[0041] A screening test method for Bluetooth earphone production, which utilizes the screening test system to perform multiple drop tests on the earphone.

[0042] Implementation process:

[0043] First, adjust the height of the adjustable permanent magnet plate 36 according to the required drop height, and then lock the adjustable permanent magnet plate 36 using the locking mechanism to maintain the current height.

[0044] In the initial state, the screening plate 32 maintains a vertical state, and the left wall of the screening plate 32 is flush with the right wall of the cavity 3, the transmission plate 12 and the supporting net 17 are both in abutment with the right wall of the cavity 3, and the locking piece 14 is separated from the limiting slot 11.

[0045] Open the glass window to place the earphone on the top wall of the supporting net 17, close the glass window to prevent the earphone from popping out when dropping, start the steering engine 4 to rotate the threaded rod 5, thereby driving the connecting plate 7, the movable permanent magnet plate 13, the transmission plate 12, and the supporting net 17 to move upwards, and the adjustable permanent magnet plate 36 is located in front of the connecting plate 7, so the adjustable permanent magnet plate 36 will not hinder the upward movement of the connecting plate 7, when the movable permanent magnet plate 13 moves to the right of the adjustable permanent magnet plate 36, the movable permanent magnet plate 13 is attracted to the left by the magnetic attraction of the adjustable permanent magnet plate 36, the locking piece 14 is inserted into the limiting slot 11 and locked by the pressing type elastic self-locking mechanism, the earphone abuts against the elastic plate 37, and after the supporting net 17 moves to the left of the elastic plate 37, the earphone loses the support of the supporting net 17 and drops onto the top wall of the detection plate 26 in the detection groove 28, the detection groove 28 can limit the movement position of the earphone, and also facilitates the subsequent lifting by the supporting net 17.

[0046] The rudder 4 reverses to make the connecting plate 7 move down, the locking piece 14 moves to the lower side of the adjustable permanent magnet plate 36 and loses the magnetic force of the adjustable permanent magnet plate 36, and then rebounds a small distance to the right, after the bottom wall of the supporting net 17 abuts against the bottom wall of the machine cavity 3, the connecting plate 7 continues to move down to compress the elastic element 16 and the elastic plate 37, the connecting plate 7 presses the pressure rod 9, the pressure rod 9 drives the linkage rod 21 and the rack 22 to move down against the elastic force of the elastic element 38, so as to drive the rack 24, the piston strip 25 and the detection plate 26 to move up through the gear 23, when the top wall of the detection plate 26 moves up to be slightly higher than the detection groove 28, the wedge-shaped block 15 is pushed to move left by the wedge-shaped strip 19, so that the locking piece 14 moves left by a small distance, the locking piece 14 and the pressing type elastic self-locking mechanism in the limiting groove 11 are unlocked, the rudder 4 is reversed, the pressure rod 9, the linkage rod 21 and the rack 22 move up under the elastic force of the elastic element 38, the detection plate 26 moves down, and after the wedge-shaped block 15 is separated from the wedge-shaped strip 19, the top wall of the detection plate 26 is flush with the top wall of the base 1, the movable permanent magnet plate 13, the transmission plate 12 and the supporting net 17 move right under the elastic force of the elastic element 18, the earphone moves along the inclined right wall of the supporting net 17 to the top wall of the supporting net 17 (in actual operation, the top wall of the detection plate 26 may be slightly lower than the top wall of the base 1, but since the curved surface of the earphone surface cooperates with the inclined right wall of the supporting net 17, the earphone cannot be moved to the top wall of the supporting net 17), the supporting net 17 abuts against the right wall of the machine cavity 3, the supporting net 17 lifts the earphone to move up, and the above process is repeated for multiple drop test, only one electric drive part, the rudder 4, can realize the action of releasing and automatically transporting the earphone to a high place, the linkage is strong, the practicability is high, and the automation degree is high, and manual operation is not needed.

[0047] If the earphone needs to be simulated to drop on a wet ground with different water levels for drop test, the piston rod on the air cylinder 33 is elongated, so that the screening plate 32 pushes the clean water to pass through the water pipe 30 and the water hole 27 into the detection groove 28, and the height of the screening plate 32 can control the water level height in the detection groove 28.

[0048] The image acquisition device 34 acquires the appearance image of the earphone, the processing module identifies and analyzes the appearance image of the earphone, so as to analyze the damage degree of the appearance of the earphone, when the damage degree is higher than a preset value, the processing module moves the supporting net 17 to be higher than the screening plate 32, controls the driving mechanism to rotate the shaft and the screening plate 32 counterclockwise by forty-five degrees, so that the screening plate 32 is in an inclined state, after the earphone drops, the earphone falls into the recycling box 39 along the screening plate 32 and the bottom wall of the screening channel 31 to be automatically screened and recycled, and then the screening plate 32 is reversed to reset to a vertical state, so as to avoid hindering the downward movement of the supporting net 17.

[0049] The application has the following beneficial effects:

[0051] The adjustable permanent magnet plate 36 provides stable magnetic attraction positioning and ensures the consistent height of the drop starting position through the locking mechanism, improving the test repeatability and accuracy.

[0052] The detection groove 28 limits the movement of the earphone, cooperates with the detection plate 26, and realizes the re-lifting and lifting control of the dropped earphone through the linkage structure of the gear 23, the rack one 22, the rack two 24, the piston strip 25, the linkage rod 21, the pressure receiving rod 9 and the elastic element three 38, which is compact in structure and reliable in movement.

[0053] In addition, the screening plate 32 and the screening channel 31 construct an automatic screening passage, which can automatically distinguish the damage degree of the earphone appearance in combination with the identification and judgment of the image acquisition device 34 and the processing module, and when the damage degree is too high, it indicates that the earphone is unqualified, the driving mechanism controls the screening plate 32 to tilt and guides the unqualified earphone into the recovery box 39, realizing intelligent screening.

[0054] The water injection structure composed of the water cavity 29, the water pipe 30 and the water hole 27 can realize wet ground simulation test under different water level conditions, enhancing the diversity and authenticity of the test environment.
