Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] The following description, in conjunction with the accompanying drawings, describes an integrated device, apparatus, multi-core wire harness machine, or multi-core wire harness assembly line for blowing and cutting wire harness fillers according to embodiments of the present invention.

[0031] Reference Figures 1 to 6 The present invention aims to provide an embodiment of a multi-core wire harness assembly line or a multi-core wire harness machine. The multi-core wire harness assembly line includes a wire harness supply device 110 and a wire harness filler blowing and cutting integrated device 120 or a wire harness filler blowing and cutting integrated equipment.

[0032] The wire harness supply device 110 is used to provide multi-core wire harnesses. The wire harness supply device 110 is mainly moved and conveyed by a linear guide rail, and provides one roll of multi-core wire harness each time it is conveyed.

[0033] Since a multi-core wire harness has two wire harness ends 100, the wire harness filler blowing and cutting integrated equipment has the ability to remove the filler from both wire harness ends 100. In terms of design, it is preferable to set up two filler removal mechanisms. The two filler removal mechanisms remove the filler from one wire harness end 100 respectively, thereby shortening the working cycle of the wire harness filler blowing and cutting integrated equipment and improving the wire harness production efficiency.

[0034] In terms of design, the wire harness supply device 110 and the wire harness filler blowing and cutting integrated device are relatively close to each other so that the wire harness filler blowing and cutting integrated device can partially remove the wire harness filler of the multi-core wire harness on the wire harness supply device 110.

[0035] Reference Figure 1 and Figure 5 In some specific embodiments of the present invention, the wire harness supply device 110 can be moved linearly and intermittently in one direction, which is beneficial to accurately control the moving position of the wire harness supply device 110 and avoid affecting the arrangement and operation of the multi-core wire harness assembly line.

[0036] In some specific embodiments of the present invention, the end of the wire harness 100 can protrude toward the side of the wire harness supply device 110, which facilitates the removal of filler by the wire harness filler blowing and cutting integrated equipment. At the same time, more space is reserved to reduce the arrangement pressure of the wire harness filler blowing and cutting integrated equipment.

[0037] In some specific embodiments of the present invention, the wire harness filler blowing and cutting integrated device can be moved in another perpendicular direction to meet the position requirements for removing the filler, while reducing the cooperation of the wire harness supply device 110 and simplifying the structure of the wire harness supply device 110.

[0038] Reference Figure 2The wire harness filler blowing and cutting integrated device includes a base 130 and a first movable frame 140 that moves along the base 130. The moving direction of the first movable frame 140 is preferably horizontal, and the moving direction of the first movable frame 140 is preferably the axial direction of the wire harness end 100, so that the integrated device can easily and quickly approach the wire harness end 100 and facilitate the removal of filler.

[0039] The first movable frame 140 can achieve precise positional movement by being driven by a motor and a ball screw, or by being driven by an electric cylinder, while the base 130 can be equipped with a limit sensor switch to control the movement range of the lower movable frame.

[0040] The first movable frame 140 is equipped with a second movable frame 150 and a third movable frame 160. The preferred direction of movement for the second movable frame 150 and the third movable frame 160 is vertical. The second movable frame 150 and the third movable frame 160 can share a common guide rail, reducing the number of parts and lowering manufacturing costs. Simultaneously, the second movable frame 150 and the third movable frame 160 can be driven by cylinders to achieve rapid lifting and lowering, facilitating the start and end of the filler removal process.

[0041] In this embodiment, the third movable frame 160 is provided with an air blowing mechanism 170, and the second movable frame 150 is provided with a clamping mechanism 180. The third movable frame 160 can be located above the second movable frame 150, so that the air blowing mechanism 170 is also located above the clamping mechanism 180. Accordingly, the air blowing mechanism 170 blows air downwards, so that the filler enters the clamping mechanism 180. On the one hand, the air blowing force and the gravity of the filler both cause the filler to bend downwards, which facilitates the separation of the filler from the wire harness core or wire core. On the other hand, it facilitates the deposition and collection of the filler generated by cutting.

[0042] Reference Figure 3 For the air blowing mechanism 170, the air blowing mechanism 170 is located in the radial direction of the wire harness end 100. The air blowing mechanism 170 blows air in the radial direction of the wire harness end 100 to cause the wire harness filler to deflect in the radial direction of the wire harness end 100.

[0043] In this embodiment, the air blowing mechanism 170 is located above the wire harness end 100, and the air blowing mechanism 170 blows air downward, causing the wire harness filler to bend downward.

[0044] In this embodiment, the blowing mechanism 170 has the lifting motion generated by the third moving frame 160, which allows the blowing mechanism 170 to move closer to and further away from the wire harness end 100, making it convenient to carry out and stop the blowing operation. At the same time, the blowing mechanism 170 can change the blowing intensity by moving closer to and further away from the wire harness end 100, and requires less adjustment of the blowing airflow size.

[0045] The air blowing mechanism 170 includes an air blowing bracket 200 slidably mounted on the third movable frame 160. The air blowing bracket 200 is movable in a first direction, and the third movable frame 160 is movable in a second direction. The first direction and the second direction are perpendicular to each other, and both the first direction and the second direction are radial directions of the wire harness end 100.

[0046] In this embodiment, the air blowing bracket 200 moves horizontally and is perpendicular to the moving direction of the first moving bracket 140. Therefore, when the air blowing bracket 200 moves horizontally, the air blowing mechanism 170 can sweep across the wire harness end 100, breaking up the filler in the wire harness end 100, so that the filler inside the wire harness end 100 can also be bent and separated, improving the degree of filler removal and reducing filler residue.

[0047] In some specific embodiments of the present invention, the air blowing mechanism 170 may include an air blowing pipe 190, which is disposed on the air blowing bracket 200. The air blowing pipe 190 has an air blowing port 210, which is connected to an external compressed air source, so that the air blowing port 210 generates an air blowing flow, which bends the filler.

[0048] In some specific embodiments of the present invention, a wire harness end 100 may be provided with a plurality of air inlets 210 to facilitate air blowing from different directions and improve the efficiency of bending or deflecting the filler.

[0049] In some specific embodiments of the present invention, a wire harness end 100 may be provided with three air blowing ports 210, the three air blowing ports 210 are arranged in a straight line, the arrangement direction of the three air blowing ports 210 is perpendicular to the axial direction of the wire harness end 100, and the air blowing airflow of the two outer air blowing ports 210 converges into the air blowing airflow of the middle air blowing port 210.

[0050] It is easy to understand that this embodiment provides three air inlets 210 to facilitate air blowing from directly above and two obliquely above the wire harness end 100, so that the filler can be fully dispersed and separated for cutting.

[0051] In some specific embodiments of the present invention, the third movable frame 160 may be provided with a first directional guide rail 220 and a first directional slider 230 connecting the first directional guide rail 220 and the air blowing bracket 200. The first directional guide rail 220 is located between the first directional slider 230 and the air blowing bracket 200. The third movable frame 160 is provided with a receiving groove 240 for accommodating the sliding of the first directional slider 230.

[0052] It is easy to understand that, by setting the first direction guide rail 220 and the first direction slider 230, this embodiment can meet the needs of the movement of the air blowing bracket 200. At the same time, since the first direction guide rail 220 is located between the first direction slider 230 and the air blowing bracket 200, it also makes the air blowing bracket 200 closer to the first direction guide rail 220, reducing torque, reducing the shaking of the air blowing bracket 200 and the fluctuation of the air blowing direction of the air blowing port 210, and avoiding affecting the air blowing quality.

[0053] The receiving groove 240 can not only accommodate the first direction slider 230, but also limit the range of motion of the first direction slider 230 to achieve stroke control, reduce the number of limit switches or limit switches, and reduce manufacturing costs.

[0054] In some specific embodiments of the present invention, a first direction slider 230 and an air blowing bracket 200 can be configured at each end of the first direction guide rail 220. At the same time, the two air blowing brackets 200 are connected by a connecting plate 250. Therefore, the two air blowing brackets 200 can be moved by a single power source, reducing the cost of setting up a power source.

[0055] In some specific embodiments of the present invention, an air blowing bracket 200 can be connected to a power component, which drives the air blowing bracket 200 to move horizontally. The power component can be a cylinder or the like, and the action is quick.

[0056] In this embodiment, Figure 1 , Figure 2 and Figure 3 The cylinder that drives the third movable frame 160 to rise and fall, and the cylinder that drives the air blowing bracket 200 to move horizontally are shown. The cylinder rod of the cylinder that drives the air blowing bracket 200 to move is equipped with an adjusting screw and an adjusting nut. The adjusting screw and adjusting nut can adjust the connection position between the air blowing bracket 200 and the cylinder rod, thereby changing the relative position between the air blowing port 210 and the wire harness end 100 during air blowing, which facilitates production debugging and obtains the best air blowing bending effect.

[0057] When the air blowing mechanism 170 completes its work, the filler is configured to extend radially along the end of the wire harness 100, or in other words, the filler is mostly perpendicular to the axial direction of the end of the wire harness 100.

[0058] Meanwhile, the configuration of the filler extending radially along the end 100 of the wire harness requires the cooperation of the clamping mechanism 180 to complete, which will be further discussed in the description of the clamping mechanism 180 in this application.

[0059] In this embodiment, the axial and radial directions are referenced to the axial and radial directions of the wire harness end 100, rather than the axial and radial directions of the wire harness body that is looped around it.

[0060] Reference Figure 4 , Figure 5 and Figure 6 For the clamping mechanism 180, the clamping mechanism 180 mainly includes a cutting component 260, a clamping component 270 and a pulling component 280.

[0061] In this embodiment, the cutting component 260, the clamping component 270, and the pulling component 280 are all disposed on the second movable frame 150, which facilitates the clamping mechanism 180 and the air blowing component to approach and move away from the wire harness end 100 synchronously or asynchronously, so as to meet the need for removing filler.

[0062] Reference Figure 4 For the cutting assembly 260, the cutting assembly 260 and the air blowing mechanism 170 are located on opposite sides of the wire harness end 100 in the radial direction. When the air blowing port 210 blows air onto the wire harness end 100, the cutting assembly 260 is used to abut and support the wire harness end 100 so that the wire harness filler is deviated from the wire harness end 100.

[0063] In other words, the cutting component 260 not only performs the function of cutting the filler, but also performs the functions of support and limit, so that the core wire or wire core at the end of the wire harness 100 and the unstripped part remain straight, and prevent the core wire or wire core from entering the cutting area 290 of the cutting component 260 and being cut off incorrectly.

[0064] More significantly, it eliminates component six and step seven in the existing technology, which helps simplify the equipment structure and improve production efficiency.

[0065] In some specific embodiments of the present invention, the cutting assembly 260 may have a limiting member 300 that abuts against and supports the wire harness end 100.

[0066] In some specific embodiments of the present invention, the limiting member 300 may have a cutting guide portion facing the wire harness filler, the cutting guide portion abutting against the wire harness filler to cut the wire harness filler, thereby enabling the limiting member 300 to have a dual function.

[0067] In some specific embodiments of the present invention, the cutting guide may include a V-shaped guide opening and / or a V-shaped inner cutting edge.

[0068] It is easy to understand that by setting a V-shaped guide or a V-shaped inner cutting edge, this embodiment can utilize the V-shaped shrinkage characteristic to make the filler relatively gathered, which makes it convenient for the clamping assembly 270 to clamp the filler.

[0069] The V-shaped inner cutting edge can not only bring the filler together, but also participate in the cutting and removal of the filler, so that the cutting or removal position is close to the root of the filler, resulting in less filler residue.

[0070] In some specific embodiments of the present invention, the opening direction of the V-shaped guide opening and the V-shaped inner cutting blade can be set along the axial direction of the wire harness end 100, and the opening direction of the V-shaped guide opening and the V-shaped inner cutting blade can be away from the direction of the wire harness body, the wire harness body being the part of the wire harness that has not had its sheath peeled off.

[0071] It is easy to understand that this embodiment improves the opening direction of the V-shaped guide opening and the V-shaped inner cutting blade, reserving a larger horizontal space for the fluffy end of the filler, and also makes it easier for the fluffy end of the filler to enter the V-shaped guide opening and the V-shaped inner cutting blade. That is, it facilitates the filler to enter the cutting area 290 and facilitates cutting and removal.

[0072] In some specific embodiments of the present invention, the cutting assembly 260 may include a cutting blade 320, and a channel may be formed between the cutting blade 320 and the cutting guide, the channel being the cutting area 290 or the guide hole, the channel accommodating the wire harness filler blown away by the air outlet 210, and the cutting blade 320 being able to approach the cutting guide to cut the wire harness filler.

[0073] In some specific embodiments of the present invention, the cutting blade 320 and the cutting guide can be arranged along the axial direction of the wire harness end 100, with the cutting blade 320 and the cutting guide relatively close to each other to cut the wire harness filler.

[0074] It is easy to understand that, since the filler is not twisted into a single strand in this embodiment, the filler will be distributed at multiple angles relative to the axial direction of the wire harness end 100. The cutting blade 320 is along the axial direction of the wire harness end 100, which is conducive to gradually cutting the filler, reducing the number of cotton threads cut at the same time, reducing cutting resistance, and making it easier to cut the filler. At the same time, less heating assistance is required, which is beneficial to environmental protection.

[0075] This application does not exclude the arrangement in which the cutting blade 320 and the cutting guide are relatively close to each other in the radial direction of the wire harness end 100, but the cutting effect and the influence of spatial arrangement need to be considered.

[0076] In some specific embodiments of the present invention, the cutting blade 320 can be positioned away from the wire harness body, which is the portion of the wire harness for which the sheath has not been peeled off.

[0077] It is readily understood that in this embodiment, the cutting blade 320 is arranged in... Figure 4 The location also avoids occupying the space between the wire harness supply device 110 and the wire harness filler blowing and cutting integrated device 120. At the same time, no other parts other than the limiting member 300 are needed for cutting, simplifying the structure.

[0078] Reference Figure 5For the clamping assembly 270, the clamping assembly 270 is used to clamp and fix the wire harness filler in the cutting area 290, so as to prevent the air blowing mechanism 170 from stopping or the air blowing force from being insufficient during cutting, and to prevent the wire harness filler from returning to its original position and affecting the cutting quality.

[0079] In some specific embodiments of the present invention, the clamping assembly 270 may include a first clamp 330 and a second clamp 340, which may be relatively close to or far apart from each other.

[0080] In this embodiment, the first clamp 330 and the second clamp 340 are relatively far apart and close together along the radial direction of the wire harness end 100, so that the first clamp 330 and the second clamp 340 are far away from the bending area of ​​the filler, so as to avoid affecting the bending or deflection effect of the filler.

[0081] In some specific embodiments of the present invention, the first clamp 330 may be provided with a first clamping portion 350, and the second clamp 340 may be provided with a second clamping portion 360. The first clamping portion 350 and the second clamping portion 360 abut against the filler and fix the filler. The first clamping portion 350 and the second clamping portion 360 extend along the axial direction of the wire harness end 100 to increase the clamping area of ​​the first clamp 330 and the second clamp 340, so as to facilitate clamping and fixing all bent fillers for cutting and removal.

[0082] In some specific embodiments of the present invention, the first clamp 330 and the second clamp 340 can be brought close to the cutting blade 320 and the limiting member 300, so that the clamping assembly 270 can clamp the root of the filler, so that the cutting assembly 260 can cooperate to cut the filler.

[0083] Reference Figure 5 and Figure 6 For the pull assembly 280, the pull assembly 280 is used to move the clamping assembly 270 away from the multi-core wire harness so that the filler is tightened.

[0084] In some specific embodiments of the present invention, the pulling assembly 280 may include a pulling power cylinder 380, and the clamping assembly 270 may include a clamping power cylinder 370. The cylinder bodies of the pulling power cylinder 380 and the clamping power cylinder 370 are arranged side by side. An mounting plate 390 is installed at the output end of the pulling power cylinder 380. The mounting plate 390 is connected to the cylinder body of the clamping power cylinder 370. A first clamp 330 and a second clamp 340 are provided at the output end of the clamping power cylinder 370.

[0085] It is easy to understand that by arranging the clamping power cylinder 370 and the pulling power cylinder 380 side by side in this embodiment, it is also beneficial to reduce the space occupied by the pulling component 280 and the clamping component 270, such as the height space in this embodiment, which is beneficial to reduce the height of the equipment.

[0086] The clamping power cylinder 370 and the pulling power cylinder 380 can work by pneumatic, hydraulic and electromagnetic drive. The same power configuration is preferred to reduce equipment cost and control difficulty.

[0087] In some specific embodiments of the present invention, the pulling power cylinder 380 and the clamping power rod can be arranged along the axial direction of the multi-core wire harness end 100, which also facilitates connection to the second movable frame 150 and simplifies installation.

[0088] In some specific embodiments of the present invention, the first clamp 330 and the second clamp 340 can be extended toward the side of the clamping power cylinder 370 away from the pulling power cylinder 380. This can make the effective length of the first clamp 330 and the second clamp 340 higher, and the external dimensions of the first clamp 330 and the second clamp 340 smaller, which is beneficial to reduce the space occupied.

[0089] In summary, by providing a multi-directionally movable air inlet 210 in the radial direction of the wire harness end 100, the present invention also facilitates changing the distance and direction of the air inlet 210 relative to the wire harness end 100, thereby separating the filler in the wire harness, causing the filler to deflect relative to the wire harness end 100, making it easier to remove the wire harness filler cleanly and reducing filler residue.

[0090] Meanwhile, the multi-directional movement of the air inlet 210 also facilitates the automated production of wire harnesses. For example, the wire harness is set on a transfer fixture, which is switched to various workstations along the production line. The wire harness filler blowing and cutting integrated device 120 can separate and remove the wire harness filler through its own movement. Reducing the adjustment of the transfer fixture helps to simplify the wire harness supply device 110 and the multi-core wire harness assembly line.

[0091] Meanwhile, the multi-directional movement of the air inlet 210 can overcome the characteristics of mixed distribution of wire harness filler in multi-core wire harnesses, making it particularly suitable for the production and manufacturing of multi-core wire harnesses.

[0092] A multi-core wire harness includes multiple wire cores and filler material between the multiple wire cores. The filler material is not completely distributed on the outside of the multi-core wire harness, which makes it difficult to fully disperse the multi-core wire harness by conventional air blowing methods. As a result, some filler material remains in its original state and cannot be separated by 100 degrees relative to the end of the wire harness, making it inconvenient to remove.

[0093] The present invention provides an air blowing mechanism 170 and a cutting component 260, which allows the air blowing mechanism 170 to blow the filler to the cutting area 290 of the cutting component 260, and also facilitates the cutting component 260 to cut the filler for removal.

[0094] The present invention provides a cutting component 260 that supports the end of the wire harness 100 and also makes the cutting position of the cutting component 260 as close as possible to the connection between the filler and the end of the wire harness 100, so that there is less filler residue after cutting.

[0095] By providing a clamping assembly 270, the present invention can fix the end of the filler away from the wire harness end 100, thus facilitating cutting by the cutting assembly 260.

[0096] The present invention provides a pulling component 280, which pulls the clamping component 270 away from the cutting area 290 and tightens the filler, so that the wire harness end 100 is in close contact with the cutting component 260, allowing the cutting component 260 to cut from the root of the filler, resulting in less filler residue and a cleaner wire harness end 100.

[0097] The present invention, by setting up an air blowing mechanism 170, a cutting component 260, a clamping component 270, and a pulling component 280, makes the blowing and cutting of wire harness filler mainly include four steps: blowing, clamping, pulling, and cutting. It eliminates at least steps six and seven in the prior art, reduces the number of filler removal steps, reduces the corresponding equipment structure, and makes the cutting or severing position closer to the root of the filler, resulting in less filler remaining.

[0098] The present invention provides a first clamping portion 350 and a second clamping portion 360 that extend along the axial direction of the multi-core wire harness end 100. This also provides the clamping assembly 270 with a clamping space extending along the axial direction of the multi-core wire harness end 100. Therefore, even when there are differences in the state of the filler extending along the radial direction of the multi-core wire harness end 100, the clamping assembly 270 can still clamp and fix the filler, which helps reduce omissions, facilitates cutting, and eliminates the need to twist the filler into a single strand before cutting. This saves on corresponding structures and steps, reduces costs, and improves the efficiency of filler removal.

[0099] At the same time, the filler is in a relatively dispersed state. When the cutting blade 320 moves the same distance, the number of fillers or cotton threads cut by the cutting blade 320 is smaller, requiring less heating assistance, which helps to reduce energy consumption, simplify the structure of the cutting blade 320, and also helps to reduce air pollution.

[0100] Therefore, referring to Figure 7 This application also provides an embodiment of a method for integrated blow-cutting of wire harness filler, which is applied to the aforementioned integrated blow-cutting equipment for wire harness filler.

[0101] The wire harness filler blow-cutting integrated method of this application mainly includes the following steps: 1. First, peel off the sheath at the end of the wire harness by 100 mm to form a stripped section.

[0102] 2. The wire harness supply device 110 fixes the portion of the wire harness near the stripping section and transfers the wire harness to the integrated device 120.

[0103] 3. The cutting component 260 supports the end 100 of the wire harness, and the air blowing mechanism 170 blows air onto the end 100 of the wire harness, so that the cotton thread is more perpendicular to the wire harness. That is, the air blowing separation step S1 is performed. The air blowing mechanism 170 blows air onto the end 100 of the wire harness, and the cutting component 260 supports the end 100 of the wire harness, so that the wire harness filler is deflected to the cutting area 290 of the cutting component 260.

[0104] 4. The clamping assembly 270 clamps the cotton thread, that is, the clamping step S2 is performed, and the clamping assembly 270 clamps the wire harness filler in the fixed cutting area 290.

[0105] 5. The pulling component 280 drives the clamping component 270 away from the air blowing mechanism 170, so that the cotton thread is taut. That is, the pulling step S3 is executed, and the pulling component 280 drives the clamping component 270 away from the cutting area 290 so that the wire harness filler is taut.

[0106] 6. The cutting component 260 cuts the cotton thread, that is, the cutting step S4 is performed, and the cutting component 260 cuts the taut thread bundle filler.
