Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, Figure 1 The diagram shown is a front view of the cleaning device in the embodiment; Figure 2 The diagram shown is a cross-sectional view of the cleaning device in the embodiment; Figure 3 What is shown is Figure 2 Enlarged schematic diagram of the structure at point A in the diagram; Figure 4 The diagram shown is a schematic representation of the cleaning device in the cleaning state in the embodiment.

[0026] This device includes:

[0027] Workbench 10;

[0028] Cleaning tank 20, with an open top and mounted on workbench 10, and an ultrasonic generator 21 installed inside the cleaning tank 20;

[0029] The cover 30 is lifted and positioned above the opening of the cleaning tank 20, and the bottom of the cover 30 is provided with multiple hooks 32.

[0030] The support frame 40 has a lifting ring 41 at the top corresponding to the position of the hook 32. The hook 32 and the lifting ring 41 are detachably connected.

[0031] The workbench 10 serves as the basic structure of the entire cleaning device, providing a stable operating platform. The support frame 40 is detachably suspended from the lower end of the cover 30. The support frame 40 is a mesh frame, and the semiconductor material or component to be cleaned is placed in the support frame 40. The ultrasonic generator 21 is used to generate high-frequency vibrations, which are transmitted to the semiconductor material or component to be cleaned through a liquid medium (usually water or a specific cleaning solution), using cavitation to remove surface contaminants such as tiny particles and grease.

[0032] During cleaning, the cover 30 descends, causing the support frame 40 to descend until the semiconductor in the support frame 40 is below the surface of the cleaning fluid for cleaning. Simultaneously, the cover 30 closes the opening of the cleaning tank 20. Figure 4 As shown, this can prevent cleaning fluid from splashing out and also reduce the possibility of external contaminants entering the cleaning tank 20, ensuring the purity of the cleaning environment.

[0033] After cleaning, the cover 30 rises, allowing the support frame 40 to be lifted out of the cleaning solution. Operators do not need to directly contact the cleaning solution. Then, the connection between the hook 32 and the lifting ring 41 is released, and the cleaned semiconductor materials or components are removed, thus speeding up the workflow and improving production efficiency. Simultaneously, it facilitates quick replacement of new items to be cleaned, further enhancing equipment utilization.

[0034] Specifically, the bottom of the cover 30 is provided with multiple traction ropes 31, and the hook 32 is set at the bottom of the cover 30 through the traction ropes 31.

[0035] The bottom of the cover 30 is symmetrically provided with extension feet 33 on both sides. The worktable 10 is provided with a drive unit 34 at the position corresponding to the extension feet 33. The output end of the drive unit 34 is fixedly connected to the extension feet 33.

[0036] The driving component 34 is an electric telescopic rod or cylinder in the prior art, which drives the cover 30 to move up and down.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 The diagram shown is a front view of the cleaning device in the embodiment; Figure 2 The diagram shown is a cross-sectional view of the cleaning device in the embodiment.

[0038] The bottom end of the cover 30 is also provided with a spray assembly 50, which includes a water storage box 51 and multiple nozzles 52 connected to the bottom of the water storage box 51. The nozzles 52 correspond to the positions of the support frame 40.

[0039] After ultrasonic cleaning, the semiconductors inside the support frame 40 can be rinsed by spraying the nozzle 52. By combining ultrasonic cleaning with spray cleaning, various contaminants on the surface of the semiconductor material can be removed more thoroughly.

[0040] Below the workbench 10, there is also a liquid storage tank 60. The cleaning tank 20 is connected to the liquid storage tank 60 through a connecting pipe 70. The liquid storage tank 60 is connected to the water storage box 51 through a connecting pipe 80. A filter screen 62 is detachably installed inside the liquid storage tank 60.

[0041] Specifically, valves 71 are installed on both connecting pipe 70 and connecting pipe 80.

[0042] The liquid storage tank 60 is located below the workbench 10 and is used to store the liquid used in the cleaning process (such as water or a specific cleaning solution). The connecting pipe 70 connects the cleaning tank 20 to the liquid storage tank 60, allowing the cleaning liquid to flow back into the liquid storage tank 60. After passing through the filter screen 62, the returned liquid can effectively filter out impurities, particles and other contaminants in the cleaning liquid. The filtered cleaning liquid can be transported to the water storage box 51 through the connecting pipe 80 to provide cleaning liquid for the spray assembly 50, realizing the repeated recycling of the cleaning liquid.

[0043] Specifically, a slot is provided on the side wall of the liquid storage tank 60, and the filter screen 62 is movably inserted into the slot;

[0044] Furthermore, to ensure the quality of the recycled cleaning fluid, the storage tank 60 can also be equipped with other existing filtration structures; to ensure that the cleaning fluid can be transported smoothly, the storage tank 60 is also equipped with a pump body, which is common in the prior art.

[0045] One section of connecting pipe 2 80 is a flexible telescopic hose 81;

[0046] The flexible telescopic hose 81 ensures that the cover 30 is not restricted by rigid pipes during lifting and lowering, thus guaranteeing smooth operation.

[0047] The cover 30 has a cavity 35 inside, and a section of the connecting pipe 80 away from the liquid storage tank 60 extends into the cavity 35 and its end is connected to the water storage box 51.

[0048] The cavity 35 provides path space for the end section of the connecting pipe 80, making the whole system more compact and efficient, reducing the complexity of the external pipe layout, and also reducing the risk of damage caused by exposed pipes.

[0049] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
