An automatic painting apparatus for cylindrical sheet-like workpieces according to claim 2, wherein: the rotary table component is composed of a rotary motor and a supporting plate, the rotary motor is fixedly installed in the rack, and the supporting plate is fixedly installed on an output shaft of the rotary motor.

8. An automatic painting apparatus for cylindrical sheet-like workpieces according to claim 2, wherein: the spraying assembly comprises first servo motor, mounting bracket, first unipolar robot, second servo motor, point gum machine, second unipolar robot, second elephant trunk and first elephant trunk, mounting bracket fixed mounting is in the frame, first unipolar robot installs on the mounting bracket, first servo motor installs on first unipolar robot, first elephant trunk is installed on first unipolar robot slider, second unipolar robot installs on first unipolar robot slider, second servo motor installs on second unipolar robot slider, the second elephant trunk is installed on second unipolar robot slider, the point gum machine is installed on the second elephant trunk.

9. An automatic painting apparatus for cylindrical sheet-like workpieces according to claim 2, wherein: two groups of spraying components are arranged in the rack, and the included angle between each spraying component and the left and right neutral surfaces of the rack is 20-45 degrees.

10. A method of operating an automatic painting apparatus for cylindrical sheet-like workpieces according to any one of claims 1 to 9, characterized by: the method comprises the following steps:

the method comprises the following steps: manually placing the workpiece in a positioning hole on a template in the feeding unit, wherein the template in the feeding unit is positioned at a lower limit position;

step two: a lifting cylinder in the feeding unit rises to an upper limit position, the workpiece is separated from a positioning hole of the template, and then a conveying line body in the feeding unit moves forward by one step;

step three: the plane joint robot sucks a workpiece on a material taking position on a conveying line body in the material feeding unit through a sucking disc on the clamp, places the workpiece in the left weighing unit, weighs and records the weight;

step four: the plane joint robot conveys the weighed workpiece to a supporting plate on a turntable assembly in the paint spraying unit through a sucking disc on a clamp;

step five: a driving motor in a positioning clamp in the paint spraying unit acts to drive a left finger and a right finger to act synchronously, so that the positioning operation of a workpiece is realized;

step six: the positioning clamp in the paint spraying unit is reset to an initial opening state, and a lifting pressure head in the paint spraying unit moves downwards through a cylinder with a guide rod until the pressure head presses the top surface of a workpiece;

step seven: two groups of paint spraying components in the paint spraying unit move the dispensing heads to a paint spraying working position through the driving of a first servo motor and a second servo motor;

step eight: a glue dispensing head in a paint spraying assembly in the paint spraying unit starts paint spraying operation, meanwhile, a rotary table assembly in the paint spraying unit drives a workpiece to rotate through a rotating motor, and an air suction pipe in a lifting pressure head in the paint spraying unit starts air suction purification operation;

step nine: after the paint spraying assembly in the paint spraying unit finishes paint spraying, the lifting pressure head resets to an upper limit position, the paint spraying assembly resets to an initial state, the rotating motor in the rotary table assembly stops rotating, and at the moment, the plane joint robot conveys the painted workpiece to the right weighing unit for weighing and recording the weight;

step ten: whether the workpiece is qualified in paint spraying is judged through the difference between the weighing value of the right weighing unit and the weighing value of the left weighing unit, the plane joint robot conveys the workpiece to the blanking unit through the clamp after the workpiece is qualified in paint spraying, and the workpiece on the blanking position in the blanking unit is blanked manually, so that the circular operation is realized, and if the workpiece is unqualified in paint spraying, the plane joint robot places the unqualified workpiece in an unqualified area through the clamp.
