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.

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.

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.

±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.
