[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The features of the terms "first" and "second" in the specification and claims of the utility model may explicitly or implicitly include one or more of the features. In the description of the utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0024] Combine the following Figure 1-Figure 3 The utility model describes a battery core welding clamping device based on a turret and a battery core welding clamping system.

[0025] like Figure 1 As shown, in an embodiment of the utility model, the turret-based battery core welding clamping device includes a plurality of clamping mechanisms 10, each of which includes: a first clamping portion 11, a second clamping portion 12, an elastic member 13 and a follower wheel 15. One end of the first clamping portion 11 is connected to the follower wheel 15, and the second clamping portion 12 is arranged opposite to the first clamping portion 11. Both ends of the elastic member 13 are connected to the first clamping portion 11 and the second clamping portion 12, respectively.

[0026] Specifically, a plurality of clamping mechanisms 10 are arranged in an annular manner on the outer wall of the turret 200, and during the rotation of the turret 200, the plurality of clamping mechanisms 10 can be driven to rotate. The first clamping portion 11 and the second clamping portion 12 are used to clamp the battery cell, and the follower wheel 15 is connected to the turret 200 in a rolling manner. When the follower wheel 15 encounters an obstacle, the obstacle hinders the movement of the follower wheel 15, prompting the first clamping portion 11 to move away from the second clamping portion 12, so that the clamping mechanism 10 is in an open state. At this time, the elastic member 13 is in a stretched state, and the battery cell is located between the first clamping portion 11 and the second clamping portion 12. After the follower wheel 15 passes over the obstacle, the elastic member 13 contracts by elastic force, causing the first clamping portion 11 to move toward the second clamping portion 12, thereby clamping the battery cell.

[0027] The turret-based battery cell welding clamping device provided by the embodiment of the utility model has multiple clamping mechanisms, each of which can be automatically opened and closed, and no other auxiliary components are required to control the opening and closing of the clamping mechanism, which simplifies the structure of the clamping mechanism and reduces the manufacturing cost of the battery cell welding clamping device.

[0028] like Figure 1 As shown, in an embodiment of the utility model, the first clamping portion 11 includes a first clamping jaw 111, and the second clamping portion 12 includes a second clamping jaw 121. The second clamping jaw 121 is arranged opposite to the first clamping jaw 111, and the two ends of the elastic member 13 are respectively connected to the first clamping jaw 111 and the second clamping jaw 121, and the first clamping jaw 111 and the second clamping jaw 121 are used to clamp the battery.

[0029] Specifically, the first clamping jaw 111 and the second clamping jaw 121 are configured as the main body for clamping the battery cell. When the follower wheel 15 encounters an obstacle, the first clamping jaw 111 moves away from the second clamping jaw 121, so that the clamping mechanism 10 is in an open state. At this time, the elastic member 13 is in a stretched state, and the battery cell is located between the first clamping jaw 111 and the second clamping jaw 121. After the follower wheel 15 passes over the obstacle, the elastic member 13 contracts, so that the first clamping jaw 111 moves toward the second clamping jaw 121, thereby clamping the battery cell.

[0030] like Figure 1As shown, in the embodiment of the present utility model, the first clamping portion 11 further includes a first paddle 112, the first paddle 112 is connected to the first clamping jaw 111, and the first paddle 112 is provided with a first protrusion 1121. The second clamping portion 12 further includes a second paddle 122, the second paddle 122 is connected to the second clamping jaw 121, and the second paddle 122 is provided with a second protrusion 1221, and the second protrusion 1221 and the first protrusion 1121 can cooperate and slide when the first clamping portion 11 moves relative to the second clamping portion 12.

[0031] Specifically, when the clamping mechanism 10 is in a closed state, the first protrusion 1121 and the second protrusion 1221 fit together, and when the first clamping jaw 111 moves in a direction away from the second clamping jaw 121, the first protrusion 1121 and the second protrusion 1221 slide in cooperation to play a guiding role. Correspondingly, when the first clamping jaw 111 moves in a direction close to the second clamping jaw 121, the first protrusion 1121 also slides in cooperation with the second protrusion 1221 to play a guiding role, so as to prevent the second clamping jaw 121 and the first clamping jaw 111 from being misaligned during the movement and failing to clamp the battery cell.

[0032] Furthermore, in the embodiment of the present utility model, the first clamping jaw 111 includes a first body 1111 and a second body 1112 , the first body 1111 and the second body 1112 are connected at an angle, and the second body 1112 and the second clamping jaw 121 are arranged opposite to each other.

[0033] Specifically, in this embodiment, the length of the first clamping jaw 111 is greater than that of the second clamping jaw 121, and the first body 1111 and the second body 1112 are connected at an angle, so that the first clamping jaw 111 has a bending portion. The length of the second body 1112 is equal to that of the second clamping jaw 121, and the second body 1112 and the second clamping jaw 121 are configured to form a clamping body of the clamping mechanism 10.

[0034] like Figure 1 As shown, in an embodiment of the utility model, the first clamping jaw 111 is provided with a first through groove 1113 penetrating through the thickness of the first clamping jaw 111, and the second clamping jaw 121 is provided with a second through groove 123 penetrating through the thickness of the second clamping jaw 121, the first through groove 1113 and the second through groove 123 are arranged opposite to each other, and the first through groove 1113 and the second through groove 123 are configured to form a battery cell clamping hole 14.

[0035] Specifically, in this embodiment, the first through slot 1113 and the second through slot 123 are both semicircular holes, which are arranged opposite to each other to form the battery cell clamping hole 14. In the embodiment of the utility model, the first protrusion 1121 and the second protrusion 1221 cooperate and slide, so that when the first clamping jaw 111 moves away from or close to the second clamping jaw 121, it can play a guiding role to prevent the first through slot 1113 and the second through slot 123 from being misaligned, thereby preventing the battery cell from being unable to be clamped.

[0036] Furthermore, in the embodiment of the present invention, the battery cell holding hole 14 extends from the middle to the lower part to form a gradually expanding structure, so as to facilitate the battery cell to penetrate into the battery cell holding hole 14. Furthermore, the inner wall of the battery cell holding hole 14 is also provided with an anti-slip coating to prevent the battery cell from falling during the clamping and transportation process.

[0037] like Figure 2 and Figure 3 As shown, the embodiment of the utility model further provides a battery core welding clamping system, including: a turret 200 and a battery core welding clamping device based on the turret.

[0038] Specifically, the cam 202 is located above the turntable 201, the diameter of the cam 202 is smaller than the diameter of the turntable 201, and a limiting structure 2021 is provided on part of the outer edge of the cam 202. The battery core welding clamping device includes a plurality of clamping mechanisms 10, which are arranged in a ring along the circumferential direction of the turntable 201. When the turntable 201 rotates, the plurality of clamping mechanisms 10 can be driven to rotate. When a clamping mechanism 10 rotates to the limiting structure 2021, the limiting structure 2021 blocks the movement of the clamping mechanism 10, causing the clamping mechanism 10 to be in an open state, so that the battery core can be located in the clamping mechanism 10; when the clamping mechanism 10 passes over the limiting structure 2021, the clamping mechanism 10 closes, thereby clamping the battery core, and driven by the turntable 201, the battery core is clamped to the welding station.

[0039] Furthermore, in this embodiment, when each clamping mechanism 10 moves to the limiting structure 2021, the clamping mechanism 10 can clamp one battery cell, thereby continuously transporting the battery cells to the welding station.

[0040] The battery cell welding clamping system provided by the embodiment of the utility model realizes automatic opening and closing of the battery cell welding clamping device by setting a turret and a battery cell welding clamping device, and the battery cell welding clamping device cooperates with a limiting structure. No other auxiliary components are required to control the opening and closing of the battery cell welding clamping device, which simplifies the structure of the battery cell welding clamping device and reduces the manufacturing cost of the battery cell welding clamping system.

[0041] Furthermore, if Figure 3 As shown, in the embodiment of the present utility model, an arc-shaped protrusion is provided on the outer edge of the cam 202 , and the arc-shaped protrusion is configured as a limiting structure 2021 .

[0042] Furthermore, each clamping mechanism 10 includes: a first clamping portion 11, a second clamping portion 12, an elastic member 13 and a follower wheel 15. One end of the first clamping portion 11 is rollingly connected to the outer edge of the cam 202 through the follower wheel 15, the first clamping portion 11 and the second clamping portion 12 are both connected to the turntable 201, and the second clamping portion 12 is arranged opposite to the first clamping portion 11. The two ends of the elastic member 13 are respectively connected to the first clamping portion 11 and the second clamping portion 12. When the follower wheel 15 abuts against the arc-shaped protrusion, the first clamping portion 11 moves in a direction away from the second clamping portion 12, the elastic member 13 is in an extended state, and the clamping mechanism 10 is in an open state; after the follower wheel 15 passes over the arc-shaped protrusion, the elastic member 13 drives the first clamping portion 11 to move in a direction close to the second clamping portion 12, and the clamping mechanism 10 is in a closed state, thereby clamping the battery cell.

[0043] Further, the first clamping portion 11 includes a first clamping jaw 111, the first clamping jaw 111 is rollingly connected to the cam 202, and the first clamping jaw 111 is connected to the rotating disk 201. The second clamping portion 12 includes a second clamping jaw 121, the second clamping jaw 121 is arranged opposite to the first clamping jaw 111, and the second clamping jaw 121 is connected to the rotating disk 201. The two ends of the elastic member 13 are respectively connected to the first clamping jaw 111 and the second clamping jaw 121, and the first clamping jaw 111 and the second clamping jaw 121 are used to clamp the battery.

[0044] Specifically, the first clamping jaw 111 and the second clamping jaw 121 are configured as the clamping body of the clamping mechanism 10. The first clamping jaw 111 is rollingly connected to the cam 202 through the follower wheel 15, and the first clamping jaw 111 and the second clamping jaw 121 can be driven to move when the turntable 201 rotates. When the follower wheel 15 abuts against the limiting structure 2021, the first clamping jaw 111 moves away from the second clamping jaw 121, so that the clamping mechanism 10 is in an open state; when the follower wheel 15 passes over the limiting structure 2021, the first clamping jaw 111 moves toward the direction close to the second clamping jaw 121 driven by the elastic member 13 to clamp the battery cell.
