Description

Technical Field

[0001] This invention relates to the field of wire twisting equipment, and in particular to wire twisting machines and wire twisting methods. Background Technology

[0002] A winding machine is a device used to wind wire onto a spool. After the wire on a spool is fully wound (full spool), the wire between the full spool and the wire feeding machine needs to be cut or melted off. Then the wire ends on the full spool are fixed to prevent the wire wound on the spool from loosening.

[0003] To achieve automatic fixing of wire ends, Chinese patent application No. 201910850997.2 discloses a winding reel clamp and its method of use, which discloses a method of fixing wire ends by binding them.

[0004] However, this method can only be used for binding on the winding machine, which means that the winding machine cannot continue feeding and winding work during binding, affecting efficiency. Furthermore, the binding method is neither ideal in terms of stability nor efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems existing in the prior art and to provide a wire twisting machine and a wire twisting method thereof.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A wire twisting machine, including a workbench, wherein the workbench is equipped with:

[0008] A full-wheel rotation mechanism includes a full-wheel fixing assembly and a rotation drive assembly for driving the full-wheel fixing assembly to rotate about its axis, the axis of the full-wheel fixing assembly extending longitudinally.

[0009] A thread end fixing mechanism, located next to the full-wheel rotation mechanism, is configured to clamp the thread end of the full-wheel on the full-wheel rotation mechanism;

[0010] A line-taking mechanism includes a line-taking rod whose axis is parallel to the axis of the full-wheel fixing assembly, and a line-taking drive assembly that drives the line-taking rod to revolve at least around the axis of the full-wheel fixing assembly and to move up and down longitudinally; the line-taking rod revolves between the full-wheel fixing assembly and the line-end fixing mechanism.

[0011] A thread-twisting mechanism, which is located next to the full-wheel rotation mechanism and is used to tighten the thread picked up by the thread take-up lever, includes a moving mechanism and a thread-twisting assembly driven thereto.

[0012] Preferably, the full-wheel fixing component is a chuck or an air shaft.

[0013] Preferably, the line-taking drive assembly includes a horizontal moving assembly, a rotating assembly, and a vertical moving assembly. The horizontal moving assembly is connected to the rotating assembly located above the full-wheel fixing assembly and drives the rotating assembly to translate between a first position and a second position. At the first position, the rotating assembly is coaxial with the full-wheel fixing assembly. At the second position, the rotating assembly is located outside the full-wheel fixing assembly. The vertical moving assembly is disposed on the side of the rotating assembly and drives the vertical moving assembly to revolve around the axis of the rotating assembly. The vertical moving assembly is connected to the line-taking rod.

[0014] Preferably, the line-carrying drive assembly includes a lifting assembly and a rotating assembly. The lifting assembly is connected to the rotating assembly located above the full-wheel fixing assembly and drives the rotating assembly to move up and down between a first height and a second height. At the first height, the height difference between the rotating assembly and the full-wheel fixing assembly is greater than the thickness of the full wheel. The second height is lower than the first height. The rotating assembly is coaxial with the full-wheel fixing assembly, and the side of the rotating assembly is connected to the line-carrying rod and drives the line-carrying rod to revolve around its axis.

[0015] Preferably, the line-carrying drive assembly includes a rotating assembly and a lifting assembly driven by the rotating assembly to revolve around its axis. The rotating assembly is fixedly positioned above the full-wheel fixing assembly. The lifting assembly is connected to the line-carrying rod and drives it to rise and fall. The full-wheel rotating mechanism is connected to a translation mechanism that drives it to move between a third position and a fourth position. In the third position, the full-wheel fixing assembly is coaxial with the rotating assembly. In the fourth position, the full-wheel fixing assembly is located outside the rotating assembly.

[0016] Preferably, the twisting assembly includes a frame, on which a rotating shaft is rotatably disposed, the axis of which is perpendicular to the axis of the full wheel fixing assembly. The rotating shaft is connected to a rotation drive mechanism that drives its rotation, and a twisting clamp is connected to one end of the rotating shaft facing the full wheel fixing assembly.

[0017] Preferably, one end of the rotating shaft is connected to a slip ring coaxial with it, and the other end of the slip ring is connected to the frame.

[0018] Preferably, the moving mechanism includes at least a linear translation component, which drives the twisting component to translate infinitely.

[0019] Preferably, the workbench is mounted on a mobile trolley.

[0020] Preferably, the mobile trolley is also equipped with a wire breaking mechanism and a loading / unloading mechanism. The loading / unloading mechanism includes a mobile robot, a wire wheel gripper driven by the robot, and a wire picking and gripping assembly disposed on the side of the wire wheel gripper.

[0021] The above-mentioned wire twisting method of the wire twisting machine includes the following steps:

[0022] S1, Place the full wheel on the full wheel fixing component and position the wire end in a clamping position for the wire end fixing mechanism; the full wheel fixing component is activated to fix the full wheel; the wire end fixing mechanism is activated to clamp the wire end of the full wheel.

[0023] S2, the thread taking mechanism starts, causing the thread taking rod to rotate along the winding direction of the full wheel and contact the thread between the full wheel and the thread end fixing mechanism. After that, it continues to rotate more than one revolution and stops between the two clamps of the twisting assembly. During the thread taking process, the full wheel fixing assembly drives the full wheel to cooperate with the action of the thread taking rod to release the thread.

[0024] S3, the twisting mechanism is activated so that the twisting jaws can grip the thread picked up by the take-up lever, and then the take-up lever moves upward to disengage from the thread it has picked up;

[0025] S4, the twisting mechanism starts, causing the twisting jaws to rotate a predetermined number of times to tighten the wire end.

[0026] The advantages of the technical solution of this invention are mainly reflected in:

[0027] This invention, through the coordinated operation of a full-wheel rotation mechanism, a thread-end fixing mechanism, a thread-taking mechanism, and a thread-twisting mechanism, allows the full-wheel to be removed from the winding machine for offline thread twisting when needed. This effectively reduces the time spent on online thread twisting, improving the utilization rate of the winding machine and thus increasing winding efficiency. The thread-twisting mechanism tightens the thread end into a twisted shape, creating a secure knot that effectively prevents loosening caused by vibration, resulting in higher stability. Furthermore, tightening a thread end on a full-wheel takes approximately 10 seconds less than tying a knot, leading to higher efficiency. The thread-taking drive assembly of this invention can utilize different structures to meet various needs, offering excellent flexibility and applicability.

[0028] The frame moving component of the present invention can drive the frame to feed infinitely, and can effectively meet the wire twisting requirements of I-beam wheels with a disc size of 170-255 mm, and has good applicability.

[0029] The rotating shaft of this invention features a central hole and side perforations, which facilitates cable routing or pipe connection while effectively protecting the cables and preventing them from swinging during rotation. The connecting disc also facilitates the stable installation of the twisting clamps. Furthermore, by positioning the shaft's axis through the center of the top of the opening and closing drive device, significant swinging of the clamped wire end and coil is effectively prevented during twisting, ensuring the stability of the twisting process.

[0030] The clamping block of this invention is designed in a C-shape to effectively avoid the take-up lever during operation and to ensure the reliability of the connection with the opening and closing drive mechanism. The structure of the protrusions and bosses on the claw body can effectively ensure the stability of the wire clamping, thereby ensuring that the wire can be effectively twisted together when twisting, avoiding the problem of ineffective tightening caused by loose clamping.

[0031] The structure and method of this invention are applicable not only to tightening the ends of single-wire windings on a single spool, but also to tightening the ends of double-wire and triple-wire windings on a single spool, offering good flexibility in application.

[0032] The structure and method of this invention can realize the tightening of wire ends, automatic feeding of full-loaded wire wheels and automatic feeding of empty wire wheels, and automatic winding of wire ends onto empty wire wheels. It can effectively realize the automation of the entire winding process with a high degree of automation. At the same time, the structure of this invention only requires one twisting machine to realize the twisting needs of multiple stations. The one-to-many working mode can effectively reduce the equipment procurement cost of enterprises and improve the utilization efficiency of the wire end tightening device.

[0049] The objectives, advantages, and features of this invention will be illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of applying the technical solutions of this invention, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this invention.

[0050] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0051] The twisting machine disclosed in this invention will now be described in conjunction with the accompanying drawings, as shown below. Figure 1 As shown, it includes a worktable 100, on which:

[0052] A full-wheel rotation mechanism 200 includes a full-wheel fixing component 201 and a rotation drive component 202 that drives the full-wheel fixing component 201 to rotate about its axis, wherein the axis of the full-wheel fixing component 201 extends longitudinally.

[0053] A thread end fixing mechanism 300 is located next to the full-wheel rotation mechanism 200 and is configured to clamp the thread end of the full-wheel on the full-wheel rotation mechanism 200.

[0054] The thread-taking mechanism 400 includes a thread-taking rod 401 whose axis is parallel to the axis of the full wheel fixing assembly 201, and a thread-taking drive assembly 402 that drives the thread-taking rod 401 to revolve at least around the axis of the full wheel fixing assembly 201 and to move up and down longitudinally. The thread-taking rod 401 revolves between the full wheel fixing assembly 201 and the thread end fixing mechanism 300.

[0055] The thread-twisting mechanism 500 is located next to the full-wheel rotation mechanism 200 and is used to tighten the thread picked up by the thread take-up lever. It includes a moving mechanism 501 and a thread-twisting assembly 502 driven by the moving mechanism 501.

[0056] As attached Figure 2 As shown, the full-wheel rotation mechanism 200 is used to cooperate with the actions of the thread-taking mechanism 400 and the thread-twisting mechanism 500 to drive the full-wheel rotation for thread feeding. The full-wheel fixing assembly 201 is used to fix the full-wheel with the full thread wound on it. It can be a chuck or an air shaft, preferably a three-jaw chuck. The jaws of the three-jaw chuck can be L-shaped. More preferably, the jaws have multiple steps. During operation, the three jaws are initially in a retracted state. At this time, the center hole of the full-wheel can be fitted onto the three jaws. Then, the three jaws expand outward until they all abut against the hole wall of the center hole, thereby fixing the full-wheel on the three-jaw chuck.

[0057] As attached Figure 2 As shown, the rotary drive assembly 202 includes a driven wheel 203 rotatably mounted on a support platform 207 via bearings. The driven wheel 203 is coaxial with the three-jaw chuck and is a ring gear. The driven wheel 203 is also connected to a gas or electric slip ring coaxial with it, which supplies power or air to the three-jaw chuck. The driven wheel 203 is connected to a drive wheel 205 via a transmission belt 204. The drive wheel 205 is connected to a first motor 206 that drives its rotation. The first motor 206 is located at the bottom of the platform of the support platform 207.

[0058] The support platform 207 is also provided with a tensioning wheel 208 for tensioning the transmission belt 204. The tensioning wheel 208 is rotatably mounted on a tensioning block 209. The tensioning block 209 is adjustablely mounted in a limiting groove 210 on the platform.

[0059] Of course, in other embodiments, the rotary drive component 202 may also adopt a known servo rotary platform or other feasible structure.

[0060] As attached Figure 1 Appendix Figure 3As shown, the thread end fixing mechanism 300 is located on the left side of the full wheel rotation mechanism 200. It includes a thread end clamp 301 and a linear moving device 302 that drives the thread end clamp 301 to move linearly along the second horizontal direction X (the second horizontal direction is perpendicular to the axis of the full wheel fixing assembly 201 and perpendicular to the first horizontal direction). The thread end clamp 301 is a pneumatic clamp with its clamping head facing the full wheel fixing assembly 201. The clamping head includes a connecting part 303 with an obtuse angle and a clamping mouth 304. The two clamping heads move along the longitudinal direction Z to open and close. The height of the thread end clamp 301 is higher than the top of the full wheel fixing assembly. Its specific height can be adaptively adjusted according to the position of the wire between the wire release mechanism 900 and the full wheel when the winding machine a stops winding. It is not limited here. The wire end gripper 301 is connected to the linear motion device 302 via an adapter block 305. The linear motion device 302 can be a cylinder, hydraulic cylinder, or servo linear module, etc., and is mounted on a mounting bracket 306 on the workbench 100. The moving distance of the wire end gripper 301 can be designed as needed and is not limited here.

[0061] Of course, in another embodiment, the wire end fixing mechanism 300 can also be a fixing rod, etc., and the wire end can be manually tied to the fixing rod.

[0062] As attached Figure 4 As shown, the thread take-up mechanism 400 is used to form a coil between the full wheel on the full wheel fixing assembly 201 and the thread end fixing mechanism 300 so that it can be tightened by the thread twisting mechanism 500. Specifically, the thread take-up is achieved by driving the thread take-up rod 401 to rotate around the outer circumference of the full wheel on the full wheel fixing assembly 201 through the rotating assembly 403 coaxial with the full wheel fixing assembly 201, thereby moving the thread between the full wheel and the thread end fixing mechanism 300. The thread take-up rod 401 extends a certain length below the rotating assembly 403. The specific length is designed according to needs and is not limited here.

[0063] The rotating component 403 may include a rotating platform and a turntable driven by the rotating platform to rotate, or the rotating component 403 may include a motor and a planetary gear train driven by the motor, wherein the outer ring gear of the planetary gear train rotates; or the rotating component 403 may include a geared motor and a turntable driven by the geared motor to rotate.

[0064] When the rotating component 403 and the full wheel fixing component 201 are in a coaxial state, they will interfere with the loading and unloading operation of the full wheel. Therefore, it is necessary to allow relative movement between the rotating component 403 and the full wheel fixing component 201 to generate the loading and unloading operation space.

[0065] In one embodiment, the full-wheel fixing component 201 can be kept stationary, while the rotating component 403 can be translated to be misaligned with the full-wheel fixing component 201.

[0066] As attached Figure 4 As shown, the line-carrying drive assembly 402 includes a horizontal moving assembly 404, a rotating assembly 403, and a longitudinal moving assembly 405. The horizontal moving assembly 404 is connected to the rotating assembly 403 located above the full-wheel fixing assembly 201 and drives the rotating assembly 403 to translate between a first position and a second position. In the first position, the rotating assembly 403 is coaxial with the full-wheel fixing assembly 201, and the distance between them is approximately equal to the thickness of the full wheel (the distance between the two end faces of the I-beam wheel). In the second position, the rotating assembly 403 is located outside the full-wheel fixing assembly 201, at which point the loading and unloading of the full wheel can be performed. The longitudinal moving assembly 405 is disposed on the side of the rotating assembly 403 and drives the longitudinal moving assembly 405 to revolve around the axis of the rotating assembly 403. The longitudinal moving assembly 405 is connected to the line-carrying rod 401. The horizontal moving assembly 404 can be a mechanism capable of driving the rotating assembly 403 to move linearly, including a cylinder, a hydraulic cylinder, or a servo linear module and a mounting bracket driven by it. Alternatively, the horizontal moving component 404 may be a swinging component capable of driving the vertical moving component 405 to perform horizontal swinging motion. The swinging component may include a swing arm 406, one end of which is connected to the rotating component 403 located above the full-wheel fixing component 201. When the rotating component 403 is a planetary gear train driven by a motor, the housing and / or planet carrier of the planetary gear train are rotatably connected to the swing arm 406 via bearings. The other end of the swing arm 406 is connected to a swinging drive mechanism that drives its swinging motion. The swinging drive mechanism may be, for example, a servo turntable or rotary cylinder mounted on a base.

[0067] The longitudinal moving component 405 is a cylinder that drives the thread take-up lever 401 to rise and fall. When the longitudinal moving component 405 drives the thread take-up lever 401 to move downward, the outer wall of the thread take-up lever 401 can contact the thread between the full wheel and the thread end fixing mechanism 300 and wind it into a coil. When the longitudinal moving component 405 drives the thread take-up lever 401 to move upward, the thread take-up lever 401 can be removed from the coil to facilitate twisting the thread.

[0068] In another embodiment, the full-wheel fixing component 201 can be kept stationary, while the rotating component 403 can be raised or lowered to create a sufficient height difference between it and the full-wheel fixing component 201.

[0069] At this time, the line-carrying drive assembly 402 includes a lifting assembly and a rotating assembly 403. The specific structure of the lifting assembly is known technology. It can be a sliding frame connected to a vertical drive assembly that drives it to slide up and down along the longitudinal rail. The vertical drive assembly can be a cylinder, hydraulic cylinder, or servo module. Preferably, a screw and motor combination structure can be used to drive the sliding frame. The lifting assembly is connected to the rotating assembly 403 located above the full-wheel fixing assembly 201 and drives the rotating assembly 403 to rise and fall between a first height and a second height. At the first height, the height difference between the rotating assembly 403 and the full-wheel fixing assembly 201 is greater than the thickness of the full wheel. The second height is lower than the first height. The first and second heights can be adjusted according to actual needs and are not limited here. The rotating assembly 403 is coaxial with the full-wheel fixing assembly 201. The side of the rotating assembly 403 is connected to the line-carrying rod 401 and drives the line-carrying rod 401 to revolve around its axis.

[0070] When full-wheel loading and unloading is required, the lifting assembly can drive the rotating assembly 403 to a second height. At this time, there is sufficient space between the rotating assembly 403 and the full-wheel fixing assembly 201 for full-wheel loading and unloading operations. When line picking is required, the lifting assembly moves to a first height to pick the line.

[0071] In another embodiment, the rotating component 403 can be kept stationary, while the full-wheel fixing component 201 can be translated to be misaligned with the rotating component 403.

[0072] At this time, the line-picking drive assembly 402 includes a rotating assembly 403 and a lifting assembly driven by the rotating assembly to revolve around its axis. The rotating assembly 403 is located above the full-wheel fixing assembly 201. The lifting assembly is connected to the line-picking rod 401 and drives it to rise and fall. The full-wheel rotating mechanism 200 is connected to a translation mechanism that drives it to move between a third position and a fourth position. In the third position, the full-wheel fixing assembly 201 is coaxial with the rotating assembly 403. In the fourth position, the full-wheel fixing assembly 201 is located outside the rotating assembly 403.

[0073] Specifically, the support platform 207 where the full-wheel rotation mechanism 200 is located is slidably mounted on a horizontal track via a sliding member. The sliding member is connected to a drive device that drives its linear translation. The drive device can also be a cylinder, hydraulic cylinder, linear servo module, etc. When loading and unloading are required, the translation mechanism drives the full-wheel rotation mechanism 200 to move to the outside of the rotation assembly 403 for loading and unloading.

[0074] Of course, in another embodiment, the line-picking drive assembly 402 can be implemented using a four-axis robot, and the line-picking lever 401 is connected to the outside of the lifting and rotating shaft of the four-axis robot via an adapter.

[0075] As attached Figure 1 As shown, the twisting mechanism 500 is used to twist the thread it grips into a single strand. It is located on the lower side of the full-wheel rotation mechanism 200. The moving mechanism 501 is used to drive the twisting assembly 502 to move to avoid the movement of the take-up lever 401 and to realize the twisting action.

[0076] As attached Figure 5 As shown, the moving mechanism 501 includes a linear translation component 503 and a height adjustment component 504 that drives its lifting and lowering. The linear translation component 503 drives the twisting component 502 to move along a first horizontal direction Y (the first horizontal direction is perpendicular to the axis of the full wheel fixing component 201). The height adjustment component 504 drives the clamp of the twisting component 502 to move from a height equivalent to the top of the full wheel fixing component 201 to a predetermined height above the full wheel fixing component 201.

[0077] As attached Figure 5 As shown, the height adjustment component 504 is mounted on a carrier plate 505, and includes a height adjustment driver 506 and a vertical plate 507 driven by the driver. The height adjustment driver 506 can be a cylinder, a hydraulic cylinder, or a linear servo module. The vertical plate 507 is slidably mounted on a longitudinal guide rail 508 on the carrier plate 505. The linear translation component 503 is mounted on the vertical plate 507, and the linear translation component 503 includes a translation driver 509. The translation driver 509 can be a cylinder, a hydraulic cylinder, or a linear servo module. The translation driver 509 is connected to a sliding plate 510, and the sliding plate 510 is slidably mounted on a horizontal guide rail 511 on the vertical plate 507. The wire twisting component 502 is mounted on the sliding plate 510.

[0078] As attached Figure 5 As shown, the twisting assembly 502 includes a frame 512, on which a rotating shaft 513 with its axis extending along a first horizontal direction Y is rotatably provided. The rotating shaft 513 is connected to a rotary drive mechanism 514 that drives its rotation. One end of the rotating shaft 513 facing the full wheel fixing assembly 201 is connected to a twisting clamp 515.

[0079] As attached Figure 6As shown, the rotating shaft 513 is rotatably mounted on the frame 512 via a bearing (not shown). A driven pulley 516 is coaxially mounted on the rotating shaft 513. The driven pulley 516 is connected to a driving pulley 519 via a belt 518. The driving pulley 519 is coaxially connected to the motor shaft of a second motor 520. The second motor 520 is fixed to the frame 512. The second motor 520, driving pulley 519, belt 518, and driven pulley 516 constitute the rotary drive mechanism 514. When the second motor 520 operates, it drives the rotating shaft 513 to rotate, thereby causing the twisting clamp 515 to rotate and achieve wire twisting.

[0080] As attached Figure 7 As shown, in order to avoid the wires and tubes from becoming tangled, reduce the exposure of the wires and tubes, and prevent the wires and tubes from swinging excessively during rotation, the rotating shaft 513 has a central hole 521 extending along its axial direction. The side wall of the rotating shaft 513 has a through hole 522 communicating with the central hole 521. A connecting plate 523 is provided at the lower end of the rotating shaft 513. The wires and tubes pass through the central hole 521 and the through hole 522 to connect to the twisting clamp 515.

[0081] As attached Figure 8 As shown, the twisting jaw 515 can be a known pneumatic jaw or an electric jaw. Taking a pneumatic jaw as an example, it includes a jaw cylinder 524 and two clamping blocks 525 driven by the jaw cylinder 524. The jaw cylinder 524 is coaxial with the rotating shaft 513, that is, the axis of the rotating shaft 513 passes through the center of the top of the jaw cylinder 524. At the same time, the clamping blocks 525 are symmetrically distributed on both sides of the rotating shaft 513. This can effectively prevent the wire held by the twisting jaw 515 from swinging significantly during twisting.

[0082] As attached Figure 8 As shown, the clamping block 525 is preferably C-shaped. One of the clamping parts 526 of the two clamping blocks 525 has a boss 527 on its inner side, and the other clamping part 526 has two protruding ridges 528 with a gap on its inner side. The distance between the two protruding ridges 528 is equivalent to the width of the boss 527. When the two clamping blocks 525 are closed, the boss 527 is embedded between the two protruding ridges 528. In this way, the gap between the boss 527 and the protruding ridges 528 can effectively improve the clamping stability of the wire during clamping, thereby ensuring effective twisting of the wire.

[0083] As attached Figure 6As shown, to facilitate the supply of electricity, air, or liquid to the wire twisting jaws 515, the rotating shaft 513 is connected to a slip ring 529 coaxially with it, and the slip ring 529 is fixed to the frame 512. The slip ring 529 can be a known pneumatic slip ring or an electric slip ring. One end of the slip ring 529 facing away from the full-wheel rotation mechanism 200 is connected to the frame 512 via a fixing member 530, and its opposite end is connected to the end of the rotating shaft 513 via a C-shaped connector 517.

[0084] In the above structure, the twisting machine can be set up next to a winding machine a and is specifically for twisting the full wheel at the winding machine a; of course, in another embodiment, multiple winding machines a can be arranged around the twisting machine, so that one twisting machine can twist the full wheel at multiple winding machines a.

[0085] Example 2

[0086] This embodiment is a further design based on Embodiment 1 above: as shown in the appendix. Figure 9 As shown, the workbench 100 is mounted on the mobile trolley 600. The mobile trolley 600 can be a known AGV trolley, RGV trolley, or a powered trolley that moves along a ground rail, etc. Its specific structure is known technology and is not limited here. Thus, the twisting machine can be moved to different positions, so that it can twist wire for more full wheels on the winding machine a.

[0087] In some embodiments, the full-loaded wheel on the winding machine a can be removed manually or by using a lifting tool and placed at the full-loaded wheel rotating mechanism 200, and the thread end of the full-loaded wheel can be pulled between the two clamps of the thread end fixing mechanism 300 for clamping. However, when the weight and / or volume of the full-loaded wheel is large and there are many winding machines a, manual loading and unloading is obviously inconvenient.

[0088] As attached Figure 9 Appendix Figure 10 As shown, the mobile trolley 600 is also equipped with a wire breaking mechanism 700 and a loading and unloading mechanism 800. The loading and unloading mechanism 800 includes a mobile robot 801, a wire wheel gripper 802 driven by the robot, and a wire picking and grabbing assembly 803 disposed on the side of the wire wheel gripper 802.

[0089] When a full-wheel unloading operation is required on the winding machine, the mobile robot 801 drives the thread wheel gripper 802 to grasp the full-wheel on the winding machine a. Simultaneously, the thread-picking and gripping assembly 803 grasps the thread to be melted between the melting mechanism and the full-wheel. After the melting mechanism melts the thread, the mobile robot 801 drives the thread wheel gripper 802 and the thread-picking and gripping assembly 803 to move the full-wheel onto the full-wheel fixing assembly 201, while simultaneously positioning the thread end grasped by the thread-picking and gripping assembly 803 in a position where the thread end fixing mechanism 300 can clamp it.

[0090] The specific structures of the wire breaking mechanism 700 and the loading / unloading mechanism 800 are known technologies, and they can adopt the structure disclosed in Chinese Utility Model Patent Application No. 201921497319.4. Alternatively, the wire pulley 802 can be replaced by a chuck, and the wire picking and gripping assembly 803 can adopt the structure disclosed in Chinese Patent Publication No. CN212197937U.

[0091] Furthermore, the structure of the wire breaking mechanism 700 differs slightly from the structure of the guide fuse device in the prior art with application number 201921497319.4, the difference being: as shown in the attached... Figure 11 As shown, in this embodiment, the existing partition column is replaced by an upper limit wheel 701 and the lower partition column is replaced by a lower limit wheel 703. The upper limit wheel 701 is rotatably mounted on a first cylinder 702 that drives it to move along the first horizontal direction Y. The lower limit wheel 703 is rotatably mounted on a second cylinder 704 that drives it to move along the first horizontal direction Y. Using the upper limit wheel 701 and the lower limit wheel 703 can better utilize their wheel grooves to limit the wire, thereby avoiding the wire from deviating along the first horizontal direction Y and affecting subsequent operations.

[0092] When the cylinder shafts of the first cylinder 702 and the second cylinder 704 extend, the grooves of the upper limit wheel 701 and the lower limit wheel 703 are directly opposite the inlet 706 between the two fuse blocks of the wire cutter 705 in the first horizontal direction Y; when the cylinder shafts of the first cylinder 702 and the second cylinder 704 retract, the upper limit wheel 701 and the lower limit wheel 703 are located on the side of the inlet 706 of the fuse.

[0093] As attached Figure 11As shown, the wire breaking mechanism 700 of the present invention also includes a diameter measuring sensor 707, which is used to measure the diameter of the wire. By measuring the diameter of the wire, the wire reels can be easily classified. The specific structure of the diameter measuring sensor 707 is known technology and is not limited here. The diameter measuring sensor 707 is located below or above the wire breaker. Preferably, the diameter measuring sensor 707 is located below the wire breaker, which makes the structure more compact. A wire clamping claw 308 is provided above the wire breaker.

[0094] Example 3

[0095] This embodiment discloses the winding method of the above-mentioned winding machine, which includes the following steps:

[0096] S1, as attached Figure 12 As shown, the full wheel b is placed on the full wheel fixing component 201 and the wire end is positioned where the wire end fixing mechanism 300 can clamp it. The full wheel fixing component 201 is activated to fix the full wheel; the wire end fixing mechanism 300 is activated to clamp the wire end of the full wheel. After the full wheel is placed on the full wheel fixing component 201 by hand and the wire end is pulled between the two clamps of the wire end clamping claw 301, the full wheel fixing component 201 can be activated by manually pressing the start button to fix the full wheel. At the same time, the two clamps of the wire end clamping claw 301 close to clamp the wire end.

[0097] S2, Subsequently, the thread-taking mechanism 400 is activated, causing the thread-taking rod 401 to rotate along the winding direction of the full wheel and contact the thread between the full wheel and the thread-end fixing mechanism. After that, it continues to rotate more than one revolution and stops between the two clamping blocks of the twisting assembly. During the thread-taking process, the full wheel fixing assembly drives the full wheel to cooperate with the action of the thread-taking rod to release the thread.

[0098] Specifically, the horizontal moving component 404 of the thread-taking mechanism 400 drives the rotating component 403 to move from the second position to the first position. Then, the vertical moving component 405 drives the thread-taking lever 401 to move downward. Next, the rotating drive mechanism 514 drives the thread-taking lever 401 to rotate counterclockwise, as shown in the attached diagram. Figure 13 -Appendix Figure 15As shown, the take-up lever 401 contacts the first thread c1 between the thread end clamping assembly and the full wheel, causing the first thread to rotate around the full wheel once and continue rotating until it is positioned between the two clamps. At this time, a coil c2 is formed on the take-up lever 401. Simultaneously, the take-up lever 401 bends the second thread c3 between the full wheel and the thread end clamping assembly into a V-shape, forming the first segment c4 and the second segment c5. The coil, the first segment c4, and the second segment c5 constitute the thread picked up by the take-up lever. During the continued revolution of the take-up lever 401 after contacting the thread, the full wheel rotation mechanism 200 drives the full wheel to rotate and release the thread. The releasing speed matches the rotation speed of the take-up lever 401 to keep the pulled thread taut.

[0099] S3, the twisting mechanism 500 is activated, causing the twisting jaws 515 to grip the thread picked up by the take-up lever 401. Then the take-up lever 401 moves upward and disengages from the coil, the first section and the second section.

[0100] Specifically, the height adjustment component 504 of the twisting mechanism 500 moves the twisting jaws 515 to a predetermined height. At this time, the notches of the two clamping blocks of the twisting jaws 515 face upwards, as shown in the attached figure. Figure 5 As shown in the attached document. Figure 15 As shown, the linear translation component 503 drives the twisting component 502 to move towards the take-up lever 401. The two clamping blocks 525 of the twisting jaws 515 contact the first segment c4 and the second segment c5 and continue to move towards the full-load reel until the clamping mouths 304 of the two clamping blocks 525 are located on both sides of the coil, and the take-up lever 401 is located at the C-shaped notch of the two clamping blocks 525, as shown in the attached diagram. Figure 16 As shown. Subsequently, the gripper cylinder 524 of the twisting gripper 515 drives the two clamping blocks 525 to close, clamping the first segment c4, the second segment c5, and the coil c2. Then, the longitudinal moving assembly 405 drives the take-up lever 401 to move upward, thereby disengaging it from the coil, the first segment, and the second segment.

[0101] S4, the twisting mechanism 500 is activated, causing the twisting gripper 515 to rotate a predetermined number of times to tighten the wire end. Specifically, the second motor of the rotary drive mechanism 514 is activated to drive the twisting gripper 515 to rotate, thereby tightening the first segment, the second segment, and the coil it grips into a bundle. Of course, during the twisting process, the full wheel can simultaneously release the wire, or it can not release the wire. At the same time, the wire end fixing mechanism can loosen the wire end, or it can not loosen the wire end.

[0102] After the twisting is completed, all mechanisms are reset, and the full reel can be removed from the full reel fixing mechanism via the loading and unloading mechanism 800. Simultaneously with the twisting, the loading and unloading mechanism 800 can install the empty reel onto the winding machine and wind the wire end onto the empty reel.

[0103] When the twisting machine is mounted on the moving trolley 600 and the moving trolley 600 is equipped with a wire breaking mechanism 700 and a loading / unloading mechanism 800, when an empty wheel on a winding machine completes winding and a full wheel needs to be twisted, the moving trolley 600 moves to the winding machine. In step S1, the full wheel is removed from the winding machine a by the loading / unloading mechanism 800 and placed on the full wheel rotating assembly 403. At the same time, the end of the wire on the full wheel is moved synchronously by the wire picking and gripping assembly of the loading / unloading mechanism 800 to a position where the end fixing mechanism 300 can clamp it. At this time, a sensor can be used to determine whether there is a full wheel on the full wheel rotating assembly 403. If there is a full wheel, the full wheel fixing assembly 201 fixes the full wheel. At the same time, the linear moving device 302 drives the end clamp 301 to move towards the full wheel until the two clamps of the end clamp 301 are located on the upper and lower sides of the end of the wire. Then, the pneumatic clamp drives the two clamps to close and clamp the end of the wire.

[0104] Of course, before the loading and unloading mechanism 800 performs the full-wheel unloading, the wire between the full-wheel and the wire feeding mechanism 900 needs to be melted. The process of the loading and unloading mechanism 800 driving the wire picking and gripping assembly 803 to pick up the wire between the full-wheel and the wire feeding mechanism 900 to the melting mechanism is a known technology and will not be described in detail here.

[0105] Before the wire cutter 705 melts the thread located between its two fuse blocks, the wire clamping jaws on the wire cutter hold the thread between its two jaws, and the thread picking and gripping assembly 803 grips the thread between the full wheel and the lower limit wheel 703. Of course, while the thread picking and gripping assembly 803 grips the thread, the thread pulley jaws 802 grip the full wheel. Subsequently, the wire cutter can melt the thread located between its two fuse blocks. After melting, the loading and unloading mechanism 800 can move the full wheel and the thread end synchronously.

[0106] The process of installing the empty wheel onto the winding shaft of the winding machine a via the loading and unloading mechanism 800 and winding the wire end at the melting mechanism onto the empty wheel is also a known technology and will not be described in detail here.

[0107] This invention has many other embodiments, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of this invention.
