For convenient operation, the frame 1 is further provided with a wire coil storage bin 3 for storing wire coils used by the stapler 203.

The specific working method comprises the following steps:

put the filter screen 101 of lapping in the filter screen feed bin 5, after the filter screen in the filter screen feed bin 5 used up, can change convenient operation fast.

First, the outer end of the filter 101 in the filter magazine 5 is manually put on the filter rail 701 and moved below the feed roller 702, and the feed roller 702 is driven by a stepping motor. The feeding roller 702 drives the filter screen 101 to reach the screen cutting position, and the screen cutting action is completed by the screen cutting cylinder 703 driving the screen cutting blade 704. When the filter screen 101 moves a predetermined distance, the screen cutting blade 704 cuts the filter screen 101, and the positioning plate 706 positions the filter screen after cutting.

After the first step of cutting is completed, the filter screen 101 forms a rectangular filter screen piece 102, and the length of the rectangular filter screen piece 102 is the perimeter of the filter screen cylinder 103 to be nailed. The screen panel gripper 403 grips one end of the screen panel 102 and the X-axis module 401 and the Y-axis module 402 cooperate to move the screen panel 102 from the screen cutting assembly 7 to the screen winding assembly 6.

When the filter screen piece 102 moves to the screen winding assembly 6, the positioning plate 706 is opened, the filter screen piece clamping jaws 403 take out the filter screen piece 102 at the position of the positioning plate 706, the filter screen piece 102 is transferred below the central shaft 604 by the filter screen running assembly 4, and the filter screen guide plate 601 can guide the filter screen piece 102 in the transferring process, so that the filter screen piece 102 can smoothly enter a gap between the central shaft 604 and the clasping shaft 602. Next, the clasping cylinder 605 drives the clasping shaft 602 to clasp the filter screen sheet 102, and the filter screen sheet 102 becomes the elliptical filter screen cylinder 103 after clasping.

After the filter cylinder 103 is tightened on the central shaft 604, the forward module 201 drives the stapler 203 to extend into the filter cylinder 103 and staple the filter cylinder.

After the nailing is finished, the clasping cylinder 605 contracts to drive the clasping shaft 602 to separate from the central shaft 604; the cylinder 6062 is contracted to reduce the distance between the left and right center shafts 604, and the filter screen cylinder 103 is loosened from the center shafts 604, so that the filter screen cylinder 103 can be taken out easily.

The forward module 201 moves the stapler 203 back to the home position and the stapled filter cartridge 103 is simultaneously removed from the central shaft 604 with the stapler 203, during which the stapler 203 remains stapling the filter cartridge 103. When the screen cartridge 103 is completely disengaged from the central shaft 604, the stitcher 203 releases the screen cartridge 103 and the screen cartridge 103 is released from the stitcher 203, thereby completing the entire stapling process.
