Special Features

Implements the highest detection power possible with the KEYENCE pioneered “Color gradation processing” (Patent pending).

• Reliably detects only the designated colors.

Enables the reliable extraction of targets that are hard to differentiate with conventional monochromatic processing. (e.g. differentiation of yellow on white, dark blue from black, and gold plate from silver plate, etc.) A change of background colors does not require a change of settings, because the CV-701(P)/751(P) detects the registered colors exclusively.

• Shadows on the target surface do not cause malfunctions.

Detection is unstable with conventional monochromatic processing, which detects the brightness of the target, because it is affected by shadows given by the shape of the targets and by the varied illumination distributions. Color concentration processing enhances stability dramatically because detection is based on the color differences.

■ Operating principals

The CV-701(P)/751(P) converts the color signal of the image captured by the camera into R/G/B/ digital data using an A/D converting circuit.

It obtains the data of R-G, G-B, R-B based on the converted digital data. The measurement area for the color extraction is set based on six parameters. The [AREA] mode (color binary conversion processing) operates detection by judging whether the measured values are within or outside the color extraction area. The colors within the color extraction area are of the maximum gradation level (255 levels of gray) with color concentration processing. The CV-701(P)/751(P) operates gray processing by converting the color data into a monochromatic image so that the level is reduced as the color falls outside the area. This processing method realizes stable detection for colors with different values but with the same hue, and for colors without a hue such as white, black, and gray.

Simple operation for highly sophisticated image processing functions. Saves boot-up time dramatically.

• Simple “click extraction”: Simply place and click the cursor on the color area to be detected to set the colors for extraction. No complicated parameter settings are necessary.

Setting is simple enough for first-time use for sophisticated image processing.

Loaded with special features

• The screen-saving function allows you to go back and check a former detection screen.

• The CompactFlash memory comes standard with the CV-701(P)/751(P). Back up of the detection hysteresis and multiple programs, and copying between controllers can be operated easily without using a personal computer.

• The measurement result can be output in analog voltage (0 to 4 V).

Chapter 3 Mode Selection

3.1 Measurement Modes and Typical Applications

The CV-701(P)/751(P) features five measurement modes: “ARE/CON” (Area continuous), “INS/TRG” (Inspection trigger), “INS+POS” (Inspection + position), “ABS.POS” (Absolute position), and “REL.POS” (Relative position). This section gives an overview and describes the typical application of each mode.

3.1.1 “ARE/CON” (Area continuous)

Use “ARE/CON” mode to continuously measure the area in the window for selected color data.

➮

See“4.4 “AREA” Mode Basic Settings” on page 57 for the setting procedure.

Functions

• Extracts the selected color data of the window.

• Sets a window and measures the area of the selected color data and the

background color of the window.

• Up to eight windows can be drawn for a single program. The measured data and detection result for each window are output sequentially.

Sample: Detection for the number of pixels

T ypical applications

Use the “AREA” mode for detection of the presence or absence of a target, a missing target, and for the shape or area of a target.

Page 29

Chapter 3 Mode Selection

Basic Unit of Area: “Pixel”

The sensing element CCD of the camera forms a square grid pattern, and each minute area corresponds with a pixel. Each pixel recognizes R, G, and B as a 256level brightness signal.

“AREA” mode allows you to set a window on a desired part of an image on the monitor screen and count the number of pixels matching the selected color data. You can detect the area of a target, whether it is small or large, and the presence or absence of a target.

3.1.2 “INS/TRG” (Inspection trigger)

Use “INS/TRG” mode to measure the selected color data in the window at every trigger input.

➮

See “4.6 “INS” Mode Basic Settings” on page 70 for setting procedure.

Functions

• Selects the measurement parameter by the inspection mode.

• The following ten inspection mode types can be selected from the inspection

mode.

• Setting an inspection mode for each window allows for multiple detections with one target.

AREA

Detects the presence or absence of a target, whether it is small or large, a missing target, and the area of a target as with “ARE/CON” mode.

OUTER (Outer edge)

Measures the distance between the outermost edges in the window.

INNER (Inner edge)

Measures the distance between the innermost edges in the window.

GAP

Measures the distance between the odd-numbered edges and the even-numbered edges counted from the left (in horizontal scanning) or top (in vertical scanning) of the window. The maximum, minimum, and average values can be obtained.

EDGE NO (Edge count)

Use this mode to count the number of pins. Counts the number of edges in the window. (Specify the edge with [WH ➞ BL] or [BL ➞ WH].)

COUNT

Counts the number of clusters of extracted colors in the window. Up to 256 clusters can be counted.

POINT (Point sensor)

Detects the presence or absence of the extracted colors of the set point. Up to 8 points can be detected in a window.

STAIN

Use this mode to detect stains and defects. The four types that can be used for a window: square, circle, ring, and arc.

GRAVITY

Detects the center of gravity and the angle of principal axis (the longitudinal angle) of a target.

Detecting the center of gravity of alignment marks

GRAVITY

Detects the center of gravity of alignment marks.

Unit Conversion Function

The CV-701(P)/751(P) processes an image and obtains data with the number of pixels. For example, measuring a target with an outer size of 3.25 mm may give

65.0 pixels. The unit conversion function converts the number of pixels into other

units such as mm.

➮

See page 137.

3.1.3 “INS+POS” (Inspection + position)

Use the “INS+POS” mode to adjust the position and angle of the window. Use this mode for trigger detection when the “INS/TRG” mode can’t be used because the position of the target is not constant.

➮

See “4.6 “INS” Mode Basic Settings” on page 70 and “4.9 “Position Detection” Mode Basic Settings” on page 109 for the setting procedure.

■ Position adjustment

Use this function when detection cannot be operated at the same position in a window because the position of a target is not constant in field operation. Using the position adjustment function allows the inspection window to adhere to the motion of targets. The position adjustment, like the “ABS.POS” mode, uses either “pattern search” or “edge detection” to recognize the distinctive image and edge of a target. It then adjusts the inspection window to adhere to the target. This function allows the CV-701(P)/751(P) to constantly detect the same position of targets regardless of the movement of targets. Also, the rotation adjustment function allows the CV701(P)/751(P) to automatically tilt the inspection window when the target makes a rotating movement.

Chapter 4 Setting Procedure

4.4 “AREA” Mode Basic Settings

Set the “AREA” mode from “ARE/CON” mode for continuous detection, and select “AREA” from “INS/TRG” for detection using the trigger signal input. This section

describes the basic setting procedures using the “ARE/CON” (Area continuous) mode.

4.4.1 “AREA” mode

■ Difference between “ARE/CON” (Area continuous) and “INS/TRG” (Inspec-

tion trigger)

“ARE/CON” detects a target continuously. “INS/TRG” can be used for area detection, but it detects a target only when a trigger signal is input. Both modes are set using the same procedure.

■ Resolution of image

The images picked up with the CV-701(P)/751(P) are composed of the primary colors R (red), G (green), and B (blue), and each color has 256 color levels from 0 through 255. For example, a color with R=200, G=50, B=40 is a reddish color, and a color with R=150, G=150, B=150 is white. The data of R-G, G-B, and R-B are obtained based on the R, G, B data, and the area is set for the six parameters to operate color extraction. The color screen processes an image by 16,770,000 resolutions compared to the monochromatic gray mode that processes colors from white to black with 256 levels. This color mode enables target differentiations that cannot be distinguished with a black and white mode.

■ Counting pixels

The CV-701(P)/751(P) counts the pixels of extracted colors in the MEASURE window and displays the number of pixels. You can set a tolerance (upper/lower limits) for the number of pixels to differentiate targets between acceptable and unacceptable. This enables detection of the presence or absence of components and the size of a target.

If the position or angle of the target is not constant on the screen, use the position adjustment function. Select “INS+POS” (Inspection + position) in the mode selection.

4.6.7 Basic setting procedure for the STAIN mode

Use the STAIN mode to detect stains in the window. Select a window shape from circle, square, circumference, and arc.

1) Set a small area in the window. The small area is called a “segment”. The average brightness is measured for each segment. (Change the size of segments with [SIZE].)

2) Measure all of the segments for brightness differentials between adjacent segments. The maximum differential in the window is measured.

3) When the measured value exceeds the set level, the stain is judged as unacceptable (defective).

This section describes the basic setting procedure for the STAIN mode.

1. First follow the “Basic setting procedures” (➮

page 36

) to set the

parameters to the color settings.

2. Set [MEASURE] (Measurement window)

Specify the size of the window used for measurement.

1) Place the cursor on [MEASURE] and press the [ENT] key. The window selection menu appears.
