Description

Technical Field

[0001] This utility model relates to the field of SMT placement machines, specifically an SMT precision component flipping mechanism. Background Technology

PCB stands for Printed Circuit Board, and SMT is an abbreviation for Surface Mount Technology. It is one of the most popular technologies and processes in the electronics assembly industry. In general, the electronic products we use are made up of PCBs with various electronic components such as capacitors and resistors, designed according to the circuit diagram. Therefore, all kinds of electrical appliances require various SMT processing techniques.

[0003] In the AOI inspection stage of SMT process, products need to be inspected on both sides. Manual flipping is inefficient, and there are risks such as material falling out during flipping, and damage and contamination of products. The existing technical solution is manual flipping + mechanical limit, single-arm cantilever flipping, which has defects such as insufficient dynamic rigidity, poor rotation accuracy, inaccurate fixture positioning, unstable operation, risk of material falling out during flipping, and the tray cannot be reused after flipping.

[0004] To address the technical problems described in the background section, this invention provides an SMT precision component flipping mechanism. Through a dual-carrier collaborative flipping mechanism and an automatic switching design for the lower carrier's state, the mechanism achieves carrier function interchange via Z-axis descent and a 180° flip. Eliminating the traditional manual tray changing process improves efficiency. Compared with single-arm flipping and single-tray flipping, it improves stability and accuracy. It also adds a lifting Y-axis and a flipping X-axis to meet the needs of different sized trays for rapid tray changing, realizes fully automatic dual-tray alternating operation, eliminates manual intervention, and solves the problems of poor operating accuracy, component displacement caused by flipping vibration, and complex flipping in existing mechanisms.
