In recent years, with the development of computer technology, artificial intelligence technology, sensing technology and mobile robot technology, many intelligent systems have begun to be applied to small household appliances, and representative ones are intelligent sweeping robots. Since the US iRobot launched the world's first sweeping robot in 2002, sweeping robots have become popular around the world. Consumers around the world, including China, can enjoy the pleasure of smart sweeping robots when cleaning home hygiene. Since home cleaning is done by intelligent sweeping robots alone, no one can look after these smart sweeping robots when cleaning. When the fault occurs, the robot should be able to protect in time and resume normal work after troubleshooting. Therefore, for the manufacturers of intelligent sweeping robots, the intelligentization of products is important, but the products with reliable quality are more important to consumers. This article focuses on the protection solutions for smart sweeping robots.
First, TE connecTIvity company PolySwitch series product introduction
TE connecTIvity is the world's largest professional supplier of passive components and the world's largest supplier of circuit protection devices. It is the inventor of positive temperature coefficient resistors for polymer materials. Its overcurrent and overvoltage protection devices are widely used in consumer electronics. , IT, communications, industrial, automotive and other fields.
In terms of overcurrent protection, Tyco Electronics offers PolySwith self-recovery components. In terms of overvoltage protection, Tyco Electronics provides GDT gas discharge tubes and PESD/SESD electrostatic protection components. In addition, Tyco Electronics offers integrated protection components 2Pro and PolyZEN. , MHP, RTP and many other products.
TE connecTIvity is available in a wide range of PolySwitch models, such as the Radial-leaded, Surface-mount and LVR series of resettable circuit protection components, which are designed to prevent overloading and overheating of motors and transformers used in commercial and household appliances. Devices that are damaged by stalls, neutral faults, and other potential factors, as well as dedicated strap packages on the battery, can reset circuit protection components.
TE connecTIvity's Radial-leaded, Surface-mount and LVR series include a wide range of 16VDC, 24VDC, 30VDC, 72VDC or even 110VAC and 240VAC line voltage ratings. These products offer low impedance, fast operating time, small size and The resettable feature helps circuit designers introduce safe and reliable products and reduces repair costs during the warranty period.
Unlike single-use fuses, PolySwitch components do not need to be replaced after a fault. After the overcurrent condition is removed and the power is turned off, the circuit will return to normal operating conditions. Compared to bimetal circuit breakers, PolySwitch offers greater flexibility, longer life and lower electromagnetic interference (EMI).
Second, the introduction of intelligent sweeping robot
The intelligent sweeping robot utilizes the principle of ultrasonic ranging to transmit the ultrasonic pulse to the forward direction and accept the corresponding return acoustic pulse to judge the obstacle. The MCU or DSP is the core controller to realize the ultrasonic emission and acceptance control. And judged on the basis of processing the return pulse signal, thereby selecting an optimized path, driving two stepping motors through the driver, driving the driving wheel to realize the walking function. At the same time, the dust-collecting part carried by itself carries out dust cleaning on the passing ground.
Generally, the intelligent sweeping robot consists of a complex system consisting of a moving mechanism, a sensing system, a control system, a cleaning system, and a power system. The moving mechanism is the main body of the intelligent sweeping robot, which determines the moving space of the robot, and the household sweeping robot generally adopts Wheeled mechanism. Perceptual systems generally use ultrasonic sensors, contact and proximity sensors, infrared sensors, etc. to sense external intricate environmental information. The control system uses the above various sensors to obtain various signals required for robot control. These signals are sent to the controller, which is stored, calculated, processed by the controller, and then issued corresponding commands to make the intelligent sweeping robot through the actuator. The mechanical body completes the prescribed action. The cleaning system generally has a main ground brush, a side brush and a vacuum cleaner. The main ground brush and the side brush are used to strongly clean the adsorbed material on the floor, and the vacuum cleaner absorbs small objects on the floor. The power system refers to the power supply mode of the intelligent sweeping robot. Since the sweeping robot works in an autonomous manner, the power source used is a battery that is carried by a random body, so that not only can the unmanned control be realized, but also the work is flexible, and the charging can be performed once. Work for several hours in a row.

16MM Metal Switches
Yeswitch 16MM Metal Switches could be divided into aluminum casing and stainless steel casing and also could be divided into Momentary Switch and self-locking Metal Push Button Switch .
This 16MM series Waterproof Push Button Switch offer a long life expectancy, could used in Industrial control instruments, Medical equipment, Security monitoring equipment, Vehicle peripherals, Audio-visual equipment and Energy storage equipment,etc.
In addition, All casings are made through high-precision lathes, and the polishing and plating are rigorously screened. The metal fittings inside the metal switches are made of brass gold plated material, so the switch can have good conduction function and stable quality after long-term use.
The 16 series illuminated metal switches offer a long life expectancy, water resistance to IP67 ratings, and ring or power symbol illumination.This switch has a 16mm panel cutout size. Additional options include a high, high flat or rounded bezel option, and your choice of a solder lug or wire lead termination.
As for the indicator light , we offer customized service, customers could choose the effect , shape and the color. What is worth mentioning is that our indicator light could offer double color, which could offer our customers more choose in the item of light. Meanwhile, on the item of terminal shape, we could also offer customized service, we have solder terminal and free wire length could choose, 500mm is the normal standard.
This serious metal push button switches are of high quality and reliable products. The switch has passed IP67 dust proof and waterproof certification, which indicates it can be operated in harsh environments. Moreover, all materials could meet the European and American environmental protection requirements , for example, UL and ROHS certificate.
