Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery manufacturing technology, specifically relating to a pre-connection device for battery cells before they are inserted into the casing. Background Technology
[0002] Batteries are classified into pouch cells, cylindrical cells, and prismatic cells based on their outer casing. Except for pouch cells, which are formed by wrapping the cells in an aluminum-plastic film and then sealing the edges, the other two types are manufactured by pushing the bare cells into a pre-formed open aluminum casing and then sealing it. Due to fluctuations in the parameters of the incoming electrode materials, the produced bare cells may not be completely consistent in specifications.
[0003] In most cases, during the installation of bare battery cells, the aluminum casing is horizontally fixed on one side, and the bare cell is pushed into the casing via a push rod and a horizontal slide. Due to the actual specifications of the bare cells mentioned earlier, inconsistencies in the horizontal height of the bare cells during installation can cause them to collide with the casing, resulting in their scrapping. This phenomenon is particularly serious when switching battery models. Currently, when changing battery models, the equipment precision is usually adjusted by repeatedly installing bare cells, which results in significant waste, a long adjustment cycle, and reduced production capacity. Summary of the Invention
[0004] The purpose of this invention is to provide a pre-connection device for battery cells before they are installed in the casing, so as to solve the problems existing in the background art.
[0005] The purpose of this utility model is achieved as follows: a pre-connection device for battery cells before they are inserted into the casing, comprising a bracket and a pre-connection mechanism. A middle layer frame is provided on the upper side of the bracket, and a first push rod is fixedly provided on the outer side of the middle layer frame. A top platform is provided on the top of the bracket, and a second push rod is fixedly provided on the upper side of the top platform. A push head is provided at the end of the second push rod. The pre-connection mechanism includes an embedding end and a receiving end. The embedding end is engaged with the first push rod. A bare battery cell is placed inside the embedding end. A receiving end is provided on the right side of the embedding end, and a casing is provided inside the receiving end.
[0006] A connector is provided on the right side of the embedded end.
[0007] An expansion port is provided on the left side of the receiving end.
[0008] Both the connector and the expansion port are V-shaped.
[0009] An extension rod is provided on the outside of the first push rod.
[0010] A push plate is provided at the end of the extension rod.
[0011] The embedded end consists of symmetrically arranged semi-clamps.
[0012] The beneficial effects of this utility model are as follows: This device, through pre-interlocking of the equipment before the bare battery cell is inserted into the casing, fine-tunes the direction of the bare battery cell insertion into the casing, achieving rapid and accurate docking between the bare battery cell and the casing, significantly improving the automation level and production efficiency of the production line; the snap-fit design of the insert end and the receiving end, as well as the "V"-shaped matching method of the plug and the expansion port, ensure that the bare battery cell can enter the casing stably and accurately during the pushing process. Through pre-interlocking, it avoids collision damage caused by abnormal alignment between the bare battery cell and the casing; it is not limited to the horizontal insertion method, and any insertion method can be used, regardless of the size and specifications of the bare battery cell or the pushing method. The pre-interlocking method is not limited to the "V"-shaped interface; by adjusting the parameters of components such as the bracket, insert end, and receiving end, it can adapt to the docking requirements of bare battery cells of different specifications and models with the casing, improving the versatility and adaptability of the equipment.

[0018] The present invention will be further described below with reference to the accompanying drawings. Example
[0019] like Figure 1-4As shown, a pre-connection device for battery cells before they are installed in a casing includes a support 1 and a pre-connection mechanism. A middle layer frame 2 is provided on the upper side of the support 1, and a first push rod 3 is fixedly provided on the outer side of the middle layer frame 2. A top platform 4 is provided on the top of the support 1, and a second push rod 5 is fixedly provided on the upper side of the top platform 4. A push head 6 is provided at the end of the second push rod 5. The pre-connection mechanism includes an embedding end 7 and a receiving end 9. The embedding end 7 is engaged with the first push rod 3. A bare battery cell 8 is placed inside the embedding end 7. The receiving end 9 is provided on the right side of the embedding end 7, and a casing 10 is provided inside the receiving end 9.
[0020] In use, the bare battery cell 8 is placed inside the insert end 7, ensuring that the housing 10 to be docked is already placed inside the receiver end 9, and that the expansion port 12 on the left side of the receiver end is open. The device is activated, and the first push rod 3 begins operation. As the first push rod 3 continues to push, the insert end 7 and the receiver end 9 completely align, completing the docking guidance. Subsequently, the second push rod 5 pushes the bare battery cell 8. Because it has already been guided and positioned by the pre-docking mechanism, the bare battery cell 8 will not collide with the port of the housing 10 during the second push rod 5's pushing process, ultimately completing the guided insertion into the housing. This device exhibits significant advantages in improving production efficiency, ensuring docking accuracy, reducing operational difficulty, protecting the bare battery cell and housing, and enhancing adaptability. Example
[0021] like Figure 1-4 As shown, a pre-connection device for battery cells before they are installed in a casing includes a support 1 and a pre-connection mechanism. A middle layer frame 2 is provided on the upper side of the support 1, and a first push rod 3 is fixedly provided on the outer side of the middle layer frame 2. A top platform 4 is provided on the top of the support 1, and a second push rod 5 is fixedly provided on the upper side of the top platform 4. A push head 6 is provided at the end of the second push rod 5. The pre-connection mechanism includes an embedding end 7 and a receiving end 9. The embedding end 7 is engaged with the first push rod 3. A bare battery cell 8 is placed inside the embedding end 7. The receiving end 9 is provided on the right side of the embedding end 7, and a casing 10 is provided inside the receiving end 9.
[0022] For better performance, a connector 11 is provided on the right side of the embedded end 7. The embedded end 7 can be easily connected to the receiving end 9 via the connector 11.
[0023] For better performance, an expansion port 12 is provided on the left side of the receiving end 9. The expansion port 12 cooperates with the connector 11 of the embedded end 7.
[0024] For better results, both the connector 11 and the expansion port 12 are V-shaped. The V-shape is the most convenient for the connector 11 and the expansion port 12 to mate, but other reasonable shapes can also be used.
[0025] For better results, an extension rod 13 is provided on the outside of the first push rod 3.
[0026] For better results, a push plate 14 is provided at the end of the extension rod 13.
[0027] For better results, the embedding end 7 is composed of symmetrically arranged semi-clamping platforms 15. This design results in more uniform force distribution when clamping the bare battery cell 8, reduces the mechanical stress on the bare battery cell 8 during the pushing process, and facilitates the adjustment of the embedding end 7.
[0028] In use, the bare battery cell 8 is placed inside the embedded end 7, which consists of symmetrically arranged semi-clamps 15 that stably hold the bare battery cell 8, preventing it from shaking. This ensures that the housing 10 to be docked is placed inside the receiving end 9, and that the expansion port 12 on the left side of the receiving end is open. The device is activated, and the first push rod 3 begins to operate, pushing the embedded end 7 towards the receiving end 9 via its extension rod 13 and push plate 14. When the connector 11 on the right side of the embedded end 7 approaches the expansion port 12 on the left side of the receiving end 9, the "V" shape of the connector 11 matches the "V" shape of the expansion port 12, and the connector 11 gradually enters the expansion port 12. As the first push rod 3 continues to push, the embedded end 7 and the receiving end 9 are completely aligned, completing the docking guidance. Subsequently, the second push rod 5 pushes the bare battery cell 8. Since it has already been guided and positioned by the pre-docking mechanism, the bare battery cell 8 will not collide with the port of the housing 10 during the second push rod 5's pushing process, ultimately completing the guided insertion into the housing. This device demonstrates significant advantages in improving production efficiency, ensuring docking accuracy, reducing operational difficulty, protecting bare cells and casings, and enhancing adaptability.
