[0033] As Figures 1 to 2 shown, in one embodiment, a loading and unloading device 1 of a laser cutting machine includes a chassis 10 and a material transporting assembly 20. The material transporting assembly 20 includes a support frame 21, a top frame 22, a plurality of telescopic members 23 and a plurality of material suction members 24. The support frame 21 is rotatably arranged on the chassis 10. Each telescopic member 23 is rotatably arranged on the chassis 10, and the output end of each telescopic member 23 is rotatably connected to the support frame 21. The plurality of telescopic members 23 together drive the support frame 21 to reciprocally swing relative to the chassis 10. The top frame 22 is arranged at one end of the support frame 21 away from the chassis 10. The support frame 21 drives the top frame 22 to approach or move away from the sheet material. The plurality of material suction members 24 are arranged at intervals on the top frame 22, and each material suction member 24 is used to suck the sheet material.

[0034] It should be noted that the chassis 10 is a frame structure with multiple crossbars in the middle. One side of the chassis 10 is provided with an outstretched side frame, which is connected to the laser cutting machine. For example, the side frame is screwed to the bottom of the laser cutting machine through screws, so that the chassis 10 is fixed on the laser cutting machine. Further, the support frame 21 includes four vertical rods 211. One end of each of the four vertical rods 211 is rotatably arranged on the chassis 10, and the four vertical rods 211 are divided into two groups with two vertical rods 211 in each group, and are respectively located at both ends of the chassis 10. Specifically, two of the vertical rods 211 are arranged at intervals at one end of the chassis 10, and the other two vertical rods 211 are arranged at intervals at the other end of the chassis 10. It should be noted that the two vertical rods arranged at one end of the chassis 10 are staggered from each other, so that when the two vertical rods swing to be parallel to the chassis 10, the two vertical rods 211 can be on the same horizontal plane. The support frame 21 further includes a frame body 212, and the frame body 212 is a quadrilateral structure. The ends of the two groups of vertical rods 211 far away from the chassis 10 are rotatably connected to both ends of the frame body 212, so that when the two groups of vertical rods 211 swing relative to the chassis 10, the frame body 212 can be driven to swing. Since the four vertical rods 211 are all rotatably arranged in parallel on the chassis 10, the frame body 212 can maintain a horizontal state when moving between the plate placing area and the material feeding area of the laser cutting machine.

[0035] As Figures 1 to 2 shown, in an embodiment, the material transporting assembly 20 includes a plurality of telescopic members 23. Each telescopic member 23 is a hydraulic rod structure. There are four telescopic members 23, and the four telescopic members 23 correspond to the four vertical rods 211 one by one. The four telescopic members 23 are all rotatably arranged on the chassis 10, and the output ends of the four telescopic members 23 are rotatably connected to the four vertical rods 211.

[0036] It should be noted that the four telescopic members 23 are rotatably connected to the four vertical rods 211 in an alternating manner. For the convenience of description, the four telescopic members 23 are respectively defined as the first telescopic member 23, the second telescopic member 23, the third telescopic member 23, and the fourth telescopic member 23, and the four vertical rods 211 are respectively defined as the first vertical rod 211, the second vertical rod 211, the third vertical rod 211, and the fourth vertical rod 211. One ends of the first vertical rod 211 and the second vertical rod 211 are rotatably arranged at one end of the chassis 10, and the third vertical rod 211 and the fourth vertical rod 211 are rotatably arranged at the other end of the chassis 10, and the four vertical rods 211 are respectively close to the four corner positions of the chassis 10. The first telescopic member 23 is located on one side of the first vertical rod 211 and close to the four corner positions of the chassis 10, the second telescopic member 23 is located on one side of the second vertical rod 211 and close to the four corner positions of the chassis 10, the third telescopic member 23 is located on one side of the third vertical rod 211 and close to the four corner positions of the chassis 10, and the fourth telescopic member 23 is located on one side of the fourth vertical rod 211 and close to the four corner positions of the chassis 10. Further, the output end of the first telescopic member 23 is rotatably connected to the first vertical rod 211, the output end of the second telescopic member 23 is rotatably connected to the second vertical rod 211, the output end of the third telescopic member 23 is rotatably connected to the third vertical rod 211, and the output end of the fourth telescopic member 23 is rotatably connected to the fourth vertical rod 211. Since the telescopic members 23 and the vertical rods 211 are arranged in an alternating manner, and the other ends of the vertical rods 211 are all rotatably connected to the frame body 212, when it is necessary to move the frame body 212 in one direction, the first telescopic member 23 and the third telescopic member 23 at both ends of the chassis 10 jointly pull the first vertical rod 211 and the third vertical rod 211, and the second telescopic member 23 and the fourth telescopic member 23 jointly push the third vertical rod 211 and the fourth vertical rod 211. When it is necessary to move the frame body 212 in the opposite direction, the first telescopic member 23 and the third telescopic member 23 at both ends of the chassis 10 jointly push the first vertical rod 211 and the third vertical rod 211, and the second telescopic member 23 and the fourth telescopic member 23 jointly pull the third vertical rod 211 and the fourth vertical rod 211. In this way, the telescopic members 23 jointly drive the vertical frames to swing while maintaining a parallel state.

[0037] As Figures 1 to 2 , Figure 4 shown, in one embodiment, the top frame 22 is rotatably arranged inside the frame body 212.

[0038] It should be noted that the top frame 22 is a frame structure jointly formed by four cross columns, and the two opposite cross columns of the top frame 22 are respectively rotatably connected to the two ends of the frame body 212. Further, the frame body 212 is a frame structure jointly formed by four cross bars, so that the top frame 22 rotatably arranged inside the frame body 212 has enough space to turn over. The two groups of vertical frames are respectively rotatably arranged on the two opposite cross bars of the frame body 212, and two of the opposite cross columns of the top frame 22 are respectively rotatably arranged on the other two cross bars of the frame body 212, so that when the two groups of vertical frames drive the frame body 212 to move horizontally back and forth in a horizontal state, the top frame 22 can also longitudinally turn over relative to the frame body 212.

[0039] As Figures 1 to 2 shown, in one embodiment, the material conveying assembly 20 further includes two driving members 25. The two driving members 25 are arranged on the two opposite ends of the frame body 212, and the output ends of the two driving members 25 are respectively connected to the two opposite ends of the top frame 22, so that the two driving members 25 jointly drive the top frame 22 to turn over.

[0040] It should be noted that rotating columns 221 are arranged on the two opposite cross columns of the top frame 22. The two rotating columns 221 respectively pass through the frame body 212. For the convenience of description, the four cross bars on the frame body 212 are respectively defined as the first cross bar, the second cross bar, the third cross bar and the fourth cross bar. The four cross bars are connected end to end in sequence to form the frame body 212. Further, the two groups of vertical frames are respectively rotatably connected to the first cross bar and the third cross bar, and the two rotating columns 221 on the top frame 22 respectively pass through the second cross bar and the fourth cross bar, and the two rotating columns 221 both extend from the ends of the second cross bar and the fourth cross bar far away from the top frame 22. Further, the two driving members 25 are respectively arranged on the second cross bar and the fourth cross bar, and the output ends of the two driving members 25 are respectively connected to the two rotating columns 221. In this way, the two driving members 25 drive the two rotating columns 221 to rotate so that the top frame 22 turns over.

[0041] As Figures 1 to 2 shown, in one embodiment, a driving member 25 includes a motor 251, a driving wheel 252, a driven wheel 253 and a belt 254. The motor 251 is arranged on the frame body 212. The driving wheel 252 is sleeved on the output end of the motor 251. The driven wheel 253 is sleeved on the rotating column 221. The belt 254 is respectively sleeved on the driving wheel 252 and the driven wheel 253, so that the motor 251 drives the rotating column 221 to rotate.

[0042] It should be noted that a plurality of grooves are formed on each of the two rotating columns 221, and the grooves are arranged at intervals along the circumference of the rotating column 221. The driven wheels 253 on the two driving members 25 are both annular structures, and a plurality of protrusions are arranged on the inner side wall, and the protrusions are arranged at intervals along the inner side wall of the driven wheel 253, and each protrusion corresponds to each groove one by one. When the driven wheel 253 is sleeved on the rotating column 221, the protrusions on the driven wheel 253 will be clamped with the grooves on the rotating column 221. Since the belt 254 is sleeved on the outer side surfaces of the driving wheel 252 and the driven wheel 253 respectively, when the driving member 25 drives the driven wheel 253 to rotate, the driven wheel 253 can drive the rotating column 221 to rotate, so that the top frame 22 can be turned relative to the frame body 212.

[0043] As Figures 1 to 2 , Figure 4 shown, in one embodiment, a plurality of clamping platforms 222 are arranged on the top frame 22, and the clamping platforms 222 are arranged at intervals on the top frame 22, and each clamping platform 222 is used for supporting each material suction member 24.

[0044] It should be noted that a plurality of clamping platforms 222 are respectively arranged at the two ends of the top frame 22 close to the frame body 212 and rotatably connected to the vertical rod 211, and the clamping platforms 222 are distributed at intervals on the upper and lower surfaces of the top frame 22. For the convenience of description, the four cross columns on the top frame 22 are respectively defined as the first cross column, the second cross column, the third cross column and the fourth cross column. The second cross column and the fourth cross column are respectively rotatably connected to the two ends of the frame body 212, and the clamping platforms 222 are respectively arranged on the upper and lower surfaces of the first cross column and the third cross column. Further, each clamping platform 222 tends to be in a "T" - shaped structure, so that both ends of each clamping platform 222 extend from the two side surfaces of the first cross column and the third cross column, and each material suction member 24 is respectively located on the two side surfaces of the first cross column and the third cross column. Since each clamping platform 222 extends from the two side surfaces of the first cross column and the third cross column, the clamping platforms 222 on the upper surface and the clamping platforms 222 on the lower surface jointly support each material suction member 24, so that the top frame 22 drives each material suction member 24 to turn.

[0045] It should be noted that the suction members 24 located on both sides of the first horizontal column and the third horizontal column are arranged in staggered directions. For example, the output end of the suction member 24 on one side of the first horizontal column and the third horizontal column is arranged upward, while the output end of the suction member 24 on the other side of the first horizontal column and the third horizontal column is arranged downward, so that each suction member 24 can perform suction action on the upper and lower surfaces of the top frame 22. For example, in one embodiment, each telescopic member 23 drives each vertical rod 211 to swing so that the frame 212 moves to the plate placement area. During the swinging process, the two driving members 25 will jointly drive the top frame 22 to rotate to be level with the frame 212. When the frame 212 is moved to the plate placement area, the suction members 24 on one side of the top frame 22 suck the plate to be cut downward. After the plate is sucked, each telescopic member 23 drives each vertical rod 211 to swing so that the frame 212 moves to the laser cutting machine discharge area. During the swinging process, the two driving members 25 The two driving members 25 will jointly drive the top frame 22 to rotate, so that the side of the top frame 22 that absorbs the plate is flipped to face upward, and the side of the top frame 22 that does not absorb the plate is flipped to face downward. When the frame 212 moves to the discharge area of the laser cutting machine, the suction members 24 on the side of the top frame 22 that does not absorb the plate will downwardly absorb the plate processed from the laser cutting machine. After the processed plate is absorbed by the suction members 24, the two driving members 25 jointly drive the top frame 22 to flip, so that the upper and lower surfaces of the top frame 22 are swapped, and the unprocessed plate located on the top frame 22 is flipped to the discharge area of the laser cutting machine, and the processed plate under the top frame 22 is also flipped upward. When the two plates in different states are flipped, the unprocessed plate will be sent to the laser cutting machine for processing, and the processed plate will be sent out of the laser cutting machine. This cycle is repeated, and automatic loading and unloading can be completed to improve production efficiency.

[0046] like Figures 2 to 6 As shown, in one embodiment, the material transport assembly 20 further includes a plurality of fastening members 26, each fastening member 26 is correspondingly disposed on each clamping platform 222, and each fastening member 26 is used to clamp each material suction member 24. The fastening member 26 includes a torsion block 261, a tension spring 262, and two hook blocks 263, the two hook blocks 263 are respectively rotatably disposed at both ends of the clamping platform 222, the two ends of the tension spring 262 are respectively connected to the two hook blocks 263, so that the tension spring 262 pulls the two hook blocks 263 away from the material suction member 24, and the torsion block 261 is rotatably disposed on the clamping platform 222, and when the torsion block 261 is rotated by an external force, it drives the two hook blocks 263 to clamp the material suction member 24 together.

[0047] It should be noted that brackets are provided at both ends of the card table 222. Both brackets extend from the two side surfaces of the first cross-column and the third cross-column. Since the card tables 222 are provided on the upper and lower surfaces of the first cross-column and the third cross-column, two brackets extend from each of the two side surfaces of the first cross-column and the third cross-column, and the suction member 24 is located between the two brackets. Further, a card slot 2641 is provided on the bracket. Since the suction member 24 is located between the two brackets, both ends of the suction member 24 are clamped with the card slots 2641 on the two brackets. Further, the fastening member 26 includes a torsion block 261, two tension springs 262 and four hook-shaped blocks 263. Two of the hook-shaped blocks 263 are rotatably arranged on one bracket, and the other two hook-shaped blocks 263 are rotatably arranged on the other bracket, so that the two hook-shaped blocks 263 on one bracket and the two hook-shaped blocks 263 on the other bracket are oppositely arranged at both ends of the card table 222. One end of every two hook-shaped blocks 263 jointly encloses a card slot 2641. Since the two brackets are located at both ends of the card table 222 and two hook-shaped blocks 263 are provided on one bracket, when the suction member 24 is placed between the two brackets, both ends of the suction member 24 are inserted into the card slots 2641 on the two brackets, and then one end of the two hook-shaped blocks 263 on the bracket jointly clamps the suction member 24 to prevent the suction member 24 from sliding out between the two brackets.

[0048] It should be noted that one end of the two hook-shaped blocks 263 on one bracket that is far from the torsion block 261 approaches each other to clamp the suction member 24, and the tension spring 262 is arranged between the two hook-shaped blocks 263 on one bracket, so that the tension spring 262 can pull one end of the two hook-shaped blocks 263 that approaches the suction member 24 away from each other, so that the suction member 24 can slide out of the card slot 2641. When the tension spring 262 pulls one end of the two hook-shaped blocks 263 away from the suction member 24, the other ends of the two hook-shaped blocks 263 will approach each other. Further, the torsion block 261 is rotatably arranged on the card table 222 and is located between the two brackets. When the two tension springs 262 pull one end of the two hook-shaped blocks 263 away from the suction member 24 and approach each other, one end of each hook-shaped block 263 that is far from each suction member 24 abuts against the torsion block 261. Further, the torsion block 261 is of a rhombus structure. When the torsion block 261 is rotated by an external force, the torsion block 261 will push the two hook-shaped blocks 263 to expand outwards, so that one end of the two hook-shaped blocks 263 that approaches the suction member 24 approaches each other to clamp the suction member 24. Since the tension springs 262 are provided on both brackets, the two tension springs 262 respectively pull the two hook-shaped blocks 263 on their respective brackets close to the torsion block 261, and then the torsion block 261 can jointly push one end of each hook-shaped block 263 that approaches the suction member 24 to approach each other. In this way, after each suction member 24 is inserted into the card slot 2641, it cannot fall off.

[0049] As Figures 3 to 4As shown, in one embodiment, the material suction member 24 includes a cylinder body 241, a shaft rod 242, a connection head 243 and a suction cup 244. The shaft rod 242 is disposed inside the cylinder body 241 so that the shaft rod 242 can slide relative to the cylinder body 241. The shaft rod 242 is of a hollow structure. The connection head 243 is disposed at one end of the shaft rod 242, and the suction cup 244 is disposed at the other end of the shaft rod 242, and the connection head 243 is in communication with the suction cup 244. When the connection head 243 is connected to an air extraction pump, the air in the suction cup 244 can be pumped, so that the suction cup 244 can adsorb the board.

[0050] As Figures 1 to 2 shown, in one embodiment, the support frame 21 further includes two reinforcing rods. Both ends of the reinforcing rods are rotatably connected to two vertical rods 211 on one side of the base frame 10, so that the two vertical rods 211 on one side of the base frame 10 can be more stable.

[0051] The above embodiments only represent several embodiments of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
