[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 6As shown, this embodiment provides an automatic adhesive bonding device for sapphire lenses, including a base 1, a material tray 2, a feeding mechanism 3, a lens clamping station 4, an adhesive positioning station 5, an adhesive feeding mechanism 6, an unloading station 7, an adsorption and movement mechanism 8, and an unloading mechanism 9. The base 1 is provided with a base plate 11. The lens clamping station 4, the adhesive positioning station 5, and the unloading station 7 are sequentially arranged along the extending direction of the base plate 11. The material tray 2 is disposed on the base 1 at the side end of the lens clamping station 4 and is used to hold sapphire lenses. The feeding mechanism 3 is disposed between the material tray 2 and the lens clamping station 4. The feeding mechanism 3 is used to adsorb and transfer the sapphire lens on the material tray 2 to the lens clamping station 4. The adhesive feeding mechanism 6 is located at the side of the adhesive positioning station 5 and is used to provide adhesive to the adhesive positioning station 5. The adsorption and moving mechanism 8 is located above the base plate 11 and is used to adsorb and transfer the sapphire lens located on the lens clamping station 4, the adhesive positioning station 5, and the unloading station 7. The unloading mechanism 9 is located above the unloading station 7 and is used to adsorb and unload the sapphire lens that has been coated on the unloading station 7. The feeding mechanism 3 can remove the sapphire lens from the material tray 2 and transfer it to the lens clamping station 4. The lens clamping station 4 is used to stabilize and adjust the position of the sapphire lens, thus preparing for the subsequent adhesive bonding operation. Subsequently, the adhesive feeding mechanism 6 can convey the adhesive to the adhesive positioning station 5 and complete the precise positioning of the adhesive, effectively improving the bonding accuracy between the sapphire lens and the adhesive. At the same time, the adsorption and movement mechanism 8 can adsorb and move the sapphire lens from the clamping station to the adhesive positioning station 5, thereby realizing the adhesive bonding operation. After the bonding is completed, the sapphire lens is immediately transferred by the adsorption and movement mechanism 8 to the unloading station 7, and the unloading mechanism 9 completes the adsorption and unloading operation. The whole process is automated, with high adhesive bonding accuracy, thereby improving the adhesive bonding effect of the sapphire lens.

[0038] like Figures 1 to 3 As shown, the lens clamping station 4 further includes a finger cylinder 41, a lens clamping block 42, and a lens adsorption plate 43. Multiple finger cylinders 41 are spaced apart along the extension direction of the base plate 11. The two movable ends of each finger cylinder 41 are connected to the lens clamping block 42 to drive the two lens clamping blocks 42 to move closer together or apart. The lens adsorption plate 43 is located between the two lens clamping blocks 42 and is used to adsorb sapphire lenses. When the loading mechanism 3 transfers the sapphire lens to the lens clamping station 4, the finger cylinder 41 can drive the lens clamping block 42 to move towards or separate from the center of the lens, allowing the lens clamping block 42 to clamp or release the lens, preventing the sapphire lens from sliding or shifting, and keeping the sapphire lens in a specific attachment position for subsequent adhesive application.

[0039] like Figure 6 As shown, the adhesive positioning station 5 further includes a position adjustment component 51 and an adhesive adsorption plate 52. The adhesive adsorption plate 52 is located on top of the position adjustment component 51, and a positioning rod 521 is provided on the adhesive adsorption plate 52. The positioning rod 521 is adapted to and connected to the positioning hole on the adhesive. The position adjustment component 51 is used to adjust the lateral and longitudinal positions of the adhesive adsorption plate 52. During the adhesive application process, the adhesive feeding mechanism 6 can deliver the adhesive to the position of the adhesive adsorption plate 52. The adhesive adsorption plate 52 can stably absorb the adhesive through adsorption and, through the positioning rod 521 inserted into the positioning hole on the adhesive, achieve the limiting effect on the adhesive and prevent displacement during the adhesive application process. Since different types of adhesives have different errors during the alignment process, the position adjustment component 51 can adjust the lateral and longitudinal directions of the adhesive to ensure that the adhesive application position is accurately aligned with the bonding area of ​​the sapphire lens.

[0040] like Figure 4 and Figure 5 As shown, the adhesive feeding mechanism 6 further includes a linear cylinder 61, a first lifting cylinder 62, and an adhesive placement plate 63. The linear cylinder 61 is located on the side of the base plate 11. The movable end of the linear cylinder 61 is connected to the first lifting cylinder 62 through a connecting plate. The movable end of the first lifting cylinder 62 is set downward and connected to the adhesive placement plate 63. The adhesive placement plate 63 is provided with a plurality of positioning grooves 630 for placing adhesive. When the adhesive needs to be transferred to the adhesive positioning station 5, the linear cylinder 61 is activated, driving the first lifting cylinder 62 connected to it to move forward synchronously through the connecting plate. Then, the movable end of the first lifting cylinder 62 moves downward to lower the adhesive placement plate 63 above the adhesive adsorption plate 52. Finally, the adsorption moving mechanism 8 can adsorb the top layer of adhesive on the adhesive placement plate 63. The linear cylinder 61 pushes the adhesive placement plate 63 back, and the adhesive adsorbed by the adsorption moving mechanism 8 is placed on the adhesive adsorption plate 52, thus completing the single-piece feeding of the adhesive.

[0041] like Figure 2As shown, the adsorption and movement mechanism 8 further includes a gantry frame 81, a linear movement module 82, a moving plate 83, a second lifting cylinder 84, and a first suction nozzle 85. The gantry frame 81 is located above the base plate 11, and the linear movement module 82 is located on the gantry frame 81. The movable end of the linear movement module 82 is connected to the moving plate 83. Several second lifting cylinders 84 are spaced apart on the moving plate 83, with the movable ends of the second lifting cylinders 84 facing downwards and connected to the first suction nozzle 85. After the sapphire lens is clamped or attached, the first suction nozzle 85 moves downwards under the drive of the second lifting cylinder 84, adsorbs the sapphire lens, and then rises. The moving module drives the moving plate 83 to move laterally, thereby transferring the sapphire lens sequentially to the adhesive positioning station 5 for pressing and applying adhesive or to the unloading station 7.

[0042] like Figure 2 As shown, the unloading station 7 further includes a column 71 and a second suction nozzle 72. A plurality of columns 71 are spaced apart along the extension direction of the base plate 11. The second suction nozzle 72 is located on the top of the column 71 and is used to adsorb the sapphire lens after the adhesive backing has been applied.

[0043] like Figure 2 As shown, it further includes a plasma air gun 70, which is located at the side of the unloading station 7. The plasma air gun 70 is used to blow plasma air upwards. When the sapphire lens on the unloading station 7 is adsorbed and transferred under the action of the unloading mechanism 9, the plasma air gun 70 can blow plasma air upwards to clean the adhesive surface of the sapphire lens, thereby removing surface impurities and eliminating static electricity.

[0044] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
