Description

Technical Field

[0001] The present invention relates to the technical field of wire processing, and in particular to a wire terminal crimping device. Background Art

[0002] like Figure 1 and Figure 2 As shown, the existing technology for crimping a metal terminal onto a wire comprises the following steps: stripping the insulation layer at one end of the wire to expose the internal conductor, and then inserting the exposed conductor portion into the terminal. After the conductor enters the terminal, the terminal is induction heated. When the terminal reaches a certain temperature, its strength decreases. At this time, the terminal is extruded and shaped by a mold, and the terminal is crimped after it cools down.

[0003] However, the manufacturer discovered the following problems during the actual production process: after the insulation layer at the end of the wire is stripped off, the metal wire that constitutes the conductor inside will no longer be constrained by the insulation layer. In the process of transporting the wire to the inside of the terminal, the metal wire that constitutes the conductor will diverge to a certain extent due to factors such as vibration and air flow. After the metal wire diverges, the radius of the conductor end face will increase. In the process of inserting the conductor into the terminal, the metal wire located on the outer ring of the conductor may not be inserted into the terminal, affecting the crimping quality of the product.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1 and Figure 2A wire terminal pressing device includes a driving rail 1, a plurality of connecting rods 2 are fixedly connected to the top of the driving rail 1 at equal intervals, side baffles 10 are horizontally fixedly connected to the bottom of both sides of the connecting rod 2, one side of the side baffle 10 is fixedly connected to an extrusion mechanism for clamping and shaping the terminal, and the other side of the side baffle 10 is slidably fitted with a movable plate 4, the extrusion mechanism includes a connecting plate 12, the connecting plate 12 is fixed to the side baffle 10, an induction heating coil 13 is fixedly connected to the middle of the connecting plate 12, and a clamping cylinder 14 is vertically fixed to the upper and lower sides of the connecting plate 12, and the output end of the clamping cylinder 14 is fixedly connected to the mold 15.

[0033] The mold 15 includes an upper mold and a lower mold, and the upper mold and the lower mold are respectively fixed on two clamping cylinders 14. During operation, the terminal is placed between the upper mold and the lower mold, and the clamping cylinder 14 drives the upper mold and the lower mold to approach each other so that the upper mold and the lower mold clamp and fix the terminal. After the terminal is fixed by the mold 15, the exposed conductor part of the wire is inserted into the terminal, and then the terminal is heated by the induction heating coil 13. The strength of the terminal decreases after heating. At this time, the mold 15 is driven to close by the clamping cylinder 14. Under the extrusion of the upper mold and the lower mold, the terminal will be fixed on the exposed conductor of the wire, thereby completing the crimping work of the terminal.

[0034] like Figure 3-Figure 7 As shown, the top of the movable plate 4 is fixed with a sliding seat 3, the driving track 1 and the sliding seat 3 slide together to drive the sliding seat 3 to move horizontally, a through hole is opened in the middle of the movable plate 4 to accommodate the passage of the wire, and a circular rotating seat 16 is installed on one side of the movable plate 4. A locking structure is provided on the other side of the movable plate 4 to lock the wire. The locking structure includes a motor 9 and a plate 5 made of elastic material. The plate 5 is spirally wound into a trumpet shape, and an arc-shaped clamp 7 is sleeved on the end of the plate 5. Both ends of the clamp 7 are fixed. There is a nut seat 8, the nut seat 8 is threadedly fitted on the bidirectional screw 6, the motor 9 is fixed to the outer wall of the movable plate 4, the output end of the motor 9 is coaxially fixed to the bidirectional screw 6, and two guide grooves 17 on the end face of the rotating seat 16 are provided. There are sliders 21 slidingly fitted in the two guide grooves 17, one of the sliders 21 is fixed with an inverted V-shaped upper clamping block 22, and the other slider 21 is fixed with a V-shaped lower clamping block 23. The upper clamping block 22 and the lower clamping block 23 are slidably fitted to clamp the wire.

[0035] During the crimping operation, the conductor portion of the wire passes through the through hole and moves toward the terminal clamped by the mold 15. When the head of the conductor enters between the upper clamping block 22 and the lower clamping block 23, the driving track 1 drives the sliding seat 3 to approach the terminal, and the movable plate 4 at the bottom of the sliding seat 3 also approaches the terminal, and the moving speed of the movable plate 4 is the same as the moving speed of the wire, so that the wire and the movable plate 4 remain in a relatively static state.

[0036] As the wire and the movable plate 4 remain relatively stationary and approach the terminal, the motor 9 is started, and the motor 9 drives the bidirectional screw 6 to rotate. During the rotation of the bidirectional screw 6, the two nut seats 8 are driven to approach each other. The approach of the two nut seats 8 to each other will cause the clamp 7 to shrink. After the clamp 7 shrinks, the inner diameter of the spirally wound plate 5 will shrink, so that the plate 5 tightens the middle part of the conductor.

[0037] After the plate 5 tightens the middle part of the conductor, the upper clamping block 22 and the lower clamping block 23 are moved closer to each other to clamp the head of the conductor.

[0038] like Figures 6-10 As shown, a transmission structure is provided on both sides of the movable plate 4 to drive the rotating seat 16 to rotate, and the transmission structure includes two fixed plates 27, which are fixedly connected to both sides of the movable plate 4, and a slide groove 28 is provided on the fixed plate 27. A mounting block 29 is slidably fitted in the slide groove 28, and a rotating shaft 30 is rotatably installed on the surface of the mounting block 29. A first pulley 37 is coaxially fixed to the surface of the rotating shaft 30, and a bearing seat 19 is fixed to the bottom of the movable plate 4. A worm 20 is rotatably installed in the bearing seat 19, and a worm wheel 18 is coaxially fixed to the outer wall of the rotating seat 16. The worm 20 cooperates with the worm wheel 18, and a second pulley 38 is installed at both ends of the worm 20. A belt 39 is installed on the first pulley 37 and the second pulley 38.

[0039] When the rotating shaft 30 rotates, the rotating shaft 30 will drive the first pulley 37 to rotate. The rotation of the first pulley 37 will drive the second pulley 38 to rotate through the belt 39. The rotation of the second pulley 38 will drive the worm 20 to rotate. The rotation of the worm 20 will drive the worm wheel 18 to rotate. The rotation of the worm wheel 18 will drive the rotating seat 16 to rotate synchronously. During the rotation of the rotating seat 16, the upper clamping block 22 and the lower clamping block 23 will be driven to rotate synchronously. Since the upper clamping block 22 and the lower clamping block 23 clamp the head of the conductor at this time, the head of the conductor will rotate during the rotation of the upper clamping block 22 and the lower clamping block 23, so that the head of the conductor is spirally wound, and since the middle part of the conductor is tightened by the plate 5, the spirally wound conductor will not pass over the plate 5, thereby preventing the tail of the conductor and the wire connected to the tail from rotating.

[0040] like Figure 8 and Figure 10 As shown, a tensioning structure is provided on the fixed plate 27 to keep the belt 39 in a tensioned state. The tensioning structure includes a guide block 34. A groove 33 is horizontally opened at the bottom of the fixed plate 27. The guide block 34 slides in the groove 33. A tension spring 35 is provided in the groove 33 to apply tension to the guide block 34. A tensioning wheel 36 is rotatably installed on the surface of the guide block 34, and the tensioning wheel 36 rests on the belt 39.

[0041] Under the elastic tension of the tension spring 35 on the guide block 34, the tensioning wheel 36 can always be in close contact with the belt 39 and exert a certain force on the belt 39, thereby ensuring that the belt 39 is always in a tensioned state.

[0042] like Figure 14-16 As shown, a slot 42 is provided through the middle of the side baffle 10, and a parallelogram-shaped limit plate 11 is provided in the middle of the slot 42. The limit plate 11 is fixed to the bottom of the connecting rod 2, and the end of the rotating shaft 30 is coaxially fixed with a driven gear 32. The driven gear 32 slides between the outer wall of the limit plate 11 and the inner wall of the slot 42. A first rack 40 is fixed to the bottom surface of the slot 42, and a second rack 41 is fixed to the top of the limit plate 11. Both the first rack 40 and the second rack 41 cooperate with the driven gear 32.

[0043] like Figure 15 As shown, the limiting plate 11 is located in the middle part of the slot 42 , and the limiting plate 11 separates the slot 42 into four parts a, b, c and d, and the driven gear 32 circulates in the four parts a, b, c and d.

[0044] like Figures 9-11 As shown, a driving structure is provided on the fixed plate 27 to drive the upper clamping block 22 and the lower clamping block 23 to clamp the wire. The driving structure includes a brake wire tube 24 that cannot be axially deformed. One end of the brake wire tube 24 is fixed to the top of the upper clamping block 22, and the other end is fixed to the top of the fixed plate 27. A brake wire 25 is slidably fitted in the brake wire tube 24. Both ends of the brake wire 25 extend from the brake wire tube 24 to the outside. One end of the brake wire 25 passes through the upper clamping block 22 and is fixed to the bottom of the lower clamping block 23. The other end of the brake wire 25 is fixed to the outer wall of the rotating tube 31. The rotating tube 31 is sleeved on the rotating shaft 30. The brake wire 25 located between the upper clamping block 22 and the lower clamping block 23 is sleeved with a compression spring 26 that is always in a compressed state.

[0045] like Figure 16 As shown, when the movable plate 4 and the wire rod are moving toward the terminal together, the driven gear 32 will also move toward the terminal together, corresponding to Figure 16 In the middle, the driven gear 32 moves from right to left. During the movement of the driven gear 32 from right to left:

[0046] The driven gear 32 will first move down from part a to part b. During this process, the driven gear 32 will drive the mounting block 29 to move down in the chute 28 through the rotating shaft 30. The downward movement of the rotating shaft 30 will drive the rotating tube 31 to move down. Figure 11 As shown, the downward movement of the rotating tube 31 will apply a pulling force from one end of the brake line 25. Under the pulling force of the brake line 25, the distance between the lower clamping block 23 and the upper clamping block 22 will decrease, so that the lower clamping block 23 and the upper clamping block 22 can clamp the head of the conductor while compressing the compression spring 26.

[0047] As the driven gear 32 continues to move to the left, the driven gear 32 will move from right to left in part b. During the process of the driven gear 32 moving to the left in part b, the first rack 40 will drive the driven gear 32 to rotate. The rotation of the driven gear 32 will drive the rotating shaft 30 to rotate, thereby driving the rotating seat 16 to rotate through the transmission structure, so that the head of the conductor is spirally wound.

[0048] When the driven gear 32 moves to the leftmost end in part b, the distance between the lower clamping block 23 and the upper clamping block 22 will increase under the elastic force of the compression spring 26. At this time, the lower clamping block 23 and the upper clamping block 22 no longer clamp the head of the conductor, and in the process of increasing the distance, the lower clamping block 23 will apply a pulling force to the brake line 25. Under the pulling force of the brake line 25, the rotating tube 31 will move upward. The upward movement of the rotating tube 31 will drive the driven gear 32 to move upward through the rotating shaft 30, so that the driven gear 32 moves from part b to part c.

[0049] When the driven gear 32 is located in part c, the motor 9 drives the bidirectional screw 6 to reverse to reset the two nut seats 8. After the nut seats 8 are reset, the plate 5 and the clamp 7 will also be reset under the action of their own elastic force, so that the plate 5 no longer locks the conductor.

[0050] When the driven gear 32 is located in part c and the lower clamping block 23, the upper clamping block 22 and the plate 5 are reset, the wire will continue to move until the conductor enters the terminal, and the driving track 1 will drive the sliding seat 3 to move from left to right for reset. During the reset of the sliding seat 3, the driven gear 32 will enter part d from part c. When the driven gear 32 moves to the right in part d, the second rack 41 will drive the driven gear 32 to reverse, thereby causing the rotating seat 16 to reverse for reset. When the driven gear 32 moves to the right to the rightmost end in part d, the driven gear 32 will re-enter part a for reset under the action of gravity.

[0051] Working principle and workflow:

[0052] like Figure 12 and Figure 13 As shown, during the crimping work, the conductor part of the wire passes through the through hole and moves toward the terminal clamped by the mold 15. When the head of the conductor enters between the upper clamping block 22 and the lower clamping block 23, the driving track 1 drives the sliding seat 3 to approach the terminal, and the movable plate 4 at the bottom of the sliding seat 3 also approaches the terminal, and the moving speed of the movable plate 4 is the same as the moving speed of the wire, so that the wire and the movable plate 4 remain in a relatively static state.

[0053] As the wire and the movable plate 4 remain relatively stationary and approach the terminal, the motor 9 is started, and the motor 9 drives the bidirectional screw 6 to rotate. During the rotation of the bidirectional screw 6, the two nut seats 8 are driven to approach each other. The approach of the two nut seats 8 to each other will cause the clamp 7 to shrink. After the clamp 7 shrinks, the inner diameter of the spirally wound plate 5 will shrink, so that the plate 5 tightens the middle part of the conductor.

[0054] like Figure 16 As shown, when the movable plate 4 and the wire rod are moving toward the terminal together, the driven gear 32 will also move toward the terminal together, corresponding to Figure 16 In the middle, the driven gear 32 moves from right to left. During the movement of the driven gear 32 from right to left:

[0055] The driven gear 32 will first move down from part a to part b. During this process, the driven gear 32 will drive the mounting block 29 to move down in the chute 28 through the rotating shaft 30. The downward movement of the rotating shaft 30 will drive the rotating tube 31 to move down. Figure 11 As shown, the downward movement of the rotating tube 31 will apply a pulling force from one end of the brake line 25. Under the pulling force of the brake line 25, the distance between the lower clamping block 23 and the upper clamping block 22 will decrease, so that the lower clamping block 23 and the upper clamping block 22 can clamp the head of the conductor while compressing the compression spring 26.

[0056] As the driven gear 32 continues to move to the left, the driven gear 32 will move from right to left in part b. During the movement of the driven gear 32 to the left in part b, the first rack 40 will drive the driven gear 32 to rotate. The rotation of the driven gear 32 will drive the rotating shaft 30 to rotate. During the rotation of the rotating shaft 30, the rotating shaft 30 will drive the first pulley 37 to rotate. The rotation of the first pulley 37 will drive the second pulley 38 to rotate through the belt 39. The rotation of the second pulley 38 will drive the worm 20 to rotate. The rotation of the worm 20 will drive the worm gear 18 rotates, and the rotation of the worm gear 18 will drive the rotating base 16 to rotate synchronously. During the rotation of the rotating base 16, the upper clamping block 22 and the lower clamping block 23 will be driven to rotate synchronously. Since the upper clamping block 22 and the lower clamping block 23 clamp the head of the conductor at this time, the head of the conductor will rotate during the rotation of the upper clamping block 22 and the lower clamping block 23, so that the head of the conductor is spirally wound, and since the middle part of the conductor is clamped by the plate 5, the spirally wound conductor will not go over the plate 5, thereby preventing the tail of the conductor and the wire connected to the tail from rotating.

[0057] When the driven gear 32 moves to the leftmost end in part b, the distance between the lower clamping block 23 and the upper clamping block 22 will increase under the elastic force of the compression spring 26. At this time, the lower clamping block 23 and the upper clamping block 22 no longer clamp the head of the conductor, and in the process of increasing the distance, the lower clamping block 23 will apply a pulling force to the brake line 25. Under the pulling force of the brake line 25, the rotating tube 31 will move upward. The upward movement of the rotating tube 31 will drive the driven gear 32 to move upward through the rotating shaft 30, so that the driven gear 32 moves from part b to part c.

[0058] When the driven gear 32 is located in part c, the motor 9 drives the bidirectional screw 6 to reverse to reset the two nut seats 8. After the nut seats 8 are reset, the plate 5 and the clamp 7 will also be reset under the action of their own elastic force, so that the plate 5 no longer locks the conductor.

[0059] When the driven gear 32 is located in part c and the lower clamping block 23, the upper clamping block 22 and the plate 5 are reset, the wire will continue to move until the conductor enters the terminal, and the driving track 1 will drive the sliding seat 3 to move from left to right for reset. During the reset of the sliding seat 3, the driven gear 32 will enter part d from part c. When the driven gear 32 moves to the right in part d, the second rack 41 will drive the driven gear 32 to reverse, thereby causing the rotating seat 16 to reverse for reset. When the driven gear 32 moves to the right to the rightmost end in part d, the driven gear 32 will re-enter part a for reset under the action of gravity.

[0060] like Figure 17 As shown, before the wire enters the terminal, the head of the conductor on the wire is spirally wound, and the multiple metal wires that constitute the conductor are wound around each other to prevent the metal wires in the outer ring from diverging to the surroundings, ensuring that the conductor can completely enter the terminal.

[0061] After the conductor enters the terminal, the induction heating coil 13 is energized to heat the terminal. After heating, the strength of the terminal decreases. At this time, the clamping cylinder 14 drives the mold 15 to close the mold. Under the extrusion of the upper and lower molds, the terminal will be fixed on the exposed conductor of the wire, thereby completing the crimping work of the terminal.

[0062] Compared with the prior art, the wire terminal crimping device provided by the present invention clamps the exposed conductor part of the wire through the upper clamping block 22 and the lower clamping block 23 during the process of crimping the terminal onto the wire, and the conductor head is spirally wound by the rotation of the upper clamping block 22 and the lower clamping block 23. The entangled conductors will be constrained in the radial direction to prevent the metal wire constituting the conductor from diverging radially, thereby ensuring that the conductor can smoothly and completely enter the terminal, thereby achieving the purpose of improving the terminal crimping quality.

[0063] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
