Description

Technical Field

[0001] The present invention relates to the technical field of optical lenses, and in particular to a method for processing a resin optical lens. Background Art

[0002] Resin optical lenses are made of organic materials and feature light weight, high transparency, impact resistance, easy molding, and dyeability. They hold a leading position in the competitive eyewear market. The production of thermoplastic optical resin lenses requires first wrapping two molds with tape and then collecting them. Workers then manually inject resin into the molds, placing the molds with the resin injected in an oven. After heat treatment, the molds are opened to produce the resin optical lens blanks. However, this process has the following drawbacks:

[0003] 1. Currently, when workers inject resin into a mold secured with tape, they first need to peel off the tape. When the connection between the tape and the mold is exposed, the resin is injected into the mold. Because the tape is thin and transparent, peeling it off is difficult. At the same time, after the resin infusion is completed, the worker needs to put the peeled tape back on. This process is relatively complicated, not only consuming a lot of manpower, but also reducing the efficiency of resin infusion.

[0004] 2. When pouring resin into the mold, the worker usually holds the mold with one hand and controls the resin pouring switch with the other hand to pour resin into the mold. This means that one person can only control one pouring device and can only pour resin into one mold at a time. This is inefficient and not suitable for mass production. Summary of the Invention

[0005] The object of the present invention is to provide a method for processing a resin optical lens, which is not only simple to operate but also can efficiently realize the processing of the resin optical lens.

[0020] Beneficial effects

[0021] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0022] 1. By placing multiple molds in a material box, and arranging a track groove and a convex rod to cooperate, and arranging a first through hole in the first slide bar to cooperate with the second through hole in the working block, so that when the working block rotates and drives the first slide bar to a horizontal position facing the material box, the convex rod is controlled to move by the track groove, driving the first slide bar to extend. At this time, the suction cup on the first slide bar is pressed against the mold in the material box, and the first through hole in the first slide bar is connected to the second through hole in the working block, and at this time, the second through hole in the working block is connected to the first flow channel on the connecting frame. Since the first flow channel is connected to the vacuum source, the air in the suction cup can be extracted by the external vacuum machine, so that the mold is adsorbed on the suction cup, and as the working block rotates, the mold is taken away from the material box, the first slide bar moves along the track groove, so that the second through hole on the working block is disconnected from the first through hole in the first slide bar, and the pressure of the seal is maintained to maintain the vacuum in the suction cup, so that the mold can be kept adsorbed on the suction cup all the time. By continuously rotating the working block, all the suction cups can be adsorbed on the mold, completing automatic loading, saving manpower and improving efficiency.

[0023] 2. By arranging the cooperation of the track groove and the convex rod, when the working block drives the first slide bar to the vertical downward position, the cooperation of the track groove and the convex rod drives the first slide bar to extend, and at this time the suction cup drives the mold to the conveyor belt. Since the first through hole in the first slide bar is connected to the second through hole in the working block, and the second through hole on the working block is connected to the second flow channel on the connecting frame, external air will enter the suction cup, so that the suction cup and the mold are separated. Then, after the resin infusion is completed, the mold can be automatically unloaded without manual operation, saving manpower. Moreover, when unloading is required, by controlling the working block to rotate one circle, a new batch of molds can be adsorbed on the suction cup while the mold is unloading. Loading and unloading are carried out simultaneously, saving time and improving production efficiency.

[0024] 3. By setting the pressure roller and the curved scraper, the swing arm swings, and the pressure roller can be driven to roll along the mold under the action of the first spring. The curved scraper can peel off the tape and expose the feed port through the action of the torsion spring. When the swing arm swings back, the pressure roller can stick the tape back to the mold. No manual operation is required, which is convenient and fast, saves manpower, and ensures operation quality.

[0025] 4. By setting up a turntable, the third electric push rod drives the turntable to rotate, and then the radial rod on the turntable drives all the swing rods and the second slide rod to swing, so that the mold can simultaneously remove the tape and stick the tape at the same time. In addition, a nozzle is provided above each mold to enable resin infusion to be carried out simultaneously. Six molds can be infused at the same time each time, which greatly improves the efficiency of resin infusion and is conducive to mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In the above S1 of this embodiment, when fixing the material box 13, the material box 13 is placed on the table 111, and the positioning pins 131 are inserted into the holes on the table 111 to complete the fixation; and the molds 7 in the material box 13 are all completed by sticking with tape, and the opening of the mold 7 is facing the direction of the nozzle 5 ( Figure 2 middle).

[0050] In the above S2 of this embodiment, when the grabbing assembly is working, the second motor 27 is started to drive the working block 31 to rotate clockwise ( Figure 1 3c and the second through hole 311 are connected to the first flow channel 235, so that the vacuum machine connected to the first flow channel 235 can work to generate vacuum. The source sucks away the air in the suction cup 33, and the mold 7 is sucked onto the suction cup 33. As the working block 31 rotates, the protruding rod 321 enters the arc groove 232, controlling the first slide bar 32 to contract, so that the first through hole 322 and the second through hole 311 are disconnected. Due to the effect of the sealing member on the first slide bar 32, the suction cup 33 maintains a vacuum, and the mold 7 can be sucked onto the suction cup 33 all the time. Through the continuous rotation of the working block 31, the first electric push rod 15 pushes the push plate 14 to make the mold 7 fill the position, so that all the suction cups 33 can suck the mold 7. When the working block 31 rotates to the position as shown in the figure, the first electric push rod 15 pushes the push plate 14 to make the mold 7 fill the position, so that all the suction cups 33 can suck the mold 7. Figure 9 When the position is shown, all the protruding rods 321 on the first slide rods 32 are located in the arc groove 232 (as shown in FIG. Figure 10 As shown), all the first slide bars 32 are retracted, and the mold 7 is adsorbed on all the suction cups 33, completing the loading of the mold 7.

[0051] In the above S3 of this embodiment, when the switching component is working, the first motor 26 is controlled to drive the shaft 22 to rotate. Since the first bevel gear 24 and the incomplete bevel gear 25 are engaged, the shaft 22 drives the connecting frame 23 to rotate when the connecting frame 23 rotates, thereby driving the working block 31 to rotate accordingly, so that the working block 31 is rotated to a horizontal state, and the side of the working block 31 connected to the second electric push rod 43 is facing upward. At this time, the nozzle 5 is located directly above the mold 7, and then the second electric push rod 43 is controlled to retract, driving the pressure roller 61 of the uncovering component to press on the mold 7 (as shown in FIG. Figure 7 to complete the working mode switching.

[0052] In the above S4 of this embodiment, when pouring resin into the mold 7, the third electric push rod 44 is controlled to extend, driving the turntable 42 to rotate. Since all the radial rods 421 slide in the grooves 631 respectively, the radial rods 421 drive the rocker rod 63 to swing. Under the action of the first spring 65, the second slide bar 64 drives the pressure roller 61 to roll along the mold 7. At the same time, under the action of the torsion spring 66, the arc scraper 62 slides along the outer edge of the mold 7 to scrape off the tape on the outside of the mold 7, and the tape is turned outward along the arc structure of the arc scraper 62. When the pressure roller 61 comes to the right side of the mold 7, the tape is peeled off, exposing the feed port of the mold 7, and resin is introduced into all the nozzles 5. The resin enters the mold 7 through the nozzles 5. When the resin is full, the third electric push rod 44 is controlled to retract, driving the pressure roller 61 to return, and then the tape is re-sticked by the action of the pressure roller 61 to complete the resin pouring.

[0053] In the above S5 of this embodiment, when the resin infusion is completed, the second electric push rod 43 is controlled to extend, so that the pressure roller 61 and the mold 7 are separated, and then the first motor 26 is controlled to reverse, driving the working block 31 to reset, and the second motor 27 is started to drive the working block 31 to continue to rotate clockwise, driving the protruding rod 321 to enter the connection between the second transition groove 233b and the connecting groove 234. At this time, the first slide bar 32 is vertically downward and extends downward, driving the mold 7 to come to the conveyor belt. At this time, the second through hole 311 is connected to the first through hole 322 in the first slide bar 32, and the second through hole 311 is connected to the second flow channel 236, so that the air Entering the suction cup 33, the suction cup 33 and the mold 7 after resin infusion are separated, and the mold 7 remains on the conveyor belt and is conveyed out of the equipment for subsequent processing. As the working block 31 rotates continuously, the mold 7 on all the suction cups 33 can be unloaded. And as the working block 31 rotates, when the protruding rod 321 enters the connection between the first transition groove 233a and the connecting groove 234 through the connecting groove 234, the first slide bar 32 performs the mold 7 loading action again, so that the working block 31 is controlled to rotate 360 degrees to unload the previous batch of molds 7 onto the conveyor belt, and at the same time, the next batch of molds 7 can be loaded onto all the suction cups 33.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
