For further understanding of the contents, features and functions of the present invention, the following embodiments will be exemplified in conjunction with the accompanying drawings as follows:

referring to fig. 1, fig. 1 is a schematic front structure view of a polarizer cutting die in this embodiment. The polarizing plate cutting die in this embodiment includes a substrate 1, a plurality of rectangular cutting edge grooves 2, and a plurality of hole-shaped cutting edge grooves 3. The plurality of rectangular blade grooves 2 are formed in the front surface of the substrate 1, the plurality of hole-shaped blade grooves 3 are formed in the front surface of the substrate 1, and the plurality of hole-shaped blade grooves 3 are respectively arranged in the plurality of rectangular blade grooves 2 in a one-to-one correspondence manner.

Through set up hole shape sword groove 3 in rectangle sword groove 2 for the polaroid can directly cut out the polaroid that is applicable to comprehensive screen cell-phone cutting, then grind again can, reduced the process of punching, and then promote the production efficiency of polaroid.

Preferably, the hole-shaped edge groove 3 is close to one corner of the rectangular edge groove 2. The position of the hole-shaped blade groove 3 in the rectangular blade groove 2 is determined according to the position of a front camera designed for the full-screen mobile phone, so that the position of a circular hole for cutting the polaroid can correspond to the position of the front camera of the full-screen mobile phone.

Referring to fig. 2, fig. 2 is a schematic view of a back structure of the polarizer cutting die in this embodiment. Further, the polarizer cutting die in this embodiment further includes a plurality of magnets 4. The plurality of magnets 4 are provided on the back surface of the substrate 1.

It can be understood that, for once only cutting more polaroids, more rectangle sword groove 2 and hole shape sword groove 3 can be set up on the base plate 1, and can concentrate on the middle part of base plate 1, and the cutting die is when using, the side of base plate 1 is held through the manipulator centre gripping of die cutting machine, the polaroid that treats cutting downwards in more rectangle sword groove 2 and hole shape sword groove 3 orientation, concentrate on the middle part of base plate 1 again, under the effect of gravity, can lead to the middle part of base plate 1 to bear weight great, make slight undercut appear in base plate 1, influence the cutting quality of cutting die. Through a plurality of magnetism 4 settings of inhaling at the back of base plate 1, carry out supplementary absorption to base plate 1, avoided above-mentioned base plate 1's sunken problem, guarantee the quality that cuts of cutting die. When concrete application, magnetism is inhaled 4 and is adopted magnet, and it is adsorbed on the manipulator of die cutting machine through magnetic attraction, and this kind of adsorption state is also comparatively convenient when dismantling to the use of cutting die is convenient for.

In this embodiment, the plurality of magnets 4 may be arranged in a matrix, or may be arranged in a regular shape, such as a quadrangle, a pentagon, or a hexagon. Preferably, a plurality of magnets 4 are close to the middle portion of the substrate 1, wherein one magnet 4 can be disposed at the center of the substrate 1. Preferably, the magnetic piece 4 is plate-shaped and is embedded in the back surface of the substrate 1, and the surface of the magnetic piece 4 is flush with the back surface of the substrate 1.

Referring to fig. 1 and 2 again, a holding position 11 is disposed on a side of the substrate 1. The handheld position 11 is in a strip hole shape, is adaptive to the size of a palm of a human body, and is convenient for taking the cutting die. Preferably, the number of the handgrips 11 is plural, and the plurality of the handgrips 11 are respectively disposed on two opposite sides of the substrate 11. The number of the holding positions 11 in this embodiment is four, and the four holding positions 11 are respectively arranged on the side of the substrate 1 two by two.

Referring back to fig. 1, further, the front surface of the substrate 1 is provided with a nameplate region 12. The nameplate region 12 is located at a side of the substrate 1. The nameplate area 12 records the basic information of the cutting die, and the management of the cutting die is convenient. In a specific arrangement, the nameplate region 12 is located between the oppositely arranged hand-held positions 11. Preferably, the front surface of the base plate 11 is further provided with an indication arrow 13 for guiding the arrow during storage and for guiding the arrow during assembly to a die cutting machine manipulator, and the indication arrow 13 is opposite to the nameplate area 12 during specific arrangement.

With continued reference to fig. 1 and 3, fig. 3 is an enlarged view of portion a of fig. 1 in the present embodiment. Furthermore, a plurality of rectangular blade grooves 2 are arranged vertically and horizontally on the front surface of the substrate 1; the plurality of rectangular blade grooves 2 which are longitudinally arranged are arranged at intervals, and two adjacent rectangular blade grooves 2 in the plurality of rectangular blade grooves 2 which are transversely arranged are spliced. Preferably, the arc-shaped transition structure 5 is arranged at the splicing position where two adjacent rectangular blade grooves 2 are spliced.

It can be understood that, the comprehensive screen cell-phone has R angle structure, rectangle sword groove 2 also need set up R angle structure in order to adapt to the structure of the comprehensive screen cell-phone, splice department between two rectangle sword grooves 2 of so mutual concatenation will form an acute angle, and when the cutting die cuts the polaroid, the stress concentration of acute angle splice department, may lead to cutting the crackle, and splice department through two rectangle sword grooves 2 sets up arc transition structure 5, can reduce the cutting stress of splice department, avoid the appearance of crackle, at follow-up grinding process, grind the unnecessary part that falls arc transition structure 5, in order to obtain the certified products. The arc transition structure 5 in this embodiment may adopt an arc angle with a radius of 0.5 mm.

Referring again to fig. 3, further, the rectangular blade groove 2 is provided with an extension 21. The extension 21 is an arc extension, and is a micro arc structure which is protruded outwards from the inside of the rectangular blade groove 2, so that the stress is further reduced during cutting, and the cutting quality of the polaroid is further ensured. During subsequent grinding, the epitaxy 21 is ground away. The extension 21 in this example is 0.3 mm.

The polarizer cutting die in this embodiment further includes a ventilation groove (not shown) to facilitate gas discharge during cutting. The base plate 1 in this example was made of a finnish wood board. The rectangular blade groove 2 and the hole-shaped blade groove 3 are made of a Nippon Zhongshan mirror surface cutter.

The above is only an embodiment of the present invention, and is not intended to limit the present invention. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
