Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a magnetic detection device for an inductive sensor. Background Art

[0002] An inductive sensor is a device that uses the electric field of current to detect objects. It is often used in many fields such as detection switches, speed switches, and speed detection. It has many advantages such as non-contact, high efficiency, and high sensitivity. However, it is extremely susceptible to interference from external magnetic fields, resulting in erroneous signals. Therefore, some inductive sensors have the ability to protect against external magnetic fields. After their production is completed, such inductive sensors need to be subjected to magnetic testing to determine whether their protection capabilities are qualified. However, existing equipment can only perform a single number of tests, which is very inefficient. Utility Model Content

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a magnetic detection device for an inductive sensor, which has the following beneficial effects:

[0016] 1. By setting up a turntable and a magnetic source, during detection, the inductive sensor is inserted into the detection simulator, and then the turntable moves the detection simulator and the inductive sensor to the subsequent workstation. When the inductive sensor moves to the position of the magnetic source, the magnetic field of the magnetic source will interfere with the electric field of the inductive sensor. When the protection of the inductive sensor is qualified, the detection simulator has no signal. When the protection of the inductive sensor is unqualified, the inductive sensor is triggered by the magnetic field, the detection simulator sends a signal, and is pushed out by the unloaded parts at the subsequent workstation.

[0017] 2. By setting a movable roller and a fixed roller, after the detection simulator sends a signal, the movable roller is triggered and moves forward.

[0025] A material removal component 3 is provided on the side of the detection simulator 4, and the material removal component 3 is used to push the inductive sensor out of the detection simulator 4;

[0026] In the present utility model, a turntable 2 and a magnetic source 9 are provided. By utilizing the turntable 2 and a plurality of detection simulators 4, the continuous and continuous loading detection work of the inductive sensor can be realized, and the magnetic source 9 can be used to automatically detect the inductive sensor, thereby reducing the manual labor intensity. In addition, it should be further explained that the material return component 3 can be used to realize the automatic material return work of the inductive sensor, thereby further reducing the manual labor intensity.

[0027] A movable roller 10 is provided on the frame 5 at a position behind the fixed frame 8, and the movable roller 10 is electrically connected to the detection simulator 4. The movable roller 10 includes a roller and a telescopic rod, and the telescopic rod is used to drive the roller to move horizontally;

[0028] By setting up a movable roller 10, the movable roller 10 can extend forward after the detection simulator 4 is triggered, trigger the material return component 3, and use the material return component 3 to push out the problematic inductive sensor, thereby achieving the purpose of automatic material return and avoiding mixing of problematic inductive sensors with qualified inductive sensors.

[0029] A fixed roller 11 is provided on the side of the frame 5 at the rear position of the movable roller 10. The fixed roller 11 includes a roller and a fixing frame 8. The fixing frame 8 is used to support the roller.

[0030] By setting the fixed roller 11, the fixed roller 11 can trigger the material-removing component 3 after the detection is completed, and use the material-removing component 3 to push out the inductive sensor, thereby achieving the purpose of automatic unloading after the detection is completed, further reducing the labor intensity of manual labor.

[0031] The material stripping component 3 includes a slide rod 301 and a push plate 303. The slide rod 301 is movably connected to the detection simulator 4 through a sliding sleeve. The push plate 303 is connected to the front end of the slide rod 301 and is sleeved on the external end of the detection template machine.

[0032] By setting the slide rod 301 and the push plate 303, the slide rod 301 utilizes the sliding connection with the sleeve to achieve the purpose of its own horizontal movement, and can drive the push plate 303 to move during the horizontal movement, thereby achieving the purpose of using the push plate 303 to push the inductive sensor out of the detection simulator 4.

[0033] A spring 302 is provided on the side of the slide bar 301, and the spring 302 applies a pulling force to the slide bar 301 to move backward. A slanted plate 304 is provided at the tail end of the slide bar 301, and the slanted plate 304 is in contact with the movable roller 10 or the fixed roller 11;

[0034] By setting the spring 302 and the inclined plate 304, the spring 302 supports and limits the slide bar 301. On the one hand, it can stabilize the slide bar 301 to prevent it from moving at will. On the other hand, it can promptly drive the slide bar 301 to reset after being squeezed and displaced. The inclined plate 304 will contact the movable roller 10 or the fixed roller 11, converting the squeezing force into external horizontal movement, thereby achieving the purpose of driving the slide bar 301 to move horizontally.

The first collection box 6 is used to collect inductive sensors that have detected problems. A second collection box 7 is provided on the side of the base 1 at the position corresponding to the fixed roller 11. The second collection box 7 is used to collect inductive sensors that have completed the detection process.

[0036] By setting up a first collection box 6 and a second collection box 7, after the movable roller 10 triggers the material return component 3, the pushed out inductive sensor will fall into the first collection box 6, otherwise the subsequent inductive sensor will fall into the second collection box 7 under the push of the material return component 3 triggered by the fixed roller 11, thereby achieving the purpose of automatic collection and classification.

[0037] Working principle:

[0038] During the test, the inductive sensor is inserted into the test simulator 4, and the turntable 2 drives the test simulator 4 and the inductive sensor to rotate to the subsequent station. When the magnetic source 9 is in position during the movement, the magnetic source 9 will interfere with the electric field of the inductive sensor. If the protection of the inductive sensor is qualified, the test simulator 4 will not respond. If the protection of the inductive sensor is unqualified, the magnetic field of the magnetic source 9 will interfere with and trigger the inductive sensor, causing the test simulator 4 to send a signal.

[0039] After the detection simulator 4 sends a signal, it triggers the movable roller 10 after a delay, causing the movable roller 10 to move forward, triggering the material return component 3 of the detection simulator 4 carrying the problematic inductive sensor, and pushing the inductive sensor into the first collection box 6. The simulation detection machine carrying the qualified inductive sensor will continue to rotate backward, trigger the material return component 3 after moving to the fixed roller 11, and push the inductive sensor to the second collection box 7.

[0040] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
