2nd, adhesive tape group is taken：Adhesive tape group includes upper mould release membrance, on the lower surface of upper mould release membrance with dispensing position pair on liquid crystal display The position answered is covered with left and right adhesive tape block, and dispensing mouth is provided with left and right adhesive tape block, is pasted respectively on the bottom surface of left and right adhesive tape block It is covered with lower mould release membrance；The position that the both sides of upper mould release membrance correspond to left and right positioning vertical column in supporting plate is respectively equipped with size matching Punching hole.
3rd, liquid crystal display is taken, liquid crystal display is placed in stopper slot.
4th, upper mould release membrance both ends are held, upper mould release membrance are taken to above supporting plate, lower mould release membrance of tearing, then by punching hole Left and right positioning vertical column corresponding to being inserted in, pushes mould release membrance, left and right adhesive tape block is pressed to the dispensing position for pasting liquid crystal display, Finally tear upper mould release membrance, now, left and right adhesive tape block is pasted onto the dispensing position of liquid crystal display and surrounds dispensing chamber with liquid crystal display.
5th, with spot gluing equipment to the quantitative RTV in dispensing chamber midpoint, the viscosity of the RTV is 2000-3000cp, treats that RTV is automatic Left and right adhesive tape block of being torn after levelling and coagulation forming completes some glue process.
A kind of described operating method that can effectively control dispensing thickness on liquid crystal display, it is characterised in that：In the RTV The percentage by weight of each raw material components is：Silicon rubber 90-110, calcium carbonate 85-145, silicone oil 3-20, dimethylbenzene 3-8, turpentine oil 0.1-0.3, lemon oil 0.02-0.08, nano diatomite 0.2-0.4, crosslinking agent 4-9, catalyst 0.3-2.1.
A kind of described operating method that can effectively control dispensing thickness on liquid crystal display, it is characterised in that：The crosslinking Agent is amide groups silane crosslinker or alkoxy silane cross linked dose of functionality.
A kind of described operating method that can effectively control dispensing thickness on liquid crystal display, it is characterised in that：The catalysis Agent is organic tin catalyst.
Advantages of the present invention：
The inventive method is simple to operate, and dispensing chamber is formed between liquid crystal display after adhesive tape block is pasted into liquid crystal display, this Individual dispensing chamber have the function that to RTV well it is spacing, prevent overflow Huaping phenomenon generation.In addition, as requested, strict control Dispensing amount is made, thickness for dispensing glue after the solidification of RTV levellings is ensure that, ensures that there is best buffering effect to liquid crystal display.
