Description

Technical Field

[0001] This invention belongs to the field of battery cell manufacturing technology, specifically providing a tape changing device and a tape changing method. Background Technology

[0002] Lithium batteries are devices that store electrical charge and are widely used in various electrical appliances.

[0003] In the production process of lithium battery cells, the fully automated winding process includes the unwinding of electrode strips and film strips. However, the existing unwinding mechanism generally uses single strip unwinding. After a single strip is used up, the machine needs to be stopped to replace it with a new strip. Stopping the machine to replace the strip will affect the production efficiency of the battery cells.

[0004] To improve production efficiency, existing technologies have developed automatic tape splicing devices with dual rolls. After one roll is used up, the head of the other roll is attached to the tail of the working roll using tape to achieve splicing, thus shortening tape changeover time. However, existing automatic tape splicing devices require manual picking of the spare roll head and moving it to the splicing position during tape changeover, which also necessitates a brief machine stop. This cannot meet the demand for uninterrupted production and results in low production efficiency.

[0005] Accordingly, a new technical solution is needed in this field to solve the above-mentioned technical problems. Summary of the Invention

The tape preparation device is configured to acquire tape of a preset length and to prepare tape of the preset length to the first picking device, the first applying device, and the second applying device, so as to form the first tape, the second tape, and the third tape, respectively.

[0025] In the preferred embodiment of the tape changing device described above, the adhesive preparation device includes a tape output mechanism, a third sliding mechanism, and a tape feeding mechanism; the tape output mechanism is mounted on the fixed device and is used to output tape; the third sliding mechanism is mounted on the fixed device and is configured to drive the tape feeding mechanism to move; the tape feeding mechanism is mounted on the third sliding mechanism and is configured to acquire tape of a preset length and to transport the tape of the preset length to the first pickup device, the first adhesive applicator, and the second adhesive applicator.

[0026] In the preferred embodiment of the tape changing equipment described above, the tape feeding mechanism includes a third cylinder, a rotary cylinder, a transfer block, and a tape cutting component.

[0027] In the preferred embodiment of the belt changing device described above, the belt changing device further includes a third driving member, the second adhesive applicator is pivotally mounted on the pressing device, the third driving member is connected to the second adhesive applicator and can drive the second adhesive applicator to rotate around a vertical pivot axis.

[0028] Secondly, the present invention provides a belt changing method similar to the belt changing device described above, the belt changing method comprising: S100: the sliding device moves the first pickup device, which adsorbs the first adhesive tape, to the spare material belt; S200: the first pickup device adheres one end of the adsorbed first adhesive tape to one side of the starting end of the spare material belt; S300: the sliding device drives the first pickup device, which adsorbs the first adhesive tape and the spare material belt, to move; S400: the pressing device pushes the working material belt to move and docks with the first pickup device to adhere one side of the working material belt to the other end of the first adhesive tape; S500: the cutting device cuts the working material belt; or, the belt changing method comprises S100: The sliding device moves the first pickup device, which has adsorbed the first tape, to the spare material strip; S200: The first pickup device attaches one end of the adsorbed first tape to one side of the starting end of the spare material strip; S300: The sliding device drives the first pickup device, which has adsorbed the first tape and the spare material strip, to move so that the first pickup device aligns with the first adhesive applicator, thereby attaching the other end of the first tape to one end of the second tape; S400: The pressing device pushes the working material strip to move and aligns with the first adhesive applicator to attach one side of the working material strip to the other end of the second tape; S500: The cutting device cuts the working material strip.

[0029] In the preferred embodiment of the above belt changing method, when the belt changing equipment includes the second adhesive applicator, the belt changing method further includes the following step: S600: The second adhesive applicator applies the third adhesive tape to the other side of the working belt and the spare belt.

[0030] By adopting the above technical solution, the present invention automatically picks up the material head by setting up a first picking device, thereby picking up the material head of the spare material strip in advance and moving the spare material strip to the splicing position to wait for splicing, eliminating the need for manual picking of the material head and saving time in preparing the spare material strip; in addition, during the splicing operation, the pressing device operates, pushing the working material strip to move so that the working material strip is pasted with the first tape or the second tape, and then the cutting device cuts the working material strip. The splicing time is short and the speed is fast, which can realize automatic splicing operation without stopping the machine and improve work efficiency.

[0031] Furthermore, by setting up a second adhesive applicator, which can adsorb the third adhesive tape and stick it to the other side of the spare material belt and the working material belt, this setup can achieve double-sided adhesive application in a very short time, improve the adhesion of the material belt, and thus reduce the probability of belt breakage during conveying.

[0032] Furthermore, installing the second adhesive applicator on the pressing device facilitates assembly and use.

[0033] Furthermore, the first adhesive application device is configured as a first cylinder and a pressing block. The first cylinder can push the pressing block to move, thereby pushing the working material strip towards the other end of the first adhesive strip or the other end of the second adhesive strip, thus completing the bonding operation between one side of the working material strip and one side of the spare material strip. This configuration is simple in structure, small in size, and easy to assemble and use.

[0034] Furthermore, by setting a first rotating mechanism, the first cylinder can be rotated 180 degrees, which can change the facing direction of the pressing block, so as to realize bidirectional belt connection, that is, the left belt can be connected to the right belt, or the right belt can be connected to the left belt.

[0035] Furthermore, the first adhesive applicator includes a first adhesive block, which has a first cavity inside. The first cavity is connected to a vacuum device so that a vacuum suction force is formed inside the first cavity to adsorb and fix the second adhesive tape. The structure is simple and has strong adsorption force.

[0036] Furthermore, by setting a second rotating mechanism, the first adhesive block can be driven to rotate, thereby changing the mating direction of the first adhesive block, so that it can be used for bidirectional tape splicing, that is, left tape to right tape or right tape to left tape.

[0037] Furthermore, the first pickup device is configured as a first connector, a first shaft, a pickup component, and a first drive component. The pickup component can adsorb the first tape, thereby smoothly picking up the head of the spare tape. The first drive component can drive the pickup component to rotate, thereby driving the spare tape to unwind. This configuration is simple in structure, compact in layout, small in size, and easy to control.

[0038] Furthermore, a horizontal section and an inclined section are provided on the side wall of the pickup part away from the first axis. With this arrangement, when the horizontal section comes into contact with the spare material strip, the first tape adsorbed on the horizontal section adheres to the material head of the spare material strip, while the first tape adsorbed on the inclined section does not adhere to the spare material strip, thereby enabling the material head to be picked up smoothly and unwound.

[0039] Furthermore, the pickup component is also provided with an arc-shaped surface. During the rotation of the pickup component, its arc-shaped surface contacts the spare material roll, thereby preventing the sharp end of the pickup component from rubbing against the spare material roll and protecting the spare material roll from damage.

[0040] Furthermore, the third rotating mechanism can drive the first connector to rotate 180 degrees. This configuration can change the picking position of the pickup, allowing it to pick up the head of the spare tape unwound clockwise or counterclockwise. This enables bidirectional tape splicing in conjunction with the pressing device and the first adhesive applicator, thus broadening its applicability.

[0041] Furthermore, a clamping mechanism is provided to clamp the first tape adsorbed on the inclined part. This arrangement can fix the first tape, so that when the first pickup device drives the roll to rotate and unwind, the adsorbed first tape will not slip off, thus improving the adsorption stability.

[0042] Furthermore, the clamping mechanism is configured as a hook, a second shaft, and a second drive. The second drive can drive the hook to rotate along the second shaft, so that the other end of the hook abuts against the inclined part, thereby clamping the first tape. This configuration is simple in structure, easy to control and use, and easy to assemble.

[0043] Furthermore, a clamping roller is provided at the other end of the hook and claw component, and an anti-stick coating is provided on the roller surface of the clamping roller. This arrangement prevents the roller surface of the clamping roller from sticking to the first tape, so that the clamping roller and the first tape can be separated at any time, thus facilitating use.

[0044] Furthermore, the sliding device is configured as a first sliding mechanism and a second sliding mechanism. The first sliding mechanism and the second sliding mechanism respectively drive the first picking device and the second picking device to move in the vertical and horizontal directions, so that the sliding device can drive the first picking device and the second picking device to move in the vertical plane, which facilitates the control of the movement path.

[0045] Furthermore, by setting up a glue preparation device, automatic glue preparation can be achieved, saving labor and improving production efficiency.

[0046] Furthermore, the belt changing method of the present invention automatically picks up the material head by setting up a first picking device, which saves the time of manual picking up of the material head. After the working material belt is pasted with the first adhesive tape, the cutting device can cut the working material belt in time. The time required for pasting the material belt is short, which can be completed within 1-2 seconds, thereby realizing non-stop operation and effectively improving work efficiency.

[0047] Furthermore, a second adhesive applicator is provided. After the working strip is cut, a third adhesive tape is applied to the other side of the working strip and the spare strip to achieve double-sided adhesive application, which improves the firmness of the joint position. Moreover, the adhesive application action is quick and can also be performed without stopping the machine.

[0109] Example 1

[0110] Specifically, such as Figure 1 As shown, the tape changing device of the present invention includes a fixing device 1, a sliding device 2, a first pickup device 3, a pressing device 4, and a cutting device 5. The fixing device 1 is used to install the sliding device 2, the first pickup device 3, the pressing device 4, and the cutting device 5. In practical applications, the fixing device 1 is preferably configured as a fixed frame with a fixing plate. The fixing device 1 is also equipped with a working material roll 6 and a spare material roll 7. The working material roll 6 is used to unwind the working material tape 11, and the spare material roll 7 is used to unwind the spare material tape 12.

[0111] The sliding device 2 is mounted on the fixed device 1, and the first picking device 3 is mounted on the sliding device 2. The sliding device 2 is configured to drive the first picking device 3 to move, thereby driving the first picking device 3 to the material preparation position and the tape receiving position. The first picking device 3 is configured to adsorb the first tape (not shown in the figure), and to stick one end of the adsorbed first tape to one side of the starting end of the spare material tape 12 at the material preparation position, so that the first picking device 3 can adsorb the starting end of the spare material tape 12.

[0112] The pressing device 4 is configured to push the working material strip 11 to move and dock with the first picking device 3 to stick one side of the working material strip 11 to the other end of the first adhesive tape; the cutting device 5 is configured to cut the working material strip 11 after it is stuck to the first adhesive tape.

[0113] In the tape-changing device of the present invention, during tape splicing, the first pickup device 3 can pre-adsorb the first tape, and then move to the preparation position under the drive of the sliding device 2 (see reference). Figure 4 The first tape is then attached and fixed to the end of the spare material tape 12 unwound from the spare material roll 7; subsequently, driven by the sliding device 2, the first tape and the spare material tape 12 are moved to the tape receiving position (see reference). Figure 5 When the working material strip 11 on the working material roll 6 is about to be unwound, the pressing device 4 operates, pushing the working material strip 11 toward the first picking device 3 located at the tape splicing position, and sticking the working material strip 11 onto the first adhesive tape, thereby achieving the bonding and splicing of the working material strip 11 and the spare material strip 12 on one side. After the working material strip 11 and the first adhesive tape are bonded, the cutting device 5 operates to cut the working material strip 11, so that the spare material strip 12 becomes a new working material strip 11 for continued use.

[0114] The belt-changing device of the present invention, by setting a first picking device 3, can automatically pick up the head of the spare material belt 12 in advance and move it to the belt-connecting position for standby, eliminating the need for manual picking of the head and saving time in preparing the spare material belt 12. When performing the belt-connecting operation, it is only necessary to operate the pressing device 4 to push the working material belt 11 to move and stick the working material belt 11 to the first adhesive tape, and then the cutting device 5 to cut the working material belt 11. The overall belt-connecting time is short and fast, and automatic belt-connecting can be achieved without stopping the machine, thus improving work efficiency.

[0115] Preferably, such as Figure 1 As shown, the belt changing device of the present invention further includes a second adhesive applicator 8, which is configured to adsorb a third adhesive tape (not shown in the figure) and to stick the third adhesive tape to the other side of the spare material belt 12 and the working material belt 11.

[0116] The second adhesive applicator 8 is located on one side of the tape receiving position. During operation, the second adhesive applicator 8 moves with the third tape and docks with the first pickup device 3, thereby sticking the third tape to the other side of the spare material tape 12 and the working material tape 11, thus achieving double-sided adhesive application of the spare material tape 12 and the working material tape 11 and improving adhesive stability.

[0117] Preferably, such as Figure 6 As shown, the second adhesive applicator 8 is mounted on the pressing device 4.

[0118] The second adhesive applicator 8 is installed on the pressing device 4 to facilitate assembly and use.

[0119] Example 2

[0120] Specifically, such as Figure 2 As shown, the tape changing device of the present invention includes a fixing device 1, a sliding device 2, a first pickup device 3, a pressing device 4, a cutting device 5, and a first adhesive applicator 14. The fixing device 1 is used to install the sliding device 2, the first pickup device 3, the pressing device 4, the cutting device 5, and the first adhesive applicator 14. In practical applications, the fixing device 1 is preferably configured as a fixed frame with a fixing plate. The fixing device 1 is also equipped with a working material roll 6 and a spare material roll 7. The working material roll 6 is used to unwind the working material tape 11, and the spare material roll 7 is used to unwind the spare material tape 12.

[0121] The sliding device 2 is mounted on the fixed device 1, and the first picking device 3 is mounted on the sliding device 2. The sliding device 2 is configured to drive the first picking device 3 to move, thereby driving the first picking device 3 to the material preparation position and the tape receiving position. The first picking device 3 is configured to adsorb the first tape (not shown in the figure), and to stick one end of the adsorbed first tape to one side of the starting end of the spare material tape 12 at the material preparation position, so that the first picking device 3 can adsorb the starting end of the spare material tape 12.

[0122] The first adhesive applicator 14 is configured to adsorb the second adhesive tape (not shown in the figure) and to dock with the first pickup device 3, which adsorbs the first adhesive tape and the spare tape 12, so that the other end of the first adhesive tape is pasted to one end of the second adhesive tape.

[0123] The pressing device 4 is configured to push the working material strip 11 to move and dock with the first adhesive applicator 14 to stick one side of the working material strip 11 to the other end of the second adhesive strip; the cutting device 5 is configured to cut the working material strip 11 after it is stuck to the second adhesive strip.

[0124] In the belt changing device of the present invention, when exchanging belts, the first pickup device 3 pre-adsorbs the first tape, and then moves to the preparation position under the drive of the sliding device 2 (see reference). Figure 4 The first tape is attached to the end of the spare tape 12 unwound from the spare tape roll 7. Then, driven by the sliding device 2, the first tape and the spare tape 12 are moved and connected to the first adhesive device 14 located at the tape connection position, and the other end of the first tape is attached to one end of the second tape. When the working tape 11 on the working tape roll 6 is about to be unwound, the pressing device 4 operates, pushing the working tape 11 toward the first adhesive device 14 located at the tape connection position, and attaching the working tape 11 to the other end of the second tape, thereby achieving the connection of the working tape 11 and one side of the spare tape 12. After the working tape 11 and the second tape are attached, the cutting device 5 operates to cut the working tape 11, so that the spare tape 12 becomes a new working tape 11 for continued use.

[0125] The belt-changing device of the present invention automatically picks up the head of the spare material belt 12 in advance by setting the first picking device 3, and after docking with the first adhesive applicator 14, the spare material belt 12 is pasted on the second adhesive tape and placed in the belt-connecting position for later use. There is no need for manual picking of the head, saving the time of preparing the spare material belt 12. When performing the belt-connecting operation, it is only necessary to run the pressing device 4 to push the working material belt 11 to move and paste it with the second adhesive tape, and then the cutting device 5 cuts the working material belt 11. The overall belt-connecting time is short and fast, and automatic belt-connecting can be achieved without stopping the machine, thus improving work efficiency.

[0126] Preferably, such as Figure 2 As shown, the belt changing device of the present invention further includes a second adhesive applicator 8, which is configured to adsorb a third adhesive tape (not shown in the figure) and to stick the third adhesive tape to the other side of the spare material belt 12 and the working material belt 11.

[0127] The second adhesive applicator 8 is located on one side of the tape receiving position. During operation, it moves with the third tape and docks with the first adhesive applicator 14, thereby sticking the third tape to the other side of the spare material tape 12 and the working material tape 11, realizing double-sided adhesive application of the spare material tape 12 and the working material tape 11, and improving the adhesive stability.

[0128] Preferably, such as Figure 6 As shown, the second adhesive applicator 8 is mounted on the pressing device 4.

[0129] The second adhesive applicator 8 is installed on the pressing device 4 to facilitate assembly and use.

[0130] It should be noted that the material preparation position in Embodiments 1 and 2 of the present invention is the position where the first picking device 3 picks up the head of the spare material strip 12, and its specific position is set according to the setting position of the spare material roll 7. The tape joining position in Embodiment 1 of the present invention is the position where the first picking device 3 cooperates with the pressing device 4 to bond the working material strip 11 and the spare material strip 12, and its specific position is set according to the position of the pressing device 4 and the travel path of the working material strip 11. The tape joining position in Embodiment 2 of the present invention is the position where the pressing device 4 cooperates with the first adhesive applicator 14 to bond the working material strip 11 and the spare material strip 12, and its specific position is set according to the position of the pressing device 4 and the travel path of the working material strip 11.

[0131] It should be noted that this invention does not impose any limitations on the specific structure of the pressing device 4, as long as the pressing device 4 can push the working material strip 11 to move, thereby bonding the working material strip 11 to the first adhesive tape or the second adhesive tape. In practical applications, those skilled in the art can customize the specific structure of the pressing device 4 according to actual needs. For example, the pressing device 4 can be configured as a cylinder and a pressing block, or it can be configured as an electric push rod and a pressing block, or it can be configured as a sliding mechanism + pressing block structure, and so on. Such adjustments and changes to the specific structure of the pressing device 4 do not deviate from the basic principles of this invention and should all be limited to the protection scope of this invention.

[0132] Preferably, such as Figure 1 , Figure 2 and Figure 6 As shown, the pressing device 4 includes a first cylinder 41 and a pressing block 42. The first cylinder 41 is mounted on the fixing device 1, the pressing block 42 is mounted on the end of the piston rod of the first cylinder 41 and is positioned towards the tape receiving position, and the cutting device 5 is mounted on the pressing block 42.

[0133] The pressing device 4 is configured as a first cylinder 41 and a pressing block 42. When performing the tape splicing operation, the first cylinder 41 pushes the pressing block 42 toward the tape splicing position, so that the pressing block 42 docks with the first pickup device 3 or the first adhesive applicator 14, and pastes one side of the working material tape 11 onto the other end of the first tape or the other end of the second tape. The structure is simple, the operation is convenient, and the response speed is fast.

[0134] Preferably, such as Figure 6 As shown, the pressing device 4 also includes a first rotating mechanism 43, which is disposed between the fixing device 1 and the first cylinder 41. The first rotating mechanism 43 is configured to drive the first cylinder 41 to rotate around a vertical axis.

[0135] By setting the first rotating mechanism 43, the first cylinder 41 can be rotated around the vertical axis, that is, the first cylinder 41 can be rotated horizontally, thereby changing the facing direction of the pressing block 42, so that the pressing device 4 can be applied to the situation of left belt to right belt and right belt to left belt, thus improving the application range.

[0136] Preferably, such as Figure 6 As shown, the first rotating mechanism 43 includes a first assembly 431, a second assembly 432, a third assembly 433, a fourth driving member (not shown in the figure), a fifth driving member (not shown in the figure), and a sixth driving member (not shown in the figure).

[0137] The first cylinder 41 is pivotally connected to one end of the first assembly 431 via a first vertical pivot axis. The fourth drive member is connected to the first cylinder 41 and can drive the first cylinder 41 to rotate around the first vertical pivot axis. One end of the second assembly 432 is pivotally connected to the other end of the first assembly 431 via a second vertical pivot axis. The fifth drive member is connected to the other end of the first assembly 431 and can drive the first assembly 431 to rotate around the second vertical pivot axis. The third assembly 433 is fixedly installed on the fixing device 1. The other end of the second assembly 432 is pivotally connected to the third assembly 433 via a third vertical pivot axis. The sixth drive member is connected to the other end of the second assembly 432 and can drive the second assembly 432 to rotate around the third vertical pivot axis.

[0138] The first rotating mechanism 43 is configured as a first assembly 431, a second assembly 432, a third assembly 433, a fourth drive component, a fifth drive component, and a sixth drive component. Its structure is simple, easy to assemble and use, and easy to control.

[0139] It should be noted that the present invention does not impose any restrictions on the specific structure of the first adhesive applicator 14. As long as the first adhesive applicator 14 can adsorb the second adhesive tape and can dock with the first pickup device 3, so that the first adhesive tape with the spare material tape 12 is attached to the second adhesive tape, in practical applications, those skilled in the art can set the specific structure of the first adhesive applicator 14 according to actual needs.

[0140] As a preferred implementation method, such as Figure 7 As shown, the first adhesive applicator 14 includes a first adhesive block 141 mounted on the fixing device 1. The first adhesive block 141 has a first cavity (not shown in the figure) inside. The first adhesive block 141 has a first through hole communicating with the first cavity. The first cavity is connected to a vacuum device so that a vacuum suction force is formed inside the first cavity under the action of the vacuum device, thereby adsorbing the second tape onto the first adhesive block 141.

[0141] Preferably, such as Figure 7As shown, the first adhesive applicator 14 also includes a second rotating mechanism 142, which is disposed between the fixing device 1 and the first adhesive block 141. The second rotating mechanism 142 is configured to drive the first adhesive block 141 to rotate around a vertical axis, that is, to enable the first adhesive block 141 to rotate horizontally.

[0142] By setting the second rotating mechanism 142, the first adhesive block 141 can be driven to rotate, which can change the bonding direction of the second adhesive tape adsorbed by the first adhesive block 141. This allows the first adhesive device 14 to perform bonding operations in different left and right directions, making it convenient to use and expanding its application range.

[0143] It should be noted that the present invention does not impose any restrictions on the specific structure of the second rotating mechanism 142, as long as the second rotating mechanism 142 can drive the first adhesive block 141 to rotate, thereby changing the docking direction of the first adhesive block 141. In practical applications, those skilled in the art can set the specific structure of the second rotating mechanism 141 according to actual needs. Preferably, the second rotating mechanism 142 is set to the same structure as the first rotating mechanism 44.

[0144] In another preferred embodiment, the first adhesive applicator 14 includes a second pickup device. The structure of the second pickup device is the same as that of the first pickup device 3. The second pickup device is mounted on the sliding device 2. The sliding device 2 is also configured to drive the second pickup device to move. The second pickup device is configured to absorb the second adhesive tape and to dock with the first pickup device 3 so that the other end of the first adhesive tape is pasted with one end of the second adhesive tape.

[0145] The first adhesive applicator 14 is configured as a second pickup device with the same structure as the first pickup device 3. The structure is simple and easy to assemble and use. In addition, in practical applications, the second pickup device is used in conjunction with the first pickup device 3 to realize the pickup operation of spare material heads in different directions, which is more convenient for application.

[0146] It should also be noted that the present invention does not impose any restrictions on the specific structure of the sliding device 2, as long as the sliding device 2 can drive the first picking device 3 and the second picking device to move. In practical applications, those skilled in the art can set the specific structure of the sliding device 2 according to actual needs. For example, the sliding device 2 can be set as a combination of a vertical sliding mechanism and a horizontal sliding mechanism, or it can be set as a sliding mechanism with a circular path, and so on. Such adjustments and changes to the specific structure of the sliding device 2 do not deviate from the basic principles of the present invention and should all be limited to the protection scope of the present invention.

[0147] Preferably, such as Figure 1 and Figure 2As shown, the sliding device 2 includes a first sliding mechanism 21 and a second sliding mechanism 22 mounted on the fixed device 1. The second sliding mechanism 22 is mounted on the first sliding mechanism 21. The first picking device 3 and the second picking device are both mounted on the second sliding mechanism 22. The first sliding mechanism 21 is configured to drive the second sliding mechanism 22, the first picking device 3 and the second picking device to move vertically relative to the fixed device 1. The second sliding mechanism 22 is configured to drive the first picking device 3 and the second picking device to move horizontally relative to the fixed device 1.

[0148] The sliding device 2 is configured as a first sliding mechanism 21 and a second sliding mechanism 22, wherein the second sliding mechanism 22 is mounted on the first sliding mechanism 21. The first sliding mechanism 21 and the second sliding mechanism 22 cooperate to drive the first picking device 3 and the second picking device to the required position; the structure is simple, easy to assemble and use and easy to control.

[0149] It should be noted that the present invention does not impose any restrictions on the specific structure of the first sliding mechanism 21 and the second sliding mechanism 22, as long as the first sliding mechanism 21 and the second sliding mechanism 22 can drive the connected device to move. In practical applications, those skilled in the art can set the specific structure of the first sliding mechanism 21 and the second sliding mechanism 22 according to actual needs. For example, the first sliding mechanism 21 and the second sliding mechanism 22 can be set as a linear sliding module, or they can be set as a structure in which a driving member drives a gear to rotate and thus drives a rack to move, or they can be set as a structure in which a ball screw and a slider cooperate, and so on. Such adjustments and changes to the specific structure of the first sliding mechanism 21 and the second sliding mechanism 22 do not deviate from the basic principles of the present invention and should all be limited to the protection scope of the present invention.

[0150] It should also be noted that the present invention does not impose any restrictions on the specific structure of the first pickup device 3, as long as the first pickup device 3 can smoothly pick up the material head of the spare material roll 7 at the material preparation position and unwind it. In practical applications, those skilled in the art can set the specific structure of the first pickup device 3 according to actual needs. Adjustments and changes to the specific structure of the first pickup device 3 do not deviate from the basic principles of the present invention and should all be limited to the protection scope of the present invention.

[0151] Preferably, such as Figure 1 , Figure 8 , Figure 9 and Figure 10 As shown, the first pickup device 3 includes a first connector 31, a pickup member 33, a first shaft (not shown in the figure), and a first drive member (not shown in the figure).

[0152] The first connector 31 is mounted on the sliding device. The pickup 33 is pivotally connected to the first connector 31 via a first shaft, and the pickup 33 is located below the first connector 31. The first drive is connected to the pickup 33 and can drive the pickup 33 to rotate around the first shaft. The pickup 33 has a second cavity 331 inside. The side wall of the pickup 33 away from the first shaft has a plurality of second through holes 332 communicating with the second cavity 331. The first cavity 331 is connected to a vacuum device so that a vacuum suction force is formed inside the second cavity 331 under the action of the vacuum device, thereby adsorbing the first tape onto the side wall of the pickup 33.

[0153] The first pickup device 3 is configured as a first connector 31, a first shaft, a pickup 33, and a first drive. The pickup 33 has a second cavity 331 inside, and a plurality of second through holes 332 communicating with the second cavity 331 are provided on the side wall of the pickup 33, so that a vacuum suction force can be formed in the first cavity 331 by a vacuum device, thereby adsorbing and fixing the first tape. In addition, the pickup 33 is driven to rotate vertically and circumferentially by the first drive, which can realize the unwinding of the spare material roll 7.

[0154] Preferably, such as Figure 8 and Figure 10 As shown, the sidewall of the pickup 33 away from the first axis includes a horizontal part 333 and an inclined part 334. One end of the inclined part 334 is connected to one end of the horizontal part 333. The inclined part 334 is inclined upward relative to the horizontal part 333. Multiple second through holes 332 are provided on both the horizontal part 333 and the inclined part 334.

[0155] When the pickup component 33 picks up the head of the spare material strip 12, the first tape is first adsorbed onto the side wall of the pickup component 33, and then the first tape is pasted onto the head of the spare material strip 12. By setting a horizontal part 333 and an inclined part 334 at the bottom of the pickup component 33, one end of the first tape is adsorbed onto the inclined part 334. This part of the tape is not pasted with the spare material strip 12. Only one end of the tape located at the horizontal part 333 is pasted onto the head of the spare material strip 12, so that the head of the spare material strip 12 can be driven away from the material strip roll under the drive of the first drive component, thereby smoothly unwinding.

[0156] Preferably, such as Figure 8 and Figure 10 As shown, the pickup member 33 also includes an arcuate portion 335, one end of which is connected to the other end of the horizontal portion 333, and the arcuate portion 335 is curved upward relative to the horizontal portion 333.

[0157] An arc-shaped surface 335 is provided on the pickup part 33. When the pickup part 33 rotates, its arc-shaped surface 335 contacts the spare material roll 7, which can prevent the spare material strip 12 from being scratched.

[0158] Preferably, such as Figure 8 and Figure 10 As shown, the first pickup device 3 also includes a clamping mechanism 34, which is mounted on the side wall of the pickup member 33 near the inclined portion 334 and is rotatable relative to the pickup member 33.

[0159] After the pickup component 33 picks up the first tape, the clamping mechanism 34 can clamp the first tape adsorbed on the inclined portion 334, thereby preventing the first tape and the spare material tape 12 from detaching from the pickup component 33 and improving the stability of the pickup component 33 in adsorbing the first tape.

[0160] It should be noted that the present invention does not impose any restrictions on the specific structure of the clamping mechanism 34, as long as the clamping mechanism 34 can clamp the first tape adsorbed on the pickup member 33. In practical applications, those skilled in the art can set the specific structure of the clamping mechanism 34 according to actual needs. Adjustments and changes to the specific structure of the clamping mechanism 34 do not deviate from the basic principles of the present invention and should be limited to the protection scope of the present invention.

[0161] Preferably, such as Figure 8 and Figure 10 As shown, the clamping mechanism 34 includes a claw 341, a second shaft (not shown in the figure), and a second drive member (not shown in the figure). One end of the claw 341 is pivotally connected to the side wall near the inclined portion 334 via the second shaft. The second drive member is connected to the claw 341 and can drive the claw 341 to rotate around the second shaft, thereby enabling the claw 341 to rotate vertically in the circumferential direction, so that the other end of the claw 341 can abut against the inclined portion 334 to clamp the first tape onto the inclined portion 334.

[0162] The clamping mechanism 34 is configured with a hook 341, a second shaft, and a second drive component. The second drive component can drive the hook 341 to rotate, thereby clamping the first tape and the spare tape 12. This configuration is simple in structure and easy to assemble and use.

[0163] Preferably, such as Figure 8 and Figure 10 As shown, a clamping roller 342 is provided at the other end of the hook claw 341. An anti-stick coating is provided on the roller surface of the clamping roller 342. When the other end of the hook claw 341 abuts against the inclined part 334, the clamping roller 342 clamps the first tape between the clamping roller 342 and the inclined part 334.

[0164] By setting the clamping roller 342, the contact area can be increased, thereby improving the clamping effect. In addition, the anti-stick coating on the surface of the clamping roller 342 can prevent the roller surface from sticking to the adhesive surface of the first tape, making it easy to separate the clamping roller 342 from the first tape and making it convenient to use.

[0165] It should be noted that the present invention does not impose any restrictions on the relative positions of the first pickup device 3, the spare material roll 7, and the working material roll 6, as long as the first pickup device 3 can pick up the head of the spare material roll 7 and achieve smooth connection between the spare material belt 12 and the working material belt 11. In practical applications, those skilled in the art can set the specific positions of the first pickup device 3, the spare material belt 12, and the working material belt 11 according to actual needs. Adjustments and changes to the specific positions of the first pickup device 3, the spare material roll 7, and the working material roll 6 do not deviate from the basic principles of the present invention and should all be limited to the protection scope of the present invention.

[0166] In a preferred embodiment, two first picking devices 3 can be configured, with the inclined portions 334 of the two first picking devices 3 arranged opposite each other. The two first picking devices 3 can be used together to pick up the material heads with different unwinding directions. With the rotatable pressing device 4, it can realize the tape splicing operation in different left and right directions, thereby increasing the scope of application.

[0167] In another preferred embodiment, such as Figure 8 As shown, the first picking device 3 also includes a third rotating mechanism 35, which is disposed between the sliding device 2 and the first connecting member 31. The third rotating mechanism 35 is configured to drive the first connecting member 31 to rotate around the vertical axis, that is, to enable the first connecting member 31 to rotate horizontally.

[0168] By setting a third rotating mechanism 35, the first connecting member 31 can be rotated, thereby rotating the docking direction of the pickup member 33 by 180 degrees. This changes the bonding direction of the first tape adsorbed by the first pickup device 3, enabling the pickup of tape heads with different unwinding directions and facilitating tape splicing in different directions. Thus, only one first pickup device 3 is needed to achieve the pickup of tape heads with different unwinding directions, resulting in low cost.

[0169] Preferably, such as Figure 8 As shown, the third rotating mechanism 35 includes a third connecting member 351, a third shaft (not shown in the figure), a fourth connecting member 352, a fourth shaft (not shown in the figure), a seventh driving member (not shown in the figure), and an eighth driving member (not shown in the figure). The third shaft and the fourth shaft are both vertical shafts.

[0170] In this configuration, one end of the third connecting member 351 is pivotally connected to the first connecting member 31 via a third axis. The seventh driving member is connected to the side wall of the first connecting member 31 away from the first axis and can drive the first connecting member 31 to rotate around the third axis, i.e., enable the first connecting member 31 to rotate horizontally. The fourth connecting member 352 is fixedly mounted on the sliding device 2. The other end of the third connecting member 351 is pivotally connected to the fourth connecting member 352 via a fourth axis. The eighth driving member is connected to the other end of the third connecting member 351 and can drive the third connecting member 351 to rotate around the fourth axis, i.e., enable the third connecting member to rotate horizontally.

[0172] It should also be noted that the present invention does not impose any limitations on the specific structure of the second adhesive applicator 8. As long as the second adhesive applicator 8 can absorb the third adhesive tape and adhere it to the other side of the spare material strip 12 and the working material strip 11, it is sufficient. In practical applications, those skilled in the art can customize the specific structure of the second adhesive applicator 8 according to actual needs. For example, the second adhesive applicator 8 can be configured as a cylinder + adhesive block structure, or it can be configured as a sliding mechanism + adhesive block structure, so that the adhesive block can change its adhesive application position under the action of the sliding mechanism, and so on. Such adjustments and changes to the specific structure of the second adhesive applicator 8 do not deviate from the basic principles of the present invention and should all be limited to the protection scope of the present invention.

[0173] Preferably, such as Figure 1 and Figure 6 As shown, the second adhesive applicator 8 includes a second cylinder 81 and a second adhesive applicator block 82.

[0174] The second cylinder 81 is connected to the pressing device 4 and is located below the pressing device 4.

The second adhesive block 82 has a third cavity (not shown in the figure) inside. The side wall of the second adhesive block 82 has a third through hole (not shown in the figure) that communicates with the third cavity. The third cavity is connected to a vacuum device so that a vacuum suction force is formed inside the third cavity under the action of the vacuum device, thereby adsorbing the third tape onto the side wall of the second adhesive block 82.

[0175] The second adhesive applicator 8 is configured as a second cylinder 81 and a second adhesive block 82. The second adhesive block 82 has a third cavity, and the side wall of the second adhesive block 82 has a third through hole communicating with the third cavity.

This configuration is simple in structure, easy to set up, and has strong adsorption force.

[0176] Preferably, such as Figures 1 to 3 As shown, the tape changing device of the present invention further includes a glue preparation device 9, which is configured to obtain a tape 13 of a preset length and to prepare the tape 13 of the preset length to the first picking device 3, the first applying device 14 and the second applying device 8 respectively, so as to form a first tape, a second tape and a third tape respectively.

[0177] By setting up the glue preparation device 9, automatic glue preparation can be achieved, saving labor and improving production efficiency.

[0178] Preferably, such as Figure 3 As shown, the adhesive preparation device 9 includes a tape output mechanism 91, a third sliding mechanism 92, and a tape feeding mechanism 93.

When the tape feeding mechanism 93 moves to a position close to the tape 13, the tape feeding mechanism 93 adsorbs and fixes the tape 13 and obtains a tape 13 of a preset length. Then, under the drive of the third sliding mechanism 92, the adsorbed tape 13 of the preset length is transferred to the first picking device 3, the first adhesive applicator 14 or the second adhesive applicator 8 to form a first tape, a second tape or a third tape.

[0181] Preferably, such as Figure 3 As shown, the tape feeding mechanism 93 includes a third cylinder 931, a rotary cylinder 932, a transfer block 933, and a tape cutter (not shown in the figure).

The fourth cavity is connected to a vacuum device so that a vacuum suction force is formed inside the fourth cavity under the action of the vacuum device, thereby adsorbing the tape 13 onto the side wall of the transfer block 933. The tape cutter is mounted on the rotary cylinder 932 and is configured to cut the tape 13 after the transfer block 933 adsorbs the tape 13, thereby obtaining a tape 13 of a preset length.

[0183] The tape feeding mechanism 93 is configured as a third cylinder 931, a rotary cylinder 932, a transfer block 933, and a tape cutting component. It has a simple structure, is easy to assemble and use, occupies a small volume, and is easy to control.

[0185] By setting a third driving component, the second adhesive applicator 8 can be rotated, which can change the orientation of the second adhesive block 82 so that it can dock with the transfer block 933 to receive the tape 13, thereby forming the third tape.

[0186] It should be noted that the present invention does not impose any restrictions on the specific structure of the cutting device 5, as long as the cutting device 5 can cut the working material strip 11 so that the pasted spare material strip 12 becomes the new working material strip 11. In practical applications, those skilled in the art can set the specific structure of the cutting device 5 according to actual needs.

[0187] Preferably, the cutting device 5 includes a fourth cylinder and a first cutting blade. The fourth cylinder is mounted on the pressing block 42, and the first cutting blade is mounted on the end of the piston rod of the fourth cylinder. The first cutting blade is located below the pressing block 42.

[0188] The cutting device 5 is configured with a fourth cylinder and a first cutting blade. The first cutting blade is moved by the fourth cylinder to perform cutting. The structure is simple, easy to assemble and use, and easy to control.

[0189] It should be noted that the present invention does not impose any restrictions on the specific structure of the tape cutter. As long as the tape cutter can cut the tape 13 into tape 13 of a preset length, it is acceptable. In practical applications, those skilled in the art can set the specific structure of the tape cutter according to actual needs.

[0190] Preferably, the tape cutting component includes a fifth cylinder and a second cutting blade. The fifth cylinder is mounted on a rotary cylinder 932, and the second cutting blade is mounted on the end of the piston rod of the fifth cylinder.

[0191] The tape cutting component is configured as a fifth cylinder and a second cutting blade. The fifth cylinder controls the second cutting blade for cutting. The structure is simple, easy to assemble and use, and easy to control.

[0192] It should be noted that this invention does not impose any restrictions on the specific structure of the third sliding mechanism 92, as long as the third sliding mechanism 92 can drive the tape feeding mechanism 93 to move. In practical applications, those skilled in the art can customize the specific structure of the third sliding mechanism 92 according to actual needs. For example, the third sliding mechanism 92 can be configured as a linear sliding module, or it can be configured as a structure where a drive component drives a gear to move a rack, or it can be configured as a structure where a ball screw and a slider cooperate, and so on. Such adjustments and changes to the specific structure of the third sliding mechanism 92 do not deviate from the basic principles of this invention and should all be limited to the protection scope of this invention.

[0193] Finally, it should be noted that this invention does not impose any limitations on the specific structure of the driving component described above. In practical applications, those skilled in the art can customize the specific structure of the driving component according to actual needs. For example, the driving component can be configured as a servo motor, or it can be configured as a stepper motor, and so on. Such adjustments and changes to the specific structure of the driving component do not deviate from the basic principles of this invention and should all be limited to the scope of protection of this invention.

[0194] When the belt switching device of the present invention performs belt splicing operation, the specific belt splicing process includes the following two scenarios.

[0195] Scenario 1

[0196] In this scenario, the tape changing equipment in both Embodiment 1 and Embodiment 2 can achieve double-sided adhesive tape splicing. The specific splicing scenarios include the following: ① The left side is a spare roll 7, which is unwound clockwise, and the right side is a working roll 6, which is also unwound clockwise; ② The left side is a spare roll 7, which is unwound clockwise, and the right side is a working roll 6, which is unwound counter-clockwise; ③ The left side is a working roll 6, which is unwound clockwise, and the right side is a spare roll 7, which is unwound counter-clockwise; ④ The left side is a working roll 6, which is unwound counter-clockwise, and the right side is a spare roll 7, which is unwound counter-clockwise.

[0197] like Figure 11 As shown, the specific process of the belt switching device of the present invention in case 1 is specifically explained using case ① as an example.

[0198] First, refer to Figure 11 In (1), the first picking device 3 adsorbs the first tape and reaches the material preparation position, so that one end of the first tape is attached to the material head of the spare material tape 12, thereby picking up the material head of the spare material tape 12.

[0199] Secondly, refer to Figure 11 In (2), the first picking device 3, carrying the first tape and the spare tape 12, arrives at the tape receiving position for standby.

[0200] Again, refer to Figure 11 In step (3), the pressing device 4 pushes the working material strip 11 to move, and the pressing device 4 docks with the first picking device 3 to stick one side of the working material strip 11 to the other end of the first tape. After sticking, the cutting device 5 cuts the working material strip 11; then the pressing device 4 returns.

[0201] Again, refer to Figure 11 In step (4), the second adhesive applicator 8 moves with the third tape and docks with the first pickup device 3 to stick the third tape on the other side of the working material belt 11 and the spare material belt 12.

[0202] Finally, the second adhesive applicator 8 returns to its original position, thus completing the tape connection operation, and the spare tape 12 becomes the new working tape 11 for continued use.

[0203] Scenario 2

[0204] In this splicing scenario, only the belt changing device in Example 2 can achieve double-sided adhesive splicing. This splicing scenario specifically includes the following situations: ⑤ The left side is the working material roll 6, which is unwound clockwise, and the right side is the spare material roll 7, which is unwound clockwise; ⑥ The left side is the working material roll 6, which is unwound counterclockwise, and the right side is the spare material roll 7, which is unwound clockwise; ⑦ The left side is the spare material roll 7, which is unwound counterclockwise, and the right side is the working material roll 6, which is unwound clockwise; ⑧ The left side is the spare material roll 7, which is unwound counterclockwise, and the right side is the working material roll 6, which is unwound counterclockwise.

[0205] like Figure 12 As shown, taking case ⑥ as an example, the specific process of the belt switching device of the present invention in case one is specifically explained as follows: Figure 12 The following describes the second scenario of the connection.

[0206] First, refer to Figure 12 In (1), the first picking device 3 adsorbs the first tape and reaches the material preparation position, so that one end of the first tape is attached to the material head of the spare material tape 12, thereby picking up the material head of the spare material tape 12.

[0207] Secondly, refer to Figure 12 In (2), the first picking device 3, carrying the first tape and the spare tape 12, docks with the first adhesive applicator 14 located at the tape receiving position, and sticks the other end of the first tape to one end of the second tape, so that the first adhesive applicator 14 can fix the spare tape 12 and place it at the tape receiving position for later use.

[0208] Again, refer to Figure 12 In step (3), the pressing device 4 pushes the working material strip 11 to move, and the pressing device 4 docks with the first adhesive applicator 14 to stick one side of the working material strip 11 to the other end of the second adhesive strip. After sticking, the cutting device 5 cuts the working material strip 11; then the pressing device 4 returns.

[0209] Again, refer to Figure 12 In step (4), the second adhesive applicator 8 moves with the third adhesive tape and docks with the first adhesive applicator 14, sticking the third adhesive tape to the other side of the working material belt 11 and the first adhesive tape.

[0210] Finally, the second adhesive applicator 8 returns to its original position, thus completing the tape connection operation, and the spare tape 12 becomes the new working tape 11 for continued use.

[0211] Based on the belt changing equipment described above, the present invention also provides a belt changing method to realize the belt changing between the spare material belt 12 and the working material belt 11.

[0212] Example 1

[0213] The belt changing method of this embodiment is applicable to the belt changing equipment of any of the above embodiments.

[0214] Specifically, such as Figure 13 As shown, the belt changing method of the present invention includes the following steps:

[0215] S100: The sliding device 2 moves the first pickup device 3, which has the first tape adsorbed, to the spare material belt 12.

[0216] S200: The first pickup device 3 attaches one end of the first adhesive tape to one side of the starting end of the spare material tape 12.

[0217] S300: The sliding device 2 drives the first pickup device 3, which has adsorbed the first tape and the spare material tape 12, to move.

[0218] S400: The pressing device 4 pushes the working material strip 11 to move and docks with the first picking device 3 to stick one side of the working material strip 11 to the other end of the first adhesive tape.

[0219] S500: The cutting device 5 cuts the working strip 11.

[0220] The belt changing method of the present invention automatically picks up the material head by setting the first picking device 3, saving the time of manual picking up of the material head. In addition, after the pressing device 4 pushes the working material belt 11 to move and sticks it with the first adhesive tape, the cutting device 5 cuts the working material belt 11 in time. The time required for sticking the material belt in the whole process is short, which can be completed within 1-2 seconds, thereby realizing non-stop operation and effectively improving work efficiency.

[0221] Preferably, when the belt changing equipment includes a second adhesive applicator, the belt changing method further includes the following step: S600: The second adhesive applicator 8 applies a third adhesive tape to the other side of the working material belt 11 and the spare material belt 12.

[0222] When the second adhesive applicator 8 is provided, after the cutting device 5 cuts the working strip 11, the second adhesive applicator 8 applies the third adhesive tape to the other side of the working strip 11 and the spare strip 12, thereby achieving double-sided adhesive application. This improves the firmness of the joint position, and the adhesive application time is short, allowing for non-stop operation.

[0223] Example 2

[0228] S300: The sliding device 2 drives the first picking device 3, which has adsorbed the first tape and the spare tape 12, to move, so that the first picking device 3 docks with the first adhesive device 14, thereby sticking the other end of the first tape to one end of the second tape.

[0229] S400: The pressing device 4 pushes the working material strip 11 to move and docks with the first adhesive applicator 14 to stick one side of the working material strip 11 to the other end of the second adhesive strip.

[0230] S500: The cutting device 5 cuts the working strip 11.

[0231] The tape changing method of the present invention automatically picks up the material head by setting up a first picking device 3 and sticks the picked-up spare material tape 12 onto the second adhesive tape for later use, saving the time of manual picking up of the material head. In addition, after the pressing device 4 pushes the working material tape 11 to move and sticks it to the second adhesive tape, the cutting device 5 cuts the working material tape 11 in time. The time required for pasting the material tape in the whole process is short, which can be completed within 1-2 seconds, thereby realizing non-stop operation and effectively improving work efficiency.

[0232] Preferably, when the belt changing equipment includes a second adhesive applicator, the belt changing method further includes the following step: S600: The second adhesive applicator 8 applies a third adhesive tape to the other side of the working material belt 11 and the spare material belt 12.

[0233] When the second adhesive applicator 8 is provided, after the cutting device 5 cuts the working strip 11, the second adhesive applicator 8 applies the third adhesive tape to the other side of the working strip 11 and the spare strip 12, thereby achieving double-sided adhesive application, which improves the firmness of the joint position, and the adhesive application time is short, allowing for non-stop operation.
