Embodiment Construction
[0021] see figure 1 , 2 The shown multi-layer material masking tape for shielding and fixing around electronic devices of car navigation includes a pet unit 320 arranged on a single-sided adhesive 100 and a protective film 400 covering the pet unit. In order to realize material saving and improve product quality and production efficiency, the production method of multi-layer material masking tape is as follows.
[0022] a. see image 3 , paste the double-sided release paper 200 on the single-sided adhesive 100, die-cut on the double-sided release paper with the first die, the contour of the die-cut on the double-sided release paper by the first die is 210. see Figure 4 , 5 , the double-sided release paper part (waste material) 220 in the outline 210 is discharged to obtain the separation strip 230 pasted on the single-sided adhesive 100;
[0023] b. see Image 6 , 7 , compound the pet film 300 on the single-sided adhesive with spacer strips, and use the second knife di...

The invention provides a masking tape die cutting production method through which waste can be smoothly discharged and the production efficiency is high. A body unit in masking tape produced according to the method is high in shape and position accuracy. The masking tape comprises the body unit arranged on a single-sided adhesive, and a protection film covering the body unit. The production method includes the following steps that a, release paper is pasted to the single-sided adhesive, and die cutting and waste discharge are conducted on the release paper through a first cutting die; b, a body film is compounded on the single-sided adhesive with the release paper, die cutting is conducted on the body film through a second cutting die so that the contour of a pct unit can be obtained, and the contour of a waste material discharged in the step a is the same as the contour formed after the contour of the body unit is moved inwards by 0.6-1.5 mm to be reduced; and c, waste discharge is conducted on the body film and the release paper so that only the body unit can be reserved on the single-sided adhesive.
Description
technical field [0001] The invention relates to a production method of masking tape used on electronic equipment such as car navigation equipment and display screens. Background technique [0002] With the development of science and technology, electronic industrial tapes are becoming more and more widely used, not only for TFT-LCD, but also for automotive electronics. As one of the devices for fixing electronic devices and connecting LCD screens, electronic industrial tapes require industrial tapes to fix electronic components in car navigation equipment. The requirements for tapes are very high. They mainly play the role of fixing, shielding, shock resistance and high temperature resistance. , making the navigation device more shock-resistant and drop-resistant when in use. The masking tape is a tape with a main unit that mainly plays a masking role on the single-sided tape. [0003] The production of electronic tape mainly relies on the die-cutting method. For die-cutti...
