Description

TECHNICAL FIELD

[0001] The present application relates to the field of electroplating equipment, in particular to a part hoisting device in an electroplating process. BACKGROUND

[0002] Hanging plating, also commonly known as hanging plating, is a process in which workpieces are clamped on hangers, suitable for large parts, and each batch can be plated with a small number of products, and the thickness of the plating layer is more than 10 microns. For example, the bumper of an automobile, the handle of a bicycle, etc.

[0003] At present, the traditional electroplating process generally adopts the method of static hanging plating, and the electrode plate for electroplating is hung at both ends of the electroplating tank. The ionization and deposition of metal ions will cause the plating layer to be uneven in thickness. The difference in thickness between the position far from the electrode plate and the position close to the electrode plate will cause the part to have a slight change in radial shape, thereby affecting the distribution of the electric field around the part when it is installed on the product. With the improvement of product quality requirements, the traditional static hanging method has been unable to meet the technical requirements. SUMMARY

Meanwhile, the mounting ball 25 slides in the mounting groove 26, which supports the mounting ball 25 and also limits the rotation of the mounting frame 2. The guide rail 1 is fixed with a guide plate 27 at the discharge end, and the guide plate 27 is inclined downward from the side of the guide rail 1 away from the guide rail 1. The wall below the guide rail 1 is fixed with a sliding rail 28 parallel to the corresponding guide rail 1, and the sliding rail 28 is used to receive the mounting ball 25 falling from the guide plate 27. In order to prevent the mounting ball 25 from separating from the guide plate 27, the sliding rail 28 is provided with an arc-shaped clamping groove. When the mounting block separates from the driving chain 23, the mounting ball 25 moves from the mounting groove 26 to the sliding rail 28 through the clamping groove on the guide plate 27 under the action of gravity.

The upper end of the auxiliary plate 31 is fixed with a transition plate 32 arranged horizontally, and the transition plate 32 is located above the driving chain 23. The auxiliary plate 31 and the transition plate 32 are both provided with clamping grooves for guiding the mounting ball 25, preventing the mounting ball 25 from separating from the auxiliary plate 31 or the transition plate 32 during the movement of the mounting ball 25 on the auxiliary plate 31 and the transition plate 32, and the sawtooth on the mounting block engages with the driving chain 23 when the mounting ball 25 separates from the transition plate 32.
