Description

Technical Field

[0001] This invention relates to the field of automobile production equipment technology, specifically to a mobile material collection and stacking device and its control method. Background Technology

[0002] In the production of automotive parts, some parts need to be stamped into sheets by a stamping machine, and then sent to subsequent processes after being collected, stacked and processed.

[0003] For customers with high requirements for sheet metal surface quality and stacking accuracy, a side-feeding collection solution is as follows: Figure 1 As shown, after the sheet metal is guided out using a simple feeding device, it is stacked and aligned manually. This is labor-intensive, requiring at least two people to lift the sheet metal each time, resulting in high labor costs. If the sheet metal scrapes against the device or the stacking process during lifting, surface quality problems will also occur, leading to inconsistent quality. There are also some simple mechanical collection and stacking fixtures, such as... Figure 2 As shown, the gap between the perimeter side panels of the simple fixed stacking frame and the sheet material should be at least 10mm; otherwise, the sheet material will get stuck when falling into the stacking frame. This results in an edge misalignment of about 10mm, far exceeding the quality standard of <3mm required for high quality. Furthermore, due to the small amount of material in the initial stacking stage, the sheet material falls with a large drop, causing damage to the sheet material below when it is hoisted in, leading to quality problems.

[0004] Chinese utility model patent CN207272003U (authorization announcement date: April 27, 2018) discloses a material dropping and stacking mechanism for an automatic sheet material receiving and stacking device. This mechanism uses a four-bar linkage to flip the sheet material above the left and right receiving roller mechanisms downwards, causing it to fall and be stacked between several limiting rods on the stacking support plate. While this method eliminates the need for operator intervention, effectively reducing the number of workers, lowering production costs, reducing worker workload, improving efficiency, and enhancing safety, it suffers from several drawbacks. While the stacking is limited by the left and right limiting rods, there are no limiting rods on the front and back sides, resulting in low stacking accuracy. Furthermore, it cannot prevent quality issues such as insufficient material in the initial stacking stage, large drop differences in sheet material, and damage to lower sheets caused by the initial lifting of new material.
