II. Instrument structure and working principle

Optical imaging measurement is one of the more advanced precision and efficient measurement methods at present. Its working principle is shown in Figure 1. The workpiece to be measured (placed on the working After being illuminated by the LED surface light (5) or the bottom light (in the granite base), the image is captured by the zoom lens (6) and the color CCD camera (in the outer cover 11), and then sent to the image capture card (installed in the PC on the machine), the PC then reads the image capture card data for analysis and processing. The workpiece is placed on the workbench without moving, and the ball screw is driven by the stepper motor (controlled by the main board (9)). The ball screw then converts the rotary motion of the screw into the linear motion of the workbench (4). The workbench (4) Drive the optical ruler (13 and 15) to move in the X and Y directions. The M2D-CNC software issues commands to the main board, and the main board completes reading, motor control, light source control and other tasks. The working principle of the imaging system is shown in Figure 2.

The overall structure of the instrument can be divided into four parts (Figure 1):

1. The main structure of the instrument includes:

Granite base group (17), column (12), electric worktable (4) and ball screw drive driven by stepper motors in X, Y and Z directions Institutions (3; 10; 14).

2. Imaging system (for imaging aiming), including:

Zoom lens (6): zoom range 0.7~4.5×, total video magnification 34~220×.

Color CCD camera (inside the outer cover 11): converts the image captured by the zoom lens into an electronic signal, and then transmits it to the color display through the S-video.

Color display (7): Convert the video signal sent from the CCD camera into a television image.

Bottom light source (in the granite base)/Surface light source (5): Using adjustable brightness LED light source, the lighting effect is good, the lifespan is 10 times that of traditional light bulbs, the light source control is realized by the motherboard .

3. Control system:

Motherboard (9): All readings, motor control and light source control are realized by it. The computer host does not directly control it, but only sends commands to the motherboard. . For the motherboard wiring diagram, please see the attached figure (1)

Motion control of the X, Y, and Z axes can be achieved by switching the motion control keys (3) on the switch control panel (Figure 3).

Status description of the USB connection indicator light (5) on the switch control panel: The USB light is on, indicating that the USB cable is connected; the USB light flashes, indicating that data exchange is in progress.

4. Digital measurement system, including:

X-axis (13), Y-axis (15), Z-axis (8) optical ruler: convert geometric displacement into digital information

The Z axis is generally used for auxiliary measurement.

M2D-CNC professional software: Professional software independently developed by our company, used to send commands to the motherboard and process the image acquisition card to realize graphic measurement and data processing functions.

3. Unpacking and installing the instrument

1. Remove the outer and inner packaging of the instrument, take out the instrument instruction manual, and read this section first.

2. Move the main body of the instrument to the positioning table, install the foot screws, and use a level to level the instrument.

3. Remove the X, Y axis fixed plate and Z axis fixed plate, and the X, Y, Z axis can be transmitted.

4. This machine uses AC110V/220V power supply, 90-130Hz/180~240Hz. Connect the monitor, turn on the instrument power, and the instrument installation is completed.

5. Before using the instrument, please be sure to read the instructions provided carefully.

6. Instrument installation and inspection before use are generally undertaken by the supplier.

IV. Instrument measurement methods:

Image measurement is roughly divided into three methods: contour measurement, surface measurement, and Z-axis measurement.

1. Contour measurement:

As the name suggests, it is to measure the contour edge of the workpiece. Generally, the bottom contour light source is used. If necessary, surface light can also be added as auxiliary lighting to make the measured edge clearer. , which is beneficial to measurement.

2. Surface measurement:

Surface measurement can be said to be the main function of image measurement. For all visible surface graphic dimensions of objects, under surface light source illumination, image measuring instruments can almost It can measure everything, such as the copper foil size of lines on circuit boards, IC circuits, etc. When the object to be measured is black plastic or rubber, the image measuring instrument can easily measure its size.

3. Z-axis measurement:

When equipped with a high-magnification objective lens and with sufficient aiming and positioning accuracy, the image measuring instrument can perform Z-axis measurement, such as measuring the step height of the workpiece. , dark hole depth, use surface light illumination when measuring.

For detailed usage instructions, see the M2D-CNC software instruction manual

5. Instrument maintenance and upkeep:

The image measuring instrument www.mitutoyo-17.com is a Precision measuring instruments that integrate light, electricity, and mechanics require regular and good maintenance to keep the instrument in good condition, so that the original accuracy of the instrument can be maintained and the service life of the instrument can be extended.

1. The instrument should be placed in a clean and dry room (room temperature 20℃±5℃, humidity below 60%) to avoid surface contamination of optical parts, rust on metal parts, and dust and debris falling into the movement On the guide rail or marble guide strip, it will affect the performance of the instrument.

2. After using the instrument, the working surface should be wiped clean at any time, and it is best to put on a dust cover.

3. The screw nut transmission mechanism and motion guide rail of the instrument should be lubricated regularly to make the mechanism move smoothly and maintain good use condition. If there is insufficient lubrication, friction and wear will increase, causing failure or shortening service life.

It is recommended to use bearing lubricating oil for ball screw oil lubrication and lithium soap-based grease for grease lubrication.

The appropriate viscosity of oil is ISO VG32~150. The higher the viscosity, the better. If oil is used for lubrication, the amount of oil injected should be about 1/3 to 1/2 of the nut space.

4. If the workbench glass and paint surface are dirty, they can be wiped clean with neutral detergent and water. Never use organic solvents to wipe the paint surface, otherwise the paint surface will lose its luster.

5. The LED light source of the instrument has a long service life, but when a bulb burns out, please notify the manufacturer and a professional will replace it for you.

6. The precision components of the instrument, such as X and Y guide mechanisms, imaging systems, worktables, optical rulers and Z-axis transmission mechanisms, have been precisely adjusted, and all adjusting screws and fastening screws have been fixed. , customers are not allowed to disassemble it by themselves. If there are any problems, please notify the manufacturer to solve them. Instrument failure or reduced accuracy caused by self-disassembly is not covered by the warranty.

7. Generally, all electrical connectors of the instrument should not be unplugged. If they have been unplugged, they must be correctly inserted back according to the markings and the screws must be tightened (as shown in Figure 4). Improper plugging may affect the function of the instrument at least, or damage the system at worst.
