Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a novel ZR motor and its power pneumatic circuit components. Background Technology

[0002] Currently, the ZR robot (linear and rotary motor) is a type of robot that integrates linear and rotary motion functions. It is typically used in industrial applications requiring high precision and repeatability, such as 3C manufacturing, semiconductor processing, and precision assembly. In a ZR robot, the linear motor and rotary motor are separate and installed in different parts of the robot. The linear motor drives the robot's Z-axis linear motion, while the rotary motor drives the robot's R-axis rotation.

[0003] The existing linear rotary motors currently suffer from the following technical problems:

[0004] 1. In the existing technology, the traditional motor structure is loose, the coordination is poor, and the maintenance cost is high. The internal components of the motor (such as power, control, air circuit, etc.) are scattered and lack integrated design, resulting in large component vibration and high energy loss during operation. The housing and cover are mostly fixed connections, which are difficult to disassemble and install. Maintenance requires complete disassembly, which is inefficient.

[0005] 2. Traditional motors use a single control module to centrally manage lifting and power transmission. The signal transmission path is complex and susceptible to interference, resulting in low lifting motion accuracy and response delay. At the same time, the lifting mechanism lacks a linkage detection mechanism between the guide rail and the sensor, which cannot provide real-time feedback of position information. The failure rate is high when multiple components work together.

[0006] 3. Existing gas circuit components mostly adopt a multi-segment pipeline splicing structure, with a large number of interfaces and poor airtightness, which can easily lead to gas leakage and pressure loss; the gas circuit and power components are laid out separately, with long and meandering airflow paths and low energy transmission efficiency. At the same time, the complex structure increases the difficulty of assembly and maintenance costs.

[0007] Therefore, a new type of ZR motor and its power pneumatic circuit components are needed to solve the above-mentioned technical problems. Utility Model Content

By setting a positioning hole on the motor output shaft and utilizing a quick-positioning assembly composed of a fixed base, button, movable shaft, and positioning pin, this invention enables precise circumferential positioning of the motor output shaft.

The magnetic head 23 can change position with the lifting and lowering movement of the power output component. A mounting bracket 24 is provided on one side of the magnetic head 23, and a lifting sensor 25 is provided on the mounting bracket 24 to detect the position of the magnetic head 23 in real time and feed the signal back to the main control board 21 to form a closed-loop control.

[0049] This invention further includes a limiting bracket 16 and a cable management bracket 18 inside the motor housing 1.

[0050] This utility model also discloses a novel power air circuit assembly for a ZR motor, including an air pipe 5, an air connector 3, and an air circuit connecting block 6. One end of the air pipe 5 is connected to the air connector 3, and the other end of the air pipe 5 is connected to the air circuit connecting block 6.

In this utility model, one end of the air pipe 5 is connected to an external air source, and the other end is connected to the air circuit connecting block 6 through the air connector 3, thus achieving air circuit conduction. The air circuit connecting block 6 in this utility model has a hollow internal structure, is fixed to the front end of the upper support 7, and is coaxially arranged with the motor output shaft of the power output assembly. The hollow structure directly connects to the air connector 3, shortening the airflow path, reducing pressure loss, and transmitting airflow power to the motor output shaft, assisting mechanical transmission and improving load response speed.

[0051] Working principle: The working principle of this utility model is as follows: command input → signal hierarchical processing → lifting motion drive and closed-loop regulation → coordinated mechanical and pneumatic power output. Specifically, it includes the following steps:

[0052] 1. Command reception and signal distribution

[0053] External command input: The main control board 21 receives external control signals (such as lifting height command, power output command, etc.).

[0054] Signal hierarchical processing: The main control board 21 parses the lifting command, generates an electrical signal to control the movement of the mover 11, and transmits it to the stator 12 of the lifting transmission assembly via an electrical connection. The sub-control board 20 receives the power output command forwarded by the main control board 21 and independently generates control signals (such as motor start / stop and speed adjustment signals) to drive the power transmission assembly 17.

[0055] 2. Lifting motion control

[0056] The stator 12 generates an electromagnetic field under the signal control of the main control board 21, driving the mover 11 to move linearly along the axial direction. The transmission frame 10 at the front end of the mover 11 moves with the mover 11, driving the transmission connecting block 15 to push the slider 14 of the lifting mechanism to slide along the linear guide rail 13. The linear guide rail 13 provides high-precision guidance to ensure the linearity of the slider 14's movement trajectory; the support block limits the upper limit position of the slider 14 to prevent overtravel. The magnetic head 23 changes position with the lifting movement of the upper support member 7 and the lower support member 8. The lifting sensor 25 detects the position of the magnetic head 23 in real time and generates a feedback signal. The main control board 21 dynamically adjusts the drive current of the mover 11 according to the feedback signal, corrects the lifting stroke error, forms a closed-loop control, and ensures lifting accuracy.

[0057] 3. Power output and air system assistance

[0058] The power transmission assembly 17 is started under the control of the sub-control board 20, transmitting mechanical power to the motor output shaft of the power output assembly via the drive shaft. The motor output shaft transmits power to the external load, driving the load to perform rotational or linear motion. An external air source supplies compressed gas to the air connection block 6 through the air pipe 5 and the air connector 3. The hollow structure of the air connection block 6 directly guides the airflow to the motor output shaft. The airflow drives the motor output shaft to rotate or provides auxiliary thrust, enhancing the power response speed and reducing wear on mechanical transmission components during sudden load changes.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
