A sampling device for anionic
synthetic detergents used in tableware relates to the field of tableware sample liquid sampling technology. Its main structure includes: a sample liquid collection box placed inside a base, with tableware placed within the box; rinsing nozzles connected to the outlet of a
peristaltic pump via pipes; a local unit receiving
point cloud data from a 3D vision camera and a
laser contour
scanner,
processing it, completing 3D modeling, calculating the inner surface area of the tableware, calculating the required
running time of the
peristaltic pump and sending the calculations to a PLC controller, and generating a rinsing
path plan; the PLC controller controlling the
peristaltic pump to start and stop according to the
running time, and controlling the first
robotic arm to move according to the rinsing
path plan, driving the rinsing nozzles to complete the rinsing of the tableware. This invention solves the problems existing in the measurement of the inner surface area of tableware and sample liquid preparation in the prior art, improving the accuracy and efficiency of sample liquid preparation for the detection of anionic
synthetic detergents in tableware.
