10. The method for operating a semi-automatic assembly device for a folding shed according to any one of claims 1 to 9, characterized in that: It includes the following steps: Step 1: placing the upper rod in a corresponding placement area of ​​the upper rod feeding device (1), and moving it to the guide rail mechanism (7) after completing the preparation work on the upper rod feeding device (1); and placing the lower rod in a corresponding placement area on the lower rod feeding device (5), and moving the rod to the feeding mechanism (8) after completing the preparation work; Step 2: The upper rod is transferred to the rotating arm (7.4) of the guide rail mechanism (7) through the upper rod feeding device (1); the rotating arm (7.4) lifts the upper rod and transfers it to the upper transmission device (2) through the fan-shaped guide rail (7.3); the upper rod is fixed by the upper rod positioning clamp (2.2); the lower rod is transferred to the feeding mechanism (8) through the lower rod feeding device (5); the lower rod is transferred to the lower transmission device (3) through the feeding mechanism (8); and the lower rod is fixed by the lower rod positioning clamp (3.2); Step 3: The first drive motor (2.5) drives the upper transmission column (2.3) to rotate, driving the upper rod positioning clamp (2.2) on the upper transmission belt (2.1) to be transmitted to the working area of ​​the assembly mechanism (4); the second drive motor (3.5) drives the lower transmission column (3.3) to rotate, driving the lower rod positioning clamp (3.2) on the lower transmission belt (3.1) to be transmitted to the working area of ​​the assembly mechanism (4); Step 4: The first drive motor (2.5) of the upper transmission device (2) and the second drive motor (3.5) of the lower transmission device (3) respectively drive the front conveyor belt of the upper transmission belt (2.1) and the rear conveyor belt of the lower transmission belt (3.1) to move in opposite directions, so that the upper positioning clamp (2.2.2) and the lower positioning clamp (3.2.2) at the end are staggered and moved a certain distance, so that the ends of different upper and lower rods are staggered and correspond to each other. After the arrangement is ready, a gasket is manually placed at the annular spring clamp (3.2.4); Step 5: Start the assembly mechanism (4), the screw lifting mechanism (4.2.1) moves the upper transmission device (2) downward as a whole, the rod is pressed accordingly, the screw feeding mechanism (4.3) places the screw on the slide rail of the screw tightening device, the moving truss (4.2) moves the screw locking mechanism (4.1) to the limit hole (2.2.3) of the corresponding upper rod positioning clamp (2.2), and the cylinder drives the screw to move to the limit bar hole (4.1.4) to tighten the screw; Step 6. After the corresponding screws are tightened, the screw lifting mechanism ( 4.2.1) drives the entire upper transmission device (2) to rise, pushes out the finished product through the extraction mechanism (4.4), and the fixture automatically resets and moves to the corresponding area for the next loading.
