Description

Technical Field

[0001] The present invention relates to the technical field of stator coil production, and particularly to a wire arranging mechanism for arranging the wire ends of a stator coil. Background Art

[0002] The stator winding is assembled by multiple coils. After the winding of the coils is completed, the wire ends thereon are arranged upward and the directions of each wire end are different. Therefore, after the assembly of the stator winding is completed, in order to better connect the wire ends, it is necessary to bend and arrange the wire ends. In the existing devices, most of them are semi-automatic, that is, some operations need to be carried out manually. For example, Chinese Patent CN202121665524.4 discloses a lead wire end bending device for an automotive motor stator coil, which includes a base, a slide rail, a slider, a bending guide wheel and a first cylinder; a slide rail is provided on one side of the top of the base, and a first cylinder is provided on the other side. The slider is slidably connected to the top of the slide rail, and one side of the slider is connected to the output end of the first cylinder; a bending guide wheel is rotatably connected to the top of the slider; a backing plate is provided behind the slide rail. This device can bend the lead wire ends of the coil twice, but its degree of automation is not high, and workers need to hold the coil body and place the lead wire ends into the device for bending, wasting human resources.

[0018] The following further details the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein does not limit the protection scope of the present invention.

[0019] Such as Figure 1As shown, it is a schematic structural diagram of a wire arranging mechanism for arranging the lead wires of a stator coil provided by the present invention. The wire arranging mechanism for arranging the lead wires of a stator coil includes a wire clamping assembly 10, a positioning and clamping assembly 20 disposed on one side of the wire clamping assembly 10, and a rotating assembly 30 disposed on one side of the positioning and clamping assembly 20. It can be imagined that the wire arranging mechanism for arranging the lead wires of a stator coil also includes some other functional modules, such as a screw module, a power supply module, a control module, etc., which are well-known technologies to those skilled in the art and will not be elaborated here one by one.

[0020] Please refer to Figures 2 to 5 . It should be noted that a stator winding 40 is clamped on the positioning and clamping assembly 20. The stator winding 40 includes at least one coil 41 and a lead wire 42 disposed on the coil 41. After multiple pre-processes such as winding and assembling of the stator winding 40 by a plurality of coils 41 are completed, several lead wires 42 will be arranged at intervals and are generally in a vertical state but not completely neat. Therefore, the wire arranging mechanism for arranging the lead wires of a stator coil needs to perform bending and wire arranging operations on the lead wires 42 to facilitate the insertion of the subsequent bus bar. A plurality of slots 43 are provided on the circumferential outer wall of the stator winding 40, and the slots 43 can be used for positioning by the positioning and clamping assembly 20. The specific positioning method will be described below.

[0021] The wire clamping assembly 10 includes at least one support column 11, a support plate 12 penetrating through the support column 11, a slide table cylinder 13 disposed on the support plate 12, a wire clamping cylinder 14 disposed at the output end of the slide table cylinder 13, and a fixture 15 disposed at the output end of the wire clamping cylinder 14.

[0022] The support plate 12 penetrates through the support column 11 and is fixed to the support column 11 by screws. The height position of the support plate 12 on the support column 11 can be adjusted by a knob screw, so as to cooperate with the positioning and clamping assembly 20 to adjust the wire clamping position.

[0023] The output direction of the slide table cylinder 13 faces the positioning and clamping assembly 20, and the slide table cylinder 13 can drive the wire clamping cylinder 14 to reciprocate in this direction. The wire clamping cylinder 14 can control the opening and closing actions of the fixture 15, so that the fixture 15 can clamp the lead wire 42. The slide table cylinder 13 pulls back, thus arranging and bending the lead wire 42. After the rotating assembly 30 controls the positioning and clamping assembly 20 to rotate by an angle, the above operations are repeated to complete the bending and wire arranging operations on the stator winding 40.

[0024] The positioning and clamping assembly 20 includes a central column 21, a lifting cylinder 22 disposed on one side of the central column 21, a lifting plate 23 disposed at the output end of the lifting cylinder 22, a lifting column 24 inserted into the central column 21, a retaining rod 25 inserted on the lifting column 24, a spring 26 disposed at one end of the lifting column 24, two adjusting rods 27 disposed at the other end of the lifting column 24, and a positioning seat 28 disposed around the lifting column 24.

[0025] The central column 21 is hollow along its length direction, so that the lifting column 24 and the spring 26 are slidably inserted into the central column 21. Two first sliding grooves 211 for inserting the retaining rod 25 are oppositely formed on the circumferential outer side wall of the central column 21. The retaining rod 25 is fixedly inserted through the lifting column 24 and its two ends respectively pass through the first sliding grooves 211. The length direction of the retaining rod 25 is perpendicular to the length direction of the lifting column 24. A fixed disk 212 is disposed at one end of the central column 21 close to the spring 26, and a limiting disk 213 is disposed in the middle section of the central column 21. The fixed disk 212 is fixedly connected to the rotating assembly 31 by screws. The limiting disk 213 is mainly used to limit the lifting plate 23, and the specific limiting method will be described below.

[0026] One end of the lifting plate 23 has an arc-shaped opening matching the central column 21. The inner side wall of the arc-shaped opening is in contact with the circumferential outer side wall of the central column 21 and is located between the fixed disk 212 and the limiting disk 213. In this way, the lifting plate 23 is limited by the limiting disk 213, and at the same time, the retaining rod 25 is located in the moving direction of the lifting plate 23. The output direction of the lifting cylinder 22 is parallel to the length direction of the central column 21, and the lifting cylinder 22 can drive the lifting plate 23 to make a reciprocating motion between the fixed disk 212 and the limiting disk 213. When the lifting plate 23 moves towards the fixed disk 212, it will push the retaining rod 25 to one end of the first sliding groove 211 facing the fixed disk 212, and the lifting column 24 will move towards the spring 26 under the drive of the retaining rod 25 and compress the spring 26. In this way, the lifting column 24 can have a potential energy towards the direction away from the spring 26 when the lifting plate 23 moves towards the limiting disk 213, so that the end of the lifting column 24 away from the spring 26 can cooperate with the adjusting rod 27 and the positioning seat 28 to achieve the function of fixedly clamping the stator winding 40, and the specific clamping method will be described below.

[0027] One end of the central column 21 away from the spring 26 is provided with a strip-shaped groove 214. A pin shaft 215 is rotatably arranged at each of the two ends of the strip-shaped groove 214. The pin shaft 215 is used to penetrate the middle section of the adjusting rod 27. On both sides of one end of the adjusting rod 27, a sliding column 271 is respectively arranged. Two second sliding grooves 241 are opened at one end of the lifting column 24 away from the spring 26. The two sliding columns 271 are respectively clamped into the two second sliding grooves 241 and the sliding column 271 can slide in the second sliding groove 241. Thus, when the lifting column 24 descends or ascends, the sliding column 271 will move in the second sliding groove 241, so that the adjusting rod 27 rotates around the pin shaft 215. Furthermore, one end of the adjusting rod 27 away from the sliding column 271 will swing up and down. One end of the adjusting rod 27 away from the sliding column 271 is provided with a clamping step 272, which matches the inner edge of the stator winding 40. The clamping step 272 can clamp the stator winding 40 while the elastic potential energy of the spring 26 is released, so as to play a role in fixedly clamping the stator winding 40.

[0028] A positioning block 281 protruding inward is arranged on the positioning seat 28. The positioning block 281 is clamped into the slotted groove 43, so as to prevent relative rotation when the rotating assembly 30 rotates, thus completing the positioning effect.

[0029] The rotating assembly 30 includes a rotating motor 31, a rotating seat 32 arranged at the output end of the rotating motor 31, an induction sheet 33 arranged on the circumferential outer side wall of the rotating seat 32, and an inductor 34 arranged on one side of the rotating seat 32.

[0030] The rotating motor 31 can drive the rotating seat 32 to rotate. The rotating seat 32 is fixedly connected to the fixed disc 212 by screws, so as to drive the central column 21 to rotate. The initial position of the induction sheet 33 is located in the inductor 34. When the rotating seat 32 rotates one full circle, the induction sheet 33 returns to the initial position again, so that the inductor 34 knows that the bending and wire arranging operation of one stator winding 40 has been completed.

[0031] The rotating assembly 30 further includes a rolling bearing 35 arranged on one side of the positioning seat 28. The circumferential outer side wall of the rolling bearing 35 is connected to the bracket part of the mechanism, and the circumferential inner side wall of the rolling bearing 35 is connected to the positioning seat 28, so as to be able to perform a rotating operation while supporting the positioning seat 28.

[0032] Compared with the prior art, the lead wire arranging mechanism for arranging the lead wires of the stator coil positions the stator winding 40 in the positioning seat 28 through the clamping and positioning assembly 20, and clamps the lead wire 42 by the wire clamping assembly 10 to perform the bending and wire arranging operation. After completing the bending and wire arranging operation of one lead wire 42, the stator winding 40 is rotated by the rotating assembly 30 to perform the bending and wire arranging operation of the next lead wire 42. The lead wire arranging mechanism for arranging the lead wires of the stator coil does not require manual operation throughout the process, has a high degree of automation, and saves human resources.

[0033] The above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
