Description

Technical Field

[0001] The present application relates to the field of transformer manufacturing equipment, and in particular to a stripping mechanism and a wire feeding device. Background Art

[0002] A transformer is an electrical component that is mainly used for voltage conversion, current conversion, isolation, and impedance matching. Specifically, the basic working principle of a transformer is to use the principle of electromagnetic induction. Through the magnetic coupling between the two coils, when the primary coil is energized, a changing magnetic field is generated. The magnetic field is transmitted to the secondary coil through the iron core, thereby generating an induced electromotive force in the secondary coil to achieve voltage conversion. In general, the transformer is a very important electrical device that is widely used in power systems, electronic equipment, and communication systems, and plays a key role in the transmission, configuration, and conversion of electrical energy.

[0003] Usually, the core components of a transformer are windings and iron cores, wherein the windings mainly include a skeleton and a coil wound on the skeleton, the ends of the coils are wound on the pins of the skeleton, and conduction is achieved through the pins. Based on this, the winding action is usually implemented by a winding device. Here, the inventor has invented an automated device for winding, such as the Chinese invention patent with announcement number CN114512331A, which discloses an integrated transformer bushing winding and rubber coating device, which mainly includes a skeleton rotating mechanism, a bushing threading mechanism, a coil front foot winding mechanism, a coil rear foot winding mechanism, and a rubber coating mechanism. Under the mutual cooperation of each mechanism, the coil can be sent out, one end of the coil can be hung on one of the pins, and then the coil can be wound on the skeleton, and the coil can be cut off, and finally the other end of the coil can be hung on another pin of the skeleton, so as to realize the automated processing of the winding, and the production efficiency of the winding can be greatly improved.

[0004] With regard to the above-mentioned related technologies, with the upgrading of transformer structures, more and more transformer products have higher requirements for insulation functions. For example, the coil can also use materials such as enameled wire, which reduces the breakdown probability of the winding by setting an enameled layer on the outside of the wire; further, in the process of winding this type of wire, in order to ensure that the conductor can conduct the pins of the skeleton, before winding, it is necessary to peel the two ends of the wire separately. However, because the movement of the wire in the above-mentioned automated winding equipment is continuous, in the current conventional stripping process, semi-automatic equipment is usually used to strip the two ends of the coil separately. This will cause the processing action to be unable to be efficiently connected in the winding equipment with a high degree of automation, and thus cannot meet the continuous production needs of the coil in the production equipment. At present, there is still a lack of a solution that can strip the coil during the continuous delivery of the wire, so it needs further optimization and improvement. Utility Model Content

[0005] In order to overcome the problem of peeling of the enamel coating of the wire during continuous movement, the present application provides a stripping mechanism and a wire feeding device.

[0014] By adopting the above technical solution, the extension frame plays a role in adjusting the placement of the wire cutter. At this time, by extending the wire cutter between the wire stripping assembly and the guide, when the guide enters the wire stripping assembly for the first time, one end of the wire can be stripped first. At this time, the wire can be wound on the skeleton until the winding action is completed. The wire cutter then cuts the wire. At this time, the wire stripping assembly can strip the enameled wire of the end of the wire that has just been cut. The structure is reasonable and the action is smooth, which is well adapted to the continuous operation requirements of the wire.

[0045] The following is combined with Figure 1-6 This application is described in further detail.

[0046] Embodiment 1:

[0047] An embodiment of the present application discloses a wire feeding device, which can be installed in a winding device.

[0048] Reference Figure 1 The wire feeding device includes a wire feeding mechanism 1, a traction mechanism 2 and a stripping mechanism, wherein the wire feeding mechanism 1 and the traction mechanism 2 are respectively located on opposite sides of the stripping mechanism, the wire feeding mechanism 1 is used to continuously feed the wire straightly, and the traction mechanism 2 is used to pull the wire to the skeleton for winding. During this process, the traction mechanism 2 drives the wire to pass through the stripping mechanism, and the stripping mechanism is mainly used to remove the enameled layer at the end of the wire; specifically, in the process of the wire passing through the stripping mechanism, the stripping mechanism first strips off the enameled layer at one end of the wire, and then cuts the wire to segment the wire, and the segmented wire obtains the other end of the free wire; then, the stripping mechanism strips the other end of the cut wire, so that the two ends of the wire are stripped during the continuous feeding process, and the movement continuity of the coil in the subsequent winding process is improved.

[0049] Based on this, refer to Figure 2 The wire feeding mechanism 1 includes an output element 11 and a roller group 12. The output element 11 is fixedly mounted on a frame. The output element 11 is a type of element that can output rotational power, such as a motor, a hydraulic motor or a pneumatic motor. In this embodiment, a motor is used as a power output source. In addition, the roller group 12 includes a pair of roller elements that are interconnected, wherein the roller element includes a gear 121, a roller 122 and a rotating shaft 123 fixedly installed on the roller 122, the rotating shaft 123 can be rotatably installed on the frame, the gear 121 is fixedly installed in the rotating shaft 123, and two gears 121 between a stack of roller elements are meshed with each other; at the same time, the output shaft of the output element 11 is connected to one of the rotating shafts 123 through a coupling, at this time, the torque generated by the output element 11 can be output to the rotating shaft 123, the rotating shaft 123 drives the roller 122 arranged thereon to rotate, and under the mutual meshing of the gears 121, the other set of rotating shafts 123 and the roller 122 rotate synchronously.

[0050] Under the action of the synchronous rotation of the two groups of roller elements, the wire is placed between the two rollers 122. At this time, the wire can be wrapped on the roller group 12. Under the action of friction, since the two sides of the wire are subjected to balanced friction force, the two rollers 122 clamp the wire and send it out. The sending action is stable and reliable and not easy to deviate.

[0051] Reference Figure 3, in order to achieve the traction of the wire. The traction mechanism 2 specifically includes a driving element (not shown in the figure) and a clamping element 21, wherein the driving element is used to output a three-dimensional displacement to drive the clamping element 21 to move flexibly. Specifically, the driving element can usually adopt an xyz three-axis linear module 41, and the clamping element 21 is fixedly installed on the driving element, and the clamping element 21 can be driven to move by the driving element; the main function of the clamping element 21 is to clamp the wire. In this embodiment, the clamping element 21 is selected as a clamping cylinder, and the wire is stably clamped by the clamping cylinder. In other embodiments, electric clamps or hydraulic clamps can also be used instead of clamping cylinders. Elements that can realize the clamping function can be tried and selected, and no specific restrictions are made here.

[0052] At this time, under the clamping action of the clamping element 21, the driving element cooperates to pull the wire to drive the wire to pass through the stripping mechanism.

[0053] To this end, in order to realize the simultaneous peeling and cutting process during the straight delivery of the wire, this embodiment also discloses a peeling mechanism. Figure 3 and Figure 4 The stripping mechanism includes a guide 3, a displacement assembly 4, a wire cutting assembly 5 and a wire stripping assembly 6. The wire sent out by the wire feeding mechanism 1 first passes through the guide 3, which is mainly used to guide and position the wire so that the wire can be straightly moved to the wire stripping assembly 6 for stripping.

[0054] Specifically, the guide member 3 includes a seat body 31 and a guide tube 32. The seat body 31 is a block structure in this embodiment. The seat body 31 can be directly fixedly mounted on the frame and is opposite to the position between the two rollers 122. In addition, a through hole is provided in the middle of the seat body 31, and the guide tube 32 is passed through the through hole and fixedly mounted on the seat body 31. At this time, a guide channel is formed inside the guide tube 32, and the guide channel is used for the wire body to pass through. Under the guidance of the guide tube 32, the wire body can be driven to be accurately and straightly transferred to the wire cutting assembly 5 and the wire stripping assembly 6.

[0055] Continue to refer to Figure 3 and Figure 4 , the wire cutting assembly 5 and the wire stripping assembly 6 are respectively arranged at the displacement assembly 4, and the displacement assembly 4 drives the wire cutting assembly 5 and the wire stripping assembly 6 to move. In this embodiment, the stripping of the enamel layer is achieved by vertical punching followed by axial displacement. Specifically, to achieve the axial displacement action, first, the displacement assembly 4 is arranged on the frame and adjacent to the guide 3; the displacement assembly 4 specifically includes a linear module 41, a slide rail 42 and a slider 43. In this embodiment, the linear module 41 uses a screw-type stepping motor as the linear module 41, and the motor is fixedly installed on the frame, and the screw is parallel to the axial direction of the wire feeding.

[0056] In addition, the slide rail 42 is fixedly installed on the frame and is located between the guide member and the linear module 41. The slide rail 42 and the screw rod are parallel to each other, and the slider 43 is slidably installed on the slide rail 42. The slider 43 and the screw rod are connected to each other by setting a connecting arm. At this time, starting the screw rod can push the connecting arm to move, thereby driving the slider 43 to move back and forth on the slide rail 42. At this time, the wire cutting assembly 5 and the wire stripping assembly 6 are respectively arranged on the slider 43, and the slider 43 can drive the wire cutting assembly 5 and the wire stripping assembly 6 to reciprocate along the axial direction of the wire.

[0057] At the same time, refer to Figure 4 The wire stripping assembly 6 includes a power element 61, a first blade head 62 and a second blade head 63. The power element 61 is used to drive the first blade head 62 and the second blade head 63 to move closer to or farther from each other to achieve a punching action. Specifically, in this embodiment, the power element 61 uses a pneumatic clamp. In other embodiments, components such as a telescopic cylinder, a hydraulic clamp or an electric clamp may also be tried. The specific structure of the power element 61 is not limited here. Any component that can achieve a punching action may be tried and should be included in the protection scope of the power element 61.

[0058] In addition, the first blade head 62 and the second blade head 63 have similar structures, both of which are blade structures. The blades of the first blade head 62 and the second blade head 63 face each other, and both have blades at the positions facing each other. The wire passes between the first blade head 62 and the second blade head 63 under the action of the traction assembly. When the power element 61 drives the first blade head 62 and the second blade head 63 to approach each other, the first blade head 62 and the second blade head 63 can vertically punch the enameled layer from the opposite sides of the wire. After the enameled layer is punched, the enameled layer is peeled off along the axial direction of the wire under the drive of the slider 43 mentioned above.

[0059] Furthermore, when punching the enamel layer, if a flat blade structure is used, the punching part of the enamel layer in the circumferential direction may be incomplete, affecting the stripping effect. Based on this, punching recesses 64 are respectively set at the relative positions of the first blade head 62 and the second blade head 63. In this embodiment, the punching recesses 64 are V-shaped recessed structures. When the first blade head 62 and the second blade head 63 are gathered together, the two punching recesses 64 form a closed punching profile, and the circumference of the enamel layer is punched through the closed blade. Here, the concave part of the blade can play a role of avoidance, and then the more parts of the circumferential side of the enamel layer are covered and punched, and the punching effect is improved.

[0060] Continue to refer to Figure 4After one end of the wire is stripped, the wire is then cut into segments by the wire cutting assembly 5, and then the other end of the wire is stripped. To achieve the wire cutting action, the wire cutting assembly 5 includes an extension frame 51 and a wire cutter 52. The extension frame 51 is fixedly mounted on the slider 43 of the displacement assembly 4, and the wire cutter 52 is fixedly mounted on the extension frame 51. The wire cutter 52 is an electric scissors in this embodiment. The extension frame 51 extends the wire cutter 52 to between the wire stripping assembly 6 and the guide 3. At this time, driven by the slider 43, the wire can be cut at a suitable position, so that the wire stripping mechanism can subsequently strip the other end of the wire.

[0061] It should be noted that, in other embodiments, the punching recess 64 may also be semi-elliptical, semi-circular, or U-shaped, and any structure that can perform multi-directional punching of the wire circumference should be included in the protection range of the punching recess 64.

[0062] The implementation principle of Example 1 of the present application is: under the drive of the traction mechanism 2, the wire sent out through the wire feeding mechanism 1 is pulled to the skeleton for winding, and the stripping mechanism is used to perform end stripping processing on the continuously fed wire between the traction mechanism 2 and the wire feeding mechanism 1; specifically, firstly, one end of the wire is stripped by vertical punching and axial displacement, and then the wire is cut into sections after the winding action is completed, and the stripping operation is performed at the other end of the wire, and the wire stripping processing is realized under the continuous wire feeding state, and the overall processing efficiency of the winding equipment is significantly improved.

[0063] Embodiment 2:

[0064] Reference Figure 5 and Figure 6 In actual production, the winding equipment has the demand for multi-station synchronous winding, so as to synchronously wind multiple windings. Based on this, in this embodiment, the roller group 12 can also be set to multiple groups, such as two groups, three groups, four groups, etc. This embodiment uses two groups as an example, and the two groups of roller groups 12 are arranged side by side on the frame.

[0065] When two groups are set up, one roller element can be shared between the two groups of roller groups 12, that is, there are three roller elements, and the three roller elements are arranged side by side. The gear 121 of the roller element located in the middle is respectively meshed with the other two gears 121, and the output element 11 is fixedly connected to the rotating shaft 123 of the roller element located in the middle; at this time, the output element 11 can be controlled to output positive and reverse torques respectively, thereby controlling the two groups of roller elements to respectively deliver different wires.

[0066] At this time, the number of traction mechanisms 2 and stripping mechanisms is adapted to the number of wires fed out. For example, in the present embodiment, the traction mechanism 2 is provided in two groups, and they are respectively opposite to the two roller groups 12, so as to pull the two wires. In addition, the stripping mechanism is also provided in two groups, which are respectively arranged at the two strands of wires. At this time, the two strands of wires can be stripped separately, so as to realize multi-station stripping action, which can more efficiently adapt to the multi-station winding requirements of the winding equipment.

[0067] In addition, when the number of roller groups 12 is greater than two groups, the output element 11 is connected to the multiple roller groups 12 through linkage elements. Specifically, the linkage elements mainly include belts and pulleys. The number of pulleys is consistent with the number of roller groups 12 plus the output element 11. Several pulleys are respectively fixed on the rotating shaft 123 of the roller group 12 and installed on the output shaft of the output element 11. At this time, the belt is wrapped around several pulleys, the output element 11 outputs power, and the power is transmitted to each roller group 12 through the linkage components. Each roller group 12 can deliver the wire separately. The number of settings of the traction mechanism 2 and the stripping mechanism is adaptively set to meet the needs of multi-station wire stripping processing.

[0068] The implementation principle of Example 2 of the present application is: by setting a linkage element in the wire feeding mechanism 1 and setting the roller group 12 into multiple groups, it is possible to feed out multiple strands of wires. At the same time, the traction mechanism 2 and the stripping mechanism are adapted to be set, so that multi-station stripping operations can be realized in the winding equipment, and the stripping and winding efficiency of the product is further improved.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
