Clamp assembly, net tensioner and method of use thereof

Abstract

The present disclosure relates to the technical field of liquid crystal display. Embodiments of the present disclosure provide a clamp assembly, a net stretching machine and a method for using the same. In one embodiment, a clamp assembly includes at least a first clamp unit. The first gripper unit includes: a first coarse adjustment gripper member for applying a stretching force to the target sheet in a first direction, and a first rough adjustment gripper member for stretching the target sheet in at least one of the first direction and the second direction. A first fine-tuning clamp member that applies tensile force to the material. Here, the first direction and the second direction intersect each other and define a plane on which the target sheet exists. The first fine adjustment jig member is disposed inside the first coarse adjustment jig member, and the first fine adjustment jig member is movable in at least one of a first direction and a second direction relative to the first coarse adjustment jig member.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a clamp assembly, a net stretching machine and a method for using the same. Background technique [0002] In the display technology, a fine metal mask (Fine Metal Mask, FMM) is used in an evaporation process to evaporate an organic material to a specified position on a substrate. The flatness of the fine metal mask directly affects the effect of evaporation. Stretching of a sheet as a mask raw material is performed using a stretching device. When using the clamps in the existing stretching equipment to stretch the sheet, due to the simple design of the clamps and limited adjustment capabilities (for example, a single force direction), the wrinkles formed on the FMM during the stretching process cannot be effectively alleviated. As a result, the effect of vapor deposition is affected, resulting in color mixing of the display device, which is not conducive to the yield ...

AI Technical Summary

Problems solved by technology

When using the clamps in the existing stretching equipment to stretch the sheet, due to the simple design of the clamps and limited adjustment capabilities (for example, a single force direction), the wrinkles formed on the FMM during the stretching process cannot be effectively alleviated. As a result, the effect of evaporation is affected, which in turn leads to color mixing of the display device, which is not conducive to the yield of the display device
