asm siplace smart feeder without sensor 4mm 00141478

ASM SMT machine 4mm feeder without sensor (model: 00141478) is an economical and practical mechanical feeding device, designed for 4mm wide tape, suitable for mounting standard SMD components such as resistors, capacitors, small diodes, etc. The feeder adopts a purely mechanical transmission structure without electronic sensors. It has the characteristics of simple structure, easy maintenance and low cost. It is a basic but key feeding equipment in the SMT production line.

2. Working principle

Power input:

The SMT machine provides power through a mechanical cam or pneumatic drive (depending on the model) to push the feeding ratchet inside the feeder.

Tape advancement:

Each time the ratchet moves, it drives the tape forward 4mm (standard spacing) so that the next component reaches the suction position.

Cover film peeling (optional function):

Some models are equipped with a simple peeling mechanism, which slightly lifts the cover film when feeding, making it easier for the nozzle to pick up the component.

Manual reset:

When changing materials, the reset lever needs to be manually pulled to return the tape to the initial position.

Note: Since there is no sensor, the feeder relies on the mechanical position detection function of the placement machine to determine whether the feeding is in place.

III. Product advantages

High cost-effectiveness:

No electronic components, the price is 30%~50% lower than that of the feeder with sensor, suitable for production lines with limited budget.

Simple and reliable structure:

Pure mechanical design, extremely low failure rate, especially suitable for high dust environment.

Convenient maintenance:

No need to calibrate the sensor, only daily cleaning and lubrication are required.

Strong compatibility:

Adapt to various placement machines such as ASM SIPLACE S/X/D series (need to confirm the specific model interface).

Long life:

Key components are made of hardened steel, with excellent wear resistance and a lifespan of more than 8 million times.

IV. Technical features

1. Mechanical structure

Compact design: size 100mm×35mm×25mm, suitable for high-density feeder station layout.

Single ratchet feeding mechanism: the step distance is fixed to 4mm (not adjustable).

Spring pressing system: automatically adapts to the tape thickness (0.1~0.5mm).

Manual unlocking device: press the release lever to easily remove the tape when changing materials.

2. Adaptability

Tape type: only supports 4mm wide tape (pitch 4mm).

Component height: suitable for components with a height of ≤3mm (such as 0402, 0603 packages).

Drive mode:

Mechanical drive type (cam linkage, such as SIPLACE S series).

Pneumatic drive type (external air pressure is required, such as some old models).

V. Core functions

Basic feeding:

Stable push of 4mm pitch tape to ensure continuous supply of components.

Simple anti-stuck material:

Prevent the tape from excessively advancing or retreating through a mechanical limit structure.

Fast material change:

Manual unlocking design, material change time ≤5 seconds.

Compatible with standard trays:

Support 7-inch and 13-inch roll trays.

6. Role in SMT production line

Economical feeding solution:

Provide cost-effective options for cost-sensitive production links (such as consumer electronics).

Stability and reliability:

The mechanical structure has no aging problems of electronic components and is suitable for long-term continuous operation.

First choice for spare feeder:

Often used as a backup solution for feeders with sensors to cope with sudden needs.

VII. Common faults and solutions

Fault phenomenon Possible cause Solution

The material belt cannot be advanced 1. Ratchet wear

2. The material belt is stuck

3. The drive mechanism fails 1. Replace the ratchet (P/N: 00141479)

2. Clean the material belt path

3. Check the SMT drive cam

Inaccurate feeding step 1. Ratchet spring fatigue

2. Uneven material belt tension 1. Replace the reset spring

2. Adjust the tension of the tray

The material belt frequently jumps out of the guide rail 1. The pressure piece is deformed

2. The guide rail screw is loose 1. Correct or replace the pressure piece

2. Tighten the guide rail fixing screw

Abnormal sound 1. Gear lacks oil

2. Bearing wear 1. Add grease

2. Replace the bearing (Φ3mm)

Unable to reset manually The reset rod is stuck or the spring is broken Disassemble, clean or replace the reset component

VIII. Maintenance guide

1. Daily maintenance

Cleaning:

Blow away the debris inside the feeder with an air gun every day (air pressure ≤ 0.2MPa).

Clean the contact surface of the guide rail with an alcohol swab every week.

Lubrication:

Apply white lithium-based grease to the ratchet shaft and guide rail every month.

2. Regular maintenance (every 6 months)

Full disassembly: Check the wear of the ratchet, spring, and bearing.

Replace wearing parts:

Ratchet (life of about 5 million times)

Pressure spring (life of about 3 million times)

Mechanical accuracy verification:

Use a standard 4mm tape to test the feeding step, and the error should be ≤±0.1mm.

IX. Selection and use suggestions

Applicable scenarios:

Mass production of standard components (such as resistors and capacitors).

Occasions that are cost-sensitive and do not require extremely strict mounting accuracy.

Unsuitable scenarios:

Precision mounting that requires detection of material shortage or tape status (it is recommended to use a model with a sensor).

Special-shaped components with a pitch other than 4mm.

Spare parts recommendation:

Ratchet kit (P/N: 00141479)

Reset spring (P/N: 00141480)

10. Summary

ASM 4mm feeder without sensor (00141478) has become a classic choice for SMT basic feeding with its minimalist design and super cost-effectiveness. Although the function is relatively simple, its reliability and low maintenance requirements make it irreplaceable in specific applications. Users need to pay attention to its complete reliance on mechanical drive and ensure that the feeding signal of the placement machine matches it. For high-mix production environments, it is recommended to use a small number of feeders with sensors as a supplement to key stations.
