A Gravity Adaptive Lift for LED TV Production Line

Abstract

The invention discloses a gravity self-adaptive lifter for LED TV production line, which comprises two longitudinal supports arranged oppositely, a fixed friction plate and a loading platform between the two longitudinal supports, and the two longitudinal supports are opposite to each other. One side of the loading platform is provided with rolling grooves; the upper plane of one end of the loading platform is connected to the lifting motor through a cable, the lifting motor is located above the loading platform, and the lower plane of the other end of the loading platform is rotated and installed on the cross bar. The end is rolled and installed in the rolling groove; the middle part of the crossbar is rotated and installed with a herringbone friction strut, and the sliding plate fixedly connected at one end is limited in the rectangular groove on the lower plane of the loading platform, and the sliding friction strut fixedly connected at the other end The plate and the fixed friction plate are in contact with each other. The invention realizes the automatic matching and adaptation of the frictional resistance and the gravity, achieves the purpose of uniformly lowering the goods on the loading platform, and has the advantages of energy saving, simple and reliable 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
