[0017] 1. When assembling the vacuum booster of the present invention, the electromagnet can adsorb the upper cover plate of the vacuum booster on the piston plate, the lifting rod can first lower the piston plate out of the sealed cavity, the connecting block and the guide block can respectively limit the piston plate through the connecting groove, the guide groove opposing plate and the connecting plate, thereby limiting the moving distance of the piston plate to avoid excessive lowering of the piston plate causing pressure loss of the internal components due to the upper cover plate. After the vacuum booster is assembled, the electromagnet is first powered off, and then the lifting rod drives the piston plate to rise in the sealed cavity, and the electromagnetic valve is closed at the same time to evacuate the sealed cavity, and the pressure gauge can The pressure in the cavity is displayed in real time. If the vacuum booster has good sealing performance, the air inside it will not leak. If the vacuum booster has unqualified sealing performance, the air in the vacuum booster will leak into the sealed cavity during vacuuming. The sealing performance of the vacuum booster can be determined by observing the value of the pressure gauge. Then the lifting rod drives the piston plate down and re-energizes the electromagnet, so that the electromagnet adsorbs the product. The lifting rod drives the piston plate up to take the product out of the base. The solenoid valve is opened when taking materials to prevent the hydraulic rod from being unable to lift the pressure seat due to the negative pressure inside the sealed cavity.

[0018] 2. When the vacuum booster is assembled in the present invention, when the hydraulic rod drives the pressure seat to descend through the movable plate, the limit rod can keep the movable plate stable, and the limit plate can limit the movable plate to prevent the pressure seat from descending too much and causing pressure damage to the base. After the movable plate contacts the limit plate, the first contact point can contact the second contact point to energize the electromagnetic block, thereby adsorbing the adsorption plate, and pulling the pressure block up through the clamping rod to release the restriction on the pressure plate, so that the pressure plate can slide in the clamping cavity under the action of the clamping spring, and the restriction on the bending block is released, so that the hydraulic rod can take the product out of the base when driving the pressure seat to rise.

[0019] 3. When assembling the vacuum booster of the present invention, the bottom shell of the vacuum booster is first placed in the base, and the telescopic rod can drive the clamping block to slide in the storage cavity to clamp the bottom shell. The slide groove can limit the clamping block through the slider to prevent the clamping block from deflecting and causing the clamping to loosen. After the clamping is completed, the internal components of the vacuum booster are installed inside the bottom shell, and then the hydraulic rod drives the pressure seat to descend, and the upper cover plate is installed on the bottom shell. In the process of the pressure seat descending, the pressure plate can apply pressure to the bending block, thereby driving the bending block to move toward the center of the base to bend the bottom shell. The slide plate can be The slide rail and the slide cavity restrict the bending block to prevent the bending block from tilting and causing bending errors. At the same time, the motor drives the bottom shell to rotate through the turntable, so that the bottom shell can completely cover the upper cover plate to avoid wrinkles when the upper end of the bottom shell is bent, resulting in unqualified sealing. When the pressure seat is fitted with the base, the sealing ring can seal the sealing cavity, so that the sealing cavity becomes a closed space, ensuring the accuracy of the sealing detection. When the pressure plate releases the restriction on the bending block, the spring can drive the bending block to reset through the slide plate, thereby releasing the restriction on the product and preventing the bending block from hindering the movement of the product and making it impossible to take the material.
