Method used

An aluminum trapezoidal fixture for polarizing plate production is designed, including a bottom plate, a longitudinal support plate, a transverse support plate and a top plate. Through the combination and connection of these components, the downward force of the cylinder is transmitted to the corners of the product to the greatest extent, ensuring the stability of the product during the grinding process.

Benefits of technology

The corners of the product are compacted by the self-weight of the trapezoidal fixture, which avoids the product's defects during the grinding process, and solves the problems of offset and corner compression, and the overall yield is increased by about 5%.

Description

Technical Field

[0001] The utility model relates to an aluminum trapezoidal fixture for producing polarizing plates, belonging to the technical field of auxiliary equipment for producing polarizing plates. Background Art

[0002] In the production process of polarizing plates, the edging process is a very important process. It is necessary to ensure that the product (i.e. polarizing plate) cannot be displaced during the entire grinding process, and the corners of the product need to be pressed as tightly as possible, otherwise it will affect the overall end face quality and dimensional accuracy of the product.

[0003] The conventional operation for compaction is to place a bakelite pressing plate above and below the product for protection. Since the stroke of the cylinder is limited and the height of each column of products is inconsistent, the traditional method is to fill multiple nylon pads between the cylinder pressure plate and the upper bakelite pressure plate to make up for the height difference. Since the size of the product and the bakelite pressure plate is much larger than the diameter of the cylinder pressure plate, and the size of the nylon pad is also much smaller than the size of the product and the bakelite pressure plate, the actual force-bearing area of ​​the product is small. After the cylinder pressure plate is compacted, the corners of the product cannot be effectively compacted by the cylinder pressure, which makes the product prone to defects during the grinding process. Utility Model Content

[0004] The utility model aims to provide an aluminum trapezoidal fixture for producing polarizing plates, so as to solve the technical problems existing in the current production process of polarizing plates.

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Embodiment 1

[0025] like Figure 1 and 2 As shown, this embodiment is an aluminum trapezoidal fixture for producing polarizing plates, comprising:

[0026] Bottom plate 1, used for contacting with the upper bakelite pressing plate, the size of bottom plate 1 is consistent with the size of the upper bakelite pressing plate;

[0027] Two longitudinal support plates 2 are provided, and the two longitudinal support plates 2 are respectively provided on both sides of the top of the bottom plate 1 and arranged along the length direction of the bottom plate 1;

[0028] There are five transverse support plates 3, which are arranged between two longitudinal support plates 2 and arranged along the width direction of the bottom plate 1; of course, the number of transverse support plates 3 can also be appropriately increased or decreased;

[0029] The top plate 4 is arranged on the top of the longitudinal support plate 2 and the transverse support plate 3 for contacting with the nylon pad. The length of the top plate 4 is smaller than the length of the bottom plate 1. Inclined surfaces are formed at both ends of the longitudinal support plate 2 not covered by the top plate 4.

[0030] In this embodiment, the bottom plate 1, the longitudinal support plate 2, the transverse support plate 3 and the top plate 4 are detachably connected by a plurality of screws, that is, the longitudinal support plate 2 and the bottom plate 1, the transverse support plate 3 and the bottom plate 1, the longitudinal support plate 2 and the transverse support plate 3, the longitudinal support plate 2 and the top plate 4, and the transverse support plate 3 and the top plate 4 are all detachably connected by a plurality of screws. In this embodiment, the transverse support plates 3 and the top plate 4 at the two ends are connected by screws, and the other transverse support plates 3 and the top plate 4 are not connected; the detachable connection by screws facilitates the overall modular assembly.

[0031] In this embodiment, the bottom plate 1 , the longitudinal support plate 2 and the transverse support plate 3 are all provided with deweighting holes 5 .

Taking the 42-inch product matching jig as an example, the overall weight of the jig is controlled at about 15kg; after adopting the utility model, the structure from top to bottom is transformed from "cylinder pressure plate → nylon pad → upper bakelite pressure plate → product → lower bakelite pressure plate" to "cylinder pressure plate → nylon pad → trapezoidal jig → upper bakelite pressure plate → product → lower bakelite pressure plate", and the corners of the product are compacted by the dead weight of the trapezoidal jig, and the downward pressure of the cylinder is transmitted to the corners of the product to the greatest extent through the trapezoidal jig, thereby avoiding defects in the product during the grinding process.
