[0047] In summary, when the overall equipment is in use:

[0048] When it is necessary to drill holes for anti-theft eyes on the door panel, the door panel that needs to be drilled for anti-theft eyes is placed on the operating table 1. A positioning strip is provided on the operating table 1. One side of the door panel is contacted with the positioning strip. At the same time, the two second cylinders 12 are started. The second cylinder 12 drives the fixing plate 13 to move along the sliding connection with the operating table 1. With the cooperation of the two fixing plates 13, the door panel is fixed to the operating table 1. The first cylinder 3 is started. The first cylinder 3 drives the lifting frame 4 to move downward. The lifting frame 4 drives the limiting plate 8, the lifting rod 7 and the pressing seat 9 to move downward, so that multiple pressing seats 9 are in contact with the upper end of the door panel. As the lifting frame 4 continues to move downward, the first spring 10 is compressed, and multiple pressing seats 9 press the door panel. At the same time, the lifting frame 4 drives the first motor 5 and the drill bit 6 to move downward. The first motor 5 is started. The first motor 5 drives the drill bit 6 to rotate to drill holes for anti-theft eyes on the door panel. The shielding cover 11 shields the waste generated during the drilling process to prevent splashing.

[0049] When it is necessary to clean the waste chips generated during the drilling process of the door panel, during the drilling process, the shielding cover 11 shields the waste chips to prevent them from splashing. When the drilling is completed, some of the waste chips will enter the collection box 23 through the through hole 22 for collection. The first cylinder 3 is started to move the lifting frame 4 and the drill bit 6 back to their original positions. The second motor 19 is started, and the second motor 19 drives the rotating gear 18 to rotate. The rotating gear 18 drives the sleeve 14 to rotate through the gear ring 17. Since the sleeve 14 is threadedly connected to the screw 15, the screw 15 drives the cleaning brush 16 to move, thereby brushing and cleaning the door panel. The cleaning brush 16 drives the two limit rods 20 to move and limit the cleaning brush 16. The limit rod 20 drives the moving plate 21 to move and limit the limit rod 20. The waste chips cleaned by the cleaning brush 16 will enter the collection box 23 from one side of the operating table 1, and the baffle 24 blocks the waste chips.

[0050] When the door panel needs to be removed, the two second cylinders 12 are started to separate the fixing plate 13 from the door panel, and the third motor 32 is started. The third motor 32 drives the driving gear 31 to rotate, and the driving gear 31 drives the two driven gears 30 to rotate at the same time. The driven gear 30 drives the rotating rod 28 to rotate, and the rotating rod 28 drives the convex column 29 to rotate. When the protruding part of the convex column 29 contacts the ejection frame 26, the ejection frame 26 is pushed upward as the convex column 29 rotates. The ejection frame 26 moves upward and pushes the door panel, so that the door panel is separated from the operating table 1, and the second spring 27 is stretched, which makes it convenient for the staff to remove the door panel.
