Description

Technical Field

[0001] The present application relates to the field of semiconductor production equipment, and specifically to a steel strip equipment for assembling battery cell modules. Background Art

[0002] A battery module is made up of multiple stacked cells, each with end plates at either end. To secure the cells and the end plates, two steel strips are typically placed over the module, keeping the cells tightly together.

[0003] Different types of battery modules have different shapes of end plates at both ends, such as Figure 1 In the battery module 100 shown, the lower end of the end plate 300 is provided with a fixing piece extending along the length direction of the battery module 100. Since the steel strip 200 itself does not have obvious elasticity, it is necessary to squeeze and shrink the battery module 100 from both ends through an extrusion mechanism so that the steel strip 200 can be put on the battery module. However, the deformation of the battery module 100 when squeezed is very small. Figure 1 The end plate 300 and the two steel strips 200 can only be put on the battery module 100 from top to bottom.

[0004] During the steel strip application process, the extrusion mechanism continuously compresses both ends of the cell module 100. If the steel strip 200 is positioned below the extrusion end of the mechanism, the mechanism will prevent the steel strip 200 from being applied downwards. For steel strips below the extrusion end, the current method involves wrapping the steel strip around the lower end of the cell module and then welding the two ends together. This current method is complex and inefficient. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a battery cell module extrusion mechanism, which adopts the following technical solutions:

[0006] A steel strip wrapping device for a battery module, comprising a carrying platform, two extrusion mechanisms, a lifting drive mechanism, a lifting bracket and a pressing mechanism, wherein:

[0007] The carrying platform is used to carry the battery cell module, and the two squeezing mechanisms are arranged at both ends of the carrying platform along the first horizontal direction, and the two squeezing mechanisms are configured to squeeze the two ends of the battery cell module on the carrying platform in the length direction from both ends;

[0008] The squeezing mechanism includes a base and at least two squeezing assemblies spaced apart in a vertical direction on the base, each squeezing assembly being capable of independently extending or retracting in a first horizontal direction to squeeze or separate the battery cell module from a corresponding pushing position;

[0009] The lifting bracket is arranged above the carrying platform, the lifting bracket is connected to the driving end of the lifting drive mechanism, the pressing mechanism is arranged on the lifting bracket, and the lifting drive mechanism is configured to drive the lifting bracket to descend so that the pressing mechanism is close to the battery cell module;

[0010] The pressing mechanism is configured to push the steel strip downward to wrap the steel strip around the battery cell module and lower it to a preset position. During the process of lowering the steel strip to the preset position, the steel strip passes through the corresponding pushing positions of each pressing assembly. The pressing assembly is configured to detach from the battery cell module when the steel strip passes the corresponding pushing position to avoid the steel strip.

[0011] After the steel strip passes the corresponding pushing position, the extrusion assembly is reset to re-extrude the battery cell module.

[0012] Through the cooperation of the pressing mechanism and the two extrusion mechanisms, the battery cell module steel strip sheathing equipment provided by the present application can sheath a steel strip onto the battery cell module from the upper side each time. Since the extrusion assembly of the extrusion mechanism can move toward or away from the battery cell module, when the steel strip slides from top to bottom along the battery cell module, each extrusion assembly can implement avoidance of the steel strip, thereby ensuring that the steel strip can slide to the corresponding preset position, and when the steel strip passes the pushing position of each extrusion assembly, the extrusion assembly immediately resumes extruding the battery cell module. In addition, since at least two extrusion assemblies are arranged at intervals in the vertical direction on the extrusion mechanism, when one of the extrusion assemblies detaches from the battery cell module to avoid the steel strip, the other extrusion assemblies continue to squeeze the battery cell module, thereby ensuring that the battery cell module is always in an extruded state during the steel strip sheathing process.

[0013] By using the battery module steel strip equipment provided in this application to install the steel strips, the continuous installation of two or more steel strips required to be installed can be completed in sequence from top to bottom, thereby improving the installation efficiency of the steel strips.

[0014] In some embodiments, the extrusion assembly includes a first driving member, an extrusion plate and two extrusion rods, wherein: the first driving member is mounted on the base, the extrusion plate is slidably mounted on the base along a first horizontal direction, and the two extrusion rods are mounted on the side of the extrusion plate facing the supporting platform; the first driving member is configured to drive the extrusion plate close to or away from the battery cell module on the supporting platform, so that the two extrusion rods squeeze or move away from the battery cell module on the supporting platform; the gap between the two extrusion rods is for the pressing mechanism to pass vertically.

[0015] By configuring the extrusion component of the extrusion assembly as two extrusion rods with a gap between them, the extrusion assembly can squeeze the ends of the cell module from two different positions, ensuring uniform force on the ends of the cell module and preventing pressure loss of the cells within the cell module due to excessive local force. Furthermore, the extrusion assembly can avoid the pressing mechanism, allowing it to pass downward through the extrusion assembly and push the steel strip to a preset position below the extrusion assembly.

[0016] In some embodiments, the extrusion assembly further includes a pushing block, a pushing wheel and a return spring, wherein: the pushing wheel is mounted on the extrusion plate, one end of the return spring is connected to the base, the other end of the return spring is connected to the extrusion plate, and the length direction of the return spring extends along the first horizontal direction; the pushing block is slidably connected to the base and is connected to the driving end of the first driving member, a pushing inclined surface is formed on the pushing block, the pushing wheel on the extrusion plate is pressed against the pushing inclined surface, and the first driving member is configured to drive the pushing block to slide back and forth along the second horizontal direction, so that the pushing block moves between the pushing position and the release position. When the first driving member drives the pushing block to slide from the pushing position toward the pushing position, the pushing inclined surface of the pushing block pushes the extrusion plate to slide along the first horizontal direction toward the battery cell module via the push wheel, so as to drive the two extrusion rods to squeeze the ends of the battery cell module, and the return spring extends under the traction of the extrusion plate; when the first driving member drives the pushing block to slide from the pushing position toward the releasing position, the pushing inclined surface of the pushing block gradually disengages from the push wheel, and the return spring loses pressure and retracts, so as to drive the extrusion plate to move away from the battery cell module along the first horizontal direction.

[0017] By providing a pushing block, a pushing wheel and a return spring, the first driving member pushes the pushing block perpendicularly to the length direction of the battery cell module. The pushing block pushes the pushing wheel on the extrusion plate via the pushing slope thereon, thereby pushing the extrusion plate to extrude the battery cell module in parallel to the length direction of the battery cell module. Compared to the existing extrusion method of directly driving the extrusion plate to extrude the battery cell module in parallel to the length direction of the battery cell module, the first driving member only needs to output a smaller thrust to achieve the same extrusion effect on the battery cell module, thereby reducing the equipment cost. In addition, the reaction force of the battery cell module is mainly applied to the base, and the reaction force from the battery cell module borne by the first driving member is reduced, thereby reducing the risk of damage to the first driving member and extending the service life of the extrusion mechanism.

[0018] In some embodiments, the pressing mechanism includes two pressing components arranged at both ends of the lifting bracket in the length direction, and the two pressing components are configured to respectively support two opposite first side edges of the steel belt, and the first side edges are perpendicular to the first horizontal direction.

[0019] After the two pressing components respectively support the two opposite first side edges of the steel belt, they are driven by the lifting bracket to simultaneously press down the two first side edges of the steel belt. In this way, the steel belt can be ensured to slide downward smoothly in a horizontal state until it reaches the preset position, preventing the steel belt from tilting during the sliding process and preventing the steel belt from getting stuck with the side edges of the battery cell module during the sliding process.

[0020] In some embodiments, the pressing assembly includes a second driving member, a connecting plate and a pressing block, wherein: the second driving member is arranged on the lifting bracket, the connecting plate is connected to the driving end of the second driving member, the pressing block is arranged on the connecting plate, and the gap between the two extrusion rods is for the connecting plate and the pressing block to pass vertically; when the lifting drive mechanism drives the lifting bracket to descend into place, the second driving member is configured to drive the connecting plate to descend, so as to drive the pressing block to push the first side of the steel strip downward.

[0021] A pressing assembly with a simple structure is provided, which drives the connecting plate and the pressing block thereon to descend by a second driving member, so that the pressing block can push the first side of the steel belt downward during the descent process. In addition, the connecting plate and the pressing block thereon can pass through the gap between the two extrusion rods until the pressed steel belt is pushed to a preset position. In some embodiments, the pressing assembly further includes a supporting member provided on the connecting plate, the supporting member is located below the pressing block, the steel belt is located between the supporting member and the pressing block, and the supporting member is configured to prevent the steel belt from deviating from the preset position; the pressing assembly further includes a third driving member, the third driving member is provided at the bottom of the connecting plate, and the supporting member is mounted on the driving end of the third driving member; the third driving member is configured to drive the supporting member to translate toward the steel belt to prevent the steel belt from deviating from the pressing assembly; the third driving member is also configured to drive the supporting member away from the steel belt to avoid the steel belt.

[0022] By arranging a supporting member below the pressing block on the connecting plate, when the pressing block pushes the steel strip downward, the supporting member can implement support and limit the steel strip to prevent the steel strip from sliding down excessively and deviating from the preset position.

[0023] In some embodiments, the extrusion mechanism also includes a base and a clamping assembly, and the base is slidably installed on the base along the first horizontal direction; the clamping assembly includes a clamping plate and a clamping spring, and the clamping plate is installed at the bottom end of the base and extends along the first horizontal direction, the first end of the clamping spring is connected to the base, and the second end of the clamping spring is connected to the base, and the clamping end of the clamping plate on the base is continuously pressed against the end of the battery cell module on the supporting platform under the pressure of the clamping spring.

[0024] The base is slidably installed on the base, and a clamping assembly is provided. When it is necessary to implement the extrusion of the battery cell module, the base is first controlled to move to the target position close to the battery cell module, so that the clamping end of the clamping plate on the base can be continuously pressed on the end of the battery cell module under the pressure of the clamping spring, so as to implement the fixed positioning pre-positioning of the end of the battery cell module, thereby facilitating the extrusion assembly to implement the extrusion of the battery cell module. In addition, the clamping assembly is continuously pressed on the end of the battery cell module during the process of wrapping the steel strip, that is, the clamping assembly can cooperate in the implementation of the extrusion of the battery cell module, thereby increasing the extrusion force of the extrusion mechanism on the battery cell module. In addition, when the base moves to the target position close to the battery cell module and the clamping assembly is pressed on the end of the battery cell module, the extrusion assembly is already close to the battery cell module, so the extrusion assembly only needs to move a small stroke toward the battery cell module to implement the extrusion of the battery cell module.

[0025] In some embodiments, the bases of the two extrusion mechanisms are respectively slidably installed on the two ends of the supporting platform along the first horizontal direction, and the battery cell module steel strip wrapping equipment also includes two translation drive mechanisms corresponding to the two extrusion mechanisms one by one, and the driving ends of the two translation drive mechanisms are respectively fixedly connected to the bases of the two extrusion mechanisms; the two translation drive mechanisms are configured to synchronously drive the two extrusion mechanisms to slide closer to the supporting platform, so that the two extrusion mechanisms are close to the battery cell module located on the supporting platform.

[0026] By providing a translation drive mechanism corresponding to the two extrusion mechanisms one by one, the two extrusion mechanisms are automatically driven, so that the two extrusion mechanisms are moved closer to or away from the battery cell module located on the supporting platform.

[0027] In some embodiments, the battery module steel strip wrapping equipment also includes a spreading mechanism, which is installed on a lifting bracket and is configured to receive the steel strip; the spreading mechanism includes two spreading components arranged at both ends of the lifting bracket, and the two spreading components are configured to move away from each other along a first horizontal direction to tighten the received steel strip; the pressing mechanism is configured to push downward the steel strip tightened by the spreading mechanism.

[0028] The spreading mechanism receives the steel strip and tightens the received steel strip, so that when the pressing mechanism pushes the steel strip downward, the steel strip can be smoothly put down onto the battery module.

[0029] In some embodiments, the support assembly includes a fourth drive member, a movable plate and two support rods, wherein: the fourth drive member is arranged on the lifting bracket, the movable plate is slidably connected to the lifting bracket and is connected to the driving end of the fourth drive member, and the two support rods are arranged at intervals along the second horizontal direction at the end of the movable plate, and the support rods extend in the vertical direction, and the second horizontal direction is perpendicular to the first horizontal direction; the fourth drive member is used to drive the movable plate to slide along the first horizontal direction to drive the two support rods from the inner side of the steel belt to press against the first side edge of the steel belt.

[0030] A simple-structured expansion assembly is provided. A fourth drive member drives two expansion rods to slide along a first horizontal direction, thereby causing the two expansion rods to move from the inner side of a steel strip against a first side edge of the steel strip. Initially, the two expansion rods of the expansion assembly are in a retracted position near a lifting bracket. The distance between the two expansion rods at the first end of the lifting bracket and the two expansion rods at the first end of the lifting bracket is less than the length of the second side edge of the steel strip, thereby allowing the expansion rods of the two expansion assemblies to extend into the steel strip to receive the steel strip. Subsequently, the fourth drive member drives the two expansion rods at the first end of the lifting bracket to extend away from the lifting bracket toward the first side of the lifting bracket. Simultaneously, the fourth drive member drives the two expansion rods at the second end of the lifting bracket to extend away from the lifting bracket toward the second side of the lifting bracket. This results in the two opposing first side edges of the steel strip being tightened.

[0031] In some embodiments, the steel strip wrapping equipment for battery cell modules further includes a first guide mechanism arranged on a lifting bracket; when the pressing mechanism pushes the steel strip downward, the first guide mechanism supports from the inside and guides the two opposite second side edges of the steel strip in the vertical direction, so that the steel strip is wrapped around the battery cell module along the first guide mechanism, and the second side edges are parallel to the first horizontal direction.

[0032] There is a height difference between the steel strip located above the cell module, for example, the steel strip held tight against the expansion assembly, and the cell module. By providing a first guide mechanism, the steel strip located above the cell module, for example, the steel strip held tight against the expansion assembly, can smoothly transition from above the cell module to the top of the cell module under the guidance and support of the first guide mechanism.

[0033] In some embodiments, the first guide mechanism includes two first guide assemblies arranged at both ends of the lifting bracket, the two first guide assemblies cooperate to support and guide the two second side edges of the steel belt from both ends, the first guide assembly includes a fifth drive member, a first guide block and a second guide block, wherein: the fifth drive member is arranged on the lifting bracket, the first guide block and the second guide block are relatively installed on the two driving ends of the fifth drive member along the second horizontal direction, the fifth drive member is used to drive the first guide block and the second guide block to slide closer to the middle or slide apart to both sides to adjust the distance between the first guide block and the second guide block, and the second horizontal direction is perpendicular to the first horizontal direction; when the lifting drive mechanism drives the lifting bracket to descend into place, the first guide block and the second guide block are tightly attached to the two side edges of the battery cell module, and when the pressing mechanism pushes the steel belt downward, the first guide block and the second guide block support and guide the two second side edges of the steel belt from the inside, so that the steel belt is put on the battery cell module.

[0034] By configuring the first guide mechanism to include two first guide assemblies, the two first guide assemblies cooperate to support and guide the two second side edges of the steel strip from both ends. This ensures the steel strip's second side edges are properly guided, allowing it to slide smoothly down and transition onto the battery module while preventing it from tilting. By configuring the first guide assembly to include a fifth drive member, a first guide block, and a second guide block, the first guide assembly can both guide the steel strip and avoid it. Specifically, in the initial state, the first and second guide blocks converge toward the center, avoiding the steel strip and allowing it to be received and braced by the spreading assembly. Subsequently, the fifth drive member drives the first and second guide blocks to slide apart, aligning the spacing between them to match the width of the battery module. The first and second guide blocks support the two second side edges of the steel strip from the inside. Finally, the lifting drive mechanism lowers the lifting bracket into position, placing the first and second guide blocks firmly against the edges of the battery module. In this way, when the pressing mechanism pushes the steel strip downward, the first guide block and the second guide block guide the two second side edges of the steel strip from the inside, and finally the steel strip is put onto the battery module.

[0035] In some embodiments, the battery module steel strip wrapping equipment further includes a second guide mechanism disposed on the lifting bracket; when the pressing mechanism pushes the steel strip downward, the second guide mechanism is configured to support and guide the two opposite first side edges of the steel strip from the inside, so that the steel strip slides downward to a preset position under the guidance of the second guide mechanism, and the first side edge is perpendicular to the first horizontal direction.

[0036] By setting up a second guide mechanism, when the pressing mechanism pushes the steel belt downward, the second guide mechanism supports and guides the two opposite first side edges of the steel belt from the inside, so that the steel belt slides downward to a preset position under the guidance of the second guide mechanism, preventing the steel belt from getting stuck and tilting during the sliding process.

[0037] In some embodiments, the second guide mechanism includes two second guide assemblies arranged at both ends of the lifting bracket, and the two second guide assemblies respectively support and guide the two first side edges of the steel belt from the outside of both ends of the battery cell module; the second guide assembly includes a second lifting drive and a guide plate, the second lifting drive is arranged on the lifting bracket, and the guide plate is connected to the driving end of the second lifting drive; the second lifting drive is used to drive the guide plate to descend so that the guide plate is tightly attached to the end face of the battery cell module in the length direction.

[0038] By configuring the second guide mechanism to include two second guide assemblies, the two second guide assemblies cooperate to support and guide the two first side edges of the steel strip from both ends, thereby ensuring the guiding effect on the two first side edges of the steel strip, ensuring that the steel strip can smoothly descend to the preset position along the battery module, and preventing the steel strip from tilting or getting stuck during the descent. By configuring the second guide assembly, the second guide assembly can support and guide one first side edge of the steel strip from the outside of one end of the battery module. Specifically, before the pressing mechanism pushes the steel strip downward, the second lifting drive member drives the guide plate to descend, so that after the guide plate passes through the steel strip, it descends close to the end face of the battery module until the lower end of the guide plate reaches the preset position. In this way, when the pressing mechanism pushes the steel strip downward, the two first side edges of the steel strip slide downward under the guidance of the guide plates at the two end faces of the battery module until they reach the preset position.

[0039] In some embodiments, the battery cell module steel strip wrapping equipment further comprises a pressure plate lifting drive mechanism provided at the bottom of the lifting bracket, which drives the lifting bracket to descend into position, and the pressure block is pressed against the upper surface of the battery cell module.

[0040] By setting a pressure plate at the bottom of the lifting bracket, when the lifting drive mechanism drives the lifting bracket down into place, the pressure block can press the battery cell module downward, thereby further ensuring that the battery cell module remains fixed during the steel strip sheathing process.

DETAILED DESCRIPTION

[0052] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0053] like Figures 2 to 6 As shown, the battery module steel strip wrapping equipment in the embodiment of the present application includes a carrying platform 1, two extrusion mechanisms 2, a lifting drive mechanism 3, a lifting bracket 4 and a pressing mechanism, wherein:

[0054] The carrier 1 is used to carry the battery cell module 100. Two squeezing mechanisms 2 are arranged at both ends of the carrier 1 along the first horizontal direction. The two squeezing mechanisms 2 are configured to squeeze the battery cell module 100 on the carrier 1 from both ends in the length direction. Figure 1 As shown in , the first horizontal direction and the length direction of the battery cell module 100 are both X-axis directions.

[0055] The squeezing mechanism 2 includes a base 21 and at least two squeezing assemblies 22 vertically spaced apart on the base 21 . Each squeezing assembly 22 can independently extend or retract along a first horizontal direction to squeeze or detach the battery cell module 100 from a corresponding pushing position. Figures 3 to 5The extrusion mechanism 2 in the illustrated embodiment is provided with two extrusion assemblies 22 . Of course, in other embodiments, the extrusion mechanism 2 may also be provided with three, four or other numbers of extrusion assemblies 22 .

[0056] The lifting bracket 4 is arranged above the supporting platform 1, and the lifting bracket 4 is connected to the driving end of the lifting drive mechanism 3. The pressing mechanism is arranged on the lifting bracket 4. The lifting drive mechanism 3 is configured to drive the lifting bracket 4 to descend so that the pressing mechanism is close to the battery cell module 100.

[0057] After the lift drive mechanism 3 lowers the lift bracket 4 into position, the pressing mechanism is configured to push downward on the steel strip 200 to be installed, wrapping the steel strip 200 around the battery module 100 and lowering it to a predetermined position. As the steel strip descends to its predetermined position, it passes through the corresponding pressing positions of the pressing assemblies 22. The pressing assemblies 22 are configured to disengage from the battery module when the steel strip passes the corresponding pressing position, thus clearing the steel strip 200.

[0058] After the steel strip 200 passes the corresponding pressing position, the pressing assembly 22 is reset to press the battery cell module 100 again.

[0059] The following description of the steel strip wrapping process of the steel strip wrapping apparatus for the battery cell module in the embodiment of the present application will be exemplified by taking the case where two steel strips 200 need to be wrapped around a battery cell module 100, and the extrusion mechanism 2 includes two extrusion assemblies 22. It should be noted that because the structures and operation processes of the two extrusion mechanisms 2 are identical, the following description of the steel strip wrapping process of the battery cell module will only describe the detailed operation process of one of the extrusion mechanisms 2.

[0060] The optional steel strip wrapping process for the battery cell module in the embodiment of the present application is as follows:

[0061] First, the battery cell module 100 is loaded onto the carrier 1 , and the two extrusion mechanisms 2 are controlled to move toward the carrier 1 so that the two extrusion mechanisms 2 are close to both end faces of the battery cell module 100 along the length direction.

[0062] Subsequently, the two extrusion components 22 of the extrusion mechanism 2 are controlled to extend toward the battery cell module 100, so that the two extrusion components 22 of the extrusion mechanism 2 press the end surface of the battery cell module 100 from corresponding pressing positions. Of course, the pressing position of the first extrusion component 22 located at the top is higher than the pushing position of the second extrusion component 22 located at the bottom.

[0063] Next, the first steel strip to be installed is fed to the initial position between the battery module 100 and the pressing mechanism, and the lifting drive mechanism 3 drives the lifting bracket 4 to descend, so that the pressing mechanism is close to the first steel strip and the battery module 100 .

[0064] Subsequently, the pressing mechanism begins to push the first steel strip downward, so that the first steel strip is placed on the battery cell module 100 and then slides down along the side wall of the battery cell module 100 until it reaches the corresponding first preset position. The first preset position is located below the pushing position of the second extrusion assembly 22.

[0065] During the downward movement of the first steel strip, the first steel strip needs to successively pass over the pushing position of the first extrusion assembly 22 and the pushing position of the second extrusion assembly 22. Specifically, when the first steel strip is about to reach the pushing position of the first extrusion assembly 22, the first extrusion assembly 22 retracts away from the battery cell module 100 to detach from the battery cell module 100, thereby avoiding the first steel strip. After the first steel strip passes over the pushing position of the first extrusion assembly 22, the first extrusion assembly 22 extends again to resume extrusion of the battery cell module 100. Similarly, when the first steel strip is about to reach the pushing position of the second extrusion assembly 22, the second extrusion assembly 22 retracts away from the battery cell module 100 to detach from the battery cell module 100, thereby avoiding the first steel strip. After passing over the pushing position of the second extrusion assembly 22, the first steel strip reaches the first preset position, at which point the installation of the first steel strip is completed.

[0066] The pressing mechanism is controlled to rise to its initial position, and the lifting drive mechanism 3 drives the lifting bracket 4 to rise and return to its original position. The second steel strip to be installed is brought into the initial position between the battery cell module 100 and the pressing mechanism. Subsequently, the lifting drive mechanism 3 drives the lifting bracket 4 to descend, bringing the pressing mechanism closer to the second steel strip and battery cell module 100.

[0067] Next, the pressing mechanism begins to push the second steel strip downward, so that after the second steel strip is placed on the battery module 100, it slides down along the side wall of the battery module 100 until it reaches the corresponding second preset position. The second preset position is located between the pushing positions of the first and second pressing assemblies 22.

[0068] During the downward movement, the second steel strip passes the pressing position of the first extrusion assembly 22. When the second steel strip is about to reach the pressing position of the first extrusion assembly 22, the first extrusion assembly 22 retracts away from the battery module 100 to disengage from the battery module 100, thereby avoiding the second steel strip. After the second steel strip passes the pressing position of the first extrusion assembly 22, it reaches the second preset position, completing the installation of the second steel strip. The pressing mechanism is controlled to return to its initial state, and the lifting drive mechanism 3 drives the lifting bracket 4 to rise and return to its original position.

[0069] Subsequently, the two extrusion assemblies 22 of the extrusion mechanism 2 are controlled to retract away from the battery cell module 100 to release the battery cell module 100. Finally, the two extrusion mechanisms 2 are controlled to move away from the carrier 1 and return to their original positions to facilitate the unloading device to unload the battery cell module 100 with the steel strip from the carrier 1.

[0070] It can be seen that, through the cooperation of the pressing mechanism and the two extrusion mechanisms 2, the battery module steel strip sheathing equipment in the embodiment of the present application can each sheath a steel strip from top to bottom onto the battery module 100. Since each extrusion assembly 22 of the extrusion mechanism 2 can independently move toward or away from the battery module 100, when the steel strip slides from top to bottom along the battery module 100 under the pressure of the pressing mechanism, each extrusion assembly 22 can avoid the steel strip, thereby ensuring that the steel strip can slide downward to the corresponding preset position.

[0071] In addition, since at least two extrusion components 22 are arranged at intervals in the vertical direction on the extrusion mechanism 2, when one of the extrusion components 22 detaches from the battery cell module 100 to avoid the steel strip, the other extrusion components 22 continue to squeeze the battery cell module 100, thereby ensuring that the battery cell module 100 is always in an extruded state during the steel strip assembly process, and ultimately allowing the steel strip to slide down smoothly.

[0072] By using the battery module steel strip equipment provided in the embodiment of the present application to install the steel strip, the continuous installation of two or more steel strips required to be installed can be completed in sequence from top to bottom, thereby improving the installation efficiency of the steel strip.

[0073] The lifting drive mechanism 3 in the embodiment of the present application can adopt various existing linear drive modules that can drive the lifting bracket 4 to move up and down, such as a cylinder drive module, a screw motor drive module, etc.

[0074] like Figures 3 to 5 As shown, the extrusion assembly 22 optionally includes a first driving member 221, an extrusion plate 222, and two extrusion rods 223. The first driving member 221 is mounted on the base 21, the extrusion plate 222 is slidably mounted on the base 21 along a first horizontal direction, and the two extrusion rods 223 are mounted on the side of the extrusion plate 222 facing the carrier 1. The first driving member 221 is configured to drive the extrusion plate 222 toward or away from the battery cell module 100 on the carrier 1, so that the two extrusion rods 223 extrudes or moves away from the battery cell module 100 on the carrier 1. The gap between the two extrusion rods 223 allows the pressing mechanism to pass vertically.

[0075] By configuring the extrusion component of the extrusion assembly 22 as two extrusion rods 223 with a gap between them, the extrusion assembly 22 can, on the one hand, extrusion the battery cell module 100 from two different positions, so that the ends of the battery cell module 100 are evenly stressed, preventing the battery cells within the battery cell module 100 from suffering pressure damage due to localized excessive stress. On the other hand, the gap between the two extrusion rods 223 of the extrusion assembly 22 allows the pressing mechanism to avoid the pressure, allowing the pressing mechanism to pass downward through the extrusion assembly 22 and push the steel strip 200 to a predetermined position below the extrusion assembly 22.

[0076] The first driving member may be any existing linear driving module capable of driving the extrusion plate 222 to slide along the first horizontal direction, such as a cylinder or a screw motor.

[0077] As those skilled in the art are aware, in existing extrusion assemblies, the first driver (e.g., a cylinder) drives the extrusion member along the length of the cell module to compress the cell module. This extrusion assembly structure requires the first driver to possess a high thrust, which increases equipment costs. Furthermore, the first driver is subject to significant reaction from the cell module, making it susceptible to damage.

[0078] In order to overcome the above technical defects of the existing extrusion components, Figures 3 to 5 As shown, optionally, the extrusion assembly 22 also includes a pushing block 224, a pushing wheel 225 and a return spring 226, wherein: the pushing wheel 225 is installed on the extrusion plate 222, one end of the return spring 226 is connected to the base 21, and the other end of the return spring 226 is connected to the extrusion plate 222, and the length direction of the return spring 226 extends along the first horizontal direction.

[0079] The pushing block 224 is slidably connected to the base 21 and is connected to the driving end of the first driving member 221. The pushing block 224 is formed with a pushing inclined surface 227, and the pushing wheel 225 on the extrusion plate 222 presses against the pushing inclined surface 227. The first driving member 221 is configured to drive the pushing block 224 to slide back and forth along a second horizontal direction (the Y-axis direction in the figure) so that the pushing block 224 switches between a pushing position and a released position. The second horizontal direction is perpendicular to the first horizontal direction.

[0080] When the first driving member 221 drives the pushing block 224 to slide from the release position toward the pushing position, the pushing inclined surface 227 of the pushing block 224 pushes the extrusion plate 222 to slide along the first horizontal direction toward the battery cell module 100 via the pushing wheel 225, thereby driving the two extrusion rods 223 on the extrusion plate 222 to compress the end of the battery cell module 100. During this process, the return spring 226 is stretched and deformed under the pull of the extrusion plate 222.

[0081] When the first driving member 221 drives the pushing block 224 to slide from the pushing position toward the releasing position, the pushing inclined surface 227 of the pushing block 224 gradually separates from the pushing wheel 225, and the return spring 226 loses pressure and retracts, thereby driving the extrusion plate 222 to slide and reset away from the battery cell module 100 along the first horizontal direction, and the two extrusion rods 223 separate from the end of the battery cell module 100.

[0082] It can be seen that by setting the pushing block 224, the pushing wheel 225 and the return spring 226, the first driving member 221 pushes the pushing block 224 perpendicular to the length direction of the battery cell module 100, and the pushing block 224 pushes the pushing wheel 225 on the extrusion plate 222 via the pushing inclined surface 227 thereon, thereby pushing the extrusion plate 222 to extrude the battery cell module 100 parallel to the length direction of the battery cell module 100.

[0083] Compared to conventional systems that directly drive the extrusion plate 222 to compress the cell module 100 parallel to its length, the first drive member 221 only needs to output a smaller thrust to achieve the same extrusion effect on the cell module 100, thereby reducing equipment costs. Furthermore, the reaction force of the cell module 100 is primarily exerted on the base 21, reducing the reaction force borne by the first drive member 221 from the cell module 100. This reduces the risk of damage to the first drive member 221 and extends the service life of the extrusion mechanism.

[0084] like Figures 3 to 5 As shown, optionally, the extrusion mechanism 2 further includes a base 23 and a pressing assembly 24, and the base 21 is slidably mounted on the base 23 along the first horizontal direction. The pressing assembly 24 includes a pressing plate 242 and a pressing spring 241. The pressing plate 242 is mounted on the bottom end of the base 21 and extends along the first horizontal direction. The first end of the pressing spring 241 is connected to the base 23, and the second end of the pressing spring 241 is connected to the base 21. Under the pressure of the pressing spring 241, the pressing end of the pressing plate 241 on the base 21 continuously presses the end of the battery cell module 100 on the supporting platform 1.

[0085] The base 21 is slidably mounted on the base 23 and a pressing assembly 24 is provided. When the battery module 100 on the carrier 1 needs to be pressed, the base 23 is first controlled to move to a target position close to the battery module 100, so that the pressing end of the pressing plate 242 on the base 21 is continuously pressed against the end of the battery module 100 under the pressure of the pressing spring 241, thereby fixing the end of the battery module 100 in position.

[0086] On the one hand, the pressing assembly 24 pre-positions the cell module, thereby facilitating the extrusion of the cell module 100 by the extrusion assembly 22. Furthermore, the pressing assembly 24 continuously presses the end of the cell module 100 during the steel strip wrapping process, i.e., the pressing assembly 24 cooperates in the extrusion of the cell module 100, thereby increasing the extrusion force of the extrusion mechanism 2 on the cell module 100.

[0087] In addition, when the pressing assembly 24 is pressed against the end of the cell module 100 , the extrusion assembly 22 is already close to the cell module 100 . Therefore, the extrusion assembly 22 only needs to move a small distance toward the cell module 100 to extrude the end of the cell module 100 .

[0088] Optional, such as Figure 3 As shown, when the push block 224 is in the released position, the pressing end of the pressing plate 242 protrudes from the ends of the two squeezing rods 223 in the first horizontal direction. This ensures that when the base 23 moves to the target position close to the battery cell module 100, the pressing end of the pressing plate 242 continues to be pressed against the end of the battery cell module 100 under the pressure of the pressing spring 241, while the squeezing end of the squeezing rod 223 has not yet contacted the battery cell module 100, and there is a movable space between the squeezing rod 223 and the battery cell module. That is, after the squeezing rod 223 is pressed against the end of the battery cell module 100, the squeezing rod 223 can extend toward the battery cell module to squeeze the end of the battery cell module 100, and retract away from the battery cell module 100 to detach from the end of the battery cell module 100.

[0089] In order to prevent the pressing assembly 24 from blocking the downward movement of the steel strip 200, the pressing assembly 24 is located below the preset position of the steel strip 200 to be installed. For example, the pressing position of the pressing assembly 24 is located on the end plate at the end of the battery module 100. Of course, in order to prevent the pressing assembly 24 from contacting the pressing mechanism, such as Figure 3 As shown, optionally, two pressing rods are provided at the pressing end of the pressing plate 242, and the pressing plate 242 compresses the end of the battery cell module 100 through the two pressing rods. The gap between the two pressing rods can avoid the pressing mechanism, thereby preventing contact with the pressing mechanism.

[0090] like Figure 2 and Figure 4 As shown, optionally, the bases 23 of the two extrusion mechanisms 2 are slidably mounted on the two ends of the support platform 1 along the first horizontal direction. Correspondingly, the battery module steel strip wrapping equipment in the embodiment of the present application also includes two translation drive mechanisms 6 corresponding to the two extrusion mechanisms 2, and the driving ends of the two translation drive mechanisms 6 are fixedly connected to the bases 23 of the two extrusion mechanisms 2 in a one-to-one manner.

[0091] The two translation drive mechanisms 6 are configured to synchronously drive the two extrusion mechanisms 2 to slide toward the carrier platform 1 , so that the two extrusion mechanisms 2 approach the battery cell module 100 located on the carrier platform from both sides.

[0092] The translation drive mechanism 6 can adopt an existing linear drive module that can drive the extrusion mechanism 2 to slide toward or away from the support platform 1. For example, the translation drive mechanism 6 includes a screw motor, a guide rail extending along the first horizontal direction and a screw. The base 23 is slidably connected to the guide rail and fixedly connected to the screw nut on the screw. When the screw motor drives the screw to rotate, the screw nut drives the base 23 to slide along the guide rail, thereby driving the extrusion mechanism 2 to slide toward or away from the support platform 20. Of course, the translation drive mechanism 6 can also adopt a linear drive module with other structures such as a cylinder drive module.

[0093] like Figure 2 and Figure 6 As shown, the pressing mechanism optionally includes two pressing assemblies 5 disposed at both ends of the lifting bracket 4 in the longitudinal direction (e.g., the X-axis direction in the figure). The two pressing assemblies 5 are configured to respectively support two opposing first side edges of the steel strip 200, where the first side edges are perpendicular to the first horizontal direction. For example, the first side edges are the short sides of the steel strip 200, that is, the two pressing assemblies 5 are configured to respectively support the two short sides of the steel strip 200 and simultaneously push the two short sides of the steel strip 200 downward.

[0094] After the two pressing components 5 respectively support the two opposite first side edges of the steel belt 200, they are driven by the lifting bracket 4 to simultaneously press down the two first side edges of the steel belt 200. In this way, it can ensure that the steel belt 200 slides downward smoothly in a horizontal state until it reaches the preset position, preventing the steel belt 200 from tilting during the sliding process and causing jamming.

[0095] like Figures 7 and 8 and Figure 10 As shown, the pressing assembly 5 optionally includes a second driving member 51, a connecting plate 52, and a pressing block 53. The second driving member 51 is mounted on the lifting bracket 4, the connecting plate 52 is connected to the driving end of the second driving member 51, and the pressing block 53 is mounted on the connecting plate 52. The gap between the two extrusion rods 223 allows the connecting plate 52 and the pressing block 53 to pass vertically. When the lifting drive mechanism 3 drives the lifting bracket 4 to descend into position, the second driving member 51 is configured to drive the connecting plate 52 downward, thereby driving the pressing block 53 to push downward on the first side edge of the steel strip 200.

[0096] Optionally, a pressing groove is provided at the bottom of the pressing block 53, and the second driving member 51 is configured to drive the connecting plate 52 to descend, so that the pressing block 53 is pressed on the upper edge of the steel belt 200 through the pressing groove, thereby ensuring that the pressing block 53 can remain stably on the steel belt 200 during the process of pushing the steel belt 200 downward, and preventing the pressing block 53 from slipping off the steel belt 200.

[0097] like Figure 8 As shown, in order to improve the uniformity of force applied to the first side of the steel strip 200 and prevent the first side of the steel strip 200 from tilting during the downward movement, which could cause a jam, the pressing assembly 5 optionally includes two pressing blocks 53, which are arranged side by side on the connecting plate 52 along the second horizontal direction. When the second driving member 51 drives the connecting plate 52 downward, the two pressing blocks 53 simultaneously press down the first side of the steel strip 200 from two different positions.

[0098] The second driving member 51 can adopt various existing linear driving modules that can drive the connection plate 52 to move up and down, such as a cylinder, a screw motor, etc.

[0099] Optionally, the pressing assembly 5 further includes a supporting member 54 provided on the connecting plate 52 , and the supporting member 54 is located below the pressing block 53 . Figure 8 In the illustrated embodiment, the press-fit assembly 5 has two pressing blocks 53 mounted on the connecting plate 52. Two corresponding supporting members 54 are also provided, with one supporting member 54 positioned directly below each pressing block 53. The first side edge of the steel strip 200 is positioned between the supporting members 54 and the pressing blocks 53. The supporting members 54 are used to support the steel strip 200 from below to prevent it from moving out of its pre-set position.

[0100] The press assembly 5 further includes a third driving member 55, which is disposed at the bottom of the connecting plate 52. The supporting member 54 is mounted on the driving end of the third driving member 55. The third driving member 55 is configured to drive the supporting member 54 to translate toward the steel strip 200 to prevent the steel strip 200 from escaping the press assembly 5. The third driving member 55 is also configured to drive the supporting member 54 away from the steel strip 200 to avoid the steel strip 200.

[0101] By providing a support member 54 below the pressing block on the connecting plate 52, when the pressing block 53 pushes the steel strip 200 downward, the support member 54 can implement a support limit for the steel strip 200, preventing the steel strip 200 from separating from the pressing assembly 5 and deviating from the preset position. When the pressing assembly 5 needs to rise back to its original position, the third driving member 55 drives the support member 54 away from the steel strip 200, avoiding the steel strip 200 and preventing the support member 54 from affecting the rise of the pressing assembly 5.

[0102] The supporting member 54 can be, for example, a supporting plate arranged in a horizontal direction. The third driving member 55 can adopt various existing linear driving modules capable of driving the connecting plate 52 to move up and down, such as a cylinder, a screw motor, etc.

[0103] Optionally, the steel strip wrapping apparatus for cell modules in the embodiment of the present application further includes a spreading mechanism mounted on the lifting bracket 4 and configured to receive the steel strip 200. Specifically, the steel strip 200 to be installed is received and tightened by the spreading mechanism, and the pressing mechanism pushes downward on the steel strip tightened by the spreading mechanism, thereby enabling the steel strip to be smoothly wrapped around the cell module 100.

[0104] like Figure 6 As shown, optionally, the spreading mechanism includes two spreading components 7 provided at both ends of the lifting bracket 4 , and the two spreading components 7 are configured to move away from each other along a first horizontal direction to tightly support the received steel belt 200 .

[0105] like Figure 9 As shown, the expansion assembly 7 optionally includes a fourth drive member 71, a movable plate 72, and two support rods 73. The fourth drive member 71 is mounted on the lifting bracket 4. The movable plate 72 is slidably connected to the lifting bracket 4 and connected to the driving end of the fourth drive member 71. Two support rods 73 are spaced apart at the ends of the movable plate 72 along the second horizontal direction and extend vertically. The fourth drive member 71 is used to drive the movable plate 72 to slide along the first horizontal direction, thereby driving the two support rods 73 from the inner side of the steel strip 200 to abut against the first side edge of the steel strip. The first side edge of the steel strip is generally the short side of the steel strip.

[0106] The optional tightening process of the second side edge of the steel strip by the stretching assembly 7 is as follows:

[0107] In the initial state, the two struts 73 of the support assembly 7 are in a retracted position close to the lifting bracket 4. The distance between the two struts 73 of the support assembly 7 at the first end of the lifting bracket 4 and the two struts 73 of the support assembly 7 at the second end of the lifting bracket 4 is less than the length of the second side of the steel belt 200 (generally the long side of the steel belt), so that the two struts 73 of the support assembly 7 can extend into the steel belt 200 to receive the steel belt 200.

[0108] Subsequently, the fourth driving member 71 drives the two support rods 73 of the expansion assembly 7 at the first end of the lifting bracket 4 away from the lifting bracket 4 and extends toward the first side of the lifting bracket 4. Simultaneously, the fourth driving member 71 drives the two support rods 73 of the expansion assembly 7 at the second end of the lifting bracket 4 away from the lifting bracket 4 and extends toward the second side of the lifting bracket 4. In this way, the two opposing second side edges of the steel belt 200 are respectively braced by the two support rods 73.

[0109] Optionally, the distance between the two struts 73 of the spreading assembly 7 is equivalent to the length of the first side of the steel strip 200. In this way, when the fourth driving member 71 drives the movable plate 72 to slide along the first horizontal direction, the two struts 73 can respectively press the two corners of the steel strip from the inside.

[0110] Through the cooperation of the four support rods 73 of the two support assemblies 7, the four corners of the steel strip 200 are each pressed by a support rod 73, so that the four side edges of the steel strip 200 are finally supported.

[0111] The fourth driving member 71 can adopt various existing linear driving modules that can drive the movable plate 72 to slide along the first horizontal direction, such as a cylinder, a screw motor, etc.

[0112] Optionally, the steel strip wrapping apparatus for cell modules in the embodiment of the present application further includes a first guide mechanism disposed on the lifting bracket 4. When the pressing mechanism pushes the steel strip 200 downward, the first guide mechanism supports and vertically guides the two opposing second side edges of the steel strip 200 from the inside, allowing the steel strip 200 to be wrapped around the cell module 100 along the first guide mechanism. The second side edges are generally the long sides of the steel strip 200.

[0113] By providing the first guide mechanism, the steel strip 200 located above the battery module 100, for example, the steel strip 200 stretched on the expansion assembly 7, can be smoothly transferred to the battery module 100 under the guidance and support of the first guide mechanism.

[0114] like Figure 6 、 Figure 9 Right now Figure 10 As shown, the first guide mechanism optionally includes two first guide assemblies 8 disposed at both ends of the lifting bracket 4. The two first guide assemblies 8 cooperate to support and guide the two second side edges of the steel strip 200 from both ends. That is, when the pressing mechanism pushes downward on the steel strip 200 above the battery module 100, the two second side edges of the steel strip 200 slide downward onto the two first guide assemblies 8 and, supported and guided by the two first guide assemblies 8, transition to the battery module 100.

[0115] Optionally, the first guide assembly 8 includes a fifth driving member 81, a first guide block 82 and a second guide block 83, wherein: the fifth driving member 81 is arranged on the lifting bracket 4, the first guide block 82 and the second guide block 83 are relatively installed on the two driving ends of the fifth driving member 81 along the second horizontal direction, and the fifth driving member 81 is used to drive the first guide block 82 and the second guide block 83 to slide closer to the middle or slide apart to both sides to adjust the distance between the first guide block 82 and the second guide block 83.

[0116] When the lifting drive mechanism 3 drives the lifting bracket 4 to descend into place, the first guide block 82 and the second guide block 83 are tightly attached to the two side edges of the battery cell module 100. When the pressing mechanism pushes the steel strip 200 downward, the first guide block 82 and the second guide block 83 support and guide the two second side edges of the steel strip 200 from the inside, so that the steel strip 200 is put on the battery cell module 100.

[0117] The optional working process of the first guide assembly 8 is as follows:

[0118] In the initial state, the lifting bracket 4 is at an initial high position away from the battery module 100, and the first guide block 82 and the second guide block 83 move toward the middle, thereby avoiding the steel belt 200, so that the steel belt 200 can be received and tightened by the stretching component 7.

[0119] Then, the fifth driving member 81 drives the first guide block 82 and the second guide block 83 to slide apart to both sides, so that the distance between the first guide block 82 and the second guide block 83 is adapted to the width of the battery cell module 100, and the first guide block 82 and the second guide block 83 support the two second side edges of the steel strip 200 from the inside.

[0120] Subsequently, the lifting drive mechanism 3 drives the lifting bracket 4 down to its proper position, so that the first guide block 82 and the second guide block 83 are in close contact with the two side edges of the battery cell module 100. Thus, when the pressing mechanism pushes the steel strip 200 downward, the first guide block 82 and the second guide block 83 guide the two second side edges of the steel strip 200 from the inside, ultimately allowing the steel strip 200 to be fitted onto the battery cell module 100.

[0121] The fifth driving member 81 can, for example, be a clamping cylinder with two driving ends, with the first guide block 82 and the second guide block 83 mounted oppositely to each other on the two driving ends of the clamping cylinder. The clamping cylinder controls the two driving ends to clamp or open, thereby driving the first guide block 82 and the second guide block 83 to slide toward the center or to slide apart. Of course, the fifth driving member 81 can also be a two driving cylinders with opposite driving directions, with the driving ends of the two cylinders connected to the first guide block 82 and the second guide block 83, respectively, to achieve reverse driving of the first guide block 82 and the second guide block 83.

[0122] like Figure 9 As shown, the first and second guide blocks 82, 83 are each provided with a retaining groove on their inner sides, while their outer sides form guide surfaces extending vertically. When the lifting drive mechanism 3 lowers the lifting bracket 4 into position, the first and second guide blocks 82, 83 engage the two side edges of the battery cell module 100 via their inner retaining grooves. When the pressing mechanism pushes the steel strip 200 downward, the first and second guide blocks 82, 83 guide the two second side edges of the steel strip 200 downwardly via their outer guide surfaces.

[0123] like Figure 6 、 Figure 7 and Figure 10As shown, the battery module steel strip wrapping equipment in the embodiment of the present application optionally further includes a second guide mechanism disposed on the lifting bracket 4. When the pressing mechanism pushes the steel strip 200 downward, the second guide mechanism is configured to support and guide the two opposing first side edges of the steel strip 200 from the inside, allowing the steel strip 200 to slide downward to a preset position under the guidance of the second guide mechanism. The first side edge is, for example, a short side of the steel strip 200.

[0124] By setting up a second guide mechanism, when the pressing mechanism pushes the steel belt 200 downward, the second guide mechanism supports and guides the two opposite first side edges of the steel belt 20 from the inside, so that the steel belt 200 slides downward to a preset position under the guidance of the second guide mechanism, preventing the steel belt 200 from getting stuck or tilting during the sliding process.

[0125] Optionally, the second guide mechanism includes two second guide assemblies 9 provided at both ends of the lifting bracket 4 , and the two second guide assemblies 9 respectively support and guide the two first side edges of the steel belt 200 from the outside of both ends of the battery cell module 100 .

[0126] Optionally, the second guide assembly 9 includes a second lifting drive 91 and a guide plate 92. The second lifting drive 91 is disposed on the lifting bracket 4, and the guide plate 92 is connected to the driving end of the second lifting drive 91. The second lifting drive 91 is used to drive the guide plate 92 downward so that the guide plate 92 is in close contact with the longitudinal end surface of the battery cell module 100.

[0127] Before the pressing mechanism pushes the steel strip 200 downward, the second lifting drive member 91 drives the guide plate 92 downward. This causes the guide plate 92 to pass through the steel strip 200 and then descend, close to the end surface of the battery module 100, until the lower end of the guide plate 92 approaches the preset position. Thus, as the pressing mechanism pushes the steel strip 200 downward, the two first side edges of the steel strip 200 slide downward, guided by the guide plates 92 at the two end surfaces of the battery module 100, until they reach the preset position.

[0128] The second lifting drive member 91 can adopt various existing linear drive modules that can drive the guide plate 92 to move up and down, such as a cylinder, a screw motor, etc.

[0129] like Figure 9As shown, the battery cell module steel strip sheathing equipment in the embodiment of the present application optionally further includes a pressing plate 10 disposed at the bottom of the lifting bracket 4. When the lifting drive mechanism 3 drives the lifting bracket 4 down to its proper position, the pressing plate 10 presses against the upper surface of the battery cell module 100, thereby further ensuring that the battery cell module 100 remains fixed during the steel strip sheathing process. Optionally, a plurality of pressing plates 10 are provided, and the plurality of pressing plates 10 are spaced apart along the first horizontal direction at the bottom of the lifting bracket 4. The plurality of pressing plates 10 simultaneously press the battery cell module from different positions to enhance the downward pressing effect of the battery cell module.
