Description
Technical Field
[0001] This utility model belongs to the field of testing device technology, specifically relating to a power system board testing device. Background Technology
[0002] Currently, there are two methods for debugging various circuit boards in power systems, such as protection devices: one is to manually test the circuit boards using a debugging instrument; the other is to place a debugging cabinet at a fixed position on the production line and use a robot to automatically test the circuit boards.
[0003] Manual testing requires manually inserting and removing test chips and other debugging fixtures, which is time-consuming and labor-intensive. Furthermore, if testing is required at the production line, the debugging equipment must be moved to the line, resulting in low debugging efficiency. When using debugging cabinets and robots for automated testing, the cabinets are heavy and require precise positioning, leading to fixed placement and making it impossible to change the corresponding testing devices for different circuit board models. Summary of the Invention
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a power system board testing device that can flexibly and easily transport the testing equipment to the production line for line-side debugging, facilitate the testing of different models of boards under test, and eliminate the need for manual insertion and removal operations, resulting in high testing efficiency.

[0031] Example 1
[0032] like Figure 1 As shown, this embodiment provides a power system board testing device, including a movable cabinet 1, a test bench 15, and a board carrier 8.
[0033] like Figure 1 and Figure 4As shown, the cabinet 1 houses the testing equipment, and casters 4 are installed at the four corners of the bottom of the cabinet 1 for easy and flexible movement of the testing equipment. Height-adjustable support legs 14 are also installed at the four corners of the bottom of the cabinet 1. When the cabinet 1 is moved to a suitable position, the support legs 14 can support the cabinet 1 and prevent the cabinet 1 from moving during the testing process.
[0034] like Figure 4 As shown, the cabinet 1 has a cavity for storing the testing equipment and a safety door 5 for sealing the cavity. The safety door 5 is located on the back of the cabinet 1. In this embodiment, the safety door 5 is a double door type, used to protect the testing equipment, such as a debugging instrument, inside the cabinet 1.
[0035] like Figure 1 and Figure 3 As shown, the upper part of the cabinet 1 is provided with an operating table 2, and the surface of the operating table 2 is provided with at least one test table 15. In this embodiment, the surface of the operating table 2 is provided with two test tables 15, forming a dual-station test structure, which facilitates the improvement of test efficiency.
[0036] like Figure 1 and Figure 2 As shown, the test bench 15 is slidably connected to the circuit board carrier 8, which is used to place the circuit board to be tested. Specifically, the circuit board carrier 8 includes a base plate 81 and a platform 82 connected to the base plate 81. The surface of the test bench 15 is provided with at least one track 3. In this embodiment, two tracks 3 are provided. The lower surface of the base plate 81 is equipped with track wheels 83 that match the tracks 3 to facilitate the movement of the circuit board carrier 8.
[0037] In some other embodiments, such as Figure 2 As shown, a handle 84 is installed at one end of the base plate 81 to facilitate pushing and pulling the plate carrier 8.
[0038] In some other embodiments, such as Figure 2 As shown, the test bench 15 is also provided with a limiting block 13 located at the end of the track 3, which is used to limit the limit of the plate carrier 8.
[0039] like Figure 2 and Figure 3 As shown, the board carrier 8 has a test pin 9 and an SD card slot 10 on its platform 82. An SD card is installed in the SD card slot 10, and the SD card slot 10 is electrically connected to the test pin 9. When the board under test contacts the test pin 9, the SD card in the SD card slot 10 can directly download the test program to the board under test.
[0040] like Figure 1 and Figure 2As shown, a roller gantry 7 for fixing the board carrier 8 and the board under test is installed on the test bench 15. Multiple roller gantry 7s are symmetrically distributed on both sides of the board carrier 8. Each roller gantry 7 includes a fixing block 71, an L-shaped block 72 connected to the fixing block 71, and rollers 73 connected to the L-shaped block 72. The fixing block 71 is installed on the test bench 15.
[0041] In some other embodiments, the vertical and horizontal bars of the L-shaped block 72 can be configured as a telescopic structure to accommodate test boards of different sizes.
[0042] like Figure 1 and Figure 2 As shown, a wiring harness 11 is also installed on the test bench 15. The wiring harness 11 is connected to the test equipment. The wiring harness 11 is correspondingly arranged with the board carrier 8 and can be connected to the board under test. In this embodiment, the wiring harness 11 is located at one end of the track 3 and is directly opposite the board carrier 8, which facilitates docking and plugging with the board under test.
[0043] like Figure 1 As shown, the side of the cabinet 1 is provided with a DC power interface 6 for connecting to an external DC power supply via a DC power connection; the front of the cabinet 1 is provided with an LCD screen 12, and the DC power interface 6 and the LCD screen 12 are electrically connected to the test equipment respectively. The LCD screen 12 is used to display the test results, making it convenient for testers to read the test results.
[0044] The working principle of the power system board testing device provided in this embodiment is as follows:
[0045] The operator moves cabinet 1 to the edge of the production line, places the board under test onto the platform 82 of the board carrier 8, and pushes the board carrier 8 forward. During the pushing process, the board carrier 8 is positioned by the roller gantry 7, so that the test pin 9 contacts the board under test. The SD card in the SD card slot 10 downloads the test program to the board under test. At the same time, the board under test is connected to the wiring dock 11. The board under test is powered on and the automatic test is started. The test results are observed through the LCD screen 12. Then, the operator pulls the handle 84 of the board carrier 8 to disconnect the tested board from the wiring dock 11, and the test ends.
[0046] This utility model adopts a movable cabinet 1, with the testing equipment housed inside. This allows for flexible and convenient transport of the testing equipment to the production line for on-line debugging, facilitating the testing of different models of circuit boards. A circuit board carrier 8 is slidably connected to the testing table 15, which is equipped with a roller gantry 7. During testing, the circuit board to be tested is placed on the circuit board carrier 8, and the carrier 8 is pushed to fix the carrier 8 and the circuit board to be tested in place by the roller gantry 7. Simultaneously, the circuit board to be tested connects to the connector 11, entering automatic testing. This eliminates the need for manual plugging and unplugging, improving testing efficiency and solving the problem of testing speed lagging behind due to the fast production cycle of the assembly line. Furthermore, an operating table 2 is located on the upper part of the cabinet 1, with at least one testing table 15 on its surface. By setting multiple testing tables 15, testing of circuit boards at multiple workstations can be achieved, further improving testing efficiency and thus enhancing product production efficiency.
[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
