When the positioning platform 31 reaches a preset position, the seventh driving device stops running. At this time, the vertical distance between the running track of the cut-to-length script body 3211 and the running track of the head-end script body 2111 is the preset length of the door cover 5; Step 3) placing the door cover 5 on the workbench 111 and the mobile platform 31, so that the slot 51 on the bottom surface of the door cover is aligned with the first clamping position 112 and the second clamping position 311, and the inner edge of the slot 51 is aligned with the inner edge of the first clamping position 112 and the second clamping position 311, and adjusting the door cover 5 so that the first edge of the second direction is close to the pressing block of the double-rod cylinder positioning assembly 411; Step 4) Simultaneously start the pressing device 42 to press and fix the door cover 5 on the workbench 111 and the positioning platform 31; Step 5) The end trimming device 21 and the cut-to-size device 32 are turned on, and the piston rod of the positioning device 41 is retracted and reset, so as to complete the end trimming and cut-to-size cutting of the door cover 5; after completing the above operations, the end trimming device 21 and the cut-to-size device 32 are lifted upward, so that the cutting tool is away from the door cover 5, and are reset horizontally to the origin along the first direction; Step 6) The slotting device is turned on, and the slotting script body 2211 and the marking script body 2221 are moved along the first direction of the operating table 11 to perform slotting and fine cutting operations on the bottom surface of the door cover 5. After the above work is completed, the slotting script body 2211 and the marking script body 2221 are horizontally reset to the origin along the first direction; Step 7) Start the clamping device 42 to retract its piston rod and release the pressure and fixation on the door cover 5; Step 8) Open the single-rod cylinder positioning assembly 412 of the positioning device 41, and extend its piston rod. When it reaches its maximum stroke, the pressure block at the end of the piston rod pushes the door cover 5 out in the second direction, and the door cover is removed; Step 9) starting the seventh driving device 315 of the mobile platform 31 to make it rotate in the opposite direction, so that the mobile platform returns horizontally to the origin along the second direction; Step 10) Repeat the above steps 1)-9) to carry out the next round of operation.
