[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] like Figure 1 As shown, a battery cell clamping mechanism of a preferred embodiment of the present invention includes a first fixing part 1, which is plate-shaped and has a first direction X and a second direction Y intersecting with each other, wherein the first direction X is the thickness direction of the first fixing part 1, and the second direction Y is the length direction of the first fixing part 1; preferably, the first direction X and the second direction Y are arranged perpendicular to each other.

[0029] A battery cell clamping mechanism according to a preferred embodiment of the present invention further includes a clamping member 2, a driving member 3, a rotating member 4 and a sliding member 5. The clamping member 2, the driving member 3, the rotating member 4 and the sliding member 5 are sequentially arranged along the first direction X. There are at least two clamping members 2, the rotating member 4 and the sliding member 5, and they are symmetrically arranged on both sides of the first fixed part 1 and the driving member 3 in the second direction Y. The clamping member 2 is slidably connected to the first fixed part 1 in the first direction X, specifically located at the bottom of the first fixed part 1. The clamping member 2 can move along the second direction Y. During operation, the driving member 3 drives the two clamping members to slide along the second direction Y to clamp the battery cell. The driving member 3 is arranged at the other end of the first fixed part 1 relative to the clamping member 2. The driving member 3 is connected to the clamping member 2 and drives the two clamping members to slide along the second direction Y to clamp the battery cell during operation. One end of the rotating member 4 is rotatably connected to the end of the first fixed part 1 facing away from the clamping member 2, and the other end is connected to the clamping member 2. Connecting the sliding member 5, when the position of the battery cell is not accurate, it may cause uneven force on the clamping members 2 on both sides. At this time, the rotating member 4 on the side of the clamping member 2 with greater force will drive one end of the first fixed part 1 to rotate. The rotating first fixed part 1 can drive the clamping member 2 on the side with greater force to adapt flexibly, and the rotating member 4 unloads the force through the sliding member 5 connected on the other side. The sliding member 5 is connected to the other end of the rotating member 4 facing away from the first fixed part 1. The sliding member 5 can move in the first direction X to unload the force transmitted by the rotating member 4. The present application flexibly adapts the clamped battery cell by the sliding member 5, rotating member 4, first fixed part 1 and clamping member 2 connected in sequence in the first direction X, thereby reducing the accidents of the clamping member 2 crushing or knocking the battery cell when the driving mechanism of the clamping member 2 is not accurate or the positioning of the tray fails, thereby improving the fault tolerance and yield rate of the equipment.

[0030] In some embodiments of the present invention, a second fixing portion 6 is further included. The second fixing portion 6 is configured in a T-shape. The second fixing portion 6 is connected to an external robotic arm in the first direction X, and the robotic arm drives the clamping mechanism to move as a whole. A sliding member 5 is slidably connected to the bottom of the T-shape. The sliding member 5 is slidably connected to the end surface of the second fixing portion 6 along the second direction Y and can slide along the first direction X. The movement stroke of the sliding member 5 in the first direction X is the force unloading stroke of the rotating member 4. The unbalanced force applied to the clamping member 2 is transferred through the rotating member 4 and ultimately converted into the sliding stroke of the sliding member 5 on the second fixing portion 6, so that the unbalanced force applied to the clamping member 2 is sufficiently flexible and buffered.

[0031] In some embodiments of the present invention, two sliding members 5 are symmetrically provided at both ends of the second fixed portion 6 along the second direction Y. The two sliding members 5 are provided corresponding to the two clamping members 2. The two sliding members 5 are both connected to the rotating members 4 symmetrically provided along the second direction Y. Both ends of each rotating member 4 are respectively connected to the sliding members 5. When the force on one side of the clamping member 2 is uneven, the force will be transferred to the rotating member 4 and the sliding member 5. The symmetrical arrangement of the two sliding members 5 and the rotating member 4 enables the two clamping members 2 of the clamping mechanism to be fully unloaded when the force is uneven, thereby preventing damage to the clamping members 2 or the battery cells on both sides.

[0032] In some embodiments of the present invention, a second slide rail 61 is provided on the end face of the second fixed portion 6 along the second direction Y, the second slide rail 61 extends along the first direction X, the sliding member 5 is slidably connected to the second slide rail 61, and the second slide rail 61 is also provided in two corresponding to the sliding member 5; specifically, the second slide rail 61 includes a linear protrusion extending along the first direction X, and a recessed linear groove is provided on the end face of the sliding member 5 facing the slide rail, and the linear protrusion is engaged in the linear groove, thereby limiting the sliding member 5 and keeping the sliding member 5 sliding in the first direction X.

[0033] In some embodiments of the present invention, two rotating parts 4 are also provided, and the two rotating parts 4 are symmetrically arranged on both sides of the second fixed part 6 along the second direction Y. The ends of the two rotating parts 4 facing away from the second fixed part 6 are respectively connected to the top end faces of the first fixed part 1, and the two ends of the first fixed part 1 in the second direction Y are respectively connected to a rotating part 4, and the ends of the rotating parts 4 facing the second fixed part 6 are respectively rotatably connected to the two sliding parts 5. The two rotating parts 4 are symmetrically arranged so that when the two clamping parts 2 of the clamping mechanism are subjected to uneven force, both can obtain sufficient force unloading, thereby preventing damage to the clamping parts 2 on both sides or the battery cells.

[0034] In some embodiments of the present invention, two first protrusions 11 are symmetrically provided on the end face of the first fixing portion 1 facing the rotating member 4. A groove is formed on the side of the rotating member 4 near the first protrusion 11 to accommodate the first protrusion 11, and the first protrusion 11 is extended into the groove. A through hole is provided on the first protrusion 11 for inserting the rotating shaft, and a corresponding through hole is also provided on the rotating member 4. The rotating shaft passes through the first protrusion 11 and the through hole on the rotating member 4, so that one end of the two rotating members 4 is rotatably connected to the two first protrusions 11 respectively. The provision of the first protrusion 11 and the groove ensures that the fixing between the rotating member 4 and the first fixing portion 1 is firm and the rotation process of the rotating member 4 is stable.

[0035] In some embodiments of the present invention, a second protrusion 12 is provided on the end surface of the first fixing portion 1 along the first direction X. The second protrusion 12 is provided on the end surface of the first fixing portion 1 facing away from the first protrusion 11. A first slide rail 13 extending along the second direction Y is provided on the end surface of the second protrusion 12 along the first direction X. The first slide rail 13 protrudes toward the clamping member 2, and the clamping member 2 is slidably connected to the first slide rail 13. Specifically, a groove is formed on the end surface of the clamping member 2 in the first direction X facing the first slide rail 13. The groove and the size of the first slide rail 13 match so that the clamping member 2 can be stably mounted on the first slide rail 13 and slide along the first slide rail 13.

[0036] Furthermore, two second protrusions 12 are provided, and the two second protrusions 12 are symmetrically distributed at both ends of the first fixing portion 1 along the second direction Y. The two second protrusions 12 are both provided with a first slide rail 13 extending along the second direction Y. The two first slide rails 13 are collinearly arranged, and the two second protrusions 12 are both arranged on the end surface of the first fixing portion 1 facing away from the first protrusion 11. Two clamping members 2 are also provided and are respectively slidably connected to the first slide rail 13. The two clamping members 2 can move in the same direction or opposite directions during the movement to clamp and transport the battery cells located under the clamping mechanism.

[0037] In some embodiments of the present invention, the first fixing portion 1 is provided with a through hole 14 along the first direction X. The through hole 14 penetrates the first fixing portion 1 in the first direction X. The driving member 3 is arranged on one side of the first fixing portion 1 along the first direction X, specifically on the side of the first fixing portion 1 facing the second fixing portion 6. The clamping member 2 is arranged on the other side of the first fixing portion 1 along the first direction X. The clamping member 2 and the driving member 3 are respectively arranged on both sides of the first fixing portion 1 in the first direction X. The driving member 3 is connected to the clamping member 2 through the through hole 14. Separating the driving member 3 from the clamping member 2 can save space. Integrating the driving member 3 on the other side of the first fixing portion 1 also fully ensures the clamping range of the clamping member 2. Furthermore, the driving member 3 includes a motor or a cylinder.

[0038] In some embodiments of the present invention, the driving member 3 includes two connecting rods 31, which are transmission members of the driving member 3. One end of the connecting rod 31 is connected to the driving member 3, and the other ends of the two connecting rods 31 pass through the through hole 14 and extend along both sides of the second direction Y respectively. The two connecting rods 31 are respectively connected to the two clamping members 2. When the driving member 3 is started, it outputs power, and the power can be transmitted to the clamping member 2 through the two connecting rods 31, so that the clamping member 2 can clamp and release the battery cell.

[0039] The working process of the utility model is as follows: two opposite clamping parts 2 are slidably connected to the first fixing part 1, and the driving part 3 drives the two clamping parts to slide along the second direction Y to clamp the battery cell; when the battery cell is clamped in an inaccurate position, it may cause uneven force on the clamping parts 2 on both sides. At this time, the rotating part 4 on the side of the clamping part 2 with greater force will drive one end of the first fixing part 1 to rotate, and the rotating first fixing part 1 can drive the clamping part 2 on the side with greater force to adapt flexibly, and the rotating part 4 unloads the force through the sliding part 5 connected on the other side, and the sliding part 5 will rotate the rotating part 4 during the sliding process.

[0040] In summary, an embodiment of the utility model provides a battery cell clamping mechanism, which flexibly adapts to the clamped battery cells through a sliding member 5, a rotating member 4, a first fixed part 1 and a clamping member 2 connected in sequence in a first direction X, thereby reducing accidents in which the battery cells are crushed or damaged by the clamping member 2 when the driving mechanism of the clamping member 2 is inaccurate or the positioning of the tray fails, thereby improving the fault tolerance and yield rate of the equipment.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
