防撞条要快回弹，撞完立刻弹回接着扫。 慢回弹吸能但复位慢，机器人场景要的是快回弹。
脱胶不全是料的事，粘合界面在长期震动下疲劳。 除了剥离强度，粘合剂选型、表面处理、固化时间一起看。
瓷砖、木地板、地毯，磨损程度差很多。 按目标市场主流地面测，别拿单一地面数据套所有家庭。
防撞条用一阵刮花磨平，变丑又不回弹。 表面硬度低易刮花，长期受压易变形，耐磨加密度一起提。
磨耗差三成，实际可能差一倍。 实验室固定摩擦和随机碰撞不同，按真实撞击角度验收才准。

Bumping into walls and furniture every day, the anti-collision strips wear out and peel off. The anti-collision strips on the robot vacuum can't withstand collisions, turning the robot into a bumper car.
Conclusion first: bumper strips, wear-resistant rebound tied together
The collision strips on a robotic vacuum are 'things that get hit every day': hitting walls, hitting furniture, grinding on the floor.
Materials need to be wear-resistant, resilient, and not delaminate — conclusion first: for the bumper strips of sweeping robots, SEBS-based TPE is mainstream; if wear resistance is a high requirement, TPU is preferred.
The biggest drawback of the anti-collision strips on robot vacuum cleaners: wear is 30% worse, and you can tell by looking at the soles of your shoes. A 30% difference in wear data feels twice as bad in actual use — wear is the touchstone of durability.
The collision-proof strip on a robot vacuum is a functional part: wear-through or peeling are both problems. Choosing the right material makes the robot more reliable—it's a functional part, don't skimp on material costs.
Why does TPE collide every day: wear resistance can be added, rebound can be adjusted
Reasons for using TPE for the robot vacuum's anti-collision strip: wear resistance is achievable, rebound is achievable, efficiency is high, cost is controllable—together, these four make it suitable for the anti-collision strip.
Durability is key: collide every day, wear every day. Wear data should be verified according to actual use—once worn through, it's a problem.
Rebound cannot be skipped: after a collision, it must rebound. Compression rebound (according to standards) should be recorded in the inspection—without rebound, the collision protection is gone.
Hit it for a day: hit walls, hit furniture, the ground
Impact conditions: Colliding with walls and furniture. Rebound data must be checked—if there is no rebound, it's a problem.
Friction condition: ground friction. Wear data need to be verified—wear through, that's the problem.
Dust condition: dusty environment. Wear resistance data must be tested—abrasion, that's the issue.
TPE or TPU: Can you see through the bumper strip or not
| Dimension | TPE | TPU |
|---|
| Wear-resistant | middle | Strong |
| rebound | Can be done | Can do |
| Cost | Low | Medium-high |
| Overmolding | Mature | Mature |
| feel | soft and glutinous | Slightly hard |
| Batch | Stable | Stable |
Table reading: TPU is wear-resistant and strong but expensive; TPE is cheap and soft to the touch — mainstream bumper strips use TPE.
High-end models TPU, regular TPE — choose according to the model.
Wear Test Record Sheet: Weight Comparison After Friction
| Project | Method | Result |
|---|
| wear amount | Standard wear | mg |
| Resilience | Compression rebound | % |
| Impact Restoration | Physical impact | Restore |
| Surface condition | Visual | Unworn |
Table reading: All four data items must be complete for the anti-collision strip to pass—wear, rebound, and weather resistance cannot be omitted.
Data is recorded by batch, don't just look at individual samples.
Two pitfalls: wear falsification and rebound leak testing
Pitfall 1: Wear exaggeration. The report claims wear resistance, but it actually wears through — wear is accepted based on actual measurement.
Pitfall 2: Missing rebound measurement. If it doesn’t rebound after collision—compression and rebound must be measured.
Pitfall 3: Ignoring debonding. After long-term use, debonding — perform peel strength test and include it in acceptance.
Acceptance Three Questions: Wear Resistance, Resilience, Adhesion
Three questions: What method is used for wear, what standard is used for rebound, and what is the peel strength. One test: actual impact measurement — three questions and one test, the supplier's details are clear.
Wear testing should come first: a 30% difference in wear reveals the quality of the sole. Test the wear first, then discuss the price—wear is the touchstone of durability.
Making sample retention a habit: retain samples from each batch, and re-test wear and rebound by batch. When changing material for a batch, compare first before scaling up — stable batches lead to fewer customer complaints.
The anti-collision strip needs to rebound quickly, bouncing back immediately after being hit and continuing to sweep. Slow rebound absorbs energy but resets slowly; in robotic scenarios, what’s needed is a fast rebound.
Incomplete delamination is not entirely a material issue; the bonding interface fatigues under long-term vibration. In addition to peel strength, consider adhesive selection, surface treatment, and curing time together.
Tiles, wooden floors, and carpets wear very differently. Measure according to the mainstream floors of the target market; don't apply data from a single type of floor to all households.
The bumper strip gets scratched and worn flat over time, becoming ugly and not bouncing back. Its surface hardness is low and easy to scratch, it easily deforms under long-term pressure, so both wear resistance and density need to be improved.
A 30% difference in wear could actually be a difference of twice as much. Laboratory fixed friction and random collisions are different; acceptance based on the actual impact angle is the only accurate way.
Common Problems and Solutions Table for Robot Vacuum Bumper Strips
| Phenomenon | Reason | Countermeasure |
|---|
| wear through | Insufficient wear resistance | Change to a wear-resistant formula |
| Delamination | Adhesive fatigue | Change bonding process |
| Does not rebound | Insufficient rebound | Replace with fast-rebound material |
| Scratch | Low surface hardness | Surface hardening |
| Transformation | Long-term pressure | increase density |
The bumper strip is bumped every day, and its wear resistance is tested according to actual measurements. If the wear is 30% worse, it will show within half a year. Only a soft surface that doesn't leave marks when rubbed against furniture is considered qualified.
The bumper strip needs to rebound quickly, resetting immediately after impact without jamming the wheels. Materials with low hardness are more resilient, while if compressed over 30%, they will collapse after a few impacts.
The hardness of the strip should be matched; too hard will damage the furniture, while too soft will provide no support. Around Shore A 60; test by striking on actual furniture samples, and keep batch samples for re-testing each season.
The anti-collision strip wears about 30% faster and shows wear in half a year; the soft surface can be rubbed on furniture without leaving marks. After a collision, it quickly rebounds and resets without jamming the wheels, with low deformation and good memory.
Cologne Customer Case: Insufficient Oil Resistance Causes Oil Swelling, Adjusted Parameters for Over a Thousand Hours
A shoe material factory in Yantai found that the collision strips of their floor-cleaning robots lacked oil resistance and would swell and deform after soaking in oil. Kolon helped adjust the injection molding parameters (mold temperature/material temperature/holding pressure), and the 1000-hour aging test was passed in one go. Once the parameter window was right, the oil resistance data stabilized—both the process and the formulation need to be correct.
Summary
When selecting anti-collision strips for a robot vacuum, first test the wear, then check the rebound. If the wear differs by 30%, in actual use it will feel twice as different.
