Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, and in particular to a shielding layer processing device based on the brush trajectory and an automatic assembly line for wire harness processing equipment. Background Technology

[0002] In wire harness production, shielding layer treatment is a crucial step. After the shielding layer is broken down, it needs to be twisted to facilitate subsequent processing. However, current shielding layer breaking devices often leave a small gap between the shielding layer and the wire core after breaking it down. This leads to issues such as the shielding layer's metal wires becoming mixed with some of the wire core, or some metal wires being missed when the shielding layer is twisted into a grounding wire. Furthermore, existing shielding layer combing devices often lack effective longitudinal combing capabilities, failing to ensure complete separation of the shielding layer from the wire core, resulting in incomplete twisting of the shielding layer or missing metal wires in subsequent processes.

[0006] According to the shielding layer processing device based on the upper brush trajectory of this utility model embodiment, the combing module includes a first driving member, the first driving member is connected to the longitudinal movement module, the combing brush is connected to the output end of the first driving member, and the first driving member can drive the combing brush to rotate.

[0007] According to the shielding layer processing device based on the upper brush trajectory of this utility model embodiment, the first driving component is a dual-output motor, and the two combing brushes are respectively connected to the two output ends of the first driving component. The first driving component can drive the two combing brushes to rotate simultaneously. or, The combing module includes a connecting shaft, with two combing brushes located at both ends of the connecting shaft. The output end of the first drive unit is connected to the connecting shaft through a first transmission mechanism, so that the first drive unit can drive the two combing brushes to rotate simultaneously.

[0008] According to the shielding layer processing device based on the upper brush trajectory of this utility model embodiment, the combing brush includes a body and a bristle assembly. The body is provided with a mounting groove, and two bristle assemblies are disposed in the mounting groove. The two bristle assemblies are arranged opposite to each other to form a combing channel through which the shielding layer can pass. And / or, The combing module includes a guide member disposed between the first clamping unit and the upper combing unit. The guide member has a guide groove for accommodating the shielding layer. The guide groove includes an arc-shaped connecting section and a straight connecting section. The arc-shaped connecting section is disposed on the same side as the first clamping unit, and the straight connecting section is disposed on the same side as the upper combing unit.

According to the shielding layer processing device based on the upper brush trajectory of this utility model embodiment, the longitudinal movement module includes a support frame, a second driving member, and a second transmission mechanism. The second driving member and the second transmission mechanism are mounted on the support frame. The second driving member is a motor. The combing module is connected to the second transmission mechanism. The output end of the second driving member is connected to the second transmission mechanism.

The cooperation between the upper combing unit and the translation unit achieves directional combing of the shielding layer in an arc shape upward, solving the problem of insufficient spacing between the shielding layer and the wire core after disassembly, and providing a sufficiently separated shielding layer for the subsequent twisting process. After the shielding layer is combed and separated from the wire core, the wire harness is conveyed to the twisting device. The twisting device clamps the free end of the shielding layer through the second clamping unit, and uses the third driving component to drive the second clamping unit to rotate, causing the combed shielding layer metal wires to be tightly wound into strands under the action of torsional force, preventing the loss of metal wires. The second clamping unit's fixing effect on the free end of the shielding layer, combined with the rotational drive of the third driving component, forms a controllable torsional torque, ensuring both the uniformity of the strands and preventing the metal wires from scattering due to lack of fixation.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of a utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Reference Figures 1 to 3 This utility model provides a shielding layer processing device, including a first clamping unit 300, an upper combing unit 100, and a translation unit 200. Wherein, as... Figure 1 As shown, the first clamping unit 300 is used to clamp and fix the wire harness, and the combing unit 100 is mounted on the translation unit 200. The translation unit 200 can drive the combing unit 100 to move along the working movement trajectory F2. The combing unit 100 is used to comb the shielding layer from bottom to top in the longitudinal direction, and the working movement trajectory F2 of the translation unit 200, together with the working movement trajectory F1 of the combing unit 100, forms a combing path F3 that is arc-shaped and upward towards the shielding layer.

[0024] Specifically, such as Figure 1As shown, the combing unit 100 includes a longitudinal movement module 110 and a combing module 120. The combing module 120 is mounted on the longitudinal movement module 110 and is mounted on the translation unit 200. The combing module 120 is provided with a combing brush 121. The combing brush 121 can contact the shielding layer of the wire harness. The longitudinal movement module 110 can drive the combing brush 121 to move in the longitudinal direction so that the combing brush 121 can comb the shielding layer in the longitudinal direction.

[0025] Understandably, after the wire harness is fixed by the first clamping unit 300, the longitudinal movement module 110 of the combing unit 100 drives the combing brush 121 to move vertically, so that the brush bristles contact the surface of the shielding layer. When the longitudinal movement module 110 drives the combing brush 121 to contact the shielding layer, the brush bristles apply a longitudinal force to the shielding layer, separating the metal wires. During the combing process, the translation unit 200 moves along the working movement trajectory F2, while the combing brush 121 moves along the working movement trajectory F1 under the drive of the longitudinal movement module 110. F1 and F2 combine to form the combing path F3. The directional movement of the brush bristles creates a stable gap between the shielding layer metal wires and the wire core, preventing mixing during subsequent processing.

[0026] Alternatively, in other embodiments of this application, the first clamping unit 300 is mounted on the translation unit 200. During the combing process, the translation unit 200 drives the first clamping unit 300 to move toward the upper combing unit 100, so that after the free end of the shielding layer 11 contacts the combing brush 121, the longitudinal moving module 110 drives the combing brush 121 to move in the longitudinal direction. At the same time, the combing brush 121 rotates during the upward movement. Furthermore, the translation unit 200 drives the first clamping unit 300 to continuously move toward the upper combing unit 100 to form a combing path F3 that is arc-shaped and upward toward the shielding layer.

[0027] Alternatively, in other embodiments of this application, both the first clamping unit 300 and the combing unit 100 are connected to the translation unit 200. During the combing process, one translation unit 200 drives the first clamping unit 300 to move toward the combing unit 100, while the other translation unit 200 drives the combing unit 100 to move toward the first clamping unit 300. This causes the free end of the shielding layer 11 to contact the combing brush 121, and the longitudinal movement module 110 drives the combing brush 121 to move in the longitudinal direction. At the same time, the combing brush 121 rotates during the upward movement, causing the free end of the shielding layer 11 to contact the combing brush 121, and the longitudinal movement module 110 drives the combing brush 121 to move in the longitudinal direction. Furthermore, the translation unit 200 and the combing unit 100 continuously approach each other under the drive of the translation unit 200 to form a combing path F3 that is arc-shaped and upward toward the shielding layer.

[0028] Furthermore, the translation unit 200 can also adjust the relative position of the first clamping unit 300 and the upper combing unit 100 according to the length of the wire harness to ensure that the combing brush 121 is always within the effective working range.

[0029] According to some embodiments of this application, the combing module 120 includes a first driving member 122, which is connected to the longitudinal movement module 110. The combing brush 121 is connected to the output end of the first driving member 122, and the first driving member 122 can drive the combing brush 121 to rotate.

[0030] Understandably, when the longitudinal movement module 110 moves the combing brush 121, the first driving component 122 synchronously drives the combing brush 121 to rotate around its own axis, causing the bristles to form a spiral motion trajectory during the longitudinal combing process. Each bristle generates a circumferential force when it contacts the shielding layer metal wire. The centrifugal force generated by the rotational motion causes the metal wires wrapped around the surface of the insulating layer to unfold outward, while the linear combing force generated by the longitudinal movement aligns the unfolded metal wires along a predetermined direction, effectively decomposing the mechanical entanglement force between the metal wires. Optionally, the first drive unit 122 is a dual-output motor, with two combing brushes 121 connected to the two output ends of the first drive unit 122 respectively. The first drive unit 122 can simultaneously drive the two combing brushes 121 to rotate. It can be understood that the first drive unit 122 is implemented as a servo motor or stepper motor with a dual-axis extension structure. By connecting the two output ends to the independent combing brushes 121 respectively, synchronous power output is achieved. When the motor starts, the two combing brushes 121 rotate at the same speed and direction, simultaneously combing the sections to be processed at both ends of the wire harness, effectively improving production efficiency.

[0031] Or, alternatively, such as Figure 1 As shown, the combing module 120 includes a connecting shaft, with two combing brushes 121 disposed at both ends of the connecting shaft. The output end of the first drive member 122 is connected to the connecting shaft via a first transmission mechanism, enabling the first drive member 122 to simultaneously drive the two combing brushes 121 to rotate. It can be understood that the output shaft of the first drive member 122 transmits power to the connecting shaft via gears or belts, causing the connecting shaft to drive the combing brushes 121 at both ends to rotate synchronously. This allows the two combing brushes 121 to simultaneously comb the sections to be processed at both ends of the wire harness, effectively improving production efficiency.

[0032] According to some embodiments of this application, such as Figure 2 As shown, the combing brush 121 includes a body 1211 and bristle assemblies 1212. The body 1211 is provided with a mounting groove, and two bristle assemblies 1212 are disposed in the mounting groove. The two bristle assemblies 1212 are arranged opposite to each other to form a combing channel 1213 through which the shielding layer can pass.

[0033] Understandably, the main body 1211 fixes the two bristle assemblies 1212 in relative positions via mounting slots. When the shielding layer enters the combing channel 1213, the bristle assemblies 1212 on both sides simultaneously apply contact force. During longitudinal movement, the shielding layer is confined within the channel, and the elastic deformation of the bristles on both sides ensures that the metal wires are evenly stressed, preventing loosening or omission caused by unilateral displacement. This application forms a bidirectional constraint channel through symmetrically arranged bristle assemblies 1212, ensuring that the shielding layer remains centered during movement, the metal wires are evenly combed, and they cannot escape laterally.

[0034] Or, in some other embodiments, such as Figure 3 As shown, the combing module 120 includes a guide 123, which is disposed between the first clamping unit 300 and the upper combing unit 100. The guide 123 is provided with a guide groove 1231 that can accommodate the shielding layer. The guide groove 1231 includes an arc-shaped connecting section 1232 and a straight connecting section 1233. The arc-shaped connecting section 1232 is disposed on the same side as the first clamping unit 300, and the straight connecting section 1233 is disposed on the same side as the upper combing unit 100. The combing brush 121 can move along the direction from the arc-shaped connecting section 1232 to the straight connecting section 1233 and comb the shielding layer.

[0035] Understandably, once the dispersed shielding layer enters the guide groove 1231, the drive unit starts and drives the combing brush 121 to perform unidirectional reciprocating motion along the extension direction of the groove. Specifically, the drive unit drives the combing brush 121 to comb the shielding layer from bottom to top, which not only enables the dispersed shielding layer fibers to form a uniform axial arrangement, but also further increases the spacing between the shielding layer and the wire core, so as to facilitate the subsequent twisting treatment of the shielding layer and the processing of the wire core.

[0036] The unidirectional movement path of the drive component ensures that the fibers are subjected to force in only one direction, avoiding secondary disturbances caused by bidirectional combing. After the combing brush 121 completes its single-pass movement, it automatically resets, awaiting the next work cycle. This application uses the combing module 120 to form a uniform axial arrangement of the dispersed shielding layer fibers, eliminating fiber cross-entanglement and providing a neat conductor bundle foundation for the subsequent twisting module.

[0037] Furthermore, the guide groove 1231 includes an arc-shaped connecting section 1232 and a straight connecting section 1233 connected in sequence, and the arc-shaped connecting section 1232 and the straight connecting section 1233 are arranged along the axial extension direction of the shielding layer.

[0038] Understandably, when the shielding layer enters the guide groove 1231, the metal wires of the shielding layer move along the arc-shaped connecting section 1232 to the straight connecting section 1233. The continuous connection between the arc-shaped and straight sections forms a path without abrupt changes, effectively eliminating the risk of the metal wires getting stuck at the turning points and the risk of the shielding layer metal wires breaking. Furthermore, the arc-shaped connecting section 1232 and the straight connecting section 1233 are arranged perpendicularly so that the shielding layer can form a larger separation distance from the core portion during combing, facilitating subsequent twisting of the shielding layer and processing of the core.

[0039] This application also provides an automated wire harness assembly line that can utilize the aforementioned shielding layer processing device. Specifically, such as... Figures 4 to 5 As shown, the automatic wire harness assembly line also includes a twisting device 400 disposed downstream of the shielding layer processing device. The twisting device 400 includes a twisting unit 410, which includes a third driving member 411 and a second clamping unit 412. The second clamping unit 412 is used to clamp and fix the free end of the shielding layer. The second clamping unit 412 is connected to the output end of the third driving member 411, and the third driving member 411 can drive the second clamping unit 412 to rotate to twist the shielding layer into strands.

[0040] Understandably, after the wire harness shielding layer is processed by the combing device, its metal wires are dispersed and spaced apart from the wire core. At this time, the free end of the shielding layer is clamped and fixed by the second clamping unit 412, and the third driving member 411 drives the second clamping unit 412 to rotate around the wire harness axis, so that the dispersed metal wires gradually wind into a tight strand structure under the action of torsional force. During the rotation process, the combing device and the twisting device 400 form a continuous operation process, and the conversion process of the shielding layer from dispersed to stranded is completed in a single device, avoiding the displacement of metal wires caused by manual transfer.

[0041] This application integrates combing and twisting processes, directly performing twisting while the shielding layer remains dispersed, eliminating interference from intermediate steps. Furthermore, standardized twisting operations are achieved through mechanical drive, ensuring consistent strand density. Moreover, by twisting the shielding layer wires into strands, the mixing and entanglement of the shielding layer wires with the core is effectively prevented, reducing the likelihood of the wires contacting the core due to gravity.

[0042] like Figure 4 As shown, the two twisted braiding units 410 are arranged in a horizontal direction. Optionally, the two twisted braiding units 410 can simultaneously twist the twisted shielding layers at both ends of the wire harness.

[0043] Alternatively, after the first twisting unit 410 completes the twisting of the initial segment, the second unit can perform supplementary twisting on the adjacent segment to cover any metal wires that may have been missed.

[0044] Furthermore, the twisting device 400 also includes a lifting unit 420, on which the twisting unit 410 is mounted. The lifting unit 420 can adjust the position of the twisting unit 410 in the vertical direction. Specifically, the lifting unit 420 and the twisting unit 410 are connected by a mounting plate or bracket. The driving component of the lifting unit 420 drives the mounting plate to move vertically through a transmission mechanism, thereby adjusting the height of the twisting unit 410. After the wire harness shielding layer is processed by the combing device, the lifting unit 420 moves the twisting unit 410 to the corresponding height according to the actual separation distance between the wire core and the shielding layer, so that the clamping mechanism can accurately grasp the free end of the shielding layer. During the twisting process, the lifting unit 420 can adjust its height in real time to ensure that a constant distance is maintained between the shielding layer and the wire core, avoiding entanglement or omission of the metal wires and the wire core.

[0045] In other embodiments of this application, the lifting unit 420 may employ a servo motor in conjunction with a ball screw structure, achieving precise position control through encoder feedback; or it may be driven by a cylinder, with the lifting stroke controlled by adjusting the air pressure. The twisting unit 410 may be mounted on the sliding platform of the lifting unit 420, with guide columns provided on both sides of the sliding platform to enhance stability.

[0046] This application achieves vertical position adjustment through the lifting unit 420, which can dynamically adjust the height of the twisting unit 410 according to the actual working conditions, ensuring that the shielding layer twisting operation is always in the optimal working position, so that the shielding layer twisting operation can adapt to the processing needs of different wire harness structures.

[0047] According to some embodiments of this application, such as Figure 4 and Figure 5 As shown, the wire core fixing unit 430 includes an upper clamping plate 431 and a lower clamping plate 432. The upper clamping plate 431 and the lower clamping plate 432 are provided with wire core limiting channels 433 at intervals in the vertical direction. The wire core limiting channels 433 are used to accommodate wire cores that have been separated from the shielded layer.

[0048] Understandably, after the shielding layer separates from the wire core, the wire core moves along the conveying direction F4 and is guided into the wire core limiting channel 433 through the guide port. The fixed distance formed by the upper clamping plate 431 and the lower clamping plate 432 constrains the wire core in the vertical direction. During the torsion of the shielding layer, the wire core is confined within the channel and cannot shift up or down, avoiding contact with the torsion shielding layer wires. In addition, the width of the wire core limiting channel 433 is adjustable, which can accommodate wire cores of different diameters, while avoiding damage to the wire core insulation layer due to excessive clamping.

[0049] Specifically, such as Figure 5 As shown, both the upper clamping plate 431 and the lower clamping plate 432 have folding sections at the ends near the shielding layer processing device, and the two folding sections are mirrored to form guide openings.

[0050] This application also provides an automatic wire harness assembly line (not shown in the figure) that utilizes the aforementioned shielding layer processing device.
