Description

Technical Field

[0001] This utility model relates to the field of projector technology, specifically to a projector lens testing fixture. Background Technology

[0002] In recent years, as projector technology has continued to innovate, users have increasingly higher demands for image quality. In addition to providing a more stunning viewing experience, they also require continued provision of 1080P and 4K resolution to enhance the visual enjoyment. Under this trend, the imaging lens plays an increasingly important role in the next generation of smart projectors, as it determines the projector's image quality.

[0003] Projector imaging requires high-quality lenses. Lens testing requires projection onto the optical engine, and the lens is attached to the optical engine with screws. The projector body is usually made of metal or plastic. During the early stages of projector development, the lens needs to be disassembled and reassembled multiple times to confirm the resolution. Repeated reassembly and disassembly can cause the optical engine to strip, resulting in the lens not being securely attached and affecting the lens resolution. Utility Model Content

[0027] Working Principle: This utility model discloses a projector lens testing fixture. During use, the hydraulic rod 23 is first shortened, causing the support plate 3, fixed frame 7, first movable plate 9, and second movable plate 10 to move together, moving them away from the optical engine module 2. Then, the imaging lens 8 is placed between the first movable plate 9 and the second movable plate 10. Afterward, the rocker wheel 20 is rotated to reduce the distance between the first movable plate 9 and the second movable plate 10. The rocker wheel 20 drives two bidirectional... The threaded rod 15 rotates, and the bidirectional threaded rod 15 rotates in the inner cavity of the threaded hole 14 and the bearing 17. The first movable plate 9 and the second movable plate 10 move towards each other under the action of the thread, thereby reducing the distance between the first movable plate 9 and the second movable plate 10. The first movable plate 9 and the second movable plate 10 move to clamp and fix the imaging lens 8. Then, the hydraulic rod 23 is controlled to extend. The hydraulic rod 23 drives the support plate 3, the fixing frame 7, the imaging lens 8, the first movable plate 9 and the second movable plate 10 to move together until the imaging lens 8 is pressed tightly on the optical engine 2, and the image of the imaging lens 8 is detected.

At the same time, the distance between the first movable plate 9 and the second movable plate 10 can be adjusted, making the device applicable to the detection of imaging lenses 8 of different sizes, greatly improving its applicability.
