Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing and automated assembly technology, specifically to a movable positioning mechanism for a stacking platform. Background Technology

[0002] In the field of battery manufacturing and automated assembly, the stacking positioning accuracy and assembly stability of battery modules directly affect product performance and production efficiency. Battery modules are usually composed of multiple cells, end plates and packaging components. The stacking process requires precise alignment of the end plates and cells, stable clamping of the modules, and adaptation to different specifications (number of cells, size) of production requirements.

[0003] However, existing stacking positioning devices still have shortcomings:

[0004] 1. The positioning structure has poor adaptability and is mostly designed with fixed size. When the battery module specifications change, the entire stacking tooling needs to be replaced or the core components need to be adjusted, which is cumbersome and has high adaptation costs.

[0005] Second, the coordination between power drive and guide structure is insufficient. Some equipment relies on a single power source to move the tooling, lacking stable guide and limit, which makes the tooling easy to deviate during operation, resulting in misalignment between the battery cell and the end plate, affecting the structural rigidity of the module after packaging.

[0006] Third, the positioning and connection stability is poor. There is no reliable positioning and matching structure between the tooling and the end plate. During the stacking process, the module is easily shaken by external forces, making it difficult to ensure the accurate implementation of subsequent steel strip binding, packaging and other processes, which ultimately affects the finished product quality and service life of the battery module.

[0007] To address this, a movable positioning mechanism for stacking platforms is proposed. Summary of the Invention

[0008] The purpose of this invention is to provide a movable positioning mechanism for a stacking platform to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a stacking platform positioning mechanism, comprising a worktable, a moving end running component and a positioning end running component, wherein the moving end running component and the positioning end running component are symmetrically arranged on both sides of the worktable, and two stacking fixtures are symmetrically installed on the side adjacent to the moving end running component and the positioning end running component, and a battery module is provided on the worktable and on the side adjacent to the two stacking fixtures.

[0010] The active end running component includes a mounting base and a reduction gearbox. Two movable rods symmetrically pass through the mounting base, and a servo motor and a hydraulic cylinder are respectively mounted on the reduction gearbox.

[0011] As a further preferred embodiment of this technical solution: the stacking fixtures and battery modules are supported by a worktable, while the moving end running component is used to provide power output and ensure movement stability. At the same time, the positioning end running component is used to drive the corresponding side stacking fixtures to move precisely.

[0012] As a further preferred embodiment of this technical solution: the hydraulic cylinder is located on one side adjacent to the two movable rods, the side of the hydraulic cylinder away from the gearbox is connected to the mounting base, and the piston rod of the hydraulic cylinder passes through the mounting base.

[0013] In this configuration, the ends of the two movable rods and the hydraulic cylinder piston rods away from the reduction gearbox are each connected to a stacking fixture. The operation of the hydraulic cylinder drives the stacking fixture connected to it to move horizontally.

[0014] As a further preferred embodiment of this technical solution: the positioning end running component includes a second mounting base, in which two connecting rods are symmetrically connected. One end of each connecting rod is fixedly connected to a connecting plate, and a receiving plate is fixedly connected to the connecting plate. A cylinder is mounted on the receiving plate. The connecting rods and lead screw are supported by the second mounting base, while the cylinder is supported by the receiving plate. At the same time, the cylinder moves horizontally through each connecting block.

[0015] As a further preferred embodiment of this technical solution: the cylinder piston rod is equipped with a connecting block one, the bottom of the connecting block one is equipped with a connecting plate, and one end of the connecting block one is equipped with a connecting block two;

[0016] Both connecting rods pass through the connecting plate. The cylinder drives connecting block one, which connects to connecting block two, thus linking connecting block two. Since connecting block two is connected to the mounting plate, the mounting plate moves horizontally.

[0017] As a further preferred embodiment of this technical solution: the end of the second connecting block away from the first connecting block is equipped with an installation plate, and the ends of the two connecting rods away from the connecting plate are both inserted into the installation plate. The side of the installation plate away from the connecting plate is connected to another stacking fixture, and the stacking fixture is connected through the installation plate.

[0018] As a further preferred embodiment of this technical solution: the positioning end running component further includes a lead screw, which passes through the connecting plate, the second mounting base, the connecting plate, and the mounting plate in sequence;

[0019] The lead screw is installed with a crank handle on the extension section through the connecting plate. The crank handle rotates the lead screw to move each plate component, thereby adjusting the distance between the positioning end stacking fixture and the moving end stacking fixture.

[0020] As a further preferred embodiment of this technical solution: the battery module includes multiple battery cells and two end plates. The multiple battery cells are located on the adjacent side of the two end plates, and steel strips and packing straps are respectively installed on the opposing side of the two end plates and on the outside of the multiple battery cells. The two end plates are set to support and protect the multiple battery cells inside, as well as for positioning, fitting and connecting. The steel strips improve the structural rigidity of the battery module, while the packing straps assist in tight sealing and adapting to the module shape.

[0021] As a further preferred embodiment of this technical solution: two pins are symmetrically fixedly connected to each of the two stacked fixtures on adjacent sides, and two through holes are symmetrically opened on each of the two end plates on opposing sides;

[0022] The pin passes through the through hole. The above-mentioned arrangement is used for precise positioning between the battery module and the stacking fixture, and for stable connection between the battery module and the stacking fixture.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The positioning end running component of this utility model is equipped with a lead screw and a crank. Turning the crank can drive the lead screw to adjust the spacing between the positioning end and the moving end stacking fixture. Without replacing the entire set of fixtures or core components, it can be adapted to battery modules with different numbers and sizes of cells. The servo motor of the moving end component, together with the gearbox, can accurately adjust the power output, and the hydraulic cylinder provides sufficient thrust, further adapting to diverse production needs. It is easy to operate and greatly reduces the adaptation cost.

[0025] 2. In this utility model, the two movable rods at the movable end and the piston rod of the hydraulic cylinder form a three-point support, which limits the movement trajectory of the stacked tooling. The two connecting rods at the positioning end play a stable guiding role in the movement of the connecting plate and the mounting plate. Both ends have reliable guiding limits. With the precise power drive of the servo motor and the cylinder, it effectively prevents the tooling from deviating during operation, avoids misalignment between the battery cell and the end plate, and ensures the structural rigidity of the module after packaging.

[0026] 3. In this utility model, the pins of the stacking fixture and the through holes of the battery module end plate are precisely matched to achieve stable connection and positioning between the two, avoiding the module from shaking due to external forces during the stacking process. At the same time, the steel strip increases the structural rigidity and the packing strap assists in tight sealing during module packaging, ensuring that the subsequent bundling and packaging processes are accurately implemented, reducing finished product quality problems and extending the service life of the battery module.

[0027] 4. In this utility model, the mechanism can quickly complete the initial spacing adjustment through the crank handle, the dual-end power components drive the tooling to move efficiently, the tooling and module positioning connection is convenient, and the tooling can be quickly separated from the module after packaging. The overall operation steps are smooth and continuous, reducing manual operation time and complexity, and effectively improving the production efficiency of battery module stacking and assembly.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0036] Example

[0037] Please see Figures 1-6 The present invention provides a technical solution: a stacking platform positioning mechanism, including a workbench 1, a moving end running component 2 and a positioning end running component 3. The moving end running component 2 and the positioning end running component 3 are symmetrically arranged on both sides of the workbench 1. Two stacking fixtures 4 are symmetrically installed on the side adjacent to the moving end running component 2 and the positioning end running component 3. A battery module 5 is provided on the workbench 1 and on the side adjacent to the two stacking fixtures 4.

[0038] The active end running component 2 includes a mounting base 21 and a reduction gearbox 23. Two movable rods 22 are symmetrically inserted through the mounting base 21. A servo motor 24 and a hydraulic cylinder 25 are respectively installed on the reduction gearbox 23.

[0039] In this embodiment, specifically: the workbench 1 is used to support the stacking fixture 4 and the battery module 5, while the movable end running component 2 is used to provide power output and ensure movement stability. At the same time, the positioning end running component 3 is used to drive the corresponding side stacking fixture 4 to move precisely, so as to achieve stable clamping (providing multiple power drives), precise positioning and adaptation adjustment of the battery module 5.

[0040] In this embodiment, specifically: the servo motor 24 can adjust the power output accuracy through the reduction gearbox 23 to achieve smooth and controllable movement of the tooling, while the hydraulic cylinder 25 can provide sufficient thrust to ensure that the clamping force of the tooling on the battery module 5 meets the standard, thereby adapting to the stacking requirements of different specifications of battery cells 51. At the same time, the two movable rods 22 and the piston rod of the hydraulic cylinder 25 are connected to the same stacking tooling 4, thereby forming a three-point support structure, which effectively restricts the movement trajectory of the stacking tooling 4, avoids it from deviating or shaking during operation, and ensures that the tooling always moves smoothly towards or away from the battery module 5 in a preset direction.

[0041] In this embodiment, specifically: the hydraulic cylinder 25 is located on the adjacent side of the two movable rods 22, the side of the hydraulic cylinder 25 away from the reduction gearbox 23 is connected to the mounting base 21, and the piston rod of the hydraulic cylinder 25 passes through the mounting base 21;

[0042] Among them, the two movable rods 22 and the piston rod of the hydraulic cylinder 25 are all connected to a stacking fixture 4 at the end away from the reduction gearbox 23. With the above configuration, the hydraulic cylinder 25 drives the stacking fixture 4 connected to it to move horizontally.

[0043] In this embodiment, specifically: the positioning end running component 3 includes a second mounting base 31, with two connecting rods 32 symmetrically passing through the second mounting base 31. A connecting plate 34 is welded to one end of each of the two connecting rods 32, and a receiving plate 35 is welded to the connecting plate 34. A cylinder 36 is mounted on the receiving plate 35. The second mounting base 31 is used to support the connecting rods 32 and the lead screw 33, while the receiving plate 35 is used to support the cylinder 36. At the same time, the cylinder 36 moves horizontally through each connecting block to achieve the horizontal movement of the mounting plate 310.

[0044] In this embodiment, specifically: the piston rod of cylinder 36 is equipped with a connecting block 37, the bottom of the connecting block 37 is equipped with a connecting plate 38, and one end of the connecting block 37 is equipped with a connecting block 39.

[0045] Both connecting rods 32 pass through the connecting plate 38. With the above arrangement, when the cylinder 36 runs, it drives the connecting block 37. The connecting block 37 is connected to the connecting block 39, so that the connecting block 39 is linked. At this time, because the connecting block 39 is connected to the mounting plate 310, the mounting plate 310 can move horizontally.

[0046] It should be further explained that the moving distance of the mounting plate 310 is the distance between the mounting plate 310 and the connecting plate 38.

[0047] In this embodiment, specifically: a mounting plate 310 is installed on the end of the connecting block 2 39 away from the connecting block 1 37, and the ends of the two connecting rods 32 away from the connecting plate 34 are both inserted into the mounting plate 310. The side of the mounting plate 310 away from the connecting plate 38 is connected to another stacking fixture 4. The mounting plate 310 is used to connect the stacking fixture 4.

[0048] In this embodiment, specifically: the positioning end running component 3 also includes a lead screw 33, which passes through the connecting plate 34, the second mounting base 31, the connecting plate 38 and the mounting plate 310 in sequence;

[0049] The lead screw 33 is connected to the extension of the connecting plate 34 and a crank is installed. By rotating the lead screw 33 through the crank, the various plate components can be moved, thereby adjusting the distance between the positioning end stacking fixture 4 and the moving end stacking fixture 4. This allows for the adjustment and adaptation of battery modules 5 with different sizes and different numbers of cells 51. It can meet diverse production needs without replacing core components, thus improving the adaptability and practicality of the mechanism.

[0050] In this embodiment, specifically: the battery module 5 includes multiple battery cells 51 and two end plates 52. The multiple battery cells 51 are located on the adjacent side of the two end plates 52. The two end plates 52 are located on the opposing side and on the outside of the multiple battery cells 51, respectively, with steel strips 53 and packing straps 54 installed. The two end plates 52 are used to support and protect the multiple battery cells 51 inside, and to position and connect them. The steel strips 53 are used to improve the structural rigidity of the battery module 5, thereby resisting external impact and preventing the multiple battery cells 51 from deforming or shifting due to external forces. At the same time, the packing straps 54 are used to assist in tight sealing and adapt to the module shape.

[0051] It is worth further elaborating that the steel strip 53 and the packing strap 54 prevent the module from becoming structurally loose after long-term use, ensuring the stability of the arrangement of multiple cells 51, thus providing a structural foundation for the subsequent precise docking with the stacking fixture 4.

[0052] In this embodiment, specifically: two stacked fixtures 4 are symmetrically integrally formed with two pins 41 on adjacent sides, and two end plates 52 are symmetrically provided with two through holes 521 on opposing sides.

[0053] Among them, pin 41 passes through the through hole 521.

[0054] In this embodiment, specifically: the above settings are used for precise positioning between the battery module 5 and the stacking fixture 4, effectively limiting the horizontal displacement of the battery module 5 on the workbench 1 (such as left, right, front, or back offset), thereby ensuring that the battery module 5 can be accurately within the working range of the active end running component 2 and the positioning end running component 3, thus providing an accurate reference for subsequent stacking, fixing and other processes. On the other hand, it is used for stable connection between the battery module 5 and the stacking fixture 4, forming a temporary "locked" state between the battery module 5 and the stacking fixture 4, preventing the battery module 5 from shaking or misaligning due to force when the active end running component 2 or the positioning end running component 3 is working, thereby ensuring the stability of the entire positioning and stacking process.

[0055] Working principle: According to the size and specifications of the battery module 5 to be stacked, the screw 33 in the positioning end running component 3 is rotated by the crank handle, which sequentially drives the connecting plate 34, the connecting plate 38, the mounting plate 310 and the connected stacking fixture 4 to move, adjusting the initial distance between the positioning end and the stacking fixture 4 on both sides of the moving end, so as to adapt to the number of battery cells 51 and the size of the end plate 52, providing basic adaptation conditions for subsequent stacking operations.

[0056] The cylinder 36 of the positioning end running component 3 is activated. The piston rod of the cylinder 36 extends and drives the connecting block 1 37 and the connecting block 2 39 to move together. The connecting plate 38 slides along the connecting rod 32, thereby pushing the mounting plate 310 and the connected stacking fixture 4 to move towards the center of the worktable 1 to the foremost position. At this time, the first end plate 52 is placed on the positioning end stacking fixture 4. The pin 41 on the fixture passes through the through hole 521 of the end plate 52, so as to achieve accurate positioning and stable connection between the end plate 52 and the positioning end fixture.

[0057] On the end plate 52 that has been fixed at the positioning end, the battery cells 51 with glue or double-sided adhesive applied to the surface are stacked in sequence according to the process requirements. After the battery cells 51 are stacked, the second end plate 52 is placed on the movable end stacking fixture 4. Similarly, the positioning connection between the end plate 52 and the movable end fixture is achieved by the cooperation of the pin 41 and the through hole 521.

[0058] The servo motor 24 of the active end running component 2 is started. After the power output accuracy of the servo motor 24 is adjusted by the reduction gearbox 23, it drives the hydraulic cylinder 25 to run. The piston rod of the hydraulic cylinder 25 pushes the active end stacking fixture 4 to move towards the positioning end along the guide direction of the two active rods 22, applying a preset pressure to the second end plate 52 and the internal battery cell 51, so that the battery module 5 is compressed to the set length. In this state, the staff puts the steel belt 53 on the module and attaches the packing strap 54. The steel belt 53 increases the rigidity of the module structure, and the packing strap 54 assists in tight sealing to ensure the stable arrangement of the battery cells 51.

[0059] After the module is packaged, the piston rod of the movable end hydraulic cylinder 25 retracts, driving the movable end stacking fixture 4 away from the module and relieving the pressure on the module. At the same time, the piston rod of the positioning end cylinder 36 retracts, pulling the mounting plate 310 and the positioning end stacking fixture 4 backward through the connecting block 1 37 and the connecting block 2 39, so that the pin 41 on the fixture separates from the through hole 521 of the end plate 52. After both fixtures are separated from the module, the stacked battery module 5 can be easily taken out and enter the next production process.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
