Description

Technical Field

[0001] This utility model relates to a position adjustment structure and position correction component for sensing and detection, belonging to the field of sensor position adjustment technology. Background Technology

[0002] Chinese Patent (Publication No.: CN119554532A) discloses a sensor position adjustment mechanism, including a left-right adjustment assembly. A lifting guide rod is mounted on the left-right adjustment assembly, and a sensor mounting base plate is mounted on the upper end of the lifting guide rod. A front-back adjustment assembly is mounted on the suspended end of the sensor mounting base plate. Sensor assemblies are mounted on both sides of the front-back adjustment assembly, and the sensor assemblies are arranged opposite each other, positioned above the manual loading position of the equipment. By pulling and pushing the adjusting screws, the left-right and front-back positions of the sensor assembly are first adjusted to their correct positions, and then the positions and relative spacing of the sensor assemblies are adjusted accordingly. This allows for stable, accurate, and rapid adjustment of the sensor positions, effectively preventing sensor displacement due to vibration, improving sensor detection accuracy, and meeting the requirements of high position detection conditions.

[0003] Although the above solution discloses a sensor position adjustment mechanism, it is difficult to correct for sensor position deviations at the millimeter level, which affects the sensor's detection accuracy.

[0004] The information disclosed in this background section is only for understanding the background of the present invention, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] To address the aforementioned problems or one of the aforementioned problems, the purpose of this utility model is to provide a position adjustment structure and position correction component for sensor detection. It consists of a first piece and a second piece fixed together at one end, with the other end spaced apart to form an adjustable gap structure. This allows for the correction of millimeter-level position errors, ensuring that the light emitted by the sensor is as perpendicular as possible to the detection end face, thereby further improving the detection accuracy of the ranging sensor.

[0006] In view of the above problems or one of the above problems, the second objective of this utility model is to provide a position correction component for sensor detection. By setting parallel correction components and alignment correction components, millimeter-level position correction can be easily achieved. Therefore, the horizontal angle and vertical position of the sensor can be easily fine-tuned so that the light emitted by the sensor is as aligned and perpendicular as possible with the detection end face, thereby further improving the detection accuracy of the sensor.

[0007] To achieve one of the above objectives, the first technical solution of this utility model is as follows:

[0008] A position adjustment structure for sensing and detection includes a first sheet and a second sheet;

[0009] One end of the first and second plates is fixed together, and the other end is spaced apart to form an adjustable gap structure for adjusting the position of the sensor.

[0010] Because conventional sensors are assembled with the emitting and detecting surfaces of the ranging sensor nearly parallel (i.e., the emitted light is nearly perpendicular to the detecting surface), the required error adjustment space is relatively small, typically only at the millimeter level. Conventional position adjustment mechanisms are insufficient for such positional correction. This invention, through continuous exploration and experimentation, incorporates a first and second piece fixed together at one end, with the other end spaced apart, forming an adjustable gap structure. This allows for millimeter-level positional error correction, ensuring the emitted light is as perpendicular as possible to the detecting surface, further improving the ranging sensor's detection accuracy.

[0011] As a preferred technical measure:

[0012] The first and second pieces are made of metal materials, with one end integrally formed. The structure is simple, practical, and easy to manufacture.

[0013] As a preferred technical measure:

[0014] The first and second plates have through holes at their fixed joint to increase the range of gap adjustment.

[0015] The first sheet and the second sheet are circular, square, or arc-shaped sheets.

[0016] As a preferred technical measure:

[0017] The through hole can be square, circular, or triangular.

[0018] As a preferred technical measure:

[0019] The first piece has several fixing holes, and the second piece has multiple receiving holes and / or adjustment holes.

[0020] As a preferred technical measure:

[0021] The vertical projections of the fixing hole and the receiving hole coincide. The diameter of the receiving hole is larger than that of the fixing hole, which facilitates the screw or bolt to pass through the receiving hole to fix the fixing hole and the first piece.

[0022] As a preferred technical measure:

[0023] The adjusting hole is connected to a limiting bolt. One end of the limiting bolt can be fixed to the first piece, and the other end is connected to the second piece through one or more nuts to adjust the gap between the second piece and the first piece.

[0024] To achieve one of the above objectives, the second technical solution of this utility model is as follows:

[0025] A position correction component includes a parallel correction element for adjusting the vertical position of a sensor and an alignment correction element for adjusting the longitudinal position of the sensor.

[0026] The parallel calibration component is one of the position adjustment structures used for sensing and detection described above;

[0027] The alignment correction component is provided with a fixing part for fixing to the moving part, a mounting part for assembling the ranging sensor, and a thin-walled part for connecting the fixing part and the mounting part.

[0028] The fixing part, thin-walled part and mounting part are integrally formed to create a fine-tuning structure.

[0029] The position correction component of this utility model includes a parallel correction component and an alignment correction component, which can easily achieve millimeter-level position correction. Therefore, it is very convenient to fine-tune the horizontal angle and vertical position of the sensor, so that the light emitted by the sensor is as close as possible to the detection end face and perpendicular to it, thereby further improving the detection accuracy of the sensor.

[0030] Furthermore, since the emitting end face and the detection end face of the ranging sensor are already almost parallel during conventional assembly (i.e., the light emitted by the sensor is almost perpendicular to the detection end face), the error space that needs to be adjusted is relatively small, generally only at the millimeter level. Conventional position adjustment mechanisms are difficult to meet the requirements for such position correction. Through continuous exploration and experimentation, this invention sets up a first piece and a second piece that are fixed together at one end, with the other end spaced apart to form an adjustable gap structure. This allows for millimeter-level position error correction, making the light emitted by the sensor as perpendicular to the detection end face as possible, thereby further improving the detection accuracy of the ranging sensor.

[0031] Similar to the adjustment scenario described above, after conventional assembly, the transmitting and detecting surfaces of the ranging sensor are nearly aligned, requiring only a small adjustment margin, typically at the millimeter level. Conventional alignment mechanisms are insufficient for such alignment corrections. Through continuous exploration and experimentation, this invention incorporates an integrally formed fixing part, a thin-walled part, and a mounting part. By utilizing the minute oscillation of the thin-walled part, millimeter-level alignment deviations can be corrected, thereby aligning the transmitting and detecting surfaces of the ranging sensor as closely as possible and further improving the detection accuracy of the ranging sensor.

[0032] As a preferred technical measure:

[0033] A moving part for driving the lateral movement of the sensor is assembled between the parallel correction part and the alignment correction part;

[0034] Adjacent mounting parts are provided with abutting components on the moving parts, which include positioning blocks for fixing to the moving parts and abutting bolts for passing through the positioning blocks;

[0035] The abutting bolt passes through the positioning block and abuts against the mounting part, allowing the mounting part to move a distance of millimeters with the cooperation of the thin-walled part.

[0036] And / or, the fixing part, the thin-walled part, and the mounting part are made of metal;

[0037] The fixing part is a block structure with at least one fixing through hole; the mounting part is a ring structure with a through hole for threading the ranging sensor cable.

[0038] As a preferred technical measure:

[0039] The moving part is a plate-shaped structure, a slide rail assembly, or a linear motor moving end, with its upper end fixedly connected to the alignment and correction part and its lower end assembled on the slide rail.

[0040] The slide rail is fixed to the upper end face of the parallel correction component, which can calibrate the levelness of the slide rail.

[0041] And / or, adjacent moving parts are equipped with travel sensors; the travel sensors are infrared detection sensors;

[0042] And / or, the sensor is a laser rangefinder or an infrared rangefinder.

[0043] Compared with existing technical solutions, this utility model has the following beneficial effects:

[0044] Through continuous exploration and experimentation, this utility model features a first and second piece fixed together at one end, with the other end spaced apart to form an adjustable gap structure. This allows for the correction of millimeter-level positional errors, ensuring that the light emitted by the sensor is as perpendicular as possible to the detection end face, thereby further improving the detection accuracy of the ranging sensor.

[0045] The position correction component of this utility model includes a parallel correction component and an alignment correction component, which can easily achieve millimeter-level position correction. Therefore, it is very convenient to fine-tune the horizontal angle and vertical position of the sensor, so that the light emitted by the sensor is as close as possible to the detection end face and perpendicular to it, thereby further improving the detection accuracy of the sensor.
