Equipment parameters

I. Industry Application Background of Online Visual Dual-liquid Dispensing Machine

In the fields of new energy electronics, automotive electronic control, industrial control modules, and precision sensing equipment manufacturing, most sealing, encapsulation, and bonding processes use two-component AB adhesives. These adhesives are mixed precisely by A and B components to achieve insulation, waterproofing, shock resistance, and reinforcement protection effects for the products. Traditional single-liquid dispensing equipment cannot be adapted to the operation of two-component adhesives. Ordinary dual-liquid dispensing machines rely on fixture positioning and offline single-machine operation, which have problems such as positioning deviation, imbalance in mixing ratio, uneven mixing, and inability to connect with the assembly line. The manual mixing and coating mode is prone to errors in proportion, insufficient mixing, and inconsistent curing effects, easily causing quality risks such as product delamination, water leakage, and insulation failure in the later stage. The online visual dual-liquid dispensing machine integrates CCD visual intelligent positioning technology, dual-liquid precise mixing system, and online assembly line structure to achieve automatic mixing, blending, visual correction, and continuous online dispensing of two-component adhesives. It is suitable for high-precision, large-scale, and continuous dual-liquid process production requirements and is the core equipment for the intelligent upgrade of dual-liquid encapsulation processes.

II. Integrated Structure and Online Operation Principle of the Equipment

The online visual dual-liquid dispensing machine adopts an integrated integrated assembly line structure, integrating conveying line body, visual recognition module, dual-channel independent supply system, dynamic mixing mechanism, and servo motion control system. The overall structure is compact and regular, without the need for additional auxiliary equipment, and can directly connect with the upstream and downstream production processes of the factory and integrate into the closed-loop of the automated production line. The equipment abandons the traditional offline single-machine operation mode. The workpiece automatically feeds along the assembly line and flows at a constant speed, without the need for manual positioning. Relying on integrated linkage control, the conveying, visual scanning, mixing and dispensing, and material discharge circulation processes are coordinated and connected without waiting periods, effectively improving the overall throughput efficiency of the production line. The frame adopts a rigid reinforcement design, ensuring strong stability during high-speed operation, effectively avoiding jitter and deviation problems, and guaranteeing consistent process accuracy in long-term mass production conditions.

III. Dual-liquid Independent Supply, Precise Mixing Process

Dual-liquid precise dispensing control is the core function of this equipment. The equipment is equipped with two independent sealed storage tanks and precise metering conveying mechanisms for A and B adhesives. The A and B adhesives are stored separately and pumped independently, avoiding premature mixing and drying of the adhesives and pipe blockage from the source. The system can flexibly adjust the dual-liquid mixing ratio according to different adhesive process requirements and adapt to various conventional dual-component epoxy resins, polyurethanes, and organic silicon encapsulation adhesives. The precise metering pump supplies adhesives at a stable speed, with the mixing error controlled within a reasonable range, eliminating problems such as incomplete curing, softening of the adhesive, cracking, and color change caused by proportion imbalance. After the adhesives are delivered to the dynamic mixing mechanism, they are uniformly fused through high-speed stirring to ensure consistent material quality and uniform curing performance in each coating area, effectively improving the sealing and protection quality of the product.

IV. CCD Visual Positioning, Precise Correction and Dispensing without Fixture

The equipment is equipped with a high-definition industrial CCD visual recognition system, relying on intelligent image algorithms to complete automatic recognition of the workpiece, position correction, and trajectory planning, completely摆脱ing the reliance of traditional equipment on precise fixture and jig. During assembly line operation， even if the workpiece has slight placement deviation， angle deviation， or incoming material tolerance， the visual system can collect data in real time and dynamically compensate the dispensing trajectory to ensure that the coating position precisely meets the process standards. It can accurately identify complex areas such as irregular structures， arc-shaped borders， fine gaps， and micro points， and adapt to various precision processes such as chip filling， border sealing， cavity encapsulation， and pin reinforcement. The automatic visual correction mode effectively addresses the industry pain points of inaccurate manual positioning， single-appropriate fixture adaptation， and difficult point dispensing of complex workpieces， significantly reducing the defect rate of dual-liquid dispensing. 

V. Continuous Assembly Line Operation， Enhancing Flexibility in Mass Production Online production line operation mode supports dynamic tracking of workpieces during dispensing, eliminating the need for stoppages for loading and unloading, enabling 24-hour continuous production cycles, and significantly enhancing equipment utilization and overall production capacity. The operating speed of the equipment can be freely adjusted, suitable for different production line cycle times and capacity requirements, and compatible with small-batch multi-category trial production and large-scale regular mass production. The intelligent control system can store multiple sets of double-gel ratio parameters and visual trajectory schemes. When changing products for production, preset parameters can be quickly retrieved for quick production changeover, eliminating the need for repeated adjustment of ratios and trajectories, effectively reducing production changeover time and adapting to flexible alternate production modes. The fully automated operation significantly reduces manual intervention, reduces process errors caused by manual operation, and enables the double-gel production process to achieve standardized and standardized control.

Six. Intelligent maintenance design, reducing production loss costs

The equipment adopts modular integrated design, with a clear structure layout, low failure rate, and suitable for high-intensity continuous mass production conditions in workshops. Components such as double-gel pipelines, mixing heads, and dispensing nozzles are easy to disassemble and assemble. The equipment is equipped with an automatic cleaning function, and after operation, residual mixed gel in the pipelines can be quickly cleaned to avoid gel drying and clogging of the pipelines, extending the lifespan of components and reducing maintenance costs. The system comes with shortage warning, pressure self-check, and trajectory abnormality alert functions, which can monitor insufficient supply of gel, pipeline blockage, and identify abnormalities in real time, promptly alerting staff to troubleshoot and avoid batch production defects. Precise ratio and dispensing control systems can effectively reduce gel waste, improve material utilization, and help enterprises control production costs in long-term mass production.

Seven. Adaptation to industries and equipment application value

The online visual double-gel dispensing machine is widely used in dual-component gel encapsulation processes in fields such as new energy power module, automotive electronic components, industrial control circuit boards, intelligent sensing equipment, outdoor lighting drives, and precision electrical components. Due to the strict ratio requirements, high curing requirements, and difficult precision control of the double-gel process, this equipment combines visual intelligent correction, precise double-gel ratio control, and online efficient mass production advantages to solve the industry problems of low precision, slow efficiency, cumbersome production changeover, and unstable product yield of traditional double-gel equipment. In the process of intelligent upgrading of manufacturing, the equipment can effectively improve product encapsulation quality and production efficiency, reduce rework costs and material losses, help enterprises complete the automation and refinement upgrade of the double-gel dispensing process, and provide reliable automated solutions for various precision coating and encapsulation production of dual-component gels.
