Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a loading device for a laser cutting machine. Background Technique

[0002] Laser cutting is a technology that uses a high-power density laser beam to irradiate the material to be cut, causing the material to quickly melt, vaporize, ablate or reach the ignition point. At the same time, with the help of a high-speed air flow (or auxiliary gas) coaxial with the beam, the molten material is blown away, thereby realizing the cutting of the workpiece. Laser cutting has the following main functions: high-precision cutting, high speed, strong flexibility, suitable for various materials, and environmental protection and pollution-free. Generally speaking, laser cutting technology plays an increasingly important role in the manufacturing industry with its advantages of high precision, high efficiency, strong flexibility, environmental protection and pollution-free. It can not only improve product quality and production efficiency, but also reduce production costs and environmental pollution, and is one of the important directions for the future development of the manufacturing industry.

When the transmission shaft column rotates, it will drive the transmission synchronous pulley to rotate. When the transmission synchronous pulley rotates, it will drive the transmission synchronous belt to rotate and convey. When the transmission synchronous belt rotates and conveys, it will drive the moving frame to move back and forth. When the moving frame moves back and forth, it will drive the limit sliding buckle to move linearly back and forth along the upper end of the limit slide rail, so that the moving frame is linearly moved and limited by the cooperation of the limit sliding buckle and the limit slide rail. When the moving frame moves linearly back and forth, it will synchronously drive the laser cutting raw material adsorbed and lifted by the pneumatic suction cup to move linearly back and forth, thus realizing the function of facilitating the adsorption and lifting of the irregular laser cutting raw material and at the same time, being able to move the adsorbed and lifted laser cutting raw material linearly back and forth for feeding.

A driving motor 6 is fixedly installed on the rear side of the upper end of the main frame 1. The inner transmission shaft part of the driving motor 6 penetrates through the rear side of the upper end of the main frame 1 and is fixedly installed with a transmission shaft column 7. The transmission shaft column 7 is rotatably connected to the front and rear sides of the upper end of the main frame 1 through a rotating shaft respectively. A transmission synchronous pulley 8 is fixedly installed on the outer surface of the transmission shaft column 7. A transmission synchronous belt 9 is connected to the outer end of the transmission synchronous pulley 8 in a transmission manner. A fixed buckle 10 is fixedly installed in the middle of the upper end of the transmission synchronous belt 9, and the fixed buckle 10 is fixedly installed on both sides of the upper end of the moving frame 5;

[0024] A main electric telescopic rod 11 is fixedly installed in the middle of the lower end of the moving frame 5. The telescopic part at the lower end of the main electric telescopic rod 11 is fixedly installed with a feeding plate 12. Two auxiliary electric telescopic rods 13 are fixedly installed on both sides of the lower end of the moving frame 5, and the number of the auxiliary electric telescopic rods 13 is two, symmetrically distributed on both sides of the lower end of the moving frame 5. The telescopic parts at the lower ends of the auxiliary electric telescopic rods 13 are fixedly installed on both sides of the upper end surface of the feeding plate 12. Two first limit sliding rods 19 are fixedly installed on both sides of the upper end of the feeding plate 12, and the upper ends of the first limit sliding rods 19 penetrate and are in fitting and movable connection with both sides of the lower end of the moving frame 5, so as to limit the linear movement of the feeding plate 12 through the first limit sliding rods 19. An L-shaped support plate 14 is fixedly installed on the lower end surface of the feeding plate 12, and the number of the L-shaped support plates 14 is several, symmetrically distributed in sequence on the lower end surface of the feeding plate 12. A limit tube 15 is fixedly installed through the lower side end of the L-shaped support plate 14. A second limit sliding rod 16 is in fitting and movable connection inside the limit tube 15.

[0025] Working principle: When in use, the utility model synchronously controls the opening of the main electric telescopic rod 11 and the auxiliary electric telescopic rod 13. When the main electric telescopic rod 11 and the auxiliary electric telescopic rod 13 are synchronously controlled to open, they will drive the feeding plate 12 to move up and down linearly. When the feeding plate 12 moves down linearly, it will drive the L-shaped support plate 14 to move down linearly. When the L-shaped support plate 14 moves down linearly, it will synchronously drive the air suction cup 17 to move down linearly. When the air suction cup 17 moves down linearly, the raw material to be laser cut can be adsorbed. When the air suction cup 17 adsorbs the raw material to be laser cut, the limit tube 15 will move down linearly along the outer curved surface of the second limit sliding rod 16. When the limit tube 15 moves down linearly, it will push and compress the return spring 18, so that the elastic potential energy generated by the compression of the return spring 18 will reversely push the air suction cup 17 to keep fitting on the upper end of the raw material to be laser cut. When the raw material to be laser cut is irregular, the air suction cup 17 can still keep fitting and adsorbing on the upper end of the raw material to be laser cut. When the feeding plate 12 moves up linearly, it will synchronously drive the limit tube 15 to move up linearly. When the limit tube 15 moves up linearly, through the limitation of the limit ring 20, the second limit sliding rod 16 and the air suction cup 17 can be driven to move up linearly and be lifted, so as to realize the function of facilitating the adsorption and lifting of the irregular laser cutting raw material.

[0026] Meanwhile, by controlling the activation of the drive motor 6, when the drive motor 6 is activated, it will drive the transmission shaft column 7 to rotate. When the transmission shaft column 7 rotates, it will drive the transmission synchronous pulley 8 to rotate. When the transmission synchronous pulley 8 rotates, it will drive the transmission synchronous belt 9 to rotate and convey. When the transmission synchronous belt 9 rotates and conveys, it will drive the moving frame 5 to move back and forth. When the moving frame 5 moves back and forth, it will drive the limit sliding buckle 4 to move linearly back and forth along the upper end of the limit sliding rail 3, so as to limit the linear movement of the moving frame 5 through the cooperation of the limit sliding buckle 4 and the limit sliding rail 3. When the moving frame 5 moves linearly back and forth, it will synchronously drive the pneumatic suction cup 17 to adsorb and lift the laser-cut raw material to move linearly back and forth, so as to realize the function of facilitating the adsorption and lifting of the shaped laser-cut raw material and at the same time, the function of linearly moving the adsorbed and lifted laser-cut raw material back and forth for feeding.
