[0037] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] The edge covering device 100 according to the embodiments of the present application will be described below with reference to the drawings.

[0039] As shown in Figure 1 The edge covering device 100 according to the embodiments of the present application comprises a supporting table 10, an edge covering mechanism 20, a blanking mechanism 30 and an ion fan 40.

[0040] The support table 10 is adapted to carry the battery piece 80, and the support table 10 is rotatable or movable to drive the battery piece 80 to move between the edge covering station 10a and the discharging station 10b. The edge covering mechanism 20 covers the edge of the battery piece 80 at the edge covering station 10a. The discharging mechanism 30 moves the battery piece 80 from the discharging station 10b to the discharging station 10c. The ion fan 40 is directed towards the support table 10, or the ion fan 40 is directed towards the discharging mechanism 30, or the ion fan 40 is directed towards both the support table 10 and the discharging mechanism 30.

[0041] It can be understood that, during the process of covering the edge of the battery piece 80 by the edge covering device 100, the edge covering mechanism 20 covers the edge of the battery piece 80 at the edge covering station 10a. After the covering of the edge of the battery piece 80 is completed, the support table 10 is rotated or moved to move the battery piece 80 to the discharging station 10b. The discharging mechanism 30 moves the battery piece 80 located at the discharging station 10b to the discharging station 10c. During the above process of covering the edge of the battery piece 80, the battery piece 80 needs to be moved at multiple positions. For example, the battery piece 80 is moved and placed on the support table 10, which can be conveyed by the conveying belt 61. For another example, the discharging mechanism 30 moves the battery piece 80 to move away from the support table 10. For yet another example, the discharging mechanism 30 moves the battery piece 80 to the discharging station 10c.

[0042] The battery piece 80 is electrostatically charged during the process of being placed on the support table 10, or the battery piece 80 is rubbed against the structure of the edge covering device 100 during the above moving process, which causes the accumulation of static electricity on the battery piece 80. Under the action of static electricity adsorption, the battery piece 80 is easily adsorbed to the support table 10 or the discharging mechanism 30. During the process of covering the edge of the battery piece 80 by the edge covering device 100, the relative position between the battery piece 80 and the structure of the edge covering device 100 is easily deviated, or the battery piece 80 cannot automatically fall off from the discharging mechanism 30 under the action of gravity.

[0043] For example, when the discharging mechanism 30 moves the battery piece 80 to move away from the support table 10, the battery piece 80 is separated from the support table 10 and is easily electrostatically charged. Due to the static electricity adsorption between the battery piece 80 and the support table 10, the movement of the battery piece 80 by the discharging mechanism 30 is resisted, the contact position between the battery piece 80 and the discharging mechanism 30 is changed, the discharging mechanism 30 contacts the edge covering glue of the battery piece 80, and the edge covering glue remaining on the discharging mechanism 30 easily contacts the surface of the next battery piece 80, which causes the adhesion of the glue on the surface of the next battery piece 80 or causes the damage of the surface of the battery piece 80. After the battery piece 80 moves away from the support table 10, the static electricity accumulated on the battery piece 80 and the support table 10 is transferred to the battery piece 80 and the discharging mechanism 30, and the static electricity adsorption also resists the discharging of the battery piece 80 during the subsequent discharging process.

[0044] It can be understood that the ion fan 40 can generate a large amount of airflow with positive and negative charges, which can neutralize the static electricity on the support table 10 or the material feeding mechanism 30, thereby eliminating the static electricity on the battery piece 80 and reducing or avoiding the static adsorption between the battery piece 80 and the structure of the edge covering device 100.

[0045] Therefore, when the wind direction of the ion fan 40 is towards the support table 10, the static electricity accumulated on the support table 10 and the battery piece 80 located on the support table 10 can be eliminated. When the wind direction of the ion fan 40 is towards the material feeding mechanism 30, the static electricity accumulated on the material feeding mechanism 30 and the battery piece 80 on the material feeding mechanism 30 can be eliminated.

[0046] The edge covering device 100 of the present application can reduce or avoid the accumulation of static electricity on the battery piece 80, the support table 10 and the material feeding mechanism 30 by setting the ion fan 40, thereby reducing or avoiding the influence of static adsorption on the process of moving the battery piece 80, reducing or avoiding the deviation of the contact position of the battery piece 80 and different structures of the edge covering device 100 caused by static adsorption, and improving the edge covering effect of the battery piece 80.

[0047] In the present application, the type of the ion fan 40 is not limited. For example, the ion fan 40 includes an ion fan and an ion air knife, and the edge covering device 100 selects to set the ion fan or the ion air knife according to the size and shape of the installation space of the ion fan 40. For example, the support table 10 is correspondingly provided with an ion fan, and the material feeding mechanism 30 is correspondingly provided with an ion air knife (not shown in the figure).

[0048] It should be noted that the support table 10 can be configured to be rotatable, movable or both rotatable and movable. Figure 1 In the example, the support table 10 is configured to be rotatable, and the edge covering station 10a and the material feeding station 10b are arranged around the rotation axis of the workbench.

[0049] Preferably, the support table 10 is configured to be rotatable, and the upper surface of the support table 10 is configured to be circular, and the support table 10 is provided with four groups of battery piece 80 placing positions, which are arranged equidistantly along the circumference on the upper surface of the support table 10. The feeding station 10d, the edge covering station 10a and the material feeding station 10b are arranged in sequence along the circumference on the support table 10, and when the support table 10 is rotated by 90 degrees, the battery piece 80 located in the feeding station 10d moves to the edge covering station 10a, and the battery piece 80 located in the edge covering station 10a moves to the material feeding station 10b.

[0050] Therefore, the support table 10 can simultaneously carry the battery cells 80 at the loading station 10d, the edge wrapping station 10a, and the unloading station 10b, that is, the battery cells 80 are loaded at the loading station 10d, the edge wrapping station 10a, and the battery cells 80 are unloaded at the unloading station 10b, thereby improving the efficiency of edge wrapping of the battery cells 80.

[0051] In some embodiments, as Figure 1 As shown, the support platform 10 is further provided with a loading station 10d, and the hemming device 100 is further provided with a loading mechanism 60. The loading mechanism 60 includes a conveyor belt 61 and a loading suction cup 62. The loading suction cup 62 is movable and is used to move the battery cell 80 on the conveyor belt 61 to the loading station 10d. The wind direction of the ion blower 40 is also toward the loading mechanism 60, thereby reducing the accumulation of static electricity between the loading suction cup 62 and the battery cell 80.

[0052] In this application, the driving member 70 for controlling the movement of the loading suction cup 62 is not limited. Figure 1 In the embodiment, the loading suction cup 62 is connected to the slide rail, and a motor is used to drive the loading suction cup 62 to move along the slide rail.

[0053] Preferably, the loading suction cup 62 is configured to be movable in the vertical direction so that the loading suction cup 62 can absorb the battery cell 80 in the vertical direction and drive the battery cell 80 to leave the conveyor belt 61 in the vertical direction. After the battery cell 80 leaves the conveyor belt 61, the loading suction cup 62 moves to the loading station 10d and descends, and the loading suction cup 62 stops adsorption, so that the loading suction cup 62 and the battery cell 80 are disengaged, so that the battery cell 80 is placed at the loading station 10d of the support table 10. In the process of moving the battery cell 80, the battery cell 80 and the support table 10, and the battery cell 80 and the loading suction cup 62 are only adsorbed or disengaged in the vertical direction, which can reduce the friction between the battery cell 80 and the support table 10 or the loading mechanism 60, thereby reducing the static electricity generated on the battery cell 80.

[0054] Preferably, the loading suction cup 62 is a Bernoulli suction cup, which will not leave obvious marks on the surface of the battery cell 80 during operation and can effectively protect the surface of the battery cell 80 .

[0055] In some embodiments, as Figure 1 As shown, the unloading mechanism 30 includes a guide rail 31, a wafer carrier 32, and a material transfer mechanism 33. The first end of the guide rail 31 is adjacent to the unloading station 10b, and the second end extends to the unloading station 10c. The wafer carrier 32 is movable along the guide rail 31, and the material transfer mechanism 33 transfers the battery cell 80 located at the unloading station 10b onto the wafer carrier 32. The ion blower 40 directs the wind toward the wafer carrier 32, the material transfer mechanism 33, or both.

[0056] It can be understood that when the discharging mechanism 30 moves the battery piece 80 from the discharging station 10b to the discharging station 10c, the carrier table 32 stops at the first end of the guide rail 31, the moving mechanism 33 moves the battery piece 80 located in the discharging station 10b to the carrier table 32, and after the battery piece 80 is located on the carrier table 32, the carrier table 32 moves along the guide rail 31 to the second end, that is, the battery piece 80 moves to the discharging station 10c. In the above process, the static electricity accumulated on the moving mechanism 33 and the battery piece 80 is transferred to the battery piece 80 and the carrier table 32.

[0057] Therefore, by setting the direction of the ion fan 40 to be towards the carrier table 32 or the moving mechanism 33, or simultaneously towards the carrier table 32 and the moving mechanism 33, the accumulation of static electricity on the battery piece 80, the carrier table 32 and the moving mechanism 33 can be reduced or avoided, and during the moving of the battery piece 80, the battery piece 80 is relatively stationary with the carrier table 32, and the static electricity generated by the friction between the battery piece 80 and the carrier table 32 can be reduced or avoided.

[0058] In this application, the driving part 70 for controlling the movement of the carrier table 32 along the guide rail 31 is not limited. For example, in the Figure 1 , a motor is used to drive the movement of the carrier table 32. For another example, a pneumatic cylinder is used to drive the movement of the carrier table 32.

[0059] Further, as shown in Figure 2 , the carrier table 32 is provided with a carrier area 32a, and the carrier table 32 is provided with a avoiding gap 323 in the carrier area 32a, and the carrier table 32 is provided with a suction hole 322 on the upper surface of the carrier area 32a.

[0060] Therefore, the setting of the avoiding gap 323 can reduce the contact area between the carrier table 32 and the battery piece 80, thereby further reducing the static electricity generated between the carrier table 32 and the battery piece 80.

[0061] It can be understood that due to the reduction of the contact area, it is easy to cause the stability of the carrier table 32 to the battery piece 80 to be reduced. Therefore, by setting the suction hole 322, the position stability of the battery piece 80 on the carrier table 32 can be improved, the relative movement between the carrier table 32 and the battery piece 80 is reduced, and the static electricity generated by the friction is further reduced. Therefore, while reducing the static electricity generated between the carrier table 32 and the battery piece 80, the stable carrying of the carrier table 32 to the battery piece 80 can be maintained.

[0062] Preferably, a plurality of carrier areas 32a are provided on the carrier table 32, and each carrier area 32a carries one battery piece 80. Therefore, the carrier table 32 can simultaneously move a plurality of battery pieces 80, thereby improving the moving efficiency of the battery pieces 80. For example, in the Figure 2 example, two carrier areas 32a are provided on the carrier table 32, which can carry two battery pieces 80.

[0063] Further, as shown in Figure 2 The slide plate 32 includes a plurality of slide rods 321 arranged at intervals in the slide plate area 32a, the upper surface of the slide rod 321 is provided with an adsorption hole 322, and the slide rod 321 is provided with a gap 323. Thus, the slide plate 32 bears the battery sheet 80 through the slide rod 321, and the slide rod 321 is arranged at intervals to increase the area of the slide plate area 32a, that is, to increase the support area of the slide plate 32 to the battery sheet 80, and to improve the bearing stability of the slide plate 32 to the battery sheet 80.

[0064] At the same time, the area of the upper surface of the slide rod 321 is small, so the contact area with the battery sheet 80 is small, and the adsorption hole 322 can reduce the friction caused by the relative movement of the battery sheet 80 and the slide rod 321, thereby reducing the static electricity generated between the battery sheet 80 and the slide rod 321.

[0065] In some embodiments, the material moving mechanism 33 includes a material moving suction cup, which is movable in the vertical direction, and is movable between the discharging station 10b and the first end of the guide rail 31.

[0066] Thus, by arranging the material moving suction cup to be movable in the vertical direction, the material moving suction cup can adsorb the battery sheet 80 in the vertical direction and drive the battery sheet 80 to move away from the support table 10. When the battery sheet 80 moves away from the support table 10, the material moving suction cup moves to the first end of the guide rail 31 and descends, stops adsorbing, and separates from the battery sheet 80, so that the battery sheet 80 is placed on the slide plate 32 at the first end of the guide rail 31.

[0067] In the above process of moving the battery sheet 80, the battery sheet 80 contacts or separates from the support table 10, the material moving suction cup, and the slide plate 32 in the vertical direction, thereby reducing the friction between the battery sheet 80 and the support table 10 or the slide plate 32, and further reducing the static electricity generated on the battery sheet 80.

[0068] In this application, the driving member 70 for controlling the movement of the material moving suction cup is not limited, for example, in Figure 1 , the material moving suction cup is connected to the sliding rail, and a motor is used to drive the material moving suction cup to move along the sliding rail.

[0069] Preferably, the material moving suction cup is a Bernoulli suction cup, which will not leave obvious marks on the surface of the battery sheet 80 when working, and can effectively protect the surface of the battery sheet 80.

[0070] In some embodiments, as shown in Figure 1 , Figures 3-5As shown, the edge covering device 100 further comprises a storage mechanism 50, which is arranged at the discharging station 10c and has a storage position 51, wherein the discharging mechanism 30 moves the battery piece 80 along the first direction, and the storage mechanism 50 has an opening in the storage position 51 towards the first direction, and the battery piece 80 enters the storage position 51 from the opening, and the discharging mechanism 30 is disengaged from the battery piece 80 along the vertical direction after the battery piece 80 enters the storage position 51.

[0071] It can be understood that, after the discharging mechanism 30 moves the battery piece 80 to the discharging station 10c, the battery piece 80 is located in the storage position 51, and at this time, the discharging mechanism 30 is disengaged from the battery piece 80 along the vertical direction, so that the battery piece 80 is supported in the storage position 51, and the discharging mechanism 30 exits the storage position 51 along the first direction from the outlet, so as to achieve the storage of the battery piece 80 in the storage mechanism 50.

[0072] Therefore, by arranging the discharging station 10c in the storage position 51, when the battery piece 80 moves to the discharging station 10c, it can reach the storage position 51, and only by disengaging the discharging mechanism 30 from the battery piece 80 along the vertical direction, the battery piece 80 can be placed in the storage position 51. At the same time, the battery piece 80 can be supported in the storage position 51 along the vertical direction, so as to reduce or avoid the generation of static electricity due to the friction between the battery piece 80 and the discharging mechanism 30 and between the battery piece 80 and the storage mechanism 50.

[0073] Preferably, the first direction is arranged in the horizontal direction.

[0074] Preferably, the storage mechanism 50 adopts an iron frame, which can be moved as a whole into an oven for baking the edge covering glue on the battery piece 80 in a subsequent process, without the need to move the battery piece 80 out of the storage mechanism 50, thereby reducing the movement of the battery piece 80. By arranging a plurality of storage positions 51 in the storage mechanism 50, a plurality of battery pieces 80 can be moved and baked at the same time, thereby improving the efficiency of moving and baking the battery pieces 80.

[0075] Preferably, when the discharging mechanism 30 adopts a carrier table 32 to move the battery piece 80, and the carrier table 32 has a plurality of carrier areas 32a along the horizontal direction, each carrier table 32 supports one battery piece 80, and the storage mechanism 50 has a plurality of storage positions 51 arranged along the horizontal direction, and when the carrier table 32 is located at the discharging station 10c, the carrier area 32a corresponds to the storage position 51 one by one. Therefore, one carrier table 32 can simultaneously send a plurality of battery pieces 80 into the storage position 51, thereby improving the efficiency of moving the battery pieces 80 to the storage mechanism 50.

[0076] Further, as shown in FIG. 1, the edge covering device 100 further comprises a conveying mechanism 20, which is arranged at the conveying station 10b and has a conveying position 21, wherein the conveying mechanism 20 moves the battery piece 80 along the second direction, and the conveying position 21 has an opening towards the second direction, and the battery piece 80 enters the conveying position 21 from the opening, and the conveying mechanism 20 is disengaged from the battery piece 80 along the vertical direction after the battery piece 80 enters the conveying position 21. Figure 4As shown, the storage mechanism 50 is provided with a wafer boss 52 at the storage position 51, and the wafer boss 52 is adapted to support the battery sheet 80. In this way, by supporting the battery sheet 80 through the wafer boss 52, the contact area between the battery sheet 80 and the storage mechanism 50 can be reduced, so as to reduce or avoid the contact between the edge covering adhesive of the battery sheet 80 and the storage mechanism 50, and the static electricity generated between the battery sheet 80 and the wafer boss 52 can be reduced.

[0077] At the same time, the contact position between the wafer boss 52 and the battery sheet 80 can avoid the edge of the battery sheet 80, so as to further reduce or avoid the contact between the edge covering adhesive of the battery sheet 80 and the storage mechanism 50 and the remaining at the storage position 51.

[0078] Further, the battery sheet 80 is carried above the discharging mechanism 30, the storage mechanism 50 includes a plurality of storage positions 51 arranged in the vertical direction, and the storage mechanism 50 is provided with a avoiding space 53 at the storage position 51 to avoid the discharging mechanism 30 in the vertical direction. Wherein, the storage mechanism 50 is movable in the vertical direction.

[0079] It can be understood that, in the process of placing the battery sheet 80 at the storage position 51, the discharging mechanism 30 is partially located in the storage position 51, so as to provide the avoiding space 53, which can provide the moving space of the discharging mechanism 30 in the first direction and the vertical direction in the storage mechanism 50, so as to ensure that the discharging mechanism 30 can be partially moved into the storage position 51. When the battery sheet 80 moves to the storage position 51 with the discharging mechanism 30, the storage mechanism 50 is raised in the vertical direction, so that the wafer boss 52 abuts against the battery sheet 80 and drives the battery sheet 80 to rise synchronously, until the battery sheet 80 is separated from the discharging mechanism 30 in the vertical direction. When the battery sheet 80 is separated from the discharging mechanism 30, the discharging mechanism 30 leaves the storage position 51, so as to realize the transfer of the battery sheet 80 to the storage position 51.

[0080] In addition, when the battery sheet 80 moves to the storage position 51 with the discharging mechanism 30, it is necessary to ensure that the wafer boss 52 stably abuts against the battery sheet 80, and the battery sheet 80 can be stably separated from the discharging mechanism 30, and the storage mechanism 50 is raised at a first speed. When all the storage positions 51 of the storage mechanism 50 store the battery sheet 80, the battery sheet 80 in the storage position 51 only contacts the storage mechanism 50, and the battery sheet 80 moves synchronously with the storage mechanism 50, and the storage mechanism 50 is raised or lowered at a second speed.

[0081] In this way, the first speed is set to be less than the second speed, that is, after the battery sheet 80 enters the storage position 51 from the opening, the storage mechanism 50 is raised at a smaller speed, which can reduce or avoid the vibration or shaking of the battery sheet 80 when it is separated from the discharging mechanism 30 in the vertical direction, so as to improve the stability of the battery sheet 80 in the storage position 51 and the structural stability of the battery sheet 80 itself.

[0082] At the same time, it can also avoid or reduce the battery cell 80 from contacting another battery cell 80 adjacent in the vertical direction due to shaking, and avoid or reduce the battery cell 80 from contacting the detached unloading mechanism 30 again due to shaking, that is, avoid or reduce the surface of the unloading mechanism 30 or another battery cell 80 from being stained with edge glue.

[0083] Preferably, when the battery cells 80 enter the storage positions 51 from the opening, the storage mechanism 50 rises at a speed of 100 mm / s. When all storage positions 51 of the storage mechanism 50 contain battery cells 80, or when all storage positions 51 of the storage mechanism 50 are empty of battery cells 80, the storage mechanism 50 moves vertically at a speed of 400 mm / s.

[0084] In some specific embodiments, Figure 1 As shown, when the ion blower 40 is directed toward the support platform 10, the ion blower 40 is located on the side of the support platform 10 away from the hemming station 10a. When the ion blower 40 is directed toward the blanking mechanism 30, the ion blower 40 is located vertically above the blanking mechanism 30.

[0085] It is understandable that when the airflow blown by the ion blower 40 flows to the battery cell 80, the airflow generates thrust on the battery cell 80. The support platform 10 and the unloading mechanism 30 both support or adsorb the battery cell 80 in the vertical direction.

[0086] Therefore, the ion blower 40 is arranged on the side of the support platform 10 away from the edging station 10a, and the airflow blown out by the ion blower 40 flows directly to the side of the support platform 10 away from the edging station 10a. The distance from the ion blower 40 to the edging station 10a is relatively far, which can reduce or avoid the battery cell 80 located at the edging station 10a being pushed by the airflow, and reduce or avoid the relative movement of the battery cell 80 and the support platform 10 caused by the airflow.

[0087] At the same time, the ion blower 40 is arranged vertically above the unloading mechanism 30, so that the airflow can flow in the vertical direction to the unloading mechanism 30 and the battery cell 80. The thrust of the airflow on the battery cell 80 is in the vertical direction, which can reduce or avoid the horizontal movement of the battery cell 80 relative to the unloading mechanism 30 under the action of the airflow, thereby maintaining the position stability of the battery cell 80 in the unloading mechanism 30.

[0088] In some specific embodiments, the support table 10 or the unloading mechanism 30 is grounded, or both the support table 10 and the unloading mechanism 30 are grounded. Thus, through the grounding process, the static electricity accumulated on the support table 10 and the unloading mechanism 30 can be neutralized, thereby reducing the static electricity accumulation between the battery cell 80 and the support table 10, or between the battery cell 80 and the unloading mechanism 30.

[0089] In this application, there is no limitation on the mechanism by which the hemming mechanism 20 hems the battery cell 80. For example,Figure 1 When the battery piece 80 is located at the edge covering station 10a, the rolling brush 21 moving along the circumferential direction of the battery piece 80 is arranged to realize the edge covering of the battery piece 80.

[0090] Other configurations and operations of the edge covering device 100 according to the embodiments of the present application are known to those skilled in the art, and will not be described in detail herein.
