A screw feeder is a small automatic screw locking machine, which can replace human hands with an automatic mechanism to complete the taking, placing, and tightening of screws. Its action structure can be divided into two parts: feeding device and electric screwdriver. The feeding device is responsible for screening and providing screws, and the electric screwdriver is responsible for taking screws and locking screws. The design of the screw feeder not only improves the work efficiency but also reduces the manual work intensity. According to replace the screwdriver bits and adjust the feeding track, the automatic screw feeder can achieve the purpose of locking multi types of screws by one machine.
Screw feeder can be divided into handheld automatic screw feeder and fully automatic screw feeding machine. The handheld automatic screw feeders have been widely used in the assembly line of small household appliances and electronic products due to small size, lightweight, easy installation, operation and maintenance. Fully automatic screw feeding machine is to install a brushless electric screwdriver on a robotic arm or a multi-axis workbench to realize unmanned monitoring and automatic assembly line operations.
