[0023] 3. When the protective cover moves on the door panel, the protective cover moves with the roller, and the roller rolls along the top of the door panel. The roller limits the cutting edge of the door panel to avoid the phenomenon of the cutting edge of the door panel not being able to be limited and warping, thereby ensuring the quality of the door panel cutting. The top of the roller can roll against the surface of the protective cover to avoid a gap between the top of the roller and the protective cover. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] like Figures 1-12As shown, a door panel cutting device includes: a workbench 1, a cutter 18 and a protective cover 8, the side end of the workbench 1 is slidably connected to a mechanical gripper 10, the top of the workbench 1 is fixedly connected to a positioner 2, the bottom end of the positioner 2 is fixedly connected to a positioning plate 3, both ends of the mechanical gripper 10 are slidably connected to guide rails 9 through guide seats 16, the bottom end of the guide rail 9 is fixedly connected to the workbench 1, the side end of the cutter 18 is slidably connected to the workbench 1 through a cutting mover 19, wherein the cutting mover 19 can be controlled to move by an electric push rod in the prior art, the output end of the cutter 18 is fixedly connected to a cutting knife 17, the top of the protective cover 8 is fixedly connected to a collection box 7 through a number of connecting pipes 35, the bottom of the protective cover 8 is fixedly connected to a connecting pad 36 on both sides of the parallel positioning plate 3, and the bottom of the protective cover 8 is fixedly connected to the vertical positioning plate 3 is rotatably connected with rollers 23 on both sides, and the upper and lower ends of the connecting pipe 35 are respectively connected to the inner cavity of the collection box 7 and the protective cover 8. The top of the collection box 7 is fixedly connected to the driving assembly through a buffer assembly, and the side end of the collection box 7 is fixedly connected to the vacuum cleaner 11 through a dust suction pipe 12. The door panel is placed on the workbench 1, and the mechanical gripper 10 clamps the side end of the door panel, and then the guide seat 16 slides along the inner wall of the guide rail 9. The guide seat 16 slides on the top of the workbench 1 with the mechanical gripper 10, so that the mechanical gripper 10 clamps the door panel and moves. A cutting groove is provided on the top of the workbench 1. When the position where the door panel needs to be cut is aligned with the cutting groove, the positioner 2 drives the positioning plate 3 to move vertically downward, and the positioning plate 3 applies vertical downward pressure to the door panel from the top, thereby fixing the two ends of the door panel.

[0040] At this time, the cutter 18 drives the output end to rotate, and the output end rotates with the cutting knife 17, and then the cutting mover 19 slides along the bottom of the workbench 1, and the cutting mover 19 moves with the cutter 18 along the width direction of the workbench 1, and the cutter 18 moves with the cutting knife 17 along the cutting groove. At the same time, the driving component moves with the buffer component, and the buffer component moves with the collection box 7. The collection box 7 moves with several connecting pipes 35, and the connecting pipe 35 moves with the protective cover 8. The protective cover 8 is located on the top of the door panel, and the protective cover 8 covers the top of the cutting knife 17. The speed of the protective cover 8 and the speed of the cutting knife 17 are the same. The speed is the same. When the cutting knife 17 cuts the door panel and produces waste chips, the protective cover 8 can block the waste chips to prevent the waste chips from splashing into the air. At the same time, the vacuum cleaner 11 is running, and the vacuum cleaner 11 absorbs the waste chips in the protective cover 8. The waste chips first flow from the inner cavity of the protective cover 8 into the connecting pipe 35, and then the waste chips enter the collection box 7 from the connecting pipe 35 for collection. When the waste chips flow out of the inner cavity of the collection box 7, they enter the vacuum cleaner 11 through the dust suction pipe 12 for collection. The vacuum cleaner 11 achieves the effect of collecting the waste chips, and the protective cover 8 can seal and block the waste chips, thereby achieving the effect of timely cleaning and collecting the waste chips generated by the cutting of the door panel by the cutting knife 17.

[0041] When the protective cover 8 moves on the door panel, the connecting pads 36 fixed on both sides of the protective cover 8 slide along the top of the door panel. The bottom of the connecting pads 36 is in a wavy arc shape. The connecting pads 36 are plastic. On the one hand, the connecting pads 36 can reduce the contact area with the door panel. On the other hand, the connecting pads 36 can avoid scratches on the surface of the door panel. The connecting pads 36 can seal the gap between the protective cover 8 and the door panel to avoid waste chips flowing out of the gap. It should be noted that when the airflow in the protective cover 8 flows out with waste chips, the air outside the protective cover 8 passes through the cutting grooves opened on the workbench 1 and the cutting edge of the door panel in turn and enters the inner cavity of the protective cover 8, thereby realizing the fluidity of the air in the protective cover 8.

[0042] When the door panel is being cut, there is a lack of limiting function on both sides of the cutting edge of the door panel, and the positioning plate 3 and the mechanical gripper 10 can only fix the two ends of the entire door panel. Therefore, when the cutting knife 17 cuts the door panel, the cutting edge of the door panel will warp up, which will affect the neatness of the cutting edge of the door panel. When the protective cover 8 moves on the door panel, the protective cover 8 moves with the roller 23, and the roller 23 rolls along the top of the door panel. The roller 23 limits the door panel, thereby ensuring the quality of the door panel cutting. Among them, the top of the roller 23 can roll against the surface of the protective cover 8 to avoid a gap between the top of the roller 23 and the protective cover 8.

[0043] In some specific embodiments, the outer wall of the dust suction tube 12 is sleeved with a circular tubular limiting tube 14, the axis of the limiting tube 14 is in an arc shape, and is fixedly connected to the side end of the positioner 2 through the limiting frame 13, and the inner edges of both ends of the limiting tube 14 are provided with rounded corners. The bottom end of the workbench 1 is fixedly connected with a winding assembly, and the winding assembly is located between the limiting tube 14 and the vacuum cleaner 11. The winding assembly includes: a winding shaft 15 and a winder 32, the top end of the winder 32 is fixedly connected to the workbench 1, the side end of the winder 32 is fixedly connected to the winding shaft 15, the side end of the winding shaft 15 is in contact with the workbench 1, and the dust suction tube 12 is wound around the outer surface of the winding shaft 15 On the surface, the dust suction tube 12 reserves enough length, and the dust suction tube 12 is wound on the winding shaft 15 for storage. When the protective cover 8 moves, the collection box 7 pulls the dust suction tube 12 to move. At the same time, the winder 32 of the winding assembly runs, and the winder 32 drives the winding shaft 15 to rotate. The dust suction tube 12 is taken out from the winding shaft 15 in turn. The winding shaft 15 realizes the function of storing and positioning the dust suction tube 12, avoiding the dust suction tube 12 from being entangled together, thereby avoiding the dust suction tube 12 from being stuck and knotted when the collection box 7 pulls the dust suction tube 12, affecting the waste debris from smoothly entering the vacuum cleaner 11 through the dust suction tube 12.

[0044] When the dust suction tube 12 is taken out from the winding shaft 15, the dust suction tube 12 moves through the limiting tube 14. The limiting tube 14 provides a guide for the movement of the dust suction tube 12 to prevent the dust suction tube 12 from getting stuck when in contact with the workbench 1. The shape of the limiting tube 14 ensures that the dust suction tube 12 will not get stuck with the limiting tube 14 when sliding along the inner wall of the limiting tube 14. The rounded corners of the limiting tube 14 prevent the inner edge of the limiting tube 14 from causing wear on the surface of the dust suction tube 12.

[0045] When the protective cover 8 is reset, the winding shaft 15 rotates in the opposite direction, and the winding shaft 15 winds and stores the dust suction tube 12 to prevent the dust suction tube 12 from being tangled.

[0046] In some specific embodiments, the protective cover 8 is fixedly connected to two sets of cleaners 30 at one end away from the positioning plate 3, and the protective cover 8 is fixedly connected to a cleaning assembly at one end away from the dust collector 11. The output end of the cleaner 30 passes through the protective cover 8 and is fixedly connected to a cleaning shaft 21. The cleaning shaft 21 is fixedly connected to a number of elastic cleaning plates 22 at equal distances along the axis. The waste chips generated by the cutting of the door panel will splash onto the surface of the door panel, and the airflow absorbed by the dust collector 11 cannot fully clean the waste chips on the surface of the door panel. When the protective cover 8 moves on the door panel, the cleaner 30 runs and the cleaner 30 drives the output end to rotate, and the output end rotates with the cleaning shaft 21. The cleaning shaft 21 is rotationally connected to the inner wall of the protective cover 8 at the end away from the cleaner 30. The cleaning shaft 21 rotates around the axis of the cleaning shaft 21 with the cleaning plate 22. When the cleaning plate 22 contacts the surface of the door panel, the bottom end of the cleaning plate 22 slides along the surface of the door panel, and the cleaning plate 22 knocks away the waste chips on the surface of the door panel. The waste chips detach from the surface of the door panel and enter the inner cavity of the protective cover 8, so that the airflow takes the waste chips away from the inner cavity of the protective cover 8, avoiding that the waste chips left on the surface of the door panel cannot be fully cleaned.

[0047] In some specific embodiments, a blocking column 20 is provided on the top of the cleaning shaft 21, and both ends of the blocking column 20 are fixedly connected to the inner wall of the protective cover 8. When the cleaning plate 22 knocks the waste chips from the surface of the door panel, the waste chips will rotate with the cleaning plate 22, so that the waste chips will remain on the surface of the cleaning plate 22 and continue to rotate with the cleaning plate 22, resulting in the waste chips in the inner cavity of the protective cover 8 not being fully cleaned. When the cleaning plate 22 rotates to the blocking column 20 with the waste chips, the cleaning plate 22 collides with the blocking column 20, and the cleaning plate 22 collides with the dust left on the cleaning plate 22, so that the waste chips are separated from the surface of the cleaning plate 22 and enter the inner cavity of the protective cover 8, so that the waste chips are discharged from the inner cavity of the protective cover 8 along with the airflow, avoiding the phenomenon of waste chips remaining on the surface of the cleaning plate 22.

[0048] In some specific embodiments, the cleaning assembly includes: a cleaning pad 24, a positioning column 25 and a mounting plate 26. The positioning column 25 is provided with several groups, and the side ends are fixedly connected to the protective cover 8. The positioning column 25 is located inside the mounting plate 26 at the end away from the protective cover 8. The positioning column 25 is sleeved with the cleaning pad 24 at one end between the mounting plate 26 and the protective cover 8. The side end of the protective cover 8 is fixedly connected to a fixing bracket 29 that passes through the top of the mounting plate 26. The fixing bracket 29 is threadedly connected to a nut 27 that abuts against the mounting plate 26 at the end away from the protective cover 8. When the protective cover 8 moves with the cutting knife 17, in order to prevent waste chips from remaining on the surface of the door panel, When the cutting knife 17 has finished cutting the door panel, the cutting knife 17 and the protective cover 8 are reset, and the cleaning component fixed on the side end of the protective cover 8 cleans the surface of the door panel, and the protective cover 8 moves with the cleaning component. The cleaning pad 24 can be made of sponge, and the cleaning pad 24 is soaked with water before use. When the cleaning pad 24 moves with the protective cover 8, the cleaning pad 24 wipes and cleans the waste left on the surface of the door panel. At the same time, the cleaning pad 24 cleans the surface of the positioning plate 3 to avoid waste and dust on the surface of the positioning plate 3. The soaked cleaning pad 24 can better absorb the waste, thereby ensuring the surface cleanliness of the door panel and the positioning plate 3.

[0049] When the cleaning pad 24 has absorbed enough waste, the cleaning pad 24 can be replaced in time, and the nut 27 can be rotated to release the threaded connection between the nut 27 and the fixing frame 29, thereby releasing the effect of the nut 27 on the limit plate 28. Then, the mounting plate 26 can be removed from the positioning column 25. A positioning hole is provided on the mounting plate 26. At the same time, the top of the mounting plate 26 is released from the sleeve connection with the fixing frame 29. When the mounting plate 26 is installed on the positioning column 25, the side end of the positioning column 25 is inserted into the positioning hole, and the mounting plate 26 is removed from the positioning column 25. After the positioning post 25 is removed, the limiting effect of the mounting plate 26 on the cleaning pad 24 is released, and the cleaning pad 24 is removed from the positioning post 25, thereby releasing the effect of the cleaning pad 24 being connected to the positioning post 25, and a new cleaning pad 24 is put on the positioning post 25, and the mounting plate 26 is installed on the positioning post 25, and then the nut 27 is threadedly connected to the fixing bracket 29, thereby achieving the effect of replacing the cleaning pad 24, ensuring that the cleaning pad 24 can clean the door panel and the positioning plate 3 normally.

[0050] When the nut 27 is threadedly connected to the fixing frame 29, the nut 27 and the limiting plate 28 clamp the two ends of the top of the mounting plate 26, thereby preventing the top of the mounting plate 26 from tilting, thereby ensuring the stability of the mounting plate 26.

[0051] In some specific embodiments, the driving assembly includes: a driver 4, a driving shaft 5 and a driving plate 6. The side end of the driver 4 is slidably connected to the positioner 2. The upper and lower ends of the driving shaft 5 are fixedly connected to the driver 4 and the driving plate 6 respectively. The buffer assembly is provided with two groups and is located at both ends of the driving plate 6. The upper and lower ends of the buffer assembly are fixedly connected to the driving plate 6 and the collection box 7 respectively. When the protective cover 8 moves to the top of the door panel, the driver 4 controls the driving shaft 5 to move vertically downward, and the driving shaft 5 moves vertically downward with the driving plate 6. The driving plate 6 squeezes the buffer assembly, and the buffer assembly squeezes the collection box 7. The collection box 7 is connected The connecting pipe 35 squeezes the protective cover 8, thereby ensuring that the protective cover 8 has a vertical downward pressure when it contacts the top of the door panel, thereby ensuring that the connecting pad 36 fixed at the bottom end of the protective cover 8 is fully supported by the door panel, thereby achieving the effect of the connecting pad 36 fully sealing the gap between the protective cover 8 and the door panel, and the outer wall of the roller 23 is sleeved with a plastic sealing gasket, and the protective cover 8 transmits the pressure to the roller 23, thereby ensuring that the roller 23 can be fully supported by the top of the door panel, avoiding the phenomenon that when the door panel generates vibration during cutting and is transmitted to the protective cover 8, there is a gap between the protective cover 8 and the door panel.

[0052] In some specific embodiments, the buffer assembly includes: a buffer column 33, a buffer tube 34 and a spring 37. The top of the buffer column 33 is fixedly connected to the driving plate 6, the bottom of the buffer column 33 is slidably connected to the inner wall of the buffer tube 34, and the bottom end of the buffer tube 34 is fixedly connected to the collection box 7. The spring 37 is arranged in the inner cavity of the buffer tube 34, and the upper and lower ends are fixedly connected to the buffer column 33 and the collection box 7 respectively. The bottom end of the driving plate 6 is fixedly connected to the sensor 31. When the driving plate 6 moves vertically downward, the driving plate 6 moves vertically downward with the buffer column 33, and the buffer column 33 moves along the buffer tube 3 4 inner wall slides vertically downward, the buffer column 33 compresses the spring 37, and the elastic tension generated by the compression of the spring 37 is transmitted to the collection box 7. The collection box 7 transmits the elastic tension of the spring 37 to the protective cover 8 through the connecting pipe 35. When the door panel is cut, it will vibrate, and the vibration will be transmitted to the protective cover 8. The protective cover 8 transmits the vibration to the collection box 7 through the connecting pipe 35. When the collection box 7 transmits the vibration to the buffer assembly, the buffer assembly will buffer the vibration to prevent the vibration from being transmitted to the drive assembly and affecting the operation of the drive assembly.

[0053] Due to the different thicknesses of the door panels, when the drive assembly controls the buffer assembly to move downward, the sensor 31 can detect the height between the drive plate 6 and the collection box 7, thereby ensuring that the spring 37 of the buffer assembly is in a suitable compression state, thereby ensuring that the elastic tension of the spring 37 acts on the collection box 7 in a suitable state, avoiding the elastic tension provided by the spring 37 being too large, resulting in excessive support force of the protective cover 8 on the door panel, causing scratches on the top of the door panel when the protective cover 8 moves on the top of the door panel.

[0054] In some specific embodiments, the inner wall of the buffer tube 34 is symmetrically provided with a limiting groove 38 along the axial section, and the two ends of the bottom of the buffer column 33 are fixed with a supporting plate 39 that is slidably connected to the inner wall of the limiting groove 38. When the protective cover 8 is moved out from the door panel, the driving assembly controls the buffer column 33 to move vertically upward, and the buffer column 33 slides along the inner wall of the limiting groove 38 with the supporting plate 39. When the supporting plate 39 and the top of the inner wall of the limiting groove 38 are in abutment, the supporting plate 39 and the buffer tube 34 are in abutment. When the buffer column 33 continues to move upward, the buffer column 33 pulls the buffer tube 34 upward, and the buffer tube 34 pulls the collection box 7 upward. The collection box 7 pulls the protective cover 8 upward through the connecting pipe 35, thereby pulling the protective cover 8 to a higher place. When the thickness of the door panel changes, the protective cover 8 is always at the top of the door panel.

[0055] When the door panel is being cut, the driving assembly moves the protective cover 8 to the top of the door panel, thereby enabling the protective cover 8 to come into contact with door panels of different thicknesses, further improving the applicability of the protective cover 8.

[0056] The above describes several embodiments of the present invention in detail, but the embodiments of the present invention are not limited to these and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
