Description

Optical part machining device

Technical Field

The utility model belongs to optics parts machining equipment field, concretely relates to optics parts machining device.

Background

In the development process of optical devices, the conventional polishing method mainly comprises the processes of upper disc, grinding, rough polishing, fine polishing and lower disc. The upper disc and the lower disc are the most important two steps in the process, the upper disc is used for bonding optical parts on a rubber mold, common upper disc dispensing methods comprise an upper disc, an upper disc for light rubber, an upper disc for floating rubber and the like, the parts are generally bonded above a mold by using asphalt or other bonding agents so as to ensure the precision of the processed parts, and therefore a large amount of asphalt or bonding agents for bonding the parts, bonding time, lower disc time, cleaning time and cleaning agents are needed, the asphalt bonding parts, the upper disc and the lower disc are complicated in process, the steps of coating, heating, bonding, adjusting, cleaning and the like are needed, and labor cost and time cost are high.

The process of the upper plate and the lower plate has certain influence, for example, the plate can be dropped when the upper plate is processed, and if the condition occurs, not only certain risk exists for operators, but also the mirror surface can cause huge damage. Secondly, during hanging the disc, the situation that the mirror surface is attached to the bonding surface of the tool to cause errors is difficult to avoid, and the surface type of the part is difficult to accurately control. In the process of discharging the disc, due to the fact that large tensile force exists between glue and a lens, the lens is likely to deform or change greatly in size, and cannot meet the requirement of becoming a product, so that the lens becomes a defective product.

Disclosure of Invention

The main object of the utility model is to provide a simple, easy and simple to handle, reliable optical parts processingequipment, the purpose is used for solving present lens last lower wall process operation time long, dismantle that process time is long and the in-process can influence the qualification rate of lens, the binder consumption is big and be difficult for getting rid of, work efficiency is low, a great deal of circumstances such as manufacturing cost height.

In order to achieve the above object, the utility model mainly provides the following technical scheme:

the utility model provides an optical part processingequipment, includes semi-circular anchor clamps mould, the edge of anchor clamps mould has been seted up and has been sunk the platform to be provided with heavy platform assorted holding ring, holding ring and anchor clamps mould top all are provided with silicon rubber.

The silicon rubber has the effects of reducing the stress area of the part during processing, having stronger adsorption force with the part, and the adsorption part does not rotate along with the clamp die to cause surface flaws on the contact surface of the part and the clamp die, and the part does not need to be additionally sprayed with protective paint.

Further, the surface of the clamp die is a concave surface, a convex surface or a plane surface, and the radius of the clamp die is equal to the radius of the bonded optical part except the radius of the silicon rubber.

Further, the thickness of the silicon rubber is 0.5 mm-1.5 mm.

Further, the optical part is a lens or a mirror.

Use the utility model discloses an optical parts processingequipment, simple structure, easily operation, the product percent of pass is high. It not only saves 5 links of hanging wall, grinding, rough polishing, finish polishing, lower wall, still reduces the part simultaneously and additionally produces the stress in the bonding process and has effectively improved the processingquality of part, present operating procedure is simple as follows: the silicon rubber is arranged on the clamp die, and the part is placed on the silicon rubber and finally the positioning ring is covered, so that the problems that the working efficiency is low, the production cost is high, the product quality is low, the product percent of pass cannot meet the requirement and the like are solved, the economic benefit brought by the device is very considerable, and the device is convenient to popularize and use.
