Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic filters, and in particular relates to a magnetic filter with a lead-free plate medium layer filler. Background Art

[0002] The research and development of lead-free copper clad laminates is to meet the growing demand for environmental protection and the high-performance development trend of the electronics industry. At present, lead-free copper clad laminates have been widely used in various electronic devices, such as communications, computers, consumer electronics and other fields. With the high-performance development trend of electronic equipment, some terminal products have high overload currents. When using traditional lead-free materials, the voltage withstand test sometimes fails. Due to the requirement for improved heat resistance, ordinary lead-free materials often add a large amount of inorganic fillers to the glue formula. Inorganic fillers are used to reduce the thermal expansion coefficient of the material and improve the heat resistance of the board. However, the addition of inorganic materials will inevitably bring a certain amount of magnetic impurities into the composition, affecting the overall voltage withstand capability of the material.

[0003] During production, it is necessary to filter the magnetic impurities in the inorganic material glue, so a magnetic filter is needed. The traditional magnetic filter is installed on the glue pipeline, and the magnetic substance in the glue is adsorbed by the internal magnetic rod. However, the magnetic rod is in a fixed state, and the internal glue enters from one side and flows out from the other side. This causes the side of the magnetic rod facing the glue to adsorb a large amount of magnetic substance, while the adsorption amount on the back side becomes less, which affects the filtering effect and increases the maintenance frequency.

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a magnetic filter with a lead-free sheet material dielectric layer filling, which can realize the rotation of the magnetic rod. After a period of use, the magnetic rod can be rotated 180 degrees externally so that the back side faces forward, thereby reducing the maintenance frequency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A magnetic filter with a lead-free sheet material medium layer filler comprises a barrel body, the interior of the barrel body is hollow, inlet and outlet pipes are symmetrically arranged on both sides of the barrel body, the two inlet and outlet pipes are respectively connected to the interior of the barrel body, a cover plate is installed on the top of the barrel body, clamps are arranged on the outside of the barrel body and the cover plate, a boss is arranged at the bottom of the cover plate, the boss is placed inside the barrel body, a rotating shaft is evenly installed on the lower surface of the boss through bearings with the axis of the barrel body as the center, a magnetic rod is detachably installed on the end of the rotating shaft away from the boss, a gear one is arranged on the end of the rotating shaft away from the magnetic rod, the gear one is placed inside the boss, a gear two is installed at the center of the inner center of the boss through a bearing, and the gear two is respectively meshed with multiple gears one.

[0022] Please refer to Figure 1-Figure 4 As shown, a boss 8 is provided at the bottom of the cover plate 5 to increase the thickness of the cover plate 5, the boss 8 is placed inside the barrel body 1, and a rotating shaft 9 is evenly installed on the lower surface of the boss 8 through a bearing with the axis of the barrel body 1 as the center of the circle, and a magnetic rod 10 is detachably installed at one end of the rotating shaft 9 away from the boss 8. The magnetic rod 10 is installed and fixed by bolts to facilitate the disassembly of the magnetic rod 10 and the rotating shaft 9. At the same time, the magnetic rod 10 can rotate with the rotating shaft 9, and a gear 11 is provided at one end of the rotating shaft 9 away from the magnetic rod 10. The gear 11 is placed inside the boss 8, and a gear 2 12 is installed at the center of the boss 8 through a bearing. The gear 2 12 is respectively meshed with multiple gears 11, and the gear 2 12 is larger than the gear 11. Controlling the rotation of the gear 2 12 can drive multiple gears 11 to rotate together, thereby controlling the rotation of the magnetic rod 10.

[0023] Please refer to Figure 3 and Figure 4As shown, a control shaft 13 is provided at the center of the upper surface of the gear 2 12, and the top of the control shaft 13 is flush with the upper surface of the cover plate 5. The control shaft 13 and the gear 2 12 can rotate together. A slide rod 14 is slidably installed inside the control shaft 13. The top of the slide rod 14 passes through the upper surface of the control shaft 13. A knob 15 is provided on the top of the slide rod 14. The cross-section of the slide rod 14 is square. During the rotation of the slide rod 14, the control shaft 13 can be driven to rotate, and then the gear 2 12 can be driven to rotate.

[0024] Among them, a spring 16 is sleeved on the surface of the slide bar 14, the bottom of the spring 16 contacts the upper surface of the control shaft 13, and the top of the spring 16 contacts the lower surface of the knob 15. The elastic force of the spring 16 is used to place the slide bar 14 at the top of the stroke when not subject to external force, so that the limiting protrusion 18 at the bottom cooperates with the positioning groove 17 to remain fixed. Two positioning grooves 17 are provided on the inner upper surface of the boss 8 with the axis of the control shaft 13 as the center. The positions of the two positioning grooves 17 can ensure that the magnetic rod 10 is controlled to rotate exactly 180 degrees during rotation, so as to facilitate external operation.

At the same time, due to the existence of the spring 16, the knob 15 has an upward force, and then the limiting protrusion 18 at the bottom cooperates with the positioning groove 17 at the corresponding position to maintain the stability of the gear 2 12. At this time, the glue flows through the barrel body 1 through one side and passes through multiple magnetic rods 10 The magnetic material in the glue is adsorbed. After using it for a period of time, the knob 15 can be pressed downward to make the limiting protrusion 18 move downward and disengage from the positioning groove 17 at the corresponding position. At this time, rotating the knob 15 can drive the gear 2 12 to rotate. The downward pressure on the knob 15 is released to use the elastic force of the spring 16 to make the slide bar 14 and the limiting protrusion 18 have an upward force. The rotation of the gear 2 12 can drive multiple gears 11 to rotate, and then make multiple magnetic rods 10 rotate. When the magnetic rod 10 rotates 180 degrees, the limiting protrusion 18 cooperates with another positioning groove 17 to keep it fixed.

[0026] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
