Description

Technical Field

[0001] The utility model relates to the field of battery production, and in particular to a sleeve connection mechanism for a battery core steel strip. Background Art

[0002] The traditional battery core steel strip splicing process has long relied too much on cumbersome manual operations. This traditional operation method is not only inefficient and difficult to adapt to the fast-paced needs of modern production lines, but also accompanied by many inconveniences in the actual operation process. From a safety perspective, manual operation may pose a safety hazard and easily lead to work-related accidents; from a quality perspective, human factors may lead to low splicing accuracy and affect the overall performance of the battery core. Therefore, we urgently need to deeply improve and optimize this process through technological innovation and automation to achieve more efficient, more accurate and safer steel strip splicing, thereby improving production efficiency, reducing production costs, and injecting new impetus into the sustainable development of the enterprise. Utility Model Content

[0003] In view of this, the utility model provides a socketing mechanism for a battery cell steel strip, wherein a first guide end plate and a second guide end plate are arranged on a second-stage steel strip socketing frame, and the sizes and positions of the two guide end plates precisely correspond to the sizes and positions of the hollows at both ends of the battery cell, thereby ensuring that the steel strip can be accurately socketed on the hollows of the battery cell during the socketing process, thereby not only improving the socketing accuracy, but also avoiding the degradation of battery cell performance or safety hazards caused by improper socketing position, thereby effectively ensuring that the steel strip is stably socketed on the battery cell.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A socketing mechanism for a battery cell steel strip comprises a machine platform, a holding assembly arranged on the machine platform and used for holding up the battery cell, and a socketing assembly used for socketing the steel strip on the battery cell, the socketing assembly comprising a socketing power unit installed on the machine platform, a first-stage steel strip socketing frame driven by the socketing power unit, and a second-stage steel strip socketing frame slidably connected to the first-stage steel strip socketing frame, the steel strip is placed on the first-stage steel strip socketing frame, the second-stage steel strip socketing frame can be movably placed on the holding assembly, the second-stage steel strip socketing frame is provided with a first guide end plate and a second guide end plate, the steel strip is socketed on the outer sides of the first guide end plate and the second guide end plate, the size and position of the first guide end plate and the second guide end plate correspond to the size and position of the hollowing out at both ends of the battery cell.

[0006] The second-stage steel strip socket frame is provided with a first guide end plate and a second guide end plate. The size and position of these two guide end plates precisely correspond to the size and position of the hollows at both ends of the battery cell, which can ensure that the steel strip can be accurately socketed on the hollows of the battery cell during the socketing process. This not only improves the socketing accuracy, but also avoids the degradation of battery cell performance or safety hazards caused by improper socketing position, and effectively ensures that the steel strip is stably socketed on the battery cell.

[0007] During operation, the steel belt is placed on the first-order steel belt sleeve frame, and the sleeve power unit pushes the first-order steel belt sleeve frame upward, and at the same time drives the steel belt and the second-order steel belt sleeve frame to move upward synchronously. The second-order steel belt sleeve frame moves upward and drives the first guide end plate and the second guide end plate to move upward synchronously. The first guide end plate and the second guide end plate move upward and enter the hollows at both ends of the battery cell. When the first guide end plate and the second guide end plate completely fill the hollows at both ends of the battery cell, they will stop moving upward due to the force of the battery cell. At this time, the second-order steel belt sleeve frame stops moving upward, and the first-order steel belt sleeve frame slides relative to the second-order steel belt sleeve frame. The first-order steel belt sleeve frame keeps moving upward under the push of the sleeve power unit, driving the steel belt upward, thereby putting the steel belt on the battery cell.

[0008] Preferably, the first-stage steel belt sleeve frame and the second-stage steel belt sleeve frame are slidably connected via a linear guide rail and a hydraulic buffer.

[0009] The first-stage steel belt socket frame and the second-stage steel belt socket frame are connected by sliding through linear guides and hydraulic buffers, which not only ensures the stability of the socket process, but also greatly improves the accuracy of the socket. The linear guide provides a stable sliding path for the socket frame, so that the socket frame can maintain accurate alignment when moving up and down, avoiding socket deviation caused by shaking. The addition of hydraulic buffers plays a buffering role when the socket frame moves into place, reducing the impact on the socket frame and extending its service life.

[0010] Preferably, the second-step steel belt socket frame includes a first second-step plate, a second second-step plate, a third second-step plate and a fourth second-step plate which are sequentially connected end to end to form a rectangular frame, the first guide end plate is installed on the second second-step plate, and the second guide end plate is installed on the fourth second-step plate.

[0011] The two-stage steel belt socket frame adopts a rectangular frame design, including the first second-stage plate, the second second-stage plate, the third second-stage plate and the fourth second-stage plate. This design can effectively lift the steel belt and make the socket frame structure stable and able to withstand a large socket force. At the same time, the first guide end plate and the second guide end plate are respectively installed on the second second-stage plate and the third second-stage plate, which precisely correspond to the hollow parts at both ends of the battery cell, ensuring that the steel belt can be accurately inserted.

[0012] Preferably, the first-step steel belt socket frame includes a first first-step plate connected to the first second-step plate, a second first-step plate connected to the first first-step plate, a third first-step plate connected to the second first-step plate and connected to the third second-step plate, and a fourth first-step plate connected to the third first-step plate, the bottom of the first first-step plate is connected to a first supporting bar for supporting the steel belt, the bottom of the second first-step plate is connected to a second supporting bar for supporting the steel belt, the bottom of the third first-step plate is connected to a third supporting bar for supporting the steel belt, and the bottom of the fourth first-step plate is connected to a fourth supporting bar for supporting the steel belt.

[0013] The design of the first-stage steel belt socket frame also fully considers support and stability. It includes four first-stage plates connected to the second-stage steel belt socket frame, and a support bar is set at the bottom of each first-stage plate to support the steel belt. This design not only ensures the stability of the steel belt during the socketing process, but also allows the steel belt to be evenly stressed, avoiding deformation or damage caused by uneven stress.

[0014] Preferably, the first first-step plate is connected to the first second-step plate via a linear guide rail and a hydraulic buffer, and the third first-step plate is connected to the third second-step plate via a linear guide rail and a hydraulic buffer.

[0015] Linear guides and hydraulic buffers are used to connect the first and second step plates, as well as the third and third step plates, which not only ensures the stability and accuracy of the sleeve frame during the sliding process, but also greatly enhances the stability and durability of the structure. The linear guide provides a precise and reliable sliding path, allowing the sleeve frame to maintain a stable posture when moving up and down, effectively avoiding sleeve failure caused by offset or shaking. The addition of hydraulic buffers effectively reduces the impact and vibration when the sleeve frame is in place, extending the service life of the equipment, while also reducing noise generation and improving the quality of the working environment.

[0016] Preferably, the second first-step plate is connected to the first push sleeve, the fourth first-step plate is connected to the second push sleeve, there are two sleeve-connected power units, and the output ends of the two sleeve-connected power units are respectively connected to the first push sleeve and the second push sleeve.

[0017] The first push sleeve and the second push sleeve are connected to the second first-stage plate and the fourth first-stage plate respectively, and there are two sleeve power units, which are connected to the two push sleeves respectively. This design allows the sleeve power to act more evenly on the sleeve frame, improving the efficiency and stability of the sleeve. The two sleeve power units work together to push the sleeve frame upward more quickly, and can also more accurately control the position and speed of the sleeve frame, ensuring that the steel belt can be accurately and quickly sleeved on the battery cell.

[0018] Preferably, the first second-step plate is provided with a first support block and a second support block, and the second first-step plate can be movably placed on the first support block and the second support block; the third second-step plate is provided with a third support block and a fourth support block, and the third first-step plate can be movably placed on the third support block and the fourth support block.

[0019] Support blocks are set on the first and third second-stage plates to support and stabilize the second-stage steel belt socket frame, which not only enhances the structural strength of the socket frame, but also makes the socket process more stable and reliable. The setting of the support blocks effectively prevents the socket frame from shaking and deforming during movement, ensuring the accuracy and success rate of socketing.

[0020] Preferably, the lifting assembly includes a base connected to the machine, an adjustment rail connected to the base, and a supporting block arranged on the adjustment rail, and the first-stage steel belt sleeve frame and the second-stage steel belt sleeve frame are arranged on the periphery of the supporting block.

[0021] The lifting assembly adopts a combination design of a bottom bracket, an adjustment rail and a support block, which is not only stable and reliable, but also highly adjustable. The bottom bracket is connected to the machine table, providing a stable support foundation for the entire lifting assembly. The setting of the adjustment rail allows the support block to be fine-tuned in the horizontal direction to adapt to battery cells of different sizes and shapes. This flexibility enables the socketing mechanism to be applicable to a wider range of application scenarios, improving its versatility and adaptability.

[0022] Preferably, a bottom bracket support block is provided on the side wall of the supporting block, and the second-stage steel belt sleeve frame can be movably placed on the bottom bracket support block.

[0023] The side wall of the supporting block is provided with a bottom support block, and the second-order steel belt socket frame can be movably placed on the bottom support block, which not only provides stable support for the second-order steel belt socket frame, but also makes the socket process more stable and smooth. The bottom support block can effectively withstand the force generated during the socket process, prevent the second-order steel belt socket frame from shaking or shifting, thereby ensuring the accuracy and stability of the socket. The coordinated work of the lifting component and the socket component is also a highlight. The first-order steel belt socket frame and the second-order steel belt socket frame are arranged on the periphery of the supporting block. This layout makes the socket process more compact and efficient. During the socket process, the lifting component can stably support the battery cell and provide an accurate socket position for the socket component. At the same time, the socket component can accurately control the socket position and strength of the steel belt to ensure that the steel belt can be tightly and smoothly socketed on the battery cell.

[0044] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0045] The present embodiment provides a sleeve connection mechanism for a battery core steel strip, including a machine 100, a lifting assembly 200 disposed on the machine 100 and used to lift a battery core 001, and a sleeve connection assembly 300 for sleeve connection of a steel strip 002 to the battery core, wherein the sleeve connection assembly 300 includes a sleeve connection power unit 310 installed on the machine 100, a first-stage steel strip sleeve connection frame 320 driven by the sleeve connection power unit 310, and a second-stage steel strip sleeve connection frame 320 slidably connected to the first-stage steel strip sleeve connection frame 320.
