[0012] The concept, specific structure and technical effects of the utility model will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the utility model.

[0013] It should be noted that, in the description of the present invention, terms such as "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0014] See also Figure 1 , 2The figure shows a schematic diagram of a preferred embodiment of the utility model. The utility model is related to a laser cutting machine, which is a laser cutting device and includes a base 1. The base 1 is a horizontal structure, and adjustable support feet 13 are installed at the bottom of the base 1 to facilitate leveling installation. A processing platform 11 with a certain length and two rails 12 respectively located on the left and right sides of the processing platform 11 and extending in parallel along the length direction of the processing platform are provided on the base 1. The processing platform 11 is provided with material tensioning mechanisms 2 at both ends of the length direction. Preferably, the material tensioning mechanism 2 is a feed roller arranged at both ends of the processing platform 11, and the feed roller at at least one end is a top and bottom roller clamping form, and the feed rollers at both ends of the processing platform 11 cooperate to tension the material. This structure realizes automatic feeding, and uses tensioning to finally hold the material to be cut, so that the material is flat on the processing platform 11 to keep it in the cutting area, and can completely cut the preset effect; further, the material tensioning mechanism 2 can also automatically correct the deviation to ensure material transmission, which is conducive to cutting alignment, and then fully utilize the material to avoid waste. The utility model also includes two cutting modules 3, which are installed and moved on the common track of the track 12, and the two cutting modules 3 are independently moved and processed in two areas. The two areas are continuous processing spaces divided by the processing platform in the length direction, so that the two cutting modules 3 can fully cut the effective parts of the material, and can cut different shapes independently. Two products can be cut at one time, which improves production efficiency. The tensioning effect of the material tensioning mechanism 2 also further ensures that the two cutting modules can completely cut the preset shape effect, improve the processing quality and qualified rate.

The two ends of the beam 31 are connected to the rails 12 through sliding trolleys 33 respectively. Each sliding trolley 33 is correspondingly provided with a driving motor 34. The driving motor 34 drives the sliding trolley 33 to reciprocate along the rail 12, and the two driving motors 34 of the same beam 31 work synchronously. Further, the driving motor 34 cooperates with the power box 35 to drive the sliding trolley 33 to move. The driving motor 34 and the power box 35 are both installed on the sliding trolley 33, and the two power boxes 35 of the same beam 31 are connected in series through a synchronous shaft 36. The driving motor 34 and the power box 35 in the figure are connected by a synchronous belt 37. The power box 35 is driven by a gear set to make the rollers on the sliding trolley 33 roll on the track 12, so that the sliding trolley 33 can reciprocate along the track 12. A positioning and limiting connection is also added between the sliding trolley 33 and the track 12 to ensure that the sliding trolley 33 moves on the track 12 without derailing. This structure carries the beam 31 through the sliding trolley 33, and the movement is more stable. Each sliding trolley 33 is correspondingly provided with a driving motor 34, and the two driving motors 34 of the same beam 31 work synchronously to realize dual-drive work, which greatly improves the moving speed of the beam 31 and can better cooperate with the cutting laser head 32 to perform cutting of a set shape. In this embodiment, the driving motor 34 cooperates with the power box 35 to drive the sliding trolley 33 to move, thereby increasing power, and the two power boxes 35 connected to the same beam 31 are connected in series through a synchronization shaft 36, thereby increasing the movement synchronization of the two ends of the beam 31, improving the accuracy and stability of the movement of the beam, thereby greatly improving production quality and efficiency.

[0016] Figure 1 As shown, this embodiment is also combined with the existing online vision technology, and an industrial camera 4 is also provided above the processing platform 11. The industrial camera 4 cooperates with the computer and provides the material position based on the online vision technology and controls the movement of the cutting laser head 32 and the drive motor 34, so that the cutting laser head 32 cuts the set shape, and the positioning and movement are accurate. The movement of the cutting laser head 32 on the beam 31 can be driven by the motor screw mechanism or the motor synchronous belt mechanism, so as to obtain the reciprocating movement of the cutting laser head 32 on the beam 31, and cooperate with the movement of the beam 31 to obtain a composite movement, so as to achieve cutting according to the set shape. The specific working principle of the cutting laser head 32 is the existing technology and will not be repeated here.
