Example Embodiment

[0020] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0021] In this disclosure, in the absence of a statement to the contrary, the use of orientation words such as "up, down" is based on figure 1 defined, specifically, figure 1 The left side of the middle drawing may refer to the upper side, the right side may refer to the lower side, and the up and down directions correspond to the vertical direction. The terms "first, second" are used to distinguish one element from another, without sequence or importance.

[0022] According to a specific embodiment of the present disclosure, a sensor calibration device is provided, referring to figure 1 As shown in , the calibration device includes a calibration plate 1, ...

Abstract

The invention relates to a calibration device for a sensor, the calibration device comprises a calibration plate (1), a slide rail (21), a translation driving mechanism, a first mounting bracket (4) and a position sensor (5), the calibration plate (1) is slidably connected to the slide rail (21) through a slide block (22), the translation driving mechanism is used for driving the calibration plate (1) to slide along the slide rail (21), the first mounting bracket (4) is arranged in the extension direction of the sliding rail (21) and is provided with a mounting seat (7) for mounting a sensor (10) to be calibrated, and the position sensor (5) is used for detecting the position coordinates of the sliding block (22) so as to calibrate the sensor (10) to be calibrated. The calibration device can improve the calibration efficiency and ensure the calibration precision while achieving the dynamic calibration of the sensor.

Description

technical field [0001] The present disclosure relates to the technical field of sensors, and in particular, to a sensor calibration device. Background technique [0002] In the related art, when the sensor is calibrated, the sensor and the calibration plate are generally fixed on two objects respectively, and the distance between the sensor and the calibration plate is measured by measuring tools such as a ruler, and then the sensor is calibrated according to the measured distance, or fixed. For several points with different distances, after determining the distance between the point and the calibration plate, the calibration is performed by placing the sensor on different points. However, the current calibration methods have low calibration accuracy, and the calibration process is cumbersome, resulting in low calibration efficiency. Contents of the invention [0003] The purpose of the present disclosure is to provide a sensor calibration device, which can improve the ca...
