How to ensure the mechanical accuracy of the winding machine manufacturer's product system

In order to meet the requirements of high efficiency and high output when designing fully automatic winding machines, manufacturers of fully automatic winding machines generally adopt a multi head linkage design in all types of automatic machines, which achieves basic requirements of high efficiency and high output. Moreover, most domestic manufacturers refer to the design of imported models from Taiwan and other places, using programmable controllers as the control core of the equipment, combined with robotic arms The pneumatic control components and execution accessories are used to complete functions such as automatic wire arrangement, automatic foot winding, automatic thread cutting, and automatic loading and unloading of the skeleton. This design of the model not only has high production efficiency, but also greatly reduces the dependence on manual labor. One operator can take care of several such devices at the same time, unlike in the past when a worker had to operate a machine, and the quality of production in this way will be relatively stable, So it is very suitable for processing occasions with high production requirements, as high work efficiency and high-quality packaging can greatly increase production.

In order to ensure the mechanical accuracy of the fully automatic winding machine system produced by the manufacturer of the fully automatic winding machine, it should be emphasized that the coaxiality of the fixed seat and clamping mechanism, as well as the coaxiality of the tail seat and tail seat clamping mechanism, must be ensured first. Under these two prerequisites, the coaxiality of the front and rear fixed seats is required. In an ideal situation, it is required that the axes of the two should coincide. The clamping mechanism shall not allow relative sliding during winding when clamping the core rod, and it is required that the clamping mechanism shall not cause damage to the core rod due to excessive clamping force on the core rod.

For the ball screw, it is required to use a hard connection with the coupling when connecting it to the output shaft of the driving motor, in order to minimize the twisting error caused by the screw during rotation. At the same time, the movement of the horizontal motion workbench also requires high-precision guide rails to support it, ensuring that the screw achieves smooth horizontal transmission without large jumping. This requires the parallelism and spacing of the guide rails, And the levelness of the surface for installing the guide rail must be relatively high. So generally, the installation surface requires scraping and grinding treatment. The smaller the sliding static friction force of the guide rail, the better.

In the winding machine system of fully automatic winding machine manufacturers, asynchronous motors are used for both the winding spindle and the winding spindle. The system consists of a servo module, a frequency conversion module, a displacement counterweight module, a PLC control module, and a human-machine interactive touch screen module. When the system is running online, the take-up spindle uses vector control for active operation, and the control process includes two closed-loop systems. One is the vector control, which is directly connected to the encoder and motor spindle and forms a closed-loop with the frequency converter; One is directly connected to the wire reel shaft after gear reduction, ensuring accurate counting of turns.

The pay-off motor utilizes a combination of PID and bang bang to perform real-time speed matching based on the position of the counterweight module and the speed of the take-up motor. Compared with cylinder matching, this matching method expands the allowable error range of the system and enhances the stable operating range of the system. The wiring system of the system utilizes a servo controller to ensure the precision of wiring. In order to facilitate the loading and unloading of the reel, the system has added an automatic lifting function for the coil in the take-up and pay-off sections. In order to ensure the safety of the system during operation, functions such as left and right limit positions for wire laying, upper and lower limit positions for wire laying and take-up racks, upper and lower limit positions for wire laying racks, upper and lower limit positions for counterweight blocks, and emergency stop have been added.
