Abstract
The invention relates to a mechanical arm fork. The mechanical arm fork comprises multiple rigid structural bodies, wherein every two adjacent rigid structural bodies are connected through an elastic structural body. The invention further provides a mechanical arm. The mechanical arm is used for conveying a glass substrate of a liquid crystal display panel and comprises a mechanical arm main body and multiple mechanical arm forks connected to the mechanical arm main body. By means of the mechanical arm, alternating stress borne by the forks in the working process can be relieved through elastic connecting components, and thus fatigue-damage resistance of the forks is enhanced; and in addition, by means of the elastic connecting components, the forks can have greater elasticity. Vibration generated in the carrying process of the glass substrate is relieved; the possibility that glass is broken due to vibration is reduced; meanwhile, the mechanical arm is simple in structure, low in material cost and simple in manufacturing process, and cost of the mechanical arm is greatly lowered; and the mechanical arm fork and the mechanical arm are suitable for large-scale industrialized production.
