Description

Technical Field

[0001] The invention relates to the technical field of wire coiling devices, and in particular to a wire coiling device for an enameled wire. Background Art

[0002] Enameled wire is a kind of wire, mainly used for winding of electrical equipment such as motors, transformers, electromagnets, inductors, etc. Its characteristic is that the outer layer of the conductive wire core is evenly coated with one or more layers of insulating varnish. After drying, this layer of insulating varnish forms a strong coating with good dielectric properties, which not only ensures the electrical isolation between the coils, but also allows the coils to be closely arranged in a certain space, thereby improving the efficiency and reliability of electrical equipment. The metal wire treated with enameling can be wound on the workbench as needed, and the enameled wire is neatly wound on the barrel to improve the insulation performance, effectively prevent short circuits, and enhance the mechanical strength of the wire, which is convenient for electrical equipment manufacturers to use.

[0003] A Chinese patent document with authorization announcement number CN113879907B discloses an enameled wire winding device and process, wherein the enameled wire winding device has two mounting frames for mounting a barrel, and a turntable is used to drive the mounting frames to rotate so that the mounting frames are alternately located on one side of a guide wheel, and the enameled wire is alternately wound. When the enameled wire on one barrel is full, the other barrel can be used to take over the winding of the enameled wire, thereby reducing the downtime of the enameled wire production line and improving the production efficiency of the enameled wire production line. In the above technical solution, when one barrel is fully wound with enameled wire, it is necessary to press the stop button of the controller to stop the second motor and the telescopic rod from working, and control the cylinder to contract so that the positioning cone block can be disengaged from the positioning groove. After the turntable rotates, the cylinder is controlled to extend so that the positioning cone block can be inserted into another positioning groove before the enameled wire can be wound on the other barrel. That is, during the alternation of the two barrels, the winding progress of the enameled wire needs to be temporarily set, and the replacement and alternation process is relatively cumbersome, which will interrupt the continuity of the production line, slow down the production speed, and affect the production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] Embodiment 1

[0027] like Figures 1 to 6 As shown, the winding device of the enameled wire of the present invention comprises a workbench 10, a winding assembly, a wire arrangement assembly and a threading assembly.

[0028] The workbench 10 is provided with a turntable 20 , which is in transmission connection with a first motor 210 . The first motor 210 is used for driving the turntable 20 to rotate, and the first motor 210 is installed on the workbench 10 .

[0029] The winding assembly includes two mounting heads 30 symmetrically arranged on the turntable 20 . The mounting heads 30 are used to mount the barrel 40 . The mounting heads 30 are transmission-connected to the second motor 310 . The second motor 310 is used to drive the mounting heads 30 to rotate.

[0030] The wire arranging assembly includes a wire arranging member 50 disposed on the turntable 20. The wire arranging member 50 is located on the symmetry axis of the two barrels 40. The wire arranging member 50 has a wire arranging gap 520 connecting the two barrels 40. The wire arranging gap 520 extends in the vertical direction. The wire arranging member 50 is transmission-connected to the first linear drive member 510. The first linear drive member 510 is used to drive the wire arranging member 50 to move along the length direction of the barrel 40.

[0031] The threading assembly includes a sliding block 60 slidably connected to the barrel 40, with a threading gap 620 between the sliding block 60 and the barrel 40, and the sliding block 60 is transmission-connected to a second linear drive member 610, which is used to drive the sliding block 60 to slide relative to the barrel 40 to adjust the threading gap 620.

[0032] The first linear driving member 510 and the second linear driving member 610 are any one of an electric push rod, a hydraulic cylinder and a pneumatic cylinder.

[0033] So, like Figures 1 to 6 As shown, and refer to Figure 1 In the orientation shown in FIG, two mounting heads 30 for mounting the barrel 40 are arranged on the left and right sides of the turntable 20, and the enameled wire passes through the threading gap 620 and the wire arrangement member 50 of the left barrel 40, and then passes through the threading gap 620 of the right barrel 40. The right barrel 40 starts to rotate under the drive of the second motor 310, and the enameled wire is wound on the right barrel 40 under the rotation of the right barrel 40;

[0034] During winding, a threading gap 620 is left between the left barrel 40 and the sliding block 60 for winding the enameled wire to keep it straight and smooth, reduce the occurrence of entanglement and dislocation, and improve the quality and reliability of the coil. The right barrel 40 and the sliding block 60 clamp the end of the enameled wire; the wire arrangement member 50 reciprocates along the length direction of the barrel 40 under the drive of the first linear drive member 510, guides the winding position of the enameled wire on the barrel 40, so that the winding position of the enameled wire is accurate and neat, and the uniformity and stability of the coil are improved;

[0035] When the winding of the right barrel 40 is about to be completed, the left barrel 40 starts to rotate under the drive of the second motor 310, so that the enameled wire between the two barrels 40 is disconnected, the winding of the right barrel 40 is completed, and the rotation is stopped under the control of the second motor 310, the barrel 40 on the right side that is fully wound with enameled wire is removed, and a new barrel 40 is installed on the installation head 30;

[0036] The first motor 210 drives the turntable 20 to rotate 180 degrees to replace the positions of the two barrels 40. After the replacement, the rotating barrel 40 is located on the right side of the turntable 20, and the stopped barrel 40 is located on the left side of the turntable 20. During the rotation of the turntable 20, the enameled wire automatically enters the threading gap 620 and the wire arrangement member 50 of the new barrel 40, and the above process is repeated, thereby realizing automatic barrel replacement of the barrel 40 and ensuring that the winding progress of the enameled wire continues during the barrel replacement, maintaining the continuity of the production line, and improving the production speed and efficiency.

[0037] It is to be supplemented here that the next time the turntable 20 rotates to replace the positions of the two barrels 40, the direction of rotation of the turntable 20 should be opposite to the last time, so as to prevent the enameled wire from being entangled on the wire arrangement member 50 or the barrel 40, and to prevent the enameled wire from being misplaced or incorrectly stacked.

[0038] like Figures 2 to 5 As shown, the barrel 40 includes a barrel 410 and end plates 420 fixed at both ends of the barrel 410. The barrel 410 is cylindrical with a notch. The notch of the barrel 410 is used to accommodate the sliding block 60. The sliding block 60 includes an arcuate side, a horizontal side, a vertical side and an inclined side. The arcuate side can be connected with the outer peripheral side of the barrel 410 to avoid the sliding block 60 protruding relative to the surface of the barrel 410 during the winding process and affecting the uniformity of the coil. The inclined side and the vertical side are respectively located at both ends of the length direction of the arcuate side. The inclined side has an inclined groove 630 that slides with the barrel 410, thereby realizing the sliding connection between the barrel 410 and the sliding block 60. A vertical gap can be formed between the vertical side and the end plate 420. The horizontal side is opposite to the arcuate side and can form a horizontal gap with the barrel 410. The horizontal gap is connected to the vertical gap to form a threading gap 620. The vertical gap is connected to the outside world and is used to guide the enameled wire into the horizontal gap during the rotation of the turntable 20.

[0039] The second linear drive member 610 is mounted on the turntable 20. The output end of the second linear drive member 610 is fixed with a mounting plate 6110 for mounting the second motor 310. The output end of the second motor 310 is fixed with an inner disk body 70. The mounting head 30 includes an outer disk body 320 and a square shaft 330 that are fixedly connected. The square shaft 330 is used to mount the barrel 40 so as to realize synchronous rotation of the barrel 40 and the mounting head 30. The outer disk body 320 is rotatably connected to the turntable 20. The outer disk body 320 has first vertical grooves 320 that are interconnected. 210 and a second vertical groove 3220, the first vertical groove 3210 is slidably connected with the first shaft 80, the first shaft 80 is used to install the sliding block 60, the second vertical groove 3220 is slidably connected with the inner disk body 70, a limit block 710 is fixed below the inner disk body 70, the limit block 710 is located in the first vertical groove 3210, and is used to push the first shaft 80, and at the same time realize the synchronous rotation of the outer disk body 320 with the inner disk body 70, when the inner disk body 70 moves to the top of the second vertical groove 3220, it is coaxial with the barrel 40.

[0040] In this way, before installing the barrel 40, the second linear drive member 610 drives the mounting plate 6110 and the inner disk body 70 to move in the vertical direction, so that the sliding block 60 is away from the barrel body 410 to form a threading gap 620, and at the same time, the inner disk body 70 pushes the second vertical slot 3220 to rotate, and the second vertical slot 3220 is adjusted to a vertical state, that is, the position of the outer disk body 320 is calibrated, thereby ensuring that after the barrel 40 is installed, the horizontal side of the sliding block 60 remains in a horizontal state; after the barrel 40 is installed, during the rotation of the turntable 20, the enameled wire enters the water through the vertical gap of the barrel 40. During the winding of the other barrel 40, the second linear drive member 610 can drive the mounting plate 6110 and the inner disk 70 to move in the vertical direction, so that the threading gap 620 is reduced, thereby ensuring the wire-winding effect; before starting to wind, the second linear drive member 610 drives the mounting plate 6110 and the inner disk 70 to continue to move in the vertical direction, so that the sliding block 60 is close to the barrel 410 and cooperates with the notch of the barrel 410 to clamp and fix the wire end of the enameled wire until the inner disk 70 is coaxial with the barrel 40, and the second motor 310 is started, and the barrel 40 starts to rotate for winding.

[0041] The outer disk body 320 also has inner grooves 3230 distributed along the vertical direction, and the first shaft 80 has a limit plate 810 slidably matched with the inner grooves 3230 to prevent the first shaft 80 from being separated from the outer disk body 320 .

[0042] The turntable 20 has two limiting rods 220 that are arranged opposite to each other. The limiting rods 220 have limiting grooves distributed along the vertical direction for installing the mounting plate 6110 to ensure the stability of the mounting plate 6110 when moving along the vertical direction.

[0043] like Figure 1 and Figure 6As shown, the wire arrangement member 50 includes a head 530 and two rod bodies 540 fixedly connected to the head 530, and a wire arrangement gap 520 is formed between the two rod bodies 540. The ends of the two rod bodies 540 facing away from the head 530 have relatively arranged inclined surfaces to form a V-shaped opening, which can more effectively guide the enameled wire into the wire arrangement gap 520.

[0044] Embodiment 2

[0045] like Figure 3 As shown, compared with the first embodiment, the inner side surface of the end plate 420 of this embodiment is evenly distributed along its circumference with a plurality of one-way clips 4210 for clamping the enameled wire, and the open ends of the plurality of one-way clips 4210 face the same direction. In the first embodiment, when the enameled wire between the two barrels 40 is disconnected, the enameled wire on the barrel 40 that is fully wound with the enameled wire may be scattered. For this reason, the present embodiment adds a one-way clip 4210 for fixing the wire end after the enameled wire is disconnected to prevent the enameled wire on the barrel 40 that is fully wound with the enameled wire from being scattered. It is hereby supplemented that the rotation direction of the barrel 40 during winding should be opposite to the direction of the open end of the one-way clip 4210 to prevent the enameled wire from being stuck in the one-way clip 4210 during the winding process.

[0046] like Figure 6 As shown, a scissors 910 is provided at the connection between the two rod bodies 540 and the head 530 for cutting the enameled wire, so that the disconnection process of the enameled wire is more stable.

[0047] like Figure 1 , Figure 6 and Figure 7 As shown, a cutting assembly is provided at one end of the two rod bodies 540 away from the head 530, and the rod body 540 has a receiving groove 5410 for receiving the cutting assembly, and the cutting assembly includes a rotating rod 920, one end of the rotating rod 920 is rotatably connected to one receiving groove 5410, and an elastic member 940 is provided between the rotating rod 920 and the receiving groove 5410, and the other end of the rotating rod 920 extends into another receiving groove 5410, and the rotating rod 920 is fixed with a cutter 930 facing the head 530 at the wire arrangement gap 520. Thus, when the enameled wire moves to the open end of the wire arrangement member 50, the cutter 930 can cut the enameled wire, and due to the arrangement of the rotating rod 920 and the elastic member 940, the enameled wire is not affected from entering the wire arrangement member 50.

[0048] The elastic member 940 is a spring sheet, which has good elasticity.

[0049] So, like Figures 1 to 7 As shown, and refer to Figure 1In the position shown in , when the winding of the right barrel 40 is about to be completed, the right barrel 40 rotates in the opposite direction under the drive of the second motor 310, so that the enameled wire is stuck in the one-way clip 4210, and the left barrel 40 starts to rotate under the drive of the second motor 310. Take the case where the barrel 40 rotates counterclockwise when winding the wire, and the turntable 20 rotates until the opening of the wire arrangement member 50 faces downward as an example, at this time, the right barrel 40 rotates clockwise, and the left barrel 40 starts to rotate counterclockwise, and the enameled wire between the two barrels 40 will move upward and can be cut by the scissors 910. After the turntable 20 rotates 180 degrees next time, the opening of the wire arrangement member 50 faces upward, and when the enameled wire moves upward and needs to be cut, it can be cut by the cutter 930.

[0050] The rest of the content of this embodiment can refer to the first embodiment and will not be described in detail here.
