The image measuring instrument is a precision measuring instrument integrating light, electricity and machinery. It needs regular and good maintenance to keep the instrument in good condition. Only in this way can the original accuracy of the instrument be maintained and the service life of the instrument be extended.
1. The instrument should be placed in a clean and dry room (room temperature 20℃±5℃, humidity below 60%) to avoid contamination of the surface of optical parts, rust of metal parts, and dust and debris falling into the moving guide rails, which will affect the performance of the instrument.
2. After the instrument is used, the working surface should be wiped clean at any time, and it is best to cover it with a dust cover.
3. The transmission mechanism and moving guide rails of the instrument should be lubricated regularly to make the mechanism move smoothly and maintain a good condition.
4. If the workbench glass and paint surface are dirty, they can be wiped clean with neutral detergent and clean water. Never use organic solvents to wipe the paint surface, otherwise, the paint surface will lose its luster.
Image measurement can be roughly divided into three methods: contour measurement, surface measurement, and z-axis measurement.
1. Contour measurement:
As the name implies, it is to measure the contour edge of the workpiece. Generally, the bottom contour light source is used. When necessary, surface light can be added for auxiliary lighting to make the measured edge clearer and facilitate measurement.
2. Surface measurement:
Surface measurement can be said to be the main function of image measurement. All visible surface graphic dimensions of objects can be measured by image measuring instruments under surface light source illumination, such as the copper foil size of circuits on circuit boards, IC circuits, etc. When the measured object is black plastic or glue, the image measuring instrument can also easily measure its size.
3. Z-axis measurement:
When equipped with a high-power objective lens and sufficient aiming and positioning accuracy, the image measuring instrument can perform Z-axis measurement, such as measuring the step height and dark hole depth of the workpiece, and surface light illumination is used during measurement. For specific measurement methods, please read 《DC3000 Operation Manual》 or 《QMS3D.M User Manual》. The optional RENISHAW simple probe (MCP) can be used to measure height and some simple geometric tolerances: flatness, parallelism, cylindricity, verticality, etc. For detailed usage, see 《QMS3D-M User Manual》.
