Description

Technical Field

[0001] The invention relates to the technical field of die-cutting, and in particular to a tooling for cutting a release film and a use method thereof. Background Art

[0002] A release film refers to a film with a distinguishable surface. The release film has no stickiness or is slightly sticky when in contact with specific materials under limited conditions.

[0003] With the rapid development of the die-cutting industry, the processing of electronic raw materials is becoming more and more important, and the requirements for precision and cleanliness are becoming more and more stringent. The previous slitting method was to use a saw blade to slitting. The whole material was fixed on the feed shaft, and the open end of the material was passed through the slitting platform and fixed on one end of the receiving shaft. Fix the slitting saw blade on the slitting platform and start the machine.

[0004] In the microscopic environment, all cutting and chipping are ways of squeezing the material by pressure. Limited by the physical cutting method, the cut of the material will have shavings and unevenness. Since the saw blade used is also working in motion, the tolerance of the material moving from the feed shaft to the receiving shaft will be within 0.15mm.

[0005] The heating wire itself has the ability to withstand high temperatures and generate a lot of heat, and is often used for heating, while the resistance wire is not used for heating. At present, the main materials commonly used for heating wires are various metals, including nickel-chromium wire, iron-chromium wire, pure nickel wire, constantan wire, manganese copper, monel, etc.

[0006] When current passes through a resistor, it consumes electrical energy and generates heat, which is called thermal effect. After a lot of practice, it is concluded that the heat generated by current passing through a conductor is directly proportional to the amount of current itself, the resistance value of the conductor's own material, and the time value of the current flowing. The people who came to this conclusion were the British scientist Joule and the Ross scientist Lenz, so this conclusion is generally called Joule's law and Lenz's law.
