Description

Technical Field

[0001] This invention relates to the field of water washing equipment technology, specifically to an automatic water washing device for magnetic cores. Background Technology

[0002] A magnetic core is a sintered magnetic metal oxide composed of iron oxide mixtures (such as manganese-zinc ferrite, nickel-zinc ferrite, etc.). It is widely used in electronic components such as transformers, inductors, and filters. Its core function is to enhance and concentrate the magnetic field, thereby improving the performance of electronic components. Magnetic cores come in various types, such as manganese-zinc ferrite (high permeability, high magnetic flux density, low loss, suitable for high-frequency circuits) and nickel-zinc ferrite (high impedance, low permeability, often used for electromagnetic interference protection). They also come in a variety of geometric shapes, including cylindrical, I-shaped, cap-shaped, single-hole, double-hole, four-hole, U-shaped, can-shaped, E-shaped, EI-shaped, EC-shaped, RM-shaped, PQ-shaped, EP-shaped, etc., to adapt to different installation and heat dissipation requirements.

[0003] In traditional magnetic core cleaning processes, cleaning special-shaped magnetic cores is quite cumbersome and cannot achieve all-round cleaning, resulting in cleaning dead corners on the magnetic core surface, where residues cannot be completely removed, affecting the performance and service life of the magnetic core. Meanwhile, some ultrasonic cleaning equipment is expensive.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic water washing device for magnetic cores to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides an automatic magnetic core washing device, including a housing and a baffle. The housing has a storage channel extending along its length, and a cylindrical rotating groove is formed in the middle of the storage channel. The baffle is rotatably disposed within the rotating groove. A cleaning mechanism is provided within the rotating groove inside the housing. The cleaning mechanism includes:

[0007] A rack rod is vertically arranged and slidably connected to both ends of a baffle along its circumference. A nozzle is rotatably connected to the side wall of the rack rod away from the baffle. A drive gear is meshed on the bottom end of the rack rod near the axis of the rotating groove. A rotating cylinder is coaxially fixed inside the drive gear. The same rotating ring is meshed inside the multiple rotating cylinders. The rotating ring is coaxial with the rotating groove. A clamping mechanism is fixed at the top of the inner arc wall of the rotating ring. An annular groove is formed in the middle of the inner arc wall of the rotating ring. An internal gear ring is fixed in the groove. A drive gear is meshed on one side of the internal gear ring.

[0008] Furthermore, the inner arc wall of the rotating cylinder is provided with a plurality of spiral grooves arranged in a ring array about its axis, and a plurality of sliding columns arranged in a ring array about their own axis are fixed on the bottom wall of the rotating ring. The sliding columns are slidably adapted to the spiral grooves. A storage groove is provided on the bottom inner wall of the rotating groove on the box body. The shell is embedded in the storage groove. Vertical baffles are fixed on both opposite sides of its top outer edge. The baffles can close the connection between the storage channel and the rotating groove.

[0009] Furthermore, the clamping mechanism fixed to the top of the inner arc wall of the rotating ring includes a housing fixed to the inner arc wall of the rotating ring. A horizontally arranged top plate is fixed to the top of the inner arc wall of the housing. A sliding plate slides on the bottom of the top plate. A horizontally arranged rotating plate slides on the end of the sliding plate away from the top plate. A fixed shaft is fixed to the bottom of the rotating plate. A driven gear is fixed to the end of the fixed shaft away from the rotating plate. The fixed shaft passes through the bottom wall of the housing. A horizontally arranged driving gear two meshes on one side of the driven gear. The driving gear two avoids the driving gear one. The sliding plate adopts a waterproof structure. Vertically penetrating drainage holes are opened on the inner wall of the bottom of the housing, at the center of the top of the top plate, and at the center of the top of the rotating plate.

[0010] Furthermore, the top plate has multiple vertically penetrating sliding channels arranged in a circular array about its own axis. The length direction of the sliding channels is consistent with the radial direction of the top plate. Sliding columns are fixed on the side walls of the sliding plate near the top plate and the rotating plate, respectively. The sliding columns slide in the sliding channels. The rotating plate has multiple sliding grooves arranged in a circular array about the axis of the top plate on the side wall near the top plate. The sliding grooves are arc-shaped, with one end facing the axis of the rotating plate and the other end bent towards the outer edge of the rotating plate. The sliding columns on the side wall away from the top plate slide in the sliding grooves.

[0011] Furthermore, the upper surface of the top plate is provided with a mounting groove, a tray is installed in the mounting groove, a sliding sleeve is installed on the bottom surface of the tray, a through hole is opened in the mounting groove, the sliding sleeve passes through the through hole, and the lower end of the sliding sleeve is engaged with the upper end of the rotating plate.

[0012] Furthermore, a first disc tooth is installed at the end of the sliding sleeve, and a second disc tooth is installed on the end face of the rotating plate via a ratchet, with the first disc tooth and the second disc tooth cooperating with each other; at least one limiting groove is provided along the axial direction on the inner wall of the through hole, and at least one limiting strip is provided on the outer wall of the sliding sleeve, with the limiting strip slidably disposed in the limiting groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The cleaning mechanism enables multi-dimensional movement of the nozzle. The rack is vertically set and slidably connected to the baffle. Its bottom end meshes with the drive gear. The inner sides of multiple rotating cylinders are meshed with the same rotating ring coaxial with the rotating groove. This allows the nozzle to rotate and move up and down under the drive of the rotating ring, thereby achieving all-round cleaning of the magnetic core and effectively reducing cleaning dead angles.

[0015] 2. Through the clamping mechanism and the meshing transmission of the driven gear and the driving gear, the clamping mechanism can firmly hold the magnetic core and prevent it from being displaced by the water flow during the cleaning process. This ensures the stability and reliability of the cleaning process. Vertical drainage holes are provided at the bottom inner wall of the housing, the top center of the top plate, and the top center of the rotating plate to drain the sewage generated during the cleaning process in a timely manner and avoid secondary pollution of the magnetic core by water accumulation.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see the appendix Figure 1 To be continued Figure 5 The present invention provides an automatic water washing device for magnetic cores, comprising a housing 10 and a baffle 11. The housing 10 has a storage channel extending along its length, and a cylindrical rotating groove is formed in the middle of the storage channel. The baffle 11 is rotatably disposed within the rotating groove. A cleaning mechanism is provided within the rotating groove of the housing 10. The cleaning mechanism includes:

[0026] A rack 13 is vertically arranged and slidably connected to both ends of a baffle 11 along its circumference. A nozzle 12 is rotatably connected to the side wall of the rack 13 away from the baffle 11. A drive gear 14 is meshed on the bottom end of the rack 13 near the axis of the rotating groove. A rotating cylinder 15 is coaxially fixed inside the drive gear 14. The same rotating ring 16 is meshed inside the multiple rotating cylinders 15. The rotating ring 16 is coaxial with the rotating groove. A clamping mechanism is fixed at the top of the inner arc wall of the rotating ring 16. An annular groove is opened in the middle of the inner arc wall of the rotating ring 16. An internal gear ring is fixed in the groove. A drive gear 17 is meshed on one side of the internal gear ring.

[0027] The inner arc wall of the rotating cylinder 15 is provided with a plurality of spiral grooves arranged in a ring array about its axis, and the bottom wall of the rotating ring 16 is fixed with a plurality of sliding columns arranged in a ring array about its own axis, and the sliding columns are slidably adapted to the spiral grooves.

[0028] The clamping mechanism fixed to the top of the inner arc wall of the rotating ring 16 includes a housing 20 fixed to the inner arc wall of the rotating ring 16. A horizontally arranged top plate 21 is fixed to the top of the inner arc wall of the housing 20. A sliding plate 22 slides on the bottom of the top plate 21. A horizontally arranged rotating plate 23 slides on the end of the sliding plate 22 away from the top plate 21.

[0029] The top plate 21 has multiple vertically penetrating sliding channels arranged in a ring array about its own axis. The length direction of the sliding channels is consistent with the radial direction of the top plate 21. The sliding plate 22 has sliding columns fixed on the side walls near the top plate 21 and the rotating plate 23, respectively. The sliding columns slide in the sliding channels.

[0030] It should be noted that: in one possible embodiment, a vertically installed electric telescopic rod is installed on one side of the storage channel on the inner wall of the top of the housing 10, near the rotating groove. The telescopic end of the electric telescopic rod is fixed with an intercepting plate. The storage channel is used for the magnetic core to pass through, and a conveyor belt is fixed on the inner wall at the bottom of the storage channel for transporting the magnetic core.

[0031] The axial direction of the rotating cylinder 15 is parallel to the circumferential tangent of the rotating ring 16. A motor is fixed at the bottom of the drive gear 17. The drive gear 17 drives the internal gear ring to rotate, which in turn drives the rotating ring 16 to rotate. The rotation of the rotating ring 16 interacts with the spiral groove on the inner arc wall of the rotating cylinder 15 through the sliding column on its bottom wall, forcing the rotating cylinder 15 to rotate. The rotation of the rotating cylinder 15 drives the drive gear 14 to rotate. The meshing of the drive gear 14 with the rack 13 causes the rack 13 to move up and down. The rising, falling and rotating of the rack 13 drives the nozzle 12 to move in multiple dimensions, thereby cleaning the magnetic core in all directions.

[0032] Wastewater generated during the cleaning process is promptly discharged through the drainage holes at the bottom inner wall of the housing 20, the top center of the top plate 21, and the top center of the rotating plate 23, thus preventing water accumulation from causing secondary pollution to the magnetic core.

[0033] Please see the appendix Figure 1 To be continued Figure 5 The present invention provides a technical solution: a plurality of sliding grooves are provided on the side wall of the rotating plate 23 near the top plate 21 in a ring array about the axial direction of the top plate 21. The sliding grooves are arc-shaped, with one end facing the axis of the rotating plate 23 and the other end bent towards the outer edge of the rotating plate 23. The sliding column on the side wall away from the top plate 21 slides in the sliding groove.

[0034] The bottom of the rotating plate 23 is fixed with a fixed shaft, and a driven gear is fixed at the end of the fixed shaft away from the rotating plate 23. The fixed shaft is set through the bottom wall of the housing 20. A horizontally set driving gear 24 is meshed on one side of the driven gear. The driving gear 24 is set away from the driving gear 17.

[0035] The slide plate 22 adopts a waterproof structure, and vertically penetrating drainage holes are provided on the bottom inner wall of the shell 20, the top center of the top plate 21, and the top center of the rotating plate 23.

[0036] The inner wall of the bottom of the rotating groove on the box 10 is provided with a storage groove, and the shell 20 is embedded in the storage groove. Vertical baffles 11 are fixed on both sides of the outer edge of the top of the shell 20. The baffles 11 can close the connection between the storage channel and the rotating groove.

[0037] It should be noted that: the bottom of the second driving gear 24 is fixed with the second motor. The first motor and the second motor do not contact each other. The second driving gear 24 drives the driven gear to rotate, which in turn drives the rotating plate 23 to rotate through the fixed shaft. The arc-shaped sliding groove on the rotating plate 23 interacts with the sliding column on the sliding plate 22, causing the sliding plate 22 to move towards the axis along the sliding channel of the top plate 21, thereby clamping the magnetic core. For multiple magnetic cores, the magnetic cores can also be gathered together.

[0038] A robotic arm is installed on the inner top wall of the housing 10, near the rotating slot, at the location of the storage channel on the other side. This arm is used to remove the cleaned magnetic core. Further details will not be provided here.

[0039] Working principle:

[0040] The magnetic core is fed into the storage channel via a conveyor belt. The electric telescopic rod drives the intercepting plate to position the magnetic core. The active gear 24 drives the driven gear to rotate the rotating plate 23. The arc-shaped groove on the rotating plate 23 interacts with the sliding column of the sliding plate 22, pushing the sliding plate 22 to move towards the axis along the sliding channel of the top plate 21 and clamping the magnetic core.

[0041] The drive gear 17 drives the internal gear ring to rotate the rotating ring 16. The sliding column on the bottom wall of the rotating ring 16 cooperates with the spiral groove of the rotating cylinder 15, causing the rotating cylinder 15 to rotate and rise. The rotating cylinder 15 drives the drive gear 14 to rotate. The drive gear 14 meshes with the rack 13, causing the rack 13 to drive the nozzle 12 to move up, down and rotate, realizing multi-dimensional spray cleaning. The cleaning wastewater is discharged through the drain holes of the housing 20, the top plate 21 and the rotating plate 23. After cleaning, the robotic arm removes the magnetic core, and the baffle 11 closes the channel to prevent water splashing, completing the fully automated cleaning process.

[0042] Preferred, such as Figure 6 As shown, the upper surface of the top plate 21 is provided with a mounting groove 25, and a tray 26 is installed in the mounting groove 25. The tray 26 is made of stainless steel or engineering plastic. A sliding sleeve 27 is installed on the bottom surface of the tray 26. A through hole is opened in the mounting groove 25, and the sliding sleeve 27 passes through the through hole. The lower end of the sliding sleeve 27 is matched with the upper end of the rotating plate 23. The top of the rotating plate 23 is provided with a groove or protrusion structure that matches the sliding sleeve 27, so as to ensure that the sliding sleeve 27 can drive the tray 26 to move synchronously when sliding axially.

[0043] When the driving gear 24 drives the driven gear to rotate, the rotating plate 23 rotates synchronously, causing the tray 26 to rotate. This allows the magnetic core to rotate with the rotating plate 23 before being clamped, enabling the nozzle 12 to thoroughly clean the sides of the magnetic core from multiple angles. This prevents the clamped area of ​​the magnetic core from being left uncleaned and improves the cleaning coverage.

[0044] Furthermore, a first disc tooth 28 is installed at the end of the sliding sleeve 27, and a second disc tooth 29 is installed on the end face of the rotating plate 23 via a ratchet, so that the second disc tooth 29 can rotate together with the rotating plate 23 in one direction. In this embodiment, this is the rotation direction of the rotating plate 23 during the magnetic core clamping process. The second disc tooth 29 does not rotate together with the rotating plate 23 during the magnetic core release process. The first disc tooth 28 and the second disc tooth 29 cooperate with each other. Both the first disc tooth 28 and the second disc tooth 29 are made of stainless steel. The inner wall of the through hole is provided with at least one limiting groove 30 along the axial direction, and the outer wall of the sliding sleeve 27 is provided with at least one limiting strip 31. The limiting strip 31 is slidably disposed in the limiting groove 30.

[0045] When the rotating plate 23 rotates, due to the limiting strip 31 being set in the limiting groove 30, the first disc tooth 28 and the second disc tooth 29 will slip, causing the limiting strip 31 to move up and down in the limiting groove 30, and the tray 26 to move up and down synchronously. After the magnetic core is clamped, the rotating plate 23 stops rotating. Since the second disc tooth 29 is mounted on the rotating plate 23 through a ratchet, the weight of the tray 26 and the sliding sleeve 27 presses downward, causing the first disc tooth 28 and the second disc tooth 29 to rotate relative to each other to the meshing position. Then the tray 26 moves downward by the tooth height distance of the first disc tooth 28, so that the tray 26 and the magnetic core have a gap, and the nozzle 12 can rinse the bottom of the magnetic core, further improving the cleaning range and the cleaning effect.
