Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and particularly relates to an automatic roll changing mechanism and a laminating machine. Background Art

[0002] In the existing battery manufacturing process, the material strip unwinding process is one of the important links. During the unwinding process of the material strip (such as electrode, diaphragm), when the old material strip is used up, it needs to be replaced with a new one. Moreover, it is usually necessary to use adhesive paper (or tape) to connect the tail end of the old material strip and the head end of the new material strip to achieve a continuous supply of the material strip.

[0003] At present, an automatic roll-changing device is generally configured in the stacking machine to automatically complete the work of changing and splicing the new and old material tapes. However, when using the existing automatic roll-changing device, the staff follows the following steps to feed the tape: first, the material tape is placed and fixed, and then the material tape and the preparation tape are cut at the same time by the cutting module, and the cut waste is taken away manually. Then, the interface between the material tape and the preparation tape is glued by the gluing mechanism. In this way, the gluing mechanism is directly opposite to the interface, the space is narrow, and it is difficult for humans to place the tape manually. At the same time, the structure and control steps are complicated. Therefore, the prior art has the disadvantages of cumbersome and inconvenient glue preparation operation, low work efficiency, complex structure and high cost. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Reference Figures 1 to 4, several embodiments of the automatic roll changing mechanism and stacking machine of the utility model are given below.

[0038] like Figures 1 to 4 As shown, the first embodiment of the utility model provides an automatic roll-changing mechanism, which has the advantages of simple structure, low manufacturing cost and operating cost, easy loading of new material strips and high working efficiency. It can be assembled into a stacking machine to complete the unwinding and roll-changing and splicing of material strips 110 such as diaphragms, pole pieces, etc.

[0039] The automatic roll changing mechanism of this embodiment has a first direction, a second direction and a third direction, wherein the first direction, the second direction and the third direction are perpendicular to each other. In this embodiment, for the convenience of illustration, it is assumed that the first direction is the front-to-back direction, the second direction is the left-to-right direction, and the third direction is the up-down direction.

[0040] The automatic roll-changing mechanism includes a tape splicing assembly 200 , a glue-applying assembly 300 and a tape cutting assembly 400 .

[0041] The tape splicing assembly 200 is provided with a first adsorption surface, which is used for vacuum adsorption of the tape 110. The first adsorption surface can be used to firmly fix the head end of the new tape on the first adsorption surface through vacuum adsorption. Therefore, when installing the new tape, the staff can pull the head end of the new tape and place it directly on the first adsorption surface, and with the help of the negative pressure adsorption effect, the head end of the new tape is tightly attached to the first adsorption surface. Such a design can shorten the installation time of the new tape, reduce the difficulty of installing the new tape, and thus improve work efficiency.

[0042] There are two tape splicing assemblies 200, which can correspond to two material rolls 100 respectively. The two material rolls 100 are respectively a used material roll and a spare material roll. Specifically, the two tape splicing assemblies 200 correspond to the new material tape in the spare material roll and the old material tape in the used material roll respectively. The two tape splicing assemblies 200 are arranged at a certain interval along the first direction, so that a material tape channel can be formed between the two tape splicing assemblies 200. The material tape channel extends along the second direction, and one end of the material tape channel in the second direction is an inlet end, and the other end of the material tape channel in the second direction is an outlet end.

[0043] In some embodiments, the first adsorption surface is located on one side of the tape assembly 200 in the second direction and is disposed close to the adhesive assembly 300. The end of the tape channel close to the first adsorption surface is set as the inlet end, and the inlet end is arranged opposite to the adhesive assembly 300.

[0044] In this embodiment, the right side of the tape splicing assembly 200 is set as the first adsorption surface, and the extension direction of the tape channel is perpendicular to the first adsorption surface. The two tape splicing assemblies 200 are arranged symmetrically in front and back. The right end of the tape channel is the inlet end. The tape 110 bypasses the first adsorption surface of the corresponding tape splicing assembly 200 and enters the tape channel from the inlet end, and finally moves to the left along the tape channel to the next station, such as Figure 1 As shown, the arrow direction is the moving direction of the material strip 110 .

[0045] The two splice assemblies 200 are configured to be able to move closer to or farther from each other along a first direction.

[0046] It can be understood that when the two tape splicing assemblies 200 move along the first direction and close together, the width of the tape channel becomes smaller, so that the tape 110 located in the tape channel is clamped by the two tape splicing assemblies 200. At this time, the distance between the two first adsorption surfaces in the first direction is reduced, and the distance between the new tape and the old tape is reduced so that the new and old tapes can be bonded together by adhesive tape. When the two tape splicing assemblies 200 move away from each other in the first direction, the width of the tape channel becomes larger, so that the tape 110 can move smoothly and stably along the tape channel. At this time, the distance between the two first adsorption surfaces in the first direction increases.

[0047] The adhesive component 300 is provided with a second adsorption surface, which is used for vacuum adsorption of the adhesive tape, and can fix the adhesive tape tightly on the second adsorption surface through vacuum adsorption. Therefore, when placing the new tape, the staff also needs to place the non-stick surface of the adhesive tape directly on the second adsorption surface, and use the negative pressure adsorption effect to make the adhesive tape stably adhere to the second adsorption surface. At this time, the sticky surface of the adhesive tape faces the tape channel, so that the tail end of the old tape and the head end of the new tape can be bonded at the same time later, thereby completing the tape splicing work.

[0048] In this embodiment, the adhesive component 300 is arranged on the right side of the tape assembly 200, and the second adsorption surface is located on the left side of the adhesive component 300. The area of ​​the second adsorption surface is equal to the area of ​​the adhesive tape, so that the entire adhesive tape is covered on the second adsorption surface to complete the positioning of the adhesive tape.

[0049] The adhesive sticking assembly 300 is configured to move along the second direction when the two tape joint assemblies 200 are closed, so as to adhere the adhesive tape to the material tapes 110 on the two first adsorption surfaces.

[0050] It is understandable that when the two tape splicing assemblies 200 are in the closed state, the glue assembly 300 will move along the second direction, so that the adhesive tape on the second adsorption surface can contact the material tapes 110 on the two first adsorption surfaces at the same time, so that the adhesive tape can play a good bonding role, so as to establish a connection relationship between the new material tape and the old material tape, so as to enable automatic roll replacement operation. After the adhesive tape is bonded, the vacuum adsorption effect on the adhesive tape is released. When the two tape splicing assemblies 200 are in the separated state, the glue assembly 300 will move in the opposite direction along the second direction, so that the second adsorption surface is away from the material tape channel, so as to avoid the glue assembly 300 interfering with the supply of the material tape 110, and at the same time, it can free up a certain space for the staff to place the next piece of adhesive tape on the second adsorption surface.

[0051] By cooperating with the glue application assembly 300 and the two tape connection assemblies 200, the automatic roll changing mechanism has no precision requirement on the glue application position.

[0052] There are two tape cutting assemblies 400, which are respectively arranged on opposite sides of the second adsorption surface in the first direction. The tape cutting assembly 400 is used to cut off the old tape, so that the tail end of the old tape and the head end of the new tape are connected by adhesive tape. After the old tape is cut off, the staff can install the next new tape to replace the installation position of the old tape.

[0053] The tape cutting assembly 400 is configured to move along the second direction during adhesive lamination to cut off the material tape 110 on any first adsorption surface.

[0054] It is understandable that the tape splicing assembly 200 is provided with an abutting surface, which is located on the side of the first adsorption surface away from the material tape channel in the first direction, so that the tape cutting assembly 400 moves along the second direction and presses against the abutting surface, thereby completing the tape cutting work. After the adhesive tape is bonded to the new material tape and the old material tape, the tape cutting assembly 400 is activated to allow the tape cutting assembly 400 to cut the old material tape, so that the tail end of the old material tape is connected to the head end of the new material tape through the adhesive tape. When the first adsorption surface of one of the tape splicing assemblies 200 applies an adsorption and fixing effect to the new material tape, the tape cutting assembly 400 will cut the old material tape on the first adsorption surface of the other tape splicing assembly 200. Therefore, in one roll-changing and tape splicing work, only one of the tape cutting assemblies 400 needs to operate.

[0055] The two tape cutting assemblies 400 correspond to the two tape splicing assemblies 200 respectively, and specifically, correspond to the cutting work of the old tapes on the two first adsorption surfaces respectively. Therefore, in the two roll-changing and tape-splicing work, the two tape cutting assemblies 400 can be used to cut the old tapes on the two tape-splicing assemblies 200 in turn, so that the automatic roll-changing mechanism can be compatible with the roll-changing and tape-splicing work of the new tapes on the two tape-splicing assemblies 200, and at the same time, it helps to improve work efficiency.

[0056] In the automatic roll-changing device provided in this embodiment, when it is necessary to change the roll and splice the tape, the two splice assemblies 200 move toward each other along the first direction and move closer together, shortening the distance between the new tape and the old tape. After the two splice assemblies 200 move into place, the tape 110 in the tape channel can be clamped and fixed by the two splice assemblies 200. At this time, there may be a small gap between the head end of the new tape and the old tape, or the head end of the new tape may be in contact with the old tape.

[0057] Then, the adhesive sticking assembly 300 moves along the second direction and approaches the tape splicing assembly 200, so as to simultaneously press the adhesive tape on the second adsorption surface onto the material tapes 110 on the two first adsorption surfaces, so that the head end of the new material tape and the old material tape are connected under the adhesive action of the adhesive tape. Next, the tape cutting assembly 400 moves along the second direction and approaches the tape splicing assembly 200, so as to use the tape cutting assembly 400 to cut the old material tape, thereby completing the automatic reeling and splicing of the new material tape and the old material tape.

[0058] After the reel change and tape splicing work is completed, the glue application assembly 300 and the tape cutting assembly 400 both move in the opposite direction along the second direction to move away from the tape splicing assembly 200. Subsequently, the two tape splicing assemblies 200 move away from each other along the first direction so that the subsequent material tape 110 can continue to be transported to the next station. At the same time, the staff can remove the old material roll and install the new material roll.

[0059] The automatic roll-changing mechanism of the present embodiment adopts the above-mentioned unique structural design, which can achieve the purposes of simple overall structure, reduced cost, simple control, low precision requirement for gluing position, practicality, reliability and good applicability. At the same time, it is convenient to prepare glue, and effectively avoids the problem that when the adhesive tape is manually glued to the material tape, the precision requirement for the gluing position of the material tape is high, and the bonding position of the adhesive tape and the material tape is easily skewed due to operational errors.

[0060] In some embodiments, the tape splicing assembly 200, the glue applying assembly 300 and the tape cutting assembly 400 are directly mounted on the laminating machine. In other embodiments, the automatic roll changing mechanism further includes a mounting seat 700, and the tape splicing assembly 200, the glue applying assembly 300 and the tape cutting assembly 400 are all fixedly connected to the mounting seat 700.

[0061] In some embodiments, Figure 1 and Figure 2 As shown, the structure of the tape splicing assembly 200 includes a tape splicing platform 220 and a first linear driving member 210 .

[0062] The tape splicing platform 220 is provided with a first adsorption surface, which is located on one side of the tape splicing platform 220 in the second direction and is arranged close to the adhesive laminating assembly 300. Specifically, the first adsorption surface of the tape splicing platform 220 is provided with a plurality of first adsorption holes, and the tape splicing platform 220 is provided with a vacuum tube 230, one end of the vacuum tube 230 is connected to all the first adsorption holes, and the other end of the vacuum tube 230 is connected to a vacuum device such as a vacuum pump. When the vacuum device is running, the first adsorption holes form a certain negative pressure, which can vacuum adsorb the new tape.

[0063] In this embodiment, the tape connection platform 220 is a rectangular plate extending in the up-down direction, all the first adsorption holes are arranged in an array, and the first adsorption surface is arranged on the right side of the tape connection platform 220. The tape connection platform 220 is provided with an air passage, all the first adsorption holes are connected to the air passage, and the vacuum tube 230 is connected to the connecting port of the air passage. The vacuum tube 230 is located on the left side of the tape connection platform 220. The two tape connection platforms 220 are arranged symmetrically with respect to the adhesive assembly 300, and the two tape connection platforms 220 can move simultaneously in the front-to-back direction under the driving action to approach or move away from each other.

[0064] The output end of the first linear drive 210 is connected to the tape connection platform 220, and the first linear drive 210 can provide a driving function for the tape connection platform 220. When the first linear drive 210 is running, the output end of the first linear drive 210 can drive the tape connection platform 220 to move along the first direction. It can be understood that the first linear drive 210 can be a linear drive device such as a cylinder, an electric cylinder, a hydraulic cylinder, a linear module, etc., which can drive the tape connection platform 220 to move linearly.

[0065] In this embodiment, the first linear drive member 210 is a telescopic cylinder, and two first linear drive members 210 are provided, and are respectively arranged corresponding to the two belt connection platforms 220. A connecting seat is arranged at the bottom of each belt connection platform 220, and the connecting seat can be installed on the mounting seat 700 through the slide rail slider pair 800, so that the connecting seat can drive the belt connection platform 220 to move smoothly in the front and rear directions. The telescopic cylinder is installed on the mounting seat 700, and the movable rod of the telescopic cylinder is fixedly connected to the connecting seat. The telescopic cylinder is arranged on the side of the belt connection platform 220 away from the material belt channel. When the two telescopic cylinders work at the same time, the two belt connection platforms 220 can move synchronously and quickly.

[0066] Moreover, the two tape connecting platforms 220 are symmetrically arranged front to back about the second adsorption surface. Therefore, after the two tape connecting platforms 220 are moved and closed at the same time, the contact surface between the adhesive tape and the new tape can be made equal to the contact surface between the adhesive tape and the old tape, so that the new tape and the old tape are basically subjected to the same degree of adhesion, thereby avoiding the new tape and the old tape from being easily separated due to the weak adhesive effect on the new tape or the old tape, and failing to complete the continuous transportation and supply of the tape 110.

[0067] Of course, it is not ruled out that only one first linear drive member 210 is used for the two belt connection platforms 220, and the opposite ends of the first linear drive member 210 are respectively connected to two connecting seats, so that the two belt connection platforms 220 can be driven to move linearly at the same time to achieve the two belt connection platforms 220 approaching or moving away from each other.

[0068] In addition, it is not excluded that only one of the belt connecting platforms 220 is driven to move linearly and close to the other belt connecting platform 220 .

[0069] It can be understood that during the process of changing and splicing the tape, the new tape will be adsorbed and fixed by the corresponding first adsorption surface, so that the new tape is tightly attached to the corresponding first adsorption surface. At this time, the old tape can be adsorbed and fixed by the corresponding first adsorption surface, so that the old tape is tightly attached to the corresponding first adsorption surface, so that the adhesive tape can be pressed on the flat new tape and the old tape at the same time.

[0070] Of course, it is not ruled out that the old material tape is not fixed by adsorption. During the adhesive tape pressing process, the old material tape will be pressed against the corresponding first adsorption surface by the force of the adhesive tape.

[0071] In some embodiments, Figures 1 to 4 As shown, the adhesive component 300 and the material tape channel are arranged relative to each other in the second direction. Therefore, the two tape connecting components 200 will move simultaneously to close or move away, and the central axis of the material tape channel passes through the center position of the second adsorption surface. Then, it can be ensured that the bonding part of the adhesive tape and the new material tape is equal to the bonding part of the adhesive tape and the old material tape, so that the connection between the new material tape and the old material tape is more firmly connected and not easy to break, thereby ensuring the continuous supply of the material tape 110.

[0072] The structure of the glue sticking assembly 300 includes a glue sticking platform 330 and a second linear driving member 310 .

[0073] The glue sticking platform 330 is provided with a second adsorption surface, and the second adsorption surface is located on the side of the glue sticking platform 330 close to the material belt channel. Specifically, the second adsorption surface of the glue sticking platform 330 is provided with a plurality of second adsorption holes, and the glue sticking platform 330 is provided with a negative pressure tube, one end of the negative pressure tube is connected to all the second adsorption holes, and the other end of the negative pressure tube is connected to the vacuum device. When the vacuum device is working, the second adsorption holes can generate a certain negative pressure effect, which can exert a certain vacuum adsorption effect on the non-stick surface of the adhesive tape, so that the adhesive tape is tightly attached to the second adsorption surface.

[0074] In this embodiment, the glue-attaching platform 330 is a rectangular plate extending in the up-down direction, the second adsorption surface is a plane, all the second adsorption holes are arranged in an array, and the second adsorption surface is arranged on the left side of the glue-attaching platform 330. The glue-attaching platform 330 is provided with an air channel, all the second adsorption holes are connected to the air channel, and the negative pressure tube is connected to the connection port of the air channel. The negative pressure tube can be arranged on the front side, the rear side or the right side of the glue-attaching platform 330.

[0075] Of course, in some embodiments, it is not excluded that one of the first adsorption surface and the second adsorption surface is set as a circular arc convex surface, and the other is set as a circular arc concave surface, and after the two tape connection platforms 220 are closed, the two first adsorption surfaces are connected and form a larger circular arc surface together, and the circular arc surface can be semicircular when viewed along the third direction, and the circular arc surface can be embedded with the second adsorption surface, so that the adhesive tape on the second adsorption surface can be simultaneously bonded to the material tapes 110 on the two first adsorption surfaces. In addition, it is not excluded that the second adsorption surface is designed as a V-shaped concave surface or a V-shaped convex surface, and the two first adsorption surfaces can be embedded with the second adsorption surface.

[0076] In addition, in other embodiments, it is not excluded that the adhesive laminating platform 330 is designed to be cylindrical and extend along the third direction. In this case, the outer peripheral surface of the adhesive laminating platform 330 is set as the second adsorption surface, so that the entire adhesive tape can be wrapped on the second adsorption surface, so that the adhesive tape is cylindrical as a whole. In addition, the surface opposite to the two tape connection platforms 220 is set as the first adsorption surface, that is, the wall surface of the material tape channel is the first adsorption surface, and the first adsorption surface is a semicircular concave surface. In this case, the two first adsorption surfaces are arranged opposite to each other in the first direction.

[0077] Then, when changing the roll and splicing the tape, the glue sticking platform 330 will move along the second direction to between the two splicing platforms 220, and then the two splicing platforms 220 will move closer together, so that the material tapes 110 on the two first adsorption surfaces are simultaneously bonded to the adhesive tape on the second adsorption surface.

[0078] It is understandable that arc transition design can be adopted for the edges and corners of the tape splicing platform 220 and the edges and corners of the glue laminating platform 330 .

[0079] The output end of the second linear drive member 310 is connected to the glue sticking platform 330, and the second linear drive member 310 can provide a driving function for the glue sticking platform 330. When the second linear drive member 310 is working, the output end of the second linear drive member 310 can drive the glue sticking platform 330 to move along the second direction. It can be understood that the second linear drive member 310 can be a linear drive device such as an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, a linear module, etc., which can drive the glue sticking platform 330 to move linearly.

[0080] In this embodiment, the second linear drive member 310 is a telescopic cylinder, which is arranged on the mounting seat 700, and the movable rod of the telescopic cylinder is fixedly connected to the glue sticking platform 330. The glue sticking platform 330 can be installed on the mounting seat 700 through the slide rail slider pair 800, and when the telescopic cylinder is running, the glue sticking platform 330 can move quickly and smoothly in the left and right directions.

[0081] In some embodiments, Figures 1 to 4 As shown, the structure of the tape cutting assembly 400 includes a cutter 420 and a third linear drive member 410 .

[0082] The function of the cutter 420 is to cut off the old material strip on the first adsorption surface. In this embodiment, the length direction of the cutter 420 extends in the up-down direction, and the old material strip can be cross-cut. Of course, it is not excluded that the cutter 420 cuts the old material strip obliquely.

[0083] The third linear drive member 410 is disposed on the glue laminating platform 330. Under the driving action of the second linear drive member 310, the third linear drive member 410 can move along the second direction with the glue laminating platform 330. The output end of the third linear drive member 410 is connected to the cutter 420, and the third linear drive member 410 can drive the cutter 420 to move along the second direction. It can be understood that the third linear drive member 410 can be a linear drive device such as a cylinder, a hydraulic cylinder, or an electric cylinder.

[0084] In this embodiment, the third linear drive member 410 is a thin cylinder, which has the advantages of compact structure, light weight and small space occupation. The glue sticking platform 330 is provided with a mounting portion, which provides a mounting position for the two tape cutting assemblies 400, and there is no need to add an additional bulky support to install the tape cutting assembly 400. Moreover, the driving stroke of the second linear drive member 310 can be effectively utilized, so that the glue sticking platform 330 and the tape cutting assembly 400 can free up enough space, which is convenient for the staff to place the adhesive tape on the second adsorption surface.

[0085] In order to improve the movement stability of the cutter 420 , the cutter 420 or the connection between the cutter 420 and the third linear drive member 410 can be slidably connected to the glue laminating platform 330 in the second direction.

[0086] In some embodiments, Figure 3 and Figure 4 As shown, the glue sticking platform 330 is provided with a receiving hole 331, and the receiving hole 331 respectively penetrates two side surfaces of the glue sticking platform 330 in the second direction. There are two receiving holes 331, which are respectively arranged on opposite sides of the second adsorption surface in the first direction and are respectively arranged corresponding to the two cutters 420. The shape and size of the receiving hole 331 can allow the cutter 420 to enter and exit.

[0087] The cutter 420 is arranged to extend along the third direction, so the storage hole 331 is a long hole and extends along the third direction. The cutter 420 is configured to be able to enter and exit the storage hole 331 along the second direction under the driving action of the third linear drive member 410. It can be understood that when there is no need for tape cutting operation, the cutter 420 enters the storage hole 331 under the action of the third linear drive member 410 to store and hide the cutter 420 in the storage hole 331, thereby avoiding the cutter 420 from causing harm to the staff and improving the safety of the automatic roll changing mechanism. After the adhesive tape is bonded to the new tape and the old tape, the cutter 420 extends out of the storage hole 331 under the driving action of the third linear drive member 410 and cuts the adhesive tape.

[0088] In this embodiment, the glue sticking platform 330 includes a support block and a glue sticking block. The glue sticking block is provided with a second adsorption surface. The glue sticking block is detachably arranged in the installation groove provided in the support block. The receiving hole 331 is provided on the support block.

[0089] In some embodiments, Figure 3 As shown, the adhesive laminating platform 330 is provided with a scale 370, the length direction of the scale 370 extends along the third direction, and the scale 370 is provided on either side of the second adsorption surface in the first direction. The size of the second adsorption surface in the third direction is larger than the size of the adhesive tape.

[0090] It can be understood that the scale 370 includes a central scale line and two scale areas, and the two scale areas are symmetrically arranged about the central scale line in the third direction. The scale values ​​of the scale areas can gradually increase or decrease from the central scale line. In this embodiment, the scale value corresponding to the central scale line is 0, and the scale area increases from the central scale line to the end of the scale 370. The maximum value of the scale area can be set according to actual conditions such as the width of the material strip, for example, the maximum scale value is 10 cm.

[0091] When the staff puts the adhesive tape on the second adsorption surface, the adhesive tape can be positioned by the scale 370. For example, if the width dimension of the material strip 110 is D and the width dimension of the adhesive tape is D, then the upper and lower ends of the adhesive tape are aligned at the D / 2 position of the scale 370 to complete the positioning of the adhesive tape on the second adsorption surface. Therefore, when applying the adhesive tape, it can be ensured that the adhesive tape can be aligned with the new material strip and the old material strip in the width direction, and a good bonding effect can be achieved.

[0092] In some embodiments, Figures 1 to 4 As shown, the structure of the glue sticking assembly 300 also includes a slide seat 320 and a rotation driving component.

[0093] The slide 320 can be mounted on the mounting seat 700 through the slide rail and slider pair 800, so that the slide 320 can move along the second direction relative to the mounting seat 700. The second linear drive member 310 is disposed on the mounting seat 700, and the output end of the second linear drive member 310 is fixedly connected to the slide 320 to provide a driving function for the slide 320, so that the slide 320 moves along the second direction under the driving function of the second linear drive member 310 to approach or move away from the belt splicing assembly 200.

[0094] The glue sticking platform 330 is rotatably connected to the slide 320 via a rotating shaft, and the glue sticking platform 330 is fixedly connected to the rotating shaft, and the rotating shaft extends along the third direction. The rotation drive component is arranged on the slide 320 and can move linearly with the slide 320. The output end of the rotation drive component is connected to the glue sticking platform 330, and under the driving action of the rotation drive component, the glue sticking platform 330 can rotate around the axis along the third direction.

[0095] It is understandable that the rotary drive component can be a rotary cylinder, or can include a motor and a slewing bearing, wherein the slewing bearing is disposed between the glue sticking platform 330 and the slide seat 320, and the output shaft of the motor is provided with a driving wheel, and the motor can drive the slewing bearing to drive the glue sticking platform 330 to rotate through the driving wheel. By means of the rotary drive component, the glue sticking platform 330 can be controlled to rotate to a certain angle so that the staff can place the adhesive tape on the second adsorption surface.

[0096] For example, Figure 1 and Figure 2As shown, the staff can rotate the glue sticking platform 330 by rotating the driving component until the second adsorption surface faces away from the tape splicing assembly 200. Then, the staff standing beside the automatic roll-changing mechanism can quickly and accurately stick the adhesive tape on the second adsorption surface to avoid the adhesive tape feeding work being hindered by other components of the automatic roll-changing mechanism. Then, the rotating driving component is used to drive the glue sticking platform 330 to rotate 180° so that the adhesive tape on the second adsorption surface faces the tape splicing assembly 200, so that under the driving action of the second linear driving member 310, the glue sticking platform 330 directly presses the adhesive tape on the new material tape and the old material tape.

[0097] In addition, when the tape cutting assembly 400 is disposed on the glue laminating platform 330 , a rotary driving component can be used to drive the glue laminating platform 330 and the tape cutting assembly 400 to rotate to a certain angle, so that the staff can perform maintenance on the tape cutting assembly 400 .

[0098] In a preferred embodiment, the rotation driving component includes a gear 360, a rack 340 and a fourth linear driving member 350. The gear 360 is fixedly connected to the glue laminating platform 330. Specifically, the gear 360 can be set on the rotating shaft of the glue laminating platform 330 so that the gear 360 can rotate with the glue laminating platform 330. The rack 340 is meshed with the gear 360, and the rack 340 can be installed on the slide seat 320 through the slide rail and slider pair 800.

[0099] The fourth linear drive member 350 is disposed on the slide 320 and can move linearly with the slide 320. The output end of the fourth linear drive member 350 is connected to the rack 340 to drive the rack 340 to move linearly and drive the gear 360 to rotate. It can be understood that the fourth linear drive member 350 can be a cylinder, an electric cylinder, etc.

[0100] In this embodiment, the fourth linear drive member 350 is a telescopic cylinder. In order to facilitate the disassembly and assembly of the rack 340 and the fourth linear drive member 350, the rack 340 and the fourth linear drive member 350 are arranged on the right side of the slide 320, and the length direction of the rack 340 and the telescopic direction of the fourth linear drive member 350 are both extended in the front-to-back direction. The rotary drive component of this embodiment adopts the above-mentioned structural arrangement, which is convenient for maintenance, low in operating cost, and occupies little space in the third direction.

[0101] In some embodiments, Figure 1 and Figure 2 As shown, the automatic roll changing mechanism further includes a material pulling assembly 500. The structure of the material pulling assembly 500 includes a roller 520 and a fifth linear driving member 510.

[0102] The center axis of the roller 520 extends along the third direction. Two rollers 520 are provided. The two rollers 520 are arranged at a certain interval along the first direction. Moreover, a material transfer channel is formed between the two rollers 520, and the material transfer channel can allow the feeding belt 110 to pass through.

[0103] The fifth linear drive member 510 is configured to drive the two rollers 520 away from the glue application assembly 300 along the second direction, so as to close the two tape splicing assemblies 200. It is understandable that a fifth linear drive member 510 can be used for each roller 520 to drive the roller 520 to move linearly, or the same fifth linear drive member 510 can be used to drive the two rollers 520 to move linearly at the same time. The fifth linear drive member 510 can be a linear drive device such as a cylinder or an electric cylinder.

[0104] In this embodiment, the fifth linear drive member 510 is a telescopic cylinder, and is fixedly connected to the mounting seat 700. The movable rod of the telescopic cylinder is connected to the translation seat 530, and the translation seat 530 can be installed on the mounting seat 700 through the slide rail slider pair 800. Two rollers 520 are arranged on the translation seat 530.

[0105] It is understandable that when the two belt connection platforms 220 are in a separated state, the size of the material belt channel in the first direction is the largest, and the translation seat 530 can drive the two rollers 520 to move into the material belt channel along the second direction. At this time, the material belt 110 is in the conveying stage, and the material belt 110 will bypass one of the rollers 520 and move along the material channel. For example, when the rear belt connection platform 220 vacuum absorbs a new material belt, the old material belt will move backwards and move to the left to the next station after bypassing the front roller 520. The roller 520 can give the material belt 110 good tension and prevent the material belt 110 from being severely worn due to excessive contact with the belt connection platform 220 during the conveying process.

[0106] When it is necessary to change the roll and splice the tape, the fifth linear drive 510 drives the two rollers 520 to move to the left, so that the translation seat 530 and the rollers 520 leave the tape channel, so that the two tape splicing platforms 220 can be closed. After the roll change and splicing are completed, the two tape splicing platforms 220 are separated, and then the two rollers 520 enter the tape channel under the driving action of the fifth linear drive 510, and apply tension to the tape 110 that has completed the splicing process, and let the tape 110 leave the tape splicing platform 220 to prevent the tape 110 from being worn by the tape splicing platform 220.

[0107] The various parts of the automatic roll changing mechanism in the above embodiment are driven and controlled independently, and the control steps are simple.

[0108] In addition, if Figures 1 to 4As shown, the second embodiment of the utility model provides a stacking machine, which can automatically stack battery cells and is an important equipment for automated battery production.

[0109] The structure of the stacking machine includes an unwinding mechanism and the automatic roll changing mechanism of the above embodiment. There are two unwinding mechanisms, and the two unwinding mechanisms are respectively arranged corresponding to the two tape connection assemblies 200. In this embodiment, the two unwinding mechanisms are respectively located at the front side and the rear side of the pulling assembly 500.

[0110] It is understandable that the unwinding mechanism includes an unwinding shaft 600, which extends along the third direction. The staff can place the material roll 100 on the unwinding shaft 600. When the unwinding mechanism is working, the material roll 100 will rotate and unwind the material belt 110, so that the membrane can be unwound. In order to increase the tension of the material belt 110, a tension roller can be provided to apply tension to the material belt 110 located between the material roll 100 and the over roller 520. In addition, other tension rollers can be provided to apply tension to the material belt 110 transported from the over-feed channel to the next station.

[0111] The preferred implementation methods of the utility model are described in detail above, but the invention of the utility model is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the utility model. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
