Example 1

As shown in fig. 1 to 5, the present embodiment provides a precision component sorting and testing apparatus, which includes a rotary table 100, a direction selection module 200, a first functional test module 300, a first loading device 600, a second functional test module 400, a third functional test module 500, and a base 800. The base 800 is used for mounting the rotating platform 100, the direction selecting module 200, the first function testing module 300, the first feeding device 600, the second function testing module 400 and the third function testing module 500;

as shown in fig. 6, the rotary table 100 is provided with a plurality of chucks 110 for chucking the components to be tested, the plurality of chucks 110 are distributed in the circumferential direction of the rotary table 100, and the rotary table 100 transfers the components to be tested to each station in the circumferential direction thereof;

the tested components are clamped in each clamping device 110, wherein the rotating platform 100 rotates around a vertical axis under the driving of the driving mechanism, the clamping device 110 rotates with the tested components along with the rotating platform 100, when the clamping device 110 rotates to a set angular position, the rotating platform 100 stops rotating and keeps at the current angular position, so that each test function module can detect the components in the clamping device 110. The direction selecting module 200 is used for adjusting the direction of the measured element to a predetermined direction and then conveying the element to the next link, the direction selecting module 200 includes a first discharging port 240, and the measured element adjusted to the predetermined direction is conveyed from the first discharging port 240 to the next link;

as shown in fig. 2, in order to facilitate the device under test to perform accurate testing in each testing step, the direction of the device under test is adjusted by the direction selecting module 200 in the present embodiment, so that the device under test is conveyed from the first discharging port 240 disposed in the direction selecting module 200 to the next step after being adjusted to the predetermined direction. The predetermined direction is determined according to the test requirements of the device under test. As shown in fig. 7, the direction selection module 200 includes a static electricity removing fan 210, a second driving mechanism 250, a vibration container 220, and a direction selection channel 230, the second driving mechanism 250 is configured to drive the vibration container 220 to vibrate, the direction selection channel 230 is communicated with the vibration container 220, when a measured element is in a predetermined direction, an outer contour of a projection of the measured element on a reference plane matches a cross-sectional shape of an inner wall of the direction selection channel 230, the reference plane is a plane perpendicular to the predetermined direction, and the static electricity removing fan 210 faces the vibration container 220.

In the embodiment, static electricity generated by mutual friction of the tested elements in the vibration process is removed by using the static electricity fan. The cross section of the inner wall of the direction selecting channel 230 is slightly larger than the outer contour of the measured element in the set direction, so that only the measured element in the set direction can enter the direction selecting channel 230.

In a preferred manner, the second driving mechanism 250 includes a horizontal vibration mechanism and a vertical vibration mechanism. The horizontal vibration mechanism is used for driving the vibration container to rotate back and forth along a horizontal plane, and the vertical vibration mechanism is used for driving the vibration container to reciprocate along the vertical direction. In the vibration direction selection process, the second driving mechanism drives the vibration container to vibrate periodically. In one period, the horizontal vibration mechanism drives the vibration container to rotate clockwise along the horizontal surface, meanwhile, the vertical vibration mechanism drives the vibration container to move vertically upwards, so that the tested element rotates and moves upwards under the action of friction force of the vibration container, and the time consumed in the process is recorded as T1; then the vertical vibration mechanism drives the vibration container to move towards the vertical downward direction, so that the vibration container is quickly separated from the tested element, the tested element can quickly rotate towards the clockwise direction relative to the vibration container under the inertia effect because the vibration container is not hindered by the friction force of the vibration container, meanwhile, the horizontal vibration mechanism drives the vibration container to rotate towards the counterclockwise direction along the horizontal plane, so that the relative rotation angle between the tested element and the vibration container is increased in a short time, and the time consumed in the process is marked as T2; then the vertical vibration mechanism drives the vibration container to move in the vertical upward direction until the rotary vibration container is contacted with the tested element again (the time consumed in the process is recorded as T3;), one period is ended, and the vibration law of the previous period is repeated in the next period. By adopting the vibration law, the embodiment can enable the element to be detected to rotate for a larger angle relative to the rotating container in a shorter time under the condition of smaller amplitude, so that the direction selection of the element to be detected can be completed in a shorter time, and the working efficiency of the direction selection is obviously improved. As a preferable mode, T1: t2: t3=2:1:1, the element to be measured can have enough rotation speed after the vibration period is started by adopting the mode, and the element to be measured can rotate relative to the vibration container by a larger angle in a shorter time. The direction-selecting channel can rotate synchronously with the vibration container in the vibration process. In this embodiment, random vibration, that is, irregular vibration, may be adopted in addition to the periodic regular vibration.

By adopting the mode, the matrix arrangement can be realized by charging one side of the material storage member 620 and discharging the material from the other side, the charging and discharging cannot be influenced mutually, and the tested elements can be kept in the matrix arrangement form in the discharging process. The matrix arrangement is that the storage member 620 moves to a position corresponding to the first discharge port 240 along the first direction under the driving of the first driving mechanism 610, the tested elements sequentially enter the matrix arrangement from the first discharge port 240 to form the storage member 620, and after the matrix arrangement is that the storage member 620 is loaded with a sufficient amount of tested elements, the matrix arrangement is that the storage member 620 moves to a position corresponding to the first functional test module 300 along the first direction under the driving of the first driving mechanism 610. The matrix arrangement is that the storage device 620 can transfer the stored tested components to the first functional testing module 300 at one time, after the tested components are transferred, the first functional testing module 300 tests the tested components, and the matrix arrangement is that the storage device 620 can quickly return to the position corresponding to the first discharging port 240 for next filling.
