Description

Technical Field

[0001] The invention relates to the technical field of SMT placement machines, and in particular to a feeding structure of an SMT placement machine. Background Art

[0002] SMT placement machine, short for placement machine, is an automated device used in electronic manufacturing to accurately place electronic components on PCBs. It plays a very important role in modern electronic manufacturing, especially in large-scale production. The placement machine can achieve high-speed precise positioning and placement of components, handle multiple types of components and PCBs, achieve very high precision, ensure the correct placement of components, and reduce human errors and scrap rates.

[0003] The placement machine provides electronic components through a feeding system, and these components are usually provided in the form of strips or discs. These systems can quickly and accurately provide electronic components of various types and sizes to meet the requirements of different PCBs. However, there are some problems in the existing placement machine feeding system when assembling the feeder (feeder): the feeder (feeder) usually needs to be replaced or adjusted regularly to adapt to components of different types and sizes, but the existing feeding system structure design is relatively complicated and time-consuming for the disassembly and reinstallation of the feeder; the accurate position of the feeder is crucial to the placement process because it directly affects the precise placement of the components. However, the existing structure lacks an effective debugging mechanism, making it difficult to adjust the position of the feeder, and lacks a stable support structure for the feeder. If the position of the feeder is unstable or the support is insufficient, it will cause the placement accuracy to decrease or the machine to fail. Therefore, the present invention proposes a feeding structure for an SMT placement machine to solve the problems mentioned in the above background technology. Summary of the invention
