[0002] In today's automotive wiring harness industry, the installation of waterproof plugs is a common and essential function in wiring harness processing equipment, and its process quality directly affects the sealing performance and service life of the wiring harness. Currently, the industry mainly relies on independent workstations for the processing of waterproof plugs for wiring harnesses, meaning that a single device completes the waterproof plug insertion operation for a single wiring harness.

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0052] like Figures 1 to 11 As shown, this embodiment of the invention provides a wire harness threading device for threading waterproof plugs 200 onto the wire harness to be processed, thereby improving the waterproofness and sealing of the wire harness. The wire harness threading device includes a waterproof plug feeding device, a wire harness handling device, and at least one set of threading devices 100. The waterproof plug feeding device is configured to convey the waterproof plug 200 through a threading tube 23 into the threading device 100. The wire harness handling device is configured to transport the wire harness to the threading position of the threading device 100 for threading the wire harness. For example, the wire harness threading device of this embodiment includes two sets of threading devices 100 arranged in parallel. Each set of threading devices 100 corresponds to one end of a U-shaped wire harness, thus enabling the device to simultaneously thread both ends of the same wire harness, improving threading efficiency. Of course, the two sets of threading devices 100 can also simultaneously thread two different wire harnesses, making the device compatible with single-head / double-head wire harness threading operations, further improving efficiency. Furthermore, the device can also be equipped with multiple sets of threading devices 100, allowing for simultaneous threading of multiple wire harnesses, making wire harness processing more efficient.

[0053] Each set of plug-in devices 100 includes a first mounting base 10, at least two sliding mechanisms 20, and a first drive assembly 30. Each sliding mechanism 20 is mounted on the first mounting base 10 and arranged sequentially along a first direction. Each sliding mechanism 20 includes a fixing block 21, a slider 22, a plug-in tube 23, and a plug-in connector 24. The fixing block 21 is fixed to the first mounting base 10, and the slider 22 is slidably connected to the fixing block 21 along a second direction intersecting the first direction. The slider 22 can move between the feeding position and the plug-in position along the second direction. The plug-in tube 23 is disposed through the first mounting base 10 and the fixing block 21 along a third direction. One end of the plug-in tube 23 is used to connect to the vibratory feeder through a pipeline, and one end of the plug-in tube 23 is used to connect to the plug-in connector 24. The plug-in connector 24 is disposed in the slider 22, and the plug-in connector 24 has a receiving cavity 242 adapted to the specified waterproof plug 200. The waterproof plug 200 has a central hole for the wire harness to pass through. When the slider 22 is in the feeding position, the plug connector 24 is opposite to the outlet position of the plug tube 23. At this time, the vibration of the vibratory feeder can blow the waterproof plug 200 into the plug connector 24 through the plug tube 23. When the slider 22 is in the plugging position, the external mechanism moves the wire harness to be plugged to a position opposite to the waterproof plug 200 in the plug connector 24, thus completing the preparation action for plugging the wire harness. Then, the external wire feeding mechanism drives the wire harness to move along a third direction and pass it into the central hole of the waterproof plug 200, completing the wire harness plugging action. During the wire harness plugging process, the rear end of the waterproof plug 200 always abuts against the fixing block 21, thereby preventing the waterproof plug 200 from moving backward under force and ensuring the reliability of the plugging process.

[0054] The first driving component 30 can selectively drive one of the sliders 22 to move along the second direction, or the first driving component 30 can simultaneously drive multiple sliders 22 to move along the second direction. In some embodiments, multiple sets of first driving components 30 can be provided, for example, the number of first driving components 30 is equal to the number of sliding mechanisms 20, so that each first driving component 30 drives each slider 22 in a one-to-one correspondence, which is easy to operate and convenient to control. In some embodiments, a single set of first driving components 30 can also be provided. By adjusting the position of the first driving component 30 along the Y direction or adjusting the position of the first mounting base 10 along the Y direction, the position of the first driving component 30 is relative to the desired sliding mechanism 20, so as to drive the corresponding slider 22 to move along the X direction. This has a simple structure and saves equipment costs.

[0055] This invention embodiment uses at least two sliding mechanisms 20, with the plug connectors 24 in different sliding mechanisms 20 being of different specifications. When a plugging operation is required for a wire harness of a certain specification, simply select the corresponding sliding mechanism 20, and the first driving component 30 pushes the corresponding slider 22 to the plugging position. Then, the wire harness can be inserted into the waterproof plug 200 of the corresponding specification, thus completing the plugging operation. The plugging device 100 of this invention embodiment can adapt to the plugging requirements of various specifications of wire harnesses and various specifications of waterproof plugs 200, realizing the insertion of wire harnesses into various waterproof plugs 200, effectively improving the plugging efficiency of wire harnesses, reducing production time, lowering equipment costs, and reducing equipment footprint. The wire harness plugging device of this invention embodiment has good compatibility and can be applied to the plugging operation of various specifications of wire harnesses and waterproof plugs 200. Moreover, its modular design makes maintenance and modification convenient, ensuring the processing quality of wire harness products.

[0056] In this embodiment, the first direction, the second direction, and the third direction intersect each other. Specifically, in this embodiment, the first direction is a vertical direction, the second direction is a horizontal direction, and the third direction is a horizontal direction perpendicular to the second direction. The third direction is specifically the extension direction of the wire harness. For ease of understanding, in the following content of this embodiment, the first direction is represented by the Y direction, the second direction by the X direction, and the third direction by the Z direction.

[0057] For example, in this embodiment, five sliding mechanisms 20 are arranged sequentially along the Y direction. The receiving cavity 242 of the plug connector 24 in the five sliding mechanisms 20 are of different sizes. This allows the plug-in device 100 to accommodate five different specifications of waterproof plugs 200, increasing the selectable types of waterproof plugs 200 during plug-in, further improving the compatibility of the plug-in device 100, and avoiding the problems of extended production time and low efficiency caused by frequent equipment changes.

[0058] Furthermore, the slider 22 of this embodiment is provided with a mounting groove, and the bolt connector 24 is detachably installed in the mounting groove of the slider 22. This makes it convenient and quick to disassemble and replace the bolt connector 24. Before bolting, a suitable bolt connector 24 can be installed in the slider 22 according to the diameter of the wire harness to be processed. This embodiment increases the reusability of the bolting device 100 and improves the versatility of the device.

[0059] Furthermore, the fixing block 21 in this embodiment is also provided with a wire-passing hole 211 extending in the Z direction. The diameter of the wire-passing hole 211 is larger than the outer diameter of the wire harness to be processed. This allows the front end of the wire harness to pass through the central hole of the waterproof plug 200 and extend into the wire-passing hole 211 during the plugging operation, thereby ensuring that the waterproof plug 200 can be completely connected to the wire harness. At the same time, the diameter of the wire-passing hole 211 is smaller than the outer diameter of the corresponding waterproof plug 200, so as to ensure that the rear end of the waterproof plug 200 always abuts against the fixing block 21 during the plugging process, and to prevent the waterproof plug 200 from being pushed back by external force, which would affect the plugging operation.

[0060] Optionally, each set of plug-in devices 100 further includes a guide mechanism to guide the insertion process of the wire harness, enabling the wire harness to be smoothly inserted into the waterproof plug 200. The guide mechanism specifically includes a first guide block 41, a second guide block 42, and a second drive assembly 43. The first guide block 41 and the second guide block 42 are located on the side of the sliding mechanism 20 along the Z direction near the wire harness. The first guide block 41 and the second guide block 42 are arranged opposite each other along the X direction. The first guide block 41 has a first semi-groove 411, and the second guide block 42 has a second semi-groove 421. The first semi-groove 411 and the second semi-groove 421, when joined together, form a conical inlet for the wire harness to pass through. When the slider 22 is in the plug-in position, this inlet is opposite to the center hole of the waterproof plug 200, allowing the wire harness to be quickly and accurately inserted into the waterproof plug 200 through this inlet. The second drive assembly 43 is fixed on the first mounting base 10. The second drive assembly 43 is used to drive the first guide block 41 and the second guide block 42 to move closer to each other or further away from each other in the X direction. The closing of the first guide block 41 and the second guide block 42 can form the above-mentioned inlet. The separation of the first guide block 41 and the second guide block 42 makes it convenient to take out the processed wire harness product after the bolt is inserted.

[0061] Furthermore, in this embodiment, each sliding mechanism 20 has a set of first guide blocks 41 and second guide blocks 42 respectively disposed on its outer side. For example, when there are five sliding mechanisms 20, there are also five sets of first guide blocks 41 and second guide blocks 42. The guiding mechanism in this embodiment also includes a first connecting block 44 and a second connecting block 45, with the first connecting block 44 fixedly connected to each first guide block 41 and the second connecting block 45 fixedly connected to each second guide block 42. The output end of the second driving component 43 in this embodiment is driveably connected to the first connecting block 44 and the second connecting block 45 respectively, to drive the first connecting block 44 and the second connecting block 45 to move closer or further apart, thereby simultaneously driving multiple first guide blocks 41 and multiple second guide blocks 42 on both sides to move synchronously. Specifically, the second driving component 43 in this embodiment is a pneumatic gripper, with its two output ends driveably connected to the first connecting block 44 and the second connecting block 45 respectively. The use of a pneumatic gripper in the second driving component 43 makes its structure compact, its gripping reliable, and its cost controllable.

[0062] In this embodiment, each set of bolt-threading devices 100 further includes a second mounting base 50 and a third drive assembly 60. A set of first drive assemblies 30 is provided and fixed to the second mounting base 50 by a bracket. The third drive assembly 60 is also fixedly mounted on the second mounting base 50. The output end of the third drive assembly 60 is connected to the first mounting base 10 and is used to drive the first mounting base 10 and each sliding mechanism 20 thereon to move synchronously along the Y direction. During the movement of the first mounting base 10 along the Y direction, one of the sliding mechanisms 20 can be positioned relative to the first drive assembly 30 as needed. Then, the third drive assembly 60 stops operating, and the first drive assembly 30 actuates to push the corresponding slider 22 from the loading position to the bolt-threading position. In this embodiment, the third drive assembly 60 drives the first mounting base 10 to move along the Y direction, so that only one set of first drive assemblies 30 is needed to achieve cooperation with multiple sliders 22, effectively reducing equipment costs.

[0063] Optionally, each sliding mechanism 20 further includes a support plate 25, a push rod 26, and an elastic reset member 27. The support plate 25 is fixed to the fixed block 21; the push rod 26 is movably inserted through the support plate 25 in the X direction, one end of the push rod 26 is fixedly connected to the slider 22, and the other end of the push rod 26 extends out of the support plate 25; the elastic reset member 27 is disposed between the push rod 26 and the support plate 25, and the elastic reset member 27 has a tendency to make the slider 22 move upward to the material position. In this embodiment, the first driving component 30 can be a cylinder. When the push rod of the cylinder extends, it can push the push rod 26 to move the slider 22 from the material position to the bolt position; and when the push rod of the cylinder retracts, the elastic reset member 27 can reset the slider 22 from the bolt position to the material position. In this embodiment, the corresponding slider 22 is pushed by a cylinder, which has a simple structure and reasonable design; the reset of the slider 22 is achieved by the elastic reset member 27, which simplifies the control process and ensures the rapid reset of the slider 22. Optionally, in this embodiment, the elastic reset member 27 is a compression spring, which is sleeved outside the top rod 26, and the two ends of the compression spring abut against the free end of the top rod 26 and the support plate 25.

[0064] In some embodiments, the threading device 100 further includes a third mounting base 70, a fourth drive assembly 80, and a base plate 90. The fourth drive assembly 80 is fixed to the third mounting base 70, which is fixed to the base plate 90. The output end of the fourth drive assembly 80 is connected to the second mounting base 50 and is used to drive the second mounting base 50 to move along the Z direction, thereby adjusting the position of the threading device 100 relative to the wire harness along the Z direction. That is, in this embodiment, the third drive assembly 60 provides power to the threading device 100 in the vertical direction, and the fourth drive assembly 80 provides power to the threading device 100 in the horizontal direction. The third drive assembly 60 and the fourth drive assembly 80 work together to adjust the position of the threading device 100. Specifically, the third drive assembly 60 and the fourth drive assembly 80 can be servo motors to improve the control accuracy and operational stability of the device.

[0065] Optionally, each sliding mechanism 20 is further provided with a waterproof plug detection component for detecting whether a waterproof plug 200 exists inside the plug-in connector 24. Specifically, the waterproof plug detection component includes a light emitter 28 and a light receiver 29. In an optional embodiment, the light emitter 28 and the light receiver 29 are respectively disposed at both ends of the sliding mechanism 20 along the X direction. The light emitter 28 is used to emit light to the light receiver 29. The waterproof plug 200 is located in the detection light path of the light emitter 28. When the light intensity received by the light receiver 29 is less than a set value or no light is received, it indicates that the light is blocked by the waterproof plug 200 inside the plug-in connector 24. It is determined that a waterproof plug 200 exists inside the plug-in connector 24 at this time, and the plug-in device 100 can proceed to the next plug-in operation. When the light intensity received by the light receiver 29 is greater than a certain set value, it indicates that there is no waterproof plug 200 inside the plug-in connector 24 at this time. At this time, it is necessary to stop the machine for inspection to determine whether a waterproof plug 200 needs to be added to the feeding mechanism or whether there are other faults. In another optional embodiment, the light emitter 28 and the light receiver 29 are disposed at the same end of the sliding mechanism 20 along the X direction. The light emitter 28 emits light towards the location of the waterproof plug 200, and the light receiver 29 determines whether the waterproof plug 200 exists in the plug connector 24 based on the intensity of the reflected light. The detection principle is a mature technology in the relevant field, and will not be described in detail in this embodiment. To facilitate the passage of the light path, the fixing block 21, the slider 22, and the plug connector 24 in this embodiment are respectively provided with clearance portions for the passage of the detection light path. Specifically, a first clearance hole 212 is provided on the side wall of one end of the fixing block 21, a second clearance hole 251 is provided on the support plate 25 at the other end of the fixing block 21, a first clearance notch 221 is provided on the slider 22, and a second clearance notch 241 is provided on the plug connector 24. The detection light path can pass through the above-mentioned clearance holes and clearance notches. This invention, by setting a waterproof plug detection component, avoids the plugging device 100 from running idle when there is no waterproof plug 200 in the plugging connector 24, thus ensuring the reliability of the wire harness plugging operation and reducing the defect rate of wire harness products.

[0066] The working process of the wire harness bolting device provided in this embodiment is as follows:

[0067] First, the position of the threading device 100 is adjusted by the third drive assembly 60 and the fourth drive assembly 80 so that the sliding mechanism 20 of a threading connector 24 with a specific specification is aligned with the first drive assembly 30. Then, the waterproof plug 200 with the material prepared is blown into the threading connector 24 by the threading tube 23 through the vibratory feeder. After that, the push rod 26 on the corresponding slider 22 is pushed by the first drive assembly 30, thereby moving the slider 22 to the threading position. Then, the first guide block 41 and the second guide block 42 are driven to close by the second drive assembly 43 to form an inlet for the wire harness to pass through. Then, the external mechanism moves the wire harness to be processed to the threading position and uses the inlet to thread the wire harness into the center hole of the waterproof plug 200, thereby completing the threading operation of the wire harness.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
