Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, specifically a laser cutting equipment with automatic deviation correction function. Background Technology

[0002] Laser cutting is a process that uses a high-energy-density laser beam to irradiate the surface of a material, causing it to melt, vaporize, or reach its ignition point rapidly. Simultaneously, high-pressure gas is used to blow away the molten material, achieving high-precision cutting. Its core equipment includes a laser generator, optical system, CNC machine tool, and auxiliary gas system. It is widely used in automotive manufacturing, aerospace, electronic component processing, and handicrafts. Compared to traditional cutting methods (such as plasma and waterjet cutting), laser cutting is faster and less polluting, but the equipment cost is higher, making it suitable for high-value-added products.

[0003] When cutting precious metal materials, if there is a positional shift or the cutting head is not positioned accurately, it will cause material waste and increase production costs. Under the current technology, after the workpiece is placed before laser cutting, the positional error may be caused by the uneven placement of the workpiece. It is also necessary to manually control the laser cutting head to move to the initial position of the workpiece for cutting. The low precision of the movement will cause the position of the laser cutting head to deviate, affecting the cutting quality. Summary of the Invention

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Figures 1-4 As shown, the present invention provides a laser cutting equipment with automatic deviation correction function. The laser cutting equipment with automatic deviation correction function includes a work box 1, a platform 2 and a third module slide rail 3 installed inside the work box 1, a detection rod 4 slidably mounted on the third module slide rail 3, a plurality of detection heads 5 mounted at the end of the detection rod 4, a control terminal 10 installed on the work box 1, a deviation correction component 6 installed inside the work box 1, a laser cutting head 9 mounted on the deviation correction component 6, a pre-treatment component 7 and a cleaning component 8 installed inside the work box 1. The pre-treatment component 7 performs pre-treatment cleaning of the workpiece by moving the detection rod 4, and the cleaning component 8 performs pre-cutting cleaning of the laser cutting head 9 by moving the detection rod 4.

[0021] When precious metal workpieces need to be cut, the material is placed on the stage 2, and the third module slide rail 3 is activated to drive the detection rod 4 to slide along the third module slide rail 3. At this time, the detection head will scan and detect the material to be cut and transmit the detection data to the control terminal 10. The control terminal 10 will control the correction component 6 to move to the cutting starting point to accurately cut the precious metal material. This can avoid cutting errors caused by positional deviations when the material is placed, reduce waste of precious metal materials, improve cutting accuracy and reduce production costs. While the detection rod 4 is moving, the pretreatment component 7 can be driven to clean the surface of the object being cut and the cleaning component 8 can be driven to clean the laser cutting head 9 to improve cutting quality.

[0022] The correction component 6 includes an electric telescopic column 601, a first sliding plate 602, a first module slide rail 603, a second sliding plate 604, a second module slide rail 605, and a slide rail slider 606; Two electric telescopic columns 601 are symmetrically installed inside the work box 1. Each of the two electric telescopic columns 601 has a first slide plate 602 installed at its end. Each of the two first slide plates 602 has a first module slide rail 603 installed on it. The two first module slide rails 603 are connected by a second slide plate 604. A second module slide rail 605 is installed on the second slide plate 604. A slide rail slider 606 is slidably installed on the second module slide rail 605. A laser cutting head 9 is installed at the lower end of the slide rail slider 606.

[0023] Based on the detection results, the control terminal 10 first controls the electric telescopic column 601 to lift the first slide plate 602, the first module slide rail 603, the second slide plate 604, the second module slide rail 605, the slide rail slider 606, and the laser cutting head 9 to facilitate correction and positioning. Then, the control terminal 10 controls the movement of the second slide plate 604 along the first module slide rail 603 and the movement of the slide rail slider 606 along the second module slide rail 605 to move the laser cutting head 9 on the horizontal plane, so that the laser cutting head 9 moves to the cutting starting point, achieves precise positioning, corrects possible positional deviations when placing materials, and improves cutting accuracy.

[0024] like Figures 1-6 As shown, the pretreatment assembly 7 includes a mounting frame 701, a first friction roller 702, a second friction roller 703, a first internal gear 705, a second internal gear 706, a gear chain 707, a first external gear 708, and a second external gear 709. A mounting frame 701 is installed on the detection rod 4. A first friction roller 702 and a second friction roller 703 are rotatably mounted on the mounting frame 701. A transmission column 704 is installed at both ends of the first friction roller 702. A first internal gear 705 is installed on the transmission column 704. Two second internal gears 706 are symmetrically installed on the mounting frame 701. The second internal gear 706 and the first internal gear 705 located on the same side of the mounting frame 701 are connected by a gear chain 707. A first external gear 708 is installed on the second internal gear 706. A second external gear 709 is installed at both ends of the second friction roller 703. The second external gear 709 and the first external gear 708 located on the same side of the mounting frame 701 mesh with each other.

[0025] When the detection rod 4 detects the position of the workpiece, it drives the mounting bracket 701 to move synchronously. When the first friction roller 702 contacts the workpiece, it rotates due to friction and wipes the impurities on the workpiece surface. The rotation of the first friction roller 702 drives the first internal gear 705 to rotate synchronously. When the first internal gear 705 rotates, it drives the second internal gear 706 to rotate in the same direction through the gear chain 707. The rotation of the second internal gear 706 drives the first external gear 708 to rotate. The first external gear 708 drives the second external gear 709 to rotate in the opposite direction through gear meshing. When the second external gear 709 rotates, it drives the second friction roller 703 to rotate synchronously, cleaning the workpiece surface again. Since the second friction roller 703 rotates in the opposite direction to the first friction roller 702, the force on the workpiece is balanced and no displacement occurs. Wiping the workpiece surface with the first friction roller 702 and the second friction roller 703 removes tiny impurities, which can prevent impurities from interfering with the focusing and energy distribution of the laser beam, resulting in rough cutting edges, increased burrs, or slag buildup, and can effectively improve laser cutting efficiency. When the first friction roller 702 contacts the workpiece, it will push the workpiece a certain distance due to friction. When the second friction roller 703 contacts the workpiece, the force reaches a state of equilibrium and the workpiece will not move. Since the detection head is located behind the mounting bracket 701, the detection result is the position of the workpiece after the second friction roller 703 contacts the workpiece. The displacement of the workpiece before that does not affect the detection result.

[0026] The preprocessing component 7 also includes a first distance sensor 710. The first distance sensor 710 is mounted on the end of the mounting bracket 701 away from the detection rod 4 and is electrically connected to the detection head.

[0027] The first distance sensor 710 is used to detect the distance to the nearest object under the mounting bracket 701, thereby determining whether the object below the first distance sensor 710 is a workpiece or a platform 2. When the first distance sensor 710 detects that the object below the mounting bracket 701 is a platform 2, it means that the detection is over and the detection head no longer transmits detection data. This is to avoid the workpiece shifting back due to friction when the first friction roller 702 moves to the edge of the workpiece, which would affect the detection result. When the mounting bracket 701 returns to its initial position, the second friction roller 703 will first leave the workpiece, and the workpiece will move again due to friction. At this time, the distance the workpiece moves is the same as the distance the workpiece shifts back due to friction when the first friction roller 702 moves to the edge of the workpiece. Therefore, the position after the workpiece is forced to shift when the first friction roller 702 just contacts it is the result transmitted back to the control terminal 10 by the detection head. By setting the first distance sensor 710, the accuracy of the detection result can be guaranteed, and the cutting quality can be further improved.

[0028] like Figures 1-10 As shown, the cleaning assembly 8 includes a first screw 801, a first screw slider 802, a drive gear 803, a driven gear 804, a first bevel gear 805, a mounting plate 806, a second bevel gear 807, an outer cylinder 808, an inner sleeve 809, a cleaning cone ring 810, a side plate 811, a third bevel gear 812, a second screw 813, an airbag push plate 814, an airbag 815, an air inlet 816, an air outlet 817, a telescopic air pipe 818, a connecting pipe 819, a three-way electrically controlled valve 820, a first branch pipe 821, and an air ring 823. A first screw 801 is rotatably mounted inside the working box 1. A first screw slider 802 is mounted on the mounting bracket 701. The first screw slider 802 is threadedly engaged with the first screw 801. A drive gear 803 is mounted on the first screw 801. A driven gear 804 is rotatably mounted on the working box 1. The drive gear 803 meshes with the driven gear 804. A first bevel gear 805 is mounted on the driven gear 804. A mounting plate 806 is mounted inside the working box 1. A second bevel gear 807 is rotatably mounted on the mounting plate 806. The second bevel gear 807 meshes with the first bevel gear 805. An outer cylinder 808 is mounted on the second bevel gear 807. An inner sleeve 809 is slidably mounted inside the outer cylinder 808. A cleaning cone ring 810 is mounted on the upper end of the inner sleeve 809. A side plate 811 is mounted on the mounting plate 806. A third bevel gear 812 is rotatably mounted on the side plate 811. The third bevel gear 812 meshes with a second bevel gear 807. A second screw 813 is mounted on the second bevel gear 807. An airbag push plate 814 is slidably mounted on the second screw 813. The airbag push plate 814 is connected to the inner wall of the working box 1 on the side away from the airbag push plate 814 through an airbag 815. An air inlet 816 and an air outlet 817 are provided on the air outlet 817. A telescopic air pipe 818 is installed on the telescopic air pipe 818. A connecting pipe 819 is installed on the telescopic air pipe 818. A three-way solenoid valve 820 is installed at the end of the connecting pipe 819. A first branch pipe 821 and a second branch pipe 822 are provided on the three-way solenoid valve 820. An air ring 823 is rotatably mounted on the outer cylinder 808. The air ring 823 connects the first branch pipe 821 and the inner cavity of the outer cylinder 808.

[0029] When not in operation, the laser cutting head 9 is located in the cleaning position, directly above the central column 824. When the detection rod 4 performs displacement detection, the detection rod 4 drives the first screw slider 802 to slide along the first screw 801 via the mounting bracket 701. Due to the threaded engagement, the first screw 801 rotates. The rotation of the first screw 801 drives the drive gear 803 to rotate synchronously. The drive gear 803 drives the driven gear 804 to rotate through gear meshing. When the driven gear 804 rotates, it drives the second bevel gear 807 to rotate through the first bevel gear 805. The second bevel gear 807 drives the third bevel gear 812 to rotate through gear meshing. The third bevel gear 812 drives the second screw 813 to rotate synchronously. Due to the interaction between the airbag push plate 814 and the second screw 813... With threaded engagement, the rotation of the second screw 813 causes the airbag pusher plate 814 to compress the airbag 815. The gas in the airbag 815 flows into the outer cylinder 808 through the air outlet 817, telescopic air pipe 818, connecting pipe 819, first branch pipe 821, and air ring 823. As the air pressure inside the outer cylinder 808 increases, the gas pushes the inner sliding sleeve 809 upward. When the inner sliding sleeve 809 moves upward, it drives the cleaning cone ring 810 to move synchronously. The cleaning cone ring 810 cleans the wall surface of the laser cutting head 9. At the same time, since the rotation of the second bevel gear 807 drives the inner sliding sleeve 809 to rotate synchronously through the outer cylinder 808, the inner sliding sleeve 809 rotates and rises at the same time to clean the laser cutting head 9, which can improve the cleaning effect, extend the service life of the laser cutting head 9, and improve the cutting quality.

[0030] The cleaning assembly 8 also includes a central column 824, a telescopic link 825, a T-shaped bar 826, a slide 827, and a wiping plate 828; A central column 824 is coaxially mounted on the mounting plate 806 with the second bevel gear 807. A telescopic connecting rod 825 is mounted on the second bevel gear 807. A T-shaped rod 826 is mounted at the end of the telescopic connecting rod 825. A sliding groove 827 is provided on the central column 824. The T-shaped rod 826 slides in conjunction with the sliding groove 827. A wiping plate 828 is mounted on the upper end of the T-shaped rod 826.

[0031] When the second bevel gear 807 rotates, it drives the T-shaped rod 826 to rotate synchronously via the telescopic connecting rod 825. Due to the limiting effect of the slide groove 827, the T-shaped rod 826 will rise along the slide groove 827 and eventually stop at the upper end of the slide groove 827 to rotate. The T-shaped rod 826 drives the wiping plate 828 to rise and rotate synchronously. The wiping plate 828 contacts the bottom of the laser cutting head 9 and wipes the lens at the end of the laser cutting head 9 during rotation, which can ensure the cleanliness of the lens and further improve the cutting quality.

[0032] The upper end of the slide groove 827 is annular, the middle section is spiral, and the lower end is an inclined annular shape. The connection between the upper end and the middle section and between the middle section and the lower end is smooth.

[0033] The spiral groove 827 ensures that the wiping plate 828 can rise to a specified height and contact the laser cutting head 9 for easy cleaning. The upper annular groove ensures that the wiping plate 828 can rotate for cleaning at the moving height. The lower annular groove can prevent jamming when the T-shaped rod 826 is reset and can rotate within the lower annular groove.

[0034] The cleaning component 8 also includes a liquid storage tank 829, a first liquid inlet channel 830, a second liquid inlet channel 831, a transfer chamber 832, a one-way valve 833, a liquid inlet push plate 834, a first air passage 835, a second air passage 836, a third liquid inlet channel 837, and a liquid supply pipe 838. A liquid storage tank 829 is mounted on the mounting plate 806. The mounting plate 806 has a first liquid inlet channel 830. The central column 824 has a second liquid inlet channel 831, a third liquid inlet channel 837, and a transfer chamber 832. The second liquid inlet channel 831 is located below the transfer chamber 832, and the third liquid inlet channel 837 is located above the transfer chamber 832. The first liquid inlet channel 830 and the second liquid inlet channel 831 are connected. The second liquid inlet channel 831 is also connected to the transfer chamber 832. A one-way valve 833 is installed at the connection between the liquid channel 831 and the transfer chamber 832. A liquid inlet push plate 834 is slidably installed in the transfer chamber 832. A first air passage 835 is opened on the central column 824, and a second air passage 836 is opened on the mounting plate 806. The first air passage 835 and the second air passage 836 are connected. The second air passage 836 is connected to the second branch pipe 822. A liquid supply pipe 838 is installed below the wiping plate 828. The liquid supply pipe 838 is in sliding fit with the third liquid inlet channel 837.

[0035] When the gas in the airbag 815 enters the connecting pipe 819, some of the gas will enter the area below the liquid inlet push plate 834 through the second branch pipe 822, the second air passage 836, and the first air passage 835. The gas pushes the liquid inlet push plate 834 upward, causing the cleaning fluid in the transfer chamber 832 to wet the wiping plate 828, thus improving the cleaning effect. When the airbag 815 resets and the gas is withdrawn, the liquid inlet push plate 834 moves downward due to negative pressure and draws cleaning fluid from the liquid storage tank 829 through the first liquid inlet channel 830, the second liquid inlet channel 831, and the third liquid inlet channel 837, preparing for the next cleaning.

[0036] The cleaning assembly 8 also includes a second distance sensor 839 and a pressure relief valve 840. The second distance sensor 839 is provided on the inner sliding sleeve 809 and is electrically connected to the three-way solenoid valve 820. The pressure relief valve 840 is installed on the connecting pipe 819.

[0037] The second distance sensor 839 is used to detect the distance between the lower end of the inner sliding sleeve 809 and the lower end of the outer cylinder 808. After the inner sliding sleeve 809 finishes rising, the second distance sensor 839 will send an electrical signal to control the three-way solenoid valve 820 to close the valve port at the first branch pipe 821 and open the valve port at the second branch pipe 822. When the valve port is opened, the gas pushes the cleaning liquid to wet the wiping plate 828. The pressure relief valve 840 is used to detect the air pressure in the connecting pipe 819. When the liquid inlet push plate 834 cannot move upward, the air pressure in the connecting pipe 819 will gradually rise. When the pressure reaches the threshold of the pressure relief valve 840, the gas will overflow from the pressure relief valve 840. The second distance sensor 839 can ensure that the cleaning cone ring 810 can complete the cleaning of the laser cutting head 9. The presence of the pressure relief valve 840 can prevent the internal air pressure of the device from being too high and damaging the equipment, thus extending the service life of the device.

[0038] Working principle of the invention: The detection rod 4 drives the detection head to detect the position of the workpiece, thereby realizing automatic correction of the cutting position of the laser cutting head 9 and avoiding cutting errors caused by placement errors.

[0039] By setting the first friction roller 702 and the second friction roller 703, impurities are cleaned from the workpiece cutting surface to ensure cutting quality. At the same time, the first friction roller 702 and the second friction roller 703 apply frictional forces in opposite directions to the workpiece, which can prevent workpiece displacement errors and ensure the accuracy of the detection results.

[0040] During inspection and pretreatment, the movement of the mounting bracket 701 causes the cleaning cone ring 810 to move upward via the transmission component to clean the wall surface of the laser cutting head 9, and the wiping plate 828 to move upward and rotate to clean the lens below the laser cutting head 9. At the same time, the excess gas pushing the cleaning cone ring 810 upward can allow the cleaning fluid to wet the wiping plate 828, further improving the cleaning effect. Cleaning the laser cutting head 9 can ensure the laser energy transmission efficiency and stable beam quality, further improving the cutting quality.

[0041] When the detection rod 4 is reset and moved, the transmission component reverses, the wiping plate 828 moves down, the airbag 815 resets and draws in air, causing the inner sliding sleeve 809 to move down and the laser cutting head 9 to be exposed, making it easier to move and perform cutting operations. After the components inside the device are reset, the airbag 815 will draw in external air from the air inlet 816 to replenish the required gas.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
