Description

Technical Field

[0001] This invention relates to the field of headphone charging case testing technology, specifically to an automated testing device and method for headphone charging cases. Background Technology

[0002] An earphone charging case stores and charges wireless earphones. It typically includes a bottom and a lid that closes to the bottom. The bottom has at least one earphone storage slot on the side facing the lid, where the earphones protrude from the slot. The lid has at least one earphone retaining groove on the side facing the bottom, aligned with the earphone storage slot. This groove allows the earphones to be stored together with the earphone storage slot when the lid is closed. With societal progress, the wireless earphone industry is booming, and people demand longer earphone usage times. However, earphones are small, resulting in small batteries and potential power shortages. Against this backdrop, many manufacturers have designed portable earphone charging cases.

[0003] In the production process of earphone charging cases, multiple tests are required, including the flip-top function, USB interface durability, charging contact conductivity, and LED indicator lights. In existing technologies, these tests are mostly conducted manually or semi-automatically. Operators manually place the charging case on a fixture, sequentially perform operations such as opening and closing the lid, plugging and unplugging the USB, placing the test earphones, and observing the indicator lights, and record the test results. Because each testing step is scattered and relies on manual completion, not only is the single testing cycle long, making it difficult to match the production rhythm of modern production lines, but the test results are also easily affected by the subjective factors and fatigue of the operators, resulting in inconsistent testing standards, insufficient product quality control stability, and thus limiting production efficiency. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the prior art, which mostly uses manual or semi-automatic methods to conduct the above-mentioned tests. The operator manually places the charging box on the fixture, performs operations such as opening and closing the cover, plugging and unplugging the USB, placing the test earphone, and observing the indicator light, and records the test results. Because each test step is scattered and depends on manual completion by personnel, not only is the single test cycle long and difficult to match the production rhythm of modern production lines, but the test results are also easily affected by the subjective factors and fatigue of the operators, resulting in inconsistent test standards, insufficient product quality control stability, and thus limiting production efficiency.

By integrating multiple scattered testing procedures into one station and automatically completing them sequentially, the testing efficiency is greatly improved.

[0026] like Figure 2 As shown, the carrier assembly 200 includes a support base 201, which is fixedly connected to the top of the base plate 100. The carrier 202 is fixedly connected to the top of the carrier 202. The top of the carrier 202 has a placement groove 203 that matches the outer contour of the earphone charging case. The placement groove 203 is used to accommodate the earphone charging case. A first suction head 204 is disposed on the inner bottom wall of the placement groove 203. After the earphone charging case is placed into the placement groove 203, the first suction head 204 activates to generate negative pressure, thereby firmly adsorbing and fixing the earphone charging case. This achieves rapid, accurate positioning and firm fixation of the earphone charging case, avoiding test failures or inaccurate results caused by displacement of the earphone charging case during testing.

[0027] like Figure 2 As shown, the vehicle 202 is also equipped with a detection device, which is a position sensor. After the earphone charging case is placed in the placement slot 203, the position sensor can immediately detect the presence of the earphone charging case.

[0028] like Figure 3 As shown, the flip-top assembly 300 includes a rotary cylinder 301, which is fixedly connected to the top of the base plate 100. A first push cylinder 302 is fixedly connected to the output end of the rotary cylinder 301, and a connecting plate 303 is fixedly connected to the output end of the first push cylinder 302. A contour block 304 is fixedly connected to the connecting plate 303.

The rotary cylinder 301 drives the rotation, the first push cylinder 302 provides the pushing force to control the linear movement of the contour block 304, and the second suction head 305 adsorbs the lid of the earphone charging case for flip-top operation. This flip-top assembly 300, by driving the contour block 304 with the first push cylinder 302, can simulate the opening and closing action of a human hand on the earphone charging case lid, thus automating the flip-top testing process.

[0029] like Figure 4As shown, the USB plug-in / plug-out test assembly 400 includes a second push cylinder 401, which is fixedly connected to the top of the base plate 100. A movable plate 402 is fixedly connected to the output end of the second push cylinder 401. A mounting plate 403 is fixedly connected to the top of the movable plate 402. A floating block 404 is fixedly connected to the front end of the mounting plate 403. A plastic test head 405 is fixedly connected to the top of the floating block 404. The second push cylinder 401 is used to drive the movable plate 402 and the mounting plate 403, so that the test head 405 is inserted into the USB interface of the headphone charging case to perform a USB plug-in / plug-out test.

[0030] like Figure 4 As shown, the top of the second push cylinder 401 is equipped with a slide rail, and the mounting plate 403 is L-shaped. A slider is fixedly connected to the inner wall of the mounting plate 403, and the slider is slidably connected to the slide rail. When the second push cylinder 401 is driven, the slider slides along the slide rail, ensuring that the test head 405 is precisely aligned with the USB interface.

[0031] like Figure 5 As shown, the probe assembly 500 includes a mounting base 501, which is fixedly connected to the top of the base plate 100. A rodless cylinder 502 is fixedly connected inside the mounting base 501. A fixing plate 503 is fixedly connected to the output end of the rodless cylinder 502. A fixing block 504 is fixedly connected to the top of the fixing plate 503. A probe 505 and a magnetic switch 506 are fixedly connected to the side of the fixing block 504. The rodless cylinder 502 is used to drive the probe 505 to move and contact the contacts of the earphone charging case to simulate the earphone insertion test. The magnetic switch 506 is used to detect the earphone magnet in the earphone charging case. During the simulated earphone insertion test, the rodless cylinder 502 drives the probe 505 forward to reliably contact the metal contacts inside the earphone charging case for charging the earphones, performing an electrical performance test. At the same time, the magnetic switch 506 is used to detect the presence of the magnet inside the charging case for attracting the earphones.

[0032] like Figure 6 and Figure 7As shown, the LED testing assembly 600 includes a gantry 601, which is fixedly connected to the top of the base plate 100. A mounting bracket 602 is fixedly connected to the gantry 601. A pressing cylinder 603 is fixedly connected to the side of the mounting bracket 602. A pressing plate 604 is fixedly connected to the output end of the pressing cylinder 603. A mounting block 605 is fixedly connected to the pressing plate 604. An LED light-collecting column 606 is fixedly connected to the middle of the mounting block 605. The pressing cylinder 603 is used to drive the LED light-collecting column 606 to move downward. The LED light-collecting column 606 is used to collect the LED light signal of the earphone charging case and is configured to connect to an external LED analyzer to test the color and brightness of the indicator light. During LED testing, the downward cylinder 603 drives the LED light-collecting column 606 to move downward, so that its end is close to or slightly in contact with the indicator light window of the charging box. The LED light-collecting column 606 transmits the light signal emitted by the indicator light to the external LED analyzer. In this way, the optical parameters such as the color, brightness and flashing frequency of the indicator light can be analyzed, completely replacing the subjective judgment of the human eye and improving the level of optical performance testing of the charging box.

[0033] like Figure 6 and Figure 7 As shown, flexible pressure heads 607 are embedded on both sides of the lower pressure plate 604. When the LED light-collecting column 606 moves down into place, the lower pressure cylinder 603 continues to drive, and the pressure head 607 can press firmly onto the outer shell of the charging box.

[0034] During testing, the operator first places the earphone charging case to be tested into the placement slot 203 of the carrier assembly 200. After the position sensor in the placement slot 203 detects that the product is in place, the first suction head 204 is activated to generate negative pressure to suction and fix the charging case onto the carrier 202. After fixing, the rotary cylinder 301 drives the first push cylinder 302 and the contour block 304 to rotate to an angle that matches the charging case lid. Then, the first push cylinder 302 pushes the contour block 304 forward, so that the second suction head 305 contacts and suctions the lid. Finally, the rotary cylinder 301 rotates in the opposite direction to open the lid smoothly, completing the flip-top test. Next, the second push cylinder 401 drives the test head 405 to move linearly along the slide rail guide through the moving plate 402 and the mounting plate 403, inserts it into the USB interface of the charging box, and then withdraws it. This insertion and removal durability test is repeated. With the flip cover open, the rodless cylinder 502 drives the fixing block 504 and the probe 505 to move forward, so that the probe 505 contacts the charging contacts inside the charging case to test the electrical performance of the charging circuit. At the same time, the magnetic switch 506 detects the magnet inside the charging case used to attract the earphones. Finally, the lowering cylinder 603 drives the lowering plate 604 to move downward, so that the flexible pressure heads 607 on both sides of the lowering plate 604 press against the charging box shell, ensuring the absolute stability of the product during the test. At the same time, the LED light-collecting column 606 is aligned with the indicator light window, and the collected light signal is transmitted to the external LED analyzer to analyze the optical parameters such as the brightness and color of the indicator light.

[0035] This invention integrates multiple testing functional modules into one unit, achieving full automation of the entire process from opening the headphone charging case, plugging and unplugging USB, electrical connection and optical testing, greatly improving testing efficiency.
