机型: ABB IRB 120两台客户: 上海XX汽车零部件有限公司问题报告:客户对产品精度的要求非常高,他们对于标准和规范的机器人精度测试也有很高的需求。然而,目前来说,ABB机器人产品的精度以及后期调整服务还未能满足现场要求,仍未解决问题。 这种情况可能对客户的业务产生不利影响,因为精度是机器人在执行任务时非常重要的一个指标。如果机器人的精度无法达到客户的高标准,可能会导致产品质量下降、工作效率低下以及成本增加。此外,由于每年需要进行规范的精度测试,如果ABB机器人产品无法符合要求,将会给客户带来额外的压力和麻烦。 问题解析:当时接到这个Case,我的第一反应就是 测试方法可能不对。因为规格书上写的其实是 示教点 (Tech Point)的精度。而客户在测的是理论点和实际点 (Actual point vs Theoretical point)的偏差,这更偏向于 Positioning Accuracy,或者说, **精度 (Absolute Accuracy)(可参考专栏内关于**精度的说明)。机械臂应该没有问题。只需要让客户修改测试方法就可以了。 那么,给客户推荐什么解决方案??结合客户的需求和疑惑,我司专业的技术人员带上鲸络智能自研开发的精度测试仪器上门为客户做精度的测试和判定,在专业的测试过程中也发现有以下几点原因1.因为客户没有专业的调试工程师,机器人操作不专业导致。2.不利于高精度工作的机器人姿态设定:机器人工作时所设定的姿态也可能对其在高精度要求下的工作产生不利影响。我们的技术人员将会针对客户的需求,进行机器人姿态的调整和优化,以确保机器人能够在*佳状态下进行高精度的工作。3.工具长度和固定性:客户使用的工具长度过长且固定性不完全,这可能导致精度偏差的放大。我们会与客户合作,共同寻找解决方案,例如缩短工具长度或改进固定方式,以减少不确定性并提高精度。我们理解客户对产品精度的高要求和标准,并承诺在测试中发现的问题上提供解决方案。通过为客户提供专业的调试和优化服务,我们致力于改善产品精度,以满足客户每年规范测试的需求。我们的目标是确保机器人产品在符合客户的高标准下实现卓越的精度,并确保客户对产品的质量和性能感到满意。 非常感谢客户对我们公司的信任和支持。我们坚持以客户需求为导向,通过我们的专业团队的努力和不断改进,我们将为客户提供*优的解决方案,甚至超越客户的期望。 同时,我们还将继续致力于技术创新和产品升级,以适应市场的快速变化和客户需求的不断提升。我们承诺在技术领域不断加强自身实力,并与国内外相关领域的合作伙伴交流合作,共同推动行业发展。 如果您有任何关于机器人相关需求随时与我们联系。我们将竭诚为您提供满意的服务,实现您在机器人领域的愿景和目标。 再次感谢您对我们公司的支持与合作,期待未来能与您携手并进,共创美好的明天!

1. General maintenance1) Clean the manipulatorThe robot maintains and cleans the base and arm of the manipulator regularly;High pressure cleaning equipment can be used, but should avoid direct injection to the manipulator;If the manipulator is protected by grease film, remove as required.(Avoid using strong solvent such as acetone, avoid using plastic protection, in order to prevent the generation of static electricity, must use wet or wet cloth to wipe the non-conductive surface, such as spraying equipment, hoses, etc.Do not use dry cloth.2) Cleaning and maintenance of hollow wristsAccording to the actual situation, hollow wrists need to be cleaned frequently to avoid accumulation of dust and particles, and clean with a clean cloth that cannot afford pompous balls. After the wrist is cleaned, a small amount of Vaseline or similar substances can be added to the wrist surface, which will be more convenient for cleaning in the future.3) Regular inspectionCheck for oil leaks;Check whether the gear clearance is too large;Inspect cables between control cabinet, purge unit, process cabinet and manipulator for damage.4) Inspection of fixing boltsThe fastening bolts and fixing clamps that fix the manipulator on the foundation must be kept clean and shall not touch corrosive liquids such as water, acid and alkali solution.If corrosion resistant coating such as galvanized coating or coating is damaged, the relevant parts shall be cleaned and coated with corrosion resistant coating. 2. Axle brake testDuring operation, each shaft motor brake will wear normally.In order to determine whether the brake is working properly, it must be tested at this time.

1. Check the movement status of each axis cable, power cable and communication cable of the spraying robot.2. Check whether there is oil leakage or oil leakage in the gear box and wrist.3. Check the zero position of the spraying robot;Spraying robot each shaft motor and brake.4. Check lubricating oil on each axis of the spraying robot;Each shaft limit block;Disconnect all power supplies to the control cabinet.5. Check the main board, storage board, calculation board and driving board of the spraying robot;Spray robot control cabinet there is no sundries, dust and so on in the cabinet, check the tightness6. Check whether the joint of the control cabinet and manipulator is loose or whether the cable is loose or damaged;7. Check the storage battery of the program;Optimize the hard disk space of the robot control cabinet, ensure the normal operation space, etc., understand the safety guidelines in the safety Manual ‖, and shall not carry out any maintenance work on the spraying robot.The task must be undertaken by suitably trained skilled workers. The above are the basic seven aspects of the maintenance of spraying robot, in addition, we should also pay attention to the maintenance interval of spraying robot, various equipment maintenance interval depends on environmental conditions, operating hours and other factors and vary.Before spraying any operation, carefully study the operation manual of spraying robot, and then conduct operation after professional training.

Cable robots can be widely used, which is mainly due to cable performance attributes stand out, cable material is qualitative soft, superior tensile properties, flexible, and restore the performance is very strong, cable bend in a short time in a recovery state, without causing cable partial necrosis, late will not affect the cable to use.The needs of the development in all walks of life speeds up the cable robot, the various types of cable markets robot type cable, it would be good for consumers and also have its downside, benefit is selectively widely, can choose appropriate own needs cable, on the other hand is a cable type many, the product type in general will be miscellaneous, for users to choose the appropriate cable will be a big challengeExplicit use of functionsFor any consumer, when buying a cable, it's important to know exactly what's worth buying.What are the practical applications of cables?On the basis of these, make clear the purchase requirements, and understand the parameters and functions of all aspects of the cable in detail through the cable specification. The general robot cable has the following advantages:(1)wear resistance, the use of efficient composite material to enhance the cable in the process of use of friction resistance(2)Compressive resistance, which can be seen from the recovery performance of the cable(3)Good tensile force effect

While everyone knows the importance of robot maintenance, it is still unclear how often to maintain a robot.Now let me make it clear that for every year or 6,000 working hours that a robot works, it has to do maintenance work.The maintenance contents of the robot mainly include the replacement of lubricating oil of six shaft reducer and lubricating oil of J4 shaft gear shaft, the replacement of wearing parts, the inspection of operation condition of each module in the control cabinet, and the inspection of wear condition of each cable in the control cabinet.If grease is not replaced for a long time, the six axes of the robot will be blocked by deteriorated grease, which will not lubricate the reducer but increase wear and shorten the service life of the robot.When changing the grease, we can obviously see that the grease inside has become cloudy with pungent smell. Therefore, timely changing the grease is a must for robot maintenance.Some vulnerable parts in the control cabinet will not be replaced for a long time, and the aging of vulnerable parts will cause the robot to stop.Check the running condition of each module in the control cabinet regularly and check each cable carefully, etc., which can greatly reduce the downtime of the robot.Therefore, regular maintenance of robots is very necessary. Meanwhile, both robot maintenance and robot maintenance need professional engineers to operate. Otherwise, once operation error occurs, it is very likely to cause more damage.

At ordinary times, we must do a good job in the maintenance of industrial robots, because it may affect the working efficiency of robots at ordinary times.So how do you do robot maintenance?Generally speaking, when you buy a robot, there will be instructions on how to use it and how to maintain the industrial robot.The maintenance method of different brands is also different naturally.When carrying out the maintenance of industrial robots, one should carefully read the maintenance operation manual. The operation manual indicates how often to maintain which parts, what are the items of daily maintenance, three-day maintenance, weekly maintenance, monthly maintenance, annual maintenance and every three years maintenance.Robot maintenance is a delicate technical work, many projects need professional tools and experience, such as robot oil change, replacement of wastage spare parts, etc., all need professional maintenance personnel to better operate, so as to avoid operation errors and cause unnecessary damage to the robot body.Regular maintenance of the robot can greatly reduce the failure rate of the robot. In the process of maintenance, engineers will also carefully check whether there is wear and tear in all parts of the robot, and timely remind the customer, greatly reducing the robot's downtime.Robots are just like people. People need to keep in good health, and industrial robots also need regular maintenance. Only after the maintenance can industrial robots run more healthily.
