Description

Technical Field

[0001] This utility model relates to the field of microphone function detection technology, specifically to a microphone function detection device. Background Technology

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals, the opposite of a speaker (electricity → sound). It represents one of the two terminals of a sound device: the microphone is the input, and the speaker is the output. Also known as a microphone core, microphone, or transducer, microphones require sensitivity testing during manufacturing.

[0003] Currently, the testing of existing microphones is all done manually, with a low degree of automation in the testing process. This increases the labor intensity of microphone testing and reduces work efficiency. Moreover, because the entire testing process requires manual operation, it is easy to miss some microphones and damage them during testing, thereby reducing the yield rate. Utility Model Content

[0004] The purpose of this invention is to provide a microphone function detection device to solve the problems mentioned in the background art, such as low efficiency of manual detection and the easy occurrence of missed detections or damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microphone function testing device, comprising a frame, a touch screen mounted on one side of the frame surface for controlling the entire device; a feeding cavity provided on the surface of the frame, and a feeding mechanism installed inside the feeding cavity for feeding a whole board of microphone products; a testing mechanism provided on one side of the feeding mechanism for testing the whole board of microphone products; and a picking mechanism mounted on the surface of the frame and on one side of the testing mechanism, capable of transferring products from the feeding mechanism to the testing mechanism, and simultaneously unloading products tested from the testing mechanism.

[0006] Preferably, a precision tester is fixed on the surface of the frame and on one side of the touch screen, and the precision tester is electrically connected to the touch screen; an alarm is installed at the top of the frame and is electrically connected to the touch screen.

[0007] Preferably, a display is mounted on the surface of the top of the rack for displaying information during testing, and the display is electrically connected to a touch screen.

[0008] Preferably, the feeding mechanism includes a lifting module and a feeding clip, and the feeding clip is inserted into the surface of the frame for placing products.

[0009] Preferably, the lifting module is installed inside the feeding cavity via a support plate, and the lifting module is used to push the product inside the feeding magazine to rise.

[0010] Preferably, the testing mechanism includes a product carrier plate, a cylinder fixture, a push cylinder, and a cylinder pressure plate fixture. A U-shaped frame is mounted on the surface of the frame, and the product carrier plate is slidably connected to the surface of the U-shaped frame. A push cylinder is mounted on one side of the U-shaped frame and is fixedly connected to the product carrier plate.

[0011] Preferably, a cylinder fixture is installed on the surface of the frame and below the U-shaped frame, and the cylinder fixture is electrically connected to the precision testing instrument; a cylinder pressure plate fixture is installed on the top of the U-shaped frame, and the cylinder pressure plate fixture and the cylinder fixture work together for the testing of the product.

[0012] Preferably, the material handling mechanism includes a robotic arm and cylinder grippers. The robotic arm is fixed to the surface of the frame by a bracket, and three sets of cylinder grippers are installed on the sliding end of the robotic arm. The cylinder grippers are used for clamping and placing products.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the microphone function testing device is implemented, the product fixture with the microphone product is placed into the loading magazine. The lifting module drives the product fixture in the loading magazine to rise sequentially. After rising to the position, the robotic arm drives the cylinder gripper to descend and pick up the microphone product. The robotic arm then moves the microphone product on the product carrier plate. The cylinder drives the microphone product on the product carrier plate to move directly below the cylinder fixture and cylinder pressure plate fixture. Then, the cylinder fixture and cylinder pressure plate fixture, together with a precision testing instrument, are used to test the sensitivity of the product. This utility model improves the automation level of microphone testing by setting up a loading mechanism, a testing mechanism, and a conveying mechanism. No manual operation is required during the testing process, thus reducing the labor intensity of microphone testing and improving the efficiency of short-pair microphone testing. Moreover, since the entire testing process is completed automatically by the machine without manual operation, there will be no missed detections or human-caused damage during testing, thereby increasing the yield rate during testing.

A precision tester 12 is fixed on the surface of the frame 1 and located on one side of the touchscreen 11. The precision tester 12 is electrically connected to the touchscreen 11 and is an electroacoustic comprehensive tester, model HS6123. An alarm 14 is mounted on the top of the frame 1 and is electrically connected to the touchscreen 11. A display 13 is mounted on the top surface of the frame 1 and is used for displaying information during testing. The machine operates, and the display 13 is electrically connected to the touch screen 11; the surface of the frame 1 is provided with a feeding cavity 16, and a feeding mechanism 2 is installed inside the feeding cavity 16. The feeding mechanism 2 is used for feeding a whole board of microphone products. The feeding mechanism 2 includes a lifting module 21 and a feeding clip 22. The feeding clip 22 is inserted into the surface of the frame 1. The feeding clip 22 is used for placing products. The lifting module 21 is installed inside the feeding cavity 16 through a support plate. The lifting module 21 is used to push the products inside the feeding clip 22 to rise.

[0022] During implementation, the product fixture with the product is placed into the loading magazine 22, and the product fixture in the loading magazine 22 is raised sequentially by the lifting module 21.

[0023] Furthermore, such as Figure 2 as well as Figure 4 As shown, a detection mechanism 3 is provided on one side of the feeding mechanism 2. The detection mechanism 3 is used for the detection of the entire panel of microphone products. The detection mechanism 3 includes a product carrier plate 31, a cylinder fixture 32, a push cylinder 33, and a cylinder pressure plate fixture 34. A U-shaped frame 15 is installed on the surface of the frame 1. The product carrier plate 31 is slidably connected to the surface of the U-shaped frame 15. A push cylinder 33 is installed on one side of the U-shaped frame 15 and is fixedly connected to the product carrier plate 31. A cylinder fixture 32 is installed on the surface of the frame 1 and below the U-shaped frame 15. The cylinder fixture 32 is electrically connected to the precision tester 12. A cylinder pressure plate fixture 34 is installed on the top of the U-shaped frame 15. The cylinder pressure plate fixture 34 and the cylinder fixture 32 cooperate to detect the product.

[0024] During implementation, the product carrier plate 31 is moved to the position directly below the cylinder fixture 32 and the cylinder pressure plate fixture 34 by pushing the cylinder 33. Then, the product is tested by the cylinder fixture 32 and the cylinder pressure plate fixture 34 in conjunction with the precision tester 12. The test results are displayed on the display 13. After the test, the product is picked up by the cylinder gripper 42.

The robot arm 41 then moves the microphone product onto the microphone product carrier plate 31. The cylinder 33 drives the microphone product on the product carrier plate 31 to move directly below the cylinder fixture 32 and the cylinder pressure plate fixture 34. Then, the cylinder fixture 32 and the cylinder pressure plate fixture 34, together with the precision tester 12, are used to perform sensitivity testing on the product. The test results are displayed on the display 13. After the test, the cylinder gripper 42 descends to grab the product, and the robot arm 41 drives the cylinder gripper 42 to complete the unloading operation.
