Description

Technical Field

[0001] This invention relates to the field of die-cutting production technology, and in particular to a die-cutting device and method for multi-layer laminated products. Background Technology

[0002] With the rapid development of the electronics industry, especially the expanding range of consumer electronics products, die-cutting is no longer limited to the post-printing stage; it has become an auxiliary material in the production of industrial electronic products. Common applications include: electroacoustics, healthcare, display signage, security, transportation, office supplies, electronics and power, communications, industrial manufacturing, and home entertainment. It is used in products such as mobile phones, MIDs, digital cameras, automobiles, LCDs, LEDs, FPCs, FFCs, and RFID, and is increasingly being used for bonding, dustproofing, shockproofing, insulation, shielding, and thermal protection in these products.

[0003] Existing technologies for multi-layer laminated products often require multiple processes to die-cut different materials before lamination. This is not only cumbersome but also generates waste material at each stage, which is abundant and scattered. For example, a dustproof and waterproof product, from bottom to top, consists of release film or release paper, double-sided tape, dustproof mesh, and adhesive film. The required molds are MA, MB, and MC. MA is used to punch the inner hole of the double-sided tape (the inner hole is unwanted waste material, usually directly punched in the blanking mold). (Waste discharge); MB is the die for the tear-off part, which removes the double-sided adhesive waste that is not needed in the tear-off part); MC is the die for the outer shape. The process flow is as follows: 1. The J-1 laminating machine laminates the double-sided adhesive (B) and release film (A), and removes the self-adhesive release paper (f-1) and replaces it with single-sided release paper (I-1); 2. The material is then fed into the J-2 die-cutting machine for die-cutting, and the part of the product's inner hole that does not need double-sided adhesive is removed by die-cutting; 3. After the first die-cutting, the original release paper is collected as waste (f-2), exposing the double-sided adhesive for dust prevention. 1. Apply the net (C) and then attach the blue protective film (D) as the tear-off area, and discard the release film attached to the blue protective film (D) (f-3); 2. Apply the middle adhesive film (I-2) as the base film; 3. After the above steps are completed, reverse the material and die-cut to the tear-off area of ​​the blue protective film (D); 4. Collect the waste material f-4 (replace the release film I-4); 5. Perform a third die-cut, removing the middle adhesive film (I-2) that was originally used as the base film; 6. Die-cut the outer shape (MC mold). Die-cut to halfway through the release film, collect waste (f-6); 9. Slice; 10. Inspect and package. The processing steps are cumbersome, the work efficiency is low, and the waste generated is as follows: f-1 double-sided adhesive with release paper, f-2 waste edge material generated after MA die-cutting, f-3 blue protective mold with release film, f-4 waste edge material generated after MB die-cutting, f-5 tearing off the middle adhesive film, f-6 waste edge material generated after MC die-cutting. The waste is large, which seriously wastes resources, is costly, and is not conducive to environmental protection.

[0004] Therefore, there is an urgent need for a multi-layer bonding die-cutting device that simplifies the process, increases work efficiency, and generates less waste. Summary of the Invention

[0027] The purpose of this invention is to provide a die-cutting device and method for multi-layer laminated products to solve the problems existing in the prior art. It uses the same die-cutting machine to die-cut and laminate multiple laminating materials, simplifies the operation steps, improves work efficiency, and eliminates the need for auxiliary materials used during die-cutting machine switching, thereby reducing the amount of auxiliary materials used, reducing costs, reducing waste generation, and improving environmental protection.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to the following: Figure 1-4 As shown, a multi-layer laminated product die-cutting device is provided, including a first conveying mechanism, at least one second conveying mechanism, and a die-cutting machine 11. The first conveying mechanism is used to convey the bottom layer laminating material, and the second conveying mechanism is used to convey the top layer laminating material. The number of second conveying mechanisms is the same as the number of layers of the top laminating material. The die-cutting machine 11 is provided with a plurality of dies for processing different laminating materials. The plurality of dies are arranged sequentially along the conveying direction of the first conveying mechanism. The laminating material conveying paths of the first conveying mechanism and the second conveying mechanism intersect in the die-cutting area of ​​the die-cutting machine 11. Preferably, the laminating material conveying paths of the first conveying mechanism and the second conveying mechanism are perpendicular to each other, and the laminating material conveying path of the second conveying mechanism corresponds to the die for processing it. In the conveying direction, the bonding material conveying paths of several second conveying mechanisms are arranged sequentially from bottom to top according to the number of bonding layers. This device integrates the die-cutting molds used to process multi-layer bonding materials onto the same die-cutting machine 11. As the bottom bonding material is conveyed, the upper bonding material is continuously conveyed to the top of the bottom bonding material in the die-cutting area. As the die-cutting machine 11 performs its die-cutting operation, the upper bonding material is simultaneously die-cut and bonded to the bottom bonding material. This achieves die-cutting and bonding of multi-layer bonding materials within the same die-cutting machine 11, simplifying the operation steps, improving work efficiency, and saving the auxiliary materials used when switching die-cutting machines 11, thus saving energy and reducing costs. In addition, as the amount of auxiliary materials used decreases, the amount of waste generated also decreases, which is beneficial to improving environmental protection.

[0030] Both the first conveying mechanism and the second conveying mechanism include a feeder, a take-up machine, and a traction roller 10. The feeder and the take-up machine are located on both sides of the die-cutting machine 11, and the traction roller 10 is set on the material conveying path.

[0031] Taking waterproof and dustproof multi-layer laminated products as an example: the bottom layer of the laminated material is double-sided adhesive 2 with a release film or release paper 1 on the bottom, and the top layer of the laminated material, from bottom to top, is a dustproof mesh 3 and an adhesive film 4.

[0032] The specific device for dustproof multi-layer laminated products is as follows: the feeder of the first conveying mechanism includes a double-sided adhesive conveying roller 5, a release film or release paper conveying roller 6, a pressing roller 7 for pressing the adhesive surface of the double-sided adhesive 2 and the release film or release paper 1, a first separating component 8 for peeling off the release paper attached to the double-sided adhesive 2, and a first take-up roller 9 for winding up the release paper attached to the double-sided adhesive 2. A pressing roller 7 is provided between the double-sided adhesive conveying roller 5 and the release film or release paper conveying roller 6 and the die-cutting machine 11. The structure of the pressing roller 7... The device consists of two rollers arranged vertically, which press the adhesive surface of the double-sided adhesive 2 and the release film or release paper 1 together using the gap between them. The first separating member 8 is located between the pressing roller 7 and the die-cutting machine 11. The first separating member 8 has a wedge-shaped structure with the pointed end corresponding to the material coming from. It uses its pointed end to separate the double-sided adhesive 2 from its own release paper. The first separating member 8 is located above the conveying path of the double-sided adhesive 2. The first receiving roller 9 is located above the first separating member 8. The traction roller 10 is located between the first separating member 8 and the die-cutting roller.

[0033] The die-cutting machine 11 can be used for wood board molds, plastic board molds, QDC molds, engraving molds, etching molds, blanking molds, etc.

[0034] The die-cutting machine 11 has the following specific structure: it includes a base plate 18 and a top plate 17. The top plate 17 is positioned above the base plate 18 and moves vertically. Along the conveying direction of the first conveying mechanism, the lower surface of the top plate 17 is sequentially equipped with a first die 12 for cutting the double-sided adhesive 2 to half its length, a second die 13 for cutting the double-sided adhesive 2 to half its length, a third die 14 for cutting to half its length and attaching the dustproof net 3 to the double-sided adhesive 2, and a fourth die 15 for cutting to half its length and attaching the adhesive film 4 to the dustproof net 3. The first die 12 is a hollow, elongated structure perpendicular to the conveying direction of the first conveying mechanism. The central hole of the first die 12 extends upward through the top plate 17, providing a discharge channel for the waste material 16. Along the length of the first die 12, the first die 12 faces the end of the conveying mechanism. The end face is uniformly provided with several arc-shaped grooves; the second die 13 includes several hollow cylindrical structures uniformly distributed along the length direction of the first die 12, the second die 13 is provided with the grooves of the first die 12, and the central through hole of the second die 13 penetrates the top plate 17 upward to provide a discharge channel for the waste material 16; the third die 14 is a long strip structure perpendicular to the conveying direction of the first conveying mechanism, the end of the third die 14 corresponding to the arc-shaped groove of the first die 12 is provided with an arc-shaped protrusion, and the bottom outer edge of the third die 14 extends downward to form a punching groove; the fourth die 15 is a number of cylindrical structures that match the shape of the preset adhesive film 4 and are uniformly distributed along the length direction of the first die 12, the bottom outer edge of the third die 14 extends downward to form a punching groove, and the cylindrical structure of the fourth die 15 is provided with the arc-shaped groove of the first die 12.

[0035] The movement of the top plate 17 can be controlled by a telescopic cylinder, and guide rods are vertically installed at the four corners of the bottom plate 18. Guide holes are provided on the top plate 17 at the positions corresponding to the guide rods. The guide rods are slidably installed in the guide holes to guide the movement of the top plate 17.

[0036] The die-cutting mold needs to be treated to prevent sticking.

[0037] The material receiving machine includes a waste tape conveyor roller 20, a second separating member 21 for peeling the waste tape 19 adhered to the product, a second receiving roller 22 for winding the waste tape 19, and a receiving paper tube 23 for winding the finished product. The waste tape 19 conveyed by the waste tape conveyor roller 20 is attached to the product with the adhesive side facing down through the pressing roller 7. The second separating member 21 is located on the side of the pressing roller 7 away from the die-cutting machine 11. The second receiving roller 22 is located above the second separating member 21. The second separating member 21 has the same structure and function as the first separating member 8. The receiving paper tube 23 is located on the side of the second separating member 21 away from the die-cutting machine 11. The waste tape 19 can be used to directly stick up and remove useless edge material without manual operation, thus improving the automation level of the device.

[0038] The conveying motors of the first and second conveying mechanisms are both electrically connected to the control system. The control system controls the conveying speed of the first and second conveying mechanisms, enabling them to cooperate within the die-cutting area.

[0039] The present invention also provides a die-cutting method for the above-mentioned multi-layer laminated product die-cutting device, comprising the following steps:

[0040] S1: The first conveying mechanism conveys the bottom bonding material to the die-cutting machine 11, and the corresponding die on the die-cutting machine 11 performs die-cutting on the bottom bonding material;

[0041] S2: The bottom bonding material continues to move inside the die-cutting machine 11 to below the cross-conveyed upper bonding material. While the die-cutting machine 11 is die-cutting the upper bonding material, the downward pressing action of the die-cutting machine 11 adheres the upper bonding material to the bottom bonding material.

[0042] S3: Continue conveying until several upper bonding materials are die-cut and bonded. After bonding, the paper rewinding tube 23 will rewind the paper and hand it over to the next workstation for quality inspection.

[0043] In the production of dustproof multi-layer laminated products, in step S1, the double-sided adhesive 2 and the release film or release paper 1 are pressed together by the pressing roller 7 and then conveyed to the first separating part 8. The release paper of the double-sided adhesive 2 is separated and wound onto the first receiving roller 9. The double-sided adhesive 2 with the release paper removed continues to move to the die-cutting area between the top plate 17 and the bottom plate 18 of the die-cutting machine 11. The first die 12 presses down and punches the double-sided adhesive 2 until the release film or release paper 1 is half-cut. After the punching is completed, the double-sided adhesive 2 continues to move to the bottom of the second die 13. The second die 13 presses down with the top plate 17 and punches the double-sided adhesive 2 until the release film or release paper 1 is half-cut. At this time, long strip holes and round holes are formed on the double-sided adhesive 2.

[0044] In steps S2 and S3, the double-sided adhesive 2 moves to below the third die 14, and the dustproof net 3 is also conveyed to below the third die 14. The third die 14 presses down with the top plate 17 to punch and cut the dustproof net 3, punching the double-sided adhesive 2 until the release film or release paper 1 is half-cut, punching it into a long strip shape and attaching it to the double-sided adhesive 2. The punched long strip dustproof net 3 is attached to the round hole, and its protruding position corresponds to the position of the groove punched by the first die 12 of the double-sided adhesive 2. After the third die 14 completes the punching, the double-sided adhesive 2 continues to move to the fourth die 15 and is lifted up. The adhesive film 4 is also conveyed to below the fourth die 15. The fourth die 15 presses down with the top plate 17 to punch and cut the adhesive film 4, punching the double-sided adhesive 2 until the release film or release paper 1 is half-cut. The sheet-like adhesive film 4 formed by punching is attached to the dustproof net 3 by its own adhesiveness.

[0045] After the bonding is completed in step S3, the whole product continues to be conveyed. During the conveying process, the waste removal tape 19 is pasted on one side of the whole product. Specifically, part of it is pasted on the double-sided tape 2 that has not been punched on one side, and the other part is pasted on the edge of the dustproof net 3. When the waste removal tape 19 is wound up, the waste removal tape 19 uses its own adhesiveness to peel the useless part of the top coating and the dustproof net 3 from the release film or release paper 1. After peeling, it is conveyed to the winding paper tube 23 to complete the winding. After the winding paper tube 23 is wound up, the machine can be paused and the product can be cut with scissors for the transport of the roll.

[0046] Any adaptive changes made according to actual needs are within the scope of protection of this invention.
