Spring Automatic Loader mainly falls into two types: one is a **screw spring loader for conveying powdery and granular materials**, and the other is automated equipment for **feeding spring parts themselves**. The former is the more common type on the market, mainly used for the automatic conveying of plastic powders and granules.

Bulk springs are poured into the bowl, and vibration of the vibratory bowl drives the springs upward along the spiral track; tangled springs enter the separator to be loosened and separated; track screening removes springs with incorrect orientation and stacked springs; qualified springs enter the linear vibratory track in a single row; after the sensor detects them in position, a cylinder separates them, and each single spring is delivered through the spring guide tube to the assembly station — automatic refilling when short and pause in feeding when full.
A spring automatic loader mainly achieves automatic sorting, separation and single-piece feeding of compression springs, torsion springs and tower springs, docking with downstream assembly, press-fitting, riveting and inspection equipment — replacing manual spring placement. It is widely used in hardware, electronics, home appliances, automotive and medical device industries:
1. 3C Electronics Industry
Automatic assembly of small compression springs and torsion springs inside mobile phones, earphones, connectors and keys
Spring feeding for connector assembly machines, switch assembly machines and terminal assembly equipment
Micro springs, mostly paired with vibratory bowl separators or flexible vision loaders
2. Automotive Parts Industry
Automatic feeding of springs for door lock assemblies, seat mechanisms, seat belt components and small brake parts
Spring press-fitting for valves, solenoid valves, small fuel injection parts and wiring harness connectors
Mostly paired with multi-station servo press-fitting machines and dedicated assembly lines
3. Home Appliance Industry
Spring assembly for switches, relays, thermostats, shower heads, door locks and stove accessories
Automated assembly lines for internal hardware components of washing machines and small appliances
4. Hardware and Tools Industry
Automatic spring feeding and assembly for lock springs, fasteners, tool accessories and hinge springs
Supporting equipment for lighter and sanitary hardware accessory assembly
5. Medical Devices
Micro spring assembly for syringe components, small instrument accessories and medical switches
Flexible vision feeding is mostly used to reduce spring scratching and coating damage
6. General Automation Equipment Support
Servo press-fitting machines and hydraulic press-fitting machines: springs are automatically fed into the mold to complete press-fitting
Multi-station rotary equipment: each station is supplied with springs automatically
Riveting machines and dispensing-assembly integrated machines: integrated automatic spring feeding and assembly
Spring inspection and sorting equipment: automatic spring feeding for dimension and spring force inspection
7. Other Applications
Automatic assembly of various small springs in the toy industry
Internal spring assembly for pneumatic and hydraulic valves
