简体中文 One.Electronics Manufacturing: "Flexible Movers" of Precision Components
Scenario pain pointsMobile phone motherboards, chips and other precision components with large size differences (such as 5 × 5mm to 50 × 50mm), the traditional conveyor line to replace the fixture downtime of 2 hours / time, the loss of daily production capacity of more than 15%.
prescription::
- Dynamic Ranging TechnologyAdopting double-slide synchronous belt structure (such as the patented design of Ningbo Zhenyu), the servo motor achieves stepless adjustment of 5-200mm pitch, and the switching time is <3 minutes.
- Zero Damage Transmission: Rubber-coated rollers (Shore hardness A85±3) combined with anti-static treatment to avoid scratches on precision components.
Case effectAfter the introduction of a Shenzhen electronics factory, the efficiency of product changeover increased by 90%, and the yield increased from 92% to 98.5%.
Two.Automotive components: "Intelligent dispatcher" for heavy-duty tooling
Scenario pain pointsEngine cylinder block (single weight 80-150kg) is piled up at the welding station, which is easy to collide with manual handling, and the average monthly equipment maintenance cost is over 120,000 RMB.
prescription::
- Accumulated drum design: Sichuan Hodin's patented technology realises on-line dynamic shunting of heavy-duty rollers (wall thickness ≥3mm), with a pitch adjustment accuracy of ±1mm.
- impact resistant construction: Stainless steel cylinder + double sprocket drive (pitch 12.7mm), load ≥ 300kg/roll.
Case effectAfter the transformation of the welding line of an automobile company, the collision rate of the workpiece went to zero, and the production capacity was increased by 22%.
Three.Food packaging: "Efficient sorter" for multi-size boxes
Scenario pain points: E-commerce warehouses need to handle 20-60cm boxes at the same time, manually adjusting the spacing of the production line to congestion, the efficiency of the peak period decreased by 40%.
prescription::
- AI vision linkage control: The sensor recognises the box size in real time and matches the spacing automatically (e.g. 60cm box → roller spacing ≤ 20cm).
- Sanitary Configuration: Food-grade PU rubber sleeve (FDA compliant), supports high-pressure water gun cleaning.
Case effect: The sorting efficiency of a fresh food warehouse reached 6,000 boxes/hour, and the package breakage rate was reduced to 0.3%.
3 Golden Rules of Selection
| dimension (math.) | Key indicators | Guide to avoiding the pit |
|---|---|---|
| Material Adaptation | Length and width tolerance ±5mm/weight fluctuation ±10% | Flexible Packaging Selection PVC Sleeve Roller |
| System Matching | Power roller spacing = 1/4 cargo length (formula P ≤ L/4) | Double chain drive needs to satisfy T = n x p/2 (n is an integer) |
| Environmental Compliance | Humidity＞80% Selection of hard chrome plated roller | Zinc/copper not permitted in food lines |
💡Industry TrendsIn 2024, the patents of head enterprises will focus on "non-stop pitch adjustment" (e.g., Sichuan Haoding) and "AI self-learning pitch optimisation" (Ningbo Chenyu), and priority will be given to the integration of these two technologies when selecting a model.
