Description

Technical Field

[0001] This invention relates to the field of stranded wire pin manufacturing technology, and more particularly to a multi-mode crimping device. Background Technology

[0002] Twisted wire flexible pins (commonly known as twisted pins) are made of two layers of multi-strand copper wire twisted in opposite directions, with the two ends fused together. One end is pressed into a sleeve, and the other end is upset and raised. They are characterized by light weight, small size, and reliable contact, and are widely used in electronic components.

[0003] During processing, different customers have different product requirements. Some customers need products with twisted needles and needle sleeves crimped together, some need products with twisted needles and wire harnesses crimped to both ends of the needle sleeve, and some need products with wire harnesses and needle sleeves crimped together. Different customers have different actual needs. The existing processing method is to manufacture separate equipment for crimping twisted needles and needle sleeves, equipment for crimping twisted needles, wire harnesses and needle sleeves, and equipment for crimping wire harnesses and needle sleeves.

[0004] This approach has the following problems: it requires preparing one device for each demand, which results in high production costs. Summary of the Invention

Detailed Implementation

[0035] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0036] like Figure 1 , Figure 2 as well as Figure 10As shown, an embodiment of the present invention provides a multi-mode crimping device, comprising: a base 1, a first needle sleeve feeding mechanism 2, a twisted needle feeding mechanism 3, a robotic arm carrying mechanism 4, a first crimping mechanism 5, a second needle sleeve feeding mechanism 6, a second crimping mechanism 7, and a manual threading mechanism 8. The first needle sleeve feeding mechanism 2, the twisted needle feeding mechanism 3, the robotic arm carrying mechanism 4, the first crimping mechanism 5, the second needle sleeve feeding mechanism 6, the second crimping mechanism 7, and the manual threading mechanism 8 are fixed on the base 1. The twisted needle feeding mechanism 3 is used to transport twisted needles from one side to the first crimping mechanism 5, and the first needle sleeve feeding mechanism 2 is used to transport a first needle sleeve to the first crimping mechanism 5 from the other side and press the first needle sleeve... The first crimping mechanism 5 is used to crimp the end of the twisted needle with the first needle sleeve on it. The robotic arm carrying mechanism 4 can send out or transport the first needle sleeve, which has been crimped with the twisted needle, to one side of the second crimping mechanism 7 for docking. The manual threading mechanism 8 is used to transport the thread bundle to the second crimping mechanism 7 from the other side and extend one end of the transported thread bundle into the other end of the first needle sleeve. The second crimping mechanism 7 is used to crimp the other end of the first needle sleeve. Alternatively, the second needle sleeve feeding mechanism 6 is used to transport the second needle sleeve from the side of the second crimping mechanism 7 away from the manual threading mechanism 8 to the second crimping mechanism 7 and place the second needle sleeve on one end of the thread bundle. The second crimping mechanism 7 is used to crimp the other end of the second needle sleeve.

[0037] Specifically, the base 1 has a flat, fixed surface on which the first needle sleeve feeding mechanism 2, the twisted needle feeding mechanism 3, the robotic arm carrying mechanism 4, the first crimping mechanism 5, the second needle sleeve feeding mechanism 6, the second crimping mechanism 7, and the manual threading mechanism 8 are fixed. The base 1 is equipped with power supply lines and air / oil supply lines, which are connected to the first needle sleeve feeding mechanism 2, the twisted needle feeding mechanism 3, the robotic arm carrying mechanism 4, the first crimping mechanism 5, the second needle sleeve feeding mechanism 6, the second crimping mechanism 7, and the manual threading mechanism 8, ensuring their normal operation. The power supply lines and air / oil supply lines are conventional technical means in this field, and those skilled in the art can make reasonable adjustments according to actual conditions; therefore, they will not be described in detail here.

[0038] Specifically, such as Figure 1 , Figure 2 as well as Figure 3As shown, the first needle sleeve feeding mechanism 2 includes a first needle sleeve circular vibrating plate 21, a first needle sleeve vibrator, a first needle sleeve feeding tube 22, and a first needle sleeve feeding component 23. The first needle sleeve circular vibrating plate 21 is fixed on the first needle sleeve vibrator. A spiral track is provided on the first needle sleeve circular vibrating plate 21. One end of the first needle sleeve feeding tube 22 is connected to the spiral track. The first needle sleeve feeding component 23 can move relative to the first needle sleeve feeding tube 22 and has at least a first needle sleeve access state connected to the first needle sleeve feeding tube 22 and a first needle sleeve delivery state connected to the first pressing mechanism 5. The first needle sleeve vibrator can drive the first needle sleeve circular vibrating plate 21 to vibrate vertically and to oscillate around its vertical axis, so that the twisted needle in the first needle sleeve circular vibrating plate 21 rises along the spiral track and is fed into the first needle sleeve feeding tube 22. When the first needle sleeve feeding member 23 is in the first needle sleeve receiving state, the first needle sleeve in the first needle sleeve feeding tube 22 is fed into the first needle sleeve feeding member 23. When the first needle sleeve feeding member 23 is in the first needle sleeve sending state, it docks with the first crimping mechanism 5 and feeds the first needle sleeve into the first crimping mechanism 5.

[0039] Furthermore, the first needle sleeve feeding component 23 includes a first needle sleeve feeding cylinder 231 and a first needle sleeve loading plate 232. The movable end of the first needle sleeve feeding cylinder 231 is fixed to the first needle sleeve loading plate 232, which can drive the first needle sleeve loading plate 232 to reciprocate and switch between the first needle sleeve receiving state and the first needle sleeve dispensing state. The first needle sleeve loading plate 232 is provided with a first needle sleeve through hole 233 for loading the first needle sleeve. The first needle sleeve through hole 233 matches the first needle sleeve. When the first needle sleeve feeding component 23 switches to the first needle sleeve receiving state, the first needle sleeve through hole 233 is connected to the first needle sleeve conveying pipe 22, and the first needle sleeve conveying pipe 22 inputs the first needle sleeve into the first needle sleeve through hole 233. When the first needle sleeve feeding component 23 switches to the first needle sleeve dispensing state, the first needle sleeve through hole 233 is connected to the first crimping mechanism 5, thereby completing the feeding process of the first needle sleeve.

[0040] Specifically, the twisted needle feeding mechanism 3 includes a twisted needle circular vibrating plate 31, a twisted needle vibrator, a twisted needle feeding tube 32, and a twisted needle feeding component 33. The twisted needle circular vibrating plate 31 is fixed on the twisted needle vibrator, and a spiral track is provided on the twisted needle circular vibrating plate 31. One end of the twisted needle feeding tube 32 is connected to the spiral track. The twisted needle feeding component 33 can move relative to the twisted needle feeding tube 32 and has at least a twisted needle access state connected to the twisted needle feeding tube 32 and a twisted needle delivery state connected to the first pressing mechanism 5. The twist needle vibrator can drive the twist needle circular vibrating plate 31 to vibrate vertically and torsionally around its vertical axis, causing the twist needles in the twist needle circular vibrating plate 31 to rise along the spiral track and be fed into the twist needle feeding tube 32. When the twist needle feeding member 33 is in the twist needle receiving state, the twist needles in the twist needle feeding tube 32 are fed into the twist needle feeding member 33. When the twist needle feeding member 33 is in the twist needle sending state, it docks with the first pressing mechanism 5 and feeds the twist needles into the first pressing mechanism 5.

[0041] Furthermore, the twisted needle feeding component 33 includes a twisted needle feeding cylinder 331 and a twisted needle loading plate 332. The movable end of the twisted needle feeding cylinder 331 is fixed to the twisted needle loading plate 332, enabling it to drive the twisted needle loading plate 332 to reciprocate, switching between the twisted needle input state and the twisted needle output state. The twisted needle loading plate 332 has a twisted needle through hole 333 for loading twisted needles. The needle through hole 333 is matched with the twist needle; when the twist needle feeder 33 switches to the twist needle input state, the twist needle through hole 333 is connected to the twist needle feed tube 32, and the twist needle feed tube 32 feeds the twist needle into the twist needle through hole 333. When the twist needle feeder 33 switches to the twist needle output state, the twist needle through hole 333 is connected to the first crimping mechanism 5, thereby completing the twist needle feeding process.

[0042] Specifically, such as Figure 7 , Figure 8 as well as Figure 9As shown, the robotic arm carrying mechanism 4 includes a robotic arm 41 and a loading head 42. The robotic arm 41 is fixed on the base 1, and the loading head 42 is fixed to the movable end of the robotic arm 41. The robotic arm 41 covers the first needle sleeve feeding mechanism 2, the twisted needle feeding mechanism 3, the first pressing mechanism 5, the second needle sleeve feeding mechanism 6, and the second pressing mechanism 7. It can drive the loading head 42 to dock with the first pressing mechanism 5 or with the second pressing mechanism 7. The loading head 42 has a loading through hole 421 for accommodating materials, and the loading through hole 421 can dock with the first pressing mechanism 5 or the second pressing mechanism 7.

[0043] Furthermore, the robotic arm carrying mechanism 4 also includes a support frame 43, a recognition camera 44, and a positioning pin 45. The support frame 43 is fixed on the base 1 and located on one side of the robotic arm 41. The recognition camera 44 is fixed on the top of the support frame 43. The positioning pin 45 is fixed on the support frame 43 and partially protrudes relative to the support frame 43. A notch 422 is provided on the loading head 42, and the notch 422 communicates with the loading through hole 421 so that at least part of the material in the loading through hole 421 is exposed. The robotic arm 41 can drive the loading head 42 to move so that the notch 422 is located below the recognition camera 44 at least at a certain moment, so that the loading through hole 421 can dock with the positioning pin 45. When the loading head 42 is docked with the first pressing mechanism 5, material is loaded into the loading through hole 421. The robotic arm 41 drives the loading head 42 to move, so that the loading through hole 421 docks with the positioning pin 45. The positioning pin 45 pushes the material into the loading through hole 421, so that the area on the material that has been pressed corresponds to the notch 422. The robotic arm 41 drives the loading head 42 to move, so that the notch 422 is located below the recognition camera 44, and identifies the twisted needle pressing area in the notch 422 to determine whether the pressing is qualified.

[0044] Specifically, such as Figure 2 , Figure 3 , Figure 4 as well as Figure 5As shown, the first crimping mechanism 5 includes a first crimping connector 51, a twisted needle insertion component 52, and a first needle sleeve insertion component 53. The first crimping connector 51 is disposed on the base 1. The twisted needle feeder 33 and the first needle sleeve feeder 23 are respectively located on both sides of the first crimping connector 51. The twisted needle insertion component 52 is disposed on the same side as the twisted needle feeder 33 and is used to insert the twisted needle on the twisted needle feeder 33 into the first crimping connector 51. The first needle sleeve insertion component 53 is disposed on the same side as the first needle sleeve feeder 23 and is used to insert the first needle sleeve on the first needle sleeve feeder 23 into the first crimping connector 51 and sleeve it on one end of the twisted needle. The first crimping connector 51 is used to crimp the end of the twisted needle on which the first needle sleeve is sleeved.

[0045] Furthermore, such as Figure 6 As shown, the first crimp connector 51 includes a first fixing ring 511, at least one first crimping assembly 512, and a first fixing base 513. The first crimping assembly 512 has two relatively movable crimping surfaces. The first crimping assembly 512 is embedded in the groove of the first fixing base 513. The inner wall of the first fixing ring 511 is provided with concave and convex surfaces corresponding to the first crimping assembly 512. When the first fixing ring 511 rotates to the point where the convex surface contacts the first crimping assembly 512, the two crimping surfaces of the first crimping assembly 512 move relative to each other, crimping the material located at the center of the first fixing ring 511. When the first fixing ring 511 rotates to the point where the concave surface contacts the first crimping assembly 512, the two crimping surfaces of the first crimping assembly 512 move away from each other, disengaging from the material located at the center of the first fixing ring 511. The twisted needle insertion component 52 and the first needle sleeve insertion component 53 respectively deliver the twisted needle and the first needle sleeve to the crimping surface. The crimping surface of the first crimping assembly 512 moves relative to each other to crimp the twisted needle and the first needle sleeve.

[0046] In this embodiment, the first crimp connector 51 has two first crimping assemblies 512, the axes of which are perpendicular to each other. The two first crimping assemblies 512 can crimp the twisted needle located at the center of the first retaining ring 511 from four directions.

[0047] Furthermore, the first pressing assembly 512 includes a first pressing block, a second pressing block, a first elastic element, and a second elastic element. One end of the first elastic element and the second elastic element are fixed to the first fixed base 513. The first pressing block is fixed to the other end of the first elastic element, and the second pressing block is fixed to the other end of the second elastic element. When the first fixed ring 511 rotates to the point where its concave surface contacts the first pressing assembly 512, the first elastic element and the second elastic element can drive the first pressing block and the second pressing block to move in opposite directions, so that the first pressing block and the second pressing block disengage from the material located at the center position of the first fixed ring 511.

[0048] In practice, the servo motor drives the first fixed ring 511 to rotate, causing the first crimping assembly 512 to work. When the first needle sleeve insertion component 53 blows the needle sleeve in, the three first crimping assemblies 512 work, and the first crimping block and the second crimping block move relative to each other, clamping the needle sleeve from six directions. When the first twisted needle insertion component 52 pushes the twisted needle into the needle sleeve, the three first crimping assemblies 512 continue to work, and the first crimping block and the second crimping block move relative to each other further, squeezing the needle sleeve so that the twisted needle and the needle sleeve are crimped together.

[0049] Furthermore, the twisted needle insertion component 52 includes a twisted needle insertion drive, a telescopic component 521, and an ejector pin 522. The twisted needle insertion drive is fixed to the telescopic component 521 and can drive the telescopic component 521 to move in a direction perpendicular to the first pressure joint 51. The ejector pin 522 is fixed on the telescopic component 521, coaxial with the twisted needle through hole 333 in the twisted needle delivery state, and located on the side of the twisted needle loading plate 332 away from the first pressure joint 51. The telescopic component 521 moves, driving the ejector pin 522 to push the twisted needle in the twisted needle through hole 333 into the first pressure joint 51. When the twisted needle feeder 33 switches to the twisted needle delivery state, the twisted needle through hole 333 is coaxial with the ejector pin 522. The telescopic member 521 moves, causing the ejector pin 522 to extend into the twisted needle through hole 333, pushing the twisted needle into the first crimping connector 51. It should be noted that the ejector pin 522 not only pushes the twisted needle into the first crimping connector 51, but also pushes the crimped twisted needle out of the first crimping connector 51. After crimping is complete, the telescopic member 521 continues to extend, causing the ejector pin 522 to continue moving along the twisted needle through hole 333, pushing the twisted needle out of the first crimping connector 51 from the other side. In this embodiment, the twisted needle insertion drive is a servo motor.

[0050] Specifically, the first needle sheath insertion component 53 includes a first needle sheath blowing device 531 and a telescopic cylinder 532. The telescopic cylinder 532 is fixed on the side of the first pressure joint 51 away from the twisted needle insertion component 52. The first needle sheath blowing device 531 is fixed on the movable end of the telescopic cylinder 532. The telescopic cylinder 532 can drive the first needle sheath blowing device 531 to reciprocate in a direction perpendicular to the first pressure joint 51. When the telescopic cylinder 532 is extended to its maximum state, the first needle sheath blowing device 531 abuts against the first needle sheath loading plate 232 in the first needle sheath delivery state. The air outlet of the first needle sheath blowing device, the first needle sheath through hole 233, and the center position of the fixing ring 511 are coaxial. The first needle sheath blowing device blows air into the first needle sheath through hole 233, causing the first needle sheath to be blown into the first pressure joint 51. When the telescopic cylinder 532 is retracted to its minimum state, a first gap is formed between the first needle sleeve blowing device 531 and the first crimping joint 51, which can accommodate the loading head 42. The robotic arm 41 drives the loading head 42 to move to the first gap, and the loading through hole 421 aligns with the first crimping joint 51. The telescopic member 521 continues to extend, causing the ejector pin 522 to continue moving along the twisted needle through hole 333, pushing the twisted needle in the first crimping joint 51 into the loading through hole 421.

[0051] Specifically, such as Figure 10 , Figure 11 As shown, the second needle sleeve feeding mechanism 6 includes a second needle sleeve circular vibrating plate 61, a second needle sleeve vibrator, a second needle sleeve feeding tube 62, and a second needle sleeve feeding member 63. The second needle sleeve circular vibrating plate 61 is fixed on the second needle sleeve vibrator. A spiral track is provided on the second needle sleeve circular vibrating plate 61. One end of the second needle sleeve feeding tube 62 is connected to the spiral track. The second needle sleeve feeding member 63 can move relative to the second needle sleeve feeding tube 62 and has at least a second needle sleeve engagement state connected to the second needle sleeve feeding tube 62 and a second needle sleeve delivery state connected to the first crimping mechanism 5. The second needle sleeve vibrator can drive the second needle sleeve circular vibrating plate 61 to vibrate vertically and torsionally around its vertical axis, so that the twisted needle in the second needle sleeve circular vibrating plate 61 rises along the spiral track and is fed into the second needle sleeve feeding tube 62. When the second needle sleeve feeding member 63 is in the second needle sleeve receiving state, the second needle sleeve in the second needle sleeve feeding tube 62 is fed into the second needle sleeve feeding member 63. When the second needle sleeve feeding member 63 is in the second needle sleeve delivery state, it docks with the second crimping mechanism 7 and feeds the second needle sleeve into the second crimping mechanism 7.

[0052] Furthermore, the second needle sleeve feeding component 63 includes a second needle sleeve feeding cylinder 631 and a second needle sleeve loading column 632. The movable end of the second needle sleeve feeding cylinder 631 is fixed to the second needle sleeve loading column 632, which can drive the second needle sleeve loading column 632 to reciprocate and switch between the second needle sleeve receiving state and the second needle sleeve dispensing state. The second needle sleeve loading column 632 is provided with a second needle sleeve through hole for loading the second needle sleeve, and the second needle sleeve through hole matches the second needle sleeve. When the second needle sleeve feeding component 63 switches to the second needle sleeve receiving state, the second needle sleeve through hole connects with the second needle sleeve conveying pipe 62, and the second needle sleeve conveying pipe 62 inputs the second needle sleeve into the second needle sleeve through hole. When the second needle sleeve feeding component 63 switches to the second needle sleeve dispensing state, the second needle sleeve through hole connects with the second crimping mechanism 7, thereby completing the feeding process of the second needle sleeve.

[0053] Specifically, such as Figure 12 , Figure 14 As shown, the manual threading mechanism 8 includes a wire harness placement platform 81, a wire harness fixing member 82, and a wire harness guide 83. The wire harness placement platform 81 is disposed on the side of the second crimping mechanism 7 away from the second needle sleeve feeding mechanism 6. The wire harness guide 83 is fixed on the wire harness placement platform 81 and fits against the second crimping mechanism 7. The wire harness fixing member 82 is slidably connected to the wire harness placement platform 81 and can move closer to or further away from the wire harness guide 83. The wire harness fixing member 82 is used to fix the wire harness to be processed and make one end of the wire harness to be processed protrude relative to the wire harness guide 83. When the wire harness fixing member 82 approaches the wire harness guide 83, the wire harness guide 83 guides the protruding end of the wire harness to be processed relative to the wire harness fixing member 82 into the second crimping mechanism 7.

[0054] Furthermore, the wire harness placement platform 81 is provided with a sliding groove 811 for accommodating the wire harness fixing member 82. The sliding groove 811 is perpendicular to the wire harness guide member 83. The wire harness fixing member 82 is embedded in the sliding groove 811 and can slide relative to the wire harness placement platform 81, moving closer to or away from the wire harness guide member 83.

[0055] Furthermore, the wire harness fixing component 82 includes a fixing base 821 and a flip cover 822. The fixing base 821 is embedded in the sliding groove 811. One side of the flip cover 822 is hinged to the fixing base 821 and can rotate relative to the fixing base 821. It has at least a covered state covering the top of the fixing base 821 and an open state exposing the top of the fixing base 821. The fixing base 821 has a fixing groove for placing the wire harness to be processed. When the flip cover 822 is in the open state, the fixing groove is exposed, making it convenient for manual placement of the wire harness to be processed into the fixing groove. When the flip cover 822 is in the covered state, the flip cover 822 cooperates with the fixing base 821 to fix the wire harness to be processed.

[0056] Furthermore, a guide hole 831 is formed on the wire harness guide 83. One end of the guide hole 831 is connected to the second crimping mechanism 7. When the wire harness fixing member 82 approaches the wire harness guide 83, it extends into the guide hole 831 from the other end. The inner diameter of the guide hole 831 gradually decreases along the direction of the wire harness fixing member 82 approaching the wire harness guide 83. The inner surface of the guide hole 831 is a conical surface. When the wire harness fixing member 82, which fixes the wire harness to be processed, extends into the guide hole 831, the conical surface of the guide hole 831 has the effect of converging the wire harness to be processed, preventing the wire harness to be processed from splitting and affecting the processing effect.

[0057] Specifically, such as Figure 10 , Figure 11 as well as Figure 13 As shown, the second crimping mechanism 7 includes a second crimping head 71 and a blowing component 72. The second crimping head 71 is fixed on the base 1 and located between the wire harness placement platform 81 and the second needle sleeve feeding component 63. One side of the second crimping head 71 is connected to the wire harness guide 83, and the other side is connected to the second needle sleeve feeding component 63. The blowing component 72 is fixed on the base 1 and can move relative to it. It has a removal station for blowing off unqualified crimped twisted needles, a first blowing station for connecting with the through hole of the second needle sleeve in the second needle sleeve feeding state, and a connection with... A second blowing station is formed between the second crimping joints 71 to accommodate the second gap of the loading head 42; when in the removal station, the blowing component 72 is used to blow off the unqualified twisted needles crimped in the loading head 42; when in the first blowing station, the blowing component 72 is used to blow the needle sleeve in the second needle sleeve through hole into the second crimping joint 71; when in the second blowing station, the blowing component 72 can dock with the loading head 42 in the second gap, and is used to blow the first needle sleeve with a twisted needle crimped at one end in the loading head 42 into the second crimping joint 71.

[0058] Furthermore, the second crimp connector 71 includes a second retaining ring 711, at least one second crimping assembly 712, and a second retaining base 713. The second crimping assembly 712 has two relatively movable crimping surfaces and is embedded in a groove in the second retaining base 713. The inner wall of the second retaining ring 711 has concave and convex surfaces corresponding to the second crimping assembly 712. When the second retaining ring 711 rotates to the point where the convex surface contacts the second crimping assembly 712, the two crimping surfaces of the second crimping assembly 712 move relative to each other, crimping the material located at the center of the second retaining ring 711. When the second retaining ring 711 rotates to the point where the concave surface contacts the second crimping assembly 712, the two crimping surfaces of the second crimping assembly 712 move away from each other, disengaging from the material located at the center of the second retaining ring 711. The second crimp connector 71 can be used to crimp a wire harness to a first needle sleeve with a twisted needle crimped to one end, or to crimp a wire harness to a second needle sleeve. In practical use, the appropriate option can be selected based on production needs.

[0059] In this embodiment, the second crimp connector 71 has two second crimping assemblies 712, the axes of which are perpendicular to each other. The two second crimping assemblies 712 can crimp the twisted needle located at the center of the second retaining ring 711 from four directions.

[0060] Furthermore, the second pressing assembly 712 includes a third pressing block, a fourth pressing block, a third elastic element, and a fourth elastic element. One end of the third elastic element and the fourth elastic element are fixed to the second fixed base 713. The third pressing block is fixed to the other end of the third elastic element, and the fourth pressing block is fixed to the other end of the fourth elastic element. When the second fixed ring 711 rotates to the point where its concave surface contacts the second pressing assembly 712, the third elastic element and the fourth elastic element can drive the third pressing block and the fourth pressing block to move in opposite directions, causing the third pressing block and the fourth pressing block to disengage from the material located at the center of the second fixed ring 711.

[0061] In practice, the servo motor drives the second fixed ring 711 to rotate, causing the second crimping assembly 712 to work. When the blowing component 72 blows in the first needle sleeve with a twisted needle crimped at one end, the two second crimping assemblies 712 work, and the third crimping block and the fourth crimping block move relative to each other, clamping the needle sleeve from four directions. When the manual threading mechanism 8 introduces the wire harness into the needle sleeve, the two second crimping assemblies 712 continue to work, and the third crimping block and the fourth crimping block move relative to each other further, squeezing the needle sleeve and crimping the wire harness together with the needle sleeve.

[0062] Furthermore, the blowing component 72 includes a vertical cylinder 721, a translation cylinder 722, and an air nozzle 723. The movable end of the vertical cylinder 721 is fixed to the translation cylinder 722, driving the translation cylinder 722 and the air nozzle 723 to move in a direction perpendicular to the second pressure joint 71. The movable end of the translation cylinder 722 is fixed to the air nozzle 723, driving the air nozzle 723 to move in a direction parallel to the second pressure joint 71. When the movable end of the vertical cylinder 721 is retracted to its minimum state and the movable end of the translation cylinder 722 is retracted to its minimum state, the blowing component 72 is in the removal station; when the movable end of the vertical cylinder 721 is retracted to its minimum state and the movable end of the translation cylinder 722 is extended to its maximum state, the blowing component 72 is in the second blowing station; when the movable end of the vertical cylinder 721 is extended to its maximum state and the movable end of the translation cylinder 722 is extended to its maximum state, the blowing component 72 is in the first blowing station.

[0063] In actual use, the crimping mode can be selected according to actual needs:

[0064] 1. Single-sided crimping mode: The first needle sleeve feeding mechanism 2 and the twisted needle feeding mechanism 3 respectively feed the first needle sleeve and the twisted needle into the first crimping mechanism 5 from both sides. The twisted needle pushing component 52 pushes the twisted needle on the twisted needle feeding component 33 into the first crimping connector 51. The first needle sleeve pushing component 53 pushes the first needle sleeve on the first needle sleeve feeding component 23 into the first crimping connector 51 and sleeves it on one end of the twisted needle. The first crimping connector 51 crimps the end of the twisted needle with the first needle sleeve sleeve sleeve on it. After the crimping is completed, the twisted needle pushing component 52 continues to move, and the pusher pin 522 pushes out the crimped twisted needle and needle sleeve in the first crimping connector 51, thereby completing the single-sided crimping operation between one end of the needle sleeve and the twisted needle.

[0065] 2. The needle sleeve double-sided crimping mode: The first needle sleeve feeding mechanism 2 and the twisted needle feeding mechanism 3 respectively feed the first needle sleeve and twisted needle into the first crimping mechanism 5 from both sides. The twisted needle pushing component 52 pushes the twisted needle on the twisted needle feeder 33 into the first crimping connector 51. The first needle sleeve pushing component 53 pushes the first needle sleeve on the first needle sleeve feeder 23 into the first crimping connector 51 and fits it onto one end of the twisted needle. The first crimping connector 51 crimps the end of the twisted needle with the first needle sleeve fitted on it. After crimping is completed, the robotic arm 41 drives the loading head 42 to move to the first crimping connector 51 and mates with it. The twisted needle pushing component... 52 continues to move, the ejector pin 522 pushes the crimped twisted needle and the first needle sleeve in the first crimping head 51 into the loading head 42, the loading head 42 is reversed under the drive of the robotic arm 41 and docks with the second crimping mechanism 7, so that the un-crimped end of the first needle sleeve faces the second crimping mechanism 7, the blowing component 72 blows air into the loading through hole 421, so that the twisted needle and the first needle sleeve enter the second crimping mechanism 7, and the manual threading mechanism 8 feeds the wire bundle to be processed into the other side of the second crimping mechanism 7, the wire bundle to be processed and the end of the first needle sleeve away from the twisted needle are threaded together, and the second crimping mechanism 7 crimps the first needle sleeve and the wire bundle to be processed.

[0066] 3. Single-sided crimping mode of wire harness: The wire harness to be processed is manually fed into the other side of the second crimping mechanism 7 through the manual threading mechanism 8. The second needle sleeve feeding mechanism 6 feeds the second needle sleeve into the second crimping mechanism 7 from the other side. The blowing component 72 blows air into the second needle sleeve loading column 632 to send the second needle sleeve in the through hole of the second needle sleeve into the second crimping connector 71 and puts it on one end of the wire harness to be processed. The second crimping connector 71 crimps the second needle sleeve and the wire harness to be processed.

[0067] The beneficial effects of this invention are as follows: This invention provides a multi-mode crimping device, including a base, a first needle sleeve feeding mechanism, a twisted needle feeding mechanism, a robotic arm carrying mechanism, a first crimping mechanism, a second needle sleeve feeding mechanism, a second crimping mechanism, and a manual threading mechanism. These mechanisms cooperate with each other to achieve multiple crimping modes. Only one device is needed to realize three processing methods: crimping twisted needles to needle sleeves, crimping twisted needles and wire harnesses to needle sleeves, and crimping wire harnesses to needle sleeves, producing corresponding products to meet different production needs while effectively reducing production costs.

[0068] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
