[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 、 Figure 2 and Figure 3 The utility model provides an embodiment: a PCB crimping jig, including a base plate 1, the base plate 1 is the basic part of the entire crimping jig, and provides a stable installation platform for other components. A PCB board 4 is provided on the upper surface of the base plate 1. The PCB board 4 is the object that needs to be crimped and carries various electronic components and circuits. A rotating seat 1 5 and a rotating seat 2 6 are provided on one side of the upper surface of the base plate 1. The rotating seat 1 5 and the rotating seat 2 6 are used to install and support the crimping assembly to ensure the stability and flexibility of the crimping assembly during operation. The crimping assembly for crimping the PCB board 4 is installed inside the rotating seat 1 5 and the rotating seat 2 6.

[0024] The crimping assembly includes a connecting shaft 7, which is a key component connecting the rotating seat 1 5, the rotating seat 2 6 and the rotating frame 8. It enables the rotating frame 8 to rotate smoothly between the rotating seat 1 5 and the rotating seat 2 6, thereby realizing the crimping operation on the PCB board 4. Its outer wall is set inside the rotating seat 1 5 and the rotating seat 2 6. The outer wall of the connecting shaft 7 is fixedly connected to the rotating frame 8. The rotating frame 8 rotates under the drive of the connecting shaft 7, and the external force is transmitted to the pressure plate 10 to complete the crimping action. The interior thereof is penetrated by a mounting groove 9. The interior of the rotating frame 8 is fixedly connected to the pressure plate 10. The pressure plate 10 is in direct contact with the PCB board 4 and applies pressure. The pressure-applying part firmly connects the electronic component to the PCB board 4 through appropriate pressure. The outer wall of the connecting shaft 7 is installed with an auxiliary component for driving the rotating frame 8 to rotate; the auxiliary component includes a handle 13, which is the part where the operator applies external force, so that the operator can control the crimping process through manual operation. One side of the inner wall is rotatably connected to the outer wall side of the connecting shaft 7, and a wedge 12 is provided inside the bottom plate 1. The wedge 12 is used to interact with the handle 13 to limit the rotation range of the handle 13. The outer wall of the handle 13 contacts the upper surface of the wedge 12, so that the operator can control the force and depth of the crimping more accurately.

[0025] Reference Figure 1 、 Figure 2 and Figure 3 The symmetrical design of the mounting holes 2 can make the fixation more stable, and ensure that the jig will not shake during the crimping process, thereby ensuring the accuracy of the crimping. A limiting groove 11 is provided on one side of the interior of the base plate 1, and the lower surface of the wedge block 12 is attached to the inner wall of the limiting groove 11. The limiting groove 11 plays a role in positioning and limiting the moving direction of the wedge block 12, so that the wedge block 12 can only move in a specific direction, ensuring that the cooperation between the wedge block 12 and the handle 13 is stable and reliable, thereby accurately controlling the crimping force. The upper surface of the base plate 1 is fixedly connected with the symmetrical positioning posts 3 on the upper surface of the base plate 1, and the inner wall of the PCB board 4 is penetrated by the outer wall of the positioning posts 3. The positioning posts 3 can accurately determine the position of the PCB board 4 on the base plate 1, prevent the PCB board 4 from moving during the crimping process, and ensure that the pressing plate 10 can accurately apply pressure to the part of the PCB board 4 that needs to be crimped. The outer wall of the pressing plate 10 is slidably connected to the inner wall of the mounting groove 9. The mounting groove 9 is used to The pressing plate 10 provides an installation space. The installation groove 9 provides a stable installation position for the pressing plate 10 on the one hand, and allows the pressing plate 10 to slide within a certain range on the other hand to adapt to different crimping conditions, ensuring that the pressing plate 10 can smoothly apply pressure to the PCB board 4 during the crimping process. A slope is provided on the upper side of the wedge block 12, and the wedge block 12 is set in a trapezoidal shape. The slope is used to adjust the degree of downward pressure of the handle 13. When the operator presses down the handle 13, the handle 13 moves along the slope of the wedge block 12. The angle and length of the slope determine the distance and angle of the downward pressure of the handle 13, so that the crimping force can be accurately controlled to avoid damage to the PCB board 4 and components caused by excessive or insufficient pressure. The base plate 1 is made of pads, and the pad material has certain flexibility and stability. It can reduce the impact of vibration on the crimping process while bearing pressure, and the cost is relatively low. The rotating frame 8 is set in a left-right symmetrical manner. The left-right symmetrical rotating frame 8 can make the crimping process more balanced, ensuring that the pressure applied by the pressing plate 10 to the PCB board 4 is evenly distributed, thereby improving the crimping quality.

[0026] Working principle: When the jig needs to be used to crimp the PCB board 4, first install the base plate 1 on the fixed position platform through the mounting hole 2. Then, quickly position the PCB board 4 to be crimped through the positioning column 3 and place it. Then, turn the handle 13. The handle 13 drives the connecting shaft 7 to rotate inside the rotating seat 1 5 and the rotating seat 2 6. Then, the connecting shaft 7 is rotated to drive the pressure plate 10 inside the rotating frame 8 to be pressed on top of the PCB board 4. Then, turn the handle 13. At this time, the handle 13 is rotated parallel to the handle 13. The handle 13 moves on the inclined surface of the wedge block 12 to achieve the degree of crimping of the pressure plate 10 on the PCB board 4.
