Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, specifically to a micro-arc oxidation composite electroplating device for automotive sensor housings. Background Technology

[0002] The micro-arc oxidation composite electroplating device for automotive sensor housings is a device used for surface treatment of automotive sensor housings. It mainly combines two processes: micro-arc oxidation and electroplating. Through a specific device design, a micro-arc oxidation treatment is first performed on the surface of the housing to form a ceramic layer, and then a metal layer is further plated through an electroplating process to improve the housing's corrosion resistance, wear resistance, and insulation properties.

[0003] The working principle of the micro-arc oxidation composite electroplating device for automotive sensor housings is as follows: the sensor housing is immersed in an electrolyte as the anode. After a pulse power supply is applied, an initial oxide film first forms on the surface of the housing. As the voltage increases, electrochemical breakdown occurs at the weak points of the oxide film, generating a micro-arc discharge. This causes the metal surface to react with the electrolyte to form a ceramic-like oxide film, improving surface hardness and wear resistance.

[0004] Traditional micro-arc oxidation composite electroplating equipment for automotive sensor housings encounters a problem during the micro-arc oxidation composite electroplating process. When the sensor is immersed in the electrolyte for electroplating, the voltage increases and the electrolyte generates micro-arc discharge, which raises the temperature of the electrolyte. Excessive electrolyte temperature can negatively impact subsequent electroplating processes of the automotive sensor housing. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a micro-arc oxidation composite electroplating device for automotive sensor housings, including an electrolytic cell 1, a control box 11 fixedly connected to one end of the electrolytic cell 1, a storage component 2 disposed at the end of the electrolytic cell 1 away from the control box 11, and the storage component 2 including a storage box 21 fixedly connected to the end of the electrolytic cell 1 away from the control box 11, a drain port 22 fixedly connected to the lower end of the storage box 21, and a liquid inlet 23 fixedly connected to the upper end of the storage box 21, an extraction component 3 disposed at the lower end of the storage box 21, a heat conduction component 4 disposed at the upper end of the extraction component 3, a heat exchange component 5 disposed at the upper end of the storage box 21, a blower component 6 disposed in the middle of the heat exchange component 5, and a stirring component 7 disposed at the lower end of the blower component 6. By cooperating with the storage component 2 and the extraction component 3, the temperature of the electrolyte can be cooled by heat conduction during the micro-arc oxidation composite processing of the automotive sensor, reducing the impact caused by high temperature.

[0026] like Figure 2 As shown, the extraction component 3 includes a water pump 31 fixedly connected to one end of the storage tank 21 near the electrolytic cell 1, and a water pump 32 fixedly connected to the other end of the water pump 31 away from the storage tank 21. After the water pump 32 is started, it extracts the cooling water in the storage tank 21 through the water pump 31, and the extracted cooling water is injected into the diversion tank 41 through the drain outlet.

[0027] like Figure 2As shown, the heat-conducting component 4 includes a diversion channel 41 opened on the outer side of the middle of the water pump 32, and a guide channel 42 opened at the end of the diversion channel 41 away from the water pump 32. A spray nozzle 43 is provided at the end of the guide channel 42 away from the diversion channel 41, and the end of the spray nozzle 43 near the electrolytic cell 1 is fixedly connected to the storage tank 21. The extracted cooling water is injected into the diversion channel 41 through the drain outlet, and then diverted into the guide channel 42 through the diversion channel 41. When the cooling water flows in the guide channel 42, it absorbs the heat of the electrolyte in the electrolytic cell 1.

[0028] like Figure 2 As shown, multiple sets of diversion channels 42 are arrayed inside the electrolytic cell 1, and the diversion channel 41 is connected to the outlet of the water pump 32.

[0029] like Figure 1 As shown, the heat exchange assembly 5 includes a first filter 51 fixedly connected to the inner side of the upper end of the storage tank 21, and a second filter 52 fixedly connected to the inner side of the end of the storage tank 21 away from the electrolytic cell 1.

[0030] like Figure 1 and Figure 2 As shown, the blower assembly 6 includes a mounting plate 61 fixedly connected to the inner side of the middle of the first filter 51, and a motor 62 fixedly connected to the upper end of the mounting plate 61. The output shaft of the motor 62 passes through the mounting plate 61 and is fixedly connected to a fan 63. The output shaft of the motor 62 drives the fan 63 and the rotating rod 71 to rotate. After the fan 63 rotates, it agitates the air in the storage box 21, so that the outside air enters the storage box 21 after being filtered by the second filter 52. Then, the air in the storage box 21 forms an airflow and is discharged from the first filter 51, thereby dissipating the heat absorbed by the cooling water in the storage box 21.

[0031] like Figure 2 As shown, the stirring assembly 7 includes a rotating rod 71 fixedly connected to the lower end of the fan 63, and a stirring paddle 72 fixedly connected to the lower end of the rotating rod 71. The rotating rod 71 drives the stirring paddle 72 to rotate, and the rotation of the stirring paddle 72 is used to stir the cooling water in the storage tank 21 to accelerate the heat dissipation effect.

[0032] Working principle: During the micro-arc oxidation composite electroplating process of automotive sensor housing, when it is necessary to cool the electrolyte in electrolytic tank 1, the water pump 32 and motor 62 are started first. After the water pump 32 starts, it draws cooling water from the storage tank 21 through the water pipe 31. The drawn cooling water is injected into the diversion tank 41 through the drain outlet, and then diverted into the guide tank 42 through the diversion tank 41. When the cooling water flows in the guide tank 42, it absorbs the heat of the electrolyte in electrolytic tank 1. The cooled water after absorbing heat is sprayed out through the spray nozzle 43 and falls into the storage tank 21 in a sheet-like manner. At this time, the operation of motor 62 is used to transport the cooling water. The output shaft drives the fan 63 and the rotating rod 71 to rotate. After the fan 63 rotates, it agitates the air in the storage tank 21, allowing the outside air to enter the storage tank 21 after being filtered by the second filter 52. Then, the air in the storage tank 21 forms an airflow and is discharged from the first filter 51, thereby dissipating the heat absorbed by the cooling water in the storage tank 21. At the same time, the rotating rod 71 drives the stirring paddle 72 to agitate the cooling water, accelerating the heat dissipation effect. Coolant can be added to the storage tank 21 through the liquid inlet 23, or the dirty cooling water in the storage tank 21 can be drained and replaced by opening the drain port 22.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
