Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of screen printing, and in particular relates to a square light and thin object positioning device and an operating method thereof. Background Art
[0002] As we all know, the positioning of a square object in a plane requires the restriction of three degrees of freedom, that is, two constraint points on the side of the square object and one constraint point on the adjacent side can completely determine the position of the square object on the plane; for hard square objects whose sides are not easily bent and deformed by thrust, three-point positioning is easy to achieve; but for soft square objects whose sides are easily bent and deformed by thrust, there are not many three-point positioning methods, because when the square object is pushed toward the positioning point, when the corresponding side fits the positioning point, the thrust is difficult to control, and the square object is bent and deformed, resulting in inaccurate positioning. At the same time, during screen printing, if the printing part on the positioning plane has obvious concave and convex surfaces, it will damage the screen printing plate and shorten the life of the screen.
