[0003] According to the publicly disclosed concentricity detection device (publication number: CN217504719U), in the above application, since the above concentricity detection unit is electrically connected to the above charge-coupled device camera, the concentricity of the workpiece to be detected in the above image can be detected without contacting the workpiece to be detected. Thus, the concentricity detection device can improve the accuracy of concentricity detection.

[0004] The concentricity detection of the lens requires two or more groups of lenses to be stacked together for testing. Although this device can detect the concentricity without contacting the workpiece to be detected, it lacks a device for positioning the lens, and the uneven placement of the lens will also affect the accuracy of concentricity detection.

Specific embodiments

[0024] As Figures 1 - 5 shown, the present utility model provides a technical solution: an optical lens concentricity detection device, including a base plate 1, a column 2 is fixedly installed on the top of the base plate 1, and an industrial camera 3 is fixedly installed at one end of the column 2 away from the base plate 1. An inclined groove 4 is opened on the base plate 1, and the inclined groove 4 can be used to provide guidance for the positioning rod 55. A positioning mechanism 5 is arranged on the base plate 1. By setting the positioning mechanism 5, multiple groups of lenses can be neatly positioned on the base plate 1, improving the accuracy of the lens concentricity detection. A protection mechanism 6 for protecting the industrial camera 3 is arranged on the column 2. By setting the protection mechanism 6, the lens of the industrial camera 3 can be protected, preventing the lens of the industrial camera 3 from being impacted when idle, and at the same time, preventing dust from adhering to the lens of the industrial camera 3.

[0025] The above-mentioned positioning mechanism 5 includes a sliding rod 51, a pressing plate 52, a connecting rod 53, a sliding groove 54, a positioning rod 55, and a spring 56; the sliding rod 51 is slidably connected to the bottom of the base plate 1, a sliding groove 54 is opened on the sliding rod 51, and a positioning rod 55 is slidably connected to the inner wall of the inclined groove 4. Four mutually approaching positioning rods 55 can be used to position the lenses on the base plate 1, enabling multiple groups of lenses to be neatly placed on the base plate 1, thereby improving the accuracy of the lens concentricity detection. The outer wall of the positioning rod 55 is attached to the inner wall of the sliding groove 54. When the two sliding rods 51 slide synchronously and approach each other on the inner wall of the base plate 1, the sliding groove 54 opened on the sliding rod 51 will squeeze the positioning rod 55, causing the four positioning rods 55 to slide synchronously and approach each other on the inner wall of the inclined groove 4. The pressing plate 52 is slidably connected to the outer wall of the column 2, a spring 56 is fixedly installed at the bottom of the pressing plate 52, and one end of the spring 56 away from the pressing plate 52 is fixedly installed on the top of the base plate 1. Press the pressing plate 52 downward to make the pressing plate 52 slide downward on the outer wall of the column 2 and compress the spring 56. When the pressing plate 52 is released, the elasticity of the spring 56 can drive the pressing plate 52 to slide upward and reset on the outer wall of the column 2. One end of the connecting rod 53 is hinged to the bottom of the pressing plate 52, and the other end of the connecting rod 53 is hinged to the top of the sliding rod 51. When the pressing plate 52 slides downward on the outer wall of the column 2, it will push the two connecting rods 53, causing the two connecting rods 53 to respectively push the two sliding rods 51, making the two sliding rods 51 slide synchronously and approach each other on the inner wall of the base plate 1.

[0026] The above-mentioned protection mechanism 6 includes a support rod 61, a swing rod 62, a protective cover 63, a limit groove 64, and a push rod 65; one end of the support rod 61 is fixedly installed on the outer wall of the column 2, the other end of the support rod 61 is hinged with a swing rod 62, and a protective cover 63 is fixedly installed at the end of the swing rod 62 away from the support rod 61. By rotating the swing rod 62, the protective cover 63 can be driven to cover the lens of the industrial camera 3, preventing the lens of the industrial camera 3 from being impacted when it is idle, and at the same time, preventing dust from adhering to the lens of the industrial camera 3. A limit groove 64 is provided on the swing rod 62, a push rod 65 is fixedly installed on the top of the pressing plate 52, and the outer wall of the push rod 65 fits on the inner wall of the limit groove 64. When the pressing plate 52 slides on the outer wall of the column 2, it will drive the push rod 65 to fit and move on the inner wall of the limit groove 64 and squeeze the swing rod 62, causing the swing rod 62 to rotate on the outer wall of the support rod 61.

[0027] Working principle: First, stack multiple lenses to be detected on the bottom plate 1, and then press down the pressing plate 52, so that the pressing plate 52 slides downward on the outer wall of the column 2 and compresses the spring 56. At the same time, the pressing plate 52 will push two groups of connecting rods 53, causing the two groups of connecting rods 53 to push two groups of sliding rods 51 respectively, so that the two groups of sliding rods 51 slide synchronously and approach each other on the inner wall of the bottom plate 1. At this time, the chute 54 provided on the sliding rod 51 will squeeze the positioning rod 55, causing the four groups of positioning rods 55 to slide synchronously and approach each other on the inner wall of the inclined groove 4. At this time, the four groups of mutually approaching positioning rods 55 can be used to position the lenses on the bottom plate 1, so that multiple groups of lenses can be neatly placed on the bottom plate 1, thereby improving the accuracy of lens concentricity detection.

[0028] When the pressing plate 52 slides downward on the outer wall of the column 2, it will drive the push rod 65 to move downward synchronously. At this time, the push rod 65 will fit and move on the inner wall of the limit groove 64 and squeeze the swing rod 62 downward, causing the swing rod 62 to rotate on the outer wall of the support rod 61. At the same time, the swing rod 62 will drive the protective cover 63 to gradually move away from the industrial camera 3, so that the protective cover 63 can release the protection of the industrial camera 3, so that the industrial camera 3 can take pictures of the lens. When the pressing plate 52 is released, the elasticity of the spring 56 can drive the pressing plate 52 to slide upward and reset on the outer wall of the column 2. At the same time, the pressing plate 52 will drive the push rod 65 to move upward synchronously. At this time, the push rod 65 will fit and move on the inner wall of the limit groove 64 and squeeze the swing rod 62 upward, causing the swing rod 62 to rotate on the outer wall of the support rod 61. At the same time, the swing rod 62 will drive the protective cover 63 to gradually approach the industrial camera 3, so that the protective cover 63 can cover the lens of the industrial camera 3. At this time, the protective cover 63 can be used to protect the lens of the industrial camera 3, preventing the lens of the industrial camera 3 from being impacted when it is idle, and at the same time, preventing dust from adhering to the lens of the industrial camera 3.

[0029] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
