[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 The utility model provides a high-stability and high-efficiency ultrasonic cleaning circuit board fixture, including a U-shaped mounting plate 1, and also includes:

[0026] The rotating shaft 2 is rotatably connected to the inner wall of the U-shaped mounting plate 1. The outer surface of the rotating shaft 2 is fixedly sleeved with a mounting roller 3. Four mounting seats 4 are evenly fixed on the outer surface of the mounting roller 3. The surface of the mounting seat 4 is provided with a card slot. A lever 5 is provided on one side of the mounting seat 4 corresponding to the card slot. Clamping components 6 are provided on both sides of the mounting seat 4 corresponding to the lever 5.

[0027] There are four limit rods 7 and they are fixed on one side of the support rod 5 respectively. The outer surface of the rotating shaft 2 is provided with a limit assembly 8 corresponding to the fixed rod 12, and the surface of the U-shaped mounting plate 1 is provided with a transmission assembly 9 that matches the rotating shaft 2.

[0028] It is worth noting that the surfaces of the mounting base 4 and the support rod 5 are both provided with rectangular through holes, so that the circuit board can have more area in contact with the cleaning liquid when being clamped.

[0029] Further as Figure 2 and Figure 4 As shown, it is worth mentioning that the clamping assembly 6 includes two fixed blocks 64 fixed on both sides of the mounting seat 4, and a movable rod 61 is movably passed through one side of the fixed block 64. The end of the movable rod 61 is fixed to the surface of the push rod 5, and the outer surface of the movable rod 61 is fixed with a connecting ring 62. The outer surface of the movable rod 61 is provided with a first spring 63, one end of the first spring 63 is fixed to the connecting ring 62, and the other end of the first spring 63 is fixed to the inner wall of the fixed block 64.

[0030] Further as Figure 2 and Figure 6 As shown, it is worth mentioning that the limiting assembly 8 includes a limiting groove 81 opened on the outer surface of the rotating shaft 2, and the outer surface of the rotating shaft 2 is provided with a limiting plate 82 corresponding to the limiting groove 81 sliding sleeve, and the surface of the limiting plate 82 is evenly provided with four limiting holes 83 corresponding to the limiting rod 7.

[0031] Further as Figure 1 As shown, it is worth mentioning that the transmission assembly 9 includes a drive motor 91 fixedly mounted on the surface of the U-shaped mounting plate 1, a first gear 92 is fixedly sleeved on the outer surface of the rotating shaft 2, and a second gear 93 is rotatably connected to the inner side of the U-shaped mounting plate 1. The first gear 92 and the second gear 93 are meshed for transmission, and the output end of the drive motor 91 is coaxially connected to the second gear 93.

[0032] It is worth noting that: the second gear 93 is driven to rotate by the driving motor 91, so that the second gear 93 drives the first gear 92 to rotate, so that the rotating shaft 2 drives the mounting roller 3 to rotate, and then drives the circuit board in the mounting seat 4 to rotate. When the rotating circuit board moves in the liquid, the circuit board will come into contact with more cleaning liquid, thereby increasing the contact area between the cleaning liquid and the surface of the circuit board, which helps to more comprehensively remove dirt and grease on the surface of the components. At the same time, the movement of the circuit board will also promote the flow of cleaning liquid in the cleaner, which helps to remove dirt and particles in the cleaning liquid and prevent them from re-adhering to the circuit board.

[0033] Further as Figure 1 and Figure 3As shown, it is worth mentioning that four L-shaped support rods 10 distributed in a rectangular shape are fixed to the outer surface of the U-shaped mounting plate 1, and a fixed frame 11 is fixed to the end of the L-shaped support rod 10. A fixed rod 12 is fixed to the inner wall of the fixed frame 11. The outer surface of the fixed rod 12 is slidably sleeved with a clamping rod 13, and the outer surface of the fixed rod 12 is sleeved with a second spring 14. One end of the second spring 14 is fixed to the surface of the clamping rod 13, and the other end of the second spring 14 is fixed to the inner wall of the fixed frame 11. A grip rod 15 is fixed to the top surface of the clamping rod 13, and the grip rod 15 facilitates the movement of the clamping rod 13.

[0034] This solution has the following working process: usually the circuit board to be cleaned is placed in the grid frame, and then the grid frame is placed in the ultrasonic cleaner for cleaning. However, when the circuit boards are piled up in the frame for cleaning, it is not easy to limit and clamp them, which makes the cleaning effect of the circuit boards poor. At the same time, wear and tear easily occurs between the circuit boards, affecting the cleaning efficiency of the circuit boards. By placing more circuit boards in the card slots of the mounting seat 4, the connecting ring 62 and the movable rod 61 are pushed under the elastic force of the first spring 63, so that the rod 5 clamps and limits the circuit boards. After clamping, the limit plate 82 on the rotating shaft 2 is pulled so that the limit hole 83 on the limit plate 82 is clamped into the limit rod 7, thereby The limit rod 7 is limited to maintain the stability after being clamped by the rod 5, and then the U-shaped mounting plate 1 is placed in the cleaner, the grip rod 15 is pulled, and the fixed frame 11 is placed on both sides of the cleaner. Under the elastic force of the second spring 14, the clamping rod 13 is pushed to slide on the fixed rod 12, so that the clamping rod 13 clamps the side wall of the cleaner, thereby placing and limiting the U-shaped mounting plate 1. At this time, the circuit board is immersed in the cleaning liquid of the cleaner for ultrasonic cleaning. At the same time, the driving motor 91 drives the second gear 93 to rotate, so that the second gear 93 drives the first gear 92 to rotate, so that the rotating shaft 2 drives the mounting roller 3 to rotate, and then drives the circuit board in the mounting seat 4 to rotate, thereby improving the cleaning efficiency.

[0035] According to the above working process, it can be known that: through the setting of multiple mounting seats 4, push rods 5 and clamping components 6, the function of clamping and limiting multiple circuit boards at the same time is realized, avoiding the accumulation of multiple circuit boards, thereby improving the cleaning effect of the circuit boards and the stability during the cleaning process, and at the same time improving the cleaning efficiency. Through the cooperation between the limiting component 8 and the clamping component 6, the function of limiting the limiting rod 7 is realized, thereby limiting the push rod 5, and then improving the stability of the circuit board during clamping. Through the setting of the transmission component 9, the circuit board rotates during the cleaning process, thereby further improving the cleaning effect; through the setting of structures such as the clamping rod 13, the second spring 14 and the fixed frame 11, the function of limiting the U-shaped mounting plate 1 is realized, which facilitates the placement of the entire device and improves the convenience of operation.

[0036] The drive motor 91 can be purchased on the market. The drive motor 91 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
