Description
Technical Field
The invention relates to the technical field of pin welding devices, in particular to intelligent automatic electronic component pin welding equipment.
Background
A ceramic gas discharge tube (GDT for short), wherein the inside of the ceramic gas discharge tube is provided with a closed device formed by filling inert gas in one or more discharge gaps; the electrical properties of ceramic gas discharge tubes depend on factors such as the gas species, gas pressure, internal electrode structure, fabrication process, etc. When the voltage applied to the two electrode terminals (electrode pins) reaches the voltage which breaks down the gas in the GDT, discharge is started, the high impedance is changed into low impedance, surge voltage is rapidly shorted to be close to zero voltage, and overcurrent is released to the ground, so that the subsequent circuit is protected.
For the ceramic gas discharge tube, two ends of the ceramic gas discharge tube are respectively provided with an electrode, each electrode is welded with an electrode pin, and the electrode pins are generally formed by welding copper wires at the electrode positions.
In the production and preparation process of the ceramic gas discharge tube, electrode pin welding processing is generally realized by a pin welding machine, namely, copper wires are welded at electrode positions of the ceramic gas discharge tube by the pin welding machine to form electrode pins. For a pin welder, electrode pin welding processing is realized mainly through a pin welding assembly.
It should be noted that, for the existing pin welding machine applied to the ceramic gas discharge tube, in the process of using the pin welding assembly to realize electrode pin welding processing, the pin welding assembly needs to realize clamping and fixing of the ceramic gas discharge tube by means of a corresponding clamping and positioning structure, and then the welding electrode is moved to realize contact between the welding electrode and the electrode on the corresponding side of the ceramic gas discharge tube. Because the welding motor and the clamping and positioning structure of the existing pin welding assembly are mutually independent structures, namely the whole pin welding assembly has the defects of complex structure and low welding efficiency.
In addition, for the existing pin welding machine applied to the ceramic gas discharge tube, the wire feeding is generally realized by adopting a manual wire feeding mode, namely, copper wires cut into specified lengths are positioned and placed at the position of a pin welding assembly manually; the wire feeding mode has the defects of low automation degree, high labor cost and low working efficiency.
