An electric cutting tool for lead wires on circuit board

Abstract

The invention discloses an electric cutting jig of a lead on a circuit board. The electric cutting jig comprises an n-shaped support seat, wherein horizontal first grooved rails are formed on the inner walls of both sides of the support seat, a second grooved rail is formed on the inner wall of the support seat on the lower sides of the first grooved rails, threaded sleeves are fixed to the upperend surfaces of both ends of the first grooved rails, insertion holes which communicate with the threaded sleeves are formed in the first grooved rails, fastening screws are in threaded connection with the interiors of the threaded sleeves, a waste frame is inserted into the support seat, flanges are formed on both side walls of the waste frame, and the flanges are inserted into the second groovedrail; a first guide groove is formed in the back end surface of the support seat, an inverted L-shaped lower cutting blade is inserted into the support seat, the lower cutting blade is composed of vertical parts and a horizontal part, guide rods are inserted into the vertical parts of both ends of the lower cutting blade, both ends of the guide rods are inserted and fixed to both side walls of the support seat, and a plurality of lower cutting teeth are formed on the horizontal part of the lower cutting blade. According to the electric cutting jig, a pair of scissors can be replaced to automatically cut, and the cutting speed can be increased, so that the shearing efficiency is effectively improved, and additionally, the labor intensity of shearing workers is reduced.

Description

Technical field: [0001] The invention relates to the technical field of soldering jigs for electronic components, and more specifically relates to an electric cutting jig for lead wires on a circuit board. Background technique: [0002] At present, in the process of making prototypes, the assembly of electronic components and circuit boards is generally done manually. The operation process is to insert the sockets on the electronic components into the corresponding sockets on the circuit board, and then solder and fix them; After soldering, it is necessary to manually cut the pins or leads protruding from the back of the circuit board. At present, the manual structure uses simple scissors to cut one by one. However, a circuit board has many pins or leads. It is more convenient to use scissors to cut one by one. Trouble, low productivity. Invention content: [0003] The purpose of the present invention is to address the deficiencies of the prior art, and provide an electri...
