Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of automated testing, in particular to multi-station automated testing equipment. Background Art
[0002] Wireless headphones are a type of headphones that use radio waves instead of wires. Microphones, speakers and other components are integrated on a flexible circuit board. Due to quality requirements, the frequency response and microphone effect tests are required after the flexible circuit boards used for wireless headphones are produced.
[0003] However, in order to protect the sound holes from being contaminated by dust, a protective film will be attached to the speaker after the flexible circuit board is produced. During the testing phase, this protective film needs to be torn off, and after the test is completed, the protective film needs to be re-attached. The increase in the steps of tearing off and attaching the film leads to an increase in the steps of the testing phase, and the flexible circuit board is small in size, which makes it inconvenient to operate. In addition, the transportation of the flexible circuit board after the speaker film is torn off between testing equipment increases the risk of dust contaminating the sound holes. These problems have led to the poor efficiency and accuracy of existing testing equipment in testing flexible circuit boards.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The present invention integrates the functions of loading, film tearing, frequency response testing, film application and unloading into one device. After the material tray containing the product to be tested is placed from the material inlet, the whole process is unmanned through the robot assembly, synchronous belt transmission system and intelligent control module, which significantly shortens the test cycle. The structure between the mechanisms is compact and the layout is reasonable, which improves the efficiency of the test.
[0015] 2. The turntable divider of the present invention is combined with a multi-station design to complete the film tearing and testing of multiple products in parallel within the same cycle. It is more efficient than traditional single-station equipment and is particularly suitable for production lines for large-scale wireless headset flexible circuit boards.
[0016] 3. The present invention ensures the position accuracy of the product to be tested during transportation and testing by scanning the code positioning component. Combined with the visual positioning of the manipulator, the material picking error can be controlled within a very small range, avoiding test failure caused by position offset. It is especially suitable for high-precision testing scenarios of micro flexible circuit boards.
[0017] 4. The present invention's testing process is conducted within a relatively enclosed machine, coupled with a pneumatic dust removal system to effectively isolate external dust from interfering with the sound holes and the testing process. After film removal, the product under test is directly tested in a shielded environment, avoiding sensitivity deviations caused by dust adhesion during traditional manual handling, thereby improving the reliability of test results.
[0018] 5. The present invention adopts a modular design. For example, the upper and lower material flow channels, test table and film assembly can be independently disassembled or replaced. For example, by adjusting the size of the material tray trough or replacing the probe module, flexible circuit boards of different specifications can be quickly adapted to meet the needs of co-linear testing of multiple models of products and reduce the cost of repeated investment in equipment.
[0019] 6. The present invention uses sample products pre-placed in the sample carrier. The equipment can regularly use a robot to grab the sample products to perform full-process testing, compare the preset parameters to determine the equipment status, and promptly detect probe wear or sensor drift problems, thereby ensuring long-term test consistency and reducing product batch defect rate.

The experimental methods in the following examples, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following examples, unless otherwise specified, can be obtained from commercial channels.
[0040] Example: Figure 1 、 Figure 2 and Figure 3As shown, the multi-station automated testing equipment includes an equipment frame 10. The bottom of the equipment frame 10 is provided with supporting feet and casters. The surface of the equipment frame 10 is connected to a number of panels and covers for shielding the internal equipment. A control computer is also provided on the panel. The upper cover is also provided with a wind dust removal device 11. The wind dust removal device 11 is a well-known technology and will not be described in detail here. Feeding areas are provided on both sides of the interior of the equipment frame 10, and a testing area is provided in the middle of the interior of the equipment frame 10. The feeding area and the testing area are connected to the equipment frame 10. There are several manipulator components 12 for transporting the product to be tested.

Two groups of loading and unloading flow channels 14 are respectively provided on the front and rear sides of the loading and unloading platform 13. The two groups of loading and unloading flow channels 14 are arranged front and back relative to each other. The product to be tested can be loaded and unloaded from the front and back positions respectively. The loading and unloading flow channels 14 include flow channel columns 15. The flow channel columns 15 are connected to the bottom surface of the loading and unloading platform 13. There are holes on the flow channel columns 15. The material tray support frame 16 is slidably connected to the material tray support frame 16 through a sliding bearing. A material tray 17 is supported on the material tray support frame 16. A plurality of material troughs 18 for placing the product to be tested are evenly opened on the surface of the material tray 17. The bottom end of the flow channel column 15 is connected to the upper and lower material racks 19. The upper and lower material racks 13 are provided with openings for taking and placing materials at positions corresponding to the upper and lower material racks 19. The upper and lower material racks 19 are rotatably installed with a screw rod 20 between the two flow channel columns 15. A threaded hole is opened on the material tray support frame 16 and is threadedly connected to the screw rod 20. The upper and lower material racks 19 A lifting motor 21 for driving the screw rod 20 to rotate is installed on it. The drive shaft of the lifting motor 21 is connected to the screw rod 20 through a synchronous belt assembly. The synchronous belt assembly is an existing well-known technology. Here, it includes two synchronous wheels, which are respectively connected to the screw rod 20 and the drive shaft of the lifting motor 21.

The cover plate is provided with a material port for loading the tray at the position corresponding to the upper and lower material racks 19.
[0041] Specifically, a number of products to be tested are placed in the material tray 17 in a manner that is adapted to the material trough 18, and then placed on the material tray support frame 16 from the material port. The lifting motor 21 drives the screw rod 20 to rotate, and the material tray support frame 16 threadedly connected to the screw rod 20 rises along the flow channel column 15 to the loading and unloading platform 13, so that the robot assembly 12 can take the material to the test area for testing.

[0043] Specifically, after the material tray 17 rises to the surface of the loading and unloading table 13 along with the material tray support frame 16, the leveling cylinder 30 controls the push plate 31 to extend, applies a pushing force to the length and width directions of the material tray 17, and clamps and fixes it, so that the position of the material tray 17 during use is accurate and stable. Through the linkage design of the flow channel column 15 and the screw rod 20 lifting system, combined with the three-dimensional shaping of the material tray 17 by the leveling cylinder 30, the automatic leveling and precise positioning of the material tray 17 are achieved.
