Description

Technical Field

[0001] This utility model relates to the field of remote image screen detection technology, specifically to a device for improving the detection efficiency of remote image screens. Background Technology

[0002] The existing testing methods are small-batch sampling inspections; namely: 1. Color reproduction testing, 2. Image reproduction testing; Color reproduction testing method: Use a chromatograph to test whether there is color deviation in 5 color samples (blue, red, black, green and white). All 5 colors must be tested. The method of graphic restoration detection is as follows: use a camera to detect whether the three graphic boards (grid line graph, dot line graph, and checkerboard graph) are stretched or deformed at different imaging distances, and all three shapes must be detected, and each imaging distance must be detected three times; both the color board and the graphic board are square thin aluminum plates with plain color paper or graphics pasted on one side. Current inspection methods primarily involve manually replacing color and graphic plates, which is labor-intensive for inspectors, slow-paced, and inefficient, making it unsuitable for full inspection in mass production.

Detailed Implementation

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] Example like Figure 1-3As shown, a device for improving the detection efficiency of a remote image screen includes a device frame 1. Inside the device frame 1, there are an automatic color plate switching mechanism 3 and an automatic shape plate switching mechanism 29. The upper end of the automatic color plate switching mechanism 3 and the automatic shape plate switching mechanism 29 is provided with a first support frame 2. The end face of the first support frame 2 is provided with a first remote image screen 5 and a second remote image screen 6. One end of the first remote image screen 5 and the second remote image screen 6 is provided with a camera 8 and a chromatograph 4, respectively. The other side of the second remote image screen 6 away from the first remote image screen 5 is provided with a display screen 9. The camera 8 is fixed to the end face of the first support frame 2 by a camera bracket 7.

[0018] In this embodiment, the shape plate automatic switching mechanism 29 includes a switching frame 10, a second support frame 11 at the lower end of the switching frame 10, and a first driving mechanism connected thereto at one end of the switching frame 10.

[0019] The first drive mechanism consists of a first rotary servo motor 18, a first rotary reducer 19, and a first coupling 20.

[0020] The second support frame 11 has first bearing seats 21 symmetrically arranged on both ends, which are connected to the switching frame 10 and the first coupling 20.

[0021] The lower end of the second support frame 11 is provided with a lifting plate 14 connected thereto. The other side of the lifting plate 14 away from the second support frame 11 is provided with a lifting mechanism. The lifting mechanism includes a lifting module 15 that is movably connected to the second support frame 11. The upper end of the lifting module 15 is provided with a lifting reducer 16 and a lifting servo motor 17 in sequence. The height of the shape plate is automatically switched by adjusting the lifting mechanism. During the detection, the first rotary servo motor and the first rotary reducer drive the switching frame to rotate so as to detect different shapes.

[0022] The color plate automatic switching mechanism 3 is composed of a hexagonal switching frame 22, and a second drive mechanism connected to it is provided in the middle of one side of the hexagonal switching frame 22.

[0023] The second drive mechanism consists of a second rotary servo motor 28, a second rotary reducer 27, and a second coupling 26.

[0024] The hexagonal switching frame 22 is symmetrically provided with second bearing seats 25 on both sides, and the second bearing seats 25 are fixedly set with the internal support crossbar of the equipment frame 1. The hexagonal switching frame is rotated by the second rotary servo motor and the second rotary reducer to realize the switching of color plates, realize automatic switching of color plates and perform detection.

[0025] The outer sides of the switching frame 10 and the hexagonal switching frame 22 are respectively provided with a shape plate 12 and a color plate 23, and are respectively fixed to them by a first pressing block 13 and a second pressing block 24.

[0026] Both color swatch 23 and shape swatch 12 are 4mm thick aluminum plates, and their surfaces are covered with plain color paper or graphic paper.

[0027] Three graphic boards (dot-line graph, grid graph, and chessboard graph) are fixed to three faces of a tetrahedral rotating frame using clamping blocks, leaving one mounting face of the tetrahedron as a spare. A rotary servo motor drives the tetrahedral rotating frame to rotate in 90° increments, completing one shape board switching for each unit of rotation. A lifting linear module uses a lifting servo motor to lift the shape board and the entire rotating mechanism, achieving detection distance switching. Therefore, this mechanism can automatically switch between shape boards and detection distances. Five color plates (blue, red, black, green, and white) are fixed to the five faces of the six-sided rotating frame by pressure blocks, with one remaining mounting face reserved. The rotating servo motor drives the six-sided rotating frame to rotate in 60° units. Each rotation unit completes one color plate switching, and the color plates do not require lifting or lowering. The color and shape plates are automatically switched by rotation, and the lifting module drives the entire rotating mechanism to switch the detection distance of the shape plate.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
