[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] Please combine them together Figures 1 to 5 The hot-hole mechanism provided by this utility model will now be described. The hot-hole mechanism is used in battery cell winding equipment.

[0034] The hot-drilling mechanism includes a frame 1, a first drive assembly 2, a second drive assembly 3, a hot-drilling needle 4, a heating tube 5, and a transfer assembly 6. The first drive assembly 2 is mounted on the frame 1 and connected to the second drive assembly 3, enabling the first drive assembly 2 to move. The second drive assembly 3 is connected to the hot-drilling needle 4 and is used to rotate the hot-drilling needle 4. The heating tube 5 is mounted on the frame 1 and is used to heat the hot-drilling needle 4. The transfer assembly 6 is mounted on the frame 1 and is used to transfer and fix the battery cells. The frame 1, the first drive assembly 2, the second drive assembly 3, the hot-drilling needle 4, and the heating tube 5 are all located at the rear of the large plate 100. Specifically, the large plate 100 can be a protective plate in a winding device.

[0035] Understandably, the first drive assembly 2 of the hot-scalding mechanism is mounted on the frame 1 and connected to the second drive assembly 3. The first drive assembly 2 can drive the first drive assembly 3 to move. The second drive assembly 3 is connected to the hot-scalding needle 4 and is used to drive the hot-scalding needle 4 to rotate. The heating tube 5 is mounted on the frame 1 and is used to heat the hot-scalding needle 4. The transfer assembly 6 is mounted on the frame 1 and is used to transfer and fix the battery cell. The frame 1, the first drive assembly 2, the second drive assembly 3, the hot-scalding needle 4 and the heating tube 5 are all placed at the rear of the large plate 100, so that most of the entire mechanism can be placed at the rear of the large plate 100, reducing the space at the front, reducing the size of the equipment, and making it easier to operate and observe, and more convenient to debug. In addition, placing the heating tube 5 at the rear of the large plate 100 is safer.

[0036] It should be noted that after the heating tube 5 heats the heating needle 4 for a certain period of time, the first driving component 2 drives the second driving component 3 to move closer to the battery cell. The second driving component 3 drives the heating needle 4 to move. At the same time, the second driving component 3 drives the heating needle 4 to rotate, and the heating needle 4 heats the center of the battery cell.

[0037] In this embodiment, the first drive assembly 2 includes a first drive motor 21, a lead screw 22, a lead screw nut 23, and a connector 24. The first drive motor 21 is mounted on the frame 1. The first drive assembly 2 is connected to the lead screw 22 and is used to drive the lead screw 22 to rotate. The lead screw 22 is connected to the lead screw nut 23 in a transmission connection. The connector 24 is connected to the lead screw nut 23 and is also connected to the second drive assembly 3. Specifically, the first drive motor 21 drives the lead screw 22 to rotate. The lead screw 22 is threadedly connected to the lead screw nut 23. The lead screw 22 drives the lead screw nut 23 to move. The lead screw nut 23 drives the connector 24 to move. The connector 24 drives the second drive assembly 3 and the heating needle 4 to move closer to the battery cell.

[0038] Furthermore, the first drive assembly 2 also includes a guide 25, which is mounted on the frame 1. The guide 25 and the connector 24 are slidably connected, and the guide 25 is used to guide the movement direction of the connector 24. Specifically, the guide 25 can be a guide rail. During the movement of the connector 24 driven by the nut 23, the connector 24 moves along the guide 25, thereby guiding the movement direction of the connector 24.

[0039] Furthermore, the first drive assembly 2 also includes a sensing plate 26 and two sensors 27. Both sensors 27 are mounted on the frame 1 and are located at opposite ends of the travel distance of the connector 24. The sensing plate 26 is mounted on the connector 24, and the sensors 27 are used to sense the sensing plate 26. Specifically, the two sensors 27 can be position sensors 27. When the connector 24 moves, it drives the sensing plate 26 to move. When the sensing plate 26 moves to the corresponding sensor 27, the sensor 27 can sense the position of the sensing plate 26, thereby locating the position of the heating pin 4.

[0040] Furthermore, the first drive assembly 2 also includes two adjusting members 28, both mounted on the frame 1 and connected to the two sensors 27 respectively. Each adjusting member 28 can adjust the position of the two sensors 27. Specifically, each adjusting member 28 has a sliding groove, allowing the sensors 27 to move within the groove, thus changing their position. Once adjusted, the sensors 27 are fixed in their current position. The sensors 27 can be secured in their current position within the sliding groove using bolts.

[0041] In one embodiment, such as Figure 2 and Figure 3 As shown, the first drive assembly 2 also includes a first limiting member 29 and a second limiting member 291. Both the first limiting member 29 and the second limiting member 291 are mounted on the frame 1. The first limiting member 29 and the second limiting member 291 are arranged opposite each other to form a gap and are used to limit the position of the connector 24. When the connector 24 drives the second drive assembly 3 and the heating needle 4 to move to a designated position, the first limiting member 29 and the second limiting member 291 can limit the connector 24, thereby preventing the connector 24 from colliding or interfering with other components.

[0042] In one embodiment, such as Figure 2 and Figure 3 As shown, the second drive assembly 3 includes a bracket 31, a second drive motor 32, and a transmission module 33. The second drive motor 32 is connected to the connector 24 via the bracket 31, and the second drive motor 32 is connected to the transmission module 33. The transmission module 33 is connected to the heating pin 4. Specifically, the second drive motor 32 drives the transmission module 33 to rotate the heating pin 4, so that the heating pin 4 can heat a hole in the center of the battery cell.

[0043] In this embodiment, the transmission module 33 includes a drive wheel 331, a driven wheel 332, and a belt 333. The drive wheel 331 is connected to the second drive motor 32, the driven wheel 332 is rotatably connected to the bracket 31 and connected to the heating needle 4, and the belt 333 surrounds the drive wheel 331 and the driven wheel 332. Specifically, the second drive motor 32 drives the drive wheel 331 to rotate, the drive wheel 331 drives the belt 333 to move, the belt 333 drives the driven wheel 332 to rotate, and the driven wheel 332 drives the heating needle 4 to rotate.

[0044] In one embodiment, such as Figure 2 As shown, the transfer assembly 6 includes a moving module 61 and a gripper 62. The moving module 61 is connected to the frame 1 and the gripper 62, and is used to drive the gripper 62 to move the battery cell. Specifically, the moving module 61 can drive the gripper 62 to move, and the gripper 62 then drives the battery cell to move, so that the center of the heating pin 4 and the center of the battery cell are on the same axis, thereby positioning the battery cell.

[0045] This utility model also provides a battery cell winding device, which includes the hot-hole mechanism of any of the above embodiments.

[0046] It is understood that the battery cell winding equipment of this utility model uses the above-mentioned hot-hole mechanism, so that the first drive component 2 of the hot-hole mechanism is installed on the frame 1 and connected to the second drive component 3. The first drive component 2 can drive the first drive component 3 to move. The second drive component 3 is connected to the hot-hole needle 4 and is used to drive the hot-hole needle 4 to rotate. The heating tube 5 is installed on the frame 1 and is used to heat the hot-hole needle 4. The transfer component 6 is installed on the frame 1 and is used to transfer and fix the battery cell. The frame 1, the first drive component 2, the second drive component 3, the hot-hole needle 4 and the heating tube 5 are all placed at the rear of the large plate 100, so that most of the entire mechanism can be placed at the rear of the large plate 100, reducing the space at the front, reducing the size of the equipment, and making it easier to operate and observe, and more convenient to debug.
