Description

Technical Field

[0001] This application belongs to the field of manufacturing technology of auxiliary components for lens inspection, specifically an optical inspection instrument mounting bracket. Background Technology

[0002] Optical inspection instruments are used to detect the properties of objects based on optical principles, playing a crucial role in the inspection of the light transmittance of lenses or glass lenses. They collect and analyze light signals through an optical system to obtain parameters such as the light transmittance, haze, and surface defects of glass, providing a scientific basis for the quality control of lenses or glass lenses.

[0003] Light receiving sensors and light sources are valuable instruments that need to be stored and preserved after each test. Users must register with the instrument administrator to retrieve them for the next use. Therefore, each time a lens or optical lens is tested, it is often necessary to measure the relative position of the light receiving sensor and the light source, and then install the light source, light receiving sensor, and fixture for fixing the lens or optical lens onto a frame. The installation itself is not complicated, but the relative position calibration between the light source and the light receiving sensor is cumbersome each time. Therefore, it is necessary to design a frame that already has the relative position of the light source, light receiving sensor, and fixture for fixing the glass fixed in place, so that the light source, lens or optical lens, and light receiving sensor can be directly installed when testing is required.

[0024] like Figure 1-5As shown, an optical inspection instrument mounting bracket includes a mounting plate 3 for mounting a light receiving sensor. An arc-shaped strip 6 is provided at the upper left end of the mounting plate 3. The arc-shaped strip 6 is circular in shape, and its inner arc surface is located on the side close to the mounting plate 3. A movable block 7 is provided on the upper part of the arc-shaped strip 6. The movable block 7 has a groove inside that fits the shape of the outer wall of the arc-shaped strip 6. A light source holder is provided on the inner arc surface of the movable block 7. A perforated plate 4 is fixedly connected to the mounting plate 3. The perforated plate 4 forms a preset angle with the horizontal plane and is perpendicular to the plane where the arc of the arc-shaped strip is located. The center of the circle where the arc of the arc-shaped strip 6 is located coincides with the center of the hole on the perforated plate. Lens holders 5 are arranged around the perforated position of the perforated plate 4.

[0025] In this embodiment, during use, the light source is mounted on the clamping member that holds the light source, and then the light receiving sensor is mounted on the mounting plate, so that the light emitted by the light source clamping member can pass through the center of the hole on the perforated plate 4 and shine on the light receiving sensor. Finally, the lens or lens is clamped by the lens holder 5, and the test can begin. During the test, pushing the moving block 7 to move on the arc strip 6 changes the angle at which the light source shines on the measured point on the glass.

[0026] As a preferred embodiment, the outer arc surface of the arc-shaped strip 6 is coaxially provided with a mounting groove 81. The mounting groove 81 is semi-circular in shape, and a rack 82 is fixedly connected to the inner wall of the mounting groove 81. The rack 82 is also semi-circular in shape, coaxial with the arc-shaped strip 6, and its teeth face the opening of the mounting groove 81. A rotating rod 83 is rotatably provided on the moving block 7, and a gear 84 is provided on the rotating rod 83 within the groove of the moving block 7, meshing with the rack 82. The meshing of the rack 82 and the gear enables uniform speed movement when the moving block 7 is pushed, facilitating control.

[0027] As a preferred embodiment, the opening of the mounting groove 81 is provided with a blocking structure, which is used to seal the mounting groove 81. This arrangement ensures that the mounting groove 81 is covered in areas where the moving block 7 does not pass, preventing dust and impurities from entering the mounting groove 81.

[0028] In a preferred embodiment, the blocking structure includes a stop block 852. A groove 851 is provided on the side wall of the mounting groove 81 on the outer side of the rack 82. The stop block 852 is slidably connected to the inner wall of the groove 851. The stop block 852 and the inner wall of the groove 851 are elastically connected by a spring 853. A control groove 854 is provided on the side of the stop block 852 facing away from the groove 851. A push plate 855 that cooperates with the control groove 854 is fixedly provided on the inner wall of the moving block 7. When the moving block 7 moves, the push plate 855 on the moving block 7 pushes the push plate stop block 853 away, thus ensuring that the setting of the stop block 852 does not affect the meshing of the gear 84 and the rack 82 within the mounting groove 81. When the push plate 855 contacts the stop block 852, the side wall of the stop block 852 that is perpendicular to the moving direction of the moving block 7 is an inclined surface, which is the control groove 854, so that the push plate 855 can squeeze the stop block 852 into the slide groove 851.

[0029] As a preferred embodiment, the movable block 7 is equipped with a braking device for braking the movable block 7. By providing the braking device, after the movable block 7 moves to a designated position (the position where the inspector deems it necessary to stop the movable block 7), the movable block 7 can be fixed relative to the arc-shaped strip 6.

[0030] In a preferred embodiment, the braking device includes an airbag 92. The movable block 7 contains a pressure chamber 91. The airbag 92 is fixedly connected to the inner wall of the groove, and the interior of the airbag 92 communicates with the interior of the pressure chamber 91. A sliding plate 93 is piston-connected to the inner wall of the pressure chamber 91. A threaded rod 94 is rotatably connected to the right end of the sliding plate 93. The threaded rod 94 passes through the movable block 7 and is threadedly connected to the inner wall of the movable block 7. A positioning hole 95 is provided on the outer wall of the arc-shaped strip 6 along the movement path of the airbag 92. After the movable block 7 is adjusted to a suitable position, the user rotates the threaded rod 94, pushing the sliding plate 93 towards the airbag 92, thereby pushing the gas in the pressure chamber 91 into the airbag 92, causing the airbag 92 to inflate. After inflating, the airbag 92 fits tightly against the positioning hole 95. The deformation of the airbag 92 during inflating creates a protrusion that matches the positioning hole 95, thus achieving a braking effect. This method of braking using the airbag 92 does not damage the surface of the arc-shaped strip 6.

[0031] As a preferred embodiment, the number of the stops 852 is multiple, and the multiple stops 852 are arranged in two groups. The two groups of stops 852 are mirror images of each other in the front-back direction, and the multiple groups of stops 852 are arranged in a linear array along the arc corresponding to the outer arc surface of the arc strip 6.

[0032] Specifically, the groove and the side wall of the air pressure chamber 91 are provided with holes that allow the interior of the air pressure chamber 91 to communicate with the interior of the airbag.

[0033] As a preferred embodiment, the right end of the arc-shaped strip 6 is fixedly connected to a mounting rod 2, the lower end of the mounting rod 2 is fixedly connected to a base plate 1, and the middle part of the mounting rod 2 is fixedly connected to a mounting plate 3. The mounting plate 3 facilitates placement.

[0034] Specifically, the mounting plate 3 is horizontally positioned, and one end of the perforated plate 4 is connected to the mounting plate 3; a fixing block 10 is provided on the upper part of the mounting rod 2, and the fixing block 10 has an inclined surface 101 on the side facing the arc-shaped strip 6, with one end of the arc-shaped strip 6 connected to the inclined surface 101. This arrangement ensures that the light emitted by the light source held by the light source holder illuminates the lens being inspected at an angle, facilitating observation and adjustment by the inspector.
