[0025] like Figures 1 to 4As shown, a durability testing device for automotive buzzers includes a frame 1. A conveying mechanism 2 is provided at the bottom of the inner wall of the frame 1. A mounting base 3 is installed on the surface of the conveying mechanism 2. A placement tray 4 is provided above the mounting base 3. An automatic feeding component 5 for controlling the rotation of the placement tray 4 is provided on the surface of the mounting base 3. A storage slot for storing buzzers is opened on the left side of the top surface of the placement tray 4. A narrow wire groove is opened on the right side of the top surface of the placement tray 4 for storing buzzer wires. A testing mechanism 6 is provided on the right side of the inner wall of the frame 1. The testing mechanism 6 is used to periodically power on and off the buzzer. An automatic inkjet printing component 7 is provided in the middle of the top surface of the frame 1. More specifically, the buzzer is placed in the storage slot, and the wires are neatly arranged inside the wire slot. Then, the conveying mechanism 2 drives the mounting base 3 and the placement tray 4 to move backward, so that the buzzer reaches the position of the testing mechanism 6. The buzzer is connected to the circuit of the testing mechanism 6 by connecting the buzzer wires to the testing mechanism 6. The testing mechanism 6 can periodically power on the buzzer to conduct a durability test. After the test is completed, the surface of the buzzer is sprayed with paint by the automatic inkjet printing component 7 to record the test results. Finally, the conveying mechanism 2 drives the mounting base 3 and the placement tray 4 to move to the rear, and the automatic unloading component 5 controls the placement tray 4 to rotate backward, thereby automatically unloading the buzzer.

[0026] The conveying mechanism 2 includes a mounting shell 201, which is fixedly connected to the bottom of the inner wall of the frame 1. A first motor 202 is fixedly mounted on the front of the mounting shell 201. A threaded rod 203 is fixedly connected to the output end of the first motor 202. A threaded sleeve 204 is threadedly connected to the surface of the threaded rod 203, and the top surface of the threaded sleeve 204 is fixedly connected to the bottom surface of the mounting base 3. The mounting base 3 is slidably connected to the inner wall of the mounting shell 201. It should be noted that when the first motor 202 operates, it drives the threaded rod 203 to rotate. Under the action of the thread, the threaded sleeve 204 will move, thereby moving the mounting base 3 along the inner wall of the mounting shell 201.

[0027] The automatic feeding assembly 5 includes a support rod 501, which is rotatably connected to the surface of the mounting base 3. The top end of the support rod 501 is fixedly connected to the bottom surface of the placement tray 4. A first electric push rod 502 is rotatably mounted on the inner wall of the mounting base 3. The telescopic end of the first electric push rod 502 is hinged to the bottom surface of the placement tray 4. A collection box 503 is fixedly connected to the rear end of the support rod 501. More specifically, when the conveying mechanism 2 controls the mounting base 3 and the placement tray 4 to move to the rearmost side, the first electric push rod 502 drives the placement tray 4 to rotate backward around the support rod 501, causing the buzzer inside the placement tray 4 to slide into the collection box 503, thereby achieving automatic feeding.

[0028] The testing mechanism 6 includes a PLC control module 601, which is fixedly installed on the right side of the inner wall of the frame 1. A connecting wire 605 is fixedly connected to the surface of the PLC control module 601, and a conductive block 604 is fixedly connected to the end of the connecting wire 605. A second electric push rod 602 is fixedly installed on the top of the inner wall of the frame 1. A mounting block 603 is fixedly connected to the telescopic end of the second electric push rod 602, and the mounting block 603 is fixedly connected to the conductive block 604. It should be noted that during the test, the conveying mechanism 2 controls the mounting base 3 and the placement tray 4 to move below the conductive block 604. The second electric push rod 602 operates, driving the mounting block 603 and the conductive block 604 to descend, so that the conductive block 604 contacts the exposed part of the buzzer wire end, thereby connecting the buzzer to the PLC control module 601 circuit. The PLC control module 601 achieves precise control of the circuit on and off through programming. Users can write programs as needed to set the time and number of power on and off, thereby realizing the durability test of the car buzzer. The specific circuit principle is existing technology and will not be described in detail here.

[0029] The automatic coding assembly 7 includes an ink cartridge 701, which is fixedly installed on the top surface of the frame 1. A printhead 702 is fixedly installed on the bottom of the ink cartridge 701, and a sound sensor 8 is fixedly installed on the top surface of the frame 1. More specifically, during the periodic operation of the buzzer controlled by the testing mechanism 6, the sound sensor 8 detects whether sound is generated. If no sound is detected from the buzzer multiple times consecutively, the product is judged to be unqualified. The surface of the buzzer is then sprayed with ink by the ink cartridge 701 and the printhead 702. The sprayed content includes the test time and the word "unqualified". During the entire testing process of the testing mechanism 6, if the sound sensor 8 can detect sound, the test time and the word "qualified" are sprayed on the surface of the buzzer.

[0030] Support legs are fixedly connected to the four corners of the bottom surface of frame 1, and shock-absorbing pads are fixedly connected to the bottom of each support leg. It should be noted that by setting up support legs and shock-absorbing pads, frame 1 is stably supported, preventing the entire device from vibrating.

[0031] In summary: The buzzer is placed in the storage slot, and the wires are neatly arranged inside the wire slot. Then, the conveying mechanism 2 drives the mounting base 3 and the placement tray 4 to move backward, allowing the buzzer to reach the testing mechanism 6. The buzzer is then connected to the circuit of the testing mechanism 6 via the buzzer's wires. The testing mechanism 6 allows for periodic power-on operation of the buzzer to conduct a durability test. After the test, the buzzer surface is coated with inkjet printing by the automatic inkjet printing component 7 to record the test results. Finally, the conveying mechanism 2 drives the mounting base 3 and the placement tray 4 to move to the rear, and the automatic unloading component 5 controls the placement tray 4 to rotate backward, thus automatically unloading the buzzer. In use, this system facilitates automated durability testing of automotive buzzers. Operators only need to place the buzzer into the device, making operation easier and less labor-intensive, and improving testing efficiency.
