[0040] It should be noted that the plate to be inspected in the embodiment is a rectangular glass plate, and is horizontally placed on the table top during inspection.It can be understood that the table top can be a dedicated inspection table, a desktop or a support capable of placing glass, and the specific form is not limited, and the embodiment is described by taking the inspection table as an example.The driving mechanism 1 in the embodiment is installed on the inspection table.

[0041] Referring to Figures 1 to 4Specifically, the driving mechanism 1 comprises a base 11, a driving frame 12 and a driving seat 13. The base 11 is installed on the upper surface of the inspection table. Two bases 11 are arranged in parallel and located on opposite sides of the glass. The upper portion of each base 11 is connected with a first guide rail 111 in a first direction. The first direction is parallel to the length direction of the glass. The driving frame 12 comprises two vertical supporting legs 121 and a cross beam 122 arranged at the top of the supporting legs 121. Two supporting legs 121 and two first guide rails 111 are arranged in one-to-one correspondence. The bottom end of the supporting leg 121 is connected with the first guide rail 111 in a sliding manner. The cross beam 122 is arranged in a second direction. The second direction is perpendicular to the first direction and parallel to the width direction of the glass. The two ends of the cross beam 122 are connected with the top of the two supporting legs 121, respectively. Thus, the driving frame 12 is connected with the first guide rail 111 in a sliding manner.

[0042] Further, the cross beam 122 is provided with a second guide rail 123 on one side and the bottom thereof in the second direction. The driving seat 13 is arranged in an L shape. The driving seat 13 is connected with the two second guide rails 123 in a sliding manner. The inspection mechanism 2 and the marking mechanism 3 are connected with the bottom of the driving seat 13. The side of the cross beam 122 away from the second guide rail 123 is provided with two sprockets 124 arranged in rotation in the second direction. In this embodiment, two sprockets 124 are taken as an example. One of the sprockets 124 is connected with a hand wheel 126. The two sprockets 124 are connected through a chain 125. The chain 125 is connected with a connecting plate 127. The connecting plate 127 is connected with the driving seat 13.

[0043] Based on the above, when the staff pushes the supporting leg 121, the driving frame 12 can slide along the first guide rail 111 in the length direction, i.e., the driving seat 13 moves in the first direction. When the staff rotates the hand wheel 126, the chain 125 rotates through the rotation of the sprocket 124, which drives the driving frame 12 to slide along the second guide rail 123 in the length direction, i.e., the driving seat 13 moves in the second direction. Thus, the driving seat 13 can move above the glass. The moving area covers the upper surface of the glass. Thus, the inspection mechanism 2 and the marking mechanism 3 can reach any position above the glass. The size of the glass does not limit the inspection work. The blind area of the offline glass inspection is eliminated. The convenience of the glass inspection work is improved.

In this embodiment, one side of one of the bases 11 and one side of the cross beam 122 are connected with a scale ruler 112, thereby forming the first scale marks and the second scale marks. Since the first direction is parallel to the length direction of the glass, and the second direction is parallel to the width direction of the glass, the first scale marks and the second scale marks can be used to accurately position the current position of the driving seat 13. When a defect is found on the glass, the position of the defect on the glass can be accurately positioned, which facilitates subsequent re-inspection, follow-up inspection, and slice sampling. In other embodiments, the first scale marks and the second scale marks can also be formed by directly engraving on the base 11 and the cross beam 122.
