[0037] An embodiment of the present application provides a feeding device for conveying materials such as silicon wafers. Figures 1 to 3 The feeding device of one embodiment includes a shelf 10, an AGV trolley 20, and a drain pipe 30. The shelf 10 is provided with a trough 111 for accommodating materials. The bottom wall of the trough 111 is provided with a drain port 112, which is provided with a valve 13. The AGV trolley 20 is used to transport the shelf 10. The drain pipe 30 is used to be installed in a drainage station. The drain pipe 30 includes a pipe body 31 and a push rod 32 provided in the drain pipe 30. The push rod 32 is used to push open the valve 13 of the shelf 10 entering the drainage station, so that the drain port 112 is connected to the pipe body 31.

[0038] The above-mentioned feeding device is provided by opening a drain port 112 on the bottom wall of the receiving groove 111 of the shelf 10, and setting a valve 13 at the drain port 112. At the same time, a drain pipe 30 is set on the drainage station, and a push rod 32 is set in the pipe body 31 of the drain pipe 30. In this way, when there is water accumulated in the shelf 10, the shelf 10 can be transported to the drainage station by the AGV trolley 20. After the shelf 10 enters the drainage station, the push rod 32 can push open the valve 13 so that the drain port 112 of the shelf 10 is connected with the pipe body 31. The accumulated water in the shelf 10 can pass through the drain port 112 and be discharged along the pipe body 31, realizing automatic drainage, avoiding the accumulation of water in the shelf 10, and thus preventing the materials in the shelf 10 from being corroded by the accumulated water. At the same time, compared with the traditional shelf 10 that requires workers to manually drain the water, the feeding device of the present application can realize automatic drainage of the shelf 10, reducing labor costs and improving production efficiency.

[0039] Referring to Figure 3 , in one embodiment, valve 13 is a one-way valve. Specifically, valve 13 includes a valve body (not labeled) and a valve core (not shown). The valve body defines a flow channel 131, and the valve core is movably disposed in the flow channel 131. The valve core has a closed position that blocks the flow channel 131 and an open position that allows the flow channel 131 to flow. The valve core can be maintained in the closed position under the action of the water pressure in the accommodating tank 111, and can be moved to the open position under the support of the push rod 32. Specifically, when water accumulates in the accommodating tank 111 of the rack 10 and the rack 10 has not entered the drainage position, the valve core can be maintained in the closed position under the action of the water pressure in the accommodating tank 111 to block the flow channel 131, thereby preventing the accumulated water from leaking from the flow channel 131 to areas outside the drainage position. When the AGV trolley 20 transports the shelf 10 to the drainage station, the push rod 32 extends into the flow channel and abuts against the valve core. The valve core can enter the open position under the support of the push rod 32. At this time, the flow channel 131 is opened, and the flow channel 131 connects the drain port 112 and the tube body 31, so that the accumulated water in the accommodating cavity is discharged.

[0040] Alternatively, in one embodiment, see Figure 2 The shelf 10 includes a box body 11 and a plurality of legs 12. A receiving groove 111 is provided on the box body 11. The legs 12 are spaced apart and support each other with the box body 11. A clearance 122 for the AGV trolley 20 to enter and exit is formed between two adjacent legs 12. For example, a leg 12 is provided at each of the four corners of the box body 11. A clearance 122 for the AGV trolley 20 to enter and exit is formed between two adjacent legs 12 on the same side, so that the AGV trolley 20 can enter the bottom of the box body 11. At this time, the AGV trolley 20 can transport the shelf 10 to the drainage station by carrying the box body 11.

[0041] Specifically. Figure 2 The AGV trolley 20 includes a body 21 and a lifting mechanism 22 provided on the body 21. The lifting mechanism 22 is used to support the shelf 10 and can drive the shelf 10 to rise or fall. When drainage is required, the AGV trolley 20 first enters the bottom of the box body 11 through the avoidance opening 122, and then the lifting mechanism 22 lifts the shelf 10 so that the legs 12 of the shelf 10 leave the ground. The AGV trolley 20 then transports the shelf 10 to the drainage station and aligns the top rod 32 in the drain pipe 30 with the outlet of the valve 13. The lifting mechanism 22 then lowers the shelf 10 so that the top rod 32 is inserted into the flow channel 131 of the valve 13 and lifts the valve core to the open position. At this time, the flow channel 131 is opened, and the collected flow can be discharged into the drain pipe 30 along the flow channel 131.

[0042] Optionally, in one embodiment, when the water level in the accommodating tank 111 reaches a certain height, the AGV trolley 20 automatically transports the shelf 10 to the drainage station for drainage. Figure 2 , a liquid level meter 114 connected to the receiving tank 111 can be provided on the box body 11. The liquid level meter 114 is used to detect the liquid level height in the receiving tank 111. When the liquid level reaches a preset height, the liquid level meter 114 sends a drainage signal. After receiving the signal, the AGV trolley 20 automatically transports the shelf 10 to the drainage station for drainage. In other embodiments, the liquid level height in the receiving tank 111 can also be detected by a laser sensor, which is not limited here. Or in another embodiment, the AGV trolley 20 can also be set by the program to automatically transport the shelf 10 to the drainage station for drainage once after continuously transporting the shelf 10 for a certain number of times, thereby eliminating the process of detecting the liquid level height in the receiving tank 111.

[0043] Continue to see Figure 2 Optionally, in one embodiment, one end of the support leg 12 away from the box body 11 is connected to a universal wheel 121. In this way, it is convenient to move the shelf 10 and save manpower.

[0044] See also Figure 4 Optionally, in one embodiment, two opposing sidewalls of the receiving slot 111 are each provided with a plurality of dividers 116. The dividers 116 on the two sidewalls are arranged one after another to divide the receiving slot 111 into a plurality of placement positions 117, each of which is configured to accommodate a single item. The dividers 116 effectively position the items, allowing them to be more regularly placed in the receiving slot 111, facilitating subsequent retrieval. This also prevents collisions and damage between items during transport of the shelf 10.

[0045] See also Figure 4 Optionally, in one embodiment, there are at least two drain ports 112, each of which is spaced apart and arranged on the bottom wall of the accommodating tank 111, and all of the drain ports 112 are connected to the valve 13. By draining water through multiple drain ports 112 simultaneously, the drainage speed can be accelerated, further improving production efficiency.

[0046] Specifically, there are two drain outlets 112: a first drain outlet 1121 and a second drain outlet 1122. The first drain outlet 1121 has a larger diameter than the second drain outlet 1122, and a filter 115 is installed in the first drain outlet 1121. The larger diameter of the first drain outlet 1121 expedites drainage, and the filter 115 prevents large impurities from entering the flow passage 131 of the valve 13 through the first drain outlet 1121 and potentially blocking the valve 13. The smaller diameter of the second drain outlet 1122 allows small impurities to be discharged from the accommodating tank 111 along with the accumulated water, ensuring a clean and tidy interior.

[0047] See also Figure 5 as well as Figure 6 In one embodiment, the drain pipe 30 further includes a connecting rib 33, one end of which is connected to the inner wall of the pipe body 31, and the other end of which is connected to the top rod 32, thereby stably fixing the top rod 32 in the pipe body 31. Furthermore, there are multiple connecting ribs 33, which are arranged at intervals along the circumference of the top rod 32. A gap is provided between adjacent connecting ribs 33 for accumulated water to flow out, thereby further improving the stability of the top rod 32.

[0048] On the other hand, the present application further provides a slicing system. The slicing system of one embodiment includes a feeding device according to any one of the above embodiments, and the feeding device is used to transport silicon wafers.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
