[0002] In the production of the winding process of cylindrical lithium-ion batteries, the tape pasting mechanism on the winding machine equipment needs to paste a tape on both the front and back sides at the position of the empty foil area where the electrode sheet is not coated with slurry. Currently, the common tape pasting execution components of the tape pasting mechanism on the winding machine equipment are two upper and lower flat plates, and the tape pasting is achieved by the way of patting with the two upper and lower flat plates.

[0003] This patting method is likely to leave a relatively large number of air bubbles between the tape and the electrode sheet after tape pasting, forming bulging air bubbles on the surface of the electrode sheet, which has a certain impact on the quality of the battery cell and will also affect the yield of subsequent processes.

[0006] In a possible design, the pressing wheel includes:

[0007] A first pressing wheel, which is used to transfer the tape to one side of the electrode sheet;

[0008] A second pressing wheel, which is arranged opposite to the first pressing wheel and is used to transfer the tape to the other side of the electrode sheet.

[0009] In a possible design, the device further includes a back plate, which is used to support the pressing wheel, and a guiding path is formed on the back plate;

[0010] The guiding path includes a tape preparation section and a tape pasting section. The end of the tape preparation section is connected to the start of the tape pasting section. After adsorbing the tape at the start of the tape preparation section, the pressing wheel moves along the tape preparation section to the start of the tape pasting section, and the pressing wheel rotates around its own axis and moves along the tape pasting section to the end of the tape pasting section to transfer the tape to the electrode sheet.

[0011] In a possible design, a guiding hole is formed on the back plate, and the extending direction of the guiding hole is consistent with that of the guiding path. The guiding hole is used for the wheel shaft of the pressing wheel to pass through.

Detailed implementation manners

[0041] The technical solutions of the present application will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0042] The following will be combined with Figures 1 - 6 to describe the tape pasting device provided in the embodiments of the present application.

[0043] Referring to Figure 1 and Figure 2 As shown, in the embodiment provided by the present application, the tape pasting device includes a pressure roller 100. The wheel surface of the pressure roller 100 is used to adsorb the tape. The pressure roller 100 moves along a preset direction while rotating around its own axis to transfer the tape to the wafer. In some specific embodiments, the pressure roller 100 is a cylindrical wheel. An air cavity is formed inside the pressure roller 100. The air cavity is an annular cavity. Air holes 130 are formed on the wheel surface of the pressure roller 100. The air holes 130 are communicated with the air cavity. The air cavity is communicated with a negative pressure machine. A negative pressure cavity is formed inside the air cavity through the negative pressure machine, so that a negative pressure environment is formed on the cylindrical wheel surface. Under the action of the negative pressure, the tape can be adsorbed on the wheel surface of the pressure roller 100.

[0044] Using the technical solutions in the above embodiments, by adsorbing the tape on the wheel surface of the pressure roller 100, the tape can be attached to the wheel surface. By rotating the pressure roller 100 around its own axis and moving along a preset direction at the same time, the tape attached to the wheel surface can contact and adhere to the surface of the wafer during the rotation of the pressure roller 100, so as to smoothly transfer the tape to the wafer. The present application uses the pressure roller 100 to roll the wafer to realize the rolling paste of the tape on the wafer, and can timely roll out the gas between the tape and the wafer during the rolling process, so as to effectively prevent a large number of bubbles from remaining between the wafer and the tape after pasting, which is beneficial to improving the quality of the battery cell and the yield of subsequent process products.

[0045] Referring to Figure 1, Figure 2 As shown, in some embodiments provided by the present application, the pressing wheel includes a first pressing wheel 110 and a second pressing wheel 120. The first pressing wheel 110 is used to transfer the tape to one side of the electrode sheet; the second pressing wheel 120 is disposed opposite to the first pressing wheel 110, and the second pressing wheel 120 is used to transfer the tape to the other side of the electrode sheet. Specifically, the first pressing wheel 110 is located above the electrode sheet, and the adhesive surface of the tape faces away from the wheel surface of the first pressing wheel 110. The first pressing wheel 110 rolls on the upper end surface of the electrode sheet to make the tape adhere to the upper end surface of the electrode sheet; the second pressing wheel 120 is located below the electrode sheet, and the adhesive surface of the tape faces away from the wheel surface of the second pressing wheel 120. The second pressing wheel 120 rolls on the lower end surface of the electrode sheet to make the tape adhere to the lower end surface of the electrode sheet. In this way, by making the first pressing wheel 110 and the second pressing wheel 120 roll on the upper and lower end surfaces of the electrode sheet respectively, simultaneous gluing of both sides of the tape is achieved; and since the first pressing wheel 110 and the second pressing wheel 120 press against each other, the force on the electrode sheet can be offset, preventing the electrode sheet from being torn during the rolling process and improving the quality of the electrode sheet after gluing.

[0046] Referring to Figure 1 , Figure 2 As shown, in some embodiments provided by the present application, the device further includes a back plate 200. The back plate 200 is used to support the pressing wheel 100, and a guiding path 210 is formed on the back plate 200; the guiding path 210 includes a tape preparation section 211 and a tape pasting section 212. The end of the tape preparation section 211 is connected to the beginning of the tape pasting section 212. The pressing wheel 100 adsorbs the tape at the beginning of the tape preparation section 211 and moves along the tape preparation section 211 to the beginning of the tape pasting section 212. The pressing wheel 100 rotates around its own axis at the beginning of the tape pasting section 212 and moves along the tape pasting section 212 to the end of the tape pasting section 212 to transfer the tape to the electrode sheet. Specifically, the tape pasting section 212 is a straight line segment parallel to the surface of the electrode sheet, and the distance between the tape pasting section 212 and the surface of the electrode sheet is approximately equal to the radius of the pressing wheel 100. In this way, when the pressing wheel 100 moves linearly along the tape pasting section 212 and rotates around its own axis in the tape pasting section 212, the tape on the wheel surface of the pressing wheel 100 can be adhered to the surface of the electrode sheet.

[0047] It should be noted that the pole piece is in a moving and transporting state before and after gluing. During the gluing process, the pole piece is in a short-term stop state. Since the distance between the pressing wheel 100 and the pole piece in the gluing section 212 is small, the preparation of the glue by the pressing wheel 100 in the gluing section 212 may affect the transportation of the pole piece. Therefore, by providing a glue preparation section 211 connected to each other at the input end of the gluing section 212, the pressing wheel 100 can pre-prepare the glue in the glue preparation section 211 (the tape is adsorbed on the wheel surface). Specifically, the shape of the glue preparation section 211 can be designed according to the actual situation. For example, the glue preparation section 211 is a straight section, an arc section or other shapes. By providing the glue preparation section 211, the pressing wheel 100 can complete the glue preparation in the glue preparation section 211, and then move to the gluing section 212 through the glue preparation section 211 to successfully complete the gluing.

[0048] Referring to Figure 3 、 Figure 5 As shown, in some embodiments provided by the present application, a guiding hole 220 is formed on the back plate 200. The extending direction of the guiding hole 220 is the same as the guiding path 210, and the guiding hole 220 is used for the wheel shaft of the pressing wheel 100 to pass through. Specifically, the front section of the guiding hole 220 is a curved section, that is, the glue preparation section 211; the rear section of the guiding hole 220 is a straight section, that is, the gluing section 212; the pressing wheel completes the glue preparation at the first end of the guiding hole 220, passes through the curved section and reaches the straight section to perform gluing. In some of these specific embodiments, there are two guiding holes 220. The wheel shafts of the first pressing wheel 110 and the second pressing wheel 120 are respectively inserted into the corresponding guiding holes 220, and the wheel shafts of the first pressing wheel 110 and the second pressing wheel 120 move along the corresponding guiding holes 220. In some specific embodiments, an avoidance hole 230 is formed on the back plate 200, and the avoidance hole 230 is used for the pole piece to pass through. Specifically, the avoidance hole 230 is arranged between the two guiding holes 220, and the avoidance hole 230 is a long hole parallel to the guiding hole 220. In this way, when the first pressing wheel 110 and the second pressing wheel 120 move in the corresponding guiding holes 220 respectively, the glue preparation can be completed at the same time and the upper and lower end faces of the pole piece can be glued at the same time. In some of these specific embodiments, one end of the avoidance hole 230 opens outward, which is beneficial to inserting the pole piece into the avoidance hole 230.

[0049] Referring to Figure 4 、 Figure 6As shown, in some embodiments provided by the present application, the device further includes a moving plate 300, a first driver 410, and a second driver 420. The moving plate 300 is disposed on the side of the back plate 200 away from the pressing wheel 100. A rectangular hole 310 is formed in the moving plate 300. The length direction of the rectangular hole 310 is parallel to the height direction of the back plate 200, and the rectangular hole 310 is used for the wheel shaft to pass through. The first driver 410 is disposed on the moving plate 300 and is connected to the wheel shaft for driving the pressing wheel 100 to rotate about its own axis. The first driver 410 can be a servo motor. The second driver 420 is disposed on the back plate 200 and is connected to the moving plate 300 for driving the moving plate 300 to move along the length direction of the back plate 200. The second driver 420 can be a servo motor, a cylinder, a hydraulic cylinder, or an electric push rod. In some specific embodiments, the device further includes a first guide rail 510, a first slider 520, a second guide rail 530, and a second slider 540. The first guide rail 510 is disposed on the back plate 200, and the length direction of the first guide rail 510 is parallel to the length direction of the back plate 200. The first slider 520 is disposed on the side of the moving plate 300 close to the back plate 200 and is slidably engaged with the first guide rail 510. The second guide rail 530 is disposed on the side of the moving plate 300 away from the back plate 200, and the length direction of the second guide rail 530 is parallel to the height direction of the back plate 200. The second slider 540 is mounted on the first driver 410 and is slidably engaged with the second guide rail 530. In this way, when the second driver 420 pushes the moving seat to move horizontally (move along the length direction of the back plate 200), the wheel shaft of the pressing wheel 100 is guided by the guiding hole 220 to cause a longitudinal displacement relative to the moving plate 300, that is, the wheel shaft of the pressing wheel 100 moves up and down in the rectangular hole 310, so that the wheel shaft of the pressing wheel 100 can move along the guiding hole 220. In some specific examples, the moving plate 300, the first driver 410, and the second driver 420 are respectively two, corresponding to the first pressing wheel 110 and the second pressing wheel 120 respectively, so that the first pressing wheel 110 and the second pressing wheel 120 move along the corresponding guiding holes 220.

[0050] Refer to Figure 1As shown, in some embodiments provided by the present application, the device further includes a tape reel 610, a first jaw 710, a second jaw 720, and a cutter 800. The tape reel 610 is arranged on the back plate 200 for sleeving a tape roll. The first jaw 710 and the second jaw 720 are respectively used for clamping the tape, and the second jaw 720 can clamp the end of the tape roll and move it in a direction away from the second jaw 720. The cutter 800 is arranged on the side of the first jaw 710 close to the second jaw 720 for cutting the tape. Specifically, the first jaw 710 and the second jaw 720 are pneumatic jaws for clamping the upper and lower end faces of the clamping piece. In some specific embodiments, it further includes a third driver 430. The third driver 430 is a servo motor or an electric push rod or a cylinder or a hydraulic cylinder. The third driver 430 is connected to the second jaw 720 and can drive the second jaw 720 to move along the length direction of the back plate 200 to approach or move away from the second jaw 720, so as to pull out a certain length of the tape from the tape roll. In some specific embodiments, it further includes a fourth driver 440. The fourth driver 440 is a servo motor or an electric push rod or a cylinder or a hydraulic cylinder. The fourth driver 440 is fixed on the back plate 200 through a mounting seat. The fourth driver 440 is connected to the cutter 800 for driving the cutter 800 to move along the height direction of the back plate 200 to cut the pulled tape. In some of these specific embodiments, a plurality of guide rollers 620 are further arranged between the second jaw 720 and the tape reel 610, and the tape is guided to the first jaw 710 by passing the tape around the guide rollers 620 in sequence. In some of these specific embodiments, the tape reel 610, the first jaw 710, the second jaw 720, and the cutter 800 are respectively two, and are respectively used for pulling and cutting the tape on the first pressing wheel 110 and the second pressing wheel 120. In some of these specific embodiments, the two second jaws 720 are installed on the same jaw seat 730. The jaw seat 730 is U-shaped. In this way, the jaw seat 730 can drive the two second jaws to move laterally at the same time. At the same time, when the jaw seat 730 moves laterally, it will not be blocked by the pole piece passing through the avoidance hole 230.

[0051] The working process of the tape pasting device of the present application:

[0052] The tape roll is sleeved on the tape reel 610, and the end of the tape passes around the guide rollers 620 in sequence, and the first jaw 710 clamps the end of the tape;

[0053] The third driver 430 drives the second jaw 720 to approach the first jaw 710 and clamps the end of the tape. After the first jaw 710 releases the tape, the third driver 430 drives the second jaw 720 to move away from the first jaw 710, pulling out a certain length of the tape from the tape roll;

[0054] The fourth driver 440 drives the cutter 800 to move towards the tape to cut the pulled tape, and the second jaw 720 releases the tape;

[0055] Under the negative pressure on the surface of the pressure roller 100, the cut tape is adsorbed onto the surface of the pressure roller 100;

[0056] The first driver 410 drives the pressure roller 100 to rotate by a certain angle, so that one end of the tape is exactly located at the lowermost end of the first pressure roller 110 or the uppermost end of the second pressure roller 120;

[0057] The second driver 420 drives the pressure roller 100 to move along the guide hole 220. After the pressure roller 100 reaches the tape sticking section 212, the first driver 410 drives the pressure roller 100 to rotate again, so that the pressure roller 100 rolls on the surface of the pole piece, and the tape on the pressure roller 100 adheres to the surface of the pole piece.
