What is the Difference Between Electric Feeder and Pneumatic Feeder

Electric feeders utilize a motor to drive the feeding mechanism to move components from a magazine or reel to a pick and place head. This type of feeder is easily programmable and can handle a wide range of component sizes and shapes, making it a versatile choice for SMT assembly. Additionally, electric feeders tend to place components more accurately and consistently than other types of feeders.

Pneumatic feeders, on the other hand, use compressed air to move components from a magazine or reel to a pick and place head. This type of feeder is known for its high-speed capabilities and can easily handle larger components. Pneumatic feeders are also simpler and less expensive to maintain than electric feeders.

How to Install a Pneumatic Feeder

Determining installation location: Assess specific stamping needs to pinpoint the ideal location for the pneumatic feeder. Depending on the application, the feeder can be set up to either feed or pull materials.

Setting up the mounting Plate: Place the mounting plate beside the intended stamping press location, mark screw hole positions, and secure the plate with screws after drilling the necessary holes.

Aligning the main body: Place the main body of the pneumatic feeder in alignment with the mounting plate’s position.

Installing the actuating rod: Set up the actuating rod mechanism on the press table, ensuring it lines up with the floating rod on the pneumatic feeder’s main body.

Three-piece unit and final touches: Affix the three-piece combination unit beneath the body of the stamping press. Connect it to an external air source and link it to the pneumatic feeder’s main body via the high-pressure tube. Finish off the installation by injecting lubricating oil into the unit.

Operational Sequence Of The Pneumatic Feeder

Compressed gas entry: Compressed gas enters the feeder, initiating the internal pneumatic circuit.

Clamp release and material securing: The directional valve is raised, releasing the fixed clamps.Simultaneously, the movable clamps extend into material gaps, securing the material in place.

Material advancement: The feeding cylinder advances, propelling the material forward.

Reverse signal from stamping press: As the stamping press descends to a specific distance, it sends a reverse signal to the directional valve.

Clamp engagement and preparation for next cycle: The fixed clamps now clamp the material securely.Movable clamps retreat from material gaps.The feeding cylinder moves back, preparing for the subsequent feeding cycle.

Collaborative motion in stamping process: The stamping press and pneumatic feeder work in tandem.Stamping press executes "upward-descent-upward" actions, while the pneumatic feeder performs "feeding-retracting-feeding" motions.

Exhaust hole and threaded connector: Positioned on the base’s inner side, facilitating air release.

Elbow and sliding switch: Enables smooth air flow control within the feeder.

Quick connector: Links components swiftly for efficient operation.

Fixing clamp and base: Ensures secure attachment to the press, enhancing stability.

Guide rail and movable Clamp Plate: Guides and secures movement for precise feeding.

Material stop wheel: Regulates material flow, enhancing control.

Feeding length adjustment screw and feed drum: Fine-tunes feeding parameters for optimized performance.

Solution to The Deviation of Materials in Pneumatic Feeder

The mold is not properly installed in place, causing the material to run off when feeding. When installing a small mold on a large punching machine, the mold installation is often not in place. At this time, the center line of the mold is not on the same line as the center line of the feeder, and the deviation is inevitable. At this time, the mold mounting position is re-adjusted. Can be solved.

The position of the pneumatic feeder's retaining wheel is not properly adjusted, which causes the material to be deflected during feeding. Re-adjusting the position and width of the retaining wheel can be solved.

When the material is not squared during the feeding, the material is deflected into the feeder, and the material is retracted after retracting.

The wear of the O-ring seal causes the air leakage of the exhaust hole to cause the pneumatic feeder to not work normally. At this time, the O-ring can be replaced to solve the problem.

The looseness of the pneumatic feeder is incorrect, which causes the material to deflect and re-adjust the relaxation time of the R-type solenoid valve of the pneumatic feeder.

Maintenance Tips for Pneumatic Feeder

Regular inspection

Conduct routine inspections of the pneumatic feeder to check for any signs of wear and tear, loose components, or potential issues. Pay particular attention to the air hoses, seals, and fittings to ensure there are no leaks or damage that could affect performance.
