Servo tensioner

Abstract

The invention discloses a servo tensioner which comprises a machine shell, a wire feeding mechanism arranged on the machine shell, a tension adjusting mechanism, a detection device, a controller arranged in the machine shell and a servo motor used for driving the wire feeding mechanism. The wire feeding mechanism ensures that the tension of a winding wire is stable, and therefore the detection device can accurately detect the tension of the winding wire. The tension adjusting mechanism can conveniently adjust the tension of the winding wire passing through the servo tensioner. The servo motorstably drives the wire feeding mechanism, and therefore the winding wire still has stable tension during high-speed operation of the tensioner. By means of a combined armature stator, the winding slotfilling rate reaches 100%, and motor work efficiency is improved. By means of an integrated permanent magnet ring, the unsafe phenomena that installation is difficult, and falling is likely to be caused in the production work procedures are solved. By means of axial inclination magnetizing, air gap magnetic field push consistency is better improved, and motor power output is more sufficient.

Description

technical field [0001] The invention relates to the field of tensioners, in particular to a servo tensioner. Background technique [0002] The tensioner is to ensure that the coil reaches the required tension during the winding process, so that the fired coil is tight enough to ensure that the length and resistance value meet the required technical parameters. With the development of the national economy and the continuous improvement of automated production technology, the quality of coil products has been continuously upgraded. The traditional permanent magnet and mechanical tensioners are gradually unable to adapt to the development of products due to the limitations brought about by their structure and principle. At present, the existing tensioners on the market are all composed of rod-type tension devices and springs.

Problems solved by technology

With the development of the national economy and the continuous improvement of automated production technology, the quality of coil products has been continuously upgraded. The traditional permanent magnet and mechanical tensioners are gradually unable to adapt to the development of products due to the limitations brought about by their structure and principle.

At present, the existing tensioners on the market are all composed of rod-type tension devices and springs. The traditional permanent magnet tensioners and mechanical tensioners have poor stability, which can easily cause the tension rod to swing during the tension detection process, resulting in tension detection. Inaccurate, and the current tensioner on the market is basically passive wire feeding, the tensioner has poor tension stability, high frequency of wire breakage, and low winding quality

During the transmission process of the existing tensioner using the wire feeding wheel, the winding wire is only sent to the tension rod around the small half of the wire feeding wheel, which is easy to cause the winding wire to slip, thus causing distortion of the tension detection

[0003] In addition, the existing servo tensioner still has the problem of tension adjustment, which has the following disadvantages: one is that the range of tension adjustment is small during the work process, the tension adjustment is inconvenient, and the tension cannot be adjusted in a large range; During the working process, there is the problem of unstable winding wire tension and poor stability, and it is difficult to adjust the winding wire in real time to provide constant tension
