[0044] The front inner side of the equipment rack 1 is provided with a mounting plate 12 located above the recovery drawer 13, and the mounting plate 12 is provided with four sets of infrared distance measuring probes 21 (the model of the infrared distance measuring probes 21 is MLX90621), a coolant recovery slot 20 and a straight coolant injection nozzle 19 in sequence from front to back;

[0045] Molybdenum wire height adjustment components 6 are fixed on both sides of the equipment frame 1, and a molybdenum wire 28 located at the rear of the straight strip coolant injection nozzle 19 is connected between the molybdenum wire heads 66 on the two groups of molybdenum wire height adjustment components 6;

[0046] The molybdenum wire height adjustment assembly 6 includes a support 63 fixed on the side of the equipment frame 1, a vertical guide rail 62 fixed inside the support 63, a lifting seat 61 sliding on the vertical guide rail 62, and an adjustment motor 64 installed at the bottom of the support 63. The top output end of the adjustment motor 64 is provided with a screw rod 65 extending into the support 63, and the screw rod 65 passes through the lifting seat 61. The adjustment motor 64 drives the lifting seat 61 to move up and down through the screw rod 65, and the molybdenum wire head 66 is fixed on the lifting seat 61.

[0047] Both groups of regulating motors 64 are servo motors, and the two groups of regulating motors 64 work synchronously under the control of the PLC controller.

[0048] After the 3D printed substrate 9 is turned down 180°, the infrared distance measuring probe 21 is used to detect the height of the 3D printed substrate 9, and the molybdenum wire height adjustment assembly 6 is used to adjust the height of the molybdenum wire 28, so that when the 3D printed substrate 9 moves backward, the molybdenum wire 28 cuts the 3D printed part 8 on the 3D printed substrate 9;

[0049] When the molybdenum wire 28 cuts the 3D printed part 8, the straight strip coolant spray nozzle 19 is used to spray coolant onto the 3D printed part 8, a portion of the coolant falls to the first recovery tank 23 at the front of the recovery drawer 13 through the coolant recovery groove 20, and another portion of the coolant and the cut 3D printed part 8 fall to the second recovery tank 25 at the rear of the recovery drawer 13;

[0050] After the 3D printing substrate 9 is flipped upward 180° and reset, the flipping mechanism moves the 3D printing substrate 9 backward, so that the grinding mechanism at the upper rear end of the equipment frame 1 grinds the portion of the 3D printed part 8 remaining on the 3D printing substrate 9 .

[0051] The side of the equipment frame 1 is provided with a coolant inlet 7 connected to a straight strip coolant injection nozzle 19, the coolant inlet 7 is connected to a coolant pipe, the other end of the coolant pipe is connected to the outlet of the coolant pump, the coolant pump works under the control of the PLC controller, the coolant is introduced into the straight strip coolant injection nozzle 19 through the coolant pipe, and finally sprayed upward through the straight strip coolant injection nozzle 19;

[0052] The side of the equipment frame 1 is provided with a through slot 18 for passing the molybdenum wire 28; the through slot 18 is arranged in a vertical strip shape to meet the requirements of the molybdenum wire 28 moving up and down to adjust the height.

[0053] The inside of the recovery drawer 13 is formed with a first recovery groove 23 and a second recovery groove 25 distributed front and back by an L-shaped partition 24. A rectangular hole 27 is also provided around the horizontal part of the L-shaped partition 24 to achieve the connection between the second recovery groove 25 and the first recovery groove 23 for coolant recovery.

[0054] A soft silicone pad 26 protruding upward is provided in the center of the upper end of the horizontal portion of the L-shaped partition 24 to prevent the 3D printed part 8 from falling and bumping. Rectangular holes 27 are distributed around the bottom of the soft silicone pad 26 .

[0055] The grinding mechanism includes a grinding base 3 fixed in the middle of the upper rear end of the equipment frame 1, a bracket 4 fixed on the side of the rear of the equipment frame 1, a horizontal arm 29 fixed on the bracket 4, and a grinding head 5 installed on the horizontal arm 29. The grinding head 5 is located above the grinding base 3, and a grinding motor (the grinding motor is a servo motor) is installed inside the horizontal arm 29. The output end of the grinding motor passes through the horizontal arm 29 and is fixed to the middle of the rear end of the grinding head 5.

[0056] The present invention also provides a method for using an integrated device for post-processing cutting and flattening of an additively manufactured substrate, which specifically comprises the following steps:

[0057] S1, after the 3D printed substrate 9 is turned down 180°, the infrared ranging probe 21 detects the height of the 3D printed substrate 9, the molybdenum wire height adjustment assembly 6 adjusts the height of the molybdenum wire 28, the 3D printed substrate 9 moves backward, and the molybdenum wire 28 cuts the 3D printed part 8 on the 3D printed substrate 9;

[0058] S2, when the molybdenum wire 28 cuts the 3D printed part 8, the straight strip coolant spray nozzle 19 sprays coolant to the 3D printed part 8, at this time, a part of the coolant falls to the first recovery tank 23 through the coolant recovery groove 20, and the other part of the coolant and the cut 3D printed part 8 fall to the second recovery tank 25 at the rear of the recovery drawer 13;

[0059] S3, the 3D printed substrate 9 is flipped upward 180° and reset, the flipping mechanism moves the 3D printed substrate 9 backward, and the grinding mechanism at the upper rear end of the equipment frame 1 grinds the portion of the 3D printed part 8 remaining on the 3D printed substrate 9, and the remaining portion of the 3D printed part 8 is ground flat.

[0060] Specifically, when in use, the PLC controller controls the two groups of flip motors 11 to work synchronously, so that the flip motor 11 drives the flip plate 10 to rotate 180° clockwise through the vertical plate 16, so that the 3D printing substrate 9 on the flip plate 10 is inverted;

[0061] At this time, the four sets of infrared distance measuring probes 21 detect the distance between them and the inverted 3D printing substrate 9. Once the height of the 3D printing substrate 9 is too low, the PLC controller controls the adjustment motor 64 to work, so that the screw rod 65 rotates clockwise to drive the lifting seat 61 to move down, until the height of the molybdenum wire 28 is reduced to an appropriate position, that is, the molybdenum wire 28 is reduced to a height that can completely cut the 3D printing part 8 when the molybdenum wire 28 cuts the 3D printing part 8;

[0062] Once the height of the 3D printing substrate 9 is too high, the PLC controller controls the adjustment motor 64 to work, so that the lead screw 65 rotates counterclockwise to drive the lifting seat 61 to move up, until the height of the molybdenum wire 28 rises to an appropriate position, that is, the molybdenum wire 28 rises to a height that can completely cut the 3D printing part 8 when the molybdenum wire 28 cuts the 3D printing part 8;

[0063] Since the mounting frame 15 is provided with a slide seat 14 at the bottom thereof, and the slide seat 14 is slidably connected to the corresponding slide rail 2, the mounting frame 15 moves backward along the slide rail 2, so that the inverted 3D printing substrate 9 moves backward, and the 3D printing part 8 on the 3D printing substrate 9 gradually approaches the molybdenum wire 28 until the molybdenum wire 28 completely cuts the 3D printing part 8 off the 3D printing substrate 9;

[0064] When the 3D printed part 8 is cut, the coolant pump works under the control of the PLC controller, introduces the coolant into the straight strip coolant injection nozzle 19 through the coolant pipe, and finally sprays the coolant upward to the 3D printed part 8 through the straight strip coolant injection nozzle 19, so as to cool down the molybdenum wire 28 when cutting the 3D printed part 8;

[0065] At this time, when the coolant is sprayed upward through the straight coolant spray nozzle 19, the coolant will be blocked by the 3D printing substrate 9 and the coolant will fall. A part of the coolant will fall to the first recovery tank 23 at the front of the recovery drawer 13 through the coolant recovery groove 20, and the other part of the coolant will fall to the second recovery tank 25 at the rear of the recovery drawer 13, and finally converge in the first recovery tank 23 through the rectangular hole 27; such a setting prevents the coolant from gathering inside the second recovery tank 25, realizes the separation and recovery of the 3D printed part 8 and the coolant, and the 3D printed part 8 is immersed in the coolant;

[0066] The cut 3D printed part 8 falls onto the upwardly protruding soft silicone pad 26 inside the second recycling tank 25. The soft silicone pad 26 prevents the 3D printed part 8 from falling and bumping. After the recycling drawer 13 recycles the coolant and the 3D printed part 8, the recycling drawer 13 is pulled out to take out the cut 3D printed part 8.

[0067] Subsequently, the PLC controller controls the two groups of flip motors 11 to work synchronously, so that the flip motor 11 drives the flip plate 10 to rotate 180° counterclockwise to reset through the vertical plate 16, and the PLC controller controls the grinding motor to work, so that the grinding motor drives the grinding head 5 to rotate;

[0068] As the mounting frame 15 continues to move backward along the slide rail 2, the remaining portion of the upper surface of the 3D printing substrate 9 contacts the grinding head, so that the grinding head grinds the portion remaining on the 3D printing substrate 9 after the 3D printed part 8 is completely cut.

[0069] The present invention cuts the connection between the 3D printed part 8 and the 3D printed substrate 9 by horizontal line cutting. After the cutting is completed, the 3D printed part 8 is taken out, and the 3D printed substrate 9 is not disassembled and directly enters under the grinding head 5 to start grinding. The present invention can perform continuous operation in an assembly line manner, effectively reducing the manual operation steps in the post-processing process and improving production efficiency.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
