Embodiment Construction

[0030] The present invention will be further described below.

[0031] The specific implementation of the device of the present invention is shown in the accompanying drawings. The device mainly includes: an ordinary electric soldering iron 6, a trigger link 7, a tin feeding support 9, a return spring 10 of the tin delivery support, a return spring 11 of the trigger link, a guide tube 14, Align head 15.

[0032] During the actual welding operation, the operator first passes the solder wire 8 through the gap between the trigger link 7 and the support table 17 and passes out along the guide tube 14 and the alignment head 15, and then holds the welding torch with the index finger and middle finger of the right hand Handle 6, thumb presses the handle of the trigger link 7, the upper end of the trigger link 7 rotates counterclockwise and clamps the solder wire 8 together with the support table 17 in the tin feeding bracket 9 and simultaneously drives the tin feeding bracket 9 aroun...

Abstract

The invention discloses a stepping tin feeding mechanism for an electric soldering iron. The stepping tin feeding mechanism is arranged on a common electric soldering iron, and a tin feeding function can be realized through one-hand operation. When a handle of a trigger connecting rod is pulled, the trigger connecting rod can rotate around the pivot of the electric soldering iron, the upper end of the trigger connecting rod presses a tin wire on a supporting platform, drives a tin feeding support to rotate and sequentially compresses a tin feeding support reset spring and a trigger connecting rod reset spring, and the tin wire is enabled to move forward along with a guide tube and is aligned through an alignment head; meanwhile, a leaf spring in the alignment head is pulled and pressed by a steel wire of which one end is fixed to the trigger connecting rod, so that the tin wire can be in accurate contact with a solder tip of the electric soldering iron without interruption to complete welding; when the handle of the trigger connecting rod is released, the trigger connecting rod reset spring and the tin feeding support reset spring sequentially reset the trigger connecting rod and the tin feeding support; meanwhile, the leaf spring pulled and pressed by the steel wire is reset, the leaf spring clamps the tin wire, the tin wire moves forward and extends relative to the tin feeding support and the one-time stepping tin feeding function is realized.

Description

technical field [0001] The invention relates to a stepping tin feeding mechanism for an electric soldering iron, which belongs to the technical field of electric soldering irons. Background technique [0002] Soldering irons are generally used to solder electronic components to circuit boards. After the electric soldering iron is energized, the soldering iron tip at the front end is heated to about 300 degrees Celsius, and when it meets the solder wire, it will melt the solder wire to realize the function of soldering the electronic components on the circuit board. [0003] In actual use, the staff is usually required to hold the electric soldering iron in one hand and the solder wire in the other, and the two hands cooperate to contact the soldering iron tip and the solder wire to complete the welding work. But during the operation, it will be found that the electronic components must be fixed on the circuit board to complete the soldering, which often requires the help of...
