[0018] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] See appendix Figure 1 To be continued Figure 5 This utility model provides a fully automatic laser cutting machine, including a machine base 1, and a carrier assembly 2, a laser cutting unit 3, a loading and unloading robot 5, a waste collector 6, and a dust collector 7 integrated on the machine base 1. The machine base 1 has a transfer station and a cutting station arranged sequentially along the positive X-axis, and a loading and unloading station arranged on the negative Y-axis side.

[0020] The workflow is as follows: the loading / unloading robot 5 picks up the product from the loading / unloading station and transfers it to the carrier assembly 2. Subsequently, the carrier assembly 2 moves the product from the transfer station to the cutting station. At this time, the laser cutting unit 3 starts to process the product.

[0021] Waste generated during processing falls naturally and is collected promptly by waste collector 6; while fumes generated during cutting are quickly sucked away by fume collector 7. Processed products return to the transfer station, where the loading / unloading robot 5 picks them up and returns them for unified collection. The entire processing requires no manual intervention, achieving fully automated production. This not only improves processing efficiency but also allows for the unified collection and treatment of fumes and waste generated during processing, thus improving the working environment.

[0022] Please see the appendix Figure 1 To be continued Figure 3 The carrier assembly 2 is mounted on the machine base 1 and includes a positioning fixture 21 for fixing the product 10 and an X-axis moving module 22 mounted on the machine base 1 for driving the positioning fixture 21 to move back and forth between the transfer station and the cutting station.

[0023] Specifically, a material discharge port 111 is opened on the table 11 of the machine tool 1 at the cutting station. Waste generated during the processing falls from the material discharge port 111 into the waste collector 6. The X-axis moving module 22 is configured as two sets, which are located on the table 11 and arranged opposite to each other on both sides of the material discharge port 111 along the Y-axis to ensure stable movement of the positioning fixture.

[0024] The transfer plate 23 of the carrier assembly 2 is mounted on the X-axis moving module 22. The two sides of the bottom of the transfer plate 23 are respectively connected to the moving slides X221 of the two sets of X-axis moving modules 22. A through-hole 231 for waste material to fall is opened on the positive X-axis side of the transfer plate 23. The positioning fixture 21 is movably connected to the transfer plate 23 through two sets of drive slide rails 24 arranged along the X-axis. The two sets of drive slide rails 24 are arranged opposite to each other on both sides of the through-hole 231 along the Y-axis. When the positioning fixture moves to the cutting station, the through-hole 231 aligns with the material drop port 111 to collect the waste material.

[0025] Furthermore, to ensure the stability of the product during the cutting process, a pressing mechanism 25 is provided on the positive X-axis side of the transfer plate 23. The pressing mechanism 25 includes a pressing plate 251 located directly above the through opening 231, and two pressing cylinders 252 located on the transfer plate 23 and on both sides of the two sets of drive slide rails 24, for driving the pressing plate 251 to reciprocate along the Z-axis. The pressing plate 251 is provided with a contour opening 2511 corresponding to the position of the product to be cut, so as to ensure that the product is stably positioned and prevent the product from shaking during the processing, which would affect the processing accuracy.

[0026] In other words, by setting a drive slide rail 24 between the positioning fixture 21 and the transfer plate 23, the positioning fixture 21 can move the product along the X-axis to directly below the pressing mechanism, thereby fixing the product. The transfer plate 23 is driven by the X-axis moving module 22 to move along the X-axis, which can ensure that the product adapts to the processing rhythm of the laser cutting unit, thereby realizing the processing of different positions of the product.

[0027] Please see the appendix Figure 1 and attached Figure 4The laser cutting unit 3 is mounted on the positive X-axis side of the machine base 1 via a gantry 4. It includes a generator 31 mounted on a crossbeam 41 of the gantry 4, and a laser cutting head 33 mounted on one side of the crossbeam 41 via a moving module A32 and connected to the generator 31 via an optical path. The moving module A32 includes a Y-axis linear module A321 mounted on the negative X-axis side of the crossbeam 41, and a Z-axis linear module A322 mounted on a moving slide A3211 of the Y-axis linear module A321 via a mounting plate 323. The laser cutting head 33 is connected to the drive slider A3221 of the Z-axis linear module A322 via a bracket 34. This allows the laser cutting head 33 to move along the Y and Z axes and cooperate with a positioning fixture 21 that moves along the X-axis to achieve three-dimensional processing.

[0028] Furthermore, the mounting plate 323 is provided with an air blowing hood 35 with a bottom opening surrounding the laser cutting head 33. One side of the air blowing hood 35 is provided with an air pipe connector 351 connected to an air source. The fumes generated during processing are blocked by the air blowing hood 35 to prevent diffusion. Then, by introducing airflow into the air blowing hood 35, the fumes are moved downwards to prevent them from adhering to the laser cutting head and affecting processing accuracy. At the same time, it is convenient for the fumes to be collected and treated uniformly by the fume collector 7.

[0029] Please see the appendix Figure 1 and attached Figure 5 The loading / unloading robot 5 is mounted on the side of the machine base 1 near the cutting station via a mounting frame 53. It includes a suction cup assembly 51 for picking up products and a moving module B52 for driving the suction cup assembly 51 to move back and forth between the loading / unloading station and the transfer station. The moving module B52 is located on the positive X-axis side of the mounting frame 53 and includes a Y-axis linear module B521 located on the negative X-axis side of the mounting frame 53, and a Z-axis cylinder 522 mounted on a moving slide B5211 of the Y-axis linear module B521 via a vertical plate 5221. The suction cup assembly 51 is mounted on the piston rod of the Z-axis cylinder 522. This allows the suction cup assembly 51 to move along both the Y and Z axes, enabling the products to move back and forth between the loading / unloading station and the transfer station.

[0030] Furthermore, the suction cup assembly 51 includes a linkage plate 511 disposed on the piston rod of the Z-axis cylinder 522 and arranged along the Y-axis, two adjusting plates 512 respectively disposed at both ends of the linkage plate 511, and suction cups 513 disposed on the adjusting plates 512. Each linkage plate 511 has a moving groove 5121 along its X-axis. The four suction cups 513 are arranged in pairs on the two adjusting plates 512. Each suction cup 513 is connected to the adjusting plate 512 through a connector 514 passing through the corresponding moving groove 5121, thereby adjusting the position of the suction cup 513 to meet the needs of transporting products of different specifications.

[0031] Furthermore, the moving module B52 also includes a slide rail 54 on the mounting bracket 53, with the parallel Y-axis linear module B521 mounted on it. The slide rail 54 is positioned below the Y-axis linear module B521. The vertical plate 5221 is connected to the slide rail 54 via a slider 541. The dual-rail structure formed by the Y-axis linear module B521 and the slide rail 54 provides dual guiding support for the laser cutting head, effectively enhancing the stability of the laser cutting head during movement and thus ensuring processing accuracy.

[0032] Understandably, the fully automatic laser cutting machine of this utility model can be placed next to the equipment for producing products or the loading and unloading assembly line. The loading and unloading robot 5 picks up the product to be processed from the loading position and places it in the positioning fixture located in the transfer station. After the product is processed, the loading and unloading robot 5 moves again to pick up the product from the transfer station and place it in the unloading position, thereby realizing fully automated assembly line operation.

[0033] Furthermore, the waste collector 6 is located directly below the cutting station, including a guide hopper 61 located at the material discharge port 111 of the machine platform 1, and a collection bin 62 located at the bottom of the guide hopper 61 for collecting cutting waste. The guide hopper is funnel-shaped to facilitate the introduction of waste into the collection bin 62. The collection bin 62 can be movably placed under the table surface for easy replacement when full.

[0034] Furthermore, the dust collector 7 is located on the X-axis positive side of the cutting station, including a gas collecting hopper 71 located on the table 11 and connected to the X-axis positive side of the guide hopper 61. The air inlet 711 of the gas collecting hopper 71 faces the cutting station, and the side of the gas collecting hopper 71 facing away from the air inlet 711 is connected to an air extraction system to automatically collect the dust generated during the processing.

[0035] In summary, the fully automatic laser cutting machine provided by this utility model achieves automatic loading and unloading of products through a loading and unloading robot, eliminating the need for manual intervention and thus improving production efficiency; the carrier assembly drives the product back and forth between the transfer station and the cutting station, and the pressing mechanism fixes the product to ensure stability during product movement and processing, thereby improving processing accuracy; by integrating a waste collector and a fume collector on the machine base, the waste and fume generated during processing are collected in real time, improving the working environment and extending the service life of the laser cutting head.
