Description

Technical Field

[0001] This invention belongs to the field of laser cutting equipment technology, specifically relating to a laser cutting device for rust-proof and corrosion-resistant safety signs. Background Technology

[0002] Safety signs, as the core carrier of outdoor environmental safety warnings, are mostly made of rust-proof aluminum alloy, 304 / 316 stainless steel or anti-corrosion coated composite materials. They need to withstand harsh working conditions such as long-term exposure to sunlight and rain, humidity, and chemical corrosive media. Therefore, they place extremely high demands on the corrosion resistance, cutting accuracy, waste residue cleaning efficiency and transmission stability of the processing equipment.

[0003] Existing laser cutting equipment is generally a single-worktable structure. A single worktable requires machine downtime for material changes, resulting in significant time commitments for loading and unloading, low production efficiency, and an inability to meet the needs of continuous batch processing. Furthermore, worktable switching is easily obstructed by cutting debris, leading to positioning deviations and mechanical damage. Poor coordination between the switching transmission and cutting systems prevents uninterrupted operation of cutting and loading simultaneously. These problems result in high equipment failure rates, frequent maintenance, and weak continuous production capacity, making them unsuitable for the high-efficiency processing requirements of rust-proof and corrosion-resistant safety signs. Therefore, an improved rust-proof and corrosion-resistant safety sign laser cutting device has been designed. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the prior art, the present invention provides a rust-proof and corrosion-resistant safety sign laser cutting device to solve the problems in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A rust-proof and corrosion-resistant safety sign laser cutting device includes a first machine base, on which a three-axis motion platform is mounted, and the three-axis motion platform is connected to a laser cutter. A second machine connected to the first machine, the second machine having two worktables arranged vertically; It also includes a first transmission mechanism disposed at the connection between the first machine platform and the second machine platform. The first transmission mechanism is connected to the lower worktable, and a second drive mechanism is connected between the two worktables. When the first transmission mechanism drives the lower worktable to move in a first direction, the second drive mechanism drives the upper worktable to move in the opposite direction.

[0006] Furthermore, the first machine includes a machine body, on which a plurality of collection troughs are provided, and a slag receiving box is provided in each collection trough. The bottom of the slag receiving box is connected to a moving wheel, and a pull ring is also provided on the slag receiving box.

[0007] Furthermore, a connecting pipe is provided inside the machine body, the connection port of the connecting pipe is located near the first machine and connected to the air source, and the air outlet of the connecting pipe is located between adjacent collection tanks.

[0008] Furthermore, the first transmission mechanism includes; Power components; The first connector has one side connected to the workbench located below, and the other side is provided with a guide groove; The second connector includes one end slidably connected to the guide groove and the other end connected to the motor assembly.

[0009] Furthermore, the power assembly includes; The first drive motor has two sprockets mounted on the same side of the machine body. One of the sprockets is fixedly connected to the output shaft of the first drive motor. The two sprockets are connected by a chain, and each segment of the chain has a connection socket.

[0010] Furthermore, the second connector includes a base plate, a first connecting shaft is provided on one side of the base plate, a rotating wheel is rotatably connected to the first connecting shaft, the rotating wheel is located in a guide groove, and two connecting posts are provided on the other side of the base plate, the two connecting posts can be inserted into two adjacent connecting holes respectively.

[0011] Furthermore, the machine body is provided with segmented guide rails along the rotation direction of the chain, and the segmented guide rails are provided with grooves for the chain to pass through.

[0012] Furthermore, the second drive mechanism includes; Two second rack plates are distributed vertically, one of which is fixedly connected to the upper surface of the lower worktable, and the other is fixedly connected to the lower surface of the upper worktable. A rotating gear is rotatably connected to a rotating shaft, and two second rack plates are respectively connected to the upper and lower ends of the rotating gear.

[0013] Furthermore, the three-axis motion platform includes a first-direction moving module, a second-direction moving module, and a third-direction moving module. The first-direction moving module is arranged along the length direction of the first machine platform and connected to the second-direction moving module arranged along the width direction of the first machine platform. The laser cutter is connected to the third-direction moving module, which is arranged along the height direction of the first machine platform and connected to the second-direction moving module.

[0014] Furthermore, the workbench includes a frame, the interior of which is connected with a number of spaced-apart partitions, and the exterior of which is provided with a slide.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When the lower worktable moves, the upper worktable moves synchronously in the opposite direction, allowing cutting and loading / unloading to proceed in parallel, eliminating downtime for material changes and significantly improving production efficiency. The transmission is smooth and precise, without jamming: chain-connecting column transmission, wheel-guide groove sliding cooperation, and gear-rack synchronous drive ensure smooth switching and high positioning accuracy.

The second connector includes a base plate 5032; a first connecting shaft is located on one side of the base plate 5032; a rotating wheel 5034 is rotatably connected to the first connecting shaft and is located in a guide groove 5031; and two connecting posts 5033 are located on the other side of the base plate 5032, which can be inserted into two adjacent connecting holes 1071.

The second drive mechanism includes: two second rack plates 504 distributed vertically, one of which is fixedly connected to the upper surface of the lower worktable 500, and the other is fixedly connected to the lower surface of the upper worktable 500; a rotating gear 505, which is rotatably connected to a rotating shaft 506, and the two second rack plates 504 are respectively connected to the upper and lower ends of the rotating gear 505.

[0023] In this embodiment, the three-axis motion platform 300 includes a first-direction moving module 301, a second-direction moving module 302, and a third-direction moving module 303. The first-direction moving module 301 is arranged along the length direction of the first machine platform 100 and connected to the second-direction moving module 302, which is arranged along the width direction of the first machine platform 100. The laser cutter 400 is connected to the third-direction moving module 303, which is arranged along the height direction of the first machine platform 100 and connected to the second-direction moving module 302. The workbench 500 includes a frame 501, with several spaced-apart isolation plates 502 connected inside the frame 501. A slide 507 is provided on the outside of the frame 501. The first machine base 100 serves as the equipment base. Multiple collection troughs 102 are opened on the machine body 101, and a slag receiving box 103 is embedded in the collection trough 102.
