Description

Technical Field

[0001] This invention relates to the field of sensor detection equipment technology, and in particular to an automatic detection device for the proximity characteristics of a position sensor. Background Technology

[0002] A position sensor is a device that converts the spatial position of an object into a measurable electrical signal. It is widely used to detect the presence, position, displacement, and angle of an object, and is a core sensing element in industrial automation and intelligent equipment. The production process of position sensors requires the detection of their proximity characteristics. Proximity characteristic detection refers to the sensor's perception and identification of a target object's approach, distance, or location. The core is determining whether the target is "approaching," its "approach distance," and its "approach direction," and converting the physical position information into an electrical signal output. Currently, most position sensor proximity characteristic detection is performed manually, which is difficult to operate and prone to significant detection errors during testing in a test chamber. Summary of the Invention

[0003] To address the problems mentioned in the background section, the present invention provides an automatic detection device for proximity characteristics of a position sensor.

[0004] This invention discloses the following technical solution: an automatic detection device for proximity characteristics of a position sensor, comprising a position sensor, a mounting base, a motor, a motor mount, a target, a displacement sensor, a sliding target mount, a power supply, a controller, and a signal acquisition system. The position sensor is mounted on the mounting base, the motor is mounted on the motor mount, and the target and displacement sensor are mounted on the sliding target mount. The motor pushes the sliding target mount to move back and forth, causing the target to approach and move away from the position sensor. The controller is used to receive the output signal of the position sensor, control the operation of the motor, and receive signal feedback from the signal acquisition system. The signal acquisition system is used to acquire the displacement signal of the displacement sensor, and the power supply provides power to the position sensor and the controller.

[0005] Furthermore, the mounting base is provided with mounting holes for the position sensor, facilitating the replacement of the position sensor. Furthermore, the mounting base is made of titanium alloy, which is a weakly magnetic metal with low electrical conductivity, thus eliminating the influence on the proximity feature detection of the position sensor.

[0006] Furthermore, the motor is a high-precision servo motor, which can effectively improve detection accuracy.

[0007] Furthermore, the movable target holder is made of titanium alloy, which can eliminate the influence on the proximity feature detection of the position sensor.

[0008] Beneficial effects: Compared with the prior art, the automatic detection device for proximity characteristics of position sensors of the present invention uses a motor to drive the target to move closer to or further away from the detection surface of the position sensor. The displacement sensor detects the distance signal between the target and the position sensor and transmits it to the signal acquisition system. The signal acquisition system records the distance signal and feeds it back to the controller. It automatically detects the distance signal of the position sensor in the approaching or moving away state, with high detection accuracy and simple operation. Attached Figure Description

[0009] Figure 1 This is a schematic diagram illustrating the working principle of the automatic detection device of the present invention. Detailed Implementation

[0010] like Figure 1 As shown, an automatic detection device for proximity characteristics of a position sensor includes a position sensor, a mounting base, a motor, a motor mount, a target, a displacement sensor, a sliding target mount, a power supply, a controller, and a signal acquisition system. The position sensor is mounted on the mounting base, the motor is mounted on the motor mount, and the target and displacement sensor are mounted on the sliding target mount. The motor pushes the sliding target mount to move back and forth, causing the target to approach and move away from the position sensor. The controller is used to receive the output signal of the position sensor, control the operation of the motor, and receive signal feedback from the signal acquisition system. The signal acquisition system is used to acquire the displacement signal of the displacement sensor, and the power supply provides power to the position sensor and the controller.

[0011] The mounting base is provided with mounting holes for the position sensor, which facilitates the replacement of the position sensor. The mounting base is made of titanium alloy, and the movable target base is made of titanium alloy. Titanium alloy is a weakly magnetic metal with low electrical conductivity, which can eliminate the influence of the position sensor on the proximity feature detection. The motor is a high-precision servo motor, which can effectively improve the detection accuracy.

[0012] In operation, pressing the "away" button on the controller reverses the motor, moving the target away from the position sensor. When the position sensor reaches the "away" state, its output signal changes. The controller, upon receiving the position sensor's output signal, immediately sends a stop signal to the motor. The motor stops, and the target ceases movement. The position sensor then sends the distance signal between the target's end face and the sensor's sensing surface to the signal acquisition system. The signal acquisition system records this distance signal and feeds it back to the controller. The controller then sends a forward rotation signal to the motor. As the motor rotates forward, the target approaches the position sensor. When the position sensor reaches the "approach" state, its output signal changes. The controller, upon receiving the position sensor's output signal, immediately sends a stop signal to the motor. The motor stops, and the target ceases movement. The displacement sensor then sends the approach distance signal between the target's end face and the sensor's sensing surface to the signal acquisition system. The signal acquisition system records this distance signal, thus completing the accurate and automatic detection of the position sensor's approach characteristics. This reduces the difficulty of detection operations and improves production efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
