Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, in particular to an annealing device. Background Art

[0002] During the hot pressing process of an optical lens blank, it undergoes intense temperature and shape changes. These changes leave thermal stress in the lens blank, which reduces the strength and thermal stability of the lens blank. To eliminate this phenomenon, the lens blank must be annealed after forming. The annealing of the lens blank mainly means placing the lens blank in an annealing device and keeping it at a certain temperature range for a sufficient time or slowly cooling it for a period of time so that no permanent stress and temporary stress exceeding the allowable range are generated.

[0003] When the existing lens blank annealing device (such as a glass lens annealing device disclosed in the patent application No. 201811393056.2) anneals the lens blank, the lens blank is placed on a conveyor belt. As the conveyor belt slowly transports the lens blank, the lens blank enters the heating chamber and the cooling chamber for annealing while being transported. Since the annealing of the lens blank requires a certain amount of time, this requires a longer transportation distance for the lens blank to ensure the annealing effect. However, by increasing the length of the conveyor belt to increase the transportation distance of the lens blank, when arranging the annealing device, the longer conveyor belt will occupy more area, and for a workshop with a small area, the annealing device with the above structure is not applicable.

When the lens blanks reach the lowermost conveyor belt 200, they are conveyed to the tail end by the lowermost conveyor belt 200 and discharged along the discharge outlet 130. This annealing device realizes an increase in the conveying distance of the lens blanks through a plurality of conveyor belts 200 arranged at intervals from top to bottom. When arranging the annealing device, it will not occupy too much area and is suitable for use in workshops with a small area.

One end of each partition plate 430 is fixedly connected to the side wall of the rotating shaft 420, and the other end of each partition plate 430 is rotatably abutted against the cavity wall of the material transfer cavity 411. A material transfer groove 431 is formed between adjacent partition plates 430. The second rotation driving member 440 is fixedly connected to one end of the rotating shaft 420 and is used to drive the rotating shaft 420 to rotate so that the openings of the material transfer grooves 431 are sequentially communicated with the inlet 412 and the outlet 413. By controlling the second rotation driving member 440, the second rotation driving member 440 can drive the rotating shaft 420 to rotate and drive each partition plate 430 to rotate, so that the openings of the material transfer grooves 431 can be sequentially communicated with the inlet 412 and the outlet 413.

[0037] For a better understanding of the present invention, the following combines Figure 1- Figure 4 The working principle of the technical solution of the present utility model will be described in detail:

[0038] When in use, by controlling the first rotation driving member 370, the first rotation driving member 370 can drive the topmost first shaft roller 310 to rotate, and drive the topmost first sprocket group 330 to rotate. Then, through the topmost chain belt group 350, it drives the topmost second sprocket group 340 to rotate, thereby driving the topmost second shaft roller 320 to rotate, and further causing the topmost chain belt 351 to rotate reciprocally, realizing the reciprocal rotation of the topmost conveyor belt 200. Since during the rotation of the topmost second shaft roller 320, through the meshing transmission of the topmost gear and the gear of the next layer, the rotation of the second shaft roller 320 of the upper layer is converted into the reverse rotation of the second shaft roller 320 of the next layer, so that the second shaft roller 320 of the next layer can rotate reversely, realizing that the conveying directions of adjacent conveyor belts 200 are opposite. The lens blank after hot pressing enters the topmost conveyor belt 200 along the feed port 120 and is conveyed by the topmost conveyor belt 200. When the lens blank reaches the end, by controlling the corresponding second rotation driving member 440, the second rotation driving member 440 can drive the rotating shaft 420 to rotate and drive each partition plate 430 to rotate, so that the openings of each material transfer groove 431 can be sequentially communicated with the inlet 412 and the discharge port 413. When the opening of the material transfer groove 431 is communicated with the inlet 412, the lens blank on the topmost conveyor belt 200 enters the material transfer groove 431 along the inlet 412. When the opening of the material transfer groove 431 is communicated with the discharge port 413, the lens blank in the material transfer groove 431 is discharged along the discharge port 413 and reaches the conveyor belt 200 of the next layer, thereby transferring the lens blank on adjacent conveyor belts 200 and realizing the sequential downward conveyance of the lens blank layer by layer. When the lens blank reaches the bottommost conveyor belt 200, it is conveyed to the end by the bottommost conveyor belt 200 and discharged along the discharge port 130. This annealing device realizes an increase in the conveying distance of the lens blank through a plurality of conveyor belts 200 arranged at intervals from top to bottom. When arranging the annealing device, it does not occupy a large area and is suitable for use in a factory building with a small area.

[0039] The annealing device provided by the present utility model has the following beneficial effects:

[0040] (1) The blank lens on the corresponding conveyor belt 200 can be transferred to the next layer of the conveyor belt 200 through the material transfer mechanism 400 provided at the end of the corresponding conveyor belt 200, avoiding direct falling of the blank lens on the upper layer of the conveyor belt 200 onto the lower layer of the conveyor belt 200, which may damage the blank lens.
