[0029] Please see Figures 1 to 5 This application exemplarily provides a trolley for conveying material trays, comprising:

[0030] Car body 1;

[0031] Frame 2 is mounted on the trolley body 1.

[0032] A conveying assembly, mounted on frame 2, is used to carry or transport material trays;

[0033] A movable component is located at the bottom of the vehicle body 1 and is used to move the vehicle body 1.

[0034] In the trolley for conveying material trays provided in this application, the trolley's moving component can move to the location of the material tray, the conveying component transmits and carries the material tray, the trolley can transport stacked material trays, and move them to a designated location via the moving component, and then send the material trays out via the conveying component to transport the conveying component to the designated location, thus completing the material tray handling. No manual handling is required, which can not only reduce labor input costs, but also improve handling efficiency and production efficiency.

[0035] In this embodiment, the trolley body 1 is provided with a support plate 9 and a support seat 10 connected to each other. The top of the support plate 9 is connected to the bottom of the frame 2, and the bottom of the support seat 10 is connected to the trolley body 1. The support plate 9 and the support seat 10 support the frame 2, thereby enhancing the stability of the trolley during the material handling and movement process.

[0036] In some embodiments, the conveying assembly includes conveyor belts 3 arranged opposite each other on the frame 2, with intervals between the conveyor belts 3, and conveying platforms 4 on the conveyor belts 3. The conveyor belts 3 are used to feed trays into or out of the conveying platforms 4. Specifically, there are two or more conveyor belts 3, which are arranged opposite each other on the frame 2. The two oppositely arranged conveyor belts 3 form one layer of conveying platforms 4. In this embodiment, there are four conveyor belts 3, which form conveying platforms 4 in pairs, so that there are two layers of conveying platforms 4 on the frame 2, which can increase the number of trays that the machine trolley can handle.

[0037] In the above embodiment, limiting plates 5 for limiting the material tray are also provided on both sides of the conveyor belt 3. The limiting plate 5 has an inclined structure 6 on the side near the beginning of the conveyor belt 3. The inclined structure 6 forms an outwardly expanding guide part at the beginning of the conveyor belt 3. Specifically, when the conveyor belt 3 transports the material tray, the limiting plate 5 limits the material tray to ensure that the material tray can be stably supported on the conveying platform 4. When the conveyor belt 3 sends the material tray into the conveying platform 4, the inclined structure 6 forms a guide part to guide the material tray to ensure that the transmission direction of the material tray will not deviate and to ensure that the material tray can be stably sent into the conveying platform 4. A baffle 27 is provided at the end of the conveyor belt 3. The material tray is sent into the conveying platform 4 through the conveyor belt 3 and the baffle 27 keeps the material tray on the conveying platform 4.

[0038] In this embodiment, the trolley for conveying the material tray also includes a drive assembly disposed between the conveyor belts 3. The drive assembly includes a first motor 21, a drive block 23, a lead screw 22, and a guide rail 24. The first motor 21 is connected to the lead screw 22. The drive block 23 is sleeved on the lead screw 22. The lead screw 22 is disposed vertically on the frame 2. The guide rail 24 is disposed parallel to the lead screw 22. A mounting plate 25 is disposed on the side of the conveyor belt 3 near the lead screw 22. All mounting plates 25 are connected to the drive block 23. The mounting plates 25 are connected to each other by a connecting plate 26. 6 is mounted on guide rail 24. The first motor 21 drives the lead screw 22 to rotate. The drive block 23 moves vertically on the lead screw 22 to drive the conveyor belt 3 to move vertically. Specifically, the trolley can dock with the feeding line of the storage tray. The horizontal height of the conveyor belt 3 is adjusted by the drive component so that the height of the conveyor belt 3 is level with that of the feeding line. The feeding line and the conveyor belt 3 work together to transfer the tray to the conveying platform 4. Similarly, the trolley can also move the tray to the feeding line and transfer the tray on the conveying platform 4 to the feeding line for storage.

[0039] In the above embodiment, the moving component includes a drive wheel 7, a second motor 18, a steering wheel 11, and an auxiliary wheel 12. The drive wheel 7 is disposed opposite to each other on the middle of the two sides of the trolley body 1. The drive wheel 7 is connected to the second motor 18. The second motor 18 drives the wheel 7 to rotate so as to move the trolley body 1. The steering wheel 11 and the auxiliary wheel 12 are disposed opposite to each other at the bottom of the trolley body 1. The steering wheel 11 is connected to the drive wheel 7 and is used to change the direction of movement of the trolley body 1. Specifically, the steering wheel 11 on the same side is connected to the drive wheel 7 through a connector 16, and the auxiliary wheels 12 are connected to each other through a connector 16. The connector 16 is fixed inside the trolley body 1 through a connecting seat 17. The steering wheel 11 and the auxiliary wheel 12 are arranged in an array at the bottom of the trolley body 1. The auxiliary wheel 12 cooperates with the steering wheel 11 to ensure the balance of the trolley during movement.

[0040] In some embodiments, the trolley for conveying the material tray also includes a lidar 13 for detecting obstacles. Specifically, there is a gap between the support plate 9 and the trolley body 1, and the lidar 13 is disposed on both sides of the trolley body 1. The lidar 13 is at least partially exposed in the gap. The lidar 13 emits detection lasers from the gap, thereby enabling the detection of obstacles on the path during the movement of the trolley, so as to ensure that the trolley is not obstructed during its movement.

[0041] In this embodiment, the trolley for transporting pallets also includes a control center 19 for receiving task instructions and map information. The control center 19 is located inside the trolley body 1. Specifically, the map information can be generated by the operator scanning the warehouse terrain. The control center 19 receives the map information and sends a task instruction to the trolley when pallets need to be transported. The control center 19 receives the task instruction and generates the movement path of the trolley according to the map information, thereby realizing the task scheduling of the trolley.

[0042] In the above embodiment, a collision protection strip 8 is provided circumferentially at the bottom of the trolley body 1 to protect the trolley body 1. The collision protection strip 8 protects the trolley body 1 and ensures that the trolley body 1 will not be damaged by collision during the movement of the robot trolley.

[0043] It is worth noting that a warning light strip 14 is provided on the circumferential side of the trolley body 1. During the movement of the trolley, the warning light strip 14 is constantly lit to remind the operator not to enter the movement area of ​​the trolley and to ensure the normal operation of the trolley.
