Description

Technical Field

[0001] The utility model belongs to the technical field of triangular three-dimensional iron core winding, in particular to a triangular three-dimensional iron core high-low voltage winding and foil winding and unwinding integrated machine. Background Art

[0002] When winding the triangular three-dimensional iron core, the high-voltage wire, low-voltage wire, copper foil, etc. are all discharged independently, and the copper foil needs to be used with a welding machine when discharging. That is, when winding the foil, the copper foil and the copper busbar are first welded by the welding machine, and then the normal foil winding operation is performed. Therefore, the high-voltage pay-off machine, low-voltage pay-off machine, copper foil pay-off machine and welding machine are usually placed separately in the winding workshop. In order to prevent mutual interference during discharge, the selective high-voltage pay-off machine, low-voltage pay-off machine, copper foil pay-off machine and welding machine are installed separately on the floor of the winding workshop, resulting in a large footprint and high cost. Moreover, with this arrangement, when choosing to wind a certain material, each pay-off machine needs to be moved to the corresponding position of the triangular three-dimensional iron core, which increases the winding time and has low efficiency.

[0003] The invention patent application with the publication number CN116959880A discloses a triangular three-dimensional iron core high and low voltage coil integrated winding machine, including a triangular three-dimensional iron core high and low voltage coil winding machine, an automatic welding vehicle, a combined unloading assembly and a low voltage wire rack arranged in sequence, and the unloading direction of each part is toward the triangular three-dimensional iron core high and low voltage coil winding machine. The combined unloading assembly includes a wire rack for high voltage coils, an insulating paper unloading shaft and a foil unloading rack. The device relatively concentrates the winding of high and low voltage coils and the unloading of copper foil, and the occupied area is relatively reduced; in this device, the combined unloading rack and the low voltage wire rack are placed front and back in an offset manner to avoid interference of the combined unloading rack when winding the low voltage wire. Therefore, there is no need to move each unloading machine to unload the high voltage wire, the low voltage wire or the copper foil, which solves the problem of low winding efficiency in traditional means.

[0004] However, in the above-mentioned invention patent, the automatic welding vehicle, the combined unloading assembly and the low-voltage wire rack are independent of each other and need to be carried separately during transportation, which is inconvenient to transport; and the high-voltage coil wire rack and the foil unloading rack are on the same horizontal line. When it is necessary to wind foil on the triangular three-dimensional iron core, the copper foil needs to bypass the high-voltage coil wire rack, which may affect the smooth unloading of the foil unloading rack. Although foil guide rollers are provided to guide the foil to bypass the high-voltage coil wire rack for transportation, it undoubtedly increases the production cost. Utility Model Content

[0044] It should be understood that the triangular three-dimensional winding core high and low voltage winding and foil winding and unwinding integrated machine described here is a preferred embodiment, which is only used to illustrate and explain the utility model, and does not constitute a limitation of the utility model.

[0045] The directional terms or positional relationships such as "left", "right", "front", and "back" described in the embodiments are based on the drawings in the specification of the utility model. Figure 1 and Figure 8 The orientation relationship is only for the convenience of describing the present invention and simplifying the description. It does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the content protected by the present invention.

[0046] Example 1

[0047] like Figures 1 to 10 As shown, this embodiment includes a winding platform 1, and a low-voltage pay-off machine 3, a high-voltage pay-off machine 4, a copper foil pay-off machine 5, an interlayer paper pay-off machine 6 and a welding machine 7 which are respectively slidably arranged on the winding platform 1. Each part is assembled into one device, which occupies a small area and has low cost. The discharge direction of the low-voltage pay-off machine 3, the high-voltage pay-off machine 4, the copper foil pay-off machine 5, and the interlayer paper pay-off machine 6 is the same, and the parts for placing the material rolls are all located on the same side. The low-voltage pay-off machine 3, the high-voltage pay-off machine 4, the copper foil pay-off machine 5, the interlayer paper pay-off machine 6 and the welding machine 7 can all slide separately. When a certain material is selected for winding, the remaining parts are moved to a position that does not affect the discharge.

[0048] like Figure 1 As shown, the winding platform 1 is a plate-like structure placed on the ground. The first box 8 and the copper foil feeder 5 are arranged on the winding platform 1 from left to right. The first box 8 is used to collect the low-voltage pay-off machine 3, the interlayer paper feeder 6 and the high-voltage pay-off machine 4. The first box 8 and the winding platform 1, and the copper foil feeder 5 and the winding platform 1 are all slidably connected through the guide rail assembly 2. The sliding direction of the first box 8 and the copper foil feeder 5 is along the width direction of the winding platform 1, that is, the direction perpendicular to the paper surface, which is also the front and rear direction. When the copper foil is selected to be wound on the triangular three-dimensional iron core, the first box 8 can be pushed backward to avoid affecting the foil winding efficiency.

[0049] In this embodiment, three sets of guide rail assemblies 2 are arranged between the first box 8 and the winding platform 1, and two sets of guide rail assemblies 2 are arranged between the copper foil unwinding machine 5 and the winding platform 1. The guide rail assembly 2 is a combination of a slider and a linear guide rail, which is a prior art and will not be described in detail here.

[0050] 1. Low voltage pay-off machine 3;

[0051] like Figure 2 , Figure 3As shown, the main structure of the low-voltage pay-off machine 3 adopts the existing technology, including a low-voltage pay-off rack 32 and a stabilizing mechanism 31. The low-voltage pay-off rack 32 is installed on the outside of the first box body 8. When in use, the low-voltage wire coil 34 is placed on the low-voltage material shaft 33 of the low-voltage pay-off rack 32 for pay-off; the stabilizing mechanism 31 is located on the inside of the first box body 8, and the appearance is neater. The stabilizing mechanism 31 includes a brake disc 301 and a pneumatic stopper 302. The pneumatic stopper 302 can exert a certain resistance on the brake disc 301, and can ensure the stable rotation of the low-pressure material shaft 33, so as to avoid the problem of low-voltage wire loosening due to the reduction of wire tension on the wire coil, which affects the winding quality. The specific structure will not be described in detail.

[0052] This embodiment has two improvements on the low-voltage pay-off machine 3. First, in order to ensure the compactness of the overall device, the number of low-voltage pay-off machines 3 is set to three, and they are installed at the upper position of the first box 8. The installation positions of the three low-voltage pay-off machines 3 are successively increased from left to right; second, in order not to affect the winding effect, the size of each low-voltage material shaft 33 is adapted to the size of the two low-voltage wire coils 34, that is, the length of the low-voltage material shaft 33 is increased, which is enough to place two low-voltage wire coils 34 at the same time. When in use, the six low-voltage wire coils 34 on the three low-voltage material shafts 33 are paid out at the same time to complete the low-voltage winding.

[0053] In this embodiment, the low-pressure material shaft 33 can play the role of guiding the low-voltage wire, and there is no need to install additional guide rollers.

[0054] 2. High voltage pay-off machine 4;

[0055] like Figure 1 , Figure 4 As shown, the main structure of the high-voltage wire-unwinding machine 4 adopts the existing technology, including a high-voltage unwinding rack 42 and a driving mechanism 41. The driving mechanism 41 includes a motor and a reducer, which are installed on the inner side of the first box body 8. The high-voltage unwinding rack 42 is installed on the outer side of the first box body 8. The output shaft of the driving mechanism 41 is fixedly connected to the high-voltage material shaft 43 in the high-voltage unwinding rack 42. The specific structure and working principle will not be described in detail.

[0056] The improvement of the high-voltage wire-releasing machine 4 in this embodiment is that the driving mechanism 41 of the high-voltage wire-releasing machine 4 is installed in the second box 11. In this embodiment, the second box 11 is a rectangular parallelepiped structure with a hollow interior. The second box 11 is sleeved in the first box 8 and is located at the lower right side of the first box 8. The bottom of the second box 11 is slidably connected to the winding platform 1 through two sets of guide rail assemblies 2, and the second box 11 can slide forward and backward independently inside the first box 8. Of course, the guide rail assembly 2 can also be set between the first box 8 and the second box 11, as long as the second box 11 can slide forward and backward along the first box 8.

[0057] When winding the high-voltage wire on the triangular three-dimensional core, the first box 8 can be slid backward and the second box 11 can be slid to the front to avoid the low-voltage pay-off machine 3 interfering with the operation of the high-voltage pay-off machine 4. This structure not only ensures the normal operation of the high-voltage pay-off and the low-voltage pay-off, but also makes the overall structure more compact, occupies a small area and has low cost.

[0058] 3. Copper foil unloading machine 5;

[0059] like Figure 1 , Figure 5 As shown, the copper foil unloading machine 5 is used to unload the copper foil. The copper foil unloading machine 5 is a prior art, comprising a third box 52, a copper foil unloading rack 53, a tensioning assembly and a power assembly. When in use, the copper foil roll is sleeved on four arc-shaped support plates 51 on the copper foil unloading rack 53, the copper foil roll is tightened by the tensioning device, and then the copper foil unloading rack 53 is driven by the power assembly to wind the copper foil on the triangular three-dimensional iron core. The specific structure and working principle of the copper foil unloading machine 5 are not described in detail in this embodiment.

[0060] The improvement of the copper foil unwinding machine 5 in this embodiment is that the third box body 52 is slidably connected to the winding platform 1 through two sets of guide rail assemblies 2. When winding copper foil on the triangular three-dimensional iron core, the first box body 8 and the second box body 11 can be slid backward, and the third box body 52 can be slid to the front to prevent the low-voltage unwinding machine 3 and the high-voltage unwinding machine 4 from interfering with the foil winding operation. At the same time, the installation of the foil guide roller is omitted, thereby reducing the production cost.

[0061] 4. Interlayer paper feeding machine 6;

[0062] like Figure 1 , Figure 2 As shown, when choosing to wind copper foil on the triangular three-dimensional iron core, it is necessary to ensure that there is a layer of insulating paper between two adjacent layers of copper foil. Therefore, the copper foil unwinding machine 5 is used in conjunction with the interlayer paper unwinding machine 6. The interlayer paper unwinding machine 6 is a prior art. Regarding its structure and working principle, this embodiment will not be described in detail. The improvement of this embodiment is that the interlayer paper unwinding machine 6 is installed below the low-voltage unwinding machine 3 on the first box body 8, and the interlayer paper material shaft 61 is located outside the first box body 8 and on the same side as the copper foil unwinding rack 53, so that the overall structure is more compact and the lateral space occupied is reduced.

[0063] 5. Waste paper material shaft 9;

[0064] The waste paper material shaft 9 adopts the existing technology and is installed on the third box body 52 to collect the waste paper generated when the copper foil is discharged. Figure 5 .

[0065] 6. Welding machine 7;

[0066] like Figure 1As shown, the left end of the winding platform 1 is the end close to the triangular three-dimensional iron core, and the unloading directions of the low-voltage unwinding machine 3, the high-voltage unwinding machine 4, the copper foil unwinding machine 5 and the interlayer paper unwinding machine 6 are all toward the left. When the foil is wound, the copper foil and the copper bar need to be welded by the welding machine 7 first, so the welding machine 7 is set at the end close to the triangular three-dimensional iron core, that is, the upper left corner of the first box 8.

[0067] The welding machine 7 includes a pushing assembly, a moving welding assembly and a lifting and pressing assembly;

[0068] like Figure 6 , Figure 8 As shown, the pushing assembly includes a support frame 701, which includes a vertical plate, a bottom plate and a side plate. The overall shape is a right triangle when viewed from the side. The bottom plate is fixed on the first box body 8, and there are two side plates. The two side plates are equivalent to reinforcing ribs to ensure a more stable structure. The pushing assembly also includes a first reduction motor 702 and a horizontal push plate 703. The first reduction motor 702 is fixed in the space formed by the vertical plate and the two side plates. The horizontal push plate 703 is slidably set on the support frame 701 through the guide rail assembly 2. The sliding direction of the horizontal push plate 703 is perpendicular to the discharge direction. The output shaft of the first reduction motor 702 is connected to a gear, and the gear is meshed with the rack on the lower edge of the horizontal push plate 703 to achieve forward and backward movement of the horizontal push plate 703. Figure 8 The middle rack is not shown. Of course, you can also choose to push the horizontal push plate 703 by hand to slide it back and forth.

[0069] like Figure 8 , Fig. 9 As shown, the mobile welding assembly includes a first mounting plate 704, a second reduction motor 705, a lead screw 706, a mobile frame 707 and a welding head 708. The welding head 708 is Figure 8 , Fig. 9 Not shown; the second reduction motor 705, the lead screw 706 and the movable frame 707 are all mounted on the first mounting plate 704, the second reduction motor 705 drives the lead screw 706 to rotate, the movable frame 707 moves linearly along the outer diameter of the lead screw 706, and the welding head 708 is fixed on the movable frame 707, so that it moves linearly with the movable frame 707.

[0070] Specifically, the lead screw 706 is fixed on the first mounting plate 704 through a lead screw fixing seat, the length direction of the lead screw 706 is along the front and rear directions, and the output shaft of the second reduction motor 705 is connected to the lead screw 706, so that the lead screw 706 can be driven to rotate.

[0071] like Figure 6As shown, the mobile frame 707 includes a vertical plate 709 and a horizontal plate 710 that are fixedly connected, and the two are in an "L"-shaped structure. The bottom end of the vertical plate 709 is fixedly connected to the lead screw nut. In order to limit the mobile frame 707 to make a linear motion and not rotate with the lead screw 706, a guide rail assembly 2 is also fixedly provided on the first mounting plate 704, wherein the linear guide rail is fixedly provided on the first mounting plate 704 and arranged side by side with the lead screw 706, and the length direction of the linear guide rail is parallel to the length direction of the lead screw 706, and a slider is slidably provided on the linear guide rail, and a horizontal connecting plate 711 is fixedly provided at the bottom end of the vertical plate 709, and the horizontal connecting plate 711 and the slider, and the horizontal connecting plate 711 and the lead screw 706 nut are all fixedly connected. When the lead screw 706 rotates, the lead screw 706 nut drives the movable frame 707 to rotate with the lead screw 706, but because the guide rail assembly 2 limits the movable frame 707, the movable frame 707 can only perform linear reciprocating motion along the axial direction of the lead screw 706 (i.e., the forward and backward directions).

[0072] The welding head 708 is installed on the horizontal plate 710 and is slidably arranged with the horizontal plate 710 to facilitate adjustment of the position of the welding head 708. The welding head 708 also slides axially along the lead screw 706 with the movable frame 707. The structure of the welding head 708 adopts the existing technology and will not be described in detail in this embodiment.

[0073] It should be noted that the first mounting plate 704 is fixedly connected to the horizontal push plate 703 through the bracket 10. Figure 6 , Figure 8 As shown, there are two brackets 10 , which are spaced apart along the length direction of the horizontal push plate 703 . The bracket 10 is an integrated structure, including a base plate 101 and a vertical plate 102 , wherein the base plate 101 is fixed on the horizontal push plate 703 , and the vertical plate 102 is fixedly connected to the first mounting plate 704 .

[0074] The lifting and pressing assembly includes a cylinder 712, a pressing plate and a second mounting plate 715;

[0075] like Figure 8 , Fig. 9 As shown, the main part of the second mounting plate 715 is parallel to the first mounting plate 704, and there is a certain gap between the second mounting plate 715 and the first mounting plate 704. The cylinder 712 and the pressure plate are arranged between the first mounting plate 704 and the second mounting plate 715. In order to fix the second mounting plate 715 to the first mounting plate 704, a fixing block 716 is arranged at the rear end of the second mounting plate 715. In this embodiment, the fixing block 716 and the second mounting plate 715 are an integrated structure, and the fixing block 716 is fixed to the first mounting plate 704 by a hexagon socket screw or other fasteners.

[0076] like Figure 6As shown, the pressing plate includes a first pressing plate 713 and a second pressing plate 714 which are fixedly connected. The fixed end (i.e., the right end) of the first pressing plate 713 is fixed in a hinged manner so that the first pressing plate 713 can rotate around the hinge point. The second pressing plate 714 is fixed at the free end (i.e., the left end) of the first pressing plate 713. The second pressing plate 714 is a long strip structure. Fig. 9 , and its length direction is set along the front and rear directions. When the first pressing plate 713 rotates with the hinge point as the rotation center, the free end of the first pressing plate 713 is tilted upward. After the copper bar and copper foil are placed directly under the second pressing plate 714, the first pressing plate 713 is rotated in the opposite direction so that the second pressing plate 714 presses the copper bar and copper foil. At this time, the welding head 708 is moved forward and backward to achieve welding.

[0077] Correspondingly, a support bar 723 is detachably provided on the second mounting plate 715 at a position corresponding to the second pressing plate 714. Figure 6 , Figure 8 , Fig. 9 As shown, in this embodiment, the support bar 723 is fixed to the left side surface of the second mounting plate 715 by means of hexagon socket screws. The effect of providing the support bar 723 is that before welding the copper foil and the copper busbar, it is often necessary to first hit the copper foil or the copper busbar with a hammer. In this embodiment, when welding, the copper foil and the copper busbar are located between the second pressure plate 714 and the support bar 723. Then, when hit with a hammer, the support bar 723 is the force-bearing surface. If damage occurs, the support bar 723 and the second pressure plate 714 can be replaced separately, and the maintenance cost is low.

[0078] The first pressing plate 713 is hingedly fixed at the right end in the following manner: Figure 8-10 As shown, the first pressing plate 713 is a rectangular parallelepiped structure, and an ear plate 717 is fixedly arranged at each of the two vertex positions on the right side of the first pressing plate 713. A pin hole is opened on the ear plate 717, and the pin 718 passes through the two pin holes in sequence, and a split pin is passed through the through hole on the pin 718 to prevent the pin 718 from withdrawing. Figure 8 , Fig. 9 The middle cotter pin is not shown. The pin shaft 718 is fixed to the first mounting plate 704 through the hanging plate 719. Specifically, the hanging plate 719 includes a vertical plate and a horizontal plate that are fixedly connected to each other, and the two are connected to form an "L" shape. The horizontal plate is provided with a limiting groove extending along the length direction of the first mounting plate 704, see Figure 6 , Figure 7Correspondingly, an extension plate 720 is provided on the side of the first mounting plate 704 facing the second mounting plate 715. The length of the extension plate 720 is the same as the length of the first mounting plate 704, and the width of the extension plate 720 is the same as the width of the limiting groove. The length described here refers to the distance in the front-to-back direction, and the width refers to the distance in the left-to-right direction. The extension plate 720 is embedded in the limiting groove on the horizontal plate, and then fixed by screws to fix the two. The ends of the pin shaft 718 pass through the vertical plate and are fixedly connected to the vertical plate. In this embodiment, both ends of the pin shaft 718 are fixedly connected to the extension plate 720 of the second mounting plate 715 through the hanging plate 719, so that the first pressing plate 713 can rotate around the pin shaft 718.

[0079] The cylinder 712 is fixed on the first mounting plate 704, and the cylinder rod is fixedly connected to the first pressing plate 713. Figure 6-7 , Fig.10 As shown, the first pressing plate 713 is provided with a through hole at the position corresponding to the cylinder rod. In this embodiment, the through hole is a waist-shaped hole 722. After the cylinder connector 721 passes through the first pressing plate 713 through the waist-shaped hole 722, it is fixedly connected to the cylinder rod. When the cylinder rod is extended and retracted up and down, the first pressing plate 713 is driven to rotate around the hinge point. When the first pressing plate 713 rotates, the waist-shaped hole 722 can leave room for the cylinder rod to move. Since the structure and working principle of the cylinder 712 are prior art, this embodiment will not be described in detail. Of course, the through hole can also be a circular hole or an elliptical hole, as long as the diameter of the through hole is greater than the diameter of the cylinder connector 721, and a certain space is left so that the cylinder connector 721 can move in the first pressing plate 713. In this embodiment, the cylinder 712 and the pressing plate are each provided with two groups, which are spaced along the length direction of the second mounting plate 715.

[0080] In order to ensure that the second pressing plate 714 can press the copper bar and the copper foil tightly during welding, the first pressing plate 713 is tilted in this embodiment. Figure 6-7 When the second pressing plate 714 contacts the second mounting plate 715, the height of the right end of the first pressing plate 713 is greater than the left end (i.e., the free end) of the first pressing plate 713. Compared with the horizontal straight state of the first pressing plate 713 when the second pressing plate 714 contacts the second mounting plate 715, the free end of the first pressing plate 713 can squeeze the second mounting plate 715, thereby pressing the copper busbar and the copper foil tighter.

[0081] Of course, the copper foil and the copper bar can also be pressed onto the second mounting plate 715 using only the first pressing plate 713 and the cylinder 712. Method 1: Use the free end of the first pressing plate 713 to press the copper bar and the copper foil onto the second mounting plate 715 and then weld them. Method 2: The cylinder rod can be directly fixed to the first pressing plate 713. The fixed end of the first pressing plate 713 does not adopt a hinged method. Then the cylinder rod will drive the first pressing plate 713 to rise and fall, and the copper foil and the copper bar can be pressed onto the second mounting plate 715. Method 3: The first pressing plate 713 is fixed to the first mounting plate 704 by a screw. The screw is fixedly connected to the first pressing plate 713. The screw is threadedly connected to the first mounting plate 704. When the screw is turned, the screw drives the first pressing plate 713 to move up and down.

[0082] It should be noted that a control box is provided on the welding machine 7 for controlling the movement of the first reduction motor 702, the second reduction motor 705 and the cylinder 712. Similarly, the high-voltage wire unwinding machine 4, the copper foil unwinding machine 5, etc. are also started or closed by the control switch. The structures of the control switch and the control box are all prior arts and will not be described in detail in this embodiment.

[0083] When using this embodiment, the high-voltage wire coil, the low-voltage wire coil 34, the interlayer paper coil and the copper foil coil are installed on their respective corresponding material shafts and wait for winding on the triangular three-dimensional iron core. Since the low-voltage pay-off machine 3, the high-voltage pay-off machine 4 or the copper foil pay-off machine 5 are independent pay-offs, this device can ensure that each pay-off is normal and does not affect each other. For example, when choosing to wind a high-voltage wire, push the first box 8 backward so that the high-voltage pay-off machine 4 is in a forward position to prevent the low-voltage pay-off machine 3 structure from interfering with the normal pay-off of the high-voltage pay-off machine 4. If copper foil is to be wound, first push the first box body 8 forward as a whole, start the first reduction motor 702, push the horizontal push plate 703 forward, use the mobile welding assembly and the lifting and pressing assembly to weld the copper bar and the copper foil, and then place the welded copper bar on the triangular three-dimensional iron core. At this time, the welding machine 7 is no longer used. The horizontal push plate 703 is moved backward by the first reduction motor 702 to prevent the welding machine 7 from extending forward and affecting the normal discharge of the copper foil. Finally, the first box body 8 and the second box body 11 are pushed backward to avoid interfering with the discharge of the copper foil.

[0084] The device integrates a low-voltage pay-off machine 3, a high-voltage pay-off machine 4, a copper foil pay-off machine 5, an interlayer paper pay-off machine 6 and a welding machine 7 on one device, and through reasonable layout, the overall structure is more compact, the floor space is small, and the cost is low; moreover, through reasonable setting of the installation position of each part, and the setting mode that each part can slide forward and backward independently, under the premise of compact structure, it can ensure that the discharge of each part can be carried out smoothly without affecting each other; in addition, the installation of all guide rollers is omitted, thereby reducing the production cost.

[0085] Example 2

[0086] like Fig.11 As shown, the structure of this embodiment is basically the same as that of embodiment 1, except that the number of low-voltage pay-off machines 3 is six, and accordingly, the length of the low-voltage material shaft 33 is shortened, and only one low-voltage wire coil 34 can be placed on each low-voltage material shaft 33, see Fig.12 Among the six low-voltage pay-off machines 3, four are installed above the first box body 8, and two are installed above the third box body 52. ​​The installation positions of the six low-voltage pay-off machines 3 are successively raised from left to right to ensure that the six low-voltage pay-off machines 3 can smoothly pay off the wires onto the triangular three-dimensional iron core at the same time; other structures are exactly the same as those in Example 1, and will not be elaborated in detail in this embodiment.
