Description

Technical Field

[0001] This application relates to the field of semiconductor production equipment, and more specifically to an automatic steel belt sleeving device for battery cell modules. Background Art

[0002] As Figure 1 shown, the battery cell module 100 is formed by stacking multiple battery cells 101. In order to fasten the multiple battery cells 101, it is necessary to tightly sleeve the steel belt 200 outside the battery cell module 100 so that the multiple battery cells 101 are closely attached to each other. For a conventional battery cell module, generally two steel belts 200 need to be sleeved.

[0003] In the existing automatic steel belt sleeving device for battery cell modules, after the material frame storing the steel belt moves to the loading station, it is necessary to pick up the steel belt from the material frame manually or by a dedicated loading manipulator, then move and load the steel belt onto the steel belt sleeving device, and finally the steel belt sleeving device sleeves the steel belt onto the battery cell module. Both manual loading and loading by the loading manipulator require additional working beats, reducing the efficiency of steel belt sleeving. Utility Model Content

[0004] In order to solve the above technical problems, this application provides an automatic steel belt sleeving device for battery cell modules, which adopts the following technical solutions:

[0005] An automatic steel belt sleeving device for battery cell modules includes a steel belt feeding device, a battery cell module pressing device, and a steel belt sleeving device, wherein:

[0006] The battery cell module pressing device includes a carrying platform and two pressing mechanisms. Among them, the carrying platform is used to carry the battery cell module, and the two pressing mechanisms are respectively arranged at both ends in the length direction of the carrying platform, and the two pressing mechanisms are configured to press the battery cell module located on the carrying platform from both ends;

[0007] The steel belt feeding device is configured to carry the material frame stacked with steel belts, and is configured to pick up the steel belt from the material frame and then lift the steel belt to a predetermined feeding position;

[0008] The steel belt sleeving device is configured to pick up the steel belt from the feeding position, and after moving the picked-up steel belt above the pressed battery cell module, the steel belt sleeving device is further configured to sleeve the steel belt from top to bottom to a preset position of the battery cell module.

[0009] The automatic steel belt sleeving device for the battery cell module provided by this application can pick up the steel belt from the steel belt feeding device by itself and sleeve the picked-up steel belt at a preset position of the squeezed battery cell module, thereby improving the steel belt sleeving efficiency. In particular, since the steel belt feeding device always lifts the steel belt to be picked up to a predetermined feeding position each time, the steel belt sleeving device can pick up the steel belt from the feeding position each time, thus simplifying the moving stroke of the steel belt sleeving device and further improving the steel belt sleeving efficiency.

[0010] In some embodiments, the steel belt sleeving device includes a moving mechanism, a mounting bracket, a spreading mechanism and a pressing-in mechanism, wherein: both the spreading mechanism and the pressing-in mechanism are arranged on the mounting bracket; the moving mechanism is configured to drive the mounting bracket to move, so that the spreading mechanism penetrates into the steel belt at the feeding position from top to bottom, and the spreading mechanism is configured to spread the steel belt; the moving mechanism is further configured to drive the mounting bracket to move to move the spread steel belt above the squeezed battery cell module; the pressing-in mechanism is configured to push down the steel belt spread by the spreading mechanism to sleeve the steel belt outside the battery cell module and descend to a preset position.

[0011] Driven by the moving mechanism, the spreading mechanism receives and spreads the steel belt from the feeding position and transfers the spread steel belt above the battery cell module. Subsequently, the pressing-in mechanism pushes down the steel belt spread by the spreading mechanism, so that the steel belt slides down along the battery cell module after being sleeved outside the battery cell module until it reaches the preset position. It can be seen that through the cooperation of the spreading mechanism and the pressing-in mechanism and the drive of the moving mechanism, the steel belt sleeving device realizes the automatic picking up of the steel belt and automatically sleeving the steel belt at a preset position of the squeezed battery cell module.

[0012] In some embodiments, the steel belt feeding device includes a loading table and a picking part, wherein: the loading table is configured to carry a material frame stacked with steel belts; the picking part includes a lifting mechanism and a picking mechanism. The picking mechanism is connected to the movable part of the lifting mechanism and is located above the loading table. The lifting mechanism is configured to drive the picking mechanism to lift and lower, so as to drive the picking mechanism to pick up the topmost steel belt from the material frame and lift the picked-up steel belt to the feeding position; the spreading mechanism is configured to penetrate into the steel belt lifted to the feeding position by the picking mechanism from top to bottom and spread the steel belt.

[0013] After the picking part takes out the steel belt in the material frame on the loading table, it lifts the taken-out steel belt to the feeding position. In this way, the steel belt sleeving device can take away the steel belt from the same position each time, thus simplifying the moving stroke of the steel belt sleeving device and improving the production efficiency.

[0014] In some embodiments, the steel strip feeding device further includes a transfer unit configured to transfer two material frames stacked with steel strips onto the loading table and transfer the emptied material frames on the loading table out of the loading table; the lifting mechanism is configured to drive the material picking mechanism to lift, so as to drive the material picking mechanism to pick up the steel strips at the topmost layer from the two material frames simultaneously and lift the picked steel strips to the feeding position; the spreading mechanism is configured to penetrate into one of the two groups of steel strips lifted to the feeding position by the material picking mechanism from top to bottom and spread the group of steel strips.

[0015] Generally, two steel strips need to be sleeved on the battery cell module. The material picking mechanism simultaneously takes out two groups of steel strips from the two material frames and lifts the two groups of steel strips taken out simultaneously to the feeding position. The spreading mechanism can continuously pick up two steel strips from the feeding position, so that the steel strip sleeving device can continuously sleeve the two steel strips onto the battery cell module, thereby improving the efficiency of sleeving the steel strips on the battery cell module.

[0016] In some embodiments, the steel strip feeding device includes two groups of loading tables and a material picking unit, and the two groups of loading tables and the material picking unit are respectively located on both sides of the battery cell module pressing device; after the steel strips are emptied from the material frames on the first group of loading tables, the steel strip sleeving device picks up the steel strips from the material frames carried on the second group of loading tables, and the first group of loading tables receive and carry new material frames with steel strips.

[0017] Loading tables and a material picking unit are arranged on both sides of the battery cell module pressing device. The two groups of loading tables and the material picking unit can both perform the feeding of the steel strips, and the steel strip sleeving mechanism can pick up the steel strips from the feeding position on either side. When the steel strips in the material frames on one of the loading tables are emptied and the material frames need to be replaced, the steel strip sleeving mechanism can pick up the steel strips from the feeding position on the other side, thereby avoiding the waiting for feeding and ensuring the working rhythm.

[0018] In some embodiments, the pressing mechanism includes a base and at least two pressing components arranged at intervals in the vertical direction on the base. Each pressing component can independently extend or retract along the length direction of the carrying table to press or disengage from the battery cell module from the corresponding pressing position; during the process of pressing the steel strip downward, the pressing component is configured to disengage from the battery cell module when the steel strip passes through the corresponding pressing position to avoid the steel strip; after the steel strip passes over the corresponding pressing position, the pressing component resets to press the battery cell module again.

[0019] Since the pressing components of the pressing mechanism can move towards or away from the battery cell module, when the steel belt slides down the battery cell module from top to bottom, each pressing component can avoid the steel belt, so as to ensure that the steel belt can slide to the corresponding preset position. After the steel belt passes over the pressing positions of each pressing component, the pressing component immediately resumes pressing the battery cell module. In addition, since at least two pressing components are arranged at intervals in the vertical direction on the pressing mechanism, when one of the pressing components disengages from the battery cell module to avoid the steel belt, the other pressing components maintain pressing on the battery cell module, so as to ensure that the battery cell module is always in a pressed state during the steel belt sleeving process.

[0020] In some embodiments, the pressing component includes a first driving member, a pressing plate and two pressing rods, wherein: the first driving member is installed on the base, the pressing plate is slidably installed on the base along a first horizontal direction, and the two pressing rods are installed on the side of the pressing plate facing the bearing table, and the first horizontal direction is parallel to the length direction of the bearing table; the first driving member is configured to drive the pressing plate to approach or move away from the battery cell module on the bearing table along the first horizontal direction, so that the two pressing rods press or move away from the battery cell module on the bearing table; when the pressing-in mechanism pushes down the steel belt, the gap between the two pressing rods is for the pressing-in mechanism to pass through.

[0021] By setting the pressing parts of the pressing component as two pressing rods with a gap therebetween, on the one hand, the pressing component presses the ends of the battery cell module from two different positions, so that the force on the ends of the battery cell module is uniform, and prevents the battery cells in the battery cell module from being damaged due to excessive local force. On the other hand, the pressing component can avoid the pressing-in mechanism, so that the pressing-in mechanism can pass through the pressing component downward to push the steel belt to a preset position below the pressing component.

[0022] In some embodiments, the battery cell module pressing device further includes a transfer component, wherein: the transfer component is configured to drive the bearing table and the two pressing mechanisms to move synchronously along the first horizontal direction to the loading station away from the steel belt sleeving device and the steel belt feeding device, and the bearing table bears the battery cell module to be sleeved with the steel belt at the loading station; the transfer component is further configured to drive the bearing table bearing the battery cell module to be sleeved with the steel belt and the two pressing mechanisms to move synchronously along the first horizontal direction to the steel belt sleeving station close to the steel belt sleeving device and the steel belt feeding device, and the steel belt sleeving device is configured to sleeve the picked-up steel belt from top to bottom to the preset position of the battery cell module at the steel belt sleeving station.

[0023] By setting the transfer component, the translation switching between the loading station and the band sleeving station of the loading platform and the two pressing mechanisms is realized. When the loading platform and the two pressing mechanisms are switched to the loading station, they are far away from the steel band sleeving device and the steel band feeding device. At this time, the battery cell module to be sleeved with the steel band can be smoothly placed on the loading platform, avoiding collisions between the battery cell module and the steel band sleeving device and the steel band feeding device. When the loading platform and the two pressing mechanisms are switched to the band sleeving station, the loading platform and the two pressing mechanisms are located below the steel band sleeving device and close to the steel band feeding device. In this way, the steel band sleeving device can sleeve the picked-up steel band to the preset position of the battery cell module nearby.

[0024] In some embodiments, the spreading mechanism includes two spreading components arranged at both ends of the mounting bracket along the first horizontal direction, and the first horizontal direction is parallel to the length direction of the loading platform; when the moving mechanism drives the mounting bracket to move to the feeding position, the two spreading components penetrate into the steel band at the feeding position from top to bottom, and the two spreading components are configured to separate from each other along the first horizontal direction to spread the two first side edges of the steel band, and the first side edge is perpendicular to the length direction of the loading platform; after the steel band moves above the battery cell module to be pressed, the pressing mechanism pushes down the steel band spread by the two spreading components to sleeve the steel band outside the battery cell module and descend to the preset position; the spreading component includes a second driving member, a moving plate and two supporting rods, wherein: the second driving member is arranged on the mounting bracket, the moving plate is slidably connected to the mounting bracket and connected to the driving end of the second driving member, and the two supporting rods are arranged at intervals along the second horizontal direction at the end of the moving plate, and the second horizontal direction is perpendicular to the first horizontal direction; after the two supporting rods of the spreading component penetrate into the steel band at the feeding position, the second driving member is configured to drive the moving plate to slide along the first horizontal direction to drive the two supporting rods to spread a first side edge of the steel band from the inside of the steel band.

[0025] The two spreading components cooperate with each other to realize the reception of the steel band and the spreading of the two opposite first side edges of the steel band, so that when the pressing mechanism pushes down the steel band, the steel band can be smoothly sleeved down to the preset position of the battery cell module. By setting the spreading component, when the second driving member drives the two supporting rods to slide along the first horizontal direction, the two supporting rods are driven to abut against the first side edge of the steel band from the inside of the steel band.

[0026] In some embodiments, the pressing mechanism includes two pressing assemblies corresponding to the expansion assemblies at both ends of the mounting bracket along the first horizontal direction; after the steel strip moves to the top of the squeezed battery cell module, the two pressing assemblies are configured to respectively push down the first side of the steel strip expanded by the corresponding expansion assemblies; the pressing assembly includes a third driving member, a connecting plate, a fourth driving member and a pressing block, wherein: the third driving member is arranged on the mounting bracket, the connecting plate is connected to the driving end of the third driving member, the fourth driving member is arranged at the lower end of the connecting plate, the pressing block is installed on the driving end of the fourth driving member, and the pressing block is located between the two support rods of the corresponding expansion assembly; when the steel strip moves to the top of the squeezed battery cell module, the fourth driving member drives the pressing block to translate toward the steel strip, so that the pressing block moves to the top of the first side of the steel strip expanded by the corresponding expansion assembly; the third driving member is configured to drive the pressing block to descend, so as to drive the pressing block to push the first side of the steel strip downward.

[0027] After the two pressing components respectively support the two opposite first side edges of the steel belt, driven by the mounting bracket, the two first side edges of the steel belt are pressed down synchronously, so that the steel belt can slide downward steadily 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 edge of the battery module during the sliding process. By setting the pressing components, when the third driving member drives the connecting plate and the pressing block thereon to descend, the pressing block can push the first side edge of the steel belt downward during the descent process. Since the pressing block is installed on the fourth driving member, the fourth driving member can drive the pressing block to switch between the pushing position and the avoidance position. When the opening mechanism needs to receive and open the steel belt, the fourth driving member drives the pressing block to move to the avoidance position to avoid the steel belt. When the steel belt needs to be pushed downward, the fourth driving member drives the pressing block to move to the pushing position, ensuring that when the third driving member drives the connecting plate to descend, the pressing block can press on the first side edge of the steel belt.

[0028] In some embodiments, the steel strip sleeving device further includes a stockpiling mechanism disposed on the mounting bracket; after the expanding mechanism expands the first steel strip at the feeding position, the stockpiling mechanism is configured to cache the first steel strip; the expanding mechanism is configured to continue expanding the second steel strip at the feeding position, and the second steel strip is located below the first steel strip; the pressing mechanism is configured to push down the second steel strip expanded by the expanding mechanism to sleevethe second steel strip outside the battery cell module and descend to a corresponding second preset position; the pressing mechanism is further configured to continue pushing down the cached first steel strip to sleevethe first steel strip outside the battery cell module and descend to a first preset position, and the first preset position is located above the second preset position; the stockpiling mechanism includes two caching components disposed at both ends of the mounting bracket along a first horizontal direction, and the first horizontal direction is parallel to the length direction of the carrier table; after the expanding mechanism expands the first steel strip at the feeding position, the two caching components are configured to support two opposite first sides of the first steel strip, and the first sides are perpendicular to the length direction of the carrier table; when the pressing mechanism pushes down the first steel strip, the two caching components are configured to release the support for two opposite first sides of the first steel strip.

[0029] By providing the stockpiling mechanism, after the expanding mechanism expands the first steel strip at the feeding position, the stockpiling mechanism caches the first steel strip, so that the expanding mechanism can continue to receive and expand the second steel strip from the feeding position. Subsequently, the moving mechanism drives the mounting bracket to move, moving the first steel strip and the second steel strip above the battery cell module to be squeezed. The pressing mechanism first pushes down the second steel strip expanded by the expanding mechanism to sleevethe second steel strip at the second preset position of the battery cell module. The pressing mechanism then continues to push down the cached first steel strip to sleevethe first steel strip at the first preset position of the battery cell module.

[0030] Through the cooperation of the stockpiling mechanism, the expanding mechanism and the pressing mechanism, the steel strip sleeving device of the present application can receive two steel strips at the same time and sequentially sleeve the two steel strips onto the battery cell module, thereby improving the steel strip sleeving efficiency.

[0031] By setting the stockpiling mechanism to include two caching components, the two caching components cooperate to support two opposite first sides of the first steel strip from both sides, thereby realizing stable caching of the first steel strip, ensuring that the first steel strip is in a horizontal state, and facilitating the pressing mechanism to smoothly push down the first steel strip downward.

[0032] In some embodiments, the caching component includes a fifth driving member and a caching plate. The fifth driving member is disposed on the mounting bracket, and the caching plate is connected to the driving end of the fifth driving member; when the fifth driving member drives the caching plate to move towards the first steel strip, the caching plate extends below the first side of the first steel strip to support the first side of the first steel strip; when the fifth driving member drives the caching plate to move away from the first steel strip, the caching plate withdraws from below the first side of the first steel strip to release the support for the first side of the first steel strip.

[0033] A cache component with a simple structure is provided, which drives the cache plate to translate through a fifth driving member to implement caching and cache release of the steel strip. Description of the Drawings

[0066] To make the above objects, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the drawings and specific implementation manners.

[0067] As shown in Figure 2 and Figure 5As shown in the figure, the automatic steel strip sleeving device for the battery cell module in the embodiment of the present application includes a steel strip feeding device 10, a battery cell module pressing device 20, and a steel strip sleeving device 30, where:

[0068] The battery cell module pressing device 20 includes a carrier table 21 and two pressing mechanisms 22. Among them, the carrier table 21 is used to carry the battery cell module 100, and the two pressing mechanisms 22 are respectively arranged at both ends of the length direction of the carrier table 12 (such as Figure 5 the direction shown by the X-axis in the figure), and the two pressing mechanisms 22 are configured to press the battery cell module 100 located on the carrier table 21 from both ends.

[0069] The steel strip feeding device 10 is configured to carry the material frame 300 stacked with the steel strip 200, and is configured to pick up the steel strip 200 from the material frame 300 and then lift the steel strip 200 to a predetermined feeding position.

[0070] The steel strip sleeving device 30 is configured to pick up the steel strip 200 from the feeding position, and after moving the picked-up steel strip 200 above the pressed battery cell module 100, the steel strip sleeving device 30 is further configured to sleevethe steel strip 200 from top to bottom to a preset position of the battery cell module 100.

[0071] In the automatic steel strip sleeving device for the battery cell module in the embodiment of the present application, the steel strip sleeving device 30 can pick up the steel strip 200 from the material frame 300 on the steel strip feeding device 10 by itself, and sleevethe picked-up steel strip 200 to the preset position of the pressed battery cell module 100, thereby improving the steel strip sleeving efficiency.

[0072] In particular, since the steel strip feeding device 10 always lifts the steel strip 200 taken out from the material frame 300 to a predetermined feeding position, the steel strip sleeving device 30 can always pick up the steel strip from the feeding position each time, thereby simplifying the moving stroke of the steel strip sleeving device 30 and further improving the steel strip sleeving efficiency.

[0073] As Figures 8 to 12 shown, optionally, the steel strip sleeving device 30 includes a moving mechanism 31, a mounting bracket 32, a spreading mechanism 33, and a pressing-in mechanism 34, where: both the spreading mechanism 33 and the pressing-in mechanism 34 are arranged on the mounting bracket 32. The moving mechanism 31 is configured to drive the mounting bracket 32 to move, so that the spreading mechanism 33 penetrates into the steel strip 200 located at the feeding position from top to bottom, and the spreading mechanism 33 is configured to spread the steel strip 200. The moving mechanism 31 is further configured to drive the mounting bracket 32 to move to move the spread steel strip 200 above the pressed battery cell module 100. The pressing-in mechanism 34 is configured to push down the steel strip 200 spread by the spreading mechanism 33 to sleevethe steel strip 200 outside the battery cell module 100 and lower it to a preset position.

[0074] The optional steel belt sleeving process of the steel belt sleeving device 30 is as follows:

[0075] First, the moving mechanism 31 drives the mounting bracket 32 to move towards the feeding position until the expanding mechanism 33 penetrates into the steel belt 200 at the feeding position from top to bottom, and then the expanding mechanism 33 expands the steel belt 200.

[0076] Next, the moving mechanism 31 drives the mounting bracket 32 to move towards the compressed battery cell module 100 until the expanded steel belt 200 moves directly above the battery cell module 100 and is close to the battery cell module 100.

[0077] Subsequently, the pressing mechanism 34 pushes down the steel belt 200 expanded by the expanding mechanism 33, so that the steel belt 200 is sleeved outside the battery cell module 100 and slides down along the battery cell module 100 until it reaches the preset position.

[0078] It can be seen that through the cooperation of the expanding mechanism 33 and the pressing mechanism 34, and driven by the moving mechanism 31, the steel belt sleeving device 3 realizes the automatic picking up of the steel belt 200 and automatically sleeving the steel belt 200 to the preset position of the compressed battery cell module 100.

[0079] The moving mechanism 31 includes, for example, a translation drive module and a lifting drive module connected to the moving part of the translation drive module. Figure 8 and Figure 9 only show the lifting drive module of the moving mechanism 31. The translation drive module and the lifting drive module cooperate to drive the mounting bracket 32 to translate and lift, so as to drive the expanding mechanism 33 and the pressing mechanism 34 to move and switch between the feeding position and the compressed battery cell module 100.

[0080] As Figure 3 and Figure 4 shown, the steel belt feeding device 10 includes a feeding table 11 and a picking part 12, wherein: the feeding table 11 is configured to carry the material frame 300 stacked with the steel belts 200. The picking part 12 includes a lifting mechanism 121 and a picking mechanism 122. The picking mechanism 122 is connected to the moving part of the lifting mechanism 121 and is located above the feeding table 11. The lifting mechanism 121 is configured to drive the picking mechanism 122 to lift, so as to drive the picking mechanism 122 to pick up the topmost steel belt 200 from the material frame 300 and lift the picked steel belt 200 to the feeding position D. When the moving mechanism 31 drives the mounting bracket 32 to move towards the feeding position D, the expanding mechanism 33 penetrates into the steel belt 200 lifted to the feeding position D by the picking mechanism 122 from top to bottom under the drive of the mounting bracket 32 and expands the steel belt 200.

[0081] Since each time the material taking part 12 takes out the steel strip 200 in the material frame 300 on the loading table 11, it lifts the taken-out steel strip 200 to the feeding position D. In this way, the steel strip sleeving device 30 can take away the steel strip 200 from the same position (i.e., the feeding position D) each time, thus simplifying the moving stroke of the steel strip sleeving device 30 and improving the production efficiency.

[0082] Optionally, the material taking mechanism 122 includes a lifting cross beam 1221, a holding driving part, a first holding part 1222 and a second holding part 1223, wherein: the lifting cross beam 1221 is connected to the movable part of the lifting mechanism 121. The first holding part 1222 and the second holding part 1223 are slidably connected to the lifting cross beam 1221 and are in transmission connection with the holding driving part arranged on the lifting cross beam 1221. The lifting mechanism 121 is configured to drive the lifting cross beam 1221 to descend, so that the first holding part 1222 and the second holding part 1223 descend to the outside of the steel strip 200 to be picked up on the uppermost layer of the material frame 300. The holding driving part is configured to drive the first holding part 1222 and the second holding part 1223 to slide towards the middle and close together, so that the first holding part 1222 and the second holding part 1223 respectively hold two opposite sides of the steel strip 200 to be picked up.

[0083] After the first holding part 1222 and the second holding part 1223 hold two opposite sides of the steel strip 200 to be picked up, the lifting mechanism 121 drives the lifting cross beam 1221 to rise until the held steel strip 200 rises to the feeding position D.

[0084] The lifting mechanism 121 can adopt various existing linear driving modules that can drive the material taking mechanism 122 to lift, such as a synchronous belt driving module. Optionally, the structures of the first holding part 1222 and the second holding part 1223 are the same. Taking the first holding part 1222 as an example, it includes a holding arm and a holding block installed on the cross beam. Among them, the holding arm is connected to the lifting cross beam 1221 and is in transmission connection with the holding driving part. The holding arm is perpendicular to the lifting cross beam 1221, and the holding block is provided with a holding groove matching the height of the steel strip 200.

[0085] The holding driving part can adopt various existing driving parts that can drive the first holding part 1222 and the second holding part 1223 to slide towards the middle and close together and slide apart towards both sides along the lifting cross beam 1221.

[0086] Such as Figure 3As shown, optionally, the steel strip feeding device 10 further includes a transfer part 13 configured to transfer two material frames 300 stacked with steel strips 200 onto the loading table 11, and transfer the emptied material frames 300 on the loading table 11 out of the loading table 11. When the lifting mechanism 121 drives the material taking mechanism 122 to descend towards two material frames 300 stacked with steel strips 200, the material taking mechanism 122 can simultaneously pick up the steel strips 200 located on the top layer from the two material frames 300, and lift the two groups of picked steel strips 200 to the feeding position. The spreading mechanism 33 is configured to penetrate into one of the two groups of steel strips lifted to the feeding position by the material taking mechanism 122 from top to bottom and spread the group of steel strips 200.

[0087] The transfer part 13 is, for example, a trolley with conveying rollers. After the transfer part 13 is docked with the loading table 11 and pushes the material frame 300 towards the loading table 11, the material frame 300 can enter the loading table 11 under the guidance of the conveying rollers.

[0088] Generally, two steel strips 200 need to be sleeved on the battery cell module 100. The material taking mechanism 122 simultaneously takes out two groups of steel strips 200 from the two material frames 300. Each group of steel strips 200 includes two steel strips 200 spaced up and down, and lifts the two groups of simultaneously taken steel strips 200 to the feeding position D. In this way, the spreading mechanism 33 can continuously pick up the two steel strips spaced up and down in the first group from the feeding position, and finally enable the steel strip sleeving device 30 to continuously sleeve the two steel strips 200 onto the battery cell module 100, thereby improving the efficiency of sleeving the steel strips on the battery cell module 100. Subsequently, the spreading mechanism 33 returns to the feeding device D to pick up the second group of two steel strips spaced up and down for sleeving on the next battery cell module 100, reducing the working frequency of the material taking mechanism 122.

[0089] As Figure 2 As shown, optionally, the steel strip feeding device includes two groups of loading tables 11 and a material taking part 12, and the two groups of loading tables 11 and the material taking part 12 are respectively located on both sides of the battery cell module pressing device 20. After the steel strips 200 are emptied from the material frame 300 on the first group of loading tables 11, the steel strip sleeving device 30 picks up the steel strips 200 from the material frame 300 carried on the second group of loading tables 11, and the first group of loading tables 11 receives and carries a new material frame 300 with steel strips 200.

[0090] Since the loading tables 11 and the material taking parts 12 are arranged on both sides of the battery cell module pressing device 20, both groups of loading tables 11 and the material taking parts 12 can implement the feeding of the steel strips 200, and the steel strip sleeving device 30 can pick up the steel strips at the feeding position D on either side. When the steel strips 200 in the material frame 300 on one side of the loading table 11 are emptied and the material frame needs to be replaced. The steel strip sleeving device 30 can pick up the steel strips from the feeding position D on the other side, thereby avoiding feeding waiting and ensuring the working rhythm.

[0091] As shown Figures 6 to 7 in the figure, the pressing mechanism 22 includes a base 221 and at least two pressing components 222 arranged at intervals in the vertical direction on the base 221. Each pressing component 222 can independently extend or retract along the length direction of the carrier table 21 to press or disengage from the battery cell module 100 at the corresponding pressing position. During the process of the pressing mechanism 34 pressing the steel strip 200 downward, the pressing component 222 is configured to disengage from the battery cell module 100 when the steel strip 200 passes through the corresponding pressing position to avoid the steel strip. After the steel strip 200 passes over the corresponding pressing position, the pressing component 222 resets to press the battery cell module 100 again.

[0092] In the following, taking the example that two steel strips 200 need to be sleeved on the battery cell module 100 and the pressing mechanism 22 includes two pressing components 222, an exemplary description of the steel strip sleeving process of the battery cell module pressing device 20 and the steel strip sleeving device 30 will be given. It should be noted that since the structures and operation processes of the two pressing mechanisms 22 are the same, only the detailed operation process of one of the pressing mechanisms 22 will be described below when describing the steel strip sleeving process.

[0093] The steel strip sleeving process of the battery cell module pressing device 20 and the steel strip sleeving device 30 in the embodiment of the present application is as follows:

[0094] First, load the battery cell module 100 onto the carrier table 21, and control the two pressing mechanisms 22 to move towards the carrier table 21 so that the two pressing mechanisms 22 are respectively close to the end faces of the battery cell module 100 along the length direction.

[0095] Subsequently, control the two pressing components 222 of the pressing mechanism 22 to extend towards the battery cell module 100 so that the two pressing components 222 of the pressing mechanism 22 press the end faces of the battery cell module 100 from the corresponding pressing positions. Of course, the pressing position of the first pressing component 222 located above is higher than the pressing position of the second pressing component 222 located below.

[0096] When the first steel strip 200 to be installed moves above the battery cell module 100, the pressing mechanism 34 presses the first steel strip 200 downward so that the first steel strip 200 slides down along the side wall of the battery cell module 100 after being sleeved on the battery cell module 100 until it reaches the corresponding preset position. Among them, the preset position corresponding to the first steel strip 200 is below the pressing position of the second pressing component 222.

[0097] During the sliding process, the first steel belt 200 needs to sequentially pass over the pushing position of the first extrusion assembly 222 and the pushing position of the second extrusion assembly 222. Specifically, when the first steel belt 200 is about to reach the pushing position of the first extrusion assembly 222, the first extrusion assembly 222 retracts away from the battery cell module 100 to disengage from the battery cell module 100, thereby avoiding the first steel belt 200. After the first steel belt 200 passes over the pushing position of the first extrusion assembly 222, the first extrusion assembly 222 extends again to resume the extrusion of the battery cell module 100. Similarly, when the first steel belt 200 is about to reach the pushing position of the second extrusion assembly 222, the second extrusion assembly 222 retracts away from the battery cell module 100 to disengage from the battery cell module 100, thereby avoiding the first steel belt 200. The first steel belt 200 passes over the pushing position of the second extrusion assembly 22 and reaches the corresponding preset position. At this point, the installation of the first steel belt 200 is completed.

[0098] When the second steel strip 200 to be installed moves to the top of the battery module 100, the pressing mechanism 34 pushes the second steel strip 200 downward, so that after the second steel strip 200 is put on the battery module 100, it slides down along the side wall of the battery module 100 until it reaches the corresponding preset position. The preset position corresponding to the second steel strip 200 is located between the pushing position of the first pressing assembly 222 and the pushing position of the second pressing assembly 222.

[0099] During the downward movement, the second steel belt 200 needs to pass the pushing position of the first extrusion assembly 222. When the second steel belt 200 is about to reach the pushing position of the first extrusion assembly 222, the first extrusion assembly 222 retracts away from the battery module 100 to detach from the battery module 100, thereby avoiding the second steel belt 200. After the second steel belt 200 passes the pushing position of the first extrusion assembly 222, the first extrusion assembly 222 extends again to resume extrusion of the battery module 100. The second steel belt 200 reaches the corresponding preset position, and the installation of the second steel belt 200 is completed.

[0100] Subsequently, the two squeezing assemblies 222 of the squeezing mechanism 22 are controlled to retract away from the cell module 100 to release the cell module 100. The two squeezing mechanisms 22 are controlled to move away from the carrier 21 to return to their original positions, so as to facilitate the unloading device to unload the cell module 100 from the carrier 21.

[0101] It can be seen that since the extrusion components 222 of the extrusion mechanism 22 can move towards or away from the battery cell module 100, when the steel belt slides down the battery cell module 100 from top to bottom, each extrusion component 222 can avoid the steel belt 200, so as to ensure that the steel belt 200 can slide to the corresponding preset position. After the steel belt 200 passes over the pressing positions of the extrusion components 222, the extrusion components 222 immediately resume pressing the battery cell module 100. In addition, since at least two extrusion components 222 are arranged at intervals in the vertical direction on the extrusion mechanism 22, when one of the extrusion components 222 disengages from the battery cell module 100 to avoid the steel belt 200, the other extrusion components 222 keep pressing the battery cell module 100, so as to ensure that the battery cell module 100 is always in a pressed state during the steel belt sleeving process.

[0102] As Figure 6 shown, optionally, the extrusion component 222 includes a first driving member 2221, an extrusion plate 2222 and two extrusion rods 2223, wherein: the first driving member 2221 is installed on the base 221, the extrusion plate 2222 is slidably installed on the base 221 along a first horizontal direction, the two extrusion rods 2223 are installed on the side of the extrusion plate 2222 facing the bearing table 21, and the first horizontal direction is parallel to the length direction of the bearing table 21. The first driving member 2221 is configured to drive the extrusion plate 2222 to approach or move away from the battery cell module 100 on the bearing table 21 along the first horizontal direction, so that the two extrusion rods 2223 press or move away from the battery cell module 100 on the bearing table 21. When the pressing mechanism 34 presses the steel belt 200 downward, the gap between the two extrusion rods 2223 allows the pressing mechanism 34 to pass through.

[0103] By setting the extrusion parts of the extrusion component 222 as two extrusion rods 2223 with a gap therebetween, on the one hand, the extrusion component 222 presses the ends of the battery cell module 100 from two different positions, so that the stress on the ends of the battery cell module 100 is uniform, and the battery cells in the battery cell module 100 are prevented from being damaged due to excessive local stress. On the other hand, the extrusion component 222 can avoid the pressing mechanism 34, so that the pressing mechanism 34 can pass downward through the extrusion component 222 to push the steel belt 200 to a preset position below the extrusion component 222.

[0104] The first driving member 2221 can adopt various existing linear driving modules that can drive the extrusion plate 2222 to approach or move away from the bearing table 21 along the first horizontal direction, such as cylinders, lead screw motors, etc.

[0105] Optionally, the pressing mechanism 22 further includes a base 223 and a pressing assembly 224. The base 221 is slidably mounted on the base 223 in the first horizontal direction. The pressing assembly 224 includes a pressing plate 2242 and a pressing spring 2241. The pressing plate 2242 is mounted at the bottom end of the base 221 and extends in the first horizontal direction. The first end of the pressing spring 2241 is connected to the base 223, and the second end of the pressing spring 2241 is connected to the base 221. The pressing end of the pressing plate 2242 on the base 221 is continuously pressed against the end of the battery cell module 100 on the bearing table 21 under the pressure of the pressing spring 2241.

[0106] By slidably mounting the base 221 on the base 223 and providing the pressing assembly 224. When it is necessary to press the battery cell module 100 on the bearing table 21, first control the base 223 to move to a target position close to the battery cell module 100, so that the pressing end of the pressing plate 2242 on the base 221 is continuously pressed against the end of the battery cell module 100 under the pressure of the pressing spring 2241, so as to implement the fixed positioning of the end of the battery cell module 100.

[0107] On the one hand, the pressing assembly 224 pre-positions the battery cell module 100, thus facilitating the pressing assembly 222 to press the battery cell module 100. In addition, the pressing assembly 224 is continuously pressed against the end of the battery cell module 100 during the process of sleeving the steel strip, that is, the pressing assembly 224 can cooperate with the pressing assembly 222 to press the battery cell module 100, thereby increasing the pressing force of the pressing mechanism 22 on the battery cell module 100.

[0108] In addition, when the pressing assembly 224 presses against the end of the battery cell module 100, the pressing assembly 222 has already approached the battery cell module 100. Therefore, the pressing assembly 222 only needs to move a small stroke towards the battery cell module 100 to implement the pressing of the end of the battery cell module 100.

[0109] Of course, in order to prevent the pressing assembly 224 from blocking the downward sliding of the steel strip, the pressing assembly 224 is located below the preset position of the steel strip.

[0110] Optionally, the bases 223 of the two pressing mechanisms 22 are respectively slidably mounted at both ends of the bearing table 21 in the first horizontal direction. Correspondingly, as Figure 5 shown, the automatic steel strip sleeving device for the battery cell module in the embodiment of the present application further includes two translation driving mechanisms 24 corresponding to the two pressing mechanisms 22 one by one. The driving ends of the two translation driving mechanisms 24 are respectively fixedly connected to the bases 223 of the two pressing mechanisms 22.

[0111] The two translation driving mechanisms 24 are configured to synchronously drive the two pressing mechanisms 22 to slide towards the bearing table 21 and close together, so that the two pressing mechanisms 22 approach the battery cell module 100 located on the bearing table 12.

[0112] As shown Figure 2 in the figure, the cell module extrusion device 20 further includes a transfer assembly 23, where: the transfer assembly 23 is configured to drive the carrier table 21 and the two extrusion mechanisms 22 to synchronously move along the first horizontal direction to a loading station away from the steel belt sleeving device 30 and the steel belt feeding device 10, and the carrier table 21 carries the cell module 100 to be sleeved with a steel belt at the loading station. The transfer assembly 23 is further configured to drive the carrier table 21 carrying the cell module 100 to be sleeved with a steel belt and the two extrusion mechanisms 22 to synchronously move along the first horizontal direction to a steel belt sleeving station close to the steel belt sleeving device 30 and the steel belt feeding device 10, and the steel belt sleeving device 30 is configured to sleeved the picked steel belt 200 from top to bottom to a preset position of the cell module at the steel belt sleeving station.

[0113] By providing the transfer assembly 23, the translation switching between the loading station and the steel belt sleeving station of the carrier table 21 and the two extrusion mechanisms 22 is realized. When the carrier table 21 and the two extrusion mechanisms 22 are switched to the loading station, they are away from the steel belt sleeving device 30 and the steel belt feeding device 10. At this time, the cell module 100 to be sleeved with a steel belt can be smoothly placed on the carrier table 21, avoiding collisions between the cell module 100 and the steel belt sleeving device 30 and the steel belt feeding device 10. When the carrier table 21 and the two extrusion mechanisms 22 are switched to the steel belt sleeving station, the carrier table 21 and the two extrusion mechanisms 22 are located below the steel belt sleeving device 30 and close to the steel belt feeding device 10. In this way, the steel belt sleeving device 30 can sleeve the picked steel belt 200 to the preset position of the cell module 100 nearby.

[0114] The transfer assembly 23 can adopt a moving platform driven by a linear drive module, and the carrier table 21 and the two extrusion mechanisms 22 are both arranged on the moving platform. The linear drive module drives the moving platform to translate along the first horizontal direction, thereby driving the carrier table 21 and the two extrusion mechanisms 22 to translate and switch between the loading station and the steel belt sleeving station.

[0115] As shown Figure 9 in the figure, optionally, the spreading mechanism 33 includes two spreading components arranged at both ends of the mounting bracket 32 along the first horizontal direction, and the first horizontal direction is parallel to the length direction of the carrier table (such as Figure 9 the X-axis direction in). When the moving mechanism 31 drives the mounting bracket 32 to move to the feeding position, the two spreading components penetrate into the steel belt 200 located at the feeding position from top to bottom, and the two spreading components are configured to separate from each other along the first horizontal direction to spread the two first side edges of the steel belt 200, and the first side edge is the side edge of the steel belt 200 perpendicular to the length direction of the carrier table 12. The first side edge of the steel belt is generally the short side of the steel belt 200.

[0116] After the steel belt 200 is moved above the squeezed battery cell module 100, the pressing mechanism 34 pushes the steel belt 200, which is held open by two opening components, downward, so that the steel belt 200 is sleeved outside the battery cell module 100 and descends to a preset position.

[0117] The two opening components cooperate to open two opposite first side edges of the steel belt 200, which can ensure that when the pressing mechanism 34 pushes the steel belt 200 downward, the steel belt 200 can smoothly descend to the preset position of the battery cell module 100 in a horizontal posture.

[0118] As Figure 10 shown, optionally, the opening component includes a second driving member 331, a moving plate 332 and two support rods 333, where: the second driving member 331 is arranged on the mounting bracket 32, the moving plate 332 is slidably connected to the mounting bracket 32 and connected to the driving end of the second driving member 331, and the two support rods 333 are arranged at intervals at the end of the moving plate 332 along the second horizontal direction (such as the Y-axis direction in Figure 10 ), and the second horizontal direction is perpendicular to the first horizontal direction. After the two support rods 333 of the opening component penetrate into the steel belt 200 at the feeding position, the second driving member 331 is configured to drive the moving plate 332 to slide along the first horizontal direction, so as to drive the two support rods 333 to open a first side edge of the steel belt 200 from the inside of the steel belt 200.

[0119] The optional tightening process of the opening component for the first side edge of the steel belt 200 is as follows:

[0120] In the initial state, the two support rods 333 of the opening component are in the retracted position close to the mounting bracket 32, and the distance between the two support rods 333 of the opening component at the first end of the mounting bracket 32 and the two support rods 333 of the opening component at the second end of the mounting bracket 32 is less than the length of the second side edge (generally the long side of the steel belt) of the steel belt 200, so that the support rods 333 of the two opening components can all extend into the steel belt 200 to receive the steel belt 200.

[0121] Subsequently, the second driving member 331 drives the two support rods 333 of the opening component at the first end of the mounting bracket 32 to extend away from the mounting bracket 32 to the first side of the mounting bracket 32, and at the same time, the second driving member 331 drives the two support rods 333 of the opening component at the second end of the mounting bracket 32 to extend away from the mounting bracket 32 to the second side of the mounting bracket 32. In this way, two opposite first side edges of the steel belt 200 are respectively tightened by the two support rods 73.

[0122] Optionally, the distance between the two struts 333 of the spreading assembly is equivalent to the length of the first side of the steel strip 200. In this way, when the second driving member 331 drives the moving plate 332 to slide along the first horizontal direction, the two struts 333 can respectively press against the two corners of the steel strip 200 from the inside.

[0123] Through the cooperation of the four struts 333 of the two spreading assemblies, the four corners of the steel strip 200 are each pressed by a strut 333, and finally the four sides of the steel strip 200 are all tightened.

[0124] The second driving member 331 can adopt various existing linear driving modules that can drive the moving plate 332 to slide along the first horizontal direction, such as air cylinders, lead screw motors, etc.

[0125] As Figure 9 shown, optionally, the pressing mechanism 34 includes two pressing assemblies arranged at both ends of the mounting bracket 32 along the first horizontal direction and corresponding to the spreading assemblies one by one. After the steel strip 200 moves above the compressed battery cell module 100, the two pressing assemblies are configured to respectively push down the first side of the steel strip 200 spread by the corresponding spreading assembly.

[0126] After the steel strip 200 moves above the compressed battery cell module 100, the two pressing assemblies synchronously press down the two opposite first sides of the steel strip 200. In this way, it can be ensured that the steel strip 200 slides downward smoothly in a horizontal state until it reaches the preset position, preventing the steel strip 200 from tilting during the sliding process and preventing the steel strip 200 from jamming with the side wall of the battery cell module during the sliding process.

[0127] As Figure 11 and Figure 12 shown, optionally, the pressing assembly includes a third driving member 341, a connecting plate 342, a fourth driving member 343 and a pressing block 344, where: the third driving member 341 is arranged on the mounting bracket 32, the connecting plate 342 is connected to the driving end of the third driving member 341, the fourth driving member 343 is arranged at the lower end of the connecting plate 342, the pressing block 344 is installed on the driving end of the fourth driving member 343, and the pressing block 344 is located between the two struts 333 of the corresponding spreading assembly. When the steel strip 200 moves above the compressed battery cell module 100, the fourth driving member 343 drives the pressing block 344 to translate towards the steel strip 22 so that the pressing block 344 moves above the first side of the steel strip 200 spread by the corresponding spreading assembly. The third driving member 341 is configured to drive the pressing block 344 to descend to drive the pressing block 344 to push down the first side of the steel strip 200.

[0128] The third driving member 341 drives the connecting plate 342 and the pressing block 344 thereon to descend, so that the pressing block 344 can downwardly press the first side edge of the steel strip 200 during the descending process. In addition, since the pressing block 344 is installed on the driving end of the fourth driving member 343, the fourth driving member 343 can drive the pressing block 344 to switch between a pressing position and an avoidance position. When the spreading mechanism 33 needs to receive and spread the steel strip 200, the fourth driving member 343 drives the pressing block 344 to move to the avoidance position to avoid the steel strip 200, so that the steel strip 200 can be smoothly spread by the spreading mechanism 33. When it is necessary to downwardly press the steel strip 200, the fourth driving member 343 drives the pressing block 344 to move to the pressing position, so that the pressing block 344 extends above the first side edge of the steel strip 200, so as to ensure that when the third driving member 341 drives the connecting plate 342 to descend, the pressing block 344 can press on the first side edge of the steel strip 200 and press down the first side edge.

[0129] As Figure 12 shown, during the process that the pressing block 344 downwardly presses the steel strip 200, the connecting plate 342, the fourth driving member 343 and the pressing block 344 pass through the gap between the two pressing rods 2223 of the pressing assembly 222.

[0130] Both the third driving member 341 and the fourth driving member 343 can adopt various existing linear driving modules, such as air cylinders.

[0131] As Figure 11 shown, optionally, the pressing assembly further includes a supporting member 345 provided on the driving end of the fourth driving member 343. The supporting member 345 is located below the pressing block 344. The vertical distance between the supporting member 345 and the pressing block 344 is greater than the height of the steel strip 200. The supporting member 345 and the pressing block 344 cooperate to limit the moving amount of the steel strip 200 in the vertical direction.

[0132] By providing the supporting member 345 located below the pressing block 344, when the pressing block 344 downwardly presses the steel strip 200, the supporting member 345 can support and limit the steel strip 200, so as to prevent the steel strip 200 from separating from the pressing block 344 and deviating from the preset position.

[0133] As Figures 13 to 15 shown, in another embodiment, the steel strip sleeving device 30 further includes a stockpiling mechanism 35 provided on the mounting bracket 32. After the spreading mechanism 33 spreads the first steel strip 201 at the feeding position, the stockpiling mechanism 35 is configured to cache the first steel strip 201. The spreading mechanism 33 is configured to continue spreading the second steel strip 202 at the feeding position. The second steel strip 202 is located below the first steel strip 201.

[0134] The pressing mechanism 34 is configured to push down the second steel belt 202 expanded by the expanding mechanism 33, so as to sleave the second steel belt 202 outside the battery cell module 100 and descend to the corresponding second preset position. The pressing mechanism 34 is further configured to continue to push down the cached first steel belt 201, so as to sleave the first steel belt 201 outside the battery cell module 100 and descend to the first preset position, and the first preset position is above the second preset position.

[0135] Through the cooperation of the material storage mechanism 35, the expanding mechanism 33 and the pressing mechanism 34, the steel belt sleaving device 30 can receive two steel belts at the feeding position at the same time, and sleave the two steel belts on the battery cell module 100 in sequence, thereby improving the steel belt sleaving efficiency.

[0136] Optionally, the material storage mechanism 35 includes two buffer components arranged at both ends of the mounting bracket along the first horizontal direction. After the expanding mechanism 33 expands the first steel belt 201 at the feeding position, the two buffer components are configured to support two opposite first sides of the first steel belt 201. When the pressing mechanism 34 pushes down the first steel belt 201, the two buffer components are configured to release the support for two opposite first sides of the first steel belt 201. The first side of the steel belt is generally the short side of the steel belt.

[0137] The two buffer components cooperate from both sides to support two opposite first sides of the first steel belt 201, realizing stable buffering of the first steel belt 201, keeping the first steel belt 201 horizontal, and ensuring that the pressing mechanism 34 can smoothly push down the first steel belt 201.

[0138] As Figure 15 shown, optionally, the buffer component includes a fifth driving member 351 and a buffer plate 352. The fifth driving member 351 is arranged on the mounting bracket, and the buffer plate 352 is connected to the driving end of the fifth driving member 351. When the fifth driving member 351 drives the buffer plate 352 to move towards the first steel belt 201, the buffer plate 352 extends below the first side of the first steel belt 201 to support the first side of the first steel belt 201. When the fifth driving member 351 drives the buffer plate 352 to move away from the first steel belt 201, the buffer plate 352 withdraws from below the first side of the first steel belt 201 to release the support for the first side of the first steel belt 201.

[0139] The fifth driving member 351 can adopt various existing linear driving modules capable of driving the buffer plate 352 to move along the first horizontal direction, such as air cylinders, lead screw motors, etc.

[0140] The expanding mechanism 33 and the material storage mechanism 35 cooperate with each other, and the optional process of receiving and buffering the first steel belt 201 and the second steel belt 202 is as follows:

[0141] In the initial state, the buffer plates 352 of the two buffer components are at the initial positions close to the corresponding fifth driving members 351.

[0142] The moving mechanism 31 drives the mounting bracket 32 to descend towards the feeding position until the buffer plates 352 of the two buffer components descend below the two first sides of the first steel belt 201. Subsequently, the fifth driving members 351 of the two buffer components drive the corresponding buffer plates 352 to extend towards one first side of the first steel belt 201, so that the buffer plates 352 of the two buffer components respectively support one first side of the first steel belt 201.

[0143] The moving mechanism 31 drives the mounting bracket 32 to descend towards the feeding position again, so that the expanding mechanism 33 enters the second steel belt 202 and expands the second steel belt 202.

[0144] The expanding mechanism 33, the material storage mechanism 35 and the pressing mechanism 34 cooperate with each other to successively sleeved the second steel belt 202 and the first steel belt 201 onto the battery cell module 100. The specific process is as follows:

[0145] The moving mechanism 31 drives the mounting bracket 32 to move above the battery cell module 100, so that the pressing mechanism 34 and the second steel belt 202 approach the battery cell module 100.

[0146] Subsequently, the pressing mechanism 34 pushes down the second steel belt 202, so that after the second steel belt 202 is sleeved onto the battery cell module 100, it slides down along the side wall of the battery cell module 100 until it reaches the corresponding second preset position.

[0147] Then, the pressing mechanism 34 holds the first steel belt 201 buffered on the two buffer components. At the same time, the fifth driving members 351 of the two buffer components drive the corresponding buffer plates 352 to retract towards the fifth driving members 351, so that the buffer plates 352 are withdrawn from below the first side of the corresponding first steel belt 201.

[0148] Subsequently, the pressing mechanism 34 pushes down the first steel belt 201, so that after the first steel belt 201 is sleeved onto the battery cell module 100, it slides down along the side wall of the battery cell module 100 until it reaches the corresponding first preset position.

[0149] As Figure 15 shown, in order to ensure that the first side of the first steel belt 201 can be stably supported on the buffer plate 352, optionally, the buffer component includes two buffer plates 352, and the two buffer plates 352 are arranged side by side along the second horizontal direction (such as the Y-axis direction in Figure 15 ), and the second horizontal direction is perpendicular to the first horizontal direction. The two buffer plates 352 support one first side of the first steel belt 201 from two different positions.

[0150] AsFigure 15 As shown, in order to avoid the expansion assembly at the corresponding position, optionally, the two buffer plates 352 of the buffer assembly are located between the two support rods 333 of the expansion assembly.
