Description

Technical Field

[0001] The utility model relates to the technical field of cleaning nozzles of heat dissipation paste, in particular to a cleaning mechanism for a nozzle of heat dissipation paste. Background Art

[0002] The application of thermal paste is a manual operation, that is, the operator uses auxiliary tools to apply thermal paste to one side of the product. The thermal paste has a high viscosity and is not easy to clean. People usually use non-woven cloth dipped in alcohol to wipe it, which is more common in the coating manufacturing industry.

[0003] Prior art, such as the utility model with announcement number CN219003496U, discloses a glue nozzle cleaning mechanism, which includes a vertically arranged substrate, a feeding wheel, a receiving wheel and three idle wheels arranged on one side of the substrate; the first idle wheel and the second idle wheel are located at the same height; the second idle wheel and the third idle wheel are located on the same vertical plane, and the second idle wheel is above; the dust-free cloth tape starts from the feeding wheel, passes around the first idle wheel, the second idle wheel and the third idle wheel in sequence, and is then reeled up by the receiving wheel. The above-mentioned glue nozzle cleaning mechanism adopts a receiving wheel and a feeding wheel, and is composed of three idle wheels to realize the unwinding and reeling of the dust-free cloth tape. The dust-free cloth tape between the first idle wheel and the second idle wheel at the same height provides a position for wiping the glue nozzle. At the same time, the movement of the dust-free cloth tape during reeling is used instead of the traditional glue nozzle movement method for cleaning, which has a better effect. The dust-free cloth tape that has wiped the glue nozzle is reeled up by the reeling wheel, which ensures that the dust-free cloth tape that wipes the glue nozzle is clean each time, thereby ensuring the cleaning effect.

[0004] During the cleaning of the thermal paste, it was found that when cleaning the thermal paste nozzle, a non-woven cloth dipped in alcohol is usually used for wiping. The liquid after wiping may cause relevant contamination to surrounding items, and multiple wipes are required. If the wiping is not clean, the use of alcohol needs to be strictly controlled, which can easily cause safety hazards. Utility Model Content
