Description

technical field [0001] The invention relates to a structure of an electroplating drum, in particular to a method of separately manufacturing a large number of plate units by injection molding, then connecting the plate units laterally to form a rectangular plate, and finally connecting all the plates to each other. Combined with forming a polygonal electroplating drum with an opening, it mainly has the advantages and characteristics of simplifying the manufacturing process of the electroplating drum, reducing the manufacturing cost, improving the overall strength of the electroplating drum and improving the electroplating quality. Background technique [0002] Overview of the structure of the existing electroplating drum figure 1 As shown, it mainly includes a barrel body 10, round sealing plates 20 on both sides and an upper cover 30, wherein, in terms of the structure and processing of the barrel body 10, usually first on a large flat plastic sheet, according to the calcul...

AI Technical Summary

Problems solved by technology

[0003] 1. The overall strength of the electroplating barrel is insufficient: the body of the existing electroplating barrel is firstly drilled with a large number of through holes on the plate and then heated and bent to shape. However, after research, it is found that even if the number of through holes passes through Careful calculation, but it is an unavoidable problem that the barrel body strength of the electroplating barrel will be damaged after drilling holes on the plate. Therefore, when the electroplating barrel contains heavy electroplated objects and is used alternately with hot and cold plating solutions after continuous rotation , it is very easy to cause the deformation of the electroplating drum, and even the accident of the drum body breaking in severe cases

[0004] 2. The manufacturing cost of the electroplating barrel is too high: the through-holes on the body of the existing electroplating barrel are drilled one by one by machinery, and the subsequent manual bending and forming can only be performed after the through-holes are covered with the entire plate. The entire drilling, Bending and forming operations are extremely time-consuming and labor-intensive, and the processing speed is extremely slow, which not only causes time-consuming and labor-intensive problems, but also leads to a relatively high manufacturing cost

[0005] 3. The water permeability of the electroplating drum is poor: As mentioned above, since the number of through holes will directly affect the strength of the electroplating drum, the distribution of the through holes per unit area of ​​the plastic sheet must have its limit. However, In this way, there is another problem of poor water permeability due to too few through holes. Not only is it difficult for the electroplating solution in the electroplating tank to enter the electroplating drum, but even when the electroplating drum leaves the electroplating tank, the electroplating solution in the drum It also takes a long time to completely discharge

[0006] 4. The electroplating quality of the electroplated object is different: the inner surface of the barrel body of the existing electroplating drum is extremely flat, so the plane of the electroplated object is easily attached to and adsorbed on the inner surface of the barrel body due to the plating solution, which not only leads to electroplating on the surface of the electroplated object The effect is not uniform, which reduces the quality of the finished electroplated product. In the process of pouring out the electroplated product, the operator needs to keep pushing the material by hand to remove the electroplated product adsorbed on the inner surface of the barrel. big inconvenience
