Description

A coating controllable electroplating system

technical field

The invention relates to the field of electroplating technology, and further relates to a controllable electroplating system for a coating layer.

Background technique

In the traditional electroplating process, all anodes (anode titanium baskets or insoluble anodes) are placed on both sides of the electroplating tank, and the workpiece as the cathode passes between the anodes on both sides. When the electroplating current flows from the anode to the cathode through the electroplating solution, A coating is formed on the surface of the workpiece. However, in this form of electroplating process, since the scale of the entire electroplating activity exists between all workpieces and all anodes, the coating distribution and thickness of different workpieces will vary to some extent, that is, uneven.

On the other hand, workpieces of different sizes will have different plating areas, so different plating currents are required. Since the plating current flows from the positive output of the high-power plating rectifier to the anodes on both sides of the plating tank, and the current loops of all workpieces are Connected together and connected to the negative output of the high-power electroplating rectifier, so the electroplating current will flow to each workpiece in the electroplating tank, so the user can only control the total electroplating current of all the workpieces as a whole, but cannot independently control the received by each workpiece. electroplating current. Therefore, in the traditional continuous electroplating production line, the anode is generally set to output the calculated specific total electroplating current value, and then the cathode in the middle of the electroplating tank needs to be the same model and the specified number of workpieces are electroplating, so the flexibility of production very low.

Detailed ways

The core of the present invention is to provide a coating controllable electroplating system, which improves the consistency of the coating of the workpiece by setting independent workpiece combinations, and has higher electroplating production flexibility.

In order to make those skilled in the art better understand the technical solutions of the present invention, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The present invention provides a coating controllable electroplating system, including a supporting insulating plate 1, a bearing guide rail 2, a power supply sub-machine 3, a coating tank 4 and other structures, as shown in FIG. 1A and FIG. 2A, respectively, for the controllable coating provided by the present invention. Front view and side view of the electroplating system; Fig. 1B is a partial enlarged view of Fig. 1A, Fig. 2B is a partial enlarged view of Fig. 2A, A represents the anode, B represents the cathode; wherein the supporting insulating plate 1 is made of insulating material, It has an insulating effect and a supporting role, so the switch supporting the insulating plate 1 is not limited to a flat plate; on the supporting insulating plate 1, an anode clamp 11 for clamping the anode and a cathode clamp 12 for clamping the cathode workpiece are respectively arranged, The anode is relatively fixed to the supporting insulating plate 1 through the anode clamp 11 , and the cathode is relatively fixed to the supporting insulating plate 1 through the cathode clamp 12 .

The workpiece is used as the cathode. For the workpiece that needs to be coated on both sides, the anode clamps 11 should be arranged on both sides of the workpiece, each anode clamp 11 clamps an anode, each cathode clamp 12 clamps a cathode workpiece, and the cathode workpiece is located between the anodes on both sides. During the time, the plating layer can be quickly formed on both sides, but if the plating layer is only required to be formed on one side, only one side of the anode clamp can be provided.

The bearing guide rails 2 are arranged horizontally, and the length of the bearing guide rails 2 is much larger than the length of the supporting insulating plates 1 . The same carrier rail 2 supports. The carrying rail 2 can be made of insulating material.

The power supply sub-machine 3 is used to control the current and voltage required for electroplating the cathode workpiece. One or more power supply sub-machines 3 are arranged on each supporting insulating plate 1. The negative electrode of the output end of the machine 3, the anode and the cathode on each supporting insulating plate 1 form an independent workpiece combination, each independent workpiece combination forms a conductive circuit inside, and forms a plating layer on the cathode workpiece. It should be noted that each independent workpiece combination does not necessarily have only one power supply sub-machine 3. Two or more power supply sub-machines 3 can be set up to connect multiple anodes. The anodes on both sides of the workpiece can be independently controlled by a power supply sub-machine. Electroplating current; and when the electroplating area of the workpiece is large, even if there are multiple anodes on one side of the workpiece, multiple power supply sub-machines can also be set; and the workpiece has only one. The electrolytic solution is contained in the plating tank 4 , and the cathode and the anode are inserted into the plating tank 4 .

The coating controllable electroplating system of the present invention forms an independent workpiece combination with the relatively fixed anode and cathode of each supporting insulating plate 1, and each independent workpiece combination operates independently in the plating tank. Since the anode is no longer installed on both sides of the plating tank, it is fixed by the supporting insulating plate 1, and then clamped by the anode clamp 11 connected to the positive output end of the power supply sub-machine 3; the cathode workpiece is also fixed by the supporting insulating plate 1, and then used The cathode clamp 12 connected to the negative output end of the power supply sub-machine 3 is clamped; so during electroplating, the electroplating current only needs to flow from the anode to the cathode workpiece in the independent workpiece combination; the scale of this electric field is much smaller than the traditional common cathode and common anode structure. , so the interference changes will be very small, and the uniformity of the coating on the surface of the workpiece can be improved; in addition, because each cathode workpiece is plated through an independent combination of workpieces, the workpieces will not affect each other, as long as the control to each A combination of independent workpieces has consistent setting parameters, including plating current value, plating time, distance between workpiece and anode, shape and number of anodes, etc., so that all workpieces can have a more consistent coating after plating. .

Since each independent workpiece combination is independent, each workpiece combination can be configured with different workpieces, and then through radio control, the power supply sub-machines of different independent workpiece combinations are controlled to output matching electroplating currents, and electroplating is performed accurately; The components and antennas of radio communication are installed in the sub-machine, and the content of the single-chip microcomputer (MCU) is sent and received through the radio interface. This is different from the traditional continuous electroplating production line that needs to electroplate the same type and specified number of workpieces. This provides great flexibility for the production process and greatly increases the productivity of users.

Due to the design of independent workpiece combination, the distance between the anode and the cathode workpiece can be shortened, so the electroplating voltage can be reduced, the electroplating efficiency will be relatively high, and the effect of energy saving can be achieved.
