[0026] Example: Figure 1 is a schematic diagram of a structure of a detection device for a display panel provided by an embodiment of the present invention, such as Figure 1 As shown, the detection device includes a base 1, a crimping assembly 2, a lifting module 3 and a detection camera 4.

[0027] The crimping assembly 2 includes a carrier 21, a crimping module 22, a driving member 23 and a crimping camera 24. The carrier 21 can be movably arranged on the base 1. The crimping module 22 is used to crimp and light up the display panel. The driving member 23 is used to drive the crimping module 22 to move along a third direction. The driving member 23 is located on the carrier 21.

[0028] The lifting module 3 is located on the base 1 , and is used to drive the inspection camera 4 and the crimping camera 24 to move along the third direction (Z-axis direction). The crimping camera 24 and the inspection camera 4 are both used to take pictures of the display panel on the stage 21 .

[0029] For a detection device for a display panel provided by an embodiment of the present invention, when testing the display panel, first, the display panel is placed on the carrier 21, and the crimping camera 24 and the detection camera 4 are located above the display panel. And according to the thickness of the display panel, the crimping camera 24 is lifted and lowered by the lifting module 3, so that the crimping camera 24 can achieve height adjustment through the lifting module 3, and achieve precise focusing, which is convenient for subsequent photography. Then, the display panel is photographed by the crimping camera 24, and the display panel is moved to adjust the test point on the display panel until the test point is aligned with the crimping module 22 in the third direction, so that the display panel can be photographed and phased by the crimping camera 24, and then the position of the test point on the display panel relative to the crimping module 22 can be accurately adjusted, and finally the test point is located directly below the crimping module 22. Then, the crimping module 22 is driven to descend by the driving member 23, so that the crimping module 22 crimps and lights up the display panel. Then, the detection camera 4 is lifted and lowered by the lifting module 3 to achieve precise focusing, which is convenient for photography and optical detection. The display panel is photographed by the detection camera 4, and the spatial position of the stage 21 on the base 1 is adjusted until the lens of the detection camera 4 is perpendicular to the display panel. This not only enables the detection camera 4 to achieve height adjustment through the lifting module 3, but also allows the spatial position of the stage 21 and the display panel to be adjusted after taking the photo, and thus can compensate for the installation error of the detection camera 4 relative to the stage 21 to ensure the subsequent optical inspection. Finally, the display panel is optically inspected by the detection camera 4. This inspection equipment integrates the crimping station and the inspection station on the base 1, which can achieve precise crimping and optical inspection at the same time, and the display panel is always located on the stage 21, without the need to be transferred to different stations, which greatly reduces the space occupied.

[0030] That is to say, the detection device for display panels provided by the embodiment of the present invention can not only realize the height adjustment of the crimping camera 24 and the detection camera 4 through the same lifting module 3 when detecting display panels of different thicknesses, thereby reducing the testing cost, but also realize precise crimping and optical detection at the same time, thereby greatly reducing the space occupied.

[0031] It is easy to understand that the detection camera 4 provided in the embodiment of the present invention can not only obtain the spatial position of the display panel by taking pictures to compensate for the installation error of the detection camera 4, but also perform optical detection on the display panel.

[0032] Exemplarily, the lifting module 3 may be a linear module or a telescopic motor. The display panel may be a Micro LED or a Micro OLED. In addition, a bracket is provided on the output end of the lifting module 3, and the detection camera 4 and the crimping camera 24 are arranged on the bracket at intervals.

[0038] In this embodiment, the detection device further includes a detection adjustment module 5, which is used to drive the stage 21 to move in the first direction, move in the second direction, rotate in the first direction, rotate in the second direction, and rotate in the third direction. The detection adjustment module 5 can adjust the spatial position of the stage 21 and the display panel relative to the detection camera 4, and with the cooperation of the lifting module 3, the adjustment of six degrees of freedom is finally achieved, thereby finally ensuring that the detection camera 4 is facing the display panel and the spacing meets the set requirements.

[0039] Furthermore, the detection and adjustment module 5 includes a first detection displacement module 51, a second detection displacement module 52, a first detection rotation module 53, a second detection rotation module 54 and a third detection rotation module 55, all of which are electrically connected to the detection camera 4.

The third detection rotation module 55 can drive the carrier 21 and the display panel to rotate with the Z-axis as the rotation axis. In addition, after the detection camera 4 completes taking pictures of the display module, it obtains the spatial position difference data (including X-axis, Y-axis, θ, RX and RY) between the display panel and the lens of the detection camera 4 through processing and analysis, and transmits the position difference data to the first detection displacement module 51, the second detection displacement module 52, the first detection rotation module 53, the second detection rotation module 54 and the third detection rotation module 55.
