In order to more clearly understand the technical solution of the present invention, the following describes the operation process of the third embodiment of the present invention. By the utility model, the automatic detection of the electric performance of the workpiece on the production line can be realized.

Firstly, when a workpiece is on line (namely, when the workpiece is positioned on a production line body), a plug is inserted into the socket 21 of the upper plate 2 in the tooling plate;

then, when the tooling plate including the upper plate 2 and the lower plate 5 on the assembly line body moves to the detection position below the detection head 1, the tooling plate is lifted up under the action of the supporting plate assembly 10 and the supporting plate driving cylinder, so that the tooling plate can be separated from the running assembly line body 100;

then, the power supply body 6 moves upward under the pushing of the power supply driving cylinder 9, and contacts with the power receiving body 51, so that the power supply mechanism acts to supply power to the socket 21 on the tool plate, and further electrify the workpiece;

and then, the detection head 1 moves downwards under the driving of the detection head driving cylinder, and the detection copper needle 14 in the detection head 1 is contacted with the upper surface of the workpiece, so that the connection between the workpiece and the tester is realized, and the tester starts to detect the electrical property of the workpiece.

For the utility model, when the workpiece is a disc motor, the detection mode is as follows: disc motor inserts the row of inserting with the plug after getting on the standard grade, and the row of inserting links to each other through "coil test socket" port of feed mechanism with motor stator comprehensive tester, reachs and detects the position after, detects head 1 and contacts with disc motor's motor casing, links to each other because of detecting head 1 and passing through screw 140 and motor stator comprehensive tester "high voltage output end", so disc motor's motor casing links to each other with the tester promptly, alright begin to carry out the detection of electric property. In addition, when detecting, need to connect the motor casing of disk motor comprehensive test appearance main objective: and detecting the insulation resistance of the coil winding of the motor to the motor shell, wherein high voltage is loaded on two sides of the motor shell and the coil winding of the motor.

After detection, the motor stator comprehensive tester displays 'GO', the detection is qualified, and the tester displays 'NG', the detection is unqualified.

It should be noted that two preconditions are required for detecting the electrical performance of a workpiece such as a motor, one precondition is that a power plug of the workpiece (such as the motor) needs to be connected with a port of a coil test socket of a tester; the other is that the shell of the workpiece (such as a motor) needs to be connected with a 'high-voltage output end' port of the tester, and the port connected with the detection copper needle 14 is the port.

The two ports to be connected are specified by the tester, but the design of the connection mode of the workpiece and the tester is peculiar to the patent, and in specific detection, the detection method and principle in the tester are functions of the tester.

Then, after the detection is finished, the power supply body 6 in the power supply mechanism retracts, the detection head 1 retracts, and the supporting plate assembly 10 drives the tooling plate comprising the upper plate 2 and the lower plate 5 to fall down.
