[0031] like Figure 1 - Figure 3 As shown, the present application provides a PCBA functional testing device 1, comprising:

[0032] The machine 10 includes a box body 11 and a connecting plate 13 connected to the upper portion of the box body 11. The connecting plate 13 extends in a vertical direction.

[0033] The testing mechanism 30 includes a first driving member 31 and a burning test fixture 33. The first driving member 31 is connected to the connecting plate 13. The first driving member 31 drives the burning test fixture 33 to drive the burning test fixture 33 to move back and forth in the vertical direction. The burning test fixture 33 has at least two test positions 331, which are used to test PCBA components.

[0034] The mounting mechanism 50 includes a second driving member 51, a mounting seat 53, and a test workpiece 55. The second driving member 51 is connected to the box 11. The second driving member 51 drives the mounting seat 53 to drive the mounting to reciprocate in the horizontal direction. The test workpiece 55 is connected to the mounting seat 53. The test workpiece 55 is provided with at least two placement positions 551. The placement positions 551 are used to place PCBA components. A placement position 551 and a test position 331 are located on a vertical plane and correspondingly arranged.

[0035] The starting mechanism 70 includes a third driving member 71 and a starting seat 73. The third driving member 71 is connected to the box 11 and is located below the test mechanism 30. The third driving member 71 drives the starting seat 73 to drive the starting seat 73 to move back and forth in the horizontal direction. The starting seat 73 is provided with at least two starting members 731. The starting member 731 is used to press the PCBA component button. A starting member 731 and a test position 331 are located on the vertical plane and correspondingly arranged.

[0036] In the present application, it can be understood that the first driving member 31, the second driving member 51 and the third driving member 71 can be a cylinder, an oil cylinder, etc., or a combination of a motor and a screw rod, or a combination of a gear and a rack, which is not limited here.

[0037] The number of test positions 331 is at least two, and can be two, three, four, five, etc., which is not limited here. Correspondingly, the number of placement positions 551 and starting members 731 can also be two, three, four, five, etc., which is not limited here. At least two test positions 331 are set at intervals, and can be set at intervals along the same extension direction of the burn test fixture 33, or can be arranged in a matrix. One test position 331 is responsible for performing burn detection on the PCBA component of one placement position 551. The placement position 551 can be in the shape of a groove, a raised clip, or a flat-set locking structure, which is not limited here. The placement position 551 can limit and fix the placement position 551 of the PCBA component to prevent it from shifting and shaking, thereby ensuring the effectiveness and accuracy of the burn detection. An opening is provided on one side of the placement position 551, and the button of the PCBA component can be exposed at the opening to facilitate pressing of the starting member 731.

[0038] The steps of the burn test are as follows: a robot or a human hand places the PCBA component on the placement position 551 of the test workpiece 55. One or more placement positions 551 can be placed. The first driving member 31 is started to drive the mounting seat 53 to move toward the bottom of the burn test fixture 33. After reaching the bottom of the burn test fixture 33, the third driving member 71 is started to drive the starting seat 73 to move toward the mounting seat 53. The starting member 731 presses the PCBA component button to start the PCBA component. After starting, the second driving member 51 is turned on to drive the burn test fixture 33 to move downward so that the test position 331 is electrically connected to the PCBA component button, and the burn test can be started. After the test is completed, the second driving member 51 drives the burn test fixture 33 to return to its position, and the first driving member 31 drives the mounting seat 53 to return to its position. The robot or the human hand removes the PCBA component from the test workpiece 55 to complete the burn test.

[0039] The above technical solution provided by the embodiment of the present application has the following advantages over the prior art: the present application is provided with at least two test positions 331 located in the test mechanism 30, and the test positions 331 can be used for the burn-in test of the PCBA component, and at least two placement positions 551 are provided in the installation mechanism 50, and the placement positions 551 can be used for the placement of the PCBA component. A starting mechanism 70 is also provided on one side of the installation mechanism 50, and the starting mechanism 70 is provided with at least two starting members 731, and the starting members 731 can be used to press the button of the PCBA component to start the PCBA component. After the PCBA component is placed in the placement position 551, the installation mechanism 50 is moved to the bottom of the test mechanism 30, and the starting mechanism 70 moves to press the button to start the PCBA component. The test mechanism 30 is pressed down to perform the burn-in test. After the test is completed, the installation mechanism 50 returns to its original position, and the burn-in test process is completed. The present application realizes the simultaneous detection of multiple PCBA components, thereby improving the capacity and detection efficiency of the test device.

[0040] Furthermore, at least two test positions 331 are spaced apart along the extension direction of the burn-in test fixture 33.

[0041] In the design of the burn test fixture 33, we intentionally set up at least two test positions 331, and these test positions 331 are spaced apart along the extension direction of the fixture. This layout avoids interference between different chips, not only optimizing the test process but also improving test efficiency. Each test position 331 is equipped with advanced burn equipment and precise testing instruments to ensure that the burn test of each chip can be completed accurately and flawlessly. In practical applications, this design enables the test fixture to handle multiple chips or devices simultaneously, greatly improving test efficiency. In addition, this design also has a certain degree of flexibility and can be adjusted and optimized according to different testing requirements. For example, the number of test positions 331 can be increased or decreased as needed, or the spacing between test positions 331 can be adjusted to accommodate chips or devices of different specifications and sizes. By designing at least two test positions 331 spaced apart along the extension direction of the burn test fixture 33, we can not only improve test efficiency but also ensure the accuracy and reliability of the test.

[0042] Furthermore, a plurality of upper microneedles 3311 are provided at the output end of each test position 331. The upper microneedles 3311 provided at the output end of each test position 331 have been precisely designed and manufactured to ensure that stable and accurate signal output can be provided during the test process. These upper microneedles 3311 not only have extremely small sizes, which can accurately correspond to the contact points of the components to be tested, but also have excellent conductive properties, ensuring efficient signal transmission. During the test process, the upper microneedles 3311 transmit the signal to the test equipment through contact with the components to be tested. Its precise positioning and stable contact make the test data more accurate and reliable. At the same time, these upper microneedles 3311 also have excellent wear resistance and corrosion resistance, and can maintain good performance even during long-term tests.

[0043] Furthermore, the housing 11 forms a receiving cavity 111 with an opening at the top, and the second driving member 51 is arranged in the receiving cavity 111. The mounting mechanism 50 also includes a slide rail 57 and a slider 59. The slide rail 57 is arranged on the upper surface of the housing 11. One end of the slider 59 is slidably connected to the mounting seat 53, and the other end is connected to the mounting seat 53. The second driving member 51 drives the mounting seat 53 to move back and forth along the extension direction of the slide rail 57. During the reciprocating movement of the mounting seat 53 along the slide rail 57, the housing 11 serves as a stable support for the entire mechanism, ensuring smooth and accurate movement. The existence of the receiving cavity 111 not only provides installation space for the second driving member 51, but also provides necessary protection and isolation for its operation, preventing external factors from interfering with or damaging the driving member. The design of the slide rail 57 ensures that the movement trajectory of the mounting seat 53 is stable and accurate. The slide rail 57 is closely connected to the upper surface of the housing 11, providing a smooth sliding path for the slider 59. One end of the slider 59 is connected to the mounting base 53, and the other end is connected to the second driver 51, allowing the second driver 51 to precisely control the movement of the mounting base 53. Upon activation of the second driver 51, the mounting base 53 begins to reciprocate along the extension of the slide rail 57. This type of movement is suitable for both simple linear motion and more complex motion paths through programmable control. This allows for flexible and accurate positioning of various components or devices on the mounting base 53, greatly facilitating subsequent operation or installation.

[0044] Furthermore, the mounting base 53 is provided with a clearance opening 531. The starting mechanism 70 is located on the mounting base 53 and is arranged corresponding to the clearance opening 531. The starting base 73 is spaced relative to the mounting base 53. The clearance opening 531 on the mounting base 53 is cleverly designed, facilitating the smooth operation of the starting mechanism 70. The precise alignment of the starting mechanism 70 with the clearance opening 531 ensures precise and stable operation. At the same time, an appropriate spacing is maintained between the starting base 73 and the mounting base 53, ensuring the flexible movement of the starting mechanism 70 while avoiding unnecessary friction and collisions. The activation mechanism 70 creates an efficient working linkage between the mounting base 53 and the starting base 73. When the activation mechanism 70 is activated, it quickly interacts with the corresponding component on the mounting base 53 through the clearance opening 531, thereby achieving the desired function. This design not only improves operational efficiency but also reduces the failure rate, providing a strong guarantee for the stable operation of the entire system. Furthermore, the spacing between the mounting base 53 and the starting base 73 also takes into account heat dissipation and maintenance convenience. Proper spacing ensures that the heat generated by the starting mechanism 70 during operation is effectively dissipated, avoiding performance degradation or damage due to overheating. At the same time, this also facilitates subsequent maintenance and repair, allowing staff to easily inspect and repair the starting mechanism 70.

[0045] Furthermore, there are two slide rails 57 and multiple sliders 59. The two slide rails 57 are respectively arranged on both sides of the avoidance opening 531 in the driving direction of the second driving member 51. Multiple sliders 59 are spaced apart and connected to one side of the mounting seat 53. Multiple sliders 59 on the same side are correspondingly slidably connected to one slide rail 57. The number of slide rails 57 is set to two, while the number of sliders 59 is multiple. The two slide rails 57 are precisely arranged on both sides of the avoidance opening 531 to ensure that they match the driving direction of the second driving member 51. Multiple sliders 59 are carefully spaced apart and firmly connected to one side of the mounting seat 53 to achieve stable structural support. It is worth noting that a precise sliding connection relationship is established between the sliders 59 on the same side and the slide rails 57. Each slider 59 corresponds to a slide rail 57. This one-to-one correspondence ensures the accuracy and reliability of the sliding process, while optimizing the stability and mechanical efficiency of the overall structure.

[0046] Furthermore, a guide member 333 is provided on the side of the burn test jig 33 facing the mounting base 53. A guide hole 533 is provided on the side of the mounting base 53 facing the burn test jig 33. As the burn test jig 33 is lowered, the guide member 333 is inserted into the guide hole 533. In this embodiment, as the burn test jig 33 is lowered, the guide member 333 precisely inserts into the guide hole 533, ensuring precise alignment and a secure connection between the jig and the mounting base 53. This design not only simplifies the operation process and improves installation efficiency, but also effectively prevents burn test errors caused by positioning deviations. As the guide member 333 is inserted into the guide hole 533, the contact surface between the jig and the mounting base 53 gradually increases, forming a stable support structure. This structure effectively dissipates the pressure and vibration generated by the jig during operation, ensuring the accuracy and stability of the burn test. Furthermore, the design of the guide member 333 and guide hole 533 takes into account the reuse of the jig and the durability of the mounting base 53. The guide member 333 is made of a highly wear-resistant material and can withstand multiple insertions and removals without being easily damaged; while the guide hole 533 adopts precision processing technology to ensure the accuracy and consistency of the aperture, allowing the fixture to be easily inserted and remain stable.

[0047] Furthermore, the mounting base 53 is provided with a plurality of guide members 333, the plurality of guide members 333 being spaced apart, and the mounting base 53 is provided with a plurality of guide holes 533. When the mounting base 53 descends, one guide member 333 is correspondingly inserted into one guide hole 533. In this embodiment, as the mounting base 53 continues to descend, each guide member 333 is sequentially inserted into the corresponding guide hole 533, just as a key is inserted into a lock with the same precision and stability. The coordination of the plurality of guide members 333 and the guide holes 533 not only ensures the stability of the mounting base 53 during its descent, but also enhances the accuracy and reliability of the overall structure. This design cleverly combines the stability and flexibility of the mechanical structure, allowing the mounting base 53 to remain stable during its descent while being precisely positioned at the predetermined position. As the mounting base 53 continues to descend, the coordination between the guide members 333 and the guide holes 533 becomes increasingly tight, and the mounting base 53 gradually approaches its final installation position. During this process, the forces interacting with each other gradually increase. However, thanks to the precise fit between the guide members 333 and the guide holes 533, these forces are effectively dispersed and balanced, ensuring a smooth installation process. When the mounting base 53 finally reaches its intended position, all guide members 333 are fully inserted into their corresponding guide holes 533, forming a stable and reliable overall structure. At this point, the mounting base 53 has completed its descent and is accurately positioned in the intended installation location. This design not only improves installation efficiency and accuracy, but also reduces risks and errors during the installation process, providing a solid foundation for subsequent use and maintenance.

[0048] Furthermore, a plurality of positioning members 553 are provided on the side of the test workpiece 55 facing the mounting base 53. These positioning members 553 are spaced apart. The mounting base 53 is provided with positioning holes 535. The test workpiece 55 is connected to the mounting base 53, with each positioning member 553 inserted into a corresponding positioning hole 535. To ensure a stable connection between the test workpiece 55 and the mounting base 53, each positioning member 553 is precisely designed, with its shape and size matching the positioning hole 535. The tight fit between the positioning members 553 and the positioning holes 535 ensures accurate installation and effectively prevents the test workpiece 55 from shaking during installation. During installation, the test workpiece 55 is gently placed on the mounting base 53. The operator then aligns each positioning member 553 with the positioning hole 535 and gently inserts them. Once all positioning members 553 are in place, a stable, integrated structure is formed between the test workpiece 55 and the mounting base 53. This design not only simplifies the installation process and improves installation efficiency, but also ensures the accuracy of the test workpiece 55. During subsequent use, the test workpiece 55 can be stably fixed on the mounting base 53, providing reliable support for subsequent testing work.

[0049] Furthermore, the upper surface of the housing 11 is equipped with multiple stops 113, located on either side of the mounting base 53 in the direction of movement. These stops 113 are used to limit the range of movement of the mounting base 53. Furthermore, the upper surface of the housing 11 features a sophisticated guide rail system to ensure stability and smoothness during movement of the mounting base 53. Made of wear-resistant material and precision-machined, the guide rail system boasts exceptional durability and precision. These rails not only provide the necessary support for the movement of the mounting base 53 but also effectively absorb vibration and shock, ensuring stable operation of the device. Stops 113 are located on either side of the mounting base 53 in the direction of movement. Made of high-strength material and specially treated to withstand the significant impact forces generated by the mounting base 53 during movement, they also effectively prevent the mounting base 53 from exceeding its predetermined range of movement. The shape and dimensions of the stops 113 are precisely calculated to ensure they precisely mate with the mounting base 53, providing a precise limiter function. In addition to the stopper 113 and the guide rail system, the interior of the housing 11 is also equipped with advanced sensors and a control system. These sensors monitor the position and movement of the mounting base 53 in real time and feed this data back to the control system. Based on this data, the control system precisely controls the movement of the mounting base 53, ensuring that it moves along the predetermined trajectory and speed.
