Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0048] The post-processing of solar cells, such as material preparation and packaging, is currently still done manually. On the one hand, the labor cost is high, and on the other hand, the manual operation makes it difficult to control the breakage rate during the process.

[0049] In view of this, the present invention provides a battery cell aligning mechanism, which aims to solve the technical problems of high labor costs and difficult to control breakage rates in the current battery cell aligning process. Figures 1 to 4 This is an embodiment of the battery cell aligning mechanism provided by the present invention.

[0050] Please refer to Figures 1 to 3 The battery cell aligning mechanism 100 includes a carrying component 1 and a sorting component 2. The carrying component 1 includes a movably arranged flip platform 11. The flip platform 11 has a first state in which it is horizontally arranged, and a second state in which it is vertically arranged. The flip platform 11 is used for placing the material box 200. The sorting component 2 is provided on the flip platform 11 and is used to be arranged on the side of the material box 200. The sorting component 2 includes a movably arranged pushing portion 21. When the flip platform 11 is in the second state, the pushing portion 21 is located below the material box 200 and can move in the vertical direction. The pushing portion 21 can extend into the material box 200 and contact the edges of the multiple battery cells.

[0051] In the technical solution of the present invention, initially, the flipping platform 11 is in the first state and is overall horizontal. The material box 200 containing multiple scattered battery cells is fixed on the flipping platform 11. At this time, the pushing part 21 is at the side of the material box 200. Then the flipping platform 11 is driven to convert to the second state. At this time, the whole is arranged in an up-down direction. At this time, the pushing part 21 is below the material box 200, and the pushing part 21 is driven to move upward, thereby breaking up multiple battery cells. When the pushing part 21 is downward, the battery cells can fall uniformly on the inner wall of the material box 200 by their own gravity. By controlling the pushing part 21 to repeat the up and down action, the multiple battery cells are finally arranged in order. Then the flipping platform 11 is driven to return to the first state to complete the process. Compared with the existing technology, it saves labor costs, improves the efficiency of the whole piece, and solves technical problems such as the difficulty in controlling the breakage rate of manual arrangement.

[0052] It should be noted that the material box 200 can be combined with the battery cells and then detachably mounted on the flip platform 11 , or the material box 200 can be directly integrated on the flip platform 11 and battery cells can be placed therein each time.

[0053] It is understandable that the present invention does not limit the shape of the material holding box 200. Normally, the material holding box 200 is square, but for ease of positioning, its shape can also be set to other regular or irregular shapes. In this embodiment, a portion of the cavity wall of the material holding box 200 has a corner 210 so as to be able to contact the two adjacent sides of each battery cell. When the flip platform 11 is in the second state, the corner 210 of the material holding box 200 is set downward. In this structural state, when multiple battery cells are broken up and fall, each battery cell is also set with a pointed corner facing downward, so that it can be positioned neatly through the two sides, further ensuring the neat effect. If the material holding box 200 is set in the up and down direction, the flat wall is also in contact with the side of the battery cell, and there is a risk that only one side is neat and the rest of the periphery may still be messy.

[0054] In this embodiment, the material holding box 200 and the battery cells are both square structures. In the second state, one of the tips of the material holding box 200 faces downward, so that the whole is in a diamond shape.

[0055] In order to break up the multiple battery cells, it is necessary to ensure that the pushing portion 21 can extend into the material box 200 and does not interfere with other parts during the reciprocating motion. In one embodiment, a notch 220 is provided on the side of the material box 200 to expose the multiple battery cells in the material box 200, and the pushing portion 21 is movably provided in the notch 220. It is understood that in the second state, the notch 220 should be able to connect the inner cavity and the external space of the material box 200 in the vertical direction, so as to correspond to the vertical movable stroke of the pushing portion 21.

[0056] It is understandable that the opening can be formed by punching holes in the side wall of the material holding box 200, or the peripheral side wall of the material holding box 200 can be arranged into several spaced plate segments to naturally form the notch 220. The present invention does not limit the extension direction of the notch 220, and the extension direction can be consistent with the wall thickness direction of the side wall of the material holding box 200. In this case, in the second state, the corresponding notch 220 does not extend vertically, but extends obliquely, and its spatial size is sufficient for the push portion 21 to be movable through it.

[0057] Furthermore, the arranging assembly 2 includes a bracket 22 and a driving mechanism. The bracket 22 is provided on the flip platform 11 and is provided on the side of the material box 200. The bracket 22 includes two support arms 221 spaced apart. The driving mechanism drives the bracket 22 to move. The two pushing parts 21 are respectively fixed to the two support arms 221. That is, the two pushing parts 21 can move synchronously to achieve a better breaking up effect. When the material box 200 has a corner 210, the two pushing parts 21 should be located on both sides of the corner 210 so as to break up different sides of the battery cells.

[0058] It should be noted that the present invention does not limit the specific form of the driving mechanism. In one embodiment, a motor and a lead screw structure can be provided to drive the bracket 22 to move linearly. In other embodiments, the bracket 22 can also be driven by a cylinder.

[0059] Furthermore, the end surface of the pushing portion 21 is provided with an air hole, which is used to connect to an external air pump to blow air into the material box 200. That is, during the pushing process, air can be blown into the material box 200 all the time, thereby ensuring the battery cells are dispersed effectively by the combination of blowing and pushing, and preventing adjacent battery cells from sticking together.

[0060] When multiple battery cells are placed in a vertical position and are pushed and broken up, due to the limited space between adjacent battery cells, some battery cells may become stuck due to adhesion or tilting, and do not fall naturally, but are propped up, affecting the neatening process. Therefore, in one embodiment, the sorting component 2 also includes a movable pressing part 23. When the flip platform 11 is in the second state, the pressing part 23 corresponds to the upper side of the material box 200. The pressing part 23 can extend into the material box 200 and contact the edges of the multiple battery cells. It can be understood that the pressing part 23 has an opposite movement direction to the pushing part 21, and the pressing part 23 is used to push the battery cells downward to ensure that the battery cells fall neatly.

[0061] It can be understood that the structure of the pressing part 23 can be set to be consistent with the pushing part 21, or different, as long as the two can realize their respective functions respectively. The pressing part 23 and the pushing part 21 can move toward each other at the same time, or they can work at intervals, that is, when the pushing part 21 moves downward, the pressing part 23 extends downward into the material box 200, or when the pushing part 21 moves upward, the pressing part 23 extends downward into the material box 200. The present invention does not impose any restrictions on this.

[0062] Furthermore, the end face of the pressing portion 23 is provided with an air hole, which is used to connect to an external air pump to blow air into the material box 200. That is, during the pressing process, air can always be blown into the material box 200, thereby ensuring the arrangement effect of the battery cells by blowing and pressing and pushing, avoiding the adhesion of adjacent battery cells, or the tilting and jamming of a single battery cell.

[0063] In one embodiment, a plurality of gaps 220 arranged at intervals are provided on the side of the material holding box 200 , and the material pressing portion 23 and the pushing portion 21 are movably arranged in the corresponding gaps 220 .

[0064] In the embodiment of the present invention, the material box 200 is provided with four notches 220 in the circumferential direction, which are respectively staggered with the four corners 210 of the material box 200 , and two pushing parts 21 and two pressing parts 23 are provided.

[0065] In order to prevent the battery cells from falling out during the sorting process, the material box 200 can be designed to be sealed and the end cover can be transparent, so as to prevent the battery cells from falling out while facilitating the observation of the sorting effect. In this embodiment, the material box 200 is open, which is convenient for intuitive observation and the loading and unloading of battery cells. Accordingly, the battery cell tidying mechanism 100 also includes a supporting and pressing component 3 provided on the flip platform 11, and the supporting and pressing component 3 includes a pressure plate 31 that can be movably arranged horizontally and in the up and down directions. The pressure plate 31 is staggered with the pushing portion 21, and the pressure plate 31 is used to extend from the opening of the material box 200 to approach the battery cells exposed in the material box 200. Initially, the pressure plate 31 should correspond to the side of the flip platform 11 so as to avoid interference with the installation of the material box 200. When the flip platform 11 is in the first state, the material box 200 is first fixed, and then the orientation of the pressure plate 31 is adjusted so that it can correspond to the opening of the material box 200. Then, the adjustment is continued so that the pressure plate 31 can be close to the battery cells, but will not fit with the battery cells. This is to prevent the battery cells from falling out when the flip platform 11 is converted to the second state, while ensuring that the battery cells have enough space to move around and be broken up and moved neatly.

[0066] The present invention does not limit the specific structure of the pressing plate 31 , which may be a regular or irregular shape, and is used to correspond to the center or edge of the battery cell.

[0067] In one embodiment, please refer to Figure 2 The pressure plate 31 includes a first plate segment 311 and a second plate segment 312 arranged at an angle. The first plate segment 311 and the second plate segment 312 are used to correspond to the middle of the battery cell. That is, the pressure plate 31 has a V-shaped structure as a whole and has good stability.

[0068] Based on the above embodiment, it is preferred that the pressing plate 31 corresponds to the lower side of the material box 200 when the turning platform 11 is in the second state.

[0069] In another embodiment, please refer to Figure 4 The pressure plate 31 is L-shaped, with the bend closer to the center of the battery cell, thus providing good support. Based on this embodiment, the pressure plate 31 preferably corresponds to the upper side of the material box 200 when the flip platform 11 is in the second state, thereby staggering the arrangement with other components.

[0070] Taking into account the limited depth of the material box 200, when arranging multiple battery cells of different numbers, the arranging may take a long time due to the small space. Therefore, in one embodiment, the battery cell aligning mechanism 100 also includes a compensation member 32 provided on the flip platform 11. The compensation member 32 is arranged to avoid the pressure plate 31. The compensation member 32 can be movably arranged horizontally and in the up and down directions, and is adapted to the shape of the material box 200, and is used to fit with the lower edge of the material box 200 so as to be able to contact the lower end of the battery cell.

[0071] Initially, the compensating member 32 should correspond to the side of the flipping platform 11 so as to avoid interference with the installation of the material box 200. When the flipping platform 11 is in the first state, the material box 200 is first fixed, and then the orientation of the compensating member 32 is adjusted so that it can correspond to the opening of the material box 200, and then the upper and lower parts are adjusted so that the pressure plate 31 can fit with the lower edge of the material box 200. Since the fulcrum of the battery cells is located at the bottom during the sorting action, the compensation member 32 can extend the length of the material box 200 as a support part, thereby providing sufficient space for the battery cells to be scattered and arranged.

[0072] It is understandable that when the material box 200 has a corner 210 , the compensation member 32 is configured to be V-shaped for adaptation.

[0073] The present invention does not limit the driving method of the compensation member 32 and the pressure plate 31. Figure 4 In one embodiment, the compensating member 32 and the pressing plate 31 can be located on different sides of the material holding box 200 and driven by their respective driving modules without interfering with each other's activities. Figure 2 In another embodiment, the supporting and pressing assembly 3 further includes a support 33 movably mounted horizontally to the flip platform 11. The support 33 is located on the side of the pushing portion 21 facing away from the flip platform 11. The compensating member 32 and the pressing plate 31 are disposed on the support 33 and arranged along the thickness direction of the flip platform 11. Both the compensating member 32 and the pressing plate 31 are movable in a direction toward or away from the flip platform 11. In this embodiment, the compensating member 32 and the pressing plate 31 can be driven up and down by separate cylinders, but can be driven to move synchronously by the support 33, facilitating a compact structure.

[0074] In order to enable the flip platform 11 to transition between the two states, in one embodiment, the supporting assembly 1 further includes a mounting base 12 and a rotating shaft 13. The rotating shaft 13 is rotatably mounted on the mounting base 12 along its extension direction, and the middle portion of the flip platform 11 is fixed to the rotating shaft 13. The rotating shaft 13 is driven by a drive motor to rotate, thereby causing the flip platform 11 to flip. Controlling the drive motor can precisely control the rotation angle of the flip platform 11. It will be understood that with this arrangement, when the flip platform 11 is in the first state, the corresponding drive motor and rotating shaft can be hidden between the flip platform 11 and the mounting base 12, facilitating a compact structural arrangement.

[0075] In other embodiments, the rotation of the flip platform 11 may also be achieved by cooperating with a cylinder and a connecting rod structure, and the present invention does not limit this.

[0076] The present invention does not limit the method of fixing the material box 200. In one embodiment, a contoured groove and a clamping assembly can be provided. In another embodiment, the supporting assembly 1 further includes a plurality of positioning structures 14 arranged at intervals. Each positioning structure 14 includes a fixing seat 141 and a pressing arm 142. The fixing seat 141 is provided on the flip platform 11 and is used to be provided on the side of the material box 200. The pressing arm 142 is movably mounted on the fixing seat 141 so as to be able to movably press against or release the material box 200, so that the material box 200 and the flip platform 11 are fixed to or separated from each other. Such a structure is simple. By rotating the pressing arm 142, the material box 200 can be avoided. By controlling the lifting and lowering of the pressing arm 142, the material box 200 can be pressed or released.

[0077] In this embodiment, there are two positioning structures 14 , and the two positioning structures 14 are arranged opposite to each other.

[0078] Furthermore, to reduce weight and enhance lightweight design, the end surface of the flip platform 11 is provided with multiple weight-reducing holes. The cell alignment mechanism 100 also includes a sensor, which is installed in one of the weight-reducing holes. The sensor can be single or multiple, and can be used to detect information such as the position of the material box 200 or the status of the cells within the box 200.

[0079] In the technical solution of the present invention, initially, the flipping platform 11 is set horizontally as a whole, and the material box 200 with multiple scattered battery cells is placed on the flipping platform 11 and fixed by the positioning structure 14. Then the pressure plate 31 and the compensation part 32 are driven to move to reach the corresponding position, and the flipping platform 11 is driven to flip 90°. At this time, the corner 210 of the material box 200 is set downward, and the pushing part 21 and the pressing part 23 are controlled to blow air while doing up and down reciprocating movements. This process is repeated until the battery cells are sorted. The flipping platform 11 is driven to flip and reset, and the neat battery cells and the material box 200 are taken away in turn through the external structure, or the material box 200 is taken away together with the battery cells to complete the sorting process.

[0080] The present invention also provides a battery cell packaging device, including the above-mentioned battery cell aligning mechanism 100. The battery cell packaging device includes all the technical features of the above-mentioned battery cell aligning mechanism 100, and therefore also has the technical effects brought by all the above-mentioned technical features, which will not be described one by one here.

[0081] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
