An ultra-small lens carrier tray

Abstract

This utility model discloses an ultra-miniature lens carrier tray, comprising upper and lower trays and an elastic membrane sandwiched between them. The lower tray has an array of grooves on its surface, and the upper tray has protrusions corresponding to the grooves. Each protrusion has a through hole, through which a lens can be inserted and supported by the elastic membrane. The protrusions partially press the elastic membrane into the grooves, and the elastic membrane has a pre-stretch rate of 1% to 3% in the pressed area to eliminate air pockets and enhance the adhesion stability of the lens's bottom surface. The depth of the through hole is 0.45 to 0.60 times the height of the supported lens, thereby ensuring stable storage and easy removal of the lens. Preferably, the opposite surfaces of the grooves and protrusions have rounded chamfers, the lower tray has vent holes communicating with the grooves, and the surfaces of both trays are finely sanded to increase friction. The elastic membrane sandwiched between the upper and lower trays prevents warping or detachment due to long-term use. This tray effectively prevents ultra-miniature lenses from tipping over or scattering during handling, improving storage stability and reliability.

Description

Technical Field

[0001] This utility model relates to the field of ultra-small lens carrier technology, and in particular to an ultra-small lens carrier tray. Background Technology

[0002] In the processing, handling, and inspection of ultra-miniature optical lenses or prism particles, the extremely small size of the lenses (typically only 2-3 mm square) poses a high risk of tipping over during storage and handling on pallets. Current technology typically involves applying a blue film to the pallet surface and placing the lens on top, relying on the slight adhesiveness of the film to prevent tipping during transport. However, this method has the following problems: Firstly, the blue film, when flat against the pallet surface, is prone to air gaps or localized bulges, leading to insufficient lens stability. Secondly, the blue film, if left attached to the pallet surface for a long time, may detach due to aging, edge warping, or external interference, leaving the lenses within the pallet at risk of sliding or scattering during transport. Furthermore, as the number of lenses on the pallet increases, the manual application and placement of the film becomes more difficult, and factors such as vibration and tilting during transport further increase the probability of lens tipping.

[0003] Therefore, how to improve the reliability and service life of tray operation while ensuring the stable storage of ultra-small lenses has become a technical problem that needs to be solved in this field. Utility Model Content

[0004] The technical problem solved by this invention is that lenses are easily tipped over during the traditional tray handling process due to factors such as vibration and tilting.

[0005] To solve the above-mentioned technical problems, the present invention provides an ultra-miniature lens carrier tray, comprising:

[0006] The lower tray has grooves arranged in an array on its surface;

[0007] The upper tray is provided with a protrusion corresponding to the groove;

[0008] An elastic membrane is sandwiched between the upper tray and the lower tray, and the protrusion partially presses the elastic membrane into the groove; wherein

[0009] The protrusion is provided with a through hole, and a lens receiving groove is formed between the through hole and the elastic membrane;

[0010] The elastic membrane has a pre-stretch rate of 1% to 3% in the pressing area between the upper tray and the lower tray to eliminate voids and enhance the adhesion stability of the lens bottom surface.

[0011] The depth of the through hole is 0.45 to 0.60 times the height of the supported lens.

[0012] Optionally, both the protrusion and the groove have rounded chamfers on their opposite facing surfaces to prevent cutting or damaging the film edges.

[0013] Optionally, the surfaces of the upper tray and the lower tray are finely sanded to increase the friction between them and the elastic membrane.

[0014] Optionally, the elastic membrane is a low-viscosity, low-precipitation, non-silicon material with a thickness of 30–120 μm.

[0015] Optionally, the protrusion and the groove are fitted with a gap, and when the protrusion presses the elastic membrane into the groove, the protrusion and the groove are fitted tightly.

[0016] Optionally, after the elastic membrane is sandwiched between the upper tray and the lower tray, the membrane is not directly exposed to the outside world, preventing it from curling or detaching due to long-term use.

[0017] Optionally, the lower tray is provided with a vent hole communicating with the groove to prevent the formation of air pockets between the elastic membrane and the groove during the compression process.

[0018] Optionally, the bottom of the lower tray is covered with an adhesive layer to prevent the tray from sliding and falling off the platform. The adhesive layer is applied to the bottom of the lower tray and covers the vent holes after the upper tray, the elastic membrane, and the lower tray are combined.

[0019] Optionally, the size of the through hole is matched with the size of the lens to ensure that the lens remains stable and does not tip over when the tray is tilted or subjected to vibration.

[0020] Optionally, both the protrusion and the outer contour of the groove are circular, and the through hole is square.

[0021] The beneficial effects of this utility model's technical solution are:

[0022] This invention employs an upper and lower tray clamping structure for the elastic membrane, preventing the membrane from being directly exposed to the outside environment and avoiding edge curling, aging, and detachment due to long-term use. The protrusions press the membrane into the groove, forming a lens support groove. The membrane adheres to the groove surface at a pre-stretch rate of 1% to 3%, preventing air pockets and improving the stability of the lens bottom surface. The through-hole matches the lens size, ensuring accurate lens placement and preventing tipping during transport. The specific ratio between the groove depth and the lens height effectively limits positioning while preventing the lens from being completely embedded, which would make removal difficult. Vent holes effectively expel air during membrane insertion, preventing air pockets. The chamfered design prevents damage to the membrane edges, and the frosted surface increases friction between the membrane and the tray, extending the overall service life. The adhesive layer at the bottom of the lower tray further prevents slippage and improves overall transport safety. Attached Figure Description

[0035] In this embodiment, the protrusion and the groove are fitted with a gap, and when the protrusion presses the elastic membrane into the groove, the protrusion and the groove are fitted tightly.

[0036] In this embodiment, the elastic membrane is sandwiched between the upper and lower trays, so that the membrane is not directly exposed to the outside world, preventing it from curling or detaching due to long-term use.

[0037] In this embodiment, the lower tray is provided with a vent hole that communicates with the groove to prevent the formation of air pockets between the elastic membrane and the groove during the compression process.

[0038] In this embodiment, the bottom of the lower tray is covered with an adhesive layer to prevent the tray from sliding and falling off the platform. The adhesive layer is applied to the bottom of the lower tray and covers the vent holes after the upper tray, elastic membrane and lower tray are combined.

[0039] In this embodiment, the size of the through hole matches the size of the lens to ensure that the lens remains stable and does not tip over when the tray is tilted or subjected to vibration.

[0040] In this embodiment, the outer contours of both the protrusion and the groove are circular, and the through hole is square.

[0041] The following description will further illustrate the characteristics and functions of this utility model.

[0042] This embodiment provides an ultra-small lens carrier tray, including a lower tray 1, an upper tray 2, and an elastic membrane 3 sandwiched therebetween.

[0043] The surface of the lower tray 1 is provided with an array of grooves 11. The depth of the grooves 11 is 0.45 to 0.60 times the height of the supported lens, so as to both limit the movement and prevent the lens from being completely trapped and difficult to remove. Each groove has an exhaust hole 12 at its bottom or periphery. When the upper tray 2 presses the elastic membrane 3 into the groove 11, the exhaust hole 12 can expel air and prevent the formation of air pockets.

[0044] The upper tray 2 has a protrusion 21 corresponding to the groove 11, and a through hole 22 is provided in the protrusion 21. The size of the through hole 22 matches the outer dimensions of the lens. When the lens is loaded, it is inserted through the through hole 22, and the bottom surface of the lens contacts the elastic membrane 3 pressed into the groove 11, thereby forming flexible support and limiting. Preferably, the depth of the through hole 22 is 0.45 to 0.60 times the height of the lens.

[0045] The protrusion 21 of the upper tray 2 and the groove 11 of the lower tray 1 both have rounded chamfers on their opposite surfaces to prevent the elastic membrane 3 from being cut by sharp edges during the pressing process. At the same time, the gap fit between the protrusion 21 and the groove 11 allows the protrusion 21 to form a tight fit when pressing the membrane 3 into the groove 11, improving the overall stability.

[0046] The elastic membrane 3 is preferably made of a low-viscosity, low-exudation, non-silicon polymer material with a thickness of 30–120 μm. After being sandwiched between the upper tray 2 and the lower tray 1, the membrane has a pre-stretch ratio of 1%–3% in the area where it is locally pressed into the groove 11. This pre-stretching avoids air pockets between the membrane and the groove and enhances the adhesion stability of the lens bottom surface. Because the elastic membrane is sandwiched between the upper and lower trays and is not directly exposed to the outside environment, it avoids warping or detachment of the membrane due to long-term use.

[0047] An adhesive layer 13 is provided on the bottom of the lower pallet 1. This adhesive layer increases the friction between the lower pallet 1 and the transport platform, preventing the pallet from sliding and falling. The adhesive layer is attached to the bottom of the lower pallet after the pallet is assembled, and also covers the vent 12, without affecting the pallet's venting function.

[0048] In use, the operator simply inserts the lens through the through hole 22, and it is stably stored in the flexible limiting groove formed by the elastic membrane 3 and the groove 11. The lens remains stable even when the tray is handled, tilted, or subjected to vibration, and will not tip over or scatter.

[0049] In summary, this utility model employs an upper and lower tray clamping elastic membrane structure, preventing the membrane from being directly exposed to the outside environment and avoiding edge curling, aging, and detachment due to long-term use. The protrusions press the membrane into the groove, forming a lens support groove. The membrane adheres to the groove surface at a pre-stretch rate of 1% to 3%, preventing air pockets and improving the stability of the lens bottom surface. The through hole matches the lens size, ensuring accurate lens placement and preventing tipping during transport. The specific ratio between the groove depth and the lens height effectively limits positioning and prevents the lens from being completely embedded, which would make removal difficult. Vent holes effectively expel air during membrane insertion, preventing air pockets. The chamfered design prevents damage to the membrane edges, and the frosted surface increases friction between the membrane and the tray, extending the overall service life. The adhesive layer at the bottom of the lower tray further prevents slippage and improves overall transport safety.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
