Description

Technical Field

[0001] The utility model relates to the technical field of carrier tapes, in particular to a fast-pulling carrier tape buffer mechanism. Background Art

[0002] Carrier tape is a strip-like product widely used in the electronics packaging field. It has a specific thickness and is evenly spaced along its length with holes (also called pockets) for holding electronic components and positioning holes for indexing and positioning. Carrier tape is primarily used in the electronic component placement industry. It is used in conjunction with cover tape (top tape) to carry and store electronic components such as resistors, capacitors, transistors, and diodes in the carrier tape's pockets. The cover tape is then sealed over the carrier tape to form a closed package, protecting the electronic components from contamination and damage during transportation. When placing the electronic components, the cover tape is peeled off, and the automated placement equipment, using the carrier tape's index holes for precise positioning, removes the components from the pockets one by one and places them on the integrated circuit board (PCB).

[0003] Before use, the carrier tape is usually wrapped around a tray. When needed, the carrier tape wrapped around the tray can be pulled. However, since the tray is stationary, excessive force may cause the carrier tape to break when pulled, and the chip may also move due to excessive vibration frequency.

[0004] In view of this, the utility model proposes a fast pulling load belt buffer mechanism. Utility Model Content

[0028] In this embodiment, the force-bearing component 62 includes a connecting plate 621, a connecting shaft 622, a carrier pulley 623 and a rubber ring 624. By setting the force-bearing component 62, when the carrier is pulled, the carrier will contact the carrier pulley 623. When the carrier is pulled, the carrier will drive the carrier pulley 623 to rotate on the surface of the connecting shaft 622 through movement, and thereby drive the buffer swing arm 611 to swing through the connecting plate 621, so as to achieve a buffering effect when the carrier is stretched.

When the carrier belt is pulled, the carrier belt will contact the carrier pulley 623, and when the carrier belt is pulled, the carrier belt will pass through The movement drives the carrier pulley 623 to rotate on the surface of the connecting shaft 622, and thereby drives the buffer swing arm 611 to swing through the connecting plate 621, so as to achieve a buffering effect when the carrier is stretched, and by setting the rubber ring 624, the rubber ring 624 is made of soft material and can play a protective role for the carrier. When the height of the carrier pulley 623 needs to be adjusted, the connecting rod 613 can be slid along the inside of the slide groove 612 to make the slide plate 615 slide inside the buffer swing arm 611, and finally tighten the nut 614.

[0035] By setting the contact block 10, when the connecting plate 621 swings, it will contact the contact block 10 and apply a thrust to it. At this time, the contact block 10 will push the slide bar 8 to slide inside the vertical plate 7 and squeeze the spring 9.
