DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] like Figure 1 to Figure 3As shown, the present application is a material receiving device 1 for loading sheet materials such as silicon wafers or battery wafers.

[0037] The material receiving device 1 includes a base 10 and at least one material receiving unit 20. The illustrated embodiment includes two material receiving units 20. The base 10 is in the shape of a horizontal plate.

[0038] Each material receiving unit 20 includes a rotating assembly 21 , a lifting mechanism 22 , a supporting member 23 and a material box 24 .

[0039] The material box 24 includes a bottom plate 241, a first enclosure 242 and a second enclosure 243; the bottom plate 241 includes a feed end 244 and a diagonal end 245 opposite to the feed end 244; the diagonal end 245 includes a first side 246 and a second side 247 perpendicular to each other, the first enclosure 242 is located at the first side 246, and the second enclosure 243 is located at the second side 247, the bottom plate 241, the first enclosure 242 and the second enclosure 243 enclose a chamber for accommodating a sheet, and the first enclosure 242 and the second enclosure 243 are configured to block two adjacent sides of the sheet;

[0040] The feeding end 244 of the bottom plate 241 is rotatably mounted above the base 10 via the rotating assembly 21;

[0041] The support member 23 is mounted on the base 10 and is located below the diagonal end 245 of the bottom plate 241. The support member 23 is configured to support the diagonal end 245 of the bottom plate 241. When the diagonal end 245 of the bottom plate 241 is placed on the support member 23, the bottom plate 241 is tilted downward from the feed end 244 to the diagonal end 245.

[0042] The lifting mechanism 22 is located below the diagonal end 245 of the bottom plate 241 , and is configured to lift the material box 24 to rotate its bottom plate 241 to a horizontal position; the lifting mechanism 22 is also configured to lower the material box 24 so that the diagonal end 245 of the bottom plate 241 rests on the support 23 .

[0043] The present application uses the lifting mechanism 22 to support the material box 24 so that it rotates around the feeding end 244, so that the material box 24 can be in two states: tilted and horizontal. When the material box 24 is tilted, it is in the material receiving state. Because the material box 24 is tilted, the sheets will slide down along the inclined surface due to gravity after entering the material box 24, and abut against the first and second enclosures 242 and 243 of the material box 24, so that the sheets are automatically aligned; when the material box 24 is full of materials, it is adjusted to a horizontal state, so that the robot can take out the whole stack of sheets in the material box 24.

[0044] Optionally, the rotating assembly 21 includes a mounting block 211, a rotating shaft 212, a bearing and a connecting block 213, the rotating shaft 212 is mounted on the connecting block 213, the connecting block 213 is fixed to the bottom surface of the feed end 244 of the base plate 241, one end of the rotating shaft 212 is mounted on the mounting block 211 through a bearing, and the mounting block 211 is directly fixed on the base 10, or is mounted on the base 10 through a support 214.

[0045] The rotating assembly 21 adopts a structure in which a rotating shaft 212 cooperates with a bearing, and rotates flexibly.

[0046] Optionally, the lifting mechanism 22 uses a cylinder, the cylinder body of the cylinder is arranged below the base 10, and a through hole 11 is provided on the bottom plate 241 for the piston rod of the cylinder to extend out. The piston rod is configured to be able to extend out and abut the bottom plate 241, or retract to move away from the bottom plate 241.

[0047] The cylinder body of the cylinder is arranged below the base 10, that is, the cylinder body of the cylinder and the base 10 are not fixedly connected. During the production process, when the material box 24 needs to be transferred, the base 10 only needs to be transferred manually or by a robot. When the base 10 is transferred, the cylinder will not be moved together because the cylinder is connected to a pipeline, which can avoid the movement of the pipeline. In addition, the space below the base 10 can be fully utilized without interfering with the transfer of the base 10.

[0048] Optionally, threads are processed on the support member 23 , and the support member 23 is connected to the base 10 via threads, and the height of the support member 23 can be adjusted by screwing the support member 23 .

[0049] The support member 23 is connected by threads, and the height of the support member 23 can be conveniently adjusted by screwing the threads, thereby changing the tilt angle of the material box 24.

[0050] Optionally, the support member 23 is a screw or a bolt, and the head of the screw or the bolt faces upward, so that the diagonal end 245 of the material box 24 rests on the head of the screw or the bolt. When the tilt angle of the material box 24 needs to be adjusted, the piston rod of the cylinder can be controlled to extend to lift the material box 24, so that the diagonal end 245 of the material box 24 is away from the support member 23, and then the support member 23 is manually or with a tool to adjust the support member 23 to a suitable height, and then the piston rod of the cylinder is controlled to retract, and the diagonal end 245 of the material box 24 is lowered until the diagonal end 245 rests on the head of the screw or the bolt, that is, the tilt angle adjustment of the material box 24 is completed, so as to adjust the speed at which the sheet body slides down in the material box 24 to meet different user needs.

[0051] The support member 23 directly adopts standard screws or bolts, which can reduce the manufacturing cost.

[0052] Optionally, a notch 248 is provided at the feeding end 244 of the bottom plate 241 of the material box 24 .

[0053] A notch 248 is provided on the bottom plate 241 of the material box 24 , and the supported sheet is exposed at the notch 248 , so that the sheet can be clamped from the notch 248 when discharging the material.

[0054] In one embodiment, optionally, the material receiving device 1 includes two material receiving units 20, the two material receiving units 20 are symmetrically arranged, and the bottom plates 241 of the two material receiving units 20 are located between the first enclosure members 242 of the two material receiving units 20. Optionally, the rotating components 21 of the two material receiving units 20 are both mounted on the support 214, and the support 214 is mounted on the base 10.

[0055] By configuring two receiving units 20, the receiving efficiency is improved. The material boxes 24 in the two receiving units 20 can receive materials at the same time, or one of the material boxes 24 can receive materials first, and when the material box 24 is full, the other material box 24 can receive materials. When receiving materials, the sheet is released to the feeding end 244 of the material box 24, and the sheet slides from the feeding end 244 along the inclined surface of the bottom plate 241 toward the diagonal end 245. In addition, the two material boxes 24 can also receive materials by category.

[0056] Optionally, a plurality of clamping posts 12 for grabbing are installed on the base 10. The clamping posts 12 can be installed on the upper surface of the base 10 through a block. The embodiment shown in the figure includes four clamping posts 12, which are fixed on the base 10, two of which are fixed on one side edge of the base 10, and the other two are fixed on the other side edge of the base 10. The four clamping posts 12 are distributed at the four vertices of the quadrilateral, and the two material boxes 24 are arranged between the clamping posts 12 on both sides.

[0057] A clamping column 12 is provided on the base 10 , and the base 10 can be lifted by grasping the clamping column 12 by hand, or by hooking the clamping column 12 by a robot arm, so that the base 10 is easily transported.

[0058] According to the structure of the enclosure, the material box 24 has the following two embodiments.

[0059] The first material box 24 has a first enclosure 242 and a second enclosure 243 that are both strip-shaped, and the first enclosure 242 and the second enclosure 243 are perpendicular to the bottom plate 241. The inner side walls of the first enclosure 242 and the second enclosure 243 are provided with a buffer material. The first enclosure 242 and the second enclosure 243 are connected to form an L-shaped plate.

[0060] By configuring the buffer material, the sheet carried by the material box 24 can be prevented from directly hitting the first enclosure 242 and the second enclosure 243, thereby protecting the first enclosure 242, the second enclosure 243 and the sheet.

[0061] Optionally, in order to facilitate the robot arm to grab the sheets in the material box 24, some avoidance openings can be appropriately opened on the first enclosure 242 or the second enclosure 243.

[0062] The second material box 24, its first enclosure 242 includes more than two first baffles, all of which are arranged at intervals along the length direction of the first side 246, and the second enclosure 243 includes more than two second baffles, all of which are arranged at intervals along the length direction of the second side 247, and the length directions of the first baffles and the second baffles are both perpendicular to the plate surface of the bottom plate 241.

[0063] The first baffles and the second baffles are arranged at intervals, and the intervals in the middle can be used for exhaust. When stacking sheets in the material box 24, there is air between adjacent sheets, and the air can be discharged from the first baffles and the second baffles in time to avoid affecting the close stacking of sheets due to the presence of air, which can further ensure that the sheets are stacked neatly. In addition, it is also convenient for the robot to clamp the sheets from the gap between the first baffles or the second baffles.

[0064] The present application is described in sufficient detail above with certain particularity. It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application.
