Description

Technical Field

[0001] This utility model relates to the field of FFC line detection technology, specifically to an intelligent detection device for FFC line terminals. Background Technology

[0002] In the electronics manufacturing industry, flexible flat cables (FFCs) are widely used in consumer electronics, automotive electronics, and medical devices due to their small size and flexible wiring. The connection reliability of FFC terminals directly affects the overall performance of the device; therefore, strict testing of electrical parameters such as conductivity and impedance is required during the production process. Traditional processes require first fixing the FFC with mechanical clamps and then manually connecting testing instruments. This step-by-step operation leads to low testing efficiency and uneven contact pressure between the test probes and terminals, resulting in low test reliability. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent FFC wire terminal detection device that integrates clamping and detection functions, thereby improving the detection efficiency and reliability of FFC wire terminals.

[0004] An intelligent detection device for FFC wire terminals includes a driving component and a detection fixture. The detection fixture includes an upper clamping plate, a rotating clamping plate, a PCB assembly, and a positioning assembly. The driving component is connected to one end of the upper clamping plate, and the upper clamping plate is connected to the rotating clamping plate. The PCB assembly is clamped between the upper clamping plate and the rotating clamping plate. The rotating clamping plate is rotatably connected to the positioning assembly, which is used to clamp one end of the FFC wire terminal. The PCB assembly is provided with a test probe assembly, which can pass through the rotating clamping plate and the positioning assembly to abut against the terminal of the FFC wire.

[0005] In the above scheme, since the rotating clamp is rotatably connected to the positioning component and is also connected to the upper clamp, when the driving component pushes one end of the upper clamp, the rotating clamp can rotate along the positioning component, thereby moving the test probe assembly away from the positioning component. After the positioning component positions one end of the FFC line terminal, the driving component drives the upper clamp to reset, and the test probe assembly can pass through the rotating clamp and the positioning component to abut against the FFC line terminal. The positioning component can ensure the reliability of the test probe assembly test. By integrating the PCB assembly with the mechanical positioning structure, the electrical performance test and physical positioning of the FFC line terminal are completed simultaneously, which significantly improves the test efficiency and avoids the time loss of traditional step-by-step operation.

[0006] Furthermore, the positioning component includes a positioning base and a positioning block. The positioning base is provided with a positioning groove, the positioning block is installed on the positioning groove, and the positioning block is provided with a recess. A placement slot is formed between the recess and the positioning groove.

[0007] In the above scheme, the groove on the positioning block and the positioning slot on the positioning base combine to form a placement slot. The placement slot enables the FFC line to be placed and positioned quickly, which is beneficial for the test probe assembly to accurately connect to the terminals of the FFC line for testing.

[0008] Furthermore, the positioning block is provided with a connecting through hole, through which the test probe assembly can pass.

[0009] In the above scheme, the groove is set at the lower end of the positioning block, and the connecting through hole is set at the upper end of the positioning block. The connecting through hole allows the placement slot to communicate with the outside, so that the test probe assembly can pass through the connecting through hole and abut against the FFC wire embedded in the placement slot, thereby realizing the testing of the FFC terminal.

[0010] Furthermore, the positioning base is provided with a connecting block, the rotating clamp is provided with a rotating block, the rotating block is clamped between the two connecting blocks, and the connecting block and the rotating block are rotatably connected by a connecting shaft.

[0011] In the above scheme, the connecting shaft passes through the connecting block and the rotating block between the two connecting blocks to realize the rotational connection between the rotating block and the connecting block, thereby realizing the rotational connection between the rotating clamp and the positioning base. The structure is simple and compact, and easy to assemble and disassemble.

[0012] Furthermore, the rotating clamp is provided with a protruding structure, through which the test probe assemblies all pass.

[0013] In the above scheme, the protruding structure isolates the test probe assembly from the outside world, preventing external influences on the test probe assembly and ensuring the stability of the test. At the same time, when the protruding structure abuts against the positioning block, the fixture does not rotate, which can prevent the test probe assembly from overshooting and damaging the terminals of the FFC line.

[0014] Furthermore, the PCB assembly includes a PCB board and a connecting terminal block, the PCB board being mounted on the upper clamping plate, and the connecting terminal block being mounted on the PCB board.

[0015] In the above scheme, the PCB board serves as the core circuit carrier, integrating test circuits, signal processing modules, and communication interfaces. It is responsible for sending detection signals to the test probe assembly and collecting the electrical responses of the FFC terminals, such as conduction resistance and insulation resistance. The terminal block serves as a bridge between the PCB and external devices, and the test data is uploaded to the host computer or PLC through cables or connectors to achieve automated judgment.

[0016] Furthermore, the positioning base has a clearance groove at one end relative to the connecting terminal block.

[0017] In the above scheme, since the end of the upper clamp plate that is installed with the connecting terminal block will be driven downward by the driving force of the driving component, setting a clearance groove on the positioning base can avoid interference between the connecting terminal block and the positioning base, thereby ensuring the normal operation of the testing fixture.

[0018] Furthermore, the drive assembly includes a drive component and a connecting plate, the output end of the drive component is connected to the connecting plate, and the connecting plate is connected to the upper clamping plate.

[0019] In the above scheme, the driving component can be a cylinder. When it is necessary to place the FFC wire, the output end of the driving component drives the connecting plate to descend, thereby causing one end of the upper clamp plate connected to the connecting plate to descend. In this way, the end of the PCB assembly that is installed with the test probe assembly will be raised, so that the FFC wire can be placed in the placement slot.

[0020] This utility model discloses an intelligent testing device for FFC wire terminals, which integrates clamping and testing functions, improving the efficiency and reliability of FFC wire terminal testing. Because the rotating clamp is rotatably connected to the positioning component, and the rotating clamp is also connected to the upper clamp, when the driving component pushes one end of the upper clamp, the rotating clamp rotates along the positioning component, causing the test probe assembly to move away from the positioning component. After the positioning component positions one end of the FFC wire terminal, the driving component drives the upper clamp to reset, allowing the test probe assembly to pass through the rotating clamp and the positioning component and abut against the FFC wire terminal. The positioning component ensures the reliability of the test probe assembly test. By integrating the PCB assembly with the mechanical positioning structure, the electrical performance testing and physical positioning of the FFC wire terminals are completed simultaneously, significantly improving testing efficiency and avoiding the time loss of traditional step-by-step operations.

[0026] The following will describe in further detail an intelligent detection device for FFC wire terminals according to specific embodiments and accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown in a preferred embodiment, the intelligent detection device for FFC wire terminals of this utility model includes a driving component 1 and a detection fixture 2. The detection fixture 2 includes an upper clamping plate 21, a rotating clamping plate 22, a PCB assembly 23, and a positioning component 24. The driving component 1 is connected to one end of the upper clamping plate 21, the upper clamping plate 21 is connected to the rotating clamping plate 22, the PCB assembly 23 is clamped between the upper clamping plate 21 and the rotating clamping plate 22, the rotating clamping plate 22 is rotatably connected to the positioning component 24, the positioning component 24 is used to clamp one end of the FFC wire terminal, and the PCB assembly 23 is provided with a test pin assembly 25, which can pass through the rotating clamping plate 22 and the positioning component 24 to abut against the terminal of the FFC wire. Since the rotating clamp 22 is rotatably connected to the positioning component 24, and the rotating clamp 22 is also connected to the upper clamp 21, when the driving component 1 pushes one end of the upper clamp 21, the rotating clamp 22 can rotate along the positioning component 24, thereby moving the test probe assembly 25 away from the positioning component 24. After the positioning component 24 positions one end of the FFC line terminal, the driving component 1 drives the upper clamp 21 to reset, and the test probe assembly 25 can pass through the rotating clamp 22 and the positioning component 24 to abut against the terminal of the FFC line. The positioning component 24 can ensure the reliability of the test probe assembly 25. By integrating the PCB assembly 23 with the mechanical positioning structure, the electrical performance testing and physical positioning of the FFC line terminal are completed simultaneously, which significantly improves the testing efficiency and avoids the time loss of traditional step-by-step operations.

[0028] like Figure 2As shown, in some embodiments, the positioning component 24 includes a positioning base 241 and a positioning block 242. The positioning base 241 is provided with a positioning groove 3, and the positioning block 242 is mounted on the positioning groove 3. The positioning block 242 is provided with a groove 4, and a placement slot is formed between the groove 4 and the positioning groove 3. The groove 4 on the positioning block 242 and the positioning groove 3 on the positioning base 241 combine to form a placement slot. The placement slot enables the rapid placement and positioning of the FFC wire, which is beneficial for the test probe component 25 to accurately connect to the terminals of the FFC wire for testing.

[0029] like Figure 2 As shown, in some embodiments, the positioning block 242 is provided with a connecting through hole 5, through which the test probe assembly 25 can pass. The groove 4 is provided at the lower end of the positioning block 242, and the connecting through hole 5 is provided at the upper end of the positioning block 242. The connecting through hole 5 enables the placement slot to communicate with the outside, so that the test probe assembly 25 can pass through the connecting through hole 5 and abut against the FFC wire embedded in the placement slot, thereby realizing the testing of the FFC terminal.

[0030] like Figure 2 and Figure 3 As shown, in some embodiments, the positioning base 241 is provided with a connecting block 2411, and the rotating clamping plate 22 is provided with a rotating block 221. The rotating block 221 is clamped between the two connecting blocks 2411, and the connecting blocks 2411 and the rotating block 221 are rotatably connected by a connecting shaft 6. The connecting shaft 6 passes through the connecting block 2411 and the rotating block 221 between the two connecting blocks 2411, realizing the rotatable connection between the rotating block 221 and the connecting block 2411, thereby realizing the rotatable connection between the rotating clamping plate 22 and the positioning base 241. The structure is simple and compact, and easy to assemble and disassemble.

[0031] like Figures 1 to 3 As shown, in some embodiments, the rotating clamp is provided with a protrusion structure 222, through which the test probe assembly 25 passes. The protrusion structure 222 isolates the test probe assembly 25 from the outside world, preventing external influence on the test probe assembly 25 and ensuring the stability of the test. At the same time, when the protrusion structure 222 abuts against the positioning block 242, the clamp does not rotate, which can prevent the test probe assembly 25 from overshooting and damaging the terminals of the FFC line.

[0032] like Figure 1 and Figure 4As shown, in some embodiments, the PCB assembly 23 includes a PCB board 231 and a connecting terminal block 232. The PCB board 231 is mounted on the upper clamping plate 21, and the connecting terminal block 232 is mounted on the PCB board 231. The PCB board 231 serves as the core circuit carrier, integrating test circuits, signal processing modules, and communication interfaces. It is responsible for sending detection signals to the test probe assembly 25 and collecting the electrical responses of the FFC terminals, such as conduction resistance and insulation resistance. The connecting terminal block 232 acts as a bridge between the PCB and external devices, uploading the detection data to a host computer or PLC via cables or connectors to achieve automated judgment.

[0033] like Figure 4 As shown, in some embodiments, the positioning base 241 has a clearance groove 7 at one end relative to the connecting terminal block 232. Since the end of the upper clamping plate 21 where the connecting terminal block 232 is mounted will be driven downward by the driving force of the driving member 11, the clearance groove 7 on the positioning base 241 can prevent interference between the connecting terminal block 232 and the positioning base 241, thereby ensuring the normal operation of the detection fixture 2.

[0034] like Figure 1 As shown, in some embodiments, the driving assembly 1 includes a driving element 11 and a connecting plate 12. The output end of the driving element 11 is connected to the connecting plate 12, and the connecting plate 12 is connected to the upper clamping plate 21. The driving element 11 can be a cylinder. When it is necessary to place the FFC wire, the output end of the driving element 11 drives the connecting plate 12 to descend, thereby causing one end of the upper clamping plate 21 connected to the connecting plate 12 to descend. This raises one end of the PCB assembly 23 where the test probe assembly 25 is mounted, allowing the FFC wire to be placed in the placement slot.

[0035] The working principle and process of the intelligent detection device for FFC wire terminals of this utility model are as follows: the driving component 1 drives one end of the upper clamping plate 21 to descend, so that one end of the PCB component 23 that mounts the test pin component 25 is raised, placing one end of the FFC wire terminal in the placement slot. Then, the driving component 1 resets and drives one end of the upper clamping plate 21 to rise, and the end of the PCB component 23 that mounts the test pin component 25 descends until it passes through the connecting through hole 5 and abuts against the terminal on the FFC wire. The connecting terminal block 232 is connected to the external detection equipment, thereby realizing the detection of the FFC wire terminal.
