The preferred embodiments of the present invention will now be described with reference to the accompanying drawings, which are given by way of illustration.

Referring to fig. 1, a lithium battery pelleter 100 of the present invention includes a frame 10, and a tape wheel 20, a tape opening mechanism 30, a tape pressing mechanism 40, a cutting mechanism 50, a tape pulling mechanism 60, and a roll-on-tape mechanism 70, which are mounted on the frame 10. The gummed paper rolling mechanism 70 is arranged side by side with the gummed paper pulling mechanism 60 in the vertical direction (i.e. indicated by the double arrow B) of the frame 10, so that the actions between the gummed paper rolling mechanism 70 and the gummed paper pulling mechanism 60 are more coordinated, and the gummed paper 200 pulled out by the gummed paper pulling mechanism 60 is more reliably adsorbed by the gummed paper rolling mechanism 70. The glue pulling mechanism 60, the cutting mechanism 50, the glue pressing mechanism 40, the glue opening mechanism 30 and the tape wheel 20 are sequentially arranged along the left-right direction (i.e. indicated by the double arrow a) of the rack 10, and a first roll-on surface 71a or a second roll-on surface 71b described below is located at a glue preparation station when rotating to be aligned with the glue pulling mechanism 60, as shown in fig. 1, so as to ensure that the glue paper 200 pulled by the glue pulling mechanism 60 is reliably transferred to the first roll-on surface 71a or the second roll-on surface 71b located at the glue preparation station. Specifically, to further improve the efficiency, the adhesive tape wheel 20, the adhesive tape opening mechanism 30, the adhesive tape pressing mechanism 40, the cutting mechanism 50, the adhesive tape pulling mechanism 60 and the adhesive tape rolling mechanism 70 together form a sheet making unit 100a, and the sheet making unit 100a is symmetrically arranged on the frame 10, but not limited thereto. More specifically, the following:

as shown in fig. 1 to 4, the roll gummed paper mechanism 70 includes a roll gumming shaft 71 and a rotary driver 72 for driving the roll gumming shaft 71 to rotate. The side surface of the rolling shaft 71 is provided with a first rolling surface 71a and a second rolling surface 71b which are separated from each other along the circumferential direction of the rolling shaft 71, the interior of the rolling shaft 71 is provided with a first vacuum channel 71c and a second vacuum channel 71d which are not communicated with each other, the inlets of the first vacuum channel 71c and the second vacuum channel 71d are respectively used for being communicated with an external vacuum generating device, and the first vacuum channel 71c and the second vacuum channel 71d are respectively controlled by the external vacuum generating device, so that the first vacuum channel 71c and the second vacuum channel 71d are independent from each other and do not interfere with each other; the outlet 712 of the first vacuum channel 71c is located on the first roll surface 71a, so as to facilitate the adhesive tape 200 pulled by the adhesive pulling mechanism 60 to be adsorbed on the first roll surface 71a, or facilitate the adhesive tape 200 adsorbed on the first roll surface 71a to be transferred to the pole piece when the vacuum of the first vacuum channel 71c is lost; the outlet 714 of the second vacuum channel 71d is located on the second rolling surface 71b, so as to facilitate the adhesive tape 200 pulled by the adhesive pulling mechanism 60 to be adsorbed on the second rolling surface 71b, or facilitate the adhesive tape 200 adsorbed on the second rolling surface 71b to be attached to the pole piece when the vacuum of the second vacuum channel 71d is lost; the first rolling surface 71a and the second rolling surface 71b are alternately switched at the glue preparation station in the process that the rotary driver 72 drives the rolling shaft 71 to rotate, that is, when the first rolling surface 71a rotates to the glue preparation station, correspondingly, the second rolling surface 71b rotates away from the glue preparation station to meet the glue application requirement; when the second roll-on surface 71b rotates to the glue preparation station, correspondingly, the first roll-on surface 71a rotates away from the glue preparation station, so that the purpose that the first roll-on surface 71a and the second roll-on surface 71b are alternately switched at the glue preparation station is realized. Specifically, the outlets 712 of the first vacuum channels 71c are arranged in a matrix on the first roll surface 71a to improve the uniformity of the adsorption of the gummed paper 200 all over the first roll surface 71 a; the outlets 714 of the second vacuum channels 71d are arranged in a matrix on the second roll surface 71b to improve the uniformity of the suction of the gummed paper 200 throughout the second roll surface 71 b. More specifically, the rolling shaft 71 has a first radial boss 71e and a second radial boss 71f spaced apart in the circumferential direction of the rolling shaft 71, the first rolling surface 71a is located on the first radial boss 71e, and the second rolling surface 71b is located on the second radial boss 71f, so that the interference of the other side surfaces 711 of the rolling shaft 71 on the adsorption or transfer work of the first rolling surface 71a and the second rolling surface 71b can be avoided, and the adsorption reliability of the first rolling surface 71a and the second rolling surface 71b on the adhesive paper 200 or the reliability of the transfer of the adhesive paper 200 to the pole piece can be further ensured. For example, the first rolling surface 71a and the second rolling surface 71b are located on the same cylindrical side surface P centered on the axis of the rolling shaft 71; the first rolling surface 71a and the second rolling surface 71b are arranged symmetrically about the axial center of the rolling shaft 71, but not limited thereto.

As shown in fig. 1 and 2, the rotary driver 72 drives the rolling contact shaft 71 to rotate through belt transmission, but the rolling contact shaft 71 can also be driven to rotate through chain transmission or gear transmission according to actual needs.

For precise position control, the roll sticker mechanism 70 further includes a roll sticker sensor 76, a first trigger piece 77 for aligning with the first roll sticker 71a, and a second trigger piece 78 for aligning with the second roll sticker 71b, the roll sticker sensor 76 is mounted on the frame 10, the first trigger piece 77 and the second trigger piece 78 are mounted at the end of the driven pulley 74, and the first trigger piece 77 and the second trigger piece 78 are further symmetrically arranged with respect to the center of the driven pulley 74; therefore, when the first trigger piece 77 rotates to a position aligned with the roll-on sensor 76, the operation of the rotary actuator 72 is temporarily stopped, so that the first roll-on surface 71a is located at the glue preparing station, and when the second trigger piece 78 rotates to a position aligned with the roll-on sensor 76, the operation of the rotary actuator 72 is temporarily stopped, so that the second roll-on surface 71b is located at the glue preparing station. In order to make the arrangement of the rubberized paper rolling mechanism 70 on the frame 10 more reasonable, the rotary driver 71 is located on the back side of the frame 10 (i.e. the side facing away from the reader in fig. 1), and the rolling shaft 71, the driven pulley 74, the first trigger piece 77 and the second trigger piece 78 are located on the front side of the frame 10 (i.e. the side facing the reader in fig. 1), and the transmission belt 75 is inserted into the frame 10, but not limited thereto.

Therefore, when pulling the glue, firstly, the glue pulling motor 61 drives the glue pulling slide carriage 62 to slide to the glue pressing mechanism 40, and then the second air cylinder 64 drives the pressure matching block 66 to slide to a position aligned with the pressure matching shaft 67; at this time, the first cylinder 63 drives the pivot support 65 to drive the pressure distribution shaft 67 to abut against the pressure distribution block 66, so that the adhesive paper 200 at the pressure-sensitive adhesive mechanism 40 is clamped by the pressure distribution shaft 67 and the pressure distribution block 66; then, the glue pressing mechanism 40 releases the glue pressing effect on the gummed paper 200, the gummed slide carriage 62 is driven by the gummed motor 61 to slide to a position far away from the gummed mechanism 40, the gummed paper 200 is pressed by the gummed mechanism 40, and simultaneously, the cutting mechanism 50 cuts off the gummed paper 200, so that the gummed paper 200 with a length matched with the first roll-on surface 71a or the second roll-on surface 71b is pulled out by the gummed mechanism 60; finally, the second cylinder 64 drives the pressure distribution block 66 to be staggered from the pressure distribution shaft 67 to provide an avoidance position; meanwhile, the first air cylinder 63 drives the pressure distribution shaft 67 to pivot and swing against the first rolling surface 71a or the second rolling surface 71b, so that the pulled adhesive tape 200 is pressed on the first rolling surface 71a or the second rolling surface 71b, and the adhesive distribution shaft 67 uniformly presses the adhesive tape 200 on the first rolling surface 71a or the second rolling surface 71b under the action of the adhesive tape pulling motor 61 driving the adhesive tape pulling slide carriage 62 to slide towards the adhesive tape pressing mechanism 50; and in the process that the pressure-distribution shaft 67 presses the gummed paper 200 on the first roll surface 71a or the second roll surface 71b, the gummed paper 200 is vacuum-absorbed on the first roll surface 71a or the second roll surface 71b under the action of the first vacuum channel 71c or the second vacuum channel 71 d.

As shown in fig. 1 and 8, the cutting mechanism 50 includes a cutting cylinder 51 and a cutter 52, and the cutting cylinder 51 is mounted on the frame 10 and drives the cutter 52 to move up and down, so as to simplify the structure of the cutting mechanism 50. Preferably, the cutting mechanism 50 is located on the front surface of the frame 10, but not limited thereto. In order to make the structure of the lithium battery flaker 100 of the present invention more reasonable and compact, the cutting mechanism 50 is located on the front side of the frame 10, but not limited thereto.

The working principle of the lithium battery pelleter is explained with the accompanying drawings: the first roll-on surface 71a glue preparation process: the rotary driver 72 drives the rolling shaft 71 to rotate, so that the first rolling surface 71a of the rolling shaft 71 is positioned at the glue preparation station and the second rolling surface 71b is far away from the glue preparation station; then, the glue pulling mechanism 60 pulls glue in a direction away from the glue pressing mechanism 40, and the glue pressing mechanism 40 is released; when the glue pulling mechanism 60 reaches a preset position, the glue pressing mechanism 40 presses tightly; the cutting mechanism 50 acts to cut off the adhesive tape 200 between the adhesive tape pulling mechanism 60 and the adhesive tape pressing mechanism 40; next, the adhesive opening mechanism 30 is actuated to drive the adhesive tape wheel 20 to release adhesive; meanwhile, the second air cylinder 64 in the glue pulling mechanism 60 drives the pressure distribution block 66 to slide to an avoidance position staggered with the pressure distribution shaft 67, the first air cylinder 63 drives the pivot swing bracket 65 and the pressure distribution shaft 67 to move towards the position close to the first rolling surface 71a together, and the gummed paper 200 pulled out by the glue pulling mechanism 60 is adsorbed to the first rolling surface 71a under the vacuum adsorption of the first rolling surface 71 a; at this time, under the action of the glue pulling motor 61, the glue pulling slide carriage 62 is driven to slide and reset towards the glue pressing mechanism 40, and the pressure distribution shaft 67 rolls the gummed paper 200 adsorbed to the first rolling surface 71a in the process of sliding and resetting along with the glue pulling slide carriage 62; after rolling is finished, the first air cylinder 63 drives the pressure distribution shaft 67 to reset, and simultaneously, the second air cylinder 64 drives the pressure distribution block 66 to slide to a pressure distribution position aligned with the pressure distribution shaft 67 so as to prepare for next glue drawing; meanwhile, the rotary driver 72 drives the first roll-on surface 71a to move away from the glue preparation station and rotates the second roll-on surface 71b to the glue preparation station, and the first roll-on surface 71a transfers and attaches the adhesive paper 200 adsorbed by the first roll-on surface to the pole piece due to the loss of vacuum in the process of moving away from the glue preparation station, and accordingly, the glue preparation process of the second roll-on surface 71b is the same as that of the first roll-on surface 71a, and therefore, the description is omitted here.

Compared with the prior art, as the side surface of the rolling shaft 71 is provided with the first rolling surface 71a and the second rolling surface 71b which are separated from each other along the circumferential direction of the rolling shaft 71, the interior of the rolling shaft 71 is provided with the first vacuum channel 71c and the second vacuum channel 71d which are not communicated with each other, and the inlets of the first vacuum channel 71c and the second vacuum channel 71d are respectively used for being communicated with an external vacuum generating device so as to independently control the first vacuum channel 71c and the second vacuum channel 71 d; the outlet 712 of the first vacuum channel 71c is located on the first roll-on face 71a and the outlet 714 of the second vacuum channel 71d is located on the second roll-on face 71 b; therefore, the first rolling surface 71a and the second rolling surface 71b are switched regularly at the glue preparation station, so that one of the first rolling surface 71a and the second rolling surface 71b is in glue preparation while the other is in glue pasting, the glue preparation and the glue pasting are carried out synchronously without mutual interference, waiting time is not needed, and the pole piece glue pasting efficiency is improved.

The above disclosure is only a preferred embodiment of the present invention, which is convenient for those skilled in the art to understand and implement, and certainly not to limit the scope of the present invention, therefore, the present invention is not limited by the claims and their equivalents.
