Abstract
Description
Technical Field
[0001] This utility model relates to the field of caching device technology, and specifically to a caching device. Background Technology
[0002] In the production of solar cells on an assembly line, buffer devices need to be set up at appropriate workstations to temporarily store the cells and avoid material shortages or stockpiles.
[0003] A solar cell buffer device includes a buffer bracket, multiple first support plates, multiple second support plates, and a lifting rod. The buffer bracket is a rectangular structure, including a first column and a second column arranged opposite each other. Multiple first mounting slots and second mounting slots are respectively formed on the inner sides of the first and second columns. The multiple first mounting slots are evenly spaced along the height direction of the first column. The multiple second mounting slots are also evenly spaced along the height direction of the second column. First and second mounting slots of the same level are at the same height. Multiple first support plates are detachably inserted into the first mounting slots, one by one. Multiple second support plates are detachably inserted into the second mounting slots, one by one. The first and second support plates of the same level are coplanar, thus forming a solar cell bearing surface. The solar cell buffer device cooperates with a conveying device for loading and unloading. During loading, the conveying device transports the battery cells to the top of the first and second support plates. The lifting rod drives the buffer bracket to rise, and the corresponding first and second support plates support the battery cells to achieve buffering. During unloading, the lifting rod drives the buffer bracket to fall, and the first and second support plates fall, causing the battery cells to fall onto the conveying device and be transported to the subsequent process by the conveying device with the help of friction.
[0004] Although the first and second support plates in the aforementioned battery cell buffer device are detachably connected to the first and second columns respectively, facilitating subsequent replacement, their shortcomings are as follows: during the loading and unloading process, the first and second support plates only move up and down with the buffer bracket, making it easy for dust and other foreign objects to remain on the surfaces of the first and second support plates. In addition, the battery cells slide against the first and second support plates, resulting in high friction, and dust and other foreign objects remaining on the first and / or second support plates can easily damage the surface of the battery cells.
[0005] In view of the above shortcomings, it is necessary to design a new caching device to overcome these shortcomings. Utility Model Content
[0006] Therefore, the technical problem to be solved by this utility model is that in the existing battery cell buffer device, foreign objects such as dust are easy to stay on the surface of the first support plate and the second support plate.

Foreign objects such as dust can easily damage the surface of the battery cell. Therefore, this utility model provides a buffer device.

[0021] Furthermore, the first snap-fit member is flat; the first locking member includes a first upright plate, two first wing plates, and two first extension plates.

In this way, the first latching member is not prone to deformation or displacement after long-term use. Similarly, because the second insert plate of the second latching member is inserted into the gap between the second folding plate and the second wing plate on the second locking member, the second insert plate can be supported by the second extension plate and the second folding plate in both horizontal and vertical directions. In this way, the second latching member is not prone to deformation or displacement after long-term use. Since the first latching member and the second latching member are not prone to deformation or displacement, the first roller and the second roller can be better maintained in the preset position. Ultimately, the buffered item can move along the bearing surface formed by the first roller and the second roller in the preset moving direction, ensuring the smooth and safe conveying of the buffered item.
[0031] 3.

[0044] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0045] In the description of this utility model, it should be noted that the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0046] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0047] like Figures 2 to 9As shown, this utility model provides a buffer device A, specifically a battery cell buffer device. Of course, it can also be used for buffering other sheet-like components, or smaller-sized parts can be stacked in a storage box, with the storage box buffered in the buffer device A. The buffer device A will be described below using a battery cell as an example.
[0048] The buffer device A includes a lifting screw 2, a buffer bracket 1 connected to the lifting screw 2, and multiple rollers.
[0049] The buffer support 1 includes a first baffle 11 and a second baffle 12 that are arranged opposite each other and extend vertically. The buffer support 1 also includes a top plate and a bottom plate. The first baffle 11 and the second baffle 12 are supported between the top plate and the bottom plate. Figure 2 As shown, in this embodiment, there are two first baffles 11 and two second baffles 12, and also two buffer cavities. Specifically, one first baffle 11 and one second baffle 12, together with a top plate and a bottom plate, form a buffer cavity. Of course, the number of buffer cavities can be one or more; this is not specifically limited and can be set according to actual needs. Figure 2 From the perspective of the top plate, the left end is connected to the lifting screw 2. In this way, when the lifting screw 2 is driven by the drive mechanism 7 to make lifting and lowering movements, the buffer bracket 1 also makes lifting and lowering movements accordingly.
[0050] The inner side of the first baffle 11 is provided with a plurality of first mounting slots 111 (e.g., Figure 6 (As shown). Multiple first mounting slots 111 are equally spaced along the height direction of the first baffle 11. Multiple second mounting slots (not marked) are also provided on the inner side of the second baffle 12. The multiple second mounting slots are equally spaced along the height direction of the second baffle 12. Figure 2 From a bottom-up perspective, the multiple first mounting slots 111 are defined as first-level first mounting slots, second-level first mounting slots, ..., N-level first mounting slots; and the multiple second mounting slots are defined as first-level second mounting slots, second-level second mounting slots, ..., N-level second mounting slots. The first-level first mounting slots and first-level second mounting slots are at the same height, the second-level first mounting slots and second-level second mounting slots are at the same height, ..., the N-level first mounting slots 111 and N-level second mounting slots are at the same height.
[0051] There are multiple rollers. For ease of explanation, the roller connected to the first baffle 11 is defined as the first roller 3, and the roller connected to the second baffle 12 is defined as the second roller 4. Since there are multiple first mounting slots 111 and multiple second mounting slots, there are also multiple first rollers 3 and multiple second rollers 4.
[0052] Corresponding to the first-level first mounting slot, the second-level first mounting slot, ..., the Nth-level first mounting slot, multiple first rollers 3 are respectively defined as first-level first rollers, second-level first rollers, ..., the Nth-level first rollers. Similarly, multiple second rollers 4 are respectively defined as first-level second rollers, second-level second rollers, ..., the Nth-level second rollers. The first rollers 3 are mounted on the first baffle 11 facing the inner side of the second baffle 12, with the rotation axis of the first rollers 3 facing the side where the second baffle 12 is located. The second rollers 4 are mounted on the second baffle 12 facing the inner side of the first baffle 11, with the rotation axis of the second rollers 4 facing the side where the first baffle 11 is located. The top surfaces of the first rollers 3 and the second rollers 4 at the same height form a bearing surface for supporting the battery cells, and the bearing surface is parallel to the bottom plate.
[0053] Regarding the connection method between the first roller 3 and the first baffle 11, and the connection method between the second roller 4 and the second baffle 12:
[0054] In the first embodiment, the buffer device A further includes a first locking member 6 and a second locking member (not labeled). The first connecting member and the second connecting member are respectively a first snap-fit member 5 and a second snap-fit member (not labeled). The first snap-fit member 5 is interlocked with the first locking member 6, and the second snap-fit member is interlocked with the second locking member. The first locking member 6 and the second locking member are inserted into the first mounting slot 111 and the second mounting slot respectively from the front side of the buffer device A. The arrangement of the first mounting slot 111 and the second mounting slot facilitates quick positioning of the first locking member 6 and the second locking member, improving installation efficiency, and also helps to ensure that the first roller 3 on the first baffle 11 and the corresponding second roller 4 on the second baffle 12 are at the same height.
[0055] Specifically, such as Figures 2 to 6 As shown, the first latching member 5 is in the shape of a folded "U", including a first side plate 51 and two first insert plates 52. The two first insert plates 52 are formed by bending and extending from both ends of the first side plate 51 toward the same side. The fixed shaft of the first roller 3 is detachably connected to the first side plate 51. The first locking member 6 includes a first upright plate 61, two first wing plates 62, two first extension plates 63, and two first folding plates 64. The two first wing plates 62 are formed by bending and extending from both ends of the first upright plate 61 toward the same side, the two first extension plates 63 are formed by bending and extending from the ends of the two first wing plates 62 respectively, and the two first folding plates 64 are formed by bending and extending from the ends of the two first extension plates 63 toward the first upright plate 61 respectively. The first insert plate 52 is inserted into the gap between the first wing plate 62 and the first folding plate 64. During use, the first extension plate 63 and the first folding plate 64 can support the first insert plate 52 in the horizontal and vertical directions respectively. In this way, the first snap-fit part 5 is not easy to deform or shift during long-term use, and the first roller 3 can be better kept in the preset position.
[0056] The second locking component is also shaped like a folded "U," including a second side plate and two second insert plates. The two second insert plates are formed by bending and extending from both ends of the second side plate towards the same side. The fixing shaft of the second roller 4 is detachably connected to the second side plate. The second locking component includes a second upright plate, two second wing plates, two second extension plates, and two second folding plates. The two second wing plates are formed by bending and extending from both ends of the second upright plate towards the same side; the two second extension plates are formed by bending and extending relative to each other from the ends of the two second wing plates; and the two second folding plates are formed by bending and extending from the ends of the two second extension plates towards the second upright plate. The second insert plates are inserted into the gap between the second wing plates and the second folding plates. During use, the second extension plates and the second folding plates can support the second insert plates in both horizontal and vertical directions, respectively. This prevents the second locking component from deforming or shifting during prolonged use, thus allowing the second roller 4 to be better maintained in its preset position. Since the first roller 3 and the second roller 4 can be better maintained in the preset position, the bearing surface of the battery cell is stable. During the transportation process, the battery cell can move along the bearing surface formed by the first roller 3 and the second roller 4 in the preset direction of movement, ensuring the smoothness and safety of the battery cell transportation.
[0057] In the second embodiment, the first snap-fit member 5 and the first locking member 6 may also be Figure 7 The structure shown is such that the first snap-fit member 5 and the second snap-fit member are both flat plates, and the first insert plate 52 and the second insert plate are removed respectively. Correspondingly, compared with the first locking member 6 and the second locking member in the first embodiment, the first folding plate 64 and the second folding plate are removed respectively.
[0058] In the third embodiment, as Figure 8 As shown, the two ends of the first connector are respectively interfering with and snapped into the top and bottom walls of the first mounting groove 111, and the two ends of the second connector are respectively interfering with and snapped into the top and bottom walls of the second mounting groove. To improve the connection's firmness, the first and second connectors are also fixedly connected to the first baffle 11 and the second baffle 12 respectively using corresponding fasteners. The first roller 3 and the second roller 4 are detachably connected to the first and second connectors respectively. Of course, the first and second connectors can also be welded to the first baffle 11 and the second baffle 12 respectively.
[0059] In the fourth embodiment, as Figure 9 As shown, the top and bottom of the first mounting groove 111 are respectively provided with first limiting grooves 1111, and the top and bottom of the first connector enter the two first limiting grooves 1111 respectively. The top and bottom of the second mounting groove are respectively provided with second limiting grooves, and the top and bottom of the second connector enter the two second limiting grooves respectively.
[0060] Unlike the previous four embodiments, in the fifth embodiment (not shown), the first connecting member and the second connecting member are not provided, and the first roller 3 and the second roller 4 are directly and detachably mounted on the first baffle 11 and the second baffle 12, respectively.
[0061] The working process of the cache device A provided by this utility model is described below:
[0062] During loading, the conveying device (not shown) transports the battery cells above the first roller 3 and the second roller 4. The lifting screw 2 drives the buffer support 1 to rise, and the corresponding first roller 3 and second roller 4 support the battery cells. The conveying device continues to push the battery cells into the buffer device A using static friction. The battery cells push the first roller 3 and the second roller 4 to rotate, thereby continuously moving the battery cells into the buffer device A until the battery cells are removed from the conveying device, thus achieving the buffering of the battery cells. During unloading, the lifting screw 2 drives the buffer support 1 to descend, and the first roller 3 and the second roller 4 descend, causing the battery cells to fall onto the conveying device. The conveying device, using static friction, continuously moves the battery cells along the conveying device. Figure 3 The cells move out of the buffer device A in the direction indicated by the middle arrow until they detach from the buffer device A and are then transported to the subsequent process by the conveying device.
[0063] As can be seen from the working process of the buffer device A, during the feeding and unloading process, the first roller 3 and the second roller 4 will rotate under the drive of the battery cells. During the rotation, dust and other foreign objects on the first roller 3 and the second roller 4 will fall off or be scraped off by the battery cells, reducing the impact of dust and other foreign objects on the battery cells. In addition, the battery cells are in rolling contact with the first roller 3 and the second roller 4. The rolling friction is less than the sliding friction, so the impact of dust and other foreign objects on the battery cells can be further reduced.
[0064] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the embodiments. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
