Gantry tank immersion type production line overturning jig structure

Abstract

The invention discloses a gantry tank immersion type production line overturning jig structure. The gantry tank immersion type production line overturning jig structure comprises a crane frame and a fly bar arranged on the crane frame. The fly bar comprises a main bar, a secondary bar, main bar lifting rods connected with the two ends of the main bar to drive the main bar to move in the vertical direction, and secondary bar lifting rods connected with the two ends of the secondary bar to drive the secondary bar to move in the vertical direction. The main bar lifting rods are provided with secondary bar limiting grooves used for preventing the secondary bar from moving relative to the main bar lifting rods in the horizontal direction, and the secondary bar limiting grooves are matched withthe ends of the secondary bar. The main bar is provided with a hook for hanging a product. The secondary bar is provided with an overturning assembly for pushing the product to turn up and down aroundthe hook. Through the relative movement between the secondary bar and the main bar when the fly bar is immersed in work liquid and taken away from the work liquid, the secondary bar drives the overturning assembly to overturn the product hung on the main bar, and uncoating / non-plating, rusting, color differences and other phenomena of a blind hole in the product caused by bubbles or accumulatingliquid are prevented.

Description

technical field [0001] The invention belongs to the field of electroplating equipment, and in particular relates to a flip hanger structure for a gantry tank dipping production line. Background technique [0002] At present, many workpieces have blind holes. When electroplating equipment is used to electroplate workpieces with blind holes, in the process of bath immersion chemical treatment, if the blind holes are downward, the workpiece is placed in the working solution At this time, the air in the blind hole cannot be completely exhausted, and the air bubbles will accumulate on the upper side of the blind hole, causing the working fluid to be unable to fully contact the part where the air bubbles accumulate in the blind hole, resulting in no coating / plating, rust, color difference, etc. ; If the blind hole is upward, when the workpiece is taken out from the working fluid, the working fluid in the blind hole cannot flow out, and the residual liquid will remain in the blind ...

[0002] At present, many workpieces have blind holes. When electroplating equipment is used to electroplate workpieces with blind holes, in the process of bath immersion chemical treatment, if the blind holes are downward, the workpiece is placed in the working solution At this time, the air in the blind hole cannot be completely exhausted, and the air bubbles will accumulate on the upper side of the blind hole, causing the working fluid to be unable to fully contact the part where the air bubbles accumulate in the blind hole, resulting in no coating / plating, rust, color difference, etc. ; If the blind hole is upward, when the workpiece is taken out from the working fluid, the working fluid in the blind hole cannot flow out, and the residual liquid will remain in the blind hole, causing the reaction time between the blind hole and the working fluid to be too long, causing the working fluid to corrode the workpiece, At the same time, the working fluid will be brought into the next process to affect the next process, resulting in workpiece defects
