Description

Technical Field

[0001] This invention relates to the field of lens assembly technology, and more particularly to a lens adhesive feeding device. Background Technology

[0002] With the development of technology, VR glasses are becoming increasingly popular. VR glasses typically consist of a frame and lenses; specifically, the lenses are glued to the frame using film. To improve the production efficiency of VR glasses, a VR glasses assembly line has been developed to achieve mechanized assembly of the lenses and frames.

[0003] However, the lenses and film arrive independently; that is, the film is not adhered to the lens (it should be noted that the film has protective films on both the top and bottom surfaces upon arrival, and these films need to be removed before use). Currently, the film is mainly pasted onto the lenses manually, resulting in low production efficiency.

[0004] Therefore, it is necessary to develop a lens adhesive feeding device for VR glasses assembly lines, which can mechanically supply lenses with pre-applied adhesive to VR glasses assembly lines, thereby improving production efficiency.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0065] This invention provides a lens adhesive feeding device, suitable for applications where adhesive film is pasted onto lenses, and then the frame and the lens with the adhesive film are sent together to downstream equipment for assembly. This invention uses a transfer component to paste the adhesive film onto the lens, and then places the lens into a carrier. A second conveying device then sends the carrier containing the frame and the lens with the adhesive film to the downstream equipment.

[0078] Optionally, both the first conveying device 2 and the second conveying device 4 can be conveyor belts or feeding roller groups. Furthermore, the first conveying device 2 and the second conveying device 4 are arranged in parallel, and their feeding directions are opposite.

[0079] In this embodiment, the transverse mechanism 3 includes a first conveyor belt 301, a first rotary drive mechanism 302 that can drive the first conveyor belt 301 to rotate in both directions, and a first linear drive mechanism 303; further, the first linear drive mechanism 303 drives the first conveyor belt 301 to reciprocate between the first conveying device 2 and the second conveying device 4.

[0080] See Figure 3The lens feeder 5 includes a housing 501, a triangular top block 502, a compression spring, a lifting platform 503, a second conveyor belt 504, and a second linear drive mechanism 505. The chassis 501 includes a storage space 5011, and an mounting block 5012 on the upper part of the side wall of the chassis 501. The mounting block 5012 has a mounting groove with an opening facing the storage space 5011. The lower part of the triangular apex block 502 is hinged to the mounting groove via a pivot. A compression spring is located between the upper part of the triangular apex block 502 and the mounting block 5012, and is used to drive the upper part of the triangular apex block 502 to rotate into the storage space 5011. A lifting platform 503 is located in the storage space 5011 and is used to push several stacked lens trays 13 upwards above the triangular apex block 502. It is also used to transport the lens trays 13 from the chassis 501 to the transfer mechanism 7. The driving end of the second linear drive mechanism 505 is connected to the mounting block 5012 and is used to drive the mounting block 5012 to move up and down.

[0081] The film feeder 6 includes a film tray 601 and a third linear drive mechanism 602. The film tray 601 has a plurality of film slots for placing film, and each film slot has an air suction hole at its bottom. The drive end of the third linear drive mechanism 602 is connected to the film tray 601, driving the film tray 601 to move closer to or away from the transfer mechanism 7.

[0082] Optionally, the transfer mechanism 7 is a four-axis or six-axis robotic arm. Furthermore, the transfer mechanism 7 is also equipped with a camera assembly; when the camera assembly detects defects in the lens or film, the transfer mechanism 7 directly sends the defective material into the waste rack 14.

[0083] The transfer mechanism 8 includes a heating platform 801 and a fourth linear drive mechanism 802. The heating platform 801 is provided with a positioning groove; the drive end of the fourth linear drive mechanism 802 is connected to the heating platform 801, driving the heating platform 801 to reciprocate between the transfer mechanism 7 and the pre-pressing mechanism 11.

[0084] The positioning component 9 is located between the transfer mechanism 7 and the pre-pressing mechanism 11. The positioning component 9 includes a positioning block 901 and a fifth linear drive mechanism 902. The shape of the positioning block 901 matches the positioning groove. The driving end of the fifth linear drive mechanism 902 is connected to the positioning block 901 and is used to drive the positioning block 901 to move up and down.

[0085] The plasma cleaner 10 is installed on the working platform 1, located between the transfer mechanism 7 and the pre-pressure mechanism 11, and is used to perform plasma cleaning on the lenses. Its specific structure is not the focus of this invention, so it will not be described in detail.

[0086] The pre-compression mechanism 11 includes a pre-compression suction head 1101, a sixth linear drive mechanism 1102, and a seventh linear drive mechanism 1103. The shape of the pre-compression suction head 1101 matches the film; the drive end of the sixth linear drive mechanism 1102 is connected to the pre-compression suction head 1101 and is used to drive the pre-compression suction head 1101 to move up and down; the drive end of the seventh linear drive mechanism 1103 is connected to the sixth linear drive mechanism 1102 and is used to drive the pre-compression suction head 1101 to reciprocate between the carrier 12 and the transfer mechanism 8.

[0087] It should be noted that each of the linear drive mechanisms can be a telescopic cylinder, a rodless cylinder, or a motor lead screw slider assembly, etc., and each of the rotary drive mechanisms can be a motor or a rotary cylinder, etc., and the present invention does not limit them.

[0088] The lens adhesive feeding device provided in this embodiment operates as follows:

[0089] S10: At the start, the status of each loading station is as follows:

[0090] S101: The production line worker stands in front of the frame loading station (i.e., next to the lens loading station), and the first conveyor belt 301 is aligned with the first conveyor device 2.

[0091] S102: The lifting platform 503 lifts the stacked lens trays 13 on the lifting platform 503 until the bottom lens tray 13 is higher than the triangular top block 502, then the lifting platform 503 returns to its original position.

[0092] It should be noted that triangular apex blocks 502 are provided on both the left and right sides of the chassis 501. The width of the lens tray 13 is slightly larger than the distance between the two oppositely arranged triangular apex blocks 502. Therefore, the up and down movement of the lens tray 13 is affected by the triangular apex blocks 502.

[0093] The width of the lifting platform 503 is smaller than the distance between the two oppositely arranged triangular top blocks 502. Therefore, the vertical movement of the lifting platform 503 is not affected by the triangular top blocks 502.

[0094] In this embodiment, the inclined surface of the triangular top block 502 faces downward. During the process of the lifting platform 503 rising, when the lens tray 13 contacts the inclined surface of the triangular top block 502, the lens tray 13 overcomes the elastic force of the compression spring and drives the upper end of the triangular top block 502 to rotate upward, so that the triangular top block 502 is completely inserted into the mounting groove and will not hinder the upward movement of the lens tray 13.

[0095] When the bottom lens tray 13 moves upward to above the triangular top block 502, the compression spring drives the triangular top block 502 to rotate toward the storage space 5011. The upper part of the triangular top block 502 extends back into the storage space 5011. Therefore, when the lifting platform 503 moves downward, each lens tray 13 will be blocked by the triangular top block 502 and cannot move downward.

[0096] S103: The production line worker places the top lens tray 13 on the second conveyor belt 504, and the second conveyor belt 504 transports the lens tray 13 to a position close to the transfer mechanism 7.

[0097] Subsequently, whenever a production line worker takes away a lens tray 13, the second linear drive mechanism 505 drives the three top blocks to rise one level so that the production line worker can take the lens tray 13 again.

[0098] S104: The upstream equipment places the film with protective film on both the upper and lower surfaces into the film tray 601, and the third linear drive mechanism 602 drives the film tray 601 to move to a position close to the transfer mechanism 7.

[0099] S20: The first conveying device 2 delivers an empty carrier 12 from a location far from the frame loading station to the frame loading station; wherein, the carrier 12 has a slot for placing the frame and several slots for placing the lens.

[0100] At this time, the first rotary drive mechanism 302 drives the first conveyor belt 301 to rotate in the forward direction, so that the first conveyor belt 301 rotates in the same direction as the first conveyor device 2, so the empty vehicle 12 will fall onto the first conveyor belt 301.

[0101] Next, the production line worker places a picture frame into the slot in carrier 12 for placing picture frames;

[0102] Then, the first linear drive mechanism 303 drives the first conveyor belt 301 to move laterally until it is aligned with the second conveyor device 4;

[0103] Subsequently, the first rotary drive mechanism 302 drives the first conveyor belt 301 to rotate in the opposite direction, so that the first conveyor belt 301 rotates in the same direction as the second conveyor device 4, so that the carrier 12 carrying the picture frame will enter the second conveyor device 4.

[0104] Finally, the second conveying device 4 transports the carrier 12 carrying the picture frame downwards to the area below the pre-compression mechanism 11;

[0105] S30: The transfer mechanism 7 takes out the lens from the lens tray 13 and places it on the positioning groove of the heating platform 801;

[0106] Next, the fourth linear drive mechanism 802 drives the heating platform 801 to move directly below the positioning block 901, and the fifth linear drive mechanism 902 drives the positioning block 901 to press the lens down to prevent the lens from being misplaced and affecting subsequent adhesive application and pre-pressing.

[0107] S40: The fourth linear drive mechanism 802 drives the heating platform 801 to move directly below the plasma cleaner 10, and the plasma cleaner 10 performs plasma cleaning on the lens.

[0108] S50: The fourth linear drive mechanism 802 drives the heating platform 801 to move back to a position close to the transfer mechanism 7. The transfer mechanism 7 removes the film from the film tray 601 and places the film on the lens on the heating platform 801.

[0109] It should be noted that the air inlet at the bottom of the film acupoint will suck up the protective film at the bottom of the film. Therefore, when the transfer mechanism 7 picks up the film, the film is removed from the film acupoint at the same time, and the film removal operation at the bottom is completed simultaneously.

[0110] S60: The fourth linear drive mechanism 802 drives the heating platform 801 to move directly below the seventh linear drive mechanism 1103, and the heating platform 801 starts the heating function to activate the film.

[0111] The seventh linear drive mechanism 1103 laterally adjusts the position of the pre-pressure suction head 1101 so that the pre-pressure suction head 1101 is aligned with the film;

[0112] The sixth linear drive mechanism 1102 drives the pre-pressure suction head 1101 to press the film and lens downwards; after a period of time (e.g., 3s or 5s), the sixth linear drive mechanism 1102 retracts upwards to complete the bonding operation of the lens and film.

[0113] S70: The seventh linear drive mechanism 1103 adjusts the position of the pre-pressure suction head 1101 laterally so that the film held by the pre-pressure suction head 1101 is aligned with the slot of the carrier 12 for placing the lens.

[0114] The sixth linear drive mechanism 1102 drives the pre-press suction head 1101 to move downward and release the film and lens, thereby placing the lens with the film attached into the carrier 12;

[0115] S80: The second conveying device 4 transports the carrier 12, which carries the frame and the lens with film attached, to the downstream equipment.

[0116] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0117] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
