If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or the sequence of the indicated technical features.

[0033] In the description of the present invention, unless otherwise clearly defined, terms such as "setting", "installation", "connection", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0034] It can be understood that, referring to Figures 1 to 6 , an embodiment of the present invention provides a laser cutting device, including a machine table 100, two carrying platforms 110, a cutting robot 500 and a support assembly 300. The machine table 100 is the installation foundation of the laser cutting device and is usually fixed on the ground of the factory. An outer machine cover 101 is provided on the machine table 100, and the outer machine cover 101 plays a protective role. Since laser is harmful to the human body, and the strong light and flying chips generated during the cutting process will also cause harm to the human body, the outer machine cover 101 is provided to isolate. An observation window is provided on the outer machine cover 101 to penetrate the operating state, and lighting and a monitoring camera are provided inside the outer machine cover 101. In addition, the outer machine cover 101 can also help fix and protect components such as the electrical box, controller and operation panel. An entrance is provided on one side of the outer machine cover 101 as the access channel for workpieces.

[0035] A rotating seat 120 is provided on the machine table 100. The rotating seat 120 is usually driven by a servo motor to rotate and accurately control the rotation angle. Carrying platforms 110 are provided on both sides of the rotating seat 120. A sliding table 400 is provided on the carrying platform 110. The sliding table 400 is used to install a fixture, and the workpiece is fixed on the fixture for convenient laser cutting operation. The sliding table 400 can move in a direction away from or close to the rotating seat 120, so as to adjust the position of the workpiece. During the processing, the sliding table 400 is in the extended state. During loading and unloading, the two carrying platforms 110 are driven by the rotating seat 120 to rotate, and rotating 180° can realize the loading and unloading of the workpiece. During the rotation, the sliding table 400 is in the retracted state.

[0036] A screen assembly 200 is provided on the rotating seat 120. Since strong light will be generated during the laser cutting process, the screen assembly 200 is arranged vertically. The function of the screen assembly 200 is to close the entrance of the outer machine cover 101. The screen assembly 200 can adopt a square tube frame with a metal plate. The screen assembly 200 rotates with the rotating seat 120. Rotating 180° means the screen assembly 200 changes to another direction and still closes the entrance of the outer machine cover 101.

[0037] The cutting robot 500 is installed on the machine table 100 and is located inside the outer machine cover 101. The cutting robot 500 is distributed outside the rotation range of the screen assembly 200 to prevent collision with the workpiece. The cutting robot 500 is usually a multi-axis robotic arm, and a laser cutter is connected to the end to perform laser cutting on the workpiece. Through the multi-directional movement of the multi-axis robotic arm, various shapes can be cut.

[0038] The support components 300 correspond one-to-one with the bearing platforms 110. Each support component 300 includes a base 310 and a telescopic member 320. The base 310 serves as the installation foundation and can be installed on the ground, on a frame, or on other equipment. The telescopic member 320 is fixed to the upper end of the base 310. The telescopic member 320 can be a cylinder, an oil cylinder, an electric push rod, etc., as long as it can meet the requirements of telescoping and providing support force. A ball head support 330 is provided at the upper end of the telescopic member 320. A support plate 120 is provided on the bottom surface of the bearing platform 110. The support plate 120 is located at one end of the bearing platform 110 away from the rotating seat 120. A spherical groove 121 is provided on the support plate 120, and the diameter of the spherical groove 121 is larger than the diameter of the ball head support 330.

[0039] During the processing, the telescopic member 320 of the support component 300 acts, and the ball head support 330 rises into the spherical groove 121 and contacts the support plate 120, thereby supporting the bearing platform 110, avoiding deformation of the bearing platform 110 due to the cantilever structure, preventing errors in the position of the workpiece, and helping to improve the processing accuracy.

[0040] It can be understood that the bearing platform 110 includes a main cross bar 111 fixed to the rotating seat 120. Main longitudinal bars 112 are fixedly connected to both ends of the main cross bar 111. A secondary cross bar 113 is fixedly connected to the other ends of the two main longitudinal bars 112. A connecting rod 114 is also provided at the center of the main cross bar 111 and the secondary cross bar 113. The support plate 120 is located at the connection between the connecting rod 114 and the secondary cross bar 113. Then the support plate 120 is at the farthest end of the cantilever of the bearing platform 110 and is located in the middle, and at the same time provides support for the connecting rod 114, so that the support effect of the support component 300 on the bearing platform 110 is better. The support plate 120 can be connected to the bottom surface of the connecting rod 114, or can be connected to the bottom surface of the secondary cross bar 113, or can be connected to the bottom surfaces of both the connecting rod 114 and the secondary cross bar 113 at the same time. Considering that the weight of the extended slide 400 and the workpiece falls on the end of the bearing platform 110 away from the rotating seat 120, and the bearing platform 110 is a cantilever structure, therefore, setting the position of the support plate 120 at the connection between the connecting rod 114 and the secondary cross bar 113 can stably support the bearing platform 110, prevent the bearing platform 110 from deforming, and further help to accurately position the workpiece and improve the processing accuracy.

[0041] According to some embodiments of the present invention, the bearing platform 110 is provided with two loading plates 115, and the two loading plates 115 are arranged at the lower edges of the opposite sides of the two main longitudinal rods 112. The main longitudinal rods 112 and the loading plates 115 are fixedly connected by a plurality of support plates, and the structure is stable and reliable. A slide rail 116 is provided on the loading plate 115. The slide table 400 includes a square frame composed of two upper longitudinal rods 410 and two upper cross rods 420. The upper longitudinal rods 410 are slidably connected to the slide rail 116 through slide seats 117 to realize the movement of the slide table 400. Among them, the bottom surface of the upper longitudinal rod 410 is lower than the top surface of the main longitudinal rod 112. The two main longitudinal rods 112 are used to limit the slide table 400 to prevent problems such as displacement and falling off of the slide table 400. Moreover, the two loading plates 115 provide symmetric support forces for the slide table 400, and the structure is more stable, which helps to prevent the position change of the slide table 400.

[0042] It can be understood that, in some embodiments of the present invention, the telescopic member 320 is a cylinder, the ball head support 330 is fixed at the end of the piston rod of the cylinder, the ball head support 330 is connected with an upper shield 340, and the upper shield 340 surrounds the cylinder. The upper shield 340 can be used to protect the cylinder to prevent sparks, soot and waste generated by laser cutting from contacting the cylinder, and improve the operation reliability and service life of the cylinder.

[0043] Refer to Figure 5 and Figure 6 , it can be understood that considering that the ball head support 330 moves up and down under the drive of the cylinder, and the upper shield 340 follows the ball head support 330 to move up and down, there will be a protective gap. A lower shield 350 is provided on the base 310, and the lower shield 350 also surrounds the cylinder. Moreover, the upper shield 340 is inserted into the lower shield 350. When the upper shield 340 follows the ball head support 330 to rise, the upper shield 340 and the lower shield 350 remain in the inserted state to fully protect the cylinder. For the convenience of connecting the air pipe of the cylinder, wiring grooves are provided on both the upper shield 340 and the lower shield 350 to facilitate the installation of the air pipe joint.

[0044] For the convenience of installation, a cylinder is provided at the upper end of the upper shield 340. The cylinders are distributed on the outer periphery of the ball head support 330 and are fixed to the ball head support 330 through fasteners. The fasteners can be selected as screws. Loosening the screws can replace and conveniently maintain the cylinder.

[0045] It can be understood that, in order to position and install the cylinder, a positioning groove is provided at the upper end of the base 310, the lower end of the cylinder is located in the positioning groove, and a notch is provided on one side wall of the positioning groove, and the notch extends to the outer wall of the base 310. The notch is provided to facilitate the installation of the air pipe joint and is easy to operate.

[0046] Refer to Figure 7, in some embodiments of the first aspect of the present invention, the support plate 120 is provided with a plurality of through holes, which are circumferentially distributed around the spherical groove 121. Bolts 122 are inserted through the through holes to fix the support plate 120 to the bearing platform 110. The diameter of the through holes is larger than that of the bolts 122. During installation, the position of the support plate 120 can be finely adjusted by using the gap between the inside of the through holes and the bolts 122, so that the ball head support 330 and the spherical groove 121 are centered, improving the stability of the support.

[0047] It can be understood that the shapes of the ball head support 330 and the spherical groove 121 can be the same, or the diameter of the spherical groove 121 can be larger than that of the ball head support 330, facilitating the ball head support 330 to enter the spherical groove 121.

[0048] Referring to Figure 7 , it can also be that a plurality of adjusting blocks 123 are provided on the bottom surface of the bearing platform 110. The plurality of adjusting blocks 123 surround the support plate 120. The adjusting blocks 123 are connected with adjusting rods 124, and the adjusting rods 124 can abut against the support plate 120 to finely adjust the support plate 120. For example, the adjusting rod 124 is a screw rod, and by rotating the adjusting rod 124, the support plate 120 can be pushed, thereby finely adjusting the spherical groove 121. Of course, the adjusting rod 124 can also adopt other structures, such as an electric push rod, to achieve electric adjustment.

The first bellows guard 150, the fixed guard 151, and the second bellows guard 152 form a complete protection structure. During the movement of the slide table 400, it can protect the drive assembly 140 in all directions, preventing the contamination of sparks, smoke, and waste generated by laser cutting, and improving the operation reliability and service life.

[0051] Referring to Figure 10 and Figure 11 , in some embodiments of the present invention, a first dust shield 431 is provided on the upper connecting rod 430. The first dust shield 431 covers the upper connecting rod 430, and two downwardly inclined first inclined plates 432 are provided on both sides of the first dust shield 431. The covered range of the two first inclined plates 432 is much larger than that of the connecting rod 114. The first dust shield 431 is used to block the sparks, smoke, and waste generated by laser cutting, further protecting the drive assembly 300. The first dust shield 431 is fixed to the upper connecting rod 430 by bolts, which is convenient for disassembly and cleaning. The first dust shield 431 is also provided with a first side plate 433. The first side plate 433 is located on the side of the first inclined plate 432 away from the upper connecting rod 430, and the first side plate 433 extends downward.
