[0041] The present invention will now be described in further detail with reference to the accompanying drawings.

[0042] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0043] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0044] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0045] Please see Figure 1 - Figure 7 A circuit board testing device includes a support frame 1 and a support frame 1 rotatably connected to a support frame 3 via a rotating rod 2. It also includes a frame 4 slidably connected to the support frame 3, with a circuit board placed on the support frame 3. A positioning frame 5 is fixed on the support frame 3, and a positioning unit 6 cooperating with the support frame 3 is provided on the frame 4 for clamping and positioning the circuit board. An adjustment component 7 is provided on the support frame 1 and cooperating with the support frame 3 for adjusting the rotation angle of the support frame 3.

[0046] It should be noted that the circuit board is tested using an online testing instrument, which is an existing product. The online testing instrument tests the components on the circuit board one by one by applying test signals and operating power to the circuit board, and equates different circuit boards to different combinations of standard electronic components. This testing method can avoid circuit principle analysis and directly locate the faults in integrated ICs, discrete components or circuit nodes, so as to achieve accurate testing of the circuit board. This is a conventional setup in this field, so it will not be described in detail here.

[0047] It should also be noted that by placing the circuit board on the support frame 3, the positioning unit 6 squeezes the circuit board, thereby positioning the circuit board under pressure. The online testing instrument then performs testing on the circuit board, and the adjustment component 7 adjusts the angle and position of the circuit board according to actual needs, making it suitable for multi-angle testing requirements.

[0048] Furthermore, such as Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, it is worth noting that the positioning unit 6 includes a through groove 61 on the frame 4, in which a positioning rod 62 is slidably connected. A sliding groove 9 is provided on the frame 4, and the positioning rod 62 is slidably connected to the sliding groove 9. The sliding of the positioning rod 62 within the sliding groove 9 not only guides the positioning rod 62 but also effectively improves its stability when moving under force. The length of the sliding groove 9 is the same as the length of the through groove 61. A rotating shaft 63 is rotatably connected to the frame 4, and a servo motor a64 fixed to the rotating shaft 63 is fixed to the frame 4. A spur gear a65 is fixed to the rotating shaft 63, and two staggered toothed plates 66 are slidably connected to the frame 4. Plate 66 is fixed to positioning rod 62 by mounting ring 67 and screw rod 68 rotatably connected to bearing frame 3. Frame 4 is fixed with threaded sleeve 69 threaded to screw rod 68, and threaded sleeve 69 is slidably connected to bearing frame 3. Frame 4 is fixed with guide sleeve 13 slidably connected to bearing frame 3, and bearing frame 3 is fixed with guide rod 14. Guide sleeve 13 and guide rod 14 are slidably connected and slidably connected, and guide sleeve 13 is slidably sleeved on guide rod 14 to guide frame 4, further enhancing the stability of frame 4 when moving. Bearing frame 3 is fixed with bracket 610, and bracket 610 is fixed with drive motor 611. The output shaft of drive motor 611 is coaxially fixed with screw rod 68.

[0049] The limit plate 12 is fixed on the toothed plate 66, and the length of the limit plate 12 is greater than the length of the tooth of the toothed plate 66. The limit plate 12 can limit the movement of the toothed plate 66, so that the toothed plate 66 is not separated from the straight gear a65.

[0050] It should be noted that the positioning unit 6 can effectively position the circuit board, ensure that the circuit board maintains a stable angle positioning state during detection, and is suitable for circuit boards of various specifications and sizes. Moreover, the positioning unit 6 can significantly reduce the loosening and displacement problems that may occur during circuit board detection, thereby improving the accuracy and reliability of detection.

[0051] Further, according to Figure 2 and Figure 5 It should be noted that the positioning rod 62 is provided with a pressing assembly 8 for pressing the circuit board, and the pressing assembly 8 includes a groove 81 formed in the positioning rod 62, and a channel 82 formed in the positioning rod 62 and communicating with the groove 81. The transmission ring 83 is slidably connected to the channel 82, and the electric push rod 84 is fixed to the positioning rod 62. The hole 85 is formed in the positioning rod 62 and allows the electric push rod 84 to pass through. The output end of the electric push rod 84 is fixed to the transmission ring 83, and the positioning pressing plate 86 is fixed to the transmission ring 83. The rubber pad 11 is fixed to the positioning pressing plate 86. The rubber pad 11 is provided on the side wall of the bearing frame 3 and is provided as an inverted chamfered surface. The positioning pressing plate 86 is slidably connected to the groove 81.

[0052] It should be noted that the electric push rod 84 applies pressure to the transmission ring 83, which allows the transmission ring 83 to move within the defined channel 82. With the movement of the transmission ring 83, the positioning pressing plate 86 moves synchronously. The positioning pressing plate 86 applies pressure to the circuit board, and the electric push rod 84 serves as a power source to effectively control the pressure applied to the circuit board. In this way, the circuit board is pressed and positioned. This pressing and positioning method can adapt to circuit boards of different thickness specifications and meet various pressing and positioning work requirements. The structure is simple but has high reliability, so it has strong applicability in practical applications. Embodiment

[0054] It should be noted that, through the setting of the adjusting assembly 7, the angle position between the bearing frame 3 and the circuit board and the support frame 1 can be effectively adjusted, and the detection work of the circuit board at various angles can be realized, thereby greatly expanding the application range of the circuit board detection work. This adjusting mechanism effectively prevents the detection work from being hindered due to inflexible or inconvenient angle adjustment, ensuring smooth and efficient detection process.
