Technical Field
[0001] This utility model relates to the field of circuit board immersion cleaning technology, specifically a circuit board immersion cleaning device. Background Technology
[0002] Circuit boards are fundamental components in electronic devices, used to support and connect various electronic components. They are one of the core components of electronic products; almost all electronic devices, including mobile phones, computers, and home appliances, contain circuit boards. The main function of a circuit board is to provide a platform to support the connection of electronic components (such as resistors, capacitors, transistors, and integrated circuits), and to transmit current and signals through lines to complete the required electrical functions. During the manufacturing process, flux and similar substances are used, leaving traces on the board surface such as residue, fingerprints, and sweat stains. These residues can attract oil and dust, adversely affecting the operation of the circuit board, especially under high-frequency and high-voltage conditions. Therefore, circuit boards need to be immersed and cleaned during production.
[0003] Patent application CN213349946U discloses a circuit board immersion washing device, including a box, a support plate, a pad, and a stirring mechanism. The side walls of the box are fitted with doors via multiple sets of spring hinges, and symmetrical handles are installed on the doors. A side plate is fixedly installed on the left side wall of the box, and a drive motor is mounted on the side plate via a slotted frame. The stirring mechanism is located inside the box and includes a drive motor, a rotating shaft, a cross blade, and a fan blade. The output shaft of the drive motor is fixedly mounted with a transmission disc via a coupling, and the surface of the transmission disc has two belt grooves. The transmission disc is rotatably connected to a bearing seat mounted on the side wall of the box, and the transmission disc is connected to two sets of driven discs via belts. This circuit board immersion washing device not only stirs and mixes the added cleaning agent, enhancing the immersion effect, but also rinses the immersed circuit board again to prevent residual cleaning agent from damaging the circuit board.
[0004] However, existing circuit board immersion washing devices are inconvenient to dry after immersion washing, and the circuit boards are kept stationary during immersion washing, which makes the immersion washing effect of the device not good enough. Therefore, the device is not very effective and not very practical. Therefore, a circuit board immersion washing device is proposed to address the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Please see Figure 1-4 As shown, a circuit board immersion cleaning device includes an immersion tank 1, wherein a through threaded hole 4 is provided on the upper surface of the immersion tank 1, and a threaded cover 5 is threadedly connected inside the threaded hole 4.
[0028] The threaded cover 5 is provided with a movable component 7. The bottom of the movable component 7 extends to the bottom of the threaded cover 5. A placement frame 9 is fixedly installed at the bottom of the movable component 7. A plurality of evenly distributed partitions 10 are fixedly connected inside the placement frame 9.
[0029] A drying component 2 is provided on the front surface of the immersion tank 1, and the rear surface of the drying component 2 extends into the interior of the immersion tank 1. During operation, the immersion tank 1 is supported and placed by the support legs at the bottom. After the immersion tank 1 is placed securely, the threaded cover 5 is rotated to move from the threaded hole 4. After the threaded cover 5 rotates, it drives the moving component 7 and the placement frame 9 to move out of the immersion tank 1. Then, the circuit boards to be immersed are placed inside the placement frame 9, and multiple circuit boards are separated by the partition 10. Finally, the placement frame 9 is placed inside the immersion tank 1. Furthermore, the threaded connection between the threaded cap 5 and the threaded hole 4 ensures a secure connection between the threaded cap 5 and the immersion tank 1. Then, the moving component 7 allows the placement frame 9 and the circuit board inside the placement frame 9 to be immersed in the immersion agent inside the immersion tank 1. The moving component 7 also ensures a better immersion effect for the circuit board. After immersion, the drying component 2 can dry the immersed circuit board, which facilitates the drying process after immersion. At the same time, the placement frame 9 is designed with a mesh structure on all sides, which will not affect the immersion agent from entering the placement frame 9 to immerse the circuit board.
[0030] The moving component 7 includes an inner groove 73 formed inside the threaded cover 5. A cam 74 is rotatably connected to the right side of the inner groove 73 via a rotating rod 72. A motor 71 is fixedly installed on the top right side of the threaded cover 5, and the output end of the motor 71 is fixedly connected to the top of the rotating rod 72. A through-type sliding groove 712 is formed on the left side of the lower surface inside the inner groove 73. A slider 76 is slidably connected inside the sliding groove 712. The top of the slider 76 is inserted into the inner groove 73, and the slider 76 is slidably connected to the inner groove 73. A pressing rod 75 is fixedly connected to the right side of the slider 76. The bottom of the slider 76 penetrates the bottom of the threaded cover 5. An electric lifting rod 77 is fixedly connected to the bottom of the slider 76, and the output end of the electric lifting rod 77 is fixedly connected to the placement frame 9. A limit component is provided between the left side of the slider 76 and the left side of the inner groove 73. During operation, when the circuit board inside the placement frame 9 is immersed in the washing agent... During immersion washing, the placement frame 9 can be moved by the moving component 7, and the electric lifting rod 77 is energized to drive the placement frame 9 into the immersion solution for immersion washing. Then, the motor 71 is energized during immersion washing, and the motor 71 drives the rotating rod 72 and the cam 74 to rotate. Then, the rotating cam 74 squeezes the pressing rod 75, and the pressing rod 75 drives the slider 76 to slide inside the inner groove 73 and the slide groove 712 through the limiting component. Then, the slider 76 slides and drives the electric lifting rod 77 and the placement frame 9 to move inside the immersion solution. The cooperation of the limiting component and the rotation of the cam 74 allows the placement frame 9 to move back and forth inside the immersion solution for immersion washing, and the circuit board inside the placement frame 9 is in a moving state during immersion washing. In this way, there is friction between the immersion solution and the circuit board, and the immersion effect of the circuit board is better.
[0031] The limiting component includes a limiting groove 710 formed on the left side inside the inner groove 73. A limiting block 79 is slidably connected inside the limiting groove 710. A spring 711 is fixedly connected between the limiting block 79 and the limiting groove 710. A connecting rod 78 is fixedly connected to the right side of the limiting block 79. The right end of the connecting rod 78 is fixedly connected to the left side of the slider 76 inside the inner groove 73. The right end of the pressing rod 75 is arc-shaped and fits against the left side of the cam 74. During operation, the movement of the slider 76 moves the connecting rod 78. The compression is applied, and the connecting rod 78 is compressed, which drives the limiting block 79 to slide in the limiting groove 710. The sliding of the limiting block 79 in the limiting groove 710 makes the movement of the slider 76 more stable. Then, the sliding of the limiting block 79 compresses the spring 711, making the spring 711 have a rebound force. The rebound force of the spring 711 facilitates the reset of the slider 76. In addition, the rotation of the cam 74 can make the slider 76 move back and forth. At the same time, the right end of the compression rod 75 is set in an arc shape to facilitate the compression of the compression rod 75 by the cam 74.
[0032] The drying assembly 2 includes a support plate 24 fixedly connected to the front surface of the immersion tank 1. An air pump 23 is fixedly installed on the top of the support plate 24. A connecting pipe 22 is fixedly installed at the air outlet of the air pump 23. The rear end of the connecting pipe 22 extends into the interior of the immersion tank 1, and a nozzle 21 is fixedly installed at the rear end of the connecting pipe 22. During operation, after the circuit board inside the placement frame 9 is immersed, the circuit board is removed from the immersion agent by the electric lifting rod 77 for draining. Then, the air pump 23 is powered on to make the air pump 23 work. After the air pump 23 works, it can spray air through the connecting pipe 22 and the nozzle 21. The sprayed air dries the immersed circuit board by blowing air, thereby accelerating the drying of the immersed circuit board and making the device more effective.
[0033] The immersion tank 1 has an inlet pipe 3 connected to the upper left side and an outlet pipe 8 connected to the lower right side. The right end of the outlet pipe 8 is threaded with a cap. During operation, the inlet pipe 3 allows the immersion agent to enter the immersion tank 1 to immerse the circuit board, and the outlet pipe 8 allows the immersion agent to exit the immersion tank 1 for replacement. When the immersion agent flows out, the cap needs to be rotated to open the outlet pipe 8. After the immersion agent in the immersion tank 1 has completely flowed out, the cap is threaded to the outlet pipe 8 to close the outlet pipe 8.
[0034] A handle 6 is fixedly connected to the center of the top of the threaded cover 5; during operation, the handle 6 facilitates the rotation and movement of the threaded cover 5.
[0035] Example 2
[0036] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, handles 2 11 are fixedly connected to the center of both sides of the immersion tank 1; during operation, the handles 2 11 facilitate the movement and handling of the immersion tank 1, thereby facilitating the handling of the device.
