The cooperation and driving accuracy is high. However, the worm gear and worm wheel have large wear due to long-term planar friction meshing, resulting in a short service life and a significant impact on the accuracy of battery cell flipping.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this does not limit the present invention.

[0021] like Figures 1-5 As shown, this utility model discloses a multi-cell flipping mechanism, comprising a frame 1. The frame 1 is equipped with a connecting platform flipping mechanism 2, which includes a flipping drive mechanism 21 and multiple cell placement platforms 23. The flipping drive mechanism 21 includes a vertically arranged first connecting plate 2101, which is fixedly connected to the frame 1. Multiple first bearing seats 2107 are fixedly arranged on one side of the first connecting plate 2101. A first connecting shaft 2110 is rotatably arranged within any of the first bearing seats 2107, and one end of any of the first connecting shafts 2110 passes through the first connecting plate 2101 and... A turntable 2106 is connected, and the other end of any first connecting shaft 2110 is fixedly connected to one end of a cell placement platform 23. Multiple guide wheels 2104 are fixedly arranged on the periphery of one end of the turntable 2106. Support plates 2102 are provided at both ends of the other side of the first connecting plate 2101. Each of the support plates 2102 is provided with a second bearing seat 2108. The two ends of the camshaft 2105 are rotatably connected to the second bearing seat 2108. The camshaft 2105 is provided with a spiral guide groove. The guide wheels 2104 can roll along the side wall of the spiral guide groove of the camshaft 2105. A rotary drive device is provided at one end of the camshaft 2105.

[0022] Specifically, the cell placement platform 23 is used to clamp and limit the cell 3, and the flipping drive mechanism 21 is used to drive the cell placement platform 23 to flip. In the flipping drive mechanism 21, the helical guide groove of the camshaft 2105 cooperates with the guide wheel 2104 at one end of the turntable 2106 to drive the turntable 2106 to rotate. The turntable 2106 drives the first connecting shaft 2110 to rotate stably within the first bearing seat 2107. The first connecting shaft 2110 drives the cell placement platform 23 to flip, thus completing the flipping of the cell 3. The cooperation between the guide wheel 2104 and the helical guide groove of the camshaft 2105 is rolling friction, which has a small coefficient of friction, small precision loss, and long service life; while the traditional worm gear drive is sliding friction, which has a large coefficient of friction, large precision loss, and short service life. Setting helical guide grooves at multiple locations on the camshaft 2105 can simultaneously drive multiple turntables 2106 to rotate, thereby causing multiple cell placement platforms 23 to flip synchronously.

[0023] Furthermore, the connecting platform flipping mechanism 2 also includes an auxiliary flipping mechanism 22. The auxiliary flipping mechanism 22 includes a vertically arranged second connecting plate 2201. The second connecting plate 2201 is fixedly connected to the frame 1. The second connecting plate 2201 and the side of the first connecting plate 2101 with the first bearing seat 2107 are opposite to each other and parallel to each other. The second connecting plate 2201 is provided with a plurality of third bearing seats 2202 on the side opposite to the first connecting plate 2101. Each of the third bearing seats 2202 is rotatably provided with a second connecting shaft 2203. One end of each second connecting shaft 2203 is fixedly connected to the other end of a cell placement platform 23.

[0024] Specifically, such as Figure 4 As shown, the auxiliary flipping mechanism 22 is connected to the cell placement platform 23 via the second connecting shaft 2203. The second connecting shaft 2203 can rotate stably within the second bearing seat 2202. When the cell placement platform 23 is flipped, both ends are supported and limited by rotation, making the flipping of the cell placement platform 23 more stable.

[0025] Furthermore, the cell placement platform 23 includes a base plate 2301, a parallel gripper cylinder 2304, a guide rail slider mechanism, and a clamping block 2307. Connecting blocks 2302 are fixedly installed on both sides of the base plate 2301, and the two connecting blocks 2302 are respectively connected to the first connecting shaft 2110 and the second connecting shaft 2203. A through groove is formed in the middle of the base plate 2301, and a mounting plate 2303 is fixedly installed on the lower side of the groove. A clamping block 2307 is fixedly installed on the upper side of the mounting plate 2303. Equipped with a parallel gripper cylinder 2304, the guide rail slider mechanism includes a guide rail (not shown in the figure) fixedly installed on the upper side of the base plate 2301, sliders 2305 are respectively installed on both sides of the guide rail (not shown in the figure), and a sliding plate 2306 is installed on the upper side of any slider 2305. The two output ends of the parallel gripper cylinder 2304 are respectively connected to the sliders 2305, and a clamping block 2307 is fixedly provided on the upper side of any sliding plate 2306.

[0026] Specifically, such as Figure 5 As shown, the output end of the parallel gripper cylinder 2304 drives two sliders 2305 to approach or separate. The sliders 2305 drive the sliding plate 2306 to slide along the guide rail. The clamping blocks 2307 on the upper side of the two sliding plates 2306 cooperate with each other to clamp the battery cell 3. The parallel gripper cylinder 2304 can be set in the groove to make the structure more compact.

[0027] Furthermore, a battery cell limiting block 2310 is fixedly provided on one side of the upper side of the base plate 2301.

[0028] Specifically, such as Figure 5 As shown, the cell limiting block 2310 is set on one side of the upper side of the base plate 2301. The cell limiting block 2310 is higher than the sliding plate 2306. When the cell 3 is fed, it can limit the cell 3. When the cell placement table 23 is rotated 90°, it can support the cell 3 and prevent the cell 3 from falling out.

[0029] Furthermore, a plurality of slider limiting blocks 2308 are fixedly provided on the upper side of the base plate 2301, and the slider limiting blocks 2308 are provided at both ends of the stroke of the slider 2305.

[0030] Specifically, such as Figure 5 As shown, there are four slider limit blocks 2308, which are respectively set at the front and rear ends of the stroke of the two sliders 2305. They are used to limit the sliders 2305 when the parallel gripper cylinder 2304 drives the sliders 2305 to move, so that the sliders 2305 are accurately positioned.

[0031] Furthermore, a detection plate 2309 is provided on the lower side of the base plate 2301 of any of the aforementioned cell placement platforms 23, and a photoelectric sensor 2204 corresponding to the detection plate 2309 is fixedly provided on the second connecting plate 2201. Each photoelectric sensor 2204 is aligned with the position of the detection plate 2309 when a cell placement platform 23 is flipped into place.

[0032] Specifically, the number of photoelectric sensors 2204 is the same as that of the cell placement platform 23. The photoelectric sensors 2204 are installed through connectors and aligned with the position of the detection board 2309 when each cell placement platform 23 is flipped into place, and avoid interference with the flipping path of the cell placement platform 23. By using the photoelectric sensors 2204 and the detection board 2309 to sense, it is possible to detect whether the position of the cell after flipping is up to standard, which can improve safety and avoid unnecessary trouble caused by material leakage or falling, and avoid affecting subsequent work.

[0033] Furthermore, the rotary drive device is a servo motor 2103, which is mounted on a support plate 2102 on one side. The output shaft of the servo motor 2103 is connected to one end of the camshaft 2105 via a coupling 2109.

[0034] Specifically, the servo motor 2103 is fixedly mounted on the support plate 2102. The rotation angle of the camshaft 2105 can be precisely controlled by the servo motor 2103, thereby ensuring the rotation angle of the cell placement platform 23.

[0035] Furthermore, there are two connecting platform flipping mechanisms 2, with the two connecting platforms respectively located on both sides of the frame 1.

[0036] Specifically, setting up two docking platform flipping mechanisms 2 can significantly improve production efficiency and is suitable for large-scale production lines.

[0037] In use, the robotic arm places the battery cell 3 into the battery cell placement platform 23. The parallel gripper cylinder 2304 of the battery cell placement platform 23 drives the slider 2303 to move along the guide rail. The slider 2303 drives the sliding plate 2306 and the clamping block 2307 to clamp the battery cell 3. The servo motor 2103 drives the camshaft 2105 to rotate. Through the spiral guide groove of the camshaft 2105 and the guide wheel 2104, the turntable 2106 drives the first connecting shaft 2110 to rotate. The first connecting shaft 2110 drives the battery cell placement platform 23 to rotate 90° through the connecting block 2302. After rotating to a fixed angle, the photoelectric sensor 2204 is blocked by the detection plate 2309, which sends a signal to indicate that the flipping is complete.

[0038] In this utility model, the control terminal of the servo motor 2103, the signal output terminal of the photoelectric sensor 2204, and the control terminal of the parallel gripper cylinder 2304 are all connected to a controller via cables. The servo motor 2103, the photoelectric sensor 2204, the parallel gripper cylinder 2304, the controller, and their connection methods all adopt well-known technical solutions in the prior art, which are understood by those skilled in the art and will not be described in detail here.
