Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, specifically relating to the cleaning of a flat workpiece with multiple screw holes. Background Technology

[0002] Due to the large number of screw holes on the surface of electronic control housings and some multi-screw hole parts used in new energy vehicles, impurities can hide inside these holes during cleaning, resulting in poor cleaning effects. The traditional method involves blowing away impurities from the workpiece surface using an air blowing mechanism, followed by cleaning with a spray, and then drying the workpiece again with air blowing. However, during the initial blowing of impurities from the workpiece surface, it is difficult to blow out the impurities hidden inside the screw holes, thus affecting the cleaning effect. Since there are a large number of workpieces to clean when cleaning electronic control housings and multi-screw hole parts, we have developed a cleaning device that can target and blow away impurities inside the screw holes.

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.

[0023] Please see Figures 1-7 The present invention provides the following technical solution: a cleaning device for an electrical control housing and multi-screw hole parts, including a housing 1, a cleaning chamber 2 is provided on one side of the top of the housing 1, a sealing door 3 is installed on the front of the cleaning chamber 2, a funnel 4 is installed at the bottom of the cleaning chamber 2, a lifting cleaning assembly 5 is installed on the back inside the cleaning chamber 2, a rotating assembly 6 for clamping and rotating the workpiece is provided at the bottom of the cleaning chamber 2, fixed-point spraying and blowing assemblies 7 are installed on both inner walls of the cleaning chamber 2, a purification assembly 8 for filtering and purifying wastewater is installed at the bottom of the housing 1, multiple pneumatic ball valves 9 are installed at the top of the housing 1, and a sewage tank 10 and a clean water tank 11 are installed at the bottom of the back of the housing 1, with the top of the sewage tank 10 open at the bottom of the outlet pipe of the funnel 4.

[0024] In this embodiment, the lifting and cleaning assembly 5 includes a first horizontal plate 51 installed at the bottom of the cleaning chamber 2. Two first guide rods 52 are installed at the top of the first horizontal plate 51. A first mounting plate 53 is installed at the top of the first guide rods 52. A first push rod 54 is installed at the middle of the top of the first mounting plate 53. The telescopic end of the first push rod 54 extends to the bottom of the first mounting plate 53 and is connected to the lifting component 55. A first guide sleeve 56 is installed at both ends of the lifting component 55. The first guide sleeve 56 is slidably connected to the first guide rod 52. Two cleaning pipes 57 are installed on the front of the lifting component 55. Both cleaning pipes 57 are U-shaped. A first cleaning nozzle 58 is installed on the inner wall of the opposite side of the two cleaning pipes 57. The cleaning pipe 57 located at the top is connected to the purification assembly 8, and the cleaning pipe 57 located at the bottom is connected to one of the pneumatic ball valves 9.

[0025] Specifically, the first push rod 54 can push the lifting component 55 to move up and down. If the workpiece is a flat and thin workpiece, the workpiece will be located inside the cleaning pipe 57 after being clamped and fixed by the clamp 66. Therefore, the water purified by the purification component 8 can spray and clean the surface of the workpiece through the first cleaning nozzle 58. The pneumatic ball valve 9, in conjunction with the first cleaning nozzle 58, can also blow away impurities on the surface of the workpiece and dry the moisture on the surface of the workpiece.

[0026] In this embodiment, the rotating assembly 6 includes a second horizontal plate 61 installed at the bottom of the housing 1 and located at the bottom of the funnel 4. A fixing frame 62 is installed at the bottom of the second horizontal plate 61, and a reducer 63 is installed at the bottom of the fixing frame 62. The input end of the reducer 63 is connected to the servo motor 64, and the output end of the reducer 63 is connected to the rotating shaft 65. An opening is provided on the surface of the second horizontal plate 61, and the rotating shaft 65 is disposed in the opening. An extension tube 12 is provided on the surface of the funnel 4, and the rotating shaft 65 also passes through the extension tube 12 and is disposed in the cleaning chamber 2. A clamp 66 for clamping the workpiece is installed at the top of the rotating shaft 65.

[0027] Specifically, the fixture 66 can clamp and fix the workpiece. If the workpiece is flat and thin, the servo motor 64 does not work, and the workpiece remains stationary. The fixed-point spray blowing assembly 7 blows away impurities in the screw holes of the workpiece at a fixed point, and then spray cleaning is performed. If the workpiece is polygonal, the servo motor 64 drives the rotating shaft 65, causing the fixture 66 to rotate the workpiece. The spray cleaning assembly 7 can thoroughly clean the workpiece and dry its surface. The servo motor 64 can stop the workpiece at a specified angle, so that the screw holes on the workpiece surface are directly facing the second cleaning nozzle 76 of the spray cleaning assembly 7. In this way, water and impurities in the screw holes of the workpiece can be blown away.

[0028] In this embodiment, the fixed-point spray blowing assembly 7 includes a second mounting plate 71 installed on the inner walls of both sides of the cleaning chamber 2. Two second guide sleeves 72 are embedded in the surface of the second mounting plate 71. A second guide rod 73 is slidably installed inside the second guide sleeve 72. One end of the second guide rod 73 is connected to the cleaning component 74, and the other end of the second guide rod 73 is fixedly connected to the connecting plate 75. The cleaning component 74 has an inner cavity. A plurality of second cleaning nozzles 76 communicating with the cleaning cavity are installed on one side of the cleaning component 74, and a plurality of second cleaning nozzles 76 are installed on the other side of the cleaning component 74. A pneumatic three-way ball valve is connected to the cleaning chamber. The purification component 8 and another pneumatic ball valve 9 are respectively connected to the pneumatic three-way ball valve. A second push rod 77 is installed on the back of the second mounting plate 71. The telescopic end of the second push rod 77 passes through the second mounting plate 71 and is connected to the cleaning component 74. The second push rod 77, the second guide rod 73 and the connecting plate 75 are all located outside the cleaning chamber 2. A protective cover 78 is installed on the second mounting plate 71 on one side of the second push rod 77. The second push rod 77, the second guide rod 73 and the connecting plate 75 are all located inside the protective cover 78.

[0029] Specifically, the second push rod 77 pushes the cleaning component 74 so that the second cleaning nozzle 76 can approach the workpiece, thereby enabling targeted removal of impurities and water from the screw holes of the workpiece. The pneumatic three-way ball valve can switch the working mode of the targeted spray and blowing assembly 7, allowing for free switching between spraying and blowing. The protective cover 78 protects the second push rod 77, the second guide rod 73, and the connecting plate 75.

[0030] In this embodiment, the purification component 8 includes a filter water pump 81, a first filter 82, a spray water pump 83, and a second filter 84 disposed at the bottom of the chassis 1. The water pump 81 is connected to the sewage tank 10. The water inlet of the first filter 82 is connected to the water pumping end of the filter water pump 81. The water outlet of the first filter 82 is connected to the clean water tank 11. The water pump 83 is connected to the clean water tank 11. The water pump 83 is connected to the water inlet of the second filter 84. The water outlet of the second filter 84 is connected to the cleaning pipe 57 located at the top of the lifting cleaning component 5 and a pneumatic three-way ball valve through the water outlet pipe. The first filter 82 is a 50μm filter, and the second filter 84 is a 25μm filter.

[0031] Specifically, the wastewater generated during cleaning enters the wastewater tank 10 through the funnel 4. The filter pump 81 pumps the wastewater into the first filter 82 for primary filtration, where large particles in the wastewater are filtered out. The water after primary filtration then enters the clean water tank 11. The spray pump 83 pumps the water into the second filter 84 for secondary filtration, where fine particles are removed. The filtered water is then sprayed out through the first cleaning nozzle 58 and the second cleaning nozzle 76. This method enables the device to recycle wastewater, effectively reducing water waste.

[0032] In this embodiment, a fan 13 is installed on the top of the casing 1, and a mist suction pipe 14 connected to the top of the cleaning chamber 2 is installed on the top of the casing 1. A mist exhaust square pipe 15 is installed on the side of the mist suction pipe 14 on the top of the casing 1. The input end of the fan 13 is connected to the mist suction pipe 14, and the output end of the fan 13 is connected to the mist exhaust square pipe 15.

[0033] Specifically, since a large amount of water mist is generated when spraying and blowing air onto the workpiece, the water mist is drawn out from the cleaning chamber 2 by the fan 13 in conjunction with the mist suction pipe 14 and discharged through the mist exhaust square pipe 15, thereby improving the dryness of the workpiece.

[0034] In this embodiment, the distribution position of the second cleaning nozzle 76 matches the distribution position of the screw holes on the workpiece surface.

[0035] Working principle: If the workpiece is flat and thin, it is clamped and fixed by the fixture 66, and the servo motor 64 keeps the workpiece in a vertical position within the cleaning tube 57. Then, the pneumatic three-way ball valve adjusts the fixed-point spray blowing assembly 7 to the blowing mode. The second push rod 77 pushes the second cleaning nozzle 76 to the screw hole on the workpiece surface and blows air into the screw hole to remove impurities. After that, the pneumatic three-way ball valve adjusts the fixed-point spray blowing assembly 7 to the spray mode to spray clean the workpiece surface. This step is the initial cleaning. Then, the lifting cleaning assembly 5 sprays the workpiece surface again for fine cleaning. After washing, the surface of the workpiece is dried by blowing air. Then, the second cleaning nozzle 76 is pushed to the screw hole on the surface of the workpiece by the second push rod 77 and blows air into the screw hole to dry the water inside the screw hole, thereby effectively improving the cleaning effect of the workpiece. If the workpiece is polygonal, during cleaning, the lifting cleaning component 5 remains stationary, and the workpiece is rotated by the rotating component 6. The surface of the workpiece is first cleaned by the fixed-point spray blowing component 7, and then the workpiece is dried by the fixed-point spray blowing component 7. Afterwards, the second push rod 77 pushes the second cleaning nozzle 76 close to the workpiece, and the rotating component 6 rotates the workpiece to the angle of blowing the screw hole to dry the impurities and water inside the screw hole.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
