is used to adjust the distance between the glue taking member 22 and the moving member 21 .

[0101] It should be noted that during the gluing process, the battery cells to be glued may have different specifications, and the thickness, height, and width of the battery cells of different specifications may vary. When the thickness of the battery cells of different specifications varies, when the battery cells are placed in the first receiving position 11, the large surface of the battery cells to be glued faces upward, and the heights of the battery cells also vary.

[0102] Based on this, an adjustment member 23 is provided between the movable member 21 and the adhesive dispensing member 22. When the movable member 21 drives the adhesive dispensing member 22 to move directly above the first accommodation position 11, the movable member 21 drives the adhesive dispensing member 22 and the adhesive tape thereon downward a certain distance, so that the adhesive dispensing member 22 can adhere the adhesive tape to the large surface of the battery cell.

[0103] At this time, the distance between the adhesive removing member 22 and the moving member 21 can be adjusted by the adjusting member 23, so that the adhesive removing member 22 can be more smoothly adapted to battery cells of different thicknesses, thereby smoothly and stably attaching the adhesive tape to the large surface of the battery cell.

[0104] Specifically, the adjusting member 23 can be, but is not limited to, a telescopic cylinder, which can move the adhesive removing member 22 closer to or away from the moving member 21 through its telescopic movement, so that the adhesive removing member 22 can better adhere the adhesive tape to the large surface of the battery cell.

[0105] In some embodiments, a bolt connection can be provided between the movable member 21 and the glue extracting member 22, and the distance between the glue extracting member 22 and the movable member 21 can be adjusted by rotating the bolt, or other connection methods can be used to achieve the purpose of adjusting the distance between the glue extracting member 22 and the movable member 21, which will not be elaborated here.

[0106] By setting the adjusting member 23, the distance between the adhesive removing member 22 and the moving member 21 can be flexibly adjusted according to the different specifications of the battery cells to be glued during gluing, so that the adhesive removing member 22 can more smoothly and stably attach the adhesive tape to the battery cells, thereby improving the gluing stability.

[0107] In some embodiments, the gluing device 100 also includes a material bin 50 and a loading mechanism 60. The material bin 50 is arranged on at least one side of the workbench 10. The loading mechanism 60 is arranged between the material bin 50 and the workbench 10 and is used to move the adhesive tape in the material bin 50 to the workbench 10.

[0108] Specifically, the hopper 50 is disposed on one side of the workbench 10 , so that the loading mechanism 60 can take the adhesive tape from the hopper 50 , and then place the adhesive tape on the positioning platform 40 , and initially position the adhesive tape on the second receiving position 41 .

[0109] Furthermore, the feeding mechanism 60 can be, but is not limited to, a feeding robot, and a suction cup is provided on it to take and release the adhesive tape.

[0110] The loading robot moves the suction cup to the top of the hopper 50, where it descends and picks up the adhesive tape from the hopper 50. The loading robot then moves the suction cup from the hopper 50 to the positioning platform 40, positioning the adhesive tape in the second receiving position 41 on the positioning platform 40. This completes the initial positioning of the adhesive tape.

[0111] Next, the moving member 21 of the gluing mechanism 20 moves the suction cup thereon to directly above the second receiving position 41 and picks up the adhesive tape. The second detection member 32 detects the second current position of the adhesive tape on the suction cup. The visual compensation module then determines a second deviation value for the adhesive tape based on the second current position and the second target position. The visual compensation module combines the first and second deviation values ​​to ultimately determine a total deviation value. The gluing position of the gluing mechanism 20 is corrected, enabling the gluing mechanism 20 to perform high-precision gluing of the battery cells at the gluing position.

[0112] By providing the material bin 50 and the feeding mechanism 60, the adhesive tape can be fed and smoothly moved to the workbench 10 for the adhesive application operation, thereby improving the adhesive application efficiency.

[0113] In some embodiments, the adhesive application mechanism 20 further includes a peeling member 24 for removing the release paper from the adhesive tape. The peeling member 24 can be disposed on the workbench 10, or on the adhesive application mechanism 20, or on both the workbench 10 and the adhesive application mechanism 20.

[0114] Specifically, since release paper is provided on both sides of the adhesive tape in the initial state, there are two adhesive peeling operations during the entire adhesive application process.

[0115] First, the loading mechanism 60 removes the adhesive tape from the hopper 50 and moves it to the adhesive peeling member 24. The adhesive peeling member 24 then removes the release paper from the bottom surface of the adhesive tape, and the adhesive tape is then placed in the second receiving position 41. Furthermore, the moving member 21 drives the adhesive removal member 22 to remove the adhesive tape from the second receiving position 41, and then moves it to the adhesive application position to facilitate application of the adhesive tape to the battery cell.

[0116] After the adhesive tape is attached to the large surface of the battery cell, the release paper on the side of the adhesive tape facing away from the battery cell is removed using the adhesive peeling member 24. Thus, when the battery cells are stacked, the adhesive tape on the side facing away from the battery cell can adhere to the large surface of adjacent battery cells, thereby achieving adhesion and fixation between the battery cells.

[0117] Therefore, in the above process, one or more adhesive tearing pieces 24 can be provided according to actual needs, and the adhesive tearing pieces 24 can be provided at appropriate positions to facilitate the smooth removal of the release paper on the adhesive tape.

[0118] For example, a first tear-off member 24 can be provided around the positioning platform 40. After the loading mechanism 60 removes the adhesive tape from the hopper 50, the release paper on the bottom surface of the adhesive tape can be removed using the first tear-off member 24 before the adhesive tape is placed on the positioning platform 40. Furthermore, a second tear-off member 24 can be provided on the adhesive application mechanism 20. Thus, after the adhesive tape is applied to the large surface of the battery cell, the release paper on the side of the adhesive tape facing away from the battery cell can be removed using the second tear-off member 24 on the adhesive application mechanism 20.

[0119] Therefore, by providing the adhesive peeling piece 24 , the adhesive tape can be smoothly attached to the battery cell.

[0120] In some embodiments, the detection assembly 30 further includes a third detection member 33 disposed on the workbench 10 , and the third detection member 33 is used to detect the state of the release paper on the adhesive tape.

[0121] Specifically, the third detection member 33 can be, but is not limited to, configured as a positioning camera. Furthermore, the third detection member 33 and the second detection member 32 can share the same positioning camera, meaning the third detection member 33 can also be configured as a second positioning camera. After the release paper on the adhesive tape is removed by the adhesive removal member 24, the third detection member 33 can be used to take a photo of the adhesive tape to verify that the release paper has been removed cleanly, thereby ensuring that the adhesive tape is more securely attached to the battery cell.

[0122] Based on the same concept as the above-mentioned gluing device 100, the present application also provides a battery processing equipment, including the above-mentioned gluing device 100, which is used to stick adhesive tape to the large surface of the battery cell.

[0123] As shown in FIG4 , based on the same concept as the above-mentioned gluing device 100 , the present application also provides a gluing method, comprising the following steps:

[0124] S20 : ​​Detecting and obtaining the current position of the battery cell at the first accommodation position 11 on the workbench 10 .

[0125] S30: Detect and obtain the current position of the adhesive tape on the adhesive laminating mechanism 20.

[0126] S40 : Obtaining a total deviation value according to the deviation values ​​between the current positions of the battery cells and the adhesive tape and the target positions, so as to calibrate the adhesive position of the adhesive bonding mechanism 20 .

[0127] The target position is the theoretically set position of the battery cell and the adhesive tape. However, in actual operation, the actual position of the battery cell and the adhesive tape often deviates from the target position. Therefore, the visual compensation module compares the current position of the battery cell with its target position, and the current position of the adhesive tape with its target position, thereby obtaining a total deviation value. The adhesive application position of the adhesive application mechanism 20 is corrected based on this total deviation value.

[0128] S50: Controlling the gluing mechanism 20 to glue the battery cell at the gluing position. The visual compensation module controls the gluing mechanism 20 to move the adhesive tape thereon to the gluing position according to the total deviation value, and then controls the gluing mechanism 20 to glue the battery cell at the gluing position.

[0129] The visual compensation module corrects the gluing position of the gluing mechanism 20 according to the total deviation value, so that the gluing mechanism 20 can glue the battery cells more accurately, thereby achieving high-precision gluing.

[0130] In some embodiments, the step S40 of obtaining a total deviation value based on the deviation values ​​between the current positions of the battery cells and the adhesive tape and the target positions to correct the adhesive application position of the adhesive application mechanism 20 further includes the following steps:

[0131] S41: Preset a first target position and a second target position, wherein the first target position is the target position of the battery cell in the first accommodation position 11, and the second target position is the target position of the adhesive tape on the adhesive laminating mechanism 20. The first target position and the second target position are preset in the visual compensation module.

[0132] S42: Compare the first current position with the first target position to obtain a first deviation value.

[0133] S43: Compare the second current position with the second target position to obtain a second deviation value.

[0134] S44: Obtain a total deviation value according to the first deviation value and the second deviation value.

[0135] The visual compensation module compares the first current position with the first target position and obtains a first deviation value. Simultaneously, the second current position is compared with the second target position and obtains a second deviation value. Combining the first and second deviation values ​​yields a total deviation value. Based on the total deviation value, the adhesive application mechanism 20 is controlled to perform visual compensation, thereby correcting the adhesive application position of the adhesive application mechanism 20 and achieving high-precision adhesive application.

[0136] In some embodiments, before the step S30 in which the detection component 30 detects and obtains the current position of the adhesive tape on the adhesive laminating mechanism 20, the following steps are further included:

[0137] S14: Initially positioning the adhesive tape at the second accommodation position 41 on the positioning platform 40. Before performing visual compensation by the visual compensation module, the adhesive tape is initially positioned at the second accommodation position 41 to reduce the second deviation value of the adhesive tape on the gluing mechanism 20.

[0138] S15: Controlling the gluing mechanism 20 to remove the adhesive tape from the second receiving position 41. After the adhesive tape is initially positioned in the second receiving position 41, the gluing mechanism 20 is controlled to remove the adhesive tape from the second receiving position 41. The second current position of the adhesive tape is then detected, and a second deviation value is obtained to further improve the gluing accuracy.

[0139] In some embodiments, before step S14 of initially positioning the adhesive tape at the second receiving position 41 on the positioning platform 40, the following steps are further included:

[0140] S11: Control the loading mechanism 60 to take the adhesive tape from the hopper 50 .

[0141] S12: Tear off the release paper on the side of the adhesive tape facing away from the feeding mechanism 60.

[0142] S13: Check whether the release paper on the adhesive tape is torn off completely.

[0143] In some embodiments, after step S40 of controlling the gluing mechanism 20 to glue the battery cells at the gluing position, the following steps are further included:

[0144] S60: Tear off the release paper on the side of the adhesive tape facing away from the battery cell.

[0145] Through the above steps, high-precision gluing of battery cells is completed, which makes the subsequent stacking of battery cells to form battery modules or batteries smoother and can improve the structural accuracy of the battery modules or batteries.

[0146] It should be noted that, although the steps in the flowchart of FIG4 are connected in sequence by arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders.
