DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIG. 1, a robotic arm 12 is fixed in or on an automatic wire winding machine (not shown) and is controlled by an automatic control system (not shown) to move or rotate in or on the automatic wire winding machine. The robotic arm 12 contains two support members which connect with a guiding device 10 capable of moving relative to the robotic arm 12.

The guiding device 10 according to a preferred embodiment of the present invention comprises a column 20, a cylinder 30, a sleeve 40, a cap 50, two springs 54, three movable arms 60, and a fixing loop 70.

Referring to FIGS. 2 to 5, the post 20 includes a rectangular driven portion 22 extending outwardly from a bottom thereof, an elongated hole 24 and three grooves 26 which are arranged between the bottom and a top of the post 20. The post 20 further includes a first orifice 28 formed on a peripheral wall of each groove 26.

As illustrated in FIG. 1, the post 20 is in connection with three bolts 21 and a connector 16, wherein each bolt 21 inserts through the first orifice 28 of the post 20 so as to fix in said each groove 26, wherein the top of the post 20 inserts through the two support members 14 so as to slidably connect with the robotic arm 12, the connector 16 is mounted on a position of the post 20 over the robotic arm 12 at which the post 20 starts movement relative to the robotic arm 12, and the connector 16 stops a removal of the post 20 from the robotic arm 12.

As illustrated in FIGS. 1 and 6 to 10, the cylinder 30 includes a through hole 31 formed in a fish eyelet shape on a central position of the cylinder 30, and a diameter of the through hole 31 is more than the post 20 so that the post 20 moves reciprocately via the cylinder 30. The cylinder 30 includes two projections 32, and each projection 32 extends out of a bottom of the cylinder 30 so as to move with respect to the driven portion 22.

The cylinder 30 also includes a slot 34 adjacent to the bottom thereof, two first apertures 36 proximate to the slot 34, and three second apertures 38 form on an inner wall thereof adjacent to a top of the cylinder 30. In addition, the cylinder 30 includes a limiter 37 retained with the two first apertures 36 and inserts through the elongated hole 24 of the post 20, and a width of the limiter 37 is less than a distance between two short sides of the elongated hole 24 so as to limit a moving range of the cylinder 30 relative to the post 20. The cylinder 30 also includes three third apertures 33, and each third aperture 33 passes through each second aperture 38 so that a shaft 35 fixes in said each third aperture 33 through said each second aperture 38. Furthermore, said each second aperture 38 is located outside said each groove 26.

With reference to FIGS. 1 and 13, the sleeve 40 includes two trenches 42 located on two ends thereof respectively. When the sleeve 40 is fitted with the post 20, a first screwing element (not shown) is locked in a threaded opening 44 on an outer wall of the sleeve 40 and forces the post 20 so as to fix the sleeve 40.

Referring to FIGS. 1 and 11, the cover 50 includes an eyelet 52 and fits with and moves on the post 20, and the cover 50 is fixed between the robotic arm 12 and the sleeve 40 and is separated from the cylinder 30 by the sleeve 40.

One of the two springs 54 abuts against the sleeve 40 and pushes the cover 50 to move by which the post 20 is driven to move with respect to the robotic arm 12 until the connector 16 is sopped by the two support members 14. Another of the two springs 54 also abuts against the sleeve 40 and pushes the cylinder 30 to move reversely until the limiter 37 is stopped in the elongated hole 24.

As shown in FIGS. 1 and 12, each movable arm 60 includes a hook portion 62 arranged on a first end thereof, a fork portion 64 formed on a second end thereof, and a second orifice 66 defined on a central position thereof. When said each movable arm 60 is accommodated in said each second aperture 38 of the cylinder 30, the shaft 35 inserts through the second orifice 66 of said each movable arm 60, the hook portion 62 is located outside the cylinder 30, and the fork portion 64 enters into said each groove 26 so that said each bolt 21 is located on a central position of the fork portion 64, and the hook portion 62 moves back and forth between a hooking position and a unhooking portion.

As illustrated in FIGS. 1, 14 and 15, the fixing loop 70 is fitted on the cylinder 30 and moves back and forth relative to the post 20. The fixing loop 70 includes a positioning trough 72 formed on a top thereof and flushing with the slot 34 of the cylinder 30 so as to accommodate a key 71 with the slot 30, and the key 71 is locked in the cylinder 30 by a second screwing element so as to stop a rotation of the fixing loop 70 around the cylinder 30.

The fixing loop 70 further includes a slit 74, a C-shaped clamping portion 76 defined between the slit 74 and the top of fixing loop 70, and two third orifices 78 arranged on a mouth of the clamping portion 76, wherein the clamping portion 76 is locked in the two third orifices 78 by a three screwing element so as to decrease a diameter of the clamping portion 76, thus fixing the fixing loop 70.

The guiding device 10 operates in a first travel and a second travel, the first travel represents the two springs 54 pushes the cover 50 and the sleeve 40 outwardly, and the second travel denotes the two springs 54 pushes the sleeve 40 and the cylinder 30 outwardly. Thereby, the two projections 32 of the cylinder 30 moves over the driven portion 22 of the post 20 so as to drive the hook portion 62 of said each movable arm 60 to locate at the unhooking portion.

Referring to FIG. 16, when the two projections 32 are forced by a motor stator (not shown) to drive the cylinder 30 to move with respect to the post 20, a distance between the cylinder 30 and the sleeve 40 is zero so that the cylinder 30 and the sleeve 40 press the two springs 54, the two projections 32 are located abreast the driven portion 22, and the hook portion 62 of said each movable arm 60 maintains at the hooking portion.

In the second travel, the driven portion 22 and the two projections 32 actuate the post 20 and the cylinder 30 to continuously move upward until the sleeve 40 is biased against the cover 50 and to press the two springs 54 between the sleeve 40 and the cover 50.

Meantime, the robotic arm 12 is close to the motor stator, and the fixing loop 70 counterweights the motor stator, so the post 20 supports the motor stator stably as the guiding device 10 guides wire in a wire winding process.

While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
