[0046] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0047] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0048] In the following embodiments, reference is made to Figures 1 to 15 , the direction indicated by the X-axis arrow is right, the direction indicated by the Y-axis arrow is front, and the direction indicated by the Z-axis arrow is up.

[0049] Embodiment 1:

[0050] like Figures 1 to 6As shown, in this embodiment, a device 10 for cutting, tracing and pasting a pole piece is provided, comprising: a plate body 100 and two adhesive preparation mechanisms 200 for preparing adhesive tape, two suction mechanisms 300 for absorbing adhesive tape and pasting the adhesive tape to the pole piece 700, a rear clamping mechanism 600, a cutting mechanism 500 and a front clamping mechanism 400 for cutting the pole piece 700 at the cutting position, which are sequentially connected to the plate body 100 along the conveying direction of the pole piece 700; the two adhesive preparation mechanisms 200 and the two suction mechanisms 300 are arranged at intervals on both sides of the pole piece 700, and the plate body 100 is connected with two suction mechanisms 300 for driving a suction mechanism 300 to accelerate to A chasing driver 110 with the same speed as the pole piece 700, a chasing clamping driver 130 and a chasing cutting driver 120 for driving the cutting mechanism 500 to accelerate to the same speed as the pole piece 700 and decelerate after the pole piece 700 is cut and then accelerate to move the broken end of the pole piece 700 forward. The output end of each chasing driver 110 is connected to a suction mechanism 300, the output end of the chasing cutting driver 120 is connected to the cutting mechanism 500, the front clamping mechanism 400 and the rear clamping mechanism 600 are connected to the mounting plate 140, and the output end of the chasing clamping driver 130 is connected to the mounting plate 140, so that the chasing clamping driver 130 drives the mounting plate 140 to accelerate to the same speed as the pole piece 700.

[0051] Specifically, the plate body 100 is installed vertically, and the installation direction is along the plane formed by the Y axis and the Z axis, and an opening is opened on the surface of the plate body 100 that runs through its left and right sides. The pole piece 700 is transported from back to front along the Y axis direction, wherein, by placing the pole piece 700 horizontally, the problem of the pole piece 700 hanging and sagging can be reduced. And two glue preparation mechanisms 200, two suction mechanisms 300, front clamping mechanism 400, cutting mechanism 500 and rear clamping mechanism 600 are installed on the plate body 100 from back to front in sequence, and the working ends are all arranged on the right side of the plate body 100. The glue preparation mechanism 200 is used for independent glue preparation. The two glue preparation mechanisms 200 are installed on the plate body 100 and are arranged perpendicular to each other with the plane where the plate body 100 is located. Along the plane formed by the X axis and the Z axis, the pole piece 700 passes between the two glue preparation mechanisms 200, that is, the two glue preparation mechanisms 200 are arranged on the upper and lower sides of the pole piece 700. The pole piece 700 passes through between the two suction mechanisms 300, that is, the two suction mechanisms 300 are arranged on the upper and lower sides of the pole piece 700, and the two chasing drivers 110 are respectively connected to the plate body 100 through the base body, and are arranged at intervals up and down, so that the two suction mechanisms 300 slide on the plate body 100, so that the two suction mechanisms 300 are synchronized with the transmission speed of the pole piece 700 under the driving action to carry out chasing. The two suction mechanisms 300 keep a distance from the pole piece 700 under normal conditions. When working, the two suction mechanisms 300 vacuum absorb the prepared adhesive tape and approach the pole piece 700 when gluing to attach the absorbed adhesive tape to one side of the pole piece 700. The front clamping mechanism 400 and the rear clamping mechanism 600 normally maintain a distance from the upper and lower surfaces of the pole piece 700. When working, the front clamping mechanism 400 and the rear clamping mechanism 600 respectively clamp the front and rear ends of the pole piece 700. The chase clamping driver 130 is installed on the left side of the plate body 100 through the base body, and the output end of the chase clamping driver 130 is connected to the mounting plate 140 through the opening, so that the mounting plate 140 slides on the right side of the plate body 100 in cooperation with the slide rail slider, so that the front clamping mechanism 400 and the rear clamping mechanism 600 slide on the plate body 100 under the driving action of the chase clamping driver 130 until they are synchronized with the transmission speed of the pole piece 700 for chase clamping. The cutting mechanism 500 normally maintains a distance from the upper and lower surfaces of the pole piece 700. When the pole piece 700 reaches the cutting position, the cutting mechanism 500 approaches and cuts the pole piece 700. The follow-up cutting driver 120 is installed on the left side of the plate body 100 through the seat body, and the output end of the follow-up cutting driver 120 is connected to the cutting mechanism 500 through the opening, so that the cutting mechanism 500 slides on the right side of the plate body 100 under the driving action of the follow-up cutting driver 120 until it is synchronized with the transmission speed of the pole piece 700 for follow-up cutting. The front clamping mechanism 400, the cutting mechanism 500 and the rear clamping mechanism 600 are arranged at intervals in front and back.

[0052] It is worth noting that after the glue preparation mechanism 200 completes the glue preparation, the suction mechanism 300 takes away the adhesive tape for standby use. After the external sensor detects that the pole piece 700 is transmitted to a cuttable length, the two chasing drivers 110 drive the corresponding suction mechanisms 300, the chasing driver 120 drives the cutting mechanism 500 to move along the transmission direction of the pole piece 700, and the chasing driver 130 drives the front clamping mechanism 400 and the rear clamping mechanism 600 to move along the transmission direction of the pole piece 700. When the moving speeds of the front clamping mechanism 400 and the rear clamping mechanism 600 are synchronized with the transmission speed of the pole piece 700, as shown in FIG. Fig.12 As shown, the front clamping mechanism 400 and the rear clamping mechanism 600 clamp the pole piece 700. At the same time, the operating speeds of the two suction mechanisms 300 and the cutting mechanism 500 are synchronized with the transmission speed of the pole piece 700. Fig.13 As shown, the cutting mechanism 500 reaches the cutting position of the pole piece 700 and cuts off the pole piece 700. After that, the follow-up cutting driver 120 drives the cutting mechanism 500 to first decelerate and then accelerate until the running speed of the cutting mechanism 500 is accelerated again to synchronize with the transmission speed of the pole piece 700. At this time, the fracture of the pole piece 700 is located in front of the cutting mechanism 500. After that, as shown in FIG. Fig.14 As shown, the external mechanism drives the two front clamping assemblies 420 clamping the pole piece 700 to move forward, so that the cut pole piece 700 is pulled away to a set distance. At the same time, the two suction mechanisms 300 and the cutting mechanism 500 arrive at the gluing position, and the vertical line at the fracture of the pole piece 700 is located in the middle of the two suction mechanisms 300, as shown in FIG. Fig.15 As shown, the two suction mechanisms 300 stick adhesive tape to the fracture of the pole piece 700. At this time, the two suction mechanisms 300 are evacuated and no longer absorb the adhesive tape. After the two suction mechanisms 300 are glued, they withdraw from the pole piece, thereby completing the chasing and pasting of the pole piece 700. After the gluing is completed, the front clamping mechanism 400 and the rear clamping mechanism 600 release the pole piece 700 to reset, the pole piece 700 continues to run, and the cutting mechanism 500 and the two suction mechanisms 300 are reset. In this way, the pole piece 700 can be transported throughout the whole process without stopping, so that the cutting and gluing process can be completed faster. Among them, by separately providing a chasing and pasting driver 110, the pole piece can also directly complete the chasing and pasting under normal conditions.

[0053] Embodiment 2:

[0054] This embodiment is a further implementation of embodiment 1. Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in some embodiments, the front clamping mechanism 400 includes two front clamping assemblies 420, a front pulling driver 410 and a front slide 411 arranged on both sides of the pole piece 700, the front pulling driver 410 is installed on the mounting plate 140, the output end of the front pulling driver 410 is connected to the front slide 411, and the front clamping assembly 420 is connected to the front slide 411 so that the front slide 411 is slidably set on the mounting plate 140.

[0055] Specifically, the front pull driver 410 is installed on the mounting plate 140 through a seat, the front slide plate 411 and the mounting plate 140 are arranged perpendicular to each other, and the front pull driver 410 drives the front slide plate 411 to slide on the mounting plate 140, and the front slide plate 411 slides on the mounting plate 140 along the Y-axis direction by cooperating with the slide rail and the slider, so as to drive the two front clamping assemblies 420 to slide on the mounting plate 140. Fig.14 The front pulling driver 410 drives the two front clamping assemblies 420 to move, so that the cut pole piece 700 is pulled away to a set distance.

[0056] To facilitate the use of the two front clamping assemblies 420, as Figure 6 As shown, in some embodiments, the front clamping assembly 420 includes a clamping driver 421, a roller frame 422 and a plurality of rollers 423, the clamping driver 421 is connected to the front slide 411, the output end of the clamping driver 421 is connected to the roller frame 422, and the plurality of rollers 423 are rotatably arranged on the roller frame 422 so that the rollers 423 on both sides are close to or away from each other.

[0057] Specifically, two clamping drivers 421 are connected to the upper and lower sides of the front slide plate 411, and the two clamping drivers 421 respectively drive the corresponding roller frames 422 to approach the pole piece 700, so as to clamp the pole piece through the corresponding rollers 423. The number of rollers 423 is set to two. In another embodiment, the number of rollers 423 can be set to three. In another embodiment, the number of rollers 423 can be set to four. When the front clamping mechanism 400 clamps the front end of the pole piece 700, the rolling rollers 423 contact the pole piece 700. When the pole piece 700 is clamped, the contact area with the pole piece 700 can be effectively reduced compared with the clamping plate, thereby reducing the degree of damage to the pole piece 700.

[0058] In order to facilitate the practicality of the front clamping mechanism 400, as Figures 4 to 6As shown, in some embodiments, two cam platforms 150 are installed on the plate body 100, and two cam grooves 151 are opened on the cam platform 150. The front clamping mechanism 400 also includes two front sliders 430, two front guide rods 440 and two front cam followers 450. The two front sliders 430 are slidably set on the front slider 411, and each clamping driver 421 is connected to a front slider 430, and each front guide rod 440 is connected to a front slider 430. One end of each front cam follower 450 is connected to a front guide rod 440, and the other end is slidably set in a cam groove 151 to drive the rollers 423 on both sides to approach or move away from each other.

[0059] Specifically, in the initial state, the two clamping drivers 421 drive the rollers 423 on the upper and lower sides of the pole piece 700 to be in a clamping state. Two cam platforms 150 are installed on the upper and lower sides of the pole piece 700, and two cam grooves 151 are provided on the right side of the cam platform 150 along the Y-axis direction. Two front sliders 430 are slidably arranged on the rear end face of the front slider 411 by matching the slide rail sliders, and they slide along the Z-axis direction. Each front clamping assembly 420 is installed on the rear end face of a front slider 430. The front guide rod 440 and the front slider 430 are arranged perpendicular to each other, and one end of the front guide rod 440 away from the front cam follower 450 is fixedly connected to the front slider 430, the right end of the front cam follower 450 is fixed on the front guide rod 440, and the left end is slidably arranged in the corresponding cam groove 151, and the front cam follower 450 matches the cam groove 151. When the chase clamping driver 130 is driven, the mounting plate 140 slides along the conveying direction of the pole piece 700, and the front slide plate 411 slidingly arranged on the mounting plate 140 moves accordingly along the conveying direction of the pole piece 700, and the two front slide blocks 430 slidingly arranged on the front slide plate 411 also move accordingly. When the front slide block 430 moves, the front cam follower 450 moves along the path of the cam slot 151, and the path of the cam slot 151 is correspondingly arranged to drive the rollers 423 on both sides to clamp or release the pole piece 700 in the corresponding area. Through the cooperation between the front cam follower 450 and the cam slot 151, the starting time of the driving action of the clamping driver 421 is reduced, driving the two front clamping components 420 to clamp or release the pole piece 700 faster. It can be understood that the path of the cam slot 151 is set accordingly to drive the front cam follower 450 to change its displacement when the pole piece 700 needs to be clamped or loosened. This is known to those skilled in the art and is achievable, and is not described in detail in this embodiment.

[0060] In order to increase the practicality of the rear clamping mechanism 600, as Figures 4 to 7As shown, in some embodiments, the rear clamping mechanism 600 includes two rear drivers and two rear clamping plates 620 for clamping the pole piece 700, the two rear drivers are connected to the mounting plate 140, and the output end of each rear driver is connected to a rear clamping plate 620 so that the two rear clamping plates 620 are moved closer to or away from each other.

[0061] Specifically, two rear clamping plates 620 are disposed on the upper and lower sides of the pole piece 700, and the rear driver is disposed on the mounting plate 140 through a plate body, so that the pole piece 700 can be clamped.

[0062] In order to facilitate the rear clamping mechanism 600 to quickly clamp the pole piece 700, as shown in FIG. Figures 4 to 7 As shown, in some embodiments, the rear clamping mechanism 600 also includes two rear cam followers 610, each rear cam follower 610 is connected to a rear clamping plate 620, and each rear cam follower 610 is slidably disposed in a cam groove 151 to enable the two rear clamping plates 620 to move closer to or away from each other.

[0063] Specifically, in the initial state, the two rear drivers drive the two rear clamping plates 620 to always be in a clamping trend.
