Description

Technical Field

[0001] This invention relates to the field of terminal crimping technology, and more particularly to a wire harness terminal crimping device. Background Technology

[0002] Wire harness terminal crimping is a critical process in wire harness manufacturing, and its quality directly affects the reliability and safety of electrical connections. Currently, in large-scale, continuous wire harness production, common technical solutions and equipment still suffer from the following problems:

[0003] 1. Most existing equipment can only complete a single process independently, such as separate cutting, peeling or crimping equipment. The processes rely on manual handling or simple mechanical transfer, which leads to interruptions in the processing flow and longer cycle times. It is impossible to form an integrated production line from continuous wire harness to the completion of crimping at both ends, which restricts the further improvement of overall production efficiency.

[0004] 2. Since the equipment for each process is independent, the wire harness needs to be repositioned and clamped multiple times in the cutting, stripping and crimping stages, which is cumbersome. Moreover, each positioning may produce deviations, which can easily lead to inconsistent stripping lengths and inaccurate crimping positions, affecting the dimensional accuracy and electrical performance consistency of the final product.

[0005] 3. The combined use of multiple independent devices usually requires more space for operation and turnover, resulting in a less compact layout. This is not conducive to the intensive planning and management of the workshop production line, and also increases the material flow distance and time.

[0006] Therefore, it is necessary to develop a wire harness terminal crimping device that can improve the level of mechanization, adapt to multiple specifications of wire harnesses, and has high crimping accuracy and good stability, so as to improve production efficiency, ensure product quality and reduce dependence on operators.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] See Figures 1-8 This invention provides a wire harness terminal crimping device, including a base 1, a feeding mechanism 2, a cutting and stripping mechanism 3, a crimping mechanism 4, and a feeding mechanism 5. The base 1 is a box structure, which is set on the ground or other supporting surface. The cutting and stripping mechanism 3 is provided on the top surface of the base 1. The cutting and stripping mechanism 3 includes a cutting blade 321 for cutting continuous wire harnesses and a stripping blade 351 for stripping the insulation from the ends of the wire harnesses. Cutting involves dividing the continuous wire harness into independent wire harnesses of basically the same length. Stripping involves removing part of the insulation from the ends of the wire harnesses. The terminal is crimped onto the cut insulation at the ends of the wire harnesses.

[0036] The feeding and discharging sides of the cutting and stripping mechanism 3 are respectively equipped with a feeding mechanism 2 and a discharging mechanism 5. A crimping mechanism 4 is provided next to both the feeding and discharging mechanisms 2 and 5. The feeding mechanism 2 includes a horizontally swingable rotating seat 213. A guide wheel 25 is rotatably mounted on the rotating seat 213. The guide wheel 25 is used to transport the continuous wire harness to the cutting blade 321 for cutting. Specifically, there are two guide wheels 25, which are positioned between the two guide wheels 25 during wire harness transport. The rotating seat 213 is used to sequentially transport the cut end of the wire harness (i.e., the cut end of the continuous wire harness) to the stripping blade 351 and the crimping mechanism 4. After completing the stripping and crimping of the wire harness end, the rotating seat 213 drives the wire harness to swing back to its original position and continues to transport the wire harness.

[0037] The feeding mechanism 5 includes a horizontally swingable guide rail, on which a gripper 562 is slidably mounted. The gripper 562 is used to grip the wire harness passing through the cutting and stripping mechanism 3. When the gripper 562 grips the wire harness, the cutting and stripping mechanism 3 cuts the wire harness. At this time, the gripper 562 is gripping an independent wire harness, and the end of the wire harness away from the cutting and stripping mechanism 3 has completed the stripping and terminal crimping operations. The guide rail is used to sequentially transport the tail end of the wire harness (i.e. the end of the independent wire harness that has not been crimped with a terminal) to the stripping knife 351 and the crimping mechanism 4 to complete the stripping and terminal crimping of the tail end of the wire harness.

[0038] See Figures 1-4 The feeding mechanism 2 is located on one side of the cutting and peeling mechanism 3, which is the feeding side of the cutting and peeling mechanism 3. The feeding mechanism 2 includes a feeding frame plate and a fixed shaft 21. The feeding frame plate is fixedly connected to the top surface of the base 1. The feeding frame plate is provided with a vertical fixed shaft 21, and the two ends of the fixed shaft 21 are fixedly connected to the feeding frame plate and the base 1, respectively. A rotating seat 213 is provided at the feeding frame plate. The fixed shaft 21 passes through the rotating seat 213. A support plate 214 is provided below the rotating seat 213. The support plate 214 abuts against the top surface of the base 1, and multiple support springs are fixedly connected between the support plate 214 and the rotating seat 213. Specifically, the support springs are all compression springs. When the support springs are in their natural state, there is a certain gap between the support plate 214 and the rotating seat 213. A sliding bushing 211 is rotatably connected to the rotating seat 213. The sliding bushing 211 is slidably sleeved on the fixed shaft 21. A guide groove 212 is provided on the surface of the sliding bushing 211. The guide groove 212 includes a first vertical section, a first inclined section, a second vertical section, a second inclined section and a third vertical section that are connected sequentially from top to bottom.

[0039] See Figures 1-4A drive screw 27 is provided on the side of the sliding bushing 211 near the center of the base 1. The drive screw 27 is rotatably connected to the rotating seat 213. A lifting seat 271 is threadedly connected to the drive screw 27. The sliding bushing 211 passes through the lifting seat 271. A guide post that cooperates with the guide groove 212 is fixedly connected to the lifting seat 271. When the drive screw 27 rotates, it can drive the lifting seat 271 to rise or fall along the drive screw 27. During the descent of the lifting seat 271, when the guide post is inside the first vertical section, the rotating seat 213 is facing the stripping mechanism 3. At this time, the stripping mechanism 3 can cut the continuous wire harness. When the guide post passes through the first inclined section and enters the second vertical section, the rotating seat 213 swings horizontally around the axis of the fixed shaft 21 at a certain angle. At this time, the stripping mechanism 3 can strip the first end of the continuous wire harness. When the guide post passes through the second inclined section and enters the third vertical section, the rotating seat 213 continues to swing horizontally in the original direction. At this time, the crimping mechanism 4 can crimp the first end of the continuous wire harness.

[0040] See Figures 1-4 A wire feeder 22 is horizontally slidably connected to the top of the rotating base 213 near the center of the base 1. Multiple insert plates 215, which penetrate the interior of the wire feeder 22, are fixedly connected to the rotating base 213. Multiple return springs are fixedly connected between the wire feeder 22 and the rotating base 213. Two meshing wire feeder gears 23 are rotatably connected to the wire feeder 22. A wire feeder drive (not shown in the figure) is fixedly mounted on the wire feeder 22. The output shaft of the wire feeder drive is connected to one of the wire feeder gears 23 via a coupling, enabling it to drive the two wire feeder gears 23 to rotate synchronously in opposite directions. An adjusting seat 24 is slidably connected to the wire feeder 22. A receiving box 241 is fixedly connected to the top surface of the adjusting seat 24. A horizontally arranged adjusting screw 252 is rotatably connected inside the receiving box 241. The adjusting screw 252 is a screw structure with reverse threads at both ends. Two adjusting blocks are threadedly connected to the adjusting screw 252. The top surface of each adjusting block is rotatably connected to an auxiliary gear 251 that can mesh with the wire feeder 23. There is no meshing relationship between the two auxiliary gears 251. A guide wheel 25 is fixedly connected to the top surface of the auxiliary gear 251.

[0041] By turning the adjusting screw 252, the distance between the two guide wheels 25 can be adjusted, thus enabling the feeding mechanism 2 to be suitable for conveying wire harnesses of various diameters. Specifically, a scale value can be set on the top surface of the receiving box 241 to visually display the distance between the two guide wheels 25 and facilitate checking whether the positions of the two adjusting blocks are symmetrical. When the auxiliary gear 251 meshes with the wire feeding gear 23 in a one-to-one correspondence, the wire feeding drive is activated, driving the two guide wheels 25 to rotate synchronously in opposite directions, thus conveying the wire harness located between the two guide wheels 25.

[0042] Furthermore, a wire feeder 22 is fixedly connected to a wire seat at the end away from the rotating seat 213. The wire seat has a wire hole that runs horizontally through it. The continuous wire bundle passes through the wire hole, and the wire seat and the wire hole can guide the continuous wire bundle.

[0043] See Figures 1-4 A tensioning plate 242 is slidably connected to the bottom surface of the wire feeder 22. Multiple tensioning springs are fixedly connected between the tensioning plate 242 and the adjusting seat 24. An elastic locking plate 244 is provided on the top surface of the end of the tensioning plate 242 away from the center of the base 1. The elastic locking plate 244 includes a locking plate and a spring assembly. The locking plate is vertically slidably connected to the tensioning plate 242, and the spring assembly is fixedly connected to the locking plate and the tensioning plate 242. A locking groove corresponding to the locking plate is opened on the bottom surface of the wire feeder 22. A vertical through slot 243 is provided on the tension plate 242 located on the side of the elastic locking plate 244 away from the center of the base 1. An unlocking plate 26 is horizontally slidable on the top of the rotating seat 213. A protrusion 261 that passes through the through slot 243 is fixedly connected to the bottom surface of the unlocking plate 26 near the tension plate 242. The length of the through slot 243 is greater than the diameter of the protrusion 261. Multiple pre-tension springs are fixedly connected between the unlocking plate 26 and the rotating seat 213. The elastic coefficient of the pre-tension springs is greater than that of the tension springs. When the pre-tension springs are in their natural state, the locking plate engages with the locking slot, the tension springs are in a compressed state, and the auxiliary gear 251 meshes with the wire feeding gear 23 in a corresponding manner. A bent push plate 272 that can engage with the unlocking plate 26 is fixedly connected to the top surface of the lifting seat 271. When the lifting seat 271 rises to the top of the drive screw 27, the bent push plate 272 can push the unlocking plate 26 to move horizontally towards the center of the base 1.

[0044] When the locking plate engages with the locking groove and the unlocking plate 26 initially moves horizontally towards the tensioning plate 242, the tensioning plate 242 does not move initially because the length of the through groove 243 is greater than the diameter of the protrusion 261. The protrusion 261 moves within the through groove 243 until the unlocking plate 26 abuts against the locking plate. Both the unlocking plate 26 and the locking plate have chamfers that engage with each other. The unlocking plate 26 can push the locking plate back into the tensioning plate 242, thereby disengaging the locking plate from the locking groove. The tensioning plate 242 can then move towards the center of the base 1, disengaging the auxiliary gear 251 from the wire feeding gear 23. At this time, the distance between the two guide wheels 25 can be adjusted.

[0045] See Figures 1-4A vertical auxiliary plate 28 is provided on the side of the drive screw 27 away from the sliding bushing 211. The bottom of the auxiliary plate 28 is slidably connected to the connecting seat 282. The connecting seat 282 is fixedly connected to the rotating seat 213. An auxiliary spring (not shown in the figure) is fixedly connected inside the connecting seat 282 to abut against the auxiliary plate 28. The top of the auxiliary plate 28 passes through the lifting seat 271. The lifting seat 271 has a clearance groove corresponding to the auxiliary plate 28. Two wedge blocks 281 are fixedly connected to the side wall of the auxiliary plate 28. The heights of the two wedge blocks 281 correspond to the second and third vertical sections of the guide groove 212, respectively. A roller 273 is horizontally slidably arranged in the clearance groove. A compression spring is fixedly connected to the side wall of the clearance groove. The compression spring applies a force to the roller 273 in the direction of the wedge block 281. Specifically, the compression springs are all compression springs. A push block 283 is fixedly connected to the top of the auxiliary plate 28. The top of the push block 283 abuts against the rotating seat 213. The push block 283 and the wire feed seat 22 are provided with mutually cooperating ramps.

[0046] When the lifting seat 271 descends to the wedge block 281, under the combined action of the wedge block 281, roller 273, and compression spring, the compression spring does not deform or deforms slightly. The auxiliary plate 28 and the push block 283 descend synchronously for a certain distance, compressing the auxiliary spring. Under the action of the push block 283 and the ramp of the wire feeder 22, the wire feeder 22 can be pushed to move a certain distance away from the fixed shaft 21, and the return spring is stretched. When the auxiliary plate 28 reaches the bottom of its range of motion, the lifting seat 271 continues to descend, but the auxiliary plate 28 can no longer descend. Therefore, the compression spring deforms, causing the lifting seat 271 to pass through the wedge block 281. Under the action of the auxiliary spring and the return spring, both the auxiliary plate 28 and the wire feeder 22 can automatically return to their original positions. When the lifting seat 271 rises to the wedge block 281, the auxiliary plate 28 cannot move upward because the top surface of the push block 283 abuts against the rotating seat 213. The compression spring deforms, allowing the lifting seat 271 to rise smoothly. During this process, there is no relative movement between the wire feeder 22 and the rotating seat 213.

[0047] See Figures 1-4 A vertical drive shaft 29 is rotatably connected to the rotating seat 213. The drive shaft 29 is connected to the drive screw 27 through a belt drive mechanism or a synchronous belt drive mechanism, so that the drive shaft 29 can drive the drive screw 27 to rotate. An adjustment drive component 291 is fixedly installed on the rotating seat 213. The output shaft of the adjustment drive component 291 is connected to the drive shaft 29 through a coupling.

[0048] See Figure 1 and Figure 5The stripping mechanism 3 includes a fixed frame 31 and stripping screws 311. The fixed frame 31 is fixedly connected to the top surface of the base 1. Vertical stripping screws 311 are rotatably connected to both ends of the fixed frame 31. The two stripping screws 311 are connected by a synchronous belt drive mechanism. Specifically, synchronous pulleys are installed on the stripping screws 311, and the two synchronous pulleys are connected by a synchronous belt to make the two stripping screws 311 rotate synchronously. This is a mature existing technology and will not be described in detail. A stripping drive component 312 is fixedly installed on the fixed frame 31. The output shaft of the stripping drive component 312 is connected to one of the stripping screws 311 through a coupling. Two opposing cutting blade seats 32 are passed through the stripping screws 311. The cutting blade seats 32 are slidably connected to the fixed frame 31 in the vertical direction. Cutting blades 321 are fixedly connected to the opposing surfaces of the cutting blade seats 32. The two cutting blades 321 are used to cut the wire harness.

[0049] See Figure 1 and Figure 5 Each of the cutting blade holders 32 has a peeling blade holder 34 on one of its opposite sides. Multiple buffer springs, specifically compression springs, are fixedly connected between adjacent cutting blade holders 32 and peeling blade holders 34. The surface of the cutting screw 311 has symmetrically arranged threads in opposite directions. The two threads on the same cutting screw 311 respectively mate with two peeling blade holders 34, meaning the peeling blade holders 34 are threadedly connected to the cutting screw 311. When the cutting screw 311 rotates, the two peeling blade holders 34 move synchronously in opposite directions. Each end of the peeling blade holder 34 has an outwardly extending extension plate. The two extension plates on the same peeling blade holder 34 are arranged diagonally and alternately. A support seat 35 is fixedly connected to the opposite surface of each extension plate, and a peeling blade 351 is fixedly connected to the opposite surface of each support seat 35.

[0050] The feeding mechanism 2 conveys a continuous wire harness. When the continuous wire harness reaches the cutting and stripping mechanism 3, the cutting and stripping drive 312 drives the cutting and stripping screw 311 to rotate, causing the two stripping blade seats 34 to move closer to the cutting blade seat 32. The cutting blade 321 cuts the wire harness. After the cutting operation is completed, the cutting and stripping drive 312 reverses, causing the stripping blade seat 34 and the cutting blade seat 32 to return to their original positions. The lifting seat 271 descends until the guide column passes through the first inclined section and enters the second vertical section, causing the rotating seat 213 to rotate around the axis of the fixed shaft 21 by a certain angle, so that the beginning of the continuous wire harness corresponds to one of the sets of stripping blades 351. The guide column continues to move downward along the second vertical section, the rotating seat 213 does not swing, and the roller 273 cooperates with the wedge block 281 located above, causing the wire feeder 22 to move a certain distance away from the rotating seat 213, sending the beginning of the continuous wire harness between the stripping blades 351 for cutting and stripping. The drive unit 312 restarts, causing the stripping blade 351 to strip the wire harness end. After cutting the wire, the stripping blade 351 does not immediately return to its initial position, but instead retracts a small distance under control, maintaining contact with the cut wire while keeping a distance from the wire harness core. Then, the roller 273 disengages from the wedge block 281 above, causing the wire feeder 22 to move and reset. Under the limiting action of the stripping blade 351, the cut wire automatically falls off the continuous wire harness. The lifting seat 271 moves until the guide column passes through the second inclined section and enters the third vertical section. The rotating seat 213 continues to swing at a certain angle in the original direction, aligning the end of the continuous wire harness with the crimping mechanism 4 next to the feeding mechanism 2.

[0051] See Figure 1 , Figure 6 and Figure 7 The pressing mechanism 4 includes a pressing box 41 and a bottom mold 411. The pressing box 41 is fixedly connected to the top surface of the base 1. The bottom mold 411 is detachably connected to the pressing box 41. A pressing drive is provided inside the pressing box 41. A pressing block 421 is fixedly connected to the lower pressing shaft 42 of the pressing drive. A top mold 422 corresponding to the bottom mold 411 is detachably connected to the bottom surface of the pressing block 421.

[0052] In the prior art, terminals are usually manufactured by precision stamping process. In order to adapt to mechanized production and improve efficiency, terminals are generally stamped in an array on a continuous carrier tape. The crimping box 41 is provided with guide holes corresponding to the carrier tape. When crimping the terminal, the terminal is located above the bottom mold 411. The stripped wire harness end is inserted into the conductor crimping cylinder of the terminal. The top mold 422 is located above the wire harness and the terminal. At this time, the crimping block 421 descends and applies a squeezing force. Under the action of the top mold 422 and the bottom mold 411, the terminal deforms and covers the stripped wire harness.

[0053] Both the top mold 422 and the bottom mold 411 are equipped with separation tools. When crimping the terminals, the separation tools cut off the connecting bridge of the carrier tape (i.e., the connection between the carrier tape and the terminal), so that the terminal is separated from the carrier tape. This is a mature existing technology, so it will not be described in detail.

[0054] See Figure 1 , Figure 6 and Figure 7 A bracket 43 is fixedly connected to the pressing box 41 on one side of the pressing block 421. A swing arm 44 is connected to the bracket 43, and the top of the swing arm 44 is hinged to the bracket 43. A torsion spring is connected to the hinge point between the swing arm 44 and the bracket 43. When the torsion spring is in its natural state, the swing arm 44 is in a vertical state. An inclined guide bar 441 is fixedly connected to the swing arm 44, and a lever 425 corresponding to the inclined guide bar 441 is fixedly connected to the pressing block 421. When the pressing block 421 descends, under the action of the lever 425 and the inclined guide bar 441, the swing arm 44 can be driven to swing around the hinge point between itself and the bracket 43 at a certain angle. A translation plate 442 is slidably connected to the pressing box 41 below the swing arm 44. A horizontal transmission column is fixedly connected to the translation plate 442. The bottom end of the swing arm 44 has a waist-shaped groove corresponding to the transmission column. When the swing arm 44 swings, it can drive the translation plate 442 to slide horizontally.

[0055] See Figure 1 , Figure 6 and Figure 7 The crimping box 41 has a receiving groove with a connecting guide hole at the top of the guide hole. A conveyor roller 46 is rotatably connected to the crimping box 41 at the receiving groove. The conveyor roller 46 abuts against the carrier belt. When the conveyor roller 46 rotates, it can drive the carrier belt to move a certain distance, realizing automatic terminal feeding. A conveyor gear 461 is rotatably connected to the conveyor roller 46. A ratchet 462 is fixedly connected to the side wall of the conveyor gear 461. The ratchet 462, the conveyor gear 461 and the conveyor roller 46 are coaxially arranged. A pawl that can rotate in one direction is hinged to the conveyor roller 46. A conveyor seat 47 is horizontally slidably connected to the crimping box 41 between the conveyor roller 46 and the translation plate 442. A rack 471 that can mesh with the conveyor gear 461 is fixedly connected to the conveyor seat 47. A vertical ear plate 472 is fixedly connected to one end of the conveyor seat 47 near the translation plate 442. A horizontal auxiliary screw 45 is fixedly connected to the translation plate 442. The auxiliary screw 45 passes through the ear plate 472. An auxiliary block 451 is threadedly connected to the auxiliary screw 45 on both sides of the ear plate 472.

[0056] By adjusting the distance between the auxiliary block 451 and the ear plate 472, the translation range of the conveyor seat 47 can be changed, thereby changing the rotation angle of the conveyor roller 46 to meet the feeding requirements of various terminals. When the crimping block 421 moves downward, under the action of the inclined guide bar 441 and the lever 425, the swing arm 44 is forced to swing at a certain angle. When the swing arm 44 swings, it can push the translation plate 442 to move horizontally. The translation plate 442 abuts against and pushes the conveyor seat 47 to move horizontally through the auxiliary block 451. Under the meshing action of the conveyor gear 461 and the rack 471, the conveyor roller 46 is driven to rotate at a certain angle to realize the automatic feeding of terminals.

[0057] After the terminal crimping at the beginning of the wire harness is completed, the rotating seat 213 swings back to its original position, the wire feeding drive is started, and the wire harness is transported to the end of the cutting and stripping mechanism 3 away from the feeding mechanism 2. At this time, the unloading mechanism 5 clamps the wire harness, the cutting and stripping mechanism 3 cuts the wire harness, and the unloading mechanism 5 drives the wire harness to swing. Referring to the above processing process, the stripping and terminal crimping operations at the end of the wire harness are completed in sequence.

[0058] See Figure 1 and Figure 8 The feeding mechanism 5 includes a feeding rack plate 51 and a rotating shaft 52. The feeding rack plate 51 is located on the side of the cutting and peeling mechanism 3 away from the feeding mechanism 2 (i.e., the discharge side). The feeding rack plate 51 is fixedly connected to the top surface of the base 1. The rotating shaft 52 is rotatably connected to the feeding rack plate 51, and an upper gear 521 is fixedly connected to the rotating shaft 52. A horizontal guide rail is fixedly connected to the bottom end of the rotating shaft 52. A drive shaft 54 ​​is rotatably connected to the feeding rack plate 51 on the side of the rotating shaft 52 away from the cutting and peeling mechanism 3. A feeding drive component 543 is fixedly installed on the top surface of the feeding rack plate 51. The output shaft of the feeding drive component 543 is connected to the drive shaft 54 ​​through a coupling. The feeding drive component 543 can drive the drive shaft 54 ​​to rotate forward or backward. A drive gear 541 is fixedly connected to the drive shaft 54. The drive gear 541 is an incomplete gear with three tooth areas on its circumferential surface. When the tooth areas on the drive gear 541 mesh with the upper gear 521, it can drive the rotating shaft 52 to rotate, thereby realizing the horizontal swing of the guide rail. The three tooth areas mesh with the upper gear 521 in sequence. During the swing of the guide rail, the stripping, terminal crimping and release of the wire harness tail end are completed.

[0059] See Figure 1 and Figure 8A translation guide seat 55 is slidably mounted on the guide rail, allowing it to slide horizontally along the guide rail. A clamping cylinder 561 is located at the end of the translation guide seat 55 furthest from the rotating shaft 52. The clamping cylinder 561 is fixedly mounted on the elastic support seat 56 and connected to the clamping seat. A clamping jaw 562 for clamping the wire harness is hinged to the clamping seat. The clamping cylinder 561 provides power to the clamping jaw 562, enabling the clamping and release of the wire harness. Multiple guide shafts passing through the translation guide seat 55 are fixedly connected to the elastic support seat 56. Each guide shaft is fitted with a cooperating spring; specifically, all cooperating springs are compression springs.

[0060] See Figure 1 and Figure 8 A rotating sleeve 53 is rotatably mounted on the rotating shaft 52 below the upper gear 521. A lower gear 522 is fixedly connected to the top of the rotating sleeve 53. A driven seat 531 passes through the rotating sleeve 53. The driven seat 531 has a through hole for the rotating sleeve 53 to pass through. A circulation groove is formed on the surface of the rotating sleeve 53. A guide corresponding to the circulation groove is fixedly connected to the inner wall of the through hole. The circulation groove is an arc-shaped groove that circles the surface of the rotating sleeve 53 and is connected end to end. Its structure can be referred to as the groove structure of the surface of a cylindrical grooved cam. The driven seat 531 reciprocates once for each rotation of the rotating sleeve 53. A connecting rod 532 is provided between the driven seat 531 and the translation guide 55. One end of the connecting rod 532 is hinged to the driven seat 531, and the other end of the connecting rod 532 is hinged to the translation guide 55. A turntable 542 is fixedly connected to the drive shaft 54. The turntable 542 has two toothed areas. The toothed areas on the drive gear 541 and the toothed areas on the turntable 542 are staggered. That is, when the toothed areas on the drive gear 541 mesh with the upper gear 521, the toothed areas on the turntable 542 do not mesh with the lower gear 522; when the toothed areas on the turntable 542 mesh with the lower gear 522, the toothed areas on the drive gear 541 do not mesh with the upper gear 521.

[0061] See Figure 1 Preferably, this device can also be used with automatic feeding equipment, such as wire harness feeding mechanism and terminal feeding mechanism. Taking the wire harness feeding mechanism as an example, a wire harness feeding frame body can be set up and fixedly connected to the feeding frame plate. A wire harness winding roller is rotatably set on the wire harness feeding frame body. The wire harness is continuously wound on the wire harness winding roller. A feeding drive component is set on the wire harness feeding frame body to drive the wire harness winding roller to rotate, so as to realize automatic and continuous feeding of the wire harness. The wire harness feeding mechanism and the terminal feeding mechanism are both mature existing technologies, so they will not be described in detail.

[0062] See Figure 6 and Figure 7Preferably, a mounting bracket 423 is fixedly connected to the lower pressing shaft 42, and a downward-pointing pressing rod 424 is fixedly connected to the mounting bracket 423. When the pressing rod 424 descends synchronously with the lower pressing shaft 42, it can press down on the rotating seat 213 or the elastic bearing seat 56, so that the wire harness remains horizontal or nearly horizontal when the terminal is crimped, avoiding bending that could lead to poor terminal connection.

[0063] See Figure 6 and Figure 7 Preferably, a positioning plate 48 is vertically slidably connected to the top surface of the guide hole. The positioning plate 48 is elastically connected to the pressing box 41, that is, a positioning spring is fixedly connected between the positioning plate 48 and the pressing box 41. Specifically, the positioning spring is a compression spring. When the swing arm 44 is in a vertical state, the conveyor seat 47 is located above the positioning plate 48, pressing the positioning plate 48 into the guide hole. The bottom surface of the positioning plate 48 is provided with a positioning post, which cooperates with the positioning hole on the carrier belt to achieve precise positioning. The positioning hole on the carrier belt is a common design and will not be described in detail.

[0064] See Figure 5 Preferably, a limiting shaft 36 passing through the peeling knife holder 34 is provided next to the fixing frame 31 to achieve precise alignment of the peeling knife 351. Each peeling knife holder 34 is fixedly connected with a protrusion plate 341, and each cutting knife holder 32 is threadedly connected with an adjusting bolt 33 that can abut against the protrusion plate 341. By changing the protruding length of the adjusting bolt 33, the minimum distance between the peeling knife holder 34 and the cutting knife holder 32 can be limited, thereby limiting the range of motion of the peeling knife 351. The user can set a scale corresponding to the adjusting bolt 33 on the cutting knife holder 32 to achieve precise adjustment.

[0065] See Figure 5 Preferably, a limiting plate 37 is fixedly connected to the fixing bracket 31 between the two cutting blade holders 32 to physically limit the cutting blade holders 32 and prevent damage to the cutting blades 321.

[0066] See Figure 3 Preferably, the adjusting screw 252 can be driven by a drive element to achieve automatic adjustment, or it can be turned manually. If it is turned manually, a cross pattern can be provided at the end of the adjusting screw 252.

[0067] See Figures 1-8 Preferably, the wire feeding drive, the adjustment drive 291, the cutting and peeling drive 312, and the unloading drive 543 are all rotary motors, and the pressing drive is a cylinder, which can provide sufficient power.

[0068] See Figure 8Preferably, a contact plate is fixedly connected to the top surface of the guide rail, and multiple positioning steel balls 57 are embedded in the top surface of the contact plate. A lifting spring is provided on the contact plate to abut against the positioning steel balls 57. At the same time, a positioning groove corresponding to the positioning steel balls 57 is provided on the unloading rack plate 51. When stripping and crimping the terminals at the end of the wire harness, the positioning steel balls 57 cooperate with the positioning groove to achieve precise positioning.

[0069] In the implementation of this invention: when it is necessary to adjust the distance between the two guide wheels 25, the adjustment drive 291 is activated, which drives the drive screw 27 to rotate, thereby causing the lifting seat 271 to reach the top of the drive screw 27. At this time, the bending push plate 272 contacts the unlocking plate 26 and pushes the unlocking plate 26 to move towards the cutting and peeling mechanism 3. The unlocking plate 26 cooperates with the elastic locking plate 244, forcing the elastic locking plate 244 to retract into the tension plate 242. At this time, the auxiliary gear 251 disengages from the wire feeding gear 23, and the adjusting screw 252 can be turned to adjust the distance between the two guide wheels 25. After the adjustment is completed, the lifting seat 271 descends, and under the action of the return spring, the tension plate 242 automatically resets, the elastic locking plate 244 cooperates with the locking groove, and the auxiliary gear 251 meshes with the wire feeding gear 23 one-to-one.

[0070] The wire feeding drive is activated, causing the two wire feeding gears 23 to rotate, thereby guiding the guide wheel 25 to feed the wire harness. When the beginning of the wire harness reaches the cutting blade holder 32, the stripping drive 312 is activated, causing the stripping blade holder 34 to move closer to the cutting blade holder 32, and the cutting blade 321 cuts the wire harness. Then, the stripping drive 312 reverses, and the stripping blade holder 34 and the cutting blade holder 32 return to their original positions. At this time, the adjusting drive 291 is activated, causing the lifting seat 271 to descend. The lifting seat 271 enters the first inclined section from the first vertical section of the guide groove 212. Under the action of the guide post and the first inclined section, the rotating seat 213 swings horizontally at a certain angle until the guide post enters the second vertical section. At this time, the beginning of the wire harness is directly facing the stripping blade holder 34, and the roller 273 reaches the wedge block 281 located above. Under the action of the wedge block 281 and the roller 273, the auxiliary plate 28 drives the pushing block 283 to descend, thereby pushing... The wire feeder 22 drives the wire harness to move a certain distance toward the stripper 34, sending the beginning of the wire harness between the strippers 351. Then, the stripping drive 312 is activated, causing the stripper 351 to cut part of the wire insulation at the beginning of the wire harness. Then, the lifting seat 271 continues to descend, and the auxiliary plate 28 reaches the lowest point of its range of motion and can no longer descend. The roller 273 passes through the wedge block 281 located above, and the auxiliary plate 28 rises and resets. The wire feeder 22 also moves and resets, separating the cut wire insulation from the wire harness.

[0071] The lifting seat 271 continues to descend, the guide column enters the second inclined section from the second vertical section, the rotating seat 213 continues to swing at a certain angle along the original direction, so that the beginning of the wire harness is directly facing the crimping box 41. Then the roller 273 cooperates with the wedge block 281 located below, the auxiliary plate 28 descends again, the wire feeder 22 drives the stripped part of the wire harness to move into the conductor crimping cylinder of the terminal, the crimping block 421 descends, and under the cooperation of the top mold 422 and the bottom mold 411, the terminal crimping of the beginning of the wire harness is completed. At the same time, the separating cutter on the top mold 422 and the bottom mold 411 cuts the connecting bridge.

[0072] When the crimping block 421 descends, the lever 425 pushes the swing arm 44 to rotate a certain angle, thereby causing the translation plate 442 to push the conveyor seat 47 to move a certain distance. The positioning pin disengages from the positioning hole, and the rack 471 meshes with the conveyor gear 461. During this process, the ratchet 462 engages with the pawl, driving the conveyor roller 46 to rotate a certain angle, thus moving the carrier belt. When the swing arm 44 returns to its original position, the ratchet 462 disengages from the pawl. During the translation and return process of the conveyor seat 47, the positioning plate 48 is pressed into the guide hole, and the positioning pin engages with the positioning hole to achieve precise positioning of the terminal. Before crimping, there is a safe distance between the terminal and the bottom mold 411. When the top mold 422 descends, it will drive the terminal and the carrier belt to descend synchronously. A carrier belt redundancy is reserved upstream of the top mold 422 (i.e., between the crimping block 421 and the terminal feeding mechanism) so that when the top mold 422 drives the terminal to descend synchronously, the release of this redundancy will compensate for the displacement stroke, thereby keeping the downstream positioning plate 48 in a stationary positioning state during the crimping process.

[0073] After the terminal crimping is completed at the beginning of the wire harness, the lifting seat 271 rises and resets. During continuous operation, limit elements such as light grid switches can be set to prevent the lifting seat 271 from rising to the point where the bending push plate 272 contacts the unlocking plate 26. During the rising process of the lifting seat 271, the rotating seat 213 resets to the point where the wire harness is facing the cutting knife seat 32. The wire feeding drive is started, driving the wire harness to move a distance towards the cutting knife seat 32. Then the clamping cylinder 561 is started to clamp the wire harness, and the cutting knife 321 cuts the wire harness.

[0074] When the unloading drive unit 543 is activated, the first section of the gear teeth on the drive gear 541 meshes with the upper gear 521, causing the rotating shaft 52 to rotate at a certain angle, so that the tail end of the wire harness swings horizontally to correspond with another set of stripping blades 351. At this time, the positioning steel ball 57 engages with one of the positioning slots to position the rotating shaft 52. Then, the drive shaft 54 ​​continues to rotate in the original direction, the first section of the gear teeth on the drive gear 541 disengages from the upper gear 521, and the first section of the gear teeth on the turntable 542 engages with the lower gear 522. The meshing causes the lower gear 522 to rotate 360° (the diameter ratio of the lower gear 522 and the turntable 542 in the attached drawings of this invention does not represent the actual diameter ratio, and the user can adjust it according to the actual situation). When the lower gear 522 rotates 180°, that is, when the driven seat 531 moves from the top end of its range of motion to the bottom end, the translation guide seat 55 moves a distance away from the rotating shaft 52 under the action of the connecting rod 532. At this time, the feeding drive 543 is temporarily stopped, and it is restarted after the wire harness tail end is stripped.

[0075] After stripping the wire harness tail end, the drive shaft 54 ​​continues to rotate, driving the lower gear 522 to rotate another 180°, causing the translation guide 55 to reset. Then, the first tooth area on the turntable 542 disengages from the lower gear 522, and the second tooth area on the drive gear 541 meshes with the upper gear 521, driving the rotating shaft 52 to rotate until the wire harness tail end is facing another crimping box 41. At this time, the positioning steel ball 57 engages with another set of positioning grooves to position the rotating shaft 52. Then, the second tooth area on the drive gear 541 disengages from the upper gear 521, and the second tooth area on the turntable 542 meshes with the lower gear 522, driving the translation guide 55 to reciprocate once, completing the crimping of the wire harness tail end terminal.

[0076] After the crimping of the wire harness tail end terminals is completed, the second tooth area on the turntable 542 disengages from the lower gear 522, and the third tooth area on the drive gear 541 meshes with the upper gear 521, driving the rotating shaft 52 to rotate. This activates the clamping cylinder 561, causing the gripper 562 to release the wire harness. In this device, after the wire harness is cut, the stripping and crimping of the tail end of the previous wire harness and the stripping and crimping of the head end of the next wire harness can be performed simultaneously, improving production efficiency.

[0077] This invention provides a wire harness terminal crimping device, which has the following advantages:

[0078] 1. It integrates multiple processes such as feeding, cutting, stripping, crimping and unloading, realizing continuous operation from wire harness loading to finished product unloading, greatly reducing manual intervention and improving production efficiency;

[0079] 2. By setting up an adjusting screw and guide wheel mechanism, the distance between the two guide wheels can be quickly adjusted to adapt to various diameter wire harnesses, making it easy to make precise adjustments according to process requirements and improving the versatility of the equipment to a certain extent;

[0080] 3. By setting up mechanisms such as rotating seats, lifting seats, guide grooves and wedge blocks, the automatic transfer and precise positioning of wire harnesses between cutting, stripping and crimping stations can be realized, and the ends of two wire harnesses can be crimped synchronously, further shortening the production cycle.

[0081] 4. All mechanisms are integrated on the same base, with a reasonable layout and small space occupation. It adopts motor drive and mechanical linkage control, supports mechanical adjustment and manual fine adjustment, and is convenient for maintenance and debugging.

[0082] In summary, the beneficial effects of this invention are: it not only improves the mechanization and production efficiency of wire harness terminal crimping, but also ensures the stability and consistency of crimping quality through multi-mechanism collaboration and precision control.
