[0002] Die cutting is a process that uses a die to cut a material into a desired shape. Typically made of metal, these dies can cut surfaces such as paper, fabric, adhesives, and leather into the desired shape. Rotary die cutting is a special type of die cutting that uses a cylindrical die that moves back and forth in a circular motion, with a blade that cuts the desired shape around the entire cylinder.
[0003] Currently, some electronic product components are produced using a circular die-cutting process. The resulting parts consist of release film, molding compound, and film handles. The current processing method primarily involves cutting the raw material onto the release material to form the molding compound, and then cutting the release material into the finished product. The existing circular die-cutting process for processing electronic product components presents the following issues: Product identity cannot be effectively traced; multiple CCD cameras on die-cutting equipment for electronic product parts cannot be triggered simultaneously to capture images, resulting in significant latency. The quality (size) of the processed products cannot be 100% confirmed, and traceability is difficult.

[0034] When the die-cutting processing equipment for electronic product parts is used, the back side of the reversed base substrate is stenciled, thereby achieving continuous and efficient stenciling operation without being affected by the drying time of the stencil ink and ensuring the integrity of the stencil pattern and the traceability of the stencil-based product;
[0035] In addition, while detecting the length and width of the die-cut products, four flying cameras can be triggered with zero delay to synchronously take pictures of the moving die-cut products, avoiding photo distortion and reduced detection accuracy due to signal delay, and achieving accurate measurement of the die-cut product dimensions.
[0036] Working principle:
[0037] 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;
[0038] 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;
[0039] 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;
[0040] The base material in roll form is usually transparent PET;
[0041] The base substrate is mounted on a first unwinding roller, and one end of the base substrate is pulled out and passed through a reversing shaft and a reversing assembly in sequence, and then passes through a plurality of die-cutting units in sequence downstream;
[0042] In the above process, the back of the substrate moves through the reversing shaft to the reversing assembly, facing the inkjet printer. The inkjet printer prints the product code on the back of the substrate at regular intervals. After that, the substrate moves through the reversing assembly to the die-cutting unit, and the substrate is restored to the state where the front side faces upward and continues to move to the downstream die-cutting unit for subsequent processes.
[0043] Based on the above arrangement, the bottom substrate originally facing up is reversed twice and the product code is sprayed on the back of the bottom substrate during the process, thereby eliminating the influence of the drying time of the coding ink.
[0044] After the multi-layer material strips are compounded and cut, and the product is formed, four flying cameras are used to photograph and measure the four corners of the product to obtain the length and width of the product, and the measurement data is bound to each product through the product code. During this process, the four flying cameras are connected to the signal trigger through the same IO signal transmission line, which can trigger the four flying cameras to take pictures of the moving die-cut products synchronously with zero delay, avoiding photo distortion and reduced detection accuracy due to signal delay, and realizing accurate measurement of the size of the die-cut products.
[0045] Non-contact inkjet coding: The inkjet coding equipment is fixed to the die-cutting processing equipment of electronic product parts through a customized fixing mechanism, connected to the customized MES system, and the coding content is issued, so that it can be used to code the products on the die-cutting processing equipment of electronic product parts. The product code is then checked by the rear scanner. This can prevent problems such as product traceability caused by wrong codes, duplicate codes, and missed codes.
[0046] Flying CCD: By designing and customizing a special fixing mechanism for die-cutting processing equipment for electronic product parts, four CCDs are fixed on the die-cutting processing equipment for electronic product parts, 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.

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.
