Detailed Description of the Embodiment

[0021] In order to more clearly understand the technical means of the present utility model and be able to implement it according to the content of the specification, the following further describes in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0022] As Figures 1 to 2 shown, the blade battery cell flipping mechanism of the present utility model is used to flip the blade battery cell at the flipping station of the conveying line, and includes a carrying bracket 1 and a flipping mechanism 2 and a lifting mechanism 3 provided on the carrying bracket 1. The lifting mechanism 3 is arranged below the flipping mechanism 2 and is used to lift the tray for loading the blade battery cell before flipping and unloading the blade battery cell after flipping. The carrying bracket 1 includes an upper bracket 11 and a lower bracket 12, and the flipping mechanism 2 and the lifting mechanism 3 are respectively arranged on the upper bracket 11 and the lower bracket 12.

[0023] As Figure 3 , the flipping mechanism 2 includes two groups of cross beams 21 arranged oppositely and a clamping assembly 22 whose two ends are respectively rotatably connected to the cross beams 21 through linear bearings. The clamping assembly 22 is located between the two cross beams 21 and is used to clamp the blade battery cell, and includes a flipping plate 221, two groups of clamping jaws 222 arranged oppositely and a clamping driving member 223 for driving the clamping jaws 222 to move relatively. Rotating shafts are provided at both ends of the flipping plate 221, and the rotating shafts pass through the linear bearings and are rotatably connected with the linear bearings in cooperation; the clamping driving member 223 is fixedly arranged on the flipping plate 221, and the clamping driving member 223 has two output ends extending along the direction of the flipping plate 221, and the two output ends are respectively connected with the two groups of clamping jaws 222.

[0024] Further, a bracket 224 extending towards the blade battery cell is provided at the lower part of the flipping plate 221, and the bracket 224 cooperates with the clamping jaws 222 to clamp the blade battery cell to prevent the blade battery cell from slipping.

[0025] Further, the clamping assembly 22 further includes a sliding unit, and the sliding unit includes a slider and a slide rail that slidably cooperates with the slider. In this embodiment, the slide rail is arranged on the flipping plate 221, and the clamping jaws 222 are slidably connected to the flipping plate 221 through the slider.

[0026] Further, the flipping mechanism 2 is further provided with a detection assembly 23, and the detection assembly 23 includes a photoelectric sensor 231 and a proximity sensor 232. The photoelectric sensor 231 is used to detect whether the blade battery cell is clamped in place; there are two groups of proximity sensors 232, and the two groups of proximity sensors 232 cooperate with the light shielding sheets on the flipping plate 221 and are respectively arranged corresponding to the initial position and the flipping position of the flipping plate 221, and are used to detect whether the flipping plate 221 is in the initial position or the flipping position.

[0027] In this embodiment, multiple sets of clamping assemblies 22 can be designed according to the number of blade-shaped battery cells, and the multiple sets of clamping assemblies 22 are evenly arranged along the length direction of the cross beam 21.

[0028] One end of the rotating shaft is fixedly connected to the flipping plate 221, and the other end of the rotating shaft is provided with a robotic arm 24 that is drivingly connected to the rotating shaft. The robotic arm 24 drives the rotating shaft to rotate under the driving action of the flipping driving member 25. The flipping driving member 25 can adopt a telescopic air cylinder, and the telescopic air cylinder is arranged outside the cross beam 21.

[0029] When there are multiple sets of blade-shaped battery cells, the corresponding multiple sets of rotating shafts are respectively rotatably connected to the same connecting member 26 through multiple sets of robotic arms 24. The output end of the telescopic air cylinder is connected to the connecting member 26. Under the telescopic driving of the telescopic air cylinder, the connecting member 26 moves back and forth along the extending direction of the cross beam 21.

[0030] Further, limiting members 27 are provided at both the head end and the tail end of the moving stroke of the connecting member 26. By limiting the moving stroke of the connecting member 26 through the limiting members 27, the swinging angle of the robotic arm 24 is limited. That is, by adjusting the distance between the limiting members 27, the flipping angle of the flipping plate 221 can be adjusted, including but not limited to the flipping plate 221 driving the blade-shaped battery cell to flip by 90°.

[0031] Such as Figure 4 , the lifting mechanism 3 includes a mounting plate 31 fixedly connected to the lower support 12, a lifting driving member 32 fixedly arranged below the mounting plate 31, and a bearing plate 33 that moves up and down relative to the mounting plate 31 under the driving of the lifting driving member 32. The tray is lifted to a set position by the bearing plate 33 for loading the blade-shaped battery cells to be flipped and unloading the blade-shaped battery cells after flipping. Specifically, the output end of the lifting driving member 32 is fixedly connected to the bottom of the bearing plate 33.

[0032] Further, guide rods 34 for guiding the bearing plate 33 to move up and down vertically are provided at the four corners of the bearing plate 33. The guide rods 34 are slidably connected to the mounting plate 31 through linear bearings, avoiding horizontal displacement when the bearing plate 33 drives the carrier to move up and down, and improving the stability of the bearing plate 33 when moving up and down.

[0033] Further, the free ends of two adjacent guide rods 34 are connected to each other, further improving the smoothness of the bearing plate 33 when moving up and down.

[0034] Locking assemblies 4 are provided on both sides of the flipping station along the conveying direction of the tray, such as Figure 5As shown in the figure, the locking assembly 4 includes a limiting block 41 arranged at the head end along the conveying direction and a positioning stopper 42 arranged at the tail end along the conveying direction. When the tray is conveyed to the turning station, the limiting block 41 is reset under the elastic action of the elastic member and abuts against one side of the tray. The positioning stopper 42 includes a positioning driving cylinder and a stop baffle. A roller is provided at one end of the stop baffle away from the positioning driving cylinder. The cylinder output end of the positioning driving cylinder is fixedly connected to the stop baffle. Under the driving action of the positioning driving cylinder, the roller rises with the stop baffle. Under the pushing action of the tray, the stop baffle and the roller tilt up and block the tray. The tray is locked through the cooperation of the limiting block 41 and the stop baffle to prevent the tray from displacing during the feeding and discharging processes of the blade battery cells.

[0035] The working principle of this embodiment is as follows: When the blade battery cells are conveyed to the turning station with the tray, after the tray is lifted and lowered to the set position by the lifting mechanism 3, it is locked by the locking assembly 4. The external manipulator picks up the blade battery cells and places them on the bracket 224 of the turning mechanism 2. At the same time, the clamping driving member 223 is started to drive the jaws 222 to move relatively closer and clamp the blade battery cells. When the photoelectric sensor 231 detects that the blade battery cells have been clamped in place, and at the same time the proximity sensor 232 detects that the turning plate 221 is in the initial position, the stroke of the telescopic cylinder is retracted. The robotic arm 24 swings and drives the rotating shaft to rotate, and at the same time drives the turning plate 221 and the blade battery cells to turn. When the proximity sensor 232 detects that the turning plate 221 is in the turning position, the tray is lifted and the 90°-turned blade battery cells are discharged. Subsequently, the tray descends with the lifting mechanism 3 and transports the blade battery cells into the next process. At the same time, the stroke of the telescopic cylinder is extended and the turning plate 221 is reset.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
