Description

Technical Field

[0001] The utility model relates to a processing device for a stator coil, and more specifically, to a parametric adjustment mechanism for a wire winding device of a winding and embedding integrated machine. Background Art

[0002] The coil inside a transformer is an important component of the transformer. The quality of the coil determines the quality of the transformer product and its safety during operation. During the production of the coil, it needs to be installed on a wire winding mold and wound. Currently, most wire winding molds are fixed and cannot be adjusted. When producing coils of different specifications, the wire winding mold needs to be replaced. In an enterprise, dozens or even hundreds of wire winding molds need to be equipped to adapt to coils of different specifications. Moreover, the wire winding mold is heavy, and the replacement process is time-consuming and laborious. Also, strict classification management of the wire winding mold is required for subsequent use, and at the same time, the procurement cost of the wire winding mold is very high.

[0003] Chinese Patent with Application No. 201620502065.0 discloses a motor wire winding mold frame, which includes an upper template, a lower template, a first module group, and a second module group. The upper template is composed of a left upper template and a right upper template inserted together, the lower template is composed of a left lower template and a right lower template inserted together, the first module group is fixed on the left upper template and the left lower template, and the second module group is fixed on the right upper template and the right lower template. In this utility model, by splitting the upper template and the lower template into two mutually inserted sub-templates respectively, and opening pin holes on the insertion rod and the slot, during use, the distance between the first module group and the second module group can be adjusted by adjusting the insertion depth of the insertion rod and the pin connection position of the insertion rod and the slot, so as to meet the winding requirements of coils of different sizes. The motor wire winding mold frame provided by this utility model has the advantages of simple structure, convenient use, easy manufacturing and installation, and can be used for winding coils of different sizes.

[0004] Another example is that Chinese Patent with Application No. 201620677480.X discloses an adjustable wire winding template, which includes: a rotating shaft; two support plates located at both ends of the rotating shaft respectively, arranged in parallel and clamped on the rotating shaft; two nylon molds symmetrically arranged on both sides of the support plates, and each nylon mold is located between the two parallel support plates respectively, and the two ends of the nylon mold are connected to the support plates through threaded fasteners; the support plate includes a fixed plate and two moving plates, and the two moving plates are slidably connected to both ends of the fixed plate. The adjustable wire winding template provided by this utility model changes the length of the support plate through the moving plates at both ends of the support plate, and then changes the relative distance between the nylon molds on both sides of the support plate to realize the use of different cable lengths.

[0005] Although the above two patents can both adjust the winding die so that the die can wind coils of different specifications, they both adjust the die by changing the relative distance between the winding dies, that is, the distance in the length direction between the winding dies. When processing large-sized coils using the above adjustment method, a large spacing is required, and the overall volume of the device is large, greatly increasing the space occupation. Moreover, the large spacing easily causes the copper wire to wind and loosen, thus affecting the qualification rate and product quality of the final product. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a parametric adjustment mechanism for the winding device of a winding and embedding integrated machine that can automatically adjust the winding die, is convenient to adjust, and can effectively prevent the copper wire from winding and stretching after the adjustment is completed.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A parametric adjustment mechanism for the winding device of a winding and embedding integrated machine, including a frame. Inside the frame, there are a winding device, a wire feeding device, and a die adjustment device. Inside the winding device, there is a copper wire winding assembly. The copper wire winding assembly includes a driving shaft arranged inside the winding device. At the lower end of the driving shaft, there is a flying fork. Inside the flying fork, there is a wire passing groove. One end of the flying fork extends downward to form a winding head. Inside the flying fork, there is also a sliding plate. Inside the sliding plate, there is a winding die. The winding die includes a symmetrically arranged front winding die and a rear winding die. The winding dies are distributed in a stepped shape from top to bottom. The copper wire is wound around the winding die through the winding head. Inside the winding die, there is also a parametric adjustment mechanism, and the parametric adjustment mechanism is configured to perform parametric adjustment according to the shape of the workpiece to be processed.

[0008] The present invention is further configured as follows: Several mounting holes are provided at the top of the winding die. The sliding plate adjusts the shape of the winding die through the mounting holes. A wire die guide post is also provided on the sliding plate, and the sliding plate adjusts the distance between the front winding die and the rear winding die by sliding on the wire die guide post.

[0009] The present invention is further configured as follows: The parametric adjustment mechanism includes a spacing adjustment component arranged on the wire die guide post and a width adjustment component arranged on the winding die. The spacing adjustment component includes a front die adjustment post and a rear die adjustment post arranged on the wire die guide post. The front die adjustment post and the rear die adjustment post are configured to rotate in the wire die guide post and have opposite rotation directions. The width adjustment component includes a sliding groove arranged in the middle of the winding die, and the sliding groove is used to adjust the lateral distance between the two ends of the front winding die and the rear winding die.

[0010] Preferably, the ratio of the distance in the width direction of the mutually symmetric winding molds to the distance in the length direction of the mutually symmetric winding molds is 1:2.

[0011] The present utility model is further arranged such that: the flying fork is arranged in a "Y" shape within the winding device, and the angle at the corner of the flying fork is α, and 130° ≤ α ≤ 150°, and a pulley for the copper wire to pass through is provided within the flying fork.

[0012] By adopting the above technical solutions, the beneficial effects are as follows: 1. The coil to be processed is installed on the winding mold, the flying fork rotates outside the winding mold, and the copper wire is wound around the coil on the winding mold through the winding head on the flying fork. Moreover, the spacing of the winding mold is adjustable in shape within the copper wire winding assembly. By adjusting the distance in the length direction and the distance in the width direction of the winding mold, the overall perimeter of the winding mold is changed, greatly reducing the overall space occupied by the device, facilitating the operation of the staff, enabling the processing of components of different specifications, with simple operation and high automation.

[0013] 2. Further, in order to facilitate the adjustment of the shape of the winding mold, a spacing adjustment component is provided on the wire mold guide post and a width adjustment component is provided on the winding mold. The spacing adjustment component further includes a front mold adjustment post and a rear mold adjustment post provided on the wire mold guide post. The front mold adjustment post and the rear mold adjustment post are configured to rotate within the wire mold guide post and have opposite rotation directions. Specifically, when the wire mold guide post rotates in one direction, due to the opposite rotation directions of the front mold adjustment post and the rear mold adjustment post, the winding molds provided on the front mold adjustment post and the rear mold adjustment post move synchronously in opposite directions, realizing the relative approach or separation of the winding molds. And by providing a sliding groove in the middle of a single winding mold, the distance in the width direction of the winding mold can be adjusted through the sliding groove. By adjusting the distance in the length and width directions of the winding mold, the adjustment of the perimeter of the winding mold is realized.

[0014] 3. Meanwhile, for the parametric adjustment, that is, while ensuring that the perimeter of the winding mold remains unchanged, the aspect ratio of the winding mold is adjusted according to a distance distribution of 1:2. Generally speaking, since there are gaps in the length direction of the winding mold, during the winding process of the mold, the copper wire cannot be fixed on the mold and is prone to bending, entanglement, and loosening during the winding process, thus affecting the qualification rate of the finished product. Moreover, the larger the distance between the winding molds, the greater the probability of the copper wire being entangled and loosened. In the width direction of the winding mold, due to the obstruction of the stepped winding mold, the copper wire can be tightly wound around the winding mold, and the probability of entanglement and loosening is greatly reduced. Additionally, the distance detection element can accurately judge the length distance and width distance of the current winding mold and adjust them with the target data in the central control system, with a high degree of automation and convenient adjustment. And the winding mold is composed of 4 sections of stepped templates. To increase the rationality during the adjustment process of the winding mold and make the copper wire have a smaller deformation amount during winding, the adjustment parameter ranges of the 4 sections of the mold are 133 - 733, 171 - 775, 211 - 818, and 255 - 861 respectively.

[0015] 4. Also, during the adjustment process of the winding mold, the angle range of the corner of the flying fork is always between 130° and 150°. Generally speaking, during the winding process of the winding mold, if the angle at the corner is greater than 150° or the angle at the corner < 130°, it will cause the copper wire to be stretched, resulting in the copper wire breaking during the winding process and affecting the use effect. If the distance in the length direction of the winding mold is too large, the angle of the flying fork arranged above the winding mold will inevitably increase, causing the copper wire to be stretched. In this application, by synchronously adjusting the distance in the width direction of the winding mold, the interval distance between the winding molds is made smaller, and at the same time, it has a larger perimeter, so that the angle of the flying fork above the winding mold is within the set range, which can effectively prevent the stretching of the copper wire while meeting the processing standards and improve the production effect.

[0024] Moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0025] A parameterized adjustment mechanism for the wire winding device of a winding and embedding integrated machine, including a frame 1. Inside the frame 1, there is a wire winding device 2, a wire feeding device, and a mold adjustment device 3. Inside the wire winding device 2, there is a copper wire winding assembly 4. The copper wire winding assembly 4 includes a driving shaft 5 arranged inside the wire winding device 2. At the lower end of the driving shaft 5, there is a flying fork 6. Inside the flying fork 6, there is a wire passing groove 7. One end of the flying fork 6 extends downward to form a wire winding head 8. Inside the flying fork 6, there is also a sliding plate 9. Inside the sliding plate 9, there is a wire winding mold 10. The wire winding mold 10 includes a symmetrically arranged front wire winding mold 11 and a rear wire winding mold 12. The wire winding molds 10 are distributed in a stepped shape from top to bottom. The copper wire is wound around the wire winding mold 10 through the wire winding head 8. Inside the wire winding mold 10, there is also a parameterized adjustment mechanism 13. The parameterized adjustment mechanism 13 is configured to perform parameterized adjustment according to the shape of the workpiece to be processed.

[0026] By installing the coil to be processed on the wire winding mold 10, the flying fork 6 rotates outside the wire winding mold, and the copper wire is wound into the coil on the wire winding mold 10 through the wire winding head 8 on the flying fork 6. And the spacing of the wire winding mold 10 is adjustable in shape inside the copper wire winding assembly 4. By adjusting the distance in the length direction and the distance in the width direction of the wire winding mold 10, the overall perimeter of the wire winding mold 10 is changed, greatly reducing the overall space occupied by the device, facilitating the operation of the staff, realizing the processing of components of different specifications, with simple operation and high automation.

[0027] Further, in order to facilitate the adjustment of the wire winding mold 10, a number of mounting holes 14 are provided at the top of the wire winding mold 10. The sliding plate 9 adjusts the shape of the wire winding mold 10 through the mounting holes 14. On the sliding plate 9, there are also wire mold guide posts 15. The sliding plate 9 slides on the wire mold guide posts 15 to adjust the spacing between the front wire winding mold 11 and the rear wire winding mold 12.

[0028] The parameterized adjustment mechanism 13 includes a spacing adjustment component 16 arranged on the wire mold guide post 15 and a width adjustment component 17 arranged on the wire winding mold 10. The spacing adjustment component 16 includes a front mold adjustment post 18 and a rear mold adjustment post 19 arranged on the wire mold guide post 15. The front mold adjustment post 18 and the rear mold adjustment post 19 are configured to rotate in the wire mold guide post 15 and have opposite rotation directions. The width adjustment component 17 includes a sliding groove 20 arranged in the middle of the wire winding mold 10. The sliding groove 20 is used to adjust the lateral distance between the two ends of the front wire winding mold 11 and the rear wire winding mold 12.

[0029] Preferably, the ratio of the distance in the width direction of the symmetrically arranged wire winding molds 10 to the distance in the length direction of the symmetrically arranged wire winding molds 10 is 1:2.

[0030] By providing a spacing adjustment assembly 16 on the wire die guide post 15 and a width adjustment assembly 17 on the wire winding die 10, the spacing adjustment assembly 16 further includes a front die adjustment post 18 and a rear die adjustment post 19 provided on the wire die guide post 15. The front die adjustment post 18 and the rear die adjustment post 19 are configured to rotate in the wire die guide post 15 and in opposite rotation directions. Specifically, when the wire die guide post 15 rotates in one direction, due to the opposite rotation directions of the front die adjustment post 18 and the rear die adjustment post 19, the wire winding die 10 provided on the front die adjustment post 18 and the rear die adjustment post 19 moves synchronously in opposite directions, realizing the relative approach or separation of the wire winding die 10. And by providing a chute 20 in the middle of a single wire winding die 10, the distance in the width direction of the wire winding die 10 can be adjusted through the chute 20. By adjusting the distances in the length and width directions of the wire winding die 10, the perimeter of the wire winding die 10 is adjusted.

[0031] Meanwhile, for the parametric adjustment, that is, while ensuring that the perimeter of the wire winding die 10 remains unchanged, the aspect ratio of the wire winding die 10 is adjusted according to a distance distribution of 1:2. Generally speaking, since there is a gap in the length direction of the wire winding die 10, during the process of winding the wire on the die, the copper wire cannot be fixed on the die, and it is easy to bend, entangle, and loosen during the winding process, thus affecting the qualified rate of the finished product. Moreover, the larger the spacing between the wire winding dies 10, the greater the probability of the copper wire being entangled and loosened. In the width direction of the wire winding die 10, due to the obstruction of the stepped wire winding die 10, the copper wire can be tightly wound on the wire winding die 10, and the probability of entanglement and loosening is greatly reduced. And the distance detection element can accurately judge the length distance and width distance of the current wire winding die 10 and adjust them with the target data in the central control system, with a high degree of automation and convenient adjustment. And the wire winding die is composed of 4 stepped templates. In order to increase the rationality during the adjustment process of the wire winding die and make the copper wire have a smaller deformation amount during winding, the adjustment parameter ranges of the 4 dies are 133 - 733, 171 - 775, 211 - 818, and 255 - 861 respectively.

[0032] Moreover, the flying fork 6 is arranged in a "Y" shape in the wire winding device 2, and the angle at the corner of the flying fork 6 is α, and 130° ≤ α ≤ 150°, and a pulley 21 for the copper wire to pass through is provided in the flying fork 6.

[0033] Specifically, referring to Figure 5 , when the perimeter of the wire winding die 10 is constant, the size of the element to be processed is the same, and the size of the flying fork 6 is the same, due to the relatively large length of the traditional wire winding die 10, the required size and the angle at the corner of the flying fork 6 also increase accordingly, resulting in an increase in the overall occupied space and prone to copper wire entanglement and copper wire stretching.

[0034] During the adjustment of the winding die 10, the angle range of the corner of the flying fork 6 is always between 130° and 150°. Generally speaking, during the winding of the winding die 10, if the angle at the corner is greater than 150° or the angle at the corner < 130°, it will cause the copper wire to be stretched, resulting in the breakage of the copper wire during winding and affecting the use effect. If the distance in the length direction of the winding die 10 is too large, the angle of the flying fork 6 arranged above the winding die 10 will inevitably increase, causing the copper wire to be stretched. In this application, by synchronously adjusting the distance in the width direction of the winding die 10, the spacing distance between the winding dies 10 is made smaller, and at the same time, it has a larger circumference, so that the angle of the flying fork 6 above the winding die 10 is within the set range, effectively preventing the stretching of the copper wire while meeting the processing standard and improving the production effect.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
