Description

Technical Field

[0001] The present invention relates to the technical field of cable twisting, and in particular to a twisting device for producing electronic cables and a working method thereof. Background Art

[0002] During the twisting process, the strands are prone to breakage. Because the twisting process places high demands on the mechanical properties and stability of the wire harness, the wire harness is susceptible to breakage at the strands when subjected to force, torsion, or friction. Furthermore, the number of wires that break is often uncertain; it could be just one wire or multiple wires simultaneously, further complicating the problem.

[0003] It is worth noting that if the initial breakage is not discovered and intervention measures are not taken in time, the broken harness may have a negative impact on other surrounding cables and even interfere with the normal twisting process. For example, the broken harness may become entangled with other normal cables during the twisting process, or uneven force may cause other cables to be pulled and worn, causing more breakage. This chain reaction will not only reduce the overall quality and performance of the harness, but may also cause the damage to spread further, increasing repair costs and production time. Therefore, timely intervention in the harness during the twisting process is crucial to prevent the initial breakage problem from evolving into a more serious quality incident.

[0022] The control information is sent to the electric push rod to control the electric push rod to start pushing out.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The present invention controls the activation of the dust-cleaning shielding component by setting up the dust-cleaning shielding component, so that impurities on the wire harness are adsorbed and collected to keep the wire harness clean, thereby preventing the finished product from being affected by impurities. If one or more wire harnesses are broken during the twisting process, the dust-cleaning shielding component can adsorb the broken wire harness so that the broken wire harness can enter the interior of the dust-cleaning shielding component, thereby facilitating the positioning of the broken wire harness to prevent the broken wire harness from damaging other wire harnesses when it breaks off. In addition, the debris generated when the wire harness breaks can also be collected by the dust-cleaning shielding component, thereby preventing the debris generated when the wire harness breaks from adhering to the wire harness and affecting the twisting.

[0025] (2) The present invention sets the guide plate and the baffle. On the one hand, the increase in the bottom distance changes the contact area and angle of the airflow and increases the suction force. Therefore, when the cable breaks, its weight and adhesion to the surrounding environment may hinder it from naturally entering the storage box, while the greater suction force can overcome these resistances, which is conducive to promoting the broken cable to be sucked into the storage box more smoothly. On the other hand, when the distance above the guide plate is reduced, it means that the movement space of the wire harness after entering the storage box is subject to certain restrictions. By limiting the disordered movement of the wire harness in the box due to its own forces (such as inertia, centrifugal force, etc.). Then, when the wire harness enters the storage box, due to the reduction in the distance above the guide plate, the movement trajectory and direction of the wire harness are guided and constrained, making it more difficult for it to swing or rotate significantly under its own force, thereby reducing the possibility of being thrown out, which is conducive to protecting the wire harness and preventing it from being damaged again due to violent movement in the storage box, and facilitating subsequent processing or collection.

[0026] (3) The present invention arranges a roller cylinder and a clamping plate, arranges a roller cylinder, and arranges the roller cylinder to move in one direction through a one-way bearing, so that after the two roller cylinders clamp the cable, the broken wire bundle is adsorbed and contacts the roller cylinder, and the wire bundle may move toward the connection port under the action of friction. However, if the broken cable wants to move to the outside of the absorption box, it cannot rotate due to the restriction of the one-way bearing of the roller cylinder, so that the wire bundle is restricted by static friction, which is beneficial to prevent the wire bundle from being thrown out after being adsorbed.

[0035] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0036] Application Scenario: During the twisting process of wire harnesses, the twist joint is a high-risk area for wire harness breakage. Because the twisting process places high demands on the mechanical properties and stability of the wire harness, wire harnesses are prone to breakage at the twist joint when subjected to force, torsion, or friction. Furthermore, the number of wires that break is often uncertain; it may be just one wire or multiple wires simultaneously, which complicates the problem.

[0037] It is worth noting that if the initial breakage is not discovered and intervention measures are not taken in time, the broken harness may have a negative impact on other surrounding cables and even interfere with the normal twisting process. For example, the broken harness may become entangled with other normal cables during the twisting process, or uneven force may cause other cables to be pulled and worn, causing more breakage. This chain reaction will not only reduce the overall quality and performance of the harness, but may also cause the damage to spread further, increasing repair costs and production time. Therefore, timely intervention in the harness during the twisting process is crucial to prevent the initial breakage problem from evolving into a more serious quality incident.

[0038] like Figures 1 to 7 The wire stranding equipment shown in the figure for producing electronic cables comprises a frame 1 for supporting, a distribution tray 2 for guiding the wire harness for stranding is provided on the frame 1, and there are multiple distribution trays 2;

[0039] A transmission shaft 3 for transmitting power is connected to the center of the outer surface of one side of the distribution plate 2;

[0040] The surface of the distribution plate 2 is provided with a plurality of grooves for the wiring harness to pass through in a circumferential array, and the outer surface of the other side of the distribution plate 2 is provided with guide wheels 4 equal to the number of grooves;

[0041] The frame 1 is provided with a twisting element 5 for twisting a plurality of wire harnesses delivered from the distribution tray 2;

[0042] The frame 1 is provided with a winding mechanism for collecting the finished stranded wire;

[0043] The frame 1 is provided with a dust cleaning and shielding component for cleaning dust on the wire harnesses before twisting the multiple wire harnesses and for shielding the fractures generated during the twisting process of the wire harnesses. The dust cleaning and shielding component is arranged on the side of the twisting member 5 close to the distribution plate 2.

[0044] Specifically, the wire harnesses to be twisted are respectively passed through the wire grooves on the distribution plate 2 and guided by the guide wheel 4. The transmission shaft 3 is externally connected to a power source for driving the distribution plate 2 to rotate, and the external power source is also provided with existing components such as a wire reel for unwinding the wire harness. This is a prior art and will not be elaborated on here.

[0045] Furthermore, the wire harness on the distribution plate 2 is twisted by the twisting member 5. After the twisting is completed, the twisted cable is connected to the reeling mechanism. The reeling mechanism is a component for reeling and collecting the twisted cables. It is an existing mature technology and will not be elaborated on here, thereby completing the twisting of the wire harness.

[0046] Among them, the twisting element 5 is an existing technology, which is often used in the twisting of cables and is a mature technology and will not be elaborated on in detail.

[0047] When twisting multiple wires together to make a cable, the wires are easily contaminated with dust, dirt, and other impurities during movement. Although each wire is cleaned before twisting, it is inevitable that some impurities will temporarily stick to it during the actual operation, or the wires may break due to various factors during the twisting process.

[0048] If dust and other dirt are stuck on the wire harness, the performance and quality of the cable after twisting will be affected; and if the wire harness breaks and is not discovered and handled in time, the wire harness may come into contact with other unbroken wire harnesses during the breaking process, and may also cause damage to other wire harnesses. Therefore, by setting a dust cleaning and shielding component before twisting multiple wire harnesses, and then controlling the start of the dust cleaning and shielding component, the impurities on the wire harness are adsorbed and collected to keep the wire harness clean, which is beneficial to prevent the finished product from being affected by impurities. If one or more wire harnesses break during the twisting process, the dust cleaning and shielding component can adsorb the broken wire harnesses so that the broken wire harnesses can enter the inside of the dust cleaning and shielding component, which is beneficial to limit the broken wire harnesses to prevent the broken wire harnesses from damaging other wire harnesses when they break, and the debris generated when the wire harness breaks can also be collected by the dust cleaning and shielding component, which is beneficial to prevent the debris generated when the wire harness breaks from adhering to the wire harness and affecting the twisting.

[0049] As a technical optimization solution of the present invention: the dust cleaning and shielding assembly includes a fixed plate 6 installed on the frame 1, the top of the fixed plate 6 is connected to a protective shell 7, the outer wall of the protective shell 7 is provided with a through opening 8 for all wiring harnesses to pass through, the interior of the protective shell 7 is provided with an adsorption assembly and a storage box 9, the storage box 9 is provided with a connecting port 10, and the connecting port 10 is connected to the adsorption assembly.

[0050] Specifically, the adsorption component is controlled to start working, and the adsorption component discharges the air inside the storage box 9 to the outside through the connection port 10. After the air inside the storage box 9 is discharged, a negative pressure space is formed at the opening of the storage box 9. On the one hand, the negative pressure space formed at the storage box 9 can collect impurities adhered to the wire harness before it is twisted, so as to prevent the impurities from affecting the subsequent twisting effect. On the other hand, after the wire harness breaks, it can enter the interior of the storage box 9 under the action of negative pressure, which is beneficial to prevent the wire harness from causing damage to other wire harnesses after it breaks, and in this process, the debris generated when it breaks can also be adsorbed by the storage box 9, which is beneficial to prevent the debris generated when it breaks from flying onto other wire harnesses, thereby affecting the subsequent twisting.

[0051] As a technical optimization solution of the present invention: the adsorption component includes a fan 11, the fan 11 is installed inside the protective shell 7, and the air inlet end of the fan 11 is fixedly connected to the connecting port 10 through the air duct 12.

[0052] Specifically, the fan 11 is controlled to start, and the fan 11 discharges the air inside the storage box 9 to the outside through the air duct 12 and the connecting port 10, thereby facilitating the formation of a negative pressure space in the storage box 9.

[0053] As a technical optimization solution of the present invention: a slide 13 is connected to the hinged part 5, an adjustable screw 14 is provided on the slide 13, a connecting rod 15 is threadedly connected to the outer wall of the adjustable screw 14, the connecting rod 15 is slidably connected to the inside of the slide 13, the end of the connecting rod 15 is fixedly connected to an inclined guide plate 16, a groove 17 is provided on the guide plate 16, a stop block 18 is fixedly connected to the inside of the groove 17, and a connecting assembly is provided between the guide plate 16 and the slide 13.

[0054] It should be understood that the position of the connecting rod 15 is adjusted by the adjustable screw 14, so that the guide plate 16 is adjusted to a suitable position. The two guide plates 16 are arranged to form an inverted eight-shaped shape, which is conducive to the collection of impurities by the guide plate 16. After the impurities enter the groove 17 on the guide plate 16, they will slide down under the action of gravity and be blocked and collected by the block 18. On the one hand, it is conducive to the subsequent unified collection and cleaning of impurities. On the other hand, it is conducive to intercepting and blocking some impurities to prevent impurities from clogging the connecting port 10.

[0055] As a technical optimization solution of the present invention: the connecting component includes a slide plate 19, which is slidably connected to the slide 13, and a spring 20 is installed between the slide plate 19 and the guide plate 16, and the spring 20 is sleeved on the outer wall of the connecting rod 15.

[0056] Furthermore, the position of the guide plate 16 is limited by the spring 20, so that the guide plate 16 can swing stably within a certain range, which is beneficial to prevent it from deviating from the normal working position due to excessive swinging amplitude, ensuring that the guide plate 16 can always be in the effective working range, providing a stable basis for impurity collection, and the fan 11 makes the guide plate 16 swing, which can change the movement trajectory and distribution state of the impurities through the shaking, breaking the position of the impurities in the airflow, which is beneficial to make the impurities easier to contact with the block 18, achieving better interception and collection effects, thereby helping to avoid the impurities passing directly with the airflow and reducing the collection amount.

[0057] As a technical optimization solution of the present invention: the inner wall of the protective shell 7 is connected to a rectangular frame 21, a rectangular groove 22 is provided on the rectangular frame 21, an L-shaped slide 23 is slidably connected to the inside of the rectangular groove 22, a baffle 24 is provided on the side wall of the L-shaped slide 23, the baffle 24 is located inside the rectangular groove 22, a shift rod 25 is fixedly connected to the L-shaped slide 23, the shift rod 25 is in contact with the guide plate 16, the end of the L-shaped slide 23 is fixedly connected to an elastic telescopic rod 26, the fixed part of the elastic telescopic rod 26 is fixedly connected to the rectangular frame 21 through the fixed plate 6, and an electric push rod 27 for pushing the guide plate 16 to deflect is fixedly installed inside the protective shell 7 through a connecting plate.

[0058] It should be understood that by starting and controlling the electric push rod 27, the electric push rod 27 pushes the guide plate 16 to deflect, and the guide plate 16 gradually tends to a vertical state. In the initial state, the two guide plates 16 partially block the connection port 10. By tilting the guide plate 16, the suction force can be effectively controlled, because when the guide plate 16 is in a tilted state, its contact area and angle with the airflow change, thereby changing the flow rate and flow of the airflow through the connection port 10, reducing the suction force. This is beneficial to avoid excessive suction from having an adverse effect on the twisting process, thereby protecting the normally twisted wire harness. If the suction force is too large, it may generate excessive pulling force or adsorption force on the twisted wire harness, resulting in uneven tension of the wire harness, inconsistent twisting pitch, or damage to the wire. Therefore, after reducing the suction force by the tilted guide plate 16, it can be ensured that the wire harness maintains stable tension and normal operating state during the twisting process, thereby ensuring the twisting quality;

[0059] When the electric push rod 27 is activated, the wire harness breaks. When the guide plate 16 deflects, it simultaneously drives the lever 25 to move, which in turn drives the L-shaped slide 23 to move, which in turn drives the retaining rod 24 to move. During this process, the two retaining rods 24 move closer together, thereby clamping the wire harness and preventing it from being thrown out again after entering the storage box 9. As the guide plate 16 deflects, the bottom distance between the two guide plates 16 increases, while the top distance decreases. On the one hand, the increased bottom distance changes the contact area and angle of the airflow, increasing the suction force. Therefore, when a cable breaks, its weight and adhesion to the surrounding environment may hinder its natural entry into the storage box 9. The greater suction force can overcome these obstacles, facilitating smoother suction of the broken cable into the storage box 9. On the other hand, the reduced top distance of the guide plate 16 means that the movement space of the wire harness after entering the storage box 9 is somewhat restricted. By limiting the disordered movement of the wire harness in the box due to its own forces such as inertia and centrifugal force, when the wire harness enters the storage box 9, the distance above the guide plate 16 is reduced, and the movement trajectory and direction of the wire harness are guided and constrained, making it more difficult for it to swing or rotate significantly under its own force, thereby reducing the possibility of being thrown out, which is beneficial to protecting the wire harness and preventing it from being damaged again due to violent movement in the storage box 9, and facilitating subsequent processing or collection.

[0060] As a technical optimization solution of the present invention: the outer wall of the blocking rod 24 is rotatably connected to the rolling cylinder 28 through a one-way bearing, and the outer wall of the rolling cylinder 28 is fixedly connected to a clamping plate 29.

[0061] It should be understood that by providing a roller cylinder 28 and setting the roller cylinder 28 to move in one direction through a one-way bearing, after the two roller cylinders 28 clamp the cable, the broken wire harness is adsorbed and contacts the roller cylinder 28, and the friction force may cause the wire harness to move toward the connection port 10. However, if the broken cable wants to move to the outside of the absorption box, it cannot rotate due to the restriction of the one-way bearing of the roller cylinder 28, thereby restricting the wire harness through static friction, which is beneficial to prevent the wire harness from being adsorbed and then thrown out.

[0062] As a technical optimization solution of the present invention: the internal rotation of the connecting port 10 is connected to the fan blade 30 which is forced to rotate when the fan 11 is working. The top center of the fan blade 30 is fixedly connected to the rotating cylinder 31, and the end of the rotating cylinder 31 is fixedly connected to the conical cylinder 32.

[0063] It should be understood that in order to further fix the adsorbed wire harness, the fan 11 will cause the blades 30 to rotate under the action of wind when it is working. The blades 30 will drive the rotating cylinder 31 to rotate during the rotation, and the rotation of the rotating cylinder 31 will drive the conical cylinder 32 to rotate, which is conducive to adsorbing the wire harness into the interior of the conical cylinder 32, thereby facilitating the adsorption and collection of impurities on the end of the wire harness, and after entering the interior of the conical cylinder 32, the adsorption force generated by the connection between the conical cylinder 32 and the connecting port 10 is used to adsorb and fix the cable to prevent it from swinging.

[0064] As a technical optimization solution of the present invention: a plurality of articulated plates 33 are fixedly connected to the interior of the conical cylinder 32, all of the articulated plates 33 are fixedly connected to the interior of the conical cylinder 32 in a circular array, and a plurality of tooth grooves 34 are opened on the articulated plates 33.

[0065] It should be understood that after the broken wiring harness enters the interior of the conical cylinder 32, the provided tooth grooves 34 can further restrict the wiring harness, thereby further reducing the large-scale swinging or rotation of the wiring harness under its own force, preventing secondary damage to the wiring harness, and avoiding the difficulty of subsequent repairs.

[0066] A working method of a stranding device for producing electronic cables, the working method comprising the following steps:

[0067] Acquiring first data information, where the first data at least includes tension information;

[0068] Generate control information based on the first data information, the first control information is used to control the start of the electric push rod 27;

[0069] The control information is sent to the electric push rod 27 to control the electric push rod 27 to start pushing out.

[0070] It should be understood that tension information can be obtained through the tension sensor, and changes in the tension information can indicate wire breakage. Control information is generated based on the tension information and sent to the electric push rod to control the electric push rod to start pushing out, thereby completing the work of subsequent components.

[0071] Working principle of the present invention:

[0072] The wire harnesses to be twisted are respectively passed through the wire grooves on the distribution plate 2 and guided by the guide wheel 4. The transmission shaft 3 is externally connected to a power source for driving the distribution plate 2 to rotate, and the external power source is also provided with existing components such as a wire reel for unwinding the wire harness. This is a prior art and will not be elaborated on here.

[0073] Furthermore, the wire harness on the distribution plate 2 is twisted by the twisting member 5. After the twisting is completed, the twisted cable is connected to the reeling mechanism. The reeling mechanism is a component for reeling and collecting the twisted cables. It is an existing mature technology and will not be elaborated on here, thereby completing the twisting of the wire harness.

[0074] Among them, the twisting element 5 is an existing technology, which is often used in the twisting of cables and is a mature technology and will not be elaborated on in detail.

[0075] When twisting multiple wires together to make a cable, the wires are easily contaminated with dust, dirt, and other impurities during movement. Although each wire is cleaned before twisting, it is inevitable that some impurities will temporarily stick to it during the actual operation, or the wires may break due to various factors during the twisting process.

[0076] If dust and other dirt are stuck on the wire harness, the performance and quality of the cable after twisting will be affected; and if the wire harness breaks and is not discovered and handled in time, the wire harness may come into contact with other unbroken wire harnesses during the breaking process, and may also cause damage to other wire harnesses. Therefore, by setting a dust cleaning and shielding component before twisting multiple wire harnesses, and then controlling the start of the dust cleaning and shielding component, the impurities on the wire harness are adsorbed and collected to keep the wire harness clean, which is beneficial to prevent the finished product from being affected by impurities. If one or more wire harnesses break during the twisting process, the dust cleaning and shielding component can adsorb the broken wire harnesses so that the broken wire harnesses can enter the inside of the dust cleaning and shielding component, which is beneficial to limit the broken wire harnesses to prevent the broken wire harnesses from damaging other wire harnesses when they break, and the debris generated when the wire harness breaks can also be collected by the dust cleaning and shielding component, which is beneficial to prevent the debris generated when the wire harness breaks from adhering to the wire harness and affecting the twisting.

[0077] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the invention as claimed.
