Adhesive Cobot Raises Productive Time 20% in Frame Assembly

The production constraint

A French manufacturer assembling glued structural frames relied on fitters to hold a profile in one hand and a glue gun in the other. The bead had to land in the right place, in the right quantity, and in a repeatable pattern.

That method was repetitive, messy and physically taxing. Continuous trigger pressure contributed to wrist discomfort and musculoskeletal risk, while imprecise deposition created adhesive loss and prolonged the cleaning that followed assembly.

The operation needed higher throughput without sacrificing sealing accuracy, operator safety or the fit of the existing workshop.

• Reduce repetitive glue-gun handling and operator strain
• Deposit adhesive with consistent position, pattern and quantity
• Limit material loss and the cleanup burden
• Preserve a compact, operator-accessible workstation

A compact cell built around the work

The deployment centered on a table-mounted collaborative arm, a locating fixture and a cartridge-fed dispensing tool. The assembler loaded four profiles, pressed a button, and a cylinder fixed the parts in position before the programmed adhesive path began.

Selection followed the process demands: accurate dispensing, safe proximity to the assembler, a compact footprint and compatibility with the familiar adhesive cartridge. The integrator guided design, customization, installation and operator training, so the cell arrived as a production method rather than an isolated machine.

Work was divided deliberately. The cobot handled the strenuous, dirty dispensing task while the fitter loaded parts, launched and supervised the cycle, then concentrated on precise assembly. Routine service demands were limited largely to replenishing adhesive.

• Define the bead pattern, dose and part-location requirements
• Fit the dispensing cell into the existing workstation
• Program repeatable paths and lock each profile before application
• Train assemblers to load, start and supervise the cell
• Support production continuity through cartridge refills and light upkeep

More useful labor, far less cleanup

The published case reports capacity of up to 110 glued frames per day. Compared with the prior manual operation, productive operator time improved 20% as fitters shifted attention toward higher-value positioning and assembly work.

Cleanup time after assembly fell 50%. More controlled adhesive placement also reduced material loss, while operators no longer spent hours maintaining pressure on a glue-gun trigger.

The operating rhythm mattered as much as the headline metrics. Adhesive dried while the fitter assembled preceding frames, allowing robotic dispensing and skilled assembly to proceed in parallel.

What this pattern means for US manufacturers

This documented deployment was not performed by Service Robot Co. It shows why adhesive dispensing is a strong candidate for a commercial robot pilot program: the task is repetitive and ergonomically difficult, yet the operator remains essential for loading, judgment and assembly.

Service Robot Co. is a full-service, OEM-neutral commercial robot integrator for US businesses. We select equipment across manufacturers, then finance, deploy, integrate, train and service it through a nationwide US engineer network, giving customers a vendor for the full operating lifecycle.

For teams considering collaborative robot arm rental or cobot rental for manufacturing, that model brings selection and robot deployment and integration under the same accountable relationship. Robot leasing for business, monthly payment programs and maintenance included can also align adoption with operating needs, subject to the chosen program.
