DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0021] like Figure 1-Figure 13 As shown, an embodiment of the present invention provides a high-speed online measuring device suitable for a centerless grinder, comprising: a cleaning and docking component 1, a groove guiding component 2, a measuring component 3, a driving component 4 and a sorting component.

[0022] Specifically, the cleaning and docking assembly 1 is used to guide the workpiece a to be measured from the discharge port of the centerless grinder to one end of the groove guide assembly 2, that is, one end of the cleaning and docking assembly 1 corresponds to the discharge port of the centerless grinder, and receives the workpiece a to be measured and then transports it downward, and the other end of the cleaning and docking assembly 1 corresponds to the groove guide assembly 2, so that the workpiece a to be measured is transported to the groove guide assembly 2, and the cleaning and docking assembly 1 plays a role of guiding and docking. The cleaning and docking assembly 1 performs air blowing cleaning on the workpiece a to be measured, specifically: the workpiece a to be measured is in the cleaning and docking assembly 1 During the transportation process, the blowing structure (spiral air pipe 103) in the cleaning docking component 1 blows air to clean the workpiece a to be measured, so that the grinding fluid, grinding dust, etc. in the workpiece a to be measured are blown off, and the surface of the workpiece a to be measured is relatively clean, so as to facilitate subsequent measurement. Overall, the cleaning docking component 1 plays the role of docking and transportation and cleaning the surface of the workpiece a to be measured. The groove guide component 2 is arranged at one end of the cleaning docking component 1, and the axial direction of the workpiece a to be measured is along the length direction of the long groove 202a of the groove guide component 2. The long groove 202a It is used to guide the workpiece a to be measured, that is, the workpiece a to be measured is axially along the length direction of the long slot 202a of the groove guide component 2, so that the workpiece a to be measured can slide along the length direction of the long slot 202a of the groove guide component 2. The driving component 4 is installed above the groove guide component 2, and the driving component 4 is used to drive the workpiece a to be measured to move along the length direction of the long slot 202a of the groove guide component 2. The driving component 4 provides power to drive the workpiece a to be measured to slide along the length direction of the long slot 202a of the groove guide component 2. The measuring component 3 is fixedly installed on the groove guide component 2, and the measuring component 3 measures the workpiece a to be measured along a direction perpendicular to the length direction of the long slot 202a. The measuring component 3 uses the currently commonly used image measuring equipment. The sorting component classifies and transports the workpieces according to the measurement results of the measuring component 3. The sorting component is communicatively connected with the measuring component 3. For example, the measuring component 3 classifies the workpieces into three categories of "qualified products", "large size" and "small size" according to the measurement results, and the sorting component sends the workpieces into different conveying lines / collection frames according to the classification structure.

[0023] In this embodiment, through the designed cleaning and docking component 1, groove guide component 2, measuring component 3, driving component 4 and sorting component, efficient and automated measurement of the size of the workpiece a to be measured can be achieved. Compared with traditional manual measurement, the measurement efficiency is high and the accidental error is small. It is applied to repeated measurement of large-scale and small-sized workpieces, which can improve production efficiency, reduce labor costs and enhance corporate competitiveness.

[0024] The core of this solution is that the measuring component 3 measures the workpiece a along the length direction perpendicular to the long slot 202a; when the measuring component 3 measures the size of the workpiece a, it actually measures the length m of the workpiece protruding from the slot frame. In this measurement method, the image directly obtained by the camera module 302 of the measuring component 3 always has an edge (the bottom edge of the image) that remains horizontal. The image is scaled and placed in a plane rectangular coordinate system, and the Y-axis coordinate value of the top edge contour of the image is read to obtain the accurate length m of the workpiece protruding from the slot frame. For example, the Y-axis coordinate values ​​of 10-20 points are selected at equal intervals on the top edge contour of the image, and the length m of the workpiece protruding from the slot frame is obtained by calculating the average value after removing the maximum and minimum values, and then the formula is used to calculate the length m of the workpiece protruding from the slot frame. , calculate the diameter D of the workpiece to be measured, where n represents the spacing (fixed value) where the groove guide assembly supports the workpiece to be measured; compared with the traditional algorithm for reading the diameter of the workpiece a to be measured in the plane image, this method has a simpler algorithm and more accurate measurement results.
