Technical Field

[0001] The invention relates to the technical field of optical lens production, in particular to an automatic optical component gluing machine. Background Art

[0002] Optical lenses are lenses made of optical glass. The definition of optical glass is glass with specific requirements for optical properties such as refractive index, dispersion, transmittance, spectral transmittance and light absorption, and with uniform optical properties. Glass that can change the propagation direction of light and the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass in a narrow sense refers to colorless optical glass: optical glass in a broad sense also includes colored optical glass, laser glass, quartz optical glass, radiation-resistant glass, ultraviolet infrared optical glass, dimensional optical glass, acousto-optic glass, magneto-optical glass and photochromic glass. Optical glass can be used to manufacture lenses, prisms, reflectors and windows in optical instruments. In the production process of optical lenses, optical lenses need to be glued.

[0003] During the production process of glued lenses, they will be divided into two parts, one of which is the lens to be glued, and the other is the lens to be glued. It is necessary to first apply glue on the upper surface of the glued lens and then press the lens to be glued onto the lens to be glued. Wait for the glue to solidify and the process is complete.

[0004] Due to the high precision requirements of optical lenses, the dispensing and pressing equipment currently used are generally performed independently. There is a long time interval between the completion of lens dispensing and pressing. The glue may be slightly solidified during the waiting time, resulting in unsatisfactory gluing effect after subsequent pressing, increasing the defective rate and relatively low gluing efficiency.

[0008] The lens gluing table is also provided with a glue dispensing mechanism located above the lens placement groove, and the glue dispensing mechanism is used for dispensing glue on the upper surface of the lens to be glued.

DETAILED DESCRIPTION

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0029] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the optical component automatic gluing machine designed by the present invention comprises a lens feeding line 1, a lens unloading line 2 and a lens gluing table 3 arranged between the lens feeding line 1 and the lens unloading line 2; the lens feeding line 1 is used for continuously and cross-intervally conveying lenses to be dispensed and lenses to be glued;

[0030] The lens gluing platform 3 is provided with a lens fixing seat 4, and the lens fixing seat 4 is provided with a lens placement groove 4.1 in the vertical direction; the lens gluing platform 3 is provided with a transfer frame 5 and a transfer mechanism connected to the transfer frame 5 along one side of the lens fixing seat 4; the transfer frame 5 is provided with a lens clamping mechanism and a lens pressing mechanism in sequence, and the transfer mechanism is used to drive the transfer frame 5 to move, so that the lens clamping mechanism sequentially installs the lens to be dispensed and the lens to be glued from the loading line 1 to the lens placement groove 4.1 or extracts the glued lens from the lens placement groove 4.1 to the lens unloading line 2, and the lens pressing mechanism presses the lens to be dispensed and the lens to be glued in the lens placement groove 4.1;

[0031] The lens gluing platform 3 is also provided with a glue dispensing mechanism located above the lens placement groove 4.1, and the glue dispensing mechanism is used for dispensing glue on the upper surface of the lens to be glued.

[0032] In the present embodiment, after the lens to be glued is clamped by the lens clamping mechanism and loaded into the lens placement groove 4.1 of the lens fixing seat 4, glue is applied to the upper surface of the lens to be glued by the glue dispensing mechanism, and then the subsequent lens to be glued is clamped by the lens clamping mechanism and placed on the upper part of the lens to be glued; then, the lens to be glued and the lens to be glued are pressed by the lens pressing mechanism; after the glue is initially solidified, the glued lens is clamped by the lens clamping mechanism and transported to the lens unloading line 2 for unloading and transportation, which greatly reduces the time interval between the two processes of glue dispensing and pressing, ensures the viscosity of the glue, and improves the gluing effect; at the same time, the continuity of lens transportation, glue dispensing and pressing is higher, ensuring production efficiency.

[0033] As an embodiment, the transfer mechanism includes a transfer frame horizontal moving assembly 6 for adjusting the horizontal position of the transfer frame, and a transfer frame vertical moving assembly 7 for adjusting the vertical position of the transfer frame, which can accurately adjust the position of the transfer frame 5 to achieve the lens clamping mechanism and the lens pressing mechanism to accurately grasp the lens and the lens pressing process. The transfer frame horizontal moving assembly 6 and the transfer frame vertical moving assembly 7 can use linear electric guide rail drivers.

[0034] As an embodiment, the lens clamping mechanism includes two sets of lens clamping tools 8 arranged opposite to each other, and a first driving cylinder 9 drivingly connected to the lens clamping tools 8, wherein the first driving cylinder 9 can drive the two sets of lens clamping tools 8 to move closer to each other to clamp the lens. The two sets of lens clamping tools 8 are formed with arc-shaped clamping grooves adapted to the lens on opposite sides.

[0035] As an embodiment, the lens pressing mechanism includes a lens pressing plate 10 and a pressing cylinder 11 connected to the lens pressing plate 10. The pressing cylinder 11 presses the pressing plate 10 to provide a stable pressing force to the glue-dispensing lens and the lens to be glued, thereby ensuring the bonding strength between the lens to be glued and the lens to be glued after the glue is cured.

[0036] Specifically, the lens pressing mechanism further includes two groups of lens positioning tools 12 arranged opposite to each other, and a second driving cylinder 13 drivingly connected to the lens positioning tools 12, and the second driving cylinder 13 can drive the two groups of lens positioning tools 12 to approach each other to position the lens to be glued and the lens to be glued. The two groups of lens positioning tools 12 are formed with arc-shaped clamping grooves adapted to the lenses on the opposite sides. When the lens to be glued is placed on the lens to be glued, the second driving cylinder 13 can drive the two groups of lens positioning tools 12 to clamp the lens to be glued and the lens to be glued laterally at the same time, so as to ensure that the optical axes of the lens to be glued and the lens to be glued are consistent, and avoid deviation after gluing.

[0037] The depth of the lens placement groove 4.1 can be less than the thickness of the lens to be glued, so as to ensure that the upper part of the lens to be glued is exposed after being placed, so as to facilitate positioning with the lens to be glued.

[0038] As an embodiment, the lens placement groove 4.1 is further provided with a re-pressing plate 14 for supporting the lower surface of the lens to be glued, and a re-pressing plate pressing cylinder 15 connected to the re-pressing plate 14. When the lens to be glued and the lens to be glued are pressed together, the lens pressing plate 10 can be pressed from top to bottom, and then the re-pressing plate pressing cylinder 15 drives the re-pressing plate 14 to perform secondary re-pressing vertically upwards to ensure tighter gluing.

[0039] After the lenses are initially glued, the lens pressing plate 10 returns to its original position, and the re-pressing plate 14 continues to move upward to push out the glued lenses, so that the lens clamping mechanism can grab them.

[0040] As an implementation mode, the glue dispensing mechanism includes a lifting frame 16 and a lifting assembly 17 connected to the lifting frame 16; a glue dispensing head 18 is mounted on the lifting frame 16, and the lifting frame 16 can be lifted and lowered under the drive of the lifting assembly 17 to drive the glue dispensing head 18 to approach the lens to complete glue dispensing. The lifting assembly 17 can be a cylinder lifting component or a hydraulic lifting component.

[0041] As an embodiment, a curing hood 19 is provided above the lens unloading line 2, and a plurality of curing light groups 20 are arranged in sequence on the curing hood 19 along the conveying direction of the lens unloading line 2. When the lenses that have undergone preliminary curing are conveyed via the lens unloading line 2, they can be further cured under the irradiation of the curing light groups 20. For example, the UV glue used for gluing can be irradiated with ultraviolet rays to generate active free radicals or ion radicals, thereby initiating polymerization, cross-linking and grafting reactions, so that the glue is fully cured.
