The following description is based on the accompanying drawings. Figures 1-5 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0026] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. 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.

[0028] 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.

[0029] In one embodiment of this utility model, such as Figures 1-5 As shown, a circuit board compression testing device is provided, including a frame 10, a fixing fixture 20, a stamping mechanism 30 and a display module 40; the display module 40 is disposed at the bottom of the frame 10. The fixing fixture 20 and the stamping mechanism 30 are respectively arranged opposite to each other above and below the frame 10, that is, the stamping mechanism 30 is located directly above the fixing fixture 20; the display module 40 is connected to the stamping mechanism 30 and is used to display the data transmitted by the stamping mechanism 30; the fixing fixture 20 includes a fixing base 21, a fixing frame 22, a first clamping mechanism 23, a second clamping mechanism 24 and a driving mechanism 25; the fixing frame 22 is arranged on the frame 10, the fixing base 21 is arranged on the top of the fixing frame 22 and is used to place the circuit board, the driving mechanism 25 is arranged at the bottom of the fixing frame 22, the first clamping mechanism 23 and the second clamping mechanism 24 are arranged opposite to each other on both sides of the fixing base 21 and are both connected to the output end of the driving mechanism 25. Under the drive of the driving mechanism 25, the first clamping mechanism 23 and the second clamping mechanism 24 fix the circuit board on the fixing base 21, wherein the first clamping mechanism 23 is used to fix the circuit board in the horizontal direction of the fixing base 21, and the second clamping mechanism 24 is used to fix the circuit board in the vertical direction of the fixing base 21.

[0030] In use, the circuit board is placed on the fixing base 21, and then the drive mechanism 25 drives the first clamping mechanism 23 and the second clamping mechanism 24 to clamp and fix the circuit board, so that the circuit board is fixed in both the horizontal and vertical directions. Then, the stamping mechanism 30 stamps the circuit board, and the display module 40 displays the data fed back by the stamping mechanism 30. In this way, the circuit board compression testing equipment not only improves the accuracy and reliability of the test, but also reduces the complexity and cost of operation, providing a more efficient and safer solution for testing the compression performance of circuit boards.

[0031] Furthermore, a protective cover can be installed outside the circuit board pressure testing equipment, with an observation window to prevent personnel injury from flying broken parts during the test, thus improving safety.

[0032] In this example, the first clamping mechanism 23 includes a first mounting base 231, an L-shaped plate 232, and a first pressure block 233. The first mounting base 231 is connected to the fixing frame 22. The middle part of the L-shaped plate 232 is rotatably connected to the first mounting base 231, and one end of the L-shaped plate 232 is rotatably connected to the driving mechanism 25, while the other end is provided with the first pressure block 233. When clamping the circuit board, the first pressure block 233 contacts the side end of the circuit board. Specifically, since the middle part of the L-shaped plate 232 is rotatably connected to the first mounting base 231, and one end of the L-shaped plate 232 is rotatably connected to the driving mechanism 25, when the driving mechanism 25 drives it to move upward, the L-shaped plate 232 rotates, and the end of the L-shaped plate 232 with the first pressure block 233 moves outward away from the circuit board, thereby releasing the lateral fixation of the circuit board.

[0033] Furthermore, the portion of the first pressure block 233 that contacts the circuit board is made of a soft material, such as silicone or rubber, to reduce damage to the circuit board while providing sufficient friction to prevent the circuit board from moving during testing.

[0034] In this example, the second clamping mechanism 24 includes a second mounting base 241, a rotating arm 242, a guide rod 243, and a second pressure block 244. The second mounting base 241 is connected to the drive mechanism 30. The rotating arm 242 has a sliding hole 245 extending along its length in the middle, and one end of the rotating arm 242 is rotatably connected to the second mounting base 241, while the other end is provided with the second pressure block 244. When clamping the circuit board, the second pressure block 244 contacts the upper surface of the circuit board. One end of the guide rod 243 is connected to the fixing frame 22, and the other end is confined within the sliding hole 245. Specifically, when the drive mechanism 25 drives the rotating arm 242 to move upward, the rotating arm 242 rotates, and the end of the rotating arm 242 with the second pressure block 244 moves outward away from the circuit board, thereby releasing the lateral fixation of the circuit board. The guide rod 243 can limit the rotation amplitude and direction of the rotating arm 242.

[0035] The part of the second pressure block 244 that contacts the circuit board is made of a soft material, such as silicone or rubber, to reduce damage to the circuit board while providing sufficient friction to prevent the circuit board from moving during testing.

[0036] In this example, the mounting base 21 includes a mounting plate 211, an adjusting block 212, two lateral positioning blocks 213, and several support platforms 214. The mounting plate 211 is fixed to the top of the mounting frame 22. The two lateral positioning blocks 213 are disposed opposite each other on both sides of the mounting plate 211, forming a placement groove 215 for placing the circuit board. The adjusting block 212 is disposed on the side of the mounting plate 211 near the second clamping mechanism 24. The support platforms 214 are disposed on the mounting plate 211 and located within the placement groove 215. Specifically, the adjusting block 212 is disposed on the mounting frame 22, and its position can be adjusted according to requirements to accommodate circuit boards of various specifications. The adjusting block 212 is disposed opposite to the first pressure block 233, so that during the fixing process, the adjusting block 212, the first pressure block 233, and the two lateral positioning blocks 213 laterally fix the sides of the circuit board.

[0037] In this example, each support platform 214 is made of rubber, and each support platform 214 has multiple frustum-shaped protrusions on its end face. Specifically, the part of the fixture that contacts the circuit board uses a soft material, such as silicone or rubber, to reduce damage to the circuit board. Simultaneously, the multiple frustum-shaped protrusions on the end face of each support platform 214 provide sufficient friction to prevent the circuit board from moving during testing. Each support platform 214 suspends the circuit board, ensuring normal stamping.

[0038] In this example, a buffer mechanism 50 is also included. The buffer mechanism 50 includes a guide rod, a first spring, and a second spring. The bottom of the fixed base 21 is provided with a mounting hole for receiving the guide rod. The guide rod is vertically disposed at the bottom of the fixed base 21, and one end of the guide rod extends out of the fixed base 21. The first spring is sleeved on the guide rod. The second spring is disposed on the first clamping mechanism 23 and is disposed opposite to the first spring. Specifically, the buffer mechanism 50 provides elastic buffering force, which can prevent over-clamping and protect the circuit board.

[0039] In this example, the mounting bracket 22 includes a first side plate 221, a second side plate 222, a connecting plate 223, and a base plate 224. The first side plate 221 and the second side plate 222 are disposed opposite each other on both sides of the connecting plate 223, and the first side plate 221, the second side plate 222, and the connecting plate 223 are all connected to the base plate 224. A first clamping mechanism 23 is disposed on the first side plate 221, and a fixing seat 21 is disposed on the connecting plate 223. Specifically, the first side plate 221, the second side plate 222, the connecting plate 223, and the base plate 224 can improve the overall structural strength of the mounting bracket 22 and provide an installation environment for each component.

[0040] In this example, the drive mechanism 25 includes a power element 251 and a drive base 252. The power element 251 is mounted on the bottom of the fixed frame 22, and the drive base 252 is connected to the telescopic end of the power element 251. One end of the first clamping mechanism 23 and one end of the second clamping mechanism 24 are both rotatably connected to the drive base 252. Specifically, the power element 251 can be an electric cylinder, hydraulic cylinder, etc. One end of the L-shaped plate 232 is rotatably connected to the drive base 252, and one end of the rotating arm 242 is rotatably connected to the drive base 252, thereby simultaneously driving the first clamping mechanism 23 and the second clamping mechanism 24 to rotate via the drive base 252.

[0041] In this example, the stamping mechanism 30 includes a stamping power component, a stamping rod, a pressure sensor, and a stamping head. The stamping rod is connected to the bottom of the stamping power component, and a pressure sensor is installed at the bottom of the stamping rod. The stamping head is installed at the bottom of the pressure sensor. Specifically, the stamping power component (which can be an electric cylinder, hydraulic cylinder, etc.) is controlled to move downwards and its power is continuously increased. By observing whether the surface of the circuit board breaks, the pressure value of the pressure sensor is recorded at the moment of breakage, which is the pressure value of the frontal pressure resistance. The pressure value of the pressure sensor is displayed through the display module 40.

[0042] In this example, a vision module is also included, mounted on the mounting bracket 22, and used to capture images of the circuit board being stamped. Specifically, the equipment is equipped with a real-time monitoring system (vision module, such as a CCD camera), which can monitor the status of the circuit board in real time during the test. If an anomaly is detected, the test will be stopped immediately and an alarm will be issued to ensure the safety and accuracy of the test.

[0043] 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.
