Description
Technical field
The utility model relates to a kind of plated film correcting plates, especially suitable for using when optical manufacturing curved reflector plated film.
Background technique
Currently, optical thin film production is usually based on physical vapor deposition, this method is to be by solid state transformed by thin-film material
The material of gaseous state or ionic state, gaseous state or ionic state passes through space by evaporation source, arrives at substrate surface, and material arrives at substrate surface
Afterwards, precipitating is gradually formed into film, existing curved reflector plated film is that its substrate is put into coating machine left-hand thread in rotation work
On part disk, the rotation of rotational workpieces disk, evaporation source passes through space and arrives at substrate surface during rotation, plated film is completed, due to song
The shape of face reflection is arch, it is uneven often to will appear film layer in coating process, so that film plating layer uniformity is difficult to
Guarantee, to influence product quality and production efficiency.
Summary of the invention
The task of the utility model can be corrected when proposing a kind of substrate film coating, and plated film is uniform, improves product qualification rate
Curved reflector plated film correcting plate.
The task of the utility model is done in such a way that it is characterized by: bracket is symmetrically fixed on the steaming of coating machine cavity
It the upper surface of rises, and bracket one end is fixed with cavity, and the bracket other end is towards overhanging in plated film body cavity body, on the bracket
Even to be provided with multiple fastener holes for being used to install correcting plate, the shape of correcting plate is in herring-bone form, and is processed on the back face of herring-bone form
There is fastener hole identical with bracket and be fastened by bolts, and the shark's fin of herring-bone form two sides just shelters from below coating machine cavity
Evaporation source.Wrap up one layer of refractory metal layer, the preferred masking foil of material in the front and back sides of the correcting plate.Curved reflector rotates on
On bracket when fixed correction Board position, evaporation source is sheltered from from shark's fin and sprays coating materials to curved reflector two sides.
The utility model has the effect that the technical program solves curved reflector unevenness in plated film, to mention
The qualification rate of high plated film improves product quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；Fig. 2 is the structural schematic diagram of correcting plate.
Drawing explanation: 1, coating machine cavity, 2, evaporation source, 3, bracket, 4, correcting plate, 5, rotational workpieces disk, 6, motor, 7,

Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
Specific embodiment is as depicted in figs. 1 and 2, and in the present embodiment, curved reflector button is placed on rotation work in plated film
Plated film is carried out on part disk, since curved reflector shape is domed, the intermediate position of curved surface and two sides are in plated film, evaporation source
Easily there is uneven thickness in injection coating materials, to cause reflectivity that non-uniform reflection is not achieved.
For this purpose, devising bracket and correcting plate in the present embodiment, and bracket is symmetrically fixed on the evaporation source of coating machine cavity 1
The upper surface of 2, and 3 one end of bracket is fixed with cavity, and the bracket other end is towards overhanging in plated film body cavity body, on the bracket uniformly
It is provided with multiple for installing the fastener hole of correcting plate.
The shape of the correcting plate 4 is in herring-bone form 8, and fastening spiral shell identical with bracket is machined with above the back of herring-bone form
Hole 9 is simultaneously fastened by bolts, and the shark's fin 10 of herring-bone form two sides just shelters from the evaporation source 2 below coating machine cavity, thus
Correct the generation of curved reflector two sides plated film non-uniform phenomenon.
One layer of refractory metal layer 11 is wrapped up in the front and back sides of the correcting plate, when due to plated film, coating materials that evaporation source is launched
It is easily adhered in the plate face of correcting plate, not easy cleaning, and the temperature in plated film cavity is up to 250 °, is easily dissolved with plastic wraps,
The preferred masking foil of the technical program, high temperature resistant are convenient for changing.
To sum up known, the technical program is overcome by bracket 3, correcting plate 4, herring-bone form 8, shark's fin 10, refractory metal layer 11
The uneven defect of prior art camber reflection plated film.
When work, 7 left-hand thread of curved reflector on rotational workpieces disk 5, correcting plate and bracket are fastened, start motor
6 drive rotational workpieces disc spins, starting evaporation source switch, and camber reflection rotates in plated film cavity, and evaporation source sprays coating materials, opens
Beginning plated film, due to being fixed with correcting plate on the technical program bracket, shark's fin coincides thereon with correcting plate for curved reflector rotation
When, to shelter from two long sides on curved reflector, the generation of coating film thickness uneven phenomenon is overcome, to improve plating
The qualification rate of film.
In the utility model unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " fixation "
Equal terms shall be understood in a broad sense, for example, it may be fixedly connected, may be a detachable connection or integrally connected, can be two
Connection inside a element.For those skilled in the art, above-mentioned term can be understood in this reality as the case may be
With novel concrete meaning.
