Description
Technical field
The present invention relates to the hold down gag of a kind of lens press loader, particularly a kind of lens press loader.
Background technology
The Lens assembly of mobile phone camera camera lens, interior rule camera lens etc. need to adopt lens press loader to press-fit, the hold down gag of existing lens press loader, it all is rigid stamp, all for made the patrix drive unit by cylinder, utilize cylinder directly to drive patrix and do straight reciprocating motion to realize press-fiting of Lens assembly.This pressuring method, owing to be that rigidity is exerted pressure, and pressure is difficult for regulating. and simultaneously, because pressure rises sharply, rapid drawdown, lens set might rebound, and affects the compression of eyeglass, affects the yields of product when exerting pressure.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and a kind of uniformity coefficient that improves compaction degree when press-fiting eyeglass and compression is provided, improves the hold down gag of the lens press loader of product yields.
A kind of hold down gag of lens press loader comprises upper die and lower die and patrix drive unit, and its structural feature is: described patrix is connected on the patrix drive unit by elastic connecting device elasticity.
The patrix elasticity of lens press loader hold down gag is connected on the patrix drive unit, and the pressure that the patrix drive unit produces then acts on first on the elastic connecting device, then promotes patrix by elastic connecting device again and presses down, to realize press-fiting of Lens assembly.The hold down gag of this structure behind the patrix haptic lens, by the Bottom Runby of control patrix drive unit, just can be controlled the deflection of elastic connecting device, thus the pressure that the gradual change of control patrix strengthens.The mode of this soft pressurization is very favourable to protecting eyeglass and realizing that eyeglass compresses uniformly.
Described elastic connecting device comprises elastic component, and an end of elastic component is connected in the lower end of patrix drive unit executive item, and the other end of elastic component then directly links to each other with patrix, or links to each other with patrix by the patrix fixed mount.
Described elastic connecting device comprises elastic component, be connected with the elastic component support bar at patrix drive unit executive item, elastic component is set on the support bar, be provided with the elastic component upper support seat on the top of support bar or at patrix drive unit executive item, also be provided with elastic component lower support seat in the bottom of support bar, elastic component is arranged between upper support seat and the lower support seat, also is provided with the patrix fixed mount between elastic component and lower support seat, and patrix is installed on the patrix fixed mount.
The hold down gag of described lens press loader also includes upright slide rail, and the patrix fixed mount links to each other with slide block, and slide block is installed on can do along slide rail on the slide rail and pumps.
Patrix is determined linear movement direction with slide block and slide rail, can guarantee that the descending process of patrix is not offset, and guarantees the accuracy that presses down.
Described counterdie comprises die sheet, die socket, the die cap, the die cap is fixed in the upper end of die socket, end face at the die cap is provided be used to the through hole that holds the die sheet, the upper surface of the straight-through die socket of this through hole, the upper surface of die socket is the plane, and the die sheet is arranged in this through hole, is provided with the through hole that holds eyeglass at the middle part of die sheet.
When press-fiting Lens assembly, for the counterdie die cavity of laying Lens assembly a plane that precision is high need to be arranged.Adopt the counterdie of this structure, can wear into first a high-precision plane to the upper surface of die socket, the mode of this processing plane, can guarantee good flatness, simultaneously processing is very simple also, then the die cap being fixed on the die socket again, putting into the die sheet at last in the through hole of die cap, fits in its lower surface and die socket upper surface.
In order to be convenient for changing the die sheet, be symmetrically arranged with at the outer peripheral face of die cap and link up open slot that it is used for holding the through hole of die sheet, like this when changing the die sheet, can be directly with the instruments such as pliers thus open slot stretch into to take out the die sheet.
Described die cap is a kind of calyptra, and its cover is placed on the upper end of die socket.
Described counterdie also includes the die socket fixed head, is provided with the cavity that holds die socket on the die socket fixed head, and the shape size of this cavity is decided according to the garden post shapes size on patrix top, and the two size is clearance fit Guan Department.
So when mounted, can utilize this design feature to carry out the location that the die sheet is installed.Be exactly before dress die sheet, garden, punch top post reached the horizontal direction location that is fixed plate in the cavity of die socket fixed head, then lock die block, the die socket of packing into, cover after the die cap, refill the die sheet.
Described patrix drive unit is linear stepping motor.
The patrix drive unit also can be cylinder etc.
Utilize linear stepping motor as the patrix drive unit, just can utilize the linear stepping motor controller accurately to control the omnidistance movement velocity of patrix and distance, thus the deflection of convenient control elastic connecting device, with the pressure of control patrix.
The present invention is following advantage compared to existing technology:
The hold down gag of lens press loader of the present invention adopts the elasticity compacting, and by the deflection of control elastic component, with controlled pressure, the Lens assembly dress that can protect like this eyeglass can adapt to again different size, needs different pressures is pressed.
The present invention also arranges guide rail at patrix, utilizes guide rail to guarantee not beat of the descending process of patrix, carries out the location of vertical direction.Simultaneously the present invention also arranges the cavity that is clearance fit Guan Department with garden, patrix top post at the die holder of counterdie, utilizes when mounted this cavity that die is positioned, thereby guarantees upper and lower mould location in the horizontal direction.
The present invention is also by arranging the unique texture counterdie, thereby can change flexibly the die sheet according to the needs of eyeglass easily.
The present invention utilizes stepper motor to exert pressure, and advantage is to utilize controllor for step-by-step motor can control omnidistance movement velocity and the accurate size of controlling travel distance and exerting pressure.
