[0002] With the development of economy and the improvement of people's living standards, more and more families are buying cars, which has promoted the rapid development of the automobile industry. When producing cars, a large number of accessories are needed for assembly. Wiring harnesses are essential items in the process of automobile assembly. Without wiring harnesses, there would be no automobile circuits. Generally speaking, wiring harnesses are composed of multiple thin and long copper wires, some of which are as thin as hair. In order to prevent the wiring harness from being damaged, it is usually necessary to insert the wiring harness into a tube sleeve and fix the wiring harness in the tube sleeve to protect the wiring harness with the tube sleeve.

[0003] However, currently most of the wire harness threading is done by traditional manual operation, which requires the operator to hold the wire harness and pass it through the pipe sleeve by hand. Due to the large number of wire harnesses that need to be threaded through the pipe, it is inconvenient for people to pass the wire harnesses through the pipe sleeve together. Not only is the operation time long and the work efficiency low, but the operator is also easily fatigued over time, resulting in the wire harness not being accurately aligned with the hole, further reducing the efficiency of the pipe threading.

[0034] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0038] As mentioned in the background technology, a large number of accessories are needed for assembly during automobile production. Wiring harnesses are essential items in the automobile assembly process, such as Figure 1The single-strand wire harness 20 shown is composed of a plurality of thin and long copper soft wires, some of which are as thin as hair, for example, with a diameter of only 0.3 mm. In order to prevent the wire harness 20 from being damaged, the wire harness 20 is usually inserted into a tube sleeve 30 and fixed in the tube sleeve 30, so as to protect the wire harness 20 with the tube sleeve 30. However, most of the wire harnesses are currently threaded through the tube by traditional manual operations, requiring operators to hold the wire harness 20 and pass it through the tube sleeve 30. Since there are many soft wires that need to be threaded through the tube, it is inconvenient for people to pass the wire harness 20 through the tube sleeve 30, not only the operation time is long and the work efficiency is low, but also the operator is easily tired after a long time, resulting in the wire harness 20 not being accurately aligned with the hole, further reducing the efficiency of threading.

[0039] To this end, the present application provides a wire harness threading mechanism and a wire harness assembly device, wherein the wire harness assembly device includes a wire harness threading mechanism, which is used to thread a wire harness composed of multiple slender soft wires into a pipe sleeve, and then other mechanisms of the wire harness assembly device fix the wire harness in the pipe sleeve to complete the assembly of the wire harness.

[0040] The following uses the example of threading and assembling the wire harness used by the brush head of the motor in the automobile to illustrate the structure of the wire harness assembly device and the wire harness threading mechanism in the present application. It can be understood that in other embodiments, the wire harness assembly device and the wire harness threading mechanism in the present application are not limited to threading and assembling the wire harness used by the brush head of the motor in the automobile, but can also thread and assemble any wire harness, which is not limited here.

[0041] See also Figure 2 , Figure 2A schematic diagram of a wire harness assembly device 10 in an embodiment of the present application is shown. The wire harness assembly device 10 provided in an embodiment of the present application includes a machine 100, a wire harness feeding mechanism 200, a tube sleeve feeding mechanism 300, a wire harness threading mechanism 400, a feeding mechanism 600 and a screening mechanism 700, wherein the wire harness feeding mechanism 200, the tube sleeve feeding mechanism 300, the wire harness threading mechanism 400, the wire harness assembly mechanism 500, the feeding mechanism 600 and the screening mechanism 700 are arranged on the machine 100, and the wire harness feeding mechanism 200, the wire harness threading mechanism 400, the wire harness assembly mechanism 500, and the feeding mechanism 600 are arranged in sequence along a horizontally extending threading direction (i.e., the X direction indicated by the arrow in the figure), the tube sleeve feeding mechanism 300 is arranged next to the wire harness assembly mechanism 500, and the screening mechanism 700 is arranged next to the feeding mechanism 600. The wire harness feeding mechanism 200 is used to release the wire harness wound into a roll, and release the roll wire harness into a single strand wire harness, so as to feed the wire harness and tension the wire harness; the sleeve feeding mechanism 300 is used to provide the sleeve, and place the sleeve in the wire harness assembly mechanism 500; the wire harness threading mechanism 400 is used to insert the wire harness into the sleeve; the wire harness assembly mechanism 500 is used to squeeze the sleeve to fix the wire harness in the sleeve, and the wire harness assembly mechanism 500 is also used to cut the wire harness to cut off the excess wire harness exposed from the sleeve; the unloading mechanism 600 is used to unload the sleeve assembled with the wire harness; however, after assembly, the sleeve assembled with the wire harness will inevitably include good products and defective products, and the screening mechanism 700 is used to screen the good products and defective products after unloading, so as to distinguish the good products and defective products from each other and place them in different areas.

[0042] Specifically, the structures of various parts of the wire harness assembly device 10 are described below.

[0043] like Figure 2 As shown, the wire harness feeding mechanism 200 is located at the upstream of all the above mechanisms in the threading direction, and has a material roll release wheel 210 and a plurality of wire harness tension wheels 220 located downstream of the material roll release. Both the material roll release wheel 210 and the wire harness tension wheel 220 can rotate around their own central axis. Figure 2 In the embodiment shown in the figure, the material roll release wheel 210 is located above a plurality of wire harness tension wheels 220, which is used for sheathing the wire harness wound in a roll shape, so that when the material roll release wheel 210 rotates around its own central axis, the rolled wire harness can be released into a single wire harness to complete the loading of the wire harness. The plurality of wire harness tension wheels 220 are staggered up and down in sequence along the threading direction, and their function is to wind the released single wire harness to tension the wire harness and prevent the wire harness from being loose.

[0044] Figure 3 A schematic diagram of a wire harness threading mechanism 400 provided in an embodiment of the present application is shown, Figure 2As shown, the wire harness threading mechanism 400 is located downstream of the wire harness feeding mechanism 200 in the threading direction and upstream of the wire harness assembly mechanism 500. The wire harness threading mechanism 400 of this embodiment includes a first seat body 410, a second seat body 420, a guide tube 430 and a threading assembly 440, wherein a first driving cylinder 450 is provided on the first seat body 410, the second seat body 420 is connected to the first driving cylinder 450 and is slidably arranged on the first seat body 410, the guide tube 430 and the threading assembly 440 are sequentially arranged on the second seat body 420 along the threading direction, and the first driving cylinder 450 can be a pneumatic cylinder, an electric cylinder or a hydraulic cylinder, etc., which is used to drive the second seat body 420, the threading assembly 440 and the guide tube 430 to move together along the threading direction. The guide tube 430 is roughly conical, that is, the outer diameter of one end of the guide tube 430 is smaller than the inner diameter of the sleeve, and the inner diameter of the other end is larger than the inner diameter of the sleeve. It is used to be inserted into the sleeve before threading to provide guidance for the wire harness 20 when inserting the wire harness 20 to avoid the wire harness 20 from being misaligned with the hole; the threading assembly 440 is used to pass the wire harness 20 through the guide tube 430 and finally insert it into the sleeve.

[0045] Specifically, the threading assembly 440 includes a second drive cylinder 441 and a wire clamp 442. The wire clamp 442 is connected to the second drive cylinder 441 and can perform a clamping or releasing action to clamp the wire harness 20 or loosen the wire harness 20. The second drive cylinder 441 can also be a pneumatic cylinder, an electric cylinder or a hydraulic cylinder, etc., which is used to drive the wire clamp 442 to move relative to the guide tube 430 along the threading direction, so that the wire clamp 442 can clamp the wire harness 20 to pass through the guide tube 430 and insert the wire harness 20 into the pipe sleeve. Preferably, the second drive cylinder 441 is a servo cylinder. In addition to being able to clamp the wire harness 20 to pass through the guide tube 430 and insert the wire harness 20 into the pipe sleeve, the second drive cylinder 441 can also control the feed amount of the wire harness 20, thereby being able to control the depth of the wire harness 20 inserted into the pipe sleeve.

[0046] Preferably, a non-return clamp 460 is also provided on the first seat body 410. The non-return clamp 460 is similar to the wire pulling clamp 442 and can also perform a clamping or releasing action to clamp the wire harness 20 or loosen the wire harness 20, but the non-return clamp 460 cannot move along the threading direction. The function of the non-return clamp 460 is to clamp the wire harness 20 when the wire harness assembly mechanism 500 cuts off the excess wire harness 20 exposed outside the pipe sleeve, so as to tighten the wire harness 20, thereby preventing the wire harness 20 from bending, and further enabling the wire harness assembly mechanism 500 to cut off the wire harness 20 when cutting the excess wire harness 20, avoiding the situation of continuous cutting; and when the wire pulling clamp 442 clamps the wire harness 20, the non-return clamp 460 can loosen the wire harness 20, so that the wire harness 20 can move freely along the threading direction. After threading is completed, the wire pulling clamp 442 releases the wire harness 20, and the non-return clamp 460 clamps the wire harness 20 to prevent the wire harness 20 from retreating and escaping from the sleeve. At the same time, the second driving cylinder 441 drives the wire pulling clamp 442 to return to the initial position, and the first driving cylinder 450 drives the second seat body 420, the threading assembly 440 and the guide tube 430 to return to the initial position together.

[0047] In this way, when threading, the first driving cylinder 450 first drives the second seat body 420, the threading assembly 440 and the guide tube 430 to move together in the direction close to the pipe sleeve, so that the guide tube 430 is pre-inserted in the pipe sleeve, and then the non-return clamp 460 is in an open state. At this time, the second driving cylinder 441 drives the wire pulling clamp 442 to move relative to the guide tube 430 in the direction close to the pipe sleeve. Since the guide tube 430 is conical, the guide tube 430 can provide a guiding effect when threading, so that the wire pulling clamp 442 can clamp the wire harness 20 to more easily enter the guide tube 430 and pass through the guide tube 430, and then the wire harness 20 can be smoothly inserted into the pipe sleeve, thereby reducing manual operation errors and improving the success rate and efficiency of pipe threading of the wire harness 20 composed of multiple slender soft wires.

[0048] In a more preferred embodiment, the guide tube 430 is movably connected to the second seat body 420 by an elastic element 470 such as a spring, and the elastic element 470 is configured to be able to undergo restorable deformation when the guide tube 430 moves relative to the second seat body 420. In this way, when the guide tube 430 is inserted into the tube sleeve, due to the presence of the elastic element 470, the elastic element 470 can provide a certain buffer to avoid hard contact between the guide tube 430 and the tube sleeve, thereby avoiding damage to the guide tube 430 and the tube sleeve due to excessive contact force when they contact each other.

[0049] Furthermore, the wire harness threading mechanism 400 further includes a wire harness tidying component 480 and a wire harness guide block 490 disposed upstream of the threading component 440 along the threading direction. Figure 3As shown in the embodiment, there are two wire harness guide blocks 490, one of which is close to the non-return clamp 460, and the other is close to the wire harness feeding mechanism 200, and the wire harness regularization component 480 is arranged between the two wire harness guide blocks 490, and the wire harness guide block 490 is provided with guide holes (not marked in the figure) that pass through the opposite ends of itself in the threading direction, and the wire harness regularization component 480 includes a plurality of pairs of wire harness regularization wheels 481 arranged along the threading direction, and each pair of wire harness regularization wheels 481 includes two relatively spaced wire harness regularization wheels 481. Optionally, the two wire harness regularization wheels 481 in each pair of wire harness regularization wheels 481 can also be staggered in the vertical direction (i.e., the Z direction shown in the figure) or in the horizontal direction perpendicular to the threading direction (i.e., the Y direction shown in the figure) to further improve the regularization effect. In this way, before the wire harness 20 is inserted into the tube sleeve, it can pass through the guide hole and the gap formed by the two wire harness straightening wheels 481 in each pair of wire harness straightening wheels 481, so that the wire harness 20 can be guided and straightened, and the wire harness 20 can be further prevented from being scattered during transportation.

[0050] It is understandable that only the wire harness tidying component 480 or only the wire harness guide block 490 may be provided, and the number of the wire harness guide blocks 490 is not limited and is not limited here.

[0051] Please continue reading Figure 2 The tube sleeve feeding mechanism 300 is arranged beside the wire harness assembly mechanism 500. In terms of the structure of the tube sleeve feeding mechanism 300, the tube sleeve feeding mechanism 300 includes a feeding tray 310 and a first manipulator 320 arranged at intervals, wherein the feeding tray 310 can generate vibration to disperse the multiple tube sleeves put into the feeding tray 310, and the first manipulator 320 preferably has a flexible clamping claw, which is used to grab the tube sleeve into the wire harness assembly mechanism 500 after the tube sleeve is dispersed. Furthermore, a detection camera 330 is provided above the feeding tray 310, and the detection camera 330 is used to obtain the coordinates of the tube sleeve on the feeding tray 310, and to exchange information with the first manipulator 320, so that the first manipulator 320 can grab the tube sleeve in a set direction, so that the tube sleeve can be placed on the wire harness assembly mechanism 500 in a set posture.

[0052] In one embodiment, see Figure 4The wire harness assembly mechanism 500 has an assembly position 501 for placing a tube sleeve, and the wire harness is inserted into the tube sleeve at the assembly position 501 and fixed in the tube sleeve at the assembly position 501. As mentioned above, the wire harness assembly mechanism 500 fixes the wire harness in the tube sleeve by squeezing the tube sleeve, and can also cut the wire harness to cut off the excess wire harness exposed from the tube sleeve. Therefore, as a specific embodiment, the wire harness assembly mechanism 500 has a pressure cylinder 530, a pressure head 510 and a cutter 520 above the assembly position 501, wherein the cutter 520 is located on the side of the pressure head 510 close to the wire harness threading mechanism 400. The pressure head 510 is used to move downward to squeeze the tube sleeve under the drive of the pressure cylinder 530 to fix the wire harness inserted in the tube sleeve in the tube sleeve, and the cutter 520 is used to move downward to cut off the excess wire harness exposed from the tube sleeve under the drive of the pressure cylinder 530.

[0053] It can be understood that the pressing head 510 and the cutter 520 can move together or separately. When the pressing head 510 and the cutter 520 move together, the pressing head 510 and the cutter 520 are connected to the same pressing cylinder 530. When the pressing head 510 and the cutter 520 do not move together, the pressing head 510 and the cutter 520 are each connected to a pressing cylinder 530. There is no special limitation here.

[0054] Preferably, a cushion block 540 is further provided on the assembly position 501, and the cushion block 540 is used to support the wire harness exposed from the tube sleeve to prevent the cutter 520 from being unable to cut the wire harness exposed from the tube sleeve due to insufficient supporting force.

[0055] In this way, by simultaneously providing a pressing head 510 and a cutter 520 in the wiring harness assembly mechanism 500, the two processes of pressing and cutting can be completed in one mechanism, thereby optimizing the production process, improving the connectivity of the steps such as pipe threading, pressing, and cutting of excess wiring harnesses, making the production process smoother, and further reducing the input of manpower and materials, thereby reducing production costs.

[0056] See also Figure 5 , Figure 5 A structural schematic diagram of the unloading mechanism 600 in the wire harness assembly equipment 10 provided in this embodiment is shown. In this embodiment, the unloading mechanism 600 includes a transfer module 610 and a transfer platform 620 slidably arranged on the transfer module 610, wherein the transfer module 610 is a linear module in this embodiment, and has an input end 601 close to the wire harness assembly mechanism 500 and an output end 602 away from the wire harness assembly mechanism 500 at its opposite ends, and the transfer platform 620 is used to carry the pipe sleeve assembled with the wire harness, and under the drive of the transfer module 610, the transfer platform 620 can move back and forth between the input end 601 and the output end 602, so as to cyclically transfer the pipe sleeve assembled with the wire harness from the input end 601 to the output end 602.

[0057] As a further improvement, in an optional embodiment, a carrier 630 is further provided on the transfer platform 620, and a cavity matching the shape of the tube sleeve is opened on the carrier 630, so that the tube sleeve can be fixed to prevent the wire harness from passing through the tube sleeve and the tube sleeve assembled with the wire harness from moving from the input end 601 to the output end 602 at will, thereby avoiding affecting the product quality. Figure 6 As shown, in the above embodiment, the input end 601 of the transfer module 610 can be extended into the assembly position 501 of the wire harness assembly mechanism 500. When the first manipulator 320 of the tube sleeve loading mechanism 300 grabs the tube sleeve from the loading tray 310 to the cavity of the carrier 630, the transfer platform 620 can be located at the input end 601 and also at the assembly position 501, so that after the assembly is completed, the tube sleeve assembled with the wire harness can be directly transferred to the output end 602 by the transfer platform 620.

[0058] Please continue reading Figure 2 As can be seen from the figure, the screening mechanism 700 is arranged beside the output end 602 of the transfer module 610, and combined with Figure 7 As shown, the screening mechanism 700 includes a support 710, a good product detection sensor 720, a second manipulator 730 and a containing box 740. The good product detection sensor 720 and the second manipulator 730 are both arranged on the support 710. The containing box 740 is arranged below the second manipulator 730 and has a first cavity 741 and a second cavity 742. The good product detection sensor 720 is used to determine whether it is a good product or a bad product by taking a photo of the pipe sleeve assembled with the wire harness or other methods, for example, to determine whether the wire harness is inserted into the pipe sleeve or the quality of the insertion is qualified. If the wire harness is inserted into the pipe sleeve or the quality of the insertion is qualified, it is determined to be a good product, and if the wire harness is not inserted into the pipe sleeve or the quality of the insertion is unqualified, it is determined to be a bad product; the second manipulator 730 is used to move relative to the support 710 to place the good product in the first cavity 741, or place the bad product in the second cavity 742. Optionally, in a preferred embodiment, a movable cylinder 750 is provided at the bottom end of the bracket 710, and the accommodating box 740 is connected to the movable cylinder 750. Driven by the movable cylinder 750, the accommodating box 740 can move back and forth so that the first cavity 741 or the second cavity 742 can be respectively located at the output end 602 of the transfer module 610, thereby facilitating the second manipulator 730 to classify good products and defective products and place them in the first cavity 741 or the second cavity 742 respectively.

[0059] It should be noted that the structure of the wire harness assembly equipment 10 provided in the present application is not limited to the structure shown in the embodiment of the figure, but may also be other structures. For example, only a wire harness threading mechanism 400 and a wire harness assembly mechanism 500 may be provided, or, on the basis of the wire harness threading mechanism 400 and the wire harness assembly mechanism 500, only one, two or any multiple of the wire harness loading mechanism 200, the tube sleeve loading mechanism 300, the unloading mechanism 600 or the screening mechanism 700 may be provided. The specific arrangement may be based on actual needs and is not limited here. However, it is obvious that the simultaneous arrangement of the above-mentioned mechanisms enables the wire harness assembly equipment 10 to have the most complete functions and therefore has the highest degree of automation.

[0060] In addition, in order to improve production efficiency, such as Figure 2 and Figure 3 As shown, two wire harnesses 20 can also be fed, threaded and assembled at the same time. The specific implementation method is to set two material roll release wheels 210 on the wire harness feeding mechanism 200, respectively set two guide tubes 430, wire pulling clamps 442 and non-return clamps 460 in the wire harness threading mechanism 400, open two guide holes on the wire harness guide block 490, set two pressure heads 510 in the wire harness assembly mechanism 500, and open two cavities on the carrier 630, etc., so as to realize the simultaneous feeding of two wire harnesses 20 and two sleeves, respectively, and realize the threading of the two wire harnesses 20 into the sleeve, and also realize the unloading and screening of two sleeves assembled with the wire harnesses. Of course, more wire harnesses 20 can also be fed, threaded and assembled at the same time, which is not limited to the embodiments shown in the figure.

[0061] It can be seen that the wire harness assembly equipment provided by the present application realizes each step in the process of assembling the wire harness into the pipe sleeve, such as loading, pressing, cutting and unloading, in an automated manner, which greatly improves production efficiency and reduces the tediousness and time-consuming manual operation; and because of the use of an automated method for assembly, it can avoid possible errors in manual operation, thereby improving the quality stability of the product; further, since the need for manual operation is reduced, a large amount of labor costs can be saved, and since the automated method can achieve fast and precise operation, it can also reduce material waste, thereby reducing production costs; further, it realizes the close connection of various steps such as loading, pressing, cutting and unloading, thereby forming a complete production process, avoiding the problem of poor process caused by the independent performance of each step in the traditional method, thereby improving the fluency of production and overall efficiency.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
