[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: Reference Figure 1-4An ultrasonic cleaning machine for electroplating pretreatment is shown, comprising a housing 1 and a filter frame 14. The filter frame 14 is used to place the workpiece to be treated. During the cleaning process, debris and residue cleaned off the workpiece falls into the filter frame 14. A drawer 19 is provided inside the filter frame 14. The drawer 19 is used to support a filter plate 18 and facilitates operation of the filter plate 18 by the operator. A connecting assembly is provided inside the drawer 19, including a guide block 17 fixedly connected to the inner side wall of the drawer 19. A communicating groove 25 is formed between the inside of the guide block 17 and the side wall of the drawer 19, providing installation and movement space for a limiting post 21, a sliding block 22, and a spring 23. A limiting post 21 is slidably connected inside the slot 25. The limiting post 21 passes through the drawer 19 and the guide block 17. The limiting post 21 can be slidably engaged and disengaged from the slot on the filter plate 18. When the limiting post 21 is engaged in the slot, it can firmly fix the filter plate 18 in the drawer 19, preventing the filter plate 18 from shifting during the operation of the cleaning machine. When it is necessary to remove the filter plate 18, the limiting post 21 can be moved to disengage it from the slot, and the filter plate 18 can be easily removed. A sliding block 22 is fixedly connected to the side wall of the limiting post 21. The sliding block 22 slides inside the slot 25. The sliding block 22 moves synchronously with the limiting post 21, and its sliding in the slot 25 can ensure the sliding stability of the limiting post 21, while also connecting and supporting the spring 23. A spring 23 is fitted around the outer side of the limiting post 21. One end of the spring 23 is fixedly connected to the side wall of the sliding block 22, and the other end is fixedly connected to the inner side wall of the slot 25. The spring 23 provides elastic force, which, when no external force is applied, pushes the sliding block 22 and the limiting post 21 towards the filter plate 18, causing the limiting post 21 to automatically engage in the slot of the filter plate 18, thus automatically locking the filter plate 18. When it is necessary to disassemble the filter plate 18, an external force pulls the limiting post 21 to overcome the elastic force of the spring 23, causing the limiting post 21 to disengage from the slot. A pull plate 24 is fixedly connected to one end of the limiting post 21. The pull plate 24 facilitates the operator to pull the limiting post 21. By pulling the pull plate 24, the limiting post 21 can be moved more easily, completing the unlocking operation of the filter plate 18. The interior of drawer 19 is equipped with a filter plate 18, which is used to intercept impurities and debris falling from the workpiece during the cleaning process, ensuring the cleanliness of the liquid inside the cleaning machine and preventing impurities from re-adhering to the workpiece and affecting the cleaning effect. The side wall of the filter plate 18 is provided with a slot that matches the limiting post 21. The slot and the limiting post 21 cooperate to realize the stable installation and convenient disassembly of the filter plate 18 in the drawer 19.

[0025] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a placement plate 16 is fixedly connected to the side wall of the sieve frame 14. The placement plate 16 is used to support the workpiece that needs to undergo electroplating pretreatment. Its surface is provided with slots, which allow the liquid during the cleaning process to fully contact all parts of the workpiece, ensuring thorough and complete cleaning. Simultaneously, it facilitates the removal of debris and residue from the workpiece surface through the slots into the drawer 19 below. A connecting plate 15 is fixedly connected to the top of the placement plate 16. The connecting plate 15 connects the placement plate 16 to the connecting block 5, linking the placement plate 16 and the workpiece placed on it to the subsequent drive structure, ensuring the structural integrity and continuity of the entire device. A connecting block 5 is fixedly connected to the top of the connecting plate 15. The connecting block 5 cooperates with the threaded rod 6 and the guide rod 7, and under the drive of the motor 4 and the electric push rod 3, moves the placement plate 16 and the workpiece between different processing chambers 20 to achieve different processing steps. Fixed frames 2 are fixedly connected to both ends of the outer casing 1. The fixed frames 2 provide a mounting base for components such as electric push rods 3, ensuring their stable installation on the outer casing 1 and guaranteeing the structural stability of the entire device. Electric push rods 3 are fixedly connected inside the fixed frames 2. The electric push rods 3 can adjust the height of the moving block 11 by extending or retracting their output ends, thereby controlling the raising and lowering of the drain frame 14. This allows for precise placement of the drain frame 14 into different treatment chambers 20, such as placing the drain frame 14 into a treatment chamber 20 containing hydrochloric acid for acidification treatment. The depth of immersion of the drain frame 14 can be controlled to avoid complete immersion and hydrochloric acid overflow. Moving blocks 11 are fixedly connected to the output ends of the electric push rods 3. The moving blocks 11 move up and down under the drive of the electric push rods 3, and also serve as mounting carriers for components such as the motor 4 and support plate 12. Driven by the motor 4, they can also move horizontally along the guide rod 7, enabling the drain frame 14 to move in different directions. Each side wall of the movable block 11 is fixedly connected to a slider 13. The slider 13 cooperates with the slide rail 10 opened in the inner side wall of the fixed frame 2, which can guide the movable block 11 to move up and down smoothly, ensuring the stability of the movement process, preventing the movable block 11 from shaking or deviating during the movement, and ensuring that the slotted frame 14 can accurately reach the designated position. Each inner side wall of the fixed frame 2 is provided with a slide rail 10, which provides a sliding track for the slider 13. Through cooperation with the slider 13, the movement direction of the movable block 11 is constrained, so that the movable block 11 can only move along the vertical direction defined by the slide rail 10. A support plate 12 is fixedly connected to the side wall of the movable block 11. The support plate 12 is used to support the motor 4, provide a mounting platform for the motor 4, ensure the stability of the motor 4 during operation, and enable it to output power normally to drive the threaded rod 6 to rotate. A motor 4 is fixedly connected to the top of the support plate 12. The motor 4 serves as a power source and drives the threaded rod 6 to rotate through the output end. This, in turn, drives the connecting block 5 to move along the axial direction of the threaded rod 6, thereby enabling the slot frame 14 to move horizontally and allowing the workpiece to pass through different processing chambers 20 in sequence for different processes.A threaded rod 6 is rotatably connected between the two moving blocks 11. Driven by the motor 4, the threaded rod 6 rotates, driving the threaded connecting block 5 to move along the threaded rod 6 using the principle of threaded transmission. This, in turn, moves the slotted frame 14 and the workpiece horizontally, completing the transition between different processing steps. A guide rod 7 is fixedly connected between the two moving blocks 11. The guide rod 7 acts as a guide, and the connecting block 5 slides on the side wall of the guide rod 7. This ensures the accuracy of the moving direction of the connecting block 5 as it moves along the threaded rod 6 under the drive of the motor 4, preventing rotation or deviation during movement and ensuring that the slotted frame 14 moves smoothly above each processing chamber 20. The output end of the motor 4 is fixedly connected to one end of the threaded rod 6. The torque output by the motor 4 is transmitted to the threaded rod 6, driving it to rotate, thereby controlling the horizontal movement of the connecting block 5 and the slotted frame 14. The connecting block 5 is threadedly connected to the side wall of the threaded rod 6. When the threaded rod 6 rotates, the connecting block 5 moves along the axial direction of the threaded rod 6 due to the action of the thread, thereby driving the stencil 14 and the workpiece placed on it to move above different processing chambers 20, completing the switching of different processing steps. The connecting block 5 slides on the side wall of the guide rod 7. The guide rod 7 constrains the movement direction of the connecting block 5, so that the connecting block 5 can only move along the horizontal direction defined by the guide rod 7, ensuring the stability and accuracy of the movement of the connecting block 5, and thus ensuring the positional accuracy of the stencil 14 and the workpiece moving to the designated processing chamber 20. The interior of the outer shell 1 is provided with multiple processing chambers 20. Different processing chambers 20 are used to hold different processing liquids or perform different processing operations. For example, one processing chamber 20 can hold hydrochloric acid for acidification of the workpiece, another processing chamber 20 can hold water for cleaning the acidified workpiece, and other processing chambers 20 can be used for ultrasonic cleaning or air drying. Through the coordinated work of multiple processing chambers 20, comprehensive electroplating pretreatment of the workpiece is achieved. An ultrasonic generator body 8 is installed on the inner side wall of one processing chamber 20. When the ultrasonic generator body 8 is working, it generates ultrasonic waves, creating a cavitation effect in the cleaning fluid within the processing chamber 20. This effectively removes oil, microparticles, and other impurities from the workpiece surface, improving the cleaning effect and providing a better workpiece surface condition for subsequent electroplating processes. A blower 9 is installed on the inner side wall of the other processing chamber 20. After the workpiece has completed cleaning and other processes, the blower 9 dries the workpiece by blowing air, removing residual cleaning fluid and moisture from the workpiece surface. This dries the workpiece surface, facilitating subsequent electroplating and preventing rust or adhesion of the electroplating layer due to residual moisture.

[0026] The working principle of this device is as follows: When using this device, firstly, add hydrochloric acid, clean water, and cleaning solution to the multiple processing chambers 20 in sequence from left to right. Place the workpiece to be processed in the placement plate 16 inside the strainer frame 14. Adjust the height of the moving block 11 by using the electric push rod 3 to place the strainer frame 14 into the processing chamber 20 containing hydrochloric acid, just enough to submerge the workpiece. Do not completely submerge the strainer frame 14. After acidification, rotate the threaded rod 6 by the motor 4 to move the connecting block 5 along the guide rod 7 to complete the water cleaning, ultrasonic cleaning, and air drying in sequence. During this process, the debris and residues cleaned off the workpiece will fall through the placement plate 16 onto the filter plate 18. The operator can pull out the drawer 19 and pull the pull plate 24 to release the limit post 21 from the slot on the filter plate 18, and clean or replace the debris and impurities on the filter plate 18.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
