In the optical cold machining process, the disc loading refers to a process in single or multiple lens machining, a glass element is fixed on a certain tool through a bonding material or an adsorption force, subsequent machining operations such as milling and grinding are facilitated, the disc loading process requires that the bonding and adsorption of the element are firm, and meanwhile, the dismounting operation in a subsequent process is facilitated.
At present, the upper disc of an optical element generally adopts the processes of manual single-chip dispensing, disc placing and upper disc hanging, and the process specifically comprises the following steps: (1) manually dispensing single pieces of asphalt, pouring the heated asphalt into a clamp, putting the lens workpieces to be processed one by one, and cooling for a period of time to enable the asphalt to be adhered to the lens workpieces and then be taken down; (2) uniformly swinging the processing surface of the lens workpiece downwards onto the surface of a sand mold; (3) and (3) uniformly pressing the heated upper disc die to the product after the disc is placed under a certain force, gradually adhering asphalt to the upper disc die when the asphalt is heated, and adhering the upper disc die and the lens workpiece together through the asphalt after the upper disc die is properly cooled, so that the lens can be processed.
The above-mentioned some glue hanging wall modes, there are the following disadvantages: 1. asphalt residues are left on the surface or the edge of a product after manual single-piece glue dispensing, a blade is required to be used for scraping and cleaning, and the processing working hour is required to be additionally increased; 2. the smaller the caliber specification of the lens to be processed is, the larger the manual dispensing difficulty is, and the manual asphalt dispensing processing efficiency cannot be improved.

In order to solve the technical problem, the invention provides a method for quickly loading a small-caliber lens, which comprises the following steps:
and 4, placing the surface of the bonding mold with the bonding glue on a baking plate, heating to 35-45 ℃, covering the bonding mold above the sand mold with the small-caliber lens, and enabling the heated bonding glue to be in contact with the small-caliber lens and vertically and downwards applying pressure until the bonding glue is cooled.
Further, the baffle plate is fixed on the peripheral edge of the bonding die base plate in a gluing mode.
Further, the adhesive glue is asphalt.
Further, the thickness of the adhesive glue uniformly distributed on the disc surface of the base plate of the bonding die in the step 2 is equal to 4 mm and equal to 6 mm.

Referring to fig. 1, a flow chart of the steps of the method for rapidly loading a small-caliber lens according to the present invention includes the following steps:
in the optical cold working process, a workpiece to be processed is usually fixed on a bonding die, and then the bonding die is fixed on equipment for polishing. According to the method, a circle of closed annular blocking piece is arranged on the peripheral edge of the bonding die substrate, the upper end edge of the blocking piece is higher than the disc surface of the bonding die substrate by more than 6mm, and the method has the functions of preventing the bonding glue from overflowing in the glue pouring process and controlling the thickness of the bonding glue. In a specific embodiment, the blocking sheet is fixed on the edge of the bonding die substrate in a gluing mode, and kraft paper and the like can be selected as simple materials for considering cost control and subsequent factors of convenient disassembly.
And 4, placing the surface of the bonding die with the bonding glue on a baking plate, heating to 35-45 ℃, covering the bonding die above the sand die with the small-caliber lens, enabling the heated bonding glue to be in contact with the small-caliber lens and vertically pressing downwards until the bonding glue is cooled, and fixing the workpiece to be processed and the bonding film substrate together to process on equipment. Preferably, after the bonding glue is heated to 35-45 ℃, the bonding glue can be softened and meet the bonding requirement. As shown in fig. 3, which is a schematic view of the upper plate of the small-caliber lens of the present invention, the method eliminates the tedious steps of single lens dispensing operation and scraping glue after lens dispensing in the existing manual processing mode by means of the manner of pre-pouring glue on the bonding film substrate and then batch arranging the plate, and simultaneously, the operation of the upper plate of the small-caliber lens is more concise and convenient and the efficiency of the upper plate is greatly improved by batch arranging and upper plate of the lenses.
