Abstract
Description
Technical Field
[0001] This utility model relates to the field of production tools, and in particular to a fixture for inspecting the appearance of TV lenses. Background Technology
[0002] A TV lens, or television lens, is a lens specifically designed for television backlight systems and other lighting equipment. It is primarily used in the backlight systems of television backlights, advertising light boxes, panel lights, and other similar lighting devices. Through optical principles, it diffuses and homogenizes the light emitted from a light source, thereby improving lighting effects and enhancing visual comfort.
[0003] TV lenses may develop defects during the manufacturing process. These defects can be caused by a variety of factors, including manufacturing processes, material properties, injection molding processes, and optical characteristics. To prevent defective products from leaving the factory, in addition to strictly controlling process parameters and material quality, a dedicated inspection station is set up to manually identify defective TV lenses.
[0004] The current inspection method involves placing the TV lens against a green or white background and visually inspecting it manually under the factory's own lighting. This method is limited in its ability to identify appearance defects such as poor fogging and dust accumulation, resulting in a significant number of defective products leaving the factory and causing customer complaints. Furthermore, it requires inspectors to perform more thorough inspections, leading to decreased inspection efficiency and increased worker fatigue. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide a TV lens appearance inspection fixture. By placing the TV lens on an inspection fixture with light strips on the side for inspection, the product's fogging defects and dust defects are clearly visible, reducing the difficulty for workers to detect fogging defects and dust defects, thereby reducing the workers' energy consumption and improving inspection efficiency.
[0006] A TV lens appearance inspection fixture includes a base, a light strip mounting frame, and a light strip. The light strip mounting frame is fixed to the base and has a feeding notch. The light strip is arranged around the inner wall of the light strip mounting frame and fixed to the inner wall of the light strip mounting frame.
[0007] The TV lens appearance inspection fixture described in this utility model places the TV lens on an inspection fixture with light strips on the side for inspection, making the product's fogging and dust defects clearer, reducing the difficulty for workers to detect fogging and dust defects, thereby reducing the workers' energy consumption and improving inspection efficiency.
[0008] Furthermore, it also includes colorless glass, which is located within the space enclosed by the light strip mounting frame. The base has an inspection hole, and the colorless glass covers the inspection hole and is fixed to the base. Placing the TV lens on the bottom-hollowed glass further magnifies the product's fogging and dust defects, reducing the difficulty of inspection.
[0009] Furthermore, it also includes a glass limiting frame, which is located between the light strip mounting frame and the base. The bottom side of the glass limiting frame is fixed to the base and forms a glass placement groove. The inspection hole is located at the bottom of the glass placement groove, and the colorless glass mates with the glass placement groove. The glass limiting frame prevents the glass from shifting when the TV lens is moved, thus avoiding interference with the inspection process.
[0010] Furthermore, it also includes a light-shielding part that extends along the direction of the light strip. One side of the light-shielding part is fixed to the light strip mounting frame, and the other side extends towards the light strip until the light-shielding part covers the light strip. The light-shielding part prevents the light from the light strip from directly entering the eyes of the inspection workers, thereby reducing eye strain.
[0011] Furthermore, it also includes a guide section located at the material feeding notch. The bottom of the guide section is fixed to the base, and one side of the guide section is fixed to the light strip mounting frame. The guide section includes a guide slope that slopes from the inside of the light strip mounting frame to the outside. The guide section facilitates workers in quickly and easily pushing the inspected TV lens out of the inspection fixture, reducing inspection difficulty and increasing inspection efficiency.
[0012] Furthermore, the light strip mounting frame has a power cord notch through which the power cord passes and is electrically connected to the light strip. This power cord notch facilitates the installation of the light strip and prevents workers from touching the power cord during inspection.
[0013] Furthermore, it also includes a background panel, which is located within the space enclosed by the light strip mounting frame and fixed to the base. The background panel includes a black area and a white area. Setting up a background panel helps workers identify atomization defects and dust defects. Specifically, the black area of the background panel helps to clearly identify atomization defects, dust defects, and bubble defects, while the white area of the background panel helps to clearly identify black spot defects, discoloration defects, top burst defects, and pull-out defects.
[0014] Furthermore, it also includes a background plate, which is fixed to the lower side of the base and covers the inspection hole. The background plate covering the inspection hole includes a black area and a white area. Placing the background plate below the glass helps workers identify atomization defects and dust defects. Specifically, the black area of the background plate helps to clearly identify atomization defects, dust defects, and bubble defects, while the white area of the background plate helps to clearly identify black spot defects, discoloration defects, top burst defects, and pull burst defects.
[0015] Furthermore, the glass limiting frame is the same size and shape as the light strip mounting frame, and the glass limiting frame and the light strip mounting frame are integrally formed. Making the size and shape of the glass limiting frame the same as the light strip mounting frame maximizes the effective inspection range of the fixture and increases worker inspection efficiency.
[0016] Furthermore, the base is a colorless and transparent base, and the light strip mounting frame is a colorless and transparent light strip mounting frame. The use of a colorless and transparent mounting frame increases light transmission, which helps to amplify imperfections such as fogging and dust buildup in the product itself.
[0017] The beneficial effects of this application are as follows:
[0018] 1. Place the TV lens on an inspection fixture with light strips on the side for inspection. This will make the product's fogging and dust defects clearer, reduce the difficulty for workers to detect fogging and dust defects, thereby reducing the workers' energy consumption and improving inspection efficiency.
[0019] 2. Place the TV lens on the glass with a hollowed-out bottom to further magnify the product's fogging and dust defects, reducing the difficulty of inspection.
[0020] 3. Install a glass limiting frame to prevent the glass from shifting when the TV lens is moved, which would affect the inspection process.
[0021] 4. Install light shields to prevent the light from the light strips from shining directly into the eyes of the inspectors, thereby reducing eye strain.
[0022] 5. The guide section allows staff to easily and quickly push the inspected TV lens out of the inspection fixture, reducing inspection difficulty and increasing inspection efficiency.
[0023] 6. A power cord notch is provided to facilitate the installation of the light strips and prevent workers from touching the power cord during inspection.
[0024] 7. Setting up a background board with black and white areas helps workers identify atomization defects and dust defects. Specifically, the black area of the background board helps to clarify atomization defects, dust defects, and bubble defects, while the white area of the background board helps to clarify black spot defects, discoloration defects, top burst defects, and pull burst defects.
[0025] 8. Setting up a background board with black and white areas under the glass helps workers identify poor fogging and dust. Specifically, the black area of the background board helps to clarify poor fogging, dust, and bubble defects, while the white area of the background board helps to clarify black spot defects, discoloration defects, top burst defects, and pull burst defects.
[0026] 9. Make the size and shape of the glass limiting frame the same as the size and shape of the light strip mounting frame to maximize the effective range of the fixture for inspection and increase the inspection efficiency of workers.
[0027] 10. Use a colorless and transparent mounting frame to increase light transmission, which helps to magnify poor atomization and dust in the product itself.
