[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] Please see Figures 1-6 This utility model provides a technical solution: a cutting device for processing OCA optical adhesive, including a worktable 1, and also including;

[0036] Two connecting frames 2 are set on both sides of the workbench 1. Each connecting frame 2 is equipped with a cylinder 3. A cutting frame 4 is set on the output end of the two cylinders 3. A cutter 5 is set on the cutting frame 4.

[0037] Height adjustment component 200 is installed on workbench 1;

[0038] Mounting bracket 6 is mounted on workbench 1 via height adjustment component 200;

[0039] A pair of first mounting rods 7 are slidably connected to the mounting frame 6. One end of the pair of first mounting rods 7 is located above the mounting frame 6 and a first connecting rod 10 is provided. The other end of the pair of first mounting rods 7 is located below the mounting frame 6 and a pressure plate 8 is provided. Springs 9 are sleeved on the outer walls of the two first mounting rods 7. The two ends of the springs 9 abut against the mounting frame 6 and the pressure plate 8 respectively.

[0040] The height adjustment component 200 is used to adjust the height of the mounting bracket 6;

[0041] Fixture 100 is mounted on mounting bracket 6 and is used to fix the position of pressure plate 8.

[0042] The fastener 100 also includes two second connecting plates 21 disposed on the pressure plate 8, and each of the two second connecting plates 21 is provided with an insertion hole 22;

[0043] The mounting bracket 6 also has clearance holes 20 for two second connecting plates 21 to pass through. Two mounting tubes 101 are provided on the top of the mounting bracket 6, and sliding rods 102 are slidably connected to the two mounting tubes 101. One end of the sliding rod 102 is provided with an insert plate 105 for passing through the insertion hole 22, and the other end of the sliding rod 102 is provided with a connecting piece 103. A tension spring 104 is sleeved on the outer wall of the sliding rod 102, with both ends of the tension spring 104 respectively located on the mounting tube 101 and the connecting piece 103. When cleaning the workbench 1, the operator should first store and fix the pressure plate 8, which can be achieved by pulling... The connecting piece 103 is used to drive the sliding rod 102 to slide on the mounting tube 101. The sliding rod 102 then pushes the insert plate 105 to move towards the mounting tube 101. At this time, the tension spring 104 is stretched. The operator can then pull the first connecting rod 10 to move the pressure plate 8 to the appropriate position. Once in place, the connecting piece 103 is released, and the elastic force of the tension spring 104 will reset the sliding rod 102. The sliding rod 102 then drives the insert plate 105 to move, so that the insert plate 105 passes through the insertion hole 22. In this way, the pressure plate 8 is stored and fixed, which facilitates cleaning of the workbench 1.

[0044] The outer wall of the insert plate 105 is provided with a first arc-shaped groove 106, and the top of the second connecting plate 21 is provided with a second arc-shaped groove 23 that cooperates with the first arc-shaped groove 106. The mounting tube 101 is provided with a rectangular guide hole 107, and the sliding rod 102 is provided with a bolt 108 by thread. The bolt 108 has the freedom to move along the length of the rectangular guide hole 107. When the second connecting plate 21 moves upward, the cooperation of the first arc-shaped groove 106 and the second arc-shaped groove 23 allows the insert plate 105 to slide smoothly on the second connecting plate 21. At the same time, the bolt 108 can move within the rectangular guide hole 107 to further fix the position of the insert plate 105 and prevent the pressure plate 8 from moving accidentally when cleaning the workbench 1. The position of the pressure plate 8 can be fixed without the user having to manually pull the connecting piece 103, which greatly improves the convenience and practicality of the device. In addition, the design of the rectangular guide hole 107 not only provides space for the bolt 108 to move, but also enhances the stability and reliability of the device.

[0045] The height adjustment component 200 includes two screws 16 rotatably connected to the worktable 1. A mounting bracket 6 is threadedly connected to the two screws 16. A second mounting rod 17 is provided on the worktable 1 near each of the two screws 16. A first connecting plate 18 is fixed to the top of each second mounting rod 17. The top of each screw 16 is rotatably connected to the first connecting plate 18. The bottom ends of the two screws 16 penetrate the worktable 1 and are provided with second helical teeth 15. Support plates 11 are provided on the bottom of the worktable 1 near each of the two second helical teeth 15. Second connecting rods 12 are rotatably connected to the two support plates 11. The outer wall of each second connecting rod 12 is provided with two first helical teeth 13 that cooperate with the two second helical teeth 15. One end of each second connecting rod 12 penetrates one of the support plates 11. A hand crank 14 is provided, and the rotation of the hand crank 14 can drive the rotation of the second connecting rod 12. Since the outer wall of the second connecting rod 12 is provided with a first helical tooth 13 that cooperates with the second helical tooth 15, the rotation of the second connecting rod 12 will drive the two screws 16 to rotate synchronously. Since the mounting bracket 6 is connected to the two screws 16 by threads, the rotation of the two screws 16 will drive the mounting bracket 6 to rise and fall, thereby realizing the height adjustment of the pressure plate 8. This height adjustment component 200 design not only allows the operator to adjust the height according to different cutting needs, but also makes it convenient for the staff to clean the workbench 1, improving the flexibility and practicality of the device. At the same time, the design of the hand crank 14 also makes the operation simpler, and the height adjustment can be completed without the use of complicated tools.

[0046] In use, firstly, the height of the mounting bracket 6 is adjusted by adjusting the height component 200 so that the pressure plate 8 can properly press the OCA optical adhesive to be cut. The operator turns the hand crank 14, and the rotation of the hand crank 14 drives the second connecting rod 12 to rotate. Since the outer wall of the second connecting rod 12 is provided with the first helical tooth 13 that cooperates with the second helical tooth 15, the rotation of the second connecting rod 12 will drive the two screws 16 to rotate synchronously. Since the mounting bracket 6 is connected to the two screws 16 by threads, the rotation of the two screws 16 will drive the mounting bracket 6 and all the components on the mounting bracket 6 to rise and fall, thereby achieving precise adjustment of the height of the pressure plate 8.

[0047] Next, the operator places the OCA optical adhesive to be cut on the worktable 1, and uses the elastic force of the spring 9 to press the OCA optical adhesive with the pressure plate 8 to fix it on the worktable 1. The pressure plate 8 presses the OCA optical adhesive to be cut. During the pressing process, the spring 9 will provide a certain elastic force so that the pressure plate 8 can fit tightly against the OCA optical adhesive and prevent the OCA optical adhesive from shifting position during the cutting process.

[0048] Then, the operator starts cylinder 3, and the output end of cylinder 3 pushes the cutting frame 4 to move towards the OCA optical adhesive to be cut. The cutter 5 on the cutting frame 4 cuts the OCA optical adhesive to be cut. During the cutting process, the pressure plate 8 precisely presses and positions the OCA optical adhesive to be cut, which can greatly improve the cutting accuracy.

[0049] Furthermore, when it is necessary to clean the workbench 1, the operator can pull the connecting piece 103. The connecting piece 103 drives the sliding rod 102 to slide on the mounting tube 101. The sliding rod 102 pushes the insert plate 105 to move towards the mounting tube 101. At this time, the tension spring 104 is stretched. The operator can then pull the first connecting rod 10 to move the pressure plate 8 to the appropriate position. Once in place, the connecting piece 103 is released, and the elastic force of the tension spring 104 will reset the sliding rod 102. The sliding rod 102 then drives the insert plate 105 to move, so that the insert plate 105 passes through the insertion hole 22, thereby storing and fixing the pressure plate 8. In this way, the operator can easily clean the workbench 1, improving the convenience and practicality of the device.

[0050] Example 2

[0051] Please see Figures 7-8 This utility model provides a technical solution:

[0052] Unlike Example 1;

[0053] The outer wall of the hand crank 14 is provided with a gear 30. One side of the gear 30 abuts against the support plate 11. The support plate 11 is also provided with a pair of fixing plates 31. A slide rod 32 is slidably connected to the pair of fixing plates 31. One end of the slide rod 32 is provided with teeth 33. The other end of the slide rod 32 is connected to a pull ring 34.

[0054] A limiting rod 36 is provided on the support plate 11 above the fixing piece 31. A limiting piece 37 is provided at one end of the limiting rod 36. A return spring 35 is sleeved on the outer wall of the slide rod 32. The two ends of the return spring 35 abut against the teeth 33 and one of the fixing pieces 31 respectively.

[0055] When the hand crank 14 is in its fixed position, the return spring 35 will be in its initial state (e.g., Figure 8 (As shown), press against the tooth 33 to ensure that the tooth 33 meshes with the gear 30, thereby firmly fixing the hand crank 14;

[0056] When the hand crank 14 needs to be rotated, the operator can pull the pull ring 34. The pull ring 34 will drive the slide bar 32 to slide on the fixed plate 31. The slide bar 32 will then push the tooth 33 to move away from the gear 30. At this time, the return spring 35 is compressed and the pull ring 34 is hooked on the limit rod 36, thereby locking the position of the tooth 33. At this time, the hand crank 14 can be rotated.

[0057] Once the teeth 33 disengage from the gear 30, the operator can freely rotate the hand crank 14, thereby driving the height adjustment component 200 to work. When the hand crank 14 is adjusted to the desired position, the pull ring 34 is released, and the elasticity of the return spring 35 will cause the slide rod 32 to return to its original position. The slide rod 32 then drives the teeth 33 to move, so that the teeth 33 re-engage with the gear 30, thereby firmly fixing the hand crank 14. This design not only simplifies the fixing and releasing process of the hand crank 14, but also improves the safety and stability of the device. In addition, the design of the limit rod 36 and the limit piece 37 can prevent the slide rod 32 from sliding excessively, thereby further enhancing the reliability and practicality of the device.
