[0030] A dust removal module is also provided in the box body: 1, and the dust removal module includes a dust removal box 5, an operation box 6, an extraction device for sucking dust, and a judgment device for whether the inner wall of the dust removal box 5 needs to be cleaned. The operation box 6 is fixedly connected to the top of the dust removal box 5, and the extraction device adopts a vacuum cleaner of the prior art. The vacuum cleaner extracts the dust in the dust removal box 5, and then the dust or debris generated during the grinding or milling process can be sucked away; the judgment device includes a detection mechanism for judging whether dust is adhered to the inner wall of the dust removal box 5 and an air curtain mechanism for blocking the opening of the operation box 6. The detection mechanism is used to detect and judge whether dust is adhered to the inner wall of the dust removal box 5, and the air curtain mechanism is used to isolate the dust removal box 5 and the operation box 6 to prevent dust from entering the operation box 6.

[0031] The detection mechanism includes a detection frame 7 which is lifted and arranged in the dust removal box 5, a rubber block 8 which is movably arranged on the detection frame 7, an identification component for identifying whether dust is adhered to the rubber block 8, a driving component for controlling the movement of the rubber block 8 on the detection frame 7, and a friction component for cleaning the dust on the rubber block 8; the detection frame 7 moves along the depth direction of the dust removal box 5, and the rubber block 8 moves along the length and width directions of the dust removal box 5. The detection frame 7 is lifted and arranged in the dust removal box 5, and the detection frame 7 is located in the operation box 6 in the initial position. After the rubber block 8 contacts the inner wall of the dust removal box 5, part of the dust adheres to the rubber block 8, and the identification component is used to identify whether dust is adhered to the rubber block 8. If dust is adhered, the inner wall of the dust removal box 5 needs to be cleaned.

[0032] The driving assembly includes a first adjusting part that enables the rubber block 8 to move along the length direction of the dust removal box 5 and a second adjusting part that enables the rubber block 8 to move along the width direction of the dust removal box 5. The second adjusting part includes a second electric push rod 9 and an adjusting frame 10. The adjusting frame 10 moves along the width direction of the dust removal box 5. The second electric push rod 9 controls the movement of the adjusting frame 10. In this embodiment, the rubber block 8 does not contact the inner wall of the dust removal box 5 in the initial position. Therefore, it is necessary to control the rubber block 8 to move along the width direction of the dust removal box 5 through the second adjusting part, so that it can contact the side wall of the dust removal box 5 in the length direction. Of course, in this embodiment, both side walls of the dust removal box 5 in the length direction need to be contacted. In order to make the judgment more accurate, the first adjusting part controls the rubber block 8 to move along the length direction of the detection frame 7, that is, it moves along the length direction of the dust removal box 5. Therefore, the rubber block 8 can detect the side wall of the dust removal box 5 along the length direction to improve the accuracy of the judgment. The second electric push rod 9 is fixed on the detection frame 7, and the adjusting frame 10 slides on the detection frame 7.

[0033] The adjusting frame 10 is provided with an adjusting hole 12, and a plug rod 11 is inserted into the adjusting hole 12 of the adjusting frame 10. A disc 13 is fixedly connected to the end of the plug rod 11, and the disc 13 clamps the rubber block 8 on the adjusting frame 10. A protrusion 14 is fixedly connected to the side wall of the plug rod 11. A slide groove 15 is provided on the inner wall of the adjusting hole 12. An arc groove 16 is provided on the end side wall of the slide groove 15 of the adjusting hole 12. The protrusion 14 slides along the slide groove 15 into the arc groove 16. The rubber block 8 is also provided with a perforation correspondingly. The rubber block 8 is placed on the adjusting frame 10, and the adjustment hole 12 is connected with the through hole, the plug rod 11 passes through the rubber block 8 and is plugged into the plug hole. At this time, the disc 13 abuts against the rubber block 8 and squeezes the rubber block 8 on the adjustment frame 10, and at the same time, the protrusion 14 moves along the slide groove 15 to the opening of the arc groove 16, and the rotation of the plug rod 11 is controlled. The protrusion 14 slides from the slide groove 15 into the arc groove 16. At this time, the movement of the protrusion 14 along the length direction of the plug hole is restricted, and the plug rod 11 is fixed on the adjustment frame 10, thereby completing the locking effect of the rubber block 8.

[0034] The first adjustment part includes two guide rails 17, a slide bar 18 and a slide plate 19. In this embodiment, the adjustment frame 10 is preferably fixed on the slide plate 19. Both ends of the two guide rails 17 are externally connected to a power source, and the two ends of the guide rails 17 are respectively connected to the positive and negative poles of the two external power sources. The two ends of the slide bar 18 are respectively sleeved and slid on the two guide rails 17. The slide bar 18 is fixedly connected to the slide plate 19. The guide rails 17 and the slide bar 18 are made of conductive materials. The two guide rails 17 are externally connected to power sources with opposite positive and negative poles. In this embodiment, the positive and negative power sources are respectively connected to the same end of the two guide rails 17, and then another positive and negative power source is connected to the other end of the guide rails 17, and the two ends of the same guide rail 17 are respectively connected to power sources with different electrodes, so that the slide bar 18 can reciprocate. When the slide plate 19 needs to move, an electric Source, so that the power flows on the two guide rails 17 and the slide bar 18, the two guide rails 17, the slide bar 18 and the external DC power supply form a closed loop, according to the direction of current flow and Ampere's law, the direction of the magnetic flux lines of the two guide rails 17 and the slide bar 18 close to the energized power supply side can be obtained, and then the left-hand rule can be used to obtain that the direction of the Ampere force on the slide bar 18 is parallel to the guide rail 17 and along the length direction of the detection frame 7, that is, when the guide rail 17 is energized, the slide bar 18 is acted upon by the Ampere force and moves on the guide rail 17 along the length direction of the detection frame 7, thereby driving the slide plate 19 to move, and when the rubber block 8 needs to move in the opposite direction, this power supply can be turned off and another power supply can be turned on, at this time, the movement direction of the slide bar 18 moves in the opposite direction, and then the adjustment frame 10 can be controlled to move along the length direction of the detection frame 7.

[0035] When the rubber block 8 is in friction with the side wall of the dust removal box 5, the rubber block 8 is adhered to the side wall of the dust removal box 5. At this time, the detection frame 7 is controlled to move along the depth direction of the dust removal box 5. Dust is adhered to the rubber block 8 during the friction between the rubber block 8 and the side wall of the dust removal box 5. At this time, the rubber block 8 can be pulled to the position of the marking component to mark whether the rubber block 8 is adhered to dust. Then the rubber block 8 is pulled away from the side wall of the dust removal box 5, and the rubber block 8 is controlled by the slide bar 18 to move along the length direction of the detection frame 7, that is, the rubber block 8 can contact other positions of the side wall of the dust removal box 5 in the length direction, and then contact other positions of the side wall of the dust removal box 5. After multiple frictions and markings, the marked position is identified, thereby improving the accuracy of judging whether the dust removal box 5 is adhered to dust. Similarly, the above operation can process the other side wall of the dust removal box 5.

[0036] The marking components are arranged in two groups and are respectively located at the top of the dust removal box 5 and at both sides of the length direction of the rubber block 8. The marking components include marking paper 20, a color sensor 21, a trigger part and a winding part for winding the marking paper 20. The marking paper 20 moves along the length direction of the dust removal box 5. The color sensor 21 is arranged in a transparent box and fixed in the dust removal box 5. The color sensor 21 is facing the marking paper 20. After the end of the rubber block 8 rubs against the marking paper 20, the color of the adhered dust appears on the marking paper 20. The color sensor 21 identifies the color of the dust. This embodiment is described with a side wall of the dust removal box 5 and the corresponding marking components. The winding The part includes two winding motors and two winding rollers. The two ends of the marking paper 20 are fixedly connected to the outer walls of the two winding rollers respectively. The moving direction of the marking paper 20 moves along the length direction of the dust removal box 5. Therefore, the rubber block 8 can be rubbed on different positions on the side wall of the dust removal box 5 in the length direction to mark. The axial direction of the winding roller moves along the length direction of the dust removal box 5. The winding roller is rotatably arranged in the operation box 6. The color sensor 21 is facing the marking paper 20. In this embodiment, the marking paper 20 is made of a material that is convenient for the rubber block 8 to mark, which makes it convenient for the rubber block 8 to leave traces of dust on the marking paper 20, which is recognized by the color sensor 21.

[0037] The triggering part includes a triggering electric push rod 22, a triggering rod 23, an infrared transmitter 25, an infrared receiver 26 and a buzzer 27. The triggering electric push rod 22 is arranged on the outer side of the box body: 1. The triggering electric push rod 22 controls the movement of the triggering rod 23. The infrared transmitter 25 and the infrared receiver 26 are respectively located on both sides of the triggering rod 23 and the infrared rays emitted pass through the triggering hole 24. The triggering rod 23 is provided with a triggering hole 24. The length of the triggering hole 24 is equal to the distance that the triggering electric push rod 22 pushes the triggering rod 23 to move twice, that is, if the color sensor 21 recognizes more than two dust colors, the infrared receiver 26 cannot receive the signal of the infrared transmitter 25. The buzzer 27 is electrically connected to the infrared receiver 26, and the buzzer 27 and the infrared receiver 26 are controlled and connected by the PLC controller; in this embodiment, it is set to the same side wall of the dust removal box 5 Four inspections are required, so each time the eraser block 8 contacts and rubs against the marking paper 20, the mark on the marking paper 20 needs to be pulled to a position away from the eraser block 8, so that there are four marks on the marking paper 20. In the initial state, the infrared signal emitted by the infrared transmitter 25 passes through the trigger hole 24, and when the color sensor 21 recognizes the mark on the marking paper 20, the infrared sensor controls the trigger electric push rod 22 to move, and the trigger electric push rod 22 controls the trigger rod 23 to move. As long as two or more of the four marks have dust and are recognized by the color sensor 21, the trigger rod 23 isolates the infrared transmitter 25 and the infrared receiver 26. After the infrared receiver 26 does not receive the signal from the infrared transmitter 25, the buzzer 27 is triggered to make a sound, which proves that there is dust on the corresponding inner wall of the dust removal box 5 and needs to be cleaned.

[0038] The wind curtain mechanism includes a plurality of blowing nozzles 29 and an air supply assembly 30. The plurality of blowing nozzles 29 are arranged along the length direction of the operation box 6. The blowing nozzles 29 are close to the position of the dust removal box 5. The air supply assembly 30 can adopt a fan in the prior art. Under the action of the plurality of blowing nozzles 29, a wind curtain wall is formed at the position of the operation box 6, so that when the rubber block 8 is marking or performing dust removal work in the dust removal box 5, no dust will enter the operation box 6; the friction assembly includes a friction member 28 arranged in the operation box 6, and the friction member 28 is provided with two and respectively located on the side walls in the length direction of the operation box 6. After the rubber block 8 contacts the friction member 28, reciprocating friction is achieved through the cooperation of the first adjustment part and the second adjustment part. In this embodiment, the friction member 28 is selected as a long strip and its surface is uneven. Because after dust adheres to the rubber block 8, it is necessary to wipe off the position where the dust adheres to the rubber block 8 through repeated friction between the friction member 28 and the rubber block 8, so as to avoid affecting the next detection work.

[0039] The operating box 6 is also provided with a coating component for coating the outer side of the detection frame 7 with dust-proof oil. The coating component includes a sponge ring 31 and an oil supply component 32 for providing dust-proof oil to the sponge ring 31. The inner diameter of the sponge ring 31 is smaller than the size of the detection frame 7. When the detection frame 7 moves to the sponge ring 31, the sponge ring 31 is squeezed and deformed. The oil supply component 32 includes an oil storage tank and a pipeline. A solenoid valve is provided on the pipeline. The pipeline extends into the sponge ring 31. The sponge has a strong adsorption force, so the sponge can adsorb the dust-proof oil in the oil storage tank into it. As the detection frame 7 moves upward, the detection frame 7 squeezes the sponge ring 31, and the dust-proof oil adsorbed in the sponge ring 31 is squeezed and coated on the surface of the detection frame 7, thereby preventing dust from adhering to the surface of the detection frame 7 and affecting the accuracy of judging whether dust is adhered to the inner wall of the dust removal box 5.

[0040] The implementation principle of the workpiece milling and grinding machine of the embodiment of the present application is as follows: under the action of multiple blowing nozzles 29, an air curtain wall is formed at the position of the operation box 6, so that when the rubber block 8 is marking or the dust removal work is performed in the dust removal box 5, no dust will enter the operation box 6; turn on a power supply so that the power flows on the two guide rails 17 and the slide bar 18, and the two guide rails 17, the slide bar 18 and the external DC power supply form a closed loop, and according to the flow direction of the current and Ampere's law, it can be obtained that the two guide rails 17 and the slide bar 18 are close to the energized power supply side range The direction of the magnetic flux lines inside, and then by the left-hand rule, it can be obtained that the direction of the Ampere force on the slide bar 18 is parallel to the guide rail 17 and along the length direction of the detection frame 7, that is, when the guide rail 17 is energized, the slide bar 18 is acted upon by the Ampere force and moves on the guide rail 17 along the length direction of the detection frame 7, thereby driving the slide plate 19 to move. When the rubber block 8 needs to move in the opposite direction, this power supply can be turned off and another power supply can be turned on. At this time, the movement direction of the slide bar 18 moves in the opposite direction, thereby controlling the adjustment frame 10 to move along the length direction of the detection frame 7.

[0041] When the rubber block 8 is in friction with the side wall of the dust removal box 5, the rubber block 8 is adhered to the side wall of the dust removal box 5. At this time, the detection frame 7 is controlled to move along the depth direction of the dust removal box 5. Dust is adhered to the rubber block 8 during the friction between the rubber block 8 and the side wall of the dust removal box 5. At this time, the rubber block 8 can be pulled to the position of the marking component to mark whether the rubber block 8 is adhered to dust. Then the rubber block 8 is pulled away from the side wall of the dust removal box 5, and the rubber block 8 is controlled by the slide bar 18 to move along the length direction of the detection frame 7, that is, the rubber block 8 can contact other positions of the side wall of the dust removal box 5 in the length direction, and then contact other positions of the side wall of the dust removal box 5. After multiple frictions and markings, the marked position is identified, thereby improving the accuracy of judging whether the dust removal box 5 is adhered to dust. Similarly, the above operation can process the other side wall of the dust removal box 5.

[0042] The movement direction of the marking paper 20 moves along the length direction of the dust removal box 5, so the rubber block 8 can be rubbed against different positions on the side wall of the dust removal box 5 in the length direction to mark. Every time the rubber block 8 contacts and rubs with the marking paper 20, it is necessary to pull the mark on the marking paper 20 to a position away from the rubber block 8, so that there are four marks on the marking paper 20. In the initial state, the infrared signal emitted by the infrared transmitter 25 passes through the trigger hole 24, and when the color sensor 21 recognizes the mark on the marking paper 20, the infrared sensor controls the trigger electric push rod 22 to move, and the trigger electric push rod 22 controls the trigger rod 23 to move. As long as two or more of the four marks have dust and are recognized by the color sensor 21, the trigger rod 23 isolates the infrared transmitter 25 and the infrared receiver 26. After the infrared receiver 26 does not receive the signal of the infrared transmitter 25, the buzzer 27 is triggered to make a sound, which proves that there is dust on the corresponding inner wall of the dust removal box 5 and needs to be cleaned.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
