Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, specifically referring to an online defect detection and adaptive trimming device for HIPS sheet metal. Background Technology

[0002] HIPS (High Impact Polystyrene) is characterized by its high stiffness, colorability, impact resistance, tensile strength, hardness, and lightfastness. It is primarily used as packaging material and also for the casings of household appliances. However, during extrusion molding, cooling, and subsequent processing, HIPS sheets are prone to surface defects, geometric deformations, and edge burrs due to process fluctuations, mold wear, or raw material impurities. Existing sheet trimming processes typically employ fixed-parameter mechanical or laser cutting equipment, where the cutting path must be pre-set and cannot be dynamically adjusted based on real-time detection results. This leads to inaccurate removal of defective areas, affecting the finished product yield; furthermore, fixed cutting widths result in material waste, especially when localized defects exist at the sheet edges, making it difficult to balance quality and cost requirements using traditional methods. Therefore, a novel online defect detection and adaptive trimming device for HIPS sheets is urgently needed to address these challenges. Utility Model Content
