Description

Technical Field

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

[0002] A battery cell module is formed by stacking multiple battery cells, and end plates are respectively arranged at both ends of the battery cell module. In order to fasten multiple battery cells and the end plates at both ends, generally, two steel belts are sleeved on the outside of the battery cell module from top to bottom, so that multiple battery cells are closely attached to each other.

[0003] For battery cell modules of different models, the shapes of the end plates at both ends are also different. For example, Figure 1 for the battery cell module 100 shown, a fixing member extending along the length direction of the battery cell module 100 is arranged at the lower end of the end plate 300. Since the steel belt itself does not have obvious stretchability, it is necessary to first squeeze and contract the battery cell module from both ends of the battery cell module 100 through a squeezing mechanism, so that the steel belt 200 can be sleeved on the battery cell module. However, the deformation amount of the battery cell module when being squeezed is very small. For Figure 1 the end plate 300 in, both steel belts 200 can only be sleeved on the battery cell module 100 from top to bottom.

[0004] In order to improve production efficiency, generally, a pressing mechanism is now used to automatically sleeve the steel belt on the battery cell module. However, each time the pressing mechanism can only sleeve one steel belt on the battery cell module, and then go to pick up the second steel belt and sleeve the second steel belt on the battery cell module, which has the problem of cumbersome operation. Summary of the Utility Model

[0005] In order to solve the above technical problems, this application provides a squeezing mechanism for battery cell modules, and the following technical solutions are adopted:

[0006] An equipment for sleeving steel belts on battery cell modules includes a carrying platform, a lifting driving mechanism, a lifting bracket, a material storage mechanism, a pressing mechanism and two squeezing mechanisms, wherein:

[0007] The carrying platform is used for carrying the battery cell module. 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 both ends of the length direction of the battery cell module located on the carrying platform from both ends;

[0008] The lifting bracket is arranged above the carrying platform. The lifting bracket is connected to the driving end of the lifting driving mechanism. The material storage mechanism and the pressing mechanism are both arranged on the lifting bracket. The material storage mechanism caches the first steel belt and the second steel belt at intervals from bottom to top;

[0009] The lifting drive mechanism is configured to drive the lifting bracket to descend towards the battery cell module, so that the pressing mechanism approaches the battery cell module. The pressing mechanism is configured to push down the first steel belt cached by the material storage mechanism, so that after the first steel belt is sleeved on the battery cell module, it slides down along the side wall of the battery cell module to the first installation position;

[0010] The pressing mechanism is further configured to push down the second steel belt, so that after the second steel belt is sleeved on the battery cell module, it slides down along the side wall of the battery cell module to the second installation position, and the second installation position is above the first installation position.

[0011] Through the cooperation of the material storage mechanism and the pressing mechanism, the battery cell module steel belt sleeving device provided by the present application can place two steel belts on the pressing mechanism and the material storage mechanism respectively by manual or automated means. The pressing mechanism first pushes down the first steel belt it receives to the first installation position outside the battery cell module, and then the pressing mechanism takes the second steel belt from the material storage mechanism and pushes the second steel belt down to the second installation position, realizing the separate installation of the first steel belt and the second steel belt on the battery cell module. In this process, it is not necessary to send the steel belts manually or automatically in two times, improving the efficiency of sleeving the steel belts on the battery cell module.

[0012] In some embodiments, the material storage mechanism includes two buffer components arranged at both ends of the lifting bracket. The two buffer components are used to support two opposite first sides of the second steel belt, and the first side is perpendicular to the first horizontal direction.

[0013] The two buffer components cooperate to support two opposite first sides of the second steel belt from both sides, realizing the stable buffering of the second steel belt and preventing the second steel belt from tilting.

[0014] In some embodiments, the buffer component includes a first driving member and a buffer plate. The first driving member is arranged on the lifting bracket, and the buffer plate is connected to the driving end of the first driving member; when the first driving member drives the buffer plate to move towards the second steel belt, the buffer plate extends below the first side of the second steel belt to support the first side of the second steel belt; when the first driving member drives the buffer plate to move away from the second steel belt, the buffer plate withdraws from below the first side of the second steel belt.

[0015] A buffer component with a simple structure is provided, which drives the buffer plate to translate through the first driving member to implement the buffering of the corresponding first side of the second steel belt.

[0016] In some embodiments, the material storage mechanism further includes two spreading components arranged at both ends of the lifting bracket. The two spreading components are configured to move away from each other along the first horizontal direction to simultaneously spread two opposite first sides of the first steel belt and / or the second steel belt, and the first side is perpendicular to the first horizontal direction.

[0017] The two expansion components realize the tightening of the first steel strip and / or the second steel strip, so that when the pressing mechanism pushes the first steel strip or the second steel strip downward, the first steel strip or the second steel strip can be more smoothly put down onto the battery cell module.

[0018] In some embodiments, the support assembly includes a second driving member, a movable plate and two support rods, wherein: the second driving member is arranged on a lifting bracket, the movable plate is slidably connected to the lifting bracket and is connected to the driving end of the second driving member, the two support rods are arranged at intervals along the second horizontal direction at the end of the movable plate, the support rods extend along the vertical direction, and the second horizontal direction is perpendicular to the first horizontal direction; the second driving member is used to drive the movable plate to slide along the first horizontal direction, so as to drive the two support rods to support the first side of the first steel belt and / or the second steel belt from the inner side of the first steel belt and / or the second steel belt.

[0019] A simple-structured spreading assembly is provided, which drives two spreader rods to slide along a first horizontal direction through a second driving member, so as to drive the two spreader rods to spread the first side edge of the first steel belt and / or the second steel belt from two different positions on the inner side of the first steel belt and / or the second steel belt, thereby ensuring the spreading effect.

[0020] In some embodiments, the extrusion mechanism includes a base and at least two extrusion assemblies arranged on the base at intervals in the vertical direction, each extrusion assembly can independently extend or retract in a first horizontal direction to squeeze or disengage the battery cell module from a corresponding pushing position, and the extrusion assembly includes a third driving member, an extrusion plate and two extrusion rods, wherein: the third driving member is installed on the base, the extrusion plate is slidably installed on the base along the first horizontal direction, and the two extrusion rods are installed on the side of the extrusion plate facing the supporting platform; the third driving member is configured to drive the extrusion plate to approach or move 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.

[0021] Since the extrusion components of the extrusion mechanism can move toward or away from the battery module, when the first steel belt or the second steel belt slides from top to bottom along the battery module, each extrusion component can avoid the first steel belt or the second steel belt, thereby ensuring that the first steel belt or the second steel belt can slide to the corresponding installation position, and when the steel belt passes the pushing position of each extrusion component, the extrusion component immediately resumes extruding the battery module. In addition, since at least two extrusion components are arranged at intervals along the vertical direction on the extrusion mechanism, when one of the extrusion components is separated from the battery module to avoid the first steel belt or the second steel belt, the other extrusion components continue to squeeze the battery module, thereby ensuring that the battery module is always in an extruded state during the installation process of the first steel belt or the second steel belt.

[0022] By setting the extrusion members of the extrusion assembly as two extrusion rods with a gap therebetween, on the one hand, the extrusion assembly exerts extrusion on the end of the battery cell module from two different positions, so that the force on the end of the battery cell module is uniform, preventing the battery cells in the battery cell module from being damaged due to excessive local force. On the other hand, the extrusion assembly can avoid the pressing-in mechanism, enabling the pressing-in mechanism to pass downward through the extrusion assembly to push the first steel strip or the second steel strip to the installation position below the extrusion assembly.

[0023] In some embodiments, the extrusion assembly further includes a pushing block, a pushing wheel and a return spring, wherein: the pushing wheel is installed 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 connected to the driving end of the third driving member, a pushing inclined surface is formed on the pushing block, and the pushing wheel on the extrusion plate presses against the pushing inclined surface. The third driving member is configured to drive the pushing block to reciprocate slidably along the second horizontal direction, so that the pushing block switches between a pushing position and a release position, and the second horizontal direction is perpendicular to the first horizontal direction; when the third driving member drives the pushing block to slide from the release position towards the pushing position, the pushing inclined surface of the pushing block pushes the extrusion plate to slide along the first horizontal direction towards the battery cell module through the pushing wheel, so as to drive the extrusion end of the extrusion plate to extrude the end of the battery cell module, and the return spring elongates under the pulling of the extrusion plate; when the third driving member drives the pushing block to slide from the pushing position towards the release position, the pushing inclined surface of the pushing block gradually disengages from the pushing wheel, and the return spring retracts under the loss of pressure, so as to drive the extrusion plate to move away from the battery cell module along the first horizontal direction.

[0024] By setting the pushing block, the pushing wheel and the return spring, the third driving member pushes the pushing block perpendicular to the length direction of the battery cell module, and the pushing block pushes the pushing wheel on the extrusion plate through the pushing inclined surface thereon, thereby pushing the extrusion plate to extrude the battery cell module parallel to the length direction of the battery cell module. Compared with the existing extrusion method of directly driving the extrusion plate to extrude the battery cell module parallel to the length direction of the battery cell module, the third 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 third driving member is reduced, thereby reducing the risk of damage to the third driving member and prolonging the service life of the extrusion mechanism.

[0025] In some embodiments, the extrusion mechanism further includes a base and a pressing assembly. The base is slidably mounted on the base along the first horizontal direction. The pressing assembly includes a pressing plate and a pressing spring. The pressing plate is mounted at the bottom end of the base and extends along the first horizontal direction. The first end of the pressing spring is connected to the base, and the second end of the pressing spring is connected to the base. The pressing end of the pressing plate on the base is continuously pressed against the end of the battery cell module on the carrier under the pressure of the pressing spring. The bases of the two extrusion mechanisms are respectively slidably mounted at both ends of the carrier along the first horizontal direction. The battery cell module sleeving steel strip device further includes two translation driving mechanisms corresponding to the two extrusion mechanisms one by one. The driving ends of the two translation driving mechanisms are respectively fixedly connected to the bases of the two extrusion mechanisms. The two translation driving mechanisms are configured to synchronously drive the two extrusion mechanisms to slide closer to the carrier, so that the two extrusion mechanisms approach the battery cell module located on the carrier.

[0026] By slidably mounting the base on the base and arranging the pressing assembly. When it is necessary to extrude the battery cell module, first control the base to move to the target position close to the battery cell module, so that the pressing end of the pressing plate on the base can be continuously pressed against the end of the battery cell module under the pressure of the pressing spring, so as to implement the pre-positioning of the end of the battery cell module, thus facilitating the extrusion assembly to extrude the battery cell module. In addition, the pressing assembly is continuously pressed against the end of the battery cell module during the steel strip sleeving process, that is, the pressing assembly can cooperate to extrude 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 pressing assembly presses against the end of the battery cell module, the extrusion assembly has already approached the battery cell module. Therefore, the extrusion assembly only needs to move a small stroke towards the battery cell module to extrude the battery cell module.

[0027] By providing translation driving mechanisms corresponding to the two extrusion mechanisms one by one, the automatic driving of the two extrusion mechanisms is realized, so that the two extrusion mechanisms approach or move away from the battery cell module located on the carrier.

[0028] In some embodiments, the pressing-in mechanism includes two pressing-in components arranged at both ends in the length direction of the lifting bracket. The two pressing-in components are configured to respectively push two opposite first side edges of the first steel strip or the second steel strip, and the first side edge is perpendicular to the first horizontal direction.

[0029] Driven by the lifting bracket, the two pressing-in components simultaneously press down the two first side edges of the first steel strip or the second steel strip. In this way, it can be ensured that the first steel strip or the second steel strip slides down smoothly in a horizontal state until it reaches the corresponding installation position, preventing the first steel strip or the second steel strip from tilting during the sliding process, and preventing the first steel strip or the second steel strip from getting stuck with the side edge of the battery cell module during the sliding process.

[0030] In some embodiments, the pressing-in component includes a fourth driving member, a connecting plate, a fifth driving member, and a pressing block, wherein: the fourth driving member is arranged on the lifting bracket, the connecting plate is connected to the driving end of the fourth driving member, the pressing block is arranged on the connecting plate, and the gap between the two extrusion rods allows the connecting plate and the pressing block to pass through vertically; when the lifting driving mechanism drives the lifting bracket to descend in place, the fourth driving member is configured to drive the connecting plate to descend, so as to drive the pressing block to push down the first side edge of the first steel strip or the second steel strip; the fifth driving member is arranged at the bottom of the connecting plate, the pressing block is installed on the driving end of the fifth driving member, and the fifth driving member is configured to drive the pressing block to translate towards the first steel strip or the second steel strip, so as to move above the first steel strip or the second steel strip; the fifth driving member is further configured to drive the pressing block away from the first steel strip or the second steel strip, so as to avoid the first steel strip or the second steel strip.

[0031] A pressing-in component with a simple structure is provided. The fourth driving member drives the connecting plate and the pressing block thereon to descend, so that the pressing block can push down the first side edge of the first steel strip or the second steel strip during the descending process. The connecting plate and the pressing block thereon can pass through the gap between the two extrusion rods until the first steel strip or the second steel strip is pushed to the corresponding installation position. In addition, since the pressing block is installed on the fifth driving member, the fifth driving member can drive the pressing block to switch between the pressing position and the avoiding position. When it is necessary to receive and cache the first steel strip or the second steel strip, the fifth driving member drives the pressing block to move to the avoiding position to avoid the first steel strip or the second steel strip. When it is necessary to push down the first steel strip or the second steel strip, the fifth driving member drives the pressing block to move to the pressing position, ensuring that when the fourth driving member drives the connecting plate to descend, the pressing block can press on the first side edge of the first steel strip or the second steel strip.

[0032] In some embodiments, the pressing-in component further includes a supporting member arranged on the driving end of the fifth driving member. The supporting member is located below the pressing block, and the vertical distance between the supporting member and the pressing block is greater than the height of the first steel strip or the second steel strip. The supporting member and the pressing block cooperate to limit the vertical movement amount of the first steel strip and the second steel strip.

[0033] By arranging the supporting member on the driving end of the fifth driving member, when the pressing block pushes down the first steel strip or the second steel strip, the supporting member can support and limit the first steel strip or the second steel strip from below, avoiding excessive sliding of the first steel strip or the second steel strip and deviation from the corresponding installation position.

[0034] In some embodiments, the equipment for sleeving a steel strip on a battery cell module further includes a first guiding mechanism disposed on a lifting bracket. When the pressing mechanism presses the first steel strip or the second steel strip downward, the first guiding mechanism supports and guides two opposite second side edges of the first steel strip or the second steel strip from the inside, so that the first steel strip or the second steel strip is sleeved onto the battery cell module along the first guiding mechanism, and the second side edges are parallel to the first horizontal direction. The first guiding mechanism includes two first guiding components disposed at both ends of the lifting bracket, and the two first guiding components cooperate to support and guide two second side edges of the first steel strip or the second steel strip from both ends. The first guiding component includes a distance-adjusting driving member, a first guiding block, and a second guiding block, wherein: the distance-adjusting driving member is disposed on the lifting bracket, the first guiding block and the second guiding block are relatively connected to the driving end of the distance-adjusting driving member along the second horizontal direction, the distance-adjusting driving member is configured to drive the first guiding block and the second guiding block to slide closer to each other or slide apart from each other to adjust the distance between the first guiding block and the second guiding block, and the second horizontal direction is perpendicular to the first horizontal direction. When the lifting driving mechanism drives the lifting bracket to descend in place, the first guiding block and the second guiding block are tightly attached to both side edges of the battery cell module. When the pressing mechanism presses the first steel strip or the second steel strip downward, the first guiding block and the second guiding block support and guide two second side edges of the first steel strip or the second steel strip from the inside, so that the first steel strip or the second steel strip is sleeved onto the battery cell module.

[0035] There is a height difference between the first steel strip or the second steel strip to be installed above the battery cell module and the battery cell module. By providing the first guiding mechanism, the first steel strip or the second steel strip to be installed above the battery cell module can smoothly transition from above the battery cell module to the battery cell module under the guidance and support of the first guiding mechanism. By configuring the first guiding mechanism to include two first guiding components, the two first guiding components cooperate to support and guide two second side edges of the first steel strip or the second steel strip from both ends, ensuring the guiding effect on two second side edges of the first steel strip or the second steel strip, enabling the first steel strip or the second steel strip to smoothly slide down and transition to the battery cell module, and preventing the first steel strip or the second steel strip from tilting in position.

[0036] By configuring the first guiding component to include a distance-adjusting driving member, a first guiding block, and a second guiding block, the first guiding component can not only guide the first steel strip or the second steel strip but also avoid it. Specifically, in the initial state, the first guiding block and the second guiding block move closer to each other to avoid the first steel strip or the second steel strip, ensuring that the stockpiling mechanism can smoothly receive and cache the first steel strip or the second steel strip.

[0037] When it is necessary to install the first steel belt or the second steel belt, the distance-adjusting driving member drives the first guiding block and the second guiding block to slide apart to both sides, so that the distance between the first guiding block and the second guiding block is adapted to the width of the battery cell module, and the first guiding block and the second guiding block support the two second side edges of the first steel belt or the second steel belt from the inside. Subsequently, the lifting driving mechanism drives the lifting bracket to descend in place, so that the first guiding block and the second guiding block are closely attached to the two side edges of the battery cell module. In this way, when the pressing mechanism pushes the steel belt downward, the first guiding block and the second guiding block guide the two second side edges of the steel belt from the inside, and finally the steel belt is sleeved on the battery cell module.

[0038] In some embodiments, the battery cell module steel belt sleeving device further includes a second guiding mechanism disposed on the lifting bracket; when the pressing mechanism pushes the first steel belt or the second steel belt downward, the second guiding mechanism is configured to support and guide two opposite first side edges of the first steel belt or the second steel belt from the inside, so that the first steel belt or the second steel belt slides downward under the guidance of the second guiding mechanism to the first installation position or the second installation position, and the first side edge is perpendicular to the first horizontal direction; the second guiding mechanism includes two second guiding components disposed at both ends of the lifting bracket, and the two second guiding components cooperate to support and guide two first side edges of the first steel belt or the second steel belt from both ends; the second guiding component includes a sixth driving member and a guiding plate, the sixth driving member is disposed on the lifting bracket, and the guiding plate is connected to the driving end of the sixth driving member; the sixth driving member is used to drive the guiding plate to descend so that the guiding plate is closely attached to the end face of the battery cell module.

[0039] By providing the second guiding mechanism, when the pressing mechanism pushes the first steel belt or the second steel belt downward, the second guiding mechanism supports and guides two opposite first side edges of the first steel belt or the second steel belt from the inside, so that the first steel belt or the second steel belt slides downward under the guidance of the second guiding mechanism to the corresponding installation position, preventing the first steel belt or the second steel belt from getting stuck and tilting in position during the downward sliding process.

[0040] By configuring the second guiding mechanism to include two second guiding components, the two second guiding components cooperate to support and guide two first side edges of the first steel belt or the second steel belt from both ends, ensuring the guiding effect on the two first side edges of the first steel belt or the second steel belt, ensuring that the first steel belt or the second steel belt can smoothly descend along the battery cell module in a horizontal state to the corresponding installation position, and preventing the first steel belt or the second steel belt from tilting or getting stuck in position during the downward sliding process.

[0041] In some embodiments, the battery cell module steel belt sleeving device further includes a pressing plate disposed at the bottom of the lifting bracket; when the lifting driving mechanism drives the lifting bracket to descend in place, the pressing plate presses against the upper surface of the battery cell module.

[0042] By arranging a pressure plate at the bottom of the lifting bracket, when the lifting drive mechanism drives the lifting bracket to descend 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.

[0070] 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 accompanying drawings and specific implementation manners.

[0071] As Figures 2 to 3 shown, the cell module sleeving steel strip device in the embodiment of the present application includes a loading platform 1, a lifting drive mechanism 3, a lifting bracket 4, a storage mechanism, a pressing-in mechanism, and two squeezing mechanisms 2, where:

[0072] The loading platform 1 is used to carry the cell module 100. The two squeezing mechanisms 2 are arranged at both ends of the loading platform 1 along the first horizontal direction, and the two squeezing mechanisms 2 are configured to squeeze both ends of the cell module 100 in the length direction located on the loading platform 1 from both ends. For example, both the first horizontal direction and the length direction of the cell module 100 are the X-axis direction.

[0073] The lifting bracket 4 is arranged above the loading platform 1. The lifting bracket 4 is connected to the driving end of the lifting drive mechanism 3. The storage mechanism and the pressing-in mechanism are both arranged on the lifting bracket 4. The storage mechanism caches the first steel strip 201 and the second steel strip 202 that are spaced apart from bottom to top.

[0074] The lifting drive mechanism 3 is configured to drive the lifting bracket 4 to descend towards the battery cell module 100, so that the pressing mechanism approaches the battery cell module 100. The pressing mechanism is configured to push down the first steel belt 201 cached by the material storage mechanism, so that after the first steel belt 201 is sleeved on the battery cell module 100, it slides down along the side wall of the battery cell module 100 to the first installation position.

[0075] The pressing mechanism is further configured to push down the second steel belt 202, so that after the second steel belt 202 is sleeved on the battery cell module 100, it slides down along the side wall of the battery cell module 100 to the second installation position, and the second installation position is above the first installation position.

[0076] In one embodiment, the steel belts to be installed are stacked in the material frame from bottom to top. In addition, the lifting drive mechanism 3 is installed on the moving module, and the moving module is used to drive the lifting bracket 4 and the material storage mechanism and the pressing mechanism thereon to translate. The optional belt sleeving process of the battery cell module belt sleeving device in the embodiment of the present application is as follows:

[0077] First, the battery cell module 100 is loaded onto the carrying platform 1, and the two pressing mechanisms 2 are controlled to press the two ends of the battery cell module 100 in the length direction located on the carrying platform 1 from both ends.

[0078] The moving module drives the lifting bracket 4 to translate, so that the lifting bracket 4 moves above the material frame. Subsequently, the lifting drive mechanism 3 drives the lifting bracket 4 to descend, so that the material storage mechanism penetrates into the steel belt (i.e., the second steel belt 202) currently at the top layer of the material frame, and the material storage mechanism immediately picks up the second steel belt 202 to implement the caching of the second steel belt 202.

[0079] The lifting drive mechanism 3 continues to drive the lifting bracket 4 to descend, so that the material storage mechanism and the pressing mechanism penetrate into the steel belt (i.e., the first steel belt 201) currently at the top layer of the material frame. The material storage mechanism immediately caches the first steel belt 201, and the pressing mechanism holds the first steel belt 201.

[0080] Subsequently, the moving module drives the lifting bracket 4 to translate, so that the lifting bracket 4 moves above the battery cell module 100. The lifting drive mechanism 3 drives the lifting bracket 4 to descend, so that the pressing mechanism and the first steel belt 201 approach the battery cell module 100.

[0081] Then, the pressing mechanism pushes down the first steel belt 201, so that after the first steel belt 201 is sleeved on the battery cell module 100, it slides down along the side wall of the battery cell module 100 until it reaches the corresponding first installation position.

[0082] Next, the pressing mechanism holds the second steel strip 202 from the stock-holding mechanism, and the stock-holding mechanism releases the second steel strip 202. The pressing mechanism pushes the second steel strip 202 downward, so that after the second steel strip 202 is sleeved on the battery cell module 100, it slides down along the side wall of the battery cell module 100 until it reaches the corresponding second installation position.

[0083] It can be seen that through the cooperation of the stock-holding mechanism and the pressing mechanism, the battery cell module steel strip sleeving device provided by the embodiment of the present application realizes the buffering of the first steel strip and the second steel strip. The pressing mechanism first pushes the received first steel strip 201 downward to the first installation position outside the battery cell module 100, and then takes the second steel strip from the stock-holding mechanism and pushes the second steel strip downward to the second installation position, realizing the separate installation of the first steel strip and the second steel strip on the battery cell module. In this process, it is not necessary to send the first steel strip and the second steel strip twice, thereby improving the efficiency of sleeving the steel strip on the battery cell module.

[0084] Optionally, the stock-holding mechanism includes two buffer components 5 arranged at both ends of the lifting bracket 4. The two buffer components 5 are used to support two opposite first side edges of the second steel strip 202, and the first side edge is perpendicular to the first horizontal direction. The two buffer components 5 cooperate from both sides to support two opposite first side edges of the second steel strip 202, realizing the stable buffering of the second steel strip 202 and preventing the second steel strip 202 from tilting. The first side edge of the steel strip is generally the short side of the steel strip.

[0085] As Figures 5 to 8 shown, the buffer component 5 includes a first driving member 51 and a buffer plate 52. The first driving member 51 is arranged on the lifting bracket 4, and the buffer plate 52 is connected to the driving end of the first driving member 51. When the first driving member 51 drives the buffer plate 52 to move towards the second steel strip 202, the buffer plate 52 extends below the first side edge of the second steel strip 202 to support the first side edge of the second steel strip 202. When the first driving member 51 drives the buffer plate 52 to move away from the second steel strip 203, the buffer plate 52 withdraws from below the first side edge of the second steel strip 202.

[0086] The first driving member 51 can adopt various existing linear driving modules capable of driving the buffer plate 52 to move along the first horizontal direction, such as air cylinders, lead screw motors, etc.

[0087] The stock-holding mechanism and the pressing mechanism cooperate with each other, and the optional process of receiving and buffering the first steel strip 201 and the second steel strip 202 is as follows:

[0088] In the initial state, the buffer plates 52 of the two buffer components 5 are in the initial positions close to the corresponding first driving members 51.

[0089] The lifting drive mechanism 3 drives the lifting bracket 4 to descend towards the material box until the buffer plates 52 of the two buffer components 5 descend below the two first sides of the second steel belt 202. Subsequently, the first driving members 51 of the two buffer components 5 drive the corresponding buffer plates 52 to extend towards one first side of the second steel belt 202, so that the buffer plates 52 of the two buffer components 5 respectively support one first side of the second steel belt 202.

[0090] The lifting drive mechanism 3 drives the lifting bracket 4 to continue descending, and the pressing mechanism enters the first steel belt 201 and then holds the first steel belt 201.

[0091] Next, the material storage mechanism and the pressing mechanism cooperate with each other to successively fit the second steel belt 202 and the first steel belt 201 onto the battery cell module 100. The specific process is as follows:

[0092] After the lifting bracket 4 moves above the battery cell module 100, the lifting drive mechanism 3 drives the lifting bracket 4 to descend, so that the pressing mechanism and the first steel belt 201 approach the battery cell module 100.

[0093] Subsequently, the pressing mechanism pushes the first steel belt 201 downward, so that after the first steel belt 201 is fitted 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 installation position.

[0094] Next, the pressing mechanism holds the second steel belt 202 cached on the buffer component 5. At the same time, the first driving members 51 of the two buffer components 5 drive the corresponding buffer plates 5 to retract towards the first driving members 51, so that the buffer plates 5 are withdrawn from below the first side of the corresponding second steel belt 202.

[0095] Subsequently, the pressing mechanism pushes the second steel belt 202 downward, so that after the second steel belt 202 is fitted 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 installation position.

[0096] As Figure 7 shown, in order to ensure that the first side of the second steel belt 202 can be stably supported on the buffer plate 52. Optionally, the buffer component 5 includes two buffer plates 52, and the two buffer plates 52 are arranged side by side along the second horizontal direction (for example, the Y-axis direction), and the second horizontal direction is perpendicular to the first horizontal direction. The two buffer plates 52 support one first side of the second steel belt 202 from two different positions.

[0097] As Figures 2 to 7 shown, optionally, the material storage mechanism further includes two spreading components 6 arranged at both ends of the lifting bracket 4, and the two spreading components 6 are configured to move away from each other along the first horizontal direction to simultaneously spread two opposite first sides of the first steel belt 201 and / or the second steel belt 202.

[0098] The stock storage mechanism and the pressing mechanism cooperate with each other, and the optional process of receiving and caching the first steel belt 201 and the second steel belt 202 is as follows:

[0099] In the initial state, the buffer plates 52 of the two buffer components 5 are at the initial positions close to the corresponding first driving members 51, and the two spreading components 6 are close to each other.

[0100] The lifting drive mechanism 3 drives the lifting bracket 4 to descend towards the material box until the buffer plates 52 of the two buffer components 5 descend below the two first sides of the second steel belt 202. At the same time, the two spreading components 6 also descend through the second steel belt 202.

[0101] Subsequently, the first driving members 51 of the two buffer components 5 drive the corresponding buffer plates 52 to extend towards one of the first sides of the second steel belt 202, so that the buffer plates 52 of the two buffer components 5 respectively support one of the first sides of the second steel belt 202.

[0102] The lifting drive mechanism 3 drives the lifting bracket 4 to continue descending until the two spreading components 6 penetrate into the first steel belt 201. The two spreading components 6 move away from each other along the first horizontal direction, so as to spread the two first sides of the first steel belt 201, and the pressing mechanism holds the first steel belt 201. Of course, when the length of the spreading component 6 along the vertical direction is long enough, when the spreading component 6 spreads the first steel belt 201, it also synchronously spreads the two first sides of the second steel belt 202.

[0103] Then, the stock storage mechanism and the pressing mechanism cooperate with each other to successively sleeved the first steel belt 201 and the second steel belt 202 onto the battery cell module 100, and the specific process is as follows:

[0104] After the lifting bracket 4 moves above the battery cell module 100, the lifting drive mechanism 3 drives the lifting bracket 4 to descend, so that the pressing mechanism and the first steel belt 201 approach the battery cell module 100.

[0105] Subsequently, the pressing mechanism pushes down the first steel belt 201. At the same time, the two spreading components 6 move towards the middle to release the first steel belt 201. The released first steel belt 201 slides down along the side wall of the battery cell module 100 after being sleeved onto the battery cell module 100 under the pushing of the pressing mechanism until it reaches the corresponding first installation position.

[0106] Next, the pressing mechanism rises and holds the second steel belt 202 cached on the buffer component 5. At the same time, the first driving members 51 of the two buffer components 5 drive the corresponding buffer plates to retract towards the first driving members 51, so that the buffer plates are withdrawn from below the first sides of the corresponding second steel belts 202 to release the support for the first sides of the second steel belts 202.

[0107] Finally, the pressing mechanism pushes the second steel strip 202 downward, so that the second steel strip 202 is sleeved onto the battery cell module 100 and then slides down along the side wall of the battery cell module 100 until it reaches the corresponding second installation position.

[0108] It can be seen that by setting up two support components 6, the first steel belt 201 and / or the second steel belt 202 are tightened, so that when the pressing mechanism pushes the first steel belt 201 or the second steel belt 202 downward, the first steel belt 201 or the second steel belt 202 can be more smoothly put down onto the battery cell module 100.

[0109] like Figure 3 and Figure 7 As shown, optionally, the support assembly 6 includes a second driving member 61, a movable plate 62 and two support rods 63, wherein: the second driving member 61 is arranged on the lifting bracket 4, the movable plate 62 is slidably connected to the lifting bracket 4 and is connected to the driving end of the second driving member 61, and the two support rods 63 are arranged at intervals at the end of the movable plate 62 along the second horizontal direction (for example, the Y-axis direction), and the support rods 63 extend along the vertical direction, and the second horizontal direction is perpendicular to the first horizontal direction.

[0110] The second driving member 61 is used to drive the moving plate 62 to slide along the first horizontal direction, so as to drive the two support rods 63 to open the first side edge of the first steel belt 201 and / or the second steel belt 202 from the inner side of the first steel belt 201 and / or the second steel belt 202. The first side edge of the steel belt is generally the short side of the steel belt.

[0111] The process of the opening component 6 opening the first side edge of the first steel strip 201 or the second steel strip 202 is as follows:

[0112] In the initial state, the two struts 63 of the propping assembly 6 are in a retracted position close to the lifting bracket 4, and the distance between the two struts 63 of the propping assembly 6 located at the first end of the lifting bracket 4 and the two struts 63 of the propping assembly 6 located at the second end of the lifting bracket 4 is less than the length of the second side of the steel belt (generally the long side of the steel belt), so that the struts 63 of the two propping assemblies 6 can extend into the first steel belt 201 and / or the second steel belt 202.

[0113] Subsequently, the two support rods 63 of the support assembly 6 at the first end of the lifting bracket 4 are driven by the second driving member 61 to extend away from the lifting bracket 4 to the first side of the lifting bracket 4, and at the same time, the two support rods 63 of the support assembly 6 at the second end of the lifting bracket 4 are driven by the second driving member 61 to extend away from the lifting bracket 4 to the second side of the lifting bracket 4. In this way, the two opposite first side edges of the first steel belt 201 and / or the second steel belt 202 are respectively tightened by the two support rods 63.

[0114] Optionally, the distance between the two support rods 63 of the support assembly 6 is equal to the length of the first side of the steel strip. In this way, when the second driving member 61 drives the moving plate 62 to slide along the first horizontal direction, the two support rods 63 can respectively press the two corners of the first steel strip 201 or the second steel strip 202 from the inside.

[0115] The second driving member 61 can adopt various existing linear driving modules that can drive the moving plate 62 to slide along the first horizontal direction, such as a cylinder, a screw motor, etc.

[0116] like Figure 7 As shown, optionally, the two cache plates 52 of the cache assembly are located between the two support rods 63 of the support assembly 6 at corresponding positions, so that the cache plates 52 can be freely retracted or extended under the drive of the first driving member 51 without interfering with the two support rods 63.

[0117] like Figure 2 and Figures 9 to 10 As shown, optionally, the extrusion mechanism 2 includes a base 21 and at least two extrusion components 22 arranged on the base 21 at intervals in the vertical direction, and each extrusion component 22 can independently extend or retract along a first horizontal direction (for example, the X-axis direction) to extrude or disengage the battery cell module 100 from a corresponding pushing position.

[0118] Since the pressing assembly 22 of the pressing mechanism 2 can move toward or away from the battery module 100, when the first steel belt 201 or the second steel belt 202 slides from top to bottom along the battery module 100, each pressing assembly 22 can avoid the first steel belt 201 or the second steel belt 202, thereby ensuring that the first steel belt 201 or the second steel belt 202 can slide to the corresponding installation position. When the first steel belt 201 or the second steel belt 202 passes the pushing position of each pressing assembly 22, the pressing assembly 22 immediately resumes pressing the battery module 100.

[0119] In addition, since the extrusion mechanism 2 includes at least two extrusion components 22 spaced apart in the vertical direction, when one of the extrusion components 22 detaches from the battery cell module 100 to avoid the first steel strip 201 or the second steel strip 202, the other extrusion components 22 continue to squeeze the battery cell module 100, thereby ensuring that the battery cell module 100 is always in a squeezed state during the installation of the first steel strip 201 or the second steel strip 202.

[0120] The following will take the example that the extrusion mechanism 2 includes two extrusion assemblies 22 to exemplarily describe the installation process of the first steel strip 201 and the second steel strip 202 implemented by the extrusion mechanism 2 in cooperation with the clamping mechanism:

[0121] First, load the battery cell module 100 onto the carrier table 1, and control the two pressing mechanisms 2 to move towards the carrier table 1 so that the two pressing mechanisms 2 approach the end faces of the battery cell module 100 along the length direction respectively.

[0122] Subsequently, control the two pressing components 22 of the pressing mechanism 2 to extend towards the battery cell module 100 so that the two pressing components 22 of the pressing mechanism 2 press the end face of the battery cell module 100 from the corresponding pressing positions. Of course, the pressing position of the first pressing component 22 located above is higher than the pressing position of the second pressing component 22 located below.

[0123] The pressing mechanism starts to push down the first steel strip 201 so that after the first steel strip 201 is sleeved on the battery cell module 100, it slides down along the side wall of the battery cell module 100 until it reaches the corresponding first installation position. Among them, the first installation position is below the pressing position of the second pressing component 22.

[0124] During the sliding process of the first steel strip 201, the first steel strip 201 needs to cross the pressing positions of the first pressing component 22 and the second pressing component 22 in sequence. Specifically, when the first steel strip 201 is about to reach the pressing position of the first pressing component 22, the first pressing component 22 retracts away from the battery cell module 100 to disengage from the battery cell module 100, so as to implement an avoidance of the first steel strip 201. After the first steel strip 201 crosses the pressing position of the first pressing component 22, the first pressing component 22 extends again to resume pressing the battery cell module 100. Similarly, when the first steel strip 201 is about to reach the pressing position of the second pressing component 22, the second pressing component 22 retracts away from the battery cell module 100 to disengage from the battery cell module 100, so as to implement an avoidance of the first steel strip 201. After the first steel strip 201 crosses the pressing position of the second pressing component 22, the second pressing component 22 extends again to resume pressing the battery cell module 100.

[0125] So far, the installation of the first steel strip 201 is completed. Control the pressing mechanism to return to the initial state, and the lifting drive mechanism 3 drives the lifting bracket 4 to rise and return to its position.

[0126] The pressing mechanism starts to push down the second steel strip 202 so that after the second steel strip 202 is sleeved on the battery cell module 100, it slides down along the side wall of the battery cell module 100 until it reaches the corresponding second installation position. Among them, the second installation position is between the pressing positions of the first pressing component 22 and the second pressing component 22.

[0127] During the downward sliding process, the second steel belt 202 needs to pass through the pressing position of the first pressing assembly 22. When the second steel belt 202 is about to reach the pressing position of the first pressing assembly 22, the first pressing assembly 22 retracts away from the battery cell module 100 to disengage from the battery cell module 100, thereby implementing an avoidance of the second steel belt 202. After the second steel belt 202 passes over the pressing position of the first pressing assembly 22, the second pressing assembly 22 extends again to resume the pressing of the battery cell module 100.

[0128] Thus, the installation of the second steel belt 202 is completed. The control pressing mechanism is restored to the initial state, and the lifting drive mechanism 3 drives the lifting bracket 4 to rise and return to its position.

[0129] Subsequently, the two pressing assemblies 22 of the pressing mechanism 2 are controlled to retract away from the battery cell module 100 to release the battery cell module 100. Finally, the two pressing mechanisms 2 are controlled to move away from the carrier 1 and return to their positions to facilitate the blanking device to blank the battery cell module 100 with the steel belt installed from the carrier 1.

[0130] Optionally, the pressing assembly 22 includes a third driving member 221, a pressing plate 222, and two pressing rods 223, where: the third driving member 221 is installed on the base 21, the pressing plate 222 is slidably installed on the base 21 along the first horizontal direction, and the two pressing rods 223 are installed on the side of the pressing plate 222 facing the carrier 1. The third driving member 221 is configured to drive the pressing plate 222 to approach or move away from the battery cell module 100 on the carrier 1, so that the two pressing rods 223 press or move away from the battery cell module 100 on the carrier 1. The gap between the two pressing rods 223 allows the pressing mechanism to pass vertically through.

[0131] By setting the pressing components of the pressing assembly 22 as two pressing rods 223 with a gap therebetween, on the one hand, the pressing assembly 22 can press the battery cell module 100 from two different positions, so that the ends of the battery cell module 100 are uniformly stressed, preventing the battery cells in the battery cell module 100 from being damaged due to excessive local stress. On the other hand, the gap between the two pressing rods 223 of the pressing assembly 22 can implement an avoidance of the pressing mechanism, enabling the pressing mechanism to pass downward through the pressing assembly 22 to push the first steel belt 201 or the second steel belt 202 to the first installation position or the second installation position below the pressing assembly 22.

[0132] The third driving member 221 can adopt various existing linear driving modules capable of driving the pressing plate 222 to slide along the first horizontal direction, such as air cylinders or lead screw motors.

[0133] As is known to those skilled in the art, for existing extrusion assemblies, the driving member (such as a cylinder) drives the extrusion member to extrude the battery cell module along the length direction of the battery cell module. The extrusion assembly with such a structure requires the driving member to have a large thrust, thus increasing the equipment cost. In addition, the driving member bears a large reaction force from the battery cell module, resulting in easy damage to the driving member.

[0134] To overcome the above-mentioned technical defects of the existing extrusion assemblies, optionally, as Figure 10 shown, the extrusion assembly 22 further 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, 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. The pushing block 224 is slidably connected to the base 21 and connected to the driving end of the third driving member 221. A pushing inclined surface 227 is formed on the pushing block 224, and the pushing wheel 225 on the extrusion plate 224 abuts against the pushing inclined surface 227. The third driving member 221 is configured to drive the pushing block 224 to reciprocally slide along the second horizontal direction (such as the Y-axis direction) so that the pushing block 224 switches between a pushing position and a release position, and the second horizontal direction is perpendicular to the first horizontal direction.

[0135] When the third driving member 221 drives the pushing block 224 to slide from the release position towards the pushing position, the pushing inclined surface 227 of the pushing block 224 pushes the extrusion plate 222 to slide towards the battery cell module 100 along the first horizontal direction through the pushing wheel 226, so as to drive the extrusion end of the extrusion plate 222 to extrude the end of the battery cell module 100. During this process, the return spring 226 elongates under the pulling of the extrusion plate 222.

[0136] When the third driving member 221 drives the pushing block 224 to slide from the pushing position towards the release position, the pushing inclined surface 227 of the pushing block 224 gradually disengages from the pushing wheel 226, and the return spring 226 loses pressure and retracts, thereby driving the extrusion plate 222 to slide away from the battery cell module 100 along the first horizontal direction to reset, so that the two extrusion rods 223 disengage from the end of the battery cell module 100.

[0137] It can be seen that by setting the pushing block 224, the pushing wheel 225 and the return spring 226, the third 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 through the pushing inclined surface 227 thereon, thereby driving the extrusion plate 222 to extrude the battery cell module 100 parallel to the length direction of the battery cell module 100.

[0138] Compared with the traditional direct drive where the extrusion plate 222 extrudes the battery cell module 100 parallel to the length direction of the battery cell module, the third driving member 221 only needs to output a smaller thrust to achieve the same extrusion effect on the battery cell module 100, thereby reducing the equipment cost. In addition, the reaction force of the battery cell module 100 is mainly applied to the base 21, and the reaction force of the third driving member 221 from the battery cell module 100 is reduced, thereby reducing the risk of damage to the third driving member 221 and extending the service life of the extrusion mechanism.

[0139] As Figure 2 and Figure 9 shown, optionally, the extrusion mechanism 2 further includes a base 23 and a pressing component 24. The base 21 is slidably mounted on the base 23 along a first horizontal direction. The pressing component 24 includes a pressing plate 242 and a pressing spring 241. The pressing plate 242 is mounted at 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. The pressing end of the pressing plate 242 on the base 21 is continuously pressed against the end of the battery cell module 100 on the carrier 1 under the pressure of the pressing spring 241.

[0140] By slidably mounting the base 21 on the base 23 and arranging the pressing component 24. When it is necessary to perform extrusion on the battery cell module 100 on the carrier 1, first control the base 23 to move to a target position close to the battery cell 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 cell module 100 under the pressure of the pressing spring 241 to perform fixed positioning on the end of the battery cell module 100.

[0141] On the one hand, the pressing component 24 performs pre-positioning on the battery cell module, thus facilitating the extrusion component 22 to perform extrusion on the battery cell module 100. In addition, the pressing component 24 is continuously pressed against the end of the battery cell module 100 during the process of sleeving the steel belt, that is, the pressing component 24 can cooperate to perform extrusion on the battery cell module 100, thereby increasing the extrusion force of the extrusion mechanism 2 on the battery cell module 100.

[0142] In addition, when the pressing component 24 is pressed against the end of the battery cell module 100, the extrusion component 22 has already approached the battery cell module 100. Therefore, the extrusion component 22 only needs to move a small stroke towards the battery cell module 100 to perform extrusion on the end of the battery cell module 100.

[0143] Of course, in order to prevent the pressing component 24 from blocking the downward sliding of the first steel belt 201 and the second steel belt 202, the pressing component 24 is located below the first installation position corresponding to the first steel belt 201. For example, the pressing position of the pressing component 24 is on the end plate at the end of the battery cell module 100.

[0144] AsFigure 10 As shown, optionally, when the pressing block 224 is in the release position, the pressing end of the pressing plate 242 protrudes beyond the ends of the two extrusion rods 223 in the first horizontal direction. In this way, it can be ensured 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 is continuously pressed against the end of the battery cell module 100 under the pressure of the pressing spring 241, while the extrusion end of the extrusion rod 223 has not yet contacted the battery cell module 100, and there is a moving space between the extrusion rod 223 and the battery cell module 100. That is, after the extrusion rod 223 is pressed against the end of the battery cell module 100, the extrusion rod 223 can extend towards the battery cell module to extrude the end of the battery cell module 100, and retract away from the battery cell module 100 to disengage from the end of the battery cell module 100.

[0145] To prevent the pressing assembly 24 from blocking the downward sliding of the first steel belt 201 or the second steel belt 202, the pressing assembly 24 is located below the first installation position of the first steel belt 201. For example, the pressing position of the pressing assembly 24 is on the end plate at the end of the battery cell module 100. Of course, to prevent the pressing assembly 24 from touching the pressing-in mechanism, as Figure 10 As shown, optionally, two pressing rods are provided at the pressing end of the pressing plate 242, and the pressing plate 242 presses the end of the battery cell module 100 through the two pressing rods. The gap between the two pressing rods can be used to avoid the pressing-in mechanism, thereby preventing contact with the pressing-in mechanism.

[0146] Optionally, the bases 23 of the two extrusion mechanisms 2 are respectively slidably mounted at both ends of the carrier 1 along the first horizontal direction. Correspondingly, the battery cell module steel belt sleeving device in the embodiment of the present application further includes two translation driving mechanisms 110 corresponding to the two extrusion mechanisms 2 one by one, and the driving ends of the two translation driving mechanisms 100 are respectively fixedly connected to the bases of the two extrusion mechanisms 2.

[0147] The two translation driving mechanisms 110 are configured to synchronously drive the two extrusion mechanisms 2 to slide closer to the carrier 1, so that the two extrusion mechanisms 2 approach the battery cell module 100 located on the carrier 1.

[0148] The translation driving mechanism 110 can adopt an existing linear driving module capable of driving the extrusion mechanism 2 to slide towards or away from the carrier 1. For example, the translation driving mechanism 110 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 base 23 is driven to slide along the guide rail through the screw nut, thereby driving the extrusion mechanism 2 to slide towards or away from the carrier 1. Of course, the translation driving mechanism 110 can also adopt a linear driving module with other structures such as a cylinder driving module.

[0149] Such as Figure 2As shown, optionally, the pressing mechanism includes two pressing components 7 disposed at two ends of the lifting bracket 4 in the length direction. The two pressing components 7 are configured to respectively push two opposite first side edges of the first steel strip 201 or the second steel strip 202.

[0150] Driven by the lifting bracket 4, the two pressing components 7 synchronously press down the two first side edges of the first steel strip 201 or the second steel strip 202. In this way, it can be ensured that the first steel strip 201 or the second steel strip 202 slides down smoothly in a horizontal state until it reaches the corresponding installation position, preventing the first steel strip 201 or the second steel strip 202 from tilting during the sliding process, and preventing the first steel strip 201 or the second steel strip 202 from jamming with the first side edge of the battery cell module 100 during the sliding process.

[0151] As Figure 4 shown, optionally, the pressing component 7 includes a fourth driving member 71, a connecting plate 72, a fifth driving member 73 and a pressing block 74, where: the fourth driving member 71 is disposed on the lifting bracket 4, the connecting plate 72 is connected to the driving end of the fourth driving member 71, the fifth driving member 73 is disposed at the bottom of the connecting plate 72, and the pressing block 74 is mounted on the driving end of the fifth driving member 73. The gap between the two pressing rods 223 allows the connecting plate 72 and the pressing block 74 to pass through vertically.

[0152] When receiving and caching the first steel strip 201 or the second steel strip 202, the fifth driving member 73 drives the pressing block 74 away from the first steel strip 201 or the second steel strip 202 to avoid the first steel strip 201 or the second steel strip 202.

[0153] The lifting drive mechanism 3 drives the lifting bracket 4 to descend in place. When it is necessary to press the first steel strip 201 or the second steel strip 202, the fifth driving member drives the pressing block 74 to translate towards the first steel strip 201 or the second steel strip 202 to move above the first steel strip 201 or the second steel strip 202. Subsequently, the fourth driving member 71 drives the connecting plate 72 to descend to drive the pressing block 74 to press down the first side edge of the first steel strip 201 or the second steel strip 202 until the first steel strip 201 or the second steel strip 202 slides along the battery cell module 100 to the corresponding installation position.

[0154] In order to improve the uniform stress of the first side edge of the first steel strip 201 or the second steel strip 202 and prevent the first side edge of the first steel strip 201 or the second steel strip 202 from tilting during the downward sliding process, resulting in jamming. Optionally, the pressing component 7 includes two pressing blocks 74, and the two pressing blocks 74 are arranged side by side in the second horizontal direction. When the fourth driving member 71 drives the connecting plate 72 to descend, the two pressing blocks 74 synchronously press down the first side edge of the first steel strip 201 or the second steel strip 202 from two different positions.

[0155] Both the fourth driving member 71 and the fifth driving member 73 can adopt various existing linear driving modules, such as air cylinders, lead screw motors, etc.

[0156] Optionally, the pressing-in assembly 7 further includes a supporting member 75 disposed on the driving end of the fifth driving member 73. The supporting member 75 is located below the pressing block 74. The distance between the supporting member 75 and the pressing block 74 in the vertical direction is greater than the height of the first steel belt 201 or the second steel belt 202. The supporting member 75 and the pressing block 74 cooperate to define the movement amount of the first steel belt 201 and the second steel belt 202 in the vertical direction.

[0157] By providing the supporting member 75 located below the pressing block 74, when the pressing block 74 pushes down the first steel belt 201 or the second steel belt 202, the supporting member 75 can support and limit the first steel belt 201 or the second steel belt 202, preventing the first steel belt 201 or the second steel belt 202 from detaching from the pressing-in assembly 7 and deviating from the preset position.

[0158] As Figure 3 , Figure 4 and Figure 8 As shown, optionally, the cell module steel belt sleeving device in the embodiment of the present application further includes a first guiding mechanism disposed on the lifting bracket 4. When the pressing-in mechanism pushes down the first steel belt 201 or the second steel belt 202, the first guiding mechanism supports and guides two opposite second sides of the first steel belt 201 or the second steel belt 202 from the inside, so that the first steel belt 201 or the second steel belt 202 is sleeved onto the cell module 100 along the first guiding mechanism, and the second sides are parallel to the first horizontal direction. The second sides are generally the long sides of the steel belt. There is a height difference between the first steel belt 201 or the second steel belt 202 to be installed above the cell module 100 and the cell module 100. By providing the first guiding mechanism, the first steel belt 201 or the second steel belt 202 to be installed above the cell module 100 can smoothly transition from above the cell module to the cell module 100 under the guidance and support of the first guiding mechanism.

[0159] Optionally, the first guiding mechanism includes two first guiding components 8 disposed at both ends of the lifting bracket 4. The two first guiding components 8 cooperate to support and guide two second sides of the first steel belt 201 or the second steel belt 202 from both ends. That is, when the pressing-in mechanism pushes down the first steel belt 201 or the second steel belt 202, the two second sides of the first steel belt 201 or the second steel belt 202 are sleeved onto the two first guiding components 8 downward and transition to the cell module 100 under the support and guidance of the two first guiding components 8.

[0160] By arranging the first guiding mechanism to include two first guiding components 8, the two first guiding components 8 cooperate to support and guide the two second side edges of the first steel belt 201 or the second steel belt 202 from both ends, ensuring the guiding effect on the two second side edges of the first steel belt 201 or the second steel belt 202, enabling the first steel belt 201 or the second steel belt 202 to slide down smoothly and transition onto the battery cell module 100, and preventing the first steel belt 201 or the second steel belt 202 from tilting in position.

[0161] As Figure 8 shown, optionally, the first guiding component 8 includes a distance adjustment driving member 81, a first guiding block 82 and a second guiding block 83, wherein: the distance adjustment driving member 81 is arranged on the lifting bracket 4, the first guiding block 82 and the second guiding block 83 are relatively connected to the driving end of the distance adjustment driving member 81 along the second horizontal direction, and the distance adjustment driving member 81 is used to drive the first guiding block 82 and the second guiding block 83 to slide towards the middle and close together or slide apart towards both sides to adjust the distance between the first guiding block 82 and the second guiding block 83.

[0162] When the lifting driving mechanism 3 drives the lifting bracket 4 to descend in place, the first guiding block 82 and the second guiding block 83 are tightly attached to the two side edges of the battery cell module 100. When the pressing mechanism pushes the first steel belt 201 or the second steel belt 202 downward, the first guiding block 82 and the second guiding block 83 support and guide the two second side edges of the first steel belt 201 or the second steel belt 202 from the inside, so that the first steel belt 201 or the second steel belt 202 is sleeved onto the battery cell module 100.

[0163] The optional working process of the first guiding component 8 is as follows:

[0164] In the initial state, the lifting bracket 4 is at the initial high position far from the battery cell module 100, and the first guiding block 82 and the second guiding block 83 move closer to the middle, thereby avoiding the first steel belt 201 or the second steel belt 202.

[0165] Then, the distance adjustment driving member 81 drives the first guiding block 82 and the second guiding block 83 to slide apart towards both sides, so that the distance between the first guiding block 82 and the second guiding block 83 is adapted to the width of the battery cell module 100.

[0166] Subsequently, the lifting driving mechanism 3 drives the lifting bracket 4 to descend in place, so that the first guiding block 82 and the second guiding block 83 are tightly attached to the two side edges of the battery cell module 100. In this way, when the pressing mechanism pushes the first steel belt 201 or the second steel belt 202 downward, the first guiding block 82 and the second guiding block 83 guide the two second side edges of the first steel belt 201 or the second steel belt 202 from the inside, and finally the first steel belt 201 or the second steel belt 202 is sleeved onto the battery cell module 100.

[0167] The distance adjustment driving member 81 can, for example, be a clamping cylinder with two driving ends. The first guiding block 82 and the second guiding block 83 are oppositely installed on the two driving ends of the clamping cylinder. The clamping cylinder drives the first guiding block 82 and the second guiding block 83 to slide closer to each other in the middle or slide apart to both sides by controlling the clamping or opening of its two driving ends. Of course, the distance adjustment driving member 81 can also be two driving cylinders with opposite driving directions, and the driving ends of the two cylinders are respectively connected to the first guiding block 82 and the second guiding block 83, so as to implement the reverse driving of the first guiding block 82 and the second guiding block 83.

[0168] As Figure 8 shown, optionally, clamping grooves are provided on the inner sides of both the first guiding block 82 and the second guiding block 83, and guiding surfaces extending in the vertical direction are formed on the outer sides of the first guiding block 82 and the second guiding block 83. When the lifting driving mechanism 3 drives the lifting bracket 4 to descend in place, the first guiding block 82 and the second guiding block 83 are respectively clamped to the two side edges of the battery cell module 100 through the clamping grooves on their inner sides. When the pressing mechanism pushes down the first steel strip 201 or the second steel strip 202, the first guiding block 82 and the second guiding block 83 respectively implement the downward guiding of the two second side edges of the first steel strip 201 or the second steel strip 202 through the guiding surfaces on their outer sides.

[0169] As Figures 3 to 4 shown, optionally, the battery cell module steel strip sleeving device in the embodiment of the present application further includes a second guiding mechanism arranged on the lifting bracket 4. When the pressing mechanism pushes down the first steel strip 201 or the second steel strip 202, the second guiding mechanism is configured to support and guide two opposite first side edges of the first steel strip 201 or the second steel strip 202 from the inside, so that the first steel strip 201 or the second steel strip 202 slides downward to the first installation position or the second installation position under the guidance of the second guiding mechanism. The first side edge is generally the short side of the steel strip.

[0170] By arranging the second guiding mechanism, when the pressing mechanism pushes down the first steel strip 201 or the second steel strip 202, the second guiding mechanism supports and guides two opposite first side edges of the first steel strip 201 or the second steel strip 202 from the inside, so that the first steel strip 201 or the second steel strip 202 slides downward to the corresponding installation position under the guidance of the second guiding mechanism, preventing the first steel strip 201 or the second steel strip 202 from getting stuck and tilting in position during the downward sliding process.

[0171] Optionally, the second guiding mechanism includes two second guiding components 9 disposed at both ends of the lifting bracket 4. The two second guiding components 9 cooperate to support and guide two first sides of the first steel belt 201 or the second steel belt 202 from both ends. The second guiding component 9 includes a sixth driving member 91 and a guiding plate 92. The sixth driving member 91 is disposed on the lifting bracket 3, and the guiding plate 92 is connected to the driving end of the sixth driving member 91. The sixth driving member 91 is configured to drive the guiding plate 92 to descend, so that the guiding plate 92 abuts against the end face of the battery cell module 100.

[0172] Before the pressing mechanism presses down the first steel belt 201 or the second steel belt 202, the sixth driving member 91 drives the guiding plate 92 to descend, so that after the guiding plate 92 passes through the first steel belt 201 or the second steel belt 202, it abuts against the end face of the battery cell module 100 and descends until the lower end of the guiding plate 92 approaches the first installation position or the second installation position. Thus, when the pressing mechanism presses down the first steel belt 201 or the second steel belt 202, the two first sides of the first steel belt 201 or the second steel belt 202 slide downward under the guidance of the guiding plate 92 at the two end faces of the battery cell module 100 until reaching the first installation position or the second installation position.

[0173] The sixth driving member 91 may adopt various existing linear driving modules capable of driving the guiding plate 92 to lift and lower, such as air cylinders, screw motors, etc.

[0174] Optionally, the guiding plate 92 is located between the two buffer plates 52. Thus, the guiding plate 92 can freely lift and lower under the drive of the sixth driving member 91 without interference with the buffer plates 52.

[0175] As Figure 3 shown, optionally, the battery cell module steel belt sleeving device in the embodiment of the present application further includes a pressing plate 10 disposed at the bottom of the lifting bracket 4. When the lifting driving mechanism 3 drives the lifting bracket 4 to descend in place, 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 belt sleeving process. Optionally, a plurality of pressing plates 10 are provided, and the plurality of pressing plates 10 are arranged at intervals 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 100 from different positions to enhance the downward pressing effect on the battery cell module 100.

Those of ordinary skill in the art should understand that the description in the embodiments is only exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the protection scope of the present application.
