Detailed implementation manners

[0017] In order to make the objectives, technical solutions, and advantages of the technical solution of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of specific embodiments of the present invention. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0018] Refer to Figure 1 , an embodiment of the present invention provides a fully automatic profile milling and grooving machine based on a PLC, which includes a workbench 1. A side of the upper end of the workbench 1 is fixedly connected with a surrounding plate 2. A profile positioning module 3 is assembled on the upper end of the workbench 1. A moving milling and grooving module 4 is also assembled on the upper end of the workbench 1. A PLC control box 8 is arranged on one side outside the moving milling and grooving module 4. A moving cleaning module 5 is assembled between the lower end of the workbench 1 and the side of the moving milling and grooving module 4. An operating arm 6 is fixedly connected to the back of the workbench 1. A profile transfer module 7 is assembled on the upper end of the operating arm 6. The PLC control box 8 is used to control the operation of the entire device. The PLC control box 8 is a prior art and will not be described in detail herein.

[0019] By controlling the operation of the entire device via the PLC control box 8, the profile transfer module 7 automatically transfers the profile onto the workbench 1. The profile positioning module 3 on the workbench 1 positions the profile. Then, the moving milling and grooving module 4 performs milling and grooving on the positioned profile. After the milling and grooving are completed, the moving cleaning module 5 flushes the processed profile. After the cleaning is completed, the profile transfer module 7 transfers the processed profile away, thereby realizing the automatic feeding, positioning, milling and grooving, cleaning, and discharging of the profile, achieving the full-automatic processing of the profile, reducing the labor cost, and greatly improving the processing efficiency of the profile.

[0020] Refer to Figure 2 , a number of water outlet holes are reserved on the workbench 1 and inside the surrounding plate 2 to ensure that the waste water from the cleaning can be drained away.

[0021] Refer to Figure 1 And Figure 2, the profile positioning module 3 includes a pair of slideways A31 opened at the upper end of the workbench 1 and a servo motor A33 fixed to one side of the workbench 1. A lead screw A32 is rotatably assembled in the slideway A31. One side of the lead screw A32 is connected to the output end of the servo motor A33. The thread directions on the lead screws A32 in the pair of slideways A31 are opposite. Each thread on the lead screws A32 in the pair of slideways A31 is connected to a slider A34. A hydraulic rod A35 is fixedly penetrated through the slider A34. The output end of the hydraulic rod A35 is fixedly connected to a movable block 36. One side of the movable block 36 is fixedly connected to a servo motor B37. The output end of the servo motor B37 passes through the movable block 36 and is fixedly connected to a positioning block 38. When the profile is placed on the workbench 1, the servo motor A33 drives the lead screw A32 to rotate. The lead screw A32 drives the slider A34 to slide in the slideway A31, and then locks and positions both sides of the profile. Then, the milling groove module 4 is moved to mill the groove on the profile. After the milling of this side of the profile is completed, the hydraulic rod A35 extends, and then the locked profile is lifted. The servo motor B37 drives the positioning block 38 to rotate, and then drives the locked profile to perform a rotation and surface change. The hydraulic rod A35 shortens, and then the locked profile is placed on the workbench 1. Then, the milling groove module 4 is moved to mill the groove on the profile. When the profile is completely processed, the moving cleaning module 5 flushes both side walls of the profile. After the flushing of both side walls is completed, the hydraulic rod A35 extends, and then the locked profile is lifted. The servo motor B37 drives the positioning block 38 to rotate, and then drives the locked profile to perform a rotation and surface change. The hydraulic rod A35 shortens, and then the locked profile is placed on the workbench 1. The moving cleaning module 5 continues to flush the other two sides of the profile. After the complete flushing is completed, after the flushing is completed, the servo motor A33 drives the lead screw A32 to reverse, and then the positioning block 38 returns to its position, releasing the profile. The profile transfer module 7 transfers the processed profile away.

[0022] Refer to Figures 1-3, the mobile milling groove module 4 includes slideways C410 reserved on both longitudinal sides of the upper end of the workbench 1 and servo motors E411 fixedly connected to both longitudinal sides of one side of the workbench 1. A lead screw C412 is rotatably connected in the slideway C410. One side of the lead screw C412 is fixedly connected to the output end of the servo motor E411. A slider C413 is threaded on the lead screw C412. The upper end of the slider C413 is fixedly connected to a concave frame 41. A cross bar 42 is movably assembled in the concave frame 41. A hydraulic rod B43 is fixedly connected to the upper end of the concave frame 41. The output end of the hydraulic rod B43 is fixedly connected to the cross bar 42. One side of the cross bar 42 passes through the concave frame 41 and is fixedly connected to a servo motor C44. A slideway B45 is reserved in the cross bar 42.

The output end of the servo motor D48 is detachably assembled with a milling groove blade 49. When performing milling, the servo motor C44 drives the lead screw B46 to rotate. The lead screw B46 drives the slider B47 to move, and then the milling groove blade 49 on the servo motor D48 is moved to the milling groove position of the profile. The servo motor D48 drives the milling groove blade 49 to rotate. The hydraulic rod B43 extends, and then drives the cross bar 42 to move downward to the required position. The servo motor E411 drives the lead screw C412 to rotate. The lead screw C412 drives the slider C413 to slide in the slideway C410, and then drives the concave frame 41 to move, so that the milling groove blade 49 moves back and forth to perform milling on the profile.

[0023] Referring to Figure 1 and Figure 4 , the mobile cleaning module 5 includes a concave channel 51 fixedly connected to the concave frame 41 and a water tank 52 placed at the lower end of the workbench 1. A filter screen is detachably assembled in the water tank 52. The upper end of the concave channel 51 is connected to a steel pipe 55. One side of the water tank 52 is connected to a water pump 53. The other side of the water pump 53 is connected to the steel pipe 55 through a hose 54. A number of nozzles 56 are connected to the inner wall surfaces of both sides of the concave channel 51. When it is necessary to clean the profile, the water pump 53 pumps the water in the water tank 52 into the hose 54, then transports it to the concave channel 51 through the steel pipe 55, and finally sprays it out through the nozzles 56. At the same time, it drives the profile to perform mobile flushing under the drive of the moving concave frame 41, realizing automatic cleaning of the profile for subsequent processing of the profile. And the water after cleaning falls from the workbench 1 into the water tank 52 and is filtered by the filter screen in the water tank 52 so that the water can be recycled, reducing the processing cost.

[0024] Referring to Figure 1 and Figures 5-14, the profile transfer module 7 includes a track A71. The two horizontal sides of the track A71 are fixedly connected with connecting seats 72.

The upper end of the core traction unit 73 is fixedly connected with a changing unit 74. Embedding interfaces 75 are assembled on the longitudinal two side walls of the track A71. The two horizontal sides of the lower end of the changing unit 74 are both assembled with vertical changing parts 77. A fastening platform 76 is assembled at the bottom of the vertical changing part 77. The center of the lower end of the fastening platform 76 is fixedly connected with a track B78. A track C79 is assembled at the lower end of the track B78. An embedding platform 711 is fixedly connected to the upper end of the track C79. The embedding platform 711 is movably assembled in the track B78. The embedding platform 711 can move along the track B78. A deformation part C712 located in the track B78 is fixedly connected to the side of the embedding platform 711 farther from the core traction unit 73. The other side of the deformation part C712 is fixedly connected to the inner side of the track B78. Tracks D710 are fixedly connected to the longitudinal two sides of the track C79. A supporting part 713 is assembled at the lower end of the track C79. The supporting part 713 is movably connected to the corresponding track C79 and track D710. An outer cylinder C714 is fixedly connected to the side of the track C79 farther from the core traction unit 73. A changing column C715 is movably assembled in the outer cylinder C714. The changing column C715 passes through the outer cylinder C714 and one side of the track C79 and is connected to the supporting part 713. The side of the outer cylinder C714 farther from the core traction unit 73 is connected to the vertical changing part 77. The track B78 is flush with one side of the fastening platform 76. When the deformation part C712 is in the initial state, one side of the track C79 extends out of one side of the fastening platform 76. When the deformation part C712 is in the shortened state, one side of the track C79 is flush with one side of the fastening platform 76.

[0025] Before the transfer, the profile transfer module 7 is fixedly connected with the operating arm 6 through the connecting seats 72 on both sides of the track A71, and an external air inflator 716 is connected to the core traction unit 73, and it is ensured that there is no high-pressure air inside the core traction unit 73, and all the air inside the profile transfer module 7 is exhausted, and the profile transfer module 7 is returned to the initial state to perform the locking and transfer of the profile again.

[0026] Refer to Figures 6-8, the core traction unit 73 includes switch A731 and the inflator 716 assembled on the operating arm 6. The upper end of switch A731 is connected to the center of the lower end of track A71. The lower end of switch A731 is connected to switch B732. Switch B732 and the inflator 716 are connected via a rubber tube. The core traction unit 73 also includes outer cylinder A733. The lower end of outer cylinder A733 is connected to the center of the upper end of track A71. Both longitudinal sides of switch A731 are connected to pipe A737. The other side of pipe A737 is connected to both sides of the lower end of outer cylinder A733. A rubber table A734 is movably assembled inside outer cylinder A733. The upper end of rubber table A734 is fixedly connected to the variable column A735. The upper end of variable column A735 passes through the upper end of outer cylinder A733 and is connected to the variable unit 74. A deformable member A736 is clamped on the outer peripheral surface of variable column A735. The vertical sides of deformable member A736 are respectively fixedly connected to the upper end inside outer cylinder A733 and the upper end of rubber table A734.

[0027] When performing locking and transporting of the profile, the profile transport module 7 can be moved above the profile, and by connecting the inflator 716, strong pressure air can be injected into switch B732. At this time, the strong pressure air can flow into switch A731. At this time, by opening the interfaces on both longitudinal sides of switch A731, the strong pressure air flow can be transported through pipe A737 into outer cylinder A733. With the inflow of the strong pressure air flow, at this time, rubber table A734 moves upward under the pressure of the air flow, and pulls variable column A735 to move upward. At this time, deformable member A736 shortens under the pressure, and finally transmits this force to the position of variable unit 74.

[0028] Refer to Figure 7 、 Figure 9 And Figure 10 , the variable unit 74 includes a variable piece 741. The lower end center of the variable piece 741 is connected to the upper end of the variable column A735. Both sides in the length direction of the lower end of the variable piece 741 are fixedly connected with connection platforms A742. The side of connection platform A742 farther from the variable piece 741 is rotatably connected with a connection bar A744. The side of connection bar A744 farther from the connection platform A742 is rotatably connected with a connection platform B743. The lower end of the connection platform B743 is fixedly connected to a variable table 745. The variable table 745 is movably assembled in the socket 75. The variable table 745 can move along the socket 75. Both longitudinal sides of the variable table 745 are rotatably connected with rotating tables 746. The surface of the rotating table 746 is in contact with the inner surface of the socket 75. A deformable rod 747 is assembled on the walls of a pair of variable tables 745 facing away from each other.

[0029] When the movable column A735 moves upward, the movable piece 741 also moves upward at this moment. At this time, the span between the movable piece 741 and the track A71 becomes larger. At this moment, the connecting bar A744 rotates towards the center and drags the connecting platform B743. At this time, a pair of movable platforms 745 move in the insertion opening 75. The pair of movable platforms 745 approach each other, and then pull the pair of vertical moving parts 77 closer to each other, and finally pull the pair of fastening platforms 76 closer to each other until the fastening platform 76 is in contact with the side wall of the profile, thus achieving the first locking of the profile. When unlocking the profile, the air in the outer cylinder A733 is discharged. At this time, the core traction unit 73 can return to its original position by itself, and the moving unit 74 can also return to its original position by itself. Then, the pair of movable platforms 745 move away from each other, unlocking the profile, and the deformation rod 747 can be in contact with the side wall of the insertion opening 75 to reduce the impact of the movable platform 745.

[0030] Refer to Figure 6 、 Figure 11 and Figure 12 , the vertical moving part 77 includes an outer cylinder B771. The upper end of the outer cylinder B771 is connected to the lower end of the movable platform 745. One side of the outer cylinder B771 close to the core traction unit 73 is connected to the pipeline B775, and the pipeline B775 is connected to the horizontal sides of the switch A731. The side of the outer cylinder B771 far from the core traction unit 73 is connected to the pipeline C776, and the other side of the pipeline C776 is connected to the outer cylinder C714. A rubber platform B772 is movably assembled in the outer cylinder B771. The lower end of the rubber platform B772 is fixedly connected to the movable column B773. The lower end of the movable column B773 passes through the lower end of the outer cylinder B771 and is connected to the upper end of the fastening platform 76. A deformation piece B774 is hoop-mounted on the outer peripheral surface of the movable column B773. The vertical sides of the deformation piece B774 are respectively fixedly connected to the lower end of the rubber platform B772 and the lower end inside the outer cylinder B771.

[0031] When locking and transporting profiles with a large vertical span, by opening the interfaces on the horizontal sides of the switch A731, strong pressure air can be filled into the outer cylinder B771 through the pipeline B775 at this time, and the rubber platform B772 is pressed. At this time, the deformation piece B774 shortens, pulling the movable column B773 downward and driving the fastening platform 76 downward. At this time, the fastening platform 76 moves along the side wall of the profile towards the lower end of the profile to lock the lower end of the profile, and can also pull the track B78 and the track C79 downward together until the upper end of the track C79 moves to the lower end of the profile, thus achieving the locking and transportation of profiles with a large vertical span.

[0032] By filling gas into the vertical moving part 77, the fastening platform 76 moves downward to a position close to the lower end of the profile, achieving the locking and transportation of profiles with different vertical spans, reducing the limitations of the profile transportation module 7, and ensuring the stable locking and transportation of profiles.

[0033] Refer to Figure 5 、 Figure 11 、 Figure 13 and Figure 14 Figure 14 , the supporting part 713 includes a guiding platform A7131, which is movably assembled in the track C79. The guiding platform A7131 can move along the track C79. The side of the guiding platform A7131 farther from the core traction unit 73 is connected to the moving column C715. The lower end of the guiding platform A7131 is fixedly connected to the main supporting platform 7132. The supporting part 713 also includes a guiding platform B7133, which is movably assembled in the track D710. The guiding platform B7133 can move in the track D710. The lower ends of the guiding platforms B7133 are all fixedly connected to the side supporting platforms 7134. The side of the side supporting platform 7134 close to the core traction unit 73 is flush with one side of the track C79. The longitudinal sides of the lower end of the main supporting platform 7132 are all fixedly connected to the connecting platform C7135. The lower ends of the side supporting platforms 7134 are all fixedly connected to the connecting platform D7136. The connecting platform C7135 and the connecting platform D7136 are rotatably connected through a connecting bar B7137.

[0034] When the track C79 has not descended to the lower end of the profile, due to the cooperation of the side wall of the profile, it exerts a certain pressing force on the side wall of the track C79. At this time, the deformation part C712 shrinks, and the embedding table 711 moves outward and pulls the track C79 to move outward until one side of the track C79 is flush with one side of the fastening table 76.

[0035] When the track C79 descends to the lower end of the profile, at this time, the deformation part C712 returns to its original position by itself and pulls the track C79 to return to its original position by itself. At this time, the profile makes a change in the middle, and some air in the core traction unit 73 can be discharged, increasing the span between the pair of fastening tables 76. At this time, the fastening tables 76 cancel the pressing on the side wall of the profile. At this time, the profile moves downward, and the lower end of the profile fits with the upper ends of the side supporting platform 7134 and the main supporting platform 7132 to realize the support of the profile; And the gas in the input outer cylinder B771 can be discharged through the pipe C776 and flows into the outer cylinder C714, and pulls the moving column C715 to move toward the side close to the profile. At this time, the guiding platform A7131 moves toward the middle of the profile, and pulls the main supporting platform 7132 to move toward the middle of the profile, enhancing the supporting function. And when the guiding platform A7131 moves toward the middle, at this time, several connecting bars B7137 open outward, driving the guiding platform B7133 to move. At this time, the pair of guiding platforms B7133 move outward, and finally pull several side supporting platforms 7134 to move toward the corners of the profile to realize the stable support of the profile.

[0036] After the outer cylinder C714 and the supporting part 713 act through the filled gas and lock the side wall of the profile, they can automatically change the locking of the opposite side wall into the support of the lower end, and change the support of the center into the support of the four corners, enhancing the stability of the support, and then ensuring the stability during the transfer of the profile.

[0037] When performing the transfer of the profile, before the transfer, the profile transfer module 7 and the operating arm 6 are fixedly connected through the connecting seats 72 on both sides of the track A71, and the external inflator 716 and the core traction unit 73 are connected. In addition, it is ensured that there is no high-pressure air inside the core traction unit 73, and all the air inside the profile transfer module 7 is exhausted, turning the profile transfer module 7 into the initial state for performing the locking transfer of the profile again. When performing the locking transfer of the profile, the profile transfer module 7 can be moved onto the profile, and by connecting the inflator 716, high-pressure air can be injected into the switch B732. At this time, the high-pressure air can flow into the switch A731. At this time, by opening the interfaces on both longitudinal sides of the switch A731, the high-pressure air flow can be transported to the outer cylinder A733 through the pipe A737. With the inflow of the high-pressure air flow, at this time, the rubber table A734 moves upward under the pressure of the air flow, and drives the moving column A735 to move upward. At this time, the deformable part A736 shortens under the pressure, and finally transmits this force to the position of the moving unit 74. When the moving column A735 moves upward, at this time, the moving piece 741 moves upward. At this time, the span between the moving piece 741 and the track A71 becomes larger. At this time, the connecting bar A744 rotates towards the center and drags the connecting table B743. At this time, a pair of moving platforms 745 move in the socket 75, and the pair of moving platforms 745 approach each other, and drive a pair of vertical moving parts 77 to approach each other, and finally drive a pair of fastening platforms 76 to approach each other until the fastening platforms 76 are in contact with the side wall of the profile, and the first locking of the profile is achieved. When canceling the locking of the profile, the air inside the outer cylinder A733 is exhausted. At this time, the core traction unit 73 can automatically return to its original position, and the moving unit 74 can automatically return to its original position. Then, a pair of moving platforms 745 move away from each other to cancel the locking of the profile, and the deformation rod 747 can be in contact with the side wall of the socket 75 to slow down the impact of the moving platform 745. When performing locking and transferring on profiles with a relatively large vertical span, by opening the interfaces on both horizontal sides of switch A731, strong compressed air can be filled into outer cylinder B771 through pipe B775 at this moment, and rubber platform B772 is pressed. At this time, deformable part B774 shortens, and traction change column B773 moves downward, and drives fastening platform 76 to move downward. At this time, fastening platform 76 moves along the side wall of the profile towards the lower end of the profile, locks the lower end of the profile, and can also drive track B78 and track C79 to move downward together until the upper end of track C79 moves to the lower end of the profile, and the locking and transferring of profiles with a relatively large vertical span can be achieved; By filling gas into vertical moving part 77, fastening platform 76 moves downward, and it moves to a position close to the lower end of the profile, achieving the locking and transferring of profiles with different vertical spans, reducing the limitations of profile transfer module 7, and ensuring the stable locking and transferring of profiles; When track C79 drops to the lower end of the profile, at this time, deformable part C712 returns to its original position by itself and drives track C79 to return to its original position by itself. At this time, the center of the profile moves, and some air in core traction unit 73 can be discharged, increasing the span between a pair of fastening platforms 76. At this time, fastening platform 76 cancels the pressure on the side wall of the profile. At this time, the profile moves downward, and the lower end of the profile fits with the upper ends of side support platform 7134 and main support platform 7132, realizing the support of the profile; And the gas input into outer cylinder B771 can be discharged through pipe C776 and flows into outer cylinder C714, and drives change column C715 to move towards the side close to the profile. At this time, guiding platform A7131 moves towards the center close to the profile, and drives main support platform 7132 to move towards the center of the profile, enhancing the support function. And when guiding platform A7131 moves towards the center, at this time, several connecting strips B7137 open outwards, driving guiding platform B7133 to move. At this time, a pair of guiding platforms B7133 move outwards, and finally drive several side support platforms 7134 to move towards the corners of the profile, realizing the stable support of the profile.
