For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] As Figures 1 to 2 shown, the gold-removing and tin-plating workbench of the present utility model includes: a base 1 in which a gold-removing furnace 2 and a tin-plating furnace 3 are placed; a lifting platform 4 on which a gold-removing station 41 corresponding to the gold-removing furnace 2 and a tin-plating station 42 corresponding to the tin-plating furnace 3 are configured.

[0025] See Figure 1 、 Figure 2, the first pin perforation 411 provided on the lifting platform 4 is for the pins of the electrical components to be de-gilded to enter, and the second pin perforation 421 is for the pins of the electrical components to be tinned to enter. Multiple groups of the first pin perforation 411 and the second pin perforation 421 can be provided, so that the workbench of the present application can simultaneously perform de-gilding and tinning operations on several electrical components respectively, improving the efficiency of de-gilding and tinning of the electrical components.

[0026] See Figure 2 , in the initial state, under the action of the elastic member 5, the lifting platform 4 is pushed towards the side away from the base 1 to a stationary state.

[0027] When de-gilding and tinning the electrical components, the pins of the electrical components to be de-gilded are placed into the first pin perforation 411, and the pins of the electrical components to be tinned are placed into the second pin perforation 421. At this time, the pins of the electrical components located at the de-gilding station 41 do not extend into the de-gilding furnace 2, and the pins of the electrical components located at the tinning station 42 do not extend into the tinning furnace 3; thereafter, the staff can press down the lifting platform 4 to overcome the elastic force of the elastic member 5, so that the pins of the electrical components located at the de-gilding station 41 extend into the de-gilding furnace 2, and the pins of the electrical components located at the tinning station 42 extend into the tinning furnace 3, realizing the de-gilding operation on the electrical components at the de-gilding station 41 and the tinning operation on the electrical components at the tinning station 42. Thereafter, the extrusion on the lifting platform 4 is released, and under the action of the elastic member 5, the lifting platform 4 resets to the initial state. At this time, at least two electrical components that have completed the de-gilding and tinning operations can be removed and classified and placed; through this kind of setting, it can avoid the shaking of the de-gilding furnace 2 and the tinning furnace 3 resulting in the overflow of the tin wave, improving the stability of the de-gilding and tinning operations on the electrical components. At the same time, the present application can insert the pins of multiple electrical components into the first pin perforation 411 and the second pin perforation 421 to realize the simultaneous de-gilding and tinning operations on several electrical components synchronously, improving the processing efficiency of the electrical components.

When the timing of the timer 7 ends, the buzzer alarm can alarm in time to prompt the staff to release the downward pressure on the lifting platform 4. With this setting, the efficiency of the staff in removing gold and tinning the electrical components can be improved, and the processing efficiency of the electrical components can be improved.
