[0034] The core of the present invention is to provide a battery cell positioning device, which is used to meet the battery cell positioning requirements while also having a high positioning efficiency.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the present invention discloses a battery cell positioning device, including a base portion 100, a battery cell fixture 200 and a driving positioning portion. The battery cell is placed on the battery cell fixture 200, and a first positioning block 210 and a second positioning block 220 are provided on the battery cell fixture 200. The extension direction of the first positioning block 210 and the extension direction of the second positioning block 220 are arranged perpendicular to each other. The battery cell fixture 200 is connected to the base portion 100 through a flip mechanism 300 of the driving positioning portion. The flip mechanism 300 can flip and tilt the battery cell fixture 200 toward the side where the first positioning block 210 is provided, so that the battery cell placed on the battery cell fixture 200 can slide to the first positioning block 2 10 and fit with the first positioning block 210, the first positioning block 210 positions the battery cell, and after the battery cell and the first positioning block 210 are stably fitted, the pushing mechanism 400 of the driving positioning part pushes the battery cell to move toward the second positioning block 220 until the battery cell and the second positioning block 220 fit together, and the battery cell is pressed and fixed by the pushing mechanism 400 and the second positioning block 220, so that the battery cell is positioned and fixed on the battery cell fixture 200, and finally the flipping mechanism 300 drives the battery cell fixture 200 to rotate and return to a horizontal state.

[0036] In a specific embodiment, the flipping mechanism 300 includes a first driving cylinder 310, a rotating plate 320 and a rotating portion 360. The fixed end of the first driving cylinder 310 is connected to the base portion 100, and the telescopic end of the first driving cylinder 310 is rotatably connected to the rotating plate 320. When the telescopic end of the first driving cylinder 310 is extended or retracted, the angle between the telescopic end of the first driving cylinder 310 and the rotating plate 320 is adjusted accordingly to ensure that the rotating plate 320 is flipped smoothly. The battery cell fixture 200 is installed on the side of the rotating plate 320 away from the first driving cylinder 310, and the rotating plate 320 is rotatably connected to the base portion 100 through the rotating portion 360. Therefore, the extension and retraction of the first driving cylinder 310 pushes the rotating plate 320 to rotate through the rotating portion 360, thereby realizing the flipping of the battery cell fixture 200 by the flipping mechanism 300.

[0037] like Figure 1 As shown, the flipping mechanism 300 includes a fixing ring 330, a first rotating shaft 340 and a first rotating shaft mounting seat 350. The telescopic end of the first driving cylinder 310 is connected to the first rotating shaft 340 through the fixing ring 330. The fixing ring 330 is rotatably mounted on the first rotating shaft 340, and the first rotating shaft 340 is fixed to the rotating plate 320 through the first rotating shaft mounting seat 350. The first rotating shaft mounting seat 350 is located on the side of the rotating plate 320 away from the battery fixture 200. Therefore, the first driving cylinder 310 is rotatably connected to the rotating plate 320 through the fixing ring 330, the first rotating shaft 340 and the first rotating shaft mounting seat 350.

[0038] like Figure 2 As shown, the battery cell positioning device provided in this embodiment also includes a fixing plate 500 and a connecting column 600, the fixing plate 500 is connected and fixed to the base portion 100 through the connecting column 600, the rotating portion 360 includes a second rotating shaft 361, a second rotating shaft mounting seat 362 and a connecting plate 363, the rotating plate 320 is connected to the second rotating shaft 361 through the connecting plate 363, the second rotating shaft 361 can be installed to the second rotating shaft mounting seat 362 through a bearing, and the bearing is limited and fixed by the bearing retaining ring 364, so that the second rotating shaft 361 can be rotatably connected to the second rotating shaft mounting seat 362 through the bearing, and the second rotating shaft mounting seat The seat 362 is installed and fixed on the fixed plate 500, thereby realizing the rotation of the rotating plate 320 through the rotating part 360. At the same time, when the rotating plate 320 is in a horizontal state, the rotating plate 320 is in contact with the fixed plate 500. The fixed plate 500 not only supports the rotating plate 320 and ensures that the rotating plate 320 has good stability in a horizontal state, but also limits the fixed plate 500. During the return process of the rotating plate 320, it is ensured that the rotating plate 320 can accurately stop on the horizontal plane. The fixed plate 500 is provided with an avoidance hole, so that the telescopic end of the first driving cylinder 310 is connected to the rotating plate 320 through the avoidance hole.

[0039] Furthermore, the rotating part 360 is also provided with a stop screw 365 and a connecting block 366, wherein the stop screw 365 is fixed to the fixed plate 500 through the connecting block 366, and a preset distance is set between the end face of the stop screw 365 and the connecting plate 363. Therefore, after the rotating part 360 rotates through the preset distance, the end face of the stop screw 365 abuts against the connecting plate 363, and the cooperation between the stop screw 365 and the connecting plate 363 plays a limiting role on the rotating part 360, that is, the battery cell fixture 200 stops rotating after rotating by a preset angle, so as to prevent the battery cell fixture 200 from rotating too much and causing the battery cell to fall from the battery cell fixture 200. In addition, the stop screw 365 and the connecting block 366 are connected by threads, so that according to actual needs, the stop screw 365 can be rotated to make the stop screw 365 move closer to or away from the connecting plate 363, so as to adjust the preset distance to adjust the rotation angle of the battery cell fixture 200.

[0040] like Figure 1 and Figure 2 As shown, the pushing mechanism 400 includes a second driving cylinder 410 and a positioning plate 420. The second driving cylinder 410 is installed on the rotating plate 320, so that the second driving cylinder 410 can rotate with the rotating plate 320. The telescopic end of the second driving cylinder 410 is connected to the positioning plate 420. The second driving cylinder 410 pushes the battery cell to move through the positioning plate 420, and the battery cell is pressed and fixed by the cooperation of the positioning plate 420 and the second positioning block 220, thereby realizing the pushing and fixing of the battery cell by the pushing mechanism 400.

[0041] In a specific embodiment, the pushing mechanism 400 is further provided with a buffer plate 430 and a cylinder buffer 440, the telescopic end of the second driving cylinder 410 is connected to the buffer plate 430, and the buffer plate 430 is fixed to the positioning plate 420, so that the telescopic end of the second driving cylinder 410 is connected to the positioning plate 420 through the buffer plate 430, and the cylinder buffer 440 is installed on the buffer plate 430, the axis of the cylinder buffer 440 is parallel to the telescopic direction of the second driving cylinder 410, and the cylinder buffer 440 is parallel to the telescopic direction of the second driving cylinder 410, and the cylinder buffer 440 is parallel to the rotating plate 320. A buffer gap is provided between the cylinder buffer 440 and the rotating plate 320. When the cylinder buffer 440 pushes the positioning plate 420 to move a distance that reaches the buffer gap, the cylinder buffer 440 abuts against the rotating plate 320, which limits the cylinder buffer 440 from continuing to push the positioning plate 420 to move, thereby playing a limiting role. Therefore, the buffer gap can be adjusted by the cylinder buffer 440 to adjust the stroke of the positioning plate 420 pushed by the second driving cylinder 410, thereby meeting the needs of positioning and fixing different types of battery cells, thereby improving the usability of the battery cell positioning device provided in this embodiment.

[0042] like Figure 2As shown, the base portion 100 includes a bottom plate 110, a transition plate 120, a cylinder mounting plate 130, a first adjusting block 140 and a second adjusting block 150. The first driving cylinder 310 is mounted and fixed on the cylinder mounting plate 130 through a cylinder bracket 311, and the cylinder mounting plate 130 is connected to the transition plate 120. At the same time, the connecting column 600 is installed and fixed on the transition plate 120, so that the fixing plate 500 is mounted on the transition plate 120 through the connecting column 600. The transition plate 120 is mounted on the base plate 110, and the base plate 110 can move in a first direction, and the transition plate 120 can move in a second direction, and the first direction and the second direction are perpendicular to each other. The first adjustment block 140 is connected to the base plate 110 to push the base plate 110 to move in the first direction through the first adjustment block 140, and the second adjustment block 150 is connected to the transition plate 120 to push the transition plate 120 to move in the second direction through the second adjustment block 150. By moving the base plate 110 and the transition plate 120 in the first direction and the second direction respectively, the position of the battery fixture 200 can be adjusted as a whole to cooperate with the robot arm to place the battery on the battery fixture 200. In a specific embodiment, the movement of the base plate 110 and the transition plate 120 can be achieved by a slide rail assembly, wherein the transition plate 120 and the base plate 110 are mounted on a slider in the slide rail assembly, and the two slide rails matched with the slider can extend in the first direction and the second direction respectively.

[0043] In another specific embodiment, the second positioning block 220 is provided with an adjustment groove, and the second positioning block 220 is installed and fixed to the battery cell fixture 200 through the adjustment groove, and the adjustment groove extends along the direction in which the pushing mechanism pushes the battery cell 400 to move, so that the position of the second positioning block 220 on the battery cell fixture 200 can be adjusted through the adjustment groove, and the distance between the second positioning block 220 and the battery cell can be adjusted, which can further adapt to the positioning and fixation of different types of battery cells, thereby improving the applicability of the battery cell positioning device provided in this embodiment.

[0044] like Figure 1 As shown, the present embodiment provides two battery cell fixtures 200 and two pushing mechanisms 400, one battery cell fixture 200 cooperates with one pushing mechanism 400, and the two battery cell fixtures 200 are arranged in sequence along the direction in which the pushing mechanism 400 pushes the battery cell to move. By performing positioning work simultaneously with the two battery cell fixtures 200, the working efficiency of the battery cell positioning device provided in the present embodiment is further improved.
