Description

TECHNICAL FIELD

[0002] The vacuum glove box, also referred to as a glove box, is a commonly used device for providing such a closed space and closed environment, which is widely used in factories, laboratories and analysis rooms. By filling high-purity inert gas into the glove box and circulating and filtering out active substances such as oxygen and moisture, the material can be safely put in and taken out, and the operation, reaction and testing can be carried out freely in the oxygen-free and moisture-free state.

[0003] The existing glove box mainly comprises a glove box body and a transition bin. The transition bin comprises an inner door and an outer door. The inner door is installed at the connection of the glove box body leading to the transition bin, and the door is arranged at the other end of the transition bin. An air spring or a rotating handle is installed on the inner door for sealing, and the outer door is directly sealed by the handle. The process of using the transition bin is as follows: when the inner door is opened, the outer door must be in a closed state; when the outer door is opened, the inner door must be in a closed state.

The design of the limiting rod 11 limits the movement track of the contact head 791 to avoid skewing. The rotating rod 76 is an arc-shaped rod, and the sliding rail 790 is an arc-shaped rail. The design of the arc-shaped rotating rod 76 and the arc-shaped sliding rail 790 is conducive to reducing the friction between the rotating rod 76 and the sliding rail 790.

While the rotating shaft 72 rotates, the rotating rod 76 will be driven to rotate, when the rotating rod 76 rotates into the slide rail 790, the connecting plate 79 will be extruded by the rotating rod 76, the connecting plate 79 extrudes the spring 78, the connecting plate 79 drives the contact 791 to move into the contact seat 77, until the contact 791 and the inside of the contact seat 77 are completely matched, at this time the power of the electric cylinder 792 is turned on, the telescopic end of the electric cylinder 792 drives the connecting block 793 to move upwards, the connecting block 793 drives the sealing door 794 to move upwards, the feeding port 4 is opened, and then the object is placed on the placement disc 75.

Further, the structure drives the rotating rod 76 to rotate by the motor 71, the rotating rod 76 extrudes the connecting plate 79, so that the contact 791 and the contact seat 77 are completely matched, the electric cylinder 792 drives the sealing door 794 to move upwards, and the object is placed, and then the contact 791 and the contact seat 77 are separated, air is extracted, high-purity inert gas is filled, and the placement disc 75 rotates the object into the glove box body 1, so that the air in the outside enters the glove box body 1 and the product oxidation is avoided.

[0032] Please refer to Figures 2 to 3As shown, the top end of the transition bin 2 is provided with a blowing mechanism 8, which comprises a gas bag 81 fixedly connected to the top end of the transition bin 2, the gas outlet end of the gas bag 81 is fixedly connected with a dust removal pipe 82, the other end of the dust removal pipe 82 is towards the contact 791, the outer side of the dust removal pipe 82 is fixedly connected with a hoop 84, the bottom end of the hoop 84 is fixedly connected with a straight rod 83. The top end of the transition bin 2 is rotationally connected with a rotating plate 12, and the end face of the rotating plate 12 is in contact with the gas bag 81. When the rotating rod 76 rotates, the rotating plate 12 is extruded, and the rotating plate 12 extrudes the gas bag 81, which is beneficial to improve the extrusion degree of the gas bag 81, so that more gas can be blown out. The top end of the transition bin 2 is fixedly connected with a limiting block 13, and the side surface of the limiting block 13 is in contact with the rotating plate 12. The limiting block 13 limits the rotation angle of the rotating plate 12, avoids the gas bag 81 from recovering too quickly, and causes the rotating plate 12 to rotate reversely too much, so that the rotating rod 76 cannot extrude the rotating plate 12 again.

[0033] In this embodiment, in operation, the rotating rod 76 extrudes the gas bag 81 during rotation, and the gas in the gas bag 81 enters the dust removal pipe 82 and is then discharged. The discharged gas blows to the surface of the contact 791 and the inside of the contact seat 77, removing the dust adhered thereto. Furthermore, the structure uses the rotating rotating rod 76 to extrude the gas bag 81, so that the gas in the gas bag 81 is discharged through the dust removal pipe 82, removing the dust adhered to the surface of the contact 791 and the inside of the contact seat 77, avoiding the occurrence of poor contact caused by too much dust.

[0034] Working principle: in working, the suction pipe 5 and the inflation pipe 6 are connected with the outside air suction source and the air inlet source respectively, the power supply of the motor 71 is turned on, the output end of the motor 71 drives the rotating shaft 72 to rotate, the rotating shaft 72 drives the rotating disc 73 to rotate, the rotating disc 73 drives the arc baffle 74, the arc baffle 74 drives the placement disc 75 to rotate, so that the placement disc 75 rotates into the transition bin 2, at this time the back of the arc baffle 74 blocks the channel 3, and sealing is performed. While the rotating shaft 72 rotates, the rotating rod 76 will rotate, when the rotating rod 76 rotates into the slide rail 790, the connecting plate 79 will be extruded by the rotating rod 76, the connecting plate 79 extrudes the spring 78, the connecting plate 79 drives the contact 791 to move into the contact seat 77 until the contact 791 and the inside of the contact seat 77 are completely attached, at this time the power supply of the electric cylinder 792 is turned on, the telescopic end of the electric cylinder 792 drives the connecting block 793 to move upwards, the connecting block 793 drives the sealing door 794 to move upwards, the feeding port 4 is opened, and then the articles are placed on the placement disc 75. The motor 71 drives the rotating rod 76 to rotate by a small angle, so that the rotating rod 76 and the slide rail 790 are separated, the contact 791 and the contact seat 77 are separated, the telescopic end of the electric cylinder 792 drives the sealing door 794 to move downwards, and the channel 3 is sealed again, at this time the arc baffle 74 rotates by a small angle synchronously, but still seals the channel 3, and then the suction pipe 5 sucks out all the air in the transition bin 2, the inflation pipe 6 inputs high-purity inert gas into the transition bin 2, and then the motor 71 continues to drive the placement disc 75 to rotate, the placement disc 75 rotates the articles into the glove box body 1, and the articles are taken out by using the gloves on the glove box body 1 for operation. Further, the structure drives the rotating rod 76 to rotate by the motor 71, the rotating rod 76 extrudes the connecting plate 79, so that the contact 791 and the contact seat 77 are completely attached, the electric cylinder 792 drives the sealing door 794 to move upwards, the articles are placed, and then the contact 791 and the contact seat 77 are separated, the air is extracted, the high-purity inert gas is filled, and the placement disc 75 rotates the articles into the glove box body 1, so that the outside air enters the glove box body 1 and the product oxidation is avoided.

[0035] In the process of rotating the rotating rod 76, the rotating rod 76 will extrude the air bag 81, the gas in the air bag 81 will enter the dust removal pipe 82, and then be discharged. The discharged gas blows on the surface of the contact 791 and the inside of the contact seat 77 to remove the dust adhered thereto. Further, the structure extrudes the air bag 81 by the rotating rotating rod 76, so that the gas in the air bag 81 is discharged through the dust removal pipe 82 to remove the dust adhered to the surface of the contact 791 and the inside of the contact seat 77, avoiding the situation that too much dust causes poor contact.
