Description

Technical Field

[0001] This utility model relates to the field of magnetic sensor testing, and in particular to a rapid aging test device for magnetic sensor switches. Background Technology

[0002] Magnetic materials change their magnetic properties when exposed to external elements such as heat, light, pressure, and radiation. This allows for the creation of various reliable and highly sensitive sensors, which utilize magnetic materials as their sensing elements; hence, they are called magnetic sensors. With the increasing level of industrial electrical automation, magnetic sensors are finding wider and wider application in the precise control of cylinder stroke and movement.

[0003] After the magnetic sensor is manufactured, its lifespan and rapid aging conditions need to be tested. During testing, the magnetic sensor needs to be mounted on a cylinder, and the number of times the magnetic sensor opens and closes is tested by extending and retracting the cylinder. The above testing method is not only inefficient, but also inconvenient for counting and statistically analyzing the number of openings and closings, making the testing very inconvenient.

[0034] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0035] See Figures 1 to 8 This invention provides a rapid aging test device for magnetic sensor switches, comprising a housing 1, which can be placed on a desktop or tabletop, and is small in size and easy to operate. A detection platform 101 is provided at the upper end of the housing 1, and a detection coil 2 is installed on the detection platform 101. The detection coil 2 is located below the detection platform 101, and a detection cavity 201 with an open upper end is formed inside the detection coil 2. When the detection coil 2 is energized, a magnetic field is generated within the detection cavity 201 to facilitate detection. An insertion port 102 communicating with the detection cavity 201 is provided on the detection platform 101, through which the magnetic sensor can be inserted into the detection cavity 201. The detection platform 101 has multiple terminal blocks 3 installed on one side of the detection coil 2. A touch screen 4 is installed on the upper side of the detection platform 101. The touch screen 4 is used to adjust test parameters and display test data. For example, the number of tests and test voltage can be set through the touch screen 4. During the test, the touch screen 4 can display the number of tests of the sensor on each terminal block 3, which is convenient for observation. The touch screen 4 is existing technology and will not be described in detail in this embodiment.

[0036] During testing, one end of the magnetic sensor is wired to the terminal block 3, and the other end of the magnetic sensor is placed in the detection chamber 201 through the inlet 102. Then, the detection coil 2 is energized to generate a magnetic field that causes the magnetic sensor to open and close. The touch screen 4 can display the number of times the magnetic sensor has opened and closed.

[0037] In some embodiments, such as Figure 1 As shown, the detection platform 101 has multiple detection cylinders 5 installed on the side opposite to the terminal block 3. The detection cylinders 5 and the terminal block 3 are located on opposite sides of the detection coil 2. Magnetic sensors can be installed on the corresponding detection cylinders 5 to simulate real-world usage scenarios or for demonstration purposes. For example, the magnetic sensor can be placed in the mounting groove on the outer wall of the detection cylinder 5, and the presence of a detection signal can be observed by sliding the magnetic sensor. Alternatively, the magnetic sensor can be fixed in the mounting groove, and the cylinder can be driven to extend and retract to observe whether the magnetic sensor has a detection signal.

[0038] In some embodiments, such as Figure 1 and Figure 7 As shown, the terminal block 3 includes multiple two-wire terminal blocks 301 arranged at intervals along a straight line and multiple three-wire terminal blocks 302 arranged at intervals on one side of the two-wire terminal blocks 301. There are three two-wire terminal blocks 301 and two three-wire terminal blocks 302. By employing multiple terminal blocks with different structures, different types of magnetic sensors can be adapted, allowing for simultaneous testing of multiple magnetic sensors of different types, thus improving testing efficiency.

[0039] In some embodiments, such as Figure 1 As shown, the housing 1 has multiple test indicator lights 6 installed on the outer periphery of the touch screen 4. Each test indicator light 6 corresponds one-to-one with a number of terminal blocks 3. The test indicator lights 6 are configured to flash once when the magnetic sensor opens and closes once. There are five test indicator lights 6, matching the number of terminal blocks 3. When the magnetic sensor on a terminal block fails (it will not open or close in a magnetic field), the corresponding test indicator light 6 will not illuminate. This structure allows for a clear and intuitive display of the test status of the sensors on each terminal block, facilitating observation.

[0040] In some embodiments, such as Figure 1 and Figure 8 As shown, the detection cylinder 5 includes a first cylinder 501, a second cylinder 502, and a third cylinder 503 arranged at intervals along a straight line. The outer wall of the first cylinder 501 has a square first groove 504, the outer wall of the second cylinder 502 has a circular second groove 505, and the outer wall of the third cylinder 503 has a rectangular third groove 506. Compatible magnetic sensors can be installed within the first groove 504, the second groove 505, and the third cylinder 503. This structure, employing various grooves, can accommodate different types of magnetic sensors, offering a wide range of compatibility and flexible application.

[0041] In some embodiments, such as Figure 1 and Figure 3 As shown, a switch 7 and a buzzer 8 are installed on one side of the touch screen 4. The buzzer 8 can be turned on or off via the touch screen 4. The housing 1 is L-shaped, and a mounting platform 103 is provided on the housing 1 at an obtuse angle to the testing platform 101. The touch screen 4, test indicator light 6, switch 7 and buzzer 8 are all mounted on the mounting platform 103; this structure facilitates observation and operation of the touch screen 4.

[0042] In some embodiments, such as Figures 3 to 5As shown, the housing 1 has a mounting cavity 104 with an opening on one side. The detection coil 2 is placed inside the mounting cavity 104 and fixed to the lower end of the detection platform 101. A control component is installed inside the mounting cavity 104 and is connected to the detection coil 2. The control component includes a first power switch 9, a second power switch 10, a solid-state relay 11, and a PLC control board 12. The first power switch 9 is electrically connected to the PLC control board 12 to supply power. The second power switch 10, the solid-state relay 11, and the detection coil 2 are connected in series. The second power switch 10 supplies power to the detection coil 2. The PLC control board 12 is connected to the solid-state relay 11 and can send signals to the solid-state relay 11. The solid-state relay 11 can turn the detection coil 2 on or off. When the detection coil 2 is turned on, it generates a magnetic field, which then sends a signal to the magnetic sensor. The touch screen 4 and the terminal block 3 are electrically connected to the PLC control board 12.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, a cover plate 13 is installed on the housing 1. The cover plate 13 is used to cover the mounting cavity 104. The cover plate 13 can be detachably installed on the housing 1 by fastening screws. Support legs 14 are installed at the four corners of the bottom of the housing 1 for support.

[0045] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
