Description

Technical Field

[0001] This utility model belongs to the field of solar cell manufacturing technology, specifically relating to a cell feeding machine and an air knife mechanism. Background Technology

[0002] In the photovoltaic industry, solar cells require various automated equipment for transfer and testing during the inspection and testing process. Solar cells are typically stored in stacks in bins, and a loader uses suction cups to pick them up one by one and transfer them to subsequent processes. However, due to the high flatness of the solar cell surface and the existence of electrostatic adsorption, stacked cells are prone to sticking together (i.e., multiple cells adhering to each other). If directly picked up, the suction cup may pick up multiple cells at once, causing equipment jamming, transfer errors, or even cell damage, severely impacting production efficiency and product yield.

[0003] Currently, in order to solve the problem of cell adhesion, for example, Chinese patent with authorization announcement number CN115069589B discloses a single crystal cell sorting machine, which uses a blower mechanism to generate airflow to blow the cells a certain distance, assisting the robotic arm to pick up the cells and perform preliminary separation of the cells before testing. However, this existing technology has obvious limitations: when the equipment space layout is compact, especially when multiple rows of solar cells need to be processed at the same time (such as feeding 4 cells at the same time), due to the narrow spacing between adjacent material boxes, the general blowing mechanism cannot be installed between the two material boxes, the airflow cannot penetrate into the narrow gap, there are dead corners, and some solar cells cannot be effectively blown away.

[0004] Therefore, a cell feeding machine and air knife mechanism are designed to solve the technical problem in the prior art where, when multiple rows of cells (such as four cells being fed at the same time) are fed, the spacing between adjacent material boxes is narrow, and the airflow generated by the general blowing mechanism cannot reach into the narrow gap, making it difficult to effectively blow away the cells.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0027] Research has revealed that the blower mechanism used in existing technologies to prevent stacked solar cells from sticking together can be problematic when the equipment has a compact layout, especially when multiple rows of solar cells need to be processed simultaneously (such as feeding four cells at the same time). Due to the narrow spacing between adjacent material boxes, the general blowing mechanism cannot be installed between the two material boxes. The airflow penetrates into the narrow gaps, creating dead angles, which results in some solar cells not being effectively blown apart.

[0028] Based on the above research, this disclosure provides a battery cell feeding machine and an air knife mechanism. By setting up a plurality of air knife mechanisms, each air knife mechanism is installed between two adjacent battery cell placement boxes in each material box group. The air knife mechanism blows air vertically downwards to the battery cell placement boxes on both sides of each air knife mechanism, thereby preventing the battery cells from sticking together.

[0029] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] In some embodiments, such as Figure 1 As shown, the operator fixes each pair of cell placement boxes 210 as a group on the upper surface of the base plate 20. Since the distance between the corresponding two groups of material boxes 21 is greater than the distance between the corresponding two cell placement boxes 210 in each group of material boxes 21, according to the number of material box groups 21 placed on the base plate 20, a corresponding number of air knife mechanisms 3 are set on the bracket 1 between adjacent cell placement boxes 210 in each group of material boxes 21. At the same time, a corresponding number of drying mechanisms 4 are installed on the bracket 1 between adjacent groups of material boxes 21. Depending on the different gaps, air is blown into each cell placement box 210 to prevent them from sticking together.

[0033] In some embodiments, such as Figure 2 and Figure 3As shown, after each material box group 21 is installed in place, the operator connects one end of the air pump pipe 310 to the corresponding air inlet 314 and the other end to the output end of the air pump. The gas discharged from the air pump is introduced into the air duct 312 opened in the air plate 30 through the air inlet 314. As shown in the figure, the air outlet of the air duct 312 is vertically downward. When the air duct plate 313 covers the outer wall of the air plate 30, it fits the air duct 312. The gas is discharged from the air outlet of the air duct 312 along the F1 direction. Preferably, each air plate 30 is provided with two blowing components 31 on the outer wall facing the corresponding battery cell placement box 210 to blow air on each battery cell in the corresponding battery cell placement box 210 to prevent them from sticking together. Since the width of the air panel 30 is small, it is difficult to process the air duct 312 inside the air panel 30. Therefore, each air duct 312 is opened on the outer wall of the air panel 30 and covered by the air duct plate 313. The air duct plate 313 is connected to the air panel 30 by means including but not limited to magnetic attraction.

[0034] In some embodiments, such as Figure 4 and Figure 5 As shown, for the drying mechanism 4 between adjacent material box groups 21, the connecting piece 41 in each drying mechanism 4 is fixed on the bracket 1, and the corresponding fixing plate 40 is connected to the connecting piece 41. The auxiliary block 420 is connected to the fixing plate 40 by screws, including but not limited to screws. Each pressure plate 421 is covered on the surface of the corresponding auxiliary block 420 to close the notch 423. At this time, the air outlet direction of the notch 423 is towards the corresponding battery cell placement box 210 in the corresponding material box group 21. One end of the air duct 422 is connected to the corresponding auxiliary block 420, and the other end is connected to the output end of the air pump. Thus, the gas pumped out of the air pump enters the interior of the auxiliary block 420 through the air duct 422 and is finally discharged from the air outlet direction of the notch, i.e., along the F2 direction, and blown towards the corresponding battery cell placement box 210.

[0035] In summary, for the larger gaps between adjacent material box groups 21, a drying mechanism 4 is used to blow air directly toward the side wall of the cell placement box 210 in the corresponding material box group 21 using the notch 423, so as to avoid the cells sticking together in the cell placement box 210. For the smaller gaps between adjacent cell placement boxes 210 in each material box group 21, an air knife mechanism 3 is used, with the air duct 312 opened on the side wall of the air plate 30, blowing air vertically downwards, so that the airflow extends into the narrow gap between adjacent cell placement boxes 210, thus meeting the drying requirements of the cells.

[0036] It should be noted that the air pump mentioned above is existing technology, and its working principle and connection method will not be elaborated on here.

[0037] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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.

[0038] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0039] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0040] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
