[0002] Solar cells are a type of photoelectric semiconductor wafer that uses sunlight to generate electricity directly. After being neatly arranged, the cell group needs to be packaged. In order to protect the cells, sulfur-free paper and hollow boards need to be placed at the upper and lower ends of the cell group before packaging. The sulfur-free paper is used to isolate the cells from the influence of air, and the hollow board is used to protect the cells from damage.

[0003] Existing cell packaging equipment is usually equipped with two material boxes for storing sulfur-free paper and hollow plates respectively. Since the thickness of sulfur-free paper is less than that of hollow plates, when the heights of the two material boxes are the same, the number of hollow plates stored is less than the number of sulfur-free paper stored, resulting in the inability to refill the two material boxes at the same time, increasing the manual labor; if the two material boxes are set to different heights, the height difference between the two material boxes needs to be compensated during assembly, resulting in a complex installation structure of the material boxes. Utility Model Content

[0038] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0040] It should be noted that in the description of the present invention, 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 ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In existing battery cell packaging equipment, when the hollow board storage box and the sulfur-free board storage box have the same height, the number of hollow boards stored is less than the number of sulfur-free papers stored, resulting in the two boxes being unable to be refilled at the same time, increasing the workload.

[0042] Based on this, the utility model provides a material box structure, referring to Figure 1 The material box structure includes a material box body 1, which has a plurality of accommodating cavities. The plurality of accommodating cavities are divided into a plurality of first accommodating cavities 11 for storing sulfur-free paper and a plurality of second accommodating cavities 12 for storing hollow boards. The number of the first accommodating cavities 11 is less than the number of the second accommodating cavities 12.

[0043] In the above structure, since the number of the first accommodating chambers 11 for storing sulfur-free paper is less than the number of the second accommodating chambers 12 for storing hollow boards, the sulfur-free paper and the hollow boards can be used up at the same time by reasonably setting the number of the first accommodating chambers 11 and the second accommodating chambers 12, so that the sulfur-free paper and the hollow boards can be replenished at the same time, avoiding frequent replenishment by the staff and reducing the manual labor. In addition, the present application integrates two material boxes for storing sulfur-free boards and hollow boards in the existing equipment, that is, the material box body 1 can store sulfur-free paper and hollow boards at the same time, which is convenient for the staff to carry materials.

[0044] In this embodiment, there is one first accommodating cavity 11 and two second accommodating cavities 12. The number of the first accommodating cavity 11 and the second accommodating cavity 12 is reasonably set according to actual use requirements, and the number of the two meets the requirement that the storage amount of sulfur-free paper and the storage amount of hollow board are close.

[0045] In this embodiment, a plurality of accommodating cavities are arranged side by side, and two adjacent accommodating cavities share a side cavity wall.

[0046] Furthermore, each side cavity wall of the accommodating cavity is provided with a notch, and the notch extends from the open end of the accommodating cavity to the bottom surface of the accommodating cavity. Specifically, each side cavity wall of the first accommodating cavity 11 is provided with a first notch 111, and each side cavity wall of the second accommodating cavity 12 is provided with a second notch 121; for the side cavity wall shared by the first accommodating cavity 11 and the second accommodating cavity 12, the first notch 111 and the second notch 121 overlap. The provision of the notch facilitates the staff to take and put materials into the accommodating cavity, while saving the manufacturing materials of the material box body 1, reducing the production cost and the weight of the material box body 1.

[0047] Reference Figure 1 and Figure 2 The material box structure also includes multiple groups of lifting components 2, which correspond one by one to the multiple accommodating chambers, and each group of lifting components 2 is used to lift the materials in the corresponding accommodating chamber.

[0048] Specifically, each lifting assembly 2 includes a material receiving plate 21 and a lifting cylinder 22, wherein:

[0049] The material receiving plate 21 is disposed in the corresponding accommodating cavity and is used to hold the material;

[0050] The piston rod end of the lifting cylinder 22 can extend into the corresponding accommodating cavity and drive the receiving plate 21 to move up and down.

[0051] In each lifting assembly 2, the lifting cylinder 22 is arranged below the corresponding accommodating chamber, and the bottom wall of the accommodating chamber is provided with a through hole for the piston rod of the lifting cylinder 22 to pass through. When the material box body 1 is in place, the piston rod of the lifting cylinder 22 passes through the through hole on the bottom wall of the accommodating chamber and contacts the material receiving plate 21, and the lifting cylinder 22 pushes the material receiving plate 21 to move upward, thereby achieving the purpose of lifting the material.

[0052] During the operation of the material box structure, when the material in the upper layer of the containing cavity is taken away, the lifting cylinder 22 pushes the material receiving plate 21 upward, thereby lifting the material, which makes it convenient to take the material.

[0053] Continue to refer to Figure 1 The material box structure also includes a plurality of material level detection components 3, and the plurality of material level detection components 3 correspond one to one with the plurality of accommodating cavities;

[0054] Each group of material level detection components 3 includes at least one proximity switch, which is arranged at the periphery of the corresponding accommodating cavity, and a notch for detection by the proximity switch is opened on the side cavity wall of the accommodating cavity.

[0055] In this embodiment, the material level detection assembly 3 corresponding to the first accommodating cavity 11 is arranged outside the first notch 111, and the material level detection assembly 3 corresponding to the second accommodating cavity 12 is arranged outside the second notch 121. The arrangement of the first notch 111 and the second notch 121 ensures that there is no obstruction between the sensing surface of the proximity switch and the material in the cavity, which facilitates proximity switch detection.

[0056] A proximity switch is a position switch that does not require direct mechanical contact with moving parts. When an object approaches the switch sensing surface to the action distance, the switch will be activated, thereby obtaining the material level signal in the containing chamber and transmitting the material level signal to the control system; the control system controls the action of the lifting component 2 according to the material level signal, thereby achieving the purpose of automatically lifting the material.

[0057] Specifically, there are two proximity switches, namely a first proximity switch 31 and a second proximity switch 32. The first proximity switch 31 and the second proximity switch 32 are respectively arranged at the upper and lower parts of the corresponding accommodating cavity, wherein: the first proximity switch 31 is used to detect whether the top layer of material is in place, and the second proximity switch is used to detect whether the material receiving plate 21 is in place.

[0058] Taking one of the accommodating chambers as an example, the working process of the material box structure is as follows: in the initial state, the first proximity switch 31 detects that the top layer of material is in place, and the second proximity switch 32 detects that the material receiving plate 21 is in place. At this time, the accommodating chamber is in a full material state; then, the material on the top layer in the accommodating chamber is removed manually or by a suction cup. At this time, the first proximity switch 31 cannot detect the material; then, the lifting cylinder 22 pushes the material receiving plate 21 to rise by the thickness of a material. At this time, the first proximity switch 31 re-detects that the top layer of material is in place, so that the material can be taken out again, and so on until all the materials are taken out; when the lifting cylinder 22 reaches the maximum stroke and the first proximity switch 31 cannot detect the material, it means that all the materials are taken out. At this time, the piston rod of the lifting cylinder 22 descends and drives the material receiving plate 21 to descend until the second proximity switch 32 detects that the material receiving plate 21 is in place. After that, the equipment issues an alarm to remind the staff to replenish the materials in time.

[0059] Through the above process, the height of the material picked up is consistent each time, which improves the accuracy of material picking up and can also remind the staff to replenish the material in time to avoid affecting the production progress.

[0060] In this embodiment, the first proximity switch 31 is a photoelectric sensor, specifically a beam-type photoelectric sensor. The beam-type photoelectric sensor includes a transmitter and a receiver that are separately arranged, and the transmitter and the receiver are relatively arranged on both sides of the accommodating cavity. When there is material between the transmitter and the receiver of the first proximity switch 31, the first proximity switch 31 detects that the top material is in place; when there is no material between the transmitter and the receiver of the first proximity switch 31, the first proximity switch 31 cannot detect the material, and the control system controls the lifting cylinder 22 to lift the material after receiving the signal of the first proximity switch 31.

[0061] In other embodiments, the first proximity switch 31 may also be a reflective photoelectric sensor.

[0062] Optionally, the second proximity switch 32 is a photoelectric sensor or a Hall sensor. When the second proximity switch 32 is a photoelectric sensor, the first proximity switch 31 and the second proximity switch 32 have the same structure.

[0063] Reference Figure 3 When the second proximity switch 32 is a Hall sensor, the material level detection assembly 3 further includes a magnet 35 mounted on the corresponding material receiving plate 21. Optionally, the magnet 35 is fixed to the side of the material receiving plate 21 close to the Hall sensor by screws. Compared with the photoelectric sensor, the Hall sensor can sense whether the magnet 35 is in place, and it is not affected by materials or other substances, which can avoid the occurrence of false detection.

[0064] Reference Figure 2 and Figure 3 , the material level detection assembly 3 also includes a first mounting rod 33 and at least one first connecting block 34, wherein:

[0065] The length direction of the first mounting rod 33 is parallel to the height direction of the accommodating cavity;

[0066] The first connection block 34 is slidably mounted on the first mounting rod 33 , and the proximity switches are mounted on the first connection block 34 in a one-to-one correspondence.

[0067] On the basis of the above structure, the proximity switch is slidably mounted on the corresponding first connecting block 34 along a direction away from or approaching the accommodating cavity.

[0068] Reference Figure 3 The first connecting block 34 is provided with a first mounting hole 341 and a second mounting hole 342, wherein: the first mounting hole 341 is sleeved on the first mounting rod 33, a notch is provided in the hole wall of the first mounting hole 341, and a locking screw is provided at the notch; a proximity switch is installed in the second mounting hole 342, a notch is also provided in the hole wall of the second mounting hole 342, and a locking screw is provided at the notch.

[0069] When you need to adjust the position of the proximity switch, loosen the locking screw and move the proximity switch up, down, forward and backward to put it in the appropriate position.

[0070] It should be noted that when the proximity switch is a through-beam photoelectric sensor, the material level detection assembly 3 further includes a second mounting rod and at least one second connecting block slidably mounted on the second mounting rod, and the first mounting rod 33 and the second mounting rod are respectively arranged on opposite sides of the mounting cavity; the transmitter of the proximity switch is mounted on the first connecting block 34, and the receiver of the proximity switch is mounted on the second connecting block. The structure of the second mounting rod and the second connecting block is the same as that of the first mounting rod 33 and the first connecting block 34, and will not be repeated here.

[0071] Reference Figure 4 A brush 4 is installed on the top of the side cavity wall of the first accommodating cavity 11. The first accommodating cavity 11 is used to store sulfur-free paper. The sulfur-free paper is light in weight. When the top layer of sulfur-free paper is taken out, the lower layer of sulfur-free paper may occasionally be stuck and dragged out. In this embodiment, a brush 4 is installed on the top of the side cavity wall of the first accommodating cavity 11. When the top layer of sulfur-free paper is taken out, the brush 4 can brush off the sulfur-free paper that is stuck to the top layer of sulfur-free paper, thereby avoiding the problem of the lower layer of sulfur-free paper being stuck and dragged out.

[0072] Reference Figure 5 and Figure 6 The material box structure provided in this embodiment is applied in a battery cell packaging device. The battery cell packaging device further comprises a material box placement rack 100, on the upper end surface of which a slide rail 200 is installed, on which a material box body 1 is slidably mounted, and a lifting cylinder 22, a first mounting rod 33 and a second mounting rod are all installed on the material box placement rack 100.

[0073] Since the material box body 1 is slidably mounted on the slide rail 200 , when material replenishment is needed, the staff can simply pull the material box body 1 along the extension direction of the slide rail 200 without carrying the material box body 1 , thereby improving the convenience of material replenishment.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
