Description

Technical Field

Background

With the rapid development of flat panel displays and the improvement of the living standard of people, display panels have been widely used in daily life and industrial production, and the application fields and application forms thereof are more and more varied. In the production process of display panels, many processes need to perform dot screen inspection on the panel to ensure the manufacturing quality of the display panel. When the display panel is detected, first, the display panel needs to be subjected to screen-lighting crimping, and an electric signal is provided for the display panel by a signal generator so as to light the display panel.

The specification of China patent (application number 2023200804106, publication day 2023, 04 month and 25 days) discloses a front and back pressure contact point screen device and a display panel detection device, which comprises a jig and at least one pressure contact conduction unit, wherein the pressure contact conduction unit comprises a position adjusting component and a pressure head component connected to the movable end of the position adjusting component, the pressure head component comprises an upper pressure head and a lower pressure head which are arranged at intervals in parallel, a first conduction piece for pressure contact point on a plane of a product to be tested is arranged on the lower surface of the upper pressure head, and a second conduction piece for pressure contact point on a plane of the other side of the product to be tested is arranged on the upper surface of the lower pressure head. The automatic crimping mechanism can be suitable for the display panel with crimping points arranged on the upper plane and the lower plane. However, this structural design has the following drawbacks: when the lower pressure head is utilized to align and press the upper PAD point of the panel to be tested, a vacuum adsorption function is added on a jig carrier to suck and fix the panel to be tested, then a probe on the lower pressure head moves upwards to be in contact with the PAD point of the panel to be tested so as to lighten a product, and under some special scenes, when the required spot screen current is larger, the diameter of the probe needs to be increased, so that the thrust of the probe is increased, and when the suction force of the vacuum adsorption is smaller than the thrust of the probe, the vacuum adsorption is insufficient to suck and fix the panel to be tested, and the requirement of lightening the panel to be tested cannot be met. Therefore, it is desirable to develop a structure for holding the panel to be tested, so that the panel to be tested can be stably lightened no matter whether the pushing force of the probe is larger than the vacuum suction force.
