[0022] Example:

[0023] See also Figure 1-4 The utility model provides a technical solution: a material rejection device for an insertion machine, comprising an electric slide rail 1, a rejection shell 3 is slidably installed at the bottom of the electric slide rail 1, an electric telescopic rod 4 is installed at the bottom of the rejection shell 3, and the bottom of the movable rod of the electric telescopic rod 4 is connected to an adsorption head 6 through a rotating structure 5. The adsorption head 6 adsorbs the material through the negative pressure airflow generated by a negative pressure pump 14, and a negative pressure cavity 13 is provided inside the adsorption head 6. A large adsorption hole 10 and a small adsorption hole 8 are respectively provided on the left and right sides of the bottom of the negative pressure cavity 13. Electric control valves 9 are installed in the middle of the large adsorption hole 10 and the small adsorption hole 8. Wind speed sensors 7 are installed on the tops of the inner walls of the large adsorption hole 10 and the small adsorption hole 8. When larger materials are rejected, the small adsorption hole 8 is closed to prevent the large materials from being rejected. The electric control valve 9 of the attached hole 8 is then started, and the negative pressure pump 14 is started to form a negative pressure in the negative pressure chamber 13 through the air pipe 12, and then the electric control valve 9 of the large adsorption hole 10 is opened, so that the large adsorption hole 10 adsorbs the corresponding components. After the adsorption is completed, the wind speed detected by the wind speed sensor 7 in the large adsorption hole 10 decreases synchronously, indicating that the adsorption of the components is completed. Similarly, when smaller materials are rejected, the electric control valve 9 of the large adsorption hole 10 is closed, and then the negative pressure pump 14 is started to form a negative pressure in the negative pressure chamber 13 through the air pipe 12, and then the electric control valve 9 of the small adsorption hole 8 is opened, so that the small adsorption hole 8 adsorbs the components. After the adsorption is completed, the wind speed detected by the wind speed sensor 7 in the small adsorption hole 8 decreases synchronously, indicating that the adsorption of the components is completed.

[0024] Among them, a negative pressure pump 14 is installed inside the removal shell 3, and an air pipe 12 is connected to the bottom of the negative pressure pump 14. The end of the air pipe 12 is connected to the negative pressure chamber 13 of the adsorption head 6. The negative pressure pump 14 has an inlet and an outlet suction nozzle and an exhaust nozzle, and can continuously form a vacuum or negative pressure (relative vacuum) at the inlet, and a slight positive pressure is formed at the exhaust nozzle, so that the negative pressure at the inlet can adsorb the object. The negative pressure pump 14 is connected to the negative pressure chamber 13 of the adsorption head 6 through the air pipe 12, and the adsorption of components is completed through the large adsorption holes 10 and small adsorption holes 8 at the bottom of the negative pressure chamber 13.

[0025] Among them, the electric control valve 9 of the large adsorption hole 10 and the electric control valve 9 of the small adsorption hole 8 are NOT connected, the small adsorption hole 8 is used to adsorb components between 0.1-0.5mm, and the large adsorption hole 10 is used to adsorb components larger than 0.5mm. The electric control valve 9 of the large adsorption hole 10 and the electric control valve 9 of the small adsorption hole 8 are started one by one, the small adsorption hole 8 is mostly used to remove smaller components such as resistors and small capacitors, while the large adsorption hole 10 is often used to remove larger components such as capacitors with larger farads and relays.

[0026] Among them, a stroke sensor 2 is installed on the right side of the electric slide rail 1, and the signal output end of the wind speed sensor 7 is connected to the signal input end of the electric slide rail 1. The stroke sensor 2 detects the position of the rejection shell 3 on the electric slide rail 1. When the wind speed sensor 7 detects that the wind speed drops and completes the adsorption of the component, the electric slide rail 1 is started to move.

[0027] Among them, a rotating motor 11 is installed on the outer wall of the rotating structure 5, and the shaft of the rotating motor 11 is connected to the adsorption head 6. After the components are inserted, in the area where the components are relatively concentrated, the adsorption head 6 cannot directly approach the components from above. Then, by starting the rotating motor 11 to drive the angle of the adsorption head 6 to adjust, it approaches the components to be removed from an inclined direction, which can deal with the situation where components are difficult to remove and avoid the situation where a component on a circuit board with concentrated components is difficult to remove.

[0028] Among them, the signal output ends of the two groups of wind speed sensors 7 are connected to the signal input ends of the rotating structure 5. When the wind speed signals of the two groups of wind speed sensors 7 do not drop, the rotating structure 5 is started. When the large adsorption holes 10 and the small adsorption holes 8 cannot adsorb the components anyway, the rotating structure 5 is started to adjust different angles for adsorption.

[0029] The signal output end of the stroke sensor 2 is connected to the signal input end of the electric telescopic rod 4. The stroke sensor 2 detects that the rejection shell 3 moves to a predetermined position and starts the electric telescopic rod 4, thereby making the adsorption head 6 approach the components to be rejected.

[0030] The working principle of the embodiment of the utility model is as follows: the electric slide rail 1 is started to drive the rejection shell 3 to move to the top of the component to be rejected, and then the electric telescopic rod 4 is started to make the adsorption head 6 close to the component to be rejected, and the negative pressure pump 14 is connected to the negative pressure chamber 13 of the adsorption head 6 through the air pipe 12, and the adsorption of the components is completed through the large adsorption hole 10 and the small adsorption hole 8 at the bottom of the negative pressure chamber 13. When the larger material is to be rejected, the electric control valve 9 of the small adsorption hole 8 is closed, and then the negative pressure pump 14 is started to form a negative pressure in the negative pressure chamber 13 through the air pipe 12, and then the electric control valve 9 of the large adsorption hole 10 is opened, so that the large adsorption hole 10 adsorbs the corresponding component. After the adsorption is completed, the wind speed sensor 7 in the large adsorption hole 10 is The detected wind speed decreases synchronously, indicating that the adsorption of components is completed. Similarly, when smaller materials are to be removed, the electric control valve 9 of the large adsorption hole 10 is closed, and then the negative pressure pump 14 is started to form a negative pressure in the negative pressure chamber 13 through the air pipe 12, and then the electric control valve 9 of the small adsorption hole 8 is opened, so that the small adsorption hole 8 adsorbs the corresponding components. After the adsorption is completed, the wind speed detected by the wind speed sensor 7 in the small adsorption hole 8 decreases synchronously, indicating that the adsorption of components is completed. When the components to be removed are located in the concentrated area of ​​​​circuit board components, the adsorption head 6 cannot directly approach the components from above, and then the rotation motor 11 is started to drive the adsorption head 6 to adjust its angle, and approach the components to be removed from the inclined direction;

[0031] When the wind speed sensor 7 detects that the wind speed has dropped and the adsorption of the component is completed, the electric telescopic rod 4 is started to move the component away from the original plug-in hole, and then the electric slide rail 1 is started to move to complete the removal of the component.
