[0040] When manufacturing the battery pole piece, the coating material needs to be coated on the metal foil, and then dried to form a coating area; since the structure of the coating area after drying is relatively loose, it also needs to be flattened and compacted by rolling. It is found in production that, since the thickness of the coating area of the pole piece is large, and the blank foil area used to form the lug does not need to be coated and has a small thickness, in the rolling and conveying process, the pole piece is prone to wrinkles due to uneven stress.

[0041] In view of the problem that the lug is prone to wrinkles, the force difference between the coating area and the blank foil area is often reduced by manually attaching adhesive tape on the roller or pressing roller to reduce the risk of wrinkles. However, since the manual attachment method is affected by individual operation differences, the attachment precision consistency is poor, which cannot meet the requirements.

[0042] In the related art, an adhesive tape attaching mechanism is used to attach the adhesive tape. The film is installed on the roller shaft of the adhesive tape attaching structure, and the film is fixed by the limiting structure installed at both ends of the roller shaft to avoid falling off, but when replacing the film, any limiting structure needs to be removed from the roller shaft, and after disassembly and assembly, the limiting structure is connected with the roller shaft. The whole disassembly and assembly process is relatively cumbersome.

[0043] To solve the above problems, the first aspect embodiment of the application provides an adhesive tape attaching mechanism, which is used to be arranged on a mounting base. It should be noted that the adhesive tape attaching mechanism is applied to a pole piece rolling device for attaching adhesive tape to the roller shaft or the pole piece. The adhesive tape can be Teflon, blue glue, etc. The mounting base can be a part of the rolling device, such as a support rod arranged above the roller shaft, a fixed roller, etc. The adhesive tape attaching mechanism can be installed on the support rod and bond the joint end of the film to the roller shaft. When the roller shaft rotates at a low speed, the film is wound on the roller shaft. The mounting base can also be a structure independent of the pole piece rolling device, such as a wall, a mounting rack, etc., for fixing and mounting the adhesive tape attaching mechanism and conveying the adhesive tape to the roller shaft.

[0044] For the convenience of subsequent understanding, the roller shaft appearing in the present application is defined first, and the roller shaft described in the present application includes an over roller and a pressure roller. The over roller is usually used for the continuous and stable transmission of the pole piece tape on the production line. By adjusting the rotating speed of the over roller and setting the position, the precise control of the tension of the pole piece tape can be realized, so as to avoid the adverse effects caused by the too large or too small tension of the tape during the transmission process. The pressure roller often appears in pairs. The pole piece passes through the gap between the two pressure rollers to realize the compaction of the pole piece, so as to improve the density of the pole piece, improve the thickness consistency, enhance the adhesion strength of the active material and the current collector, and the like. It can be understood that the over roller can be arranged before the pressure roller in the transmission sequence of the pole piece, and the over roller can also be arranged after the pressure roller.

[0045] During the transmission of the pole piece, due to the thickness difference between the empty foil area and the coated area, the friction force between the empty foil area and the over roller is smaller than the friction force between the coated area and the over roller, thereby causing the force difference between the empty foil area and the coated area. Therefore, during the transmission of the pole piece, adhesive tape can be attached to the empty foil area of the pole piece, so as to compensate for the thickness difference between the empty foil area and the coated area, so as to reduce the friction force difference between the empty foil area and the coated area. Alternatively, adhesive tape can also be attached to the position corresponding to the empty foil area of the over roller before the transmission of the pole piece to form a flange on the over roller, so that when the pole piece passes through, the adhesive tape can support the empty foil area and repair it, so as to improve the wrinkles, stress lines and the like on the empty foil area of the pole piece. In addition, adhesive tape can also be attached to the position corresponding to the empty foil area of the pressure roller to form a flange, so as to reduce the force difference between the coated area and the empty foil area, so as to reduce the probability of wrinkle generation.

[0046] The adhesive tape attaching mechanism of the present application can be applied to any of the above-mentioned scenarios that require the attachment of adhesive tape, and can realize the automatic unwinding of the adhesive tape, thereby obtaining better attachment consistency. It can be understood that the adhesive tape is wound layer by layer on the core to form a circular ring structure. When the adhesive tape is needed, the adhesive tape needs to be pulled from the joint end of the adhesive tape roll to make the adhesive tape roll rotate and release the adhesive tape. For this kind of adhesive tape roll structure, the adhesive tape attaching mechanism of the present application includes a connecting assembly 100 and a mounting assembly 200. The connecting assembly 100 is used to connect with the mounting base described above, and the mounting assembly 200 is rotationally connected with the connecting assembly 100, and the mounting assembly 200 is used to mount the adhesive tape roll. The mounting assembly 200 includes a main body 210, which is a columnar structure and can be penetrated into the core of the adhesive tape roll, so that the adhesive tape roll is sleeved on the main body 210 and connected with the main body 210.

[0047] In order to facilitate the disassembly of the adhesive tape roll, the adhesive tape attaching mechanism of the present application is provided with a limiting protrusion 212 on the main body 210. Specifically, as shown in Figure 1 It is to be noted that, Figure 1The limiting protrusion 212 shown is retracted into the mounting hole 211. The limiting protrusion 212 is arranged through the mounting hole 211 and is elastically connected with the main body 210. For example, the mounting hole 211 can be a stepped hole, and the limiting protrusion 212 can include a protruding part and an elastic part. The protruding part is a columnar structure, and one end of the elastic part is connected with the protruding part, and the other end is in abutment with the stepped surface of the stepped hole, so that when the protruding part is pressed to move towards the stepped surface, the elastic part is forced to compress and deform.

[0048] It can be understood that the limiting protrusion 212 has a second state of being pressed to retract and a first state of not being pressed. In the first state, the limiting protrusion 212 protrudes from the outer circumferential surface of the main body 210, and in the second state, the limiting protrusion 212 is retracted towards the mounting hole 211. Compared with the limiting protrusion 212 in the first state, the limiting protrusion 212 in the second state is at least partially retracted into the mounting hole 211, that is, the protruding length of the limiting protrusion 212 in the second state is less than that in the first state. When the film roll is sleeved on the main body 210, the limiting protrusion 212 is in the second state and is in abutment with the film roll, and when the film roll is detached from the main body 210, the limiting protrusion 212 is switched from the second state to the first state.

[0049] It should be noted that the limiting protrusion 212 is used to abut against the inner wall of the core of the film roll, and the displacement of the film roll is limited by the static friction between the limiting protrusion 212 and the film roll, so that the position of the film roll on the main body 210 is fixed, and the film roll is prevented from moving during unwinding. Therefore, in the first state, the distance from the free end of the limiting protrusion 212 to the rotation center should be greater than the hole diameter of the core inner hole. When the film roll is mounted on the main body 210, the limiting protrusion 212 needs to be pressed to retract until the core can be sleeved on the main body 210, and then the limiting protrusion 212 is released to extend under the action of the elastic force and abut against the hole wall of the core, so that the limiting protrusion 212 remains in the second state and supports the core outward. On the one hand, the limiting protrusion 212 and the core between the static friction force plays a role in limiting the movement of the film roll, and on the other hand, it also improves the adaptability of the film attaching mechanism, so that the film attaching mechanism can be applied to film rolls of various sizes and specifications.

[0050] Based on the above, when the film roll needs to be removed, the limiting protrusion 212 only needs to be pressed to retract, so that the limiting protrusion 212 is separated from the hole wall of the core of the film roll, and the film roll can be removed from the main body 210. Similarly, when the film roll is installed, the limiting protrusion 212 is pressed to retract, and after the film roll is installed in place, the limiting protrusion 212 is released to elastically reset, so that the free end of the limiting protrusion 212 abuts against the hole wall of the core, thereby fixing the main body 210 and the core while limiting the displacement of the core on the main body 210. The film roll can be disassembled without disassembling other parts, which is convenient and efficient.

[0051] In some embodiments, the mounting assembly of this application further includes a limiting member 220, which protrudes from the outer peripheral surface of the main body 210. When the film roll is mounted onto the main body 210, the film roll moves axially relative to the main body 210 until the end face of the film roll abuts against the protruding limiting member 220, thereby defining the mounting position of the film roll on the main body 210. It is understood that defining the mounting position of the film roll by the position of the limiting member 220 serves two purposes: firstly, it improves the adhesion accuracy of the tape in the empty foil area by using a unified positioning reference; secondly, it helps to ensure the consistency of the film roll position before and after film roll replacement.

[0052] It should be noted that the limiting member 220 can be a protruding structure manufactured independently of the main body 210, such as a pin or limiting post set on the outer peripheral surface of the main body 210, or it can be a limiting block integrally formed with the main body 210 and formed on the outer peripheral surface of the main body 210, or it can be like... Figure 2 The first main body portion 221 shown is integrally formed with the main body 210 and is formed at one end of the main body 210, as shown in the figure. Figures 2 to 4 In the embodiment shown, the outer diameter of the first main body 221 is larger than the outer diameter of the main body 210, so that the first main body 221 protrudes from the outer peripheral surface of the main body 210, thereby enabling the end face of the first main body 221 along the rotation axis to abut against the film.

[0053] Furthermore, the limiting member 220 also includes a washer 222 that is detachably connected to the main body 210, such as... Figure 1 As shown, the washer 222 is fitted onto the main body 210, and its inner diameter is smaller than the outer diameter of the first main body 221. After being fitted onto the main body 210, it is located on the side of the first main body 221 that is used to abut against the film. When the film is installed onto the main body 210, the film abuts against the first main body 221 through the washer 222. More specifically, the end face of the film abuts against the washer 222, and the washer 222 abuts against the first main body 221, thereby adjusting the installation position of the film on the main body 210 through the washer 222.

[0054] It is understandable that the edge of the coating area of ​​the electrode is set at a certain angle to the current collector; that is, along the thickness direction and away from the current collector, the width of the coating area gradually decreases, forming a trapezoidal shape. Therefore, when applying tape to the roller shaft, to adapt to the angle at the edge of the coating area, in actual operation, the tape application position is often adjusted to form a stepped flange structure to match the angle at the edge of the coating area. Therefore, the installation position of the tape roll on the main body 210 needs to be changed during the tape application process.

[0055] Specifically, the gasket 222 of the adhesive mechanism comprises gaskets 222 of various thickness dimensions, and each gasket 222 comprises at least one. For example, as shown in the embodiment, Figure 1 In the embodiment shown, a 1mm-thick gasket 222 and a 2mm-thick gasket 222 are installed on the main body 210, so that the film position is translated by 3mm. It can be understood that, in order to form the flange with a stepped structure, the gasket 222 can not be installed first, and after the base of the flange is wound, a 1mm gasket 222 is added, and then a 1mm gasket 222 is added after the flange with a certain thickness is wound, and so on to form the flange with a stepped structure. It can be understood that the specific size and addition sequence of the gasket 222 can be determined according to the specific requirements of the flange.

[0056] The gasket 222 is beneficial to accurately control the installation position of the film, realizes the standardized and modularized adjustment of the film installation position, improves the accuracy of the film position adjustment, and since the operator only needs to add or reduce the gasket 222, the installation is simple and fast, and the work efficiency of adjusting the film position is greatly improved.

[0057] Further, as shown in the embodiment, Figure 5 It can be understood that the gasket 222 is a ring structure, and the inner ring of the gasket 222 is provided with a relief groove 223 for avoiding the limiting protrusion 212 in the first state, so that the gasket 222 can not be interfered by the limiting protrusion 212 when being installed on the main body 210. Specifically, the projection of the limiting member 220 on the axial direction of the main body 210, the relief groove 223 is provided corresponding to the limiting protrusion 212.

[0058] Further, the main body 210 comprises a plurality of second main body portions 214 arranged at intervals, and a weight-reducing groove 213 is defined between adjacent second main body portions 214. The weight-reducing groove 213 can be a square groove, or an arc-shaped groove as shown in the embodiment, Figure 4 Each weight-reducing groove 213 is arranged along the circumferential direction of the main body 210, and more specifically, each weight-reducing groove 213 is uniformly distributed along the circumferential direction of the main body 210. For example, in the embodiment shown, Figure 4 The main body 210 is provided with three weight-reducing grooves 213, and adjacent weight-reducing grooves 213 are arranged at an angle of 120°, and adjacent second main body portions 214 are also arranged at an angle of 120°. It should be noted that the mounting hole 211 is arranged on the second main body portion 214, so that the limiting protrusion 212 can be arranged protruding from the surface of the second main body portion 214.

[0059] In addition, the main body 210 further comprises a plurality of groups of mounting holes 211 and a plurality of limiting protrusions 212. Each group of mounting holes 211 comprises a plurality of mounting holes 211 arranged along the axial direction of the main body 210, so that the adhesive attaching mechanism can be adapted to a plurality of width specifications of the film. Adjacent two groups of mounting holes 211 are arranged along the circumferential direction of the main body 210, and each mounting hole 211 is provided with a limiting protrusion 212. By controlling the protruding length of each group of limiting protrusions 212 in the second state, the axis of the film can be kept consistent with the rotation axis of the main body 210, so as to avoid the eccentric rotation of the film causing the pulling force on the polar plate to be large or small.

[0060] In combination with the weight-reducing grooves 213 and the second main body portion 214 distributed on the main body 210 in the foregoing embodiments, each group of mounting holes 211 is arranged on the second main body portion 214, as shown in Figure 3 The mounting holes 211 extend from the second main body portion 214 along the radial direction of the main body 210 and penetrate to the groove bottom of the weight-reducing groove 213. It can be understood that the mounting holes 211 are designed as through holes, which is beneficial to processing and the installation of the limiting protrusions 212.

[0061] In some embodiments, the connecting assembly 100 can be a plug-in structure, a clamping structure, etc., which can cooperate with the plug-in structure or the clamping structure on the mounting base to achieve the installation of the adhesive attaching mechanism, or the connecting assembly 100 can also be a threaded connection structure, which can be connected with the threaded hole on the mounting base. As shown in Figure 1 and Figure 6 In the embodiments shown in Figure 1 and Figure 6 , the connecting assembly 100 comprises a first connecting piece 110 and a second connecting piece 120, and the first connecting piece 110 and the second connecting piece 120 are connected with each other. The first connecting piece 110 comprises a first clamping segment 111 and a first connecting segment 112 connected with the first clamping segment 111, and the second connecting piece 120 comprises a second clamping segment 121 and a second connecting segment 122 connected with the second clamping segment 121. The first clamping segment 111 and the second clamping segment 121 are both semicircular, and the openings thereof are oppositely arranged. When the first connecting segment 112 and the second connecting segment 122 are connected, the openings of the first clamping segment 111 and the second clamping segment 121 are combined, so as to define a tightening portion surrounded by the first clamping segment 111 and the second clamping segment 121. It can be understood that the tightening portion is used for being sleeved on the mounting base and clamped thereon, so as to achieve the installation of the adhesive attaching mechanism.

[0062] In the embodiments shown in Figure 1 and Figure 6 , the connecting assembly 100 comprises a locking piece 130, which is arranged in one of the first connecting segment 112 and the second connecting segment 122 and connected with the other one, for example, referring to Figure 1 and Figure 6As shown, a through hole is formed on the first connecting segment 112, a threaded hole is formed on the second connecting segment 122, the locking member 130 is arranged in the through hole and connected with the threaded hole of the second connecting segment 122, so that when the locking member 130 is rotated, the connection tightness between the first connecting segment 112 and the second connecting segment 122 can be adjusted to adjust the tightness of the clamping part. Figure 1 As shown, the length of the first connecting segment 112 is longer than the length of the second connecting segment 122, and the mounting assembly 200 is rotationally connected to the first connecting segment 112.

[0063] More specifically, the locking member 130 can be a butterfly screw, and the clamping is achieved by the butterfly screw, which can realize quick disassembly and quick assembly of the connecting assembly 100 and the mounting base, and the clamping manner can be suitable for mounting bases of different diameters, which is beneficial to improve the adaptability of the rubberizing mechanism.
