Description

Technical Field

[0001] The present invention relates to the technical field of wire harness terminal machines, and more specifically to a full-automatic wire harness double-end terminal machine. Background Art

[0002] In modern manufacturing, wire harnesses, as an important component of connecting electrical and electronic equipment, are widely used in many fields such as automobiles, home appliances, and communication equipment. Therefore, efficient wire harness processing equipment has become an indispensable part of the production line. Among them, wire harness double-head terminal machines, as a highly automated equipment, are widely used in the processing of wire harnesses to improve production efficiency and product quality.

[0003] The wire harness double-end terminal machine in the prior art mainly includes core mechanisms such as a feeding device, a cutting device, a stripping device, and a terminal crimping device. During the working process, the configured sensors and control systems can be used to realize full-process automation from wire feeding to finished product packaging. As the popularity of wire harness terminal machines in different fields increases, there are also devices on the market that can perform corresponding crimping through multiple sets of switchable tools to crimp wires of different materials, further improving the practicality of the wire harness terminal machine.

[0022] Through the knife-out mechanism configured on the wire stripping mechanism, the servo drive of the fifth servo motor can not only switch different stripping knives according to the characteristics of different layered materials of the wire, but also extend the perforation positioning needle through the third electric telescopic rod before the arc cavity plate is inserted into the stripping position at both ends of the wire harness, and align the guide wire layer with a smaller insertion end to ensure the smoothness of the insertion of the arc cavity plate, while improving the efficiency of the arc cavity plate in separating the protective layers at both ends of the wire harness in a point-to-surface manner.

[0023] By configuring the knife clamping mechanism on both sides of each knife-discharging mechanism, not only can the third cavity sleeve plate be controlled to be synchronously everted and retracted through the pulling action of the double-sided tooth plate, so that the stripping knife can be pressed by the second electric crawler on both sides in the retracted state, thereby improving the protection performance and service life of its knife head, but also the stripping knife can be polished by the configured sandpaper coating under the reciprocating drive of the second electric crawler, thereby ensuring the sharpness of the knife every time it is discharged and improving the smoothness of stripping.

At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are listed as the best and preferred embodiments, and other alternatives can also be used by technicians in some known technical fields; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0048] like Figures 1 to 12 As shown, an embodiment of the present invention provides a fully automatic wire harness double-end terminal machine, comprising a base bracket 1 and a wire harness placement base 2 fixedly installed at the axial position of the base bracket 1, a wire harness fastening module 3 is arranged at the middle position of the upper surface of the wire harness placement base 2, a wire harness taking module 4 for replenishing the wire harness to the wire harness fastening module 3 is arranged at the side position of the upper surface of the base bracket 1, and an outward expansion lifting mechanism 5 is arranged at the position on both sides of the wire harness fastening module 3 on the wire harness placement base 2; and a wire harness stripping mechanism 10 is arranged on the outward expansion lifting mechanism 5 on each side;

[0049] The outward-expanding lifting mechanism 5 includes a human-shaped bracket 53 that can be tightened in the center, a first electric telescopic rod 55 is fixedly installed on one side of the long side of the human-shaped bracket 53, and a circular partition 58 that can be turned outward is arranged on the output end of the first electric telescopic rod 55. The wire harness stripping mechanism 10 includes a second electric telescopic rod 513 arranged at the outer position of the bottom of the circular partition 58, and a first cavity sleeve plate 101 is arranged on the output end of the second electric telescopic rod 513. The knife mechanism 11 and the arc cavity plate 107 are arranged at symmetrical positions on both sides of the first cavity sleeve plate 101;

[0051] In order to solve the problem that the internal conductor wire is easily damaged due to excessive peeling when the fully automatic wire harness double-end terminal machine in the technology is stripping and crimping, the problem is solved by adopting the above-mentioned technical solution, which is mainly composed of a base bracket 1, a wire harness placement base 2, a wire harness fastening module 3, a wire harness picking module 4, an outward expansion lifting mechanism 5, a wire harness stripping mechanism 10 and a knife mechanism 11. The base bracket 1 serves as the base of the device and plays a supporting role, and the bottom of the base can be configured with a shock-absorbing base block for improving the overall stability to ensure the stability of the upper surface of the device during operation. The wire harness placement base 2 serves as a platform for placing the wire harness, and is used to cooperate with the wire harness picking module 4 to place the taken wire harness to be processed on a plane to perform the wire harness double-end terminal crimping work;

[0052] Among them, the outward-expanding lifting mechanism 5 is composed of a human-shaped bracket 53 and a circular partition 58 that are symmetrical on both sides. The human-shaped bracket 53 is a herringbone structure as a whole, with one side long and the other side short. It is arranged on both sides of the harness placement base 2 in a symmetrical arrangement, and can be tightened in the center, so that the harness placed on the harness placement base 2 can be centered before operation, ensuring the accuracy of insertion of each structure during subsequent operations, and the circular partition 58 can be rotated. When it is fully turned, it does not have the effect of tightening in the center. At this time, the knife mechanism 11 on both sides can be retracted, and the stripping knife 117 configured by the knife mechanism 11 can be stripped according to needs, and the bottom of the stripping knife 117 is configured with an arc cavity plate 107 that can be synchronously inserted into the two ends of the harness, so that the arc cavity plate 107 is padded between the guide wire and the stripping knife 117, and the two rotate synchronously for cutting to avoid the problem of damage to the internal conductor wire due to excessive stripping.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the harness fastening module 3 includes a semicircular notch 31 opened at the middle position of the harness placement base 2, a semicircular airbag cover 32 is fixedly installed inside the semicircular notch 31, and reserved slots 33 are opened at both sides of the harness placement base 2. A first servo air supply unit 34 is fixedly installed in the reserved slot 33 on one side of the harness placement base 2; a first servo motor 36 is fixedly installed in the reserved slot 33 on the other side, and the air supply output end of the first servo air supply unit 34 is connected to the semicircular airbag cover 32. A gear plate 37 is fixedly installed on the output end of the first servo motor 36; and a gear sleeve support rod 35 is movably installed in a reserved slot 33 on one side of the gear plate 37, and the gear of the gear sleeve support rod 35 is meshed with the gear plate 37. The reserved slots 33 on both sides of the wiring harness placement base 2 are the left and right sides of the wiring harness placement base 2, and the gear sleeve support rod 35 movably installed in the reserved slots 33 extends toward the front and rear sides of the wiring harness placement base 2, and a threaded rod 38 is fixedly connected to the protruding end on each side.

[0054] Among them, the configured semicircular airbag sleeve 32 is an inflatable airbag in the prior art, and its cross-sectional surface is semicircular. After inflation, it can be wrapped around the wiring harness placed on the inside to ensure the stability of the wiring harness, and the connected first servo air supply unit 34 is a device in the prior art that can accurately supply and exhaust air. A gear sleeve is configured on the rod surface of the gear sleeve support rod 35 movably installed in the reserved slot 33, and its gear sleeve is meshed and rotated with the gear plate 37 on the output end of the first servo motor 36. Under the rotation action of the gear plate 37, the gear sleeve support rod 35 can be driven to rotate, thereby causing the threaded rods 38 on both sides of the gear sleeve support rod 35 to rotate. The threaded openings of the threaded rods 38 configured on both sides of the gear sleeve support rod 35 are opposite, so that the meshed humanoid bracket 53 can be synchronously unfolded and retracted.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.11As shown, the outward-expanding lifting mechanism 5 includes a limiting rod 54 fixedly connected to the side positions of the front and rear surfaces of the wiring harness placement base 2; and a human-shaped bracket 53 corresponding to the threaded rod 38 on the same side is slidably mounted on the limiting rod 54 on each side, and an arc patch 51 is fixedly mounted at the position of the semicircular notch 31 on the front and rear sides of the wiring harness placement base 2, and a telescopic arc cloth cover 52 is fixedly mounted on the outer surface of the arc patch 51, and the telescopic arc cloth cover 52 is away from the arc patch 51. One side is fixedly connected to the humanoid bracket 53 on the same side, the wiring harness picking module 4 includes a multi-axis manipulator 41 fixedly installed on the side of the wiring harness placement base 2, and a clamping plate 42 is fixedly connected to the output end of the multi-axis manipulator 41, and the clamping plate 42 is semicircular in shape as a whole; and a second servo air supply unit 43 is fixedly installed at the upper side of the clamping plate 42, and a plurality of air holes 44 connected to the output end of the second servo air supply unit 43 are sequentially opened on the inner arc surface of the clamping plate 42.

[0056] Among them, the positions of the humanoid brackets 53 configured on both sides of the wire harness placement base 2 are symmetrical to each other to ensure the synchronization of subsequent deployment and retraction, and the telescopic arc cloth cover 52 connected between the arc patch 51 and the humanoid bracket 53 on each side is a cloth with a certain toughness in the prior art, which can be deployed and retracted following the deployment of the humanoid bracket 53. The configured multi-axis manipulator 41 is also a multi-axis servo mobile manipulator structure in the prior art, which can clamp the wire harness to the outer feeding end and place it in the semicircular airbag cover 32 of the wire harness placement base 2, and the structure of the second servo air supply unit 43 is the same as the first servo air supply unit 34, which is used to control the air holes 44 on the inner arc surface of the clamping plate 42 for adsorption, so that the clamping end is clamped more firmly.

[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a positioning spring buckle 510 is fixedly installed on the outer surface of the humanoid bracket 53 at a position aligned with the bottom of the semicircular notch 31, a circular fork frame 56 is fixedly connected to the output end of the first electric telescopic rod 55, and a reserved circular opening 511 corresponding to the positioning spring buckle 510 is opened on the surface of the circular fork frame 56, and a second servo motor 57 is fixedly installed at the outer edge of the circular fork frame 56, and a circular partition 58 is fixedly installed on the output end of the second servo motor 57, and the axis of the circular partition 58 is An infrared ranging unit 59 is fixedly installed at each position, and the ranging output end of the infrared ranging unit 59 faces the side of the semicircular notch 31. The side end of the ring fork frame 56 is fixedly connected with an extended bending rod 512 at the position on the side of the reserved circular opening 511. A second electric telescopic rod 513 is fixedly installed on the outer side of the extended bending rod 512. A push plate 514 is fixedly installed on the output end of the second electric telescopic rod 513. A third servo motor 515 is fixedly installed on the surface of the push plate 514 facing the side of the semicircular notch 31.

[0058] The circular fork frame 56 is a C-shaped structure as a whole, and the second servo motor 57 disposed on one side thereof is used to control the circular partition 58 to rotate. When the circular partition 58 is rotated outward, the circular fork frame 56 is C-shaped, and when the circular partition 58 is rotated inward, the circular partition 58 and the circular fork frame 56 form a disc, and under the action of the disc, the first electric telescopic rod 55 extends outward, and the disc formed by the disc can be extended to the two side ends of the semicircular airbag cover 32 to tighten the harness in the center. When the circular fork frame 56 extends outward and the reserved circular opening 511 fits with the positioning spring buckle 510, the center of the circular disk formed by the humanoid bracket 53 is aligned with the center of the semicircular notch 31, and the configured infrared ranging unit 59 is also a device for infrared ranging in the prior art. Under the action of its infrared ranging, when the formed circular disk is tightened toward the middle, the infrared ranging on both sides detects that the two ends of the wiring harness are close to the formed circular disk, that is, the circular partition 58, the centering movement of the humanoid bracket 53 can be stopped to prevent the inner wiring harness from being further tightened and bent.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a plurality of groups of friction ridges are fixedly installed on the inner arc surface of the semicircular airbag cover 32, the output end axis of the third servo motor 515 is aligned with the center of the semicircular slot 31, and the first electric crawler 9 is fixedly installed on both sides of the wiring harness placement base 2 at the bottom of the outward unfolding lifting mechanism 5, and the auxiliary bracket 7 is fixedly installed on both sides of the wiring harness placement base 2 at the position directly above the semicircular slot 31, and the upper side of the auxiliary bracket 7 is fixedly installed with a wiring harness terminal crimping unit 8, and the side of the wiring harness terminal crimping unit 8 is fixedly installed with a wiring harness terminal feeding unit 6.

[0060] Among them, several groups of friction ridges arranged on the inner arc surface of the semicircular airbag cover 32 can increase the clamping force of the clamping end. The wire harness terminal crimping unit 8 installed on both sides of the wire harness placement base 2 through the auxiliary bracket 7 is a conventional terminal crimping device in the prior art, which is used to perform terminal crimping on both sides of the aligned wire harness, and the configured wire harness terminal feeding unit 6 is a structure in the prior art for providing the wire harness terminal crimping unit 8 with a crimping terminal head. The configured first electric crawler 9 is used to transfer the peeled wire harness outer skin debris in real time during the working process.

[0061] The specific working process of the configured outward unfolding lifting mechanism 5 is as follows:

[0062] First, the clamping plate 42 at the output end is controlled by the multi-axis manipulator 41 to clamp the processed wire harness on the outside, and the second servo air supply unit 43 is used to evacuate air during the clamping process, so that the air hole 44 has adsorption properties, and after clamping, it is placed on the semicircular airbag cover 32 of the semicircular notch 31;

[0063] Then, the gear plate 37 at the output end of the first servo motor 36 is used to rotate the gear sleeve support rod 35 on the outside, so that the threaded rods 38 on both sides are rotated. During the rotation of the threaded rods 38, the human-shaped brackets 53 on both sides are retracted toward the semicircular airbag cover 32 along the limit rods 54. Before retracting, the circular fork frame 56 at the output end is extended outward by the first electric telescopic rod 55 until the reserved circular opening 511 of the circular fork frame 56 is stuck on the positioning spring buckle 510 on the human-shaped bracket 53. The circular partition 58 is rotated back by the second servo motor 57, and the infrared ranging units 59 on both sides use the rotated circular partition 58 to center the wiring harness placed on the semicircular airbag cover 32.

[0064] Then, the multi-axis manipulator 41 controls the clamping plate 42 to press the wire harness from top to bottom, and the second servo motor 57 drives the circular partition 58 to rotate outward, opening the circular fork frames 56 at both ends for the knife-out mechanism 11 to carry out the knife.

[0065] like Figure 4 , Figure 5 , Figure 6, Figure 7 As shown, the wire stripping mechanism 10 includes a first cavity sleeve 101 fixedly mounted on the output end of the third servo motor 515, and both sides of the first cavity sleeve 101 are provided with a slide groove guide rail 102; and a fourth servo motor 103 is fixedly mounted at the position of one side end of the slide groove guide rail 102, and the output end of the fourth servo motor 103 is fixedly mounted with a bidirectional threaded rod 104 extending in the slide groove guide rail 102, and the slide groove guide rails 102 on both sides of the first cavity sleeve 101 are slidably mounted with nut sleeves 105 corresponding to the bidirectional threaded rod 104 meshing; and the nut sleeves 105 on each side A second cavity sleeve plate 106 extending toward one side of the semicircular notch 31 is fixedly installed on the outer surface of the second cavity sleeve plate 106, and an arc cavity plate 107 is fixedly installed at the position where the outer side of the second cavity sleeve plate 106 extends toward one side of the semicircular notch 31. The arc cavity plate 107 is communicated with the internal cavity of the second cavity sleeve plate 106, and a third electric telescopic rod 108 is fixedly installed in the second cavity sleeve plate 106, and a perforation positioning needle 109 is fixedly installed on the output end of the third electric telescopic rod 108, and a circular opening for the perforation positioning needle 109 to pass through is opened at the axial center position of the side surface of the arc cavity plate 107.

[0066] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a lifting bracket 1010 is fixedly installed on the outer surface of the first cavity sleeve plate 101, and the knife-discharging mechanism 11 includes a fifth servo motor 111 fixedly installed on the surface of the lifting bracket 1010, and a disc sleeve plate 112 is fixedly installed on the output end of the fifth servo motor 111, and three groups of lateral cavity boxes 113 with the same intervals are clamped and installed on the outer edge surface of the disc sleeve plate 112; and a fourth electric telescopic rod 114 is fixedly installed inside each lateral cavity box 113, and a double-sided tooth plate 115 is fixedly installed on the output end of the fourth electric telescopic rod 114, and a bolt sleeve 116 is fixedly installed on the outer side of the double-sided tooth plate 115, and different types of skinning knives 117 are assembled in the three groups of lateral cavity boxes 113 arranged on the outer side of the disc sleeve plate 112 through the bolt sleeve 116.

[0067] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9As shown, gear columns 118 are movably installed at the positions of the two side edges of the bilateral tooth plate 115 in the lateral cavity box 113; and they are all meshed with the gear columns 118, and the outer side of the gear columns 118 is configured with a knife clamping mechanism 12, and the knife clamping mechanism 12 includes a third cavity sleeve 121, and the third cavity sleeve 121 has two groups of upper and lower guide grooves 122 on the surface of one side facing the skinning knife 117, and multiple first return spring rods 123 are fixedly installed in sequence inside the guide grooves 122, and the outer sides of the upper and lower groups of guide grooves 122 of the third cavity sleeve 121 are fixedly installed with second electric crawlers 124 through the first return spring rods 123.

[0068] Among them, the movable gear columns 118 are arranged on both sides of the double-sided tooth plate 115. When the double-sided tooth plate 115 is fully retracted, the bolt sleeves 116 on both sides will drive the third cavity sleeve 121 to be fully retracted. When the double-sided tooth plate 115 is fully extended outward, the gear columns 118 on both sides will also rotate in the opposite direction, so that the third cavity sleeve 121 on both sides is extended outward without interfering with the cutting work of the skinning knife 117 when it is extended.

[0069] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, a sandpaper sleeve is mounted on the outer surface of the second electric crawler 124, and a protective cover 125 is fixedly installed on the surface of the third cavity sleeve plate 121 at the outer sides of the upper and lower guide grooves 122, and an outward-flip door panel 126 is movably installed on the outer side of the protective cover 125.

[0070] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, a plurality of second return spring rods 127 are fixedly installed inside the protective cover 125, and the return extension ends of the second return spring rods 127 are all facing the second electric crawler 124 on the same side; and the extension ends are fixedly installed with ball sleeves 128, and the balls of the ball sleeves 128 are movably fitted on the surface of the second electric crawler 124 on the same side under the return extension action of the second return spring rods 127.

[0071] The specific working process of the configured knife-discharging mechanism 11 is as follows:

[0072] First, after the outward unfolding lifting mechanism 5 is retracted and the wiring harness on the semicircular airbag cover 32 is centered, the second electric telescopic rod 513 is retracted to control one side of the third servo motor 515 to be close to the two sides of the semicircular airbag cover 32. When the arc cavity plates 107 on both sides are attached to the two ends of the wiring harness, the bidirectional threaded rod 104 at its output end is controlled by the fourth servo motor 103 to rotate, so that the nut sleeve plates 105 symmetrically meshed on both sides of the bidirectional threaded rod 104 are moved, so that the sensors in the circular openings reserved on the surface of the outer arc cavity plate 107 are aligned with the two ends of the wiring harness for scanning. When the layered openings at the two ends of the wiring harness are scanned, the third electric telescopic rod 108 in the second cavity sleeve plate 106 is extended outward to push out the perforation positioning pin 109 at the output end of the third electric telescopic rod 108, so that the perforation positioning pin 109 is inserted into the layered opening;

[0073] Then, by further retracting the second electric telescopic rod 513, the arc cavity plate 107 is inserted into the layered opening along the insertion direction of the perforation positioning needle 109, so that the arc cavity plate 107 covers the inner upper layer of the layered opening and is cushioned on the upper side of the guide wire layer of the layer, so that the arc cavity plate 107 and the stripping knife 117 of the knife discharge mechanism 11 are located in a line, and the stripping knife 117 can be pushed outward by the fourth electric telescopic rod 114, inserted into the outer layer of the wire harness, and further inserted into the inside until it fits with the inner arc cavity plate 107. At this time, the stripping knives 117 inserted on both sides can be controlled to rotate and strip by the driving action of the third servo motor 515;

[0074] Among them, the third cavity sleeve 121 configured in the lateral cavity box 113 can control the second electric crawler 124 to rotate when the peeling knife 117 is retracted, so that the sandpaper on the outside of the second electric crawler 124 can grind the internal peeling knife 117. During the grinding process, in order to ensure the fit between the grinding end and the peeling knife 117 and to adapt to the thickness of different peeling knives 117, the second electric crawler 124 located on the upper and lower sides of the peeling knife 117 is connected to the reset end of the first reset spring rod 123. Under the reset action of the spring rod 123, the second electric crawlers 124 on both sides are guaranteed to be movable, and under the extrusion action of the second reset spring rod 127 inside the protective cover 125, the second electric crawlers 124 on both sides are fitted on the blades of the peeling knife 117, so that the grinding is more fitted, and the protective cover 125 can be opened through the outward-opening door plate 126, so that the sandpaper sleeve on the inner side of the second electric crawler 124 can be replaced, and the ball sleeve 128 is provided to ensure that the fitting end can also have movable performance under the extrusion state;

[0075] The multiple groups of lateral cavity boxes 113 arranged on the outside of the disc sleeve plate 112 are snap-fitted and can be disassembled and assembled, and different stripping knives 117 can be assembled on each side of the lateral cavity box 113 through the bolt sleeve 116 to adapt to the cutting of different materials. The installed perforation positioning needles 109 and the arc cavity plate 107 are both high-strength materials in the prior art, and the arc cavity plate 107 is a thin cavity structure as a whole. The thin shape is set to be smoothly inserted into the wiring harness, and the perforation positioning needle 109 inside is convenient for extension and retraction. The head of the perforation positioning needle 109 is equipped with a corresponding infrared scanning structure, which has the same structure as the infrared ranging unit 59, and is used to scan the layered gaps of the wiring harness to facilitate the insertion of the perforation positioning needle 109 into the gap.
