When the temperature sensor detects that the temperature of the laser is high, the external cooling system transports cooling water into the shell through the water inlet pipe, the cooling pipe and the water outlet pipe for circulation to cool the air inside the shell. At the same time, the cooling fan blows the cooled air into the shell. Combined with the arrangement of the cooling fins and the heat dissipation groove, the laser is quickly cooled, the heat dissipation effect is better, the service life of the laser is extended, and its cutting accuracy is not affected.

When the required display screen is pushed to the edge of the placement plate, it stops. At this time, a part of the required display screen is in a suspended state, and the staff uses a tool to pick up the display screen. After the display screen at the edge is picked up, the limit plate continues to move, and the unnecessary waste falls into the collection chamber for collection. Repeat the operation, 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 can be avoided.

The two sides of the bottom end of the placement plate are fixedly connected with support lifting rods, and the support lifting rods are slidably connected to the guide grooves. After the cutting is completed, when the placement plate rises, the limiting 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.

[0012] As a preferred embodiment, a cylinder is provided in the middle of the bottom end of the placement plate, and the top and bottom ends of the cylinder are rotatably connected to connecting heads. The connecting head at the top is fixedly connected to the placement plate, and the connecting head at the bottom is fixedly connected to the workbench. When the staff starts the cylinder, the cylinder pushes the placement plate to move upward, and the placement plate rises along the trajectory of the guide groove through the supporting lifting rod.

[0013] As a preferred embodiment, a blowing pipe is fixedly connected to the middle part of the placement plate, and wind blocking plates are fixedly connected at equal intervals on both sides of the blowing pipe inside the placement plate, and the wind blocking plates gradually become higher from the blowing pipe to both sides. Heat dissipation holes are provided in the middle part of the wind blocking plates inside the placement plate, and an air intake pipe is fixedly connected to the bottom end of the placement plate on one side of the cylinder, and the air intake pipe passes through the workbench and is fixedly connected to the workbench. The air pump is started to blow air into the condensation box, and the gas enters the air intake pipe and then enters the blowing pipe. It is then blown into the space on both sides of the placement plate through the air heads on both sides of the blowing pipe. At this time, the temperature at the top end of the placement plate is reduced, thereby cooling the display screen.

[0014] As a preferred embodiment, the air supply assembly includes an air pump, which is fixed on a side of the workbench close to the reset slide, one side of the air pump is fixedly connected to a first air pipe, and an end of the first air pipe away from the air pump is fixedly connected to a condensation box, the condensation box is fixedly connected to the workbench, one side of the condensation box is fixedly connected to the air inlet pipe, the top of the condensation box is fixedly connected to a second air pipe, the top of the second air pipe slides through the bracket and is fixedly connected to the fixed air pipe, the air pump is started, and blows air into the condensation box, the gas enters the second air pipe and the air inlet pipe after condensation in the condensation box, and then enters the fixed air pipe through the second air pipe, and then enters the air ring along the telescopic gas rod, and finally blows the gas toward the cutting position through the gas nozzle.

[0015] As a preferred embodiment, the middle part of the second air pipe is fixedly connected with a fixing ring, and the side of the fixing ring close to the workbench is fixedly connected with a reset block, the reset block is slidably connected to the reset slide groove, and the bottom end of the reset block located inside the reset slide groove is fixedly connected with a reset spring, and the bottom end of the reset spring is fixedly connected to the workbench. The second air pipe is stretched upward as the laser cutter moves, and the second air pipe pulls the fixing ring to move upward, and the fixing ring drives the reset block to slide along the trajectory of the reset slide groove and pulls the reset spring. When the laser cutter slides to one side of the air pump, the reset spring loses its pull and can pull the reset block downward to reset it, and the reset block drives the fixing ring to reset, and the fixed ring drives the second air pipe to reset, thereby preventing the second air pipe from accumulating on the top of the workbench.

[0016] The beneficial effects of the present invention are as follows:

[0017] In the present invention, a worker pulls the pull ring downward, and the pull ring drives the telescopic rod to extend from the fixed tube, and the telescopic rod drives the air ring and the telescopic air rod to move downward, the telescopic air rod gradually stretches, and the air ring drives the air nozzle to move down to the bottom. During cutting, the laser cutter cuts the display screen, and the cut edge of the display screen will generate high temperature after cutting, so the air pump is started to blow air into the condensation box. The gas enters the second air pipe after condensation in the condensation box, and then enters the fixed air pipe through the second air pipe, and then enters the air ring along the telescopic air rod, and finally blows the gas toward the cutting position through the air nozzle, thereby reducing 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.

[0018] When 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, and 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. At this time, a part of the required display screen is in a suspended state, and the staff uses a tool to pick up the display screen. After the display screen at the edge is picked up, the limit plate continues to move, and the unnecessary waste falls into the collection chamber for collection. The operation is repeated, and the display screens can be picked up one by one, thereby achieving the removal of waste while picking up and collecting the required display screen, and also avoiding damage caused by picking up the display screen and the placement plate in a fit state.

[0019] In the present invention, when the display screen is cut, the air pump is started to blow air into the condensation box. The gas enters the air inlet pipe and then enters the air blowing pipe. Then, it is blown to the space on both sides of the placement plate through the air heads on both sides of the air blowing pipe. At this time, the temperature of the top of the placement plate is reduced, thereby cooling the display screen. Since the wind blocking plate is gradually raised from the middle to the two sides, the heat dissipation holes can block part of the passing gas, and the blocked gas moves downward and is finally sprayed downward through the heat dissipation holes, thereby taking away the heat of the display screen from the placement plate. In addition, the gas blown downward by the heat dissipation holes can blow the inclined surface of the collection chamber, thereby blowing the waste downward for easy discharge and blowing the dust on the inclined surface of the collection chamber to avoid excessive dust accumulation.

[0033] In this embodiment, the staff places the display screen on the top of the placement plate 42 and on the side opposite to the limit plate 412, pulls the pull rod 415, and the pull rod 415 drives the top driving plate 413 to move, and the top driving plate 413 drives the limit plate 412 connected thereto to move, and when the top driving plate 413 moves, it can drive the gear 417 to rotate through the rack 414, and the gear 417 drives the bottom driving plate 413 to move, and the bottom driving plate 413 drives the limit plate 412 connected thereto to move. At this time, the two limit plates 413 are in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being in a state of being The positioning plate 412 moves synchronously to limit the display screen, and then the pull ring 324 is pulled downward, and the pull ring 324 drives the telescopic rod 323 to extend from the fixed cylinder 321, and the telescopic rod 323 drives the air ring 326 and the telescopic air rod 325 to move downward, and the telescopic air rod 325 gradually stretches, and the air ring 326 drives the air nozzle 327 to move downward to the bottom end. 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, and the cutting edge of the display screen after cutting is High temperature will be generated, so 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 air ring 326 along the telescopic air rod 325. Finally, the gas is blown toward the cutting position through the air nozzle 327, thereby reducing 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 movement of the laser cutter 32 stretches upward, and the second air pipe 24 pulls the fixed ring 25 to move upward. The fixed ring 25 drives the reset block 26 to slide along the trajectory of the reset slide groove 13 and pulls the reset spring 27. When the laser cutter 32 slides to one side of the air pump 21, the reset spring 27 loses its pull and can pull the reset block 26 downward to reset it. The reset block 26 drives the fixed ring 25 to reset, and the fixed ring 25 drives the second air pipe 24 to reset, thereby preventing the second air pipe 24 from accumulating on the top of the workbench 1.

[0034] like Figure 1 - Figure 8As shown, the clamping and unloading assembly includes a limit block 41, which is fixed to the top of the workbench 1 and located on both sides of the collecting chamber 11. A moving groove 411 is provided on the side and the top of the limit blocks 41 that are close to each other. Both ends of the limit blocks 41 that are close to each other are slidably connected to the limit plate 412, and both ends of the limit plate 412 that are close to each other are fixedly connected to a driving plate 413. The driving plates 413 on the two limit plates 412 are staggered, and one driving plate 413 is slidably connected to the top moving groove 411, and the other driving plate 413 is slidably connected to the moving groove 411 on the opposite side. The side of the driving plates 413 that are close to each other is fixedly connected to a rack 414, and a gear 417 is provided at one end of the two driving plates 413 that are close to each other. The gear 417 meshes with the rack 414, and the end of the top driving plate 413 away from the limit plate 412 is fixedly connected to a pull rod 415, and the two sides of the bottom end of the top limit plate 412 are fixedly connected to a limiting slider 416.

[0035] In this embodiment, after the cutting is completed, the staff starts the cylinder 427, and the cylinder 427 pushes the placement plate 42 to move upward. 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, so 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 limiting plate 412 moves to push the display screen on the placement plate 42, and stops when the required display screen is pushed to the edge of the placement plate 42. At this time, a part of the required display screen is in a suspended state, and the staff uses a tool to pick up the display screen. After the display screen at the edge is picked up, the limiting plate 412 continues to move, and the unnecessary waste falls into the collection chamber 11 for collection. The operation is repeated, and the display screens can be picked up one by one, thereby achieving the removal of waste while collecting the required display screen, and also avoiding damage caused by picking up the display screen in a state where it is in contact with the placement plate 42.

[0036] like Figure 1 - Figure 8As shown, the cooling and blowing assembly includes a placement plate 42, which is slidably connected to the top of the collection chamber 11. Limiting slots 421 are provided on both sides of the top of the placement plate 42. The limiting slots 421 are slidably connected to the limiting slider 416. The two sides of the bottom end of the placement plate 42 are fixedly connected with support lifting rods 422. The support lifting rods 422 are slidably connected to the guide groove 12. A cylinder 427 is provided in the middle of the bottom end of the placement plate 42. The top and bottom ends of the cylinder 427 are rotatably connected to a connector 426. The top connector 426 is fixed to the placement plate 42. Fixed connection, the bottom connector 426 is fixedly connected to the workbench 1, the middle part of the placement plate 42 is fixedly connected to the blowing pipe 425, and the inside of the placement plate 42 is fixedly connected to the wind blocking plates 424 at equal distances on both sides of the blowing pipe 425. The wind blocking plates 424 become higher from the blowing pipe 425 to both sides. The inside of the placement plate 42 is located in the middle of the wind blocking plates 424. Heat dissipation holes 423 are provided. The bottom end of the placement plate 42 is located on one side of the cylinder 427 and is fixedly connected to the air intake pipe 428. The air intake pipe 428 passes through the workbench 1 and is fixedly connected to the workbench 1.

[0037] 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 blowing pipe 425. Then, it is blown to the space on both sides of the placement plate 42 through the air heads on both sides of the 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 the 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, thereby taking away the heat of the display screen from the placement plate 42. In addition, 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.

[0038] Working principle: First, the staff places the display screen on the top of the placement plate 42 and on the side opposite to the limit plate 412, pulls the pull rod 415, and the pull rod 415 drives the top driving plate 413 to move, and the top driving plate 413 drives the limit plate 412 connected thereto to move, and when the top driving plate 413 moves, it can drive the gear 417 to rotate through the rack 414, and the gear 417 drives the bottom driving plate 413 to move, and the bottom driving plate 413 drives the limit plate 412 connected thereto to move, at this time, the two limit plates 412 move synchronously, thereby limiting the display screen, and then pulls the pull ring 324 downward, and the pull ring 324 drives the telescopic rod 323 to extend from the fixed cylinder 321, and the telescopic rod 323 drives the air ring 326 and the telescopic air 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 end. 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. The cutting edge of the display screen will generate high temperature, so the air pump 21 is started to blow 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 toward the cutting position through the gas nozzle 327, thereby reducing the temperature in real time to avoid deformation of the cutting surface caused by excessive temperature and untimely cooling, which affects the use of the display screen. The air enters the blowing pipe 425 through the air inlet pipe 428, and then blows into the space on both sides of the placement plate 42 through the air heads on both sides of the blowing pipe 425. At this time, the temperature of the top of the placement plate 42 is reduced, thereby cooling the display screen. Since the wind blocking plate 424 is set to gradually rise from the middle to the two sides, the heat dissipation hole 423 can block part of the gas passing through, and the blocked gas moves downward and finally sprays downward through the heat dissipation hole 423, thereby taking away the heat of the display screen from the placement plate 42, 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. 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, so 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 and pushes 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 pick up the display screen.After the display screen at the edge is taken away, 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 away the display screens one by one, thereby achieving the goal of removing the waste while taking away the required display screens, and also avoiding the damage caused by taking away the display screen when it is in contact with the placement plate 42.
