Main functional features

The main controller adopts a 32-bit ARM processor from the 21st century, with processing speed reaching the level of a Pentium class general-purpose computer. Compared with traditional 8-bit microcontroller measurement and control systems, the overall performance is greatly improved, with faster computation speed and higher control accuracy

The data acquisition core device adopts a new type of high-precision 24 bit AD from the United States, with a sampling rate of up to 2000 times per second, which can capture the instantaneous changes in force, and has a resolution of up to 500000 divisions throughout the entire process without any grading. And using 6-point calibration technology to further improve accuracy, the force measurement accuracy is better than the national 0.5 level (advanced) standard.

The displacement encoder adopts a 4-fold counting technology, which increases the displacement resolution by 4 times, reaching up to 0.0005mm.

There are two output control methods, pulse and voltage, which can control any servo motor, variable frequency motor or DC motor with pulse or voltage control interface to achieve smooth and stepless speed regulation. In addition, there are switch signal outputs such as rise, fall and stop that can be used to directly drive external relays or solenoid valves, and can be used to control DC motors or pneumatic, hydraulic and other power devices.

The three loop technology of speed, displacement, and force can achieve precise control of any waveform.

★The company adopts TBI ball screw from Taiwan, China, China, for better transmission accuracy

The transmission efficiency of ball screw pairs is as high as 90% to 98%, which is 2 to 4 times that of sliding screw pairs, and can efficiently convert torque into thrust. The transmission is sensitive, stable, and has low friction resistance, good sensitivity, no vibration during startup, and no crawling at low speeds. It can control micro feed in μ level.

During the transmission process of the ball screw pair with high positioning accuracy, the temperature rise is small, the axial clearance and primary elastic deformation can be eliminated by pre tightening, and the screw can be pre stretched to compensate for thermal elongation, thus achieving high positioning accuracy and repeatability.

Good precision retention, accurate raceway shape, minimal rolling friction and wear, with good precision retention, reliability, and service life.

The high transmission stiffness ball screw pair has eccentric double curved surfaces on both the inner and outer raceways, allowing for flexible transmission even when the clearance between the raceways is extremely small.

The ball screw pair has good synchronization performance due to its high lead accuracy and sensitivity

★YHT adopts Taiwan, China Delta servo drive to better ensure accuracy

Delta Communication Servo MotorThe output power is generally 0.1-1000W, and the power frequency is divided into various types such as 50Hz and 400Hz. It has a wide range of applications, such as being used in various automatic control, automatic recording and other systems

High speed, high response speed, response frequency up to 1kHz; High performance mechanical adaptability can receive pulse commands up to 2Mpps, with a built-in instantaneous speed observer that can quickly and high-resolution detect motor speed

■ Ultra low vibration

1) Adaptive filter, which can automatically adjust the notch filtering frequency according to different mechanical resonance frequencies

2) Two manual notch filters to suppress mechanical resonance

3) Two channel vibration suppression filter is used to suppress mechanical remote vibration in accordance with the ROHS directive, and lead-free soldering is employed

■ Small scale design

1) Miniaturization achieved through thermal analysis of the drive, with a volume of 75% and a weight of 80% compared to the past

2) The new punching process using thin mold steel plates significantly reduces iron loss, shortens motor length (70% of the past), and reduces driver models

advantage:

Good speed control characteristics, smooth control can be achieved throughout the entire speed range, with almost no oscillation;

High efficiency, over 90%, no heat generation; High speed control;

High precision position control;

Realize constant torque within the rated operating area; Low noise;

No wear and tear of electric brushes, maintenance free;

No wear particles, no sparks, suitable for dust-free rooms and explosive environments

★Our company adopts professional processing technology to better ensure quality

Accurate processing technology ensures the coordination between the crossbeam, bearings, and lead screws, reduces errors caused by processing, and further ensures accuracy

The body is treated with spray coating, and the fixtures are equipped with a formal heat treatment process, which is durable and has an authentic appearance

The transmission mechanism inside the bottom box of the whole machine is synchronous belt transmission. Compared with friction type belt transmission, there is no relative sliding between the pulley and the transmission belt of synchronous belt transmission, which can ensure strict transmission ratio. However, synchronous belt transmission requires high center distance and dimensional stability.

Synchronous belt drive has the advantages of belt drive, chain drive, and gear drive. Synchronous belt transmission ensures accurate transmission ratio as there is no relative sliding between the belt and pulley, as the belt and pulley transmit motion and power through meshing

The pulley adopts Mitsubishi high-strength pulley from Japan

The guide rod adopts Japanese SUJ2 precision coaxial chrome plated steel rod

The crossbeam is made of 45 # mold steel and ground

The protective cover is made of professional molded Jianmei aluminum and treated with electrophoretic silver white, with a high-end and elegant appearance that is easy to clean

The dust cover adopts professional plastic cloth dust curtain imported from Taiwan, China, China, to ensure that it will not deform or crack after ten years of use
