[0047] When in use, several electric energy meters are clamped between the flexible pressure strips 25 and move forward with the operation of the conveyor belt 22. When the electric energy meters move to the drilling station, the high-speed spindle motor 1 is controlled by the Y-axis electric slide 5 and the X-axis electric slide 7 to move to the corresponding position above the electric energy meters. The high-speed spindle motor 1 is controlled by the Z-axis electric slide 6 to move downward. The high-speed spindle motor 1 controls the drill bit 2 to rotate to drill the electric energy meters. The waste chips generated by drilling are sucked by the waste chip collection box 3 and the slag suction pipe 4 and collected in the total waste chip box. Some of the waste chips remaining on the electric energy meters can enter the waste chip collection box 26 below through the chip falling area.

[0048] The waste collection box 26 is slidably fitted on the conveying frame 21. The conveying frame 21 includes 4 pillars, a bottom plate is provided between the pillars on the left and right sides, baffles are provided on both sides of the bottom plate, and the inner wall of the baffle has a movable groove. The outer side of the waste collection box 26 has a limiting protrusion or a sliding wheel, so that the waste collection box 26 can be slidably fitted on the conveying frame 21, so as to facilitate the collection of fallen waste from various positions.

[0049] In addition, if Fig. 9 As shown, the waste collection box 26 has a collection port 26-1 and a collection area 1 26-2, and the collection port 26-1 has a certain curvature or inclined structure to facilitate the waste to enter the collection area 1 26-2.

A fan 26-6 is provided on one side of the collecting area 26-3, and the fan 26-6 blows air at least toward one inner wall surface, and can also rotate to blow the waste chips toward the electromagnetic adsorption plate 26-5, so that the iron filings and impurities such as plastic waste or dust are separated. After a period of time, the waste chip collection box 26 can be opened to remove the electromagnetic adsorption plate 26-5, and the plastic waste or dust and other impurities in the collecting area 2 26-3 can be poured out; in addition, in order to form air convection, the surface of the collecting area 2 26-3 also has an air outlet.

[0050] In addition, if Fig.10 As shown, the high-speed spindle motor 1 is arranged on the Z-axis electric slide 6 through a high-speed motor mounting plate 27, and a connecting plate 28 is provided on the surface of the high-speed motor mounting plate 27, and the high-speed motor mounting plate 27 and the connecting plate 28 can be vertically connected; a connecting rod 1 29 is provided on the connecting plate 28, one end of the connecting rod 1 29 is hinged to a connecting rod 2 30, one end of the connecting rod 2 30 is hinged to the frame of the punching device, the other end of the connecting rod 2 30 is hinged to a connecting rod 3 31, one end of the connecting rod 31 is hinged to an L-shaped rod 32, and the L-shaped rod 32 is hinged to the front end of the waste chip collection box 26; Fig.10Take the example shown for explanation. After drilling is completed, when the Z-axis electric slide 6 drives the high-speed spindle motor 1 to move upward, the connecting rod 1 29 follows the connecting plate 28 to move upward, causing the connecting rod 2 30 to have a tendency to move upward. Since the upper end of the connecting rod 2 30 is hinged on the frame of the punching device, the connecting rod 2 30 will rotate clockwise around the hinge point, thereby driving the connecting rod 3 31 to move toward the upper left, and finally driving the waste chip collection box 26 to move toward the left side through the L-shaped rod 32, that is, the connecting rod 1 29 drives the connecting rod 2 30 to rotate, thereby driving the waste chip collection box 26 toward the moving direction of the electric energy meter through the connecting rod 3 31 and the L-shaped rod 32. In summary, after drilling is completed, the conveyor belt 22 drives the electric energy meter with the drilling completed to move to the left, and the Z-axis electric slide 6 drives the high-speed spindle motor 1 to move upward, and at the same time drives the waste collection box 26 to move toward the left side along with the electric energy meter with the drilling completed through the connecting rod 1 29, the connecting rod 2 30, the connecting rod 3 31 and the L-shaped rod 32, so as to collect the waste chips dropped from the electric energy meter. In addition, the speed of the conveyor belt 22 can be set to be variable, that is, it has a certain acceleration, and this acceleration can be positive or negative, so that the waste chips on the electric energy meter can move relative to each other due to inertia and fall into the waste collection box 26. In order to facilitate the falling of the waste chips on the electric energy meter with the drilling completed, a fan can also be provided on the conveyor frame, and the angle of the fan can be toward the waste collection box 26. When the next electric energy meter moves to the drilling station, the Z-axis electric slide 6 drives the high-speed spindle motor 1 to move downward, and drives the waste collection box 26 back to the bottom of the electric energy meter to be drilled through connecting rod 1 29, connecting rod 2 30, connecting rod 3 31 and L-shaped rod 32 to collect waste chips.
