[0041] As can be seen from the above, by utilizing the rotation connection between the roller 2 and the base 1, the power of the motor is transmitted to the wheel through gear transmission or belt transmission to realize the automatic movement of the robot arm. It is worth noting that in order to ensure the normal rotation and movement of the roller 2, the roller 2 is a universal wheel that can be adjusted and moved according to the specific situation, so that the roller 2 drives the base 1 to move, and the base 1 moves into the cold storage. At the same time, the base 1 fixes and supports the entire spraying equipment. By utilizing the cooperation between the base 1 and the material box 3, the material is stored inside the material box 3. At the same time, a pressure sensor and a control are arranged in the material box 3. The controller is a logic programmable controller PLC. It is worth noting that the PLC controller is a digital operation electronic system, which uses a programmable memory to operate the pressure sensor and the position sensor, realize operation, control, calculation, etc., to ensure the automatic spraying effect in the material box 3, and use the pressure sensor to make the material enter the inside of the hose 7, to ensure that the base 1 moves and drives the connecting rod 6 and the motor 9 to move synchronously, and by pulling the connecting rod 6, the connecting rod 6 is rotated on the side wall of the movable seat 4, so that the connecting rod 6 drives the motor 9 to move upward, so that The motor 9 moves to a suitable position. It is worth noting that the movable seat 4 includes a rotating joint and a flexion-extension joint. The movable seat 4 between the connecting rod 6 and the base 1 is a flexion-extension joint. The joint structure adopts magnetic levitation joint technology to reduce mechanical friction and wear. The rotational connection between the motor 9 and the driver 10 is used to make the motor 9 drive the driver 10 and the sensor 13 to rotate synchronously. The speed and direction of the motor 9 are controlled by the driver 10. It is worth noting that in order to ensure the normal operation of the clamping seat 14, a telescopic rod is arranged between the clamping seat 14 and the sensor 13. Through the position sensor inside the sensor 13, the sensor 13 controls the movement effect of the clamping seat 14. At the same time, the sensor 13 is fixed to the output end of the motor 9, so that the motor 9 drives the sensor 13 to rotate. It is usually connected to the motor to ensure the rotational connection between the telescopic rod and the clamping seat 14. It is worth noting that the pressure sensor: real-time monitoring of the pressure in the paint supply system, a total of two, the first one is installed at the compressor outlet to monitor the paint pressure output by the pump; the second one is installed on the paint pipeline near the spray gun to directly measure the pressure at the inlet of the spray gun. Position sensor: determine the relationship between the robot and the environment.An ultrasonic sensor or an infrared sensor is installed, one on the front and on both sides of the fuselage, to detect obstacles and determine the position. The clamping rod 9 is moved by the telescopic rod on one side of the sensor 13, and the motor 9 drives the sensor 13 to rotate, so that the clamping seat 14 rotates with the rotation of the sensor 13. The outside of the hose 7 is connected to the outside of the sensor 13, and the nozzle 15 at one end of the hose 7 moves with the movement of the sensor 13. In order to achieve the spraying effect on the object, the pressure sensor table inside the material box 3 is provided with an air compressor and a filter to achieve the squeezing and filtering effect on the material. The hose 7 is driven to move by the clamping seat 14, so that the polyurethane material in the hose 7 can be sprayed. The material is sprayed on the side wall of the cold storage. It is worth noting that joints are arranged between the motor 9, the sensor 13 and the clamping seat 14. The adjustment effect of the clamping seat 14 is achieved by the cooperation between the joints and the sensor 13. At the same time, each joint has multiple degrees of freedom, which can realize all-round and multi-angle flexible movement. The cooperation between the material box 3 and the telescopic rod, the telescopic rod structure and the intelligent balancing system are adapted to various complex environments to ensure the spraying effect at different positions and angles. The cooperation between the connecting rod 6, the movable seat 4 and the sensor 13 is used to achieve a more accurate and stable spraying action, ensure uniform coating thickness, and improve thermal insulation performance. Nanomaterial additives (nano) are added to the spraying material. Nano silicon dioxide (SiO2) and nano zinc oxide (ZnO) enhance the strength, wear resistance and corrosion resistance of the coating, extend the service life of the thermal insulation layer, have certain antibacterial properties, help maintain the sanitary environment inside the cold storage, and have self-repairing materials (polymers containing disulfide bonds) that can repair minor damage in time, prevent damage from expanding, and maintain good thermal insulation effects. Self-repairing materials and more durable structures reduce the frequency and cost of later maintenance and repairs. To ensure the protective effect of the equipment, transparent high-strength protective covers are set outside the key moving parts (universal wheels), electrical components and control interfaces, which can not only protect the internal structure from external interference and damage, but also allow operators to see clearly. To the working state of the robotic arm, the cooperation between the clamping seat 14, the sensor 13 and the connecting rod 6 is utilized to reduce the time of manual spraying work, thereby achieving a protective effect for technicians. Through the use of nanomaterial additives, the quality of spraying is improved. Better spraying quality and durability help to maintain a stable low-temperature environment in the cold storage, reduce energy consumption, and improve the quality and safety of stored items. The searchlight 11 outside the sensor 13 is utilized to make the searchlight 11 move with the movement of the sensor 13. Lighting lamps are installed at the front end and key positions of the robotic arm, which can not only provide sufficient lighting in a dark cold storage environment, facilitate operation and monitoring, but also create a cool visual effect.
