Embodiment 1

[0031] figure 1 It is a logic block diagram of a detection system of a proximity switch according to Embodiment 1 of the present invention. The detection system includes a programmable controller 110, a trigger module 120 and a drive assembly 130, wherein: the programmable controller 110 triggers the drive assembly 130 to drive the trigger module 120 to move; the trigger module 120 triggers at least two Proximity switch 140: the programmable controller 110 determines whether the at least two proximity switches 140 are normal according to whether the proximity switch 140 at the corresponding position is triggered when the trigger module 120 moves.

[0032] Among them, the programmable controller 110 (ie, PLC, ProgrammableLogicController) is used to perform operations such as stored logic operations and sequence control, timing, counting, and arithmetic operations, and through digital or analog input interfaces and output interfaces, control The control unit for the correspondi...

Embodiment 2

[0036] figure 2 It is an assembly drawing of the tooling structure of the detection system of the proximity switch according to the second embodiment of the present invention. The detection system includes figure 1 All the functional units of the detection system of the proximity switch are shown, and on the basis of them, they are improved, and the improvements are as follows:

[0037] In order to realize the batch detection of contact switches, the tooling for the batch testing can be designed, and the structure of the designed tooling can be adjusted according to the actual situation. like figure 2 As shown, the trigger module 120 may include a first slider 121 and a rotating platform 122 , the first slider 121 is fixedly mounted on the rotating platform 122 and rotates with the rotating platform 122 .

[0038] like figure 2 As shown, the detection system of the proximity switch includes a sensing platform 150, a base 160, a drive assembly 130, a trigger module 120, ...

Embodiment 3

[0050] Image 6 It is a flow chart of the detection method of the proximity switch according to the third embodiment of the present invention. by including as Figure 7 The detection device shown carries out the detection method.

[0051] refer to Image 6 , in step S610, acquire the mobile location information of the trigger module.

[0052] Specifically, based on figure 2 The detection system of the proximity switch, when it is necessary to detect multiple proximity switches, the multiple proximity switches can be installed on the sensing platform. In order to improve the detection efficiency, multiple proximity switches can be installed in the radial direction of the rotating platform, which can be The programming controller can send the speed signal to the motor driver, and the motor driver can convert the speed signal into a pulse signal and send it to the stepping motor, and the stepping motor drives the rotating platform to rotate. The programmable controller can ...

Abstract

The invention provides a detection device, method and system of an approach switch. The detection method is used for detecting at least two approach switches, wherein the approach switches are triggered through a triggering module. The detection method comprises the following steps: acquiring movable position information of the triggering module; detecting whether the approach switches at pre-set positions are triggered or not according to the movable position information and pre-set position information; and determining whether the two approach switches are normal or not according to whether the approach switches at the pre-set positions are triggered or not. With the adoption of the embodiment of the invention, the detection efficiency of the approach switches can be improved.

Description

technical field [0001] The invention relates to proximity switch technology, in particular to a detection method, device and system for a proximity switch. Background technique [0002] In industrial applications, proximity switches are widely used and exist in large quantities in products or manufacturing equipment. However, how to detect proximity switches has become an important problem that needs to be solved. [0003] A test bench usually used to detect proximity switches has a horizontal chute and a vertical chute, the horizontal chute is provided with a junction box, and the vertical chute is provided with a metal block. The proximity switch to be tested is set in the horizontal chute, and the switch state of the proximity switch is detected in real time by sliding the metal block along the vertical chute. In this way, it is tested whether the proximity switch to be tested is normal. If it is normal, the proximity switch to be tested can also be detected. The sensing...
