Description

Technical Field

[0001] The invention relates to a winding system for a stator coil. Background Art

[0002] In the prior art, the coils wound by the automated winding machine will have a certain length of lead wire left. After the stator wire embedding process is completed, the lead wires will be trimmed, connected and welded according to the design requirements, and finally wrapped with an insulating protective cover to finalize the shape. In actual applications, because each turn of the coil has several copper wires wound together, the lead wires of the coils are very messy. Each time the wires are wound and the coils are embedded in the stator core, a manual process needs to be arranged to sort out the lead wires, and the degree of automation is low. Each time a coil is wound, the lead wires need to be wrapped with tape or rolled up to facilitate the automation of the subsequent wire embedding process. It can be seen that the manual method of sorting out the coil leads in the prior art is very inefficient and has high labor costs. Summary of the invention

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 3 As shown, a winding system for a stator coil includes an equipment frame 200, a winding mechanism arranged on the equipment frame 200, the winding mechanism includes a winding die 21, a flying fork 22 for winding a wire 20 onto the winding die 21, and a wire hooking arm 23 for hooking the wire 20 and cutting the wire 20 after a coil is wound. The wire 20 hooked by the wire hooking arm 23 is a lead wire 20'. The winding system also includes a lead wire arranging mechanism arranged on the equipment frame 200. When the coil is wound for the first time, a winding wire is first wound. The coiled material (there are multiple wires 20 in the coiled material, and the multiple wires form a strand), one end of the stranded wire 20 (the end of the lead wire 20') is passed from the top of the winding mechanism to the flying fork 22, and the head is hooked and fixed by the hooking arm 23, and then the flying fork 22 rotates. Since the end of the lead wire 20' has been fixed by the hooking arm 23, when the flying fork 22 rotates, the coiled material will be continuously wound onto the winding mold 21 to form a coil. After winding, the lead wire arranging mechanism arranges the lead wire 20' hooked by the hooking arm 23.

[0023] In this example, the lead wire arranging mechanism is used to arrange the lead wire 20' hooked by the wire hook arm 23. The lead wire arranging mechanism includes a winding mechanism for winding the lead wire 20' hooked by the wire hook arm 23 after a coil is wound. The winding mechanism can move in the up and down directions, and when the winding mechanism moves from bottom to top, it can dock with the lead wire 20' and can wind up the lead wire 20'. The lead wire arranging mechanism also includes a first driving mechanism for driving the winding mechanism to move up and down.

[0024] Specifically, the winding mechanism includes a support frame slidably arranged in the up-down direction, a winding fork rotatably arranged on the support frame, a second driving mechanism driving the winding fork to rotate, and a wire removing mechanism for removing the lead wire 20' wound on the winding fork from the winding fork.

[0025] The support frame includes a frame 11, a support arm 12 rotatably arranged relative to the frame 11, and the winding fork is rotatably arranged on the support arm 12. The winding mechanism also includes a third driving mechanism for driving the support arm 12 to rotate, and the third driving mechanism is arranged on the frame 11; wherein, the frame 11 is arranged to slide in the up and down directions, and the first driving mechanism drives the frame 11 to move up and down.

[0026] The third driving mechanism includes a first driver q1 (a motor) fixedly mounted on the frame 11, a support shaft rotatably mounted on the frame 11, a first synchronous belt d1 drivingly connected between the rotational force output shaft of the first driver q1 and the support shaft, and a support arm 12 fixedly connected to the support shaft. The support shaft extends in the up-down direction, the support arm 12 is fixedly connected to the upper end of the support shaft, and the first synchronous belt d1 is drivingly connected between the lower end of the support shaft and the rotational force output shaft of the first driver q1.

[0027] Furthermore, the equipment frame 200 is connected to a support plate 100, and the first driving mechanism includes a driving cylinder 10 fixedly arranged on the support plate 100, and two driving cylinders 10 are provided, and the two driving cylinders 10 drive the frame 11 to move up and down, and the driving cylinders 10 are located in the middle of the frame 11 in the vertical direction. One end of the support arm 12 is fixedly connected to the support shaft, and the winding fork is located on the other end of the support arm 12. The second driving mechanism includes a second driver q2 (a motor), a transmission assembly that is transmission-connected between the rotation force output shaft of the second driver q2 and the winding fork, and the second driver q2 is arranged on the frame 11.

[0028] The transmission assembly includes a transmission sleeve d23, a second synchronous belt d2, and a third synchronous belt d3. The transmission sleeve d23 is rotatably mounted on the support shaft. The second synchronous belt d2 is transmission-connected between the rotational force output shaft of the second driver q2 and the transmission sleeve d23. The third synchronous belt d3 is transmission-connected between the transmission sleeve d23 and the winding fork. Through the setting of the two synchronous belts, when the third driving mechanism drives the support arm 12 to rotate and changes the position of the winding fork, the transmission relationship between the second driver q2 and the winding fork will not be changed, that is, after the position of the winding fork changes, the second driver q2 can still provide power for the winding fork to wind the lead 20'.

[0029] Furthermore, the wire winding fork includes a column body a30 and four fork bodies a31 fixed on the column body a30, the wire stripping mechanism includes a wire stripping cylinder a1 and a wire stripping block a2 slidably arranged relative to the wire winding fork, the wire stripping cylinder a1 is arranged on the support arm 12 and is located below the wire winding fork, and the output shaft of the wire stripping cylinder a1 passes through the center of the column body a30 and is fixedly connected to the wire stripping block a2; after the lead wire 20' is wound, the output shaft of the wire stripping cylinder a1 is pushed upward, thereby driving the wire stripping block a2 to move upward and causing the lead wire 20' wound on the fork body a31 to be stripped off from the fork body a31.

[0030] The specific conditions of the winding mechanism of the present invention when working are as follows: first, the wire hooking arm 23 hooks the lead wire 20', and after a coil is wound, the wire hooking arm 23 moves to the left or right and aligns the lead wire 20' with the winding fork, and then the entire winding mechanism of the first driving mechanism moves upward, that is, the winding fork moves upward, and the lead wire 20' is stuck between the fork bodies a31 of the winding fork, and then the second driver q2 starts to act and the winding fork starts to rotate; after the winding fork winds the lead wire 20' for a section, the first driver q1 in the third driving mechanism starts to start, so that the support shaft drives the support arm 12 to rotate, so that the winding fork on the support arm 12 moves closer to the winding mold 21, so that the winding fork can complete the winding of the entire section of the lead wire 20'.

[0031] To summarize, the winding system of the stator coil of the present invention, in addition to the winding mechanism, also includes a lead wire sorting mechanism. After a coil is completed with automatic winding, the lead wire hooked by the wire hooking arm can be automatically wrapped by coordinating the wire hooking arm and the lead wire sorting mechanism in the winding mechanism, thereby eliminating the subsequent complex steps of manual wrapping, thereby reducing labor cost expenditure, improving lead wire sorting efficiency, and improving product quality.

[0032] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
