What are the key applications of adhesives in industry?
time:2025-08-29 click:Every innovation in the industrial sector isn't about building a tower from scratch, but rather a process of "building a building." From brick to tile, from grain to sand, from bolt to nut, everything needs to be firmly connected.
Recently, the hottest topic is the discussion of which fields AI should replace human labor. While it's premature to discuss AI replacing humans, machines are already replacing human labor in many fields, particularly in industry.
With the surge in global demand for industrial automation, industrial robots are becoming an increasingly important part of the digital ecosystem.
Industrial robots consist of three main parts and six systems, the most important of which are the controller, servo system, and reducer. The controller outputs commands, and the servo system and reducer work together to execute the controller's instructions, ensuring stable and precise operation of the industrial robot.
However, few people are aware of an adhesive that, with its simple process, environmentally friendly materials, and high performance, can ensure long-term stable operation of robots in complex environments.
Industrial robots are composed of numerous precision components. Generally speaking, their operation relies on the coordinated operation of hardware such as the robot body, servo motors, and precision reducers. The reliability and sensitivity of these components not only affect the robot's performance but also directly impact its level of automation. During the critical stages of component manufacturing, assembly, and installation, industrial adhesives, or glue, are required to ensure secure connections between components. If we think of the parts of an industrial robot as our skeleton, then the adhesive is the joints.

Crudely dividing an industrial robot into three parts: the robot body, the drive system, and the control system, we can clearly see how the adhesive tightens the "screws."
To understand the principles behind these three parts, let's first discuss their respective components.
The robot body comprises the base and actuators, such as the robot's arm, wrist, and hand. Some robots also include the walking mechanism.
The drive system consists of two parts: the power unit and the transmission mechanism, with the reducer and servo motor being the core components.
Finally, the control system, generally the "brain" of the industrial robot, issues command signals to the drive system and actuators according to the program we input, thus controlling the robot. Let's discuss the specific applications of adhesives in these areas:
In the gripper units at the actuator and terminal ends, adhesives secure rubber pads and washers, providing stable support and cushioning.
During robotic arm assembly, adhesives also help screws securely install and lock threads, preventing them from loosening or falling out. Special adhesives are used to seal flanges in robotic arms operating in harsh environments, preventing gas or liquid leakage and ensuring stable operation.
In servo motor manufacturing, adhesives firmly bond magnets to silicon steel sheets, providing a stable magnetic field. They also secure coils to prevent movement or falling out during operation.
In precision reducer assembly, adhesives can be used to seal flanges and enhance structural rigidity. They also reduce micro-motion between components, reducing wear and noise, and extending service life.
Compared to traditional mechanical connection methods, industrial adhesives take up virtually no additional space, making them more conducive to miniaturization and lightweight design in the industrial sector. Furthermore, they can connect parts of various materials, shapes, and structures, including metal, plastic, glass, and ceramic.
