[0031] Specifically, in this embodiment, during operation, manual or external equipment transports the glass cover plate to be inspected into the loading assembly 10. During actual operation, the glass cover plate is installed on the mobile phone screen assembly and transported through the loading assembly; then the inspection assembly 20 performs an appearance inspection on the glass cover plate. If the inspection is qualified, the moving assembly 50 drives the loading assembly 10 to move so that the discharge end of the loading assembly 10 is aligned with the feed end of the first blanking assembly 30, and then the loading assembly 10 transports the glass cover plate to the first blanking assembly 30 and transports it out through the first blanking assembly 30; if the inspection is unqualified, the moving assembly 50 drives the loading assembly 10 to move so that the discharge end of the loading assembly 10 is aligned with the feed end of the second blanking assembly 40, and then the loading assembly 10 transports the glass cover plate to the second blanking assembly 40 and transports it out through the second blanking assembly 40.

In this embodiment, during operation, a glass cover plate to be inspected is placed on the first conveyor belt 102 manually or by an external conveying device, and the inspection assembly 20 then performs a visual inspection on the glass cover plate. If the inspection passes, the moving assembly 50 moves the discharge end of the first conveyor belt 102 via the first mounting frame 101 to align with the feed end of the first blanking assembly 30, and then the first driving unit drives the first conveyor belt 102 to rotate, thereby conveying the glass cover plate to the first blanking assembly 30. If the inspection fails, the moving assembly 50 moves the discharge end of the first conveyor belt 102 via the first mounting frame 101 to align with the feed end of the second blanking assembly 40, and then the first driving unit drives the first conveyor belt 102 to rotate, thereby conveying the glass cover plate to the second blanking assembly 40. Specifically, the first driving unit includes a first driving wheel and a first driven wheel mounted at both ends of the first conveyor belt 102, and a first motor 103 connected to the first driving wheel for driving the first driving wheel to rotate.

[0034] In a specific embodiment, the inspection assembly 20 includes a CCD camera 201 for visually inspecting the glass cover plate, and a moving unit connected to the CCD camera 201 for driving the CCD camera 201 to move over the glass cover plate. In this embodiment, the glass cover plate in the loading assembly 10 is inspected by the CCD camera, and the position of the CCD camera 201 is adjusted by the moving unit to ensure that the CCD camera 201 is in a suitable position for accurate inspection of the glass cover plate, thereby improving the accuracy of the inspection.

[0035] In a specific embodiment, the mobile unit includes a first mobile assembly and a second mobile assembly; the first mobile assembly is adjacent to the loading assembly 10; the second mobile assembly is mounted on the first mobile assembly and is driven by the first mobile assembly to move along a first horizontal preset direction; the CCD camera 201 is mounted on the second mobile assembly and is driven by the second mobile assembly to move along a second horizontal preset direction.

In this embodiment, during operation, when the glass cover fails the initial inspection by the CCD camera 201, the air blowing head 204 moves above the glass cover under the drive of the first and second moving assemblies. At this time, the lifting assembly drives the air blowing head 204 downward. After descending to a preset position, the air blowing head 204 blows air on the glass cover to remove dust from the camera. After the air blowing is completed, the CCD camera 201 re-inspects the glass cover.
