Description

Technical Field

[0001] This application relates to the technical field of silicone pad production, and in particular to a release tape application device. Background Technology

[0002] The manufactured silicone pads are cut into silicone pad products of the same size, and then users take out the silicone pads from the silicone pad products as needed.

[0003] refer to Figure 1 The silicone pad product 91 is adhesive. To prevent it from losing its adhesiveness due to prolonged exposure to air, a release film 92 is manually attached to one side of the silicone pad. The cross-section of the release film is larger than that of the silicone pad product 91. Release tape 93 is attached to the other side of the silicone pad, and one of the two adjacent release tapes 93 will overlap the other release tape 93.

[0004] To ensure the stickiness of the remaining silicone pads after removal, the amount of release tape 93 will be relatively large, resulting in a large number of manual application of release tape 93. Since the silicone pad products 91 are produced in large quantities, each silicone pad product 91 has a large amount of release tape 93. Over time, operators will become fatigued, and the efficiency of applying release tape 93 will decrease. Summary of the Invention

[0005] To improve the bonding efficiency of release tape, this application provides a release tape bonding device.

[0006] This application provides a release tape application device, which adopts the following technical solution:

[0007] A release tape application device includes a worktable, a movable frame, a drive unit, a tape placement mechanism, a tape pulling mechanism, a tape pressing mechanism, and a cutting mechanism. The movable frame is slidably mounted on the worktable via the drive unit. The tape placement mechanism, the tape pulling mechanism, and the tape pressing mechanism are all mounted on the movable frame. The cutting mechanism is mounted on the worktable.

[0008] By adopting the above technical solution, the release tape roll is first placed on the tape placement mechanism; then, the worktable with the release film is moved; the drive unit is activated, which moves the moving frame towards the adjustment mechanism; then, the tape pulling mechanism pulls out the tape located on the tape placement mechanism; next, the tape pressing mechanism sticks the release tape to the side of the silicone pad product away from the release film; finally, the cutting mechanism cuts the release tape. The release tape pasting equipment provided in this application can reduce the manual operation of pasting release tape, thereby improving efficiency.

[0009] Optionally, the tape placement mechanism includes a first motor, a placement shaft, a first limiting block, a locking block, a second limiting block, and a connecting bolt. The placement shaft is rotatably mounted on the movable frame. The first motor is mounted on the movable frame and its output shaft is connected to the placement shaft. The first limiting block is mounted on the placement shaft. The locking block is mounted on the placement shaft. The second limiting block has a locking groove for engaging with the locking block. The connecting bolt passes through the second limiting block and is threadedly connected to the placement shaft.

[0010] By adopting the above technical solution, the release tape roll is first placed on the placement shaft, with one side of the release tape roll abutting against the first limiting block; then the slot on the second limiting block engages with the locking block, with the second limiting block abutting against the placement shaft and the side of the release tape roll away from the first limiting block; finally, the connecting bolt is threaded through the second limiting block and connected to the placement shaft, thereby fixing the release tape roll on the placement shaft; the first motor is started, and the output shaft of the first motor drives the placement shaft to rotate, which in turn drives the release tape roll to rotate actively.

[0011] Optionally, two tape pulling mechanisms are provided. Each tape pulling mechanism includes a first cylinder, a first adjusting block, a second adjusting block, a third adjusting block, a first bidirectional cylinder, a clamping and pulling block, and a first adjusting assembly. The cylinder body of the first cylinder is mounted on the movable frame, and the first adjusting block is mounted on the piston rod of the first cylinder. The second adjusting block is slidably mounted on the first adjusting block via the first adjusting assembly. The third adjusting block is mounted on the second adjusting block. The first bidirectional cylinder is mounted on the third adjusting block, and the clamping and pulling block is provided on both piston rods of the first bidirectional cylinder.

[0012] By adopting the above technical solution, the second adjusting blocks in both tape pulling mechanisms are first positioned at the end of the moving frame near the tape placement mechanism, with one second adjusting block located between the other second adjusting block and the tape placement mechanism. The first bidirectional cylinder on the second adjusting block furthest from the tape placement mechanism is activated. This cylinder drives two clamping pulling blocks to move in opposite directions, causing them to clamp the release tape. Then, the first adjusting component connected to this second adjusting block is activated. This component moves the second adjusting block, which in turn moves the third adjusting block. The two clamping pulling blocks on the third adjusting block then pull the release tape. As the release tape is pulled by these two clamping pulling blocks, it passes through the two clamping pulling blocks on the other second adjusting block. After the second adjusting block furthest from the tape placement mechanism has pulled the release tape a certain distance through the two clamping pulling blocks, the first bidirectional cylinder on the other second adjusting block is activated, causing the two clamping pulling blocks on that other second adjusting block to also clamp the release tape. After the release tape is clamped by the clamping and pulling blocks on the two second adjusting blocks, the release tape is adhered to the silicone pad product by the tape adhesion and pressing mechanism and then cut by the cutting mechanism. Then, the first cylinder corresponding to the second adjusting block that was initially furthest from the tape placement mechanism is activated, causing the piston rod of the first cylinder to move the first adjusting block. The first adjusting block then moves the second adjusting block towards the moving frame, so that the two first adjusting blocks in the two tape pulling mechanisms are at a certain distance from their initial positions. Then, the first adjusting component corresponding to the second adjusting block that was initially furthest from the tape placement mechanism is activated, so that the second adjusting block that was initially furthest from the tape placement mechanism is now positioned between the second adjusting block that was initially closest to the tape placement mechanism and the tape placement mechanism. Finally, the first cylinder corresponding to the second adjusting block that was initially furthest from the tape placement mechanism is activated again, so that the distance between the two first adjusting blocks in the two tape pulling mechanisms is restored to its initial level. Moreover, the second adjusting block that was initially close to the tape placement mechanism is now furthest from the tape placement mechanism, and the second adjusting block that was initially furthest from the tape placement mechanism is now closer to the tape placement mechanism. Finally, the above actions of pulling the release tape are repeated.

[0013] Optionally, a second adjusting component is provided on the second adjusting block, and the third adjusting block is rotatably mounted on the second adjusting block via the second adjusting component; a separation mechanism is provided on the worktable, the separation mechanism including a second cylinder, a fourth adjusting block, a second bidirectional cylinder, and a separation clamping block, the cylinder body of the second cylinder is mounted on the movable frame, the fourth adjusting block is mounted on the piston rod of the second cylinder; the second bidirectional cylinder is mounted on the fourth adjusting block, and the separation clamping block is provided on both piston rods of the second bidirectional cylinder.

[0014] By adopting the above technical solution, when the cutting blade finishes cutting the release tape, residual release tape will remain between the two clamping blocks in the tape pulling mechanism on the side away from the placement axis. First, the second adjusting component is activated, which drives the third adjusting block to rotate, making the residual release tape vertically positioned. Then, the second cylinder is activated, and its piston rod drives the fourth adjusting block towards the residual release tape, placing it between the two separating clamping blocks. Next, the second bidirectional cylinder is activated, and its piston rod drives the two separating clamping blocks to move towards each other, clamping the residual release tape. Then, the second cylinder is activated again, causing the fourth adjusting block to move towards the moving frame, pulling the residual release tape away from the clamping blocks. Finally, the second adjusting component is activated again, returning the third adjusting block to its initial position.

[0015] Optionally, the tape bonding mechanism includes a support block, an electric push rod, a lifting block, a moving block, a fixed shaft, a first pressure roller, a second pressure roller, and a third adjusting component. The support block is mounted on the moving frame, the electric push rod is mounted on the support block, the lifting block is mounted on the piston rod of the electric push rod, and the moving block is slidably mounted on the lifting block via the third adjusting component. The fixed shaft is mounted on the moving block, and both the first and second pressure rollers are mounted on the fixed shaft, with the first pressure roller abutting against the second pressure roller. The cross-section of the first pressure roller is larger than the cross-section of the second pressure roller.

[0016] By adopting the above technical solution, after both tape pulling mechanisms clamp the release tape, the electric push rod is activated. The electric push rod drives the lifting block to move closer to the worktable, causing the first pressure roller on the moving block to contact the release tape. Then, the electric push rod continues to drive the lifting block closer to the worktable. Simultaneously, one of the tape pulling mechanisms drives the release tape to move, keeping the release tape taut. When the release tape contacts the silicone pad, the first pressure roller contacts a portion of the release tape adhered to the silicone pad product, and the second pressure roller contacts the release tape adhered to the adjacent release tape. Then, the third adjustment component is activated. The third adjustment component drives the moving block to move on the lifting block, and the fixed shaft on the moving block drives the first and second pressure rollers to move, causing the release tape to adhere to the silicone pad product.

[0017] Optionally, the cutting mechanism includes a third cylinder, a fourth cylinder, a first moving block, a second moving block, and a cutting blade. The cylinder body of the third cylinder is disposed on the worktable, and the first moving block is disposed on the piston rod of the third cylinder. The cylinder body of the fourth cylinder is disposed on the first moving block, and the second moving block is disposed on the piston rod of the fourth cylinder. The cutting blade is disposed on the second moving block.

[0018] By adopting the above technical solution, the third cylinder is started, and the piston rod of the third cylinder drives the first moving block to move. The first moving block causes the position of the fourth cylinder to change, so that the cutting blade can be located on both sides of the corresponding silicone pad. Then the fourth cylinder is started, and the piston rod of the fourth cylinder drives the second moving block to move. The second moving block will then drive the cutting blade to move, and the moving cutting blade will cut the release tape.

[0019] Optionally, the workbench is provided with an adjustment mechanism, which includes a second motor and an adjustment block. The second motor is disposed on the workbench, and the adjustment block is disposed on the output shaft of the second motor.

[0020] By adopting the above technical solution, the release film of the silicone pad product is placed on the adjustment block, and then the second motor is started. The output shaft of the second motor drives the adjustment block to rotate, and the adjustment block drives the silicone pad to rotate, thereby adjusting the position of the silicone pad. The set adjustment mechanism can adjust the position of the silicone pad, so that the tape adhesion mechanism can better stick the release tape to the silicone pad product.

[0021] Optionally, the workbench is provided with a stabilizing mechanism, which includes a fifth cylinder, a movable block, a sixth cylinder, a connecting block, a third bidirectional cylinder, and stabilizing blocks. The cylinder body of the fifth cylinder is disposed on the workbench, and the movable block is disposed on the piston rod of the fifth cylinder. The cylinder body of the sixth cylinder is disposed on the movable block, and the connecting block is disposed on the piston rod of the sixth cylinder. The third bidirectional cylinder is disposed on the connecting block, and the stabilizing blocks are disposed on both piston rods of the third bidirectional cylinder.

[0022] By adopting the above technical solution, the third bidirectional cylinder is first activated, and its two piston rods drive the two stabilizing blocks to move towards or away from each other. Then, the fifth cylinder is activated, and its piston rod drives the movable block to move on the worktable. The sixth cylinder on the movable block drives the connecting block to move, so that the two stabilizing blocks correspond to the release film on both sides of the length direction of the silicone pad product. Then, the sixth cylinder is activated, and its piston rod drives the connecting block to move closer to the worktable. The third bidirectional cylinder on the connecting block then drives the two stabilizing blocks to move closer to the worktable, so that both stabilizing blocks abut against the release film on the silicone pad. The stabilizing mechanism can improve the stability of the silicone pad product on the worktable and reduce the phenomenon of the silicone pad product moving on the worktable when applying release tape.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The release tape application device provided in this application can reduce the manual application of release tape, thereby improving efficiency;

[0025] 2. The stabilizing mechanism improves the stability of the silicone pad on the workbench and reduces movement of the silicone pad on the workbench when applying release tape. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 2-10 This application will be described in further detail.

[0038] This application discloses a release tape application device.

[0039] refer to Figure 2 A release tape application device includes a workbench 11, on which an adjustment mechanism 7 and a stabilizing mechanism 8 are provided; a movable frame 12 is slidably mounted on the workbench 11 via a drive component 13, on which a tape placement mechanism 2, a tape pulling mechanism 3 and a tape pressing mechanism 5 are provided; and a cutting mechanism 6 is provided on the workbench 11.

[0040] First, place the release tape roll on the tape placement mechanism 2; then place the silicone pad with the release film on the adjustment mechanism 7, and then use the stabilizing mechanism 8 to press against the release film of the silicone pad product; start the drive component 13, which drives the moving frame 12 to move closer to the adjustment mechanism 7, and then use the tape pulling mechanism 3 to pull out the tape located on the tape placement mechanism 2. Next, the tape pressing mechanism 5 sticks the release tape to the side of the silicone pad product away from the release film, and finally, the cutting mechanism 6 cuts the release tape.

[0041] Reference 2 and Figure 3 The adjustment mechanism 7 includes a second motor 71 fixedly connected to the worktable 11. An adjustment block 72 is rotatably connected to the output shaft of the second motor 71. The adjustment block 72 is cylindrical, and the end face of the adjustment block 72 away from the second motor 71 is on the same horizontal plane as the operating surface of the worktable 11.

[0042] Place the release film of the silicone pad product on the adjustment block 72, and then start the second motor 71. The output shaft of the second motor 71 drives the adjustment block 72 to rotate, which in turn drives the silicone pad to rotate, thereby adjusting the position of the silicone pad.

[0043] refer to Figure 2 and Figure 3 The stabilizing mechanism 8 includes a fifth cylinder 81 mounted on the workbench 11. The cylinder body of the fifth cylinder 81 is fixedly connected to the workbench 11. A movable block 82 is connected to the piston rod of the fifth cylinder 81. A connecting block 84 is slidably connected to the movable block 82. A third bidirectional cylinder 85 is mounted on the connecting block 84. The cylinder body of the third bidirectional cylinder 85 is fixed to the connecting block 84. Stabilizing blocks 86 are mounted on both piston rods of the third bidirectional cylinder 85. A sixth cylinder 83 is mounted on the movable block 82. The cylinder body of the sixth cylinder 83 is fixed to the movable block 82. The piston rod of the sixth cylinder 83 is connected to the connecting block 84.

[0044] First, the third bidirectional cylinder 85 is activated. The two piston rods of the third bidirectional cylinder 85 drive the two stabilizing blocks 86 to move towards or away from each other. Then, the fifth cylinder 81 is activated. The piston rod of the fifth cylinder 81 drives the movable block 82 to move on the worktable 11. The sixth cylinder 83 on the movable block 82 drives the connecting block 84 to move, so that the two stabilizing blocks 86 correspond to the release film on both sides of the length direction in the silicone pad product. Then, the sixth cylinder 83 is activated. The piston rod of the sixth cylinder 83 drives the connecting block 84 to move towards the worktable 11. The third bidirectional cylinder 85 on the connecting block 84 will then drive the two stabilizing blocks 86 to move towards the worktable 11, so that both stabilizing blocks 86 abut against the release film on the silicone pad.

[0045] refer to Figure 2 and Figure 4 The driving component 13 is a driving cylinder. The cylinder body of the driving cylinder is fixed on the worktable 11, and the piston rod of the driving cylinder is connected to the moving frame 12.

[0046] refer to Figure 4 and Figure 5The tape placement mechanism 2 includes a placement shaft 22 rotatably connected to a movable frame 12; a first motor 21 is fixedly connected to the movable frame 12, and the output shaft of the first motor 21 is connected to the placement shaft 22. A first limiting block 23 is fixedly connected to the placement shaft 22, and a locking block 24 is fixedly connected to the end of the placement shaft 22 away from the movable frame 12; a second limiting block 25 is provided at the end of the placement shaft 22 away from the movable frame 12, which abuts against the placement shaft 22; a locking groove 251 is provided on the second limiting block 25 to engage with the locking block 24; and a connecting bolt 26 is provided on the second limiting block 25 to be threadedly connected to the placement shaft 22.

[0047] First, place the release tape roll on the placement shaft 22, with one side of the release tape roll abutting against the first limiting block 23. Then, engage the slot 251 on the second limiting block 25 with the locking block 24, with the second limiting block 25 abutting against the placement shaft 22 and the side of the release tape roll away from the first limiting block 23. Finally, thread the connecting bolt 26 through the second limiting block 25 and onto the placement shaft 22 to fix the release tape roll onto the placement shaft 22. Then, start the first motor 21. The output shaft of the first motor 21 drives the placement shaft 22 to rotate, which in turn drives the release tape roll to rotate, allowing the release tape to unwind from the release tape roll.

[0048] refer to Figure 4 , Figure 6 and Figure 7 Two tape pulling mechanisms 3 are provided. Each tape pulling mechanism 3 includes a first cylinder 31 fixedly connected to the movable frame 12. A first adjusting block 32 is connected to the piston rod of the first cylinder 31. A first sliding groove 321 is provided on the first adjusting block 32. A second adjusting block 33 is slidably connected in the first sliding groove 321. The two second adjusting blocks 33 are located between the two first adjusting blocks 32. A first adjusting component 37 connected to the second adjusting block 33 is provided on the first adjusting block 32. The first adjusting component 37 includes a first screw 372 rotatably connected in the first sliding groove 321. The first screw 372 passes through the second adjusting block 33 and is threadedly connected to the second adjusting block 33. A third motor 371 is fixedly connected to the first adjusting block 32. The output shaft of the third motor 371 is connected to one end of the first screw 372.

[0049] When the third motor 371 is started, its output shaft drives the first screw 372 to rotate, which in turn causes the second adjusting block 33 to slide within the first groove 321 of the first adjusting block 32. When the first cylinder 31 is started, its piston rod drives the first adjusting block 32 to move, which in turn changes the position of the second adjusting block 33.

[0050] Figure 6 and Figure 7A second adjusting component 38 is provided at the end of the second adjusting block 33 away from the first adjusting block 32. The second adjusting component 38 includes a fourth motor 381 fixedly connected to the second adjusting block 33, and an adjusting shaft 382 is connected to the output shaft of the fourth motor 381. A third adjusting block 34 is fixedly connected to the adjusting shaft 382, ​​and the two third adjusting blocks 34 in the two tape pulling mechanisms 3 are located between the two second adjusting blocks 33.

[0051] When the fourth motor 381 is started, the output shaft of the fourth motor 381 drives the adjusting shaft 382 to rotate, and the adjusting shaft 382 will drive the third adjusting block 34 to rotate.

[0052] Figure 6 and Figure 7 The third adjusting block 34 is provided with a first bidirectional cylinder 35. The cylinder body of the first bidirectional cylinder 35 is fixedly connected to the third adjusting block 34. Each of the two piston rods of the first bidirectional cylinder 35 is connected to a clamping and pulling block 36. The clamping and pulling blocks 36 on the first bidirectional cylinder 35 in the two tape pulling mechanisms 3 are located between the two third adjusting blocks 34.

[0053] When the first bidirectional cylinder 35 is activated, the two piston rods of the first bidirectional cylinder 35 will drive the two clamping and pulling blocks 36 to move in opposite directions or away from each other.

[0054] First, position the second adjusting block 33 in both tape pulling mechanisms 3 at the end of the moving frame 12 closest to the placement shaft 22. Then, name the tape pulling mechanism 3 where the second adjusting block 33 is initially furthest from the placement shaft 22 as the first tape pulling mechanism 3, and name the tape pulling mechanism 3 where the second adjusting block 33 is initially closest to the placement shaft 22 as the second tape pulling mechanism 3.

[0055] The first bidirectional cylinder 35 in the first tape pulling mechanism 3 is activated, which drives the two clamping and pulling blocks 36 to move in opposite directions, causing the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 to clamp the release tape. Then, the third motor 371 in the first tape pulling mechanism 3 is activated, and the second adjusting block 33 in the first tape pulling mechanism 3 drives the third adjusting block 34 to move. The two clamping and pulling blocks 36 on the third adjusting block 34 will pull the release tape to move, and the release tape will be unwound from the release tape roll. When the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 pull the release tape to move, the release tape will pass through the two clamping and pulling blocks 36 in the second tape pulling mechanism 3. When the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 pull the release tape a certain distance, the first bidirectional cylinder 35 in the second tape pulling mechanism 3 is activated, so that the two clamping and pulling blocks 36 in the second tape pulling mechanism 3 also clamp the release tape.

[0056] Then, the tape pressing mechanism 5 is used to stick the release tape between the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 and the two clamping and pulling blocks 36 in the second tape pulling mechanism 3 onto the silicone pad product. Next, the cutting mechanism 6 is used to cut off the release tape on the side of the two clamping and pulling blocks 36 in the second tape pulling mechanism 3 that is close to the second adjusting block 33 in the first tape pulling mechanism 3. Then, the release tape on the side of the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 that is close to the second adjusting block 33 in the second tape pulling mechanism 3 is also cut off.

[0057] Then, the first cylinder 31 in the first tape pulling mechanism 3 is activated, causing the piston rod of the first cylinder 31 to drive the first adjusting block 32 to move. The first adjusting block 32 drives the second adjusting block 33 to move towards the moving frame 12. In this way, the first adjusting block 32 in the first tape pulling mechanism 3 and the first adjusting block 32 in the second tape pulling mechanism 3 are displaced relative to the initial horizontal direction. Then, the third motor 371 in the first tape pulling mechanism 3 is activated, causing the second adjusting block 33 in the first tape pulling mechanism 3 to move between the second adjusting block 33 in the second tape pulling mechanism 3 and the placement shaft 22. Then, the first cylinder 31 in the first tape pulling mechanism 3 is activated again, causing the first adjusting block 32 to move away from the moving frame 12, so that the release tape can be located between the two clamping pulling blocks 36 in the first tape pulling mechanism 3.

[0058] Then, the two clamping and pulling blocks 36 in the second tape pulling mechanism 3 pull the release tape. After the release tape is pulled out a certain distance, the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 clamp the release tape.

[0059] Then, the tape pressing mechanism 5 attaches the release tape between the two clamping and pulling blocks 36 in the second tape pulling mechanism 3 and the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 to the silicone pad product. Next, the cutting mechanism 6 cuts off the release tape on the side of the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 that is close to the second adjusting block 33 in the second tape pulling mechanism 3. Then, the release tape on the side of the two clamping and pulling blocks 36 in the second tape pulling mechanism 3 that is close to the second adjusting block 33 in the first tape pulling mechanism 3 is also cut off.

[0060] Then, the first cylinder 31 in the second tape pulling mechanism 3 is activated, causing the first adjusting block 32 in the second tape pulling mechanism 3 to move away from the moving frame 12. This causes the first adjusting block 32 in the second tape pulling mechanism 3 to shift relative to the first adjusting block 32 in the first tape pulling mechanism 3 in the initial horizontal direction. Then, the third motor 371 in the second tape pulling mechanism 3 is activated, causing the second adjusting block 33 in the second tape pulling mechanism 3 to move between the second adjusting block 33 in the first tape pulling mechanism 3 and the placement shaft 22. Then, the first cylinder 31 in the second tape pulling mechanism 3 is activated again, causing the first adjusting block 32 to move closer to the moving frame 12, so that the release tape can be positioned between the two clamping pulling blocks 36 in the second tape pulling mechanism 3.

[0061] Reference 4 and Figure 8 The tape pressing mechanism 5 includes a support block 51 fixedly connected to the movable frame 12. An electric push rod 52 is fixedly connected to the support block 51. A lifting block 53 is provided on the piston rod of the electric push rod 52. The lifting block 53 is located between two first adjusting blocks 32 in the two tape pulling mechanisms 3. A second sliding groove 531 is provided on the lifting block 53, and a movable block 54 is slidably connected in the second sliding groove 531. A third adjusting component 58 is provided on the lifting block 53. The third adjusting component 58 includes a second screw 582 rotatably connected in the second sliding groove 531. The second screw 582 passes through the movable block 54 and is threadedly connected to the movable block 54. A fifth motor 581 is fixedly connected to the lifting block 53, and the output shaft of the fifth motor 581 is connected to one end of the second screw 582.

[0062] A fixed shaft 55 is rotatably connected to the movable block 54. A first pressure roller 56 and a second pressure roller 57 are fixedly connected to the fixed shaft 55. The second pressure roller 57 abuts against the first pressure roller 56. The cross-section of the first pressure roller 56 is larger than the cross-section of the second pressure roller 57, and the difference between the radius of the first pressure roller 56 and the radius of the second pressure roller 57 is twice the thickness of the release tape.

[0063] When both clamping and pulling blocks 36 in the first tape pulling mechanism 3 and the two clamping and pulling blocks 36 in the second tape pulling mechanism 3 have clamped the release tape, the electric push rod 52 is activated. The electric push rod 52 drives the lifting block 53 to move towards the worktable 11, so that the first pressure roller 56 on the moving block 54 abuts against the release tape.

[0064] Then the electric actuator 52 continues to drive the lifting block 53 to move closer to the worktable 11. At the same time, the second adjusting block 33 in the tape pulling mechanism 3 on the side away from the placement shaft 22 moves closer to the placement shaft 22, so that the release tape is always in a taut state.

[0065] When the release tape comes into contact with the silicone pad, the first pressure roller 56 comes into contact with a portion of the release tape that is bonded to the silicone pad product, and the second pressure roller 57 comes into contact with the release tape that is bonded to the adjacent release tape.

[0066] Then, the fifth motor 581 is started. The output shaft of the fifth motor 581 drives the second screw 582 to rotate. The second screw 582 drives the moving block 54 to slide in the second slide groove 531 of the lifting block 53. The fixed shaft 55 on the moving block 54 will drive the first pressure roller 56 and the second pressure roller 57 to move, so that the release tape is attached to the silicone pad product.

[0067] refer to Figure 4 and Figure 9 The cutting mechanism 6 includes a third cylinder 61 mounted on the worktable 11. The cylinder body of the third cylinder 61 is fixedly connected to the worktable 11. A first moving block 63 is connected to the piston rod of the third cylinder 61. A fourth cylinder 62 is mounted on the first moving block 63. The cylinder body of the fourth cylinder 62 is fixed to the first moving block 63. A second moving block 64 is connected to the piston rod of the fourth cylinder 62. A cutting blade 65 is fixedly connected to the second moving block 64.

[0068] The third cylinder 61 is activated, and its piston rod drives the first moving block 63 to move. The first moving block 63 causes the position of the fourth cylinder 62 to change, so that the cutting blade 65 can be positioned on both sides of the corresponding silicone pad. Then the fourth cylinder 62 is activated, and its piston rod drives the second moving block 64 to move. The second moving block 64 then moves the cutting blade 65, and the moving cutting blade 65 cuts the release tape.

[0069] refer to Figure 4 and Figure 10 The movable frame 12 is provided with a separation mechanism 4. The separation mechanism 4 includes a second cylinder 41 provided on the movable frame 12. The cylinder body of the second cylinder 41 is fixedly connected to the movable frame 12. A fourth adjusting block 42 is connected to the piston rod of the second cylinder 41. A second bidirectional cylinder 43 is fixedly connected to the fourth adjusting block 42. Separation clamping blocks 44 are connected to both piston rods of the second bidirectional cylinder 43.

[0070] When the cutting blade 65 finishes cutting the release tape, residual release tape will remain between the two clamping blocks 36 in the tape pulling mechanism 3 on the side away from the placement shaft 22. First, start the fourth motor 381. The output shaft of the fourth motor 381 drives the adjusting shaft 382 to rotate, and the adjusting shaft 382 drives the third adjusting block 34 to rotate, so that the residual release tape is set vertically. Then, the second cylinder 41 is activated, and the piston rod of the second cylinder 41 drives the fourth adjusting block 42 to move towards the residual release tape, so that the residual release tape is located between the two separating clamping blocks 44; next, the second bidirectional cylinder 43 is activated, and the piston rod of the second bidirectional cylinder 43 drives the two separating clamping blocks 44 to move towards each other, so that the two separating clamping blocks 44 clamp the residual release tape; then the second cylinder 41 is activated again, so that the fourth adjusting block 42 moves towards the moving frame 12, and the two separating clamping blocks 44 will pull the residual release tape to move, so that the residual release tape leaves the clamping pulling block 36; finally, the fourth motor 381 is activated, so that the third adjusting block 34 returns to its initial position.

[0071] The implementation principle of the release tape pasting device in this application embodiment is as follows: the release film of the silicone pad product is placed on the adjustment block 72, and then the second motor 71 is started, which will drive the silicone pad to rotate.

[0072] Then start the third bidirectional cylinder 85 to adjust the position of the two stabilizing blocks 86; then start the fifth cylinder 81 to move the movable block 82 to the vicinity of the silicone pad; then start the sixth cylinder 83 to move the two stabilizing blocks 86 toward the worktable 11, and make both stabilizing blocks 86 abut against the release film on the silicone pad.

[0073] Initially, the second adjusting blocks 33 in both tape pulling mechanisms 3 are located at the end of the moving frame 12 near the placement shaft 22. Then, the first bidirectional cylinder 35 in the first tape pulling mechanism 3 is activated, which drives the two clamping pulling blocks 36 to move in opposite directions, causing the two clamping pulling blocks 36 in the first tape pulling mechanism 3 to clamp the release tape. Then, the third motor 371 in the first tape pulling mechanism 3 is activated, and the second adjusting block 33 in the first tape pulling mechanism 3 drives the third adjusting block 34 to move. The two clamping pulling blocks 36 on the third adjusting block 34 will then pull the release tape, and the release tape will unwind from the release tape roll. When the two clamping pulling blocks 36 in the first tape pulling mechanism 3 pull the release tape, the release tape will pass through the two clamping pulling blocks 36 in the second tape pulling mechanism 3. When the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 pull the release tape a certain distance, the first bidirectional cylinder 35 in the second tape pulling mechanism 3 is activated, so that the two clamping and pulling blocks 36 in the second tape pulling mechanism 3 also clamp the release tape.

[0074] Then, the electric actuator 52 drives the lifting block 53 to move closer to the worktable 11, causing the first pressure roller 56 on the moving block 54 to contact the release tape. The electric actuator 52 continues to drive the lifting block 53 closer to the worktable 11. At the same time, the second adjusting block 33 in the tape pulling mechanism 3, which is away from the placement shaft 22, moves closer to the placement shaft 22, keeping the release tape taut. In this way, the release tape near the two clamping pulling blocks 36 in the second tape pulling mechanism 3 will first contact one side of the silicone pad. When the first release tape is applied, only the first pressure roller 56 actively contacts the release tape. Then, the fifth motor 581 is started, causing the moving block 54 to move on the lifting block 53. The first pressure roller on the moving block 54 applies the release tape to the silicone pad product. When applying other release tapes, the first pressure roller 56 applies one side of the release tape to the silicone pad product, and the second pressure roller 57 applies the other side of the release tape to the adjacent release tape.

[0075] Then, the fourth cylinder 62 is activated, and the piston rod of the fourth cylinder 62 drives the second moving block 64 to move. The cutting blade 65 on the second moving block 64 will cut the release tape of the silicone pad close to the two clamping and pulling blocks 36 in the second tape pulling mechanism 3. Then, the fourth cylinder 62 is activated again to return the cutting blade 65 to its initial position. Then, the third cylinder 61 is activated, and the first moving block 63 on the third cylinder 61 drives the fourth cylinder 62 to move to the other side of the silicone tape. Then, the fourth cylinder 62 is activated again to make the cutting blade 65 cut the release tape of the silicone pad close to the two clamping and pulling blocks 36 in the first tape pulling mechanism 3.

[0076] After cutting, the release tape remaining between the two clamping blocks 36 in the first tape pulling mechanism 3 is clamped by two separating clamping blocks 44, so that the release tape remaining between the two clamping blocks 36 in the first tape pulling mechanism 3 is separated from the two clamping blocks 36.

[0077] Then the drive cylinder is activated, and the piston rod of the drive cylinder drives the moving frame 12 to move.

[0078] Then, the first cylinder 31 in the first tape pulling mechanism 3 is activated, causing the piston rod of the first cylinder 31 to drive the first adjusting block 32 to move towards the moving frame 12. This causes the first adjusting block 32 in the first tape pulling mechanism 3 to shift relative to the first adjusting block 32 in the second tape pulling mechanism 3 in the initial horizontal direction. Then, the third motor 371 in the first tape pulling mechanism 3 is activated, causing the second adjusting block 33 in the first tape pulling mechanism 3 to move between the second adjusting block 33 in the second tape pulling mechanism 3 and the placement shaft 22. Then, the first cylinder 31 in the first tape pulling mechanism 3 is activated again, causing the first adjusting block 32 to move away from the moving frame 12, so that the release tape can be located between the two clamping pulling blocks 36 in the first tape pulling mechanism 3.

[0079] Then, the two clamping and pulling blocks 36 in the second tape pulling mechanism 3 pull the release tape. After the release tape is pulled out a certain distance, the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 clamp the release tape.

[0080] Then, the tape pressing mechanism 5 attaches the release tape between the two clamping and pulling blocks 36 in the second tape pulling mechanism 3 and the two clamping and pulling blocks 36 in the first tape pulling mechanism 3 to the silicone pad product.

[0081] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
