Two polarizers are closely attached to the front and back of the liquid crystal display to form a liquid crystal film with a total thickness of about 1mm, which can realize the characteristics of high brightness and high contrast of the liquid crystal display. Therefore, the polarizer has become a necessary element for the imaging of the liquid crystal display.

With the wide application and updating of liquid crystal display technology, the size of liquid crystal displays is getting smaller and smaller. Usually a stack of polarizers are processed at the same time, and the width of a single single-side grinding is generally not more than 1mm, so the dimensional accuracy in grinding and cutting The requirements are quite high, generally within 0.05mm. Although the current edging machines on the market can roughly meet the requirements for use, their structural design is not clever, the structure is relatively complex, the cost is high, the operation is cumbersome, and grinding and cutting are common Problems such as large accuracy error and uneven chamfering.

Technical realization elements:

In view of the above-mentioned shortcomings, the purpose of the present invention is to provide a polarizer edging machine with clever and reasonable structure design, easy realization, good grinding and cutting effect, and simple operation. To achieve the above purpose, the technical solution provided by the present utility model is:

A polarizer edging machine, which includes a frame, an edging device, a linear sliding mechanism, an index plate and a material pressing mechanism. The linear sliding mechanism is arranged on the horizontal work surface of the frame, and the index plate is arranged on On the linear sliding mechanism, the pressing mechanism is arranged on the linear sliding mechanism corresponding to the upper position of the indexing plate, and the two edging devices corresponding to the two sides of the linear sliding mechanism are symmetrically arranged on the vertical frame of the frame. The vertical frame is provided with a driving device which can drive the two edge grinding devices to move closer or away from the linear sliding mechanism.

As an improvement of the present invention, the frame includes a bottom frame, a marble horizontal plate and a marble vertical plate. The marble horizontal plate is arranged horizontally on the bottom frame to form the horizontal work surface, and the marble vertical plate is vertical. The vertical frame is formed on the horizontal marble plate.

As an improvement of the utility model, the linear sliding mechanism includes a support frame, a sliding seat, a servo motor, a ball screw pair, a linear guide, and a sliding block adapted to the linear guide, and the linear guide is set in a horizontal position. On the work surface, the sliding seat is movably arranged on the linear guide rail through a sliding block, the support frame includes a horizontal part and a vertical part vertically connected to one end of the horizontal part, and the lower end of the vertical part is fixed on the sliding seat, The servo motor is arranged on a horizontal work surface, and can drive the sliding seat to reciprocate on a linear guide through the ball screw pair.

As an improvement of the present invention, the pressing mechanism includes a pressing cylinder and a pressing block, the cylinder of the pressing cylinder is fixed on the vertical portion, and the piston rod of the pressing cylinder faces the dividing Dial, the pressure block is arranged on the piston rod.

As an improvement of the utility model, the driving device includes two driving components symmetrically arranged on a vertical frame, the driving components include a servo motor, a ball screw pair, a sliding plate, a horizontal guide rail and a sliding block adapted to the horizontal guide rail. , The horizontal guide rail is arranged on the side wall of the vertical frame, the sliding plate is movably arranged on the horizontal guide rail through the sliding block, the servo motor is arranged on the vertical frame, and can drive the sliding plate in the horizontal direction through a ball screw pair. Reciprocating movement on the guide rail.
