Description

[0001] The present invention relates to a shrinkage tube assembling machine,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shrinking tube assembling apparatus, and more particularly, to a shrinking tube assembling apparatus for shrinking a tube, Tube assembling apparatus.

The shrink tube is made of synthetic resin that shrinks by heat. It is also used for grip of baseball bat or handle of motorcycle, but the most used place is used for electric wire or cable to increase the watertightness or to protect the cloth.

Especially in the case of various cables used in the home, the ends of the cable are frequently damaged due to repetition of bending. In order to repair damaged parts in ordinary households, the shrinking tube is cut to a proper length and the damaged part is inserted There is an increasing tendency that the tube is simply shrunk by applying heat to the tube using a dryer.

In recent years, there have been a lot of cases in which a shrink tube is pre-attached before a terminal is connected in a cable production stage so that a damaged portion can be reinforced.

However, in addition to having a relatively small diameter small cable, the cable itself is flexible, and the shrink tube is also flexible. There are many devices for assembling a shrink tube in a pipe, but the work of attaching a shrink tube to a cable Which causes production cost and cost increase.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

2 is a perspective view showing another embodiment of the present invention, in which the shrink tube assembling apparatus 1 according to the present invention includes a shrink tube supply unit 11 and a shrink tube A tube conveying section 12, a cable guide section 13, a cable conveying section 14, and a cable pick-up section 15.

First, the shrink tube supply unit 11 sequentially aligns the shrink tube 100 cut into an appropriate length according to the inner apparatus when the shrink tube 100 is inserted into the hopper, and the aligned shrink tube 100 moves along the shrink tube Picker 121 so as to move to the end of the guide bar 131 of the cable guide part 13. [

When the cable 200 is supplied to the cable guide portion 13, the cable transfer portion 14 allows the cable 200 to move horizontally while allowing the cable 200 to pass through the shrink tube 100, And then the cable is picked up by the cable pick-up unit 15 so as to be movable to the next process.

FIG. 3 is a conceptual view illustrating the operation of the shrink tube transfer part according to an embodiment of the present invention. The shrink tube transfer part 12 includes a shrinkable tube picker (for example, A first motor 123 that vertically feeds the shrinkable tube picker 121 along the path of the LM guide and a second motor 123 that vertically feeds the shrinkable tube picker 121 along the path of the LM guide, And a motor 124 to move the shrink tube 100 on an extension of the cable 200 to be inserted between the guide bars 131 by holding the shrink tube 100 at the shrink tube supply portion 11.

FIG. 4 is a conceptual view illustrating a cable supplying process according to an embodiment of the present invention. FIG. 5 is a partial perspective view illustrating a cable supplying process according to an embodiment of the present invention, The cable 200 is inserted into a gap between the picker 121 and the shrink tube 100 at a distance equal to the outer diameter of the cable 200, A pair of guide bars 131 for exposing both sides of the cable 200 to the outside and a cable inserted through the cable insertion hole 132 fixed to one side of the guide bar 131 and passing through the center, 200) between the pair of guide bars (131).

The supplied cable is inserted between the upper and lower guide bars 131 through a cable insertion hole 132 having a wide entrance and a narrow exit. At this time, the clearance between the guide bars 131 is minimized so that the cable 200 can be straightened .

FIG. 6 is a partial perspective view illustrating a cable transfer process according to an embodiment of the present invention. FIG. 7 is a conceptual view illustrating a cable fixing process according to an embodiment of the present invention. 9 to 11 are conceptual views illustrating a process of transferring a cable into which a shrink tube is inserted according to an embodiment of the present invention. When the cable 200 is inserted into the cable guide portion 13, The cable conveying unit 14 disposed at the lower portion of the cable guide unit 13 includes a plate-shaped conveying panel 141 positioned below the cable guide unit 13 and a conveying panel And a third motor 142 for moving the exposed side of the cable 200 inserted between the guide bars 131 by means of the cylinder 143 Two fixed It is configured to include a cable transfer unit 14 including a speaker cable 143.

The cable 200 is moved along the path of the guide bar 131 while the end of the cable 200 moves along the path of the shrink tube picker 143 The cable picker 143 passing through the shrinkable tube picker 121 can pass through both ends while allowing the shrink tube 100 to pass through the shrink tube 100, Upon completion, the shrink tube picker 121 is moved upward while being opened to prevent the movement of the cable conveying portion 14.

When the assembly of the cable 200 and the shrink tube 100 is completed, the cable conveyor 14 continues to move in the direction in which the cable is conveyed, and then the shrink tube 100, which is conveyed by the cable conveyor 14, A fourth motor 152 for vertically feeding the second cable picker 151 along the path of the LM guide and a fourth motor 152 for vertically feeding the second cable picker 151 along the path of the LM guide, And stops adjacent to the cable pickup section 15 having the motor 153. [

The cable pick-up unit 15 moves to a step of connecting a terminal or a connector to an end of the cable 200 to be advanced later.
