Abstract
The utility model relates to a high-flatness deformation-preventive electromagnetic whiteboard, which sequentially comprises a face plate, an upper adhesion layer, a polystyrene plate, a lower adhesion plate and a back plate from top to bottom. A plurality of upper grooves which are staggered longitudinally and transversally are arranged on the upper surface of the polystyrene plate, coil sensors are embedded in the upper grooves, and upper reinforcing ribs which are inserted in the upper grooves extend downwards from the lower surface of the upper adhesion layer. Compared with the prior art, the high-flatness deformation-preventive electromagnetic whiteboard has the advantages that the structure is simplified, non-woven fabrics and corresponding adhesion layers are omitted, material cost and processing cost are saved, pitches of the embedded sensors with crossed grid coils are more uniform, wire scattering is precluded, products are more stable, positioning is more accurately positioned, exposed metal wires are omitted, scrap of products due to the fact that the coils are broken or are in short circuit during production is avoided, the reinforcing ribs are respectively formed on the front and the back of the high-flatness deformation-preventive electromagnetic whiteboard, the rigidity and the bending and deformation resistance of the integral structure are strengthened, and accordingly bending deformation due to uneven stress is effectively avoided.
Description
Technical field
The utility model relates to a kind of interactive electromagnetism blank, is specifically related to a kind of high flatness and distortion-free electromagnetism blank.
Background technology
Existing electromagnetism interactive electronic white board is made up of overlay film duroplasts panel, adhesive layer, nonwoven, plain conductor inductive layer, adhesive layer, cystosepiment, adhesive layer and duroplasts backboard to the common structure of the back of the body from face successively; There is loose wire in the compilation process of plain conductor inductive layer; The defective that spacing is uneven; Thereby cause that product orientation is inaccurate, the wire jumper breakpoint is bad etc.; The technology of adhesive layer and existing adhesive receive the influence of variations in temperature and humidity bigger, and the drum that come unstuck easily deforms.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of high flatness anti-deformation electromagnetism blank, and its flatness is higher relatively, and is difficult for deforming.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
High flatness anti-deformation electromagnetism blank; Comprise panel, last adhesive layer, XPS, following adhesive layer, backboard from top to bottom successively; The upper surface of said XPS offers crisscross a plurality of upper grooves; Be embedded with coil pickoff in the said upper groove, the said lower surface of going up adhesive layer is extended with the last ribs that is inserted in the upper groove downwards.
The spacing of adjacent two upper grooves that vertically are provided with equates that the spacing of adjacent two upper grooves of horizontally set equates.
The lower surface of said XPS offers a plurality of low grooves that are arranged side by side, and the said upper surface of adhesive layer down extends upward the following ribs that is inserted in the low groove.
The spacing of adjacent two low grooves equates.
The beneficial effect of the utility model is:
1, simplifies the structure, save nonwoven and corresponding adhesive layer, saved fee of material and processing cost;
2, the spacing of embedded intersection graticule line coil sensor is more even, stops loose wire, makes product more stable, more accurate positioning, and the metal wire that does not expose has been avoided pulling apart coil in process of production or coil short is caused scrapping;
3, front and back forms ribs respectively, has strengthened the rigidity and the counter-bending deformability of total, thus the stretch bending distortion of effectively avoiding the stress inequality to cause.
Description of drawings
Fig. 1 is the structural representation of a kind of high flatness anti-deformation electromagnetism blank of the utility model.
The specific embodiment
Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing:
As shown in Figure 1; A kind of high flatness anti-deformation electromagnetism blank for the utility model; It comprises panel 1, last adhesive layer 2, highdensity XPS 3, following adhesive layer 4, backboard 5 from top to bottom successively, and the upper surface of XPS 3 offers crisscross a plurality of upper grooves 31, wherein a plurality of 31 parallel to each other and equidistant arrangements of upper groove longitudinally; Same; A plurality of horizontal upper groove 31 parallel to each other and equidistant arrangements, orderly setting-in is equipped with coil pickoff 6 in the bottom of upper groove 31, and the lower surface of last adhesive layer 2 is extended with the last ribs 21 of criss-cross arrangement downwards; It is corresponding one by one with upper groove 31 to go up ribs 21, and plug-in mounting is filled in the upper groove 31; Above structure; Last adhesive layer 2 and XPS 3 contacts area have been increased on the one hand; Effectively increased the bonding force between last adhesive layer 2 and the XPS 3, on the other hand, last adhesive layer 2 and on last ribs 21 form the reinforcement structure of a T font; Flatness that can p-poly-phenyl vinyl plate 3 plays the effect of correction, strengthens the rigidity of total and the ability of counter-bending deformation simultaneously.In addition; Upper groove 31 has increased the order that coil pickoff 6 is arranged, the wire coil that the coil pickoff 6 after the while is embedded does not expose in order to setting-in coil pickoff 6; Make total succinct, in the production flow transportation, avoided the situation of pulling apart coil or making coil short.
In order further to increase the rigidity and the counter-bending deformation ability of whole electromagnetism blank; Lower surface at XPS 3 offers a plurality of low grooves 32, these a plurality of low groove 32 parallel to each other and equidistant arrangements, corresponding with it; The upper surface of following adhesive layer 4 extends upward the following ribs 41 of a plurality of parallel and equidistant arrangements; Following ribs 41 plug-in mounting one to one is filled in the low groove 32, and so, the flatness of p-poly-phenyl vinyl plate 3 plays further corrective action; Simultaneously, also increased the bonding force of XPS 3 with following adhesive layer 4.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
