Description

Technical Field

[0001] This utility model relates to the field of micro switch technology, specifically a micro switch detection device. Background Technology

[0002] Microswitches are electronic components that trigger circuit switching through minute mechanical displacement, and are widely used in home appliances, automobiles, and industrial equipment. Their testing typically involves verifying parameters such as mechanical triggering, electrical performance, and durability. Traditional testing methods suffer from the following problems: manual testing is inefficient, relying on operators manually pressing the switch and testing continuity with a multimeter, resulting in highly subjective results and an inability to quantify travel data; mechanical testing devices lack precision, single-point contact test heads are prone to false triggering due to assembly deviations; they lack displacement measurement capabilities, making it impossible to determine whether the switch has reached its nominal travel; and the fixing methods are inflexible, using screws or clips for fixation, requiring readjustment when replacing different switch models, which is time-consuming; they are also prone to loosening under vibration, affecting test consistency. Therefore, a microswitch testing device is needed to improve upon these issues. Utility Model Content

[0003] The purpose of this invention is to provide a micro switch detection device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a micro switch detection device, comprising a device body, a micro switch fixedly connected to one side of the device body, a controller provided on the front, a detachable magnetic suction component provided at the bottom of the device body, an adjustable detection arm extending from the device body, and a contact detection head and a laser ranging sensor provided at the end of the detection arm.

[0005] As a preferred embodiment of this utility model, the magnetic suction assembly includes a ring magnet and a metal detection arm fitted therewith, wherein the detection arm achieves adaptive adjustment of the detection head angle through a universal joint.

[0006] As a preferred embodiment of this utility model, the detection head is a three-claw floating structure, including three elastic conductive contacts that are evenly distributed. When any contact is pressed, a conduction signal can be triggered and logically verified with the data from the laser rangefinder sensor.

[0007] As a preferred embodiment of this utility model, the controller has a built-in comparator circuit, and the controller receives the displacement signal from the laser rangefinder and the contact signal from the detection head.

[0008] As a preferred embodiment of this utility model, the main body of the device has symmetrical positioning holes on both sides of the front, and a magnetically conductive metal sleeve is embedded in the positioning hole. The laser ranging sensor is arranged at an angle to the central axis of the detection head to avoid the detection head blocking the laser path.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model uses a laser rangefinder sensor to monitor the pressing displacement in real time, combined with the contact signal of the three-claw detection head. It is only determined to be a valid trigger when both conditions are met simultaneously, thus reducing the false detection rate. The three-claw floating structure ensures that even if the detection head is tilted to the switch surface, it can still maintain stable contact, avoiding misjudgment caused by uneven force at a single point.

[0011] 2. This invention uses a laser rangefinder sensor to monitor the pressing displacement in real time, combined with the contact signal from the three-claw detection head. A valid trigger is only determined when both conditions are met simultaneously, reducing the false detection rate. The floating three-claw structure ensures stable contact even when the detection head is tilted relative to the switch surface, avoiding misjudgments caused by uneven force at a single point. Magnetic quick installation allows for rapid adsorption and positioning, significantly improving the detection cycle time. The universal joint structure of the detection arm can automatically fine-tune the angle, reducing manual alignment time. Standardized signal output directly outputs on / off signals and displacement data without additional signal processing.

[0012] 3. This utility model can detect the switch travel through a laser rangefinder sensor, covering mainstream micro switch models. It has strong anti-interference ability, and the magnetic fixing method avoids screw loosening. It is suitable for vibration environments. The optical and mechanical dual signals can filter out instantaneous jitter interference. The detection head can be quickly replaced and is compatible with micro switches of different shapes.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a micro switch detection device, including a device body 1, a micro switch 2 fixedly connected to one side of the device body 1, a controller 9 provided on the front, a detachable magnetic suction component provided at the bottom of the device body 1, an adjustable detection arm 5 extending from the device body 1, and a contact detection head 6 and a laser rangefinder 3 provided at the end of the detection arm 5.

[0022] As an example of this utility model, the magnetic suction assembly includes a ring magnet 4 and a metal detection arm 5 fitted therewith, wherein the detection arm 5 achieves adaptive adjustment of the angle of the detection head 6 through a universal joint.

[0023] As an example of this utility model, the detection head 6 is a three-claw floating structure, including three elastic conductive contacts that are evenly distributed. When any contact is pressed, a conduction signal can be triggered and logically verified with the data of the laser rangefinder 3.

[0024] As an example of this utility model, the controller 9 has a built-in comparator circuit, and the controller (9) receives the displacement signal of the laser rangefinder 3 and the contact signal of the detection head 6.

[0025] As an example of this utility model, the main body 1 of the device has symmetrical positioning holes 8 on both sides of the front side, and a magnetically conductive metal sleeve is embedded in the positioning hole 8. The laser ranging sensor 3 is arranged at an angle to the central axis of the detection head 6 to avoid the detection head 6 from blocking the laser path.

[0026] Working principle: In use, align the main body 1 of the device with the external clamp through the positioning hole 8, ensuring that the detection head 6 is directly facing the micro switch contact to be tested. If manual installation is required, it can be directly attracted to the iron-containing surface of the device to be tested through the magnetic ring 4. The support plate 5 automatically adjusts the angle through the universal joint, so that the three-jaw contact of the detection head 6 is parallel and in contact with the surface of the micro switch. When the tilt error is small, at least two of the three-jaw contact points can maintain contact to avoid uneven force on a single point. When the micro switch 2 is pressed, the elastic contact of the detection head 6 is pressed and conducts, generating an electrical signal. The laser range sensor 3 measures the switch pressing displacement in real time, and the comparator circuit of the controller 9 judges the signal. The valid signal is output to the outside through the controller 9, and the trigger time, displacement and other parameters are recorded at the same time. The device can be disassembled by directly sliding it horizontally to overcome the magnetic attraction. The detection head 6 can be replaced separately.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
