Description

Technical Field

[0001] The invention relates to the technical field of chip removal of a milling machine, and in particular to an automatic chip removal device of a PCB milling machine with a dust cover. Background Art

[0002] The edge milling machine is a device that uses the high-speed rotation of the cutter disc to achieve the purpose of milling the plate. It is specially used to mill and grind the ends of the plate to ensure that the ends of the plate are flat and smooth, and to ensure that the plate will not cut the workers during assembly.

[0003] Since the milling machine will generate a lot of debris during operation, it is necessary to clean the generated debris. During the milling process, the debris is easy to adhere between the milling machine and the workpiece to be milled. Therefore, exhaust pipes need to be installed on the upper and lower sides of the workpiece to be milled, and the gas discharged from the exhaust pipes can be used to blow away the adhering debris.

[0004] Since the milling machine needs to continuously deflect up and down during the milling process, the size of the upper and lower areas of the workpiece to be milled will change at any time, which will cause the adhered debris to not be blown away in time or the blowing force is too strong, causing the debris to fly everywhere.

DETAILED DESCRIPTION

[0026] See also Figures 1 to 6 The present invention provides a technical solution: an automatic chip removal device for a PCB milling machine 2 with a dust cover, comprising a dust cover body 1, a milling machine 2 installed at a corner on one side of the dust cover body 1, a storage table 10 installed on the side of the dust cover body 1 away from the milling, a deflection ring 13 is rotatably connected to the annular surface of the coupling of the milling machine 2, a deflection plate 4 is installed on the annular surface of the deflection ring 13, a circular hole 16 is opened on the side of the deflection plate 4 away from the deflection ring 13, the milling machine 2 is arranged in the circular hole 16, and the deflection ring 13 is provided with a circular hole 16. Deflection holes 15 are provided at both ends of the plate 4, and a deflection rod 5 is rotatably connected to the deflection hole 15. The end of the deflection rod 5 away from the deflection plate 4 is installed in the dust cover body 1. When the milling machine 2 is milling the PCB board normally, the deflection plate 4 will not contact the milling machine 2. When the milling machine 2 needs to mill the PCB board at different angles, the angle of the milling machine 2 changes, which in turn drives the angle of the deflection ring 13 to change. The change in the angle of the deflection ring 13 drives the angle of the deflection plate 4 to change.

[0027] A dust collector is provided on the outside of the dust cover body 1, and the air inlet end and exhaust end of the dust collector are respectively installed with an air inlet pipe 8 and an exhaust pipe 6. The air inlet pipe 8 and the exhaust pipe 6 both extend into the dust cover body 1, and the deflector plate 4 is provided with a movable groove 11 on the upper and lower sides. A movable block 14 is slidably connected in the movable groove 11, and a sealing plate 3 is installed on the side of the movable block 14 away from the slide groove 28. The end of the exhaust pipe 6 away from the dust cleaner is in contact with the sealing plate 3 and the storage table 10, and the sealing plate 3 facing the exhaust pipe 6 is provided with an arc groove 17, and a rotating ring 12 is rotatably connected in the arc groove 17. The rotating ring 12 is connected to the exhaust pipe 6, and the end of the exhaust pipe 6 away from the vacuum cleaner is in contact with the sealing plate 3 and the storage table 10.

[0028] A deflection structure consisting of a deflection ring 13, a deflection plate 4 and a deflection rod 5 is installed on the annular surface of the coupling of the milling machine 2, and a blocking structure consisting of a blocking plate 3, a rotating ring 12 and a moving block 14 is installed on the deflection structure. The exhaust pipe 6 is divided into multiple exhaust areas by using the blocking structure and the storage table 10. When the milling machine 2 grinds the edge of the PCB board at different angles, the deflection structure rotates along with the deflection of the milling machine 2, and drives the blocking structure to deflect, so that the size of the two areas separated by the exhaust pipe 6 changes, thereby ensuring that when the milling machine 2 grinds the edge of the PCB board at different angles, the amount of gas discharged from the exhaust pipe 6 is sufficient to clean the debris adhered to the milling machine 2 at different angles.

[0029] The end of the air inlet pipe 8 away from the vacuum cleaner is connected to the vertical cylinder 7, and the vertical cylinder 7 is arranged at the lower side of the deflection plate 4 and the storage table 10. A hinged plate 18 is hinged in the vertical cylinder 7, and a slide groove 28 is opened on the lower surface of the hinged plate 18. A slider 27 is slidably connected in the slide groove 28. An L-shaped rod 29 is installed on the side of the slider 27 facing the outside of the slide groove 28. A filter screen 21 is installed at the end of the L-shaped rod 29 away from the slider 27. The filter screen 21 slides in contact with the hinged plate 18, and the end of the filter screen 21 away from the hinged plate 18 slides in contact with the vertical cylinder 7. A rotating rod 19 is provided in the vertical cylinder 7 for horizontal rotation and connection in the vertical cylinder 7. A plurality of rotating plates 20 arranged in an annular manner are installed on the annular surface of the rotating rod 19. The rotating plate 20 rotates in contact with the lower surface of the hinged plate 18. A collecting cylinder 9 is then installed on the outside of the vertical cylinder 7. The collecting cylinder 9 is arranged at the filter screen 21, and the collecting cylinder 9 is used to collect the debris intercepted on the filter screen 21.

[0030] By installing a filtering structure consisting of a hinged plate 18, a filter screen 21, a slider 27 and an L-shaped rod 29 in the vertical cylinder 7, and then contacting the filtering structure with a lifting structure consisting of a rotating rod 19 and a rotating plate 20, the lifting structure is used to increase the inclination angle of the filtering structure, thereby facilitating the debris filtered by the filtering structure to enter the collection cylinder 9.

[0031] A support plate 26 installed in the vertical cylinder 7 is provided on the upper side of the filter screen, and a cylinder 24 is installed on the lower surface of the support plate 26. A round rod 23 is inserted into the cylinder 24, and a knocking ball 22 is installed at the end of the round rod 23 away from the cylinder 24. An elastic member is installed at one end of the round rod 23 in the cylinder 24. The elastic member is a spring. When the elastic member is in a normal state, the function of the elastic member is to accelerate the reset of the knocking ball 22. The end of the elastic member away from the round rod 23 is installed in the cylinder 24.

[0032] A knocking structure consisting of a support plate 26, a cylinder 24, a round rod 23 and a knocking ball 22 is installed above the filter structure. The knocking structure is in contact with the filter structure to facilitate cleaning of debris on the surface of the filter structure.

[0033] A support rod 25 is hinged on the upper surface of the filter screen 21, and a circular hole 16 is opened on the lower surface of the support plate 26. The support rod 25 is inserted into the circular hole 16. The support rod 25 is used to ensure that the filter screen 21 maintains contact with the inner wall of the vertical cylinder 7 when moving on the inner wall of the vertical cylinder 7, thereby preventing debris entering the vertical cylinder 7 from entering the air intake pipe 8.

[0034] In summary, when using the automatic chip removal device of the PCB milling machine 2 with a dust cover, first place the PCB board to be milled on the workbench, then start the milling machine 2 to mill the PCB board, and start the vacuum cleaner while milling. After the vacuum cleaner is started, the debris generated by the milling machine 2 when milling the PCB board will be sucked into the vertical cylinder 7 by the air inlet pipe 8. When the air passes through the vertical cylinder 7, it drives the rotating plate 20 to rotate. The rotating plate 20 rotates and continuously contacts the hinge plate 18, and squeezes the hinge plate 1 8, so that the hinged plate 18 tilts upward, and at the same time drives the filter screen 21 to tilt upward. Since the filter screen 21 is restricted by the support rod 25, the filter screen 21 always keeps in contact with the inner wall of the vertical cylinder 7 when tilting upward. At the same time, the slider 27 is moved in the slide groove 28 to ensure that the hinged plate 18 and the filter screen 21 keep in contact. When the debris is intercepted by the filter screen 21, the debris intercepted on the filter screen 21 flows along the filter screen 21 and the hinged plate 18 into the collection cylinder 9 to collect the debris generated during the milling process.

[0035] The air entering the vacuum cleaner is then discharged from the exhaust pipe 6. Since part of the exhaust pipe 6 is blocked by the blocking plate 3 and the storage table 10, the air in the exhaust pipe 6 can only be discharged through the unblocked area, thereby cleaning the debris adhered to the milling machine 2. When the edge of the PCB board is milled at different angles, the deflection plate 4 changes its angle along with the milling machine 2, thereby also driving the blocking plate to change the area blocked by the exhaust pipe 6, so that the area where the gas is discharged from the exhaust pipe 6 changes as the milling angle of the PCB board edge changes. The amount of gas discharged from the exhaust pipe 6 is sufficient to clean the debris adhered to the milling machine 2 at different angles.
