Abstract
Description
Technical Field
[0001] This invention relates to the field of precision measuring equipment technology, and more specifically, to a high-precision CCD visual flash measurement device. Background Technology
[0002] In industrial production and manufacturing processes, accurate measurement of component dimensions is crucial. Traditional measuring instruments, such as calipers and micrometers, are not only inefficient but also susceptible to human error, leading to inaccurate results. While 2D measuring instruments and CNC imaging systems offer high precision, their slow measurement speeds cannot meet the rapid inspection requirements of mass production. Projectors and stereo microscopes are complex to operate and require highly skilled operators. In recent years, with the continuous development of technology, flash meters have gradually been applied as a new type of measuring device. However, existing flash meters still have certain limitations in terms of measurement accuracy, measurement range, and measurement efficiency. For example, some flash meters have limited field of view, making it impossible to measure large objects in a single measurement; some flash meters have measurement accuracy that is difficult to reach the micrometer level, failing to meet the measurement requirements of high-precision components. Furthermore, existing flash meters are prone to measurement errors when handling objects with complex shapes.
[0003] In view of this, we propose a high-precision CCD visual flash measurement device. Summary of the Invention
[0004] The purpose of this invention is to provide a high-precision CCD visual flash measurement device to solve the above-mentioned technical problems.

The adjustment component consists of a first linear module, a fine-tuning mechanism, and a locking screw. By tightening or loosening the locking screw, the ring frame can move up and down on the adjustable support, thereby adjusting the position of the CCD camera and improving the detection quality of the CCD camera.

The loading mechanism 3 is placed on the mounting structure 2 and includes an electric high-precision two-dimensional loading stage 31. The electric high-precision two-dimensional loading stage 31 has a left fixing groove 32 on one side and a discharge port fixing groove 33 on the other side. The electric high-precision two-dimensional loading stage 31 also has a right fixing groove 34. The electric high-precision two-dimensional loading stage 31 is a circular plate structure. There are two discharge port fixing grooves 33, which are equidistantly distributed on the electric high-precision two-dimensional loading stage 31 along with the left fixing groove 32 and the right fixing groove 34. The electric high-precision two-dimensional loading stage 31 is fixed on the detection working surface 21. The electric high-precision two-dimensional loading stage 31 has three grooves, which are distributed in a herringbone pattern. The electric high-precision two-dimensional loading stage 31 is located at the center of the detection working surface 21 and is located directly above the avoidance through hole 22. The detection mechanism 4 is placed on the loading mechanism 3 and includes a detection component 41 and an adjustment component 42.

The detection component 41 is located above the left fixed groove 32 and is fixed on the detection working surface 21. The adjustment component 42 is located on the right side. Above the fixed groove 34, and with the adjustment component 42 fixed on the detection working surface 21, the upper and lower adjustment bracket 412 is provided with an upper ring frame 415 and a lower ring frame 416 on the side facing the loading mechanism 3, wherein the upper ring frame 415 is placed above the lower ring frame 416.

This feature avoids the imaging error caused by changes in the object's position in traditional measuring equipment, ensuring the accuracy of the measurement.
[0024] Working Principle: This embodiment provides a high-precision CCD visual flash measurement device. In use, firstly, two workpieces to be measured are placed on the electric high-precision two-dimensional stage 31 located in the feeding port fixing slot 33. By operating the control button, the electric high-precision two-dimensional stage 31 begins to rotate, adjusting the workpieces to the second detection position. The high-precision CCD visual flash measurement device is then activated. The high-pixel CCD camera acquires the image of the object formed by the optical imaging system and quickly transmits the image data to the image processing system via an Ethernet card. After the workpiece at the second detection position is detected, the electric high-precision two-dimensional stage 31 continues to rotate. At this time, more workpieces to be measured can be placed in the feeding port fixing slot 33. Then, by tightening and loosening the locking screw, the laser can be moved left and right on the left-right adjustable device 424. This allows for fine-tuning of the focal length, light source position, and angle of the optical imaging system to adapt to objects of different sizes and shapes, ensuring measurement accuracy. The high-performance processor in the image processing system performs preprocessing such as noise reduction and enhancement on the image. Then, the measurement software quickly captures the object's outline image according to pre-programmed instructions and compares it with the size scale formed by the camera's tiny pixels to calculate the object's size and shape parameters. The measurement software evaluates the dimensional tolerances of the calculation results and generates a measurement report. At this point, the workpiece to be measured can continue to be placed into the fixed slot 33 at the feeding port, allowing the program to perform uninterrupted inspection, thereby improving inspection efficiency.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
