Description

Technical Field

[0001] This utility model relates to a PCB circuit board testing machine, belonging to the field of PCB circuit board production technology. Background Technology

[0002] As an important electronic component, the PCB circuit board is the support for electronic components and the carrier for electrical connections between them. Its quality directly affects the quality of electronic components. Therefore, PCB testing is particularly important. During the mass production process, PCBs need to be tested by testing machines.

[0003] For example, a PCB circuit board testing machine with patent number CN202221809291.5 includes a machine body, with an infeed plate and an outlet plate respectively installed at the middle positions of both ends of the machine body. A support frame is installed on the top of the infeed plate and the outlet plate respectively. An adjustment mechanism is installed on the top of the support frame. The adjustment mechanism includes a lead screw, a slide rod and a fixing sleeve. A fixing sleeve is installed between the lead screw and the slide rod, and the fixing sleeve is threadedly connected to the lead screw.

[0004] The aforementioned PCB circuit board testing machine guides the PCB circuit board to move through an internal drive structure. However, since the PCB circuit board needs to be tested from both sides during the testing process, the testing effect of a PCB circuit board from only one side is limited. Furthermore, the PCB circuit board needs to be removed and placed on its reverse side for retesting, which indirectly reduces the testing efficiency of the PCB circuit board and has certain adverse effects on actual use. Therefore, improvements are needed. Utility Model Content

It can also guide the movement of the PCB circuit board through a driving device and perform double-sided testing by flipping the PCB circuit board. This solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A PCB circuit board testing machine includes a circuit board testing machine body. A clamping main frame is fixedly connected to the left side of the circuit board testing machine body.

[0026] Please refer to Example 1 Figures 1-6 This utility model provides a technical solution:

[0027] A PCB circuit board testing machine includes a circuit board testing machine body 1. A clamping main frame 2 is fixedly connected to the left side of the circuit board testing machine body 1. An adjustment frame 3 is fixedly connected to the side of the inner wall of the clamping main frame 2. A servo motor 4 is fixedly installed on the inner wall of the adjustment frame 3. A threaded rod 5 is fixedly installed at the output end of the servo motor 4. A threaded sleeve plate 6 is threadedly connected to the surface of the threaded rod 5. A limit component is connected to the surface of the threaded sleeve plate 6. A stabilizing frame 7 is snapped onto one side of the threaded sleeve plate 6. A flip clamping frame 8 is rotatably connected to the inside of the stabilizing frame 7 through a pivot pin. A drive motor 9 with a bracket is fixedly installed on the side of the stabilizing frame 7. The output end of the drive motor 9 is fixedly installed to the pivot pin on the flip clamping frame 8.

[0028] Specifically, such as Figures 1-6 As shown, the limiting assembly includes a limiting slide plate 10 and a limiting groove 11. The limiting slide plate 10 is fixedly connected to the surface of the threaded sleeve plate 6, and the limiting groove 11 is formed on the surface of the inner wall of the adjusting frame 3. The inner wall of the limiting groove 11 and the surface of the limiting slide plate 10 are slidably connected. By setting the limiting slide plate 10 and the limiting groove 11, the movement trajectory of the threaded sleeve plate 6 is limited, so that the rotation of the threaded rod 5 can drive the threaded sleeve plate 6 to move.

[0029] Specifically, such as Figures 1-6As shown, there are two adjustment frames 3, which are connected vertically within the circuit board testing machine body 1. There are also two threaded sleeves 6 within each adjustment frame 3, which are connected horizontally within the adjustment frame 3. The multiple threaded sleeves 6 and adjustment frames 3 enhance the stability of the connection stabilizer 7. A tension protective cloth 12 is fixedly connected between the surface of the threaded sleeve 6 and the inner wall of the adjustment frame 3. The surface of the tension protective cloth 12 completely covers the front opening of the adjustment frame 3, providing dust protection for the internal structure of the adjustment frame 3.

[0030] Please refer to Example 2 Figures 1-6 The difference between this embodiment and Embodiment 1 is that: a fixed clamping side frame 13 is fixedly installed on the top of the flip clamping frame 8, an electric cylinder 14 is fixedly installed on the front side of the flip clamping frame 8, and a movable clamping side frame 15 is fixedly installed at the output end of the electric cylinder 14. A guide slide plate 16 is fixedly connected to the bottom of the movable clamping side frame 15, and a guide groove 17 is provided on the top of the flip clamping frame 8. The inner wall of the guide groove 17 is slidably connected to the surface of the guide slide plate 16. Both the main body of the fixed clamping side frame 13 and the main body of the movable clamping side frame 15 are U-shaped frames. A second drive motor 18 is fixedly mounted on the surface of the U-shaped frame via a bracket. A swing reversing plate 19 is fixedly mounted on the output end of the second drive motor 18. A clamping frame 20 is magnetically attached to the surface of the swing reversing plate 19. An electric cylinder 21 is fixedly mounted on the top of the clamping frame 20. A movable clamping plate 22 is fixedly mounted on the output end of the electric cylinder 21. A fixed clamping plate 23 is fixedly connected to the bottom of the inner wall of the clamping frame 20. The electric cylinder 21 is controlled to move... The guided movement of the movable clamping plate 22 causes it to move closer to the fixed clamping plate 23, clamping and constraining the edge of the PCB circuit board. Depending on the size of the PCB circuit board, the magnetic positioning constraint of the clamping frame 20 can be performed at different positions. As needed, the operation drive motor 2 18 drives the swing reversing plate 19 to rotate, which can complete the swing reversing operation of the two clamping frames 20. In conjunction with the operation of the electric cylinder 1 14, the movable clamping side frame 15 is moved, which can complete the adjustment and clamping of PCB circuit boards of different sizes in the same batch.

[0031] The working principle of this utility model is as follows: During use, the PCB testing machine body 1 can perform clamping and testing of PCB circuit boards. The PCB circuit board is placed in the clamping main frame 2 at the PCB testing machine body 1, that is, the PCB circuit board is clamped between the fixed clamping side frame 13 and the movable clamping side frame 15 in the flip clamping frame 8. The electric cylinder 21 can be controlled to guide the movement of the movable clamping plate 22, causing the movable clamping plate 22 to move closer to the fixed clamping plate 23, clamping and constraining the edge of the PCB circuit board. Depending on the size of the PCB circuit board, magnetic positioning and constraint of the clamping frame 20 can be applied at different positions. The drive motor 18 drives the swing reversing plate 19 as needed. The rotation allows for the swinging and reversing of the two clamping frames 20, and, in conjunction with the operation of the electric cylinder 14, it drives the moving clamping side frame 15 to move, enabling the adjustment and clamping of PCB circuit boards of different sizes and batches. As needed, the servo motor 4 can drive the threaded rod 5 to rotate. Through the setting of the limiting slide plate 10 and the limiting slide groove 11, the movement trajectory of the threaded sleeve plate 6 is limited, so that the rotation of the threaded rod 5 can drive the threaded sleeve plate 6 to move, thereby pulling the stabilizing frame 7 and the flip clamping frame 8 to move. Subsequently, the drive motor 9 can drive the flip clamping frame 8 to rotate, which facilitates the inspection of the front and back of the PCB circuit board, thereby achieving the detection operation effect of the PCB circuit board inspection probe.
