Description

Technical Field

[0001] This utility model belongs to the field of lens manufacturing technology, and in particular relates to an integrated device for mold making and glue injection of spectacle lenses. Background Technology

[0002] In the manufacturing process of eyeglass lenses, the mold assembly and glue injection are integrated. This involves overlapping two circular molds, A and B, at a certain interval, using transparent tape to bond the radial ends together, and then injecting the glue. Currently, eyeglass lens manufacturing separates mold assembly and glue injection. After mold assembly, the parts are transferred to the glue injection station. Before injection, the pre-assembled tape needs to be torn open slightly, and then the glue is applied again. This requires two rolls of tape. Existing technology makes the glue injection process cumbersome and complex, with most injections performed manually. Separating the two processes leads to repetitive steps with uncontrolled precision, and the process switching and transfer is time-consuming, labor-intensive, and space-consuming.

The mold rotation module adsorbs and positions two molds at a distance. The glue delivery module stores and lowers the tape to the joint of the two molds. The rotation of the mold rotation module causes the tape to wrap around the joint of the two molds once, and the tape fixing and sealing module presses it tightly. Before the tape is fully wrapped and sealed, the glue injection mechanism of the glue delivery module injects glue between the two molds. Then, the tape cutting module cuts the tape, and the tape fixing and sealing module seals the ends of the tape to complete the integrated molding and glue injection operation.

Then, the tape cutting module 440 cuts the tape 421, and the tape fixing and sealing module 300 glues the ends of the tape 421 together to complete the integrated mold-fitting and glue-injection operation.

[0024] It should be noted that the mold rotation module 200 uses vacuum suction to adjust the mold spacing and make it rotate; the glue feeding module 400 uses a cylinder to feed and cut the tape, and uses a motor to adjust the position so that the glue injection port can be aligned with the mold; the tape fixing and sealing module 300 is used to adjust the shape of the transparent tape during the wrapping and glue injection process.

[0027] In a preferred embodiment, a mold suction cup 224 is installed at the end of the mold rotating spindle 223, and the mold suction cup 224 is connected to the vacuum generating device 225.

[0028] In a preferred embodiment, the glue feeding module 400 includes a glue feeding frame 410, on which a tape module 420, a glue dispensing module 450 and a tape cutting module 440 are mounted. The tape module 420 is used to store tape 421.

[0029] It should be noted that the tape cutting module 440 includes a cutting blade, which achieves the effect of cutting the tape 421 during the extension process through a telescopic power device.

[0030] In a preferred embodiment, the glue injection module 450 includes a glue injection frame 451, with a glue injection head 452 installed at the bottom of the glue injection frame 451. The glue injection frame 451 can move horizontally and lift vertically through a glue injection moving and lifting module 454.

[0031] In a preferred embodiment, a visual monitoring mechanism 453 is provided on one side of the dispensing head 452.

[0032] In a preferred embodiment, the tape fixing and sealing module 300 includes a sealing frame 350, on which a closing module 310, a top adhesive wheel 330, and a center distance measuring mechanism 340 are provided.

[0033] In a preferred embodiment, the closing module 310 is raised and lowered via the closing module lifting mechanism 320.

[0034] It should be noted that the closing module 310 includes a closing pressure plate, which is mounted on a telescopic cylinder. During the telescopic process, the closing pressure plate tightens the tape 421. The rear of the top adhesive wheel 330 and the center distance measuring mechanism 340 are both equipped with telescopic power devices.

[0035] Brief description of working principle:

[0036] The A-mold rotating module 210 and the B-mold rotating module 220 use a vacuum generator 225 to adsorb the corresponding lens molds. The center distance of the mold suction cups 224 is adjusted by the horizontal moving structure 222 of the base. At this time, the cylinder of the center distance measuring mechanism 340 is pushed out, the distance sensor measures the center distance and then retracts. The main shafts of the A-mold rotating module 210 and the B-mold rotating module 220 start to fine-tune the distance size and then wait.

[0037] Then, the lifting cylinder of the tape module 420 lifts and lowers the transparent tape 421 to the junction of the two molds. The telescopic cylinder of the top rubber roller 17 pushes out to bond the tape 421 to the radial end face of the mold. At this time, the rotating module 210 of mold A and the rotating module 220 of mold B start to rotate in the same direction, so that the tape 421 wraps around molds A and B. At the same time, the lifting cylinder 320 of the closing module 310 is activated, and the cylinder of the closing module 310 pushes out, so that the closing pressure plate leaves a gap at the top of molds A and B.

[0038] Then, the glue injection moving and lifting module 454 aligns the glue injection head 452 with the top gap of the mold and begins glue injection. The glue injection amount is monitored by the vision mechanism 453. After the glue injection is completed, the glue injection moving and lifting module 454 adjusts its position to a safe position. The main shafts of the A mold rotating module 210 and the B mold rotating module 220 start to rotate. The cylinder of the top glue wheel 330 retracts, the blade of the cutting module 440 extends, and the cylinder of the tape folding module 430 pushes out, thereby cutting and folding the transparent tape 421. The rotation of the A mold main shaft and the B mold main shaft wraps the remaining tail end around the mold, thus completing the process.
