Description

Technical Field

[0001] This invention relates to the field of winding machine technology, and in particular to an automatic winding mechanism with stepped bending and tail wire attachment functions. Background Technology

[0002] Coils, as the core component of electromagnetic conversion, are widely used in various electrical products and electronic devices such as transformers, inductors, motors, and relays. Their manufacturing quality directly affects the performance and stability of the entire product. Traditional coil winding is usually done by a winding machine, the basic process of which involves continuously and neatly winding enameled wire or other conductors onto the coil frame to form a winding. For most ordinary coils, after winding, it is usually sufficient to simply cut and fix the starting and ending wires.

[0003] However, with the continuous expansion of application scenarios, higher and more specific requirements are being placed on the performance and structure of the coil. For example, in order to meet specific installation space and electrical connection requirements, there are extremely stringent regulations regarding the handling of the coil tail wire. The coil body to be manufactured in this invention is as follows... Figure 10 As shown, it includes a coil frame 110 and a coil 120 wound on the coil frame 110. The coil 120 is made of a single conductor and includes a starting wire 130, a winding 140, a first tail wire 150, and a second tail wire 160. After the winding 140 is wound, the first tail wire 150 needs to be bent at the middle of the coil frame 110 and made to adhere tightly to the winding 140, while the second tail wire 160 needs to be spaced apart from the winding 140 and bent.

[0004] Currently, most existing winding equipment cannot automatically complete such complex tail wire bending and positioning. After winding, operators often need to manually perform subsequent processing such as bending and attaching. This method has extremely low production efficiency, high labor costs, and makes it difficult to guarantee product consistency. Summary of the Invention

[0005] In view of this, the present invention provides an automatic winding mechanism with stepped bending and tail wire attachment functions to solve the above-mentioned technical problems.

[0006] An automatic winding mechanism with stepped bending and tail wire attachment functions includes a three-axis moving mechanism, a wire bending mechanism mounted on the three-axis moving mechanism, and a winding mechanism. The wire bending mechanism includes a vertical moving device, a two-axis moving mechanism mounted on the vertical moving device, and a second guide wheel mounted on the two-axis moving mechanism. The winding mechanism includes a frame, a first mold assembly mounted on the frame, a second mold assembly mounted on the frame, a clamping assembly mounted on the frame, and a guide assembly mounted on the second mold assembly. The two ends of the coil bobbin are respectively mounted on the first mold assembly and the second mold assembly. A rotatably mounted pressure block is provided on the second mold assembly. The guide assembly includes a... The guide block is movable on the pressure block, a waist-shaped hole is provided on the guide block, a connecting shaft passes through the pressure block, and a third spring is provided between the guide block and the pressure block. One end of the guide block abuts against the third spring, and the other end is provided with a guide slope. Both ends of the connecting shaft are inserted into the pressure block and pass through the waist-shaped hole. When bending the wire, the pressure block presses on part of the first tail wire. The three-axis moving mechanism drives the wire bending mechanism to move. During the movement, the second guide wheel drives the wire to bend. When the wire is bent, it slides into the space between the guide block and the winding through the guide slope. The clamping assembly clamps the bent part of the first tail wire, so that the tail wire clamped by the clamping assembly is in close contact with the winding, while the tail wire not clamped by the clamping assembly is suspended from the winding.

[0007] Furthermore, the automatic winding mechanism with stepped bending and tail wire attachment functions also includes a wire laying mechanism and a wire straightening mechanism mounted on the three-axis moving mechanism. The wire laying mechanism is used to guide the wire and transport the wire to the wire straightening mechanism via guide wheels.

[0008] Furthermore, the winding mechanism includes a first guide wheel disposed on the three-axis moving mechanism and a first hot air gun disposed on the three-axis moving mechanism. The first hot air gun is located between the first guide wheel and the winding mechanism, such that the output direction of the first hot air gun is directed toward the wire after passing through the first guide wheel.

[0009] Furthermore, the first mold assembly includes a first drive shaft movably mounted on the frame, a first mold plate mounted on the first drive shaft, a first fixing seat mounted on the first mold plate, a first spring mounted between the first fixing seat and the first mold plate, and a wire clamp assembly mounted on the first mold plate. The first fixing seat is inserted into the first mold plate and is used to mount the coil frame. The first fixing seat is provided with a wire groove for accommodating the bent tail wire.

[0010] Furthermore, the height of the groove is higher than the height of the first tail wire, so that the second tail wire located in the groove will be suspended from the winding.

[0011] Furthermore, the second mold assembly includes a second drive shaft movably mounted on the frame, a second mold plate mounted on the second drive shaft, a second fixed seat mounted on the second mold plate, a movable rod inserted into the second mold plate, a crossbar inserted into the movable rod, a limiting rod mounted on the movable rod, a rotating shaft inserted into the second mold plate, and a second spring disposed between the pressure block and the movable rod, wherein the pressure block is rotatably mounted on the rotating shaft.

[0012] Furthermore, the winding mechanism also includes a drive assembly disposed on the frame, a feeding assembly disposed on the frame, and a heating assembly disposed on the frame.

[0013] Furthermore, the clamping assembly includes a multi-axis moving device, a clamping cylinder disposed on the multi-axis moving device, a plurality of limiting shafts disposed on the clamping cylinder, two clamping plates disposed on the limiting shafts, and a plurality of fourth springs sleeved on the limiting shafts.

[0014] Furthermore, the clamping plate is provided at one end of the plurality of limiting shafts facing each other, and the limiting at the other end is provided on the output end of the clamping cylinder. One end of the fourth spring is fixed to the output end of the clamping cylinder, and the other end abuts against the clamping plate.

[0015] Compared with existing technologies, the automatic winding mechanism with stepped bending and tail wire attachment functions provided by this invention first presses down the pressure block of the winding mechanism to hold down part of the first tail wire, completing the initial positioning. Then, the three-axis moving mechanism drives the winding mechanism and the wire bending mechanism to move in the direction of the starting wire. Under the buffer and guidance of the guide inclined surface of the guide component and the third spring, the first tail wire is bent and located in the wire groove. Since the height of the wire groove is higher than the height of the first tail wire, the tail wire will naturally be suspended. The clamping plate of the clamping component clamps the suspended wire, thereby making the first tail wire tightly attached to the winding, while the second tail wire is spaced apart from the winding. Finally, the heating component achieves tight adhesion. The whole process is precise and reliable, perfectly realizing the automated bending and fixing of special coil tail wires.

[0030] 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.

[0031] like Figures 1 to 13 The diagram shows the structure of the automatic winding mechanism with stepped bending and tail wire attachment functions provided by the present invention. The automatic winding mechanism with stepped bending and tail wire attachment functions includes a wire laying mechanism 10, a three-axis moving mechanism 20, a wire straightening mechanism 30 mounted on the three-axis moving mechanism 20, a wire bending mechanism 40 mounted on the three-axis moving mechanism 20, and a winding mechanism 50.

[0032] First, it should be noted that the coil body to be wound includes a coil frame 110 and a coil 120 wound on the coil frame 110. For example... Figure 10 As shown, the coil 120 is made of a single conductor and includes a starting wire 130, a winding 140, a first tail wire 150, and a second tail wire 160. After the winding 140 is wound, the first tail wire 150 needs to be bent at the middle of the coil frame 110 and made to adhere tightly to the winding 140. The second tail wire 160 needs to be spaced apart from the winding 140 and bent, which is necessary for product installation.

[0033] The wire guiding mechanism 10 is used to guide the wires, which are then transported to the coil forming mechanism 30 via guide wheels. In this embodiment, the wires used are several thin wires bonded together to improve the quality of the coil after winding. Therefore, multiple wires will converge together after passing through the guide wheels of the wire guiding mechanism 10. The wire guiding mechanism 10 should be considered prior art and will not be described in detail here.

[0034] The three-axis moving mechanism 20 is used to drive the three-axis movement of the straightening mechanism 30 and the wire bending mechanism 40. It should be existing technology and will not be described in detail here.

[0035] The assembly line mechanism 30 includes a first guide wheel 31 mounted on the three-axis moving mechanism 20, and a first hot air gun 32 mounted on the three-axis moving mechanism 20.

[0036] The first hot air gun 32 is located between the first guide wheel 31 and the winding mechanism 50, such that the output direction of the first hot air gun 32 is towards the wire after passing through the first guide wheel 31. The first hot air gun 32 heats the wire, so after the wire is guided and bundled by the first guide wheel 31, the first hot air gun 32 causes several small wires that were originally bundled together to bond together. It is conceivable that the wire is enameled wire, which can be softened by heating and then bonded together with multiple wires. The wire used is likely existing technology and will not be elaborated further here. Simultaneously, the coil to be wound can also be wound using a single wire.

[0037] The wire bending mechanism 40 includes a vertical moving device 41, a wire clipping clamp 42 disposed on the vertical moving device 41, a two-axis moving mechanism 43 disposed on the vertical moving device 41, and a second guide wheel 44 disposed on the two-axis moving mechanism 43.

[0038] The vertical moving device 41 is used to synchronously drive the wire-cutting clamp 42 and the second guide wheel 44 to move vertically for adjustment. The two-axis moving mechanism 43 is used to independently control the two-axis movement of the second guide wheel 44. The second guide wheel 44 is used to bend the wire and avoid obstacles when bending the wire is not required, so it needs to be controlled separately. The specific movement process will be described below in conjunction with the winding process. The wire-cutting clamp 42 is used to clamp the wire and move it to send the wire to the winding mechanism 50 for fixing the wire, or to cut the tail wire after winding and clamp the remaining wire to send it back to the winding mechanism 50 for the next winding, thus completing the cutting of the tail wire.

[0039] The winding mechanism 50 includes a frame 51, a first mold assembly 52 disposed on the frame 51, a second mold assembly 53 disposed on the frame 51, a drive assembly 54 disposed on the frame 51, a clamping assembly 55 disposed on the frame 51, a feeding assembly 56 disposed on the frame 51, a heating assembly 57 disposed on the frame 51, and a guide assembly 58 disposed on the second mold assembly 53.

[0040] The frame 51 is used to support the above-mentioned functional modules. Therefore, the frame 51 is provided with a variety of functional structures, such as screws, bolts, through holes, etc., to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs, and will not be described in detail here.

[0041] The first mold assembly 52 includes a first drive shaft 521 movably disposed on the frame 51, a first mold plate 522 disposed on the first drive shaft 521, a first fixing seat 523 disposed on the first mold plate 522, a first spring 524 disposed between the first fixing seat 523 and the first mold plate 522, and a wire clamp assembly 525 disposed on the first mold plate 522.

[0042] One end of the first drive shaft 521 is connected to the drive assembly 54, and the other end is provided with the first mold plate 522. The first drive shaft 521 can rotate and move axially under the drive of the drive assembly 54, thereby driving the first mold plate 522 and the first fixed seat 523 to rotate and move axially, so as to perform rotational winding and mold separation or mold closing. The first fixed seat 523 is inserted into the first mold plate 522 and is used to set the coil frame 110. The first fixed seat 523 is provided with a wire groove 526, which is used to accommodate the bent tail wire. The height of the wire groove 526 is higher than the height of the first tail wire 150, so that the second tail wire 160 located in the wire groove 526 will be suspended from the winding 140, thereby avoiding sticking during heating. A detailed explanation will be given below in conjunction with the winding process. The first spring 524 abuts against the first fixed seat 523 and the first mold plate 522, thereby pushing the first fixed seat 523 away from the first mold plate 522 in a free state through its own elastic force. When the first mold assembly 52 and the second mold assembly 53 are closed, the first fixed seat 523 is forced back and compresses the first spring 524, thereby giving the first fixed seat 523 a certain buffering capacity to prevent damage to the coil frame 110 during mold closing. The wire-starting clamp assembly 525 rotates together with the first mold plate 522. The wire-starting clamp assembly 525 is used to clamp the starting wire of the coil. The wire-starting clamp assembly 525 can clamp in a free state through the spring to clamp the starting wire of the coil. The wire-starting clamp assembly 525 should be prior art and will not be described in detail here.

[0043] The second mold assembly 53 includes a second drive shaft 531 movably mounted on the frame 51, a second mold plate 532 mounted on the second drive shaft 531, a second fixed seat 533 mounted on the second mold plate 532, a movable rod 534 inserted into the second mold plate 532, a crossbar 535 inserted into the movable rod 534, a limiting rod 536 mounted on the movable rod 534, a rotating shaft 537 inserted into the second mold plate 532, a pressure block 538 rotatably mounted on the rotating shaft 537, and a second spring 539 disposed between the pressure block 538 and the movable rod 534.

[0044] The second mold assembly 53 is similar to the upper mold assembly of a winding jig suitable for horizontal entry and exit of winding start and end wires disclosed in application number CN202511020490.6. When the crossbar 535 is moved by the external assembly, the movable rod 534 will move together. The movement of the movable rod 534 will cause one end of the pressure block 538 to rotate around the rotating shaft 537, so that the other end of the pressure block 538 is in close contact with the first end wire 150. When the external pushing assembly is reset, the movable rod 534 will automatically reset through the elastic element between the second mold plate 532 and the movable rod 534. The reset of the movable rod 534 will cause the limiting rod 536 to move, so that the pressure block 538 rotates and resets, no longer pressing the first end wire 150. Its pressing and reset process and structure should be the same as the prior art, and will not be described in detail here. The width of the pressure block 538 is smaller than the width of the coil frame 110, so it only presses down part of the wire, so that the wire will be in the middle of the coil frame 110 at the bending point.

[0045] However, in this application, horizontal bending and close contact with the winding 140 are required to press down the first tail wire 150. Therefore, a guide component 58 is also provided on the pressing block 538. The guide component 58 includes a guide block 581 movably disposed on the pressing block 538, an oblong hole 582 disposed on the guide block 581, a connecting shaft 583 passing through the pressing block 538, and a third spring 584 disposed between the guide block 581 and the pressing block 538. One end of the guide block 581 abuts against the third spring 584, and the other end is provided with a guide slope 585. The connecting shaft 583 is inserted into the pressure block 538 at both ends and passes through the waist-shaped hole 582. The third spring 584 pushes the guide block 581 away from the pressure block 538 in a free state by its own elastic force and is limited by the two ends of the waist-shaped hole 582. Thus, the guide block 581 will automatically retract when subjected to force, and after the wire is bent, it slides into the bottom of the guide block 581 through the guide slope 585, that is, between the guide block 581 and the winding 140, to ensure tight contact.

[0046] The drive assembly 54 consists of a rotary motor, belt, lead screw moving device, coupling, and connecting components, and is used to drive the second drive shaft 531 and the first drive shaft 521 to rotate and move axially, thereby realizing the winding action and the mold opening and closing action. The drive assembly 54 is similar to the synchronous transmission mechanism in a hollow coil winding machine disclosed in patent application number CN202321061739.4, therefore the drive assembly 54 should be considered prior art, and will not be described in detail here.

[0047] The clamping assembly 55 includes a multi-axis moving device 551, a clamping cylinder 552 disposed on the multi-axis moving device 551, a plurality of limiting shafts 553 disposed on the clamping cylinder 552, two clamping plates 554 disposed on the limiting shafts 553, and a plurality of fourth springs 555 sleeved on the limiting shafts 553.

[0048] The clamping plate 554 is provided at one end of each of the multiple limiting shafts 553 facing each other, and the limiting at the other end is provided on the output end of the clamping cylinder 552. One end of the fourth spring 555 is fixed to the output end of the clamping cylinder 552, and the other end abuts against the clamping plate 554, so that the clamping plate 554 has a certain buffering effect when the clamping cylinder 552 clamps, avoiding damage to the wire. The pressure block 538 is used to press down the part of the first tail wire 150 before bending, while the clamping assembly 55 is used to clamp and press down the part of the first tail wire 150 after bending.

[0049] The unloading component 56 is used to lift and support the completed coil frame after bending. The coil frame is placed on the unloading component 56 after the first and second molds are separated. In this embodiment, two heating components 57 are provided and face the upper and lower sides of the coil respectively. Since the first tail wire 150 needs to be tightly bonded to the winding 140, after the clamping component 55 clamps and presses down the bent part of the first tail wire 150, the heating component 57 softens the varnish on the outside of the wire and bonds it together.

[0050] During winding, the two ends of the coil frame 110 are first positioned between the first fixing seat 523 and the second fixing seat 533, respectively. The wire is clamped by the wire cutter clamp 42 and fed into the wire-starting clamp assembly 525 for clamping, thus completing the wire starting and fixing. Next, the second mold assembly 53 and the first mold assembly 52 rotate synchronously. Simultaneously, the three-axis moving mechanism 20 drives the wire-forming mechanism 30 to move along the coil frame, causing the wire to wind around the coil frame 110 one turn at a time. After winding is complete, an external pushing assembly moves the crossbar 535, causing the pressure block 538 to rotate and press against a portion of the first tail wire 150. Figure 11 As shown. Next, the three-axis moving mechanism 20 drives the assembling mechanism 30 and the conductor bending mechanism 40 to move in the direction of the starting line, while simultaneously rising a certain height to avoid the first fixed seat 523. During the movement, the second guide wheel 44 causes the conductor to deflect and bend, as shown. Figure 12 As shown. When the first tail wire 150 is above the wire groove 526, the first tail wire 150 is bent at a 90-degree angle. It is then lowered so that the first tail wire 150 falls into the wire groove 526. Then, the clamping assembly 55 clamps the bent portion of the first tail wire 150, as shown. Figure 13 As shown, because the height of the wire groove 526 is higher than the height of the first tail wire 150, the tail wire clamped by the clamping component 55 will be in close contact with the winding 140, while the tail wire located in the wire groove 526 and not clamped by the clamping component 55 will be suspended from the winding 140. Finally, the heating component 57 heats the wire, causing the winding 140 itself and the first tail wire 150 to stick together with the winding 140. Finally, the tail wire is cut short by the wire clip 42 before being cut into finished products.

[0051] Compared with the prior art, the automatic winding mechanism with stepped bending and tail wire attachment functions provided by the present invention first presses down the pressure block 538 of the winding mechanism 50 to press down part of the first tail wire 150, completing the initial positioning. Then, the three-axis moving mechanism 20 drives the wire forming mechanism 30 and the wire bending mechanism 40 to move in the direction of wire raising. Under the buffer and guidance of the guide inclined surface 585 of the guide component 58 and the third spring 584, the first tail wire 150 is bent and located in the wire groove 526. Since the height of the groove 526 is higher than that of the first tail wire 150, the tail wire will naturally suspend in the air. The clamping plate 554 of the clamping assembly 55 clamps the suspended wire, thereby making the first tail wire 150 stick tightly to the winding 140, while the second tail wire 160 is spaced apart from the winding 140. Finally, the heating assembly 57 achieves tight adhesion. The whole process accurately and automatically realizes the automated bending and fixing of the special coil tail wire.

[0052] 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.
