Description

Technical Field

[0001] The invention relates to the field of sheet material processing, in particular to an automatic sheet material production line and a production method. Background Art

[0002] At present, sheet metal processing such as cutting and bending processes are basically single-machine operations, all relying on manual loading and unloading, manual operation of laser cutting machines, and manual sorting after cutting. The cut sheets are then sent to the bending machine for bending. The flow between processing processes is heavily dependent on manual labor, resulting in unstable production capacity and increased labor operation costs. If different sheets need to be switched for processing, the sheets need to be replaced manually, which is not conducive to large-scale processing needs;

[0003] In addition, it was found that there was no relevant positioning and coding mechanism designed before the existing bending process, so the sheet metal would be offset, resulting in inaccuracy in the product after bending, and the consistency of product processing could not be guaranteed.

[0018] On the other hand, the present invention also provides a method for automatic sheet metal production, which is processed by the above-mentioned automatic sheet metal production line, and the method comprises the following steps:

[0019] S1. Preparation

[0020] The technicians generate the part processing program through the upper computer software and upload it to the part database. The automatic feeding mechanism, crawler cutting and coding mechanism, automatic material suction and coding mechanism, automatic lifting and feeding mechanism, and automatic bending mechanism automatically obtain their processing data from the part program. The part database contains the information data of different sheets and the setting of sheet material suction cup matching program. The program can correctly open the suction cups at the positions covered by the sheet material, and disable the suction cups at the positions not covered by the sheet material, and set the cutting and bending processes matching different sheets.

[0021] S2, loading, coding, cutting

[0022] The sheet material on the A storage rack or the B storage rack is sucked and transferred to the crawler conveyor mechanism of the crawler cutting and coding mechanism through the automatic feeding mechanism. According to the current sheet material processing requirements, the sheet material is coded by the laser coding machine of the crawler cutting and coding mechanism. After the QR code is coded, the sheet material is cut by the laser cutting machine according to the cutting process set by the system, and the cut sheet material is conveyed by the crawler conveyor mechanism.

[0023] S3, feeding, positioning, centering, and stacking

[0024] The information of the laser cutting machine's cutting completion is fed back to the control system, and the control system controls the automatic material suction and coding mechanism to move to the top of the crawler conveyor mechanism, and the automatic material suction and coding mechanism uses the code scanning and recognition camera to quickly take photos to recognize the QR code and read the database information set for the current sheet material, and then finds the program information consistent with the sheet material name after comparison and screening with the sheet material name in the database, and then loads it to the controller of the suction cup mechanism. The suction cup mechanism selects the corresponding suction cup matching program according to the sheet material name recognized by the photo, and transfers the cut sheet material to the workbench through the matching vacuum suction cup, and then uses the positioning and coding mechanism to position and center the cut sheet material and straighten the coding material;

[0025] S4, feeding, bending, unloading

[0026] After the alignment is completed, the suction cup mechanism is closed and the pressure plate mechanism is opened. The aligned sheet material is pressed on the reversing suction cup of the automatic lifting and feeding mechanism through the pressure plate of the pressure plate mechanism, and the reversing suction cup is opened at the same time, so that the sheet material is well adsorbed by the reversing suction cup, and then the sheet material is sent to the automatic bending mechanism by the feeding motor of the automatic lifting and feeding mechanism for bending according to the set bending process. After one side is bent, the feeding motor of the automatic lifting and feeding mechanism returns to the original path, and the reversing motor is turned on to rotate the reversing suction cup 180 degrees to complete the reversal of the sheet material, and then the sheet material is sent to the bending mechanism by the feeding motor to complete the bending of the other side. Finally, the bending of both sides of the sheet material is completed, and then the feeding motor returns to the original path to send the bent sheet material to the bottom of the suction cup mechanism, and finally it is sent to the unloading rack for discharge through the suction cup mechanism.

The cut sheet material is then coded and aligned through the automatic material suction and coding mechanism 3, and then sent to the automatic bending mechanism 5 through the automatic lifting and feeding mechanism 4 for bending the two sides of the cut sheet material. Finally, it is sent to the unloading rack 6 through the automatic material suction and coding mechanism 3 for unloading.

The sheet material 100 is transferred to the crawler-type cutting and coding mechanism 2 through the automatic feeding mechanism 1 for coding first and then cutting, and then the cut sheet material is centered and coded by the automatic material suction and coding mechanism 3. After that, the processing accuracy of the sheet material in the subsequent bending process is improved, and the sheet material is sent to the automatic bending mechanism 5 by the automatic lifting and feeding mechanism 4 to cut and bend the two sides of the sheet material, and finally sent to the unloading rack 6 for unloading through the automatic material suction and coding mechanism 3; in this embodiment, the automatic material suction and coding mechanism 3 includes a code scanning and recognition camera 37, which can identify the spray code before cutting, automatically adjust the working number of the vacuum suction cup 1 of the suction cup mechanism, and the bending mechanism bends according to the preset sheet material bending program, which is fully automated, improving the bending efficiency and the subsequent sorting efficiency of different sheets. Of course, the present invention is equipped with a matching sheet material information database. Before work, the technician will generate the configuration program of each mechanism through the sorting software, and push it to the suction cup database through the network after the processing is completed. The working number of the vacuum suction cup 1 of the suction cup mechanism is adjusted according to different sheets, which improves the accuracy and flexibility of the suction cup mechanism operation.

[0065] S2, loading, coding, cutting

[0066] The sheet material on the A storage rack 131 or the B storage rack 132 is sucked and transferred to the crawler conveyor mechanism 22 of the crawler cutting and coding mechanism 2 by the automatic feeding mechanism 1.
