Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

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.

[0034] like Figure 1-5As shown, this utility model embodiment provides a battery cell flipping device, specifically including a vertical mounting frame 1, a lifting mechanism 2, a horizontal mounting frame 3, a horizontal flipping mechanism 4, and an adsorption assembly. The lifting mechanism 2 is mounted on the vertical mounting frame 1, and the horizontal flipping mechanism 4 is mounted on the horizontal mounting frame 3. The horizontal mounting frame 3 is mounted on the lifting end of the lifting mechanism 2, so that the lifting mechanism 2 can drive the entire horizontal mounting frame 3 to move vertically, raising or lowering the horizontal flipping mechanism 4. The horizontal flipping mechanism 4 is used to flip the battery cell 10. Specifically, the horizontal mounting frame 3 is provided with a flipping cavity 31 with upper and lower openings. The horizontal flipping mechanism 4 includes a flipping device 41, a flipping shaft 42, and a flipping plate 43. The flipping device 41 is mounted on the horizontal mounting frame 3, and the flipping shaft 42 is connected to the flipping device 41. The flipping shaft 42, with one end away from the flipping device 41, passes through the two side walls of the flipping cavity 31. The two ends of the flipping shaft 42 are rotatably mounted on the two side walls of the flipping cavity 31, so that the flipping device 41 can drive the flipping shaft 42 to rotate. The flipping plate 43 is horizontally set and connected to the flipping shaft 42 located in the flipping cavity 31. Furthermore, the flipping plate 43 has a horizontal flipping surface 431. The adsorption component is set at the flipping plate 43, and the adsorption end of the adsorption component is located at the horizontal flipping surface 431, which can adsorb the battery cell 10 onto the horizontal flipping surface 431. Thus, the flipping shaft 42 can drive the flipping plate 43 to rotate 180 degrees, and the battery cell 10 adsorbed on the horizontal flipping surface 431 also flips 180 degrees, thereby completing the flipping of the battery cell 10. The overall structure is simple and easy to operate.

[0035] The flip plate 43 is symmetrically arranged on the horizontal plane about the axis of the flip shaft 42. Therefore, the flip radius of the flip plate 43 when it rotates is the distance between the axis of the flip shaft 42 and the end of the flip plate 43. In the horizontal direction, only half the width of the flip plate 43 (battery cell 10) is needed. In the prior art, the flip shaft 42 drives the cantilever to flip, and its flip radius is the distance between the axis of the flip shaft 42 and the end of the cantilever. Since the end of the cantilever needs to be horizontally installed with the battery cell 10, the minimum horizontal radius is the width of the entire battery cell 10. Therefore, by directly connecting the flip plate 43 to the flip shaft 42 and making the flip plate 43 symmetrical about the axis of the flip shaft 42, the required rotation radius of the battery cell 10 on the flip plate 43 when it rotates will be greatly reduced. The space required for the battery cell 10 to move will be greatly reduced, and the installation space of the entire device will also be greatly reduced. Furthermore, with the rotation radius reduced, the acceleration and inertial force during rotation will be reduced, thereby reducing the possibility of structural vibration during acceleration and deceleration that could cause microcracks in the battery cell 10.

[0036] Specifically, the adsorption assembly includes two adsorption sub-assemblies 5, which are respectively located at both ends of the flip plate 43 and on both sides of the flip shaft 42, and are used to adsorb the two ends of the battery cell 10. Specifically, the adsorption sub-assembly 5 includes a first vent pipe 51 and suction cups 52. The first vent pipe 51 is parallel to the axis of the flip shaft 42 and is located at the end of the flip plate 43. Specifically, the first vent pipe 51 is connected to the lower side wall of the flip plate 43. Multiple suction cups 52 are provided and are evenly distributed along the first vent pipe 51 and connected to the first vent pipe 51. Air is supplied to the first vent pipe 51 through an external air source, and then adsorption is performed by the suction cups 52.

[0037] Preferably, both ends of the flip plate 43 are provided with multiple through grooves 432 for placing the suction cups 52, which can be used to protect the suction cups 52. Furthermore, the suction cups 52 are accordion-type suction cups 52, and the adsorption surface of the suction cups 52 is higher than the horizontal flip surface 431 (the side wall of the flip plate 43 away from the flip axis 42). Thus, the suction cups 52 can not only make close contact with the battery cell 10 and have better adsorption of the battery cell 10, but also the suction cups 52 can be hidden in the through grooves 432, so that the battery cell 10 is in close contact with the horizontal flip surface 431, thereby giving the bottom of the battery cell 10 support, increasing the support strength, and reducing the probability of breakage.

[0038] Specifically, the end of the rotating shaft 42 away from the rotating device 41 is provided with two ventilation holes. The inlet and outlet of the ventilation pipes are respectively located on the side wall of the rotating shaft 42 away from the rotating device 41 and on the outer peripheral side wall of the rotating shaft 42. The side wall of the end of the rotating shaft 42 is provided with two first external air pipe connectors 6, which are connected to the air inlets of the two ventilation holes. The side wall of the rotating shaft 42 located in the rotating cavity 31 is provided with two first internal air pipe connectors 7, which are connected to the air outlets of the two ventilation holes. The two first internal air pipe connectors 7 are located on both sides of the axis of the rotating shaft 42, and are respectively connected to the two first ventilation pipes 51 through air pipes. The through holes are cut out at the end of the rotating shaft 42 to serve as air passages. On the one hand, the air passages are simplified. Moreover, located at the central axis, each first ventilation pipe 51 is connected to the first internal air pipe connector 7 on the same side through air pipes. This avoids the situation where the air pipe connected to the first ventilation pipe 51 is twisted too much after rotating 180 degrees, which would cause damage to the air pipe after long-term use.

[0039] Specifically, a second vent pipe 8 is provided on the outer wall of the horizontal mounting frame 3 away from the tilting device 41. The outlet of the second vent pipe 8 faces the tilting shaft 42, and two second external air pipe connectors 9 are connected to the outlet. The two second external air pipe connectors 9 are connected to two first external air pipe connectors 6 respectively, and the distribution direction of the two second external air pipe connectors 9 is perpendicular to the distribution direction of the two first external air pipe connectors 6. Thus, during the 180-degree rotation of the tilting shaft 42, the air pipes connected between the second external air pipe connectors 9 and the first external air pipe connectors 6... The torsion angle changes by only 90 degrees. However, since the distribution directions of the two second external tracheal connectors 9 and the two first external tracheal connectors 6 are parallel, after the flip shaft 42 rotates 180 degrees, the torsion angle of the trachea connecting the second external tracheal connectors 9 and the first external tracheal connectors 6 changes by 180 degrees or even 360 degrees. This makes the distribution directions of the two second external tracheal connectors 9 and the two first external tracheal connectors 6 perpendicular, which can extend the service life of the trachea between them and improve the ventilation stability of the trachea.

[0040] Specifically, the horizontal mounting frame 3 includes a frame with a rectangular structure. A support plate 32 is connected between the two inner side walls of the frame parallel to the flipping shaft 42. The flipping device 41 is connected to the outer side wall of the frame near the vertical mounting frame 1. Its output shaft passes through the outer side wall of the frame. The two ends of the flipping shaft 42 are rotatably mounted on the support plate 32 and the side wall of the frame away from the vertical mounting frame 1, respectively. The support plate 32 and the frame form a flipping cavity 31. The flipping shaft 42 is located in the flipping cavity 31. The flipping device 41 can be a motor 21. The output shaft of the motor 21 is connected to the flipping shaft 42 through a coupling.

[0041] Specifically, in this embodiment, two flip plates 43 are provided, and the two flip plates 43 are symmetrically arranged in the vertical direction about the axis of the flip shaft 42, that is, the two flip plates 43 are arranged vertically and parallel to each other. Correspondingly, two adsorption components are provided, each connected to one of the two flip plates 43. Correspondingly, four first internal air pipe connectors 7 are provided, two on each side of the axis of the flip shaft 42, and the two connectors are respectively connected to the upper and lower first air pipes 51. Thus, the two flip plates 43 can adsorb two battery cells 10, thereby allowing the flipping device 41 to rotate the flip shaft 42 in both directions. When flipped 180 degrees, the battery cell 10 can be flipped continuously, accelerating the flipping efficiency. If only one flipping plate 43 is set, it is necessary to rotate 180 degrees forward to flip the battery cell 10 and change its direction to complete the flipping, and then flip it 180 degrees in the opposite direction to return it to its original position and continue to attract the battery cell 10. This is equivalent to the flipping shaft 42 rotating 180 degrees forward and backward to flip one battery cell 10. However, by setting two flipping plates 43, rotating 180 degrees forward and backward, two battery cells 10 can be flipped and placed, which accelerates the flipping efficiency of the battery cell 10 and allows for continuous flipping. Of course, in this embodiment, in order to facilitate the connection between the flipping plate 43 and the flipping shaft 42, a connecting block is provided on the outer wall of the flipping shaft 42, and the two flipping plates 43 are connected to the upper and lower horizontal side walls of the connecting block by bolts.

[0042] Specifically, multiple horizontal flipping mechanisms 4 can be set and evenly distributed side by side in the flipping cavity 31. In this embodiment, two horizontal flipping mechanisms 4 are set, and two flipping shafts 42 work at the same time. When the flipping shaft 42 is flipped 180 degrees, two battery cells 10 can be flipped and placed at one time.

[0043] Specifically, the lifting mechanism 2 includes a motor 21, a lead screw 22, and lead screw mounting blocks 23. The motor 21 is mounted on the vertical mounting frame 1 with its output shaft facing vertically upward. There are two lead screw mounting blocks 23, which are mounted on the vertical mounting frame 1 and spaced apart along the vertical direction. The two ends of the lead screw 22 are rotatably mounted on the two lead screw mounting blocks 23 respectively. The output shaft of the motor 21 is connected to the lead screw 22 via a coupling. The horizontal mounting frame 3 is connected to the nut on the lead screw 22. Thus, the motor 21 can drive the horizontal mounting frame 3 to move up and down as a whole through the lead screw 22, causing the horizontal tilting mechanism 4 on it to move up and down, thereby adjusting the tilting height of the horizontal tilting mechanism 4 to meet the user's needs. Specifically, a connecting plate 33 is connected to the side wall of the horizontal mounting frame 3 near the vertical mounting frame 1. The connecting plate 33 is vertically arranged, and a slide rail 24 is arranged on the side wall near the vertical mounting frame 1 along the vertical direction. A slider 25 is arranged on the vertical mounting frame 1. The slider 25 is slidably mounted on the slide rail 24. Through the cooperation of the slide rail 24 and the slider 25, the vertical lifting and lowering movement of the horizontal mounting frame 3 is further stabilized.
