Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board performance testing technology, and in particular to a flexible circuit board side insertion force monitoring module. Background Technology

[0002] Flexible printed circuit boards (FPCs), commonly known in the industry, are printed circuit boards made from flexible insulating substrates (mainly polyimide or polyester film). They possess many advantages that rigid printed circuit boards lack, such as the ability to be freely bent, rolled, and folded. Utilizing these characteristics, FPCs can significantly reduce the size of electronic products, making them suitable for the development of high-density, miniaturized, and highly reliable electronic products. Therefore, they are widely used in aerospace, military, mobile communications, laptops, computer peripherals, and other fields and products. During the manufacturing process of FPCs, performance testing is required. This is typically done by connecting testing equipment to the FPC via connectors and performing functional tests using testing software systems. Traditionally, this involves manually plugging and unplugging the testing equipment to the FPC, a method that is inefficient and labor-intensive, failing to meet the modern demands for flexible circuit board production. Existing automated testing equipment uses motors and other drive components to automatically connect connectors to flexible circuit boards, thereby improving production efficiency. However, the automated equipment on the market cannot provide real-time feedback on the actual pressure value when the connector is inserted or removed, and cannot monitor whether the connector is successfully connected. This can easily lead to problems such as connector misalignment damaging the equipment or the flexible circuit board. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a flexible circuit board side insertion force monitoring module that can monitor the real-time insertion and removal pressure value at the connector of a flexible circuit board, thereby ensuring that the side insertion mechanism of the monitoring device will not damage the product.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes two sets of slide rails symmetrically arranged and a track connecting plate slidably connected to the slide rails. The front end of the track connecting plate is provided with a side plug mounting groove, and a quick-release assembly is provided in the side plug mounting groove. The side plug can be detachably installed on the quick-release assembly. A sensor cover plate is also connected to the rear end of the track connecting plate through several sliding limit posts. A pressure sensor is built into the sensor cover plate. A buffer spring is also provided on the track connecting plate. The buffer spring abuts against the pressure sensor. The pressure sensor is electrically connected to an external detection device.

[0005] Furthermore, the track connecting plate is composed of a first connecting plate and a second connecting plate that are slidably connected to the two sets of slide rails respectively. The side plug mounting slot is opened at the front end of the first connecting plate. The sensor cover is fixedly connected to the rear end of the second connecting plate. The front ends of a plurality of sliding limiting posts are threaded to the first connecting plate and the ends are slidably connected to the second connecting plate. The front end of the buffer spring is threaded to the first connecting plate and the end is fixedly connected to the sensor cover at the position corresponding to the pressure sensor.

[0006] Furthermore, a sliding step hole adapted to the sliding limiting post is provided in the second connecting plate. The front section of the sliding step hole is adapted to the sliding limiting post, and the rear section is larger than the front section. A limiting ring is threaded to the end of the sliding limiting post, and the size of the limiting ring is adapted to the rear section of the sliding step hole.

[0007] Furthermore, the quick-release assembly includes a mounting plate, an integrally formed plug-in section disposed at the lower end of the mounting plate, and a pressing ball disposed within the plug-in section. The pressing ball is connected to the inner sidewall of the plug-in section by a spring and extends outward to the outside of the plug-in section. A slot adapted to the plug-in section is also provided in the side plug mounting groove, and a mounting arc surface adapted to the pressing ball is provided in the slot.

[0008] Finally, a quick-release hole is also provided on the first connecting plate at the position corresponding to the mounting arc surface.

[0009] Compared with existing technologies, the advantages of this invention are as follows: This invention connects to an external driving component via the track connecting plate, driving the side plug installed in the side plug mounting slot to slide along the slide rail towards the flexible circuit board under test and insert the side plug into the flexible circuit board. Through the cooperation of the pressure sensor and the buffer spring located within the sensor cover, the real-time pressure during insertion or removal is monitored and collected, thereby determining whether the product under test is placed correctly, whether the connector on the flexible circuit board is installed correctly, and whether the side plug is aligned with the flexible circuit board during testing. The quick-release assembly allows for rapid installation and removal of the side plug from the track connecting plate, improving the product's applicability and convenience. Therefore, this invention can monitor the real-time insertion and removal pressure at the flexible circuit board connector, ensuring that the side insertion mechanism of the monitoring device will not damage the product.

[0016] like Figures 1 to 6 As shown, this utility model includes two sets of symmetrically arranged slide rails 1 and a track connecting plate slidably connected to the slide rails 1. The front end of the track connecting plate is provided with a side plug mounting groove 2, and a quick-release assembly 3 is provided in the side plug mounting groove 2. The side plug 4 is detachably installed on the quick-release assembly 3. At the rear end of the track connecting plate, a sensor cover plate 6 is connected to the rear end of the track connecting plate through several sliding limit posts 5. A pressure sensor 7 is built into the sensor cover plate 6. A buffer spring 8 is also provided on the track connecting plate. The buffer spring 8 abuts against the pressure sensor 7. The pressure sensor 7 is electrically connected to an external detection device. This invention connects to an external driving component via the track connecting plate, driving the side plug 4, installed in the side plug mounting slot 2, to slide along the slide rail 1 towards the flexible circuit board under test and insert the side plug 4 into the flexible circuit board under test. The pressure sensor located in the sensor cover 6, in cooperation with the buffer spring 8, monitors and collects the real-time pressure during insertion or removal, thereby determining whether the product under test is placed correctly, whether the connector on the flexible circuit board is installed correctly, and whether the side plug 4 is aligned with the flexible circuit board under test during the test. The quick-release assembly 3 allows for quick installation and removal of the side plug 4 from the track connecting plate, improving the product's applicability and convenience.

[0017] In this utility model, the track connecting plate is composed of a first connecting plate 9 and a second connecting plate 10 that are slidably connected to two sets of slide rails 1 respectively. The side plug mounting groove 2 is opened at the front end of the first connecting plate 9. The sensor cover plate 6 is fixedly connected to the rear end of the second connecting plate 10. The front ends of a plurality of sliding limiting posts 5 are threaded to the first connecting plate 9 and the ends are slidably connected to the second connecting plate 10. The front end of the buffer spring 8 is threaded to the first connecting plate 9 and the end is fixedly connected to the sensor cover plate 6 at the position corresponding to the pressure sensor 7. This utility model adopts a split-type track connecting plate, which is composed of a first connecting plate 9 and a second connecting plate 10. The first connecting plate 9 and the second connecting plate 10 are slidably connected to the slide rail 1, and the two are slidably connected by two sets of sliding limit posts 5. When the side plug 4 is used to perform a side insertion test on the flexible circuit board to be tested, the side plug 4 loaded by the first connecting plate 9 first contacts the connector of the flexible circuit board to be tested. There is a certain play between the first connecting plate 9 and the second connecting plate 10. When the first connecting plate 9 starts to compress the buffer spring 8, it drives the second connecting plate 10 to move backward and transmits the pressure to the pressure sensor 7 to realize real-time monitoring of the side insertion pressure.

[0018] In this utility model, a sliding step hole 11 adapted to the sliding limiting post 5 is provided in the second connecting plate 10. The front section of the sliding step hole 11 is adapted to the sliding limiting post 5, and the rear section is larger than the front section. A limiting ring 12 is threaded to the end of the sliding limiting post 5. The size of the limiting ring 12 is adapted to the rear section size of the sliding step hole 11.

[0019] In this invention, the quick-release assembly 3 includes a mounting plate 31, an integrally formed plug-in section 32 disposed at the lower end of the mounting plate 31, and a pressing ball 33 disposed within the plug-in section 32. The pressing ball 33 is connected to the inner wall of the plug-in section 32 by a spring and extends outward to the outside of the plug-in section 32. A slot 21 adapted to the plug-in section 32 is also provided in the side plug mounting groove 2, and a mounting arc surface 22 adapted to the pressing ball 33 is provided in the slot 21. A quick-release hole 91 is also provided on the first connecting plate 9 at the position corresponding to the mounting arc surface 22. The side plug 4 is detachably connected to the mounting plate 31 by several screws. The plug section 32 is aligned with the slot 21 and inserted. The inner wall of the slot 21 compresses the pressing ball 33 until the pressing ball 33 enters the mounting arc surface 22 and is locked in place, thus achieving installation positioning. When the mounting plate 31 needs to be replaced, a long rod adapted to the quick-release hole 91 is inserted through the quick-release hole 91 and the pressing ball 33 is pushed away from the mounting arc surface 22. Then the plug section 32 is pulled out from the slot 21. This achieves the quick-release and quick-installation characteristics of the mounting plate 31, improving the applicability and convenience of the equipment.
