Locking method and device of locking mechanism

Abstract

The invention discloses a locking method of a locking mechanism. The method comprises the steps: in response to a locking instruction, judging whether the locking mechanism is in a locking in-place closing state; if the locking mechanism is in a non-locking in-place closing state, performing parameter configuration on a motor controller of the locking mechanism; determining a locking condition corresponding to the locking mechanism according to the empty and full load state type of the locking mechanism; and if the locking mechanism meets the locking condition corresponding to the locking mechanism, determining that the locking mechanism is locked. As the locking conditions corresponding to the locking mechanism are respectively set under the two conditions that the empty and full load state types of the locking mechanism are the empty load and the full load, the locking process can be realized even if the condition that the locking mechanism is the empty load or the full load cannot be detected in time; and according to the locking method of the locking mechanism provided by the embodiment of the invention, the locking mechanism can be compatibly implemented to complete the locking process under the conditions of no load and full load of the locking mechanism.

Description

technical field [0001] The present application relates to the technical field of locking mechanisms, in particular to a locking method and device for locking mechanisms. Background technique [0002] In the field of locking mechanism technology, the locking device should not only realize the reliable locking of the product during transportation, but also realize the reliable locking of the product during the loading and unloading process, so as to prevent the rolling of large equipment, which is the adaptability of the locking device. Higher requirements are put forward for performance, safety and reliability. [0003] With the development of locking mechanism technology, the locking method driven by electric cylinder is generally used at this stage. In this locking method driven by electric cylinder, the locking force is set by the peak current of the motor controller and by the proximity switch signal. Feedback whether the locking mechanism is moving in place, and the rel...

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
