[0025] When the above-mentioned composite circular knife die-cutting device is used, it can not only realize the automatic sorting of good and defective products, thereby improving production efficiency while avoiding damage to the products caused by manual operations, but also increase the friction between the product and the splicing belt to ensure the efficiency of the splicing belt in transporting the product, and can also pre-press the defective products to prevent them from flowing to the sorting belt of good products.

[0026] Working principle:

[0027] When in use, the first unwinding roller is used to unwind the base substrate, the multiple second unwinding rollers are used to unwind other strips that need to be laminated to the base substrate, and the multiple take-up rollers are used to take up the base substrate, the release film on the strip, and the waste material cut by the die-cutting unit;

[0028] The first die-cutting roller and the second die-cutting roller of the die-cutting unit can be rollers with smooth surfaces for laminating the material strip onto the base substrate by extrusion, or rollers with die-cutting blades for rolling-cutting the material strip and the base substrate as required after passing through the die-cutting gap formed therebetween;

[0029] According to the specific requirements of the product, the material belt and die-cutting unit are specifically set up, which belongs to the scope of existing technology and will not be described here;

[0030] The products die-cut by the die-cutting unit are moved onto the splicing belt in sequence;

[0031] When the products on the splicing belt are good, the piston rod of the sorting cylinder is extended. At this time, the splicing belt is connected to the first sorting belt. The good products are transferred to the first sorting belt through the splicing belt and finally fall into the splicing box downstream of the first sorting belt. During the above process, the second cylinder can be switched from the contracted state to the extended state. The friction between the good products and the splicing belt is increased by the pinch roller that moves with it to ensure the effectiveness and efficiency of the splicing belt transportation and prevent the good products from slipping on the splicing belt.

[0032] When the product on the splicing belt is defective, the piston rod of the sorting cylinder is placed in a retracted state. At this time, the splicing belt is connected to the second sorting belt. The defective products are transferred to the second sorting belt through the splicing belt and finally fall into the splicing box downstream of the second sorting belt. In the above process, the first cylinder can be switched from a retracted state to an extended state. The friction between the defective products and the splicing belt is increased by the pinch roller that moves with it to ensure the effectiveness and efficiency of the splicing belt transportation, prevent the defective products from slipping on the splicing belt, and improve the stability of the defective products on the splicing belt during the downward movement of one end of the splicing belt.

[0033] Sorting automation: The purpose is to solve the abnormal processing and differentiation problems that occur during manual scanning and inspection. It is suitable for scanning and automatic material collection auxiliary equipment in most industries. It solves the problem of excessive contact between products during manual scanning and reduces product deformation and scratches caused by insufficient manual scanning techniques. Through modules and fixed scanning guns, scanning, loading, differentiation and inspection are realized, which greatly improves the yield rate and CT. Combined with the scanning gun to scan the product QR code to check the MES system, MES sends instructions to the sorting automation, and the sorting automation distinguishes materials (OK / NG).

[0034] Action description: 1. The product flows to the lifting mechanism carrier plate and is positioned; 2. The barcode scanner is used to scan the code; 3. If the code is scanned, the lifting mechanism descends and flows to the NG material box; 4. If the code is scanned, the product flows to the OK material box; 5. When the material box is full, the material box module is moved to replace the material box.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
