Dear friends, have you ever wondered how the servo electric cylinder, a seemingly inconspicuous small component, has emerged in the automation industry and gradually become the core new power?
Next, let's start with the two hottest areas in the world:humanoid robotandnew energy vehicle, start the wonderful journey of servo electric cylinder. We will find that its existence is not only related to the progress of servo technology, but also related to the future of the electric era.
At present, robot manufacturing mainly faces two major constraints: cost and miniaturization. Especially the humanoid robot, its internal structure is very complex, the number of joints is as many as 25-50, and the parts are miniaturized, many types, large amount, and the cost accounts for up to 50% of the whole machine.
Among them, the dexterous hand part has very high requirements for power components. In the past, pneumatic, hydraulic or mechanical methods were generally used as a power source to drive finger activities, which had shortcomings such as unstable operation, low precision, and cumbersome maintenance.
With the development of servo technology, servo motors and servo electric cylinders have gradually replaced pneumatic/hydraulic drive components and become one of the core components of the humanoid robot dexterous hand. Take the value distribution of Tesla's humanoid robot as an example,MiniatureServo electric cylinders (linear actuators) are commonly distributed in high-cost dexterous hands and joints.
The miniature servo electric cylinder mounted on the robot integrates a high-precision reducer, a high-performance hollow cup motor, a screw mechanism, sensors and a servo control system, which ensures a smaller volume.Realize the integration of drive and control, with small size, high precision and large load.And other technical characteristics, so as to achieve the dexterous hand each finger has a "four two dial a thousand pounds" use effect.
▲ Dexterous hand equipped with micro servo electric cylinder
At the same time, the micro-servo electric cylinder also solves the two most troubling problems in the development of dexterous hands-low integration of parts and insufficient miniaturization, and inSignificantly reduce the weight and cost of the dexterous hand while improving its performance and reliability.
In addition to humanoid robots, the application of servo electric cylinders in the field of new energy vehicles is also increasing year by year. Take the adoptionServo press with servo electric cylinder as power sourceFor example, the application covers the fuel cell, power battery, motor, electronic control system and other links of new energy vehicles. For example:
1
In the power battery link
The servo press gives full play to the advantages of high speed and high precision of the servo electric cylinder to assist in the efficient assembly and encapsulation of the battery core, thus ensuring the high quality and long life of the new energy vehicle battery pack.
2
In the motor production link
In the motor production and assembly line, the servo press is widely used to press the bearing to the rotor, press the clamp spring, press the silicon steel sheet to the rotor, press the commutator, press the bearing to the shell, etc. by virtue of the high precision characteristics of the servo electric cylinder. It can not only accurately control the speed and force of the press-fitting process, but also cooperate with the detection of press-fitting force and displacement to achieveAdjustable and controllable parametersThis not only ensures the mass production of motor parts, but also ensures the yield of the motor.
There is also the testing of new energy vehicle parts. Servo electric cylinders play an important role in thrust simulation to ensure that the test is realistic and effective, thereby greatly improving vehicle safety.
1
Detection in brake system
The test mainly simulates the braking process of stepping on the brake pedal in the actual braking process of the vehicle. With the characteristics of closed-loop control, the servo electric cylinder system can easily realize the precise control of thrust, movement speed and displacement, and thenmore accuratesimulation of the braking process of the brake pedal.
2
Static strength testing of headrests in car seats
This test is used to evaluate the ability of the car seat headrest and its fixed structure to resist deformation and damage. The use of servo electric cylinders canAccurately imitate the pressure of the frequency, strength, displacement and other test parametersTo ensure that the test is realistic and effective, so as to ensure that when a rear collision occurs, the headrest can support the passenger's head in a timely and good manner to prevent neck injuries caused by excessive neck corners.
The popularity of servo electric cylinder is not accidental, but inevitable. It is the inevitable product of the electric era and the development of servo technology. This small component is driving the progress of the automation industry with its unique power, and thus changing the way we live and work.
Let's look forward to this new impetus that will bring us more surprises and possibilities in the days to come!
