Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile wire harness processing equipment, in particular to a full-automatic wire breaking and crimping integrated equipment for automobile wire harness processing and a processing technology. BACKGROUND

[0002] In the field of manufacturing automobile electrical systems, the full-automatic wire breaking and crimping integrated equipment for automobile wire harness processing is the core equipment for realizing efficient and accurate connection of wires and terminals. The equipment aims to automatically process scattered raw materials into complete wire harness assemblies. The core process starts with a wire stripping machine, which is responsible for accurately stripping the insulating sheath of the cable end to expose the internal metal conductor. After completing the end peeling, the wire can be automatically cut to a predetermined length. Then, the equipment moves the processed wire harness to a terminal crimping machine. The mechanism uses a special mold to apply a large mechanical pressure to the terminal from the transmission belt, making it firmly bite on the exposed conductor at the end of the wire harness. Through this crimping process, the current is stably conducted between the wire harness and the terminal, forming a reliable electrical connection loop. The entire process from stripping, cutting to crimping is continuously completed on one equipment, greatly improving production efficiency and consistency.

[0003] However, in existing technical practices, even with the use of automated equipment, the quality of wire harness processing still has the following problems: when the wire stripping machine strips the insulating sheath, its mechanical action sometimes causes unnecessary bending of the exposed copper wire, or causes deformation of the entire wire harness shape. This small deformation often appears as a slight gap between the terminal and the wire harness insulation layer after crimping, which not only affects the appearance, but also may weaken the mechanical strength of the connection, posing a hidden danger to the long-term stable use of the wire harness. In addition, the wire stripping process may also cause individual thin copper wires to be raised or offset from the original neat bundle structure, forming a misalignment. When these not-so-straight copper wires try to insert into the precise insertion hole of the terminal, they will encounter resistance and cannot be fully in place, resulting in reduced contact area and increased connection impedance. These defects ultimately affect the reliability of electrical connection and driving safety. Therefore, the present application proposes a full-automatic wire breaking and crimping integrated equipment for automobile wire harness processing and a processing technology to solve the above problems. SUMMARY

[0007] Preferably, the end of the driven plate away from the limiting block is fixedly connected with a fixed rod, the bottom of the fixed rod is rotationally connected with the end of the drive plate away from the small electric cylinder, and the top of the fixed rod is fixedly connected with the connecting frame.

[0008] Preferably, the second drive assembly includes a geared motor fixedly mounted on the turntable, a power gear fixedly connected to the output end of the geared motor, a transmission gear meshing with the power gear, a connecting shaft fixedly connected to the transmission gear, a drive gear fixedly sleeved on the connecting shaft, a driven internal gear ring meshing with the drive gear, and a connecting column fixedly connected between the turntable and the driven internal gear ring.

[0009] Preferably, the transmission assembly includes an incomplete gear fixedly connected to the lower plate near the turntable, a short connecting plate disposed on the side of the incomplete gear, a long connecting plate rotatably connected to the short connecting plate and the short connecting plate, a transmission plate rotatably connected to the long connecting plate, a limiting plate rotatably connected to the transmission plate, and an arc-shaped plate rotatably connected to the limiting plate.

[0010] Preferably, one end of the connecting shaft is fixedly connected to the power gear, and the other end of the connecting shaft passes through the transmission gear and the turntable in sequence and is fixedly connected to one of the incomplete gears.

The other end of the arc-shaped plate is rotatably connected to the upper gathering plate via an eighth pin. The upper gathering plate is slidably installed in a guide groove opened on the outer ring surface of the lower gathering plate. The guide groove is arc-shaped.

[0011] A fully automatic wire cutting and crimping integrated equipment for automotive wire harness processing includes the following steps: The wire harness enters from the input end of the wire stripper through an external wire reel and a wire feeding mechanism. After the wire harness passes through the wire stripper, its insulation outer sheath has been removed. When the wire harness exits from the output end of the wire stripper, its end is held by a fixed electric clamp. Then, with the cooperation of a linear module, the wire straightening mechanism and the combing and twisting mechanism process the wire harness. The fixed electric clamp is released. Finally, the moving end of the electric slide table drives the moving electric clamp to feed the wire harness into the crimping area of ​​the crimping machine, where the crimping machine performs the terminal crimping operation. Preferably, after the end of the wire harness away from the copper wire bundle is clamped by the fixed electric clamp, the two drive plates move towards each other through the drive of the first drive assembly, and drive the driven plate to rotate synchronously towards each other until the drive plate and the driven plate are perpendicular. During this process, the two U-shaped frames gradually snap together, thereby wrapping the wire harness. Then, through the drive of one of the linear modules, the U-shaped frames move away from the fixed electric clamp, thereby straightening the wire harness and preventing it from bending, which would affect the subsequent crimping.

[0012] Preferably, after the wire harness is straightened, another linear module drives the limiting frame to approach the wire harness and positions the ends of the scattered copper wires at the through hole of the turntable axis. The electric push rod drives the moving electric clamp to descend and clamp the rear end of the wire harness. Driven by the second drive component, the lower gathering plate rotates upward and the upper gathering plate gradually closes upward. On the one hand, the combing column is inserted into the gaps of the scattered copper wires to initially put the copper wires back in place. On the other hand, the scattered copper wires are gathered together. At the same time, the turntable rotates to twist the copper wires back into a tight and neat state. Finally, all components are reset, and the electric slide moves the moving electric clamp, which moves the wire harness toward the crimping machine for crimping.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a wire straightening mechanism consisting of a drive plate, a driven plate, and a U-shaped frame with ball bearings, the mechanism automatically closes and clamps the insulation sheath of the wire harness after it is fixed and electrically clamped. Then, a linear module drives it to move horizontally, and the rolling of the ball bearings on the surface of the wire harness effectively straightens any bends or deformations caused by wire stripping. This process is highly automated, effectively eliminating localized bends in the wire harness, allowing it to enter the terminal in a straight state during subsequent crimping. This avoids gaps between the terminal and the insulation layer caused by crimping issues, improving the appearance quality of the crimp and the mechanical strength of the connection.

[0014] 2. A combing and twisting mechanism is constructed using a rotatable turntable and two interconnected, vertically arranged, and interlocking upper and lower gathering plates, each equipped with combing posts. When the mechanism approaches the ends of scattered copper wires, it drives the upper and lower gathering plates to close. This causes the combing posts to insert into the gaps between the copper wires for combing and repositioning, while simultaneously gathering and encircling the scattered copper wires. Simultaneously, the turntable rotates the entire combing structure slightly, and with the assistance of a movable electric clamp, the scattered and misaligned copper wires are re-twisted into a tight and neat state. This process effectively solves problems such as difficulty in inserting the wires into the terminals and poor contact caused by individual copper wires sticking out or shifting, ensuring that the copper wire bundle can be smoothly and tightly inserted into the terminals, thereby improving the reliability and safety of the electrical connection.

They are not intended to limit 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.

[0018] Please see Figures 1 to 10This invention provides a technical solution: a fully automatic wire cutting and crimping integrated equipment for automotive wire harness processing, comprising: a wire stripper 1, which is responsible for stripping the insulation of the wire harness and cutting the wire harness to a preset length; a fixed electric clamp 2 is provided on one side of the wire stripper 1, which is electrically connected to an external control device; a wire straightening mechanism, a combing and twisting mechanism, and a crimping machine 3 are sequentially arranged along the side of the fixed electric clamp 2 away from the wire stripper 1; a support rod 4 is fixedly connected to the top of the crimping machine 3 near the side of the wire stripper 1; an electric slide 5 is provided at the end of the support rod 4, which fixes the electric slide 5. The electric slide table 5 is fixedly connected to an electric push rod 43 at its moving end. The output end of the electric push rod 43 is fixedly connected to a movable electric clamp 6. The electric push rod 43, the movable electric clamp 6, and the electric slide table 5 are all electrically connected to an external control device. The bottom of the straightening mechanism and the combing and twisting mechanism are both fixedly installed on the moving end of the linear module 7. The linear module 7 drives the straightening module and the combing and twisting mechanism to move. The straightening mechanism includes a support platform 8. A pair of drive plates 9 that can rotate relative to each other are provided on the support platform 8. Each drive plate 9 is rotatably connected to a driven plate 10. One end of the driven plate 10 is slidably provided with a limit block 11, and the other end is rotatably connected with a limit block 11. A connecting frame 12 is fixedly connected to the end, and a U-shaped frame 13 is connected to the connecting frame 12. A ball bearing 14 is movably engaged on the U-shaped frame 13, with two-thirds of the ball bearing 14 engaged inside the U-shaped frame 13 and one-third exposed outside the U-shaped frame 13, allowing the ball bearing 14 to rotate flexibly. A first drive assembly is provided below the support platform 8 to drive the two drive plates 9 to rotate in opposite directions, so that the U-shaped frame 13 can perform clamping or releasing actions on the wire harness. The combing and twisting mechanism includes a limiting frame 15, and a turntable 16 is rotatably mounted on the top of the limiting frame 15. An annular groove is formed on the outer surface of the turntable 16, which connects to the limiting frame 15. The locking mechanism ensures the stability of the turntable 16 rotation. A pair of lower gathering plates 17 that can rotate relative to each other are provided on the turntable 16. The lower gathering plates 17 are connected to the upper gathering plate 18 through a transmission assembly. The inner rings of both the lower gathering plates 17 and the upper gathering plate 18 are fixedly provided with combing columns 19. The combing columns 19 on the lower gathering plates 17 and the upper gathering plate 18 are arranged in a front-to-back manner. A second drive assembly is provided on the other side of the turntable 16 to drive the turntable 16 to rotate and simultaneously drive the two lower gathering plates 17 to rotate in opposite directions or in opposite directions. Then, through the transmission assembly, the upper gathering plate 18 is driven to close upward or unfold downward to achieve the twisting or release of the copper wire bundle.

[0019] The wire harness enters from the input end of the wire stripper 1 through an external wire reel and a wire feeding mechanism. After passing through the wire stripper 1, the insulation outer sheath of the wire harness at the front end has been stripped. When the wire harness comes out from the output end of the wire stripper 1, its end is first clamped by the fixed electric clamp 2. At this time, driven by the first drive assembly, the two drive plates 9 on the support platform 8 rotate towards each other around a fixed point at one end, thereby driving the driven plate 10 connected to it to move. The driven plate 10 slides under the limit of the limit block 11 and moves closer to the center of the support platform 8 until the drive plate... When the driven plate 10 and the two driven plates 10 are perpendicular, the U-shaped frames 13 on the connecting frame 12 are engaged, limiting the wire harness within the two U-shaped frames 13 and bringing the insulation sheath of the wire harness into contact with the ball bearings 14. Then, the linear module 7 located below the support platform 8 moves the support platform 8 away from the wire stripper 1, and the U-shaped frames 13 move synchronously. The ball bearings 14 slide on the outer surface of the wire harness, straightening the wire harness to facilitate subsequent precise crimping. Then, the linear module 7 at the bottom of the limiting frame 15 moves the turntable 1... The wire stripper 6 moves closer to the wire stripper 1, positioning the ends of the scattered copper wires at the through-hole of the turntable 16. The electric push rod 43 drives the moving electric clamp 6 to descend and clamp the wire harness, thus preventing the wire harness from rotating during subsequent twisting. Then, driven by the second drive assembly, the lower gathering plate 17 rotates upwards, and the upper gathering plate 18 gradually closes upwards through the transmission assembly, forming an encircling state between the lower gathering plate 17 and the upper gathering plate 18. On one hand, the combing column 19 inserts into the gaps between the scattered copper wires, initially repositioning the copper wires; on the other hand, it... The scattered copper wires are gathered together, and at the same time, the turntable 16 rotates to twist the copper wires back into a tight and neat state. Finally, the wire straightening mechanism and the combing and twisting mechanism are reset. The electric slide table 5 drives the moving electric clamp 6 to move through the connection of the electric push rod 43. At the same time, the fixed electric clamp 2 is released, so that the moving electric clamp 6 moves the wire harness to the crimping point of the crimping machine 3. The crimping machine 3 crimps the terminals on the material strip, and the operator can then remove it. If the wire harness does not need to be processed after stripping, it can be directly crimped by the cooperation of the electric slide table 5 and the moving electric clamp 6.

[0020] The lower surface of the support platform 8 is fixedly connected to the moving end of one of the straight modules 7. The limiting block 11 is rotatably connected to the support platform 8 through the limiting shaft 20, so that the limiting block 11 can rotate. The first drive assembly includes a small electric cylinder 21, which is electrically connected to an external control device; a support base 22 rotatably connected to the non-output end of the small electric cylinder 21, which provides limiting support for the small electric cylinder 21; a connecting rod 23 rotatably connected to the output end of the small electric cylinder 21; a drive shaft 24 fixedly connected to the connecting rod 23; a drive gear 25 fixedly connected to the drive shaft 24; and a driven gear 26 meshing with the drive gear 25. The drive gear 25 and the driven gear 26 mesh and transmit power. The output end of the electric cylinder 21 is rotatably connected to one end of the connecting rod 23 via a limiting pin. The other end of the connecting rod 23 is fixedly connected to the bottom end of the drive shaft 24. The top end of the drive shaft 24 passes through the support platform 8 and is fixedly connected to the drive gear 25 and one end of one of the drive plates 9 in sequence. The other drive plate 9 is fixedly connected to the driven gear 26 via a driven shaft 27. The bottom end of the driven shaft 27 is rotatably sleeved in the support platform 8. The support platform 8 supports and limits the drive shaft 24 and the driven shaft 27. A fixed rod 28 is fixedly connected to the end of the driven plate 10 away from the limiting block 11. The bottom of the fixed rod 28 is rotatably connected to the end of the drive plate 9 away from the small electric cylinder 21. The top of the fixed rod 28 is fixedly connected to the connecting frame 12.

[0021] When the end of the wire harness away from the copper wire bundle is clamped by the fixed electric clamp 2, the output end of the small electric cylinder 21 extends, pushing the connecting rod 23 to move through the connection of the limit pin. The other end of the small electric cylinder 21 is limited and supported by the support seat 22. Under the limit connection of the drive shaft 24, the connecting rod 23 pushes the bottom of the drive shaft 24 to rotate. The drive shaft 24 then drives the drive gear 25 and one of the drive plates 9, which are fixedly connected to its top, to rotate synchronously. While the drive gear 25 rotates, it meshes with the driven gear 26. The driven gear 26, under the connection of the driven shaft 27, drives the other drive plate 9 to rotate synchronously. This causes the two drive plates 9 to rotate towards each other with the drive shaft 24 and the driven shaft 27 as their axes, respectively. At the same time, under the rotational connection of the fixed rod 28, the driven plate 10 is driven to move, pulling the two driven plates 10 to move towards each other. The driven plates 10 are moved towards each other by the limit block 11. The limit block 11 is limited by the limit shaft 20, which causes the ends of the two driven plates 10 with the connecting frame 12 to gradually approach each other until the drive plate 9 and the driven plate 10 are perpendicular. At this time, the two U-shaped frames 13 are in contact, binding the wire harness inside. The linear module 7 installed at the bottom of the support platform 8 drives the support platform 8 to move away from the wire stripper 1, which also indirectly drives the U-shaped frame 13 to move synchronously. The U-shaped frame 13 makes a horizontal linear movement, and the sliding of the ball bearing 14 between the wire harnesses straightens the wire harness. This avoids the existence of tiny gaps between the terminal and the wire harness insulation layer, which not only affects the appearance but may also weaken the mechanical strength of the connection, posing a hidden danger to the long-term stable use of the wire harness. At the same time, it also improves the accuracy of terminal crimping. Finally, the linear module 7 and the small electric cylinder 21 are controlled to move in opposite directions to reset the above components, which is convenient for subsequent processing.

[0022] The second drive assembly includes a geared motor 29 fixedly mounted on the turntable 16, the geared motor 29 being electrically connected to an external control device, a power gear 30 fixedly connected to the output end of the geared motor 29, a transmission gear 31 meshing with the power gear 30, the transmission gear 31 being disposed on the upper side of the power gear 30, a connecting shaft 32 fixedly connected to the transmission gear 31, a drive gear 33 fixedly sleeved on the connecting shaft 32, a driven internal gear ring 34 meshing with the drive gear 33, the drive gear 33 and the driven internal gear ring 34 being internally meshed, and a connecting post 35 fixedly connected between the turntable 16 and the driven internal gear ring 34.

[0023] The transmission assembly includes an incomplete gear 36 fixedly connected to the side of the lower converging plate 17 near the turntable 16, a short connecting plate 37 disposed on one side of the incomplete gear 36, a long connecting plate 38 rotatably connected to the short connecting plate 37 and the short connecting plate 37, a transmission plate 39 rotatably connected to the long connecting plate 38, a limiting plate 41 rotatably connected to the transmission plate 39, and an arc-shaped plate 40 rotatably connected to the limiting plate 41. One end of the connecting shaft 32 is fixedly connected to the power gear 30, and the other end of the connecting shaft 32 passes through the transmission gear 31 and the turntable 16 in sequence and is fixedly connected to one of the incomplete gears 36. The turntable 16 is rotatably connected to the connecting shaft 32, and the other incomplete gear 36 is rotatably connected to the turntable 16 through a support shaft 42. One end of the short connecting plate 37 is connected to the lower converging plate 17. The short connecting plate 37 is rotatably connected to the long connecting plate 38 via the first pin. The other end of the short connecting plate 37 is rotatably connected to one side of the long connecting plate 38 via the second pin. One end of the long connecting plate 38 is rotatably connected to the turntable 16 via the third pin. The other end of the long connecting plate 38 is rotatably connected to one end of the transmission plate 39 via the fourth pin. The other end of the transmission plate 39 is rotatably connected to one side of the limiting plate 41 via the fifth pin. One end of the limiting plate 41 is rotatably connected to the turntable 16 via the sixth pin. The other end of the limiting plate 41 is rotatably connected to one end of the arc plate 40 via the seventh pin. The other end of the arc plate 40 is rotatably connected to the upper gathering plate 18 via the eighth pin. The upper gathering plate 18 is slidably installed in the guide groove opened on the outer ring surface of the lower gathering plate 17. The guide groove is arc-shaped and guides and limits the upper gathering plate 18 through the lower gathering plate 17.

[0024] After the wire harness is straightened and the straightening mechanism resets, the electric push rod 43 drives the movable electric clamp 6 downward to clamp the rear of the wire harness. Another linear module 7 drives the limit frame 15 to move closer to the wire harness, causing the turntable 16 to move synchronously and positioning the ends of the spread copper wires at the through-hole of the turntable 16's axis. The electric push rod 43 then drives the movable electric clamp 6 downward to clamp the rear end of the wire harness. At this point, the fixed electric clamp 2 releases. By controlling the reduction motor 29, it drives the power gear 30 to rotate. The power gear 30 meshes with the transmission gear 31, which is connected to the connecting shaft 32. The driving gear 33 and one of the incomplete gears 36 rotate synchronously. The driving gear 33 meshes with the driven internal gear ring 34, thereby driving the driven internal gear ring 34 to rotate. Under the connection of the connecting column 35, the driven internal gear ring 34 drives the turntable 16 to rotate under the limit of the limit frame 15. At the same time, when one of the incomplete gears 36 rotates, it meshes with the other incomplete gear 36, causing the lower closing plate 17, which is fixedly connected to the incomplete gear 36, to rotate upward and tend to tighten. The rotational connection of the short connecting plate 37 drives the long connecting plate 38 to move upward, making... The long connecting plate 38 rotates around its limiting point with the turntable 16, thereby pulling the transmission plate 39 upward. The transmission plate 39, through its rotational connection with the limiting plate 41, also pulls the limiting plate 41 to rotate around its limiting point with the turntable 16. Then, through the rotational connection of the arc plate 40 with the limiting plate 41 and the upper gathering plate 18, the upper gathering plate 18 moves upward and slides under the guide groove opened on the outer ring surface of the lower gathering plate 17. This causes the upper gathering plate 18 to move upward towards each other while also having a tendency to embrace. In this way, on the one hand, the combing column 19 is inserted into the gaps of the scattered copper wires, and the copper wires are initially combed. The first step involves returning the wire harness to its original position. On the other hand, the scattered copper wires are gathered together. At the same time, the turntable 16 rotates slightly at a certain angle. At this time, the wire harness is clamped and limited by the movable electric clamp 6. With the cooperation of the combing column 19, the copper wires are twisted back into a tight and neat state, completing the twisting and combing of the wire harness. Then, the reduction motor 29 and the linear module 7 are reset. Next, the electric slide table 5 drives the movable electric clamp 6 to move through the connection of the electric push rod 43, so that the movable electric clamp 6 moves the wire harness towards the crimping machine 3 and aligns the end of the wire harness with the terminal for insertion. Finally, the crimping machine 3 performs the crimping, and then the operator can remove it.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
