Technical field
The invention is related to electronic equipment production and processing technical field, in particular to a kind of gum for screen bonding
Part and its production technology.
Background technique
Nowadays, the development of handset touch panel and liquid crystal display increasingly obtains public popularize.Touch screen (Touch
Panel) refer to when finger touches Sensor, have analog signal output, analog signal is converted into calculating by controller
Machine acceptable digital signal, then integrate each component via the touch-control driver in computer and compile, finally blocked by display
Output screen signal shows touched position on the screen.It can be distinguished according to the difference for constructing and sensing form are as follows: resistance
Formula touch screen, capacitive touch screen, acoustic wave touch screen, optical touch screen, electromagnetical type touch screen.It is most general at present to be
The controller transmitted using the port USB, the function of controller is that the analog signal for being sent Sensor is converted to digital news
Number, then go to differentiate via driver, it can accomplish various change using the various Design and Features increases of touch-control driver,
Such as present it is multi-lingual facilitate client to use, increase handwriting identification function, the branch of the support of multi-screen system, computer game
Hold etc..To make among touch screen (Touch Panel) and LCD by touch screen (Touch Panel) and LCD quick assembling
It is bonded with a kind of double faced adhesive tape (being referred to as gum part in the industry).Multiple phases are used currently, generally requiring between LCD and touch screen
The gum part mutually separated connects, and is in the industry usually with tweezers respectively to be torn the gum auxiliary material of this multiple gum part from release film
Get off, then contraposition pastes on the corresponding position of LCD screen, then in the release film for tearing gum auxiliary material another side off, finishes this
Technique.Although this technique is simple, need to be bonded respectively repeatedly, it is low not only result in production efficiency, but also exists viscous
The problem of connecing malposition.
Summary of the invention
The purpose of the invention is to avoid above-mentioned shortcoming in the prior art and provide one kind and do not need repeatedly

The bonding force of gum auxiliary material piece is less than the bonding force of second release film and gum auxiliary material piece.
Wherein, the gum auxiliary material piece is provided with location hole.
Wherein, first release film is provided with grips.
A kind of technique producing the above-mentioned gum part for screen bonding is also provided, comprising:
Blanking process: gum auxiliary material piece is punched into auxiliary material sheet material；
Composition step: gum auxiliary material piece is placed in jig, and each jig includes at least two auxiliary material piece positions, Mei Gefu
A gum auxiliary material piece is placed in tablet position, and the top surface of all gum auxiliary material pieces is in same level in jig；
Overlay film step: adhesive glue is coated in the top surface of all gum auxiliary material pieces, the second release film is then covered in back
The top surface of glue auxiliary material piece, so that the top surface of all gum auxiliary material pieces is bonded in second release film；
Demoulding step: by the second release film stripping jig, all gum auxiliary material pieces is made to be detached from jig；
Secondary overlay film step: adhesive glue is coated in the bottom surface of all gum auxiliary material pieces, then covers the first release film
In the bottom surface of gum auxiliary material piece, so that the bottom surface of all gum auxiliary material pieces is bonded in first release film.
Wherein, the blanking process also goes out location hole in each gum auxiliary material piece；
In the composition step, each auxiliary material piece position of jig is provided with and the matched positioning column of location hole.
The invention the utility model has the advantages that the gum part of the invention includes multiple gum auxiliary materials, and all gums are auxiliary
The bottom surface of tablet is bonded in first release film, and the top surface of all gum auxiliary material pieces is bonded in second release film,
The bonding force of first release film and gum auxiliary material piece is less than the bonding force of second release film and gum auxiliary material piece, uses
When, it is only necessary to by the first release film stripping gum auxiliary material piece, all gum auxiliary material sector-meetings are fitted on the second release film, at this time
All gum auxiliary material pieces can be disposably adhered to on bond, then remove again by the second release film of grip
The problem of two release films, avoid low efficiency caused by multiple bonding process, position inaccurate.
Detailed description of the invention
The invention is described further using attached drawing, but the embodiment in attached drawing is not constituted to the invention
Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached
Figure obtains other attached drawings.
