Multi-axis straight bar winding machine

Abstract

A multi-axis straight-strip winding machine includes a feeding mechanism, a wire feeding mechanism, a winding mechanism, and a wire clamping mechanism. The winding mechanism includes a linear drive device, a base, a rotating rod assembly, pulleys, and a drive motor. The rotating rod assembly includes rotating rods. The drive motor synchronously drives multiple rotating rods and pulleys to rotate. During winding, the wire feeding mechanism winds the first bobbin. When a wire needs to cross over to a subsequent bobbin, the drive motor first drives a fixture to rotate so that the wire-blocking block faces upwards. The wire feeding mechanism guides the wire past one side of the wire-blocking block of the bobbin to be crossed. Then, the fixture rotates in the opposite direction to reset. During this process, the wire-blocking block automatically presses and fixes the wire, thus completing the crossing. This achieves efficient and reliable automatic wire crossing, eliminating the need for the additional complex clamps required for traditional wire crossing. It also enables automated winding of multiple linearly arranged bobbins, significantly improving production efficiency and making it suitable for large-scale continuous production.

Description

Technical Field

[0001] This invention relates to the field of winding device technology, and in particular to a multi-axis straight-bar winding machine. Background Technology

[0002] A winding machine is an automated device used to wind wires onto the bobbin of electrical components, widely used in the electronics and electrical manufacturing industries. With the increasing level of industrial automation, higher demands are placed on the efficiency, precision, and applicability of winding machines. Existing winding mechanisms are generally divided into straight-strip and internal-winding types. Straight-strip winding machines arrange the bobbins in a straight line on a fixture, while internal-winding machines typically arrange the bobbins circumferentially on the fixture, with guide pins extending into the bobbin for winding. However, when winding coils that require crossing wires, the wire needs to be transferred from one bobbin to another non-adjacent bobbin. Due to space constraints and complex wire paths, there is a lack of effective positioning and temporary fixing methods when the wire crosses an intermediate bobbin. Usually, additional, independently movable wire clamps are needed to fix and guide the wire. This wire-crossing method not only increases the complexity and control difficulty of the mechanism but also results in numerous operation cycles and long processing times, becoming a bottleneck restricting the improvement of overall production efficiency. Summary of the Invention

[0003] In view of this, the present invention provides a multi-axis straight-strip winding machine to solve the above-mentioned technical problems.

[0004] A multi-axis straight-strip winding machine includes a feeding mechanism, a wire feeding mechanism, a winding mechanism, and a wire clamping mechanism. The wire feeding mechanism guides the wire and winds the bobbin. The winding mechanism includes a linear drive device, a base mounted on the linear drive device, multiple rotating rod assemblies mounted on the base, multiple pulleys mounted on the rotating rods, and a drive motor for driving the rotating rods. Each rotating rod assembly includes a rotating rod rotatably mounted on the base at both ends, with each end rotatably connected to both sides of the base. A pulley is fitted onto one end of the rotating rod. The drive motor synchronously drives multiple rotating rods and pulleys to rotate. The wire clamping mechanism is used to clamp the starting end of the wire. During the winding process, the wire feeding mechanism guides the wire to wind around the first frame. When it is necessary to cross to a subsequent frame, the drive motor drives the rotating rods and the fixture to rotate, so that the wire blocking block faces upward. The wire feeding mechanism guides the wire to pass through the wire blocking block of the frame to be crossed, so that the wire passes close to one side of the wire blocking block. The drive motor drives the rotating rod to rotate in the opposite direction to reset, so that the wire blocking block presses and fixes the wire that has passed to its side, completing the crossing action. The wire feeding mechanism continues to wind the subsequent frames.

[0005] Furthermore, the feeding mechanism includes a first three-axis moving device and a plurality of clamping assemblies disposed on the first three-axis moving device. The clamping assembly includes a first mounting plate disposed on the first three-axis moving device, an opening and closing cylinder disposed on the first mounting plate, two clamping blocks respectively disposed on the opening and closing cylinder, and a buffer pressing assembly disposed on the first mounting plate.

[0006] Furthermore, the two output ends of the opening and closing cylinder are respectively provided with clamping blocks. The clamping blocks are L-shaped. One end of the clamping block is connected to the output end of the opening and closing cylinder, and the other end is provided with a connecting block and a connecting post. Corresponding slots and holes are provided at both ends of the fixture. When the two clamping blocks are close to each other, the connecting block and the connecting post are inserted into the corresponding slots and holes.

[0007] Furthermore, the wire feeding mechanism includes a second three-axis moving device, multiple mounting brackets mounted on the second three-axis moving device, multiple guide wheels mounted on the mounting brackets, multiple wire ejection clamps mounted on the mounting brackets, multiple varnish stripping devices mounted on the mounting brackets, multiple tensioners, and multiple guide pins mounted on the mounting brackets. The guide wheels are used to guide and change the direction of the wire, the wire ejection clamps are used to temporarily fix the wire during the winding process, the varnish stripping devices are used to remove the insulating varnish layer from the ends of the wire, and the tensioners are used to control the tension of the wire during the feeding and winding process.

[0008] Furthermore, the rotating rod assembly also includes at least two locking cylinders disposed on the rotating rod, a locking element disposed at the output end of the locking cylinder, and two limiting blocks disposed on the rotating rod.

[0009] Furthermore, a T-shaped docking groove is provided on one side of the fixture, the output end of the locking cylinder moves through the rotating rod and is used to drive the locking member to move, the locking member is T-shaped, and the limiting block is used to limit the position when the fixture is placed.

[0010] Furthermore, the wire clamping mechanism is located below the winding mechanism. The wire clamping mechanism includes a third three-axis moving device, a plurality of second mounting plates disposed on the third three-axis moving device, and a plurality of wire clamps respectively disposed on the second mounting plates.

[0011] Furthermore, the multi-axis straight-strip winding machine also includes a feeding mechanism for conveying the fixture carrying multiple skeletons.

[0012] Compared with existing technologies, the multi-axis straight-strip winding machine provided by this invention arranges multiple skeletons in a straight line on the fixture. The straight-strip layout facilitates the control of the fixture to flip and cross the wire. The drive motor of the winding mechanism synchronously drives all the rotating rods to rotate via a belt, thereby causing the entire fixture and all the skeletons to flip as a whole. When crossing the wire, the rotating rods rotate, causing the skeletons to tilt to the side, resulting in the wire-blocking block facing upwards. The wire feeding mechanism controls the movement of the guide pin, so that the wire is close to the side of the wire-blocking block of the skeleton to be crossed. Subsequently, the rotating rods rotate in the opposite direction to reset. During this process, the wire-blocking block presses the wire tightly against one side of the wire-blocking block. Through mechanical movement, the positioning, tensioning, and temporary fixation of the crossing wire are completed, completely replacing the inefficient method of clamping wires one by one in traditional internal winding coils or complex lead wires. The crossing efficiency is extremely high and the reliability is good. In addition, through the coordinated operation of the feeding mechanism, the wire feeding mechanism, the winding mechanism and the wire clamping mechanism, automated winding of multiple linearly arranged skeletons is achieved, which greatly improves production efficiency and is suitable for large-scale continuous production.

[0025] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0026] like Figures 1 to 12 The diagram shown is a structural schematic of the multi-axis straight-strip winding machine provided by the present invention. The multi-axis straight-strip winding machine includes a feeding mechanism 10, a feeding mechanism 20, a wire feeding mechanism 30, a winding mechanism 40, and a wire clamping mechanism 50. It is conceivable that the multi-axis straight-strip winding machine also includes other functional modules, such as connecting components, sensors, and mounting components, etc., which are technologies well known to those skilled in the art and will not be described in detail here.

[0027] First, it should be noted that the multi-axis straight-strip winding machine is used to wind multiple bobbins 100 mounted on the fixture 200, with the bobbins 100 arranged in a straight line on the fixture 200. A T-shaped docking groove 210 is provided on one side of the fixture 200, which is used to connect with the winding mechanism 40. A wire-blocking block 110 is provided at one end of each bobbin 100, which is used to block the wire when it crosses over another wire; a detailed explanation will be provided during the winding process. The bobbins 100 and the fixture 200 are existing technologies and will not be described further here.

[0028] The feeding mechanism 10 is used to transport the fixture 200, which is equipped with a plurality of the skeletons 100, to the feeding mechanism 20.

[0029] The feeding mechanism 20 includes a first three-axis moving device 21 and a plurality of clamping assemblies 22 disposed on the first three-axis moving device 21.

[0030] The first three-axis moving device 21 is used to drive the clamping assembly 22 to move along three axes, so that after the clamping assembly 22 clamps the jig 200, it is transported to the winding mechanism 40. The clamping assembly 22 includes a first mounting plate 221 disposed on the first three-axis moving device 21, an opening and closing cylinder 222 disposed on the first mounting plate 221, two clamping blocks 223 respectively disposed on the opening and closing cylinder 222, and a buffer pressing assembly 224 disposed on the first mounting plate 221. The two output ends of the opening and closing cylinder 222 are respectively provided with the clamping blocks 223, and the opening and closing cylinder 222 drives the two clamping blocks 223 to move closer or further apart. The clamping block 223 has an L-shaped structure. One end of the clamping block 223 is connected to the output end of the opening and closing cylinder 222, and the other end is provided with a connecting block 225 and a connecting post 226. Corresponding slots and holes are provided at both ends of the fixture 200. When two clamping blocks 223 approach each other, the connecting block 225 and the connecting post 226 are inserted into the corresponding slots and holes, thereby clamping the fixture 200 for transport. The buffer pressing component 224 is used to press down on the fixture 200 to prevent it from moving when clamped, or to press down on the fixture 200 to ensure it is placed in place. It should be a limited technology and will not be described in detail here.

[0031] The wire feeding mechanism 30 includes a second three-axis moving device 31, a plurality of mounting brackets 32 disposed on the second three-axis moving device 31, a plurality of guide wheels 33 disposed on the mounting brackets 32, a plurality of wire ejection clamps 34 disposed on the mounting brackets 32, a plurality of paint stripping devices 35 disposed on the mounting brackets 32, a plurality of tensioners 36, and a plurality of guide pins 37 disposed on the mounting brackets 32.

[0032] The second and third-axis moving device 31 is used to drive the mounting frame 32 and the various components mounted on the mounting frame 32 to move along three axes, thereby controlling the winding action of the wire. The mounting frame 32 serves as a support structure to fix the other components of the wire feeding mechanism 30, forming an integral module that facilitates synchronous driving by the second and third-axis moving device 31. The guide wheel 33 is used to guide and change the direction of the wire, providing a smooth transition path, reducing friction and wear of the wire during transportation, and ensuring smooth passage of the wire. The wire retraction clamp 34 is used to temporarily fix the wire during winding, for example, when the wire is cut, the wire retraction clamp 34 will clamp the wire to prevent the wire from retracting. The varnish stripping device 35 is used to remove the insulating varnish layer from the end of the wire, exposing the metal core, which facilitates subsequent welding or electrical connection. It can control the position of the wire varnish stripping according to the needs of the process. The tensioner 36 is used to control the tension of the wire during transportation and winding, providing adjustable resistance to keep the wire at a constant and appropriate tension. This should be existing technology and will not be described in detail here.

[0033] The winding mechanism 40 includes a linear drive device 41, a base 42 mounted on the linear drive device 41, a plurality of rotating rod assemblies 43 mounted on the base 42, a plurality of pulleys 44 respectively mounted on the rotating rods 43, and a drive motor 45 for driving the rotating rods 43 to rotate. The linear drive device 41 is used to drive the winding mechanism 40 to move linearly, thereby controlling the position of the winding mechanism 40. The base 42 has a hollow rectangular frame structure to facilitate the mounting of the rotating rod assembly 43 within the base 42.

[0034] The rotating rod assembly 43 includes a rotating rod 431 with both ends rotatably mounted on the base 42, at least two locking cylinders 432 mounted on the rotating rod 431, a locking member 433 mounted on the output end of the locking cylinder 432, and two limiting blocks 434 mounted on the rotating rod 431.

[0035] The two ends of the rotating rod 431 are rotatably connected to the two sides of the base 42, and a pulley 44 is sleeved on one end of the rotating rod 431.

[0036] The output end of the locking cylinder 432 passes through the rotating rod 431 and is used to move the locking member 433. The locking member 433 is T-shaped, thus matching the structure of the docking groove 210. When the fixture 200 is placed on the rotating rod 431, the locking member 433 is inserted laterally into the docking groove 210. Then, the locking cylinder 432 drives the locking member 433 to retract. Since the two sides of the docking groove 210 will block the movement of the locking member 433 on both sides, the locking member 433 will tightly fasten the fixture 200 to the rotating rod 431 to achieve fixation. The limiting block 434 is used to limit the placement of the fixture 200 to ensure accurate placement height.

[0037] The pulleys 44 of the multiple rotating rods 43 are connected by a belt, which is wound around the output end of the drive motor 45. The drive motor 45 and the belt synchronously drive the multiple rotating rods 43 and the pulleys 44 to rotate, thereby causing the fixture 200 and the skeleton 100 to also rotate. This rotation is used for wire crossing, which will be explained in detail below in conjunction with the winding process.

[0038] The wire clamping mechanism 50 is located below the winding mechanism 40. The wire clamping mechanism 50 includes a third three-axis moving device 51, a plurality of second mounting plates 52 disposed on the third three-axis moving device 51, and a plurality of wire clamps 53 respectively disposed on the second mounting plates 52.

[0039] The third three-axis moving device 51 is used to drive the wire clamp 53 to move along three axes, thereby controlling the wire clamp 53 to switch to different positions. The wire clamp 53 is used to clamp the starting wire during winding.

[0040] Since the multiple skeletons 100 are not wound sequentially, but rather after the first skeleton 100 is wound, the process requires bypassing at least one skeleton 100 before winding onto subsequent skeletons 100. During winding, the feeding mechanism 10 conveys the fixture 200 carrying multiple linearly arranged skeletons 100 to the feeding mechanism 20. The first three-axis moving device 21 of the feeding mechanism 20 drives the clamping assembly 22 to move and clamp the fixture 200, precisely placing it onto the rotating rod 43 of the winding mechanism 40. During placement, the docking groove 210 of the fixture 200 is inserted laterally into the locking member 433 until it moves to the position of the limiting block 434. Then, the locking member 433 is pulled back under the drive of the locking cylinder 432, using the snap-fit ​​effect of the T-slot to lock the fixture 200 onto the rotating rod 431. Finally, the clamping assembly 22 releases the fixture 200 and resets. At this time, the rotating rod 431 rotates the skeleton 100 to face the guide pin 37, i.e., the skeleton 100 faces upwards, so that the guide pin located at the top can move and wind the wire. The second three-axis moving device 31 drives the mounting bracket 32 ​​to move as a whole, sending the guide pin 37 to the starting position of the first skeleton 100 that needs to be wound, generally the first skeleton 100. The wire clamp 53 moves under the drive of the third three-axis moving device 51, clamping the starting end of the wire. Then, the second three-axis moving device 31 controls the guide pin 37 to perform a winding movement, i.e., rotate around the skeleton 100. During the rotation, the wire is guided by the guide pin 37 and wound around the first skeleton 100, such as... Figure 10 As shown. Next, the wire crossing is performed. The rotating rod 431 rotates the fixture 200 ninety degrees, rotating the skeleton 100 to the side so that the wire-blocking block 110 faces upward. The second three-axis moving device 31 controls the guide pin 37 to pass over the wire-blocking block 110 of the skeleton 100 to be crossed, so that the wire passes close to the side of the wire-blocking block 110, and the wire should be located on the side of the wire-blocking block 110 facing the side of the rotating rod 431 in the reset rotation direction, such as... Figure 11As shown. Next, the rotating rod 431 drives the fixture 200 to rotate in the opposite direction to reset, so that the skeleton 100 faces upward again. Since the wire is located on the side of the wire-blocking block 110 facing the direction of rotation of the rotating rod 431, during the rotation reset process, the wire-blocking block 110 will press the wire tightly against one side of the wire-blocking block 110. This process automatically completes the positioning, tensioning and temporary fixation of the jumper wire using mechanical movement to prevent it from loosening. The guide needle 37 winds multiple skeletons 100 again in the above method. After completion, the wire-cutting device cuts the wire, and the wire clamp 53 is released. The second set of coils starts to be wound from the second empty skeleton 100 and completes the winding of all skeletons in the above method. Finally, the feeding mechanism 20 removes the finished product, replaces it with a new fixture, and begins the next cycle.

[0041] Compared with the prior art, the multi-axis straight-bar winding machine provided by the present invention arranges multiple skeletons 100 in a straight line on the fixture 200. The straight-bar layout facilitates the control of the fixture 200 to flip and cross the wire. The drive motor 45 of the winding mechanism 40 synchronously drives all the rotating rods 431 to rotate via a belt, thereby driving the entire fixture 200 and all the skeletons 100 to flip as a whole. When crossing the wire is required, the rotating rods 431 rotate 90 degrees, causing the skeleton 100 to tilt to the side, resulting in the wire blocking block 110 facing upward. The wire feeding mechanism 30 controls the movement of the guide pin 37, so that the wire is close to the side of the wire blocking block 110 of the skeleton 100 that needs to be crossed. Subsequently, the rotating rod 431 rotates in the opposite direction to reset. During this process, the wire-blocking block 110 presses the wire tightly against one side of the wire-blocking block 110, using mechanical movement to complete the positioning, tensioning, and temporary fixing of the crossing wire. This completely replaces the inefficient method of clamping wires one by one in traditional internal winding coils or complex lead wires, resulting in extremely high crossing efficiency and good reliability. In addition, through the coordinated work of the feeding mechanism 10, the feeding mechanism 20, the wire feeding mechanism 30, the winding mechanism 40, and the wire clamping mechanism 50, automated winding of multiple linearly arranged skeletons 100 is achieved, greatly improving production efficiency and making it suitable for large-scale continuous production.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
