Description

Technical Field

[0001] The present invention relates to the field of battery technology, and in particular to a clamp device and a battery cell production line. Background Art

[0002] In the battery manufacturing industry, the outer shell of the battery generally needs to be wrapped in a welded and sealed metal shell. Therefore, during battery processing, there is a process that requires the battery to be clamped and fixed and then positioned in the welding position.

[0003] In the related technology, the existing welding fixture requires the fixture to stop and then open. After the fixture is opened, the battery is clamped from the assembly line to the turntable fixture on the welding machine. After clamping, the fixture is closed again. Finally, the fixture is moved to the welding station, and the laser welds the four sides. Each time an edge is processed, the fixture rotates 90° at the fixed station, and the welding head moves back and forth in a straight line along the welding track before processing the next edge. After welding is completed, release the fixture, take the battery out of the turntable fixture, and put it back on the assembly line. The entire process is flipped at the fixture fixed station, and then moved to the next station after welding is completed. The total processing time of the process is long. Summary of the invention

[0043] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0044] Reference below Figure 1-Figure 14 The clamp device 100 according to an embodiment of the present invention is described, which can enable the battery cell positioning mechanism 2 to achieve continuous flipping during the conveying process of the conveyor line, saving the stop time of the clamp device 100 and the product replacement time consumed by carrying the battery cell 200, thereby reducing the process processing time and improving production efficiency.

[0045] Combination Figure 1-Figure 14 As shown, the fixture device 100 according to the first aspect of the present invention includes a conveyor line matching seat 1, a battery cell positioning mechanism 2 and a rotary drive mechanism 3. Among them, the conveyor line matching seat 1 is usually installed on the conveyor belt of the production line, and is used to fix and support the entire fixture device 100, which can ensure the stability of the fixture device 100 during operation and prevent position displacement caused by vibration or external force; the battery cell positioning mechanism 2 can accurately position and fix the battery cell 200 to ensure that the battery cell 200 is in the correct predetermined position in the subsequent processing steps; the rotary drive mechanism 3 can enable the battery cell positioning mechanism 2 to rotate around a certain axis, thereby changing the direction or angle of the battery cell 200 to meet the requirements of different processing steps (for example, it can allow the battery cell 200 to be welded, tested or other processing operations at different angles, improving processing efficiency and quality).

[0046] Specifically, the conveyor line matching seat 1 is suitable for being arranged on the conveyor line to move along the conveying direction of the conveyor line, the battery cell positioning mechanism 2 is used to position the battery cell 200, the battery cell positioning mechanism 2 is rotatably arranged on the conveyor line matching seat 1, the rotation drive mechanism 3 is connected to the battery cell positioning mechanism 2, and the rotation drive mechanism 3 selectively controls the battery cell positioning mechanism 2 to rotate relative to the conveyor line matching seat 1. For example, the conveyor line matching seat 1 can be fixed on a magnetic suspension conveyor line, a ring line or a synchronous belt drive conveyor line.

[0047] Specifically, the conveyor line matching seat 1 is connected to the conveyor line, and the conveyor line matching seat 1 can move along the conveying direction of the conveyor line, so that the conveyor line matching seat 1 drives the battery cell positioning mechanism 2 to move along the conveying direction of the conveyor line. At the same time, the battery cell positioning mechanism 2 is connected to the rotating drive mechanism 3. In this way, when the battery cell positioning mechanism 2 moves along the conveyor line, the rotating drive mechanism 3 can also control the battery cell positioning mechanism 2 to flip at different angles, thereby realizing the non-carrying and continuous operation effect of the production line, reducing the stop time of the clamp device 100 and the product replacement time spent on transporting the product, thereby reducing the product processing time and improving production efficiency.

[0048] Compared with the traditional welding fixture (which requires the fixture to stop and then open, after the fixture is opened, the product is clamped from the assembly line to the turntable fixture on the welding machine, clamped, and then closed. Finally, the fixture is moved to the welding station, and the laser welds the four sides. Each time an edge is processed, the fixture rotates 90° at the fixed station, and the welding head moves back and forth in a straight line along the welding trajectory, and then processes the next edge. After welding is completed, the fixture is released, the product is taken out of the turntable fixture, and put back on the assembly line. The entire welding process is flipped at the fixture fixed station, and then transported to the next station after welding is completed. The total processing time of the process is long), the embodiment in this case does not need to be removed from the conveyor line separately. It can complete flipping at different angles and weld different surfaces of the product during the conveying process of the conveyor line, thereby realizing the non-transportation and continuous operation effect of the production line, thereby reducing the product processing time and improving production capacity.

[0049] For example, the embodiment in this case can complete the flipping actions of 90°, 180°, and 270° in sequence during the movement of the battery cell positioning mechanism 2, and the flipping is not limited by the work station and can rotate continuously at any place during the movement of the conveyor line. This can effectively shorten the total time for loading and unloading and improve the overall machine beat.

[0050] Therefore, by setting up the clamp device 100, the battery cell positioning mechanism 2 can be continuously flipped during the conveying process of the conveyor line, saving the stop time of the clamp device 100 and the product replacement time consumed by transporting the battery cell 200, thereby reducing the process processing time and improving production efficiency.

[0051] According to some optional embodiments of the present invention, Figure 1 , Figure 2 , Fig. 9 and Fig.14As shown, the rotation drive mechanism 3 includes a first active mechanism 31 and a first driven mechanism 32. The first active mechanism 31 is spaced apart from the battery cell positioning mechanism 2, and the first driven mechanism 32 is connected to the battery cell positioning mechanism 2. When the conveyor line matching seat 1 moves to a predetermined rotation position, the first driven mechanism 32 cooperates with the first active mechanism 31, and the first driven mechanism 32 drives the battery cell positioning mechanism 2 to rotate relative to the conveyor line matching seat 1 under the action of the first active mechanism 31.

[0052] Among them, the first driven mechanism 32 is connected to the battery cell positioning mechanism 2. When the conveyor line matching seat 1 drives the first driven mechanism 32 to move to a predetermined rotation position, the first driven mechanism 32 on the battery cell positioning mechanism 2 cooperates with the first active mechanism 31. At this time, the first driven mechanism 32 can drive the battery cell positioning mechanism 2 to rotate relative to the conveyor line matching seat 1 under the interaction between it and the first active mechanism 31, thereby smoothly realizing the rotation effect of the battery cell positioning mechanism 2 during the conveyor belt transportation process.

[0053] In detail, the embodiments in this case are mainly aimed at the fixation of long battery welding, which can realize the non-carrying continuous operation of the production line and complete the required functional conversion during movement; since the installation of the transmission conveyor line does not affect the use of the fixture, the fixture can be installed on various conveyor lines, such as magnetic levitation, synchronous belt conveyor line, ring line, chain conveyor line and other conveyor systems. In addition, the processed products targeted by the embodiments in this case include but are not limited to welding fixtures that can be used for long batteries and short batteries, and can also be used for other workstations that require flipping, such as multi-sided flipping of batteries for air blowing and dust removal, flipping of multi-sided tape, etc.

[0054] Specifically, combined Figure 1 , Figure 2 , Fig. 9 and Fig.14 As shown, the first active mechanism 31 and the first driven mechanism 32 are separately arranged, and the first active mechanism 31 is suitable for being located on one side of the conveyor line. Such an arrangement can facilitate the operator to perform separate maintenance and replacement of one of the first active mechanism 31 and the first driven mechanism 32, and can also effectively utilize the space on one side of the conveyor line, thereby improving the assembly and disassembly flexibility of the rotary drive mechanism 3 and the rationality of the spatial layout.

[0055] Furthermore, combined with Figure 1 , Figure 2 , Fig. 9 and Fig.14As shown, the first active mechanism 31 is provided with a groove 311 with varying height along the conveying direction of the conveyor line, and the first driven mechanism 32 is provided with a first follower 321, and the first follower 321 rotates around the rotation axis of the battery cell positioning mechanism 2; when the conveyor line matching seat 1 moves to a predetermined rotation position, the first follower 321 can be movably engaged in the groove 311, so that the first follower 321 drives the battery cell positioning mechanism 2 to rotate when sliding in the groove 311.

[0056] That is to say, the first active mechanism 31 can guide and control the movement of the first driven mechanism 32 through the groove 311 with varying heights, so that the first driven mechanism 32 can achieve the effect of driving the battery cell positioning mechanism 2 to rotate at a predetermined rotational position. For example, as the conveyor line moves, the first follower 321 on the first driven mechanism 32 also continues to slide in the groove 311. Due to the height variation of the groove 311, the first follower 321 will move up and down along the contour of the groove 311 and be converted into the rotational movement of the battery cell positioning mechanism 2, so that the battery cell 200 can achieve the effect of automatic flipping during the movement of the conveyor line, avoiding manual downtime to intervene in the process of flipping and welding the battery cell 200, thereby reducing the product processing time, improving the processing automation effect, and further increasing production capacity.

[0057] Specifically, combined Figure 1 and Fig.14 As shown, the first driven mechanism 32 further includes a driven disk 322 , which is connected to the battery cell positioning mechanism 2 , and whose rotation center is located at the rotation axis of the battery cell positioning mechanism 2 . The first follower 321 is disposed on the driven disk 322 .

[0058] It can be understood that the driven disk 322 can serve as a transmission component for the rotational motion of the battery cell positioning mechanism 2 (the driven disk 322 converts the movement of the first follower 321 into the rotational motion of the battery cell positioning mechanism 2), and the rotation center of the driven disk 322 is aligned with the rotation axis of the battery cell positioning mechanism 2, thereby ensuring that the two rotate synchronously and the accuracy of the rotation angle is guaranteed.

[0059] In addition, the first follower 321 is located on the radial side of the rotation center of the driven disk 322, so that the first follower 321 forms an extension effect in the radial direction of the driven disk 322, thereby ensuring that the first follower 321 can drive the driven disk 322 to rotate along its own rotation center at a corresponding angle when sliding in the groove 311 with varying height.

[0060] Furthermore, combined with Fig.14As shown, there are at least two first followers 321, and they are symmetrically arranged about the rotation center of the driven disk 322. Such an arrangement can better balance the force on the driven disk 322 and reduce the eccentric load. It can also help to reduce the risk of vibration and jitter caused by a single first follower 321, so that the rotation of the driven disk 322 is smoother. The position errors can also be corrected to make the rotation of the driven disk 322 more precise (even if the position of one first follower 321 is slightly deviated, the other followers can compensate for this error), and the joint action of multiple first followers 321 can make the rotation of the driven disk 322 smoother, reduce the risk of mutation and impact caused by a single first follower 321, thereby improving the stability and reliability of the rotation positioning mechanism.

[0061] Specifically, combined Fig. 9 As shown, the groove 311 includes a first straight groove section 3111, a second straight groove section 3112 and a bent groove section 3113. In the conveying direction of the conveyor line, the bent groove section 3113 is bently connected between the first straight groove section 3111 and the second straight groove section 3112, and the first straight groove section 3111 is higher or lower than the second straight groove section 3112.

[0062] That is to say, the first straight groove section 3111 and the second straight groove section 3112 have different heights, and the bent groove section 3113 is bently connected between the first straight groove section 3111 and the second straight groove section 3112, which can serve as a transition section with height change, thereby ensuring the movement continuity of the first follower 321 in the groove 311.

[0063] For example, when the clamp device 100 moves on the conveyor line, the first follower 321 is in the first straight slot section 3111. At this time, the battery cell positioning mechanism 2 maintains its original action state. As the conveyor line continues to move, the first follower 321 enters the bending slot section 3113. Due to the height change of the bending slot section 3113, the first follower 321 will move up and down along the contour of the bending slot section 3113, and the up and down movement of the first follower 321 is converted into the rotational movement of the driven disk 322. The rotation center of the driven disk 322 is aligned with the rotation axis of the battery cell positioning mechanism 2. Therefore, the rotation of the driven disk 322 will drive the battery cell positioning mechanism 2 to rotate together. When the first follower 321 reaches the second straight slot section 3112, the battery cell positioning mechanism 2 has completed the predetermined rotation action and remains in the existing action position.

[0064] Furthermore, there are multiple first active mechanisms 31 , and the multiple first active mechanisms 31 are arranged at intervals along the conveying direction of the conveying line, so that the first driven mechanism 32 drives the battery cell positioning mechanism 2 to rotate multiple times.

[0065] Among them, multiple first active mechanisms 31 are arranged at intervals along the conveying direction of the conveyor line, so that as the conveyor line moves, the first driven mechanism 32 can cooperate with the first active mechanism 31 multiple times, so that the first driven mechanism 32 can drive the battery cell positioning mechanism 2 to rotate multiple times, thereby facilitating the welding process on different surfaces of the battery cell 200.

[0066] Specifically, combined Figure 5 As shown, the first active mechanism 31 includes a motor 312 , and the first driven mechanism 32 includes a reducer 323 , and the motor 312 is drivingly connected to the reducer 323 .

[0067] It can be understood that the motor 312 can provide rotational power for the battery cell positioning mechanism 2, and can also accurately control the rotation angle and speed of the battery cell positioning mechanism 2. The reducer 323 can convert the high-speed and low-torque output of the motor 312 into a low-speed and high-torque output. In this way, by reducing the output speed of the motor 312, the output torque of the motor 312 to the battery cell positioning mechanism 2 can be increased, thereby improving the transmission reliability of the battery cell positioning mechanism 2 and the rotating drive mechanism 3.

[0068] According to some optional embodiments of the present invention, Figure 2 , Figure 3 , Figure 5 and Fig.14 As shown, the clamp device 100 also includes a rotary locking mechanism 4, which selectively unlocks and locks the battery cell positioning mechanism 2; wherein, after the rotary locking mechanism 4 unlocks the battery cell positioning mechanism 2, the rotary drive mechanism 3 controls the battery cell positioning mechanism 2 to rotate relative to the conveyor line mating seat 1.

[0069] That is to say, the rotation locking mechanism 4 can ensure that the battery cell positioning mechanism 2 remains fixed when there is no need to rotate, and can rotate freely when there is a need to rotate, thereby preventing the risk of accidental rotation of the battery cell positioning mechanism 2 and improving the rotation accuracy. In addition, the rotation locking mechanism 4 can also lock the battery cell positioning mechanism 2 in a precise position after the battery cell positioning mechanism 2 rotates, thereby ensuring the accuracy of the subsequent welding process. Among them, the rotation locking mechanism 4 can selectively unlock and lock the battery cell positioning mechanism 2 according to different working conditions and needs, which can also improve the operational flexibility.

[0070] Specifically, combined Figure 1 , Figure 2 , Figure 8 and Fig.14As shown, the rotary locking mechanism 4 includes a second active mechanism 41 and a second driven mechanism 43. The second active mechanism 41 is spaced apart from the battery cell positioning mechanism 2. The second driven mechanism 43 is locked with the battery cell positioning mechanism 2, and the second driven mechanism 43 is movable relative to the conveyor line matching seat 1. When the conveyor line matching seat 1 moves to a predetermined unlocking position, the second driven mechanism 43 cooperates with the second active mechanism 41, and the second driven mechanism 43 unlocks the battery cell positioning mechanism 2 by moving under the action of the second active mechanism 41.

[0071] It can be understood that the cooperation between the second active mechanism 41 and the second driven mechanism 43 can enable the rotary locking mechanism 4 to accurately lock and unlock the battery cell positioning mechanism 2, thereby ensuring the stability and position accuracy of the battery cell positioning mechanism 2 in different operation stages, thereby improving the production efficiency and product yield of the production line.

[0072] Among them, the second follower mechanism 43 is arranged on the battery cell positioning mechanism 2, and the second follower mechanism 43 is movable relative to the battery cell positioning mechanism 2. When there is no need to flip the battery cell positioning mechanism 2, the second follower mechanism 43 is locked and matched with the battery cell positioning mechanism 2, so as to ensure the position stability of the battery cell 200, and further ensure the accuracy of the subsequent processing steps of the battery cell 200; when the battery cell positioning mechanism 2 has a need to flip, at this time, when the conveyor line matching seat 1 drives the battery cell positioning mechanism 2 to move to a predetermined unlocking position, the second follower mechanism 43 unlocks the battery cell positioning mechanism 2 by moving under the action of the second active mechanism 41, so that the battery cell positioning mechanism 2 can be flipped at a specified position, thereby facilitating the processing of different surfaces of the battery cell 200, thereby reducing manual intervention in the flipping process of the battery cell 200 and improving the production automation effect.

[0073] Furthermore, the second active mechanism 41 and the second driven mechanism 43 are separately arranged, and the second active mechanism 41 is suitable for being located on one side of the conveyor line. Such an arrangement can facilitate the operator to perform separate maintenance and replacement of one of the second active mechanism 41 and the second driven mechanism 43, and can also effectively utilize the space on one side of the conveyor line, thereby improving the assembly and disassembly flexibility of the rotary locking mechanism 4 and the rationality of the spatial layout.

[0074] Specifically, combined Figure 1 , Figure 2 and Figure 8 As shown, the second active mechanism 41 is provided with a first extrusion surface 411 with variable dimensions along a direction perpendicular to the conveying direction of the conveyor line, and the second driven mechanism 43 is provided with a second follower 431; when the conveyor line mating seat 1 moves to a predetermined unlocking position, the second follower 431 is suitable for contacting and mating with the first extrusion surface 411, and the second follower 431 moves relative to the conveyor line mating seat 1 under the action of the first extrusion surface 411, thereby unlocking the battery cell positioning mechanism 2.

[0075] It can be understood that along the conveying direction perpendicular to the conveyor line, the position of the second active mechanism 41 is relatively fixed with the position of the conveyor line matching seat 1, and the second active mechanism 41 also forms a first extrusion surface 411 with variable size. The position of the second follower 431 on the second driven mechanism 43 can be passively changed relative to the conveyor line matching seat 1 when it contacts and cooperates with the first extrusion surface 411, thereby achieving the effect of smoothly unlocking the battery cell positioning mechanism 2, thereby improving the flipping automation effect of the battery cell positioning mechanism 2.

[0076] Furthermore, combined with Figure 1 , Figure 2 and Figure 8 As shown, the first extrusion surface 411 includes a first protruding section 4111 and a first recessed section 4112. The first protruding section 4111 protrudes toward one side of the second follower 431. The distance from the first recessed section 4112 to the second follower 431 is greater than the distance from the first protruding section 4111 to the second follower 431. The first recessed section 4112 is connected to both sides of the first protruding section 4111.

[0077] Among them, when the first raised section 4111 is in contact and cooperate with the second follower 431, the second follower 431 moves relative to the battery cell positioning mechanism 2 toward the inner side of the conveyor line matching seat 1, so that the second follower 431 drives the second follower mechanism 43 to unlock the battery cell positioning mechanism 2. When the first recessed section 4112 is in contact and cooperate with the second follower 431, the second follower 431 moves relative to the battery cell positioning mechanism 2 toward the outer side of the conveyor line matching seat 1. At this time, the second follower 431 drives the second follower mechanism 43 and the battery cell positioning mechanism 2 to be in a locked state. In this way, the unlocking and locking states of the battery cell positioning mechanism 2 can be achieved by selectively contacting and cooperating the second follower 431 with the first raised section 4111 or the first recessed section 4112, thereby ensuring the position stability and flipping flexibility of the battery cell positioning mechanism 2.

[0078] In addition, the first recessed section 4112 is connected to both sides of the first raised section 4111, so that the battery cell positioning mechanism 2 can be in a locked state before and after the unlocking process, thereby improving the position stability of the battery cell positioning mechanism 2 in the same processing stage (that is, when there is no flipping requirement).

[0079] Specifically, combined Figure 1 , Figure 2 and Figure 8As shown, the second follower mechanism 43 includes a mounting seat 432 and a locking member 433. The mounting seat 432 is located at one end of the battery cell positioning mechanism 2, and the mounting seat 432 is movable relative to the conveyor line matching seat 1. The second follower 431 is arranged on the mounting seat 432, and the locking member 433 is arranged on the mounting seat 432, and the locking member 433 is locked and matched with the battery cell positioning mechanism 2.

[0080] It can be understood that the mounting seat 432 can provide a fixed installation position for the locking member 433 and the second follower 431. The mounting seat 432 can move relative to the conveying line matching seat 1 in a direction perpendicular to the conveying direction of the conveyor line. When the second follower 431 comes into contact and matches with the first extrusion surface 411 with a changed size, the second follower 431 will drive the mounting seat 432 to passively shift, thereby causing the locking member 433 on the mounting seat 432 to move, and then the locking and unlocking matching effect between the locking member 433 and the battery cell positioning mechanism 2 is achieved through the movement of the locking member 433.

[0081] For example, the battery cell positioning mechanism 2 is fixed on the circular conveyor line, and the battery cell positioning mechanism 2 moves on the conveyor line. When passing through the first active mechanism 31 (which can be a cam) and the second active mechanism 41 (which can be a cam), the battery cell positioning mechanism 2 is firstly subjected to the reaction of the second active mechanism 41 due to the change in shape to open the flipping positioning, and then the force of the first active mechanism 31 reacting to the first driven mechanism 32 due to the change in shape can allow the battery cell positioning mechanism 2 to complete the flipping. In summary, the entire process of unlocking, flipping, positioning and flipping is continuous, and the clamp device 100 does not need to stop, thereby saving production time.

[0082] Furthermore, the locking member 433 is a locking pin, and the battery cell positioning mechanism 2 is provided with a locking groove, and the locking pin is locked with the locking groove. When the locking pin is locked with the locking groove, the rotation of the battery cell positioning mechanism 2 is restricted, and when the locking pin is separated from the locking groove, the battery cell positioning mechanism 2 can rotate normally, so as to facilitate the flipping of different surfaces of the battery cell 200. In summary, by selectively locking the locking member 433 on the rotating locking mechanism 4 with the locking groove on the battery cell positioning mechanism 2, the integrity of the unlocking and locking functions of the rotating locking mechanism 4 on the locking groove can be improved, thereby improving the practicality and scientificity of the rotating locking mechanism 4. The locking piece 433 on the rotating locking mechanism 4 selectively locks the locking groove on the battery cell positioning mechanism 2, which can also make the battery cell positioning mechanism 2 flip over more smoothly and normally when flipping, and can also avoid the problem of the battery cell positioning mechanism 2 swinging back and forth when the battery cell positioning mechanism 2 is in the same operation stage (that is, when there is no flipping requirement), thereby improving the position stability of the battery cell positioning mechanism 2 and ensuring processing accuracy.

[0083] Specifically, combined Figure 1 , Figure 2 and Figure 8 As shown, the rotation locking mechanism 4 also includes a first elastic member 42, which is arranged between the conveyor line matching seat 1 and the mounting seat 432 to provide an elastic force through the mounting seat 432 to reset the locking member 433 to a position locked with the battery cell positioning mechanism 2.

[0084] It can be understood that the first elastic member 42 can undergo elastic deformation to form an elastic reset force on the locking member 433 to reset it to the position locked with the battery cell positioning mechanism 2, and the direction of the elastic reset force is opposite to the direction of the extrusion force exerted on the mounting seat 432. When the second follower 431 moves from the protruding section on the first extrusion surface 411 toward the side of the second follower 431 to the recessed section on the first extrusion surface 411 toward the side of the second follower 431, the locking member 433 can achieve an automatic locking effect under the action of the elastic reset force.

[0085] For example, when the battery cell positioning mechanism 2 moves on the conveyor line, when passing through the first active mechanism 31 (which can be a cam) and the second active mechanism 41 (which can be a cam), it is first affected by the shape change of the second active mechanism 41, and the second follower 431 will follow the shape change of the second active mechanism 41 (cam). The second follower 431 will slowly move to the side close to the battery cell 200, and by squeezing the mounting seat 432, the mounting seat 432 will move together with the locking member 433 to the side close to the battery cell 200, and then the locking member 433 will separate from the locking groove, so that the rotation positioning of the battery cell positioning mechanism 2 can be opened. When the rotation positioning of the battery cell positioning mechanism 2 is fully opened When the first follower 321 is rotated, the first follower 321 will move along with the shape change of the first active mechanism 31, and the first follower 321 will slowly rotate. The first follower 321 will drive the driven disk 322 to rotate together, because the driven disk 322 is fixed on the battery cell positioning mechanism 2, so that the battery cell 200 can be rotated. After completing a 90° rotation, the first follower 321 and the second follower 431 will slowly separate from the first active mechanism 31 and the second active mechanism 41. At this time, the mounting seat 432 will be repositioned again to complete the secondary positioning of the battery cell positioning mechanism 2 after flipping, and the rotation angle can be corrected. The entire flipping process is completed by the clamp device 100 while it is moving, and it can realize the continuous self-flipping function. Moreover, by setting multiple first active mechanisms 31 and second active mechanisms 41 at intervals, the battery cell positioning mechanism 2 can continue to move forward to complete the next step of welding, and so on. Finally, the clamp completes the entire 0°, 90°, and 180° flipping, and finally completes the welding of the four sides of the battery cell 200.

[0086] Furthermore, combined with Figure 1 , Figure 2 and Figure 8As shown, the battery cell positioning mechanism 2 includes a battery cell positioning component 22 and a rotating component 23. The battery cell positioning component 22 is used to fix the battery cell 200. The rotating component 23 is rotatably arranged on the conveyor line matching seat 1, and the rotating component 23 is connected to the battery cell positioning component 22; wherein, at least one of the battery cell positioning component 22 and the rotating component 23 is provided with a first locking portion that is locked with the locking member 433.

[0087] For example, the rotating component 23 can be rotatably disposed on the conveyor line matching seat 1, and the rotating component 23 is provided with a first locking portion for locking with the locking piece 433. In this way, after the rotating component 23 is flipped at a specified angle along with the battery cell positioning mechanism 2, the first locking portion on the rotating component 23 can be locked with the locking piece 433, so that the battery cell positioning mechanism 2 can be locked, thereby ensuring the stability and accuracy of the battery cell positioning mechanism 2 in the locked position.

[0088] Specifically, the rotating assembly 23 is provided with a locker 231 on a side of the mounting seat 432 away from the conveyor line matching seat 1 , the locker 231 is arranged opposite to the mounting seat 432 , and the locker 231 is provided with a first locking portion.

[0089] It can be understood that, along the conveying direction perpendicular to the conveying line, the rotating component 23 is provided with a locker 231 on the side of the mounting seat 432 away from the conveying line matching seat 1, and the mounting seat 432 is provided with a second follower 431. When the second follower 431 comes into contact and cooperates with the first extrusion surface 411 with a changed size, the second follower 431 will drive the mounting seat 432 to passively shift, so that the locking member 433 on the mounting seat 432 can be moved, thereby realizing the locking and unlocking cooperation effect between the locking member 433 and the first locking part on the rotating component 23 through the movement of the locking member 433.

[0090] Furthermore, combined with Figure 7 As shown, the battery cell positioning assembly 22 is provided with a rotating positioning disk 221, and the rotating positioning disk 221 is connected to the mounting seat 432. The second locking portion 24 is provided on the rotating positioning disk 221, and the conveyor line matching seat 1 is provided with a fixer 25 on the side away from the battery cell 200. With such an arrangement, when the second follower 431 on the mounting seat 432 comes into contact and matches with the first extrusion surface 411 with a changed size, the second follower 431 will drive the mounting seat 432 to be passively displaced, so that the mounting seat 432 can drive the rotating positioning disk 221 to move, thereby realizing the locking and unlocking matching effect between the rotating positioning disk 221 and the fixer 25 through the movement of the second locking portion 24 on the rotating positioning disk 221, thereby realizing the control effect of the position state of the battery cell positioning mechanism 2.

[0091] Specifically, combined Figure 1 and Figure 3As shown, the battery cell positioning mechanisms 2 are respectively arranged at both ends of the conveyor line matching seat 1, at least one battery cell positioning mechanism 2 at the two ends corresponds to the rotation drive mechanism 3, and at least one battery cell positioning mechanism 2 at the two ends corresponds to the rotation positioning mechanism.

[0092] It can be understood that both ends of the conveyor line matching seat 1 are provided with a battery cell positioning mechanism 2, which can increase the number of positioning on different surfaces of the battery cell 200, thereby improving the positioning effect of the battery cell 200; and one end of the conveyor line matching seat 1 can be provided with a rotating drive mechanism 3, and the other end of the conveyor line matching seat 1 can be provided with a battery cell positioning mechanism 2, or one end or both ends of the conveyor line matching seat 1 can be provided with a battery cell positioning mechanism 2 and a rotating drive mechanism 3, thereby improving the flexibility of selection.

[0093] According to some optional embodiments of the present invention, Figure 1 , Figure 2 and Figure 6 As shown, the clamp device 100 further includes a clamping mechanism 5 , which is disposed on at least one side of the conveyor line matching seat 1 , and is used to selectively control the battery cell positioning mechanism 2 to release the positioning of the battery cell 200 .

[0094] Among them, the clamping mechanism 5 can selectively release and reposition the battery cell 200 according to different production requirements, thereby improving the automation effect in the production process, reducing manual operation time and human intervention, and further improving production efficiency.

[0095] In addition, when the length of the battery to be welded is relatively large, the positioning method of the clamp device 100 can be changed to double-sided positioning and double-sided flipping, thereby enhancing the rigidity and positioning accuracy of the clamp device 100.

[0096] As arranged above, the battery cell positioning mechanism 2 can complete the opening and clamping action during the movement before moving to the loading or unloading station. Then, after the battery cell positioning mechanism 2 reaches the loading and unloading station, the loading and unloading action can be completed immediately. Then, the battery cell positioning mechanism 2 continues to move and completes the closing and clamping action during the movement. Compared with the existing clamps, during the loading and unloading process of the clamp device 100, there is no need to wait for the clamp device 100 to stop in place, first open the clamp, then load and unload, and finally close the clamp and move away. The embodiment in this case can greatly shorten the total time for loading and unloading, and effectively improve the beat of the whole machine.

[0097] Specifically, combined Figure 1-Figure 3 and Figure 6As shown, the clamping mechanism 5 includes a third active mechanism 51 and a third driven mechanism. The third active mechanism 51 is spaced apart from the battery cell positioning mechanism 2, and the third driven mechanism is connected to the battery cell positioning mechanism 2. When the conveyor line matching seat 1 moves to a predetermined clamping position, the third driven mechanism cooperates with the third active mechanism 51, and the third driven mechanism drives the battery cell positioning mechanism 2 to release the positioning of the battery cell 200 under the action of the third active mechanism 51.

[0098] It is understandable that the cooperation between the third active mechanism 51 and the third driven mechanism can enable the clamping mechanism 5 to accurately release the fixation of the battery cell 200 by the battery cell positioning mechanism 2, so that the battery cell 200 can be removed or replaced, thereby improving the production efficiency of the production line.

[0099] Among them, when the clamp device 100 moves on the conveyor line (without passing through the third active mechanism 51), the third active mechanism 51 and the third driven mechanism are separated, the battery cell positioning mechanism 2 is in a locked state, and the battery cell 200 is firmly fixed in a predetermined position. When the conveyor line matching seat 1 moves to a predetermined opening position, the third active mechanism 51 and the third driven mechanism contact and cooperate, the third active mechanism 51 drives the third driven mechanism to move, and the third driven mechanism drives the battery cell positioning mechanism 2 to release the positioning of the battery cell 200, thereby facilitating the subsequent removal or replacement of the battery cell 200.

[0100] For example, the third active mechanism 51 can be an external cam groove structure, and the third driven mechanism can be a cam follower. As the cam follower moves, it can be pushed by the cam groove mechanism (that is, the outer cam track of the cam groove mechanism is used to push open the battery cell positioning mechanism 2 to position the battery cell 200) to achieve the follow-up clamping effect.

[0101] Furthermore, the third active mechanism 51 and the third driven mechanism are separately arranged, and the third active mechanism 51 is suitable for being located on one side of the conveyor line. Such an arrangement can facilitate the operator to perform separate maintenance and replacement of the third active mechanism 51 and one of the third driven mechanisms, and can also effectively utilize the space on one side of the conveyor line, thereby improving the assembly and disassembly flexibility of the clamping mechanism 5 and the rationality of the spatial layout.

[0102] Specifically, combined Figure 1-Figure 3 and Figure 6 As shown, the third active mechanism 51 is provided with a second extrusion surface 511 with variable size along a direction perpendicular to the conveying direction of the conveyor line, and the battery cell positioning assembly 22 is provided with a third follower 222; when the conveyor line matching seat 1 moves to a predetermined clamping position, the third follower 222 is suitable for contacting and matching with the second extrusion surface 511, and the third follower 222 moves relative to the conveyor line matching seat 1 under the action of the second extrusion surface 511, thereby driving the battery cell positioning mechanism 2 to release the positioning of the battery cell 200.

[0103] It can be understood that along the conveying direction perpendicular to the conveyor line, the position of the third active mechanism 51 is relatively fixed with the position of the conveyor line matching seat 1, and the third active mechanism 51 also forms a second extrusion surface 511 with variable size. The third follower 222 on the third driven mechanism can be passively shifted relative to the conveyor line matching seat 1 when it contacts and cooperates with the second extrusion surface 511, so that the battery cell positioning mechanism 2 can smoothly release the positioning of the battery cell 200, thereby improving the automatic opening and clamping effect of the battery cell positioning mechanism 2.

[0104] Furthermore, combined with Figure 1-Figure 3 and Figure 6 As shown, the second extrusion surface 511 includes a second raised section 5111 and a second recessed section 5112, the second raised section 5111 protrudes toward the side away from the conveyor line matching seat 1, the distance from the second recessed section 5112 to the second follower 431 is greater than the distance from the second raised section 5111 to the third follower 222, and the second recessed section 5112 is connected to both sides of the second raised section 5111.

[0105] Among them, when the second protrusion section 5111 is in contact and cooperate with the third follower 222, the third follower 222 moves relative to the battery cell positioning mechanism 2 toward away from the conveyor line matching seat 1, so that the third follower 222 drives the battery cell positioning mechanism 2 to move away from and release the fixed state of the battery cell 200. When the second recessed section 5112 is in contact and cooperate with the third follower 222, the third follower 222 moves relative to the battery cell positioning mechanism 2 toward the inner side of the conveyor line matching seat 1. At this time, the third follower 222 drives the battery cell positioning mechanism 2 to position the battery cell 200. In this way, the third follower 222 selectively contacts and cooperates with the second protrusion section 5111 or the second recessed section 5112, so that the battery cell positioning mechanism 2 can release and reposition the battery cell 200, thereby ensuring the position firmness and convenience of taking and placing the battery cell 200.

[0106] In addition, the second recessed section 5112 is connected to both sides of the second raised section 5111 , so that the battery cell positioning mechanism 2 can be in a fixed state before and after the battery cell 200 is released from the positioning process, thereby improving the position stability of the battery cell 200 at the same processing stage.

[0107] Specifically, the battery cell positioning mechanism 2 includes a battery cell positioning component 22 and a rotating component 23, the battery cell positioning component 22 is used to fix the battery cell 200, the rotating component 23 is rotatably arranged on the conveyor line matching seat 1, and the rotating component 23 is connected to the battery cell positioning component 22; wherein, the battery cell positioning component 22 includes a fixed seat 223, a short side positioner 224 and a long side positioner 225, the fixed seat 223 is connected to the rotating component 23, the short side positioner 224 is movably arranged on the fixed seat 223, and the short side positioner 224 positions the battery cell 200 in the length direction of the battery cell 200, the long side positioner 225 is movably arranged on the fixed seat 223, and the long side positioner 225 positions the battery cell 200 in the width direction of the battery cell 200, and at least one of the short side positioner 224 and the long side positioner 225 is connected to the third driven mechanism.

[0108] It can be understood that the short side locator 224 and the long side locator 225 can respectively position the battery cell 200 in the length and width directions of the battery cell 200, so as to ensure the position stability of the battery cell 200; and at least one of the short side locator 224 and the long side locator 225 is connected to the third driven mechanism. When the third driven mechanism contacts and cooperates with the third active mechanism 51, the third driven mechanism can drive the short side locator 224 and the long side locator 225 to move, so as to release the positioning state of the battery cell 200.

[0109] Specifically, combined Figure 10-13 As shown, the short side positioner 224 includes a short side pressure plate 2241, a short side sliding member 2242 and a fourth follower. The short side pressure plate 2241 is movably arranged on the fixed seat 223, and the short side pressure plate 2241 positions the battery cell 200 in the length direction of the battery cell 200. The short side sliding member 2242 is movably arranged on the fixed seat 223, and the short side sliding member 2242 is connected to the third driven mechanism. The short side sliding member 2242 is provided with a slope with varying height, and the height of the end of the slope away from the third active mechanism 51 is greater than the height of the end of the slope close to the third active mechanism 51. The fourth follower is connected to the short side pressure plate 2241, and the fourth follower cooperates with the slope guide. When the short side sliding member 2242 moves toward the side away from the battery cell 200 driven by the third follower 222, the fourth follower drives the short side pressure plate 2241 to move upward.

[0110] As arranged above, when the third driven mechanism contacts and cooperates with the third active mechanism 51, the third driven mechanism can drive the third follower 222 to move toward the side away from the battery cell 200 under the action of the third active mechanism 51, and the third follower 222 drives the short side sliding member 2242 to move along the length direction of the battery cell 200 toward the side away from the battery cell 200. At the same time, the fourth follower cooperates with the slope guide on the third follower 222. Under the action of the slope, the fourth follower drives the short side pressure plate 2241 to gradually move toward the upper side away from the battery cell 200, so that the short side pressure plate 2241 moves toward the outer side and the upper side away from the battery cell 200 at the same time, thereby ensuring that the clamping mechanism 5 can successfully release the positioning state of the battery cell 200.

[0111] Furthermore, the short side positioner 224 further includes a second elastic member, which is in contact between the base 512 and the short side sliding member 2242 to provide an elastic restoring force for the short side sliding member 2242 to move toward one side of the battery cell 200. The second elastic member can be elastically deformed to form an elastic restoring force on the short side sliding member 2242 to move it toward one side of the battery cell 200, and the direction of the elastic restoring force is opposite to the direction of the extrusion force on the third follower 222. When the third follower 222 moves from the protruding section on the second extrusion surface 511 toward one side of the third follower 222 to the concave section on the second extrusion surface 511 away from the third follower 222, the short side sliding member 2242 can achieve an automatic clamping effect under the action of the elastic restoring force.

[0112] Specifically, combined Figure 10-13 As shown, the long side positioner 225 includes a long side pressing plate 2251, a long side pull rod 2252 and a fifth follower 2253. The long side pressing plate 2251 is movably arranged on the fixed seat 223, and the long side pressing plate 2251 positions the battery cell 200 in the width direction of the battery cell 200. The long side pressing plate 2251 is connected to the long side pull rod 2252, and the long side pull rod 2252 is connected to the short side sliding member 2242. The long side pull rod 2252 is provided with a third extrusion surface with a variable size in the width direction of the battery cell 200, and the third extrusion surface is provided along the width direction of the battery cell 200. In the width direction, the distance from the side of the third extrusion surface away from the third follower 222 to the battery cell 200 is smaller than the distance from the side of the third extrusion surface close to the third follower 222 to the battery cell 200, the fifth follower 2253 cooperates with the slope guide, and the fifth follower 2253 is connected to the conveyor line matching seat 1. When the long side pull rod 2252 moves toward the direction away from the battery cell 200 driven by the short side sliding member 2242, the long side pressure plate 2251 moves in the direction away from the battery cell 200 under the action of the fifth follower 2253.

[0113] As arranged above, when the third driven mechanism contacts and cooperates with the third active mechanism 51, the third driven mechanism can drive the third follower 222 to move toward the side away from the battery cell 200 under the action of the third active mechanism 51, and the third follower 222 drives the short side sliding member 2242 to move toward the side away from the battery cell 200, and the short side sliding member 2242 drives the long side pull rod 2252 to move toward the side away from the battery cell 200, and the third extrusion surface on the long side pull rod 2252 is guided and cooperated with the fifth follower 2253. Under the action of the third extrusion surface, the fifth follower 2253 drives the long side pressure plate 2251 to gradually move along the width direction of the battery cell 200 toward the direction away from the battery cell 200, thereby making the long side pull rod 2252 move toward the outside away from the battery cell 200, thereby ensuring that the clamping mechanism 5 can successfully release the positioning state of the battery cell 200.

[0114] Furthermore, combined with Figure 6 As shown, the third active mechanism 51 includes a base 512, a top plate 513 and an active motor 514. The base 512 is suitable for being set on one side of the conveyor line. The top plate 513 is set on the top of the base 512, and the top plate 513 extends toward the direction of the adjacent conveyor line. The active motor 514 is set on the top plate 513, and the active motor 514 is used to contact and cooperate with the third driven mechanism.

[0115] Among them, the base 512 can serve as the main force-bearing support member of the third active mechanism 51, and can provide a stable support effect for the top plate 513 and the active device 514, thereby ensuring the stability of the entire third active mechanism 51 during operation; the top plate 513 is connected to the top of the base 512 and extends in the direction close to the conveyor line, thereby providing the active device 514 with an installation platform close to the third driven mechanism, so that the active device 514 can smoothly contact and cooperate with the third driven mechanism, thereby ensuring that the battery cell positioning mechanism 2 can smoothly release the fixed state of the battery cell 200.

[0116] For example, when the clamp device 100 moves on the conveyor line (without passing through the third active mechanism 51), the third active mechanism 51 and the third driven mechanism are separated, and the battery cell positioning mechanism 2 is in a state of locking the battery cell 200. At this time, the battery cell 200 is firmly fixed in a predetermined position. When the third driven mechanism moves to the predetermined unclamping position, the active device 514 on the third active mechanism 51 contacts and cooperates with the third driven mechanism, so that the battery cell positioning mechanism 2 releases the positioning of the battery cell 200 under the drive of the third driven mechanism.

[0117] Specifically, the active device 514 is configured as an active block, and a surface of one side of the active block adjacent to the base 512 is a second extrusion surface 511 with a variable size, and the second extrusion surface 511 is used for contacting and cooperating with the third driven mechanism.

[0118] It can be understood that, in the conveying direction perpendicular to the conveyor line, the third follower 222 on the third follower mechanism can be passively shifted relative to the conveyor line mating seat 1 when it contacts and cooperates with the second extrusion surface 511, so that the battery cell positioning mechanism 2 can smoothly release the positioning of the battery cell 200, thereby improving the automatic opening effect of the battery cell positioning mechanism 2.

[0119] For example, before the battery cell positioning mechanism 2 reaches the loading and unloading station, when the third driven mechanism (which can be a cam follower) passes through the third active mechanism 51 (which can be a cam), the cam trajectory of the cam of the third active mechanism 51 will squeeze the cam follower, and the cam follower will move toward the side away from the battery cell 200 under the action of the squeezing force, and the cam follower will drive the short side sliding member 2242 to move together when moving, and when the short side sliding member 2242 moves horizontally, it will lift the short side pressure plate 2241 through a slope of the part itself, and the upward movement of the short side pressure plate 2241 will complete the clamping of the long side of the battery cell 200, so that the positioning of the long side of the battery cell 200 can be opened; the movement of the short side sliding member 2242 will also drive the long side pull rod 2252, and the movement of the long side pull rod 2252 will pull the long side pressure plate 2251 to move toward the side away from the battery cell 200, so that the positioning of the short side of the battery cell 200 can be opened. Similarly, the closing of the battery cell positioning mechanism 2 is the reverse action logic of its opening, and the entire opening and closing process is completed by the battery cell positioning mechanism 2 during movement, with continuous movements, which can achieve continuous opening and closing, and effectively shorten the time for stopping to open and close the battery cell 200 due to the need to load and unload the battery cell 200.

[0120] Optionally, the active device 514 is constructed as a cylinder, which has the characteristics of fast response speed, simple structure and large thrust. The above arrangement can improve the clamping sensitivity and clamping ability of the clamping mechanism 5 and reduce the cost of use.

[0121] Alternatively, the active device 514 is constructed as a screw motor 312, which has the characteristics of high control accuracy and strong movement stability. The above arrangement can improve the accuracy and stability of clamping.

[0122] According to the second aspect of the present invention, the battery cell 200 production line includes a conveyor line and the clamp device 100 of the above embodiment, and the conveyor line matching seat 1 is arranged on the conveyor line. Thus, the battery cell 200 production line with the clamp device 100 can realize the non-carrying continuous operation of the production line (completing the required functional conversion during movement, such as switching clamps and flipping, etc.), thereby effectively shortening the total time of loading and unloading the conveyor line, and then effectively improving production efficiency.
