[0065] Unless otherwise defined, the technical or scientific terms used herein shall have the common meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the patent application specification and claims of the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "a" do not indicate a quantity limitation, but indicate the existence of at least one.

[0066] like Figures 1 to 9 As shown, it is a preferred embodiment provided by the present invention.

[0067] The present embodiment provides a gluing device for gluing a tape to a surface of a battery cell, wherein the tape 200 includes an adhesive tape and a release paper, wherein the adhesive tape has a first surface and a second surface opposite to each other, and the release paper is attached to the second surface, wherein the gluing device includes: a support frame 10 and a gluing mechanism 30, a gluing mechanism 20, a gluing mechanism 50 and a gluing mechanism 60 arranged on the support frame 10; the gluing mechanism 30 includes a gluing rod 31 for abutting against the first surface of the adhesive tape 200; the gluing mechanism 20 includes a gluing assembly 24 for clamping the tape at a first position S1 200, pull the tape 200 to a second position S2, and separate from the tape 200 after the glue rod 31 abuts against the tape 200, and move to the first position S1 to clamp the tape 200; the laminating mechanism 50 is used to grab the tape 200 and move the tape 200 to the surface of the battery cell (not shown), the laminating mechanism 50 includes an adsorption component 54, which is used to adsorb the release paper side of the tape 200; the glue cutting mechanism 60 is used to cut the tape 200 located between the adsorption component 54 and the glue clamping component 24 after the adsorption component 54 adsorbs the tape 200.

[0068] The above-mentioned adhesive sticking device for sticking adhesive tape on the surface of the battery cell adopts an adhesive setting mechanism 30, an adhesive clamping mechanism 20, an adhesive bonding mechanism 50 and an adhesive cutting mechanism 60. The adhesive setting mechanism 30 includes an adhesive setting rod 31 that abuts against the first adhesive surface of the adhesive tape 200. The adhesive clamping mechanism 20 includes an adhesive clamping assembly 24. The adhesive clamping assembly 24 clamps the adhesive tape 200 at a first position S1 and pulls the adhesive tape 200 to a second position S2. After the adhesive setting rod 31 abuts against the adhesive tape 200, it separates from the adhesive tape 200 and moves to the first position S1 to clamp the adhesive tape 200. In this way, the adhesive clamping assembly 24 The adhesive tape 200 is clamped and pulled to the second position S2, and the adhesive rod 31 is separated from the adhesive tape 200 after being bonded to the adhesive tape 200, and then reset to the first position S1 to clamp the adhesive tape 200, and the adsorption component 54 adsorbs the adhesive tape 200, and the adhesive cutting mechanism 60 cuts the adhesive tape 200 at the same time, and the cut adhesive tape 200 is sucked by the adsorption component 54, and because the free end of the cut adhesive tape 200 is clamped by the adhesive clamping component, the free end of the cut adhesive tape 200 will not fall off and does not need to be clamped again, thereby ensuring the continuity of adhesive application and improving production efficiency.

[0069] See also Figures 1 to 9 The present embodiment provides a glue sticking device for sticking adhesive tape on the surface of a battery cell, which includes a support frame 10 and a glue setting mechanism 30, a glue clamping mechanism 20, a bonding mechanism 50 and a glue cutting mechanism 60 arranged on the support frame 10. The support frame 10 is mounted on and supported by the mounting substrate 101. The adhesive tape 200 is wound in the form of a film roll and is arranged on a discharge wheel not shown in the figure. The glue clamping mechanism 20 is mainly used to clamp the adhesive tape 200 and pull the adhesive tape 200 to move to achieve glue feeding. The glue sticking method in this embodiment is to place the cut adhesive tape 200 downward on the surface of the battery cell to be glued. The adhesive tape 200 includes an adhesive tape and a release paper. The adhesive tape has a first and a second opposite surface. The first surface is a downward lower surface (the lower surface shown in the figure), and the second surface is an upward upper surface. The first surface and the second surface are both adhesive surfaces with stickiness, and the release paper is attached to the second surface. It is worth mentioning that the adhesive tape 200 can be a foam tape with an EVA (ethylene-vinyl acetate copolymer) substrate, or a double-sided tape with a PET (polyethylene glycol terephthalate) substrate. When the adhesive tape 200 is a foam tape, its structure is a foam adhesive tape and release paper attached to the front and back sides of the foam adhesive tape. In the actual operation process, before the adhesive tape 200 is clamped by the clamping mechanism 20, the release paper attached to the lower surface of the foam adhesive tape needs to be peeled off by the release paper separation mechanism (not shown); when the adhesive tape 200 is a double-sided tape, its structure is an adhesive tape and a release paper attached to the outer side of the adhesive tape when winding. In the actual operation process, before the adhesive tape 200 is clamped by the clamping mechanism 20, the release paper side of the adhesive tape 200 is set upward.

[0070] See also Figures 1 to 9 The glue clamping mechanism 20 is used to clamp the adhesive tape 200 at a first position S1, pull the adhesive tape 200 to a second position S2 along a glue feeding direction, separate from the adhesive tape 200 after the glue fixing rod 31 abuts against the adhesive tape 200, and clamp the adhesive tape 200 again after moving to the first position S1 in a direction opposite to the glue feeding direction. It includes a glue pulling rail 21, a glue pulling sliding seat 22, a sliding seat driving assembly 23 and a glue clamping assembly 24.

[0071] from Figures 1 to 9 It can be seen that the glue drawing rail 21 is installed at the bottom of the support frame 10, the glue drawing sliding seat 22 is slidably arranged on the glue drawing rail 21, and can move left and right (left and right in the figure) relative to the support frame 10, and the sliding seat driving assembly 23 can drive the glue drawing sliding seat 22 to move. In this embodiment, the sliding seat driving assembly 23 includes a sliding screw 231, a sliding nut seat 232 connected to the sliding screw 231, and a sliding driving member 233 that rotates the sliding screw 231. The glue drawing sliding seat 22 is fixedly connected to the sliding nut seat 232. The sliding driving member 233 is but not limited to a stepping motor. It is easy to understand that under the drive of the sliding driving member 233, the sliding screw 231 rotates, and the sliding nut seat 232 drives the glue drawing sliding seat 22 to move left and right relative to the support frame 10. It is worth mentioning that the glue feeding direction is parallel to the extension direction of the glue pulling rail 21, and the first position S1 is the initial position of the glue sandwich assembly 24, and the second position S2 is located on the left side of the first position S1 (the left side in the figure), which is the end position; according to the different sizes of battery cells, different lengths of the adhesive tape 200 are selected (the length dimension is the length dimension in the glue feeding direction), and the second position S2 does not change. By adjusting the first position S1, the glue pulling length from the first position S1 to the second position S2 can be adjusted, thereby adjusting the length dimension to match.

[0072] As a further optimization, a photoelectric switch for detecting the position of the glue-pulling sliding seat 22 is provided on the support frame 10, and a sensor sheet used in conjunction with the photoelectric switch is provided on the glue-pulling sliding seat 22. The photoelectric switch is located below the glue-pulling horizontal rail 21 (below the figure). Specifically, the opening and closing and forward and reverse rotation of the sliding drive 233 are controlled by a controller (not shown in the figure). The controller is any existing controller that can realize the control of the sliding drive 233. The photoelectric switch and the sensor sheet used in conjunction with it are used to detect the position of the glue-pulling sliding seat 22 to control the sliding drive 233 to perform corresponding operations.

[0073] See also Figures 1 to 9The adhesive clamping assembly 24 is used to clamp the adhesive tape 200, and the adhesive clamping assembly 24 is fixedly arranged on the adhesive pulling sliding seat 22. In this embodiment, the adhesive clamping assembly 24 includes an upper clamping plate 241, a lower clamping plate 242 arranged opposite to the upper clamping plate 241, a clamping plate driving member 243 for driving the upper clamping plate 241 and the lower clamping plate 242 to move relative to each other, and an adhesive clamping connection bracket 244 fixedly connected between the clamping plate driving member 243 and the adhesive pulling sliding seat 22. The clamping plate driving member 243 is but not limited to a cylinder. Under the drive of the sliding seat driving assembly 23, the glue pulling sliding seat 22 moves to the right end portion of the glue pulling rail 21 (the right end in the figure), which is the starting position (i.e., the first position S1). The upper clamping plate 241 and the lower clamping plate 242 of the glue pulling assembly 24 are closed under the action of the clamping plate driving member 243, and the tape 200 is clamped from the upper and lower surfaces of the tape 200 (the upper and lower surfaces in the figure). After clamping, it is driven by the sliding seat driving assembly 23 to move to the left end portion of the glue pulling rail 21 (the left end in the figure), which is the ending position (i.e., the second position S2). It is easy to understand that the stroke between the ending position and the starting position is the dragging length of the tape 200. The required glue sticking length can be selected according to the length of the battery cell. In other words, the ending position can be changed according to the required glue sticking length.

[0074] from Figures 1 to 9 It can be seen that the adhesive connection bracket 244 includes a first vertical section 2441 extending upward (upper side in the figure) from the surface of the adhesive sliding seat 22, a horizontal section 2442 extending outward (in the figure, in the right direction orthogonal to the extension direction of the adhesive horizontal rail 21) from the first vertical section 2441 and perpendicular to the extension direction of the adhesive horizontal rail 21, and a second vertical section 2443 extending upward (upper side in the figure) from the horizontal section 2442, and the clamping plate driving member 243 is fixed on the second vertical section 2443. In this way, the adhesive connection bracket 244 adopts a bending extension structure of the first vertical section 2441, the horizontal section 2442, and the second vertical section 2443, which can ensure that it avoids the adhesive tape 200 when moving, and the installation area between the clamping plate driving member 243 and the adhesive connection bracket 244 and between the adhesive connection bracket 244 and the adhesive sliding seat 22 is large, and the connection reliability is high.

[0075] See also Figures 1 to 9The glue fixing mechanism 30 includes a glue fixing rod 31 used to abut against the first adhesive surface of the adhesive tape 200 before the glue clamping assembly 24 is separated from the adhesive tape 200. In this embodiment, the glue fixing rod 31 is a thin rod with a smaller diameter and is located below the adhesive tape 200, and is used to contact the adhesive tape 200 upward and adhere to each other after contact. After the glue clamping assembly 24 clamps the adhesive tape 200, it is in surface contact with the surface of the adhesive tape 200, so that the adhesive tape 200 will not fall off when the adhesive tape 200 is dragged; due to the small diameter of the glue fixing rod 31, after the glue fixing rod 31 contacts the adhesive tape 200, the two are in linear contact, so that the cut adhesive tape 200 is separated from the glue fixing rod 31 when it is grabbed by the adsorption assembly. It is worth mentioning that, when the glue clamping assembly 24 pulls the adhesive tape 200 to the preset position (i.e., the end position, the second position S2), the glue rod 31 moves up and adheres to the adhesive surface of the adhesive tape 200. At this time, the upper clamping plate 241 and the lower clamping plate 242 are opened and separated from the adhesive tape 200. After the sliding seat driving assembly 23 moves to the starting position (i.e., the first position S1), the upper clamping plate 241 and the lower clamping plate 242 are closed and clamp the adhesive tape 200. The adhesive tape 200 between the glue rod 31 and the glue clamping assembly 24 can be sucked downward by the suction head 541, and the adhesive tape 200 is cut by the cutter set between the glue clamping assembly 24 and the suction head 541. The cut adhesive tape 200 is grabbed by the suction head 541 and placed downward on the surface of the battery cell to be glued. Since the adhesive tape 200 is clamped by the glue clamping assembly 24, repeating the above operation can ensure continuous glue feeding, improve the continuity of glue sticking, and production efficiency.

[0076] Please continue to see Figures 1 to 9 , the glue fixing mechanism 30 also includes a rod mounting seat 32 connected and fixed to the glue fixing rod 31 and a rod driving member 33 for driving the rod mounting seat 32 to move up and down relative to the support frame 10. In this embodiment, the rod driving member 33 is but not limited to a cylinder. A rod adjustment rail 34 is provided on the support frame 10. The extension direction of the rod adjustment rail 34 is parallel to the extension direction of the glue pulling rail 21. The rod mounting seat 32 is slidably set on the rod adjustment rail 34; a rod adjustment assembly 35 is provided between the rod mounting seat 32 and the support frame 10 so that the two can move relative to each other. It is easy to understand that after selecting the required glue sticking length according to the length of the battery cell, the end position of the glue clamping assembly 24 will be changed and adjusted according to the required glue sticking length. Therefore, the position of the glue fixing rod 31 in the extension direction of the glue pulling rail 21 also needs to be adjusted accordingly.

[0077] Specifically, the rod adjustment assembly 35 includes a rod adjustment seat 351, a rod adjustment shaft 352 rotatably supported on the rod adjustment seat 351, and an operating member 353 connected to the rod adjustment shaft 352. The rod mounting seat 32 is provided with an adjustment hole for the rod adjustment shaft 352 to be inserted. The outside of the rod adjustment shaft 352 is formed with an external threaded portion, and the inside of the adjustment hole is formed with a threaded mating portion that is threadedly mated with the external threaded portion. In this way, by twisting the operating member 353, the rod mounting seat 32 can be driven to move left and right (left and right as shown in the figure), thereby facilitating the adjustment of the position of the rod mounting seat 32.

[0078] See also Figures 1 to 9 The lower clamping plate 242 is provided with a glue fixing groove 2421 for the glue fixing rod 31 to pass through. The glue fixing groove 2421 extends from the middle of the top surface of the lower clamping plate 242 to the periphery of the top surface, and penetrates the top surface and the bottom surface of the lower clamping plate 242. The lower clamping plate 242 includes a lower clamping portion 2422 and a lower clamping mounting portion 2423 connected to each other. The lower clamping mounting portion 2423 is connected to the clamping plate driving member 243. The glue fixing groove 2421 is located on the lower clamping portion 2422. The glue fixing groove 2421 extends from one end of the lower clamping portion 2422 connected to the lower clamping mounting portion 2423 to the other end of the lower clamping portion 2422 opposite to the one end connected to the lower clamping mounting portion 2423 (the left end in the figure). In this way, when the glue sandwich assembly 24 moves to the corresponding position above the glue fixing rod 31 , the rod driving member 33 drives the glue fixing rod 31 to move upward, and slides into the glue fixing groove 2421 to adhere to the lower surface of the tape 200 .

[0079] In another embodiment, the bottom surface of the upper clamping plate 241 is larger than the top surface of the lower clamping plate 242 , and the adhesive rod 31 moves upward from the outer side of the lower clamping plate 242 to abut against the adhesive tape 200 .

[0080] See also Figures 1 to 9 The laminating mechanism 50 is used to grab the tape 200 and move the tape 200 to the surface of the battery cell. In the present embodiment, the laminating mechanism 50 includes a laminating rail 51, a laminating movable seat 52, a movable seat driving assembly 53 and an adsorption assembly 54. The laminating rail 51 is arranged on the support frame 10 and is located above the glue clamping mechanism 20, and is arranged parallel to the glue pulling rail 21. The laminating movable seat 52 is slidably arranged on the laminating rail 51. The movable seat driving assembly 53 can move the laminating movable seat 52. The adsorption assembly 54 is used to adsorb the tape 200 and laminar the tape 200 on the surface of the battery cell. The adsorption assembly 54 is arranged on the laminating movable seat 52.

[0081] See also Figures 1 to 9The adsorption assembly 54 includes an adsorption head 541 and an adsorption head driving member 542 for driving the adsorption head 541 to move up and down relative to the fitting movable seat 52. The adsorption head 541 has a plurality of adsorption channels respectively connected to the vacuum device (not shown), one end of each adsorption channel extends to the bottom surface of the adsorption head 541, and respectively forms adsorption holes 543. In the present embodiment, the adsorption head driving member 542 is but not limited to a cylinder, the adsorption head 541 has a gas cavity 544 opening upward, the gas cavity 544 is connected to the vacuum device through a joint, a plurality of adsorption channels are spaced apart from each other, and are respectively arranged vertically, one end of each adsorption channel extends to the bottom surface of the adsorption head 541, and respectively forms adsorption holes 543, and the other end extends to the bottom surface of the gas cavity 544, and is connected to the gas cavity 544. It is worth mentioning that the spacing between the multiple adsorption holes 543 is basically the same. By setting multiple adsorption channels on the adsorption head 541, multiple adsorption holes 543 evenly distributed are formed on the bottom surface of the adsorption head 541, which has the advantages of strong adsorption force, good adsorption stability, and stable force on each adsorption point.

[0082] See also Figures 1 to 9 The moving seat driving assembly 53 includes a moving screw 531, a moving nut seat 532 connected to the moving screw 531, and a moving driving member 533 for rotating the moving screw 531. The fitting moving seat 52 is fixedly connected to the moving nut seat 532. The moving driving member 533 is but not limited to a stepping motor. It is easy to understand that under the drive of the moving driving member 533, the moving screw 531 rotates, and the moving nut seat 532 drives the fitting moving seat 52 to move left and right relative to the support frame 10.

[0083] As a further optimization, a photoelectric switch for detecting the position of the bonding movable seat 52 is provided on the support frame 10, and a sensor sheet (not shown) used in conjunction with the photoelectric switch is provided on the bonding movable seat 52. The photoelectric switch is located above the bonding horizontal rail 51 (above the figure). Specifically, the opening and closing and forward and reverse rotation of the mobile driving member 533 are controlled by a controller (not shown). The controller is any existing controller that can realize the control of the mobile driving member 533. The photoelectric switch and the sensor sheet used in conjunction with it are used to detect the position of the bonding movable seat 52 to control the mobile driving member 533 to perform corresponding operations.

[0084] See also Figures 1 to 9, the adsorption assembly 54 is escalably arranged on the fitting movable seat 52, and the fitting mechanism 50 further includes a height adjustment assembly 56, which is used to drive the adsorption assembly 54 to move up and down relative to the fitting movable seat 52. In this embodiment, the height adjustment assembly 56 includes an adjustment longitudinal rail 561, an adsorption lifting seat 562, and a lifting drive 563, the adjustment longitudinal rail 561 is arranged on the fitting movable seat 52, the adsorption lifting seat 562 is slidably arranged on the adjustment longitudinal rail 561, the adsorption assembly 54 is fixedly connected to the adsorption lifting seat 562, and the lifting drive 563 enables the adsorption lifting seat 562 to move up and down relative to the fitting movable seat 52. The longitudinal rail 561 is adjusted to extend in the vertical direction (the up and down direction as shown in the figure), and the lifting drive member 563 is but not limited to a cylinder. It should be understood that, in the process of grabbing and placing the tape 200 by the bonding mechanism 50, it is mainly the suction head drive member 542 of the adsorption assembly 54 that drives the adsorption head 541 to move up and down (the up and down direction as shown in the figure), and the lifting displacement of the adsorption head 541 (that is, the stroke of the adsorption head drive member 542) is a preset value; when the tape 200 is replaced, the height (the distance between the bottom surface of the support seat and the top surface of the tape 200) of the adsorbed surface (that is, the top surface of the tape 200) of the tape 200 made of different materials will change due to its different thickness. After the adsorption assembly 54 is driven by the height adjustment assembly 56 to move up and down (the up and down direction as shown in the figure) relative to the bonding movable seat 52, the height of the adsorption assembly 54 is adapted to the tape 200, thereby ensuring the accuracy of the adsorption, and the adsorption and placement process of the tape 200 is smoother and more reliable.

[0085] Specifically, the lifting drive member 563 has an output shaft. The lifting drive member 563 is fixedly mounted on the fitting moving seat 52 via a retaining sheet 564 . The output shaft of the lifting drive member 563 is connected and fixed to the adsorption lifting seat 562 via a connecting rod 565 .

[0086] See also Figures 1 to 9 The adhesive cutting mechanism 60 is used to cut the adhesive tape 200 between the adsorption component 54 and the adhesive laminating component 24 after the adsorption component 54 adsorbs the adhesive tape 200. In this embodiment, the adhesive cutting mechanism 60 includes an upper cutter component 61 and a lower cutter component 62 which are arranged opposite to each other. The upper cutter component 61 is connected to an upper cutter driving component 63, and the lower cutter component 62 is connected to a lower cutter driving component 64. It is easy to understand that under the drive of the upper cutter driving component 63 and the lower cutter driving component 64, the upper cutter component 61 and the lower cutter component 62 move toward each other and cut the adhesive tape 200.

[0087] Please continue to see Figures 1 to 9 The upper cutter member 61 has a guide extension portion, and the lower cutter member 62 abuts against the guide extension portion. The guide extension portion abuts against the side of the lower cutter member 62. When the two move relative to each other, they can guide the two to avoid collision of the blades.

[0088] See also Figures 1 to 9 , a distance adjusting device 70 is connected between the bottom of the support frame 10 and the mounting substrate 101 to adjust the relative position of the two. In this embodiment, the distance adjusting device 70 includes a distance adjusting base frame 71 fixed on the mounting substrate 101, and the distance adjusting base frame 71 has a distance adjusting space 72 for the support frame 10 to slide, and a distance adjusting shaft (not shown) is arranged on the distance adjusting base frame 71, and the two are connected by threads, and the distance adjusting shaft is connected and fixed to the support frame 10.
