Referring to fig. 1 to 3, a roll changing device 10 according to an embodiment of the present invention includes an unwinding mechanism 100, a fixing mechanism 200, a tape splicing mechanism 300, and a tape adhering mechanism 400.

Unwinding mechanism 100 includes first unwinding assembly 110 and second unwinding assembly 120, and first unwinding assembly 110 and second unwinding assembly 120's structure is the same, all can include unreeling the axle, unreels the axle and is used for installing the material book and unreels output material area downstream, and the material area can be the material area that needs unreel in the production processes such as utmost point ear material area, pole piece material area, and the material area in this embodiment is utmost point ear material area.

A tension adjusting assembly (not shown) and a plurality of rollers (not shown) are generally disposed downstream of the first unwinding assembly 110 and the second unwinding assembly 120, the tension adjusting assembly is configured to buffer or release the material tape in the unwinding process, so as to maintain the tension of the material tape, and the rollers can change the conveying direction of the material tape. Specifically, in the embodiment, the material strips unreeled by the first unreeling assembly 110 and the second unreeling assembly 120 can be conveyed in a substantially horizontal direction after being guided by the rollers, and the surfaces of the material strips are substantially parallel to the horizontal plane.

The material belts unreeled and output by the first unreeling assembly 110 and the second unreeling assembly 120 can alternately serve as the working material belt 21 and the standby material belt 22. That is, when the material tape unreeled and output by the first unreeling assembly 110 is used as the work material tape 21, the material tape unreeled and output by the second unreeling assembly 120 is used as the spare material tape 22; while the first unwinding assembly 110 unwinds the output tape as the spare tape 22, the second unwinding assembly 120 unwinds the output tape as the working tape 21. The working material tape 21 refers to the material tape which is fed downstream after the unwinding mechanism 100 unwinds and is finally cut into sheet materials (e.g., tab sheet materials), and the spare material tape 22 is not fed downstream and is processed temporarily, and is only used as a supplement after the unwinding of the working material tape 21 is completed.

The fixing mechanism 200 includes a first fixing assembly 210 and a second fixing assembly 220, the fixing mechanism 200 is located downstream of the unwinding mechanism 100, and the first fixing assembly 210 and the second fixing assembly 220 can respectively fix the material tape unwound and output by the first unwinding assembly 110 and the second unwinding assembly 120. The fixing mechanism 200 may fix the tape by absorption, clamping, or the like. Specifically in this embodiment, the first fixing assembly 210 includes a clamping jaw cylinder and two fixing clamping jaws fixed at the driving end of the clamping jaw cylinder, and the clamping jaw cylinder can drive the two fixing clamping jaws to close or open so as to clamp or release the material belt unreeled and output by the first unreeling assembly 110. The second fixing element 220 has the same structure as the first fixing element 210, and therefore, the description thereof is omitted.

The tape splicing mechanism 300 includes a first cutting assembly 310 and a first positioning assembly 320, the tape splicing mechanism 300 is located at the downstream of the fixing mechanism 200, and the work tape 21 unreeled and output by the unreeling mechanism 100 can sequentially pass through the fixing mechanism 200 and the first positioning assembly 320. The first cutting assembly 310 can cut off the work tape 21 fixed by the fixing mechanism 200 (either the first fixing assembly 210 or the second fixing assembly 220) and the first positioning assembly 320. Specifically, the first cutting assembly 310 generally cuts the work material tape 21 by using a manner of matching an upper cutter and a lower cutter, and the first positioning assembly 320 may also fix the work material tape 21 by using a manner of clamping, adsorbing, and the like. After the work material tape 21 is cut, it is fixed by the first positioning assembly 320.

Moreover, the unwinding mechanism 100 and the fixing mechanism 200 can move back and forth in the first direction relative to the first positioning assembly 320, so that the standby tape 22 fixed by the fixing mechanism 200 (which may be the first fixing assembly 210 or the second fixing assembly 220) is aligned with the working tape 21 fixed by the first positioning assembly 320. The first direction refers to a direction in which two material tapes unreeled by the first unreeling assembly 110 and the second unreeling assembly 120 are spaced apart, that is, an up-down direction shown in fig. 3 or a left-right direction shown in fig. 2.

The fixing mechanism 200 passes through the first position and the second position during the reciprocating movement in the first direction. As shown in fig. 3, when the work material tape 21 unreeled and output by the second unreeling assembly 120 is used, the fixing mechanism 200 is located at the first position, the second fixing assembly 220 is aligned with the first positioning assembly 320, and the work material tape 21 unreeled and output by the second unreeling assembly 120 sequentially passes through the second fixing assembly 220, the first cutting assembly 310 and the first positioning assembly 320 until being transported downstream to a cutting station for slicing.

At this time, the tape on the first unwinding assembly 110 is the spare tape 22. When the material tape on the second unwinding assembly 120 is about to be unwound, the second fixing assembly 220 and the first positioning assembly 320 fix the work material tape 21 at the same time, and the first cutting assembly 310 cuts off the fixed work material tape 21, so as to obtain the work material tape 21 fixed to the first positioning assembly 320. Then, the unwinding mechanism 100 and the fixing mechanism 200 are moved to the second position along the first direction (upward in fig. 3), so that the first fixing element 210 is aligned with the first positioning element 320. At this time, the spare tape 22 unwound by the first unwinding assembly 110 is aligned with the working tape 21 fixed by the first positioning assembly 320. The adhesive applying mechanism 400 applies the adhesive film 30 (as shown in fig. 10) on at least one side (usually two sides) of the aligned spare tape 22 and the working tape 21, wherein one portion of the adhesive film 30 is adhered to the starting end of the spare tape 22, and the other portion is adhered to the cut end of the working tape 21, so as to connect the spare tape 22 unwound by the first unwinding assembly 110 with the original working tape 21 and form a new working tape 21. Then, the first fixing element 210 and the first positioning element 320 respectively release the fixed material belts, so that the first unwinding assembly 110 can unwind the output work material belt 21 downstream. During the process of unwinding the output work tape 21 by the first unwinding assembly 110, a new roll can be loaded on the second unwinding assembly 120 as the spare tape 22.

Referring to fig. 4, in the embodiment, the tape splicing mechanism 300 further includes a first driving member 330, and the first driving member 330 is in transmission connection with the first cutting assembly 310 and can drive the first cutting assembly 310 to approach or depart from the tape between the first positioning assembly 320 and the fixing mechanism 200.

To ensure a more orderly operation of the roll changing device 10, the first driving member 330 drives the first cutting assembly 310 to move in a first direction, which is the same as the moving direction of the fixing mechanism 200. When the first cutting assembly 310 cuts the work tape 21 fixed by the fixing mechanism 200 and the first positioning assembly 320, the work tape 21 can be moved away from the first driving member 330, so as to expose the cut end of the work tape 21 and avoid the gluing track of the gluing mechanism 400, thereby preventing the gluing mechanism 400 from being unable to smoothly glue the spare tape 22 and the work tape 21 due to the shielding of the first cutting assembly 310.

It should be noted that, in a normal working state, the material belt between the first positioning assembly 320 and the fixing mechanism 200 is the working material belt 21; during the roll change, the tape between the first positioning assembly 320 and the fixing mechanism 200 includes both the working tape 21 and the spare tape 22.

Similarly, when the material tape on the first unwinding assembly 110 is about to be unwound as the working material tape 21, the first fixing assembly 210 and the first positioning assembly 320 fix the current working material tape 21 at the same time, and the fixed working material tape 21 is cut by the first cutting assembly 310. Then, the unwinding mechanism 100 and the fixing mechanism 200 are moved to a first position along a first direction (downward in fig. 3) relative to the first positioning assembly 320, so that the second fixing assembly 220 is aligned with the first positioning assembly 320. At this time, the second unwinding assembly 120 unwinds the output standby material tape 22 to align with the working material tape 21 fixed by the first positioning assembly 320. The adhesive tape 30 is attached to at least one side of the aligned standby tape 22 and the working tape 21 by the adhesive attaching mechanism 400, so that the standby tape 22 unwound by the second unwinding assembly 120 can be connected to the original working tape 21 to form a new working tape 21. Then, the second fixing assembly 220 and the first positioning assembly 320 respectively release the fixed material belts, and the second unwinding assembly 120 can unwind the output work material belt 21 downstream. While the second unwinding assembly 120 unwinds the output work tape 21, the first unwinding assembly 110 can be loaded with a new roll as a spare tape 22.

In this way, the first unwinding assembly 110 and the second unwinding assembly 120 alternately unwind the working material tape 21, and the automatic tape change is realized after the working material tape 21 is unwound. During the roll changing process, the first positioning assembly 320 always keeps fixed to the original working tape 21, and the fixing mechanism 200 keeps fixed to the spare tape 22, so as to ensure that the working tape 21 and the spare tape 22 are reliably aligned.

In this embodiment, the fixing mechanism 200 is fixedly connected to the unwinding mechanism 100, so that the first unwinding assembly 110 and the second unwinding assembly 120 can move synchronously along the first direction along with the fixing mechanism 200. In this way, the relative positions of the first and

second unwinding assemblies

110 and 120 and the first and second fixing assemblies 210 and 220 may be maintained. In the process of changing the roll, when the unwinding mechanism 100 and the fixing mechanism 200 move back and forth along the first direction, the synchronism is better.

Referring to fig. 1 and fig. 2 again, in the present embodiment, the roll-changing device 10 further includes a bottom plate 600 and a transmission mechanism 700. Moreover, the unwinding mechanism 100 further includes a moving plate 130, the moving plate 130 is slidably mounted on the bottom plate 600 along a first direction, and the first unwinding assembly 110, the second unwinding assembly 120 and the fixing mechanism 200 are all mounted on the moving plate 130.

The transmission mechanism 700 may adopt a cylinder, an electric cylinder, or a motor (used in cooperation with a matching threaded lead screw pair), and the transmission mechanism 700 can drive the moving plate 130 to slide along the first direction, so as to drive the fixing mechanism 200 to move between the first position and the second position. It can be seen that, when the transmission mechanism 700 drives the fixing mechanism 200 to move along the first direction, the first unwinding assembly 110 and the second unwinding assembly 120 will also move synchronously along with the moving plate 130 along the first direction.

The base plate 600 can be used to fixedly attach to other equipment, such as a large plate of a winder, and the splicing mechanism 300 can also be mounted to the base plate 600. Specifically, in the present embodiment, the unwinding mechanism 100 further includes a vertical plate 140, the vertical plate 140 is mounted on the moving plate 130 and extends along a direction perpendicular to the surface of the bottom plate 600, and the first unwinding assembly 110 and the second unwinding assembly 120 are both disposed on the vertical plate 140. As can be seen, the unwinding mechanism 100 can reasonably utilize the space above the bottom plate 600, so that the structure of the reel changing device 100 is more compact.

In addition, the unwinding mechanism 100 is disposed at one end of the bottom plate 600 along a second direction, which is perpendicular to the first direction and refers to the left and right direction shown in fig. 1. The tape splicing mechanism 300 and the unwinding mechanism 100 are disposed at an interval in the second direction, and the tape splicing mechanism 300 and the tape splicing mechanism 400 are disposed at an interval in the first direction. Therefore, the space above the bottom plate 600 can be fully utilized, thereby making the structure of the roll-changing device 100 more compact.

Referring to fig. 3 again, in the present embodiment, the tape splicing mechanism 300 further includes a second positioning element 340 and a second cutting element 350, the second positioning element 340 is located on one side of the first positioning element 320 in the first direction and is spaced apart from the first positioning element 320, and the second cutting element 350 is disposed upstream (on the left side in fig. 2) of the second positioning element 340.

When the securing mechanism 200 is routed through the first position, in addition to the second securing member 220 being aligned with the first positioning member 320, the first securing member 210 will also be aligned with the second positioning member 340. At this time, the standby material tape 22 unreeled by the first unreeling assembly 110 sequentially passes through the second cutting assembly 350 and the second positioning assembly 340, and the second cutting assembly 350 can cut off the standby material tape 22 jointly fixed by the first fixing assembly 210 and the second positioning assembly 340.

It can be seen that, before the reel change is performed, the spare tape 22 unwound from the first unwinding assembly 110 is also cut off, so as to form the spare tape 22 fixed to the first fixing assembly 210. In this manner, precise control of the length of the backup tape 22 extending from the first fastening assembly 210 is facilitated. When the fixing mechanism 200 moves to the second position to prepare for roll change and the first fixing assembly 210 is aligned with the first positioning assembly 320, the backup tape 22 fixed by the first fixing assembly 210 can be better matched with the working tape 21 fixed by the first positioning assembly 320, that is, the starting end of the backup tape 22 is coplanar with the cut end of the working tape 21, so that the adhesive attaching mechanism 400 can smoothly attach the film 30.

Further, the splicing mechanism 300 further comprises a third positioning component 360 and a third cutting component 370. Furthermore, a third positioning member 360 is disposed on a side of the first positioning member 320 opposite to the second positioning member 340 and spaced apart from the first positioning member 320, and a third cutting member 370 is disposed upstream of the third positioning member 360. That is, the third positioning element 360 and the second positioning element 340 are respectively located at two sides of the first positioning element 320 in the first direction, i.e., at the upper and lower sides shown in fig. 3.

When the securing mechanism 200 is routed through the second position, in addition to the first securing member 210 being aligned with the first positioning member 320, the second securing member 220 will also be aligned with the third positioning member 360. At this time, the spare tape 22 unwound by the second unwinding assembly 120 sequentially passes through the third cutting assembly 370 and the third positioning assembly 360, and the third cutting assembly 370 can cut off the spare tape 22 jointly fixed by the second fixing assembly 220 and the third positioning assembly 360.

Similarly, before the reel change is performed, the backup tape 22 unwound by the second unwinding assembly 120 is cut, so as to form the backup tape 22 fixed to the second fixing assembly 220. In this way, the length of the backup tape 22 extending from the second fastening component 220 can be consistent with the length of the backup tape 22 extending from the first fastening component 210. When the fixing mechanism 200 moves to the first position to prepare for roll change and the second fixing element 220 is aligned with the first positioning element 320, the spare tape 22 fixed by the second fixing element 220 can better match with the working tape 21 fixed by the first positioning element 320, thereby facilitating the gluing mechanism 400 to apply the film 30.

Referring to fig. 5, in the present embodiment, the second cutting assembly 350 includes an upper blade 351, a lower blade 352 and a cutting driving member 353, the spare tape 22 unwound and outputted by the first unwinding assembly 110 is supported by the lower blade 352 when passing through the second cutting assembly 350, and the lower blade 352 is located at a side of the upper blade 351 facing away from the second positioning assembly 340.

Specifically, the upper blade 351 is disposed opposite to the lower blade 352, and the spare tape 22 drawn to the second positioning assembly 350 passes between the upper blade 351 and the lower blade 352. The upper knife 351 may be connected to a driving end of a cutting driving member 353, and the cutting driving member 353 is generally an air cylinder, and cuts off the backup tape 22 supported by the lower knife 352 by driving the upper knife 351 to move relative to the lower knife 352.

Moreover, since the lower blade 352 is located on the side of the upper blade 351 facing away from the second positioning assembly 340, the lower blade 352 is located on the upstream side of the upper blade 351, i.e., the right side as viewed in fig. 3. Therefore, when the spare tape 22 is cut, the supporting surface (upper surface) of the lower blade 352 can support the starting end of the spare tape 22, thereby preventing the starting end of the spare tape 22 from being raised.

Further, in the embodiment, the second positioning assembly 340 includes a supporting plate 341, a pressing rod 342 and an elastic member 343, and the pressing rod 342 can press the backup tape 22 against the supporting surface of the supporting plate 341 under the action of the elastic member 343. Also, the lower blade 352 is fixedly coupled to the support plate 341, and a support surface of the lower blade 352 is flush with a support surface of the support plate 341.

When the first fixing assembly 210 is aligned with the second positioning assembly 340, the spare tape 22 unwound from the first unwinding assembly 110 can be guided into the second positioning assembly 340 by manual traction and fixed, so that the first fixing assembly 210 and the second positioning assembly 340 can jointly fix the spare tape 22. The support plate 341 can support the backup tape 22. When the spare tape 22 is pulled, the pressing rod 342 can be manually lifted to make the pressing rod 342 be away from the supporting plate 341, and after the spare tape 22 passes through the lower part of the pressing rod 342, the pressing rod 342 is released, so that the pressing rod 342 can be abutted against the supporting surface of the supporting plate 341 under the action of the elastic member 343 to press the spare tape 22.

Since the lower knife 352 can be fixedly mounted on the supporting plate 341, that is, the second cutting assembly 350 and the second positioning assembly 340 can share the supporting plate 341, the structure of the splicing mechanism 300 can be simplified to a certain extent, so that the structure of the roll-changing device 10 is more compact. When the backup tape 22 is cut, the supporting surface of the supporting plate 341 and the supporting surface of the lower blade 352 can support the backup tape 22 together and remain stationary, so that the leading end of the backup tape 22 can be prevented from being raised after cutting.

Specifically, the edge of the supporting plate 341 is provided with a curved seat 3412, one end of the curved seat 3412 extends to the upper side of the supporting surface of the supporting plate 341, and the pressing rod 342 slidably penetrates through the curved seat 3412. The elastic member 343 is a compression spring, and the compression spring is sleeved on the compression rod 342 and two ends of the compression spring are respectively abutted against the curved seat 3412 and a head portion (an end facing the surface of the supporting plate 341) of the compression rod 342, so as to provide a downward acting force for the compression rod 342. In addition, in order to facilitate manual lifting of the pressing rod 342, a handle 3421 is further provided at one end of the pressing rod 342 away from the supporting surface of the supporting plate 341.

Further, in the present embodiment, the guide groove 3411 through which the spare tape 22 passes is formed on the surface of the support plate 341. The guide groove 3411 can guide and limit the standby material tape 22, so that accurate traction on the standby material tape 22 is facilitated. Specifically, two oppositely disposed guide blocks (not shown) are disposed on the supporting plate 341, so as to form the guide groove 3411. Obviously, in other embodiments, the guide groove 3411 may be integrally formed with the supporting plate 341.

It should be noted that the structure and function of the third positioning element 360 and the third cutting element 370 are substantially the same as those of the second positioning element 340 and the second cutting element 350, and therefore are not described herein again.

Referring to fig. 6 to 8, the gluing mechanism 400 may be mounted on the base plate 600, and the gluing mechanism 400 includes a gluing driving member 410, a suction plate 420 and a swing member 430. Two suction plates 420 are installed at the driving end of the rubberizing driving piece 410, and can be folded or unfolded under the driving of the rubberizing driving piece 410.

The rubberizing driving part 410 can be a clamping jaw air cylinder, and the two suction plates 420 are respectively arranged on two clamping jaws of the clamping jaw air cylinder. The suction plate 420 has an adsorption surface that can adsorb the film 30 by means of negative pressure, electrostatic adsorption, or the like. When the two suction plates 420 are flattened under the driving of the rubberizing driving piece 410, the suction surfaces of the two suction plates 420 are far away from each other to be in a coplanar state or a substantially coplanar state; when the two suction plates 420 are closed under the driving of the rubberizing driving piece 410, the suction surfaces of the two suction plates 420 are close to each other until being attached or close to each other.

Further, the swing component 430 can drive the rubberizing driving component 410 to swing between the glue preparation position and the rubberizing position. Specifically, one end of the rubberizing driving piece 410, which is far away from the suction plate 420, can rotate around the rotating shaft, so that the rubberizing driving piece 410 swings. The axis of rotation of the rubberized drive member 410 is generally perpendicular to the first direction and may extend in the left-right direction as shown in fig. 6. Compared with the gluing position, the glue preparing position is far away from the material belt between the fixing mechanism 200 and the first positioning component 320. In the standby position, the film 30 for connecting the standby tape 22 and the work tape 21 may be loaded onto at least one of the suction plates 420. In the gluing position, the gluing driving member 410 can drive the suction plate 420 to adhere the adhered film 30 to the surfaces of the aligned standby tape 22 and the working tape 21.

Specifically, when the swing assembly 430 drives the rubberizing driving element 410 to swing to the glue preparation position, the rubberizing driving element 410 can drive the two suction plates 420 to be flattened. At this time, since the suction surfaces of the two suction plates 420 face upward and are substantially horizontal, the film 30, which is stored in advance or prepared in real time by another mechanism, can be smoothly received and sucked by the suction surfaces of the suction plates 420.

After the feeding of the film 30 on the suction plates 420 is completed, the two suction plates 420 are still kept flat, and the swing assembly 430 drives the rubberizing driving member 410 to swing to the rubberizing position. At this time, the two suction plates 420 are respectively located on the upper side and the lower side of the aligned spare tape 22 and the working tape 21. When the rubberizing driving element 410 swings from the glue preparation position to the rubberizing position, it needs to swing approximately 90 degrees, so that the absorption surfaces of the two absorption plates 420 are switched from the horizontal state to the approximately vertical state, and one of the absorption plates 420 is located above the aligned standby material tape 22 and the aligned working material tape 21, while the other absorption plate 420 is located below the aligned standby material tape 22 and the aligned working material tape 21.

Then, the rubberizing driving member 410 drives the two suction plates 420 to close, and the suction surfaces of the two suction plates 420 approach each other until the cut end of the working tape 21 and the start end of the standby tape 22 are clamped between the two suction plates 420. At this time, the adhesive sheet 30 on the suction surface of the suction plate 420 can be bonded to the start end of the backup tape 22 and the cut end of the work tape 21, thereby connecting the backup tape 22 and the work tape 21. After the pasting is completed, the two suction plates 420 will be flattened again by the driving of the pasting driving member 410 and will return to the glue preparing position by the driving of the swinging assembly 430 to prepare for the next pasting.

It can be seen that the tape pasting mechanism 400 can quickly realize automatic tape pasting, so that the roll changing efficiency of the roll changing device 10 is further improved. Moreover, when the rubberizing mechanism 400 is transferred between the glue preparation position and the rubberizing position, only the rubberizing mechanism needs to swing around the rotating shaft, and linear driving assemblies do not need to be arranged in multiple directions, so that the structure of the rubberizing mechanism 400 can be simplified.

Specifically, in this embodiment, the swing assembly 430 includes a support 431, a swing seat 432, and a swing driving member 433, the swing seat 432 is rotatably installed on the support 431, the rubberizing driving member 410 is fixedly installed on the swing seat 432, and the swing driving member 433 can drive the swing seat 432 to rotate, so that the swing seat 432 drives the rubberizing driving member 410 to swing between the glue preparing position and the rubberizing position.

The support 431 is formed with a U-shaped mounting portion (not shown), and the swing seat 432 can be rotatably mounted in the U-shaped mounting portion of the support 431 by a pin (not shown), thereby ensuring stability during rotation. The rocker 432 can provide a larger mounting area for the rubberized drive 410. Specifically, the swing assembly 430 further includes a connecting rod 434, one end of the connecting rod 434 is fixedly connected to the pin, and the other end is hinged to the movable end of the swing driving member 433. Moreover, the moving end of the swinging driving member 433 can be controlled to extend and retract, and the pin shaft is driven to rotate through the connecting rod 434, so as to drive the swinging seat 432 to rotate. The swing driving member 433 may be a cylinder, and a fixed end thereof may be hinged to the second sliding plate 443 (see fig. 6 and 7) of the transferring assembly 440.

Referring to fig. 1 and fig. 6 again, in the present embodiment, the roll changing device 10 further includes a glue preparing mechanism 500, and the glue preparing mechanism 500 can cut the unwound adhesive tape into the adhesive sheet 30 and transport the adhesive sheet 30 to the surface of the suction plate 420 located at the glue preparing position.

The glue preparation mechanism 500 may also be mounted to the base plate 600. The glue preparing mechanism 500 can prepare the film 30 in real time by using the adhesive tape, so that the reel changing device 10 realizes the integrated operation of glue preparing and sticking, and the manual operation can be further reduced. Moreover, the cut film 30 of the film preparation mechanism 500 can be directly transferred to the surface of the suction plate 420, so that the film 30 does not need to be stored, and the dust sticking to the surface of the film 30 in the storage process can be avoided.

Referring to fig. 9, in the embodiment, the adhesive preparing mechanism 500 includes an adhesive tape unwinding assembly 510, a pulling assembly 520 and a cutting assembly 530.

The tape unwinding assembly 510 may include an unwinding shaft, and the tape unwinding assembly 510 is used to unwind the tape. A tension adjusting assembly (not shown) and a roller (not shown) are generally disposed downstream of the tape unwinding assembly 510, and the tension adjusting assembly can maintain the tension of the tape. The pulling assembly 520 is used for pulling a predetermined length of adhesive tape above the suction plate 420, and the cutting assembly 530 is used for cutting the adhesive tape between the pulling assembly 520 and the adhesive tape unwinding assembly 510 to obtain the adhesive tape 30 carried on the suction plate 420.

It can be seen that each cut of the film 30 by the cutting assembly 530 can be directly received by the suction plate 420, thereby speeding up the feeding of the film 30 and preventing the film 30 from being contaminated.

In addition, the adhesive tape preparing mechanism 500 further includes a supporting base 540 for supporting, and the adhesive tape unwinding assembly 510, the pulling assembly 520 and the cutting assembly 530 are all mounted on the supporting base 540. The supporting base 540 may extend vertically along the surface of the base 600, so that the space above the base 600 can be reasonably utilized, and the structure of the roll-changing device 10 is more compact.

Further, the adhesive preparing mechanism 400 further includes a pressing assembly 560, and the pressing assembly 560 can fix the adhesive tape between the pulling assembly 520 and the adhesive tape unwinding assembly 510 and drive the fixed adhesive tape to move toward the suction plate 420 (i.e., downward in fig. 6), until the adhesive tape above the suction plate 420 is adsorbed by the suction plate 420. That is, the film 30 is sucked by the suction plate 420 before being cut off from the tape, so that the film 30 obtained by cutting the tape by the cutting unit 530 is directly fixed to the suction surface of the suction plate 420, thereby omitting the process of transferring the sheet-like film 30 from the output end of the film preparing mechanism 400 to the suction plate 420 and preventing the film 30 from being contaminated, warped or deflected during the transfer process.

Specifically, in the embodiment, the supporting base 540 is slidably connected with a connecting plate 550 along the vertical direction, and the cutting assembly 530 and the pressing assembly 560 are both mounted on the connecting plate 550. In addition, the pressing assembly 560 includes a pressing cylinder 561, a first clamping jaw 562 and a second clamping jaw 563, the first clamping jaw 562 is fixed at the moving end of the pressing cylinder 561, and the second clamping jaw 563 is arranged below the first clamping jaw 562 and is fixedly connected to the connecting plate 550.

Further, a second connecting seat 570 is slidably connected to one side of the supporting seat 540, which faces away from the connecting plate 550, along the vertical direction, and the second connecting seat 570 is fixedly connected to the connecting plate 550 through a connecting block (not shown). The supporting base 540 is provided with a first cylinder 581, and the moving end of the first cylinder 581 is fixedly connected with a second connecting base 570. The second connecting seat 570 is slidably connected with a moving seat 590 along a horizontal direction, a second air cylinder 582 is arranged on the second connecting seat 570, and a moving end of the second air cylinder 582 is fixedly connected with the moving seat 590.

The pulling assembly 520 includes a pulling cylinder 521, and the pulling cylinder 521 is fixed on the movable base 590. Two moving ends of the traction cylinder 521 are fixedly connected with the third clamping jaw 522 and the fourth clamping jaw 523 respectively. When the adhesive tape is pulled, the third clamping jaw 522 and the fourth clamping jaw 523 clamp the adhesive tape and horizontally move along with the moving seat 590 under the driving of the second air cylinder 582 so as to pull the adhesive tape with a preset length. Then, the first clamping jaw 562 is driven by the pressing cylinder 561 to cooperate with the second clamping jaw 563 to clamp the adhesive tape, and the first cylinder 581 drives the connecting plate 550 to descend, so as to drive the pressing assembly 560 to drive the clamped adhesive tape to move downwards until the adhesive tape pulled by the pulling assembly 520 is adsorbed by the adsorption surface of the adsorption plate 420. Finally, the cutting unit 530 cuts the adhesive tape to obtain the adhesive sheet 30 attached to the suction plate 420.

Referring to fig. 6 and 7 again, in the present embodiment, the adhesive applying mechanism 400 further includes a transferring assembly 440, when the adhesive applying driving member 410 is located at the adhesive preparing position, the transferring assembly 440 can drive the adhesive applying driving member 410 to move along the first direction, so that the two suction plates 420 sequentially pass through the positions capable of receiving the films 30 output by the adhesive preparing mechanism 500.

Since the distance between the two suction plates 420 is large and the position of the film 30 output from the film supply mechanism 500 is generally fixed, the film 30 cannot be simultaneously fed to the surfaces of the two suction plates 420. Specifically, in this embodiment, the position of the film 30 that can receive the output of the film supply mechanism 500 refers to the direction of the output of the film supply mechanism 500. After the transfer assembly 440 is disposed, one of the suction plates 420 can receive the film 30 output by the film preparation mechanism 500, and then the transfer assembly 440 drives the tape driving member 410 to move a certain distance (generally, the distance between the two suction plates 420) along the first direction, so that the other suction plate 420 can also enter the position capable of receiving the film 30 output by the film preparation mechanism 500, and the other suction plate 420 can receive the film 30 output by the film preparation mechanism 500.

It is understood that the glue preparation position includes two positions, namely a first glue preparation sub-position and a second glue preparation sub-position. Taking fig. 7 as an example, the rubberizing driving member 410 entering the glue preparation position is located at the first glue preparation position, so that the upper suction plate 420 receives the film 30 output by the glue preparation mechanism 500; then, the transferring assembly 440 can drive the rubberizing driving member 410 to move upward for a certain distance, so that the rubberizing driving member 410 moves to the second glue preparing position, and the lower suction plate 420 can also receive the film 30 output by the glue preparing mechanism 500.

It should be noted that, in other embodiments, the transferring assembly 440 may be omitted and the output end of the film preparing mechanism 500 may be moved in the first direction, so as to sequentially feed the cut film 30 onto the suction surfaces of the two suction plates 420.

Further, in this embodiment, when the rubberizing driving element 410 is located at the rubberizing position, the transferring assembly 440 can further drive the rubberizing driving element 410 to move along the first direction, so that the two suction plates 420 can clamp the aligned spare tape 22 and the working tape 21 when being folded.

In order to avoid the interference between the rubberizing driving member 410 and the suction plate 420 thereon and the tape between the first positioning member 320 and the fixing mechanism 200 during the process that the swing member 430 drives the rubberizing driving member 410 to swing to the rubberizing position, a large space is reserved between the rubberizing driving member 410 and the tape to be bonded (the working tape 21 fixed by the first positioning member 320 and the spare tape 22 fixed by the fixing mechanism 200) before the rubberizing driving member 410 swings from the spare position to the rubberizing position. Therefore, after the swing assembly 430 drives the rubberizing driving member 410 to swing to the rubberizing position, the distance between the suction plate 420 and the tape to be bonded may be too large to smoothly complete the rubberizing. At this time, the transferring assembly 440 can drive the tape attaching driving member 410 to be close to the tape to be attached, so as to ensure that the tape attaching mechanism 400 can smoothly complete the tape attaching.

In addition, in this embodiment, the transferring assembly 440 includes a first transferring structure (not shown) and a second transferring structure (not shown), the first transferring structure can drive the tape-sticking driving member 410 to move along a first direction, so that the two suction plates 410 sequentially pass through the positions capable of receiving the films 30 outputted by the tape preparing mechanism 500; the second transfer structure can drive the rubberizing driving element 410 to move toward the tape between the first positioning assembly 320 and the fixing mechanism 200 along the first direction, so that the tape between the first positioning assembly 320 and the fixing mechanism 200 can be clamped when the two suction plates 420 are closed.

That is, when the tape attaching driving member 410 is located at the tape preparing position, it can be moved in the first direction by the driving of the first transfer mechanism, and when the tape attaching driving member 410 is located at the tape attaching position, it can be moved in the first direction by the driving of the second transfer mechanism. Therefore, the rubberizing driving member 410 is driven by different transferring structures at different positions, so that the control is more convenient.

Further, specifically, in the present embodiment, the first transfer structure includes a first sliding plate 441 and a first transfer cylinder 442, and the second transfer structure includes a second sliding plate 443 and a second transfer cylinder 444.

The first sliding plate 441 is slidable in the first direction by the first transfer cylinder 442. Specifically, the first sliding plate 441 is slidably attached to the base plate 600 in the first direction by a rail-slider, and the first transfer cylinder 442 is provided on the base plate 600. The second sliding plate 443 is slidably mounted to the first sliding plate 441 in the first direction, and the second transfer cylinder 444 is mounted to the first sliding plate 441 and can drive the second sliding plate 443 to slide in the first direction. The taping driving part 410 is mounted to the second sliding plate 443, and particularly, the support 431 of the taping mechanism 400 is mounted to the second sliding plate 443, so that the taping driving part 410 and the swing assembly 430 as a whole can be moved in the first direction along with the second sliding plate 443.

The first transfer cylinder 442 can drive the first sliding plate 441 to slide along a first direction, so as to drive the two suction plates 420 to sequentially pass through the positions capable of receiving the films 30 output by the film preparation mechanism 500; the second transfer cylinder 444 can drive the second sliding plate 443 to slide along the first direction, so that the rubberizing driving piece 410 moves towards the material belt between the first positioning assembly 320 and the fixing mechanism 200 at the rubberizing position.

Specifically, the first transfer cylinder 442 and the second transfer cylinder 444 generally have different strokes. The stroke of the first transferring cylinder 442 is generally equal to the distance between the two suction plates 420, and the first transferring cylinder 442 reciprocates to drive the two suction plates 420 to sequentially pass through the positions capable of receiving the sheet material output by the glue preparing mechanism 500. Therefore, after the first transfer cylinder 442 and the second transfer cylinder 444 are determined to have appropriate strokes, the first transfer cylinder 442 and the second transfer cylinder 444 reciprocate according to a certain rule, so that the glue preparation and sticking processes can be smoothly performed, and the control is more convenient.

It should be noted that in other embodiments, the transfer assembly 440 may have other configurations. For example, the transfer assembly 440 employs a motor and a screw pair structure associated with the motor to convert the rotational motion of the motor into a linear motion of the rubberizing driving member 410 in the first direction. By controlling the number of rotations of the motor spindle, it is also possible to drive the two suction plates 420 to sequentially pass through the position capable of receiving the sheet material output by the glue preparation mechanism 500, and to move the rubberizing driving member 410 toward the material belt between the first positioning assembly 320 and the fixing mechanism 200 at the rubberizing position.

In the roll changing device 10, the first unwinding assembly 110 and the second unwinding assembly 120 can unwind the working material tape 21 and the standby material tape 22, when the unwinding of the working material tape 21 of the first unwinding assembly 110 is about to be completed, the first cutting assembly 310 cuts off the working material tape 21 fixed by the fixing mechanism 200 and the first positioning assembly 320, and the standby material tape 22 unwound by the second unwinding assembly 120 can be aligned with the working material tape 21 fixed by the first positioning assembly 320 by moving the fixing mechanism 200 relative to the first positioning assembly 320 along the first direction. Then, the swing assembly 430 drives the rubberizing driving member 410 to swing from the standby position to the rubberizing position, the rubberizing mechanism 400 drives the two suction plates 420 to fold, so as to attach the film 30 to the aligned standby tape 22 and the working tape 21, thereby connecting the standby tape 22 and the working tape 21 to form a new working tape 21, and the first unwinding assembly 110 can be loaded with a new material roll to serve as the standby tape 22. By analogy, the roll changing device 10 can realize automatic roll changing of the material belt, and the roll changing efficiency is high.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
