[0001] This utility model relates to the field of PCBA board cleaning technology, specifically to a fully automatic rotary cleaning machine. Background Technology

[0002] PCBA boards are important electronic components, serving as the support for electronic components and providing the connection for electronic component circuitry. Because they are manufactured using electronic printing technology, they are called "printed" circuit boards. During the production process, PCBA boards require soldering with solder paste and flux. However, flux residues can remain, containing organic acids and decomposable ionic residues. The organic acids can corrode the PCBA board, while the ionic residues can cause short circuits during electrical conduction, rendering the PCBA board unusable. Therefore, PCBA boards must be cleaned before use, requiring the use of a PCBA board cleaning machine.

[0021] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-4 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] See Figure 1-4 A fully automatic rotary cleaning machine includes a body 1, a cleaning chamber 11 installed in the top of the body 1, a turntable 3 installed at the bottom of the cleaning chamber 11, and a motor 8 for driving the turntable 3 to rotate. The top of the turntable 3 has a plurality of cleaning holes 31 evenly opened in the circumferential direction. Each cleaning hole 31 has a fixture 32 for fixing PCBA boards installed on its top. The inner wall of the cleaning chamber 11 has spray bars 4 installed horizontally above and below the turntable 3. An air knife 41 is installed on one side of the spray bar 4 below the turntable 3. Each spray bar 4 has a row of nozzles 42 installed on the side facing the fixture 32. An air outlet 43 is opened on the side of the air knife 41 facing the fixture 32. Heating plates 2 are installed on the left, right and rear outer walls of the cleaning chamber 11.

[0023] This fully automatic rotary cleaning machine uses a fixture 32 to fix the PCBA boards to be cleaned to the top of the turntable 3, preventing the PCBA boards from colliding and damaging each other during the cleaning process. The motor 8 drives the turntable 3 to rotate, while spray bars 4 positioned above and below the turntable 3 clean the PCBA boards. After cleaning, heating plates 2 heat the boards, and air knives 41 positioned below the turntable 3 dry them. The rotating turntable 3 drives the PCBA boards to rotate, achieving thorough cleaning and drying without any blind spots. Furthermore, the multiple heating plates 2 installed on the outer wall of the cleaning chamber 11 accelerate the evaporation of moisture from the PCBA board surface, shortening the drying time and improving the cleaning efficiency of the PCBA board cleaning machine.

[0024] In this embodiment, a bottom chamber 12 is provided inside the bottom of the machine body 1. A water pump 5 is installed at the bottom of the bottom chamber 12. The water pump 5 is connected to the water inlet of each of the spray bars 4 through a water supply pipe (not shown in the figure). A valve switch 51 is installed at the water outlet of the water pump 5, and the other end of the valve switch 51 is sleeved with the water supply pipe. The water pump 5 provides the necessary cleaning impact force to the nozzles 42 by pressurizing, so that the cleaning agent sprayed from the nozzles 42 can achieve a cleaning effect on the PCBA board. The valve switch 51 can control the start and stop of the cleaning process.

[0025] In this embodiment, a fan 44 is installed on the top of the cleaning chamber 11, and the air outlet of the fan 44 is connected to the air inlet of the air knife 41 through a pipe (not shown in the figure). By setting the fan 44 to provide a continuous and stable pressurized airflow to the air knife 41, the drying effect is enhanced and the drying time is shortened.

[0026] In this embodiment, the front side of the cleaning chamber 11 has an opening, and a sealing door 6 is installed at the opening. A cylinder 61 for driving the sealing door 6 to move up and down is installed at the bottom of the sealing door 6. The top of the piston rod of the cylinder 61 is fixedly connected to the bottom of the sealing door 6, and the bottom of the cylinder 61 is fixedly connected to the bottom inner wall of the bottom chamber 12. The above structure can prevent the cleaning fluid in the cleaning chamber 11 from leaking out from the sealing door 6, and the vertically movable sealing door 6 can facilitate the entry and exit of PCBA boards from the cleaning chamber.

[0027] In this embodiment, the fixture 32 includes fixing blocks 321 fixed to the left and right sides of each cleaning hole 31 and fixing plates 322 horizontally installed between the two fixing blocks 321. Each fixing block 321 has a groove 323 on its inner side, and each fixing plate 322 has its left and right sides respectively embedded in the corresponding groove 323. Each fixing plate 322 has multiple drainage holes 324 on its top. This structure can fix the PCBA board to the top of the turntable 3.

[0028] In this embodiment, an exhaust vent 7 is provided at the top of the rear inner wall of the cleaning chamber 11, and the exhaust vent 7 is connected to an exhaust pipe 71. By setting the exhaust vent 7 and the exhaust pipe 71, the humid air in the cleaning chamber 11 can be discharged, reducing the air humidity in the cleaning chamber 11, accelerating the evaporation of moisture on the PCBA board surface, and shortening the drying time.

[0029] In this embodiment, a drain trough 13 is provided at the bottom of the cleaning chamber 11, and a drain pipe 14 is connected to the bottom of the drain trough 13. A filter screen 15 is fixed inside the drain trough 13. The above structure can discharge the cleaning liquid with stains from the cleaning chamber 11, and the filter screen 15 can prevent the drain pipe 14 from becoming clogged.

[0030] In this embodiment, a splash guard 16 is fixed at the bottom of the cleaning chamber 11 corresponding to the position of the turntable 3. The splash guard 16 can prevent the cleaning fluid from splashing everywhere.

[0031] In this embodiment, the sealing door 6 is made of transparent material. The transparent material of the sealing door 6 allows for easy operator observation and enables quick handling of any abnormalities that occur during the cleaning process.

[0032] In this embodiment, the bottom of the machine body 1 is equipped with multiple casters 9 with brakes and multiple height-adjustable support feet 91. The support frame provides support for the cleaning machine, and the casters 9 with brakes facilitate the movement of the cleaning machine.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
