SMT automatic splicer: a comprehensive introduction to principles and advantages

I. Core Principle

The core principle of the SMT automatic splicer (Auto Splicer) is to achieve seamless splicing of new and old tapes through automation technology, ensuring that the SMT placement machine does not need to stop during the material change process, thereby ensuring production continuity. Its working principle mainly includes the following key links:

Tape detection and positioning

The remaining amount of the current tape is monitored in real time through a photoelectric sensor or a visual system, and the splicing process is triggered when the tape is about to run out.

Accurately identify the pitch (pitch) and width of the tape to ensure the alignment of the new and old tapes.

Tape splicing technology

Mechanical splicing: Use precision guides and clamps to fix the new and old tapes to ensure position alignment.

Bonding method:

Tape splicing: Use special splicing tape to bond the new and old tapes (applicable to most components).

Hot press splicing: Bond the tapes by heating and pressurizing (applicable to high temperature resistant materials).

Ultrasonic welding: Use high-frequency vibration to fuse the tapes (applicable to special materials).

Waste stripping: Automatically strip the protective film or waste of the material strip to avoid affecting the nozzle of the placement machine.

Mfumo wa udhibiti

Adopt PLC or industrial PC control, and cooperate with servo motor to achieve high-precision motion control.

Support communication with SMT placement machines (such as Fuji, Panasonic, Siemens and other brands) to achieve data synchronization.

Quality verification

Use sensors or visual inspection to detect whether the spliced material strips are aligned and firmly bonded to ensure that there is no deviation in subsequent placement.

2. Faida za msingi

SMT automatic material handling machines have significant advantages over traditional manual material replacement methods, which are mainly reflected in the following aspects:

Kuboresha ufanisi wa uzalishaji

Zero downtime material replacement: No need to stop the production line, 24-hour continuous production is achieved, and the overall equipment efficiency (OEE) is increased by 10%~30%.

Reducing material replacement time: Traditional manual material replacement takes 30 seconds to 2 minutes, and automatic material handling only takes 3~10 seconds, which greatly shortens the production cycle.

Reducing production costs

Reducing material waste: Accurately control the length of the material strip to avoid unnecessary losses during manual material replacement.

Save labor costs: reduce frequent operator intervention, especially suitable for night shifts or unmanned workshops.

Boresha usahihi wa uwekaji

±0.1mm high-precision splicing, avoid patch offset caused by material strip misalignment, and improve yield rate.

Suitable for stable feeding of micro components such as 0201, 0402 and precision ICs such as QFN and BGA.

Enhance production flexibility

Compatible with a variety of material strip specifications (8mm, 12mm, 16mm, etc.), supporting different component types.

Adaptable to mainstream SMT equipment (such as Fuji NXT, Panasonic CM, ASM SIPLACE, etc.).

Intelligence and traceability

Support MES/ERP system docking, record material receiving time, batch and other information, and realize production data traceability.

With abnormal alarm function (such as material strip breakage, splicing failure), reduce the risk of defective products.

III. Matukio ya kawaida ya maombi

Consumer electronics: large-scale PCB placement of mobile phones, tablets, etc.

Automotive electronics: production of automotive-grade components with high reliability requirements.

Medical/communication equipment: high stability requirements for precision components.

4. Future development trends

AI visual inspection: Combined with machine learning to optimize splicing quality judgment.

Internet of Things (IoT) integration: Remote monitoring of equipment status to achieve predictive maintenance.

More flexible design: Adapt to the needs of small batches and multiple varieties of fast line change.

Muhtasari
