Tin immersion method and tin immersion device

Abstract

The invention discloses a tin immersion method and a tin immersion device. The tin immersion method comprises the following steps: a part to be subjected to tin immersion is fixed to a clamping element of a movement mechanism; a distance measurement module measures to obtain a distance h1 between the part to be subjected to tin immersion and the liquid level of molten tin in a tin furnace, and sends a measurement result to a control mechanism; the control mechanism calculates to obtain a height L needing to be descended, of the movement mechanism, according to the measurement result, and sends an instruction of descending the height L to the movement mechanism; and the movement mechanism descends the height L and immerses the part to be subjected to tin immersion in the molten tin. According to the tin immersion method and the tin immersion device, the liquid level of the molten tin is stable and free from fluctuation, and no temperature change and less liquid level oxidization are achieved; detection for the molten tin in the tin furnace can be realized before tin immersion every time, without the influence of the liquid level drop of the molten tin in the tin furnace; and the tin immersion method and the tin immersion device are high in detection speed and accuracy, free from influence on tin immersion rhythm, and capable of increasing the production efficiency.

Description

technical field [0001] The invention belongs to the field of tin immersion technology, and in particular relates to a tin immersion method and a tin immersion device. Background technique [0002] With the economic development, especially the rapid development of the electronic industry, more and more products need tin immersion treatment to prevent oxidation or facilitate soldering. But at the same time, it also puts forward higher requirements for the precision of immersion tin. For example, wire materials such as enameled wires, coaxial cables, and flat cables have high requirements for immersion tin precision, which must meet the requirements of good immersion tin effect and consistent size. [0003] At present, during the tin immersion process, part of the tin liquid will be taken away by the dipped parts, and at the same time, part of the tin will be oxidized. Therefore, the height of the tin liquid level in the tin furnace from the tin furnace installation table is co...

AI Technical Summary

Problems solved by technology

[0004] (1) After the tin liquid is scooped up, the temperature of the tin liquid surface will drop to a certain extent, which will affect the tin immersion effect;

[0005] (2) After the tin liquid is scooped up, the liquid surface will shake to a certain extent, which will affect the precision of tin immersion;

[0006] (3) After the tin liquid is scooped up, due to the influence of tension, the tin liquid level will be higher than the tin spoon, and will slowly drop, affecting the precision of tin immersion;

[0007] (4) It takes a certain amount of time to scoop the tin solution. During this process, the tin will be oxidized to a certain extent, which will affect the effect of tin immersion
