[0058] The scheme of the present application will be described below in conjunction with the drawings and through specific embodiments.

[0059] As shown in FIGS. 1-4, the present embodiment provides a rubberizing device, which comprises a rack 1, a rubberizing disc 2 and a bearing disc 3. The rubberizing disc 2 is rotationally arranged on the rack 1, and the outer circumferential surface of the rubberizing disc 2 is provided with a rubber strip. The bearing disc 3 is rotationally arranged on the rack 1, and the rotation axis of the rubberizing disc 2 coincides with the rotation axis of the bearing disc 3. The bearing disc 3 is circumferentially provided with a plurality of bearing assemblies 31, the bearing assemblies 31 are configured to bear a cup 100, the cup 100 is provided with a cylindrical battery 101 inside, and the plurality of bearing assemblies 31 are arranged in a spaced manner with the rubberizing disc 2.

[0060] The cylindrical batteries 101 carried by the plurality of bearing assemblies 31 are distributed on the outer periphery of the adhesive disc 2. In order to enable the adhesive tape of the adhesive disc 2 to be attached to the outer periphery of the cylindrical batteries 101, the adhesive taping device further comprises a driving mechanism 4. The driving mechanism 4 comprises a plurality of first driving assemblies 41 which are arranged on the bearing disc 3 and correspond to the plurality of bearing assemblies 31. When the first driving assembly 41 rotates to the adhesive taping area, the first driving assembly 41 can drive the bearing assembly 31 to move along the radial direction of the bearing disc 3 so that the cylindrical battery 101 abuts against the adhesive tape.

[0061] The first driving assembly 41 and the corresponding bearing assembly 31 move synchronously, and the adhesive taping area is a fixed area of the rack 1. That is, in the circular track of the bearing disc 3, the range corresponding to the partial arc of the bearing assembly 31 is the adhesive taping area. When the bearing assembly 31 rotates to the adhesive taping area, the first driving assembly 41 drives the bearing assembly 31 to move along the radial direction of the bearing disc 3 so that the cylindrical battery 101 abuts against the adhesive tape. Therefore, in order to enable the adhesive tape to be attached to the outer periphery of the cylindrical battery 101, the rotational angular velocity of the bearing disc 3 is different from the rotational angular velocity of the adhesive disc 2.

[0062] Because the bearing disc 3 and the adhesive disc 2 have a rotational speed difference, the cylindrical battery 101 rolls relative to the outer periphery of the adhesive disc 2, so that the adhesive tape is pasted to the outer periphery of the cylindrical battery 101. The adhesive taping device can realize automatic and continuous adhesive taping operation on a plurality of cylindrical batteries 101, and has high adhesive taping quality and high efficiency, thereby reducing the cost.

[0063] The outer periphery of the adhesive disc 2 can be provided with a plurality of adhesive tapes at intervals. When the difference between the distance of the rotation of the outer periphery of the adhesive disc 2 and the distance of the rotation of the outer periphery of the bearing assembly 31 is greater than the length of the adhesive tape, the adhesive tape completely leaves the adhesive disc 2 and is attached to the side wall of the cylindrical battery 101. At this time, only the bearing assembly 31 needs to be reset, so that the cylindrical battery 101 is separated from the adhesive disc 2.

[0064] In the embodiment, because the size of the adhesive tape in the circumferential direction of the adhesive disc 2 is greater than the size of the two adjacent bearing assemblies 31 in the circumferential direction of the adhesive disc 2, or the number of the adhesive tapes on the outer periphery of the adhesive disc 2 is less than the number of the bearing assemblies 31 on the bearing disc 3, the rotational speed of the adhesive disc 2 is greater than the rotational speed of the bearing disc 3, so as to ensure the continuous adhesive taping operation.

[0065] As shown in FIG. 1, the adhesive taping device comprises a first power source 81 which is configured to drive the adhesive disc 2 and the bearing disc 3 to rotate. The transmission coefficient of the first power source 81 and the adhesive disc 2 and the transmission coefficient of the first power source 81 and the bearing disc 3 are different, so that the rotational angular velocity of the bearing disc 3 is different from the rotational angular velocity of the adhesive disc 2. One power source is used for driving, and the rotational speed difference is adjusted by a gear set, so that each structure can stably operate and perfectly cooperate, and the structural reliability is high.

[0066] The first driving assembly 41 can be electrically controlled to control the movement of the bearing assembly 31, for example, a linear driving structure such as a linear motor, a screw nut structure, or other structures capable of driving the bearing assembly 31 to move linearly.

[0067] As shown in FIGS. 5 and 6, the driving mechanism 4 further comprises a first driving disc 42 fixedly arranged on the rack 1, the first driving disc 42 comprising a first driving ring groove 421, the first driving ring groove 421 comprising a driving section 4211 and a release section 4212 connected in communication, and the radius of the driving section 4211 being smaller than the radius of the release section 4212. The first driving assembly 41 comprises a first sliding member 411 and a driving member 412, the first sliding member 411 comprising a first sliding part 413, the first sliding part 413 being slidingly arranged in the first driving ring groove 421, and the driving member 412 pressing the cylindrical battery 101 against the adhesive tape when the first sliding part 413 is located in the driving section 4211.

[0068] When the bearing disc 3 rotates, the first sliding part 413 of the first sliding member 411 moves in the driving ring groove 421, and when the first sliding part 413 slides from the release section 4212 to the driving section 4211, the radius of rotation of the first sliding part 413 decreases, which causes the first sliding member 411 to move along the radial direction of the bearing disc 3 to approach the adhesive applying disc 2. The driving member 412 is arranged on the first sliding member 411, so that the driving member 412 approaches the cylindrical battery 101 and presses the cylindrical battery 101 against the adhesive tape. When the first sliding part 413 slides from the driving section 4211 to the release section 4212, the first sliding member 411 moves along the radial direction of the bearing disc 3 to move away from the adhesive applying disc 2, so that the driving member 412 no longer presses the cylindrical battery 101, and the cylindrical battery 101 can be separated from the adhesive applying disc 2.

[0069] As shown in FIGS. 3 and 6, the first driving assembly 41 further comprises a driving plate 43 surrounding the first driving assembly 41, and the first driving assembly 41 further comprises a second sliding member 414 slidingly arranged on the first sliding member 411 along the vertical direction, the second sliding member 414 comprising a second sliding part 415, the second sliding member 414 being able to rise to make the driving member 412 higher than the cylindrical battery 101 when the second sliding part 415 slides on the driving plate 43, and the driving member 412 being arranged on the second sliding member 414.

[0070] Since the driving member 412 is pressed against the cylindrical battery 101 from the side of the cylindrical battery 101 away from the adhesive tray 2, in order to facilitate the loading and unloading of the cylindrical battery 101, the driving member 412 needs to be able to avoid the cylindrical battery 101. When the bearing assembly 31 moves out of the adhesive area, the second sliding part 415 of the second sliding member 414 in the corresponding first driving assembly 41 gradually slides onto the driving plate 43 and gradually rises under the driving of the top surface of the driving plate 43, thereby driving the driving member 412 to move upwards and reach a position higher than the cylindrical battery 101, so as to avoid the loading and unloading of the cylindrical battery 101.

[0071] Optionally, the driving plate 43 is arc-shaped, and the height of the top surface of the driving plate 43 gradually decreases from the middle to the two ends along the circumference of the bearing disc 3. When the bearing assembly 31 moves to one end of the driving plate 43, the second sliding part 415 of the second sliding member 414 in the corresponding first driving assembly 41 can move to the top surface of the driving plate 43 and rise and fall with the change of the height of the top surface.

[0072] The movement of the driving member 412 of the first driving assembly 41 is completely driven by the first driving disc 42 and the driving plate 43. Compared with electric control, the purely mechanical structure is more reliable and will not cause impact or interference due to errors. In the vertical direction, the projection of the driving plate 43 on the rack 1 is completely located outside the adhesive area. The first sliding part 413 and the second sliding part 415 are both pulleys to reduce friction and wear.

[0073] In the embodiment, the driving member 412 includes two driving rollers 4121 arranged at intervals, and the two driving rollers 4121 can simultaneously abut against the side wall of the cylindrical battery 101. The two driving rollers 4121 simultaneously abut against the side wall of the cylindrical battery 101, which can enable the cylindrical battery 101 to stably abut against the adhesive tray 2, and the driving rollers 4121 can rotate, thereby reducing the resistance when the cylindrical battery 101 is adhered with the adhesive strip and reducing wear.

[0074] In order to improve the degree of automation of the adhesive device, the adhesive device further includes a conveying line 5, a first end of the conveying line 5 is arranged at a loading position of the rack 1, and a second end of the conveying line 5 is arranged at an unloading position of the rack 1. The operator places the cup holder 100 containing the cylindrical battery 101 on the conveying line 5, and the cup holder 100 can be moved from the loading position of the rack 1 to the bearing assembly 31 rotating to the loading position, and rotates with the bearing assembly 31 to adhere the adhesive strip. When the bearing assembly 31 moves to the unloading position, the cup holder 100 is moved to the conveying line 5 again, and the operator can take out the cylindrical battery 101.

[0075] As shown in FIG. 1 and FIG. 2, the device further comprises a second power source 82, the transmission line 5 is driven to move by the second power source 82, and the operator can control the running speed of the transmission line 5 according to the position of the cylindrical battery 101 on the transmission line 5.

[0076] As shown in FIG. 3, FIG. 4 and FIG. 7, the bearing assembly 31 comprises a base 311 and a positioning piece 312, the base 311 is fixedly arranged on the bearing disc 3, and the positioning piece 312 is arranged on the base 311 and configured to abut against the cup 100 to position the cup 100. The positioning piece 312 can position the cup 100 when the cup 100 moves onto the base 311, thereby ensuring that the position of the cylindrical battery 101 does not deviate, so that the two drive rollers 4121 of the first drive assembly 41 can press the cylindrical battery 101 against the rubberizing disc 2.

[0077] The positioning piece 312 comprises two positioning forks 3121 arranged at intervals, and the two positioning forks 3121 are configured to abut against the sidewall of the cup 100 to position the cup 100. The two positioning forks 3121 can position the cup 100 from two points respectively, thereby improving the accuracy of positioning.

[0078] When the cylindrical battery 101 is pressed by the drive roller 4121, it will move in the radial direction of the bearing disc 3. In order to prevent the positioning piece 312 from blocking the cup 100, the bearing assembly 31 further comprises a connecting rod 313 and a sliding block 314, the positioning piece 312 is arranged on the base 311 to slide in the radial direction of the bearing disc 3, the first end 3131 of the connecting rod 313 is pivotally connected to the base 311, the second end 3132 of the connecting rod 313 is movably connected to the positioning piece 312, and the sliding block 314 is arranged on the base 311 to slide in the radial direction of the bearing disc 3, the sliding block 314 is configured to carry the cup 100, the sliding block 314 abuts against the connecting rod 313, and the abutting position is located between the first end 3131 and the second end 3132.

[0079] When the drive roller 4121 abuts against the cylindrical battery 101 and pushes the cylindrical battery 101 to move, the cup 100 will move together with the sliding block 314, at this time the sliding block 314 will push the connecting rod 313 to rotate around the rotation axis of the first end 3131, thereby driving the positioning piece 312 to move through the second end 3132. According to the geometric relationship, the distance moved by the sliding block 314 is less than the distance moved by the positioning piece 312, so at this time the positioning piece 312 is separated from the cylindrical battery 101 and does not block the cup 100 to prevent the cylindrical battery 101 from abutting against the rubberizing disc 2.

[0080] Optionally, the slider 314 is rotationally provided with a bearing table 3141 configured to bear the cup 100 and a synchronous wheel 3142 abutting against the sidewall of the cylindrical battery 101, the synchronous wheel 3142 being in transmission connection with the bearing table 3141 to enable synchronous rotation of the cup 100 and the cylindrical battery 101.

[0081] Since the cylindrical battery 101 rotates in the process of being pasted with the adhesive tape, the above structure enables synchronous rotation of the cup 100 and the cylindrical battery 101, avoids wear or increased resistance of rotation of the cylindrical battery 101 due to relative rotation between the cup 100 and the cylindrical battery 101, and enables the cylindrical battery 101 to freely rotate with the pasting disc 2, so as to facilitate pasting of the adhesive tape on the outer circumferential surface of the cylindrical battery 101.

[0082] Since the cylindrical battery 101 only needs to be covered with the end cover by the adhesive tape, the synchronous wheel 3142 can be arranged below the pasting disc 2. In the embodiment, the transmission between the bearing table 3141 and the synchronous wheel 3142 can be achieved by a gear set or a synchronous belt, as long as the transmission ratio is controlled to enable synchronous rotation of the cup 100 and the cylindrical battery 101.

[0083] As shown in FIG. 7, the bearing assembly 31 further includes a first elastic member 315 arranged between the base 311 and the positioning member 312, the first elastic member 315 being configured to reset the positioning member 312. When the bearing assembly 31 moves out of the pasting range, the first driving assembly 41 is disengaged from the cylindrical battery 101, at which time the positioning member 312 is reset under the drive of the first elastic member 315, and simultaneously drives the bearing table 3141 to be reset through the connecting rod 313, so as to facilitate the unloading operation of the cylindrical battery 101 pasted with the adhesive tape.

[0084] The number of adhesive tapes arranged on the outer circumferential surface of the pasting disc 2 is limited, as shown in FIGS. 1, 2 and 10. In order to enable the pasting device to continuously paste the cylindrical battery 101, the pasting device further includes a tape feeding mechanism 6, the tape feeding mechanism 6 including a tape feeding roll 61 and a pasting wheel 63, both of which are rotationally arranged on the rack 1, the pasting wheel 63 being in rolling abutment with the outer circumferential surface of the pasting disc 2, and the tape feeding roll 61 being wound with an adhesive tape 62, a free end of the adhesive tape 62 being located between the pasting wheel 63 and the pasting disc 2.

[0085] The pasting wheel 63 tightly pastes the free end of the adhesive tape 62 to the outer circumferential surface of the pasting disc 2, and when the pasting disc 2 rotates, the adhesive tape 62 is driven to pass through the gap between the pasting wheel 63 and the pasting disc 2, so that the adhesive tape 62 is fixed on the outer circumferential surface of the pasting disc 2, and the rotation of the tape feeding roll 61 continuously feeds the adhesive tape 62, so as to enable the pasting disc 2 to continuously provide the cylindrical battery 101 with the adhesive tape.

[0086] In the embodiment, the film 61 is also driven to rotate by the first power source 81 to avoid the film 62 being excessively stretched or broken, and ensure that the film 62 is kept at a proper tightness to be attached to the attaching disc 2.

[0087] The film 62 is in a long strip structure, and thus needs to be cut to form a film strip to be attached to the cylindrical battery 101. As shown in FIGS. 1, 2 and 8, the film-attaching device further comprises a film-cutting mechanism 7, which comprises a second driving assembly 71 and a cutter assembly 72. The cutter assembly 72 is swingably arranged on the frame 1, and the second driving assembly 71 is configured to drive the cutter assembly 72 to move close to the attaching disc 2 to cut the film 62.

[0088] The second driving assembly 71 needs to drive the cutter assembly 72 to move at equal intervals to ensure that the film 62 cut by the cutter assembly 72 forms film strips of equal length, thereby ensuring that the film strips attached to each cylindrical battery 101 have the same thickness.

[0089] As shown in FIG. 4, the outer periphery of the attaching disc 2 is provided with a plurality of suction holes 22, and the film 62 is suctioned and fixed to the outer periphery of the attaching disc 2 by the suction holes 22. Moreover, since the suction force of the suction holes 22 is smaller than the adhesive force between the film strip and the cylindrical battery 101, the film strip will be adhered and fixed to the cylindrical battery 101 when it contacts the outer surface of the cylindrical battery 101, thereby being separated from the outer periphery of the attaching disc 2, and completing the film-attaching operation on the cylindrical battery 101.

[0090] As shown in FIGS. 8 and 9, the second driving assembly 71 comprises a second driving disc 711, which comprises a driving surface 7111 provided with a driving protrusion 7113. The cutter assembly 72 comprises a support arm 721 swingably arranged on the frame 1, which is connected with a cutter 722 and a follower 726. When the second driving disc 711 rotates, the driving protrusion 7113 can drive the support arm 721 to swing to make the cutter 722 cut the film 62.

[0091] The driving surface 7111 of the second driving disc 711 is the outer periphery of the second driving disc 711. When the second driving disc 711 rotates, the follower 726 moves relative to the driving surface 7111. When the driving protrusion 7113 moves to the position of the follower 726, the follower 726 drives the support arm 721 to move, thereby driving the cutter 722 to move. At this time, the cutter 722 is close to the film 62 on the outer periphery of the attaching disc 2, and cuts the film 62 to form a film strip. When the driving protrusion 7113 is separated from the follower 726, the follower 726 returns to the original position, and the cutter 722 is separated from the film 62.

[0092] The follower 726 is a pulley to reduce friction and wear. In this embodiment, the second driving disc 711 is also driven to rotate by the first power source 81, and the rotation speed of the second driving disc 711 is adjusted by the gear set, so that each structure can operate stably and perfectly match, and the structural reliability is high.

[0093] As shown in FIGS. 8 and 9, the second driving disc 711 can also be provided with a second driving ring groove 7112, and the follower 726 is arranged in the second driving ring groove 7112. At this time, the inner side surface of the second driving ring groove 7112 is the driving surface 7111, and the driving protrusion 7113 is also arranged on the inner side surface of the second driving ring groove 7112.

[0094] When the cutter 722 approaches and abuts against the pasting disc 2, the adhesive tape 62 can not be cut off, which affects the pasting operation of the cylindrical battery 101. Therefore, the outer circumferential surface of the pasting disc 2 is provided with a plurality of cutting grooves 21 which are spaced apart in the circumferential direction, and the cutter 722 cuts off the adhesive tape 62 from the position of the cutting groove 21.

[0095] Since the cutter 722 can extend into the cutting groove 21, it can be ensured that the cutter 722 can cut off the adhesive tape 62, and at the same time, it can also avoid the cutter 722 from colliding with the pasting disc 2 to cause the blade to be blunt, thereby reducing the frequency of replacing the cutter 722 and improving the efficiency.

[0096] In this embodiment, the cutter assembly 72 further includes a pressing wheel 723, a support 725, and a second elastic member 724. The pressing wheel 723 is rotatably arranged on the support 725, the support 725 is slidably arranged on the support arm 721, and the second elastic member 724 is arranged between the support arm 721 and the support 725. When the cutter assembly 72 approaches the pasting disc 2, the pressing wheel 723 abuts against the pasting disc 2 to press the adhesive tape 62, and then the support 725 compresses the second elastic member 724 while the cutter 722 cuts off the adhesive tape 62. The second elastic member 724 can not only provide sufficient pressing force to the adhesive tape 62 by the pressing wheel 723, but also enable the pressing wheel 723 and the cutter 722 to move relatively, so that the cutter 722 can cut off the adhesive tape 62 when the pressing wheel 723 presses the adhesive tape 62.

[0097] The adhesive supplying of the adhesive supplying mechanism 6 and the cutting of the adhesive cutting mechanism 7 are both performed below the driving plate 43, so as to ensure that the driving member 412 does not block the outer circumferential surface of the pasting disc 2 and the adhesive tape 62, and avoid that the driving member 412 tears the adhesive tape 62 to cause the adhesive tape 62 to break.
