[0031] In order to meet the needs of users, each wireless earphone box needs to undergo rigorous functional tests before leaving the factory to verify whether it can operate normally and ensure that the earphone charging box has stable quality. Currently, most earphone box tests still use the traditional test mode of manual plus auxiliary tools, which has a low degree of automation and takes a long time for manual intervention, affecting the efficiency of earphone box testing.

[0032] To solve the above problems, please refer to Figures 1 to 6The utility model proposes an earphone box detection device 1000, including a frame 1, a plurality of test boxes 2 and a material transfer mechanism 3, each test box 2 is arranged at intervals on the frame 1, an installation cavity is formed in the test box 2, and at least one test component 21 is arranged in the installation cavity for testing the earphone box 200; the material transfer mechanism 3 includes a conveyor belt assembly 31 and a material transfer robot 32, the conveyor belt assembly 31 is arranged on one side of the frame 1, the material transfer robot 32 is arranged on the frame 1, each test box 2 is arranged around the material transfer robot 32, and the material transfer robot 32 is used to transfer the earphone box 200 between the test box 2 and the conveyor belt assembly 31.

[0033] The technical solution of the utility model is to surround a plurality of test boxes 2 on a frame 1, and to transfer the earphone box 200 from a conveyor belt assembly 31 to the test box 2 for testing by a material transfer robot 32, and to take the earphone box 200 out of the test box 2 after the test and transfer it to the conveyor belt for inspection, thereby avoiding errors in manual inspection of the earphone box 200, improving the efficiency of the inspection of the earphone box 200, and reducing the labor intensity of manual inspection.

[0034] In an optional embodiment, in order to realize automatic detection of the earphone box 200, the test assembly 21 includes a mounting fixture 211, a test frame 212 and a first driving member 213. The mounting fixture 211 is arranged in the mounting cavity, and the mounting fixture 211 is formed with a mounting groove for accommodating the earphone box 200. The test frame 212 is arranged above the mounting fixture 211. A plurality of test probes 2121 are connected to the test frame 212. The output end of the first driving member 213 is connected to the test frame 212 to drive the test frame 212 to move up and down in the vertical direction so that the test probes 2121 are inserted into the earphone box 200 in the mounting groove. Please refer to Figures 1 to 4A mounting groove is formed on the mounting fixture 211 for accommodating the earphone box 200. The earphone box 200 to be tested is transferred from the conveyor belt assembly 31 to the mounting fixture 211 by the material transfer robot 32. It should be noted that during this process, the earphone box 200 is in an open state. After the earphone box 200 is placed in the mounting fixture 211, the test frame 212 is driven to descend by the first driving member 213 so that the test probe 2121 is correspondingly inserted into the earphone box 200 for testing. In this embodiment, a plurality of test probes 2121 are connected to the test frame 212, and each test probe 2121 is detachably connected to the test frame 212 to facilitate adjustment of the installation height of the test probe 2121 on the test frame 212. In addition, a test plug is also connected to the test stand 212. When the test stand 212 descends, the test plug moves down accordingly with the test stand 212. When the position of the test plug moves to a position flush with the type-c interface on the side of the earphone box 200, the test plug is inserted into the type-c interface to test the interface of the earphone box 200. Optionally, in order to buffer the test plug, an elastic member is provided on the side of the test plug facing away from the earphone box 200 to buffer when the test plug moves down and is inserted, thereby ensuring the stability of the earphone box 200 detection.

[0035] In an optional embodiment, in order to fix the earphone box 200 during testing, first pressing blocks 2122 are further provided on opposite sides of the bottom of the test frame 212. The first pressing blocks 2122 are arranged facing the edge of the installation slot.

Please refer to Figures 1 to 4A through hole is opened on the side of the test box 2 to connect the installation cavity with the external space. The slide rail 214 is installed in the installation cavity in the horizontal direction and extends outward. The installation fixture 211 is slidably installed on the slide rail 214. The second driving member under the slide rail 214 drives the installation fixture 211 to reciprocate along the extension direction of the slide rail 214, so as to transport the earphone box 200 from the outside of the test box 2 to the installation cavity for testing by the test frame 212, thereby realizing automatic loading of the earphone box 200.

[0037] Furthermore, in order to ensure the positioning accuracy of the installation fixture 211 on the slide rail 214, the test assembly 21 also includes a limiter 215, which is arranged on both sides of the slide rail 214. The two ends of the installation fixture 211 extend outward to form a contact portion 2111, and the limiter 215 abuts against the contact portion 2111. Please refer to Figure 3 , there are limiters 215 on both sides of the extension direction of the slide rail 214. When the second driving member drives the installation fixture 211 to move into the installation cavity of the test box 2, when the installation fixture 211 moves to the contact parts 2111 at the left and right ends and contacts the limiters 215, the limiters 215 resist the installation fixture 211 to limit its continued inward movement, thereby ensuring that the installation fixture 211 is docked at the correct position, so as to ensure that the test piece can be accurately inserted into the earphone box 200 to be tested when it descends, and ensure the reliability of the test. Optionally, a pressure sensor or a contact sensor can be set on the side where the limiter 215 abuts against the contact part 2111, and the sensor is electrically connected to the second driving member. When the limiter 215 contacts the contact part 2111, the sensor is squeezed and sends an electrical signal to the corresponding controller, and the controller sends a control signal to control the second driving member to stop, so that the installation fixture 211 accurately stops under the test frame 212 for subsequent testing.

[0038] In an optional embodiment, in order to facilitate the detection of the charging port of the earphone box 200, the test component 21 also includes a second pressure block 2123. The second pressure block 2123 is arranged on the adjacent side of the test frame 212 relative to the first pressure block 2122. The mounting fixture 211 forms a avoidance groove corresponding to the charging port of the earphone box 200. The second pressure block 2123 is formed with a avoidance hole 2123a at one end close to the mounting fixture 211. The second pressure block 2123 can be inserted into the avoidance groove, and the avoidance hole 2123a is connected to the charging port to expose the charging port. The test component 21 also includes a plug and a third drive member 216. The third drive member 216 is arranged on the frame 1. The output end of the third drive member 216 is connected to the plug to drive the plug to pass through the avoidance hole 2123a in the horizontal direction to be inserted into the charging port. Please refer to Figure 3 and Figure 4The second pressing block 2123 is arranged on the adjacent side of the test frame 212 relative to the first pressing block 2122, and corresponds to the avoidance groove on the installation fixture 211. When the test frame 212 descends, the second pressing block 2123 cooperates with the avoidance groove and presses the installation fixture 211 as the test frame 212 moves. The avoidance hole 2123a on the second pressing block 2123 is connected to the charging port on the earphone box 200 to make it exposed, so that the third driving member 216 can drive the plug to pass through the avoidance hole 2123a and be plugged into the charging port, thereby checking whether the charging port of the earphone box 200 can be used normally and ensuring the product quality of the earphone box 200.

[0039] In an optional embodiment, in order to improve the transfer efficiency of the material transfer robot 32, the material transfer robot 32 includes a base 321 and a clamping claw assembly 322, the base 321 is installed on the frame 1, the clamping claw assembly 322 is rotatably installed on the base 321, and the clamping claw assembly 322 includes four clamping claws arranged at intervals. Figure 1 , Figure 5 and Figure 6 , four clamping claws are arranged on the base 321 in pairs, so that when transferring the earphone box 200, one movement of the material transfer manipulator 32 can meet the loading or unloading of two groups of test components 21 in a test box 2, thereby improving the efficiency of loading and unloading. When the material transfer manipulator 32 grabs the earphone box 200, the left and right clamping blocks on the clamping claws are close to each other to clamp the left and right sides of the earphone box 200. Optionally, in order to ensure the stability of clamping, the end surface of the clamping block in contact with the earphone box 200 is set to an arc surface that is adapted to the earphone box 200 to increase the contact area between the clamping block and the earphone box 200 and ensure the stability of clamping. In addition, an elastic buffer layer can be set on the end surface of the clamping block in contact with the earphone box 200 to reduce the pressure of the clamping block on the earphone box 200 and avoid damage to the earphone box 200 due to excessive clamping force.

[0040] In an optional embodiment, in order to distinguish good and bad earphone boxes 200 after inspection, the conveyor assembly 31 includes a carrier line 311, a product belt line and a bad belt line 312. The carrier line 311 and the bad belt line 312 are arranged on opposite sides of the material transfer robot 32, and the product belt line is arranged on the side of the bad belt line 312 away from the material transfer robot 32. Please refer to Figure 1 , Figure 5 and Figure 6 The carrier line 311 and the defective product belt line 312 are respectively arranged on both sides of the material transfer robot 32. The material transfer robot 32 grabs the earphone box 200 to be tested from the carrier line 311 to the test box 2. After the inspection of the earphone box 200 is completed, the defective products are grabbed by the material transfer robot 32 and put on the defective product belt line 312, and the good products are grabbed on the product belt line. The good products and defective products are grabbed on two different production lines for distinction to avoid confusion between the two.

[0041] Furthermore, in order to facilitate the positioning of the earphone box 200 when the material transfer robot 32 grabs it on the carrier line 311, a plurality of carriers are arranged on the carrier line 311, and each carrier is evenly distributed on the carrier line 311.
