Description

Technical Field

[0001] The invention relates to the technical field of glue supply and dispensing equipment, and in particular to a precision screw-type integrated glue supply and dispensing equipment. Background Art

[0002] As key equipment in the field of intelligent manufacturing, glue supply and dispensing equipment are widely used in high-precision manufacturing scenarios such as electronic packaging, medical devices, and aerospace. As industrial products develop towards miniaturization and integration, higher requirements are placed on the accuracy, stability, and efficiency of the dispensing process; traditional pneumatic or peristaltic pump dispensing equipment has been unable to meet the needs of emerging fields such as chip packaging (glue line width <0.1mm) and MEMS sensor assembly (positioning accuracy ±0.005mm) due to its rough flow control and large pressure fluctuations; However, the existing screw-type glue supply and dispensing equipment still has significant technical bottlenecks; traditional glue supply equipment mostly adopts open-loop control or simple closed-loop structure, and cannot dynamically adjust the glue supply pressure and flow in real time; for example, the common plunger pump or gear pump glue supply system lacks a pressure feedback mechanism. When the viscosity of the glue changes or the pipeline resistance increases, it is easy to cause the glue supply pressure to fluctuate by more than ±2MPa, which directly affects the consistency of glue dispensing. Although some equipment is equipped with a pressure sensor, it only starts and stops the motor through a fixed threshold, and cannot achieve dynamic compensation of the PID algorithm, resulting in a pulsation amplitude of more than 15% in the glue supply flow, which is easy to form glue accumulation or glue breakage in the dispensing of precision electronic components; in addition, traditional glue replenishment tanks mostly rely on manual observation of the liquid level. When the remaining amount of glue is lower than the critical value, it cannot automatically trigger the replenishment, and the production line is often stopped due to glue supply interruption. High-pressure pipelines generally use single-layer rubber materials, which are less than 30MPa in resistance to instantaneous pressure shocks, and the inner wall is easily adhered to the colloid to form blockages, which requires frequent disassembly and cleaning, seriously affecting production efficiency; therefore, the above technical problems need to be solved and handled.
