Description

Technical Field

[0001] The invention relates to the field of carrier tape buffering equipment, in particular to an adjustable carrier tape buffering mechanism. Background Art

[0002] Carrier tape is a plastic carrier widely used in the packaging of electronic components, mainly used for the packaging of electronic components such as resistors, inductors, and capacitors. According to the purpose, carrier tapes are divided into various types such as special carrier tapes for transistors and special carrier tapes for SMD LEDs. The materials of carrier tapes mainly include two categories: plastic (polymer) and paper. Among them, plastic carriers are mainly PC (polycarbonate), PS (polystyrene), ABS (acrylonitrile-butadiene-styrene copolymer resin), etc., while paper carrier tapes have the advantages of good rebound, easy preparation and low cost.

[0003] When the carrier tape is used to package electronic components, the feeding mechanism transports the carrier tape to the inside of the packaging equipment, the electronic components are filled into the grooves on the carrier tape, and the carrier tape is rolled up to complete the packaging of the electronic components.
