Then, a negative pressure is generated inside the pressure cavity on the fixed disk, and the negative pressure adsorbs and contracts the first adsorption disk, reducing the air pressure in the space between the second adsorption disk and the new circular saw blade, achieving the effect of making the second adsorption disk adsorb the new circular saw blade more tightly.

[0026] Third: When replacing the old circular saw blade, by controlling the cleaning air pump to start, high-speed gas is sprayed onto both side surfaces of the old circular saw blade through the conduit and the injection cylinder to remove the debris and dust on the surface and edges of the old circular saw blade, preventing the debris and dust from contaminating the motor output shaft, and achieving the effect of protecting the equipment.

The top ends of the vertical frame are respectively fixedly connected with a plurality of spraying cylinders 21, and a stop block 22 is fixedly connected to one side of the vertical frame.

[0043] In this embodiment, when replacing the old circular saw blade 23, by controlling the start of the cleaning air pump 3, high-speed gas is sprayed onto both side surfaces of the old circular saw blade 23 through the conduit pipes 24 and the spraying cylinders 21, removing the debris and dust of the waste materials on the surface and edge of the old circular saw blade 23, preventing the debris and dust from contaminating the motor output shaft, and achieving the effect of protecting the equipment.

[0044] Refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 In a preferred embodiment, the robotic arm mechanism includes a second control motor 9 fixedly connected to one side of the slide rail plate 8. A first control motor 11 is fixedly connected to a position above the second control motor 9 on one side of the slide rail plate 8. One end of the output shaft of the second control motor 9 is fixedly connected with a second swing plate 14. The surface of the second swing plate 14 is provided with a second sliding groove. One end of the output shaft of the first control motor 11 is fixedly connected with a first swing plate 12. The surface of the first swing plate 12 is provided with a first sliding groove.

[0045] One end of the robotic arm 7 is provided with a picking mechanism, and the picking mechanism is used to pick up the new circular saw blade 31.

[0046] In this embodiment, by starting the second control motor 9 and the first control motor 11, the first sliding rod and the second sliding rod respectively slide to one side inside the first sliding groove 10 and the second sliding groove 13, causing the robotic arm 7 to slide to one side. At the corner of the first sliding groove 10, the second sliding rod stops sliding, and the first sliding rod slides downward to the bottom position of the first sliding groove 10.

[0047] Refer to Figure 1 、Figure 2 , Figure 5 and Figure 6 , in a preferred embodiment, the picking mechanism includes an adsorption air pump 32 fixedly connected to one end of the robotic arm 7. A connecting pipe 34 is inserted at the bottom of the adsorption air pump 32, and an air pipe 33 is inserted on one side of the adsorption air pump 32;

[0048] One end of the robotic arm 7 is equipped with an adsorption mechanism for adsorbing a new circular saw blade 31.

[0049] The adsorption mechanism includes a fixed disk 35 fixedly connected to one end of the robotic arm 7. A pressure cavity 38 is arranged inside the fixed disk 35. A second adsorption disk 37 is arranged on one side of the fixed disk 35, and a first adsorption disk 36 is arranged on the inner wall on one side of the second adsorption disk 37.

[0050] In this embodiment, by starting the adsorption air pump 32, exhausting through the connecting pipe 34, and inhaling through the air pipe 33, the air pressure inside the pressure cavity 38 on the fixed disk 35 is made higher than the atmospheric pressure, causing the fixed disk 35 to expand and deform, so that the second adsorption disk 37 adsorbs on the surface of the new circular saw blade 31. By inhaling through the connecting pipe 34 and exhausting through the air pipe 33, a negative pressure is generated inside the pressure cavity 38 on the fixed disk 35. The negative pressure adsorbs the first adsorption disk 36 to cause contraction, reducing the air pressure in the space between the second adsorption disk 37 and the new circular saw blade 31, achieving the effect of making the second adsorption disk 37 adsorb the new circular saw blade 31 more tightly.

[0051] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in a preferred embodiment, the transposition mechanism includes a fixed frame 26 fixedly connected to the upper surface of the fixed plate 17. A fixed frame 26 is fixedly connected to one side of the fixed frame 26. A ball screw 30 is arranged at the output end of the fixed frame 26. A transmission threaded rod is rotatably connected inside the ball screw 30. One end of the transmission threaded rod is threadedly connected to a slider 28. A travel switch 27 is fixedly connected to one side of the slider 28. A sliding plate 29 is fixedly connected to the top of the slider 28. A cutting motor 15 is fixedly connected to the upper surface of the sliding plate 29. A base is fixedly connected to the upper surface of the sliding plate 29. A rotating shaft is rotatably connected inside the base. One end of the rotating shaft is sleeved with a buffer spring. The other end of the rotating shaft is fixedly connected to a threaded column 40. One end of the threaded column 40 is sleeved with an old circular saw blade 23;

[0052] One end of the output shaft of the cutting motor 15 is equipped with a transmission mechanism for rotating the old circular saw blade 23.

[0053] The transmission mechanism includes a driving wheel 19 fixedly connected to one end of the output shaft of the cutting motor 15. One end of the rotating shaft is fixedly connected to a driven wheel 20. A belt 18 is arranged between the driving wheel 19 and the driven wheel 20;

[0054] One end of the output shaft of the installation motor 2 is provided with an installation mechanism for removing the old circular saw blade 23.

[0055] In this embodiment, when the cutting motor 15 is started, the driving wheel 19 and the belt 18 drive the driven wheel 20 to rotate, so that the rotating shaft rotates, and then the old circular saw blade 23 rotates to cut the material. After long-term use, it is necessary to replace the old circular saw blade 23. The moving motor 16 is started to drive the transmission threaded rod to rotate, so that the slider 28 and the sliding plate 29 slide forward, the cutting motor 15 and the old circular saw blade 23 slide forward, and the old circular saw blade 23 is moved to a suitable position to facilitate subsequent replacement operations.

[0056] Refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8 In a preferred embodiment, the installation mechanism includes two connecting frames 41 fixedly connected to one end of the output shaft of the installation motor 2. A fixing pin 42 is slidably connected to the top of the connecting frame 41. One end of the fixing pin 42 is sleeved with a limiting spring 45. A limiting block 44 is fixedly connected to the outer wall of one side of the connecting frame 41 near the limiting spring 45. One end of the threaded column 40 is threadedly connected to a connecting cylinder 39, and an internal thread 43 is provided inside the connecting cylinder 39.

[0057] The first sliding rod slides in the first sliding groove, the second sliding rod slides in the second sliding groove, and the injection cylinder 21 is communicated with the catheter 24 respectively.

[0058] One end of the connecting pipe 34 is communicated with the fixed disk 35. The fixed disk 35, the first suction disk 36 and the second suction disk 37 are made of flexible materials. The connecting cylinder 39 and the limiting block 44 are slidably connected, the threaded column 40 and the internal thread 43 are used in cooperation, and one end of the transmission threaded rod is fixedly connected to one end of the output shaft of the moving motor 16.

[0059] In this embodiment, the threaded column 40 and the connecting cylinder 39 at the center of the old circular saw blade 23 slide forward until one end of the connecting cylinder 39 is sleeved on the output shaft of the installation motor 2. The position of the connecting cylinder 39 is limited by the limiting block 44. One end of the connecting cylinder 39 presses the fixing pin 42 to compress the limiting spring 45 until the fixing pin 42 is stuck on the surface of the connecting cylinder 39. The installation motor 2 and the cutting motor 15 rotate in the reverse direction to separate the threaded column 40 from the inside of the internal thread 43. The moving motor 16 rotates in the reverse direction to make the cutting motor 15 and the old circular saw blade 23 slide backward. The threaded column 40 is separated from the old circular saw blade 23, and the old circular saw blade 23 falls off from the threaded column 40 and the connecting cylinder 39 into the discharge slot, playing a role in automatically collecting the old circular saw blade 23.

[0060] Further, by controlling the moving motor 16 to make the cutting motor 15 and the old circular saw blade 23 slide forward, the threaded post 40 passes through the center of the new circular saw blade 31 and contacts the internal thread 43. Similarly, by rotating the mounting motor 2 and the cutting motor 15 in the reverse direction, the threaded post 40 is fixed inside the internal thread 43, and the connecting cylinder 39 fixes the new circular saw blade 31 at one end of the rotating shaft. Then, control the moving motor 16 to make the new circular saw blade 31 return to its original position, and the cutting motor 15 drives the new circular saw blade 31 to rotate to continue the cutting operation, achieving the effect of automatic tool change.

[0061] Working principle: When in use, start the cutting motor 15. The driving wheel 19 and the belt 18 drive the driven wheel 20 to rotate, causing the rotating shaft to rotate, and thus the old circular saw blade 23 rotates to cut the material. After long-term use, it is necessary to replace the old circular saw blade 23. Start the moving motor 16 to drive the transmission threaded rod to rotate, causing the slider 28 and the sliding plate 29 to slide forward, making the cutting motor 15 and the old circular saw blade 23 slide forward, and making the threaded post 40 at the center of the old circular saw blade 23 and the connecting cylinder 39 slide forward until one end of the connecting cylinder 39 is sleeved on the output shaft of the installation motor 2. The position of the connecting cylinder 39 is restricted by the limit block 44. One end of the connecting cylinder 39 presses against the fixing pin 42, compressing the limit spring 45 until the fixing pin 42 is stuck on the surface of the connecting cylinder 39. The installation motor 2 and the cutting motor 15 rotate in the reverse direction, causing the threaded post 40 to disengage from the internal thread 43. Reverse the rotation of the moving motor 16 to make the cutting motor 15 and the old circular saw blade 23 slide backward. The threaded post 40 is separated from the old circular saw blade 23, and the old circular saw blade 23 disengages from the threaded post 40 and the connecting cylinder 39 and falls into the discharge slot, serving the function of automatically collecting the old circular saw blade 23. By starting the adsorption air pump 32, exhausting through the connecting pipe 34 and inhaling through the air pipe 33, a pressure higher than the atmospheric pressure is generated inside the pressure cavity 38 on the fixed disk 35, causing the fixed disk 35 to expand and deform, and making the second adsorption disk 37 adsorb on the surface of the new circular saw blade 31. By inhaling through the connecting pipe 34 and exhausting through the air pipe 33, a negative pressure is generated inside the pressure cavity 38 on the fixed disk 35. The negative pressure adsorbs the first adsorption disk 36 to cause contraction, reducing the air pressure in the space between the second adsorption disk 37 and the new circular saw blade 31, achieving the effect of making the second adsorption disk 37 adsorb the new circular saw blade 31 more tightly. By starting the second control motor 9 and the first control motor 11, the first sliding rod and the second sliding rod slide to one side inside the first sliding groove 10 and the second sliding groove 13 respectively, making the robotic arm 7 slide to one side. At the corner of the first sliding groove 10, the second sliding rod stops sliding, and the first sliding rod slides downward to the bottom position of the first sliding groove 10. One end of the robotic arm 7 lifts the new circular saw blade 31. By controlling the second control motor 9, the second sliding rod slides in the downward arc stage of the second sliding groove 13, making one end of the robotic arm 7 place the new circular saw blade 31 in a suitable position, on one side of the threaded post 40 on the rotating shaft. Similarly, by controlling the moving motor 16, the cutting motor 15 and the old circular saw blade 23 slide forward, making the threaded post 40 pass through the center of the new circular saw blade 31 and contact the internal thread 43. Similarly, by rotating the installation motor 2 and the cutting motor 15 in the reverse direction, the threaded post 40 is fixed inside the internal thread 43, and the connecting cylinder 39 fixes the new circular saw blade 31 at one end of the rotating shaft. Control the moving motor 16 to make the new circular saw blade 31 return to its original position, and the cutting motor 15 drives the new circular saw blade 31 to rotate to continue the cutting operation, achieving the effect of automatically replacing the tool. When replacing the old circular saw blade 23, start the cleaning air pump 3 by control.High-speed gas is sprayed onto both side surfaces of the used circular saw blade 23 through the conduit 24 and the injection cylinder 21 to remove debris and dust from the surface and edges of the seven scraps of the used circular saw blade 23, preventing the debris and dust from contaminating the motor output shaft and achieving the effect of protecting the equipment.
