Description

Technical Field

[0001] This utility model relates to the technical field of magnetic switches, and in particular to a device for testing the full-load life cycles of a magnetic switch. Background Technology

[0002] A magnetic switch, also known as a magnetically controlled switch or magnetic force switch, is a switching device that uses changes in a magnetic field to control the on / off state of a circuit. The working principle of a magnetic switch is based on the interaction between a magnet and a magnetic sensing element. When a magnet approaches the magnetic sensing element, the magnetic field within the element changes, triggering the switch. Specifically, the magnetic sensing element inside the switch (such as a Hall effect sensor, reed switch, or magnetic diode) senses the change in the magnetic field and generates a corresponding electrical signal. This signal controls the opening or closing of the switch contacts, thus controlling the circuit's on / off state. Currently, in industrial robots, conveyor belts, automatic doors, and other equipment, magnetic switches are used to detect the position and status of mechanical parts, enabling automatic start / stop, position detection, and safety protection functions. In household appliances such as refrigerators, washing machines, and air conditioners, magnetic switches are used to detect the open / closed state of doors and control the start and stop of compressors. In automotive electronic systems such as engine control, airbags, and anti-theft systems, magnetic switches are used to detect wheel speed and door open / closed states, achieving corresponding control functions. In addition, magnetic switches are also commonly used in access control systems, smart homes, and other fields to detect the open or closed status of doors and windows, enabling security protection and automatic control functions. Currently, during the production process of magnetic switches, it is necessary to test their lifespan, but the current testing equipment has low testing efficiency. Utility Model Content

[0022] This utility model discloses a device for testing the full-load lifespan of a magnetic switch, such as... Figs. 1-3As shown, the device includes a body 1, on which multiple mounting bases 12 are fixedly installed. The mounting bases 12 are arranged in a circular pattern. In this embodiment, the number of mounting bases 12 is preferably ten, but not limited to ten. Each mounting base 12 has a connector slot, on which a magnetic switch 2 is inserted. Additionally, the body 1 is equipped with a power supply, which is connected to 220V AC and outputs 24V DC. The power supply is connected to a power switch 17, which powers the device when pressed by a tester. The power supply is electrically connected to the multiple magnetic switches 2, with one end of each magnetic switch 2 connected to the positive terminal of the power supply and the other end connected to the negative terminal. Each magnetic switch 2 is electrically connected to a load module 21, which is connected in series. In this embodiment, the load module 21 is preferably a 10W, 10Ω resistor. In addition, each magnetic switch 2 is electrically connected to a test counter 14, which is fixedly mounted on the body 1. The magnetic switch 2 and the test counter 14 are connected in series, and the test counter 14 and the load module 21 are connected in parallel. Furthermore, the body 1 has multiple sockets 13, all of which are electrically connected to a power supply. Each magnetic switch 2 has a wire 22, one end of which is electrically connected to the magnetic switch 2, and the other end of which has a plug. The plug is electrically engaged with the socket 13. After testing a set of magnetic switches 2, the tester removes the magnetic switch 2 from the mounting base 12 and unplugs the plug from the socket 13, allowing the next set of magnetic switches 2 to be installed for testing.

[0023] Additionally, a rotating rod 11 is provided on the body 1, located between multiple magnetic switches 2. A driving component for rotating the rotating rod 11 is provided on the body 1. Specifically, the driving component includes a drive motor fixedly mounted on the body 1, the drive motor being arranged along the axial direction of the multiple magnetic switches 2. The rotating rod 11 is perpendicular to the drive motor, one end of the rotating rod 11 is fixedly connected to the output shaft of the drive motor, and the rotating rod 11 is arranged radially along the multiple magnetic switches 2. A magnet is provided on the rotating rod 11. When the rotating rod 11 approaches one of the magnetic switches 2, the magnetic switch 2 senses the magnet, thereby causing the magnetic switch to turn. When switch 2 is closed, as the drive motor rotates the rotating rod 11, the magnet on the rotating rod 11 rotates among multiple magnetic switches 2. This causes the magnet to circulate back and forth among the magnetic switches 2. As the rotating rod 11 rotates, the magnet moves closer to the magnetic switch 2, closing it. Then, as the rotating rod 11 continues to rotate, the magnet moves away from the magnetic switch 2, opening it. The rotating rod 11 then moves closer to the next magnetic switch 2, and so on, continuously testing the opening and closing of multiple magnetic switches 2. Each time a magnetic switch 2 is on, it is for 2 seconds, and one rotation of the rotating rod 11 takes approximately 20 seconds. The test counter 14 records the number of times the magnetic switches 2 have been opened and closed, allowing the tester to know the number of tests conducted.

[0024] In addition, the drive motor is electrically connected to a controller, which is preferably a PCB circuit board. The controller is electrically connected to a power supply and has a motor speed control knob 15. When the tester wants to adjust the speed of the drive motor, rotating the motor speed control knob will adjust the speed of the drive motor. In addition, a photoelectric sensor 16 is provided on the body 1. The photoelectric sensor 16 is electrically connected to a rotation counter 18. The sensing end of the photoelectric sensor 16 is located on the movement path of the rotating rod 11. When the rotating rod 11 rotates one revolution and reaches the photoelectric sensor 16, the photoelectric sensor 16 senses the rotating rod 11 and sends the data to the rotation counter 18. The rotation counter 18 records the number of revolutions of the rotating rod 11 for the tester to know.

[0025] In addition, a light bulb 3 is electrically connected between the power supply and multiple magnetic switches 2. The light bulb 3 is connected in series with the magnetic switches 2. When one magnetic switch 2 is closed, all light bulbs 3 light up. If a light bulb 3 remains constantly lit or does not light up, it indicates that a magnetic switch 2 is damaged, thus confirming the lifespan of the magnetic switch 2 at maximum power. The light bulb 3 can be replaced according to the power requirements. Furthermore, a voltmeter 4 is electrically connected to the power supply, measuring the output voltage. An ammeter 5 is connected in series with the power supply; whenever a magnetic switch 2 is closed, the ammeter 5 measures the output current. Based on the data from the voltmeter 4 and ammeter 5, the tester can easily determine the power of the entire circuit.

[0026] The implementation principle of the magnetic switch full-load life test device of this utility model is as follows: The tester installs a set of ten magnetic switches 2 on the body 1. During the test, the drive motor drives the rotating rod 11 to rotate. The magnet on the rotating rod 11 causes multiple magnetic switches 2 to close and open in sequence. The test counter 14 records the number of times the magnetic switches 2 close and open. When the magnetic switch 2 is damaged, the tester judges whether the life of the magnetic switch 2 meets the requirements based on the data on the test counter 14. The whole test process is convenient and quick, the test speed is fast, and it can test the life of multiple magnetic switches 2 at maximum power at one time. The test efficiency is high and the operation is stable. It has been tested for 1 million times so far.
