Description

Technical Field

[0001] The utility model relates to the technical field of diode processing equipment, in particular to a diode foot cutting machine. Background Art

[0002] A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). A diode has two electrodes, the positive electrode, also called the anode; and the negative electrode, also called the cathode. When a forward voltage is applied between the two electrodes of the diode, the diode is turned on, and when a reverse voltage is applied, the diode is cut off. The conduction and cutoff of the diode are equivalent to the connection and disconnection of a switch.

[0003] In the manufacturing process of existing diodes, the length of the actual pins of the diodes is generally longer than the length required for actual use. Therefore, in actual use, the pins of the diodes generally need to be partially cut off to obtain the actual required length. In the process of partial cutting, the existing diodes generally need to be fixed first, and then the pins are partially cut off. In the process of fixing the diodes, if the diodes are rigidly fixed, the diodes may be damaged. Therefore, a pin cutting machine that can elastically fix the diodes is needed. Utility Model Content

Both sides are connected with vertical slide bars 25, the cutting knife seat 23 is vertically slidably connected to the two vertical slide bars 25, the pump body 21 is installed above the mounting frame 13, and the lower end of the vertical telescopic push rod 22 passes through the mounting frame 13 and is connected to the cutting knife seat 23; in the process of cutting the pins of the diode 11, the utility model controls the vertical telescopic push rod 22 to extend by opening the pump body 21, thereby pushing the cutting knife seat 23 and the blade 24 downward, so as to cut the pins of the diode 11 located below the blade 24.

The pump body 21 controls the vertical telescopic push rod 22 to extend, thereby pushing the cutting knife seat 23 and the blade 24 downward, thereby cutting the pin of the diode 11 located below the blade 24; the diode 11 of the utility model adopts elastic clamping, which is not easy to damage the diode 11.
