Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art. It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

Referring to FIG. 1 to FIG. 12, the figures show the preferred structure of the wire stripper provided by the embodiment of the present invention. As shown in the figure, the wire stripper includes: a support frame 1 , a controller 2 , a clamping device 3 , a rotating device 5 , a knife control device 4 , a cutter 6 , a first detection device 7 and a second detection device 8 . The support frame 1 may be a frame structure, which may include: a top plate 11, a bottom plate 12 and two side plates 13, the top plate 11 is parallel to the bottom plate 12, the two side plates 13 are parallel, and the two ends of the top plate 11 are parallel to the two side plates 13. The side plates 13 are connected, and both ends of the bottom plate 12 are also connected with the two side plates 13 to form a quadrilateral frame, and each side plate 13 is provided with an opening to form a hollow state.

The clamping device 3 , the knife controlling device 4 and the rotating device 5 are all arranged on the support frame 1 , and the clamping device 3 is used for clamping or loosening the wire 9 . The cutter 6 is arranged on the cutter control device 4, and the cutter control device 4 is used to drive the cutter 6 to move forward or backward. The rotating device 5 is used to drive the support frame 1 to rotate, thereby driving the clamping device 3 and the knife control device 4 to rotate together.

The first detection device 7 is disposed on the cutter 6 to detect whether the cutter 6 is in contact with the aluminum core of the wire 9 . Exemplarily, the first detection device 7 is a capacitance sensor. When the cutter 6 peels off the insulating sheath and contacts the aluminum core of the wire 9, the capacitance of the cutter 6 itself will change, and the capacitance sensor will sense the change, and then Send out the in-feed in-position signal. In specific implementation, when the cutter 6 is in contact with the aluminum core of the wire 9, since the cutter head itself is insulated from other metal components of the wire stripper, its capacitance is small. Once it contacts the wire, the capacitance will suddenly increase by 2- 3 orders of magnitude.

The second detection device 8 is arranged on the knife control device 4 to detect whether the insulating skin of the wire 9 is completely peeled off. Exemplarily, the second detection device 8 is a color sensor. Since the color of the insulating skin and the wire 9 is different, the peeling condition of the insulating skin can be judged by detecting the color. When the wire 9 has an eccentricity problem and the insulating skin is not completely peeled off, the second detection device 8 can sense the color difference between the metal color and the wire 9 in real time, and send a signal to continue feeding.

Specifically, only when the first detection device 7 detects that the cutter 6 is in contact with the aluminum core of the wire 9, and the second detection device 8 detects that the insulation of the wire 9 is completely peeled off, the driving of the cutter 6 can be stopped. . If only one satisfies the condition, the cutter 6 moves on.

The controller 2 is also used to control the knife control device 4 to drive the knife 6 to retreat when the insulating sheath of the wire 9 is cut to a preset length, and to control the retraction to stop when the knife retracts to a preset position. In the process of retracting the knife, the cutting edge of the cutter 6 deviates from the center of the wire 9, and the insulating skin will gradually become thinner until the insulating skin is cut off. During specific implementation, the preset position may be determined according to the actual situation, which is not limited in this embodiment.

It can be seen that in this embodiment, the clamping device 3 clamps the wire 9, and the controller 2 controls the rotation device 5 to rotate to drive the clamping device 3 and the knife control device 4 to rotate around the wire 9 together. At the same time, the knife control device 4 drives the cutting The knife 6 moves forward. When it is detected that the cutter 6 is in contact with the aluminum core of the wire 9 and the insulation of the wire 9 is completely peeled off, the knife control device 4 stops driving the cutter 6 to move forward, and the cutter 6 continues to rotate around the wire 9, thereby Cutting the insulation of the wire 9, the operation is simple and convenient, and the position of the cutter 6 can be automatically adjusted, which is suitable for stripping wires of various thicknesses, and realizes the automatic cutting of the insulation. There is no need to manually adjust the position and depth of the cutter. The automatic self-adaptive stripping of the wire saves time and labor, reduces the labor intensity of the operator, and can accurately strip the strip, improve the cutting precision, and solve the problem of the manual stripping of the insulated wire in the prior art, which easily leads to complicated and time-consuming operations.

The preset length is determined according to the actual situation, which is not limited in this embodiment. In this way, the length of the insulating skin can be accurately determined, and then the timing of the retreat of the cutter 6 can be accurately determined.

The third detection device 10 is also used to determine the position of the rotating device 5, and the controller 2 is also used to control the rotating device 5 to be calibrated to the initial position according to the position of the rotating device 5 after the cutter 6 retreats, and when the rotating device 5 is placed in the initial position When in position, the rotating device 5 is controlled to stop rotating. The initial position is the position before the clamping device 3 clamps the wire 9 .
