Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The holographic patterns of various products are different, and if the anti-counterfeiting holographic positioning paper is positioned only by the holographic patterns in the manufacturing process, the deformation quantity of the anti-counterfeiting holographic positioning paper is difficult to detect, and the dimensional accuracy is difficult to control. Therefore, the invention provides a positioning frame applied to anti-counterfeiting holographic positioning paper and a preparation method thereof, wherein the positioning frame is photoetched to a nickel plate and is impressed on a coating along with a holographic pattern; whether the holographic pattern is deformed or not or the size of the holographic pattern does not reach the standard can be measured by utilizing the positioning frame; the mould pressing process and the composite process are key processes, the precision of the product is controlled by the two processes, and the two processes need to adopt positioning frames for control.
Example 1
As shown in fig. 1, this embodiment provides a location frame of anti-fake holographic positioning paper, and it sets up on the nickel version, shifts to anti-fake holographic positioning paper through the mode of mould pressing on, includes: the device comprises a rectangular frame, cursor blocks, tracking lines, corner lines and gauge lines;
the rectangular frame is used for judging whether the anti-counterfeiting holographic positioning paper is deformed, and when the four corners of the anti-counterfeiting holographic positioning paper are not right angles, the anti-counterfeiting holographic positioning paper is judged to be deformed;
specifically, according to the characteristics of a rectangle, a parallelogram with one corner being a right angle is ensured to be a rectangle; in the production process, whether the anti-counterfeiting holographic positioning paper is deformed can be judged only by detecting whether one corner is a right angle; other figures, such as circles, diamonds and the like do not have the characteristic and cannot be used as positioning frames;
the cursor blocks are distributed on two sides of the same side of the rectangular frame and used for positioning the rectangular frame and changing the deformation of the anti-counterfeiting holographic positioning paper;
specifically, because the common PET base film is still in a transparent state after being coated, in the practical application process, the rectangular frame can only identify that the anti-counterfeiting holographic positioning paper is deformed, but the specific deformation degree cannot be obtained; the cursor block is solid and is displayed as white after being molded on the base film with the coating, and the cursor block is easy to identify because the PET base film and the coating are transparent, so that the size of deformation can be easily observed by naked eyes based on the cursor block, and the precision of the anti-counterfeiting holographic positioning paper is easy to regulate and control; in addition, the cursor block also plays a role in electric eye recognition in each process of preparing the anti-counterfeiting holographic positioning paper, and aims to detect the stability of the plate distance;
specifically, the cursor blocks are solid rectangles, are positioned on the same side of the rectangular frame and are distributed on two sides, are 5-60 mm long and 3-10 mm wide, and are used for clearly identifying whether the holographic anti-counterfeiting positioning paper is distorted in the production process, so that the positioning accuracy of the rectangular frame is ensured;
the corner lines are positioned on the upper surface of the rectangular frame and correspond to four corners of the rectangular frame, each corner line comprises a single corner line or a plurality of corner lines and is used for positioning the image position and detecting deviation values of upper, lower, transverse, left, longitudinal and right longitudinal directions of the image;
specifically, the angular lines are positioned at four corners of the rectangular frame, each angular line is in a right-angle shape and is perpendicular to the rectangular frame, usually, one or more angular lines are arranged at each position, each angular line is unlimited in length, and the width is 0.1 mm-0.3 mm; in practical application, the outermost frame of the laser holographic pattern is aligned with the innermost frame of each corner line, when the laser holographic pattern is an irregular pattern, the deformation quantity of the laser holographic pattern is not easy to be accurately measured, and at the moment, the specific deviation value of the laser holographic pattern can be obtained only by measuring the deviation of the corner line aligned with the outermost frame of the laser holographic pattern, so that the dimensional accuracy can be ensured when each procedure is subjected to dimensional adjustment, and the precision is ensured to be +/-0.15 mm;
the tracking line is positioned on one side of the rectangular frame intersected with one side with the cursor block and is used for performing deviation rectifying tracking on the anti-counterfeiting holographic positioning paper to ensure that the anti-counterfeiting holographic positioning paper is in the same horizontal position; the length of the tracking line is greater than the side length of the rectangular frame;
specifically, the tracking line is parallel to one side of the rectangular frame, is intersected with one side of the rectangular frame with the cursor block, is longer than the rectangular frame, has the width of 1-5 mm, and is used for performing deviation rectifying tracking on the anti-counterfeiting holographic positioning paper to ensure that the anti-counterfeiting holographic positioning paper is in the same horizontal position;
when no positioning frame or tracking line exists, the equipment is subjected to deviation rectification and tracking by a film edge or a paper edge, so that the condition of losing marks due to fluctuation is easy to occur, and defective products can be generated due to poor stability; the design of the tracking line has a certain width, and the deviation correcting and tracking device is easy to recognize and track, so that the stability of the product can be ensured;
the gauge lines are positioned on the side of the optical cursor block and the side of the tracking line of the rectangular frame and are arranged in a step shape, the gauge line positioned in the middle is superposed with the rectangular frame, and the rest gauge lines are parallel to the rectangular frame and are used for evaluating the squareness of a transverse cutting process in the preparation of the anti-counterfeiting holographic positioning paper; even if a square is not used for measurement, whether the cutting of the anti-counterfeiting holographic positioning paper is standard or not can be judged by observing the gauge line during inspection;
specifically, as shown in fig. 2, the gauge lines are located on both sides of the rectangular frame, namely: one side with cursor block and one side with tracking line; 1-5 groups of gauge wires exist on each side, and 3-15 gauge wires exist in each group; each grain is 0.1 mm-0.3 mm thick; each group of gauge lines are arranged in a ladder shape, the length is not limited, the gauge line in the middle is superposed with the rectangular frame, and the other gauge lines are parallel to the rectangular frame; the number of each group of gauge lines is the same for the same corresponding surface of each rectangular frame, the precision of a transverse cutting process in the preparation of the anti-counterfeiting holographic positioning paper is mainly detected, and the paper squareness is usually controlled to be less than 0.5 mm.

the imaging release layer has three characteristics: the PET film has certain binding force, good printing adaptability and hardness which can adapt to specific mould pressing;
the softening point of the coating resin is about 140 degrees generally, and the coating resin is used as a carrier of a die pressing information layer and is suitable for die pressing laser effect;
for the selection of the base film, only a PET film can be used as positioning paper in the prior art;
(2) and (3) a die pressing procedure:
the die pressing is a technological process of impressing laser holographic patterns on the nickel plate onto the resin coating by utilizing the thermal change performance of the chemical coating; the laser pattern is generated, the mould pressing process is not separated, and the key process of positioning the finished film is also influenced by the mould pressing;

(3) an aluminum plating process:

at present, media such as aluminum, zinc sulfide and the like are adopted for evaporation, other metals with metallic luster can be evaporated theoretically, but from the aspects of economy and stability, aluminum and zinc sulfide are most used at present;
(4) slitting:
the aluminizer is cut on a cutting machine according to the product specification, the defective films can be removed while the required specification of the film products is ensured, and the quality of the finished film is ensured; the working procedure is not only a production working procedure but also an inspection working procedure;
(5) a compounding procedure:
coating a water-based adhesive on the surface of the aluminizer and compounding and drying the aluminizer with base paper according to the position of an angle line and a tracking line on the aluminizer, wherein the step is to transfer a laser information layer on a film product to the base paper;
it should be pointed out that in the prior preparation of the anti-counterfeiting holographic positioning paper, a deviation-rectifying tracking device is also arranged on the equipment, but the equipment is usually used for tracking the edge of the PET film or the edge of paper, so that the label is easily lost due to the fluctuation of the edge of the PET film or the edge of paper, the stability is not good, and the qualification rate of film products is low; in the embodiment, the tracking line is designed on the nickel plate and is molded on the PET film, and has a certain width, so that the tracking line is very easy to identify and can ensure the stability of the film product;
if the positioning composite paper is prepared, directly carrying out a transverse cutting process;
if the positioning transfer paper is prepared, the PET film needs to be peeled off and then the transverse cutting process is carried out;
