In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] It should be noted that in the description of the present utility model, the terms "connection" and "installation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or connected through an intermediate medium; it can be a mechanical connection, or an electrical connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] In view of the technical problem in the prior art that the battery wafers are randomly stacked in the cassette, the utility model provides a battery wafer cassette. Referring to Figures 1 to 3 , the battery wafer cassette includes a bottom plate 1 and four side plates 2. The four side plates 2 are connected end to end in sequence, and their lower ends are all connected to the bottom plate 1. The bottom plate 1 and the four side plates 2 enclose a receiving cavity for placing battery wafers; an angle is formed between any two adjacent side plates 2. The bottom surface of the receiving cavity is inclined relative to the horizontal plane, and the lowest point of the bottom surface of the receiving cavity is located at one of the angles.

[0033] Referring to Figure 3 , the dotted line in the drawing represents the battery wafer; with the above battery wafer cassette, when the battery wafers are placed in the receiving cavity of the cassette, the battery wafers will slide under the action of gravity to the lowest point of the bottom surface of the receiving cavity, so that the battery wafers are neatly stacked at the angle where the lowest point of the bottom surface is located; the two side plates 2 forming the angle are respectively in contact with two adjacent sides of each battery wafer, so as to be able to regularize each battery wafer and further improve the neatness of the battery wafers. Since the battery wafers are neatly stacked in the cassette, it is beneficial for subsequent packaging of the battery wafers, and a robotic arm can also be used to take out the battery wafers from the cassette, improving the automation degree and production efficiency of the production line.

[0034] In this embodiment, the highest point of the bottom surface of the receiving cavity is located at an angle opposite to the angle where the lowest point is located.

[0035] Continuing to refer to Figure 1 and Figure 2 , a plurality of notches 5 are provided on the periphery of the receiving cavity. The provision of the notches 5 is used, on the one hand, for the gripper on the robotic arm to extend into the receiving cavity to pick up the battery wafers, realizing the automatic picking and placing of the battery wafers; on the other hand, air can be blown into the receiving cavity from the notches 5, so as to disperse the multiple battery wafers in the receiving cavity, enabling each battery wafer to smoothly slide down to the angle where the lowest point of the bottom surface is located, further improving the neatness of the battery wafers. In addition, the provision of the notches 5 can also reduce the weight of the cassette, facilitating the handling of the cassette.

[0036] Furthermore, a protective pad 3 is laid on the bottom surface and / or the side surface of the receiving cavity. In this embodiment, a protective pad 3 with a certain elasticity and a smooth surface is laid on the bottom surface and each side surface of the receiving cavity. In the above structure, the protective pad 3 can buffer the impact force between the battery wafer and the cassette when the battery wafer falls, avoiding damage to the battery wafer; in addition, the protective pad 3 is relatively smooth, which is beneficial for the battery wafer to slide down.

[0037] Continuing to refer to Figure 1 , in order to improve the automation degree of the production line, a slot 21 for the gripper 300 on the robotic arm to insert is provided on each side plate 2. Combining Figure 4The slot 21 is used for the clamping claw 300 to be inserted, thereby achieving the purpose of automatically transporting the material box and improving the degree of automation of the production line.

[0038] Reference Figure 5 A plurality of weight-reducing grooves distributed in a grid pattern are arranged on the outer side of the bottom plate 1 and / or the side plate 2. The above arrangement can reduce the weight of the material box without affecting the structural strength of the material box, so as to facilitate the handling of the material box.

[0039] Reference Figure 5 and Figure 6 The battery cell material box also includes a positioning structure 4 embedded in the bottom of the bottom plate 1, and the positioning structure 4 is used to align and connect with the positioning block 200 on the material box placement table 100. In this embodiment, the number of the positioning structures 4 is multiple (specifically four) and they are evenly distributed around the center of the material box to perform multi-point positioning on the battery cell material box and improve the positioning accuracy of the material box.

[0040] By using the above-mentioned battery cell material box, after the battery cell material box is placed on the material box placement table 100, the positioning structure 4 and the positioning block 200 can be connected in position, so that the battery cell material box can be accurately placed in the set area and the battery cell material box is not easy to shake, so that the robot arm can smoothly grab the material box, or take out the battery cells in the material box, or smoothly put the battery cells into the material box, further improving the degree of automation of the production line, while reducing the error rate of the robot arm during work.

[0041] Reference Figure 7 The positioning structure 4 includes a guide block 41, and a tapered hole 411 is provided in the guide block 41, and the cross-sectional area of ​​the tapered hole 411 gradually increases from top to bottom; the positioning block 200 is used to insert into the tapered hole 411. In this embodiment, the positioning block 200 includes a positioning boss and a mounting flange connected to the lower end of the positioning boss, wherein: the positioning boss is tapered to match the shape of the tapered hole 411, and is used to be inserted into the tapered hole 411; the mounting flange is fixed to the material box placement table 100 by countersunk screws.

[0042] When the cell box is placed downward on the box placement platform 100, the positioning boss of the positioning block 200 is inserted into the tapered hole 411 from the expanded end of the tapered hole 411, and extends into the tapered hole 411 during the falling process of the cell box. With the cooperation of the positioning block 200 and the tapered hole 411, the box can be accurately placed in the set area.

[0043] On the basis of the above structure, the guide block 41 is made of an elastic material. In this way, during the process of the robotic arm driving the cartridge to fall towards the cartridge placement table 100, the tapered hole 411 can deform to a certain extent, and a small positional error between the cartridge and the cartridge placement table 100 is accommodated through the elastic deformation of the guide block 41. After the robotic arm leaves the cartridge, the plurality of guide blocks 41 return to their initial forms, enabling the positioning block 200 to be smoothly inserted into the tapered hole 411.

[0044] Continue to refer to Figure 7 , the positioning structure 4 further includes a magnet 42, and the magnet 42 is clamped between the bottom plate 1 and the guide block 41; the magnet 42 can be adsorbed and connected to the positioning block 200, thereby further restricting the position of the cartridge relative to the cartridge placement table 100, so as to facilitate the sorting or picking and placing of the battery wafers in the cartridge.

[0045] In the above structure, the guide block 41 can be embedded at the bottom of the bottom plate 1 by means of clamping, deformation pressing, screwing, gluing, etc.; a groove for accommodating the magnet 42 is provided on the upper end surface of the guide block 41. After the guide block 41 is embedded in the bottom plate 1, the magnet 42 is clamped between the bottom plate 1 and the guide block 41, thus realizing the fixed installation of the magnet 42.

[0046] On the basis of the above structure, a threaded through hole is formed in the positioning block 200, and a Hall sensor 400 is screwed in the threaded through hole. The Hall sensor 400 can sense the magnet 42, so that it is possible to judge whether the material box is in place according to the detection result of the Hall sensor 400. Compared with the method of using an optoelectronic sensor to detect whether the material box is in place, using the Hall sensor 400 can eliminate the influence of other substances on the detection result and improve the accuracy of the detection result.

[0047] In this embodiment, the bottom plate 1 and the side plate 2 are integrally formed by an injection molding process. The above setting simplifies the processing procedure of the cartridge, and using a plastic material can reduce the weight of the cartridge, so as to facilitate the handling of the cartridge.

[0048] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
