Description

Technical Field

[0001] This utility model relates to the field of electroplating rack technology, specifically to an electroplating rack with shielding. Background Technology

[0002] Electroplating is a surface treatment technology that uses the principle of electrolysis to deposit a metal or alloy coating on the surface of a solid workpiece. Its core purpose is to endow the workpiece with special properties through electrochemical reactions, such as corrosion resistance, wear resistance, conductivity, and aesthetics.

[0003] In the electroplating process, shielding refers to the technical means of insulating and covering specific areas of a workpiece to prevent electroplating deposition. When performing surface electroplating on a workpiece (plunger), shielding the inside of the plunger is quite difficult, and the number of workpieces processed at a time is affected when shielding the ends of the workpiece. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: including a conductive beam 1, a hanger 2 connected to the bottom end of the conductive beam 1, multiple top rods 3 and drag rods 4 connected between the inner sides of the hanger 2, a copper plate 5 connected to the top end of the conductive beam 1, a connecting bolt 51 connected to one side of the copper plate 5, a connecting nut 8 connected to the bottom end of the top rod 3, a top point 9 connected to the inner side of the connecting nut 8, an upper shielding plate 10 connected to one end of the top point 9, a conductive seat 11 connected to the top end of the drag rod 4, and a lower shielding plate 12 connected to the outer surface of the conductive seat 11;

[0019] Reference Figure 1As shown in the middle section, the power control unit 7 and the connecting frame 6 are connected to both sides of the copper plate 5 by connecting bolts 51. Through the connection of 51, the connecting frame 6 and the power control unit 7 can be connected to the copper plate 5. The conductive beam 1 and the hanger 2 can be hoisted through the hanging hole on one side of the connecting frame 6. The power control unit 7 includes an axial current compensator, a pulse modulation module and a distributed current sensor, etc. Since it is a conventional setting, it is not described in detail in the manual.

[0020] Reference Figure 3 As shown, the top of the tow rod 4 is provided with a groove, the bottom of the conductive seat 11 is located in the groove, and a positioning bolt 111 is connected to the inner side. The tow rod 4 and the conductive seat 11 are electrically connected. The conductive seat 11 and the tow rod 4 are connected through the connection of the positioning bolt 111. The workpiece 13 is located in the conductive seat 11. The tow rod 4 is electrically connected to the power control unit 7 as the cathode.

[0021] A workpiece 13 is connected between the conductive base 11 and the tip 9. The bottom end of the tip 9 extends into the workpiece 13 for positioning, while the upper shielding plate 10 naturally slides down to the top of the workpiece 13.

[0022] The conductive beam 1, copper plate 5, and hanger 2 are electrically connected. The hanger 2 is an auxiliary anode, which facilitates the replenishment of ions in the electrolyte during electroplating. The top 9, upper shielding plate 10, and lower shielding plate 12 are made of PVC.

[0023] The implementation principle of this application is as follows: When using this utility model, the workpiece 13 is placed in the conductive base 11, and then the tip 9 is rotated by connecting the nut 8, so that the tip of the tip 9 extends into the interior of the workpiece 13, thereby fixing the workpiece 13. The upper shielding plate 10 slides down along the tip 9 to the top of the workpiece 13, while the lower shielding plate 12 is located at the bottom of the workpiece 13. The setting of the upper shielding plate 10 and the lower shielding plate 12 effectively solves the problem of uneven distribution of electric lines, thereby improving the quality and uniformity of the plating layer of the workpiece 13. The copper plate 5 supplies power to the conductive beam 1, so that the hanger 2 forms a positive pole, and the drag bar 4 is connected to another set of power supplies as a negative pole, so as to perform electroplating operation on the workpiece immersed in the solution.
