Description

Technical Field

[0001] The present application relates to the field of wire harness processing, and particularly to a wire winding machine for wire harnesses. Background Art

[0002] With the popularization of electronic devices, wire harnesses for transmitting signals and delivering power to electronic devices are increasingly widely used. Moreover, in order to meet the usage requirements of different electronic devices, the structural types of wire harnesses are gradually becoming rich.

[0003] In the existing related technologies, one type of wire harness structure is a wire harness with a braided layer provided on its surface. The braided layer is formed by braiding sewing threads on the surface of the wire harness, and it tightly covers the surface of the wire harness. On the one hand, it meets the appearance requirements of different user groups, and on the other hand, it also makes the wire harness not easily scratched, thus effectively improving the service life of the wire harness.

[0004] Regarding the above related technologies, although the braided layer provided on the surface of the wire harness increases the surface structural strength of the wire harness, it also makes the wire harness not easy to bend and difficult to store. For example, a wire harness that is not easy to bend will be difficult to apply to a retractable data cable as described in the patent with the publication number CN 222365865 U. Summary of the Invention

[0005] In order to facilitate the production of easily bendable wire harnesses, the present application provides a wire winding machine for wire harnesses.

[0006] The wire winding machine for wire harnesses provided by the present application adopts the following technical solutions: A wire winding machine for wire harnesses includes a frame, a wire winding assembly, and a wire feeding assembly; The wire winding assembly includes a wire winding disc, a bobbin mounting rod, and a wire disc driving member; The wire winding disc is rotatably fitted to the frame. The wire winding disc is provided with a first wire harness through hole for the wire harness to pass through the wire winding disc along the wire winding and conveying direction; The bobbin mounting rod is used for mounting a bobbin of sewing thread. The bobbin mounting rod is mounted on the wire winding disc, and the mounting position of the bobbin mounting rod is eccentric with respect to the axis of the wire winding disc; The wire disc driving member is used for driving the wire winding disc to rotate; The wire feeding assembly is used for feeding the wire harness along the wire winding and conveying direction.

[0007] By adopting the above technical solution, the end of the sewing thread of the bobbin is fixed to the wire harness, and the wire is conveyed by the wire feeding assembly along the wire winding and conveying direction. When the wire moves along the wire winding and conveying direction, the winding disc rotates around its own axis, so that the bobbin revolves around the wire harness, and further makes the sewing thread wind around the surface of the wire harness circle by circle along the width direction of the wire harness, thereby forming a spiral surface layer (equivalent to a braided layer) on the surface of the wire harness.

[0008] When the wire harness is bent, the sewing thread spirally wound around the surface of the wire harness is prone to stack and approach each other or form gaps and move away from each other when bent, so that the wire harness is not easily deformed due to the too hard surface layer structure, thus facilitating the production of wire harnesses that are easy to bend.

[0009] Optionally, a plurality of bobbin mounting rods are provided, and the plurality of bobbin mounting rods are circumferentially distributed around the axis of the winding disc, and the mounting positions of the bobbin mounting rods can be adjusted in a direction approaching or departing from the axis of the winding disc.

[0010] By adopting the above technical solution, it is convenient to install bobbins with a large number of sewing threads through a plurality of bobbin mounting rods, and further, by changing the color or material of the sewing thread, etc., the surface layer of the wire harness can meet the needs of different consumers.

[0011] In addition, by providing bobbin mounting rods with adjustable mounting positions, it is convenient to change the mounting positions of the bobbins when fixing the sewing thread to the wire harness by traction, thereby providing sufficient working space for the staff and reducing the situation where the bobbins hinder the operation of the staff.

[0012] Optionally, the winding disc is provided with rod mounting holes for the bobbin mounting rods to pass through, and a plurality of rod mounting holes are provided; The plurality of rod mounting holes are divided into several groups, and the several groups of rod mounting holes are circumferentially distributed around the axis of the winding disc, and the rod mounting holes belonging to the same group are radially distributed along the winding disc.

[0013] By adopting the above technical solution, when it is necessary to change the position of the bobbin mounting rod, the bobbin mounting rods are respectively passed through different rod mounting holes, and then fixing parts such as screws and / or nuts can be used to quickly install the bobbin mounting rods in place, which is convenient and fast.

[0014] Optionally, the winding disc is provided with a first wire guiding disc, and the first wire guiding disc is slidably engaged with the winding disc along the wire winding and conveying direction; The first wire guiding disc is provided with a second wire harness through hole for the wire harness to pass through the first wire guiding disc along the wire winding and conveying direction; The first lead plate is provided with an outer lead member and an inner lead collecting member. The outer lead member and the inner lead collecting member are respectively provided with an outer lead hole and an inner lead collecting hole, and both the outer lead hole and the inner lead collecting hole are used for threading sewing threads. There are a plurality of the outer lead members, and the plurality of outer lead members are circumferentially distributed around the axis of the first lead plate. The outer lead members are farther from the axis of the first lead plate than the inner lead collecting member.

[0015] By adopting the above technical solution, when it is necessary to wind the sewing threads of multiple thread spools on the surface of the wire harness, the sewing threads of each thread spool are respectively threaded through the relatively close outer lead members, and then the multiple sewing threads are jointly threaded through the inner lead collecting hole, which is beneficial to reducing the occurrence of the situation that the multiple sewing threads are wound and not easily separated.

[0016] Optionally, the inner lead collecting member includes a first collecting block and a second collecting block. The first collecting block is installed on the winding disc, and the second collecting block is detachably installed on the first collecting block. The inner lead collecting hole is arranged in the second collecting block.

[0017] By adopting the above technical solution, it is convenient for the staff to remove the second collecting block from the winding disc during threading, and then there is enough working surface for the staff to thread the ends of single or multiple sewing threads through the inner lead collecting hole, reducing the occurrence of the situation that it is difficult to thread due to the obstruction of the thread spool.

[0018] Optionally, the winding machine for the wire harness further includes a threading member. The threading member includes a first threading block and a second threading block. The first threading block is used to install the threading member on the wire harness, and the second threading block is used to connect the sewing thread. The second threading block is detachably installed on the first threading block.

[0019] By adopting the above technical solution, the first threading block has a relatively large volume, which is convenient for the staff to lead the thread through the outer lead hole and the inner lead collecting hole, reducing the occurrence of the situation that it is difficult to lead the thread due to the overly soft end of the sewing thread. And after the threading is completed, the first threading block can be installed on the second threading block, thereby reducing the occurrence of the situation that the staff needs to tie the sewing thread to the wire harness or the sewing thread slips along the length direction of the wire harness.

[0020] Optionally, when the first threading block and the second threading block approach each other, the first threading block and the second threading block will attract each other.

[0021] By adopting the above technical solution, the mutually attracting first threading block and second threading block are beneficial to reducing the operation difficulty for the staff to install the first threading block on the second threading block.

[0022] Optionally, the winding disc is provided with a plurality of bobbin sliders, the plurality of bobbin sliders are circumferentially distributed around the axis of the winding disc, and the plurality of bobbin mounting rods are respectively mounted on the respective bobbin sliders; The bobbin slider is slidably engaged with the winding disc in the radial direction of the winding disc. The bobbin slider is detachably connected to the winding disc through a locking pin plate, and the locking pin plate is used to lock the sliding of the bobbin slider.

[0023] By adopting the above technical solution, when the position of the bobbin mounting rod needs to be changed, the locking pin plate is toggled so that the locking pin plate no longer locks the sliding of the bobbin slider, and then the bobbin slider is toggled, so that the bobbin slider can be quickly pushed away, thereby quickly providing enough working surface for the staff.

[0024] Optionally, the winding disc or the bobbin slider is provided with a pin attracting member. When the pin attracting member and the locking pin plate approach each other, the pin attracting member and the locking pin plate will attract each other.

[0025] By adopting the above technical solution, when the sliding of the bobbin slider needs to be locked, the locking pin plate is brought close to the pin attracting member, so that the pin attracting member and the locking pin plate attract each other, so that the locking pin plate is not easily loosened due to the rotation of the winding disc, which is beneficial to ensuring the stability of the bobbin slider during winding.

[0026] Optionally, the insertion and extraction direction of the locking pin plate is set at an angle with the radial direction of the winding disc, and when the winding disc rotates, the locking pin plate will move towards the direction close to the pin attracting member.

[0027] By adopting the above technical solution, the centrifugal force generated when the winding disc rotates makes the locking pin plate tend to approach the pin attracting member, so that the locking pin plate is not easily inclined to move away from the pin attracting member, which is beneficial to ensuring that the locking pin plate is not easily detached from the pin attracting member when the winding disc rotates. And when the staff forgets to lock the bobbin slider before starting the winding machine, the centrifugal force generated when the winding disc rotates will make the locking pin plate approach the pin attracting member, so that the locking pin plate locks the sliding of the bobbin slider.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. Fix the end of the sewing thread of the bobbin to the wire harness, and convey the wire through the wire feeding assembly along the wire winding conveying direction. When the wire moves along the wire winding conveying direction, the winding disc rotates around its own axis, so that the bobbin revolves around the wire harness, and then the sewing thread is wound around the surface of the wire harness circle by circle along the width direction of the wire harness, so as to form a spiral surface layer (equivalent to a braided layer) on the surface of the wire harness; When the wire harness is bent, the sewing thread spirally wound around the surface of the wire harness is likely to be stacked and close to each other or form gaps and move away from each other during bending. As a result, it is difficult for the wire harness to be deformed due to the too-hard surface layer structure, thus facilitating the production of a wire harness that is easy to bend. 2. Facilitate the installation of a large number of sewing thread bobbins through a number of bobbin mounting rods, and thus facilitate the compliance of the surface layer of the wire harness with the needs of different consumers by changing the color or material of the sewing thread, etc. In addition, by setting the bobbin mounting rod with an adjustable mounting position, it is convenient to change the mounting position of the bobbin when pulling the sewing thread to be fixed to the wire harness, thereby providing enough working space for the staff and reducing the situation where the bobbin hinders the operation of the staff.

Detailed implementation manners

[0043] The following further elaborates on the present application in conjunction with the attached Figures 1 - 13 drawings.

[0044] Embodiment 1: Embodiment 1 of the present application discloses a wire winding machine for a wire harness. Referring to Figure 1 , the wire winding machine for a wire harness includes a frame, a wire winding assembly 1, and a wire feeding assembly 2. The frame is arranged in a rectangular shape, and the wire winding assembly 1 and the wire feeding assembly 2 are both installed on the frame.

[0045] Referring to Figure 1 , there are two wire feeding assemblies 2, and the two wire feeding assemblies 2 are respectively arranged at the input end and the output end of the wire winding machine for a wire harness. The wire feeding assembly 2 includes a wire feeding frame body 21 and a plurality of wire feeding rollers 22. The wire feeding frame body 21 is installed on the frame through bolts, and two key grooves are formed through the wire feeding frame body 21 to facilitate fine adjustment of the wire feeding frame body 21 in the width direction of the frame. A plurality of wire feeding rollers 22 are all rotatably fitted on the wire feeding frame body 21, and one or more of the wire feeding rollers 22 are driven by a motor so that the wire harness 01 can move along the wire winding and conveying direction through the wire feeding roller 22 that is in pressing fit with the wire harness 01. In Embodiment 1 of the present application, the wire winding and conveying direction is arranged horizontally and along the length direction of the frame.

[0046] Referring to Figure 1, The winding assembly 1 is arranged between two wire feeding assemblies 2. The winding assembly 1 includes a winding disc 11, a bobbin mounting rod 12, and a winding disc driving member 13. The winding disc 11 is arranged in a disc shape and is rotationally fitted to the machine frame. The type of the winding disc driving member 13 is a motor, and the winding disc driving member 13 is fixedly installed on the machine frame. And the winding disc driving member 13 makes the winding disc 11 rotate around its own axis through a synchronous belt. The winding disc 11 is provided with a first wire harness perforation 101 penetrating along its own thickness direction. The first wire harness perforation 101 is circularly arranged and is coaxially arranged with the winding disc 11 to facilitate the wire harness 01 to pass through the winding disc 11 along the winding and conveying direction.

[0047] Refer to Figure 2 , The winding disc 11 is provided with a plurality of rod mounting holes 111. The plurality of rod mounting holes 111 are divided into eight groups. The eight groups of rod mounting holes 111 are circumferentially and uniformly distributed around the axis of the winding disc 11, and the rod mounting holes 111 belonging to the same group are radially distributed along the winding disc 11.

[0048] The bobbin mounting rod 12 is used to mount the bobbin of the sewing thread 02. Specifically, the bobbin is inserted and fitted to the bobbin mounting rod 12 and is limited by a nut, and the bobbin can rotate after being inserted and fitted to the bobbin mounting rod 12. There are four bobbin mounting rods 12. The four bobbin mounting rods 12 are circumferentially distributed around the axis of the winding disc 11, and the four bobbin mounting rods 12 are respectively arranged in one rod mounting hole 111 of four groups of rod mounting holes 111. The bobbin mounting rod 12 is adapted to the rod mounting hole 111, and the bobbin mounting rod 12 can be directly thread-fitted to the rod mounting hole 111 through threads, or can be installed by being inserted into the rod mounting hole 111 and then cooperating with a nut against the back surface of the winding plate for tightening. When the position of the bobbin mounting rod 12 needs to be changed, just replace the rod mounting hole 111 where the bobbin mounting rod 12 is installed correspondingly. The structure is simple and reliable, which is beneficial to reducing the situation that the bobbin mounting rod 12 affects the operation of the staff.

[0049] Refer to Figure 1 , Four adjusting slide rods 112 are fixedly installed on the winding disc 11. The four adjusting slide rods 112 are circumferentially and uniformly distributed around the axis of the winding disc 11, and the four adjusting slide rods 112 are all arranged along the winding and conveying direction, that is, the length direction of the machine frame. The winding disc 11 is provided with a first wire guiding disc 3 and a second wire guiding disc 4 through the four adjusting slide rods 112. Among them, the first wire guiding disc 3 is closer to the winding disc 11 than the second wire guiding disc 4.

[0050] Refer to Figure 3, the first lead plate 3 is circularly arranged. The first lead plate 3 is simultaneously and slidably engaged with four adjustment slide rods 112 through four first slide holes with damping to ensure the stability of the first winding disc 11. The first lead plate 3 is provided with a second wire harness perforation 301 through which the wire harness 01 is adapted to pass through the first lead plate 3 along the winding and conveying direction, and the second wire harness perforation 301 is coaxially arranged with the first lead plate 3.

[0051] The first lead plate 3 is provided with an outer lead member 31 and an inner lead gathering member. Among them, there are four outer lead members 31 and one inner lead gathering member. The four outer lead members 31 are circumferentially and uniformly distributed around the axis of the first lead plate 3, and the four outer lead members 31 are farther from the axis of the first lead plate 3 than the inner lead gathering member.

[0052] The outer lead member 31 is arranged close to the bobbin of the sewing thread 02, and the outer lead member 31 is provided with an outer lead hole 302 through which the sewing thread 02 wound around the bobbin can pass through the outer lead hole 302 along a shorter path, thereby reducing the occurrence of the situation where the sewing thread 02 is deflected, wound and knotted.

[0053] Refer to Figure 3 and Figure 4 , the inner lead gathering member includes a first lead gathering block 32 and a second lead gathering block 33. The first lead gathering block 32 is fixedly installed on the first lead plate 3, and the second lead gathering block 33 is installed on the first lead gathering block 32 through bolts (not shown in the figure) to facilitate the disassembly of the second lead gathering block 33. The second lead gathering block 33 is provided with an inner lead gathering hole 303 through which the multi-strand sewing thread 02 can pass through the inner lead gathering hole 303 after passing through the respective outer lead holes 302, so as to facilitate ensuring that the sewing thread 02 is wound more tightly on the surface of the wire harness 01 and reducing the situation where the surface of the wire harness 01 is exposed outside the sewing thread 02.

[0054] Refer to Figure 3 , the second lead plate 4 is circularly arranged. The second lead plate 4 is simultaneously and slidably engaged with four adjustment slide rods 112 through four second slide holes with damping so that the second lead plate 4 is not easily changed in its own position under the action of an external force after sliding. The diameter of the second lead plate 4 is greater than or equal to the diameter of the first lead plate 3 so that the sewing thread 02 passing through the first lead plate 3 is not easily caught and wound by the outside during rotation.

[0055] The second lead wire reel 4 is provided with a third wire harness perforation 401 through which the wire harness 01 is configured to pass through the second lead wire reel 4 along the wire winding and conveying direction. The third wire harness perforation 401 is coaxially arranged with the second lead wire reel 4, the second wire harness perforation 301, and the first wire harness perforation 101, so as to facilitate adjusting the angle between the sewing thread 02 and the wire harness 01 through the inner wall of the third wire harness perforation 401, and further changing the angle when the sewing thread 02 winds around the surface of the wire harness 01. For example, bringing the second lead wire plate closer to the first lead wire reel 3 will make the angle between the sewing thread 02 and the wire harness 01 closer to a right angle, and will increase the angle between the sewing thread 02 wound around the surface of the wire harness 01 and the axis of the wire harness 01, thereby facilitating the sewing thread 02 to quickly wind around the surface of the wire harness 01.

[0056] The implementation principle of Embodiment 1 of the present application for a wire winding machine for a wire harness is as follows: Thread the sewing thread 02 of the required bobbin through the outer ring lead hole 302, then thread each sewing thread 02 through the inner ring wire gathering hole 303 of the second wire gathering block 33, and then install the second wire gathering block 33 on the first wire gathering block 32 through bolts.

[0057] After the second wire gathering block 33 is installed, tie and fix the sewing thread 02 threaded through the inner ring wire gathering hole 303 to the surface of the wire harness 01, and then bring the second lead wire reel 4 closer to the first lead wire reel 3 so that the sewing thread 02 provided on the first lead wire reel 3 is enclosed.

[0058] Subsequently, start the wire reel driving member 13 and the wire feeding assembly 2, so that the winding reel 11 starts to rotate, and the wire harness 01 moves along the wire winding and conveying direction, and then the sewing thread 02 gradually starts to wind around the surface of the wire harness 01.

[0059] Refer to Figure 5 , when the sewing thread 02 is firmly wound around the surface of the wire harness 01, increase the rotation speed of the winding reel 11 to the production speed, so that the sewing thread 02 quickly winds around the surface of the wire harness 01, thereby forming an easily bendable spiral surface layer on the surface of the wire harness 01.

[0060] Embodiment 2: Embodiment 2 of the present application discloses a wire winding machine for a wire harness, which is different from Embodiment 1 in that: Difference 1: The setting of the winding reel 11 is different.

[0061] Refer to Figure 6 and Figure 7, the winding reel 11 is provided with four reel chutes 113, and the four reel chutes 113 are circumferentially and evenly distributed around the axis of the winding reel 11, and the four reel chutes 113 all extend along the axis direction of the winding reel 11. A bobbin slider 114 is slidably engaged with the reel chute 113, and the bobbin slider 114 is used for fixedly installing the bobbin mounting rod 12. The winding reel 11 is also provided with eight locking grooves 102. Every two of the eight locking grooves 102 are divided into a group, and the two locking grooves 102 in each group are respectively located on both sides of the reel chute 113, and the locking grooves 102 are arranged close to the outer edge of the winding reel 11.

[0062] The bobbin slider 114 is slidably engaged with a locking pin plate 115 with damping, and the locking pin plate 115 is arranged close to the outer edge of the winding reel 11, so that it is convenient for the staff to toggle the locking pin plate 115 without being blocked by the bobbin. The sliding direction of the locking pin plate 115 is arranged at an angle with the radial direction of the winding reel 11, that is, the sliding direction of the locking pin plate 115 and the radial direction of the winding reel 11 do not face the same straight line direction, so that the locking pin plate 115 has a movement tendency to approach the locking groove 102 when the winding reel 11 rotates.

[0063] In addition, in some other embodiments, it is also possible to choose to arrange the locking pin plate 115 on the winding reel 11 and arrange the locking groove 102 on the bobbin slider 114.

[0064] An insert attracting member 116 is arranged inside the locking groove 102, and the insert attracting member 116 and the locking pin plate 115 will attract each other through magnetic force or negative pressure. Specifically, in Embodiment 2 of the present application, the locking pin plate 115 has ferromagnetism, and the type of the insert attracting member 116 is a magnet, so that when the insert attracting member 116 and the locking pin plate 115 approach each other, the insert attracting member 116 and the locking pin plate 115 are attracted to approach each other, so that the locking pin plate 115 is more likely to be tightly attached and inserted into the locking groove 102 when the winding reel 11 rotates.

[0065] Difference 2: The settings of the inner ring wire collecting member and the second lead wire reel 4 are different.

[0066] Refer to Figure 8 , the first wire collecting block 32 is provided with two fixing protrusions 321, and the second wire collecting block 33 is provided with two fixing grooves corresponding to the fixing protrusions 321, so that when the second wire collecting block 33 is installed on the first wire collecting block 32, by inserting the fixing protrusions 321 into the fixing grooves, the second wire collecting block 33 is temporarily fixed to the first wire collecting block 32, thus facilitating the staff to screw the bolts.

[0067] Refer to Figure 8 and Figure 9, the winding disc 11 is provided with an outer ring jack 402 and an inner ring jack 403, and both the outer ring jack 402 and the inner ring jack 403 are provided in a penetrating manner. The outer ring jack 402 is used for the outer ring lead piece 31 to be inserted and fitted with the second lead disc 4, and the inner ring jack 403 is used for the inner ring wire collecting piece to be inserted and fitted with the second lead disc 4. When the second lead disc 4 approaches the first lead disc 3, the top parts of the outer ring lead piece 31 and the inner ring wire collecting piece are respectively inserted and fitted with the outer ring jack 402 and the inner ring jack 403, so as to ensure the installation stability of the first lead disc 3 and the second lead disc 4, and make the sewing thread 02 be stably arranged between the first lead disc 3 and the second lead disc 4, reducing the occurrence of the sewing thread 02 being interfered by the outside world.

[0068] Difference 3: The winding machine for wire harnesses further includes a wire threading member 5.

[0069] Refer to Figure 10 , the wire threading member 5 includes a first wire threading block 51, a second wire threading block 52 and a third wire threading block 53.

[0070] The first wire threading block 51 includes a first wire threading sub-block and a second wire threading sub-block, and both the first wire threading sub-block and the second wire threading sub-block have magnetism, so as to clamp and fix the wire harness 01 through the mutually attracting first wire threading sub-block and second wire threading sub-block, thereby installing the first wire threading block 51 on the wire harness 01.

[0071] The second wire threading block 52 includes a third wire threading sub-block and a fourth wire threading sub-block, and both the third wire threading sub-block and the fourth wire threading sub-block have magnetism, so as to clamp and fix the thread end of the sewing thread 02 through the mutually attracting third wire threading sub-block and fourth wire threading sub-block, thereby installing the second wire threading block 52 on the sewing thread 02, and facilitating the detachably adsorbing and installing the second wire threading block 52 on the first wire threading block 51.

[0072] The third wire threading block 53 includes a fifth wire threading sub-block and a sixth wire threading sub-block, and both the fifth wire threading sub-block and the sixth wire threading sub-block have magnetism, so as to reduce the assembly difficulty of the fifth wire threading sub-block and the sixth wire threading sub-block through the mutually attracting fifth wire threading sub-block and sixth wire threading sub-block, and facilitate the detachably adsorbing and installing the second wire threading block 52 on the first wire threading block 51.

[0073] Refer to Figure 11 and Figure 12 , a wire collecting cavity 501 is formed between the third wire threading block 53 and the first wire threading block 51. The wire collecting cavity 501 is provided with a plurality of cavity openings, so as to collect the multi-strand sewing threads 02 fixed to each second wire threading block 52 through the wire collecting cavity 501 and extend them out from one of the cavity openings of the wire collecting cavity 501, making the multi-strand sewing threads 02 tightly wound on the surface of the wire harness 01, reducing the occurrence of the exposed surface of the wire harness 01.

[0074] Difference 4: The wire feeding assembly 2 is differently arranged.

[0075] Refer to Figure 6 and Figure 11 , the wire feeding assembly 2 located at the output end of the wire winding machine for the wire harness is provided with two adjusting sliders 211. The two adjusting sliders 211 are slidably engaged with the wire feeding frame 21 in the vertical direction, and the wire feeding rollers 22 are rotatably engaged with the adjusting sliders 211, so that the wire feeding rollers 22 respectively installed on the adjusting sliders 211 approach or move away from each other.
