A locking method and device for a locking mechanism

Abstract

The present application discloses a method for locking a locking mechanism. The method includes: in response to a locking instruction, judging whether the locking mechanism is in a locked-in position state; if the locking mechanism is in a non-locked closed-in position state , then configure the parameters of the motor controller of the locking mechanism; determine the corresponding locking conditions of the locking mechanism according to the type of the no-load state of the locking mechanism; if the locking mechanism satisfies the lock If the locking condition corresponding to the locking mechanism is satisfied, it is determined that the locking mechanism is locked. Since the locking conditions corresponding to the locking mechanism are respectively set for the two cases in which the no-load state type of the locking mechanism is no-load and full-load, even if it is impossible to detect in time whether the locking mechanism is no-load or full-load In any case, the locking process can be implemented, so that the locking method of the locking mechanism provided in this embodiment can be compatible with the process of implementing the locking mechanism to complete the locking process when the locking mechanism is empty or fully loaded.

Description

technical field [0001] The present application relates to the technical field of locking mechanisms, and in particular, to a locking method and device for a locking mechanism. Background technique [0002] In the technical field of locking mechanisms, the locking device should not only achieve reliable locking of the product during transportation, but also achieve reliable locking during the loading and unloading process to prevent large equipment from rolling, which is suitable for the locking device. Security, reliability, and reliability put forward higher requirements. [0003] With the development of locking mechanism technology, the electric cylinder-driven locking method is generally used at this stage. In this electric cylinder-driven locking method, the locking force is set by the peak current of the motor controller, and is determined by the proximity switch signal. The relative displacement of the electric cylinder is calculated by the resolver signal of the moto...

AI Technical Summary

Problems solved by technology

There are three main problems in this control method: 1. The locking mechanism under load requires the motor to rely on the current corresponding to the locking force to reliably lock the product; No need to lock

If only relying on the in-position proximity switch of the mechanism as the criterion for locking in place, the locking force under load cannot be accurately controlled. If the in-position proximity switch sensor is triggered too early, there will be a gap between the locking mechanism and the product, making it impossible to lock reliably. , the product will roll during transportation or reloading

If the proximity switch sensor is adjusted to trigger later, the close position sensor may not be triggered under load

This makes the current control method difficult to be compatible with empty and full load; Second, once the peak current of the motor controller is set, the maximum driving force of the electric cylinder cannot be adjusted during the operation of the motor, and the load force of the actual mechanism is affected by high and low temperature , at low temperature, due to changes in the lubrication system of the motor and the locking mechanism, the load becomes larger, and a larger current is required to overcome the resistance during operation. This requires the motor controller to set a larger peak value during the operation of the locking mechanism. Current, when the locking mechanism is about to move into place, set the peak current corresponding to the locking force required by the product

The peak current of the current control method cannot be modified once it is set, so it cannot adapt to high and low temperatures; 3. The reliability is not high: once the in-position proximity switch sensor fails or is not triggered reliably, the locking process cannot be automatically ended, affecting the transportation and reprinting of the product process reliability
