Description

Technical Field

[0001] This invention relates to the field of inductor manufacturing technology, and in particular to an automated winding processing equipment for inductor manufacturing. Background Technology

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, which only impedes changes in current. If there is no current flowing through the inductor, it will try to impede the current from flowing through it when the circuit is closed; if there is current flowing through the inductor, it will try to maintain the current when the circuit is open. An inductor is generally composed of a frame, winding, shielding, encapsulation material, and magnetic core. The winding refers to a set of coils with a specified function. The most common winding is a spiral winding wire wound around the outer wall of an iron core.

[0003] A search revealed that CN114420449A, a patented automated winding processing device for inductor manufacturing, includes a second forward and reverse motor, a sliding block, a first cone, and a second cone comprising a base, a support rod, a support seat, a fixing unit, and a winding unit. The support seat is mounted on the upper center of the base via the support rod. The fixing unit and the winding unit are installed between the base and the support seat. This invention ensures the tightness of the winding wires on the outer wall of the iron core, preventing the winding wires from falling off the iron core and affecting its use. However, the invention has some shortcomings: it can only process windings on four iron cores at a time, resulting in low winding efficiency. Furthermore, due to limitations in the height of the support rod and the size of the fixing seat, it can only process windings on iron cores with a fixed diameter and a limited height, making the processing equipment highly limited. Therefore, an automated winding processing device for inductor manufacturing is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an automated winding processing equipment for inductor manufacturing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automated winding processing device for inductor manufacturing includes a processing table. The bottom of the processing table is fixedly connected to multiple support legs. The top of the processing table is rotatably connected to a row of rotating shafts via bearings. The distance between each pair of adjacent rotating shafts is equal. A clamping plate is coaxially fixedly connected to the upper end of each rotating shaft. The clamping plate has three through moving slots arranged in a circular array. A clamping block is slidably connected in each moving slot. A winding mechanism is provided on the processing table.

[0006] In the aforementioned automated winding processing equipment for inductor manufacturing, the winding mechanism includes a control disk. Symmetrically distributed limiting slots are formed on both sides of the sliding slot of each moving slot. Limiting blocks are fixedly connected to both sides of the clamping block. The two limiting blocks are slidably connected to the limiting slots on both sides. A threaded connection section is formed at one end of the rotating shaft near the clamping disk. The control disk is threadedly connected to the threaded connection section on the rotating shaft. The control disk and the clamping disk are coaxially arranged. Three arc-shaped slots are formed in a circular array on the control disk. A connecting rod with a circular cross-section is fixedly connected to the bottom of each clamping block. The three connecting rods are slidably connected to the three arc-shaped slots respectively.

[0007] In the aforementioned automated winding processing equipment for inductor manufacturing, a row of wire roller placement frames is fixedly connected at equal distances on the processing table away from the clamping plate. The number and position of the wire roller placement frames correspond to the clamping plate, and each wire roller placement frame is rotatably connected to a wire feeding roller.

[0008] In the aforementioned automated winding processing equipment for inductor manufacturing, multiple sliding rods are slidably connected through the middle of the processing table. Each sliding rod has a guide rod fixedly connected to its upper end, and a lifting plate is fixedly connected to the lower end of all the guide rods. An installation groove is provided at the bottom of the processing table, and a forward and reverse motor is installed and fixedly mounted on the top wall of the installation groove. The output shaft of the forward and reverse motor is coaxially fixedly connected to a threaded shaft, and the threaded shaft is threadedly connected to the lifting plate.

[0009] In the aforementioned automated winding processing equipment for inductor manufacturing, the lower end of each rotating shaft passes through the processing table and is coaxially fixedly connected to a sprocket. Multiple sprockets are jointly fitted with a chain. The lower end of the threaded shaft is coaxially fixedly connected to a drive wheel. The lower end of one of the rotating shafts is coaxially fixedly connected to a driven wheel. The drive wheel and the driven wheel are jointly fitted with a transmission belt.

[0010] In the aforementioned automated winding processing equipment for inductor manufacturing, each guide rod is fixedly connected to a mounting frame at one end near the pay-off roller. A first guide wheel is rotatably connected to the mounting frame via a pin, and two symmetrically distributed second guide wheels are rotatably connected to one end of each guide rod near the clamping disc via a pin.

[0011] In the aforementioned automated winding processing equipment for inductor manufacturing, a fixing block is fixedly connected to the top of one of the clamping blocks on each clamping plate, and a threaded button is threadedly connected to the side of the fixing block away from the center of the clamping plate.

[0012] In the aforementioned automated winding processing equipment for inductor manufacturing, the transmission ratio between the driving wheel and the driven wheel is 3:1, and each clamping block has anti-slip texture on the side near the center of the clamping disk.

[0013] The present invention has the following advantages: 1. The clamping disc in this invention can clamp iron cores of different diameters and heights, increasing the applicability of the processing equipment. During the clamping process, only three clamping blocks can slide towards the center simultaneously. While the iron core is being clamped, it is pushed and fixed in the center position of the clamping disc by the clamping blocks. After the control disc rotates to the designated position, a threaded self-locking mechanism is formed to ensure the stability of the iron core clamping. Furthermore, during the processing, the fixing and unloading operations of the entire iron core are simple and quick, improving the winding efficiency. 2. This invention can process multiple iron cores at once, further improving the winding efficiency of the iron cores. During the iron core's rotation and winding process, the lifting plate that moves upward through the screw will push multiple sliding rods to rise at a uniform speed, so that the guide rod gradually moves the wire feeding to the iron core, making the winding wire on the iron core spirally wound, ensuring the winding quality. 3. The present invention fixes one end of the winding wire with the threaded button and the fixing block and rotates with the iron core to ensure the tightness of the winding wire on the outer wall of the iron core and prevent it from falling off. The winding wire that is pulled out from the pay-off roller in a bent state will be straightened by the squeezing and adjustment of the first guide wheel and the second guide wheel, so that it can be better wound on the iron core.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0017] Reference Figure 1-7 An automated winding processing device for inductor manufacturing includes a processing table 1. Multiple support legs 2 are fixedly connected to the bottom of the processing table 1. A row of rotating shafts 3 are rotatably connected to the top of the processing table 1 via bearings. The distance between each pair of adjacent rotating shafts 3 is equal. A clamping plate 4 is coaxially fixedly connected to the upper end of the rotating shaft 3. Three through moving slots 5 are opened on the clamping plate 4 in a circular array. A clamping block 6 is slidably connected in each moving slot 5. A winding mechanism is provided on the processing table 1.

[0018] The winding mechanism includes a control disk 10. Each moving slot 5 has symmetrically distributed limiting slots 7 on both sides of the slot wall. Both sides of the clamping block 6 are fixedly connected to limiting blocks 8. The two limiting blocks 8 are slidably connected to the limiting slots 7 on both sides. The rotating shaft 3 has a threaded connection section 9 at one end near the clamping disk 4. The control disk 10 is threadedly connected to the threaded connection section 9 on the rotating shaft 3. The control disk 10 and the clamping disk 4 are coaxially arranged. Three arc-shaped slots 11 are arranged in a ring array on the control disk 10. The bottom of each clamping block 6 is fixedly connected to a connecting rod 12 with a circular cross-section. The three connecting rods 12 are slidably connected to the three arc-shaped slots 11 respectively. The top of one of the clamping blocks 6 on each clamping disk 4 is fixedly connected to a fixing block 29. The side of the fixing block 29 away from the center of the clamping disk 4 is threadedly connected to a threaded button 30.

[0019] A row of wire roller placement racks 13 are fixedly connected at equal intervals on the side away from the clamping plate 4 on the processing table 1. The number and position of the wire roller placement racks 13 correspond to the clamping plate 4. A wire feeding roller 14 is rotatably connected to each wire roller placement rack 13. Multiple slide rods 15 are slidably connected through the middle of the processing table 1. A guide rod 16 is fixedly connected to the upper end of each slide rod 15. A lifting plate 20 is fixedly connected to the lower end of all guide rods 16. An installation groove 17 is opened at the bottom of the processing table 1. A forward and reverse motor 18 is installed and fixed on the top wall of the installation groove 17. A threaded shaft 19 is coaxially fixedly connected to the output shaft of the forward and reverse motor 18. The threaded shaft 19 and the lifting plate 20 are connected by a... The guide rod 16 is threaded and has a mounting bracket 26 fixedly connected to one end near the pay-off roller 14. The mounting bracket 26 is rotatably connected to a first guide wheel 27 via a pin. The end of each guide rod 16 near the clamping plate 4 is rotatably connected to two symmetrically distributed second guide wheels 28 via a pin. The surfaces of the two first guide wheels 27 and the two second guide wheels 28 are provided with concave surfaces. A circular hole is formed between the two first guide wheels 27. When the winding wire passes through the circular hole formed between the two first guide wheels 27, the bent winding wire is straightened by the compression of the first guide wheels 27 and the second guide wheels 28, which makes it easier to wind onto the iron core.

[0020] The lower end of each rotating shaft 3 passes through the processing table 1 and is coaxially fixedly connected to a sprocket 21. Multiple sprockets 21 are fitted together with a chain 22. The lower end of the threaded shaft 19 is coaxially fixedly connected to a drive wheel 23. The lower end of one of the rotating shafts 3 is coaxially fixedly connected to a driven wheel 24. The drive wheel 23 and the driven wheel 24 are fitted together with a transmission belt 25. The transmission ratio between the drive wheel 23 and the driven wheel 24 is 3:1. Each clamping block 6 has anti-slip texture on the side near the center of the clamping plate 4 to improve the stability of the clamping block 6 clamping the iron core.

[0021] When using the equipment of this invention, the iron core is first placed vertically on the clamping plate 4. Then, the control plate 10 is rotated while the clamping plate 4 is held down. The control plate 10 will cause the connecting rod 12 in the arc groove 11 to slide. The sliding of the connecting rod 12 will push the three clamping blocks 6 on the clamping plate 4 to move closer to the center at the same time. As the three clamping blocks 6 move closer to the iron core at the same time, the iron core is clamped and fixed in the center position of the clamping plate 4 by the pushing of the clamping blocks 6. The control plate 10 is connected to the threaded connection section 9 on the rotating shaft 3 by a thread. After the control plate 10 is rotated to the designated position, a thread self-locking will be formed to ensure the stability of the iron core clamping. After all the clamping plates 4 on the processing table 1 have clamped and fixed the iron core, one end of the winding wire on each wire feeding roller 14 passes through the first guide wheel 27 and the second guide wheel 28 in sequence and is placed between the fixing block 29 and the threaded button 30 of the corresponding clamping plate 4. Then, the threaded button 30 is turned to move closer to the fixing block 29 to clamp and fix the winding wire to the fixing block. On 29, after all the winding wires are threaded and fixed, the forward and reverse motor 18 can be turned on to drive the threaded shaft 19 to rotate. The drive wheel 23 at the lower end of the threaded shaft 19 will drive the rotating shaft 3 to rotate through the belt drive, and under the transmission of the chain drive, each rotating shaft 3 will rotate at the same speed and in the same direction. During the winding process of the iron core on the clamping plate 4, the lifting plate 20, which moves upward through the thread action, will push multiple sliding rods 15 to rise at a uniform speed, so that the guide rod 16 gradually moves the wire feeding of the iron core upward, so that the winding wire on the iron core is spirally wound. After the winding wire on the iron core is completed, the forward and reverse motor 18 is turned off first, and then the winding wire is cut. Then, when the control plate 10 is rotated in the reverse direction, the clamping block 6 slides away from the center, which makes it easy to remove the iron core. The entire iron core fixing and unloading operation is simple and quick, improving the winding efficiency. After all the iron cores are removed, the forward and reverse motor 18 is turned on and controlled to reverse to move the guide rod 16 to be flush with the fixing block 29, so that the next batch of iron cores can be wound.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
