Description

Technical Field

[0001] This utility model relates to the field of automated production and testing technology of PCBA (Printed Circuit Board Assembly), specifically to a PCB module testing device and an integrated production system. Background Technology

[0002] In the current PCBA production process, the core board, as a key functional component, directly determines the quality of the final product through its assembly precision, program burning accuracy, and functional integrity.

[0003] Existing FCT tests mostly employ static testing methods, which cannot simulate the dynamic working scenarios of the core board in actual applications. This results in some potential functional failures not being identified early, making the equipment prone to sudden damage during subsequent operation, and the test scenario fit is poor. Moreover, traditional devices have complex structures and large sizes, making it difficult to adapt to the production needs of different PCBA specifications, resulting in poor equipment versatility and insufficient equipment compatibility.

[0004] In the core board assembly stage, traditional production methods mostly rely on manual labor or a single mechanical structure to connect and fix the core board to the PCB board. This is prone to misalignment due to operational errors, resulting in distorted subsequent programming and testing data, or even damage to the core board or PCB board, leading to low core board assembly accuracy. At the same time, core board assembly, programming, and FCT testing need to be completed step by step at different workstations. Secondary damage is easily caused during workpiece transfer, and the connection between each process is time-consuming, making it difficult to adapt to the high-efficiency production requirements of automated production lines, resulting in fragmented processes and low efficiency.

[0030] Example 1

[0031] To achieve the above-mentioned goals, one embodiment of this utility model provides a PCB module testing device. For example, please refer to... Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the block structure of a PCB module testing device provided in one embodiment of the present invention. Figure 2 This is a simplified schematic diagram of a PCB module testing device provided in one embodiment of the present invention applied to an integrated PCB module production system. Figure 3 This is a simplified schematic diagram of the external structure of the PCB module testing device provided in one embodiment of the present invention, applied to an integrated PCB module production system. More specifically, Figure 2 and Figure 3 This only shows a portion of the structure of the integrated PCB module production system at the programming and testing station. See also... Figure 1 , Figure 2 and Figure 3 This utility model provides a PCB module testing device 40, including a test probe group 401, an analog load unit 402, and a signal acquisition unit 403 electrically connected; the test probe group 401 is configured to connect with the PCB board 70 (see...) Figure 5 Electrical connections are made between them; the analog load unit 402 is configured to be the core board 80 under test on the PCB board 70 (see Figure 5 The system provides a simulated load scenario; the signal acquisition unit 403 is configured to acquire the electrical parameters of the core board 80 under test.

[0032] The PCB module testing device 40 provided by this utility model enables electrical connection between the simulated load unit 402 and the PCB board 70 through the test probe group 401. The simulated load unit 402 provides a simulated load scenario for the core board 80 under test on the PCB board 70. The signal acquisition unit 403 can collect parameters of the core board 80 under test in real time to determine whether the core board 80 under test is functioning normally. Thus, the PCB module testing device 40 provided by this utility model can provide a dynamic test scenario for the core board 80 under test, simulating the dynamic working scenario of the core board in actual application, thereby realizing dynamic FCT testing of the core board 80 under test, identifying potential faults, improving early quality control, and effectively avoiding subsequent equipment damage.

[0033] Relevant statistics show that, in a specific embodiment of the PCB module testing device 40 provided by this utility model, the early quality control coverage rate is increased to over 95%, effectively avoiding subsequent equipment damage.

[0034] It should be noted that those skilled in the art should understand that the PCB module testing device 40 provided by this utility model does not limit the functions to be tested on the core board 80 under test. For example, the functions to be tested include, but are not limited to, communication functions, control functions, and power supply functions. Furthermore, this utility model does not limit the operating parameters of the core board 80 under test acquired by the signal acquisition unit 403. For example, the parameters include, but are not limited to, voltage, current, and other signal waveforms.

[0035] For example, please continue to see Figure 2 ,like Figure 2 As shown, in some exemplary embodiments, the test probe group 401 includes a custom probe board 4011, a probe 4012, and a probe holder 4013; the probe 4012 is disposed between the custom probe board 4011 and the probe holder 4013; the custom probe board 4011 is configured to realize the electrical connection between the PCB board 70 and the probe 4012, and the probe holder 4013 is configured to support the PCB board 70. Therefore, this invention, by placing the probe 4012 between the custom probe board 4011 and the probe holder 4013, not only makes the structure of the PCB module testing device 40 more compact, but also facilitates the connection of the end of the probe 4012 near the probe holder 4013 with the test point on the PCB board 70 placed on the probe holder 4013 during testing, thereby enabling testing of the core board 80 to be tested mounted on the PCB board 70.

[0036] Preferably, in some exemplary embodiments, a detection sensor for detecting the presence of the PCB board 70 on the probe holder 4013 is also provided around the probe holder 4013. Figure 2 (Not shown in the image). Therefore, by using a detection sensor, erroneous operation can be avoided, thereby effectively reducing testing errors. For example, the testing process will only be initiated when the detection sensor detects that the PCB board 70 is mounted on the probe holder 4013.

[0037] Exemplary, in some exemplary embodiments, the custom probe plate 4011 integrates electrical wiring connected to the probe 4012. Figure 2 (Not shown in the image). Therefore, by integrating the electrical wiring connected to the probe 4012 into the custom probe board 4011, the wiring layout between the probe board 4011 and the probe 4012 can be simplified, thereby making the use of the PCB module testing device 40 easier.

[0038] Exemplary embodiments, in some of these exemplary implementations, involve the probe 4012 engaging with test points on the PCB board 70. Thus, by engaging the probe 4012 with the test points on the PCB board 70, the core board 80 to be tested, mounted on the PCB board 70, can be tested.

[0039] Preferably, please continue to see Figure 2 ,like Figure 2 As shown, in some exemplary embodiments, the PCB module testing device 40 further includes a retractable guide structure 404. One end of the guide structure 404 is connected to the custom probe plate 4011, and the other end is connected to the probe holder 4013, so that the custom probe plate 4011 and the probe 4012 can move along their axial direction to approach or move away from the probe holder 4013, thereby realizing the docking or separation of the probe 4012 with the test point in the PCB board 70. It should be noted that the present invention does not limit the specific implementation of the guide structure 404. For example, the guide structure 404 can be, but is not limited to, a telescopic rod and a guide shaft.

[0040] Furthermore, the PCB module testing device 40 also includes at least one buffer disposed around the probe holder 4013. Figure 2 (Not shown in the image). Therefore, the buffer effectively protects the probe 4012 when it docks with the test point on the PCB board 70, preventing damage to the probe 4012 and achieving flexible docking between the probe 4012 and the test point on the PCB board 70. It should be noted that this invention does not limit the type of buffer. For example, the buffer can be, but is not limited to, a hydraulic buffer, an elastic buffer, etc. Anything understood by those skilled in the art that can achieve the corresponding function of this invention is within the scope of protection of this invention.

[0041] For example, please continue to see Figure 2 ,like Figure 2As shown, in some exemplary embodiments, the simulated load unit 402 includes a preset test resistor board configured to provide the core board 80 under test with a simulated load scenario from actual applications. Thus, dynamic testing of the PCBA core board is achieved through the preset test resistor board, which is highly versatile and can be used to test different PCBA core boards. It should be noted that this invention does not limit the load scenario provided by the preset test resistor board. For example, the load scenario includes current load, voltage fluctuation, etc. Correspondingly, the simulated load scenario provided by the preset test resistor board for the core board 80 under test includes: simulating loads corresponding to various scenarios in actual applications such as communication functions, control functions, and power supply functions of the core board 80 under test. More specifically, the preset test resistor board includes, but is not limited to, functional circuit boards formed by resistive devices, inductive devices, capacitors, and power devices. Preferably, the preset test resistor board can be a customized test resistor board assembly for testing the core board 80 under test, thereby simulating the load scenario of the core board 80 under test in actual application.

[0042] To avoid unnecessary details, the usage of the PCB module testing device 40 will not be elaborated here. Please refer to the section below for instructions on using the integrated PCB module production system.

[0043] Example 2

[0044] This embodiment provides an integrated PCB module production system. For an example, please refer to [link to example system]. Figure 4 and Figure 5 ,in, Figure 4 This is a block diagram of an integrated PCB module production system provided in one embodiment of the present invention. Figure 5 This is a schematic diagram of the core board and PCB board assembly structure of the workstation support module in an integrated PCB module production system according to one embodiment of the present invention. (See also...) Figure 4The integrated PCB module production system includes a workstation support module 10, a core board automatic assembly module 20 disposed around the workstation support module 10, a program burning module 30, and a PCB module testing device 40 as described in any of the above embodiments, as well as a transmission control module 50 and a result feedback module 60. The workstation support module 10 is configured to support a PCB board 70. The core board automatic assembly module 20 is configured to assemble a core board 80 to be tested onto the PCB board 70. The program burning module 30 is configured to burn a program onto the core board 80 to be tested. The PCB module testing device 40 is configured to perform FCT testing on the core board 80 to be tested and transmit the test results to the result feedback module 60. The transmission control module 50 can drive the workstation support module 10 to rotate, so as to realize the assembly, burning, and switching of the test station of the core board 80 to be tested. The result feedback module 60 is configured to provide feedback on the working status of the integrated PCB module production system and / or the test results.

[0045] The integrated PCB module production system provided by this utility model can carry the PCB board 70 and the core board 80 to be tested assembled on the PCB board 70 through the workstation support module 10. The core board automatic assembly module 20 can assemble the core board 80 to be tested onto the PCB board 70 carried by the workstation support module 10. The program burning module 30 can automatically burn the program to the core board 80 to be tested. The PCB module testing device 40 can perform dynamic testing on the core board 80 to be tested. The transmission control module 50 can switch the PCB board to be tested between the assembly, burning and testing workstations. The result feedback module 60 can monitor the results of each process in the integrated PCB module production system. Therefore, the integrated PCB module production system provided by this utility model can provide a fixed support platform for the PCB board 70 to ensure that the PCB board 70 does not shift during assembly, programming, and testing; the core board automatic assembly module 20 can automatically assemble the core board 80 to be tested onto the PCB board 70, avoiding damage to the PCB board 70 and the core board 80 to be tested during assembly, thereby improving assembly efficiency and accuracy; the automatic programming of the core board 80 to be tested improves the programming efficiency; and the system provides the core board 80 to be tested with dynamic simulations of actual applications. The system tests various scenarios to identify potential faults, improves early quality control, and effectively avoids subsequent equipment damage. The transmission control module 50 drives the workstation support module 10 to transfer the core board 80 under test through the three core processes of assembly, programming, and testing. This avoids secondary damage to the core board 80 during transfer and saves connection time between processes, thus adapting to the high-efficiency production requirements of automated production lines. By monitoring the working status and / or test results of the integrated PCB module production system throughout the entire process, the system ensures the smooth operation of each process and subsequent result traceability. In summary, the integrated PCB module production system provided by this invention, by integrating automatic core board assembly, programming, and dynamic FCT testing functions, can achieve high-precision, high-efficiency production and early quality control of PCBA core components, while also possessing the advantages of compact structure and strong adaptability.

[0046] For example, see Figure 5 ,like Figure 5As shown, in some exemplary embodiments, the workstation support module 10 includes a positioning fixture for fixing the PCB board 70. Thus, the positioning fixture enables precise positioning of the PCB board 70, facilitating the assembly, programming, and testing of the core board 80 under test. The method of automatically fixing the PCB board 70 to the positioning fixture ensures that the PCB board 70 remains stationary during assembly, programming, and testing. It should be noted that this invention does not limit the specific implementation of the positioning fixture. For example, the positioning fixture may include a customized high-precision positioning fixture, the surface of which may be provided with positioning pins or other positioning devices that match the positioning holes of the PCB board 70. Preferably, in some exemplary embodiments, the positioning fixture is detachable to better adapt to different PCBA specifications by replacing the positioning fixture. For example, in a specific embodiment of the PCB module integrated production system provided by this utility model, the positioning accuracy can reach ±0.02mm through the positioning pins provided on the surface of the positioning fixture that match the positioning holes of the PCB board 70.

[0047] Exemplary embodiments, in some of these exemplary implementations, include a pneumatic gripper (not shown), a displacement adjustment mechanism (not shown), and a pressure sensor (not shown). The pneumatic gripper grips the core board 80 to be tested. The displacement adjustment mechanism drives the pneumatic gripper to perform precise displacement along the X, Y, and Z axes via a drive motor. The pressure sensor detects the assembly pressure in real time. After assembly, the core board 80 to be tested is automatically fixed. Thus, by using the displacement adjustment mechanism to drive and control the pneumatic gripper, the core board 80 to be tested can be precisely assembled to the corresponding position on the PCB board 70, thereby improving the assembly efficiency and accuracy of the core board 80. The pressure sensor detects the assembly pressure in real time, thus preventing damage to the core board 80 and / or the PCB board 70 due to excessive pressure.

[0048] It should be noted that the present invention does not limit the specific implementation of the pneumatic gripper. For example, the pneumatic gripper can be a two-finger gripper, a three-finger gripper, etc. Furthermore, the present invention does not limit the specific implementation of the automatic fixation of the core board 80 to be tested on the PCB board 70 after assembly. For example, the fixation of the core board 80 to be tested on the PCB board 70 can be achieved by screw fastening or snap fastening, etc.

[0049] For example, please continue to see Figure 4 ,like Figure 4As shown, in some exemplary embodiments, the program burning module 30 includes a burning interface adapter (not shown) for connecting to the core board 80 under test and a data transmission unit (not shown) connected to the burning interface adapter. The data transmission unit is connected to a host computer. This invention connects one end of the burning interface adapter to the burning interface of the core board 80 under test, the other end of the burning interface adapter to one end of the data transmission unit, and the other end of the data transmission unit to the host computer, forming a data transmission link for burning the program, thereby automatically burning the program to the core board 80 under test. Thus, through the transmission link in the program burning module 30 provided by this invention, the program in the host computer is automatically burned into the core board 80 under test, thereby improving the efficiency of program burning to the core board 80 under test, and ensuring the integrity of program burning through real-time monitoring during the burning process.

[0050] It should be noted that this utility model does not limit the specific type of the programming interface of the core board 80 under test. For example, the type of programming interface includes, but is not limited to, USB, JTAG and UART. Correspondingly, the programming interface adapter can integrate interfaces including, but not limited to, USB, JTAG and UART. Thus, the programming interface adapter can be compatible with programming interfaces of different specifications of the core board 80 under test to adapt to different specifications of PCBA.

[0051] For example, in some exemplary embodiments, the relevant description of the PCB module testing device 40 can be found in the content about the PCB module testing device 40 in Embodiment 1 above, and will not be repeated here.

[0053] Therefore, this utility model, by placing the workstation support module 10 on the hollow rotary motor 501 and driving the workstation support module 10 to rotate through the hollow rotary motor 501, achieves the switching of the assembly, programming, and testing workstations for the core board 80 to be tested, thereby improving production efficiency; through the gear shaft transmission mechanism 502, the rotational accuracy when the hollow rotary motor 501 drives the workstation support module 10 to rotate can be improved, and the hollow rotary motor 501 and the gear shaft transmission mechanism 502 have a compact structure, further improving production efficiency while reducing the overall size of the device; through the slip ring 503, stable signal and power transmission is achieved when the workstation support module 10 rotates, ensuring the normal operation of the workstation support module 10 and the transmission control module 50, while avoiding cable entanglement between the workstation support module 10 and the transmission control module 50 during operation.

[0054] Preferably, the hollow rotary motor 501 has a hollow structure, its driving mechanism is a servo motor 505, the gear shaft transmission mechanism 502 includes gears, shafts, bearing seats and other mechanisms, the slip ring 503 is located below the transmission control module 50, and its end is fixed with a cable outlet fixing block.

[0056] In a specific implementation, the integrated PCB module production system provided by this utility model reduces the overall volume by 40% compared to traditional split-type equipment.

[0057] It should be noted that the drive mechanism of the hollow rotary motor 501 described in this utility model is not limited to the servo motor 505. Those skilled in the art can select a suitable drive motor according to the actual situation. At the same time, the components of the mechanism in the transmission control module 50 described in this embodiment are not all the components of the mechanism, and will not be described in detail here.

[0058] For example, please continue to see Figure 4 ,like Figure 4As shown, in some exemplary embodiments, the result feedback module 60 includes a display screen (not shown) and an alarm unit (not shown); the display screen is configured to display the working status of the integrated PCB module production system and / or the test results, and the alarm unit is configured to report any abnormalities in the working status and / or the test results. Thus, by providing feedback on the working status and / or test results of the integrated PCB module production system through the display screen and the alarm unit, not only can the assembly, programming, and testing processes of the core board 80 under test be controlled in real time, but data traceability of the core board 80 under test is also facilitated.

[0059] It should be noted that those skilled in the art should understand that this utility model does not limit the working status and / or test results of the integrated PCB module production system displayed on the screen. For example, the working status includes, but is not limited to, assembly progress, programming success rate, test parameters, etc., and the test results include, but are not limited to, qualified, unqualified, etc. Furthermore, this utility model does not limit the abnormal conditions of the working status and / or test results of the integrated PCB module production system fed back by the alarm unit.

[0060] To better understand this utility model, the following description is in conjunction with the appendix. Figure 1-5 The present invention provides a detailed description of the usage method of one specific embodiment of the PCB module integrated production system proposed in this invention.

[0061] In the PCBA core board production process, firstly, the PCB board 70 is placed on the positioning fixture 101 of the workstation support module 10, and the positioning fixture 101 is used to position and fix the PCB board 70 (see...). Figure 5 ).

[0062] Then, the transmission control module 50 drives the station support module 10 to rotate to the core board automatic assembly station. The core board automatic assembly module 20 assembles the core board 80 to be tested to the corresponding position of the PCB board 70 and fixes it to realize the assembly of the core board 80 to be tested.

[0063] Next, after the core board is assembled, the transmission control module 50 can drive the station support module 10 to rotate to the program burning station. The program burning module 30 then transmits the received burning program to the core board 80 under test, completing the program burning process for the core board 80.

[0064] Finally, after the program is burned, the transmission control module 50 drives the station support module 10 to rotate to the test station, so as to complete the FCT test of the core board 80 to be tested under the dynamic scene provided by the PCB module test device 40.

[0065] During assembly and testing, the working status and / or test results of the integrated PCB module production system can be obtained in real time through the result feedback module 60.

[0066] After a single PCB board 70 completes all processes, the workstation support module 10 is reset, waiting for the next PCB board 70 to be loaded.
