[0002] As a core component of modern electronic devices, the quality of printed circuit boards (PCBs) directly affects device performance. With the miniaturization and increasing complexity of electronic products, the functional testing requirements for PCBs are becoming increasingly stringent.

[0003] However, traditional testing methods rely on manual testing or simple automated equipment, which are inefficient and prone to errors. Furthermore, the PCB board is inconvenient to remove after testing, making it difficult to meet the needs of efficient and accurate testing.

[0004] In conclusion, there is an urgent need for a functional testing fixture for PCB boards to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional testing methods, which rely on manual testing or simple automated equipment, resulting in low efficiency, easy errors, and inconvenience in removing the PCB board after testing, this utility model mainly provides a functional testing fixture for PCB boards.

[0006] A functional testing fixture for PCB boards includes an operating table as a mounting carrier for components; a worktable placed on the operating table; four mounting plates arranged in a rectangular shape and detachably mounted on the worktable; a fixing block connected to the mounting plates; a clamping plate slidably connected to the fixing block; an elastic element wound around adjacent clamping plates and fixing blocks; a mounting frame connected to the lower side of the worktable; a first cylinder mounted on the mounting frame; a top plate connected to the top end of the telescopic rod of the first cylinder, the top plate contacting the worktable; a fixing frame disposed on the worktable; a second cylinder mounted on the fixing frame; a detection plate connected to the piston of the second cylinder, the lower side of the detection plate having multiple probes; and a guide rod disposed on the fixing frame, the detection plate and the guide rod being slidably connected.

[0007] As a further preferred option, a protective plate is also included, which is detachably attached to the front side of the worktable.

[0008] As a further preferred embodiment, a protective pad is also included, attached to one side of the four clamps near the top plate.

[0009] As a further preferred embodiment, it also includes electric actuators, with four electric actuators arranged in a rectangular pattern and installed on the lower inner side of the operating table, the top of the upper actuator of each electric actuator being connected to the worktable.

[0010] As a further preferred embodiment, a first antistatic plate is also included, attached to the upper side of the top plate.

[0011] As a further preferred embodiment, a temperature sensor is also included, which is mounted on the worktable. The temperature sensor has a U-shaped structure, and the top plate is located within the inner circle of the temperature sensor.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0023] Example: A functional testing fixture for PCB boards, such as... Figures 1-4 As shown, the device includes an operating table 1, a workbench 3, a mounting plate 4, a fixing block 5, a clamping plate 6, an elastic element 7, a mounting frame 9, a first cylinder 10, and a top plate 11. The operating table 1 serves as the mounting carrier for the parts. The workbench 3 is placed on the operating table 1. Four mounting plates 4 are detachably mounted on the workbench 3, arranged in a rectangular pattern. Fixing blocks 5 are connected to the four mounting plates 4, and clamping plates 6 are slidably connected to the fixing blocks 5. Elastic elements 7 are wound around adjacent clamping plates 6 and fixing blocks 5. The mounting frame 9 is connected to the lower side of the workbench 3. The first cylinder 10 is mounted on the mounting frame 9. The top of the telescopic rod of the first cylinder 10 is connected to the top plate 11, which contacts the workbench 3. The fixing frame is set on the workbench. The second cylinder is mounted on the fixing frame. The detection plate is connected to the piston of the second cylinder. Multiple probes are provided on the lower side of the detection plate. A guide rod is set on the fixing frame, and the detection plate and the guide rod are slidably connected.

[0024] like Figure 3 As shown, it also includes a protective plate 2, which is detachably connected to the front side of the operating table 1.

[0025] like Figure 3 As shown, it also includes a protective pad 8, which is connected to one side of the four-ply plate 6 near the top plate 11.

[0026] like Figure 4 As shown, it also includes electric push rods 12. Four electric push rods 12 are installed on the lower inner side of the operating table 1. The four electric push rods 12 are arranged in a rectangular shape, and the top of the push rod of the electric push rod 12 is connected to the worktable 3.

[0027] like Figure 5 As shown, it also includes a first antistatic plate 13, which is connected to the upper side of the top plate 11.

[0028] like Figure 5 As shown, it also includes a temperature sensor 14. The temperature sensor 14 is installed on the worktable 3. The temperature sensor 14 has a U-shaped structure and the top plate 11 is located in the inner circle of the temperature sensor 14.

[0029] like Figure 2 As shown, it also includes a second antistatic plate 15. The second antistatic plate 15 is connected to the side of the workbench 3. A rectangular groove is opened on the second antistatic plate. The first antistatic plate 13 is located in the rectangular groove on the second antistatic plate 15.

[0030] like Figure 2 As shown, it also includes a pressure sensor 16, which is installed on the side of the clamp 6 near the second antistatic plate 15.

[0031] When this device is needed, first activate the electric push rod 12 to extend it and move the worktable 3 upward. As the worktable 3 moves, it also moves the mounting plate 4, fixing block 5, clamping plate 6, elastic element 7, protective pad 8, mounting bracket 9, first cylinder 10, top plate 11, electric push rod 12, first antistatic plate 13, temperature sensor 14, second antistatic plate 15, and pressure sensor 16 to different positions. Once the worktable 3 reaches the appropriate height, stop the electric push rod 12. This operation allows for adjusting the height of the worktable 3 according to the comfort level of different workers. Next, manually move the clamping plate 6. The elastic element 7 deforms adaptively, placing the PCB board on the second antistatic plate 15. Since the second antistatic plate 15 has antistatic properties, it facilitates subsequent testing. After releasing the clamping plate 6, the elastic element 7 returns to its original shape, and the clamping plate 6 resets under the elastic force of the elastic element 7, firmly clamping the PCB board. The protective pad 8 protects the PCB board from damage. The second cylinder lowers the detection plate, and the probe on the lower side of the detection plate contacts the PCB board to perform the detection operation. During this process, the pressure sensor 16 can detect the pressure applied to the PCB board by the clamping plate 6, while the temperature sensor 14 can monitor the temperature change of the PCB board in real time. After the detection operation is completed, the first cylinder 10 is activated, which extends its telescopic rod and moves the top plate 11 and the first antistatic plate 13 upward. The top plate 11 pushes out the PCB board, making it easy for the staff to remove the PCB board. Then, the elastic element 7 returns to its original state, and the clamping plate 6 and the protective pad 8 are reset under the elastic force of the elastic element 7. Finally, the electric push rod 12 is controlled to operate in reverse, driving the above components to complete the reset action. If the clamping plate 6 needs to be replaced, the mounting plate 4 is removed from the worktable 3, and another model of mounting plate 4 is replaced on the worktable 3, thereby realizing the quick replacement of different models of clamping plates 6.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
