Description

Technical Field

[0001] The present invention relates to the technical field of foam processing, in particular to a foam cutting and transfer equipment and a foam cutting and pasting method. Background Art

[0002] With the rapid development of information technology, various 3C (Computer, Communication, Consumer Electronics) products have become increasingly popular and deeply integrated into people's lives and work. As a key performance indicator for measuring the normal operation of electronic and electrical equipment in the electromagnetic environment and not causing unacceptable electromagnetic interference to other equipment, the importance of electromagnetic compatibility (EMC) has become increasingly prominent. The EMC performance not only directly relates to the stability and reliability of the product itself, but also involves the personal safety of users (such as medical equipment, automotive electronics) and the information property safety (such as data leakage, equipment malfunction), and has become one of the core requirements for global mandatory certification and market access. Among the many technical means to improve the EMC performance of products, using a functional overlay film (FOF) for local electromagnetic shielding and isolation is a widely used and effective solution.

[0003] The cutting process of the traditional wrapped FOF process mainly relies on manual or semi-automatic mechanical operations. The operator measures, positions, and cuts the rolled FOF material. This process is not only cumbersome, time-consuming, and laborious, but also highly dependent on the proficiency of the operator. It is difficult to ensure a high degree of consistency in cutting accuracy, and problems such as size deviation or edge burrs are likely to occur. In addition, since the wrapped application often requires multiple small pieces of FOF, the cutting operation becomes more scattered and repetitive, resulting in extremely low overall production efficiency, which has become a key factor restricting the product manufacturing cycle and cost control. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a foam cutting and transfer equipment to solve the above problems.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a foam cutting and transfer equipment, which is sequentially provided with a semi-finished product unwinding reel, a semi-finished product traction rubber roller, a cutting part, a vacuum adsorption part, and a finished product packaging part according to the production direction; The cutting part includes a first X-axis guide rail, a first Z-axis guide rail is arranged on the first X-axis guide rail, an actuator is connected to the first Z-axis guide rail, and a cutting circular knife is connected to the actuator; The vacuum adsorption part includes a second X-axis guide rail, a Y-axis guide rail is connected to one end of the second X-axis guide rail, a second Z-axis guide rail is arranged on the second X-axis guide rail, and a plurality of vacuum adsorption nozzles are connected to the second Z-axis guide rail; The finished product packaging part includes a finished product unwinding reel, the finished product unwinding reel is connected to a finished product winding reel through a bottom film of the finished product tape, and a bottom film traction rubber roller is arranged on the bottom film of the finished product tape.

[0006] As a further solution of the present invention, the cutting and pasting device further includes a platform, and a positioning fixture is provided on the platform.

[0007] As a further solution of the present invention, the positioning fixture includes a plurality of positioning plates, and the plurality of positioning plates are arranged at equal intervals.

[0008] As a further solution of the present invention, adjustment slots are opened at both ends of the platform, and locking blocks are connected to the outer sides of the first and last positioning plates.

[0009] As a further solution of the present invention, a semi-finished product take-up reel is provided on the lower side of the platform, and the semi-finished product take-up reel is connected to a semi-finished product pay-off reel through a bottom film.

[0010] As a further solution of the present invention, a plurality of vacuum suction nozzles are arranged at equal intervals.

[0011] As a further solution of the present invention, the distance between adjacent vacuum suction nozzles is adapted to the distance between adjacent positioning plates.

[0012] As a further solution of the present invention, the actuator is connected to a drive mechanism.

[0013] A method for cutting and pasting foam for a foam cutting and pasting device is as follows: Step 1: The products on the semi-finished product pay-off reel pass through the semi-finished product traction rubber roller and the positioning fixture in sequence. The bottom film under the products is wound by the semi-finished product take-up reel to drive the products to move forward. Step 2: When the product moves below the cutting part, the first Z-axis guide rail drives the actuator and the cutting circular knife to descend, and the first X-axis guide rail drives the first Z-axis guide rail and the cutting circular knife to cut the product. Step 3: The Y-axis guide rail drives the second X-axis guide rail, the second Z-axis guide rail and the vacuum suction nozzles to move above the cut product. The second X-axis guide rail drives the second Z-axis guide rail and the vacuum suction nozzles to move directly above the cut product. The second Z-axis guide rail drives the vacuum suction nozzles to descend to adsorb the product. Step 4: After the Y-axis guide rail drives the second X-axis guide rail, the second Z-axis guide rail and the vacuum suction nozzles to move onto the bottom film of the finished product tape, the vacuum suction nozzles place the product on the bottom film of the finished product tape, and the finished product take-up reel completes the winding process.

[0014] Since the present invention adopts the above technical solutions, the advantages and positive effects of the invention are: 1. The actuator can control the speed, forward and reverse rotation, and cutting depth of the cutting circular knife, which can significantly improve the processing quality and efficiency when cutting foam: speed adjustment is the key to different hardness (from soft low density to tough high density) and material characteristics such as fusible, high resilience or with sticky coating). High speed is suitable for soft foam to improve efficiency and reduce friction and heat adhesion, while low speed is used for hard foam to ensure stable penetration of the blade and avoid material tearing, so as to obtain a smooth and flat incision; the forward and reverse function directly optimizes the incision quality. Its short reversal can effectively shake off the debris adhering to the blade and remove the residue in the incision, prevent the pulling deformation caused by blockage, and ensure that the edge is always smooth and burr-free, especially for sticky or fusible materials; precise cutting depth control ensures complete cutting through the target layer (whether single layer or composite material), while avoiding damage to the bottom layer or table top, and adapting to the thickness fluctuation of the foam; 2. With the precise linkage of other motion axes (such as X, Y, and Z axes), the motion parameters can be dynamically adjusted (such as automatic speed reduction at corners), achieving high-precision cutting of complex 2D / 3D contours with excellent dimensional consistency; 3. This multi-dimensional adjustment greatly improves production efficiency. It matches the optimal speed, automatically clears chips to reduce downtime, guarantees one-time molding, and closely arranges to reduce waste. It also extends tool life, enhances equipment adaptability and production safety, and provides a core guarantee for high-quality, multi-variety foam cutting. 4. Through the synergistic effect of the semi-finished product unwinding reel, the semi-finished product traction rubber roller, the cutting part, the vacuum adsorption part and the finished product packaging part, the semi-finished product foam can be cut and transferred, which is highly automated, convenient and efficient to use, and has good practicality.
