Description

Technical Field

[0001] This invention relates to the field of laser cutting machines, and more specifically, to a laser cutting machine with multi-station feeding. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source, which is focused into a high-power-density beam through an optical path system. This beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. Current laser cutting machines can only feed material from one point and retrieve it from another. Therefore, a worker is always needed to prepare materials during operation. If the laser cutting machine's cutting rate exceeds the worker's feeding rate, the cutting efficiency is slow; if the laser cutting machine's cutting efficiency is lower than the worker's feeding rate, the worker's time is wasted.

[0003] Therefore, how to improve the working efficiency of laser cutting machines is the technical problem that this application aims to solve. Summary of the Invention

[0004] To address the shortcomings of existing technologies, a laser cutting machine with multi-station loading and unloading is provided, which can load and unload materials during cutting, thereby reducing the waiting time of the laser cutting machine and improving its working efficiency.

[0005] To achieve the above objectives, the following technical solution is provided:

[0006] A laser cutting machine with multi-station unloading includes a laser cutting frame, a front material rack, and a rear material rack. The front material rack is located at the front end of the laser cutting frame, and the rear material rack is located at the rear end of the laser cutting frame. The laser cutting frame is used to mount the laser cutting machine.

[0007] A transmission assembly is provided on the laser cutting frame, the front material rack, and the rear material rack. The transmission assembly is equipped with a first material plate and a second material plate, and is used to move the first material plate and the second material plate.

[0008] When the transmission assembly controls the first material plate to move onto the laser cutting frame, the second material plate is located on the front material rack.

[0009] When the transmission assembly controls the second material plate to move onto the laser cutting frame, the first material plate is located on the rear material rack.

[0010] In summary, the above technical solution has the following beneficial effects: The laser cutting machine of this application has two unloading stations. After the sheet metal is placed on the first material plate and the second material plate, it can be moved to the area of ​​the laser cutting frame by the control of the transmission component, so that the laser cutting machine on the laser cutting frame can cut the sheet metal. The area of ​​the first material plate and the second material plate matches the area of ​​the laser cutting frame. Each cut can control one material plate to be cut on the laser cutting frame. When the first material plate is controlled to move to the laser cutting frame to cut the sheet metal, the second material plate is located on the front material rack, and the worker can perform unloading work on the second material plate. After the sheet metal on the first material plate is cut, the first material plate is controlled to move to the rear material rack by the transmission component, and then the second material plate will move to the laser cutting frame, and the sheet metal on the second material plate can be cut, and the worker can perform unloading work on the first material plate. The reciprocating control of the transmission component to move the first material rack and the second material rack allows the laser cutting machine to continuously cut and continuously unload, greatly improving production efficiency.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figure 1 and Figure 2 As shown, a laser cutting machine with multi-station unloading includes a laser cutting frame 10, a front material rack 20, and a rear material rack 30. The front material rack 20 is located at the front end of the laser cutting frame 10, and the rear material rack 30 is located at the rear end of the laser cutting frame 10. The laser cutting frame 10 is used to mount the laser cutting machine. A transmission assembly 40 is commonly mounted on the laser cutting frame 10, the front material rack 20, and the rear material rack 30. A first material plate 50 and a second material plate 60 are mounted on the transmission assembly 40. The transmission assembly 40 is used to move the first material plate 50 and the second material plate 60. When the transmission assembly 40 controls the first material plate 50 to move onto the laser cutting frame 10, the second material plate 60 is located on the front material rack 20. When the transmission assembly 40 controls the second material plate 60 to move onto the laser cutting frame 10, the first material plate 50 is located on the rear material rack 30. The laser cutting machine of this application has two unloading stations. After the sheet metal is placed on the first material plate 50 and the second material plate 60, it can be moved to the area of ​​the laser cutting frame 10 by the control of the transmission component 40, so that the laser cutting machine on the laser cutting frame 10 can cut the sheet metal. The area of ​​the first material plate 50 and the second material plate 60 matches the area of ​​the laser cutting frame 10. Each cut can control one material plate to be cut on the laser cutting frame 10. When the first material plate 50 is controlled to move to the laser cutting frame 10 to cut the sheet metal, the second material plate 60 is located on the front material rack 20, and the worker can perform unloading work on the second material plate 60. After the sheet metal on the first material plate 50 is cut, the first material plate 50 is controlled to move to the rear material rack 30 by the control of the transmission component 40, and then the second material plate 60 will move to the laser cutting frame 10, and the sheet metal on the second material plate 60 can be cut, and the worker can perform unloading work on the first material plate 50. The transmission component 40 reciprocates to control the movement of the first and second material racks, allowing the laser cutting machine to continuously cut and unload materials, greatly improving production efficiency.

[0019] The first material plate 50, the second material plate 60, and the laser cutting frame 10 are all the same length. The length of the front material frame 20 is more than twice the length of the laser cutting frame 10, and the length of the rear material frame 30 is more than the length of the laser cutting frame 10. The length of the front material frame 20 can simultaneously support the first material plate 50 and the second material plate 60. When the first material plate 50 and the second material plate 60 are both on the front material frame 20, they are located at opposite ends of the front material plate. Because the length of the front material frame 20 is more than twice the length of the rear material frame 30, a gap is left between the first material plate 50 and the second material plate 60. This ensures that when the first material plate 50 is on the laser cutting frame 10, the second material plate 60 has sufficient space on the front material frame 20, and when the second material plate 60 is on the laser cutting frame 10, the first material plate 50 has sufficient space on the rear material frame. The distance between the first material plate 50 and the second material plate 60 is equal to the length of the rear material frame 30 exceeding the length of the laser cutting frame 10.

[0020] The transmission assembly 40 includes a motor 41 and a chain 42. The motor 41 is located at the end of the rear material rack 30 near the laser cutting frame 10. The first end of the chain 42 is connected to the motor 41, and the second end extends to the front material rack 20 and is rotatably connected to the front material rack 20. The first material plate 50 and the second material plate 60 are respectively connected to the chain 42, so that the motor 41 can drive the first material plate 50 and the second material plate 60 to move via the chain 42. The length of the chain 42 is three times the length of the laser cutting frame 10, that is, the stroke of the chain 42 is three times the length of the laser cutting frame 10. Because the first material plate 50 and the second material plate 60 can be placed on the front material rack 20 at the same time, and the first material plate 50 is set closer to the rear material rack 30 than the second material plate 60, the motor 41 can move the first material plate 50 from the front material rack 20 to the rear material rack 30 and the second material plate 60 from the front material rack 20 to the laser cutting frame 10 via the chain 42. The first material plate 50 and the second material plate 60 complete the predetermined stroke using the shortest chain 42.

[0021] When the second material plate 60 is located on the front material rack 20 at the end away from the laser cutting frame 10, the second end of the chain 42 is aligned with the end of the second material plate 60 closest to the first material plate 50, and the end of the second material plate 60 closest to the first material plate 50 is connected to the chain 42. To minimize the length of the chain 42, the second material plate 60 is only connected to the chain 42 at one end. This allows the second material plate 60 to move either onto the laser cutting frame 10 or to the end of the front material rack 20 away from the laser cutting frame 10. Preferably, a motor 41 is also provided at the second end of the chain 42. Having motors 41 at both ends of the chain 42 increases its power and makes its operation more stable.

[0022] The first material plate 50 is connected to the chain 42 at the end closest to the second material plate 60. Because the chain 42 extends from the end of the rear material plate closest to the laser cutting frame 10 to the front material rack 20, just enough to align with the position of the second material plate 60, only the end of the first material plate 50 closest to the second material plate 60 is connected to the chain 42 so that the end of the first material plate 50 furthest from the second material plate 60 can move onto the rear material rack 30.

[0023] like Figures 3-5 As shown, the laser cutting frame 10, the front material rack 20, and the rear material rack 30 are all equipped with sliding tracks 70. The first material plate 50 and the second material plate 60 have sliding strips 80 on both sides that slide in conjunction with the sliding tracks 70. The sliding strips 80 are connected to the chain 42. After the sliding strips 80 of the first material plate 50 and the second material plate 60 are inserted into the sliding tracks 70, the sliding strips 80 are connected to the chain 42, allowing the chain 42 to drive the first material plate 50 and the second material plate 60 to slide within the sliding tracks 70. Because there is only one connection point between the first material plate 50 and the second material plate 60 and the chain 42, it is necessary to add sliding tracks 70 and sliding strips 80 to allow the first material plate 50 and the second material plate 60 to slide within the sliding tracks 70, avoiding the up-and-down swaying caused by the chain 42 from affecting the movement trajectory of the first material plate 50 and the second material plate 60.

[0024] Two motors 41 are provided, symmetrically arranged on both sides of the laser cutting frame 10 near the rear material rack 30. Two chains 42 are also provided; the first end of each chain 42 is connected to one of the two motors 41, and the second end of each chain 42 extends to the front material rack 20 and is rotatably connected to it. Both chains 42 are connected to the first material plate 50 and the second material plate 60, allowing the two motors 41 to drive the first material plate 50 and the second material plate 60 to move via the two chains 42. Connecting chains 42 to both sides of the first material plate 50 and the second material plate 60 makes their movement more stable. Preferably, the second end of each chain 42 is also provided with a motor 41, resulting in a total of four motors 41 on both ends of the chains 42. This allows for the transport of heavy materials and makes the chain 42 run more stably.
