Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated, be to be understood that, specific embodiment described herein is only in order to explain the utility model, and is not used in restriction the utility model.
As Figure 1-4, the utility model is by the fit structure of the following narrow frame of 0.35mm of tool, comprise laminating component 1, glue-dropping tool 2 and pressurize tool 3, described laminating component 1 comprises applying glue object 11 and bonded object part 12, applying glue object 11 in laminating component 1 and bonded object part 12 are after glue-dropping tool 2 posts, be placed in again pressurize tool 3, by a glue, laminating, three steps of pressurize, by firm to applying glue object 11 and bonded object part 12 bonding become as a whole.
As shown in Figure 2, described applying glue object 11 frames are provided with roughened layer 111, and described bonded object part 12 frames are provided with the active layer 121 corresponding with described roughened layer 111, bonding by adhesive layer between described roughened layer 111 and described active layer 121.Wherein said applying glue object 11 is supporting cover, bonded object part is PC(English name: Polycarbonate, polycarbonate) base material, described roughened layer 111 is located at described supporting cover edge, the passable material of described supporting cover can be for using the metal materials such as magnesium alloy, aluminium alloy, SUS, or be PA, the plastic materials such as PA+GF.
Bonding by adhesive layer by roughened layer 111 and active layer 121, can greatly promote the bonding force of adhesive layer, strengthen tightness, ensure product quality.
Concrete, roughened layer 111 has two kinds of preferred structures:
The first, the structure of described roughened layer 111 for adopting blasting treatment mode to carry out roughening treatment.By on the 300-500 object quartz sand supporting cover bonding plane that high velocity jet is made to magnesium alloy materials or other materials under compressed-air actuated effect, utilize impact and the shear action of sand material to surface of the work, make surface of the work obtain certain roughness, increase the bonding force between supporting cover and PC.
The second, the structure of described roughened layer 111 for adopting laser micropunch mode to carry out roughening treatment.Utilize the laser beam irradiation of certain energy on magnesium alloy metal material, control the energy of laser, metal surface absorbs energy and forms the hole of certain depth, thereby reaches increase surfaceness, promotes the object of bonding force.
Concrete, described active layer 121 has two kinds of preferred structures:
The first, described active layer 121 is for adopting corona treatment mode to carry out the structure of activation processing.Under the effect of highfield, allow the ion producing after air ionization, impact the surface of PC material, make its surface chemistry bond rupture, increase surfaceness, thereby reach the object that promotes cohesive force.
The second, described active layer 121 is for adopting the structure in the processing of described bonded object part surface spraying priming paint mode.By primer(priming paint or subbing at PC substrate surface spraying certain material), between adhesive layer and PC part, play bridge joint effect, promote bonding strength.
As shown in Figure 3, described glue-dropping tool 2 comprises tool base 21 and tool upper cover 22, on described tool base 21, be provided with the draw-in groove 211 for placing applying glue object 11, described applying glue object 11 is fastened in described draw-in groove 211, described bonded object part 12 covers on described applying glue object 11, and described tool upper cover 22 covers on described bonded object part 12.Its implementation process is: applying glue object 11 supporting covers are placed on tool base 21, and the tool upper cover 22 that closes thereafter assembles rear placement 2-3min.Adhesive layer utilizes the flatness of the accuracy correction supporting cover of tool, so that can be coated on the applying glue region of supporting cover uniformly.Adopt syringe needle suitable point gum machine, control the travelling speed of dispensing needle head well.After some glue, form adhesive layer, the thickness of adhesive layer is 0.1-0.2mm.Again then, bonded object 12 is positioned on the supporting cover of having put glue, applies the laminate pressure of 5-10Kg, 110-120 DEG C of baking 30min left and right, and pressing 30S left and right.
As shown in Figure 4, also comprise pressurize tool 3, described pressurize tool 3 comprises upper cover 32 and lower cover 31, fastening being placed between described upper cover 32 and described lower cover 31 of laminating component 1 that described pressurize tool 3 completes laminating.Its concrete fastening means is: described upper cover 32 is provided with buckle 321, and described lower cover 31 is provided with buckle slot 311, and described upper cover 32 is fixedly connected with described buckle slot 311 by described buckle 321 with described lower cover 31.The laminating component 1 that assembling is posted is placed in pressurize tool 3, the 5Kg that exerts pressure, and pressurize 4h, with further firm laminating.
Preferably, the width of described adhesive layer is 0.18mm～0.35mm.The width of adhesive layer is lower, and screen display area increases relatively, more can meet people's visual demand.And the type selecting of adhesive layer is mainly selected epoxy systems glue bonding between adaptive PC base material and magnesium alloy, fastening effect is good.
The width of described adhesive layer also can be greater than 0.35mm, the width of adhesive layer can make more greatly bonding more firm, but because the viewing area of wanting considering screen, so the width of adhesive layer should be moderate, accomplish to ensure bonding steadiness, can ensure again larger screen accounting.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendments of doing within spirit of the present utility model and principle, be equal to and replace or improvement etc., within all should being included in protection domain of the present utility model.
