I'm going to find a reliable service provider for the phantom robotics service, look at three points: there's no original plant-level testing platform, whether engineers have been dry for more than five years and can be present within 24 hours. When i visited quinshan last week, they were replacing three fanuc r-2000ics with joint brakes, and the field engineers talked to me about some dry stuff, and they put together the criteria and industry common sense。
What kind of robot maintenance team is professional
Last month, i went to a car spare parts factory at the suzhou industrial park, where one of their fanuc m-900ia's arms was staggered for six months, because the last maintenance team did not perform load tests, replaced the brakes and went back in and ran for days without problems. Some hard indicators can be removed from this case:
In his workshop, kunsan han-sensei has a testing platform for the brands of fanuc, abb, kuka, andokawa and kawazaki. After the renovation, engineers go to the platform for a 24-hour aging test to simulate the load curve under the actual work situation, which has removed most of the secondary repairs。
What self-inspection should be done to avoid over-repair
At the end of last year, i went to a 3c electronics factory in changzhou, where two fanuc lr mate 200ids were also reported as srvo-021, and the production manager called the maintenance company, who said he was going to change the server amplifier and offered a high price. Then i showed it to the engineers, and the result was that the indirect electrical resistance of the vehicle caused the server drive to be misreported — a 30-dollar switch to the ground line。
It is recommended that on-site equipment maintenance staff conduct a self-check as follows:
Recording alarm codes and frequency: occasional or ongoing? Are you going to report for the self-censorship phase or as soon as you're ready? This information enables maintenance engineers to quickly locate whether the control cabinet is a problem or a failure. Check the surrounding environment: whether the control cabinet dispersing fan is clogged, whether the workshop power three-phase voltage is balanced, and whether the radio cable is broken. I've had one case in which clients burned three servers, and finally found short circuits for access. Check maintenance records: hanar robotic lubricant has a strict replacement cycle, j4/j5/j6 usually needs to be replenished for 5,000 hours or six months of work, and a chronic shortage of fuel can cause speed-reducing wear and tear, at which point you cannot fix any electrical circuits. Do not dismantle the encoders or the electrics by itself: the servs in the hanar section use absolute location encoders, which require special battery protection and zero-point calibration devices to recover once zero data are lost。
By pre-packaging this information to the maintenance service provider, the other party could ask a few questions of a level that would largely allow it to judge professionalism。
What do you do with that hairy robot that's been repaired
In march of this year, i met with the clients who came to the workshop in kunsan, and their practices are worth mentioning. The customer welds new energy batteries, which are highly accurate for the trajectory, as follows:
The electrical engineers in kunsan told me that they had mature on-site maintenance, commissioning, after-sales technical services, and that each time the repairs were completed, they produced a test report, including currents of the axes, vibration data, precision tests, which also served as a benchmark for subsequent protection。
How do you choose a service provider for brand-built robot maintenance, except for the haina
Long triangle manufacturing plants are often mixed with multiple brands of robotics, and i visited a pressurized plant in kunsan last week, with both fanuc, angawa and kawasaki robots. Such hybrid field-selection service providers are most reluctant to look for a small workshop with only one brand - they may have adapted the aluminum-supplied parameters to the kawasaki e series, where the two brands have a very different inertial approach。
Key criteria are as follows:
How important is the speed of response in selecting service providers in the long triangle
A real scene: last summer, the night shift at a steam plant in shanghai, a welding robot workstation suddenly stopped, and the control cabinet paper srvo-068 dterr. The production line is worth tens of thousands per hour and cannot afford to wait. The service providers they contacted arrived only the following afternoon, and the search found that the pulse encoder data was abnormal and that it took another two days to wait for the spare parts。
After that, their choice changed:
Summary recommendations
Pick out the robot maintenance service, remember three words: look, ask, measure. See if the workshop had a physical test platform, asked about the logic of judgement for each failure and requested post-maintenance test reports. Service factories such as kunsan han-ji depend on the experience of engineers, the depth of spare parts storage and the input of testing equipment. Core data can be validated on-site and maintenance quality can be sustained。
