Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a robot detection device for detecting height differences of display screens. Background Art

[0002] With the development of technology and the expansion and diversification of user usage scenarios, the structural and functional requirements for computer monitors, stands, and bases have also become diversified. In particular, some monitors are required to be able to rotate, lift, and quickly disassemble. Therefore, the quality requirements for the stability and consistency of monitor screen assembly production will be higher.

[0003] When monitor screens are produced, it is extremely necessary to conduct height difference detection. Height difference detection is an important part of the computer screen production process. It helps to ensure that the manufacturing of each screen meets the established quality standards and design specifications. Through detection, deviations in the production process can be discovered and corrected in a timely manner, thereby maintaining the stability and consistency of product quality. Height difference may be caused by a variety of factors, such as uneven materials, processing errors, assembly errors, etc. If these defective products are not detected, they may flow into the market, affecting user experience and brand reputation. Through height difference detection, these defective products can be discovered and eliminated in a timely manner, improving the overall quality of the product.

[0004] In the existing process of detecting the height difference of the display screen, an XYZ motion module is usually used to drive a detection sensor, which is first pressed down to one side of the top of the display screen to record the first set of displacement data, and then moved to the other side and pressed down the other side of the top of the display screen to record the second set of height displacement data. The height difference value of the display screen is obtained by the difference between the first set of height displacement data and the second set of height displacement data, so as to judge whether the parallelism of the screen meets the quality standards and design specifications. The main problem of using this existing method of detecting the height difference of the display screen is low efficiency. Each detection requires two data measurements in sequence, and the rhythm is slow, which cannot keep up with the production speed of the assembly line.

[0005] In view of this, how to solve the problems of low efficiency and slow beat in the existing display screen height difference detection method has become a topic to be studied and solved by the present utility model. Utility Model Content
