Description

Technical Field

[0001] The present invention relates to the technical field of coil winding devices, in particular to a square wire inductor winding device. Background Art

[0002] A coil usually refers to a ring-shaped wire winding. The most common coil applications include motors, inductors, transformers, and loop antennas. The inductor coil needs to be wound into a coil by a winding machine. Therefore, when winding, the wire needs to be fixed and then rotated to wind the coil. There is a new type of inductor coil 100 in the prior art, such as Figure 9 As shown, the inductor 100 is wound with a square wire and has a protrusion 110 on the top, which is used for welding or connecting to other structures. The winding machine in the prior art generally clamps the wire and then rotates it for winding. For example, an inductor winding device disclosed in CN201920970362.1 includes a mounting table 1, a servo motor 4, a winding rod 91, a left fixed disk 31, a right fixed disk 32, a wire arrangement device 6, a fixed clamping jaw 8b, a movable clamping jaw 8a, a push barrel 5 and a discharge chute 83. When the above-mentioned inductor coil winding device is winding the coil, it fixes one end of the copper wire on the left fixed disk through a fixed clamp, and the other end is driven by the wire arrangement device to start winding the inductor coil on the winding rod under the drive of the motor. At the same time, the mechanical rodless cylinder moves the winding head to the right on the winding rod; after winding a certain number of turns, the movable clamp clamps the other end on the right fixed disk, and then the cutter moves to the left and cuts the copper wire on the other end, and the push barrel feeds the coil to the left.

[0003] However, a winding machine of this structure is not suitable for the inductor coil 100 , and due to the presence of the protrusion 110 , the protrusion 110 and the entire coil need to be fixed during winding, and the winding line also needs to be avoided, making it difficult to use existing winding devices for winding. Summary of the Invention

[0004] In view of this, the present invention provides a square wire inductor winding device to solve the above technical problems.

[0005] A square wire inductor winding device is provided for winding an inductor coil made of square wire and having a protrusion on its top. The device comprises a bracket, a lower clamping mechanism mounted on the bracket, and an upper clamping mechanism mounted on the bracket. The lower clamping mechanism comprises a lower sleeve mounted on the bracket, a lower rotating shaft rotatably mounted on the lower sleeve, a push rod slidably mounted on the lower rotating shaft, and a push block mounted on one end of the push rod. One end of the push block is mounted on a side wall of the push rod, and the other end has a protrusion mounted on the other end to abut against the protrusion. The upper clamping mechanism comprises an upper sleeve mounted on the bracket, an upper rotating shaft rotatably mounted on the upper sleeve, a die head mounted on one end of the rotating shaft, and a locking assembly mounted on the die head. The die head is provided with a mounting slot on its side wall and a latching slot on the end surface of the die head facing the lower clamping mechanism. The locking assembly includes a rotating rod, a locking block disposed at one end of the rotating rod, and a spring disposed between the rotating rod and the mounting slot. The middle portion of the rotating rod is rotatably connected to the inner wall of the mounting slot, and the locking block engages the side wall of the abutment block. After the abutment block moves downward, the rotating rod rotates under the action of the spring, causing the locking block to engage the protrusion.

[0006] Furthermore, the lower clamp mechanism also includes a first driving device arranged on the bracket and a guide structure arranged on the lower sleeve. The first driving device drives the lower shaft to rotate and drives the push rod to move up and down.

[0007] Furthermore, the guide structure is arranged on an end surface of the lower sleeve facing the upper clamp mechanism and is located on one side of the lower sleeve. The guide structure includes an inclined surface arranged on one side of the lower sleeve and two spaced-apart limit blocks.

[0008] Furthermore, the lower sleeve is hollow and has a sleeve through hole in the center. The central axis of the lower rotating shaft is provided with an axial through hole and a push block through hole arranged on one side of the axial through hole. The axial through hole is used to accommodate the push rod, and the push block through hole is connected to the axial through hole and is used to accommodate the push block.

[0009] Furthermore, the square wire inductor winding device also includes an unlocking mechanism arranged on the bracket, the unlocking mechanism includes a mounting plate arranged on the bracket, a driving cylinder arranged on the mounting plate, and an unlocking block arranged on the driving cylinder, and the output direction of the driving cylinder is close to or away from the upper clamp mechanism.

[0010] Furthermore, the upper clamping mechanism also includes an axial column movably inserted on the upper rotating shaft, and a second driving device arranged on the bracket. The mold head is provided at one end of the upper rotating shaft facing the lower clamping mechanism, and the other end is connected to the second driving device.

[0011] Furthermore, the locking assembly also includes a roller arranged at the other end of the rotating rod.

[0012] Compared with the prior art, the square wire inductor winding device provided by the present invention has one end of the abutment block arranged on the side wall of one end of the abutment rod and located in the through hole of the abutment block, and the other end is provided with a protrusion and is used to abut the protrusion of the inductor coil. The abutment rod and the abutment block rotate together with the lower rotating shaft and can move up and down in the axial through hole. The locking assembly includes a rotating rod, a buckle block, and a spring. The middle position of the rotating rod is rotatably connected to the inner wall of the mounting groove, and the buckle block is in contact with the side wall of the abutment block. After rotating half a circle, the abutment block moves downward, and the buckle block, which was originally in contact with the side wall of the abutment block, will automatically rotate under the action of the spring after the abutment block is no longer blocked, so that the rotating rod will automatically rotate under the action of the spring and the buckle block will buckle the protrusion, thereby realizing the winding of the inductor coil, while also ensuring the fixing effect and avoiding the wire, and will not affect the normal operation of the winding.

[0022] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0023] like Figures 1 to 9 , which is a schematic structural diagram of the square wire inductor winding device provided by the present invention. The square wire inductor winding device includes a bracket 10, a lower clamping mechanism 20 disposed on the bracket 10, an unlocking mechanism 30 disposed on the bracket 10, and an upper clamping mechanism 40 disposed on the bracket 10. It is conceivable that the square wire inductor winding device also includes other functional modules, such as a rotating component and a moving component, etc., which are well known to those skilled in the art and will not be described in detail here.

[0024] First of all, it should be explained that the square wire inductor winding device is used to wind the inductor coil 100. The inductor coil 100 is wound by a square wire and has a protrusion 110 on the top. The protrusion 110 is used for welding or connecting with other structures. The inductor coil 100 should be existing technology and will not be described in detail.

[0025] The bracket 10 is U-shaped and is used for the above-mentioned functional components. Therefore, the bracket 10 is provided with a variety of functional structures, such as screws, bolts, through holes, etc. to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs and will not be described in detail one by one here.

[0026] The lower clamp mechanism 20 includes a lower sleeve 21 arranged on the bracket 10, a guide structure 22 arranged on the lower sleeve 21, a lower rotating shaft 23 rotatably arranged on the lower sleeve 21, a push rod 24 slidably inserted on the lower rotating shaft 23, a push block 25 arranged at one end of the push rod 24, and a first driving device 26 arranged on the bracket 10.

[0027] The lower sleeve 21 is hollow and has a sleeve through hole 212 at its center. The sleeve through hole 212 is used to dispose the lower rotating shaft 23 .

[0028] The guide structure 22 is arranged on an end surface of the lower sleeve 21 facing the upper clamp mechanism 40 and is located on one side of the lower sleeve 21. The guide structure 22 is used to guide the U-shaped wire being transported. The guide structure 22 includes an inclined surface 221 arranged on one side of the lower sleeve 21 and two limit blocks 222 arranged at intervals.

[0029] The lower rotating shaft 23 is arranged to rotate within the sleeve through hole 212. One end of the lower rotating shaft 23 is connected to the first driving device 26 and is driven to rotate by the first driving device 26, and the other end is flush with the opening of the sleeve through hole 212. It is conceivable that in order to support the rotation of the lower rotating shaft 23, a plurality of bearings are provided on the lower rotating shaft 23.

[0030] The lower rotating shaft 23 has a central through hole 231 extending therethrough, and a supporting block through hole 232 disposed on one side of the central through hole 231 .

[0031] The axial through hole 231 is used to accommodate the axial column in the upper fixture and the abutting rod 24 . The abutting block through hole 232 is communicated with the axial through hole 231 and is used to accommodate the abutting block 25 .

[0032] One end of the push rod 24 is connected to the first driving device 26, and is driven by the first driving device 26 to move up and down along the axial through hole 231. The other end is inserted into the sleeve through hole 212 and is provided with the push block 25. One end of the push block 25 is set on the side wall of one end of the push rod 24 and is located in the push block through hole 232. The other end is a protrusion and is used to resist the protrusion 110 of the inductor coil. The push rod 24 and the push block 25 rotate together with the lower rotating shaft 23 and can move up and down in the axial through hole 231. The lower clamp mechanism 20 needs to cooperate with the upper clamp mechanism 40 for winding. The specific description will be explained below in conjunction with the upper clamp mechanism 40.

[0033] The unlocking mechanism 30 includes a mounting plate 31 mounted on the bracket 10, a driving cylinder 32 mounted on the mounting plate 31, and an unlocking block 33 mounted on the driving cylinder 32. The output direction of the driving cylinder 32 moves toward or away from the upper clamping mechanism 40, thereby driving the unlocking block 33 to unlock the clamp. A detailed description will be given below in conjunction with the upper clamping mechanism 40.

[0034] The upper clamp mechanism 40 includes an upper sleeve 41 arranged on the bracket 10, an upper rotating shaft 42 rotatably arranged on the upper sleeve 41, a mold head 43 arranged at one end of the upper rotating shaft 42, a locking assembly 44 arranged on the mold head 43, a central column 45 movably inserted on the upper rotating shaft 42, and a second driving device 46 arranged on the bracket 10.

[0035] The upper sleeve 41 is hollow and is used to pass through the upper rotating shaft 42. The die head 43 is provided on one end of the upper rotating shaft 42 facing the lower clamping mechanism 20, and the other end is connected to and rotated by the second driving device 46. It is conceivable that the upper rotating shaft 42 needs to rotate during winding and move upward as the number of wound coils increases. Therefore, a bearing and a sleeve are provided between the upper rotating shaft 42 and the upper sleeve 41 to support the rotation and vertical movement of the upper rotating shaft 42.

[0036] The mold head 43 is provided with a mounting groove 431 located on a side wall of the mold head 43 , and a clamping groove 432 provided on an end surface of the mold head 43 facing the lower clamp mechanism 20 .

[0037] The mounting groove 431 is connected to the snap-fit ​​groove 432 . The mounting groove 431 is used to set the locking assembly 44 . The snap-fit ​​groove 432 is set on an end surface of the mold head 43 facing the lower clamp mechanism 20 and is used to accommodate the protrusion 110 during winding.

[0038] The locking assembly 44 includes a rotating rod 441, a locking block 442 at one end of the rotating rod 441, a roller 443 at the other end of the rotating rod 441, and a spring 444 disposed between the rotating rod 441 and the mounting slot 431. The middle portion of the rotating rod 441 is rotatably connected to the inner wall of the mounting slot 431, allowing the rotating rod 441 to swing. When free, the spring 444 abuts against one end of the roller 443, causing the rotating rod 441 to rotate. During winding, the locking block 442, under the action of the spring 444, engages the protrusion 110 within the engaging slot 432, automatically securing the wire during winding. Before winding, the locking block 442 engages the abutting block 25, securing the wire during the first half of winding. Thereafter, the locking block 442 secures the wire. The specific reasons and process will be explained below in conjunction with the winding process. The roller 443 faces the unlocking mechanism 30 and serves to provide a guide. When unlocking is required, the driving cylinder 32 drives the unlocking block 33 toward and pushes one end of the rotating rod 441, causing the rotating rod 441 to rotate and the spring 444 to compress. This causes the end of the locking block 442 to lift up, thereby no longer locking the inductor 100.

[0039] One end of the shaft column 45 is connected to the second driving device 46, and the other end is used to be inserted into the shaft through hole 231 during mold closing and winding, so as to pass through the inductor 100, so that the shaft column 45 serves as the center column of the winding, and the wire is wound around the shaft column 45 to form a circle.

[0040] The second driving device 46 is a multi-directional moving device, and is used to drive the rotating shaft 42 to rotate and move up and down and drive the shaft column 45 to move up and down. It should be existing technology and will not be described here in detail.

[0041] Before winding, an external device will bend a square wire into a U-shape and press out the protrusion 110 through a mold to form a winding blank 200. One end of the winding blank 200 is connected to a wire feeding device to continuously feed the wire during winding. The winding blank 200 should be prior art and will not be described in detail here. During winding, the upper and lower clamping mechanisms 40 and 20 first clamp the winding blank 200 so that the protrusion 110 is located in the clamping groove 432. Then, the support block 25 moves up to support the protrusion 110, and the axis column 45 is inserted into the axis through hole 231, thereby fixing the winding blank 200 and determining the axis. The buckle block 442 is engaged with the side wall of the support block 25 under the action of the spring 444. The upper and lower rotating shafts 42 and 23 then rotate synchronously. After half a turn, the abutting block 25 moves downward. The buckle block 442, which was originally in contact with the side wall of the abutting block 25, is no longer blocked by the abutting block 25. The rotating rod 441 automatically rotates under the action of the spring 444, causing the buckle block 442 to buckle the protrusion 110. As the rotation continues, the wire is wound around the shaft 45. After winding is completed, the locking assembly 44 is directly facing the unlocking mechanism 30 and is unlocked by it, allowing the coil to be removed.

[0042] Because the shaft begins to rotate suddenly, the force exerted is significant, making it difficult to securely lock the shaft with just the locking assembly 44. Therefore, during the first half of the rotation, the abutting block 25 pushes upward to secure the protrusion 110, providing a greater abutting force. This also serves to clear the wire. After half a rotation, the winding position will be below the protrusion 110, and the abutting block 25 moves downward to clear the wire. The locking block 442 then automatically locks the shaft, preventing any disruption to the winding process.

[0043] Compared with the prior art, the square wire inductor winding device provided by the present invention has one end of the push block 25 disposed on the side wall of one end of the push rod 24 and located in the push block through hole 232, and the other end is provided with a protrusion and is used to push against the protrusion 110 of the inductor coil. The push rod 24 and the push block 25 rotate together with the lower shaft 23 and can move up and down in the axial through hole 231. The locking assembly 44 includes a rotating rod 441, a buckle block 442, and a spring 444. The middle position of the rotating rod 441 is rotatably connected to the inner wall of the mounting groove 431, and the buckle block 442 is in contact with the side wall of the push block 25. After rotating half a circle, the abutting block 25 moves downward, and the buckle block 442, which was originally in contact with the side wall of the abutting block 25, is no longer blocked by the abutting block 25. The rotating rod 441 will automatically rotate under the action of the spring 444 and make the buckle block 442 buckle the protrusion 110, thereby realizing the winding of the inductor coil 100, while also ensuring the fixing effect and avoiding the wire, and will not affect the normal work of the winding.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
