Product Highlights

Built for automated odd-form insertion.

S7900VI combines conveyor-based PCB handling, component feeding flexibility and a visible insertion work area, making it suitable for automating manual odd-form insertion tasks on through-hole or mixed-technology boards.

ODD

Odd-Form Insertion Focus

Designed for automated insertion of odd-form parts such as terminals, pins, eyelets, tact switches and similar through-hole components.

VIS

Vision-Assisted Process

Visual confirmation and sensing support the insertion process in the working area before or during component placement.

INL

Inline PCB Handling

PCB conveyors and work support structures allow the machine to fit naturally into production flow instead of working only as an isolated cell.

FLEX

Feeding Flexibility

The platform can be paired with feeder combinations selected according to component package style and the actual product mix.

Feeding & Components

Adapt feeding strategy to the component family.

Odd-form insertion projects are usually driven by the component mix. A practical proposal needs to start from the component type, lead shape, packaging style and board insertion positions.

Typical Feeding Approaches

Tray / custom presentationUseful when component orientation control is critical or the part is not suitable for high-density standard tape feeding.
Tape / tube / belt style feedingSelected according to the package style and the orientation requirements of the odd-form component.
Mixed feeder configurationsDifferent feeder types can be combined on one project when the PCB includes several component families.

Typical Odd-Form Components

Terminal & connector partsTerminal-type or connector-style odd-form parts used on power, signal or interface boards.
Pins, eyelets & mechanical THT partsInsertion tasks involving simple metal-form odd-form parts or mechanically rigid through-hole components.
Tact switches & special-form partsComponents that are difficult or inefficient to place manually in repetitive production.
Typical Applications

Reduce manual insertion load on THT and mixed-technology boards.

The most suitable projects are usually boards that combine repeated odd-form insertion positions with quality and throughput pressure that makes manual insertion costly or unstable.

Production Scenarios

Power boards & industrial controlsUseful where repeated terminals, pins or connector components create labor-intensive insertion steps.
Mixed SMT + THT assembliesSupports boards where odd-form components are inserted after upstream SMT or board handling processes.
Consumer or appliance control boardsSuitable when the product family includes stable odd-form insertion tasks across multiple board types.

Why Customers Ask for This Type of Machine

Labor reductionMove repeated insertion operations away from manual stations.
ConsistencyImprove insertion repeatability compared with purely manual handling.
Line integrationConnect insertion logic with conveyor-based PCB flow instead of building an isolated manual island.
Project Workflow

From component review to insertion solution.

A useful odd-form insertion proposal must be built around the component list and the board itself. The actual project normally starts from real parts, board drawings and target throughput.

Component Review

Check component families, package styles, lead forms and supply condition.

PCB Study

Confirm board dimensions, insertion positions, spacing and process sequence.

Feeder Definition

Select feeder concepts according to each odd-form part family.

Machine Proposal

Define machine configuration, workflow logic and line integration direction.

Customer Evaluation

Review sample boards, throughput expectations and solution scope.

Odd-Form Insertion Project Support

Send your components and PCB data.
We evaluate the insertion approach.

The fastest way to evaluate S7900VI is to send the PCB drawing, component list, packaging condition and the target output. Southern Machinery can then study feeding direction and solution fit.
