Description

Object assembly position detection device

technical field

The utility model relates to an object assembly position detection device, which is used to solve the problem of judging whether the positions of two objects are consistent during assembly.

Background technique

When installing two objects that slide relative to each other, when judging whether the installation is in place, the relative position information of the two objects becomes a very important criterion for judging. In the prior art, a magnetic position sensor has been designed. The method is to install a Hall sensor on one object and a magnet on another object. When the positions of the two objects change, the amount of magnetic field received by the Hall sensor will The relative position of two objects can be calculated by measuring the current value or voltage value of the Hall sensor. The disadvantage of this method is that it has high requirements on the working environment and is easily affected by noise or other external disturbances, resulting in unstable and reliable measurement values.

Utility model content

The purpose of the utility model is to provide an object assembly position detection device aiming at the shortcomings of the prior art.

The utility model is achieved through the following technical solutions:

The object to be detected at the lower end is installed in the object relative position sensing detection part, and the object to be detected at the upper end moves to the right. When the center line of the non-contact capacitive liquid level sensor reaches the left boundary of the sealed water box, the non-contact capacitive liquid level sensor The indicator light is on, indicating that the installation position matches.

The structure of the utility model includes: object relative position sensing detection part and single-chip microcomputer control part, object relative position sensing detection part is composed of upper end detected object, non-contact capacitive liquid level sensor, non-contact capacitive liquid level sensor and single-chip microcomputer It is composed of connecting lines, objects to be detected at the lower end, and a sealed water box.

A non-contact capacitive liquid level sensor is installed on the surface of the object to be detected at the upper end, a sealed water box is installed on the lower surface of the object to be detected at the lower end, and the non-contact capacitive sensor is connected with the control part of the single-chip microcomputer through a connecting line.

The beneficial effects of the utility model are:

A non-contact capacitive liquid level sensor is used as the acquisition of the front position signal. Since the sensor adopts a pure electronic circuit structure, non-mechanical working mode, stable performance, long life, high stability, high sensitivity, good anti-interference, and is not affected by the outside world. Electromagnetic interference is suitable for use in complex environments, so the device can overcome the shortcomings of the prior art that are susceptible to external interference, and provide better stability and reliability for the detection of the relative position of objects.

Since the installation positions of the non-contact capacitive liquid level sensor and the sealing water box in the device can be adjusted arbitrarily, and the size of the sealing water box can also be adjusted, the device has wide applicability when detecting the relative positions of different objects .

The device has a simple structure and is easy to use.
