The invention aims to provide a sand and dust test device for a mobile phone camera module, so that sand and dust in a box body can be dispersed more uniformly.
In order to achieve the purpose, the technical scheme of the invention is as follows: the sand and dust testing device for the mobile phone camera module comprises a box body and a hopper, wherein the hopper is positioned on the top of the box body, the box body is rotatably connected with a vertical rotating pipe, a discharge hole of the hopper is opposite to the top end of the rotating pipe, the bottom end of the rotating pipe is communicated with a vertical discharge barrel, the bottom of the discharge barrel is sealed, a plurality of discharge holes are formed in the circumferential side surface of the discharge barrel, a plurality of first fan blades are fixedly connected onto the rotating pipe, a motor is fixedly connected onto the bottom of the box body, a plurality of second fan blades are fixedly connected onto an output shaft of the motor, the first fan blades and the second fan blades are arranged oppositely, and the rotating direction of the rotating pipe is opposite; the box body is also provided with a driving mechanism for driving the rotating pipe to rotate.
The working principle and the effect of the scheme are as follows: the hopper is used for adding the sand dust material. Because the top of rotating tube is relative with the discharge gate of hopper, the material that so adds drops in the rotating tube, because the intercommunication has a play feed cylinder on the bottom of rotating tube, the sand and dust in the event rotating tube drops in the play feed cylinder. The driving mechanism is used for driving the rotating pipe to rotate, when the rotating pipe rotates, the rotating pipe drives the discharging barrel to rotate together, and the sand dust in the discharging barrel is thrown out from the discharging hole under the action of the centrifugal force of the discharging barrel rotation, so that the sand dust thrown out from the discharging barrel can be dispersed in the radial direction around the discharging barrel. Meanwhile, when the rotating pipe rotates, the rotating pipe drives the first fan blades to rotate, and the first fan blades blow the sand dust downwards, so that the sand dust can be dispersed downwards. In addition, the motor drives the second fan blade to rotate, the second fan blade blows sand and dust upwards, and the blowing direction of the second fan blade is opposite to the downward falling direction of the sand and dust, so that the falling speed of the sand and dust is reduced, the floating time of the sand and dust in the box body is prolonged, and the test effect is improved. Simultaneously, because the rotation direction of rotating tube is opposite with the rotation direction of motor, the rotation direction of event first flabellum and second flabellum is opposite, first flabellum rotates the gas flow direction who makes gaseous flow direction and second flabellum opposite like this, the rotation of second flabellum makes the gas flow direction in the box more disorderly, thereby make the direction of gas flow in the box more mixed and disorderly, random, the sand and dust also can random motion in the box like this, make the effect of sand and dust dispersion in the box better.
In conclusion, the sand and dust are dispersed in the radial direction of the discharge cylinder through the rotation of the discharge cylinder, and the sand and dust can move vertically and downwards due to the blowing of the first fan blades, so that the sand and dust are subjected to downward and transverse dispersing forces simultaneously, and the sand and dust are dispersed primarily uniformly; the floating time of the sand dust can be prolonged by the upward blowing of the second fan blades, so that the sand dust can be dispersed in the box body for a long time, and the time guarantee is won for the uniform dispersion of the sand dust; through the cooperation of first flabellum and second flabellum for the air current in the box is comparatively disorderly, thereby makes the random floating of sand and dust, and the dispersion effect of sand and dust further improves. From this, make more even of sand and dust dispersion in the box through this scheme for experimental simulation effect is more lifelike, has guaranteed experimental effect.

Because the elastic unit is connected between the rotating pipe and the discharging barrel, the discharging barrel can move up and down. Therefore, the discharging barrel and the second fan blade are in the rotating process, the first magnet block and the second magnet block can be intermittently opposite, when the first magnet block and the second magnet block are opposite, the second magnet block generates repulsive force to the first magnet block, the first magnet block enables the discharging barrel to move upwards, when the first magnet block and the second magnet block are staggered, the repulsive force between the second magnet block and the first magnet block is reduced, the discharging barrel can move downwards under the action of self gravity, the discharging barrel can continuously move upwards and downwards in a reciprocating mode, and therefore the discharging barrel can continuously vibrate upwards and downwards, and sand and dust in the discharging barrel can be favorably made to come out of the discharging hole.
Furthermore, the elastic unit comprises a tension spring and a telescopic cylinder, a spring cavity is formed in the side wall of the telescopic cylinder, the tension spring is located in the spring cavity, two ends of the tension spring are fixedly connected to the bottom end of the rotating pipe and the top end of the discharging cylinder respectively, and two ends of the telescopic cylinder are fixedly connected to the bottom end of the rotating pipe and the top end of the discharging cylinder respectively.
