Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention is capable of embodiments in many different forms than those described herein and those skilled in the art will be able to make similar modifications without departing from the spirit of the invention and it is therefore not intended to be limited to the embodiments disclosed below.

Referring to fig. 1, fig. 1 is a dustproof processing process for sealing holes of a mobile phone case according to an embodiment of the present invention, which includes the following steps:

and S10, filling the threaded holes of the mobile phone shell with liquid hydrosol.

The hydrosol is a glue soluble in water, and is filled with the hydrosol in each threaded hole of the mobile phone shell through the glue injection machine during glue injection so as to realize automatic glue injection. In this embodiment, the aqueous solvent comprises the following components by weight: 45 parts of calcium bicarbonate, 22 parts of glycerol, 10 parts of hydroxymethyl cellulose, 10 parts of xanthan gum and 13 parts of water.

And S20, solidifying the hydrosol in the threaded hole at high temperature.

And (4) putting the mobile phone shell injected with the glue into a drying box for high-temperature drying to solidify the hydrosol in the threaded hole so as to tightly seal the threaded hole. In the process of solidifying the hydrosol, the temperature for solidifying the hydrosol is preferably 80-100 ℃, and the time for solidifying the hydrosol is preferably 4-10 min. In this example, the temperature for solidifying the hydrosol is 90 degrees celsius, and the time for solidifying the hydrosol is 5 min.

after the hydrosol is solidified in the threaded hole, the surface of the hand casing is subjected to sand blasting treatment through a sand blasting machine, so that the surface of the mobile phone casing has granular feel and forms certain roughness. During sand blasting, the threaded hole is tightly sealed by the solidified hydrosol, so that foreign matters such as sand grains and sand dust generated in the sand blasting process cannot enter the threaded hole.

And S40, washing the mobile phone shell to remove the hydrosol in each threaded hole.

After the sand blasting is finished, the mobile phone shell is soaked by water, so that hydrosol in the threaded hole is dissolved in water, and the purpose of removing the hydrosol in the threaded hole is achieved. In order to get rid of the in-process of the hydrosol in the screwed hole, can also get rid of the dirt of cell-phone shell face of just, the aquatic still adds except that the finish for get rid of the oil stain on the cell-phone shell. The degreasing agent comprises sodium hydrogen phosphate and sodium hydroxide, and the concentration of the degreasing agent in water is 50 g/L.

In this embodiment, water for removing the hydrosol in the threaded hole is contained in the cleaning device. Referring to fig. 2, fig. 2 shows a cleaning device for washing a mobile phone case according to the present invention, the cleaning device 100 includes a water tank 10 with an open top for containing water, a water inlet pipe 20 and a water outlet pipe 30 communicating with an inner cavity of the water tank 10, and two mobile phone case fixing members 40 disposed on the top of the water tank 10. The water inlet pipe 20 injects water into the water tank 10 by the driving of an external water pump; the water discharging pipe 30 discharges a large amount of water in the water tank 10 dissolved with the hydrosol to the outside of the water tank by the driving of an external water pump; the handset housing mounting assembly 40 is used to secure the handset housing so that the handset housing may be suspended and immersed in water.

Each mobile phone shell fixing component 40 includes two opposite pivot blocks 41 installed on the top of the water tank 10, a rotating rod 43 pivotally connecting the two pivot blocks 41, and a plurality of mobile phone shell clamps 44 installed on the rotating rod 43. The mobile phone shell clamp 44 is used for clamping the mobile phone shell, and the cleaning device 100 can clean and remove glue on a plurality of mobile phone shells at one time by arranging the mobile phone shell clamps 44 connected with the rotating rods 43, so that the glue removing efficiency of the cleaning device 100 is improved; through setting up bull stick 43 pin joint piece 41 for staff's accessible makes the cell-phone shell move to the top of water by rotatory bull stick 43, so that staff can inspect at any time whether the cell-phone shell washs well.

Preferably, the pivot block 41 is provided with a V-shaped groove 42, and the end of the rotating rod 43 is located in the V-shaped groove 42. Through the tip that sets up the bull stick 43 be located the V type groove 42 that the pin joint piece 41 set up, be convenient for on the one hand the dismouting of bull stick 43 on the pin joint piece 41, on the other hand, different sizes's bull stick 43 can be placed to V type groove 42, has improved the commonality of pin joint piece 41.

In one embodiment, the cleaning device further comprises a heating device arranged in the water tank and used for adjusting the temperature of water, and experiments show that in the process of changing the temperature between 0 ℃ and 60 ℃ (the temperature step △ T is 3 ℃, the constant temperature time is set for 1 minute, the solubility of the hydrosol becomes large slope (the inclination angle is larger than 45 ℃) and linearly increases, particularly reaches an extremely high value around 50 ℃ to 60 ℃, although the solubility continuously rises along with the temperature rise, the solubility becomes a slow flat-platform curve (the inclination angle is about 10 ℃) compared with the former large slope increase, and the 50 ℃ is far smaller than the upper temperature limit of the mobile phone shell, so that the 50 ℃ can be safely defined as the optimal cleaning temperature of the hydrosol, the temperature of water heated by the heating device is between 50 ℃ and 60 ℃, and the maximum heating temperature is 50 ℃.

In one embodiment, the cleaning device further comprises a stirring device arranged in the water tank. Agitating unit is used for the water in the stirring water tank, makes water form the swirl in the water tank, helps water fully to dissolve the hydrosol on the one hand, and on the other hand, hydroenergy produces great power in order to go out the hydrosol from the screw hole.

The water in the water tank 10 is replaced at intervals, the water used for cleaning a large amount of hydrosol in the water tank 10 is discharged out of the water tank through the water discharge pipe 30, and then clean water is injected into the water tank 10 through the water inlet pipe 20. Before the purified water is injected into the water tank 10 through the water inlet pipe 20, water may be sprayed into the water tank 10 through the water sprayer to clean the water tank 10, and then the purified water may be discharged to the outside of the tank through the water discharge pipe 30.

And S50, drying the mobile phone shell.

After the water sol is removed from the mobile phone shell, the mobile phone shell is dried by blowing hot air at 50-60 ℃ for 5-10 mm.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
