In the present embodiment, it is connected by screw bolts between tooling bindiny mechanism 4 and work station frame 1, pacifies as stablizing
Fill origin reference location face.Using bolt and positioning pin (3 nail, 2 pin) connection between tooling bindiny mechanism 4 and positioning tool 5, convenient for not
It is switched fast between product tooling.Product Fixture Design has L-type locating piece 51, and it is fixed to be adjusted using adjustment bolt 55 and adjusting pad
Position pins position is set, and is quickly adjusted convenient for product tooling.The positioning tool 5 of every kind of workpiece is provided with RFID chip, and tooling is installed to
Control program detects the radiofrequency signal of RFID chip automatically behind position, checks whether tooling code name and the program of product to be detected are right
It answers.
In the present embodiment, detection work station can detecte geometric dimension (length × width × height) in 1200mm × 500mm
Automobile metal plate work within the scope of × 400mm, different automobile metal plate work products need to work out unique detection program.The program will
Guided robot moves unique track, meets the shooting needs of NI Vision Builder for Automated Inspection.
When detecting different products, one-to-one positioning tool 5 therewith is only needed to change.RFID is installed in every set tooling
Chip, when operator is attached it in 5 bindiny mechanism 4 of positioning tool, automatic detecting tool is numbered and is detected by RFID chip
Program whether successful matching, and operator is required to confirm.After the installation is completed, operator installs workpiece to be checked to positioning tool 5
In place, operator's one-key start detects program.According to the detection complexity of different product, general detection time is in 3- 5
Second (it is about 1 second that robot, which shoots the shooting time of every photos).
Workpiece A to be detected, i.e. automobile metal plate work structure are generally designed with according to design conditions, typically more complexity
Location hole and face.Machine vision technique needs simply to be positioned when being detected, using the both ends location hole of the sheet metal component
With plane as positioning datum, workpiece need to be only installed on positioning pin by operator.The positioning tool 5 design has mistake proofing machine
