Description

Technical Field

[0001] The present application relates to a winding device, and in particular to an inductor winding device. Background Art

[0002] In the manufacturing process of inductors, winding the wire on the inductor core is a delicate and critical step, which directly affects the performance of the inductor and the overall efficiency of production. Traditional winding operations rely on manual work, from the clamping of the wire to the completion of the winding, and then to the final pick-up and placement, all require manual operation, which is not only inefficient, but also difficult to meet the needs of automated production. In order to improve the winding efficiency, modern manufacturing has introduced automated fixtures, using unidirectional single-wire or unidirectional double-wire winding methods for automated winding.

[0003] However, in this winding method, one end of the coil may be pressed into the inner layer by other coils after winding, which does not meet the use requirements of all inductor products. To solve this problem, technicians are required to perform additional processes during the production process to ensure that both ends of the winding coil are located at the outermost layer of the inductor core to meet specific product requirements. This not only increases the complexity of the winding process, but also affects production efficiency. Utility Model Content

[0052] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0053] The present utility model provides an inductor winding device, please refer to Figure 1 The inductor winding device comprises a clamping unit and a winding unit.

[0054] The clamping unit has a plurality of clamping rollers, which are arranged to match the diameter of the inductor core 2 and are used for clamping the inductor core 2 and driving the inductor core 2 to rotate around the longitudinal axis.

[0055] The winding unit includes a mounting frame 30, a winding coil assembly and a transmission assembly 4. The mounting frame 30 is movably mounted with a movable frame 302. The movable frame 302 is rotatably connected with a pressing ring 31. The winding coil assembly 32 includes a winding coil and a pay-off roller 322. The winding coil assembly 32 sleeves the inductor core 2 therein and rotates around the transverse axis. The pay-off roller 322 is rotatably connected to the inner wall of the winding coil assembly 32. The pay-off roller 322 rotating with the winding coil can pass through the inductor core 2. The transmission assembly 4 includes a plurality of friction wheels 42 and a friction belt 41. The friction wheel 42 is externally connected with a driving device. The friction belt 41 is sleeved and tensioned on the outer wall of the friction wheel 42. The pressing ring 31 abuts against the winding coil and presses the winding coil to the friction belt 41.

[0056] When the winding coil rotates around the transverse axis under the action of the transmission assembly 4, the inductor wire is pulled out from the pay-off roller 322 and is wound around the inductor core 2 along the rotation trajectory of the winding coil, thereby achieving its tight winding on the inductor core 2. At the same time, the clamping roller drives the inductor core 2 to rotate around the longitudinal axis, so that the wire can be wound around the inductor core 2 in turn and evenly.

[0057] Specifically,

[0058] Clamping unit, see Figure 1-Figure 3 The clamping unit includes a clamping roller and a base 50 . The clamping roller is arranged to match the diameter of the inductor core 2 , and is used to clamp the inductor core 2 and drive the inductor core 2 to rotate around the longitudinal axis. The clamping roller is installed on the base 50 .

[0059] The base 50 is provided with a plurality of through grooves 502 matching the clamping roller. A convex portion 501 is provided at the top of both sides of the through groove 502. The distance between the two convex portions 501 is set to match the clamping roller. That is, the distance between the two convex portions 501 is equal to the diameter of the shaft body 14 of the clamping roller.

[0060] The clamping roller includes a roller body 13, a shaft body 14 and a fixing ring 15. There are multiple clamping rollers. A clamping groove 130 is opened on the side wall of each roller body 13 along the circumference of the roller body 13. The clamping groove 130 surrounds the inductor core 2. The top end of the shaft body 14 passes through the roller body 13, and the shaft body 14 is fixedly installed on the roller body 13 through the fixing ring 15. The clamping roller is divided into an active clamping roller 11 and a driven clamping roller 10. Among them,

[0061] The active clamping roller 11 also has a first motor. The first motor includes a mounting seat 161 and a first motor body 160. The first motor body 160 is arranged in the mounting seat 161. The active clamping roller 11 is arranged above the mounting seat 161. The bottom end of the shaft body 14 passes through the mounting seat 161 and is connected to the first motor body 160. The first motor body 160 drives the shaft body 14 to rotate, thereby driving the active clamping roller 11 to rotate.

[0062] At least two driven clamping rollers 10 are provided. In order to ensure the winding accuracy of the inductor coil, the installation positions of the two driven clamping rollers 10 can be set first according to the diameter size of the inductor coil, and then the installation position of the active clamping roller 11 can be set. Therefore, the opening position of the through groove in the base can be set based on the pre-installation position of the driven clamping roller 10 as the starting point and extending to the two ends of the base 50 in reverse. A first limiting assembly 12 is provided at the bottom end of the shaft body 14 of each driven clamping roller 10. The first limiting assembly 12 includes a first limiting ring 121 and a rotating block 120. The rotating block 120 is arranged between the first limiting ring 121 and the roller body 13.

[0063] The first limiting ring 121 is connected to the bottom end of the shaft body 14 of the driven clamping roller 10. The first limiting ring 121 is configured to match the through groove 502. That is, the height of the first limiting ring 121 is equal to the groove depth of the through groove 502.

[0064] The rotating block 120 penetrates through the top end of the shaft body 14 of the driven clamping roller 10 and is threadedly connected to the shaft body 14 .

[0065] When the first limit ring 121 is clamped in the through groove 502, by rotating the rotating block 120 clockwise, the distance between the rotating block 120 and the first limit ring 121 can be made closer and closer, thereby limiting the movement of the driven clamping roller 10 along the through groove 502; conversely, the distance between the rotating block 120 and the first limit ring 121 becomes farther and farther.

[0066] In addition, connecting parts 162 are respectively provided at both ends of the bottom of the mounting seat 161. The connecting part 162 is connected to the top of the base 50, and a through hole matching the through slot 502 is opened in the connecting part 162. That is, the through hole is aligned with the through slot 502, and the diameter of the through hole is equal to the distance between the two protrusions 501. By providing a second limiting component 163 at the bottom end of the active clamping roller 11, the mounting seat 161 is fixedly installed on the base 50. The second limiting component 163 includes a second limiting ring 1630, a connecting column 1632 and a rotating ring 1631.

[0067] The connecting column 1632 is provided to match the through hole. The bottom end of the connecting column 1632 passes through the through hole and is provided in the through groove 502. At this time, the second limiting ring 1630 is connected to the bottom end of the connecting column 1632. The second limiting ring 1630 is provided to match the through groove 502. That is, the height of the second limiting ring 1630 is equal to the groove depth of the through groove 502. The rotating ring 1631 is threadedly connected to the top end of the connecting column 1632.

[0068] When the second limiting ring 1630 is clamped in the through groove 502, by rotating the rotating ring 1631 clockwise, the distance between the rotating ring 1631 and the second limiting ring 1630 can be made closer and closer, thereby limiting the movement of the active clamping roller 11 along the through groove 502; conversely, the distance between the rotating ring 1631 and the second limiting ring 1630 becomes farther and farther.

[0069] Taking two driven clamping rollers 10 as an example, the base 50 can be designed as two separate bases 50. The two bases 50 can be installed on the bottom plate 51 in parallel with each other. The installation process of the clamping unit is as follows: first, the positions of the two bases 50 and the through slots 502 are set according to the diameter size of the inductor coil. Then, a driven clamping roller 10 is installed at each base 50 according to the position of the through slot 502. Among them, after the first limiting ring 121 is inserted into the through slot 502 and the shaft 14 of the driven clamping roller 10 slides to a suitable position along the direction of the through slot 502, the rotating block 120 is rotated clockwise so that it and the first limiting ring 121 clamp the convex portion 501, thereby realizing the sliding restriction of the driven clamping roller 10.

[0070] Adjust the installation position of the active clamping roller 11 on the base 50: the second limiting ring 1630 is inserted into the through groove 502 so that the connecting column 1632 is slidably connected to the protrusion 501. Align the through hole of the mounting seat 161 with the connecting column 1632 to achieve the positioning installation of the first motor at the base 50. After the roller body 13 of the active clamping roller 11 is connected to the first motor body 160, the inductor core 2 can be built into the space enclosed by the active roller body 11 and the driven roller body 10. Then, the space enclosed by the clamping roller is matched with the diameter of the electromagnetic coil by sliding the connecting column 1632. Turn the rotating circle 1631 clockwise so that it and the second limiting ring 1630 clamp the protrusion 501, thereby achieving the sliding restriction of the active clamping roller 11.

[0071] The working principle of the clamping unit is as follows: the first motor body 160 is started to drive the roller body 13 of the active clamping roller 11 to rotate. Under the cooperation of the active clamping roller 11 and the driven clamping roller 10, the inductor core 2 is driven to rotate.

[0072] The winding unit includes a mounting frame 30, a winding coil assembly 32 and a transmission assembly 4. A pressing ring 31 is rotatably connected to the top of the mounting frame 30. The pressing ring 31 presses the winding coil assembly 32 to the transmission assembly 4 to limit the movement of the winding coil assembly 32 in the plane extension direction. At the same time, the transmission assembly 4 drives the winding coil assembly 32 to rotate.

[0073] The mounting frame 30 includes a fixed frame body 301 and a movable frame body 302. The plane extension direction of the fixed frame body 301 is parallel to the extension direction of the through slot 502. One end of the movable frame body 302 is bolted to the top of the fixed frame body 301, so as to achieve the angle adjustment of the movable frame body 302. A pressing ring 31 is rotatably connected to the side wall of the proximal end of the other end of the movable frame body 302.

[0074] The coil assembly 32 includes a coil and a pay-off roller 322. The plane extension direction of the coil is parallel to the plane extension direction of the fixed frame 301. The pay-off roller 322 is connected to the inner wall of the coil.

[0075] The winding coil is composed of two half coils. Each half coil is a semicircular ring structure. One end of the two half coils is connected by a hinge, so that the winding coil can be flexibly opened or closed, so as to facilitate the insertion of the inductor core 2 therein. The other end of the two half coils is connected with a detachable clamping block 321. When the inductor core 2 is inserted into the winding coil, the clamping block 321 is installed at the other end of the half coils at both ends to maintain the closed state of the winding coil during the winding process.

[0076] The two ends of the pay-off roller 322 are rotatably connected to the inner wall of the winding coil through the fixing pin 323. The pay-off roller 322 is provided to match the inductor core 2. That is, when rotating around the winding coil, the pay-off roller 322 can pass through the ring of the inductor core 2. The inductor wire is wound around the outer wall of the pay-off roller 322.

[0077] The transmission assembly 4 includes a plurality of friction wheels 42, a second motor 43 and a friction belt 41. A plurality of friction wheels 42 are installed near the bottom of the fixed frame 301. The friction belt 41 is sleeved and tensioned on the outer wall of the driving end of the friction wheel 42 and the second motor 43. By adjusting the angle of the movable frame 302 and then connecting the movable frame 302 to the fixed frame 301 by bolts, the pressure ring 31 is abutted against the winding coil and the winding coil is pressed against the outer wall of the friction belt 41, thereby limiting the movement of the winding coil along the plane extension direction. After the second motor 43 is transmitted to the friction belt 41, the friction wheel 42 is driven to rotate by the friction belt 41, and then the friction between the friction belt 41 and the winding coil is used to drive the winding coil to rotate.

[0078] The working principle of this embodiment is as follows:

[0079] After the second motor 43 is transmitted to the friction belt 41, the friction belt 41 drives the friction wheel 42 to rotate, and then the friction between the friction belt 41 and the winding coil is used to drive the winding coil to rotate around the transverse axis. At this time, the inductor wire is pulled out from the pay-off roller 322, and the inductor wire is wound on the inductor core 2 along the rotation track of the winding coil, thereby realizing the tight winding of the inductor wire on the inductor core 2.

[0080] At the same time, the first motor body 160 is started to drive the roller body 13 of the active clamping roller 11 to rotate. With the cooperation of the active clamping roller 11 and the driven clamping roller 10, the inductor core 2 is driven to rotate around the longitudinal axis, so that the inductor wire can be wound around the inductor core 2 in turn and uniformly along the circumference of the inductor core 2. The present application can realize the winding of the coil while making the starting end and the ending end of the coil both located at the outermost layer of the inductor core 2 to meet specific product requirements, simplifying the winding process of the inductor coil and greatly improving production efficiency.
