But this detection occurs when plating has started, and the like, and even if a machine is stopped, it has caused rejection of the product.

There is therefore a need to develop a new device for detecting the conductivity of a target in a fly to avoid the above problems.

Detailed Description

The present utility model will be described in further detail with reference to specific examples.

Examples:

as shown in fig. 1 and 2, the on-line conductivity detection device for electroplating targets of the present utility model comprises targets 1 moving along the direction of a production line, wherein the lower part of each target 1 is provided with a plurality of upper clamps 11 for clamping a plate 2 to be electroplated, one side of the inlet of the production line is provided with polar plates 3 for conducting electricity with all the upper clamps 11, the lower part of the inlet of the production line is also provided with lower clamps 4 corresponding to the positions of the upper clamps 11 one by one, each lower clamp 4 is connected with one test wire 5, each test wire 5 is provided with an ammeter 6, the polar plates 3 are connected with a first electrode 71 of a direct current power supply 7, all the test wires 5 are connected with a second electrode 72 of the direct current power supply 7, and all the lower clamps 4 are used for clamping the lower edges of the plate 2 to be electroplated to form a plurality of parallel circuits. Because the upper clamps 11, the plate material 2 to be plated and the plating solution form a uniform conductive layer during plating, the current on each upper clamp 11 is substantially uniform in the operating state. The current will travel the nearest way from the upper clamp 11 to the lower clamp 4 closest thereto, so that the plate 2 to be plated itself corresponds to a number of resistors in parallel, and if the upper clamps 11 are each normal, the readings on the ammeter 6 will also be averaged. The utility model can clamp the plate 2 to be electroplated by using the lower clamp 4 to form a plurality of loops, if the upper clamp 11 has a circuit breaking problem, the current value on the corresponding ammeter is abnormal, and then a worker is reminded to overhaul the upper clamp, so that the problem is not found in the manufacturing process, and the scrapped plate is prevented from being increased.

As shown in fig. 1, the polar plate 3 is an elongated structure extending along the production line, and the length of the polar plate 3 is not less than 30mm. The flying target 1 is provided with a section of conducting wire which is communicated with the upper clamp 5 and can form conductive connection with the polar plate 3, and when the flying target 1 reaches the position of the polar plate 3, even if the position has a little deviation, the conduction can be ensured.

As shown in fig. 1, one side of the lower clamp 4 is provided with a clamp opening mechanism 8, and the clamp opening mechanism 8 includes a driving member 81 and a push block 82 driven by the driving member 81, the push block 82 being used to simultaneously open all the lower clamps 4 to clamp the lower edge of the plate material 8 to be plated. Before the target 1 carries the plate 8 to be electroplated into the detection position, the lower clamp 4 needs to be opened firstly, wherein the push block 82 is adopted to open the lower clamp 4, and after the plate 8 to be electroplated is in place, the push block 82 releases the lower clamp 4, so that the lower clamp 4 can clamp the plate 8 to be electroplated; after the test is finished, if the conductivity detection result is not wrong, the pushing block 82 pushes and opens the lower clamp 4 again, so that the plate 8 to be electroplated enters the electroplating station.

As shown in fig. 2, all the ampere meters 6 are arranged in an electric cabinet 6, the direct current power supply 7 is a rectifier connected with an alternating current bus, and the rectifier is also arranged in the electric cabinet 6. The conductivity measurement should be performed using a steady direct current so that a steady current reading is obtained. The rectifier has the function of converting alternating current into direct current, so that the rectifier can be used after being connected with a conventional alternating current bus.

As shown in fig. 2, a controller 63 for collecting signals of the ammeter 61 is further arranged in the electric cabinet 6, and the controller 63 is further connected with an alarm 64 for alarming current abnormality. If the conductivity detection results find that there is a problem, it means that at least one upper clamp 11 has a problem of breaking, and at this time, the controller 63 can control the alarm 64 to alarm in sound, so that the worker can stop the process in time, and the process is continued after the problem is eliminated.

What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
