Background

The purpose of electroplating is to change the surface characteristics of solid materials, the electroplating can improve the appearance of the materials and improve the corrosion resistance, and the materials can have special surface characteristics such as magnetism, light, electricity, heat, welding and the like and other physical properties. It is generally desirable that the distribution of coating thickness over the workpiece be as uniform as possible during electrodeposition. However, the thickness distribution is not uniform due to a series of reasons such as uneven distribution of cathode current density and edge effect; how to make the plating layer as uniform as possible is the focus and core of attention of those skilled in the art of plating. The reciprocating movement and rotation of the cathode are greatly helpful to improve the uniformity of the coating. However, researchers have experimented with manual methods to periodically invert the cathode plate to improve uniformity. The 201820059318.0 patent discloses a rotary electroforming hanger for reciprocating moving cathode, which uses two motors to control the movement and rotation of the cathode plate respectively, increasing the cost, making the control more complicated and using more troublesome.

Detailed Description

The following describes an embodiment of the present invention with reference to fig. 1 and 2.

As shown in fig. 1 and fig. 2, a cathode electroplating hanger capable of rotating and moving simultaneously comprises a support base 1, a transmission screw 2, a cathode 9, a rotation preventing shaft 3, a moving frame 4, a connecting plate 5, an auxiliary support base 6, a driving motor 7, a cathode rotating belt wheel 8, a belt 10, a sliding table 11, a compression spring 12, a sliding base 13, a sliding base 14, a fixed shaft 15, a locking nut 16, a bearing 17 and a cathode shaft 18; the driving motor 7 is fixed on the auxiliary supporting seat 6; the connecting plate 5 is fixed on the movable frame 4; the cathode rotating belt wheel 8 and the cathode shaft 18 are fixed through a locking nut 16; the cathode shaft 18 is rotatably mounted in the bearing 17; one end of the belt 10 is fixed on the fixed shaft 15, the other end is fixed on the sliding seat 13, and the belt 10 and the cathode rotating belt wheel 8 are in friction transmission; the sliding seat 13 is mounted on the sliding table 11 in a linear reciprocating manner; the compression spring 12 is fixed between the sliding seat 13 and the sliding table 11; the compression spring 12 can be compressed towards the left side of the sliding seat 13; the slide base 14 is mounted on the support base 1 and the auxiliary support base 6.

The utility model discloses a theory of operation is: as shown in fig. 1, the left and right of the transmission screw 2 are respectively connected with the auxiliary supporting seat 6 and the supporting seat 1 through revolute pairs; the driving motor 7 is fixed on the auxiliary supporting seat 6 and is coaxial with the transmission screw rod 2; the movable frame 4 and the transmission screw rod 2 form screw rod transmission. When the driving motor 7 is electrified, the driving motor 7 positively drives the transmission screw rod 2 to rotate, so that the cathode rotating belt wheel 8 moves leftwards along the position shown in the figure 1; meanwhile, the cathode rotating belt wheel 8 can generate a rotating effect under the friction action of the belt 10, so that the purpose that the cathode rotating belt wheel 8 rotates and moves simultaneously is achieved; it is noted that while the cathode rotary pulley 8 is moved leftward in the position shown in fig. 1, the compression spring 12 is compressed leftward in the slide holder 13 in the position shown in fig. 1. When the driving motor 7 rotates reversely, the cathode rotating belt wheel 8 returns along the original path; at the same time, the compression spring 12 is deformed to the right, and the slide holder 13 is slid to the right, thereby pulling the belt 10 to rotate the cathode rotary pulley 8. If only the cathode rotary pulley 8 is required to move, it is only necessary to reverse the drive motor 7 in the position shown in fig. 1, so that the cathode rotary pulley 8 moves to the right in the position shown in fig. 1; at the same time, the cathode rotary pulley 8 is disengaged from the belt 10, and therefore the cathode rotary pulley 8 does not rotate. The depth of the groove of the cathode rotating belt wheel 8 is 3 times of the thickness of the belt 10, so that the support belt 10 can not fall off from the groove of the cathode rotating belt wheel 8 when the cathode rotating belt wheel 8 moves to the right along the position shown in figure 1. Therefore, the apparatus can realize the rotation of the cathode 9 while ensuring the linear reciprocating movement of the cathode 9, or realize only the linear reciprocating movement of the cathode 9.
