Description

Technical Field

[0001] The invention relates to the technical field of motor stators, and in particular to a copper wire winding taking and placing device. Background Art

[0002] As motors are widely used in various fields, the demand for motors is increasing day by day, and the stator, as a key component of the motor, is in even greater demand. In the existing flat copper wire motor stator production process, there are generally two ways to form flat copper wires: the first is that all flat copper wires are twisted and formed together in the tooling; the second is that a single copper wire is formed. However, regardless of the wire making method, if the copper wire is to be inserted into the iron core in an automated manner, the copper wire winding needs to be clamped and placed, and the copper wire winding needs to be clamped out of the twisting and forming tooling. The copper wire winding picking and placing device on the existing automatic wire twisting machine adopts a circle of wire taking pieces to clamp the copper wire winding. Therefore, if the wire twisting forming tooling pushes the copper wire winding too high, the copper wire winding will be too far away from the wire twisting forming tooling, the limit range will become shorter, and the copper wire will be easily skewed, resulting in the wire taking piece being unable to be normally inserted into the copper wire winding for clamping. Therefore, the wire twisting forming tooling cannot push the copper wire winding too high. However, in this way, the lower overhanging part of the copper wire winding is longer when clamping, and the copper wire winding is prone to deformation. There is a certain probability of wire jamming risk, which is not conducive to the introduction of the lower part of the copper wire winding into the iron core. Summary of the invention

[0033] An embodiment of the copper wire winding pick-up and placement device of the present invention:

[0034] See also Figure 1-Figure 10, a copper wire winding pick-up and placement device, comprising an upper cover plate 1, a middle fixed plate 2, a lower fixed plate 3, a centering column 4, a plurality of first clamping strips 5 and a second clamping strip 6, and a first driving disk 7 and a second driving disk 8 for driving the first clamping strip 5 and the second clamping strip 6 to move respectively, the upper cover plate 1, the middle fixed plate 2, and the lower fixed plate 3 are stacked and fixedly connected in sequence from top to bottom, the middle fixed plate 2 and the lower fixed plate 3 are both provided with a circular groove 9, the groove bottom center of the circular groove is provided with a clearance hole 10 for making way for the copper wire winding, the upper end surface of the groove bottom is uniformly provided with a plurality of radially extending guide grooves 11 around the center of the circle, the groove bottom of the circular groove 9 is uniformly provided with a plurality of upwardly extending bosses 20 around the clearance hole 10, the bosses 20 are radially distributed, and a spacing is left between each boss 20 to form a guide groove 11, the boss 20 is wedge-shaped, and the upper end surface of each boss 20 is located in the same horizontal plane. A first clamping strip 5 is slidably fitted in each guide groove 11 on the middle fixed plate 2, and a second clamping strip 6 is slidably fitted in each guide groove 11 on the lower fixed plate 3. An upwardly extending guide pin 13 is provided on the bar portion 12 of the first clamping strip 5 and the second clamping strip 6. The guide pin 13 is a cylindrical pin, and the guide pin 13 is fixed to the mounting hole 22 provided on the bar portion 12 by interference fit. The bar portion 12 is located at one end of the clearance hole 10 and is provided with a clamping portion 14. The clamping portion 14 is U-shaped and opens toward the center of the circle. The bar portion 12 of each clamping bar slides in the guide groove 11, and the clamping portion 14 extends out of the guide groove 11. The first driving disk 7 and the second driving disk 8 are both annular in shape with a center hole 15 for clearance. A plurality of strip holes 16 are evenly distributed along the ring on each driving disk. The long axis of each strip hole 16 is oblique to the radius of the ring. The first driving disk 7 slides in the circular groove of the middle fixing plate 2, so that the guide pins 13 on each first clamping bar 5 are respectively inserted into each strip hole 16, and do not extend. The strip hole 16 is extended outward, and the second driving disk 8 is slidably matched in the circular groove of the lower fixed plate 3, so that the guide pins 13 on each second clamping strip 6 are respectively inserted into each strip hole 16 without extending out of the strip hole 16. The upper surface of the first driving disk 7 is slightly lower than the upper surface of the middle fixed plate 2, and the upper surface of the second driving disk 8 is slightly lower than the upper surface of the lower fixed plate 3. One side of the first driving disk 7 and the second driving disk 8 is provided with a force arm 17 extending outward. The force arms 17 of the first driving disk 7 and the second driving disk 8 are each hinged to the piston rod of a driving cylinder 21, so that the driving cylinder 21 can drive the first driving disk 7 and the second driving disk 8 to rotate.The sides of the middle fixing plate 2 and the lower fixing plate 3 are provided with clearance openings 18 for the force arm 17 to extend outward, and the clearance openings 18 leave the freedom of movement of the force arm 17. By applying force to the force arm, each driving disk can rotate in the circular groove. The clearance openings 18 on the sides of the middle fixing plate 2 and the lower fixing plate 3 are located on different sides to avoid position interference of the two driving cylinders 21; the centering column 4 is located at the center of the clearance hole 10 of the middle fixing plate 2 and the lower fixing plate 3, and is clamped with the first clamping bar 5 and the second clamping bar 6. The position spacing of the copper wire winding 19 is reserved between the parts 14. The centering column 4 and the upper cover plate 1 are used to connect the automatic twisting machine. The centering column 4 is fixedly connected to the automatic twisting machine through the connecting block 23. The setting of the centering column 4 prevents the copper wire winding 19 from being squeezed and deformed while being clamped by each clamping bar. The outer periphery of the centering column 4 is provided with a plurality of teeth for inserting into the gaps on the copper wire winding 19. The number of teeth is consistent with the number of gaps on the copper wire winding 19, so as to cooperate with each clamping bar to clamp the copper wire winding 19. The upper cover plate 1 is provided with a through hole to give way to the centering column 4. The number of strip holes 16 on the first drive disk 7 corresponds to the number of the first clamping bar 5, and the number of strip holes 16 on the second drive disk 8 corresponds to the number of the second clamping bar 6. The copper wire winding in this embodiment is composed of 96 groups of wires and has 96 gaps. Correspondingly, the first clamping strip and the second clamping strip each have 48, and the first drive disk and the second drive disk each have 48 bar holes. The radial movement of each clamping strip can be controlled by rotating the first drive disk 7 and the second drive disk 8. At the same time, the inner ring of the copper wire winding 19 is pressed by the centering column 4, so that the copper wire winding 19 can be clamped and placed. In such a copper wire winding placement device, the clamping strip can be accurately inserted into the gap of the copper wire winding, the twisting wire forming tool can push the copper wire winding higher, and the copper wire is not easy to be skewed. The clamping and placement can be performed when the lower overhang of the copper wire winding is extremely short. Since the overhang part of the lower part of the copper wire winding is short, the overhang part is not easy to deform, and the lower part of the copper wire winding can be smoothly introduced into the iron core.

[0035] When clamping the copper wire winding, the device first moves to the top of the copper wire winding with the automatic wire twisting machine, and then descends so that the copper wire winding 19 is located in the middle position of the device. The copper wire winding 19 is pushed up by the wire twisting forming tooling to between the centering column 4 and the makeshift holes 10 of the middle fixed plate 2 and the lower fixed plate 3. Then, the second driving disk 8 is driven to rotate by the driving cylinder, and the strip holes 16 on the second driving disk 8 move accordingly, so that the guide pins 13 on the second clamping strips 6 slide in the strip holes 16, driving all the second clamping strips 6 to move toward the center of the circle and insert into the gaps of the copper wire windings, so that the copper wire cannot be displaced and the copper wire will not be skewed. After that, the copper wire winding 19 is lifted up again by the wire twisting forming tooling, and the length of the copper wire winding 19 remaining in the wire twisting forming tooling is greatly shortened. Then, the first driving disk 7 is driven The pneumatic cylinder drives the rotation, and the strip hole 16 on the first driving disk 7 moves accordingly, so that the guide pin 13 on the first clamping strip 5 slides in the strip hole 16, driving all the first clamping strips 5 to move toward the center of the circle and insert into the gap of the copper wire winding. At this time, the copper wire winding is completely fixed and clamped, and the centering column 4 also rests against the inner circle of the copper wire winding 19, and cooperates with each clamping strip to completely remove the copper wire winding 19 from the twisting forming tooling and transfer it to other places. To release the copper wire winding 19, it is only necessary to let the two driving cylinders drive the first driving disk 7 and the second driving disk 8 respectively to rotate in the opposite direction, so that the first clamping strip 5 and the second clamping strip 6 move away from the center of the circle, and release the clamping of the copper wire winding 19. Finally, the device rises with the automatic wire twisting machine to separate the centering column 4 from the inner circle of the copper wire winding 19.
