In automated assembly, the cleanliness of screws has a significant impact on assembly quality. If screws are contaminated with dirt, oil, or impurities, it can not only affect the transmission of tightening torque but also cause quality issues such as short circuits in electronic products. Danikor's automatic screw feeder provides a comprehensive cleaning solution to ensure the cleanliness of screws during the assembly process.

Hopper Pre-Screening: Controlling Particulates at the Source

Danikor's stepwise screw feeder features a hopper structure without a vibration source, avoiding the issue of metal shavings generated by mechanical vibration and screw friction in traditional vibratory feeders. The hopper is equipped with a standard dust collection box to collect scattered dust and shavings. It also comes with a vacuum adsorption component to remove residual particles in real-time, effectively preventing secondary contamination.

Track Conveyance: In-Depth Cleaning of Individual Screws

During the track conveyance stage, Danikor's screw feeder uses an independent cleaning module to perform in-depth cleaning on individual screws. The track is equipped with built-in brushes or air flow devices to remove stubborn dirt from the screw threads. For scenarios with heavy oil contamination, a solvent spray device can be optionally installed for pre-cleaning. In addition, the system optimizes the positioning accuracy and conveyance speed of the screws to ensure that the cleaning actions are synchronized with the conveyance rhythm, avoiding incomplete cleaning.

Post-Separation Vacuum Dust Removal: Precision Processing

After the screw separator completes the sorting of screws, the system adds an independent vacuum dust removal module. Using negative pressure adsorption technology, it performs directional suction on the surface of individual screws to remove residual dust and fine particles. This module can also adjust the adsorption strength according to the screw material to prevent surface coating damage.

Dynamic Adsorption During Tightening: Ensuring Final Cleanliness

In the tightening stage, the screw suction tube works in conjunction with the tightening module. The suction tube is equipped with a miniature filter device that can capture surface dust while adsorbing screws. Some models also support compressed air blow-off functions to further remove impurities from the screw thread grooves. In addition, the system monitors the tightening torque data in a closed-loop manner, which can indirectly reflect the surface condition of the screw. If the torque fluctuates abnormally, it may indicate the presence of unremoved foreign matter on the screw, triggering a shutdown inspection mechanism.

Extended Functions for Diverse Scenarios

Danikor's automatic screw feeder cleaning solution also provides flexible extended configurations to meet the needs of different industries. In addition, the system supports QR code traceability functions to record the cleaning parameters and quality inspection results of each batch of screws, providing data support for process optimization.

Danikor's multi-level cleaning solution for automatic screw feeders, through the combination of physical isolation, dynamic adsorption, and intelligent monitoring, achieves full-process clean management from coarse screening to fine processing. This phased and modular design approach not only solves the pain point of traditional vibratory feeders generating shavings but also adapts to the stringent requirements of different industrial scenarios through expandable configurations, providing a stable foundation for automated assembly.
