Description

Technical Field

[0001] This utility model relates to the field of ECU controller housing processing technology, and more specifically to a surface treatment device for processing ECU controller housings. Background Technology

[0002] As an important component of the electronic control unit, the ECU controller housing mainly serves to protect the internal components. In the manufacturing process of the ECU controller housing, the surface treatment stage is crucial. Considering that ECU housings are mostly made of aluminum alloy or conductive plastic, and have high requirements for structural precision, electromagnetic shielding performance, and corrosion resistance, the core function of the dedicated electrophoresis tank is to provide a controllable electrophoresis environment. Through the action of an electric field, a high-performance coating is uniformly deposited on the surface of the housing, thereby meeting the stringent standards of ECU housing in terms of corrosion resistance, insulation, electromagnetic compatibility assistance, and appearance consistency.

[0003] Traditional electrophoresis tanks tend to accumulate sediment at the bottom over long-term use. If this sediment is not cleaned regularly, it will continue to react with the electrophoresis solution, causing dissolution and contamination. This leads to a continuous decrease in the content of effective components such as resin and pigments in the solution, eventually resulting in insufficient concentration to meet the coating requirements of the ECU controller housing. In this case, the entire tank needs to be replaced with the electrophoresis solution. However, since electrophoresis solution is expensive, replacing the entire tank would result in significant economic waste.

[0004] Traditional electrophoresis tanks typically lack a self-cleaning function for the bottom of the tank without discharging the electrophoresis solution (e.g., the electrolytic tank structure disclosed in patent CN119663404B). When it is necessary to clean the sediment at the bottom, all the liquid in the tank must be drained, and then the bottom must be cleaned manually with a scraper. This cleaning method is not only time-consuming and labor-intensive, but also increases production costs when replacing the electrophoresis solution. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a surface treatment device for processing ECU controller housing, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a surface treatment device for processing ECU controller housing, including an electrophoresis tank body, a scraper slidably connected to the bottom of the electrophoresis tank body, an arc-shaped guide groove opened on the side of the scraper, a one-way valve fixedly installed inside the scraper, a suction assembly installed at the output end of the one-way valve, the output end of the suction assembly extending to the outside of the electrophoresis tank body, and the bottom of the one-way valve abutting against the bottom of the inside of the electrophoresis tank body.

[0007] Furthermore, the suction assembly includes a discharge pipe fixedly connected to the output end of one-way valve one, a suction pipe fixedly connected inside the electrophoresis tank body, a sealing ring fixedly installed inside the suction pipe, the inner wall of the sealing ring sealingly fitting the outer surface of the discharge pipe, a sealing plate fixedly connected to the end face of the discharge pipe away from one-way valve one, a material passage groove opened at the center of the discharge pipe, discharge ports equidistantly opened on the outer surface of the discharge pipe, a sealing cavity opening and closing inside the suction pipe, a discharge pipe fixedly connected to the end of the suction pipe near the sealing ring, a one-way valve two installed at the output end of the discharge pipe, a fixed seat fixedly connected to the end face of the suction pipe away from the discharge pipe, a motor fixedly installed inside the fixed seat, a threaded rod fixedly installed at the output end of the motor, and the surface of the threaded rod threadedly connected to the center of the sealing plate.

[0008] Furthermore, the end of the suction pipe away from the discharge pipe extends to the outside of the electrophoresis tank body, and the discharge pipe is "L" shaped, with the output end of the discharge pipe extending to the outside of the electrophoresis tank body.

[0009] Furthermore, the interior of the arc-shaped guide channel is connected to the interior of the material passage channel through a one-way valve, the interior of the material passage channel is connected to the interior of the sealing cavity through the discharge port, and the interior of the sealing cavity is connected to the exterior of the electrophoresis tank body through the discharge pipe.

[0010] Furthermore, the material passage is slidably connected to the inside of the sealing cavity by a sealing ring, and a sealing ring is fixedly installed on the outer surface of the sealing plate.

[0011] Furthermore, a rubber internal threaded sleeve is installed at the center of the sealing plate, and the outer surface of the threaded rod is threadedly connected to the inner wall of the rubber internal threaded sleeve, so the interior of the fixing seat is not sealed.

[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model, through the synergistic action of the scraper and the suction component, achieves efficient cleaning of the bottom sediment without discharging a large amount of electrophoresis liquid from the main body of the electrophoresis tank. Traditional equipment requires the replacement of the entire electrophoresis liquid in the tank to clean the sediment, while this equipment only results in a small amount of electrophoresis liquid loss during the cleaning process, effectively avoiding the high cost of electrophoresis liquid loss caused by replacing the entire tank, significantly reducing the total production cost of ECU controller housing surface treatment, and reducing the resource waste and environmental pressure caused by the disposal of electrophoresis liquid, which meets the requirements of economic efficiency and sustainable production.

[0013] 2. In this utility model, on the one hand, the equipment relies on a motor-driven threaded rod to automatically slide the scraper, replacing the traditional manual scraper cleaning method. It eliminates the need for manual entry into the tank or disassembly of the equipment, significantly shortening the cleaning operation time and reducing the intensity of manual labor, thus achieving automated and rapid cleaning of sediment. On the other hand, timely cleaning of sediment can prevent it from dissolving and contaminating the electrophoresis solution, effectively maintaining the stable concentration of effective components such as resin and pigment in the electrophoresis solution. This ensures uniform coating deposition on the ECU controller housing during the electrophoresis process, guaranteeing the coating quality of the housing in terms of corrosion resistance, insulation, electromagnetic compatibility, and appearance consistency, and reducing product rework problems caused by insufficient tank solution concentration.

[0016] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0017] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0018] A surface treatment apparatus for processing ECU controller housings includes an electrophoresis tank body 1. A scraper 2 is slidably connected to the bottom of the electrophoresis tank body 1. An arc-shaped guide groove 3 is provided on the side of the scraper 2. A one-way valve 4 is fixedly installed inside the scraper 2. A suction assembly 5 is installed at the output end of the one-way valve 4. The output end of the suction assembly 5 extends to the outside of the electrophoresis tank body 1. The bottom of the one-way valve 4 abuts against the bottom of the inside of the electrophoresis tank body 1.

[0019] In this implementation scheme, there is no need to discharge a large amount of electrophoretic liquid from the main body 1 of the electrophoresis tank. Only a small amount is lost during cleaning, which can achieve efficient cleaning of bottom sediment. This avoids the high cost and losses caused by replacing the entire electrophoretic liquid in the traditional method, thus reducing economic investment. Secondly, the scraper 2 slides and fits against the bottom of the electrophoresis tank body 1. Combined with the arc-shaped guide channel 3, it can actively collect sediment, prevent sediment from dispersing and contaminating the electrophoretic liquid, maintain the stable concentration of components such as resin and pigment in the electrophoretic liquid, ensure the uniformity and quality stability of the electrophoretic coating of the ECU controller housing, and reduce product rework caused by coating problems. Compared with traditional manual cleaning, it reduces the intensity of manual operation, shortens the cleaning operation time, and improves production efficiency.

[0020] Specifically, the suction assembly 5 includes a discharge pipe 51 fixedly connected to the output end of the one-way valve 4, a suction pipe 52 fixedly connected inside the electrophoresis tank body 1, a sealing ring 54 fixedly installed inside the suction pipe 52, the inner wall of the sealing ring 54 sealingly fitting against the outer surface of the discharge pipe 51, a sealing plate 59 fixedly connected to the end face of the discharge pipe 51 away from the one-way valve 4, a material passage groove 55 opened at the center of the discharge pipe 51, and discharge ports 56 equidistantly opened on the outer surface of the discharge pipe 51. The suction pipe 52 has a sealing cavity 57 that opens and closes inside. The end of the suction pipe 52 near the sealing ring 54 is fixedly connected to the discharge pipe 58. The output end of the discharge pipe 58 is equipped with a one-way valve 513. The end face of the suction pipe 52 away from the discharge pipe 51 is fixedly connected to the fixing seat 53. The fixing seat 53 is fixedly installed inside the fixing seat 53. The output end of the motor 512 is fixedly installed with a threaded rod 511. The surface of the threaded rod 511 is threadedly connected to the center of the sealing plate 59.

[0021] In this implementation scheme, the screw rod 511 is driven to rotate by the motor 512, and the screw engagement drives the sealing plate 59, the discharge pipe 51 and the scraper 2 to slide synchronously, realizing the automation of the cleaning action. There is no need for manual pushing of the scraper 2, reducing labor costs and operational risks. The sealing ring 54 inside the suction pipe 52 is sealed and fitted to the outer surface of the discharge pipe 51. Together with the sealing ring on the outer surface of the sealing plate 59, it can ensure that a stable negative pressure or high pressure environment is formed in the sealing cavity 57, ensuring the efficiency of sediment suction and discharge, and avoiding a large amount of electrophoretic liquid leakage during the cleaning process. The one-way valve 2 513 and the one-way valve 4 form a one-way passage cooperation. During the suction stage, only sediment and a small amount of electrophoretic liquid are allowed to enter the sealing cavity 57. During the discharge stage, only the mixture is allowed to be discharged from the discharge pipe 58, preventing backflow and ensuring that the cleaning process is stable and controllable.

[0022] Specifically, the end of the suction pipe 52 away from the discharge pipe 51 extends to the outside of the electrophoresis tank body 1, and the discharge pipe 58 is "L" shaped, with the output end of the discharge pipe 58 extending to the outside of the electrophoresis tank body 1.

[0023] In this implementation scheme, firstly, the end of the suction pipe 52 away from the discharge pipe 51 extends to the outside of the electrophoresis tank body 1, which facilitates the installation of drive components such as the motor 512 and the fixing seat 53 on the outside of the tank body, avoids contact between the drive components and the electrophoresis liquid, reduces the corrosion of the components by the electrophoresis liquid, extends the service life of the equipment, and reduces the difficulty of component maintenance; secondly, the discharge pipe 58 is designed in an "L" shape and the output end extends to the outside. On the one hand, it can adapt to the external structure of the electrophoresis tank body 1 to save installation space, and on the other hand, it can guide the sediment mixture to be accurately discharged to the designated collection container, avoid the discharge from polluting the surrounding environment of the equipment, and reduce the amount of subsequent cleaning work.

[0024] Specifically, the interior of the arc-shaped guide channel 3 is connected to the interior of the material passage 55 through the one-way valve 4, the interior of the material passage 55 is connected to the interior of the sealing cavity 57 through the discharge port 56, and the interior of the sealing cavity 57 is connected to the exterior of the electrophoresis tank body 1 through the discharge pipe 58.

[0025] In this implementation scheme, the arc-shaped guide channel 3, one-way valve 4, material passage 55, discharge port 56, sealing cavity 57, and discharge pipe 58 form a complete sediment transport channel, ensuring that the sediment collected by scraper 2 can be smoothly discharged through this channel, avoiding blockage at any stage and improving cleaning efficiency; the connection relationship of each component is clear, realizing an integrated process of sediment "collection-transportation-discharge", without the need for additional manual intervention to transfer sediment, further enhancing the automation level of the equipment; this connection structure is only for sediment and a small amount of electrophoresis liquid, and will not affect the normal state of the remaining electrophoresis liquid in the main body of the electrophoresis tank 1, ensuring that the electrophoresis operation of the ECU controller housing can be quickly resumed after cleaning, reducing production interruption time.

[0026] Specifically, the material feed chute 55 is slidably connected to the inside of the sealing cavity 57 by a sealing ring 54, and a sealing ring is fixedly installed on the outer surface of the sealing plate 59.

[0027] In this embodiment, the feed trough 55 slides within the sealed cavity 57 via the sealing ring 54, ensuring the sealing of the cavity 57 throughout the movement of the discharge pipe 51. This guarantees a stable negative pressure during suction and a stable high pressure during discharge, preventing weak suction or incomplete discharge due to seal failure. The sealing ring on the outer surface of the sealing plate 59 further enhances the sealing performance of the cavity 57, forming a double seal with the sealing ring 54, reducing the risk of electrophoretic fluid leakage and minimizing electrophoretic fluid loss. The sealing sliding structure reduces friction between the feed trough 55 and the suction pipe 52, extending the service life of the components, while ensuring smooth sliding of the scraper 2 and preventing incomplete collection of sediment due to jamming.

[0028] Specifically, a rubber internal threaded sleeve is installed at the center of the sealing plate 59, and the outer surface of the threaded rod 511 is threadedly connected to the inner wall of the rubber internal threaded sleeve, while the interior of the fixing seat 53 is not sealed.

[0029] In this embodiment, the rubber internal threaded sleeve inside the sealing plate 59 is connected to the threaded seal on the outer surface of the threaded rod 511. The rubber material has good elasticity and sealing properties, which can fill the thread meshing gap, enhance the sealing effect of the sealing cavity 57, and reduce wear during thread transmission, thus extending the service life of the threaded rod 511 and the sealing plate 59. Compared with the metal threaded sleeve, the rubber internal threaded sleeve can reduce transmission noise and improve the operating environment of the equipment when it is used with the threaded rod 511. The interior of the fixed seat 53 is designed to be non-sealed, which can prevent the fixed seat 53 from being deformed or damaged due to temperature changes or component operation. At the same time, it facilitates heat dissipation of the motor 512, ensures the stability of the motor 512 operation, and avoids failure due to overheating.

[0030] The working principle and usage process of this utility model are as follows: During use, after injecting the electrophoresis solution into the electrophoresis tank body 1, the ECU controller housing is placed in the liquid for electrophoresis. After prolonged use, when sediment appears at the bottom of the electrophoresis tank body 1, the starting motor 512 drives the threaded rod 511 to rotate clockwise. Through the engagement of the threaded rod 511 with the rubber internal thread sleeve at the center of the sealing plate 59, the sealing plate 59 slides to the right. As the sealing plate 59 slides to the right, the discharge pipe 51 and scraper 2 slide to the right. When the scraper 2 slides to the right, the sediment is collected inside the arc-shaped guide channel 3. When the discharge pipe 51 slides to the right, the sediment inside the sealing cavity 57 flows to the left... When the end is under negative pressure, check valve 2 513 is closed and check valve 4 is open. The sediment and a small amount of electrophoresis solution inside the arc-shaped guide channel 3 are sucked into the left end of the sealing cavity 57 through check valve 4, feed channel 55 and discharge port 56. When motor 512 drives threaded rod 511 to rotate counterclockwise, sealing plate 59 slides to the left. At this time, the sealing cavity 57 is under high pressure. Meanwhile, check valve 4 is closed and check valve 2 513 is open. Through the continuous sliding of sealing plate 59, the sediment is discharged from the output end of check valve 2 513 through discharge pipe 58, completing the rapid cleaning of sediment inside the electrophoresis tank body 1.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
