Description
Technical field
The present invention relates to a kind of production of COF winding and transport methods, belong to COF production technical field.
Background technique
The prior art, in coating, due to having gone out sprocket hole, photoresist has certain mobility, can be flowed into chain
In wheel bore, lead to the in uneven thickness of photoresist, meanwhile, contamination of products is caused at the back side that photoresist flows to COF winding.So being
Avoid such defect, dispensing area will be surveyed in the sprocket hole of two sides when coating photoresist, avoid the region of sprocket hole.
But although the influence that photoresist is flowed into sprocket hole can be reduced by doing so, photoresist has certain
Mobility causes route uneven, causes product defects it is possible to being flowed into sprocket hole；In addition the area of coating photoresist
Domain becomes smaller, and sprocket wheel bore region slatterns completely, does so and will cause a large amount of cost waste.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of production of COF winding and transport method, to
Solve the problems, such as above-mentioned background technique.
To achieve the goals above, the technical solution adopted by the present invention is that: a kind of production of COF winding and transport method,
The following steps are included: step 1: preparing one layer of insulating substrate；Step 2: one layer of conductor on sputter on the insulating substrate of preparation
Layer；Step 3: being coated with a layer photoresist in conductor layer, is exposed, develops later, etching and form line pattern, then
Carry out printing solder resist；Step 4: selection driving idler wheel mode drive and then is removed after COF winding production comes out
Fortune.
Further, insulating substrate is flexible film-like material in the step one.
Further, the material of conductor layer is copper in the step two.
Further, it is specially that the mode of idler wheel and pinch roller is driven that idler wheel mode is driven in the step four；Institute
The lower position of COF winding is arranged in the idler wheel stated；The position of the both sides of the edge 1-2mm of COF winding is arranged in the pinch roller.
Further, the pinch roller is designed using cam.
Further, the position of the idler wheel roll-in is not coated with photoresist.
Further, the cam is designed in the two sides of COF winding.
Further, the coating production method of the step three is by paste polymer, molten polymer or polymerization
Object melt is coated on paper, cloth, composite material (film) is made on plastic film.
The beneficial effects of the present invention are: the direct coating photoresist on insulating substrate, does not stamp out sprocket hole, coating
Photoresist will not flow to the back side of product by sprocket hole, and the thickness of photoresist is uniform, so the line pattern after etching is equal
Even；In addition, eliminating sprocket hole process, the process for reducing manufacture shortens the period of manufacture, reduces the cost of manufacture.

Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, below by accompanying drawings and embodiments, to this
Invention is further elaborated.However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention,
The range being not intended to restrict the invention.
Unless otherwise defined, all technical terms and scientific terms used herein are led with technology of the invention is belonged to
The normally understood meaning of the technical staff in domain is identical, and term as used herein in the specification of the present invention is intended merely to retouch
State the purpose of specific embodiment, it is not intended that in the limitation present invention.
As shown in Figure 1, Figure 2 and Figure 3, a kind of production of COF winding and transport method, comprising the following steps: step 1: quasi-
Standby one layer of insulating substrate；Step 2: one layer of conductor layer on sputter on the insulating substrate of preparation；
Step 3: being coated with a layer photoresist in conductor layer, is exposed, develops later, etching and form line pattern, then
Carry out printing solder resist；Step 4: selection driving idler wheel mode drive and then is removed after COF winding production comes out
Fortune.
Insulating substrate is flexible film-like material in the step one.
The material of conductor layer is copper in the step two.
It is specially that the mode of idler wheel 1 and pinch roller 2 is driven that idler wheel mode is driven in the step four；The idler wheel
1 is arranged in the lower position of COF winding 3；The position of the both sides of the edge 1-2mm of COF winding 3 is arranged in the pinch roller 2.
The pinch roller 2 is designed using cam.
The position of 1 roll-in of idler wheel is not coated with photoresist.
The cam is designed in the two sides of COF winding 3.
The coating production method of the step three is to be coated with paste polymer, molten polymer or molten polymer
In composite material (film) obtained on paper, cloth, plastic film.
When producing COF winding 3, as shown in Figure 1, one layer of copper of sputter first on flexible, film-form insulating substrate
Conductor layer, a layer photoresist is coated in conductor layer, is exposed, develops later, etching and form line pattern, then carrying out
Print solder resist, electrotinning.During production because when roll-to-roll production model, the not presence of sprocket hole, so
The conveying of product is mainly the idler wheel of driving portion to drive, so needing to install a certain number of driving rollings in the equipment of production
Wheel is to transport product.
Driving roller section is driven using the mode of idler wheel 1+ pinch roller 2, as shown in Figures 2 and 3, pinch roller 2 pressures
In the position of the 1-2mm at the edge of COF winding 3.When conveying, pinch roller 2 pushes down the two sides of product, and the driving idler wheel 1 of downside is removed
Send product.The pinch roller 2 of upside prevents from generating buckling phenomena in the process of running, the two of insulating substrate using the design of cam
The position of side, idler wheel roll-in is not coated with photoresist, prevents counter be sticked to of photoresist from causing weighing wounded and scratching for product on idler wheel.
This conveying mode is equally applicable in the production process of COF winding and completes the encapsulation work after COF winding production
Sequence.
The direct coating photoresist on insulating substrate, does not stamp out sprocket hole, and the photoresist of coating will not pass through sprocket wheel
Hole flows to the back side of product, and the thickness of photoresist is uniform, so the line pattern after etching is uniform；In addition, eliminating chain
Wheel bore process, the process for reducing manufacture shorten the period of manufacture, reduce the cost of manufacture.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within mind and principle.
