The previous detection method is to put the product on the marble platform and use the three-coordinate detector to test the flatness of the product. Due to the large area of the back plate, it takes a long time to scan point by point. For example, a 30-inch back plate The plate detection time is about 1.0~1.2 hours.

detailed description

The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

Referring to Fig. 1 to Fig. 4, the backboard detection ruler A of the present invention includes more than one ruler unit 1; it should be noted that different ruler units 1 can be integrally processed and formed as a whole.

With reference to shown in Figure 1, the ruler unit 1 is divided into: a leaning plate 11 of a plate structure held by the human hand, a detection edge surface 12 formed on the edge of the leaning plate 11 plate surface 111, the leaning plate 11 has two parallel and shaped The same plate surface 111, the detection edge surface 12 is perpendicular to the plate surface 111 of the backing plate 11; different ruler units 1 form a fixed connection; the plate surface 111 of the backing plate 11 is provided with a nameplate area 13 for marking identification symbols ; More than one right-angle stepped structure 121 is formed on the detection edge surface 12 . The above is the basic composition of a ruler unit 1 .

The detection edge surface 12 is generally composed of a plurality of planes, and its main function is to fit the parts to be detected, so as to detect whether these parts are qualified.

As a preferred solution, the profile of the board surface 111 of the backing plate 11 has two parallel straight short sides 112 and a straight long side 113 perpendicular to the straight short side 112, and the straight long side 113 connects the endpoints of the two straight short sides 112 , the other endpoints of the two straight short sides 112 are connected by the edge of the detection edge surface 12 .

The edge of the detection edge surface 12 is called a detection edge 122 , and the detection edge 122 includes a straight line segment parallel to the straight short side 112 or the straight long side 113 . The detection edge 122 refers to the contour line at the intersection of the outermost edge of the detection edge surface 12 and the board surface 111 , or the contour line of the board surface 12 here. The specific design of this contour line should be determined according to the detection situation.

It should be noted that the detection edge surfaces 12 of all the scale units 1 are formed on the same side of the plate surface 111 of the back plate 11 , and the thickness of the back plates 11 of the scale units 1 is the same.

According to the structure and flatness of the display backplane, formulate the detection edge surface 12 of the ruler unit 1 corresponding to the standard display backplane; the detection edge surface 12 is a ladder structure, and the number of steps can be detected on the display backplane according to needs. It is determined by how many positions with different flatness, and the right-angled stepped structure 121 is clipped on the edges of these positions. Combine different ruler units 1 according to the structure and flatness of the backplane of the display, and hold the backplane 11 by human hands to make the backplane detection ruler A at the end of the detection edge surface 12 correspond to the backplane of the display. If there is no gap Correspondence means that the display backplane is qualified, and if it cannot correspond seamlessly, the display backplane is unqualified.

As another embodiment, the board surfaces 111 of the leaner boards 11 of different scale units 1 are in a vertical or parallel relationship; as an embodiment, the backboard detection scale A can be made of metal materials. More specifically, when the number of ruler units 1 is 2, the board surfaces 111 of the back plates 11 of the two ruler units 1 are perpendicular to each other. In this way, it can be detected horizontally and vertically together, which greatly saves the detection time.

The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the above-mentioned embodiments do not limit the present invention in any form, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
