Whether it is simple or complex parts, it can be precisely and quickly formed and cut by laser in one time.

[0003] The working platform of the laser cutting machine uses a spike structure to place, move and cut metal plates. Usually, the metal plates are manually pushed to the working platform by workers. During the pushing process, the spikes will scratch the metal plates. When the metal plate is an aluminum plate, the hardness of which is low, the aluminum plate is easily scratched. Prior art "Application No.: 2020222997507" discloses a conveying device for a special laser cutting machine used in the aluminum curtain wall industry, including a frame and a double-layer exchange conveyor table arranged on the frame, the double-layer exchange conveyor table is composed of multiple rows of creeping spikes, and is characterized in that: the frame is also provided with a lifting mechanism that can be lifted and lowered above and below the double-layer exchange conveyor table, the lifting mechanism is composed of multiple rows of support rods arranged at intervals, and a universal roller ball is provided on the top of the support rod, which is used to support the metal plate and still be able to push the metal plate.

[0004] However, when metal plates are laser cut, there is a high probability that the support rod and the universal ball on the top will be cut by the laser, which can easily lead to an increase in the damage rate of the support rod and the universal ball, thereby increasing the maintenance cost and downtime. Summary of the invention

[0031] The present invention is described in detail below in conjunction with specific embodiments.

[0032] In the present invention, when directional words appear, they are used to facilitate the description of the present invention and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present invention.

[0033] In the present invention, unless otherwise specified and limited, when terms such as "disposed on", "connected", and "connected" appear, these terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figures 1 to 9 As shown in the figure, a working platform of a laser cutting machine includes a frame 10, a lifting mechanism 30 and a flip mechanism 40.

[0035] The upper end surface of the rack 10 is provided with a plurality of spike modules 20 arranged at intervals. The lifting mechanism 30 is arranged on the rack 10 and can be lifted and lowered between the intervals between the plurality of spike modules 20 , and is specifically located inside the rack 10 below the spike modules 20 .

[0036] The flip mechanism 40 is arranged on the lifting mechanism 30 in a linkage manner, and can follow the lifting and lowering movement of the lifting mechanism 30 to avoid and cover the top of the lifting mechanism 30 .

[0037] Among them, the lifting mechanism 30 includes a lifting frame 31 and a plurality of support rods 32. The lifting frame 31 is connected to the frame 10 through a guide rail slider so that the lifting frame 31 can be lifted and lowered smoothly. Lifting devices 33 fixedly connected to the frame 10 are vertically arranged on both sides of the lifting frame 31. A plurality of support rods 32 are arranged on the lifting frame 31 at intervals. Each support rod 32 is correspondingly arranged between the intervals between two adjacent spike modules 20. A universal roller 321 is provided on the top of the support rod 32.

[0038] A plurality of guide roller groups 311 are symmetrically arranged on the inner side of the lifting frame 31, and each guide roller group 311 is located between the spacing of two adjacent support rods 32. The flip mechanism 40 includes a plurality of door-type frames 41, and a protective cover 42 for shielding the support rods 32 is arranged on the top of each door-type frame 41. The vertical poles on both sides of each door-type frame 41 are connected in the spacing of each guide roller group 311, and the lower end of the door-type frame 41 is rotatably connected with a synchronous connecting rod 43.

[0039] In the specific implementation, the lifting device 33 is a cylinder, which is used to drive the lifting frame 31 and multiple support rods 32 to move up and down synchronously. A universal ball 321 is provided on the top of the support rod 32, which can also push the plate placed on the support rod 32 after the support rod 32 is raised, thereby facilitating the movement and adjustment of the plate.

[0040] When pushing the plate to feed, the lifting device 33 drives the multiple support rods 32 on the lifting frame 31 to rise vertically. At the same time, when the lifting frame 31 is rising, the door frame 41 in the flip mechanism 40 is driven by the guide roller group 311 to be in an upright state, avoiding the rising support rods 32, so that the top surface height of the support rods 32 is raised to exceed the top surface height of the spike module 20. The worker pushes the plate to the designated position for laser cutting processing through the universal roller 321.

[0041] Before the plate is laser cut, the lifting device 33 drives the multiple support rods 32 on the lifting frame 31 to descend vertically. At the same time, when the lifting frame 31 is descending, the door frame 41 in the flip mechanism 40 is driven by the guide roller group 311 to tilt toward the side of the support rod 32. When it falls to the bottom, the door frame 41 tilts against one side edge of the top surface of the support rod 32, thereby blocking the top of the support rod 32 to prevent the support rod 32 and the universal ball 321 from being cut by the laser.

[0042] In this embodiment, the protective cover 42 is provided with a heat insulating material, and the heat insulating material is arranged in an L shape on the protective cover 42, so as to cover the top of the support rod 32 with the largest area. The heat insulating material on the protective cover 42 can also effectively protect the service life of the protective cover 42.

[0043] In this embodiment, the spike module 20 includes a mounting frame 21 and a spike support bar. Both sides of the mounting frame 21 are connected to the rack 10. Support plates 23 are arranged in the mounting frame 21 at intervals along its length direction. The support plate 23 is provided with slots 24 opened at intervals along its length direction, and the spike support bar is inserted into the slot 24.

[0044] In specific implementation, the spike support strips are conveniently assembled and connected through the slots 24 on the support sheet 23, and the severely worn spike support strips are conveniently disassembled and replaced.

[0045] In a specific implementation, both sides of the mounting frame 21 are detachably connected to the frame 10 via bending connectors, so as to facilitate the disassembly and replacement of the entire spike module 20 and the adjustment of the spacing distance.

[0046] In this embodiment, more than one row of rollers 11 are provided at the edges around the top surface of the frame 10. The length direction of each roller 11 is arranged along the corresponding edge of the frame 10. The top surface of the roller 11 is higher than the top surface of the spike module 20, which can help workers push heavier plates into the top surface of the raised support rod 32.

[0047] Compared with the prior art, the working platform of the laser cutting machine provided by the present invention is used to place the plate for feeding when the lifting mechanism 30 is raised to prevent the spike module 20 from scratching the plate. The flip mechanism 40 follows the lifting mechanism 30 in linkage to avoid the up and down lifting and lowering movement of the lifting mechanism 30. When the lifting mechanism 30 is lowered to perform laser cutting on the plate, the flip mechanism 40 is tilted to block the top of the lifting mechanism 30 to prevent it from being cut by the laser, thereby protecting the support rod 32 and the universal ball 321 on the top of the lifting mechanism 30, thereby extending the service life of the support rod 32 and the universal ball 321, and reducing the damage rate and the maintenance cost of the laser cutting machine.

[0048] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
