Blow-Fed Blind Rivet Nut Rivet Bolt Setting System

Blind rivet nuts and bolts are commonly used to create a threaded connection in materials where it’s difficult or impossible to access the back side, such as sheet metal and other thin materials. Using our setting system with force-displacement measurement for the automatic installation of blind rivet nuts and bolts can significantly improve pick and place automation efficiency and precision. 

Benefits include: 

  1. Speed and Efficiency. With a total cycle time of just 8 seconds, our automated feed system loads and positions blind rivet nuts and bolts much faster than manual methods. This increased speed translates into higher production rates, reducing assembly time and labor costs.
  2. Consistency. The automated process for setting blind rivet nuts is monitored 100%. This ensures blind rivet nuts and bolts are consistently positioned and inserted with the same force and accuracy — critical for maintaining the quality and integrity of the assembly.
  3. Reduced Human Error. Human error, such as misalignment or incorrect insertion, can be minimized or eliminated with automated systems. This reduces the likelihood of defects and rework.
  4. Improved Ergonomics. Automation can reduce the physical strain on workers by handling repetitive and physically demanding tasks. This can lead to a safer and more comfortable working environment.
  5. Integration with Quality Control. Automated systems can be integrated with quality control mechanisms, such as sensors and cameras, to inspect the inserted blind rivet nuts and bolts for proper alignment and depth. Defective parts can be identified and addressed immediately.
  6. Versatility. The feed system is programmable and can accommodate various sizes and types of blind rivet nuts and bolts. This flexibility allows it to be used in a stationary setting or in transfer systems, rotary table systems, and robot systems. 
  7. Data Logging. Data related to the insertion process, such as the number of rivet nuts inserted, the time taken for each insertion, and any deviations from the expected parameters, is recorded. This information can be valuable for process optimization and quality control.
  8. Continuous Operation. Automated systems can operate continuously without the need for breaks, leading to higher production uptime. The blind rivet nuts are singulated in a feed system as bulk materials and automatically feed into the correct position via a flexible feed hose in relation to the setting unit.
  9. Reduced Material Waste. Automated systems can be set up to minimize the waste of blind rivet nuts by accurately positioning and inserting them, reducing the likelihood of damage or misplacement.
  10. Cost Savings. The compact design, with a closed housing to protect against dust, and the quick tool change underline our commitment to economic feasibility. Long-term cost savings in terms of reduced labor costs, increased production rates, and improved quality can be significant.
