Abstract
The utility model provides a current density meter for electroplating, and relates to a detecting instrument for measuring the density of currents in electroplating solution in an electroplating bath. The current density meter solves the problems that the existing device for measuring the density of the currents in the electroplating solution is complex in structure, high in cost or low in accuracy, and comprises an ammeter, an insulating bar and a conducting piece, wherein the conducting piece is arranged at the bottom end of the insulating bar; at least one surface of the conducting piece is exposed outside the insulating bar which is internally provided with a metal wire; and the ammeter is connected with the conducting piece by the metal wire. In the current density meter, the conducting piece with unit area is arranged at the bottom end of the insulating bar, so that in measurement, no matter how the depth of the insulating bar inserted into the electroplating solution is, the measured conducting areas are same, therefore, the error is small, the measurement accuracy is high, the structure is simple, the cost is low, and the practicability is achieved.
Description
Technical field
The utility model relates to the measuring instrument of the current density in the electroplate liquid that is used for measuring electroplating bath in the electroplating technology.
Background technology
At present, in electroplating technology, the current density mode of measuring in the electroplate liquid in the electroplating bath mainly contains two kinds: the one, utilize electromagnetic induction principle, and measure by the mode of hall device; The 2nd, measure by the mode that cathode bar directly inserts in the electroplate liquid, existing first kind of mode measured used device and had complex structure, cost height, second kind of used device of metering system, measuring accuracy is poor, the depth of inserting in the electroplate liquid with device changes, the surface of contact respective change of device and electroplate liquid influences measurement result.
Summary of the invention
In sum, goal of the invention of the present utility model is current density equipment therefor complex structure, cost height or the low problem of precision measured in the electroplate liquid at existing, and proposes a kind of plating current density table.
For realizing that the technical scheme that goal of the invention of the present utility model adopts is: electroplate and use the current density table, it is characterized in that: comprise reometer, insulation rod and conducting strip, described conducting strip is located at the insulation rod bottom, conducting strip has at least one side to be exposed to outside the insulation rod, be provided with plain conductor in the described insulation rod, described reometer is connected with conducting strip by plain conductor.
As being to the further improved technical scheme of the utility model:
Described reometer is fixed at the insulation rod top.
Described insulation rod is provided with Removable hook.
Described Removable hook and insulation rod are for being threaded.
Described Removable hook and insulation rod also can connect for active card.
The beneficial effects of the utility model are: the conducting strip of unit area is located at the insulation rod bottom, during measurement, inserts the depth in the electric liquid regardless of insulation rod, and it is all identical to measure conductive area, and error is little, the measuring accuracy height, and simple in structure, cost is low, practicality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment structure of the present utility model is further described:
Shown in Fig. 1, the utility model comprises reometer 1, insulation rod 2 and conducting strip 3, and conducting strip 3 is located at the bottom of insulation rod 2, and reometer 1 is fixed in the top of insulation rod 2.In measuring electroplate liquid during current density, conducting strip 3 is used for directly contacting with electroplate liquid, conducting strip 3 preferably will wherein simultaneously be embedded in the insulation rod 2 bottom sidewalls in the mode that embeds, be provided with plain conductor in the insulation rod 2, insulation rod 2 directly seals plain conductor or directly fusion is in the outside of plain conductor, as long as not contacting with electroplate liquid, the assurance plain conductor all can not, plain conductor one end connects one of them leads ends that conducting strip 3 other ends connect reometer 1, another leads ends use of reometer 1 is connected with the negative electrode in the electroplating technology, makes the utility model be equivalent to a cathode bar.Place in the electroplating bath when the utility model is measured for convenience, but be connected to the Removable hook 21 of a up-down adjustment in the first half sidewall sheath of insulation rod 2, Removable hook 21 can be to be threaded with 2 of insulation rods, also can pass through the buckle clamping, directly is hung on the cell wall of electroplating bath during use.
