Description

Technical Field

[0001] This utility model relates to the field of tin-based alloy processing, and in particular to a corrosion-resistant post-treatment device for tin-based alloy composite coatings. Background Technology

[0002] In modern industrial production, surface treatment technology for metallic materials plays a crucial role in improving their corrosion resistance, wear resistance, and aesthetics. Tin-based alloy composite coatings are widely used in electronics, automotive, and aerospace industries due to their excellent corrosion resistance, electrical conductivity, and solderability. However, after preparation, tin-based alloy composite coatings may still have some microscopic defects on their surface, such as pores and cracks. These defects can affect the coating's corrosion resistance, making it more susceptible to corrosion in harsh environments, thus reducing product lifespan and reliability.

[0003] Traditional corrosion-resistant post-treatment methods mainly include chemical treatment, electrochemical treatment, and heat treatment. Chemical treatment involves contacting a chemical reaction solution with a tin-based alloy. After the reaction, the tin-based alloy is removed, leaving a liquid residue that needs to be allowed to dry naturally, which takes a long time.

[0004] Therefore, it is necessary to propose a corrosion-resistant post-treatment device for tin-based alloy composite coatings to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a post-treatment device for corrosion resistance of tin-based alloy composite coatings, solving the problems of traditional corrosion resistance post-treatment methods, which mainly include chemical treatment, electrochemical treatment, and heat treatment. Chemical treatment involves contacting a chemical reaction solution with the tin-based alloy, but after the reaction, the tin-based alloy leaves residual liquid, which requires natural drying, resulting in a long processing time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant post-treatment device for tin-based alloy composite coatings, comprising:

[0007] Processing box;

[0008] A collection basket, wherein the collection basket is lifted and positioned inside the processing box;

[0009] The collection basket has side grooves on both sides for liquid discharge, and there are multiple side grooves, which are evenly spaced along the height of the collection basket.

[0010] Both sides of the top of the processing box are fixed with L-shaped air boxes, and the opposite side of the two L-shaped air boxes corresponds magnetically with the side groove of the collection basket.

[0011] Preferably, the top of both sides of the collection basket is fixed with a connecting plate, and the two connecting plates are provided with openings for the top of the corresponding L-shaped bellows to pass through;

[0012] An electric push rod is embedded in the top of the processing box, and the bottom of the connecting plate is connected to the top of the electric push rod.

[0013] Preferably, each of the two L-shaped bellows has an air outlet at one end, and an electromagnet is provided on the outside of the air outlet, the electromagnet being embedded in the end of the L-shaped bellows.

[0014] A magnetic block is provided on the outside of the side groove. The magnetic block is embedded in the outside of the processing box. When the electromagnet is energized, it is magnetically connected to the corresponding magnetic block.

[0015] Preferably, support legs are fixed on both sides of the processing box;

[0016] The bottom of the collection basket has multiple bottom grooves, and the top of the processing box has a reaction tank into which the collection basket can extend, and the reaction tank is filled with reaction liquid.

[0017] Preferably, a fan is fixed to the outside of the processing box, and the fan is connected to the air outlet through an air duct.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. In this utility model, after the tin-based alloy and the reaction liquid have completed their reaction, the collecting basket will rise, causing the tin-based alloy and the reaction liquid to separate. At the same time, excess reaction liquid will be discharged from the side groove and the bottom groove. Furthermore, when the collecting basket rises, the side grooves on both sides of the collecting basket will contact the end of the L-shaped bellows. At this time, the electromagnet is energized, causing the end of the L-shaped bellows to be magnetically connected to the outside of the collecting basket, fixing the collecting basket at this height and providing a fixed support for the collecting basket, thereby enhancing the stability of the structure. At the same time, the air force generated by the fan will be discharged from the air outlet and enter the inside of the collecting basket to dry the tin-based alloy inside, accelerating the evaporation of the reaction liquid.

[0020] 2. At the same time, as the collection basket rises, the end of the L-shaped bellows can be adsorbed by the side grooves at different heights, thereby drying the tin-based alloy at different heights and improving the stability of the collection basket as it rises.

The reaction tank 8 is filled with reaction liquid, and the size of the reaction tank 8 matches the size of the collection basket 6.

[0027] The collection basket 6 has side grooves 9 on both sides for liquid discharge. Multiple side grooves 9 are provided and are evenly spaced along the height of the collection basket 6. The tin-based alloy to be processed can be placed inside the collection basket 6. When the collection basket 6 descends, it can carry the tin-based alloy into the reaction tank 8 to come into contact with the reaction liquid.

[0028] L-shaped air boxes 10 are fixed on both sides of the top of the treatment box 1. The two L-shaped air boxes 10 are magnetically attached to the side grooves 9 of the collection basket 6 on opposite sides. Multiple bottom grooves 7 are provided at the bottom of the collection basket 6.
