Description

Technical Field

[0001] This utility model is an impregnation machine for preparing inductor coils, belonging to the field of inductor coils. Background Technology

[0002] As is well known, an impregnation machine is a device suitable for impregnating high-frequency and low-frequency transformers, inductors, motors, inductors, rectifiers, hardware castings, and C-type iron cores with varnish, and it is widely used in the field.

[0003] Existing inductor coils require an impregnation machine after subsequent processing and molding to coat their outer surface with a protective oil layer. However, existing impregnation machines suffer from poor impregnation efficiency. For example, a patented impregnation machine for inductor coil preparation (CN202023247230.8) introduces oil from a storage tank into an impregnation tank 1. When the oil level reaches a certain height, the suction valve, exhaust valve, and vacuum pump are closed, and the motor is turned on. The motor rotation drives the circular plate and fixed rod to rotate. Through the rotational connection between the fixed rod and the impregnation frame, the impregnation frame rotates. Multiple impregnation frames intermittently impregnate the coils with oil, resulting in good impregnation. After impregnation, the motor is turned off, and the exhaust valve and connecting valve are opened. Through the connecting pipe, under the gravity of the oil in the storage tank, the gas introduced from the gas storage tank is introduced into the impregnation tank, causing the oil level to drop. All impregnation frames stop impregnating, and excess oil drips off after settling. After settling, the oil-impregnated coils can be removed.

[0004] According to the aforementioned patent, the specific process involves rotating the impregnation frame to intermittently impregnate the coil with oil. After the process is completed, the oil is lowered and removed, and the coil is left to stand still. This standing still method removes excess oil from the coil. However, there is a gap in the process. During this gap, subsequent coil impregnation cannot be performed, which affects the efficiency of subsequent coil impregnation. Therefore, this application proposes a novel impregnation machine for preparing inductor coils. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an impregnation machine for preparing inductor coils.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] An impregnation machine for preparing inductor coils includes an impregnation chamber with an open top. An external frame is fixedly mounted on the outer wall of the impregnation chamber. A U-shaped frame is fixedly mounted on the top of the external frame. Two height adjustment components are mounted on the U-shaped frame. Each height adjustment component is equipped with two connecting rods. Each height adjustment component is connected to an impregnation component through the connecting rods. The impregnation component includes a top plate connected to the connecting rods. U-shaped sliding rods are fixedly mounted on both sides of the bottom end of the top plate. Two sliders slide on each U-shaped sliding rod. A secondary connecting rod is fixedly mounted on the bottom end of each slider. An impregnation basket is fixedly mounted on the bottom end of the secondary connecting rod. A secondary impregnation basket is fixedly mounted on the bottom end of the impregnation basket through several support rods.

[0008] Furthermore, the height adjustment component includes a drive motor fixed at the top of the U-shaped frame, with a lead screw connected to the output end of the drive motor, and a lifting platform threaded onto the lead screw.

[0009] Furthermore, the top of the connecting rod is fixed to the bottom of the lifting platform, and the bottom of the lead screw is fitted with a bearing fixed to the top of the external frame.

[0010] Furthermore, a mounting cavity is provided inside the top plate. An I-shaped drive disc is rotatably connected to the bottom of the mounting cavity via a secondary bearing. There are two secondary bearings and two drive discs. A transmission belt connects the two drive discs. A secondary drive motor that drives one of the drive discs is provided inside the mounting cavity.

[0011] Furthermore, each transmission belt has a rotating rod extending through the top plate at its bottom end, and a second drive disc is located at the bottom end of the rotating rod. The rotating rod is eccentrically positioned on the second drive disc, and a contact plate is fixedly mounted on two auxiliary connecting rods near the second drive disc.

[0012] Furthermore, an L-shaped plate is fixedly installed on the top plate, and a mounting plate is fixedly installed on two auxiliary connecting rods near the L-shaped plate. Two buffer reset components are connected between the mounting plate and the L-shaped plate.

[0013] Furthermore, the buffer reset assembly is a buffer reset spring, with mounting plates fixed at both ends of the buffer reset spring. The mounting plates are fixed to the mounting plate and the L-shaped plate with screws.

[0014] Furthermore, the impregnation tank is equipped with an oil drain pipe with a manual control valve, and ball bearings are rolled and embedded on the inner wall of each side of the slider.

[0015] The beneficial effects of this utility model are:

[0016] The coils to be impregnated with oil are placed in the impregnation basket and the secondary impregnation basket. The impregnation oil is poured into the impregnation tank. Then, one of the height adjustment components is controlled to lower the impregnation basket and the secondary impregnation basket into the impregnation tank, thereby completing the oil impregnation process for the coils in the impregnation basket and the secondary impregnation basket.

[0017] After oil impregnation is completed, the impregnation basket and the auxiliary impregnation basket are raised, and another height adjustment component is controlled to lower the other set of impregnation baskets and the auxiliary impregnation basket, so as to complete the subsequent internal coil processing of the other impregnation baskets and the auxiliary impregnation basket.

[0018] This invention features a lifting and lowering mechanism that ensures the oil-soaking process is completed simultaneously while the already soaked coil is suspended, allowing excess oil to drip off. Finally, the soaked coil can be removed, thus enabling uninterrupted oil-soaking and improving efficiency. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-2 This utility model provides a technical solution: an impregnation machine for preparing inductor coils, including an impregnation box 1 with an open top, an external frame 2 fixedly mounted on the outer wall of the impregnation box 1, a U-shaped frame 3 fixedly mounted on the top of the external frame 2, two height adjustment components mounted on the U-shaped frame 3, each height adjustment component being provided with two connecting rods 4, each height adjustment component being connected to an impregnation component via the connecting rods 4, the impregnation component including a top plate 5 connected to the connecting rods 4, U-shaped sliding rods 6 fixedly mounted on both sides of the bottom end of the top plate 5, two sliding blocks 7 sliding on each U-shaped sliding rod 6, a secondary connecting rod 8 fixedly mounted on the bottom end of the sliding block 7, an impregnation basket 9 fixedly mounted on the bottom end of the secondary connecting rod 8, and a secondary impregnation basket 10 fixedly mounted on the bottom end of the impregnation basket 9 via several support rods.

[0028] See Figure 1 The height adjustment component includes a drive motor 11 fixed at the top of the U-shaped frame 3. The output end of the drive motor 11 is connected to a lead screw 12. A lifting platform 13 is threaded onto the lead screw 12. The top end of the connecting rod 4 is fixed to the bottom end of the lifting platform 13. A bearing fixed to the top of the outer frame 2 is fitted onto the bottom of the lead screw 12. The drive motor 11 drives the lead screw 12 to rotate, thereby driving the lifting platform 13 to complete vertical lifting on the lead screw. Finally, the two sets of impregnation baskets 9 and auxiliary impregnation baskets 10 are raised and lowered, ensuring that the oil impregnation work is completed on one side and the coil that has completed the oil impregnation work is suspended on the other side, ensuring that excess oil on the coil drips off.

[0029] See Figure 1-3The top plate 5 has a cavity 15 inside. Two I-shaped drive discs 16 are rotatably connected to the bottom of the cavity 15 via a secondary bearing. A transmission belt 17 connects the two drive discs 16. A secondary drive motor for driving one of the drive discs 16 is located inside the cavity 15. A rotating rod 18 protrudes from the bottom of each transmission belt 17 through the top plate 5. A second drive disc 19 is located at the bottom of each rotating rod 18. The rotating rod 18 is eccentrically positioned on the second drive disc 19. A contact plate 20 is fixedly mounted on two secondary connecting rods 8 near the second drive disc 19. An L-shaped plate 21 is fixedly mounted on the top plate 5. A mounting plate 22 is fixedly mounted on two secondary connecting rods 8 near the L-shaped plate 21. Two buffer reset assemblies, each a buffer reset spring 23, are connected between the mounting plate 22 and the L-shaped plate 21. Both ends of the buffer reset spring 23 are fixedly mounted... There is a mounting plate 24, which is fixed to the mounting plate 22 and the L-shaped plate 21 with screws. It is used to suspend the coil that has completed the oil impregnation process, so that the excess oil on the coil can drip off. During the suspension process, the auxiliary drive motor can be driven to drive the rotation of the drive plate 16. The two drive plates 16 are connected by a transmission belt 17, so they drive the two rotating rods 18 and the drive plate 19 to rotate. The rotating rods 18 and the drive plate 19 are eccentrically set, so the rotation of the drive plate 19 continuously collides with the contact plate 20, thus driving the impregnation basket 9 and the auxiliary impregnation basket 10 to move. The slider 7 connected to them slides on the U-shaped slide rod 6, which plays a supporting role. With the reset of the buffer spring, the impregnation basket 9 and the auxiliary impregnation basket 10 move left and right, so as to effectively slide the coil inside the impregnation basket 9 and the auxiliary impregnation basket 10, and accelerate the effect of ensuring that the excess oil on the coil drips off.

[0030] See Figure 1-4 The impregnation tank 1 is also equipped with an oil drain pipe with a manual control valve. Each side of the inner wall of the slider 7 is inlaid with rolling balls 14. Three-quarters of the volume of the rolling balls 14 is inlaid in the inner wall of the slider 7. The rolling balls 14 roll on the U-shaped slide bar 6 to ensure the smoothness of the movement and to ensure that the friction force is greatly reduced during the movement, further ensuring the smoothness of the movement.

[0031] In practice, the coils to be soaked in oil are placed in the soaking basket 9 and the secondary soaking basket 10. The soaking oil is poured into the soaking tank 1. Then, one of the height adjustment components is controlled to lower the soaking basket 9 and the secondary soaking basket 10 into the soaking tank 1, thus completing the oil soaking process for the coils in the soaking basket 9 and the secondary soaking basket 10. After the oil soaking is completed, the soaking basket 9 and the secondary soaking basket 10 are raised. Then, another height adjustment component is controlled to lower another set of soaking baskets 9 and the secondary soaking basket 10 to complete the subsequent processing of the coils in the other soaking baskets 9 and the secondary soaking basket 10. This utility model ensures that the oil soaking process is completed while the soaked coils are suspended, ensuring that excess oil drips off the coils. Finally, the soaked coils can be taken out.

[0032] The impregnation tank 1 is an oil-containing space with internal depth. When the impregnation basket 9 and the auxiliary impregnation basket 10, which have completed the oil impregnation work, are raised, the height is limited. At this time, the impregnation basket 9 and the auxiliary impregnation basket 10, which have completed the oil impregnation work, are still suspended inside the impregnation tank 1 to ensure that the oil on the coil is not splashed to the outside of the impregnation tank 1 when shaking and slinging the oil later. After the oil slinging work is completed, the impregnation basket 9 and the auxiliary impregnation basket 10, which have completed the oil impregnation work, are completely raised to the outside of the impregnation tank 1 to facilitate the subsequent wire retrieval by personnel. In addition, when the coil is impregnating the oil, the auxiliary drive motor can also be turned on to shake the impregnating coil and make its oil impregnation effect better. When the coil is impregnating the oil, the drive disk 19 does not extend into the oil. The motor designed is a speed-regulating motor.

[0033] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
