Die‑cut parts are widely applied in the 3C electronics, new energy and packaging printing industries. There is a great variety of products including foam, double‑sided tape, Mylar sheets, insulating gaskets and protective films. These workpieces are thin and light with complex irregular profiles, featuring numerous inspection characteristics such as outer frames, special‑shaped slots, round holes and positioning holes. Traditional quality inspection methods can hardly balance inspection efficiency and measurement accuracy.
Adopting large‑lens stitching imaging technology, low‑glare anti‑reflective light source and intelligent edge‑recognition algorithm, the WV Flash‑Measurement Series of Chongqing Wanwei Automatic Stitching Flash‑Measuring Instrument can complete batch inspection of various die‑cut workpieces with one single device. It automatically finishes dimension judgment, defect marking and inspection report export, providing a one‑stop high‑efficiency visual inspection solution for quality control of die‑cutting processing enterprises.
Due to the features of thinness, softness, irregular shapes and multiple holes, die‑cut products bring long‑standing difficulties to enterprise quality‑inspection procedures:
Wide product range and tedious model‑change debugging: Traditional inspection equipment requires frequent fixture replacement and inspection program commissioning, and fails to satisfy the demand for rapid‑rotation inspection of multi‑variety products.
Difficulty in profile recognition for transparent and high‑reflective materials: Workpieces such as PET films and transparent double‑sided tape are prone to generate reflective halos on surfaces, blurring product contours and resulting in large measurement and recognition errors.
Low efficiency and high measurement errors of manual inspection: Manual multi‑dimensional dimension measurement and manual data recording have high error rates. Defective products are detected belatedly, bringing high rework costs.
No intuitive traceability for defect positions: Traditional inspection only outputs dimension values, and cannot visually mark out‑of‑tolerance positions, which is unfavorable for mold adjustment and production‑line optimization.

For mixed‑inspection scenarios of multi‑variety die‑cut parts, the WV‑series Automatic Stitching Flash‑Measuring Instrument of Chongqing Wanwei adopts the large‑lens stitching flash‑measurement solution. Workpieces can be placed arbitrarily without complicated positioning fixtures, and it is applicable to various die‑cut workpieces such as foam, double‑sided tape, Mylar insulating sheets, PET protective films and rubber gaskets.
The Wanwei WV Flash‑Measurement Series Automatic Stitching Flash‑Measuring Instrument supports full‑area automatic measurement via large‑field‑of‑view stitching. It captures all geometric dimension elements including length, width, hole spacing and special‑shaped profiles with one‑click operation. The system automatically distinguishes qualified and defective products with red‑green colors and pops up OK/NG judgment results to avoid manual checking procedures. Equipped with low‑glare anti‑reflective light source, the device overcomes edge‑finding difficulties of transparent and high‑reflective materials.
Inspection data is automatically stored, and inspection reports can be exported with one click, eliminating errors caused by manual recording and realizing full‑process quality traceability of products. Compatible with inspection of complex features such as round holes, chamfers and special‑shaped profiles, reusable inspection programs greatly shorten commissioning time for product model changes and improve batch quality‑inspection efficiency.
