[0041] Principle and operation process

[0042] The utility model realizes that the entire GPP chip cleaning process can be completed inside the cleaning box 2 by arranging a spray device and a blow-drying device in the cleaning device. When in use, first put the GPP chip on the chip rack, put the chip rack into the cleaning box 2, pour a well-proportioned acid solution into the cleaning box 2, and the acid solution needs to cover the GPP chip. During the reaction of the acid solution with the glass, turn on the circulation pump 5, and the acid solution will flow through the liquid inlet pipe 3, through the circulation pump 5, and then flow out from the liquid outlet pipe 4. During the reaction of the acid solution with the glass, a vortex can be generated inside the cleaning box 2, so that the concentration of the acid solution is the same everywhere inside the cleaning box 2, avoiding the acid solution near the chip from reacting and the surrounding concentration decreasing, which can not achieve the cleaning effect; after the immersion process is completed, open the solenoid valve 61 to let the acid solution be discharged from the drain pipe 6, then turn on the booster pump 13, and the spray head 12 starts to rinse the GPP chip. , deionized water must be used for rinsing. During rinsing, the acid liquid inside the cleaning box 2 can also be rinsed clean. While simplifying the cleaning work of the cleaning box 2, it can also better ensure that the acid liquid added next time will not affect the concentration and the cleaning effect. The spray head 12 is arranged on the rotating seat 121. During the cleaning work of the cleaning box 2, the angle of the spray head 12 can be rotated to thoroughly clean the cleaning box 2 to avoid the acid liquid residue from affecting the next cleaning work; after rinsing, turn on the fan 10 and energize the heating wire 11 to blow dry the chip. A plurality of blowing devices are arranged. By adjusting the position and spacing of the blowing devices, a plurality of eddies can be formed inside the cleaning box 2 to improve the blowing efficiency;

[0043] A specially designed filter sleeve 41 is arranged on the liquid outlet pipe 4. The filter sleeve 41 is a cylindrical structure. Filter holes are arranged on the bottom and side surfaces of the cylinder, and the upper surface is a closed structure, so that the accumulated sediment on the upper surface can be prevented from falling back into the circulation pump 5. The circulation device can effectively prevent the sediment after the acid solution reacts with the glass from circulating and making the acid solution turbid. When the spray head 12 is used to clean the inside of the cleaning box 2, the circulation pump 5 is turned on at the same time to clean the residual acid solution in the circulation pump 5.

[0044] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model.
