460 High Efficiency PCB Cooling Buffer Stocker With 0.5M Link Conveyor

HDY-460 high-efficiency cooling buffer stocker with integrated 0.5M link conveyor is a specialized buffering equipment designed for gap transition between SMT automated machines. It solves production line waiting & blocking issues by temporary PCB storage with cooling circulation, realizing First-In First-Out (FIFO) material management.

The machine adopts sturdy custom sheet metal frame and multi-layer aluminum circulation trays with 4MM flat belt conveying system, fixed 50mm layer pitch. Equipped with Inovance servo motor paired with precision ball screw to drive magazine step lifting, together with independent stepping transport motor for stable board transfer. Four Panasonic photoelectric sensors are installed all around to detect PCB position and effectively avoid board jamming damage.

It supports maximum 20 pieces PCB mixed storage of NG defective boards and OK qualified boards, compatible with large PCB up to 500*460mm. Stepper motor automatic width adjustment fits various board widths from 50–460mm. Controlled by reliable Panasonic PLC and Xiankong true-color touch screen, it reserves MES communication interface for smart factory data linkage, with built-in cooling fans to rapidly dissipate heat from hot PCBs after reflow. Standard transfer height 920±30mm and left-to-right conveying direction match universal SMT production line standards. The whole control unit uses Mean Well power supply and Omron relays for stable long-time continuous operation, with automatic fault alarm function for easy troubleshooting.

1. Dual Function: PCB Cooling + Production Line Buffering
   Ordinary buffer machines only provide temporary storage without heat dissipation design. Our HDY-460 comes with built-in multi cooling fans, quickly lower high temperature of PCBs out of reflow oven to avoid component deformation, greatly improving post-process inspection yield.

2. Large Size PCB Compatibility & Mixed NG/OK Storage Design
   Most market buffer stockers only support small PCBs below 400mm width. This model handles max 500*460mm large circuit boards and allows mixed storage of good and defective boards without separate equipment, saving workshop space and equipment investment cost.

3. 4 Panasonic Anti-Jam Sensors + Precision Servo Ball Screw Lifting
   Cheap buffer machines only install 1–2 simple sensors, easily cause jamming and scratch boards. Four brand Panasonic sensors monitor the whole transmission channel in real time; servo + ball screw lifting brings ultra-smooth step movement, no shaking or board offset during storage and discharge.

4. FIFO First-In First-Out Intelligent Management
   Adopts standard FIFO storage logic, prevents long-time stacking of PCBs and oxidation. Conventional simple buffer machines store and release boards randomly, leading to mixing of production batches and difficult traceability.

5. MES Connection & Automatic Width Adjustment for Smart Factory
   Equipped with Panasonic PLC and automatic stepper width adjustment, supports docking with factory MES system to upload production data. Ordinary low-cost buffer stockers use fixed width without data communication function, unable to meet digital workshop demands.

6. Full Brand Electrical Components, Ultra-Low Failure Rate
   Core electric parts all adopt famous brands: Panasonic PLC & sensors, Inovance servo, Mean Well power, Omron relay. Compared with generic no-brand accessories used by peer cheap machines, our unit runs stably for long-term mass production, cutting maintenance downtime greatly.

7. 0.5M Integrated Link Conveyor, Plug-and-Play Installation
   Built-in 0.5M PCB link conveyor as one unit, no extra separate conveyor needed for line connection, simplify layout and reduce extra purchasing cost. Separate buffer machines require matching additional transfer conveyors for docking.

8. 20 PCS Large Capacity Storage To Eliminate Line Blockage
   Max 20 boards temporary storage capacity effectively balance production beat difference between front and back SMT machines, avoid frequent line pause caused by fast/slow equipment speed mismatch and raise overall line output.

HDY-460 cooling buffer stocker is widely installed between SMT production equipment including reflow oven, AOI optical inspection machine, SPI solder paste detector, chip mounter and selective soldering machine. It works as a temporary buffer station to balance inconsistent production speed of upstream and downstream machines.

It fits manufacturing of large consumer electronics PCBs, automotive circuit boards, new energy control boards, industrial mainboards, TV & monitor display boards, communication equipment circuit boards. Suitable for medium & large electronic assembly factories, intelligent unmanned SMT workshops, OEM automated production lines and digital manufacturing plants, realizing continuous, stable and traceable PCB assembly workflow.
