according to the invention, the flexible display screen is placed on the flexible substrate limiting slide way 5, the connecting piece driving component 4 arranged at the upper end in a sliding manner drives the connecting component 6 at the lower end to move downwards, and the connecting point at the lower end is connected to the contact of the flexible display screen, if the contact of the display screen is normally powered, the jig on-off lamp 10 at the front end can be sequentially lightened, so that the power supply on-off of the flexible display screen can be tested;
the position of the connecting point at the lower end is aligned by moving an adjusting handle 407 in the connecting sheet driving assembly 4, and then the connecting assembly 6 at the lower end is turned over between the driving rod mounting plates 402 through the driving rod 404, so that the connecting assembly can move downwards and is connected to the flexible display screen;
the flexible display screen is driven to move by moving a slide roller toggle button 507 in the flexible substrate limiting slide way 5, the limiting slide roller 509 on the inner side is driven by a slide roller connecting piece 508, the staggered distance between the limiting slide roller and the driving silica gel roller 503 is shortened, so that the flexible display screen can be clamped to move, the driving motor 504 is started to drive one of the driving silica gel rollers 503 to rotate, so that the flexible display screen can be driven to move, and compared with the existing power supply testing jig for transmission of a flexible material, the flexible display screen is more flexible, and the damage to the display screen can be reduced;
the sliding wheels 5088 in the sliding roller connecting piece 508 slide on the stable limit frame 5085, so that the toggle connecting rod 5084 can drive the sliding roller rotating shaft 5083 at the front end to move smoothly, and the display screen is prevented from being excessively extruded;
the driving ejector 602 in the connecting assembly 6 is pressed by the adjusting handle 407 at the upper end, and the connecting sheet inner cylinder 608 at the lower end is pressed by the outer cylinder spring 612 at the lower end downwards, so that the connecting sheet ejector rod 605 at the lower end moves downwards, when the connecting sheet contact 616 in the connecting sheet 607 at the lower end contacts with a contact on the display screen, the inner cylinder spring 611 at the upper end of the ejector rod partition 609 is compressed again, the contact between the two is more flexible, and the display screen can be better protected and detected.
It should be understood that the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it will be obvious to those skilled in the art that other variations and modifications can be made on the basis of the above description, and all embodiments cannot be exhaustive, and obvious variations and modifications may be made within the scope of the present invention.
