简体中文 The LCD screen breaks a piece on the conveying line, and the heart of the whole workshop is dripping blood. But you know what? Now there are three kinds of "anti-vibration and anti-collision" transport solutions, can be transported to the LCD screen scrap rate of 0.5% below - how do they do? And suitable for which scenarios? Today we will break open and crumble, see how these devices in the vibration and collision to protect these "glass heart".
First, why is the LCD screen so afraid of vibration? Where in the end the traditional transport method does not work?
LCD modules are afraid of vibration, to what extent? An internal wire offset 0.1 mm, the entire screen may appear bad points. The problem with traditional conveyor belts lies in three places:
- painstaking: The conveyor belt itself is a hard material, and the screen is put in direct contact with it, hitting the bezel when it bumps;
- electrostatic steal: Friction between the belt and the screen generates static electricity, which accumulates to a certain voltage and directly breaks the circuit;
- out of alignment: The conveyor belt jerks and shifts the screen, and the robotic arm smashes the edges when gripping it.
A factory originally used ordinary roller line, monthly broken screen rate of up to 8%, and then changed the anti-vibration scheme directly pressed to 0.3% - the gap is so big.
Second, three kinds of anti-vibration and anti-collision conveying equipment, each with what "unique skills"?
1. Suspended aerial conveying line - "levitating" the screen
- Core anti-vibration design: Slide rail lifting + winch height adjustment, screen 2 metres off the ground to avoid ground vibration sources;
- buffer protection: EVA cushioning embedded in the carabiner to absorb lateral impact energy;
- Applicable Scenarios: Large-size car screens, curved screens (55" and above).
After a factory in Guangzhou used this system, the screen handling damage went to zero. However, it should be noted that the initial investment of this system is high, suitable for the annual production capacity of more than 500,000 pieces of large factories.
2. Intelligent Belt Modules - Fighting Vibration with "Flexible Contacts"
- shock absorptionSpring-loaded lever under the belt to cushion the shock when the spring contracts during vibration;
- non-slip and anti-bias: Convex wheel + elastic friction plate presses down on the edge of the screen to avoid sliding displacement;
- High precision positioning: Synchronous belt drive + servo motor, positioning accuracy up to ±0.1mm.
Jiangxi, a panel factory with a belt module, patch accuracy increased by 40%. However, the belt needs to be replaced every quarter, the maintenance cost is not low.
3. Integrated transport of shock-absorbing components - "shock-absorbing shoes" for the screen
- hydraulic cushioning: Cylinders are mounted at the bottom of the monitor and the impact energy is absorbed by the hydraulic fluid;
- limit switch: Spring deflection locks the limit lever to prevent excessive displacement;
- electrostatic protection: Surface coated with anti-static coating, friction voltage <50V.
Shenzhen Tianfu's innovative design reduces the transport breakage rate from the industry average of 5% to 0.8%. However, the cylinders need to be replenished with oil regularly, which is suitable for factories with professional maintenance teams.
What happens if you don't protect against earthquakes? Three common "rollover" sites
Scenario 1: Screen cracked during handling
The vibrations from the forklift trucks were transmitted to the conveyor line, and the stacked screens resonated and shattered - 37 screens were scrapped in a single batch at one plant as a result. After switching to a lifting line, the screens are transported in a single layer suspended in the air, completely avoiding ground vibration.
Scene 2: Robotic arm grabs crookedly and crashes the edges
The conveyor belt jitter caused the screen to shift by 3mm, and the robotic arm gripped and cracked it directly. After adding the convex wheel anti-slip device of the belt module, the screen position error is ≤0.3mm.
Scenario 3: Static breakdown of circuits in winter
Conveyed in a dry environment, the screen suddenly went black. Tests revealed a static breakdown. After using anti-static coated conveying equipment, no similar problem occurred again.
Fourth, don't step in the pits when choosing equipment! Three deadly practical details
1. Dimensional adaptation is more important than technical parameters
Don't just look at the anti-vibration data - a factory bought top-of-the-line lifting lines, only to have the winch not be high enough for the curved screen to fit in. Remember these three points:
- Slot depth of lifting clips > screen thickness 20%;
- The belt width is 5cm narrower than the screen for easy positioning;
- Allow 10mm margin for hydraulic stroke.
2. Environmental adaptation determines longevity
- EVA cushioning softens and fails at workshop temperatures >30°C - change to silicone;
- Humidity <40% environment must be equipped with static brush;
- Use belt modules with caution in dusty workshops (they need to be dusted every month).
3. Maintenance costs are the hidden expenses
- Lifting line cushions are replaced every 6 months (one piece costs $200);
- Belt modules are tensioned quarterly and belts are changed annually;
- The oil pressure system is checked monthly for sealing.
V. Future direction: the leap from "earthquake prevention" to "vibration resistance"
The current seismic solutions are passive damping, and the next generation is already developing active vibration resistance:
- Intelligent Damping Adjustment: Vibration is monitored with accelerometers and damping force is applied in reverse within 0.1 seconds;
- magnetic levitation transport (MLT): A test line in Suzhou lets the screen levitate 3mm, completely out of physical contact;
- Self-healing buffer layer: The material automatically repairs micro-cracks upon impact, increasing life expectancy by a factor of 3.
However, at this stage, using these three mature equipment, enough to press the broken screen rate within 1%. The key is to choose the right programme according to the size of your own products, workshop environment, budget - anti-vibration is not to buy the most expensive, is to buy the most right.
No matter how advanced the technology is, there is one truth: there is no one-size-fits-all anti-vibration solution, only continuous optimisation of anti-vibration thinking. From the selection of equipment to routine maintenance, a little less "almost", the screen is less broken a few pieces. After all, in the manufacturing industry, save the cost of scrap, are real profits.
