As shown in figure 1, it is the capacitance plate line detection apparatus 10 of an embodiment, including：Detector (not shown), first
Direction positions conductor, second direction positions conductor and at least some connectors 300, and in the present embodiment, the first direction is determined
Position conductor is conductive shaft 100, and second direction positioning conductor is conductive stylus 200.
The conductive shaft 100 has strip structure, and the conductive shaft 100 is used to electrically connect with the first end of detector,
Each connector 300 is respectively used to electrically connect with the second end of the detector, and the conductive stylus 200 is used for and the detection
The first end electrical connection of instrument, the conductive shaft 100 are in parallel with the conductive stylus 200.For example, the conductive shaft 100 and described
First end of the conductive stylus 200 respectively with the detector electrically connects, each connector 300 respectively with the detector second
End electrical connection.
Specifically, the detector is used for detection resistance, for example, the detector includes resistance monitor, for example, the detector
Including universal meter, for example, the detector includes detection IC (integrated circuit, integrated circuit), detection IC is also used
In control and the break-make of each connector 300.
For example, connector 300 is connection conductor, for FPC (the Flexible Printed with capacitance plate 400
Circuit, referred to hereinafter as flexible PCB, flexible PCB) stitch 411 connect, the stitch 411 of flexible PCB 410 namely
For the golden finger of flexible PCB 410, a stitch 411 of connection flexible PCB 410 per a connection piece 300, specifically, electric capacity
There are multiple circuits 420 on screen 400, each circuit 420 is connected with the stitch 411 on flexible PCB 410.So, detect
Instrument can be attached by each connector 300 with each circuit.
In the present embodiment, for ease of understanding, orthogonal X-direction and Y direction, Y direction are illustrated in Fig. 1
That is first direction, X-direction are second direction.Capacitance plate 400 has a square-section, and circuit is along a side of capacitance plate 400
Distribution, i.e., a side of each circuit each parallel to capacitance plate 400.As shown in figure 1, circuit is set along parallel to Y direction.
For example, the conductive shaft 100 is used to set along perpendicular to the direction of the side of capacitance plate 400 1, for example, the conductive shaft
100 are used to set along perpendicular to the direction of circuit 420, so, when conductive shaft 100 is connected to capacitance plate 400, conductive shaft 100
It can be connected with each circuit, for example, conductive shaft 100 is used to be movably set in institute along the direction parallel to the side of capacitance plate 400 1
State on capacitance plate 400, for example, conductive shaft 100 is used to be movably set in the capacitance plate 400 along the direction parallel to circuit,
So, when conductive shaft 100 translates, conductive shaft 100 specifically, in Fig. 1, is led with can be connected in each position of each circuit
Electric axis 100 is parallel to X-axis, and in other words, conductive shaft 100 is perpendicular to Y-axis, and conductive shaft 100 moves along Y direction, conductive shaft 100
For the position for the Y direction for positioning open circuit or short circuit.
For example, second direction positioning conductor includes conductive stylus 200, the conductive stylus 200 is used for the X for positioning open circuit or short circuit
The position of direction of principal axis, when conductive stylus 200 and connection, circuit forms loop by conductive stylus 200 and detector.
In the present embodiment, because conductive shaft 100 is perpendicular to each circuit, so, conductive shaft 100 is connected respectively with each circuit,

In enclosing, when conductive shaft 100 moves along Y direction, circuit 421 corresponding to the stitch 411a of capacitance plate 400 is in the Y-axis direction
Open circuit be present in a certain position, when position in Y direction corresponding to conductive shaft 100 moves to the open circuit, stitch 411a line
The resistance in the loop corresponding to road 421 is infinity, then detector can detect that circuit 421 is opened a way corresponding to the loop, and
Stitch 411a corresponding to loop is can detect that, detector is disconnected with other stitch in addition to stitch 411a, now, led
The stop motion of electric axis 100, then located the position in the Y direction of open circuit.
Then so that conductive stylus 200 is moved along conductive shaft 100 in X-direction, i.e., conductive stylus 200 is in fixed Y-axis position
Put along the direction parallel to X-axis and move, due to mutually isolated between each circuit, conductive stylus 200 and the connection of All other routes
Loop can't be formed, so, detector detects the resistance of conductive stylus 200 as infinity, until conductive stylus 200 move to
Circuit 421 connects corresponding to stitch 411a so that loop is formed between the circuit 421 corresponding with stitch 411a of conductive stylus 200, should
The resistance in loop is in normal range (NR), then the position where the conductive stylus 200 is the position opened a way in the X-axis direction, from
And it is accurately positioned open-circuit position.
It should be understood that the resistance of conductor is directly proportional to its length, that is to say, that conductor length is longer, and its resistance is got over
Greatly.When detecting short-circuit, incorporated by reference to Fig. 1 and Fig. 2, when conductive shaft 100 moves along Y direction towards the direction away from stitch,
With the increase of conductive shaft 100 and the length of connection, loop resistance value increase where circuit A and circuit B, conductive shaft 100 by
Circuit starts to slide close to one end of stitch 411, is directed away from one end of stitch 411.The resistance R tables of each section of circuit in figure
Show, and circuit 422 and the short circuit of circuit 423 on a certain position in Y-axis, circuit 422 and circuit 423 are short-circuit by short-circuit line 425,
Then after conductive shaft 100 slips over the position of the short-circuit line 425, resistance will no longer change, it is, the loop of conductive shaft 100 exists
The resistance of the position of short-circuit line 425 is maximum, therefore, can position the position of short circuit in the Y-axis direction, then so that conductive stylus
200 are moved along conductive shaft 100 in X-direction, i.e., conductive stylus 200 is transported in fixed Y-axis position along the direction parallel to X-axis
Dynamic, between two circuits, the resistance in the place loop of conductive stylus 200 is infinity, and when conductive stylus 200 slides into location of short circuit
When, the resistance in the place loop of conductive stylus 200 is in normal range (NR), then the position where the conductive stylus 200 is short circuit in X-axis side
Upward position, so as to be accurately positioned location of short circuit.
In above-described embodiment, the position of short circuit or open circuit in a first direction is positioned by conductive shaft 100, passes through conduction
The position of the positioning of pen 200 short circuit or open circuit in a second direction, it is achieved thereby that to the accurate of the position of short circuit or open circuit
Positioning, not only avoid the visual fatigue of testing staff, and it is low also to effectively improve detection efficiency, and improves Detection accuracy.
