Mountz Guide: Eliminate the Problem of Missing Screws with Batch Count Functionality

In complex fastening operations with numerous screws and rapid production lines, missed screws can compromise product quality. Implementing batch counting and line control functionality helps ensure accuracy right from the start.

Common Challenges and Solutions

Challenge: On fast-paced assembly lines, operators may miss fastening screws.
Solution: Implement screw counting capabilities with an operator feedback system to ensure every screw is accounted for.

Challenge: Operators traditionally need to mark each screw to verify fastening.
Solution: Utilize screw counting and line control features. Once all screws are secured, the screwdriver signals the line to proceed with the next batch.

The Benefits of Screw Counters

Screw counters are essential for detecting and preventing costly errors in screw fastening during the assembly process. These devices act like the vigilant eyes and ears of a quality control manager, stationed at the assembly point to verify that all fasteners are installed correctly and tightened to the specified torque. By automating this verification process, screw counters reduce the likelihood of human error.

Designed to identify issues such as cross-threading, missed screws, incomplete rundowns, and unfinished cycles, screw counters ensure that the assembly process is correctly executed the first time. They typically work in conjunction with electric or pneumatic screwdrivers and may be integrated with torque control systems. The advanced functionality of screw counters allows them to "learn" the characteristics of both the tool and the application, distinguishing between properly seated fasteners and those that are stripped or cross-threaded.

The Importance of Error Prevention

Fastening errors can significantly impact the bottom line. Errors may lead to catastrophic failures, which are usually obvious and easier to manage, or latent failures, which are harder to detect and may cause issues after the product has reached the customer. Latent failures can be especially costly, as they often result in field failures that damage the product's reputation and incur higher costs for repairs.

The screw counting process aims to ensure that all screws are secured during assembly, catching errors early to avoid costly rework. Detecting an error at the assembly stage allows operators to fix the issue immediately or prevent defective products from advancing down the line. If an error goes undetected and is passed to subsequent stations, the cost of correction increases, whether it involves additional labor to dismantle and retighten components or the use of designated rework areas.

Key Features to Look For

When choosing a screw counting system, consider units that provide both audible and visual indications of completion or rejection. A good system will display the type of fastening error and store multiple fastener settings for different applications. Look for models that can integrate with PLC systems for enhanced line control and offer features like password protection to prevent unauthorized changes. A compact design with mounting brackets is also beneficial for easy integration into the production workspace.

Mountz Screw Counting Solutions

Mountz offers several screw counting solutions, including the Scout screw counter, which works with Mountz electric screwdrivers and specific power supply units. The BLG-BC1 series feature built-in screw counters.

By incorporating screw counters, manufacturers can enhance production yields, reduce costs, improve product quality and reliability, and protect their brand reputation. These systems ensure every assembly undergoes thorough quality control right on the assembly line, safeguarding against errors that could lead to significant repercussions.
