[0033] Example

[0034] like Figure 1As shown, an embodiment of the utility model provides a pressure plate jig, including a pressure plate body 100, wherein the pressure plate body 100 is provided with a first positioning hole 110 and a second positioning hole 120 penetrating through both sides of the pressure plate body 100; wherein the first positioning hole 110 is used to cooperate with a rectangular edge grinder to achieve fixation of the pressure plate body 100 and the rectangular edge grinder; the second positioning hole 120 is used to cooperate with a special-shaped edge grinder to achieve fixation of the pressure plate body 100 and the special-shaped edge grinder.

[0035] In the present embodiment, the pressure plate jig includes a pressure plate body 100, and the pressure plate body 100 is penetrated by a first positioning hole 110 and a second positioning hole 120, wherein the first positioning hole 110 can cooperate with a rectangular edge grinder to fix the pressure plate body 100 and the rectangular edge grinder, and the second positioning hole 120 can cooperate with a special-shaped edge grinder to fix the pressure plate body 100 and the special-shaped edge grinder. By setting the first positioning hole 110 and the second positioning hole 120 on the pressure plate body 100, when the pressure plate body 100 is used to fix the polarizer on different types of edge grinders, different positioning holes can be used to directly realize mutual regulation with the rectangular edge grinder or the special-shaped edge grinder, so that the pressure plate jig can be equipped with both the rectangular edge grinder and the special-shaped edge grinder at the same time, thereby improving the applicability of the positioning jig.

[0036] In some embodiments, there are four first positioning holes 110 , and the four first positioning holes 110 are respectively located at four right-angle positions of the first rectangle.

[0037] Among them, by setting the number of 4 first positioning holes 110, it can cooperate with the hole positions on the existing rectangular edge grinding machine positioning package to ensure the stability of the pressure plate fixture when used on the rectangular edge grinding machine, thereby ensuring the grinding quality of the polarizer.

[0038] like Figure 2 As shown, in some embodiments, the first positioning hole 110 includes a first aperture segment 111 and a second aperture segment 112, one end of the first aperture segment 111 is located on one side of the pressure plate body 100, the other end of the first aperture segment 111 is connected to one end of the second aperture segment 112, and the other end of the second aperture segment 112 is located on the other side of the pressure plate body 100, wherein the diameter of the first aperture segment 111 is smaller than the diameter of the second aperture segment 112.

[0039] Specifically, the diameter of the first aperture section 111 is smaller than the diameter of the second aperture section 112. The first aperture section 111 can allow the rod-shaped body of the screw structure to pass through, and the second aperture section 112 can cooperate with the nut of the screw structure to accommodate the nut, thereby ensuring the stability of the cooperation between the pressure plate fixture and the rectangular edge grinding machine.

[0043] like Figure 3 As shown, in some embodiments, the second positioning hole 120 includes a second conical section 121 and a second cylindrical section 122, wherein the large round end of the second conical section 121 is located on one side of the pressure plate body 100, the small round end of the second conical section 121 is connected to one end of the second cylindrical section 122, and the other end of the second cylindrical section 122 is located on the other side of the pressure plate body 100.

[0044] It should be noted that, as technical personnel in this field should know, for existing special-shaped edge grinding machine mechanisms, a positioning column structure is usually set on the supporting platform of the special-shaped edge grinding machine, and the mutual cooperation with the pressure plate jig is achieved through the positioning column structure. Specifically, in order to facilitate the mutual cooperation between the pressure plate jig and the special-shaped edge grinding machine, the structural design of the second conical section 121 is used to facilitate guidance.

[0045] In some embodiments, an intersection point of the first rectangle diagonals overlaps an intersection point of the second rectangle diagonals.

[0046] The stability of the overall structure is ensured by the structural design of the relative position, and the intersection points of the diagonals are overlapped, which can effectively ensure that the pressing plate body 100 can be compatible with the rectangular edge grinding machine and the special-shaped edge grinding machine.

[0047] In some embodiments, the pressing plate body 100 is an acrylic plate. By adopting the acrylic plate, the first positioning hole 110 and the second positioning hole 120 are conveniently matched with the rectangular edge grinding machine and the special-shaped edge grinding machine respectively.

[0048] The embodiment of the utility model further provides a polarizer edge grinding system, comprising at least two of the above-mentioned pressing plate jigs, and also comprising a rectangular edge grinding machine and a special-shaped edge grinding machine.

Based on the adaptability of the pressing plate jig, the pressing plate jig can be used interchangeably between two different edge grinding machines. When one of the machines is abnormal, the other machine can be used as a standby to make up for the shortage of production capacity downtime.

[0050] In some embodiments, the special-shaped edge grinding machine includes a first supporting platform, and the supporting platform is provided with a second positioning column that cooperates with the second positioning hole 120, one end of the second positioning column is a connecting end, and the connecting end is fixedly connected to the supporting platform, and the other end of the second positioning column is provided with a threaded structure, wherein the length of the second positioning column is greater than the thickness of the pressure plate body 100.

[0051] Among them, through the structural design of the second positioning column, it is convenient to realize the mutual regulation of the pressing plate body 100 and the special-shaped edge grinding machine, thereby ensuring the production effect of the polarizer.

[0052] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
