Description
- This application claims priority to Taiwanese Patent Application No. 109106172, filed on Feb. 26, 2020.
- The disclosure relates to a basket, and more particularly to an electroplating basket.
- Referring to
FIGS. 1 and 2 , anelectroplating metal block 91, such as a zinc block for galvanizing, is generally disposed within ametal basket 92. Themetal basket 92 is hung to acopper rod 93, and is immersed into an electrolyte bath. Thecopper rod 93 conducts an electric current to themetal basket 92. Themetal basket 92 passes the electric current to theelectroplating metal block 91 so that theelectroplating metal block 91 can be electrolyzed. - The
metal basket 92 has abasket body 921 and twohooks 922 welded to thebasket body 921. Thehooks 922 are attached to thecopper rod 93. Because eachhook 922 has a small area in contact with thecopper rod 93, when the electric current is large, thehooks 922 are easily damaged. Further, the welded joint between eachhook 922 and thebasket body 921 has small contact surface area and is prone to damage due to the large electric current. - In addition, stability of contact pressure between the
hooks 922 and thecopper rod 93 must rely on the weight of theelectroplating metal block 91 within thebasket body 921 in order to maintain stable electric conduction. However, after a period of electrolysis, the weight of theelectroplating metal block 91 can be reduced, and the contact pressure between thehooks 922 and thecopper rod 93 can become instable and decrease the electric conducting effect. Moreover, because the electric current flows to theelectroplating metal block 91 through thehooks 922 and thebasket body 921, the path of electric conduction is long, and the electrical resistance thereof is large. As thecopper rod 93 conducts electricity in air, it is easy to generate heat, which increases energy consumption. - Therefore, the object of this disclosure is to provide an electroplating basket that can alleviate at least one of the drawbacks of the prior art.
- According to the disclosure, an electroplating basket includes a basket body and a hanging unit.
- The basket body has two upright side walls spaced apart from each other, two upright end walls spaced apart from each other and interconnected with the upright side walls, and a bottom wall connected to the upright side walls and the upright end walls. The upright side walls, the upright end walls, and the bottom wall cooperatively define an accommodating space.
- The hanging unit includes a conductive metal rod. The conductive metal rod has a connection portion that extends along the upright side walls and that is disposed beneath and connected to the bottom wall, and two hanging portions extending respectively and upwardly from two opposite ends of the connection portion along the upright end walls and bending sidewards away from the upright end walls.
- Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment(s) with reference to the accompanying drawings, of which:
-
FIG. 1 illustrates an existing metal basket hung to a copper rod; -
FIG. 2 is a side sectional view ofFIG. 1 ; -
FIG. 3 illustrates an electroplating basket according to an embodiment of the disclosure; and -
FIG. 4 is a side sectional view ofFIG. 3 . -
FIGS. 3 to 4 illustrate anelectroplating basket 100 according to an embodiment of the disclosure. Theelectroplating basket 100 includes abasket body 1 and ahanging unit 2. - The
basket body 1 has twoupright side walls 11, twoupright end walls 12, and abottom wall 13. Theupright side walls 11 are spaced apart from each other. Eachupright side wall 11 is shaped in a rectangular form and has a plurality of perforations for entry of an electrolyte into thebasket body 1. Theupright end walls 12 are spaced apart from each other and are each connected to one end of eachupright side wall 11. Theupright end walls 12 are as high as theupright side walls 11. Eachupright end wall 12 has a length shorter than that of eachupright side wall 11, so that thebasket body 1 is oblong. Thebottom wall 13 is connected to theupright side walls 11 and theupright end walls 12. Theupright side walls 11, theupright end walls 12, and thebottom wall 13 cooperatively define anaccommodating space 14 to receive an electroplating metal block (M), such as a zinc, nickel, or copper block, for plating. In this embodiment the electroplating metal block is the nickel block having a trapezoidal cross section. Thebottom wall 13 has twoinclined wall portions 131 that extend upwardly and respectively from bottom ends of theupright side walls 11, and that intersect each other and are inclined with respect to theupright side walls 11. Eachinclined wall portion 131 has an innerinclined surface 132 that is inclined with respect to one of theupright side walls 11. The innerinclined surface 132 is used to contact and support a sloping face of the electroplating metal block (M). Because there are two innerinclined surfaces 132 in this embodiment, regardless of whatever one of the sloping faces of the plating metal block (M) is used as a leading end for insertion into the metal block (M), the metal block can certainly be placed in contact with the innerinclined surface 132 of one of theinclined wall portions 131. However, in other embodiments, thebottom wall 13 of thebasket body 1 can have only one innerinclined surface 132. - The hanging
unit 2 includes aconductive metal rod 21 and tworeinforcement members 22. Theconductive metal rod 21 is disposed parallel with theupright side walls 11, and has aconnection portion 211 and two hangingportions 212. Theconnection portion 211 extends along theupright side walls 11 and is disposed beneath and connected to thebottom wall 13. The hangingportions 212 extend respectively and upwardly from two opposite ends of theconnection portion 211 along theupright end walls 12 and bend sidewards away from theupright end walls 12. The hangingportions 212 can be hung to a copper rod (not shown) that is electrically connected to a conductive member (not shown) of an electroplating tank (not shown). Eachreinforcement member 22 is connected to one of the hangingportions 212 of theconductive metal rod 21 and one of theupright end walls 12 of thebasket body 1 to reinforce connection strength of theconductive metal rod 21 to thebasket body 1. - In this embodiment, the basket body is made from titanium. The
conductive metal rod 21 is a copper rod with an outer surface covered by a titanium coating. - The
connection portion 211 of theconductive metal rod 21 is welded to thebottom wall 13 of thebasket body 1. In particular, theconnection portion 211 is disposed between and welded tobottom sides 133 of saidinclined wall portions 131 of thebottom wall 13. In addition, theconnection portion 211 of theconductive metal rod 21 extends through theupright end walls 12. - In use, most parts of the
conductive metal rod 21 are immersed in and cooled by the electrolyte to reduce heat dissipation and energy consumption. Further, the titanium coating covering the outer surface of theconductive metal rod 21 can resist corrosion. Theconnection portion 211 of theconductive metal rod 21 is welded to thebottom wall 13 along an entire length of thebottom wall 13. Therefore, the contact surface area of the welded joint between theconductive metal rod 21 and thebasket body 1 for conducting electricity can be increased, and excessive current concentration, which can damage the welded area, can be avoided. Particularly, because theconnection portion 211 of theconductive metal rod 21 is welded to bothbottom sides 133 of theinclined wall portions 131, the welded joint between theconductive rod 21 and thebasket body 1 has an increased contact surface area for electric conduction, thereby reducing the risk of damage to the welded joint. As theconnection portion 211 of theconductive metal rod 21 is intimately welded to thebottom wall 13, the contact surface area at the welded joint is stable, thereby stabilizing electrical conduction. During plating, contact between the sloping face of the electroplating metal (M) and the innerinclined surface 132 can increase conductivity. An electric current passing theconductive metal rod 21 can directly flow to the electroplating metal (M) through thebottom wall 13. Therefore, the electric conduction path can be shortened, and an overall electrical resistance of theelectroplating basket 100 can be reduced, thereby decreasing energy consumption. Compared to the existing electroplating basket 92 (seeFIG. 1 ), theelectroplating basket 100 is able to provide energy saving of 15% to 30%. - By virtue the
conductive metal rod 21 having the hanging portions to hang thebasket body 1 and the connection portion welded to thebottom wall 131 of thebasket body 1 to transmit electricity to the electroplating metal block through the bottom wall, energy consumption can be saved, and the risk of damage to the welded joints can be reduced. - In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment. It will be apparent, however, to one skilled in the art, that one or more other embodiments maybe practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,” “an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects, and that one or more features or specific details from one embodiment may be practiced together with one or more features or specific details from another embodiment, where appropriate, in the practice of the disclosure.
- While the disclosure has been described in connection with what is considered the exemplary embodiment, it is understood that this disclosure is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
