Abstract

The invention relates to a marking device of a crystal triode. The marking device comprises a rack and a first driving shaft, and the other end of the first driving shaft is connected with a notch gear and a first cam; a second driving shaft and a third driving shaft are arranged below the first driving shaft, and a conveying belt is connected between the second driving shaft and the third drivingshaft; a fixing base is arranged on the conveying belt, and second cams and abutting rings are arranged on the second and third driving shafts; the second cams are located on the inner sides of the abutting rings and abut against the abutting rings, and the upper ends of the abutting rings are connected with a fixed net; sliding rods are fixedly connected to the lower ends of the abutting rings,the sliding rods are slidably connected to the rack, and a driving gear is further connected to the second driving shaft; the driving gear is meshed with the notch gear, and the rack is further slidably connected with an ejecting rod; the lower end of the ejecting rod abuts against the first cam, the ejecting rod is connected with a cross bar, the other end of the cross bar is fixedly connected with a marking bar, and the maringk bar is connected with a marking head. The device solves the problem that a traditional marking device lacks a positioning process and accordingly the printing qualitypoor.

Description

technical field [0001] The invention relates to the field of transistor processing equipment, in particular to a marking device for crystal transistors. Background technique [0002] Triode, the full name should be semiconductor triode, also known as bipolar transistor, crystal triode, is a semiconductor device that controls current, its function is to amplify weak signals into electrical signals with larger amplitude values, and also used as non-contact switches . Crystal triode is one of the basic components of semiconductors. It has the function of current amplification and is the core component of electronic circuits. The triode is made on a semiconductor substrate with two PN junctions that are very close to each other. The two PN junctions divide the whole semiconductor into three parts. The middle part is the base area, and the two sides are the emitter area and the collector area. The arrangement is PNP And NPN two kinds. [0003] The structure of the crystal trio...
