Description

Technical Field

[0001] The present invention relates to the technical field of enameled wire processing, and particularly relates to a magnetic force-guided automatic enameled wire winding system. Background Art

[0002] The winding of enameled wire is a key process in electronic manufacturing and motor production. The core goal is to achieve uniform arrangement, precise control, and avoid damage of the enameled wire during the winding process. Flat enameled wire refers to enameled wire with a rectangular cross-section of the conductor. Its specifications are usually expressed as a combination of thickness and width. Compared with traditional round enameled wire, it has higher efficiency and a wider range of application scenarios. In addition, the winding of flat enameled wire mostly needs to cooperate with a special flat coil winding machine to precisely control the arrangement and tension of the enameled wire.

[0003] In this regard, the present application designs a magnetic force-guided automatic enameled wire winding system. When the existing flat coil winding machine is used to wind a flat enameled wire with a small thickness and a large width into a rectangular shape, it mostly adopts the method of intermittently reciprocating rotation of the bending guide die for gradual winding, and there is no need to support the internal cavity of the wound flat enameled wire. The winding efficiency of this method needs to be improved; if the method of supporting and winding the internal cavity of the wound flat enameled wire is adopted, due to the small thickness of the wire, it is more likely to bend or twist when subjected to tension or friction, resulting in an irregular shape of the flat enameled wire coil or damage to the wire. Especially during rapid winding, the problem of wire arrangement is more prominent. Summary of the Invention

[0029] The wire feeding part 6 includes slide rails 61 commonly installed at positions corresponding to the rectangular openings on the two support legs of the base 1. A first lead screw 62 is rotatably installed through the two support legs of the base 1. A sliding seat 63 that is threadedly connected to the first lead screw 62 and slidably connected to the slide rails 61 is provided. An outlet pipe 64 is installed through the upper end of the sliding seat 63. A waist-shaped connecting plate 65 is fixedly sleeved on the front side of the outer wall of the outlet pipe 64. A U-shaped sleeve plate 66 is installed on the upper side of the front end of the waist-shaped connecting plate 65.

[0030] An annular sleeve plate 51 is fixedly sleeved on the upper end of the support cylinder 5. A pneumatic push rod 52 is installed on the upper end of the U-shaped frame 2 through a mounting seat. The telescopic end of the pneumatic push rod 52 is hinged to the annular sleeve plate 51. Limiting rollers 73 are jointly rotatably installed on the inner walls of the two vertical sections of the U-shaped plate 72.

[0031] During specific implementation: First of all, the winding part 8 in this application adopts the method of supporting and winding the internal cavity of the wound flat enameled wire, and can perform high-speed winding. The left circular mounting platform 81 is initially retracted into the barrel-shaped mounting plate 3, and multiple support plates 833 are initially retracted into the right circular mounting platform 81, and the left ends of the multiple support plates 833 are flush with the left end of the U-shaped extension plate 82. At this time, the left and right electromagnetic suction plates 843 are both located outside the U-shaped frame 2. It should be noted that the left and right electromagnetic suction plates 843 are not symmetrically arranged left and right, but are set according to the stroke positions of the left and right L-shaped connecting plates 844. First, the left and right second lead screws 842 are controlled to rotate synchronously by the double-shaft motor 841. The left and right second lead screws 842 drive the corresponding electromagnetic suction plates 843 to approach each other respectively. At this time, the left and right electromagnetic suction plates 843 are controlled to start working. The right electromagnetic suction plate 843 will be tightly magnetically attracted to the right L-shaped connecting plate 844. The right L-shaped connecting plate 844 will drive the rectangular connecting plate 832 to move leftward through the connecting slide rod 831. The rectangular connecting plate 832 will drive the corresponding support plates 833 to move leftward through multiple rectangular sliding strips 834. During this period, as the right electromagnetic suction plate 843 moves leftward, the left electromagnetic suction plate 843 will also move rightward and will contact the left L-shaped connecting plate 844 and be tightly magnetically attracted to the left L-shaped connecting plate 844. The left electromagnetic suction plate 843 will drive the annular connecting plate 845 to move rightward through the left L-shaped connecting plate 844 until the annular connecting plate 845 drives the circular mounting platform 81 to move rightward to a suitable position. When the left circular mounting platform 81 and multiple support plates 833 have all moved to suitable positions, the left and right electromagnetic suction plates 843 are controlled to stop working.

[0032] It should be noted that under the action of the tension spring, multiple support plates 833 are initially in a state of approaching each other. After the left circular mounting platform 81 moves to the right to an appropriate position, the left ends of multiple support plates 833 will be inserted into the left U-shaped extension plate 82 and the left receiving groove. During this period, under the tension of the alignment slide bar 811, multiple support plates 833 will drive the corresponding rectangular slide bars 834 to move away from each other along the X-shaped slide groove, so that the outer walls of multiple support plates 833 are closely attached to the inner wall of the left receiving groove, and the trapezoidal slide plate 835 and multiple guiding slide plates 836 will respectively extend out of the corresponding mounting slide grooves under the action of the compression spring.

[0033] Before winding, it should be noted that the telescopic end of the pneumatic push rod 52 is initially in a retracted state. At this time, the support cylinder 5 is in an inclined state. First, control the telescopic end of the pneumatic push rod 52 to extend. The telescopic end of the pneumatic push rod 52 will drive the support cylinder 5 to rotate around the axis of the support shaft through the annular sleeve plate 51 until the support cylinder 5 becomes vertical. At this time, the annular sleeve plate 51 will drive the C-shaped plate one 72 to rotate synchronously through the stepped slide bar 71, and the C-shaped plate one 72 will drive the limiting roller 73 to rotate synchronously. When the limiting roller 73 rotates to directly above multiple support plates 833, the outer wall of the limiting roller 73 will be closely attached to multiple guiding slide plates 836 at this time. It should be noted that the stepped slide bar 71 is at the maximum extended distance at this time and will not continue to press down on multiple guiding slide plates 836. And under the action of the compression spring, the rectangular slide plate 753 will drive the winding guiding plate 752 to be located on the left side of the support slide bar 751 through the front and rear two support rods 754. The sliding seat 63 is initially also located at a position corresponding to the winding guiding plate 752. At this time, the electromagnetic suction plate one 67 can be controlled to start working and tightly magnetize on the winding guiding plate 752.

[0034] During winding, the flat enameled wire to be wound is conveyed forward by an external wire feeding device. The flat enameled wire will pass through the sliding seat 63 and continue to be conveyed forward into the wire outlet pipe 64. At this time, the flat enameled wire will pass through the guiding slide hole at the lower end of the winding guiding plate 752, and then the flat enameled wire will be conveyed forward along the outer walls of the left upper guiding slide plate 836 and the left end of the trapezoidal slide plate 835 in sequence. Under the guiding action of the trapezoidal slide plate 835, the front end of the flat enameled wire will be bent and deformed along the inclined surface end of the trapezoidal slide plate 835 and embedded into the flat enameled wire embedding groove on the left U-shaped extension plate 82. Then, control the external wire feeding device to stop conveying forward, so as to achieve the effect of quickly connecting the front end of the flat enameled wire with the left U-shaped extension plate 82, which is convenient for subsequent winding work.

[0035] Then, at the initial stage of winding the enameled wire, it needs to start slowly to avoid excessive stretching or slipping of the wire due to inertia. First, the servo motor 813 drives the barrel-shaped mounting plate 3 to rotate half a turn, and then the rotation speed of the barrel-shaped mounting plate 3 is gradually increased to an appropriate speed. The barrel-shaped mounting plate 3 will drive the left circular mounting table 81 to rotate under the cooperation of the mating chute and the mating slide bar 812. The left circular mounting table 81 drives the multiple support plates 833 to rotate synchronously through the left U-shaped extension plate 82. While the multiple support plates 833 drive the rectangular connecting plate 832 to rotate, they also drive the right U-shaped extension plate 82 and the right circular mounting table 81 to rotate synchronously.

[0036] It should be noted that a plurality of alignment magnets 814 on the right circular mounting table 81 are initially magnetically attracted to a plurality of alignment magnets 814 on the inner wall of the annular plate 4. At this time, the left U-shaped extension plate 82 drives the flat enameled wire to rotate for winding work. At the same time, the external motor controls the rotation of the first lead screw 62. The first lead screw 62 drives the wire outlet pipe 64 to move uniformly to the right through the sliding seat 63. The wire outlet pipe 64 drives the U-shaped sleeve plate 66 to move uniformly to the right through the waist-shaped connecting plate 65. The U-shaped sleeve plate 66 drives the winding guide plate 752 to move uniformly to the right through the electromagnetic suction plate 67, so as to achieve the effect of the flat enameled wire moving uniformly to the right for easy winding and forming. Until just before the flat enameled wire is almost wound and formed, control the external wire feeding device to stop feeding the flat enameled wire forward, and cut the flat enameled wire at the front end position of the wire outlet pipe 64 by the external cutting device. Wait for the multiple support plates 833 to continue rotating. After driving the cut flat enameled wire to complete the winding and forming work, control the servo motor 813 to stop working.

[0037] During this period, the flat enameled wire is always located in the guiding sliding hole at the lower end of the wire winding guiding plate 752 and moves uniformly to the right. It should be noted that roller brackets (not shown) are installed at the lower ends of the two vertical sections of the first C-shaped plate 72. The left and right roller brackets are respectively in rolling contact with the outer walls of the corresponding U-shaped extension plates 82, so as to achieve the effect that the first C-shaped plate 72 and the limiting roller 73 always maintain an equal distance from the corresponding U-shaped extension plates 82. During the rotation of the flat enameled wire driven by the plurality of support plates 833, the first C-shaped plate 72 will drive the limiting roller 73 to make a reciprocating up and down motion. The limiting roller 73 always keeps a small pressure against the outer wall of the flat enameled wire coil, ensuring that its bent inner wall is closely attached to the outer walls of the plurality of support plates 833. It should also be noted that under the action of the compression spring, when the plurality of support plates 833 drive the flat enameled wire to rotate, the higher side of the flat enameled wire is always protected and limited by the wire winding guiding plate 752 and a plurality of corresponding guiding sliding plates 836. And the flat enameled wire will be formed into a helix and slide successively between two adjacent left and right guiding sliding plates 836. The plurality of guiding sliding plates 836 will protect and limit the flat enameled wire to prevent it from being easily bent or twisted when subjected to tension or friction, resulting in an irregular shape of the coil or damage to the wire, and it is difficult to arrange the wire during the winding process, and the wire is prone to overlap or misalignment, thus affecting the uniformity and electrical performance of the coil.

[0038] After the winding is completed, first control the multiple plate-shaped electromagnets to start working. The multiple plate-shaped electromagnets will magnetically attract the trapezoidal slide plate 835 and the multiple guiding slide plates 836 respectively, causing them to retract into the corresponding installation chutes. Then, control the left and right screw rods two 842 to rotate synchronously and reversely through the double-shaft motor 841. The left and right screw rods two 842 drive the corresponding second electromagnetic suction plates 843 away from each other respectively. At this time, control the second electromagnetic suction plates 843 on both the left and right sides to start working. The second electromagnetic suction plate 843 on the left will tightly magnetically attract to the left L-shaped connecting plate 844. The second electromagnetic suction plate 843 on the left will drive the annular connecting plate 845 to move leftward through the left L-shaped connecting plate 844 until the annular connecting plate 845 drives the circular mounting table 81 to move leftward and return to its original position. During this period, as the second electromagnetic suction plate 843 on the left moves leftward, the right L-shaped connecting plate 844 will move rightward and contact the right L-shaped connecting plate 844, and tightly magnetically attract to the right L-shaped connecting plate 844. The right L-shaped connecting plate 844 will drive the rectangular connecting plate 832 to move rightward through the connecting slide rod 831. The rectangular connecting plate 832 will drive the corresponding support plates 833 to move rightward and return to their original positions through the multiple rectangular sliding strips 834. It should be noted that under the cooperative action of the multiple alignment magnets 814 on the right circular mounting table 81 and the multiple alignment magnets 814 on the inner wall of the annular plate 4, after the double-shaft motor 841 stops working, the angles of the left and right return extension plates 82 can also be guaranteed to be aligned, facilitating subsequent docking work. After the multiple support plates 833 lose the tensioning effect of the alignment slide rods 811, they will approach each other. And at this time, the left ends of the multiple support plates 833 are flush with the left ends of the return extension plate 82. The wound flat enameled coil will drop downward after losing the support of the multiple support plates 833 and will be received and conveyed by the peripheral conveying device for processing, thereby reducing the friction on the internal cavity of the formed flat enameled wire coil to achieve the effect of smoothly discharging the flat enameled coil. It should be noted that whenever the left circular mounting table 81 and the multiple support plates 833 both move to the appropriate positions, it is necessary to control the second electromagnetic suction plates 843 on both the left and right sides to stop working.

[0039] Then control the first electromagnetic suction plate 67 to stop working. At this time, under the action of the compression spring, the rectangular slide plate 753 will drive the winding guiding plate 752 to move to the left side position of the support slide rod 751 and return to its original position. Then, control the screw rod one 62 to rotate reversely through the peripheral motor. The screw rod one 62 will drive the wire outlet pipe 64 to move leftward at a constant speed through the sliding seat 63. The wire outlet pipe 64 will drive the return sleeve plate 66 to move leftward at a constant speed through the waist-shaped connecting plate 65. The return sleeve plate 66 will drive the first electromagnetic suction plate 67 to move leftward at a constant speed and return to its original position. Finally, control the telescopic end of the pneumatic push rod 52 to retract. The telescopic end of the pneumatic push rod 52 will drive the support cylinder 5 to rotate around the axis of the support shaft through the annular sleeve plate 51 until the support cylinder 5 becomes inclined and returns to its original position. Repeat all the above operations to repeat the automatic winding work of the flat enameled wire.

[0040] In summary, the present application has the following advantages: Advantage 1: In the present application, the winding part 8 adopts a method of supporting and winding the inner cavity of the flat enameled wire formed by winding. The left and right two lead screws 842 are controlled by the biaxial motor 841 to rotate synchronously. The left and right two lead screws 842 drive the corresponding electromagnetic suction plates 843 to approach each other respectively until the annular connecting plate 845 drives the circular mounting table 81 to move to the right to a suitable position. Multiple support plates 833 will drive the corresponding rectangular sliding strips 834 to move away from each other along the X-shaped chute, so that the outer walls of multiple support plates 833 are closely attached to the inner wall of the left receiving groove, thereby realizing the rapid docking and rapid tensioning of multiple support plates 833 and the left circular mounting table 81.

[0041] Advantage 2: After the outer wall of the limiting roller 73 is closely attached to multiple guiding sliding plates 836, the flat enameled wire to be wound is conveyed forward by an external wire feeding device. The flat enameled wire will penetrate into the sliding seat 63 and continue to be conveyed forward into the wire outlet pipe 64. At this time, the flat enameled wire will pass through the guiding sliding hole at the lower end of the winding guiding plate 752. Then the flat enameled wire will be conveyed forward along the outer walls of the guiding sliding plates 836 on the upper left side and the left end of the trapezoidal sliding plate 835 in sequence. Under the guiding action of the trapezoidal sliding plate 835, the front end of the flat enameled wire will be bent and deformed along the inclined surface end of the trapezoidal sliding plate 835 and embedded into the enameled wire embedding groove on the left return extension plate 82. Then control the external wire feeding device to stop conveying forward, thereby realizing the rapid connection between the front end of the flat enameled wire and the left return extension plate 82, which is convenient for subsequent winding work.

[0042] Advantage 3: After the barrel-shaped mounting plate 3 is driven by the servo motor 813 to rotate half a circle, then control the rotation speed of the barrel-shaped mounting plate 3 to gradually increase to a suitable speed for rapid winding, effectively improving the winding efficiency of the flat enameled wire. The right return extension plate 82 and the right circular mounting table 81 will rotate synchronously. At this time, the left return extension plate 82 will drive the flat enameled wire to rotate for winding work. At the same time, the lead screw 62 is controlled by an external motor to rotate, and the return sleeve plate 66 will drive the winding guiding plate 752 to move to the right at a constant speed through the electromagnetic suction plate 67, thereby realizing the effect that the flat enameled wire moves to the right at a constant speed for easy winding and forming. Whenever multiple support plates 833 drive the flat enameled wire to rotate one circle, the flat enameled wire will be formed into a spiral shape and slide into the space between two adjacent guiding sliding plates 836 on the left and right in sequence. Multiple guiding sliding plates 836 will protect and limit the flat enameled wire, avoiding it being easily bent or twisted when subjected to tension or friction, resulting in irregular coil shapes or wire damage, and also avoiding difficulties in wire arrangement during the winding process, where the wire is prone to overlap or misalignment, thus affecting the uniformity and electrical performance of the flat enameled coil.

[0043] Advantage 4: After the winding is completed, the left and right two lead screws 842 are controlled by the dual-axis motor 841 to rotate synchronously and reversely until the annular connecting plate 845 drives the circular mounting table 81 to move leftward to return to its original position. The rectangular connecting plate 832 will drive the corresponding support plate 833 to move rightward to return to its original position through a plurality of rectangular sliding strips 834. Under the cooperative action of the plurality of alignment magnets 814 on the right circular mounting table 81 and the plurality of alignment magnets 814 on the inner wall of the annular plate 4, after the dual-axis motor 841 stops working, the angles of the left and right return extension plates 82 can also be ensured to be aligned, facilitating subsequent docking work. After the plurality of support plates 833 lose the tensioning effect of the alignment slide rods 811, they will approach each other. At this time, the left ends of the plurality of support plates 833 are flush with the left ends of the return extension plates 82. After the flat enameled coil loses the support of the plurality of support plates 833, it will fall downward and be received and conveyed by an external conveying device for processing, thereby reducing the friction on the internal cavity of the formed enameled wire coil and achieving the effect of smoothly discharging the flat enameled coil.

[0044] Advantage 5: Control the electromagnetic suction plate 67 to stop working. At this time, under the action of the compression spring, the rectangular slide plate 753 will drive the winding guide plate 752 to move to the left side position of the support slide rod 751 to return to its original position, facilitating the subsequent magnetic suction docking work between the electromagnetic suction plate 67 and the winding guide plate 752.
