releasing work on a control console, and processing different works by a robot according to the release work and the ordering judged by the logic of the current situation;
wherein, the lathe material loading includes:
the robot conveys the trays of the corresponding products to the machine tool, firstly, the trays are placed on a platform to be processed, an automatic door is opened, the robot takes an air gun to blow off and clean the clamping surface inside the machine tool, then the air gun is put down, the trays are taken from the platform to be processed, and the trays are sent to the machine tool;
after the clamping is confirmed, the ground rail robot is separated from the tray and exits;
after the machine tool is generated, the ground rail robot enters, blows up and cleans, takes out the tray, and conveys the tray to a material inlet and outlet of a cleaning dryer or a three-coordinate instrument;
cleaning or measuring the product;
the ground rail takes out the trays from the robot and transfers the trays to a finished tray warehouse;
the robot gets the air gun and blows off the clearance to the inside clamping face of lathe, then puts down the air gun, gets the tray from waiting material platform.
10. The production method of claim 9, wherein the manual door is not opened at ordinary times, and when a special condition is met in the production line or maintenance is needed, the manual door is opened to enter the production line for working, and the whole production line is in a stop state, and each link is suspended;
when the automatic door is in a manual state, the automatic door is completely closed, equipment in the production line does not work, and the machine tool is manually operated at the moment;
when the robot is in a semi-automatic state, the robot and the person can work in a collinear mode, the automatic door is in a normally closed state, the robot cannot go to the position of a manual operation machine tool for loading and unloading, the automatic door can be opened after the robot is in place, at the moment, the ground rail robot detects the front area of the machine tool through the detection radar, and loading and unloading are stopped and an alarm is given if redundant objects are found;
when in the full-automatic state, the automatic door is fully opened, and personnel cannot enter the operating machine tool.
11. The method of claim 9, wherein the robotic handling of different jobs further comprises: machine tool blanking, cleaning machine feeding, cleaning machine blanking, three-coordinate feeding, three-coordinate blanking, feeding through a feeding hole and discharging through a feeding hole.
