Automatic FOB Bonder OL-PB3000
Equipment Overview
The OL-PB3000 Automatic FOB Bonder, manufactured by Shenzhen Olian Automatic Equipment Co., Ltd., is a cutting-edge device designed for the automatic PCB loading, ACF (Anisotropic Conductive Film) attachment, alignment, and thermal compression between FOG (Flexible On Glass) products and PCB (Printed Circuit Board) in LCD products ranging from 5.5″ to 17.3″. This equipment is compatible with single-edge multi-segment FPC (Flexible Printed Circuit) products and can be integrated with other machines from the same company to form a production line.
Device Structure and Workflow
The device consists of several key components, including PCB loading, FOG loading, pre-main pressing platform, detection platform, and an outfeeding system. Its workflow starts with PCB loading, followed by FOG loading. Then, the PCB undergoes plasma cleaning. Subsequently, the FOG is transferred to the pre-main pressing platform, and the PCB is also moved to this platform. After alignment between FOG and PCB, the main pressing process takes place. Post pressing, the product undergoes various detection processes. If any deviation is detected, the product is discharged through a belt. If the product passes the detection, it is handed over to the subsequent machine or outfed.
Applicable Product Specifications
The OL-PB3000 accommodates LCD dimensions from 100mm×100mm to 380mm×380mm. The FPC & COF (Chip On Film) dimensions range from 20mm×20mm to 80mm×80mm, with a maximum of 6 FPC & COF units on a single edge and a center distance of≥60mm. The PCB length can be 70 – 380mm, width 10 – 60mm, with a maximum of 1 PCB. The maximum finished product size is 480mm. The ACF can be of the reel type, with 2 or 3 layers. The ACF attachment length is 5 – 80mm, and the width is 0.3 – 5mm, adjustable for different widths. The ACF reel has an inner diameter of 18mm or 25mm, and the maximum reel diameter is 200mm.
Machine Performance Indicators
The OL-PB3000 boasts high-precision production capabilities. The ACF attachment accuracy is X:±0.15mm, Y:±0.1mm. The FOB main pressing accuracy is X: ±25um, Y:±30um. The production cycle is≤10sec/pcs, with the ACF setting time≤0.5sec and the main pressing setting time≤10sec. It is suitable for FOB bonding of single-edge 1 – 6 FPC products. When switching to a new model, the time required is≤90min, and for existing models, it’s≤50min, depending on the engineer’s proficiency.
Process Parameter Specifications
The temperature control for ACF-bonding ranges from RT (Room Temperature) to 120℃, and for main-bonding, it’s RT to 400℃. The heating method for the pressing head is constant heat, with temperature control via PID (Proportional Integral Derivative) control and touch screen settings. The temperature error on the pressing head surface is±5℃, using K-type thermocouples. The time setting for ACF-bonding is 0.1 – 9.9Sec, and for main-bonding, it’s 0.1 – 99.9Sec. The pressure regulation range for ACF-bonding is 10 – 150N, and for main-bonding, it’s 20 – 600N. Pressure regulation for ACF is via a precision pressure regulator, while for main pressing, it’s controlled by a proportional valve and touch screen adjustments.
