[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention first returns the previously selected enameled wire to its position by cooperating with the first wire pressing assembly and the second wire pressing assembly, then the wire clamping assembly sends the enameled wire to the wire clamping assembly for clamping, and the first wire pressing assembly and the second wire pressing assembly cooperate to select the required enameled wire, thereby reducing the waste of wire ends and lowering costs;

[0020] (2) The wire to be selected is sent to the wire clamping assembly by the wire clamping assembly and clamped, and the unnecessary wire is pulled toward the wire barrel by the cooperation of the first wire pressing assembly and the second wire pressing assembly, so that the wire left at the wire clamping assembly is the required wire, which improves the efficiency of wire selection. In addition, due to the clamping of the wire clamping assembly, the enameled wire is not easy to bend or deform during the wire selection process;

[0021] (3) The third wire pressing assembly is used to clamp the wire extending from the second wire pressing assembly, thereby preventing the enameled wire from being bent and disordered when the wire outlet assembly is extended and retracted during the wire selection process, ensuring that the enameled wire is always neatly arranged during the wire selection process;

[0022] (4) During the wire feeding and clamping process, the piston rod of the wire passing cylinder extends to drive the rotating arm to rotate, thereby causing the wire blocking rod to retract and compress the elastic member, thereby leaving the wire passing groove on the wire passing clamp unobstructed and allowing the enameled wire to pass through. After the piston rod of the wire passing cylinder retracts, the wire blocking rod has no effect, and the wire blocking rod extends under the action of the elastic member, thereby passing through the wire passing groove to close it and prevent the enameled wire from escaping from the wire passing groove;

[0023] (5) The sliding shafts of the two mold arms are coaxial, so the two sets of slide blocks can be located at the same height, that is, the same linear guide rail can be used, which is simple in structure and reduces cost;

[0024] (6) Since the first sliding shaft and the second sliding shaft are splined, the first sliding shaft can be driven by the cylinder to move toward the side close to the second sliding shaft, thereby reducing the distance between the rear mold arm and the front mold arm, making it easier to push the coil down;

[0025] (7) The two mold arms can move in the same direction or in opposite directions, which can be used for winding coils of different sizes;

[0026] (8) The push block of the wire clamping assembly used for clamping the bridge wire is wedge-shaped, triangular or trapezoidal. This shape characteristic allows the push block to gradually reduce the gap between the clamping blocks under the drive of the cylinder, thereby producing a strong clamping effect on the bridge wire. This clamping method is stable and reliable and can effectively prevent the bridge wire from loosening or falling off under vibration or external force. By adjusting the position or angle of the push block, the clamping degree of the clamping block can be easily controlled. This adjustment method is simple and intuitive, and does not require complex tools or equipment. The operation of the wire clamping assembly is also relatively simple. The clamping block can be separated or clamped by simply pushing the push block, which improves work efficiency. The wire clamping assembly is suitable for bridge wires of different specifications and sizes. Since the design of the push block and the clamping block has a certain flexibility, it can adapt to cables of different diameters or cross-sections. The wedge-shaped, triangular or trapezoidal push block design makes the structure of the wire clamping assembly more compact and occupies less space.

[0027] (9) The cylinder pushes the wire push ring to slide along the linear guide rail to push the wound coil down, which has the advantages of high motion accuracy, stability and high efficiency;

[0028] (10) The spool can be locked or released through the latch positioning mechanism, which makes installation and removal quick and easy, thus improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0061] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the components or elements referred to must have a specific direction or be constructed and operated in a specific direction.

The wire clamping cylinder 1211 is installed on the wire clamping cylinder seat, and one end of the two wire clamping guide plates 1214 is respectively fixed on both sides of the wire clamping pressure plate 1213, and the other end is in the slide groove on both sides of the wire clamping base 1212, thereby playing a guiding role. The wire clamping cylinder 1211 drives the wire clamping pressure plate 1213 through the extension and retraction of the guide rod, thereby clamping the enameled wire 3 or releasing the enameled wire 3.

[0069] In one embodiment, the wire clamping assembly 11, the wire clamping assembly 12 and the wire cutting mechanism 5 are all installed on the YZ linear module 6. Since the wire selection mechanism 1 is installed as a whole on the linear guide rail in the X-axis direction, it can move along the front and back directions, up and down directions, and left and right directions. The wire cutting mechanism 5 includes a pneumatic scissors 51 and the pneumatic scissors 51 moves in the horizontal and vertical directions under the drive of the scissors horizontal moving mechanism 52 (realized by a cylinder) and the scissors lifting mechanism 53 (realized by the combination of a cylinder and a linear guide rail).

[0070] In one embodiment, the wire selection mechanism 1 further includes a third wire pressing assembly 15 and a wire outlet assembly 16, the third wire pressing assembly 15 includes a third wire pressing cylinder 151, a third wire pressing plate 152, and a pad 153, a third wire pressing channel is formed between the third wire pressing plate 152 and the pad 153, the third wire pressing cylinder 151 drives the third wire pressing plate 152 to compress or loosen the enameled wire 3 passing through the third wire pressing channel; the wire outlet assembly 16 includes a wire outlet seat 161 and a wire outlet pressure plate 162, a wire outlet channel for accommodating the enameled wire 3 is formed between the wire outlet seat 161 and the wire outlet pressure plate 162, the wire outlet seat 161 is driven by the wire outlet cylinder 163 to move horizontally on the linear guide rail, and in the initial state, the wire outlet assembly 16 is away from the third wire clamping device On one side of 15, when the first wire pressing assembly 13 and the second wire pressing assembly 14 cooperate to return the previously selected enameled wire 3 to its place, the wire outlet assembly 16 is pushed by the wire outlet cylinder 163 to the side close to the third wire clamping device 15, and when the wire clamping assembly 11 clamps the enameled wire 3, the wire outlet assembly 16 is pushed by the wire outlet cylinder 163 to the side away from the third wire clamping device 15, and the wire outlet assembly 16 can prevent the enameled wire 3 from falling out and make the enameled wire 3 extend along a predetermined trajectory. In addition, when the wire outlet assembly 16 moves left and right, the enameled wire 3 is easily bent and disordered, and the enameled wire 3 extending from the second wire pressing assembly 14 is clamped by the third wire clamping device 15, thereby ensuring that the enameled wire 3 is always neatly arranged during the wire selection process.

[0071] In one embodiment, the winding machine mold 21 includes a rear mold 211, a front mold 212, a first sliding shaft 213 and a second sliding shaft 214. The rear mold 211 and the front mold 212 are slidably installed on the rotating seat 217. The first sliding shaft 213 and the second sliding shaft 214 are coaxially arranged, so there is no height difference. Therefore, the rear mold 211 and the front mold 212 can share the same linear guide rail, which simplifies the structure and reduces the cost. In addition, only one motor is needed to drive the two sliding shafts to rotate at the same time. Specifically, the motor is connected to one of the sliding shafts through a transmission mechanism (which can be a gear transmission, a belt transmission, a chain transmission, etc.); in addition, the first sliding shaft 213 and the second sliding shaft 214 are both screws, and the screw is driven by The two screws are connected to the rear mold 211 and the front mold 212 through nuts. As needed, when the two screws rotate, the two nuts thereon can move toward or away from each other, so that the rear mold 211 can slide toward or away from each other along the first sliding shaft 213 and the front mold 212 can slide along the second sliding shaft 214. After the coil model is determined, the distance between the rear mold 211 and the front mold 212 is fixed. Only after the coil model is changed, the two sliding shafts are driven by a motor to adjust the distance between the rear mold 211 and the front mold 212. The first sliding shaft 213 and the second sliding shaft 214 are coaxial through spline matching, and rectangular splines, involute splines and triangular splines can be used for connection. Figure 16 The structure shown is that the first end of the first sliding shaft 213 has two symmetrical flattened planes, and one end of the second sliding shaft 214 has an insertion hole that matches the shape of the first end of the first sliding shaft 213, and the first end of the first sliding shaft 213 is inserted into the insertion hole of the second sliding shaft 214.

[0072] In one embodiment, the rear mold 211 includes a rear mold arm 2111, a rear mold clamping assembly I 2112, a rear mold clamping assembly II 2114 and a hook wire seat 2115. The rear mold arm 2111 is installed on the first sliding seat 2113, and the rear mold clamping assembly I 2112 is installed on the top of the rear mold arm 2111. The rear mold clamping assembly II 2114 and the hook wire seat 2115 are both installed on the first sliding seat 2113. The first sliding seat 2113 is connected to the slider in the linear guide pair on the rotating seat 217, so that it can slide along the linear guide. The rear mold clamping assembly I 2112 includes a clamping cylinder I 21221, a clamping rod 21122 and a clamping head. The clamping head includes a clamping base 21123, a first clamping block 2112 4. The second wire clamping block 21125 and the push block 21126 are provided with a wire clamping groove on the top of the wire clamping base 21123. The first wire clamping block 21124 and the second wire clamping block 21125 are installed in the cavity of the wire clamping base 21123. The push block 21126 is slidably installed between the first wire clamping block 21124 and the second wire clamping block 21125 through the protrusions on both sides. The opposite surfaces of the left and right clamping blocks for installing one end of the push block 21126 are inclined surfaces, so the left and right clamping blocks can form a wedge-shaped, triangular or trapezoidal space at this end, and this space is narrow at one end close to the wire clamping groove and wide at the other end, and the push block 21126 matches the shape of this space, which is wedge-shaped, triangular or trapezoidal; the wire clamping cylinder 1 passes through The telescopic pulling of the wire clamping rod 21122 pulls the pushing block 21126 to move the first wire clamping block 21124 and the second wire clamping block 21125 closer to or apart, thereby being used to clamp or loosen the bridge wire; the structure of the rear mold wire clamping assembly II 2114 is the same as that of the second clamping head assembly 121, and can be used to clamp the enameled wire 3 selected from the wire selection mechanism 1 so that the mold can be wound; the front mold 212 is connected to the slider in the linear guide pair on the rotating seat 217 through the second sliding seat, so that it can slide along the linear guide, the front mold 212 includes a front mold arm 2121 and a wire pushing ring 2122, and the wire pushing ring 2122 is slidably installed on the front mold arm 2121 through the wire pushing plate 2123, and the wire pushing plate 2123 is connected to the wire pushing lifting cylinder 2124 The wire pushing ring 2122 is connected and driven by the wire pushing lifting cylinder 2124 to slide up and down along the front mold arm 2121. Since the coil is wound tightly on the rear mold arm 2111 and the front mold arm 2121, it is difficult to push it down through the wire pushing ring 2122. However, at this time, if the rear mold 211 and the front mold 212 move toward each other to reduce the distance between them so that the coil can be pushed down easily, the movement of the front mold 212 will damage the wire hanging cup. The first sliding shaft 213 can move within the second sliding shaft 214 driven by the moving seat cylinder 215. Therefore, the moving seat 216 is installed on the first sliding shaft 213 through a bearing and the moving seat 216 is driven by the moving seat cylinder 215. Since the first sliding shaft 213 and the second sliding shaft 214 are connected as shown in FIG. Figure 15-16The keys are matched in the manner shown, and in the initial state, the first end of the first sliding shaft 213 is at a certain distance from the side wall of the insertion hole in the second sliding shaft 214. Therefore, at this time, the piston rod of the movable seat cylinder 215 is retracted (the piston rod is in an extended state when the coil is wound), so that the first sliding shaft 213 moves in the insertion hole of the second sliding shaft 214 toward the side close to the second sliding shaft 214, thereby causing the rear mold arm 2111 to move toward the direction close to the front mold arm 2121, and the distance between the front mold arm 2121 and the rear mold arm 2111 is reduced, which facilitates the pushing down of the coil.

[0073] In one embodiment, the spool assembly 22 includes a spool 221 and a latch positioning assembly 222. The spool 221 is locked or released by the latch positioning assembly 222. The latch positioning mechanism includes a positioning latch and a positioning latch cylinder. The two positioning latches are extended by the positioning latch cylinder to press the spool 221. The two positioning latches are retracted by the positioning latch cylinder to release the spool 221, so that the spool 221 can be removed. The spool 221 is lifted and lowered by the spool lifting drive mechanism 223 and rotated by the spool rotation drive mechanism 224 (which can be a motor). The spool lifting drive mechanism 223 includes a spool lifting cylinder, a lifting screw pair, and a gear set. The spool lifting cylinder drives the lifting seat installed on the lifting screw pair to lift and lower through the gear set, and the spool 221 is installed on the lifting seat.

[0074] In one embodiment, the winding mechanism 2 also includes a spool transfer platform 23, which includes a rotating platform 231 and a divider 232. The divider 232 is installed at the bottom of the rotating platform 231 and is driven by a motor. A placement position for the spool 221 is provided on the rotating platform 231. The spool 221 after the coil is placed slides on the wire selection base 4 to the placement position of the rotating platform 231, and the spool 221 is transferred to the placement position.

[0075] Working principle:

[0076] N enameled wires 3 are output from N wire barrels 72, pass through their respective wire wheel assemblies 73 and are collected by the wire passing vertical plate assembly 74 into the corresponding wire passing groove in the enameled wire fixing assembly 75, and are transported to the wire selection mechanism 1 for wire selection. In the initial state of wire selection, the wire output assembly 16 is on the side away from the third wire pressing assembly 14. After the first wire pressing assembly 13 and the second wire pressing assembly 14 cooperate to return the previously selected enameled wire 3 to its place, the wire output assembly 16 moves to the side close to the third wire pressing assembly 14 under the push of the wire output cylinder 163, the wire clamping assembly 11 and the wire clamping and pulling assembly 12 descend, and the wire clamping and pulling assembly 1 2 clamps the enameled wire 3 and moves it to the side close to the wire clamping assembly 11. The wire clamping assembly 11 rises and clamps the enameled wire 3 through the first clamping head assembly 112. Then, the wire outlet assembly 16 moves to the side away from the third wire pressing assembly 14. The wire clamping and pulling assembly 12 moves up and to the right. The combing seat moves to one end close to the first clamping head assembly 112 under the drive of the combing cylinder to comb the enameled wire 3. The first wire pressing assembly 13 and the second wire pressing assembly 14 cooperate to pull the unnecessary enameled wire 3 to the right. The required enameled wire 3 remains at the wire clamping assembly 11. After the wire selection is completed, the selected enameled wire 3 is pulled to the rear mold clamp The wire assembly II is clamped, the rotating seat 217 rotates, and the coil winding begins. After the coil winding is completed, the wire cutting mechanism 5 slides to one side of the winding mechanism 2 on the linear guide rail on the wire selection base 4 through the YZ linear module 6, and then the enameled wire 3 is cut by the cooperation of the scissor horizontal moving mechanism 52 and the scissor lifting mechanism 53. At this time, the spool 221 is driven by the spool lifting drive mechanism 223 to rise to a position close to the winding machine mold 21, and then driven by the spool rotation drive mechanism 224 to rotate, so that the spool 221 is facing the wound coil, and the iron core is placed on the spool 221. , then the movable seat cylinder 215 in the winding machine mold 21 retracts, causing the rear mold 211 to move toward the front mold 212, and the distance between the rear mold 211 and the front mold 212 is reduced. The wire pushing ring 2122 slides downward along the front mold arm 2121 under the drive of the wire pushing lifting cylinder 2124, so that the wound coil is pushed to the spool cup 221 and placed on the iron core, and then moves along the linear guide rail to the spool cup transfer platform 23. The positioning pin is retracted under the drive of the positioning pin cylinder to release the spool cup 221, so that it can be removed and transferred to the spool cup transfer platform 23 for the next process.
