Problems solved by technology

The problem with the first solution is that the thickness of the connection pattern is the same as that of the functional pattern, and the part of the connection pattern has a relatively large impact on printing, which will reduce the quality of the printed pattern.
The problem with the second scheme is that the thickness of the mesh and the space for wire diameter selection are relatively large, and the compiled graphics are also relatively single.
The metal plates in the above three patents all adopt a two-layer structure, and the two-layer structure needs to be completed by two different processes; Guarantee, resulting in lower accuracy of the obtained metal plate

Abstract

The invention discloses a metal plate. The metal plate comprises a metal sheet, a silk screen and a screen frame, wherein the metal sheet is fixedly connected to the screen frame through the silk screen, a printing channel is arranged on the metal sheet, the printing channel is defined by a non-pattern area on the metal sheet, and connecting units are arranged at intervals in the extending direction of the printing channel; the printing channel comprises an upper opening, a middle opening and a lower opening which are sequentially connected from top to bottom, the size of the middle opening is matched with the size of a printing design pattern, and the upper opening and the lower opening are in a wide opening shape. In addition, the invention further discloses a processing technology of three metal plates. Compared with the metal plate with two layer structures obtained by forming twice in the prior art, the metal plate is of an integral structure which is integrally formed, such that the technology is simplified greatly and the metal plate is higher in precision.

Description

technical field [0001] The invention belongs to the field of printing screens, in particular to a metal screen. Background technique [0002] Traditional metal screens often adopt two schemes. The first scheme is to process only one metal layer by electroplating. This metal layer contains all the patterns, including functional patterns and connection patterns. The problem with the first solution is that the thickness of the connection pattern is the same as that of the functional pattern, and the part of the connection pattern has a relatively large impact on printing, which will reduce the quality of the printed pattern. [0003] The second solution is a metal film version, and the functional pattern layer is made on the mesh. This similar product is to combine the functional pattern layer with the mesh through electroplating, gluing, welding, deposition and other methods. The problem of the second kind of scheme is that the thickness of the gauze and the limitation of th...
