[0045] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0046] In this application, unless otherwise clearly defined and limited, the terms "mounted", "connected", "coupled", "fixed", etc. shall be construed broadly.

[0048] During the manufacturing process of the battery cell, it is usually necessary to tightly wind the electrode sheets (cathode sheet, anode sheet) and the separator. Since the electrode sheets and the separator have a certain elasticity in this application, the ends of the wound core are prone to looseness, which has an adverse effect on subsequent assembly and processing.

[0049] Based on the existing problems, this application provides a cutting and pasting device, including a glue supply assembly 100, a glue feeding assembly 200, a top-pasting structure 300, and a glue cutting structure 400; the glue supply assembly 100 provides the tape for pasting, the glue feeding assembly 200 is located in the conveying downstream direction of the glue supply assembly 100, the glue feeding assembly 200 is used for clamping and pulling the tape of the glue supply assembly 100 to move, the top-pasting structure 300 is located on one side of the pulling direction of the glue feeding assembly 200, the top-pasting structure 300 is used for pressing the tape pulled by the glue feeding assembly 200, and the glue cutting structure 400 is located on one side of the pulling direction of the glue feeding assembly 200, and the glue cutting structure 400 is used for cutting the tape pulled and moved by the glue feeding assembly 200.

[0050] Refer to Figure 1As shown in the figure, in this application, the tape from the glue supply assembly 100 is stretched and pulled to the outer surface position of the core body at the tape sticking position 800 by the glue feeding assembly 200, and then the tape is fixed-pressure pasted to the outer surface of the core body through the top sticking structure 300. Next, the tape can be cut off by the tape cutting structure 400. With the rotation of the core body at the tape sticking position 800 and the pressing action of the top sticking structure 300, the cut tape is closely attached to the outer surface of the core body, so as to paste the end of the core body, prevent the core body from loosening, and facilitate the subsequent assembly operation of the core body.

[0051] The glue supply assembly 100 includes a tape roll 110, a plurality of guide rollers 120 and a buffer structure 130. The guide rollers 120 are used to guide the tape from the tape roll 110; the buffer structure 130 is located in the tape conveying path from the tape roll 110, and the buffer structure 130 is used to buffer the tape from the tape roll 110.

[0052] Refer to Figure 3 As shown in the figure, first, the tape roll 110 is provided with a wound tape. In order to smoothly convey the tape from the tape roll 110 to the position of the glue feeding assembly 200, a plurality of guide rollers 120 are required to cooperate to guide the tape and change its direction. Moreover, in order to keep the tape in a tensioned state and not separated from the guide rollers 120, the buffer structure 130 is required to buffer the slack tape and achieve tension.

[0053] Specifically, the buffer structure 130 includes a mounting member 131. A guiding member 132 is fixedly installed on the upper side of the mounting member 131. A sliding member 133 is slidably arranged on the guiding member 132. At least one moving roller 134 is arranged on the side of the sliding member 133. A first linear driving member 135 is also fixedly installed on the mounting member 131. The driving end of the first linear driving member 135 is connected to the sliding member 133. An expansion member 136 is sleeved on the outer surface of the guiding member 132. The expansion member 136 is located between the mounting member 131 and the sliding member 133.

[0054] Refer to Figure 3 and Figure 4 As shown in the figure, in this embodiment, there are two mounting members 131. The two mounting members 131 are connected by the guiding member 132, and the guiding member 132 not only plays a role in guiding the sliding member 133 but also plays a role in connecting the two mounting members 131.

[0055] Specifically, the moving roller 134 is installed on the sliding member 133. A first linear driving member 135 is installed on one of the mounting members 131. The driving end of the first linear driving member 135 is connected to the sliding member 133. Therefore, when the first linear driving member 135 is started, it can drive the sliding member 133 to move under the guidance of the guiding member 132, and then drive the moving roller 134 to move. It should be noted here that when the tape passes through each guide roller 120, it will also wind around the moving roller 134. The movement of the moving roller 134 drives the tape passing through it to move, realizing the tensioning and buffering of the tape in a slack state.

[0056] Continue to refer to Figure 4 As shown, in order to make the sliding member 133 move more smoothly, a telescopic member 136 can be provided on the guiding member 132 to achieve buffering.

[0057] Exemplarily, the first linear driving member 135 can be a cylinder, an oil cylinder, a motor screw linear module, a gear rack linear module, etc. That is, as long as it can realize the linear driving to drive the sliding member 133 to move, any component or structure can be used. In this embodiment, the first linear driving member 135 is specifically selected as a cylinder. When other types or components are selected, the structure of this buffer structure 130 can be designed and changed according to the actual situation.

[0058] The tape feeding assembly 200 includes a two-axis driving module 210. A moving plate 220 is arranged at the moving end of the two-axis driving module 210. A fixed clamping plate 230 is fixedly installed on the moving plate 220, and a moving clamping plate 240 is hingedly installed. A third linear driving member 250 is also installed on the moving plate 220. The third linear driving member 250 is hinged to the moving clamping plate 240. The third linear driving member 250 is used to drive the moving clamping plate 240 to rotate and move towards the fixed clamping plate 230 to clamp the tape located between the fixed clamping plate 230 and the moving clamping plate 240.

[0059] Refer to Figure 5 and Figure 6As shown, in order to realize the traction movement of the tape, the tape needs to be clamped. For this purpose, the tape is clamped through the cooperation of a fixed clamping plate 230 fixed on the tape feeding assembly 200, a movable clamping plate 240 rotatably installed on the moving plate 220, and a third linear driving member 250. The third linear driving member 250 is hingedly installed on the moving plate 220, and the driving end of the third linear driving member 250 is hinged to the movable clamping plate 240. Specifically, in the initial state, the third linear driving member 250 drives the movable clamping plate 240 to rotate, so that the movable clamping plate 240 is separated from the fixed clamping plate 230, and the clamping state of the tape is released. When traction movement is required, only the third linear driving member 250 needs to drive the movable clamping plate 240 to rotate towards the fixed clamping plate 230, clamping and fixing the tape located between the fixed clamping plate 230 and the movable clamping plate 240. When movement is required, the two-axis driving module 210 drives the clamped tape to move towards the tape sticking position 800. After moving a certain distance, the clamping of the tape can be released, and the two-axis driving module 210 can be restored to the initial state to complete the tape feeding action.

[0060] Exemplarily, the two-axis driving module 210 can realize movement in two directions, namely horizontally and vertically. Specifically, the structure for realizing movement in two directions can be formed by combining a motor lead screw module, a motor synchronous belt module, a linear motor module, a gear rack module, a cylinder, etc. In order to achieve precise positioning, the motor lead screw module is used for horizontal movement, and the cylinder is used for vertical movement. For details, see Figure 5 shown.

[0061] A guide rod 260 is installed on the side of the moving plate 220, and the outer surface of the guide rod 260 is flush with the clamping surface of the fixed clamping plate 230.

[0062] Continue to refer to Figure 5 As shown, in order to enable the tape to smoothly enter between the fixed clamping plate 230 and the movable clamping plate 240, a guide rod 260 can be provided on the moving plate 220, and the tape is guided between the fixed clamping plate 230 and the movable clamping plate 240 through the guiding of the guide rod 260.

[0063] The top sticking structure 300 includes a fourth linear driving member 310, and the driving end of the fourth linear driving member 310 is fixedly installed with a first fixing frame 320, and a top wheel 330 is rotatably installed on the first fixing frame 320.

[0064] The tape cutting structure 400 includes a fifth linear driving member 410, and the driving end of the fifth linear driving member 410 is fixedly installed with a second fixing frame 420, and a first cutter 430 is fixedly installed on the second fixing frame 420.

[0065] Refer to Figure 7As shown, in order to separate the adhered tape from the tape from the tape roll 110, the two need to be cut. Specifically, the fifth linear driving member 410 drives the first cutter 430 located on the second fixing bracket 420 to move towards the tape, and the tape is cut by the first cutter 430.

[0066] Continue to refer to Figure 7 As shown, the fourth linear driving member 310 drives the top wheel 330 located on the first fixing bracket 320 to apply a constant pressure to the core at the tape sticking position 800. At this time, the tape is located between the top wheel 330 and the surface of the core at the tape sticking position 800. At this time, the tape to be adhered is separated from the tape from the tape roll 110. As the tape sticking position 800 rotates, the tape to be adhered is adhered to the outer surface of the core, thereby preventing the core from loosening.

[0067] Refer to Figure 1 It can be seen that when cutting the tape, in order to prevent the first cutter 430 from interfering with the fixed clamping plate 230 and the movable clamping plate 240, it is necessary to drive the fixed clamping plate 230 and the movable clamping plate 240 away from the first cutter 430 through the two-axis driving module 210. Only after moving away can the avoidance cutting be achieved. In order to prevent the tape from being continuously pulled towards the tape sticking position 800 at this time, it is necessary to clamp the tape again through the fixed clamping plate 230 and the movable clamping plate 240 at this time. And in order to further fix the tape from being pulled, the tape is fixed by the pressing structure 140. Specifically, the second linear driving member 141 drives the pressing block 142 to move towards one of the guide rollers 120, and the tape is clamped between the pressing block 142 and the guide roller 120 until the tape cutting is completed.

[0068] This application also provides a battery core winding device, including a tape sticking position 800, a pressing structure 500, a winding position 900, a cutting structure 600 and a fixing plate 700. The tape sticking position 800 has a core roll. The cutting and sticking device described in any one of the above applies tape to the core roll. The pressing structure 500 abuts against the core roll. The pressing structure 500 abuts against the outer surface of the core roll to prevent the core roll from spreading. The cutting structure 600 is used to cut the diaphragm at the position of the winding position 900. The pressing structure 500 and the cutting structure 600 are both installed on the fixing plate 700.

[0069] Refer to Figure 1 and Figure 2 As shown, when applying tape, the pressing structure 500 can be abutted against the core at the tape sticking position 800, and the core is slightly pressed by the pressing structure 500 to prevent it from loosening. The winding position 900 is the working position for winding the core. Specifically, after winding is completed, the diaphragm is cut by the cutting structure 600.

[0070] The pressing structure 500 includes a first sliding plate 510 slidably mounted on the fixing plate 700 and a sixth linear driving member 530 fixedly mounted on the fixing plate 700. A pressing wheel 520 is mounted at the end of the first sliding plate 510 facing the glue - applying position 800.

[0071] Refer to Figure 8 As shown, the first sliding plate 510 is slidably mounted on the fixing plate 700, specifically on the bottom surface of the fixing plate 700. When pressing is required, the sixth linear driving member 530 drives the first sliding plate 510 to move, thereby driving the pressing wheel 520 to move towards the glue - applying position 800 and making the pressing wheel 520 contact the surface of the core to achieve pressing.

[0072] The cutting structure 600 includes a second sliding plate 610 slidably mounted on the fixing plate 700 and a rotary driving member 630 fixedly mounted on the fixing plate 700. A rotating wheel 640 is mounted at the rotating end of the rotary driving member 630. A connecting rod 650 is mounted on the rotating wheel 640, and the other end of the connecting rod 650 is connected to the second sliding plate 610. A second cutting knife 620 is mounted at the end of the second sliding plate 610 facing the fixing plate 700.

[0073] Refer to Figure 9 As shown, after the core is wound at the winding position 900, the diaphragm between the cathode sheet and the anode sheet can be cut by the second cutting knife 620. Specifically, in this application, a crank - connecting - rod structure is mainly used to intermittently drive the second cutting knife 620 to cut the diaphragm. Specifically, the second sliding plate 610 is slidably mounted on the fixing plate 700. Further, the second sliding plate 610 is slidably mounted on the upper surface of the fixing plate 700. Then, the rotary driving member 630 drives the rotating wheel 640, and under the transmission of the connecting rod 650, drives the second sliding plate 610 to intermittently move towards and away from the winding position 900, thereby realizing cutting the diaphragm by the second cutting knife 620.

[0074] This core winding device also discloses a discharging position 1000. The wound and glued core is discharged at the discharging position 1000. Specifically, structures or methods such as mechanical grippers can be used for discharging.
