Description

Technical Field

[0001] The invention relates to the technical field of inductor spraying, in particular to an inductor production spraying device and method. Background Art

[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, and it only blocks the change of current. If there is no current flowing through the inductor, it will try to block the current from flowing through it when the circuit is connected; if there is current flowing through the inductor, it will try to maintain the current when the circuit is disconnected. Inductors are also called chokes, reactors, and dynamic reactors. In order to protect the surface of the inductor workpiece from corrosion and enhance the surface finish, a protective layer is generally attached to the surface of the inductor workpiece to protect the inductor, which not only plays an insulating role, but also prevents the inductor from rusting.

[0003] Toroidal inductors are a common type of inductor. Toroidal inductors are in the shape of a ring. Specifically, copper wire is wound around the surface of the ring and extends to two pins. Before spraying the inductor, the pins of the inductor need to be wrapped with tape or a sheath to prevent the pins from being covered by paint during painting and affecting the conductivity of the inductor. After the inductor is sprayed, the tape or sheath on the inductor pins needs to be removed. For fully automated spraying, a separate inductor pin coating equipment is required, and the equipment cost is high. For some workshop-style production, workers are required to coat the inductor pins, which is time-consuming and inefficient. No matter which method is used, the coating process of the inductor pins cannot be avoided before spraying the inductor, which undoubtedly makes the current inductor spraying process cumbersome.

[0004] In view of this, in order to overcome the above technical problems, the present invention proposes an inductor production spraying device and method to solve the above technical problems. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art, the present invention proposes an inductor production spraying device and method. The present invention uses two mutually contacting conveyor belts to realize the spraying and clamping of the inductor while shielding the inductor pins, so that the inductor can be quickly sprayed while the pins are protected. Compared with the existing inductor spraying, the process of coating the inductor pins is saved, so that the inductor production efficiency is indirectly improved.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the inductor production spraying equipment described in the present invention comprises a spray box and a rotating spray head in the spray box; the rotating spray head can spray the coating toward the inductor; a feed port is provided at one end of the spray box, and a discharge port is provided at the other end; the spray box is connected to a track seat through the feed port and the discharge port; a driving roller, a steering roller and a driven roller are provided on the side of the track seat facing the rotating spray head; the driving roller and the driven roller are arranged near the end of the track seat; the steering roller is located between the driving roller and the driven roller and is arranged near the driven roller; the outer walls of the driving roller, the steering roller and the driven roller are connected to the conveyor belt through transmission; the two conveyor belts are connected to the track seat through transmission and are arranged in contact with each other; the distance between the two driven rollers on the track seat is greater than the distance between the two steering rollers; the ends of the two driving rollers on the track seat are meshed through gears, and one of the driving rollers is driven by a motor; the conveyor belt is made of elastic material.

[0007] Preferably, the side of the track seat on which the conveyor belt is arranged is arranged in a horizontal direction; and a V-shaped feeding gap is arranged near the position of the driven roller on the two conveyor belts on the track seat.

[0008] Preferably, a track groove is provided on the surface of the track seat; the end of the track groove passes through the end of the track seat; the active roller, the steering roller and the driven roller are rotatably connected to the bottom of the track groove; the sides of the conveyor belt that are away from each other are in contact with the wall of the track groove; and a filling strip is provided on the inner side of the conveyor belt.

[0009] Preferably, the steering roller includes a clamping portion away from the bottom of the corresponding track groove and a deformation portion close to the bottom of the corresponding track groove; the outer diameter of the deformation portion of the steering roller is arranged to change along the axial direction; the outer diameters of the deformation portions of the two steering rollers in the track groove are arranged to be adaptive; an avoidance groove is arranged on one side of two filling strips in the track groove close to each other; the avoidance groove is arranged close to the bottom of the track groove.

[0010] Preferably, the avoidance groove is arranged to penetrate toward the front side; and a transition surface is arranged at the rear end of the avoidance groove.

[0011] Preferably, the two avoidance grooves are each provided with a hemispherical block on one opposite side; the hemispherical block is located at the rear inner side of the spray box; and the hemispherical blocks in the two avoidance grooves are staggered with each other in the front-rear direction.

[0012] Preferably, the outer walls of the two conveyor belts in the track groove are provided with protrusions and recesses; the protrusions and recesses on the two conveyor belts in the track groove are arranged corresponding to each other.

[0013] An inductor production spraying method, which is applicable to the above-mentioned inductor production spraying equipment, and the steps of the method are as follows:

[0014] S1: The manufactured inductor is transported to the side of the spray box where the feed port is set, the motor and the rotating spray head are started, and the motor cooperates with the gear to drive the two conveyor belts to transmit in opposite directions; the two conveyor belts are transmitted on their respective driving rollers, steering rollers and the outer walls of the driven rollers, and the contact positions of the two conveyor belts on the track seat move backwards;

[0015] S2: Place the inductors toward the feeding gap in sequence. As the inductors approach the steering roller in the feeding gap, the conveyor belt drives the protrusions on the outer wall to bring the inductor pins between the two steering rollers. The clamping parts of the two steering rollers clamp the inductor pins close to the inductor body, and the deformation parts of the two steering rollers squeeze the inductor pins away from the inductor body.

[0016] S3: The deformed inductor pins follow the conveyor belt into the space between the two avoidance slots. The inductor follows the transmission of the conveyor belt into the spray box. The rotating nozzle in the spray box sprays the coating on the inductor. The conveyor belt shakes before removing the inductor from the spray box. The conveyor belt drives the inductor from the spray box into the drying box for drying.

[0017] S4: The inductor removed from the drying box enters the top of the receiving box, the pins of the inductor are removed from the avoidance slot and restored, the inductor is separated from the conveyor belt as the conveyor belt drives, and the inductor falls into the receiving box under the action of gravity, completing the inductor spraying process.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention uses two mutually contacting conveyor belts to realize spraying and clamping of the inductor while shielding the inductor pins, so that the inductor can be quickly sprayed while the pins are protected. Compared with the existing inductor spraying, the process of coating the inductor pins is saved, so that the inductor production efficiency is indirectly improved.

[0020] 2. The parts of the two filling strips in the present invention that are not provided with avoidance grooves ensure the restriction of the inductor pins, and the non-deformed parts of the inductor pins are clamped under the elastic deformation of the conveyor belt. Due to the deformation of the inductor pins away from the inductor body, the inductor is not easy to fall off the conveyor belt during transportation with the conveyor belt, thereby ensuring the stability of the inductor spraying.

[0021] 3. In the present invention, the hemispherical blocks in the two avoidance grooves are staggered in the front-to-back direction. Therefore, the hemispherical blocks will not cause the deformed pins to recover during the contact with the inductor pins through the conveyor belt. Instead, the inductor pins will be moved. In this way, the inductor will vibrate under the movement of the inductor pins. During the shaking of the inductor, the excess coating will be thrown into the spray box before leaving the spray box, thereby realizing the recycling of the coating and improving the uniformity of the coating on the surface of the inductor.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 9 As shown, the present invention includes the following embodiments:

[0035] Embodiment 1:

[0036] A spraying device for inductor production, comprising a spraying box 1 and a rotating spray head 11 in the spraying box 1; the rotating spray head 11 can spray a coating toward the inductor; a feed port 12 is provided at one end of the spraying box 1, and a discharge port 13 is provided at the other end; the spraying box 1 is connected to a track seat 2 through the feed port 12 and the discharge port 13; a driving roller 21, a steering roller 22 and a driven roller 23 are provided on the side of the track seat 2 facing the rotating spray head 11; the driving roller 21 and the driven roller 23 are provided near the end of the track seat 2; The steering roller 22 is located between the active roller 21 and the driven roller 23 and is arranged close to the driven roller 23; the outer walls of the active roller 21, the steering roller 22 and the driven roller 23 are transmission-connected to the conveyor belt 3; the two conveyor belts 3 are transmission-connected to the track seat 2 and are arranged in contact with each other; the distance between the two driven rollers 23 on the track seat 2 is greater than the distance between the two steering rollers 22; the ends of the two active rollers 21 on the track seat 2 are meshed through gears 24, and one of the active rollers 21 is driven by a motor 25; the conveyor belt 3 is made of elastic material.

[0037] In this embodiment, the side of the track base 2 on which the conveyor belt 3 is arranged faces the horizontal direction; the two conveyor belts 3 on the track base 2 are provided with a V-shaped feeding gap 26 near the driven roller 23 .

[0038] In this embodiment, a track groove 27 is provided on the surface of the track seat 2; the end of the track groove 27 passes through the end of the track seat 2; the active roller 21, the steering roller 22 and the driven roller 23 are rotatably connected to the bottom of the track groove 27; the side of the conveyor belt 3 that is away from each other is in contact with the wall of the track groove 27; and the inner side of the conveyor belt 3 is in contact with a filling strip 4.

[0039] During work, the staff transports the manufactured inductor to the side of the spray box 1 where the feed port 12 is set, starts the motor 25 and the rotating spray head 11, and the motor 25 drives one of the active rollers 21 on the track seat 2 to rotate. During the rotation of the active roller 21, the gear 24 meshed at the end is driven to rotate. The two active rollers 21 on the track seat 2 rotate under the meshing of the gears 24, and the two active rollers 21 rotate in opposite directions, so that the two conveyor belts 3 are transmitted on the outer walls of their respective active rollers 21, steering rollers 22 and driven rollers 23. The contact positions of the two conveyor belts 3 on the track seat 2 will pass through the spray box 1. After the motor 25 is started, the staff places the inductor in the feeding gap 26 in turn. The side is the front side of the spray box 1, and the side of the spray box 1 where the discharge port 13 is set is the rear side of the spray box 1. After the staff moves the two pins of the inductor to the feeding gap 26, the inductor is controlled to move backward, and the pins of the inductor will move toward the steering roller 22. The two pins of the inductor contact the outer walls of the two conveyor belts 3 after approaching the extreme position of the steering roller 22 in the feeding gap 26. The two conveyor belts 3 form friction after contacting with the pins, thereby bringing the pins into the contact position of the two conveyor belts 3 and being clamped by the contact surfaces of the two conveyor belts 3. The material of the conveyor belt 3 is elastic, such as rubber, so the conveyor belt 3 can use elastic force to clamp the pins. The staff releases the corresponding inductor after the pins are clamped, so that the inductor moves backward after being clamped by the two conveyor belts 3. The inductor is clamped in turn at the contact position of the two conveyor belts 3. The inductor will pass through the feed port 12 of the spray box 1 and enter the inner side of the spray box 1 as the conveyor belt 3 is driven. The rotating nozzle 11 will spray the coating on the surface of the inductor. Since the pins of the inductor are clamped at the contact position of the adjacent conveyor belts 3, the conveyor belt 3 will clamp the pins of the inductor tightly due to its own elasticity, so that it is difficult for the coating sprayed by the rotating nozzle 11 to enter the contact position of the two conveyor belts 3, so as to shield the pins of the inductor. During the spraying process, since the outer wall of the conveyor belt 3 is in contact with the track groove 27, and the inner wall of the conveyor belt 3 is in contact with the filling strip 4, the contact between the coating and the inner and outer walls of the conveyor belt 3 is reduced as much as possible during the process of the conveyor belt 3 passing through the inner side of the spray box 1, so as to ensure the conveying The belt 3 is clean, so as to prepare for the subsequent clamping of the inductor pins by the outer wall of the conveyor belt 3. In addition, since the side of the track seat 2 on which the conveyor belt 3 is set faces the horizontal direction, the coating is prevented from flowing into the contact position of the adjacent conveyor belt 3 and the pins of the inductor are prevented from falling off. When the track seat 2 is set with one side of the conveyor belt 3 facing downward, the insulating paint on the inductor will not drip onto the conveyor belt 3, but the inductor is easy to drive the pins to move out of the contact position of the adjacent conveyor belt 3 under the action of gravity. When the track seat 2 is set with one side of the conveyor belt 3 facing upward, although the gravity of the inductor is toward the track seat 2, making it difficult for the inductor pins to move out, the excess insulating paint on the inductor will drip onto the conveyor belt 3. Setting the side of the track seat 2 on which the conveyor belt 3 is set faces the horizontal direction can solve this problem well.The rotating nozzle 11 sprays the inductor more evenly during the rotation process. After the spraying is completed, the inductor continues to move backward with the conveyor belt 3, so that the sprayed inductor moves out of the discharge port 13 of the spray box 1 and enters the drying box (not shown in the figure). The drying box can dry the coating on the surface of the inductor. As the conveyor belt 3 continues to drive, the inductor moves out of the drying box and enters just above the receiving box (not shown in the figure). The inductor also moves away from the contact position of the adjacent conveyor belt 3 and falls off. In this way, the spraying process of the inductor is completed. The conveyor belt 3 continuously realizes the transmission of the inductor, and the rotating nozzle 11 continuously sprays, and the conveyor belt 3 can be replaced and cleaned;

[0040] The present invention transmits power through two mutually contacting conveyor belts 3, thereby achieving spray clamping of the inductor and shielding of the inductor pins at the same time, so that the inductor can be quickly sprayed while the pins are protected. Compared with the existing inductor spraying, the process of coating the inductor pins is saved, so that the inductor production efficiency is indirectly improved.

[0041] Embodiment 2:

[0042] The steering roller 22 includes a clamping portion 221 away from the bottom of the corresponding track groove 27 and a deformation portion 222 close to the bottom of the corresponding track groove 27; the outer diameter of the deformation portion 222 of the steering roller 22 is set to change along the axial direction; the outer diameters of the deformation portions 222 of the two steering rollers 22 in the track groove 27 are set to be adaptive; an avoidance groove 41 is set on one side of the two filling strips 4 close to each other in the track groove 27; the avoidance groove 41 is set close to the bottom of the track groove 27.

[0043] In this embodiment, the avoidance groove 41 is arranged to penetrate toward the front side; a transition surface 42 is arranged at the rear end of the avoidance groove 41 .

[0044] In this embodiment, the two avoidance grooves 41 are both provided with hemispherical blocks 43 on opposite sides; the hemispherical blocks 43 are located at the rear inner side of the spray box 1; the hemispherical blocks 43 in the two avoidance grooves 41 are staggered with each other in the front-rear direction.

[0045] In this embodiment, the outer walls of the two conveyor belts 3 in the track groove 27 are provided with protrusions 31 and recesses 32 ; the protrusions 31 and recesses 32 on the two conveyor belts 3 in the track groove 27 are provided correspondingly to each other.

[0046] During operation, the staff brings the pin of the inductor close to the steering roller 22 along the feeding gap 26, and the pin of the inductor contacts the conveyor belt 3. Then, the pin of the inductor is brought between the two steering rollers 22 under the action of friction. The clamping part 221 of the steering roller 22 is used to clamp the pin of the inductor. The distance between the two active rollers 21 in the track groove 27 is equal to the thickness of the two conveyor belts 3, and the distance between the two steering rollers 22 in the track groove 27 is equal to the thickness of the two conveyor belts 3. In this way, when the conveyor belt 3 is deformed, the pin of the inductor smoothly enters between the clamping parts 221 of the two steering rollers 22. At the same time, the pin of the inductor enters between the deformation parts 222 of the two steering rollers 22. In order to avoid the pin of the inductor from being stuck At a position where the feeding gap 26 is close to the steering roller 22, a protrusion 31 and a pit 32 are arranged on the outer wall of the conveyor belt 3. The protrusions 31 and the pits 32 on the two conveyor belts 3 are arranged corresponding to each other. In this way, on the one hand, the protrusion 31 is prevented from occupying the contact gap between the two conveyor belts 3, thereby ensuring the contact effect of the contact surfaces of the two conveyor belts 3. On the other hand, before the inductor pin enters the deformation parts 222 of the two steering rollers 22, the protrusion 31 can be used to move the inductor pin so that the inductor pin smoothly enters the deformation parts 222 of the two steering rollers 22. The larger diameter of the deformation part 222 of one steering roller 22 is radially aligned with the smaller diameter of the deformation part 222 of the other steering roller 22. In this way, when the two steering rollers 22 are deformed, the inductor pin can be moved. After the diameter of the deformed portion 222 changes in the axial direction, the deformed portions 222 of the two steering rollers 22 can squeeze the pins of the inductor, thereby squeezing the pins of the inductor into a corrugated shape. The corrugated pins enter between the two avoidance grooves 41 for avoidance along with the transmission of the conveyor belt 3. The portion of the conveyor belt 3 between the two avoidance grooves 41 has a smaller clamping force on the corrugated pins, thereby preventing the deformed pins from recovering. The portions of the two filling strips 4 without the avoidance grooves 41 ensure the restriction of the inductor pins, and clamp the non-deformed portions of the inductor pins in cooperation with the elastic deformation of the conveyor belt 3. Due to the deformation of the portion of the inductor pins away from the inductor body, the inductor is not easily deformed during the transportation process along the conveyor belt 3. The inductor falls off from the conveyor belt 3 to ensure the stability of the inductor spraying; the inductor will be sprayed by the rotating nozzle through the inner side of the spray box 1 under the transmission of the conveyor belt 3, and the inductor will pass through the area where the hemispherical block 43 is set in the avoidance groove 41 when it is at the rear position of the inner side of the spray box 1. The hemispherical blocks 43 in the two avoidance grooves 41 are staggered from each other in the front-to-back direction, so the hemispherical blocks 43 will not cause the deformed pins to recover during the contact process with the inductor pins across the conveyor belt 3, but will realize the movement of the inductor pins, so that the inductor will shake under the movement of the inductor pins, and the excess coating will be thrown into the spray box 1 before leaving the spray box 1 during the shaking process of the inductor, so as to realize the recycling of the coating and improve the uniformity of the coating on the surface of the inductor;After the excess coating on the inductor is shaken off, the inductor moves out along the discharge port 13 of the spray box 1 with the transmission of the conveyor belt 3. The inductor will continue to be driven by the conveyor belt 3 and move to the top of the receiving box after drying. The pins of the inductor move away from the avoidance groove 41 and enter the area where the two filling strips 4 are not provided with the avoidance groove 41 with the transmission of the conveyor belt 3. The transition surface 42 plays a role in the transition of the inductor pins. The two filling strips 4 squeeze the deformed pins. The pin material is copper, so that the inductor pins are restored at the position where the two filling strips 4 are not provided with the avoidance groove 41. After the deformed pins on the inductor are restored, the inductor is separated from the conveyor belt 3 and falls into the receiving box with the transmission of the conveyor belt 3. ;

[0050] S2: The inductors are placed toward the feeding gap 26 in sequence. As the pins of the inductors approach the steering roller 22 in the feeding gap 26, the conveyor belt 3 drives the protrusions 31 on the outer wall to bring the pins of the inductors between the two steering rollers 22. The clamping parts 221 of the two steering rollers 22 clamp the pins of the inductors close to the inductor body, and the deformation parts 222 of the two steering rollers 22 squeeze the pins of the inductors away from the inductor body.

[0051] S3: The deformed inductor pins enter between the two avoidance slots 41 along with the conveyor belt 3, and the inductor enters the spray box 1 along with the transmission of the conveyor belt 3. The rotating nozzle 11 in the spray box 1 sprays the coating on the inductor. The conveyor belt 3 shakes before removing the inductor from the spray box 1. The conveyor belt 3 drives the inductor from the spray box 1 into the drying box for drying.

[0052] S4: The inductor removed from the drying box enters the top of the receiving box, the pins of the inductor are removed from the avoidance groove 41 and restored, the inductor is separated from the conveyor belt 3 as the conveyor belt 3 is driven, and the inductor falls into the receiving box under the action of gravity, completing the inductor spraying process.

[0053] Embodiment 4:

[0054] An automatic loading device (not shown in the figure) is set on the front side of the spray box to automatically load the inductor. The drying box (not shown in the figure) is located at the rear of the spray box 1 and performs a drying process. The coating thrown out by the inductor in the spray box 1 will be gathered into the receiving box (not shown in the figure) on the bottom wall of the spray box 1 under the action of gravity. The receiving box has a built-in heating wire (not shown in the figure) to ensure the flow of the coating, and finally it flows out and is recycled after filtering and circulation treatment. The recycled part is not within the protection scope of the present invention and will not be elaborated here. The receiving box (not shown in the figure) is located at the rear of the drying box, and the upper port of the receiving box collects the inductor that falls off on the conveyor belt 3.

An inductor production spraying method, the method is applicable to the inductor production spraying equipment according to any one of claims 1 to 4, characterized in that: The steps of this method are as follows: S1: The manufactured inductor is transported to the side of the spray box (1) where the feed port (12) is set, and the motor (25) and the rotating spray head (11) are started. The motor (25) cooperates with the gear (24) to drive the two conveyor belts (3) to transmit in opposite directions; the two conveyor belts (3) are transmitted on the outer walls of their respective driving rollers (21), steering rollers (22) and driven rollers (23), and the contact positions of the two conveyor belts (3) on the track seat (2) move backwards; S2: The inductors are placed toward the feeding gap (26) in sequence. As the pins of the inductors approach the steering roller (22) in the feeding gap (26), the conveyor belt (3) drives the protrusions (31) on the outer wall to bring the pins of the inductors between the two steering rollers (22). The clamping parts (221) of the two steering rollers (22) clamp the pins of the inductors close to the inductor body, and the deformation parts (222) of the two steering rollers (22) squeeze the pins of the inductors away from the inductor body. S3: The deformed inductor pins follow the conveyor belt (3) into the space between the two avoidance grooves (41), and the inductor follows the transmission of the conveyor belt (3) into the spray box (1). The rotating nozzle (11) in the spray box (1) sprays the coating on the inductor. The conveyor belt (3) shakes before removing the inductor from the spray box (1), and the conveyor belt (3) drives the inductor from the spray box (1) into the drying box for drying. S4: The inductor removed from the drying box enters the top of the receiving box, the pins of the inductor are removed from the avoidance groove (41) and restored, the inductor is separated from the conveyor belt (3) as the conveyor belt (3) is driven, and the inductor falls into the receiving box under the action of gravity, completing the inductor spraying process.
