Description

Technical Field

[0001] The invention relates to the technical field of stator assembly, and in particular to a stator circle assembly device and a stator circle assembly method. Background Art

[0002] In the production process of the stator, in order to avoid mutual interference between adjacent windings, the spacing between adjacent windings is usually controlled, or insulating paper is used to separate two adjacent windings. Among them, the method of using insulating paper for isolation is usually for stators with a large number of winding turns and a close distance between two adjacent windings. In order to facilitate the pasting of insulating paper, the stator will be modularized and then reassembled. At present, the stator is mostly assembled manually, which not only has low assembly efficiency, but also is prone to errors, resulting in a high product defect rate. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a stator circle assembly device and a circle assembly method, which can ensure the assembly efficiency and circle assembly quality of the stator.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: A technical solution adopted by the present invention is: a stator circle assembly device, comprising at least two relatively movable circle assembly components, The circle assembly has an arc-shaped circle assembly station, and after each of the circle assembly is gathered together, the circle assembly station is enclosed to form a circle; The circle assembly includes two first jigs spaced apart and arranged on the circle station; Two second jigs are arranged at intervals on the rounding station, and the first jig and the second jig are alternately arranged on the rounding station; A turntable is connected to the first fixture.

[0005] In order to solve the above technical problems, another technical solution adopted by the present invention is: a circle splicing method, having two winding modules, and using the same wire for winding on the two winding modules to obtain a stator winding module; A plurality of the stator winding modules are combined to form a stator component unit, and one side of a winding module of the stator winding module is a winding module of another stator winding module; A plurality of the stator component units are combined to form a prototype of a stator; The stator undergoes a shaping process to connect adjacent winding modules.

[0006] The beneficial effect of the present invention is that: since the two first jigs and the two second jigs on the circular assembly are alternately arranged on the circular assembly station, the first jig and the second jig can prevent the winding modules on the same stator winding module from being adjacent. After the stator winding module is placed, the winding module on the first jig is driven close to the winding module on the second jig by rotating the turntable to form a stator component unit, and then each circular assembly is gathered together so that the stator component unit is combined into a stator prototype, and finally the adjacent winding modules are connected through a shaping process to obtain a stator.

[0008] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0009] Please refer to Figures 1 to 4As shown, a stator circle assembly device includes at least two relatively movable circle assembly components 1, the circle assembly components 1 have arc-shaped circle assembly stations, and after each of the circle assembly components 1 are gathered, the circle assembly stations are enclosed to form a circle; the circle assembly 1 includes two first jigs 11 spaced apart on the circle assembly stations; two second jigs 12 spaced apart on the circle assembly stations, and the first jigs 11 and the second jigs 12 are alternately arranged at the circle assembly stations; a turntable 13, and the turntable 13 is connected to the first jig 11.

[0010] Working principle: Since the two first jigs 11 and the two second jigs 12 on the circular assembly 1 are arranged alternately on the circular assembly station, the first jig 11 and the second jig 12 can prevent the winding modules 4 on the same stator winding module from being adjacent. After the stator winding module is placed, the turntable 13 is rotated to drive the winding module 4 on the first jig 11 close to the winding module 4 on the second jig 12 to form a stator component unit, and then each circular assembly 1 is gathered together to make the stator component unit form a stator prototype, and finally the adjacent winding modules are connected through the shaping process to obtain the stator.

[0011] It is worth mentioning that please refer to Figure 4 As shown, the circle assembly 1 includes a first driver 15, the output end of which is connected to the turntable 13 to drive the turntable 13 to rotate. Preferably, the first driver 15 is a cylinder, and the piston rod of the first driver 15 is hinged to the turntable 13.

[0012] For further information, please refer to Figure 3 and Figure 4 As shown, the rounding assembly 1 also includes two third jigs 14 that reciprocate between the rounding station and below the rounding station. When the third jig 14 is located at the rounding station, the first jig 11, the second jig 12 and the third jig 14 are alternately arranged in sequence.

[0013] It can be seen from the above description that the third fixture 14 can be used to further increase the number of stator winding modules used to form a stator component unit.

[0014] It is worth mentioning that please refer to Figure 3 and Figure 4 As shown, the circle assembly 1 includes a lifter 16, and the movable end of the lifter 16 is connected to the third fixture 14. Preferably, the lifter 16 is a cylinder.

[0015] It should be additionally explained that by increasing the number of circular components 1, the number of stator winding modules used in the stator can be increased.

[0016] Furthermore, the circle assembly 1 has a loading station, and the two second fixtures 12 reciprocate between the loading station and the circle assembly station.

[0017] It can be seen from the above description that the second fixture 12 is first moved to the loading station, which makes it easy for the robot to place the stator winding module on the second fixture 12.

[0018] It is worth mentioning that please refer to Figure 3 As shown, the circle assembly 1 includes a second reciprocating device 17 and a mounting plate 18. The movable end of the second reciprocating device 17 is connected to the mounting plate 18, and the second fixture 12 is arranged on the mounting plate 18. Preferably, the second reciprocating device 17 is a cylinder.

[0019] For further information, please refer to Figure 5 As shown, the above-mentioned stator circle assembly device also includes a shaping component 2, which includes a fixed jig 21 and a movable jig 22. The movable jig 22 is rotatably arranged on one side of the fixed jig 21 to make the movable jig 22 approach or move away from the fixed jig 21.

[0020] From the above description, it can be seen that according to the design requirements of the position of each phase of the stator, the two winding modules 4 of the stator winding module can be placed on the fixed jig 21 and the movable jig 22 respectively, and then the stator winding module is pre-shaped by the movable jig 22 to facilitate the robot to place the stator winding module on the corresponding jig on the circular component 1.

[0021] It is worth mentioning that please refer to Figure 6 As shown, the shaping assembly 2 includes a second driver 25 and a rotating shaft 26; the output end of the second driver 25 is transmission-connected to the rotating shaft 26, and the rotating shaft 26 is eccentrically connected to the movable fixture 22. Preferably, the second driver 25 is a cylinder, and a connecting block is provided at one end of the rotating shaft 26 away from the movable fixture 22, and the connecting block is hinged to the piston rod of the second driver 25.

[0022] For further information, please refer to Figure 5 As shown, the shaping assembly 2 also includes a first reciprocating device 23 and a first cross-line shaping block 24 . The first reciprocating device 23 has a movable end that moves toward the fixed fixture 21 , and the first cross-line shaping block 24 is connected to the movable end of the first reciprocating device 23 .

[0023] From the above description, it can be seen that the first cross-wire shaping block 24 is driven into position by the first reciprocating device 23, so that the movable fixture 22 can make the cross-wire 5 on the stator winding module lean against the first cross-wire shaping block 24 for bending during the process of shaping the stator winding module, thereby ensuring that the cross-wire 5 on each shaped stator winding module is bent in unison.

[0024] For further information, please refer to Figure 6As shown, the above-mentioned stator circle assembly device further includes a transition assembly 3, and the transition assembly 3 includes a mounting frame 31 and a second cross-wire shaping block 32 arranged on the mounting frame 31.

[0025] From the above description, it can be seen that when the robot moves the shaped stator winding module to the circular assembly 1, it will first place the jumper 5 on the stator winding module against the second jumper shaping block 32 for bending and shaping, so that the jumpers 5 on each shaped stator winding module are bent in the same way, ensuring that the jumpers 5 on each stator winding module can be neatly arranged on the stator after assembly.

[0026] A circle splicing method, comprising two winding modules 4, and using the same wire for winding on the two winding modules 4 to obtain a stator winding module; a plurality of the stator winding modules are combined to form a stator component unit, and one side of the winding module 4 of the stator winding module is the winding module 4 of another stator winding module; a plurality of the stator component units are combined to form a prototype of a stator; the stator is subjected to a shaping process to connect adjacent winding modules 4.

[0027] Furthermore, before the stator is subjected to the shaping process, the stator is subjected to a flattening process.

[0028] Furthermore, the leveling process is to vertically support the stator and apply pressure to the stator vertically downward.

[0029] In some embodiments, the stator is placed vertically on a positioning fixture, which has a positioning ring wrapped on the outer wall of the stator and a supporting component supported under the stator winding. The pressure device drives the pressure plate to press on the stator winding, and the pressure plate can squeeze the cross-wire 5. After the leveling is completed, each stator winding module is flush, ensuring the quality of subsequent stator shaping, and the cross-wire 5 on each stator winding module can be arranged more neatly on the stator after being pressed by the pressure plate. The pressure plate applies a pressure of 1.3t to 1.8t to the stator and maintains it for 3s to 5s.

[0030] Furthermore, the shaping process is a welding process, a riveting process, or a bonding process.

[0031] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
