Description

Technical Field

[0001] The invention relates to the technical field of vacuum annealing furnaces, in particular to a vacuum atmosphere protection infrared glass ball precision annealing furnace. Background Art

[0002] The vacuum atmosphere protection infrared glass ball precision annealing furnace is a device used for glass ball annealing. Its principle is to use a vacuum pump to extract the air in the furnace to form a vacuum environment, and then fill it with protective gases such as nitrogen to prevent the glass balls from oxidizing during the annealing process to ensure the annealing quality. Infrared heating elements are then used to generate infrared rays, which are radiated onto the glass balls, so that the glass balls absorb heat evenly, achieving fast, efficient and uniform heating, and providing the required heat for annealing. It is used in the fields of optics, electronics and special glass manufacturing.

[0018] The vacuum atmosphere protection infrared glass ball precision annealing furnace provided by the present invention has the following advantages:

[0019] By providing a vacuum atmosphere annealing furnace body, a cover opening mechanism, a sealing ring, an auxiliary unfolding mechanism and an avoidance groove, by rotating the limit block, since the limit block is threadedly connected to the T-bar through the thread groove, the limit block can be rotated outward along the T-bar and the extrusion limit on the card plate can be released, and the T-bar is pulled to rotate and move out along the slot of the card plate, and the outer end cover is pulled.

[0020] Furthermore, the outer end cover is turned over to drive the clamping plate to be moved out of the vacuum atmosphere annealing furnace body, and the sealing groove and the sealing ring are engaged with each other, so that the sealing performance of the connection between the outer end cover and the vacuum atmosphere annealing furnace body can be improved when the outer end cover is closed.

[0021] Furthermore, by turning the outer end cover over along the main body of the vacuum atmosphere annealing furnace to open, the traction plate can be driven to rotate along the first movable rod, and the first movable rod can apply an outward pulling force to the traction plate. Since the outer end cover rotates with the center of the central axis of the rotating rod, the pulling force direction applied to the traction plate by the first movable rod can be driven to change accordingly, so that the second movable rod slides along the slide groove, driving the second movable rod to apply a pulling force to the inner end cover, so that the inner end cover is turned over and opened along the main body of the vacuum atmosphere annealing furnace under the action of the rotating shaft, which makes it easy to drive the inner end cover to open while the outer end cover is opened, further improving the convenience of opening the end cover, thereby improving the efficiency of taking and placing glass balls;

[0022] Furthermore, under the engagement of the sealing strip and the avoidance groove, the sealing performance of the connection between the inner end cover and the main body of the vacuum atmosphere annealing furnace can be improved. Since the angle of the outer end cover flipping is greater than 90° when the inner end cover flips outward by 90°, when the outer end cover is flipped and closed, the traction plate will first apply a thrust to the inner end cover to flip inward, so that the inner end cover and the outer end cover can be switched in conjunction, further improving the efficiency of the end cover switch and the sealing performance of the connection with the main body of the vacuum atmosphere annealing furnace;

[0023] By providing a vacuum atmosphere annealing furnace main body and an assembly mechanism, the vacuum atmosphere annealing furnace main body is moved, and the docking plate is clamped into the placement rack along the docking groove so that the docking plate is flush with the end of the placement rack, and the bolt is passed through the through hole and rotated. Since the bolt is threadedly connected to the docking plate through the threaded hole, one end of the bolt can be inserted into the threaded hole for limiting, which can facilitate the assembly of the vacuum atmosphere annealing furnace main body and the placement rack. When the vacuum atmosphere annealing furnace main body needs to be transported, the vacuum atmosphere annealing furnace main body and the placement rack can also be disassembled and separated, thereby improving the convenience of use.

The T-shaped retaining ring 47 is snap-fitted and connected with the sealing ring 5 through the sealing groove 48. The sealing ring 5 is elastically set.

[0036] By rotating the limit block 42, since the limit block 42 is threadedly connected to the T-bar 41 through the threaded groove 43, the limit block 42 can be rotated outward along the T-bar 41 and the extrusion limit on the clamping plate 46 can be released, and the T-bar 41 is pulled to rotate and move out along the groove of the clamping plate 46, and the outer end cover 45 is pulled. Under the action of the rotating rod 44, the outer end cover 45 can be reversed and opened along the vacuum atmosphere annealing furnace body 1, so that the clamping plate 46 is moved out of the vacuum atmosphere annealing furnace body 1.
