[0061] like Figures 1 to 16 As shown, it is a preferred embodiment provided by the present invention.

[0062] The cell gluing machine 1000 provided in this embodiment is used to glue the surface of the cell 300, and includes a mounting substrate 101, a cell transfer device 400 and a gluing device 100. The surface of the mounting substrate 101 has a transverse direction (the D1 direction shown in the figure, hereinafter collectively referred to as the first direction D1) and a longitudinal direction (the D2 direction shown in the figure, hereinafter collectively referred to as the second direction D2) perpendicular to each other. The cell transfer device 400 is used to move the cell 300 in a direction parallel to the first direction D1, and the gluing device 100 is used to transfer the cell 300 to the mounting substrate 101. The battery cell 300 on the device 400 is glued; the glue sticking device 100 includes a support frame 10, a glue clamping mechanism 20, a glue cutting mechanism 60, a bonding mechanism 50 and a release paper separation mechanism 40, the glue clamping mechanism 20 is used to pull the tape 200 in a direction parallel to the second direction D2; the glue cutting mechanism 60 is used to cut the tape 200, the bonding mechanism 50 is used to attach the cut tape 200 to the battery cell 300 located on the battery cell transfer device 400, and the release paper separation mechanism 40 is used to recycle the release paper of the tape 200.

[0063] The above-mentioned battery cell gluing machine 1000 includes a battery cell transferring device 400 and a gluing device 100. The gluing device 100 includes a support frame 10, a glue clamping mechanism 20, a glue cutting mechanism 60, a laminating mechanism 50 and a release paper separating mechanism 40. It has a high degree of automation, reduces production costs and improves production efficiency.

[0064] See also Figure 1 and 2 The battery cell gluing machine 1000 of this embodiment includes a mounting substrate 101, a battery cell transferring device 400 and a gluing device 100. The mounting substrate 101 is roughly rectangular, and the battery cell transferring device 400 and the gluing device 100 are both supported on the mounting substrate 101.

[0065] See also Figures 1 to 4 The battery cell transfer device 400 is used to move the battery cell 300 along a direction parallel to the first direction D1, and includes a transfer bracket 401, an active roller (not shown), a driven roller (not shown), a moving belt 402, a moving belt drive assembly 403, a limit grab seat 404, a top support component 405 and a top support drive component 406. The active roller and the driven roller are rotatably supported on the transfer bracket 401, respectively. The moving belt 402 is wrapped between the active roller and the driven roller and is used to place the battery cell 300; the moving belt drive assembly 403 is used to rotate the active roller, and the moving belt drive assembly 403 is but not limited to a motor drive assembly.

[0066] from Figure 4It can be seen that the limiting grabbing seat 404 is fixed on one end of the moving bracket, and the limiting grabbing seat 404 has a first side 4041 (right side as shown in the figure), a second side 4042 (rear side as shown in the figure), a third side 4043 (front side as shown in the figure) and a fourth side 4044 (left side as shown in the figure) connected in sequence, wherein the first side 4041 faces the transfer bracket 401, the third side 4043 is opposite to the first side 4041, and the second side 4042 is opposite to the fourth side 4044; a limiting base groove 4045 is provided on the top surface of the limiting grabbing seat 404 for the power supply core 300 to slide into, and the limiting base groove 4045 extends from the middle of the top surface of the limiting grabbing seat 404 to the periphery of the first side 4041 and the periphery of the fourth side 4044, and the bottom surface of the limiting base groove 4045 is flush with the top surface of the moving belt 402. The top supporting driving member 406 is used to make the top supporting member 405 move up and down relative to the position limiting grab seat 404; the position limiting grab seat 404 is provided with a top supporting slide 4046 for the top supporting member 405 to slide, and the top supporting slide 4046 penetrates the bottom surface of the position limiting base groove 4045 and the bottom surface of the position limiting grab seat 404, and extends from the middle of the bottom surface of the position limiting base groove 4045 to the periphery of the fourth side 4044. It can be understood that the position limiting grab seat 404 can receive the battery cell 300 moved by the moving belt 402, and allow the battery cell 300 to slide into the position limiting base groove 4045, and use the side wall of the position limiting base groove 4045 to limit and position the battery cell 300, so as to facilitate the gluing of the gluing device 100. In particular, after the top surface of the battery cell 300 (the upper surface shown in the figure) is glued, the top support driving member 406 drives the top support member 405 to move downward and separate from the battery cell 300, so that the battery cell 300 can be grasped from the fourth side 4044 by an external robot, thereby removing the battery cell 300 from the battery cell transfer device 400.

[0067] See also Figure 1 , 2 , 5 to 14, the glue sticking device 100 provided in this embodiment is used for sticking glue on the battery cells 300 on the battery cell transfer device 400, and includes a support frame 10 and a glue fixing mechanism 30, a glue clamping mechanism 20, a bonding mechanism 50 and a glue cutting mechanism 60 arranged on the support frame 10, and the support frame 10 is installed on the mounting substrate 101 and supported by the mounting substrate 101.

[0068] The unloading wheel 11 is rotatably supported on the top of the support frame 10, and the tape 200 is arranged on the unloading wheel 11 in the form of a wound film roll. The glue clamping mechanism 20 is mainly used to clamp the tape 200 and pull the tape 200 to move to achieve glue feeding. The glue sticking method in this embodiment is to place the cut tape 200 downward on the surface of the battery cell to be glued. The tape 200 includes an adhesive tape and a release paper. The adhesive tape has a first surface and a second surface opposite to each other. 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 adhesive, and the release paper is attached to the second surface. It is worth mentioning that the tape 200 can be a foam tape with a substrate of EVA (ethylene-vinyl acetate copolymer) or a double-sided tape with a substrate of PET (polyethylene glycol terephthalate). When the tape 200 is a foam tape, its structure is a foam tape and a release paper attached to the front and back sides of the foam tape. During actual operation, before the clamping mechanism 20 clamps the tape 200, it is necessary to first peel off the release paper attached to the lower surface of the foam tape through the release paper separation mechanism 40; when the tape 200 is a double-sided tape, its structure is an adhesive tape and a release paper attached to the outside of the adhesive tape when winding. During actual operation, before the clamping mechanism 20 clamps the tape 200, the release paper side of the tape 200 is set upward.

[0069] See also Figure 1 , 2 , 5 to 14, the glue clamping mechanism 20 is used for, after clamping the adhesive tape 200 at a first position S1, pulling the adhesive tape 200 to a second position S2 along a glue feeding direction (i.e., extending in a direction parallel to the second direction D2), and separating from the adhesive tape 200 after the glue fixing rod 31 abuts against the adhesive tape 200, and clamping the adhesive tape 200 again after moving to the first position S1 in a direction opposite to the glue feeding direction, which includes a glue pulling rail 21, a glue pulling sliding seat 22, a sliding seat driving assembly 23 and a glue clamping assembly 24.

[0070] from Figure 1 , 2As can be seen from Figures 5 to 14, the glue-drawing rail 21 is installed at the bottom of the support frame 10, and the glue-drawing rail 21 extends in a direction parallel to the second direction D2. 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, and 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 battery cells of different sizes, different lengths of the adhesive tape 200 are selected (the length dimension is the length dimension in the glue feeding direction, that is, the dimension in the direction parallel to the second direction D2), and the second position S2 is unchanged. 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.

[0071] 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 member 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 member 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 member 233 to perform corresponding operations.

[0072] See also Figure 1 , 2, 5 to 14, the 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 used to drive 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), and 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 dimension of the battery cell (the dimension in the direction parallel to the second direction D2). In other words, the ending position can be changed according to the required glue sticking length.

[0073] from Figure 1 , 2 As can be seen from Figures 5 to 14, 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.

[0074] See also Figure 1 , 2, 5 to 14, the glue fixing mechanism 30 includes a glue fixing rod 31 used to abut against the first adhesive surface of the tape 200 before the glue clamping assembly 24 is separated from the tape 200. In this embodiment, the glue fixing rod 31 is a thin rod with a smaller diameter and is located below the tape 200, and is used to contact the tape 200 upward and adhere to each other after contact. After the glue clamping assembly 24 clamps the tape 200, it is in surface contact with the surface of the tape 200, so that the tape 200 will not fall off when the tape 200 is dragged; due to the small diameter of the glue fixing rod 31, after the glue fixing rod 31 contacts the tape 200, the two are in linear contact, so that the cut 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.

[0075] Please continue to see Figure 1 , 2 , 5 to 14, 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 adjusting rail 34 is provided on the support frame 10. The extension direction of the rod adjusting rail 34 is arranged parallel to the extension direction of the glue pulling rail 21 (i.e., it extends parallel to the second direction D2). The rod mounting seat 32 is slidably arranged on the rod adjusting rail 34; a rod adjusting assembly 35 is arranged 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 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.

[0076] 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.

[0077] See also Figure 1 , 2 , 5 to 14, the lower clamping plate 242 is provided with a glue fixing groove 2421 for the glue fixing rod 31 to pass through, and 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, and the lower clamping mounting portion 2423 is connected to the clamping plate driving member 243, and the glue fixing groove 2421 is located on the lower clamping portion 2422, and 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 slide into the glue fixing groove 2421 to adhere to the lower surface of the tape 200 .

[0078] 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 .

[0079] See also Figure 1 , 2 , 5 to 14, the laminating mechanism 50 is used to attach the cut tape to the battery cell located on the battery cell transfer device. In the present embodiment, the laminating mechanism 50 includes a laminating transverse rail 51, a laminating movable seat 52, a movable seat driving assembly 53 and an adsorption assembly 54. The laminating transverse 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 transverse rail 21. The laminating movable seat 52 is slidably arranged on the laminating transverse 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 attach the tape 200 to the surface of the battery cell. The adsorption assembly 54 is arranged on the laminating movable seat 52.

[0080] See also Figure 1 , 2, 5 to 14, the 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.

[0081] See also Figure 1 , 2 , 5 to 14, 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, and the fitting moving seat 52 is fixedly connected to the moving nut seat 532, and 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.

[0082] 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.

[0083] See also Figure 1 , 2, 5 to 14, the adsorption assembly 54 is arranged on the fitting movable seat 52 in a liftable manner, 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 causes 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.

[0084] 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 .

[0085] See also Figure 1 , 2 5 to 14, 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 that 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.

[0086] Please continue to see Figure 1 , 2, 5 to 14, the upper cutter member 61 has a guide extension portion, and the lower cutter member 62 abuts on the guide extension portion, and the guide extension portion abuts on 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.

[0087] See also Figure 1 , 2 , 5 to 14, a distance adjustment 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 adjustment device 70 includes a distance adjustment base frame 71 fixed on the mounting substrate 101, and the distance adjustment base frame 71 has a distance adjustment space 72 for the support frame 10 to slide. The distance adjustment base frame 71 is provided with a distance adjustment shaft (not shown in the figure), and the two are connected by a thread, and the distance adjustment shaft is connected and fixed to the support frame 10. A waist-shaped distance adjustment hole 73 is provided at the bottom of the support frame 10, and a fixing lock hole (not shown in the figure) corresponding to the distance adjustment hole 73 is provided on the mounting substrate 101. In this way, the relative position between the support frame 10 and the mounting substrate 101 can be adjusted, so as to adapt to batteries with different width dimensions (the width dimension is the dimension in the direction parallel to the first direction D1), thereby improving the practicality of the device.

[0088] See also Figure 1 , 2 , 5, 15 and 16, the release paper separation mechanism 40 provided in this embodiment includes a receiving wheel 41, a receiving wheel driving member 42, a separation guide block 43 and a locking assembly 44 arranged on the support frame 10.

[0089] See also Figure 1 , 2 , 5, 15 and 16, the receiving wheel 41 is rotatably supported at the bottom of the support frame 10 and connected to the receiving wheel driving member 42. In this embodiment, the receiving wheel driving member 42 is but not limited to a motor, and is connected to the receiving wheel 41 through a reducer. It is worth mentioning that when feeding glue, the glue clamping mechanism clamps the free end of the tape 200 and pulls the tape 200 to move to the left (the left direction in the figure). At the same time, the receiving wheel driving member 42 drives the receiving wheel 41 to rotate, so as to pull the release paper 201 in the direction opposite to the pulling direction of the tape 200 (i.e., the right direction in the figure) to move the release paper 201, so that the release paper 201 located on the lower surface of the tape 200 (the lower surface in the figure) is separated from the foam adhesive tape, and the separated release paper 201 is wound on the receiving wheel 41.

[0090] See also Figure 1 , 2, 5, 15 and 16, a separation guide block 43, which has a top portion 431 for abutting against the surface of the release paper 201. In this embodiment, the separation guide block 43 has an inclined surface 432 located on its top surface, and the inclined surface 432 extends from the top portion 431 along the pulling direction of the release paper 201 along the receiving wheel 41 (the right side direction in the figure) and upward (the upper side in the figure). The bottom surface of the separation guide block 43 is roughly parallel to the horizontal plane, and the inclined surface 432 of the separation guide block 43 and the bottom surface of the separation guide block 43 form an angle , the angle ranges from 10° to 30°, and preferably, the angle between the inclined surface 432 of the separation guide block 43 and the bottom surface of the separation guide block 43 is 25°. It should be noted that the top portion 431 has an edge, which is formed by the intersection of the inclined surface 432 of the separation guide block 43 and the bottom surface of the separation guide block 43. That is to say, the smaller the angle between the inclined surface 432 of the separation guide block 43 and the bottom surface of the separation guide block 43, the smaller the resistance to pulling the release paper 201, which is conducive to the separation of the release paper 201 from the tape 200.

[0091] See also Figure 1 , 2 , 5, 15 and 16, the locking assembly 44 is used to clamp the release paper 201 together with the separation guide block 43 and keep the release paper 201 therebetween. In this embodiment, the locking assembly 44 includes a locking disk 441 for abutting against the separation guide block 43 and a locking driving member 442 for driving the locking disk 441 to move up and down. The locking driving member 442 is but not limited to a cylinder and is fixedly installed below the separation guide block 43. Under the drive of the locking driving member 442, the locking disk 441 moves upward (upward in the figure) and presses the release paper 201 against the bottom surface of the separation guide block 43 to limit the movement of the release paper 201. It should be pointed out that when the glue laminating mechanism stops feeding the adhesive tape 200 after pulling the adhesive tape 200 for a preset distance, the locking plate 441 moves upward and presses the release paper 201 against the separation guide block 43. Since the pressing force between the locking plate 441 and the separation guide block 43 is greater than the driving force of the receiving wheel driving component 42, the release paper 201 stops moving; when the glue laminating mechanism pulls the adhesive tape 200 to feed the adhesive tape again, the locking plate 441 moves downward, and the receiving wheel 41 continues to rotate under the drive of the receiving wheel driving component 42 and pulls the release paper 201 to move.

[0092] Specifically, the locking disk 441 has a circular cross-section, and the locking disk 441 is removably connected to the locking drive 442 by fasteners such as screws and bolts. In this way, the locking disks 441 of different sizes can be replaced according to the tapes 200 of different sizes.

[0093] See also Figure 1 , 2, 5, 15 and 16, a guide roller group 12 is provided on the support frame 10, and the guide roller group 12 includes a first guide roller 121 for abutting against the tape 200 and a second guide roller 122 for abutting against the release paper 201, the first guide roller 121 is located above the separation guide block 43, and the second guide roller 122 is arranged between the separation guide block 43 and the receiving wheel 41. In the present embodiment, the number of the first guide rollers 121 is but not limited to two, and the plane formed by the rotation axes of the two first guide rollers 121 is substantially parallel to the inclined surface 432 of the separation guide block 43, and the second guide roller 122 is located below the separation guide block 43.
