[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-4 This utility model provides a technical solution: an automatic loading and unloading laser cutting equipment, including a cutting table 1 and a support frame 2 fixedly connected to the top of the cutting table 1. An electric telescopic rod 3 is fixedly installed on the top of the support frame 2 through an opening. The electric telescopic rod 3 is electrically connected to an external power source and controlled by a control switch. A laser cutting mechanism 4 is provided at the telescopic end of the electric telescopic rod 3. A fixing plate 5 is fixedly connected to one side of the front of the cutting table 1. A threaded rod 6 is rotatably connected to one side of the fixing plate 5 through a bearing. A transmission mechanism 8 adapted to the threaded rod 6 is provided at the front of the support frame 2. A threaded sleeve 7 is threadedly connected to the surface of the threaded rod 6. A sliding groove 9 is provided at the front of the cutting table 1. The interior of the sliding groove 9 is slidably connected to the surface of the threaded sleeve 7 through a slider. A push frame 10 is fixedly connected to the top of the surface of the threaded sleeve 7 through a connecting block.

[0022] It should be noted that this device is designed for mass production in factories, performing laser cutting on metal sheets of the same length and cutting position. If it is necessary to laser cut metal sheets of other lengths and cutting positions, the structural position of this device needs to be adjusted.

[0023] Furthermore, to facilitate laser cutting of the sheet metal, the laser cutting mechanism 4 includes a guide rail 41, which is fixedly connected to the telescopic end of the electric telescopic rod 3. A linear motor 42 is mounted on the surface of the guide rail 41. The linear motor 42 is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. A laser cutting head 43 is fixedly mounted on the bottom of the linear motor 42. The laser emitted by the laser cutting head 43 is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0024] Furthermore, to facilitate automatic loading and unloading, the transmission mechanism 8 includes a strip groove 81, which is located at the front of the support frame 2. A sliding block 82 is slidably connected inside the strip groove 81. The rear of the sliding block 82 is fixedly connected to the front of the guide rail 41. A toothed plate 83 is fixedly connected to the front of the sliding block 82. A rotating rod 84 is rotatably connected to the front of the cutting table 1 and located on one side of the groove 9 via a bearing. A circular gear 85 that matches the toothed plate 83 is fixedly connected to the surface of the rotating rod 84. A first bevel gear 86 is fixedly connected to one end of the rotating rod 84, and a second bevel gear 87 that matches the first bevel gear 86 is fixedly connected to one end of the threaded rod 6.

[0025] Furthermore, in order to facilitate the ejection and unloading of the cut sheet metal, several mounting slots 11 are provided on one side of the top of the cutting table 1. A rotating roller 12 is rotatably connected between the front and rear parts of the inner cavity of the mounting slot 11 through a bearing. A collection slot 13 is fixedly installed on one side of the cutting table 1.

[0026] Furthermore, in order to facilitate the extrusion and limiting of the sheet material, limit frames 14 are fixedly connected to both sides of the guide rail 41.

[0027] In use, the electric telescopic rod 3 drives the guide rail 41 to move downward. The guide rail 41 drives the laser cutting head 43 to move downward via the linear motor 42. At the same time, the guide rail 41 drives the two limit frames 14 to move downward, so that the two limit frames 14 squeeze and limit the plate. Then, the linear motor 42 drives the laser cutting head 43 to move back and forth, so that the laser cutting head 43 laser cuts the plate. After the plate is laser cut, the electric telescopic rod 3 drives the guide rail 41 to move upward and reset. The guide rail 41 drives the toothed plate 83 to move upward via the sliding block 82. The toothed plate 83 drives the rotating rod 84 to rotate via the spur gear 85. The rotating rod 84 drives the threaded rod 6 to rotate via the first bevel gear 86 and the second bevel gear 87. The threaded rod 6 drives the pusher frame 10 to move to the right and reset via the threaded sleeve 7.

[0028] The new sheet material is then placed on the left side of the pusher 10 on the cutting table 1. The electric telescopic rod 3 is extended again to drive the guide rail 41 to move downward. The guide rail 41 will drive the pusher 10 to move to the left through the toothed plate 83, the spur gear 85 and the threaded rod 6. The pusher 10 will push the new sheet material to the left to squeeze the cut sheet material. The cut sheet material will fall into the collection groove 13 after passing through multiple rotating rollers 12. The new sheet material will be pushed by the pusher 10 to the bottom of the support frame 2. At the same time, the guide rail 41 will drive the limit frame 14 to squeeze the new sheet material downward again. The above operation is repeated on the new sheet material for laser cutting.
