Description

Technical Field

[0001] The invention relates to the technical field of wire harness processing, in particular to a fully automatic multi-wire harness row gluing device. Background Art

[0002] The existing technical process for gluing wires of different colors together side by side is roughly as follows: first, use a wire-unwinding device to unwind wires from wire reels of each color; then, these wires pass through the wire-management holes on the fixed plate and are neatly gathered side by side by a gathering device; then, the wire bundles gathered side by side are transported to a heating box for preheating treatment to soften the surface of the wires for subsequent bonding; after heating, the wires are conveyed to a gluing area for gluing, and glue is used to firmly glue wires of different colors side by side together; then, a fan is used to quickly air-dry the glue on the wires to ensure rapid solidification of the glue; finally, the glued wires are unloaded through a feeding device.

[0003] When gluing the wire harnesses that have been gathered side by side, it is necessary to limit the two sides of the side-by-side wire harnesses by limit blocks before gluing to prevent the side-by-side wire harnesses from shifting during gluing. However, in the prior art, the limit blocks are usually moved manually to the two sides of the side-by-side wire harnesses to limit them, and then the limit blocks are manually fixed, resulting in a low degree of automation. Summary of the invention

[0004] The object of the present invention is to provide a fully automatic multi-wire harness row gluing device, aiming to solve the problems mentioned in the background technology.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0096] The above solution of the present invention includes at least the following beneficial effects:

[0097] When the wire harness moves toward the side of the workbench close to the unloading end, the wire harness drives the guide sleeve to rotate under the action of friction, and the guide sleeve drives the second rotating shaft to rotate through the elastic telescopic sliding sleeve assembly, and the second rotating shaft drives the second gear to rotate, and the second gear drives the torsion spring to twist. At the same time, the rotation of the second rotating shaft drives the second bidirectional threaded rod to rotate through the third pulley assembly, and the second bidirectional threaded rod drives the two moving plates to move toward the wire harness. At this time, the movement of the moving plate drives the movement of the first spring, and the first spring drives the limit plate to move until the limit plate is against the wire harness to limit the wire harness to prevent the wire harness from deviating when the subsequent glue coating assembly and the glue dripping mechanism coat the wire harness with glue. At this time, the moving plate continues to move toward the wire harness. The limit plate presses against the wiring harness, and the movable plate continues to move to compress the first spring, shortening the distance between the movable plate and the limit plate, thereby driving the pneumatic drive component to operate, and the pneumatic drive component causes the elastic telescopic sleeve assembly to disengage from the guide sleeve, and the guide sleeve rotates freely, and the movement of the elastic telescopic sleeve assembly drives the elastic telescopic brake assembly to operate, and the elastic telescopic brake assembly limits the second gear to stop rotating, thereby stopping the second rotating shaft from rotating. Since the third pulley assembly is connected to the second rotating shaft and the second bidirectional threaded rod, the second bidirectional threaded rod stops rotating, and the movable plate stops moving, realizing intelligent limiting, preventing the wiring harness from deviating, and solving the problem that traditional equipment requires manual operation to adjust and fix the limit plate.

[0098] When the wire harness is glued, the wire harness detaches from the guide sleeve. At this time, the limit plate moves under the elastic action of the first spring, and the distance between the moving plate and the limit plate is restored, thereby resetting the pneumatic drive assembly. In the absence of the action of the pneumatic drive assembly, the elastic telescopic sliding sleeve assembly is reset by its own elastic force and reconnects the guide sleeve and the second rotating shaft. In the absence of the action of the elastic telescopic sliding sleeve assembly, the elastic telescopic brake assembly also moves away from the second gear by its own elastic force, losing the effect of the elastic telescopic brake assembly, and the second gear rotates in the opposite direction and resets under the action of the torsion spring. The second gear drives the second rotating shaft to rotate in the opposite direction. The rotation of the second rotating shaft drives the second bidirectional threaded rod to rotate in the opposite direction through the third pulley assembly. The second bidirectional threaded rod drives the moving plate to move and reset along the second bidirectional threaded rod to the side away from the wire harness. The movement of the moving plate drives the first spring to move, and the first spring drives the limit plate to move and reset, so as to facilitate the subsequent intelligent limiting of the new wire harness.

DETAILED DESCRIPTION

[0109] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0110] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a fully automatic multi-wire harness row gluing device, comprising:

[0111] Workbench 1;

[0112] The gluing component 2 is arranged below the workbench 1;

[0113] The glue dripping mechanism 3 is arranged above the workbench 1;

[0114] A guiding mechanism 4, provided with several groups, for guiding the wiring harness;

[0115] The guiding mechanism 4 comprises:

[0116] A guide sleeve 8 is rotatably disposed on the workbench 1 and is used for guiding the wire harness;

[0117] An elastic telescopic sliding sleeve assembly 16 is slidably disposed in the guide sleeve 8;

[0118] The second rotating shaft 7 is sleeved in the elastic telescopic sliding sleeve assembly 16 and is rotatably connected to the guide sleeve 8;

[0119] The third fixed plate 6 is fixedly connected to the workbench 1 and is rotatably connected to the second rotating shaft 7;

[0120] The movable plate 11 is slidably disposed at both ends of the guide sleeve 8;

[0121] A second bidirectional threaded rod 5 is arranged parallel to one side of the guide sleeve 8 and is rotatably connected to the workbench 1. The second bidirectional threaded rod 5 is threadedly connected to the moving plate 11.

[0122] A third pulley assembly 9, used to connect the second rotating shaft 7 and the second bidirectional threaded rod 5;

[0123] The limiting plate 12 is slidably disposed on the guide sleeve 8 and is located on a side of the movable plate 11 close to the wire harness;

[0124] A plurality of first springs 13 are provided, and both ends of the first springs 13 are fixedly connected to the moving plate 11 and the limiting plate 12 respectively;

[0125] The pneumatic driving assembly 14 is used to drive the elastic telescopic sliding sleeve assembly 16 to move when the distance between the moving plate 11 and the limiting plate 12 is shortened, so as to drive the elastic telescopic sliding sleeve assembly 16 to separate from the guide sleeve 8;

[0126] The second gear 15 is fixedly connected to the second rotating shaft 7;

[0127] The torsion spring 10 is sleeved on the second rotating shaft 7, and the two ends are fixedly connected to the second gear 15 and the third fixing plate 6 respectively;

[0128] The elastic telescopic brake assembly 17 is mounted on the third fixed plate 6, and its two ends are respectively opposite to the teeth of the second gear 15 and the elastic telescopic sliding sleeve assembly 16;

[0129] When the wire harness moves toward the side of the workbench 1 close to the unloading end, the wire harness drives the guide sleeve 8 to rotate under the action of friction, and the guide sleeve 8 drives the second rotating shaft 7 to rotate through the elastic telescopic sliding sleeve assembly 16;

[0130] When the limit plate 12 is against the wiring harness, the movable plate 11 continues to move and compresses the first spring 13, shortening the distance between the movable plate 11 and the limit plate 12, thereby driving the pneumatic drive component 14 to operate. The pneumatic drive component 14 causes the elastic telescopic sleeve component 16 to disengage from the guide sleeve 8, and the guide sleeve 8 rotates freely. The movement of the elastic telescopic sleeve component 16 drives the elastic telescopic brake component 17 to operate. The elastic telescopic brake component 17 limits the second gear 15 to stop it from rotating, thereby stopping the second rotating shaft 7 from rotating.

[0131] In an embodiment of the present invention, when the wiring harness moves toward the side of the workbench 1 close to the unloading end, the wiring harness drives the guide sleeve 8 to rotate under the action of friction force, and the guide sleeve 8 drives the second rotating shaft 7 to rotate through the elastic telescopic sliding sleeve assembly 16, and the second rotating shaft 7 drives the second gear 15 to rotate, and the second gear 15 drives the torsion spring 10 to twist. At the same time, the second rotating shaft 7 rotates and drives the second bidirectional threaded rod 5 to rotate through the third pulley assembly 9, and the second bidirectional threaded rod 5 drives the two moving plates 11 to move toward the wiring harness. At this time, the movement of the moving plate 11 drives the first spring 13 to move, and the first spring 13 drives the limiting plate 12 to move until the limiting plate 12 presses against the wiring harness to limit the wiring harness to prevent the wiring harness from being offset when the subsequent glue coating assembly 2 and the glue dripping mechanism 3 glue the wiring harness. At this time, the moving plate 11 continues to move toward the wiring harness. As the limit plate 12 presses against the wiring harness, the movable plate 11 continues to move and compresses the first spring 13, shortening the distance between the movable plate 11 and the limit plate 12, thereby driving the pneumatic drive assembly 14 to operate, and the pneumatic drive assembly 14 causes the elastic telescopic sleeve assembly 16 to disengage from the guide sleeve 8, and the guide sleeve 8 rotates freely, and the movement of the elastic telescopic sleeve assembly 16 drives the elastic telescopic brake assembly 17 to operate, and the elastic telescopic brake assembly 17 limits the second gear 15 to stop rotating, thereby stopping the second rotating shaft 7, and thus stopping the rotation of the second rotating shaft 7. As the third pulley assembly 9 is connected to the second rotating shaft 7 and the second bidirectional threaded rod 5, the second bidirectional threaded rod 5 stops rotating, and the movable plate 11 stops moving, realizing intelligent limiting and preventing the wiring harness from deviating, solving the problem that the traditional equipment needs manual operation to adjust and fix the limit plate 12.

[0132] When the wire harness is glued, it is separated from the guide sleeve 8. At this time, the limit plate 12 moves under the elastic action of the first spring 13, and the distance between the movable plate 11 and the limit plate 12 is restored, so that the pneumatic drive component 14 is reset. In the absence of the pneumatic drive component 14, the elastic telescopic sliding sleeve component 16 is reset by its own elastic force and reconnects the guide sleeve 8 and the second rotating shaft 7. In the absence of the elastic telescopic sliding sleeve component 16, the elastic telescopic brake component 17 is also moved by its own elastic force to separate from the second gear 15, and the function of the elastic telescopic brake component 17 is lost. The second gear 15 is reversely rotated and reset under the action of the torsion spring 10, and the second gear 15 drives the second rotating shaft 7 to rotate in the opposite direction. The rotation of the second rotating shaft 7 drives the second bidirectional threaded rod 5 to rotate in the opposite direction through the third pulley assembly 9. The second bidirectional threaded rod 5 drives the movable plate 11 to move and reset along the second bidirectional threaded rod 5 to the side away from the wire harness. The movement of the movable plate 11 drives the first spring 13 to move, and the first spring 13 drives the limit plate 12 to move and reset, so as to facilitate the subsequent intelligent limiting of the new wire harness.

[0133] It should be noted that the third pulley assembly 9 includes two third pulleys and a third belt, the two third pulleys are respectively mounted on the second rotating shaft 7 and the second bidirectional threaded rod 5, and the third belt is sleeved on the two third pulleys.

[0139] The two ends of the hose 142 are respectively connected to the cavities on the first piston cylinder and the second piston cylinder.

[0140] In the embodiment of the present invention, when the movable plate 11 moves and compresses the first spring 13, the movable plate 11 drives the first piston cylinder to move, so that the first piston rod and the first piston of the first piston cylinder assembly 141 push the gas in the first piston cylinder into the second piston cylinder of the second piston cylinder assembly 143 through the hose 142, thereby driving the second piston of the second piston cylinder assembly 143 to move toward the side away from the guide sleeve 8, the second piston drives the second piston rod to move, the second piston rod drives the pull plate 144 to move, and the pull plate 144 drives the elastic telescopic sliding sleeve assembly 16 to move toward the side away from the guide sleeve 8.

[0141] When the wiring harness detaches from the guide sleeve 8, the limit plate 12 moves under the elastic action of the first spring 13, the limit plate 12 drives the first piston rod to move, the first piston rod drives the first piston to move, so that the volume in the cavity of the first piston cylinder close to the elastic telescopic sliding sleeve assembly 16 increases, thereby generating suction and sucking the gas in the second piston cylinder into the first piston cylinder through the hose 142, thereby driving the second piston to move to the side close to the guide sleeve 8, the second piston drives the second piston rod to move, and the second piston rod drives the pull plate 144 to move and reset.

[0142] like Figure 4 As shown, as a preferred embodiment of the present invention, the elastic telescopic sleeve assembly 16 includes:

[0143] The fixing ring 161 is sleeved on the second rotating shaft 7 and fixedly connected to the second rotating shaft 7;

[0146] The embedding grooves 164 are provided on the second rotating shaft 7 at equal intervals around the circumference;

[0147] The spline 165 is slidably connected in the embedding groove 164 and fixedly connected to the movable ring 162 . The spline 165 is slidably connected to the spline groove at one end of the guide sleeve 8 .

[0148] In the embodiment of the present invention, when the guide sleeve 8 rotates, the guide sleeve 8 drives the spline 165 to rotate through the spline groove, the spline 165 drives the second rotating shaft 7 to rotate through the embedded groove 164, the second rotating shaft 7 drives the fixed ring 161 to rotate, the rotation of the spline 165 drives the movable ring 162 to rotate, and the fixed ring 161 and the movable ring 162 drive the second spring 163 to rotate.

[0149] When the pull plate 144 moves, the pull plate 144 drives the movable ring 162 to move to the side away from the guide sleeve 8 to compress the second spring 163, and the movable ring 162 drives the spline 165 to move along the embedding groove 164 to disengage from the spline groove of the guide sleeve 8. At this time, the rotation of the guide sleeve 8 will not drive the second rotating shaft 7 to rotate.

[0150] When the pull plate 144 moves to reset, the movable ring 162 moves to reset toward the side close to the guide sleeve 8 under the elastic action of the second spring 163 , and the movable ring 162 drives the spline 165 to move along the embedding groove 164 and insert into the spline groove of the guide sleeve 8 .

The third spring 174 is continuously moved and compressed, and at the same time, the support plate 171 drives the third sleeve 172 to move, so that the second slide cylinder 173 slides along the slide groove of the third sleeve 172 toward the side close to the support plate 171, until the tooth groove of the second gear 15 rotates to be opposite to the insert block 175. The insert block 175 moves toward the side close to the second gear 15 and is inserted into the tooth groove under the elastic action of the third spring 174. The insert block 175 drives the second slide cylinder 173 to slide along the slide groove of the third sleeve 172 toward the side close to the second gear 15, thereby limiting the second gear 15 and preventing the second shaft 7 and the second gear 15 from continuing to rotate due to inertia.

The second slide cylinder 173 and the third spring 174 drive the plug block 175 to move and disengage from the second gear 15. The second gear 15 rotates in the opposite direction under the action of the torsion spring 10. The second gear 15 drives the second rotating shaft 7 to rotate in the opposite direction. The second rotating shaft 7 drives the spline 165 to rotate through the embedded groove 164. The spline 165 drives the guide sleeve 8 to rotate in the opposite direction through the spline groove of the guide sleeve 8. At the same time, the second rotating shaft 7 rotates in the opposite direction and drives the second bidirectional threaded rod 5 to rotate in the opposite direction through the third pulley assembly 9.

[0219] The gear ring 332 is fixedly connected to the outer wall of the connecting cover 329 and meshingly connected to the first gear 324 .

[0220] In the embodiment of the present invention, when the first gear 324 rotates, the first gear 324 drives the ring gear 332 to rotate, the ring gear 332 drives the connecting cover 329 to rotate, the connecting cover 329 drives the limiting rod 328 to slide along the straight groove 326 through the limiting groove 331, the limiting rod 328 drives the baffle 327 to move, so that the baffle 327 is expanded, so that the glue of the glue outlet hose 37 drips out through the gap after the baffle 327 is expanded. The present invention can adjust the glue output amount by the expansion size of the baffle 327.

[0221] The above embodiment of the present invention provides a fully automatic multi-wire harness row gluing device, which achieves the following technical effects:

[0222] When the wire harness moves toward the side of the workbench 1 close to the unloading end, the wire harness drives the guide sleeve 8 to rotate under the action of friction force, the guide sleeve 8 drives the spline 165 to rotate through the spline groove, the spline 165 drives the second rotating shaft 7 to rotate through the embedded groove 164, the second rotating shaft 7 drives the fixed ring 161 to rotate, the rotation of the spline 165 drives the moving ring 162 to rotate, and the fixed ring 161 and the moving ring 162 drive the second spring 163 to rotate;

[0223] The rotation of the second rotating shaft 7 drives the second gear 15 to rotate, and the second gear 15 drives the torsion spring 10 to twist. At the same time, the rotation of the second rotating shaft 7 drives the second bidirectional threaded rod 5 to rotate through the third pulley assembly 9, and the second bidirectional threaded rod 5 drives the two moving plates 11 to move toward the wiring harness. At this time, the movement of the moving plate 11 drives the first spring 13 to move, and the first spring 13 drives the limiting plate 12 to move until the limiting plate 12 is against the wiring harness to limit the wiring harness to prevent the wiring harness from being offset when the subsequent glue coating assembly 2 and the glue dripping mechanism 3 glue the wiring harness. At this time, the moving plate 11 continues to move toward the wiring harness. As the limit plate 12 presses against the wiring harness, the movable plate 11 continues to move and compresses the first spring 13, shortening the distance between the movable plate 11 and the limit plate 12. The movement of the movable plate 11 drives the first piston cylinder to move, so that the first piston rod and the first piston of the first piston cylinder assembly 141 push the gas in the first piston cylinder into the second piston cylinder of the second piston cylinder assembly 143 through the hose 142, thereby driving the second piston of the second piston cylinder assembly 143 to move away from the guide sleeve 8, the second piston drives the second piston rod to move, and the second piston rod drives the pull plate 144 to move;

[0224] The movement of the pull plate 144 drives the moving ring 162 to move to the side away from the guide sleeve 8 to compress the second spring 163. The moving ring 162 drives the spline 165 to move along the embedding groove 164 to disengage from the spline groove of the guide sleeve 8. At this time, the guide sleeve 8 rotates freely. The movement of the moving ring 162 drives the abutment plate 171 to move. The abutment plate 171 drives the third sleeve 172, the second slide cylinder 173 and the third spring 174 to move. The second slide cylinder 173 and the third spring 174 drive the plug block 175 to move. If the tooth groove of the second gear 15 just rotates to be opposite to the plug block 175 at this time, the plug block 175 moves and is inserted into the tooth groove of the second gear 15. If the tooth groove of the second gear 15 does not rotate to be opposite to the plug block 175, Relatively speaking, at this time, the insert block 175 moves to abut against the second gear 15, and the push plate 171 continues to move to compress the third spring 174. At the same time, the push plate 171 drives the third sleeve 172 to move, so that the second slide cylinder 173 slides along the slide groove of the third sleeve 172 to the side close to the push plate 171, until the tooth groove of the second gear 15 rotates to be opposite to the insert block 175. Under the elastic action of the third spring 174, the insert block 175 moves to the side close to the second gear 15 and is inserted into the tooth groove. The insert block 175 drives the second slide cylinder 173 to slide along the slide groove of the third sleeve 172 to the side close to the second gear 15, so as to limit the second gear 15 and prevent the second shaft 7 and the second gear 15 from continuing to rotate due to inertia.

[0225] The second gear 15 stops rotating, and then the second rotating shaft 7 stops rotating. Since the third pulley assembly 9 is connected to the second rotating shaft 7 and the second bidirectional threaded rod 5, the second bidirectional threaded rod 5 stops rotating, and the moving plate 11 stops moving, so that intelligent limiting is realized to prevent the wire harness from deviating, and the problem that the traditional equipment needs manual operation to adjust and fix the limiting plate 12 is solved;

[0226] After the wire harness is coated with glue, the wire harness is separated from the guide sleeve 8. At this time, the limit plate 12 moves under the elastic action of the first spring 13. The movement of the limit plate 12 drives the first piston rod to move, and the first piston rod drives the first piston to move, so that the volume of the cavity of the first piston cylinder close to the elastic telescopic sliding sleeve assembly 16 increases, thereby generating suction and sucking the gas in the second piston cylinder into the first piston cylinder through the hose 142, thereby driving the second piston to move to the side close to the guide sleeve 8, the second piston drives the second piston rod to move, and the second piston rod drives the pull plate 144 to move and reset;

[0227] When the pull plate 144 moves to reset, the moving ring 162 moves to reset toward the side close to the guide sleeve 8 under the elastic action of the second spring 163, and the moving ring 162 drives the spline 165 to move along the embedding groove 164 and insert into the spline groove of the guide sleeve 8;

[0228] After the moving ring 162 moves and resets, the push plate 171 moves and resets to the side close to the guide sleeve 8 under the elastic action of the fourth spring 176, and the push plate 171 drives the third sleeve 172, the second slide cylinder 173 and the third spring 174 to move and reset, and the second slide cylinder 173 and the third spring 174 drive the plug block 175 to move and disengage from the second gear 15, and the second gear 15 rotates in the opposite direction under the action of the torsion spring 10, and the second gear 15 drives the second rotating shaft 7 to rotate in the opposite direction, and the second rotating shaft 7 drives the spline 165 to rotate through the embedded groove 164, and the spline 165 drives the guide sleeve 8 to rotate in the opposite direction through the spline groove of the guide sleeve 8. At the same time, the second rotating shaft 7 rotates in the opposite direction and drives the second bidirectional threaded rod 5 to rotate in the opposite direction through the third pulley assembly 9, and the second bidirectional threaded rod 5 drives the moving plate 11 to move and reset along the second bidirectional threaded rod 5 to the side away from the wiring harness, and the moving plate 11 moves and drives the first spring 13 to move and reset, and the first spring 13 drives the limiting plate 12 to move and reset, so as to facilitate the subsequent intelligent limiting of the new wiring harness;

[0229] When the movable plate 11 moves toward the wiring harness, the movable plate 11 drives the adjacent first sleeve 27, the second sleeve 212, the adjacent first sleeve 27, the first slide 213 and the adjacent first slide 213, the second sleeve 212 to move toward the wiring harness through the first connecting plate 211, the first slide 213 drives the second scraper 210 to move along the avoidance groove 28, the first sleeve 27 and the second sleeve 212 drive the first scraper 29 to move, and the length of the second scraper 210 and the first scraper 29 scraping glue is adjusted to adapt to different numbers of parallel wiring harnesses, the second scraper 210 and the first scraper 29 scrape the glue on the glue roller 23 without the wiring harness area, the scraped glue falls back into the glue storage box 22 under gravity reuse for collection, to prevent the glue from being separated from the glue storage box 22 as the glue roller 23 rotates, and is air-dried on the glue roller 23, resulting in glue waste;

[0230] When the movable plate 11 moves away from the wire harness, the movable plate 11 drives the adjacent first sleeve 27, the second sleeve 212, the adjacent first sleeve 27, the first slide 213 and the adjacent first slide 213, the second sleeve 212 to move away from the wire harness through the first connecting plate 211, the first slide 213 drives the second scraper 210 to move and reset along the avoidance groove 28, and the first sleeve 27 and the second sleeve 212 drive the first scraper 29 to move and reset, so as to prepare for the next scraping of glue;

[0231] When applying glue, the cylinder 34 drives the push plate 35 to move downward along the first bidirectional threaded rod 39 and the round rod 317 to disengage from the upper positioning plate 313. The first bidirectional threaded rod 39 moves downward and resets under the elastic action of the spring buffer 312. The first bidirectional threaded rod 39 drives the upper positioning plate 313 to move downward and reset along the round rod 317. At the same time, the first bidirectional threaded rod 39 drives the glue pushing piston 310 to move downward along the glue outlet pipe 37. The push plate 35 continues to move downward to resist the lower positioning plate 314 and drive the lower positioning plate 314 to move downward. The lower positioning plate 314 drives the first bidirectional threaded rod 39 to move downward to stretch the spring buffer 312. The first bidirectional threaded rod 39 drives the glue pushing piston 310 to move downward along the glue outlet pipe 37. The glue pushing piston 310 moves downward to squeeze out the glue in the glue outlet pipe 37 and drips it onto the wiring harness directly below it. The push plate 35 is driven to move upward along the first bidirectional threaded rod 39 and the round rod 317 to disengage from the lower positioning plate 314.
