One end of the ventilation pipe 215 and one end of the connecting pipe 310 are fixedly connected to the outer wall of the air bag 211, and one end of the connecting column 212 is fixedly mounted on the outer wall of the air bag 211. One end of the ventilation pipe 215 is fixedly connected to the inner wall of the airbag 211, one side of the clamping block 213 is fixedly connected to the other end of the connecting column 212, and multiple groups of the slide rails 214 are fixedly installed on the workbench 1. A group of clamping blocks 213 are slidably connected to the slide rail 214. One end of the ventilation pipe 215 is fixedly connected to the outer wall of the airbag 211 and is fixedly connected to the mounting frame 210. The fan 218 is installed inside the mounting tube 217. The bottom of the electrostatic suction cup 114 is fixedly connected to the upper end of the slide rail 214, and the top area of the electrostatic suction cup 114 is smaller than the area of the semiconductor part.

[0019] Preferably, the other end of the ventilation pipe 215 is fixedly connected to one end of the mounting pipe 217, and two groups of support blocks 216 are fixedly installed on the outer wall of the ventilation pipe 215 close to the mounting pipe 217, and the support block 216 is fixedly connected to the lower end of the workbench 1, and the other end of the mounting pipe 217 is fixedly installed with a group of screens 219, and the screens 219 are located at the lower end of the fan 218, and a group of mounting frames 210 are fixedly installed on the workbench 1, and the mounting frames 210 are located on the periphery of the airbag 211, and the mounting frames 210 and the connecting pipe 310 are fixedly connected, and the other end of the connecting pipe 310 is fixedly connected to the air inlet of the electric outlet valve 3, and the air outlet of the electric outlet valve 3 is fixedly connected to one end of the outlet pipe 311.

[0020] Preferably, a group of material boxes 111 are fixedly installed on the workbench 1, and a group of pumps 112 are fixedly installed on the material box 111. A feed port is opened on the material box 111, and the feed port is located on one side of the pump 112. The discharge port of the pump 112 is fixedly connected to one end of the spray pipe 113, and multiple groups of supporting legs 110 are fixedly installed on the bottom of the workbench 1.

[0021] (1) In the present invention, after placing the semiconductor part on the electrostatic suction cup 114, the electrostatic suction cup 114 is started, which will adsorb and fix the part. At this time, the fan 218 is started, and the fan 218 will suck the external air into the inside of the mounting tube 217, and then transmit it to the inside of the air bag 211 through the ventilation pipe 215. When the gas in the air bag 211 increases, it will gradually expand, thereby pushing the connecting column 212 and the clamping block 213 to move forward, so as to press against the four sides of the part.

[0023] Working principle: First, place the semiconductor part on the electrostatic suction cup 114, then start the electrostatic suction cup 114, which will adsorb and fix the part. At this time, start the fan 218, and the fan 218 will suck the external air into the installation tube 217, and then transmit it to the inside of the air bag 211 through the ventilation pipe 215. When the gas in the air bag 211 increases, it will gradually expand, thereby pushing the connecting column 212 and the clamping block 213 to move forward, so as to press against the four sides of the part. Stop starting the fan 218, which can prevent the paint from being sprayed on the workbench 1 during the spraying process. The top area of the electrostatic suction cup 114 is smaller than the area occupied by the part, which can prevent the paint from falling on the electrostatic suction cup. 114, causing pollution and damage to it. At this time, start the pump 112, which will draw the paint inside the material box 111 into the spray pipe 113 and spray it on the parts. When the spraying is completed, open the electric air outlet valve 3. At this time, the gas in the airbag 211 will enter the air outlet pipe 311 from the connecting pipe 310, and finally blow onto the parts, allowing the paint on the parts to dry quickly and speed up work efficiency. A set of air inlet valves are installed in the ventilation pipe 215. When the parts are dried, the fan 218 will also start. Its rotation speed at this moment is lower than the rotation speed when the electric air outlet valve 3 is just closed, so as to ensure that there is a continuous flow of wind blowing out from the air outlet pipe 311, while ensuring that the paint on the surface of the parts is dried, which is convenient and practical.
