DETAILED DESCRIPTION

[0021] The utility model will be explained further in detail now in combination with the drawings. The drawings are simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the components related to the utility model.

[0022] Please refer to Figures 1-4 A kind of SMT printing mounting support seat, including support seat body 1 and the circuit board 2 placed in support seat body 1, the surface of the support seat body 1 is equipped with recess 11, the circuit board 2 is equipped in recess 11, the surface of the recess 11 is equipped with the through reserved slot 12, the surface of the recess 11 is equipped with multiple positioning column 13 limiting the circuit board 2, the lower of the support seat body 1 is also equipped with the blowing suction auxiliary device facilitating circuit board limiting removal.

[0023] In use, the circuit board to be printed is placed in the recess 11 of the support seat body 1, and after being placed, the circuit board is limited by the positioning column 13 to avoid deviation and shaking of the circuit board during printing;The reserved slot 12 is provided for the electronic components on the circuit board, including resistors, diodes, chips, integrated blocks, etc., and after being placed, the electronic components fall into the corresponding reserved slot 12, so that the surface of the circuit board 2 is flat, which is conducive to improving the printing quality.

[0024] In the embodiment, after the circuit board 2 is placed in the recess 11, the surface of the circuit board 2 is 0.5mm higher than the support seat body, which is more conducive to printing after being higher.

[0025] Further, the inner wall of the recess 11 is provided with a plurality of arc-shaped recesses 14, and the outer wall of the circuit board 2 is provided with an arc-shaped protrusion 22 matched with the arc-shaped recesses 14, the arc-shaped protrusion 22 cooperates with the arc-shaped recesses 14 after the circuit board 2 is placed in the recess 11, and the cooperation of the arc-shaped protrusion 22 and the arc-shaped recesses 14 can further improve the limiting and avoid the shaking and deviation of the circuit board.

[0026] Among them, the arc-shaped recesses 14 are provided with three, the positioning column 13 is four, the circuit board 2 is provided with a positioning hole 21 matched with the positioning column 13, and the other is provided on the surface of the recess.

[0027] In this embodiment, the suction and blowing auxiliary device includes multiple suction nozzles 3. The suction nozzles 3 are funnel-shaped and disposed in the recess 11. Each suction nozzle 3 has a through hole 31. The bottom surface of the support body 1 is provided with a branch pipe 4 connected to the suction nozzles 3 on the same side. A branch pipe 5 is connected to the middle of the branch pipe 4. The branch pipe 4 and the branch pipe 5 are connected in a T-shape. Both ends of the branch pipe 4 are sealed and cover the through hole 31 in the suction nozzle 3. Both the branch pipe 4 and the branch pipe 5 are fixed to the bottom surface of the support body 1 by pipe clamps 6.

[0028] like Figure 4 As shown, during the printing process of circuit board 2, branch pipe 2 5 is connected to an external suction and blow air pump or a vortex air pump. At this time, the air in the suction nozzle 3 will be drawn outward. When circuit board 2 is placed in the recessed platform 11, circuit board 2 covers the suction nozzle 3. Therefore, when the air is drawn out, circuit board 2 is closer to the bottom surface of the recessed platform, increasing the tightness and preventing circuit board 2 from sticking during printing. Similarly, after the printing work is completed, the pump blows air. The blown air enters the corresponding suction nozzle 3 through branch pipe 2 5 and branch pipe 1 4. At this time, the circuit board 2 above will be blown, making the circuit board loose and easy to remove. Therefore, the suction and blow auxiliary device can not only improve the stability of the circuit board during printing, but also blow the circuit board after printing for easy removal, which is highly practical.

[0029] As a second embodiment of this application, please refer to Figure 5 In this embodiment, each of the suction nozzles 3 corresponds to an L-shaped connecting pipe 7. One end of the connecting pipe 7 seals and covers the through hole 31 inside the suction nozzle, and the other end extends outward to connect with a suction and blowing air pump or a vortex air pump, which can greatly improve the suction and blowing force of air and further improve the use effect.

[0030] Based on the above embodiments, the support base body 1 is also provided with support pads 15 at the four corners of the bottom surface, wherein the height of the support pads 15 is greater than the outer diameter of the suction pipe, so as to ensure that the support base body 1 is stably supported by the support pads 15.

[0031] Based on the above embodiments, the size of the recess 11 is molded according to the size of the circuit board 2 on a one-to-one basis.

[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
