[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0026] In the description of the present application, “plurality” means two or more, unless otherwise clearly defined.

[0027] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] The present invention realizes the interchangeability of the driving part and the execution part in the mechatronic device by designing a universal action input part and an action output part.

[0029] Combine Figure 1 As shown, a specific embodiment of the present invention discloses a mechatronics simulation system, including multiple drive components 1, multiple simulation action components 2 and a control component 3. Each of the drive components 1 includes a drive unit 11 and an action output unit 12, the drive unit 11 includes an output end, the action output unit 12 is connected to the output end of the drive unit 11 and moves synchronously with the output end of the drive unit 11, the drive modes of the drive units 11 in different drive components 1 are different, and the structural dimensions of the action output units 12 in different drive components 1 are the same. Each of the simulation action components 2 includes an action input unit 21 and an execution component 22, the action input unit 21 is detachably connected to the action output unit 12, and moves synchronously with the action output unit 12 when connected, and the action input unit 21 is transmission-connected to the execution component 22. The control component 3 is electrically connected to the drive unit 11.

[0030] The present invention provides a mechatronics simulation system, which separates the driving part 11 and the execution part in the mechatronics. Multiple groups of different driving components 1 can simulate different driving forms, such as stepper motor drive, servo drive, etc., and multiple groups of different simulation action components 2 can simulate different actuators, such as crank connecting rod, gear transmission, etc. The two are connected through a common action input part 21 and action output part 12, have good interchangeability, can be flexibly combined according to needs, and there is no need to remake the entire mechanism to achieve simulation, which greatly improves experimental efficiency, reduces costs, and has good practicality.

[0031] It should be noted that the present invention only involves the structural part. For the specific control methods in the control component 3, such as algorithms, software, etc., any existing technology can be adopted according to actual needs, and no further explanation will be given in this article.

[0032] In a preferred embodiment, the driving unit 11 is a motor. In practice, the driving unit 11 can also be any existing device with driving capability, such as a push rod, a hydraulic system, etc.

[0033] Combine Figure 2 As shown, in a preferred embodiment, the motor is an AC asynchronous motor. AC asynchronous motors are inexpensive, have high power, strong overload capacity, and are easy to use, install, and maintain. They are widely used in machine tools, textile machines, woodworking machinery, packaging machinery, conveyor lines, and other fields. Therefore, AC asynchronous motors are ideal for simulation, experimentation, and teaching. Considering the power requirements of the laboratory, this embodiment uses a small 220V three-phase asynchronous reduction motor as the drive unit 11. Combined with a Delta MS300 single-phase (220V) inverter, this eliminates the need for a three-phase power supply, requiring only 220V mains power. The Delta MS300 inverter combines the advantages of miniaturization, high functionality, high reliability, and easy installation. Its optimized structure and lockless screw terminal design facilitate wiring and maintenance, saving installation and maintenance time. The user-friendly interface allows for easy parameter configuration by selecting the application. The built-in USB function allows for quick parameter copying, making it extremely convenient to use.

[0034] Furthermore, in another preferred embodiment, the motor is a stepper motor. Unlike conventional AC / DC motors, stepper motors can achieve open-loop control of rotation angle. This means that the angle and speed of the stepper motor are controlled by the number and frequency of pulses input to the driver's signal input terminal, without the need for a feedback signal. Due to their simple control and high reliability, stepper motors are widely used in low-speed control applications (generally below 1000 rpm), such as various small and medium-sized automated equipment and instruments: laser processing equipment, engraving equipment, medical equipment, measuring equipment, electronic processing equipment, and textile and garment equipment. In this embodiment, a Reisai 57HS series two-phase hybrid stepper motor is used in conjunction with a digital medium- and low-voltage stepper motor driver.

[0035] Furthermore, in a preferred embodiment, the motion output unit 12 and the motion input unit 21 rotate synchronously. This synchronous rotation can be achieved through any existing means, such as gears or couplings, while also meeting the requirement for detachability. It is understood that other existing non-rotating connection structures capable of achieving synchronization can also be selected in practice, such as hydraulic mechanisms or connecting rod mechanisms.

[0036] For further information, see Figure 2 、 Figure 3 and Figure 4 In a preferred embodiment, the motion output unit 12 includes an output gear 121, and the motion input unit 21 includes an input gear 211, with the output gear 121 meshing with the input gear 211. Specifically, in this embodiment, the output gear 121 and the input gear 211 are both spur gears, their rotation axes being parallel, and the output gear 121 is fixedly connected to the output end of the motor for synchronous rotation. It is understood that in practice, the motion output unit 12 and the motion input unit 21 may also be implemented using other existing gear devices, such as helical gears.

[0037] In a preferred embodiment, the action output portion 12 further includes an output synchronous pulley 122 and a first connecting portion 123. The output synchronous pulley 122 and the output gear 121 are coaxially arranged, one end face of the output synchronous pulley 122 abuts one end face of the output gear 121, and the first connecting portion 123 is simultaneously connected to the output synchronous pulley 122 and the output gear 121. The action input portion 21 further includes an input synchronous pulley 212 and a second connecting portion 213. The input synchronous pulley 212 and the input gear 211 are coaxially arranged, one end face of the input synchronous pulley 212 abuts one end face of the input gear 211, and the second connecting portion 213 is simultaneously connected to the input synchronous pulley 212 and the input gear 211.

[0038] By simultaneously installing a synchronous belt on the output synchronous pulley 122 and the input synchronous pulley 212, the synchronous rotation of the action output part 12 and the action input part 21 can be achieved, further improving the transmission stability on the basis of the gear transmission. In addition, in this embodiment, the first connecting part 123 and the second connecting part 213 are both bolts, which are connected by passing the bolts through the output synchronous pulley 122 and the output gear 121 at the same time, so that the two can rotate synchronously. Similarly, by passing the bolts through the input synchronous pulley 212 and the input gear 211 at the same time, the connection between the two is achieved, so that the two can rotate synchronously. It is understandable that in practice, the first connecting part 123 and the second connecting part 213 can also be achieved by any existing connecting parts such as AB glue, keys, etc.

[0039] In a preferred embodiment, the output end of the driving unit 11 is coaxially connected to the output gear 121 , and the output synchronous pulley 122 is located at an end of the output gear 121 away from the output end of the driving unit 11 .

[0040] The multiple simulation action components 2 in the present invention can simulate various different functions. For a clearer description, two embodiments of the simulation action components 2 are listed in the present invention:

[0041] Combine Figure 3 As shown, in a preferred embodiment, one of the execution components 22 is a conveying simulation component 221, which includes a bracket 2211, a conveyor belt 2212, and multiple sensor mounting parts 2213. The bracket 2211 includes two crossbeams 22111 and a support 22112. The two crossbeams 22111 are connected to the support 22112. The extension directions of the two crossbeams 22111 are parallel to the running direction of the conveyor belt 2212. The two crossbeams 22111 are connected to the conveyor belt 2212 and are respectively located on both sides of the running direction of the conveyor belt 2212. The conveyor belt 2212 is transmission-connected to the action input part 21, and the sensor mounting part 2213 is connected to the sensor. Multiple sensor mounting parts 2213 are detachably connected to the side of the crossbeam 22111 facing away from the conveyor belt 2212.

[0042] The above-mentioned conveyor belt 2212 is used to simulate the conveyor belt 2212 mechanism in reality, such as the conveyor line in the production line. The transmission roller of the conveyor belt 2212 in this embodiment can be coaxially connected to the input gear 211 to realize transmission.

[0043] Furthermore, in a preferred embodiment, a mounting slot 22113 is defined on the side of the crossbeam 22111 in the bracket 2211 facing away from the conveyor belt 2212. The mounting slot 22113 extends in the same direction as the crossbeam 22111. The sensor mounting portion 2213 is bolted to the mounting slot 22113. The mounting slot 22113 is used to connect multiple sensor mounting portions 2213. Specifically, multiple sensor mounting portions 2213 can be connected at any position using bolts inserted simultaneously into the sensor mounting portion 2213 and the mounting slot 22113 to meet specific experimental needs. In this embodiment, the edge of the mounting slot 22113 has a hem extending inwardly. During implementation, the bolt can be screwed directly into the hem of the mounting slot 22113, or a slider nut with a threaded hole can be inserted into the mounting slot 22113. By adjusting the position of the slider nut, the sensor mounting portion 2213 can be threadedly connected to the crossbeam 22111 at any position.

[0044] As the name suggests, the multiple sensor mounting portions 2213 in this embodiment are used to mount different sensors. The bracket 2211 in this embodiment utilizes a profiled structure, allowing for convenient installation of a variety of sensors, such as infrared reflective sensors, electric worm proximity switches, capacitive proximity switches, and digital encoders. By installing various sensors in the conveyor simulation component 221, simulations of various operating conditions can be achieved, including object counting, object identification and sorting (metal or non-metal), object color recognition, and conveyor line speed measurement.

[0045] Further, combined Figure 4 As shown, in a preferred embodiment, another actuator assembly 22 is a crank slider simulation assembly 222, which includes a base plate 2221, a crank 2222, a connecting rod 2223, a slider 2224, and a guide rail 2225. One end of the crank 2222 is rotatably connected to the base plate 2221 and is transmission-connected to the action input unit 21. The other end of the crank 2222 is rotatably connected to one end of the connecting rod 2223, and the other end of the connecting rod 2223 is rotatably connected to the slider 2224. The crank 2222, the connecting rod 2223, and the slider 2224 constitute a crank 2222-slider 2224 mechanism. It is understood that the crank 2222-slider 2224 structure is an existing technology that can be understood by those skilled in the art. Therefore, the specific connection method, positional relationship, and other technical features between the above-mentioned crank 2222, connecting rod 2223, and other parts will not be described in detail herein. The guide rail 2225 is connected to the bottom plate 2221 . The extension direction of the guide rail 2225 is parallel to the bottom plate 2221 and perpendicular to the rotation axis of the slider 2224 . The slider 2224 is slidably connected to the guide rail 2225 .

[0046] In this embodiment, the crank 2222 is implemented by an eccentric wheel. The midpoint of the eccentric wheel is one end of the crank 2222, which is coaxially and fixedly connected to the input gear 211. The location where the eccentric wheel and the connecting rod 2223 are connected is the other end of the crank 2222. The action input unit 21 drives the crank 2222 to rotate, and the connecting rod 2223 drives the slider 2224 to reciprocate along the guide rail 2225, thus simulating this type of actuator.

[0047] Furthermore, in a preferred embodiment, the slider-crank simulation assembly 222 further includes a distance sensor mounting seat 2226 and a speed sensor mounting seat 2227. The distance sensor mounting seat 2226 is connected to the base plate 2221 and is located on the side of the slider 2224 facing away from the crank 2222. The speed sensor mounting seat 2227 is connected to the base plate 2221 and is located between the slider 2224 and the crank 2222. The distance sensor mounting seat 2226 is used to mount a distance sensor for detecting the displacement of the slider 2224, and the speed sensor mounting seat 2227 is used to mount a speed sensor for detecting the speed of the eccentric wheel (i.e., the crank 2222). This can be used to verify the relationship between the displacement of the slider 2224 and the speed of the crank 2222.

[0048] Furthermore, in a preferred embodiment, the simulated motion component 2 also includes multiple sensors, which are detachably connected to the actuator component 22. Specifically, the multiple sensors can be connected to the sensor mounting portion 2213, the distance sensor mounting seat 2226, and the speed sensor mounting seat 2227. The control component 3 includes an electronic control box, which is electrically connected to the multiple sensors to enable data collection. The electronic control box can be any existing device, such as a PLC control box, an embedded control box, or a computer.

[0049] The present invention provides a mechatronic simulation system, which includes multiple drive components, multiple simulation action components and control components, wherein each of the drive components includes a drive part and an action output part, the drive part includes an output end, the action output part is connected to the output end of the drive part and moves synchronously with the output end of the drive part, the driving mode of the drive parts in different drive components is different, and the structural dimensions of the action output parts in different drive components are the same, each of the simulation action components includes an action input part and an execution component, the action input part is detachably connected to the action output part and moves synchronously with the action output part when connected, the action input part is transmission-connected to the execution component, and the control component is electrically connected to the drive part. The control component controls the driving part, and drives the execution component to move through the action output part and the action input part to realize mechatronics simulation. Compared with the existing technology, the present invention separates the driving part and the execution part in mechatronics. Multiple groups of different driving components can simulate different driving forms, such as stepper motor drive, servo drive, etc., and multiple groups of different simulation action components can simulate different actuators, such as crank connecting rod, gear transmission, etc. The two are connected through a common action input part and action output part, have good interchangeability, and can be flexibly combined according to needs. There is no need to remake the entire mechanism to realize simulation, which greatly improves experimental efficiency, reduces costs, and has good practicality.

[0050] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
