Description

Technical Field

[0001] The utility model relates to the technical field of wire laying equipment, in particular to a flat wire wire laying device. Background Art

[0002] A motor with a stator winding using a rectangular cross-section wire is called a flat wire motor (also called a Pin motor). Different from a common wound motor, a flat wire motor does not first wind a round wire into a specific coil and then embed it into the stator slot by a machine. Instead, the flat wire (also called copper wire or flat copper wire, hereinafter collectively referred to as flat wire for unified technical terms) is preformed, inserted into the stator slot, and then formed and welded again at one or both ends to form the entire stator winding. The flat wire is beneficial to improving the slot fill factor of the motor. Generally, the slot fill factor of a round wire motor is about 50%, while that of a flat wire motor can reach more than 70%. According to the winding form of the flat wire motor, it can be further divided into Hair-pin winding (also called hairpin winding), I-Pin winding (also called I-type clip winding), wave winding, etc. The hairpin-type flat wire winding gets its name because its shape is more like a hairpin. Its advantage is that only one end needs to be welded, and its disadvantage is that the preparation is relatively complex. After the hairpin is formed, the hairpin wires are inserted into the stator core in groups, and finally assembled into a finished motor stator through equipment such as flaring, twisting, welding, and dipping in paint. The process of the hairpin forming machine mainly includes unwinding, peeling, fixed-length cutting, and hairpin forming. Currently, the existing unwinding device includes a frame, an expansion shaft, and a guiding wheel. The coil material is placed on the expansion shaft by a forklift, supported on the frame by the expansion shaft, and the expansion shaft is connected to a motor and can rotate relative to the frame. Since the coil material has a large self-weight and is placed on the expansion shaft of the frame as a whole, the loading and unloading are inconvenient, and there is a safety hazard of falling due to the excessive weight of the coil material.

[0026] Such as Figures 1 to 3As shown, the flat wire unwinding device 100 provided in this embodiment includes a frame 10 having an outlet end 10a, an unwinding mechanism 20 for placing a coil 200 composed of a bobbin 201 and a flat wire wound thereon (not shown in the figure), and a wire guiding mechanism 30 supported on the frame 10 and used to guide the flat wire to the outlet end 10a; the unwinding mechanism 20 includes: a base 21, located below the wire guiding mechanism 30; a support assembly 22, including two support shafts 221, 222 respectively used to abut against the outer edge of the bobbin 201, the axes of the two support shafts 221, 222 are parallel to each other and are spaced apart in the length direction of the frame 10, and each support shaft 221, 222 is rotatably supported on the base 21 and can rotate relative to the base 21 around the axis of the support shaft 221, 222; and a driving assembly 23, capable of driving at least one of the two support shafts 221, 222 to rotate.

[0027] For the above flat wire unwinding device 100, the coil 200 placed on the two support shafts 221, 222 of the support assembly 22 is supported. The driving assembly 23 is operated to rotate the support shafts 221, 222 to realize the unwinding of the coil 200. In this way, the coil 200 can be directly placed on or removed from the support shafts 221, 222, which is convenient for loading and unloading. At the same time, the risk of falling off the support shafts 221, 222 due to excessive self-weight is avoided, and the overall structure is more concise.

[0028] See Figures 1 to 3 Referring to, the flat wire unwinding device 100 provided in this embodiment includes a frame 10, an unwinding mechanism 20, and a wire guiding mechanism 30. The frame 10 has a length direction D1 (the D1 direction in the figure, hereinafter collectively referred to as the length direction D1) and a width direction D2 (the D2 direction in the figure, hereinafter collectively referred to as the width direction D2). The wire guiding mechanism 30 is supported on the frame 10, and the unwinding mechanism 20 is independently arranged and located below the unwinding mechanism 20.

[0029] See Figures 1 to 3, the wire pay-off mechanism 20 provided in this embodiment is used to place the coil 200, and the coil 200 includes a bobbin 201 and flat wires wound thereon. The wire pay-off mechanism 20 includes a base 21, a support assembly 22 and a drive assembly 23. The base 21 can be connected to the frame 10 or can be provided independently of the frame 10. In this embodiment, the base 21 is independent of the frame 10 and is provided at the bottom of the frame 10. Both the support assembly 22 and the drive assembly 23 are mounted on the base 21. The support assembly 22 includes two support shafts 221 and 222 whose axes are parallel to each other. The support shafts 221 and 222 extend along the width direction D2 of the frame 10 and are spaced apart in the length direction D1 of the frame 10. Each of the support shafts 221 and 222 is rotatably supported on the base 21 through a bearing block 223 and can rotate relative to the base 21 about the axis of the support shafts 221 and 222. The length dimension of the support shafts 221 and 222 is at least longer than the length dimension of the bobbin 201. The support shafts 221 and 222 abut against the outer edge of the bobbin 201 and rotatably support the bobbin 201 on the two support shafts 221 and 222. The drive assembly 23 can drive the support shafts 221 and 222 to rotate so as to drive the coil 200 to rotate about the axis of the bobbin 201. It can be understood that the wire pay-off mechanism 20 can supply flat wires, place the coil 200 between the two support shafts 221 and 222 in such a way that the axis of the bobbin 201 is parallel to the axes of the support shafts 221 and 222. The coil 200 abuts against the two support shafts 221 and 222 respectively by its own weight. By the drive assembly 23, the support shafts 221 and 222 rotate about the axes of the support shafts 221 and 222, thereby driving the coil 200 to rotate to achieve wire pay-off in an active manner.

[0030] See Figures 1 to 3 , the two support shafts 221 and 222 provided in this embodiment are divided into a first support shaft 221 and a second support shaft 222. The first support shaft 221 is connected to the drive assembly 23 and is driven to rotate by the drive assembly 23.

[0031] In other embodiments, the drive assembly 23 can be respectively connected to the two support shafts 221 and 222 and drive the two support shafts 221 and 222 to rotate simultaneously.

[0032] See Figures 1 to 4, a coupling component 24 is provided on the base 21 provided in this embodiment; the coupling component 24 includes: a bushing 241, rotatably supported on the base 21, the bushing 241 is connected to the drive component 23 and is driven by the drive component 23 to rotate relative to the base 21 about the axis of the bushing 241; a shaft body 242, disposed within the bushing 241, both ends of the shaft body 242 respectively extend outside the bushing 241 and form a hinged end 242a and a free end 242b; and a coupling power member 243, capable of driving the shaft body 242 to move axially within the bushing 241; the hinged end 242a of the shaft body 242 is hinged to the coupling power member 243, and a first anti-rotation structure 244 is provided between the free end 242b of the shaft body 242 and the end of the first support shaft 221 to prevent relative rotation between the two; a second anti-rotation structure 245 is provided between the shaft body 242 and the bushing 241 to prevent relative rotation between the two. In this embodiment, the coupling component 24 and the first support shaft 221 are detachably connected. The coupling component 24 includes a bushing 241, a shaft body 242, a coupling mounting seat 246, and a coupling power member 243. The coupling mounting seat 246 and the coupling power member 243 are respectively fixed on the base 21 and supported by the base 21. The coupling power member 243 is but not limited to a cylinder. The coupling mounting seat 246 and the coupling power member 243 are spaced apart in the width direction D2 of the frame 10. The bushing 241 and the shaft body 242 respectively extend along the width direction D2 of the frame 10. The length dimension of the shaft body 242 is larger than the length dimension of the shaft body 242. The bushing 241 is sleeved outside the shaft body 242. The bushing 241 is rotatably supported on the coupling mounting seat 246 through a bearing 247. The shaft body 242 can move relative to the bushing 241 along its axis, and relative rotation between the two is not allowed. The hinged end 242a of the shaft body 242 is connected to the output shaft of the coupling power member 243 through a hinge head 248. When the output shaft moves, the shaft body 242 can be driven to move. When the drive component 23 drives the bushing 241 to drive the shaft body 242 to rotate, the bushing 241 and the shaft body 242 can rotate relative to the output shaft. The free end 242b of the shaft body 242 can contact and separate from the first support shaft 221 under the control of the output shaft. When the two are connected, relative rotation between the two is prevented through the first anti-rotation structure 244.It should be noted that with the above-mentioned connection component 24, before unwinding the coil 200, the shaft body 242 can be controlled to separate from the first support shaft 221. After the coil 200 is placed on the support component 22, an operator can manually pull the flat wire through the wire guiding mechanism 30 to the wire outlet end 10a, and it can be sent into a wire feeding device (not shown in the figure) in the next process for clamping by the wire feeding device. Then, the free end 242b of the shaft body 242 is controlled by the connection power member 243 to be docked with the end of the first support shaft 221, and then the driving component 23 is driven to rotate the first support shaft 221 to rotate the coil 200. In this way, the wire feeding of the flat wire can have two methods: active wire unwinding and passive wire unwinding. One is that the flat wire can be pulled to move by the wire feeding device, and the other is that the coil 200 can be rotated by the rotation of the first support shaft 221 to achieve wire feeding.

[0033] See Figures 1 to 4 , in this embodiment, a slot 2211 for the free end 242b to move in and out is formed on the end face of the first support shaft 221. A rotation prevention groove 2212 is formed on the groove wall of the slot 2211. The rotation prevention groove 2212 extends from the groove wall of the slot 2211 along the axial direction of the first support shaft 221 to the end face of the first support shaft 221 near the shaft sleeve 241. The first rotation prevention structure 244 includes a rotation prevention pin 2441 installed on the free end 242b and capable of engaging with the rotation prevention groove 2212. The rotation prevention pin 2441 penetrates through the shaft body 242. In this way, when the free end 242b of the shaft body 242 is docked with the first support shaft 221, the free end 242b moves into the slot 2211, and at the same time, the rotation prevention pin 2441 moves into the corresponding rotation prevention groove 2212. The relative rotation of the shaft body 242 and the first support shaft 221 is restricted by the cooperation of the rotation prevention pin 2441 and the rotation prevention groove 2212.

[0034] In other embodiments, the shaft body 242 and the first support shaft 221 can also be connected by a key pin, or by a non-circular cross-section connection.

[0035] See Figures 1 to 4 , in this embodiment, a long slot 2411 extending along its axial direction is formed on the shaft sleeve 241. The second rotation prevention structure 245 includes a rotation prevention shaft 2451 installed on the shaft body 242 and extending to the outside of the shaft body 242 at its end. The end of the rotation prevention shaft 2451 is slidably arranged in the long slot 2411.

[0036] In other embodiments, the shaft body 242 and the shaft sleeve 241 can also be connected by a key pin, or by a non-circular cross-section connection.

[0037] See Figure 2, the driving component 23 provided in this embodiment includes a motor 231 supported on the base 21, a main synchronous pulley 232 mounted on the motor 231, a slave synchronous pulley 233 mounted on the bushing 241, and a synchronous belt 234 connecting the main synchronous pulley 232 and the slave synchronous pulley 233. The bushing 241 connected to the slave synchronous pulley 233 is driven to rotate by the motor 231, so as to drive the shaft body 242 and the first support shaft 221 to rotate, thereby rotating the coiled material 200 to achieve active wire pay-off.

[0038] See Figures 1 to 3 , the wire guiding mechanism 30 provided in this embodiment is used to guide the flat wire to the wire outlet end 10a. In this embodiment, the wire guiding mechanism 30 includes a tensioning component 31 and a wire guiding wheel 32 respectively supported on the frame 10. The number of wire guiding wheels 32 is one but not limited to one. The wire pay-off mechanism 20 is located below the tensioning component 31. The wire guiding wheel 32 is located between the tensioning component 31 and the wire outlet end 10a in the length direction D1 of the frame 10. In this way, the flat wire passes around the wire guiding wheel 32 and the tensioning component 31 and then reaches the wire outlet end 10a of the frame 10, and the overall structure is more compact, the size is smaller, and space is saved.

[0039] See Figures 1 to 3 , the tensioning component 31 provided in this embodiment includes a tensioning wheel 311 for abutting against the flat wire and movable along the length direction D1 of the frame 10, and a tensioning power component 312 capable of driving the tensioning wheel 311 to move. In this embodiment, two slide rails 313 are installed on the frame 10 along the length direction D1 of the frame 10. A tensioning bracket 314 is arranged on the frame 10, and the tensioning bracket 314 is slidably installed on the slide rails 313. The tensioning wheel 311 is rotatably supported on the tensioning bracket 314. The tensioning power component 312 is one but not limited to a rodless cylinder. The rodless cylinder includes a cylinder body fixed on the frame 10 and a slider 3121 movably connected to the cylinder body and movable along the axial direction of the cylinder body. The tensioning wheel 311 is connected to the slider 3121 through the tensioning bracket 314. In this way, driven by the tensioning power component 312, the tensioning wheel 311 can reciprocate in the length direction D1 of the frame 10. It should be noted that with the above structure, when the stretching amount of the flat wire is too large, the tensioning wheel 311 can be controlled to move towards the wire outlet end 10a, and when the stretching amount is too small, the tensioning wheel 311 can be controlled to move in the direction away from the wire outlet end 10a. In this way, a certain tension of the flat wire can be ensured, and the wire feeding position can be ensured to be accurate.

[0040] See Figures 1 to 3, a pressing and holding component 40 is provided on the frame 10 provided in this embodiment. The pressing and holding component 40 includes a pressing wheel 41 that is liftably mounted on the frame 10 and a pressing power member 42 for driving the pressing wheel 41 to move downward and pressing the cartridge 201 against the supporting component 22. The pressing power member 42 is, but not limited to, a cylinder, which is fixedly mounted on the frame 10 and located on one side of the tensioning component 31. It can be understood that as the flat wire on the coiled material 200 decreases, the weight of the coiled material 200 will decrease accordingly, and it is easy for the cartridge 201 to fall off when pulling the flat wire. Therefore, the pressing wheel 41 of the above pressing and holding component 40 moves downward to press the cartridge 201 against the supporting component 22, thereby effectively preventing the cartridge 201 from falling off.

[0041] See Figures 1 to 3 , a straightening component 50 is provided on the frame 10 provided in this embodiment. The straightening component 50 is located between the wire guiding mechanism 30 and the wire outlet end 10a. The straightening component 50 is any existing straightening component in the prior art that can achieve straightening.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
