Plate material laser cutting device and laser cutting jig thereof

Abstract

The invention relates to a plate material laser cutting jig. The plate material laser cutting jig comprises a base plate, a magnet and a magnetic part, wherein the upper surface of the base plate comprises a cutting area and a non-cutting area, a slit is formed in the cutting area and used for laser to pass through, the width of the slit is 1.5mm to 2mm, and a groove and / or counter bore is formed in the non-cutting area; the magnet is arranged in the groove and / or the counter bore; the magnetic part is arranged above the magnet, and the magnetic part is used for fixing and compacting a to-be-cut plate material between the magnetic part and the magnet. The to-be-cut plate material is flatly fixed on the base plate by virtue of the cooperation of the magnet and the magnetic part, so that the problems such as cutting flanging, blackening and poor cutting precision caused by the roughness of the plate material can be solved. In addition, the width of the slit for the laser to pass through is 1.5mm to 2mm, by adopting the slit of the width, on one hand, the residue of smoke can be avoided, the heat nearby the slit can be radiated in time, and the problem that a product is easily partially damaged can be solved. The invention also provides a plate material laser cutting device comprising the plate material laser cutting jig.

Description

technical field [0001] The invention relates to a laser cutting device, in particular to a plate laser cutting device and a laser cutting fixture thereof. Background technique [0002] With the wide application of laser processing in all walks of life, the diversification of laser cutting equipment has become an inevitable trend. At present, flexible circuit boards (FPC) are widely used in notebook computers, tablet computers, mobile phones, PDAs, handheld GPS, digital cameras, LCD TVs, communication equipment, MP4 and other equipment, especially in important parts of electronic products. It has a wide range of applications, for example, it can be used for mobile phone keyboards, POS machine keyboards and other keyboards that require small space; the motherboard and external boards are connected, such as display screens, buttons, vibration motor boards; panel key boards, such as LCD, digital phase. The panel is equipped with a keyboard, etc. At the same time, the above prod...
