Axial-diode printing die and roll printing method thereof

Abstract

The invention relates to an axial-diode printing die. The axial-diode printing die comprises a printing die body which is rectangular. Printing mark convex bodies in three rows are sequentially distributed on the upper end face of the printing die body in the short-axis direction and comprise the diode polarity color circle printing strip, the product model character die and the product cycle number character die in sequence. The diode polarity color circle printing strip extends in the long-axis direction of the printing die body, and the length of the diode polarity color circle printing strip is 1.2 times that of the perimeter of an axial diode body. The axial-diode printing die has the advantages that the bonding strength of a character die wheel of an original printing die is maintained, namely the size of the bottom size of the original printing die is not changed; secondary roll printing of a diode polarity mark line is omitted, and thus the thickness of ink of the diode body polarity mark line is reduced.

Description

technical field [0001] The invention relates to an axial diode printing mold, in particular to a diode printing mold capable of ensuring that the polarity color ring of the diode is consistent with the printing adhesion of the product model and cycle number. Background technique [0002] Diode, (English: Diode), among electronic components, a device with two electrodes that only allows current to flow in a single direction. Many uses apply its rectifying function. [0003] like figure 1 As shown, the axial diode includes a tube body and pins 1 at both ends of the tube body, and the diode polarity color ring 2, product model 3 and product cycle number 4 are printed on the tube body. This printing requires a special printing mold, and the determinants of printing adhesion include ink thickness, UV lamp intensity, and wax content in the diode body (epoxy resin). [0004] At present, when dealing with axial diode printing, the structure of the printing mold is as follows fig...

AI Technical Summary

Problems solved by technology

The disadvantage of this printing mold is that during the printing process, the ink of the polarity marking line is rolled twice, that is, the thickness of the ink of the polarity marking line is twice the thickness of the ink of the product model and cycle number. When the marking line passes through the UV lamp, the printing adhesion is poor due to the failure of the light to penetrate through it.
