Abstract
Description
Technical Field
[0001] The utility model relates to the field of assembly and processing structures of segmented motor stators, and particularly to a device for assembling a connector of a motor stator after winding. Background Art
[0002] In the process of manufacturing a motor stator, it is necessary to assemble the stator after winding the copper wire with a connector and then enter the subsequent production process.
[0003] The copper wires on the stator are distributed alternately around the stator with one long and one short. The copper wires are in a free state. The long copper wires are more likely to bend, with a larger bending angle and an unfixed bending direction. There is no mechanism for hooking copper wires on the existing device, and the size of the flared mouth of the wire pusher is limited. If the bending angle of the copper wire is too large when the wire pusher fixes the copper wire, the wire pusher will hit the copper wire, resulting in the copper wire being unable to penetrate into the connector normally and causing poor wire threading.

[0060] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0061] As Figure 1 and Figure 2 shown, it includes a stator assembly A0, a stator lifting and rotating mechanism B0, a WPC tray C0, a connector assembly mechanism D0 and an assembly line F0. The main structure of this device is: a connector handling mechanism E0 is provided above the connector assembly mechanism D0, an assembly line F0 is below the connector assembly mechanism D0, the stator lifting and rotating mechanism B0 is located below the assembly line F0, the stator assembly A0 is loaded on the WPC tray C0 and transported along the assembly line F0, and the WPC tray C0 is a carrier for the stator A2 of the stator assembly A0 to move on the assembly line F0.
[0062] As Figure 3 and Figure 4 shown, the stator assembly A0 includes a connector A1 and a stator A2. The stator A2 is first loaded on the WPC tray C0, and the connector A1 is mounted on the connector handling mechanism E0. The device of the present invention is to position and mount the connector A1 on the connector handling mechanism E0 onto the stator A2 on the WPC tray C0.
[0063] The stator A2 and the WPC tray C0 are transported by the assembly line F0. The stator lifting and rotating mechanism B0 is used to lift and move the WPC tray C0 and the stator A2 thereon into the connector assembly mechanism D0. The connector assembly mechanism D0 positions the coil wire ends of the stator A2, and then the connector handling mechanism E0 drives the connector A1 to descend for mating installation with the stator A2.
[0064] The structure of the stator lifting and rotating mechanism B0 is as Figure 5 shown, and it includes a stator lifting mechanism and a stator rotating mechanism. The stator A2 is lifted by the stator lifting mechanism, and the stator rotating mechanism drives the stator A2 to rotate itself for circumferential positioning.
[0065] As Figure 6 shown, the WPC tray C0 includes a tray base C1, a stator base C2, a guide ring C3, a stator positioning jig C4, and a stator positioning key C5. The tray base C1 is located on the assembly line F0. The guide ring C3 is mounted on the tray base C1 through the stator base C2. The stator base C2 and the guide ring C3 are hollow in the middle. The stator positioning jig C4 is mounted on the guide ring C3. The stator A2 of the stator assembly A0 is mounted on the stator positioning jig C4. A stator positioning key C5 that mates with the stator A2 is provided at the top of the stator positioning jig C4.
[0066] As Figure 1 shown, the product stator A2 is fixed on the WPC tray C0 and enters the connector assembly station. As Figure 6 shown, the parts inside the WPC tray C0, namely the stator base C2 and the guide ring C3, are designed to be hollow. In this way, the lifting end of the stator lifting and rotating mechanism B0 rises through the above-mentioned hollow positions of the stator base C2 and the guide ring C3 to lift the stator A2. After lifting a certain distance, the stator rotating mechanism of the stator lifting and rotating mechanism B0 rotates the stator A2 to an appropriate angle. Then, the stator lifting mechanism of the stator lifting and rotating mechanism B0 continues to lift the stator A2 upward so that it enters the connector assembly mechanism D0. At this time, the state of the stator is as Figure 19 shown.
[0067] As Figure 7 and Figure 8As shown, the connector assembly mechanism D0 includes an assembly mechanism base plate D1, an outer ring baffle D18, a wire-hooking base D19, a wire-hooking positioning structure, a cylinder assembly, and a hard stop assembly. The assembly mechanism base plate D1 is fixed and located above the assembly line F0. The wire-hooking base D19 is fixed in the middle of the assembly mechanism base plate D1, and the outer ring baffle D18 is fixed on the peripheral edge around the wire-hooking base D19. Above the outer ring baffle D18, there is a cover plate D13 for capping, and it is capped by the cover plate D13. An outer ring baffle D18 encloses a wire-hooking base D19 in the middle, and a wire-hooking positioning structure that drives a wire-pushing fork and a wire-hooking fork is installed thereon; around the wire-hooking base D19, there are arranged a cylinder assembly and a hard stop assembly. The cylinder assembly is connected to the rotating disk of the wire-hooking positioning structure to drive the wire-pushing fork and the wire-hooking fork in the wire-hooking positioning structure to move, and the hard stop assembly is used to limit and block the movement of the wire-hooking positioning structure.
[0068] In a specific implementation, side through slots for the handle parts of the wire-pushing rotating disk D23, the wire-hooking disk D12, and the wire-hooking fork rotating disk D30 to extend are respectively opened on the outer ring baffle D18.
[0069] The internal structure of the wire-hooking positioning structure is divided into upper and lower layers. The upper layer, as shown in Figure 8 , 9 , Figure 10, plays a role in positioning the copper wire, and the lower layer, as shown in Figure 12 , 14 , Figure 14, plays a role in hooking the copper wire.
[0070] The wire-hooking positioning structure includes upper and lower layers.
[0071] As shown in Figures 8 - 11 , the upper layer includes a wire-pushing rotating disk D23, a first stepped pin D27, a wire-pushing base plate D28, a first wire-pushing fork D25, and a second wire-pushing fork D26; the inner edge of the annular wire-pushing base plate D28 is fixed to the bottom surface of the cover plate D13. There is a clearance space between the wire-pushing base plate D28 and the cover plate D13, and the wire-pushing rotating disk D23 is rotatably installed in the clearance space. A plurality of first wire-pushing forks D25 and a plurality of second wire-pushing forks D26 are installed at the bottom of the wire-pushing base plate D28. The first wire-pushing fork D2 and the second wire-pushing fork D26 are alternately installed at intervals along the circumferential direction at the bottom of the wire-pushing base plate D28. After each first wire-pushing fork D25 / second wire-pushing fork D26 is installed at the bottom of the wire-pushing base plate D28, it can only move radially along the wire-pushing base plate D28.
[0072] As shown in Figure 29 , a plurality of wire-pushing inclined slots are arranged at intervals along the circumferential direction on the wire-pushing rotating disk D23. The wire-pushing inclined slots are not arranged along the radial or circumferential direction, but are arranged at an angle between the radial and circumferential directions. All the wire-pushing inclined slots are arranged at intervals along an approximate circumference with a unified clockwise or counterclockwise spiral rotation direction; as shown in Figure 28 , a plurality of wire-pushing waist-shaped slots are arranged at intervals along the circumferential direction on the wire-pushing base plate D28, and each wire-pushing waist-shaped slot is arranged along the radial direction.
[0073] One first stepped pin D27 is installed in each wire pushing diagonal slot. Each first stepped pin D27 passes through a wire pushing waist-shaped slot formed in the wire pushing bottom plate D28 and is inserted into a hole formed at the outer end of a first wire pushing fork D25 / second wire pushing fork D26. Thereby, the wire pushing rotating disk D23 is rotated, driving the first stepped pin D27 to drive the first wire pushing fork D25 / second wire pushing fork to move radially under the radial limit of the wire pushing waist-shaped slot of the wire pushing bottom plate D28.
[0074] The number of wire pushing waist-shaped slots on the wire pushing bottom plate D28, the number of wire pushing diagonal slots on the wire pushing rotating disk D23, and the total number of the first wire pushing forks D2 and the second wire pushing forks D26 are the same. One wire pushing waist-shaped slot on the wire pushing bottom plate D28, one wire pushing diagonal slot on the wire pushing rotating disk D23, and one wire pushing fork D2 correspond to each other.
[0075] In a specific implementation, the first stepped pin D27 is provided with three levels of steps, and the three levels of steps from small to large are respectively used to adapt to the aperture of the hole of the first wire pushing fork D25 / second wire pushing fork D26, the slot width of the wire pushing waist-shaped slot of the wire pushing bottom plate D28, and the slot width of the wire pushing diagonal slot of the wire pushing rotating disk D23.
[0076] Such as Figure 18 and Figure 28 As shown, a dovetail groove penetrating radially is formed at the bottom of the wire pushing bottom plate D28. A wire pushing waist-shaped slot is formed at the top of the wire pushing bottom plate D28 above each dovetail groove. A dovetail protrusion matching the dovetail groove is provided at the top of the first wire pushing fork D25 / second wire pushing fork D26. The dovetail protrusion of the first wire pushing fork D25 / second wire pushing fork D26 is slidably installed in the dovetail groove, so that the first wire pushing fork D25 / second wire pushing fork D26 is limited to move radially along the wire pushing bottom plate D28.
[0077] Such as Figures 12 - 15 As shown, the lower layer includes a wire hooking disk D12, a wire hooking fork D24, a second stepped pin D29, and a wire hooking fork rotating disk D30; the annular wire hooking fork rotating disk D30 is rotatably installed on the wire hooking base D19. A clearance space is provided between the wire hooking fork rotating disk D30 and the wire hooking base D19. The wire hooking disk D12 is rotatably installed in the clearance space. A plurality of wire hooking forks D24 are installed at the top of the wire hooking fork rotating disk D30. The plurality of wire hooking forks D24 are circumferentially spaced and installed at the top of the wire hooking fork rotating disk D30. After each wire hooking fork D24 is installed at the top of the wire hooking fork rotating disk D30, it can only move radially along the wire hooking fork rotating disk D30.
[0078] Such as Figure 26As shown, a plurality of wire-hooking diagonal slots are circumferentially spaced on the wire-hooking disc D12. The wire-hooking diagonal slots are not arranged along the radial or circumferential direction, but at an angle between the radial and circumferential directions. All the wire-hooking diagonal slots are spaced along an approximate circumference with a unified clockwise or counterclockwise helical rotation direction; as Figure 27 As shown, a plurality of wire-hooking waist-shaped slots are circumferentially spaced on the wire-hooking fork rotating disc D30. Each wire-hooking waist-shaped slot is arranged along the radial direction.
[0079] A second stepped pin D29 is installed in each wire-hooking diagonal slot. Each second stepped pin D29 passes through a wire-hooking waist-shaped slot opened on the wire-hooking fork rotating disc D30 and is inserted into a hole opened at the outer end of a wire-hooking fork D24; thus, when the wire-hooking disc D12 rotates, it drives the first stepped pin D27 to drive the wire-hooking fork D24 to move radially under the radial limit of the wire-hooking waist-shaped slot of the wire-hooking fork rotating disc D30.
[0080] The number of wire-hooking waist-shaped slots on the wire-hooking fork rotating disc D30, the number of wire-hooking diagonal slots on the wire-hooking disc D12, and the number of wire-hooking forks D24 are all the same. One wire-hooking waist-shaped slot on a wire-hooking fork rotating disc D30, one wire-hooking diagonal slot on the wire-hooking disc D12, and one wire-hooking fork D24 correspond to each other.
[0081] In a specific implementation, the second stepped pin D29 is provided with three levels of steps, and the three levels of steps from small to large are respectively used to adapt to the aperture of the hole of the wire-hooking fork D24, the slot width of the wire-hooking waist-shaped slot of the wire-hooking fork rotating disc D30, and the slot width of the wire-hooking diagonal slot of the wire-hooking disc D12.
[0082] As Figure 16 and Figure 27 As shown, the top of the wire-hooking fork rotating disc D30 is provided with a dovetail groove that penetrates radially. A wire-hooking waist-shaped slot is opened at the bottom of the wire-hooking fork rotating disc D30 above each dovetail groove. The top of the wire-hooking fork D24 is provided with a dovetail protrusion that matches the dovetail groove. The dovetail protrusion of the wire-hooking fork D24 is slidably installed in the dovetail groove so that the wire-hooking fork D24 is limited to move radially along the wire-hooking fork rotating disc D30.
[0083] As Figure 17 As shown, there is an obvious gap between the lower wire-hooking fork D24 and the upper first wire-pushing fork D25 and second wire-pushing fork D26, and the forks of the upper and lower layers do not contact. And the spiral rotation directions of the wire-pushing diagonal slots on the wire-pushing rotating disc D23 and the wire-hooking diagonal slots on the wire-hooking disc D12 are opposite.
[0084] In the wire-hooking positioning structure, the wire-pushing rotating disc D23, the wire-hooking disc D12, and the wire-hooking fork rotating disc D30 are all fixedly provided with handle parts that extend out of the outer ring baffle D18, and the handle parts are used to connect with the cylinder assembly,
[0085] The cylinder assembly includes a first cylinder D2, a cylinder fixing block D3, a second cylinder D4, a first floating head D5, a first connecting rod D7, a cylinder seat D8, a third cylinder D9, a second floating head D10, and a third floating head D22; the cylinder fixing block D3 is fixed on the bottom plate D1 of the assembling mechanism and is located on one side around the thread hooking base D19. One end of the cylinder fixing block D3 is hinged to the cylinder block of the first cylinder D2, and the cylinder rod of the first cylinder D2 is fixedly connected to the third floating head D22. The third floating head D22 is hinged to the handle part extending out of the outer ring baffle D18 through a third connecting shaft D21 and a wire pushing rotating disk D23; the other end of the cylinder fixing block D3 is hinged to the cylinder block of the second cylinder D4, and the cylinder rod of the second cylinder D4 is fixedly connected to the first floating head D5. The first floating head D5 is hinged to one end of the first connecting rod D7 through a first connecting shaft D6; one end of the first connecting rod D7 is simultaneously hinged to the handle part extending out of the outer ring baffle D18 of the thread hooking fork rotating disk D30; the other end of the first connecting rod D7 is fixedly connected with a cylinder seat D8, the cylinder seat D8 is hinged to the cylinder block of the third cylinder D9, and the cylinder rod of the third cylinder D9 is fixedly connected to the second floating head D10. The second floating head D10 is hinged to the handle part extending out of the outer ring baffle D18 of the thread hooking disk D12 through a second connecting shaft D11.
[0086] The third cylinder D9 is connected to the thread hooking disk D12 through the floating head D10 and the second connecting shaft D11. The first connecting rod D7 is fixedly connected to the thread hooking fork rotating disk D30 and the cylinder seat D8. The cylinder seat D8 is connected to the third cylinder D9 through a cylinder upper rotating shaft. The inner ring of the outer ring baffle D18 is in contact with the outer rings of both the thread hooking disk D12 and the thread hooking fork rotating disk D30, and restricts the thread hooking disk D12 and the thread hooking fork rotating disk D30 to only perform circular rotational motion around the center of the outer ring baffle D18.
[0087] Similarly, the first cylinder D2 is fixed to the third floating head D22. The third floating head D22 is connected to the wire pushing rotating disk D23 through the third connecting shaft D21. The cover plate D13 is fixed to the outer ring baffle D18 and the wire pushing bottom plate D28. The outer circle of the wire pushing bottom plate D28 is in contact and fixed with the inner circle of the outer ring baffle D18. The outer circle and the inner circle of the wire pushing rotating disk D23 are respectively between the inner ring of the outer ring baffle D18 and the step outer circle of the wire pushing bottom plate D28. The wire pushing rotating disk D23 can only perform circular rotational motion around the center of the outer ring baffle D18 under the common restraint of the outer ring baffle D18 and the wire pushing bottom plate D28.
[0088] The thread hooking disk D12, the thread hooking fork D24, and the thread hooking fork rotating disk D30 are connected together by a second step pin D29. The second step pin D29 is divided into three sections. The lowermost section is installed in the notch of the thread hooking disk D12, the middle section is installed in the notch of the thread hooking fork rotating disk D30, and the uppermost section is fixed to the thread hooking fork D24. The thread hooking fork D24 is restricted to only perform linear motion by the slot feature of the dovetail groove at the top of the thread hooking fork rotating disk D30.
[0089] The upper end of the first step pin D27 is fitted with the inner notch of the wire-pushing rotating disk D23, the middle is fitted with the inner notch of the wire-pushing bottom plate D28, and the lower end is fixedly connected to the first wire-pushing fork D25 and the second wire-pushing fork D26. The hooks on the connector A1 for threading copper wires have two levels of height, and the wire-clamping grooves of the first wire-pushing fork D25 and the second wire-pushing fork D26 for fixing the copper wires are designed to be one long and one short.
[0090] In this way, the wire-pushing rotating disk D23, the wire-hooking fork rotating disk D30, and the wire-hooking disk D12 are respectively driven by the first cylinder D2, the second cylinder D4, and the third cylinder D9 to rotate, and the rotation of the wire-hooking fork rotating disk D30 drives the wire-hooking disk D12 to rotate together.
[0091] Among the above, the first connecting rod D7, the cylinder seat D8, the third cylinder D9, the second floating head D10, the wire-hooking disk D12, and the wire-hooking fork rotating disk D30 form an overall quadrilateral structure. When the rod of the second cylinder D4 extends and retracts, it drives the overall quadrilateral structure to rotate around the center of the wire-hooking base D19 together.
[0092] As Figures 30 - 32 shown, the wire-hooking fork D24, the first wire-pushing fork D25, and the second wire-pushing fork D26 are all provided with wire-clamping grooves for hooking copper wires, holes for pins to pass through, and protruding structures for mating with dovetail grooves.
[0093] As Figure 25 shown, the connector handling mechanism E0 includes a connector horizontal handling module E1, a connector lifting handling module E2, a connector press head E3, and a jaw E4; both the connector horizontal handling module E1 and the connector lifting handling module E2 are mainly assembled with a structure of guide rails and sliders. The guide rail of the connector horizontal handling module E1 remains fixed, the guide rail of the connector lifting handling module E2 is installed on the slider of the connector horizontal handling module E1, the connector press head E3 is installed on the slider of the connector lifting handling module E2, and the extending end of the connector press head E3 is fixedly connected to the jaw E4.
[0094] The hard stop assembly includes a second hard stop seat D20, a hard stop block D15, an oil buffer D16, and a first hard stop seat D17. The second hard stop seat D20 is fixed on the assembly mechanism bottom plate D1 near the third floating head D22 for limiting the movement of the handle part of the wire-pushing rotating disk D23; the first hard stop seat D17 is fixed on the assembly mechanism bottom plate D1 where there is no second hard stop seat D20 and the cylinder assembly for limiting the movement of the handle part of the wire-hooking fork rotating disk D30.
[0095] The wire-hooking fork rotating disc D30 is fixedly provided with a handle part at the side where the second hard stop seat D20 and the cylinder assembly are not provided. One end of the handle part of the wire-hooking fork rotating disc D30 is fixedly connected to one end of the second connecting rod D14, and the other end of the second connecting rod D14 is fixedly connected to the hard stop block D15; the oil buffer D16 is installed on the first hard stop seat D17.
[0096] The implementation working process of the present utility model is as follows:
[0097] The original state is as Figure 19 shown.
[0098] First, the third cylinder D9 extends, pushing the wire-hooking disc D12 to rotate around the center of the outer ring baffle D18, and the wire-hooking disc D12 pushes the second step pin D29 to move; at the same time, the second cylinder D4 does not work and remains stationary, and the wire-hooking fork rotating disc D30 is fixed under the action of the second cylinder D4. Therefore, the second step pin D29 can only move in a radial straight line under the common constraint of the slots of the two parts of the wire-hooking disc D12 and the wire-hooking fork rotating disc D30, thereby pushing the wire-hooking fork D24 to extend, located on the side of the longer copper wire. At this time, the state is as Figure 20 shown.
[0099] Then the second cylinder D4 extends, pushing the components D7, D8, D9, D10, D11, D12, D24, D29, D30 as a whole to rotate in a circular motion together, so that the wire-hooking fork D24 hooks and fixes the wire end of the longer copper wire. At this time, the state is as Figure 21 shown.
[0100] The conversion of force and motion during the operation of the wire-hooking mechanism is as Figure 23 shown. The thrust F1 when the third cylinder D9 extends is converted into the force F2 for the circumferential rotation of the wire-hooking fork rotating disc D30, and then is converted into the force F3 for the extension of the wire-hooking fork D24 under the action of the second step pin D29; the thrust F4 when the second cylinder D4 extends is converted into the force F5 for D7, D8, D9, D10, D11, D12, D24, D29, D30 to rotate in a circular motion together around the center of the outer ring baffle D18.
[0101] Next, the first cylinder D2 extends, pushing the wire-pushing rotating disc D23 to rotate around the center of the outer ring baffle D18, and the wire-pushing rotating disc D23 pushes the first step pin D27 to move. Since the first wire-pushing fork D25 and the second wire-pushing fork D26 are matched with the inner slot of the wire-pushing bottom plate D28, the dovetail groove slot feature in the wire-pushing bottom plate D28 restricts the first wire-pushing fork D25 and the second wire-pushing fork D26 to only move in a straight line along the slot direction. Therefore, the wire-pushing rotating disc D23 pushes the first wire-pushing fork D25 and the second wire-pushing fork D26 to extend through the first step pin D27.
[0102] As Figure 31 、 Figure 32As shown, the wire slot for fixing the copper wire on the first wire pushing fork D25 and the second wire pushing fork D26 adopts a flared design with a larger outer diameter and a smaller inner diameter. In this way, under the guiding action of the flared opening, the copper wire is fixed in the wire slot. The first wire pushing fork D25 hooks the end of the longer copper wire, and the second wire pushing fork D26 hooks the end of the shorter copper wire. At this time, both the wire hooking fork D24 and the first wire pushing fork D25 hook the longer copper wire. The wire hooking fork D24 hooks from the lower side, and the first wire pushing fork D25 hooks from the upper side. The state at this time is as Figure 22 shown.
[0103] The conversion of force and motion in this process is as Figure 24 shown. The thrust F6 of the first cylinder D2 of the air cylinder is converted into the force F7 for the wire pushing rotating disk D23 to rotate. The wire pushing rotating disk D23 converts the rotational motion into the force F8 for the first wire pushing fork D25 and the second wire pushing fork D26 to extend through the first step pin D27.
[0104] The connector handling mechanism E0 grabs the connector A1 and transports it above the connector assembly mechanism D0. The connector lifting and handling module E2 descends a certain distance, causing the connector A1 to descend and penetrate into the copper wire of the stator A2 for a certain distance. Then, the third cylinder D9, the second cylinder D4, and the first cylinder D2 retract respectively, driving the wire hooking fork D24, the first wire pushing fork D25, and the second wire pushing fork D26 to retract to their original positions. Then, the stator lifting and rotating mechanism B0 jacks the stator upward again to assemble the stator A2 and the connector A1 in place. During this process, due to the retraction of the first wire pushing fork D25 and the second wire pushing fork D26, the copper wire of the stator A2 loses restraint, and the copper wire will rebound, resulting in friction when the copper wire contacts the hook of the connector A1. A connector press head E3 is designed above the connector A1; the connector press head E3 closely adheres to the upper surface of the connector A1 to prevent the stator A2 from jacking up the connector A1 and causing misassembly.
[0105] After the stator A2 and the connector A1 are assembled, the clamping jaw E4 releases the connector, and the connector handling mechanism E0 goes to grab the next connector; the stator lifting and rotating mechanism resets, leaving the assembled stator assembly A0 on the WPC tray C0. This station ends, and the WPC tray C0 flows into the next station.
