[0002] In the manufacturing process of prisms, the edges of the prisms need to be inked. In the prism edge inking technology, in addition to the inefficient manual inking method, the following two methods are mainly used: first, a single prism is vacuum-absorbed by a fixture, and then the prism angle is rotated to allow the inking needle to apply ink to the corresponding edge. By adjusting the rotation angle, different edges of the prism can be coated with ink; second, a single prism is placed on a prism clamping mechanism, and a scraper mechanism is arranged above the prism clamping mechanism. The scraper mechanism includes a screen, also called a silk screen, and a scraper assembly is arranged on the screen. The scraper assembly is electrically connected to a servo motor and moves horizontally under the control of the servo motor. A pattern forming area corresponding to the position of the prism clamping mechanism is arranged on the screen. The scraper assembly scrapes the ink and prints it onto the prism surface through the screen. The above two methods have the following technical problems: both are inking solutions for a single prism, with low inking efficiency and high requirements for the positioning of a single prism.
