Abstract

The utility model discloses a bonding fixture which comprises a base seat. The base seat is provided with an upright step trough, the step trough comprises a die cavity groove, a floating pile with adjustable height is arranged on the first side of the base seat adjacent to the die cavity groove, and a first supporting plate and a second supporting plate which are mutually symmetrical and provided with adjustable height are respectively arranged on the second side and the fourth lateral surface of the base seat adjacent to the die cavity groove. By adopting the bonding fixture of the utility model, when bonding material is positioned into the die cavity groove, the bonding material at the lower part can not be moved, simultaneously, when organic resin film is bonded on glass coated with ultraviolet curing adhesive, because of the blocking of the floating pile, the bonding material at the upper part can also not be moved, therefore, the deviation problem of the bonding material can be well solved; simultaneously, because of the supporting of the first supporting plate and the second supporting plate at both ends of a roller, the acting force of the downward pressing of the roller can be well controlled, and the coating uniformity of the ultraviolet curing adhesive can be ensured.

Description

The applying anchor clamps

[technical field]

The utility model relates to a kind of applying anchor clamps.

[background technology]

All use glass-mirror on the now increasing mobile phone, all use glass-mirror as the most of high terminal in the N series of the V series of Motorola, Nokia, glass-mirror has advantages such as intensity height, damage resistant.And the minute surface of acrylic material manufacturing causes the blemishes on mobile phone surface with regard to being easy to be scratched, and therefore, glass just becomes the substitute of acrylic material in the minute surface field.But, in the category of high terminal, become human consumer's new focus about the breakable shortcoming of glass, therefore, in minute surface field in 2006, just developed the technology of adhering to rupture disk (polyethylene terephthalate (Poly Ethylene Terephthalate)+two-sided glued membrane (PSA)) at glass surface, like this problem with regard to solving the glass cracky, splashing.But, this technology can only be decorated on glass, as printed patterns or plated film, be easy to cause strength of glass to descend, as: the chemical ingredients of decoating liquid can cause glass surface hardness to descend, minute surface needs to have anti-ability of pushing and buffering effect in the mobile phone assembling on liquid crystal display on the other hand, promptly prevents to clash into liquid crystal display and influences display effect, so just conflicts with ultra-thin again.Adopt the technology of glass gluing organic resin film such as polycarbonate (PC) film or polymethacrylate (PMMA) film to address the above problem simultaneously, this technology is at coating ultraviolet light curing glue on glass, be fitted in PC film or PMMA film on glass then, and can be directly at the enterprising luggage decorations of applying film, can not influence the anti-ability of pushing and the buffering effect of glass, and the function that on glass-mirror, has anti-glass to splash equally.

At present, in the technology of applying organic resin film on glass, usually the mode that adopts manual assembly directly with organic resin film by ultraviolet cured adhesive attached on glass, but, this ultraviolet cured adhesive is a liquid, have certain thixotropy, manual assembly easily causes the skew of organic resin film because of the thixotropy of ultraviolet cured adhesive; In addition, manual assembly needs later on to fit with roller roll extrusion organic resin film, and firmly size is uncontrollable for ultra-violet curing glue during the roller roll extrusion, and it is uneven to cause the ultraviolet light binding to apply.

[summary of the invention]

Technical problem to be solved in the utility model provides a kind of applying anchor clamps that prevent to cause because of the thixotropy of ultraviolet cured adhesive the organic resin film skew.

The technical problem that the utility model further will solve provide a kind of during because of the roller roll extrusion ultra-violet curing glue firmly size is uncontrollable, cause the ultraviolet light binding to apply uneven applying anchor clamps.

The utility model is achieved through the following technical solutions:

A kind of applying anchor clamps comprise substrate, and this substrate has vertical step trough, and this step trough comprises the die cavity groove, and first side near the die cavity groove in substrate has adjustable for height floating stake.

Described floating stake has at least two first fixed installation holes, is arranged with first fixing part and elastic element in the first fixed installation hole, and described floating stake passes elastic element by first fixing part and the first fixed installation hole is arranged in the substrate.

Second side and the 4th side near the die cavity groove in the described substrate have symmetric adjustable for height first back up pad and second back up pad respectively.

Described first back up pad and second back up pad have at least two second fixed installation holes and the 3rd fixed installation hole respectively, the second fixed installation hole and the 3rd fixed installation are arranged with second fixing part and the 3rd fixing part respectively in the hole, and described first back up pad and second back up pad are passed the second fixed installation hole and the 3rd fixing part by second fixing part respectively and passed the 3rd fixed installation hole and be arranged in the substrate.

Described step trough also comprises the glue letdown tank that overflows, and the ladder between described excessive glue letdown tank and first back up pad and second back up pad forms rail groove, and the size of described die cavity groove, overflow glue letdown tank and rail groove increases from the bottom to top gradually.

Also be provided with the groove that picks and places that picks and places laminated material on the described rail groove.

Described die cavity groove has the vacuum hole that communicates with vacuum pipe.

The beneficial effects of the utility model are:

The utility model adopts and in substrate step trough is set, first side near the die cavity groove has adjustable for height floating stake in substrate simultaneously, when laminated material (such as at applying organic resin film on glass) when being placed in the die cavity groove, below laminated material (such as glass) be fixed on can not produce in the die cavity groove mobile, when when being coated with the applying organic resin film on glass of ultraviolet cured adhesive, because stopping of floating stake arranged, so top laminated material (such as organic resin film) can not produce mobile phenomenon yet, therefore can well overcome the offset problem of laminated material.

Second, described substrate has symmetric adjustable for height first back up pad and second back up pad respectively near second side and the 4th side of die cavity groove, first, ladder between second back up pad and the excessive glue letdown tank is formed with rail groove respectively, when carrying out the material applying, can be by adjusting the height of first back up pad and second back up pad, it is just equal with the plane of organic resin film that the roller that is positioned at rail groove is pressed to, because there is the support of first back up pad and second back up pad at the two ends of roller, therefore can fine debugging and the reactive force that presses down of control roller, guaranteed the homogeneity that ultraviolet cured adhesive applies.

Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
