Abstract
Description
Technical Field
[0001] This utility model relates to an immersion washing device, specifically an immersion washing device for circuit board production, belonging to the field of circuit board production technology. Background Technology
[0002] Circuit board immersion cleaning refers to soaking circuit boards in a cleaning solution to remove surface dirt and impurities through physical or chemical action. This method can effectively clean circuit boards, but it is important to pay attention to the correct operating procedures and the selection of the cleaning solution to avoid damaging the circuit board. Proper immersion cleaning can ensure the integrity and functionality of the circuit board.
[0003] A search revealed a circuit board immersion washing device disclosed in Chinese Patent Publication No. CN206882274U, which includes a storage tank for providing the treatment liquid and a container for holding the treatment liquid. This device allows the treatment liquid to flow naturally from above into the treatment tank and then flow back from below to the storage tank, ensuring sufficient exchange of the treatment liquid within the treatment tank and guaranteeing good uniformity of ion concentration in the treatment liquid.
[0004] While the above-mentioned solution allows for the circulation and reuse of the working fluid, impurities detached from the circuit board surface during the immersion process will mix into the working fluid. If an effective filtration mechanism is not established, these contaminants will re-adhere to the circuit board surface during the circulation process. This will not only lead to a decrease in cleaning efficiency, but also directly affect the cleanliness of the circuit board, thus compromising the quality and electrical performance of the circuit board. To address these issues, we provide an immersion washing device for circuit board production. Utility Model Content

[0026] This utility model provides an immersion washing device for circuit board production.
[0027] Please see Figure 1 The device includes a filter box 1 and a washing tank 2. The bottom surface of the washing tank 2 is fixedly connected to the filter box 1. The outer surface of the filter box 1 is electrically connected to the municipal power supply through a wire, thereby enabling the power supply to the electrical equipment in this application. A solenoid valve is installed at the liquid outlet at the bottom of the washing tank 2. By opening the solenoid valve, the working fluid in the washing tank 2 can be guided to the filter box 1. The solenoid valve is a common prior art technology, so it is not shown in the figure and will not be described in detail in this application. The top opening of the washing tank 2 is hinged with a cover plate, and by opening the cover plate, it is convenient to add working fluid to the washing tank 2.
[0028] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The filter box 1 is equipped with a filter mechanism 3. The filter mechanism 3 includes a fixed frame 301. The outer surface of the fixed frame 301 is fixedly connected to the filter box 1. The inner wall of the fixed frame 301 is fixedly connected with a first filter plate 302 and a second filter plate 303. Through the arrangement of the first filter plate 302 and the second filter plate 303, the working fluid in the filter box 1 can be effectively filtered.
[0029] A drive roller 304 is rotatably connected to the inner wall of the fixed frame 301. A reciprocating slip ring 305 is slidably connected to the outer surface of the drive roller 304. A cleaning rod 306 is fixedly connected to the bottom surface of the reciprocating slip ring 305. The outer surface of the cleaning rod 306 is slidably connected to the filter box 1. An auger push roller 307 is rotatably connected to the inner wall of the filter box 1. A cleaning brush is installed on the bottom surface of the cleaning rod 306. The cleaning brush allows for more thorough cleaning of impurities on the surface of the first filter plate 302 when the cleaning rod 306 is driven. A rotary motor is fixedly installed on the inner wall of the filter box 1. The output end of the rotary motor is fixedly connected to the auger push roller 307. By turning on the rotary motor to drive the auger push roller 307 to rotate, not only can the impurities attached to the surface of the second filter plate 303 be scraped and cleaned, but the impurities can also be pushed evenly to the retention box 311 for centralized retention.
[0030] The outer surface of the drive roller 304 is provided with a reciprocating groove 308. An adjusting frame 309 is slidably connected to the inner wall of the reciprocating groove 308. The outer surface of the adjusting frame 309 is rotatably connected to the reciprocating slip ring 305. Through the synergistic effect of the reciprocating groove 308 and the adjusting frame 309, when the drive roller 304 is driven to rotate, the reciprocating slip ring 305 can be driven to slide back and forth synchronously on the surface of the drive roller 304.
[0031] A first drive motor 310 is fixedly connected to the inner wall of the fixed frame 301. The output end of the first drive motor 310 is fixedly connected to the drive roller 304. By turning on the first drive motor 310, the drive roller 304 can be effectively driven to rotate.
[0032] A retention box 311 is fixedly connected to the outer surface of the filter box 1, and a pump body 312 is fixedly connected to the inner bottom wall of the filter box 1. The retention box 311 can effectively soak and retain the filtered impurities, making it convenient for staff to clean them in a centralized manner.
[0033] A circulation pipe 313 is fixedly connected to the inner wall of the filter box 1. One end of the circulation pipe 313 is fixedly connected to the output end of the pump body 312, and the end of the circulation pipe 313 away from the pump body 312 is fixedly connected to the immersion tank 2. By turning on the pump body 312, the working liquid filtered in the filter box 1 can be effectively pumped to the immersion tank 2 through the circulation pipe 313 for reuse. The liquid delivery speed of the pump body 312 to the immersion tank 2 through the circulation pipe 313 is greater than the liquid outlet speed at the bottom of the immersion tank 2, so that the working liquid in the immersion tank 2 can always soak and clean the circuit board.
[0034] Please refer to it again. Figure 2 and Figure 5 The washing tank 2 is equipped with a turning mechanism 4 inside. The turning mechanism 4 includes an electric push rod 401. The outer surface of the electric push rod 401 is rotatably connected to the washing tank 2. The surface of the filter box 1 is equipped with a control button for the electric push rod 401. The electric push rod 401 can be opened and closed by the control button.
[0035] The telescopic end of the electric actuator 401 is fixedly connected to a connecting plate 402, and a fixing clip 403 is fixedly connected to the outer surface of the connecting plate 402. The fixing clip 403 is a common clamping component in the prior art, and will not be described in detail in this application.
[0036] The inner wall of the immersion tank 2 is fixedly connected to a second drive motor 404. The output end of the second drive motor 404 is fixedly connected to the electric push rod 401. The first drive motor 310, pump body 312, electric push rod 401, second drive motor 404 and the mentioned rotating motor are all common electrical devices in the prior art. This application will not elaborate on their models or internal structures. They can also be replaced by other power sources.
[0037] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.
[0038] In use, this invention works as follows: First, the two electric actuators 401 are activated, causing the two connecting plates 402 to move closer or further apart, adjusting the distance between the two connecting plates 402 to match the size of the circuit board. Next, the circuit board is clamped and fixed by the fixing clamp 403, and then the working solution is introduced into the immersion tank 2. Then, the second drive motor 404 is activated to drive the electric actuators 401 to rotate, causing the circuit board to tumble during the cleaning process in the immersion tank 2, allowing the working solution to contact the circuit board more evenly. After cleaning, the working solution is guided to the filter box 1 by opening the solenoid valve at the bottom outlet of the immersion tank 2. The working solution entering the filter box 1 undergoes initial filtration through the first filter plate 302. At this time, the first drive motor 310 is activated to drive the drive roller 304 to rotate. The rotation of the drive roller 304, combined with the synergistic effect of the reciprocating slide groove 308 and the adjusting frame 309, effectively drives the reciprocating slip ring. The reciprocating slip ring 305 slides back and forth on the surface of the drive roller 304. The sliding of the reciprocating slip ring 305 drives the cleaning rod 306 to move horizontally back and forth to clean the impurities filtered out from the top surface of the first filter plate 302. The impurities are effectively pushed to both sides of the filter box 1. When the impurities are introduced into both sides of the filter box 1, they can be filtered a second time by the second filter plate 303, so that the impurities in the working fluid are filtered more thoroughly. The filtered working fluid can be effectively guided to the immersion tank 2 for reuse through the cooperation of the pump body 312 and the circulation pipe 313. The impurities in the filter box 1 are driven by the rotating motor in the filter box 1 to rotate the auger push roller 307. The rotation of the auger push roller 307 effectively pushes the impurities to the retention box 311 for centralized retention. This device significantly improves the cleaning efficiency of the circuit board and ensures that the surface cleanliness of the circuit board reaches a higher standard, thereby effectively guaranteeing the production quality and electrical performance of the circuit board.
