Description
Technical field
The present invention relates to a kind of COF vacuum hotpressings tool and its application method.
Background technology
OCA (optical cement) is used for cementing transparent optical element, is that optics acrylic glue is made into no base material, then upper and lower
Bottom, then respectively one layer of release film of fitting, it is a kind of two-sided joint adhesive band of no matrix material.OCR (liquid optical cement) is used for
The bonding of transparent optical element, suitable for the fitting and assembling between touch screen, sized rectangular glass substrate or other rigid-flex.
However, existing laminated material OCA (optical cement), OCR (liquid optical cement) abutted equipment and tool, fitting side
Formula is bonded just for display screens such as a kind of LCD, LED, OLED, TPS of specification and can not carry out LCM display modules
Fitting.Existing OCA (optical cement) is when display screen fitting is using vacuum hot-pressing equipment fitting or OCR (liquid optical cement) is aobvious
Display screen fitting can place tool using during point glue laminating equipment in lower fitting platform, be placed when OCA (optical cement) is bonded in tool
Common silicagel pad or rubber blanket are as buffering, and tool is without rubber cushion when OCR (liquid optical cement) is bonded, during fitting once only
Monolithic product fitting can be carried out, a specification product must correspond to a tool when being bonded, OCA (optical cement) joint tool is selected
Common rubber cushion padded coaming, material is harder, and elasticity is bad, and buffering effect is not strong, and screen, xanthochromia and bubble etc. can be caused brokenly bad existing
As.The problems such as excessive glue, strike-through, ink edge do not solidify occurs when being bonded in OCR (liquid optical cement).And former laminating type without
Method carries out LCM display module fittings, the filling of the thicker product of surface frame be present.
The content of the invention
The technical problem to be solved in the present invention is：For overcome the deficiencies in the prior art, there is provided a kind of COF vacuum hotpressings are controlled
Tool and its application method, can be bonded all by jointing product within the platform size.
The technical solution adopted for the present invention to solve the technical problems is：A kind of COF vacuum hotpressings tool, the tool are main
By the frame shape module for the lower fitting platform upper surface for being fixed on COF vacuum hot-pressing equipments, it is filled in breathing freely in frame shape module frame
Foam and the exhaust screen cloth composition for being arranged on ventilative foam upper surface, four lateral surfaces of frame shape module are bonded the four of platform with lower
Four lateral surfaces of individual side alignment or frame shape module are respectively positioned on the inner side of four sides of lower fitting platform.
A kind of application method of COF vacuum hotpressings tool, is comprised the following steps that：
Step 1：Jointing product is placed on to the upper surface of exhaust screen cloth, and the lower surface for being vented screen cloth is provided with ventilative bubble
Cotton, the upper surface of jointing product are higher than the upper ledge face of frame shape module；
Step 2：When jointing product is bonded with display screen or display module, under the upper hot pressboard of COF vacuum hot-pressing equipments
Pressure, the exhaust screen cloth of upper hot pressboard lower surface is pressed onto jointing product, exhaust screen cloth and ventilative foam successively, until upper hot pressboard pressure
Close the upper ledge face of frame shape module；
Step 3：Jointing product and display screen or display module by the bounce for foam of breathing freely close to overlaying.
The beneficial effects of the invention are as follows：The tool is bonded more specification products simultaneously, and the fraction defective of product is greatly lowered, section
Human-saving, save financial resources, the overlapping investment of equipment and tool cost input；The fitting of LCM display modules is solved because surface frame thickness can not
Fill the problem of fitting；The COF applying methods can be bonded all same by jointing product, multiple products within the platform size
When fitting do not need multiple tools.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
In accompanying drawing marked as：A, lower fitting platform；B, upper hot pressboard；C, jointing product；1st, frame shape module；1-1, outside
Face, 1-2, upper ledge face, 2, ventilative foam, 3, exhaust screen cloth.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
See Fig. 1, a kind of COF vacuum hotpressings tool, just in thermoplastic optical glued membrane, the tool is mainly by being fixed on
The frame shape module 1 of the lower fitting platform a upper surfaces of COF vacuum hot-pressing equipments, the ventilative foam 2 for being filled in the inframe of frame shape module 1
Formed with the exhaust screen cloth 3 for being arranged on the ventilative upper surface of foam 2, four lateral surface 1-1 of frame shape module 1 are bonded platform a with
The alignment of four sides or frame shape module 1 four lateral surface 1-1 be respectively positioned on lower fitting platform a four sides inner side.
The thickness and width dimensions of frame shape module 1 are formulated according to the size of COF vacuum hot-pressing equipments, frame shape module 1
Hardness is higher, and fine grinding, heatproof is higher than 100 °.Ventilative foam 2 has extraordinary elasticity, decrement and flexibility, heatproof to be higher than
100°.The thickness of ventilative foam 2 is formulated according to by jointing product c thickness, typically by the upper of jointing product c
Surface can be higher than the upper ledge face 1-2 of frame shape module 1, be specifically higher by and how much formulated according to actual product.
The application method of the COF vacuum hotpressing tools, is comprised the following steps that：
Step 1：Jointing product c is placed on to the upper surface of exhaust screen cloth 3, and the lower surface for being vented screen cloth 3 is provided with
Bubble cotton 2, jointing product c upper surface are higher than the upper ledge face 1-2 of frame shape module 1；
Step 2：When jointing product c is bonded with display screen or display module, the upper hot pressboard b of COF vacuum hot-pressing equipments
Push, the exhaust screen cloth 3 of upper hot pressboard b lower surfaces is pressed onto jointing product c, exhaust screen cloth 3 and ventilative foam 2 successively, until upper
Heating platen b presses to the upper ledge face 1-2 of frame shape module 1, and the upper ledge face 1-2 of frame shape module 1 plays balance and supporting function；
Step 3：Jointing product c by the bounce for foam 2 of breathing freely to conjunction is overlayed, paste with display screen or display module
Product c is closed in the range of tool.
The exhaust screen cloth 3 of the ventilative upper surface of foam 2 and the exhaust screen cloth 3 of upper hot pressboard b lower surfaces are to preferably arrange
Gas, exhaust screen cloth 3 can prevent electrostatic, meanwhile, exhaust screen cloth 3 can be changed, avoid cull and it is dirty stick in ventilative foam 2 or
On upper hot pressboard b.
The tool can carry out different sized products fittings, while can carry out multiple products while be bonded, and solve LCM and show
Show module binding face, the filling problem of the thicker product of surface frame, solution pressure is big, and pressing plate balance, hardness is high, elastic bad, tool
Precision is uncontrollable and the problem such as more tools.This kind of laminating type is not in brokenly the bad phenomenons such as screen, xanthochromia and bubble.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
