Description

Technical Field

[0001] This utility model relates to the technical field of battery cell processing, and in particular to a hot-hole device and a winding machine. Background Technology

[0002] During the battery cell production process, after the electrode winding is completed, the battery cell has a central hole. In order to meet the subsequent need to insert the core rod or bottom welding pin into the central hole of the battery cell, it is often necessary to heat the battery cell with a heat-heating device. The existing heat-heating device adopts contact heat-heating, which uses a heated heat-heating pin inserted into the hollow cavity of the battery cell. The heat-heating pin is used to heat the battery cell by contacting the inner wall of the battery cell. It is difficult to guarantee the consistency of each battery cell, resulting in different angles and positions to be processed after fixing. The existing heat-heating device has poor flexibility and cannot meet such heat-heating requirements. Utility Model Content

[0037] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many other different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] like Figure 1-3 As shown, in one embodiment of the hot-drilling device, the hot-drilling device includes a frame 1, a clamping mechanism 2, a pressure applying mechanism 3, a first driving mechanism 4, and a hot-drilling mechanism 5. The clamping mechanism 2 is mounted on the frame 1 and is used to clamp the battery cell 10. The portion of the clamping mechanism 2 used to clamp the battery cell 10 is rotatable relative to the main body of the clamping mechanism 2, so that the battery cell 10 can rotate relative to the clamping mechanism 2 when clamped. The pressure applying mechanism 3 is slidably connected to the frame 1. The pressure applying mechanism 3 includes a pressure applying drive module 31 and a pressure applying shaft 32. The drive end of the pressure applying drive module 31 is connected to the pressure applying shaft 32. The pressure applying shaft 32 rotates under the drive of the pressure applying drive module 31, so that it can drive the battery cell 10 to rotate when the pressure applying shaft 32 abuts against the side wall of the battery cell 10. The first driving mechanism 4 is mounted on the frame 1, and the pressure applying mechanism 3 is connected to the drive end of the first driving mechanism 4. The first driving mechanism 4 is used to drive the pressure applying mechanism 3 closer to or away from the side wall of the battery cell 10. The hot-drilling mechanism 5 is installed on the frame 1 and is used to hot-drill holes in the battery cell 10.

[0041] In this embodiment, by setting the battery cell 10 to be rotatable under the drive of the pressure mechanism 3 and the clamping mechanism 2, and by allowing the pressure mechanism 3 to move closer to or further away from the side wall of the battery cell 10 under the drive of the first drive mechanism 4, the overall rotational positioning is adopted, thereby enabling hole processing at different angles and positions, and adjusting the eccentricity, which increases the flexibility and multifunctionality of the overall hot-drilling device and solves the technical problem of poor flexibility of existing hot-drilling devices.

[0042] Preferably, the pressure applying mechanism 3 uses a high-precision encoder and a servo motor to control the rotation angle of the pressure applying shaft 32, ensuring that the position and orientation of each hole are accurate. In terms of stability, the pressure applying shaft 32 can be made of good materials, giving it good rigidity and stability, thereby maintaining the stability of the battery cell 10 under high-speed rotation and frequent start-stop conditions, avoiding vibration and deviation.

[0043] In one embodiment of the hot-hole device, the clamping mechanism 2 is connected to the drive end of the first drive mechanism 4 so that it can move together with the pressure applying mechanism 3.

[0044] In this embodiment, by connecting the clamping mechanism 2 to the drive end of the first drive mechanism 4, it can move together. The clamping mechanism 2 and the pressure mechanism 3 work together with the battery cell 10. Under the drive of a single drive source, the relative positions of the clamping mechanism 2 and the pressure mechanism 3 can be kept within a certain range. This reduces the complexity of the drive source and facilitates rapid coordination and response. For example, it can achieve the effect of pressing the rotating shaft 32 to hold down the battery cell 10 after the clamping mechanism 2 clamps it.

[0045] Furthermore, in one embodiment of the hot-hole device, the clamping mechanism 2 is connected to the pressure applying mechanism 3, so as to be connected to the driving end of the first driving mechanism 4 through the pressure applying mechanism 3.

[0046] In this embodiment, compared to the previous embodiment, the clamping mechanism 2 is further directly mounted on the pressure applying mechanism 3. This ensures the relative position and forms an integrated design to simplify the installation and maintenance process of the equipment, and reduces the risk of errors and failures caused by the combination of multiple components.

[0047] Specifically, in combination Figure 1 and 3As shown, the first drive mechanism 4 can be a linear drive module such as a cylinder, hydraulic cylinder, or linear motor. The drive end of the first drive mechanism 4 can be the first slider 41. The pressure drive module 31 can be a servo motor. The pressure mechanism 3 can also include a pressure seat 33. The pressure drive module 31 is mounted on the pressure seat 33. The pressure seat 33 is connected to the first slider 41. The drive shaft of the pressure drive module 31 can pass through the pressure seat 33 and be connected to the pressure rotating shaft 32. Thus, the outer surface of the pressure seat 33 can be used to connect the clamping mechanism 2.

[0048] More specifically, the structure of the pressure drive module 31 can be formed in various ways, such as transmitting the power of the motor through a belt, chain, or other means.

[0049] In one embodiment of the hot-drilling device, the hot-drilling mechanism 5 includes a linear hot-drilling drive module 51, a rotary hot-drilling drive module 52, a hot-drilling needle 53, and a heating pack 54. The hot-drilling needle 53 is connected to the drive end of the rotary hot-drilling drive module 52 and can rotate under the drive of the rotary hot-drilling drive module 52 to heat the central hole of the battery cell 10. The drive end of the linear hot-drilling drive module 51 is connected to the rotary hot-drilling drive module 52 and is used to drive the rotary hot-drilling drive module 52 and the hot-drilling needle 53 to approach or move away from the end of the battery cell 10. The heating pack 54 is located on the moving path of the hot-drilling needle 53. The heating pack 54 has a heating hole through which the hot-drilling needle 53 can pass and heat the hot-drilling needle 53. The heating hole and the hot-drilling needle 53 are located on the same reference plane.

[0050] In this embodiment, the heating needle 53, driven by the linear heating hole drive module 51, can approach or move away from the battery cell 10, thereby extending into the hole to be processed in the battery cell 10. Under the drive of the rotating heating hole drive module 52, it can rotate and heat the inner wall of the battery cell 10. The heating pack 54 is used to heat the heating needle 53. By placing the heating pack 54 and the heating needle 53 on the same reference plane, this embodiment can better control the heat transfer, ensure that the temperature distribution of the heating needle 53 is uniform throughout the working area, reduce the impact of temperature fluctuations on the hole quality of the battery cell 10, and ensure that the relative position between the heating pack 54 and the heating needle 53 remains fixed, thereby improving the accuracy of heating and heating.

[0051] Specifically, the driving end of the hot hole linear drive module 51 can be a combination of a lead screw and a slider structure, with a seat structure at both ends. The heating pack 54 is set on the seat structure so that the heating pack 54 is located on the moving path of the hot hole needle 53, forming an integrated hot hole mechanism 5.

[0052] In one embodiment of the hot-drilling device, the hot-drilling needle 53 is eccentrically connected to the drive end of the hot-drilling rotary drive module 52.

[0053] In this embodiment, by setting the hot-pressing needle 53 eccentrically, holes can be formed through rotational movement, making the edges of the holes smoother, reducing burrs and irregularities, and making the processed holes more approximately circular.

[0054] In one embodiment of the hot-drilling device, the hot-drilling device further includes a fixing seat 6, which is mounted on the frame 1 and located on the side of the clamping mechanism 2 away from the hot-drilling mechanism 5. The fixing seat 6 is provided with a fixing hole 61 for placing the end of the hot-drilling needle 53.

[0055] In this embodiment, by setting the fixing seat 6, the precise positioning of the heating needle 53 during insertion and withdrawal can be ensured, reducing errors caused by movement, and providing stable low support so that it will not shake or deviate from the preset path during the rotation heating of the heating hole.

[0056] In one embodiment of the hot-drilling device, the hot-drilling device further includes a rotating member, which is received within a fixed hole 61 and is at least partially rotatable relative to the fixed base 6. The rotating member is used to receive the end of the hot-drilling needle 53 that passes through the battery cell 10 and extends into the fixed hole 61.

[0057] In this embodiment, specifically, by providing a rotating component, the rotation of the heating needle 53 can be made more convenient, avoiding the impact on the work caused by the heating needle 53 rubbing against the inner wall of the fixing hole 61. The rotating component can be a structural component such as a bearing.

[0058] In conjunction with the previous embodiments, when the heating pin 53 is eccentrically set, the rotating member can also follow the heating pin 53 to move within the fixed hole 61. Alternatively, the size of the hole in which the rotating member is used to mate with the heating pin 53 can be larger than the diameter of the heating pin 53, allowing the heating pin 53 to rotate inside.

[0059] In one embodiment of the hot-drilling device, the hot-drilling device further includes a second driving mechanism 7, which is mounted on the frame 1. The driving end of the second driving mechanism 7 is connected to the fixed base 6 and is used to drive the fixed base 6 to move closer to or away from the hot-drilling mechanism 5.

[0060] In this embodiment, by setting the second drive mechanism 7, the position of the fixing seat 6 can be adjusted, thereby facilitating docking between the two ends of the battery cell 10 and the heating pin 53.

[0061] Specifically, the second drive mechanism 7 can be a linear drive module such as a cylinder, hydraulic cylinder, or linear motor, and the drive end of the second drive mechanism 7 can be a second slider, which pushes the fixed base 6 to move.

[0062] In one embodiment of the hot-drilling device, the clamping mechanism 2 includes a clamping drive module 21 and a gripper module. The drive end of the clamping drive module 21 is connected to the gripper module and is used to drive the gripper module to open and close. The gripper module includes at least two opposing gripper elements 22. Each gripper element 22 is equipped with a rotating part 221 that is rotatable relative to the gripper element 22. The rotating part 221 protrudes relative to the gripper element 22 body and is used to clamp the sidewall of the battery cell 10.

[0063] In this embodiment, specifically, the clamping mechanism 2 can be modified externally according to the driving method of the pneumatic fingers. To match the cylindrical shape of the battery cell 10, the gripper element 22 can be arc-shaped, and the rotating part 221 can adopt a structure such as a bearing or roller to cooperate in rotating and positioning the battery cell 10 and provide stable rotation. Preferably, multiple sets of gripper elements 22 can be symmetrically arranged along the axial direction of the battery cell 10, and each set is provided with a rotating part 221 to further provide a more stable rotation effect.

[0064] Furthermore, in conjunction with the preceding embodiments, the pressure-applying shaft 32 is located between the two opposing gripper elements 22.

[0065] In conjunction with the above embodiments, it should be emphasized and explained that the driving ends of each driving source in each embodiment of this utility model are either directly connected or indirectly connected. For example, linear driving can be directly connected to the end or indirectly driven through a slider, while motor rotation driving can be directly connected to the object to be rotated or indirectly driven through a connecting shaft or other structures.

[0066] This utility model also relates to a winding machine, including the hot-hole device in the above embodiment. It is understood that the winding machine also includes other devices for processing the battery cell 10, such as a device for winding the battery cell 10, an adhesive application device, etc., thereby constructing an overall processing flow from front to back. By applying the above-mentioned hot-hole device, the overall winding machine can achieve the technical effect of good hot-hole effect.

[0067] It is also understood that the frame 1 in the hot hole device embodiment is the same frame as the overall winding machine.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
