Single-tube clamp for welding PCB (printed circuit board)

Abstract

The invention discloses a single-tube clamp for welding a PCB (printed circuit board). The single-tube clamp comprises an operation table, the circuit board, a rubber sheet, a strip-shaped plate, a strip-shaped frame, a first electric push rod, a push plate, a single-tube body, a fixed clamping plate, a motor, a second electric push rod, a U-shaped frame, a cylindrical sliding rod, a circular steel block, a baffle plate, a movable strip plate, a third electric push rod, a movable clamping plate, a circular electromagnet and a through hole. The single-tube clamp is reasonable in structure, single pipes are conveniently clamped, a clamping and moving function is added, the single pipes are moved to suitable welding positions on the circuit board and clamped and placed one by one, welding time is saved, the first electric push rod pushes the push plate to move forwards, the single-tube body on the strip-shaped plate is moved onto the movable strip plate positioned between the movable clamping plate and the fixed clamping plate, and a next single-tube body to be welded is conveniently placed and clamped.

Description

technical field [0001] The invention relates to a single-tube clamp, in particular to a single-tube clamp for PCB board welding, and belongs to the technical field of circuit board applications. Background technique [0002] Single tube (Insulated Gate Bipolar Transistor), insulated gate bipolar transistor, is a composite fully-controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (insulated gate field effect transistor). The advantages of high input impedance of MOSFET and low conduction voltage drop of GTR, GTR saturation voltage drop, high current density, but large drive current; MOSFET drive power is small, switching speed is fast, but conduction voltage drop is large , small current-carrying density, IGBT combines the advantages of the above two devices, the driving power is small and the saturation voltage is reduced, it is very suitable for the conversion system with a DC voltage of 600V and above, such as AC motors, freque...

AI Technical Summary

Problems solved by technology

[0003] The traditional single tube clamp only has the function of clamping and fixing, and the clamping structure needs to be improved, and it is not convenient to move the clamped single tube to a suitable welding position on the circuit board, and then weld it on another position on the circuit board For a single tube, the operator needs to re-clamp the single tube to be welded with a clamp, and there are many inconveniences in manual operation, which prolongs the time of welding operation and affects the work progress
