Multi-step tightening demonstration of the Sensewee servo screwdriver
2019-01-21
As technology is updated and upgraded time after time, the products being manufactured are becoming increasingly sophisticated and compact. Take mobile phones as an example: in the 1990s, "big brother" cell phones were all the rage, yet many people jokingly referred to them as "big bricks." But today, mobile phones are no longer the bulky brick-like devices of yesteryear—they’ve become incredibly thin and lightweight, to the point that the concept of “paper-thin” phones has even been proposed recently.
However, each time a new product is launched, it places new demands on technological processes.
So, what exactly is this so-called technological process nowadays?
Let’s briefly touch on screw-fastening as a breakthrough in automation.
Take the single screw-fastening process as an example: Currently, handheld electric screwdrivers remain the mainstream method for tightening screws. Most screw-fastening workstations still rely on manual labor, making them prone to abnormalities such as missed fastenings and stripped threads. This technology can no longer meet the tightening requirements of the vast majority of electronic products on the market.
Take the example of tightening a mobile phone circuit board: If you keep applying force continuously without pause, you might end up damaging the circuit board. In such cases, it’s essential to adopt a multi-step tightening approach—first screwing in the fasteners and then reversing them out again. The purpose is not to lock them down immediately. If you were to lock them down right away, subsequent tightening operations could potentially damage the circuit board. Therefore, instead of starting with a full torque right from the beginning, you should leave some slack initially. Once all the screws are roughly secured, you can proceed with the final tightening step. This approach ensures that the product’s tightening requirements are met efficiently.
However, not all electric screwdrivers are capable of performing this multi-step tightening process. Some might argue that manual labor could also handle such multi-step tightening. Indeed, it’s possible to do it manually—but in terms of efficiency and precision, manual methods would fall far short. After all, the screws used in smartphones are inherently quite small; asking human workers to tighten them over a prolonged period would simply not be practical.
The Sensewee servo electric screwdriver can efficiently solve this problem. Equipped with imported servo motors and drivers, and featuring a dedicated servo control algorithm, the Sensewee servo electric screwdriver offers significant advantages over conventional screwdrivers that use DC and stepper motors in terms of tightening consistency and service life. It not only provides screw-tightening functionality but also includes features such as tightening programming, pass/fail statistics, result analysis, record traceability, and data interaction. It comes with 16 task modes, and each task can be divided into up to 5 steps, making it fully adaptable to a wide range of complex tightening processes.
