Description

Technical Field

[0001] This invention relates to the field of lens assembly technology, and more particularly to a lens pre-assembly device with a peel-off film. Background Technology

[0002] VR glasses typically consist of a frame and lens assemblies. When materials arrive at the upstream equipment, the frame is placed in the first slot on the left side of the carrier, and the lens assembly is placed in the second slot on the right side. Upon arrival, the lens assembly includes a lens body and an adhesive film attached to the upper surface of the lens body. A protective film is also attached to the upper surface of the adhesive film. Generally, the edge of the protective film has an exposed portion protruding from the film, which production line workers can easily peel off by pinching the exposed portion. To attach the lens assembly to the frame, the protective film on the adhesive film must first be peeled off. Then, the lens body and adhesive film are inverted and placed into the mounting holes of the frame (at this point, the adhesive film has not yet been subjected to heat pressing, so its adhesion is not activated). Subsequently, heat pressing is performed to activate the adhesive film, allowing the lens body to be securely attached to the frame. Currently, there is no mechanical equipment for pre-installing the lens assembly by peeling off the protective film; the pre-installation of the lens assembly and frame must be done manually, resulting in low work efficiency.

[0003] Therefore, it is necessary to develop a lens film peeling and pre-assembly equipment to realize the mechanized operation of lens assembly film peeling and pre-assembly, thereby reducing labor costs and improving production efficiency.

[0004] 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

[0068] It should be noted that each of the linear drive mechanisms can be a telescopic cylinder, a rodless cylinder, or a motor lead screw assembly, etc., and each of the rotary drive mechanisms can be a servo motor or a rotary cylinder, etc., and the gripper assembly 501 can be a gripper cylinder or a hydraulic gripper, etc. The specific structure of the linear drive mechanism, the rotary drive mechanism, and the gripper assembly 501 is not the focus of this invention, so it will not be described in detail.

[0069] The lens coating pre-installation device provided in this embodiment operates as follows:

[0070] S10: At the start, the conveyor 1 sends the vehicle 8 from upstream;

[0071] It should be noted that at this time, the frame is placed in the first slot on the left side of the carrier 8, and the lens assembly is placed in the second slot on the right side of the carrier 8; the lens assembly includes a lens body and a film pasted on the upper surface of the lens body. A protective film is also attached to the upper surface of the film, and the edge of the protective film has an exposed part that protrudes from the film.

[0072] S20: The first linear drive mechanism 202, the second linear drive mechanism 203 and the third linear drive mechanism 204 cooperate to drive the first suction head 201 to pick up the lens assembly from the carrier 8 and then place the lens assembly into the transfer platform 3.

[0073] It should be noted that when the lens assembly is located on the transfer platform 3, the protective film is on top.

[0074] S30: The first rotary drive mechanism 402 rotates in the forward direction, driving the second suction head 401 to rotate toward the transfer platform 3, and the second suction head 401 sucks up the lens assembly; specifically, the second suction head 401 sucks up the protective film located at the top.

[0075] S40: The first rotary drive mechanism 402 rotates in the opposite direction, driving the second suction head 401 to rotate 180°. At this time, the second suction head 401 and the lens assembly will both flip up and down.

[0076] Specifically, at this time, the lens assembly is located above the second suction head 401, and the lens assembly consists of the lens body, film and protective film from top to bottom; that is, the protective film has been moved to the bottom.

[0077] S50: The first linear drive mechanism 202, the second linear drive mechanism 203 and the third linear drive mechanism 204 cooperate to drive the first suction head 201 to suck up the lens assembly from top to bottom (specifically, the lens body is sucked up by the first suction head 201), and the second suction head 401 releases the lens assembly (specifically, the second suction head 401 releases the protective film); then, the first transfer mechanism 2 moves the lens assembly to a position close to the clamping mechanism 5;

[0078] S60: The gripper assembly 501 closes and holds the exposed part of the protective film; the first linear drive mechanism 202, the second linear drive mechanism 203 and the third linear drive mechanism 204 cooperate to drive the first suction head 201 to put the lens assembly back into the carrier 8.

[0079] It should be noted that, since the protective film is held by the gripper assembly 501, when the first transfer mechanism 2 moves the lens assembly away from the film clamping mechanism 5, the protective film will remain on the gripper assembly 501, thereby completing the film peeling operation.

[0080] S70: The gripper assembly 501 opens, and the air supply pipe 503 blows out plasma air to prevent the protective film from adhering to the gripper assembly due to static electricity. Under the action of plasma air, the protective film is blown into the collection frame 502, effectively preventing the problem of the torn protective film scattering everywhere.

[0081] S80: The conveyor 1 transports the carrier 8 downwards to a position close to the second transfer mechanism 7:

[0082] S801: The fourth linear drive mechanism 702, the sixth linear drive mechanism 705 and the seventh linear drive mechanism 706 work together to transfer the frame from the carrier 8 to the fixture body 601.

[0083] S802: First, the fifth linear drive mechanism 704, the sixth linear drive mechanism 705 and the seventh linear drive mechanism 706 work together to transfer the lens assembly from the carrier 8 to the top of the jig body 601.

[0084] Next, the second rotary drive mechanism 602 and the third rotary drive mechanism 603 work together to rotate the fixture body 601 up, down, left and right, adjusting the angle of the fixture body 601 so that the frame is in a position that facilitates the entry and exit of the lens assembly.

[0085] Finally, the fifth linear drive mechanism 704 extends and inserts the lens assembly downward into the mounting hole of the frame;

[0086] S803: The fourth linear drive mechanism 702, the sixth linear drive mechanism 705 and the seventh linear drive mechanism 706 work together to move the frame from the jig body 601 back to the carrier 8.

[0087] It should be noted that at this time, the eyeglass frame is placed in the first slot on the left side of the carrier 8, and the lens assembly is placed in the mounting hole of the eyeglass frame. The second slot on the right side of the carrier 8 is empty.

[0088] S90: The conveying device 1 sends the carrier 8 into the downstream hot pressing equipment to hot press the pre-assembled lens assembly and activate the adhesiveness of the film.

[0089] 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.

[0090] 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.
