Description

Technical Field

[0001] The present invention relates to the field of flexible printed circuit board (FPC) manufacturing equipment, and particularly to a probe profiling test module for a flexible FPC connector and a testing machine thereof. Background Art

[0002] A flexible printed circuit board, also known as an "FPC flexible board", is a printed circuit board made of a flexible insulating substrate. The FPC can provide excellent electrical performance, meet the requirements of smaller and higher-density installation designs, and also helps to reduce the assembly process and enhance reliability. The flexible printed circuit board FPC flexible board can be freely bent, wound, and folded, can withstand millions of dynamic bends without damaging the wires, can be arranged arbitrarily according to the spatial layout requirements, and can move and stretch arbitrarily in three-dimensional space, so as to achieve the integration of component assembly and wire connection; moreover, it can greatly reduce the volume and weight of electronic products and meet the development needs of electronic products towards high density, miniaturization, and high reliability.

[0003] During the manufacturing process of flexible FPC, a testing process is involved. After connecting it to a testing circuit in an electrical connection manner, various electrical index performances of the flexible FPC are simulated by the testing circuit. In the specific testing process, generally, multiple probes need to be independently contacted with multiple metal nickel sheets on the side of the flexible FPC tape body respectively, and at the same time, multiple probes need to be inserted into the jacks of a connector at one end of the flexible FPC to connect the flexible FPC to the testing circuit; based on this testing process requirement, during the automated testing process of the flexible FPC, multiple metal nickel sheets and the connector of the flexible FPC need to be connected to the testing circuit simultaneously. Generally, needle-shaped probes are used as electrical contact media. The technical difficulty in the contact process is that it is difficult to control the height of the contact position. When not fully contacted, the circuit cannot be conducted, and when the contact is excessive, the probe will bend and deform; in addition, the jacks in the connector often include multiple rows and multiple pieces. During the process of inserting the probe, higher relative position accuracy requirements are required for the two, and the relative positioning problem between the connector and the probe needs to be solved.

[0020] The present invention belongs to a mechanism and an automated device for testing the electrical parameters of flexible FPCs, and realizes the simultaneous connection of multiple nickel sheets and connectors of flexible FPCs to a test circuit to automatically test various electrical parameters after their manufacture. Specifically, the test machine of the present invention takes a test mechanism and an FPC support platform arranged at intervals up and down as the core. The flexible FPC to be tested is placed on the FPC support platform, and the whole is placed on a rotation feeding mechanism. The rotation feeding mechanism includes a double-layer feeding platform (i.e., a first sliding seat and a second sliding seat) arranged at intervals up and down. The FPC support platforms are respectively placed on the double-layer feeding platform. After a flexible FPC is placed on one FPC support platform, the feeding platform moves it linearly backward and pushes it under the test mechanism for testing, while the other layer of the feeding platform moves forward to the front side of the machine for loading the flexible FPC. In an alternating rotation loading and testing mode, the loading and testing are carried out synchronously to improve the overall machine testing efficiency; the test mechanism is driven by a test driving mechanism to move up and down in the vertical direction so that its first probe contacts multiple nickel sheets of the flexible FPC loaded on the FPC support platform from top to bottom to complete the electrical conduction of the nickel sheets.The special feature is that a probe profiling test module is provided at one end of the test box of the test mechanism of the present invention. The probe profiling test module outputs power on the left and right sides, and is used to insert multiple probes into the connector of the flexible FPC from the outside to achieve electrical conduction of the connector; at the same time, the present invention sets a height difference between the plug-in drive block of the probe profiling test module and the bottom surface of the test box, so that the bottom surface of the plug-in drive block maintains the same height as the bottom surface of the first probe. In the process of connecting the nickel sheet, when the plug-in drive block is synchronized with the first probe to descend, the bottom surface of the plug-in drive block is used to resist the flexible FPC belt body to achieve the ultimate limit of the first probe, so as to avoid excessive descent and bending and deformation; further, The FPC support of the present invention is also provided with a connector clamping assembly, and the connector of the flexible FPC placed in the FPC slot of the FPC support is positioned by the connector clamping assembly to ensure the position accuracy when the second probe is subsequently plugged in, and can effectively avoid the occurrence of positional deviation when the second probe is inserted. Furthermore, the probe profiling test module of the present invention as a whole includes a load-bearing drive assembly, a socket assembly and a probe assembly. The load-bearing drive assembly outputs linear power to drive the socket assembly and the probe assembly to approach the connector from the outside so as to insert the second probe into the jack in the connector. The side wall of the socket assembly close to the connector has a corresponding The connector of the present invention is provided with a profiling seat. Before the second probe is plugged in, the profiling seat is firstly set on the outside of the connector to accurately position the connector before plugging in, so that multiple rows of multiple second probes can be accurately inserted into the jacks of the connector; as the sleeve assembly continues to move toward the connector, the fixed seat of the sleeve assembly drives the probe assembly to move through the connecting piece, so that the second probe of the probe assembly is inserted into the jack of the connector from the profiling seat, thereby completing the electrical conduction of the connector; in particular, one end of the connecting piece of the present invention is fixed on the floating seat of the probe assembly, and the other end of the connecting piece movably passes through the through hole of the fixed seat. When the fixed seat is subjected to the driving force moving toward the connector, the floating spring transmits The floating seat is driven by the floating spring to move toward the connector through the limit ring of the connector. This linkage driving method using the floating spring as the transmission medium enables the second probe to have elastic buffering ability in the plug-in hole of the connector, which can effectively avoid the bending, deformation and breakage of the second probe caused by rigid contact during the plug-in process. In addition, the floating spring is compressed during the process. When the second probe is inserted into the connector, the internal elastic force of the floating spring has a tendency to drive the second probe to be pressed toward the connector, thereby realizing real-time and continuous compression of the inserted second probe, effectively ensuring the plug-in stability and avoiding disconnection during the test.

[0057] As Figure 7 、 Figures 16 to 21As shown in the figure, the present invention provides a probe profiling test module for a flexible FPC connector, which is arranged in a flexible FPC testing machine and is used to connect the connector of the flexible FPC to a test circuit. It includes a bearing driving component, a socketing component and a probe component. Among them, the bearing driving component is arranged at one end of the bottom of the testing mechanism of the testing machine and moves up and down with the testing mechanism so as to approach the flexible FPC below; the bottom surface of the bearing driving component is the limit reference surface. When the first probe of the testing mechanism is electrically connected to the nickel sheet of the flexible FPC, the bottom surface of the bearing driving component is close to the flexible FPC, which is used to limit the descending height of the first probe to the limit, and the bearing driving mechanism moves to the outside of the connector at one end of the flexible FPC; the bearing driving component outputs linear power in the horizontal direction; the socketing component is connected to the output end of the bearing driving component and approaches or moves away from the connector from the outside under the drive of the bearing driving component so as to socket with the connector; the probe component is arranged outside the socketing component and is spaced from the socketing component; the probe component is flexibly connected to the socketing component through a connecting piece; a second probe is arranged on one side of the probe component, and the second probe horizontally penetrates through the socketing component; when the socketing component drives the probe component to approach the connector and the socketing component sockets with the connector, the second probe flexibly inserts into the connector to electrically conduct the connector.

[0058] The bearing driving component includes a test support 551, a test plugging cylinder 552 and a plugging driving block 5511. Among them, the test support 551 is arranged in the test box 52 of the testing mechanism; the test plugging cylinder 552 is arranged at the bottom of the test support 551 and is located on the bottom plate of the test box 52, and its output is set horizontally towards the outside of the test box 52; the plugging driving block 5511 is connected to the output end of the test plugging cylinder 552 and horizontally extends below the bottom plate of the test box 52, and the bottom surface of the plugging driving block 5511 is the limit reference surface.

[0059] The height of the limit reference surface is the same as the bottom height of the first probe 54 arranged on the bottom plate of the test box 52, so that during the descending process, the limit reference surface and the first probe 54 respectively contact the FPC strip 01 of the flexible FPC0 and the nickel sheet on the side of the FPC strip 01 at the same time.

[0060] The socketing component includes a fixed seat 553 and a profiling sleeve 554. Among them, the fixed seat 553 is vertically connected to the outer side wall of the plugging driving block 5511; the profiling sleeve 554 is arranged on the side wall of the fixed seat 553 close to the connector 02, and a socketing groove body is opened in the middle of the profiling sleeve 554 for socketing and covering the connector 02.

[0061] The probe assembly includes a floating base 555, an adapter board 556, and a second probe 557. Among them, the floating base 555 is horizontally spaced on the other side of the fixed base 553 and is flexibly connected to the fixed base 553 through at least two connecting members 558; the adapter board 556 is disposed on a side wall of the floating base 555 away from the connector 02 and is in communication with an external test circuit; at least two second probes 557 are included, and one ends of the at least two second probes 557 are connected to the adapter board 556, and the other ends horizontally pass through the floating base 555 and the fixed base 553 and extend into the profiling sleeve 554, so as to be inserted into the connector 02 during testing to connect the connector 02 to the test circuit.

[0062] One end of the connecting member 558 is fixedly connected to the side wall of the floating base 555, and the other end horizontally passes through a through hole C opened on the fixed base 553; the outer diameter of the connecting member 558 is not greater than the inner diameter of the through hole C, so as to move freely in the through hole C; a protruding limiting ring 559 is further provided on the connecting member 558; a floating spring 5510 is provided between the limiting ring 559 and the side wall of the fixed base 553; the floating spring 5510 is sleeved on the connecting member 558, and the elastic force of the floating spring 5510 has a tendency to push the fixed base 553 towards the floating base 555 in the natural state; when the fixed base 553 moves towards the connector 02 to sleeve the connector 02, the driving force is transmitted to the limiting ring 559 and the connecting member 558 through the floating spring 5510, so as to drive the floating base 555 and the second probe 557 towards the connector 02, and make the second probe 557 flexibly inserted into the connector 02.

[0063] In this embodiment, by controlling the position height of the plugging drive block 5511 and the first probe 54 of the testing mechanism 5, when the probe profiling test module 55 descends along with the testing mechanism 5, the bottom surface of the plugging drive block 5511 is used as the limit reference surface, which can effectively avoid the bending deformation or breakage of the first probe 54 during the process of contacting the nickel sheet of the flexible FPC0 due to excessive descent. At the same time, for the process of connecting the connector 02 to the test circuit, a cooperative method of the socketing component and the probe component is adopted. While the profiling sleeve 554 of the socketing component is used to preset and position the connector 02 in advance, the socketing component drives the probe component to approach the connector 02 synchronously, so that the second probe 557 of the probe component is inserted into the connector 02 to connect the connector 02 to the test circuit. The socketing and positioning of the socketing component for the connector 02 can effectively ensure the relative position between the connector 02 and the second probe 557, enabling multiple second probes 557 to be accurately positioned respectively with multiple jacks in the connector 02 before plugging. At the same time, the socketing component and the probe component are flexibly connected through the connecting piece 58, so that the second probe 557 is flexibly plugged during the process of inserting into the connector 02, effectively avoiding the bending deformation problem of the second probe 557 due to uneven or excessive force during the plugging process. At the same time, based on the structure of the connecting piece 58, during the transmission of force, the plugging driving force received by the movable seat 553 is first transmitted to the floating spring 5510, and after being transmitted to the limiting ring 559 on the connecting piece 558 through the floating spring 5510, the connecting piece 558 drives the floating seat 555 and the second probe 557 thereon to move towards the connector 02 so that the second probe 557 is inserted into the connector 02, and at this time the floating spring 5510 is compressed. Based on the above force transmission path during the plugging process of the second probe 557 and the connector 02, after the second probe 557 is inserted into the connector 02, since the floating spring 5510 is compressed, its elastic force will continuously be transmitted to both sides. The elastic force transmitted to the second probe 557 through the limiting ring 559 will drive the second probe 557 to maintain the state of continuously inserting into the connector 02, ensuring the relative position stability between the second probe 557 and the connector 02 during the plugging process and avoiding disconnection during the test.

Embodiment 4

[0072] As Figure 23 shown, as an embodiment of the present invention, the testing machine of this embodiment uses a feeding platform 8 as the driving mechanism of the FPC support 3. The feeding platform 8 is a single-layer structure. Compared with Embodiment 2, this single-layer feeding method cannot perform feeding and discharging simultaneously while performing feeding and testing, and the overall testing efficiency is lower than that of the rotation feeding platform 6 in Embodiment 2.

[0073] Furthermore, the present invention designs a testing mechanism that realizes the electrical connection between the probe and the nickel sheet and the connector by lifting the whole testing mechanism and horizontally pushing and inserting the end of the probe profiling test module at the same time. The height difference of the testing mechanism is used to limit the first probe to its limit position to avoid bending and deformation. The connector is accurately positioned by pressing and positioning the connector and cooperating with the profiling socket, and the probe assembly is flexibly inserted into the connector by the power during socketing, realizing buffering during the insertion process, reducing the bending and deformation of the second probe, and realizing real-time continuous pressing during the insertion process, effectively maintaining the electrical connection stability of the flexible FPC connector's probe profiling test module and its testing machine. The present invention belongs to the mechanism and automation equipment for testing the electrical parameters of flexible FPCs, and realizes the simultaneous access of multiple nickel sheets and connectors of the flexible FPC to the test circuit to complete various electrical parameter automatic tests after its manufacture. Specifically, the testing machine of the present invention takes the testing mechanism and the FPC support platform arranged at intervals up and down as the core. The flexible FPC to be tested is placed on the FPC support platform, and the whole is placed on the rotation feeding mechanism. The rotation feeding mechanism includes a double-layer feeding platform (i.e., the first sliding seat and the second sliding seat) arranged at intervals up and down. The FPC support platforms are respectively placed on the double-layer feeding platform. When a flexible FPC is placed on an FPC support platform, the feeding platform moves it linearly backward and pushes it under the testing mechanism for testing, and the other layer of the feeding platform moves forward to the front side of the machine for loading the flexible FPC, so as to realize the synchronous loading and testing in an alternating rotation mode, improving the testing efficiency of the whole machine; the testing mechanism is driven by the testing driving mechanism to move up and down in the vertical direction, so that its first probe contacts the multiple nickel sheets of the flexible FPC loaded on the FPC support platform from top to bottom to complete the electrical conduction of the nickel sheets.The special feature is that a probe profiling test module is provided at one end of the test box of the test mechanism of the present invention. The probe profiling test module outputs power on the left and right sides, and is used to insert multiple probes into the connector of the flexible FPC from the outside to achieve electrical conduction of the connector; at the same time, the present invention sets a height difference between the plug-in drive block of the probe profiling test module and the bottom surface of the test box, so that the bottom surface of the plug-in drive block maintains the same height as the bottom surface of the first probe. In the process of connecting the nickel sheet, when the plug-in drive block is synchronized with the first probe to descend, the bottom surface of the plug-in drive block is used to resist the flexible FPC belt body to achieve the ultimate limit of the first probe, so as to avoid excessive descent and bending and deformation; further, The FPC support of the present invention is also provided with a connector clamping assembly, and the connector of the flexible FPC placed in the FPC slot of the FPC support is positioned by the connector clamping assembly to ensure the position accuracy when the second probe is subsequently plugged in, and can effectively avoid the occurrence of positional deviation when the second probe is inserted. Furthermore, the probe profiling test module of the present invention as a whole includes a load-bearing drive assembly, a socket assembly and a probe assembly. The load-bearing drive assembly outputs linear power to drive the socket assembly and the probe assembly to approach the connector from the outside so as to insert the second probe into the jack in the connector. The side wall of the socket assembly close to the connector has a corresponding The connector of the present invention is provided with a profiling seat. Before the second probe is plugged in, the profiling seat is firstly set on the outside of the connector to accurately position the connector before plugging in, so that multiple rows of multiple second probes can be accurately inserted into the jacks of the connector; as the sleeve assembly continues to move toward the connector, the fixed seat of the sleeve assembly drives the probe assembly to move through the connecting piece, so that the second probe of the probe assembly is inserted into the jack of the connector from the profiling seat, thereby completing the electrical conduction of the connector; in particular, one end of the connecting piece of the present invention is fixed on the floating seat of the probe assembly, and the other end of the connecting piece movably passes through the through hole of the fixed seat. When the fixed seat is subjected to the driving force moving toward the connector, the floating spring transmits The floating seat is driven by the floating spring to move toward the connector through the limit ring of the connector. This linkage driving method using the floating spring as the transmission medium enables the second probe to have elastic buffering ability in the plug-in hole of the connector, which can effectively avoid the bending, deformation and breakage of the second probe caused by rigid contact during the plug-in process. In addition, the floating spring is compressed during the process. When the second probe is inserted into the connector, the internal elastic force of the floating spring has a tendency to drive the second probe to be pressed toward the connector, thereby realizing real-time and continuous compression of the inserted second probe, effectively ensuring the plug-in stability and avoiding disconnection during the test.
