The slow drainage component 5 is located at the top of the drainage pipe 62. A connecting pipe 61 is fixedly installed between the top end of the drainage pipe 62 and the water storage tray 24;

[0049] The slow drainage assembly 5 includes a third gear 51 which is rotatably connected to the bottom end of the water storage tray 24. A toothed ring 53 is fixedly installed at the bottom end of the cleaning brush disc 43. A water retaining ring 52 is movably connected to the top end of the drain pipe 62. An up-and-down reciprocating assembly 54 is provided above the water retaining ring 52. The up-and-down reciprocating assembly 54 includes a fixing plate 541 which is fixedly installed at the top end of the drain pipe 62. A telescopic rod 543 and a first spring 544 are fixedly installed at the bottom end of the fixing plate 541. The bottom ends of the telescopic rod 543 and the first spring 544 are fixedly installed on the water retaining ring 52. A protrusion 545 is fixedly installed at the top end of the water retaining ring 52. A roller 542 is rotatably connected to the bottom end of the third gear 51. The roller 542 is located above the protrusion 545. The protrusion 545 is located above the fixing plate 541;

[0050] A transport assembly 8 is provided at the top end of the machine housing 1. The transport assembly 8 includes a support frame 81 which is slidably connected to the front and rear sides of the top end of the machine housing 1. Driving wheels 82 are rotatably connected to both the left and right ends of the support frame 81. A third motor 83 is fixedly installed at the bottom end of the support frame 81. The third motor 83 is in transmission connection with the driving wheels 82. A transport belt 84 is in transmission connection with the surface of the driving wheels 82. A card slot ring is formed at the bottom end of the outer wall of the transport belt 84. A positioning plate 85 is fixedly installed at the bottom end of the support frame 81. The positioning plate 85 is slidably connected to the side walls of the left and right ends of the machine housing 1. The bottom end of the support frame 81 is fixedly connected to the first rack 23;

[0051] A water spray pipe 9 is fixedly installed at the top end of the inner cavity of the machine housing 1. The water outlet direction of the water spray pipe 9 is downward. The water spray pipe 9 is located above the transport assembly 8. The transport assembly 8 is located above the cleaning brush disc 43.

[0052] In this embodiment, the motor 21 is started, and the motor 21 can drive the bidirectional lead screw 22 to rotate. Through the two opposite direction threads set on the bidirectional lead screw 22, the front and rear transport components 8 can move in opposite directions. When cleaning the circuit board 99, the spacing value of the retaining ring grooves at the bottom ends of the two transport belts 84 is adjusted to make the spacing value equal to the width of the circuit board 99, so that circuit boards 99 of different widths can be cleaned. When cleaning, the water spray pipe 9 sprays cleaning liquid onto the cleaning brush plate 43, so that the cleaning brush plate 43 carries the cleaning liquid to contact the circuit board 99 for cleaning. At the same time, the transport belt 84 will rotate to The circuit board 99 is transported from left to right (similar to the clamping belt conveyor in the prior art); when the cleaning is completed and the machine is ready to be shut down, the circuit board 99 has been cleaned and moved away from the equipment, and the bidirectional lead screw 22 drives the transport assembly 8 to move toward the center of the casing 1. When the rack 1 23 is meshed with the gear 1 32, the rack 1 23 drives the gear 1 32 to rotate, and then the gear 1 32 is meshed with the meshing sleeve 33 to drive the lower plate 31 to move downward. There are two gears 1 32 and two meshing sleeves 33, and the threads on the two gears 1 32 and the two meshing sleeves 33 rotate in opposite directions to ensure that the lower plate 31 can move downward smoothly. When moving downward, the rotating shaft 42 and the motor 2 41 on the downward plate 31 can be driven to move downward, while the gear 3 51 and the connecting pipe 61 have no contact with the downward plate 31. The rotating shaft 42 moves downward to drive the gear ring 53 to mesh with the gear 3 51, and the cleaning brush plate 43 drives the roller 542 to rotate around the axis of the gear 3 51. When the roller 542 contacts the top of the protrusion 545, the protrusion 545 can be pressed downward, thereby driving the water retaining ring 52 to be pressed downward, so that the water retaining ring 52 and the connecting pipe 61 are staggered. At this time, the cleaning liquid in the water storage tray 24 flows into the top of the drain pipe 62 through the connecting pipe 61, and flows into the drain pipe through the gap in the middle of the water retaining ring 52. 62, since the fixed plate 541 is located above the water retaining ring 52, the space above the water retaining ring 52 can be sealed to prevent the cleaning liquid from flowing out through the top of the drain pipe 62 when the cleaning liquid is discharged. As the gear three 51 rotates, when the protrusion 545 is offset from the roller 542, the spring one 544 in a stretched state can pull the water retaining ring 52 up and reset it to block the connecting pipe 61, stopping the discharge of the cleaning liquid, and then realizing intermittent drainage and water shut-off of the connecting pipe 61 as the gear three 51 continues to rotate, slowing down the drainage speed of the connecting pipe 61, and realizing automatic and slow discharge of the cleaning liquid in the water storage tray 24.

[0053] Embodiment 2: Figures 3 to 6As shown in the figure, the present invention provides an electroplating cleaning machine for circuit board production. The drainage assembly 6 further includes a water outlet pipe 63. The water outlet pipe 63 is fixedly installed on the side wall of the drainage pipe 62 and penetrates through the side wall of the machine housing 1. A lifting plate 64 is slidably connected to the inner cavity of the drainage pipe 62. A second spring 65 is fixedly installed at the bottom end of the lifting plate 64. An air pipe 66 is fixedly installed at the bottom end of the drainage pipe 62. A locking assembly 7 is provided in the inner cavity of the rotating shaft 42. The locking assembly 7 includes a connecting shaft 71. The connecting shaft 71 is fixedly installed at the bottom end of the rotating shaft 42 and is inserted into the top end of the inner cavity of the cleaning brush disc 43. A snap ring 72 is formed at the bottom end of the connecting shaft 71. A positioning piece 73 is fixedly installed inside the rotating shaft 42. A fourth gear 77 is rotatably connected to the top end of the positioning piece 73. A lock catch 76 is fixedly installed at the top end of the fourth gear 77. A lifting shaft 74 is slidably connected to the inner cavity of the rotating shaft 42. A second rack 75 is fixedly installed at the top end of the lifting shaft 74. The second rack 75 meshes with the fourth gear 77. The top end of the air pipe 66 is rotatably connected to the bottom end of the rotating shaft 42.

[0054] In this embodiment, by providing a lifting plate 64 that can move up and down inside the drainage pipe 62, when discharging the cleaning liquid, due to the elasticity of the second spring 65, the cleaning liquid will first accumulate on the lifting plate 64. When the weight of the cleaning liquid and the lifting plate 64 is greater than the elastic force of the second spring 65, the lifting plate 64 moves downward, causing the water outlet pipe 63 to be located above the lifting plate 64. Open the drainage valve connected to the end of the water outlet pipe 63 extending out of the machine housing 1, and the cleaning liquid is discharged through the water outlet pipe 63. When the drainage valve of the water outlet pipe 63 is not opened, the downward movement of the lifting plate 64 can press the air below the lifting plate 64 into the air pipe 66, pushing the lifting shaft 74 inside the rotating shaft 42 upward. Rectangular grooves are provided on the left and right sides of the lifting shaft 74, and the rectangular grooves are in contact with the positioning piece 73. The lifting shaft 74 is limited by the positioning piece 73 so that the lifting shaft 74 can only move up and down and cannot rotate, driving the second rack 75 upward. Through the meshing of the second rack 75 and the fourth gear 77, the fourth gear 77 and the lock catch 76 can be driven to rotate, so that the top end of the lock catch 76 leaves the snap ring 72. At this time, the cleaning brush disc 43 and the rotating shaft 42 are separated. At this time, if a new cleaning brush disc 43 needs to be replaced, the cleaning brush disc 43 can be directly taken out upward to replace it with a new one. During the replacement process, due to the slow discharge of the cleaning liquid by the slow discharge assembly 5, the water storage tray 24 is still in the process of draining water, and the lock catch 76 is in the unlocked state. When the drainage is completed, the lifting plate 64 moves upward to reset, and the lock catch 76 automatically locks the snap ring 72 to fix the cleaning brush disc 43. And within the time range from removing the cleaning brush disc 43 to installing a new cleaning brush disc 43, the cleaning brush disc 43 stops rotating. After installation, the cleaning brush disc 43 is driven to rotate again to continue draining water.

[0055] Embodiment Three: As Figure 3 、 Figure 4 、 Figure 8 andFigure 9 As shown in the figure, the present invention provides an electroplating cleaning machine for circuit board production. The cleaning component 4 further includes a second motor 41, a rotating shaft 42 and a synchronization component 44. The rotating shaft 42 is rotatably connected to the bottom end of the water storage tray 24. The cleaning brush disc 43 is located above the rotating shaft 42. The second motor 41 is fixedly installed at the bottom end of the downward moving plate 31. The synchronization component 44 includes a second gear 441. The second gear 441 is fixedly sleeved on the output end of the second motor 41 and the bottom end of the rotating shaft 42. A transmission wheel 442 is fixedly sleeved on the bottom end of the rotating shaft 42. A transmission belt 443 is drivingly connected to the surface of the transmission wheel 442.

[0056] In this embodiment, the downward moving plate 31 is arranged to be able to drive the cleaning brush disc 43 to move up and down. When the cleaning liquid is discharged, the cleaning brush disc 43 can be immersed in the cleaning liquid in the water storage tray 24. By rotating the cleaning brush disc 43, the dirt located inside the cleaning brush disc 43 can be thrown out in the cleaning liquid, realizing the cleaning of the cleaning brush disc 43. The setting of slowly discharging the cleaning liquid in the water storage tray 24 can ensure that during the cleaning process of the cleaning brush disc 43, the cleaning brush disc 43 is always immersed in the cleaning liquid, avoiding the situation that when the cleaning of the cleaning brush disc 43 is not completed, the immersion liquid has been completely discharged and the thorough cleaning of the cleaning brush disc 43 cannot be achieved. The setting of the second gear 441 provides space for the connection between the air pipe 66 and the rotating shaft 42. The setting of the transmission wheel 442 and the transmission belt 443 can realize the simultaneous rotation of multiple cleaning brush discs 43.

[0057] The working process is as follows:

[0058] When in use, start the first motor 21. The first motor 21 drives the bidirectional lead screw 22 to rotate. Since the front and rear ends at the center of the bidirectional lead screw 22 are respectively provided with two threads with opposite rotation directions, when the bidirectional lead screw 22 rotates, it can drive the first rack 23 and the transportation component 8 to move back and forth, so that the distance value between the card slot rings at the bottom ends of the two transportation belts 84 is equal to the width of the circuit board 99. Start the water spraying pipe 9, and spray the cleaning liquid onto the cleaning brush disc 43 through the water spraying pipe 9;

[0059] Place the circuit board 99 into the two card slot rings on the left side of the device. The third motor 83 drives the driving wheel 82 and the third motor 83 to rotate, so that the transportation belt 84 transports the circuit board 99 from left to right;

[0060] The second motor 41 is started, and the second motor 41 drives the second gear 441 to rotate, and then the second gear 441 drives the transmission wheel 442 to rotate, and the transmission belt 443 drives multiple transmission wheels 442, so that multiple transmission wheels 442 can simultaneously drive the cleaning brush plate 43 to rotate through the rotating shaft 42. When the circuit board 99 is transported to the cleaning brush plate 43, the rotating cleaning brush plate 43 contacts the circuit board 99, thereby cleaning the circuit board 99;

[0061] When the cleaning device is shut down, there is no circuit board 99 between the slot rings, and the bidirectional lead screw 22 rotates in the opposite direction, driving the rack 23 to move toward the center of the water storage tray 24 through the transport component 8. When the rack 23 is meshed with the gear 32, the rack 23 drives the gear 32 to rotate, and then the meshing of the gear 32 and the engagement sleeve 33 can drive the lower plate 31 to move downward. When the lower plate 31 moves downward, it can drive the rotating shaft 42 to move downward, and then drive the cleaning brush plate 43 to move down and be stored in the water storage tray 24. When the cleaning brush plate 43 is completely stored in the water storage tray 24, the gear ring 53 is meshed with the gear three 51. At this time, the rotation of the cleaning brush plate 43 can drive the roller 542 to rotate around the axis of the gear three 51. As the gear 3 51 rotates, when the protrusion 545 and the roller 542 come into contact with the top of the projection 545, the projection 545 can be pressed down, thereby driving the water retaining ring 52 to be pressed down, so that the water retaining ring 52 and the connecting pipe 61 are staggered. At this time, the cleaning liquid in the water storage pan 24 flows into the top of the drain pipe 62 through the connecting pipe 61, and flows into the drain pipe 62 through the gap in the middle of the water retaining ring 52. As the gear 3 51 rotates, when the projection 545 and the roller 542 are staggered, the spring 1 544 in the stretched state can pull up the water retaining ring 52 to reset and block the connecting pipe 61, stopping the discharge of the cleaning liquid, and then realizing that as the gear 3 51 rotates continuously, the drainage of the connecting pipe 61 can be realized intermittently and the water is turned off, slowing down the drainage speed of the connecting pipe 61.

[0062] During drainage, the cleaning brush plate 43 rotates continuously. Since the cleaning brush plate 43 is completely immersed in the cleaning liquid in the water storage tray 24, the cleaning brush plate 43 rotates in the cleaning liquid, and the dirt accumulated in the cleaning brush plate 43 is thrown out of the cleaning brush plate 43, thereby cleaning the cleaning brush plate 43.

[0063] The cleaning liquid that enters the drain pipe 62 through the connecting pipe 61 will fall into the lifting plate 64. As the cleaning liquid on the lifting plate 64 continues to increase, the gravity of the lifting plate 64 and the cleaning liquid will overcome the elastic force of the spring 2 65, so that the lifting plate 64 moves downward, so that the lifting plate 64 is located below the outlet pipe 63, and the drain valve at the right end of the outlet pipe 63 is opened. At this time, the cleaning liquid on the lifting plate 64 is directly discharged from the device through the outlet pipe 63;

[0064] During the downward movement of the lifting plate 64, the air located below the lifting plate 64 in the drain pipe 62 can be pushed into the air pipe 66, and then enter the bottom end of the rotating shaft 42, pushing up the lifting shaft 74 in the rotating shaft 42, driving the second rack 75 to move upward. Through the meshing of the second rack 75 and the fourth gear 77, the fourth gear 77 and the lock 76 can be driven to rotate, causing the top end of the lock 76 to leave the buckle 72. At this time, the cleaning brush disc 43 and the rotating shaft 42 are separated;

[0065] If the rotating shaft 42 is worn and needs to be replaced, when the lower moving plate 31 drives the cleaning brush disc 43 to move downward, during the process of removing and installing the cleaning brush disc 43, stop the motor two 41 from driving the rotating shaft 42 to rotate. At this time, directly pull the cleaning brush disc 43 upward to remove the cleaning brush disc 43, and then insert the bottom end of the new cleaning brush disc 43 into the top end of the rotating shaft 42. Since the connecting shaft 71 and the top end of the rotating shaft 42 are in a regular hexagon shape, it can ensure that when the rotating shaft 42 rotates, it can drive the cleaning brush disc 43 to rotate. When the cleaning liquid in the drain pipe 62 is discharged until the weight of the cleaning liquid and the lifting plate 64 cannot overcome the elastic force of the second spring 65, the lifting plate 64 moves upward to reset, and then the air in the air pipe 66 is drawn back into the drain pipe 62. At this time, the lifting shaft 74 falls under the action of gravity, causing the lock 76 to rotate in the reverse direction and buckle on the buckle 72 to lock the connecting shaft 71;

[0066] If the rotating shaft 42 is not worn and does not need to be replaced, when the lower moving plate 31 moves downward to drive the rotating shaft 42 and the cleaning brush disc 43 to move downward, the motor two 41 drives the cleaning brush disc 43 to rotate for cleaning without the need for operation. Wait until the cleaning liquid in the drain pipe 62 is discharged until the weight of the cleaning liquid and the lifting plate 64 cannot overcome the elastic force of the second spring 65, the lifting plate 64 moves upward to reset, and then the air in the air pipe 66 is drawn back into the drain pipe 62. At this time, the lifting shaft 74 falls under the action of gravity, causing the lock 76 to rotate in the reverse direction and buckle on the buckle 72 to lock the connecting shaft 71 again.
