Description

Technical Field

[0001] This invention relates to the field of double-sided tape die-cutting technology, specifically a novel die-cutting manufacturing process. Background Technology

[0002] With the development of electronic products, die-cut products are being used more and more widely in the electronics industry. In the die-cutting process of electronic products, non-stick tear handles are added to double-sided adhesive products according to customer needs. In the traditional die-cutting production process, there are two solutions: 1. One-step punching and manual waste removal; 2. Two-step positioning punching and machine waste removal.

[0003] One-step punching and manual waste removal:

[0004] It requires the addition of auxiliary materials such as a base film and a light release film. After the finished product is made, the waste material from the torn handle and outer skin needs to be manually removed and then transferred to the light release paper. This process has low productivity, high labor intensity, and high cost due to manual waste removal.

[0005] Waste removal from two-step punching machine:

[0006] The bottom layer of the double-sided adhesive is attached to the heavy release film and contains the original release paper. A partial punching and tearing handle is made on one side of the original release paper to cut off the double-sided adhesive. The area of ​​the heavy release film exposed after tearing off the double-sided adhesive and the original release paper at the punching position is the tearing handle. The original release paper attached to the double-sided adhesive is then removed and replaced with light release paper.

[0007] A support frame is fixedly connected to the upper surface of the tooling table. A push cylinder is installed at the top of the support frame. A fixed plate is fixedly connected to the upper part of the front facade of the support frame. A telescopic mechanism two is installed on the front facade of the fixed plate. A pressure cylinder is installed on the front facade of the telescopic mechanism two. An mounting plate one is installed at the middle of the front end of the support frame. A telescopic mechanism three is installed on the front facade of the mounting plate one. The sliding end of the telescopic mechanism three is installed with the mounting plate one. A front plate is installed at one end of the mounting plate one. The front facade of the front plate is fixedly connected to the telescopic mechanism one. A pressure block is installed on the sliding end of the telescopic mechanism one. A slide rail is fixedly connected to the upper surface of the tooling table on the left side. A slider is slidably connected to the upper surface of the slide rail. A placement platform one is fixedly connected to the upper surface of the slider. A placement platform two is installed on the upper surface of the slider on the right side. A connector is installed on the driving end of the push cylinder. A fixing frame is fixedly connected to the bottom end of the connector. A base plate is fixedly connected to the lower surface of the fixing frame. An electric push rod is installed in the center of the upper surface of the tooling table. The telescopic end of the electric push rod is installed on the lower surface of the placement platform one.

[0008] Reverse the material strip, place the release film face up on the die-cutting machine for the second step of positioning and punching, cutting to the double-sided adhesive layer. After the first cut, the material strip moves the double-sided adhesive backward by the required width of the double-sided adhesive and punches again. After the second cut, the material strip moves the double-sided adhesive backward by the interval and cuts again. This cycle continues.

[0009] This process increases the need for machines, labor, and auxiliary materials. The second step, punching the positioning holes, is prone to damage, leading to a high defect rate, significantly increasing costs, and posing a huge risk. Summary of the Invention

[0010] The purpose of this invention is to provide a novel die-cutting manufacturing process to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, the present invention provides the following technical solution:

[0012] A novel die-cutting manufacturing process includes:

[0013] The product roll film includes double-sided adhesive and a tear handle end is provided on the double-sided adhesive. The upper surface of the double-sided adhesive is bonded with original factory release paper, and the original factory release paper is provided with double-sided adhesive and has a round hole. The lower surface of the double-sided adhesive is bonded with light release paper.

[0014] Die A and die B are used for cutting. Die A cuts from the light release paper towards the original factory-supplied release paper, while die B cuts from the original factory-supplied release paper towards the light release paper.

[0015] As a further aspect of the present invention: both the light release paper and the original factory-supplied release paper are provided with raised edges that correspond to and are adapted to the tear handle end of the double-sided adhesive.

[0016] As a further aspect of the present invention: the B die is provided with a cutting head for punching the round holes on the release paper.

[0017] As a further improvement of the present invention, the specific process is as follows:

[0018] S1: Double-sided adhesive adheres to the light release paper through its bottom adhesive, forming a material strip;

[0019] S2: Use die A to cut from the light release paper surface and punch to the original release paper surface;

[0020] S3: Use the B die to cut into the original release paper and punch it to the light release paper. At this point, the small holes are completely broken.

[0021] S4: After the cutter makes the first cut, the material belt moves the double-sided tape backward to the required product width distance of the double-sided tape and then punches it again.

[0022] S5: After the cutter makes the second cut, the material strip moves backward along the double-sided tape at intervals and cuts again;

[0023] S6: Repeat this process to cut out the finished double-sided tape handle, and remove the outer waste material from the machine and rewind it.

[0024] S7: Reverse the double-sided tape and remove waste material from the handle area on the laminating machine.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. In this invention, die A cuts half of the tear handle on the double-sided tape onto the original release paper, while die B directly cuts half of the finished product onto the light release paper. That is, with the cooperation of dies A and B, double-sided tape with a tear handle is directly cut out, resulting in high production capacity, high efficiency, and stable reliability.

[0027] 2. This invention directly removes outer waste material on the machine. Furthermore, after reversing the double-sided tape, only one handle tearing is required to remove waste. Waste removal is simple and quick, reducing manual labor and significantly saving costs. No additional auxiliary materials are needed for waste removal, resulting in a substantial reduction in labor and raw material costs. Attached Figure Description
