Description

Technical Field

[0001] The utility model relates to the technical field of carrier tapes, and particularly relates to a trimming device for semiconductor carrier tape manufacturing. Background Technique

[0002] A carrier tape refers to a strip-shaped product applied in the field of electronic packaging. It has a specific thickness, and holes (also known as pockets) for accommodating electronic components and positioning holes for indexing and positioning are equally distributed in its length direction. The carrier tape is mainly applied to the electronic component mounting industry. It is used in combination with a cover tape to carry and store electronic components such as resistors, capacitors, transistors, and diodes in the pockets of the carrier tape, and a closed package is formed by sealing the cover tape above the carrier tape to protect the electronic components from being contaminated and damaged during transportation;

[0003] Chinese authorized invention: CN216099070U discloses a carrier tape trimming device, which includes a base. A workbench is horizontally arranged on the base, a trimming assembly is arranged on the workbench, and two grinding assemblies for grinding the sides of the carrier tape are also arranged on the workbench. The two grinding assemblies are respectively located on both sides of the carrier tape, and the two grinding assemblies are arranged side by side in the width direction of the carrier tape. A conveying assembly for conveying the carrier tape is arranged on the base. The grinding assembly is located on one side of the trimming assembly along the length direction of the carrier tape, and the conveying assembly is located on the side of the grinding assembly away from the trimming assembly. The utility model provides a carrier tape trimming device, which can cut off the redundant tape edges on both sides of the carrier tape and grind the two sides of the carrier tape, so that the two sides of the carrier tape are flat and there are no redundant tape edges, thereby improving the quality of subsequent processing and further improving the overall processing quality of the carrier tape;

[0004] However, there are still certain problems with its device. During actual use, the device drives the pressing plate to move downward through the first air cylinder, and then drives two fixed cutting knives to synchronously trim the two sides of the carrier tape. However, the distance between the two cutting knives is fixed and non-adjustable. Due to the fixity of the cutting knife distance, the device is unable to cope with the cutting tasks of carrier tapes with different widths. When cutting carrier tapes with a narrower or wider width, due to the non-adjustable cutting knife distance, problems such as unsmooth edges and large width deviations may occur, which may lead to unqualified trimming quality, thereby affecting the overall quality of the carrier tape and the subsequent use effect. In addition, the design of the fixed cutting knife also limits the use range of the equipment, making it difficult to adapt to diverse production requirements and reducing production efficiency and flexibility. Therefore, we propose a trimming device for semiconductor carrier tape manufacturing to solve the above problems. Content of the Utility Model
