Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The utility model is realized in such a way, a device for testing the waterproof performance of a mobile phone, which is characterized by comprising a mounting plate 1, a pressure difference detector 2, a feeding cylinder 3, a guide rail 4, a bottom sealing mould 5, a top sealing mould 6 and a sealing cylinder 7;
the bottom sealing die 5 comprises a sliding groove 51, a hinged part 52, a vent hole 53, a mounting cavity 54 and an exhaust hole 55, the sliding groove 51 is arranged at the lower part of the bottom sealing die 5, the hinged part 52 is arranged on the bottom sealing die 5, the mounting cavity 54 is arranged at one end of the bottom sealing die 5 far away from the hinged part 52, and the vent hole 53 and the exhaust hole 55 are respectively arranged at two ends of the mounting cavity 54 along the direction of the sliding groove 51;
Feed 3 both ends of cylinder and be articulated, can avoid leading to because of the installation problem like this feed 3 piston rod of cylinder and block.
Two guide rails 4 are installed, so that the bottom sealing mould 5 can be prevented from being subjected to unbalance loading moment.
The sealing elements are arranged around the inner part of the mounting cavity 54, so that the sealing performance of the die is guaranteed, and meanwhile, the external interface, which does not need to be detected, of the mobile phone die can be sealed in a targeted manner.
Sealing rings are arranged on the mounting surfaces of the bottom sealing die 5 and the top sealing die 6, so that the sealing performance of the upper and lower bonding surfaces of the dies is ensured.
The sealing cylinder 3 is connected with the top sealing die 6 through threads, so that the required die can be quickly replaced according to the model of the mobile phone.
When the mobile phone sealing device is used specifically, a matched die is selected according to the model of a mobile phone to be detected, the mobile phone die is placed in the installation cavity 54 of the bottom sealing die 5, the top sealing die 6 is connected with the sealing cylinder 7, the button is pressed down, the feeding cylinder 3 pushes the bottom sealing die 5 to the position below the top sealing die 6, the top sealing die 6 is in press fit with the bottom sealing die 5 under the pushing action of the sealing cylinder 7, a closed space is formed outside the mobile phone die due to the fact that the volume of the mobile phone die is slightly smaller than the installation cavity 54, then certain pressure gas is introduced into the installation cavity 54 through the vent hole 53 by an external air pump, the pressure sensor feeds back the pressure value of the closed space to the pressure difference detector 2 for a period of time, the pressure difference detector 2 judges the sealing performance of the mobile phone according to the air pressure change in the closed space, and the result is displayed, if the pressure is reduced, the pressure gas leaks from the sealing space to the inner part of the mobile phone mould, which indicates that the mobile phone has poor sealing performance. After the measurement is finished, the pressure gas in the space is discharged through the exhaust hole 55, the piston rod of the sealing cylinder 7 moves upwards, and the piston rod of the feeding cylinder 3 retracts, so that the airtightness detection of one mobile phone is finished.
