Description
Technical Field
The utility model relates to the technical field of dies for coating optical lenses, in particular to an area coating die for processing a laser projection film.
Background
With the development of science and technology, the appearance of a product is also changed, the coating of the product gradually tends to meet the requirements of two different film layers in two areas on the same surface, as shown in a product in fig. 3, the requirements of two different film layers in zoneA and zoneB in two areas need to be met on the same surface, if the photo-etching coating and the silk-screen peelable glue coating are adopted, glue residues exist, the good smoothness of the product cannot be ensured, and the laser threshold value of the product is influenced; if adopt traditional tool to shelter from the coating film, can only single regional coating film, can't realize two regions and plate different retes, the changeover portion between two regions is not controlled well moreover, causes the changeover portion edge coarse easily, and the changeover portion uncontrollable influences product quality below 0.5 mm.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
The utility model aims to provide an area coating die for processing a laser projection film, which is convenient for shielding and coating different film layers on two areas on the same surface of a lens, can control a transition section to be less than 0.5mm, and simultaneously can ensure that a product has good finish and improve the product quality. In order to achieve the purpose, the utility model adopts the following technical scheme:
(II) technical scheme
The utility model provides a regional coating film mould of laser projection piece processing usefulness, includes that the complete set is by diaphragm capsule one and diaphragm capsule two that the stainless steel made, the equidistant interval fretwork of the bottom plate of diaphragm capsule one has n bar coating film hole one, be connected with between the bar coating film hole one and shelter from strip one, the equidistant interval fretwork of the bottom plate of diaphragm capsule two has n +1 bar coating film hole two, be connected with between the bar coating film hole two and shelter from strip two, bar coating film hole two with shelter from strip one and overlap from top to bottom and correspond, shelter from strip two with bar coating film hole one overlaps from top to bottom and corresponds, bar coating film hole one and the bottom of bar coating film hole two do 45 chamfers around and handle.
Furthermore, the flatness of the bottom plates of the first mold box and the second mold box is controlled according to a middle level.
(III) advantageous effects
Compared with the prior art, the lens has the obvious advantages and beneficial effects, and particularly, different film layers can be conveniently plated on two areas on the same surface of the lens by adopting the first die box and the second die box which are separated to shield the film, the transition section can be controlled to be below 0.5mm, and meanwhile, the good finish degree of a product can be ensured, and the product quality is improved.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.
The utility model is further described with reference to the following detailed description and accompanying drawings.
Referring to fig. 1 and 2, a regional coating die for processing a laser projection film comprises a set of a first die box 1 and a second die box 2 made of stainless steel, wherein n strip-shaped coating holes 11 are hollowed at equal intervals on the bottom plate of the first die box 1, a first blocking strip 12 is connected between the strip-shaped coating holes 11, n +1 strip-shaped coating holes 21 are hollowed at equal intervals on the bottom plate of the second die box 2, a second blocking strip 22 is connected between the strip-shaped coating holes 21, the strip-shaped coating holes 21 are overlapped with the first blocking strip 12, the second blocking strip 22 is overlapped with the strip-shaped coating holes 11, and the peripheries of the bottoms of the strip-shaped coating holes 11 and the strip-shaped coating holes 22 are chamfered by 45 degrees, so that the edge effect of a vapor-coated layer is better, the coated edge is not rough, the error is small, and the edge precision is conveniently controlled, this operation enables the transition section to be controlled to below 0.5 mm. When the film coating machine is used, a film coating film plated product 3 is firstly placed into a die box 1, when a film coating layer is evaporated upwards from a strip-shaped film coating hole 11, a film layer in a zoneA area can be plated firstly, a zoneB area is blocked by a blocking strip 12 and cannot be coated, the film coating film plated product 3 is taken out from the die box 1 and placed into a die box 2 for coating, only the zoneB area can be coated at the moment, the coated film plated product after coating is shown in a figure 2, finally, a plurality of film coating films 4 are obtained by cutting along dotted lines, and qualified products are selected.
For the bottom plate of laminating diaphragm capsule one 1 and diaphragm capsule two 2 that makes the diaphragm can be better to make the coating film edge more accurate, further reduce the changeover portion, the plane degree of the bottom plate of diaphragm capsule one 1 and diaphragm capsule two 2 is according to the medium level management and control.
According to the utility model, the first die box and the second die box are adopted to separate the shielding coating, so that different coating layers can be conveniently coated on two areas on the same surface of the lens, the transition section can be controlled below 0.5mm, and meanwhile, the good smoothness of the product can be ensured, and the product quality is improved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
