Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and specifically to a circuit board ink cleaning device and a cleaning method thereof. Background Art

[0002] A circuit board is a basic electronic component used to build and arrange circuit components with circuit diagrams. It consists of multiple printed circuit boards, including one or more metal layers, plastic layers, insulating layers, and control layers. These layers are all perforated and plated with conductors for connection and conduction. To ensure the normal operation of the circuit, all elements on the circuit board must be correctly assembled in their positions to meet the circuit requirements. The main function of the circuit board is to carry and perform the functions of the circuit system. It can provide fixed electrical connection points and effectively isolate the influence of continuity. In addition, the circuit board can also reduce the line length and interference, thereby eliminating interference signals and improving the noise resistance of the circuit. It can also greatly simplify the circuit wiring and component layout processes and reduce the design cost.

[0003] During the production process of circuit boards, during the printing of circuit boards, ink may be coated by inkjet or screen printing. If the inkjet pressure, speed, or angle is inappropriate, the ink may splash onto the surface of the circuit board, especially in smaller component or circuit areas, and the finished circuit board needs to be cleaned in a timely manner.

[0004] In the prior art, most circuit boards are densely placed in a material frame, and then multiple groups of circuit boards are rinsed through the water-based cleaning technology inside the cleaning device. By spraying water flow and cleaning agents, impurities such as ink and dirt on the surface of the circuit board are cleaned. First, the cleaning agent is sprayed onto the surface of the circuit board. The cleaning agent dissolves and detaches the ink and dirt on the surface of the circuit board, and then the surface of the circuit board is further cleaned by the water flow. However, when spraying the water flow and the cleaning agent, the outer circuit boards are very likely to block the inner circuit boards, resulting in large differences in the cleaning effects of each group of circuit boards. At the same time, there will also be large differences in the cleaning effects of both sides of each group of circuit boards, reducing the cleaning efficiency. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a circuit board ink cleaning device and a cleaning method thereof to solve the technical problems in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A circuit board ink cleaning device includes a device main body, a cleaning chamber, a placement board, and a placement seat. The cleaning chamber is provided at the upper end of the device main body. The number of the placement boards and the placement seats are both multiple groups, and multiple groups of placement boards and multiple groups of placement seats are movably connected; Multiple groups of connecting rods are respectively arranged between multiple groups of the placement plates, and the upper ends of multiple groups of placement plates are all inclined. Symmetrical reserved grooves are respectively opened at the bottoms of multiple groups of placement plates, and the inner walls of multiple groups of reserved grooves are respectively movably connected with the outer walls of multiple groups of placement seats. Connecting columns are respectively arranged between multiple groups of placement seats; A first driving motor is installed inside the device main body. A first driving shaft is installed at the output end of the first driving motor. Two conveying rollers are movably installed at both ends of the device main body, and a synchronous belt is arranged between the two conveying rollers. A synchronous belt is arranged between one conveying roller and the first driving shaft. Two conveyor belts are annularly arranged on the outer walls of the two conveying rollers, and the two conveyor belts are respectively movably connected with multiple groups of placement plates; A first liquid outlet plate is movably installed inside the cleaning bin. A first liquid inlet pipe is installed at the liquid inlet of the first liquid outlet plate, and the first liquid inlet pipe extends to the outer wall of the cleaning bin and is externally connected to a cleaning agent tank at one end. Fixed columns are symmetrically installed on the outer wall of the first liquid outlet plate. Two limiting cylinders are symmetrically installed on the inner wall of the cleaning bin, and the inner walls of multiple groups of limiting cylinders are respectively threadedly connected with the outer walls of multiple groups of fixed columns. Multiple contraction cylinders are symmetrically installed on the inner wall of the cleaning bin, and multiple groups of contraction cylinders are respectively connected by multiple groups of synchronous belts. Multiple groups of limiting cylinders and multiple groups of contraction cylinders are respectively connected by multiple groups of synchronous belts. Telescopic columns are movably installed on the inner walls of multiple groups of contraction cylinders. Push plates are installed at one ends of multiple groups of telescopic columns, and the outer walls of multiple groups of push plates are respectively movably connected with the outer walls of multiple groups of placement seats; A second driving motor is installed inside the device main body. A second driving shaft is installed at the output end of the second driving motor. Two first limiting shafts are movably installed inside the cleaning bin, and a synchronous belt is arranged between the two first limiting shafts. The second driving shaft is movably connected with the two first limiting shafts. Reciprocating thread grooves are respectively opened on the outer walls of the two first limiting shafts, and the outer walls of the two first limiting shafts are respectively threadedly connected with the inner wall of the first liquid outlet plate.

[0007] By adopting the above technical scheme, the bottoms of multiple groups of circuit boards are respectively placed on the upper ends of multiple groups of placement seats, and the upper ends of multiple groups of circuit boards are respectively movably connected with multiple groups of placement plates. After the first liquid outlet plate sprays the cleaning agent onto one outer wall of the circuit board, the push plate displaces, pushing the two placement seats to displace, thereby driving multiple groups of placement seats to displace, so that multiple groups of circuit boards are turned over. The first liquid outlet plate performs a reciprocating displacement movement, and the first liquid outlet plate continuously sprays the cleaning agent. The first liquid outlet plate sprays the cleaning agent onto the other outer wall of the circuit board, and the cleaning agent dissolves and falls off the ink and dirt on both outer walls of the circuit board, improving the cleaning effect on the surfaces of multiple groups of circuit boards.

[0008] The present invention is further configured such that multiple convex blocks are installed on the outer walls of the two conveyor belts, and multiple groups of convex blocks correspond to each other. Installation plates are respectively arranged on the outer walls of the two placement plates. Grooves are respectively opened at the bottoms of the two installation plates, and the two grooves are respectively engaged with multiple groups of convex blocks.

[0009] Preferably, the grooves at the bottom ends of the two groups of mounting plates are respectively engaged with the two groups of bumps opposite to the upper ends of the two groups of conveyor belts. When the two groups of conveyor belts operate, they drive multiple groups of placing plates, multiple groups of placing seats, and multiple groups of circuit boards to move.

[0010] The present invention is further configured such that a conveying gear is installed at one end of a group of conveying rollers, a transmission shaft is movably installed inside the device main body, a transmission gear is installed at one end of the transmission shaft, and the transmission gear is meshed and connected with the conveying gear. The diameter of the conveying gear is larger than the diameter of the transmission gear. An activity shaft is movably installed inside the device main body, and a synchronous belt is provided between the activity shaft and the transmission shaft for connection.

[0011] Preferably, when a group of conveying rollers rotate, they drive the conveying gear to rotate. The conveying gear is meshed and connected with the transmission gear, so the transmission gear rotates. And since the diameter of the transmission gear is smaller than the diameter of the conveying gear, the rotation speed of the transmission gear is greater than the rotation speed of the conveying gear, thereby driving the transmission shaft to rotate. The transmission shaft and the activity shaft are connected by a synchronous belt, and the activity shaft rotates.

[0012] The present invention is further configured such that a linkage shaft is movably installed on the inner wall of the cleaning bin, and a synchronous belt is provided between the linkage shaft and the activity shaft for connection.

A limiting bevel gear is installed at one end of a group of limiting columns, and the limiting bevel gear is meshed and connected with the linkage bevel gear. Multiple baffles are movably installed on the inner wall of the cleaning bin. Reciprocating thread grooves are formed on the outer walls of the multiple limiting columns, and the outer walls of the multiple limiting columns are respectively threadedly connected with the inner walls of the multiple baffles.

[0013] Preferably, the activity shaft rotates, and since the activity shaft and the linkage shaft are connected by a synchronous belt, the linkage shaft rotates, thereby driving the linkage bevel gear to rotate. The linkage bevel gear is meshed and connected with the limiting bevel gear, so the limiting bevel gear rotates, thereby driving a group of limiting columns to rotate. The multiple limiting columns are respectively connected by multiple synchronous belts, so the multiple limiting columns rotate synchronously. The outer walls of the multiple limiting columns are respectively threadedly connected with the inner walls of the multiple baffles, so the multiple baffles move, and since the thread grooves on the outer walls of the multiple limiting columns are reciprocating thread grooves, the multiple baffles move reciprocally.

[0014] The present invention is further configured such that multiple convex plates are respectively provided and connected between the multiple placing plates, and the outer walls of the multiple convex plates are respectively connected with the inner walls of the multiple reserved grooves. Symmetrical limiting grooves are formed at the bottom ends of the multiple placing seats, and the inner walls of the multiple limiting grooves are respectively movably connected with the outer walls of the multiple convex plates.

[0015] Preferably, the push plate pushes the two groups of placement seats to move, thereby driving the multiple groups of placement seats to move, so that the multiple groups of placement seats move respectively through the multiple groups of convex plates.

[0016] The present invention is further configured that two groups of second limiting shafts are movably installed on the inner wall of the cleaning bin, and a synchronous belt is connected between the two groups of second limiting shafts. A synchronous belt is connected between one group of second limiting shafts and the second driving shaft, and a synchronous belt is connected between the other group of second limiting shafts and one group of first limiting shafts.

[0017] Preferably, when the second driving shaft rotates, it drives one group of second limiting shafts to rotate. Since a synchronous belt is connected between the two groups of second limiting shafts, the two groups of second limiting shafts rotate synchronously. The other group of second limiting shafts drives one group of first limiting shafts to rotate. Since a synchronous belt is connected between the two groups of first limiting shafts, the two groups of first limiting shafts rotate synchronously.

[0018] The present invention is further configured that a second liquid outlet plate is movably installed inside the cleaning bin. A second liquid inlet pipe is installed at the liquid inlet of the second liquid outlet plate, and the second liquid inlet pipe extends to one end of the outer wall of the cleaning bin and is externally connected to a water tank. Reciprocating thread grooves are formed on the outer walls of the two groups of second limiting shafts, and the outer walls of the two groups of second limiting shafts are respectively threadedly connected to the inner wall of the second liquid outlet plate. A collection box is installed inside the device main body. A first storage bin and a second storage bin are respectively formed inside the collection box, and the first storage bin and the second storage bin are respectively arranged below the first liquid outlet plate and the second liquid outlet plate.

[0019] Preferably, when the two groups of second limiting shafts rotate, the outer walls of the two groups of second limiting shafts are respectively threadedly connected to the inner wall of the second liquid outlet plate, so the second liquid outlet plate moves. The second liquid inlet pipe extends to one end of the outer wall of the cleaning bin and is externally connected to a water tank. The water pump in the water tank conducts the water source to the second liquid outlet plate through the second liquid inlet pipe. At the same time, as the second liquid outlet plate moves, the second liquid outlet plate sprays the water source onto the outer wall of the circuit board, and the first storage bin and the second storage bin respectively collect the sewage.

[0020] The present invention is further configured that a wind box is installed inside the device main body, and a fan is installed on the outer wall of one end where the second driving shaft extends into the wind box. An air inlet pipe is installed at the air inlet of the wind box, an air outlet pipe is installed at the air outlet of the wind box, and an air outlet plate is installed on the outer wall of the cleaning bin, and the air inlet of the air outlet plate is connected to one end of the air outlet pipe.

[0021] Preferably, when the second driving shaft rotates, it drives the fan to rotate, so that an air flow is generated inside the wind box. The air flow enters the wind box through the air inlet pipe, and the air flow is transmitted from the air outlet pipe to the air outlet plate.

[0022] The present invention is further configured such that a flow guide plate is installed on the outer wall of one end of the collection box, and the flow guide plate is inclined. The flow guide plate extends to the outer wall of the cleaning chamber, and the air outlet of the air outlet plate faces the flow guide plate. Limit rods are installed at the bottom ends of multiple push plates, and the outer walls of multiple telescopic columns are respectively threadedly connected to the inner walls of multiple contraction cylinders.

[0023] Preferably, air flows from the air outlet pipe to the air outlet plate, and the air outlet of the air outlet plate faces multiple placement plates, thereby drying the surfaces of multiple circuit boards. The residual water sources on the surfaces of multiple circuit boards fall onto the upper end of the flow guide plate, and the residual water sources flow into the second storage chamber through the flow guide plate.

Two groups of grooves are respectively engaged with two groups of corresponding convex blocks. The first driving motor is started to drive the operation of two groups of conveyor belts, thereby driving the displacement of multiple placement seats, multiple placement plates, and multiple circuit boards. Multiple circuit boards respectively stay under the first liquid outlet plate, under the second liquid outlet plate, and at the upper end of the flow guide plate; S: Cleaning operation of multiple circuit boards: When multiple circuit boards stay under the first liquid outlet plate, the first driving motor is turned off, and the second driving motor is started to drive the first liquid outlet plate to perform reciprocating displacement. The first liquid outlet plate sprays a cleaning agent to clean the outer wall of one side of the circuit board, and the push plate pushes the placement seat to perform displacement, thereby driving the circuit board to turn over, so that the cleaning agent is sprayed onto the outer wall of the other side of the circuit board.

The second liquid outlet plate sprays water to flush the outer wall of one side of the circuit board, and the push plate pushes the placement seat to perform displacement, thereby driving the circuit board to turn over, so that the water is sprayed onto the outer wall of the other side of the circuit board. The water flushes the residual ink and dirt on the surface of the circuit board into the second storage chamber; S: Drying operation of multiple circuit boards: When multiple circuit boards stay at the upper end of the flow guide plate, the first driving motor is turned off, and the second driving motor is started. The air outlet of the air outlet plate faces multiple placement plates, thereby drying the surfaces of multiple circuit boards. The residual water sources on the surfaces of multiple circuit boards fall onto the upper end of the flow guide plate, and the residual water sources flow into the second storage chamber through the flow guide plate.

[0025] In summary, the present invention mainly has the following beneficial effects: The present invention solves the problem of large differences in the cleaning effects of each group of circuit boards by providing a placement plate, a placement seat, a first liquid outlet plate, and a push plate. The bottoms of multiple groups of circuit boards are respectively placed on the upper ends of multiple groups of placement seats, and the upper ends of multiple groups of circuit boards are respectively movably connected to multiple groups of placement plates. After the first liquid outlet plate sprays the cleaning agent onto one outer wall of the circuit board, the push plate moves, driving two placement seats to move, thereby driving multiple groups of placement seats to move, causing multiple groups of circuit boards to turn over. The first liquid outlet plate performs a reciprocating displacement movement, continuously spraying the cleaning agent. The first liquid outlet plate sprays the cleaning agent onto the other outer wall of the circuit board, and the cleaning agent dissolves and removes the ink and dirt on both outer walls of the circuit board, improving the cleaning effect on the surfaces of multiple groups of circuit boards.

[0026] The present invention solves the problem of large differences in the cleaning effects of each group of circuit boards by providing a first liquid outlet plate, a second liquid outlet plate, and an air outlet plate. The second drive shaft rotates, driving the first liquid outlet plate and the second liquid outlet plate to reciprocate. At the same time, an air flow is generated inside the air box. The first liquid outlet plate moves and sprays the cleaning agent, and the cleaning agent dissolves the ink and dirt on both outer walls of the circuit board. The second liquid outlet plate moves and sprays water, and the water flushes both outer walls of multiple groups of circuit boards, causing the remaining ink and dirt on the outer walls of multiple groups of circuit boards to fall off. The air flow is conducted to the air outlet plate, and the air outlet plate dries multiple groups of circuit boards, causing the remaining water on the surfaces of multiple groups of circuit boards to evaporate or fall off onto the upper end of the diversion plate. Multiple groups of circuit boards are simultaneously sprayed with the cleaning agent, surface-cleaned, and surface-dried, improving the cleaning efficiency of multiple groups of circuit boards and further improving the processing efficiency of the circuit boards.

[0030] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0031] A circuit board ink cleaning device, please refer to Figure 1 - Figure 13 , which includes a device main body 1, a cleaning bin 2, a placement plate 17 and a placement seat 23. A cleaning bin 2 is provided at the upper end of the device main body 1. The number of the placement plates 17 and the placement seats 23 are both multiple groups, and the multiple groups of placement plates 17 and the multiple groups of placement seats 23 are movably connected; Multiple connecting rods 20 are respectively provided between the multiple groups of placement plates 17 for connection.

At the output end of the first driving motor 3, a first driving shaft 4 is installed. When the first driving motor 3 starts, it drives the first driving shaft 4 to rotate. At both ends of the device main body 1, two groups of conveying rollers 5 are movably installed, and a synchronous belt is connected between the two groups of conveying rollers 5. A synchronous belt is connected between one group of conveying rollers 5 and the first driving shaft 4. The first driving shaft 4 drives one group of conveying rollers 5 to rotate, so the two groups of conveying rollers 5 rotate synchronously. Two groups of conveyor belts 6 are annularly arranged on the outer walls of the two groups of conveying rollers 5. The two groups of conveyor belts 6 operate, and the two groups of conveyor belts 6 are respectively movably connected to multiple placement plates 17 to drive the multiple placement plates 17 to displace; Inside the cleaning chamber 2, a first liquid outlet plate 37 is movably installed. At the liquid inlet of the first liquid outlet plate 37, a first liquid inlet pipe 39 is installed, and the first liquid inlet pipe 39 extends to one end of the outer wall of the cleaning chamber 2 and is externally connected to a cleaning agent tank. The water pump in the cleaning agent tank conducts the cleaning agent through the first liquid inlet pipe 39 to the first liquid outlet plate 37. The first liquid outlet plate 37 sprays the cleaning agent onto the outer wall of the circuit board. The cleaning agent dissolves the ink and dirt on the outer wall of the circuit board. Fixed columns 38 are symmetrically installed on the outer wall of the first liquid outlet plate 37. Two groups of limiting cylinders 43 are symmetrically installed on the inner wall of the cleaning chamber 2, and the inner walls of the multiple limiting cylinders 43 are respectively threadedly connected to the outer walls of the multiple fixed columns 38. Multiple retractable cylinders 44 are symmetrically installed on the inner wall of the cleaning chamber 2, and the multiple retractable cylinders 44 are respectively connected by multiple synchronous belts. The multiple limiting cylinders 43 and the multiple retractable cylinders 44 are respectively connected by multiple synchronous belts. Telescopic columns 45 are movably installed on the inner walls of the multiple retractable cylinders 44. At one end of each of the multiple telescopic columns 45, a push plate 46 is installed, and the outer walls of the multiple push plates 46 are respectively movably connected to the outer walls of the multiple placement seats 23. The two fixed columns 38 respectively move into the two limiting cylinders 43, and the outer wall of the fixed column 38 is threadedly connected to the inner wall of the limiting cylinder 43. Therefore, the two limiting cylinders 43 rotate, and the two limiting cylinders 43 and the two retractable cylinders 44 are connected by synchronous belts respectively. Therefore, the two retractable cylinders 44 rotate. The multiple retractable cylinders 44 are respectively connected by synchronous belts. Therefore, the multiple retractable cylinders 44 rotate synchronously, thereby driving the multiple telescopic columns 45 to displace, and further driving the multiple push plates 46 to displace.

At the output end of the second driving motor 30, a second driving shaft 31 is installed. Two groups of first limiting shafts 36 are movably installed inside the cleaning chamber 2, and a synchronous belt is connected between the two groups of first limiting shafts 36.

Reciprocating thread grooves are formed on the outer walls of the two groups of first limiting shafts 36, and the outer walls of the two groups of first limiting shafts 36 are respectively threadedly connected to the inner wall of the first liquid outlet plate 37. When the second driving motor 30 starts, it drives the second driving shaft 31 to rotate, thereby driving the two groups of first limiting shafts 36 to displace, and further driving the first liquid outlet plate 37 to displace.

[0032] Please refer to Figure 2 - Figure 12 As shown in Figure 2 - Figure 12 , multiple sets of bumps 7 are installed on the outer walls of both groups of conveyor belts 6, and the multiple sets of bumps 7 correspond to each other.

The diameter of the conveying gear 8 is larger than that of the transmission gear 10. A movable shaft 11 is movably installed inside the device main body 1, and a synchronous belt is provided between the movable shaft 11 and the transmission shaft 9. When a set of conveying rollers 5 rotates, it drives the conveying gear 8 to rotate. The conveying gear 8 is meshed with the transmission gear 10, so the transmission gear 10 rotates. And since the diameter of the transmission gear 10 is smaller than that of the conveying gear 8, the rotation speed of the transmission gear 10 is greater than that of the conveying gear 8, thus driving the transmission shaft 9 to rotate. The transmission shaft 9 and the movable shaft 11 are connected by a synchronous belt, and the movable shaft 11 rotates.

When the movable shaft 11 rotates, and the movable shaft 11 and the linkage shaft 12 are connected by a synchronous belt, so the linkage shaft 12 rotates, thereby driving the linkage bevel gear 13 to rotate. The linkage bevel gear 13 is meshed with the limit bevel gear 15, so the limit bevel gear 15 rotates, thereby driving a set of limit posts 14 to rotate. The multiple sets of limit posts 14 are respectively connected by multiple sets of synchronous belts, so the multiple sets of limit posts 14 rotate synchronously. The outer walls of the multiple sets of limit posts 14 are respectively threadedly connected with the inner walls of the multiple sets of baffles 16, so the multiple sets of baffles 16 move, and since the thread grooves on the outer walls of the multiple sets of limit posts 14 are reciprocating thread grooves, the multiple sets of baffles 16 move reciprocally.

[0035] Please refer to Figure 2 - Figure 13 , between multiple groups of placement plates 17, multiple groups of convex plates 19 are respectively connected, and the outer walls of multiple groups of convex plates 19 are respectively connected to the inner walls of multiple groups of reserved grooves 18. Symmetrically arranged limiting grooves 24 are respectively opened at the bottoms of multiple groups of placement seats 23, and the inner walls of multiple groups of limiting grooves 24 are respectively movably connected to the outer walls of multiple groups of convex plates 19.

When the second driving shaft 31 rotates, it drives one group of second limiting shafts 40 to rotate, and a synchronous belt is connected between the two groups of second limiting shafts 40, so the two groups of second limiting shafts 40 rotate synchronously. The other group of second limiting shafts 40 drives one group of first limiting shafts 36 to rotate, and a synchronous belt is connected between the two groups of first limiting shafts 36, so the two groups of first limiting shafts 36 rotate synchronously.

When the two groups of second limiting shafts 40 rotate, the outer walls of the two groups of second limiting shafts 40 are both threadedly connected to the inner wall of the second liquid outlet plate 41, so the second liquid outlet plate 41 displaces. The second liquid inlet pipe 42 extends to the outer wall of the cleaning bin 2 and is externally connected to a water tank at one end. The water pump in the water tank conducts the water source through the second liquid inlet pipe 42 to the second liquid outlet plate 41. At the same time, the second liquid outlet plate 41 displaces, and the second liquid outlet plate 41 sprays the water source onto the outer wall of the circuit board. The first storage bin 27 and the second storage bin 28 respectively collect the sewage.

[0038] Please refer to Figure 2 - Figure 7A bellows 32 is installed inside the device body 1, and a second drive shaft 31 extends into the bellows 32 and a fan is installed on the outer wall at one end thereof. An air inlet duct 35 is installed at the air inlet of the bellows 32, and an air outlet duct 33 is installed at the air outlet of the bellows 32. An air outlet plate 34 is installed on the outer wall of the cleaning chamber 2, and the air inlet of the air outlet plate 34 is connected to one end of the air outlet duct 33. The second drive shaft 31 rotates, thereby driving the fan to rotate, so that airflow is generated inside the bellows 32, and the airflow enters the bellows 32 through the air inlet duct 35, and the airflow is transmitted from the air outlet duct 33 to the air outlet plate 34.

[0039] See also Figure 1 - Figure 9 A guide plate 29 is installed on the outer wall of one end of the collection box 26, and the guide plate 29 is inclined. The guide plate 29 extends to the outer wall of the cleaning bin 2, and the air outlet of the air outlet plate 34 faces the guide plate 29. Limit rods 47 are installed at the bottom ends of the multiple push plates 46, and the outer walls of the multiple telescopic columns 45 are respectively threadedly connected with the inner walls of the multiple shrink tubes 44. The air flow is transmitted from the air outlet pipe 33 to the air outlet plate 34, and the air outlet of the air outlet plate 34 faces the multiple placement plates 17, so that the surfaces of the multiple circuit boards are dried, and the residual water on the surfaces of the multiple circuit boards falls to the upper end of the guide plate 29, and the residual water flows to the inside of the second storage bin 28 through the guide plate 29.

[0040] The working principle of the present invention is as follows: when the staff uses the device to clean the ink on the surface of the circuit board, the staff places the bottom ends of multiple groups of circuit boards on the upper ends of multiple groups of placement seats 23, and the upper ends of multiple groups of circuit boards are movably connected to the outer walls of multiple groups of placement plates 17, and multiple groups of circuit boards are placed in an inclined state. Then the staff engages the grooves 22 at the bottom ends of the two groups of mounting plates 21 with the two groups of protrusions 7 opposite to the upper ends of the two groups of conveyor belts 6, and multiple groups of connecting rods 20 are provided between the multiple groups of placement plates 17, so that the multiple groups of placement plates 17 are movably connected to the two groups of conveyor belts 6. After the multiple groups of placement plates 17 are movably connected with the two groups of conveyor belts 6, the staff starts the first drive motor 3, thereby driving the first drive shaft 4 to rotate. The first drive shaft 4 is connected to a group of conveyor rollers 5 through a synchronous belt, so one group of conveyor rollers 5 rotates, and the two groups of conveyor rollers 5 are connected through a synchronous belt, so the two groups of conveyor rollers 5 rotate synchronously, thereby driving the two groups of conveyor belts 6 to operate, and then driving the multiple groups of protrusions 7 to move, and then driving the multiple groups of placement plates 17 to move, and the multiple groups of placement plates 17 move toward the entrance of the cleaning bin 2; When the two sets of conveying rollers 5 rotate, one set of conveying rollers 5 drives the conveying gear 8 to rotate. The conveying gear 8 is meshed and connected with the transmission gear 10, so the transmission gear 10 rotates. And the diameter of the transmission gear 10 is smaller than that of the conveying gear 8, so the rotation speed of the transmission gear 10 is greater than that of the conveying gear 8, thus driving the transmission shaft 9 to rotate. The transmission shaft 9 is connected with the movable shaft 11 through a synchronous belt, and the movable shaft 11 rotates. And the movable shaft 11 is connected with the linkage shaft 12 through a synchronous belt, so the linkage shaft 12 rotates, thus driving the linkage bevel gear 13 to rotate. The linkage bevel gear 13 is meshed and connected with the limit bevel gear 15, so the limit bevel gear 15 rotates, thus driving a set of limit columns 14 to rotate. The multiple sets of limit columns 14 are respectively connected by multiple sets of synchronous belts, so the multiple sets of limit columns 14 rotate synchronously. The outer walls of the multiple sets of limit columns 14 are respectively threadedly connected with the inner walls of the multiple sets of baffles 16, so the multiple sets of baffles 16 are displaced. And the thread grooves on the outer walls of the multiple sets of limit columns 14 are reciprocating thread grooves, so the multiple sets of baffles 16 are reciprocatingly displaced. The multiple sets of baffles 16 divide the inside of the cleaning chamber 2 into a cleaning room and a washing room. And the first storage bin 27 is arranged at the lower end of the cleaning room, and the second storage bin 28 is arranged at the lower end of the washing room; When the multiple sets of baffles 16 move, they respectively open the inlet of the cleaning chamber 2. The multiple sets of placing plates 17 move into the inside of the cleaning chamber 2. After the multiple sets of placing plates 17 move to the upper end of the first storage bin 27, the first driving motor 3 is turned off and the second driving motor 30 is started, thus driving the second driving shaft 31 to rotate. And the second driving shaft 31 is connected with a set of second limit shafts 40 through a synchronous belt, so a set of second limit shafts 40 rotate. The two sets of second limit shafts 40 are connected by a synchronous belt, so the two sets of second limit shafts 40 rotate synchronously. And the other set of second limit shafts 40 is connected with a set of first limit shafts 36 through a synchronous belt, so a set of first limit shafts 36 rotate. The two sets of first limit shafts 36 are connected by a synchronous belt, so the two sets of first limit shafts 36 rotate synchronously; When the two sets of first limit shafts 26 rotate, the outer walls of the two sets of first limit shafts 26 are both threadedly connected with the inner wall of the first liquid outlet plate 37, so the first liquid outlet plate 37 is displaced, thus driving the multiple sets of fixed columns 38 to be displaced. One end of the first liquid inlet pipe 39 extending to the outer wall of the cleaning chamber 2 is externally connected to a cleaning agent tank. The water pump in the cleaning agent tank conducts the cleaning agent to the first liquid outlet plate 37 through the first liquid inlet pipe 39. At the same time, as the first liquid outlet plate 37 is displaced, the first liquid outlet plate 37 sprays the cleaning agent onto the outer wall of one side of the circuit board, and the cleaning agent dissolves the ink and dirt on the outer wall of one side of the circuit board; When the first liquid outlet plate 37 moves to one end of the first limit shaft 36, two of the fixing columns 38 respectively move into the two limit cylinders 43, and the outer wall of the fixing column 38 is threadedly connected to the inner wall of the limit cylinder 43. Therefore, the two limit cylinders 43 rotate, and the two limit cylinders 43 are respectively connected to the two contraction cylinders 44 through synchronous belts. Therefore, the two contraction cylinders 44 rotate. The multiple contraction cylinders 44 are respectively connected to each other through synchronous belts. Therefore, the multiple contraction cylinders 44 rotate synchronously. The inner wall of the contraction cylinder 44 is threadedly connected to the outer wall of the telescopic column 45. One end of each telescopic column 45 is provided with a push plate 46, and one end of each push plate 46 is provided with a limit rod 47. The limit rods 47 respectively limit the telescopic columns 45. Therefore, the telescopic columns 45 and the push plates 46 are displaced; When the push plates 46 are displaced, two of the push plates 46 respectively push two of the placement seats 23 to be displaced, and the multiple placement seats 23 are respectively connected to each other through multiple connecting columns 25. Therefore, the multiple placement seats 23 are displaced, thereby driving the bottoms of the multiple circuit boards to be displaced, causing the multiple circuit boards to be turned over. The first liquid outlet plate 37 performs a reciprocating displacement motion. The first liquid outlet plate 37 continuously sprays the cleaning agent. The first liquid outlet plate 37 sprays the cleaning agent onto the outer wall of the other side of the circuit board. The cleaning agent dissolves and removes the ink and dirt on the outer walls of both sides of the circuit board, improving the cleaning effect on the surfaces of the multiple circuit boards. After the ink and dirt are dissolved, they fall into the first storage bin 27; After the first liquid outlet plate 37 reciprocates once, the second drive motor 30 is turned off, and the first drive motor 3 is started. The multiple placement plates 17 are displaced. After the multiple placement plates 17 move to the upper end of the second storage bin 28, the first drive motor 3 is turned off, and the second drive motor 3 is started to drive the two second limit shafts 40 to rotate. The outer walls of the two second limit shafts 40 are threadedly connected to the inner wall of the second liquid outlet plate 41. Therefore, the second liquid outlet plate 41 is displaced; When the second liquid outlet plate 41 is displaced, one end of the second liquid inlet pipe 42 extending to the outside of the cleaning bin 2 is externally connected to a water tank. The water pump in the water tank conducts the water source through the second liquid inlet pipe 42 to the second liquid outlet plate 41. At the same time, as the second liquid outlet plate 41 is displaced, the second liquid outlet plate 41 sprays the water source onto the outer wall of one side of the circuit board. The other two push plates 46 respectively push two of the placement seats 23 to be displaced, thereby driving the bottoms of the multiple circuit boards to be displaced, causing the multiple circuit boards to be turned over. The second liquid outlet plate 41 performs a reciprocating displacement motion. The second liquid outlet plate 41 continuously sprays the water source. The second liquid outlet plate 41 sprays the water source onto the outer wall of the other side of the circuit board. The water source flushes the outer walls of both sides of the circuit board, causing the remaining ink and dirt on the outer wall of the circuit board to fall into the second storage bin 28; After the second liquid outlet plate 41 reciprocates once, the second drive motor 30 is turned off, and the first drive motor 3 is started. The multiple placement plates 17 are displaced, and at the same time, the multiple baffle plates 16 are displaced, so that the outlet of the cleaning bin 2 is opened. The multiple placement plates 17 are moved out of the interior of the cleaning bin 2, and the multiple placement plates 17 are moved to the upper end of the guide plate 29. The first drive motor 3 is turned off, and the second drive motor 30 is started to drive the second drive shaft 31 to rotate, thereby driving the fan to rotate, so that an air flow is generated inside the air box 32. The air flow enters the air box 32 through the air inlet pipe 35, and the air flow is transmitted from the air outlet pipe 33 to the air outlet plate 34. The air outlet of the air outlet plate 34 faces the multiple placement plates 17, so as to air-dry the surfaces of the multiple circuit boards. And the residual water sources on the surfaces of the multiple circuit boards fall to the upper end of the guide plate 29, and the residual water sources flow into the second storage bin 28 through the guide plate 29. Then the staff takes out the multiple placement plates 17 from the upper end of the device main body 1; In the present invention, by providing the placement plates 17, the placement seats 23 and the push plate 46, the bottoms of the multiple circuit boards are respectively placed on the upper ends of the multiple placement seats 23, and the upper ends of the multiple circuit boards are respectively movably connected to the multiple placement plates 17. After the first liquid outlet plate 37 sprays the cleaning agent on one outer wall of the circuit board, the push plate 46 is displaced to push the two placement seats 23 to be displaced, thereby driving the multiple placement seats 23 to be displaced, so that the multiple circuit boards are turned over. The first liquid outlet plate 37 continuously sprays the cleaning agent, and the first liquid outlet plate 37 sprays the cleaning agent on the other outer wall of the circuit board. The cleaning agent dissolves and falls off the ink and dirt on the two outer walls of the circuit board, improving the cleaning effect on the surfaces of the multiple circuit boards.
