Screwing household appliances usually requires the use of specialized electric screwdrivers or automatic screwdrivers. In the manufacturing and maintenance process of household appliances, screwing is a common step. To ensure the tightness and efficiency of screws, electric screwdrivers or automatic screwdrivers are usually chosen. These tools can quickly tighten or loosen screws, greatly improving work efficiency. ?
Definition and core tools for screwing household appliances
Screwing household appliances is a process of assembling screws using an electric screwdriver or automatic screw machine, with the core goal of improving screw tightening efficiency and consistency. The main tools include:
?
Electric screwdriver: adaptable to different screw specifications, providing adjustable torque to avoid slipping or over tightening issues; ?
Automatic screw machine: Integrated feeding system and tightening module, realizing automatic sorting, conveying, and locking of screws. ?
??
Process flow and quality control
Material supply and positioning:
The vibrating disc or air blowing feeding system arranges and transports the screws to the locking position, ensuring the correct direction of the screws through optical/mechanical sensors; ?
The suction nozzle or guide tube of the automatic screw machine accurately positions the assembly holes of screws and electrical components. ?
Lock payment execution:
?
Electric screwdriver or servo driven tightening gun completes locking according to preset torque and angle, with built-in sensors for real-time monitoring of tightening status; ?
Abnormal detection (such as missing locks, slipping teeth) triggers alarms and suspends operations to reduce the rate of defective products. ?
Quality verification:
?
The finished product needs to be verified for screw tightness through a torque tester to ensure compliance with the structural strength requirements of household appliances. ?
??
Technical advantages and applicable scenarios
Efficiency improvement: The single piece locking cycle of the fully automatic screw machine can be shortened to a few seconds, suitable for large-scale home appliance production lines; ?
Compatibility extension: Supports multi scenario applications from micro screws (such as circuit board fixation) to large screws (such as shell assembly); ?
Cost optimization: Reduce material waste and manual intervention through functions such as screening irregular screws and automatic material replenishment. ?
