Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0029] See Figure 1-Figure 4 The figure shows an automatic testing device for a microphone, comprising a workbench 1, wherein the inner top wall of the workbench 1 is rotatably connected to a rotating disc 2, and the inner top wall of the workbench 1 is provided with a performance testing mechanism 3, a loading mechanism 4, an unloading mechanism 5, and a cache mechanism 6. The performance testing mechanism 3 is used to perform quality testing on the microphone, the loading mechanism 4 is used to transport the microphone to the rotating disc 2, the unloading mechanism 5 is used to remove OK products from the rotating disc 2, and the cache mechanism 6 is used to remove NG products from the rotating disc 2 for caching. The performance testing mechanism 3, the loading mechanism 4, the unloading mechanism 5, and the cache mechanism 6 are all arranged around the outside of the rotating disc 2.

[0030] It should be noted that a battery is fixedly installed on the outer wall of the workbench 1 to provide power for the electric telescopic rod and the cylinder on the workbench 1.

[0031] The microphone workpiece is transported to one side of the rotating disc 2, the telescopic end of the first electric telescopic rod 402 moves downward, the first gripper 403 clamps the microphone, and then the telescopic end of the second electric telescopic rod 404 performs a stretching movement. When the receiving position 7 on the first electric telescopic rod 402 rotates to one side of the first mounting bracket 401, the first electric telescopic rod 402 finally drives the first gripper 403 to be placed on the receiving position 7, and the rotating disc 2 rotates ninety degrees counterclockwise and passes through the inside of the soundproof box 301. The speaker 302 starts to test the microphone. After the test is completed, the rotating disc 2 rotates ninety degrees again. If it is an ok product, the telescopic end of the first cylinder 502 performs a stretching movement, and the second cylinder 503 and the second gripper 504 are moved forward. During transportation, the telescopic end of the second cylinder 503 drives the second gripper 504 to move downward and clamp the OK product, the telescopic end of the first cylinder 502 moves backward, and the second gripper 504 puts the OK product into the discharge port. If it is an NG product, the rotating disc 2 rotates 90 degrees counterclockwise, and the moving device 602 drives the third gripper 603 to clamp the NG product and put it into the receiving frame 605. The cooperation between the above rotating disc 2, performance testing mechanism 3, loading mechanism 4, unloading mechanism 5, and cache mechanism 6 can be well used as a workstation in the full-line automation to achieve seamless connection. Through automated testing, microphone performance testing can be carried out continuously and efficiently without manual intervention, realizing dataization and greatly improving test efficiency.

[0032] See Figure 4 The performance testing mechanism 3 includes a soundproof box 301 , and a speaker 302 is fixedly installed on the inner wall of the soundproof box 301 .

[0033] The soundproof box 301 can effectively isolate external noise and provide a quiet environment for microphone testing, thereby improving the accuracy of the test.

[0034] See Figure 2 The loading mechanism 4 includes a first mounting frame 401, which is fixedly mounted on the top of the workbench 1. A second electric telescopic rod 404 is fixedly mounted on the first mounting frame 401. The telescopic end of the second electric telescopic rod 404 is connected to the first electric telescopic rod 402, and the telescopic end of the first electric telescopic rod 402 is connected to the first grabbing clamp 403.

[0035] The second electric telescopic rod 404 can drive the first electric telescopic rod 402 and the first grabbing clamp 403 to move horizontally above the rotating disc 2, so as to facilitate moving the microphone transmitted from the previous workstation to the top of the rotating disc 2, and cooperate with the first electric telescopic rod 402 and the first grabbing clamp 403 to accurately place the microphone on one of the receiving positions 7.

[0036] See Figure 2The unloading mechanism 5 includes a second mounting frame 501, which is installed on the top of the workbench 1. A first cylinder 502 is fixedly installed on the second mounting frame 501. The telescopic end of the first cylinder 502 is connected to the second cylinder 503, and the telescopic end of the second cylinder 503 is connected to the second gripper 504.

[0037] The first cylinder 502 can move the second cylinder 503 and the second gripper 504 above the rotating disc 2. After the first cylinder 502 grabs the OK product, the second cylinder 503 can easily drive the first cylinder 502 to move up and down, grab the OK product on the rotating disc 2 and put it into the discharge port.

[0038] See Figure 2 The cache mechanism 6 includes a third mounting frame 601, on which a moving device 602 and a material guide plate 604 are provided. A third gripper 603 is fixedly installed on the moving device 602, the material guide plate 604 is provided below the moving device 602, and a material receiving frame 605 is provided below the material guide plate 604.

[0039] The moving device 602 drives the third gripper 603 to move and grip the NG products on the rotating disk 2 and move them to the top of the guide plate 604. Then the third gripper 603 is released, and the NG products slide through the guide plate 604 into the receiving frame 605.

[0040] See Figure 2 A discharge port is provided on the top of the workbench 1 and is arranged between the rotating disc 2 and the second mounting bracket 501 .

[0041] A receiving frame can be set below the discharge port, and the unloading mechanism 5 can drop the OK into the receiving frame through the discharge port, so as to facilitate the centralized collection of OK products.

[0042] See Figure 2-3 A plurality of receiving positions 7 are provided on the rotating disc 2, and the plurality of receiving positions 7 are distributed in a cross shape.

[0043] The cross-distributed receiving position 7 allows a new microphone to reach the test position every time it rotates 90 degrees, thereby improving the continuity of the test. The microphone test station realizes fully automatic testing and separates defective products from good products, achieving microphone precision testing with good quality consistency and avoiding human misjudgment.

[0044] See Figure 2-3 A support frame is provided on the top of the workbench 1, and a material receiving frame 605 is provided on the top of the support frame.

[0045] The support frame supports the material receiving frame 605 so that the receiving interface of the material receiving frame 605 can fit more closely with the lower end of the material guide plate 604. The opening between the material guide plate 604 and the material receiving frame 605 is too large, causing NG products to slide out.

[0046] Working principle: The microphone workpiece is transported to one side of the rotating disc 2, the telescopic end of the first electric telescopic rod 402 moves downward, the first gripper 403 clamps the microphone, and then the telescopic end of the second electric telescopic rod 404 performs a stretching movement. When the receiving position 7 on the first electric telescopic rod 402 rotates to one side of the first mounting bracket 401, the first electric telescopic rod 402 finally drives the first gripper 403 to be placed on the receiving position 7, the rotating disc 2 rotates ninety degrees counterclockwise, passes through the interior of the soundproof box 301, and the speaker 302 starts to test the microphone. After the test is completed, the rotating disc 2 rotates ninety degrees again. If it is an ok product, the telescopic end of the first cylinder 502 performs a stretching movement, and the second cylinder 503 and the second gripper 50 4 is transported forward, the telescopic end of the second cylinder 503 drives the second gripper 504 to move downward and clamp the OK product, the telescopic end of the first cylinder 502 moves backward, and the second gripper 504 puts the OK product into the discharge port. If it is an NG product, the rotating disc 2 rotates 90 degrees counterclockwise, and the moving device 602 drives the third gripper 603 to clamp the NG product and put it into the receiving frame 605. The mutual cooperation of the above rotating disc 2, performance testing mechanism 3, loading mechanism 4, unloading mechanism 5, and cache mechanism 6 can be well used as a workstation in the full-line automation to achieve seamless connection. Through automated testing, microphone performance testing can be carried out continuously and efficiently without manual intervention, realizing dataization and greatly improving test efficiency.
