Description

Technical Field

[0002] A laser cutting machine emits laser from a laser, which is focused into a laser beam with a high power density through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. As the relative position of the beam and the workpiece moves, finally a cut is formed in the material, so as to achieve the purpose of cutting. Laser cutting uses an invisible beam to replace the traditional mechanical knife, with the characteristics of high precision, fast cutting, not limited by cutting pattern limitations, automatic typesetting to save materials, smooth cut, and low processing cost, and will gradually improve or replace the traditional metal cutting process equipment.

[0003] For example, a laser cutting machine is disclosed in Chinese Patent (Publication No.: CN220362127U). Its technical solution includes: a bottom plate, a collection drawer and a screw sleeve. A fixing frame is welded to the front end of the top of the bottom plate. A laser cutter body is installed at the bottom end inside the fixing frame. Support plates are welded to both sides of the bottom plate below the laser cutter body. Bearings are respectively embedded in the two support plates. The inner rings of the two bearings are respectively fixedly installed with lead screws. The screw sleeve is meshed with the lead screw through a screw hole. A fixing sleeve is welded to the top of the screw sleeve. Fixing grooves are respectively opened on both sides inside the fixing sleeve. Fixing blocks are respectively welded to both sides of the collection drawer. An activity hole is opened at the top of the fixing sleeve. A carrier is installed inside the activity hole. This utility model has the advantages of facilitating the staff to process the debris generated by cutting and reducing the cleaning difficulty.

[0004] The above laser cutting machine still has certain deficiencies. When the laser cutter body cuts the workpiece, debris will be generated on the workpiece. After cutting is completed, the workpiece on the top of the fixing sleeve is taken away. However, only through one laser cutting machine, the cutting speed is slow, the cutting efficiency is low, and it is not convenient to move the workpiece, affecting the cutting efficiency. Therefore, a multi-head chain conveyor laser cutting machine is proposed to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 2 , a multi-head chain-feed laser cutting machine in this embodiment includes a chain-feed bed frame 1. A rolling circulating workbench mechanism 4 and multiple crossbeam mechanisms 2 are provided on the chain-feed bed frame 1. A laser cutting head 3 is provided on the crossbeam mechanism 2. The crossbeam mechanism 2 drives the laser cutting head 3 to move. On the front and rear sides of the inner cavity of the chain-feed bed frame 1, drag chain brackets 5 are fixed for supporting the crossbeam mechanism 2. A template 6 is provided on the rolling circulating workbench mechanism 4. The rolling circulating workbench mechanism 4 drives the template 6 to move, facilitating the template 6 to be simultaneously cut by multiple laser cutting heads 3.

[0026] Please refer to Figures 1 to 5 , to prevent collision during movement, the crossbeam mechanism 2 in this embodiment includes a crossbeam frame 205 slidably connected to the upper surface of the chain-feed bed frame 1. Two induction switch frames 204 are fixed on the left and right sides of the crossbeam frame 205. On the left side of the back sides of the two induction switch frames 204 on the left end, two mechanical induction switches 202 are fixed. On the right side of the back sides of the two induction switch frames 204 on the right end, crossbeam induction sheets 203 are fixed. Through the cooperation of the mechanical induction switches 202 and the crossbeam induction sheets 203, the two induction switch frames 204 are prevented from colliding. On the back sides of the left and right two induction switch frames 204, crossbeam hard limit blocks 201 are fixed for providing buffering and protection when the two induction switch frames 204 collide.

[0027] Among them, the crossbeam frame 205 is U-shaped. The laser cutting head 3 is slidably connected to the upper surface of the inner cavity of the crossbeam frame 205. The crossbeam frame 205 and the laser cutting head 3 are both connected to an external controller through data lines for controlling the movement of the crossbeam frame 205 and the laser cutting head 3.

[0028] In addition, the crossbeam induction sheet 203 is L-shaped. A pulley is fixed on the upper surface of the mechanical induction switch 202. During the process of the crossbeam induction sheet 203 and the mechanical induction switch 202 approaching each other, the two crossbeam frames 205 will stop moving through a signal, preventing the induction switch frames 204 on the crossbeam frames 205 from colliding and being damaged.

[0029] In the crossbeam mechanism 2 of this embodiment, in order to prevent the crossbeam frames 205 from colliding with each other, induction switch frames 204 are installed on both the front and rear sides of the crossbeam frame 205, and mechanical induction switches 202 and crossbeam induction sheets 203 are installed on the opposite sides of the two induction switch frames 204 as a first protective measure. A crossbeam hard limit block 201 is installed at the top of the induction switch frame 204 as a second protective measure. When the two induction switch frames 204 are close to each other, the mechanical induction switch 202 and the crossbeam induction sheet 203 will sound an alarm and stop the movement of the crossbeam frame 205. When the two crossbeam frames 205 have not stopped, the two induction switch frames 204 are protected by the crossbeam hard limit block 201.

[0030] See also Figure 2 , Figure 6 and Figure 7 In order to facilitate the movement of the model plate 6, the rolling circulation workbench mechanism 4 in this embodiment includes a driving motor 401 fixed to the back of the chain conveyor bed frame 1, and the output shaft of the driving motor 401 is fixed with a transmission shaft 402, and the transmission shaft 402 is driven to rotate by the driving motor 401. The rolling circulation workbench mechanism 4 also includes a rotating shaft 406 rotatably connected to the front and rear sides of the left side of the inner cavity of the chain conveyor bed frame 1 through a bearing seat, and the outer surfaces of the transmission shaft 402 and the rotating shaft 406 are fixed with a plurality of sprockets 407, and the outer surfaces of the left and right sprockets 407 are connected to the transmission shaft 406. A chain 404 is connected, and the transmission shaft 402 drives the right end sprocket 407 to rotate. The right end sprocket 407 moves the chain 404, and drives the rotating shaft 406 and the left end sprocket 407 to rotate together through the chain 404. The outer surfaces of the multiple chains 404 are fixed with knife strips 403 to increase the friction between the model plate 6 and prevent the model plate 6 from shifting when moving. The rolling circulation workbench mechanism 4 also includes a bed support plate 405 fixed to the front and rear sides of the inner cavity of the chain conveyor bed frame 1, which is used to support the movement of the chain 404 to prevent the chain 404 from falling when moving.

[0031] Among them, the front side of the transmission shaft 402 is driven by the bearing to rotate the chain inside the bed frame 1, which increases the stability of the transmission shaft 402 during rotation. The model plate 6 abuts against the upper surface of the knife bar 403, increasing the friction between the model plate 6 and preventing the model plate 6 from deflecting when moving.

[0032] In addition, the upper surface of the inner cavity of the chain 404 is slidably connected to the upper surface of the bed support plate 405 to support the movement of the chain 404 and prevent the chain 404 from falling when moving.

[0033] In the rolling cycle workbench mechanism 4 of this embodiment, by starting the drive motor 401, the transmission shaft 402 is driven to rotate. Through the cooperation of the transmission shaft 402 and the rotating shaft 406, multiple sprockets 407 are driven to rotate, causing the chain 404 to rotate in a cycle. Through the movement of the chain 404, the template 6 is transported from the tail of the tail bed to the cutting area. Laser cutting is performed by the laser cutting head 3. After cutting is completed, by starting the drive motor 401, the template 6 is transported to the front end for blanking through the chain 404.

[0035] A plurality of crossbeam frames 205 are installed on the chain conveyor bed frame 1. By starting the drive motor 401, the transmission shaft 402 is driven to rotate. Through the cooperation of the transmission shaft 402 and the rotating shaft 406, multiple sprockets 407 are driven to rotate, causing the chain 404 to rotate in a cycle. Through the movement of the chain 404, the template 6 is transported from the tail of the tail bed to the cutting area. Multiple crossbeam frames 205 can operate simultaneously for sheet cutting. The laser cutting head 3 is driven by the crossbeam frame 205 for laser blanking. After cutting is completed, by starting the drive motor 401, the template 6 is transported to the front end for blanking through the chain 404. To prevent the crossbeam frames 205 from colliding with each other, induction switch frames 204 are installed on both the front and rear sides of the crossbeam frames 205. Mechanical induction switches 202 and crossbeam induction sheets 203 are respectively installed on the opposite sides of the two induction switch frames 204. As a first protective measure, a crossbeam hard limit block 201 is installed at the top of the induction switch frame 204 as a second protective measure. When the two induction switch frames 204 approach each other, the mechanical induction switch 202 and the crossbeam induction sheet 203 will issue an alarm and stop the movement of the crossbeam frame 205. When the two crossbeam frames 205 do not stop, the two induction switch frames 204 are protected by the crossbeam hard limit block 201.
