Description

Technical Field

[0001] The present invention relates to the technical field of battery core manufacturing, in particular to a multi-station battery core clamping workstation. Background Art

[0002] Amid the rapid development of the new energy industry, lithium batteries, as core energy storage components, face a significant impact on product quality and efficiency through the automation and refinement of their manufacturing. Cell clamping, a critical process in lithium battery assembly, requires ensuring precise positioning while also avoiding surface damage and enabling efficient multi-station collaboration.

[0003] As far as the current status of the industry is concerned, the traditional battery cell clamping workstation has the following main technical bottlenecks: 1) It uses a rigid mechanical structure for positioning, which can easily cause irreversible damage such as scratches and deformation to the surface of the battery cell during the pushing process. Especially when processing ultra-thin, high-energy-density battery cells, the yield rate is significantly reduced, and it is easy to cause damage to the outer shell or puncture the internal diaphragm, which in turn causes safety hazards such as battery short circuits; 2) In a single-station or asynchronous operation mode, the position of each battery cell needs to be adjusted one by one, which will inevitably lead to a long clamping cycle and make it difficult to meet the efficiency requirements of large-scale production. Even if a multi-station asynchronous operation mode is adopted, since the clamping actions of each station are isolated, there is still a lot of waiting time between processes, and the overall production efficiency improvement is limited; 3) The battery cell clamping workstation has poor versatility, that is, when facing battery cells of different sizes and specifications, a large number of limiting components and side push components need to be redesigned or replaced, the transformation cost is high, and the implementation cycle is long. Therefore, it is urgent for technical personnel in this field to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-station battery cell clamping workstation that has the advantages of high-precision positioning, flexible protection, and efficient multi-station collaboration, so as to solve the problems existing in the prior art.

[0005] The present invention relates to a multi-station battery cell clamping workstation comprising N side-by-side positioning jigs, an X-direction pusher, and a Y-direction pusher, where N is greater than or equal to 2. After the N battery cells are placed one by one relative to the positioning jig, their X-direction positions are adjusted due to the X-direction non-rigid lateral thrust from the X-direction pusher, and their Y-direction positions are adjusted due to the Y-direction non-rigid lateral thrust from the Y-direction pusher.

[0006] As a further improvement to the technical solution disclosed in the present invention, the spacing between the N positioning fixtures is a. The X-direction pushing portion includes a load-bearing linear motion element, an X-direction pushing linear motion element, an X-direction primary elastic buffer module, a load-bearing beam, and N X-direction secondary elastic buffer modules. The X-direction pushing linear motion element and the X-direction primary elastic buffer module are both carried by the load-bearing linear motion element. The load-bearing beam is carried by the X-direction primary elastic buffer module. The N X-direction secondary elastic buffer modules are all mounted on the load-bearing beam and are spaced apart by a distance b, where b = a. The load-bearing linear motion element performs work, and the N X-direction secondary elastic buffer modules synchronously perform Y-direction displacement motion until they are aligned with the positioning fixture; the X-direction pushing linear motion element performs work, and the N X-direction secondary elastic buffer modules synchronously approach the battery cell opposite to it; after any battery cell is positioned in the X direction, the X-direction secondary elastic buffer module opposite to it stores elastic potential energy due to compression. At the same time, the X-direction primary elastic buffer module synchronously stores elastic potential energy due to compression, until the remaining battery cells are positioned in the X direction one by one. During this process, the X-direction secondary elastic buffer module opposite to it stores elastic potential energy due to compression, and the elastic potential energy stored in the X-direction primary elastic buffer module gradually increases.

[0007] As a further improvement of the technical solution disclosed in the present invention, the X-direction primary elastic buffer module includes a first X-direction primary sliding member, a second X-direction primary sliding member and an X-direction primary elastic coupling assembly. The first X-direction primary sliding member is directly pushed by the X-direction push linear motion element. The second X-direction primary sliding member is used as the installation base of the load-bearing beam. The X-direction primary elastic coupling assembly is assembled between the first X-direction primary sliding member and the second X-direction primary sliding member. During the work of the X-direction push linear motion element, the first X-direction primary sliding member performs translational motion due to the direct side thrust, the X-direction primary elastic coupling assembly synchronously stores elastic potential energy, and the second X-direction primary sliding member performs translational motion due to the elastic side thrust from the X-direction primary elastic coupling assembly.

[0008] As a further improvement to the technical solution disclosed in this invention, the X-direction primary elastic coupling assembly comprises an X-direction primary guide member and an X-direction primary elastic member. The X-direction primary guide member is inserted into the first X-direction primary sliding member and extends in the X direction through the second X-direction primary sliding member. The X-direction primary elastic member is elastically compressed between the first and second X-direction primary sliding members.

[0009] As a further improvement of the technical solution disclosed in the present invention, the X-direction pushing top portion further includes an X-direction guide assembly. With the help of the guiding force of the X-direction guide assembly, the first X-direction primary sliding member and the second X-direction primary sliding member can achieve directional translation movement.

[0010] As a further improvement to the technical solution disclosed in the present invention, the X-direction guide assembly includes an X-direction slide rail, a first X-direction slider, and a second X-direction slider. The first X-direction slider and the second X-direction slider are detachably fixed to the bottom walls of the first X-direction primary sliding member and the second X-direction primary sliding member, respectively, in a one-to-one correspondence.

[0011] As another modified design scheme, the X-direction primary elastic coupling assembly can also preferably be composed of M X-direction primary spring members arranged side by side and elastically compressed between the first X-direction primary sliding member and the second X-direction primary sliding member.

[0012] As a further improvement to the technical solution disclosed herein, the X-direction secondary elastic buffer module includes an X-direction mounting base, an X-direction side thrust plate, and an X-direction secondary elastic coupling assembly. The X-direction mounting base is mounted on a load-bearing beam. The X-direction side thrust plate is used to directly push up the battery cells. The X-direction secondary elastic coupling assembly is assembled between the X-direction mounting base and the X-direction side thrust plate. As the X-direction side thrust plate pushes the battery cells laterally, the X-direction secondary elastic coupling assembly is compressed, storing elastic potential energy.

[0013] As a further improvement to the technical solution disclosed herein, the number of X-direction secondary elastic coupling assemblies is M, arranged side by side, with M ≥ 2. The X-direction secondary elastic coupling assemblies comprise an X-direction secondary guide member and an X-direction secondary elastic member. The X-direction secondary guide member is inserted into the X-direction mounting base plate and extends through the X-direction side thrust plate in the X-direction direction. The X-direction secondary elastic member fits over the X-direction secondary guide member and is elastically compressed between the X-direction mounting base plate and the X-direction side thrust plate.

[0014] As a further improvement to the technical solution disclosed in the present invention, the Y-direction pushing portion is composed of N Y-direction pushing mechanisms arranged side by side. The Y-direction pushing mechanism includes a Y-direction pushing linear motion element, a Y-direction elastic buffer module, and a Y-direction side thrust member. The Y-direction elastic buffer module is driven by the Y-direction pushing linear motion element and is used to support the Y-direction side thrust member. While the Y-direction pushing linear motion element is working, the Y-direction side thrust member approaches and laterally pushes the battery cell until the battery cell is positioned in the Y direction. During this process, the Y-direction elastic buffer module is compressed, storing elastic potential energy.

[0015] In practical applications, the multi-station battery cell clamping workstation disclosed in the present invention can achieve at least the following beneficial technical effects, specifically:

[0016] 1) By applying non-rigid lateral thrust to the sidewalls through the X- and Y-direction pushers, the battery cell can be adjusted in the X and Y directions. This effectively prevents irreversible damage to the cell surface, such as scratches and deformation. This is especially true for ultra-thin, high-energy-density cells with fragile outer shells. This prevents outer shell damage or puncture of the internal diaphragm, significantly reducing the risk of safety hazards such as battery short circuits and ensuring the safety of the battery cell during the clamping process.

[0017] 2) Multiple positioning fixtures are placed side by side, and the X-axis push-top and Y-axis push-top are coordinated to achieve the simultaneous clamping and adjustment of multi-station battery cells, which can significantly reduce the total clamping operation time. In large-scale production, it can effectively reduce the waiting time between processes, meet the production line requirements for efficient battery clamping, and ensure the efficient and continuous operation of the production line;

[0018] 3) The multi-station layout and bidirectional push-up structure design give the multi-station battery cell clamping workstation excellent parameter adjustment and adaptability, making it suitable for a variety of battery cell sizes and specifications. That is, when faced with battery cells of different sizes and specifications, by adjusting the force stroke of the X- and Y-axis push-up tops, the layout spacing of the positioning fixture, and other parameters, it can be quickly adapted to various types of battery cells without the need for redesign or large-scale replacement of components.

DETAILED DESCRIPTION

[0031] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 、 Figure 2 The three-dimensional schematic diagrams of the multi-station battery clamping workstation disclosed in the present invention from two different perspectives are shown. It can be seen that it is mainly composed of several parts such as a positioning fixture 1, an X-direction pushing top 2 and a Y-direction pushing top 3. Among them, the positioning fixture 1 is used to carry the battery cells to be clamped, the number of which is 2 and arranged in parallel along the X direction. The positioning fixture 1 includes a fixture body 11 and an "L-shaped" limiting member 12. The limiting member 12 is placed and fixed on the top wall of the fixture body 11 (such as Figure 3(as shown in ). The X- and Y-direction pushers 2 and 3 provide lateral thrust for positioning the cells. After the two cells are placed onto the positioning jig 1, the X-direction pusher 2 applies a non-rigid lateral thrust in the X direction to propel the cells until they contact the X-direction limit surface of the limiter 12, completing the X-direction position adjustment. Simultaneously, the Y-direction pusher 3 applies a non-rigid lateral thrust in the Y direction to propel the cells until they contact the Y-direction limit surface of the limiter 12, completing the Y-direction position adjustment.

[0032] like Figure 4 、 Figure 5 As shown in , the X-direction pushing part 2 includes a bearing linear motion element 21, an X-direction pushing linear motion element 22, an X-direction first-level elastic buffer module 23, a bearing beam 24, and two X-direction second-level elastic buffer modules 25. Among them, the X-direction pushing linear motion element 22 and the X-direction first-level elastic buffer module 23 are both carried by the bearing linear motion element 21. The bearing beam 24 is carried by the X-direction first-level elastic buffer module 23. The two X-direction second-level elastic buffer modules 25 are both installed on the bearing beam 24 and are separated by a set distance b. Figure 1 As shown in , the distance between the two positioning fixtures 1 is a, then b=a.

[0033] In actual application, the load-bearing linear motion element 21 is started first, and the load-bearing beam 24 drives the two X-direction secondary elastic buffer modules 25 to synchronously perform Y-direction displacement movement until the alignment with the positioning fixture 1 is completed; then, the X-direction pushing linear motion element 22 performs work, and the two X-direction secondary elastic buffer modules 25 synchronously approach the battery cells opposite to it; when any battery cell completes the top contact with the X-direction limit surface of the limit member 12, the X-direction secondary elastic buffer module 25 opposite to it stores elastic potential energy due to compression. At the same time, the X-direction primary elastic buffer module 23 synchronously stores elastic potential energy due to compression until the other battery cell completes the top contact with the X-direction limit surface of the other limit member 12, and in this process, the X-direction secondary elastic buffer module 25 opposite to it stores elastic potential energy due to compression, and the elastic potential energy stored by the X-direction primary elastic buffer module 23 gradually increases.

[0034] By adopting the above-mentioned technical solution, on the one hand, the X-direction primary elastic buffer module 23 and the X-direction secondary elastic buffer module 25 cooperate to form a two-stage elastic buffer structure. During the battery cell positioning process, when any battery cell first completes the top contact, the X-direction secondary elastic buffer module 25 is first compressed to provide initial buffering, effectively preventing the battery cell from being damaged by rigid impact. At the same time, the X-direction primary elastic buffer module 23 is synchronously compressed to absorb residual energy and provide a continuous and stable positioning force. On the other hand, the load-bearing linear motion element 21 is used to achieve the Y-direction synchronous displacement of the two X-direction secondary elastic buffer modules 25, so that they can quickly and accurately align with the positioning fixture 1. Then, the X-direction push linear motion element 22 is used to synchronously drive the two X-direction secondary elastic buffer modules 25 to push the battery cell, realizing dual-station parallel operation.

[0035] More importantly, when there are dimensional tolerances or positioning deviations between the two battery cells, the elastic potential energy stored in the primary elastic buffer module 23 and the X-direction secondary elastic buffer module 25 can be dynamically adjusted. For example, when the X-direction secondary elastic buffer module 25 corresponding to the battery cell that has been positioned first stops compressing, the primary elastic buffer module 23 continues to compress and increase its potential energy, pushing the other X-direction secondary elastic buffer module 25 to continue pushing until the other battery cell is positioned, ensuring that all battery cells can meet high-precision positioning requirements.

[0036] like Figure 6 As shown in FIG, the X-direction primary elastic buffer module 23 includes a first X-direction primary sliding member 231, a second X-direction primary sliding member 232, and an X-direction primary elastic coupling assembly 233. The first X-direction primary sliding member 231 is directly pushed by the X-direction push linear motion element 22. The second X-direction primary sliding member 232 serves as the mounting base for the load-bearing beam 24. The X-direction primary elastic coupling assembly 233 is assembled between the first X-direction primary sliding member 231 and the second X-direction primary sliding member 232. The X-direction primary elastic coupling assembly 233 is composed of an X-direction primary guide 2331 and an X-direction primary elastic member 2332. The X-direction primary guide 2331 is inserted into the first X-direction primary sliding member 231 and extends through the second X-direction primary sliding member 232 in the X direction. The X-direction primary elastic member 2332 is elastically compressed between the first X-direction primary sliding member 231 and the second X-direction primary sliding member 232.

[0037] During the work of the X-direction pushing linear motion element 22, the first X-direction primary sliding member 231 performs translational motion due to the direct side thrust, and the X-direction primary elastic member 2332 synchronously stores elastic potential energy. The second X-direction primary sliding member 232 performs translational motion due to the elastic side thrust from the X-direction primary elastic member 2332, effectively avoiding the impact force directly acting on the battery cell, thereby reducing the risk of scratches and deformation of the battery cell due to rigid contact.

[0038] Furthermore, the first X-direction first-level sliding member 231 and the second X-direction first-level sliding member 232 are separated from each other, so that the X-direction first-level elastic buffer module 23 is endowed with flexible displacement adjustment capability. In this way, according to the actual position and size difference of the battery cells, the relative movement of the two first X-direction first-level sliding members 231 and the second X-direction first-level sliding members 232 can be used to accurately adapt to the positioning requirements, achieve millimeter-level high-precision positioning, and effectively improve the accuracy and stability of battery cell clamping.

[0039] like Figure 4 、 Figure 5 It can also be clearly seen from the figure that the X-direction pushing part 2 is further provided with an X-direction guide assembly 26. The X-direction guide assembly 26 includes an X-direction slide rail 261, a first X-direction slider 262, and a second X-direction slider 263. The first X-direction slider 262 and the second X-direction slider 263 are respectively and detachably fixed on the bottom walls of the first X-direction primary sliding member 231 and the second X-direction primary sliding member 232 in a one-to-one correspondence. In actual application, with the help of the guiding force of the X-direction guide assembly 26, the first X-direction primary sliding member 231 and the second X-direction primary sliding member 232 are able to achieve directional translational motion, ensuring that the lateral thrust of the X-direction pushing linear motion element 22 is accurately transmitted to the battery cell, thereby completing the X-direction position adjustment.

[0040] like Figure 7 As shown in the figure, the X-direction secondary elastic buffer module 25 includes an X-direction mounting base plate 251, an X-direction side thrust plate 252, and an X-direction secondary elastic coupling assembly 253. The X-direction mounting base plate 251 is mounted on the load-bearing beam 24. The X-direction side thrust plate 252 is used to directly push up the battery cell. The number of the X-direction secondary elastic coupling assemblies 253 is two, and they are arranged in parallel and assembled between the X-direction mounting base plate 251 and the X-direction side thrust plate 252. When the X-direction side thrust plate 252 pushes the battery cell laterally, the X-direction secondary elastic coupling assembly 253 is compressed and stores elastic potential energy synchronously.

[0041] Likewise Figure 7 As shown in FIG, the X-direction secondary elastic coupling assembly 253 is composed of an X-direction secondary guide 2531 and an X-direction secondary elastic member 2532. The X-direction secondary guide 2531 is inserted into the X-direction mounting base plate 251 and extends through the X-direction side thrust plate 252 in the X-direction direction. The X-direction secondary elastic member 2532 is sleeved onto the X-direction secondary guide 2531 and is elastically compressed between the X-direction mounting base plate 251 and the X-direction side thrust plate 252.

[0042] In actual application, when the load beam 24 is pushed forward by the X-direction push linear motion element 22, the X-direction mounting base plate 251, acting as the base structure, displaces synchronously, thereby driving the X-direction side push plate 252 to approach the battery cell. When the X-direction side push plate 252 contacts the battery cell and generates a pushing force, the X-direction secondary elastic member 2532 begins to compress and store energy. Simultaneously, the X-direction secondary guide member 2531 (such as a precision guide post) slides within the guide hole of the X-direction side push plate 252, allowing the X-direction side push plate 252 to move linearly along the X-direction. As the battery cell gradually approaches the positioning position, the compression of the X-direction secondary elastic member 2532 increases, and its stored elastic potential energy is converted into positioning force. After the battery cell contacts the limit member 12, the X-direction secondary elastic member 2532 continues to provide cushioning, effectively avoiding the occurrence of rigid impact and achieving high-precision, flexible positioning of the battery cell.

[0043] like Figure 8 、 Figure 9 As shown in FIG, the Y-direction pushing portion 3 is composed of two Y-direction pushing mechanisms 31 arranged side by side. The Y-direction pushing mechanism 31 includes a Y-direction pushing linear motion element 311, a Y-direction elastic buffer module 312, and a Y-direction side thrust member 313. The Y-direction elastic buffer module 312 is driven by the Y-direction pushing linear motion element 311 and is used to support the Y-direction side thrust member 313.

[0044] In practice, the two Y-direction pushing linear motion elements 311 are activated synchronously, each driving the Y-direction side thrusters 313 toward the battery cell along the Y-axis. When the Y-direction side thrusters 313 contact the side of the battery cell, the Y-direction elastic buffer module 312 begins to compress and store energy, protecting the battery cell from rigid impact forces. As the Y-direction pushing linear motion elements 311 continue to advance, the Y-direction elastic buffer module 312 compresses more, and the stored elastic potential energy is converted into a stable positioning force, pushing the battery cell until it fully aligns with the Y-direction limiting surface of the limiting member 12, achieving high-precision positioning of the battery cell. Furthermore, if there is any Y-direction dimensional deviation between the two battery cells, the Y-direction elastic buffer module 312 automatically compensates by varying the amount of compression.

[0045] Furthermore, compared with the aforementioned X-direction primary elastic buffer module 23 , the Y-direction elastic buffer module 312 has the same design concept, and the functions and implementation effects are comparable, and therefore will not be described in detail here for the sake of space.

[0046] Finally, it should be noted that in order to achieve stable positioning of the battery cell, Figure 3As shown in the figure, the positioning jig 1 is also equipped with a vacuum suction nozzle 13. Under the coordinated action of the X-direction pushing part 2 and the Y-direction pushing part 3, after the battery cell is positioned relative to the limit member 12, the vacuum suction nozzle 13 immediately activates the vacuum adsorption system, generating an adsorption force through internal negative pressure, firmly attaching the battery cell to the supporting surface of the positioning jig 1. In this way, the adverse effects of vibration, inertia, or external interference on the precise positioning of the battery cell in subsequent processes are effectively eliminated.

[0047] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
