Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of circuit board production, concretely relates to a chemical nickel palladium gold production line with stable material moving. BACKGROUND

[0002] In the production process of the printed circuit board, it needs to be subjected to chemical nickel gold plating surface treatment process, that is, a nickel gold layer with stable color, good brightness, smooth plating layer and good solderability is deposited on the surface of the printed circuit board. In the chemical nickel gold plating process, the printed circuit board needs to be installed in a hanger, and then the hanger is hung on a crown of the chemical nickel gold plating production line, and finally the hanger is placed on a support frame installed on a medicine cylinder by the crown, so that the printed circuit board mounted in the hanger is immersed in the medicine cylinder to realize nickel palladium gold plating treatment.

[0003] The prior art patent No. CN216514122U discloses a chemical nickel palladium gold production line. The above-mentioned patent avoids the collision between the hollow barrel and the nickel plating mechanism during the lowering of the basket by supporting the basket with the support frame and setting the second buffer plate. After the basket is retracted, the support frame loses pressure and slowly floats up to reset in cooperation with the hollow barrel to facilitate the next lowering of the basket. This effectively avoids the shaking of the basket during lowering and the collision with the inner wall of the nickel plating mechanism. However, in actual use, the following problems still exist: in practice, the production line is unstable during processing by the crane mechanism supporting the basket one by one. This leads to poor nickel palladium gold plating treatment of the circuit boards inside the basket and affects the processing effect. Moreover, the support frame cannot support baskets of different sizes, which limits the application range of the production line and reduces the use range of the production line.

[0004] Therefore, there is a need for a chemical nickel palladium gold production line with stable material moving to solve the problems of unstable movement of the basket and the inability of the support frame to support baskets of different sizes in the prior art. UTILITY MODEL CONTENTS
