[0002] The power module, namely, Module Intelligent Power System (MIPS), is a kind of power driving product combining power electronics and integrated circuit technology. The MIPS not only integrates power switching devices and driving circuits, but also internally contains fault detection circuits such as overvoltage, overcurrent and overheat, and can send detection signals to the CPU or DSP for interrupt processing. It is composed of high-speed low-power chips, optimized gate-level driving circuits and fast protection circuits, so that even if load accidents or improper use occur, the MIPS itself will not be damaged.

[0038] As shown in Figures 1-2 A circulating cleaning system suitable for power module, comprising evaporation tank 1, feeding platform 2, cleaning tank 3 and discharging platform 4 arranged in sequence;

[0039] The evaporation tank 1 and the cleaning tank 3 are communicated by reflux pipe one 10, the evaporation tank 1 is further communicated with exhaust pipe 20 and cooling pipe 30 in sequence, the end of the cooling pipe 30 is provided with recovery disc 5, the cleaning tank 3 and the recovery disc 5 are communicated by reflux pipe two 40;

[0040] The evaporation tank 1 and the exhaust pipe 20 are provided with heating and exhaust device 6, the cooling pipe 30 is provided with cooling and drainage device 7;

[0041] The feeding platform 2, the cleaning tank 3 and the discharging platform 4 are provided with conveying device 8 above, the conveying device 8 is used for conveying the products to be cleaned in the conveying sequence of the feeding platform 2, the cleaning tank 3 and the discharging platform 4.

[0042] Specifically, the plurality of cleaning tanks 3 are filled with cleaning agent, and the conveying device 8 is used to sequentially send the products to be cleaned on the feeding platform 2 into the cleaning tanks 3 for immersion cleaning, and then send the cleaned products from the cleaning tanks 3 to the discharging platform 4.

[0043] The waste liquid generated when the cleaning tank 3 cleans the products to be cleaned is returned to the evaporation tank 1 through the reflux pipe two 10, and the waste liquid is heated by the heating and air extraction device 6 arranged at the bottom of the evaporation tank 1, so that the effective cleaning agent components in the waste liquid are vaporized, and then the vaporized cleaning agent is conveyed to the cooling pipe 30 through the air extraction pipe 20, so that the vaporized cleaning agent is cooled and liquefied by the cooling and drainage device 7 arranged inside, and then the liquefied cleaning agent is conveyed to the collection device 5, and then returned to the cleaning tank 3 through the reflux pipe two 40, so that the recycling of the cleaning agent is completed.

[0044] In summary, the conveying device 8 can automatically drive the products to be cleaned on the feeding platform 2 to clean in the cleaning tank 3, reducing the labor intensity of the user; and the cooperation between the heating and air extraction device 6 and the cooling and drainage device 7 purifies and recycles the contaminated cleaning agent waste liquid, so that the filter can be replaced without the need to configure a filter, greatly saving the equipment cost and time cost, and further improving the production efficiency.

[0045] Further, the number of the cleaning tanks 3 is at least three, the bottom of each of the plurality of cleaning tanks 3 is provided with an ultrasonic vibrator, and the heights of the openings of the plurality of cleaning tanks 3 are equally increased from one end close to the feeding platform 2 to one end close to the discharging platform 4.

[0046] Specifically, the plurality of cleaning tanks 3 filled with cleaning agent are used to synchronously immerse and clean the products to be cleaned in a moving state by the conveying device 8, and the overflowed cleaning agent during the immersion and cleaning flows from the higher cleaning tank 3 to the lower cleaning tank 3, and then returns to the evaporation tank 1 through the reflux pipe one 10, and then returns to the higher cleaning tank 3 through the reflux pipe two 40 after vaporization and liquefaction.

[0047] The design can effectively avoid the frequent addition or pouring of cleaning agent in the cleaning tank 3, reduce the labor intensity of the user, improve the user experience, realize the circulation of the cleaning agent, and effectively save the cost.

[0048] Further, the heating and air extraction device 6 includes a heating wire 61 and an air extractor 62.

[0049] The heating wire 61 is arranged at the bottom of the evaporation tank 1, and the air extractor 62 is arranged inside the air extraction pipe 20.

[0050] Specifically, by installing a heating wire 61 at the bottom of the evaporation tank 1, the cleaning agent in the evaporation tank 1 is heated to the temperature of water vapor. The water vapor flows upward, and the exhaust fan 62 located inside the exhaust pipe 20 can accelerate the flow of water vapor to the cooling guide device 7 in the cooling pipe 30, thereby improving efficiency.

[0051] To further explain, the cooling diversion device 7 includes a condenser 71, a condenser tube 72, and a compressor;

[0052] The condenser 71 is located at the beginning of the cooling pipe 30, and the compressor is located at the end of the cooling pipe 30. The condenser 71 and the compressor are connected through the condenser pipe 72.

[0053] Specifically, the condenser 71 is made of aluminum or copper, and has a uniformly distributed fin-like structure inside to increase the surface area and enable rapid condensation of gas;

[0054] The condenser 71, in conjunction with the condenser tube 72, liquefies the vaporized cleaning agent, and the compressor accelerates the liquefaction rate.

[0055] To further explain, the condenser tube 72 is bent and wraps around the surface of the cooling tube 30 along its length. This increases the heat exchange area of ​​the cooling tube 30, resulting in better heat exchange and faster condensation.

[0056] To further explain, such as Figure 3 As shown, the collection device 5 includes a collection frame 51, a liquid collection edge 52 extending upward from the center of the collection frame 51, an exhaust port 55 forming the top of the liquid collection edge 52, and a liquid collection groove 53 formed by the bottom of the liquid collection edge 52 and the connection between it and the collection frame 51. The liquid collection groove 53 is provided with a return hole 54, which is connected to the return pipe 40.

[0057] Specifically, the liquefied cleaning agent is centrally recovered through the collection channel 52 and the collection tank 53, while the unliquefied cleaning agent is discharged through the exhaust port 55. The centrally recovered cleaning agent is guided through the return hole 54 into the return pipe 40, thereby transporting the recovered cleaning agent to the cleaning tank 3 through the return pipe 40, completing the circulation of the cleaning agent.

[0058] To further explain, the cross-section of the liquid collection line 52 is conical. This conical design increases the contact area with the unliquefied cleaning agent, allowing it to adhere to the surface of the liquid collection line 52 and transform into liquefied cleaning agent, thus improving recovery efficiency. Simultaneously, it does not affect internal venting, ensuring safe operation.

[0059] Further, the conveying mechanism 4 comprises horizontal guide rails 81, horizontal drive machines 82 are installed on the horizontal guide rails 81, support plates 83 are slidably installed on the horizontal guide rails 81, and the support plates 83 are provided with vertical guide rails 84 on both sides.

[0060] Vertical drive machines 85 are installed on the two vertical guide rails 84, and mechanical arms 86 are welded and fixed on one side of the two vertical drive machines 85, and the two mechanical arms 86 are equidistantly installed with hanging assemblies 9.

[0061] Further, the hanging assembly 9 comprises a cleaning basket 91, a hanging rod 92 and a plurality of hooks 93.

[0062] The cleaning basket 91 is a screen-like structure, and the cleaning basket 91 is used for placing products to be cleaned.

[0063] The two ends of the hanging rod 92 are respectively arranged on the two mechanical arms 86, the middle part of the hanging rod 92 is equidistantly arranged on the mechanical arms 86, and the hooks 93 are used for hooking the cleaning basket 91.

[0064] Specifically, when the horizontal drive machine 82 is started, the support plate 83 installed with the two vertical guide rails 84 can be driven to move, so that the mechanical arm 86 installed with the plurality of hooks 93 is translated in the horizontal direction, and the cleaning basket 91 is moved from above one cleaning tank 3 to above another cleaning tank 3.

[0065] When the two vertical drive machines 85 are started, the mechanical arm 86 installed with the plurality of hooks 93 can be driven to move vertically, and the cleaning basket 91 can be moved back and forth in the vertical direction of the corresponding cleaning tank 3.

[0066] Therefore, through the alternating cooperation of the horizontal drive machine 82 and the vertical drive machine 85, the cleaning basket 91 hung on the hooks 93 can be moved out of one cleaning tank 3 after being soaked and cleaned, and can be moved into another cleaning tank 3 for continuous soaking and cleaning, so that the synchronous movement of the plurality of cleaning baskets 91 and the synchronous cleaning of the plurality of products to be cleaned are realized, and the cleaning efficiency is improved.

[0067] The specific working principle of the present application is as follows: first, the cleaning agent is added into the plurality of cleaning tanks 3, and the product to be cleaned is placed in the cleaning basket 91 on the feeding platform 2, and then the plurality of ultrasonic transducers installed in the plurality of cleaning tanks 3 are started.

[0068] After the above preparation, start the two vertical driving machines 85 to drive the mechanical arm 86 with the multiple hooks 93 to translate in the vertical direction, so as to pull up the cleaning basket 91, and start the horizontal driving machine 82 to drive the support plate 83 with the two vertical guide rails 84 to move, so as to realize the translation of the mechanical arm 86 with the multiple hooks 93 in the horizontal direction, and move the cleaning basket 91 above one of the cleaning tanks 3, and then start the two vertical driving machines 85 again to drive the mechanical arm 86 with the multiple hooks 93 to translate in the vertical direction, so as to put the cleaning basket 91 into the cleaning tank 3 to clean the products to be cleaned in the cleaning basket 91 by the cleaning tank 3.

[0069] After the above operation, place multiple cleaning baskets 91 with products to be cleaned on the feeding platform 601 in turn, and realize the movement of the multiple cleaning baskets 91 by the alternating cooperation of the horizontal driving machine 82 and the vertical driving machine 85, so as to continuously clean the products to be cleaned. After the multiple cleaning tanks 3 are sequentially cleaned, the conveying device 4 conveys the cleaning basket 91 to the discharging platform 4.

[0070] In the above cleaning process, the waste liquid is returned to the evaporation tank 1 through the return pipe 10, and the heating wire 61 arranged at the bottom of the evaporation tank 1 heats the waste liquid to make it warm into water vapor. The water vapor flows upward, and the exhaust fan 62 located in the exhaust pipe 20 can accelerate the flow of the water vapor to the cooling and drainage device 7 in the cooling pipe 30, so that the condensed pipe 72 cooperates with the condenser 71 to liquefy the vaporized cleaning agent, and then the compressor conveys the cleaning agent to the collecting device 5, and the liquid collecting guide 52 and the liquid collecting tank 53 on the collecting device 5 concentrate and recover the liquefied cleaning agent, and the unliquefied cleaning agent is discharged through the exhaust port 55. The concentrated and recovered cleaning agent is guided to the return pipe 40 through the return hole 54, so as to convey the recovered cleaning agent to the cleaning tank 3 through the return pipe 40, and complete the circulation of the cleaning agent.

[0071] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only for the purpose of explaining the principles of the present application, and cannot be interpreted as limiting the scope of protection of the present application in any way.
