Electroplated crown block and lifting device thereof

Abstract

The invention provides an electroplated crown block and a lifting device thereof. The lifting device of the electroplated crown block comprises a bracket, a lifting frame, a guide mechanism and a lifting driving mechanism, wherein the lifting frame is positioned on one side of the bracket and can lift up and down along the bracket; the guide mechanism is arranged between the bracket and the lifting frame and connected with the bracket and the lifting frame, so that the lifting frame can be guided during lifting along the bracket; the lifting driving mechanism is connected with the lifting frame and can drive the lifting frame to lift up and down along the bracket. According to the lifting device of the electroplated crown block, the vertical status of the lifting frame can be kept through the guide mechanism arranged on the lifting device, so as to guarantee the stable lifting up and down of the lifting frame, equipment fault due to staggering of a hook on the lifting frame and a clamp slot in a liquid medicine tank can be avoided, the tipping possibility of the lifting device can be eliminated, in addition, the occurrence of an accident that a circuit board is damaged due to tipping of the lifting device can also be avoided.

Description

technical field [0001] The invention relates to the field of printed circuit board production and manufacturing, in particular to a lifting device for an electroplating crane and an electroplating crane including the lifting device. Background technique [0002] Generally, the electroplating process is relatively long and requires multiple treatments and many potion tanks. For example, during electroplating in the circuit board industry, the circuit board goes through feeding → bulking tank → double water washing → potassium permanganate → neutralization → double water washing → degreasing → double water washing → micro-etching → double water washing → activation → double water washing → sinking copper →Double water washing→loading and other processes, the circuit boards need to be placed in these chemical tanks for processing in sequence. Electroplating cranes are used in the industry to place circuit boards. There are two types of electroplating cranes, namely: single ar...

AI Technical Summary

Problems solved by technology

The gantry crane is expensive and takes up a lot of space, and because the gantry crane has double tracks, it is easy to hit the people next to the crane, and the crane poses a safety hazard to the staff who take the medicine during the walking process; and the one-armed Compared with the gantry crane, the overhead crane takes up less space and is relatively cheap, so it is favored by most enterprises

However, the stability of the one-armed crane is poor during use. The chain-type lifting structure is difficult to ensure that the lifting frame is in a vertical state continuously, and the hook on the lifting frame is easy to stagger with the slot of the medicine tank when it is lowered. malfunctions and causes the hoist to tip over
