Technical Field
[0001] The present invention relates to the technical field of projector optical component detection, and particularly to a detection device and a detection method for projector optical components. Background Art
[0002] A projector optical component detection device is a special device used to detect and evaluate the performance of projector optical elements. Through precise optical measurement techniques, it ensures that indicators such as light transmittance, refractive index, and optical alignment of optical components such as lenses, prisms, and filters meet the design requirements. Such devices can effectively detect defects in optical components, such as scratches, stains, bubbles, or other problems affecting image quality, ensuring clear imaging and accurate colors in the projector. The projector lens is a key optical element in the projector, used to accurately project the image emitted by the light source onto the target screen. Its quality directly affects the projection resolution and visual experience, and it is an important core component for achieving high-quality projection.
[0003] In the prior art, the projector optical component detection device cannot fix projector lenses with different diameters and different thicknesses and use its detection elements to detect them. Moreover, when the projector lens is placed in the clamping station by the tester, its surface is easily contaminated with dust, and it is impossible to achieve compatibility detection of multi-specification lenses. In addition, due to the sub-optimal design of the clamping station, when the tester places the lens in the clamping station, the lens surface is easily in contact with dust or other pollutants in the external environment, resulting in possible errors during the detection process and affecting the accuracy of the detection results. These problems not only reduce the versatility of the device but also pose challenges to the detection efficiency and the quality control of the lenses. Summary of the Invention

[0015] A detection method for a projector optical component includes the following steps:
[0016] S1. Fixing the light-shielding cover and the projector lens. In the initial state, since the transverse clamping assembly does not act, the safety driving assembly cannot control the longitudinal clamping assembly to act. The worker inserts the projector lens between the transverse clamping assemblies. At this time, the safety driving assembly can control the longitudinal clamping assembly to act, and the focus of the projector lens is incorporated into the optical path of the emission light source. The light-shielding cover is closed, and the main controller controls the safety interlock assembly to lock the light-shielding cover. At this time, the light-shielding cover cannot be opened.
[0017] S2. Performing the dust removal action on the projector lens and resetting.

The vacuum cleaner connected to the external connection pipe on the side surface of the dust extraction plate simultaneously passes through the dust extraction holes on the dust extraction plate. After waiting for a period of time, the follower dust extraction assembly automatically resets.
[0018] S3. Measuring the parameters of the projector lens. The light source emits light. The light source passes through the avoidance hole into the projector lens, and finally the image is projected onto the projection screen. The detection camera takes pictures of the image on the projection screen for detection.
[0019] Compared with the prior art, the present invention has the following advantages:
[0020] 1. At the top of the workbench, the present invention is provided with a light source emitter, a horizontal clamping assembly, a vertical clamping assembly, and a detection camera. The horizontal clamping assembly and the vertical clamping assembly enable the entire testing device to fix projector lenses with different thicknesses and diameters. Specifically, the horizontal clamping assembly initially clamps the projector lens axially, and the vertical clamping assembly can clamp the projector lens longitudinally. By incorporating the focal point of the projector lens into the light path of the light source emitter, the testing device can flexibly adapt to projector lenses with different thicknesses and diameters, improving the compatibility and application range of the device. At the same time, the horizontal clamping assembly achieves initial axial fixation, and the vertical clamping assembly further focuses, accurately incorporating the focal point of the projector lens into the light path of the light source emitter, ensuring the accuracy and efficiency of detection, and effectively avoiding testing errors caused by unstable clamping or focusing deviation.
[0021] 2. At the top of the workbench, the present invention is provided with a light source emitter, a horizontal clamping assembly, a vertical clamping assembly, and a detection camera. A safety drive assembly is arranged between the horizontal clamping assembly and the vertical clamping assembly. After the horizontal clamping assembly initially clamps the projector lens, the vertical clamping assembly can operate, avoiding interference and collision between the horizontal clamping assembly and the vertical clamping assembly, and preventing damage to the clamping components themselves. This design greatly reduces the risk of damage to the clamping components caused by misoperation or synchronization errors, extending the service life of the device. This design improves the safety and reliability of operation. Moreover, the safety drive assembly is completely composed of a pure mechanical structure without electrical control, avoiding equipment failure caused by circuit faults or control system malfunctions, improving the stability and reliability of the system. Mechanical structures usually have a longer service life and lower maintenance costs, and can maintain continuous and stable operation in a high-frequency operation environment. In addition, the pure mechanical structure does not require additional power supply, saving energy, simplifying the overall design of the device, and reducing production and use costs at the same time.
[0022] 3. The present invention is provided with a light-emitting source, a lateral clamping assembly, and a longitudinal clamping assembly on the top of the workbench. A follow-up double-sided dust removal assembly is arranged on the side of the longitudinal clamping assembly. Even after the longitudinal clamping assembly clamps projectors with different diameters, the follow-up double-sided dust removal assembly can still simultaneously remove dust from both sides of projectors with different thicknesses and diameters. The follow-up double-sided dust removal assembly can automatically adjust its position according to the change of the lens size, without additional manual intervention, with simple and efficient operation, improving the intelligent level of the equipment. In addition, this assembly starts the dust removal operation immediately after the lens is longitudinally clamped, avoiding the influence of dust accumulation during the detection process on the test results, thus ensuring the accuracy of the detection and the cleanliness of the lens. This design also improves work efficiency, reduces the risk of lens scratches or contamination caused by manual dust removal, and ensures the safety of the detection process and the high-quality maintenance of the lens.

[0047] The specific implementation steps and principles of the present invention are as follows:
[0048] In the initial state, since the horizontal clamping assembly does not act. Specifically, the output end of the driving cylinder 36 is in an interleaved state with the longitudinal column 27. At this time, the vertical U-shaped rod 34 is on one side surface of the longitudinal column 27, and the driving cylinder 36 cannot push the two safety driving assemblies to control the longitudinal blocks 28 to approach each other, and the distance between the two horizontal plates 21 is the closest.
[0049] The worker inserts the projector lens between the transverse clamping assemblies through the tilting plate 212. The projector lens overcomes the elastic force of the transverse spring 18. At this time, the two transverse plates 21 move away from each other to an appropriate distance. The rectangular hole 211 pulls the transverse U-rod 35 to one end of the longitudinal column 27 through the follower rod 33. At this time, the driving cylinder 36 extends out and can push the longitudinal block 28 at one end of the longitudinal column 27 closer to each other through the transverse U-rod 35, thereby clamping the projector lens to the light path of the emitting light source 17.
[0050] Close the light shield 1, and control the output end of the locking electric push rod 10 to extend into the locking hole 3 of the locking fold block 2 through the main controller 8. At this time, the light shield 1 cannot be opened, and the main controller 8 controls the cylinder 24 to drive the two dust extraction plates 31 to perform dust extraction on the two sides of the projector lens through the common rod 25. After waiting for a period of time, the two dust extraction plates 31 return to their initial positions, and the light emitted by the emitting light source 17 shines on the projection cloth 12 through the avoidance hole 210. The detection camera 15 takes pictures and detects the image received by the projection cloth 12.
[0051] At this time, the safety drive component can control the action of the longitudinal clamping component, the projector lens focus is merged into the light path of the emitting light source 17, the light shield 1 is closed, and the main controller 8 controls the safety interlock component to lock the light shield 1. At this time, the light shield 1 cannot be opened.
[0052] To remove dust from the projector lens and reset it, the air cylinder 24 is sent in to drive the two dust extraction plates 31 to move to the two sides of the projector lens through the common rod 25. The vacuum cleaner connected to the external tube 311 on the side of the dust extraction plate 31 passes through the dust extraction hole 310 on the dust extraction plate 31 at the same time. After waiting for a period of time, the follow-up dust extraction assembly is automatically reset.
[0053] The projector lens parameters are measured, the emitting light source 17 emits light, the light source penetrates into the projector lens from the avoidance hole 210, and the final image is projected onto the projection cloth 12, and the detection camera 15 takes a photo of the projection cloth 12 for detection.
[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
