Description

Technical Field

[0001] The present application belongs to the technical field of display screen detection, and specifically relates to a display screen detection device. Background Art

[0002] As the size of display screens continues to increase, the difficulty of display screens in the manufacturing process gradually increases, and the defective ratio also increases accordingly. In order to reduce the flow of defective products to the client, display screen manufacturers generally conduct 100% full inspection. In order to improve the production pass rate and ensure the quality of finished product shipments, the client generally conducts corresponding selection before the display screen is assembled online. It can be seen that the inspection of display screens has become an indispensable thing in the production process. In the prior art, traditional cable sockets are generally used to connect display screens. When testing, the flexible circuit board (FPC) of the display screen must be inserted into the cable socket first. The alignment is difficult, and it is difficult to quickly insert the FPC of the display screen into the cable socket. In addition, the inspection personnel need to operate with both hands at the same time. The operation steps during the test are numerous and cumbersome, the operation is difficult, and the test efficiency is low. In addition, the cable socket needs to be repeatedly fastened and unfastened, which is very easy to damage and needs to be replaced frequently, resulting in large material loss.

[0003] At present, when inspecting existing display screens, the same inspection device can only inspect display screens of fixed sizes, which has great limitations and leads to low efficiency in inspecting display screens. Summary of the invention

[0008] By adopting the above technical solution, when the display screen to be tested needs to be placed inside the positioning clamping groove, the pull rod can be pulled to cause the movable clamping block to move upward on the inner side of the positioning clamping groove. When the display screen to be tested is placed, the pull rod is released and the movable clamping block cooperates with the positioning clamping groove to clamp it under the action of the compression spring.

[0009] Furthermore, a driving mechanism is provided on the surface of the bottom plate at one side of the fixing box, and a driving switch is provided on the surface of the driving mechanism.

[0010] By adopting the above technical solution, the display screen to be detected can be made to reach the detection position through the provided driving mechanism cooperating with the driving switch.

[0011] Furthermore, a device body is arranged at the edge of the upper surface of the bottom plate, and a power switch is arranged at the edge of the top surface of the device body.

[0013] Furthermore, a positioning groove is provided on the middle surface of the device body, a cable positioning structure is provided on the surface of the positioning groove, and a conductive contact piece is provided in the middle of the cable positioning structure.

[0014] By adopting the above technical solution, the positioning groove is provided to facilitate the installation of the wiring positioning structure, thereby facilitating the placement of the conductive contact piece for subsequent detection work.

[0015] Furthermore, a contact device is arranged above the positioning groove, and four guide pillars are arranged on the surface of the contact device, a pressing block is arranged on the middle surface of the contact device, and a plurality of conductive members are arranged on the lower surface of the pressing block.

[0016] By adopting the above technical solution, the contact device arranged above the positioning groove cooperates with the guide pillar, the pressure block and the conductive member to detect the object inside the positioning groove.

[0017] Furthermore, a placement plate is provided on the inclined surface of the fixing box, and soft pads are bonded to the surfaces of the placement plate, the positioning clamping groove and the movable clamping block.

[0018] By adopting the above technical solution, the placement plate arranged on the inclined surface of the fixing box facilitates the placement of the display screen to be tested, and the soft pads bonded on the surfaces of the placement plate, the positioning clamping groove and the movable clamping block can play a certain protective role.

[0019] In summary, due to the adoption of the above-mentioned technical scheme, the beneficial effect of the present application is: in the present application, when display screens of different sizes are to be inspected, starting the bidirectional motor arranged inside the fixed box can drive the threaded screw to rotate, and the cooperating bearing can cause the movable block to move on the surface of the threaded screw, and at the same time, the cooperating sliding groove can cause the movable block to drive the positioning clamping groove to move on its surface, so that the structure can be adjusted and clamped according to the size of the display screen to be inspected, thereby improving the efficiency of display screen inspection.
