[0036] The following combines the attached Figures 1 - 7Further details of this application will be described below.

[0037] An embodiment of this application discloses a lens concentricity detection device.

[0038] Refer to Figure 1 、 Figure 2 、 Figure 3 A lens concentricity detection device includes a detector body 1 for lens detection and a refraction plate 2 for refracting light sources. The refraction plate 2 is fixedly connected to a back plate 3 on one side. A circular base plate 6 is rotatably arranged on the upper part of the back plate 3. The circular base plate 6 is fixedly and penetratingly arranged on the outer surface of the upper part of the movable column 41. A plurality of through holes are provided on the upper surface of the circular base plate 6, and a lamp 7 is clamped in each of the plurality of through holes. The diameter of the through hole is the same as the diameter of the lamp 7. The plurality of lamps 7 arranged in an array can be set according to needs. A power supply 9 is arranged on the upper part of the refraction plate 2, and the power supply 9 can be separately clamped and electrified with each of the plurality of lamps 7. A stabilizing plate 12 is fixedly arranged at the connection part between the lower part of the power supply 9 and the lamp 7, and the stabilizing plate 12 is fixedly connected to one side of the detector body 1. The side of the stabilizing plate 12 away from the power supply 9 is fixedly connected to a dust-proof plate 8. The lower surface of the middle part of the dust-proof plate 8 is rotatably connected to the upper surface of the movable column 41. A plurality of grooves are arranged on the outer circle of the dust-proof plate 8 according to the number of the lamps 7 to protect the power connection terminals of the lamps 7.

[0039] It should be noted that the detector body 1, the refraction plate 2, the power supply 9, and the lamp 7 in the above device are all prior arts, and their structural principles will not be elaborated here. And this device also needs to be connected to a PC or a PLC controller. Since they are all prior arts, they will not be elaborated here.

[0040] The refraction plate 2 can refract the light source emitted by the lamp 7 into the detector body 1 to perform light detection on the lens concentricity. The circular base plate 6 can rotate and replace the lamp 7 according to needs, rotate the required lamp 7 below the power supply 9, and then the power supply 9 is docked with the lamp 7 to make the lamp 7 energized. The dust-proof plate 8 can effectively protect the power connection terminals of the lamp 7, and the stabilizing plate 12 can stabilize the power supply 9, so that the power supply 9 can be docked with the lamp 7 and ensure that the connection between the lamp 7 and the power supply 9 will not be unstable due to shaking or other situations during docking, resulting in deviation of the detection result due to unstable light source.

[0041] Refer to Figure 3 、 Figure 4, on the side of the backplane 3 away from the stabilizing plate 12, a rotation and replacement mechanism 4 is provided. The rotation and replacement mechanism 4 includes a movable column 41 that movably penetrates through the middle of the upper surface and the middle of the lower surface of the backplane 3. The outer surface of the lower part of the movable column 41 is rotatably connected to the inner surface of the rotating rocker 42. The lower surface of the rotating rocker 42 is rotatably connected to the upper surface of the bottom plate of the backplane 3. The lower part of the rotating rocker 42 away from the inclined slot 47 is rotatably connected to the upper surface of the connecting rod 13. The surface of the connecting rod 13 away from the rotating rocker 42 is fixedly connected to the surface of the extending end of the electric push rod 10. The electric push rod 10 is fixedly arranged on the upper part of the L-shaped fixing plate 11 through a fixing seat, and the L-shaped fixing plate 11 is fixedly connected to the detector body 1.

[0042] Refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 , one side of the upper surface of the rotating rocker 42 is fixedly connected to the lower surface of the support column 45. The upper surface of the support column 45 is rotatably connected to one side of the pawl 46. A torsion spring is arranged at the connection between the support column 45 and the pawl 46, which can help the pawl 46 to reset. The upper surface of the rotating rocker 42 is rotatably connected to the lower surface of the power ring 43. The inner surface of the power ring 43 is fixedly connected to the outer surface of the movable column 41. A number of inclined slots 47 are provided in a circle on the outside of the power ring 43, and a number of inclined slots 47 can be engaged with the pawl 46. A limiting ring 44 is provided on the upper part of the power ring 43. The inner surface of the limiting ring 44 is fixedly connected to the outer surface of the movable column 41. A number of limiting slots 48 are provided in a circle on the outside of the limiting ring 44. One side of the limiting slot 48 is engaged with the retractable limiting push rod 49. A spring is arranged inside the limiting push rod 49, which can help the limiting push rod 49 to limit and release the limiting slot 48. The surface of the limiting push rod 49 away from the movable column 41 is fixedly connected to one side surface of the T-shaped plate 5. The upper surface of the T-shaped plate 5 is fixedly connected to one side surface of the top plate of the backplane 3.

[0043] It should be noted that the number of the inclined slots 47 and the limiting slots 48 is the same as the number of the lamps 7, and the positions where the inclined slots 47 and the limiting slots 48 are provided are the same as the positions where the lamps 7 are arranged, so that the intermittent rotation distance of the inclined slots 47 and the limiting slots 48 is exactly the moving distance for replacing the lamp 7 connected to the power supply 9.

[0044] The torsion spring arranged at the connection between the support column 45 and the pawl 46 can move along the side wall of the power ring 43 after the pawl 46 is pushed by the support column 45 to disengage from the inclined slot 47 until it reaches the next external inclined slot 47. Under the action of the torsion spring, the pawl 46 can be inserted into the inclined slot 47, and then drive the inclined slot 47 and the power ring 43 to rotate.

[0045] A spring is provided inside the limit push rod 49, which can compress and retract the protruding end of the limit push rod 49 when the limit slot 48 rotates. When reaching the next limit slot 48, the protruding end of the limit push rod 49 is pushed out with the help of the spring to limit the limit ring 44. When the electric push rod 10 pushes the connecting rod 13 to move, the connecting rod 13 can push the rotating rocker 42 to rotate around the movable column 41, thereby driving the support column 45 and the pawl 46 to move. And through the support provided by the support column 45 for the pawl 46 to disengage from the inclined slot 47, the pawl 46 can disengage from the inclined slot 47 when moving. Since both the power ring 43 and the limit ring 44 are fixedly connected to the movable column 41, and the limit push rod 49 is snap-fitted and limited with the limit slot 48 opened on the outer circle of the limit ring 44, when the pawl 46 moves, the inclined slot 47 will not move with the pawl 46. Therefore, the pawl 46 can be separated from the inclined slot 47, and when the pawl 46 moves to the next inclined slot 47, it can be snap-fitted with the inclined slot 47 under the action of the torsion spring. Then, under the action of the electric push rod 10, the power ring 43 is pulled back, thereby separating the limit push rod 49 from the limit slot 48, so that the movable column 41 drives the circular bottom plate 6 fixedly connected thereto to rotate together. Immediately, the lamp 7 to be replaced will be rotated to the lower part of the power supply 9.

[0046] The implementation principle of the lens concentricity detection device in the embodiment of the present application is as follows: When the lens concentricity detects that another light source needs to be replaced for detection, the controller is turned on to control the protruding end of the electric push rod 10 to push out and drive the connecting rod 13 to move, thereby driving the rotating rocker 42 to rotate around the movable column 41, and then driving the pawl 46 to move, so as to be separated from the inclined slot 47. Then, when the pawl 46 moves to the next inclined slot 47, it is snap-fitted with the next inclined slot 47. Then, under the retracting and pulling action of the electric push rod 10, the power ring 43 is driven to rotate, thereby driving the movable column 41 and the limit ring 44 to rotate, separating the limit push rod 49 from the limit slot 48. At the same time, the rotation of the movable column 41 will drive the circular bottom plate 6 fixedly connected thereto to rotate together, thereby rotating the lamp 7 snap-fitted with the circular bottom plate 6 towards the power supply 9. When the limit push rod 49 is snap-fitted with the next limit slot 48, it means that the movable column 41 has also rotated the lamp 7 to the lower part of the power supply 9 and made an electrical connection with the power supply 9. And this process is repeated until the required light source is replaced.

[0047] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
