Description

Technical Field

[0001] The utility model relates to the technical field of lens detection, in particular to a light transmission detection device. Background Technique

[0002] Optical glass was originally the glass used to make lenses, which was ordinary window glass or the bumps on wine bottles. Its shape was similar to a "crown", and thus the name crown glass or crown plate glass came from. It was made by mixing oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melting them at high temperature in a platinum crucible, stirring evenly with ultrasonic waves to remove air bubbles; then cooling slowly for a long time to avoid internal stress in the glass block. The cooled glass block must be measured by optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications. The qualified glass block is heated and forged into a blank of an optical lens.

[0003] The prior art patent document with the publication number CN216566849U provides an optical glass lens light transmission detection device. In this optical glass lens light transmission detection device, through the design of the installation mechanism, the moving plate is pulled to one side. The moving plate drives the limiting block to move, and the limiting block squeezes the spring. When the moving plate drives the clamping plate not to fit with the first threaded rod, the circular plate is rotated. The circular plate drives the first threaded rod to rotate. After the first threaded rod rotates, it drives the pressing plate to move downward. After the pressing plate moves downward, it pushes the L-shaped plate downward. The L-shaped plate drives the clamping plate to move. When the rubber pad body on the clamping plate is in close contact with the top of the glass lens body, the moving plate is released to complete the installation of the glass lens body. The entire installation process is simple, convenient, and easy to operate. However, in the existing CN216566849U patent, the detection of the glass lens is not continuous. When a glass lens is detected, it needs to be removed, and then a new glass lens is replaced. Removing and installing the glass lens takes a certain amount of time, and during this process, the detection stagnates, resulting in an extended overall detection time of the glass lens and low detection efficiency. Therefore, there is an urgent need for a light transmission detection device. Content of the Utility Model

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as limiting the present utility model.

[0023] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0024] Please refer to Figures 1 - 5 , a light transmission detection device, including a detection table 1 and a clamping mechanism 8. A controller 2 is provided at the front end of the detection table 1. A suspension plate 3 is arranged in parallel at the upper end of the detection table 1, and mounting plates 4 are arranged on both the left and right sides of the suspension plate 3. A groove 5 is provided on the side of the mounting plate 4 close to the suspension plate 3, and threaded holes 6 are provided on both the inner side of the groove 5 and the suspension plate 3. Screws 7 penetrate through the threaded holes 6. The left and right sides of the suspension plate 3 are inserted into the groove 5, and the mounting plate 4 and the suspension plate 3 are assembled by the screws 7. This setting makes the suspension plate 3 and the mounting plate 4 detachable, facilitating the replacement of the mounting plate 4 alone;

[0025] The clamping mechanism 8 is arranged inside the mounting plate 4. The clamping mechanism 8 includes a large circular groove 801, a small circular groove 802, a spring 803, an arc-shaped clamping plate 804 and a rubber pad 805. A small circular groove 802 is opened at the lower end of the middle part of the large circular groove 801, and a spring 803 is connected to the inner wall of the large circular groove 801. The other end of the spring 803 is connected to the arc-shaped clamping plate 804, and a rubber pad 805 is attached to the inner wall of the arc-shaped clamping plate 804. The lens is clamped and fixed by the clamping mechanism 8 to ensure the stability of the lens during the detection process. There are two arc-shaped clamping plates 804 arranged inside each large circular groove 801, and the two arc-shaped clamping plates 804 are symmetric about the vertical central axis of the small circular groove 802. The lens is placed between the two arc-shaped clamping plates 804, and the lens is fixed by the two arc-shaped clamping plates 804. The settings of the spring 803 and the rubber pad 805 provide buffering for the fixation of the lens, avoiding damage to the lens during the fixation process. At the same time, under the action of the spring 803, lenses of different sizes can be fixed, and the process of taking and placing the lens is simple and easy to operate. The top end of the hanging plate 3 is fixedly connected with a vertical rod 9, and a motor 10 is installed at the top end of the vertical rod 9. The top end of the motor 10 is fixed with a first top plate 11, and a first support plate 12 is welded below the right end of the first top plate 11. The lower end of the first support plate 12 is fixed to the detection table 1, and the detection table 1 is parallel to the mounting plate 4. The motor 10 is supported by the first top plate 11 and the first support plate 12, enabling the motor 10 to output stably. The motor 10 drives the vertical rod 9 and the hanging plate 3 to rotate through the output shaft. Since the mounting plate 4 is assembled on the left and right sides of the hanging plate 3, the mounting plate 4 can rotate. When one lens is detected, the hanging plate 3 is controlled to rotate, rotating another undetected lens under the irradiation lamp 13, and at the same time, the detected lens is removed and replaced. The taking and placing of the lens and the detection of the lens can be achieved simultaneously. This setting realizes the continuity of lens detection and improves the lens detection efficiency. A second support plate 16 is fixed to the left side of the top end of the detection table 1, and a second top plate 15 is welded to the right side of the top end of the second support plate 16. A hydraulic cylinder 14 is arranged below the second top plate 15, and the lower end of the hydraulic cylinder 14 is connected to the irradiation lamp 13. A detection hole 17 is arranged on the upper surface of the detection table 1, and the central axes of the irradiation lamp 13 and the detection hole 17 are on the same straight line. Through this setting, the light emitted by the irradiation lamp 13 directly passes through the lens and passes out of the small circular groove 802 to reach the detection hole 17, improving the accuracy of lens detection.

[0026] Working principle: When in use, place the lens between the two arc-shaped clamping plates 804. Fix the lens through the two arc-shaped clamping plates 804. The settings of the spring 803 and the rubber pad 805 provide buffering for the fixation of the lens, avoiding damage to the lens during the fixation process. At the same time, under the action of the spring 803, lenses of different sizes can be fixed. After the lens is fixed, the light emitted by the irradiation lamp 13 directly passes through the lens and exits through the small round groove 802 to reach the detection hole 17, detecting the light transmittance of the lens. When one lens is detected, drive the vertical rod 9, the hanging plate 3 and the mounting plate 4 to rotate through the motor 10, rotate the other undetected lens under the irradiation lamp 13, and at the same time remove the detected lens and replace it with a new lens. The picking and placing of the lens and the detection of the lens in this device can be carried out simultaneously, saving time and accelerating the lens detection efficiency. The clamping of the lens is mainly realized by the spring 803 and the arc-shaped clamping plate 804. When the elasticity of the spring 803 decreases due to long-term use, only remove the screw 7 to replace and install the mounting plate 4, thereby realizing the replacement of the spring 803.

[0027] The control mode of this device is automatically controlled by the controller 2. The control circuit of the controller 2 can be realized by simple programming by those skilled in the art and belongs to the common general knowledge in this field. Therefore, the control mode and circuit connection of this device will not be explained in detail.
