Description

TECHNICAL FIELD

[0001] The present application relates to an auxiliary assembly device for vehicle harness, belonging to the technical field of harness assembly production. BACKGROUND

[0002] Automobile harness is the network main body of automobile circuit, and there is no automobile circuit without harness. The harness refers to the assembly of connecting circuit formed by the compression of the contact terminal (connector) made of copper material and the wire cable, and the outer plastic compression insulation body or additional metal shell. The harness industry chain includes wire cable, connector, processing equipment, harness manufacturing and downstream application industry, and the harness is widely used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. The body harness connects the entire vehicle body.

[0003] In the forming process of vehicle harness connector, the following steps are generally required. First, the injection molding of the connector insulation support is performed, then the assembly of several harnesses and the connector insulation support is performed, the harness is required to correspond to the assembly channel of the connector insulation support, then the binding of the one side exposed end and the separation of the other side exposed end are performed, at this time, the main body is basically completed, and in the subsequent production, one end of the connector insulation support and the separation body is integrated with the injection molding of the connector, and the other end is assembled with the connector.

[0004] Among them, after the assembly and forming of the harness, the size of the two ends of the assembled harness is required to be high, and the insulation layer needs to be removed for assembly on one side, so when the harness is assembled and formed, the assembly precision and the insulation layer stripping are required, in addition, the harness also needs to be accurately positioned and bound to meet the limit during injection molding.

[0005] In the traditional harness assembly production process, manual harness threading is adopted, manual harness threading is difficult to guarantee the position accuracy and correspondence of harness threading, and the phenomena of missing installation, wrong installation and not threading in place often occur, resulting in low production efficiency and low product qualification rate. In view of this situation, at present, there are fully automatic equipment, which adopts the mode of cooperation of multiple harness supply and connector insulation support automatic supply to meet the automatic threading of harness, insulation layer stripping and automatic clamp operation of harness. However, the harness is a flexible body, and there are problems such as conveying deformation and alignment difficulty in the automatic threading process. Therefore, during the automatic operation process, shutdown failures often occur, and the automatic equipment often cannot run normally after being customized at a great cost, resulting in waste of production resources, and finally manual assembly is still adopted. In addition, during the operation of these automatic equipment, the main problems causing shutdown failure are as follows: firstly, when the harness is aligned and pushed, the rear end of the harness has the phenomena of unreliable cooperation and uncontrollable tension, resulting in the occurrence of harness loosening. If only one of the harnesses has a problem, the harnesses in the current process will be scrapped. Secondly, after the harness is assembled and formed, the free end of the harness has irregular phenomenon, so it is difficult to realize automatic separation of the liner body assembly, and manual assembly link is still needed. Finally, when the harness is supplied, multiple harness supply channels are adopted, which need to be separated at intervals, and at the same time, the relative position of the automatic threading station needs to be met. Therefore, the switching requirement of the harness supply alignment is very high, and the switching is one-to-one, which affects the threading efficiency, and the turnover alignment accuracy and equipment space are required to be high, so it is difficult to maintain effective process operation.

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the application more clear, the technical scheme in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0030] The application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, not to limit the application. In addition, it should be noted that only parts related to the application are shown in the drawings for convenience of description. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict.

[0031] The application provides an auxiliary assembly device for a vehicle wire harness, which is used for assembling and connecting a connector insulation support, a separate liner and a plurality of conductive wires, and the connector insulation support is provided with a plurality of wire channels.

[0032] As Figs. 1 to 4As shown, the auxiliary assembly equipment for the vehicle wire harness includes a base body 1, a support loading slot 2 is arranged on the base body 1, a wire harness feeding mechanism 3 and a wire harness traction sliding seat 4 are arranged on both sides of the support loading slot 2, the wire harness traction sliding seat 4 has linear displacement, and a separation liner guide groove 5 is arranged between the wire harness traction sliding seat 4 and the wire harness feeding mechanism 3.

[0033] The wire harness traction sliding seat 4 is provided with a traction matching channel 6 corresponding to the wire channel, and an inverted tooth ring taper 61 for locking the conductive wire is arranged in any traction matching channel 6.

[0034] Specific implementation process and principle description:

[0035] When the conductive wire and the connector insulating support are assembled, the connector insulating support is positioned and loaded in the support loading slot 2, and the wire harness feeding mechanism 3 feeds several conductive wires.

[0036] The conductive wire on the wire harness feeding mechanism 3 is manually pulled, so that the conductive wire enters the wire harness traction sliding seat after passing through the wire channel, and the traction matching channel 6 of the wire harness traction sliding seat is guided, and in the conductive wire plug-in state, the free end of the conductive wire passes through the inverted tooth ring taper 61 and abuts against the limiting baffle 40, which indicates that the conductive wire is matched with the wire harness traction sliding seat.

[0037] The wire harness traction sliding seat is linearly displaced and slid, so that the conductive wire is pulled as a whole, and after being pulled to a predetermined length, the distance forming is realized, and finally the conductive wire between the support loading slot 2 and the separation liner guide groove 5 is cut off, the separation liner is placed in the separation liner guide groove 5 after the cut-off part is combed by hand, and linear sliding is performed, so that the separation liner and the free end of the cut-off conductive wire are assembled and matched, and the high-efficiency auxiliary assembly forming requirement is met.

[0038] In one specific embodiment, the traction matching channel 6 is provided with a fastening matching body located on the side of the inverted tooth ring taper 61 away from the wire harness traction sliding seat, and the fastening matching body is a plurality of convex points 62 uniformly distributed in the circumference.

[0039] Specifically, the conductive wire has a certain toughness, and during the process of threading the conductive wire, the free end will be squeezed into the reverse tooth cone 61, and when pulling out, the insulation layer will be peeled off. The size is matched with the outer diameter of the conductive wire, and when disassembling after the assembly of the conductive wire is completed, the insulation layer needs to be peeled off. At this time, when pulling in the opposite direction, the reverse tooth cone 61 will peel off the insulation layer, and the peeling will generate traction on the peeled insulation layer. At this time, the protrusion 62 will generate a certain clamping force on the peeled insulation layer, so that it is left after peeling and will not be embedded in the reverse tooth cone 61, so that the insulation layer peeling is reliable and stable. At the same time, it meets the reliable and stable traction during the assembly of the wire harness. Of course, during disassembly, there are also cases where individual conductive wires fail to peel off successfully. At this time, manual detection and manual repair are required.

[0040] In one specific embodiment, a storage cabin 41 is provided between the limiting baffle 40 and the traction matching channel, and the limiting baffle is detachably matched with the wire harness traction sliding seat. Specifically, the limiting baffle is pivotally matched with the wire harness traction sliding seat, and a locking part is provided between the limiting baffle and the wire harness traction sliding seat.

[0041] Specifically, after the insulation layer is peeled off, there is a left pipe section, which will be pushed out during the second threading, so as to fall into the storage cabin 41. The opening and closing of the limiting baffle 40 meet the demand for removing waste materials and maintaining effective circulation.

[0042] In one specific embodiment, a linear sliding groove 7 for carrying the wire harness traction sliding seat is provided on the base body 1, and an adjustment limiting block 70 with adjustable displacement is provided in the linear sliding groove.

[0043] Specifically, the wire harness traction length has multiple specifications, and the adjustment limiting block 70 meets the adjustment demand of different specifications. In addition, the linear sliding groove is provided with a clamp groove 71, which is easy to lock after the wire harness traction, and the distance between the clamp groove 71 and the support loading groove 2 is accurate, which meets the positioning demand of subsequent injection molding.

[0044] In one specific embodiment, the support loading groove 2 is provided with a wire harness cutting mechanism 8 on the side facing the separation liner guide groove. The wire harness cutting mechanism includes two cutting knife seats 80 with relative displacement.

[0045] Specifically, after the wire harness is pulled into position, the relative displacement of the cutting knife seat 80 realizes the overall cutting of the wire harness, reduces the difficulty of manual pruning, and the fracture is smooth. During subsequent assembly of the separation liner, manual combing of the current cutting end can be performed.

[0046] In one embodiment, the separation liner guide groove 5 is provided with a detachable liner auxiliary guide sliding seat 50 which is detachably connected to the separation liner guide groove 5. The liner auxiliary guide sliding seat is provided with a separation liner loading groove on the side facing the bracket loading groove.

[0047] The liner auxiliary guide sliding seat 50 is detachably connected. After the wire harness is cut, the liner auxiliary guide sliding seat is assembled to meet the precise guide assembly and cooperation requirements of the separation liner.

[0048] Of course, in another preferred embodiment, the liner auxiliary guide sliding seat 50 can also have a through hole, that is, when the conductive wire is inserted, it passes through the liner auxiliary guide sliding seat 50 and the separation liner.

[0049] After the wire harness is pulled, the liner auxiliary guide sliding seat 50 is used to guide and assemble the separation liner, and then the sliding seat is reset. After the reset, the wire harness is cut. This embodiment is mainly used for small diameter conductive wires, and can realize front end traction force supplement. When it is used for thick conductive wires, it is generally cut and assembled. The front end is inserted through the multi-hole, which requires high technical requirements, and the segmented insertion is more smooth.

[0050] In one embodiment, the wire harness supply mechanism 3 includes a fixed supply plate 31 and a floating supply plate 32. The floating supply plate is arranged on the side of the fixed supply plate opposite the bracket loading groove. The floating supply plate has elastic displacement towards the fixed supply plate. The floating supply plate and the fixed supply plate are respectively provided with a plurality of wire supply channels.

[0051] Specifically, the traditional conductive wire is cut according to the length and then assembled. Its continuity is poor, and the recognition is insufficient, which can easily cause assembly errors or conductive wire scrap due to insertion errors.

[0052] In this case, the floating supply plate 32 and the fixed supply plate 31 are used in cooperation to make the floating supply plate 32 float and cooperate, so that there is a certain conductive wire retention between the two, which meets the tension of the conductive wire after the end of the floating supply plate 32 is pulled, and meets the regular and sequential continuous supply.

[0053] In one embodiment, the wire harness supply mechanism 3 includes a wire supply carrier 9 arranged on the base main body. The wire supply carrier is provided with a plurality of spool shafts.

[0054] It meets the requirements of different specifications, different colors and other conductive wires. It realizes continuous conductive wire supply. The fixed supply plate 31 has an identification mark, which can meet the supply and insertion identification requirements, so that the rear end of the conductive wire will not be misaligned, and the wire harness assembly is reliable, stable and smooth.

[0055] It can be found through the above description that the auxiliary assembling equipment for the wire harness for vehicles meets the auxiliary assembling requirements of the connector insulating support, the separation liner and the conductive wire, makes the assembling operation more smooth, and the product quality is reliable and stable. Different specifications of wire harnesses can be pulled and assembled to form, the separation liner assembling, the insulating layer peeling and the clamp online positioning assembling requirements are met, the assembling efficiency and quality are guaranteed. The equipment has the characteristics of low cost, smooth and efficient auxiliary operation, low scrap rate and the like, reduces the production equipment investment cost, and meets the batch online continuous assembling requirements.
