Background

In the prior art, when the working material belt on the working material roll is about to run out, the standby material belt on the standby material roll needs to be stuck with the working material belt in time, so that the winding needle on the turret can continuously wind the material belt to produce the battery cell. In the prior art, the starting end of the spare material belt is provided with a double-sided adhesive tape, the tail end of the working material belt is automatically connected with the starting end of the spare material belt, and the specific implementation mode is as follows: the tail end of the working material belt is driven to swing to the starting end of the spare material belt on the spare material roll by the swing arm, and the starting end of the spare material belt is firstly stuck with double faced adhesive tape, so that the tail end of the working material belt is connected with the starting end of the spare material belt. This approach has the following disadvantages: the double faced adhesive tape between the tail end of the working material tape and the starting end of the spare material tape is not adhered with the material tape on one side, so that the adhesive can be adhered to the passing roller in the conveying process of the material tape on the side, and the risk that the material tape is adhered by the adhesive on the passing roller exists.

Therefore, the tail end of the working material belt and the head end of the standby material belt cannot be adhered together by adopting double-sided adhesive tape, and a single-sided adhesive tape mode is adopted. However, in the prior art, a semi-automatic mode is basically adopted in a mode of bonding the tail end of the working material belt and the starting end of the standby material belt together by single-sided adhesive tape, the starting end needs to be torn manually, the labor intensity of workers is increased, and the belt receiving efficiency of the material belt is affected.

In the following description, each driving member can use a power source such as a cylinder or a motor, and a driving manner such as a piston driving manner and a rack-and-pinion driving manner is adopted.

In the following description, the material strip, roll, start end and end are used only to describe the working principles of the automatic reel changer and the cell winding device and should not be considered as part of any mechanism, device and device.

As shown in fig. 1 and 2, the beginning 207 of the roll 205 is attached using a sealer 206.

For clarity of description, the roll 205 that is unwinding the tape for cell winding is labeled herein as the working roll 201, the roll 205 that has not been unwinding the tape for cell winding is labeled as the standby roll 202, the tape that is being cell wound is labeled as the working tape 203, and the tape that has not been cell wound is labeled as the standby tape 204. In the following description, the first reel-out shaft 101 is used to load the work roll 201, and the second reel-out shaft 102 is used to load the standby roll 202, and in practical application, the first reel-out shaft 101 can also load the standby roll 202, and the second reel-out shaft 102 can also load the work roll 201.

In the embodiment shown in fig. 3-8, the backup roll 202 rotates clockwise, while in the embodiment shown in fig. 9-14, the backup roll 202 rotates counterclockwise.

As shown in fig. 3 to 28, the automatic reel changer 100 in the present embodiment includes: the head lifting mechanism 300, wherein the head lifting mechanism 300 comprises a first material taking piece 303, and the first material taking piece 303 can move between a head lifting station and a transferring station to pick up the head lifting end 207 of the standby material belt 204 on the standby material roll 202 and drive the head lifting end 207 of the standby material belt 204 to be separated from the standby material roll 202 and move in a direction away from the standby material roll 202; a transfer mechanism 400, wherein the transfer mechanism 400 comprises a second material taking member 401, and the second material taking member 401 can move between a transfer station and a tape receiving station so as to transfer the beginning end of the standby tape 204 on the first material taking member 303 to the tape receiving station; the rubberizing mechanism 500, rubberizing mechanism 500 includes and connects the area subassembly 501, connect the area subassembly to be located and connect the area station, connect the area subassembly 501 can adsorb the first end 207 of the spare material area 204 on the second material piece 401, make single face glue bond the tail end of working material area 203 and the first end of spare material area 204 together.

More specifically, as shown in fig. 3, the first take-out member 303 is now located at a take-up station where the first take-out member 303 picks up the take-up end 207 of the backup tape 204 on the backup roll 202. As shown in fig. 4, the first material taking member 303 keeps picking up the leading end 207 of the standby tape 204, moves to the transfer station, and during the movement, the first material taking member 303 drives the leading end 207 of the standby tape 204 to separate from the standby roll 202 and move in a direction away from the standby roll 202, so that the sealing compound 206 is torn off, the second unwinding shaft 202 rotates clockwise, and the standby tape 204 is pulled out. Rotation of the second unwind spool 202 may prevent the backup ribbon 202 from being torn. At the transfer station, the second take off member 401 picks up the beginning 207 of the backup strip 204 from the first take off member 303. As shown in fig. 5, at the splicing station, two splicing assemblies 501 are brought close to each other to sever the work material tape 203, and the tail end of the work material tape 203 is sucked by one splicing assembly 501. The two splice assemblies 501 are then moved away from each other. As shown in fig. 6, the second take-off 401 moves to the splicing station so that the beginning 207 of the standby tape 204 also reaches the splicing station. The two ribbon assemblies 501 are then brought into proximity with each other. As shown in fig. 7, the leading end 207 of the backup tape 204 is attracted to another tape splicing assembly 501. The two splicing assemblies 501 are then moved away from each other and the second material take-off 401 exits the splicing station. The two ribbon assemblies 501 are then brought into proximity with each other. As shown in fig. 8, the leading end 207 of the backup tape 204 and the trailing end of the working tape 203 are adsorbed by the same splicing assembly 501. The two tape splicing assemblies 501 are then moved away from each other and the other tape splicing assembly is ready for single facer. The two tape splicing assemblies 501 are then brought into proximity with one another and the other tape splicing assembly 501 causes the single facer to adhere the tail end of the work tape 203 and the leading end 207 of the backup tape 204 together. Next, the working tape 203 and the standby tape 204 are adsorbed (not shown) by the tape splicing assembly 501 on the left side in the drawing, and the tape splicing assembly 501 on the right side adheres the single-sided adhesive tape to the tail end of the working tape 203 and the other side of the standby tape 204. Finally, both splicing assemblies 501 no longer absorb the work material tape 203 and the spare material tape 204, and the second unreeling shaft 102 continues unreeling the material tape, and the reel change is completed.

From the above description, the whole process of starting and transferring to the tape splicing is free from manual participation, and the single-sided adhesive tape can be used for realizing the adhesion of the working material tape and the standby material tape, so that the working efficiency is high and the tape splicing accuracy is high.

As shown in fig. 3, 4, 8, 15 and 16, the head raising mechanism in the present embodiment includes: a mounting base 301; a moving seat 302, wherein the moving seat 302 is in sliding fit with the mounting seat 301, the moving seat 302 is provided with a first material taking member 303, and the first material taking member 303 is used for picking up the starting end 207 of the standby material belt 204 on the standby material roll 202; a first driving member 305, where the first driving member 305 can drive the moving base 302 to move, so that the first material taking member 303 moves (moves in the third direction shown in fig. 3) between the starting station and the transferring station.

More specifically, the movable seat 302 can be slidably engaged with the mount 301 by a slide rail, a guide rod, or the like. The first picking member 303 may be configured to create a negative pressure by connection to a vacuum mechanism to draw the pick-up head 207 or by a jaw mechanism to grip the pick-up head 207 to pick up the pick-up head 207. In operation, the first pick-up member 303 picks up the leading end 207 of the standby tape 204 on the standby roll 202 by adsorption, grabbing, or the like, and then the first driving member 305 drives the moving seat 302 to move. Since the first material taking member 303 is kept in the state of picking up the leading end 207, the moving seat 302 will make the first material taking member 303 drive the leading end 207 of the standby tape 204 to separate from the standby roll 202 during the moving process, and the sealing compound 206 is torn. The first takeout member 303 continues to move away from the reserve roll 202 and the second unwind shaft 102 rotates to unwind the reserve tape 204, the reserve tape 204 being pulled from the reserve roll 202 for subsequent splicing with the working tape 203. Rotation of the second unwind spool 102 can prevent the backup ribbon 204 from tearing during the pulling process.

As can be seen from the above description, the unwinding process of the standby roll 202 does not need to be manually performed, the first material taking member 303 can automatically tear the sealing compound 205, and the unwinding efficiency is improved.

As shown in fig. 8, the first take-off member 303 has a first take-off end 306 and a second take-off end 307 that are opposite. More specifically, when the backup roll 202 is loaded on the first unreeling shaft 101, the first take-out end 306 is used to pick up the beginning end 207 of the backup tape 204 on the backup roll 202 loaded on the first unreeling shaft 101; the second take-off end 307 is used to pick up the beginning end 207 of the backup tape 204 on the backup roll 202 loaded on the second unwind shaft 102 when the backup roll 202 is loaded on the second unwind shaft 102. Thus, the head ends 207 of the standby tapes 204 on the standby rolls 202 on both sides can be picked up by the movement of the movement seat 302, and the versatility is high. The first and second take-off ends 306, 307 are capable of picking up the head end 207 by vacuum suction, grasping, or the like.

As shown in fig. 3 and 15, the head lifting mechanism 300 further includes a first sensor 304, where the first sensor 304 is configured to detect a position of the head end 207 of the standby tape 204 on the standby roll 202, and the first driving member 305 drives the moving seat 302 to move according to the head end position signal detected by the first sensor 304, so that the first material taking member 303 reaches the position of the head end 207 of the standby tape 204 on the standby roll 202.

More specifically, during the rotation of the second unwinding shaft 102, the first sensor 304 may detect the position of the start end 207 of the backup tape 204 on the backup roll 202 by identifying the color, the image, etc. of the seal adhesive 206, determine whether the start end 207 reaches the position range that can be picked up by the first pick-up member 303, and if the start end 207 is detected to reach the position range that can be picked up by the first pick-up member 303, the first sensor 304 may send a start end position signal, and the first driving member 305 may drive the moving seat 302 to move toward the direction approaching the backup roll 202 according to the start end position signal detected by the first sensor 304, so that the first pick-up member 303 reaches the position of the start end 207 of the backup tape 204 on the backup roll 202, and the first pick-up member 303 picks up the start end 207. The first driving member 305 may be fixed to the mounting base 301, or may be fixed in other suitable positions. For example, in the present embodiment, the first driving member 305 is a motor screw driving assembly, the motor is fixedly mounted on the mounting seat 301, the output shaft of the motor drives the screw to rotate, and the screw is in threaded engagement with the nut on the movable seat 302 or is directly engaged with the threaded hole on the movable seat 302, so as to drive the movable seat 302 to move.

More specifically, the first sensor 304 may be used with a color sensor or an image sensor or a variety of sensors.

The color sensor may employ, for example, an integrated light-to-voltage converter or an integrated light-to-frequency converter to identify the color of the sealer 206 and thus the position of the beginning 207 of the backup tape 204 on the backup roll 202. The image sensor may employ, for example, a CCD camera or a CMOS camera to identify the shape of the leading end 207 of the backup tape 204 on the backup roll 202 and thus the position of the leading end 207.

As shown in fig. 15, the first sensor 304 is mounted on the movable base 302, and the movable base 302 is mounted with a second driving member 308, and the second driving member 308 drives the first sensor 304 to rotate toward the first material taking end 306 or toward the second material taking end 307.

More specifically, when it is desired to pick up the leading end of the backup tape 204 on the backup roll 202 loaded on the first reel spool 101 with the first take-out end 306, the second driving member 308 drives the first sensor 304 to rotate toward the first take-out end 306 side to detect the leading end position of the backup tape 204 on the backup roll 202; when the second take-out end 307 is required to pick up the leading end of the backup tape 204 on the backup roll 202 loaded on the second unreeling shaft 102, the second driving member 308 drives the first sensor 304 to rotate toward the second take-out end 307 side to detect the leading end position of the backup tape 204 on the backup roll 202. Thus, a first sensor 304 can be used to detect the position of the beginning end of the backup tape 204 on the backup roll 202 on both sides of the beginning mechanism, which is less costly and the first sensor 304 moves with the movable base 302 with greater sensitivity to position.

In practice, the first sensor 304 can also be mounted at other locations suitable for detecting the beginning 207 of the backup tape 204 on the backup roll 202.

As shown in fig. 16, this embodiment specifically describes a first material taking member 303 of the adsorption type. The first material taking end 306 of the first material taking member 303 has a first adsorbing block 309 and a second adsorbing block 310 spaced apart from each other in the first direction, wherein the adsorbing holes on the first adsorbing block 309 are in communication with a first vacuumizing device 311 (indicated by one vacuumizing hole in fig. 16), and the adsorbing holes on the second adsorbing block 310 are in communication with a second vacuumizing device 312 (indicated by one vacuumizing hole in fig. 16). The first vacuumizing device 311 and the second vacuumizing device 312 can work independently. This configuration can improve the reliability of the leading end 207 of the pick-up ribbon of the first picking member 303, and if one of the evacuators is inadequate or fails, the other evacuator can also maintain the suction of the spare ribbon 204.

Similarly, the second material taking end 307 can also have a first adsorption block 309 and a second adsorption block 310 that are spaced apart from each other in the first direction, wherein the adsorption holes on the first adsorption block 309 are in communication with the first vacuum device 311, and the adsorption holes on the second adsorption block 310 are in communication with the second vacuum device 312. The first vacuumizing device 311 and the second vacuumizing device 312 can work independently. Or the first material taking end 306 and the second material taking end 307 can also adopt other structures respectively.

In actual operation, the first direction refers to the length direction of the spare belt 204 that is absorbed by the first material taking end 306 or the second material taking end 307. The advantage of the first suction block 309 and the second suction block 310 being spaced apart from each other in the first direction is that, first, the first material taking part 303 is simply processed, and compared with the space in the direction of the material belt width, the first suction block 309 and the second suction block 310 can meet the suction requirement on the material belt only by processing a smaller number of suction holes, and the first vacuum-pumping device 311 and the second vacuum-pumping device 312 can also be connected on the same side of the first material taking part 303, so that the processing is simple and the layout is compact.

As shown in fig. 15, the mounting base 301 is mounted with a first wire rail 313, the moving base 302 is mounted with a slider 314, and the slider 314 is slidingly engaged with the first wire rail 313. This linear motion is a larger range of compatible roll diameters relative to the swing arm motion, as the movable mount 302 only requires translational motion beneath the backup roll 202 and the work roll 201.

As shown in fig. 3, 4 and 15, in the present embodiment, the first unwinding shaft 101 is rotating to unwind the work ribbon 203, and the work ribbon 203 is being conveyed toward a winding needle (not shown) to perform cell winding. The second unwinding shaft 102 is loaded with the standby roll 202, and after the second unwinding shaft 102 rotates clockwise until the seal compound 206 of the standby roll 202 enters the detection range of the first sensor 304, the first sensor 304 can detect the beginning end position of the standby tape 204 on the standby roll 202 by identifying the seal compound 206. Or by controlling the angle of rotation of the second unwind spool 102 to ensure that the beginning end 207 of the backup tape 204 on the backup roll 202 reaches the beginning station. The first drive member 305 then drives the movable carriage 302 in a direction toward the backup roll 202 (and correspondingly away from the work roll 201), and the second take-off end 307 of the first take-off member 303 picks up the take-off end 207 at the take-off station. Then, the first driving member 305 drives the moving seat 302 to move in a direction away from the standby roll 202 (correspondingly, close to the working roll 201), the sealing compound 206 is torn, the second unreeling shaft 102 rotates to unreel the standby roll 204 along with the starting end 207 away from the standby roll 202, and the first material taking member 303 pulls the standby roll 204 out, so that the working roll 203 and the standby roll 204 are conveniently connected in sequence, and roll replacement is completed. The whole roll changing process does not need to manually tear the sealing glue 206, so that the roll changing efficiency is higher.

When the work roll on the second unreeling shaft 102 is about to be unreeled, the first unreeling shaft 101 rotates until the seal gum 206 of the standby roll 202 enters the detection range of the first sensor 304, and the first sensor 304 can detect the beginning end position of the standby roll tape 204 on the standby roll 202 by identifying the seal gum 206. The first driver 305 then drives the movable carriage 302 in a direction toward the backup roll 202 (and correspondingly away from the work roll 201), and the first take-off end 306 of the first take-off 303 picks up the pick-up end 207. Then, the first driving member 305 drives the moving seat 302 to move in a direction away from the standby roll 202 (correspondingly approaching to the working roll 201), the sealing compound 206 is torn, the first unreeling roll 101 rotates to unreel the standby material belt 204, and the first material taking member 303 pulls the standby material belt 204 out, so that the working material belt 203 and the standby material belt 204 are conveniently spliced at the tape splicing assembly, and the roll replacement is completed.

In other words, the moving seat 302 drives the first material taking member 303 to reciprocate between the first unwinding shaft 101 and the second unwinding shaft 102, and the first material taking member is close to the first unwinding shaft 101 and the second unwinding shaft 102, so that the sealing compound 206 on the standby material tape 202 on the first unwinding shaft 101 and the second unwinding shaft 102 can be torn off, the automation degree is high, and the occupied space is small.

The first driving member 305 drives the moving seat 302 to move between the first unwinding shaft 101 and the second unwinding shaft 102, which may be a translational movement or a curved movement, as long as the first material taking member 303 can reach the position of the beginning end 207 of the standby material belt 204 on the standby material roll 202. In this embodiment, the first driving member 305 drives the moving seat 302 to move in translation between the first unwinding shaft 101 and the second unwinding shaft 102, which can save space and avoid the material rolls on the first unwinding shaft 101 and the second unwinding shaft 102 as much as possible, so as to adapt to a larger size range of the material rolls.

More specifically, the translational movement may be implemented by adopting a manner that the first wire rail 312 is matched with the slider 313, or may be implemented by forming a chute on the mounting seat 301, or may be implemented by converting the rotation of the motor into the translational movement by using a screw structure.

In this embodiment, when the first sensor 304 detects the position of the beginning end of the standby tape 204 on the standby roll 202, the first unwinding shaft 101 or the second unwinding shaft 102 loaded with the standby roll 202 stops rotating or rotates by a predetermined angle according to the signal of the beginning end position, until the position of the sealing compound 205 can be aligned with the first material taking member 303, which is beneficial to more accurate position of the first material taking member 303 for picking up the beginning end 207 and improves the accuracy of subsequent tape splicing. Whether the first reel 101 and the second reel 102 stop rotating or not, and the predetermined angle required for the rotation can be calibrated in advance by a test method, and the first reel 101 and the second reel 102 may rotate or stop rotating according to the calibration.

As shown in fig. 3, the automatic reel changer further includes a second sensor 103, the second sensor 103 is configured to detect a diameter of the standby reel 202, and the first driving member 305 drives the moving seat 302 to move to a predetermined position according to a diameter signal detected by the second sensor 103, so that the start end 207 of the standby reel 204 on the standby reel 202 can enter a detection range of the first sensor 304.

More specifically, the second sensor 103 can indirectly obtain the diameter of the backup roll 202 from the position signal of the edge of the backup roll 202, or can obtain the diameter of the backup roll 202 using ultrasonic detection. Then, the first driving member 305 drives the moving seat 302 to move to a predetermined position according to the diameter signal detected by the second sensor 403, the predetermined position may be a position calibrated in advance according to different diameters, and after the first sensor 304 itself has a limited detection range, the start end of the standby tape 204 on the standby roll 202 can be ensured to enter the detection range of the first sensor 304 after entering the predetermined position, so that the sealing compound 206 can be ensured to be detected, and the problem that the first sensor 304 is too far from the standby roll 202 to detect the start end position cannot occur.

As shown in fig. 3 and 17 to 23, the tape transfer mechanism 400 in the present embodiment further includes: a fixing plate 402; a first support 404, wherein the first support 404 is mounted on the fixed plate 402 and can move along a first direction, and the second material taking member 401 is mounted on the first support 404 and can move along a second direction; the third driving piece 405 is configured to drive the first support 404 to move so as to drive the second material taking piece 401 to move between a transferring station and a tape receiving station; the first direction intersects the second direction.

More specifically, as shown in fig. 3 and 17, the up-down direction of the paper surface is marked as a first direction, the second direction is a direction perpendicular to the paper surface, or an included angle between the first direction and the second direction can be other angles, and the two directions are not parallel. The first support 404 is slidably engaged with the fixed plate 402 by a third wire rail 410 mounted on the fixed plate 402, the third wire rail 410 extending in a first direction, or by other transmission mechanisms such as racks, to enable movement of the first support 404 in the first direction. The second take-off member 401 is capable of picking up the leading end 207 of the take-off strip by suction, clamping, or the like. The second take-off member 401 is mounted to the first support 404 and is movable in a second direction, i.e., if referenced to the second surface 417 of the fixed plate 402, the second take-off member 401 may have a length in the second direction that is further from the second surface 417 or a length in the second direction that is further from the second surface 417. Thus, when a transfer tape is desired, the second take off 401 is moved in the second direction to have a length further away from the second surface 417 to pick up and transfer the tape; when the material belt is not required to be transported, the second material taking member 401 moves along the second direction to have a length closer to the second surface 417, avoiding other mechanisms, and saving space. The third driving member 405 may be a motor, an air cylinder, or the like, for driving the first support 404 to move along the first direction, so that the first support 404 moves to drive the second material taking member 401 to move in the first direction, so as to reach the transferring station or the tape receiving station. The third driver 405 can be mounted to the fixed plate 402 or other suitable location.

Therefore, the second material taking member 401 can transfer the starting end 207 of the material belt from the transferring station to the belt receiving station without manually threading, so that the automation degree is improved, and the production efficiency is improved. The second material taking member 401 can extend out of the through groove 403 or retract in the second direction, so that the work of other mechanisms can be avoided, and the occupied space is small.

In this embodiment, the fixing plate 402 is provided with a through slot 403 extending along the first direction, and the second material taking member 401 may extend out of the through slot 403 along the second direction.

More specifically, the through groove 403 extends in the first direction, which means that the first direction is the length direction of the through groove 403. Since the through slot 403 also extends along the first direction, the first support 404 can move along the first direction to drive the second material taking member 401 to move in the first direction. The second material taking member 401 may extend out of the through slot 403 along the second direction, which means that the second material taking member 401 may also retract along the second direction, and may partially retract or may fully retract. Thus, when the material belt is required to be transported, the second material taking part 401 extends out of the through groove 403 along the second direction, and when the material belt is not required to be transported, the second material taking part 401 retreats to avoid the work of other mechanisms, so that the space is saved. The through slot 403 is designed to protect the driving mechanisms of the second material taking member 401 and prevent the driving mechanisms of the material belt transferring mechanism 400 from interfering with the flatness of the material belt itself during operation.

As shown in fig. 17, the tape transferring mechanism 400 further includes a fourth driving member 406, where the fourth driving member 406 is configured to drive the second material taking member 401 to rotate about the axis L of the second material taking member 401.

More specifically, the fourth driving member 406 may be a motor capable of directly outputting a rotational motion, and may be a mechanism for converting a linear motion of a cylinder into a rotational motion using a rack and pinion mechanism for driving the second material taking member 401 to rotate about the axis L thereof. The fourth driver 406 can be mounted to the first support 404 or other suitable location. In this way, the second take-off member 401 is adapted for clockwise and counterclockwise rotation of the standby spool 202, while also being adapted for the first and second unwind spool 101, 102 arrangements described below.

As shown in fig. 17 and 18, the tape transfer mechanism 400 in the present embodiment further includes: a second support 407, the second support 407 being mounted to the first support 404 and being movable in a second direction, the second take-off member 401 being mounted to the second support 407; a fifth drive member 408, wherein the fifth drive member 408 is configured to drive the second support 407 to move to adjust the position of the second material taking member 401 in the second direction.

More specifically, in the present embodiment, the second support 407 is slidably engaged with the first support 404 by a second wire rail 409, and the second wire rail 409 is mounted on the first support 404 and extends in the second direction. The second support 407 is also movable in a second direction by means of, for example, a belt drive, a rack drive, or the like. The second material taking member 401 is mounted on the second support 407, and since the second support 407 is mounted on the first support 404, the second material taking member 401 can be regarded as being indirectly mounted on the first support 404. The fifth driving member 408 may be a driving mechanism such as a motor or a cylinder, and drives the second support 407 to move in the second direction, so that the position of the second material taking member 401 in the second direction can be adjusted after passing through the through slot 403. The fifth driver 408 may be mounted to the first support 404 or other suitable location. In this embodiment, the third driving member 405 is mounted to the fixed plate 402, the fourth driving member 406 is mounted to the second support 407, and the fifth driving member 408 is mounted to the first support 404.

An advantage of this configuration is that the second take-off member 401 has the freedom to translate in the second direction, enabling alignment of the standby band 204 with the edge of the working band 203.

In the embodiment shown in fig. 17, the fifth drive member 408 is actuated by an air cylinder, while in another embodiment shown in fig. 21, the fifth drive member 408 includes a servo motor fixedly mounted to the first support 404, the servo motor driving the second support 407 to move to adjust the position of the reserve belt 204 on the second take-out member 401 in the second direction.

The servo motor has higher accuracy, and can accurately control the position of the second material taking member 401 in the second direction, so that the adjustment of the position of the spare material belt 204 in the second direction is more accurate.

As shown in fig. 17, the first support 404 is slidably connected to the fixing plate 402, and the third driving member 405 includes a motor fixedly mounted on the fixing plate 402, and the motor drives the first support 404 to move through a screw 414.

More specifically, the first support 404 is slidably connected to the fixed plate 402 via a third rail 410, and may also be slidably connected by way of a chute. The third driving member 405 includes a motor, the housing of which is fixedly mounted on the fixed plate 402, and the motor drives the screw 414 to rotate, and the screw 414 drives the first support 404 to move in the first direction through a screw member connected to the first support 404 or through a screw engagement of an internal threaded hole directly machined in the first support 404. This configuration enables the second take-off member 401 to be moved in the first direction with greater precision.

As shown in fig. 17 and 21, the second material taking member 401 includes a third adsorption block 412, and the third adsorption block 412 is provided with adsorption holes, and the adsorption holes are communicated with a vacuum pumping device (not shown).

More specifically, shown in this embodiment is an adsorptive second take off 401. The second material taking member 401 includes a third adsorption block 412, and adsorption holes on the third adsorption block 412 are communicated with a vacuumizing device through a vacuumizing tube 413. When the vacuumizing device works, negative pressure is generated at the adsorption holes on the third adsorption block 412, so that the material belt can be adsorbed on the third adsorption block 412. The structure can ensure that the material belt is not damaged in the transferring process as much as possible. The second take off 401 can also take off the leading end 207 of the web using a clamping jaw or the like.

As shown in fig. 11, 19 and 20, the second material taking member 401 has a third material taking end 414 and a fourth material taking end 415, and the third material taking end 414 is disposed opposite to the fourth material taking end 415.

More specifically, the third dispensing end 414 and the fourth dispensing end 415 can both pick up the strip by suction or by clamping. The third and fourth take-off ends 414, 415 are disposed opposite one another, one in the direction of the first unwind spool 101 and the other in the direction of the second unwind spool 102, suitable for switching between loading the work rolls 201 and the reserve rolls 202.

As shown in fig. 18 and 19, the fixing plate 402 has a first surface 416 and a second surface 417 opposite to each other, and the through slot 403 extends through the first surface 416 and the second surface 417.

As shown in fig. 22 and 23, the fixing plate 402 is fixedly provided with a third support 419, the third support 419 is provided with a support rod 420 and a sixth driving member 421, a positioning hole 418 is provided at the top end of the second material taking member 401, and the sixth driving member 421 can drive the support rod 420 to cooperate with the positioning hole 418.

More specifically, since the second take-off member 401 needs to have a certain length in the second direction, a cantilever is formed. At the transfer station shown in fig. 4, the second material taking member 401 and the first material taking member 303 need to be pressed against each other to transfer the spare material tape 204 from the first material taking member 303 to the second material taking member 401, thereby causing the second material taking member 401 to be easily deformed by the pressing force. Thus, the present embodiment provides the third support 419 and the support pole 420. After the supporting rods 420 are matched with the positioning holes 418 at the top end of the second material taking part 401, the supporting rods 420 provide supporting force for the second material taking part 401, so that the pressure resistance of the second material taking part 401 can be improved, the second material taking part 401 is protected, and the second material taking part 401 is prevented from deforming to influence the follow-up tape splicing accuracy. After the second material taking member 401 picks up the spare material tape 204 from the first material taking member 303, the sixth driving member 421 drives the supporting rod 420 to disengage from the positioning hole 418, and the second material taking member 401 moves in the first direction for tape transfer.

As shown in fig. 3, the automatic reel changer 100 further includes a third sensor 109, where the third sensor 109 is configured to detect edges of the working tape 203 and the standby tape 204, and the fifth driving member 408 of the tape transferring mechanism drives the second support 407 to move according to the edge signal detected by the third sensor 109 to adjust the position of the second material taking member 401 in the second direction, so that the edge of the working tape 203 is aligned with the edge of the standby tape 204.

More specifically, as shown in fig. 3 and 8, when the work material tape 203 is adhered to the backup material tape 204, since the second material taking member 401 initially picks up the leading end 207 of the material tape from the first material taking member 303, the pick-up position does not necessarily ensure that the edge of the backup material tape 204 is aligned with the work material tape 203, which if not aligned, causes misalignment of the tape splicing backup material tape 204 and the work material tape 203 in the width direction (i.e., the second direction). Accordingly, it is desirable that the third sensor 109 detect the edges of the work and reserve belts 203, 204 and then transmit an edge signal to the fifth driver 408, and the fifth driver 408 drives the second support 407 to move in the second direction according to the distance between the edge of the work and reserve belts 203, 204, and adjusts the position of the second material taking member 401 in the second direction, and the second material taking member 401 correspondingly drives the reserve belt 204 to move in the second direction to adjust the position of the reserve belt 204 in the second direction until the work and reserve belts 203 are aligned with the edge of the reserve belt 204.

As shown in fig. 3 and 24, the rubberizing mechanism 500 in the present embodiment further includes a rubberizing assembly 502. The tape receiving assembly 501 comprises a rubberizing element 525, wherein the rubberizing element 525 comprises a first adsorption element 527 and a second adsorption element 526, the first adsorption element 527 is used for adsorbing single-sided adhesive tape, and the second adsorption element 526 is used for adsorbing material tape; the glue preparation assembly 502 is configured to place a length of single-sided glue onto the first absorbent component 527.

More specifically, the first absorbent component 527 adsorbs single-sided tape, and the second absorbent component 526 adsorbs a tape (e.g., a pole piece, a diaphragm). The glue preparation assembly 502 may place a section of single-sided glue onto the first suction attachment 527, and the glue preparation may be performed in the manner shown in fig. 24 to 26, or may be performed in any other suitable manner, for example, by pulling a section of single-sided glue with a pair of clamping jaws, placing it onto the first suction attachment 527, and cutting it off. Because the glue preparation component 502 can place a section of single-sided glue in the first absorption part 527, manual glue preparation is not needed in the tape splicing process, and the glue pasting part 525 has the functions of absorbing single-sided glue and absorbing material tapes, so that the automation degree and the tape splicing efficiency are improved, and the space needed in the tape splicing process is smaller.

As shown in fig. 24 to 26, the present embodiment provides a specific structure of the rubberizing mechanism 500.

The glue preparation assembly 502 includes: a mounting plate 503, wherein the mounting plate 503 is provided with a rotatable single-sided adhesive tape discharging part 504, a single-sided adhesive tape end holding part 505 and a seventh driving part 506. The single-sided adhesive tape discharging member 504 is used for loading a single-sided adhesive tape roll, the single-sided adhesive tape end holding member 505 is used for holding the end of the single-sided adhesive tape, and the seventh driving member 506 is used for driving the first moving plate 507 to move in the second direction to approach or separate from the single-sided adhesive tape end holding member 505. The first moving plate 507 is provided with an eighth driving member 509, the eighth driving member 509 is connected with the second moving plate 510, the second moving plate 510 is provided with a rotatable glue pulling roller 511, the glue pulling roller 511 is used for winding single-sided glue, and the eighth driving member 509 is used for driving the glue pulling roller 511 to move along a first direction to abut against or be away from the single-sided glue end part holder 505; the first direction intersects the second direction.

More specifically, once the single-sided adhesive discharge member 504 is mounted on the mounting plate 503, it is free to rotate or is driven to rotate by a driving mechanism, thereby unwinding the single-sided adhesive roll and feeding the single-sided adhesive toward the single-sided adhesive end holding member 505. The single-sided tape end holder 505 may hold the single-sided tape end of the single-sided tape by adsorption or the like. For example, when an adsorption type structure is employed, the single-sided tape end holder 506 can adsorb the single-sided tape end of the single-sided tape. The seventh driving member 506 is configured to drive the first moving plate 507 to move in the second direction to approach or separate from the single-sided tape end portion holding member 505, and the eighth driving member 509 is mounted on the first moving plate 507 and is capable of driving the second moving plate 510 to move in the first direction, for example, the eighth driving member 509 employs an air cylinder, a piston rod of the air cylinder is connected to the first moving plate 507, a cylinder body is connected to the second moving plate 510, or a piston rod of the air cylinder is connected to the second moving plate 510, and a cylinder body is connected to the first moving plate 507, so that the second moving plate 510 can move in the first direction by telescoping the piston rod. The glue pulling roller 511 is mounted on the second moving plate 510, and can freely rotate or be driven to rotate by a driving member. The first direction intersects the second direction. In this way, the seventh driver 506 can drive the pull roll 511 to move in the second direction toward or away from the single-sided adhesive end holder 505, and the eighth driver 509 can drive the pull roll 511 to move in the first direction to abut or move away from the single-sided adhesive end holder 505.

When the preparation of the adhesive is required, the seventh driving member 506 drives the first moving plate 507 to move along the second direction so that the adhesive pulling roller 511 approaches the single-sided adhesive end part holder 505, wherein "approaching" means that the distance between the first moving plate 507 and the single-sided adhesive end part holder 505 in the second direction becomes smaller. After the glue pulling roller 511 reaches above the single-sided tape end holder 505, the ninth driving member 509 drives the second moving plate 510 to move along the first direction so that the glue pulling roller 511 abuts against the single-sided tape end on the single-sided tape end holder 505 (which can be regarded as that the glue pulling roller 511 abuts against the single-sided tape end holder 505 at this time), and therefore the glue pulling roller 511 abuts against the single-sided tape end. Then, the seventh driving member 506 continues to drive the first moving plate 507 to move along the second direction (the original moving direction is still kept moving at this time), the glue pulling roller 511 rotates, and the single-sided glue is adhered to the roller surface of the glue pulling roller 511, so that the glue pulling roller 511 winds a section of single-sided glue. Then, the single-sided tape end portion holder 505 no longer holds the single-sided tape end portion, and the eighth driving member 509 drives the second moving plate 510 away from the single-sided tape end portion holder 505 in the first direction, so that the pulling roller 511 is also away from the single-sided tape end portion holder 505. Then, the seventh driving member 506 drives the first moving plate 507 away from the single-sided tape end holding member 505 in the second direction, the single-sided tape discharging member 504 rotates, and the single-sided tape is pulled out by a certain length. After the first moving plate 507 reaches the predetermined position, the eighth driving member 509 drives the second moving plate 510 in the first direction to approach the single-sided tape end holder 505, where "approaching" means that the distance between the pull roller 511 and the single-sided tape end holder 505 in the first direction becomes smaller. The single-sided adhesive end holder 505 and the first suction member 527 operate to hold a length of single-sided adhesive, and the adhesive roller 511 spreads the wound length of single-sided adhesive. After the first cutter 513 cuts the single-sided adhesive tape, a length of single-sided adhesive tape is placed on the first suction member 527. The tape splicing component 501 can utilize the second adsorption piece 526 to adsorb the material tape, and utilizes the first adsorption piece 527 to rubberize, so that automatic tape splicing preparation is realized, manual operation is not needed, the tape splicing efficiency is improved, and the structure is compact.

Finally, the eighth drive member 509 drives the second moving plate 510 away from the single-sided tape end holder 505 in the first direction into the next standby cycle.

As shown in fig. 24, the mounting plate 503 is further mounted with a ninth driving member 512, and the ninth driving member 512 is used for driving the first cutter 513 to move so as to cut single-sided tape. A first cutter 513 is located between the single sided tape end holder 505 and the tape applicator 525.

More specifically, a gap can exist between the single-sided tape end holder 505 and the tape applying member 525, and the ninth driving member 512 drives the first cutter 513 to cut the single-sided tape between the single-sided tape end holder 505 and the tape applying member 525, so that a section of single-sided tape can be placed on the first suction member 527 and a new single-sided tape end of the cut single-sided tape is held by the single-sided tape end holder 505. The whole structure layout is compact, and the space utilization rate is high. The ninth drive member 512 and the first cutter 513 can also be mounted in other suitable locations.

As shown in fig. 24 to 26, the second moving plate 510 is further provided with a tenth driving member 514, and the tenth driving member 514 is used to drive the pressing block 515 to clamp the glue pulling roll 511 or to unclamp the glue pulling roll 511.

More specifically, in the process of preparing the single-sided adhesive, after the single-sided adhesive is adhered to the roller surface of the adhesive pulling roller 511 and is wound by the adhesive pulling roller 511, the tenth driving member 514 drives the pressing block 515 to clamp the adhesive pulling roller 511, so that the adhesive pulling roller 511 cannot rotate any more, and the single-sided adhesive cannot fall off from the adhesive pulling roller 511 in the subsequent process of separating from the single-sided adhesive end holding member 505 along the second direction. When the single-sided adhesive roll 511 needs to be placed on the first suction member 527 to flatten the wound single-sided adhesive, the tenth driving member 514 drives the pressing block 515 to loosen the single-sided adhesive roll 511, and the single-sided adhesive roll 511 can freely rotate, so that the single-sided adhesive adhered and wound on the roll surface of the single-sided adhesive roll 511 can be flattened, and the flatness when the single-sided adhesive is adhered to a material belt in the following process is ensured.

As shown in fig. 24, the single-sided adhesive is conveyed from the single-sided adhesive discharging member 504 to the single-sided adhesive end holding member 505, and a clamping block 516 is further disposed between the single-sided adhesive discharging member 504 and the single-sided adhesive end holding member 505 on the single-sided adhesive conveying path, and the clamping block 516 is driven by an eleventh driving member 517 to clamp the single-sided adhesive or release the single-sided adhesive.

More specifically, the eleventh driver 517 may be a jaw cylinder and the clamp block 516 may be a pair of jaws of the jaw cylinder. Alternatively, the eleventh driving member 517 may be another power source, and the clamping blocks 516 may be a pair of sliding blocks, and may be driven by the eleventh driving member 517 to move toward or away from each other. Before the first cutter 513 cuts off the single-sided adhesive tape, the eleventh driving member can drive the clamping block 516 to clamp the single-sided adhesive tape, so that the single-sided adhesive tape can be ensured not to be pulled out of a new section by the first cutter 513 when cut off, the single-sided adhesive tape is always kept flat, and the overlong single-sided adhesive tape is avoided when the adhesive tape is adhered subsequently.

As shown in fig. 24, on the single-sided tape conveying path, a tensioning roller 518 is further disposed between the single-sided tape discharging member 504 and the clamping block 516, the tensioning roller 518 is mounted on a third moving plate 519, the third moving plate 519 is slidably matched with the mounting plate 503, and a first elastic member 520 is disposed between the third moving plate 519 and the mounting plate 503 to provide a tensioning force.

More specifically, on the single-sided tape conveying path, the tensioning roller 518 needs to be bypassed, and the tensioning roller 518 depends on the tensioning force of the first elastic element 520 to always keep the single-sided tape in a tensioning state, so that the single-sided tape is smooth and can not be wrinkled, and the quality of subsequent splicing tapes is improved.

As shown in fig. 1, on the single-sided adhesive tape conveying path, a first passing roller 521 and a second passing roller 522 are provided upstream and downstream of the tension roller 518, respectively. The two passing rollers are used for changing the conveying direction of the single-sided adhesive, so that the single-sided adhesive is ensured to be as flat as possible between the single-sided adhesive end part holding piece 505 and the adhesive pulling roller 511.

As shown in fig. 24, this embodiment shows a single-sided adhesive end holder 505 that is adsorptive. The single-sided tape end holder 505 is provided with a first adsorption hole 523, and the first adsorption hole 523 is used for adsorbing the single-sided tape, so that the single-sided tape end is held on the single-sided tape end holder 505.

More specifically, the first suction hole 523 may be connected to a negative pressure mechanism, so that the single-sided adhesive is sucked on the single-sided adhesive end holder 505 by forming a negative pressure in the vicinity of the first suction hole 523.

As shown in fig. 27, the tape splicing assembly 501 of this embodiment includes a twelfth driving element 524, where the twelfth driving element 524 can drive the rubberizing element 525 to turn over, so that the first absorbing element 527 is in a glue state or in a tape splicing state.

More specifically, the twelfth driving member 524 may drive the rubberizing member 525 to turn by hinging a piston rod of the air cylinder to the rubberizing member 525, and may also drive the rubberizing member 525 to turn by connecting an output shaft of the motor to the rubberizing member 525. In fig. 24 and 27, the first suction attachment member 527 is in a glue ready state in which the glue ready assembly 502 is capable of placing a length of single side glue on the first suction attachment member 527, while the second suction attachment member 526 is capable of sucking the working tape 203 and/or the standby tape 204. After the twelfth driving element 524 drives the rubberizing element 525 to turn over, the first absorbing element 527 is in a tape-receiving state, at this time, the first absorbing element 527 faces the third direction, at this time, the second absorbing element 526 of the opposite other rubberizing mechanism 500 absorbs the tail end of the working tape and the head end of the standby tape, and the first absorbing element 527 of one rubberizing mechanism 500 is close to the second absorbing element 526 of the other rubberizing mechanism 500, so that the single-sided tape adheres the tail end of the working tape and the head end of the standby tape together.

From the above description, the glue preparation, material absorption and adhesive material adhesion mechanisms in this embodiment do not need to be manually participated, and have high automation degree and high tape connection efficiency, and can realize glue preparation and glue adhesion by means of overturning the glue adhesion member 525, so that the occupied space is small.

As shown in fig. 24, in the gel-prepared state of the first suction member 527, the suction surface of the first suction member 527 is flush with the suction surface of the single side gel end section holder 505 of the gel-prepared assembly 502. In this context, the level may mean that the suction surface of the first suction member 527 is in the same plane as the suction surface of the single-sided tape end holder 505, or that the suction surface of the first suction member 527 is slightly higher or lower than the suction surface of the single-sided tape end holder 505, for example, the suction surface of the first suction member 527 is 1mm, 3mm higher or 1mm, 3mm lower than the suction surface of the single-sided tape end holder 505, and such a difference in height falls within an allowable error range, and may be regarded as the level of both suction surfaces. The two adsorption surfaces are flush, so that single-sided adhesive tape can be ensured to be smoother, and the intercepting length is more accurate.

As shown in fig. 24, the first absorbing member 527 is provided with a second absorbing hole 528, the second absorbing hole 528 is used for absorbing single-sided adhesive tape, the second absorbing member 526 is provided with a third absorbing hole 508, and the third absorbing hole 508 is used for absorbing material strips. The second adsorption hole 528 and the third adsorption hole 508 have the same operation principle as the first adsorption hole 523, and thus will not be described in detail.

As shown in fig. 24 and 28, the second adsorbing member 526 includes a fourth adsorbing block 5261 and a fifth adsorbing block 5262 which are spaced apart from each other, the fourth adsorbing block 5261 is connected to a third vacuumizing device (not shown), the fifth adsorbing block 5262 is connected to a fourth vacuumizing device (not shown), and the third vacuumizing device and the fourth vacuumizing device can independently operate.

More specifically, the fourth adsorption mass 5261 and the fifth adsorption mass 5262 are provided with adsorption holes, the fourth adsorption mass 5261 is connected with a third vacuumizing device (not shown), the fifth adsorption mass 5262 is connected with a fourth vacuumizing device (not shown), and the third vacuumizing device and the fourth vacuumizing device can work independently, that is, the third vacuumizing device or the fourth vacuumizing device can work independently, and can work simultaneously, so that the fourth adsorption mass 5261 and the fifth adsorption mass 5262 can generate adsorption force respectively, or generate adsorption force simultaneously.

The whole process of preparing glue from the glue preparation component 502 to the tape connecting component 501 is as follows:

The single-sided tape end portion of the single-sided tape is adsorbed by the first adsorption hole 523 of the single-sided tape end portion holder 505, and the first adsorption member 527 of the tape applying member 525 is flush with the single-sided tape end portion holder 505 in a standby state. The seventh driving member 506 drives the first moving plate 507 to move in the second direction so that the glue pulling roller 511 approaches the single-sided tape end holder 505. After the glue roller 511 reaches above the single-sided tape end holder 505, the eighth driving member 509 drives the second moving plate 510 to move in the first direction so that the glue roller 511 abuts against the single-sided tape end on the single-sided tape end holder 505. Then, the seventh driving member 506 continues to drive the first moving plate 507 to move along the second direction, and the first moving plate is closer to the clamping block 516, the glue pulling roller 511 rotates, the single-sided glue is adhered to the roller surface of the glue pulling roller 511, and the glue pulling roller 511 winds a section of single-sided glue. The press block 515 then clamps the pull roll 511 against rotation. Then, the single-sided tape end holder 505 is no longer attracted to the single-sided tape end, and the eighth driving member 509 drives the second moving plate 510 away from the single-sided tape end holder in the first direction, so that the pulling roller 511 is also away from the single-sided tape end holder 505. Then, the seventh driving member 506 drives the first moving plate 507 away from the single-sided tape end holding member 505 in the second direction, the single-sided tape discharging member 504 rotates, and the single-sided tape is pulled out by a length. After the first moving plate 507 reaches the predetermined position, the eighth driving member 509 drives the second moving plate 510 in the first direction to approach the single-sided tape end holder 505, and the first suction member 527 of the rubberizing member 525 and the single-sided tape end holder 505 work to suck the single-sided tape. The tenth driving member 514 drives the pressing block 515 to release the glue pulling roller 511, the glue pulling roller 511 can rotate, and the single-sided adhesive tape stuck on the roller surface is flattened onto the first suction member 526. Then, the clamping block 516 clamps the single-sided adhesive, and the ninth driving member 512 drives the first cutter 513 to cut the single-sided adhesive between the single-sided adhesive end holding member 505 and the adhesive applying member 525, so that a length of single-sided adhesive can be placed on the first suction member 527 while a new single-sided adhesive end is sucked onto the single-sided adhesive end holding member 505. Finally, the eighth drive member 509 drives the second moving plate 510 away from the single-sided tape end holder 505 in the first direction into the next standby cycle.

As shown in fig. 3, 24, 27 and 28, the automatic reel changer 100 in the present embodiment includes: the first unwind shaft 101, the second unwind shaft 102, the first unwind shaft 101 and the second unwind shaft 102 are used to load the roll 205. Wherein one of the first unwind spool 101 and said second unwind spool 102 is used for loading the work rolls 201 while the other is used for loading the standby rolls 202. Two rubberizing mechanisms 500 are oppositely disposed, one of which is labeled as a first rubberizing mechanism 529 and the other labeled as a second rubberizing mechanism 530 for clarity of description.

The tape receiving assembly 501 of the second rubberizing mechanism 530 is further provided with a second cutter 531, and the tape receiving assembly 501 of the first rubberizing mechanism 529 and the tape receiving assembly 501 of the second rubberizing mechanism 530 can be close to each other, so that the working tape absorbed by the second absorbing member 526 is cut by the second cutter 531, or the second cutter 531 can also cut the spare tape. The single-sided tape absorbed by the first absorbing member 527 of the second rubberizing mechanism 530 can bond the tail end of the working tape 203 and the starting end of the spare tape 204 together in a state in which the second absorbing member 526 of the first rubberizing mechanism 529 absorbs the tail end of the working tape and the starting end of the spare tape.

More specifically, the first rubberizing mechanism 529 is disposed opposite to the second rubberizing mechanism 530, which means that when the rubberizing members 525 of the first rubberizing mechanism 529 are in a rubberized state, the rubberizing members 525 of the second rubberizing mechanism 530 are also in a rubberized state, the two second adsorbing members 526 are opposite in the third direction. The first direction, the second direction and the third direction are intersected in pairs. The automatic reel changing device in the embodiment does not need manual glue preparation, realizes automatic tape connection, and improves reel changing efficiency.

As shown in fig. 27, the automatic reel changer 100 further includes a fourth moving plate 103 and a thirteenth driving member 105, the tape receiving assembly 501 of the first rubberizing mechanism 529 is mounted on the fourth moving plate 104, and the thirteenth driving member 105 drives the fourth moving plate 104 to move to approach or separate from the tape receiving assembly 501 of the second rubberizing mechanism 530; and/or, the automatic reel changer 100 further includes a fifth moving plate 106 and a fourteenth driving member 107, the tape receiving assembly 501 of the second rubberizing mechanism 530 is mounted on the fifth moving plate 106, and the fourteenth driving member 107 drives the fifth moving plate 106 to move to approach or separate from the tape receiving assembly 501 of the first rubberizing mechanism 529, so that the thirteenth driving member 105 and the fourteenth driving member 106 can drive the first rubberizing mechanism 529 and the second rubberizing mechanism 530 to approach or separate from each other.

More specifically, after the single-sided adhesive is placed on the first suction attachment 527 of the tape splicing assembly 501 by the standby adhesive assembly 502, the tape splicing assemblies 501 of the first and second adhesive mechanisms 529 and 530 can be driven individually or together to approach or separate from each other, so that the second cutter 531 can cut the tape, and adhere the single-sided adhesive to the tail end of the working tape and the beginning end of the standby tape, and the standby roll 202 is converted into the working roll to continue unreeling the tape.

As shown in fig. 27 and 28, the tape receiving assembly 501 of the second rubberizing mechanism 530 in this embodiment further includes a second elastic member 532, and the second elastic member 532 enables the rubberizing member 525 to extend to shield the second cutter 531 or enables the rubberizing member 501 to retract to expose the second cutter 531 when being pressed.

Next, an automatic reel change process of the automatic reel changer in the first embodiment of the present application will be described with reference to fig. 1 to 8, and fig. 15 to 28.

As shown in fig. 3, 4 and 15, the first unwinding shaft 101 is rotating to unwind the work ribbon 203, and the work ribbon 203 is being conveyed toward a winding needle (not shown) to perform cell winding. The second unwinding shaft 102 is loaded with the standby roll 202, and after the second unwinding shaft 102 rotates clockwise until the sealing compound 206 of the standby roll 202 enters the detection range of the first sensor 304, the first sensor 304 can detect the beginning end position of the working tape 204 on the standby roll 202 by identifying the sealing compound 206. Or by controlling the angle of rotation of the second unwind spool 102 to ensure that the beginning end 207 of the backup tape 204 on the backup roll 202 reaches the beginning station. The first drive member 305 then drives the movable carriage 302 in a direction toward the backup roll 202 (and correspondingly away from the work roll 201), and the second take-off end 307 of the first take-off member 303 picks up the take-off end 207 at the take-off station, as shown in fig. 3. The first drive member 305 then drives the movable carriage 302 in a direction away from the backup roll 202 (and correspondingly toward the work roll 201), the seal gum 206 is torn open, and as the beginning end 207 moves away from the backup roll 202, the second unwind shaft 102 rotates to unwind the backup tape 204, the first take-out member 303 pulls the backup tape 204 out until the first take-out member 303 reaches the transfer station, as shown in fig. 4.

As shown in fig. 4, 5 and 28, the first material taking member 303 and the second material taking member 401 each reach the transfer station, and the second material taking member 401 picks up the leading end 207 of the standby tape 204 from the first material taking member 303. The first tape receiving member 501 of the first tape sticking mechanism 529 and the first tape receiving member 501 of the second tape sticking mechanism 529 are brought close to each other, the second cutter 531 cuts the work material tape 203, and the fourth suction block 5261 of the second tape sticking mechanism 530 sucks the tail end of the work material tape 203.

As shown in fig. 6 and 28, the first tape splicing assembly 501 of the first rubberizing mechanism 529 and the first tape splicing assembly 501 of the second rubberizing mechanism 529 are separated from each other, the second material taking member 401 reaches the tape splicing station, more specifically, between the two fourth suction blocks 5261, and then the two tape splicing assemblies 501 are again moved close to each other.

As shown in fig. 7 and 28, the fourth suction block 5261 and the fifth suction block 5262 of the first rubberizing mechanism 529 are simultaneously operated, the second picking member 401 stops the suction operation, and the spare belt 204 is sucked to the second suction member 526. The two splicing assemblies 501 are then moved away from each other and the second material take-off 401 exits the splicing station.

As shown in fig. 8 and 28, the tape receiving assembly 501 of the first rubberizing mechanism 529 is close to the tape receiving assembly 501 of the second rubberizing mechanism 530 again, the second cutter 531 cuts off the spare tape 204 by a section, the fifth adsorption block 5262 of the first rubberizing mechanism 529 stops adsorbing, the fifth adsorption block 5262 of the second rubberizing mechanism 530 starts adsorbing, and thus the new starting end 207 of the spare tape 204 is adsorbed onto the fifth adsorption block 5262 of the second rubberizing mechanism 530. Thus, the tail end of the working tape 203 and the head end of the standby tape 204 are both sucked by the second rubberizing mechanism 530. Because the second cutter 531 is fixed to the cutting position of the spare material belt, so the distance between the tail end of the working material belt and the starting end of the spare material belt is also fixed, the distance between the tail end and the starting end can be regarded as equal to the thickness of the second cutter 531, the follow-up joint belt can be more accurate, and the product consistency is good.

As shown in fig. 27 and 28, the twelfth driving member 524 of the first rubberizing mechanism 529 drives the rubberizing member 525 to turn over, the single-sided adhesive prepared on the first absorbing member 527 of the first rubberizing mechanism 529 faces the third direction, the fourth absorbing block 5261 of the first rubberizing mechanism 529 stops absorbing, and the cut section of the standby tape 204 falls into the waste box 108. The two tape splicing assemblies 501 are then brought closer together again, and the single side adhesive provided on the first suction member 527 of the first rubberizing mechanism 529 adheres the trailing end of the working tape 203 and the leading end 207 of the standby tape 204, which are sucked by the second rubberizing mechanism 530, together.

Next, the two tape splicing assemblies 501 are moved away from each other again, and the twelfth driving member 524 of the first rubberizing mechanism 529 drives the rubberizing member 525 to turn over, and the tape splicing state is restored. Then, the two tape splicing members 501 are brought close to each other again, the fourth and fifth suction blocks 5261 and 5262 of the first rubberizing mechanism 529 are operated, the fourth and fifth suction blocks 5261 and 5262 of the second rubberizing mechanism 530 are not operated any more, and the fourth and fifth suction blocks 5261 and 5262 of the first rubberizing mechanism 529 suck the work material tape 203 and the spare material tape 204. Then, the two tape splicing assemblies 501 are separated from each other again, the twelfth driving member 524 of the second rubberizing mechanism 530 drives the rubberizing member 525 to turn over, the single-sided tape prepared on the first absorbing member 527 of the second rubberizing mechanism 530 faces the third direction, then, the two tape splicing assemblies 501 are separated from each other again, and the single-sided tape prepared on the first absorbing member 527 of the second rubberizing mechanism 530 adheres the tail end of the working tape 203 absorbed by the second rubberizing mechanism 530 and the head end 207 of the spare tape 204 together. Thus, both sides of the working tape 203 and the standby tape 204 are adhered with single-sided adhesive tape. Finally, the two tape receiving assemblies 501 are separated from each other again, the first rubberizing mechanism 529 does not adsorb the material tape any more, the standby material roll 204 continues to unreel the material tape for cell winding, and at the moment, the standby material roll 204 becomes a working material roll, and the roll replacement is completed.

In practical application, the second material taking member 401 can also transfer the starting end 207 of the spare material belt 204 between the two fifth adsorption blocks 5262 as shown in fig. 28, and at this time, the spare material belt 204 does not need to be cut off, so that the raw material cost is saved.

Next, an automatic reel changing process of the automatic reel changing apparatus 100 according to another embodiment of the present application will be described with reference to fig. 9 to 28.

As shown in fig. 9, since the second unwinding shaft 102 drives the standby roll 202 to rotate counterclockwise, the first pick-up member 303 picks up the leading end 207, and the leading end 207 is directed downward.

As shown in fig. 10, at the transfer station, the second picking member 401 picks up the head end 207 from the first picking member 303, and the head end 207 is still facing downward.

As shown in fig. 11, in the process of moving the second material taking member 401 from the transferring station to the tape receiving station, the fourth driving member 406 drives the second material taking member 401 to rotate around the axis L of the second material taking member 401, the third material taking end 414 of the pick-up head end 207 is turned from the left side to the right side, the standby tape 204 is turned from the state shown by the solid line to the state shown by the broken line, and the head end 207 faces upward.

As shown in fig. 12, the tape splicing assembly 501 of the first rubberizing mechanism 529 adsorbs the cut work tape 203.

As shown in fig. 13, the tape splicing assembly 501 of the second rubberizing mechanism 530 adsorbs the standby tape 204.

As shown in fig. 14, the cut work tape 203 and the backup tape 204 are both adsorbed to the second adsorbing member 526 of the first rubberizing mechanism 529, and then the first adsorbing member 527 of the second rubberizing mechanism 530 performs rubberizing.

Then, the second rubberizing mechanism 530 adsorbs the work tape 203 and the standby tape 204, and the first adsorbing member 527 of the first rubberizing mechanism 529 performs rubberizing.

As can be seen from the above description, the embodiment shown in fig. 9 to 28 adds a process of rotating the second material taking member 401 during the transferring process, and thus is suitable for the case that the second unwinding shaft 102 rotates counterclockwise. The process for the start-up, cutting, rubberizing, etc. of the strip is similar to the embodiment shown in fig. 3 to 8 and will therefore not be described in detail.

The embodiment of the application also provides a battery cell winding device, which comprises: an automatic reel changer as described above.
