Description
Technical field
The utility model relates to optical imaging fields, and in particular to a kind of lens assembling platform.
Background technique
Lens module is assembled by lens barrel and optical module, and optical module can be eyeglass, distance piece or optical filter, mirror
The assembling station of head module is that optical module is installed in camera lens, and it is fixed that existing assembly platform is combined by multiple locating pieces
Position, multiple locating pieces splice and combine into a limit hole for placing lens barrel, each locating piece can adjusting position, but optics
The precision and stability of component assembly are only the emphasis of assembling, and the flatness after multiple locating piece combinations is it is difficult to ensure that consistent, meeting
Lead to rigging position deviation, and is installed using preceding needing to find accurately symmetrical centre, the position meeting of locating piece after a period of use
Different degrees of change occurs, also results in installation deviation, influences the yield of lens assembling.
Utility model content
The utility model overcomes existing defect to provide a kind of lens assembling platform, reduces building block, avoids different components
Between influence of the flatness difference to assembling.
The utility model is achieved through the following technical solutions:
Lens assembling platform, including pedestal and fixed plate, the fixed plate are fixedly connected on pedestal, and fixed plate is equipped with
The positioning through hole of lens barrel is accommodated, the top surface of the pedestal is equipped with the negative pressure hole of multiple absorption lens barrels, and the negative pressure hole is located at described
For positioning through hole in the drop shadow spread on the base top surface, the inside of the pedestal is equipped with the negative pressure being connected to the negative pressure hole
Chamber, the pedestal are equipped with an air inlet being connected to the negative pressure cavity.
Further, the top surface of the pedestal is equipped with avoid holes, and the center of circle of the avoid holes and the positioning through hole is conllinear.
Further, the negative pressure hole is four, and the line of centres of four negative pressure holes is rectangle, and the diagonal line of the rectangle is handed over
Point is conllinear with the center of the avoid holes, and four negative pressure holes are corresponding with the lower edge of lens barrel.
Further, the positioning through hole is the circular through hole for being provided with the fixed plate center, the positioning through hole it is straight
Diameter is at least more than barrel outside diameters 0.01mm.
Further, the fixed plate is fixedly connected with the base by the bolt on four angles.
Compared to the prior art the utility model has the advantage that
The utility model is formed by one piece of fixed plate and a pedestal fixation, and component is few, and the flatness of assembly is easy to protect
Card, for the positioning through hole at fixed plate center for accommodating lens barrel, positioning through hole can tentatively limit the position of lens barrel, negative on pedestal
Lens barrel is firmly adsorbed on pedestal by pressure hole, and preventing the pressure of installation to be applied on lens barrel moves lens barrel in positioning through hole
Dynamic, the optical module that avoid holes can be avoided installation touches base body, prevents optical module from damaging.Without manual adjustment portion
Part clamping, service precision, which not will receive artificial adjusting, to be influenced.
Detailed description of the invention
Fig. 1 is the utility model perspective view of the explosion.
Fig. 2 is the utility model overall schematic.
Specific embodiment
Lens assembling platform as shown in Figure 1, 2, including pedestal 1 and one piece of fixed plate 2, the fixed plate 2 are fixedly connected
On pedestal 1, fixed plate 2 is equipped with the positioning through hole 3 for accommodating lens barrel, and lens barrel is placed in positioning through hole when use, and lens barrel is whole
It is supported by pedestal, positioning through hole Primary Location lens barrel prevents it to be displaced any movement in the horizontal plane.The top surface of pedestal 1 is equipped with
The negative pressure hole 4 of multiple absorption lens barrels, negative pressure hole 4 are located at the positioning through hole 3 in the drop shadow spread on 1 top surface of pedestal,
The inside of the pedestal 1 is equipped with the negative pressure cavity that is connected to the negative pressure hole 4, and negative pressure cavity in the accompanying drawings and is not drawn into, and structure is
The chamber that chassis interior is separately provided, four negative pressure holes are straight down with the chamber, and pedestal 1 is equipped with one and institute
The air inlet 6 of negative pressure cavity connection is stated, air inlet 6 can also be connected in the side of pedestal in other positions, the blowing system in workshop
Negative pressure is provided to entire platform on air inlet, forms a negative pressure region at negative pressure hole, camera lens is placed on negative pressure hole and is born
Firm absorption is fastened, prevents lens barrel when assembling from being moved horizontally by the influence generation of the external force assembled, leads to lens barrel lower edge and bottom
Friction between seat causes adverse effect to etched surface.
In the present embodiment, the top surface of pedestal 1 is equipped with avoid holes 7, and avoid holes 7 are conllinear with the center of circle of positioning through hole 3, avoid holes
Diameter be positioning through hole half, the eyeglass for the bottom installed on lens barrel is that the center of convex lens then eyeglass can be different degrees of
Stretching lens barrel lower end surface, the part that avoid holes can be avoided stretching encounters base top surface, guarantees that eyeglass is not damaged.
Negative pressure hole 4 in the present embodiment is four, and the line of centres of four negative pressure holes 4 is rectangle, the rectangle it is diagonal
Line intersection point is conllinear with the center of the avoid holes 7, and four negative pressure holes 4 are corresponding with the lower edge of lens barrel, such four negative pressure
Hole is capable of providing uniform and stable negative pressure, it is ensured that lens barrel absorption is stablized.
Positioning through hole 3 is the circular through hole for being provided with fixed plate center, and the diameter of the positioning through hole 3 is at least more than lens barrel
Outer diameter 0.01mm., lens barrel is placed on the position that positioning hole combination negative pressure hole can be completely fixed lens barrel, prevents to be displaced.Gu
Fixed board 2 is fixedly connected by the bolt 8 on four angles with the pedestal 1, and fixed form is reliable and stable.
