Pen-type solder stick electric extruding feeder

Abstract

The invention discloses a pen-type solder stick electric extruding feeder. The pen-type solder stick electric extruding feeder is characterized in that a solder stick reel is mounted on a rotating shaft, a right upper straightening wheel and a left upper straightening wheel are mounted on a straightening device housing through bearings, a lower straightening wheel is mounted on the straightening device housing through a bearing, the bottom surface of an upper wire feeding roller is propped against the top surface of a solder stick, the top surface of a lower wire feeding roller is propped against the bottom surface of the solder stick, a connecting sleeve is connected to and mounted on a penholder through threads, a cam is mounted on the output shaft of a driving motor and propped against a pushing plate, the pushing plate is fixedly mounted on a press bar, the press bar is mounted in the central hole of the connecting sleeve, a spring sleeves an inner tube, the right end of the spring is propped against an annular lug boss on the left side of the interior of the penholder, the left end of the spring is propped against the right end surface of the press bar, the inner tube is mounted in the penholder, a pen point is connected to and mounted on the penholder through threads, and clamping petals are mounted at the right end of the inner tube. The pen-type solder stick electric extruding feeder is simple to manufacture and convenient to use, and the use convenience and the health security of welding personnel are improved.

Description

technical field [0001] The invention belongs to the technical field of welding tools for electronic products, and in particular relates to a pen-type solder wire electric extrusion feeder. Background technique [0002] On the one hand, during the continuous development of electronic technology, researchers often solder some electronic components when developing products. During the soldering process, solder needs to come into contact with human skin. However, some solder wires contain heavy metals such as lead. Heavy metals are toxic to the human body. On the other hand, the hand-held method used by welders when soldering electronic products requires the welders to constantly stretch the solder wire on the solder wire reel, which leads to a decline in welding efficiency. [0003] Patent No.: CN200820049916 published a hand-held gun-shaped automatic tin feeder, which is characterized by one-handed operation, which is convenient for factories and other places that require lar...
