Description

Technical Field

[0001] The invention relates to the field of electric power engineering, and in particular to a wire stripping device and method for wire harness processing. Background Art

[0002] In power engineering, a wiring harness is usually composed of multiple cables, that is, an insulating sleeve is first wrapped around the outside of the cable core to form a cable, and then multiple cables are gathered together, and then the insulating sleeves are wrapped around the multiple cables to form a wiring harness. When recycling some waste wiring harnesses, the wiring harnesses need to be stripped first. The existing wiring harness stripping method first strips the outer insulating sleeve of the wiring harness, and then strips the insulating sleeve on the internal cable;

[0003] For example, the invention patent with application number CN201911209161.0 discloses a stripping device for electric wires and a stripping method thereof, including a frame, a control panel, a first clamping mechanism, a displacement mechanism, a stripping mechanism, a second clamping mechanism and a third clamping mechanism. The displacement mechanism is installed in the middle of the frame, the second clamping mechanism is installed on the displacement mechanism, the stripping mechanism is arranged on the left side of the second clamping mechanism, the first clamping mechanism is arranged on the left side of the stripping mechanism, the third clamping mechanism is arranged on the right side of the second clamping mechanism, and a control panel is installed on the upper part of the frame, the control panel is connected to the input end of the PLC controller, and the output end of the PLC controller is connected to the mechanical components of the device;

[0004] When the above patent structure is used, it mainly solves the problem that the stripping efficiency of the wire is low and the blade is easily damaged during the stripping process. However, the above patent structure directly strips the wire by a cutting knife. First, when stripping the wire, only the wire harness insulation cover or the cable insulation cover can be stripped separately. After the wire harness insulation cover is stripped, the cable insulation cover needs to be stripped on another device, which is inconvenient to strip the wire harness and the cables inside it in an integrated manner, thereby reducing the efficiency of wire harness stripping. Second, when stripping the wire harness insulation cover, most of the time, the insulation cover is directly cut open by a cutting knife, which can easily cut the cable insulation cover, causing damage to the wire harness, thereby reducing the processing quality of the wire harness stripping.

[0020] A method for using a wire stripping device for wire harness processing comprises the following steps:

[0021] The first step is to insert the wire body into the chassis and into the outer conveyor disc and the inner conveyor disc at the upper and lower positions. At the same time, according to the diameter of the wire body, the outer conveyor disc can be driven to move by the outer screw, and the inner conveyor disc can be driven to move by the inner screw, so the distance between the outer conveyor disc and the inner conveyor disc can be adjusted, the wire body can be squeezed, and a gap is left between the outer conveyor disc and the inner conveyor disc, and the upper and lower sides of the surface of the wire harness skin are squeezed to form a raised strip. At the same time, the first motor can drive the upper and lower sets of gear discs to engage and flip, so the gear disc can drive the outer conveyor disc and the inner conveyor disc to rotate through the spline cross shaft. When the outer conveyor disc and the inner conveyor disc are close to each other, the wire body can be intermittently conveyed to the right, and raised strips can be squeezed on the upper and lower sides of the surface of the wire body so that the subsequent wire harness stripping knife can cut the wire harness skin into two from the raised strip.

[0022] In the second step, when the toothed disc rotates, the belt can drive the long pin to rotate, and then the long pin can drive the preheating roller to rotate, so that the preheating roller can transport the wire harness skin to the right, and at the same time, the hot air blower can be started to transport hot air to the inside of the preheating roller, and discharged from the air outlet inside the concave ring groove of the preheating roller. Therefore, the raised strips can be preheated and softened through the upper and lower sets of preheating rollers, and at the same time, the cylinder can be started to drive the blower to move and make the air outlet pipe close to the raised strip, and then the blower is started to quickly blow air through the air outlet pipe to cool and shape the raised strip after the preheating and softening treatment, so that the raised strip can be shaped, so that the wire harness stripping knife can avoid scratching the cable core when cutting and stripping the wire harness skin, thereby protecting the cable core.

[0023] In the third step, the cylinder can drive the wire harness stripping knife to move to the shaped wire harness skin. At this time, the upper and lower groups of olive rollers are in contact, and when the wire harness skin moves to the right, the wire harness skin can be divided into two parts from the left and right directions of the raised strip by the wire harness stripping knife. At this time, the olive roller is located at the rear side of the wire harness skin and can guide the wire harness skin to both sides and unfold it. Then, one end of the stripped wire harness skin is fixedly connected to the winding disk. The second motor can make the spline longitudinal shaft drive the winding disk to rotate, and the stripped wire harness skin is wound up, thereby completing the stripping of the wire harness skin.

[0024] The fourth step is to adjust the distance between the two sets of cable core stripping knives according to the thickness of the cable core skin after stripping the wire harness skin, and then pass the exposed cable core skin through the through hole. When the cable core skin moves to the right, because the cable core stripping knife is triangular in shape, the cable core skin can be divided into two along its radial direction for stripping by two sets of cable core stripping knives. The stripped cable core skin is spread outward and separated from the cable core. At the same time, the third motor can drive the transmission cylinder to rotate through the belt, and then the transmission cylinder can drive the sun gear ring to rotate, and the sun gear ring can drive the planetary gear ring to rotate, so the sun gear ring and the planetary gear ring can drive the cutting knife on each side to rotate, so the cable core skin can be cut into a ring by the cutting knife to form a cable core skin segment, and as the cable core skin segment moves out of the through hole, it can fall off the cable core by itself, thereby completing the stripping of the cable core skin.

[0025] (III) Beneficial effects

[0026] The present invention provides a wire stripping device and method for wire harness processing, which has the following beneficial effects:

[0027] 1. The wire stripping device and method for wire harness processing can drive the outer conveying disk to move forward and backward by rotating the outer screw, and can drive the inner conveying disk to move forward and backward by rotating the inner screw. The spacing between the outer conveying disk and the inner conveying disk can be adjusted, and when the outer conveying disk and the inner conveying disk are close to each other, the wire body can be squeezed, and the upper and lower sides of the surface of the wire harness skin can be squeezed to form raised strips. At the same time, the cable core can be squeezed inward and gathered together, so that a gap is generated between the wire harness skin and the cable core and separated, so that the wire harness stripping knife can strip the wire harness skin.

[0028] 2. The wire stripping device and method for wire harness processing can preheat and soften the raised strips through a preheating roller, and quickly cool and shape the preheated and softened raised strips through an air outlet duct. When the wire harness stripping knife divides the wire harness skin into two, it will not cut the cable core skin on the surface of the cable core. Then, one end of the wire harness skin is fixed to the winding drum. When the winding drum rotates, the stripped wire harness skin can be wound up, so the wire harness can be stripped.

[0029] 3. The wire stripping device and method for wire harness processing can adjust the distance between the two sets of cable core stripping knives by rotating the adjusting screw. When the cable core skin passes through the through hole and moves to the right, the position of the cable core stripping knife can be adjusted according to the thickness of the cable core skin to prevent the cable core stripping knife from scratching the cable core. In the process of the cable core skin moving to the right, the cable core skin can be divided into two by the two sets of cable core stripping knives, and the cable core skin can be cut into cable core skin segments by the cutting knife again, so the cable core can be stripped.

[0047] In this embodiment, the spline transverse axis 203 is fixedly connected to the non-center position of the toothed disk 202, and the end faces of the outer conveying disk 207 and the inner conveying disk 208 are provided with spline grooves, and the outer conveying disk 207 and the inner conveying disk 208 are axially slidably connected with the spline transverse axis 203 through the spline grooves.

[0048] For details, please refer to the attached manual. Figure 4As shown, after the wire body 6 is inserted into the chassis 1 and enters the outer conveying tray 207 and the inner conveying tray 208 at the upper and lower positions, the outer conveying tray 207 and the inner conveying tray 208 can be adjusted according to the different diameters of the wire body 6, that is, the outer conveying tray 207 can be driven to move in the front-to-back direction by rotating the outer screw 205, and the inner conveying tray 208 can be driven to move in the front-to-back direction by rotating the inner screw 206, so the distance between the outer conveying tray 207 and the inner conveying tray 208 can be adjusted. When the distance between the outer conveying tray 207 and the inner conveying tray 208 is reduced, When the outer conveying disk 207 and the inner conveying disk 208 are close to each other, the electric wire body 6 can be squeezed, and the upper and lower sides of the surface of the wire harness skin 601 can be squeezed to form a raised strip 604. At the same time, the outer conveying disk 207 and the inner conveying disk 208 can also squeeze the cable core 602 inward to gather them together, so that a gap is generated between the wire harness skin 601 and the cable core 602 and they are separated, so that the wire harness stripping knife 406 can avoid scratching the cable core 602 when stripping the wire harness skin 601.

[0049] In this embodiment, an air outlet duct is provided at the output end of the hot air blower 302, the preheating roller 303 is a hollow roller, and an air outlet hole is opened in the concave ring groove on the surface of the preheating roller 303, and the air outlet duct extends to the inside of the preheating roller 303 and is rotatably connected to the preheating roller 303. Two groups of preheating rollers 303 are provided and are located on the upper and lower sides of the electric wire body 6, and the long pin 304 is connected to the toothed disc 202 through a belt.

[0050] For details, please refer to the attached manual. Figure 1 As shown, when the toothed disc 202 rotates, the long pin 304 can drive the preheating roller 303 to rotate through the belt, and transport the wire body 6 to the right. When the outer conveying disc 207 and the inner conveying disc 208 squeeze the surface of the wire harness skin 601 to form a raised strip 604, the hot air blower 302 can transport hot air to the inside of the preheating roller 303, and the hot air is discharged from the air outlet inside the concave ring groove of the preheating roller 303. Therefore, the raised strip 604 can be preheated and softened first, and the preheated and softened raised strip 604 can be quickly cooled and shaped by the blower 407 and the air outlet pipe 408. At this time, the upper and lower sides of the surface of the wire harness skin 601 can be separated from the cable core 602 inside it, so that the wire harness stripping knife 406 can prevent the cable core skin 603 from being cut when stripping the raised strip 604 on the surface of the wire harness skin 601, thereby protecting the cable core skin 603.

[0051] In this embodiment, the upper end surface of the output shaft of the second motor 401 is provided with a spline groove for inserting the spline longitudinal shaft 402, and the upper end surface of the spline longitudinal shaft 402 is provided with a cylindrical groove for inserting the pin 404, and the pin 404 passes through the frame 101 and is slidably connected thereto.

[0052] For details, please refer to the attached manual. Figure 5As shown, the spline longitudinal axis 402 is first inserted into the top end of the output shaft of the second motor 401, and then the pin 404 is inserted into the top end of the spline longitudinal axis 402. At this time, the top end of the spline longitudinal axis 402 can be supported and rotated by the pin 404. When the second motor 401 drives the winding drum 403 to rotate through the spline longitudinal axis 402, the top end of the winding drum 403 can be prevented from swinging. After the wire harness stripping knife 406 divides the wire harness skin 601 into two, one end of the wire harness skin 601 is fixed to the winding drum 403.

[0059] A method for using a wire stripping device for wire harness processing comprises the following steps:

[0060] In the first step, the wire body 6 is inserted into the chassis 1 and into the outer conveying tray 207 and the inner conveying tray 208 at the upper and lower positions. At the same time, according to the diameter of the wire body 6, the outer conveying tray 207 can be driven to move by the outer screw 205, and the inner conveying tray 208 can be driven to move by the inner screw 206, so that the distance between the outer conveying tray 207 and the inner conveying tray 208 can be adjusted, the wire body 6 can be squeezed, and a gap is left between the outer conveying tray 207 and the inner conveying tray 208, and the surface of the harness skin 601 is The upper and lower sides are squeezed to form a raised strip 604, and at the same time, the first motor 201 can drive the upper and lower sets of toothed discs 202 to engage and flip, so that the toothed disc 202 can drive the outer conveying disc 207 and the inner conveying disc 208 to rotate through the spline cross shaft 203. When the outer conveying disc 207 and the inner conveying disc 208 are close to each other, the wire body 6 can be intermittently conveyed to the right, and the raised strips 604 are squeezed on the upper and lower sides of the surface of the wire body 6, so that the subsequent wire stripping knife 406 can cut the wire skin 601 into two parts from the raised strip 604.

[0061] In the second step, when the toothed disc 202 rotates, the long pin 304 can be driven to rotate through the belt, and then the long pin 304 can drive the preheating roller 303 to rotate, so that the preheating roller 303 can transport the wire harness skin 601 to the right, and at the same time, the hot air blower 302 can be started to transport hot air to the inside of the preheating roller 303, and the hot air is discharged from the air outlet inside the concave ring groove of the preheating roller 303. Therefore, the raised strip 604 can be preheated and softened through the upper and lower groups of preheating rollers 303, and at the same time, the cylinder 405 can be started to drive the blower 407 to move and make the air outlet pipe 408 close to the raised strip 604, and then the blower 407 is started to make it pass through the air outlet pipe 408 to quickly blow and cool the raised strip 604 after the preheating and softening treatment, so that the raised strip 604 can be shaped, so that the wire harness stripping knife 406 can avoid scratching the cable core 602 when cutting and stripping the wire harness skin 601, thereby protecting the cable core 602.

[0062] In the third step, the cylinder 405 can drive the wire harness stripping knife 406 to move to the shaped wire harness skin 601. At this time, the upper and lower groups of olive rollers 410 are in contact, and when the wire harness skin 601 moves to the right, the wire harness skin 601 can be divided into two parts in the left and right directions from the raised strip 604 by the wire harness stripping knife 406. At this time, the olive roller 410 is located on the rear side of the wire harness skin 601 and can guide the wire harness skin 601 to both sides and unfold it, and then one end of the stripped wire harness skin 601 is fixedly connected to the winding drum 403, and the second motor 401 can make the spline longitudinal shaft 402 drive the winding drum 403 to rotate, and the stripped wire harness skin 601 is wound up, thereby completing the stripping of the wire harness skin 601.

[0063] In the fourth step, after the harness sheath 601 is stripped, the distance between the two sets of cable core stripping knives 514 is adjusted according to the thickness of the cable core sheath 603, and then the exposed cable core sheath 603 is passed through the through hole 503. When the cable core sheath 603 moves to the right, because the cable core stripping knife 514 is triangular in shape, the cable core sheath 603 can be divided into two along its radial direction for stripping by the two sets of cable core stripping knives 514. The stripped cable core sheath 603 is spread outward and separated from the cable core 602. At the same time, the third motor 501 drives the belt The transmission cylinder 507 can be driven to rotate, and then the transmission cylinder 507 can drive the sun gear ring 505 to rotate, and the sun gear ring 505 can drive the planetary gear ring 506 to rotate, so the sun gear ring 505 and the planetary gear ring 506 can drive the cutting knife 508 on each side to rotate, so the cable core skin 603 can be cut into a ring shape by the cutting knife 508 to form a cable core skin segment 515, and as the cable core skin segment 515 moves out of the through hole 503, it can fall off the cable core 602 by itself, thereby completing the stripping of the cable core skin 603.

[0064] The working principle and use process of the present invention are as follows: after the electric wire body 6 is inserted into the inside of the chassis 1 and enters the outer conveying tray 207 and the inner conveying tray 208 at the upper and lower positions, the outer conveying tray 207 and the inner conveying tray 208 can be adjusted according to the different diameters of the electric wire body 6, that is, the outer conveying tray 207 can be driven to move in the front-back direction by rotating the outer screw 205, and the inner conveying tray 208 can be driven to move in the front-back direction by rotating the inner screw 206, so that the distance between the outer conveying tray 207 and the inner conveying tray 208 can be adjusted. When the distance between the outer conveying tray 207 and the inner conveying tray 208 is reduced, the electric wire body 6 with a smaller diameter can be conveyed, and vice versa, the electric wire body 6 with a larger diameter can be conveyed, and when the outer conveying tray 207 and the inner conveying tray When the toothed disc 202 is close to each other, the wire body 6 can be squeezed, and the upper and lower sides of the surface of the wire harness skin 601 can be squeezed to form a raised strip 604. At the same time, the outer conveying disc 207 and the inner conveying disc 208 can also squeeze the cable core 602 inward to gather it together, so that a gap is generated between the wire harness skin 601 and the cable core 602 and they are separated, so that the subsequent wire harness stripping knife 406 can cut the wire harness skin 601 into two from the raised strip 604. When the toothed disc 202 rotates, the long pin 304 can be driven to rotate through the belt, and then the long pin 304 can drive the preheating roller 303 to rotate, so that the preheating roller 303 can transport the wire harness skin 601 to the right. At the same time, starting the hot air blower 302 can transport hot air to the inside of the preheating roller 303, and discharge it from the air outlet inside the concave ring groove of the preheating roller 303. The raised strip 604 can be preheated and softened by the upper and lower groups of preheating rollers 303. At the same time, the air cylinder 405 can be started to drive the blower 407 to move and make the air outlet 408 close to the raised strip 604. The blower 407 is then started to blow air through the air outlet 408 to quickly cool and shape the raised strip 604 after the preheating and softening treatment, so that the raised strip 604 can be shaped so that the wire stripping knife 406 can avoid scratching the cable core 602 when cutting and stripping the wire harness skin 601, thereby protecting the cable core 602. The air cylinder 405 can drive the wire stripping knife 406 to move to the shaped wire harness skin 601. At this time, the upper and lower groups of olive rollers 410 are in contact, and when the wire harness skin 601 moves to the right, the wire stripping knife 410 is used to move the wire harness skin 601 to the right. 06 can divide the wire harness skin 601 into two parts in the left and right directions from the raised strip 604. At this time, the olive roller 410 is located at the rear side of the wire harness skin 601, which can guide the wire harness skin 601 to both sides and unfold it. Then, one end of the stripped wire harness skin 601 is fixedly connected to the winding disk 403. The second motor 401 can drive the spline longitudinal shaft 402 to rotate the winding disk 403, and wind up the stripped wire harness skin 601, thereby completing the stripping of the wire harness skin 601. In the process of the cable core skin 603 passing through the through hole 503 and moving to the right, the adjusting screw 512 can be rotated to drive the adjusting spline shaft 513 to move radially along the separation disk 502. Therefore, the adjusting spline shaft 513 can drive the cable core stripping knife 514 to move radially along the separation disk 502.The distance between the two sets of cable core stripping knives 514 can be adjusted. Therefore, when the cable core skin 603 passes through the through hole 503 and moves to the right, the position of the cable core stripping knife 514 can be adjusted according to the thickness of the cable core skin 603 to prevent the cable core stripping knife 514 from scratching the cable core 602. In the process of the cable core skin 603 moving to the right, the cable core skin 603 can be divided into two by the two sets of cable core stripping knives 514, and the cable core skin 603 can be cut into cable core skin segments 515 by the cutting knife 508 again. In the process of the cable core 602 moving to the right, the cable core skin segment 515 can be dropped, thereby completing the stripping of the cable core skin 603.
