Description

Technical Field

[0001] This utility model relates to the field of circuit testing technology, and in particular to a device for rapidly testing FPC circuits. Background Technology

[0002] During circuit manufacturing, FPCs typically require continuity testing to ensure proper functioning. In the initial trial production and sampling stages, due to the high cost of manufacturing testing equipment, manual wire bonding is currently the most common method for testing. This process requires manually soldering wires one by one to the test points, which is not only time-consuming but also prone to errors, especially in the testing of high-density circuit boards. Furthermore, manual operation requires not only a high level of technical skill but also a considerable amount of time to complete the test, which greatly limits production efficiency. Not only is the testing efficiency low, but improper operation can also cause the test point pads to detach, increasing the uncertainty and complexity of the test. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a device for rapidly testing FPC circuits, thus solving the technical problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rapid testing device for FPC circuits, including a pair of side plates, a base plate fixedly installed between the pair of side plates, multiple test probes installed inside the base plate, and a test tray for placing FPCs movably installed on the top of the base plate. A cover plate is installed on the top of the test tray, and a through hole for the test probes to pass through is opened inside the test tray. Elastic columns are fixedly installed on both sides inside the base plate, and a slot for inserting the elastic columns is opened at the bottom of the test tray. A support rod is fixedly installed on one side of the side plate, and a buckle plate is rotatably connected to the upper end of the support rod. The buckle plate is set above the cover plate and fits against the cover plate.

[0005] Furthermore, positioning posts are fixedly installed at the four corners of the bottom of the test tray, and guide cylinders for the positioning posts to slide up and down are provided at the four corners of the base plate.

[0006] Furthermore, a pair of L-shaped limiting corner blocks are fixedly installed on both sides of the test tray.

[0007] Furthermore, a fastening mechanism is provided between the pair of side plates to drive the two fastening plates to rotate in opposite directions. The fastening mechanism includes a bracket fixedly connected to the side of the side plate. A rotating shaft is rotatably connected to both sides of the bracket. The two rotating shafts are respectively fixedly connected to the two fastening plates, and a transmission component is provided between the two rotating shafts.

[0008] Furthermore, the transmission component includes a first synchronous pulley fixedly sleeved on the outside of one of the rotating shafts and a second synchronous pulley rotatably mounted on the bottom of the bracket. The first and second synchronous pulleys are both mounted on the outside of a synchronous belt, and the shaft of the second synchronous pulley is fixedly connected to a driving gear. The other rotating shaft is fixedly sleeved on the outside of a driven gear that meshes with the driving gear.

[0009] Furthermore, a knob is fixedly connected to the upper end of one of the rotating shafts through the bracket.

[0010] By employing the above technical solution, this utility model provides a device for rapidly testing FPC circuits, which has at least the following beneficial effects:

[0011] 1. This utility model, by setting test probes and test trays, along with cover plates and buckles, can fix the FPC on the test tray. Multiple test probes can be used to test the test points of the FPC circuit.

[0012] 2. By setting up a clamping mechanism, this utility model allows for easy installation of the FPC. When installing the FPC, only one hand needs to press down on the cover plate, and the other hand can turn the knob to rotate the two clamping plates onto the cover plate, thereby fixing the FPC. This simplifies the testing process and makes the FPC easier to use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] During the circuit manufacturing process, it is usually necessary to perform continuity tests on FPCs to ensure that they function properly. Currently, manual wire bonding is commonly used for testing. This process requires manually soldering wires one by one to the test points, which is not only time-consuming and inefficient, but also prone to causing the test point pads to fall off due to improper operation, increasing the uncertainty and complexity of the test.

[0022] Example 1

[0023] To address the shortcomings of the above testing methods, please refer to [link / reference needed]. Figures 1-3This utility model provides a rapid testing device for FPC circuits, capable of quickly completing continuity tests on FPC circuits within a short time. The device uses a pair of side plates 1 as a base, with a base plate 2 fixedly installed between the side plates 1. Multiple test probes 3 are installed inside the base plate 2, and a test tray 4 for placing the FPC is movably installed on the top of the base plate 2. The distribution of the multiple test probes 3 corresponds to the test points on the FPC. A cover plate 10 is installed on the top of the test tray 4, and a through hole 401 for the test probes 3 to pass through is opened inside the test tray 4. Elastic posts 5 are fixedly installed on both sides of the inside of the base plate 2, and slots for inserting the elastic posts 5 are opened at the bottom of the test tray 4. A support rod 6 is fixedly installed on one side of the side plate 1, and a buckle plate 7 is rotatably connected to the upper end of the support rod 6. The buckle plate 7 is positioned above the cover plate 10 and fits against the cover plate 10. During testing, the FPC is placed... Place the FPC on the test tray 4, then cover the test tray 4 with the cover plate 10. Press down on the cover plate 10 to lower the FPC and the test tray 4. At this time, the elastic column 5 deforms until the test probe 3 passes through the through hole 401 and contacts the FPC. Then rotate the two buckles 7 to fasten them on the cover plate 10, which can limit the cover plate 10, the test tray 4 and the FPC. The test probe 3 can be used to test the test points of the FPC circuit, saving time and effort. After the test is completed, rotate the buckles 7 to remove them from the cover plate 10. The test tray 4 can be lifted by the elastic force of the elastic column 5, making it easy to remove the FPC. This device can quickly complete the continuity test of the FPC circuit in a short time and avoids the risk of test points falling off due to manual soldering.

[0024] To ensure that the test points on the FPC circuit are aligned with the test probes 3, positioning posts 402 are fixedly installed at the four corners of the bottom of the test tray 4. Guide cylinders 201 are provided at the four corners of the base plate 2 to allow the positioning posts 402 to slide up and down. When the test tray 4 moves the FPC down, the positioning posts 402 can move along the guide cylinders 201 to guide the descent of the test tray 4, so as to avoid the position of the test tray 4 from deviating from the test probes 3 and ensure the accuracy of the test.

[0025] When the cover plate 10 is placed on the test tray 4, it is also necessary to ensure that the cover plate 10 is aligned with the test tray 4. Therefore, a pair of L-shaped limiting corner blocks 8 are fixedly installed on both sides of the test tray 4. The limiting corner blocks 8 are used to limit the cover plate 10. The cover plate 10 can fall between the four limiting corner blocks 8 and completely overlap with the test tray 4 to ensure the fixing effect of the FPC.

[0026] Example 2

[0027] After placing the cover plate 10 on the test tray 4, one hand needs to hold the cover plate 10 down while the other hand rotates the two latch plates 7 onto the cover plate 10 to limit its position. To simplify this step, refer to... Figure 4 and Figure 5 As shown, a fastening mechanism 9 is provided between a pair of side plates 1 to drive the two buckle plates 7 to rotate in opposite directions. The fastening mechanism 9 includes a bracket 91 fixedly connected to the side of the side plate 1. A rotating shaft 92 is rotatably connected to both sides of the bracket 91. The two rotating shafts 92 are respectively fixedly connected to the two buckle plates 7, and a transmission component 93 is provided between the two rotating shafts 92. When one rotating shaft 92 rotates, it can drive the other transmission component 93 to reverse, thereby realizing the reverse rotation of the two buckle plates 7. The transmission component 93 includes a first synchronous pulley 931 fixedly sleeved on the outside of one of the rotating shafts 92 and a second synchronous pulley 932 rotatably mounted on the bottom of the bracket 91. A synchronous belt 933 is installed on the outside of both the first synchronous pulley 931 and the second synchronous pulley 932, and a drive gear 934 is fixedly connected to the axis of the second synchronous pulley 932. Another rotating shaft 92 has a driven gear 935 that meshes with the driving gear 934 fixedly sleeved on its outside. The upper end of one of the rotating shafts 92 passes through the bracket 91 and is fixedly connected to a knob 936. Rotating the knob 936 drives one of the rotating shafts 92 to rotate, which drives the first synchronous pulley 931 to rotate. The first synchronous pulley 931 drives the second synchronous pulley 932 to rotate through the synchronous belt 933. The second synchronous pulley 932 drives the driving gear 934 to rotate, and the driving gear 934 drives the driven gear 935 to rotate in reverse. The other rotating shaft 92 can also rotate in reverse with the driven gear 935, thereby driving the two buckle plates 7 to rotate in the opposite direction. In this way, only one hand needs to press the cover plate 10, and the other hand needs to turn the knob 936 to drive the two buckle plates 7 to rotate onto the cover plate 10, which can further simplify the operation steps of the device and make it easier to use.
