Description

Manufacture and method of a new type of regular point damage sheet marking die-cutting process for brightness enhancement film

technical field

The invention relates to the field of die-cutting processing of a brightness enhancement film, in particular to a new type of brightness enhancement film regular spot damage sheet marking die-cutting process and method.

Background technique

With the continuous development of liquid crystal display technology, the application fields of liquid crystal displays, especially color liquid crystal displays, are also constantly expanding. Prism film is the most widely used brightness enhancement product today. (Also known as enhancement film) It is suitable for liquid crystal display modules of various sizes ranging from mobile phone display screens to liquid crystal displays. Prism film is used in almost all LCD backlights. Prism film is a layer of transparent plastic film with a thickness between 50 and 300 microns, and the upper surface of the film is evenly and neatly covered with a layer of prism structure. The prism film is placed between the diffuser of the backlight and the liquid crystal panel. Its function is to improve the angular distribution of light. It can converge the light emitted from the diffuser to the axial angle, that is In the front viewing angle, the axial brightness is improved without increasing the total output luminous flux.

In the manufacturing process of prism film raw materials, there are many processes, which will inevitably cause white spots, scratches, concave and convex spots, etc. Raw material wastage.

Contents of the invention

The technical problem to be solved by the present invention is to provide a new type of regular spot-damaged sheet of gloss-increasing film that can be used to select qualified products by marking and die-cutting. Mark die-cutting process manufacturing and methods.

The present invention is achieved through the following technical solutions: a new type of light-increasing film regular spot damage sheet marking die-cutting process and method, the specific method is as follows:

(1) Prepare a roll of light-enhancing film with spot damage, place the light-enhancing film on the die-cutting machine, and draw ten spot-mark lines on the light-enhancing film through IQC to find the spot damage;

(2) Use a film ruler or a digital display caliper to accurately measure the distance between the point damage and the point damage, and mark it on the enhancement film material with a brush;

(3) When operating on the machine, reconfirm the distance between the point damage and the point damage. There is a centering red line marked in the middle of the knife die, and the light-enhancing film is penetrated into the die-cutting machine to make the centering red line on the knife die Align with the marked point damage line, set two parallel marking blades at the lower end of the die, and the point damage line is located between the two marking blades;

(4) The operator sets the parameters of the operation panel of the die-cutting machine according to the spot damage distance, sets the jump distance and uses the 40 die to mark the process;

(5) Start marking. During the marking process, you must check at 50 meters to see which side of the two marking points the point damage line is on. The marking is formed by pressing two marking blades;

(6) If the point damage line is found to be offset, it can be corrected through the operation panel at this time to ensure that the point damage line is located between the two marks;

(7) The correction method is that if the position of the spot damage is close to the front mark, a correction compensation is made to the die-cutting machine, and the correction value is a negative number. Number, parameter correction through the operation panel, after the correction is completed, continue to turn on the die-cutting machine to mark until the point damage line is between the two marks, the area between the point damage line and the marks at both ends is the point damage range;

(8) Set the parameters according to the jump distance of the product, and then start stamping the product. The product is die-cut by the die-cutting machine. The shape and size of the product are the same. There are bad products with knife marks and qualified products without knife marks;

(9) Manually select defective products with knife marks, which are defective products if the knife marks are printed on the product, and select qualified products without knife marks.

The beneficial effects of the present invention are: the present invention marks the light-increasing film with spots, removes the marked light-enhancing film through normal die-cutting, and then selects unmarked qualified products, which can greatly improve the use of raw materials and greatly Enhance the company's interests.
