In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

1 to 2, an optical glass transmittance detection device includes a working platform 1 and a detection frame used to cooperate with the working platform 1. The working platform 1 is used to place the optical glass, and the detection frame is used to realize the light transmittance detection of the optical glass. Specifically:

A testing platform 2 and a driving device 3 for driving the testing platform 2 to rotate are installed on the working platform 1. A plurality of card slots 4 for facilitating the placement of optical glass are arranged in the circumference of the testing platform 2. A testing hole 5 connected to the card slot 4 is arranged at the top and bottom of the testing platform 2 at the card slot 4. The card slot 4 is arranged to facilitate the taking and placing of the optical glass, and is used to place the optical glass on the testing platform 2. In order to avoid scratching the optical glass, a rubber pad can also be pasted on the inner wall of the card slot 4. The driving device 3 is used to drive the testing platform 2 to rotate, thereby facilitating the rotation of the optical glass placed on the testing platform 2, so as to facilitate the light transmittance detection operation of the optical glass in turn. The detection hole 5 is arranged to facilitate the use of light to illuminate the optical glass in the card slot 4 to perform light transmittance detection operation.

One side of the working platform 1 is shorter than the detection platform 2 and is set as the detection side. The detection frame is set on the detection side of the working platform 1. The detection frame includes a base 6 and a vertical support rod 7 vertically fixedly installed on the base 6. A lower cross bar 12 is installed at the lower part of the vertical support rod 7. A detection lamp 13 extending to the bottom of the detection hole 5 is installed on the lower cross bar 12. An upper cross bar 8 is installed at the upper part of the vertical support rod 7. A detection board 10 extending to the top of the detection hole 5 is installed on the upper cross bar 8. A brightness sensor 11 cooperating with the detection lamp 13 is installed on the detection board 10. The detection lamp 13 is used to illuminate the optical glass in the card slot 4 from below, and the brightness sensor 11 is used to detect the intensity of light passing through the optical glass from above. If the detected light intensity is lower than the set value, it means that the light transmittance of the optical glass does not meet the requirements;

In order to realize the automatic detection operation, a control box 16 is also installed on the base 6, a controller is installed in the control box 16, a display screen 17 and an audible and visual alarm 18 are installed on the control box 16, the brightness sensor 11 is connected to the input end of the controller, and the driving device 3, the detection light 13, the display screen 17 and the audible and visual alarm 18 are all connected to the output end of the controller. The controller is used to receive the detection signal of the brightness sensor 11 in real time, and when the detected light intensity does not meet the requirements, the audible and visual alarm 18 is controlled to send out an audible and visual alarm signal to remind the worker that the light transmittance of the optical glass does not meet the requirements. Preferably, the controller adopts a PLC or CPU controller; the display screen 17 is used to display the light intensity detected by the brightness sensor 11 in real time;

Preferably, a rotating shaft is fixedly installed at the bottom of the detection platform 2, and the rotating shaft is installed on the working platform 1 through bearings and bearing seats. The driving device 3 is a stepper motor, and the stepper motor is installed on the working platform 1. The motor shaft of the stepper motor is connected to the rotating shaft by transmission. The stepper motor can drive the rotating shaft to drive the detection platform 2 to rotate, and can control the rotation angle of the detection platform 2 as needed, thereby realizing the rotation position control of the detection platform 2, so as to better cooperate with the detection operation.

In order to adjust the position of the detection lamp 13 and the detection plate 10, the lower cross bar 12 and the upper cross bar 8 are installed on the vertical support rod 7 through a sliding sleeve 14, and a locking bolt 15 cooperating with the vertical support rod 7 is rotated on the sliding sleeve 14. A length scale line is provided on the vertical support rod 7, so that the lower cross bar 12 and the upper cross bar 8 can be adjusted by sliding the sleeve 14 as needed, thereby adjusting the position of the detection lamp 13 and the detection plate 10 to meet different detection requirements; the locking bolt 15 is used to fix the sliding sleeve 14 after the position is adjusted to ensure the reliability of the detection lamp 13 and the detection plate 10.

In order to minimize the influence of external light on the brightness sensor 11, a vertically arranged detection tube 9 is fixedly installed on the upper cross bar 8, the top of the detection tube 9 is closed, and the detection plate 10 is installed in the detection tube 9; in actual use, a small room can also be set up in the workshop, and the equipment of the present application can be placed in the small room to facilitate the control of the intensity of external light.

Specifically, a limit switch 19 can be installed on the working platform 1 at the detection frame, and a limit plate 20 cooperating with the limit switch 19 can be installed on the detection platform 2 at each slot 4. Through the cooperation of the limit plate 20 and the limit switch 19, the slot 4 on the detection platform 2 can accurately stay at the detection frame, so that the optical glass in the slot 4 can be tested for light transmittance using the detection light 13 and the detection plate 10.

Preferably, the working platform 1 is in the shape of a cuboid, and the detection platform 2 is in the shape of a disc.

When in use, first move the detection frame to the work platform 1, and make the detection light 13 and the detection board 10 on the detection frame align with one of the slots 4 on the detection platform 2, and adjust the height of the detection light 13 and the detection board 10. Then, the worker places the optical glass into the slot 4 of the detection platform 2 at the downstream of the rotation direction of the detection platform 2. If there is already optical glass in the slot 4, take it out and replace it with a new optical glass; then, turn on the driving device 3, the detection light 13, the controller, the display screen 17, and the sound and light alarm 18, and use the detection light 13 and the brightness sensor 11 on the detection board 10 to realize the light transmittance detection of the optical glass in the slot 4. If the light intensity detected by some brightness sensors 11 is lower than the set value, the controller controls the sound and light alarm 18 to send a sound and light alarm signal to remind the worker that the light transmittance of the glass does not meet the requirements;

The detection time is pre-set, generally 5-10 seconds, and then the detection is stopped for 10-20 seconds, so that the driving device 3 drives the detection platform 2 to rotate, and the next card slot 4 is rotated to the detection frame for re-detection. This reciprocating cycle is repeated, and workers only need to perform the operation of taking and placing the optical glass. The operation requirements are low, the use cost is low, and the detection efficiency is high, which can well meet the actual use needs in the workshop production and manufacturing process.
