Description

Hanging basket for electroplating

Technical Field

The invention relates to a hanging basket, in particular to a hanging basket for electroplating.

Background

Referring to fig. 1 and 2, in a conventional electroplating process, a metal block 91 to be plated on a surface of an object to be plated, such as a zinc block for zinc plating, is usually placed in a metal basket 92, the metal basket 92 is hung on a copper bar 93 to immerse the metal block 91 in a plating bath, and current is conducted to the metal basket 92 through the copper bar 93, and then the metal basket 92 conducts the current to the metal block 91, so that the metal block 91 is electrolyzed.

However, the conventional metal basket 92 includes a basket body 921 and two hooks 922 welded to both sides of the basket body 921, and is hung on the copper bar 93 by the hooks 922. Due to the fact that the contact area of the hook 922 and the copper rod 93 is small, the hook 922 is prone to being damaged when current is large, and the welding area of the hook 922 and the basket body 921 is small, so that the welding position of the hook 922 and the basket body 921 is prone to being damaged when the current is large.

Furthermore, the weight of the metal block 91 in the basket body 921 is required to press down the hook 922 to maintain stable contact with the copper rod 93 between the hook 922 and the copper rod 93, thereby maintaining stability of conduction. However, after a period of electroplating, the metal block 91 is electrolyzed and reduced in weight, so that the contact between the hook 922 and the copper rod 93 becomes unstable, and the conductive performance is reduced. And the electric current is conducted by the copper bar 93 to go to the basket body 921 via the hook 922 and then to the metal block 91, and the whole conduction path is longer, and the resistance is great, and the copper bar 93 is electrically conductive in the air simultaneously, generates heat more easily, also all can increase power consumption.

Detailed Description

Referring to fig. 3 and 4, an embodiment of a basket 100 for electroplating according to the present invention includes a basket body 1 and a hanging unit 2.

The basket body 1 has two side walls 11, two end walls 12 and a bottom wall 13. The two side walls 11 are vertically disposed and spaced apart from each other, each side wall 11 is substantially rectangular, and one of the side walls 11 has a mesh for allowing the plating bath to enter the basket body 1. The two end walls 12 are vertically disposed and oppositely connected to opposite sides of the two side walls 11 at intervals, and the height of the end walls 12 is the same as that of the side walls 11, and the width is narrow, so that the basket body 1 is oblong. The bottom wall 13 is connected to the two side walls 11 and the two end walls 12 near the bottom side, and forms an accommodating space 14 together with the two side walls 11 and the two end walls 12 for accommodating a metal block M to be electrolyzed, such as a zinc block, a nickel block, a copper block, etc. In this embodiment, a zinc block is taken as an example, and the cross section of the zinc block is generally trapezoidal. In the present embodiment, the bottom wall 13 has two inclined wall portions 131 extending from the two side walls 11 to each other in an upward direction, and each inclined wall portion 131 has an inclined surface 132 facing one of the side walls 11 for the metal block M with a trapezoidal cross section to abut against. In the present embodiment, two inclined surfaces 132 facing the two side walls 11 are formed by the two inclined wall portions 131, and the metal block M can be inserted in any direction, i.e. the inclined surface at the bottom of the metal block M can be abutted against one inclined surface 132 of the bottom wall 13, but a modified embodiment can also be implemented by forming only one inclined surface 132.

The hanging unit 2 includes a conductive metal rod 21 and two reinforcing members 22. The conductive metal rod 21 extends in a direction parallel to the sidewall 11 of the basket body 1, and has a connecting section 211 connected to the bottom wall 13, and two hanging sections 212 respectively extending from two ends of the connecting section 211 and bending upwards and extending from the ends of the connecting section towards each other. The ends of the two hanging sections 212 are used to electrically connect conductive elements on a plating bath (not shown). The two reinforcements 22 are respectively connected to the two hanging sections 212 and the basket body 1 to enhance the connection strength between the conductive metal rod 21 and the basket body 1.

In this embodiment, the basket body 1 is made of titanium, and the conductive metal rod 21 is made of copper rod coated with titanium layer. The connecting section 211 of the conductive metal rod 21 is fixed to the bottom wall 13 by welding, the connecting section 211 is located between and connected to the two inclined wall portions 131, and the conductive metal rod 21 passes through the two end walls 12.

The conductive metal bar 21 is mostly located in the plating bath during the plating process, and can reduce heat generation by cooling the plating bath to reduce power consumption, and can be resistant to corrosion by the coated titanium metal layer. Moreover, since the conductive metal rod 21 is welded to the bottom wall 13 along the length direction of the bottom wall 13, the area of the conductive metal rod 21 for conducting current with the basket body 1 can be increased, and the weld joint damage caused by excessive current concentration can be avoided. Furthermore, since the conductive metal rod 21 is welded to the bottom wall 13, stable contact can be maintained, and current can be conducted stably. In addition, in the electroplating process, the bottom inclined surface of the metal block M is in contact with the inclined surface 132 of the bottom wall 13, so that the conduction efficiency can be increased, and the current of the conductive metal rod 21 is directly conducted to the metal block M through the bottom wall 13, so that the conduction distance of the current is greatly shortened, the overall resistance is small, and the power consumption can be reduced. Compared with the conventional electroplating process in which the metal basket 92 (see fig. 1) is hung on the copper rod 93 by the hook 922, the present embodiment can save about 15-30% of electric energy.

To sum up, connect in the diapire 13 of this basket body 1 and have the electrically conductive function of holding concurrently through electrically conductive metal rod 21, can not only save power consumption, and can avoid like the easy problem of damaging of couple 922 and basket body 1 welding department of current metal basket 92, increase life.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
