Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to an automatic coating fixture for LED light sources. Background Technology

[0002] The coating process for LED light sources is a key step in the manufacturing process. It mainly involves covering the surface of LED chips or package structures with specific functional materials to achieve core purposes such as protection, optical control, and color conversion.

Limiting and fixing components 32 are provided on both the left and right sides of the flexible protective component 31. A support plate 33 is provided at the rear end of the limiting and fixing components 32. The positioning mechanism 2 includes an L-shaped positioning component 21. Rectangular protrusions are provided on both the left and right sides of the support plate 33. A corresponding slot for the support plate 33 is provided on the inner side of the L-shaped positioning component 21. The rear end of the flexible protective component 31 is connected to the front end of the support plate 33 by bolt threads.

[0023] In this embodiment, rectangular protrusions are provided on the left and right sides of the support plate 33, and the inner side of the L-shaped positioning member 21 is provided with a corresponding slot for the support plate 33. The flexible protective member 31 is connected to the support plate 33 by bolt threads. The flexible protective member 31 is made of silicone.

The limiting and fixing member 32 can fix the support plate 33 in a mirror image to prevent the support plate 33 from falling out. When the L-shaped positioning member 21 positions the LED light source, the flexible protective member 31 and the spring at the rear end of the support plate 33 can protect the LED light source and prevent it from being damaged during positioning. Through the cooperation of the above parts, the LED light source can be protected from damage.

[0024] Working principle: As shown in Figure 1-4, by rotating the first fixing block 12 and the second fixing block 13, the LED light source can be adjusted. The roller 24 is fixed with a fixed cover at its lower end. The L-shaped positioning piece 21 is connected and fixed to the roller 24 through the fixed cover. The movement of the slider 22 can be limited by the limiting piece 29 at the front end of the slide rail 23 to prevent it from derailing. The lower end of the connecting piece 26 is provided with a fixed shaft. By rotating the fixed shaft on the connecting piece 26, the connecting piece 26 is rotated, which in turn drives the slider 22 to move through the connecting rod 25. After the LED light source is placed, the slider 22 moves inward, so that the roller 24 contacts the LED light source, which in turn drives the L-shaped positioning piece 21 to rotate, and the torsion spring 27 rotates together. The light source is positioned by the L-shaped positioning. When the positioning is released, the torsion spring 27 loses the external force and rotates back, so that the L-shaped positioning piece 21 returns to its original position. By pushing the limiting piece 29, the connecting piece 26 can be fixed to prevent the connecting piece 26 from derailing after the L-shaped positioning piece 21 has positioned the LED light source. If the LED light source is moved again, it may become loose, leading to inaccurate positioning. The limiting and fixing component 32 can fix the support plate 33 to prevent it from falling out. When the L-shaped positioning component 21 positions the LED light source, the flexible protective component 31 and the spring at the rear end of the support plate 33 can protect the LED light source to prevent damage during positioning, avoid unnecessary scrap, and increase production costs.
