Drawings

The present invention will be further described with reference to the accompanying drawings and specific embodiments, wherein:

FIG. 1 is a schematic structural view of a punching die according to a preferred embodiment of the present invention;

FIG. 2 is a sectional view H-H in FIG. 1;

fig. 3 is a partially enlarged view of a portion a in fig. 1.

Detailed Description

The following further describes the embodiments of the present invention. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1-3, a die cutting die for optical cement includes a carrier 2 and a cutter 3 disposed on the carrier 2, where the cutter 3 includes two linear cutters disposed in parallel, the carrier 2 is further provided with a cutter slot 5, the cutter 3 is disposed in the cutter slot 5, and lubricating oil can be introduced into the cutter slot 5, so as to facilitate maintenance of the cutter 3. The bearing piece 2 is further provided with a marking piece, and the marking piece is arranged at one end of the extension direction of the cutter 3. The marking piece can generate inspection marking points on the optical adhesive, so that the efficiency of inspecting whether the size of the optical adhesive is qualified by quality inspection personnel is improved.

Further, the marking piece comprises two positioning knives, and a straight line defined by the two positioning knives is perpendicular to the extending direction of the cutting knife. The marker further comprises an identification double knife 4, and the central axis of the identification double knife 4 is in the same straight line with the positioning knife. The extending direction of the cutting knife 3 is consistent with the optical cement conveying direction. After the optical cement is punched by the punching cutting die, the waste materials on the left side and the right side are cut off by the cutter 3, specifically, the cutting depth of the cutter 3 to the optical cement can be controlled, so that the cutter 3 cuts off the release layer and the glue layer on the lower part of the optical cement, and the bottom membrane on the lower part is half cut, thereby ensuring that the glue layer is completely cut off; and the positioning knife punches two positioning points on the positioning knife, the optical cement is cut into a single product with fixed length in the following process according to the actual requirement, the positioning points cut by the positioning knife are used for positioning and cutting straight lines, the slicing machine slices at the positions of the positioning points, the identification double knife 4 can also cut two parallel identification knife lines on the product, the identification double knife 4 is added to set the distance between 2 knife lines and match the tolerance of the product, thus, 1 identification knife line is arranged on each edge of the product 2, and the size of the product can be judged to be OK if the single product has 2 identification knife lines after being sliced by the slicing machine. The distance between 2 identification knife lines can be reduced to meet the quality assurance of higher precision requirements. The defect of insufficient precision of equipment is made up through the design of the die. Meanwhile, visual judgment standards are provided for poor finished product selection, whether the dimensional tolerance of the product is OK or not is quickly prepared and judged according to the identification knife lines, the product appearance inspection (optical adhesive sheet products need full inspection, and the appearance is inspected manually) efficiency is improved, and the omission ratio is reduced. The efficiency of product quality control has been improved greatly, practices thrift labour cost.

Further, be equipped with the closed cutter 7 that is used for die-cut optical cement appearance in the middle of the carrier for die-cut product appearance, the cutting edge of closed cutter 7 is straight sword in the one side towards the material, is the oblique sword in the one side towards the waste material, because the one side towards the material is straight sword, consequently can not extrude the material, guarantees that the product surface is level and smooth. The inside cotton 1 of packing bubble that is equipped with of closed cutter can carry out cushioning effect to die-cut optical cement, avoids causing extrusion deformation to optical cement.
