Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Provided by Figures 1 - 9 The present utility model provides a double-layer four-station roller AGV conveying device, including two equipment racks 1, the equipment racks 1 are installed on the top of the chassis 2, a roller conveyor line module 3 is installed between the equipment racks 1, a drive assembly 21, a balance wheel assembly 22 and an obstacle avoidance lidar 23 are respectively installed on the top of the chassis 2, the roller conveyor line module 3 includes two conveying tables 31 installed between the equipment racks 1, the conveying tables 31 are connected by steel plates, the lower conveying table 31 is fixed to the top of the chassis 2 through two supports 34, a middle partition board 32 is fixed to the top of the conveying table 31, electric rollers 33 are installed on the inner walls of the two sides of the middle partition board 32 and the conveying table 31, grooves are provided above the conveying tables 31 on the inner sides of the two equipment racks 1, and roller control optoelectronics 4 are installed inside the grooves.

[0025] By designing the roller conveyor line module 3, during operation, the two conveyor platforms 31 are placed on the two brackets 34 at the top of the chassis 2 between the equipment racks 1 and fixed. A total of four groups of electric rollers 33 are provided on both sides of the upper and lower middle partitions 32. Each group of electric rollers 33 can be designed with a single electric roller 33 driven electrically and driving the remaining several idler rollers through a multi-wedge belt, thus saving electrical energy. When transporting, the bin equipment is located on one side of the conveyor line, and the bin automatically moves onto the four groups of electric rollers 33. At the same time, there are three roller control photoelectric sensors 4 on one side of each group of electric rollers 33, which are used to monitor and control the operating state of the rollers, including parameters such as speed, position, and load. After the trolley receives the bin, it will detect the signal of the roller control photoelectric sensor 41. When the middle photoelectric sensor is triggered, the roller conveyor line on the trolley decelerates. When the third photoelectric sensor is triggered, the roller conveyor line of the trolley stops. Then the trolley completes the docking task and realizes automatic docking and loading, which is very practical. After that, it is displaced by the driving component 21, and the balance wheel component 22 can assist in the movement. An obstacle avoidance lidar 23 is installed on the trolley, which can effectively enable the trolley to detect obstacles, thus preventing collisions, and then completing the transportation. In this way, relying on the multi-station conveyor line, multiple bins can be transported simultaneously to complete the transportation task, which can reduce the transportation cost and improve the transportation efficiency.

[0026] The driving component 21 includes a first universal wheel 211, a servo motor 212, a driving wheel 213, and a fixed support 214. The first universal wheel 211 and the driving wheel 213 are fixed on a connecting member, and the connecting member is rotatably connected to the first fixed support 214. Among them, the servo motor 212 is installed on the first fixed support 214 and is connected to the rotating shaft of the driving wheel 213. The first fixed support 214 is fixed on the chassis 2. The first universal wheel 211 and the driving wheel 213 both pass through the chassis 2. The balance wheel component 22 includes a second fixed support 221 installed on the top of the chassis 2. Two second universal wheels 222 are installed on the second fixed support 221. The second universal wheels 222 pass through the chassis 2 and are symmetrically designed with the first universal wheel 211.

[0027] Through the gear train structure design of the driving component 21 and the balance wheel component 22, it can better adapt to the ground. During movement, the universal wheel one 211 and the universal wheel two 222 are used to provide the stability and flexibility of movement, allowing the trolley to maintain good direction control when turning on uneven ground. The servo motor 212 is connected to the driving wheel 213. By precisely controlling the rotation speed and steering of the motor, precise movement and positioning of the trolley are achieved. The driving wheel 213 serves as the main power source of the trolley, responsible for driving the trolley forward, backward, and turning. The universal wheel one 211 and the driving wheel 213 are connected to a fixed support one 214, which can make more effective use of the traction force of the driving wheel 213. At the same time, the driving wheel 213 and the rear universal wheel one 211 share a fixed support one 214, meaning that their relative positions are more fixed, which is conducive to maintaining the stability of the vehicle during driving and reducing the risk of rollover caused by uneven road surfaces or turning. The universal wheel two 222 uses a separate fixed support two 221, which is conducive to achieving better steering controllability. As a steering wheel, the universal wheel two 222 needs to have higher flexibility and response speed. Using a separate fixed support two 221 can reduce the resistance of the universal wheel two 222 during the steering process and improve the accuracy and smoothness of steering.

[0028] The obstacle avoidance lidar 23 is installed in the direction of the transport end of the equipment rack 1, and the detection head of the obstacle avoidance lidar 23 passes through the notch at the lower end of one side of the equipment rack 1.

[0029] As described above, placing the core components of the obstacle avoidance lidar 23 on the top of the chassis 2 and inside the trolley, and only the detection head passes through the equipment rack 1, can well protect the core components from damage, and Figure 9 it can be seen that the detection head is located at the notch position of the equipment rack 1, so it is less likely to collide during the movement of the trolley, further improving the safety and stability of transportation.

[0030] A touch control screen 11 is installed on the top of one equipment rack 1, and an acrylic protection board is hinged on one side of the touch control screen 11. Docking optoelectronics 12 are installed on both sides of the two equipment racks 1

[0031] As described above, both the touch control screen 11 and the docking optoelectronics 12 are existing design means, which can well assist the trolley in moving or loading and unloading. For example, the trolley can be manually controlled through the touch screen 11 to start the servo motor 212 or control the output frequency, and the docking optoelectronics 12 can be used to react with the reflector at the loading and unloading position to turn off the servo motor 212, so as to accurately stop at the position.

[0032] Working principle: First, the trolley runs to the vicinity of the conveyor line. After verifying the docking accuracy between the trolley and the conveyor line through the docking photoelectric 12 on the trolley and the reflective plate at the corresponding position of the conveyor line, the trolley and the conveyor line complete the transportation docking task of the material box. After the trolley receives the material box, it will detect the signal of the roller control photoelectric 41. When the middle photoelectric is triggered, the roller conveyor line on the trolley slows down. When the third photoelectric is triggered, the roller conveyor line of the trolley stops, and then the trolley completes the docking task. After that, the trolley is driven to move by the drive assembly 21 and the balance wheel assembly 22. The obstacle avoidance laser radar 23 is installed on the trolley, which can effectively enable the trolley to detect obstacles, thereby preventing collisions. It should be noted that the linkage between the roller control photoelectric 41 and the electric roller 33 is a prior art and will not be elaborated here.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
