Description

Technical Field

[0001] This application belongs to the field of battery module PACK production technology, and more specifically, relates to a battery module stacking equipment. Background Technology

[0002] Due to the rapid development of the new energy vehicle industry, the demand for power batteries is increasing day by day. The traditional single-row module stacking and manual stacking methods can no longer meet the production compatibility requirements. A new technology is needed to improve the efficiency of battery module stacking. Utility Model Content

[0003] This application provides a battery module stacking device that can improve battery module stacking efficiency.

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

[0005] Base;

[0006] A rotating body is rotatably mounted on the base, and mounting inclined surfaces are provided on both sides of the rotating body; and

[0007] Two stacking modules are respectively disposed on the two mounting slopes. Each stacking module includes multiple stacking shaping devices, and each stacking shaping device is sequentially disposed on the mounting slope along a first direction.

[0008] The stacking and shaping device includes:

[0009] A base plate is provided on the mounting slope, and the upper end of the base plate is a material receiving position;

[0010] An end block is located at the lower end of the base plate;

[0011] The stacking receiving mechanism includes two receiving blocks, which are located on both sides of the receiving position along the first direction. The two receiving blocks can move closer to or further away from each other. When the two receiving blocks are close together, they can receive the battery.

[0012] The gripper mechanism is movable along the length direction of the base plate, and the gripper mechanism can clamp or release the battery. The length direction forms an angle with the first direction.

[0013] A height-shaping mechanism includes a movable support and a pressing component. The movable support is movable along the length of the base plate, and the pressing component is disposed on the movable support and can be close to or away from the base plate.

[0014] A clamping mechanism is provided at the receiving position, and the clamping mechanism can move toward the end block to clamp the multiple batteries between the end block and the clamping mechanism.

[0015] Furthermore, the two ends of the base plate are connected to the mounting inclined surface by support blocks, and a gap is formed between the base plate and the mounting inclined surface.

[0016] Furthermore, the stacking receiving mechanism also includes a first guide rail, two first sliders, two receiving rods, and a first driving assembly. The first guide rail is disposed along the first direction on the mounting inclined surface and located within the gap. The two first sliders are slidably disposed on the first guide rail. One end of each receiving rod is connected to a corresponding first slider, and a receiving block is disposed at the other end of the corresponding receiving rod. The first driving assembly drives the two sliders to move closer or further apart. When the two sliders move closer, the distance between the two receiving blocks is less than the width of the battery along the first direction. When the two sliders move further apart, a gripper mechanism holding the battery can pass between the two receiving blocks.

[0017] Furthermore, the stacking receiving mechanism also includes two first adjusting rods, each of which is disposed on a corresponding first slider. The length direction of the first adjusting rod is set along the first direction, and the end of the receiving rod away from the receiving block is adjustablely disposed on the first adjusting rod along the first direction.

[0018] Furthermore, the first driving component includes a first driver and a second driver, the first driver being connected to one of the sliders, the second driver being connected to the other slider, and the first driver and the second driver having opposite driving directions;

[0019] In two adjacent stacking shaping devices, a set of the first driving components is shared.

[0020] Furthermore, the gripper mechanism includes:

[0021] A movable plate is provided in the gap and can move along the length of the base plate;

[0022] A third driver is located on the movable plate;

[0023] Two grippers are located on both sides of the base plate and are arranged opposite to each other. The two grippers are connected to the third driver and are driven by the third driver to move closer to or further away from each other.

[0024] Furthermore, the gripper mechanism also includes two second adjusting rods, one end of which is connected to the third driver. The length direction of the second adjusting rod is set along the first direction, and the other end of the gripper is adjustablely set on the second adjusting rod along the first direction.

[0025] Furthermore, the height shaping mechanism also includes a telescopic driver and a mounting plate. The telescopic driver is disposed on the movable bracket and can extend and retract along the length of the base plate. The mounting plate is connected to the telescopic end of the telescopic driver. The pressing assembly includes two fourth drivers and two pressing members. The fourth drivers are disposed on the mounting plate, and the pressing members are connected to the corresponding fourth drivers. The position of the pressing members corresponds to the position of the battery terminals and faces the base plate. The fourth drivers are used to drive the pressing members to move closer to or away from the base plate.

[0026] Furthermore, the clamping mechanism includes a pressure block and a fifth driver. The pressure block is located at the receiving position, and the fifth driver is used to drive the pressure block closer to or further away from the end block.

[0027] Furthermore, the stacking module also includes a lead screw drive mechanism, which includes a sixth driver, a lead screw, a nut, and a connecting plate. The lead screw is rotatably disposed on the mounting inclined surface along the length direction of the base plate, and the nut is slidably disposed on the mounting inclined surface along the length direction of the base plate. The nut is fitted onto the lead screw. The sixth driver is used to drive the lead screw to rotate. The connecting plate is connected to the nut. Each of the gripper mechanisms and moving brackets in the stacking module is connected to the connecting plate.

[0028] The beneficial effects of the battery module stacking device provided in this application are as follows:

[0029] 1. In the battery module stacking equipment provided in this application embodiment, a rotatable connection structure between the base and the rotating body is used. Mounting ramps are respectively provided on both sides of the rotating body, and stacking modules are configured on each mounting ramp. This structural combination allows the equipment to receive batteries for stacking on one side (e.g., side A) and unload them on the other side (e.g., side B), and quickly switch between the two working modes by rotating the rotating body. This design avoids the limitation of a single working mode in traditional stacking methods, significantly improving the equipment's working efficiency and enabling the stacking and unloading of more battery modules in a shorter time.

[0030] 2. When the stacking robot places batteries, the two receiving blocks are close together to stably support the batteries. After the batteries are placed, the two receiving blocks move away from each other to make room for the gripper mechanism to pick up the batteries and move downwards. The gripper mechanism can move along the length of the base plate. After the stacking receiving mechanism receives the battery, the gripper mechanism clamps the battery and accurately brings it to the end block, achieving orderly stacking of the batteries and ensuring the positional accuracy of the batteries during the stacking process. After the gripper mechanism brings the battery to the end block, the moving bracket drives the pressing component to the bottom. The pressing component presses the battery onto the base plate for height shaping, ensuring the height consistency of each battery during the stacking process and improving the overall quality of the battery module. Then, the above process is repeated for subsequent battery stacking. The clamping mechanism is located at the receiving position and can move towards the end block to clamp multiple batteries between the end block and the clamping mechanism. After multiple batteries are stacked in sequence, the function of the clamping mechanism is to firmly fix the batteries together to form a stable module structure. This structure and connection relationship ensure the stability and integrity of the battery module after stacking, improving product quality. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0052] Please see Figure 1 The battery module stacking device provided in the embodiments of this application will now be described.

[0053] Reference Figure 1 The battery module stacking device provided in this application includes a base 10, a rotating body 20, and two stacking modules 30.

[0054] Reference Figure 1 and Figure 2 The base 10 is the fundamental support component of the entire equipment, serving to support and secure other parts. The base 10 can be a structural component with sufficient strength and stability, such as a rectangular metal frame or a thick steel plate. The size and shape of the base 10 are determined based on the overall design of the equipment and space requirements, ensuring that the equipment can be stably placed on the ground during operation without shaking or tipping over.

[0055] Reference Figure 1 and Figure 2 The rotating body 20 is rotatably mounted on the base 10, and each of the two sides of the rotating body 20 is provided with an mounting inclined surface 21.

[0056] The rotating body 20 is a rotatable component mounted on the base 10. It is connected to the base 10 via a rotating mechanism such as bearings and can rotate around a fixed axis. The rotating body 20 has mounting ramps 21 on both sides for mounting the stacked modules 30. For example, the rotating body 20 has a triangular frame structure, its side profile resembling an isosceles triangle, with its two sides (i.e., the mounting ramps 21) symmetrically distributed. This design facilitates simultaneous stacking of batteries 40 from both sides, improving work efficiency.

[0057] Specifically, refer to Figure 2 The rotating body 20 can be driven by a motor to rotate relative to the base 10, rotating 180° at a time. A retractable pin is provided on the base 10 at the bottom plate 311 of the rotating body 20. When the rotating body 20 has rotated 180° to its final position, the pin extends and inserts into a pin hole at the bottom of the rotating body 20 to achieve positioning. When switching is required, the pin retracts, and the motor drives the rotating body 20 to rotate 180° again. A photoelectric sensor can be set to detect whether the rotating body 20 has rotated to its final position.

[0058] Reference Figure 1 Two stacking modules 30 are respectively disposed on the two mounting slopes 21. Each stacking module 30 includes a plurality of stacking shaping devices 31, and each stacking shaping device 31 is sequentially disposed on the mounting slope 21 along the first direction X.

[0059] The stacking module 30 is a component installed on the mounting ramps 21 on both sides of the rotating body 20, and each mounting ramp 21 has a stacking module 30.

[0060] Reference Figure 1 and Figure 3 Each stacking module 30 includes multiple stacking shaping devices 31, such as two, three, four, or more. In this embodiment, each stacking module 30 is described as including four stacking shaping devices 31. These stacking shaping devices 31 are arranged sequentially along a first direction X of the mounting ramp 21. The first direction X can be the direction of action, that is, the stacking shaping devices 31 are arranged from one end of the rotating body 20 to the other end.

[0061] Among them, reference Figure 3 and Figure 4 The stacking and shaping device 31 includes a base plate 311, an end block 312, a stacking receiving mechanism 313, a gripper mechanism 314, a height shaping mechanism 315, and a pressing mechanism 316.

[0062] Reference Figure 5A base plate 311 is disposed on the mounting slope 21, and the upper end of the base plate 311 is a receiving position 3111. The base plate 311 is a plate-like structure mounted on the mounting slope 21, and it is understood that the base plate 311 is also inclined. The upper end of the base plate 311 is the receiving position 3111, which is used to receive the battery 40. After the module battery stacking robot picks up the battery 40 from the pre-stacking platform, it will transport it to the receiving position 3111. Since the batteries 40 need to be stacked on the base plate 311, an insulating pad is fixedly disposed on the base plate 311 to prevent short circuits of the battery 40 output wires.

[0063] Reference Figure 6 An end block 312 is located at the lower end of the base plate 311. The function of the end block 312 is to support and position the lower end of the batteries 40 during the stacking process, much like the bottom block in a stack of building blocks, providing a stable foundation for the blocks above. The end block 312 can be a block made of rigid plastic or metal, or multiple cuboid structures arranged side-by-side to jointly support the batteries 40.

[0064] Reference Figure 4 and Figure 7 The stacking receiving mechanism 313 includes two receiving blocks 3131, which are located on both sides of the receiving position 3111 along the first direction X. The two receiving blocks 3131 can move closer to each other or further apart. When the two receiving blocks 3131 are close together, they can receive the battery 40. The receiving blocks 3131 can be two movable trays, driven by a cylinder or motor, so that the receiving blocks 3131 can be adjusted according to the size of the battery 40, thereby accurately supporting the battery 40 transported from the pre-stacking platform by the module battery stacking robot. That is, the module battery stacking robot places the battery 40 on the two receiving blocks 3131 after they are close together. After the battery 40 is placed, the two receiving blocks 3131 move further apart to make room for the gripper mechanism 314 to grip the battery 40 and move downward.

[0065] Reference Figure 4 and Figure 8 The gripper mechanism 314 can move along the length direction of the base plate 311. The gripper mechanism 314 can clamp or release the battery 40, and the length direction forms an angle with the first direction. Specifically, the gripper mechanism 314 can be a slider with a pneumatic gripper 3142, which is mounted on a guide rail and moves along the guide rail. The gripper mechanism 314 cooperates with the stacking receiving mechanism 313 and the end top block 312. After the stacking receiving mechanism 313 receives the battery 40, the gripper mechanism 314 clamps the battery 40 and accurately brings it to the end top block 312, realizing the orderly stacking of the batteries 40. The length direction of the base plate 311 can be perpendicular to the first direction X.

[0066] Reference Figure 4 and Figure 9The height shaping mechanism 315 includes a movable support 3151 and a pressing component 3152. The movable support 3151 can move along the length of the base plate 311, and the pressing component 3152 is disposed on the movable support 3151 and can be close to or away from the base plate 311.

[0067] The movable support 3151 can be a movable support structure, and the pressing component 3152 is a pressure head with a pressure sensor. During the battery stacking process, after the gripper mechanism 314 brings the battery 40 to the end block 312, the movable support 3151 drives the pressing component 3152 to move above the battery 40. The pressing component 3152 then presses down to press the battery 40 onto the base plate 311 for height shaping. This structural cooperation ensures the height consistency of each battery 40 during the stacking process, improves the overall quality of the battery module, and avoids module performance problems caused by inconsistent battery heights.

[0068] A height-adjustable clamping block 3121 may also be provided above the end block 312. The clamping block 3121 is raised and lowered by the seventh actuator 3122. After the first battery 40 is height-shaped by the pressing component 3152, the clamping block 3121 can descend to press the first battery 40, fixing the first battery 40 and preventing the position of the first battery 40 from changing in subsequent processes, which would affect the quality of the battery module. The seventh actuator 3122 may be a cylinder.

[0069] Reference Figure 4 and Figure 10 The clamping mechanism 316 is located at the receiving position 3111. The clamping mechanism 316 can approach the end block 312 to clamp the multiple batteries 40 between the end block 312 and the clamping mechanism 316.

[0070] After multiple batteries 40 are stacked sequentially, the clamping mechanism 316 secures the batteries 40 together tightly, forming a stable module structure. This structure and connection ensure the stability and integrity of the battery module after stacking, improving product quality.

[0071] The pressing mechanism 316 may include a pressure plate driven by a cylinder. When the batteries 40 are stacked to a certain number, the pressure plate presses the batteries 40 downward under the action of a spring, so that the batteries 40 are tightly fitted together, preventing the batteries 40 from loosening or shifting in subsequent processes.

[0072] The operation process of the battery module stacking device in this embodiment is as follows:

[0073] 1. After the equipment is started, the rotating body 20 is in the initial position, and the two stacking modules 30 are in different working preparation states. Assume that one side of the mounting slope 21 (A side) is in the stacking state, and the other side (B side) is in the unloading state. The two receiving blocks 3131 of the stacking receiving mechanism 313 are in a close state, located on both sides of the receiving position 3111 of the base plate 311; the gripper mechanism 314 and the height shaping mechanism 315 are located at the receiving position 3111 of the base plate 311 and are higher than the receiving blocks 3131; the clamping mechanism 316 is in the initial position and no pressure is applied to the battery 40.

[0074] 2. The stacking robot places the battery 40 to be stacked on the receiving position 3111 of the bottom plate 311 on side A. At this time, the two receiving blocks 3131 of the stacking receiving mechanism 313 move closer to each other and steadily support the battery 40. After placing the battery 40, the stacking robot leaves to pick up another battery 40.

[0075] 3. The gripper mechanism 314 moves to the receiving position 3111 and clamps the battery 40. Subsequently, the two receiving blocks 3131 of the stacked receiving mechanism 313 move away from each other, making room for the gripper mechanism 314 to move downward. The gripper mechanism 314 clamps the battery 40 and moves downward along the length of the base plate 311 until the battery 40 abuts the end top block 312.

[0076] 4. As the gripper mechanism 314 brings the battery 40 to the end block 312, the moving bracket 3151 of the height shaping mechanism 315 moves the pressing assembly 3152 along the length of the base plate 311 to a lower position. The pressing assembly 3152 approaches the base plate 311 and presses the battery 40 onto the base plate 311, shaping the height of the battery 40 to ensure that the height of the battery 40 meets the requirements. After shaping, the height shaping mechanism 315 and the gripper mechanism 314 release the battery 40 and return to the receiving position 3111, ready for the stacking operation of the next battery 40.

[0077] 5. Repeat the above steps of feeding, transferring and shaping the battery 40, and stack multiple batteries 40 on the end top block 312 in sequence until the required number of battery modules is reached, thus completing the initial stacking of a battery module.

[0078] 6. After the battery modules are initially stacked, the clamping mechanism 316 located at the receiving position 3111 moves closer to the end top block 312, clamping the multiple batteries 40 between the end top block 312 and the clamping mechanism 316, so that the battery modules form a tight whole, ensuring the stability and reliability of the modules.

[0079] 7. After the stacking and pressing of a battery module is completed on side A, the rotating body 20 rotates 180° around the base 10, so that side A switches to the unloading position and side B switches to the stacking position. At this time, side A begins the unloading operation, and side B repeats the battery 40 stacking process of side A.

[0080] 8. After rotating surface A to the unloading position, the compressed battery module is removed from the base plate 311 by external handling equipment (such as a robotic arm) to complete the unloading operation.

[0081] 9. The equipment continuously repeats the above working process, and realizes the alternating stacking and unloading operation of the stacking modules 30 on both sides by rotating the main body 20, thereby improving the stacking efficiency of the battery modules and meeting the needs of large-scale production.

[0082] Reference Figure 5 The two ends of the base plate 311 are connected to the mounting inclined surface 21 by support blocks 3112, and a gap 3113 is formed between the base plate 311 and the mounting inclined surface 21.

[0083] The support block 3112 is a component that serves a supporting and connecting function, and can be made of metal or a plastic with high hardness. The support block 3112 connects the base plate 311 and the mounting ramp 21 together, making the base plate 311 act like a bridge. Since the base plate 311 is connected to the mounting ramp 21 through the support block 3112, and the support block 3112 itself has a certain thickness, the base plate 311 and the mounting ramp 21 cannot be completely fitted together, thus creating a gap 3113.

[0084] The gripper mechanism 314 and the height shaping mechanism 315 are key components in the battery module stacking equipment, and they need to move during operation. The moving supports 3151 of both the gripper mechanism 314 and the height shaping mechanism 315 need to move along the length of the base plate 311 to perform the operations of clamping the battery 40, transferring the battery 40, and height shaping. The moving structures of these mechanisms (such as sliders and guide rails) require a certain amount of space to operate, and the gap 3113 between the base plate 311 and the mounting ramp 21 provides just such space. Without this gap 3113, the moving structures of the gripper mechanism 314 and the height shaping mechanism 315 would be obstructed during movement, potentially colliding with the mounting ramp 21, leading to equipment damage or malfunction.

[0085] Reference Figure 7The stacking receiving mechanism 313 further includes a first guide rail 3132, two first sliders 3133, two receiving rods 3134, and a first driving assembly 3135. The first guide rail 3132 is disposed along the first direction X on the mounting inclined surface 21 and located within the gap 3113. The two first sliders 3133 are slidably disposed on the first guide rail 3132. One end of each receiving rod 3134 is connected to the corresponding first slider 3133, and the receiving block 3131 is disposed at the other end of the corresponding receiving rod 3134. The first driving assembly 3135 drives the two sliders to move closer or further away from each other. When the two sliders move closer, the distance between the two receiving blocks 3131 is less than the width of the battery 40 along the first direction X. When the two sliders move further away, the gripper mechanism 314 holding the battery 40 can pass through the space between the two receiving blocks 3131.

[0086] The first guide rail 3132 is disposed on the mounting inclined surface 21 along the first direction X, and is located within the gap 3113 formed by the base plate 311 and the mounting inclined surface 21. The function of the first guide rail 3132 is to provide a precise movement path for the slider, ensuring that the slider can slide smoothly along the predetermined direction.

[0087] Two first sliders 3133 are slidably mounted on the first guide rail 3132 to achieve smooth sliding. The function of the first sliders 3133 is to support the receiving rod 3134 and move along the guide rail under the action of the first drive assembly 3135.

[0088] The receiving rod 3134 serves to connect the slider and the receiving block 3131, transmitting the movement of the slider to the receiving block 3131. The receiving rod 3134 can be made of a material with good rigidity to ensure that it will not bend or deform during movement, ensuring that the receiving block 3131 can move accurately to the designated position.

[0089] The first drive assembly 3135 is used to drive the two sliders to move closer or further apart on the guide rail. The first drive assembly 3135 can be an electric actuator, a cylinder, or a motor and lead screw 322 transmission mechanism, etc.

[0090] When the stacking robot places the battery 40 in the receiving position 3111 of the base plate 311, the first drive assembly 3135 drives two sliders to move closer together on the first guide rail 3132. As the sliders move closer, the receiving rod 3134 connected to the sliders also drives the receiving blocks 3131 to move closer together. At this time, the distance between the two receiving blocks 3131 is less than the width of the battery 40 along the first direction X, thus ensuring that the battery 40 is stably supported. This design ensures the stable placement of the battery 40 in the receiving position 3111, preparing it for subsequent stacking operations.

[0091] After the gripper mechanism 314 moves to the receiving position 3111 and clamps the battery 40, the first drive assembly 3135 drives the two sliders to move away from each other on the first guide rail 3132. As the sliders move away, the receiving rod 3134 drives the receiving blocks 3131 to also move away from each other, so that a sufficiently wide channel is formed between the two receiving blocks 3131, allowing the gripper mechanism 314 holding the battery 40 to pass through. In this way, the gripper mechanism 314 can smoothly hold the battery 40 and move downward along the base plate 311 for subsequent stacking steps.

[0092] Reference Figure 7 The stacking receiving mechanism 313 further includes two first adjusting rods 3136. The first adjusting rods 3136 are disposed on the corresponding first sliders 3133. The length direction of the first adjusting rods 3136 is arranged along the first direction X. The end of the receiving rod 3134 away from the receiving block 3131 is adjustablely disposed on the first adjusting rods 3136 along the first direction X.

[0093] In some embodiments, the stacking receiving mechanism 313 is provided with two first adjusting rods 3136, each corresponding to a first slider 3133. The first adjusting rods 3136 are mounted on the first sliders 3133, and their length direction is along the first direction X. The first adjusting rods 3136 can provide an adjustable mounting base for the receiving rods 3134.

[0094] The end of the receiving rod 3134 furthest from the receiving block 3131 is adjustablely mounted on the first adjusting rod 3136 along the first direction X, meaning the position of the receiving rod 3134 can be adjusted on the first adjusting rod 3136. For example, a bolted connection can be used. The first adjusting rod 3136 has a row of mounting holes distributed along the first direction X. The receiving rod 3134 is fixed to the first adjusting rod 3136 by bolts passing through suitable mounting holes. When it is necessary to adjust the position of the receiving rod 3134, simply loosen the bolts, move the receiving rod 3134 to the appropriate position, and then tighten the bolts again.

[0095] In the battery module production process, batteries 40 of different sizes and specifications are used. By adjusting the position of the receiving rod 3134 on the first adjusting rod 3136, the initial distance between the two receiving blocks 3131 can be changed. For larger batteries 40, the receiving rod 3134 can be adjusted away from each other, increasing the distance between the two receiving blocks 3131, thus enabling it to support larger batteries 40; while for smaller batteries 40, the receiving rod 3134 can be adjusted closer to each other, reducing the distance between the two receiving blocks 3131, to meet the needs of supporting smaller batteries 40.

[0096] Reference Figure 7The first driving component 3135 includes a first driver 31351 and a second driver 31352. The first driver 31351 is connected to one of the sliders, and the second driver 31352 is connected to the other slider. The driving directions of the first driver 31351 and the second driver 31352 are opposite. Two adjacent stacking shaping devices 31 share a set of the first driving component 3135.

[0097] Both the first actuator 31351 and the second actuator 31352 can be devices capable of outputting linear motion, such as electric actuators or cylinders. The driving directions of the first actuator 31351 and the second actuator 31352 are opposite. That is, if the first actuator 31351 pushes one slider to the left, then the second actuator 31352 will push the other slider to the right, thereby realizing the movement of the two sliders moving closer or further apart, which meets the requirements of receiving the battery 40 and making way for the gripper mechanism 314.

[0098] In two adjacent stacking and shaping devices 31, the same set of first drive components 3135 is used. For example, in a stacking receiving mechanism 313, the two sliders are slider A and slider B. When sharing a set of first drive components 3135, the first driver 31351 is connected to both sliders A, and the second driver 31352 is connected to both sliders B. Specifically, both sliders A can be connected to the first driver 31351 via a connecting rod, and both sliders B can be connected to the second driver 31352 via another connecting rod.

[0099] By sharing a set of first drive components 3135, the number of drivers used is reduced, avoiding the need to equip each stacking shaping device 31 with a separate set of drive components, thereby reducing the manufacturing cost of the equipment. Furthermore, since adjacent stacking shaping devices 31 share a set of drive components, the synchronicity of the movement of the receiving blocks 3131 in the two stacking shaping devices 31 can be better guaranteed, improving the stability and consistency of the battery 40 stacking process.

[0100] Reference Figure 8 The gripper mechanism 314 includes a movable plate, a third driver 3141, and two grippers 3142.

[0101] A movable plate (not shown in the figure) is located in the gap 3113 and can move along the length of the base plate 311. The gap 3113 provides space for the movable plate to move, ensuring that its movement is not interfered with by other components. The movable plate is the mounting base for other components of the gripper mechanism 314. The movement of the movable plate can be achieved by means of motor and lead screw 322 transmission, cylinder drive, etc. For example, a motor is used to drive the lead screw 322 to rotate, and the nut 323 on the lead screw 322 is connected to the movable plate. The rotational motion of the lead screw 322 is converted into linear motion of the nut 323 and the movable plate, thereby causing the movable plate to move along the length of the base plate 311.

[0102] The third actuator 3141 is located on the movable plate. The main function of the third actuator is to provide power for the movement of the gripper 3142, driving the two grippers 3142 to move closer or further apart. The third actuator 3141 can be an electric push rod, a gripper 3142 cylinder, etc.

[0103] The two grippers 3142 are located on both sides of the base plate 311 and are arranged opposite each other. This positional design allows the grippers 3142 to clamp the battery 40 from both sides.

[0104] The two grippers 3142 are connected to the third actuator 3141 and are driven by the third actuator 3141 to move closer or further apart. When the third actuator 3141 is working, it will bring the two grippers 3142 closer together, thereby clamping the battery 40 located on the base plate 311; when it is necessary to release the battery 40, the third actuator 3141 will reverse its action, causing the two grippers 3142 to move further apart.

[0105] During operation, after the stacking and receiving mechanism 313 receives the battery 40, the moving plate moves along the length of the base plate 311 to the receiving position 3111 under the action of the drive device. The third drive 3141 drives the two grippers 3142 to move closer to each other until the grippers 3142 tightly clamp the battery 40. After the grippers 3142 clamp the battery 40, the moving plate continues to move downward along the length of the base plate 311, transferring the battery 40 to the end top block 312. After the battery 40 reaches the designated position, the third drive 3141 drives the two grippers 3142 to move away from each other, releasing the battery 40 and completing one battery 40 transfer operation.

[0106] Reference Figure 8 The gripper mechanism 314 further includes two second adjusting rods 3143. One end of the second adjusting rod 3143 is connected to the third driver 3141. The length direction of the second adjusting rod 3143 is set along the first direction X. The other end of the gripper 3142 is adjustablely set on the second adjusting rod 3143 along the first direction X.

[0107] The third actuator 3141 provides power to the grippers 3142, allowing them to move closer or further apart, thereby clamping and releasing the battery 40. The second adjusting rod 3143, connected to the third actuator 3141, becomes part of the power transmission structure of the gripper mechanism 314.

[0108] The other end of the gripper 3142 is adjustablely mounted on the second adjusting rod 3143 along the first direction X, meaning the gripper 3142 can be positioned on the second adjusting rod 3143. This can be achieved in various ways, such as by providing a series of mounting holes distributed along the first direction X on the second adjusting rod 3143, with the gripper 3142 secured to the second adjusting rod 3143 by bolts passing through suitable mounting holes. When the position of the gripper 3142 needs to be adjusted, simply loosen the bolts, move the gripper 3142 to the appropriate position, and then tighten the bolts again.

[0109] During the production of the battery module, the size specifications of the battery 40 may vary. By adjusting the position of the gripper 3142 on the second adjusting rod 3143, the initial distance between the two grippers 3142 can be changed to accommodate batteries 40 of different sizes. For larger batteries 40, the grippers 3142 can be adjusted away from each other to increase the distance between the two grippers 3142, thereby clamping the larger battery 40; while for smaller batteries 40, the grippers 3142 can be adjusted closer to each other to reduce the distance between the two grippers 3142, thus achieving effective clamping of the smaller battery 40.

[0110] Reference Figure 9 The height shaping mechanism 315 further includes a telescopic driver 3153 and a mounting plate 3154. The telescopic driver 3153 is disposed on the movable bracket 3151 and can extend and retract along the length of the base plate 311. The mounting plate 3154 is connected to the telescopic end of the telescopic driver 3153. The pressing assembly 3152 includes two fourth drivers 31521 and two pressing members 31522. The fourth drivers 31521 are disposed on the mounting plate 3154, and the pressing members 31522 are connected to the corresponding fourth drivers 31521. The position of the pressing member 31522 corresponds to the position of the terminal post of the battery 40 and faces the base plate 311. The fourth drivers 31521 are used to drive the pressing member 31522 to move closer to or away from the base plate 311.

[0111] During the battery module stacking process, when the stacking robot places the battery 40 onto the stacking receiving device (receiving position 3111 on the base plate 311), if the pressing component 3152 is in a low position, it may obstruct the placement of the battery 40. Because the pressing component 3152 is typically located above the base plate 311, its size and position may interfere with the path of the battery 40, preventing the battery 40 from being placed smoothly into the designated position and affecting the smoothness and efficiency of the entire stacking process.

[0112] The telescopic actuator 3153 effectively solves the above problems. The telescopic actuator 3153 is mounted on the movable bracket 3151 and can extend and retract along the length of the base plate 311. The mounting plate 3154 is connected to the telescopic end of the telescopic actuator 3153, and the pressing component 3152 is mounted on the mounting plate 3154.

[0113] When the battery 40 is ready to be placed into the stacking receiving device, the telescopic actuator 3153 is in the retracted state. At this time, the telescopic actuator 3153 drives the mounting plate 3154 and the pressing component 3152 mounted on it to move upward to a higher position, so that the pressing component 3152 is away from the receiving position 3111 of the base plate 311, leaving enough space for the battery 40 to be placed and avoiding obstruction of the battery 40 placement process by the pressing component 3152. When the battery 40 is successfully placed on the stacking receiving device, the gripper mechanism 314 clamps the battery 40 and moves it to the end top block 312, and then the telescopic actuator 3153 extends. This action will drive the mounting plate 3154 and the pressing component 3152 to move downward along the length direction of the base plate 311, so that the pressing component 3152 reaches the appropriate position for height shaping of the battery 40.

[0114] Specifically, the telescopic actuator 3153 can be an electric push rod, a cylinder, or other device that can convert electrical or pneumatic energy into mechanical energy for linear motion.

[0115] Mounting plate 3154 is connected to the telescopic end of telescopic actuator 3153. When telescopic actuator 3153 extends or retracts, mounting plate 3154 moves along with the telescopic end. Mounting plate 3154 provides a platform for mounting pressing assembly 3152, serving to support and fix pressing assembly 3152, ensuring that pressing assembly 3152 can operate stably.

[0116] The fourth actuator 31521 is mounted on the mounting plate 3154 and is mainly responsible for driving the movement of the pressing member 31522. The fourth actuator 31521 can also be an electric push rod, cylinder, or other type, and its extension and retraction are controlled to make the pressing member 31522 move closer to or away from the base plate 311.

[0117] The pressing component 31522 is connected to the corresponding fourth driver 31521, and its position corresponds to the terminal position of the battery 40, facing the base plate 311. The terminal is an important component on the battery 40 used to connect to external circuits. During the battery module stacking process, the height of the terminal needs to be precisely shaped to ensure the performance and safety of the battery module. When the pressing component 3152 is working, the fourth driver 31521 drives the pressing component 31522 to move closer to the base plate 311. The pressing component 31522 acts on the terminal of the battery 40, pressing down on the terminal, thereby achieving the purpose of shaping the height of the battery 40.

[0118] During operation, after the gripper mechanism 314 moves the battery 40 to the end block 312, the height shaping mechanism 315 begins to work. First, the telescopic actuator 3153 extends, driving the mounting plate 3154 and the pressing assembly 3152 to move downwards along the length of the base plate 311, so that the pressing member 31522 reaches the height position corresponding to the battery 40's terminal. Next, the fourth actuator 31521 drives the pressing member 31522 closer to the base plate 311, and the pressing member 31522 applies pressure to the battery 40's terminal, performing height shaping. After shaping is completed, the fourth actuator 31521 drives the pressing member 31522 away from the base plate 311, the telescopic actuator 3153 retracts, and the height shaping mechanism 315 returns to its initial position, awaiting the next shaping operation.

[0119] Reference Figure 9 The pressing mechanism 316 includes a pressing block 3161 and a fifth driver 3162. The pressing block 3161 is located at the receiving position 3111, and the fifth driver 3162 is used to drive the pressing block 3161 to move closer to or away from the end top block 312.

[0120] The fifth actuator 3162 is a component that provides power for the movement of the pressure block 3161. The fifth actuator 3162 can be of various types, commonly including electric actuators, hydraulic cylinders, or pneumatic cylinders.

[0121] The function of the fifth actuator 3162 is to drive the pressing block 3161 closer to or further away from the end top block 312. After multiple batteries 40 are stacked sequentially between the end top block 312 and the receiving position 3111, the fifth actuator 3162 is activated, outputting power to push the pressing block 3161 towards the end top block 312. As the pressing block 3161 moves, it gradually approaches and eventually contacts the topmost battery 40, then applies pressure to the entire battery module, tightly pressing the multiple batteries 40 between the end top block 312 and the pressing block 3161 together. When the battery module completes the pressing process and subsequent unloading or other operations are required, the fifth actuator 3162 reverses its action, driving the pressing block 3161 away from the end top block 312, releasing the pressure on the battery module, and creating conditions for the smooth removal of the battery module.

[0122] Reference Figure 1 and Figure 10 The stacking module 30 further includes a lead screw drive mechanism 32, which includes a sixth driver 321, a lead screw 322, a nut 323, and a connecting plate. The lead screw 322 is rotatably disposed on the mounting inclined surface 21 along the length direction of the base plate 311, and the nut 323 is slidably disposed on the mounting inclined surface 21 along the length direction of the base plate 311. The nut 323 is fitted onto the lead screw 322. The sixth driver 321 is used to drive the lead screw 322 to rotate. The connecting plate connects the nut 323. Each of the gripper mechanisms 314 and the moving bracket 3151 in the stacking module 30 is connected to the connecting plate.

[0123] The sixth actuator 321 is the power source for the lead screw drive mechanism 32, and can typically be an electric motor, such as a stepper motor or a servo motor. These motors can precisely control the rotation of the lead screw 322 to achieve precise control over the movement of the gripper mechanism 314 and the height shaping mechanism 315.

[0124] The lead screw 322 can be a metal rod with high-precision threads, which is mounted on the mounting slope 21 by bearings and other components to ensure that it can rotate smoothly.

[0125] When the lead screw 322 rotates, due to the threaded engagement between the lead screw 322 and the nut 323, the nut 323 will move linearly along the lead screw 322. The material of the nut 323 usually also has good wear resistance and strength to ensure its stability during long-term use.

[0126] The connecting plate serves as a connection and transmission mechanism. When the nut 323 moves linearly under the drive of the lead screw 322, the connecting plate will also move accordingly.

[0127] The moving brackets 3151 of each gripper mechanism 314 and height shaping mechanism 315 in the stacking module 30 are all connected to the connecting plate. This means that when the lead screw drive mechanism 32 is working, the sixth driver 321 drives the lead screw 322 to rotate, and the lead screw 322 drives the nut 323 to move along the length direction of the base plate 311. The movement of the nut 323 is transmitted to the gripper mechanism 314 and the moving bracket 3151 through the connecting plate, so that the gripper mechanism 314 and the height shaping mechanism 315 can move synchronously along the length direction of the base plate 311.

[0128] The screw drive mechanism 32 ensures that the moving supports 3151 of each gripper mechanism 314 and height shaping mechanism 315 in the stacking module 30 operate synchronously. During the battery module stacking process, the gripper mechanism 314 needs to transport the battery 40 from the receiving position 3111 to the end block 312, and the height shaping mechanism 315 needs to perform height shaping on the battery 40 at the appropriate time. The screw drive mechanism 32 ensures that these two actions are coordinated and consistent, improving stacking efficiency and accuracy.

[0129] Because the lead screw 322 transmission has high precision, the sixth driver 321 can precisely control the number of rotations and angle of the lead screw 322, thereby precisely controlling the movement distance of the nut 323 and the connecting plate. This allows the gripper mechanism 314 and the height shaping mechanism 315 to accurately reach the predetermined positions, meeting the stacking requirements of battery modules of different specifications.

[0130] Multiple gripper mechanisms 314 and moving brackets 3151 share a single lead screw drive mechanism 32, avoiding the need to set up a separate drive device for each component, simplifying the overall structure of the stacked module 30, and reducing equipment costs and maintenance difficulty.

[0131] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
