The goal of all automated production lines is zero waste. In view of today's high-speed technology and potential human error, this goal is difficult to achieve. Typical defects that can be identified by visual inspection include label defects, sealing defects, sealing defects, product and packaging integrity defects, printing defects and container defects. A perfect visual inspection mechanism should include the following inspection items: the inspection items describe the appropriate filling amount of the whole bottle; The existence, height, color and skew of the cover; The existence, location and identification of tags. Check the existence, position, direction, counting and correctness of product covers in the box. Check the decoration, ID and sealing position outside the box; Print product code and date/batch number. Correct cover position detection Cover detection: presence, height, inclination, color, safety belt integrity. Product ID verification ensures that the ID code of any product exists, is readable and correct. Bottleneck measurement (edge to edge, height and thread width) detects the width (e edge to edge), height (h) and thread width (t) of glass bottle neck. Flatness detection checks whether there are hairs, threads or wavy surfaces on the top of the container due to uneven cutting during fine adjustment. Contaminant detection can detect any defects on the side wall of the container, including dust, scars, stains and built-in or surface particulate matter accumulated during injection molding. Roof breakage inspection confirms that there are no holes, fragments, lost glass and fragments at the top of the glass container. The presence of cork can also be determined. Other detection barcode/QR code verification, label control number (LCN) verification, inclined label detection,
Corner label detection, label existence inspection, etc.
