[0031] For the above example, those skilled in the art should know that when implementing the above technical solution, the first electric slide rail is an existing drive device, and the crossbeam 3 can move horizontally along the Y-axis through the first electric slide rail.

[0032] For the above example, those skilled in the art should know that when implementing the above technical solution, the crossbeam 3 is provided with an electric slider that matches the laser cutting head 5, which enables the laser cutting head 5 to move horizontally along the X-axis on the crossbeam 3, and the laser cutting head 5 itself can move vertically along the Z-axis.

[0033] As will be known to those skilled in the art from the above example, when implementing the above technical solution, the laser cutting head 5 can emit a laser beam, which is used to cut the workpiece sheet.

[0034] Reference Figure 3 , Figure 4 , Figure 5 as well as Figure 6 The material handling mechanism includes a mounting rod 6, on which several cylinders 7 are vertically fixed at equal intervals. The telescopic ends of the cylinders 7 face downwards and are coaxially fixed with air suction cups 8. The cylinders 7 can drive the corresponding air suction cups 8 to perform precise lifting and lowering movements. The air suction cups 8 can adsorb the material and realize the adsorption and gripping operation.

[0035] For the above example, those skilled in the art should know that when implementing the above technical solution, the air suction cup 8 can be connected to an existing air compressor and vacuum generator to achieve the effect of negative pressure adsorption.

[0036] As a technical optimization of this utility model, two mounting seats 9 are symmetrically provided at the bottom of the crossbeam 3, and the mounting rod 6 can be detachably and fixedly connected to the mounting seat 9.

[0038] As a technical optimization of this utility model, the driving mechanism includes a rectangular frame 10. Multiple strip plates 11 are fixed at equal intervals on both sides of the rectangular frame 10. The two ends of each roller 4 are rotatably connected to two strip plates 11 respectively. A driven pulley 12, which is coaxially fixed to the roller 4, is rotatably connected to one side of the strip plate 11. A driving pulley 13, which corresponds to the driven pulley 12, is rotatably connected below the corresponding strip plate 11. The driving pulley 13 and the driven pulley 12 are connected by a first belt drive. The driving pulley 13 is also coaxially fixed to a driving pulley 14. Multiple driving pulleys 14 are connected by a second belt drive. A driving motor 15 is fixed on the rectangular frame 10, and the driving motor 15 is coaxially fixed to a driving pulley 14. When the drive motor 15 starts, it can drive the corresponding drive pulley 14 to rotate precisely. Through the transmission effect of the second belt, multiple drive pulleys 14 rotate synchronously, and at the same time, multiple corresponding drive pulleys 13 also rotate synchronously. Then, the drive pulleys 13 drive the corresponding driven pulleys 12 to rotate through the first belt, so that multiple rollers 4 rotate synchronously and in the same direction.

[0039] As a technical optimization of this utility model, the bottom of the rectangular frame 10 is also provided with a lifting mechanism. The lifting mechanism includes a vertically arranged hydraulic cylinder 16 and two telescopic support rods 17.

[0040] For the above examples, those skilled in the art should know that the electrical devices used in implementing the above technical solutions are all controlled by control modules, that is, by programmable PLC controllers.

[0041] In this invention, the working principle of the device is as follows:

[0042] When using this device, a conveyor belt can be pre-installed in front of the device platform 1 for conveying the sheet material. When the sheet material to be processed is placed in front of the device platform 1, the crossbeam 3 is moved. After the crossbeam 3 moves in front of the device platform 1, the two mounting rods 6 extend outwards from the front of the device platform 1, and the corresponding air suction cups 8 are positioned above the sheet material. Then, the two mounting seats 9 are moved closer together, so that the air suction cups 8 are aligned above the sheet material. The cylinders 7 drive the corresponding air suction cups 8 to move down precisely, and the air suction cups 8 perform the suction and gripping operation of the sheet material. The cylinders 7 drive the corresponding air suction cups 8 to rise, and then the crossbeam 3 is moved to the corresponding position in the middle of the device platform 1. The cylinders 7 control the corresponding air suction cups 8 to descend, and the air suction cups 8 release the sheet material. At this time, the sheet material is placed on the saw blades 2 of the device platform 1, completing a convenient loading operation. Afterwards, the air suction cups 8 rise and reset, and the two mounting rods 6 are separated and moved back to their original positions without affecting the movement of the laser cutting head 5, allowing subsequent laser cutting operations to proceed. Similarly, after cutting, the air suction cup 8 can also be used for unloading.

[0043] When some plates are quite long, and the two mounting rods 6 and the corresponding air suction cups 8 can only adsorb half of the plate area, making effective loading impossible, multiple rollers 4 can be used for loading. First, the hydraulic cylinder 16 is activated, causing the rectangular frame 10 to rise. The rectangular frame 10 then moves the corresponding rollers 4 upwards. During the upward movement, the rollers 4 pass between the two saw blades 2, and their height exceeds the top of the platform 1. Then, through the adsorption and cooperation of the crossbeam 3 and the multiple air suction cups 8, half of the plate is moved onto the rollers 4, and the air suction cups 8 return to their original positions. Next, the drive motor 15 starts, driving the corresponding drive pulleys 14 to rotate precisely. Through the transmission effect of the second belt, the multiple drive pulleys 14 rotate synchronously, and the corresponding multiple drive pulleys 13 also rotate synchronously. The drive pulleys 13 then drive the corresponding driven pulleys 12 via the first belt, ultimately causing the multiple rollers 4 to rotate synchronously and in the same direction. The rotation of multiple rollers 4 enables the conveying of the sheet metal, transporting it to the center of the device platform 1. Subsequently, the rollers 4 are controlled to descend and reset, placing the sheet metal onto several saw blades 2 on the device platform 1, completing a convenient loading operation. Afterward, subsequent laser cutting can be performed. Similarly, after cutting, the air suction cup 8 and multiple rollers 4 can be used for unloading. This device is mainly installed on the crossbeam 3 and at the bottom of the device platform 1, making rational use of space, effectively reducing space occupation, and meeting more flexible production needs.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
