[0031] Working principle: In this embodiment, the present invention also proposes a method for using a milling device for processing aluminum substrate circuit boards, comprising the following steps:

[0032] Step 1, first connect all electrical equipment with wires and power on, start the third servo motor 22, control the second screw 21 to rotate through the third servo motor 22, and then connect the second screw 21 to the moving seat 20 through threading, and connect the moving seat 20 to the moving plate 19. When the second screw 21 rotates, the moving plate 19 is controlled to move. When the moving plate 19 moves toward the rear end, the rear end surface of the moving plate 19 will abut against the push plate 45. When the moving plate 19 continues to move toward the rear end, the push plate 45 is pushed backward, and then the output shaft of the second hydraulic cylinder 44 is pushed toward the rear end, so that the liquid inside the second hydraulic cylinder 44 is pushed out from the rear end, through The two ends of the connecting pipe 43 are respectively connected to the first hydraulic cylinder 41 and the second hydraulic cylinder 44. When the liquid in the second hydraulic cylinder 44 is pushed out, the second hydraulic cylinder 44 is in a compressed state, and the liquid enters the first hydraulic cylinder 41 through the connecting pipe 43, thereby pushing out the output shaft in the first hydraulic cylinder 41, and the two ends of the hinge rod 40 are respectively hinged with the rotating plate 39 and the output shaft of the first hydraulic cylinder 41, and then the front end of the rotating plate 39 is hinged with the positioning plate 11. When the output shaft of the first hydraulic cylinder 41 moves forward, the rear end of the rotating plate 39 is controlled to rise; at this time, the movable plate 19 moves to the rear end of the housing 1, and the rotating plate 39 is tilted;

[0033] Step 2: When the rotating plate 39 is tilted, start the second servo motor 17, control the driving gear 16 to rotate through the second servo motor 17, and then mesh the driving gear 16 with the driven gear 13 for transmission, connect the driven gears 13 on both sides through the rotating shaft 15, and then mesh the driven gear 13 with the first rack 12 for transmission, and connect the positioning plate 11 through the first rack 12. When the driving gear 16 rotates, the positioning plate 11 is controlled to move. When the positioning plate 11 moves to the front end of the casing 1, the door 2 is opened through the handle 6, and then the circuit board is placed on the tilted rotating plate 39. When the circuit board is placed, the third servo motor 22 is started to rotate in the opposite direction, thereby controlling the second screw 21 to rotate in the opposite direction, and then controlling the moving plate 19 to move forward. At this time, the moving plate 19 no longer controls the movement of the push plate 45, and then the output shaft of the second hydraulic cylinder 44 is pushed forward by the spring 46, so that the liquid in the first hydraulic cylinder 41 flows back into the second hydraulic cylinder 44, and then the output shaft of the first hydraulic cylinder 41 is controlled to move toward the rear end, thereby controlling the rear end of the rotating plate 39 to drop to a horizontal state, and then starting the second servo motor 17 to control the positioning plate 11 to move backward to the milling area;

[0034] Step three, when the moving plate 19 moves forward, the milling assembly is controlled to move forward, and then the milling cutter is placed between the three L-shaped clamping blocks 38, and the stepping motor 32 is started, and the transmission gear 33 is controlled to rotate by the stepping motor 32, and then the transmission gear 33 is meshed with the second rack 34 for transmission, and a positioning rod 35 is passed through the inside of the second rack 34. When the transmission gear 33 rotates, the second rack 34 is controlled to move linearly, and the inclined groove on the top surface of the positioning block 36 and the inclined bar on the bottom surface of the moving block 37 are matched, and then the moving block 37 is placed in the movable groove opened in the connecting block 31. When the second rack 34 moves linearly, the multiple L-shaped clamping blocks 38 are controlled to move relative to each other, and when the multiple L-shaped clamping blocks 38 are close to each other, the milling cutter is clamped;

[0035] Step 4, when the milling cutter is installed, the machine door 2 is closed by the handle 6, and the first servo motor 10, the third servo motor 22, the fourth servo motor 29 and the electric push rod 25 are started at the same time. When the first servo motor 10 is started, the first screw 9 is controlled to rotate, and then the frame 7 is controlled to move, thereby controlling the positioning plate 11 to move to both sides, and then the circuit board is controlled to move to both sides; when the third servo motor 22 is started, the moving plate 19 is controlled to move forward and backward, and then the milling assembly is controlled to move forward and backward; when the fourth servo motor 29 is started, the belt 28 is controlled to rotate, and then the spline sleeve 27 is controlled to rotate, and the spline sleeve 27 is meshed with the spline shaft 26 to control the rotation of the spline shaft 26, and then the connecting column 30 is controlled to rotate, thereby controlling the rotation of the milling cutter; when the electric push rod 25 is started, the spline shaft 26 is controlled to rise and fall, and then the milling cutter is controlled to rise and fall, thereby realizing the milling work of the circuit board;

[0036] Step five, when the milling of the circuit board is completed, the movable plate 19 is controlled to move toward the rear end, and the push plate 45 is pushed toward the rear end. Similarly, the rear end of the rotating plate 39 is controlled to rise, and then the second servo motor 17 is started to control the positioning plate 11 to move forward, and then the machine door 2 is opened by the handle 6, the milled circuit board is taken out, and then all electrical equipment is powered off.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
