When the lifting driving mechanism 50 drives the upper cover 21 to lift, the vertical connecting portion 632 will move along the second guide rail 61, so as to guide the lifting of the upper cover 21 and make the lifting movement of the upper cover 21 more stable. Of course, in other embodiments, the second guiding mechanism may also be a guiding rod.

After the upper cover plate 21 descends and presses the circuit board on the lower cover plate 22, the lifting driving mechanism 50 drives the supporting member 82 to descend so that the guide plate 70 is separated from the rotating member 81, and then drives the pressing member 103 to move downwards along the vertical direction through the pressing driving member 102, so that the pressing member 103 contacts the pressing part 1013 of the pressing member 101 to press the pressing part 1013 downwards, and further drives the lower cover plate 22 to press downwards, thereby further pressing and flattening the circuit board placed on the lower cover plate 22.

The connection position of the first connection portion 1011 on the upper cover plate 21 can be adjusted through the waist-shaped hole, so that the upper cover plate 21 and each pressing piece 101 can be conveniently connected. Specifically, the first connecting portion 1011 and the pressing portion 1013 are plate structures extending substantially in a horizontal direction, the second connecting portion 1012 is a plate structure extending substantially in a vertical direction, the first connecting portion 1011, the second connecting portion 1012 and the pressing portion 1013 may be integrally formed or separately formed and then assembled, and the pressing portion 1013 is spaced apart from the lower surface of the upper cover plate 21 (i.e., a gap is left between the pressing portion 1013 and the lower surface of the upper cover plate 21), so as to ensure that the pressing member 103 has a certain movement space in the vertical direction.

The working principle of the worktable glass cover plate device shown in figures 1-7 is as follows:

when the circuit board needs to be placed or taken down, the upper cover plate 21 needs to be opened, and the step of opening the upper cover plate 21 is as follows: after the industrial personal computer sends an instruction for opening the upper cover plate 21, the pressing piece 103 is driven to ascend by the pressing driving piece 102 so as to separate the pressing piece 103 from the pressing piece 101, which means that no external force is applied among the upper cover plate 21, the lower cover plate 22 and the circuit board; then the lifting driving mechanism 50 drives the supporting part 82 to ascend, drives the rotating part 81 on the supporting part 82 to jack up, the rotating part 81 contacts the guide plate 70 and drives the upper cover plate 21 to jack up together, at this time, the second slider on the connecting part 63 moves upwards along the second guide rail 61 under the pulling force of the upper cover plate 21, and when the lifting driving mechanism 50 drives the supporting part 82 to ascend to the stroke end, the lifting driving mechanism 50 is not moved; the translation driving mechanism 30 drives the guide rail base 64 to move along the first horizontal direction a, so that the upper cover plate 21 moves relative to the lower cover plate 22 along the first horizontal direction a to be away from the lower cover plate 22, and the upper cover plate 21 is opened.

When the circuit board is placed or taken down, the upper cover plate 21 needs to be closed, and the step of closing the upper cover plate 21 is as follows: when the industrial personal computer sends an instruction for closing the upper cover plate 21, firstly, the translation driving mechanism 30 drives the guide rail base 64 to move along the first horizontal direction a, so that the upper cover plate 21 moves along the first horizontal direction a relative to the lower cover plate 22 to be close to the lower cover plate 22, when the upper cover plate 21 moves right above the lower cover plate 22, the lifting driving mechanism 50 drives the supporting piece 82 to descend, so that the rotating piece 81 on the supporting piece 82 is driven to descend, the rotating piece 81 drives the upper cover plate 21 to descend together through the guide plate 70, and at the moment, the second sliding block on the connecting piece 63 moves downwards along the second guide rail 61 under the pulling force of the upper cover plate 21; finally, the pressing driving member 102 drives the pressing member 103 to descend, so that the pressing member 103 contacts and presses down the pressing part 1013 of the pressing member 101, thereby driving the lower cover plate 22 to press down, which is equivalent to applying an external force between the upper cover plate 21, the lower cover plate 22 and the circuit board, so as to close the upper cover plate 21.

As shown in fig. 8-9, the optical inspection apparatus further includes a housing 2, a frame 3, a machine table 4, a linear driving member, a linear light source 5, and a contact linear array camera (or a CCD camera), wherein the frame 3 is disposed in the housing 2, the machine table 4 is disposed at the top of the housing 2, and a base 10 of the working table cover device 1 is slidably disposed on the machine table 4; the linear driving part is arranged on the machine table 4 and can drive the base 10 to do linear reciprocating motion along the first horizontal direction A; the linear light source 5 is fixed on the machine table 4 and stretches across the upper part of the cover plate component of the workbench cover plate device 1; the contact linear array camera is fixed on the machine table 4 and stretches across the lower part of the cover plate assembly, the optical axis of the contact linear array camera and the light of the linear light source 5 are superposed on a straight line of the cover plate assembly, and the length direction of the straight line is perpendicular to the first horizontal direction A. When the linear driving member drives the base 10 to move along the first horizontal direction a, in the moving process of the base 10, the linear light source 5 provides light, and the contact linear array camera is used for scanning the circuit board between the upper cover plate 21 and the lower cover plate 22 to detect whether the circuit board has a problem.
