[0003] During the flat wire motor production process, the flat wire is processed into U-shaped pins (U-PINs) according to a predetermined length. The wires are inserted along the various slots of the stator through a flat wire insertion device, and then twisted at the ends of the pins. The twisted pins are connected to each other by welding to form a loop in the flat wire motor stator. In addition, since multiple specifications of pins are usually used in the same stator product, the production equipment is capable of producing stator pins of various specifications to meet assembly requirements.

[0041] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0042] Although the present application can be easily embodied as different forms of embodiments, only some specific embodiments are shown in the drawings and will be described in detail in the present specification, and it can be understood that the present specification should be regarded as a demonstrative description of the principles of the present application, and is not intended to limit the present application to that described herein.

Furthermore, it should be noted that this specification describes many features.

These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.

[0045] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a structural diagram of a stator card issuing and distributing device 10 provided in an embodiment of the present utility model. Figure 2 yes Figure 1 The structural diagram of the conveying component 11, the guiding component 12 and the shifting component 13 in the stator card issuing and distributing device 10 is shown. Figure 3 yes Figure 1 The structural diagram of a transfer mechanism 14 in the stator card issuing and distributing device 10 is shown. Figure 3 The figure shows a schematic structural diagram of any transfer mechanism 14 in the stator card issuing and material distributing device 10 . The stator card issuing and material distributing device 10 may include: a conveying component 11 , a guide component 12 and at least two transfer mechanisms 14 .

[0046] The conveyor assembly 11 can be used to transport stator hairpins 20 of different sizes along its extension direction E1. At least two transfer mechanisms 14 can be located at the output end of the conveyor assembly 11, and are used to move the stator hairpins 20 of different sizes to the next workstation via the corresponding transfer mechanisms 14 in a direction away from the ground or close to the ground. A plurality of spacers 1432 are provided at intervals along the extension direction of the transfer mechanisms 14 to separate the stator hairpins 20. For example, the transfer mechanisms 14 can be lifting mechanisms that can lift the stator hairpins 20 to the next workstation.

[0047] The guide assembly 12 may include two spaced apart stopper ridges 121 installed above the conveyor assembly 11 and forming a guide track with the conveyor assembly 11. The ends of the two stopper ridges 121 are adapted to move relative to the width direction E2 of the conveyor assembly 11. The guide track is shaped to allow the stator hairpin 20 to pass through and then dock with a transfer mechanism 14 of corresponding specifications. The stator hairpin 20 can move within the guide track toward the corresponding transfer mechanism 14.

[0048] With this structural design, stator clips 20 of varying specifications can be conveyed to the transfer mechanism 14 corresponding to their specifications via the guide assembly 12. During the transfer process, the stator clips 20 can be sorted and fed according to their specifications, simplifying the feeding process and reducing the difficulty of subsequent processes. Furthermore, the stator clip 20 conveying path can be adjusted quickly, improving production efficiency and the applicability of the stator clip sorting device 10.

[0049] In an optional embodiment, the conveying assembly 11 may include a support base 111 and a conveyor belt 112 wound on the support base 111, the conveyor belt 112 has a feed end and an output end, the conveyor belt 112 can move around the support base 111 to convey the stator hairpin 20 from the feed end to the output end, and the side of the conveyor belt 112 facing away from the ground moves along the extension direction E1 of the conveying assembly 11, and the conveyor belt 112 is used to convey stator hairpins 20 of various specifications.

[0050] The front end of the limiting ridge 121 can be fixedly connected to the support base 111, and the end of the limiting ridge 121 is located on the conveyor belt 112. The guide component 12 is used to guide stator hairpins 20 of various specifications. The stator hairpins 20 located on the conveyor belt 112 can be transported to the specified position under the action of the guide component 12.

[0051] The shift assembly 13 is mounted on the support base 111 and connected to the ends of the two limiting ridges 121. The shift assembly 13 is configured to move the ends of the two limiting ridges 121 along the width direction of the conveyor assembly 11. The width direction E2 of the conveyor assembly 11 is perpendicular to the direction of extension of the conveyor assembly 11. In other words, through the cooperation of the shift assembly 13 and the guide assembly 12, stator hairpins 20 of different sizes located on the conveyor belt 112 can be transported to at least two locations under the guidance of the guide assembly 12.

[0052] At least two transfer mechanisms 14 correspond to at least two positions on the conveyor belt 112. The end of the transfer mechanism 14 closest to the conveyor assembly 11 is located on the ground side of the corresponding position on the conveyor belt 112. The transfer mechanism 14 is used to lift the stator hairpin 20. In other words, the transfer mechanism 14 can be used to receive the stator hairpin 20 that has fallen from the corresponding position on the conveyor belt 112 and transport the received stator hairpin 20 to a predetermined position, which can be a position where the loading mechanism in the next process can grasp it. The at least two transfer mechanisms 14 can be arranged along the width direction E2 of the conveyor assembly 11, and at least two transfer mechanisms 14 can be located on the side of the output end of the conveyor belt 112 that is away from the feed end of the conveyor belt 112.

[0053] Through the above-mentioned structural design, the stator hairpin 20 formed by the production equipment can be placed on the conveying component 11, and the shifting component 13 moves the ends of the two limiting ridges 121 to the specified positions according to the specifications of the stator hairpin 20. The conveying component 11 conveys the stator hairpin 20 in the direction close to at least two transfer mechanisms 14. During the conveying process, the stator hairpin 20 moves to the specified position under the action of the guide component 12, and falls from the specified position to the transfer mechanism 14 corresponding to the position, and the transfer mechanism 14 conveys the stator hairpin 20 to the preset position (i.e., the next workstation).

[0054] Moreover, since the shifting assembly 13 can drive the ends of the two limiting ridges 121 to move between at least two positions on the conveyor belt 112, and the at least two positions on the conveyor belt 112 correspond one-to-one to at least two transfer mechanisms 14, for stator hairpins 20 of different specifications, the stator hairpins 20 can be conveyed to the transfer mechanism 14 corresponding to its specifications through the shifting assembly 13 and the guide assembly 12. In the process of transmitting the stator hairpins 20, the stator hairpins 20 can be classified and fed according to the specifications of the stator hairpins 20, which can simplify the feeding process of the stator hairpins 20 and reduce the difficulty of the subsequent operations.

[0055] By providing a shift component 13 and a guide component 12, the stator hairpin 20 on the conveying component 11 can be guided. The shift component 13 drives the ends of the two limiting ridges 121 to move, and the positions of the ends of the two limiting ridges 121 can be adjusted, thereby changing the position of the stator hairpin 20 on the conveying component 11 output from the conveyor belt 112. This not only can quickly respond to the adjustment of the conveying path of the stator hairpin 20 and improve production efficiency, but also can realize the efficient transfer of stator hairpins 20 of various specifications, which can improve the applicability of the stator hairpin dividing device 10.

[0056] Please refer to Figure 1 and Figure 2In an exemplary embodiment, the stator hairpin material distribution device includes two transfer mechanisms 14 (a first transfer mechanism and a second transfer mechanism), and the shifting assembly 13 can drive the ends of the two limiting ridges 121 to move between two positions (a first position and a second position) of the conveyor belt 112. The first position on the conveyor belt 112 corresponds to the first transfer mechanism, and the second position on the conveyor belt 112 corresponds to the second transfer mechanism, wherein the first transfer mechanism can receive the stator hairpin 20 falling from the first position of the conveyor belt 112, and the second transfer mechanism can receive the stator hairpin 20 falling from the second position of the conveyor belt 112. The production equipment for producing stator hairpins 20 can be used to produce various types of stator hairpins 20. For example, the specifications of the stator hairpins 20 produced by the production equipment include a first specification and a second specification. The stator hairpins 20 of the first specification correspond to the first transfer mechanism, and the first transfer mechanism can transport the stator hairpins 20 of the first specification to the loading mechanism in the subsequent process. The stator hairpins 20 of the second specification correspond to the second transfer mechanism, and the second transfer mechanism can transport the stator hairpins 20 of the second specification to the loading mechanism in the subsequent process.

[0057] During the flat wire motor production process, after the production equipment produces the first specification of the formed stator hairpin 20, at least two stator hairpins 20 can be placed on the conveyor belt 112 of the conveyor assembly 11 in sequence. At this time, the conveyor assembly 11 is in an open state, and the conveyor belt 112 can drive the stator hairpin 20 to move along the extension direction E1 of the conveyor assembly 11 to convey the stator hairpin 20 in the direction close to the first transfer mechanism and the second transfer mechanism. The shifting assembly 13 can drive the two stator hairpins 20 according to the specifications of the stator hairpin 20 produced by the current production equipment. The ends of the two limiting ridges 121 move along the width direction of the conveying component 11 to move the ends of the two limiting ridges 121 to the first position of the conveyor belt 112. The guide component 12 can guide the stator hairpin 20 to the first position of the conveyor belt 112 so that the stator hairpin 20 is conveyed to the output end of the conveyor belt 112. The first transfer mechanism corresponding to the first position of the conveyor belt 112 can receive the stator hairpin 20 with the first specification and lift the stator hairpin 20 to a position where it can be grasped by the loading mechanism in the subsequent process.

[0058] It should be noted that in the embodiment of the present invention, the production personnel can also place at least two stator hairpins 20 on the conveyor belt 112 of the conveying component 11 in sequence; the shift component 13 can move according to the specification signal of the stator hairpin 20 sent by the production equipment, and the moving direction of the shift component 13 can also be controlled by the production personnel. The embodiment of the present invention does not limit this.

[0059] Please refer to Figure 1 and Figure 3In an optional embodiment, any transfer mechanism 14 may further include a drive unit 142, a mounting bracket 141, and a transmission belt 1431. The transmission belt 1431 is wound around the mounting bracket 141. A plurality of barriers 1432 are located on a side of the transmission belt 1431 facing away from the mounting bracket 141 and are fixedly connected to the transmission belt 1431. The barriers 1432 are arranged sequentially along the rotation direction of the transmission belt 1431. The stator hairpin 20 on the transfer mechanism 14 may be a U-shaped hairpin. The stator hairpin 20 on the transfer mechanism 14 may be mounted on the transmission belt 1431. The barriers 1432 enhance the stability of the stator hairpin 20 on the transmission belt 1431 and prevent it from slipping off the timing belt. Furthermore, each time the transmission belt 1431 receives a stator hairpin 20, the drive unit 142 drives the transmission belt 1431 to rotate a predetermined distance, which is the distance between two adjacent barriers 1432.

[0060] The mounting bracket 141 includes a bracket portion 1411, a first pulley 1412, a second pulley 1413, a third pulley 1414 and a fourth pulley 1415. The bracket portion 1411 has four corners. The first pulley 1412, the second pulley 1413, the third pulley 1414 and the fourth pulley 1415 are respectively installed at the four corners of the bracket portion 1411; the first pulley 1412, the second pulley 1413, the third pulley 1414 and the fourth pulley 1415 are all movably connected to the transmission belt 1431, and the first pulley 1412 is connected to the drive unit 142. In this way, a quadrilateral lifting structure can be formed, the driving unit 142 can be a driving motor, the first pulley 1412 is the driving pulley, the second pulley 1413, the third pulley 1414 and the fourth pulley 1415 are driven pulleys, and in the process of the lifting structure transporting the stator hairpin 20, the driving unit 142 can drive the first pulley 1412 to rotate, so as to drive the transmission belt 1431 and the second pulley 1413, the third pulley 1414 and the fourth pulley 1415 to rotate, and the stator hairpin 20 can fall from the conveyor belt 112 into the transmission belt 1431, so that the rotating transmission belt 1431 drives the stator hairpin 20 to lift.

[0061] Please refer to Figure 2 and Figure 4 , Figure 4This is a structural schematic diagram of a limiting ridge 121 provided in an embodiment of the present invention. In an optional embodiment, the guide assembly 12 may include two relatively arranged limiting ridges 121, and any one of the limiting ridges 121 includes a first connecting rod 1211, a second connecting rod 1212 and a third connecting rod 1213 connected in sequence; the first connecting rod 1211 can be fixedly connected to the support base 111, and the two ends of the second connecting rod 1212 are movably connected to the first connecting rod 1211 and the third connecting rod 1213 respectively, and the third connecting rod 1213 is connected to the shift assembly 13; the length direction of the first connecting rod 1211 and the length direction of the third connecting rod 1213 are both parallel to the extension direction E1 of the conveying assembly 11, and the shortest distance between the two second connecting rods 1212 of the two relatively arranged limiting ridges 121 gradually decreases along the extension direction E1 of the conveying assembly 11. The two first connecting rods 1211 in the guide assembly 12 can be arranged opposite to each other, the two second connecting rods 1212 in the guide assembly 12 can be arranged opposite to each other, and the two third connecting rods 1213 in the guide assembly 12 can be arranged opposite to each other, and the stator hairpin 20 can be located between the two limiting ridges 121. By providing the guide assembly 12, the stator hairpin 20 can be accurately guided to the corresponding transfer mechanism 14 and can also be prevented from being separated from the conveyor belt 112.

[0062] Moreover, since the shortest distance between the two first connecting rods 1211 is greater than the shortest distance between the two third connecting rods 1213, the shortest distance between the two second connecting rods 1212 of the two relatively arranged limiting ridges 121 gradually decreases along the extension direction E1 of the conveying component 11. The stator hairpin 20 can be a U-shaped hairpin, and the posture of the stator hairpin 20 can be corrected through the gap between the two limiting ridges 121, so that the length direction of the stator hairpin 20 can be parallel to the extension direction E1 of the conveying component 11, so that the transfer mechanism 14 can receive the stator hairpin 20 with the correct posture, so that the stator hairpin 20 can be mounted on the transmission belt 1431 of the transfer mechanism 14 after falling to the transfer mechanism 14, thereby preventing the stator hairpin 20 from being unable to fall stably on the transfer mechanism 14.

[0063] It should be noted that the U-shaped stator hairpin in the embodiment of the present invention includes: a first long leg, a second long leg, and a connecting bar, wherein the ends of the connecting bar are respectively connected to the first long leg and the second long leg. During the production process of the flat wire motor, the flat wire insertion device can insert the first and second long legs of the U-shaped stator hairpin into the stator slot. The length direction of the first long leg is parallel to the length direction of the second long leg, and the length direction of the first long leg and the length direction of the second long leg are the length direction of the stator hairpin.

[0064] Please refer to Figure 2 and Figure 4In an optional embodiment, any one of the limiting ridges 121 may also include a first pin 1214 and a second pin 1215; the first connecting rod 1211 has a first connecting through hole at one end close to the second connecting rod 1212, and the second connecting rod 1212 has a second connecting through hole corresponding to the first connecting through hole at one end close to the first connecting rod 1211, and the first pin 1214 is passed through the first connecting through hole and the second connecting through hole; the first pin 1214 can be movably connected to the first connecting rod 1211 and the second connecting rod 1212 respectively, so that the second connecting rod 1212 can rotate around the first pin 1214 relative to the first connecting rod 1211. Exemplarily, the first connecting rod 1211 may have a first connecting groove at one end close to the second connecting rod 1212, the first connecting groove having two opposite groove walls, both groove walls having a first connecting through hole, the second connecting rod 1212 may have a first protrusion at one end close to the first connecting rod 1211, the first protrusion having a second connecting through hole, the first protrusion of the second connecting rod 1212 may be located in the first connecting groove of the first connecting rod 1211, so that the two first connecting through holes are respectively located at both ends of the second connecting through hole, and the two first connecting through holes and the second connecting through hole may pass through in the length direction of the first pin 1214.

[0065] The second connecting rod 1212 has a third connecting hole at one end near the third connecting rod 1213, and the third connecting rod 1213 has a fourth connecting hole corresponding to the third connecting hole at one end near the second connecting rod 1212. The second pin 1215 is inserted into the third and fourth connecting holes. The connection method between the second connecting rod 1212 and the third connecting rod 1213 can be the same or similar to the connection method between the second connecting rod 1212 and the first connecting rod 1211, and this embodiment of the utility model will not be described in detail.

[0066] In the embodiment of the present invention, the first connecting rod 1211 can be connected to the support base 111 in the following two ways:

[0067] Method 1, please refer to Figure 2 and Figure 4Any limiting ridge 121 may further include a third pin 1216 and a fourth pin 1217; the first connecting rod 1211 has a strip-shaped through hole k1, and the length direction of the strip-shaped through hole k1 is parallel to the length direction of the first connecting rod 1211; the third pin 1216 and the fourth pin 1217 are both inserted into the strip-shaped through hole k1, and the end of the third pin 1216 and the end of the fourth pin 1217 are both fixedly connected to the support base 111, and the third pin 1216 and the fourth pin 1217 are arranged along the length direction of the strip-shaped through hole k1. In this way, the first connecting rod 1211 can be fixed to the support base 111 by the third pin 1216 and the fourth pin 1217 to prevent the first connecting rod 1211 from rotating. In addition, by accommodating the third pin 1216 and the fourth pin 1217 through the strip-shaped through hole k1 on the first connecting rod 1211, the installation accuracy of installing the limiting protrusion 121 on the support base 111 can be reduced to reduce the difficulty of installation.

The slider 1321 on the sliding module 132 can reciprocate along the width direction E2 of the conveyor assembly 11, thereby driving the connecting member 133 to move in the width direction E2 of the conveyor assembly 11, and further driving the third connecting rods to move in the width direction E2 of the conveyor assembly 11 via the connecting belt. The sliding module 132 may further include structures such as a servo motor, a linear guide rail, and a lead screw. The slider 1321 may be mounted on the linear guide rail and the lead screw. The servo motor may drive the lead screw to rotate, thereby driving the slider 1321 to slide on the linear guide rail through the lead screw.

[0070] Please refer to Figure 2 In an alternative embodiment, the connector 133 may include a connecting plate 1331, a first connecting rod 1332, and a second connecting rod 1333. The connecting plate 1331 is fixedly connected to the slider 1321 of the sliding module 132. The two ends of the first connecting rod 1332 are respectively connected to the connecting plate 1331 and one of the third connecting rods 1213 in the guide assembly 12. The two ends of the second connecting rod 1333 are respectively connected to the connecting plate 1331 and another of the third connecting rods 1213 in the guide assembly 12. By connecting the first connecting rod 1332 and the second connecting rod 1333 to the two third connecting rods 1213, respectively, the connector 133 can be prevented from interfering with the movement of the stator hairpin 20.
