Fig. 1 is the schematic cross-section of SMT web plate of the prior art, and 1 is screen frame among the figure, the 2nd, and Shi Min beats firmly, and the 3rd, grenadine, the 4th, protection glue.In the inboard of screen frame 1, quickly beat hard 2 owing to execute not to the limit, quickly beat hard 2 so protect glue 4 to cover fully to execute; But in the outside since when slicing off unnecessary grenadine 3 to the limit, quickly beat hard 2 so execute also to the limit, protection glue 4 can't cover fully, executing of exposure quickly beaten hard 2 parts and just caused the infiltration of cleaning agent easily, thereby causes grenadine 3 to come off.
Summary of the invention
For solving the deficiency of prior art, the object of the present invention is to provide a kind of anti-cleaning sealing web plate, quick the beating of executing of screen frame edge covered with protection glue fully firmly, prevent that the cleaning agent corrosion from executing quick beating firmly.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of anti-cleaning sealing web plate; Comprise that screen frame, grenadine, Shi Min beat hard and ground floor protection glue; The periphery of described grenadine is fixed on the screen frame through executing quick beating firmly; Shi Min beats firmly the outside at screen frame to the limit, and inboard less than the limit, the grenadine on screen frame and Shi Min beat hard top covering ground floor and protect glue; The quick outside of playing hard, grenadine, ground floor protection glue of executing around it is characterized in that on the screen frame is sliced off a part, also is coated with one deck second layer on the top of screen frame that exposes and ground floor protection glue and protects glue.
Aforesaid anti-cleaning sealing web plate, around on the screen frame that it is characterized in that slicing off to execute the quick width of playing hard, grenadine, ground floor protection glue be 3mm.
The invention has the beneficial effects as follows: anti-cleaning sealing web plate of the present invention adopt with the outside to executing of limit quickly beat firmly, grenadine and protection glue slices off; At skin covering protection glue once more; Thereby make that executing quick beating is coated under the protection glue firmly fully, utilize double shielding glue to protect, prevented that effectively cleaning agent is to executing the quick hard corrosion of beating; Under the constant situation of existing material cost; Perfectly solved between grenadine and the screen frame and be cleaned the phenomenon that comes off that the agent corrosion causes firmly, in the service life of having improved the SMT web plate, guaranteed production owing to executing quick beating.
