Description

Technical Field

[0001] This utility model relates to the technical field of image measurement equipment, specifically to a multi-angle image measurement instrument. Background Technology

[0002] Vision measuring instruments primarily perform measurements using non-contact methods. Fully automatic vision measuring instruments are widely used in the measurement of various precision parts, enabling measurements to be taken in areas that are difficult to reach with calipers or angle gauges.

[0003] For example, CN218937307U discloses a multi-hole imaging measuring instrument, relating to the field of imaging instrument technology. Specifically, it discloses a fully automatic imaging instrument, including a base, a support on the base, a camera on the support, and a placement plate on the base. The placement plate has a fixing plate, and a limiting rod passes through the fixing plate in a horizontal direction. A locking bolt is threaded onto the side wall of the fixing plate, and the locking bolt abuts against the side wall of the limiting rod. At least two fixing plates are provided along the circumference of the placement plate. This utility model allows a movable limiting rod to abut against an irregularly shaped workpiece, and then the limiting rod is fixed by locking bolts, thus facilitating the limiting of the irregularly shaped workpiece. The multiple fixing plates ensure the reliability of the limiting of the irregularly shaped workpiece.

[0004] Existing image measuring instruments often encounter workpieces that are not dust-free and contain debris. After measurement, this debris and dust may remain on the placement plate, which can become dirty over time, affecting the measurement results. This necessitates manual wiping, reducing work efficiency. To address these issues, patent application CN202420950509.1 discloses an image measuring instrument comprising: a base; a placement plate on the base for placing workpieces; a support mounted on the base, housing a camera and a lifting assembly; the lifting assembly driving the camera to move up and down; a moving device positioned between the placement plate and the base, capable of moving the placement plate forward, backward, left, and right to adjust the position of the workpiece in the camera's view; and a cleaning device mounted on the placement plate, comprising a swing motor and a cleaning rod; the swing motor is connected to the cleaning rod, driving it to swing and clean the placement plate. Dust from the workpiece can soil the placement plate. A cleaning device can be installed to clean the plate, reducing errors in the detection results caused by dust and eliminating the need for manual wiping, thus increasing work efficiency. However, existing image measuring instruments have the following problems: They typically rely on the X and Y axis movement of the worktable to achieve planar measurement of the workpiece. However, for workpieces with complex three-dimensional structures or those requiring measurement of side features, the fixed angle of the imaging device makes it difficult to acquire images of the workpiece's side or inclined surfaces, limiting the measurement range. Furthermore, to measure different angles, manual adjustments to the workpiece's posture or the image component angle are usually required, which is cumbersome, inefficient, and prone to introducing human error. It also makes it difficult to achieve comprehensive, blind-spot-free measurement, impacting overall measurement efficiency. Utility Model Content
