Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cell production equipment, in particular to a correction and positioning device for a cell. Background Art

[0002] Solar cells are devices that convert sunlight into electrical energy. As the cleanest renewable resource, solar energy is increasingly being used in a wide range of applications. Silicon solar cells are a type of solar cell. Based on the advantages of silicon being non-toxic, cheap, and having large reserves in the earth's crust, most commercial solar cells are currently made from silicon wafers. The production of solar cells often involves multiple processes, such as loading and slicing, laser scribing, screen printing, and slicing.

[0003] In the prior art, battery cells are usually transported by conveyor belts. Since the entire production line is long, battery cells are prone to become skewed on the conveyor belt due to factors such as jitter or angle transmission during transportation. Therefore, a battery cell correction structure is an indispensable component during the circulation of battery cells. If the battery cells lack a correction structure during the circulation process, the positioning of the battery cells will be inaccurate, which will easily cause processing failure during the processing and increase the defective rate of battery cell production.

[0004] Specifically, the common alignment structures of battery cells are mostly in the form of single-side alignment, double-side alignment, three-side alignment or four-side alignment. Among them, the four-side alignment has the highest positioning accuracy for battery cells compared to single-side, double-side and three-side alignment. However, for the four-side alignment, the difficulty lies in the difficulty of achieving the synchronization of the four-side movement of the alignment mechanism. When the synchronization of the four-side movement cannot be guaranteed, not only can the accurate positioning of the battery cell not be achieved, but it will also directly lead to the problem of alignment failure.

[0005] Therefore, for the four-side alignment of the battery cell, it is necessary to optimize the design of the specific alignment mechanism to ensure the synchronization of the four-side movement, so as to achieve the use requirement of improving the precise positioning of the battery cell.

[0032] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0033] See also Figures 1 to 3 As shown, this embodiment provides a correction and positioning device for a battery cell, comprising: a support platform 1, and a substrate table 21, a correction and positioning mechanism and a driving mechanism arranged on the support platform 1.

[0034] Specifically, first, the support platform 1 has at least one platform surface 11 to form a loading area for the substrate stage 21 and the alignment positioning mechanism. In this regard, the substrate stage 21 is generally mounted on the platform surface 11 of the support platform 1, and is used to support the battery cell. Here, in order to adapt to the use requirements of the battery cell used in general, the substrate stage 21 can optionally adopt a rectangular structure.

[0035] It should be further explained that, in an optional implementation, the substrate stage 21 is mounted on the support platform 1 via at least four columns 3. Under this structure, a certain accommodation space is formed between the substrate stage 21 and the platform surface 11 of the support platform 1.

[0036] Next, the return positioning mechanism is explained, which includes at least four return positioning components arranged on the support platform 1 and adapted to correspond to the four side edges of the battery cell respectively. Each return positioning component includes at least a movable frame 51 and at least one positioning wheel 52 arranged on the movable frame 51 for contacting with one side edge of the battery cell; that is, the four return positioning components are respectively located on the four sides of the substrate stage 21. The movement of the movable frame 51 can drive the positioning wheel 52 to move synchronously.

[0037] The positioning wheel 52 is rotatably mounted on the movable frame 51, and the positioning wheel 52 is made of elastic material such as rubber. The positioning wheel 52 made of such material can reduce the wear on the side edge of the battery cell.

[0038] Based on the above situation, it is necessary to explain that the correction positioning mechanism used in this embodiment also includes four guide components that are arranged on the support platform 1 and match the four correction positioning components one by one. The guide components here are mainly used to accurately control the movement trajectory of the movable frame 51 to prevent it from deflecting.

[0039] In this regard, a detailed optional implementation is given as an example in conjunction with the attached drawings. Each guide assembly includes two slide rails 61 provided on the support platform 1, and a slide groove 62 formed on the movable frame 51 and suitable for slidingly cooperating with the slide rails 61. Regarding the slide rails 61 here, it is necessary to explain that the extension direction of the slide rails 61 of each guide assembly on the support platform 1 defines the movement direction of the movable frame 51, and the extension direction of the slide rails 61 of each guide assembly is perpendicular to the side end surface of the substrate stage 21 corresponding to the movable frame 51 that this guide assembly cooperates with. In this way, the relative approach and separation of the four alignment and positioning assemblies are achieved by the vertical movement of each movable frame 51 relative to the side end surface of the substrate stage 21.

[0040] Based on the above structure, it is necessary to explain that in order to prevent the movable frame 51 from unexpectedly moving too far when moving along the slide rail 61, the present embodiment also has the following design:

[0041] In the first case, a limit block 41 is provided on the slide rail 61 used by at least one guide assembly for limiting the range of motion of the movable frame 51 corresponding to the guide assembly on the slide rail 61. Here, the limit blocks 41 may be located on both sides of the corresponding movable frame 51 on the slide rail 61 used by each guide assembly.

[0042] In the second case, the support platform 1 is further provided with a limiting column 42 for limiting the motion range of at least one movable frame 51 on the slide rail 61. Here, a limiting column 42 can be designed on the support platform 1 and on both sides of the movable frame 51.

[0043] In the third case, for each guide assembly, a limit column 42 can be provided on the support platform 1, and a limit block 41 can be provided on the slide rail 61. And for each guide assembly, the limit column 42 and the limit block 41 are respectively located on both sides of the movable frame 51 corresponding to the guide assembly. The advantage of such a design is that the assembly space on the support platform 1 and the slide rail 61 is fully utilized, and the compactness of the overall return positioning device structure is further improved.

[0044] The above three optional implementations all meet the usage requirements of this embodiment and are not absolutely limited here.

[0045] Finally, the driving mechanism includes at least a turntable 8 suitable for rotating, and four transmission members 7 arranged one-to-one between the turntable 8 and the four movable frames 51; based on this structure, the turntable 8 is suitable for making the four return positioning components relatively close to and relatively far away by switching its forward and reverse running states. Of course, it can be understood that the driving mechanism also includes a power structure for driving the turntable 8 to rotate, and the power structure can be directly or indirectly connected to the motor 9, and the turntable 8 is driven to rotate through the design of the motor 9.

[0046] The transmission member 7 here can be a pull rod, and one end of the pull rod is rotatably connected to the turntable 8, and the other end of the pull rod is rotatably connected to the movable frame 51.

[0047] For the four correcting and positioning components in this embodiment, the same driving mechanism is used to realize the regulation of their operating states, so that the synchronization of the operating states of the four correcting and positioning components can be effectively guaranteed, thereby ensuring the reliable operation of the four correcting and positioning components. In this process, each correcting and positioning component can be configured with a limit block 41 and / or a limit column 42, or only one or two correcting and positioning components can be configured with a limit block 41 and / or a limit column 42, because the four correcting and positioning components move synchronously under the action of the same driving mechanism, and one of the correcting and positioning components is limited in movement due to the action of the limit block 41 and / or the limit column 42, and the remaining correcting and positioning components can no longer continue to move.

[0048] In addition, in order to reduce the size of the overall alignment and positioning mechanism for the battery cell and improve the compactness of the overall structure, the turntable 8 is disposed below the substrate stage 21 in this embodiment, that is, the turntable 8 is disposed in the accommodating space formed between the substrate stage 21 and the platform surface 11 of the support platform 1.

[0049] In summary, the specific usage and principle of the battery cell alignment device of this embodiment are as follows:

[0050] After the battery cell is placed on the substrate table 21, the motor 9 rotates forward (or reversely), and the turntable 8 also starts to work. The turntable 8 drives the four transmission members 7 connected to the turntable 8 to move synchronously. The movement of the transmission member 7 pulls the movable frame 51 to move on the slide rail 61, so that the movable frames 51 of the four return positioning components are relatively close. When the slider moves to the limit block 41 on the slide rail 61, or the movable frame 51 is stopped by the limit column 42, the positioning wheel 52 positions the four side edges of the battery cell to achieve the return positioning effect of the battery cell. When the return positioning of the battery cell is completed, the motor 9 reverses (or rotates forward), and the turntable 8, the transmission member 7 and the movable frame 51 move synchronously. At this time, the movable frames 51 of the four return positioning components are relatively far away, so that the positioning wheel 52 leaves the battery cell. In this regard, that is to say, in the process of returning and positioning the battery cell, it is only necessary to control the operating state of the motor 9, and no other redundant operation process is required, so the operation is convenient and efficient, and the accuracy is high.
