Description
Technical field
The invention belongs to optical detections and reading code technical field more particularly to one kind to answer simultaneously tempered glass
Stress mornitoring and the miniature reading code integrated equipment of power detection and reading code.
Background technique
Tempered glass is also known as strengthened glass, it is a kind of prestressed glass, usually using method chemically or physically, in glass
Glass surface forms compression, and glass bears to offset surface layer pressure first when external force, so that bearing capacity is improved, thus tempering glass
Glass is widely used in the fields such as building doors and windows, glass curtain wall, electronic instrument.But tempered glass cutting back edge can exist largely
Micro-crack causes strength of glass to reduce.Especially with flourishing for touch-control industry, the specification requirement of touch-control product itself
It is increasingly stringent, since touch panel is to go the function mode for carrying out inductive component by the external pressure that applies to reach using effect
Fruit, therefore the mechanical compressive resistance of product is the important specification and index of all big enterprises.Under this market background, how quickly and
Glass surface stress accurately is measured, becomes the focal issue that tempered glass manufacturer and application quotient are concerned about.
Additionally, it is also well known that, in order to carry out subsequent tracking and managing to product, can generally produced in modern production industry
One-dimension code/two dimensional code mark is carried out on product, one-dimension code/two dimensional code is arranged according to certain coding rule, to express one group
The graphical identifier of information.Thus, during subsequent production, product identification also has become one in modern enterprise production process
A important link, needing reading code to know, otherwise installs one or one group of code reader carries out reading code under normal circumstances, so as to
Carry out quality control, production retrospect.
When carrying out stress mornitoring and product reading code to tempered glass currently on the market, need to be divided into stress mornitoring and product
Reading code two procedures carry out respectively, and the detection of the first procedure just can be carried out the product reading code of next process after completing.It is existing
This mode needs two sets of equipment of stress mornitoring and product reading code, need to occupy large area detection space, have to work-yard higher
It is required that while two sets of equipment, undoubtedly increase tempered glass testing cost.Importantly, two are arranged and need to be equipped with to the utmost less
