Description

Technical Field

[0001] This application belongs to the field of laser cutting technology, specifically a laser cutting system. Background Technology

[0002] Laser cutting is an advanced processing technology that uses a high-energy-density laser beam as a "heat source" to precisely cut materials. Its core principle is to generate a high-intensity laser through a laser generator, which is then focused by an optical system to form an extremely fine spot. This causes the material to be locally and instantaneously heated and melted or vaporized, while an auxiliary gas is used to blow away the molten slag, thus achieving the cutting process.

[0003] Currently, when cutting workpieces using a laser cutting system, it is often necessary to first mark the cutting lines or positioning lines by marking them before using a laser cutting robot to cut the workpiece.

[0004] Existing laser cutting systems often involve workers or machines transporting workpieces to a single cutting area for cutting. However, the current single-piece cutting time is approximately 70 seconds, while the handling time of a transport robot is typically only 20 to 40 seconds. Therefore, a significant amount of time is wasted during equipment use, affecting cutting efficiency. Thus, a laser cutting system needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies by designing a laser cutting system that shortens the transport path of the transport robot and uses two cutting workstations to cut the workpiece. This solves the problem of wasted processing time caused by transport time being far less than cutting time.

The rotary table 1 is at least partially within the travel range of the transport robot 4. The finished product conveyor 3 is located to the left of the transport robot 4 and is at least partially within the travel range of the transport robot 4. The number of cutting workstations 2 is set to two sets, which are respectively located in front of and behind the transport robot 4. By setting two sets of cutting workstations 2, it is ensured that a single transport robot 4 can simultaneously transport the workpieces cut by the two sets of cutting workstations 2, thereby saving time. The two sets of cutting workstations 2 are at least partially within the travel range of the transport robot 4.

[0019] In this embodiment, the workpiece to be cut is first transported to the rotary table 1 by other conveying mechanisms. Once the workpiece is on the rotary table 1, it is marked by the built-in structure of the rotary table 1 and then transported to the travel range of the handling robot 4. Subsequently, the handling robot 4 transports it to the cutting workstation 2, where the workpiece is cut.

The mechanical gripper 45 is used to grip the workpiece. The motor 42 drives the mounting block 43 to rotate, and the electric push rod 44 drives the mechanical gripper 45 to move. This allows the mechanical gripper 45 to move the workpiece after gripping it, thereby moving the workpiece from the rotary table 1 to the cutting workstation 2, and then from the cutting workstation 2 to the finished product conveyor 3.

The laser marking machine 15 is used to mark the workpiece. The midpoint of the turntable 13 passes through the edge of the travel range of the mechanical gripper 45. When the workpiece is placed on the turntable 13, it rotates with the turntable 13. When it rotates to the area below the laser marking machine 15, it is marked by the laser marking machine 15. When it continues to rotate with the turntable 13, when it rotates into the gripping range of the mechanical gripper 45, it is clamped by the mechanical gripper 45 and transported to the cutting workstation 2.

[0022] As a preferred embodiment, the finished product conveyor 3 includes a first conveyor belt 31, a second conveyor belt 32, a scrap bin 33, a mounting plate 34, a signal transmitter 35, a signal receiver 36, and a counter 37.

The counter 37 is suspended on the outer wall of the scrap bin 33. The signal receiver 36 is connected to the counter 37. When the signal receiver 36 cannot receive a signal, it transmits a signal to the counter 37, causing the counter 37 to count.

[0023] As a preferred embodiment, the cutting workstation 2 includes a conveyor belt 21, a cutting robot 22, and a clamping assembly 23. The conveyor belts 21 of the two cutting workstations 2 are respectively set on the front and rear sides of the mounting shell 41, with a preset distance between the conveyor belts 21 and the mounting shell 41. The conveyor belts 21 are used to transport waste generated during the cutting process. The cutting robot 22 is set on the side of the conveyor belt 21 away from the mechanical gripper 45. The clamping assembly 23 is set on the side of the conveyor belt 21 close to the mounting shell 41. The clamping assembly 23 is used to clamp the workpiece to ensure that the workpiece will not fall off during cutting.

[0024] As a preferred embodiment, the clamping assembly 23 includes an assembly block 231, a motor 232, a support plate 233, an electric telescopic rod 234, an assembly plate 235, and a control housing 236. The assembly block 231 is positioned on the side of the conveyor belt 21 near the mounting housing 41, with a preset distance between the assembly block 231 and both the conveyor belt 21 and the mounting housing 41. Each clamping assembly 23 contains two assembly blocks 231, positioned on the left and right sides of the conveyor belt 21 respectively.

The end of the support plate 233 near the mounting housing 41 is connected to the electric telescopic rod 234. The fixed connection allows the support plate 233 to rotate when the motor 232 starts. This causes the support plate 233 to switch between the electric telescopic rod 234, the assembly plate 235, and the control shell 236 within the travel range of the handling robot 4 and the cutting range of the cutting workstation 2. This ensures that the transport range required by the handling robot 4 is reduced, enabling it to transport two workpieces within the cutting time of a single workpiece, thus saving time. The output end of the electric telescopic rod 234 is fixedly connected to the assembly plate 235. The assembly plate 235 and the control shell 236 are fixedly connected by bolts. The inner wall of the control shell 236 is provided with a pressure chamber 237. A slide plate 238 is piston-connected to the inner wall of the pressure chamber 237. A clamping rod 239 is fixedly connected to the side of the slide plate 238 away from the assembly plate 235.

[0025] As a preferred method, a KBK crane 5 is also included. The KBK crane 5 is positioned between the assembly block 231 and the mounting shell 41. The lifting range of the KBK crane 5 overlaps with the range of motion of the control shell 236. By setting up the KBK crane 5, it is ensured that when installing and disassembling the control shell 236 and its internal structure, the staff only needs to install and remove the bolts without having to consider its own weight, thus achieving the effect of convenient installation and disassembly.

[0026] As a preferred embodiment, the side of the air chamber 237 away from the motor 232 is composed of multiple cuboid grooves, while the side of the air chamber 237 near the motor 232 is composed of a large cuboid groove that allows multiple cuboids to communicate with each other. The active area of ​​the slide plate 238 is within the cuboid groove on the side of the air chamber 237 away from the motor 232. Each cuboid groove on the side of the air chamber 237 away from the motor 232 is provided with a slide plate 238. By setting the shape of the air chamber 237 and the number of slide plates 238, it is ensured that the clamping rod 239 can clamp workpieces of different shapes by varying the position of the slide plates 238.
