[0051] Example 1

[0052] Please see Figure 1-5 Specifically, in this embodiment of the coupling base, the coupling base provided in this application is used to fix a PCB board 1. A tungsten copper plate 11 is installed on the bottom of the PCB board 1. The coupling base provided in this application specifically includes a base 2, a vacuum adsorption component 3, a limiting protrusion 4, a driving component 5, and a limiting component 6. The middle part of the base 2 is provided with a placement area for the PCB board 1. The vacuum adsorption component 3 is fixedly disposed in the placement area, and the vacuum adsorption component 3 adsorbs and fixes the tungsten copper plate 11 on the PCB board 1 placed in the placement area. The limiting protrusion 4 is fixedly disposed on the base 2, and the limiting protrusion 4 abuts against one side edge of the tungsten copper plate 11 on the PCB board 1 placed in the placement area. The driving component 5 is fixedly disposed on the base 2. The limiting component 6 is disposed on the base 2, and the limiting component 6 abuts against the other side edge of the tungsten copper plate 11 located in the placement area under the driving action of the driving component 5. The limiting component 6 and the limiting protrusion 4 are distributed on both sides of the placement area.

[0053] Specifically, this utility model provides a coupling base for fixing a PCB board 1. A tungsten copper plate 11 is mounted on the bottom of the PCB board 1. The coupling base provided in this application specifically includes a base 2, a vacuum adsorption component 3, a limiting protrusion 4, a driving component 5, and a limiting component 6. The middle part of the base 2 is provided with a placement area for the PCB board 1. The vacuum adsorption component 3 is fixedly disposed in the placement area and adsorbs and fixes the tungsten copper plate 11 on the PCB board 1 placed in the placement area. The limiting protrusion 4 is fixedly disposed on the base 2 and abuts against one side edge of the tungsten copper plate 11 on the PCB board 1 placed in the placement area. The driving component 5 is fixedly disposed on the base 2. The limiting component 6 is disposed on the base 2 and abuts against the other side edge of the tungsten copper plate 11 located in the placement area under the driving action of the driving component 5. The limiting component 6 and the limiting protrusion 4 are distributed on both sides of the placement area. This application achieves clamping and fixing of the tungsten copper plate 11 mounted on the bottom of the PCB board 1 by setting a limiting protrusion 4 and a limiting component 6, and driving the limiting component 6 through a driving component 5, thereby fixing the PCB board 1. By setting a vacuum adsorption component 3 in the placement area, the bottom of the tungsten copper plate 11 of the PCB board 1 is vacuum adsorbed by the vacuum adsorption component 3, preventing the PCB board 1 from tilting, thereby achieving a better horizontal fixing effect. The cylinder 51 drives the movement of the limiting component 6 to clamp the tungsten copper plate 11, so that the PCB board 1 is evenly stressed. Moreover, since this application limits the tungsten copper plate 11 at the bottom of the PCB board 1 through the limiting protrusion 4 and the limiting component 6, it can be applied to PCB boards 1 of different sizes. And since the PCB board 1 is made of plastic material, it can prevent the force from directly acting on the PCB board 1 and causing damage and deformation to the PCB board 1.

[0054] The vacuum adsorption component 3 can be implemented using an existing solenoid valve capable of vacuum adsorption. The installation and implementation principle of the solenoid valve will not be elaborated here, and it can be implemented using existing technology.

[0055] In one possible implementation, such as Figure 1-2 As shown, the number of limiting protrusions 4 can be set to two. The two limiting protrusions 4 are arranged at intervals on the base 2 to abut against the side edge of the tungsten copper plate 11 on the PCB board 1 and cooperate with the limiting component 6 to clamp the PCB board 1.

[0056] In one possible implementation, the coupling base further includes a pair of positioning pins 7, which are detachably mounted on the base 2. The positions of the positioning pins 7 correspond to the distribution positions of the two semi-circular positioning holes on the PCB board 1. The positions of the positioning pins 7 can be set according to the standard of the PCB board 1 to achieve coarse positioning of the PCB board 1.

[0057] In one possible implementation, the drive assembly 5 includes a cylinder 51 and an L-shaped connecting block 52. One end of the L-shaped connecting block 52 is fixedly connected to the base 2, and the other end of the L-shaped connecting block 52 is fixedly connected to the fixed end of the cylinder 51. The output rod of the cylinder 51 drives the limiting assembly 6 to move in a direction close to the placement area.

[0058] Specifically, by setting an L-shaped connecting block 52, the connection between the cylinder 51 and the base 2 is fixed, thereby fixing the position of the cylinder 51.

[0059] It should be noted that the output rod of cylinder 51 and the limiting component 6 are independent of each other. The output rod only moves when it is driven to abut against the limiting component 6, thereby pushing the abutment block 62 of the limiting component 6 closer to the placement area.

[0060] In one possible implementation, the coupling base also includes an adapter 8, which is detachably connected to the output rod of the cylinder 51.

[0061] Specifically, an adapter 8 is detachably installed at the end of the output rod of cylinder 51. The adapter 8 has a through hole, and two threaded holes communicating with the through hole can be installed through the side wall of the adapter 8. The output rod of cylinder 51 is inserted into the through hole of the adapter 8, and then a screw is inserted into the threaded hole to fix the adapter 8 against the side wall of the output rod. By setting the adapter 8, the error of the driving distance of cylinder 51 can be effectively compensated, and the accuracy of the driving displacement can be improved.

[0062] In one possible implementation, the limiting component 6 includes a limiting block 61, an abutment block 62, and a pair of springs 63. The limiting block 61 is fixed to the base 2 and protrudes from the top surface of the base 2. The portion of the limiting block 61 protruding from the top surface of the base 2 is provided with a through groove. One end of the abutment block 62 passes through the through groove and extends out of the through groove. The other end of the abutment block 62 is fixedly connected to the limiting block 61 with a pair of springs 63. Both springs 63 are in a compressed state. The driving component 5 drives the abutment block 62 to move in the direction close to the placement area.

[0063] Among them, a pair of springs 63 are symmetrically distributed on both sides of the through groove.

[0064] Furthermore, such as Figure 3As shown, the abutting block 62 includes an abutting part 621, a connecting part 622, a first limiting part 623, and a second limiting part 624. The abutting part 621 and the connecting part 622 have a cuboid structure. One end of the connecting part 622 is fixedly connected to the abutting part 621. The connecting part 622 is movably inserted into the through groove and is adapted to the size of the through groove. The first limiting part 623 is fixedly connected to the connecting part 622. The second limiting part 624 is fixedly provided on the end face of the other end of the connecting part 622. The second limiting part 624 abuts against the other side edge of the tungsten copper plate 11 located in the placement area.

[0065] Specifically, by configuring the abutment block 62 to include an abutment portion 621, a connecting portion 622, a first limiting portion 623, and a second limiting portion 624, and by connecting the two ends of the connecting portion 622 to the abutment portion 621 and the first limiting portion 623, the connecting portion 622 in the through groove is limited by the abutment portion 621 and the first limiting portion 623, so that the connecting portion 622 can only slide in the through groove of the limiting block 61 and will not slide out. The second limiting portion 624 is provided at the end of the connecting portion 622. The height of the second limiting portion 624 is less than the distance between the tungsten copper plate 11 and the substrate of the PCB board 1, so that the tungsten copper plate 11 is abutted by the second limiting portion 624 without contacting the PCB board 1. Figure 1 and Figure 2 This is a schematic diagram of the coupling base without the PCB board 1 placed on it. In this case, since there is a gap between the cylinder 51 and the contact part 621, and the spring 63 is compressed, when the cylinder 51 is not against the contact part 621, under the elastic force of the spring 63, one end of the connecting part 622 with the first limiting part 623 abuts against the limiting block 61. The placement area of ​​the coupling base is open, facilitating the placement of the PCB board 1. After the tungsten copper plate 11 is placed face down on the PCB board 1, the vacuum adsorption component 3 can perform vacuum adsorption on the tungsten copper plate 11. Then, the cylinder 51 is driven to push the contact block 62 to move and abut against the side edge of the tungsten copper plate 11, thereby achieving the limiting of the PCB board 1. Figure 5 This is a schematic diagram of PCB board 1 being clamped onto the coupling base.
