The 3-axis automatic screwdriver robot is designed for a wide range of screws, replacing manual screw-locking to achieve mechanized production while reducing workers’ labor intensity. Traditionally, manual placement and alignment of screws consume significant time and energy—this automatic screwdriver robot eliminates those inefficiencies. With a user-friendly design, it does not require a handheld teaching device, ensuring quick installation and simple operation settings that workers can easily master and debug. The screw feeding mode can be customized to either suction or blowing types based on customer needs. Its automatic alarm function simplifies maintenance and ensures stable machine parameters. The vacuum suction mode offers high versatility and fewer errors, overcoming the limitations of blowing screws with a length-to-diameter ratio of less than 1.2 and allowing the handling of stainless steel screws that cannot be magnetically absorbed. For quick screw changes, only the feeding component and nozzle need replacement, supporting M1.0-M4.0 screw types. The blowing screw mode, on the other hand, delivers screws directly to the nozzle, eliminating back-and-forth movement for higher efficiency. Suitable for industries such as mobile phones, digital products, optoelectronics, medical devices, and household appliances, this advanced automation solution enhances precision, speed, and reliability in screw-locking applications.
