Description

Technical Field

[0001] This invention relates to the field of anti-sticking paper peeling technology, and more specifically to an anti-sticking paper peeling device. Background Technology

[0002] Release paper, also known as release liner, is a specially treated thin film material that primarily serves to isolate sticky objects. It is typically used to cover easily worn workpieces to prevent damage during transport. Before processing, the release paper needs to be manually removed from the workpiece.

[0003] In existing technologies, a workpiece with release paper attached is loaded onto a carrier and moved. When the workpiece is transported to a designated position, it is fixed by a fixing device. Then, the release paper is peeled off the workpiece by a gripper. However, the above-mentioned device has high requirements for the positional accuracy of the workpiece and the gripper. In actual use, misalignment between the gripper's gripping position and the tearing position of the release paper can cause the release paper to fail to be peeled off. There are also cases where the gripper only holds a small area of ​​the release paper, causing the gripper to tear the release paper or the release paper to come loose during the subsequent tearing process, resulting in poor overall reliability. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-sticking paper peeling device, which increases the contact area with the release paper, reduces the requirements for workpiece positional accuracy, facilitates the peeling of the release paper from the workpiece, and improves the overall reliability of the device.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: an anti-sticking paper peeling device for peeling release paper off a workpiece, comprising: a first base frame with a first conveying track mounted on its top, a second base frame with a second conveying track mounted on its top, and an interval area provided between the first base frame and the second base frame, wherein the size of the workpiece is larger than the width of the interval area, so that the workpiece can be transferred between the first conveying track and the second conveying track; A first bracket with a first servo motor is installed at one end of the first base frame near the second base frame. A support plate is set inside the interval area and perpendicular to the first conveying track. This support plate is rotatably connected to the first bracket. A transmission mechanism is provided between the output shaft of the first servo motor and the support plate. A side support plate with a third bracket is installed between the first base frame and the second base frame. A take-up roller, a second guide roller, and an unwind roller are rotatably installed on this side support plate. The second guide roller is located inside the interval area. The take-up roller is located on the side opposite to the first conveying track of the second guide roller. The take-up roller rotates to drive the adhesive tape on the outer wall of the second guide roller to move forward. A fourth guide roller is disposed between the second guide roller and the unwinding roller, and the winding roller is located on the side of the fourth guide roller opposite to the first conveying track; a strip support plate is rotatably mounted on one side of the third bracket relative to the side support plate, and a third guide roller is respectively mounted on the strip support plate on both sides of the fourth guide roller, and a third servo motor is disposed on the side of the third bracket opposite to the side support plate. The strip support plate has two working states. When the strip support plate switches from the first state to the second state, the adhesive tape on the outer wall of the second guide roller moves backward.

[0006] The following are further improvements to the above technical solution: 1. In the above scheme, the transmission mechanism includes: a first support shaft and a second support shaft rotatably mounted on a first bracket, a first gear is fixedly mounted on the upper end of the second support shaft, and its lower end is fixedly connected to the output shaft of the first servo motor. The lower end of the first support shaft is fixedly connected to a backing plate, and a second gear that meshes with the first gear is fixedly mounted on the upper end of the first support shaft.

[0007] 2. In the above scheme, a torsion spring is provided between the second gear and the first gear and on the circumferential outer wall of the first support shaft.

[0008] 3. In the above scheme, a gas spring is vertically installed on one side of the side support plate, and the movable end of the gas spring is fixedly connected to the side support plate.

[0009] 4. In the above scheme, the gas rod and the side support plate are fixedly connected by a second bracket.

[0010] 5. In the above scheme, both the first base frame and the second base frame have a limiting groove with a slider internally slidably connected in the vertical direction, and the second bracket is fixedly connected to the slider.

[0011] 6. In the above scheme, the gas rod is fixedly installed on the top of a base plate.

[0012] 7. In the above scheme, a first guide roller is provided between the second guide roller and the take-up roller and on the side support plate, and one of the third guide rollers is located between the first guide roller and the fourth guide roller.

[0013] 8. In the above scheme, when the strip support plate is in the first state, the heights of the two third guide rollers are not consistent, and the third guide roller closer to the first conveying track is located above the fourth guide roller.

[0014] 9. In the above scheme, when the strip support plate is in the second state, the two third guide rollers are at the same height.

[0015] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: This invention relates to an anti-sticking paper peeling device. A stop plate is located inside the interval area and perpendicular to the first conveying track. This stop plate is rotatably connected to a first support. A transmission mechanism is provided between the output shaft of a first servo motor and the stop plate. A fourth guide roller is located between the second guide roller and the unwind roller. A rewind roller is located on the side of the fourth guide roller opposite to the first conveying track. A strip-shaped support plate is rotatably mounted on a third support relative to one side of the side support plate. A third guide roller is mounted on each side of the fourth guide roller on the strip-shaped support plate. A third servo motor is located on the side of the third support opposite to the side support plate. The strip-shaped support plate has two working states. The adhesive tape and release paper are adhered between the workpiece and the second guide roller, increasing the contact area with the release paper. Then, by controlling the strip support plate to switch from the first state to the second state, the adhesive tape with release paper adhered to the outer wall of the second guide roller moves backward. The adhesive tape drives the release paper to move relative to the workpiece, separating them and facilitating the peeling of the release paper from the workpiece. Next, the first servo motor drives the abutment plate to rotate and lose its obstruction effect on the workpiece. As the workpiece continues to move on the first and second conveyor tracks, the release paper is completely separated from the workpiece, greatly reducing the probability of release paper peeling failure and improving the overall reliability of the device.

Detailed Implementation

[0018] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0019] Example 1: An anti-sticking paper peeling device for peeling release paper off a workpiece 100, comprising: a first base frame 701 with a first conveying track 1 mounted on top, and a second base frame 702 with a second conveying track 3 mounted on top, wherein an interval area is provided between the first base frame 701 and the second base frame 702, and the size of the workpiece 100 is larger than the width of the interval area, so that the workpiece 100 can be transported between the first conveying track 1 and the second conveying track 3; A first bracket 202 with a first servo motor 203 is installed at one end of the first base frame 701 near the second base frame 702. A support plate 204 is provided inside the interval area and perpendicular to the first conveying track 1. The support plate 204 is rotatably connected to the first bracket 202. A transmission mechanism is provided between the output shaft of the first servo motor 203 and the support plate 204. A side support plate 603 with a third bracket 614 is installed between the first base frame 701 and the second base frame 702. A take-up roller 606, a second guide roller 609 and an unwind roller 611 are rotatably installed on the side support plate 603. The second guide roller 609 is located inside the interval area. The take-up roller 606 is located on the side of the second guide roller 609 opposite to the first conveying track 1. The take-up roller 606 rotates to drive the adhesive tape 607 on the outer wall of the second guide roller 609 to move forward. The workpiece is transported on the first conveyor track. When the workpiece moves to the interval area, one end of the workpiece contacts the back plate. The air rod is activated, and the limit slider moves in the limit groove through the second bracket, thereby driving the side support plate to move up. This makes the adhesive tape on the second guide roller contact the release paper at the bottom of the workpiece. The second servo motor can drive the take-up roller to rotate, thereby driving the adhesive tape to move on the take-up roller, the first guide roller, the second guide roller, the third guide roller, the fourth guide roller, and the unwind roller. A fourth guide roller 615 is disposed between the second guide roller 609 and the unwind roller 611. The take-up roller 606 is located on the side of the fourth guide roller 615 opposite to the first conveying track 1. A strip support plate 612 is rotatably mounted on the third bracket 614 relative to one side of the side support plate 603. A third guide roller 610 is respectively mounted on the strip support plate 612 on both sides of the fourth guide roller 615. A third servo motor 613 is disposed on the side of the third bracket 614 opposite to the side support plate 603. The strip support plate 612 has two working states. When the strip support plate 612 switches from the first state to the second state, the adhesive tape 607 on the outer wall of the second guide roller 609 moves backward. When the adhesive tape separates the release paper from the workpiece, the third servo motor controls the strip support plate to switch from the first state to the second state, changing the position and height of the fourth guide roller. This causes the adhesive tape with the release paper attached to the outer wall of the second guide roller to move backward. The adhesive tape pulls the release paper away from the workpiece, causing the release paper at the tear-off point on the bottom end face of the workpiece to separate from the workpiece, which is beneficial for peeling the release paper off the workpiece.

[0020] The aforementioned transmission mechanism includes: a first support shaft 205 and a second support shaft 206 rotatably mounted on the first bracket 202. A first gear 201 is fixedly mounted on the upper end of the second support shaft 206, and its lower end is fixedly connected to the output shaft of the first servo motor 203. The lower end of the first support shaft 205 is fixedly connected to the abutment plate 204, and a second gear 208 that meshes with the first gear 201 is fixedly mounted on the upper end of the first support shaft 205. The first servo motor drives the bottom plate to rotate 90° through the meshing of the first and second gears, which allows the workpiece to continue moving. As the workpiece continues to move, the adhesive tape can separate the release paper from the workpiece, and the workpiece after the release paper is separated will continue to be transferred to the second conveyor track.

[0021] A torsion spring 207 is fitted on the circumferential outer wall of the first support shaft 205 between the second gear 208 and the first gear 202.

[0022] A gas spring 605 is vertically installed on one side of the aforementioned side support plate 603, and the movable end of the gas spring 605 is fixedly connected to the side support plate 603.

[0023] The aforementioned air spring 605 is fixedly connected to the side support plate 603 by a second bracket 604.

[0024] Both the first base frame 701 and the second base frame 702 have a limiting groove 601 with a slider 602 internally slidably connected in the vertical direction, and the second bracket 604 is fixedly connected to the slider 602.

[0025] The aforementioned gas spring 506 is fixedly installed on the top of a base plate 4.

[0026] A first guide roller 608 is provided between the second guide roller 609 and the take-up roller 606 and on the side support plate 603, and one of the third guide rollers 610 is located between the first guide roller 608 and the fourth guide roller 615.

[0027] When the strip support plate 612 is in the first state, the heights of the two third guide rollers 610 are not consistent, and the third guide roller 610 closer to the first conveying track 1 is located above the fourth guide roller 615.

[0028] When the strip support plate 612 is in the second state, the two third guide rollers 610 are at the same height.

[0029] A second servo motor 5 for driving the take-up roller 606 to rotate is provided on the outer wall of the aforementioned side support plate 603.

[0030] Example 2: An anti-sticking paper peeling device for peeling release paper off a workpiece 100, comprising: a first base frame 701 with a first conveying track 1 mounted on top, and a second base frame 702 with a second conveying track 3 mounted on top, wherein an interval area is provided between the first base frame 701 and the second base frame 702, and the size of the workpiece 100 is larger than the width of the interval area, so that the workpiece 100 can be transported between the first conveying track 1 and the second conveying track 3; A first bracket 202 with a first servo motor 203 is installed at one end of the first base frame 701 near the second base frame 702. A support plate 204 is provided inside the interval area and perpendicular to the first conveying track 1. The support plate 204 is rotatably connected to the first bracket 202. A transmission mechanism is provided between the output shaft of the first servo motor 203 and the support plate 204. A side support plate 603 with a third bracket 614 is installed between the first base frame 701 and the second base frame 702. A take-up roller 606, a second guide roller 609 and an unwind roller 611 are rotatably installed on the side support plate 603. The second guide roller 609 is located inside the interval area. The take-up roller 606 is located on the side of the second guide roller 609 opposite to the first conveying track 1. The take-up roller 606 rotates to drive the adhesive tape 607 on the outer wall of the second guide roller 609 to move forward. The adhesive tape and release paper are pasted between the workpiece and the second guide roller, increasing the contact area with the release paper. Then, by controlling the strip support plate to switch from the first state to the second state, the adhesive tape with release paper pasted on the outer wall of the second guide roller moves backward. The adhesive tape drives the release paper to move relative to the workpiece to separate it, which is beneficial to peel the release paper off the workpiece. A fourth guide roller 615 is disposed between the second guide roller 609 and the unwind roller 611. The take-up roller 606 is located on the side of the fourth guide roller 615 opposite to the first conveying track 1. A strip support plate 612 is rotatably mounted on the third bracket 614 relative to one side of the side support plate 603. A third guide roller 610 is respectively mounted on the strip support plate 612 on both sides of the fourth guide roller 615. A third servo motor 613 is disposed on the side of the third bracket 614 opposite to the side support plate 603. The strip support plate 612 has two working states. When the strip support plate 612 switches from the first state to the second state, the adhesive tape 607 on the outer wall of the second guide roller 609 moves backward. Next, the first servo motor is controlled to drive the platen to rotate and lose its obstruction effect on the workpiece. As the workpiece continues to move on the first and second conveying tracks, the release paper is completely separated from the workpiece, which greatly reduces the probability of release paper peeling failure and improves the overall reliability of the device.

[0031] The aforementioned transmission mechanism includes: a first support shaft 205 and a second support shaft 206 rotatably mounted on the first bracket 202. A first gear 201 is fixedly mounted on the upper end of the second support shaft 206, and its lower end is fixedly connected to the output shaft of the first servo motor 203. The lower end of the first support shaft 205 is fixedly connected to the abutment plate 204, and a second gear 208 that meshes with the first gear 201 is fixedly mounted on the upper end of the first support shaft 205.

[0032] A torsion spring 207 is fitted on the circumferential outer wall of the first support shaft 205 between the second gear 208 and the first gear 202.

[0033] A gas spring 605 is vertically installed on one side of the aforementioned side support plate 603, and the movable end of the gas spring 605 is fixedly connected to the side support plate 603.

[0034] The aforementioned air spring 605 is fixedly connected to the side support plate 603 by a second bracket 604.

[0035] Both the first base frame 701 and the second base frame 702 have a limiting groove 601 with a slider 602 internally slidably connected in the vertical direction, and the second bracket 604 is fixedly connected to the slider 602.

[0036] The aforementioned gas spring 506 is fixedly installed on the top of a base plate 4.

[0037] A first guide roller 608 is provided between the second guide roller 609 and the take-up roller 606 and on the side support plate 603, and one of the third guide rollers 610 is located between the first guide roller 608 and the fourth guide roller 615.

[0038] The aforementioned fourth guide roller 615 is fixedly connected to the strip support plate 612.

[0039] The aforementioned fourth guide roller 615 is installed in the middle of the aforementioned strip support plate 612.

[0040] The working principle is as follows: In use, the workpiece is transported on the first conveyor track. When the workpiece moves to the interval area, one end of the workpiece contacts the back plate. The air rod is activated, and the second bracket drives the limit slider to move in the limit groove, thereby driving the side support plate to move up. This makes the adhesive tape on the second guide roller contact the release paper at the bottom of the workpiece. The second servo motor can drive the take-up roller to rotate, thereby driving the adhesive tape to move on the take-up roller, the first guide roller, the second guide roller, the third guide roller, the fourth guide roller, and the unwind roller. When the adhesive tape separates the release paper from the workpiece, the third servo motor controls the strip support plate to switch from the first state to the second state, changing the position and height of the fourth guide roller. This causes the adhesive tape with the release paper attached to the outer wall of the second guide roller to move backward. The adhesive tape drives the release paper away from the workpiece, causing the release paper at the tear opening at the bottom end of the workpiece to separate from the workpiece, which is beneficial for peeling the release paper off the workpiece. The first servo motor drives the bottom plate to rotate 90° through the meshing of the first and second gears, which allows the workpiece to continue moving. As the workpiece continues to move, the adhesive tape can separate the release paper from the workpiece, and the workpiece after the release paper is separated will continue to be transferred to the second conveyor track.

[0041] When using the above-mentioned anti-sticking paper peeling device, the adhesive tape and release paper are adhered between the workpiece and the second guide roller, increasing the contact area with the release paper. Then, by controlling the strip support plate to switch from the first state to the second state, the adhesive tape with release paper adhered to the outer wall of the second guide roller moves backward. The adhesive tape drives the release paper to move relative to the workpiece for separation, which is beneficial to peeling the release paper off the workpiece. Then, the first servo motor drives the abutment plate to rotate and lose its obstruction effect on the workpiece. As the workpiece continues to move on the first conveying track and the second conveying track, the release paper is completely separated from the workpiece, which greatly reduces the probability of release paper peeling failure and improves the overall reliability of the device.
