Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and more specifically, to a high-precision laser cutting machine with infrared laser ranging capability. Background Technology

[0002] Traditional laser cutting machines typically rely on preset parameters for cutting, lacking the ability to monitor and correct cutting position and distance in real time, potentially leading to low cutting accuracy. Chinese patent CN222471142U discloses a laser cutting machine employing laser measurement and correction. This invention uses two laser rangefinders, located on the cutting assembly and the feeding mechanism respectively, enabling real-time monitoring of the cutting distance and material position to ensure cutting precision. In this patent, the position of the sheet metal after being transferred to the cutting table is difficult to adjust. If the sheet metal is slightly skewed, some material may fall into the blind spot of the laser cutting machine, preventing full processing of the entire workpiece and resulting in material waste.

Feeding belts and transfer rollers are mounted on both sides of the cutting machine tool. An infrared laser measuring instrument is installed at one end of the cutting machine tool near the transfer rollers. Two infrared laser measuring instruments are provided to detect the distance from one side of the sheet material to the measuring instrument. During the initial stage of the sheet material moving to the feeding belt, the two infrared laser measuring instruments detect whether there is any deviation. After the sheet material is properly positioned, the infrared laser measuring instruments detect the moving distance of the sheet material. The feeding belt comprises two independently mounted belt bodies, which control the forward speed on both sides of the sheet material.

A belt motor is provided at one end of the belt roller. The belt roller is sleeved with the belt body. The belt motor drives the belt roller to rotate and controls the movement position of the belt body. The belt bodies jointly support the plate. The two belt bodies are controlled to move by separate belt motors.

[0008] Preferably, the belt body has a mounting hole, and a support member and an anti-slip member are sleeved on the mounting hole. Both the support member and the anti-slip member can rotate around the mounting hole.

[0009] Preferably, the anti-slip component is disposed on the side of the belt body near the inner wall of the cutting machine tool.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] Combination Figures 1-4 This invention relates to a high-precision laser cutting machine with infrared laser ranging capability, comprising a cutting machine tool 1, on which a laser cutting assembly 2 is mounted. A feeding belt 3 is mounted on one side of the cutting machine tool 1 to transport a sheet metal 5 towards the laser cutting assembly 2. A transfer roller 4 is mounted on the other side of the cutting machine tool 1. After being cut by the laser cutting assembly 2, the cut sheet metal 5 is transported away by the transfer roller 4. The feeding belt 3 and transfer roller 4 are respectively arranged on both sides of the laser cutting assembly 2, with a gap between them for the operation of the laser cutting assembly 2. The laser cutting will not damage the feeding belt 3 or the transfer roller 4, and the cutting debris can fall directly onto the base plate of the cutting machine tool 1 for collection. An infrared laser measuring instrument 11 is installed at one end of the cutting machine 1 near the feed roller 4. There are two infrared laser measuring instruments 11, which are used to detect the distance from one side of the plate 5 to the infrared laser measuring instrument 11. When the distances detected by the two infrared laser measuring instruments 11 are the same, it means that the plate 5 has not been deviated. Conversely, when the distances detected by the two infrared laser measuring instruments 11 are not the same, it means that the side of the plate 5 moving towards the laser cutting assembly 2 is not aligned and needs to be adjusted. In the initial stage when the plate 5 moves to the feed belt 3, the two infrared laser measuring instruments 11 are used to detect whether there is any deviation. After the plate 5 is properly positioned, the infrared laser measuring instruments 11 are used to detect the moving distance of the plate 5, set the cutting distance of the plate 5, calculate the cutting position of the plate 5 based on the distance from the edge of the plate 5 to the infrared laser measuring instrument 11, and then use the laser cutting assembly 2 to cut.

[0021] The laser cutting assembly 2 includes a moving guide rail 21 and a laser cutting head 22. The moving guide rail 21 controls the movement of the laser cutting head 22 through a lead screw and a drive motor, thereby changing the cutting position of the laser cutting head 22.

[0022] The feeding belt 3 includes a belt roller 31, a belt motor 32, a belt body 33, and an intermediate support 34. Belt rollers 31 are symmetrically arranged on both sides of the intermediate support 34. A belt motor 32 is provided at one end of the belt roller 31. The belt motor 32 drives the belt roller 31 to rotate and controls the movement position of the belt body 33. There are two belt bodies 33. The belt bodies 33 jointly support the plate 5. The movement of the two belt bodies 33 is controlled by a separate belt motor 32. The movement speed of the two belt bodies 33 can be the same or different.

[0023] The belt body 33 has two rows of mounting holes 331. Support members 332 and anti-slip members 333 are fitted onto the mounting holes 331. Both support members 332 and anti-slip members 333 can rotate around the mounting holes 331. Specifically, the anti-slip member 333 is located on the side of the belt body 33 near the inner wall of the cutting machine tool 1. Both the anti-slip member 333 and the support member 332 are provided with an upper limit plate 3321 and a lower limit plate 3322. The lower limit plate 3322 is embedded in the mounting hole 331, and the upper limit plate 3321 is in contact with the belt body 33. The upper limit plate 3321 of the anti-slip member 333 is provided with an anti-slip pad 3331. During operation, the anti-slip member 333 and the support member 332 support the plate 5 at the same time. When the plate 5 is tilted, the belt motor 32 controls the belt bodies 33 on both sides to move at different speeds, so that the plate 5 on the "lagging" side can "catch up".

[0024] Specifically, when the anti-slip mat 3331 contacts the plate 5, the friction between them is relatively large, and the plate 5 cannot move on the anti-slip mat 3331. However, the top of the support member 332 is not restricted, and the support area of ​​the plate 5 is increased by the support member 332. When the plate 5 is tilted, the infrared laser measuring instrument 11 detects that the belt motor 32 on the side with a larger distance increases speed, and controls the belt body 33 to drive one side of the plate 5 to increase speed through the support member 332 and the anti-slip member 333. At this time, under the restriction of the anti-slip members 333 on both sides, the plate 5 overcomes the inertia of sliding and maintains the same moving speed as the belt bodies 33 on both sides. The plate 5 rotates until the infrared laser measuring instrument 11 detects that the distance on both sides is the same, thus eliminating the tilt of the plate 5.

[0025] One end of the conveyor roller 4 is meshed with a gear 41. One of the conveyor rollers 4 is connected to a roller motor 42. The roller motor 42 is set on the outer wall of the cutting machine tool 1. The roller motor 42 controls all the conveyor rollers 4 to move in the same direction to receive the cut plate 5. The conveyor rollers 4 drive the separation of the debris from the cut plate 5.

[0026] Working process: In the initial stage when the sheet material 5 enters the feeding belt 3, two infrared laser measuring instruments 11 detect the distance from both sides of the sheet material 5 to the rangefinder. If the distances are different, it indicates that the sheet material 5 has been skewed. At this time, the control system adjusts the moving speed of the two belt bodies 33 according to the measured data, so that one side of the sheet material 5 accelerates or decelerates to correct the skew, until the distances on both sides are equal. After the sheet material 5 is corrected, it will continue to move along the feeding belt 3 towards the laser cutting assembly 2. During this process, the infrared laser measuring instruments 11 continuously monitor the position and moving distance of the sheet material 5 to ensure accuracy. The laser cutting head 22 moves along the moving guide rail 21 according to the preset program when the plate 5 reaches the designated position. It is precisely positioned by the lead screw and drive motor. The laser cutting head 22 emits a high-energy laser beam to cut the plate 5. Since there is a gap between the cutting area and the feeding belt 3 and the transfer roller 4, the cutting debris falls onto the base plate of the cutting machine tool 1. The plate 5 after cutting is received by the transfer roller 4 and transported away from the cutting machine tool 1. The rotation of the transfer roller 4 helps to separate the debris generated during the cutting process and prevents them from adhering to the surface of the finished product.
