Embodiment 1
[0051] The size of the design medium is 55*60mm, and the CAD typesetting design and the drawing design of each process are carried out according to the size of the camera glass. The diameter of the 8mm wafer camera is 30pcs in the middle piece of the wafer camera. The layout is as follows figure 1 shown.
[0052] According to the design drawings, 0.5mm thick glass is selected for pre-cutting by laser, and the shape of the middle piece and the shape of the glass camera are cut out. After cutting, the leftovers on the edges are cracked.
[0053] Ultrasonic cleaning is carried out before the overall etching to remove glass chips and dirt on the glass. Control pickling conditions: 9% HF acid polishing solution, 30±2°C thinning and polishing for 15 minutes, use pickling polishing solution to reduce the thickness to 0.4±0.01mm, and simultaneously form a 4-10C arc-shaped chamfer on the edge of the glass;
[0054] Use a cleaning agent to clean the dirt on the glass surface. After cl...

Abstract
The invention provides a glass camera processing technology. The glass camera processing technology comprises the following steps: sequentially subjecting medium-sheet glass to rough shape cutting, laser pre-cutting, cleaning, acid pickling, thinning and polishing, cleaning, pressurizing, ultrasonic cleaning, wiredrawing, NCVM plating, silk-screen printing, deplating, silk-screen printing of codes, cleaning of a finished product, AR/AS plating and splitting so as to obtain a plurality of glass cameras. The procedure of laser pre-cutting specifically comprises a step of performing laser cuttingon the medium-sheet glass to form the shape of the middle glass and the shapes of the plurality of single-sheet glass cameras; a hydrofluoric acid polishing solution is adopted in the procedure of acid pickling, thinning and polishing; and the procedure of acid pickling, thinning and polishing is carried out at 25-35 DEG C for 15-25 min. The processing technology disclosed by the invention can realize synchronous processing of the plurality of finished single-sheet camera products from one medium sheet, greatly reduces production cost, improves production efficiency, and enhances the first pass yield of a production line.
Description
technical field [0001] The invention belongs to a glass camera processing technology, in particular to a glass camera processing technology. Background technique [0002] With the increase of production cost, the profit of the current monolithic glass camera processing technology has been severely squeezed, and there is even a serious situation of processing losses. Improving production efficiency and reducing production costs have become the only way to solve this situation. Contents of the invention [0003] The object of the present invention is to provide a glass camera processing technology. The process of the present invention can simultaneously process multiple single-chip glass cameras, with high pass-through rate, high efficiency and low cost. [0004] The invention provides a processing technology for a glass camera, comprising the following steps: [0005] The middle sheet glass is sequentially cut, laser pre-cut, cleaned, pickled and thinned and polished, cle...
