Description

[0002] Laser cutting technology is a high-precision and high-efficiency processing method widely used in the processing of materials such as metals, plastics, and ceramics. Its advantages include the ability to cut complex shapes without physical contact during the cutting process, thus avoiding the mechanical stress and heat-affected zone problems that can occur with traditional cutting methods.

[0003] With the continuous development of laser cutting technology, automation and intelligence have become important directions for its future development. In the traditional laser cutting process, material handling remains one of the bottlenecks in the production process, mainly due to low efficiency, high labor intensity, and poor operational safety of manual operation. Therefore, the introduction of automated material handling machines can help improve production efficiency, reduce labor costs, and enhance product quality.

[0004] Existing automated material handling machines typically use robotic arms, chains, or slide rails to transport materials. However, traditional material handling equipment often faces several technical challenges during operation, such as non-parallel workstations, uncoordinated movements, large footprint, and difficult maintenance. These problems not only affect the accuracy and efficiency of automated operations but also increase the operating costs of the equipment.

[0005] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a fully automatic sheet metal handling machine for laser cutting. Utility Model Content

[0028] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 5 As shown, this utility model provides a technical solution for a fully automatic plate loading and unloading machine for laser cutting: including a waiting area 1, a post-processing area 2, a lifting platform plate loading and unloading area 3, a column 4, a lifting mechanism 5, a workstation switching mechanism 6, and a loading and unloading mechanism 7.

[0030] The waiting area 1, the processed area 2, and the lifting platform material handling area 3 are connected by columns 4. Columns 4 are vertically fixed to the equipment base, and a lifting mechanism 5 is connected to their tops. The lifting mechanism 5 is driven by a lifting motor 51, the output of which is connected to a lifting screw 52. A lifting frame 53 is threaded onto the lifting screw 52, ​​and an auxiliary lifting cylinder 54 is located below the lifting frame 53. The output of the auxiliary lifting cylinder 54 is connected to the lifting frame 53 via an auxiliary lifting connecting rod 55. Driven by the lifting motor 51, the lifting screw 52 drives the lifting frame 53 to move vertically, while the auxiliary lifting cylinder 54 and auxiliary lifting connecting rod 55 enhance the stability of the lifting process.

[0031] The workstation switching mechanism 6 is mounted on the lifting frame 53 and includes an adjusting arm 61. A steering motor 63 is mounted on the adjusting arm 61, and the output end of the steering motor 63 is connected to a drive sprocket 64. A steering sprocket 65 is provided at one end of the adjusting arm 61, and a synchronous sprocket 66 is provided at the other end. The steering sprocket 65, the synchronous sprocket 66, and the drive sprocket 64 are connected by a chain 67. A steering shaft 651 is installed in the shaft hole of the steering sprocket 65, and the steering shaft 651 is rotatably connected to the lifting frame 53; a synchronous shaft 661 is installed in the shaft hole of the synchronous sprocket 66, and the bottom end of the synchronous shaft 661 is connected to the pick-and-place mechanism 7. When the steering motor 63 drives the drive sprocket 64, the chain 67 links the steering sprocket 65 and the synchronous sprocket 66, thereby realizing the steering of the adjusting arm 61 and the rotation of the synchronous shaft 661, which in turn drives the pick-and-place mechanism 7 to switch workstations in parallel between multiple workstations.

[0032] The pick-and-place mechanism 7 includes a pick-and-place top seat 71, which is fixed to the end of a synchronous shaft 661. A pick-and-place top frame 72 is connected to the pick-and-place top seat 71. A suction cup lifting cylinder 73 is installed at the corner of the pick-and-place top frame 72, and a vacuum suction cup 74 is connected to its bottom. Driven by the suction cup lifting cylinder 73, the vacuum suction cup 74 can achieve the adsorption and release of the sheet material. In addition, an opening and closing control motor 75 is also installed on the pick-and-place top frame 72, and the output end of the opening and closing control motor 75 is connected to a power shaft 76. The two ends of the power shaft 76 are connected to main sprockets 77, and secondary sprockets 78 are installed on the adjacent sides of the main sprockets 77. The main sprockets 77 and secondary sprockets 78 are driven by chains 79. Fork top frames 80 are set in a staggered manner on the two sets of chains 79, and forks 81 are installed below the fork top frames 80. The fork top frame 80 is also equipped with a top frame guide slide 82, which is slidably connected to the pick-and-place top frame 72 to constrain and support the movement direction of the movable fork (i.e., fork 81). By driving the opening and closing control motor 75, the synchronous opening and closing of the fork 81 can be achieved, thereby realizing precise pick-and-place of the sheet metal.

[0033] An inner tensioning sprocket 68 is provided on the inner side of chain 67, and an outer tensioning sprocket 69 is provided on the outer side, for tensioning chain 67 to ensure the stability and reliability of transmission. A protective cover 62 is also provided on the top of the adjusting arm 61 to protect the transmission components from interference and damage from the external environment. Furthermore, the steering sprocket 65 and the synchronous sprocket 66 have the same diameter, and the steering shaft 651 is arranged parallel to the synchronous shaft 661 to ensure smooth and accurate transmission. The forks 81 consist of two sets of L-shaped fork arms, driven by chain 79 to achieve synchronous opening and closing, meeting the requirements for precise loading and unloading of sheet metal.

[0034] This utility model discloses a fully automatic plate loading and unloading machine for laser cutting. Through the coordinated work of the lifting mechanism 5, the station switching mechanism 6, and the loading and unloading mechanism 7, it realizes efficient and precise switching of the plate between the waiting area 1, the post-processing area 2, and the lifting platform plate loading and unloading area 3, thereby improving the automation level and production efficiency of the laser cutting production line.

[0035] The working principle and usage process of this utility model are as follows: The sheet material to be processed is placed in the processing area 1. The lifting motor 51 of the lifting mechanism 5 is started, and the output end of the lifting motor 51 drives the lifting screw 52 to rotate. Since the lifting screw 52 is threadedly connected to the lifting frame 53, the rotation of the lifting screw 52 will drive the lifting frame 53 to move vertically. At the same time, the auxiliary lifting cylinder 54 and the auxiliary lifting connecting rod 55 enhance the stability of the lifting process, ensuring that the lifting frame 53 can rise smoothly to the designated position.

[0036] Once the lifting frame 53 reaches the designated position, the workstation switching mechanism 6 begins operation. The steering motor 63 starts, and its output drives the drive sprocket 64 to rotate. The drive sprocket 64 is transmitted through the chain 67 to the steering sprocket 65 and the synchronous sprocket 66, thereby driving the adjusting arm 61 to turn. At the same time, the synchronous sprocket 66 drives the synchronous shaft 661 to rotate. The rotation of the synchronous shaft 661 then drives the pick-and-place mechanism 7 to switch between multiple workstations in parallel, achieving precise positioning of the sheet metal to be processed.

[0037] After the pick-and-place mechanism 7 reaches the designated position, the suction cup lifting cylinder 73 is activated, driving the vacuum suction cup 74 to descend and align with the sheet material to be processed. The vacuum suction cup 74 firmly adheres the sheet material to the pick-and-place mechanism 7 through suction. Subsequently, the suction cup lifting cylinder 73 is activated again, driving the vacuum suction cup 74 and the adsorbed sheet material to rise, completing the material pick-up action.

[0038] After the material picking action is completed, the station switching mechanism 6 is restarted, switching the picking and placing mechanism 7 and the adsorbed sheet material to the processing area for laser cutting. After the cutting is completed, the station switching mechanism 6 switches the picking and placing mechanism 7 and the cut sheet material back to the lifting frame 53, and lowers it into the post-processing placement area 2 through the lifting mechanism 5 to complete the material unloading action.

[0039] Throughout the entire operation, the fully automatic sheet metal handling machine for laser cutting of this invention achieves efficient and precise switching of sheet metal between the waiting area 1, the post-processing area 2, and the lifting platform sheet metal handling area 3 through the coordinated operation of the lifting mechanism 5, the station switching mechanism 6, and the handling mechanism 7. Simultaneously, the precise handling of sheet metal is achieved through the cooperation of the suction cup lifting cylinder 73 and the vacuum suction cup, as well as the transmission of the opening and closing control motor 75, the main sprocket 77, the secondary sprocket 78, and the chain 79, thus improving the automation level and production efficiency of the laser cutting production line.
