Gravity self-adaption elevator for LED television production line

Abstract

The invention discloses a gravity self-adaption elevator for an LED television production line. The gravity self-adaption elevator for the LED television production line comprises two oppositely-arranged longitudinal supports, and a fixed friction board and a carrying platform which are located between the two longitudinal supports. Rolling grooves are formed in the opposite sides of the two longitudinal supports. The upper plane at one end of the carrying platform is connected with an elevating motor through a cable. The elevating motor is located above the carrying platform. The lower plane at the other end of the carrying platform is rotationally installed on a transverse rod. The two ends of the transverse rod are installed in the rolling grooves in a rolling manner. A herringbone friction supporting rod is rotationally installed in the middle of the transverse rod, a flat sliding board fixedly connected to one end of the herringbone friction supporting rod is limited in a rectangular groove in the lower plane of the carrying platform, and a sliding friction board fixedly connected to the other end of the herringbone friction supporting rod makes contact with a fixing friction board. By the adoption of the gravity self-adaption elevator, friction force, resistance and gravity are automatically matched and are adaptive, goods on the carrying platform descend at constant speed, and therefore the gravity self-adaption elevator has the beneficial effects of being capable of saving energy consumption and simple and reliable in structure.

Description

technical field [0001] The invention relates to a lift for an LED TV production line, in particular to a gravity self-adaptive lift for the LED TV production line. Background technique [0002] As one of the best-selling household appliances, LED TVs are increasing year by year, especially the growth trend of large-size LED TVs. The major LED TV manufacturers also regard large-size LED TVs as the main direction of future product development. . Due to the gradual increase in the size and weight of large-size LED TVs, in order to improve production efficiency and reduce the labor intensity of front-line workers, major LED TV manufacturers have gradually adopted automatic LED TV production lines, especially large-size LED TV transportation production lines have been widely used. use. At the same time, the LED TV production line includes production, assembly and monitoring processes, resulting in generally long production lines. Therefore, at present, major manufacturers adopt...

AI Technical Summary

Problems solved by technology

[0005] (1) Fully use the lifting motor to lower the transported LED TV, that is, the elevator motor needs to provide power during the lifting and lowering actions. For the continuous operation of the production line elevator, there is a disadvantage of high energy consumption, which may even cause the motor Overheating failures lead to elevator failures and affect production line efficiency

[0006] (2) The technical scheme of passenger elevator is adopted, and the weight is added to increase the stability of transportation. However, the weight of the added weight is constant and cannot be changed with the weight of the LED TV being transported. For the production line, the station elevator In the lifting stage, the motor is required to provide the power to lift the counterweight, which increases additional energy consumption
