Detailed Implementation

[0029] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0030] The winding-off integrated deviation rectifying and guiding device provided by the embodiments of the present application comprises two groups of winding-off devices and one group of deviation rectifying devices, as shown in the accompanying drawings Figure 1 The one group of deviation rectifying devices is arranged between the two groups of winding-off devices, and comprises a connecting piece, one end of the one group of deviation rectifying devices is connected with one of the two groups of winding-off devices, the other end of the one group of deviation rectifying devices is connected with the other of the two groups of winding-off devices, and the connecting piece of the one group of deviation rectifying devices is switched to be connected, so that the one group of deviation rectifying devices is connected with one or the other of the two groups of winding-off devices for use. The two groups of winding-off devices can share one group of deviation rectifying devices, and each group of winding-off devices does not need to be equipped with a corresponding deviation rectifying device, which can reduce the configuration of the number of deviation rectifying and guiding rollers and related workpieces, improve the assembly efficiency when the system is assembled, and is more convenient to maintain. The number of deviation rectifying and guiding rollers is reduced, the manufacturing cost of the equipment is reduced, and the space utilization is improved.

[0031] The two sets of unwinding devices are unwinding device one 11 and unwinding device two 12, and the structures of unwinding device one 11 and unwinding device two 12 are the same. Here, unwinding device one 11 is taken as an example to specifically illustrate the structure of the unwinding device. Unwinding device one 11 comprises a support table 111, a deviation correction servo motor 112, an air expansion shaft 113, an unwinding servo motor 114 and a roll material 115. An upper support plate 116 is slidably arranged on the support table 111. The support table 111 is also provided with the deviation correction servo motor 112, which drives the upper support plate 116 to slide. Two support blocks 117 are fixed on the upper support plate 116. A rotating shaft 118 is supported between the two support blocks 117. One end of the rotating shaft 118 penetrates one of the support blocks 117 and is connected with the unwinding servo motor 114. The other end of the rotating shaft 118 penetrates the other support block 117 and is connected with one end of the air expansion shaft 113. The other end of the air expansion shaft 113 is connected with the roll material 115. Further, the unwinding servo motor 114 is fixed on the upper support plate 116 through a fixed support 119. A transmission belt 120 is arranged between the unwinding servo motor 114 and the rotating shaft 118. The transmission belt 120 is sleeved on two transmission wheels arranged in an up-down manner. The two transmission wheels comprise an upper transmission wheel and a lower transmission wheel. The upper transmission wheel is in transmission connection with the driving shaft of the unwinding servo motor 114. The lower transmission wheel is in transmission connection with the rotating shaft 118. Thus, when the unwinding servo motor 114 works, the rotating shaft 118 is driven to rotate through the transmission belt 120. In turn, the rotating shaft 118 drives the roll material 115 to rotate, and the pole piece material belt 125 on the roll material 115 is unwound.

[0032] Referring to the accompanying drawings Figure 2 The sliding connection mode of the deviation correction servo motor 112 and the upper support plate 116 is as follows. The support table 111 is provided with a deviation correction servo motor and a screw rod fixing seat 122. The screw rod fixing seat 122 is fixedly connected with the support table 111. The driving shaft end of the deviation correction servo motor 112 is connected with one end of a ball screw rod 121 through a coupling. The ball screw rod 121 is rotatably supported in the screw rod fixing seat 122. The other end of the ball screw rod 121 penetrates a screw rod connecting block 123. The ball screw rod 121 is in threaded connection with the screw rod connecting block 123. The screw rod connecting block 123 is fixedly connected with the upper support plate 116. Thus, when the deviation correction servo motor rotates, the ball screw rod 121 on the screw rod fixing seat 122 is driven to rotate through the coupling. The rotating ball screw rod 121 drives the screw rod connecting block 123 in threaded connection therewith to move back and forth, and in turn, the screw rod connecting block 123 drives the upper support plate 116 to move back and forth to correct deviation in the front and back directions (i.e. deviation correction in the X-axis direction). Preferably, the screw rod connecting block 123 is arranged on a linear guide rail 124. The screw rod connecting block 123 can move back and forth along the linear guide rail 124, thereby ensuring the stability of movement.

[0033] Specifically, refer to the attached drawings Figures 2-7 A set of deviation rectifying devices 2 includes a deviation rectifying over roller 22 and a connecting piece 21, wherein the connecting piece 21 includes a deviation rectifying connecting plate 24 and two jacking cylinders; the deviation rectifying over roller 22 and the connecting piece 21 are connected, and more preferably, the deviation rectifying over roller 22 is connected with an over roller connecting plate 23, and the over roller connecting plate 23 is fixedly connected with the deviation rectifying connecting plate 24. Wherein the deviation rectifying connecting plate 24 is inverted T-shaped, wherein the vertical part of the inverted T-shaped is fixed with the over roller connecting plate 23, and the fixing mode is screw connection, welding, riveting and other commonly used connection modes; the horizontal part of the inverted T-shaped is connected with one jacking cylinder at each end, and two positioning pin grooves are further provided on the horizontal part of the inverted T-shaped, and the two positioning pin grooves are respectively arranged at the two ends of the horizontal part of the inverted T-shaped; the two jacking cylinders are respectively arranged on two sets of unwinding devices, specifically, the two jacking cylinders are jacking cylinder one 25 and jacking cylinder two, and the two positioning pin grooves are positioning pin groove one 26 and positioning pin groove two, jacking cylinder one 25 cooperates with positioning pin groove one 26, the cylinder part of jacking cylinder one 25 is fixedly connected on the upper layer support plate 116 of unwinding device one 11, a positioning pin one 27 is connected on the pneumatic rod of jacking cylinder one 25, the positioning pin one 27 is matched with the positioning pin groove one 26 on the horizontal part of the inverted T-shaped, and the lifting action of the pneumatic rod of jacking cylinder one 25 makes the positioning pin one 27 cooperate with or separate from the positioning pin groove one 26; correspondingly, jacking cylinder two cooperates with positioning pin groove two, the cylinder part of jacking cylinder two is fixedly connected on the upper layer support plate of unwinding device two 12, the positioning pin two connected on the pneumatic rod of jacking cylinder two is matched with the positioning pin groove two on the horizontal part of the inverted T-shaped, and the lifting action of the pneumatic rod of jacking cylinder two makes the positioning pin two cooperate with or separate from the positioning pin groove two. Through the lifting of the jacking cylinder, the positioning pin on the jacking cylinder cooperates with or separates from the positioning pin groove on the deviation rectifying connecting plate, the connection or separation of the unwinding device and the deviation rectifying device is completed, the switching is convenient, easy to operate and implement, and the flexibility is high.

[0034] Further, a manual displacement table 31 is arranged on one side of any deviation rectifying over roller 22 close to the winding material, and a light barrier photoelectric sensor 32 is arranged on the manual displacement table 31, the light barrier photoelectric sensor 32 is arranged on one side of the pole piece material belt 125, and the unwound pole piece material belt 125 passes through the light barrier photoelectric sensor 32 horizontally after passing through the deviation rectifying over roller 22, the light barrier photoelectric sensor 32 senses the position of the pole piece material belt 125 and feeds back the position of the pole piece material belt 125 to the deviation rectifying servo motor, and the manual displacement table 31 can adjust the position of the displacement table to adapt to pole pieces of various sizes.

[0035] During operation, when the coil 115 on the unwinding device 11 is unwound, the lifting cylinder 25 fixed on the unwinding device 11 is inserted into the positioning pin groove 26, connecting the correction device 2 to the unwinding device 11. The unwinding servo motor 114 of the unwinding device 11 drives the air shaft 113 to drive the correction roller 22 to unwind the material. At the same time, the through-beam photoelectric sensor 32 detects the front and rear positions of the electrode and feeds back to the correction servo motor 112 of the unwinding device 11 to guide the electrode. The sheet is corrected by the correction servo motor 112 driving the upper support plate 116 to slide. The upper support plate 116 drives the unwinding device 11, the roll 115, and the correction device 2, which are fixedly connected to it, to move back and forth, changing the front and back position of the electrode strip 125, thus correcting the roll 115 of the unwinding device 11. After the roll 115 on the unwinding device 11 is unwound, the lifting cylinder 25 exits the positioning pin groove 26, causing the correction device 2 to disengage from the unwinding device 11. Similarly, when the roll on the unwinding device 2 12 is unwound, the lifting cylinder 2 fixed on the unwinding device 2 12 is inserted into the positioning pin groove 2, so that the correction device 2 is connected to the unwinding device 2 12. The above steps are repeated to perform unwinding and correction of the roll on the unwinding device 2 12.

[0036] Furthermore, the correction device 2 includes a roller support shaft 28, a linear bearing 29, a correction roller 22, and an electrode smoothing sheet metal 30. One end of the roller support shaft 28 is fixedly connected to the roller connecting plate 23. The linear bearing 29 and the correction roller 22 are arranged sequentially on the roller support shaft 28, with the linear bearing close to the roller connecting plate 23. The other end of the roller support shaft 28 is connected to the electrode smoothing sheet metal 30, which is positioned above the correction roller 22. A large unwinding plate 33 is provided between the roller connecting plate 23 and the correction roller 22. The linear bearing 29 passes through the large unwinding plate 33, and one end of the linear bearing 29 is fixed to the large unwinding plate 33 by a fixed flange. The roller support shaft 28 passes through the linear bearing 29, and the roller support shaft 28 and the linear bearing 29 are in sliding fit. The through-beam photoelectric sensor 32 and the electrode smoothing sheet metal 30 are respectively located on both sides of the electrode strip 125.

[0037] During the correction adjustment, the sensor detects the position of the material strip and feeds back to the correction servo motor 112. The correction servo motor 112 drives the coil 115 and the roller connecting plate 23 to move back and forth. Under the guidance of the linear bearing 29, the roller support shaft 28 moves back and forth along the linear bearing 29, so that the roller support shaft 28 drives the correction roller 22 to move to correct the material strip back and forth.

[0038] Preferably, three over-roller support shafts 28 are provided, two over-roller support shafts are arranged side by side on the upper end of the over-roller connecting plate 23 in the horizontal plane, and one over-roller support shaft is arranged on the lower end of the over-roller connecting plate 23, and linear bearings, deviation-correcting over-rollers, and pole piece flattening plates 30 are arranged on the three over-roller support shafts. The specific arrangement is the same as described above, and will not be described again. Further, the diameters of the linear bearings and deviation-correcting over-rollers on the lower end of the over-roller connecting plate 23 are greater than the diameters of the linear bearings and deviation-correcting over-rollers on the upper end of the over-roller connecting plate 23. The arrangement of the above-described deviation-correcting device can effectively accommodate two winding material running paths with only three deviation-correcting over-rollers, and can effectively accommodate clockwise winding or counterclockwise winding. Further, the winding material can be kept in a straight line state during the running of the winding material, as shown in FIG. 6. Figures 8-9 The winding material running path on the first winding device 11 and the winding material running path on the second winding device 12 can not only reduce the number of deviation-correcting over-rollers, but also ensure compatibility and keep the winding material in a straight line state, thereby improving detection accuracy and laying a precision foundation for subsequent pole piece cutting.

[0039] Compared with the prior art, two groups of winding devices can share one group of deviation-correcting devices, and each group of winding devices does not need to be equipped with corresponding deviation-correcting devices. This can reduce the number of deviation-correcting guide rollers and related workpieces, improve assembly efficiency during system assembly, and make maintenance more convenient. The number of deviation-correcting guide rollers is reduced, which reduces the manufacturing cost of the equipment and improves the space utilization rate. The winding material can also be kept in a straight line state, which can further improve the detection accuracy and lay a precision foundation for subsequent pole piece cutting.
