Description
Technical Field
[0001] This invention provides a coating equipment specifically for inductor production, specifically relating to the field of inductor manufacturing technology. Background Technology
[0002] Inductor manufacturing requires a coating process, which involves wrapping a layer of adhesive material around the inductor body (such as the coil or magnetic core) to provide protection, insulation, and fixation. Coating equipment is specifically designed for this process.
[0003] In the prior art, the coating device of CN118919293B uses a pressing and compacting component to tightly adhere the two ends of the tape to the inductor (only the two ends of the tape are adhered); the coating device of CN222421647U is equipped with a coating mechanism and a clamping component, which can coat two inductors at one time to improve efficiency.
[0004] However, existing inductor coating equipment still has shortcomings in actual coating processes: The existing coating devices described above suffer from several drawbacks during the actual coating process. Poor surface condition of the inductor coil, mismatched tape characteristics, improper coating process parameters, insufficient equipment precision, or environmental interference can prevent the tape from making tight contact with the coil surface. This results in bulging and poor adhesion in localized areas of the inductor coil, severely impacting the coating quality and the inductor's practical application. Furthermore, the coating efficiency of existing devices is low. During the coating process, manual loading of the inductor to be coated onto the machine is still required, leading to inefficient coating operations and making them unsuitable for continuous coating needs.
[0005] Therefore, this invention proposes a coating equipment specifically for inductors to improve upon the shortcomings of existing technologies. Summary of the Invention

A support frame is fixedly installed on the top surface of the base near the main body of the coating machine, and a gantry frame is fixedly installed on the side of the support frame near the coating assembly. An automatic supply mechanism, integrated on the base and support frame, is used to automatically feed the inductor to the coating assembly for coating. The follow-up smoothing mechanism is located on the side of the support frame near the rubber-coated component; The follow-up smoothing mechanism includes two miniature electric slide rails that are fixedly installed on the support frame and the gantry frame respectively. Both miniature electric slide rails are located on the side close to the rubber-coated component, and each miniature electric slide rail is slidably provided with a slide seat. An electric telescopic rod is fixedly installed on the side of the slide seats that are close to each other. A smoothing rod is detachably connected to the end of the piston rod of the electric telescopic rod. When the two smoothing rods approach each other to their final position, they adapt to the outer contour of the inductor coil and fit against the outer surface of the inductor coil.
[0008] Preferably, the overcoating assembly includes a switching turntable rotatably connected to the side of the overcoating machine body near the support frame. Two drive motors are embedded in the side of the switching turntable near the support frame and are arranged symmetrically about the axis of the switching turntable. The output shafts of the two drive motors are detachably connected to a bearing shaft for loading inductors. A winding wheel is rotatably mounted on the side of the overcoating machine body near the support frame. A tape for overcoating inductor coils is wound on the outer circumference of the winding wheel. A transition roller is rotatably connected to the side of the overcoating machine body next to the winding wheel. One end of the tape passes over the outer circumference of the bottom of the transition roller. A cutter is also provided on the side of the overcoating machine body near the support frame. The cutter moves horizontally through a telescopic device to cut the tape.
[0009] Preferably, the switching turntable is driven to rotate by an external servo motor. The control signal input terminal of the servo motor is connected to the main controller on the body of the coating machine. The main controller is configured to control the switching turntable to rotate 180 degrees each time, so that the two bearing shafts alternately enter the coating station.
[0010] Preferably, the position of the follow-up smoothing mechanism corresponds to the bearing shaft located below.
[0011] Preferably, the telescopic device is an electrically controlled telescopic cylinder, which is installed on the body of the coating machine, and the piston rod end of the electrically controlled telescopic cylinder is connected to the blade by bolts.
[0012] Preferably, the two smoothing rods are U-shaped or semi-circular.
[0013] Preferably, the detachable connection between the smoothing rod and the electric telescopic rod piston rod is a quick-change joint structure, and the end of the electric telescopic rod piston rod is provided with an external thread head, which is threadedly connected to the internal thread hole on the smoothing rod through the external thread head.
[0014] As a preferred embodiment, the automatic feeding mechanism includes a vibrating feeder fixedly installed on one side of the top surface of the base. The vibrating feeder has a feeding channel on the side near the body of the coating machine. A conveyor belt is installed on the support frame. One end of the conveyor belt is the docking end, and the other end is the feeding end. The end of the feeding channel away from the vibrating feeder is horizontally connected to the docking end of the conveyor belt to realize the automatic feeding of the inductor. A measuring component is fixedly installed on the top of the gantry frame. A pushing cylinder is fixedly installed on the side of the gantry frame away from the bearing shaft. A suction cup is fixedly installed at the piston rod end of the pushing cylinder. A small vacuum pump is fixedly installed on the gantry frame.

[0015] Preferably, the positioning component is configured as a laser positioning sensor, with the laser emission direction at its bottom perpendicular to the horizontal axis of the suction cup.
[0016] Compared with the known prior art, the technical solution provided by this invention has the following beneficial effects: This specialized inductor coating equipment, through its design that adapts the smoothing rod to the outer contour of the coil, combined with the real-time telescopic adjustment of the electric telescopic rod and the cooperation of the miniature electric slide rail and slide block, can eliminate wrinkles and air bubbles caused by tension fluctuations during tape winding. This ensures that the tape adheres tightly to the inductor coil area, improves the tightness of the tape adhesion, reduces the risk of later detachment or the risk of dust entering due to poor adhesion, and significantly improves the coating quality of inductors. The automatic feeding mechanism achieves full automation of inductor feeding and loading through the coordination of vibrating feeder, laser positioning and suction cups, replacing manual feeding, which not only reduces labor costs, but also reduces positioning deviation caused by manual operation, and further improves the inductor coating efficiency. Meanwhile, the detachable structure of the bearing shaft, smoothing rod and winding wheel allows for quick replacement to adapt to inductor coils of different sizes and shapes without replacing the entire machine, thus reducing equipment adaptation costs. The main controller enables coordinated control of the switching turntable, drive motor, and follow-up smoothing mechanism, achieving seamless automatic connection of coating, switching, and smoothing actions, reducing manual intervention and improving the stability of single coating. Real-time detection by the positioning component and closed-loop control by the main controller ensure precise alignment between the inductor shaft and the bearing shaft, preventing skewing of the coating due to loading offset and improving the consistency of coil coating. In summary, this inductor production coating equipment can achieve automatic feeding, coating component connection, and follow-up smoothing mechanism. With the dual-station design of the switching turntable, it can realize parallel operation of "material feeding-coating-removal-air bubble and wrinkle removal-feeding", reduce equipment idle time and improve the coating efficiency of inductors per unit time.

[0019] The present invention will be further described below with reference to embodiments.
[0020] Example 1: like Figures 1 to 6 As shown, a special equipment for producing inductors with a coating process includes a base 1, a coating machine body 11 fixedly mounted on the base 1, a main controller 12 mounted on the coating machine body 11, and a coating assembly mounted on the coating machine body 11. The coating assembly is used to coat the coil of the inductor. The coating assembly includes a switching turntable 13 rotatably connected to the side of the coating machine body 11 near the support frame 23. The switching turntable 13 is driven to rotate by an external servo motor. The control signal input terminal of the servo motor is connected to the main controller 12 on the coating machine body 11. The main controller 12 is configured to control the switching turntable 13 to rotate 180 degrees each time, so that the two bearing shafts 15 alternately enter the coating station. Two drive motors 14 are embedded in the side of the switching turntable 13 near the support frame 23. The two drive motors 14 are arranged symmetrically with reference to the axis of the switching turntable 13. The output shaft ends of the two drive motors 14 are detachably connected to the bearing shafts 15 for loading inductors. Specifically, the bearing shafts 15 and the output shafts of the drive motors 14 are connected by a clamp structure or a threaded connection structure, so that the operator can easily replace the appropriate bearing shafts 15 for different models and sizes of inductors. A winding wheel 16 is rotatably arranged on the side of the coating machine body 11 near the support frame 23. The corresponding winding wheel 16 can also be disassembled and replaced. A tape for wrapping an inductor coil is wound around the outer circumference of the winding pulley 16. A transition roller 17 is rotatably connected to the main body 11 of the coating machine next to the winding pulley 16. One end of the tape passes over the outer circumference of the bottom of the transition roller 17. A cutter 18 is also provided on the side of the main body 11 of the coating machine near the support frame 23. The cutter 18 moves horizontally through a telescopic device to cut the tape. The telescopic device is an electrically controlled telescopic cylinder, which is installed on the main body 11 of the coating machine. The piston rod end of the electrically controlled telescopic cylinder is connected to the cutter 18 by bolts. The cutter 18 is driven to move horizontally stably by the electrically controlled telescopic cylinder to automatically switch the tape. At the same time, the cutter 18 can be disassembled and separated from the piston rod for timely replacement of worn cutter 18.
[0021] A support frame 23 is fixedly installed on the top surface of the base 1 near the body 11 of the coating machine, and a gantry frame 25 is fixedly installed on the side of the support frame 23 near the coating assembly. Furthermore, a follow-up smoothing mechanism is provided on the side of the support frame 23 near the rubber-coated assembly. The position of the follow-up smoothing mechanism corresponds to the bearing shaft 15 located below. It is worth noting that when the two bearing shafts 15 rotate 180 degrees, the follow-up smoothing mechanism will not hinder the normal rotation of the two bearing shafts 15.
[0022] The follow-up smoothing mechanism includes two miniature electric slide rails 31, respectively fixedly mounted on the support frame 23 and the portal frame 25. Both miniature electric slide rails 31 are located near the rubber-coated assembly, and each miniature electric slide rail 31 has a sliding base 32. An electric telescopic rod 33 is fixedly mounted on the side of the sliding bases 32 that are close to each other. A smoothing rod 34 is detachably connected to the end of the piston rod of the electric telescopic rod 33. The detachable connection between the smoothing rod 34 and the piston rod of the electric telescopic rod 33 is a quick-connect coupling structure. The end of the piston rod of the electric telescopic rod 33 has an external thread head, which is threaded into the internal thread hole on the smoothing rod 34, thus enabling detachment. This facilitates the removal of the two smoothing rods 34 and replacement with smoothing rods 34 that are adapted to the shape of the inductor coil, improving the applicability of the follow-up smoothing mechanism. When the two smoothing rods 34 approach each other to their final position, they adapt to the outer contour of the inductor coil and fit against the outer surface of the inductor coil. As an implementation, the two smoothing rods 34 are U-shaped or semi-circular. The shape of the two smoothing rods 34 should be adapted to the outer contour shape of the inductor coil part, but is not limited to the U-shaped or semi-circular shape in this embodiment. At the same time, the stroke of the two slides 32 and the two electric telescopic rods 33 can be programmed and controlled by the body 11 of the overmolding machine to be suitable for inductors of different sizes, thereby improving its practicality and applicability.
[0023] When using: such as Figure 1 As shown, the worker first installs an inductor to be coated with adhesive onto the upper support shaft 15 (Note: the lower support shaft 15 is installed by an automatic supply mechanism, the specific working principle of which will be explained in detail in Embodiment 2). Then, one end of the adhesive tape is guided by the transition roller 17 and attached to the surface of the inductor coil. Subsequently, the drive motor 14 drives the upper support shaft 15 and the inductor to rotate synchronously, causing the adhesive tape to rotate and wrap around the outside of the coil.
[0024] After the rotary coating is completed, the switching turntable 13 is rotated 180 degrees by an external servo motor, switching the coated inductor to the lower position. During this process, the cutter 18 is moved horizontally by an electrically controlled telescopic cylinder, automatically cutting the tape. Then, the two electric telescopic rods 33 are activated, causing the two smoothing rods 34 to move towards each other and contact the tape at the inductor coil. Then, the miniature electric slide rail 31 is activated, causing the slide block 32 to move horizontally back and forth, so that the two smoothing rods 34 move synchronously with the tape.
[0025] Example 2: like Figure 1 , Figure 2 , Figures 7 to 10As shown, the above-mentioned inductor production coating equipment also includes an automatic feeding mechanism, which includes a vibrating feeder 21 fixedly installed on one side of the top surface of the base 1. The vibrating feeder 21 has a feeding channel 22 on the side near the coating machine body 11. A conveyor belt 24 is installed on the support frame 23. One end of the conveyor belt 24 is the docking end and the other end is the feeding end. The end of the feeding channel 22 away from the vibrating feeder 21 is horizontally connected to the docking end of the conveyor belt 24 to realize the automatic feeding of the inductor. A measuring component 26 is fixedly installed on the top of the gantry frame 25. A pushing cylinder 27 is fixedly installed on the side of the gantry frame 25 away from the bearing shaft 15. A suction cup 28 is fixedly installed at the piston rod end of the pushing cylinder 27. A small vacuum pump 29 is fixedly installed on the gantry frame 25. The suction end of the small vacuum pump 29 is connected to the suction cup 28 through a hose. The horizontal axes of the push cylinder 27 and the suction cup 28 correspond to and are parallel to the horizontal axis of the positioning component 26. The positioning component 26 emits a laser from its bottom to detect the position of the inductor's axis and the position of the suction cup 28's axis in real time. The positioning component 26 is configured as a laser positioning sensor, and the laser emission direction at its bottom is perpendicular to the horizontal axis of the suction cup 28. Specifically, when the laser positioning sensor detects that the inductor's axis corresponds to the suction cup 28's axis, the laser positioning sensor sends the electrical signal to the main controller 12. The main controller 12 stops the conveyor belt 24, causing the inductor to stop at that position. At this time, the suction surface of the suction cup 28 is in contact with one end of the inductor. The small vacuum pump 29 is started to generate negative pressure on the suction surface of the suction cup 28 to stably hold the inductor. After the adsorption is stable, the push cylinder 27 is started so that its piston rod drives the inductor to move horizontally towards the bearing shaft 15 located below, thus automatically loading the inductor and the bearing shaft 15.
[0026] In use: The staff can put the inductors to be coated into the vibrating feeder 21 in advance. The vibrating feeder 21 arranges the inductors in an orderly manner and transports them to the conveyor belt 24 through the delivery channel 22. The conveyor belt 24 moves the inductors to the delivery end.
[0027] In this process, when the positioning component 26 emits a laser to detect the position of the inductor's axis, and it aligns with the axis of the suction cup 28, the main controller 12 stops the conveyor belt 24, the push cylinder 27 drives the suction cup 28 to move forward and adhere to the end of the inductor, and the small vacuum pump 29 starts to generate negative pressure on the suction cup 28 to attract the inductor; then the push cylinder 27 moves the inductor to the lower support shaft 15 and completes the loading. After the suction cup 28 releases the negative pressure, the switching turntable 13 automatically rotates 180 degrees to switch the inductor loaded below to the upper position, and then the steps of the above embodiment one are repeated to perform the encapsulation.
[0028] At this point, the inductor end that has been coated and moved to the lower position is attached to the suction cup 28. The small vacuum pump 29 is started again to make the suction cup 28 stably hold the coated inductor. Then, the piston rod of the cylinder 27 is pushed back to place the coated inductor back onto the conveyor belt 24 and release the negative pressure of the suction cup 28. Then, the main controller 12 starts the conveyor belt 24 again to send the coated inductor away from the coating station and send the inductor to be coated into the coating station. By repeating the steps, the continuous coating operation of the inductor can be realized.
[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
