Problems solved by technology

[0002] In the production process of diodes, diodes are usually cut and bent according to the type and use of the diodes. Manual processing often results in curling, asymmetry, and irregular sizes. In order to improve production quality, automatic punching machines are gradually used for cutting. and bending processing, but the current technical considerations are not perfect, and it has the following disadvantages: the diode is prone to shaking during transportation, which will cause the diode to rotate in the mold, and the connection between the two pins on the diode and the horizontal plane of the shear knife Therefore, during the cutting process, the force on the two pins is uneven, causing the pins to break away from the diode after punching and shearing, causing damage to the diode and affecting the qualification rate of the diode; at the same time, when the diode pin is tilted, the staff does not If it is discovered in time, it will easily lead to excessive length of the pins after cutting, which will lead to the unqualified size of the diode pins and reduce the processing quality of the diodes.

Abstract

The invention discloses an automatic punching machine for diode processing. The automatic punching machine for diode processing structurally comprises a punching air cylinder, a diode mould base, an intelligent control panel, a punching machine support seat, a pin processor and an air cylinder fixing frame, wherein the punching machine support seat is of a rectangular structure and is horizontallyarranged above a processing table; the intelligent control panel is fixed to the front face of the punching machine support seat through bolts; and the air cylinder fixing frame is vertically arranged on the top part of the punching machine support seat. According to the automatic punching machine, through arranging pin adjustment devices, before diode pins are cut, a connecting line of two pinsof a diode is automatically adjusted to be parallel to a horizontal plane of a cutter, so that the occurrence of the phenomenon that the pins are separated from the diode after being cut so as to cause the damage of the diode is avoided; and meanwhile, the inclined pins are straightened, so that the occurrence of the phenomenon that the length of each cut pin does not meet the standards is avoided, and the qualification rate of diode pin processing is improved.
