Specifically, the second sealing rings 179 are two and are O-shaped sealing rings, and by providing the two O-shaped sealing rings, the movable cylinder 173 and the fixed cylinder 171 can be connected in a sealing manner, so that the leakage is avoided, and the sealing effect is further ensured.

It should be noted that in this embodiment, since the movable cylinder 173 needs to move relative to the fixed cylinder 171, sealing lubricant needs to be applied on the two second sealing rings 179 during actual processing, so as to prevent the movable cylinder 173 from rapidly wearing the second sealing rings 179 during the movement, and at the same time, the sealing lubricant further improves the sealing effect.

In this embodiment, a first vacuum channel 161a communicating with the external space is opened on the first joint surface 160 between two adjacent first sealing rings 161, and the first vacuum channel 161a is used for pumping air between the two first sealing rings 161, so that the first sealing rings 161 are adsorbed on the second joint surface 180.

Specifically, the number of the sealing ring grooves 163 is two, the two first sealing rings 161 are respectively and correspondingly disposed in the two sealing ring grooves 163, and the depth of each sealing ring groove 163 is smaller than the diameter of the first sealing ring 161, so that the first sealing ring 161 is only partially accommodated in the two sealing ring grooves 163 and protrudes outward, and therefore when the movable cylinder 173 abuts against the second joint surface 180, the first sealing ring 161 can abut against the second joint surface 180 and be squeezed, and a sealing effect is achieved.

It should be noted that, in the present embodiment, a double seal structure is adopted, and by providing the first vacuum channel 161a between the two first seals 161, there is no fear of leakage risk, even if one or two of the two first seals 161 are partially damaged, since the vacuum is exhausted from the middle portion, the atmosphere is not brought into the container to contact with the workpiece, and the workpiece is further prevented from contacting with the atmosphere.

In this embodiment, a second vacuum passage 179a communicating with the external space is provided in the fixed cylinder 171 between two adjacent second seal rings 179, and the second vacuum passage 179a is used to suck air between the two second seal rings 179 to adsorb the second seal rings 179 to the inner circumferential surface of the movable cylinder 173.

In the present embodiment, the two second seal rings 179 are provided in parallel with each other and are both provided on the outer peripheral surface of the fixed cylinder 171. The gap between the two second sealing rings 179 is small, so that the two second sealing rings 179 always abut against the inner circumferential surface of the movable cylinder 173 during the movement of the movable cylinder 173.

In the present embodiment, the outer circumferential surface of the fixed cylinder 171 is provided with a fixed ring block 178, and a second seal ring 179 is fitted in the fixed ring block 178. Specifically, two parallel ring grooves are formed in the fixed ring block 178, the two second sealing rings 179 are partially accommodated in the two ring grooves and protrude outward, and the protruding portions of the two second sealing rings 179 are abutted against the inner circumferential surface of the movable cylinder 173.

It should be noted that, in the present embodiment, a double seal ring structure is adopted, and the second vacuum channel 179a provided between the two second seal rings 179 is used for vacuum pumping, so that there is no fear of leakage risk, even if one or two of the two second seal rings 179 are partially damaged, since the vacuum is exhausted in the middle portion, the atmosphere is not brought into the container to contact the workpiece, and the workpiece is further prevented from contacting the atmosphere.

Specifically, here the bearing ring plate 191 is rectangular frame-shaped, and the ring is established around the second opening 151, and adjusting bolt 193 is four, and four adjusting bolt 193 set up respectively in four apex angle departments of bearing ring plate 191, through adjusting four adjusting bolt 193's pretightning force respectively, can realize bearing ring plate 191's installation angle's fine setting to can finely tune bearing ring plate 191 according to the sealed condition, make first sealing washer 161 can extrude to support and hold on bearing ring plate 191, guarantee sealed effect.

It should be noted that, in this embodiment, the width direction of the carrier ring plate 191 refers to a direction in which the geometric center position of the carrier ring plate 191 diverges outward, that is, the narrow edge direction of the carrier ring plate 191, and the adjusting bolt 193 is disposed on the outer side in the width direction to abut the inner side against the elastic sealing ring 155, so that when the pretightening force is adjusted, the extrusion stress between the carrier ring plate 191 and the elastic sealing ring 155 can be changed, thereby achieving the fine adjustment of the carrier ring plate 191.

In summary, the sealed transfer device 100 provided in this embodiment has the following transfer process: in actual sealing, the driving unit 175 drives the movable cylinder 173 to move and press the movable cylinder 173 against the second joint surface 180 of the carrier ring plate 191, the first vacuum channel 161a and the second vacuum channel 179a are evacuated by the vacuum pump, so that the gap between the first sealing ring 161 is evacuated, the gap between the second sealing ring 179 is evacuated, so that the first sealing ring 161 is adsorbed on the second joint surface, the second sealing ring 179 is adsorbed on the inner circumferential surface of the movable cylinder 173, after the vacuum degree reaches the standard within a predetermined time, the first vacuum sealing door 135 and the second vacuum sealing door 153 are opened, the workpiece is conveyed from the first opening 131 to the second opening 151 by the conveying unit 133, after the conveying unit is conveyed, the conveying unit returns to the heat preservation chamber, the first vacuum sealing door 135 and the second vacuum sealing door 153 are closed, and the vacuum pump is stopped, the atmosphere is then opened and the movable barrel 173 is finally pulled back to the initial position by the driving member 175.

The sealed transfer device 100 provided by the embodiment realizes a double-sealing structure by using the two first sealing rings 161 at the first joint surface 160 and the second joint surface 180, realizes a double-sealing structure by using the two second sealing rings 179 between the fixed cylinder 171 and the movable cylinder 173, does not need to worry about leakage, and simultaneously performs a vacuum pumping action by arranging a vacuum channel, so that even if a sealing material is damaged in a transfer process, the atmosphere cannot be brought into a container to react with a workpiece due to a vacuum exhaust effect. Meanwhile, the leakage condition is confirmed through the vacuum exhaust time, the damage of the sealing material can be found as soon as possible, and the overall safety is improved. And the current installation difficulty is very high. The parallelism and perpendicularity of the conveyance side and the reception side and the amount of clearance between the apparatuses are required to be strict. In the embodiment, the difficulty is greatly reduced due to the use of the adjusting bolt. Therefore, the amount of play is no problem as long as it is within the movable range of the link sliding portion.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
