This Terminal Stitching Machine is designed for the specific task of cropping and inserting terminal pins into the core of connectors. The machine is initially loaded with spools of different terminal pins and then they are individually cropped and inserted into the core. Operators loads the spool, while the machine automates the cropping and insertion process using hydro pneumatic tool and robotic arm, balancing efficiency as well as human control. The Terminal Stitching Machine is capable of handling seven spools for the insertion of up to seven different type of terminals.
Key Features:
- Hydro pneumatic tool for terminal cropping.
- SCARA robot for precise insertion of terminals.
- Fully customizable according to requirement.
- Easy accessibility in case of maintenance activities.
- HMI for easy communication between operator and machine.
Specifications:
- Input Power: 19kW
- No: of cells: 4
- Operating Pressure : 6 bar
- Robo : 4 axis SCARA
- Cropping Tools: 7 Nos.
Frequently Asked Questions
What is a terminal stitching SPM used for in ECU connector manufacturing?
A terminal stitching SPM is used to automatically insert and secure metal terminals into plastic ECU connector housings. It ensures consistent insertion depth, correct orientation, and reliable electrical contact while reducing manual errors and improving production consistency.
Can the machine handle terminals supplied in reel form?
Yes. The machine is designed with a terminal cropping and feeding mechanism that processes terminals directly from reels. This ensures continuous operation, reduces handling time, and improves cycle consistency.
Is automated insertion possible for different ECU connector variants?
Yes. The SPM can be designed to handle multiple connector variants (typically 2–3 part numbers) using quick-change tooling, programmable recipes, and modular fixtures to minimize changeover time.
Can dummy pins be inserted automatically?
Yes. Dummy pin insertion can be integrated into the same machine cycle or as a secondary station, depending on connector design and production requirements.
How is correct terminal insertion verified?
Insertion quality can be verified using a combination of:
- Presence detection sensors
- Terminal height verification
- Optional pull-force monitoring to ensure proper retention
These checks help prevent downstream failures and rework
Is vision inspection available for terminal stitching?
Yes, vision or optical inspection can be integrated to check terminal presence, orientation, height, and alignment. The feasibility depends on connector geometry and inspection tolerance requirements.
What cycle time can be achieved with a terminal stitching SPM?
Cycle time depends on the number of terminals per connector, inspection requirements, and automation level. Typical systems are designed to meet high-volume automotive production targets, such as multiple connectors per minute.
Can the machine support fast changeover between connector types?
Yes. The machine can be designed with quick-change nests, tool-less changeover components, and software-based parameter selection to reduce downtime during variant changes.
How compact is the machine footprint?
The SPM can be engineered with a compact floor-space design suitable for automotive production lines. Final footprint depends on the number of stations, inspection modules, and optional features.
Is the machine customizable based on ECU connector design?
Yes. Terminal stitching SPMs are typically custom-engineered to match specific connector dimensions, terminal types, quality standards, and production volumes.
