Description

Technical Field

[0001] The utility model relates to the technical field of processing mechanical devices for resin lenses, and particularly relates to a lens mold opening machine. Background Technique

[0002] A resin lens is a lens made of organic materials. Inside, it has a polymer chain-like structure that is connected to form a three-dimensional network structure. The intermolecular structure is relatively loose, and there is space for relative displacement between molecular chains. The light transmittance is 84%-90%, with good light transmittance. At the same time, the optical resin lens has strong impact resistance. During the production process of thermosetting resin lenses, two glass molds need to be fixed and resin is injected from the middle. The glass molds will adhere to the resin lens, and the upper and lower glass molds need to be separated to take out the resin lens.

[0003] However, the common removal method in the prior art is manual mold opening. Since manual mold opening requires repetitive operations and takes a long time, it leads to high manual labor intensity. After fatigue occurs, the production efficiency will be reduced. Secondly, using manual labor for mold opening also increases the labor cost. Therefore, a lens mold opening machine is proposed to solve the above problems. Content of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-6 , in the lens mold opening machine in this embodiment, there are a lens classification and sorting module 1, a pressing block module 2, a top block module 3, a cam module 4, a linkage mechanism 5 and a material sensor 6. The pressing block module 2 is located on the left side of the lens classification and sorting module 1, the top block module 3 is located on the right side of the lens classification and sorting module 1, the cam module 4 is located on the right side of the top block module 3, and the linkage mechanism 5 is located on the right side of the cam module 4.

[0026] Specifically, the lens classification and sorting module 1 includes a material distribution platform 101, a scraper cylinder 102 and a material distribution scraper 103. A scraper cylinder 102 is provided at the bottom of the material distribution platform 101, and the other end of the piston rod of the scraper cylinder 102 is fixedly connected with a material distribution scraper 103. The number of material sensors 6 is four, and the four material sensors 6 are respectively located on the left and right sides of the lens classification and sorting module 1. When the lower glass mold falls onto the material distribution platform 101 first after the glass mold is separated from the resin lens, and the material sensor 6 at the material distribution platform 101 senses the material, the material distribution scraper 103 in the lens classification and sorting module 1 moves back and forth driven by the scraper cylinder 102 to classify, push away and sort the resin lens and the glass mold.

[0027] Specifically, the briquetting module 2 includes a briquetting block 201, a first connecting rod 202, and a first horizontal slide 203. A first connecting rod 202 is provided at the bottom of the briquetting block 201, and a first horizontal slide 203 is provided at the bottom of the first connecting rod 202. At the same time, the top block module 3 includes a second connecting rod 301, a second horizontal slide 302, a vertical slide 303, a top block lifting motor 304, and a top block 305. A second horizontal slide 302 is provided at the bottom of the second connecting rod 301. A vertical slide 303 is fixedly connected to the left side of the second connecting rod 301. A top block lifting motor 304 is fixedly installed at the bottom of the second connecting rod 301. A top block 305 is provided above the top block lifting motor 304. The linkage mechanism 5 includes a connecting plate 501, a cam follower 502, and a third horizontal slide 503. The number of connecting plates 501 is two. A cam follower 502 is provided between the two connecting plates 501. The bottom of the cam follower 502 is connected to a third horizontal slide 503. By means of the horizontal driving of the first horizontal slide 203 and the second horizontal slide 302, the top block module 3 and the briquetting module 2 move towards each other to squeeze the lens.

[0028] Specifically, the cam module 4 includes a rotating motor 401, a torque sensor 402, and a cam 403. A torque sensor 402 is provided at the top of the rotating motor 401. The output shaft of the rotating motor 401 is fixedly connected to a cam 403. By setting the torque sensor, the current actual pressure can be fed back, and the cam module 4 adjusts the output pressure according to the feedback value.

[0029] During implementation, the following steps are carried out: When the lens reaches the mold opening mechanism, first, the top block lifting motor 304 drives it to automatically lift to the mold opening position. Subsequently, the cam module 4 makes a rotational movement, driving the top block module 3 and the linkage mechanism 5 to move simultaneously. The top block module 3 and the briquetting module 2 move towards each other to squeeze the lens. Since the lens sizes are different and different pressures are required, the torque sensor 402 in the cam module 4 can feed back the current actual pressure, and the cam module 4 adjusts the output pressure according to the feedback value. Under the squeezing action, the glass mold and the resin lens are separated. Since the briquetting module 2 mechanism is narrow at the top and wide at the bottom, after the glass mold and the resin lens are separated, the lower glass mold falls onto the material distribution platform 101. When the material sensor 6 at the material distribution platform 101 senses the material, the material scraping plate 103 moves back and forth under the drive of the scraping cylinder 102 to classify and push away and sort the resin lens and the glass mold, thus realizing the entire process of lens mold opening.

[0030] In summary, for this lens mold - opening machine, by setting up the lens classification and sorting module 1, the pressing block module 2, the ejector block module 3, the cam module 4, the linkage mechanism 5 and the material sensor 6, according to the contour size of the lens, the ejector block module 3 is automatically lifted to the mold - opening position by the ejector block lifting motor 304. Subsequently, the cam module 4 makes a rotational motion, driving the ejector block module 3 and the linkage mechanism 5 to move simultaneously. The ejector block module 3 and the pressing block module 2 move towards each other to extrude the lens. Since the lens sizes are different and different pressures are required, the torque sensor 402 in the cam module 4 can feedback the current actual pressure, and the cam module 4 adjusts the output pressure according to the feedback value. Under the extrusion effect, the separation of the glass mold and the resin lens is realized, thus achieving the purpose of mold - opening compatible with different lens sizes.

[0031] Moreover, by setting the pressing block module 2 with a narrow upper part and a wide lower part, after the glass mold and the resin lens are separated, the lower glass mold falls onto the material - sorting platform 101. When the material sensor 6 at the material - sorting platform 101 senses the material, the sorting scraper 103 moves back and forth driven by the scraper cylinder 102 to classify, push and sort the resin lens and the glass mold, thus realizing the entire process of lens mold - opening and solving the problem of time - consuming and laborious manual mold - opening.
