Detailed Description

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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1-4, the present application discloses an unwinding mechanism, which includes a material roll 2 for rolling a substrate 1, and a deviation correcting assembly 100 for driving the material roll 2 to move along an axial direction thereof. The base material 1 is wound into a roll and then placed on a supply reel 2. When a new roll is first threaded, the substrate 1 is manually pulled from the reel 2 through downstream equipment (not shown). After the substrate 1 is threaded, the unwinding mechanism is started, and the substrate 1 can be pulled to move forwards actively by matching with downstream equipment.

In order to facilitate the release of the substrate 1, the present application further includes an unwinding assembly 200 for driving the material reel 2 to rotate so as to rotate the material roll, thereby unwinding the substrate 1. Specifically, the unwinding assembly 200 includes an unwinding driving member 210, and in an embodiment, the unwinding driving member 210 is connected to and drives the material reel 2 to rotate, wherein the unwinding driving member 210 is preferably a servo motor. In other embodiments, the unwinding driving member 210 is a magnetic powder brake. At the moment, the base material 1 is pulled by downstream equipment to start to be fed, and the magnetic powder brake can assist in braking the material reel 2, so that the material reel 2 starts to rotate and releases the base material 1; further, the magnetic powder brake can be used for controlling the rotating speed of the material reel 2, so that the tension released by the base material 1 is controlled by matching with the traction of downstream equipment, and the unreeling stability is ensured. After the tape is removed, the magnetic powder brake can stop the material reel 2 and stop the rotation of the material reel 2.

The material roll shaft 2 is preferably an air expansion shaft which can expand a material roll formed by the base materials 1, so that rotary discharging is convenient to realize; after a roll of base material 1 is used up, the air expansion shaft can loosen the material roll, so that the old material roll can be conveniently taken down and replaced by a new material roll.

The substrate 1 can be regarded as an infinitely long rectangle. Therefore, when the deviation of the substrate 1 discharged from the material reel 2 is corrected, the substrate 1 can be driven to move along the direction only by driving the material reel 2 to move along the axial direction, namely the width direction of the infinite rectangle, and then the position of the substrate 1 after the material reel 2 is discharged is adjusted. Since the base material 1 is specifically a regular pattern, the position of the entire base material 1 is substantially fixed as long as the position of the base material 1 in one direction is always adjusted to a certain state.

Specifically, the deviation correcting assembly 100 includes a deviation correcting driving assembly 110 and a deviation correcting guide bearing 120, and the deviation correcting driving assembly 110 is connected to and drives the material reel 2 to move along the deviation correcting guide bearing 120. Wherein, the deviation-correcting guide bearing 120 is a guide member for guiding the material reel 2 to move. Thus, the deviation correcting guide bearing 120 is provided to extend in the axial direction of the reel shaft 2. In order to fix the deviation-rectifying guide bearing 120 and ensure stable installation and high guide precision, the deviation-rectifying guide bearing 120 is arranged between the first mounting plate 3 and the second mounting plate 4, and the first mounting plate 3 and the second mounting plate 4 are oppositely arranged along the axial direction of the material reel 2. The both ends of the guiding bearing 120 of rectifying are fixed to be set up on first mounting panel 3 and second mounting panel 4, and first mounting panel 3 and second mounting panel 4 provide stable mounted position for the guiding bearing 120 of rectifying. Because the material roll formed by the substrate 1 has a certain weight, the material roll 2 can be used for weighting the mass of one end of the substrate 1, so that the end of the material roll 2 has a falling tendency, therefore, when the material roll 2 reciprocates along the deviation-correcting guide bearing 120, the material roll 2 can wear the port of the deviation-correcting guide bearing 120 close to the substrate 1, or the material roll 2 can wear the position of the deviation-correcting guide bearing 120 close to the first mounting plate 3 of the substrate 1 with the deviation-correcting guide bearing 120. In the conventional equipment, only will rectify the direction bearing and pass a mounting panel and fix the setting, this moment, in case the direction bearing or the mounting panel of rectifying is worn and torn, leads to the material spool slope to the length of material spool, when the position of substrate 1, the degree of deviation of substrate 1 has been very big, is unfavorable for rectifying. This application is through setting up the direction bearing that rectifies between first mounting panel 3 and second mounting panel 4, even the position that the direction bearing 120 that rectifies is close to the port of substrate 1 or the direction bearing 120 is rectified in the installation of first mounting panel 3 is worn and torn, because the position of the direction bearing 120 that rectifies is still being injectd to second mounting panel 4, can not influence the axial motion of material spool 2.

More specifically, the material roll 2 sequentially passes through the first mounting plate 3, the deviation-correcting guide bearing 120 and the second mounting plate 4, meanwhile, the material roll 2 passes through one end of the first mounting plate 3 to wind the substrate 1, one end of the material roll 2 passing through the second mounting plate 4 is connected with the deviation-correcting drive assembly 110, and the deviation-correcting drive assembly 110 drives the material roll 2 to move along the deviation-correcting guide bearing 120.

In one embodiment, the unwinding drive 210 is connected to the material reel 2 through one end of the second mounting plate 4 to drive the material reel 2 to rotate and release the substrate 1.

It can be understood that, in the present embodiment, the material roll shaft 2 needs to rotate around its central axis and also needs to move linearly along its axial direction. In order to ensure that the two actions do not interfere with each other, the unwinding assembly 200 further comprises a sleeve 220 sequentially passing through the first mounting plate 3, the deviation-correcting guide bearing 120 and the second mounting plate 4, the material reel 2 is rotatably arranged in the sleeve 220 through a bearing, and one end of the sleeve 220 passing through the second mounting plate 4 is connected with the deviation-correcting drive assembly 110. As shown in fig. 1 or fig. 2, the material reel 2 further passes through the sleeve 220 to be connected to the unwinding driving member 210. Therefore, the deviation-correcting driving assembly 110 drives the sleeve 220, drives the material reel 2 and the unreeling driving member 210 to move along the deviation-correcting guide bearing 120; the unwinding driving unit 210 can independently drive the material reel 2 to rotate in the sleeve 220 without affecting the sleeve 200 and the deviation rectifying guide bearing 120.

In order to facilitate the installation and the driving of the sleeve 220, the deviation correcting driving assembly 110 includes a deviation correcting driving member 111 and a deviation correcting mounting plate 112, and the deviation correcting mounting plate 112 is disposed on the other side of the second mounting plate 4 relative to the first mounting plate 3, that is, the second mounting plate 4 is disposed between the first mounting plate 3 and the deviation correcting mounting plate 112. The sleeve 220 passes through one end of the second mounting plate 4 and is arranged on the deviation-rectifying mounting plate 112, the unreeling driving member 111 is connected with and drives the deviation-rectifying mounting plate 112 to move towards the second mounting plate 4, specifically, the unreeling driving member 111 is connected with and drives the deviation-rectifying mounting plate 112, drives the sleeve 220 to move along the deviation-rectifying guide bearing 120, namely, the material reel 2 axially. The unreeling driving element 111 is preferably a motor and a lead screw arranged at the output end of the motor, the lead screw is arranged in parallel to the axial direction of the material reel 1, the deviation-correcting mounting plate 112 is in threaded connection with the lead screw, therefore, the motor drives the lead screw to rotate, the lead screw converts the rotary motion of the motor into the linear motion of the deviation-correcting mounting plate 112 along the axial direction of the material reel 1, and the deviation-correcting guide bearing 120 further provides guidance and protection for the motion of the material reel 1.

Further, because the material that the material book that substrate 1 constitutes has certain weight, can add the quality of material spool 2 bearing substrate 1 one end for material spool 2 has the trend of tenesmus, and from this, in order to avoid substrate 1 to cross heavy pouring material spool 2, the mounting panel 112 of rectifying deviates from sleeve 220, and one side of just keeping away from substrate 1 is provided with balancing weight 5. Through balancing weight 5 that has a basis weight, can compensate the weight difference at deviation rectification guide bearing 120 both ends to ensure that whole unwinding mechanism's center is in deviation rectification guide bearing 120's length within range, and then improve deviation rectification guide bearing 120's life.

Further, at least one supporting seat 6 is arranged between the first mounting plate 3 and the second mounting plate 4 to fix the relative positions of the first mounting plate 3 and the second mounting plate 4, so that the rigidity of the first mounting plate 3 and the second mounting plate 4 is improved. Through setting up supporting seat 6, inject and strengthened the relative position relation of first mounting panel 3 and second mounting panel 4, and then guarantee that the direction bearing 120 of rectifying is stable, locate between first mounting panel 3 and the second mounting panel 4 along the material spool 2 axial accurately.

For the unwinding mechanism, when a new roll is first threaded, the substrate 1 is manually pulled from the reel shaft 2 through a downstream device (not shown). It should be noted that, the substrate 1 is used as a basic material for preparing a battery cell, and is high in cost and not prone to waste, and therefore, the unwinding mechanism provided by the present application further includes the auxiliary tape transport assembly 300. The auxiliary deck assembly 300 includes an auxiliary supply spool 310 and a reel change assembly 320. The auxiliary material reel 310 is used for winding the auxiliary material 7. It should be noted that the auxiliary material 7 is a common material different from the standard base material 1, but having a specification (mainly referring to the width extending along the axial direction of the material reel 1) similar to that of the standard base material 1, such as white paper or common foil. The auxiliary material 7 is wound into a roll and then placed on the auxiliary material reel 310.

In this application, the auxiliary material reel 310 is used to take up and release a roll of auxiliary material 7. Therefore, the auxiliary material reel 310 is preferably an inflatable shaft which can expand the material roll formed by the auxiliary material 7, so that the rotary discharging is convenient to realize; after a roll of auxiliary material 7 is used up, the air expansion shaft can release the material roll, so that the old material roll can be conveniently taken down and replaced by a new material roll. Meanwhile, the auxiliary tape deck 300 further includes an auxiliary unwinding driving member 311, and the auxiliary unwinding driving member 311 is connected to the auxiliary material reel 310 to assist the auxiliary material reel 310 to release the auxiliary material 7. The auxiliary unwinding driving member 311 is similar to the unwinding driving member 210, and is not described herein again.

Specifically, when the equipment is used for the first time, the base material 1 needs to be threaded manually and wound through each piece of downstream equipment, so that each piece of downstream equipment can conveniently process the base material 1. Before threading the base material 1, the auxiliary material 7 on the auxiliary material reel 310 is manually pulled out through the downstream equipment to ensure that the auxiliary material 7 is completely threaded. The substrate 1 is then attached by the reel change assembly 320 behind the secondary material 7 entering the downstream equipment. Therefore, after the device is started, the downstream device is matched with the unwinding mechanism to pull the pulled auxiliary material 7 to move forwards, the pulled auxiliary material 7 further drives the base material 1 connected behind the pulled auxiliary material to enter the downstream device, and therefore the base material 1 is actively and accurately conveyed through the device. By arranging the auxiliary tape transport assembly 300, on one hand, the fault-tolerant rate of manual tape transport is improved, and the waste of the base material 1 caused by misoperation of directly transporting the base material 1 by manual work is avoided; on the other hand, after the auxiliary material 7 enters downstream equipment, the equipment is started first, and the matching rhythm or the installation position of each equipment is reversely adjusted according to the treatment effect of the auxiliary material 7, so that the waste of the base material 1 caused by debugging the base material 1 is avoided.

In one embodiment, the unwinding mechanism of the present application is applied to a slitting machine. At this time, the downstream apparatus is used to slit the base material 1 into a plurality of strips in the width direction thereof. In this embodiment, in addition to the need for pre-threading of the secondary material 7 for the first pass, the base substrate 1 is processed at downstream equipment and slit into multiple narrow strips, each of which is eventually rewound into a narrow roll, and each narrow roll also requires the secondary material 7 to be terminated and wrapped around the circumference of the narrow roll by the secondary material 7 to protect the portion of the base substrate 1 within the narrow roll. That is, when the substrate 1 on the reel shaft 2 is about to be processed, the apparatus is stopped, and the substrate 1 is replaced with the auxiliary material 7 by the reel changer 320. Subsequently, the apparatus is started again, and the substrate 1 in the downstream apparatus pulls the auxiliary material 7 actively forward until the auxiliary material 7 is also processed to a specification in conformity with the substrate 1 and finally wound around the outer circumference of the narrow roll.

Since the reel change assembly 320 is used to replace the base material 1 and the auxiliary material 7, so that the auxiliary material 7 actively pulls the base material 1 into the downstream equipment, or further so that the base material 1 actively pulls the auxiliary material 7 into the downstream equipment, the reel change assembly 320 is provided at the discharge ends of the material reel 2 and the auxiliary material reel 310, and the base material 1 or the auxiliary material 7 passes through the reel change assembly 320 and enters the downstream equipment.

Specifically, the roll changing assembly 320 includes a roll changing platform 321, a first pressing member 322, a first pressing driving member 323 for driving the first pressing member 322 to approach or move away from the roll changing platform 321, a second pressing member 324, and a second pressing driving member 325 for driving the second pressing member 324 to approach or move away from the roll changing platform 321, and when the substrate 1 or the auxiliary material 7 passes through the roll changing assembly 320, the substrate 1 or the auxiliary material 7 passes through the first pressing member 322 and the roll changing platform 321, and the second pressing member and the roll changing platform 321 in sequence. Meanwhile, a cutting member 326 and a cutting driving member 327 for driving the cutting member 326 to cut the base material 1 or the auxiliary material 7 passing through the roll changing assembly 320 are disposed between the first pressing member 322 and the second pressing member 324.

In one embodiment, as shown in fig. 1 to 3, the first pressing member 322 and the second pressing member 324 are preferably pressing blocks disposed along the axial direction of the material spool, and in the initial state, the first pressing member 322 and the second pressing member 324 are located above the roll changing platform 321. In the initial state, the substrate 1 or the auxiliary material 7 passes over the roll-changing platform 321, and the first pressing member 322 and the second pressing member 324 are suspended above the substrate 1 or the auxiliary material 7. When roll change is required, the first pressing and holding driving member 323 and the second pressing and holding driving member 325 respectively drive the first pressing and holding member 322 and the second pressing and holding member 324 to move towards the roll changing platform 321, so as to press the substrate 1 or the auxiliary material 7 on the roll changing platform 321. Subsequently, the cutting driving member 327 drives the cutting member 326 to move toward the base material 1 or the auxiliary material 7 on the reel-changing table 321, and cuts the base material 1 or the auxiliary material 7. After cutting, the base material 1 or the auxiliary material 7 on the reel-changing platform 321 is divided into a material roll portion of the connecting material reel 2 or the auxiliary material reel 310 which is pressed between the first pressing and holding member 322 and the reel-changing platform 321, and a material cut portion which is pressed between the second pressing and holding member 324 and the reel-changing platform 321 and enters into the downstream equipment. Subsequently, the first pressing and holding driving member 323 drives the first pressing and holding member 322 to move away from the reel changing platform 321, so that the first pressing and holding member 322 releases the base material 1 or the auxiliary material 7 of the reel portion, thereby facilitating the manual removal of the reel portion, and the auxiliary material 7 or the base material 1 to be connected to the cut portion is passed between the first pressing and holding member 322 and the reel changing platform 321 and bonded to the base material 1 or the auxiliary material 7 of the cut portion. After bonding, the second pressing driving member 325 drives the second pressing member 324 away from the reel changing platform 321, and the material breaking portion is released. The equipment is started, and the material breaking part is pulled by downstream equipment to move forwards, so that the auxiliary material 7 or the base material 1 which is adhered to the material breaking part is further driven to enter the downstream equipment.

In this embodiment, the first and second pressure-holding driving members 323 and 325 are preferably air cylinders. When the first pressing and holding member 322 and the second pressing and holding member 324 are located above the roll changing platform 321, the first pressing and holding driving member 323 and the second pressing and holding driving member 325 may be located above the roll changing platform 321, and drive the first pressing and holding member 322 and the second pressing and holding member 324 to move toward the roll changing platform 321 from top to bottom. Alternatively, the first pressing driving member 323 and the second pressing driving member 325 may be disposed below the roll-changing platform 321, and the output end thereof passes through the roll-changing platform 321 to connect the first pressing member 322 and the second pressing member 324.

The cutting member 326 is preferably a cutter disposed along the axial direction of the reel shaft 2 and longer than the width of the auxiliary material 7 or the base material 1, and the cutting driving member 327 is preferably a cylinder. The cutting member 326 is preferably disposed below the roll-changing platform 321 for facilitating manual threading, and the cutting driving member 327 is also disposed below the roll-changing platform 321. When cutting is required, the cutting driving member 327 drives the cutting member 326 to move up and pass through the reel changing platform 321, and cuts the base material 1 or the auxiliary material 7 on the reel changing platform 321. Alternatively, the cutting member 326 passes through the reel changing platform 321, the cutting edge of the cutting member protrudes from the reel changing platform 321, and the cutting driving member 327 is connected to and drives the cutting member 326 to move along the axial direction of the material reel 2, that is, the width direction of the base material 1 or the auxiliary material 7, so as to cut the base material 1 or the auxiliary material 7.

Take the example of a pre-threaded band of auxiliary material 7. After the auxiliary material 7 is manually pulled out from the auxiliary material reel 310, the auxiliary material 7 firstly passes through the first pressing and holding member 322, the second pressing and holding member 324 and the upper part of the reel changing platform 321, and then enters the downstream equipment, so as to complete threading. After threading and debugging are finished, the apparatus is stopped after the apparatus is confirmed to be capable of accurately processing the substrate 1, and the first pressing and holding driving member 323 and the second pressing and holding driving member 325 respectively drive the first pressing and holding member 322 and the second pressing and holding member 324 to move towards the roll changing platform 321, so as to press the auxiliary material 7 on the roll changing platform 321. Subsequently, the cutting drive 327 drives the cutting member 326 toward the auxiliary material 7 on the reel changing table 321, cutting off the auxiliary material 7. After cutting, the cutting driving member 327 drives the cutting member 326 away from the auxiliary material 7 on the reel changing table 321. At this time, the auxiliary material 7 on the change platform 321 is divided into a material roll portion which is compressed between the first holding member 322 and the change platform 321 and connects the auxiliary material roll shaft 310, and a material cut portion which is compressed between the second holding member 324 and the change platform 321 and enters into the downstream equipment. Subsequently, the first holding-down driving member 323 drives the first holding-down member 322 away from the reel change platform 321, so that the first holding-down member 322 releases the auxiliary material 7 of the reel portion to facilitate manual removal of the reel portion, and pulls the base material 1 to be attached to the cut portion out of the reel spool 2, through the first holding-down member 322 and the reel change platform 321, and adheres to the cut portion of the auxiliary material 7. After bonding, the second pressing driving member 325 drives the second pressing member 324 away from the reel changing platform 321, and the material breaking portion is released. Starting the equipment, enabling the material reel 2 to rotate, and releasing the base material 1; the material cutting part is pulled and moves forwards by downstream equipment; thereby, the base material 1 is pulled by the auxiliary material 7 of the blanking portion, and enters the downstream equipment.

Further, in order to facilitate the substrate 1 or the auxiliary material 7 to be transported, the material discharging end of the material winding shaft 2 and/or the auxiliary material winding shaft 310 is provided with a guide roller 330, and the substrate 1 or the auxiliary material 7 is wound around the guide roller 330, enters the roll changing assembly 320, and then enters the downstream equipment. The guide roller 330 has guiding and avoiding functions, on one hand, the base material 1 or the auxiliary material 7 can be guided to move towards the roll changing assembly 320, and the base material 1 or the auxiliary material 7 is prevented from being folded or interfering with other equipment; on the other hand, the auxiliary material has certain tensioning effect, so that the base material 1 or the auxiliary material 7 can be conveniently and stably walked.

Further, as shown in fig. 3, in order to ensure that the roll changing assembly 320 stably supports the substrate 1 or the auxiliary material 7 and realize cutting and receiving, a first adjusting roller 340 is disposed at the discharging end of the material reel 2 and the auxiliary unwinding shaft 310, the substrate 1 or the auxiliary material 7 enters the roll changing assembly 320 after passing through the first adjusting roller 340, and a second adjusting roller 350 is disposed downstream of the roll changing assembly 320. The roller surfaces of the first aligning roller 340 and the second aligning roller 350 for receiving the substrate 1 or the auxiliary material 7 are higher than the roller surfaces of the reel changing assembly 320 for receiving the substrate 1 or the auxiliary material 7. Thus, the base material 1 or the auxiliary material 7 between the first aligning roller 340, the reel change assembly 320 and the second aligning roller 350 is tensioned by the first aligning roller 340 and the second aligning roller 350, is in a straight line, and is suspended above the reel change table 321 and below the first pressing member 322 and the second pressing member 324. This prevents the base material 1 or the auxiliary material 7 from rubbing against the reel changing table 321 during running, thereby preventing the running from being affected and the appearance of the base material 1 or the auxiliary material 7 from being affected. It will be appreciated that the base material 1 or the auxiliary material 7 has a wrap angle on the first and second set rollers 340 and 350, and the first and second set rollers 340 and 350 can cooperate to tension the base material 1 or the auxiliary material 7 for ease of tape-feeding and reel-changing. Further, the first adjusting roller 340 can stably guide the base material 1 or the auxiliary material 7 into the reel-changing assembly 320, so as to prevent the base material 1 or the auxiliary material 7 from being worn by the corners of the reel-changing platform 321 when directly entering the reel-changing assembly 320.

Further, referring to fig. 1-2, the first steering roller 340 is provided with a first steering assembly 360 at one end and a second steering assembly 370 at the other end in the axial direction thereof. The first adjusting assembly 360 includes a first adjusting base 361 extending along the horizontal direction, a first adjusting block 362 clamped in the first adjusting base 361, and a first adjusting piece 363 driving the first adjusting block 362 to move along the first adjusting base 361; the second adjusting assembly 370 includes a second adjusting seat 371 extending along the vertical direction, a second adjusting block 372 fastened in the second adjusting seat 371, and a second adjusting member 373 driving the second adjusting block 372 to move along the second adjusting seat 371. The first adjusting assembly 360 and the second adjusting assembly 370 cooperate to adjust the axial direction of the first adjusting roller 340 to be parallel to the material reel 2 or the auxiliary material reel 310, so as to ensure that the position of the base material 1 or the auxiliary material 7 entering the roll changing assembly 320 is consistent, and further ensure that the base material 1 or the auxiliary material 7 does not deviate from the preset position due to the inclination of the first adjusting roller 340 during the tape-moving process. The first adjustment roller 340 is driven to rotate when the substrate 1 or the auxiliary material 7 is carried. It should be noted that the "horizontal direction" described herein is specifically the left-right direction in fig. 3, and the "vertical direction" is specifically the up-down direction in fig. 3. The horizontal direction and the vertical direction are perpendicular to each other in the vertical plane, so that the two axial ends of the first adjusting roller 340 can be adjusted to be at the same height by the cooperation of the first adjusting assembly 360 and the second adjusting assembly 370, and the first adjusting roller 340 is axially parallel to the material reel shaft 2.

Further, the first adjusting roller 340 is disposed on the first mounting plate 3, and in order to facilitate the adjustment of the axial directions of the first and second adjusting assemblies 360 and 370, one end of the first adjusting roller 340 is rotatably disposed in the first adjusting block 362 via a joint bearing 380.

In one embodiment, the first adjusting base 361 is provided with a slot extending along a horizontal direction, and the first adjusting block 362 is clamped in the slot and can move along the slot. The first adjustment block 362 is provided with a threaded hole extending along the horizontal direction, and the first adjustment piece 363 is provided with a screw rod section capable of being screwed into the threaded hole and matched with the threaded hole. Thus, the knob first adjuster 363, first adjuster block 362, is movable along the screw section. More specifically, the screw section of the first adjustment piece 363 is parallel to the extending direction of the locking slot and extends along the horizontal direction, and the first adjustment piece 363 is fixedly connected with the first adjustment seat 361. During debugging, the first adjusting piece 363 is turned to drive the first adjusting block 362 to move along the clamping groove, so that the position of one end of the first adjusting roller 340 in the horizontal direction is adjusted, and the connection line of the projections of the two axial ends of the first adjusting roller 340 in the horizontal plane is parallel to the axial direction of the material reel 2. The first adjustment piece 363 is preferably a manual adjustment disc with a screw section, which facilitates manual operation of the first adjustment piece 363. The specific structure of the second adjusting assembly 370 is similar to that of the first adjusting assembly 360, and the difference is that a clamping groove formed in the second adjusting seat 371 extends in the vertical direction, and a threaded hole formed in the second adjusting block 372 extends in the top of the second adjusting block 372 and in the vertical direction, during debugging, the second adjusting member 373 is turned, and the second adjusting block 372 moves in the vertical direction along a screw section of the second adjusting member 373, so as to adjust the position of the other end of the first adjusting roller 340 in the vertical direction, and thus adjust the two axial ends of the first adjusting roller 340 at the same height.

Since both the base material 1 and the auxiliary material 7 need to enter the reel change assembly 320, it is preferable to arrange the stock reel 2 and the auxiliary stock reel 310 in parallel to ensure that the base material 1 and the auxiliary material 7 enter the downstream equipment in the same state. In order to avoid the mutual interference between the feeding positions of the substrate 1 or the auxiliary material 7, in one embodiment, as shown in fig. 3, the first adjusting roller 340 is disposed above the material reel 2 and the auxiliary material reel 310, and the substrate 1 paid out from the material reel 2 directly winds around the first adjusting roller 340 and enters the reel change assembly 320, at this time, the first adjusting roller 340 also serves as a guide roller corresponding to the substrate 1, and the substrate 1 is guided into the reel change assembly 320 while the substrate 1 paid out from the material reel 2 is prevented from interfering with other devices. The auxiliary material 7 paid out from the auxiliary material reel 310 is wound around the guide roller 330 and then enters the first adjustment roller 340. At this time, the guide roller 330 is mainly used for guiding the auxiliary material 7 away from the first adjusting roller 340 to avoid the material reel 2 and the substrate 1 thereon, so as to facilitate the auxiliary material 7 to enter the first adjusting roller 340.

Further, the material reel 2, the auxiliary material reel 310, the guide roller 330, and the first aligning roller 340 are disposed in parallel to receive the base material 1 or the auxiliary material 7.

In this application, either the substrate 1 or the auxiliary material 7 enters the downstream equipment. To ensure that the substrate 1 or the auxiliary material 7 entering the downstream equipment is in a predetermined position for the downstream equipment to handle, the auxiliary material reel 310 is also connected to the deviation rectifying assembly 100. The deviation correcting assembly 100 is connected to and drives the auxiliary material reel 310 in its axial direction, i.e., the axial movement of the material reel 2.

Specifically, two sets of the deviation-correcting guide bearings 120 are arranged corresponding to the material reel 2 and the auxiliary unreeling shaft 310. That is, the deviation rectifying assembly 100 further includes a set of deviation rectifying guide bearings 120 disposed between the first mounting plate 3 and the second mounting plate 4, and the auxiliary material winding shaft 310 passes through the deviation rectifying guide bearings 120 to connect the deviation rectifying driving assembly 110 and the auxiliary unwinding driving member 311. More specifically, the auxiliary unwinding shaft 310 sequentially passes through the first mounting plate 3, the deviation-correcting guide bearing 120 and the second mounting plate 4, the auxiliary unwinding shaft 310 winds the auxiliary material 7 through one end of the first mounting plate 3, one end of the auxiliary unwinding shaft 310, which passes through the second mounting plate 4, is connected to the deviation-correcting driving assembly 110, and the deviation-correcting driving assembly 110 drives the auxiliary unwinding shaft 310 to move along the deviation-correcting guide bearing 120. The material reel 2 assists the material reel 310 to pass through one end of the second mounting plate 4 and is simultaneously disposed on the deviation correcting mounting plate 112. Here, the connection manner of the auxiliary material reel 310 and the offset bearing 120, the deviation rectifying driving assembly 110 and the auxiliary unwinding driving member 311 is the same as the connection manner of the material reel 2 and the offset bearing 120, the deviation rectifying driving assembly 110 and the auxiliary unwinding driving member 311, and the description thereof is omitted.

Since the substrate 1 or the auxiliary material 7 is wound around the guiding roller 330 and the first adjusting roller 340, which have a certain wrap angle on the guiding roller 330 and the first adjusting roller 340, that is, the guiding roller 330 and the first adjusting roller 340 also have an influence on the position of the substrate 1 or the auxiliary material 7, the deviation rectifying assembly 100 is further connected to the guiding roller 330 and the first adjusting roller 340 to drive the guiding roller 330 and the first adjusting roller 340 to move along the axial direction thereof, that is, the axial direction of the material reel 2, so as to rectify the position of the substrate 1 or the auxiliary material 7 with the batch reel 2 or the auxiliary material reel 310.

In a specific embodiment, the guiding roller 330 and the first adjusting roller 340 are connected to the deviation-rectifying mounting plate 112 by passing through the first mounting plate 3 and the second mounting plate 4 at one end close to the first mounting plate 3, so that when the deviation-rectifying driving member 111 drives the deviation-rectifying mounting plate 112 to move, the material reel 2, the auxiliary material reel 310, the guiding roller 330 and the first adjusting roller 340 can be driven to synchronously move along the axial direction of the material reel 2, thereby realizing the position deviation rectifying of the substrate 1 or the auxiliary material 7.

Further, the deviation rectifying assembly 100 further comprises a deviation rectifying detection member 130 for detecting the position state of the substrate 1 or the auxiliary material 7. The deviation-correcting detection part 130 is preferably a CCD camera, and is used for taking a picture of the substrate 1 or the auxiliary material 7 paid out by the material reel 2 and the auxiliary material reel 310 to obtain the current position of the substrate 1 or the auxiliary material 7, transmitting the information to the control system, judging and calculating the position deviation of the substrate 1 or the auxiliary material 7 by the control system, and feeding the position deviation back to the deviation-correcting driving part 111, and adjusting the substrate 1 or the auxiliary material 7 to a preset station by driving the material reel 2 or the auxiliary material reel 310 to move along the axial direction thereof by the deviation-correcting driving part 111. Referring to fig. 3, the deviation detecting member 130 is disposed above the first adjusting roller 340, and is used for detecting the position of the substrate 1 or the auxiliary material 7 passing around the first adjusting roller 340.
