Oil coating device for tin electroplating treatment

Abstract

The invention belongs to the technical field of tin electroplating oil coating treatment, and particularly relates to an oil coating device for tin electroplating treatment. The device comprises an oil pool, wherein a mounting plate is fixed in an inner cavity of the oil pool, a rotating shaft is rotatably arranged on the side wall of the mounting plate, the rotating shaft penetrates through the mounting plate, an output shaft of a driving motor is fixedly connected with the rotating shaft, a first disc is fixed on the side, away from the driving motor, of the mounting plate, a second disc isrotatably connected with the end, away from the first disc, of the rotating shaft, connecting rods are rotatably arranged on the side wall of the second disc in the circumferential direction of the second disc at equal distances, and a mounting disc is fixed on the end, away from the second disc, of each connecting rod. According to the device, an electric push rod is controlled to contract by a controller, the electric push rod drives a connected sliding seat to move in a direction close to the mounting disc, and the sliding seat pulls and holds a connected first spring, so that a connected gripping hand synchronously contracts towards the middle part, then the outer diameter of the gripping hand is reduced, the gripping hand can easily enter a workpiece, and the gripping hand can conveniently and quickly enter the workpiece.

Description

technical field [0001] The invention belongs to the technical field of electroplating tin oiling treatment, in particular to an oiling device for electroplating tin treatment. Background technique [0002] Tin coating has been widely used in the electronics industry as a protective and solderable coating for electronic components, wires, printed circuit boards and integrated circuit blocks due to its excellent corrosion resistance and solderability. [0003] The application of electroplating tin is very extensive. Tin has the advantages of corrosion resistance, discoloration resistance, non-toxicity, easy brazing, softness, low melting point and good ductility. Dense, uniform and continuous alloy coating. [0004] Although the electroplating tin solutions are different, the electroplating process is basically the same. The basic process is divided into pretreatment, electroplating, reflow, passivation and antirust oil coating; Due to the special shape of the pot-shaped wor...

[0004] Although the electroplating tin solutions are different, the electroplating process is basically the same. The basic process is divided into pretreatment, electroplating, reflow, passivation and antirust oil coating; Due to the special shape of the pot-shaped workpiece when using rust oil, a large amount of anti-rust oil will be brought out after being directly immersed in the anti-rust oil, resulting in a waste of anti-rust oil, and it is necessary to manually immerse the workpiece in the anti-rust oil, which may easily cause leakage of the workpiece. Coated, thus affecting the service life of the workpiece,
