Description

Technical Field

[0001] This application belongs to the field of battery production technology, and more specifically, relates to a module extrusion and shaping device and a battery production system. Background Technology

[0002] During battery production, the battery modules need to be extruded and shaped along their length to optimize the terminal spacing. After each shaping process, the battery modules need to be secured with straps. However, battery modules are designed with different extruded lengths depending on the model. In existing extrusion equipment, when the length of the battery module changes, the center position of the module after extrusion changes, and the pre-fitted straps need to be readjusted to accommodate the new length, which is quite cumbersome. Utility Model Content

[0003] This application provides a module extrusion and shaping device that eliminates the need to adjust the pre-assembled strap structure, making it more convenient.

[0004] The technical solution adopted in this application embodiment is: to provide a module extrusion and shaping device, including:

[0005] substrate;

[0006] A support platform protrudes from the substrate. The support platform has a central reference and multiple slit groups. Each slit group includes two slits for inserting straps. The two slits are located at both ends of the support platform along a first direction and are symmetrical about the central reference. The slits extend through the support platform along a second direction and are open at the top. At one end of the support platform, the slits of each slit group are arranged sequentially from the inside to the outside. The spacing between the two slits of each slit group matches the design length of a battery module of a certain type. The dimension of the support platform in the second direction is larger than the dimension of the battery module to be extruded in the second direction. The second direction is perpendicular to the first direction.

[0007] The extrusion mechanism includes two extrusion structures and a drive assembly. The two extrusion structures are movably disposed on the substrate along a first direction and are arranged opposite to each other. The drive assembly is used to drive the two extrusion structures to move symmetrically towards each other about the central reference, so as to extrude the battery module between the two extrusion structures to the designed length.

[0008] Furthermore, the dimensions of the support platform in the first direction match the design length of a battery module.

[0009] Furthermore, it also includes multiple strap limiting blocks, which are detachably disposed on the side of the support platform perpendicular to the second direction. One strap limiting block is disposed on the side of the slit near the central reference, or on the end of the support platform along the first direction.

[0010] Furthermore, it also includes a limiting member disposed at one end of the support platform, the limiting member having a limiting groove that extends through along the second direction and opens upward, and the strap can be embedded into the limiting groove.

[0011] Furthermore, the module extrusion and shaping device also includes an insulating pad layer, which covers the support platform and matches the shape of the support platform. The insulating pad layer is provided with a cut end that communicates with the slit.

[0012] Furthermore, the driving assembly includes a driver corresponding to each of the extrusion structures. The two drivers are disposed at both ends of the substrate along the first direction and are symmetrical about the central reference. The drivers are connected to the corresponding extrusion structures to drive the extrusion structures to move along the first direction.

[0013] Furthermore, the driving assembly also includes connectors corresponding to the extrusion structures. The driver is located at the bottom of the substrate. The substrate has a through opening. The distance between one end of the opening and the center reference is less than the distance between the slit and the center reference. One end of the connector is connected to the extrusion structure, and the other end passes through the opening and is connected to the driver. The end of the support platform has a clearance notch extending in the first direction corresponding to the connector.

[0014] Furthermore, it also includes a foolproof component, wherein the foolproof block is disposed at one end of the clearance notch, the strap includes a strap body and a connector that connects and fixes the ends of the strap body, the foolproof block is provided with a slot, the width of the slot is greater than the thickness of the strap body and less than the thickness of the connector.

[0015] Furthermore, the extrusion structure includes:

[0016] A slide table is disposed on the substrate along the first direction, and a mounting surface is provided at one end of the slide table near the central reference.

[0017] A clamping block is disposed on the mounting surface, and one end of the clamping block near the central reference has a pressing end face perpendicular to the first direction.

[0018] This application also provides a battery production system, including the module extrusion and shaping device described above.

[0019] The beneficial effects of the module extrusion and shaping device provided in this application embodiment are as follows: In the module extrusion and shaping device of this application embodiment, each model of battery module has a corresponding slit group. Before pressing, a binding strap of the corresponding length can be pre-embedded into the slit of the corresponding slit group. During operation, firstly, according to the model of the battery module to be processed, a binding strap of the corresponding length is selected and directly embedded into the slit of the matching slit group on the support platform. Here, no adjustment of the length or position of the binding strap is required, making the operation very convenient. The battery module to be extruded is placed on the support platform, and the extrusion mechanism is started. Its drive component drives the two extrusion structures to move symmetrically towards each other along a first direction about a central reference, thereby extruding the battery module to optimize the spacing between the cell terminals inside the module. Extrusion continues until the spacing between the two extrusion structures matches the design length of the battery module, at which point extrusion stops, and the extrusion structures are then removed. Because of the symmetrical extrusion from both sides, the spacing between the cell terminals is more uniform after extrusion. The two ends of the battery module are also symmetrical about the central reference along the first direction after extrusion, meaning the two ends of the battery module are precisely located within the two slits of the corresponding slit group (i.e., within the binding strap). Finally, the binding strap embedded in the slits is lifted, tightening the battery module and securing it. When replacing different models of battery modules, simply locate the corresponding slit group according to the module model and insert the binding strap of the appropriate length. No adjustments to the support platform or the slit group structure are required, making it more convenient, greatly saving time, improving production efficiency, and applicable to different models of battery modules.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] Please see Figure 1 and Figure 2 The module extrusion and shaping device provided in the embodiments of this application will now be described.

[0040] Reference Figure 1 and Figure 2 The present application provides a module extrusion and shaping device, which includes a substrate 10, a support platform 20 and an extrusion mechanism 30.

[0041] The substrate 10 is the foundation of the entire module extrusion and shaping device, providing a stable and reliable mounting surface for other components, namely the support platform 20 and the extrusion mechanism 30, ensuring that the entire device can always maintain a stable state during operation.

[0042] Reference Figure 3 and Figure 4 A support platform 20 protrudes from the substrate 10. The support platform 20 has a central reference 21 and multiple slot groups 22. Each slot group 22 includes two slots 221 into which a strap 80 can be inserted. The two slots 221 are located at both ends of the support platform 20 along the first direction X and are symmetrical about the central reference 21. The slots 221 extend through the second direction Y and have an opening 11 at the top. At one end of the support platform 20, the slots 221 of each slot group 22 are arranged sequentially from the inside to the outside. The spacing between the two slots 221 of each slot group 22 matches the design length of a battery module of a certain model. The dimension of the support platform 20 in the second direction Y is larger than the dimension of the battery module to be extruded in the second direction Y. The second direction Y is perpendicular to the first direction X.

[0043] The spacing between the two slits 221 mentioned here matches the design length of a certain type of battery module. This means that after the battery module is squeezed to the design length, the two end plates at both ends of the battery module (i.e., the two end faces perpendicular to the first direction) are exactly located between the two slits. There are pre-fitting straps between these two slits, so the two ends of the battery are also located between the two ends of the straps. By lifting the straps, the battery module can be bound and the length fixed.

[0044] First, the support platform 20 is provided with a central reference 21, which is a reference point that acts like an "axis of symmetry" and provides a clear symmetrical basis for subsequent extrusion operations.

[0045] Secondly, the support platform 20 is provided with multiple slot groups 22, each slot group 22 containing two slots 221, which are located at both ends of the support platform 20 along the first direction X and are symmetrically distributed about the central reference 21. Here, the first direction X can be the length direction of the battery module, and also the front-to-back direction. The slots 221 extend through along the second direction Y, which is perpendicular to the first direction X, and have an opening 11 at the top. This design facilitates the insertion of the binding strap 80. The second direction Y can be the width direction. Specifically, the binding strap 80 is a steel strip, with its ends connected in a rectangular shape to match the shape of the extruded battery module.

[0046] Reference Figure 3 and Figure 4 At one end of the support platform 20, the slits 221 of each slit group 22 are arranged sequentially from the inside out, and the spacing between the two slits 221 of each slit group 22 is precisely matched with the design length of a specific type of battery module. This means that different types of battery modules can find corresponding slit groups 22 on the support platform 20, and the outermost slits 221 correspond to battery modules with larger extruded design lengths.

[0047] The dimension of the support platform 20 in the second direction Y is larger than the dimension of the battery module to be extruded in that direction. The second direction Y can be the width direction of the battery module, and also the left-right direction. When the strap 80 is embedded in the seam and fitted onto the support platform 20, the width of the extruded battery module will not exceed the support platform 20, that is, it will not exceed the range of the strap 80, so the strap 80 can cover the battery module.

[0048] Reference Figure 4 Specifically, the support platform 20 has multiple slot groups 22, and each slot group 22 contains two slots 221. These slots 221 divide the support platform 20 into multiple parts. Taking two slot groups 22 as an example, the support platform 20 is divided into a main plate 24, two first sub-plates 25, and two second sub-plates 26, all of which can be rectangular. Looking along the first direction X, the various parts of the support platform 20 are as follows: second sub-plate 26 - slot 221 - first sub-plate 25 - slot 221 - main plate 24 - slot 221 - first sub-plate 25 - slot 221 - second sub-plate 26, with the central reference 21 located at the center of the main plate.

[0049] Reference Figure 3 and Figure 4The strap 80 itself is rectangular, fitting the rectangular sections of the support platform 20 and the overall regular structure. When the strap 80 is embedded in the slot 221, two main wrapping scenarios occur. One is that the strap 80 wraps around the outside of the main body 24, embedded in the slot 221 between the first sub-plate 25 and the main body 24. In this case, the main body 24 is within the rectangular space enclosed by the strap 80. The strap 80 surrounds the main body 24 from all sides through the slot 221, like a rectangular "hoop" around the main body 24, thus constraining and fixing the corresponding area of ​​the battery module placed above the main body 24. The other scenario is that the strap 80 is embedded in the slot 221 between the second sub-plate 26 and the first sub-plate 25, wrapping around "first sub-plate 25 - slot 221 - main body 24 - slot 221 - first sub-plate 25". In other words, depending on the different design dimensions of the battery module after extrusion, the strap 80 will be embedded in the corresponding slit 221 to position the loop of the strap 80. After the battery module is extruded, the two ends are located between the corresponding slits 221, and the strap 80 can be lifted from the slits 221 to tighten the battery module.

[0050] Reference Figure 1 and Figure 2 The extrusion mechanism 30 includes two extrusion structures 31 and a drive assembly 32. The two extrusion structures 31 are movably disposed on the substrate 10 along the first direction X and are arranged opposite to each other. The drive assembly 32 is used to drive the two extrusion structures 31 to move symmetrically towards each other about the central reference 21, so as to extrude the battery module between the two extrusion structures 31 to the designed length.

[0051] These two extrusion structures 31 are components that directly contact the battery module and apply extrusion force. The spacing between them is adjusted by moving in the first direction X to accommodate battery modules of various sizes and specifications.

[0052] The driving component 32 is responsible for driving the two extrusion structures 31 to move symmetrically towards each other around the central reference 21. Under the action of the driving component 32, the two extrusion structures 31 will move towards the center simultaneously with the central reference 21 as a reference, and the speed, distance and other parameters of movement can be kept consistent, thereby ensuring that the extrusion force on both sides of the module is always uniform and symmetrical when extruding the battery module. This symmetrical extrusion method can effectively avoid many problems caused by uneven force, such as abnormal deformation of the battery module after extrusion, such as excessive extrusion at one end and insufficient extrusion at the other end, causing the module shape to become distorted and irregular; or damage to internal components such as battery cells and connectors 322 due to excessive local force, such as deformation of battery plates and loosening of solder joints.

[0053] The symmetrical extrusion on both sides also makes the two ends of the extruded battery module symmetrical about the central reference 21. At this time, the two ends of the battery module are exactly located between the two slits 221 of the corresponding slit group 22. The binding straps 80 are pre-embedded in the two slits 221. After lifting the binding straps 80, the binding straps 80 can be put on the battery module to fix the battery module.

[0054] The following describes the working process of the module extrusion and shaping device according to an embodiment of this application:

[0055] First, select a strap 80 of the corresponding length according to the model of the battery module to be processed, and embed the strap 80 into the slit 221 of the corresponding slit group 22 of the support platform 20. Next, place the battery module to be extruded on the support platform 20, start the extrusion mechanism 30, and drive the two extrusion structures 31 to move symmetrically towards each other along the first direction X and around the central reference 21 to extrude the battery module until the distance between the two extrusion structures 31 matches the designed length of the battery module. Then, remove the extrusion structure 31. Finally, lift the strap 80 embedded in the slit 221, and the strap 80 will tighten the battery module, completing the fixation. If a different model of battery module is used, simply find the corresponding slit group 22 according to the model and embed the strap 80 of the corresponding length. No additional structural adjustments are required, the operation is simple, and it can adapt to different models of battery modules.

[0056] Reference Figure 3 and Figure 4 The dimension of the support platform 20 in the first direction X matches the designed length of a battery module. A strap 80 of corresponding length to this battery module can be fitted onto the entire support platform 20. After extruding the battery cells, the strap 80 is lifted to secure the battery module. This effectively adds a slotted assembly 22 to the device. This slotted assembly 22 is located on the periphery of the support platform 20 and is used when the battery module extrusion and shaping device is compatible with a particular battery module model.

[0057] Reference Figure 3 and Figure 4 It also includes a plurality of strap limiting blocks 40, which are detachably disposed on the side of the support platform 20 perpendicular to the second direction Y. One strap limiting block 40 is disposed on the side of the slit 221 near the central reference 21, or on the end of the support platform 20 along the first direction X.

[0058] Multiple strap limit blocks 40 are detachably installed on the side of the support platform 20 perpendicular to the second direction Y (e.g., the left and right sides).

[0059] Specifically, there are two possible positions for the strap limiting block 40. In the first case, the strap limiting block 40 is positioned on the side of the slit 221 closest to the center reference 21. When the strap 80 is inserted into the slit 221, the strap limiting block 40 can be fitted inside, tightening the strap 80 and ensuring its stability, preventing unnecessary movement of the strap 80 in the second direction Y during subsequent device operation. In the second case, the strap limiting block 40 is located at the end (e.g., the front and rear ends) of the support platform 20 along the first direction X. When the strap limiting block 40 is positioned at both ends of the support platform 20 (i.e., the largest design size of the battery cell module), the strap limiting block 40 can be fitted inside, tightening the strap 80 and ensuring its stability, preventing unnecessary movement of the strap 80 in the second direction Y during subsequent device operation.

[0060] Reference Figure 3 and Figure 4 The system also includes a limiting member 50 located at one end of the support platform 20. The limiting member 50 has a limiting groove 51 extending along the second direction Y with its opening 11 facing upwards. The strap 80 can be embedded in the limiting groove 51. The limiting groove 51 extends along the second direction Y, which is perpendicular to the length direction of the battery module (the first direction X). The strap 80 can be embedded in the limiting groove 51, and the limiting member 50 serves to limit the strap 80 in the first direction X. In actual operation, after the strap 80 is embedded in the slot 221 of the support platform 20, although it is somewhat fixed, it is prone to sliding and shifting in the first direction X due to external forces such as squeezing operations and equipment vibration, affecting the fixing effect on the module and the accuracy of operation. With the limiting groove 51 of the limiting member 50, its two side walls act like "tracks," restricting the movement of the strap 80 in the first direction X, ensuring it remains in a fixed position within a limited space, and allowing the strap 80 to securely surround the module and the support platform 20.

[0061] Reference Figure 3 and Figure 4 The module extrusion and shaping device further includes an insulating pad 60, which covers the support platform 20 and matches the shape of the support platform 20. The insulating pad 60 is provided with a cutout 61 that corresponds to and communicates with the slit 221.

[0062] During the extrusion and shaping of the battery module and its subsequent use, it is necessary to avoid any potential electrical conductivity between the battery module and the support platform 20 to prevent electrical faults such as short circuits caused by accidental conductivity. Therefore, an insulating pad 60 is provided. The insulating pad 60 is insulating and separates the battery module from the support plate, thereby ensuring the safety and stability of the entire device and the battery module.

[0063] Meanwhile, the insulating pad 60 is provided with cutouts 61 that correspond to and communicate with the slits 221 of the support platform 20. When the strap 80 is to be inserted into the slits 221 of the support platform 20, since the insulating pad 60 covers it, the strap 80 cannot be inserted into the slits 221 without the cutouts 61. With these corresponding cutouts 61, the strap 80 can be accurately inserted into the slits 221, which not only realizes the normal fixing function of the strap 80 to the battery module, but also ensures that the insulating function of the insulating pad 60 is not affected, so that the structure and function of the entire device can work together more perfectly.

[0064] Reference Figure 1 and Figure 2 The driving component 32 includes a driver 321 that corresponds one-to-one with the extrusion structure 31. The two drivers 321 are disposed at both ends of the substrate 10 along the first direction X and are symmetrical about the central reference 21. The driver 321 is connected to the corresponding extrusion structure 31 to drive the extrusion structure 31 to move along the first direction X.

[0065] Two actuators 321 are mounted at both ends of the substrate 10 along the first direction X and are symmetrically distributed around the central reference 21. This symmetrical layout is to ensure uniform and precise force during the subsequent extrusion operation of the battery module, and to ensure that the two ends of the extruded battery module are also symmetrical about the central reference 21, ensuring that it falls within the range of the corresponding strap 80.

[0066] Each actuator 321 is connected to a corresponding extrusion structure 31. The actuator 321 transmits its own power to the extrusion structure 31, thereby driving the extrusion structure 31 to move along the first direction X. In actual operation, when the device is started, the actuator 321 will run according to the set program, so that the two extrusion structures 31 can move symmetrically towards the battery module around the central reference 21, gradually applying extrusion force to the battery module, thereby achieving precise and uniform extrusion shaping of the battery module. If the layout of the actuator 321 is asymmetrical or there is a problem with the connection, it may cause the movement of the extrusion structure 31 to be uncoordinated, resulting in uneven force on the battery module, affecting the extrusion effect and the final shape and quality of the battery module. Therefore, such a rigorous and symmetrical design of the drive component 32 is of great significance for the efficient and stable operation of the entire device. Specifically, the actuator 321 can be a servo cylinder, which can be pre-set with servo points corresponding to the design length of each type of battery module. When the battery module is extruded, the servo cylinder can move to the corresponding servo point and stop during the extrusion process.

[0067] Reference Figure 1 and Figure 2The driving assembly 32 further includes a connector 322 corresponding to the extrusion structure 31. The driver 321 is disposed at the bottom of the substrate 10. The substrate 10 has an opening 11 that extends vertically. The distance between one end of the opening 11 and the center reference 21 is less than the distance between the slit 221 and the center reference 21. One end of the connector 322 is connected to the extrusion structure 31, and the other end passes through the opening 11 and is connected to the driver 321. The end of the support platform 20 is provided with a clearance notch 23 extending along the first direction X corresponding to the connector 322.

[0068] The actuator 321 is located at the bottom of the substrate 10, making efficient use of space. The substrate 10 has a through-hole 11. One end of the connector 322 is connected to the extrusion structure 31, and the other end passes through the opening 11 of the substrate 10 and connects to the actuator 321. This allows the power generated by the actuator 321 to be effectively transmitted to the extrusion structure 31 via the connector 322, causing the extrusion structure 31 to move along the first direction X, thus performing the extrusion operation on the battery module. This opening 11 extends along the first direction X; however, the distance between its extended end and the center reference 21 is less than the distance between the slit 221 and the center reference 21. This design ensures that the substrate 10 has sufficient space for the connector 322 to move, guaranteeing the extrusion effect.

[0069] Meanwhile, to prevent the connector 322 from interfering with the support platform 20 during movement, a clearance notch 23 extending along the first direction X is specially provided at the end of the support platform 20 corresponding to the connector 322. This clearance notch 23 provides space for the movement of the connector 322, ensuring that the entire drive assembly 32 can operate smoothly when driving the extrusion structure 31, and ensuring that the device can perform the extrusion and shaping of the battery module in an orderly manner, with each component cooperating with each other and working together.

[0070] Reference Figure 3 and Figure 4 It also includes a foolproof component 70, which is located at one end of the clearance notch 23. The strap 80 includes a strap body 81 and a connector 82 that connects and fixes the ends of the strap body 81. The foolproof component has a slot, the width of which is greater than the thickness of the strap body 81 and less than the thickness of the connector 82.

[0071] The error-proof component 70 is located at one end of the clearance notch 23 and has an error-proof function. The error-proof component 70 has a slot that is larger than the thickness of the strap body 81, so that the strap body 81 can be smoothly inserted into the slot without obstruction, facilitating the corresponding installation and arrangement operations in the device. At the same time, the width of the slot is smaller than the thickness of the connector 82, which means that the connector 82 cannot be inserted into the slot.

[0072] When the operator correctly installs the strap 80, the strap body 81 will smoothly insert into the slot; however, if the strap 80 is installed backwards or incorrectly, the connector 82 will be stuck when it touches the slot, preventing further operation. This prompts the operator to correct the error in time, avoiding the impact of incorrect installation of the strap 80 on the subsequent fixing of the battery module and the normal use of the entire extrusion and shaping device. This ensures that each step can be carried out in an orderly manner according to the correct process, improving the accuracy and efficiency of the work.

[0073] Furthermore, the extrusion structure 31 includes a slide 311 and a clamping block 312.

[0074] A slide table 311 is disposed on the substrate 10 along the first direction X, and a mounting surface 3111 is provided at one end of the slide table 311 near the central reference 21. The slide table 311 provides stable support and guidance for the movement of the entire extrusion structure 31. Specifically, the slide table 311 and the substrate 10 are connected and guided by a slide rail assembly. The mounting surface 3111 at the end of the slide table 311 near the central reference 21 is an important foundation for the subsequent installation of the clamping block 312. Its flatness, dimensional accuracy, etc., have a direct impact on the installation of the clamping block 312 and subsequent work.

[0075] A clamping block 312 is disposed on the mounting surface 3111. One end of the clamping block 312 near the central reference 21 has a pressing end face 3121 perpendicular to the first direction X. The clamping block 312 is the component that directly contacts the battery module and applies pressing force. When pressing the battery module, the pressing end face 3121 of the clamping block 312 can contact the module surface at a perpendicular angle, ensuring that the pressing force is applied evenly and perpendicularly to the module. This avoids problems such as uneven force distribution and irregular deformation of the module due to deviations in the pressing angle, helping to achieve precise, stable, and high-quality pressing and shaping effects. This allows the battery module to be adjusted according to design requirements in terms of length, ensuring the normal operation of the entire device and the subsequent good performance of the battery module.
