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.
