Abstract
A wire detection device and a wire detection method are provided. The wire detection device includes: a chamber body including a first side and a second side arranged opposite to each other; an electrode arranged at the second side of the chamber body; particles arranged within the chamber body; and a signal applying circuit configured to apply an electric signal to at least one wire to be tested arranged at the first side.
Claims16
A wire detection device, comprising:
- a chamber body comprising a first side and a second side arranged opposite to each other, wherein at least one wire to be tested are arranged at the first side;
- an electrode arranged at the second side of the chamber body;
- particles arranged within the chamber body;
- and
- a signal applying circuit configured to apply an electric signal to the at least one wire to be tested,
- wherein at least a portion of the second side of the chamber body is transparent, the electrode is a transparent electrode, the chamber body is filled with an electrophoresis solution, and the particles are electrophoresis particles, and
- wherein the electrophoresis solution is colored, and a color of the particles is different from a color of the electrophoresis solution;
- or, the electrophoresis solution is colorless, and the particles are colored electrophoresis particles.

A wire detection method, comprising:
- applying, by a signal applying circuit, an electric signal different from an electrode signal applied to an electrode to at least one wire to be tested, to generate an electric field within a chamber body between the at least one wire to be tested and the electrode, and drive particles within the chamber body by the electric field to move toward a first side of the chamber body;
- and
- detecting whether the at least one wire to be tested is defective based on an aggregation state of the particles at a first side of the chamber body,
- wherein the chamber body comprises the first side and a second side arranged opposite to the first side, the at least one wire to be tested are arranged at the second side, and the electrode is arranged at the first side,
- wherein at least a portion of the second side of the chamber body is transparent, the electrode is a transparent electrode, the chamber body is filled with an electrophoresis solution, and the particles are electrophoresis particles, and
- wherein the detecting whether the at least one wire to be tested is defective based on the aggregation state of the particles at a first side of the chamber body comprises:
- providing a predetermined pattern formed by the particles between the at least one wire to be tested in an intact state and the electrode;
- comparing a pattern formed by the electrophoresis particles with the predetermined pattern;
- and determining that at least one wire of the at least one wire to be tested is defective when the pattern is different from the predetermined pattern.
