Introduction of sweeping robot:

In recent years, with the rapid development of computer technology and artificial intelligence science, intelligent robot technology has gradually become a hot spot in the field of modern robot research. Among them, service robots have opened up a new field of robot applications.

With the improvement of people’s living standards, more and more people pay attention to a healthy and comfortable home environment. Buying a house and decorating have become hot topics that people talk about after dinner, but the dirty and tiring cleaning work after decoration has become another major problem that plagues housewives. For many families, cleaning robots have become an essential small household appliance for cleaning homes.

Sweeping robots, also known as automatic cleaners, smart vacuum cleaners, robot vacuum cleaners, etc., are a type of smart household appliances that can automatically complete the floor cleaning work in the room with certain artificial intelligence. Generally, brushing and vacuuming are used to absorb the debris on the ground into its own garbage storage box, so as to complete the function of ground cleaning.

The working principle of the sweeping robot:

The automatic sweeping robot integrates mechanics, electronic technology, sensor technology, computer technology, control technology, robotics, artificial intelligence and many other disciplines.

The sweeping robot is controlled by a microcomputer, which can realize automatic navigation and clean and vacuum the ground. The collision head can avoid and bypass the obstacles in front, so that the corners it reaches can be cleaned. At the same time, the design of two large side sweeping wheels, The corners and the ground can be swept more thoroughly and cleanly. The relative rotation of the two cleaning wheels prevents the garbage from slipping away from the bottom of the body, and the cleaning is more complete. It can enter the garbage collection box more regularly and smoothly, and by installing photoelectric sensors on the front wheel and the power box of the sweeping wheel, the robot can have the function of automatically preventing the body from being stuck and the sweeping wheel being stuck. It automatically retreats or shuts down, and is equipped with an infrared reflection detector on the collision head, which can automatically determine whether the front is a cliff and automatically bypass it.

The mechanical structure of the sweeping robot:

The sweeping robot mainly includes the following parts:

  1. Walking drive wheel and drive motor. This part mainly ensures that the robot can move in the plane. Infrared switches are installed on the front and sides of the housing as a collision detection sensor. The 3 infrared switches on the bottom are used as step detection sensors to prevent falling. The drive wheel is equipped with a photoelectric encoder disk, which can detect and control the wheel speed, and realize positioning and path planning. At the same time, the ultrasonic sensor is also expanded for the needs of precise positioning;
  2. Cleaning mechanism. Use the motor to drive the two cleaning brushes, so that the left cleaning brush rotates clockwise, and the right side rotates counterclockwise, so that the dust can be concentrated at the suction port when cleaning the dust, so as to prepare for the work of the sweeping mechanism;
  3. Sweeping mechanism. Create a strong suction to suck the dust into the dust storage box;
  4. The wiping mechanism. After cleaning and sweeping, use the cleaning cloth installed under the casing to wipe off the fine dust remaining on the ground to ensure the quality of the cleaning work.

With the rapid development of computer technology, artificial intelligence technology, sensing technology and mobile robot technology in recent years, the research and development of sweeping robot control system has a solid foundation and good development prospects. The control and working environment of sweeping robots are often uncertain or changeable, so safety, reliability, anti-interference and cleanliness must be taken into account.

It is worth mentioning that the selection of the adhesive solution for the cleaning robot is of particular significance. Adhesives are used in a variety of applications on robot vacuums, from positioning microcircuits to bonding large motor coils. In addition to mechanical fastening, electrical adhesives also require special properties such as thermal conductivity, insulation, vibration damping, sealing and substrate protection.

Glue requirements for sweeping robots:

  1. Power waterproof;
  2. Bonding and fixing of circuit board components;
  3. Excellent heat dissipation for heating components;
  4. The circuit board is moisture-proof, mildew-proof, acid-alkali-proof, dust-proof, shock-proof and salt-fog proof;
  5. It has the characteristics of dustproof, waterproof, shock resistance, compression resistance, high temperature resistance and low temperature resistance.
