Description

Technical Field

[0001] The invention relates to the field of die-cutting processing, and in particular to a knife-free die-cutting device for hole rotation positioning and a process thereof. Background Art

[0002] When processing the rubber or cotton materials used in mobile phones, a die-cutting machine is usually used to cut the material strips, and the material strips are cut into material units according to the shapes required by the mobile phone manufacturer; after the material units are packaged in batches, they are sent to assembly manufacturers downstream of the industrial chain to complete the pasting processing of the material units.

[0003] When processing the material tape, it will be decided whether to cut and shape it in one go or in steps, whether to use a flat knife (CCD die-cutting machine) or a circular knife (circular knife die-cutting machine), or a combination of the two, according to the shape to be processed. All of them must be set up according to specific molding requirements. When cutting, the release film and the material tape are usually cut simultaneously. The release film is attached to the adhesive surface of the material tape, which stabilizes the material tape during the die-cutting process. At the same time, after die-cutting, the release film will cover the material monomer to form a protective film, which is convenient for downstream companies to tear off the film and paste operations.

[0004] However, when cutting the material strip with high-viscosity adhesive backing without substrate, the size of the material monomer is inconsistent with that of the protective film. There is an area on the protective film that is not covered by the material monomer. After the die-cutting machine cuts a knife mark on the release film at this location, the adhesive backing of the non-hollow inner frame structure penetrates into the knife mark, resulting in poor peeling of the product cover film and the adhesive backing. Summary of the invention

[0005] In order to reduce the situation where the adhesive backing is not properly peeled off after a knife mark is cut on the release film, the present application provides a rotary hole positioning and knife-free die-cutting device and a process thereof.

[0006] In a first aspect, the present application provides a knife-free die-cutting device for rotary hole positioning.

[0007] The present application provides a rotary hole positioning non-knife stamping die-cutting device; the following technical solutions are adopted:

[0008] A rotary hole positioning non-knife stamping die-cutting device comprises a first die-cutting unit, a second die-cutting unit and a material receiving unit which are sequentially arranged along the material belt conveying direction; the first die-cutting unit is sequentially arranged at the input end from top to bottom with a first release film roller for unwinding a first release film, a material belt roller for unwinding a material belt and a bottom film roller for unwinding a bottom film, and the output end of the first die-cutting unit is provided with a first die-cutting roller, the first die-cutting roller is used to pass through the first release film and cut a boundary section between a non-adhesive area and a back adhesive area at a predetermined position of the protective film on the material belt, and the first release film retains the knife hole cut by the first die-cutting roller;

[0009] The second die-cutting unit is provided with a first winding roller for winding up the first release film and a second release film roller for unwinding the second release film in sequence along the material tape conveying direction. The second die-cutting unit is provided with a second die-cutting roller at the output end. The second die-cutting roller is used to cut the second release film along the circumferential direction to form the protective film without knife marks. The second die-cutting roller passes through the second release film and cuts the circumferential side of the material tape except the dividing section to form a material monomer.

[0010] The material receiving unit is used for receiving the material monomer and the protective film outputted by the second die-cutting unit.

[0011] By adopting the above technical scheme, in the first die-cutting unit, the first die-cutting roller cuts the first release film and the material tape synchronously, thereby cutting out the side of the material monomer on the boundary line between the non-adhesive area and the adhesive back area on the protective film, peeling off the first release film, and then attaching the second release film to the material tape and using the second die-cutting roller to shear the second release film. Because the shape of the adhesive back area of ​​the protective film is consistent with the shape of the material monomer, at this time, it is only necessary to cut out the shape of the protective film on the second release film, and the material monomer can be synchronously cut to form a complete material monomer; this method separates the first release film with internal knife marks from the material tape by replacing the release film, and re-laminates the material tape, and only performs circumferential cutting to obtain a protective film without knife marks.

[0012] Preferably, the first die-cutting roller is provided with a first cutter for cutting through holes in the material tape on the first die-cutting unit, and the first cutter cuts the material tape and the first release film synchronously.

[0013] By adopting the above technical solution, the through holes predetermined inside the material monomer are cut synchronously on the first die-cutting roller, so that the knife marks left during cutting are only left on the first release film, reducing the situation of knife marks left on the protective film.

[0014] Preferably, a waste discharge roller is provided on the first die-cutting unit, a waste discharge tape is wound around the waste discharge roller, and the width of the waste discharge tape is smaller than the width of the through hole.

[0015] By adopting the above technical solution, because the cross-sectional area of ​​the through hole is small, after the waste discharge tape is pasted on the material strip of the through hole part, the material strip with a larger area is stably transmitted under the clamping of each die-cutting unit, and the waste is discharged at the same time, reducing the workload of manual collection after the waste is scattered.

[0016] Preferably, the output end of the first release film on the first winding roller is used to connect with the input end of the first release film on the first release film roller, and the die-cutting device is also provided with a connecting component for connecting two first release films.

[0017] By adopting the above technical scheme, since only a small area of ​​knife holes remain on the first release film after being cut by the first die-cutting roller, and the first die-cutting roller only cuts the through-hole position and the boundary section, and will not damage the overall structure of the first release film, the first release film can still be transmitted; the first release film on the first winding roller is reconnected to the first release film on the first release film roller, the circulation of the first release film is started, and the first release film is reused to a certain extent. The first die-cutting roller can cut the material tape through the reused first release film, thereby reducing the first release film that originally needs to be discarded, thereby reducing the cost of replacing the release film.

[0018] Preferably, the docking assembly includes a docking frame and an adhesive component, the docking frame is installed on the first die-cutting unit, the first release film on the first winding roller is installed at the input end of the docking frame, and the first release film on the first release film roller is installed at the output end of the docking frame, and an adhesive block is installed on the docking frame in a lifting manner, and the adhesive block is used to extrude glue, and the adhesive block is squeezed on the end of the first release film on the first winding roller after descending; the docking assembly also includes a stabilizing component for securing each of the first release films on the docking frame.

[0019] By adopting the above technical solution, one of the first release films is first stretched and placed on the docking rack, the stabilizing component is started to stabilize the first release film, and then the first release film is glued using the adhesive block, and then the other first release film is overlapped on the bottom first release film to complete the docking, and finally the connected first release film is pulled horizontally out of the docking rack.

[0020] Preferably, the stabilizing component includes an air hole and a vacuum generator, the docking frame is hollow, the air hole is arranged on a side of the docking frame for placing the first release film, and the vacuum generator is installed in the docking frame and is used to create a vacuum in the docking frame.

[0021] By adopting the above technical solution, the vacuum generator draws a vacuum inside the docking rack, and when the first release film is placed on the air hole side of the docking rack, the first release film can be adsorbed on the docking rack through the air hole. When removing the first release film, the first release film can be directly pulled out from the docking rack, thereby realizing the rapid disassembly and assembly of the first release film on the docking rack.

[0022] Preferably, the docking frame is slidably installed on the first die-cutting unit along the material belt transmission direction, and a driving component for driving the docking frame to move on the first die-cutting unit is installed on the first die-cutting unit.

[0023] By adopting the above technical solution, after one of the first release films is placed and secured on the docking rack, the docking rack is moved closer to the other first release film through the movable docking rack, thereby shortening the distance between the two first release films and facilitating the operation of workers.

[0025] By adopting the above technical solution, when using the first release film, after the first release film, the material tape and the base film are inserted through the respective positioning holes at the same time, the three can be synchronized, so that the first die-cutting roller can accurately cut the first release film and the material tape; and after replacing with the second release film, the second release film can be positioned on the material tape by passing the positioning pins through the second release film, the material tape and the base film, so that the second die-cutting roller can accurately cut.

[0026] In the second aspect, the present application provides a non-knife stamping die-cutting process for hole rotation positioning, which adopts the following technical solution:
