[0067] The machine body 1 is fixedly connected with an air pump 5 , and an air inlet end of the air pump 5 is fixedly connected with a first air supply pipe 502 . One end of the first air supply pipe 502 away from the air pump 5 is connected with the mounting plate 8 .

[0068] A pressure storage cylinder 2 is fixedly connected to the machine body 1, a second air pipe 501 is fixedly connected to the air outlet end of the vacuum pump 5, the end of the second air pipe 501 away from the vacuum pump 5 is connected to the pressure storage cylinder 2, and an injection pipe 2011 is fixedly connected to the bottom of the pressure storage cylinder 2, and the air outlet end of the injection pipe 2011 faces the placement plate 11.

[0069] Reference Figure 1-Figure 7During welding and installation, the circuit board 12 with the installation slot 1201 is placed on the placement plate 11 and fixed with the elastic clip 1101. The universal robot arm 3 is started to drive the sampler 301 to move to the top of the installation slot 1201. The sampler 301 is used to take photos and samples of the installation slot 1201, and the information of the photos and samples is uploaded to the computer platform 101.

[0070] When the component 13 is laterally offset, the first adjusting screw 801 and the second adjusting screw 802 are rotated for adjustment;

[0071] When the component 13 is longitudinally offset, the third adjusting screw 803 and the fourth adjusting screw 804 are rotated for adjustment;

[0072] The hydraulic cylinder 7 is used to push the mounting plate 8 downward, so that the components 13 extend into the mounting groove 1201 , and the components 13 are welded on the circuit board 12 using a welding gun.

[0074] Reference Figure 1-Figure 2 , Figure 6 During the installation process, the air pump 5 extracts gas through the first air pipe 502, thereby generating negative pressure suction on the mounting plate 8, thereby stably sucking the components 13. The air sucked by the air pump 5 will be transported to the pressure accumulator 2 through the second air pipe 501, and the gas entering the pressure accumulator 2 will be stored in the pressure accumulator 2.

[0075] It should be noted that the vacuum pump 5 is a powerful pump available on the market, which can stably absorb the components 13 .

At this time, the gas in the pressure storage cylinder 2 will be instantly ejected through the jet pipe 2011. The ejected gas will blow on the circuit board 12, thereby effectively blowing off the welding slag on the circuit board 12, thereby ensuring the surface cleanliness of the circuit board 12.

[0078] A slot 1102 is formed on the placement plate 11 , and the slot 1102 matches the circuit board 12 .

[0089] Step 6: Use the sampler 301 to take a photo of the bottom surface of the component 13 on the mounting plate 8, and upload the photo-driven information to the computer platform 101;

[0090] Step 7: Compare the two uploaded shooting information through the computer platform 101, and analyze and display the offset path of the installation plate 8 according to the comparison result;

[0091] Step 8: When the component 13 is laterally offset, the first adjusting screw 801 and the second adjusting screw 802 are rotated to adjust; when the component 13 is longitudinally offset, the third adjusting screw 803 and the fourth adjusting screw 804 are rotated to adjust;

[0092] Step nine: Use the hydraulic cylinder 7 to push the mounting plate 8 downward, so that the components 13 extend into the mounting groove 1201 , and use a welding gun to weld the components 13 on the circuit board 12 .

[0093] The present invention can stably adsorb components 13 through a powerful vacuum pump 5, making it convenient for the mounting plate 8 to drive the components 13 to move in position. At the same time, through the sampler 301 arranged on the body 1, the mounting slot 1201 and the components 13 can be effectively sampled, and compared and analyzed through the computer platform 101, thereby facilitating the staff to manually adjust the adjustment part. Through the multiple sets of adjustment screws arranged on the mounting plate 8, the components 13 can be accurately installed at the predetermined position of the circuit board 12, thereby reducing the possibility of offset during welding and improving the welding installation accuracy.
