Printed circuit board positioning device based on ratchet wheel positioning principle

Abstract

The invention relates to the technical field of printed circuits. The invention further discloses a printed circuit board positioning device based on the ratchet wheel positioning principle. The positioning device comprises a supporting frame and the outer portion of the supporting frame is fixedly connected with an overturning motor. A main gear is fixedly connected to the outer part of the overturning motor; the outer portion of the main gear is connected with an overturning toothed bar in an engaged mode. an overturning gear is connected to the outer part of the overturning toothed bar in ameshing manner; a fixing frame is fixedly connected to the outer part of the overturning gear; a moving motor is fixedly connected to the interior of the fixing frame; the overturning motor, a main gear, the overturning toothed bar, the overturning gear and the fixing frame are matched for use; therefore, the effect of conveniently adjusting the angle of the fixing frame is achieved, the printedcircuit substrate can be adjusted to a proper angle, dispensing and welding operation is facilitated, the using effect is effectively improved, overturning operation of the printed circuit board is facilitated, operation is easy, the overturning operation difficulty of the printed circuit board is reduced, time waste is effectively reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of printed circuits, in particular to a printed circuit board positioning device based on the ratchet positioning principle. Background technique [0002] Circuit printing adopts photoplate making technology, that is, etching the bottom plate of the photographed picture on a copper plate or zinc plate, and using this copper plate or zinc plate for printing has made significant progress compared with traditional circuit boards. Today, all computers and All electronic products use printed circuits. When used, the printed circuit is usually etched on the printed circuit substrate, and all electrical components are connected to the printed circuit substrate by soldering and dispensing on the printed circuit board to make a circuit. When welding and dispensing electrical components, it is usually necessary to clamp and fix the printed circuit board. [0003] During the clamping process of the existing printed ci...

AI Technical Summary

Problems solved by technology

[0003] During the clamping process of the existing printed circuit board fixture device, the clamping operation is complicated by screws, and the clamping force is not controlled accurately, which is easy to cause damage to the circuit board and cause unnecessary economic losses. The printed circuit board can only be fixed on a plane, and the glue dispenser and welding machine can only glue and weld on the plane, to complete relatively simple glue and welding, and the circuit board needs to be turned over, and the circuit often needs to be disassembled. Re-clamping leads to complex operation and low work efficiency, and the existing circuit board fixture device needs to customize a specific mold for each circuit board to adapt to the fixing of circuit boards of different sizes, thus greatly increasing the cost of the mold , reducing economic benefits
