[0035] Combination Figure 1 and Figure 2 As shown, the first aspect of this embodiment provides a glue sticking device 100, comprising: a placement platform 20 and a glue sticking assembly 10, wherein:

[0036] The placement platform 20 is provided with a first notch 21 and a second notch 22, and the first notch 21 and the second notch 22 are arranged along the length direction of the battery cell 1 (the first direction, i.e., the extension direction of the pole ear, Figure 5The placement platform 20 is arranged relatively to the x-axis direction in the figure, and is used to carry the battery cell 1, and the lower surface (i.e., the second surface) of the battery cell 1 is in contact with the placement platform 20;

[0037] The two glue sticking components 10 are respectively arranged on the opposite sides of the placement platform 20 along the length direction of the battery cell. The two glue sticking components 10 respectively stick glue to the two ends of the battery cell 1 along the length direction, one of the glue sticking components 10 sticks glue to the head of the battery cell 1, and the other glue sticking component 10 sticks glue to the tail of the battery cell 1; the two glue sticking components 10 have the same structure, each of the glue sticking components 10 includes a glue disc 11, and the glue disc 11 is adsorbed with insulating tape. The glue disc 11 can move along the length direction of the battery cell 1, and the glue disc 11 can be accommodated in the first notch 21 or the second notch 22. The insulating tape is attached to the lower surface of the battery cell 1, and the glue disc 11 can be moved along the thickness direction of the battery cell 1 (that is, the third direction, Figure 7 The insulating tape is moved in the z-axis direction of the battery cell 1 to attach the insulating tape to the upper surface of the battery cell 1 and between the upper surface and the lower surface of the battery cell 1.

[0038] The gluing device provided in the present embodiment sets a first notch and a second notch on the placement platform, so that the glue discs of the two glue-sticking components can move into the first notch or the second notch to glue the lower surface of the battery cell, and the glue disc can move along the length direction and thickness direction of the battery cell, and can glue the upper surface of the battery cell and between the upper surface and the lower surface, so that the insulating tape attached to the battery cell is U-shaped, which can provide more comprehensive protection for the battery cell and improve the safety of the battery cell, and the gluing device can glue both sides of the head and tail of the battery cell at the same time, thereby improving the gluing efficiency and the yield rate of gluing; in addition, by cooperating with the glue disc and the first notch and the second notch, the gluing device does not need to reverse the glue sticking or flip the glue sticking when gluing both sides of the battery cell, which is conducive to further improving the gluing efficiency, and the gluing device has a higher degree of integration, a more compact structure, and a higher gluing accuracy.

[0039] Based on the above embodiment, as an optional implementation mode, Figure 2 As shown, the placement platform 20 is fixedly set on the support frame 23, and the support frame 23 is used to support the placement platform 20. A groove 231 is opened at one end of the support frame 23 close to the placement platform 20, and the groove 231 is connected with the first notch 21. Therefore, by setting the groove 231, an avoidance space can be provided, which facilitates the movement of the rubber disc 11 along the length direction and thickness direction of the battery cell 1.

[0040] Based on the above embodiment, as an optional implementation mode, Figure 3 and Figure 4As shown, the adhesive disc 11 is provided with a plurality of adsorption holes 111, and the plurality of adsorption holes 111 can be evenly arranged on the upper surface of the adhesive disc 11. The adhesive disc 11 vacuum adsorbs the non-adhesive surface of the insulating tape through the adsorption holes 111, so as to attach the insulating tape to both sides and between both sides of the battery cell 1. The end of the adhesive disc 11 facing the battery cell 1 is connected by a rounded transition, that is, the two corners of the end of the adhesive disc 11 facing the battery cell are set as rounded corners. Therefore, when the adhesive disc 11 attaches the insulating tape to the upper surface and the upper and lower surfaces of the battery cell 1, it can be avoided that the corners of the adhesive disc 11 scratch or tear the insulating tape, which affects the yield rate of the adhesive attachment of the battery cell 1.

[0041] On the basis of the above embodiment, as an optional implementation, a fourth notch 113 is provided on one end of the rubber disc 11 facing the battery cell 1, and the fourth notch 113 extends along the first direction. The cutting end of the cutter 112 is accommodated in the fourth notch 113, and the non-cutting end of the cutter 112 is arranged away from the battery cell 1 and extends to the outside of the rubber disc 11. The cutter 112 can move along the length direction of the battery cell 1, so that the cutting end of the cutter 112 extends from the fourth notch 113 to cut the insulating tape. The non-cutting end of the cutter 112 can be connected to a cutter drive to drive the cutter 112 to move along the length direction of the battery cell 1, so that the cutting end of the cutter 112 extends from the fourth notch 113, or the cutting end of the cutter 112 is accommodated in the fourth notch 113. Therefore, by setting the cutter 112 inside the glue disc 11 and allowing the cutter 112 to move along the length direction of the battery cell 1, not only can the insulating tape be effectively cut, but the space inside the glue disc 11 can also be reasonably utilized, which is conducive to reducing the volume of the glue sticking device.

[0042] Based on the above embodiment, as an optional implementation, the glue assembly 10 further includes a first glue disc driver 12 and a second glue disc driver 13, wherein the first glue disc driver 12 is used to drive the glue disc 11 to move along the length direction of the battery cell 1, and the second glue disc driver 13 is used to drive the glue disc 11 to move along the thickness direction of the battery cell 1. Thus, the glue disc 11 can be moved along the length direction and the thickness direction of the battery cell 1.

[0043] Based on the above embodiment, as an optional implementation mode, Figure 5 and Figure 6 As shown, the adhesive laminating device 100 further includes a piezoelectric core assembly 30, and two piezoelectric core assemblies 30 are respectively arranged at two opposite ends of the placement platform 20 along the length direction of the battery core, and the two piezoelectric core assemblies 30 respectively abut against the two ends of the battery core 1 along the length direction, and the two piezoelectric core assemblies 30 are both along the width direction of the battery core (i.e., the second direction, i.e., Figure 7y-axis direction in the figure) is arranged on one side of the glue sticking component 10, wherein one piezoelectric core component 30 is used to hold the head of the battery cell 1, and the other piezoelectric core component 30 is used to hold the tail of the battery cell 1, and the two piezoelectric core components 30 have the same structure. Each piezoelectric core component 30 includes a pressing plate 31, which can move along the thickness direction of the battery cell and is used to hold the upper surface of the battery cell 1. A third notch 32 is provided on the pressing plate 31, and the third notch 32 and the first notch 21 are arranged opposite to each other, or the third notch 32 and the second notch 22 are arranged opposite to each other. The glue disc 11 can pass through the third notch 32 to stick the insulating tape on the upper surface of the battery cell 1. Therefore, by setting the piezoelectric core component 30, the position of the battery cell 1 can be fixed when the battery cell 1 is glued, so as to prevent the position of the battery cell 1 from shifting during the process of gluing, which affects the quality of gluing. By setting the third notch 32 on the pressing plate 31, the third notch 32 can provide an avoidance space, which is convenient for the glue disc 11 to glue the upper surface of the battery cell 1.

[0044] On the basis of the above embodiment, as an optional implementation, at least two third notches 32 are provided on the pressing plate 31 along the width direction of the battery cell, and a first preset distance is spaced between any two adjacent third notches 32. Thus, when applying insulating glue to the battery cell, the pressing plate 31 can simultaneously support at least two battery cells 1. By providing at least two third notches 32 on the pressing plate 31, the two third notches 32 can simultaneously provide an escape space, so that glue can be applied to multiple battery cells 1 at the same time, which is conducive to improving the efficiency of glue application.

[0045] It should be noted that, in this embodiment, the specific numerical range of the first preset distance is not further limited, and those skilled in the art may set it according to actual conditions.

[0046] Based on the above embodiment, as an optional implementation, each piezoelectric cell assembly 30 also includes a pressure plate driver 33, which is used to drive the pressure plate 31 to move along the thickness direction of the battery cell 1 so that the pressure plate 31 approaches the battery cell 1 or moves away from the battery cell 1.

[0047] Combination Figure 7As shown, the second aspect of the present embodiment provides a gluing production line, which includes a first gluing device 100a and a second gluing device 100b, and the first gluing device 100a and the second gluing device 100b are both the gluing devices 100 described in the first aspect. The first gluing device 100a and the second gluing device 100b are arranged at intervals along the width direction (i.e., the second direction) of the battery cell 1, the first gluing device 100a is used to apply the first insulating tape to both ends of the battery cell 1 along the length direction, and the second gluing device 100b is used to apply the second insulating tape to both ends of the battery cell 1 along the length direction, the first insulating tape and the second insulating tape are arranged along the width direction of the battery cell 1, the first insulating tape and the second insulating tape can be arranged at intervals along the width direction of the battery cell 1, that is, the spacing between the first insulating tape and the second insulating tape is greater than 0, and the first insulating tape and the second insulating tape can also be arranged in contact along the width direction of the battery cell 1, that is, the spacing between the first insulating tape and the second insulating tape is 0. Therefore, the gluing production line provided in this embodiment can glue wide battery cells 1 , and two insulating tapes are applied to the battery cells 1 by two gluing devices, which can provide more comprehensive protection for the battery cells 1 and help further improve the safety of the battery cells 1 .

[0048] On the basis of the above embodiment, as an optional implementation, the gluing production line further includes a mounting frame 200, the first gluing device 100a and the second gluing device 100b are both arranged on the mounting frame 200, and the spacing between the glue disc 11 of the first gluing device 100a and the glue disc 11 of the second gluing device 100b along the width direction of the battery cell 1 is adjustable. Specifically, the first gluing device 100a can be installed on the mounting frame 200 through the first adjustment hole 210 and the first adjustment member (not shown in the figure), the first adjustment hole 210 can be a waist-shaped hole or an elliptical hole arranged along the width direction of the battery cell 1, the first adjustment member passes through the first adjustment hole 210 to fix the first gluing device 100a on the mounting frame 200, and by adjusting the position of the first adjustment member in the first adjustment hole 210, the first gluing device 100a is moved along the width direction of the battery cell 1, thereby driving the glue disc 11 of the first gluing device 100a to move along the width direction of the battery cell 1. The second gluing device 100b can be installed on the mounting frame 200 through the second adjustment hole and the second adjustment member (not shown in the figure). The second adjustment hole can be a waist-shaped hole or an elliptical hole set along the width direction of the battery cell 1. The second adjustment member passes through the second adjustment hole to fix the second gluing device 100b on the mounting frame 200, and by adjusting the position of the second adjustment member in the second adjustment hole, the second gluing device 100b is moved along the width direction of the battery cell 1, thereby driving the glue disc 11 of the second gluing device 100a to move along the width direction of the battery cell 1. Therefore, by setting the spacing between the glue disc 11 of the first gluing device 100a and the glue disc 11 of the second gluing device 100b along the width direction of the battery cell 1 to be adjustable, the gluing device can be applied to batteries of different widths, and batteries of different widths can be glued at the same position, so that the application range of the gluing production line is wider.

[0049] On the basis of the above embodiment, as an optional implementation, the glue production line also includes a cell transfer assembly 400 and a cell tray assembly 500, both of which are installed on the mounting frame 200. Among them, the cell transfer assembly 400 is arranged at the downstream end of the second glue sticking device 100b, and the cell tray assembly 500 is arranged at the downstream end of the cell transfer assembly 400. The cell transfer assembly 400 is used to transfer the glued cell 1 to the cell tray assembly 500, and the cell tray assembly 500 is used to load the glued cell, so as to facilitate the unloading of the glued cell. Therefore, after the glue is applied to the cell 1, the glued cell 1 can be transferred to the cell tray assembly 500 for unloading, and the automatic glue application of the cell can be realized without human intervention to assist the glue application, which reduces the cost of glue application, improves the efficiency of glue application, and can ensure the consistency of glue application, and better guarantee the quality of glue application.

[0050] Based on the above embodiment, as an optional implementation mode, Figures 8 to 10 As shown, the gluing production line also includes a conveying component 300, which is arranged on one side of the placement platform 20 along the length direction of the battery cell 1. The conveying component 300 includes a plurality of material picking parts 310, and the material picking parts 310 and the placement platform 20 are arranged relative to each other along the third direction. The battery cell 1 is located between the material picking parts 310 and the placement platform 20. The material picking parts 310 can move along the width direction and the thickness direction of the battery cell 1. The material picking parts 310 are used to transfer the battery cell 1 to be glued to the placement platform 20 of the first gluing device 100a. The material picking parts 310 are also used to transfer the battery cell 1 on the placement platform 20 of the first gluing device 100a to the placement platform 20 of the second gluing device 100b, and to transfer the glued battery cell 1 on the placement platform 20 of the second gluing device 100b to the battery cell transfer component 400. Thus, the battery cell 1 to be glued can be transferred to the gluing device 100 through the transport component 300, and the battery cell 1 after gluing can be transferred to the battery cell transfer component 400, which reduces manual intervention and is conducive to further improving the efficiency of battery cell gluing. As an optional embodiment, multiple material picking members 310 are arranged on the transport bracket 320, and the transport bracket 320 can simultaneously drive multiple material picking members 310 to move along the width direction and thickness direction of the battery cell 1, and multiple material picking members 310 can also independently move along the thickness direction of the battery cell 1, so that each material picking member 310 can independently transport the battery cell 1.

[0052] Based on the above embodiment, as an optional implementation mode, Figure 7As shown, the glue sticking production line also includes a detection component 600, which is fixedly arranged at the battery cell transfer component 400. The detection component 600 is used to detect the sticking of the insulating tape on the battery cell, and can mark or record the battery cells that are not stuck with insulating tape, or the battery cells that are less stuck with insulating tape, or the battery cells that are not stuck with insulating tape, so as to remove them before loading, avoid the battery cells with poor glue sticking from flowing to subsequent stations, which is conducive to improving the quality of glue sticking. As an optional embodiment, the detection component 600 can be a CCD detection camera, and the CCD detection camera performs detection by taking pictures.

[0053] Based on the above embodiment, as an optional implementation, the cell transfer assembly 400 can use a cell transfer driver and a belt to transfer the cell, the glued cell 1 is placed on the belt, and the cell transfer driver is used to drive the belt to move, so as to transport the glued cell 1 to the cell tray assembly 500. Of course, those skilled in the art can also select a conventional cell transfer assembly 400 in the art to transfer the cell.

[0054] On the basis of the above embodiment, as an optional implementation, the battery cell tray assembly 500 includes a tray loading station 510 and an empty tray station 520 arranged at intervals along the length direction of the battery cell 1. The tray loading station 510 has multiple layers of empty trays stacked along the thickness direction of the battery cell 1. The tray loading station 510 has multiple layers of trays stacked along the thickness direction of the battery cell 1. The battery cell transfer assembly 400 transfers the battery cell 1 after gluing to the tray of the tray loading station 510. After the trays of the tray loading station 510 are filled with the battery cell 1 after gluing, the tray of the tray loading station 510 can be transported to the next station. The tray transfer assembly transfers the tray at the empty tray station 520 to the tray loading station 510, and continues the tray loading of the battery cell 1 after gluing.

[0057] Step S110: placing the battery cell to be glued on the placement platform 20 of the first glue sticking device 100a, and the first glue sticking device 100a sticks the first insulating tape on both ends of the battery cell in the length direction.

[0058] Specifically, the material picking component 310 transfers the battery cell 1 to be glued to the placement platform 20 of the first glue sticking device 100a, and the two piezoelectric cell components 30 of the first glue sticking device 100a respectively support the head of the battery cell 1 and the tail of the battery cell 1, and the adsorption holes 111 on the glue disc 11 adsorb the first insulating tape, and the glue discs 11 on the two glue sticking components 10 respectively move along the length direction of the battery cell 1, so that one glue disc 11 is accommodated in the first notch 21, and the other glue disc 11 is accommodated in the second notch 22, and the two glue discs 11 move relative to each other along the length direction of the battery cell 1, and the two first insulating tapes are respectively attached to the lower surface of the head and the lower surface of the tail of the battery cell 1, and then, the two glue discs 11 move oppositely along the length direction of the battery cell 1, and withdraw from the first notch 21 and the second notch 22 respectively, and the two glue discs 11 Along the thickness direction of the battery cell 1, the first insulating tape is respectively attached to the end surface of the head and the end surface of the tail of the battery cell 1. Subsequently, the two rubber discs 11 move relative to each other along the length direction of the battery cell 1, and the two rubber discs 11 pass through the third notch 32 on the pressing plate 31. The two rubber discs 11 continue to move relative to each other along the length direction of the battery cell 1, and the first insulating tape on the rubber disc 11 is respectively attached to the upper surface of the head and the upper surface of the tail of the battery cell 1. The cutter 112 accommodated in the rubber disc 11 moves along the length direction of the battery cell 1, extends from the fourth notch 113, and cuts off the first insulating tape. Subsequently, the cutter 112 moves along the length direction of the battery cell 1 and is accommodated inside the rubber disc 11. The two rubber discs 11 move oppositely along the length direction of the battery cell 1 and withdraw from the third notch 32, thereby completing the gluing of the upper and lower surfaces of the head and tail of the battery cell 1.

[0059] Step S120, placing the battery cell 1 with the first insulating tape on the placement platform 20 of the second gluing device 100b, the second gluing device 100b applies the second insulating tape to both ends of the battery cell 1 along the length direction, and the first insulating tape and the second insulating tape are spaced apart by a preset distance along the width direction of the battery cell 1.

[0060] Specifically, the material picking piece 310 transfers the battery cell 1 on the placement platform 20 of the first gluing device 100a to the placement platform 20 of the second gluing device 100b, and the second gluing device 100b applies the second insulating tape to both ends of the battery cell 1 along the length direction. The specific steps of the second gluing device 100b applying the second insulating tape to the battery cell 1 are the same as the specific steps of the first gluing device 100a applying the first insulating tape to the battery cell 1 in step S110, which will not be repeated here.

[0061] It should be noted that in this embodiment, the preset spacing between the first insulating tape and the second insulating tape along the width direction of the battery cell 1 is not further limited. Those skilled in the art can set it according to the size of the battery cell 1. In some optional embodiments, the preset spacing can be 0.

[0062] Step S130, the glued battery cells are sequentially loaded and unloaded to complete the glue-sticking of the battery cells.

[0063] Specifically, the material picking component 310 transfers the glued battery cell 1 on the placement platform 20 of the second glue laminating device 100b to the battery cell transfer component 400, and the detection component 600 detects the lamination condition of the insulating tape on the battery cell 1. The battery cell 1 that passes the detection is transferred to the battery cell tray assembly 500 through the battery cell transfer component 400, and the battery cell 1 is unloaded after being turned on the tray.

[0064] The gluing method provided in this embodiment can perform double-sided gluing on both the head and the tail of the battery cell, and can realize automatic gluing operation without the need for human intervention to assist in gluing, thereby reducing the cost of gluing, improving the efficiency of gluing, and ensuring the consistency of gluing, thereby better ensuring the quality of gluing.

[0065] In this embodiment, the first glue disc driver 12, the second glue disc driver 13, the pressure plate driver 32, the first transport driver 330, the second transport driver 340 and the battery cell transfer driver can adopt cylinders or motors, and the first glue disc driver 12, the second glue disc driver 13, the pressure plate driver 32, the first transport driver 330, the second transport driver 340 and the battery cell transfer driver can also be matched with mechanical transmission structures such as screw rods, gears, cylinders, chains or synchronous belts to better drive. As an optional embodiment, the first glue disc driver 12 can cooperate with the motor and the screw rod to drive the glue disc 11 to move along the length direction of the battery cell 1, which is conducive to improving the positioning accuracy of the glue disc 11 for feeding glue, and the glue sticking effect is better and the glue sticking is more stable.
