As shown in fig. 4 and 5, in an embodiment, the second transferring device 3 includes a clamping assembly 6, and the clamping assembly 6 is used to clamp the battery assembly 91 transferred on the transferring rack, so as to prevent the battery assembly 91 from being displaced or falling during the overturning process. The clamping assembly 6 is provided on the rotating bracket 42 and is rotatable with the rotating bracket 42. The clamp assembly 6 includes a clamp driving device 61 and a clamp claw 62, the clamp claw 62 being located at the outer periphery of the transfer bracket 31 and protruding toward the middle of the transfer bracket 31. The clamping driving device 61 is connected to the clamping jaw 62, and the clamping driving device 61 is used for driving the clamping jaw 62 to move close to the conveying bracket 31 and clamp the object conveyed on the conveying bracket.
The clamping claw 62 may have a rod shape, a sheet shape, or the like, and the clamping claw 62 may be moved toward and away from the conveying bracket 31 to clamp objects such as the first tray 71 and the second tray 72 conveyed on the conveying bracket 31.

In operation, the first tray 71 or the second tray 72 transported on the transporting bracket 31 can be positioned by the positioning pin 33, then the first tray 71 or the second tray 72 is clamped by the clamping component 6, and finally the first transporting device 2 and the second transporting device 3 are driven by the rotating device 4 to turn over the first tray 71 or the second tray 72 and the battery component 91 thereon.
In the above technical solution, the first conveying device 2 and the second conveying device 3 respectively include the clamping assembly 6, the clamping assembly 6 includes the clamping driving device 61 and the clamping claw 62, and the first tray 71 or the second tray 72 conveyed on the conveying support and the battery assembly 91 thereon can be clamped by the clamping driving device 61 and the clamping claw 62, so that the battery assembly 91 is better stable when being overturned, and the battery monomer is prevented from falling. And the entire battery assembly can be fixed by clamping the battery case 92 or the second tray 72 by the clamping claws 62, so that the battery assembly 91 can be prevented from being damaged by clamping.
As shown in fig. 2 and 3, the battery pack tilting device further includes a battery pack transmission line including a feeding transmission line 81 and a discharging transmission line 82, and the first and second transmission devices 2 and 3 connect the feeding transmission line 81 and the discharging transmission line 82. Wherein a feed transfer line 81 is located upstream of the first transfer device 2 and the second transfer device 3, the feed transfer line 81 being for transferring the first tray 71 and the second tray 72 (the second tray 72 having the battery pack 91 rotated thereon) to the first transfer device 2 and the second transfer device 3. The discharging transmission line 82 is located downstream of the first transmission device 2 and the second transmission device 3, and after the inverted battery assembly 91 and the battery box 92 are turned over by the battery assembly turning device, they are output from the first transmission device 2 or the second transmission device 3, and are output to the subsequent processing station by the discharging transmission line 82. The feeding transmission line 81 and the discharging transmission line 82 may be drum-type transmission devices, transmission belt-type transmission devices, etc., and the feeding transmission line 81 and the discharging transmission line 82 may be the same transmission device or different transmission devices.
In some embodiments, the feeding transfer line 81 needs to transfer the first tray 71 and the second tray 72 rotating the battery pack 91 to be flipped, so the feeding transfer line 81 may be provided with two transfer branches, one for transferring the first tray 71 and the other for transferring the battery pack 91 and the second tray 72, which meet at the first transfer device 2.
In the above technical solution, the first transmission device 2 and the second transmission device 3 are connected with the feeding transmission line 81 and the discharging transmission line 82, so that the battery assembly can be directly transmitted to the first transmission device 2 and the second transmission device 3 for overturning through the feeding transmission line 81 and the discharging transmission line 82, and output through the discharging transmission line 82 after overturning, thereby greatly improving the automation and the efficiency of overturning the battery assembly.
As shown in fig. 2 and 3, a feed conveyor line 81 is provided upstream of the first conveyor 2 and the second conveyor 3, and a discharge conveyor line 82 is also provided downstream of the first conveyor 2 and the second conveyor 3. Because the interval between the feeding transmission line 81 and the discharging transmission line 82 and the first transmission device 2 and the second transmission device 3 is smaller, in order to avoid collision between the first transmission device 2 and the second transmission device 3 and the feeding transmission line 81 and the discharging transmission line 82 during overturning, the first transmission device 2 and the second transmission device 3 can be lifted to a certain height by the lifting driving device 5, and then the first transmission device 2 and the second transmission device 3 are driven to overturn by the rotating device 4.
The battery pack turning device can directly transfer the second tray 72 with the inverted battery pack 91 and the battery box 92 onto the first transfer device 2 and the second transfer device 3 for turning, so that the battery pack 91 and the battery box 92 are arranged in the right direction. In some embodiments, the battery assembly 91 and battery case 92 are also flipped with the first tray 71 engaged in place. As shown in fig. 6 to 9, a process of turning over the battery assembly 91 and the battery case 92 by using the first tray 71 in cooperation is schematically shown; as shown in fig. 6, before the battery pack 91 is turned over, the first transfer device 2 is positioned above the second transfer device 3, the first tray is transferred onto the second transfer device 3, the first tray 71 is positioned by the positioning pins 33 and the first tray 71 is clamped by the clamping unit 6, and then the first transfer device 2 and the second transfer device 3 are driven to rotate synchronously by the rotating device 4, so that the second transfer device 3 and the first tray 71 are positioned above the first transfer device 2 (i.e., the state shown in the upper half of fig. 7).
As shown in fig. 7, the second tray 72 loaded with the inverted battery pack 91 and the battery case 92 is then transferred to the first transfer device 2, the second tray 72 is positioned by the positioning pins 23 and clamped by the clamping assembly 6, then the first transfer device 2 and the second transfer device 3 are driven to move relatively by the lifting device 5 so that the first tray 71, the battery pack 91 and the battery case 92 and the second tray 72 are clamped (i.e., the state shown in the lower half of fig. 7), and finally the first transfer device 2 and the second transfer device 3 are driven to rotate synchronously by the rotating device 4 so that the battery pack 91 and the battery case 92 are placed on the first tray 71.
As shown in fig. 8, the first and second transfer devices 2 and 3 are then separated by being driven by the lifting device 5, and the second tray 72, which is loaded with the battery pack 91 and the battery case 92 after being turned upside down, is output by the second transfer device 3.
As shown in fig. 9, the first conveyor 2 and the second conveyor 3 are then clamped and rotated again, the second tray 72 and the first conveyor 2 are positioned below the second conveyor 3, and the empty second tray 72 is output from the first conveyor 2. The above is a process of turning over the battery assembly 91 with the aid of the first tray 71, and it can be seen that the process can turn over the battery assembly 91 and the battery case 92 turned over on the second tray 72 and be placed on the first tray 71, so that the battery assembly 91 does not need to directly contact the battery assembly turning apparatus during the turning over process, thereby avoiding scratching the battery assembly 91 and the battery case 92 during the turning over process and the subsequent transfer process. As shown in the lower half of fig. 9, when the plurality of battery packs 91 are continuously turned over, since the first tray 71 is already positioned on the second conveying device 3 and above the first conveying device 2, the steps of fig. 7 to 9 may be repeatedly performed without performing the steps shown in fig. 6 each time.
