Description

Background
The sealing machine is a machine for automatically performing sealing operation, and the mechanical structure of the applied automatic sealing machine is different according to different products to be sealed, for example, the bag sealing machine and the can sealing machine are completely different sealing machines, so that the sealing machines of products packaged in different forms are different, products packaged in multiple fields are difficult to be commonly used, and most of the sealing machines are relatively obvious in application to the mouth to be sealed without being performed in special environments.
For the existing workpiece with special property, the workpiece contains substances possibly harmful to human bodies, and the internal substances need to be stabilized by filling special high-pressure gas (the gas possibly harmful to human bodies is adopted by the high-pressure gas), so the workpiece is provided with a port filled with the high-pressure gas and is a tiny hole, the tiny hole needs to be sealed after the high-pressure gas is filled to prevent the internal substances or the gas from being leaked, and all operations of the workpiece before and after the high-pressure gas is filled need to be performed in a sealed environment because the substances contained in the workpiece and the filled high-pressure gas possibly have harm. The structure of the workpiece with special properties is shown in fig. 5, and the workpiece comprises a workpiece main body 10 with an elongated air inlet pipe 101 and a needle-shaped air charging pipe 102 connected to the outer port of the elongated air inlet pipe 101, wherein the diameter of the outer port of the air charging pipe 102 is generally not more than 1 millimeter, the air charging pipe is high-pressure micropores, high-pressure air is charged into the workpiece main body from the high-pressure micropores, the high-pressure micropores of the air charging pipe 102 are sealed to keep the internal pressure stable after the high-pressure air charging pipe is charged, so that stable internal substances are realized, and the high micropores of the smaller air charging pipe 102 are sealed, and the hole sealing is realized by plugging a small granular hole sealing object into the high micropores of the air charging pipe 102. However, the plugging operation using small granular plugging objects plugged into the high micropores of the gas tube 102 of not more than 1 mm is obviously visible and requires very high precision. If mechanical automation is to be realized to effectively seal micro-holes, a mechanical device capable of realizing extremely high precision is needed, but at present, no reliable and effective mechanical device is suitable for automatic micro-hole sealing of the operation, and because of special requirements of an operation environment and extremely high precision requirements of the tiny characteristics of the needle-shaped inflation tube, the micro-hole sealing operation difficulty is extremely high and the mechanical automation is extremely difficult to realize, most of the operation processes are mainly performed manually in a closed environment at present, the manual participation operation is more, and more problems exist, so that the prior micro-hole sealing operation mode of the workpiece is urgently improved, and meanwhile, an automatic machine capable of achieving the requirements for micro-hole sealing operation is also urgently researched and developed.

s8, starting a multi-axis Cartesian coordinate moving device, firstly, driving a workpiece placing frame to move by adjusting to realize the movement of the fourth sliding mounting frame in the X-axis direction so that a workpiece inflation tube on a workpiece positioning plate corresponds to a micropore sealing station, and driving a glue carrying supporting plate to move by adjusting to realize the movement of the third sliding mounting frame in the X-axis and Y-axis direction so that glue drops on a glue carrying sheet correspond to the positions right below the workpiece inflation tube; then, the glue carrying support plate is driven to move by adjusting the movement in the positive direction of the Z axis of the third sliding mounting frame so that glue drops on the glue carrying sheet are contacted with the gas filled tube of the workpiece and glue is adhered on the gas filled tube to seal micropores of the workpiece, and then, the glue drops on the glue carrying sheet are separated from the gas filled tube of the workpiece by adjusting the movement in the negative direction of the Z axis of the third sliding mounting frame;
s9, waiting for glue to adhere to the air charging pipe and seal micropores of the air charging pipe according to preset time;
s10, firstly, adjusting the closed operation box to be in a negative pressure vacuum state through a gas distribution system, and stopping vacuumizing when the negative pressure vacuum value in the closed operation box reaches a preset negative pressure vacuum value; the pressure of the pressure container is released slowly through the air distribution system, the pressure is released to the atmospheric pressure state, or the pressure of the pressure container is released slowly through the air distribution system and is regulated to be in a negative pressure vacuum state slowly, and then the air is slowly filled; then, opening a taking and placing cabin door of the pressure container, taking out the film carrier from the film carrier ring and placing the film carrier in the closed operation box, disconnecting the workpiece positioning plate in the pressure container from the workpiece placing frame, taking out the film carrier and placing the film carrier in the closed operation box, and then positioning and fixing the workpiece positioning structure and the micropore positioning structure, taking down the film carrier and sealing the film carrier and packaging the film carrier;
S11, taking out the work piece which is sealed and packaged in the sealed operation box.
10. The method of claim 9, wherein in step S8, the operator observes the adjustment state of the multi-axis cartesian coordinate moving device in the pressure vessel, the corresponding state of the gas tube and the glue drop of the workpiece and the state of the glue covering the gas tube to seal the micro-holes through multiple angles by the visual operation control system, and the adjustment movement of the multi-axis cartesian coordinate moving device can be controlled by the visual operation control system.
