Description

Technical Field

[0001] This invention relates to the field of automated wire harness production equipment, and more specifically, to a high-speed wire welding device and its method of use based on magnetic levitation conveying. Background Technology

[0002] As electronic devices become smaller and higher frequency-sensitive, the processing requirements for high-speed transmission cables are becoming increasingly stringent. In the welding process of high-speed electronic cables (such as high-speed data cables), it is typically necessary to precisely weld the cable body to the metal shell and the rubber core. Existing processing equipment mostly uses rotary or belt conveyor systems, which have the following main drawbacks:

[0003] Insufficient transmission accuracy: Traditional chain or turntable drives have mechanical backlash, making it difficult to achieve micron-level repeatability in positioning, which leads to welding misalignment.

[0004] Severe process interference: When stripping and shaping cables, the pre-installed iron shell or plastic core often hinders the processing, and manual intervention greatly reduces production efficiency.

[0005] Grounding wire handling is difficult: the bending, positioning and cutting of fine grounding wires still largely rely on manual or semi-automatic mechanisms, resulting in poor consistency and a high risk of short circuits. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of this invention is to provide a high-speed wire welding device and its usage method based on magnetic levitation conveyor flow.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A high-speed wire welding device based on magnetic levitation conveyor flow includes:

[0009] Machine tool;

[0010] A magnetic levitation transport system includes a magnetic levitation transport unit installed on the machine platform and a magnetic levitation transport seat floating thereon;

[0011] The fixture part, fixed on the magnetic levitation carrier, includes a carrier body and a core support that can move vertically to the side of the carrier body;

[0012] Multiple processing units are distributed around the trajectory of the magnetically levitated carrier.

[0013] The core support is movably locked to the seat body by a limiting rod, so as to sink and avoid displacement during the online machining process and rise and reset during the welding process.

[0014] Furthermore, the fixture also includes a wire clamping part and an elastic lifting part rotatably connected to the upper end of the base. By pressing the elastic lifting part, the wire clamping part is driven to open or close, so as to achieve clamping and positioning of the wire.

[0015] Furthermore, the processing unit includes a first processing unit, which includes a lower iron shell cutting unit and a rubber core cutting unit, for cutting the lower iron shell and rubber core in sequence and placing them on the shell core support seat in the rising position.

[0016] Furthermore, the processing unit includes a third processing unit, which is equipped with a lever clamp and a material support frame. The lever clamp is used to pull the limiting rod to release the lock, so that the shell core support seat can be lowered in height under the support of the material support frame.

[0017] Furthermore, the processing unit includes a fourth processing unit, which integrates a UV laser unit, an aluminum foil oscillation unit, and an aluminum foil transfer unit. The aluminum foil layer on the production line is removed by combining laser cutting with mechanical oscillation and transfer.

[0018] Furthermore, the processing unit includes a fifth processing unit, which is equipped with a ground wire bending unit and a ground wire splitting unit. The ground wire bending unit rotates the pneumatic gripper 90° driven by a motor to achieve vertical flipping of the ground wire. The ground wire splitting unit splits the two ground wires to the sides in a V shape using a splitting lever.

[0019] Furthermore, the processing unit includes a sixth processing unit, which is equipped with a carrier lifting unit and a precision alignment unit. The carrier lifting unit raises the core support to be flush with the base and relocks it. The precision alignment unit pushes the core and conductor together through the alignment seat according to the CCD detection result.

[0020] Furthermore, the processing unit includes a seventh processing unit, which integrates a welding unit, a tensile testing unit, and an electrical testing unit, respectively used for core welding, weld strength testing, and continuity testing.

[0021] Furthermore, the processing unit includes a tenth processing unit, which is provided with an elastic tangent section. The elastic tangent section is driven to descend by a seventeenth cylinder to cut off the excess length of the welded ground wire.

[0022] A method of using a high-speed wire welding device includes the following steps:

[0023] S1. Loading and alignment: The magnetic levitation carrier moves the fixture to the first processing unit to complete the loading of the lower iron shell and the rubber core.

[0024] S2, Sinking and Avoiding Position: The third processing unit unlocks the limit rod, the shell core support seat descends, and then the upper line section feeds the line body onto the support body;

[0025] S3. Wire processing: With the core support in the lower position, aluminum foil removal, ground wire flipping, insulation stripping and conductor cutting are performed in sequence.

[0026] S4, Reset: The sixth processing unit resets the core support to the high position and locks it, performing fine alignment of the conductor and the core;

[0027] S5. Welding Test: Perform laser welding and complete tensile and continuity tests online;

[0028] S6. Packaging and unloading: After the upper iron shell welding and ground wire removal are completed, the shell core support seat moves down again to let the finished product hang down naturally, and the material handling robot grabs and unloads it.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] (1) The present invention adopts magnetic levitation conveying technology, which eliminates the wear and vibration of traditional mechanical transmission and ensures the positioning accuracy of the fixture when switching between processing units; thus achieving high precision and high stability of automated processing.

[0031] (2) The present invention adopts a lifting shell core support design, which allows materials to actively "avoid" each other during processing, solving the problem of space collision when handling complex wires; and improving space utilization and process flexibility.

[0032] (3) The present invention requires no manual intervention in the entire process from feeding, cutting, peeling, shaping, welding, testing to sealing, which greatly reduces labor costs and shortens the production cycle; it is highly integrated and saves manpower. Attached Figure Description

[0078] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0079] A high-speed wire welding device based on magnetic levitation conveying includes a machine base 1, a magnetic levitation transport unit 2 fixed on the machine base 1, a magnetic levitation transport seat 21 floatingly connected to the magnetic levitation transport unit 2, a fixture unit fixed on the magnetic levitation transport seat 21, multiple processing units fixed on the machine base 1 (first processing unit 3, second processing unit 4, third processing unit 5, fourth processing unit 6, fifth processing unit 7, sixth processing unit 8, seventh processing unit 9, eighth processing unit 10, ninth processing unit 11, tenth processing unit 12, eleventh processing unit 13), a wire loading unit 51 located in front of the machine base 1 (which uses a robotic arm to grasp and transport the wire and load it onto the fixture unit), a material picking robot 14 located behind the machine base 1, and a material receiving unit 15. The material picking robot 14 is used to remove the wire from the fixture unit and transport it to the material receiving unit 15; the material receiving unit 15 is used to collect the wire after welding.

[0080] like Figure 3 and Figure 4As shown, the fixture includes a base 22 fixed to the upper end of the magnetic levitation carrier 21, an elastic lifting part 24 movably connected inside the base 22, a clamping part 23 rotatably connected to the upper end of the base 22 and linked to the elastic lifting part 24, a core support 25 slidably connected to the side of the base 22 facing the machine tool 1, a limiting groove 251 opened on the side of the core support 25 facing the base 22, and a limiting rod 26 movably inserted into the base 22 with one end inserted into the limiting groove 251 to limit the core support 25; the fixture is moved by magnetic levitation, making the movement position of the fixture more precise and improving the accuracy of automated processing;

[0081] By pulling the limiting rod 26, one end of the limiting rod 26 can be moved out of the limiting groove 251. At this time, the core support seat 25 can move up and down on one side of the seat body 22. The upper end of the core support seat 25 is used to place the iron shell (two iron shells, the upper iron shell is used to be welded to the ground wire of the wire) and the rubber core (located between the two iron shells and welded to the conductor of the wire).

[0082] One end of the elastic lifting part 24 (composed of a spring, a sliding plate, etc., with one end of the clamping part 23 rotatably connected to the base 22 and the other end rotatably connected to the sliding plate, the sliding plate moving up and down drives the clamping part 23 to rotate based on the axis of the base 22) extends out from the upper end of the base 22. By pressing the extended end of the elastic lifting part 24, the clamping part 23 can be driven to rotate on the base 22, thereby unfolding the clamping part 23 and the upper end of the base 22, making it easy to put the line between the base 22 and the clamping part 23; when the pressure on the elastic lifting part 24 is released, the elastic lifting part resets and drives the clamping part 23 to rotate and press on the line, clamping and positioning the line.

[0083] like Figure 5 and Figure 6 As shown, the first processing unit 3 includes a lower iron shell cutting unit 31 and a core cutting unit 32 fixed on the upper end of the machine base 1. When the fixture moves to the lower iron shell cutting unit 31, the lower iron shell on the material strip is cut off and falls onto the core support seat 25. When the fixture moves to the core cutting unit 32, the core on the material strip is cut off and falls into the lower iron shell on the core support seat 25.

[0084] The lower metal shell cutting unit 31 includes a first material conveying part 311, a first material tray 312, a first cutting part 313, and a first cutting part 314, all fixed to the upper end of the machine base 1; the core cutting unit 32 includes a second material conveying part 321, a second material tray 322, a second cutting part 323, and a second cutting part 324, all fixed to the upper end of the machine base 1.

[0085] The iron shell strip and the rubber core strip are wound on the first material tray 312 and the second material tray 322 respectively. The first material tray 312 and the second material tray 322 can rotate to feed the strip. The first material conveying part 311 and the second conveying part are composed of a servo motor 723 and a wheel. The outer surface of the wheel is provided with multiple flanges at equal intervals. The multiple flanges match the through holes opened on the strip. The servo motor 723 drives the wheel to rotate, and the wheel drives the strip to move through the flanges. The first cutting part 314 and the second cutting part 324 are composed of a cutting cylinder and a cutting head. The cutting cylinder extends and drives the cutting head to descend. The cutting head cuts off the iron shell or rubber core on the strip and makes the iron shell and rubber core fall on the shell and core support seat 25. The first cutting part 313 and the second cutting part 323 are also composed of a cutting cylinder and a cutting head. However, the function of the cutting part is to cut the strip (the strip segment without iron shell or rubber core).

[0086] like Figure 6 As shown, the second processing unit 4 includes a bracket 41 fixed to the upper end of the machine base 1, an X-axis moving platform 44, a pusher seat 43 fixed to the moving end of the X-axis moving platform 44, a pressing part 42 fixed to one side of the bracket 41, and a detection part 45 and a detection part 46 fixed to the upper end of the machine base 1. The pressing part 42 consists of a pressing cylinder 921 and a pressing block. When the core support 25 moves below the pressing part 42, the pressing cylinder 921 extends to drive the pressing block down and presses it against the core support. On the 25th, the X-axis moving platform 44 can drive the pusher 43 to move forward (towards the core support 25), and push the iron shell at the upper end of the core support 25 to move backward, thereby adjusting the position of the iron shell; the detection unit 45 can perform CCD detection on the iron shell and the core on the core support 25 from the front of the core support 25; the detection unit 46 can perform CCD detection on the iron shell and the core on the core support 25 from above the core support 25.

[0087] like Figure 7 and Figure 8 As shown, the third processing unit 5 includes a cylinder 1 52 fixed to the upper end of the machine base 1, a support plate 53 fixed to the telescopic end of the cylinder 1 52, a cylinder 2 54 fixed to the upper end of the support plate 53, a material support frame 1 55 fixed to the telescopic end of the cylinder 2 54, a cylinder 3 56 fixed to the upper end of the machine base 1, a lever clamp 1 57 fixed to the telescopic end of the cylinder 3 56, a cylinder 4 58 fixed to the upper end of the machine base 1, and a pressure seat 1 59 fixed to the telescopic end of the cylinder 4 58.

[0088] After the iron shell is pushed, the fixture unit moves to the third processing unit 5. The limiting rod 26 on the fixture unit moves horizontally into the interior of the rod clamp 57. The rod clamp 57 has a horizontal groove for the limiting rod 26 to move horizontally (in and out) in the horizontal groove. The wire needs to be loaded onto the seat 22 through the wire loading unit 51 and then processed (removing aluminum foil, removing insulation, conductor shaping, etc.). At this time, the core support seat 25 needs to be lowered to avoid obstruction, so as to facilitate the subsequent processing of the conductor. The cylinder 2 54 extends and drives the material support frame 55 to move towards the core support seat 25, so that the upper end of the material support frame 55 can be aligned with the core support seat 25. The lower end of the core support seat 25 contacts; then the control cylinder 3 56 retracts, the retraction of cylinder 3 56 drives the pull rod clamp 1 57 to move backward, the pull rod clamp 1 57 moves backward and drives the limit rod 26 to move backward, one end of the limit rod 26 moves out of the limit groove 251, canceling the limit on the core support seat 25; at this time, the extension end of cylinder 1 52 extends and drives the material support frame 1 55 to move downward, the core support seat 25 on the material support frame 1 55 is also affected by gravity and descends with the core support seat 25, at this time the upper end of the core support seat 25 is not on the same plane as the upper end of the seat body 22, and the height of the iron shell and rubber core on the core support seat 25 decreases;

[0089] After descending, the core support 25 and the seat 22 move to below the pressure seat 59. The cylinder 4 58 works to drive the pressure seat 59 to descend. The pressure seat 59 presses on the upper end of the elastic lifting part 24. The descent of the elastic lifting part 24 drives the wire clamping part 23 to rotate and open. At this time, the wire is placed on the seat 22 through the upper wire part 51. The cylinder 4 58 works to drive the pressure seat 59 to rise. The elastic lifting part 24 resets and drives the wire clamping part 23 to rotate and reset. The wire clamping part 23 clamps and positions the wire on the seat 22.

[0090] like Figure 9 and Figure 10As shown, the upper end of the machine tool 1 is fixed with a wire positioning part 61 (more than one, and multiple parts are also set in subsequent processing units, used to clamp and position the free end of the wire on the base 22 after the fixture part moves to the processing position; it consists of an L-shaped frame, two symmetrically arranged positioning cylinders, and two positioning chucks fixed to the telescopic ends of the two positioning cylinders respectively, one of the positioning cylinders being fixed to one side of the L-shaped frame. When the fixture part moves to the processing position, the telescopic ends of the two positioning cylinders extend, driving the two positioning chucks to move towards each other, clamping the free end of the wire. Clamping); the fourth processing unit 6 includes a UV laser unit 62 fixed to the upper end of the machine base 1 (used to cut the aluminum foil layer on the wire by laser cutting, the cut aluminum foil is detached by aluminum foil swinging, and then the detached aluminum foil is removed by aluminum foil shifting), a Z-axis moving platform 63, an X-axis moving platform 65, a UV laser unit 68 (used to perform secondary cutting on the broken edge of the aluminum foil layer on the wire by laser cutting, so that the broken edge of the aluminum foil layer is more flat), an X-axis moving platform 69, and a cylinder 693.

[0091] An aluminum foil swing part 64 is fixed on the moving end of the Z-axis moving platform 63. The aluminum foil swing part 64 consists of two swing cylinders and swing chucks. When the free end of the line on the fixture moves between the two swing chucks, the telescopic end of the swing cylinder extends and drives the two swing chucks to move towards each other and clamp the free end of the line. Then, the Z-axis moving platform 63 drives the two swing chucks and the line to perform up-and-down reciprocating motion (small amplitude) in the Z-axis, so that the aluminum foil that has been laser-cut on the line is loosened.

[0092] The moving end of the X-axis moving platform 2 65 is fixed with the Z-axis moving platform 2 66, and the moving end of the Z-axis moving platform 2 66 is fixed with the aluminum foil transfer part 67. The Z-axis moving platform 2 66 has two sets of lead screws and sliding sleeves (moving ends). Two transfer chucks are fixed on the two sliding sleeves respectively. When the free end of the line on the fixture moves between the two transfer chucks, the Z-axis moving platform 2 66 works to drive the two transfer chucks to move towards each other and clamp the free end of the line (the loosened aluminum foil). Then the X-axis moving platform 2 65 drives the Z-axis moving platform 2 66 and the aluminum foil transfer part 67 to move backward as a whole, so that the loosened aluminum foil on the line is removed from the line, completing the transfer operation.

[0093] The X-axis moving platform 369 has a Z-axis moving platform 3691 fixed on its moving end, and a shaping cutter head is fixed on the moving end of the Z-axis moving platform 3691. After the UV laser unit 268 performs secondary cutting on the aluminum foil break on the wire, the wire moves to the front of the shaping cutter head. The X-axis moving platform 369 drives the Z-axis moving platform 3691 and the shaping cutter head to move forward, so that the shaping cutter head reaches above the wire. The Z-axis moving platform 3691 drives the shaping cutter head to descend and mechanically cut the aluminum foil on the wire that has undergone secondary laser cutting. After the cutting is completed, the X-axis moving platform 369 drives the Z-axis moving platform 3691 and the shaping cutter head to move backward and reset. At this time, the shaping cutter head can take the cut aluminum foil off the wire by translating. Then the Z-axis moving platform 3691 drives the shaping cutter head to rise and reset, completing the mechanical break flattening treatment of the aluminum foil.

[0094] The telescopic end of cylinder 5 693 is fixed with a core wire pressure head 694. When the fixture moves the wire body below the core wire pressure head 694, cylinder 5 693 works to drive the core wire pressure head 694 to descend. The core wire pressure head 694 presses down on the core wire part (insulation part) of the wire body, so that the core wire part (insulation part) cannot be on the same plane as the left and right ground wires.

[0095] like Figures 11 to 13 As shown, the fifth processing unit 7 includes a wire support frame 71 fixed to the upper end of the machine base 1 (used to support the rear end of the wire extending from the fixture), a ground wire bending unit 72, a ground wire separating unit 73, an insulation straightening unit 74, and an insulation stripping unit 75.

[0096] The ground wire bending unit 72 includes an X-axis moving platform 4 fixed to the upper end of the machine base 1, an outer frame 722 fixed to the moving end of the X-axis moving platform 4 721, a tilting frame 724 rotatably connected to the inner wall of the outer frame 722, a motor 723 fixed to the upper end of the outer frame 722, and a pneumatic gripper 725 fixed to the upper end of the tilting frame 724. The output shaft of the motor 723 is connected to the tilting frame 724 through a transmission part (synchronous pulley and synchronous belt). When the wire moves to the ground wire bending unit 72, the wire enters between the two gripping arms of the pneumatic gripper 725. The pneumatic gripper 725 works and clamps the ground wire of the wire through the two gripping arms. Then the motor 723 drives the tilting frame 724 to tilt. The tilting frame 724 tilts 90°, and the pneumatic gripper 725 on the tilting frame 724 tilts synchronously with the tilting frame 724, thereby bending the clamped ground wire. Bending the ground wire upward makes it easier for the ground wire to enter the slot reserved in the upper iron shell.

[0097] The ground wire splitting unit 73 includes a cylinder 6 731 fixed to the upper end of the machine base 1, a cylinder gripper 732 fixed to the telescopic end of the cylinder 6 731, and two wire splitting paddles 733 respectively fixed to the two gripping arms of the cylinder gripper 732. When the wire after the ground wire bending process moves to the ground wire splitting unit 73, the telescopic end of the cylinder 6 731 extends and drives the cylinder gripper 732 to move forward, so that the wire splitting paddles 733 on the two gripping arms of the cylinder gripper 732 enter between the two ground wires. Then the cylinder gripper 732 works to make the two gripping arms move in opposite directions. The two gripping arms drive the two wire splitting paddles 733 to move in opposite directions. The two wire splitting paddles 733 drive the two ground wires that have been bent to move in opposite directions, so that the distance between the two ground wires increases and the two ground wires change from the initial vertical state after being bent to a V-shaped state after being separated.

[0098] The insulation straightening unit 74 includes an X-axis moving platform 5 741 fixed to the upper end of the machine base 1, a Z-axis moving platform 4 742 fixed to the moving end of the X-axis moving platform 5 741, and a straightening pressure head (not shown in the figure) fixed to the moving end of the Z-axis moving platform 4 742. The Z-axis moving platform 4 742 has two opposing moving ends (two sets of symmetrical threads are provided on a lead screw, and two symmetrical sliding sleeves are screwed on). A straightening pressure head is fixed on both moving ends. After the wire passes through the grounding wire treatment and moves to the insulation straightening unit 74, the X-axis moving platform 5 741 moves to the upper end of the machine base 1. The five-axis moving platform 741 drives the four-axis moving platform 742 and the straightening pressure head to move forward (towards the wire), so that the wire enters between the upper and lower straightening pressure heads. The four-axis moving platform 742 drives the two straightening pressure heads to move towards each other, so that the two straightening pressure heads clamp the wire. During the clamping process, the lower straightening pressure head can push the pressed core wire part to move upward and reset. At the same time as moving upward and resetting, it can also cut the insulation layer of the core wire part, thereby realizing the straightening of the core wire part and the cutting of the insulation layer.

[0099] The insulation stripping unit 75 includes an X-axis moving platform six 751 fixed to the upper end of the machine base 1, a Z-axis moving platform five 752 fixed to the moving end of the X-axis moving platform six 751, and a stripping blade holder 753 fixed to the moving end of the Z-axis moving platform five 752. The Z-axis moving platform five 752 has two sets of lead screw drive mechanisms, and two stripping blade holders 753 are fixed to the moving ends of the two sets of lead screw drive mechanisms respectively. When the core wire is straightened and moved to the insulation stripping unit 75... At that time, the X-axis moving platform six 751 drives the Z-axis moving platform five 752 and the stripping knife holder 753 to move forward, so that the straightened core wire enters between the two stripping knife holders 753. The Z-axis moving platform drives the two stripping knife holders 753 to move towards each other, and the two stripping knife holders 753 enter the cut of the insulation layer on the core wire. Then, the moving end of the X-axis moving platform six 751 moves backward to reset and drives the stripping knife holder 753 to translate, removing the cut insulation layer from the core wire.

[0100] like Figure 14 and Figure 15 As shown, the sixth processing unit 8 includes a UV laser unit 3 81 fixed on the machine base 1, a conductor cutting unit 82, a carrier moving unit 83, a preliminary alignment unit 84, a detection unit 3 85, a fine alignment unit 86, and a detection unit 4 87; the UV laser unit 3 81 can perform laser deburring on the cut edges of the insulation layer.

[0101] The conductor cutting unit 82 includes an X-axis moving platform 821 fixed to the upper end of the machine base 1, a cylinder 822 fixed to the moving end of the X-axis moving platform 821, and a cutting blade holder 823 fixed to the telescopic end of the cylinder 822. After the wire body is deburred by the UV laser unit 81, it moves to the conductor cutting unit 82. The X-axis moving platform 821 drives the cylinder 822 and the cutting blade holder 823 to move forward, so that the cutting blade holder 823 moves above the wire body. The telescopic end of the cylinder 822 extends and drives the cutting blade holder 823 to descend. The cutting blade holder 823 cuts the conductor layer of the core wire, shortening the conductor and flattening the cut end of the conductor (which facilitates welding with the core).

[0102] The carrier lifting unit 83 includes a cylinder 831 fixed to the upper end of the machine base 1, a support plate 832 fixed to the telescopic end of the cylinder 831, a cylinder 9 833 fixed to the upper end of the machine base 1, and a lever clamp fixed to the telescopic end of the cylinder 9 833. After the conductor of the wire is cut short, it moves to the carrier lifting unit 83 along with the fixture. At this time, the support plate 832 is located below the core support 25. The cylinder 831 drives the support plate 832 to rise, and the support plate 832 drives the core support 25 to rise, so that the upper end of the core support 25 is flush with the upper end of the seat 22. Then the cylinder 9 833 extends to drive the lever clamp to move. The lever clamp drives the limiting rod 26 to move, so that one end of the limiting rod 26 is inserted into the limiting groove 251 on one side of the core support 25, thus limiting the core support 25 and preventing the core support 25 from descending on one side of the seat 22.

[0103] The initial alignment unit 84 includes a cylinder 841 fixed on the upper end of the machine tool 1 and an alignment seat 842 fixed on the telescopic end of the cylinder 841. When the core support seat 25 moves up and the fixture arrives at the initial alignment unit 84, the cylinder 841 drives the alignment seat 842 to descend. When the alignment seat 842 descends, the lower end of the alignment seat 842 can contact the core and the conductor, press down on the core and the conductor, and prevent the core from being suspended or the conductor from being lifted, thus providing a guarantee for subsequent welding.

[0104] The precision alignment unit 86 includes an X-axis moving platform 861 fixed to the upper end of the machine tool 1, an alignment seat 842 (not shown in the attached drawings) fixed to the moving end of the X-axis moving platform 861, an eleventh cylinder 862 fixed to the upper end of the machine tool 1, and an alignment pressure head (not shown in the attached drawings) fixed to the telescopic end of the eleventh cylinder 862. The position of the conductor, lower iron shell, and core after initial alignment is detected by the detection unit 85. Then, the fixture unit moves the production line to the precision alignment unit 86. At this time, the eleventh cylinder 862 can extend and drive the alignment pressure head to descend. The alignment pressure head descends and presses on the conductor. The X-axis moving platform 861 can drive the alignment seat 842 to move forward. The forward movement of the alignment seat 842 can push the core and lower iron shell to move backward, so that the core aligns with one end of the conductor, completing the precision alignment. After the precision alignment is completed, the position of the core and conductor is detected by the detection unit 87.

[0105] like Figures 16 to 18 , Figure 20 As shown, the seventh processing unit 9 includes a detection unit 5 91 fixed on the machine base 1, a welding unit 1 92, a detection unit 6 93, a ground wire flattening unit 94, a tensile testing unit 95, and an electrical testing unit 96. The detection unit 5 91 is used to detect the position of the core wire and the iron shell.

[0106] Welding unit 92 is used to weld the core and the conductor. Welding unit 92 consists of a laser welding part fixed on the upper end of the machine base 1 and a twelfth cylinder 941. A welding pressure head (not shown in the figure) is also fixed on the telescopic end of the twelfth cylinder 941. When the fixture moves to the lower part of the laser welding part, the twelfth cylinder 941 can retract and drive the welding pressure head to descend. The descending welding pressure head can press on the conductor and the core, ensuring the stability of the position during the welding process. Then the laser welding part performs laser welding on the connection between the conductor and the core.

[0107] Inspection Unit 693 is used for visual inspection of welded areas after welding is completed;

[0108] The ground wire flattening unit 94 includes a twelfth cylinder 941 and a thirteenth cylinder 943 fixed to the upper end of the machine base 1, a pressing seat 942 fixed to the telescopic end of the twelfth cylinder 941, and a pressing seat 944 fixed to the telescopic end of the thirteenth cylinder 943. When the welded conductor and the core move to the ground wire flattening unit 94, the twelfth cylinder 941 operates to drive the pressing seat 942 to descend. The pressing seat 942 descends and presses down on the core and the iron shell. Then, the thirteenth cylinder 943 operates to drive the pressing seat 944 to descend. The pressing seat 944 descends to perform wire pressing on the ground wire that has been split and formed into a V shape, pressing down the two ends of the V-shape upwards to make it straight. It should be noted that the pressing seat 942 has a through groove inside, and the pressing seat 944 can pass through the through groove to press down on the ground wire.

[0109] The tensile testing unit 95 includes a Z-axis moving platform 951 fixed to the upper end of the machine base 1, a fourteenth cylinder 953, a pressure seat 952 fixed to the moving end of the Z-axis moving platform 951, and a pressing seat 954 fixed to the telescopic end of the fourteenth cylinder 953. When the material after passing through the ground flattening unit 94 moves to the tensile testing unit 95, the fourteenth cylinder 953 retracts, causing the pressing seat 954 to descend, thus pressing and positioning the rubber core. Then, the Z-axis moving platform 951 moves, causing the pressure seat 952 to descend. The descending pressure seat 952 can press on the conductor welded to one end of the rubber core, realizing the tensile test of the weld. Specifically, a sensor can be installed on the side of the pressure seat 952 that contacts the conductor to detect the pressure and feed it back to the Z-axis moving platform 951 to achieve closed-loop control and realize the tensile test under a certain pressure.

[0110] The electrical testing unit 96 includes a fifteenth cylinder 961 and a sixteenth cylinder 963 fixed on the upper end of the machine base 1, a pressure seat 3 962 fixed on the telescopic end of the fifteenth cylinder 961, and a continuity testing part 964 fixed on the telescopic end of the sixteenth cylinder 963. When the material after the tensile test moves to the electrical testing unit 96, the fifteenth cylinder 961 operates to drive the pressure seat 3 962 to descend, and the pressure seat 3 962 descends and presses on the rubber core to press and position the rubber core. Subsequently, the sixteenth cylinder 963 operates to drive the continuity testing part 964 to move towards the rubber core, so that the probe of the continuity testing part 964 contacts the rubber core to realize the electrical test of the rubber core. The continuity testing part 964 uses an existing electrical testing instrument on the market, which will not be described in detail here.

[0111] like Figure 2 and Figure 19 As shown, the eighth processing unit 10 includes a glue spraying unit 101 and a curing unit 102 fixed on the upper end of the machine base 1. The glue spraying unit 101 consists of a three-axis moving module and a glue spraying module. The three-axis moving module drives the glue spraying module to move and adjust its position. The glue spraying module sprays glue at the welding point between the glue core and the iron shell. Both the three-axis moving module and the glue spraying module are mature existing technologies and will not be described in detail here. The curing unit 102 is used to cure the glue sprayed area. Curing is a mature existing technology and will not be described in detail here.

[0112] like Figure 2 and Figure 21 As shown, the ninth processing unit 11 includes a third material conveying unit 111, a third material tray 112, a third cutting unit 113, a third trimming unit 114, an inspection unit 115, and a welding unit 116, all fixed to the upper end of the machine base 1.

[0113] The iron-shell strip is wound onto the third tray 112, which can rotate to unload the strip. The third strip feeding unit 111 consists of a servo motor 723 and a wheel. Multiple flanges are equidistantly arranged on the outer surface of the wheel, and these flanges match the through holes in the strip. The servo motor 723 drives the wheel to rotate, and the wheel moves the strip via the flanges. The third cutting unit 114 consists of a cutting cylinder and a cutting blade. The cutting cylinder extends, causing the cutting blade to descend, cutting off the upper iron shell from the strip. The upper iron shell is placed on the material (the glue core and conductor that have been welded, glued, and cured) of the core support seat 25; the third cutting section 113 is also composed of a cutting cylinder and a cutting blade, but the function of the cutting section is to cut the strip (the strip segment that does not contain the iron shell); the position of the upper iron shell on the material is visually inspected by the detection section 7 115; the upper iron shell and the lower iron shell (located below the glue core) on the material can be welded by the welding unit 2 116, and the ground wires on both sides can also be welded to the iron shell.

[0114] like Figure 2 and Figure 22 As shown, the tenth processing unit 12 includes a mounting bracket 121 fixed to the upper end of the machine base 1, a seventeenth cylinder 122 fixed to one side of the mounting bracket 121, a slide table 123 slidably connected to one side of the mounting bracket 121 and connected to the telescopic end of the seventeenth cylinder 122, an elastic tangent part 124 fixed to one side of the slide table 123, a detection part 8 125 fixed to the upper end of the machine base 1, and a shell core support 25 lowering assembly;

[0115] After the upper and lower iron shells are welded together and the ground wire is welded to the iron shells, the material moves to the lower end of the elastic tangent section 124. The elastic tangent section 124 consists of a tangent blade and a spring for connecting the tangent blade to the slide table 123. The seventeenth cylinder 122 extends and drives the slide table 123 and the elastic tangent section 124 to descend. The tangent blade presses on the ground wire to cut off the excess ground wire that is too long. After cutting, the ground wire is detected by the detection unit 125.

[0116] The core support 25 lowering assembly includes an eighteenth cylinder 126 and a nineteenth cylinder 129 fixed to the upper end of the machine base 1, a frame 127 fixed to the telescopic end of the eighteenth cylinder 126, a support plate 128 fixed to the lower end of the frame 127, and a lever clamp fixed to the telescopic end of the nineteenth cylinder 129. After the ground wire is cut off, the core support 25 moves above the support plate 128, and the limiting rod 26 enters the transverse groove in the lever clamp. The nineteenth cylinder 129 retracts, causing the lever clamp to move backward. The lever clamp then moves the limiting rod 26 backward, causing the limiting rod 26 to move backward. One end moves out of the limiting groove 251, canceling the limitation on the core support seat 25. The eighteenth cylinder 126 extends and drives the second pallet 128 to move downward. At this time, the core support seat 25 on the second pallet 128 is not limited and is affected by gravity as the second pallet 128 descends. Since the material on the core support seat 25 (composed of upper iron shell, rubber core and lower iron shell) is welded to the conductor, the material will separate from the core support seat 25 and hang down naturally when the core support seat 25 descends. This is to facilitate the automated gripping and unloading of the material by the picking robot 14.

[0117] like Figure 2 and Figure 23 As shown, the eleventh processing unit 13 includes a twentieth cylinder 131 and a eleventh cylinder 134 fixed on the upper end of the machine base 1, a pressure seat 132 and a positioning rod 133 fixed on the telescopic end of the twentieth cylinder 131, a material support frame 135 fixed on the telescopic end of the eleventh cylinder 134, a twentieth cylinder 136 fixed on the upper end of the machine base 1, and a lever clamp 137 fixed on the telescopic end of the twentieth cylinder 136.

[0118] When the fixture, after being processed by the core support 25 downward assembly, moves to below the pressure seat 132, the robotic arm of the picking robot 14 will grab the free end of the wire on the wire support frame 71; then the twentieth cylinder 131 extends to drive the pressure seat 132 and the positioning rod 133 to descend. The positioning rod 133 is inserted into the positioning groove at the upper end of the seat 22. The pressure seat 132 is used to press down the upper end of the elastic lifting part 24. At this time, the wire clamping part 23 will rotate to release the clamping of the wire. One end of the wire on the wire support frame 71 is grabbed by the picking robot 14, and the other end, which is welded to the core, hangs naturally. After the wire clamping part 23 releases the clamping of the wire, the picking robot 14 can remove the entire wire from the fixture and transport it to the receiving part 15 to complete the unloading action.

[0119] Subsequently, the core support 25 moves above the material support frame 135. The twenty-first cylinder 134 operates, causing the material support frame 135 to rise. The material support frame 135 supports the core support 25 and raises it, making the upper end of the core support 25 flush with the upper end of the seat 22. Then, the twenty-second cylinder 136 operates, causing the pull rod clamp 137 to move towards the seat 22. The pull rod clamp 137 drives the limiting rod 26 to move, so that one end of the limiting rod 26 is inserted into the limiting groove 251 of the core support 25, limiting the core support 25. Then, the fixture part returns to the first processing unit 3 to realize automated cyclic processing. Alternatively, a mechanism for cleaning the core support 25 can be set on the machine tool 1. The residual material on the core support 25 is cleaned by brush cleaning and suction. After cleaning, it returns to the first processing unit 3.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
