Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to an angle calibration device for a posture sensor. Background Art

[0002] Attitude sensors are typically installed on specific products to measure product performance parameters such as angles. Since the working environment of attitude sensors can vary significantly, affecting zero position and sensitivity drift, they must be calibrated after production, manufacturing, and assembly to ensure accuracy. The product's angular posture generally requires calibration. For example, column-type weighing sensors, tilting during use can cause a decrease in mechanical properties. Tilt compensation is an effective method for improving their mechanical properties. The accuracy of the angle and azimuth calibration of the tilt sensor during tilt compensation is crucial. Conventional calibration devices use fixed-size tooling to define product position, making it difficult to eliminate the effects of dimensional errors in product processing. Calibration accuracy is limited to ±0.1° for tilt angles and approximately 2° for azimuths, resulting in significant errors in tilt testing and compensation.

[0003] In the prior art, a patent application with application number (CN202320139141.6) discloses a posture sensor angle calibration device, which includes a fixed bracket, a multi-directional displacement component, a rotating component, a first positioning component and a second positioning component. The fixed bracket includes an upper end frame and a base; the multi-directional displacement component is arranged on the base; the rotating component is arranged on the multi-directional displacement component; the first positioning component is used to position and carry the first end of the workpiece, is arranged on the rotating component and can drive the workpiece to rotate with the rotating component; the second positioning component is arranged on the upper end frame, for positioning the second end of the workpiece, and the multi-directional displacement component is used to drive the first end to move in one or more directions to change the offset angle of the axis of the workpiece relative to the vertical line. The second positioning component and the first positioning component also jointly fix the axis of the workpiece after the position of the workpiece is determined. The above device can realize high-precision calibration of the posture sensor angle.

[0004] The multi-directional displacement increase and rotation component is added to the existing technology, which effectively solves the problem that the conventional calibration device uses fixed-size tooling to limit the product position, and it is generally difficult to eliminate the influence of product processing size errors. The calibration accuracy can only be calibrated to a tilt angle of ±0.1° and an azimuth angle of about 2°, which will cause large errors in tilt testing and compensation. However, due to its overly complex structure, it cannot be repaired in time after being damaged, and thus it will not be practical in daily life. Utility Model Content

DETAILED DESCRIPTION

[0019] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] First embodiment

[0021] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the first embodiment of the present invention. Figure 2 It is an overall front view of the first embodiment of the present utility model.

[0022] The present invention provides an angle calibration device for a posture sensor 106, comprising a base 101, a support column 102, a top cover 110 and a sensor assembly, wherein the sensor assembly comprises a power source 103, a sliding frame 107, a sensor 106, a sliding block 108, a blocking block 109, a transmission column 104 and a placement plate 105. The aforementioned solution solves the problem of adding the multi-directional displacement increase and rotation assembly in the prior art, thereby effectively solving the problem that the conventional calibration device uses a fixed-size tooling to limit the product position, and it is generally difficult to eliminate the influence of the product processing size error. The calibration accuracy can only be calibrated to an inclination angle of ±0.1° and an azimuth angle of about 2°, which will cause a large error in the tilt test and compensation. However, due to its overly complex structure, it cannot be repaired in time after being damaged, and thus it will not be practical in daily life. It can be understood that the aforementioned solution can be used when the workpiece or component to be measured passes through The sliding block 108 slides on the sliding frame 107, thereby sending the workpiece or component to the bottom of the sensor 106. When the workpiece or component reaches the specified position, the power source 103 will provide power, and the transmission column 104 will transmit the power to the sensor 106 on the placement plate 105, thereby completing the angle measurement of the workpiece or component. This will effectively solve the problem of adding the multi-directional displacement increase and rotation components in the prior art while retaining the original effect, thereby effectively solving the problem that the conventional calibration device uses a fixed-size tooling to limit the product position, and it is generally difficult to eliminate the influence of the product processing size error. The calibration accuracy can only be calibrated to an inclination angle of ±0.1° and an azimuth angle of about 2°, which will cause a large error in the tilt test and compensation. However, due to its overly complex structure, it cannot be repaired in time after being damaged, and thus it will not be practical in daily life.

[0023] According to this specific embodiment, the support column 102 is detachably connected to the base 101 and is located above the base 101. The top cover 110 is detachably connected to the support column 102 and is located at the end of the support column 102 away from the base 101. The power source 103 is detachably connected to the top cover 110 and is located below the center of the top cover 110. The transmission column 104 is detachably connected to the power source 103 and is located at the end of the power source 103 away from the top cover 110. The placement plate 105 is detachably connected to the transmission column 104 and is located at the end of the transmission column 104 away from the power source 103. Since the original structure is simplified, it will retain the original effect while effectively solving the problem that its structure is too complicated and it cannot be repaired in time after being damaged, thus it cannot be used in daily life.

[0024] Among them, the sensor 106 is detachably connected to the placement plate 105 and is located on the side of the placement plate 105 away from the transfer column 104. The sliding frame 107 is detachably connected to the base 101 and is located above the base 101. The sensor 106 is an important calibration and measurement component, and the sliding block 108 is the main component for transporting workpieces or components.

[0025] Secondly, the sliding block 108 is slidably connected to the sliding frame 107 and is located inside the sliding frame 107. The blocking block 109 is detachably connected to the sliding frame 107 and is located at one end of the sliding frame 107. The sliding frame 107 will provide sliding space for the sliding block 108, and the blocking block 109 will limit the sliding distance of the sliding block 108.

[0026] When using the present invention to calibrate the workpiece or component to be measured, the sliding frame 107 is slid by the sliding block 108, thereby sending the workpiece or component to the bottom of the sensor 106. When the workpiece or component reaches the specified position, the power source 103 will provide power, and the transmission column 104 will transmit the power to the sensor 106 on the placement plate 105, thereby completing the angle measurement of the workpiece or component. This will effectively solve the problem of adding the multi-directional displacement increase and rotation components in the prior art while retaining the original effect, thereby effectively solving the problem that the conventional calibration device uses fixed-size tooling to limit the product position, and it is generally difficult to eliminate the influence of product processing size errors. The calibration accuracy can only be calibrated to an inclination angle of ±0.1° and an azimuth angle of about 2°, which will cause large errors in tilt testing and compensation. However, due to its overly complex structure, it cannot be repaired in time after being damaged, and thus it will not be practical in daily life.
