DETAILED DESCRIPTION

[0035] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] In the photovoltaic module manufacturing process, material boxes are frequently used as containers to store the solar cells. Material boxes come in various types, one type of which includes at least a base plate, a backing plate, a vertical plate, and belts. Each belt is looped around the inside and outside of the vertical plate, and the backing plate is fixedly connected to the inner side of all the belts. However, this type of material box is only suitable for one type of solar cell size, has poor versatility, and cannot be used to accommodate solar cells of other sizes.

[0037] In view of this, such as Figures 1-2 This application provides a material box, including a base plate 1, a pad plate 2, upright plates 3, a belt 4, and a fixing block 5. At least one upright plate 3 is installed on each edge of the base plate 1. At least one first groove 21 is provided on each of the four edges of the pad plate 2. A first hole 211 is provided on each side of the bottom of the first groove 21. The bottom of the first groove 21 also has a clearance groove 212 for avoiding the upright plate 3, located between the two first holes 211. The belt 4 loops around the inner and outer sides of the upright plate 3. The fixing block 5 is fixedly connected to the inner belt body 41 of the belt 4. The two ends of the fixing block 5 are respectively fixedly connected to the pad plate 2 through two first holes 211. The upper surface of the pad plate 2 is used to support multiple sheets. That is, a storage space for storing sheets is formed between the pad plate 2 and the upright plate 3. At least two second holes 11 are provided at intervals on each edge of the bottom plate 1. At least one second hole 11 is a waist hole extending in a direction perpendicular to the edge of the bottom plate 1. The upright plate 3 is fixedly installed on the bottom plate 1 through the second holes 11.

[0038] The first hole 211 is a waist hole whose extension direction is perpendicular to the edge of the pad 2 where the first groove 21 is located; or,

[0039] The first hole 211 includes a plurality of first sub-holes, which are arranged along the edge of the pad 2 where the first groove 21 is located.

[0040] With the above configuration, multiple solar cells are supported on the pad 2. On the one hand, when loading or unloading cells, the pad 2 is lowered or raised, and the inner belt 41 of the belt 4 on the upright plate 3 remains relatively stationary, thus avoiding wear on the edge of the solar cell by the inner belt 41. On the other hand, the upright plate 3 is adjustablely connected to the pad 2 and the base plate 1, so the size of the cell storage space can be adjusted to accommodate more sizes of cells.

[0041] Continue to refer to Figure 1Since the fixed block 5 has a certain volume, in order to increase the number of battery pieces as much as possible, the fixed block 5 can be sunk into the first groove 21, that is, the width of the fixed block 5 is not greater than the groove width of the first groove 21. At the same time, in order to prevent the upper surface of the fixed block 5 from being still higher than the bearing surface of the pad 2 and contacting and damaging the bottommost material piece of the storage space when the pad 2 is at the lowest position, the height of the fixed block 5 should be set to be not higher than the groove depth of the first groove 21.

[0042] As Figure 2 , the fixed block 5 includes a fixed block body 51 and a fixed piece 52, the fixed piece 52 is provided with two through holes for screwing, and the fixed block 5 is provided with two screw holes corresponding to the two through holes on the side facing the fixed piece 52, and the distance between the two through holes is greater than the width of the belt 4 to prevent interference. The fixed block body 51 and the fixed piece 52 are located on both sides of the inner belt body 41 of the belt 4, and the inner belt body 41 is clamped and fixed by screws, so that the pad 2 and the belt 4 form a fixed connection. When the pad 2 is raised and lowered, the inner belt body 41 is relatively stationary.

[0043] As Figure 3 , in order to facilitate the installation of the screws of the fixed block 5, the stand 3 is provided with two third holes 31. Specifically, when installing the screws, the two third holes 31 correspond to the positions of the two through holes and the two screw holes, and then the two screws are respectively sent into the two third holes 31, and then the screws are continuously pushed using a wrench until the screws pass through the through holes, and finally the screws are screwed into the screw holes using a wrench, so as to realize the fixation of the inner belt body 41. The two third holes 31 can be arranged at any height position of the stand 3, but in order to facilitate installation, the two third holes 31 correspond to the positions of the through holes and the screw holes when the pad 2 is at the lowest position and contacts the bottom plate 1.

[0044] Continuing to refer to Figures 1-3 , the upper end and the lower end of each stand 3 are provided with a roller groove 32, and the stand 3 further includes two groups of wheel shafts 33 and drum-shaped rollers 34, the drum-shaped rollers 34 are rotatably installed on the wheel shafts 33, each group of wheel shafts 33 and drum-shaped rollers 34 are arranged in two roller grooves 32 respectively, and the two drum-shaped rollers 34 are used to install the belt 4.

[0045] In order to prevent the stand 3 from being deflected during installation, maintenance or use, as Figure 1 and Figure 3 , the lower end of the stand 3 is provided with a guide protrusion 35, and at the same time, the bottom plate 1 is further provided with a guide groove 12 which is matched in shape with the guide protrusion 35, and the guide protrusion 35 is in the guide groove 12 and can slide along the guide groove 12. The width of the guide groove 12 is basically the same as the width of the guide protrusion 35, so the stand 3 will not be deflected.

[0046] In some cases, the material box can be placed on the conveying mechanism and conveyed by the conveying mechanism to realize the transfer of the material pieces. As Figure 4The cross section of the bottom plate 1 and the wear-resistant guide plate 16 arranged on the downward surface of the bottom plate 1, and the conveying mechanism. The conveying mechanism generally includes a conveying belt 13, a conveying belt support 14, a driving mechanism for driving the conveying belt 13 to rotate circularly, and the conveying belt support 14 for providing support for the conveying belt 13 to prevent the conveying belt 13 from falling. For ease of observation, Figure 4 The bottom plate 1 of the cartridge is separated from the conveying belt 13 during conveying, and the bottom plate 1 of the cartridge is placed on the conveying belt 13 during conveying. As can be seen, when the cartridge is placed on the conveying mechanism, the width of the wear-resistant guide plate 16 is substantially the same as the distance between the two conveying belt 13 supports, which realizes the limiting cooperation without affecting the conveying and avoids the sliding or even overturning of the cartridge. Alternatively, as shown in Figure 5 In another embodiment, two wear-resistant guide plates 16 are arranged on the outer sides of the two conveying belt 13 supports, and the wear-resistant guide plates 16 also form limiting cooperation with the conveying belt 13 supports. At this time, the distance between the inner sides of the two wear-resistant guide plates 16 is substantially equal to the distance between the outer sides of the two conveying belt 13 supports, which realizes the limiting cooperation without affecting the conveying and also avoids the sliding or even overturning of the cartridge.

[0047] Obviously, the wear-resistant guide plate 16 forms contact with the conveying belt 13 supports on both sides, which realizes the purpose of limiting cooperation. Other embodiments of the wear-resistant guide plate 16 are not listed one by one, and a person skilled in the art can make a routine selection according to the actual situation.

[0048] When the conveying mechanism conveys multiple cartridges, the multiple cartridges are arranged in sequence along the conveying direction. In some cases, the conveying mechanism includes a blocking cylinder, and the driving end of the blocking cylinder needs to be extended upward by a predetermined distance to be higher than the conveying plane, so as to block the cartridge coming from the front. If the distance between adjacent cartridges is too small, the driving end will be pushed against the bottom plate 1 of the cartridge when it is extended. Therefore, as shown in Figure 6 At least one stop 15 is arranged on the edge of the bottom plate 1 perpendicular to the conveying direction of the cartridge. In the drawings, two stops 15 are arranged on the edge. During conveying, the adjacent cartridges abut against each other through the stops 15, so as to maintain the distance between the two bottom plates 1 and leave a position for the driving end of the blocking cylinder.

[0049] After the cartridge is sent to the loading station, the sheet is taken out from the cartridge, and after the taking is completed, the center of the pad 2 is provided with a reflective plate 22 in order to timely judge that there is no sheet on the pad 2. As shown in Figure 7 The reflective plate 22 can be arranged in the center of the pad 2 in an embedded manner. Specifically, when the sheet in the storage space is taken out, the reflective plate 22 is exposed. The detection member arranged above includes a light source and a receiver. The light emitted by the light source irradiates on the reflective plate 22, and the reflective plate 22 reflects the light to the receiver. After the receiver receives the light, a signal is sent to the control system, and the taking operation is ended.

[0050] Continuing to refer toFigure 7 The surface of the cushion plate 2 is also provided with a soft buffer layer 23 for flexible bearing of the battery pieces to prevent the battery pieces from being broken. Figure 1 A handle 6 is arranged at each of the opposite edges of the bottom plate 1 to facilitate workers or carrying mechanisms to take and place the material box.

[0051] To reduce the weight, the cushion plate 2 and the bottom plate 1 can be provided with a plurality of through holes or blind holes for weight reduction to reduce the burden of workers, conveying mechanisms or carrying mechanisms.

[0052] The above has described the present application in sufficient detail with certain particularity. The description contains several embodiments, and at least two embodiments can be combined arbitrarily without conflict. Moreover, those skilled in the art should understand that the description in the embodiments is only exemplary, and all changes made without departing from the true spirit and scope of the present application should belong to the protection scope of the present application. The scope of protection claimed by the present application is defined by the claims, not by the above description of the embodiments.
