[0002] Optical OCA release film is a special series of release films developed for applications such as optical adhesive coating or optical tape processing. It has excellent physical and mechanical properties, small thickness tolerance, high heating temperature, low thermal shrinkage rate, and good flexibility. Optical film die-cutting is the process of die-cutting several small optical films from a large sheet of optical film. Dimension inspection table refers to mechanical equipment used to inspect and verify the dimensions of specific workpieces.

[0003] First, gently place the optical film on the inspection table, ensuring it is completely flat. Then, select the appropriate measurement method based on the size characteristics and accuracy requirements of the OCA optical film. If using calipers, gently bring the caliper jaws into contact with the edge of the optical film, ensuring the calipers are perpendicular to the film. Read the dimensional data on the caliper display screen and accurately record the data from each measurement.

[0004] In the die-cutting process of OCA optical films, the cutting tool cuts the optical film, and the tiny particles generated during the cutting process form dust particles. These dust particles adhere to the surface of the optical film, affecting the accuracy of subsequent dimensional inspection. Therefore, a dimensional inspection table for OCA optical film die-cutting is proposed to solve this problem. Summary of the Invention

[0026] 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.

[0027] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of a dimensional inspection table for OCA optical film die-cutting, comprising a processing box 1. Support legs are fixedly connected to the four corners of the bottom of the processing box 1, providing support for the processing box 1. Openings are provided on both sides of the processing box 1, with light-shielding curtains 3 fixedly connected to the openings. This light-shielding design effectively prevents optical performance degradation caused by light exposure, ensuring the stability of the optical film's performance during the inspection process. A top plate 7 is fixedly connected to the top of the processing box 1, and a No. 1 motor is fixedly installed on the back of the top plate 7. The top plate 7 is used to install the No. 1 motor, and a rotating rod 9 is fixedly connected to the output shaft of the No. 1 motor. The output shaft of the No. 1 motor drives the rotating rod 9 to rotate. An elliptical cam 10 is fixedly connected to the other end of the rotating rod 9. The other end can drive the elliptical cam 10 to rotate. A tank 8 is fixedly connected to the top of the processing box 1. A piston rod 25 is movably connected through the top of the tank 8. The piston rod 25 can move upwards along the inner wall of the tank 8. A pressure plate 18 is fixedly connected to the top of the piston rod 25, increasing the contact surface at the top of the piston rod 25. A spring 19 is sleeved on the surface of the piston rod 25. Both ends of the spring 19 are fixedly connected to the pressure plate 18 and the adjacent side of the tank 8, respectively. Through the longitudinal elastic potential energy of the spring 19, the pressure plate 18 can rebound after being compressed. The edge of the elliptical cam 10 abuts against the top of the pressure plate 18, allowing the elliptical cam 10 to reciprocate and compress the pressure plate 18 upon rotation. A piston plate 20 is fixedly connected to the bottom end of the piston rod 25. The edge is in sealed contact with the inner wall of the tank 8. Since the piston plate 20 is fixed to the piston rod 25, the piston plate 20 moves with the piston rod 25. A two-way pipe 6 is fixedly connected to the outer wall of the tank 8. Due to the setting of the one-way valve B, the gas inside the tank 8 exits through the two-way pipe 6 and cannot enter the tank 8 through the two-way pipe 6. Therefore, when the piston plate 20 moves downward, the air inside the tank 8 is discharged through the two-way pipe 6 and the air pipe 16. Due to the setting of the one-way valve A, air can only enter the tank 8 through the air inlet pipe 27. Therefore, when the piston plate 20 moves upward, external air is drawn into the tank 8 through the air inlet pipe 27. There is a gap where the piston rod 25 passes through the tank 8, which allows the air above the piston plate 20 to be discharged outward. The air inlet pipe 27 is fixedly connected to the outer wall of the tank 8. One end of the air inlet pipe 27 is connected to the inside of the tank 8. A one-way valve A is fixedly installed at the connection between the air inlet pipe 27 and the tank 8. A one-way valve B is fixedly installed at the connection between the two-way pipe 6 and the tank 8. Two sliding holes 2 are opened on the front of the processing box 1. The sliding holes 2 are strip-shaped. The surface of the two-way pipe 6 contacts and slides with the hole walls of the two sliding holes 2 respectively. The sliding holes 2 limit the movement of the two-way pipe 6, making the sliding of the two-way pipe 6 more stable. The other end of the two-way pipe 6 is fixedly connected to the air pipe 16. The two ends of the two-way pipe 6 are connected to the tank 8 and the air pipe 16 respectively. The processing box 1 is equipped with a moving component. The moving component works with the air pipe 16 to clean the dust on the surface of the OCA optical film.

[0028] Reference Figure 2 , Figure 3 , Figure 5 The moving component includes a second motor 12, which is fixedly installed on the outer wall of the other side of the processing box 1. The output shaft of the second motor 12 is fixedly connected to a threaded rod 26, which can drive the threaded rod 26 to rotate. The other end of the threaded rod 26 is rotatably connected to the inner wall of the processing box 1 through a bearing. The other end of the threaded rod 26 can rotate around the inner ring of the bearing, improving the stability of the threaded rod 26 during rotation. A slider 13 is threadedly fitted on the surface of the threaded rod 26. A scraper 17 is fixedly connected to the bottom of the slider 13. The bottom of the scraper 17 contacts and slides against the bottom inner wall of the processing box 1. A dust outlet 24 is opened on the adjacent bottom inner wall. As the slider 13 moves, it drives the scraper 17 to move, and the scraper 17 is used to concentrate and move the dust on the inner wall of the processing box 1. The dust is discharged through the dust outlet 24.

[0029] Reference Figure 1 , Figure 2 , Figure 4 A fixing component is provided above the slider 13. The fixing component includes a top frame 22, which is fixedly connected to the top of the slider 13. The top frame 22 is L-shaped and has a threaded hole at its top. A stud 23 is threadedly connected to the inner wall of the threaded hole. The stud 23 can move within the threaded hole of the top frame 22. A knob 11 is fixedly connected to the top of the stud 23 for easy rotation by the operator. A pressure block 14 is fixedly connected to the bottom of the stud 23, and a pad 15 is fixedly connected to the top of the slider 13. The stud 23 drives the pressure block 14 to move downward until the pressure block 14 presses the OCA optical film against the top of the pad 15. With the help of the moving component, OCA optical films of different thicknesses can be clamped, fixed and pulled.

[0030] Reference Figure 1 , Figure 2 A feeding assembly is provided on one side of the processing box 1. The feeding assembly includes an extension plate 4. An unwinding shaft 5 is rotatably connected to the inner wall of the extension plate 4, which facilitates the rolling of the OCA optical film into a roll after die-cutting and fixing it on the unwinding shaft 5. One end of the unwinding shaft 5 is connected to one end of the rotating rod 9 through a pulley and belt drive. Since the rotating rod 9 and the unwinding shaft 5 are connected through a pulley and belt drive, the rotating rod 9 drives the unwinding shaft 5 to rotate during rotation. The rotation of the unwinding shaft 5 is used to unwind the die-cut OCA optical film. Several rollers 21 are fixedly connected to the inner wall of the processing box 1. The surface of the rollers 21 is provided with grooves. The rollers 21 are symmetrically arranged at equal intervals. The grooves on the rollers 21 limit the two sides of the OCA optical film.

[0031] Working principle: After die-cutting, the OCA optical film is rolled into a cylinder and fixed onto the unwinding shaft 5. Then, the first motor is started, causing its output shaft to drive the rotating rod 9 to rotate. Since the rotating rod 9 and the unwinding shaft 5 are connected by a pulley and belt drive, the rotating rod 9 drives the unwinding shaft 5 to rotate during its rotation. The rotation of the unwinding shaft 5 unwinds the die-cut OCA optical film, positioning the unwinding end between the pressure block 14 and the pad 15. Then, the knob 11 is turned, causing the stud 23 to rotate. The stud 23 then moves the pressure block 14 downwards until it presses the OCA optical film against the top of the pad 15. During the rotation of the rotating rod 9, the elliptical cam 10 rotates. Utilizing the longitudinal elastic potential energy of the spring 19, the elliptical cam 10 reciprocates by pressing the pressure plate 18, causing the pressure plate 18 to drive the piston rod 25 to move up and down. Since the piston plate 20 is fixed to the piston rod 25, the piston plate 20 follows the piston rod 25. When the stopper plate 20 moves downward, the air inside the tank 8 is discharged through the two-way pipe 6 and the air pipe 16. When the piston plate 20 moves upward, the external air is drawn into the tank 8 through the cooperation of the air inlet pipe 27 and the one-way valve A. The piston rod 25 passes through the gap created at the tank 8, which can discharge the air on the upper layer of the piston plate 20 to the outside. Then, the second motor 12 is started, and the output shaft of the second motor 12 drives the threaded rod 26 to rotate. The threaded rod 26 drives the slider 13 to move. The upper clamp of the slider 13 pulls one end of the OCA optical film. During the movement of the slider 13, the air pipe 16 discharges air to clean the dust on the surface of the OCA optical film until one end of the OCA optical film extends into the other side of the processing box 1. The groove on the roller 21 limits the two sides of the OCA optical film. During the movement of the slider 13, the scraper 17 moves. The scraper 17 is used to concentrate and move the dust on the inner wall of the processing box 1. The dust is discharged through the dust outlet 24.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
