Description

Technical Field

[0001] This utility model relates to the field of cutting component technology, specifically to a substrate film cutting component for UV-curable tape. Background Technology

[0002] UV-removable pressure-sensitive adhesives, also known as UV-removable adhesives, are a type of pressure-sensitive adhesive whose adhesive strength decreases upon UV light excitation. UV-removable adhesives are characterized by easy application, high initial adhesion, and easy removal after UV re-adhesion. They can be used in semiconductor processing as temporary fixing and protective tapes for wafer dicing. They can also be used for temporary protection of exterior components during manufacturing. Furthermore, they can be used as transport tapes in the production of flexible circuit boards. Their excellent adhesion ensures that flexible circuit boards will not detach during nickel plating and gold plating processes, and their ease of removal after re-adhesion prevents deformation of the flexible circuit board due to excessive adhesive force when removing the protective tape.

[0003] However, in the actual use of a substrate film cutting assembly for a UV-curable tape, the film port is not fixed. During the cutting process, the film port is not completely adsorbed onto the substrate film adsorption plate, which causes the film port to curl upwards during use, making the film prone to falling off and affecting the cutting of the film.

[0022] Please see Figure 1-4This utility model provides a technical solution: a substrate film cutting assembly for UV-curable tape, comprising a device body 1, a third fixing plate 16 symmetrically fixedly connected to one side of the top of the device body 1, a take-up roller 17 snap-fitted to the top of the third fixing plate 16, a mounting frame 10 slidably connected to the top of the device body 1, a screw slide 11 fixedly connected to the inner wall of the mounting frame 10, an electric telescopic rod 12 slidably connected to the bottom of the screw slide 11, a cutting blade 13 fixedly connected to the bottom of the electric telescopic rod 12, a pressure roller 7 mechanism for leveling the substrate film and a lifting mechanism respectively provided on both sides of the mounting frame 10, and a fixing mechanism for clamping the end of the substrate film provided on the other side of the top of the device body 1, the fixing mechanism including a fixed connection to the mounting frame 10.

Figure 2 As shown, the port of the substrate film will be placed inside the fixing frame 2. The fixing frame 2 will appropriately block the port of the substrate film on both sides to prevent it from warping. At the same time, in order to further prevent the side of the port of the substrate film from warping upward, a first adjustment plate 5 is set on the side of the substrate film to prevent the film from being affected by warping.

[0023] Please see Figure 1 This utility model provides a new embodiment in which the lifting mechanism includes a second fixing plate 14 symmetrically fixedly connected to the top of the device body 1. A double-rod pressure roller 25 is fixedly connected to the inner wall of the second fixing plate 14.

Then, the substrate film is inserted below the pressure roller 7 to further fix the substrate film.

[0024] Please see Figure 2 This utility model provides a new embodiment in which the adjustment mechanism includes a first adjustment plate 5 symmetrically slidably connected inside the fixed frame 2, a second adjustment plate 8 symmetrically slidably connected to the outer wall of the pressure roller 7, a third adjustment plate 15 symmetrically slidably connected to the outer wall of the double-rod pressure roller 25, and a driving mechanism for driving the first adjustment plate 5 to slide is provided at the bottom of the first adjustment plate 5.

[0025] Please see Figure 2 This utility model provides a new embodiment, wherein the driving mechanism includes a first bidirectional threaded rod 18 rotatably connected to the inside of the first slide groove 101 via a bearing, a second bidirectional threaded rod 23 rotatably connected to the inside of the second slide groove 102 via a bearing, and a third bidirectional threaded rod 26 rotatably connected to the inside of the third slide groove 103 via a bearing. The outer walls of the first bidirectional threaded rod 18, the second bidirectional threaded rod 23, and the third bidirectional threaded rod 26 are respectively slidably connected to a first adjusting plate 5, a second adjusting plate 8, and a third adjusting plate 15. One end of the first bidirectional threaded rod 18 is provided with a rotating mechanism for driving the first bidirectional threaded rod 18 to rotate.

[0026] Please see Figure 2 This utility model provides a new embodiment, in which the rotating mechanism includes a first synchronous pulley 20 fixedly connected to the outer wall of the first bidirectional threaded rod 18, a second synchronous pulley 21 and a third synchronous pulley 22 fixedly connected at equal intervals to the outer wall of the second bidirectional threaded rod 23, and a fourth synchronous pulley 24 fixedly connected to the outer wall of the third bidirectional threaded rod 26. The first synchronous pulley 20 and the second synchronous pulley 21 are connected by a timing belt, and the third synchronous pulley 22 and the fourth synchronous pulley 24 are connected by a timing belt. A gearbox 9 is fixedly connected to the outer wall of the main body 1 of the device, and a first synchronous pulley 24 is provided inside the gearbox 9. The gearbox 9 is externally fixedly connected to a servo motor 4, which includes a second synchronous wheel 20, a third synchronous wheel 21, a third synchronous wheel 22, and a fourth synchronous wheel 24. The output end of the servo motor 4 is fixedly connected to the first bidirectional threaded rod 18. By setting an adjustment mechanism, the adjustment mechanism can appropriately adjust the distance between the two second adjustment plates 8 and the third adjustment plate 15 according to the width of the substrate film, so as to make contact with the side of the substrate film and prevent the substrate film from shifting during the movement, which would affect the cutting of the substrate film and result in an uneven cut surface, thus affecting the quality of the cut substrate film.

[0027] Working principle: In use, firstly, the take-up roller 17, which is wrapped with UV-curable tape, is inserted into the third fixed plate 16. Then, the servo motor 4 is started. The rotation of the servo motor 4 will cause the first bidirectional threaded rod 18 to rotate. The rotation of the first bidirectional threaded rod 18 will cause the first synchronous pulley 20 to rotate. This will cause the second synchronous pulley 21 to rotate via the synchronous belt. The rotation of the third synchronous pulley 22 will cause the second bidirectional threaded rod 23 to rotate. Simultaneously, the rotation of the second synchronous pulley 21 will cause the third synchronous pulley 22 to rotate. The rotation of the third synchronous pulley 22 will cause the fourth synchronous pulley 24 to rotate via the synchronous belt, thereby causing the first bidirectional threaded rod 18 to rotate. Simultaneous rotation of threaded rod 18, second bidirectional threaded rod 23, and third bidirectional threaded rod 26 causes the first adjusting plate 5, second adjusting plate 8, and third adjusting plate 15 to move towards the center. After adjusting to the width of the substrate film, the servo motor 4 is turned off. Then, the substrate film passes through the double-rod pressure roller 25 and pressure roller 7 in sequence, and the end of the substrate film is placed in the fixed frame 2. Then, the operator rotates the self-locking knob 3. The rotation of the self-locking knob 3 will cause the threaded rod 28 to rotate, and the rotation of the threaded rod 28 will cause the pressure plate 19 to move downward. When the pressure plate 19 moves above the substrate film, the operator stops rotating the self-locking knob 3.

[0028] Then, the operator adjusts the position of the mounting frame 10 appropriately so that the distance between the cutting blade 13 and the inside of the fixed frame 2 is the length of the substrate film to be cut. Then, the operator stops moving the mounting frame 10 and locks the mounting frame 10. Then, the operator starts the electric telescopic rod 12 to move the cutting blade 13 to the surface of the substrate film. Finally, the operator starts the lead screw slide 11 to move the cutting blade 13 and cut the substrate film.
