Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting production, and in particular to an automated laser cutting production system and production method. Background Art

[0002] A laser cutting machine is a machine that focuses the laser light emitted from a laser into a high-power density laser beam through an optical path system. When the laser beam hits the surface of the workpiece, it releases a large amount of energy to make the workpiece reach its melting point or boiling point, causing it to quickly melt, vaporize, ablate, or reach its ignition point. At the same time, with the help of high-pressure gas coaxial with the beam, the molten or vaporized metal is blown away to achieve the purpose of cutting or engraving. Due to the high precision and fast cutting speed of the laser cutting machine, it is not limited to the cutting pattern, automatic typesetting saves materials, and has high cutting accuracy, fast cutting speed, smooth cutting surface, low processing cost, and is not easy to damage the workpiece. In particular, it reduces the cost of subsequent process processing. The advantages are particularly obvious in large-scale production. Therefore, in recent years, it has been recognized and used by more and more industries and enterprises, and there is a trend of gradually improving or replacing traditional metal cutting process equipment.

[0003] During the use of the laser cutting machine, the operator needs to place the workpiece to be processed by the laser cutting machine on the specified position on the laser cutting machine workbench, and then the laser cutting machine workbench automatically transports the workpiece to be processed to the cutting machine processing area for laser processing. After the workpiece is processed, the laser cutting machine workbench will be transported out of the processing area, and then the operator will place the workpiece from the laser cutting machine workbench to the specified position on the ground, which is relatively inefficient.

[0004] The Chinese invention patent with announcement number CN112192049A discloses a thick plate material laser cutting production line, including a three-dimensional plate material warehouse, a front discharge trolley, a laser processing material area and a roller sorting platform arranged in sequence from front to back, one end of the laser processing material area is connected to a laser cutting machine; the laser processing material area includes a cutting workbench that can move toward the laser cutting machine; a frame is provided on the outside of the front discharge trolley, the laser processing material area and the roller sorting platform, and two mutually symmetrical upper guide rails are longitudinally provided on the top of the frame, and a movable beam is provided between the two upper guide rails, a Z rod is provided on the front of the movable beam, and a loading and unloading robot is provided at the bottom of the Z rod.

[0005] Although this invention reduces the manual intervention in stacking, material selection, unloading and cutting, once it is put into large-scale production, the output of such a production line is too small, and the combination of several such production lines wastes too much factory space. It is also difficult to reasonably schedule production to fully utilize the production capacity of each laser cutting machine, and it is not suitable for the needs of modern production for high efficiency and automation.

[0079] The present invention provides a laser cutting automated production system that provides a multifunctional fully automatic laser cutting production line that extracts the material to be cut, passes it through a shot blasting machine, automatically performs the laser cutting task, optimizes production scheduling, cyclically loads and unloads materials, processes in an orderly manner multiple laser cutting devices 23, intelligently sorts small, medium and large parts, and intelligently handles waste. Medium and large materials can optionally pass through a leveling machine 371, thereby meeting the needs of high-efficiency automation of laser cutting production.

[0080] Example 2:

[0081] like Figure 9 、 Figure 10 As shown, this embodiment relates to an automated laser cutting production method, comprising the following steps:

[0082] Step A: The material to be cut is taken out from the storage warehouse by the automatic material picking device and then aligned on the centering station after passing through the shot blasting machine. If the laser cutting operation can be performed immediately, it is directly transported to the mobile cutting platform located on the pre-loading device. If there is no production schedule for the time being, it is put into the buffer warehouse for standby use. After there is a production schedule, the material to be cut is transported from the buffer warehouse to the mobile cutting platform located on the pre-loading device by the automatic material picking device.

[0083] Step B: The material to be cut placed on the mobile cutting platform is coded and transported to the multi-channel cycle loading and unloading laser cutting equipment group through the preparatory loading device for plate cutting and cycle loading, and the multiple laser cutting devices are processed in an orderly manner.

[0084] Step B specifically includes the following steps:

[0085] a. Find the laser cutting device that is not performing laser cutting operations and find the corresponding row and column numbers. Then determine whether the laser cutting device between the laser cutting device and the transport loading device in the length direction is currently performing laser cutting operations. If there is a laser cutting device that is currently performing laser cutting operations, transport it via the first height. If there is no laser cutting device that is currently performing laser cutting operations, transport it via either the first height or the second height.

[0086] After determining the transport height, the mobile cutting platform on which the material to be cut is placed will be adjusted in height through the preparatory loading device and transferred to the corresponding moving loading device. Then the moving loading device will move the mobile cutting platform on which the material to be cut is placed to the column where the laser cutting device that has not performed laser cutting operation is located, and move the mobile cutting platform on which the material to be cut is placed in the direction close to the laser cutting equipment, and enter the interior of the shell of the laser cutting device at the first height or the second height.

[0087] b. The lifting frame located below the material to be cut is raised upward, and the mobile cutting platform on which the material to be cut is placed is lifted to a third height, and the laser cutting operation is performed through the laser cutting assembly.

[0088] c. After the laser cutting operation is completed, it is first determined whether a laser cutting device is currently performing a laser cutting operation between the laser cutting device and the moving blanking device in the length direction of the laser cutting device after the laser cutting operation is completed. If a laser cutting device is currently performing a laser cutting operation, the lifting frame is lowered to the first height for transportation. If no laser cutting device is currently performing a laser cutting operation, the lifting frame is lowered to the first height or the second height for transportation. The mobile cutting platform with the laser-cut material placed thereon is moved toward the moving blanking device, and the moving blanking device receives the mobile cutting platform with the laser-cut material placed thereon at the position of the column where the laser cutting device that has completed the laser cutting operation is located.

[0089] Step C: The mobile cutting platform of the laser-cut material is transported to the sorting and conveying channel through the moving unloading device. If there is small material after the small material sorting device, it is placed at the input end of the small material conveyor belt through the small material robotic arm and transported to the output end and placed in the small material basket through the small material robotic arm.

[0090] The mobile cutting platform continues along the sorting and conveying channel through the medium-sized material sorting device. If there is medium-sized material, it will pass through the medium-sized material sorting track and the mobile medium-sized material track to move the grabbing mechanism above the medium-sized material, drop and grab the medium-sized material. If leveling is not required, it will be directly placed in the medium-sized material basket. If leveling is required, it will be placed on the sorting conveyor belt. Medium-sized materials require at least one grabbing mechanism to grab, and can also be grabbed by two or more grabbing mechanisms at the same time.

[0091] The mobile cutting platform continues along the sorting and conveying channel through the large material sorting device. If there is large material, it will move the grabbing mechanism to the top of the large material through the large material sorting track and move the large material track, drop and grab the large material. If leveling is not required, it will be directly placed in the large material basket. If leveling is required, it will be placed on the sorting conveyor belt. Large materials require at least two grabbing mechanisms to grab at the same time, or they can be grabbed by three grabbing mechanisms at the same time.

[0092] At this time, only waste boards are left on the mobile cutting platform. The waste boards are moved from the mobile cutting platform to the waste placement table through the waste processing device. After completing this cutting task, the mobile cutting platform returns to the preparatory loading device and waits.

[0093] The medium-sized and large-sized materials on the sorting conveyor belt pass through the leveler and are placed in the corresponding medium-sized material basket or large-sized material basket through the leveling material stacking component.

[0094] The laser cutting automated production method of the present invention can realize the automated control of the entire process from laser cutting production planning to final completion. The production line is 300 meters long and can reach an annual production capacity of 200,000 to 300,000 tons.

It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art may make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. The embodiments of this application and the features in the embodiments may be combined with each other in any manner unless there is a conflict.
