Speaking of inverters, everyone may know that it is a tool used to convert direct current (DC) into alternating current (AC). A vehicle-mounted inverter converts the DC12V direct current from the car's battery into the commonly used AC220V alternating current. In foreign countries, the automotive market is already very mature, and many families enjoy outdoor living, using inverters to convert battery power into household electricity, allowing them to power some household appliances and tools while outside. Although this concept has not yet been fully popularized in China, inverters are gradually becoming an essential companion for cars as a convenient tool for converting DC to AC.

The output power of vehicle-mounted inverters through the cigarette lighter can be 20W, 40W, 80W, 120W, or even 150W. For higher power inverters, they need to be connected to the battery. Connecting household appliances to the inverter's output in the car is just like using them at home. The appliances that can be used with the inverter include: Mobile, laptops, digital cameras, and cameras.

As an electronic product, its internal circuit board and wiring structure are quite complex, and there is a certain risk in converting the car's direct current to the household appliances' alternating current, so high precision is required in assembly. If done manually, not only is the operation cumbersome, but it also cannot fully guarantee the quality of the product.

Additionally, if the product requires secondary processing, the screws that are initially inserted may not need to be fully tightened, and sometimes the screws may only be partially screwed in. In this case, the depth and angle of the screw's entry can only be judged by the worker's experience.

According to our understanding, some manufacturers judge whether the tightening is qualified by checking if the height of the screws is consistent after insertion. Relying on the naked eye for judgment is indeed somewhat forced, while smart screwdrivers can control the locking angle and torque to ensure that all screws can complete the task according to custom requirements, or first fully tighten and then back off the screws to reach the set value. Once the requirements are met, there is no need for manual inspection, which not only improves production efficiency but also ensures product quality, making it a win-win situation.

In every assembly application, locking screws is a necessary step. Using manual labor for locking is already outdated; smart screwdrivers can completely replace manual work and perform tasks better, making them one of the essential devices in the future assembly market.
