Background Technology

[0002] In the production of rolled materials, the detection and removal of surface defects (such as bubbles, foreign objects, and damage) is a crucial step in ensuring product quality. Traditional methods mainly rely on manual visual inspection or semi-automatic equipment for removal, which suffers from low efficiency, high missed detection rate, and insufficient positioning accuracy. In addition, existing equipment lacks precise positioning indicators during the removal action, which can easily lead to misoperation or the retention of defective products.

[0003] To address the aforementioned problems, this invention proposes a fully automatic roll material removal mechanism. By integrating high-precision motion control, adhesive removal technology, and laser positioning indication, it achieves rapid identification, accurate positioning, and efficient removal of defective products, significantly improving production efficiency and product quality. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a roll material removal mechanism, comprising the following core components: (1) Planar moving device: The movement of the plane X-axis and Y-axis is controlled by two servo motors respectively to achieve precise positioning of the roll material with a positioning accuracy of ±0.01mm; (2) Lifting device: The vertical movement is controlled by a double-acting cylinder with a stroke range of 50mm to 200mm, and a magnetic sensor is configured to detect the piston position in real time to ensure the stability of the removal action; (3) Unloading and winding device: includes two guide wheels and a stepper motor. The surface of the guide wheels is covered with replaceable adhesive material (adhesive force 5N / cm² to 20N / cm²). The guide wheels are driven to rotate by a synchronous belt. The surface of the guide wheels is provided with anti-slip texture (friction coefficient ≥0.4). Defective products are adsorbed and removed by adhesive method. (4) Laser pointing device: Equipped with a slanted laser pointing device with an emission angle of 30° to 60°, a wavelength of 630nm to 670nm, and a spot diameter of ≤1mm, used to provide high-precision positioning and pointing of the target area before removal; (5) Control system: integrates PLC module and HMI touch screen, coordinates the running sequence of servo motor, cylinder, stepper motor and laser indicator, and supports manual debugging and automatic operation mode switching; (6) Compared with the prior art, the beneficial effects of the present invention include: (7) High-precision positioning: The XY axis servo motor closed-loop feedback system works in conjunction with the laser indicator, and the positioning error is ≤ ±0.01mm; (8) High-efficiency removal: The adhesive guide wheel is combined with the stepper motor for synchronous drive, and the time for a single removal action is ≤0.5 seconds; (9) Intelligent control: The equipment status is monitored in real time through the touch screen, and an emergency stop button is provided to ensure the safety of operators and equipment; Attached Figure Description

[0006] As shown in the attached figure, the roll material removal mechanism includes an aluminum alloy frame (1), with a planar moving device (2) installed on the top of the frame (1). The slide table is driven by an X-axis servo motor (201) and a Y-axis servo motor (202) to achieve planar positioning. A lifting device (3) is connected above the slide table, and a double-acting cylinder (301) drives the removal head (302) to move vertically. A feeding and winding device (4) is provided in the middle of the frame (1). A stepper motor (401) drives a guide wheel (402) to rotate through a coupling. The surface of the guide wheel is covered with an adhesive layer (403). A laser indicator device (5) is installed on the side of the feeding and winding device (4). The oblique laser beam is activated before removal and projected onto the surface of the roll material to mark the location of defective products. The control system (7) integrates a PLC and a touch screen, and controls the coordinated operation of each device through a preset program: Positioning phase: The servo motor drives the slide to the target coordinates, and the laser pointer calibrates the removal point; Removal stage: The cylinder presses down to make the suction head contact the roll material, and the guide wheel rotates to adsorb the defective product into the adhesive layer; Waste disposal: The adsorbed waste is wound into the waste bin by the guide wheel.
