In the description of the utility model, the meaning of "a plurality of" is two or more, unless otherwise specified.
[0037] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.
[0038] Reference is made to the drawings Figures 1-6 The embodiment provides a kind of equipment for removing the stator winding in flat wire motor, it includes rack 1, stator seat 2, take-up box 3, first horizontal moving module 4, cut wire assembly 5, press wire assembly 8 and numerical controller 9, rack 1 includes base 1.1, stand 1.2 and top frame 1.3, base 1.1 is cuboid box structure, take-up box 3 is located in its interior, the top end of take-up box 3 is opened, and opening is through the outside of base 1.1, to facilitate receiving the stator winding removed, stand 1.2 is configured on the top of base 1.1, for supporting top frame 1.3, for stator seat 2, first horizontal moving module 4 and the removed piece provide placement and movement space, top frame 1.3 is used to fix cut wire assembly 5, press wire assembly 8 and numerical controller 9, numerical controller 9 is used to control any electrical component in the equipment, including first horizontal moving module 4, cut wire assembly 5, press wire assembly 8 and other electrical components possibly mentioned below;Cut wire assembly 5 and press wire assembly 8 are transversely arranged above take-up box 3, stator seat 2 is connected with first horizontal moving module 4, and is driven to move between cut wire assembly 5 and press wire assembly 8.
[0039] When separating the stator core and the stator winding by using the above device, the stator is placed on the stator seat 2, the two ends of the stator winding are cut by the wire cutting assembly 5, the ends are separated from the copper wire in the middle part and fall into the wire collecting box 3, the stator with the cut ends is moved to the lower side of the wire pressing assembly 8 by the first horizontal moving module 4, the copper wire in the stator core is pressed out by the wire pressing assembly 8 and falls into the wire collecting box 3.
[0040] After the ends are cut from the stator, they can be manually taken into the wire collecting box 3, or the stator seat 2 can be specially designed and a structure for pushing and sweeping the ends is added above the stator seat 2 to increase the degree of automation of the equipment, reduce manual participation and reduce the probability of misoperation or injury. As for the special design of the stator seat 2 and the structure for pushing and sweeping the ends added above the stator seat 2, they can be added separately or simultaneously, which can be determined according to user needs.
[0041] When the stator seat 2 is specially designed, the first falling hole 2.1 can be arranged in the stator seat 2, and the second falling hole 3.1 is opened at the top end of the falling box. The length direction of the second falling hole 3.1 is the same as the moving direction of the stator seat 2, the outer diameter of the stator winding is less than the diameter of the first falling hole 2.1, and the outer diameter of the stator core is less than the diameter of the first falling hole 2.1. When the ends are cut from the stator, the ends originally located below the stator core can directly pass through the first falling hole 2.1 and the second falling hole 3.1 and fall into the wire collecting box 3, and the copper wire pressed out by the wire pressing assembly 8 can also be collected in this way.
[0042] When the structure for pushing and sweeping the ends is added above the stator seat 2, the door frame 10 and the wire sweeping brush 11 can be arranged at the top of the base 1.1. The door frame 10 is located between the wire cutting assembly 5 and the wire pressing assembly 8 and is arranged at both ends outside the first horizontal moving module 4 to avoid affecting the movement of the stator seat 2. The wire sweeping brush 11 is arranged below the top beam of the door frame 10 and is used to push and sweep the ends originally located above the stator core. When the first horizontal moving module 4 moves the stator seat 2 to the lower side of the door frame 10, the wire sweeping brush 11 fixedly arranged can push the ends laterally and separate them from the stator core, and then the ends pass through the top opening of the wire collecting box 3 and fall into the wire collecting box 3.
[0043] When one of the above two ways is designed separately, the wire cutting work can be performed on one end of the stator core at a time, and after the work is completed, the stator is manually turned over for wire cutting work on the other side. When both are designed at the same time, the wire cutting work can be performed on both ends of the stator core at the same time, which not only reduces the accidents caused by manual participation, but also greatly improves the work efficiency.
[0044] In addition, the stator seat 2 can also be configured with various grooves, protrusions and the like for limiting according to the actual shape of the stator, which is a routine design that can be made by those skilled in the art, and will not be described here.
[0045] In this embodiment, the wire cutting assembly 5 includes a first lifting module 5.1, a rotating module 5.2, a stator clamping jaw 5.3, and a wire cutter 5.4. The rotating module 5.2 is connected to the first lifting module 5.1 and is driven to lift by the first lifting module 5.1. The stator clamping jaw 5.3 is connected to the rotating module 5.2 and is driven to rotate around its own axis. The wire cutter 5.4 is arranged on the circumferential outer side of the stator clamping jaw 5.3 and is used to cut the end of the stator winding. Since the stator clamping jaw 5.3 is connected to the rotating module 5.2, the first lifting module 5.1 can not only lift the rotating module 5.2, but also lift the stator clamping jaw 5.3. In use, the stator clamping jaw 5.3 clamps the stator on the stator seat 2, the first lifting module 5.1 lifts the stator clamping jaw 5.3 and the stator to the height of the wire cutter 5.4, the wire cutter 5.4 is started to cut the connection between the straight copper wire and the end, since the copper wire is uniformly distributed around the stator core, the rotating module 5.2 is used to rotate the stator clamping jaw 5.3 and the stator during the operation of the wire cutter 5.4, so that the wire cutter 5.4 cuts all the copper wires, after the straight copper wire and the end are separated, the end at the bottom falls into the wire collecting box 3, the first lifting module 5.1 lowers the stator clamping jaw 5.3 and the stator with the end removed, so that the stator with the end removed falls on the stator seat 2, and then the first horizontal moving module 4 can be used to move it below the wire pressing assembly 8 to press and remove the straight copper wire.
[0046] In order to expand the universality of the device, the second horizontal moving module 6 is arranged on the rack 1, the wire cutter 5.4 is connected to the second horizontal moving module 6 and is driven to move along the radial direction of the stator seat 2. When the second horizontal moving module 6 operates, the distance between the wire cutter 5.4 and the stator seat 2 can be changed to meet the disassembly requirements of stators with different diameters.
[0047] In addition, the second lifting module 7 can also be arranged on the second horizontal moving module 6, and the wire cutter 5.4 is arranged on the second lifting module 7, so that the wire cutter 5.4 is driven to lift by the second lifting module 7. The second horizontal moving module 6 drives the second lifting module 7 and the wire cutter 5.4 to move together to meet the disassembly requirements of stators with different diameters, and the second lifting module 7 can lift the wire cutter 5.4 to meet the disassembly requirements of stators with different heights, or the wire cutter 5.4 can first cut the copper wire end at one end of the stator core and then move to the other end of the stator core for cutting.
[0048] In order to improve the working efficiency of the equipment, at least two height-different wire cutters 5.4 can be arranged on the circumferential outer side of the stator clamping jaw 5.3, and after the height of the two wire cutters 5.4 is adjusted by the second lifting module 7, the two wire cutters 5.4 are used to cut the copper wire end heads on the upper and lower ends of the stator core at the same time.
[0049] In the embodiment, the wire pressing assembly 8 comprises a third lifting module 8.1, a pressing block 8.2, a vertical pressing rod 8.3 and a stiff spring 8.4, the pressing block 8.2 is connected to the third lifting module 8.1 and is driven to ascend and descend by the third lifting module 8.1; a plurality of pressing rod sliding grooves 8.21 are arranged on the pressing block 8.2, the vertical pressing rod 8.3 is slidingly arranged in the pressing rod sliding groove 8.21, and a limiting block 8.5 with an outer diameter larger than the diameter of the pressing rod sliding groove 8.21 is arranged at the top end of the vertical pressing rod 8.3; the stiff spring 8.4 is sleeved on the vertical pressing rod 8.3, and the top end and the bottom end of the stiff spring 8.4 abut against the inner wall of the pressing rod sliding groove 8.21 and the limiting plate 8.6 located on the vertical pressing rod 8.3 respectively; a flexible pressing head 8.7 is arranged at the bottom end of the vertical pressing rod 8.3, and when the stiff spring 8.4 is naturally elongated, the bottom end of the flexible pressing head 8.7 extends out of the pressing block 8.2. When the stator after cutting off the end heads is moved to the lower side of the wire pressing assembly 8, the third lifting module 8.1 drives the pressing block 8.2 to quickly descend, so as to accurately press the stator and prevent the stator from being displaced in the process of pressing the wire; and in the process that the pressing block 8.2 descends and contacts the top of the stator, the flexible pressing head 8.7 and the vertical pressing rod 8.3 quickly slide upward, the limiting plate 8.6 extrudes the stiff spring 8.4, the stiff spring 8.4 stores energy and then slowly releases the energy, so as to press off the straight copper wire in the stator core.
[0050] Each of the horizontal moving module and the lifting module described above can be assembled by using the linear guide rail module, the servo motor 4.4 (or the air cylinder, the servo cylinder 5.12) and the like components commonly used in the field. The utility model only exemplarily shows some specific implementation schemes, but does not limit the protection scope of the utility model.
[0051] Reference is made to the accompanying drawings Figure 3The first horizontal moving module 4 comprises a first linear guide rail module 4.1, a transmission screw 4.2, a transmission screw block 4.3 and a servo motor 4.4. The first linear guide rail module 4.1 is arranged on both sides of the second blanking hole 3.1 in the width direction, wherein the linear guide rails extend along the length direction of the second blanking hole 3.1. The two groups of first linear guide rail modules 4.1 are used to ensure the stability of the movement of the stator seat 2. The transmission screw 4.2 is arranged on the outer side of the first linear guide rail module 4.1 in the same direction. The transmission screw block 4.3 is sleeved on the transmission screw 4.2 and slides against the base 1.1 (at least has a planar sliding abutment). The servo motor 4.4 is connected to one end of the transmission screw 4.2. The bottom end of the stator seat 2 is connected to the transmission screw block 4.3 and the sliding seat in the first linear guide rail module 4.1. When the servo motor 4.4 drives the transmission screw 4.2 to rotate, the transmission screw block 4.3 is limited by the sliding abutment of the base 1.1 and can only move along the axial direction of the transmission screw 4.2, and cannot rotate around the shaft, thereby realizing the pushing movement of the stator seat 2.
[0052] Reference is made to the accompanying drawings Figure 4 The second horizontal moving module 6 and the second lifting module 7 can be configured in the same way as the first horizontal moving module, and are arranged at different positions and in different directions according to the above description. Some conventional connecting plates, connecting seats and other components can be added between the second horizontal moving module 6 and the second lifting module 7, which are well known to those skilled in the art and will not be described here.
[0053] Reference is made to the accompanying drawings Figure 4 The first lifting module 5.1 comprises a second linear guide rail module 5.11, a servo cylinder 5.12, a guide rod 5.13, a sliding sleeve 5.14 and a follower frame 5.15. The linear guide rails in the second linear guide rail module 5.11 are arranged vertically on the top frame 1.3. The servo cylinder 5.12 is connected to the sliding seat in the second linear guide rail module 5.11. The guide rod 5.13 is arranged in at least two groups on the outer side of the linear guide rails in the same direction and parallel to each other, so as to ensure the stability of the lifting of the follower frame 5.15. The sliding sleeve 5.14 is arranged on the follower frame 5.15 and is sleeved on the guide rod 5.13. The follower frame 5.15 is used to install a rotating module 5.2 (which can be directly a servo motor 4.4). The rotating module 5.2 is connected to the stator jaw 5.3 below. When the piston rod of the servo cylinder 5.12 extends and retracts, the follower frame 5.15 rises and falls, thereby driving the stator jaw 5.3 to rise and fall.
[0054] Reference is made to the accompanying drawings Figure 6 The third lifting module 8.1 can be configured in the same way as the first lifting module 5.1. Since there is no rotating module 5.2 in the wire pressing assembly 8, the structure of the follower frame 5.15 can be adaptively simplified. In addition, some conventional connecting plates, connecting seats and other components can be added, which are well known to those skilled in the art and will not be described here.
[0055] Also as an example, the wire cutter 5.4 can adopt existing equipment such as pneumatic scissors, and the stator clamping jaw 5.3 can be assembled by a three-jaw pneumatic cylinder 5.31 and a pressing member 5.32 (see FIG. 5B, which is a schematic view of the stator clamping jaw 5.3 and the three-jaw pneumatic cylinder 5.31 and the pressing member 5.32 in the equipment for disassembling the stator winding of the flat wire motor according to the present application). Figure 5 Each gas jaw of the three-jaw pneumatic cylinder 5.31 is connected with a pressing member 5.32, and the pressing member 5.32 can be of any structure such as a rod or a block, and can be configured to press against the outer wall of the stator core or the inner wall of the stator core as the gas jaw extends or retracts, and no more specific limitation is made herein.
[0056] The use method of the equipment for disassembling the stator winding of the flat wire motor has been described in detail above, and no more description is made herein, and the beneficial effects at least include: through the cooperation of the wire cutting assembly 5, the wire pressing assembly 8 and the first horizontal moving module 4, the stator core and the stator winding can be separated with high mechanization, and the working efficiency is improved; through the cooperation of the specific stator base 2, the portal frame 10 and the wire sweeping brush 11, the mechanization degree of the equipment can be further improved, the probability of accidents caused by manual participation can be reduced, and the working efficiency of the equipment can be further improved.
[0057] The above is the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
