Detailed ways

Below in conjunction with accompanying drawing and embodiment, the utility model is further described:

Embodiment: Referring to Figures 1-3: a centering mechanism suitable for the detection of display screens of different sizes, including a table top 1 and a detection head 2 arranged above the table top 1; the detection head 2 can be the detection of a visual detection device Camera;

Referring to FIG. 1 , two first sliding blocks 3 and two second sliding blocks 4 are protruded on the table top 1 , and the two first sliding blocks 3 are respectively arranged on both sides of the table top 1 in the lateral direction, and the two second sliding blocks 3 The sliders 4 are respectively arranged on both sides of the table top 1 in the longitudinal direction; the two first sliders 3 are slidably arranged relative to the table top 1 in the longitudinal direction, and the two second sliders 4 are slidably arranged relative to the table top 1 in the transverse direction; 1, install the guide rail on the guide rail, and open a straight groove along the movement track of the slider on the guide rail, and install the first slider 3 and the second slider 4 on the guide rail; and the matching chute of the second sliding block 4, the first sliding block 3 and the second sliding block 4 are embedded in the sliding groove;

The sliding track of the first slider 3 intersects vertically with the sliding track of the second slider 4, and the intersection point coincides with the detection reference point on the table 1 corresponding to the detection head 2; in the working state, the two first sliders 3 and the two second sliders 4 can move toward or away from each other along their sliding tracks;

The sliding tracks corresponding to the first slider 3 and the second slider 4 on the table top 1 are respectively provided with scales, and the scales have corresponding scale values, which are used to indicate the positions of the first slider 7 and the second slider 8;

Referring to FIG. 3, 10 is a PG signal generator, and 9 is a display screen; in specific use, first place the display screen 9 on the surface of the table 1, and move the two first sliders 3 and two second sliders. Move the block 4 against the edge of the display screen 9, check the scale on the table 1, slide the first slider 3 and the second slider 4, so that the two first sliders 3 in the front and rear directions are on the table 1 The corresponding scales are equal, and the two second sliders 4 in the left and right directions also have the same scales on the table 1. Ensure that the scales are equal so that the midpoints of the display screen 9 in the length and width directions are the same (that is, the center of the display screen 9). point) is located at the detection reference point of the detection head 2 on the table 1, so that the centering of the display screen 9 can be realized; then the display screen 13 is illuminated by the PG signal generator 10 (the two are connected by a data line), Carry out further testing.

Referring to FIG. 2 , a two-way screw 5 is threaded between the two first sliders 3 and between the two second sliders 4 , and an escape groove for accommodating the two-way screw 5 is opened on the table 1 6. The two first sliders 3 and the two second sliders 4 are arranged symmetrically and equidistantly with respect to the axial midpoint of the two-way screw 5.
