[0002] A multi-station rotary die-cutter, also known as a rotary press, is commonly known as a circular knife machine, hob cutter, or multi-station circular knife die-cutting device. It uses a continuous rotary die-cutting process in the form of a hob and is one of the most efficient die-cutting machines. Currently, some electronic product components are produced using circular die-cutting. These components consist of release film, molding compound, and film handles. Current processing methods primarily involve cutting the raw material onto the release material to form the molding compound, which is then cut into the finished product.

[0029] The first sorting belt 16 and the second sorting belt 17 are each provided with a receiving box 12 at one end away from the receiving belt 15;

[0030] The first die-cutting roller 52 and the second die-cutting roller 53 of the above-mentioned die-cutting unit 5 are connected through mutually meshing gears 10. The end of the first die-cutting roller 52 or the second die-cutting roller 53 opposite to the gear 10 is connected to a drive component installed on the die-cutting base 51.

[0031] When the above-mentioned multi-station circular knife die-cutting device is used, it can detect the length and width of the die-cut product while triggering four flying cameras with zero delay to synchronously take pictures of the moving die-cut product, avoiding photo distortion and reduced detection accuracy due to signal delay, and realizing accurate measurement of the size of the die-cut product. It can also realize one-to-one binding between measurement data and each product through a barcode scanner and the product code on the base material, and can automatically sort good and defective products according to the measurement results, thereby improving production efficiency while avoiding damage to the product caused by manual operation.

[0032] Working principle:

[0033] 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;

[0034] 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;

[0035] 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;

[0036] After laminating and cutting multiple layers of material strips, and before the product is formed but cut, four flying cameras are used to photograph and measure the four corners of the product to obtain the product's length and width. The measurement data is then bound to each product through the product code. During this process, the four flying cameras are connected to the signal trigger via the same IO signal transmission line. This allows the four flying cameras to be triggered synchronously with zero delay to take photos of the moving die-cut product, avoiding photo distortion and reduced detection accuracy caused by signal delay, thereby achieving accurate measurement of the die-cut product dimensions.

[0037] Afterwards, the products passing through the die-cutting unit near the splicing component are cut, and the barcode scanner downstream of the flying camera determines the products passing under it to facilitate subsequent product sorting;

[0038] The cut products are moved to the splicing belt of the splicing component in sequence;

[0039] 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 from the splicing belt to the first sorting belt and finally fall into the splicing box downstream of the first sorting belt.

[0040] 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.

[0041] Flying CCD: By designing and customizing a special fixing mechanism for the multi-station circular knife die-cutting device, four CCDs are fixed on the multi-station circular knife die-cutting device, and then connected to the die-cutting machine signal trigger through a modified 4-in-1 IO signal line, so that the four CCDs can be triggered to take photos and measure at the same time, achieving zero-delay signal triggering, realizing product size, precise measurement, and 100% inspection.

[0042] 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).

[0043] 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.

[0044] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. 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. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
