Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical lens production equipment, specifically to a lens cutting and conveying device. Background Technology
[0002] After cutting, existing lens cutting fixtures typically require a robotic arm to drive a suction cup device. The suction cup's nozzle picks up the lens and sprue column, and then the material is separated. When the lens diameter is less than 1cm, the corresponding nozzle diameter also decreases. If the nozzle diameter is too small, the negative pressure inside the nozzle cannot quickly return to normal pressure, or even cannot return to normal pressure at all. This often results in the inability to properly detach and eject the material, thus affecting production efficiency. Utility Model Content
[0003] Therefore, the purpose of this utility model is to provide a lens cutting and conveying device to improve the separation efficiency after lens cutting.
[0004] A lens cutting and conveying device includes a cutting fixture and a conveying fixture; the cutting fixture is fixedly connected to the conveying fixture, and the conveying fixture is located below the cutting fixture; the cutting fixture has a plurality of cutting stations, each cutting station has a material discharge hole, and the conveying fixture has a plurality of funnels, each funnel being connected to at least one material discharge hole of the cutting station.
[0005] The lens cutting and conveying device described in this utility model eliminates the method of picking up lenses. Instead, a conveying fixture is added to the bottom of the cutting fixture. After the lens is cut on the cutting fixture, it falls from the drop hole into the funnel and is then conveyed out of the lens cutting and conveying device by the conveying fixture. This can effectively solve the problem of abnormal material throwing and improve production efficiency.
[0006] As a preferred embodiment, a collection conduit is also included, which is connected to the conveying fixture and located at the bottom of the conveying fixture. The lens is collected and conveyed out of the fixture device through the collection conduit.
[0007] As a preferred embodiment, each cutting station is equipped with a positioning hole. The positioning hole allows for precise positioning of the sprue column, improving cutting accuracy and efficiency.
[0008] As a preferred embodiment, each cutting station is provided with several discharge holes, which are arranged in a circle around the positioning hole, and the discharge holes are connected to the funnel. Since the lens separates from the sprue column during cutting, the sprue column will experience a certain offset. The lens is cut on the discharge holes, and after cutting, it can fall directly into the conveying fixture, avoiding interference between the already cut lens, the uncut lens, and the sprue column.
[0009] As a preferred embodiment, the bottom of the conveying fixture is perforated and has a dust suction port, the diameter of which is smaller than the outer diameter of the lens. The dust generated during the cutting process is absorbed through the dust suction port.
[0010] As a preferred embodiment, the system also includes a negative pressure vacuum cleaner connected to the suction port. The negative pressure vacuum cleaner is used to generate negative pressure to absorb the dust produced during the cutting process.
[0011] As a preferred embodiment, the four cutting stations are arranged in a rectangular pattern, and each of the conveying fixtures is connected to the four rectangularly arranged cutting stations.
[0012] As a preferred embodiment, the cutting fixture is further provided with a fixing hole, and the conveying fixture is further provided with a positioning pin. The cutting fixture and the conveying fixture are positioned and detachably connected through the fixing hole and the positioning pin. The detachable connection between the cutting fixture and the conveying fixture facilitates the replacement of different cutting fixtures and the cleaning of the conveying fixture.
[0013] As a preferred embodiment, the diameter of the lens is less than 1 cm. Attached Figure Description

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0022] like Figs. 1-3 As shown, the lens cutting and conveying device of this utility model includes a cutting fixture 1, a conveying fixture 2, a collection pipe 3, and a negative pressure vacuum cleaner (not shown). The cutting fixture 1 is provided with a fixing hole 14, and the conveying fixture is provided with a positioning pin 23. The cutting fixture 1 and the conveying fixture 2 are positioned and detachably connected through the fixing hole 14 and the positioning pin 23. The collection pipe 3 is fixedly connected to the conveying fixture 2. The conveying fixture 2 is located below the cutting fixture 1, and the collection pipe 3 is located below the conveying fixture 2. The cutting fixture 1 has 16 cutting stations 11, with 4 cutting stations 11 arranged in a rectangle. Each cutting station 11 has 1 positioning hole 12 and 6 material discharge holes 13. The 6 material discharge holes 13 are arranged in a circle with the positioning hole 12 as the center. The conveying fixture 2 has four funnels 21, each funnel 21 is connected to four cutting stations 11 arranged in a rectangle. The bottom of the conveying fixture 2 is fixedly connected to the collection pipe 3. The bottom of the conveying fixture 2 is hollowed out and a dust suction port 22 is provided.

[0023] The working principle of the lens cutting and conveying device of this utility model is as follows:
[0024] After injection molding, the sprue column is plate-shaped with protruding positioning blocks. Lenses are arranged in a circle around the positioning column. The injection-molded sprue column is moved into the cutting station 11 corresponding to the cutting fixture 1. The positioning blocks are inserted into the positioning holes 12 to position the sprue column. Then, the lens located above the blanking hole 13 is cut by a laser machine. After the lens is cut, it falls from the funnel 21 into the conveying fixture 2, and then into the collection pipe 3, completing the cutting and collection of the lens. The dust generated during the cutting process is collected by the dust suction port 22.
[0025] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent.
