Description

Technical Field

[0001] The utility model relates to the field of carrier belt conveying, in particular to a brake structure of a carrier belt conveying device. Background Art

[0002] Carrier tape refers to a strip product used in the field of electronic packaging. It has a specific thickness, and holes for holding electronic components and positioning holes for indexing are evenly distributed along its length. Carrier tape is mainly used in the electronic component mounting industry. It is used in conjunction with a cover tape (upper sealing tape) to carry and store electronic components such as resistors, capacitors, transistors, and diodes in the pockets of the carrier tape, and the cover tape is sealed on top of the carrier tape to form a closed package to protect the electronic components from contamination and damage during transportation. When mounting electronic components, the cover tape is peeled off, and the automatic mounting equipment takes out the components in the pocket one by one through the precise positioning of the index holes of the carrier tape, and mounts them on the integrated circuit board. In order to facilitate later use, the carrier tape will be rolled up and packaged using a carrier tape holder during production.

[0003] However, during the conveying process of the carrier tape, the inertia of the carrier tape holder during rotation makes it impossible to stop rotating in time. This results in the carrier tape being broken if the brake is not applied in time when loosening or rewinding, or the carrier tape being messy due to excessive loosening. At the same time, it is not convenient to lock the carrier tape holder after stopping, which easily causes it to rotate or reverse. Therefore, a brake structure of a carrier tape conveying device is proposed to address the above problems. Utility Model Content
