Description
Technical Field
[0001] This invention relates to the field of wire harness crimping technology, specifically to a wire harness metal end crimping device for EMB wire harness production. Background Technology
[0002] EMB harnesses refer to electrical connection harness assemblies used in electromechanical braking systems. Harness crimping is a key process in EMB harness production, designed to achieve a tight connection between wires and terminals through pressure forming, thereby providing an inseparable, long-term reliable electrical and mechanical connection. Its main purpose is to ensure the stability of signal transmission and power distribution, thus guaranteeing the normal operation of the entire electrical system.
[0003] Currently, in the EMB wire harness crimping process, the insulation layer at the end of the wire harness is first removed using wire strippers to expose the metal wires. Then, metal terminals are inserted onto the metal wires, and finally, a crimping mechanism is used to press the wires and metal terminals together. However, during crimping, the metal wires are prone to unraveling, preventing the metal terminals from fully fitting onto the wires and affecting the crimping quality. The unraveled wires need to be manually tightened to reduce unraveling, making the wire harness crimping process cumbersome, time-consuming, and labor-intensive, significantly reducing the efficiency of wire harness crimping. Summary of the Invention

[0016] The present invention has the following beneficial effects:
[0017] 1. In this EMB wire harness metal end crimping equipment, the wire harness to be crimped can be clamped by the first gripper on the base plate. The horizontal movement position of the second gripper can be adjusted by the first electric push rod, so that the second gripper moves closer to the end of the wire harness for clamping. The cutter holder on the gripper finger of the second gripper facilitates the storage of the cutter, reducing the contact between the cutter and other objects when not in use and improving the protection effect. The cutter can remove the insulation layer of the wire harness. The slot opened on the crimping seat can be used to place the metal terminal. When the feeding guide is aligned with the slot of the crimping seat, the metal terminal can fall from the feeding guide into the slot, improving the convenience of feeding the metal terminal. The angle of the crimping seat can be adjusted by the first servo motor, so that the metal terminal can be aligned with the metal wire when inserted into the end of the wire harness, facilitating the precise insertion of the metal terminal. By adjusting the position of the two crimping blocks, the wire harness and the metal terminal can be crimped.
[0018] The first electric push rod drives the second gripper to approach the wire harness. During the movement, the first abutment bar abuts against the end face of the first gripper, causing the first abutment bar to move relative to the first gripper, which causes the cutter to extend from the cutter holder. When the gripping fingers of the second gripper approach each other, they can cut and clamp the insulation layer of the wire harness. Through the cooperation of the second servo motor, the first electric push rod, and the first clamping block, the cut insulation layer can be driven to rotate and retract on the wire harness. On the one hand, the cut insulation layer can be quickly peeled off from the wire harness. On the other hand, the insulation layer can tighten the wire harness wires during rotation, improving the wire tightness and reducing the occurrence of wire fraying, which facilitates the insertion of metal terminals. The first servo motor can adjust the angle between the second gripper and the crimping seat, so that the metal terminal engaged on the crimping seat can be automatically aligned with the metal wire when inserted. Through the cooperation of the second electric push rod and the crimping block, the metal terminal can be firmly pressed onto the metal wire at the end of the wire harness. During the wire harness crimping process, manual operation steps are reduced, saving time and effort, and making it convenient and fast, which can improve the crimping efficiency of the wire harness and the metal terminal.
[0019] 2. In this EMB wire harness metal end crimping equipment, the cleaning brush that slides inside the arc-shaped slider can contact the wire harness surface. During the horizontal movement of the second gripper, impurities on the wire harness surface can be cleaned, reducing hard impurities at the cutting edge of the cutter, which helps protect the blade of the cutter and thus extends its service life. The second clamping block on the crimping seat can clamp the metal terminal, preventing the metal terminal from detaching from the crimping seat when it rotates.
[0020] When the second gripper moves horizontally, it causes the first contact bar to contact the first gripper, which in turn causes several first contact wedges on the first contact bar to intermittently contact the second contact rod. This allows the rocker plate to continuously drive the cleaning brush to slide on the arc-shaped slider, enabling the cleaning brush to reciprocate and clean the wire harness surface, reducing cleaning dead angles and improving the cleaning effect. When the crimping seat moves horizontally synchronously, it causes the first contact frame to contact the feeding guide tube, which increases the clamping distance between the two second gripping blocks. When the feeding guide tube is aligned with the slot of the crimping seat, the metal terminal can automatically fall into the crimping seat, thus completing the feeding.
[0021] 3. In the wire harness metal end crimping equipment for EMB wire harness production, the limiting blocks set on both sides below the feeding guide can limit the metal terminals in the feeding guide, preventing the metal terminals from falling out of the feeding guide and affecting the convenience of feeding.
[0022] To improve the accuracy of metal terminal feeding, after the piston rod of the first electric push rod pushes the first abutment strip on the second gripper to abut against the first gripper, the piston rod continues to extend, causing the second abutment strip to abut against the conical abutment block, causing the crimping seat to move upward and closer to the lower end of the feeding guide tube, thereby reducing the feeding height difference and improving the feeding accuracy. At the same time, during the upward movement, the first abutment frame and the second abutment frame can abut against each other, thereby releasing the limiting block from restricting the metal terminal in the feeding guide tube, so that the metal terminal automatically falls into the crimping seat.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] Example 1, please refer to Figures 1 to 12 A wire harness metal end crimping device for EMB wire harness production includes a base plate 1, on which a first gripper 2 and a mounting base 3 are respectively installed. A first electric push rod 4 is fixed on the mounting base 3. A mounting frame 5 is connected to the piston rod of the first electric push rod 4. A first servo motor 6 is fixed on the mounting frame 5. A mounting block 7 is installed on the motor shaft of the first servo motor 6. A crimping seat 9 and a rotatable second gripper 8 are installed on the mounting block 7. Two symmetrical crimping blocks 10 are provided inside the crimping seat 9.
[0038] A blade holder 11 is fixed on the gripper finger of the second gripper 8. A movable cutter 12 is provided inside the blade holder 11. A slidable cleaning brush 13 is provided on one side of the blade holder 11. A first abutment strip 14 is slidably connected on the gripper finger of the second gripper 8. A feeding guide tube 35 is provided above the base plate 1.
[0039] A second servo motor 15 is fixed on the mounting block 7. The motor shaft of the second servo motor 15 is fixedly connected to the second gripper 8. A first clamping block 16 is fixed on the gripping finger of the second gripper 8. A slot 91 is provided on the crimping seat 9. The crimping block 10 is located in the slot 91. A second electric push rod 25 is fixed on the crimping seat 9. The crimping block 10 is fixedly connected to the piston rod of the second electric push rod 25.
[0040] One end of the cutter 12 is fixed with a first abutting rod 17. The first abutting rod 17 is elastically connected to the gripping fingers of the second gripper 8 through a first spring 18. A second spring 19 is connected between the first abutting bar 14 and the gripping fingers of the second gripper 8.
[0041] An arc-shaped slider 20 is fixed on the blade holder 11. A groove 21 is provided on the arc-shaped slider 20. A sliding rod 22 and a strip block 24 are fixed on the cleaning brush 13 respectively. The sliding rod 22 is slidably connected in the groove 21, and a third spring 23 is connected between the sliding rod 22 and the arc-shaped slider 20.
[0042] The second gripper 8 has a rotating shaft 26 installed on its gripping fingers. A rocker 27 is fixed on the rotating shaft 26. One end of the rocker 27 abuts against the strip block 24, and the other end of the rocker 27 is fixed with a second abutting rod 28. Several first abutting wedges 29 are fixed on the first abutting strip 14.
[0043] refer to Figures 1 to 12During wire harness crimping, the wire harness is first clamped by the first jaw 2 on the base plate 1, leaving a certain crimping length. The first electric push rod 4 on the mounting base 3 drives the mounting bracket 5 to move horizontally, causing the second jaw 8 to approach the end of the wire harness, so that the cleaning brush 13 is located on both sides of the wire harness. At the same time, the distance between the two gripping fingers of the second jaw 8 is adjusted so that the cleaning brush 13 is in contact with the surface of the wire harness. During the movement, the cleaning brush 13 can clean the impurities on the surface of the wire harness, reducing hard impurities at the cutting point of the cutter 12, which helps protect the blade of the cutter 12 and thus extends its service life. At the same time, the first abutment strip 14 slidably connected to the gripping fingers of the second jaw 8 abuts against the gripping fingers of the first jaw 2 during the movement, so that the first abutment strip 14 drives several first abutment wedges 29 on the second jaw 8. The inner side of the finger clamp moves, and the second spring 19 stores force, which can achieve the purpose of intermittent contact between several first contact wedges 29 and second contact rods 28, causing the rocker 27 to continuously deflect on the rotating shaft 26, driving the strip block 24 to reciprocate on the arc slider 20, so that the two cleaning brushes 13 reciprocate on the arc slider 20. The third spring 23 continuously stores and releases force. The two sets of first contact wedges 29 are in opposite directions, and the contact positions of the two rocker 27 and strip block 24 are different, so that the two cleaning brushes 13 deflect in the same direction, which increases the cleaning range of the cleaning brushes 13 on the wire surface, reduces cleaning dead angles, and thus improves the cleaning effect. At the same time, the slide rod 22 slides in the slide groove 21, which can limit the movement trajectory of the cleaning brushes 13 and improve the stability of the movement of the cleaning brushes 13.
[0044] When the first abutment bar 14 moves inside the gripping fingers of the second gripper 8, it can abut against the first abutment rod 17, causing the first abutment rod 17 to automatically extend the cutter 12 from the cutter holder 11. The first spring 18 stores force. After the second gripper 8 moves into position, the second gripper 8 continues to adjust the position of the two gripping fingers, so that the cutter 12 cuts the insulation layer of the wire harness. At the same time, the first clamping block 16 firmly clamps the cut wire harness insulation layer. At this time, the crimping seat 9 moves directly below the feeding guide tube 35, and the metal terminal follows the... The feeding guide tube 35 falls into the slot 91 to complete the feeding. The first electric push rod 4 drives the mounting bracket 5 to perform initial reset. At the same time, the second servo motor 15 on the mounting block 7 drives the second gripper 8 to rotate, so that the cut insulation layer rotates and retracts on the wire harness. On the one hand, the cut insulation layer can be quickly peeled off from the wire harness. On the other hand, the insulation layer can tighten the wire harness metal wires during the rotation process, improve the tightness of the metal wires, and avoid the metal wires in the metal terminal from becoming loose, which would affect the crimping quality.
[0045] After the piston rod of the first electric push rod 4 is reset, the first servo motor 6 drives the mounting block 7 to rotate, causing the second gripper 8 and the crimping seat 9 to rotate synchronously. The base plate 1 has a rectangular slot to prevent the second gripper 8 from colliding with the base plate 1 when it rotates. After the crimping seat 9 rotates, the metal terminal in the slot 91 is aligned with the metal wire. The first electric push rod 4 drives the mounting bracket 5 to move horizontally again, so that the metal terminal is accurately inserted into the wire harness. The head of the metal terminal is used to fit on the insulation layer of the wire harness, and the metal wire is inserted into the metal terminal. The two second electric push rods 25 on the crimping seat 9 drive the two crimping blocks 10 to move towards each other, squeezing the metal terminal so that the metal wire can be tightly connected to the metal terminal.
[0046] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 12 The crimping seat 9 is provided with a second clamping block 30. A first guide rod 31 and a second abutting wedge 32 are fixed on the second clamping block 30. The first guide rod 31 is elastically connected to the crimping seat 9 through a fourth spring 33. A first abutting frame 34 abuts on the second abutting wedge 32. The first abutting frame 34 is slidably connected to the crimping seat 9.
[0047] Two limiting blocks 36 are provided below the feeding conduit 35. A sliding bracket 37 is connected to the limiting block 36. The sliding bracket 37 is elastically connected to the feeding conduit 35 through a fifth spring 38. A second abutting bracket 39 is abutted on the sliding bracket 37. The second abutting bracket 39 is slidably connected to the feeding conduit 35.
[0048] Mounting bracket 5 is elastically connected to the piston rod of the first electric push rod 4 via the sixth spring 40. A telescopic column 41 is fixed on the mounting block 7. The upper end of the telescopic column 41 is fixedly connected to the crimping seat 9. A conical abutment block 42 is fixed on one side of the crimping seat 9. A second abutment strip 43 is fixed to the end of the piston rod of the first electric push rod 4.
[0049] The mounting bracket 5 is fixed with a second guide rod 44, which is slidably connected to the mounting base 3. The base plate 1 is fixed with a support base 47, and the feeding guide tube 35 is fixed on the support base 47.
[0050] refer to Figures 1 to 11 The second clamping block 30 on the crimping seat 9 can clamp the metal terminal, thereby preventing the metal terminal from coming off the crimping seat 9 when the crimping seat 9 rotates. In order to increase the feeding speed of the metal terminal, a metal terminal will be put into the feeding guide 35 in advance. The feeding guide 35 is limited by the limiting block 36 to prevent the metal terminal from falling off.
[0051] When the metal terminal is fed, the crimping seat 9 moves horizontally, causing the first contact frame 34 to contact the feeding guide 35. The first contact frame 34 moves downwards due to the contact and contacts the second contact wedge 32 on the second clamping block 30, causing the first guide rod 31 to slide on the crimping seat 9. The fourth spring 33 stores force, increasing the clamping distance between the two second clamping blocks 30 to prevent the metal terminal from being obstructed when falling into the slot 91 of the crimping seat 9. When the slot 91 aligns with the feeding guide 35, the upper end of the first contact frame 34 contacts the lower end of the second contact frame 39. At this time, the piston rod of the first electric push rod 4 continues to move, causing the mounting bracket 5 to slide on the piston rod of the first electric push rod 4. The mounting bracket 5 remains stationary. The sixth spring 40 stores force, fixing the end of the piston rod of the first electric push rod 4. The second contact strip 43 abuts against the conical contact block 42 of the crimping seat 9. With the cooperation of the telescopic column 41, the crimping seat 9 moves upward. On the one hand, this reduces the height difference of the material feeding and improves the accuracy of the feeding. On the other hand, the upward movement of the crimping seat 9 can drive the first contact frame 34 to push the second contact frame 39 to slide on the feeding guide tube 35. The lower end of the second contact frame 39 is flush with the lower end surface of the feeding guide tube 35, so that the second contact frame 39 abuts against the sliding bracket 37. This can drive the two limit blocks 36 to move in the opposite direction. The fifth spring 38 stores force. At this time, the metal terminal in the feeding guide tube 35 is released from the limit and can automatically fall into the slot 91 of the crimping seat 9. When the crimping seat 9 moves away from the feeding guide tube 35, the first contact frame 34 resets, which can realize the purpose of the second clamping block 30 to automatically clamp the metal terminal.
[0052] The telescopic column 41 includes a hollow column, an adjusting column, and a spring. The lower end of the hollow column is fixed to the mounting block 7, the upper end of the adjusting column is fixedly connected to the pressing seat 9, and the lower end of the adjusting column is elastically connected to the hollow column through the spring.
[0053] The second guide rod 44, which is fixed on the mounting bracket 5, can slide on the mounting base 3, thereby improving the stability of the horizontal movement of the mounting bracket 5.
[0054] Example 3 is an improvement upon Example 2. For details, please refer to [link / reference]. Figures 1 to 12 This application also provides a technical solution for automatic feeding of metal terminals. A third electric push rod 45 is fixed on the base plate 1. The piston rod of the third electric push rod 45 is fixedly connected to the feeding guide tube 35. A seventh spring 46 is connected between the second contact frame 39 and the feeding guide tube 35.
[0055] refer to Figure 3 and Figure 8The piston rod of the first electric push rod 4 drives the pressing seat 9 to move directly below the feeding guide 35. The third electric push rod 45, fixed on the base plate 1, drives the feeding guide 35 downwards. The lower end of the second abutment frame 39 has an integral extension that protrudes from the lower end face of the feeding guide 35. The elastic force of the seventh spring 46 is greater than that of the fourth spring 33, causing the lower end of the second abutment frame 39 to abut against the first abutment frame 34 when it moves downwards. The second abutment wedge... When block 32 is resisted, it retracts into the crimping seat 9, which increases the distance between the two second clamping blocks 30. When the first contact frame 34 stops moving, the feeding guide 35 continues to move downward, which increases the resistance force on the second contact frame 39, causing the second contact frame 39 to slide on the feeding guide 35 and come into contact with the sliding bracket 37. This can drive the two limit blocks 36 to move in the opposite direction, release the limit on the metal terminal, and allow the metal terminal to automatically fall into the slot 91 of the crimping seat 9.
