Description

Hanging basket for electroplating

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

1 and 2, in the existing electroplating process, the metal block 91 of the metal to be plated on the surface of the object, such as the zinc block for galvanizing, is usually placed in the metal basket 92, and then the metal basket 92 is hung on the The copper rod 93 immerses the metal block 91 in the plating bath, and the copper rod 93 conducts current to the metal basket 92, and then the metal basket 92 conducts the current to the metal block 91 to electrolyze the metal block 91.

However, the existing metal basket 92 includes a basket body 921 and two hooks 922 welded on both sides of the basket body 921 respectively, and are hung on the copper rod 93 by the hooks 922. Because the contact area between the hook 922 and the copper rod 93 is small, the hook 922 is easily damaged when the current is large, and the welding area between the hook 922 and the basket body 921 is also small, so that the welding place between the hook 922 and the basket body 921 is It is also easily damaged when the current is large.

Furthermore, between the hook 922 and the copper rod 93, the weight of the metal block 91 in the basket body 921 is required to press the hook 922 downward to maintain stable contact with the copper rod 93, thereby maintaining the stability of conduction. However, after a period of electroplating, the metal block 91 is electrolyzed and the weight is reduced, which will make the contact between the hook 922 and the copper rod 93 more unstable, resulting in a decrease in conductivity. Moreover, the current is conducted from the copper rod 93 through the hook 922 to the basket body 921 and then to the metal block 91. The overall conduction path is longer and the resistance is large. At the same time, the copper rod 93 conducts electricity in the air, which is easier to generate heat, which will also increase power consumption. .

Therefore, one of the objects of the present invention is to provide a hanging basket for electroplating which can solve the aforementioned problems.

The basket has two side walls, two end walls, and a bottom wall. The two side walls are upright and spaced and opposed to each other. The bottom wall is connected to the two side walls and the two end walls close to the bottom side, and forms an accommodating space together with the two side walls and the two end walls. The hanging unit includes a conductive metal rod that extends in a direction parallel to the side wall of the basket body, and has a connecting section connected to the bottom wall, and two connecting sections are bent upwards from both ends of the connecting section. And the end of the bending extension of the hanging section.

In some embodiments, the basket is made of titanium, and the conductive metal rod is made of a copper rod covered with a titanium layer.

In some embodiments, the connecting section of the conductive metal rod is connected and fixed to the bottom wall by welding.

In some implementation aspects, the hanging unit further includes two reinforcing members, and the two reinforcing members are respectively connected to the two hanging sections and the basket.

The problem of easy damage.

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

The basket 1 has two side walls 11, two end walls 12 and a bottom wall 13. The two side walls 11 are arranged upright and spaced apart from each other. Each side wall 11 is generally rectangular, and one of the side walls 11 has a mesh for the plating bath to enter the basket 1. The two end walls 12 are arranged upright and are connected to opposite sides of the two side walls 11 at intervals opposite to each other. The end walls 12 have the same height as the side walls 11 and a narrow width, so that the basket body 1 is elongated. The bottom wall 13 is connected to the two side walls 11 and the two end walls 12 near the bottom side, and together with the two side walls 11 and the two end walls 12 forms an accommodating space 14 for accommodating the metal block to be electrolyzed M, such as zinc block, nickel block, 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 this embodiment, the bottom wall 13 has two oblique wall portions 131 extending obliquely upward from the two side walls 11 to each other, and each oblique wall portion 131 has an inclined surface 132 facing one of the side walls 11 A metal block M with a trapezoidal cross-section is provided for abutment. In this embodiment, the two inclined wall portions 131 form two inclined surfaces 132 facing the two side walls 11, and the metal block M can be inserted in any direction to make the inclined surface of the bottom of the metal block M abut against the One of the inclined surfaces 132 of the bottom wall 13 may be implemented, but in a modified embodiment, only one inclined surface 132 is formed.

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 side wall 11 of the basket body 1 and has a connecting section 211 connected to the bottom wall 13, and two connecting sections 211 are bent upwards and extend toward each other. The hanging section 212 extending in reverse bending. The ends of the two hanging sections 212 are used to electrically connect conductive elements on the electroplating tank (not shown). The two reinforcing members 22 are respectively connected to the two hanging sections 212 and the basket body 1 to strengthen the connection strength between the conductive metal rod 21 and the basket body 1.

In this embodiment, the basket 1 is made of titanium metal, and the conductive metal rod 21 is made of a copper rod 93 covered with a titanium metal layer. The connecting section 211 of the conductive metal rod 21 is connected and fixed to the bottom wall 13 by welding.

During the electroplating process, most of the conductive metal rod 21 is located in the plating bath, which can reduce heat generation by cooling the plating bath to reduce energy consumption, and the outer titanium metal layer can resist corrosion. Moreover, since the conductive metal rod 21 is welded to the bottom wall 13 in the length direction of the bottom wall 13, the area for conducting current between the conductive metal rod 21 and the basket 1 can be increased, and the welding point can be prevented from being damaged by excessive current concentration. Especially in this embodiment, the two inclined wall portions 131 of the bottom wall 13 can be welded to the conductive metal rod 21, which can further increase the area of current conduction between the conductive metal rod 21 and the basket body 1, and greatly reduce the damage of the welding place. risk. Furthermore, since the conductive metal rod 21 is tightly welded to the bottom wall 13, a stable contact can be maintained and the current can be conducted stably. In addition, during the electroplating process, the bottom slope of the metal block M is in contact with the slope 132 of the bottom wall 13 to increase the conduction efficiency, and the current of the conductive metal rod 21 is directly conducted to the metal block M through the bottom wall 13, which greatly shortens the current conduction distance. The overall resistance is small, which can also reduce power consumption. 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, this embodiment can save about 15-30% of the electrical energy.

In summary, the conductive metal rod 21 is connected to the bottom wall 13 of the basket body 1 and has a conductive hanging function, which not only saves power consumption, but also avoids the existing metal basket 92 hook 922 and the basket. The problem of easy damage to the welding part of the body 1 increases the service life.
