[0002] In current axial motor paper-gathering devices, the space of the slotted wedge inserted on the stator of the axial motor is required for paper-gathering.

Summary of the Invention

[0012] In one specific implementation, the guide surfaces of the two sheet metal pieces are mutually mating curved surfaces.

[0013] In one specific implementation, a slot wedge insertion mechanism is further included, which is slidably connected to the base; the slot wedge insertion mechanism is located on the side of the pressure plate opposite to the paper-binding assembly; The sliding direction of the slot wedge insertion mechanism is along the first direction, and it can press against the outer wall of the motor stator.

[0014] In one specific implementation, a second elastic element is further included, one end of which abuts against the base and the other end of which abuts against the slotted wedge insertion mechanism.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0020] To facilitate understanding of the axial motor paper-binding device provided in this application embodiment, its application scenario is first described. The axial motor paper-binding device provided in this application embodiment is used to bind insulating paper on an axial motor. Current axial motor paper-binding devices require utilizing the slot space of the wedge inserted into the stator of the axial motor for paper binding. This necessitates matching the wedge slot with the mechanism of the axial motor paper-binding device, resulting in a relatively large slot that affects the magnetic flux of the motor stator. Therefore, this application embodiment provides an axial motor paper-binding device to improve the paper-binding effect. A detailed description is provided below with reference to specific drawings and embodiments.

[0021] To facilitate understanding, the motor stator provided in the embodiments of this application will be introduced first, with reference to... Figure 1 and Figure 2 As shown, Figure 1 A reference diagram showing the use of the axial motor paper-binding device (hereinafter referred to as paper-binding device 100) provided in an embodiment of this application is shown. Figure 2A side view of the paper-binding device in use is shown. During installation, copper wire needs to be wound around the end of the motor stator 200, and electrical insulation between the copper wire and the motor stator 200 is required. Therefore, insulating paper needs to be inserted into the paper slots 210 at the end of the motor stator 200 to wrap the copper wire. Specifically, multiple paper slots 210 are provided at the end of the motor stator 200. U-shaped insulating paper is placed in the paper slots 210, with one end of the insulating paper protruding from the outer wall of the motor stator 200. After the copper wire is inserted, the insulating paper is bound together by the paper-binding device 100, that is, the two opposite edges of the U-shaped insulating paper are folded and overlapped to form a cylindrical structure. After binding, a slot wedge needs to be inserted to keep the insulating paper in a bound state. Specifically, the two opposite side walls of the paper insertion slot 210 are respectively provided with slot bodies 220. After the paper is joined, the slot wedge is inserted into the slot body 220 to fix the slot wedge and keep the insulating paper in the joined state through the slot wedge.

[0022] For ease of understanding, a first direction, a second direction, and a third direction are defined. The first direction and the second direction are perpendicular to each other. The first direction is the length direction of the insulating paper, the second direction is the width direction of the insulating paper, and the third direction is the height direction of the insulating paper.

[0023] The paper-binding device 100 provided in this application mainly includes a base 140, a paper-binding assembly 110, and a pressing plate 120. The base 140 serves as an integral support mechanism, supporting the paper-binding assembly 110 and the pressing plate. In use, the base 140 can drive the paper-binding assembly 110 and the pressing plate 120 to move along a first direction, thereby driving the paper-binding assembly 110 to bind the insulating paper. Furthermore, the base 140 can also drive the pressing plate 120 to press down the bound insulating paper, thus maintaining the bound state of the insulating paper. The paper-binding device 100 provided in this application will be described in detail below with reference to the specific accompanying drawings.

[0024] The paper-binding assembly 110 and the pressing plate are both mounted on the base 140, so that their movement is driven by the base 140, such as... Figure 3 As shown, the base 140 is driven by an external drive mechanism 300 to move back and forth along a first direction. In the configuration, the paper-binding assembly 110 and the pressure plate are spaced apart along the first direction, with the paper-binding assembly 110 positioned closer to the motor stator 200 than the pressure plate. This allows the base 140 to first bind the insulating paper together via the paper-binding assembly 110, and then maintain the bound state of the insulating paper via the pressure plate 120, when driving the paper-binding assembly 110 and the pressure plate 120.

[0025] like Figure 4As shown, the paper-fitting assembly 110 includes two paper-fitting sheets 111, which are arranged along a second direction. The two paper-fitting sheets 111 are provided with guide surfaces on opposite sides for folding the two edges of the U-shaped insulating paper. The two guide surfaces are mutually cooperating guide surfaces, which can guide the two edges of the insulating paper to overlap when the paper-fitting assembly 110 moves along a first direction.

[0026] The two sheet metal pieces 111 described above can also open and close in the second direction to facilitate clamping the ends of the insulating paper exposed outside the outer wall of the motor stator 200 before the paper is closed. For example, as shown... Figure 4 As shown, when the two sheet metal panels 111 are opened or closed to the first state, the distance between the two sheet metal panels 111 is greater than the width of the insulating paper along the second direction; as Figure 5 As shown, when the two sheet metal panels 111 are opened and closed to the second state, along the second direction, the distance between the two sheet metal panels 111 is less than the width of the insulating paper, and the bonding... Figure 1 and Figure 2 In the illustrated use state of the paper-jointing device 100, the distance between the two opposite sides of the two paper-jointing plates 111 is less than the width of the paper insertion slot 210 on the motor stator 200. Specifically, when paper joining is required, the two paper-jointing plates 111 are initially in a first state, and the paper-jointing assembly 110 is moved along a first direction to the outside of the motor stator 200 by the base 140. At this time, the portion of the insulating paper exposed on the outer wall of the motor stator 200 is located between the two paper-jointing plates 111. Afterward, the two paper-jointing plates 111 close to a second state, and the two paper-jointing plates 111 push the two opposite edges of the insulating paper exposed at one end of the motor stator 200 to begin overlapping. The maximum width of the two paper-jointing plates 111 after closing is less than the width of the paper insertion slot 210, so that the paper-jointing assembly 110 can be inserted into the paper insertion slot 210 and joined with the insulating paper by the action of the base 140.

[0027] The paper-joining assembly 110 provided in this application embodiment further includes a first driving mechanism 160, which is used to drive the two paper-joining plates 111 of the paper-joining assembly 110 to open and close. When the two paper-joining plates 111 are in the second state, the first driving mechanism 160 provides a holding force to ensure that the insulating paper can be joined together when the two paper-joining plates 111 are moving.

[0028] The pressing plate 120 provided in this embodiment is located behind the paper-hugging assembly 110 and moves synchronously along the first direction. When specifically arranging the pressing plate 120 and the paper-hugging assembly 110, the gap between them is greater than 0 and less than the length of the insulating paper. For example, the distance between the pressing plate 120 and the paper-hugging assembly 110 can be different dimensions such as 1 / 2, 1 / 3, 1 / 4, or 1 / 5 of the length of the insulating paper.

[0029] As can be seen from the above description, the paper-binding device 100 provided in this application embodiment drives the paper-binding assembly 110 and the pressing plate 120 to move via the base 140. During the movement, the two opposite edges of the insulating paper are bound together by the guide surface of the paper-binding assembly 110, improving the paper-binding effect. Compared with the prior art that uses the slot 220 to accommodate the slot wedge for paper-binding, the paper-binding assembly 110 provided in this application does not occupy the slot 220 of the slot wedge, which is beneficial to increasing the magnetic flux of the motor stator 200.

[0030] In an optional embodiment, the length of the paper-binding assembly 110 along the first direction is less than the length of the insulating paper, thereby reducing the space occupied by the paper-binding assembly 110 and facilitating its movement within the paper insertion slot 210. For example, the length of the paper-binding assembly 111 can be 2 / 3, 1 / 2, 1 / 3, 1 / 4, or 1 / 5 of the length of the insulating paper. Based on the same principle, the length of the pressure plate 120 along the first direction can also be 2 / 3, 1 / 2, 1 / 3, 1 / 4, or 1 / 5 of the length of the insulating paper. This reduces the size of the paper-binding device 100 inserted into the paper insertion slot 210, and also reduces the size of the paper-binding assembly 110 and the pressure plate 120 moving into the motor stator 200 after paper-binding is completed.

[0031] In an optional embodiment, the paper-fitting assembly 110 provided in this application further includes a support 113, through which the paper-fitting plates 111 are connected to the base 140. Exemplarily, the support 113 is disposed on the base 140 to support the support 113. The support 113 may be fixed to the base 140 by a connector, which can be a threaded connector (bolt or screw), a snap-fit, a riveted connector, or other different connectors. The two paper-fitting plates 111 are slidably connected to the support 113, and the sliding direction of the two paper-fitting plates 111 is along a second direction to achieve opening and closing in the second direction.

[0032] For example, the support 113 is provided with a slide rail extending in the second direction, and two sliders 112 are slidably connected to the slide rail. The two sliders 112 are connected one-to-one with two sheet metal panels 111. Figure 4 The placement direction of the paper-forming device 100 shown is the reference direction. The slide rail is located on the lower surface of the support 113. The paper-forming board 111 is suspended on the slide rail by two sliders 112, so that the support 113 and the base 140 can be exposed outside the paper-insertion slot 210 when the paper-forming board 111 moves into the paper-insertion slot 210, ensuring that the paper-forming device 100 does not interfere with the motor stator 200 when they are engaged.

[0033] In addition to the support 113 being fixedly connected to the base 140 via a connector, the support 113 provided in this embodiment can also slide relative to the base 140. For example, the support 113 can slide back and forth relative to the base 140 in a third direction. In a specific connection, the support 113 is connected to the base 140 via a second drive mechanism 170, and the second drive mechanism 170 can drive the support 113 to move back and forth in a third direction. This adjusts the position of the paper assembly 110 in the third direction, ensuring its alignment with the insulating paper. The second drive mechanism 170 can be a drive cylinder, with its cylinder body fixed to the base 140 and its piston rod fixedly connected to the support 113. Thus, the extension and retraction of the drive cylinder can move the support 113, thereby adjusting the position of the paper assembly 111. Of course, in addition to the drive cylinder described above, other retractable drive mechanisms can be used, such as linear motors, hydraulic cylinders, or other telescopic drive mechanisms.

[0034] When the sliding fit is used as described above, when the support 113 slides to the first preset position, the bonding plate 111 is in the working position, and the bonding plate 111 can overlap with the edge of the insulating paper to complete the bonding action. When the support 113 slides to the second preset position, the bonding plate 111 is in the non-working position. In this state, the bonding assembly 110 can be raised relative to the first preset position to avoid other equipment.

[0035] Continue to refer to Figure 4 As shown, the paper-binding device 100 provided in this embodiment may further include a third drive mechanism 150. The third drive mechanism 150 is connected to the base 140 and is used to drive the base 140 to move back and forth in a third direction to adjust the height of the paper-binding assembly 110 and the pressure plate 120 as a whole. It should be understood that the third drive mechanism 150 and the second drive mechanism 170 can be used in conjunction, and the adjustment stroke of the third drive mechanism 150 is greater than that of the second drive mechanism 170. This allows for a wide range of adjustments through the third drive mechanism 150, while the second drive mechanism 170 only adjusts the height of the paper-binding assembly 110 within a small range.

[0036] In one feasible embodiment, at least one of the two sheet metal pieces 111 in the sheet metal assembly 110 is floatingly connected to the support 113 in a first direction. The sheet metal assembly 110 also includes a first elastic element for pushing the sheet metal piece 111 floatingly connected to the support 113 to slide in the first direction, so as to increase the length of the insulating paper clamped by the two sheet metal pieces 111 by the floating of the sheet metal piece 111 and the support 113.

[0037] For example, the end face of the motor stator 200 is a circumferential surface, and the length direction of the paper insertion slot 210 does not extend along the diameter of the circumferential surface, with a certain angle between them. This results in inconsistent lengths of the two sidewalls of the U-shaped insulation protruding from the outer wall of the motor stator 200 when the insulating paper is inserted into the paper insertion slot 210. Furthermore, because the motor stator 200 has a circular structure, the distances from the two bonding plates 111 to the motor stator 200 along the first direction are inconsistent. Therefore, during the movement of the two bonding plates 111 of the bonding assembly 110 along the first direction from the opening and closing to the first state, the bonding plates 111, upon contacting the outer wall of the motor stator 200, can allow the base 140 to continue moving through a floating connection. When the two bonding plates 111 close from the first state to the second state, the pushing action of the first elastic element allows the floatingly connected bonding plates 111 to continuously abut against the outer wall of the motor stator 200, increasing the length of the bonding plates 111 when clamping the insulating paper, thereby improving the bonding effect.

[0038] When at least one of the paperboards 111 in the paperboard assembly 110 is floatingly connected to the support 113, it can be that both paperboards 111 are floatingly connected to the support 113, or only one of the paperboards 111 is floatingly connected to the support 113, while the other paperboard 111 is fixedly connected to the support 113.

[0039] For ease of description, the two sheet metal pieces 111 are designated as first sheet metal piece 1111 and second sheet metal piece 1112, respectively. The first sheet metal piece 1111 has a smaller distance from the motor stator 200 along the first direction, while the second sheet metal piece 1112 has a larger distance from the motor stator 200 along the first direction. When only one sheet metal piece 111 is used for floating connection with the support 113, the first sheet metal piece 1111 and the support 113 are floatingly connected, while the second sheet metal piece 1112 and the support 113 are relatively fixed relative to each other along the first direction. Figure 6 As shown, when the first bonding plate 1111 and the second bonding plate 1112 are in the first state, the first bonding plate 1111 abuts against the outer wall of the motor stator 200 and can float. Specifically, as the base 140 moves, the first bonding plate 1111 first abuts against the outer wall of the motor stator 200, and as the bonding assembly 110 continues to move in the first direction, the first bonding plate 1111 floats relative to the support 113, and the first elastic element is compressed. When the first bonding plate 1111 and the second bonding plate 1112 are closed, the first bonding plate 1111 can remain abut against the outer wall of the motor stator 200, so that when clamping insulating paper, the first bonding plate 1111 and the second bonding plate 1112 can clamp a longer piece of insulating paper, thereby improving the bonding effect.

[0040] Continue to refer to Figure 4For ease of description, the two sliders 112 are named first slider 1121 and second slider 1122, respectively. First slider 1121 corresponds to first sheet metal 1111, and second slider 1122 corresponds to second sheet metal 1112. First sheet metal 1111 and first slider 1121 are slidably connected, with the sliding direction along a first direction; second sheet metal 1112 and second slider 1122 are fixedly connected, with the support 113 fixed along the first direction.

[0041] For example, the first sheet metal 1111 and the first slider 1121 are slidably connected by a slide rail. In addition, the two ends of the first elastic member are respectively pressed between the first sheet metal 1111 and the first slider 1121, so that when the first sheet metal 1111 presses against the outer wall of the motor stator 200, the elastic force of the first elastic member pushes the first sheet metal 1111 to move along the second direction and abut against the side wall of the motor stator 200.

[0042] The second sheet metal 1112 and the second slider 1122 can be fixedly connected by connectors, such as threaded connectors, riveting connectors, etc., or by bonding, welding, etc.

[0043] During the bonding process, the two edges of the insulating paper overlap via guide surfaces on the first bonding plate 1111 and the second bonding plate 1112. Specifically, the guide surfaces on both the first bonding plate 1111 and the second bonding plate 1112 are curved surfaces. Each curved surface can bend the edge of the insulating paper from a vertical guide as the corresponding bonding plate 111 moves along a first direction. Furthermore, the two curved surfaces satisfy the following condition: during guidance, the bending amplitude of the two edges of the insulating paper differs to ensure that the two edges can overlap after bending, thus forming the bonded paper.

[0044] like Figure 4 , Figure 5 and Figure 7 As shown, in an optional embodiment, the paper-binding device 100 provided in this application further includes a slot wedge insertion mechanism 130. This mechanism 130 inserts a slot wedge into a groove 220 formed on the side wall of the paper insertion slot 210, thereby holding the insulating paper in a bound state. When the slot wedge insertion mechanism 130 is provided, it is located on the side of the pressure plate 120 opposite to the paper-binding assembly 110, and is slidably connected to the base 140. The sliding direction of the slot wedge insertion mechanism 130 is along a first direction, and it can press against the outer wall of the motor stator 200.

[0045] In practical use, such as Figure 8 and Figure 9 As shown, the paper-joining assembly 110 and the pressing plate 120 first enter the paper insertion slot 210 to join the insulating paper. As the base 140 moves along the first direction, as... Figure 10 As shown, the slot wedge insertion mechanism 130 contacts the motor stator 200 and is held in a position against the outer wall of the motor stator 200 by sliding. After the paper-binding assembly 110 and the pressing plate 120 complete the paper-binding, the slot wedge can be inserted into the slot body 220 through the slot wedge insertion mechanism 130.

[0046] It should be understood that the aforementioned slot wedge insertion mechanism 130 includes a hopper and a pushing mechanism. The hopper is slidably connected to the base 140, and multiple slot wedges are stacked along a third direction within the hopper. The pushing mechanism is located on the side of the hopper away from the pressure plate 120. When a slot wedge needs to be inserted, the pushing mechanism pushes the lowest slot wedge in the hopper into the slot 220 on the side wall of the insertion slot 210, thereby completing the slot wedge insertion. It should be understood that the pushing mechanism can be a common linear drive mechanism 160, such as a linear motor, a drive cylinder, or a drive hydraulic cylinder.

[0047] In an alternative embodiment, to ensure the hopper abuts against the outer wall of the motor stator 200, a second elastic member is included. One end of the second elastic member abuts against the slot wedge insertion mechanism 130, and the other end abuts against the base 140. When the slot wedge insertion mechanism 130 abuts against the outer wall of the motor stator 200, and the base 140 continues to move in the first direction, the slot wedge insertion mechanism 130 slides relative to the base 140, and the second elastic member is compressed, so that the elastic force provided by the second elastic member causes the slot wedge insertion mechanism 130 to abut against the outer wall of the motor stator 200.

[0048] It should be understood that the elastic elements (such as the first elastic element and the second elastic element) provided in the embodiments of this application can be common elastic elements such as metal springs or rubber springs. Of course, in addition to the elastic elements in the examples above, other elastic structures that can provide driving force can also be used.

[0049] Continue to refer to Figure 7 As shown, the base 140 includes an L-shaped support plate 142 and a horizontal plate 141 fixedly connected to the L-shaped support plate 142; wherein, the paper-hugging assembly 110 is connected to the L-shaped support plate 142, while the pressing plate 120 and the slot wedge insertion mechanism 130 are both connected to the horizontal plate 141. Specifically, a support block 143 is fixedly connected to the horizontal plate 141, the pressing plate 120 is fixed to the support block 143, and the slot wedge insertion mechanism 130 is slidably connected to the support block 143. Figure 7 As shown, the slot wedge insertion mechanism 130 is connected to a slide rod 180. The support block 143 is provided with a through hole. The slide rod 180 passes through the through hole and can slide relative to the support block 143. The second elastic member can be fitted onto the slide rod 180. One end of the second elastic member abuts against the slide rod 180 or the slot wedge insertion mechanism 130, and the other end abuts against the support block 143.

[0050] In one alternative embodiment, there are two slide rods 180, and the two slide rods 180 can be arranged in a second direction to improve the stability of the slot wedge insertion mechanism 130 during sliding. In addition, a limit structure is provided at the end of the slide rod 180 away from the slot wedge insertion mechanism 130 to prevent the slide rod 180 from sliding out of the support block 143.

[0051] This application also provides a paper-binding system, which includes at least two axial motor paper-binding devices 100 as described above, wherein the at least two axial motor paper-binding devices 100 are arranged around the motor stator 200.

[0052] In the above technical solution, the base 140 drives the paper-binding assembly 110 and the pressing plate 120 to move.
