With the cooperation of the servo motor 12 and the first servo cylinder 16, the sliding plate 17 can be rotated and moved up and down. First, the sliding plate 17 is moved above the headphone placed at a designated position, so that the air inlet 110 contacts the headphone. Then, the first air pump 18 is started to pump air. At this time, the headphone will be adsorbed by the air inlet 110. Then, the headphone is driven to the testing platform of the testing machine 111 through the movement of the sliding plate 17. The first air pump 18 is turned off to make the headphone fall into the testing slot. The sliding plate 17 is moved away, and the testing machine 111 is started to perform a waterproof test on the headphone. After the test is completed, the headphone is taken out through the sliding plate 17. Through such a setting, the headphone can be adsorbed by air negative pressure and then moved to the testing table, effectively reducing the damage to the headphone.

[0024] As Figures 1 to 3 shown, a feeding conveyor belt 2 is fixedly connected to the top of the base 1; a placement box 21 is arranged on the top of the feeding conveyor belt 2; a placement groove 22 is opened in the middle of the top of the placement box 21; the shape of the placement groove 22 corresponds to the shape of the headphone; a limiting plate 23 is fixedly connected to the side wall of the feeding conveyor belt 2; when testing the headphone, the headphone to be tested can be placed inside the placement groove 22, and then the placement box 21 is placed on the top of the feeding conveyor belt 2. The placement box 21 will be driven by the feeding conveyor belt 2 to move. After the side wall of the placement box 21 contacts the side wall of the limiting plate 23, the placement box 21 stops moving, so that the headphone reaches the designated position. Through such a setting, when performing a waterproof test on the headphone, the headphone can be transported to the designated position at a fixed angle, which is convenient for cooperating with the air inlet 110 to adsorb and then move the headphone.

[0025] As Figures 1 to 4As shown, a first discharge conveyor belt 3 is fixedly connected to the top of the base 1; a fixed seat 31 is fixedly connected to the top of the base 1; a second servo cylinder 32 is fixedly connected to the top of the fixed seat 31; after the headphones are tested, the headphones are transferred again to the placement groove 22 located at the top of the feeding conveyor belt 2 through the sliding plate 17, and then the tested headphones and the placement box 21 for placing the headphones are pushed to the top of the first discharge conveyor belt 3 by starting the second servo cylinder 32, and then they are driven by the first discharge conveyor belt 3 to be transferred. Through such a setting, after the headphones are tested, the headphones can be taken away, which is convenient for testing the remaining headphones.

[0026] As Figures 1 to 4 As shown, a second discharge conveyor belt 4 is fixedly connected to the top of the base 1; a second air pump 41 is fixedly connected to the top of the fixed seat 31; an air vent pipe 42 is fixedly connected to the air extraction end of the second air pump 41; a connecting plate 43 is fixedly connected to the output end of the second servo cylinder 32; the end of the air vent pipe 42 is fixedly connected to the middle of the side wall of the connecting plate 43; after the waterproof test of the headphones is completed, the headphones are transferred to the placement box 21 at the top of the feeding conveyor belt 2 through the sliding plate 17. If the waterproof test of the headphones is unqualified, the connecting plate 43 is moved by the second servo cylinder 32 so that the side wall of the connecting plate 43 contacts the side wall of the placement box 21, and then the second air pump 41 is started to extract air. At this time, the placement box 21 will be adsorbed by the end of the air vent pipe 42, and then the placement box 21 is pulled to the top of the second discharge conveyor belt 4 by the contraction of the second servo cylinder 32, and the second discharge conveyor belt 4 takes away the headphones with unqualified tests. Through such a setting, the headphones with unqualified tests can be classified separately, which is convenient for subsequent reprocessing.

[0027] As Figures 1 to 4 As shown, a suction cup head 5 is fixedly connected to the side wall of the connecting plate 43; the end of the suction cup head 5 is connected to the end of the air vent pipe 42; during operation, when adsorbing and moving the placement box 21 containing the headphones with unqualified tests, the side wall of the suction cup head 5 contacts the side wall of the placement box 21 to increase the contact area, and then the second air pump 41 extracts air to increase the negative pressure between the side wall of the suction cup head 5 and the side wall of the placement box 21. Through such a setting, when the air vent pipe 42 adsorbs the placement box 21, the adsorption force can be increased, and the situation of the placement box 21 breaking away from the adsorption can be effectively reduced.

[0028] As Figures 1 to 2 As shown, a plurality of fixing blocks 6 are fixedly connected to the middle of the air guide pipe 19; the bottoms of the plurality of fixing blocks 6 are fixedly connected to the top of the sliding plate 17; through such a setting, the shaking of the air in the air guide pipe 19 when being evacuated can be effectively prevented, and further the hindrance and influence of the shaking of the air guide pipe 19 on the operation of the equipment can be prevented.

[0029] As Figures 1 to 2As shown, a plurality of fixing columns 7 are fixedly connected to the top of the base 1; a load-bearing block 71 is fixedly connected to the top of the plurality of fixing columns 7; the load-bearing block 71 is in rotational fit with the rotating circular block 13; during operation, part of the weight of the rotating circular block 13 and the components on the top of the rotating circular block 13 can be transferred to the load-bearing block 71 to bear and transmitted to the base 1 to bear, reducing the force borne by the shaft column of the servo motor 12. Through such a setting, the load borne by the servo motor 12 can be reduced, thereby increasing the service life of the equipment.

[0030] During operation, starting the servo motor 12 can drive the rotating circular block 13 and the components on top of the rotating circular block 13 to rotate. Starting the first servo cylinder 16 can drive the sliding plate 17 to move up and down. With the cooperation of the servo motor 12 and the first servo cylinder 16, the sliding plate 17 can be rotated and moved up and down. First, move the sliding plate 17 above the earphone placed at the designated position so that the air inlet 110 contacts the earphone. Then start the first air pump 18 to pump air. At this time, the earphone will be adsorbed by the air inlet 110. Then, move the earphone to the test platform of the testing machine 111 through the movement of the sliding plate 17. Turn off the first air pump 18 so that the earphone falls into the test slot. Move the sliding plate 17 away and start the testing machine 111 to conduct a waterproof test on the earphone. After the test is completed, take out the earphone through the sliding plate 17. With such a setting, the earphone can be adsorbed by air negative pressure and then moved to the test bench, effectively reducing the damage to the earphone. When testing the earphone, the earphone to be tested can be placed inside the placement slot 22, and then the placement box 21 is placed on top of the feeding conveyor belt 2. The placement box 21 will be driven by the feeding conveyor belt 2 to move. After the side wall of the placement box 21 contacts the side wall of the limiting plate 23, the placement box 21 stops moving, making the earphone reach the designated position. With such a setting, when conducting a waterproof test on the earphone, the earphone can be transported to the designated position at a fixed angle, facilitating adsorption and movement in cooperation with the air inlet 110, and completing the automatic feeding of the earphone. After the test of the earphone is completed, transfer the earphone to the inside of the placement slot 22 located on top of the feeding conveyor belt 2 again through the sliding plate 17. Then, start the second servo cylinder 32 to push the tested earphone and the placement box 21 containing the earphone to the top of the first discharge conveyor belt 3, and then the first discharge conveyor belt 3 drives its transfer. With such a setting, after the earphone test is completed, the earphone can be taken away, facilitating the test of the remaining earphones. After the waterproof test of the earphone is completed, transfer the earphone to the placement box 21 on top of the feeding conveyor belt 2 through the sliding plate 17. If the waterproof test of the earphone is unqualified, move the connecting plate 43 through the second servo cylinder 32 so that the side wall of the connecting plate 43 contacts the side wall of the placement box 21. Then start the second air pump 41 to pump air. At this time, the placement box 21 will be adsorbed by the end of the ventilation pipe 42. Then, pull the placement box 21 to the top of the second discharge conveyor belt 4 through the contraction of the second servo cylinder 32, and the second discharge conveyor belt 4 takes away the earphone with unqualified test. With such a setting, the earphones with unqualified tests can be classified separately, facilitating subsequent reprocessing. During operation, when adsorbing and moving the placement box 21 containing the earphone with unqualified test, the side wall of the suction cup head 5 contacts the side wall of the placement box 21, increasing the contact area. Then, the second air pump 41 pumps air, increasing the negative pressure between the suction cup head 5 and the side wall of the placement box 21. With such a setting, when the ventilation pipe 42 adsorbs the placement box 21, the adsorption force can be increased.Effectively reduce the occurrence of the placement box 21 detaching from adsorption. Through the setting of the fixing block 6, it can effectively prevent the shaking generated when the air inside the air duct 19 is evacuated, thereby preventing the shaking of the air duct 19 from hindering and affecting the operation of the device. The partial weight of the rotating circular block 13 and the components on top of the rotating circular block 13 can be transferred to the load-bearing block 71 for bearing and conducted to the base 1 for bearing, reducing the force borne by the shaft column of the servo motor 12. Through such a setting, the load borne by the servo motor 12 can be reduced, thereby increasing the service life of the device.
