The invention provides a handheld tin-controlled welding fixture for manual welding. The handheld tin-controlled welding fixture comprises a fixture body, a fixture base, a horizontal tin feeding pipe, a tin outlet and a tin inlet. A driving tin feeding wheel and a driven tin feeding wheel for horizontally oppositely clamping and feeding tin are symmetrically arranged on the tin feeding pipe; thedriving tin feeding wheel pair is meshed with a feeding rack which moves horizontally through a speed reduction transmission gear set; the feeding rack is shifted to move horizontally through a shifting handle, the position is locked through a limiting handle, and a zero position is automatically reset through a rebound spring. A horizontal guide groove or a horizontal limiting groove matched witha front-and-back shifting and limiting handle of a shell is provided with scale marks and is provided with a scale pointer; and the scale unit length of the scale marks is integral multiples of the perimeter of a manually welded single tin ring. The feeding rack is driven by the shifting handle to move horizontally, the feeding rack drives the driving tin feeding wheel and the driven tin feedingwheel to rotate through the transmission of speed reduction teeth to complete horizontal conveying of tin wires in the tin feeding pipe, the tin feeding amount can be accurately controlled, and the manual welding quality and the production efficiency are improved.
Description
technical field [0001] The invention belongs to the technical field of manual fixing devices for operation, transportation and welding, and in particular relates to a hand-held tin-controlling welding jig for manual welding that can replace the marking method to realize precise control of the amount of tin delivered. Background technique [0002] There are three welding methods for electronic components: reflow soldering, manual soldering and wave soldering. Among them, the welding completed with the help of modern machines is mainly suitable for circuit board welding occasions of mass flow plug-ins. Manual soldering is mainly suitable for soldering components with a small amount and a small number of devices, and for circuit boards that need to complete reverse soldering after wave soldering. Therefore, manual soldering is still an essential soldering method. Under the existing technology, every time a solder joint is completed by manual soldering, it has to go through thr...
