Abstract

The utility model discloses a kind of alignment device of backlight module kludge, including base, loop bar, sucker, sleeve；The both sides of described base are separately installed with loop bar, and the both sides of sucker are separately installed with sleeve, and the sleeve of sucker both sides is relative with the loop bar of base both sides respectively and sets, and sucker is actively socketed on loop bar by sleeve and can moved up and down along loop bar.Because original sucker size is extended out increasing by the utility model and increase sleeve is set in the left and right sides, original base dimensions are extended out into increasing and increase loop bar is set in the left and right sides, sucker is actively socketed on loop bar by sleeve and can moved up and down along loop bar, robot drives sucker draws shading rubber belt and drives the left and right sides loop bar of left and right sides sleeve and base on sucker to connect together up and down, so pass through the correction of sleeve and loop bar, it is accurate to ensure that base coordinates with sucker, there is the advantages of high assembly precision, improvement bright border.

Description

The alignment device of backlight module kludge

Technical field

The manufacture field of backlight module is the utility model is related to, the contraposition more particularly to a kind of backlight module kludge fills Put.

Background technology

As shown in Figure 1A, existing backlight module 10 assembles shading rubber belt 20, brightening piece, diffusion sheet, the board of reflector plate Contraposition uses contactless contraposition.Assembled machine table alignment mode uses contactless contraposition, is confined to the motor of mechanical arm The limitation of precision and the pneumatic method of operation, the positional repeatability in the mechanical arm running of existing assembled machine table> 0.10mm, precision>It is difficult the mobile phone backlight module or tablet personal computer backlight module pair for meeting current ultra-narrow frame that 0.10mm, which is, In shading rubber belt, brightening piece, diffusion sheet, reflector plate assembling demand, particularly shading rubber belt assembling requirement.Present hand The screen frame of machine/tablet personal computer is more and more narrow, this cause the shading rubber belt of backlight module and the superiors' diaphragm (above add lustre to or on Diffusion) paste width（A sizes）Design load it is less and less, as shown in Figure 1 and Figure 2, if a is closely sized to or less than group The limit of accuracy of installation platform, in actual production process, in fact it could happen that for a values close to 0 situation, such backlight module 10 will It is bad to produce bright border/bright line, if a sizes<0, i.e., shading rubber belt 20 be not attached to add lustre to or upper diffusion on, backlight module 10 is just Be not closed, it is internal easily to enter steam, produce bright border/bright line it is bad cause backlight module 10 performance it is bad and have a strong impact on Service life.The backlight module positioning mechanism commonly used includes sucker 1 ', base 2 ', and sucker 1 ' adsorbs shading rubber belt 20 and is fitted in bottom On backlight module 10 on seat 2 ', due to sucker 1 ' with base 2 ' without guiding mechanism, the patch of shading rubber belt 20 and backlight module 10 It is inaccurate to close contraposition.

In view of this, the design people for backlight module kludge aligning structure design on do not attain improve caused by it is all More missings and inconvenience deeply design, and actively research improvement has a fling at and develops and design the utility model.

The content of the invention

The purpose of this utility model is to provide that a kind of assembly precision is high, improves the contraposition of the backlight module kludge of bright border Device.

To achieve the above object, technical solution of the present utility model is：

The utility model is a kind of alignment device of backlight module kludge, including base, loop bar, sucker, sleeve；It is described The both sides of base be separately installed with loop bar, the both sides of sucker are separately installed with sleeve, the sleeves of sucker both sides respectively with base The loop bar of both sides is relative and sets, and sucker is actively socketed on loop bar by sleeve and can moved up and down along loop bar.

Described sleeve uses innerspring high-accuracy alloy ball jacket, and loop bar uses high-accuracy alloy loop bar.

The utility model also includes manipulator；The described side for including manipulator and being arranged on base, sucker are fixedly mounted on The free end of manipulator.

After such scheme, because original sucker size is extended out increasing by the utility model and is set in the left and right sides Increase sleeve, original base dimensions are extended out into increasing and increase loop bar is set in the left and right sides, sucker passes through sleeve movable sleeve It is connected on loop bar and can be moved up and down along loop bar, robot drives sucker draws shading rubber belt and drives the left and right sides on sucker to cover The left and right sides loop bar of cylinder and base connects together up and down, so by the correction of sleeve and loop bar, ensure that base with inhaling Disk coordinates accurate, and motor is adversely affected to caused by precision with the pneumatic method of operation and is reduced to minimum, avoids manipulator The problem of repeatable accuracy difference, reach backlight module assembly precision≤0.10mm requirement, solve ultra-narrow frame backlight module Bright border bright line caused by packaging technology low precision, enter the problems such as steam, have that assembly precision is high, improves the advantages of bright border.

The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.

Embodiment

As shown in Figure 3, Figure 4, the utility model is a kind of alignment device of backlight module kludge, including base 1, loop bar 2nd, sucker 3, sleeve 4, manipulator 5.

The described side for including manipulator 5 and being arranged on base 1, sucker 3 are fixedly mounted on the free end of manipulator 5.

The both sides of described base 1 are separately installed with a loop bar 2, and the both sides of sucker 3 are separately installed with a sleeve 4, The sleeve 4 of the both sides of sucker 3 is relative with the loop bar 2 of the both sides of base 1 respectively and sets, and sucker 3 is actively socketed on loop bar 2 by sleeve 4 It can move up and down above and along loop bar 2.

Described sleeve 4 uses innerspring high-accuracy alloy ball jacket, and loop bar 2 uses high-accuracy alloy sheath Bar.

Operation principle of the present utility model：

With reference to shown in Figure 1A, manipulator 5 drives sucker 3 to draw shading rubber belt 20 and drives left and right sides sleeve 4 on sucker 3 Connect together about 2 with the left and right sides loop bar of base 1, so inhaled by the correction of sleeve 4 and loop bar 2, the driving of manipulator 5 Disk 3 is pushed, and shading rubber belt 20 and backlight module 10 are assembled up.

Emphasis of the present utility model is that：Provided with the guiding mechanism being made up of loop bar, sleeve.

It is described above, only the utility model preferred embodiment, therefore the utility model implementation can not be limited with this Scope, i.e., the equivalent changes and modifications made according to present utility model application the scope of the claims and description, it all should still belong to this reality In the range of being covered with new patent.
