There is no need for personnel to adjust the positions of the two placement seats 9 during the process of placing the circuit board, and the operation is more convenient. The two ends of the synchronous slide bar 6 are respectively movably passed through the two placement seats 9, and the two ends of the synchronous slide bar 6 are fixedly provided with a limit head 6 1, used to prevent the synchronous slide bar 6 from slipping and separating from the placement seat 9, a connecting slide column 41 is fixedly connected at the central position of the bottom of the movable beam 4, the lower end of the connecting slide column 41 extends to the inside of the base 1, and a through groove 5 is opened on the top of the base 1 along the front-to-back direction, and the lower end of the connecting slide column 41 passes through the through groove 5, and a movable seat 12 is movably arranged inside the base 1, and connecting slide grooves 121 are symmetrically opened on the movable seat 12. The two connecting slide grooves 121 at the top of the movable seat 12 are opened in an eight-shaped shape, and the connecting slide column 41 slides along the connecting slide groove 121. By driving the movable seat 12 to move to the right, the two connecting slide columns 41 can be driven to move together with the movable beam 4, so that it can be suitable for clamping circuit boards of different specifications and sizes. The inside of the base 1 is rotatably connected with a screw rod 13 through a bearing, one end of the screw rod 13 is fixedly connected to the rotating end of a servo motor 11 fixedly installed on one side of the base 1, and the other end of the screw rod 13 is threadedly penetrated through a movable seat 12, a control switch 10 is fixedly installed on the front side of the base 1, and the control switch 10 is electrically connected to an external power supply through a wire, a top seat 3 is fixedly connected to the top of the base 1 through a support column 2, and a patch head 7 is fixedly installed at the center position of the bottom of the top seat 3, and the patch head 7 and the servo motor 11 are electrically connected to the control switch 10 through wires respectively. When patching the circuit board, the servo motor 11 can be driven to rotate by the control switch 10, and the rotation of the servo motor 11 can drive the screw 13 Rotate, the rotation of the screw 13 can drive the movable seat 12 to move to the right, and at this time the connecting slide 41 slides along the connecting slide groove 121, which can drive the two movable beams 4 to approach synchronously, and the two movable beams 4 approaching synchronously can drive the two placement seats 9 to approach synchronously, at this time the circuit board can be placed between the two placement seats 9, and the two placement seats 9 are driven to approach, and the circuit board is clamped and fixed. During this process, the synchronous slide bar 6 can make the two placement seats 9 move synchronously along the movable beam 4, and there is no need for personnel to adjust them to align in the front and rear directions.

[0023] Embodiment 2: The difference between this embodiment and embodiment 1 lies in that a pressure sensor 14 is fixedly connected to the inner wall of the placement seat 9. The provision of the pressure sensor 14 can prevent the circuit board from being subjected to excessive pressure, thereby causing damage to the circuit board. The pressure sensor 14 is electrically connected to the control switch 10 through a wire. In the process of placing and clamping the circuit board, as the two placement seats 9 approach synchronously, the pressure sensor 14 can feed back the pressure exerted on the circuit board to the control switch 10. When the pressure value reaches the set value, the control switch 10 can stop the rotation of the servo motor 11, so that the two placement seats 9 no longer continue to approach each other, thereby preventing the circuit board from being subjected to excessive pressure and being damaged.

[0024] Working principle: When using, when mounting a circuit board, the servo motor 11 can be driven to rotate by the control switch 10. The rotation of the servo motor 11 can drive the screw 13 to rotate. The rotation of the screw 13 can drive the movable seat 12 to move to the right.

The synchronous approach of the two movable beams 4 can drive the two placement seats 9 to approach synchronously. At this time, the circuit board can be placed between the two placement seats 9, and the two placement seats 9 are driven to approach to each other to clamp and fix the circuit board. In this process, the synchronous slide bar 6 can make the two placement seats 9 synchronously It moves along the movable beam 4 without the need for personnel to adjust it to the front-to-back direction alignment, and then the placement seat 9 can be driven to move by manually toggling the synchronous slide bar 6, and the circuit board can be moved to just below the placement machine head 7, and the circuit board can be mounted through the placement machine head 7. In the process of placing and clamping the circuit board, as the two placement seats 9 approach synchronously, the pressure sensor 14 can feedback the pressure on the circuit board to the control switch 10. When the pressure value reaches the set value, the control switch 10 can stop the servo motor 11 from rotating, so that the two placement seats 9 will no longer continue to approach, thereby preventing the circuit board from being damaged by excessive pressure.
