数据按批次记，别只看样品。
两个坑：磨耗造假、回弹漏测
坑一：磨耗虚标。报告写耐磨，实际磨穿——磨耗按实测验收。
坑二：回弹漏测。撞完不回弹——压缩回弹，必测。
坑三：脱胶忽略。用久脱胶——剥离强度测试，写进验收。
验收三问：耐磨、回弹、粘接力
三问：磨耗按什么方法、回弹按什么标准、剥离强度多少。一验：实际撞击实测——三问一验，供应商底细清楚。
磨耗验证要先行：磨耗差三成，鞋底见分晓。先测磨耗，再谈价格——磨耗，是耐磨的试金石。
留样要成习惯：每批留样，磨耗回弹按批次复测。批次换料先对比再放量——批次稳，客诉少。
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, and rubbing against the floor.
Materials need to be wear-resistant, resilient, and not delaminate — conclusion first: for bumpers on robot vacuum cleaners, 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 your shoe soles reveal the truth. When wear data is 30% worse, actual usage feels twice as bad — wear is the touchstone of durability.
The collision strips on a sweeping robot are functional parts: wear-through and adhesive peeling are problems. Choosing the right material makes the robot more stable — functional parts, don’t skimp on material costs.
Why does TPE collide every day: wear resistance can be increased, rebound can be adjusted
Reasons for using TPE in robot vacuum collision strips: wear-resistant and feasible, resilient and feasible, high efficiency, controllable cost—these four reasons together make it suitable for collision strips.
Durability is key: bumped and worn every day. Wear data is verified according to actual use—if it wears through, then 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: hitting walls and furniture. Rebound data must be checked—if there is no rebound, it is 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 do | Can be done |
| Cost | Low | Medium-high |
| Encapsulation | Mature | Mature |
| hand 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 |
| Rebound rate | 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 should be accepted based on actual measurements.
Pitfall 2: Missing rebound measurement. If it doesn't rebound after impact — compression 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 wear first, then talk about 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 mean 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 adhesive 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.
Bumper strips can get scratched and flattened over time, becoming ugly and not bouncing back. The surface hardness is low and easy to scratch, and long-term pressure can cause deformation. Wear resistance and density should be improved together.
A 30% difference in wear could actually be a difference of twice as much. Laboratory fixed friction and random collisions are different; acceptance is only accurate when tested according to the real impact angle.
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 retain their shape well, while if the hardness exceeds 30%, it will collapse after a few impacts.
The hardness and softness of the bumper strip must be matched; too hard will damage furniture, too soft provides no support. Shore A 60 ±, test by hitting actual furniture pieces, retain samples by batch for seasonal retesting.
The wear difference in bumper strips is about 30%, visible within half a year. Soft surfaces wipe furniture without leaving marks. They rebound quickly after impact, do not jam the wheels, and maintain low compression and good memory.
Cologne Customer Case: Insufficient Oil Resistance Causes Swelling When Soaked, Adjusting Parameters Lasts Over 1000 Hours
A shoe material factory in Yantai had broom robot bumper strips with insufficient oil resistance, swelling and deforming after oil immersion. Cologne assisted in adjusting injection molding parameters (mold temperature / material temperature / holding pressure), passing a 1000h aging test in one go. When the parameter window was correct, oil resistance data became stable—both the process and the formulation must be right.
Summary
For choosing bumper strips for sweeping robots, first measure wear, then check rebound. If wear differs by 30%, in actual use it may differ by 100%.
“What material should this part use?”
This is the question we are asked most often and the one we most like to answer. Because the answer is never 'choose the most expensive,' but 'choose the most suitable.'
Ningbo Cologne New Materials Co., Ltd. produces modified thermoplastic elastomers, modified nylons (PA6 / PA66 / PA46 / PA11 / PA12 / PA6T / PA9T and nylon alloys), modified PPO / PPS, and also supplies major chemical giants with nylon resin, secondary grade materials, and bulk materials in stock.
