Description

Technical Field

[0001] The utility model relates to the technical field of lens measurement, in particular to an appearance inspection machine for finished camera lens products. Background Art

[0002] Camera lens inspection machines are automated devices specifically designed to detect defects in mobile phone camera lenses. They can replace manual inspections and offer significantly higher efficiency. These machines typically feature proprietary lenses and lighting solutions, as well as highly efficient inspection algorithms, capable of detecting subtle defects such as light dirt, film delamination, black spots, and scratches.

[0003] In the existing lens thickness measurement technology, the center positions of the upper and lower spherical surfaces of the lens need to be adjusted to obtain an accurate thickness value. However, when measuring the next lens, since the centers of the front and rear lenses are different, the center of the lens will be offset after being placed, resulting in inaccurate lens thickness measurement. However, the existing detection machine is inconvenient to adjust and has great detection limitations. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides an appearance inspection machine for finished camera lenses, which solves the problem that the center of the lens is offset, resulting in inaccurate lens thickness measurement.

[0006] The detection component includes a sleeve column connected to the inner arc surface of the through slot, the interior of the sleeve column is sleeved with an axle rod, the top of the outer arc surface of the axle rod is connected with a floating shaft, one side of the floating shaft is adapted to the sensor, a strip hole is opened in the middle of the outer arc surface of the sleeve column, and the inner arc surface of the strip hole is connected with a connecting pin.

[0007] Optionally, the number of the floating shafts is two and they are distributed in a mirror-symmetrical manner, wherein a first spring is fixedly mounted on the inner arc surface of one of the floating shafts, and one end of the first spring is movably overlapped on the connecting pin.

[0008] Optionally, a spring retaining ring is fixedly installed on the lower surface of the sleeve column, and a second spring is fixedly installed on the upper surface of the spring retaining ring. One end of the second spring is movably overlapped on the surface of the connecting pin. By mobilizing the second spring on the top of the sleeve column, the upper connecting pin will be squeezed and moved upward in the bar hole during the upward movement of the second spring, so that the first spring synchronously drives the floating shaft to move upward or downward. Therefore, slight position deviations will be captured by the sensor, thereby finding and determining the position of the worn and damaged lens, thereby improving detection accuracy.

[0009] Optionally, a detection probe is fixedly installed on the end of the shaft away from the floating shaft, and extension parts are provided at the bottom of both sides of the connecting support. Adjustment components are fixedly installed on both sides of the back of the extension parts, and the adjustment components include an L-shaped coupling fixedly installed on the back of the extension parts.

[0010] Optionally, one side surface of the L-shaped coupling is movably connected with an adjustment knob, the inner side wall of the L-shaped coupling is movably connected with a rotating part, a front end of one side of the rotating part is provided with a bearing part, and the upper surface of the bearing part is movably connected with a fine-tuning platform.

[0012] The utility model provides a camera lens finished product appearance inspection machine, which has the following beneficial effects:

[0013] By mobilizing the second spring on the top of the sleeve column, the upper connecting pin will be squeezed and moved upward in the bar hole during the upward movement of the second spring, so that the first spring will synchronously drive the floating shaft to move upward or downward. Therefore, slight position deviations will be captured by the sensor, thereby finding and determining the location of the worn and damaged lens, thereby improving detection accuracy.

There are two floating shafts 603, which are distributed in a mirror-symmetrical manner. A first spring 606 is fixedly installed on the inner arc surface of one of the floating shafts 603, and one end of the first spring 606 is movably overlapped on the connecting pin 605. A spring retaining ring 607 is fixedly installed on the lower surface of the sleeve column 601, and a second spring 608 is fixedly installed on the upper surface of the spring retaining ring 607, and one end of the second spring 608 is movably overlapped on the surface of the connecting pin 605.

[0023] By mobilizing the second spring 608 on the top of the socket column 601, the upper connecting pin 605 will be squeezed and moved upward in the bar hole 604 during the upward movement of the second spring 608, so that the first spring 606 will synchronously drive the floating shaft 603 to move upward or downward. Therefore, slight position deviations will be captured by the sensor 4, thereby finding and determining the position of the worn and damaged lens, thereby improving the detection accuracy.

[0024] A detection probe 609 is fixedly installed on one end of the shaft 602 away from the floating shaft 603, and an extension part 7 is provided at the bottom of both sides of the connecting support 3. Adjustment components 8 are fixedly installed on both sides of the back of the extension part 7. The adjustment component 8 includes an L-shaped coupling 801 fixedly installed on the back of the extension part 7. One side surface of the L-shaped coupling 801 is movably connected with an adjustment knob. The inner side wall of the L-shaped coupling 801 is movably connected with a rotating part 802. A bearing part 803 is provided at the front end of one side of the rotating part 802. The upper surface of the bearing part 803 is movably connected with a fine-tuning platform 9.

A bearing surface 12 is provided in the middle of one side surface of the clamping claw 11. One side of the bearing surface 12 is movably connected with a lens body 13.

[0025] The L-shaped coupling 801 on the adjustment component 8 can assist in fine-tuning the lens body 13 on the surface of the platform 9, making it easier to cooperate with the irradiation part and the photo detection part for detection, and making adjustment more convenient during detection.

[0026] In the present invention, the working steps of the device are as follows:

[0027] The detection fixture 1 is fixedly installed on the detection machine to form a whole. The movable plate 2 is slidably connected to the front end of the detection fixture 1, so that the components connected on the front can achieve the effect of moving left and right. Before starting work, the lens body 13 is fixed and placed in the empty groove on the surface of the fine-tuning platform 9. Then the clamping jaws 11 on both sides are close to each other in the sliding grooves 10 at both ends. When the center position of the lens is not determined, it can be clamped. When starting work, the detection component 6 is controlled to move from left to right. When the detection probe 609 contacts the lens body 13, the detection is started. First, the center point of the lens is confirmed, and the scanning program is performed on the program. The scanning path obtains XY to find the lowest and highest mirror positions, thereby determining the center position, and the moving distance of the clamping jaw 11 is pushed unilaterally, and the clamped lens body 13 is fine-tuned to perform position correction. The shaft 602 at the top of the detection probe 609 is connected through the socket column 601, so when a slight scratch or bump is detected, the second spring 608 at the top of the socket column 601 can be mobilized. During the upward movement of the second spring 608, the upper connecting pin 605 will be squeezed to move upward in the bar hole 604, so that the first spring 606 will synchronously drive the floating shaft 603 to move upward or downward. Therefore, slight position deviations will be captured by the sensor 4. Since the position of the floating shaft 603 has been recorded at the beginning, the floating changes will be recorded, so as to find and determine the position of the lens wear and tear, thereby improving the detection accuracy. The L-shaped coupling 801 on the adjustment component 8 can assist in fine-tuning the lens body 13 on the surface of the platform 9, which is convenient for cooperation with the irradiation part and the photo detection part, and is more convenient for adjustment during detection.
