Auto Sear & Dowel Pin Assembly Machine
Auto Sear & Dowel Pin Assembly Machine
The Auto Sear & Dowel Pin Pressing Machine is an advanced semi-automatic assembly system designed to assemble sear sub-components with high precision and repeatability. The machine handles the complex process of assembling bottom base, torsion spring, and P-cut dowel pin in a fully controlled environment. The major challenge of ensuring P-cut dowel pin orientation is addressed using a dedicated Poka-Yoke mechanism and P-cut dowel magazine, ensuring error-free assembly. Additionally, the system is designed with universal pressing capability to handle similar parts through quick-changeover fixtures.
Part Loading:
- Operator loads bottom base into fixture.
- Torsion spring is pre-positioned in the dedicated holder.
- P-cut dowel pin is supplied through a magazine with poka-yoke alignment.
P-cut Dowel Orientation:
- The poka-yoke mechanism ensures correct orientation of the P-cut dowel pin.
- Incorrect orientation is rejected automatically, avoiding assembly errors.
Assembly Pressing:
- Pressing head aligns over the part.
- Bottom base, torsion spring, and P-cut dowel are assembled in sequence.
- Pressing force & stroke are monitored in real time.
Cycle Completion:
- Assembled part is released from the fixture.
- HMI displays assembly OK / NOK status.
Changeover Capability:
- By replacing fixture plates and updating HMI settings, similar assemblies can be processed.
Key Benefits:
- Automated & error-proof assembly of complex sear components.
- P-cut poka-yoke system ensures 100% correct dowel orientation.
- Multi-component assembly with force & position control for quality assurance.
- Quick-changeover design enables universal application for similar parts.
- Operator safety ensured with guarded enclosure and dual push buttons.
