[0022] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-3 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0025] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0026] In one embodiment of this utility model, such as Figures 1-3 As shown, a circuit board pressure testing device for intelligent monitoring and testing of PoE switches is provided, including a frame 1, an elastic pressing mechanism 2, a folding mechanism 3, a vision module 4, and a fixing clamping device 5. The elastic pressing mechanism 2 is disposed above the frame 1 and is used to generate flexible elastic force to press the circuit board firmly onto the fixing clamping device 5. The folding mechanism 3 is disposed below the elastic pressing mechanism 2 and on the frame 1, and is used to bend one end of the circuit board. The vision module 4 is disposed on the frame 1 and is used to observe the state and changes of the circuit board during the bending process. The fixing clamping device 5 includes a linear movement mechanism, a mounting slide, and a clamping mechanism. The mounting slide is disposed at the moving end of the linear movement mechanism and moves to the bottom of the elastic pressing mechanism 2 under the drive of the linear movement mechanism. The clamping mechanism is disposed on the mounting slide and can clamp circuit boards of different shapes and sizes. The vision module 4 can be a CCD camera to record the process. The linear movement mechanism can adopt a linear module or other structure that enables linear movement of the mounting slide.
[0027] In use, the linear motion mechanism drives the clamping mechanism to engage the elastic pressing mechanism 2, facilitating the clamping of the circuit board. The circuit board is then placed in the clamping mechanism, which, due to its adjustability, can accommodate circuit boards of different shapes and sizes. After fixing the circuit board horizontally, the linear motion mechanism drives the clamping mechanism directly beneath the elastic pressing mechanism 2. The elastic pressing mechanism 2 presses down and secures the circuit board, providing a certain degree of elastic cushioning to prevent excessive pressure from causing hard impact damage. Then, the folding mechanism 3 folds the side of the circuit board, and the vision module 4 records the folding process. Thus, the adjustable clamping mechanism allows for the clamping of circuit boards of different shapes and sizes, offering better adaptability.
[0028] It also includes a data acquisition system, which is connected to vision module 4 and is used to record data during the circuit board bending process.
[0029] The data acquisition system includes pressure sensors and displacement sensors. The pressure sensors monitor the forces acting on the circuit board during the folding process, while the displacement sensors record the folding displacement of the circuit board. The data acquisition system transmits the data to a computer in real time for analysis and processing.
[0030] In this example, the clamping mechanism includes a base 10, a support assembly 20, a lateral stop 30, and a clamping assembly 40. The base 10 is mounted on a mounting slide. The support assembly 20 is mounted on the base 10 and supports the circuit board. The lateral stop 30 and the clamping assembly 40 are both mounted on the base 10 and arranged opposite to each other. The lateral stop 30 is used to laterally limit the movement of the circuit board. The clamping assembly 40 is used to laterally press the circuit board and, together with the lateral stop 30, fixes the circuit board. Specifically, the support assembly 20, the lateral stop 30, and the clamping assembly 40 are all mounted on the base 10. The support assembly 20 is positioned between the lateral stop 30 and the clamping assembly 40. The position of the clamping assembly 40 on the base 10 is adjustable to accommodate circuit boards of different sizes. The circuit board is fixed by the clamping assembly 40 and the lateral stop 30.
[0031] In this example, the clamping assembly 40 includes a sliding structure 41, a movable plate 42, an elastic buffer 43, and a locking structure 44. The sliding structure 41 is mounted on the base 10, and the movable plate 42 is slidably connected to the sliding structure 41. The elastic buffer 43 is mounted on the movable plate 42 and is used to laterally fix the circuit board to the lateral stop 30. The locking structure 44 is connected to the movable plate 42 and is used to fix the position of the movable plate 42 on the sliding structure 41. Specifically, the elastic buffer 43 can prevent excessive lateral pressure on the circuit board during clamping, thus avoiding damage to the circuit board, and the elastic buffer 43 presses the circuit board laterally against the lateral stop 30. After clamping, the locking structure 44 fixes the movable plate 42 in the position of the sliding structure 41, thereby ensuring the stability of the clamping.
[0032] In this example, the locking structure 44 includes a limiting member 441, a cam block 442, a positioning block 443, a guide rod 444, and a compression spring 445. The cam block 442 is disposed on the base 10 and can rotate horizontally on the base 10. The cam block 442 is provided with an arc-shaped sliding hole 446. The limiting member 441 is disposed on the base 10 and is limited within the arc-shaped sliding hole 446. The positioning block 443 is located between the lateral stop block 30 and the moving plate 42. One end of the guide rod 444 is fixedly connected to the positioning block 443, and the other end is slidably connected to the moving plate 42. The compression spring 445 is sleeved outside the guide rod 444, and one end of the compression spring 445 is connected to the positioning block 443, and the other end is connected to the moving plate 42. Specifically, it may also include a handle connected to the cam block 442. The handle controls the rotation of the cam block 442, and when the cam block 442 rotates, the limiting member 441 moves relative to the cam block 442 within the arc-shaped sliding hole 446. The limiting member 441 can be a positioning screw. The moving plate 42 has a through hole, and one end of the guide rod 444 extends into the through hole. Rotating the handle causes the cam block 442 to rotate, pushing the moving plate 42 closer to the circuit board. The moving plate 42 and the guide rod 444 are relatively displaced, and the compression spring 445 is compressed. The cam block 442 is connected to the base 10 by screws, thereby enabling the handle to be rotated. The internal thread of the cam block 442 engages with the external thread of the screw to achieve locking.
[0033] In this example, the sliding structure 41 includes a slide rail 211 and a slider 212. The slide rail 211 is vertically and laterally stopped by the block 30. The slider 212 is slidably connected to the slide rail 211, and the upper end of the slider 212 is fixedly connected to the moving plate 42 by a connector, which can be a screw. Specifically, the slide rail 211 and the slider 212 ensure the stable sliding of the moving plate 42.
[0034] In this example, the elastic buffer 43 is a spring plunger, which is respectively disposed at both ends of the movable plate 42, and the retractable end of the spring plunger is disposed towards the lateral stop 30.
[0035] In this example, the support assembly 20 includes several support platforms 21 and two lateral support blocks 22. Each support platform 21 is disposed between the lateral stop block 30 and the clamping assembly 40, and the two lateral support blocks 22 are disposed opposite each other on both sides of the lateral support blocks 22. Specifically, the support platforms 21 are used to support the circuit board, and the distance between the two lateral support blocks 22 is less than the length of the circuit board to avoid affecting the folding mechanism 3 in folding the circuit board.
[0036] In this example, the elastic pressing mechanism 2 includes an electric push rod 50, a connecting rod seat 60, a floating structure 70, and a roller 80. The electric push rod 50 is mounted on the frame 1, and the connecting rod seat 60 is connected to the output end of the electric push rod 50. The floating structure 70 is located at the end of the connecting rod seat 60 away from the electric push rod 50 and can float up and down under force. The roller 80 is connected to the floating structure 70. The floating structure 70 includes a tension spring 71 and a floating block 72. The floating block 72 is slidably connected to the connecting rod seat 60 and can move vertically relative to the connecting rod seat 60. One end of the tension spring 71 is connected to the floating block 72, and the other end is connected to the connecting rod seat 60. Both ends of the roller 80 are connected to the floating block 72.
[0037] In this example, the folding mechanism 3 includes a drive motor, a folding arm, and a pressure sensor. The drive motor is mounted on the frame 1, the folding arm is connected to the output of the drive motor, and the pressure sensor is mounted on the folding arm, specifically on the side of the folding arm that contacts the circuit board. Specifically, the folding arm is driven by a high-precision servo motor to achieve precise angle control. Simultaneously, the inner side of the folding arm is provided with a flexible material to prevent damage to the circuit board during the folding process. The driving method of the folding arm can be replaced; for example, a pneumatic or hydraulic drive can be used instead of the servo motor drive.
[0038] Furthermore, the folding mechanism 3 also includes an angle control mechanism, which includes an encoder and a controller. The encoder is used to monitor the folding angle of the folding arm in real time and transmit the data to the controller. The controller adjusts the rotation of the servo motor according to the data from the encoder, thereby achieving precise folding angle control.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
