They require that each product to be plated must have data to support the qualified rate, and each product to be plated must have data traceability in electroplating. However, the current detection device of the existing electroplating equipment is not sufficient to meet the above requirements. The current detection method of the existing electroplating equipment is a shunt detection method, that is, the original single rectifier outputs the detection current to the detection pinch point position, which is affected by the acid gas corrosion of the pinch point. The shunt detection current is affected by the resistance when passing through, which affects the current accuracy, resulting in a reduced electroplating effect and a reduced qualified rate of the products to be plated.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments: Example

[0034] Figure 1 The overall structural schematic diagram of an electroplating current online detection device provided by the first embodiment of the utility model is shown. The electroplating current online detection device is applied to an electroplating device, and the electroplating device includes a plurality of clamps, and a plurality of corresponding conductive sheets located below the plurality of clamps. During the electroplating process, the conductive sheets are electrically connected to the clamps, and a conductive slide rail is electrically connected to the clamps. The current online detection device includes:

[0035] A power supply device, wherein the positive pole of the power supply device is connected to the multiple conductive sheets through multiple current output interfaces, and the negative pole of the power supply device is connected to the conductive slide rail. The detection current of each current output interface is the same, and the detection current passing through each conductive sheet is also the same. The detection current passing through the multiple conductive sheets returns to the power supply device separately after passing through the conductive slide rail, so that the detection current is no longer evenly divided after passing through each conductive sheet, and the conductive sheet is no longer susceptible to corrosion from the pinch point acid gas when the detection current passes through the detection pinch point position, thereby causing the detection current to be affected by the extra resistance when passing through and reducing the accuracy of the detection current.

[0036] One specific implementation is that the current online detection device also includes a controller device, which is connected to the power supply device and is used to receive voltage data fed back by the power supply device. The power supply device sends the voltage data to the controller device in real time, so that the controller device can monitor the detection current of the electroplating equipment in real time;

[0037] The controller device includes a judgment module, which is used to compare the voltage data with a set value to determine whether there is abnormal data.

[0038] In one specific implementation manner, the controller device further includes an automatic alarm module, and the automatic alarm module is used to issue an alarm reminder when the judgment module determines that abnormal data exists.

[0039] In one specific implementation manner, the controller device further includes a data storage module, and the data storage module is used to store the voltage data so as to provide subsequent reference for operators and to perform maintenance according to the abnormal data.

[0040] In one specific implementation manner, the power supply device is a rectifier.

[0041] It should be noted that the rectifier is used as a power supply device in electrolysis, electroplating, and electrophoresis. It is mainly a machine that adjusts the current and voltage of the standard input power supply.

[0042] In one specific implementation manner, the voltage provided by the rectifier is 6V, and the output current of each current output interface is 5A, that is, the detection current passing through each conductive sheet is 5A.

[0043] In one specific implementation, the controller device is a programmable logic controller (PLC).

[0044] It should be noted that a programmable logic controller (PLC) is a digital computing electronic system designed specifically for use in industrial environments. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog input and output.

[0045] One specific implementation method is that the rectifier feeds back the voltage data to the PLC to display it in the DMS and compare it with the set value. When the fed-back voltage data exceeds a certain deviation range compared with the set value, the automatic alarm module in the PLC will automatically alarm to remind the operator and record the voltage data through RFID to the PLC for subsequent operator review and maintenance. Example

[0046] The utility model further provides an electroplating system, which includes an electroplating device and an electroplating current online detection device as provided in any specific implementation manner in Example 1 of the utility model.

[0047] In the electroplating system, the electroplating current online detection device independently provides detection current to the multiple conductive sheets through the rectifier, and the detection current passing through each conductive sheet can be accurately controlled, thereby avoiding the detection current being evenly distributed when passing through the multiple conductive sheets, resulting in the resistance change caused by acid gas corrosion on the surface of a single conductive sheet affecting the passage of the detection current. The electroplating current online detection device provides accurate control of the online detection current, solves the problem of conductive sheets not being resistant to corrosion in the prior art, enhances the electroplating effect, and improves the qualified rate of the products to be plated.

[0048] In one specific implementation manner, the conductive sheet is made of stainless steel.

[0049] In one specific implementation manner, the conductive rail is made of copper alloy.

[0050] Different from the prior art, the utility model provides an electroplating current online detection device and an electroplating system having the same, wherein the electroplating current online detection device is applied to an electroplating device, wherein the electroplating device comprises a plurality of fixtures, a plurality of corresponding conductive sheets located below the plurality of fixtures, and a conductive slide rail, wherein the conductive slide rail is electrically connected to the fixture, and wherein the current online detection device comprises:

[0051] A power supply device, wherein the positive pole of the power supply device is connected to the plurality of conductive sheets via a plurality of current output interfaces, and the negative pole of the power supply device is connected to the conductive slide rail.

[0052] It can be seen from the above technical solutions that the technical solution provided by the utility model has the following advantages:

[0053] The power supply device independently provides detection current to the multiple conductive sheets, and the detection current passing through each conductive sheet can be accurately controlled, thereby avoiding the detection current being evenly distributed when passing through the multiple conductive sheets, resulting in the resistance change caused by acid gas corrosion on the surface of a single conductive sheet affecting the passage of the detection current.
