Description

Positioning device of polaroid fillet punching die Technical Field The utility model belongs to the technical field of die positioning, and particularly relates to a positioning device of a polaroid fillet punching die. Background The polarizer is a core optical component of a liquid crystal display module (LCD), and a specific outline is required to be formed by a precise punching process in the production process. The round corner rectangle is a common design form of the polaroid, and the round corner structure can effectively avoid edge stress concentration during screen assembly and reduce cracking risk. The process is generally realized by adopting a high-precision punching die, and the positioning precision of the die directly influences the quality of the punching edge of the polaroid. In the prior art, the die-cut mould of polaroid fillet mainly relies on the following two kinds of locate mode: Vacuum adsorption positioning, namely fixing the polaroid through a negative pressure suction hole at the bottom of the die. However, the polarizer has extremely thin thickness (usually 0.1-0.3 mm), smooth surface, and is easy to shift due to air pressure fluctuation or slight warping of materials in the adsorption process, and particularly, the lateral shearing force can aggravate position deviation when punching round corners, so that the round corners are deviated in size or burrs are caused. Mechanical clamping and positioning, namely clamping the edge of the material by adopting a lateral pushing block or a blank holder mechanism. However, mechanical contact is easy to generate indentation or scratch on the surface of the polaroid, and the clamping positions of polaroids with different sizes need to be frequently adjusted, so that the operation efficiency is low, and the flexible production requirement is difficult to adapt. The above problems lead to the following drawbacks of the existing positioning devices: the positioning stability is insufficient, namely, the vibration at the moment of punching is easy to cause the micro-displacement of the polaroid, and the round corner area is easy to have uneven cutting marks or chipping; the yield is limited, namely the rejection rate is obviously increased due to the out-of-tolerance size or appearance damage caused by positioning offset; The compatibility is poor, the positioning component is required to be debugged again when the product specification is switched, the downtime is prolonged, and the production efficiency is affected. Therefore, a positioning device for a circular bead punching die of a polaroid is needed, and the problems that positioning stability is insufficient and positioning of punching dies of different specifications is inconvenient according to machining sizes in the prior art are solved.
