Description

Technical Field

[0001] This utility model belongs to the technical field of screen processing equipment, and in particular relates to a testing machine for screen processing. Background Technology

[0002] A screen is an electronic display device used to display information, images, videos, or other visual content. It is usually composed of a series of pixels and presents images through different optical or electronic means. Screens are widely used in various electronic devices such as televisions, computers, mobile phones, tablets, and billboards. Its working principle is to excite the display unit by using a backlight or self-emissive material (such as OLED) to control the brightness and color of each pixel to generate a visible image.

[0003] In the prior art, Chinese Patent Publication No. CN207423492U discloses an inspection machine for screen processing, including a machine body, an inspection platform for placing the screen, and an inspection mechanism for inspecting the screen. The inspection mechanism can move towards or away from the inspection platform. The inspection machine for screen processing of this utility model has an inspection mechanism that can move relative to the inspection platform, making inspection more convenient and achieving better results.

[0004] However, the above-mentioned device still has the following problems in its implementation: During the detection process, the system performs single light transmission detection from above the screen through the main camera and auxiliary camera, which cannot simultaneously and comprehensively detect multiple complex defects such as scratch depth and color difference of the screen. This limits the accuracy and comprehensiveness of the detection effect and may cause some defects to be missed in time. Secondly, during the detection process, once a problem is found in the screen, the system cannot automatically separate or remove the defective screen. Manual intervention is still required to remove the defective screen for subsequent processing. This operation not only increases the workload of manual intervention, but also greatly affects the detection efficiency.

[0005] To address these issues, we provide an inspection machine for screen processing. Utility Model Content

[0006] The purpose of this invention is to provide an inspection machine for screen processing. By combining the inspection component and the ejection component, it solves the problems of existing inspection machines for screen processing, such as limited inspection methods and the inability to automatically separate defective screens.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0016] 1. This utility model utilizes a combination of infrared sensors, laser scanners, and CCD camera lenses in its detection components to simultaneously detect multiple indicators of the screen, such as light transmission uniformity, scratch depth, and color deviation. This significantly improves the comprehensiveness and accuracy of the detection, effectively solving the problem of missed detections in traditional single-detection methods. Furthermore, the component employs a non-contact air-jet sorting design driven by an air pump, which can quickly and accurately push defective screens to the collection area. This not only avoids secondary damage that may be caused by mechanical clamping but also greatly improves sorting efficiency, achieving full automation of the detection and sorting process.

[0017] 2. This utility model uses a multi-sensor collaborative detection scheme, which significantly improves the detection accuracy compared to traditional single detection methods. After adopting a pneumatic non-contact sorting mechanism, the sorting speed is increased, which is more efficient than manual sorting. At the same time, it reduces the screen damage rate during the sorting process. This integrated design is particularly suitable for screen production lines that require high-precision detection and efficient sorting. It significantly reduces labor costs and production losses while ensuring product quality.
