MX machinery:
In our daily life, we need toothbrushes, combs, cleaning the room, vacuum cleaners, including your towels and your winter clothes, all of which are inseparable from the application of the flocking industry. The hair planting machine is an indispensable machine in industrial production and a great industrial invention.
Usually, the brush is an inseparable tool in daily life, and it is also a commonly used accessory in industrial production. The brush industry has a very broad market prospect. Therefore, brush manufacturers are making great efforts to improve production capacity and production efficiency. Kung fu also puts forward high requirements on the processing technology and processing efficiency of the hair planting machine.
Drilling machines and hair planting machines are the most basic production machines in the brush industry, and their technological improvements and enhancements have received great attention.
The drilling/hair-planting machine can be used to make various daily
brush machine factory, such as toothbrushes, brooms, shoe brushes, wooden brushes, wire brushes, copper wire brushes, toilet brushes, etc. In the field of industrial brushes, such as brush rollers, disc brushes, etc. are also inseparable from drilling machines and hair planting machines.
Drilling/hair planting machines can be divided into different types according to different classification standards. According to the number of shafts, it can be divided into two shafts, three shafts and more than four shafts; according to the function, it can be divided into hair planting machine, drilling machine and drilling and planting integrated machine. At present, two-axis and three-axis machines are commonly used, because most products only need to use two-axis and three-axis machines, and machines with more than four-axis are used to produce some special-shaped brushes.
1. Program planning of high-speed toothbrush hair planting machine:
At present, the electric control system structure of toothbrush hair planting on the market is mainly divided into single chip control system or CNC numerical control system. Among them, the control system of the single-chip microcomputer is mainly based on the integrated supporting services of the automation system manufacturer, supplemented by the independent research and development of the toothbrush equipment manufacturer. The CNC systems with better performance are mostly imported brands such as Delta's PUTNC-H2P and Europe and Japan.
The important point of CNC numerical control is to control the pulse command signal of the axis to realize servo drive, usually four-axis control output. Delta's CNC can realize only two-axis output, and the servo of the other two axes can be completed by DuLi. Toothbrush hair planting machine requires the system to be able to It is enough to realize two-axis interpolation operation. The four sets of servo drive models are Zhongda's B series ASDA-B AC servo system, with a power of 400W, and the drive has a variety of functional controls. The spindle motor inverter model is Zhongda's VFD-S with a power of 400W.
Second, the main points of toothbrush hair planting machinery debugging:
The difficulty in the development of the solution is the joint debugging of the electromechanical system, the most important of which is the adjustment of the servo gain. Among the four servo axes, the X axis and the Y axis are relatively stable due to the relatively stable mechanical inertia of the screw drive structure, and the debugging is relatively easy, and the bandwidth can generally be adjusted to more than 130HZ. The Z-axis of the flap is a rotating axis, and there is centrifugal force in high-speed rotation. If the frequency bandwidth is simply set to a high value, the motor will vibrate when it starts and stops. At this time, the position smoothing filter parameter can be turned on to remove the vibration.
Relatively speaking, the mechanical structure of the cam mechanism of the hair changing U-axis makes the debugging and comparison difficult. In addition, the mechanical rigidity of the U-axis is not good. When the motor is running, the inertia ratio changes greatly, the output current of the motor also changes greatly, and the parameters cannot be adjusted. Well, when the motor is running left and right, this shaft is either vibrating or whistling, or sluggish. To do this, it is necessary to apply the resonance suppression function of the B series ASDA-B AC servo system. Gain resonance suppression principle for systems with resonance.
When the low-pass filter is increased from 0, the B.W. will become smaller and smaller. Although the resonance problem is solved, the response bandwidth and phase boundary of the system are also reduced, and the system will become more unstable. If the resonance frequency can be known, the band rejection filter can directly remove the resonance amount. It is usually known how much resonance suppression is, and the effect of using a band-reject filter will be better than that of a low-pass filter. However, if the resonance frequency drifts with time or other factors, and if the drift is too far, then it is not suitable to use a band-reject filter. . The problem caused by the operation of the U-axis of this equipment is that the resonance point is elegant. The use of the P2-25 low-pass filter is better, and its parameters are set to be large. In addition, the position accuracy requirements of this axis are not too high, so the problem is solved. .
