MIB-100 Manual Inspection Booths
Model MIB-100 (Current Version is: 2.3.5)
The Manual Inspection Booth (MIB-100) in Production Configuration is shown in Figure 1 below. The MIB-100 is designed to provide a uniform illumination work envelope and consistent inspection environment. The framework of the MIB-100 is ergonomically designed and implements a recently patented balanced lighting system that generates a 9.7 Liter inspection volume in which light intensity is held within 10%, thus eliminating a major component for inspection data variability. This large accurate inspection volume allows the inspector to easily position the sample in the chamber.

The Production Configurations MIB-100 is designed to handle higher inspection volumes and is customized to meet the material handling used in your facility. The side shelves a designed to fit the trays that are used to hold production product in your facility. They provide adjustments for 2 axis of rotation and 3 linear translations to make the shelve position "just right" for each individual inspector. Best of all, the adjustments do not require any tools! The locking screws have ratcheting handles that allow the inspection crew to make their own adjustments for optimum comfort.

Figure 4. Light Intensity Map of MIB-100
Consistent inspection results require consistent light intensity within the inspection volume. The MIB-100 provides the most uniform light intensity within an inspection volume available in a commercial product. The lighting technique is so unique that it is patented! Most lighting booths offer a single light source that is usually mounted above the inspection volume. This top lighting technique produces a non-uniform inspection volume that can have light intensity variations of more than 200% over a very short distance (i.e. <50 mm). The probability of detection is directly related to the amount of light in the inspection volume. Top lighting technology makes it very difficult for inspection teams to achieve consistent inspection results. The MIB series of manual inspection booths have a relatively "flat" inspection volume with constant light intensity values. The plot in Figure 4 above is representative of the lighting map found in the MIB-100 product.
Inspection Sequence and Duration
All MIB-100 models include a programmable logic controller integrated into the system to pace the operator inspection time. The PLC / operator interface insures that samples are inspected for a designed amount of time and that the result of the inspection disposition is correctly recorded. This is done using a small flat panel display mounted just below eye level on the left side of the booth (or flush mount on the Solid Surface armrest/shelf as in the standard configuration) and within the sight of the inspector.
The backlight color on the operator interface panel will indicate the mode of operation. The color is green when the system is in a "Setup" mode; this mode allows the supervisor to review results, set inspection parameters and the inspector to enter the "Inspection" mode and to review results when the inspection shift ends. The screen color is orange at the beginning of the light background particle inspection. During the actual inspection period the screen will display a graphic count down timer and a red LED light will appear just to the right of the inspection area. When the LED turns off the inspection period is complete and the screen will then be illuminated with a red background. The red background indicates that the dark background inspection is about to begin. When the dark background inspection is active a green LED just to the left of the dark background inspection area is illuminated. When the Green LED turns off the dark background is complete and the operator interface background turns green and requests the inspection result to be entered. The inspector must then select, Re-inspect, Good or Bad to return to the Light Background inspection screen.
The inspection system may also be setup for 18% Gray Card Inspection. The gray background inspection screen will be illuminated with an orange background. Once the "Start Gray Test" button is depressed the screen turns red and both LED in the the inspection area are illuminated during the inspection period. When the allotted inspection time has expired the LED's turn off and the screen turns green. The inspector must then select, Re-inspect, Good or Bad to return to the Gray Background Inspection screen.
The inspection results may viewed by depressing the "Results" button on the Main screen. The system will reconcile up to 65,535 inspected containers.
