Technical Field

[0001] This utility model relates to the field of circuit control board testing, and more specifically to a control board testing fixture. Background Technology

[0002] Control board testing is a technical activity involving various devices and application scenarios, aiming to ensure the normal operation and functional integrity of the control board. Control board testing typically requires the use of specialized testing instruments such as multimeters, oscilloscopes, and signal generators.

[0003] For example, in the field of industrial automation, the proper functioning of a control board is determined by measuring electrical parameters such as power input voltage, capacitance, and resistance. However, conventional control board testing involves manually connecting the contacts of the board to be tested. During manual testing, the control board is prone to misalignment, leading to slow testing efficiency, large errors in test results, and unstable contact connections. Furthermore, the output signal for determining whether a test is successful is relatively small, making observation and judgment difficult. Utility Model Content

Detailed Implementation

[0021] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0022] See details Figure 1 , Figure 2 A detailed example of using a fixed control board for testing is provided below:

[0023] A control panel testing fixture includes a control console 11 and multiple reciprocating rods 19 slidably connected to the control console 11. Each reciprocating rod 19 has a support frame 17 with a support hole 18 in its center. A stand 21 is fixedly connected to the control console 11. A handle 22 is rotatably connected to the upper part of the stand 21, and a connecting rod 23 is rotatably connected to the lower part of the handle 22. A pressure rod 24 is rotatably connected to the lower part of the connecting rod 23. A guide tube 25 is fixedly connected to the stand 21 to restrict the sliding of the pressure rod 24. A pressure plate 27 is fixedly connected to the lower part of the pressure rod 24. Multiple ejector pins 28 and multiple insertion pins 29 are fixedly connected to the lower part of the pressure plate 27. A button 31 corresponding to the multiple insertion pins 29 is provided on the upper part of the pressure plate 27.

[0024] When testing the control board, it is placed in the support hole 18. The support hole 18 on the support frame 17 limits the position of the control board, ensuring the accurate positioning of the electronic components on the control board. After placing the control board, the handle 22 is manually turned downwards. The rotation of the handle 22 drives the upper end of the connecting rod 23 to move, thereby changing the position of the lower part of the connecting rod 23. The lower part of the connecting rod 23 pushes the pressure rod 24 to move. The pressure rod 24 can only slide under the limit of the guide tube 25, thus ensuring the lifting and lowering of the pressure rod 24.

[0025] The pressure rod 24 drives the pressure plate 27 to descend, and the pressure plate 27 drives multiple ejector pins 28 to press down on the control board. The multiple ejector pins 28 have a positioning effect, preventing misalignment of the control board during fixing and ensuring its fixing accuracy. During the descent of the pressure plate 27, multiple pins 29 contact and connect with the control board, preparing for testing. Buttons 31 on the multiple pins 29 control whether they are connected, preparing for testing the control board. By corresponding the positions of the multiple pins 29 with the electronic components on the control board, the parameters of the control board to be tested are set specifically, and the performance of the control board is tested by pressing multiple buttons 31. After testing, the handle 22 is manually rotated upwards. The handle 22 pulls the pressure rod 24 upwards via the connecting rod 23. The pressure rod 24 drives the pressure plate 27 upwards, causing the pressure plate 27 to release its pressure on the control board, allowing the control board to be removed for testing of the next control board.

[0026] refer to Figure 1 Detailed embodiments to ensure the stability of the pressure plate 27 during lifting and lowering:

[0027] The control console 11 is fixedly connected with guide rods 26 that are slidably connected to the pressure plate 27. There are at least two guide rods 26, which can limit the pressure plate 27. The guide rods 26 can further limit the pressure plate 27 under the limit of the pressure rod 24 by the guide tube 25, thereby ensuring that the pressure plate 27 is further guided during the process of the pressure rod 24 driving the pressure plate 27 to rise and fall, and ensuring the stability of the sliding of the pressure plate 27.

[0028] refer to Figure 1 A detailed embodiment of manually rotating the handle 22 to raise and lower the pressure rod 24 is described below:

[0029] The handle 22 is L-shaped, with its long end serving as a handle and its short end rotatably connected to the support frame 21. When the handle 22 is manually rotated, the short end of the handle 22 rotates, changing the height of the lower part connected to the connecting rod 23. The lower part of the connecting rod 23 adjusts the height of the pressure rod 24, thereby allowing the pressure rod 24 to drive the pressure plate 27 to adjust its height. This adjustment of the pressure plate 27 then allows for the fixing and releasing of the control plate.

[0030] refer to Figure 1 Detailed embodiments to ensure that the position transmission between the handle 22 and the pressure rod 24 does not interfere:

[0031] There are two connecting rods 23, which are rotatably connected from both sides of the handle 22 and the pressure rod 24. This ensures that the connecting rods 23 do not obstruct the rotation path of the handle 22 during its upward and downward rotation, thus preventing interference and ensuring that the pressure rod 24 can change its position vertically during the rotation of the handle 22.

[0032] refer to Figure 1 and Figure 2 Detailed embodiments of the stability control board;

[0033] Multiple ejector pins 28 are made of insulating material. This allows them to be inserted into through holes on the control board for positioning during downward movement without any electrical current being supplied, thus ensuring precise positioning and stable sliding of the control board.

[0034] refer to Figure 1 and Figure 2 A detailed embodiment of a detection instrument that displays information via multiple buttons 31 on the detection control board is described below:

[0035] Multiple pins 29 are made of conductive material. Thus, when multiple buttons 31 are pressed, the circuit of the detection control board can be connected or disconnected, thereby enabling the detection of the control board through multiple buttons 31 and corresponding multiple pins 29.

[0036] refer to Figure 1 The following details an embodiment that increases the travel of the support frame 17 to ensure the control panel is securely fixed:

[0037] Springs are installed between the lower parts of multiple reciprocating rods 19 and the control console 11. When the pressure plate 27 presses down on the control board, it presses down onto the support frame 17. The support frame 17 then causes the reciprocating rods 19 to slide downwards, compressing the corresponding springs. The springs push the reciprocating rods 19 and the support frame 17, ensuring communication between the control board and the multiple pins 29. This allows the control board to be fixed while simultaneously preparing for testing. After testing the control board, the pressure plate 27 is lifted, and the compressed springs push the reciprocating rods 19 and the support frame 17 back to their original positions, ready for the next control board fixing and testing.

[0038] refer to Figure 2 A detailed embodiment of fixing the control board and connecting multiple pins 29 is provided:

[0039] The lower sides of the multiple ejector pins 28 are lower than the lower sides of the multiple pins 29. The multiple ejector pins 28 correspond to multiple through holes on the control board, while the multiple pins 29 correspond to the solder joints of the electronic components on the control board to be tested. Therefore, the plane of the multiple ejector pins 28 pressing down on the control board is lower than the plane of the multiple pins 29 contacting the control board, thereby ensuring that when the multiple ejector pins 28 press down on the control board, the multiple pins 29 are connected to the control board, which facilitates the selection and activation of the detection function of the control board to be tested via the button 31.

[0040] refer to Figure 1 A detailed embodiment of the stable sliding of the pressure rod 24 is provided below:

[0041] The guide tube 25 is a round tube with a groove. The pressure rod 24 is a round rod that mates with the guide tube 25, so that it can slide stably within the guide tube 25 when the pressure rod 24 is under force, thereby ensuring the stability of the movement of the pressure plate 27.

[0042] refer to Figure 1 , Figure 2 Detailed implementation of the detection control board:

[0043] The control panel 11 is equipped with a power switch 12, a temperature control knob 13, and a voltage display meter 14. The power switch 12 controls the connection and disconnection of the power supply, enabling power control of the control panel 11. The control panel 11 has a first indicator light 15 and a second indicator light 16. The first indicator light 15 is a temperature indicator light, used to check the heating status when the control board is connected by observing its on / off state and brightness. The temperature control knob 13 is used to adjust the heating range. The second indicator light 16 is a photon light, used to display the performance of the control board by observing its flashing and flashing frequency. The voltage display meter 14 displays the voltage of the control board. After the power is connected via the power switch 12, the display interface of the control board is opened by pressing the button 31 on the control board, and the voltage display meter 14 will display the voltage of the control board.

[0044] By pressing the remaining buttons 31, the circuits for different performance tests of the control board are connected. The first indicator light 15 and the second indicator light 16 will display different states. Thus, by adjusting the buttons 31 and the temperature control knob 13, different functions of the control board can be tested. The performance of the control board can be judged by the states of the first indicator light 15 and the second indicator light 16.

[0045] This embodiment is an embodiment of non-essential technical features. The specific detection circuit and function display may vary depending on the control board model and the circuit designed for different performance detection of the control board, and may be applied for in other applications.

[0046] It should be understood that the present invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of the invention is limited only by the appended claims.
