Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.

[0039] Reference Figures 1 to 10, the X-axis, Y-axis, and Z-axis in the figure are mutually orthogonal axes. The X-axis and Y-axis are both parallel to the horizontal plane, and the Z-axis is parallel to the vertical direction.

[0043] The wire feeding assembly 100 and the wire pulling assembly 200 are arranged along the second direction.

[0044] Specifically, the wire feeding assembly 100 includes a wire cutting device 110 , a wire feeding frame driving member 120 , a wire feeding frame body 130 , a wire clamping assembly 140 and a near clamping driving member 150 .

[0045] The wire feeding assembly 100 is provided with a wire channel extending along the second direction and a wire switching direction. Specifically, in this embodiment, the wire switching direction is parallel to the vertical direction. In other embodiments, the wire switching direction can also be set to be parallel to the first direction.

[0046] The wire feeding frame 130 is slidably connected to the frame 001, and guide rails and slides are arranged between the wire feeding frame 130 and the frame 001. The number of guide rails and slides is set to two groups, and the two groups of guide rails and slides are respectively arranged at the two ends of the wire feeding frame 130 in the second direction. By arranging guide rails and slides between the wire feeding frame 130 and the frame 001, the wire feeding frame 130 can be guided to avoid tilting of the wire feeding frame 130 during movement.

[0047] The wire feeding frame 130 is provided with multiple wire guide assemblies, and the multiple wire guide assemblies are arranged along the wire switching direction, that is, in this embodiment, the multiple wire guide assemblies are arranged along the up and down directions, and each wire guide assembly guides different wires respectively, so that the wire pulling, cutting and stripping device can adapt to different wires (such as wires of different colors or thicknesses, etc.), thereby meeting customer needs.

[0048] Specifically, the wire guide assembly includes a plurality of wire guide cylinders 131 arranged along the second direction. The wire passes through the wire guide cylinders 131, which limit and guide the wire.

[0049] The wire feeding frame driving component 120 is configured as a linear driving device composed of a servo motor and a lead screw slide.

[0050] In other embodiments, the wire feed frame drive can be directly configured as an electric or hydraulic linear drive device. Even when only two wires need to be switched, a pneumatic linear drive device can be used. The wire feed frame drive member 120 drives the wire feed frame body 130 and the multiple wire guide assemblies mounted on the wire feed frame body 130 to move vertically up and down to switch the wires to be processed.

[0051] Two wire clamping assemblies 140 are provided, one on each side of the wire channel in the first direction. Approaching clamping drive members 150 are provided in a one-to-one correspondence with each wire clamping assembly 140. Approaching clamping drive members 150 are configured as linear cylinders. In other embodiments, approaching clamping drive members 150 may also be configured as other conventional linear drive devices, such as linear motors or linear hydraulic cylinders. Persons skilled in the art may select approaching clamping drive members 150 based on actual needs.

[0052] Specifically, the wire clamping and feeding assembly 140 includes a wire clamping and feeding frame 141 , a wire clamping and feeding driving member 142 , a wire clamping and feeding driving wheel 143 and a wire clamping and feeding belt 144 .

[0053] The wire clamping and feeding frame 141 is slidably connected to the frame 001, and the wire clamping and feeding frame 141 is fixedly connected to the output end close to the clamping and feeding driving member 150. The wire clamping and feeding frame 141 can move parallel to the first direction relative to the frame 001, and the clamping and feeding driving member 150 drives the wire clamping and feeding assembly 140 to approach or move away from the wire channel along the first direction.

[0054] The wire clamping and feeding drive member 142 and the wire clamping and feeding drive wheel 143 are both mounted on the wire clamping and feeding frame 141. The wire clamping and feeding drive member 142 is configured as a rotary motor, and the number of wire clamping and feeding drive wheels 143 is configured to be multiple. The multiple wire clamping and feeding drive wheels 143 are all rotatably connected to the wire clamping and feeding frame 141, and one of the wire clamping and feeding drive wheels 143 is fixedly connected to the output end of the wire clamping and feeding drive member 142. The wire clamping and feeding belt 144 passes around the multiple wire clamping and feeding drive wheels 143, and the wire clamping and feeding belt 144 is in driving connection with the wire clamping and feeding drive wheels 143.

[0055] The two wire clamping belts 144 provided on both sides of the wire channel are used to clamp the wires in the wire channel, and then the two wire clamping driving members 142 respectively drive the two wire clamping belts 144 to move, thereby realizing forward transportation of the wires.

[0056] When it is necessary to switch the wire to be used, the wire clamping drive 150 is first driven close to the wire clamping assembly 140 away from the wire channel, and then the wire feeding frame drive 120 drives the wire feeding frame body 130 to move in the wire switching direction, so that the wire guide assembly and the wire cutting device 110 where the wire to be used is located are arranged along the second direction, and then the wire clamping drive 150 is driven close to the wire channel to transport the wire forward, and then the subsequent operations on the wire are continued.

[0057] Specifically, in this embodiment, the wire feeding assembly 100 further includes a tension adjustment assembly 160 . The tension adjustment assembly 160 includes two tension wheel assemblies. The two tension wheel assemblies are respectively disposed on both sides of the wire channel in the first direction.

[0058] The tension wheel assembly includes a tension adjustment frame 161, a plurality of tension adjustment wheels 162, and a tension wheel movable driver 163. The tension wheel movable driver 163 is fixedly mounted on the frame 001 and is configured as a linear motor. In other embodiments, the tension wheel movable driver 163 can also be configured as other conventional linear drive devices. Those skilled in the art can select the tension wheel movable driver 163 according to actual needs.

[0059] The tension adjustment frame 161 is fixedly connected to the output end of the tension wheel moving driver 163 , and the tension wheel moving driver 163 drives the tension adjustment frame 161 to move closer to or away from the wire channel.

[0060] The plurality of tension adjustment wheels 162 are all mounted on the tension adjustment frame 161 and are rotatably connected to the tension adjustment frame 161 . The plurality of tension adjustment wheels 162 are arranged along the second direction.

[0061] When the tension wheel moving driving member 163 drives the tension adjustment frame 161 to approach or move away from the wire channel, it drives the plurality of tension adjustment wheels 162 to approach or move away from the wire channel at the same time.

[0062] Specifically, the tension adjustment wheels 162 of the two tension wheel assemblies are staggered, and the two tension wheel assemblies cooperate to adjust the tension of the wire.

[0063] The wire cutting device 110 includes a wire output sleeve 111 and two clamping and cutting devices arranged along a first direction. The wire output sleeve 111 is fixedly connected to the frame 001.

[0064] The clamping and cutting device is arranged on one side of the wire output sleeve 111 close to the wire feeding frame body 130. The clamping and cutting device includes a clamping and cutting driving member 112, a clamping and cutting block 113 and a clamping and cutting knife 114.

[0065] The clamping and cutting drive member 112 is fixedly installed on the frame 001. In this embodiment, the clamping and cutting drive member 112 is configured as a linear cylinder. In other embodiments, the clamping and cutting drive member 112 can also be configured as a conventional linear drive device such as a linear motor or a linear hydraulic cylinder. Those skilled in the art can select the specific structure of the clamping and cutting drive member 112 according to actual needs.

[0066] The clamping and cutting blade 114 is fixedly connected to the clamping and cutting block 113, and the clamping and cutting blade 114 is fixedly installed at one end of the clamping and cutting block 113 away from the wire feeding frame body 130. The clamping and cutting blade 114 is used to cut the wire for the first time so that the wire roughly meets the length required by the customer.

[0067] When cutting the wire, the two clamping and cutting driving members 112 respectively drive the two clamping and cutting blocks 113 and the two clamping and cutting knives 114 to approach each other, and then the two clamping and cutting knives 114 cut the wire, and the two clamping and cutting blocks 113 clamp the front end of the wire to prevent the wire from falling.

[0068] When the wire needs to be transported forward, the two clamping and cutting drive members 112 respectively drive the two clamping and cutting blocks 113 away from each other, and at the same time the wire clamping and feeding assembly 140 drives the wire forward. At this time, due to the short execution time, the front end of the wire will not move downward much, and the front end of the wire can be smoothly inserted into the wire output sleeve 111. In other embodiments, a supporting structure can also be provided to support the wire to avoid the front end of the wire from moving downward, thereby ensuring that the front end of the wire can be smoothly inserted into the wire output sleeve 111. Those skilled in the art can choose whether to add a supporting structure according to actual needs.

[0069] The wire feeding assembly 100 further includes two wire clamping assemblies, which are respectively disposed at two ends of the wire feeding assembly 100 in the second direction.

[0070] The wire clamping assembly includes a plurality of wire clamping devices and a wire clamping drive 171. The wire clamping devices are arranged in a one-to-one correspondence with the wire guide assembly. The wire clamping device includes a reset structure, a movable clamping block 172 and a fixed clamping block 173. The fixed clamping block 173 is fixedly connected to the wire feeding frame body 130. The fixed clamping block 173 is slidably connected to the movable clamping block 172, and the movable clamping block 172 slides parallel to the first direction relative to the fixed clamping block 173. The fixed clamping block 173 is provided with a first clamping surface, and the movable clamping block 172 is provided with a second clamping surface, and the second clamping surface and the first clamping surface are arranged opposite to each other. The reset structure is arranged between the fixed clamping block 173 and the movable clamping block 172, and the reset structure makes the first clamping surface and the second clamping surface always have a tendency to approach each other. The wire clamping drive 171 is fixedly mounted on the frame 001, and the wire clamping drive 171 is configured as a linear cylinder. In other embodiments, the wire clamping drive 171 can also be configured as other conventional linear drive devices such as a linear motor. The wire clamping driving member 171 is provided with a wire clamping output end, which is used to abut against the movable clamping block 172 and drive the movable clamping block 172 so that the second clamping surface is away from the first clamping surface.

[0071] When the wire in one of the wire guide assemblies needs to move forward, the wire clamping drive 171 works to drive the movable clamp 172 to move, so that the second clamping surface moves away from the first clamping surface, so that the wire is no longer clamped by the fixed clamp 173 and the movable clamp 172, so that the wire can be transported forward smoothly.

[0072] When switching the wire to be processed, the wire clamping drive 171 is reset, so that the fixed clamp 173 and the movable clamp 172 clamp the wire again, and then the wire feeding frame drive 120 drives the wire feeding frame body 130 to move in the wire switching direction, so that the wire guide assembly where the wire to be used is located and the wire cutting device 110 are arranged along the second direction. When the wire feeding frame body 130 moves into place, the wire clamping drive 171 works again, so that the wire is no longer clamped by the fixed clamp 173 and the movable clamp 172, so that the wire can be transported forward smoothly.

[0073] By setting up a wire clamping device, the wire can be clamped when the wire feeding frame 130 moves along the wire switching direction, thereby preventing the wire from accidentally loosening during the movement of the wire feeding frame 130 along the wire switching direction, thereby ensuring the normal progress of subsequent work.

[0074] The wire pulling assembly 200 includes a wire pulling swing driving member 210 and a wire pulling clamp 220 .

[0075] The wire pull swing drive 210 is fixedly mounted on the frame 001, and the wire pull swing drive 210 is arranged above the wire output sleeve 111. In this embodiment, the wire pull swing drive 210 is arranged as a swing cylinder. In other embodiments, the wire pull swing drive 210 can also be arranged as other conventional rotating drive devices such as a rotating motor.

[0076] The output end of the wire pulling swing drive 210 is fixedly mounted with a flip swing arm 230, and the wire pulling clamp 220 is fixedly mounted on the end of the flip swing arm 230 away from the wire pulling swing drive 210. The flip swing arm 230 can increase the swing radius of the wire pulling clamp 220. The wire pulling swing drive 210 drives the flip swing arm 230 and the wire pulling clamp 220 to swing 180 degrees around the swing axis (that is, the wire pulling clamp 220 swings 180 degrees around the vertical direction) so that the front end of the wire flips 180 degrees. Specifically, in the present embodiment, the wire pulling clamp 220 is configured as a pneumatic clamp. In other embodiments, the wire pulling clamp 220 can also be configured as an electric clamp.

[0077] When pulling the wire, the wire clamping claw 220 clamps the front end of the wire, and then the wire swing driving member 210 drives the wire clamping claw 220 to rotate, and at the same time the wire clamping assembly 140 transports the wire forward, so that the wire is sent out to the set length and is U-shaped.

[0078] By setting up the wire pulling assembly 200, the wire is U-shaped after being pulled out, and the end of the wire away from the wire pulling clamp 220 can droop, thereby effectively reducing the maximum length of the wire in the horizontal direction during transportation and processing. Compared with a linear wire pulling device, the area of ​​the factory occupied by the wire processing equipment can be greatly reduced to improve the utilization rate of the factory.

[0079] In other embodiments, the swing axis may also be set to be parallel to the second direction. Those skilled in the art may select the specific setting of the swing axis according to actual needs and adjust the specific structures of other components accordingly.

[0080] The cutting and peeling assembly 400 includes a cutting and peeling knife group 410 and a cutting and peeling drive structure 420. The number of the cutting and peeling knife groups 410 is set to two, and the two cutting and peeling knife groups 410 are arranged in the up and down direction.

[0081] The cutting and stripping knife assembly 410 includes a cutting knife and a stripping knife. The cutting knife is used to further trim the ends of the wire to meet customer length requirements. The stripping knife is used to create an incision in the wire insulation. The stripping knife cooperates with the disengagement mechanism 320, which drives the carrying jaws 310 away from the cutting and stripping knife assembly 410. As the wire moves away from the cutting and stripping knife assembly 410, the stripping knife can limit the insulation of the wire to achieve the stripping operation.

[0082] The cutting and peeling drive structure 420 includes a first threaded seat, a first bidirectional screw, and a cutting and peeling drive member. The upper and lower ends of the first bidirectional screw are respectively provided with two sections of thread with opposite rotation directions. The number of the first threaded seats is set to two, and the two first threaded seats are respectively threadedly connected to the two ends of the first bidirectional screw. The first threaded seats correspond one-to-one with the cutting and peeling knife groups 410, and the cutting and peeling knife groups 410 are fixedly connected to the first threaded seats. The cutting and peeling drive structure 420 can drive the two cutting and peeling knife groups 410 to move closer to or away from each other at the same time, thereby achieving the peeling and cutting operation. Specifically, in this embodiment, the wire pulling cutting and peeling device also includes a peeling length detection component 500. The peeling length detection component 500 is arranged on the side of the cutting and peeling component 400 away from the wire pulling component 200. The peeling length detection component 500 uses visual detection. The peeling length detection component 500 is used to detect whether the peeling length meets customer requirements. Specifically, in this embodiment, the number of end processing components is set to multiple, and the multiple end processing components are arranged along the first direction. Specifically, the number of end processing components is set to four. In other embodiments, the end processing components can also be set to three, two, five, etc.

[0083] Specifically, in this embodiment, the end processing component is configured as a terminal crimping machine. In other embodiments, the end processing component may also be configured as other conventional equipment for processing the ends of wires, such as a tinning machine.

[0084] The wire harness welding machine also includes a terminal appearance inspection assembly 1100, which is located in front of the end processing assembly at the front end.

The transport drive structure 330 is configured as a linear motor, and the two transport jaws 310 are respectively mounted on the two distancing structures 320, and both of the two distancing structures 320 are mounted on the output end of the transport drive structure 330. Specifically, the distancing structure 320 is composed of components such as a motor, a transmission belt, a transmission wheel, and a transmission screw. In other embodiments, the distancing structure 320 can also be configured as a conventional linear drive device. Those skilled in the art can select the distancing structure 320 according to actual needs. The transport drive structure 330 drives the two transport jaws 310 to move simultaneously in a first direction, and the distancing structure 320 drives the transport jaws 310 to move closer to or away from the clamping and cutting device in a second direction. Both transport jaws 310 are configured as pneumatic jaws. In other embodiments, the transport jaws 310 can also be configured as electric jaws.

[0087] The main transport component also includes two sets of wire limiting components 340, which are respectively arranged corresponding to the two transport clamps 310. The wire limiting components 340 are arranged on the side of the transport clamp 310 away from the wire feeding component 100, and the wire limiting components 340 move along the second direction with the transport clamp 310.

[0088] Specifically, the wire limiting assembly 340 includes a wire limiting member 350 and a wire limiting driver 360. Specifically, in this embodiment, the wire limiting driver 360 is configured as a swinging cylinder. In other embodiments, the wire limiting driver 360 can also be configured as another conventional rotary drive device, such as a swinging motor. The wire limiting driver 360 drives the wire limiting member 350 to swing about an axis parallel to the second direction. The wire limiting members 350 of the two wire limiting assemblies 340 move in opposite directions, causing the two wire limiting members 350 to move closer to or further away from each other. By providing the wire limiting member 350, the wire can be limited in position to prevent the portion of the wire away from the wire feeding assembly 100 from expanding too much, thereby affecting the normal operation of other components of the wire pulling, cutting, and stripping device. Specifically, the wire limiting member 350 includes a second limiting section and a first limiting section. The second limiting section and the first limiting section are arranged at an obtuse angle to form a wire limiting groove. The wire limiting groove can limit the wire to prevent it from dislodging from the wire limiting member 350.

[0089] Specifically, the number of main transport assemblies is set to multiple, and the multiple main transport assemblies are arranged along a first direction. The wire harness welding machine also includes a relay transport clamp 305, which is arranged between two adjacent main transport assemblies, and the two ends of the relay transport clamp 305 are respectively connected to the two adjacent main transport assemblies. Specifically, the number of main transport assemblies is set to four; the main transport assembly corresponding to the wire cutting and stripping device is set as the first main transport assembly 301, the main transport assembly corresponding to the multiple end processing assemblies is set as the second main transport assembly 302, and the other two main transport assemblies are set as the third main transport assembly 303 and the fourth main transport assembly 304, and the fourth main transport assembly 304 is arranged in front of the third main transport assembly 303.

[0090] For the first main carrying component 301, the two carrying clamps 310 are used to clamp the two ends of the wire respectively. One of the carrying clamps 310 takes over the end of the wire clamped on the wire pulling clamp 220, and the other carrying clamp 310 takes over the end of the wire at the clamping and cutting device. After the carrying clamp 310 at the clamping and cutting device clamps the wire, the corresponding away structure 320 drives the carrying clamp 310 to move in the direction away from the clamping and cutting device to pull the wire out of the wire output sleeve 111, thereby avoiding the wire being forcibly pulled out of the wire output sleeve 111 when the wire is subsequently carried along the first direction, thereby avoiding the wire from bending due to obstruction by the wire output sleeve 111, thereby ensuring the normal progress of subsequent processes.

[0091] The fourth main transport assembly 304 is not provided with a disengaging structure 320. For the second main transport assembly 302, the disengaging structure 320 drives one end of the wire toward the end processing assembly so that the end of the wire can be processed by the end processing assembly. After the end of the wire is processed by the end processing assembly, the disengaging structure 320 drives the one end of the wire away from the end processing assembly, so that the wire is away from the end processing assembly, and then the wire can continue to be transported forward smoothly.

[0092] The relay transfer clamp 305 includes a relay transfer driver and a relay clamping unit. The relay transfer driver is configured as a clamping cylinder. In other embodiments, the relay transfer driver can also be configured as an electric clamping unit. There are two relay clamping units, arranged along the third direction. The relay transfer driver drives the two relay clamping units toward or away from each other to clamp the wire. The two ends of the wire are clamped by the two relay clamping units, respectively.

[0093] In other embodiments, the number of main transport components of the wire harness welding machine can be set to one, and the relay transport clamp 305 can be eliminated, but this will result in a decrease in the processing efficiency of the wire harness welding machine. By providing the relay transport clamp 305 and multiple main transport components, the wire harness welding machine can simultaneously transport and process multiple wires, thereby effectively improving the processing efficiency of the wire harness welding machine.

[0094] The wire-paying assembly 600 includes a wire-paying swing drive 620 and a wire-paying clamp 610. The wire-paying swing drive 620 is a swinging cylinder. In other embodiments, the wire-paying swing drive 620 can also be set as a swinging motor. The wire-paying clamp 610 is fixedly connected to the output end of the wire-paying swing drive 620. The wire-paying clamp 610 is set as a pneumatic clamp. In other embodiments, the wire-paying swing drive 620 can also be set as an electric clamp, etc. The wire-paying clamp 610 is provided with two wire-paying clamping parts. When the wire-paying clamp 610 is working, the two wire-paying clamping parts move closer to or away from each other. The wire-paying clamping part is used to clamp one end of the wire. The wire-paying clamping part is eccentrically arranged. The eccentric arrangement of the wire-paying clamping part allows the wire-paying clamping part to drive one end of the wire to move along a circular arc when the wire-paying swing drive 620 is working, so that the two ends of the wire are away from each other.

[0095] When it is necessary to pay out the wire, the wire-paying clamp 610 clamps and takes over one end of the wire, and then the wire-paying swing drive 620 drives the wire-paying clamp 610 to swing, so that the wire-paying clamp 610 and one end of the wire gradually move toward the vertical line side. When the wire-paying clamp 610 and one end of the wire swing to a certain angle, the wire-paying clamp 610 is released, and one end of the wire falls to the vertical line side due to the action of gravity, and the other end of the wire is still clamped by the third main transport component 303. After the wire-paying is completed, the third main transport component 303 continues to transport the wire forward. Through this arrangement, the influence of one end of the wire on the subsequent processing steps can be avoided.

[0096] The wire bonding machine also includes a wire arrangement assembly 1300, which is positioned forward of the pay-off assembly 600 in the first direction. This assembly includes an arrangement rotation driver, two offset drivers 1320, and two arrangement clamps 1310. The arrangement rotation driver is configured as a swing cylinder. In other embodiments, the arrangement rotation driver can also be configured as another conventional rotation drive device, such as a swing motor.

[0097] The misalignment driver 1320 is fixedly mounted on the aligning rotation driver. There is a one-to-one correspondence between the misalignment driver 1320 and the aligning jaws 1310. The misalignment driver 1320 is a linear cylinder, but can also be configured as another conventional linear drive device such as a linear motor. The aligning jaws 1310 are fixedly mounted on the output end of the misalignment driver 1320. The misalignment driver 1320 drives the aligning jaws 1310 to move linearly, causing the two aligning jaws 1310 to be misaligned or aligned.

[0098] In the initial state, the two arranging jaws 1310 are in a dislocated state, and the arranging jaw 1310 on the front side is arranged below the arranging jaw 1310 on the rear side. When two wires need to be arranged, the arranging jaw 1310 on the front side first clamps one wire, and then the two dislocation driving members 1320 work simultaneously or separately at a certain time interval, so that the positions of the two arranging jaws 1310 change, so that the arranging jaw 1310 on the front side is arranged below the arranging jaw 1310 on the rear side. Above, the arranging jaws 1310 at the rear side then clamps another wire; after the two wires are clamped, one or two of the offset driving members 1320 work to align the two arranging jaws 1310, and then the arranging rotation driving member drives the two arranging jaws 1310 to rotate, so that the two arranging jaws 1310 are converted to an upper and lower arrangement state, so that the ends of the two wires are arranged up and down, and then the fourth main transporting component 304 transports the two wires arranged up and down forward to prepare for the next step.

[0099] The device also includes a heat shrink tubing assembly 1000, which includes a heat shrink tubing feeding mechanism 1010 and a heat shrink tubing threading mechanism 1020. Heat shrink tubing feeding mechanism 1010 is a conventional vibrating plate feeding structure. Heat shrink tubing threading mechanism 1020 includes a threading clamp and a threading driver, which drives the threading clamp to move in the second direction.

[0100] Two welding transfer assemblies 700 are provided, and the two welding transfer assemblies 700 are arranged along the first direction. The welding transfer assemblies 700 are docked with the front end of the fourth main transport assembly 304. The welding transfer assembly 700 includes a multi-axis drive device 720 and a welding transfer clamp 710. Specifically, the multi-axis drive device 720 includes a first drive structure 721, a second drive structure 722, a third drive structure 723, and a fourth drive structure 724. The first drive structure 721 drives the welding transfer clamp 710 to rotate about an axis parallel to the swing axis. The second drive structure 722 drives the welding transfer clamp 710 to move vertically up and down. The third drive structure 723 drives the welding transfer clamp 710 to move parallel to the second direction. The fourth drive structure 724 drives the welding transfer clamp 710 to move parallel to the first direction. The welding transfer clamp 710, the first drive structure 721, the second drive structure 722, the third drive structure 723, and the fourth drive structure 724 are connected in sequence.

[0101] The welding device 900 is fixedly installed on the frame 001. Specifically, the welding device 900 is an ultrasonic welding device. In other embodiments, the welding device 900 can also be set as other conventional welding equipment.

[0102] One of the welding transfer components 700 first clamps the wire and moves it horizontally to the front side of the welding device 900, and then the multi-axis drive device 720 drives the welding transfer clamp 710 to rotate so that the end of the wire faces the welding device 900; then another welding transfer component 700 takes the wire and moves it to the back side of the welding device 900. At this time, the two welding transfer clamps 710 are respectively arranged on both sides of the welding device 900, and the two groups of wires are respectively located on the front and back sides of the welding device 900, and then the welding device 900 welds the two wires.

[0103] The implementation process of this scheme is as follows: after the wire clamping assembly 140 of the wire feeding assembly 100 transports the wire forward a certain distance, the wire pulling claw 220 clamps the wire extending out of the wire output sleeve 111, and then the wire pulling swing drive 210 drives the wire pulling claw 220 to swing, and at the same time the wire clamping assembly 140 continues to transport the wire forward so that the wire is U-shaped. When the wire moves forward to a certain length, the clamping and cutting device cuts the wire, and the wire clamping assembly 140 stops working.

[0104] The first main carrying component 301 works, one of the carrying jaws 310 clamps the end of the wire at the wire pulling jaw 220, and the other carrying jaw 310 is driven away from the structure 320 and close to the wire output sleeve 111, and then the carrying jaw 310 clamps the end of the wire at the wire output sleeve 111, and then the carrying jaw 310 is driven away from the structure 320 away from the wire output sleeve 111, and then the wire pulling jaw 220 releases its clamping of the wire. Then the carrying jaws 310 carry the wire forward along the first direction and carry the wire to the cutting and stripping assembly 400. The away structure 320 drives the two carrying jaws 310 close to the cutting and stripping assembly 400. The cutting and stripping assembly 400 cuts and strips the two ends of the wire. After the cutting and stripping is completed, the away structure 320 drives the two carrying jaws 310 away from the cutting and stripping assembly 400. Then the main carrying assembly continues to carry the wire forward and carries the wire to the stripping length detection assembly 500 for detection of the wire. After the detection is completed, the main carrying assembly continues to carry the wire forward and cooperates with other equipment or other components in the same equipment to process the wire.

[0105] The relay transfer clamp 305 located between the first main transport assembly 301 and the second main transport assembly 302 takes over the wire of the first main transport assembly 301, and the transport clamp 310 of the first main transport assembly 301 is reset and waits for the next wire transport.

[0106] The carrying jaws 310 of the second main carrying component 302 move to the relay transfer jaws 305, and then the carrying jaws 310 of the second main carrying component 302 take over the wire, and the second main carrying component 302 transports the wire forward to the end processing component. According to the program settings, the wire is processed in a single or multiple end processing components.

[0107] After the end of the wire is processed, the second main transport assembly 302 continues to transport the wire forward.

[0108] When the second main transport assembly 302 transports the wire to the relay transport clamp 305, the relay transport clamp 305 clamps both ends of the wire. Then the transport clamp 310 of the third main transport assembly 303 moves to the relay transport clamp 305 and clamps the end of the wire. The third main transport assembly 303 continues to transport the wire forward to the end processing assembly and the wire pay-off assembly 600. At the wire pay-off assembly 600, the wire pay-off clamp 610 clamps the wire and swings to a certain angle. Then the wire pay-off clamp 610 releases, and one end of the wire hangs down to the vertical line side.

[0109] Then the third main transport assembly 303 continues to transport the wire.

[0110] The fourth main transport assembly 304 clamps the conductor of the third main transport assembly 303 , and the third main transport assembly 303 is reset.

[0111] For wires that do not require heat shrink tubing, the fourth main transport assembly 304 transports the wires forward, and then the welding transfer clamp 710 clamps the ends of the wires. The multi-axis drive device 720 drives the welding transfer clamp 710 to move to the front side of the welding device 900.

[0112] If the program requires the wires to be heat-shrink-tubed, the fourth main transport assembly 304 transports the wires to the heat-shrink tubing assembly 1000. At the heat-shrink tubing assembly 1000, the heat-shrink tubing assembly applies the tubing to the wires. After the tubing is applied, another welding transport clamp 710 clamps the end of the wire, and the multi-axis drive 720 drives the welding transport clamp 710 to move to the rear side of the welding device 900. The welding device 900 then welds the wires on both sides, securing the wires on both sides of the welding device 900. After welding is complete, the leading welding transport clamp 710 clamps the welded wires, and the multi-axis drive 720 drives the welding transport clamp 710 to move to the front end of the wire harness welding machine, preparing for docking with the next production line or device.

These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
