Multi-spindle clamping device for automatic stator coil motor winding machine

Automatic winding machine of multi-axis clamping equipment can mainly overcome the shortcomings of the existing technology, chip inductors, built-in capacitors and built-in resistors are one of the three major area-type electronic components, is coiled by the wire a circle close to a circle on the insulating sleeve, the insulating tube can be hollow, can also include the transformer core or magnetic powder probe core. At this stage, most companies in China, the real inductors and other electronic components of the line of wire glue is all the choice of human actual operation method, consuming a large number of manpower, high efficiency is not high, the product quality can not be effectively ensured. The traditional method of wire wrapping is to first hang one end of the transmission wire on the top of the product workpiece in a concave groove, gradually wrap the wire, after the winding is complete, and then hang the transmission wire terminal device on the top of the product workpiece in another concave groove, such a way of hanging the wire there is a product workpiece invasion of tin to produce a broken circuit, resulting in the generation of substandard products.
The working principle of AC frequency converter: Frequency conversion technology is a technology that changes the frequency of switching power supply according to the frequency converter, and then changes the speed ratio of AC asynchronous motor. According to the inverter to carry out the conversion of AC to DC power first, and then according to the inverter to carry out the conversion of DC to AC power, and then suppress the speed ratio of the AC motor. The manipulation of the inverter by the series of products of the new project of the automatic protection equipment of the winding machine is to use the simulation voltage of the keyed inverter to manipulate the frequency of the inverter’s exported switching power supply, so that the speed ratio of the AC motor shifts after the change of the exported switching power supply frequency.

And the speed ratio of the three-phase asynchronous motor is decided by the point frequency, the extreme number of motors and the turndown rate. The asynchronous motor’s turndown is the motor’s magnetic flux and the motor rotor through the electric flow in the middle of the mutual influence and occurrence, in the fixed frequency, if the voltage is certain and only reduce the frequency, then the magnetic flux is too large, the magnetic control circuit saturation state, more serious when the motor will be damaged. Therefore, the frequency and voltage should be changed proportionally, that is, the frequency should be changed while the output voltage of the inverter is controlled, so that the flux of the motor can be maintained to prevent the weak magnetism and magnetic saturation from being caused. Because the general inverter generally choose V/f manipulation, that is, DC transformer frequency conversion type method variable speed, change the frequency and voltage to make the best motion control method. Therefore, the AC motor speed control method is selected, AC motor speed control is to change the frequency of the motor motor stator switching power supply, and then change its 歩 stable adjustment method. Its characteristics: ① high efficiency, no additional loss in the whole process of variable speed; ② wide range of applications, available to cage asynchronous motor; ③ variable speed range, hard features, high precision.
