Problems solved by technology

In the past, manual adjustments were often used, relying on human eyes to observe the reference blisters. After repeated observations of the reference blisters, the result was repeated adjustments to meet the requirements. The adjustment time is long, easily affected by people, and the adjustment accuracy is not high.

Abstract

The invention relates to the technical field of lifting devices and discloses a four-point synchronous lifting system which comprises four single lifting mechanisms for lifting a processing platform,a limiting switch group, a MINOR group, a controller, a motor driver group and a contracting brake group, wherein each of the single lifting mechanisms is used for driving the processing platform to go up and down; the limiting switch is used for monitoring the up-down movement limit position of a movable plate on each single lifting mechanism; the MINOR is used for monitoring the movable positioninformation of the movable plate; and the controller is used for receiving a sensing signal and controlling brake and operation of the motor from the motor driver group and the contracting brake group. The four-point synchronous lifting system realizes trebling limiting including electric limiting from the limiting switch, software limiting from the MINOR and mechanical limiting from the contracting brake, can timely brake when the movable plate is lifted to a designated spot and ensures that the motion control precision and the adjusting precision of the processing platform can reach 0.1mm and 0.01mm separately.

Description

technical field [0001] The invention belongs to the technical field of lifting devices, in particular to a four-point synchronous lifting system. Background technique [0002] The leveling device is the premise of optical system processing. Only when the optical raw materials are placed on a standard plane can precision processing be carried out. In the past, manual adjustments were often used, relying on human eyes to observe the reference blisters. After repeated observations of the reference blisters, the results required repeated adjustments to meet the requirements. The adjustment time is long, easily affected by people, and the adjustment accuracy is not high. [0003] Therefore, how to solve the above problems has become the focus of research by those skilled in the art. Contents of the invention [0004] The first object of the present invention is to provide a four-point synchronous lifting system, which has solved the shortcomings of the prior art. [0005] Emb...
