[0034] Exemplarily, please refer to Figure 1 as shown Figure 1The figure is a schematic structural diagram of the feeding device provided by the embodiment of the present application. The feeding device of the present application can be used for feeding materials. For example, it can be used for feeding silicon wafers in the production process of photovoltaic modules. Specifically, it can be used for feeding silicon wafers into a wet etching basket.

[0035] Referring to Figure 1 and Figure 2 As shown, the present application provides a feeding device, which includes a stock storage device 1, a feeding device 2, and a material transfer device 3. The stock storage device 1 is used for storing materials, the material transfer device 3 is used for transferring the materials stored in the stock storage device 1 to the feeding device 2, and the feeding device 2 is used for transporting silicon wafers. The stock storage device 1 includes a material box 11, a carrier plate 12, and an air knife 13. The material box 11 has an opening, the carrier plate 12 is arranged inside the material box 11, the carrier plate 12 is used for storing materials, and the air knife 13 is arranged on the material box 11. The air knife 13 is used for blowing air onto the materials placed on the carrier plate 12 to separate the stacked materials. The number of air knives 13 is multiple, and the multiple air knives 13 are respectively arranged on two opposite sides of the material box 11. The number of material boxes 11 is multiple, and the multiple material boxes 11 are arranged in an array. The number of feeding devices 2 is the same as the number of columns of the material boxes 11.

[0036] The above feeding device includes a stock storage device 1, a feeding device 2, and a material transfer device 3. The stock storage device 1 includes a material box 11, a carrier plate 12, and an air knife 13. When the material transfer device 3 transfers the materials from the carrier plate 12 inside the material box 11 to the feeding device 2, the air knife 13 blows air onto the materials placed on the carrier plate 12 to separate the stacked materials, which facilitates the material transfer device 3 to transfer individual materials and then feed them through the feeding device 2. At the same time, the air knife 13 and the material box 11 are integrated. The number of air knives 13 is multiple, and the multiple air knives 13 are respectively arranged on two opposite sides of the material box 11, directly forming an integrated stock storage device 1, which is convenient to use. Further, the number of material boxes 11 in the stock storage device 1 is multiple, and the multiple material boxes 11 are arranged in an array. The number of feeding devices 2 is the same as the number of columns of the material boxes 11, which facilitates feeding the materials in multiple columns of material boxes 11 through the feeding device 2 to match multiple columns of baskets. The feeding device of the present application can accurately feed single-piece materials and can match multiple columns of baskets at the same time, improving production efficiency.

[0037] By simultaneously blowing air onto the materials placed on the carrier plate 12 through multiple air knives 13 respectively arranged on two opposite sides of the material box 11, the separation effect of the stacked materials can be better. At the same time, the feeding device 2 grabs individual materials. Under the action of the multiple air knives 13 blowing air simultaneously, the rising of the materials is more stable.

[0038] Exemplarily, referring to Figure 2As shown, in one embodiment, four air knives 13 are respectively arranged on the left and right sides of the material box 11, with two on each of the left and right sides, and the two air knives 13 on the left side and the two air knives 13 on the right side are arranged corresponding to each other.

[0039] Multiple material boxes 11 are arranged in an array, which can improve the feeding efficiency. The transfer device 2 can transfer the materials on the uppermost layer of multiple material boxes 11 at one time, so as to meet the production requirements of multiple columns of flower baskets. At the same time, the number of feeding devices 2 is the same as the number of columns of the material boxes 11. Through the transfer device 2, the materials in each column of the material boxes 11 can be transferred to the same feeding device 2, and then the feeding device 2 feeds multiple materials, with relatively high efficiency.

[0040] In some embodiments, the number of the material boxes 11 is from 2×2 to 4×8. Optionally, the number of the material boxes 11 is 2×2, 2×4, 2×6, 2×8, 4×4, 4×6 or 4×8. Refer to Figure 1 and 2 As shown, in one embodiment, the number of the material boxes 11 is 2×4, that is, an array distribution of 2 columns and 4 rows, and the number of the feeding devices 2 is also 2.

[0041] In some embodiments, the transfer device 3 includes a material taking member 31, and the material taking member 31 is used for grasping and releasing the materials.

[0042] In some embodiments, the transfer device 3 includes an adjusting member 32. The adjusting member 32 is connected to the material taking member 31, and the adjusting member 32 is used for adjusting the force when the material taking member 31 grasps the materials.

[0043] In some embodiments, the material taking member 31 includes a suction cup, and the adjusting member 32 is used for adjusting the suction force of the suction cup on the materials.

[0044] When transferring wafers of different sizes, the suction force of the suction cup on the wafers can be adjusted by the adjusting member 32, so that the suction cup is suitable for wafers of different sizes, and the transfer effect is better.

[0045] In some embodiments, the number of the material taking members 31 is multiple, and the multiple material taking members 31 are arranged in an array, and the multiple material taking members 31 and the multiple material boxes 11 are in one-to-one correspondence.

[0046] It can be understood that one-to-one correspondence means that each material taking member 31 is used for transferring the materials in each material box 11. The multiple material taking members 31 are arranged in an array, and the multiple material taking members 31 and the multiple material boxes 11 are in one-to-one correspondence, and the feeding efficiency is relatively high.

[0047] Refer to Figure 3 and Figure 4As shown, in some of these embodiments, the stock storage device 1 further includes a lifting member 16. The lifting member 16 is disposed within the cartridge 11. The lifting member 16 is connected to the carrier plate 12, and the lifting member 16 is used to control the lifting of the carrier plate 12.

[0048] In some of these embodiments, the stock storage device 1 further includes a positioning member 14. The positioning member 14 is used to position the height of the material located on the carrier plate 12.

[0049] When feeding is not required, the carrier plate 12 can be controlled to descend by the lifting member 16 to store the material within the cartridge 11. When feeding the material is required, the carrier plate 12 can be controlled to ascend by the lifting member 16. At the same time, the height of the material on the carrier plate 12 is positioned by the positioning member 14, so that the material ascends to a suitable height for the picking member 31 to pick up the material. At the same time, after the material on the upper layer is taken away, the above steps can be repeated, and the material below can be made to ascend to a suitable height through the cooperation of the lifting member 16 and the positioning member 14.

[0050] In some of these embodiments, the positioning member 14 includes opposed light fibers respectively disposed on two opposite sides of the cartridge 11. When the opposed light rays are blocked by the material as it ascends, positioning of the material can be achieved.

[0051] Refer to Figure 5 As shown, in some of these embodiments, the air knife 13 includes a support member 131 and a blowing member 132. The support member 131 is disposed on the cartridge 11, and the blowing member 132 is disposed on the support member 131. The blowing member 132 has an air outlet 132a and an air inlet 132b. The air outlet 132a is horizontally disposed, and the height of the air outlet 132a in the vertical direction is the same as the height of the positioning member 14; the air inlet 132b is vertically downwardly disposed.

[0052] The air outlet 132a is horizontally disposed, and the height of the air outlet 132a in the vertical direction is the same as the height of the positioning member 14. When the material ascends to the height of the positioning member 14 through the positioning of the positioning member 14, it can just blow the uppermost layer of the material through the air outlet 132a of the blowing member 132 to separate it from the lower layer of the material, enabling more accurate transfer of individual materials. The vertically downward disposition of the air inlet 132b can save the overall space of the equipment.

[0053] In some of these embodiments, the cartridge 11 includes side plates 111 and a base 112. The side plates 111 are disposed on the surface of the base 112, and the side plates 111 surround the periphery of the carrier plate 12. The lifting member 16 is disposed on the base 112. The support member 131 is disposed on the surface of the base 112 located outside the side plates 111.

[0054] In some of these embodiments, the stock storage device 1 further includes a limiting member 15, and the limiting member 15 is disposed on the surface of the side plate 111 away from the base 112. When the carrier plate 12 rises to a height exceeding the opening of the material box 11, the limiting member 15 is located on the periphery of the carrier plate 12, and the limiting member 15 is used to limit the position of the material on the carrier plate 12.

[0055] When the lifting member 16 controls the carrier plate 12 to rise to a height exceeding the opening of the material box 11, it is more convenient to transfer the material. At this time, the limiting member 15 is located on the periphery of the carrier plate 12, and can limit and protect the material to prevent the material from sliding or falling.

[0056] In some of these embodiments, the limiting member 15 includes a plurality of limiting columns arranged at intervals, and the plurality of limiting columns surround the surface of the side plate 111 away from the base 112. The air knife 13 blows air on the material through the intervals between the limiting columns.

[0057] In some of these embodiments, the feeding device further includes a standby device 4, and the standby device 4 is provided with a parking position 41 for parking the transfer device 3.

[0058] When it is not necessary for the transfer device 3 to transfer materials or an error occurs in the production process, the transfer device 3 can be parked on the parking position 41, which is convenient for inspecting the equipment.

[0059] In some of these embodiments, the feeding device 2 includes a conveyor belt 21 and a driving member 22, and the driving member 22 is used to control the movement of the conveyor belt 21.

[0060] It is convenient to continuously load multiple silicon wafers through the conveyor belt 21, and the conveyor belt 21 is convenient to cooperate with the wet etching basket.

[0061] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0062] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims, and the description and drawings can be used to explain the content of the claims.
