The electromagnet to be tested is fixed on the carrier 20 and transported to the inspection station along the conveyor line. At the inspection station, the test conduction head module 8 is driven by the multi-axis transfer module to achieve electrical conduction with the electromagnet to be tested.

[0034] The first test module 5 includes a third motor 51, a third support plate 52 driven by the third motor 51 to move up and down, a pressure sensor 53 fixed on the third support plate 52, a first cylinder 54 fixed on the sensing end of the pressure sensor 53, a core clamp 55 driven by the first cylinder 54 to clamp the top of the core, and a shell pressing plate 56 fixed on the second support plate 4 and located below the core clamp 55 to press the shell, and a avoidance opening (not shown in the figure) for the core clamp 55 to extend through is provided on the shell pressing plate 56. The shell pressing plate 56 presses the electromagnet to prevent the position of the electromagnet from shaking or shifting during the detection process, thereby affecting the detection result.

[0035] In this embodiment, the electromagnet 40 to be tested is placed on the carrier 20.

The moving distance of the detection ejector pin 64 detected by the distance sensor 65 is the opening and closing stroke of the electromagnet, and is uploaded to the host computer system. The system determines whether the opening and closing stroke of the electromagnet meets the requirements, and the detection is completed.

The visual module 9 includes a fourth cylinder 91 fixed on the fourth support plate 62 and a visual camera 92 driven by the fourth cylinder 91 to move up and down.

[0041] The working process of an electromagnet multifunctional testing device 100 of the present embodiment is as follows: a carrier 40 carrying a plurality of electromagnets 40 to be tested moves to the bottom of the testing device along a conveyor line, an external manipulator clamps the electromagnet 40 and moves it to the position of a visual module 9, identifies the engraved information on the electromagnet 40, and uploads it to the system, and then puts it back into the carrier 40; a test conduction head module 8 moves onto the carrier 40, aligns it with the position of a wire head 401 corresponding to the electromagnet to be tested, a conduction probe 85 contacts the wire head 401, powers on the electromagnet, and uses an electromagnet comprehensive tester to complete the electromagnet test. The pull-in / release current and pull-in / release time are tested, and then the conductive probe 85 is disconnected; then the first test module 5 moves to the position directly above the electromagnet 40, and the core clamp 55 is used to clamp the top of the core, and the conductive probe 85 is turned on and powered on, and the pressure sensor 53 is used to detect the working force of the electromagnet, and then the conductive probe 85 is powered off; then the second test module 6 moves to the position directly above the electromagnet 40, and the conductive probe 85 is turned on and powered on, and the distance sensor 65 is used to detect the opening and closing stroke of the electromagnet, and then the conductive probe 85 is powered off to complete the multi-functional detection of the electromagnet.
