Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape production, and in particular to a high-efficiency stripping device and a processing technology for producing PI adhesive tape. Background Art

[0002] PI tape, full name polyimide tape, is based on polyimide film and has the characteristics of high temperature resistance, chemical corrosion resistance, good electrical insulation performance, excellent mechanical properties, etc. It is soft and bendable, and its color is generally amber (brown).

[0003] PI tape is mainly used in the electronic and electrical industry. For example, in the SMT process, it is used to stick thermocouple wires when measuring the temperature of the reflow furnace, and to stick flexible circuit boards on fixtures; it can be wrapped on cables as insulating tape; it can be attached to connectors for SMT machine material collection, etc. It is also used in aerospace, automotive industry, new energy and other fields.

[0004] During the tape slitting operation, the slitting machine needs to manually take out the tape raw material tube on the material roller and put in a new tape raw material tube after completing the slitting operation. The general material replacement direction of this operation is horizontal, that is, the tape raw material tube will be discharged outward along the axis direction of the material roller. Whether it is automatic material replacement or manual material replacement, it needs to be replaced in the horizontal direction. This operation method requires a large replacement area, which will affect the layout of factory equipment and occupy a large area.

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] like Figure 1-10 The high-efficiency slitting equipment for PI tape production shown in the figure comprises an installation roller 1 for installing a tape raw material tube, and also comprises a rotating shaft 2, a center clamping mechanism 3, an outward-expanding clamping mechanism 4, a driving mechanism 5 and a turning frame 6. One end of the installation roller 1 is axially connected to the turning frame 6 which can be turned over. The rotating shaft 2 is coaxially installed inside the installation roller 1. The center clamping mechanism 3 and the outward-expanding clamping mechanism 4 are both installed inside the installation roller 1. The driving mechanism 5 is installed on the turning frame 6 and is transmission-connected with the rotating shaft 2, the center clamping mechanism 3 and the outward-expanding clamping mechanism 4. The center clamping mechanism 3 comprises two groups of end clamping assemblies 31 respectively installed at both ends of the installation roller 1 and a first transmission assembly 32 for transmission-connecting the two groups of end clamping assemblies 31. The end clamping assembly 31 comprises a plurality of turning clamping claws 311 annularly distributed around the axis of the installation roller 1. The turning clamping claws 311 can The mounting roller 1 is capable of sliding along the axial direction of the mounting roller 1, and first horizontal slots 11 are provided at both ends of the outer wall of the mounting roller 1 for the flip clamping claw 311 to move. The end of the flip clamping claw 311 can be flipped ninety degrees and then extend out of the first horizontal slot 11 to contact the end of the tape raw material tube. The outward expansion clamping mechanism 4 includes a plurality of groups of inner wall clamping components 41 distributed in a ring around the axis of the mounting roller 1 and a second transmission component 42 installed on the rotating shaft 2 and transmission connected to the plurality of groups of inner wall clamping components 41. The inner wall clamping component 41 includes an outward expansion contact frame 411 capable of expanding and contracting on the mounting roller 1, and a transmission groove matching the outward expansion contact frame 411 is provided on the inner wall of the tape raw material tube. The rotating shaft 2 is transmission-connected to the outward expansion clamping mechanism 4, and a second horizontal slot 12 is provided on the middle outer wall of the mounting roller 1 for the outward expansion contact frame 411 to slide.

[0036] The equipment shown in the present invention can automatically carry out the replacement operation of the tape raw material roll of the PI tape. The overall replacement process does not require manual assistance and can carry out the material replacement operation in the vertical direction, greatly reducing the footprint of the equipment. It can realize the automatic centering and automatic clamping functions of the tape raw material roll installed on the outside of the mounting roller 1, and can mobilize the rotation of the tape raw material roll. When unloading is required, the clamping of the tape raw material roll can be automatically released and it can be detached from the mounting roller 1.

[0037] The rotating shaft 2 is arranged in the mounting roller 1. When it is necessary to drive the outward expansion contact frame 411 in the inner wall clamping assembly 41 to contact and clamp the inner wall of the tape raw material tube, the rotating shaft 2 rotates to drive several outward expansion contact frames 411 connected to it to expand outward synchronously to realize the expansion clamping function. When the tape stock roll is replaced, the turning frame 6 is first turned ninety degrees to convert the installation roller 1 from the horizontal state to the vertical state, and the driving mechanism 5 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the center clamping mechanism 3 to reset, and the two sets of end clamping assemblies 31 are driven to reset synchronously through the first transmission assembly 32, and the turning clamping claw 311 first moves to the two ends of the installation roller 1. When it moves to the reset position, the turning clamping claw 311 is turned over until its length direction is consistent with the axial direction of the installation roller 1. At this time, there is no obstruction of the center clamping mechanism 3 at both ends of the installation roller 1, thereby ensuring that the center clamping mechanism 3 will not interfere with the loading and unloading operations of the tape stock roll, and the outward expansion clamping mechanism 4 is reset by the driving mechanism 5, and the inner wall clamping assembly 41 is reset by the second transmission assembly 42, and the outward expansion contact frame 411 retracts to the inside of the installation roller 1. At this time, the outward expansion contact frame 411 is in contact with the inner wall of the tape stock roll. In the touch-connected state, the tape stock roll mounted on the mounting roller 1 can be freely loaded and unloaded. It is worth mentioning that a manipulator for clamping the tape stock roll is installed above or below the equipment, and the manipulator can realize the material replacement operation of the tape stock roll mounted on the mounting roller 1. After the material replacement is completed, the manipulator clamps the new tape stock roll on the mounting roller 1, and the end clamping assembly 31 first flips the flip clamping claw 311 to a state perpendicular to the axial direction of the mounting roller 1. At this time, the manipulator releases the clamping of the tape stock roll, and the tape stock roll will not fall out of the mounting roller 1, but will follow the flip clamping claw 311 to realize the centering function synchronously during the centering process of the end clamping assemblies 31 at both ends. After the centering is completed, the inner wall of the tape stock roll at the center position is clamped by the outward expansion contact frame 411 in the inner wall clamping assembly 41, thereby realizing the overall material replacement function.

[0038] The end clamping assembly 31 also includes a first fixed ring 312, a first push ring 313, a first transmission ring 314, a first sleeve 315, a first transmission connecting rod 316, a first connecting rod 317 and a first spring 318. The first fixed ring 312 is fixedly mounted on the rotating shaft 2, the first push ring 313 is slidably mounted on the rotating shaft 2, the first transmission ring 314 is slidably arranged on the rotating shaft 2, the first transmission ring 314 is located between the first push ring 313 and the first fixed ring 312, the driving mechanism 5 is transmission-connected with the first push ring 313, the first sleeve 315 is fixedly mounted on a side of the first transmission ring 314 close to the first push ring 313, the first push ring 313 and the first sleeve 315 are slidably matched, the sliding between the first push ring 313 and the first sleeve 315 is limited by a limiting ring installed on the first sleeve 315, and the flip clamping claw 3 The end of 11 away from the first transmission ring 314 is the clamping end, and a pressure sensor is provided on the clamping end of the flip clamping claw 311. One end of the first transmission connecting rod 316 is hinged to the middle part of the flip clamping claw 311, and the other end of the first transmission connecting rod 316 is hinged to the first push ring 313. A plurality of first connecting rods 317 and first springs 318 are provided and are distributed in a ring around the axis of the rotating shaft 2. The first connecting rod 317 is installed between the first transmission ring 314 and the first fixed ring 312. The first spring 318 is sleeved on the first connecting rod 317, and the two ends of the first spring 318 are fixedly connected to the side walls of the first transmission ring 314 and the first fixed ring 312 respectively. The first push ring 313 in one group of end clamping assemblies 31 is transmission-connected to the driving mechanism 5, and the first push ring 313 in another group of end clamping assemblies 31 is transmission-connected to the first transmission assembly 32.

[0039] When the first pushing ring 313 is driven by the driving mechanism 5 or the first transmission assembly 32, the first pushing ring 313 moves toward the direction close to the first fixed ring 312. When the first pushing ring 313 is displaced, the first transmission connecting rod 316 hinged thereto is driven to deflect. The first transmission connecting rod 316 drives the flip clamping claw 311 hinged thereto to deflect, thereby flipping the flip clamping claw 311 out of the installation roller 1. After that, the first pushing ring 313 continues to be pushed to move. The first pushing ring 313, the first transmission ring 314 and the first sleeve 315 form a whole and synchronously displace toward the direction close to the first fixed ring 312, compressing the first connecting rod 317 and the first spring 318. It is worth mentioning that the first connecting rod 317 is a telescopic rod, and its length can change according to the distance between the first fixing ring 312 and the first transmission ring 314, thereby realizing the sliding function of the flip clamping claw 311 relative to the mounting roller 1, and the flip clamping claws 311 at both ends synchronously move toward the center, realizing the function of center clamping, and the first spring 318 can provide elastic force to ensure that when the flip clamping claw 311 is not flipped, there will be no synchronous displacement between the first push ring 313 and the first transmission ring 314, thereby realizing the relative sliding between the first push ring 313 and the first transmission ring 314, that is, the flip clamping claw 311 is driven to deflect through the first transmission connecting rod 316. When resetting, the first spring 318 is first released to drive the first push ring 313 and the first transmission ring 314 to move synchronously toward the two ends of the installation roller 1. At this time, the flip clamping claw 311 does not deflect. After the elastic force is released, the first push ring 313 continues to move toward the two ends, and the first push ring 313 and the first transmission ring 314 slide relative to each other, thereby driving the flip clamping claw 311 to deflect and reset. In the above clamping process, the pressure sensor on the flip clamping claw 311 can detect the clamping force on the end of the tape raw material tube.

[0040] The centering clamping mechanism 3 also includes a first linear drive 33 and a first push rod 34. The first transmission assembly 32 includes a second push rod 321, a hydraulic pipe 322, a mounting plate 323 and a third push rod 324. The first linear drive 33 is fixedly mounted on the flip frame 6. The output direction of the first linear drive 33 and the length direction of the first push rod 34 are consistent with the axial direction of the mounting roller 1. One end of the first push rod 34 is fixedly connected to one end of a first push ring 313 in a group of end clamping assemblies 31 close to the flip frame 6. The other end of the first push rod 34 is transmission-connected to the first linear drive 33 through a turntable. The output end of the first linear drive 33 is fixedly connected to the turntable. A sliding ring is provided on the turntable for the end of the first push rod 34 to rotate and slide. The transmission assembly 32 is arranged at one end of the mounting roller 1 away from the first linear drive 33, the mounting plate 323 is fixedly mounted in the mounting roller 1, the oil pressure tube 322 is fixedly mounted on the mounting plate 323, the oil pressure tube 322 is U-shaped, and the two opening directions of the oil pressure tube 322 both point to the first linear drive 33, one end of the second push rod 321 is fixedly connected to the first push ring 313 in another group of end clamping assemblies 31, the other end of the second push rod 321 is sealed and slidably matched with one end of the oil pressure tube 322, the third push rod 324 is sealed and slidably matched with the other end of the oil pressure tube 322, and the end of the third push rod 324 away from the oil pressure tube 322 is fixedly connected to the first push ring 313 in a group of end clamping assemblies 31 away from the first linear drive 33.

[0041] During transmission, the pushing force of the first push ring 313 in one group of the end clamping assemblies 31 can be transmitted to the oil pressure pipe 322 through the second push rod 321, and the second push rod 321 squeezes the oil pressure pipe 322 and drives the third push rod 324 to push outward synchronously. The third push rod 324 drives the first push ring 313 in the other group of the end clamping assemblies 31 to also realize the pushing and squeezing function. When the first linear driver 33 outputs, the first push rod 34 realizes the driving function of the first push ring 313. One end of the first push rod 34 is fixedly connected to one end of the first push ring 313 in a group of the end clamping assemblies 31 close to the flip frame 6, and the other end of the first push rod 34 is connected to the first linear driver 33 through a rotating disk. The output end of the first linear driver 33 is fixedly connected to the rotating disk, and a sliding ring is provided on the rotating disk for the end of the first push rod 34 to rotate and slide. It can ensure that when the mounting roller 1 and the rotating shaft 2 rotate, the first push ring 313 and the first push rod 34 are always in a transmission connection state when the end clamping assembly 31 rotates.

[0042] The inner wall clamping assembly 41 also includes a limit plate 412, a transmission plate 413, a second connecting rod 414 and a second spring 415. The limit plate 412 is fixedly installed at both ends of the outward expansion contact frame 411, and the limit plate 412 can fit with the inner side wall of the installation roller 1. The transmission plate 413 can be slidably set in the outward expansion contact frame 411. The sliding direction of the transmission plate 413 is consistent with the radial length direction of the installation roller 1. The second connecting rod 414 is fixedly installed in the outward expansion contact frame 411. The second spring 415 is sleeved on the second connecting rod 414. The second connecting rod 414 and the transmission plate 413 are slidably matched. One end of the second spring 415 is fixedly connected to the outward expansion contact frame 411, and the other end of the second spring 415 is fixedly connected to the transmission plate 413. The second transmission assembly 42 is transmission-connected to the transmission plate 413.

[0043] When the driving mechanism 5 drives the outward expansion contact frame 411 through the second transmission component 42, the transmission plate 413 is driven to move through the second transmission component 42, and then the outward expansion contact frame 411 is driven to expand or contract synchronously outwardly through the elastic force of the second spring 415. When the outward expansion contact frame 411 expands outward, the outward expansion contact frame 411 passes through the second horizontal slot 12 and moves outward, and the limit plate 412 is in contact with the inner wall of the mounting roller 1, and the limit plate 412 plays a limiting function on the displacement of the outward expansion contact frame 411. At this time, in order to improve the clamping stability of the outward expansion contact frame 411, the transmission plate 413 continues to move to compress the second spring 415. At this time, the outward expansion contact frame 411 receives the outward elastic force of the second spring 415, so that the outward expansion contact frame 411 is firmly in contact with the mounting roller 1, thereby ensuring the stability of the clamping transmission and avoiding loosening during the clamping process.

[0044] The second transmission assembly 42 includes a first threaded sliding seat 421, a second connecting rod 422 and a limiting rod 423. There are two first threaded sliding seats 421, and each first threaded sliding seat 421 is provided with a plurality of second connecting rods 422. One end of the second connecting rod 422 is hinged to the first threaded sliding seat 421, and the other end of the second connecting rod 422 is transmission-connected to the transmission plate 413 in the inner wall clamping assembly 41. The limiting rod 423 is fixedly installed in the mounting roller 1, and the length direction of the limiting rod 423 is consistent with the axial direction of the mounting roller 1. The first threaded sliding seat 421 and the limiting rod 423 are slidingly connected. Two-way threads 21 are provided on both ends of the rotating shaft 2, and the first threaded sliding seat 421 is threadedly matched with the rotating shaft 2 through the two-way threads 21.

[0045] When the rotating shaft 2 rotates, the first threaded sliding seat 421 is threadedly matched with the bidirectional thread 21, so that the first threaded sliding seat 421 is displaced inside the mounting roller 1 along the axial direction of the mounting roller 1, and the limiting rod 423 guides and limits the displacement of the first threaded sliding seat 421. When the first threaded sliding seat 421 slides relative to the outward-expanded abutment frame 411, the first threaded sliding seat 421 drives the second connecting rod 422 to deviate, and then drives the transmission plate 413 hinged to the second connecting rod 422 to displace, thereby realizing the driving function.

[0046] The second transmission assembly 42 also includes a central rotating sleeve 425, a transmission latch 426, a second threaded sliding seat 427 and a third connecting rod 428. The central column 424 is installed in the middle of the mounting roller 1. The central column 424 and the limiting rod 423 are fixedly connected. The central rotating sleeve 425 can be rotatably installed on the central column 424. The second threaded sliding seat 427 is provided with two and is respectively located at both ends of the central rotating sleeve 425. The outer wall of the central rotating sleeve 425 is provided with two-way external threads at both ends. The central rotating sleeve 425 is respectively connected to the central rotating sleeve 425 through the two-way external threads. The two second threaded sliding seats 427 are threadedly matched, the second threaded sliding seats 427 and the limit rod 423 are slidably connected, a transmission tooth 426 is installed on the inner wall of the central rotating sleeve 425, and a central transmission groove 22 is provided in the middle of the rotating shaft 2 for transmission connection with the transmission tooth 426. A plurality of third connecting rods 428 are provided on the outer wall of each second threaded sliding seat 427 and are distributed in a ring around the axis of the rotating shaft 2. One end of the third connecting rod 428 is hinged to the outer wall of the second threaded sliding seat 427, and the other end of the third connecting rod 428 is hinged to the transmission plate 413.

[0047] During the transmission process of the second transmission component 42, the rotation of the rotating shaft 2 drives the central rotating sleeve 425 to rotate synchronously. The rotating shaft 2 realizes the transmission connection with the central rotating sleeve 425 through the central transmission groove 22 and the transmission tooth 426. When the central rotating sleeve 425 rotates, it drives the second threaded sliding seat 427 that is threadedly matched with it to slide. When sliding, the second threaded sliding seat 427 drives the third connecting rod 428 to deflect, and then drives the transmission plate 413 to move through the third connecting rod 428, which can support the middle part of the transmission plate 413 and improve the overall expansion stability.

[0048] The driving mechanism 5 includes a rotating driving component 51 and a rotating clamping driving component 52. The rotating driving component 51 is connected to the installation roller 1 by transmission, and the rotating clamping driving component 52 is connected to the rotating shaft 2 by transmission. The rotating driving component 51 is installed on the turning frame 6, and the rotating clamping driving component 52 is arranged at the end of the installation roller 1 away from the turning frame 6. The outward-expanding clamping mechanism 4 also includes an axis end clamping component 43 installed at the end of the rotating shaft 2 away from the turning frame 6. The axis end clamping component 43 includes a fixed frame 431, a third spring 432, a sliding block 433, a semi-annular friction plate 434, a driving frame 435 and an unlocking block 436. The fixed frame 431 is fixedly installed at the end of the rotating shaft 2. The third spring 432, two sliding blocks 433 and two semi-annular friction plates 434 are provided and are respectively located at the two ends of the fixed frame 431, the sliding block 433 is slidably arranged on the fixed frame 431, the two ends of the third spring 432 are respectively fixedly connected to the fixed frame 431 and the sliding block 433, the sliding block 433 is provided with a first transmission inclination angle, the semi-annular friction plate 434 is fixedly connected to the sliding block 433, the semi-annular friction plate 434 can fit with the outer wall of the rotating shaft 2, the driving frame 435 is horizontally displaced and arranged on the side of the mounting roller 1 away from the end of the flip frame 6, and an unlocking block 436 is fixedly installed on the driving frame 435, and the unlocking block 436 can be connected with the sliding block 433 in contact.

[0049] When the rotating clamping drive assembly 52 drives the rotating shaft 2 to rotate, the shaft end clamping assembly 43 is required to release the clamping state of the rotating shaft 2. When there is no need to rotate the rotating shaft 2, the rotating shaft 2 remains connected to the mounting roller 1 through the shaft end clamping assembly 43, ensuring that when the mounting roller 1 rotates, the rotating shaft 2 rotates synchronously with the mounting roller 1, thereby ensuring that the outward expansion clamping mechanism 4 driven by the rotating shaft 2 remains stable, and the sliding block 433 presses the semi-annular friction plate 434 against the outer wall of the rotating shaft 2 through the elastic force of the third spring 432. When unlocking is required, the unlocking block 436 is driven to move by the driving frame 435, and the unlocking block 436 is inserted into the fixed frame 431, and the third spring 432 is compressed to force the sliding block 433 and the semi-annular friction plate 434 to retract, so that the rotating shaft 2 can rotate relative to the mounting roller 1.

[0050] The rotation drive assembly 51 includes a first rotation driver 511, a driving gear 512 and a driven gear 513. The first rotation driver 511 is fixedly mounted on the flip frame 6, the driving gear 512 is fixedly mounted on the output end of the first rotation driver 511, and the driven gear 513 is fixedly mounted on the outer wall of the mounting roller 1, and the driving gear 512 and the driven gear 513 are meshed.

[0051] When the first rotary driver 511 outputs, it drives the driving gear 512 to rotate. When the driving gear 512 rotates, it drives the driven gear 513 meshing with it to rotate, and then drives the installation roller 1 fixedly connected to the driven gear 513 to rotate synchronously, thereby realizing the rotary driving function.

[0052] The rotary clamping drive assembly 52 includes a pin 521 and a second rotary driver 522. A socket 23 for inserting the pin 521 is provided on the end of the rotating shaft 2. The second rotating driver 522 is fixedly mounted on the unlocking block 436. The pin 521 is rotatably arranged on the unlocking block 436. The pin 521 is fixedly connected to the output end of the second rotary driver 522. The pin 521 is transmission-connected to the rotating shaft 2 via the socket 23.

[0053] When the unlocking block 436 approaches the end of the rotating shaft 2 and unlocks the shaft end clamping assembly 43, the plug post 521 installed on the unlocking block 436 is inserted into the socket 23 to realize the transmission connection relationship with the rotating shaft 2. At this time, the second rotation driver 522 drives the plug post 521 to rotate, thereby realizing the rotation driving function of the rotating shaft 2.

[0054] An efficient striping process for producing PI tape includes the following steps:

[0055] S1: First, the installation roller 1 is turned 90 degrees by the turning frame 6 to convert the installation roller 1 from the horizontal state to the vertical state, the driving mechanism 5 drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the center clamping mechanism 3 to reset, and the two sets of end clamping assemblies 31 are driven to reset synchronously by the first transmission assembly 32, and the turning clamping claw 311 first moves to the two ends of the installation roller 1. When it moves to the reset position, the turning clamping claw 311 is turned so that its length direction is consistent with the axis direction of the installation roller 1;

[0056] S2: The outward expansion clamping mechanism 4 is driven to reset through the driving mechanism 5, and the inner wall clamping assembly 41 is driven to reset through the second transmission assembly 42, and the outward expansion contact frame 411 is retracted to the inside of the installation roller 1. At this time, the outward expansion contact frame 411 is in contact and engagement with the inner side wall of the tape raw material tube, and the initial tape raw material tube unloading work is performed;

[0057] S3: The robot arm can be used to replace the tape raw material roll mounted on the installation roller 1. After the replacement is completed, the robot arm clamps the new tape raw material roll on the installation roller 1, and the end clamping assembly 31 first flips the flip clamping claw 311 to a state perpendicular to the axial direction of the installation roller 1. At this time, the robot arm releases the clamping of the tape raw material roll, and the tape raw material roll follows the flip clamping claw 311 to synchronously realize the centering function. After the centering is completed, the inner wall of the tape raw material roll in the center position is clamped by the outward-expanding contact frame 411 in the inner wall clamping assembly 41, thereby realizing the overall material replacement function.
