A limited sliding groove 437 matching the limited column 436 is opened on the top of the moving block 431, and a guide plate 1 44 is fixedly connected to the front end of the track platform 41, and a guide plate 2 45 is fixedly connected to the rear side of the top of the track platform 41;

[0032] After the screw 42 starts to rotate, the moving block 431 starts to slide on the surface of the screw 42. When the cylindrical gear 433 and the rack on the top of the gear bar 3 mesh with each other, the cylindrical gear 433 drives the rotating column 432 to start rotating, thereby driving the fixed component 5 to flip. When the moving block 431 reaches the guide plate 2 45, the limiting column 436 is guided by the guide plate 2 45, so that the limiting column 436 slides in the limiting slide groove 437, thereby causing the cylindrical gear 433 to deviate from its original position and enter the side of the gear bar 3 without the rack. At this time, the screw 42 starts to flip, causing the moving block 431 to return to its original position and return to its original position through the guide plate 1 44, waiting for the next operation; when a spin-drying operation is required, there is no need to let the moving block 431 reach the guide plate 2 45 for guidance, so that it can continuously pass through the side of the gear bar 3 with the rack to spin out the water, which is convenient for subsequent stacking and collection.

[0033] like Figure 6 and Figure 8 As shown, a fixing assembly 5 is provided at one end of the flip assembly 4, and the fixing assembly 5 includes a connecting column 51, one end of the connecting column 51 is fixedly connected to the other end of the rotating column 432, and the other end of the connecting column 51 is fixedly connected to a square frame 52, and the left and right walls of the square frame 52 are fixedly connected to connecting plates 53, and one end of the connecting plate 53 facing the inner side of the square frame 52 is fixedly connected to a plurality of evenly distributed springs 54, and one end of the plurality of springs 54 away from the connecting plate 53 is fixedly connected to a limiting plate 55, and a circuit board 56 is slidably connected between the two limiting plates 55, and a rubber pad is provided on the contact surface between the limiting plate 55 and the circuit board 56, and the rubber pad can increase the friction between the limiting plate 55 and the circuit board 56, so as to facilitate the limiting plate 55 to better clamp the circuit board 56;

[0035] like Figure 7 As shown, a cleaning component 6, a water spray component 7 and a sewage discharge component 8 are arranged inside the housing 1;

[0036] The cleaning component 6 includes a protective shell 61, the top of the protective shell 61 is fixedly connected to the top wall of the shell 1, the bottom wall of the protective shell 61 is fixedly installed with a motor 62, the output end of the motor 62 is fixedly connected to a rotating shaft 63 through a coupling, the outer surface of the rotating shaft 63 is fixedly connected to a bevel gear 64, the outer surface of the bevel gear 64 is meshed with a bevel gear 65, and the bevel gear 65 is fixedly connected to the outer surface of the screw 42, the outer surface of the rotating shaft 63 is fixedly connected to a pulley 66, and a rotating component 67 is provided on the top of the shell 1, and the rotating component 67 includes a rotating shaft 671, and the rotating shaft 671 is rotatably connected to the top of the shell 1. The second rotating shaft 671 passes through the top of the outer shell 1 and extends into the inner cavity of the protective shell 1 61. The outer surface of the second rotating shaft 671 is fixedly connected with the second pulley 672. A belt 673 is wound around the second pulley 672 and the first pulley 66. The outer surface of the second rotating shaft 671 is fixedly connected with the third bevel gear 674. The outer surface of the third bevel gear 674 is meshed with the fourth bevel gear 675. The inner surface of the fourth bevel gear 675 is fixedly connected with the third rotating shaft 676. The end of the third rotating shaft 676 away from the fourth bevel gear 675 is fixedly connected with a cleaning turntable 677. The front end of the cleaning turntable 677 is fixedly connected with a plurality of cleaning soft brushes distributed in a ring array.

[0037] After the motor 62 is started, it will drive the rotating shaft 1 63 to rotate, thereby driving the bevel gear 1 64 and the bevel gear 2 65 to rotate in turn. During the rotation of the bevel gear 2 65, the lead screw 42 will be driven to rotate. In addition, the rotating shaft 1 63 will drive the pulley 1 66 to rotate while rotating, and then drive the rotating shaft 2 671 to rotate through the belt 673. During the rotation, the rotating shaft 2 671 will drive the bevel gear 3 674 and the bevel gear 4 675 to rotate in turn, thereby driving the rotating shaft 3 676 and the cleaning turntable 677 fixedly connected thereto to rotate, thereby cleaning the surface of the circuit board 56.

[0038] like Figure 2 and Figure 4As shown, the water spray assembly 7 includes a water tank 71 and a water pump 72. The bottom of the water tank 71 is fixedly connected to the bottom wall of the housing 1. The water pump 72 is fixedly installed on the bottom wall of the water tank 71.

A pipe 2 is fixedly connected between the output end of the water pump 72 and the water spray gun 73. A water inlet pipe 74 is fixedly connected to the rear end of the water tank 71, and the water inlet pipe 74 is communicated with the outside.

[0039] Water is injected into the water tank 71 through the water inlet pipe 74, and then the water pump 72 uses pipe one to pump the water inside the water tank 71 into the water spray gun 73 along pipe two, and the water is sprayed onto the cleaning soft brush of the cleaning turntable 677 through the water spray gun 73 to facilitate subsequent cleaning operations.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, the sewage discharge component 8 includes a water reservoir 81, which is opened on the top of the shell 1.

[0041] The working principle of the present invention is as follows: first, the circuit board 56 is placed between the two limiting plates 55. The two limiting plates 55 squeeze the spring 54 according to the size of the circuit board 56. When the spring 54 is squeezed to a certain extent, it begins to rebound, thereby causing the limiting plates 55 to squeeze and fix the circuit board 56; then the motor 62 is started. After the motor 62 is started, it will drive the rotating shaft 1 63 to rotate, thereby driving the bevel gear 1 64 and the bevel gear 2 65 to rotate in turn. During the rotation of the bevel gear 2 65, the lead screw 42 will be driven to rotate. After the lead screw 42 starts to rotate, the moving block 431 starts to slide on the surface of the lead screw 42. When the cylindrical gear 433 and the rack at the top of the gear bar 3 are meshed with each other, the cylindrical gear 433 drives the rotating column 432 to start rotating, thereby driving the fixed component 5 to flip over. When the moving block 431 reaches the guide plate 2 45, the limiting column 436 is guided by the guide plate 2 45, thereby causing the limiting The column 436 slides in the limiting slide groove 437, thereby causing the cylindrical gear 433 to deviate from its original position and enter the side of the gear bar 3 without the rack. At this time, the screw 42 begins to flip, causing the moving block 431 to return to its original position and return to its original position through the guide plate 1 44, waiting for the next operation; when a spin-drying operation is required, there is no need for the moving block 431 to reach the guide plate 2 45 for guidance, so that it can continuously pass through the side of the gear bar 3 with the rack to spin out the water, which is convenient for subsequent stacking and collection; when cleaning is required, the rotating shaft 1 63 rotates while driving the pulley 1 66 to rotate, and then drives the rotating shaft 2 671 to rotate through the belt 673. During the rotation process, the rotating shaft 2 671 will successively drive the bevel gear 3 674 and the bevel gear 4 675 to rotate, thereby driving the rotating shaft 3 676 and the cleaning turntable 677 fixedly connected to it to rotate, thereby cleaning the surface of the circuit board 56.
