Description

Technical Field

[0001] This invention relates to the field of connector assembly technology, and more specifically to an auxiliary assembly device for automotive wiring harness connectors. Background Technology

[0002] Connector assembly equipment is a specialized piece of equipment or tool designed to improve the efficiency, precision, and consistency of connector plastic housing assembly. Its core function is to ensure accurate alignment, reliable insertion, and locking of the plastic housing, while meeting the automotive industry's requirements for high reliability and mass production. This equipment is an automated or semi-automated assembly system for connector plastic housings (male and female mating structure), covering key processes such as alignment, insertion, and testing to ensure reliable connector connections.

[0003] Chinese patent CN118841808A discloses an automotive wiring harness connector assembly device. The advantages of this invention are that it enables automatic assembly of wiring harness connectors with high efficiency, and performs dimensional inspection after assembly to ensure the consistency of the assembly.

[0004] Chinese patent CN110994322A discloses a wire harness connector assembly line. Through the coordinated use of the whole system, the entire assembly process of the wire harness connector, from material feeding to final product output, is completed by the equipment. This reduces the manpower required at each assembly station and saves the manpower and time spent on manual handling. It also greatly reduces safety hazards during the assembly process, improves assembly efficiency, and ensures product quality.

[0005] Existing connector assembly equipment is divided into manual assembly and automated assembly. Manual assembly is much slower than automated equipment, which can become a bottleneck, especially in mass production. The male and female connector shells are assembled by engaging with corresponding slots, recesses, or guides (female ends) using cantilevered hooks, spherical protrusions, or trapezoidal protrusions on the shells. The elastic deformation of the plastic is used to achieve springback locking after engagement. When assembling connectors, workers perform initial assembly checks or spot checks by visual inspection. The assembly effect is easily affected by fatigue and skill level, and improper operation may lead to problems such as incomplete engagement, misalignment, and missing parts, increasing the cost of subsequent quality inspection. Although automated assembly equipment greatly improves the efficiency and consistency of connector assembly, the investment cost is high, which is difficult for small and medium-sized enterprises to afford. Precision components such as connectors still rely on manual re-inspection, and the equipment maintenance time is long.

[0006] Therefore, the present invention provides an auxiliary assembly device for automotive wiring harness connectors that can automate connector assembly and improve connector assembly efficiency. Summary of the Invention

[0007] To address the problems of high cost, reliance on manual inspection, low worker assembly efficiency, and high subsequent quality inspection costs in existing automated assembly equipment, an auxiliary assembly device for automotive wiring harness connectors is designed.

[0008] The technical solution adopted by this invention to solve its technical problem is: an auxiliary assembly device for automotive wiring harness connectors, including an annular guide rail, an upper clamping plate fixedly connected to the outer side of the annular guide rail, a lower clamping plate rotatably connected to the outer side of the annular guide rail, and clamps detachably connected to the bottom of the upper clamping plate and the top of the lower clamping plate, a lifting column drivingly connected to the bottom of the annular guide rail, and a detection component detachably connected to the top of the annular guide rail; the clamp includes a clamp housing detachably connected to the upper or lower clamping plate, and when the connector is pushed into the inside of the clamp, the connector pushes the unidirectional shaft slidably connected inside the clamp housing to rotate unidirectionally while clamping and fixing it, by pushing the connector into the clamp housing... The push rod, which is slidably connected to one side of the connector, moves the one-way shafts away from each other, thus loosening the connector. The lifting column, driven by a connecting rod connected to one side of the annular guide rail during connector assembly, pushes the clamp on the top of the lower clamp plate to rise, causing the male and female plastic shells of the connector to move towards each other for assembly. The detection assembly includes a detection housing detachably connected to the top of the annular guide rail. After the connector is assembled, it applies a horizontal force to the connector's engagement point through an elastic element six located inside the detection housing and a detection block fixed to one side of the elastic element six. The detection block, in conjunction with the annular guide rail, presses against the connector's engagement point, separating any loose connectors.

[0009] Furthermore, the lower clamping plate includes a flipping gear rotatably connected to the annular guide rail. A base is fixedly connected to the side of the flipping gear away from the annular guide rail. A bottom plate is slidably connected to the inner side of the base.

[0012] Furthermore, a fixed platform is fixedly connected to the bottom of the annular guide rail. A rocker arm is rotatably connected to the side of the fixed platform away from the annular guide rail. A connecting rod is rotatably connected to the outside of the rocker arm. A crank is rotatably connected to the end of the connecting rod away from the rocker arm. The crank is rotatably connected to the fixed platform. The connecting rod is rotatably connected to the lifting column. A gear set is fixedly connected to the inside of the crank. The gear set consists of three gears meshing in pairs. Each gear is rotatably connected to the bottom of the annular guide rail. A bevel gear is fixedly connected to one side of the middle gear. The bevel gear meshes with another bevel gear fixedly connected to the transmission shaft at the bottom of the annular guide rail.

[0013] Furthermore, the detection assembly also includes a slide groove on the upper part of the detection housing, a detection block slidably connected to the inner side of the slide groove, a transmission rod fixedly connected to the top of the detection block, a rack block slidably connected to the inner side of the slide groove, an elastic element six fixedly connected to the rack block on the side near the detection block, a transmission assembly drivingly connected to the bottom of the rack block, an adjusting rod rotatably connected to the side of the rack block away from the elastic element six, the adjusting rod being threadedly connected to the detection housing, a material discharge chute on the bottom of the detection housing, and a conveyor belt assembly placed at the bottom of the detection assembly.

[0014] Furthermore, the side of the detection block away from the slide is set as an inclined surface, and a knob is fixedly connected to the end of the adjusting rod away from the rack block. Rotating the knob can make the rack block and the detection block move closer or further apart.

[0015] Furthermore, a vibratory feeder is placed on one side of the annular guide rail, and a discharge port is fixedly connected to one side of the vibratory feeder. A feeding assembly is fixedly connected to the end of the discharge port away from the vibratory feeder. Two sets of vibratory feeders and feeding assemblies are provided, with one vibratory feeder located on top of the other.

[0016] Furthermore, each feeding assembly includes a feeding base fixedly connected to the outside of the discharge port, a pressure plate rotatably connected to the inside of the feeding base, a support leg connected to the middle of the pressure plate, an elastic element four fixedly connected to the outside of the support leg, the elastic element four fixedly connected to the feeding base, the support leg slidably connected to the feeding base, a separating pin slidably connected to the middle of the feeding base, the support leg slidably engaging with the separating pin, and an elastic element five fixedly connected to the side of the separating pin away from the discharge port, the elastic element five fixedly connected to the feeding base.

[0018] The beneficial effects of this invention are:

[0019] The automotive wiring harness connector auxiliary assembly equipment described in this invention uses dynamic compression by elastic elements and adjustable knobs to set the engagement strength. Its simple and reliable mechanical structure allows for the selection of connectors that meet the engagement strength requirements, avoiding problems such as incomplete engagement, misaligned assembly, and missing components. The detection blocks on both sides, working in conjunction with the annular guide rail, simultaneously compress the engagement point of the connector, ensuring uniform force on both sides during compression. This prevents plastic deformation or breakage of the latch due to excessive pressure on one side, guaranteeing the stability and consistency of the test results. The detection blocks push the lower connector shell to fall, and the transmission rod on the detection blocks pushes the push rod on the fixture, separating the loose upper connector shell. The separated connector falls from the drop chute onto a conveyor belt set placed below the testing assembly. The conveyor belt set can collect incompletely engaged connector shells, improving the overall process continuity and enhancing the connector assembly effect and efficiency.

[0033] To make the technical means, technical features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example: Figures 1-11As shown, the automotive wiring harness connector auxiliary assembly equipment of the present invention includes an annular guide rail 1. The annular guide rail 1 can be a conventional general-purpose model, but in order to ensure the operational stability of the annular guide rail 1, it can also be configured as an upper and lower double base plate structure with double tracks on the inner side, both driven by chains, and the outer side is provided with upper and lower connected workstations. Multiple workstations are provided, which are all existing technologies and will not be described in detail here. An upper clamping plate 2 is fixedly connected to the outer workstation of the annular guide rail 1, and a lower clamping plate 3 is rotatably connected to the outer side of the annular guide rail 1. The bottom of the upper clamping plate 2 and the top of the lower clamping plate 3 are detachably connected to clamps 4. A lifting column 12 is drivenly connected to the bottom of the annular guide rail 1, and a detection component 8 is detachably connected to the top of the annular guide rail 1. The clamp 4 includes a clamp housing 41 detachably connected to the upper clamping plate 2 or the lower clamping plate 3. When the connector is pushed into the inner side of the clamp 4, the connector pushes the clamp. The unidirectional shaft 42, which is slidably connected to the inner side of the housing 41, rotates in one direction while clamping and fixing it. By pushing the push rod 48, which is slidably connected to one side of the clamp housing 41, the unidirectional shafts 42 are moved away from each other, thus releasing the connector. The lifting column 12 is driven by the connecting rod 11, which is connected to one side of the annular guide rail 1, during connector assembly. It pushes the clamp 4 on the top of the lower clamping plate 3 to rise, so that the male and female plastic shells of the connector move towards each other for assembly. The detection assembly 8 includes a detection housing 81 that is detachably connected to the top of the annular guide rail 1. After the connector is assembled, it applies a horizontal force to the engagement point of the connector through the elastic element 83 set inside the detection housing 81 and the detection block 82 fixed to one side of the elastic element 83. The detection block 82, in conjunction with the annular guide rail 1, squeezes the engagement point of the connector, separating the unlocked connector.

[0035] Specifically, during connector assembly, the lifting column 12 lifts the base plate 33 and the clamp 4 on the base plate 33. The clamp 4 moves the connector housing upward for assembly. When the assembled connector moves to the detection component 8 along the annular guide rail 1, the detection blocks 82 on both sides cooperate with the guide rail to simultaneously squeeze the locking part of the connector, separating the unlocked connector to meet the requirements of testing the mechanical connection strength of the connector.

[0036] In this embodiment, the lower clamping plate 3 includes a flipping gear 31 that is rotatably connected to the annular guide rail 1. A base 32 is fixedly connected to the side of the flipping gear 31 away from the annular guide rail 1. A base plate 33 is slidably connected to the inner side of the base 32. An annular plate 34 is fixedly connected to the end of the base plate 33 away from the flipping gear 31. A spring is fixedly connected to the inner side of the base 32. The other end of the spring is fixedly connected to the base plate 33.

[0037] Specifically, such as Figures 1-5 , Figure 7 , Figure 9 and Figure 11As shown, when the lifting column 12 pushes the base plate 33 and the clamp 4 on the base plate 33 to move upward, the annular plate 34 pushes the push rod 48 on the side of the clamp housing 41 to make the clamp 4 release the connector plastic shell and push it to move upward until it engages with another connector plastic shell on the upper clamping plate 2. When the lifting column 12 descends, the spring fixedly connected to the inner side of the base 32 pushes the base plate 33 to reset, reducing the possibility of connector damage caused by the slow reset of the base plate 33.

[0038] In this embodiment, a circular fixing block is fixedly connected to the outer side of the annular guide rail 1. The circular fixing block is rotatably connected to the flip gear 31. A symmetrical cylindrical groove is provided on the circular fixing block. An elastic element 36 is fixedly connected inside the cylindrical groove. A locking block 35 is slidably connected inside the cylindrical groove. The locking block 35 is fixedly connected to the elastic element 36. A locking groove is provided inside the flip gear 31. The locking groove and the locking block 35 are slidably engaged. A rack is fixedly connected to both sides of the annular guide rail 1. The rack meshes with the flip gear 31.

[0039] Specifically, such as Figures 1-2 and Figure 7 As shown, the flip gear 31 meshes with the racks fixedly connected to both sides of the annular guide rail 1 during its movement. The flip gear 31 rotates around the circular fixed block, causing the lower clamping plate 3 to rotate to be opposite the upper clamping plate 2. The elastic element 36 pushes the locking block 35 to engage with the locking slot, thereby radially limiting the flip gear 31 and reducing the possibility that the lower clamping plate 3 may deflect during the connector loading and assembly process, affecting the assembly effect and efficiency.

[0040] In this embodiment, the one-way shaft 42 is fixedly connected to the elastic element 43 on both sides, the clamp housing 41 is fixedly connected to the other end of the elastic element 43, the one-way shaft 42 is rotatably connected to the two ends of the one-way shaft 42, the end of the rotating plate 44 away from the one-way shaft 42 is rotatably connected to the cylindrical pin 45, the outer side of the cylindrical pin 45 is fixedly connected to the elastic element 46, the elastic element 46 is fixedly connected to the clamp housing 41, the push rod 48 is slidably engaged with the two sides of the cylindrical pin 45, and the clamp housing 41 is fixedly connected to the inner side of the clamp housing 41.

[0041] Specifically, such as Figures 1-6 and Figure 9As shown, when the feeding assembly 5 lifts the connector housing upwards, the connector housing is pushed into the inside of the clamp 4 on the upper clamping plate 2. While the one-way shaft 42 is pushed to rotate in one direction by the connector housing, the elastic element 43 applies a thrust to it, causing the one-way shaft 42 to clamp and fix the connector housing. When the lifting column 12 pushes the base plate 33 and the clamp 4 upwards, the push rod 48 on the side of the clamp 4 is pressed into the inside of the clamp 4 by the annular plate 34. The movement of the push rod 48 drives the cylindrical pin 45 to move towards the one-way shaft 42. The rotating plate 44 rotates accordingly and pushes the one-way shaft 42 to move outwards. The connector housing is released and moves upwards with the limiting plate 47 to engage with another connector housing on the upper clamping plate 2, preventing the clamp 4 on the lower clamping plate 3 from dragging and damaging the assembled connector. When the lifting column 12 descends, the elastic element 43 pushes the one-way shaft 42 to move towards the opposite side to reset, and the elastic element 46 pushes the cylindrical pin 45 to reset.

[0042] In this embodiment, a fixed platform is fixedly connected to the bottom of the annular guide rail 1. A rocker arm 9 is rotatably connected to the side of the fixed platform away from the annular guide rail 1. A connecting rod 11 is rotatably connected to the outside of the rocker arm 9. A crank 10 is rotatably connected to the end of the connecting rod 11 away from the rocker arm 9. The crank 10 is rotatably connected to the fixed platform. The connecting rod 11 is rotatably connected to the lifting column 12. A gear set is fixedly connected to the inside of the crank 10. The gear set consists of three gears meshing in pairs. Each gear is rotatably connected to the bottom of the annular guide rail 1. A bevel gear is fixedly connected to one side of the middle gear. The bevel gear meshes with another bevel gear fixedly connected to the transmission shaft at the bottom of the annular guide rail 1.

[0043] Specifically, such as Figures 2-3 As shown, when the connector housing moves above the lifting column 12, the bevel gear fixedly connected to the transmission shaft at the bottom of the annular guide rail 1 drives the bevel gear fixedly connected to the gear set to rotate. The crank 10 rotates with the gear set, causing the connecting rod 11 to perform a complex planar motion. The connecting rod 11 drives the lifting column 12 to push the base plate 33 and the clamp 4 on the base plate 33 to move upward, lifting the connector housing and engaging it with another connector housing.

[0044] In this embodiment, the detection assembly 8 further includes a slide groove on the upper part of the detection housing 81, a detection block 82 slidably connected to the inner side of the slide groove, a transmission rod fixedly connected to the top of the detection block 82, a rack block 84 slidably connected to the inner side of the slide groove, an elastic element 83 fixedly connected to the side of the rack block 84 near the detection block 82, a transmission assembly 85 drivingly connected to the bottom of the rack block 84, an adjusting rod 86 rotatably connected to the side of the rack block 84 away from the elastic element 83, the adjusting rod 86 being threadedly connected to the detection housing 81, a material discharge groove being provided at the bottom of the detection housing 81, and a conveyor belt assembly 7 being placed at the bottom of the detection assembly 8.

[0045] Specifically, such as Figures 1-3 and Figure 8As shown, when the clamp 4 moves to fit against the conveyor belt group 7, the connector shell completes the snap-fit. When the snap-fit ​​connector moves with the annular guide rail 1 to the detection component 8, the detection component 8 moves in coordination with the annular guide rail 1, causing the detection blocks 82 on both sides to simultaneously press the snap-fit ​​point of the connector, causing the lower connector shell to fall off. The transmission rod on the detection block 82 pushes the push rod 48 on the clamp 4 to separate the unlocked upper connector shell. The unlocked and automatically detached connector and the separated connector fall from the drop chute onto the conveyor belt group 7 placed below the detection component 8. When the properly snap-fit ​​connector passes through, the detection block 82 is pushed away by the connector and moves away from the connector along the slide groove. When the squeezing force of the detection block 82 on the connector is adjusted, the transmission component 85 can drive the rack blocks 84 on both sides to move relative to each other, so that the connector is evenly stressed on both sides, avoiding plastic deformation or breakage of the snap-fit ​​caused by unilateral overpressure.

[0046] In this embodiment, the side of the detection block 82 away from the slide groove is set as an inclined surface, and a knob is fixedly connected to the end of the adjusting rod 86 away from the rack block 84. Rotating the knob can make the rack block 84 and the detection block 82 move closer or further apart.

[0047] Specifically, such as Figures 1-3 and Figure 8 As shown, when it is necessary to adjust the squeezing force of the detection block 82 on the connector, rotate the knob to move the adjusting rod 86 along the threaded hole on the detection housing 81. When the knob is rotated clockwise, the adjusting rod 86 drives the rack blocks 84 on both sides to move closer to each other, increasing the degree of compression of the elastic element 83 by the rack blocks 84 and the detection block 82, increasing the elastic force applied by the elastic element 83 to the detection block 82, thereby increasing the squeezing force of the detection block 82 on the connector. When the knob is rotated counterclockwise, the adjusting rod 86 drives the rack blocks 84 on both sides to move away from each other, reducing the degree of compression of the elastic element 83 by the rack blocks 84 and the detection block 82, reducing the elastic force applied by the elastic element 83 to the detection block 82, thereby reducing the squeezing force of the detection block 82 on the connector, so as to meet the requirement that the detection assembly 8 can detect different clamping strengths.

[0048] In this embodiment, a vibratory feeder 6 is placed on one side of the annular guide rail 1, and a discharge port is fixedly connected to one side of the vibratory feeder 6. A feeding assembly 5 is fixedly connected to the end of the discharge port away from the vibratory feeder 6. Two sets of vibratory feeders 6 and feeding assemblies 5 are provided, with one vibratory feeder 6 located on top of the other.

[0049] Specifically, such as Figures 1-2 and Figure 10 The connector assembly materials are placed into the corresponding vibratory feeders 6. The connector shells move with the vibratory feeders 6 to the feeding assembly 5 at the discharge port. The conveyor belt group 7 can recycle the connector shells that are not fully engaged.

[0050] In this embodiment, each feeding assembly 5 includes a feeding base 51 fixedly connected to the outside of the discharge port. A pressure plate 52 is rotatably connected to the inside of the feeding base 51. A support leg 53 is drivenly connected to the middle of the pressure plate 52. An elastic element 54 is fixedly connected to the outside of the support leg 53. The elastic element 54 is fixedly connected to the feeding base 51. The support leg 53 is slidably connected to the feeding base 51. A separation pin 55 is slidably connected to the middle of the feeding base 51. The support leg 53 is slidably engaged with the separation pin 55. An elastic element 56 is fixedly connected to the side of the separation pin 55 away from the discharge port. The elastic element 56 is fixedly connected to the feeding base 51.

[0051] Specifically, such as Figures 1-2 , Figure 6 and Figure 10 As shown, the pressure plate 52 rotates to push the support leg 53 to move. The support leg 53 drives the separation pin 55 to move closer or further away from each other, intermittently pushing the connector on the discharge port to meet the needs of automatic intermittent feeding of the equipment.

[0052] In this embodiment, a fixed platform is slidably connected to the inner side of the feeding base 51, and a fixed block 57 is detachably connected to the top of the fixed platform. A push plate 58 is slidably connected to the side of the fixed platform near the feeding port. A hydraulic cylinder 59 is fixedly connected to the outer side of the vibrating plate 6, and the output end of the hydraulic cylinder 59 is fixedly connected to the push plate 58.

[0053] Specifically, such as Figures 1-2 , Figure 6 and Figure 10 As shown, the hydraulic cylinder 59 drives the push plate 58 to rise and reset. The push plate 58 and the fixed block 57 work together to limit the connector shell on the top of the fixed platform, reducing the possibility of the connector falling. When the push plate 58 rises to a certain height, it drives the fixed platform to rise together. The rise of the fixed platform causes the pressure plate 52 to rotate and push the support leg 53 to slide inside the upper material base 51. The support leg 53 drives the separation pin 55 to move away from each other, so that the connector on the discharge port is pushed forward. When the fixed platform falls, the elastic element 4 54 pushes the pressure plate 52 to pop out. The support leg 53 moves with the pressure plate 52. The support leg 53 and the elastic element 56 push the separation pin 55 to move closer to each other, squeezing a connector shell close to the fixed platform and moving it to the top of the fixed platform, while intercepting other connector shells.

[0054] Working principle: When assembling connectors, the male and female connector shell materials are first placed into the corresponding vibratory feeders 6. Before the lower clamping plate 3 enters the feeding area, the lower clamping plate 3 rotates to be in the same direction as the upper clamping plate 2. The shell moves to the discharge port with the vibratory feeder 6. The push plate 58 pushes the fixed platform to rise, causing the separating pins 55 to move away from each other. The connector shell is lifted and fixed on the clamp 4. When the fixed platform descends, the separating pins 55 move closer to each other, squeezing one connector shell that is close to the fixed platform, causing it to move to the top of the fixed platform, and intercepting other connector shells.

[0055] Then the connector housing moves with the ring guide rail 1. The lower clamping plate 3 rotates to be opposite the upper clamping plate 2 during the movement. When the connector housing moves above the lifting column 12, the lifting column 12 lifts the base plate 33 and the clamp 4 on the base plate 33. The connector housing is released and moves upward with the clamp 4 to engage with another connector housing on the upper clamping plate 2.

[0056] Finally, when the snap-fit ​​connector moves to the detection component 8 along the annular guide rail 1, the detection component 8 moves in coordination with the annular guide rail 1, causing the detection block 82 to press the connector's snap-fit ​​point, causing the lower connector shell to fall off. The transmission rod on the detection block 82 pushes the push rod 48 on the clamp 4 to separate the unlocked upper connector shell. The separated connector falls from the drop chute onto the conveyor belt group 7 placed below the detection component 8. The conveyor belt group 7 can transport the sorted connector shells back to the vibratory feeder 6. The locked connector is transported to the next process along the guide rail. When it is necessary to adjust the squeezing pressure of the detection block 82, turn the knob forward to increase the squeezing pressure of the detection block 82 on the connector, and turn the knob backward to decrease the squeezing pressure of the detection block 82 on the connector.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
