Detailed Description

The structure of the present invention will be further described with reference to the accompanying drawings and preferred embodiments of the present invention.

Referring to fig. 1 and 11, the present invention:

a wire distributing and twisting device for double core wires comprises a frame 1, a carrying platform 11 horizontally arranged on the frame 1, a wire feeding mechanism 2 used for longitudinally clamping and horizontally and sequentially conveying the double-core wires, a wire pressing mechanism 3 transversely arranged above the rear side of the wire feeding mechanism 2 and used for pressing the end parts of the double-core wires against the wire feeding mechanism 2 to prevent the end parts of the two-core wires from moving under the action of external force, a straightening mechanism 4 arranged on the rear side of the wire feeding mechanism 2 from left to right in sequence along the moving direction of the double-core wires and used for straightening the end parts of the two-core wires, a thread separating mechanism 5 for separating the two straightened thread feet, a thread twisting mechanism 6 for twisting the two separated thread feet, the wire stripper comprises a peeling mechanism 7 for peeling off the insulation skin at the ends of the twisted two wire legs, a trimming mechanism 8 for trimming the ends of the two wire legs exposed out of the metal wire after peeling, and a discharging mechanism 9 for taking off the trimmed double-core wire from the wire feeding mechanism 2.

The double-core wire is sequentially driven by the wire feeding mechanism 2 to transversely move on the carrier 11, and the wire ends of the double-core wire are tightly pressed on the wire feeding mechanism 2 by the wire pressing mechanism 3, so that the double-core wire is prevented from moving when a wire foot at the end part of the double-core wire is subjected to an external force. In the process that the double-core wire is driven by the wire feeding mechanism 2 to move transversely, the two wire foot ends of the end parts of the double-core wire are straightened by the straightening structure 4, so that the two wire foot ends are prevented from being bent or twisted downwards to influence the subsequent wire foot processing operation. Then the two straightened thread legs are separated by the thread separating mechanism 5, so that the two thread legs are prevented from being dislocated or overlapped to influence the subsequent thread twisting treatment. The two separate legs are then twisted by the twisting mechanism 6 to present a twist-like configuration at the two legs at the end of the dual core wire to increase the strength and reliability of its connection to the plug end. Then the insulation skin at the end parts of the two separated wire pins is peeled off by the peeling mechanism 7 to expose part of the metal wire, so that the double-core wire is convenient to connect the plug and other parts. Then, the metal wires exposed from both the pin ends are cut by the cutting and aligning mechanism 8, and the assembly is prevented from being affected by the misalignment of the pin ends when components such as a plug are assembled. And finally, the processed double-core wire is taken down from the wire feeding mechanism 2 through the unloading mechanism 9 so as to be convenient for product collection and arrangement.

Specifically, a wire feeding drive motor 219 is fixedly connected to a rear side position of a left end portion of the stage 11 in the longitudinal direction, and a rotation shaft of the wire feeding drive motor 219 is fixedly connected to a rear end of the first rotating roller 211 in the axial direction.

Specifically, referring to fig. 3, each of the pressing line clips 22 of the present invention includes a clip base 221 longitudinally and fixedly connected to the transmission chain 218, a line groove 222 for limiting and accommodating the end of the dual core line is longitudinally arranged on the clip base 221, a limiting plate 223 is transversely hinged on the clip base 221, the lower portion of the left end of the limiting plate 223 is matched and pressed in the line groove 222 to limit and press the end of the dual core line on the pressing line clip 22, the right end of the limiting plate 223 is elastically hinged on the clip base 221, and a rubber head 224 for pressing the dual core line in the line groove 222 is arranged on the lower surface of the left end of the limiting plate 223.

In a normal state, the limiting plate 223 stretches upwards under the action of elastic force, so that the left end of the limiting plate 223 leaves the wire slot 222, and an operator can conveniently place the double-core wire in the wire slot 222 longitudinally.

Further, referring to fig. 3, the positioning thread separating piece 23 of the present invention is fixedly connected to the rear end surface of the cartridge holder base 221 by vertical and horizontal threads. The positioning and branching piece 23 specifically includes two positioning pieces 231 and a branching piece 232 which have the same external shape and are in a rectangular piece structure, and the positioning piece 231 is clamped between the branching piece 232 and the rear end face of the cartridge holder base 221. The upper ends of the positioning piece 231 and the branching piece 232 are correspondingly provided with a first opening 233 and a second opening 234, the size of the opening of the first opening 233 and the second opening 234 is matched with the diameter of the double-core wire, and the opening ends of the first opening 233 and the second opening 234 are further provided with flaring structures 235 which are beneficial to clamping the ends of the double-core wire into the first opening 233 and the second opening 234 from top to bottom.

A branching needle 236 for separating two legs at the end of the double core wire is vertically arranged at the concave middle position of the second opening 234 of the branching sheet 232.

In actual use, after the positioning wire distributing piece 23 is fixedly connected to the rear end face of the clip base 221, the first opening 233 and the second opening 234 are longitudinally and correspondingly located at the rear side of the wire slot 222, a pressing face 225 (shown in fig. 3) for pressing and clamping the end of the dual-core wire on the clip base 221 by the wire pressing mechanism 3 is arranged between the positioning wire distributing piece 23 and the wire slot 222, and the depths of the first opening 233 and the second opening 234 and the bottom of the wire slot 222 are flush with the pressing face.

At the initial operation time of the wire feeding mechanism 2, the wire pressing clip 22 at the leftmost end is not yet pressed by the limiting part of the wire pressing mechanism 3, and the limiting plate 223 is opened under the action of the elastic force to expose the wire slot 222. When in use, the double-core wire is longitudinally placed on the transmission belt 213 of the wire feeding mechanism 2 and supported by hand or automatically through a wire feeding device, and the rear end part of the double-core wire is correspondingly placed in the wire groove 222 of the wire pressing clip 22. At this time, the rear end of the dual core wire is limited and locked in the first opening 233 and the second opening 234 of the positioning branching piece 23 under the guidance of the flaring structure 235, and the rear end of the dual core wire is longitudinally pushed to the front end surface of the branching needle 236 of the branching piece 232, so as to position the end of the dual core wire and prevent the end of the dual core wire from protruding out of the branching piece 232. Meanwhile, the two legs at the rear end of the double-core wire are respectively positioned and limited at two sides of the wire separating needle 236, so that the two legs are separated.

Subsequently, the wire feeding driving motor 219 of the wire feeding mechanism 2 is started to transmit torque to the first rotating roller 211, and then the driving chain 218 is driven to rotate through the driving belt 213, the first gear 216 and the second gear 217, so as to drive the wire pressing clip 22 longitudinally and fixedly arranged on the driving chain 218 at equal intervals to horizontally and transversely move.

The positioning wire-separating sheet 23 on the wire-pressing clip 22 can accurately position and clamp the end parts of the double-core wires, and the design of the wire-separating needle 236 can ensure that two wire feet of the fixed end part of the cable can be effectively separated, thereby creating conditions for the subsequent smooth wire-separating and twisting, and the positioning double-core wire end parts are accurate and convenient to operate.

Further, referring to fig. 4, the wire pressing mechanism 3 of the present invention includes two vertical plates 31 vertically and longitudinally fixed on the carrier 11 and respectively located at the left and right ends of the rear side of the wire feeding mechanism 2, a vertically and horizontally screw-fixedly connected between the front end surfaces of the two vertical plates 31 is a pressing plate 32 which is vertically and horizontally adjustable and located above the limiting plate 223 of the wire pressing clip 22 of the wire feeding mechanism 2, an arc guide surface 321 is provided at the lower portion of the left end of the pressing plate 32 corresponding to the operation start end of the wire feeding mechanism 2, a fixing strip 33 is horizontally and horizontally screw-fixedly connected to the rear plate surface of the pressing plate 32, a downwardly driven pressing cylinder 34 is vertically and fixedly connected to the left and right ends of the fixing strip 33, the piston rods of the two pressing cylinders 34 vertically penetrate through the fixing strip 33 to extend downward, a pair of movable strips 35 corresponding to the lower portion of the fixing strip 33 is horizontally and horizontally connected between the end portions of the piston rods of the two pressing cylinders 34, the movable strip 35 is vertically connected with a plurality of abutting columns 36 which are respectively and correspondingly arranged at the front sides of the straightening mechanism 4, the wire separating mechanism 5, the wire twisting mechanism 6, the peeling mechanism 7 and the slicing mechanism and are used for abutting the end parts of the double-core wires against the abutting surface 225 of the clip base 221 under the driving of the abutting cylinder 34 so as to prevent the double-core wires from moving when the wire legs are acted by external force.

Furthermore, in order to ensure the stability of the up-and-down movement of the movable bar 35, at least two limit stabilizer bars 37 are movably connected between the movable bar 35 and the fixed bar 33, the lower ends of the limit stabilizer bars 37 are fixedly connected to the movable bar 35, and the upper ends of the limit stabilizer bars 37 movably penetrate through the fixed bar 33.

It should be noted that the radian guiding surface 321 disposed at the lower portion of the left end of the pressing plate 32 can gradually press the rubber head 224 at the left end of the limiting plate 223 against the end portion of the dual core wire in the process of the left-to-right lateral movement of the pressing clip 22, and the position of the left end edge of the pressing plate 32 should be located at the right side of the left end edge of the transmission belt 213 and the transmission chain 218, so as to ensure that at least one position of the pressing clip 22 is reserved outside the left end of the pressing plate 32, so as to place the dual core wire.

In actual use, the pressing line clip 22 at the leftmost end is not restricted by the pressing of the pressing plate 32 for placing the double core wire. After the double-core wires are placed, the wire pressing clip 22 on the wire feeding mechanism 2 moves laterally from left to right along with the transmission chain 218, and then the limiting plate 223 on the wire pressing clip 22 is gradually folded under the guidance of the radian guiding surface 321 at the lower part of the left end of the pressing plate 32, and finally the ends of the double-core wires are clamped in the wire grooves 222. After the dual core wire is moved to the subsequent corresponding station by the wire feeding mechanism 2 along with the wire pressing clip 22, the piston rod of the pressing cylinder 34 extends vertically downward to drive the pressing column 36 to move to the pressing surface 225 at the rear end of the clip base 221 until the pressing column 36 presses the end of the dual core wire against the pressing surface 225. After the pressing column 36 presses and fixes the double-core wire, no matter the wire legs are straightened, separated, twisted, peeled or cut, the double-core wire cannot move under the action of external force, the accuracy and reliability of the wire legs processed at corresponding stations are ensured, the error rate is low, and the generation of defective products is effectively reduced.

It should be noted that, since the legs of the rear end portions of the dual core wires clamped by the wire feeding mechanism 2 longitudinally extend to the rear side of the pressing plate 32, the front ends of the two vertical plates 31 are correspondingly provided with clearance positions 311 for the end portions of the dual core wires and the legs to pass through.

Meanwhile, the vertical height of the pressing plate 32 can be adjusted as required, if the cable is thick, the vertical height can be adjusted upwards, if the cable is thin, the vertical height can be adjusted downwards, and as long as the bottom of the pressing plate 32 can press the left end of the limiting plate 223 on the wire pressing clip 22 against the wire groove 222 in the operation process of conveying the double-core wire from left to right by the wire feeding mechanism 2, so that the end of the double-core wire is limited in the wire groove 222 through the rubber head 224.

It should be noted that the pressing plate 32 of the present invention only slightly presses the wire pressing clip 22 to ensure that the two-core wire is locked in the wire slot 222. If the height of propping the clamp plate 32 excessively low of adjusting, its limiting plate 223 of line ball clip 22 in by left right lateral shifting in-process can be supported the serious wearing and tearing of clamp plate 32, causes the damage of line ball clip 22, also can cause the damage of two heart yearns because of the limiting plate 223 supports the dynamics of pressing two heart yearns too big simultaneously, must not compensate. Therefore, the pressing cylinder 34 drives the movable strip 35 to drive the pressing column 36 to further limit and press the double-core wire, so that the reliability of wire fixing is improved, and the double-core wire is effectively prevented from moving when the wire pin is acted by external force.

Further, referring to fig. 5, the straightening mechanism 4 of the present invention includes a driving assembly fixedly disposed at the left end position of the rear side of the carrier 11, the driving assembly is fixedly connected with a straightening pneumatic clamp 41 through horizontal and longitudinal threads, and two clamping jaws of the straightening pneumatic clamp 41 can move in an opening and closing direction. The driving component drives the straightening pneumatic clamp 41 to longitudinally reciprocate towards one side of the wire feeding mechanism 2.

Specifically, two plate-shaped straightening arms 42 are horizontally and correspondingly connected to two vertically and vertically opened and closed clamping jaws of the straightening pneumatic clamp 41, and two straightening plates 43 which are driven by the straightening pneumatic clamp 41 to transversely clamp or release two-wire feet at the end of a double-core wire in the horizontal direction are fixedly connected to the front edge positions corresponding to the two straightening arms 42 through vertical and transverse threads.

Furthermore, in order to adapt to clamping double-core wires with different thicknesses and prevent the two straightening plates 43 from being excessively clamped to cause damage to the insulating sheath of the cable or the cable from being pinched off, the two straightening arms 42 are correspondingly provided with limiting rod assemblies for limiting the clamping degree of the two straightening plates 43.

Specifically, the limiting rod assembly is composed of an upper limiting rod 44 vertically and fixedly arranged on an upper straightening arm 42 and a lower limiting rod 45 vertically and fixedly arranged on a lower straightening arm 42 and abutted against the end of the upper limiting rod 44, the heights of the upper limiting rod 44 and the lower limiting rod 45 can be adjusted in a spiral mode, the folding degree of two clamping jaws of the straightening pneumatic clamp 41 is limited by the upper limiting rod 44 and the lower limiting rod 45, and therefore two straight plates 43 can clamp two-wire feet of double-core wires with proper force and distance.
