Unless otherwise specified, "plurality" means two or more.

[0066] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0067] The present application provides a rubber-coated roller 100, see Figure 1 , Figure 2 and Figure 3 The adhesive tape roller 100 includes a roller body 1 and a plurality of adsorbents 2, wherein the plurality of adsorbents 2 are arranged on the peripheral wall of the roller body 1 along the circumferential direction of the roller body 1, wherein the plurality of adsorbents 2 are configured to independently adsorb or release the adhesive tape J.

[0068] In this embodiment, when attaching the tape J to the material belt L, first, at least one tape J can be attached to each adsorbent 2, and the non-adhesive surface of the tape J faces the side close to the adsorbent 2, the adhesive surface faces the side away from the adsorbent 2, and the tape J is axially ( Figure 2Since the plurality of adsorbents 2 are arranged on the peripheral wall of the roller body 1 along the circumference of the roller body 1, and since the plurality of adsorbents 2 can adsorb the adhesive tape J independently, when at least one adhesive tape J is attached to each adsorbent 2, the adsorbent 2 can adsorb at least one adhesive tape J attached thereto to itself, so that the plurality of adhesive tapes J are arranged on the peripheral wall of the roller body 1 along a circle in the circumferential direction.

[0069] After the plurality of adhesive tapes J are arranged on the peripheral wall of the roller body 1 along the circumferential direction of the roller body 1, the peripheral wall of the roller body 1 can be pressed against the material belt L. Under the premise that the peripheral wall of the roller body 1 is pressed against the material belt L, when the roller body 1 rotates around its own axis and the material belt L moves along its own length direction ( Figure 3 When the roller body 1 moves in the Y-axis direction, the first adhesive tape among the multiple adhesive tapes J arranged on the peripheral wall of the roller body 1 will be able to be rolled and clamped between the material tape L and the adsorbent 2, so that the first adhesive tape can be attached to the material tape L through its own adhesive surface, wherein the first adhesive tape is any one of the multiple adhesive tapes J arranged on the peripheral wall of the roller body 1.

[0070] Since the plurality of adsorbents 2 can release the adhesive tape J independently, after the first adhesive tape is attached to the material tape L, the adsorbent 2 can release the first adhesive tape. After the adsorbent 2 releases the first adhesive tape, as the roller 1 rotates, the first adhesive tape will leave the adsorbent 2 and remain on the material tape L, thereby achieving the purpose of attaching the first adhesive tape to the material tape L. In the same way, see Figure 4 Other adhesive tapes among the plurality of adhesive tapes J arranged on the peripheral wall of the roller body 1 can also be attached to the material tape L in the same manner, thereby achieving the purpose of attaching the plurality of adhesive tapes J to the material tape L.

[0071] Among them, since the adsorbent 2 is arranged on the peripheral wall of the roller body 1 along the circumferential direction of the roller body 1, and the tape J is attached to the adsorbent 2, under the premise that the peripheral wall of the roller body 1 is pressed against the material belt L, when the roller body 1 rotates, the tape J can be rolled and clamped between the material belt L and the adsorbent 2, thereby achieving the purpose of attaching the tape J to the material belt L. When the tape J is attached to the material belt L by rolling and clamping, as the roller body 1 rotates, the sticky surface of the tape J gradually contacts the material belt L, rather than the entire sticky surface of the tape J contacting the material belt L at one time. Therefore, the gas between the tape J and the material belt L can be squeezed out from between the two during the rolling and clamping process, so that there will be no bubbles between the tape J and the material belt L, thereby achieving a better adhesive effect.

[0072] In addition, since multiple adsorption members 2 are arranged on the peripheral wall of the roller body 1 along the circumference of the roller body 1, when at least one adhesive tape J is attached to each adsorption member 2, multiple adhesive tapes J can be arranged on the peripheral wall of the roller body 1 along a circle in the circumferential direction. In this way, under the premise that the peripheral wall of the roller body 1 is pressed against the material belt L, the roller body 1 can rotate one circle to attach multiple adhesive tapes J to the material belt L at one time, so that the gluing efficiency of the glue-applying roller 100 is higher.

[0073] In addition, when a plurality of tapes J are attached to the adsorbent 2, the spacing between two adjacent tapes J attached to the adsorbent 2 along the circumferential direction of the roller body 1 can be adjusted, so as to change the spacing between two adjacent tapes J attached to the material strip L, so as to meet the requirements of the material strip L for different spacing between two adjacent tapes J attached to itself, and has wider adaptability.

[0074] It should be noted that the material strip L may be a pole piece or any other material strip that needs to be attached with the adhesive tape J, and this embodiment does not limit this.

[0075] There are many ways to implement the above-mentioned adsorption component 2. In one possible implementation, the above-mentioned adsorption component 2 can be an electrostatic sheet. When the adsorption component 2 is an electrostatic sheet, the purpose of making the adsorption component 2 adsorb or release the tape J can be achieved by making the electrostatic sheet powered or de-powered.

[0076] Of course, the above-mentioned adsorption member 2 can also be implemented in other possible ways. For example, in another possible implementation, see Figure 1 The adsorption member 2 includes: a plurality of adsorption holes 21, each of which is provided with a peripheral wall of the roller body 1, and the plurality of adsorption holes 21 form an adsorption hole group 20, the plurality of adsorption hole groups 20 are isolated from each other, and the plurality of adsorption holes 21 in each adsorption hole group 20 are connected to each other.

[0077] Since the multiple adsorption hole groups 20 are isolated from each other, the multiple adsorption holes 21 in each adsorption hole group 20 are connected to each other. Therefore, the multiple adsorption hole groups 20 can achieve the purpose of independently adsorbing or releasing the tape J.

[0078] When the adsorption member 2 includes a plurality of adsorption holes 21, the purpose of adsorbing or releasing the tape J can be achieved by providing negative pressure to the plurality of adsorption holes 21 or stopping providing negative pressure. This implementation method is technically mature and low-cost, and can ensure the reliability of the operation of the adsorption member 2 to a certain extent and reduce the cost of the adsorption member 2.

[0079] Of course, the adsorption component 2 can also be implemented by other possible structures, as long as it can achieve the purpose of adsorbing or releasing the tape J. This embodiment does not limit the implementation method of the adsorption component 2.

[0080] When the adsorption member 2 includes a plurality of adsorption holes 21, in some embodiments, see Figure 1 and Figure 5 The roller body 1 is enclosed to form a plurality of mutually isolated cavities 11, and the plurality of cavities 11 correspond one-to-one to the plurality of adsorption hole groups 20. Each cavity 11 is connected to each adsorption hole 21 in the corresponding adsorption hole group 20, and an exhaust hole 12 connected to the corresponding cavity 11 is provided on the roller body 1 corresponding to each cavity 11.

[0081] Since each cavity 11 is connected to each adsorption hole 21 in the corresponding adsorption hole group 20, an air extraction hole 12 connected to the corresponding cavity 11 is provided on the roller body 1 corresponding to each cavity 11. Therefore, when the air in the cavity 11 is sucked through the air extraction hole 12 to make the cavity 11 into a negative pressure state, the multiple adsorption holes 21 connected to the cavity 11 can all be changed into a negative pressure state. It can be seen that by making each cavity 11 connected to each adsorption hole 21 in the corresponding adsorption hole group 20, it is only necessary to provide negative pressure to the cavity 11 through the air extraction hole 12, so that the multiple adsorption holes 21 connected to the cavity 11 can all be changed into a negative pressure state. Compared with the method of providing a separate air pipe for each adsorption hole 21 to provide a separate negative pressure for each adsorption hole 21 to make the multiple adsorption holes 21 into a negative pressure state, such a setting can simplify the structure of the rubber-coated roller 100 and reduce the cost of the rubber-coated roller 100.

[0082] Among them, see Figure 5 and Figure 6 The number of the above-mentioned cavities 11 can be two ( Figure 5 The number of the hollow cavities 11 is two), or three, four or eight ( Figure 6 The number of hollow cavities 11 is eight), etc. It is only necessary to make the number of cavities 11 the same as the number of adsorption hole groups 20, and make the cavities 11 correspond to the adsorption hole groups 20 one by one. The present embodiment does not limit the number of cavities 11.

[0083] In order to make the negative pressure at each position in the cavity 11 relatively balanced, in some embodiments, see Figure 5 , a plurality of air extraction holes 12 are provided corresponding to each cavity 11. In this way, air can be extracted at multiple positions of the cavity 11 through the air extraction holes 12, so that the negative pressure at each position in the cavity 11 can be relatively balanced.

[0084] Specifically, see Figure 5 The number of the exhaust holes 12 corresponding to each cavity 11 may be two, or may be three or four, etc. This embodiment does not limit this.

[0085] In order to avoid mutual interference between the adhesive tapes J attached to two adjacent adsorbents 2 after the adhesive tapes J are attached to the multiple adsorbents 2, in some embodiments, Figure 1 , two adsorbents 2 adjacent to each other along the circumference of the roller body 1 are spaced apart from each other. By spaced apart from each other between two adsorbents 2 adjacent to each other along the circumference of the roller body 1, on the one hand, interference between two adjacent adsorbents 2 can be avoided, on the other hand, two adjacent adsorbents 2 can be made relatively independent to avoid mutual influence, and on the other hand, after the adhesive tapes J are attached to the multiple adsorbents 2, interference between the adhesive tapes J attached to two adjacent adsorbents 2 can be avoided.

[0086] The present application also provides a glue sticking device 200, see Figure 7 , Figure 8 and Fig. 9 The glue application device 200 includes: a glue application roller assembly 3, a glue preparation assembly 4 and a pressing assembly 5, wherein the glue application roller assembly 3 includes a glue application roller driving member 31 and a glue application roller 100, the glue application roller driving member 31 is used to drive the roller body 1 to rotate around its own axis, the glue preparation assembly 4 is used to attach at least one adhesive tape J to each adsorption member 2, and each adhesive tape J extends along the axial direction of the glue application roller 100, and the pressing assembly 5 includes a pressing driving assembly 51 and a pressing member 52, the pressing driving assembly 51 is connected to the pressing member 52, and a material passing gap 6 is provided between the pressing member 52 and the adsorption member 2, and the material passing gap 6 is used for the feeding tape L to pass through, and the pressing driving assembly 51 is used to drive the pressing member 52 to move in a direction close to or away from the roller body 1, so that the pressing member 52 presses against or separates from the adsorption member 2.

[0087] Among them, the structure of the rubber coating roller 100 can be the same as the structure of the rubber coating roller 100 described in any of the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the rubber coating roller 100 in the above embodiments, which will not be repeated in this embodiment.

[0088] In this embodiment, when the adhesive tape J is attached to the material belt L, first, at least one adhesive tape J can be attached to each adsorbent 2 through the adhesive preparation component 4, and the non-adhesive surface of the adhesive tape J faces the side close to the adsorbent 2, the adhesive surface faces the side away from the adsorbent 2, and the adhesive tape J is axially ( Figure 8 X-axis direction).

[0089] Next, under the premise that the material strip L is arranged in the material passing gap 6, the pressing driving assembly 51 can drive the pressing member 52 to move in the direction close to the roller body 1, so that the pressing member 52 presses against the adsorption member 2. When the pressing member 52 presses against the adsorption member 2, the rubber roller driving member 31 can drive the roller body 1 to rotate around its own axis, and at the same time, the material strip L moves along its own length direction ( Fig. 9 In the process that the roller body 1 rotates around its own axis and the material strip L moves along its own length direction, the purpose of attaching multiple tapes J to the material strip L can be achieved.

[0090] Since the adsorbent 2 is arranged on the peripheral wall of the roller body 1 along the circumferential direction of the roller body 1, and the adhesive tape J is attached to the adsorbent 2, under the premise that the pressing member 52 presses against the adsorbent 2, when the adhesive roller driving member 31 drives the roller body 1 to rotate, the adhesive tape J can be rolled and clamped between the material strip L and the adsorbent 2, thereby achieving the purpose of attaching the adhesive tape J to the material strip L. When the adhesive tape J is attached to the material strip L by rolling and clamping, as the roller body 1 rotates, the adhesive surface of the adhesive tape J gradually contacts the material strip L, rather than the entire adhesive surface of the adhesive tape J contacting the material strip L at once, so that the gas between the adhesive tape J and the material strip L can be squeezed out from between the two, so that there will be no bubbles between the adhesive tape J and the material strip L, so that the adhesive effect is better.

[0091] In addition, since multiple adsorption members 2 are arranged on the peripheral wall of the roller body 1 along the circumference of the roller body 1, when at least one adhesive tape J is attached to each adsorption member 2, multiple adhesive tapes J can be arranged on the peripheral wall of the roller body 1 along the circumference. In this way, under the premise that the peripheral wall of the roller body 1 is pressed against the material belt L, the roller body 1 can rotate one circle to attach multiple adhesive tapes J to the material belt L at one time, so that the gluing efficiency of the glue-applying roller 100 is higher.

[0092] In addition, when a plurality of tapes J are attached to the adsorbent 2, the spacing between two adjacent tapes J attached to the adsorbent 2 along the circumferential direction of the roller body 1 can be adjusted, so as to change the spacing between two adjacent tapes J attached to the material strip L, so as to meet the requirements of the material strip L for different spacing between two adjacent tapes J attached to itself, and has wider adaptability.

[0093] It should be noted that the above-mentioned rubber-applying roller driving component 31 can be a motor or any other possible component, as long as it can drive the roller body 1 to rotate around its own axis. This embodiment does not limit the rubber-applying roller driving component 31.

[0094] In some embodiments, see Figure 7 and Fig. 9 The pressing member 52 is a pressure roller, which is rotatably arranged on the pressing driving assembly 51 around its own axis, and the axial direction of the pressure roller is parallel to the axial direction of the roller body 1.

[0095] Since the pressure roller is rotatably arranged on the pressing drive assembly 51 around its own axis, the axial direction of the pressure roller is parallel to the axial direction of the roller body 1. Therefore, when the pressing member 52 presses against the adsorption member 2 and the roller body 1 rotates around its own axis and the material strip L moves along its own length direction, the pressure roller can adapt to the rotation of the roller body 1 and rotate together, thereby reducing the friction between the material strip L and the pressure roller, making the material strip L move more smoothly along its own length direction.

[0096] The pressing member 52 being a pressing roller is only one possible implementation method given in this embodiment. Of course, the pressing member 52 may also be a pressing block, etc. This embodiment does not limit the pressing member 52.

[0097] In some embodiments, see Figure 7 The pressing driving assembly 51 includes: a pressing mounting seat 511, a pressing movable member 512 and a pressing driving member 513, wherein the pressing movable member 512 is movably arranged on the pressing mounting seat 511 along a direction approaching or moving away from the roller body 1, the pressing member 52 is arranged on the pressing movable member 512, the pressing driving member 513 is arranged on the pressing mounting seat 511 and connected to the pressing movable member 512, and the pressing driving member 513 is used to drive the pressing movable member 512 to move along a direction approaching or moving away from the roller body 1.

[0098] Since the pressing movable member 512 is movably arranged on the pressing mounting seat 511 in a direction approaching or moving away from the roller body 1, and the pressing member 52 is arranged on the pressing movable member 512, when the pressing driving member 513 drives the pressing movable member 512 to move in a direction approaching or moving away from the roller body 1, the pressing member 52 can be synchronously driven to move in a direction approaching or moving away from the roller body 1, thereby achieving the purpose of making the pressing member 52 press against or separate from the adsorption member 2.

[0099] Among them, since the pressing movable member 512 is movably arranged on the pressing mounting seat 511 in a direction close to or away from the roller body 1, when the pressing driving member 513 drives the pressing movable member 512 to move in a direction close to or away from the roller body 1, the pressing movable member 512 can move more smoothly and stably.

[0100] Specifically, there are many ways to movably set the pressing movable member 512 on the pressing mounting seat 511 along the direction approaching or away from the roller body 1. In one possible implementation, the pressing movable member 512 can be movably set on the pressing mounting seat 511 along the direction approaching or away from the roller body 1 through a slide rail assembly. Of course, the pressing movable member 512 can also be movably set on the pressing mounting seat 511 along the direction approaching or away from the roller body 1 in other ways, and this embodiment is not limited to this.

[0101] It should be noted that the above-mentioned pressure driving member 513 may include but is not limited to a pneumatic cylinder and an electric cylinder, and the above-mentioned pressure moving member 512 and the pressure mounting seat 511 may both be plate-like structures or other possible structures. This embodiment does not limit the pressure driving member 513, the pressure moving member 512 and the pressure mounting seat 511.

[0102] In order to speed up the efficiency of the adhesive preparation component 4 in attaching the adhesive tape J to each adsorbent 2, that is, in order to speed up the adhesive preparation efficiency of the adhesive preparation component 4, in some embodiments, see Fig. 9 The number of the rubber preparation components 4 is multiple, and the multiple rubber preparation components 4 are arranged at intervals along the circumference of the roller body 1. When the number of the rubber preparation components 4 is multiple, the multiple rubber preparation components 4 can attach adhesive tapes J to multiple adsorbents 2 at the same time, so the rubber preparation efficiency of the rubber preparation components 4 can be improved.

[0103] Specifically, the number of the above-mentioned glue preparation components 4 can be two, three or four, etc., and this embodiment does not limit the number of the glue preparation components 4.

[0104] In some embodiments, see Fig. 9 , Fig.10 and Fig.11 The adhesive preparation component 4 includes: a tape attaching component 41, a tape unwinding component 42 and a cutting component 43, wherein the tape unwinding component 42 is used to unwind the tape J to the tape attaching component 41, the tape attaching component 41 is used to attach the tape J to the adsorption component 2, and the cutting component 43 is used to cut the tape J.

[0105] In this embodiment, when the tape J needs to be attached to the adsorbent 2, first, the tape J can be unwound to the tape attaching component 41 through the tape unwinding component 42, and then, the tape J can be attached to the adsorbent 2 through the tape attaching component 41. Finally, the tape J can be cut off through the cutting component 43. At this point, the purpose of attaching the tape J in the unwinding component 42 to the adsorbent 2 can be achieved, that is, the purpose of preparing glue is achieved.

[0106] Among them, due to the cooperation between the tape unwinding component 42 and the cutting component 43, the tape J in the unwinding component 42 can be cut from the unwinding component 42, and the cut tape J can be attached to the adsorption component 2, that is, the glue preparation component 4 can automatically cut the tape J and automatically attach the cut tape J to the adsorption component 2 without the participation of personnel. Therefore, the degree of automation is relatively high, which can achieve the purpose of saving manpower and reducing labor costs.

[0107] Among them, the above-mentioned tape unwinding component 42 may include a material tray, which is rotatably arranged around its own axis, and a tape roll may be sleeved on the material tray. In this way, when the material tray rotates around its own axis, the purpose of unwinding the tape J in the tape roll to the tape attaching component 41 can be achieved.

[0108] There are many ways to implement the tape attaching assembly 41. In one possible implementation, see Fig.11 The adhesive tape attaching component 41 includes: an adhesive suction component 411, an adhesive pulling moving component 412 and an adhesive rolling component 413, wherein the adhesive suction component 411 is fixedly arranged, and the adhesive suction component 411 has an adsorption surface 4111 for adsorbing the adhesive tape J, the adhesive tape unwinding component 42 is used to unwind the adhesive tape J to the adsorption surface 4111, and the adsorption surface 4111 can adsorb or release the adhesive tape J, and the adhesive pulling moving component 412 includes an adhesive pulling driving component 4121 and an adhesive pulling moving component 4122, and the adhesive pulling driving component 4121 is used to drive the adhesive pulling moving component 4122 to move along the axial direction of the roller body 1 ( Fig.11 The rubber rolling component 413 is arranged on the rubber pulling movable part 4122, and the rubber rolling component 413 includes a rubber rolling driving part 4131 and a rubber rolling roller 4132. The rubber rolling roller 4132 is rotatably arranged on the rubber rolling driving part 4131. The rubber rolling driving part 4131 is used to drive the rubber rolling roller 4132 to move so that the rubber rolling roller 4132 can abut against the adsorption surface 4111 or the adsorption part 2. When the rubber pulling movable part 4122 reciprocates along the axial direction of the roller body 1, it can drive the rubber rolling roller 4132 to roll relative to the adsorption surface 4111 and the adsorption part 2 respectively.

[0109] In this embodiment, when the tape J is attached to the adsorption member 2 by the tape attaching assembly 41, the tape unwinding assembly 42 unwinds the tape J to the adsorption surface 4111 and the adhesive surface of the tape J faces away from the adsorption surface 4111 ( Fig.11 Under the premise that the sticky side of the tape J is facing upwards, firstly, the tape J can be fixed by adsorption through the adsorption surface 4111, and then the rubber roller driving member 4131 can drive the rubber roller 4132 to move in the direction close to the adsorption surface 4111, so that the rubber roller 4132 abuts against the tape J located on the adsorption surface 4111. When the rubber roller 4132 abuts against the tape J, since the sticky side of the tape J faces away from the adsorption surface 4111, the tape J will adhere to the rubber roller 4132.

[0110] After the adhesive tape J is bonded to the rubber roller 4132, the adhesive pulling driving member 4121 can drive the adhesive pulling moving member 4122 along the axial direction of the roller body 1 in a direction opposite to the direction in which the adhesive tape unwinding assembly 42 unwinds the adhesive tape J ( Fig.11 The rubber roller 4132 moves in the positive direction of the center X-axis, so that the rubber roller 4132 rolls relative to the adsorption surface 4111, and the adsorption surface 4111 releases the tape J. During the rolling of the rubber roller 4132, the tape J will be wound around the peripheral wall of the rubber roller 4132.

[0111] After the adhesive tape J is wound around the peripheral wall of the rubber roller 4132, the rubber roller driving member 4131 can drive the rubber roller 4132 to move in a direction away from the adsorption surface 4111, so that the rubber roller 4132 leaves the adsorption surface 4111, and then the rubber pulling driving member 4121 can drive the rubber pulling moving member 4122 to move along the axial direction of the roller body 1 in the same direction as the direction in which the tape unwinding assembly 42 unwinds the adhesive tape J ( Fig.11 The rubber roller 4132 can be driven by the rubber driving component 4131 to move in the negative direction of the center X-axis, and at the same time, the rubber roller 4132 can be driven by the rubber driving component 4131 to move in the direction close to the adsorption component 2, so that the rubber roller 4132 wound with the adhesive tape J abuts against the adsorption component 2 located on the peripheral wall of the roller body 1. At this time, when the rubber pulling driving component 4121 drives the rubber pulling movable component 4122 to move along the axial direction of the roller body 1, the rubber roller 4132 can be rolled relative to the adsorption component 2, thereby achieving the purpose of attaching the adhesive tape J wound on the peripheral wall of the rubber roller 4132 to the adsorption component 2.

[0112] Among them, since the length of the adhesive tape J attached to the adsorption member 2 is determined by the amount of the adhesive tape J wound on the peripheral wall of the rubber roller 4132, and according to the above description, the amount of the adhesive tape J wound on the peripheral wall of the rubber roller 4132 can be determined by the rolling distance of the rubber roller 4132 on the adsorption surface 4111, and the rolling distance of the rubber roller 4132 on the adsorption surface 4111 can be determined by controlling the driving stroke of the rubber pulling driving member 4121 and the rubber rolling driving member 4131, the rubber pulling driving member 4132 can be determined by the driving stroke of the rubber pulling driving member 4121 and the rubber rolling driving member 4131. 121 and the driving stroke of the rubber rolling driver 4131 can be flexibly controlled as needed. Therefore, by controlling the driving stroke of the rubber pulling driver 4121 and the rubber rolling driver 4131, the amount of the tape J wound on the peripheral wall of the rubber rolling roller 4132 can be flexibly controlled, thereby achieving the purpose of freely controlling the length of the tape J attached to the adsorbent 2, so that the tape attaching component 41 can more freely adjust the length of the tape J attached to the adsorbent 2 according to actual needs, which is very convenient and flexible.

[0113] The adhesive suction member 411 may be an adsorption block, and adsorption holes may be provided on the adsorption block. The side of the adsorption block where the adsorption holes are located is the adsorption surface 4111, and the purpose of adsorbing or releasing the adhesive tape J can be achieved through the adsorption holes.

[0114] The above-mentioned glue pulling driving component 4121 can be a linear motor, and the above-mentioned glue rolling driving component 4131 can be a cylinder or an electric cylinder, etc., which is not limited in this embodiment.

[0115] According to the above description, the rubber roller 4132 needs to be rotatable relative to the rubber roller driving member 4131 only when the rubber roller 4132 rolls relative to the adsorption surface 4111 and the adsorption member 2, and the rubber roller 4132 does not need to rotate at other times. In order to avoid the situation where the rubber roller 4132 rotates unnecessarily at other times, in some embodiments, see Fig.11 The rubber rolling assembly 413 further includes a locking member 4133 , which can lock or unlock the rotation of the rubber rolling roller 4132 relative to the rubber rolling driving member 4131 .

[0116] By setting the locking member 4133, the rotation of the rubber roller 4132 relative to the rubber roller driving member 4131 can be locked or unlocked according to the situation, so that the rotation timing of the rubber roller 4132 becomes controllable, thereby avoiding the unnecessary rotation of the rubber roller 4132.

[0117] The locking member 4133 may be a cylinder. When the locking member 4133 is a cylinder, when it is necessary to lock the rotation of the rubber roller 4132 relative to the rubber roller driving member 4131, the telescopic shaft of the cylinder may be pressed against the rubber roller 4132, so that the rotation of the rubber roller 4132 relative to the rubber roller driving member 4131 may be locked. When it is necessary to unlock the rotation of the rubber roller 4132 relative to the rubber roller driving member 4131, the telescopic shaft of the cylinder may be moved away from the rubber roller 4132, so that the rubber roller 4132 may rotate freely, thereby achieving the purpose of unlocking the rotation of the rubber roller 4132 relative to the rubber roller driving member 4131.

[0118] Of course, the locking member 4133 may also be other possible components, as long as it can achieve the purpose of locking or unlocking the rotation of the rubber roller 4132 relative to the rubber roller driving member 4131, and this embodiment is not limited to this.

[0119] In some embodiments, the cutting assembly 43 may include a cutting drive and a cutter. When the cutting drive drives the cutter to move toward the direction close to the material strip L, the purpose of cutting the material strip L can be achieved.

[0120] The present application also provides a winding device 300, see Fig.12 The winding device 300 includes a glue applying device 200 .

[0121] Among them, the structure of the gluing device 200 can be the same as the structure of the gluing device 200 described in any of the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the gluing device 200 in the above embodiments, which will not be repeated in this embodiment.

[0122] In this embodiment, since the gluing device 200 can ensure that there are no bubbles between the adhesive tape J and the material tape L, the gluing effect is better, the gluing efficiency is higher, and it can meet the material tape L's requirements for different distances between two adjacent adhesive tapes J attached to itself, and has wider adaptability. Based on this, when the winding equipment 300 includes the gluing device 200, the product quality manufactured by the winding equipment 300 can be better.
