Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, a screen alignment lighting detection device includes a carrier 2 for placing a screen 3, the carrier 2 is driven by a first module 1, the first module 1 includes a servo motor and a screw rod linear motion system, and the servo motor is connected with the screw rod linear motion system.

The upper side of the carrier 2 is provided with a first camera 7 used for detecting the screen 3, a lens 6 is arranged below the first camera 7, the first camera 7 and the lens 6 are respectively driven by a second module 13 and a third module 12, the second module 13 and the third module 12 respectively comprise a servo motor and a screw rod linear motion system, and the servo motor is connected with the screw rod linear motion system. The second module 13 and the third module 12 respectively control the first camera and the lens, and automatic switching of detection of products with different sizes can be achieved.

A second camera 11 for alignment is arranged on one side of the carrier 2, and an optical prism 10 is arranged on one side of the second camera 11.

A test pressure head 4 is further arranged above the carrier 2, the test pressure head 4 is respectively connected with an air cylinder 5 and an XY rotary platform 9, and the XY rotary platform 9 is connected with a servo motor; the second camera 11, the air cylinder 4 and the servo motor are respectively connected with the controller.
