[0023] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] like Figure 1 As shown, a motor winding machine 1 is used for the winding process of producing a stator 2 in a motor. The stator 2 includes stator teeth 21 and stator slots 22. The stator teeth 21 are evenly arranged, and the gap between adjacent stator teeth 21 is the stator slot 22. The motor winding machine 1 winds copper wire onto the stator teeth 21.

[0025] like Figure 1The motor winding machine 1 shown includes an operating table 11, a wire feeding assembly 12, a wire delivery assembly 13, and a winding assembly 14. The wire feeding assembly 12, the wire delivery assembly 13, and the winding assembly 14 are sequentially installed on the operating table 11. The wire feeding assembly 12 and the winding assembly 14 are installed in the front and rear directions of the wire delivery assembly 13, respectively. The copper wire coil is placed on the wire feeding assembly 12. The copper wire is released from the wire feeding assembly 12, passes through the wire delivery assembly 13, and enters the winding assembly 14. The winding assembly 14 winds the copper wire onto the stator 2.

[0026] like Figure 2 As shown, the wire feeding assembly 13 includes a hollow motor 131, a coupling 132, a positioning element 133, and a wire guide 134. The input end of the hollow motor 131 is connected to the coupling 132, and the output end is connected to the positioning element 133. The wire guide 134 is fixed on the positioning element 133. The copper wire enters the hollow motor 131 from the coupling 132, passes through the output end of the hollow motor 131, passes through the positioning element 133, enters the wire guide 134, and then passes through the wire guide 134 to enter the winding assembly 14.

[0027] like Figure 3 As shown, the positioning component 133 includes a first positioning disk 1331, a second positioning disk 1332, and a positioning shaft 1333. The first positioning disk 1331 is installed at the output end of the hollow motor 131. The second positioning disk 1332 is coaxial with the first positioning disk 1331. Multiple positioning shafts 1333 are evenly arranged between the first positioning disk 1331 and the second positioning disk 1332. The positioning shafts 1333 are used to limit the movement range of the copper wire.

[0028] like Figure 3 As shown, the guide wire 134 is a hollow needle shape. The guide wire 134 is fixed on the edge of the second positioning disk 1332. The needle end of the guide wire 134 extends into the stator slot 22. The copper wire passes through the needle end of the guide wire 134 and enters the winding assembly 14 for winding. The guide wire 134 rotates around the stator tooth 21 to wind the copper wire onto the stator tooth 21. After winding, it exits the stator slot 22.

[0029] like Figure 2 As shown, the wire feeding assembly 13 also includes a horizontal motion unit 135 and a mounting frame 136. The horizontal motion unit 135 is fixed on the operating table 11, the mounting frame 136 is mounted on the horizontal motion unit 135, and the hollow motor 131 is fixedly mounted on the mounting frame 136. The horizontal motion unit 135 drives the hollow motor 131 to reciprocate horizontally.

[0030] like Figure 2 As shown, the wire feeding assembly 13 also includes a first proximity switch 137 and a second proximity switch 138. The first proximity switch 137 is disposed on the horizontal motion unit 135 and is used to detect whether the hollow motor 131 has returned to its initial position. The second proximity switch 138 is connected to the mounting bracket 136 and is used to detect the number of rotations of the positioning member 133, i.e., the number of turns of the copper wire.

[0031] Accordingly, such as Figure 3 As shown, the positioning component 133 also includes a bending portion 1334, which is fixed on the first positioning disk 1331. The bending portion 1334 extends out of the first positioning disk 1331 and bends. The bending portion 1334 is preferably arranged horizontally or vertically. When the bending portion 1334 is in the initial position, it is close to the second proximity switch 138. After making one turn, it returns to the original position and triggers the second proximity switch 138. This is recorded as making one turn.

[0032] like Figure 2 As shown, the horizontal motion unit 135 includes a base 1351 and a track 1352. The base 1351 is fixed on the operating table 11, and the track 1352 is fixed on the base 1351.

[0033] like Figure 2 As shown, the horizontal motion unit 135 further includes a first driving member 1353, a driving rod 1354, and a sliding seat 1355. The first driving member 1353 is mounted on the base 1351, and its output end is connected to the driving rod 1353. The driving rod 1354 is connected to the sliding seat 1355. The first driving member 1353 drives the driving rod 1354, and the driving rod 1354 causes the sliding seat 1355 to move along the track 1352.

[0034] Specifically, the mounting bracket 136 is fixed on the sliding seat 1355, the hollow motor 131 is mounted on the mounting bracket 136, and the hollow motor 131 moves synchronously with the sliding seat 1355.

[0035] Specifically, the first proximity switch 137 is mounted on the base 1351. The detection port of the first proximity switch 137 is raised and aligned with the initial position of the sliding seat 1355 to prevent the track 1352 from affecting the detection of the first proximity switch 137. When the sliding seat 1355 returns to the initial position after horizontal reciprocating motion, the first proximity switch 137 is triggered.

[0036] Specifically, the drive rod 1354 can be a threaded rod, and the first drive member 1353 can be a servo motor; in another embodiment, the drive rod 1354 can also be a push rod, which together with the first drive member 1353 forms a push rod cylinder or a push rod motor.

[0037] like Figure 2 As shown, the horizontal motion unit 135 also includes a limiting member 1356, which is mounted on the base 1351. The drive rod 1354 passes through the limiting member 1356 and is connected to the sliding seat 1355. The limiting member 1356 is used to limit the position of the drive rod 1354.

[0038] like Figure 2 As shown, the winding assembly 14 includes a bracket 141, a second drive member 142, a bearing 143, and a pressure plate 144. The bracket 141 is fixed on the operating table 11. The second drive member 142 is mounted on the bracket 141. The output end of the second drive member 142 is fitted with the bearing 143. The pressure plate 144 is fitted on the outside of the bearing 143. The pressure plate 144 is used to press the stator 2 to prevent the stator 2 from shifting during the winding process, which could lead to winding errors.

[0039] Specifically, the second driving component 142 is a push rod cylinder, the bearing 143 and the pressure plate 144 are installed at the end of the push rod, the stator 2 is placed below the second driving component 142, and the second driving component 142 drives the pressure plate 144 to press the stator 2, so as to facilitate the winding of the stator 2.

[0040] like Figure 3 As shown, the winding assembly 14 also includes a third drive member 145 and a flange 146. The third drive member 145 is vertically installed in the operating table 11 with its output end facing upwards. The flange 146 is fitted onto the output end of the third drive member 145.

[0041] Specifically, the stator 2 is placed on the flange 146, and the second driving member 142 drives the pressure plate 144 to press the stator 2 to prevent the stator 2 from shifting during winding. After the current stator tooth 21 is wound, the third driving member 145 drives the flange 146 to rotate at a certain angle, the rotation angle = 360° / number of stator slots. The pressure plate 144, the stator 2 and the flange 146 rotate synchronously to continue winding the next stator tooth 21.

[0042] like Figure 4As shown, the copper wire routing path on the motor winding machine 1 is as follows: the copper wire coil is placed on the wire feeding assembly 12, and the end of the copper wire extends from the wire feeding assembly 12 into the wire feeding assembly 13. The copper wire enters the interior of the hollow motor 131 from the coupling 132, exits from the output end of the hollow motor 131, passes through the positioning member 133 and enters the wire guide member 134. The copper wire exits from the needle end of the wire guide member 134 and is wound on the stator teeth 21 of the stator 2.

[0043] The working process of the motor winding machine 1 is as follows: In the initial state, the sliding seat 1355 is in the initial position, the first proximity switch 137 is aligned with the sliding seat 1355, and the second proximity switch 138 is aligned with the bending part 1334. The second driving member 142 is activated, which drives the pressure plate 144 to move downward, and the pressure plate 144 presses the stator 2 against the flange 146. The first driving member 1353 is activated, which drives the driving rod 1354, and the driving rod 1354 drives the sliding seat 1355 away from the initial position. The sliding seat 1355 moves along the track 1352 towards the stator 2, thereby moving the hollow motor 131 towards the stator 2 until the tip of the guide wire 134 enters the stator slot 22. After the copper wire is wound onto the first stator tooth 21, the number of turns is set, and the hollow motor 131 is started. The hollow motor 131 drives the positioning member 133 to rotate, which in turn drives the wire guide member 134 to rotate around the stator tooth 21. The bending part 1334 triggers the second proximity switch 138 multiple times, and the number of turns is recorded. The second driving member 142 synchronously drives the hollow motor 131 to move away from the stator 2 at a constant speed, so that the copper wire is evenly wound on the stator tooth 21 until the sliding seat 1355 returns to the initial position and triggers the first proximity switch 137. At this time, the wire guide member 134 exits the stator slot 22, and the wire unwinding action is completed synchronously.

[0044] After the current stator tooth 21 is wound, the third drive member 145 drives the flange 146 to rotate, and the stator 2 and the pressure plate 144 rotate synchronously, rotating the next stator tooth 21 to be processed to the processing point. The first drive member 1353 then drives the hollow motor 131 to approach the stator 2, and the guide wire member 134 extends into the stator slot 22, repeating the above winding action.

[0045] This utility model discloses a motor winding machine with a simple structure, suitable for stators of different specifications; it has high winding precision and accurate wire arrangement, and can complete the wire arrangement action simultaneously during the winding process, making the winding action smooth and improving the quality and production efficiency of the wound coil.

[0046] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
