Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to an automatic feeding mechanism for PCB circuit board processing. Background Technology

[0002] With the rapid development of the electronics industry, electronic products are becoming increasingly integrated, the component density on circuit boards is increasing, and the wiring on circuit boards is also becoming more dense. PCB circuit boards are widely used in electronic products. Currently, the production process of PCB circuit boards usually adopts automatic feeding by robotic arms, thereby improving the production efficiency of PCB circuit boards.

[0003] A search revealed that patent application CN217569424U discloses an automatic dispensing machine for circuit board processing with automatic feeding function, comprising a base, a motor installed on the inner side of the bottom wall of the base, a bracket installed on the top of the base, an electric telescopic rod installed on the front of the bracket, a glue feeder installed on one side of the base, and a support plate installed on one side of the bracket. By pushing the assist block, glue can be easily dispensed onto the circuit board, improving the dispensing effect.

[0004] However, due to the setup of the workbench, the staff needs to manually place the circuit board on top of the workbench, which is time-consuming and labor-intensive. It does not have an automatic feeding function, has a low degree of automation, and poor performance. At the same time, when dispensing glue to the circuit board, the circuit board is prone to displacement, and it cannot be limited, which affects the dispensing effect and makes it inconvenient to position and limit the circuit board.

[0005] Therefore, we propose an automatic feeding mechanism for PCB circuit board processing. Utility Model Content
