[0044] 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.

[0045] During the processing of battery cells, a material box is required to store the wafers (such as silicon wafers or battery cells). Existing material boxes usually include a bottom plate and a side plate arranged on the bottom plate. The bottom plate and the side plate enclose a chamber for storing silicon wafers, and the silicon wafers are fed into the material box from the feeding end of the chamber. However, in actual production, when the wafer enters the chamber at a high speed, the material box with this structure is easily damaged due to the hard contact between the wafer and the contacting side plate.

[0046] Therefore, this application proposes a sheet material receiving box, please refer to Figures 1 to 3 As shown, the sheet material receiving box proposed in the embodiment of the present application includes a carrier 10, a first stopper 20 and a second stopper 30, wherein: an inclined surface 11 for supporting a sheet 40 is formed on the carrier 10, the inclined surface 11 includes a feed end and a diagonal end, the inclined surface 11 is arranged downwardly inclined from the feed end to the diagonal end, and the two sides of the diagonal end are a first side edge 12 and a second side edge 13 perpendicular to each other; the first stopper 20 includes a first support member 21 and a first buffer pad 22, the first support member 21 is installed at the first side edge 12, and the first The buffer pad 22 is installed on the first support member 21 according to a preset tightness so that the first buffer pad 22 is not fully tensioned on the first support member 21, and the second limit member 30 is arranged at the second side edge 13; the first limit member 20 and the second limit member 30 are configured to block two adjacent sides of the feeding sheet 40. When the sheet 40 is fed into the material box from the feeding end, the sheet 40 first contacts the first buffer pad 22, and then slides along the inclined surface 11 until the two sides of the sheet 40 respectively abut against the first buffer pad 22 and the second limit member 30.

[0047] It can be seen that the sheet material receiving box proposed in the present application, by setting an inclined surface 11 on the supporting member 10, and setting a first limit member 20 and a second limit member 30 on the inclined surface 11, can make the sheet 40 fed into the material box first contact the first buffer pad 22 and then slide along the inclined surface 11 toward the second limit member 30, thereby realizing automatic alignment of the sheet 40, thereby ensuring that the sheets 40 in the material box are neatly stacked; at the same time, by installing the first buffer pad 22 on the first support member 21 without being fully tensioned, the sheet 40 fed into the material box at high speed has a good buffering effect when contacting the first buffer pad 22, thereby greatly reducing the probability of damage to the sheet 40 and ensuring the processing quality of the sheet 40.

[0048] See also Figure 1 and Figure 3 As shown, as an embodiment, the first support member 21 is frame-shaped, and the first buffer pad 22 is detachably covered on the frame of the first support member 21. The area of ​​the first buffer pad 22 opposite to the area within the frame of the first support member 21 is an untensioned area. When the sheet 40 is fed into the material box from the feeding end, the sheet 40 first contacts the untensioned area of ​​the first buffer pad 22.

[0049] It can be seen that by setting the first support member 21 in a frame shape and setting the area within the frame of the first support member 21 opposite to the untensioned area of ​​the first buffer pad 22, there is no hard support behind the untensioned area of ​​the first buffer pad 22, thereby ensuring the buffering effect of the untensioned area.

[0050] As an embodiment, the first support member 21 is a rectangular frame formed by connecting the first side slat 210, the lower slat 211, the second side slat, and the upper slat 212 in sequence. The plane where the rectangular frame is located is arranged perpendicular to the inclined surface 11. The lower slat 211 is detachably installed at the first side edge 12 at the diagonal end, and the length direction of the lower slat 211 extends along the length direction of the first side edge 12 at the diagonal end. The untensioned area of ​​the first buffer pad 22 covers the front side of the rectangular frame, and the front side is a side of the rectangular frame facing the feeding sheet body 40. The two ends of the first buffer pad 22 extend from the front side of the rectangular frame around the first side slat 210 and the second side slat to the back side of the rectangular frame, and the two ends of the first buffer pad 22 are respectively fixed to the first side slat 210 and the second side slat at the back side of the rectangular frame by locking members.

[0051] Specifically, the locking members are multiple screws, and the first side strip 210 and the second side strip are both provided with multiple threaded holes. Multiple through holes 220 are opened on both ends of the first buffer pad 22, and each through hole 220 corresponds to a threaded hole. Each screw passes through a through hole 220 on the first buffer pad 22 and is locked in the corresponding threaded hole to fix the two ends of the first buffer pad 22 on the first side strip 210 and the second side strip 211 respectively.

[0052] It can be seen that by setting the first support member 21 as a rectangular frame formed by connecting the first side strip 210, the lower strip 211, the second side strip, and the upper strip 212 in sequence, a first support member 21 with a simple structure and stable and reliable support is provided; by covering the untensioned area of ​​the first buffer pad 22 on the front side of the rectangular frame, hard contact between the sheet body 40 and the contacting first buffer pad 22 is avoided; the two ends of the first buffer pad 22 are respectively fixed to the first side strip 210 and the second side strip by a locking member, providing an installation method for the first buffer pad 22 with a simple structure and easy replacement.

[0053] As an embodiment, the second limiting member 30 includes a second support member 31 and a second buffer pad 32. The second support member 31 is installed at the second side edge 13. The second buffer pad 32 is detachably installed on the second support member 31. The second buffer pad 32 is configured to contact the side of the sheet 40 falling into the sheet receiving box.

[0054] Specifically, the second support member 31 has the same structure as the first support member 21, which will not be described again here; it should be noted that: a plurality of strip holes are opened at the bottom of the frame of the second support member 31, and the length direction of the strip holes is parallel to the length direction of the second side 13. The second support member 31 is fixed to the second side 13 by screws at the strip holes. The arrangement of the strip holes makes the installation position of the second support member 31 along the length direction of the second side 13 adjustable to adapt to sheets 40 of different sizes, and has good compatibility.

[0055] It can be seen that through the cooperation of the second support member 31 and the second buffer pad 32, the limitation of one of the side edges of the sheet body 40 is achieved, and the second buffer pad 32 has a buffering effect when in contact with the sheet body 40; at the same time, by detachably installing the second buffer pad 32 on the second support member 31, the replacement of the second buffer pad 32 is facilitated.

[0056] As an embodiment, the second buffer pad 32 is tensionedly mounted on the second support member 31 , or the second buffer pad 32 is mounted on the second support member 31 at a preset tightness, so that the second buffer pad 32 is not fully tensioned on the second support member 31 .

[0057] Specifically, the second buffer pad 32 is fixed to the two side strips of the second support member 32 by screws at both ends of the second buffer pad 32 in a tensioned state.

[0058] Specifically, the installation method of the second buffer pad 32 installed on the second support member 31 without being fully tensioned is the same as the installation method of the first buffer pad 22, which will not be repeated here.

[0059] It can be seen that by tensioning the second buffer pad 32 on the second support member 31, reliable and accurate limiting of one of the side edges of the sheet body is achieved; by installing the second buffer pad 32 on the second support member 31 without being fully tensioned, the sheet body 40 also has a good buffering effect when contacting the second buffer pad 32, thereby reducing the probability of damage to the sheet body 40 and further protecting the sheet body.

[0060] See also Figure 1 and Figure 2 As shown, as an embodiment, the sheet material receiving box also includes a base 50 and a connecting member 60, the first end of the connecting member 60 is mounted on the base 50, the second end of the connecting member 60 is formed with a mounting slope 61, the supporting member 10 is fixedly mounted on the mounting slope 61, and the mounting slope 61 supports the supporting member 10 so that the upper surface of the supporting member 10 is inclined to the inclined surface 11.

[0061] Specifically, the base 50 is a flat structure, the connecting member 60 is a columnar structure, the connecting member 60 is vertically fixed in the middle position of the upper plate surface of the base 50, the upper end surface of the connecting member 60 is an inclined mounting slope 61, and the supporting member 10 is an inclined plate. In order to further improve the buffering effect and protect the sheet body 40, a pad 110 can be attached to the supporting member 10. The pad 110 is made of epoxy resin. After the pad 110 is worn, only the pad 110 needs to be replaced, which is beneficial to reduce the use cost of the material box.

[0062] It can be seen that through the cooperation of the base 50, the connecting member 60 and the supporting member 10, an inclined surface 11 for supporting the sheet body 40 is formed on the upper surface of the supporting member 10. At the same time, by replacing the connecting member 60 with the mounting inclined surface 61 with different inclinations, the angle of the inclined surface 11 can be adjusted.

[0063] As an implementation manner, a plurality of picking portions 51 are provided on the base 50 to facilitate the material box transporting mechanism to transport the material box.

[0064] Specifically, the base 50 is provided with four picking parts 51 located at the periphery of the carrier 10, each picking part 51 includes a mounting block 510 and a clamping column 511, the first end of the mounting block 510 is fixed to the base 50, and the clamping column 511 is fixed to the second end of the mounting block 510 and extends outward relative to the carrier 10. Four hooks are provided on the material box conveying mechanism, and when conveying the material box, each hook corresponds to a clamping column 511, and the four hooks of the material box conveying mechanism hook the corresponding clamping column 511 to obtain the material box.

[0065] It can be seen that the cooperation between the picking portion 51 and the material box conveying mechanism facilitates the material box conveying mechanism to obtain and convey the material box, thereby realizing the automatic circulation of the material box.

[0066] As an implementation manner, an electronic tag or a graphic code for identifying the sheet material receiving box is disposed on the base 50 .

[0067] Specifically, the graphic code may be a two-dimensional code or a bar code, etc. A mounting groove 52 is provided on the bottom surface of the base 50 , and the electronic tag or the graphic code is provided in the mounting groove 52 .

[0068] It can be seen that by setting the electronic tag and the graphic code on the base 50 so as to be read by the code reader, identification of different material boxes is achieved.

[0069] As an implementation manner, a plurality of positioning members 53 are disposed on the base 50 , and the positioning members 53 cooperate with external guide members to realize the positioning of the placement position of the sheet material receiving box.

[0070] Specifically, the positioning member 53 includes at least two positioning sleeves installed on the base 50 at intervals, and positioning columns are correspondingly arranged at the placement position of the sheet material receiving box.

[0071] It can be seen that, through the cooperation of the positioning sleeve and the positioning column, the base 50 can be positioned at the placement position of the material box, thereby achieving the positioning of the material box.

[0072] The sheet material receiving box provided in the embodiment of the present application has the following advantages:

[0073] 1) Automatic alignment of the sheets falling onto the inclined surface is achieved, thereby ensuring that the sheets in the material box are neatly stacked.

[0074] 2) The first buffer pad has a good buffering effect. When the sheet fed into the material box at high speed contacts the first buffer pad, it is buffered by the first buffer pad, which greatly reduces the probability of sheet damage and ensures the processing quality of the sheet.

[0075] 3) The overall structure of the first limiter and the second limiter is simple, which facilitates the replacement of the buffer pad.

[0076] 4) A picking portion is provided on the base to facilitate the material box transporting mechanism to pick up the material box.

[0077] 5) An electronic tag or graphic code is provided on the base to identify different material boxes.

[0078] See also Figure 4 As shown, the present application also provides a sheet receiving device. The sheet receiving device provided in the embodiment of the present application includes a sheet conveying mechanism 70 and the above-mentioned sheet receiving box; wherein: the sheet receiving box is arranged at the discharge end of the sheet conveying mechanism 70, and the sheet conveying mechanism 70 is configured to convey the sheet 40 toward the discharge end; the first limit member 20 is arranged facing the discharge end of the sheet conveying mechanism 70, and the sheet receiving box is configured to receive and store the sheets conveyed by the sheet conveying mechanism 70.

[0079] Specifically, the sheet conveying mechanism 70 adopts a narrow belt conveying line.

[0080] It can be seen that the automatic collection of the sheet 40 is achieved through the cooperation of the sheet conveying mechanism 70 and the sheet receiving box; at the same time, the sheet 40 fed into the sheet receiving box at high speed has a good buffering effect when it contacts the first buffer pad 22, which greatly reduces the probability of damage to the sheet 40 and ensures the processing quality of the sheet.

[0081] As an embodiment, the first side edge 12 at the diagonal end is offset by a predetermined angle ( Figure 3 The predetermined angle (A) is set such that the first horizontal direction is perpendicular to the conveying direction of the sheet conveying mechanism 70, and the predetermined angle is an acute angle, so that when the sheet 40 enters the material box from the feeding end, one of the corners of the sheet 40 away from the second limit member 30 contacts the first buffer pad 22 first.

[0082] It can be seen that by offsetting the first side edge 12 at the diagonal end toward the sheet conveying mechanism 70 by a predetermined angle, it is achieved that when the sheet 40 enters the material box, Figure 4 , one of the edges of the sheet 40 away from the second stopper 30 first contacts the first buffer pad 22, and then the sheet 40 moves along Figure 4 The sheet 40 rotates in the direction of the arrow and slides along the inclined surface 11 , so that the two side edges of the sheet 40 are closely attached to the first buffer pad 22 and the second stopper 30 , respectively, to ensure that the edges of the stacked sheets 40 are aligned.

[0083] As an implementation manner, the predetermined angle ranges from 0° to 9°.

[0084] Specifically, the predetermined angle can be any angle of 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, etc. The preferred angle range is 3° to 6°. It should be noted that when the predetermined angle is 0°, the front side of the sheet 40 first contacts the first buffer pad 22, and then the sheet 40 slides along the inclined surface 11, and the two side edges of the sheet 40 can also be closely attached to the first buffer pad 22 and the second stopper 30, respectively, to ensure that the edges of the superimposed sheets 40 are aligned.

[0085] It can be seen that by setting the value range of the predetermined angle to 0° to 9°, it can be ensured that both side edges of the sheet 40 can be in contact with the first buffer pad 22 and the second stopper 30, so that the sheet 40 can be stacked neatly.

[0086] The above embodiments are only to illustrate the basic principles and characteristics of the present application. The present application is not limited by the above examples.
