01 "O" ring spell
In addition to the oil seal problem of the reducer itself, the robot manufacturer will also have an impact on the planning and installation of the reducer components, due to the sealing of the reducer, in addition to the oil seal, there are also O-rings.
O-ring is a standard part that is very common in product sealing planning, and there are also corresponding national standards that can be queried. In the robot reducer, most manufacturers will match the O-ring and process the O-ring groove. In some cases, the manufacturer is not equipped with O-rings, and there is no O-ring groove on the reducer, so it is necessary to plan on the device flange. However, due to capillary phenomenon, the base oil will still be soaked.
02Installation planning and installation process
Why are many domestic manufacturers very confused about the use of the same HD, Teijin reducer, but it is damaged first than the four families? This may be the fault of the immature installation process, the structure can be intuitively disassembled and seen and imitated, but the installation plan and process cannot be seen in the robot, and even in the drawings. Mature robot manufacturers will have professional process engineers who specialize in the installation of robots, including reducer installation.
03 Servo control
Servo control has a great influence on the reducer. Here the servo control includes the whole system of motor, drive, and controller, and the servo function is poor, perhaps if the servo is not adjusted well, the motor is easy to shake at different speeds or loads, and even if the mechanical planning is not good, resonance is often generated. In the selection of servo, it is also the local area that domestic robots do not pay much attention to, and domestic robots focus on cost performance, but in actual operation, many will become more focused on price, rather than function.
04 Overtime application
Can robots work without sleep? Actually, it's a misunderstanding. First, the robot needs to rest, and it is generally recommended that the robot rest for 1 hour every 12 hours of operation, of course, this is for a relatively poor working environment, if the robot itself is very comfortable, then 24 hours of running is not impossible; Second, the robot is required to be maintained, and the robot is also a kind of fine equipment, which needs to do some maintenance on a regular basis to reduce the loss rate and extend the service life, which is the same as the car.
05 Overload application and impact
This situation is relatively common in China. Each robot has a planned load and inertia, pay attention to the load and inertia of the two elements, many customers will only look at the load, not the inertia, so sometimes the load is not exceeded, but the inertia is much exceeded, the robot will also have various problems.
Another problem is the impact problem, which is the most tangled place. There are two kinds of shocks, one is a bump, and the other is an emergency stop, including a shooting emergency stop or a sudden power outage. The impact is relatively good for the RV, the RV is much more rigid, of course, the number of impacts can not be too much, but about harmonics, the impact is very sensitive. Bumps are generally accidents in the process of debugging or production, which are generally accidents, not subjective, but emergency stops are subjective non-standard operations for many times.
