Description

Technical Field

[0001] This utility model relates to the field of filter manufacturing technology, and in particular to a filter rotation mechanism. Background Technology

[0002] Optical filters are used to select the desired wavelength of radiation. A common characteristic of all filters is that no filter can make the image of a celestial object brighter, because all filters absorb certain wavelengths, thus making the object darker. Filters come in many types, shapes, and specifications. Types include absorption filters and interference filters; shapes include circles, squares, and rectangles; and specifications, taking quartz as an example, include filters with lengths ranging from 3-300 mm and thicknesses from 0.5-20 mm. After production, the surface of the filter needs to be inspected to avoid light spots and scratches. Therefore, the filter needs to be inspected and observed from multiple angles.

[0003] Chinese utility model patent document CN220381025U discloses a device for testing colored glass filters for consumer electronics, including a support base and a support frame. The support frame is installed on the upper right end of the support base, and a testing mechanism for testing colored glass filters for consumer electronics is provided on the upper end of the support base. The testing mechanism includes a first support plate, a second support plate, and a testing camera. The first and second support plates are respectively installed on the upper end of the support base, and the testing camera is installed on the upper end of the support frame. This testing device uses clamping plates to support the edges of colored glass filters of different sizes. The clamping plates drive the colored glass filters to automatically flip and test. It can not only support and test colored glass filters of different sizes, but also realize the automatic flipping and testing of the front and back of the colored glass filters. After testing, the colored glass filters are removed from the clamping plates with the assistance of a telescopic rod, which improves the efficiency and convenience of testing colored glass filters.

[0004] Although the aforementioned consumer electronics colored glass filter inspection device can solve the corresponding technical problems, different types of filters not only vary in width but also in thickness. However, its clamping plates one and two can only clamp and fix filters of different widths, making it difficult to clamp filters of different thicknesses and impossible to adjust the clamping thickness. Therefore, when inspecting filters of different thicknesses, it is impossible to fix the filters well, and it is also impossible to observe and inspect the filters from angles other than horizontal observation. This reduces the applicability of the device. Therefore, we propose a filter rotation mechanism. Utility Model Content

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component. To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Please see Figures 1-3 This utility model provides a filter rotation mechanism, including: a support assembly 1, two symmetrical clamping assemblies 2 for clamping and fixing filters, an adjusting assembly 3 for driving the two clamping assemblies 2 to move synchronously towards or away from each other, and a rotating assembly 4 for driving the clamping assemblies 2 and the adjusting assembly 3 to rotate synchronously. The clamping assemblies 2 are located in the inner cavity of the support assembly 1, the adjusting assembly 3 is located on the rear side of the clamping assemblies 2, and the rotating assembly 4 is located on the support assembly 1. The clamping assembly 2 includes a side housing 21. The two side housings 21 have an open structure on their facing side and front side. The inner cavity of the side housing 21 is horizontally movably connected to a clamping plate 22. The top of the clamping plate 22 is rotatably connected to a stud 23 through a bearing. The top of the stud 23 movably extends to the top of the side housing 21 and is fixedly connected to a knob 24. The surface of the stud 23 is threadedly connected to the through-hole of the side housing 21. The rear side of the clamping plate 22 contacts the inner wall surface of the side housing 21.

[0028] The support assembly 1 includes a base plate 11, with support plates 12 vertically fixedly connected to both sides of the top of the base plate 11. The base plate 11 and the two support plates 12 form a U-shaped frame. Two side shells 21 are located between the two support plates 12. The support assembly 1 can provide a support foundation for the filter rotation mechanism.

[0029] Rubber gaskets 25 are glued to the side and bottom of the inner wall of the side housing 21 and the bottom of the clamping plate 22. The rubber gaskets 25 can increase the friction between the side housing 21, the clamping plate 22 and the filter, improve the clamping stability of the side housing 21 and the clamping plate 22, and prevent the side housing 21 and the clamping plate 22 from directly contacting the filter and causing wear on the surface of the filter.

[0030] The adjustable distance assembly 3 includes a rear housing 31 arranged parallel to the base plate 11. The front side of the rear housing 31 has an open structure. A first motor 32 is installed on one side of the rear housing 31. The output shaft of the first motor 32 passes through the inner cavity of the rear housing 31 and is fixedly connected to a bidirectional screw 33. A screw sleeve 34 is threaded on both sides of the surface of the bidirectional screw 33. The screw sleeve 34 is arranged in a one-to-one correspondence with the side housing 21, and one side of the screw sleeve 34 is fixedly connected to the corresponding side housing 21. When the first motor 32 is started, the output shaft of the first motor 32 can drive the two side housings 21 to move towards each other or away from each other, thereby realizing the clamping and fixing of filters of different widths.

[0031] The surface of the threaded sleeve 34 is slidably connected to the inner wall of the rear housing 31, which can limit the threaded sleeve 34 and effectively prevent the threaded sleeve 34 from rotating with the bidirectional screw 33, thereby improving the stability of the threaded sleeve 34 when it moves horizontally along the axial direction of the bidirectional screw 33.

[0032] The rotating assembly 4 includes two side plates 41 fixedly connected to the front side of the rear housing 31. Two side housings 21 are located between the two side plates 41. Movable columns 42 are fixedly connected to the opposite sides of the two side plates 41. A second motor 43 is installed on one of the support plates 12. The output shaft of the second motor 43 passes through one side of the support plate 12 and is fixedly connected to one of the movable columns 42. One end of the other movable column 42 is rotatably connected to the other support plate 12 through a bearing. When the second motor 43 is started, the output shaft of the second motor 43 can drive the adjusting assembly 3 and the clamping assembly 2 to rotate synchronously, thereby enabling the rotation and flipping operation of the filter clamped and fixed by the clamping assembly 2.

[0033] The central axis of the movable column 42 and the output shaft of the second motor 43 are on the same straight line.

[0034] Among them, a protruding post 44 is fixedly connected to the side of the side plate 41 near the corresponding support plate 12. A ball bearing 45 is movably embedded at one end of the protruding post 44. An annular groove 46 for the ball bearing 45 to roll is opened on the side of the support plate 12 near the side plate 41. When the adjusting assembly 3 rotates, it can drive the side plate 41, the protruding post 44 and the ball bearing 45 to rotate synchronously, so that the ball bearing 45 rolls in the inner cavity of the annular groove 46, thereby improving the stability of the side plate 41, the adjusting assembly 3 and the clamping assembly 2 when rotating.

[0035] It should be noted that the second motor 43 mentioned above is a stepper motor, which can realize the functions of stopping at any position and rotating in both directions.

[0036] The working principle of this utility model is as follows: By rotating the knob 24, the rotating knob 24 drives the stud 23 to rotate at the through-hole of the side housing 21. Under the action of the thread, the stud 23 drives the clamping plate 22 to move up or down in the inner cavity of the side housing 21, so that the distance between the clamping plate 22 and the bottom of the inner wall of the side housing 21 can be adjusted according to the thickness of the filter. After the clamping plate 22 is adjusted to the required position, one side of the filter is inserted into the inner cavity of one of the side housings 21, with the filter located below the clamping plate 22. The first motor 32 is started, and the output shaft of the first motor 32 drives the bidirectional screw 33 to rotate. Under the action of the thread, the bidirectional screw 33 drives the two threaded sleeves 34 on its surface to move towards each other. The threaded sleeves 34 drive the opposite... The corresponding side housing 21 and clamping plate 22 move synchronously, thereby causing the two side housings 21 to move towards each other and clamp and fix the two sides of the filter, so that the two sides, top surface and ground of the filter are in contact with the surface of the corresponding rubber pad 25, thus completing the fixing operation of the filter; start the second motor 43, the output shaft of the second motor 43 drives the movable column 42, side plate 41, protruding column 44, ball 45, adjusting assembly 3, clamping assembly 2 and filter to rotate synchronously around the movable column 42 as the center, and the ball 45 rolls in the inner cavity of the annular groove 46, thereby realizing the rotation and flipping operation of the filter. By rotating the filter at different angles, the filter can be detected at different angles.

[0037] This utility model discloses a filter rotation mechanism. By adjusting the distance between two clamping components 2 through an adjustable distance assembly, the two side housings 21 can clamp and fix filters of different widths and sizes. By rotating the stud 23, the distance between the clamping plate 22 and the bottom of the inner wall of the side housing 21 can be adjusted, thereby enabling the side housing 21 and clamping plate 22 to clamp and fix filters of different thicknesses, thus improving the applicability of the filter rotation mechanism. This filter rotation mechanism can also drive the two clamping components 2 to move synchronously towards or away from each other through the adjustable distance assembly 3, avoiding the use of springs to provide clamping force, which helps to improve the clamping stability and service life of the clamping components 2. At the same time, this filter rotation mechanism can further use a second motor 43 to adjust the test angle of the filter, and the detection of multiple different angles can ensure the accuracy of the detection.

This utility model only adopts the functions disclosed in the existing technology of the above components and does not involve any improvement to them. It will not be described in detail here.
