Description

Technical Field

[0001] The present invention relates to the technical field of motor maintenance, and particularly to a motor maintenance line and a maintenance method. Background Art

[0002] In the field of modern railway transportation, the stable operation of bullet trains is crucial. As a key component of bullet trains, the fan motor plays an indispensable role in the heat dissipation of traction motors. With the increase in the driving mileage and time of bullet trains, the regular maintenance of fan motors has become an important link to ensure the safe and reliable operation of bullet trains.

[0003] However, for the maintenance method of fan motors, the traditional fixed-station operation method requires different tools to be taken at a single position to complete the maintenance processes such as stator and rotor disassembly, cleaning, measurement, rotor bearing press-fitting, stator and rotor assembly, and motor whole-machine testing. This method is not only inconvenient to operate, but also the frequent taking of tools increases the operation time and labor intensity, and the efficiency is extremely low. The method of multi-station operation and using a crane for station transfer, although dispersing the operation links to a certain extent, has many limitations and risks in the use of the crane. The operation of the crane requires professional personnel, and the station transfer process takes a long time, which not only affects the maintenance efficiency but also increases the potential safety hazards. In addition, frequent crane operations will also cause certain interference and damage to the operation environment.

[0004] In summary, the existing fan motor maintenance technologies, whether it is the fixed-station operation method or the multi-station crane transfer operation method, have problems such as low efficiency and backward operation mode, and are difficult to meet the requirements of modern railway transportation for high-efficiency, safe, and high-quality maintenance of fan motors. Summary of the Invention

[0051] Embodiment 1

[0052] See Figures 1 to 10 , the motor overhaul line provided by the embodiment of the present invention includes a conveying assembly 1, a material loading assembly 2, a transfer assembly 3, a lifting assembly 4 and a limiting assembly 5. Among them, the conveying assembly 1 includes a plurality of processing lines 12 and two conveying lines 11 arranged at intervals in the vertical direction. The conveying directions of the two conveying lines 11 are opposite. The processing lines 12 extend in a direction perpendicular to the conveying lines 11, and the processing lines 12 are correspondingly connected to the conveying lines 11. The plurality of processing lines 12 are arranged along the extending direction of the conveying lines 11; the material loading assembly 2 is used for loading the motor to be repaired, and the material loading assembly 2 is detachably connected to the conveying line 11, and the material loading assembly 2 can move along the conveying direction on the conveying line 11; the transfer assembly 3 is arranged at the connection of the conveying line 11 and the processing line 12 and is used for transferring the material loading assembly 2 between the conveying line 11 and the processing line 12; the lifting assembly 4 is arranged at both ends of the conveying direction of the conveying line 11 and is used for switching the material loading assembly 2 between the two conveying lines 11; the limiting assembly 5 is arranged on the conveying line 11, and the limiting assembly 5 is used for limiting and fixing the material loading assembly 2 conveyed on the conveying line 11.

[0053] The motor maintenance line proposed by the present invention realizes the reasonable planning and zoning of the motor maintenance process through the cooperation of the conveying assembly 1, multiple processing lines 12 and two conveying lines 11. Different processes can be carried out orderly on specific lines, avoiding cross-interference between processes and improving the overall work efficiency. The material-carrying assembly 2 can move along the conveying direction on the conveying line 11, ensuring that the motor can be transported to each maintenance station smoothly and accurately, avoiding bumps and damages during manual handling, and ensuring the safety of the motor. The transfer assembly 3 can accurately and quickly transfer the material-carrying assembly 2 between different lines, reducing the transfer time and error, and improving the coherence and efficiency of the work. The lifting assembly 4 can realize the smooth switching of the material-carrying assembly 2 between the two conveying lines 11, enabling the upper and lower conveying lines 11 to work in coordination. The limiting assembly 5 can accurately limit and fix the material-carrying assembly 2 on the conveying line 11, ensuring the stability and safety of the motor during loading and unloading operations at specific positions. The embodiment of the present invention realizes the automatic flow during the motor maintenance process through the automated conveying line 11, avoiding the low efficiency of traditional manual handling and fixed-station operations, and shortening the maintenance time.

[0054] The specific structure of the motor maintenance line will be described below.

[0055] See Figure 2 , the conveying assembly 1 is used to realize the conveying and processing process of the motor to be repaired through the cooperation of the conveying line 11 and the processing line 12. Regarding the conveying line 11, the conveying assembly 1 further includes a first driving motor 13, a transmission gear 14 and a double-speed chain 15. The transmission gear 14 is coaxially connected to the motor shaft of the first driving motor 13, and the double-speed chain 15 is meshed with the transmission gear 14. The double-speed chain 15 extends along the length direction of the conveying line 11. The first driving motor 13 can provide continuous and reliable power output to ensure the normal operation of the conveying line 11. The double-speed chain 15 can adapt to different load and conveying speed requirements, improving the flexibility and versatility of the conveying line 11. Through the cooperation of the first driving motor 13, the transmission gear 14 and the double-speed chain 15, the speed of the conveying line 11 is accurately controlled to meet the requirements of different maintenance processes for the conveying rhythm of the motor, further improving the work efficiency and accuracy of the entire motor maintenance line.

[0056] See Figure 3 , the processing line 12 includes a back panel 121, a workbench surface 122, a support frame 123 and a docking station 124. The back panel 121 is provided with panels such as lighting, power strips and switch lights. The workbench surface 122 is provided with bull's-eye bearings, which facilitate the manual dragging of the material-carrying assembly 2 to the working position after it flows in. The support frame mainly realizes the fixation of the operation workbench. The docking station 124 mainly realizes the automatic positioning of the material-carrying assembly 2 coming from the conveying line 11.

[0057] Specifically, the processing line 12 further includes a lower-layer return line, which consists of a driving member, a driving chain, and a blocking mechanism. The driving member adopts a driving sprocket and a driven sprocket driven by a motor. The driving sprocket is connected to the driving motor through a coupling. The driving motor is an AC asynchronous motor, which can provide a stable rotational speed and a large torque. The driving chain is made of high-strength engineering plastic material. The links between the chain links are closely connected, and it has good wear resistance and corrosion resistance. The driving chain surrounds the driving sprocket and the driven sprocket to form a closed loop. The blocking mechanism consists of a cylinder, a baffle, and a position sensor. The position sensor is installed at a specific position on the return line to detect the arrival of the material-carrying component 2. When the position sensor detects the material-carrying component 2, it sends a signal to the cylinder. After receiving the signal, the cylinder drives the baffle to extend, blocking the material-carrying component 2 from moving forward, thereby realizing the control of the flow rhythm of the material-carrying component 2.

[0058] In addition, to facilitate the transfer of the material-carrying component 2 between the conveyor line 11 and the processing line 12 by the transfer component 3. A plurality of guide rollers 125 are provided on the connection table 124. The guide rollers 125 can rotate along their circumferences. The plurality of guide rollers 125 are arranged at intervals along the extension direction of the processing line 12. Thus, the transfer of the material-carrying component 2 between the conveyor line 11 and the processing line 12 is facilitated through the arrangement of the guide rollers 125.

[0059] See Figure 4 and Figure 5 , the transfer component 3 includes a transmission mechanism 31. The transmission mechanism 31 includes a second driving motor 311, a transfer gear 312, a gear shaft 313, and a transmission chain 314. A transfer gear 312 is provided at each end of the gear shaft 313. A transmission chain 314 is meshed and connected to each corresponding transfer gear 312. The transmission chain 314 is used to transport the material-carrying component 2. The two transmission chains 314 are arranged at intervals and extend in a direction perpendicular to the conveyor line 11. The gear shaft 313 is connected to the motor shaft of the second driving motor 311. During use, the second driving motor 311 drives its own motor shaft to rotate, thereby driving the coaxial connected motor shaft to rotate synchronously, driving the transfer gears 312 at both ends of the motor shaft to rotate, and driving the transmission chain 314 to move in the rotation direction of the transfer gear 312, so that the material-carrying component 2 connected to the transmission chain 314 moves.

[0060] It can be understood that during actual use, the rotation direction of the motor shaft of the second driving motor 311 can be adjusted according to the direction in which the material-carrying component 2 needs to move.

[0061] Further, the transfer assembly 3 further includes a lifting mechanism 32. The lifting mechanism 32 includes a lifting member 321 and a bottom plate 322. The lifting member 321 is disposed on the conveyor line 11 and can expand and contract in the vertical direction. The bottom plate 322 is connected to the telescopic end of the lifting member 321, and the transmission mechanism 31 is disposed on the bottom plate 322. The lifting member 321 can expand and contract in the vertical direction, so that when transferring the material-carrying assembly 2, the material-carrying assembly 2 can be first lifted to an appropriate height to avoid interference with the conveyor line 11 or other components, ensuring the smoothness and safety of the transfer process.

[0062] The bottom plate 322 is connected to the telescopic end of the lifting member 321, providing a stable installation platform for the transmission mechanism 31. During the lifting process, the entire transmission mechanism 31 can rise together with the bottom plate 322, ensuring the accurate docking of the transmission mechanism 31 with the material-carrying assembly 2 and improving the accuracy and reliability of the transfer. Through the cooperation of the lifting mechanism 32 and the transmission mechanism 31, precise control of the material-carrying assembly 2 in the vertical direction is achieved, further improving the automation level and working efficiency of the entire motor maintenance line. In this embodiment, the lifting member 321 is a hydraulic cylinder. The hydraulic cylinder is composed of a cylinder barrel, a piston, a piston rod, end caps, and seals. The inside of the cylinder barrel is filled with hydraulic oil. The piston is installed in the cylinder barrel and connected to the piston rod. When the hydraulic oil enters the cylinder barrel through the oil inlet, it pushes the piston to move, thereby driving the piston rod to extend. The cylinder barrel of the hydraulic cylinder is fixedly installed on the bottom frame of the conveyor line 11. The top end of the piston rod is connected to the bottom plate 322. In other embodiments, the lifting member 321 can also be an electric pump, an electric push rod, etc., which will not be elaborated here.

[0063] Furthermore, the transfer assembly 3 further includes a mounting frame 33, guide posts 34, and an RFID tag reader 35. The mounting frame 33 is made of a metal material and is generally rectangular in shape, providing a stable installation space for the lifting member 321. There are four guide posts 34, and the two ends are respectively connected to the bottom plate 322 and the mounting frame 33, which are used to ensure the stability of the bottom plate 322 during the lifting process. At the same time, the RFID tag reader 35 can read the RFID tag information carried on the material-carrying assembly 2 and transmit the relevant data to the control system for identifying and tracking management of the material-carrying assembly 2 and the motor it carries.

[0064] It can be understood that the RFID tag reader 35 is an existing device in the art, and its working principle and specific structure will not be elaborated here.

[0065] See Figure 6, the lifting assembly 4 is used to switch the material-carrying assembly 2 between the two conveyor lines 11. Specifically, the lifting assembly 4 includes a jacking cylinder 41, a lifting mechanism 42, and a bearing pallet 424. The bearing pallet 424 is used to carry the material-carrying assembly 2. The lifting mechanism 42 is connected to the bearing pallet 424, and the jacking cylinder 41 is connected to the lifting mechanism 42. The jacking cylinder 41 can drive the lifting mechanism 42 to lift and lower in the vertical direction, thereby driving the bearing pallet 424 to lift and lower in the vertical direction. The lifting mechanism 42 connects the bearing pallet 424 and the jacking cylinder 41, and can accurately convert the linear motion of the jacking cylinder 41 into the vertical lifting motion of the bearing pallet 424, ensuring the smoothness and accuracy of the lifting process, and making the switching position of the material-carrying assembly 2 between the two conveyor lines 11 accurate without error.

[0066] Specifically, the lifting mechanism 42 includes a third drive motor 421, a lifting gear 422, and a lifting chain 423. The motor shaft of the third drive motor 421 extends in the horizontal direction. The lifting gear 422 is coaxially arranged with the motor shaft of the third drive motor 421. The lifting chain 423 meshes with the lifting gear 422 and is connected to the bearing pallet 424, so that the lifting force can be evenly distributed on the bearing pallet 424, ensuring the levelness and stability of the bearing pallet 424 during the lifting process, and preventing the material-carrying assembly 2 from tilting or shaking.

[0067] In addition, the lifting assembly 4 further includes a frame mechanism 43, a guiding track 44, and a track base 45. The frame mechanism 43 is mainly built with aluminum profiles to provide an installation space for the lifting mechanism 42 and the bearing pallet 424, and is fixed to the ground by bolts. The guiding track 44 is connected to the frame mechanism 43. There are two guiding tracks 44, and the two guiding tracks 44 are arranged at intervals. The bearing pallet 424 is slidably connected to the guiding track 44. The track base 45 is arranged at the bottom of the guiding track 44 and is configured to support the guiding track 44.

[0068] Moreover, a pallet transmission structure 46 is further provided on the bearing pallet 424. Specifically, the pallet transmission structure 46 is composed of a small DC motor, a transmission belt, and a transmission shaft. The small DC motor is fixed on one side edge of the bearing pallet 424, and its motor shaft is connected to the transmission shaft through a coupling. The transmission shaft is arranged along the width direction of the bearing pallet 424, and transmission wheels are respectively installed at both ends and the middle position of the transmission shaft. The transmission belt is wound around the transmission wheels to form a closed transmission loop. When the jacking cylinder 41 drives the bearing pallet 424 to rise or fall in place, the small DC motor starts, driving the transmission shaft to rotate, thereby making the transmission belt move. The material-carrying assembly 2 is placed on the transmission belt, and the material-carrying assembly 2 is driven to move horizontally on the bearing pallet 424 through the friction force of the transmission belt, so as to accurately position it at the required position, or smoothly push it onto the corresponding conveyor line 11.

[0069] Furthermore, the tray transmission structure 46 further includes a guiding frame, and the end of the guiding frame is provided with an inclination to facilitate the inflow of the material-loading component 2. When the material-loading component 2 moves from the conveyor line 11 to the carrying pallet 424, the inclination at the end of the guiding frame plays a guiding role, enabling the material-loading component 2 to smoothly flow into the carrying pallet 424. Driven by the tray transmission structure 46, the material-loading component 2 moves smoothly along the inner side of the guiding frame until it reaches the designated position, preparing for the lifting operation.

[0070] See Figure 7 , the limiting component 5 is used to limit and fix the material-loading component 2 conveyed on the conveyor line 11. The limiting component 5 includes a sensor 51 and a telescopic member 52. The sensor 51 and the telescopic member 52 are electrically connected. The sensor 51 is used to detect the position of the material-loading component 2. When the material-loading component 2 reaches the target position, the telescopic member 52 extends and connects with the material-loading component 2, thereby realizing the limitation of the material-loading component 2. The sensor 51 can accurately detect the position of the material-loading component 2 and timely feedback its position information, ensuring the accurate monitoring of the position of the material-loading component 2, and providing a timely and accurate judgment basis for the subsequent limiting operation. The telescopic member 52 is electrically connected to the sensor 51, realizing an automated response. When the sensor 51 detects that the material-loading component 2 reaches the target position, the telescopic member 52 can quickly extend and connect with the material-loading component 2, realizing fast and effective limitation.

[0071] Specifically, the sensor 51 adopts a photoelectric sensor, which is installed on the side of the conveyor line 11 and is at a certain distance in front of the target position. The emitter and receiver of the photoelectric sensor are respectively located on both sides of the conveyor line 11. When the material-loading component 2 passes through, it will block the light, thereby triggering a detection signal. The telescopic member 52 adopts an electric push rod, which is fixed above the conveyor line 11 through a bracket. The telescopic end of the electric push rod faces downward, and a rubber pad is installed at the end to increase the friction and buffering when contacting the material-loading component 2. The electric push rod is electrically connected to the photoelectric sensor through a controller. When the photoelectric sensor detects that the material-loading component 2 reaches the target position, it sends a signal to the controller, and the controller then controls the electric push rod to extend. The telescopic end of the electric push rod quickly extends, and the rubber pad at its end contacts the material-loading component 2 and applies pressure, thereby realizing the limitation and fixation of the material-loading component 2.

[0072] See Figure 8, the material loading component 2 is used to load the motor to be repaired and drive the motor to be repaired to move on the conveyor line 11. In order to facilitate the classification and storage of various parts after the motor to be repaired is disassembled, so as to facilitate subsequent maintenance and processing and improve work efficiency. The material loading component 2 includes a rotor tray 21, and the rotor tray 21 includes a first chassis 211, a first rotating disk 212 and a rotor storage rack 213. A first rotating disk 212 is arranged on the first chassis 211, and the first rotating disk 212 can rotate along its own circumferential direction. The rotor storage rack 213 is arranged on the first rotating disk 212 and is used to configure the rotor equipment. The first chassis 211 provides a stable basic support for the entire rotor tray 21. The first rotating disk 212 can rotate along its own circumferential direction, enabling the operator to conveniently adjust the angle and position of the rotor during maintenance without moving the entire tray, improving the convenience and flexibility of the operation. The rotor storage rack 213 is arranged on the first rotating disk 212, providing a dedicated storage position for the rotor equipment, which can effectively fix and protect the rotor, preventing collision and damage during transportation and operation; at the same time, it makes the taking and placing of the rotor more convenient and accurate, improving work efficiency and safety.

[0073] Specifically, a limiting groove 25 is formed on the first chassis 211, and the limiting groove 25 is used to cooperate with the telescopic member 52 of the limiting assembly 5. By providing the limiting groove 25, a clear cooperation position can be provided for the telescopic member 52, ensuring that the telescopic member 52 can accurately dock with the first chassis 211 when extending for the limiting operation, avoiding the situation of limiting failure or instability caused by inaccurate docking. The cooperation between the limiting groove 25 and the telescopic member 52 is closer and more precise, enhancing the reliability and stability of the limit.

[0074] It can be understood that the setting position and the number of the limiting grooves 25 are not limited herein and can be adjusted adaptively according to actual needs.

[0075] Specifically, guide wheels 24 are arranged on the outer periphery of the first chassis 211, and the guide wheels 24 can contact the conveyor line 11. The guide wheels 24 can reduce the friction between the first chassis 211 and the conveyor line 11, make the movement of the material loading component 2 on the conveyor line 11 smoother, reduce the energy consumption during the conveying process, and improve the conveying efficiency. The contact between the guide wheels 24 and the conveyor line 11 increases the stability and balance of the movement of the material loading component 2, reduces the possibility of shaking and deviation, thereby ensuring the safety of the motor on the material loading component 2 and reducing the risk of damage to the motor caused by instability.

[0076] See Figure 9In addition to the rotor tray 21, the loading assembly 2 also includes a stator tray 22. The stator tray 22 includes a second chassis 221, a second turntable 222 and a motor positioning mechanism 223. The second chassis 221 provides a solid foundation, ensures the stability of the stator on the tray, and reduces the risk of shaking during transportation and operation. The second turntable 222 can rotate, so that the position and angle of the stator can be flexibly adjusted according to maintenance requirements, which is convenient for operators to perform maintenance operations from different directions, improving the convenience and efficiency of operation. The motor positioning mechanism 223 can accurately position and fix the stator to prevent the stator from shifting on the tray, ensuring that the position of the stator is always accurate during the maintenance process, which helps to improve the accuracy and quality of maintenance.

[0077] In addition, see Figure 10 The loading assembly 2 further includes a parts tray 23, and the parts tray 23 includes a third chassis 231 for storing accessories such as a terminal box, an impeller, and an impeller cover that are disassembled from the motor to be repaired.

[0078] It is understandable that the stator tray 22 and the parts tray 23 are also provided with guide wheels 24 and limiting grooves 25 accordingly, which will not be described in detail here.

[0079] Embodiment 2

[0080] The embodiment of the present invention further provides a motor maintenance line method, which uses the above-mentioned motor maintenance line and includes:

[0081] First, the material loading assembly 2 flows from the buffer position of the processing line 12 located at the lower layer to the conveying line 11 located at the lower layer.

[0082] Among them, the cache position is located in the lower return line of the processing line 12, and the carrier component 2 on the processing line 12 controls the flow rhythm of the carrier component 2 through the cooperation of the transmission parts, transmission chain and blocking mechanism in the lower return line.

[0083] After the loading component 2 flows to the conveying line 11 located on the lower layer, the loading component 2 is transported to the end of the conveying line 11 located on the lower layer through the conveying line 11 to cooperate with the lifting component 4, and the loading component 2 is lifted to the conveying line 11 located on the upper layer through the lifting component 4.

[0084] Specifically, the loading assembly 2 flows into the carrying pallet 424 under the guidance of the inclination of the end of the guide frame, and then driven by the tray transmission structure 46, the loading assembly 2 moves smoothly along the inner side of the guide frame until it reaches the specified position, ready for lifting operation.

[0085] Specifically, the telescopic end of the lifting cylinder 41 extends in the vertical direction, driving the bearing tray 424 to move in the vertical direction, and simultaneously driving the material loading assembly 2 located on the bearing tray 424 to rise synchronously. Moreover, through the cooperation of the driving motor, the lifting gear 422, and the lifting chain 423, the bearing tray 424 can be finely adjusted in the height direction, so as to ensure that the position of the material loading assembly 2 is adjusted in place, and the material loading assembly 2 is transported to the conveyor line 11 through the tray transmission structure 46.

[0086] After the material loading assembly 2 is transferred to the upper-layer conveyor line 11, through the cooperation of the first driving motor 13, the transmission gear 14, and the double-speed chain 15 in the conveying assembly 1, the material loading assembly 2 to be transferred is driven to move along the conveyor line 11.

[0087] When the material loading assembly 2 flows to the first set position, the limiting assembly 5 limits the material loading assembly 2, places the motor to be repaired on the material loading assembly 2, and then releases the limit.

[0088] Specifically, when the material loading assembly 2 flows to the first set position, the photoelectric sensor detects that the material loading assembly 2 reaches the target position, sends a signal to the controller, and the controller immediately controls the electric push rod to extend. The telescopic end of the electric push rod quickly extends and is clamped with the limiting groove 25, thereby realizing the limiting and fixing of the material loading assembly 2. Then, the motor to be repaired is manually lifted and placed on the tray.

[0089] The material loading assembly 2 is transported along the conveyor line 11, and the material loading assembly 2 is transferred to the processing line 12 through the transfer assembly 3 for overhaul operation on the motor to be repaired. After all the overhaul operations are completed, the material loading assembly 2 is transferred back to the conveyor line 11 through the transfer assembly 3.

[0090] Specifically, in this embodiment, the processing line 12 is divided into a disassembly station, a cleaning station, an inspection station, and an assembly station along the extension direction of the conveyor line 11.

[0091] First, the material loading assembly 2 is transported along the conveyor line 11. When the material loading assembly 2 faces the disassembly station, it stops moving. The material loading assembly 2 is transferred to the disassembly station through the transfer assembly 3. The operator disassembles the whole motor. The disassembled rotor is placed on the rotor tray 21, the disassembled loose parts are placed on the loose parts tray 23, and the disassembled stator is placed on the stator tray 22.

[0092] After that, the rotor tray 21, the stator tray 22, and the loose parts tray 23 are respectively transferred to the conveyor line 11 through the transfer mechanism and continue to be transported along the conveyor line 11.

[0093] When the material loading assembly 2 faces the cleaning station, it stops moving. The material loading assembly 2 is transferred to the cleaning station through the transfer assembly 3 for cleaning operation.

[0094] After that, the rotor tray 21, the stator tray 22, and the loose parts tray 23 are respectively transported to the conveyor line 11 by the transfer mechanism and continue to be transported along the conveyor line 11.

[0095] When the material-carrying assembly 2 faces the detection station, it stops moving, and the material-carrying assembly 2 is transported to the detection station by the transfer assembly 3 for detection operations.

[0096] After that, the rotor tray 21, the stator tray 22, and the loose parts tray 23 are respectively transported to the conveyor line 11 by the transfer mechanism and continue to be transported along the conveyor line 11.

[0097] When the material-carrying assembly 2 faces the assembly station, it stops moving, and the material-carrying assembly 2 is transported to the assembly station by the transfer assembly 3 for assembly operations.

[0098] Among them, the assembly station is divided into a first assembly station and a second assembly station. The first assembly station only calls the rotor tray 21 and the loose parts tray 23 for pre-assembling the rotor, and the second assembly station only calls the stator tray 22 for pre-assembling the stator.

[0099] Then, the stator and the rotor are assembled together, and the assembled motor is placed on the stator tray 22 at the second assembly station by using a crane.

[0100] After that, the stator tray 22 is transported to the conveyor line 11 by the transfer mechanism and continues to be transported along the conveyor line 11.

[0101] When the material-carrying assembly 2 flows to the second set position, the limiting assembly 5 limits the material-carrying assembly 2 and takes out the motor to be repaired that has completed the repair operation, and then releases the limit.

[0102] Specifically, after the assembled stator tray 22 is transferred to the second set position, the motor is lifted down and transported to the test room by an AGV transport vehicle for experiments.

[0103] After that, the lifting assembly 4 lowers the material-carrying assembly 2 to the conveyor line 11 on the lower layer.

[0104] After that, the material-carrying assembly 2 flows from the conveyor line 11 on the lower layer into the buffer position of the processing line 12 on the lower layer for convenient use next time.

[0105] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed.
