Specifically, the present embodiment provides a detection mechanism applied to a mechanical device, for detecting a target component 3 moving along a first direction a on a first surface, so as to perform a preset action when the target component 3 reaches a specified position, where the mechanical device may be a device including a conveying mechanism, the first surface may be a surface of the conveying mechanism, at present, the mechanical device generally adopts a position detection element 1, if the position detection element 1 is damaged, an in-place signal may be sent in advance or delayed, or an in-place signal may not be sent, which may cause malfunction of the mechanical device, and serious damage to the device or injury to a person.

In the technical scheme adopted by the utility model, at least two position detection elements 1 are adopted, for convenience of description, the two position detection elements 1 are taken as an example, the two position detection elements 1 are arranged at intervals in a second direction b, the second direction b is perpendicular to the moving direction of the target part 3, namely perpendicular to a first direction a and parallel to a first surface, the two position detection elements are arranged on one side of the first surface in a third direction c, the third direction c is perpendicular to the first surface, when the first surface is a horizontal surface, the third direction c is longitudinal, the two position detection elements 1 are positioned in the moving range of the target part 3, and when the target part 3 moves to the position of the two position detection elements 1, the two position detection elements 1 are required to detect the target part 3 in place at the same time in a normal working state and send out in-place signals; the position detection mechanism further comprises a control module, the control module is in signal connection with each position detection element 1 and the mechanical equipment, a preset standard value is stored in the control module in advance, the control module can receive in-place signals sent by the two position detection elements 1, in-place signals sent by the two position detection elements 1 are calculated to obtain an offset value, the offset value is compared with the preset standard value finally, and the control module can send at least one of a first instruction signal and a second instruction signal according to a comparison result.

The process of the control module sending out the instruction signal is specifically as follows: if the deviation value is not greater than the preset standard value, the two position detection elements are in a normal working state, the target component 3 is in place, and the control module only sends out a second instruction signal for instructing the mechanical equipment to execute the preset action; otherwise, if the deviation value is greater than the preset standard value, it indicates that one of the position detecting elements 1 is abnormal due to loosening, damage and the like, and sends out a signal in place in advance, after that or not, the control module sends out a first instruction signal before sending out a second instruction signal, so as to instruct the mechanical equipment to stop executing the preset action, and after obtaining the signal, the worker can check, repair or replace the position detecting element 1 so as to ensure the normal work of the position detecting mechanism.

The preset standard value can be set manually according to different mechanical equipment, and if the preset standard value is set incorrectly, the normal operation of the mechanical equipment is affected, for example: if the preset standard value is set too large, the protection effect cannot be achieved due to low sensitivity, otherwise, if the preset standard value is set too small, the difficulty of installation is increased due to too high sensitivity; the position detecting element 1 may be an inductive proximity switch or a capacitive proximity switch, but is not limited thereto, and may be another type of sensor or the like capable of realizing position detection.
