In many actual processes, a vision dispensing machine does not finish simply by dispensing one glue to position. Some workpieces need two glues coordinated\u2014for example, epoxy A\/B components mixed and cured by ratio, or main bonding glue and edge sealing glue applied sequentially. Such needs are hard to meet with a single valve and require a dual-valve or dual-liquid valve solution for synchronous or coordinated dispensing. Understanding the process logic of two-component dispensing is the premise for selecting the right equipment and valve.<\/p>\n\n\n\n

What Is Two-Component and Dual-Valve Synchronous Dispensing<\/h2>\n\n\n\n

Two-component dispensing refers to the process of metering two glues (e.g., A and B components) by a set ratio and then applying them to the workpiece synchronously or sequentially<\/strong>. The main implementation methods are two types:<\/p>\n\n\n\n

One isthe dual-liquid valve<\/strong>(conventional dual-liquid valve), which completes proportional metering and merging of the two glues inside the valve body, suitable for systems requiring mixed curing;<\/p>\n\n\n\n

the other isthe dual valve<\/strong>in parallel, i.e., two independent valve bodies dispensing different glues respectively, suitable for scenarios where main glue and sealing glue are applied stepwise.<\/p>\n\n\n\n

The vision dispensing machine achieves precise spatial and temporal coordination of the two glue paths through vision positioning and motion control.<\/p>\n\n\n\n

Which Scenarios Use Two-Component Dispensing<\/h2>\n\n\n\n

Common cases includeencapsulation and potting of epoxy AB glue, bonding with two-part structural adhesive<\/strong>, and scenarios requiringcomponents where bonding glue is applied first then sealing glue added<\/strong>. In new energy, automotive electronics, and precision modules, such combined processes are not rare. The key to judging whether two-component is needed is whether the glue itself consists of two components, or whether a process must apply two functionally different glues. If it is a single glue type, the single-valve solution is simpler and lower cost.<\/p>\n\n\n\n

How Equipment and Valve Cooperate<\/h2>\n\n\n\n

Two-component solutions demand more from equipment than single valves: two independent glue supply paths, two valve bodies, and motion control that ensures synchronous action. Bolli vision dispensing machines can be configured witha dual-valve structure<\/strong>, combined with Leadshine servos and Xinsheng lead screws to provide a stable platform and motion baseline, allowing the two glue paths to operate under vision guidance perthe preset trajectory in coordination<\/strong>. The specific model and valve combination must be confirmed by Bolli at the selection stage based on workpiece size, glue type, and capacity, to avoid configuration mismatch.<\/p>\n\n\n\n

What to Guard in Ratio and Metering<\/h2>\n\n\n\n

The most critical aspect of a two-component system is ratio stability. Ratio deviation causes problems such as uneven mixing, incomplete curing, or insufficient strength. Conventional dual-liquid valves rely on internal metering structures to output per the set ratio, so glue supply pressure, glue viscosity consistency, and line condition all affect the actual ratio. During production, keep glue batches stable, supply pressure steady, and record key parameters for traceability and review, preventing hidden ratio drift from accumulating into batch defects.<\/p>\n\n\n\n

Key Details of Process Implementation<\/h2>\n\n\n\n

Dual-valve synchronous dispensing also requires attention todispensing timing and the spacing between the two glue paths<\/strong>, and thecuring windows of the two glues conflicting<\/strong>. For example, when applying A first then B, leave reasonable operation and positioning time;synchronous dispensing must prevent the two glue paths from interfering with each other<\/strong>. Bolli vision dispensing machines support editing corresponding dispensing programs by workpiece features, and verify glue shape and bonding effect through sample trials during trial production, locking the process window early to reduce mass-production fluctuation.<\/p>\n\n\n\n

How to Evaluate a Two-Component Solution During Selection<\/h2>\n\n\n\n

Before an enterprise introduces two-component dispensing, it should first sort outglue types, ratio requirements, workpiece structure, and cycle-time targets<\/strong>. If existing single-valve equipment already meets needs, there is no need for blind upgrades; if two-component is truly required, have the supplier combine sample-part trials to confirm metering stability and glue-shape consistency before finalizing equipment. Bolli provides unlimited remote after-sales and sample-trial support, assisting in evaluating whether dual-valve configuration is necessary at the solution stage to avoid over-investment.<\/p>\n\n\n\n

The core of the dispensing machine coordinate system is distinguishing machine coordinates from workpiece coordinates. Machine coordinates use the mechanical origin as the absolute reference of the equipment; workpiece coordinates use the product as reference so programming coordinates match drawing dimensions. The two are linked by origin offset \u2014 resetting the workpiece origin handles product changes. Z-height compensation copes with different product thicknesses, and vision coordinate mapping ties camera to motion through calibration.<\/h2>\n\n\n\n

In summary, two-component and dual-valve synchronous dispensing suit processes requiring two glues or A\/B component coordination; the core lies instable metering ratio and synchronous control of the two glue paths<\/strong>, not all scenarios require it. Enterprises should sort out glue types, ratios, and cycle times before selection, and finalize equipment after verification via sample-part trials, ensuring yield while avoiding over-investment.
