The spray detection grating uses
synchronous scanning to identify the blocked channel; the illuminator
channel emits a light pulse and the corresponding receiver
simultaneously looks for the pulse, and when found, completes a channel
scan and then moves to the next channel until all scans All done. When a
cycle scan is completed, the system records those channels through, and
those channels are occluded. A signal is output according to the system
definition. The signal can be an analog signal, a digital signal, or an
RS485 communication signal.
The photoelectric scanning system
is an automatic control device for spraying surface, which is composed
of a set of sensors. The sensor is composed of a transmitter and a
receiver. The infrared sensors are connected to the controller through
signal lines, and the transmitter and the receiver are disposed at the
entrance of the spraying machine. In front. The aluminum alloy profile
to be sprayed is suspended from the moving bracket, passes between the
transmitter and the receiver at a constant speed, and then passes
through the automated nozzle. The sensor detects the length of the
aluminum alloy profile through the infrared receiver and transmits the
signal to the controller. The controller calculates the time delay
according to the distance between the receiving seat and the spraying
machine and the moving speed of the moving bracket, and controls the
spraying machine to arrive at the aluminum alloy profile. Change the
vertical round-trip distance of the gun to avoid spraying the paint in
the neutral position, saving paint and reducing pollution.
