Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sensor equipment, in particular to an infrared self-locking sensor. Background Art
[0002] During the operation of the robotic arm, it will be locked after running to the specified position. However, when the robotic arm runs to the specified position and triggers the limit signal, the locking component needs a period of reaction time from receiving the signal to executing it. During this reaction time, the robotic arm is still running, causing the robotic arm to over-run beyond the specified position, which in turn leads to low operation accuracy and poor work efficiency of the robotic arm. Utility Model Content
[0003] The utility model aims to provide an infrared self-locking sensor which can effectively improve the limiting accuracy of a mechanical arm and thus improve the working efficiency of the mechanical arm.
[0004] The utility model is achieved in this way:
[0005] An infrared self-locking sensor comprises a limit sensor for sending a limit signal and a locker for locking a mechanical arm. An infrared sensor for detecting the position of the mechanical arm is arranged between the limit sensor and the locker. The locker, infrared sensor and limit sensor are arranged in sequence along the running direction of the mechanical arm.
[0006] Further, the lock is connected to a first shell for installation, the infrared sensor is connected to a second shell for installation, and the limit sensor is connected to a third shell for installation. The first shell, the second shell, and the third shell are arranged in parallel and connected in sequence. A first guide rail is fixedly connected to one side where the first shell is connected to the second shell, and the first guide rail is in a "T" shape. A first limit groove matching the first guide rail is provided on one side where the second shell is connected to the first shell, and the first guide rail is movably embedded in the first limit groove. A second guide rail is fixedly connected to one side where the second shell is connected to the third shell, and the second guide rail is in a "T" shape. A second limit groove matching the second guide rail is provided on one side where the third shell is connected to the second shell, and the second guide rail is movably embedded in the second limit groove.
[0007] Furthermore, the locker is an electromagnet.
[0008] Furthermore, the limit sensor is a limit switch.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] In actual application, when the infrared sensor detects the position of the robotic arm, it feeds back a signal to the external controller, and the external controller controls the lock to start. When the limit sensor senses that the robotic arm has reached the specified position, it feeds back a signal to the external controller, and the external controller controls the lock to lock the robotic arm. The infrared sensor detects the running position of the robotic arm and starts preheating the lock in advance, which offsets the delay time from the start to the execution of the lock, allowing the robotic arm to flexibly contact with the limit sensor, thereby improving the operating accuracy of the robotic arm and thereby improving the working efficiency of the robotic arm. The utility model effectively improves the limit accuracy of the robotic arm and thereby improves the working efficiency of the robotic arm. BRIEF DESCRIPTION OF THE DRAWINGS
