[0017] In the present invention, after the cutting is completed, the staff starts the cylinder, and the cylinder pushes the placement plate to move upward. The placement plate rises along the trajectory of the guide groove through the supporting lifting rod. When the placement plate rises, the limit plate with the pull rod rises together, and the pull rod is separated from the gear. At this time, there is a large gap between the side of the placement plate close to the pull rod and the collection chamber, so the staff can pull the pull rod, the pull rod drives the driving plate to move, and the driving plate drives the limit plate to move. The movement of the limit plate pushes the display screen on the placement plate, and stops when the required display screen is pushed to the edge of the placement plate.

The operation is repeated, and the display screens can be picked up one by one, so that the waste can be unloaded while the required display screen is picked up and collected, and the damage caused by picking up the display screen and the placement plate in a fitted state can also be avoided.

[0018] In the present invention, when the display screen is cut, the air pump is started, and the air pump blows air into the condensation box.

At this time, the top temperature of the placement plate is reduced, thereby cooling the display screen. Since the wind blocking plate is gradually raised from the middle to both sides, the heat dissipation holes can block part of the passing gas, and the blocked gas moves downward, and finally sprays downward through the heat dissipation holes, so that the placement plate takes away the heat of the display screen, and the gas blown downward by the heat dissipation holes can blow the inclined surface of the collection chamber, so as to blow the waste downward for easy discharge and blow the dust on the inclined surface of the collection chamber to avoid excessive dust accumulation.

[0027] In this embodiment, when the display screen is cut, the air pump 21 is started, and the air pump 21 blows air into the condensation box 23. The gas enters the air inlet pipe 428, and then enters the air blowing pipe 425, and then blows to the spaces on both sides of the placement plate 42 through the air heads on both sides of the air blowing pipe 425. At this time, the top temperature of the placement plate 42 is reduced, thereby cooling the display screen. Since the wind blocking plate 424 is gradually raised from the middle to both sides, the heat dissipation hole 423 can block part of the passing gas, and the blocked gas moves downward and is finally sprayed downward through the heat dissipation hole 423, so that the placement plate 42 takes away the heat of the display screen, and the gas blown downward by the heat dissipation hole 423 can blow the inclined surface of the collection chamber 11, thereby blowing the waste downward for easy discharge and blowing the dust on the inclined surface of the collection chamber 11 to avoid excessive dust accumulation.

[0028] Working principle: First, the staff places the display screen on the top of the placement plate 42 and on the side opposite to the limiting plate 412, and pulls the pull rod 415, the pull rod 415 drives the top driving plate 413 to move, the top driving plate 413 drives the limiting plate 412 connected thereto to move, and when the top driving plate 413 moves, the gear 417 can be driven to rotate through the rack 414, the gear 417 drives the bottom driving plate 413 to move, the bottom driving plate 413 drives the limiting plate 412 connected thereto to move, at this time, the two limiting plates 412 move synchronously, thereby limiting the display screen, and then pull the pull ring 324 downward, the pull ring 324 drives the telescopic rod 323 to extend from the fixed tube 321, the telescopic rod 323 drives the gas ring 326 and the telescopic gas rod 325 to move downward, The telescopic gas rod 325 is gradually stretched, and the gas ring 326 drives the gas nozzle 327 to move down to the bottom. During cutting, the laser cutter 32 is driven by the first electric slider 311 and the second electric slider 313 to cut the display screen. After the display screen is cut, high temperature will be generated at the cutting edge. Therefore, the air pump 21 is started, and the air pump 21 blows air into the condensation box 23. The gas enters the second air pipe 24 and the air inlet pipe 428 after condensation in the condensation box 23, and then enters the fixed air pipe 322 through the second air pipe 24, and then enters the gas ring 326 along the telescopic gas rod 325. Finally, the gas is blown to the cutting position through the gas nozzle 327, so as to reduce the temperature in real time to avoid deformation of the cutting surface caused by excessive temperature and untimely cooling, thereby affecting the use of the display screen. The air enters the blowing pipe 425 through the air inlet pipe 428, and then blows to the spaces on both sides of the placing plate 42 through the air heads on both sides of the blowing pipe 425. At this time, the top temperature of the placing plate 42 is reduced, thereby cooling the display screen. Since the wind blocking plate 424 is gradually raised from the middle to both sides, the heat dissipation hole 423 can block part of the passing gas, and the blocked gas moves downward and finally sprays downward through the heat dissipation hole 423, so that the placing plate 42 takes away the heat of the display screen, and the gas blown downward by the heat dissipation hole 423 can blow the inclined surface of the collecting chamber 11, so as to blow the waste downward for easy discharge and blow the dust on the inclined surface of the collecting chamber 11 to avoid excessive dust accumulation. After the cutting is completed, the staff starts the cylinder 42 7. The cylinder 427 pushes the placement plate 42 to move upward, and the placement plate 42 rises along the trajectory of the guide groove 12 by supporting the lifting rod 422. When the placement plate 42 rises, the limit plate 412 with the pull rod 415 rises together, and the pull rod 415 is separated from the gear 417. At this time, there is a large gap between the side of the placement plate 42 close to the pull rod 415 and the collection chamber 11. Therefore, the staff can pull the pull rod 415, and the pull rod 415 drives the driving plate 413 to move, and the driving plate 413 drives the limit plate 412 to move. The limit plate 412 moves to push the display screen on the placement plate 42. When the required display screen is pushed to the edge of the placement plate 42, it stops. At this time, a part of the required display screen is in a suspended state, and the staff uses tools to take the display screen.After the display screen at the edge is taken, the limiting plate 412 continues to move, and the unnecessary waste falls into the collection chamber 11 for collection. The operation is repeated to take the display screens one by one, thereby achieving the collection of the required display screens while unloading the waste, and also avoiding the damage caused by taking the display screen in a state where it is attached to the placement plate 42.
