Description

Technical Field

[0001] This utility model relates to the technical field of water washing devices, specifically a water washing device for PCB production. Background Technology

[0002] PCB boards are indispensable components in electronic devices, mainly used to realize electrical connections between electronic components. By laying conductive copper foil in a pattern on insulating material, PCB boards form electrical connections between electronic components. They provide circuit structure and organization, support and fix electronic components, and ensure wiring and electrical connections between them. During the production process, PCB boards may have chemical solutions adhering to their surfaces. In order to avoid the chemical solutions affecting their performance, PCB boards need to be cleaned before they can be shipped out. To better clean PCB boards, a PCB production water washing device is proposed.

[0003] As disclosed in the authorization announcement number CN219843789U, a water washing device for PCB board production includes a water washing tank for washing PCB boards. The water washing tank is equipped with a fixed frame, and the fixed frame is equipped with a cleaning roller for cleaning the surface of the PCB board. The adjustment mechanism includes a mounting plate, a screw, a fixed cylinder, a limiting cylinder, an annular block, and an annular plate. The screw is rotatably mounted on the top of the fixed frame. The mounting plate is located on the top of the water washing tank. The annular plate is located in the inner cavity of the fixed cylinder. The water washing tank has an installation groove, and the mounting plate is slidably inserted into the inner cavity of the installation groove.

[0004] Although it achieves the mutual cooperation of mounting plate, screw, fixed cylinder, fixed frame, limiting cylinder, annular block and annular plate, the screw rotates on the mounting plate, the screw drives the annular plate to rotate in the inner cavity of the fixed cylinder, and the annular plate drives the fixed frame to move up and down, which is conducive to adjusting the height of the cleaning roller, and thus conducive to washing PCB boards of different thicknesses.

[0005] However, the existing water washing device does not solve the problem that it is not convenient to elastically clamp and input PCB boards of different sizes during use, nor is it conducive to reciprocating oscillation and uniform spraying cleaning of PCB boards, which affects the cleaning effect and the flexibility of use. Utility Model Content

[0006] The purpose of this utility model is to provide a water washing device for PCB production, so as to solve the problems mentioned in the background art, which are not convenient for elastically clamping and inputting PCBs of different sizes, are not conducive to reciprocating swinging and uniform spraying cleaning of PCBs, and affect the cleaning effect and the flexibility of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PCB production water washing device, comprising a collection box and a support plate. Two sets of support plates are symmetrically installed on the top of the collection box. Electric push rods are installed on the side walls of the support plates. Push arms are installed at the output ends of the electric push rods. A bearing frame is installed at the end of each push arm away from the electric push rod. Two sets of lower conveyor belts are arranged above the collection box, and the lower conveyor belts are respectively connected to the two sets of bearing frames. An upper conveyor belt is arranged above each of the lower conveyor belts. Sliding rods are installed between the lower and upper conveyor belts, and the sliding rods are slidably connected to the two sets of lower and upper conveyor belts respectively. Springs are installed inside each bearing frame, and the bottom end of the springs is connected to the upper conveyor belt. The upper conveyor belt is slidably connected to the bearing frame. A support frame is installed on the top of the collection box on one side of the support plate.

[0008] Preferably, the top of the support frame is equipped with a track, and the top of the two sets of tracks is equipped with a placement rack.

[0009] Preferably, a drive motor is installed at the bottom of the placement rack, and the drive motor is fixedly connected to the placement rack.

[0010] Preferably, a linkage arm is installed at the output end of the drive motor, and the linkage arm is fixedly connected to the output end of the drive motor.

[0011] Preferably, a movable roller is installed at the end of the linkage arm away from the drive motor, and the movable roller is movably connected to the linkage arm.

[0012] Preferably, a swing frame is provided between the tracks, and the movable roller is slidably connected to the swing frame.

[0013] Preferably, two sets of auxiliary wheels are symmetrically and movably installed on the side wall of the swing frame, and the auxiliary wheels are slidably connected to the track.

[0014] Preferably, the bottom end of the swing frame is equipped with multiple sets of cleaning racks at equal intervals, and the cleaning racks are fixedly connected to the swing frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the water washing device not only realizes the convenient elastic clamping of PCB boards of different sizes, which facilitates the reciprocating swinging and uniform spraying cleaning of PCB boards, but also improves the cleaning effect and the flexibility of use.

[0016] The cleaning solution is connected to the cleaning rack via a flexible hose. The PCB board to be cleaned is then placed between the lower and upper conveyor belts. Supported by springs, the upper conveyor belt moves downwards within the support frame, bringing it into contact with the lower conveyor belt. The lower and upper conveyor belts clamp and secure the PCB board. Then, both conveyor belts are simultaneously activated, moving the PCB board. When the PCB board reaches the cleaning rack position, a water pump sprays the cleaning solution onto the surface of the PCB board through the rack. The cleaning solution cleans the surface of the PCB board. The drive motor rotates the linkage arm, which in turn rotates the movable roller. The movable roller causes the swing frame to swing back and forth inside the track, which in turn causes the cleaning frame to swing back and forth. The cleaning frame then sprays the PCB board with the cleaning solution, improving the uniformity of the cleaning solution spray. The used cleaning solution falls into the collection box and is collected. This system allows for convenient and flexible clamping of the PCB board, facilitating uniform spraying and cleaning of the PCB board and improving the cleaning effect.

[0017] When the width of the PCB board to be cleaned is different, the electric push rod drives the push arm to retract, and the push arm drives the lower conveyor belt and the upper conveyor belt to move away from each other, thereby adjusting the distance between the two sets of lower and upper conveyor belts, thus adapting to PCB boards of different widths and improving the flexibility of use.

The electric push rods 11 are used for power driving. Push arms 10 are installed at the output ends of the electric push rods 11. A bearing frame 9 is installed at the end of the push arm 10 away from the electric push rod 11. Two sets of lower conveyor belts 5 are arranged above the collection box 1, and the lower conveyor belts 5 are respectively connected to the two sets of bearing frames 9. An upper conveyor belt 6 is arranged above the lower conveyor belts 5. A sliding rod 7 is installed between the lower conveyor belts 5 and the upper conveyor belts 6, and the sliding rod 7 is slidably connected to the two sets of lower conveyor belts 5 and upper conveyor belts 6 respectively. A spring 8 is arranged inside the bearing frame 9, and the bottom end of the spring 8 is connected to the upper conveyor belt 6. The upper conveyor belt 6 is slidably connected to the bearing frame 9. A support frame 3 is installed on the top of the collection box 1 on one side of the support plate 2.

[0026] The cleaning solution is connected to the cleaning rack 18 via a flexible hose. The PCB board to be cleaned is then placed between the lower conveyor belt 5 and the upper conveyor belt 6. Supported by the elastic spring 8, the upper conveyor belt 6 moves downwards within the support frame 9, bringing it into contact with the lower conveyor belt 5. The lower and upper conveyor belts 5 and 6 clamp and secure the PCB board. Then, both conveyor belts 5 and 6 are simultaneously activated, moving the PCB board. When the PCB board reaches the cleaning rack 18, the cleaning solution pump is turned on, spraying the cleaning solution through the cleaning rack 18 onto the surface of the PCB board. The cleaning solution cleans the PCB board. The surface of the board is cleaned with the cleaning solution. The drive motor 13 is turned on, which drives the linkage arm 14 to rotate. The linkage arm 14 drives the movable roller 15 to rotate. With the sliding cooperation between the auxiliary wheel 16 and the track 4, the movable roller 15 drives the swing frame 17 to swing back and forth inside the track 4. The swing frame 17 drives the cleaning frame 18 to swing back and forth. The cleaning frame 18 performs reciprocating swing spray cleaning on the PCB board to improve the uniformity of the cleaning solution spray. The used cleaning solution falls into the collection box 1 and is collected by the collection box 1. This realizes convenient elastic clamping of the PCB board, which facilitates the reciprocating swing uniform spray cleaning of the PCB board and improves the cleaning effect.

[0027] The top of the support frame 3 is equipped with a track 4, and the top of the two sets of tracks 4 are equipped with a placement frame 12. The bottom of the placement frame 12 is equipped with a drive motor 13, which serves as a power drive and is fixedly connected to the placement frame 12. The output end of the drive motor 13 is equipped with a linkage arm 14, and the linkage arm 14 is fixedly connected to the output end of the drive motor 13.

[0028] A movable roller 15 is installed at the end of the linkage arm 14 away from the drive motor 13, and the movable roller 15 is movably connected to the linkage arm 14. A swing frame 17 is provided between the tracks 4, and the movable roller 15 is slidably connected to the swing frame 17.

[0029] Two sets of auxiliary wheels 16 are symmetrically and movably installed on the side wall of the swing frame 17, and the auxiliary wheels 16 are slidably connected to the track 4. Multiple sets of cleaning racks 18 with equal spacing are installed at the bottom of the swing frame 17, and the cleaning racks 18 are fixedly connected to the swing frame 17.

[0030] When the PCB boards to be cleaned have different widths, the electric push rod 11 is opened, which drives the push arm 10 to retract. With the sliding cooperation between the lower conveyor belt 5 and the slide rod 7, and the sliding cooperation between the upper conveyor belt 6 and the slide rod 7, the push arm 10 drives the lower conveyor belt 5 and the upper conveyor belt 6 to move away from each other, thereby adjusting the distance between the two sets of lower conveyor belts 5 and upper conveyor belts 6, so as to adapt to the input of PCB boards of different widths and improve the flexibility of use.

[0031] Working principle: The cleaning solution is connected to the cleaning rack 18 through a flexible hose. The PCB board to be cleaned is then placed between the lower conveyor belt 5 and the upper conveyor belt 6. Supported by the elastic spring 8, the upper conveyor belt 6 moves downwards within the support frame 9, bringing it into contact with the lower conveyor belt 5. The lower and upper conveyor belts clamp and fix the PCB board in place. Then, both conveyor belts 5 and 6 are simultaneously activated, moving the PCB board. When the PCB board reaches the cleaning rack 18, the cleaning solution pump is turned on, spraying the cleaning solution through the cleaning rack 18 onto the surface of the PCB board. The cleaning solution cleans the surface of the PCB board. The drive motor 13 drives the linkage arm 14 to rotate, which in turn drives the movable roller 15 to rotate. The auxiliary wheel 16 slides against the track 4. The movable roller 15 drives the swing frame 17 to swing back and forth inside the track 4. The swing frame 17 drives the cleaning frame 18 to swing back and forth. The cleaning frame 18 sprays the PCB board with the back and forth swing to improve the uniformity of the cleaning solution spray. The used cleaning solution falls into the collection box 1 and is collected by the collection box 1. When the PCB boards to be cleaned are of different widths, the electric push rod 11 is opened. The electric push rod 11 drives the push arm 10 to retract. With the sliding cooperation between the lower conveyor belt 5 and the slide rod 7, and the sliding cooperation between the upper conveyor belt 6 and the slide rod 7, the push arm 10 drives the lower conveyor belt 5 and the upper conveyor belt 6 to move away from each other, thereby adjusting the distance between the two sets of lower conveyor belt 5 and upper conveyor belt 6, so as to adapt to the input of PCB boards of different widths and facilitate the input and cleaning of PCB boards of different widths. The above is the complete usage of the water washing device for PCB production.
