Description
Technical Field
[0001] The utility model relates to the technical field of displays, in particular to a positioning device for a liquid crystal display. Background Art
[0002] During the production of LCD monitors, multiple processing steps are required, one of which is to install a plastic frame for the monitor. In the process of installing the plastic frame, a plastic frame positioning device is required. The use of the plastic frame positioning device can improve the efficiency and quality of monitor production. Through precise positioning and fixing, the assembly process of the monitor can be ensured to be accurate and avoid misalignment or loosening of the plastic frame. At the same time, the plastic frame positioning device can also improve the automation level of the production line, reduce the need for manual operation, and improve production efficiency.
[0003] However, when some existing positioning devices are used, they may encounter display screens of different sizes, so the size of the positioning devices can also be adjusted. However, most of the existing adjustment methods are adjusted through multiple steps, which results in the need for calibration after adjustment to achieve the purpose of accuracy. Because the adjustment method is cumbersome, each adjustment will consume a lot of time. Therefore, this problem needs to be solved. Utility Model Content
