[0001] This utility model relates to the field of optical lens manufacturing technology, specifically to a blank lens cooling device for optical lens processing. Background Technology

[0002] Lenses are transparent materials with one or more curved surfaces, made of optical materials such as glass or resin. After polishing, they are often assembled with eyeglass frames to form eyeglasses, used to correct the user's vision and obtain a clear field of vision. In the lens processing, raw materials are first injection molded and cured into a lens blank, which is then polished or otherwise treated to obtain the desired finished lens. After demolding, the blank lens needs to be cooled before proceeding to the next processing step. A Chinese utility model patent with patent number 202421182768.0, entitled "A Blank Lens Cooling Device for Optical Lens Processing," eliminates the need to move the blank lens to a specific cooling area. The cooling process is completed during the feeding process, thus improving the processing efficiency of the blank lens. However, when the above-mentioned cooling device cools the blank lens, because the lens is placed in a placement slot, the lower part of the lens cannot effectively contact the cold air, resulting in uneven cooling and reduced cooling efficiency.

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0020] like Figure 1-7 As shown, this utility model provides a blank lens cooling device for optical lens processing, including a conveying device 1, a placement tray 2 for placing lenses, and a cooling box 3. The cooling box 3 has openings at both ends, through which the conveying device 1 passes. The placement tray 2 passes through the cooling box 3 under the conveying device 1. The placement tray 2 is a square frame structure with openings at the top and bottom. Multiple sets of placement components 4 for placing blank lenses are rotatably mounted on the inner wall of the placement tray 2. A transmission gear 5 is installed in the middle of each placement component 4, and the transmission gear 5 is connected to a rack 6 on the conveying device 1. This utility model places the blank lens to be cooled on the placement components 4 on the placement tray 2. The placement tray 2 passes through the cooling box 3 under the conveying device 1. During this process, the transmission gear 5 engages with the rack 6, and the transmission gear 5 rolls on the rack 6, causing the lens to rotate. This ensures uniform contact between the lens and the cold air in the cooling box 3, resulting in uniform cooling of the lens and improved cooling efficiency.

[0021] The placement assembly 4 consists of multiple placement components 41 for placing blank lenses and connecting rods 42 that sequentially and fixedly connect the multiple placement components 41 together. The connecting rods 42 at both ends are rotatably mounted on the side wall of the placement tray 2; a transmission gear 5 is installed on the connecting rod 42 in the middle. When the blank lens to be cooled is placed in the placement component 41, as the placement tray 2 moves on the conveying device 1, the blank lens placed in the placement component 41 rotates due to the movement and engagement of the transmission gear 5 and the rack 6. This ensures that the lens comes into uniform contact with the cold air in the cooling box 3, resulting in uniform cooling of the lens and improved cooling efficiency.

[0022] The placement component 41 includes two T-shaped placement slots that are hinged to each other. The two placement slots close together to form a cross-shaped placement component 41. The placement slot located on the lower side is the lower placement slot 411, and the placement slot located on the upper side is the upper placement slot 412. The connecting rod 42 connects between the lower placement slots 411. A connecting rod 43 is connected between the upper placement slots 412 located on both sides of the transmission gear 5 to facilitate simultaneous opening or closing. The lens to be cooled is placed in the lower placement slot 411, and the upper placement slot 412 is closed with the lower placement slot 411 to fix the lens in the placement slot. The placement component 41 formed by the lower placement slot 411 and the upper placement slot 412 is cross-shaped, which can make most of the lens area in uniform contact with the cooling agent, thereby making the lens cool evenly and efficiently.

[0023] One of the placement components 41 has a connecting piece 44 at the end of its upper placement groove 412 and lower placement groove 411. The connecting piece 44 is connected by a bolt 45 to lock or open the upper placement groove 412 and lower placement groove 411. After the lens is placed in the placement component 41, the upper placement groove 412 and lower placement groove 411 are closed and fixedly connected by the bolt 45, thereby fixing the lens in place.

[0024] The conveying device 1 includes a fixed platform 11 and conveyor belts 12. The conveyor belts 12 are driven and mounted on rotating shafts 13 located at both ends of the fixed platform 11. There are two conveyor belts 12, each sleeved on both ends of the rotating shafts 13. The rack 6 is fixedly mounted on the fixed platform 11 located between the two conveyor belts 12. The tray 2 is placed on both ends of the two conveyor belts 12 and conveyed forward, facilitating the transmission engagement between the transmission gear 5 and the rack 6.

[0025] The bottom of both ends of the placement tray 2 has notches 21 to facilitate the passage of the rack 6. When the placement tray 2 is conveyed on the conveyor belt 12, the rack 6 enters the placement tray 2 through the notches 21 and contacts the transmission gear 5 to drive the transmission gear 5 to rotate.

[0026] A horizontally arranged connecting pipe 31 is installed at the top of the cooling box 3. Multiple cold air nozzles 32 are evenly connected to the bottom of the connecting pipe 31. The connecting pipe 31 is connected to a refrigeration device via a gas supply pipe 33. The refrigeration device is prior art and is not shown in the attached drawings. The cold air generated by the refrigeration device is transported to the connecting pipe 31 through the gas supply pipe 33 and then ejected from the multiple cold air nozzles 32, maintaining a low-temperature environment in the cooling box 3 and cooling the lens.

[0027] Work process: The blank lens to be cooled is placed in the lower placement groove 411, and the upper placement groove 412 is closed with the lower placement groove 411 and fixedly connected by bolts 45, thereby fixing the lens in place; the two ends of the placement tray 2 are placed on the two conveyor belts 12 and conveyed forward. The placement tray 2 passes through the cooling box 3. When passing through the cooling box 3, the transmission gear 5 and the rack 6 cooperate, and the transmission gear 5 rolls on the rack 6, thereby driving the lens to rotate, so that the lens comes into uniform contact with the cold air in the cooling box 3, thereby cooling the lens evenly and improving the cooling efficiency.

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
