A high-efficiency cleaning device for finished optical glass lenses

Abstract

This invention discloses a high-efficiency cleaning device for finished optical glass lenses, belonging to the field of optical lens conveying technology. It includes a centralized heating tank and a conveying track seat mounted on a support base. The centralized heating tank has a removable lid at its end, which is connected to a fixed-distance conveying disc via a pushing conveyor. A lens adhesive impurity cleaning unit, a lens rotation deburring unit, and a conveying unit are sequentially arranged on both sides of the conveying track seat. This invention addresses the burr problem present after lens slicing. During the sequential conveying of lenses through the conveying grooves on the intermittent conveyor belt, suction cup-type drive components on both sides of the conveying track seat rotate the lenses. During rotation, the deburring components gradually grind the originally right-angled cut edges into bevels, effectively removing burrs from the cut edges and preventing them from entering the lens surface and causing quality defects during subsequent double-sided grinding. This significantly improves the lens processing yield.

Description

[0035] The distance that the electric push rod 13 is pushed each time is the thickness of the lens, so as to ensure the effect of conveying each layer of lenses layer by layer.

[0036] It should be noted that the glass columns stuck together during the cutting process can be stuck together to the size of the inner diameter of the centralized heating tank body 1, which can ensure that the glass columns can be placed in the centralized heating tank body 1 after switching.

[0042] It should be noted that the glue that has lost its stickiness is transported along with the lens, and the cleaning brush tubes 8 arranged on both sides will clean and scrub the surface of the lens. The glue around and on the surface of the lens will be cleaned by the cleaning brush tubes 8 to remove the expired glue.

[0043] The lens rotation deburring unit includes a burr trimming device arranged on both sides of the conveying groove 6. Furthermore, the burr trimming device includes a burr trimming piece 19 fixedly arranged on the side walls of the conveying groove 6 on both sides, which can be set as grinding and cutting blades according to the material. An arc-shaped connecting groove is opened on the inner wall of the conveying groove 6. The inner wall of the arc-shaped connecting groove is connected to an arc-shaped contact seat 20 located in the conveying groove 6 through a contact spring. The lens is placed in the conveying groove 6, and its bottom is in contact with the arc-shaped contact seat 20. Under the action of the pressure of the arc-shaped lower pressure strip 9, the lens will be squeezed and moved downward, so that the arc-shaped contact seat 20 moves into the arc-shaped connecting groove. At this time, both sides of the lens will contact the burr trimming piece 19, and the rotating lens will be trimmed to remove burrs.

[0044] An arc-shaped lower pressure strip 9 is arranged at the top of the conveying track seat 2, and a transverse conveying belt 10 is arranged on the support seats on both sides of the conveying track seat 2. The transverse conveying belt 10 is a kind of existing transmission belt and will not be described in detail here. The transverse conveying belt 10 is evenly provided with suction cup-type driving parts for driving the optical glass to rotate.

[0045] Furthermore, the suction cup type driving member includes a rotating sleeve 24 rotatably arranged on the transverse conveyor belt 10, the rotating sleeve 24 is connected to the extrusion column 25 through a keyway sliding member 26, a suction cup is arranged at the end of the extrusion column 25, a rectangular through-hole is opened on the side wall of the conveying track seat 2, the rectangular through-hole is provided for the suction cup to contact the lens inside, and the other end of the extrusion column 25 is connected to the rotating sleeve 24 through a pressure spring.

[0046] When the transverse conveyor belt 10 turns, the suction cup will gradually turn and come into contact with the lens being conveyed. Under the pressure of the squeezing column 25, the suction cup will be adsorbed on the lens to achieve a tightening connection effect.

[0047] A rotating gear 28 is fixedly connected to the outer wall of the rotating sleeve 24, and a fixed rack 27 meshing with the rotating gear 28 is fixedly connected to the support seat. The moving rotating gear 28 will contact the fixed rack 27, and the rotating gear 28 will be driven to rotate while in contact.

Its structural setting can realize the sliding connection between the rotating sleeve 24 and the extrusion column 25, and can also realize the rotational transmission.

[0049] When the present invention is used, the cut lenses are placed between the distribution columns 14, the detachable tank cover 3 is installed with the centralized heating tank body 1, and the high-pressure steam is controlled to be transported into the high-pressure steam transport cover 11. The steam of the high-pressure steam transport cover 11 distributed around the central heating tank body 1 will quickly and evenly heat the lenses in the centralized heating tank body 1. Under the action of the high-pressure steam, the lenses in the centralized heating tank body 1 and the glue adhering between the lenses are heated. During the heating process, the glue adhering to the surface of the lenses will be heated and ineffective, so that the lenses adhering to each other will be separated from each other.

[0050] The electric push rod 13 is controlled to drive the fixed-distance conveyor disc 4 to convey gradually. Each layer of lenses in the centralized heating tank 1 will be squeezed and conveyed. The lenses at the end will be squeezed and conveyed downward to the continuously moving interval conveyor belt 5 under the action of the squeezing semicircular plate 16. At this time, the lenses in the conveying groove 6 will be driven to be conveyed into the conveying track seat 2. The continuously conveyed lenses will be processed by the lens adhesive impurity cleaning unit and the lens rotation deburring unit in turn during the movement.

[0051] The lens being conveyed will move following the drive of the interval conveyor belt 5. During the movement, the moving lens will contact the suction cup type driving parts arranged on both sides. The suction cups arranged on the driving parts will contact and adsorb the surface of the lens. The moving self-rotating gear 28 will contact the fixed rack 27 and be driven to rotate while in contact, so that the extrusion column 25 connected to the self-rotating gear 28 through the rotating sleeve 24 will rotate, driving the lens to rotate. At this time, the upper part of the lens contacts the arc-shaped lower pressure strip 9 and is driven to be pressed down. The rotating lens will gradually contact the burr trimming parts 19 arranged on both sides of the conveying groove 6, and gradually grind the original right-angle cutting edge into a bevel, thereby avoiding the existence of burrs causing quality defects during the subsequent double-sided grinding of the lens.
