High-precision adjustable and controllable tension wiring device capable of effectively reducing sliding friction

Abstract

The invention discloses a high-precision adjustable and controllable tension wiring device capable of effectively reducing sliding friction. After a wire on a bobbin of the device penetrates a wire passing wheel and is expanded into the linear state, the tension of the wire can pull a spring through the wire passing wheel and a tension rod, rotation of an input shaft of an angle sensor is synchronously driven through rotation of the tension rod and a tension rod rotation shaft, the angle sensor feeds back the angle change of the tension rod to a control computer, the control computer accurately controls the rotation speed of a drive motor, and accordingly the wiring tension of the wiring device is stable. A camera collects wire images, the control computer processes the images, the offsetangle a of a wire is obtained, the control computer controls a sliding table motor to drive a sliding table to move so that the bobbin can correspondingly move, sliding friction between wires due to wire deflection during wiring is effectively reduced, and wire damage in the wiring process is reduced.

Description

technical field [0001] The invention relates to a high-precision tension-adjustable wire routing device capable of effectively reducing sliding friction, and belongs to the field of mechanical automation. Background technique [0002] In the existing industrial production process, the wire needs to be supplied. Currently, the wire is usually supplied by winding on a bobbin, such as an enameled wire. [0003] However, in actual use, some wiring situations require the thread to be unwrapped stably, but the tension of the current wiring device is not stable, and it is impossible to precisely adjust the tension to control the tension, that is, the tension cannot be adjusted accurately. As a result, the wiring device is difficult to achieve high precision and automation. In addition, there are two cases of the skew of the line, one is that the line is skewed on the thread wheel ( figure 2 The center line is not deflected on the thread wheel), such as figure 1 As shown, the th...

[0003] However, in actual use, some wiring situations require the thread to be unwrapped stably, but the tension of the current wiring device is not stable, and it is impossible to accurately adjust the tension to control the tension, that is, the tension cannot be adjusted accurately. As a result, it is difficult for the wiring device to achieve high precision and automation

In addition, there are two cases of the skew of the line, one is that the line is skewed on the thread wheel ( figure 2 The center line is not deflected on the thread wheel), such as figure 1 As shown, the thread is deflected to the left on the thread wheel, such as image 3 As shown, the thread is skewed to the right on the thread wheel; another case is that the thread is skewed on the spool, because the length of the existing spool is long, and the axial position of the spool is fixed, when the thread is slanted on the spool The line is skewed at most of the axial positions, such as Figure 5 As shown, the thread is skewed on the spool (when the thread is not skewed as Figure 4 As shown), the above two situations have increased the sliding friction between the thread on the bobbin and the thread and the sliding friction between the thread and the thread wheel, causing greater damage to the surface of the thread, which is in some cases Not allowed, for example, transformers (especially high-voltage transformers) do not allow the paint film of the enameled wire to be damaged during winding, so as to prevent the insulation performance of the enameled wire from decreasing
