[0028] Such as Figures 1 - 10 As shown in the figure, an optical performance detection device for an optical product includes a bracket 1. The outer wall A2 of the bracket 1 is perpendicular to the outer wall B3. A product fixing jig 4 is provided on the outer wall A2 through a rotating mechanism. The rotating shaft of the rotating mechanism is perpendicular to the outer wall A2. A light detection device 5 is provided on the outer wall A2. An arc track 6 is provided on the outer wall A2. The connecting line segment between the center of the virtual circle where the arc of the arc track 6 is located and the light detection device 5 is perpendicular to the outer wall B3. The plane where the virtual circle is located is parallel to the outer wall B3. A moving seat 7 is slidably provided between the two ends of the arc track 6. A light source 8 is provided on the moving seat 7. The light emitted by the light source 8 is directed towards the light detection device 5. A driving device is provided on the bracket 1, and the driving device can drive the moving seat 7 to move on the arc track 6.

[0029] In this embodiment, when in use, an optical product (lens) is installed on the fixing jig 4. At this time, the optical product (lens) is parallel to the outer wall A2. Then, the driving device can be used to drive the moving seat 7 to move on the arc track 6, so as to measure the refraction of light when it irradiates the optical product from different angles. After the light is emitted from the light source 8, it penetrates through the optical product and enters the light detection device 5 (light detection sensor), and the qualification of the optical product can be comprehensively detected. When the rotating mechanism rotates, the lens fixed on the fixing jig 4 is driven to rotate, so that different positions on the lens can be detected.

[0030] As a preferred method, the light emitted by the light source 8 is parallel to the outer wall B3. In this way, the test results are more accurate.

[0031] As a preferred method, the driving device is a servo motor 9.

[0032] Specifically, the output shaft of the servo motor 9 is parallel to the outer wall A2, the output shaft of the servo motor 9 is perpendicular to the outer wall B3. A connecting arm 10 is radially provided on the output shaft of the servo motor 9. An installation shaft 11 is arranged on the connecting arm 10. The moving seat 7 is fixedly arranged on the side of the installation shaft 11 facing the fixed jig 4. A hanging plate 12 is fixedly arranged on the side of the installation shaft 11 facing away from the fixed jig 4. The connecting arm 10 fixedly connects the installation shaft 11 between the arc-shaped track 6 and the moving seat 7. The hanging plate 12 contacts the upper surface of the arc-shaped track 6 at a position far from the installation shaft 11. After such a setting, when the output shaft of the servo motor 9 rotates, it drives the connecting arm 10 to rotate, thereby dragging the moving seat 7 to move on the arc-shaped track 6. The setting of the hanging plate 12 enables the hanging plate 12 to play a role in pulling the connecting arm 10 at the free end of the connecting arm 10 when the outer wall 8 is used as the upper surface of the bracket 1 (such as Figure 1 , Figure 2 , Figure 4 , Figure 9 shown), so as to prevent the connecting arm 10 from bending under the action of gravity, because when there is no hanging plate 12 on the connecting arm 10, its fulcrum is at the output shaft of the servo motor 9.

[0033] As a preferred method, a ball 13 is provided between the hanging plate 12 and the arc-shaped track 6. After designing the ball 13, the friction between the hanging plate 12 and the arc-shaped track 6 is reduced during the movement of the moving seat 7 along the arc-shaped track 6. Since the arc-shaped track 6 is arc-shaped, only the ball 13 can be used, and wheels with directional movement (at least universal wheels) cannot be used. Compared with universal wheels, the ball 13 is more sensitive than universal wheels.

[0034] As a preferred method, it further includes a bottom plate 14. The bottom plate 14 is detachably installed on the surface of the hanging plate 12 facing the arc-shaped track 6. A preset distance is provided between the bottom plate 14 and the installation shaft 11. A first ball cavity 15 is provided on the side of the bottom plate 14 facing away from the arc-shaped track 6. A second ball cavity 16 matching the first ball cavity 15 is provided on the side of the hanging plate 12 facing the arc-shaped track 6. An opening A17 facing the arc-shaped track 6 is provided on the first ball cavity 15. The radius of the opening A17 is smaller than the radius of the ball 13. The distance from the opening A17 to the top of the first ball cavity 15 is smaller than the diameter of the ball 13. After such a setting, it is convenient to install the ball 13, such as Figure 3 , Figure 7 , Figure 8As shown, on one side of the hanging plate 12 facing the arc-shaped track 6, there are also screw holes 27, and the bottom plate 14 is also provided with through screw holes 27. During manufacturing, after the ball 13 is first placed into the first ball cavity 15, the bottom plate 14 is covered, and then bolts are screwed into the screw holes 27 on the hanging plate 12 and the screw holes 27 on the bottom plate 14, thereby locking the bottom plate 14 and the hanging plate 12 together.

[0035] As a preferred method, the ball 13 is made of iron, and it further includes a control chip. On the mounting shaft 11, between the arc-shaped track 6 and the moving seat 7, there is a mounting plate 26. On one side of the mounting plate 26 facing the arc-shaped track 6, there is an electromagnet 18. The control chip is signal-connected to the power switch of the electromagnet 18 and the servo motor 9. After such a setting, when the control chip controls the servo motor 9 to drive the moving seat 7 to move to a suitable position, the control chip transmits a signal to the power switch of the electromagnet 18, and the power switch makes the electromagnet 18 energized to generate magnetism, thereby attracting the ball 13 to prevent the ball 13 from rotating, thus playing a role in limiting. This role of limiting is very important; especially in the Figure 10 shown embodiment, the ball 13 being adsorbed by the electromagnet 18 can play a role in supporting the connecting arm 10, that is, preventing the connecting arm 10 from bending downward under the action of gravity and the gravity of the moving seat.

[0036] As a preferred method, as shown in Figure 5 and Figure 6 , on the bottom plate 14, away from the first ball cavity 15, there is a cylindrical cavity 19. The opening B17 of the cylindrical cavity 19 faces the hanging plate 12. On the bottom wall of the cylindrical cavity 19 on the bottom plate 14, there is a through hole 20. Inside the cylindrical cavity 19, there is a steel needle 21. The diameter of the steel needle 21 is smaller than the diameter of the through hole 20. Radially between the two ends of the steel needle 21, there are protrusions 23. Coaxially sleeved on the steel needle 21 between the protrusions 23 and the inner bottom wall of the cylindrical cavity 19 is a spring 22. After such a setting, when the electromagnet 18 generates suction, the end of the steel needle 21 can be made to abut against the arc-shaped track 6, thereby playing a further role in limiting. And after the electromagnet 18 is powered off and has no suction, the steel needle 21 retracts into the cylindrical cavity 19 under the action of the spring 22, thus not affecting the servo motor 9 to drive the moving seat 7 to move.

[0037] Among them, there are two classic design methods in this application. Among them, Figure 1 , Figure 2 , Figure 4 , Figure 9 is the design method where the outer wall B is used as the top wall of the bracket 1. In this method, the hanging plate 12 is very important, which is to hold the connecting arm 10 at the free end of the connecting arm 10. At the same time, the ball 13 is also particularly important. AndFigure 10 In the design method, the outer wall B is not the top wall of the bracket 1. At this time, it is very important whether the electromagnet 18 cooperates with the ball 13 or the electromagnet 18 cooperates with the steel needle 21, because when the free end of the connecting arm 10 moves to a preset position, it needs to be limited and fixed, so as to play a role in supporting the free end of the connecting arm 10.

[0038] As a preferred method, the outer wall B3 is the upper surface of the bracket 1, and the outer wall A2 is the left side wall or the right side wall of the bracket 1.

[0039] As a preferred method, the arc track 6 is provided with arc scale lines 24, the connecting arm 10 is fixedly provided with a camera 25, the camera 25 is signal-connected to the control chip, and the shooting direction of the camera 25 faces the arc scale lines 24. The arc scale lines 24 are arranged around the virtual circle array. The camera 25 can shoot the arc scale lines 24 and transmit them to the control chip to form a feedback adjustment, especially Figure 10 In the implementation method, the influence of the moment bending on the free end of the connecting arm 10 on the measurement result is very large. Therefore, it is necessary for the camera 25 to feedback the scene to the control chip, and the control chip controls the servo motor 9 to make a corrected rotation.
