Abstract

The present invention relates to an automated system for shrinking a tube by heating, which adheres a heat shrinkable tube to an object to be processed. The system comprises: a plurality of jig units that are spaced apart from each other by predetermined intervals and fixate to allow an object to be processed, to be dismounted and mounted; a transfer unit that moves the jig units fixated with the object to be processed at the preset speed; and a heating unit that applies heat to the heat shrinkable tube while the jig units are moved by the transfer unit. The jig units are moved between a first location and a second location by the transfer unit. An X axis is a virtual axis connecting the first location and the second location in a straight line and a Y axis is a virtual axis that intersects with the X axis. According to the present invention, unlike the conventional method where a majority of operators have to operate repeat and manual rotation while the object to be processed is placed next to a heating device, only a handful of operators simply have to fix the object to be processed to the jig unit. Then, the heat shrinkable tube is automatically attached to the multiple object to be processed. Therefore, it is possible to save the time for attaching the heat shrinkable tube to the object to be processed and overall manufacturing costs. So, it is adequate for quickly processing post-processed wire harness, which requires mass production, with consistent quality.

In the automated heat shrinking system 100, the heating unit 40 is arranged so as to be opposed to each other so as to be vertically spaced apart from each other by a predetermined gap between the heat-shrinkable tubes T Therefore, the upper and lower portions of the heat-shrinkable tube T are heated at once so that the heat-shrinkable tube T can be shrunk uniformly to the upper and lower portions to be attached to the workpiece in an even state.

In addition, since the automated heat shrinking system 100 includes the heat insulating member 70 that can be provided at a portion exposed to the outside, it is possible to prevent a safety accident of an operator due to heat generated from the heating unit .
In the present application, the directions of " upper and lower " generally describe the positive direction of the Z axis with reference to the XZ plane shown in FIG. 4 as " up ", and the negative direction of the Z axis as the & . However, the direction of " lower " in the portion described as " bottom " is described as the negative direction of the Y axis with reference to the XY plane shown in Fig.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
