The conveyor belt 9 is arranged horizontally, and its left end is connected to the discharge port of the chasing shearing machine 8, and the right end corresponds to the feed port of the automatic storage warehouse 11. The discharge port of the automatic storage warehouse 11 corresponds to the laser cutting device. The laser cutting device cuts the aluminum veneer and then sorts and transports it through the sorting and conveying device arranged on its right side.

[0021] In order to adapt to the thickness of the aluminum roll 4 and facilitate the leading out of the aluminum, the right end of the material leading platform 5 is axially connected to the leveling machine 6, and a first hydraulic rod 51 inclined to the lower right is provided at the bottom center thereof. Under the action of the first hydraulic rod 51, the material leading platform 5 uses the right end axial connection as a turning point to adjust the upper and lower height position of its left end.

[0022] Since the hardness of aluminum veneer is low, the unwinding speed is fast, and the unwinding and leveling process cannot be interrupted, otherwise it will produce indentations that affect the quality of the sheet. In order to facilitate the storage of aluminum veneer, the length of the sheet that can be leveled at one time should be increased as much as possible. Figure 2As shown, the automatic material storage warehouse 11 includes two front and rear symmetrically arranged brackets 111, and a plurality of mutually parallel rotating shafts are longitudinally arranged between the symmetrically arranged brackets 111. A horizontal conveyor belt 113 is sleeved on the outside of the rotating shaft, and the horizontal conveyor belt 113 and the rotating shaft together form a material storage and feeding unit; bearings are arranged at the front and rear ends of the rotating shaft, and the bearings are fixed by bearing seats 112 symmetrically arranged on the brackets 111, wherein the front end of the rotating shaft passes through the corresponding bearing and extends outside the bearing, and a gear is arranged on the extended end of the rotating shaft, and a driving motor 116 is arranged on the outer side of the gear, and a main transmission gear meshing with the gear is arranged on the transmission shaft of the driving motor 116. The material storage and feeding unit in the automatic material storage warehouse 11 has multiple layers, which are parallel up and down; a layered moving frame 114 is arranged at the front end of the bracket 111, and the layered moving frame 114 is located on the left side of the extended end of the rotating shaft, and a base with an L-shaped structure is arranged on the right side thereof, and a slider is arranged on the left side of the vertical surface of the base, and the slider is engaged with the slide groove arranged on the right side of the layered moving frame 114, and slides up and down in cooperation, and a servo motor 115 is fixedly arranged on the right side of the vertical surface of the base, and the transmission shaft of the servo motor 115 passes through the base and a transmission gear is fixedly arranged on its head, and the transmission gear is meshed with the rack arranged on the right side of the layered moving frame 114, and the servo motor 115 drives the transmission gear to move on the rack, thereby driving the base to move up and down on the layered moving frame 114; a cylinder 117 is fixedly arranged on the horizontal surface of the base, and the drive motor 116 is connected to the cylinder 117, and the cylinder 117 drives the drive motor 116 to move left and right, thereby realizing the mutual clutch between the main transmission gear on the drive motor 116 and the gear at the extended end of the rotating shaft.

[0023] In order to enable automatic loading and feeding of materials on each layer of the multi-layer automatic material storage warehouse 11, symmetrical swinging conveyor belts 10 are provided at the left and right ends of the automatic material storage warehouse 11. The swinging conveyor belt 10 consists of a base and a conveyor belt. The left end of the conveyor belt is connected to the base through an axis 101, and a second hydraulic rod 102 is provided at the bottom of the right end. Under the action of the second hydraulic rod 102, the conveyor belt takes the axis 101 as the turning point, and the second hydraulic rod 102 drives the conveyor belt to adjust the upper and lower angle positions, thereby facilitating the docking of the corresponding storage and feeding units of the automatic material storage warehouse 11.

[0024] In order to facilitate the classification of the cut products after laser cutting of the aluminum veneer, a pre-marking machine 12 capable of marking the back of the aluminum veneer is arranged at the left end of the laser cutting device. It can mark the designated position in advance according to customer needs, and after marking, it is sent to the designated position for laser cutting and unloading, which can ensure the accuracy of the marking position, and marking on the back will not affect the quality of the board surface.

[0025] In order to shorten the time-consuming cost of laser cutting and improve work efficiency, the laser cutting device is composed of a laser cutting machine 13 and a toothed feeding device 14. The laser cutting machine 13 is arranged on the toothed feeding device 14. The laser cutting machine 13 is a double-beam laser cutting machine.

[0026] In order to quickly classify the finished parts after cutting, the sorting and conveying device is composed of a sorting conveyor belt 16 and a sorting robot 15. The sorting robot 15 is arranged on the side of the sorting conveyor belt 16. The sorting robot 15 is used to sort the cut aluminum veneers on the sorting conveyor belt 16.

[0027] Its working principle is as follows: the uncoiler 2 feeds the aluminum veneer material on the aluminum material roll 4 into the leveling machine 6 through the feeding platform, and the aluminum veneer material is flattened under the action of the leveling machine, and then the aluminum veneer material is conveyed to the measuring wheel 7. According to the set length requirement, the measuring wheel 7 feeds the aluminum veneer material into the chasing shearing machine 8 for cutting. Due to the fast uncoiling speed, the uncoiling and leveling process cannot be interrupted. Therefore, the chasing shearing machine 8 will continuously cut the leveled aluminum veneer material under the condition of the length constraint of the measuring wheel 7. The cut aluminum veneer material is sent to the automatic cutting machine 8 through the conveyor belt 9. On the swing conveyor belt 10 on the left side of the automatic storage warehouse 11, according to the material storage situation of the storage and feeding unit on the automatic storage warehouse 11, the swing conveyor belt 10 on the left side of the automatic storage warehouse 11 adjusts the corresponding angle to feed the cut aluminum veneer material into the corresponding storage and feeding unit for aluminum veneer material storage. At the same time, the driving motor 116 on the layered moving frame 114 in front of the automatic storage warehouse 11 moves up and down on the layered moving frame 114 under the action of the servo motor 115 and moves to the set storage and feeding unit. Under the action of the driving motor 116, the storage and feeding unit The horizontal conveyor belt 113 on the unit rotates. Before that, the swing conveyor belt 10 on the right side of the automatic storage warehouse 11 adjusts the corresponding angle. The horizontal conveyor belt 113 rotates to send the aluminum veneer material on its surface to the swing conveyor belt 10 on the right side of the automatic storage warehouse 11. Then the swing conveyor belt 10 sends the aluminum veneer material to the processing pre-marking machine 12 again. The back of the aluminum veneer material is marked by the processing pre-marking machine 12. The marked aluminum veneer material is sent to the rolling tooth feeding device 14. The laser cutting machine 13 on the rolling tooth feeding device 14 cuts the aluminum veneer material. The single plate material is cut, and the laser cutting machine 13 is a double-beam laser cutting machine. The system automatically divides the whole page program into two. The double-beam laser cutting machines run synchronously and do not interfere with each other, which shortens the time-consuming cost of laser cutting and improves work efficiency. After the aluminum single plate material is cut, it becomes a finished part. After the laser cutting is completed, the feedback system repeats the feeding action, and the new aluminum single plate material enters the cutting area. At the same time, the finished parts enter the sorting conveyor belt 16. The sorting robot 15 recognizes the pre-marked mark on the finished parts and starts to automatically pick up the material. After the sorting is completed, the feeding is started to realize the secondary cycle.

[0028] This fully automatic laser processing production line for unwinding and cutting aluminum veneer can be fully automated from raw materials to finished parts. It can be used for various coil raw materials. By using laser cutting, the system can automatically and continuously cut out various workpieces. By directly connecting the coil unwinding to the laser cutting unit, it can save up to 15% of raw materials, achieve better utilization of various raw materials, and achieve minimum material consumption, thereby lowering the cost of workpieces, improving production capacity, stabilizing the operating rhythm, eliminating the time loss of plate loading and unloading, and no molds are required, which greatly improves production efficiency, reduces time and labor costs, and makes operation and management more convenient.

[0029] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
