Description

Technical Field

[0001] The invention belongs to the technical field of detection devices, and more specifically, particularly relates to an automatic loading and unloading detection platform for pulse electromagnetic valve detection. Background Art

[0002] The pulse solenoid valve inputs a pulse signal into the coil inside the solenoid valve body through a wire. The pulse valve is controlled by the output signal of the pulse controller. The pressure changes of the two air chambers before and after the valve cause the rubber diaphragm to bend and deform to open and close the pulse valve. The diameter of the rubber diaphragm determines the stroke size of the rubber diaphragm and the speed of opening and closing. The larger the diaphragm diameter, the larger the stroke and the better the blowing performance.

[0003] The positive pulse signal is input into the coil in the solenoid valve body through the wire, and the working magnetic flux generated by the coil causes the moving core to attract and open the valve. When the positive pulse signal input stops, the moving core is released, and the moving core returns to the initial state under the action of the spring force, closing the valve. In addition, there are self-holding pulse solenoid valves, which can maintain the position even after the positive pulse input stops or the power is cut off, and a negative pulse signal is required to reset. The working principle of the pulse solenoid valve is to use the pulse of the electrical appliance to convert it into mechanical pulsation, so that the powerful energy of the pulsating gas is converted into momentum, which is released in a short time to generate huge impulse. The interval of the pulse controlled by PLC should be determined according to the rated gas pressure recovery time.

[0004] At present, for the existing pulse solenoid valves, each solenoid valve is fully inspected for functionality before leaving the factory. The current pulse solenoid valve inspection method is mostly manual inspection. Workers place the pulse solenoid valve on the inspection platform for inspection, and manually judge whether the pulse solenoid valve is qualified. However, manual inspection not only consumes manpower, but also has low efficiency. Manual inspection is also prone to wrong judgment, and unqualified products may be mistaken for qualified products.

[0033] Two groups of T-shaped sliders 702 are fixedly connected to the bottom surface of the mounting plate 701, and the number of each group of T-shaped sliders 702 is two. The two groups of T-shaped sliders 702 are respectively adapted to the T-shaped slide grooves opened on the top surfaces of the two mounting frames 6, and the T-shaped sliders 702 and the T-shaped slide grooves have damping. A through hole 703 is opened on the surface of the mounting plate 701, and two cylinders 704 are fixedly connected to the top surface of the mounting plate 701. The cylinder 704 is electrically connected to the electronic control unit 9. The output ends of the two cylinders 704 are commonly fixedly connected to a connecting seat 705, and a test tube 706 is fixedly connected to the side of the connecting seat 705 away from the cylinder 704. A water inlet joint 708 is fixedly connected to the bottom of the test tube 706, and a sealing gasket 707 is fixedly connected to the end of the test tube 706 away from the connecting seat 705.

[0036] Working principle: The first step is to place the four solenoid valve bodies on the placement rack 709 (the loading and unloading of the solenoid valve bodies can be automatically performed by an external pneumatic tooling), so that the valve body outlet 802 faces the water tank 203, and the four second waterproof terminal heads 803 are plugged into the energized end of the solenoid valve body, and then the start button of the station control switch 202 is pressed to control the cylinder 704 to start.

[0039] In the fourth step, each test station 7 is automatically tested. If there are unqualified products during the test, the test is stopped and the alarm light 302 flashes to alarm. The corresponding red light on the display table 3 flashes and makes a sound. At the same time, the corresponding alarm position of the display 301 displays an alarm, and automatically switches to the next test station 7 for testing.
