Identifying unit 62 can also be set the judgement that checks the state of insulation between object for.Now, identifying unit 62 is according to the resistance value between the magnitude of voltage information calculating inspection object that is stored in the current value information being detected between the inspection object in storage unit 63 and is applied in, and judges according to this result of calculation.Now, identifying unit 62 is for example stored in stipulated standard value information in storage unit 63, and above-mentioned result of calculation information and this reference value information are compared, and checks thus the judgement of the state of insulation between object.In addition, this result of determination is stored in storage unit 63.
It is more than the structure explanation of the insulation inspecting device 1 of the first embodiment involved in the present invention.
Action to the insulation inspecting device 1 of this first embodiment describes.
First, the information etc. that becomes the Wiring pattern P of the substrate CB that checks object is stored in storage unit 63.Then, substrate CB is disposed to inspection position and the configuration of the checkpoint on the Wiring pattern P being formed on the substrate CB contact CP of regulation.
At this, conventionally substrate CB is implemented the checking of Wiring pattern P.The checking of this Wiring pattern P refers to, calculates and is set in advance in the resistance value between the checkpoint on Wiring pattern P, and judge that according to this result of calculation whether the conducting state between this checkpoint is good.After the inspection that is implemented a plurality of Wiring patterns of predefined checking all finishes, substrate CB is implemented to insulation inspection.
The checking of all Wiring pattern P finishes the insulation inspection of rear beginning substrate CB.Now, selecting unit 61 selects as the Wiring pattern P that becomes the first inspection portion that checks object.If select unit 61, select the Wiring pattern P that becomes the first inspection portion that checks object, this is selected unit 61 and determines that to switch unit 7 the upstream side electric current of the Wiring pattern P that select as this inspection object provides terminal 81.And, determine simultaneously do not provide terminal 81 conductings to be connected with this upstream side electric current of this Wiring pattern P and with the contact CP of this Wiring pattern P conducting, and definite upstream side voltage detection terminal 91 that can be connected with this contact CP.And, from selecting unit 61 to switch unit 7 sending action signals, so that being provided, the on-off element SW1, the SW2 that provide terminal 81 and upstream side voltage detection terminal 91 to be made as connection status in this definite upstream side electric current be switched on.Now, select Wiring pattern P except the Wiring pattern P of the first inspection portion as the second inspection portion, determine the on-off element SW3 of these Wiring patterns P.And, from selecting unit 61 to switch unit 7 sending action signals, so that these on-off elements SW3 is switched on.

And, meanwhile, the contact CP contacting due to the Wiring pattern P2 with except this Wiring pattern P1 and even Wiring pattern P3 provides terminal 82 to be connection status with downstream electric current respectively, therefore selecting each downstream electric current provides the on-off element SW3 of terminal 82 and it is connected, and carries out action control (with reference to figure 2).In addition, in Fig. 2, the on-off element SW corresponding with the contact CP of checkpoint except above-mentioned Wiring pattern P2 and Wiring pattern P3 is all disconnected.
If shown in enforcement Fig. 2 select Wiring pattern P1 as the first inspection portion time insulation inspection, select next Wiring pattern P2 as the first inspection portion, and implement next insulation and check.Now, select Wiring pattern P2 as the first inspection portion, select Wiring pattern P1 and Wiring pattern P3 as the second inspection portion.
Now, in order to select Wiring pattern P2 as the first inspection portion, therefore, for example, be connected in conducting the on-off element SW1 that the contact CP of checkpoint of left end of Wiring pattern P2 of T font is corresponding and be switched on, thereby be connected with a terminal conducting of power supply unit 2.And, be connected in conducting the on-off element SW2 that the contact CP of checkpoint of right-hand member of Wiring pattern P2 of T font is corresponding and be switched on, thereby be connected with a terminal conducting of voltage detection unit 3.Now, power supply unit 2 is also connected by different contact CP conductings respectively with voltage detection unit 3.In addition, if meet this condition, be connected in conducting the on-off element SW that the contact CP of checkpoint of lower end of Wiring pattern P2 of T font is corresponding and also can be controlled so as to connection.
If select Wiring pattern P2 as the first inspection portion, select Wiring pattern P1 and Wiring pattern P3 as the second inspection portion.Now, on-off element SW3 is switched on, so that at least one of contact CP corresponding to the checkpoint of setting on Wiring pattern P1 and Wiring pattern P3 is connected in downstream electric current, provides terminal 82.In Fig. 3, the on-off element SW3 that is connected in the contact CP corresponding with the checkpoint of the upper end of Wiring pattern P1 is switched on, and the on-off element SW3 that is connected in the contact CP corresponding with the checkpoint of the left end of Wiring pattern P3 is switched on.
Set so successively the first inspection portion and the second inspection portion, it is that the first inspection portion finishes to check that all Wiring pattern P are selected.
If according to the present invention, when selecting the first inspection portion of form checking between object and the second inspection portion configuration switch element SW, implement insulation inspection.Now, between contact CP and Wiring pattern P, have contact resistance, but as the present invention, when terminal of power supply unit 2 and a connecting terminals of voltage detection unit 3 are connected to while becoming the Wiring pattern of the first inspection portion P, by different contact CP conductings, connect, therefore,, even provide electric power and contact resistance while changing at a terminal from power supply unit 2, can not exert an influence to voltage detection unit 3 yet.Therefore,, when wanting to observe the variation of voltage to detect spark in insulation checks, voltage detection unit 3 is not subject to the impact of the contact resistance causing to be provided and can be carried out exactly voltage determination by electric current.
