Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to an assembly equipment, an assembly method, and a battery production line. Background Technology

[0002] A battery consists of a cell module and an end plate located at the end of the cell module. After the end plate and the cell module are assembled, they need to meet certain tolerance requirements. However, in the battery assembly process, traditional assembly equipment does not have high assembly accuracy for the end plate and the cell module. Summary of the Invention

[0003] The main objective of this invention is to provide an assembly equipment, assembly method, and battery production line, which aims to improve the problem of low assembly accuracy between end plates and cell modules.

[0004] To achieve the above objectives, the present invention provides assembly equipment, assembly method, and battery production line. The assembly equipment includes a first positioning fixture, a second positioning fixture, a flipping drive device, and a moving drive device. The first positioning fixture is used to position the battery cell module in a first direction and a second direction. The battery cell module has two end faces opposite each other in a third direction, and any two of the first direction, the second direction, and the third direction are arranged at an angle. The second positioning fixture is located on one side of the first positioning fixture along the third direction and is used to position the end plate. The end plate has a mounting surface that mates with the end face of the battery cell module. The flipping drive device is driven by the second positioning fixture to drive the second positioning fixture to flip, and enables the second positioning fixture to have a first state and a second state. In the first state, the second positioning fixture positions the end plate in the first direction and the third direction, and the mounting surface faces the second direction. In the second state, the mounting surface of the end plate faces the third direction and is aligned with the end face of the battery cell module in the first direction and the second direction. The moving drive device is driven by the second positioning fixture and drives the second positioning fixture to move along the third direction when the second positioning fixture is in the second state.

[0005] The technical solution of the present invention sets up a first positioning fixture, which can position the battery cell module in a first direction and a second direction. The second positioning fixture is set on one side of the first positioning fixture along a third direction, and is used to position the end plate in the first direction and the third direction in a first state. This allows the second positioning fixture to be in a state facing the second direction, which facilitates the positioning of the end plate onto the second positioning fixture and reduces the risk of interference between the first positioning fixture and the end plate positioning.

[0006] By connecting the flipping drive device to the second positioning fixture, the second positioning fixture is flipped to the second state, so that the assembly surface of the end plate faces the third direction and is aligned with the end face of the battery cell module in the first and second directions. The moving drive device is connected to the second positioning fixture and drives the second positioning fixture to move along the third direction when the second positioning fixture is in the second state. Thus, the end plate positioned on the second positioning fixture can achieve a precise assembly effect with the battery cell module simply by flipping and translating. In this assembly process, the positioning, flipping, and assembly processes of the end plate with the end face of the battery cell module are all performed on the second positioning fixture without the need to switch to other platforms. This further improves the assembly accuracy and efficiency of the end plate and the battery cell module, simplifies the structure of the assembly equipment, and reduces the size of the assembly equipment.

[0007] In one embodiment, the first positioning fixture includes a lateral clamping mechanism and a lifting mechanism. There are two lateral clamping mechanisms, which are arranged opposite to each other in the first direction and respectively abut against the opposite sides of the battery cell module. The lifting mechanism limits the position of the battery cell module in the second direction.

[0008] This configuration, with two symmetrically positioned lateral clamping mechanisms, enables centering of the battery cell module in the first direction, improving its positioning accuracy and consequently enhancing the assembly precision between the end plate and the cell module's end face. A lifting mechanism drives the cell module to move in the second direction, facilitating vertical adjustment of its position. This allows the cell module to move to a height aligned with the flipped end plate, achieving precise fit between the end plate and the cell module's end face.

[0009] Furthermore, with this configuration, when the end plate is limited in the first and third directions by the second positioning fixture, the end plate is in a horizontal state. This facilitates the transfer of the end plate from its loading position to the second positioning fixture using a gripping device such as a robotic arm. During end plate positioning, there is no interference from the battery cell module or the first positioning fixture, thus improving positioning efficiency and accuracy. Moreover, when the end plate is placed horizontally on the second positioning fixture, the placement platform of the second positioning fixture provides good support for the bottom of the end plate, reducing the risk of tilting after positioning.

[0010] In one embodiment, the lateral clamping mechanism includes a driving member and a clamping member. The driving member is throttledly connected to the clamping member and drives the clamping member to move in the first direction. The clamping member includes a base plate and a side plate connected to the base plate. The side plate abuts against the battery cell module in the first direction, and the base plate supports the battery cell module in the second direction.

[0011] This configuration achieves the effect of positioning the battery cell module from both the side and the bottom. It also allows the lifting mechanism to drive the battery cell module and the side clamping mechanism to rise and fall together, ensuring that the battery cell module has a stable posture during the lifting process.

[0012] In one embodiment, the first positioning fixture further includes a pressing mechanism, which, together with the lifting mechanism, limits the relative positions of the battery cell module on both sides in the second direction.

[0013] This design reduces the risk of the battery cell module swaying on the lifting mechanism.

[0014] In one embodiment, the second positioning fixture includes a bracket, a slide, and a fixture body. The bracket is disposed on one side of the first positioning fixture along the third direction. The slide is slidably disposed on the bracket and is driven by the moving drive device. The flipping drive device is disposed on the slide. When the second positioning fixture is in a first state, the fixture body is used to position the end plate in the first direction and the third direction. The fixture body is driven by the flipping drive device, and the rotation axis of the fixture body is parallel to the first direction.

[0015] With this setup, the end plate can be positioned on the fixture body first, and then the fixture body can be rotated by the flipping drive device to achieve the effect of flipping the end plate to a vertical position. Then, by setting the flipping drive device on the slide table, which is slidably mounted on the bracket, and the moving drive device drives the slide table to move in the third direction, the end plate and the battery cell module can be precisely assembled.

[0016] In one embodiment, when the second positioning fixture is in a first state, the fixture body includes a support platform, a first limiting component, and a second limiting component. The support platform is used to support the end plate. The first limiting component is disposed on the support platform and limits the end plate in a first direction. The second limiting component is disposed on the support platform and limits the end plate in a third direction. The first limiting component, the second limiting component, and the support platform together enclose a positioning space for positioning the end plate.

[0017] This design reduces the risk of the end plate tilting after being positioned on the second positioning fixture due to the gravity of the end plate.

[0018] In one embodiment, when the second positioning fixture is in the first state, the second limiting component includes a first movable limiting member, an elastic member, a second movable limiting member, and a driving mechanism. The two ends of the elastic member are respectively connected to the first movable limiting member and the support platform, and the elastic member extends along the third direction. The second movable limiting member is disposed opposite to the first movable limiting member in the third direction and is slidably disposed on the support platform. The driving mechanism is drively connected to the second movable limiting member and drives the second movable limiting member to move closer to or away from the first movable limiting member along the third direction.

[0019] This setting allows for fine-tuning of the height of the end plate after it is flipped.

[0020] In one embodiment, when the second positioning fixture is in the first state, the first movable limiting member is disposed on the side of the second movable limiting member that is away from the first positioning fixture along the third direction.

[0021] With this configuration, after the end plate is flipped to a vertical position, the first movable limiting member is located at the bottom of the end plate, and the first movable limiting member will not undergo elastic deformation. Therefore, it can provide good support for the end plate and reduce the risk of the end plate changing position in the vertical direction.

[0022] The present invention also proposes an assembly method based on the above-mentioned assembly equipment, the assembly method comprising:

[0023] The first positioning fixture is controlled to position the battery cell module and place it in the assembly position; Control the positioning of the end plate by the second positioning fixture; The flipping drive device is activated to drive the second positioning fixture to flip, so that the mounting surface of the end plate is aligned with the end face of the battery cell module in the first direction and the second direction. The movement drive device is activated to drive the second positioning fixture to move along a third direction and assemble with the end face of the battery cell module.

[0024] The assembly method of this invention first controls the first positioning fixture to position the battery cell module and place it in the assembly position, thus ensuring the battery cell module has a stable and unchanging state. Then, by controlling the second positioning fixture to position the end plate, the end plate can be pre-positioned, reducing the risk of tilting or wobbling during subsequent movement towards the battery cell module. Next, by activating the flipping drive device and driving the second positioning fixture to flip, the assembly surface of the end plate is aligned with the end face of the battery cell module in the first and second directions. Finally, the moving drive device is activated and drives the second positioning fixture to move along a third direction. This allows the end plate, positioned on the second positioning fixture, to achieve precise assembly with the battery cell module simply through flipping and translational movements.

[0025] During this assembly process, the positioning, flipping, and assembly of the end plate with the end face of the battery cell module are all performed on the second positioning fixture. There is no need to switch to other platforms, which reduces the risk of decreased accuracy after the end plate is transferred. This further improves the assembly accuracy and efficiency of the end plate and the battery cell module, simplifies the structure of the assembly equipment, and reduces the size of the assembly equipment.

[0026] In one embodiment, the first positioning fixture includes a lateral clamping mechanism and a lifting mechanism. Two lateral clamping mechanisms are provided, arranged opposite each other in the first direction and respectively abutting against opposite sides of the battery cell module. The lifting mechanism limits the position of the battery cell module in the second direction. The step of controlling the first positioning fixture to position the battery cell module and place it in the assembly position includes: The lifting mechanism is controlled to drive the battery cell module to move along the second direction to the assembly position; The lateral clamping mechanism is controlled to clamp the opposite sides of the battery cell module along the first direction.

[0027] By driving the battery cell module to the assembly position in the second direction using a lifting mechanism, the risk of movement of the battery cell module in the second direction can be reduced, that is, the risk of movement of the battery cell module in the vertical direction can be reduced. Then, by using a lateral clamping mechanism to clamp the opposite sides of the battery cell module along the first direction, the stability of the battery cell module in the assembly position is further improved. Furthermore, the battery cell module is driven to move along the second direction by the lifting mechanism. The second direction is the vertical direction, while the first and third directions can be two directions forming an angle on the horizontal plane. Therefore, when the end plate is positioned on the second positioning fixture, the end plate is in a horizontal state. At this time, it is convenient to transfer the end plate from the loading position to the second positioning fixture by gripping devices such as robotic arms. The positioning of the end plate will not be affected by interference from the battery cell module and the first positioning fixture. Moreover, the end plate can be placed horizontally on the second positioning fixture. The placement platform of the second positioning fixture can provide good support for the bottom of the end plate. The end plate is less likely to tilt after positioning, thereby improving the positioning stability of the end plate. This provides a stable foundation for the subsequent flipping drive device to flip the end plate and the translation drive device to move the end plate, thereby improving the assembly accuracy of the end plate and the battery cell module.

[0028] In one embodiment, the first positioning fixture further includes a pressing mechanism, which, together with the lifting mechanism, limits the relative positions of the battery cell module on opposite sides in the second direction. Following the step of controlling the lateral clamping mechanism to clamp the opposite sides of the battery cell module along the first direction, the fixture further includes: The pressing mechanism is controlled to press down to abut against the battery cell module.

[0029] With this configuration, the pressing mechanism and the lifting mechanism respectively limit the battery cell module on opposite sides in the second direction, thereby reducing the risk of the battery cell module swaying on the lifting mechanism.

[0030] The present invention also proposes a battery production line, including the assembly equipment described above. Attached Figure Description

[0034] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0037] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0038] A battery consists of a cell module and an end plate located at the end of the cell module. The end plate has four notches, and the fit tolerances between these notches and their corresponding positions on the cell module end must be maintained within a certain range. Therefore, the precise positioning between the end plate and the cell module during battery assembly directly affects the assembly yield and production efficiency. Traditional assembly equipment uses a robotic gripper to pick up the end plate and cell module and place them on a stacking ramp buffer platform. The stacking ramp gripper then picks up the end plate and cell module from the buffer platform to complete the stacking assembly. However, the inconsistent positions of the end plate and cell module picked up from the buffer platform result in low assembly accuracy between the end plate and the cell module.

[0039] To address the issue of low assembly accuracy between end plates and battery cell modules in related technologies, this invention proposes an assembly device.

[0040] like Figure 1 As shown, in one embodiment of the present invention, the assembly equipment includes a first positioning fixture 100, a second positioning fixture 200, a flipping drive device 300, and a moving drive device 400. The first positioning fixture 100 is used to position the battery cell module in a first direction Y and a second direction Z. The battery cell module has two end faces opposite each other in a third direction X, and any two of the first direction Y, the second direction Z, and the third direction X are arranged at an angle. The second positioning fixture 200 is located on one side of the first positioning fixture 100 along the third direction X and is used to position the end plate. The end plate has a mounting surface for mounting the end face of the battery cell module. The flipping drive device 300 drives the second positioning fixture 200. The connection drives the second positioning fixture 200 to rotate, enabling the second positioning fixture 200 to have a first state and a second state. In the first state, the second positioning fixture 200 is used to position the end plate in the first direction Y and the third direction X, with the assembly surface facing the second direction Z. In the second state, the assembly surface of the end plate faces the third direction X and is aligned with the end face of the battery cell module in the first direction Y and the second direction Z. The movement drive device 400 is connected to the second positioning fixture 200 and drives the second positioning fixture 200 to move along the third direction X when the second positioning fixture 200 is in the second state.

[0041] The first positioning fixture 100 is used to position the battery cell module in the first direction Y and the second direction Z, thereby improving the stability of the battery cell module during assembly with the end plate. The first direction Y and the second direction Z are set at an angle. For example, when the first direction Y is the front-back direction, the second direction Z can be the up-down direction or the left-right direction. When the first direction Y is the left-right direction, the second direction Z can be the up-down direction or the front-back direction. The battery cell module has two end faces opposite each other in the third direction X, which can be assembled with the end plate. The third direction X is set at an angle to both the first direction Y and the second direction Z. For example, the first direction Y, the second direction Z, and the third direction X can be the front-back direction, the up-down direction, and the left-right direction, respectively; or the first direction Y, the second direction Z, and the third direction X can be the left-right direction, the up-down direction, and the front-back direction, etc. With this configuration, when assembling the end plate with the end face of the battery cell module, the first positioning fixture 100 can provide clearance space for the assembly process, reducing the risk of interference from the first positioning fixture 100 during the assembly process. The first positioning fixture 100 may include a first positioning platform and a first elastic limiting block disposed on the first positioning platform. At least two first elastic limiting blocks are disposed opposite each other, and these two opposing first elastic limiting blocks can limit the opposite sides of the battery cell module in the first direction Y or the second direction Z. Alternatively, the first positioning fixture 100 may include a first gripper that clamps the battery cell module in the first direction Y or the second direction Z and a first driving component for driving the first gripper closer to or further away from the battery cell module, as long as the positioning effect of the battery cell module in the first direction Y and the second direction Z can be achieved. The first positioning fixture 100 may be directly disposed at the assembly position, or it may be moved to the assembly position by a moving mechanism and then fixed at the assembly position.

[0042] The second positioning fixture 200, in its first state, is used to position the end plate in the first direction Y and the third direction X, thereby achieving a good positioning effect for the end plate. The second positioning fixture 200 may include a second positioning platform and second elastic limiting blocks disposed on the second positioning platform. At least two second elastic limiting blocks are provided opposite each other. In the first state, the two oppositely disposed second elastic limiting blocks can limit the opposite sides of the battery cell module in the first direction Y or the second direction Z. Alternatively, the first positioning fixture 100 may include a second gripper that clamps the battery cell module in the first direction Y or the third direction X and a second driving component for driving the second gripper closer to or further away from the battery cell module, as long as the positioning effect of the battery cell module in the first direction Y and the third direction X is achieved. It should be noted that when the second positioning fixture 200 positions the end plate in the first direction Y and the third direction X, it refers to the state before the second positioning fixture 200 is driven by the aforementioned flipping drive device 300, that is, the initial state of the second positioning fixture 200 or the aforementioned first state.

[0043] The flipping drive device 300 is used to drive the second positioning fixture 200 to flip. The flipping drive device 300 may include a motor, which is connected to the second positioning fixture 200 via a drive shaft, or the motor may be connected to the second positioning fixture 200 via a linkage assembly. It is understood that when the flipping drive device 300 drives the second positioning fixture 200 to flip, the large surface of the end plate on the second positioning fixture 200 also flips. The large surface of the end plate (i.e., the assembly surface) has a state facing the end face of the cell module, and also a state perpendicular to the end face of the cell module. To ensure good battery quality, in some examples, when the cell module is assembled with the end plate, the end face of the cell module is usually parallel to the vertical direction. To assemble the end plate with the end face of the cell module, the flipping drive device 300 can drive the second positioning fixture 200 to flip to a second state, where the large surface of the end plate (i.e., the assembly surface) on the second positioning fixture 200 is facing the end face of the cell module, which facilitates subsequent alignment of the end plate with the end face of the cell module. Of course, the flipping drive device 300 can also drive the second positioning fixture 200 to flip so that the large surface (i.e., the assembly surface) of the end plate on it is parallel to the third direction X, that is, the large surface (i.e., the assembly surface) of the end plate is facing the second direction Z. When the end plate is placed on the second positioning fixture 200, the first positioning fixture 100 can avoid the walking path of the robot arm after grasping the end plate, so that the robot arm can place the end plate on the second positioning fixture 200. It is also convenient to adjust the position of the end plate on the second positioning fixture 200, so that the second positioning fixture 200 can accurately position the end plate before flipping it. At this time, the flipped end plate is still relatively stable, which improves the assembly accuracy of the end plate and the battery cell module in subsequent assembly. It should be noted that the relative position of the positioning area of ​​the second positioning fixture 200 of the assembly equipment and the first positioning fixture 100 can be adjusted in advance so that after the second positioning fixture 200 is flipped, the end plate it positions can be aligned with the end face of the battery cell module in the first direction Y and the second direction Z. In this way, the end plate can be directly positioned on the second positioning fixture 200 each time, and then flipped by the flipping drive device 300 to achieve the effect of the end plate being aligned with the end face of the battery cell module in the first direction Y and the second direction Z, thereby improving the accuracy of the assembly of the end plate and the battery cell module.

[0044] Traditional assembly equipment typically involves first flipping the end plate to a vertical position before positioning it. This requires moving the end plate to another platform for positioning, necessitating a transfer mechanism. This results in numerous assembly steps and complex equipment. Furthermore, when positioning the end plate on the assembly platform, space limitations prevent direct alignment of the end plate's assembly surface with the cell module's end face. A flipping or translation mechanism is still needed to move the end plate to a position opposite the cell module's end face, followed by another drive mechanism to bring the end plate and cell module's end face together, completing the assembly process. This makes the assembly equipment complex and bulky. Even if the end plate can be aligned with the cell module's end face on the assembly platform, sufficient space must be left between them to allow for the transfer mechanism, still resulting in a large assembly equipment. This also increases the risk of interference with the cell module during transfer, reducing the cell module's stability and consequently lowering assembly accuracy.

[0045] Compared to traditional assembly equipment that first flips the end plate and then places it and the battery cell module onto the assembly platform for assembly, this application uses a flipping drive device 300 connected to a second positioning fixture 200. By driving the second positioning fixture 200 to flip, the end plate can be directly moved onto the second positioning fixture 200 connected to the flipping drive device 300 for pre-positioning. After flipping, it can approach and assemble with the end face of the battery cell module, eliminating the need for transferring the end plate between the positioning and flipping processes. Therefore, the assembly equipment of this application requires fewer assembly steps for the end plate and battery cell module, achieves higher assembly accuracy, and has a simpler structure and smaller size.

[0046] The moving drive device 400 refers to the drive device that moves the second positioning fixture 200 toward the end face of the battery cell module. The moving drive device 400 is connected to the second positioning fixture 200 by transmission, either directly or through other transmission mechanisms. The moving drive device 400 can be a cylinder, a lead screw and nut assembly, or a gear and rack assembly, etc. It is understood that when the flipping drive device 300 is mechanically connected to the second positioning fixture 200, the moving drive device 400 also drives the flipping drive device 300 to move together along a third direction X, so that the end plate is assembled with the end face of the battery cell module.

[0047] The technical solution of the present invention provides a first positioning fixture 100, which can position the battery cell module in the first direction Y and the second direction Z. A second positioning fixture 200 is provided on one side of the first positioning fixture 100 along the third direction X, and in the first state, it is used to position the end plate in the first direction Y and the third direction X. This allows the second positioning fixture 200 to be oriented towards the second direction Z, which facilitates the positioning of the end plate onto the second positioning fixture 200 and reduces the risk of interference between the first positioning fixture 100 and the positioning of the end plate.

[0048] By connecting the flipping drive device 300 to the second positioning fixture 200, the second positioning fixture 200 is flipped to the second state, so that the assembly surface of the end plate faces the third direction and is aligned with the end face of the battery cell module in the first direction Y and the second direction Z. The moving drive device 400 is connected to the second positioning fixture 200 and drives the second positioning fixture 200 to move along the third direction X when the second positioning fixture 200 is in the second state. Thus, the end plate positioned on the second positioning fixture 200 can achieve a precise assembly effect with the battery cell module simply by flipping and translating. In this assembly process, the positioning, flipping and assembly processes of the end plate with the end face of the battery cell module are all performed on the second positioning fixture 200 without the need to switch to other platforms, thereby further improving the assembly accuracy and efficiency of the end plate and the battery cell module, simplifying the structure of the assembly equipment and reducing the size of the assembly equipment.

[0049] Please refer to the reference. Figures 1 to 3 In some embodiments of the present invention, the first positioning fixture 100 includes a lateral clamping mechanism 110 and a lifting mechanism 120. Two lateral clamping mechanisms 110 are provided, and the two lateral clamping mechanisms 110 are arranged opposite to each other in the first direction Y and respectively abut against the opposite sides of the battery cell module; the lifting mechanism 120 limits the battery cell module in the second direction Z.

[0050] The lateral clamping mechanism 110 refers to a mechanism used to clamp the battery cell module laterally. This lateral clamping mechanism 110 can be a mechanism that clamps the battery cell module in a front-to-back direction or a mechanism that clamps the battery cell module in a left-to-right direction, as long as it can avoid the end face of the battery cell module. In one example, the lateral clamping mechanism 110 may include a cylinder and a clamping plate driven by the cylinder. The cylinder drives the clamping plate to move towards the battery cell module to clamp it, or the cylinder drives the clamping plate to move away from the battery cell module to release it. In another example, the lateral clamping mechanism 110 includes a fixed bracket, a support block, and a spring. The two ends of the spring are respectively connected to the fixed bracket and the support block. The support block abuts against two opposite sides of the battery cell module under the elastic action of the spring.

[0051] The lifting mechanism 120 refers to a mechanism capable of lifting the battery cell module. The lifting mechanism 120 may include a cylinder, a linear motor, a lead screw and nut assembly, a gear and rack assembly, or a connecting rod assembly, etc. The lifting mechanism 120 limits the battery cell module in the second direction Z, meaning that the second direction Z is the vertical direction.

[0052] By setting two opposing lateral clamping mechanisms 110, which are positioned opposite each other in the first direction Y and respectively abut against opposite sides of the battery cell module, the two lateral clamping mechanisms 110 are symmetrically arranged, thereby achieving the effect of centering the battery cell module in the first direction Y, improving the positioning accuracy of the battery cell module, and thus improving the assembly accuracy of the end plate and the end face of the battery cell module. The lifting mechanism 120 drives the battery cell module to move in the second direction Z, facilitating vertical adjustment of the battery cell module's position so that it can move to a height aligned with the flipped end plate, thereby achieving a precise fit between the end plate and the end face of the battery cell module.

[0053] Furthermore, it is understandable that if the support platform of the second positioning fixture 200 is vertical when transferring the end plate from the loading position, the end plate is prone to tilting due to gravity during positioning, making it difficult to guarantee a good positioning effect. In this embodiment, when the second direction Z is vertical, the end plate is horizontal when the second positioning fixture 200 limits its movement in the first direction Y and the third direction X. This facilitates transfer from the loading position to the second positioning fixture 200 using a robotic arm or similar gripping device. During positioning, it is not affected by interference from the battery module or the first positioning fixture 100, thus improving positioning efficiency and accuracy. Moreover, when the end plate is placed horizontally on the second positioning fixture 200, the placement platform of the second positioning fixture 200 provides good support for the bottom of the end plate, reducing the risk of tilting after positioning.

[0054] Please refer to the reference. Figures 1 to 3 In some embodiments of the present invention, the lateral clamping mechanism 110 includes a driving member 111 and a clamping member 112. The driving member 111 is convexly connected to the clamping member 112 and drives the clamping member 112 to move in the first direction Y. The clamping member 112 includes a base plate 1121 and a side plate 1122 connected to the base plate 1121. The side plate 1122 abuts against the battery cell module in the first direction Y, and the base plate 1121 supports the battery cell module in the second direction Z.

[0055] The drive component 111 can be a cylinder or a linear motor. The clamping component 112 can be a clamping plate or a clamping block, etc.

[0056] The clamping member 112 includes a base plate 1121 and a side plate 1122 connected to the base plate 1121. The base plate 1121 and the side plate 1122 can be an integral structure, or the base plate 1121 and the side plate 1122 can achieve a good connection effect through snap-fit, screw connection, bonding or welding.

[0057] By including a base plate 1121 and a side plate 1122 in the clamping member 112, the side plate 1122 abuts against the battery cell module in the first direction Y, thus achieving the effect of lateral positioning of the battery cell module; the base plate 1121 supports the battery cell module in the second direction Z, thus further achieving the effect of positioning the bottom of the battery cell module. This allows the lifting mechanism 120 to drive the battery cell module and the lateral clamping mechanism 110 to rise and fall together, ensuring that the battery cell module has a stable posture during the lifting process.

[0058] Please refer to the reference. Figure 4 and Figure 5 In some embodiments of the present invention, the first positioning fixture 100 further includes a pressing mechanism 130, which and the lifting mechanism 120 respectively limit the battery cell module on opposite sides in the second direction Z.

[0059] The pressing mechanism 130 refers to a mechanism capable of applying downward pressure to the battery cell module. The pressing mechanism 130 includes a frame 131, a power unit 132 mounted on the frame 131, and a pressing body 133 that is driveably connected to the power unit 132. The power unit 132 drives the pressing body 133 to move downwards to press the battery cell module. To reduce the risk of interference between the pressing mechanism 130 and the second positioning fixture 200, the frame 131 of the pressing mechanism 130 can be located on one side of the lateral clamping mechanism 110. The frame 131 includes a support body 1311 and a cantilever 1312. The cantilever 1312 is located at the top of the support body 1311 and extends in the first direction Y. The power unit 132 is located at the top of the cantilever 1312. Two cantilever arms 1312 can be provided, spaced apart in the third direction X. Each cantilever arm 1312's power unit 132 can drive the pressing body 133 downwards to press the battery cell module, thereby improving the stability of the battery cell module. The cantilever arms 1312 can slide on the top of the support body 1311, allowing adjustment of the distance between the two cantilever arms 1312 connected to the same support body 1311. This facilitates the pressing mechanism 130's applicability to pressing battery cell modules of different sizes, improving the compatibility of the pressing mechanism 130.

[0060] There may be one pressing mechanism 130, or there may be two or more pressing mechanisms 130. When there are at least two pressing mechanisms 130, the support frames in the at least two pressing mechanisms 130 may be respectively located on opposite sides of the battery cell module in the first direction Y, thereby reducing the risk of the battery cell module tilting.

[0061] By setting up a pressing mechanism 130, and limiting the battery cell module on both sides of the lifting mechanism 120 in the second direction Z respectively, the risk of the battery cell module shaking on the lifting mechanism 120 can be reduced.

[0062] Please refer to the reference. Figure 6 and Figure 7 In some embodiments of the present invention, the second positioning fixture 200 includes a bracket 220, a slide 230, and a fixture body 210. The bracket 220 is disposed on one side of the first positioning fixture 100 along the third direction X. The slide 230 is slidably disposed on the bracket 220 and is connected to the moving drive device 400. The flipping drive device 300 is disposed on the slide 230. When the second positioning fixture 200 is in the first state, the fixture body 210 is used to position the end plate in the first direction Y and the third direction X. The fixture body 210 is connected to the flipping drive device 300, and the rotation axis of the fixture body 210 is parallel to the first direction Y.

[0063] The bracket 220 can be a gantry frame or a box structure, as long as it can achieve a good supporting effect. There can be at least two brackets 220, which are arranged opposite each other along the first direction Y, so as to provide a good supporting effect for the opposite ends of the slide table 230 along the first direction Y.

[0064] The slide table 230 refers to a component that can slide and support the tooling body 210. The slide table 230 can extend along the first direction Y, and the flipping drive device 300 can be disposed in the middle of the slide table 230, so that the end plate on the tooling body 210 connected to the flipping drive device 300 can be aligned with the battery cell module along the first direction Y.

[0065] The tooling body 210 refers to a component capable of supporting and positioning the end plate. The tooling body 210 can be a device with grippers in both the first direction Y and the third direction X, or it can include a support platform 211 for supporting the end plate, with limiting structures on the support platform 211 capable of limiting the end plate in both the first direction Y and the third direction X. The limiting structures can be limiting blocks, limiting plates, or limiting posts, etc.

[0066] By connecting the tooling body 210 with the flipping drive device 300, the end plate can be positioned on the tooling body 210 first, and then the tooling body 210 can be flipped by the flipping drive device 300 to achieve the effect of flipping the end plate to a vertical state. Then, by setting the flipping drive device 300 on the slide table 230, which is slidably set on the bracket 220, the moving drive device 400 drives the slide table 230 to move in the third direction X, thereby achieving the effect of precisely assembling the end plate and the battery cell module.

[0067] Please refer to the reference. Figure 6 and Figure 7 In some embodiments of the present invention, when the second positioning fixture 200 is in the first state, the fixture body 210 includes a support platform 211, a first limiting component 212, and a second limiting component 213. The support platform 211 is used to support the end plate; the first limiting component 212 is disposed on the support platform 211 and limits the end plate in the first direction Y; the second limiting component 213 is disposed on the support platform 211 and limits the end plate in the third direction X; the first limiting component 212, the second limiting component 213, and the support platform 211 together enclose a positioning space for positioning the end plate.

[0068] The support platform 211 refers to a platform used to support the end plate. The support platform 211 can be flat, or the support platform 211 includes a flat plate and multiple support blocks disposed on the flat plate, with the multiple support blocks used to jointly support the end plate.

[0069] The first limiting component 212 may include one limiting member or at least two limiting members. When the first limiting component 212 includes at least two limiting members, one of the limiting members in the two first limiting components 212 may include a fixed limiting member and the other may include a movable limiting member. The fixed limiting member and the movable limiting member are arranged opposite to each other in the first direction Y and respectively abut against opposite sides of the end plate in the first direction Y, thereby improving the positioning stability of the end plate in the first direction. The fixed limiting member may be a fixed limiting plate, a fixed limiting block, or a fixed limiting post; the movable limiting member can move relative to the support platform 211 in the first direction Y, so as to move closer to or further away from the fixed limiting member, thereby clamping the end plate or releasing the end plate in the first direction Y together with the fixed limiting member. In some embodiments, the movable limiting member may be driven in the first direction Y by a cylinder, a linear motor, a gear and rack assembly, or a lead screw and nut assembly. Of course, in other examples, the limiting members in both first limiting components 212 may both be movable limiting members.

[0070] The second limiting component 213 is used to limit the end plate in the third direction X. The structure of the second limiting component 213 is similar to that of the first limiting component 212, and will not be described in detail here.

[0071] By setting up the support platform 211, the end plate can be limited in the second direction Z. Furthermore, when both the first direction Y and the third direction X are horizontal, the support platform 211 provides good support for the end plate, thereby reducing the risk of the end plate tilting after being positioned on the second positioning fixture 200 due to its own weight. By setting up the first limiting component 212 and the second limiting component 213, the end plate can also be limited in both the first direction Y and the third direction X.

[0072] Please refer to the reference. Figure 6 and Figure 7 In some embodiments of the present invention, when the second positioning fixture 200 is in the first state, the second limiting component 213 includes a first movable limiting member 2131, an elastic member 2132, a second movable limiting member 2133, and a driving mechanism. The two ends of the elastic member 2132 are respectively connected to the first movable limiting member 2131 and the support platform 211, and the elastic member 2132 extends along the third direction X. The second movable limiting member 2133 is disposed opposite to the first movable limiting member 2131 in the third direction X and is slidably disposed on the support platform 211. The driving mechanism is connected to the second movable limiting member 2133 in a transmission connection and drives the second movable limiting member 2133 to move closer to or away from the first movable limiting member 2131 along the third direction X.

[0073] The first movable limiting member 2131 refers to a component that can move in a third direction X. The first movable limiting member 2131 can be block-shaped, plate-shaped, or column-shaped, etc.

[0074] The second movable part refers to a component that can move in a third direction X. The second movable limiting part 2133 can also be block-shaped, plate-shaped, or column-shaped, etc.

[0075] The elastic element 2132 refers to a component that can provide elastic deformation, which can be a spring or a sheet, etc.

[0076] The drive mechanism refers to the mechanism used to drive the second movable limit member 2133 to move in the third direction X, and to enable the second movable limit member 2133 to be positioned at any position in the third direction X. Specifically, the drive mechanism can be a linear motor, a cylinder, or a lead screw and nut assembly.

[0077] By connecting the drive mechanism to the second movable limit member 2133 and driving the second movable limit member 2133 to move along the third direction X, the height of the second movable limit member 2133 after flipping can be adjusted, thereby adjusting the vertical height of the end plate after flipping. By connecting the two ends of the elastic member 2132 to the support platform 211 and the first movable limit member 2131 respectively, and extending it along the third direction X, the process of fine-tuning the height of the flipped end plate can be avoided. This configuration achieves the effect of fine-tuning the height of the end plate after flipping.

[0078] It should be noted that, for ease of operation, the position of the end plate in the third direction X can be fine-tuned before it is flipped (i.e., when it is in a horizontal state). Of course, in some other examples, if the operating space allows, the end plate can also be fine-tuned after it has been flipped.

[0079] In some embodiments of the present invention, when the second positioning fixture 200 is in a first state, the first movable limiting member 2131 is disposed on the side of the second movable limiting member 2133 away from the first positioning fixture 100 along the third direction X.

[0080] With this configuration, when the end plate is flipped and in a vertical position, its bottom can abut against the first movable limiting member 2131. Since the first movable limiting member 2131 does not undergo elastic deformation, it can provide good support for the end plate and reduce the risk of the end plate changing position in the vertical direction.

[0081] This invention also proposes an assembly method based on the above-described assembly equipment. The specific structure of the assembly equipment is as described in the above embodiments. Since this assembly method is based on the assembly equipment described above, it adopts all the technical solutions of all the above embodiments, and therefore possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. For example, Figure 8 As shown, the assembly method includes: S10: Control the first positioning fixture 100 to position the battery cell modules and place them in the assembly position; S20: Control the second positioning fixture 200 to position the end plate; S30: Control the flipping drive device 300 to open, so as to drive the second positioning fixture 200 to flip, so that the assembly surface of the end plate is aligned with the end face of the cell module in the first direction Y and the second direction Z. S40: Control the activation of the mobile drive device 400 to drive the second positioning fixture 200 to move along the third direction X and assemble with the end face of the battery cell module.

[0082] When the first positioning fixture 100 positions the battery cell module, it positions it in the first direction Y and the second direction Z. The first positioning fixture 100 may include a first positioning platform and a first elastic limiting block disposed on the first positioning platform. At least two first elastic limiting blocks are provided opposite each other, and the two oppositely disposed first elastic limiting blocks can limit the battery cell module on opposite sides in the first direction Y or the second direction Z. Alternatively, the first positioning fixture 100 may include a first gripper that clamps the battery cell module in the first direction Y or the second direction Z and a first driving component for driving the first gripper to move closer to or away from the battery cell module, as long as the positioning effect of the battery cell module in the first direction Y and the second direction Z can be achieved. The first positioning fixture 100 may be directly disposed at the assembly position, or it may be driven to the assembly position by other driving mechanisms. Other driving mechanisms may include at least one of a lifting mechanism 120, a translation mechanism, or a flipping mechanism. The assembly position can be a location set by the operator on the assembly equipment's operating interface, whereby the first positioning fixture 100 is controlled to be positioned at the assembly position according to a pre-defined control program. Alternatively, a limiting device can be installed near the assembly position, blocking the first positioning fixture 100 when it moves to the assembly position, thus achieving the effect of placing the first positioning fixture 100 at the assembly position. The position is determined after limiting the first positioning fixture 100. In this invention, the assembly position is located where, after the end plate on the second positioning fixture 200 is flipped, the battery cell module on the first positioning fixture 100 can be aligned with the end plate in both the first direction Y and the second direction Z.

[0083] The second positioning fixture 200 is a fixture capable of positioning the end plate in the first direction Y and the third direction X. The structure of the second positioning fixture 200 can be similar to that of the first positioning fixture 100, and will not be described in detail here. It should be noted that the positioning of the end plate by the second positioning fixture 200 in the first direction Y and the third direction X is based on its initial state, that is, the state before the second positioning fixture 200 is flipped. For example, taking the second direction Z as a vertical state, the second positioning fixture 200 positions the end plate in the horizontal direction.

[0084] When the flipping drive device 300 drives the second positioning fixture 200 to flip, the rotation axis of the second positioning fixture 200 can be parallel to the first direction Y or parallel to the third direction X. However, in order to make the flipped second positioning fixture 200 aligned with the end face of the battery cell module in the first direction Y and the second direction Z, and to drive the end plate to move along the third direction X to assemble with the end face of the battery cell module, the flipping drive device 300 can drive the second positioning fixture 200 to rotate around the rotation axis parallel to the first direction Y.

[0085] It is understandable that in order to enable the second positioning fixture 200 to move along the axis parallel to the first direction Y and to avoid interference with the battery cell module, a certain distance is provided between the flipped end plate and the end face of the battery cell module. Therefore, in order to achieve the effect of assembling the end plate with the end face of the battery cell module, the motion drive device 400 needs to be able to drive the second positioning fixture 200 to move along the third direction X to approach the end face of the battery cell module.

[0086] The assembly method of this invention first controls the first positioning fixture 100 to position the battery cell module and place it in the assembly position, thus ensuring the battery cell module has a stable and unchanging state. By controlling the second positioning fixture 200 to position the end plate, the end plate can be pre-positioned, reducing the risk of tilting or shaking when it moves towards the battery cell module. Then, by activating the flipping drive device 300 and driving the second positioning fixture 200 to flip, the assembly surface of the end plate is aligned with the end face of the battery cell module in the first direction Y and the second direction Z. Finally, the moving drive device 400 is activated and drives the second positioning fixture 200 to move along the third direction X. Thus, the end plate positioned on the second positioning fixture 200 can achieve precise assembly with the battery cell module simply through flipping and translational movements. During this assembly process, the positioning, flipping, and assembly of the end plate with the end face of the battery cell module are all carried out on the second positioning fixture 200. There is no need to switch to other platforms, which reduces the risk of decreased accuracy after the end plate is transferred. This further improves the assembly accuracy and efficiency of the end plate and the battery cell module, simplifies the structure of the assembly equipment, and reduces the size of the assembly equipment.

[0087] like Figure 9 As shown, in some embodiments of the present invention, the first positioning fixture 100 includes a lateral clamping mechanism 110 and a lifting mechanism 120. Two lateral clamping mechanisms 110 are provided, and the two lateral clamping mechanisms 110 are arranged opposite each other in the first direction Y, respectively abutting against opposite sides of the battery cell module; the lifting mechanism 120 limits the battery cell module in the second direction Z. S10: The step of controlling the first positioning fixture 100 to position the battery cell module and place it in the assembly position includes: S11: Control the lifting mechanism 120 to drive the battery cell module to move along the second direction Z to the assembly position; S12: Control the lateral clamping mechanism 110 to clamp the opposite sides of the battery cell module along the first direction Y.

[0088] The lateral clamping mechanism 110 refers to a mechanism used to clamp the battery cell module laterally. This lateral clamping mechanism 110 can be a mechanism that clamps the battery cell module in a front-to-back direction or a mechanism that clamps the battery cell module in a left-to-right direction, as long as it can avoid the end face of the battery cell module. In one example, the lateral clamping mechanism 110 may include a cylinder and a clamping plate driven by the cylinder. The cylinder drives the clamping plate to move towards the battery cell module to clamp it, or the cylinder drives the clamping plate to move away from the battery cell module to release it. In another example, the lateral clamping mechanism 110 includes a fixed bracket, a support block, and a spring. The two ends of the spring are respectively connected to the fixed bracket and the support block. The support block abuts against two opposite sides of the battery cell module under the elastic action of the spring. By setting two lateral clamping mechanisms 110 that are arranged opposite each other in the first direction Y, and each abutting against the opposite sides of the battery cell module, the two lateral clamping mechanisms 110 are symmetrically arranged, thereby achieving the effect of centering the battery cell module in the first direction Y, improving the positioning accuracy of the battery cell module, and thus improving the assembly accuracy of the end plate and the end face of the battery cell module.

[0089] The lifting mechanism 120 refers to a mechanism capable of lifting and lowering the battery cell module. The lifting mechanism 120 may include a cylinder, a linear motor, a lead screw and nut assembly, a gear and rack assembly, or a connecting rod assembly, etc. The lifting mechanism 120 limits the battery cell module in the second direction Z, meaning the second direction Z is vertical. By driving the battery cell module to move in the second direction Z through the lifting mechanism 120, the position of the battery cell module can be adjusted vertically, allowing it to move to a height aligned with the flipped end plate, thus achieving a precise fit between the end plate and the end face of the battery cell module.

[0090] By driving the battery cell module to move in the second direction Z to the assembly position through the lifting mechanism 120, the risk of the battery cell module moving in the second direction Z can be reduced, that is, the risk of the battery cell module moving in the vertical direction can be reduced. Then, by clamping the opposite sides of the battery cell module along the first direction Y through the lateral clamping mechanism 110, the stability of the battery cell module in the assembly position is further improved. Furthermore, the battery cell module is driven to move along the second direction Z by the lifting mechanism 120. The second direction Z is the vertical direction, while the first direction Y and the third direction X can be two directions forming an angle on the horizontal plane. Therefore, when the end plate is positioned on the second positioning fixture 200, the end plate is in a horizontal state. At this time, it is convenient to transfer the end plate from the loading position to the second positioning fixture 200 by gripping devices such as robotic arms. The positioning of the end plate will not be affected by interference from the battery cell module and the first positioning fixture 100. Moreover, when the end plate is placed horizontally on the second positioning fixture 200, the placement platform of the second positioning fixture 200 can provide good support for the bottom of the end plate. The end plate is less likely to tilt after positioning, thereby improving the positioning stability of the end plate. This provides a stable foundation for the subsequent flipping drive device 300 to flip the end plate and the translation drive device 400 to translate the end plate, thereby improving the assembly accuracy of the end plate and the battery cell module.

[0091] like Figure 9 As shown, in some embodiments of the present invention, the first positioning fixture 100 further includes a pressing mechanism 130, which, together with the lifting mechanism 120, limits the relative positions of the battery cell module on opposite sides in the second direction Z. S10: After the step of controlling the lateral clamping mechanism 110 to clamp the relative positions of the battery cell module on opposite sides along the first direction Y, the following is further included: S13: Control the pressing mechanism 130 to press down to meet the battery cell module.

[0092] With this configuration, the pressing mechanism 130 and the lifting mechanism 120 respectively limit the battery cell module on opposite sides in the second direction Z, thereby reducing the risk of the battery cell module swaying on the lifting mechanism 120.

[0093] The present invention also proposes a battery production line, including assembly equipment. The specific structure of the assembly equipment is as described in the above embodiments. Since this battery production line adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0094] The above are merely exemplary embodiments of the present invention and do not limit the scope of the patent of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
