DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] In this application, the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "top", etc. are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0040] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0041] In addition, the terms "installed", "set", "provided with", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0043] The solar cell cells need to be laser treated during the secondary sintering. In the related art, a handling device is usually used to carry the cell from the transport device to the laser processing device. After the laser processing is completed, the cell also needs to be carried from the laser processing device to the transport device by the handling device so as to carry out the subsequent process. Since the existing handling device is usually suitable for the single-piece handling of a whole cell, and the cell is produced in the production process in addition to the whole cell production, it is also produced in a half-cell production method. When the handling device is carrying a half-cell cell, due to the limited adsorption area of ​​the existing cell handling device, only a single half-cell cell or a single whole cell can be carried during one handling process, which not only has low compatibility with different types of batteries, but also has low handling efficiency for half-cell cells. Moreover, due to the limited adsorption area of ​​the suction cup and the small adsorption position of the half-cell cell, the suction cup may not accurately position the half-cell cell when adsorbing the half-cell cell, resulting in the adsorption of the half-cell cell not being firm, which may cause it to fall or be placed inaccurately during transportation and placement.

[0044] Based on this, the present application discloses a battery cell handling device and a laser processing system, wherein the suction cup of the battery cell handling device is divided into at least three adsorption areas, and each adsorption area is correspondingly provided with an adsorption hole, thereby increasing the adsorption area of ​​the suction cup on the battery cell. At least three adsorption areas allow the suction cup to carry at least two and a half battery cells. Due to the increase in adsorption areas, the fault tolerance of the suction cup when adsorbing battery cells is increased, which can effectively prevent the battery cells from falling off when the suction cup adsorbs the battery cells. And by using the battery cell handling device of the present application, the suction cup is divided into at least three adsorption areas, so that when it is necessary to adsorb half a battery cell, one adsorption area can be used to adsorb a half battery cell, and when it is necessary to adsorb a whole battery cell, three adsorption areas can be used to adsorb the whole battery cell at the same time, that is, the types of battery cells that can be adsorbed by the suction cup are increased, which is conducive to improving the compatibility of the battery cell handling device.

[0045] In order to facilitate further understanding of the technical solution of the battery cell transport device disclosed in the present application, it will be described in conjunction with embodiments and drawings.

[0046] See also Figure 1 and Figure 2 In the first aspect, the present application discloses a battery cell handling device 100, comprising a bracket 1, a suction cup 2 and a driving structure 3. The suction cup 2 is mounted on the bracket 1, and has a suction surface 2a, which is divided into at least three suction areas 4. The three suction areas 4 are arranged in sequence along the battery cell handling direction X, and each suction area 4 is provided with a suction hole 2b for adsorbing the battery cell. The driving structure 3 is connected to the bracket 1, and the driving structure 3 is used to drive the bracket 1 to drive the suction cup 2 to move.

[0047] Among them, the driving structure 3 can be but not limited to a motor, hydraulic drive and other driving structures 3, and the bracket 1 can be but not limited to a mechanical arm, a metal frame and other structures, and this application does not make specific limitations here.

[0048] It should be noted that Figure 2 The direction indicated by X is the direction of transport of the battery cell.

[0049] Considering that a battery cell is usually a square battery cell, a half-cell battery cell is also usually a square battery cell. Based on this, the present application will be described by taking the battery cell that is half a cell and is square as an example.

[0050] Optionally, the suction cup 2 may be a square suction cup 2 having a length direction, a width direction and a thickness direction. When dividing the at least three suction areas 4, the division may be performed along the length direction, such as Figure 2As shown, the width direction of the battery cell can be the conveying direction of the battery cell. Of course, it is understandable that the number of regions divided by the suction cup 2 can also be different according to the size of the battery cell to be adsorbed. For example, if the size of the battery cell is large, the suction cup 2 can be divided into three regions. If the size of the battery cell is small, it can be divided into more than three regions, such as four, five or six regions, etc. This application does not make specific limitations here.

[0051] For example, when the suction cup 2 of the present application is used to absorb two half-cells, when the two half-cells 6 are transported to the cell handling device 100, the suction surface 2a of the suction cup 2 of the cell handling device 100 faces the two half-cells 6. When the adsorption area 4 is three adsorption areas 4 arranged in sequence, the adsorption area 4 in the middle does not absorb the half-cell 6, and the adsorption areas 4 on both sides of the middle adsorption area 4 can each absorb one half-cell 6, so that the two half-cells 6 are separated by the middle adsorption area 4 to avoid collision between the two half-cells 6 when being transported. When the adsorption area 4 is four or more than four adsorption areas 4, one half-cell 6 can be absorbed by at least two adsorption areas 4, so that the adsorption of the cell can be more reliable. It can be seen that the cell handling device 100 provided by the present application has good adaptability to the half-cell 6, which not only improves the handling efficiency of the half-cell 6 but also improves the protection effect of the cell when transporting the cell.

[0052] In addition, multiple adsorption areas 4 can cooperate with each other. For example, the fewer adsorption areas 4 there are, the smaller the battery cells that the suction cup 2 can adsorb, and the more adsorption areas 4 there are, the larger the battery cells that the suction cup 2 can adsorb, thereby achieving the adsorption of different types of battery cells, thereby improving the compatibility of the battery cell handling device 100.

[0053] In some embodiments, the adsorption hole 2b is connected to an air pipe (not shown) on a side away from the adsorption surface 2a to achieve ventilation or exhaust of the adsorption hole 2b. Exemplarily, there may be multiple air pipes, some of which may be suction pipes and some of which may be exhaust pipes, wherein the suction pipe can achieve adsorption of the battery cell, and the exhaust pipe can prevent the battery cell from adhering to the suction cup 2 and blow the battery cell off. Multiple air pipes may also have the functions of suction and blowing at the same time, and the air pipe may be suctioned or blown through the pump body so that the battery cell can be adsorbed or blown off by the adsorption hole 2b. It can be understood that the more air pipes adsorb the battery cell, the more firmly the battery cell will be adsorbed on the suction cup 2, and the coordination between the suction and exhaust of the air pipe is conducive to improving the flexibility of the adsorption effect of the suction cup 2 and the flexibility of the battery cell handling device 100.

[0054] See also Figure 2 and Figure 3In some embodiments, the suction cup 2 includes a first suction cup portion 21 and a second suction cup portion 22, at least one of the first suction cup portion 21 and the second suction cup portion 22 is connected to the bracket 1, and the second suction cup portion 22 is movably connected to the first suction cup portion 21, so that the second suction cup portion 22 can move relative to the first suction cup portion 21 along the first direction. The first suction cup portion 21 and the second suction cup portion 22 together form an adsorption surface 2a. In other words, the first suction cup portion 21 and the second suction cup portion 22 of the suction cup 2 are spliced, and the connection between the first suction cup portion 21 and the second suction cup portion 22 adopts a movable connection mode. The bracket 1 can be connected to the first suction cup portion 21 or the second suction cup portion 22, or the bracket 1 can be connected to both at the same time. Exemplarily, when the first suction cup portion 21 moves relative to the second suction cup portion 22, an adjustable interval is generated between the first suction cup portion 21 and the second suction cup portion 22, so that the total adsorption area of ​​the suction cup 2 can be adjusted without increasing the size of the suction cup 2 itself. In this way, the suction cup 2 can absorb battery cells of different sizes, thereby improving the compatibility with different types of battery cells.

[0055] The first direction intersects with the transport direction of the battery cell. Figure 2 As shown in , the direction Y is the first direction, that is, the width direction of the suction cup 2. Specifically, the first direction Y may be perpendicular to the conveying direction X of the battery sheet.

[0056] Please also see Figure 2-Figure 4 In some embodiments, the suction cup 2 further includes a sliding connection structure 23, the sliding connection structure 23 includes a slide groove portion 231 and a slider portion 232, the slide groove portion 231 extends along the first direction, one of the slide groove portion 231 and the slider portion 232 is provided on the first suction cup portion 21, and the other of the slide groove portion 231 and the slider portion 232 is provided on the second suction cup portion 22, and the slider portion 232 is slidably connected to the slide groove portion 231, so that the second suction cup portion 22 can slide relative to the first suction cup portion 21 along the first direction. Specifically, the first suction cup portion 21 and the second suction cup portion 22 are connected by the sliding connection structure 23, and the interval between the first suction cup portion 21 and the second suction cup portion 22 is adjusted by adjusting the distance that the slider portion 232 slides relative to the slide groove portion 231 in the first direction. By connecting the slide groove portion 231 with the slider portion 232, the suction cup 2 can be adjusted according to the actual production product during production, and the slidable connection between the slide groove portion 231 and the slider portion 232 is conducive to quick adjustment of the suction cup 2 and is more convenient.

[0057] Optionally, by setting a limiter 233 on the slider portion 232, the position of the slider portion 232 in the chute portion 231 can be limited, so that the two suction cups 2 are kept in a relatively spaced position. Exemplarily, a fastening screw is also provided at the connection between the chute portion 231 and the slider portion 232. When the interval between the first suction cup portion 21 and the second suction cup portion 22 is adjusted, the slider portion 232 and the chute portion 231 can be tightly connected by fastening the screw to limit the sliding of the slider portion 232 in the chute portion 231, thereby fixing the interval between the first suction cup portion 21 and the second suction cup portion 22. It can be understood that when the fastening screw is loosened, the chute portion 231 and the slider portion 232 can slide relative to each other. It can be seen that the fastening screw can adjust the connection state between the slider portion 232 and the chute portion 231, and can prevent the slider portion 232 and the chute portion 231 from sliding relative to each other when the device is working. Of course, in another example, a buckle can be used to replace the design of the fastening screw, and a groove for the buckle to be buckled into is opened in the slide groove portion 231. When the buckle on the slider portion 232 is pushed into the groove of the slide groove portion 231, the position of the slider portion 232 in the slide groove portion 231 is restricted.

[0058] See also Figure 3 In some embodiments, there are multiple sliding connection structures 23, and each sliding connection structure 23 is arranged at intervals along the transport direction of the battery cell. Considering the stability of the connection between the first suction cup part 21 and the second suction cup part 22, specifically, multiple sliding connection parts are arranged at intervals along the transport direction X of the battery cell at the connection between the first suction cup part 21 and the second suction cup part 22. In this way, the stability of the connection between the first suction cup part 21 and the second suction cup part 22 can be improved, and the sliding connection structures 23 arranged at intervals can also be arranged reasonably, reducing the number of sliding connection structures 23, and avoiding the overall volume of the suction cup 2 being too large.

[0059] See also Figure 3 In order to further increase the adsorption surface 2a of the suction cup 2, in some embodiments, there may be two second suction cup parts 22, and the two second suction cup parts 22 may be slidably connected to the two sides of the first suction cup part 21 along the first direction. And the connection between the two second suction cup parts 22 and the first suction cup part 21 adopts a sliding connection structure 23. In this way, the adsorption surface 2a of the suction cup 2 is increased, and more adsorption areas 4 can be set accordingly to achieve adsorption of different battery cells.

[0060] It is understandable that the number of the second suction cup parts 22 may also be three, four, etc., and those skilled in the art may configure them according to the needs to increase the adsorption surface 2a of the suction cup 2.

[0061] See also Figure 4In some embodiments, the suction cup 2 further includes a connection surface opposite to the suction surface 2a in the thickness direction of the suction cup 2, and the slider portion 232 is located on the connection surface. The side of the slider portion 232 facing the suction surface 2a is the lower surface, and the lower surface of the slider portion 232 does not protrude from the suction surface 2a. Considering the protection of the battery cell when the suction surface 2a adsorbs the battery cell, the slider portion 232 should be prevented from protruding from the suction surface 2a in the thickness direction of the suction cup 2, so as to prevent the slider portion 232 from causing bump damage to the battery cell when the suction cup 2 adsorbs the battery cell.

[0062] Considering that the battery cell may collide with the suction cup 2 when it is sucked up by the suction cup 2, in other embodiments, a buffer portion 24 is provided on the suction surface 2a, and the buffer portion 24 is provided with an opening 24a to avoid the suction hole 2b. The buffer portion 24 buffers the battery cell to avoid direct hard contact between the battery cell and the suction cup 2, which is conducive to preventing the battery cell from being damaged by collision with the suction cup 2.

[0063] It is understandable that the hole 24 a is opened on the buffer portion 24 to avoid the adsorption hole 2 b so that the adsorption hole 2 b has a good adsorption effect on the battery cell.

[0064] In order to prevent the slider portion 232 from protruding beyond the buffer portion 24 and causing collision to the battery cell, the lower surface of the slider portion 232 does not protrude beyond the lower surface of the buffer portion 24 when viewed from the thickness direction of the suction cup 2 .

[0065] Optionally, the buffer portion 24 may be made of materials such as sponge and rubber, which is not specifically limited in the present application.

[0066] In some embodiments, the battery cell transport device 100 further includes a rotating structure 5, which is disposed at the connection between the bracket 1 and the suction cup 2, and the rotating structure 5 is used to rotate the suction cup 2 to adjust the angle of the suction cup 2 relative to the transport direction of the battery cell. It is understandable that when different battery cells are produced and placed on the transport device for transportation, the orientation of the battery cell may deviate from the transport direction of the battery cell set by the transport device. In addition, the subsequent laser processing of the battery cell has high requirements for the positioning of the battery cell. Therefore, when the battery cell is adsorbed by the suction cup 2, the rotating structure 5 can be rotated to adjust the angle of the suction cup 2 relative to the transport direction of the battery cell, thereby adjusting the orientation of the battery cell, so that the battery cell suction cup 2 can be better positioned when it is transported to the laser processing device 300, which is beneficial to improve the accuracy of laser processing.

[0067] Optionally, the rotating structure 5 may be, but is not limited to, a rotating shaft, a rotating disk, etc., and this application does not make any specific limitation here.

[0068] Second, see Figure 5The present application discloses a laser processing system, comprising: a first transport device 200, a cell transport device 100 as described in the first aspect, and a laser processing device 300. The first transport device 200 is used to transport cells, the cell transport device 100 is used to transport cells transported by the first transport device 200, and the laser processing device 300 is used to perform laser processing on cells transported by the cell transport device 100.

[0069] By using the cell handling device 100 provided in the first aspect of the present application, the laser processing system disclosed in the present application can improve the handling efficiency of the half-cell cell 6 and can effectively improve the efficiency of the laser processing of the half-cell cell 6 .

[0070] It is understandable that the first transportation device 200 can realize the loading of battery cells to the laser processing device 300 together with the battery cell handling device 100, so as to facilitate the laser processing device 300 to complete the laser processing of the battery cells.

[0071] Furthermore, considering how to unload the battery cells after the laser processing device 300 completes the laser processing, in some embodiments, there are two battery cell transport devices 100, and the battery cell laser processing system also includes a second transport device 400. Among the two battery cell transport devices 100, one battery cell transport device 100 is arranged between the first transport device 200 and the laser processing device 300, and is used to transport the battery cells transported by the first transport device 200 to the laser processing device 300, and the other battery cell transport device 100 is arranged between the laser processing device 300 and the second transport device 400, and is used to transport the battery cells after laser processing to the second transport device 400. In this way, the unloading of the battery cells after laser processing can be completed through the additional battery cell transport device 100 and the second transport device 400, and the fully automatic laser processing production of the battery cells can be realized.

[0072] In a third aspect, in order to be compatible with laser processing of half-cell 6, the present application discloses a laser processing device 300. The specific solution of the laser processing device 300 will be described below in conjunction with the accompanying drawings and embodiments.

[0073] See also Figure 6The laser processing device 300 includes a placement table 310, a laser emitter 320 and a probe structure 330. The placement table 310 has a table 311 for placing the battery cell. The laser emitter 320 is arranged above the placement table 310, and the laser emitter 320 is configured to emit a laser toward the table 311 of the placement table 310 to perform laser processing on the battery cell. The probe structure 330 is arranged on the table 311 of the placement table 310, and the probe structure 330 includes a probe bracket 331 and two probe groups 332 arranged on the probe bracket 331. The two probe groups 332 are arranged at intervals, and the two probe groups 332 are respectively used to abut against the battery cell on the table 311 to achieve electrical conduction of the battery cell.

[0074] Since the half-cell 6 is transported to the table 311 of the placement table 310, it is two half-cells 6, and the two half-cells 6 are also placed at a distance. In order to be compatible with the laser processing of the half-cell 6, the probe structure 330 uses two probe groups 332 to electrically connect the two half-cells 6. In this way, it can be avoided that due to the use of one probe group 332 to electrically connect the two half-cells 6, some probes in the probe group 332 pass through the gap between the two half-cells 6 and contact the table 311, thereby causing the two sides of the cell to be electrically connected, and effectively avoid damaging the passivation performance of the cell.

[0075] It is understandable that the two probe groups 332 can also abut against the entire battery cell to achieve electrical conduction of the entire battery cell.

[0076] The above is a detailed introduction to the battery cell handling device and battery cell laser processing system disclosed in the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the battery cell handling device and battery cell laser processing system of the present application and their core ideas; at the same time, for general technical personnel in this field, according to the ideas of the present application, there will be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present application.
