Description

Technical Field

[0001] This utility model belongs to the technical field of chip cleaning devices, specifically relating to a TVS chip cleaning device. Background Technology

[0002] TVS (Transient Voltage Suppressor) chips are critical components used for circuit protection. Typically made of semiconductor materials, they rapidly conduct and clamp voltages when transient overvoltages occur in a circuit, thus protecting downstream circuits from overvoltage damage. However, contaminants introduced during TVS chip manufacturing can affect the chip's electrical performance. Contaminants on the chip surface before packaging can affect the adhesion between the packaging material and the chip. Accumulated contaminants during use can lead to a decrease in the chip's insulation performance. Therefore, chip cleaning equipment is required to clean the chips and ensure their reliability.

[0003] A TVS chip cleaning device with publication number CN219519766U in the prior art includes a cleaning shell, a feeding channel, a discharge port, a water outlet pipe, a placement mechanism, and a cleaning mechanism. The placement mechanism includes an elastic mounting component and a placement component. The elastic mounting component buffers and reduces shock for the placement mesh frame. The nozzle cleans the TVS chip. After cleaning, the electric cylinder drives the rotating baffle to move for convenient discharge. However, this device cannot recycle the cleaning solution, which easily leads to resource waste and lacks multiple cleaning methods, making it impossible to guarantee the uniformity and quality of cleaning. Utility Model Content

[0015] 2. The ultrasonic generator inside the cleaning chamber can use the high-frequency vibration of ultrasonic waves to thoroughly remove dirt from the chip surface, improving the cleaning effect.

[0016] 3. The rotating shaft, mounting rollers, partitions, and slots inside the cleaning tank can neatly and orderly place the chips, increase the contact area between the chips and the cleaning solution, and facilitate the installation and removal of the chips.

[0017] 4. The inlet II, outlet II, and cleaning port on the filter box facilitate the filtration of the cleaned liquid to remove impurities. The cleaning port also facilitates the removal of the filtered impurities.

[0018] 5. The support base and filter cotton inside the filter box can effectively filter the liquid, ensuring the cleanliness of the liquid returning to the cleaning box and reducing secondary contamination of the chip.

[0019] 6. The spray manifold and spray head connected to the bottom of the main spray pipe spray and rinse the chip to further improve the cleaning effect and ensure that there are no residual impurities on the chip surface.

[0020] 7. The circulation mechanism connects the cleaning tank, filter tank and spray main pipe in sequence through circulation pipe I, circulation pipe II and water pump, realizing the recycling of cleaning liquid, saving water resources and reducing cleaning costs.

[0021] 8. The drive mechanism drives the rotating shaft to rotate through the drive motor, drive wheel, transmission track and driven wheel, so that the chips on the mounting roller can be evenly rinsed by the cleaning liquid and subjected to ultrasonic waves during the cleaning process, which improves the uniformity and consistency of cleaning and ensures the cleaning quality of the chips.
