Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping mechanism and a strapping machine for bundling lithium batteries. Background Technology

[0002] In the assembly of lithium battery modules, battery pack bundling is a crucial step to ensure structural stability and safety. Currently, the industry commonly uses steel strips to bundle and secure the battery packs. However, existing lithium battery pack bundling machines typically employ a single-sided clamping method during the clamping and positioning process, meaning that clamping force is applied only from one side of the battery pack. This clamping method has the following problems: 1. Uneven stress: Since the clamping force is applied from only one side, the battery pack is prone to uneven stress distribution during the bundling process, resulting in excessive local pressure, which may cause the battery casing to deform or even burst, posing a safety hazard.

[0003] 2. Poor bundling stability: Clamping on one side makes it difficult to ensure that the overall force of the bundled battery pack is balanced. After long-term use, it may loosen, affecting the structural stability and electrical performance of the battery module.

[0004] 3. Insufficient adaptability: Different models of lithium battery packs have different thicknesses, and the traditional single-sided clamping mechanism has a limited adjustment range, making it difficult to flexibly adapt to the bundling needs of different specifications of battery cells.

[0005] Therefore, there is an urgent need for an improved clamping mechanism to solve the problems of uneven force, poor safety and insufficient adaptability caused by the single-sided clamping of existing strapping machines, thereby improving the stability and reliability of lithium battery pack strapping. Summary of the Invention

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a clamping mechanism for bundling lithium batteries, which can achieve synchronous clamping and positioning of lithium battery modules on both sides, has a high safety factor, and can also achieve shaping of related parts. The entire mechanism has a modular design and can be directly used in bundling machines, making it widely applicable.

[0007] A lithium battery bundling clamping mechanism according to an embodiment of the present invention includes: A first support is provided, on which an upper pressure mechanism is installed for pressing and shaping the upper part of the lithium battery module. A bidirectional lead screw, which is rotatably mounted on the first bracket; The clamping assembly has two components, which are symmetrically mounted on the bidirectional lead screw and can move synchronously in opposite or opposite directions along the axial direction of the bidirectional lead screw. A power mechanism is mounted on the first bracket, and the output end of the power mechanism is connected to the bidirectional lead screw to drive the bidirectional lead screw to rotate. The clamping assembly is used to fix and position the lithium battery module, and to press the shaped lithium battery module.

[0008] According to an embodiment of the present invention, a lithium battery bundling clamping mechanism can achieve synchronous clamping and positioning of lithium battery modules on both sides through the cooperation of components such as a first bracket, a bidirectional lead screw, clamping components, and a power mechanism. Compared with single-sided clamping, synchronous clamping on both sides ensures that the force on both sides is consistent and uniform during the positioning and clamping process, avoiding the situation where the lithium battery module bursts due to uneven force on both sides. Moreover, the distance between the two clamping components is adjustable, so the clamping mechanism can achieve positioning and clamping of lithium battery modules of different thicknesses. The entire clamping mechanism has a simple structure, is easy to operate, and has high working efficiency. At the same time, the cooperation of components such as the clamping components and the upper pressure mechanism can achieve shaping of the left and right sides and the top and bottom sides of the upper lithium battery module.

[0010] In some embodiments of this utility model, an upper limit plate is also included. There are two upper limit plates, which are symmetrically installed below the first bracket and located on both sides of the upper shaping plate.

[0011] In some embodiments of this utility model, it further includes: The frame is a frame structure, and a mounting plate is provided on the top of the frame; A lifting module is mounted on the mounting plate, and the output end of the lifting module is connected to the top of the first bracket; The first bracket, the bidirectional lead screw, and the clamping assembly are all arranged inside the frame.

Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] The following is for reference. Figures 1-7 The lithium battery bundling clamping mechanism 100 according to an embodiment of the present invention includes a first bracket 10, a bidirectional lead screw 20, a clamping assembly 30, and a power mechanism 40. The first bracket 10 is equipped with an upper pressing mechanism 50 for pressing and shaping the lithium battery module 500. The bidirectional lead screw 20 is rotatably mounted on the first bracket 10. There are two clamping assemblies 30, symmetrically mounted on the bidirectional lead screw 20, and capable of synchronously moving in opposite or opposing directions along the axial direction of the bidirectional lead screw 20. The power mechanism 40 is mounted on the first bracket 10, and its output end is connected to the bidirectional lead screw 20 to drive the bidirectional lead screw 20 to rotate. The clamping assembly 30 is used to fix and position the lithium battery module 500, and to press the shaped lithium battery module 500.

[0018] Specifically, the first support 10 can be a long strip with a U-shaped longitudinal section. The bidirectional lead screw 20 is arranged below the first support 10, and both ends of the bidirectional lead screw 20 are rotatably mounted on the first support 10 through bearing seats. The power mechanism 40 can be a bidirectional servo motor, fixedly mounted on one side of the first support 10, and its output end is connected to the end of the bidirectional lead screw 20. The clamping assembly 30 can include a slider mounted on the bidirectional lead screw 20 and a clamping part mounted on the slider. The clamping part cooperates with the lithium battery module 500 to be clamped. For example, the clamping part has three clamping rods: upper, middle, and lower. The two clamping assemblies 30 are positioned and clamped from the upper, middle, and lower parts of the lithium battery module 500. The slider is structured such that when the bidirectional lead screw 20 rotates, it moves along the axial direction of the bidirectional lead screw 20. When the bidirectional servo motor is working, the bidirectional lead screw 20 rotates under its drive, and the slider and the clamping part above it will move inward or outward simultaneously along the axial direction of the bidirectional lead screw 20, so as to realize the synchronous clamping and release of the lithium battery module 500 on both sides.

[0019] It should be noted that, under normal circumstances, the two clamping components 30 are located at both ends of the bidirectional lead screw 20, and the distance between them is greater than the size of the lithium battery module 500. When the bidirectional servo motor rotates in the forward direction, the clamping components 30 on the bidirectional lead screw 20 move synchronously in opposite directions to clamp and position the lithium battery module 500. Conversely, when the bidirectional servo motor rotates in the reverse direction, the clamping components 30 on the bidirectional lead screw 20 move synchronously outward in opposite directions to release the lithium battery module 500.

[0020] Understandably, during use, the lithium battery module 500 to be processed can be placed in the initial position, which is directly below the entire clamping mechanism 100, and the distance between the initial position and the two clamping components is equal to ensure uniform force on both sides during subsequent bidirectional synchronous clamping. Next, the first support 10 is controlled to move down until the two clamping components are at the same height as the lithium battery module 500. The bidirectional servo motor is then controlled to operate, and the bidirectional lead screw 10 will rotate accordingly. The two clamping components 30 simultaneously move inward along the axial direction of the bidirectional lead screw 20 in opposite directions until the lithium battery module 500 is clamped and positioned. Simultaneously with clamping, the clamping part can apply pressure to the lithium battery module 500, achieving pressure shaping of the clamping position. In view of this, the upper pressure mechanism 50 can also be controlled to operate. Since the lithium battery module 500 itself is placed on a tray, when the upper pressure mechanism 50 applies pressure to the lithium battery module 500 from top to bottom, it can achieve shaping of the top and bottom of the lithium battery module 500. The clamping mechanism, positioned at the top, middle, and bottom, exposes the part to be bundled, facilitating positioning and shaping before bundling. After shaping and bundling, the bidirectional servo motor can be controlled to work in reverse, and the bidirectional lead screw 20 also rotates in the opposite direction. The two clamping components 30 move outward along the axial direction of the bidirectional lead screw 20 in opposite directions, thereby releasing the lithium battery module 500.

[0021] According to an embodiment of the present invention, a lithium battery bundling clamping mechanism can achieve synchronous clamping and positioning of a lithium battery module 500 on both sides through the cooperation of components such as a first bracket 10, a bidirectional lead screw 20, a clamping assembly 30, and a power mechanism 40. Compared with single-sided clamping, synchronous clamping on both sides ensures that the force on both sides is consistent and uniform during the positioning and clamping process, avoiding the situation where the lithium battery module 500 bursts due to uneven force on both sides. Moreover, the distance between the two clamping assemblies 30 is adjustable, so the clamping mechanism can achieve positioning and clamping of lithium battery modules 500 of different thicknesses. The entire clamping mechanism has a simple structure, is easy to operate, and has high working efficiency. At the same time, the cooperation of components such as the clamping assembly 30 and the upper pressure mechanism 50 can achieve shaping of the left and right sides and the top and bottom sides of the upper lithium battery module 500. The entire mechanism has a modular design and can be directly used in a bundling machine.

[0022] In some embodiments of this utility model, reference is made to Figures 2 to 7 As shown, the upper pressure mechanism 50 may include an upper shaping plate 51 and a drive mechanism 52. The upper shaping plate 51 is horizontally arranged below the bidirectional lead screw 20 and located between the two clamping assemblies 30. The drive mechanism 52 is installed above the first bracket 10. The output end of the drive mechanism 52 passes through the first bracket 10 and is connected to the top of the upper shaping plate 51 to drive the upper shaping plate 51 to move up and down, thereby shaping the top of the lithium battery module 500.

[0023] For example, the upper shaping plate 51 is a rectangular plate, and four connecting rods 53 are symmetrically arranged on the upper surface of the rectangular plate. The four connecting rods 53 are installed in pairs on the rectangular plate, with the two connecting rods 53 on the left side forming one pair and the two connecting rods 53 on the right side forming another pair. The top ends of the two connecting rods 53 in the same pair are connected to a connecting plate, which is positioned above or below the first support 10. There are two drive mechanisms 52, both of which are electric cylinders. The two electric cylinders are symmetrically installed above the first support 10, and the movable end of each electric cylinder is connected to the upper surface of the connecting plate on the same side. By controlling the extension and retraction of the electric cylinders, the position of the rectangular plate can be adjusted. Under normal circumstances, the drive mechanism 52 is in the retracted state.

[0024] Understandably, the control drive mechanism 52 operates, causing the upper shaping plate 51 to move downwards under the action of the connecting plate and connecting rod, thereby applying pressure to the lithium battery module 500 in the tray from above, thus shaping the top and bottom of the lithium battery module 500. The entire structure is simple and easy to operate. Moreover, the symmetrical distribution of the connecting rod, electrician cylinder, etc., can improve the uniformity of force on the upper shaping plate 51, thereby achieving uniform pressure on the lithium battery module 500 and avoiding irregular shaping or even explosion caused by uneven force.

[0025] In some embodiments of this utility model, reference is made to Figures 2 to 7 As shown, it may also include an upper limit plate 90. There are two upper limit plates 90, which are symmetrically installed below the first bracket 10, located on both sides of the upper shaping plate 51. For example, the upper limit plate 90 has a U-shaped structure, is fitted onto the bidirectional lead screw 20, and its top end is connected to the bottom of the first bracket 10.

[0026] Understandably, the addition of the upper limit plate 90 can limit the positioning of the upper shaping plate 51; at the same time, it can also facilitate the installation of the bidirectional lead screw 20. Specifically, the bidirectional lead screw 20 can be placed in the recess of the upper limit plate 90 first, and then its end can be installed on the first bracket 10. The upper limit plate 90 can provide a certain support force for the bidirectional lead screw 20, which saves effort and makes installation more convenient.

[0027] In some embodiments of this utility model, reference is made to Figures 2 to 7As shown, it may also include a frame 60 and a lifting module 70. The frame 60 is a frame structure, and a mounting plate 61 is provided on the top of the frame 60. The lifting module 70 is mounted on the mounting plate 61, and the output end of the lifting module 70 is connected to the top of the first support 10. The first support 10, the bidirectional lead screw 20, and the clamping assembly 30 are all arranged inside the frame 60. For example, the entire frame 60 can be a frame mechanism composed of two horizontal bars 601, two vertical bars 602, and four uprights 603. The two horizontal bars 601 and two vertical bars 602 are arranged crosswise to form a rectangular frame, and the four uprights 603 are vertically installed at the four corners of the rectangular frame. The bottoms of two uprights 603 on the same side are connected by a fixing plate 604. The lifting module 70 can be an electric telescopic rod, which is vertically mounted on the mounting plate 61, and the movable end of the lifting module 70 is connected to the top of the first support 10.

[0028] It is understandable that the lifting module 70 allows the first support 10 to be movably installed within the frame 60, integrating the first support 10, clamping components 30, and other components with the frame 60. The lifting module 70 can adjust the height of the first support 10 and the clamping components 30 above it, thereby clamping and releasing the lithium battery module 500. Under normal circumstances, the lifting module 70 is in a retracted state, with the first support 10 and clamping components 30 positioned above, not affecting the lateral movement of the lithium battery module 500 below. After the lithium battery module 500 moves to its initial position, the lifting module 70 is extended, causing the first support 10 and clamping components 30 to move downwards, positioning the two clamping components 30 on either side of the lithium battery module 500. Next, the power mechanism 40 is activated to clamp and position the lithium battery module 500. The upper pressure mechanism 50 is then activated to shape the top and bottom of the lithium battery module 500. The overall structure is simple and efficient.

[0029] To improve the stability of the first support 10 and clamping assembly 30 during vertical movement, some embodiments of this invention may include a guide assembly 80. The guide assembly 80 may include a guide cylinder 81 and a guide rod 82. The guide cylinder 81 is mounted on the mounting plate 61; the guide rod 82 is movably mounted inside the guide cylinder 81, with one end of the guide rod 82 away from the guide cylinder 81 connected to the top of the first support 10. Multiple guide assemblies 80 may be symmetrically arranged on the mounting plate 61. For example, there may be four sets of guide assemblies 80, with four guide cylinders 81 symmetrically mounted on the mounting plate 61, the top ends of the four guide rods 82 correspondingly installed and removed from the guide cylinders 81, and the bottom ends of the four guide rods 82 connected to the first support 10. The lifting module 70 is located at the midpoint of the intersecting line connecting the four guide cylinders 81. When the lifting module 70 is working, the guide rods 82 can move vertically downwards or upwards synchronously. In other words, the lifting module 70 is connected to the middle of the first bracket 10, and four guide components 80 are distributed around the lifting module 70. The distance between each guide component 80 and the lifting module 70 is the same, realizing the connection from the mounting plate 61 to the middle and the surrounding parts of the first bracket 10. The four guide rods 82 can work synchronously with the lifting module, ensuring the stability of the up and down movement of the first bracket 10 and clamping components 30.

[0030] Reference Figures 2 to 7 As shown, a lithium battery bundling machine 1000 according to an embodiment of the present invention includes a machine base 200, a clamping assembly and a bundling mechanism 300. The clamping assembly is the clamping mechanism 100 described above. The clamping mechanism 100 is mounted on the machine base 200. The bundling mechanism 300 is used to bundle the lithium battery module 500 clamped in the clamping mechanism 100.

[0031] For example, the machine base 200 is provided with feeding, shaping and pressing, and bundling positions. The clamping mechanism 100 is installed on the machine base 200, and the initial position of the clamping mechanism 100 corresponds to the feeding, shaping and pressing, and bundling positions. The bundling mechanism 300 can adopt existing commonly used bundling mechanisms. Its specific structure is not the focus of protection of this utility model, so it will not be described in detail here.

[0032] To improve work efficiency, a conveying mechanism 400 penetrating the frame 60 can be installed on the machine base 200. The conveying mechanism has multiple equally spaced mounting seats for storing lithium battery modules 500. Each mounting seat has a movable plate on which the lithium battery modules 500 are placed. Correspondingly, a lifting mechanism is installed on the machine base 200, directly below the clamping mechanism 100. When the conveying mechanism 400 operates, and one of the mounting seats carrying the lithium battery module 500 moves to directly below the lifting mechanism, the lifting mechanism starts working, lifting the movable plate on the mounting seat. Simultaneously, the lithium battery module 500 above it moves upward to its initial position, facilitating subsequent positioning, clamping, and bundling operations. It should be noted that the conveying mechanism 400 can adopt a common structure consisting of existing conveying rails and a drive mechanism. The conveying rail is arranged on the machine base, penetrating the frame 60, enabling continuous conveying. Of course, the conveying mechanism 400 is equipped with corresponding sensor detection equipment to ensure the accuracy of the lithium battery module 500 during conveying.

[0033] Understandably, before use, all components should be installed on the machine base 200 according to the above instructions. All relevant components, including the power mechanism, drive mechanism, lifting mechanism, and lifting module, should be in the retracted state to ensure the equipment is safe and ready before operation. Next, the conveying mechanism 400 is controlled to operate. When the lithium battery module 500 is moved directly above the lifting mechanism, the lifting mechanism is controlled to lift the movable plate along with the lithium battery module 500 above it to its initial position. The lifting module 70 is controlled to operate, causing the first support 10 to move downwards until the clamping assembly 30 moves to the left and right sides of the lithium battery module 500. The upper pressure mechanism 50 is controlled to operate, achieving shaping and pressure application to the top and bottom of the lithium battery module 500; after completing the corresponding shaping and pressure application, the upper pressure mechanism 50 is controlled to reset. The power mechanism 40 is controlled to operate, and the two clamping components 30 move inward simultaneously to clamp the lithium battery module 500. After clamping, the binding mechanism 300 can be controlled to operate to bind the lithium battery module 500. Finally, the power mechanism 40 can be controlled to release the bound lithium battery module 500, and the lifting mechanism can be controlled to retract. The movable plate will carry the lithium battery module 500 down to the mounting seat of the conveying mechanism 400. As the conveying mechanism 400 is transported to the outside of the machine 200 along its track, the lithium battery module 500 on the conveying mechanism 400 undergoes the above-mentioned lifting, shaping, clamping, and binding operations in sequence, improving the working efficiency of the entire device.

[0034] In summary, this utility model, through the cooperation of various components, realizes the feeding, shaping, pressing, and bundling operations of the lithium battery module 500. The clamping mechanism 100 adopts a bidirectional synchronous clamping method, which provides more even force on both sides compared to single-sided clamping, avoiding the possibility of explosion due to uneven force. The cooperation of various pressurizing mechanisms can achieve shaping and pressurizing of corresponding parts, which is simple to operate and highly controllable. Combining the conveying mechanism with the clamping mechanism further improves work efficiency.
