Description
Technical Field
The invention relates to the technical field of optical glass assembly mounting, in particular to a dispensing method suitable for a narrow dispensing surface on an optical glass assembly.
Background
In the process of automatically assembling the optical glass and the Holder by using a machine (the process of attaching the optical glass to a specified position to be attached by using the machine), when mass production is carried out, glue needs to be uniformly coated on a glue dispensing surface through a rubber tube and a needle head by using an automatic glue dispensing device in the machine, the size of the needle head is limited, the glue dispensing surface is usually required to be larger than or equal to 400um in width to ensure that glue overflows within 0.08mm, and the optical glass with the glue dispensing surface smaller than 400um basically does not have mass production performance.
Disclosure of Invention
The invention provides a dispensing method capable of realizing mass production dispensing of optical glass with a dispensing surface less than 400 mu m, aiming at an optical glass assembly with a narrow dispensing surface and a wider side wall vertical to the narrow dispensing surface, aiming at solving the dispensing problem of the narrow dispensing surface on the optical glass.
In order to achieve the above object, the present invention adopts the following technical scheme that a dispensing method of a narrow dispensing surface comprises a dispensing machine and optical glass to be dispensed, wherein the dispensing machine comprises a dispensing needle head and an image recognition device, the optical glass comprises a dispensing surface and a side wall vertical to the dispensing surface, the width of the dispensing surface is less than 400um, the length of the side wall vertically extending from the boundary with the dispensing surface is not less than 400um, the inner diameter of the dispensing needle head of the dispensing machine is 210um, and the outer diameter of the dispensing needle head of the dispensing machine is 400 um; the dispensing method comprises the following steps: 1) manufacturing a correct dispensing pattern of the optical glass to be dispensed in advance; 2) horizontally placing an optical glass dispensing surface to be dispensed with glue, wherein the side wall is positioned above the dispensing surface; 3) arranging a dispensing needle head of the dispenser to be vertical to the side wall; 4) performing image recognition on the optical glass to be subjected to glue dispensing, and keeping the center of a glue outlet of the glue dispensing needle head consistent with the center of the image of the optical glass to be subjected to glue dispensing; 5) the glue dispenser tries to spot glue on the optical glass to be glued, and the glue dispensing parameters are adjusted according to the glue dispensing figure collected in real time so as to enable the glue dispensing parameters to be in accordance with the glue dispensing figure made in advance. The technical scheme is also based on industrial visualization equipment, a glue dispensing method is improved, glue is directly dispensed on an optical glass glue dispensing surface, glue is dispensed on a side wall vertical to the glue dispensing surface, then the glue automatically flows to the glue dispensing surface by utilizing gravity and the mobility of the glue, meanwhile, due to the action of the surface tension of the glue, the glue is gathered at a right angle formed by the glue dispensing surface and the side wall, and the glue overflowing probability is reduced.
Preferably, the dispensing needle head of the dispenser adopts a 27G 45-degree inclined needle head.
Preferably, the outer diameter of the dispensing needle of the dispenser is polished to 260 and 280 microns. The outer diameter of the needle head is polished to 260-280um from 400um, so that the needle head is easier to operate and adjust the position without unnecessary collision with optical glass to be dispensed in the dispensing process.
Preferably, the viscosity of the glue adopted by the glue dispenser is less than or equal to 60000 cp. The glue of the scheme not only needs to consider the bonding fastness, but also needs to consider the flowability of the glue, and the higher the viscosity, the poorer the flowability of the glue, so that the glue of the scheme is better when the viscosity is not more than 60000 cp; cp is the viscosity unit and Chinese is centipoise.
The principle of the scheme is as follows: the height of the side wall of the dispensing face is larger than the width of the dispensing face, so that the glue can be completely attached to the side wall, then the glue part flows to the dispensing face by utilizing the principle that gravity is downward, and meanwhile, because the side wall is vertical to the dispensing face, a large amount of glue can be adsorbed inside a formed right angle, and the occurrence probability of glue overflow is reduced.
The lower limit of the mass production that the width of the dispensing surface of the existing optical glass and Holder assembly is at least larger than or equal to 400um can be reduced to about 100um by the scheme, and quantitative assembly can be carried out on products that the height of the side wall of the dispensing surface is larger than or equal to 400um and the width of the dispensing surface is larger than or equal to 100um by the scheme.
Therefore, the invention has the following beneficial effects: the method is simple to operate and flexible to use, can realize mass production of the optical glass with the dispensing surface less than 400 mu m, and solves the problem of actual production.
