Description

Technical Field

[0001] This utility model belongs to the field of motherboard testing technology, and in particular relates to an automatic testing device for interconnected PCBA motherboards. Background Technology

[0002] In the manufacturing process of electronic and electrical products, the printed circuit board assembly (PCBA) is a core component, and its functional and performance reliability is crucial. Therefore, testing is indispensable in the production process. Currently, the industry's conventional testing method for PCBA motherboards mainly relies on manual operation: operators must remove the motherboards to be tested one by one from the running production line and manually place them on independent test fixtures or test benches for functional testing. After testing, the motherboards are then manually returned to the production line to continue flowing. This traditional model has significant limitations. First, frequent manual handling greatly limits overall testing efficiency, becoming a bottleneck for improving production cycle time. Second, this process is highly dependent on manual labor, not only consuming a large amount of human resources and increasing production costs, but also affecting the consistency of testing and product yield due to errors or electrostatic damage risks introduced by human operation. More importantly, this offline testing method forces the production line to be interrupted or slowed down to adapt to the testing rhythm, seriously disrupting the continuity and automation of production, making it difficult to meet the needs of modern efficient and automated manufacturing.

[0003] Therefore, there is an urgent need for a wired PCBA motherboard automatic testing device with low labor costs and high testing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an inline PCBA motherboard automatic testing device that can quickly, automatically, and reliably complete testing without interruption or separation from the main production line.

[0034] See appendix Figure 1 To be continued Figure 6 The figure shows a specific embodiment of the inline PCBA motherboard automatic testing device provided by this utility model.

[0035] See appendix Figure 1 and attached Figure 2 The wired PCBA motherboard automatic testing equipment includes:

[0036] The frame 1 has a feed inlet and a discharge outlet on both sides;

[0037] The assembly line 2 is installed in the rack 1. The assembly line 2 is connected from the inlet to the outlet and is used to transport the PCBA motherboard 12 to be tested.

[0038] A fixture box 3 is located below the assembly line component 2, and a lower mold component 310 is provided on the fixture box 3.

[0039] The first drive mechanism 4, which is connected to the production line assembly 2, is used to drive the production line assembly 2 to move downward so that the PCBA motherboard 12 under test is connected to the lower mold assembly 310.

[0040] The upper mold assembly 5 and the second drive mechanism 6 are located above the assembly line assembly 2. The second drive mechanism 6 is used to drive the upper mold assembly 5 to move downward to perform a pressure connection test on the PCBA motherboard 12 under test.

[0041] See appendix Figure 1 and attached Figure 2 In the above embodiment, the frame 1 is the overall outer frame of the equipment. The frame 1 has an openable window on the front, and a display screen for viewing test results, facilitating operator monitoring of the testing process. The inlet and outlet are located on the left and right sides of the frame 1, respectively. The assembly line component 2 passes through the inlet and outlet within the frame 1, connecting to the main production line. When the PCBA motherboard 12 under test is transported to the assembly line component 2 through the inlet and aligns with the lower mold component 310, the first drive mechanism 4 drives the assembly line component 2 to descend and align with the upper mold component 310. Then, the second drive mechanism 6 drives the upper mold component 5 to press down, achieving automatic upper and lower mold connection testing of the PCBA motherboard 12 on the assembly line without manual handling, significantly improving testing efficiency and continuity. In this embodiment, the first drive mechanism 4 and the second drive mechanism 6 are cylinders.

[0042] See appendix Figure 3 and attached Figure 4 In the above embodiment, the frame 1 is provided with a platform 7, and the platform is provided with a sliding rail 710. The fixture box 3 is detachably installed below the production line assembly 2 via the sliding rail 710. In this embodiment, the fixture box 3, the production line assembly 2, the upper mold assembly 5, and other structures are located above the platform 7, and the area below the platform 7 is used to place various electrical control components. The fixture box 3 can be slid out through the window at the front of the frame 1 in a pull-out manner. After replacing the fixture box 3, it can be slid in and installed below the production line assembly 2 in a push-in manner. This facilitates flexible switching of the test fixture box 3 according to different PCBA motherboard types, improving the compatibility of the test equipment.

[0043] See appendix Figure 5 and attached Figure 6In the above embodiment, the platform 7 is provided with a locking mechanism 8, which is used to lock the fixture box 3 below the assembly line component 2. The locking mechanism 8 includes a locking pin 810 and a third drive mechanism 820 connected to the locking pin 810. The lower end of the fixture box 3 is provided with a locking hole 320, and the third drive mechanism 820 is used to drive the locking pin 810 into the locking hole 320. In this embodiment, after the fixture box 3 is slid into place below the assembly line component 2, the third drive mechanism 820 drives the locking pin 810 upward from below the platform 7 and into the locking hole 320 at the bottom of the fixture box 3. The locking pin 810 keeps the fixture box 3 locked in a fixed state, ensuring accurate alignment and preventing misalignment or accidental removal during testing. In this embodiment, the third drive mechanism 820 is a cylinder.

[0044] See appendix Figure 5 and attached Figure 6 In the above embodiment, the fixture box 3 has an output connector 330 at its rear end, and the platform 7 has an adapter board assembly 9. When the fixture box 3 is slidably installed below the production line assembly 2, the adapter board assembly 9 is used to connect to the output connector 330 to transfer the test signal output from the fixture box 3. In this embodiment, by using the output connector 330 to connect to the adapter board assembly 9, the signal can be seamlessly transmitted to the back-end testing system. By replacing different adapter board assemblies 9, the signal can be transferred to different testing instruments, increasing the versatility of the equipment.

[0045] See appendix Figure 6 In the above embodiment, the adapter plate assembly 9 includes an adapter plate 910 and a fourth drive mechanism 920. The fourth drive mechanism 920 is used to drive the adapter plate 910 to translate and align with the output connector 330. In this embodiment, after the fixture box 3 is slid into place below the assembly line assembly 2, the fourth drive mechanism 920 drives the adapter plate 910 to translate and align with the output connector 330 at the rear end of the fixture box 3, achieving precise automatic alignment between the adapter plate 910 and the output connector 330 of the fixture box 3. This avoids the tediousness and error risk of manually plugging and unplugging cables, reducing human intervention. In this embodiment, the fourth drive mechanism 920 is a cylinder.

[0046] See appendix Figure 3 and attached Figure 4In the above embodiment, the production line assembly 2 includes a first guide rail 210 and a second guide rail 220 arranged in parallel. An adjustment component 10 is provided across the first guide rail 210 and the second guide rail 220 near the inlet and outlet. The adjustment component 10 is used to adjust the distance between the first guide rail 210 and the second guide rail 220. In this embodiment, the adjustment component 10 allows for flexible adjustment of the distance between the first guide rail 210 and the second guide rail 220, enabling the equipment to adapt to PCBA motherboards of different widths, thus improving the equipment's versatility and compatibility. In this embodiment, the telescopic rod of the first drive mechanism 4 is connected to the lower part of the adjustment component 10, ensuring that the first drive mechanism 4 maintains a stable distance between the first guide rail 210 and the second guide rail 220 simultaneously when driving the entire production line assembly 2 to descend.

[0047] See appendix Figure 3 and attached Figure 4 In the above embodiment, a side-insertion assembly 11 is also provided below the pipeline assembly 2.

In this embodiment, the side-insertion assembly 11 has a detachable structure, which facilitates the replacement of different side-insertion assemblies 11 according to different types of PCBA motherboards 12 under test. Before testing, the side-insertion assembly 11 is located below the two guide rails of the pipeline assembly 2. During the test, the first drive mechanism 4 drives the pipeline assembly 2 to move downward. At this time, the side-insertion assembly 11 will be between the first guide rail 210 and the second guide rail 220. Then, it can be inserted into the side interface of the PCBA motherboard by lateral displacement.

[0048] See appendix Figure 3 and attached Figure 4 In the above embodiment, the production line assembly 2 is further provided with a pressure plate assembly 230, which presses the PCBA motherboard 12 under test onto the production line assembly 2. In this embodiment, when the PCBA motherboard 12 under test is transported on the production line assembly 2 to the test position located between the upper mold assembly 5 and the lower mold assembly 310, the pressure plate assembly 230 presses the PCBA motherboard 12 under test onto the production line assembly 2 for fixation, preventing the motherboard from shifting or loosening during the downward movement, ensuring accurate and smooth docking with the lower mold assembly 310, and guaranteeing the stability of the test connection and the reliability of the results.

[0049] In summary, this embodiment provides an inline PCBA motherboard automatic testing equipment. By setting a production line assembly 2 that runs through the inlet and outlet within the frame 1, and configuring an upper mold assembly 5 and a lower mold assembly 310 above and below it respectively, the PCBA motherboard 12 under test can automatically complete the upper and lower mold connection test on the production line without manual handling. By setting a sliding rail 710 on the platform 7 of the frame 1, the fixture box 3 can be disassembled and replaced, facilitating flexible switching of test fixtures according to different PCBA motherboard types. By connecting an adapter board assembly 9 to the rear end of the fixture box 3, seamless signal transmission to the back-end testing system is facilitated. By setting adjustable spacing adjustment components 10 at both ends of the parallel guide rail of the production line assembly 2, the equipment can adapt to PCBA motherboards of different widths. This embodiment can complete testing quickly, automatically, and reliably without interruption or separation from the main production line, achieving seamless integration of the PCBA motherboard testing process, optimizing the production process, reducing labor costs, and improving testing efficiency and product quality.

[0050] The embodiments described above are merely one of the preferred embodiments of this utility model.
