Description

Technical Field

[0001] This utility model belongs to the field of laser cutting technology, specifically relating to a high-efficiency mobile laser cutting device. Background Technology

[0002] The development of laser cutting devices can be traced back to the 1960s, gradually maturing with the invention of the laser. Early CO2 lasers, due to their low power and large size, were only suitable for cutting thin plates in laboratories. After the 1980s, the introduction of CNC technology automated laser cutting, but the equipment remained primarily fixed, with the processing range limited by the size of the worktable. The emergence of fiber lasers in the late 1990s significantly improved energy efficiency, prompting the rise of mobile structures that expand the processing range by moving the cutting head or worktable. However, existing mobile solutions generally suffer from problems such as insufficient rigidity leading to cutting vibration, trajectory deviation caused by synchronization errors in dual-drive systems, and poor adaptability of the clamping mechanism. Therefore, the technical problem that this invention urgently needs to solve is whether a highly efficient mobile laser cutting device can effectively suppress vibration during the cutting process, ensure high-precision cutting quality, and avoid the off-center loading problems easily caused by single-track structures. Summary of the Invention

[0003] In view of this, the present invention discloses a high-efficiency mobile laser cutting device.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The high-efficiency mobile laser cutting device includes a base plate, a first support frame, a second support frame, a fixed base, a clamping assembly, a pushing assembly, a cutting assembly, and a worktable. The first support frame and the second support frame are parallel to each other and vertically mounted on the base plate; the workbench is horizontally mounted between the first support frame and the second support frame. The upper and lower parts of the first support frame are respectively fixed with a first lead screw slide rail and a second lead screw slide rail, and the other ends of the first lead screw slide rail and the second lead screw slide rail are respectively fixed to the upper and lower parts of the second support frame. The clamping assembly is slidably connected to the first lead screw rail and the second lead screw rail via a slider, and is used to clamp the material to be cut; the cutting assembly is installed on the lower surface of the first lead screw rail, and is used to emit a laser beam for cutting; the propulsion assembly is installed on one side of the worktable, and is used to drive the clamping assembly to feed along the length of the worktable, thereby driving the material to be cut to move.

[0005] Furthermore, the worktable is provided with a cross-shaped channel, which consists of a feed channel and a cutting avoidance channel. The feed channel is arranged through the worktable along its length to allow the propulsion component to indirectly push the material. The cutting avoidance channel is located directly below the cutting component to prevent damage to the worktable surface during the cutting process. The cutting avoidance channel is located near the discharge end of the worktable, which is located on the opposite side of the propulsion component.

[0006] Furthermore, the clamping assembly includes: Two first electric telescopic rods are respectively installed opposite to each other on the lower surface of the first lead screw slide rail and the upper surface of the second lead screw slide rail, and the two first electric telescopic rods are respectively located directly above and directly below the feed channel; Two synchronization sensors are connected to the drive modules of the two first electric telescopic rods to detect and control the synchronous telescopic movement of the two first electric telescopic rods. Two first pressure sensors are respectively installed at the clamping ends of the two first electric telescopic rods to monitor the clamping force of the material to be cut in real time.

[0007] Furthermore, the cutting assembly includes an electric slide rail, a second electric telescopic rod, and a laser blade. The electric slide rail is horizontally and vertically mounted on the lower surface of the first lead screw slide rail, and the electric slide rail is located directly above the cutting clearance hole. The electric telescopic rod is vertically and slidably mounted on the electric slide rail, and the laser blade is mounted at the end of the second electric telescopic rod.

[0008] Furthermore, the propulsion assembly includes a fixed base, a third electric telescopic rod, two L-shaped push rods, and a second pressure sensor. The fixed base is mounted on the base plate, and the drive end of the third electric telescopic rod is fixed to the fixed base, with the third electric telescopic rod facing the worktable. The two L-shaped push rods are vertically and symmetrically arranged at the ends of the third electric telescopic rod, forming a U-shaped structure. The third electric telescopic rod and the L-shaped push rods are all on the same straight line as the feed channel, and the second pressure sensor is mounted at the end of at least one of the L-shaped push rods.

[0009] Furthermore, it also includes a linkage adjustment handle, which has a U-shaped structure and its two ends are respectively connected to the drive ends of the two first electric telescopic rods to realize the synchronous horizontal movement of the two first electric telescopic rods.

[0010] Furthermore, it also includes a control box, in which a control module is installed. The control module is connected to the first electric telescopic rod, the second electric telescopic rod, the third electric telescopic rod, the laser knife, the synchronization sensor, the first pressure sensor, and the second pressure sensor, respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The first and second lead screw slide rails without power are fixed to the upper and lower parts of the support frame, respectively, and together with the linkage adjustment handle, they form a dual slide rail synchronous drive module, so that the two first electric telescopic rods in the clamping assembly are always on the same vertical line, making their movement more stable and avoiding the off-center load problem that is easy to occur in the single rail structure. The clamping assembly is slidably connected to the double lead screw slide rail via a slider. Combined with the horizontal drive of the propulsion assembly, it can achieve precise feeding of the material to be cut, reduce manual intervention, and improve cutting efficiency. The cutting assembly is directly fixedly installed on the lower surface of the first lead screw slide rail, optimizing the optical path transmission path, reducing laser energy loss, facilitating maintenance and focal length adjustment, and adapting to the cutting needs of materials of different thicknesses.

[0025] The cutting assembly includes an electric slide rail 14, a second electric telescopic rod 15, and a laser cutter 16.

[0026] The propulsion assembly includes a fixed base 4, a third electric telescopic rod 17, two L-shaped push rods 18, and a second pressure sensor 13. The fixed base 4 is mounted on the base plate 1. The drive end of the third electric telescopic rod 17 is fixed to the fixed base 4, and the third electric telescopic rod 17 is oriented towards the worktable 5.

[0028] The high-efficiency mobile laser cutting device also includes a control box 20, which contains a control module 21.

The control module 21 can be a FANUC Series 30i-B; the electric slide rail 14 can be driven by a ball screw of a THK SR20 linear module; the first electric telescopic rod 10 is a Festo electric telescopic rod; the second electric telescopic rod 15 is an SMC MXQ10 electric linear actuator; the third electric telescopic rod 17 is a Parker 401XR series; the laser cutter 16 includes a fiber laser and a cutting head, the fiber laser is an IPG YLS-6000, and the laser head is a Precitec YRC-30. To ensure cutting safety, a dual-circulation water-cooling system can also be set up, which is existing technology and therefore will not be described in detail in this application; the synchronization sensor 11 can be a Heidenhain LIC 4110 sensor; the first pressure sensor 12 and the second pressure sensor 13 can be Honeywell FSS series.

[0029] In this embodiment, a display screen 22 and operation buttons 23 located on one side of the display screen 22 can also be provided. The display screen 22 is connected to the control module 21, and the operation buttons 23 include a power button, a start button, a stop button, and a reset button. After the material is placed on the worktable 5, the cutting length of the material can be preset on the display screen 22, and the corresponding action control can be performed by clicking the operation buttons 23. The power button controls the power switch of the entire device, the start button is used to start cutting, the stop button is used to control the pause of intermediate cutting, and the reset button is used for manual reset after pausing cutting. In addition, in this application, a numeric keypad can also be provided on one side of the display screen 22 for inputting the preset cutting length value.

[0030] The specific operating steps of this utility model include: The material to be cut is placed horizontally on the workbench 5, with the end of the material away from the push component located directly below the cutting blade. The operator moves the linkage adjustment handle 19 so that the first electric telescopic rod 10 is positioned on the material to be cut near the push component, and the horizontal distance between the first electric telescopic rod 10 and the nearest end of the material to be cut is less than the length to be cut. Click the power button to wake up the laser cutting device; input the preset cutting length value on the display screen 22, click the start button, and the start signal is fed back to the control module 21. The control module 21 starts the first electric telescopic rod 10, and the ends of the two first electric telescopic rods 10 are stretched. During this process, the first electric telescopic rods 10 contact the material to be cut on the worktable 5. When the first pressure sensor 12 detects that the first electric telescopic rods 10 have pressure on the material, it feeds back a signal to the control module 21, and the control module 21 controls the first electric telescopic rods 10 to stop moving. Next, the control module 21 starts the third electric telescopic rod 17, which stretches, causing the L-shaped push rod 18 at its end to move along the feed channel 8. When the end of the L-shaped push rod 18 contacts the second electric telescopic rod 15, the second pressure sensor 13 sends a signal to the control module 21. The control module 21 controls the third electric telescopic rod to continue to stretch, so that after the L-shaped push rod 18 contacts the first electric telescopic rod 10, the third electric telescopic rod 17 stretches again to the preset cutting length value, and then the third electric telescopic rod 17 stops stretching. The second electric telescopic rod 15 is extended until the bottom end of the laser blade 16 contacts the material to be cut. The control module 21 then operates the laser blade 16 to start cutting. During the cutting process, the electric slide rail 14 drives the laser blade 16 to reciprocate once, so that the laser blade 16 can completely cut the material. It should also be noted that in this embodiment, the width of the cutting avoidance channel 9 is no more than 10cm, and the length of the cutting avoidance channel 9 is slightly greater than the length of the electric slide rail 14. The width of the material to be cut is less than the width of the electric slide rail 14 to avoid incomplete cutting. After the cutting is completed, the second electric telescopic rod 15 drives the laser knife 16 to lift up, and then the third electric telescopic rod 17 continues to stretch, indirectly driving the material to move again to the cutting length value. Then the third electric telescopic rod 17 stops, and the second electric telescopic rod 15 stretches to drive the laser knife 16 to contact the material again to perform the cutting operation. In this embodiment, a distance monitoring sensor can be installed on the drive end of the second electric telescopic rod 15 near the electric slide rail 14 and connected to the control module 21. When the distance between the second electric telescopic rod 15 and the electric slide rail 14 is less than 8cm, the distance monitoring sensor will feed back to the control module 21. The control module 21 controls the laser cutting device to reset, first stopping the operation of the electric slide rail 14, the first electric telescopic rod 10, the second electric telescopic rod 15, the third electric telescopic rod 17, and the laser cutter 16; then the first electric telescopic rod 10, the second electric telescopic rod 15, and the third electric telescopic rod 17 retract and return to their original positions, and the electric slide rail 14 drives the laser cutter 16 to move to one side of the electric slide rail 14; then the linkage adjustment handle 19 is manually pushed to avoid affecting the operator's collection of the remaining material on the worktable 5 after cutting.

[0031] In the above cutting operation, a collection box can be set at the discharge end of the worktable 5. After cutting, the material falls from the discharge end of the worktable 5 into the collection box in sequence. As a further optimization of this embodiment, a non-powered conveyor belt can also be set on the worktable. The conveyor belt is embedded on the left and right sides of the worktable at the feed channel, and the upper surface of the conveyor belt is flush with the worktable. This is used to reduce the friction between the material to be cut and the upper surface of the worktable during the process of moving the material to be cut, thereby increasing the service life of the worktable.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
