Description

Technical Field

[0001] This application relates to the field of PCBA board processing technology, and in particular to an automatic flipping and dispensing device for PCBA boards. Background Technology

[0002] PCBA, short for Printed Circuit Board Assembly, is a complete circuit system formed by mounting electronic components (such as SMT surface mount components and DIP through-hole components) on a PCB (printed circuit board) through processes such as soldering. PCBA board dispensing equipment mainly consists of dispensing valves, pressure tanks, piping systems, control systems, and operation panels. The glue is heated in the dispensing valve and extruded onto the PCBA board through a glue gun.

[0003] Patent document CN118305043B discloses a PCB circuit board dispensing device, comprising: a conveyor; a dispensing gun mounted on an assembly box; and a spreading block; the dispensing gun is driven by a three-axis displacement stage to descend onto the PCB circuit board on a pad, the spreading block first contacts the PCB circuit board, and then as the dispensing gun continues to descend, it drives several spreading blocks to converge through a transmission component. After dispensing, the dispensing gun rises and, through the transmission component, drives several spreading blocks to spread the glue, enabling the glue to be spread out immediately and automatically after dispensing. This avoids the problem of uneven glue distribution when bonding electronic components due to the accumulation of water droplets of glue at the dispensing position when the glue volume is large. Furthermore, the glue can be spread without shaking the PCB circuit board, without affecting the stability of the PCB circuit board clamping. The area where the glue is spread is the range of the spreading block diffusion path, preventing glue from flowing out of the dispensing area.

[0004] However, the aforementioned patent documents are not convenient for quickly flipping and dispensing adhesive on both sides of the PCBA board during use, which reduces processing efficiency. Therefore, we propose an automatic flipping and dispensing device for PCBA boards to solve the above problems. Utility Model Content
