[0003] Chinese patent discloses a rapid detection device for the coating quality of double-layer thermal CTP plates (publication number: CN210155046U). This patent uses a first motor to drive a first gear to rotate clockwise and counterclockwise, and then the first gear drives a half gear to rotate synchronously. Through the cooperation of a rotating groove and a rotating plate, the support plate rotates back and forth around the center point of the fixed block. By illuminating the plate with an inclined light, the inspectors on the opposite side can more quickly detect the quality of the CTP plate. However, the angle between the CTP plate and the illuminating lamp in this patent has certain limitations, so it is difficult to find abnormalities in the CTP plate. Summary of the Invention

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-5As shown, this invention is a composite CTP plate performance testing device, including a support frame 1, a rotating ring 2, and an installation assembly 3. The rotating ring 2 can be rotated freely by the operator's hand, facilitating easy adjustment. Fixed sleeves 4 are provided through both sides of the support frame 1, and limiting cavities 5 are provided through both sides of the rotating ring 2. The inner surface of the limiting cavity 5 is rotatably connected to the outer surface of the fixed sleeve 4. A limiting ring 6 is fixedly connected to the outer surface of the fixed sleeve 4. By manually rotating the rotating ring 2, the limiting ring 6 rotates within the limiting cavity 5, thereby adjusting the illumination angle of the illumination lamp 16 on the rotating ring 2. The outer surface of the limiting ring 6 is slidably connected to the inner surface of the limiting cavity 5. A stepped cavity 8 is provided inside the fixed sleeve 4. Connecting sleeves 7 are fixedly connected to both sides of the installation assembly 3. A sliding groove 11 is provided on one side of the connecting sleeve 7. Several limiting grooves 12 are provided on the inner surface of the sliding groove 11. The stepped cavity 8... A sliding rod 9 is slidably connected to the surface of the sliding rod 9. Several limiting strips 13 are fixedly connected to the outer surface of the sliding rod 9. When the limiting strips 13 are inserted into the limiting groove 12, they can limit the installation component 3 and prevent the installation component 3 from rotating at will. The outer surface of the limiting strips 13 is adapted to the inner surface of the limiting groove 12. A tension spring 10 is sleeved on the outer surface of the sliding rod 9. One end of the tension spring 10 is fixedly connected to one side of the fixed sleeve 4. Movable illumination lamps 16 are provided on both sides of the inner surface of the rotating ring 2. The illumination lamps 16 are existing technology. The CTP plate is irradiated by the illumination lamps 16. By setting two through fixed rod sleeves on the support frame 1, and cooperating with the connecting sleeve 7 in the fixed sleeve 4 and the sliding of the sliding rod 9, when the limiting strips 13 on the sliding rod 9 are pulled out from the inside of the limiting groove 12, the angle of the installation component 3 can be rotated, thereby adjusting the position of the CTP plate. By adjusting the observation angle of the CTP plate through this structure, the quality of the CTP plate can be observed more precisely.

[0027] Please see Figure 4 As shown, arc-shaped grooves 14 are provided on both sides of the inner surface of the rotating ring 2. Arc-shaped stepped blocks 15 are slidably connected to the inner surface of the arc-shaped grooves 14. When the arc-shaped stepped blocks 15 slide on the inner surface of the arc-shaped grooves 14, they have a certain resistance, so that the position of the illumination lamp 16 on the arc-shaped stepped blocks 15 will not change arbitrarily. The cross-section of the arc-shaped stepped blocks 15 is stepped. One side of the arc-shaped stepped blocks 15 is fixedly connected to one side of the illumination lamp 16. By opening arc-shaped grooves 14 on the inner surface of the rotating ring 2 and cooperating with the arc-shaped stepped blocks 15 on the inner surface of the arc-shaped grooves 14, the tilt angle of the illumination lamp 16 can be adjusted by installing the illumination lamp 16 on the arc-shaped stepped blocks 15. At the same time, the rotating ring 2 can rotate on the outer surface of the limiting ring 6, thereby adjusting the horizontal angle of the illumination lamp 16 and further improving its illumination effect.

[0028] Please see Figure 4 and Figure 5 As shown, the mounting assembly 3 includes a mounting plate 31. The top of the mounting plate 31 has a translucent groove 32. Both sides of the inner wall of the translucent groove 32 have a storage groove 33. The front and rear sides of the surface of the mounting plate 31 have threaded holes. The inner surfaces of the two threaded holes are threaded with threaded rods 34. The relatively far ends of the two threaded rods 34 are fixedly connected to a rotating handle 17. The relatively close ends of the two threaded rods 34 are rotatably connected to a support plate 35. Since the support plate 35 cannot rotate under the limitation of the storage groove 33, the two support plates 35 will move towards the relatively close side, thereby adjusting the distance between the two support plates 35. The cross-section of the support plate 35 is L-shaped.

[0029] The mounting plate 31 is fixedly connected to four sides of its top with fixed posts 36. A rotating plate 37 is rotatably connected to the top of the fixed posts 36. A telescopic rod 39 is fixedly connected to the bottom of the rotating plate 37. A telescopic sleeve 310 is slidably connected to the outer surface of the telescopic rod 39. A rubber sleeve 311 for pressing the CTP plate is fixedly connected to the outer surface of the telescopic sleeve 310. A telescopic cavity 38 is opened inside the telescopic sleeve 310. A compression spring 312 is sleeved on the outer surface of the telescopic rod 39 and inside the telescopic cavity 38. The top of the compression spring 312 is fixedly connected to the top of the inner cavity of the telescopic cavity 38. By setting fixed posts 36 on the top of the mounting plate 31, cooperating with the telescopic rod 39 on the rotating plate 37, and using the compression spring 312, the rubber sleeve 311 can press the CTP plate on the mounting plate 31. An object groove 33 is opened on the inner surface of the translucent groove. The support plate 35 can accommodate CTP plates with a small area, thereby further improving its practicality.

[0030] In this invention, the mounting assembly 3 can limit the position of CTP plates of different specifications. When the area of ​​the CTP plate is smaller than the area of ​​the translucent groove 32, the two support plates 35 rotate on the inner surface of the placement groove 33 to the side that is relatively close to each other. Then the CTP plate is placed between the two support plates 35. Then the rotating plate 37 is rotated to the top of the support plate 35. Then the four telescopic sleeves 310 are pushed upward and the compression spring 312 is compressed. Then the CTP plate is placed on the top of the mounting plate 31. Then the telescopic sleeves 310 are released. At this time, the telescopic sleeves 310 will move downward under the action of the telescopic rod 39, thereby pressing the CTP plate on the support plate 35.

[0031] When the area of ​​the CTP plate is larger than the area of ​​the translucent groove 32, similarly, by rotating the position of the rotating plate 37, the rubber sleeve 311 on the telescopic sleeve 310 is positioned between the CTP plate and the mounting plate 31, thus pressing the CTP plate down.

[0032] The working principle of this invention is as follows: First, the CTP plate is placed on the mounting plate 31 in the mounting assembly 3. If the area of ​​the CTP plate is larger than the area of ​​the mounting plate 31, the rotating plate 37 is rotated so that it is positioned above the mounting plate 31. Then, the four telescopic sleeves 310 are pushed upwards, compressing the compression spring 312. Next, the CTP plate is placed on top of the mounting plate 31, and then the telescopic sleeves 310 are released. At this point, the telescopic sleeves 310 will move downwards under the action of the telescopic rod 39. The rubber sleeve 311 presses the CTP plate on the mounting plate 31 tightly. When the area of ​​the CTP plate is smaller than the area of ​​the mounting plate 31, the rotating handle 17 is turned to make the threaded rod 34 rotate on the inner surface of the threaded hole, thereby causing the two support plates 35 to rotate towards each other on the inner surface of the storage slot 33. Then, the CTP plate is placed between the two support plates 35, and the rotating plate 37 is rotated above the support plates 35. Finally, the four telescopic sleeves 310 are pushed upwards, causing the compression spring 312 to be in a state of... In the compressed state, the CTP plate is placed on top of the mounting plate 31, and then the telescopic sleeve 310 is released. At this time, the telescopic sleeve 310 will move downward under the action of the telescopic rod 39, thereby pressing the CTP plate on the support plate 35. At this time, the sliding rod 9 is pulled, so that the limiting strip 13 on the sliding rod 9 is pulled out from the limiting groove 12 in the sliding groove 11, so that the tension spring 10 is stretched. At this time, the rotating ring 2 can be pushed, so that the limiting cavity 5 in the rotating ring 2 slides with the limiting ring 6, thereby adjusting the rotating ring 2 and the mounting assembly. The angle between 3 and 4 is adjusted, and then the sliding rod 9 is removed. After removing the sliding rod 9 again, the sliding rod 9 is slid from the stepped cavity 8 into the sliding groove 11 under the action of the tension spring 10, so that the limiting strip 13 is inserted into the limiting groove 12, thereby fixing the connecting sleeve 7. Then the illumination lamp 16 is turned on so that the illumination lamp 16 illuminates the CTP plate. At this time, the operator can push the arc-shaped stepped block 15 on the illumination lamp 16 to slide on the inner surface of the arc-shaped groove 14, thereby realizing multi-angle illumination of the CTP plate.
