Description

Technical Field

[0001] The present invention relates to the technical field of intelligent wire harness production and manufacturing, and in particular to a terminal shell penetration device and method. Background Art

[0002] Terminal threading technology is a key process in the production of smart wiring harnesses. During the manufacturing process, the cable cores must be reliably connected to the terminals to form a stable electrical transmission path. Typically, the cores are crimped to the terminals, and then multiple terminals are threaded through the outer shell to complete the electrical connection between the cable and the external device or system. This process is crucial to the performance of smart wiring harnesses, as it affects the electrical transmission stability, interference resistance, and mechanical strength of the harness.

[0003] As attached Figure 1 As shown in the figure, a wiring harness contains two wire cores, each of which requires a terminal. Both terminals are then threaded into the same housing. However, during installation, since the terminals are fed in the same direction, this can cause inconvenience when installing them inside the housing. To accommodate this, additional mechanical means are often required to adjust the angle of the terminals to ensure they are correctly positioned. This process not only increases production costs but can also affect installation efficiency and product stability.

[0004] To overcome the shortcomings of the existing technology, the present invention proposes a new terminal insertion device and method, aiming to solve the problem of the existing technology that the terminal direction cannot be automatically adjusted. The device and method of the present invention improve production efficiency, reduce production costs, and ensure the installation accuracy and stability of the terminal. Summary of the Invention

[0007] In some embodiments of the present invention, the wire harness feeding mechanism includes a feeding clamp for clamping the wire core, and the feeding clamp has two wire core notches, and the two wire core notches are arranged at intervals.

[0008] In some embodiments of the present invention, the wire core rotation assembly includes a rotating drive member, a first gear fixedly connected to the output end of the rotating drive member, a second gear meshing with the first gear, and a wire core rotating member fixedly connected coaxially with the first gear and the second gear respectively.

[0009] In some embodiments of the present invention, the wire core rotating member has an arc-shaped guide surface at its opening, and the wire core rotating member has an accommodating groove adapted to the shape of the terminal.

[0010] In some embodiments of the present invention, the terminal clamp has a clamping groove with the same shape as the outer wall of the terminal, and the clamping end of one clamping groove close to the other clamping groove also has a width positioning block. When the two terminal clamps are close to each other, the width positioning block fits with the end of the other clamping groove.

[0011] In some embodiments of the present invention, the terminal clamp includes a first clamp arm and a second clamp arm, and the first clamp arm and the second clamp arm both have a first bend and a second bend at the same angle, and the first clamp arm and the second clamp arm are in contact with each other between the first bend and the second bend.

[0012] In some embodiments of the present invention, the terminal clamp also has a guide assembly connected to the terminal clamp, including a vertical guide member for guiding the first clamp arm and the second clamp arm to move relatively closer or farther away, and a horizontal guide member for guiding the two terminal clamps to move relatively closer or farther away.

[0013] In some embodiments of the present invention, the shell clamping assembly includes a slider that can be relatively slidably arranged between the vibration disk and the wiring harness clamping assembly, and a shell clamping claw that can be relatively opened and closed on the slider, and the shell clamping claw is used to clamp the shell on the vibration disk.

[0014] In some embodiments of the present invention, the wire harness clamping assembly includes wire core clamping jaws with square wire clamping slots that can be opened and closed relative to each other, and is used to clamp the wire core after being rotated to a certain angle.

[0015] According to a second aspect of the present invention, a terminal shell insertion method is also provided, comprising the following steps: The wire harness with terminals is transferred to the wire harness fixing clamp by using the wire harness feeding mechanism; The wire core is rotated at an angle by the wire core rotating assembly; The transfer mechanism is used to move the wire harness on the wire harness fixing clamp to the wire harness clamp, and the terminal clamp is displaced at the terminal clamp to move the two terminals to a set distance; Moving the wire harness on the wire harness clamping claw to the wire harness clamping assembly by the transfer mechanism; The shell clamping assembly moves to the output port of the shell feeding mechanism to clamp the shell, and the wire harness clamping assembly approaches the shell clamping assembly to assemble and clamp the wire harness and the shell; The wire harness on the wire harness clamping assembly is transferred to the detection mechanism by the transfer mechanism, and the assembled wire harness is tested for quality.

The coordination of the wire core width adjustment mechanism and the shell assembly mechanism further ensures the precise operation of the terminal clamping assembly and the shell clamping assembly when adjusting the terminal spacing and installation angle. This not only ensures stable positioning of the terminals, but also uses the detection mechanism to monitor the installation status in real time, avoiding deviations and problems caused by improper angles or positions during installation. Compared with traditional technologies, the present invention significantly improves the accuracy and efficiency of the production process by introducing multiple automated adjustment and detection mechanisms, reducing manual intervention and error rates.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] As mentioned in the background technology, during the production of wire harnesses, the wire cores are terminated. Since the terminals are input in the same direction, the termination direction is also the same. However, when the terminals are installed into the housing, the terminals have protrusions that engage with the housing. The protrusions must first be rotated 90 degrees to engage with the housing before installation is complete. To ensure accurate connection between the terminals on the wire cores and the housing, the distance between the two wire cores must be shifted after rotation to align the width between the two wire cores with the notch inside the housing. Therefore, a device is needed to solve this technical problem and automate this device.

[0024] like Figures 2 to 11 The terminal penetration device shown includes: Wire harness feeding mechanism 1, used for conveying wire harness with terminals to the processing position; The wire core rotation mechanism 2 includes a wire harness fixing clamp 21 for fixing the wire harness, and a wire core rotation assembly 22 for rotating the wire core angle. It should be noted that the wire core rotation assembly 22 can be driven by a servo motor, a stepper motor, or other drivable motor. It should also be noted that the wire core transfer assembly can rotate the wire core by clamping the wire core with a clamp, by fixing the wire core and then rotating it, or by other methods that can rotate the wire core.

[0025] The wire core width adjustment mechanism 3 includes two terminal clamps 31 for clamping the terminals respectively, a driving assembly 32 for driving the terminal clamps 31 toward each other to move closer or farther away from each other, and a wire harness clamp 33 fixedly connected to the outside of the driving assembly 32 for clamping the wire harness; The shell feeding mechanism 4 includes a vibration plate 41; The housing assembly mechanism 5 includes a housing clamping assembly 51 that can be relatively moved closer to or farther away from the output port of the vibration disk 41, and a wiring harness clamping assembly 52 fixedly connected to the housing clamping assembly 51; Detection mechanism 6, used to detect the installation status of the housing and terminals; There are two transfer mechanisms 7 , one for transferring the wire harness between the wire core rotating mechanism 2 , the wire core width adjusting mechanism 3 and the shell assembling mechanism 5 , and the other for transferring the wire harness between the shell assembling mechanism 5 and the detecting mechanism 6 .

[0026] The present invention ensures the correct matching and efficient installation of the terminal and the shell by integrating the wire harness feeding mechanism 1, the wire core rotating mechanism 2, the wire core width adjustment mechanism 3, the shell feeding mechanism 4, the shell assembly mechanism 5, the detection mechanism 6 and the transfer mechanism 7. First of all, the design of the wire harness feeding mechanism 1 and the shell feeding mechanism 4 solves the problem of accurate docking of the terminal and the shell, which greatly improves the degree of automation of the production process and avoids the instability caused by manual operation in traditional processes. The wire core rotating mechanism 2 effectively adjusts the angle of the terminal through the wire core rotating assembly 22, so that the two terminals can be clamped in the correct installation position when passing through the shell, thereby improving production efficiency and reducing the generation of errors. The cooperation between the wire core width adjustment mechanism 3 and the shell assembly mechanism 5 further ensures the precise operation of the terminal clamping assembly and the shell clamping assembly 51 when adjusting the terminal spacing and installation angle, which not only ensures the stable positioning of the terminal, but also detects the installation status in real time through the detection mechanism 6, avoiding deviations and problems caused by improper angles or positions during the installation process. Compared with traditional technologies, the present invention significantly improves the accuracy and efficiency of the production process and reduces manual intervention and error rates by introducing multiple automated adjustment and detection mechanisms.

[0027] like Figure 2 、 Figure 3 、 Figure 8As described, the wire harness feeding mechanism 1 includes a feeding clamp 11 for clamping the wire core, and the feeding clamp 11 has two wire core notches 11a, and the two wire core notches 11a are spaced apart. The present invention designs the wire harness feeding mechanism 1 as a special feeding clamp 11 with two wire core notches 11a spaced apart, so that the device can synchronously clamp and accurately define the parallel spacing of the two wire cores in one closing action, and the spacing is consistent with the subsequent double-cavity spacing of the shell, realizing the primary precise positioning of "loading is spacing, and positioning is alignment". Compared with traditional processes, this structure eliminates the need for secondary correction mechanisms and time, significantly shortens the whole machine cycle, improves positioning accuracy, and reduces the cumulative risk of wire core surface damage and terminal posture errors, thereby improving the efficiency, yield and reliability of intelligent wire harness assembly as a whole.

[0028] like Figure 4 、 Figure 8 、 Figure 9 As shown, the wire core rotation assembly 22 includes a rotation drive member 22a, a first gear 22b fixedly connected to the output end of the rotation drive member 22a, a second gear 22c meshing with the first gear 22b, and a wire core rotation member 22d fixedly connected coaxially with the first gear 22b and the second gear 22c. The meshing of the first gear 22b and the second gear 22c provides synchronous or opposite rotation. This structure can bring more precise wire core rotation movement. Compared with the traditional design, the gear matching can reduce errors and ensure greater stability. In the assembly of smart wire harnesses with two terminals and the same shell, the most common problem is how to rotate the two wire cores to predetermined different directions within a very short cycle: the traditional approach is either manual flipping or equipping each wire core with a set of independent servo mechanisms, which takes up space and is prone to synchronization errors. The present invention adopts a meshing structure of "rotating driving member 22a-first gear 22b-second gear 22c+coaxial core rotating member 22d" in the core rotating assembly 22: the driving member only needs to output power once to directly drive one of the cores through the first gear 22b, and at the same time, through gear meshing, the second gear 22c allows the other core to be synchronously driven in the opposite direction, ensuring that the two terminals complete rotation at the same time.

[0029] Continue to refer Figure 4 、 Figure 8 、 Figure 9The opening of the core rotating part 22d is provided with an arc-shaped guide surface 22e, and the interior of the core rotating part 22d is provided with a receiving groove 22f adapted to the shape of the terminal. In the existing automated flipping process, the terminal is often pushed into the rotating clamp in a free state. Due to the sharp edges and small dimensional margin of the entrance, a slight deviation will cause jamming or scratching of the coating, which not only slows down the process but also buries contact hazards. The present invention designs a continuous arc-shaped guide surface 22e at the opening of the core rotating part 22d, and opens a receiving groove 22f that precisely fits the terminal shape inside. The purpose is to use the "funnel" effect of the arc surface to achieve self-guiding and self-centering of the terminal, so that the terminal slides into the matching groove at the moment of entry and is locked in position by the groove wall. On the one hand, it completely eliminates the defects of traditional right-angle clamps that are easy to collide and scratch, and the surface integrity rate of the terminal is significantly improved; on the other hand, the terminal is rigidly wrapped in the receiving groove 22f, and no micro-slip or deflection occurs when the rotating part is driven, ensuring the success rate of subsequent shell insertion. Therefore, compared with traditional flat or rectangular jaws, the combination of arc guide and precision accommodation not only optimizes the smoothness of loading, but also takes into account terminal protection and positioning accuracy at high speeds.

[0030] like Figure 5 、 Figure 6 As shown, the terminal clamp 31 has a clamping groove 31a with the same shape as the outer wall of the terminal. The end of the clamping groove 31a of one clamping groove 31a close to the other clamping groove 31a also has a width positioning block 31b. When the two terminal clamps 31 are close, the width positioning block 31b fits with the end of the other clamping groove 31a. The present invention has a clamping groove 31a with the same contour as the outer wall of the terminal on the inner side of the terminal clamp 31, and adds a width positioning block 31b at the end of one clamping groove close to the other clamping groove. When the two clamps are closed, the positioning block forms a rigid fit with the end face of the opposite clamping groove 31a, naturally limiting the center distance between the two terminals. Its purpose is to combine the two steps of "clamping and distance adjustment" into one step - once the clamps are closed, the two terminals are not only enveloping and positioned, but the spacing is also automatically locked to the design value consistent with the housing cavity distance, without the need for additional measuring tools or visual compensation. The terminals remain strictly parallel and spaced constantly throughout the entire handling, flipping, and shell insertion process, ensuring stable insertion force and significantly reducing the risk of scratching. Compared to traditional flat-jaw clamping solutions, this structure also improves positioning accuracy, production efficiency, and product reliability.

[0031] In some embodiments of the present invention, Figure 7As shown, the terminal clamp 31 includes a first clamp arm 31c and a second clamp arm 31d. The first clamp arm 31c and the second clamp arm 31d each have a first bend 31c1 and a second bend 31c2 at the same angle. The first clamp arm 31c and the second clamp arm 31d are in contact with each other between the first bend 31c1 and the second bend 31c2. In traditional clamp structures, the left and right clamp arms are usually straight or only bend on one side. When clamping, the force is uneven, the terminal is prone to offset and local stress concentration, which not only affects the accuracy but also shortens the life of the clamp. Based on this background, the present invention designs the first clamp arm 31c and the second clamp arm 31d to have a first bend 31c1 and a second bend 31c2 at the same angle, and forms a surface-to-surface contact between the two bends. The clamping force is evenly distributed along the outer wall of the terminal, significantly reducing the risk of plating scratches and deformation; at the same time, the spatial complementary structure after bending can offset the accumulated deformation caused by the long-term opening and closing of the clamping jaws, making the positioning accuracy and repeat life better than traditional single-bend or straight-arm solutions.

[0032] Continue to refer Figure 7 As shown, the terminal clamping jaw 31 further includes a guide assembly 31e connected to the terminal clamping jaw 31, including a vertical guide member 31e1 that guides the first clamping arm 31c and the second clamping arm 31d toward or away from each other, and a transverse guide member 31e2 that guides the two terminal clamping jaws 31 toward or away from each other. The vertical guide member 31e1 drives the opening and closing of the terminal clamping jaw 31, while the transverse guide member 31e2 drives the two terminal clamping jaws 31 toward or away from each other.

[0033] like Figure 10 As shown, the shell clamping assembly 51 includes a slider 51a that can slide relatively between the vibration disk 41 and the harness clamping assembly 52, and a shell clamping claw 51b that can open and close relatively on the slider 51a. The shell clamping claw 51b is used to clamp the shell on the vibration disk 41. The present invention adds a slider 51a that can slide relatively between the vibration disk 41 and the harness clamping assembly 52, and arranges a shell clamping claw 51b that can open and close on the slider 51a: the slider 51a is responsible for completing the linear transition of the shell along the assembly axis, avoiding the posture deviation caused by multi-axis transportation; the clamping claw closes at the starting point of the slider 51a's stroke, accurately covers the shell, and opens to put the shell in place after forming a coaxial docking with the harness clamping assembly 52 at the end of the stroke. The purpose of this design is to integrate the three actions of "material collection, transportation, and positioning" into a controlled linear motion chain, while isolating the influence of the micro-vibration of the vibration disk 41 on the subsequent assembly accuracy. Compared with traditional multi-joint robot solutions, the slider 51a-gripper integrated structure is more compact and lower in cost, and can still ensure the constant shell posture at high speeds, providing a more stable and reliable supply link for the efficient and automated assembly of intelligent wiring harnesses.

[0034] like Figure 11As shown, the wire harness clamping assembly 52 includes relatively openable wire core clamping jaws 52a having square wire clamping slots 52a1, which are used to clamp the wire core after rotation. The present invention utilizes openable wire core clamping jaws 52a in the wire harness clamping assembly 52, and processes square wire clamping slots 52a1 within the clamping jaws, so that the wire core is rigidly limited on all four sides, achieving face-to-face, enveloping clamping. This is intended to immediately lock the wire core's posture with high stability after rotation adjustment is completed, preventing secondary displacement or torsion. At the same time, the equidistant support of the square slots disperses the clamping force, protecting the wire core's insulation layer from concentrated pressure.

[0035] According to the second aspect of the present invention, a terminal shell insertion method is also provided. Figure 12 As shown in , the following steps are included: S10: Using the wire harness feeding mechanism 1 to transfer the wire harness with the terminal to the wire harness fixing clamp 21; S20: Rotate the core by angle through the core rotation assembly 22; S30: Using the transfer mechanism 7, the wire harness on the wire harness fixing clamp 21 is moved to the wire harness clamp 33, and the terminal clamp 31 is displaced at the position where the terminal is clamped, so that the two terminals are moved to a set distance; S40: The wire harness on the wire harness clamping claw 33 is moved to the wire harness clamping assembly 52 by the transfer mechanism 7; S50: The housing clamping assembly 51 moves to the output port of the housing feeding mechanism 4 to clamp the housing, and the wire harness clamping assembly 52 moves closer to the housing clamping assembly 51 to assemble and connect the wire harness and the housing; S60: The wire harness on the wire harness clamping assembly 52 is transferred to the inspection mechanism 6 via the transfer mechanism 7, and the assembled wire harness is inspected for quality.

[0036] In the terminal shell insertion method described in the present invention, the wire harness feeding mechanism 1 first smoothly transfers and positions the double-core wire harness with crimped terminals onto the wire harness fixed clamp 21 to ensure that the two wire cores maintain a predetermined distance before entering the subsequent workstation. Subsequently, the wire core rotation assembly 22 is started to drive the wire cores to rotate synchronously or in reverse to a preset angle so that the orientation of the two terminals meets the requirements of the internal structure of the shell. After the rotation is completed, the first group of transfer mechanisms 7 accurately transports the wire harness from the fixed clamp to the terminal clamp 31 station; the terminal clamp 31 is then closed, and the distance between the two terminals is adjusted to a set value consistent with the shell cavity distance at one time through its own width positioning block 31b. After the distance is calibrated, the wire harness is again sent to the wire harness clamping assembly 52 by the transfer mechanism 7, and the square slot clamp locks the wire core, completely eliminating the risk of secondary displacement. At the same time, the shell clamping component 51 slides straight along the slider 51a to the exit of the vibration disk 41, and the clamping claw clamps a shell and returns; when the shell clamping component 51 and the harness clamping component 52 are aligned and close to each other, the two terminals are inserted into the shell at one time with the correct posture and spacing and realize self-locking of the buckle. Finally, the second group of transfer mechanisms 7 transports the assembled harness to the detection mechanism 6, and the visual, resistance or force-displacement sensors jointly detect the terminal buckle depth, insertion force and on-off status, and determine the qualified products to flow into the subsequent packaging process, and the unqualified products are automatically rejected. The entire process realizes closed-loop control of terminal angle adjustment, spacing calibration, shell assembly and quality verification without human intervention, which significantly improves the assembly efficiency and first-time pass rate of the intelligent harness.
