Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figures 1-3 The optical inspection instrument for holographic projection glass production shown includes a conveyor frame 1, a conveyor belt 2 on the top of the conveyor frame 1, and multiple evenly distributed glass fixtures 3 on the surface of the conveyor belt 2. Each glass fixture 3 includes a fixture plate 4, a fixing frame 5 fixedly mounted on the surface of the fixture plate 4, two clamping plates 6 symmetrically mounted inside the fixing frame 5, and a first spring 7 fixedly mounted between the sides of the two clamping plates 6 and the inner wall of the fixing frame 5. A light-transmitting detection hole 8 is opened at the center of the surface of the fixture plate 4 to ensure light transmission. Mounting holes 9 are opened at the four corners of the surface of the fixture plate 4, and bolts can be inserted into the mounting holes 9 to fix them to the surface of the conveyor belt 2. A detection box 10 is fixedly mounted on the top of the conveyor frame 1 and above the conveyor belt 2. An optical detection head 11 is fixedly mounted inside the detection box 10. A display 15 is fixedly mounted on one side of the top of the conveyor frame 1, and an alarm light 16 is fixedly mounted on the top of the detection box 10. A controller is also installed inside the detection box 10. The optical detection head 11, the display 15, and the alarm light 16 are all electrically connected to the controller.

[0025] During testing, the holographic projection glass is first placed inside the fixed frame 5. Then, by pressing the clamping plates 6 on both sides, the clamping plates 6 compress the first spring 7, which in turn causes the clamping plates 6 to elastically clamp the sides of the holographic projection glass. This allows the holographic projection glass to be stably installed inside the glass fixture 3, preventing the holographic projection glass from shifting during transport. When the holographic projection glass passes through the testing box 10 along with the conveyor belt 2, the optical detection head 11 can detect the clarity, brightness, and color of the holographic projection glass. The detected image is displayed to the operator through the display 15, improving the accuracy of the holographic projection glass detection. If a defective product is found, the alarm light 16 will alert the operator.

[0026] In order to be able to wipe the surface of the holographic projection glass, such as Figure 2 and 4 As shown, a U-shaped frame 12 is fixedly installed on the top of the conveyor frame 1 and on one side of the detection box 10. A cylinder 13 is fixedly installed on the top of the U-shaped frame 12. A glass wiping plate 14 is elastically provided at the end of the piston rod of the cylinder 13. By controlling the extension and retraction of the cylinder 13, the glass wiping plate 14 can be adjusted up and down to contact the surface of holographic projection glass of different thicknesses. The glass wiping plate 14 consists of a plate body and a wiping rubber sheet. The wiping rubber sheet is fixedly installed on the lower surface of the plate body. The wiping rubber sheet has a good wiping effect on the surface of the holographic projection glass and can wipe away impurities on the surface of the holographic projection glass.

[0027] Finally, in order to enable the glass cleaning plate 14 to have the function of elastic extension and retraction, such as Figure 4 As shown, a mounting base 17 is fixedly provided at the end of the piston rod of the cylinder 13. Sliding rods 18 are slidably provided on both sides of the mounting base 17. The lower ends of the two sliding rods 18 are fixedly connected to the upper surface of the glass wiping plate 14. A second spring 19 is provided at the upper end of the two sliding rods 18. The upper end of the sliding rod 18 is set as a T-shaped structure. The two ends of the second spring 19 are fixedly connected to the upper end of the sliding rod 18 and the top of the mounting base 17, respectively. When holographic projection glass of different thicknesses comes into contact with the lower code of the glass wiping plate 14, the glass wiping plate 14 moves upward through the sliding rods 18 and compresses the second spring 19, thereby playing an upward avoidance role and preventing the glass wiping plate 14 from being damaged due to excessive external force when it comes into contact with the holographic projection glass.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
