Mechatronics technology equipment description
1. Competition equipment description
The competition platform is mainly composed of a pellet feeding unit, a capping and screwing unit, a detection and sorting unit, a robot handling and packaging unit, an intelligent warehousing unit, etc. It can realize empty bottle loading, pellet material loading, material sorting, pellet filling, The entire intelligent production process includes capping, capping, material detection, bottle cap detection, finished product sorting, robot picking into boxes, lid packaging, labeling, and warehousing.
2. Overview of work process
The working process of this system is summarized as follows:
(1) The conveying mechanism of the particle feeding unit conveys the empty bottles to the feeding conveyor belt. The empty bottle in-position detection sensor detects the empty bottle, and the conveying mechanism stops. The loading conveyor belt transports the empty bottles to the main conveyor belt. When the empty bottles reach the filling position, the filling positioning mechanism fixes the empty bottles and the main conveyor belt stops; at the same time, the feeding mechanism pushes out the corresponding color materials according to the task requirements; the filling mechanism Suction the granular materials in place and put them into the empty material bottle; after the filling material in the material bottle reaches the set number of particles, the filling and positioning cylinder is released, and the main conveyor belt is started to transport the material bottle to the next station.
(2) The material bottle is transported to the capping mechanism of the capping and capping unit. The capping and positioning mechanism fixes the material bottle. The capping mechanism starts the capping process and adds the cap (white or blue) to the material bottle; The capped material bottle is then sent to the capping mechanism. When it reaches the bottom of the capping mechanism, the capping positioning mechanism fixes the bottle, and the capping mechanism starts to tighten the cap.
(3) The capped material bottles are inspected by the detection and sorting unit: the feed detection sensor detects whether the capped material bottles are in place, and the retroreflective sensor detects whether the caps are tightened; the detection mechanism detects whether the particles inside the material bottles meet the requirements ; Material bottles with qualified caps and pellets are distinguished by cap color; bottles with unqualified caps or pellets are pushed to different waste storage areas by the sorting mechanism; bottles with qualified caps and pellets are Transported to the end of the main conveyor belt, waiting for robot handling.
(4) The two lifting table mechanisms of the robot handling and packaging unit store packaging boxes and packaging box lids; lifting table A pushes the packaging boxes to the material table; the 6-axis robot grabs the material bottles and puts them into the packaging boxes on the material table; After the 4 stations of the packaging box are filled with material bottles, the 6-axis robot picks up the box lids from the lifting table B and puts them on the packaging box; the 6-axis robot labels the bottle caps according to their colors, and notifies the smart phone after attaching the 4 labels. Storage unit storage.
(5) The stacking mechanism of the intelligent storage unit can move and rotate to take out the packaging boxes from the material table of the robot unit, and then put them into the corresponding storage positions in sequence as required.
Module 1 Mechanical disassembly and electrical wiring of the work unit
Task situation:
The company received a customized equipment task from a customer and needed to deliver a set of automated production line equipment within a specified time. The company's project team carried out an overall planning and design of the equipment. As a mechatronics technician, you need to use the devices and materials purchased by the customer. , please complete Task 1, Task 2, and Task 3 within the specified time, so that the production process can be automated later in the production line and the system meets professional technical specifications. After the contestant completes or submits the paper, no modifications are allowed. Any hardware problems that arise during the scoring stage can be solved in subsequent work tasks.

work tasks:
The mechanical parts of the pellet filling mechanism are damaged due to long-term operation of the pellet unit, and the mechanical drawings of the equipment are lost. Please conduct surveying and mapping based on the existing damaged parts, draw the 3D drawings and parts engineering drawings of the parts in the 3D design software, and add them to the given numbers. The twin system realizes the simulation operation of the workstation and verifies the designed parts.
device status:
Because the picking arm of the particle filling mechanism is broken, the picking cannot be carried out.
(2) Task content
1. Mechanical structural design of parts
Please conduct surveying and mapping based on the existing damaged parts, draw the 3D diagram of the part and the engineering drawing of the part in the 3D design software, save the 3D diagram of the part in the format of "Competition Number.Step", and export the file in 3D pdf format "Competition Number.pdf" ; The design of parts engineering drawings should comply with the relevant technical standards of GB mechanical drawing. The design elements include part structure, general dimensions, dimensional accuracy, surface roughness and surface treatment technical requirements, and should be saved as "competition number.dwg". The above three files are saved in the "D:\Skills Competition\Competition Number" folder.
2.Digital twin simulation and verification
Use the designed part model and the provided 3D model of the pellet feeding unit to import it into the given digital twin system to complete the modeling of the pellet feeding unit. Add corresponding attributes and actions according to the functions of the twin device to realize the virtualization of the pellet feeding unit. Simulation is run to verify the designed parts, and virtual and real linkage with the particle loading unit is realized in the second link of the module. The relevant virtual device signal names and functions are configured according to the signal function allocation table. Signal names not included in the table are planned by yourself. Virtual simulation and virtual-real linkage simulation scenes are saved separately. The virtual simulation scene file is saved as virtual simulation+station number.vmcx, and the virtual-real linkage scene simulation file is saved as virtual-real linkage+station number.vmcx. Both simulation files are saved in "D :\Skills Competition\Competition Number" folder.

仿真运行流程要求：
运行仿真，推料气缸A连续推出1颗白色物料；完成后推料气缸B再推出3颗蓝色物料；当白色或蓝色物料到达取料位后，等待颗粒填装机构取料；填装机构下降，吸住物料；填装机构上升后填装机构转向装料位。仿真开始运行的同时，圆盘输送机构开始输送瓶子，当空瓶到位检测传感器检测到空瓶时（每次只出一个空瓶），圆盘输送机构停止；上料输送带将空瓶输送到主输送带；当颗粒填装位检测传感器检测到空瓶，填装定位气缸伸出，将空瓶固定；填装机构下降吸盘关闭，物料顺利放入瓶子；填装机构上升并转向取料位；当瓶子装满4颗物料，填装定位气缸缩回；将瓶子输送到下一工位；开始循环填装下一个瓶子。
