Printing Industry
This sensor is a core inspection device for the paper feed system of a printing press. In applications such as book and magazine printing, packaging printing, and commercial printing, it is crucial to ensure that only a single sheet of paper enters the printing unit at a time. Double or overlapping sheets can cause paper jams, misaligned printed images, and ink waste.
The sensor monitors the paper feed status in real time and immediately triggers a shutdown or adjustment signal upon detecting multiple sheets, ensuring print quality and production efficiency. It is suitable for a variety of printing materials, including coated paper, newsprint, and cardboard.
Packaging Industry
In the packaging process for food, pharmaceuticals, and daily necessities, it is used to inspect the feed status of packaging materials (such as wrapping paper, aluminum foil, and laminated film). For example:
During the forming process of instant noodles and snack bags, it ensures accurate feeding of a single sheet of packaging film to prevent poor sealing or incorrect packaging caused by overlapping multiple sheets.
In the production of aluminum-plastic packaging for pharmaceuticals, it detects the feeding of single sheets of aluminum foil or laminated film to prevent
packaging defects.
It can also be used to inspect the cardboard feed in carton packaging to ensure the correct number of cardboard layers during carton forming. Paper Processing Industry
This covers processes such as paper slitting, folding, and binding. In processes such as notebook binding, folder making, and box forming, sensors can detect double or multiple sheets during stacking and conveying, preventing errors in subsequent processing steps (such as cutting and binding).
For example, on envelope production lines, sensors ensure that each sheet is accurately folded to prevent envelope seal failures caused by multiple pages.
Lithium Battery and Photovoltaic Industry
Lithium battery production: Detects the conveying status of thin materials such as electrodes and separators. Electrode sheets and separators are extremely thin (typically micron-level) and require high cleanliness. Non-contact ultrasonic sensors avoid material damage and accurately identify single/double sheets, preventing internal short circuits in the battery.
Photovoltaic Industry: During processes such as wafer sorting and cell lamination, sensors detect double or multiple wafers during conveying (thin and fragile) to ensure production quality of photovoltaic modules.
Semiconductor and Electronics Manufacturing: This sensor is used to inspect the conveying of materials such as PCBs, wafer sheets, and electronic tags. For example, during the pre-PCB placement process, sensors ensure that individual PCBs are accurately fed into the equipment, preventing soldering errors or equipment damage caused by overlapping multiple boards.
This is also applicable to the inspection of flexible electronic materials (such as flexible circuit boards), as their non-contact nature prevents damage to fragile electronic components.
Metal Processing and Metallurgy Industry
Inspect the feeding of individual sheets of metal foil (such as aluminum and copper foil) and metal sheets. In applications such as metal can molding and battery tab processing, sensors prevent multiple sheets of metal material from simultaneously entering the stamping equipment, preventing mold damage and product scrap.
For example, on aluminum foil lunch box production lines, sensors ensure the accurate feeding of individual sheets of aluminum foil, ensuring stamping accuracy.
Other Industries
Automotive Manufacturing: Detects the number of material layers during the cutting and lamination processes of automotive interior parts (such as leather and fabric sheets).
Textile Industry: Detects individual sheets of material during fabric slicing and non-woven fabric processing.
Pharmaceutical Industry: Detects the feeding status of paper or aluminum-plastic panels during processes such as medicine box packaging and instruction sheet folding, meeting the high-precision requirements of pharmaceutical production.
