MI cables (MC) with various outer diameters can be mounted and detached interchangeably. This will be described in more detail below.

The spacing between the above-described two chucks 126 makes it possible to sufficiently accommodate the length of the end of the MI cable to be stripped.

The above-described elevating driving unit is configured to include a vertical frame, elevating member, a third driving motor, and the above-described guide.

The elevating member 130a includes a rotary blade 131 positioned above the above-described chuck, and an electric motor M for rotating the rotary blade 131 by being coupled to the other side of the rotary blade (not shown in the drawing). Is combined through. The above-described cut-out portion is a portion obtained by cutting the surface of the vertical frame 112 so that the electric motor M can be moved up and down together with the elevating member 130a.

Accordingly, the rotary blade 131 can be rotated by the electric motor M, and the electric motor M can be raised and lowered in the vertical frame 112 together with the elevating member.

In addition, the above-described elevating member (130a) is helically coupled with the drive shaft (128a) of the third drive motor (128) fixed to the above-described vertical frame (112) to interlock with it when the third drive motor (128) is driven. It is raised and lowered along the guide 112a.

Reference numerals 120b and 130b in FIGS. 1 to 5 denote touchers coupled to both members 120a and 130a described above. When both touches 120b and 130b move together with both members 120a and 130a, when the first and second position sensors 114a and 114b and 115a and 115b sense both touches, both members ( 120a) Controls the movement of (130a) (stop and forward/backward). This will be described in more detail below.

The first to third driving motors described above may be either a pulse motor or a stepping motor, and a rotation speed and a rotation speed are controlled by a pulse value.

The above-described pulse value is controlled by the controller in such a manner that the pulse value is increased or decreased from the position sensor 114a, 115a on one side to the position sensor 114b, 115b on the other side or vice versa from the initial value.

Accordingly, the number of rotations of the first to third drive motors can be controlled by a specified pulse value, and as a result, it is possible to precisely move and rotate the forward/reverse member, the elevating member, and the driven pulley to a desired position.

The above-described MI cable (MC) sheath removal device 100 sets the position of the rotary blade 131 to set the starting position of the rotary blade 131 so that there is no error in the cutting depth due to wear of the rotary blade 131 Includes means.

As an embodiment of the above-described positioning means, the light-emitting and light-receiving sensors 131a and 131b that are spaced apart from the upper surface of the bearing member 123b, and the pulse applied to the third driving motor when the sensing signal of the light-receiving sensor is detected. The value is stored in the memory as the starting position value of the rotating blade.

In this way, by programmatically determining a control value from the starting position to the depth at which the rotating blade is to be removed, the control unit can control by applying a pulse value corresponding to the difference value between both values to the third driving motor.

In this way, the control value from the starting position to the depth to be removed is programmatically determined by the control unit, and a pulse value corresponding to the difference between both values is applied to the third driving motor to control it.

Meanwhile, the above-described both chuck 126 has the same structure, and thus will be described through the chuck on one side.

The chuck is composed of a chuck with a thread whose outer diameter is gradually enlarged, an inner diameter through which an MI cable passes, and a chuck divided into equal angles, and a nut helically coupled to the chuck.

When the MI cable is inserted into both inner diameters of the chuck and then the nut is screwed into the thread of the chuck, the inner diameter of the chuck is axially diameter or enlarged in the radial direction inward/outward by the fastening force, so that the MI cable can be mounted and separated. .

The above-described rotary blade 131 is a disk-shaped tool with a thin thickness and embedded with industrial diamonds, and removes the outer shell of the MI cable by rotation when the electric motor M is driven.

Hereinafter, a method of removing the shell of an MI cable (MC) according to the present invention will be described in detail with reference to FIG. 7.

Referring to FIG. 8, FIG. 8 is a configuration diagram of a control unit for controlling the skin removal device. The control unit includes a model for each MI cable size 31, a specification selection unit 30, a memory unit 60, and a stripping type selection unit 20. ), the display unit 40 and the first to third driving motors and the electric motor driving unit 50 are controlled by the control unit according to the control logic.

The model (outer diameter) of the MI cable of the specification selection unit 30, the length value and the depth value of the terminal to be removed are previously stored in the memory unit 60, or the user uses an input means such as a keyboard or a touch pad. Can be entered directly.

The above-described memory unit 60 refers to a semiconductor capable of updating the above-described position setting value and information (terminal length and depth values to be removed) of the above specification selection unit 30.

The above-described skin removal method selection unit 30 is to include a button (or switch) for selecting a removal type of the shell when removing the shell of the cable, and the stripping type is either straight or spiral through the button. You can choose Therefore, the control unit controls the skin removal device according to the control logic programmed in advance in response to the selection of the button.

For example, when a straight stripping is selected by the button described above, the control unit 10 determines the model of the MI cable determined by the user or selected by the user, the thickness of the outer sheath of the model, and the length to be removed. After removing the outer shell of the MI cable with the model (outer diameter) of the cable stored in 60), the thickness of the outer shell of the model, and the length of the shell to be removed, the MI cable MC is then rotated 180° as shown in FIG. 7A. As shown, the outer sheath of the cable is removed in the longitudinal direction.

In such a manner, when the button is set to "spin off" and operated, the control unit 10 rotates through the driving pulley, the driven pulley, and the chuck 126 while rotating the outer sheath of the MI cable MC as shown in FIG. 7B. They are removed in a spiral shape together.

The above-described display unit 40 encompasses a display device such as a liquid crystal or a monitor that visually outputs the selection or input value information of the above-described specification selection unit.

The above-described driving unit 50 is collectively referred to as the first to third driving motors and electric motors described above, and is controlled by the control unit 10.

A method of removing the shell of the MI cable MC according to the present invention will be described with reference to FIG. 8.

Prior to the detailed description, it is assumed that operation information stored in the memory unit through the specification selection unit is specified by selection, and an MI cable MC of a specific size is mounted on both chucks 126.

In addition, the straight stripping or spiral stripping selected by the user when removing the cover of the MI cable (MC) differs in the shape of the MI cable removed by the rotary blade, but the stripping method is the same, so the following is removed by the straight stripping method. This will be explained through the method of removing the termination of the MI cable.

In addition, the elevating member and the forward/reverse member are controlled by the control unit in a state in which both position sensors 114a and 115a sense the touches of both members 120a and 130a, that is, at the initial position. (10) The operation starts when the main switch is turned on.

The control unit,

The initialization step, the step of setting the starting position of the rotating blade, the stripping step of stripping according to the setting conditions of the specification selection unit with the aligned MI cable, and the step of separating the rotating blade from the MI cable are automatically performed by the control logic of the program. It is done with.

The above-described initialization step is to install the initial position of the rotating blade and the MI cable, and is to programmatically calculate the distance to be moved based on the initial position.

The initializing step is a process in which the control unit controls the first and third driving motors so that the elevating member and the forward/reverse member are moved to a position where both position sensors 114a and 115a sense both touches. When it is determined that the positions of the elevating member and the forward/reverse member are positioned in an initialized state by sensing of both sensors, the control unit performs a step of setting the starting position of the rotating blade.

In the step of setting the starting position of the rotating blade, a process of controlling the elevating member and the forward/reverse member to move until the position sensors 114b and 115b are sensed by driving the first and third driving motors by the control unit. Say.

By this process, the positioning means of the forward/reverse member is located under the rotary blade, and the elevating member is disposed close to the MI cable.

The control unit supplies power to the third driving motor and the driving motor (M) to rotate the rotary blade 131 (Fig. 1) while rotating by the positioning means [light emitting and receiving sensors 131a, 131b (Fig. 5)]. The blade is controlled to move until it is sensed, and when the positioning means senses the rotating blade, the pulse value applied to the third driving motor 128 is stored in the memory as the starting position value, and the driving motor is stopped. While doing so, the third driving motor 128 is rotated to the sensing position of the position sensor 114b so that the elevating member is positioned.

By this process, the starting position of the rotating blade is set, and the rotating blade is separated from the positioning means.

The MI cable alignment step described above is a process for arranging the MI cable under the rotating blade, and is implemented by rotating the first driving motor based on the position sensor 114b through a preset pulse value.

In other words, the rotating blade is vertically arranged on the outer shell of the MI cable located under the rotating blade.

The above-described stripping step refers to a process of removing the outer shell of the MI cable by moving the elevating member from the starting position to a set depth and rotating the blade, and the control unit determines the difference value of the set depth value based on the starting position value. It can be implemented by converting into a pulse value to control the third driving motor, and driving the first driving motor to a pulse value corresponding to a set length value.

Therefore, while the rotating blade is rotated in a fixed state, the MI cable moves together with the forward and backward members by the first drive motor, so that the shell is removed by the rotating blade.

When the set length is removed, the controller controls the second drive motor through a pulse value so that the chuck rotates 180 degrees, and then controls the first drive motor to rotate in the same manner to rotate in the reverse direction.

In this way, the outer shell of the MI cable MC is removed with the length and depth set by the user.

At this time, if the stripping type is selected as "spiral stripping" and operated, the control unit controls the chuck to rotate continuously, so that the set length, depth, and spiral shape are removed.

When the outer sheath of the MI cable is removed in a set form, the control unit controls the driving motor that drives the rotating blades to stop, and at the same time moves the third driving motor to the position of the position sensor 115b where the position sensor can sense the elevating member. Control to stop after controlling.

It should be understood that the MI cable sheath removal device and its control method described above are not limited to the above-described configuration and control method, and all or part of the components of the embodiments may be selectively combined by the manufacturer, and the above description The embodiments of the present invention posted in the present invention are those of ordinary skill in the technical field to which the present invention pertains to be able to implement various examples of changes or applications, but such examples of changes or applications have the true meaning intended by the present inventors.
