Problems solved by technology

At present, when testing different performances of the same process stage of the display panel, it is necessary to use different detection signals and different testing equipment. During the testing process, most of the connectors of the display panel to be tested are directly crimped; completing a process stage, it is often necessary to repeatedly crimp the connector of the display panel to be tested. Such repeated crimping will cause great damage to the connector of the display panel, and even cause the entire display panel to be scrapped in severe cases; After repeated crimping, it is easy to cause poor crimping during the detection process, resulting in inaccurate detection results, or even failure to complete the detection

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as Figure 1-2 As shown, a display panel test carrying device of the present invention includes a carrier 1 and a test base 2, the display panel 3 to be tested is placed in the groove 1111 of the supporting plate 111 of the carrier 1, and the connector 31 of the display panel 3 Connect with the PCB signal transfer board 13, transmit the detection signal of the display panel 3 to the metal dot matrix 1321 of the PCB signal transfer board 13, and the probes 246 on the probe assembly 24 on the test base 2 contact the metal dot matrix 1321 The probe 246 does not need to be directly connected to the connector 31, which not only protects the product, but also ensures the success rate of conduction. The structure is simple, the operation is convenient, and it is compatible with non-testable stations.

Abstract

The invention relates to a bearing device for display panel test. The bearing device includes a carrier and a test base. The bearing device is connected with a connector of a display panel through a PCB signal adapter plate, and transmits a detection signal of the display panel to a metal lattice of the PCB signal adapter plate. The display panel can be detected by making the bearing device and the metal lattice of the PCB signal adapter plate form a circuit directly, which reduces the damage caused by repeated pressing of products. The metal lattice of PCB signal adapter plate is detected directly, which avoids an inaccurate test result caused by conduction failure of the connector of the display panel. Support pillars are arranged at the four corners of the base to locate the hold the carrier and make the carrier connected accurately. A cylinder drives a probe component to move up and down to complete signal on / off operation. The bearing device for display panel test has the advantages of simple operation, high success rate of conduction and high detection efficiency. The structure of the bearing device can be compatible with non-testable workstations.
