Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to a battery cell conveying fixture, battery processing equipment, and battery processing method. Background Technology

[0002] In the battery manufacturing process, transport fixtures are core components that connect various processes and ensure the stable transfer of semi-finished and finished batteries. Their performance directly affects the operating efficiency and product yield of the entire production line. Currently, traditional battery transport fixtures generally suffer from insufficient compatibility. Most fixtures can only adapt to a single battery model or a specific process station, failing to meet the needs of multi-model battery co-production and multi-station collaborative operation. Due to limited compatibility, battery transfer between different stations requires additional specialized robotic arms to perform gripping, handling, and positioning operations, which not only increases equipment investment costs but also prolongs process connection time. The starting, stopping, and positioning calibration actions of the robotic arms during handling significantly disrupt the continuous production cycle of the equipment. Summary of the Invention

[0056] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0057] The following is for reference. Figures 1-12 A conveying fixture 100 for a battery cell 600 according to a first aspect embodiment of the present invention is described. The conveying fixture 100 of this embodiment is used to convey the battery cell 600, which includes a battery body 610 and a top cover 620 covering the top of the battery body 610. The conveying fixture 100 of this embodiment can be used to convey the battery cell 600 before and after the top cover 620 is pressed into place. Thus, the battery cell 600 can be conveyed through the conveying fixture 100 of this embodiment in both the process before and after the top cover 620 is pressed into place, improving the versatility of the conveying fixture 100.

[0058] like Figures 1-4 As shown, a conveying fixture 100 for a battery cell 600 according to a first aspect embodiment of the present invention includes: a frame 10, a limiting component 20, and a clamping component 30. The frame 10 defines a clamping space 101 with an open top; the limiting component 20 is disposed on the frame 10 and includes a first limiting member 211 and a second limiting member 221, the first limiting member 211 being configured to limit the position of the battery body 610 in the vertical direction, and the second limiting member 221 being configured to limit the position of the battery body 610 in the horizontal plane; the clamping component 30 is disposed on the frame 10 and is used to clamp and release a top cover 620 located on top of the battery body 610.

[0059] like Figure 1 As shown, the frame 10 has a U-shaped shape with an open top. Specifically, the frame 10 includes a bottom frame and two side frames. The bottom frame is horizontally positioned and extends along a first direction (e.g., Figure 1 Extending in the left and right directions shown, the two side wall frames are respectively connected to the two ends of the bottom frame in the first direction and extend vertically upward. The bottom frame and the two side frames cooperate to define a clamping space 101. The battery cell 600 can be clamped in the clamping space 101 by the limiting component 20 and the clamping component 30.

[0060] In some examples, such as Figures 1-4As shown, the first limiting member 211 engages with the battery body 610 in the vertical direction to limit the movement of the battery body 610 in the vertical direction. The second limiting member 221 engages with the battery cell 600 in the first direction to limit the movement of the battery cell 600 in the first direction. The clamping assembly 30 is used to clamp and release the top cover 620 of the battery cell 600. When the clamping assembly 30 clamps the top cover 620, the relative position of the top cover 620 and the battery assembly is fixed. For example, before the top cover 620 is pressed in, the clamping assembly 30 can clamp the top cover 620 and make a certain gap between the top cover 620 and the battery body 610 to facilitate the subsequent pressing in of the top cover 620. After the top cover 620 is pressed in, the clamping assembly 30 can clamp the top cover 620 to keep the top cover 620 in the position after being pressed in, to prevent the top cover 620 from being squeezed out, and to facilitate the subsequent welding operation of the battery cell 600. When the clamping assembly 30 releases the top cover 620, the top cover 620 can move relative to the battery cell 600 under the action of external force. For example, the top cover 620 can be pressed into the battery body 610 under the action of the pressing mechanism 540.

[0061] For example, when the conveying fixture 100 of this embodiment is used to convey the battery cell 600, the battery body 610 before pressing can be placed into the clamping space 101 of the conveying fixture 100, and the battery body 610 can be limited and fixed by the limiting component 20. The top cover 620 is placed on the top of the battery body 610 and fixed by the clamping component 30. Then, the battery cell 600 is conveyed to the pressing station by the conveying fixture 100. At the pressing station, the top cover 620 can be released by the clamping component 30. This process does not interfere with the pressing process of the pressing mechanism 540 on the top cover 620. Therefore, the battery cell 600 can be directly transported to the pressing device 500 via the conveying fixture 100 and pressed on the conveying fixture 100 without the need for a robot to transfer it to the pressing device 500 for pressing. After pressing is completed, the conveying fixture 100 can clamp the top cover 620 again via the clamping component 30 to maintain the pressed state of the top cover 620. Then, the conveying fixture 100 can directly transport the battery cell 600 to the welding station. In this way, the conveying fixture 100 can be compatible with multiple stations. For example, the conveying fixture 100 can be compatible with at least the assembly station, pressing station, and welding station of the battery processing equipment 1000. Throughout the entire process, there is no need for robot handling operations, thereby avoiding affecting the production cycle of the battery processing equipment 1000 and improving the production efficiency of the battery processing equipment 1000.

[0062] According to the present invention, the conveying fixture 100 for the battery cell 600 limits the battery body 610 by setting a limiting component 20 and a clamping component 30 for clamping and releasing the top cover 620. This allows the conveying fixture 100 to be compatible with multiple workstations, enabling the battery cell 600 to be directly conveyed and processed between multiple workstations via the conveying fixture 100 without the need for robotic arm handling. As a result, the production cycle of the battery processing equipment 1000 can be avoided, and the production efficiency of the battery processing equipment 1000 can be improved.

[0063] In some embodiments of the present invention, such as Figures 5-8 As shown, the clamping assembly 30 may include: a first clamping mechanism 31, the first clamping mechanism 31 including a first clamping member 311, the first clamping member 311 having a first clamping portion 3111, the first clamping member 311 being movable relative to the frame 10 between a first clamping position and a first release position, in the first clamping position, the first clamping portion 3111 being located between the battery body 610 and the top cover 620, so that the top cover 620 and the battery body 610 are vertically separated, in the first release position, the first clamping portion 3111 being away from the battery cell 600.

[0064] By setting a first clamping mechanism 31 that can move between a first clamping position and a first release position, and by using the first clamping part 3111 to extend into the gap between the battery body 610 and the top cover 620 to form an upper and lower separation, relative squeezing and collision between the top cover 620 and the battery body 610 can be effectively avoided during transportation, ensuring the structural integrity and performance stability of the battery cell 600. At the same time, it can also prevent the top cover 620 from falling into the battery body 610, and prevent the top cover 620 from being installed in the battery body 610 in an offset or skewed posture, improving the posture consistency of the battery cell 600 during transportation, and improving the transportation efficiency and yield of the battery cell 600.

[0065] It should be noted that the first clamping mechanism 31 in this embodiment is used to clamp and fix the top cover 620 of the battery cell 600 when the conveying jig 100 conveys the battery cell 600 before the top cover 620 is pressed in.

[0066] In some embodiments of the present invention, such as Figures 6-8 As shown, the first clamping member 311 is along a first direction in the horizontal plane (e.g., Figure 6 The first clamping part 3111 is movable in the left and right directions shown in the figure. In the first clamping position, the first clamping part 3111 abuts against the side surface of the top cover 620 in the first direction. In the first release position, the first clamping part 3111 and the top cover 620 are spaced apart in the first direction.

[0067] By moving the first clamping member 311 along a horizontal first direction, the first clamping part 3111 abuts against the side surface of the top cover 620 at the first clamping position, thereby achieving horizontal limiting and positioning of the top cover 620. Simultaneously, since the first clamping part 3111 also acts as a vertical separator between the battery body 610 and the top cover 620, it effectively prevents the top cover 620 and the battery body 610 from rubbing or colliding due to shaking, preventing damage to the sealing structure and ensuring the posture stability and structural safety of the battery cell 600 during transportation.

[0068] like Figure 6 and Figure 12 As shown, the top cover 620 of the battery cell 600 includes a cover body and a boss portion arranged on the lower side of the cover body and extending toward the battery body 610. In the horizontal plane, the periphery of the cover body extends beyond the periphery of the boss portion. When the top cover 620 is assembled with the battery body 610, the boss portion extends into and engages with the battery body 610. When the first clamping member 311 is in the first clamping position, the first clamping part 3111 is clamped between the cover body and the battery body 610, and the first clamping part 3111 abuts against the side surface of the boss portion. Thus, the first clamping part 3111 can engage with the periphery of the cover body in the vertical direction to prevent the top cover 620 from falling into the battery body 610. At the same time, the first clamping part 3111 can also clamp the boss portion in the first direction to achieve the clamping effect on the top cover 620 and prevent the top cover 620 from shaking, shifting, or falling off the conveying fixture 100.

[0069] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the first clamping member 311 further includes a second clamping part 3112, which extends in the vertical direction. The first clamping part 3111 is connected to the upper end of the second clamping part 3112 and extends in the first direction toward the center of the clamping space 101. In the first clamping position, the second clamping part 3112 abuts against the side surface of the battery body 610 in the first direction to clamp the battery body 610. Thus, the second clamping part 3112 can achieve vertical limiting and horizontal clamping of the battery body 610, and can also cooperate with the first clamping part 3111 to form a layered clamping and positioning of the battery body 610 and the top cover 620 of the battery cell 600, effectively preventing horizontal displacement and tipping during transportation, avoiding collision and friction between the top cover 620 and the battery body 610, and improving transportation stability.

[0070] In some examples, such as Figure 7As shown, a buffer is provided on the side of the second clamping part 3112 facing the battery cell 600. This buffer, with its elastic deformation capability, effectively cushions the rigid impact between the battery body 610 and the second clamping part 3112 during transport, preventing mechanical damage to the battery casing surface. Simultaneously, the buffer increases contact friction, making the clamping more stable and preventing the battery cell 600 from slipping or shifting during transport, further improving the clamping reliability and safety of the transport fixture 100.

[0071] In some embodiments of the present invention, such as Figure 6 and Figure 11 As shown, the first clamping mechanism 31 may further include a first elastic member 312, which extends along a first direction and is connected between the first clamping member 311 and the frame 10. The first elastic member 312 is used to push the first clamping member 311 toward the first clamping position. For example, the first elastic member 312 may always have a force that pushes the first clamping member 311 toward the first clamping position. When the first clamping member 311 moves from the first clamping position toward the first release position, it can push the first elastic member 312 to undergo elastic deformation. When the external force acting on the first clamping member 311 disappears, the first elastic member 312 restores its deformation and pushes the first clamping member 311 from the first release position toward the first clamping position. In this embodiment, by utilizing the elastic force of the first elastic member 312 to continuously push the first clamping member 311 toward the first clamping position, adaptive elastic clamping of the battery cell 600 can be achieved. This not only compensates for the dimensional tolerances of the battery cell 600 and ensures that battery cells 600 of different specifications can be firmly clamped, but also avoids deformation of the battery cell 600 shell caused by excessive rigid clamping force. At the same time, the first elastic member 312 can also provide continuous buffering during transport vibration.

[0072] In some examples, such as Figure 6 and Figure 11 As shown, the first elastic element 312 is a spring, and there are multiple first elastic elements 312 arranged at intervals. For example, there can be three first elastic elements 312. The multiple first elastic elements 312 can extend along a first direction and be arranged at intervals in a second direction. The multiple first elastic elements 312 can not only evenly distribute the elastic thrust to different force-bearing positions of the first clamping member 311, avoiding local stress concentration, but also provide a more stable and continuous clamping force, effectively improving the clamping reliability of the battery cell 600.

[0073] In some embodiments of the present invention, such as Figure 6 and Figure 11As shown, the first clamping mechanism 31 further includes a connector 313 extending along a first direction. A first clamping member 311 is fixed to one end of the connector 313 facing the battery cell 600, and a first elastic member 312 is connected between the other end of the connector 313 and the frame 10. By providing the connector 313 between the first clamping member 311 and the first elastic member 312, the connector 313 can achieve uniform transmission of the elastic force of the first elastic member 312, avoiding local force imbalance that could lead to clamping deviation. The connector 313 can also improve the straightness of the movement of the first clamping member 311, ensuring accurate clamping position.

[0074] In some embodiments of the present invention, such as Figure 6 and Figure 11 As shown, the connector 313 includes a guide rod portion 3131 extending along a first direction. A guide cylinder 11 is provided on the frame 10, and the guide rod portion 3131 is slidably fitted into the guide cylinder 11 along the first direction. In this embodiment, the sliding engagement between the guide rod portion 3131 and the guide cylinder 11 on the frame 10 provides precise guidance for the movement of the connector 313 and the first clamping member 311, ensuring that the first clamping member 311 moves linearly along the first direction and avoiding skewing or jamming, thus ensuring that the first clamping member 3111 can be accurately inserted into the gap between the battery body 610 and the top cover 620.

[0075] In some examples, such as Figure 6 and Figure 11 As shown, there are multiple guide rods 3131, which are spaced apart in the second direction. There are also multiple guide cylinders 11, each corresponding to one of the guide rods 3131. This further improves the guiding accuracy and stability of the first clamping member 311 moving along the first direction, and more effectively avoids the problem of the guide rods 3131 becoming misaligned or stuck. For example... Figure 11 As shown, the connector 313 includes a connecting rod portion and two guide rod portions 3131. The connecting rod portion extends in a rod shape along a second direction. The two guide rod portions 3131 are connected to the side of the connecting rod portion facing the first clamping member 311 in a first direction and are spaced apart in the second direction. The guide rod portions 3131 are perpendicular to the connecting rod portion. A plurality of first elastic members 312 are arranged on the side of the connecting rod portion away from the guide rod portions 3131 and are spaced apart along the length direction of the connecting rod portion. The other end of the plurality of first elastic members 312 is fixedly connected to the frame 10.

[0076] In some embodiments of the present invention, such as Figure 6 and Figure 11As shown, the first clamping mechanism 31 further includes a first pushing member 314, which is configured to push the first clamping member 311 from the first clamping position toward the first release position. When it is necessary to release the top cover 620, the first pushing member 314 can actively push the first clamping member 311 from the first clamping position to the first release position. Then, under the elastic force of the first elastic member 312, the first clamping member 311 can automatically return to the first clamping position, thereby improving the clamping and release efficiency of the top cover 620 of the battery cell 600. In some examples, the first pushing member 314 can be a drive cylinder, or it can be a drive handle, drive rod, or drive knob, etc.

[0077] In some embodiments of the present invention, such as Figure 6 and Figure 11 As shown, the first pushing member 314 is movable along the second direction. The first pushing member 314 has a driving protrusion 3141, and the connecting member 313 has a mating protrusion 3132. A driving inclined surface 3142 is provided on the side of the driving protrusion 3141 facing the mating protrusion 3132. The driving inclined surface 3142 is inclined relative to the first and second directions. The driving protrusion 3141 pushes the mating protrusion 3132 to move along the first direction via the driving inclined surface 3142. When it is necessary to release the battery cell 600, the first pushing member 314 moves along the second direction, and the driving protrusion 3141 on it moves accordingly. When the driving ramp 3142 of the driving protrusion 3141 contacts the mating protrusion 3132 on the connector 313, the guiding effect of the ramp is used to convert the movement of the first pushing member 314 along the second direction into the movement of the connector 313 along the first direction, thereby overcoming the elastic force of the first elastic member 312 and pulling the first clamping member 311 from the first clamping position to the first release position, thereby releasing the battery cell 600.

[0078] In this embodiment, by having the driving inclined surface 3142 of the driving protrusion 3141 cooperate with the mating protrusion 3132, the movement of the first pushing member 314 along the second direction can be converted into the movement of the first clamping member 311 along the first direction, thereby realizing the reversal of the movement direction. As a result, a stable driving force can be provided to the first clamping member 311, ensuring that the first clamping member 311 can quickly and smoothly detach from the battery cell 600. It can also simplify and compact the overall structure, avoid interference between the first pushing member 314 and the first clamping member 311 moving on the same axis, and improve operational reliability.

[0079] like Figure 11 As shown, the connector 313 includes a connecting rod portion and two guide rod portions 3131, the connecting rod portion being along a second direction (e.g., Figure 11 Extending in the front-to-back direction shown in the diagram, two guide rods 3131 are connected to the two ends of the connecting rod and extend along the first direction (as shown in the diagram). Figure 11 Extending in the left-right direction shown, the connector 313 also includes a mounting block. The mounting block is connected to the connecting rod portion and arranged on the side of the connecting rod portion facing the first clamping member 311. The mounting block is located between the two guide rod portions 3131, and a mating protrusion 3132 is provided on the mounting block. Further, the mating protrusion 3132 is provided on the upper side of the mounting block, and the mating protrusion 3132 is formed as a cam. The axis of the cam is vertically arranged, and the cam is rotatably mounted on the mounting block.

[0080] Furthermore, such as Figure 11 As shown, the first pusher 314 extends in the shape of a rod along the second direction. The cross-section of the first pusher 314 perpendicular to the second direction can be rectangular. The first pusher 314 is arranged on the upper side of the connector 313 and is located between the connecting rod and the first clamping member 311. The side surface of the first pusher 314 facing the connecting rod is provided with a protruding driving protrusion 3141. The driving protrusion 3141 is arranged on the rear side of the mating protrusion 3132. The front surface of the driving protrusion 3141 is formed with a driving inclined surface 3142. In the direction from the first clamping member 311 toward the connector 313, the driving inclined surface 3142 extends backward in a direction that gradually moves away from the mating protrusion 3132.

[0081] In some embodiments of the present invention, such as Figure 6 and Figure 11 As shown, the first pushing member 314 is movable along a second direction between a first position and a second position. The first clamping mechanism 31 further includes a first stop 315 and a second stop 316. When the first pushing member 314 is in the first position, it is limited and abuts against the first stop 315. When the first pushing member 314 is in the second position, it is limited and abuts against the second stop 316. By setting the first stop 315 and the second stop 316, the movement limit position of the first pushing member 314 can be effectively limited, avoiding problems such as mechanism collisions caused by overtravel and overload failure of the first elastic member 312, and ensuring that the first pushing member 314 moves precisely to the correct position each time.

[0082] like Figure 11 As shown, the first pusher 314 extends in the second direction into a rod shape. The first pusher 314 has a first boss and a second boss protruding towards the first clamping member 311 at both ends in the second direction. The first stop member 315 and the second stop member 316 are arranged at intervals in the second direction and are arranged between the first boss and the second boss. When the first pusher 314 is in the first position, the first boss and the first stop member 315 abut in the second direction. When the first pusher 314 is in the second position, the second boss and the second stop member 316 abut in the second direction.

[0083] In some embodiments of the present invention, such as Figure 6 and Figure 7As shown, there are two first clamping mechanisms 31, which are arranged opposite to each other in the first direction. In the initial state, the first elastic members 312 of the two first clamping mechanisms 31 synchronously push the corresponding first clamping members 311 to move towards each other to the first clamping position, so that the first clamping parts 3111 on both sides extend into the gap between the battery body 610 and the top cover 620 and abut against the side of the top cover 620. The second clamping parts 3112 simultaneously clamp the two sides of the battery body 610, thereby realizing bidirectional clamping of the battery cell 600.

[0084] This embodiment, by arranging two first clamping mechanisms 31 opposite to each other in the first direction, can form a symmetrical bidirectional clamping of the battery cell 600, ensuring that the battery cell 600 is subjected to uniform force and avoiding posture displacement or local compression damage caused by unilateral clamping. At the same time, the bidirectional elastic clamping structure can adapt to the dimensional tolerances of battery cells 600 of different specifications, improving the versatility and stability of clamping.

[0085] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the clamping assembly 30 includes a second clamping mechanism 32, which includes a second clamping member 321. The second clamping member 321 has an abutment portion 3211. The second clamping member 321 is rotatable relative to the frame 10 between a second clamping position and a second release position. In the second clamping position, the abutment portion 3211 is located on the upper side of the top cover 620 and abuts against the top cover 620 in the vertical direction. In the second release position, the abutment portion 3211 is away from the top cover 620. By providing the rotatable second clamping member 321, in the second clamping position, the abutment portion 3211 can abut against and fit against the upper surface of the top cover 620, effectively restricting the vertical movement of the battery cell 600, preventing the top cover 620 from separating from the battery body 610, and preventing problems such as the top cover 620 becoming loose due to equipment bumps and start-stop impacts during transportation.

[0086] It should be noted that the second clamping mechanism 32 in this embodiment can be used to press the top cover 620 against the top of the battery body 610 after the top cover 620 is press-fitted, so as to prevent the top cover 620 from detaching from the battery body 610, and facilitate the delivery of the press-fitted battery cell 600 to the welding station, ensuring the normal and smooth operation of subsequent processes of the battery processing equipment. In addition, after the top cover 620 is pressed onto the top of the battery body 610, the second clamping mechanism 32 can press against the upper surface of the top cover 620 through the abutment portion 3211 of the second clamping member 321. The first clamping portion 3111 of the first clamping member 311 of the first clamping mechanism 31 can also press against the upper surface of the top cover 620, and the second clamping portion 3112 of the first clamping member 311 can press against the side of the battery body 610. In this way, the first clamping member 311 and the second clamping member 321 can work together to clamp the pressed battery cell 600, improve the clamping and fixing effect of the battery cell 600, and further prevent the battery cell 600 from being displaced or damaged during transportation.

[0087] In some embodiments of the present invention, such as Figure 3 , Figure 4 and Figure 9 As shown, the second clamping mechanism 32 further includes a clamping seat 322 and a push-pull member 323. The clamping seat 322 is located on the top of the frame 10. The second clamping member 321 is rotatably connected to the clamping seat 322 about a horizontally extending first axis. The push-pull member 323 is located on the clamping seat 322 and is used to drive the second clamping member 321 to rotate between a second clamping position and a second release position. For example, after the top cover 620 and the battery body 610 are press-fitted together, the push-pull member 323 drives the second clamping member 321 to rotate from the second release position to the second clamping position, so that the abutting part 3211 of the second clamping member 321 presses against the upper surface of the top cover 620. When the battery cell 600 is transported to the welding station, when welding the top cover 620 and the battery body 610, the push-pull member 323 can drive the second clamping member 321 to rotate from the second clamping position to the second release position, so as to facilitate the welding operation of the top cover 620 and the battery body 610 at the welding station and avoid the second clamping mechanism 32 from obstructing the welding head of the welding device. In this embodiment, by setting the push-pull member 323 to drive the second clamping member 321 to rotate, the second clamping member 321 can be quickly and smoothly switched between the second clamping position and the second release position, ensuring the reliability of clamping the battery cell 600 and the smoothness of release. In some examples, the push-pull component 323 can be an automatic drive structure such as a drive cylinder or an electric push rod. The push-pull component 323 can also be a drive handle, a drive knob, or an operating lever.

[0088] In some embodiments of the present invention, such as Figure 7 , Figure 9 and Figure 10As shown, the push-pull member 323 is movably mounted on the clamping base 322 in the vertical direction. The push-pull member 323 has a pushing part 3231, and the second clamping member 321 has a driven part 3212 that is in transmission cooperation with the pushing part 3231. The pushing part 3231 drives the second clamping member 321 to rotate through the driven part 3212. By movably mounting the push-pull member 323 on the clamping base 322 in the vertical direction, interference between the movement trajectory of the push-pull member 323 and other structures can be avoided. Simultaneously, the linear reciprocating motion of the push-pull member 323 can be converted into the rotational motion of the second clamping member 321 around a horizontal first axis through the transmission cooperation between the pushing part 3231 and the driven part 3212, enabling rapid switching between the second clamping position and the second release position, thus improving the driving efficiency of the second clamping member 321.

[0089] In some embodiments of the present invention, such as Figure 9 and Figure 10 As shown, the pushing part 3231 is formed as a pushing groove, at least a portion of which extends along an arc. The driven part 3212 is a horizontally extending protrusion that slidably fits within the pushing groove. In this embodiment, by setting the pushing part 3231 as a pushing groove and the driven part 3212 as a protrusion, jamming and interference problems during transmission can be avoided, improving the smoothness of the rotation of the second clamping member 321. It also simplifies the structure of the pushing part 3231 and the driven part 3212, reducing the number of parts, resulting in a compact structure, reduced space occupation, and lower production and maintenance costs. Furthermore, the pushing groove can limit the movement of the protrusion, restricting the rotation trajectory of the second clamping member 321. This eliminates the need for an additional limiting structure for the second clamping member 321, enabling precise rotation of the second clamping member 321.

[0090] In some embodiments of the present invention, such as Figure 9 and Figure 10 As shown, the pushing part 3231 includes a first groove segment 32311, a second groove segment 32312, and a third groove segment 32313 connected sequentially along the extending direction of the pushing part 3231. The first groove segment 32311 extends horizontally. The second groove segment 32312 is connected to one end of the first groove segment 32311 facing the clamping space 101 and extends downward along an arc. The third groove segment 32313 is connected to the lower end of the second groove segment 32312 and extends downward. The pushing member is movable between a third position and a fourth position in the vertical direction, with the third position located above the fourth position. The pushing groove is arranged on the side of the second clamping member 321 facing the battery cell 600 along its horizontal rotation axis. When the pushing member is in the third position, the protrusion engages within the third groove segment 32313, and the second clamping member 321 is in the second clamping position. When the pushing member is in the fourth position, the protrusion engages within the first groove segment 32311, and the second clamping member 321 is in the second release position.

[0091] In this embodiment, by including a first groove segment 32311, a second groove segment 32312, and a third groove segment 32313 in the pushing part 3231, the protrusion can be fitted into the pushing groove to drive the second clamping member 321 to rotate, which further simplifies the structure of the pushing part 3231 and facilitates the processing and manufacturing of the pushing part 3231.

[0092] In this embodiment, in the initial state, the second clamping mechanism 32 has the second clamping member 321 in the second release position, with the protrusion located in the horizontal first groove segment 32311 and the abutment portion 3211 away from the top cover 620. When it is necessary to clamp the top cover 620, the push-pull member 323 moves upward in the vertical direction, driving the push groove to move upward synchronously. The protrusion first slides along the horizontal first groove segment 32311, and then the protrusion enters the downward-extending arc-shaped second groove segment 32312. Under the guidance of the groove wall, the second clamping member 321 is driven to rotate around the horizontal first axis, and the abutment portion 3211 gradually flips towards the top cover 620. When the protrusion slides to the vertically downward third groove segment 32313, the abutment portion 3211 precisely fits the upper side of the top cover 620 and forms a vertical abutment, and the second clamping member 321 is stabilized in the second clamping position. When the top cover 620 needs to be released, the push-pull member 323 moves downward in the vertical direction, pushing the groove downward in sync. The protrusion first slides upward along the vertical third groove segment 32313, disengaging from the locked state; then it enters the arc-shaped second groove segment 32312 and slides in the opposite direction, causing the second clamping member 321 to rotate in the opposite direction, and the abutting part 3211 gradually moves away from the top cover 620; finally, the protrusion returns to the horizontal first groove segment 32311, and the second clamping member 321 resets to the second release position, completing one clamping and release action cycle.

[0093] In some embodiments of the present invention, such as Figure 9 and Figure 10 As shown, the second clamping mechanism 32 is arranged on one side of the clamping space 101 in the first direction. The push-pull member 323 includes two first vertical plates 3232 arranged opposite each other in the second direction. The second clamping member 321 is disposed between the two first vertical plates 3232. The push-pull member 323 is provided with two pushing parts 3231, which are respectively disposed on the two first vertical plates 3232. The driven part 3212 and the pushing part 3231 are correspondingly engaged. In this embodiment, by setting two first vertical plates 3232 and providing pushing parts 3231 on both first vertical plates 3232, the second clamping member 321 can be subjected to uniform force in the second direction, avoiding skewness and jamming caused by unilateral drive and reducing the failure rate.

[0094] In some embodiments of the present invention, such as Figure 9 and Figure 10As shown, the push-pull member 323 includes a second vertical plate 3233 extending vertically. The second vertical plate 3233 is arranged on the side of the second clamping member 321 away from the clamping space 101 and is connected between the two first vertical plates 3232. The second vertical plate 3233 can enhance the overall structural rigidity of the push-pull member 323. The second vertical plate 3233 can also be connected to the two first vertical plates 3232 in a U-shaped structure, and enclose the end of the second clamping member 321 connected to the clamping seat 322 within it, thereby improving the stability of the push-pull member 323's vertical movement and compacting the overall structure of the second clamping mechanism 32.

[0095] In some examples, such as Figure 9 As shown, the clamping base 322 includes a base body and a hinge post. The base body is a horizontally arranged plate shape and has a rectangular shape. The hinge post is connected to the upper surface of the base body and extends upward. One end of the second clamping member 321 includes two connecting ears. The two connecting ears are respectively arranged on opposite sides of the hinge post in the second direction and are rotatably connected to the hinge post through a hinge shaft. The protrusion is provided on the side of the two connecting ears that are opposite to each other in the second direction, and the protrusion is spaced apart from the axis of the hinge shaft.

[0096] In some examples, such as Figure 9 As shown, a guide rail is provided on the side of the hinge column opposite to the battery cell 600. The guide rail extends in the vertical direction. A sliding block is fixed on the side of the second vertical plate 3233 facing the hinge column. The sliding block is slidably mounted on the guide rail. Thus, the guide rail can guide the vertical movement of the push-pull member 323, improving the stability of the vertical movement of the push-pull member 323.

[0097] In some embodiments of the present invention, such as Figure 9 and Figure 10 As shown, the push-pull member 323 is provided with a clamping handle 3234, and the clamping handle 3234 has clamping grooves 3235 on opposite sides in the second direction. An external driving structure (such as the clamping mechanism 532 described below) can clamp the clamping handle 3234, thereby driving the push-pull member 323 to move up and down, and switching the position of the second clamping member 321. In some examples, the clamping handle 3234 is a plate shape that extends vertically. For example, the upper end of the clamping handle 3234 can be I-shaped, and the clamping grooves 3235 are recessed on opposite sides of the clamping handle 3234 in the second direction.

[0098] In some examples, the clamping handle 3234 can be integrally formed with the push-pull member 323, or the clamping handle 3234 and the push-pull member 323 can be separate parts, and the clamping handle 3234 and the push-pull member 323 can be detachably connected by fasteners.

[0099] In some embodiments of the present invention, such as Figure 10As shown, the second clamping member 321 further includes an extension rod 3213, one end of which is rotatably connected to the clamping seat 322, and an abutment portion 3211 is disposed at the other end of the extension rod 3213 and fixed to the side of the extension rod 3213 facing the clamping space 101 in the rotation direction. In this embodiment, by providing the extension rod 3213, the distance between the abutment portion 3211 and the rotation axis of the second clamping member 321 can be increased, allowing the abutment portion 3211 to generate a large abutment displacement with a small stroke of the push-pull member 323, ensuring that the abutment portion 3211 quickly reaches its position. Simultaneously, when the second clamping member 321 rotates towards the second release position, the abutment portion 3211 can rotate outward synchronously with the extension rod 3213, moving away from the top cover 620 to the maximum extent possible, thereby providing sufficient operating space for the battery cell 600 and effectively preventing interference and collision.

[0100] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, there are two second clamping mechanisms 32, which are arranged opposite to each other in the first direction. By arranging the second clamping mechanisms 32 on opposite sides of the battery cell 600, a symmetrical vertical clamping can be formed on the top cover 620 of the battery cell 600, so that the top cover 620 is subjected to uniform force and avoids problems such as tilting and deformation of the top cover 620 caused by unilateral contact.

[0101] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the limiting assembly 20 includes a first limiting mechanism 21, which includes a positioning plate 212 and a first limiting member 211. The positioning plate 212 is arranged within the clamping space 101, and the first limiting member 211 is fixed to the upper surface of the positioning plate 212. The positioning plate 212 is configured to position the conveying fixture 100 in the vertical direction. For example, the positioning plate 212 can be a horizontally arranged flat plate, and the first limiting member 211 is arranged on the upper surface of the positioning plate 212 and fixedly connected to the positioning plate 212.

[0102] When the conveying fixture 100 is delivered to the pressing station or welding station, the pressing device 500 or the welding device can position the conveying fixture 100 in the current position through the positioning plate 212, thereby achieving vertical positioning of the conveying fixture 100 and the pressing device 500 or the welding device. This facilitates pressing and welding operations on the battery cell 600 directly on the conveying fixture 100 without removing the battery cell 600, avoiding disruption to the production cycle and improving production efficiency.

[0103] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, a first limiting member 211 is arranged at the bottom of the clamping space 101. The battery body 610 is adapted to be supported on the upper surface of the first limiting member 211. The upper surface of the first limiting member 211 is provided with two first limiting ribs 2111 extending along a first direction. The two first limiting ribs 2111 are spaced apart in a second direction and are adapted to limit and cooperate with the two side surfaces of the battery body 610 in the second direction. The upper surface of the first limiting member 211 can restrict the position of the battery body 610 in the vertical direction, and the two first limiting ribs 2111 can restrict the position of the battery cell 600 in the second direction. Thus, the first limiting member 211 can limit the battery body 610 in both the vertical and second directions, effectively preventing the battery cell 600 from shaking, tilting, or tipping over during the transport process of the transport fixture 100. In addition, the two first limiting ribs 2111 can also prevent the battery body 610 from falling off the first limiting member 211 along the second direction, improving the reliability of fixing the battery cell 600.

[0104] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the first limiting mechanism 21 further includes a first buffer member 213, which is connected between the positioning plate 212 and the frame 10. For example, the first buffer member 213 can be a spring, and there can be multiple first buffer members 213 arranged at intervals on the horizontal plane. The first buffer member 213 is configured to buffer the vertical direction between the positioning plate 212 and the frame 10. For example, when the pressing mechanism 540 presses the top cover 620, the first buffer member 213 can buffer the downward impact force of the pressing head 541 of the pressing mechanism 540 on the battery cell 600 to a certain extent. In this embodiment, by setting the first buffer member 213 between the positioning plate 212 and the frame 10, the impact load generated by the start-up and stop of the equipment and the bumps during the transportation process can be effectively buffered, meeting the transportation needs under different working conditions.

[0105] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the first limiting mechanism 21 may further include: a first slide rail 214 and a mounting base 215. The first slide rail 214 extends along a first direction and is fixed to the frame 10. The mounting base 215 is disposed on the first slide rail 214 and its relative position to the first slide rail 214 along the first direction is adjustable. The positioning plate 212 is fixed on the mounting base 215. By adjusting the position of the mounting base 215 in the first direction, the positions of the positioning plate 212 and the first limiting member 211 in the first direction can be adjusted. Thus, the position of the first limiting member 211 can be adjusted according to the model and size of different battery cells 600, so that the conveying fixture 100 can be used for conveying different models of battery cells 600.

[0106] In some examples, such as Figure 2 As shown, the first buffer 213 is a spring extending in the vertical direction. There are multiple first buffers 213, and all of them are connected between the mounting base 215 and the positioning plate 212. This provides a uniform buffering force to the positioning plate 212 and the first limiting member 211 in the horizontal plane, improving the uniformity of force on the battery cell 600.

[0107] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the limiting component 20 may include a second limiting mechanism 22, which includes two second limiting members 221. The two second limiting members 221 are arranged opposite to each other in the first direction and cooperate with each other to clamp the battery body 610 in the first direction. By setting two second limiting members 221 to achieve bidirectional clamping of the battery body 610 in the first direction, the displacement of the battery body 610 in the first direction can be effectively limited, effectively preventing the battery cell 600 from moving around on the conveying fixture 100, and improving the stability and reliability of the conveying of the battery cell 600.

[0108] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the second limiting mechanism 22 further includes a second elastic member 222, which extends along a first direction, and at least one second limiting member 221 is connected to the frame 10 via the second elastic member 222. For example, only one second limiting member 221 may be connected to the frame 10 via the second elastic member 222, or both second limiting members 221 may be connected to the frame 10 via the second elastic member 222. In this case, one second limiting member 221 may be connected to the frame 10 via one or more second elastic members 222.

[0109] When it is necessary to clamp the battery cell 600, the second limiting member 221 can be pushed along the second direction to cause the second elastic member 222 to elastically deform. Then, the battery cell 600 is placed between the two second limiting members 221. Afterward, the second limiting members 221 are released, at which point the second elastic member 222 returns to its original deformation and pushes the second limiting members 221 to clamp the battery body 610 in the first direction. This not only provides a flexible clamping force for the battery cell 600 to fix the battery body 610 and avoids surface damage to the rigidly clamped battery cell 600, but also makes the conveying fixture 100 suitable for conveying battery cells 600 of different sizes, thus expanding the applicability of the conveying fixture 100. In addition, it makes the loading operation of the battery body 610 by the conveying fixture 100 simpler, more convenient and faster.

[0110] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the second limiting mechanism 22 further includes a second slide rail 223 and a sliding seat 224. The second slide rail 223 extends along the first direction and is disposed on the frame 10. The sliding seat 224 is slidably disposed on the second slide rail 223. A second elastic member 222 is connected between the sliding seat 224 and the frame 10. A second limiting member 221 is disposed on the sliding seat 224. When the second limiting member 221 moves along the second direction, the second limiting member 221 can guide the sliding seat 224 to move along the second direction. Since the sliding seat 224 is slidable along the second slide rail 223, the second slide rail 223 can guide the movement of the sliding seat 224 along the second direction, and thus guide the movement of the second limiting member 221 along the second direction. Therefore, the problem of the second limiting member 221 shifting or jamming can be avoided, ensuring the clamping and alignment accuracy of the two second limiting members 221 in the first direction.

[0111] In some embodiments of the present invention, such as Figure 5 As shown, the sliding seat 224 is provided with an opening clamping protrusion 2241, which is a cam. The cam is rotatably mounted on the sliding seat 224 along a vertically extending axis. The battery processing equipment 1000 may be provided with an opening clamping drive mechanism, which includes an opening clamping push rod and an opening clamping drive member. The opening clamping drive member is connected to the opening clamping push rod and is used to drive the opening clamping push rod to move. The opening clamping push rod is configured to abut against the opening clamping protrusion 2241 so as to push the sliding seat 224 to move along the first direction through the opening clamping protrusion 2241, thereby increasing the distance between the two second limiting members 221 of the second limiting mechanism 22. This facilitates the placement of the battery cell 600 between the two second limiting members 221, thereby achieving the positioning and clamping of the battery cell 600. As a result, the battery cell 600 can be automatically loaded into the conveying fixture 100, improving production efficiency.

[0112] In some embodiments of the present invention, such as Figure 3 As shown, the frame 10 is provided with a third slide rail 12 extending in the vertical direction. The second limiting member 221 is slidably disposed on the third slide rail 12 in the vertical direction. The second limiting mechanism 22 also includes a second buffer member 225 and a buffer support 226. The buffer support 226 is connected to the frame 10 and arranged vertically with the second limiting member 221. The second buffer member 225 is connected between the buffer support 226 and the second limiting member 221. When the conveying fixture 100 or the battery cell 600 is subjected to a force in the vertical direction, the second buffer member 225 can play a buffering role. For example, when the pressing mechanism 540 presses the top cover 620, the second buffer member 225 can buffer the downward impact force of the pressing head 541 of the pressing mechanism 540 on the battery cell 600 to a certain extent. In addition, the second buffer member 225 can also effectively buffer the impact load generated by the start-up and shutdown of the equipment and the bumps during the conveying process, meeting the conveying requirements under different working conditions.

[0113] In addition, in this embodiment, by setting a third slide rail 12 and slidably setting the second limiting member 221 on the third slide rail 12, the third slide rail 12 can guide the up and down movement of the second limiting member 221, avoid the battery cell 600 from tilting or shifting, and ensure that the pressing mechanism 540 can press the top cover 620 vertically downward.

[0114] like Figure 3 As shown, the second positioning mechanism 520 includes two second limiting members 221, and the second buffer member 225, buffer support 226, and third slide rail 12 are all corresponding to the two second limiting members 221. At the same time, the second positioning mechanism 520 includes only one sliding seat 224. One of the buffer supports 226 is directly fixedly connected to the side frame of the frame 10. The lower end of the second limiting member 221 corresponding to the buffer support 226 is connected to the buffer seat through multiple second buffer members 225. The other buffer support 226 is fixed on the sliding seat 224 and is connected to the bottom frame of the frame 10 through the sliding seat 224 and the second slide rail 223.

[0115] In some examples, the second buffer 225 is a buffer spring that extends in the vertical direction. Multiple second buffers 225 are arranged at intervals along the second direction. This allows the second limiting member 221 to exert a uniform buffering force in the second direction, reducing the risk of stress concentration.

[0116] In some embodiments of the present invention, such as Figure 4 As shown, the second limiting member 221 has two second limiting ribs 2211 on the side facing the battery cell 600. These two ribs extend vertically and are spaced apart in the second direction. They are adapted to engage with the two side surfaces of the battery body 610 in the second direction. The side surface of the second limiting member 221 facing the battery cell 600 restricts the position of the battery body 610 in the first direction, while the two second limiting ribs 2211 restrict the position of the battery cell 600 in the second direction. Thus, the second limiting member 221 can simultaneously limit the battery body 610 in both the first and second directions, effectively preventing the battery cell 600 from shaking, tilting, or tipping over during transport by the transport fixture 100. Furthermore, the two second limiting ribs 2211 also prevent the battery body 610 from tipping over the second limiting member 221 in the second direction, improving the reliability of fixing the battery cell 600.

[0117] In some embodiments of the present invention, such as Figure 1As shown, the conveying fixture 100 also includes a base plate 40, on which a plurality of adjusting slide rails 41 are provided. The plurality of adjusting slide rails 41 extend along a second direction and are spaced apart in a first direction. The frame 10 is slidably supported on the plurality of adjusting slide rails 41. For example, the base plate 40 can be a horizontally arranged rectangular plate shape, and the number of adjusting slide rails 41 can be two, three, four, five or more. The plurality of adjusting slide rails 41 can extend along the width direction of the base plate 40 and be evenly spaced along the length direction of the base plate 40, so that the force on the frame 10 can be evenly distributed on the base plate 40 through the plurality of adjusting slide rails 41.

[0118] In this embodiment, by setting the adjustable slide rail 41, the relative position of the frame 10 and the base plate 40 in the second direction can be adjusted. Thus, during the pressing process, the position of the frame 10 can be adaptively adjusted within a certain range so that the pressing head 541 of the pressing mechanism 540 can be directly aligned with the top cover 620 of the battery cell 600 on the conveying fixture 100, reducing positioning difficulty and accuracy, and improving assembly efficiency and pressing quality.

[0119] The following is for reference. Figures 13-26 A battery processing apparatus 1000 according to an embodiment of the second aspect of the present invention is described.

[0120] like Figure 13 and Figure 14 As shown, the battery processing equipment 1000 according to a second aspect embodiment of the present invention includes: a battery conveying device 200, which includes a conveying line and a conveying fixture 100 for a battery cell 600 according to the first aspect embodiment of the present invention. The conveying fixture 100 is disposed on the conveying line and conveyed via the conveying line. In some examples, the battery conveying device 200 may be a magnetic levitation conveying device, and the conveying fixture 100 is conveyed to each workstation via the conveying line of the battery conveying device 200.

[0121] According to the battery processing equipment 1000 of the present invention, by setting a conveying fixture 100 for the battery cell 600 of the first aspect embodiment described above, the conveying fixture 100 can be compatible with multiple workstations, so that the battery cell 600 can be directly conveyed and processed between multiple workstations through the conveying fixture 100 without the need for handling operations by a robotic arm. As a result, the production cycle of the battery processing equipment 1000 can be avoided, the production efficiency of the battery processing equipment 1000 can be improved, and the overall performance of the battery processing equipment 1000 can be improved.

[0122] In some embodiments of the present invention, such as Figures 13-16 , Figure 20 and Figure 21As shown, the battery processing equipment 1000 may further include a pressing device 500, which includes: a first positioning mechanism 510, a second positioning mechanism 520, a clamping drive mechanism 530, and a pressing mechanism 540. The first positioning mechanism 510 is used to position the conveying fixture 100 in the vertical direction; the second positioning mechanism 520 is used to clamp and fix the battery body 610 located on the conveying fixture 100; the clamping drive mechanism 530 is used to drive the clamping assembly 30 to clamp and release the top cover 620 located on the top of the battery body 610; and the pressing mechanism 540 is used to press the top cover 620 onto the top of the battery body 610.

[0123] In some examples, such as Figure 13 , Figure 16 and Figure 25 As shown, the pressing mechanism 540 includes a pressing head 541 and a pressing drive 542. The pressing drive 542 can be a drive cylinder. The pressing drive 542 is connected to the pressing head 541 and is used to drive the pressing head 541 to move in the up and down direction so as to press the top cover 620 onto the top of the battery body 610.

[0124] After the battery conveying device 200 conveys the conveying fixture 100, along with the battery body 610 and top cover 620 within the conveying fixture 100, to the pressing station via the conveying line, the first positioning mechanism 510 first positions the fixture vertically to lock the reference position; then the second positioning mechanism 520 clamps and fixes the battery body 610 to prevent it from shifting during pressing. It should be noted that before the conveying fixture 100 reaches the pressing station, the first clamping member 311 of the first clamping mechanism 31 of the clamping assembly 30 is in the first clamping position to clamp the top cover 620, creating a vertical gap between the top cover 620 and the battery body 610, while the second clamping member 321 of the second clamping mechanism 32 is in the second release position.

[0125] Next, the clamping drive mechanism 530 drives the first clamping member 311 of the first clamping mechanism 31 of the clamping assembly 30 to release the top cover 620 and correct the alignment posture of the top cover 620 and the battery body 610. Finally, the pressing mechanism 540 moves down and precisely presses the top cover 620 onto the top of the battery body 610. After pressing, the clamping drive mechanism 530 drives the second clamping member 321 of the second clamping mechanism 32 of the clamping assembly 30 to switch to the second clamping position and press the top cover 620 against the top of the battery body 610. Finally, each mechanism is reset in sequence, and the battery conveying device 200 can transfer the conveying fixture 100 and the battery cell 600 to the next process (such as the welding process).

[0126] In the above technical solution, the first positioning mechanism 510 can accurately lock the upper and lower positions of the conveying fixture 100, establish a unified pressing benchmark, effectively compensate for the assembly tolerances of the conveying fixture 100 and the pressing device 500, and avoid pressing misalignment caused by benchmark offset. The second positioning mechanism 520 firmly clamps and fixes the battery body 610, which can prevent the battery body 610 from shifting or tilting during the pressing process, and ensure the alignment accuracy between the top cover 620 and the battery body 610. The clamping drive mechanism 530 drives the clamping assembly 30 to release the top cover 620, which can avoid the clamping assembly 30 interfering with the pressing operation of the pressing mechanism 540. The clamping drive mechanism 530 drives the clamping assembly 30 to clamp the top cover 620, which can reliably hold the pressed top cover 620 in the pressed position, so that the assembly surface of the top cover 620 and the battery body 610 are completely fitted. The pressing mechanism 540 can stably output pressing force to ensure that the top cover 620 is tightly connected to the battery body 610, thereby improving the robustness of the assembly structure.

[0127] The pressing device 500 of this embodiment can automatically position and press the conveying jig 100 and battery cells 600, significantly improving the pressing yield and work efficiency. It can also adapt to the processing requirements of battery cells 600 of different specifications, avoiding damage to the battery cells 600 caused by rigid pressing. In addition, the pressing device 500 of this embodiment can directly press the battery cells 600 on the conveyor line of the battery conveying device 200, avoiding the impact on the production cycle caused by handling the battery cells 600, and improving the production cycle and production efficiency of the battery processing equipment 1000.

[0128] In some embodiments of the present invention, such as Figure 20 , Figure 23 and Figure 24 As shown, the first positioning mechanism 510 may include: a first support 511, a first movable frame 513, a first positioning element 512, a second positioning element 514, and a first positioning drive element 515. The first support 511 is provided with the first positioning element 512; the first movable frame 513 is movably disposed on the first support 511 in the vertical direction; the second positioning element 514 is disposed on the first movable frame 513 and is spaced apart from the first positioning element 512 in the vertical direction; the first positioning drive element 515 is connected to the first movable frame 513 and is used to drive the first movable frame 513 to move vertically. The first positioning mechanism 510 clamps the positioning plate 212 of the conveying fixture 100 in the vertical direction through the first positioning element 512 and the second positioning element 514 to position the conveying fixture 100 in the vertical direction. In some examples, the first positioning drive element 515 is a drive cylinder.

[0129] When the conveying fixture 100 moves the battery body 610 and the top cover 620 to the pressing station, the first positioning mechanism 510 is activated. The first positioning drive 515 drives the first moving frame 513 to move downward along the first support 511, which in turn drives the second positioning member 514 to move downward closer to the first positioning member 512 preset on the first support 511, until the first positioning member 512 and the second positioning member 514 clamp the positioning plate 212 of the conveying fixture 100 in the vertical direction, thereby accurately locking the vertical reference position of the conveying fixture 100.

[0130] In the above technical solution, the first positioning drive 515 drives the first moving frame 513 to move in the vertical direction, which in turn drives the second positioning component 514 to move closer to or away from the first positioning component 512. This enables bidirectional clamping of the positioning plate 212 of the conveying fixture 100, firmly locking the conveying fixture 100 on the preset vertical reference surface. This effectively eliminates the gap error between the conveying fixture 100 and the conveying line of the battery conveying device 200, prevents the conveying fixture 100 from shifting due to vibration or force during the pressing process, and improves the alignment accuracy and consistency of the pressing.

[0131] In some embodiments of the present invention, such as Figure 23 and Figure 24 As shown, the second positioning element 514 is a positioning wheel, which is rotatably mounted on the first moving frame 513 along the horizontal axis. This converts the sliding friction with the positioning plate 212 into rolling friction, significantly reducing resistance during clamping and releasing, preventing wear on the surface of the positioning plate 212, and without affecting the clamping and positioning accuracy in the vertical direction.

[0132] In some embodiments of the present invention, such as Figure 23 and Figure 24 As shown, there are multiple second positioning elements 514, which are spaced apart in a first direction within the horizontal plane. For example, the number of second positioning elements 514 can be two, three, four, five, or more. The multiple second positioning elements 514 can apply a balanced clamping force to the positioning plate 212 of the conveying fixture 100 from multiple support points, effectively preventing the positioning plate 212 from tilting or twisting under force.

[0133] In some examples, such as Figure 23 and Figure 24As shown, the first positioning element 512 is a positioning bolt. Multiple first positioning elements 512 correspond one-to-one with multiple second positioning elements 514, and are vertically aligned; for example, the first positioning element 512 is positioned directly below the corresponding second positioning element 514. The first bracket 511 has threaded holes extending vertically, and the first positioning elements 512 pass through these threads. The vertical relative position of the first positioning elements 512 within the threaded holes is adjustable. Therefore, the position of the first positioning elements 512 can be adjusted to accommodate positioning plates 212 at different heights.

[0134] In some embodiments of the present invention, such as Figures 20-22 As shown, the second positioning mechanism 520 includes a first positioning component 521, which includes a first positioning block 5211 and a first driving member 5212. The first driving member 5212 is connected to the first positioning block 5211 and is used to drive the first positioning block 5211 to move along a first direction. The first positioning block 5211 is adapted to abut against the surface of the battery body 610 in a second direction. The first direction, the second direction, and the up-down direction are perpendicular to each other. In this embodiment, the first driving member 5212 drives the first positioning block 5211 to move along the first direction and abut against the surface of the battery body 610 in the second direction. This can establish a lateral positioning reference in the direction perpendicular to the thickness of the battery body 610, eliminate the horizontal movement gap of the battery body 610 within the conveying fixture 100, and ensure that the battery body 610 is fixed in position during the press-fitting process. At the same time, the travel of the first positioning block 5211 is adjustable, allowing it to adapt to battery bodies 610 of different sizes and specifications, improving versatility and compatibility. In some examples, the first driving member 5212 is a driving cylinder.

[0135] In some embodiments of the present invention, such as Figures 20-22As shown, the second positioning mechanism 520 includes a second positioning component 522, which includes a second positioning block 5221 and a second driving member 5222. The second driving member 5222 is connected to the second positioning block 5221 and is used to drive the second positioning block 5221 to move along a first direction. There are two second positioning blocks 5221, which are arranged opposite to each other in the first direction. The two second positioning blocks 5221 respectively abut against the opposite side surfaces of the battery body 610 in the first direction. In this embodiment, the two second positioning blocks 5221 arranged opposite to each other in the first direction can apply a balanced clamping force to the battery body 610 from both sides, effectively eliminating the assembly gap of the battery body 610 in the first direction and preventing the battery cell 600 from moving horizontally or tilting when pressed. At the same time, it can also improve the center positioning accuracy of the battery body 610 in the conveying fixture 100, providing a stable foundation for the subsequent pressing of the top cover 620, and significantly improving processing efficiency and processing quality. In some examples, the second drive element 5222 is a drive electric cylinder, and the second drive element 5222 corresponds one-to-one with the second positioning block 5221.

[0136] In some embodiments of the present invention, such as Figure 20 and Figure 21 As shown, the first positioning component 521 includes a plurality of first positioning blocks 5211 arranged at intervals along a first direction; for example, the first positioning component 521 includes two, three, four or more first positioning blocks 5211. The first positioning component 521 has a plurality of first positioning blocks 5211, which can realize multi-point uniform support and positioning of the battery body 610, disperse the positioning force, and avoid local deformation of the battery cell 600 due to single-point force.

[0137] In some embodiments of the present invention, such as Figure 20 and Figure 21 As shown, in the first direction, multiple first positioning blocks 5211 are arranged between two second positioning blocks 5221 of the second positioning assembly 522. Thus, the two second positioning blocks 5221 can clamp the battery cell 600 at both ends in the first direction, and the multiple first positioning blocks 5211 can support the battery cell 600 on one side surface in the second direction, jointly achieving the positioning of the battery body 610. This disperses the positioning force, preventing deformation of the battery body 610 due to excessive local force, and also eliminates gaps between the battery cell 600 in the first and second directions in the horizontal plane, ensuring precise alignment of the center position of the battery body 610 with the pressing reference, significantly improving the alignment accuracy of the top cover 620 pressing.

[0138] In some embodiments of the present invention, such as Figure 13 and Figure 21As shown, the second positioning mechanism 520 further includes a mounting plate 523 and a third driving member 524. The first positioning component 521 and the second positioning component 522 are both disposed on the mounting plate 523. The third driving member 524 is connected to the mounting plate 523 and is used to drive the mounting plate 523 to move along the second direction. When the battery conveying device 200 conveys the conveying fixture 100 together with the battery cell 600 to the pressing device 500, the third driving member 524 can drive the mounting plate 523 to move along the second direction, so that the first positioning component 521 and the second positioning component 522 gradually approach the conveying fixture 100. After the first positioning component 521 and the second positioning component 522 approach the conveying fixture 100, the third driving member 524 can stop. At this time, the first positioning component 521 and the second positioning component 522 can respectively position the battery body 610. After the battery cell 600 is pressed, the first positioning component 521 and the second positioning component 522 reset. Finally, the third driving member 524 drives the mounting plate 523 to move away from the conveying line of the battery conveying device 200 along the second direction, so as to avoid the second positioning mechanism 520 interfering with the battery conveying device 200 continuing to convey the conveying fixture 100 and the battery cell 600.

[0139] In some embodiments of the present invention, such as Figure 13 and Figure 14 As shown, there are multiple second positioning mechanisms 520, which are arranged on opposite sides of the battery conveying device 200. These multiple second positioning mechanisms 520 can provide positioning support for the battery cell 600 on both sides in the second direction, making the positioning clamping force of the battery body 610 on both sides in the second direction more balanced, preventing the battery cell 600 from shifting. Furthermore, they can further disperse the positioning force, improve positioning accuracy, and ensure the alignment accuracy of the press-fitting process.

[0140] The positioning process of the second positioning mechanism 520 on the conveying fixture 100 by the above embodiment is described in detail below.

[0141] First, the third driving member 524 drives the mounting plate 523 to move along the second direction, causing the first positioning component 521 and the second positioning component 522 integrated on the mounting plate 523 to synchronously approach the conveying fixture 100 and the battery body 610, until the plurality of first positioning blocks 5211 and the plurality of second positioning blocks 5221 reach the preset horizontal positioning reference area. Then, the second driving member 5222 of the second positioning component 522 actuates, driving the two second positioning blocks 5221 arranged opposite each other in the first direction to move synchronously towards each other, applying a balanced clamping force from both sides of the battery body 610 in the first direction, defining the horizontal position of the battery body 610 in the first direction. Next, the first driving member 5212 of the first positioning member 512 actuates synchronously, driving the plurality of first positioning blocks 5211 arranged between the two second positioning blocks 5221 and spaced apart along the first direction to move, abutting against the two side surfaces of the battery body 610 in the second direction, eliminating the gap error in the second direction. Among them, multiple second positioning mechanisms 520 arranged on opposite sides of the battery conveying device 200 simultaneously complete the above-mentioned clamping and supporting actions, apply symmetrical positioning forces from both sides of the battery body 610 to ensure that the battery body 610 is stable in the horizontal plane and accurately aligned with the pressing reference.

[0142] After the top cover 620 is pressed into place, each mechanism operates in reverse order. Specifically, the first positioning block 5211 retracts first, the second positioning block 5221 simultaneously releases its clamping on the battery body 610, and then the third driving component 524 drives the mounting plate 523 to retreat to the clearance position in the second direction, releasing the battery body 610 and the conveying fixture 100. The conveying fixture 100 then carries the pressed-in battery to the next process.

[0143] In some embodiments of the present invention, such as Figure 6 As shown, the clamping assembly 30 includes a first clamping mechanism 31, which includes a first clamping member 311 and a first pushing member 314. The first pushing member 314 is connected to the first clamping member 311 and is used to drive the first clamping member 311 to move between a first clamping position of clamping the top cover 620 and a first releasing position of releasing the top cover 620.

[0144] Furthermore, such as Figure 13 and Figure 19 As shown, the clamping drive mechanism 530 includes a first unlocking mechanism 531, which includes a first unlocking block 5311 and an unlocking drive member 5312. The unlocking drive member 5312 is connected to the first unlocking block 5311 and is used to drive the first unlocking block 5311 to move along a second direction. The first unlocking block 5311 is used to push the first pusher 314 to move along the second direction, so that the first clamping member 311 moves from a first clamping position to a first release position. In some examples, such as... Figure 19 As shown, the unlocking drive component 5312 is a drive cylinder.

[0145] In some examples, the first unlocking block 5311 has an unlocking end, the frame 10 of the conveying fixture 100 is provided with an unlocking hole on one side in the second direction, the first pusher 314 is disposed in the conveying fixture 100, and the unlocking end of the first pusher 314 is exposed at the unlocking hole position. The first unlocking block 5311 is adapted to extend into the conveying fixture 100 through the unlocking hole to abut against the unlocking end and push the first pusher 314 to move through the unlocking end.

[0146] In some examples, there are multiple first unlocking mechanisms 531, which are arranged at intervals along a first direction. The number of first unlocking mechanisms 531 can be consistent with the number of first clamping mechanisms 31 of multiple conveying fixtures 100 simultaneously accommodated by the pressing device 500, and they correspond one-to-one. Thus, the multiple first clamping mechanisms 31 of the multiple conveying fixtures 100 can be unlocked to release the top cover 620 of the battery cell 600.

[0147] After the conveying fixture 100 and the battery body 610 are positioned in the pressing device 500, the unlocking drive 5312 receives an instruction and drives the first unlocking block 5311 to extend along the second direction. The first unlocking block 5311 gradually approaches the unlocking hole and extends into the frame 10 from the unlocking hole position, contacting the contact end of the first pusher 314. The first unlocking block 5311 pushes the first pusher 314 to move synchronously along the second direction, thereby driving the first clamping member 311 connected to the first pusher 314 to switch from the first clamping position pressing the top cover 620 to the first release position disengaging from the top cover 620. After the top cover 620 is pressed, the unlocking drive 5312 drives the first unlocking block 5311 to retract in the opposite direction, and the first pusher 314 and the first clamping member 311 are reset.

[0148] In the above technical solution, the first unlocking block 5311 is driven by the unlocking drive component 5312 to transmit force, thereby realizing the switching of the first clamping component 311 from the first clamping position to the first release position. This can avoid the error of manual unlocking, improve unlocking efficiency, ensure the continuity of the automated production line, and improve processing efficiency.

[0149] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the clamping assembly 30 includes a second clamping mechanism 32, which includes a second clamping member 321 and a push-pull member 323. The push-pull member 323 is connected to the second clamping member 321 and is used to drive the second clamping member 321 to rotate between a second clamping position that presses against the top cover 620 and a second release position that releases the top cover 620.

[0150] Furthermore, such as Figures 15-18As shown, the clamping drive mechanism 530 includes a clamping mechanism 532, which includes a clamping structure and a clamping drive member 5323. The clamping structure is configured to clamp the push-pull member 323. The clamping drive member 5323 is connected to the clamping structure and drives the push-pull member 323 to move up and down through the clamping structure, so that the second clamping member rotates between a second clamping position and a second release position. In some examples, the clamping drive member 5323 is a drive cylinder.

[0151] In the above technical solution, by clamping the push-pull member 323 through the clamping structure to transmit power, it can be ensured that the driving force of the pressing drive member 5323 is stably transmitted to the second clamping member 321, thereby improving the accuracy of clamping and releasing actions. It can also realize the automatic switching of the second clamping member 321 between the second clamping position and the second releasing position without manual intervention, thereby improving the production line cycle time and the processing efficiency of the battery processing equipment 1000.

[0152] In some embodiments of the present invention, such as Figures 15-17 As shown, the clamping structure includes clamping blocks 5321 and clamping drive members 5322. There are two clamping blocks 5321 arranged opposite each other in a second direction. The clamping drive members 5322 are connected to the clamping blocks 5321 and are used to drive the clamping blocks 5321 to move along the second direction, so that the two clamping blocks 5321 cooperate to clamp the push-pull member 323. In some examples, the clamping drive member 5322 is a slide cylinder.

[0153] In some examples, there are multiple clamping mechanisms 532, which are arranged at intervals along the first direction. The number of clamping mechanisms 532 can correspond one-to-one with the number of second clamping mechanisms 32 of multiple conveying fixtures 100 that can operate simultaneously in the pressing device 500. Alternatively, two adjacent second clamping mechanisms 32 of two adjacent conveying fixtures 100 in the first direction can share one clamping mechanism 532. That is, the clamping block 5321 of one clamping mechanism 532 can simultaneously clamp the push-pull members 323 of two adjacent second clamping mechanisms 32, and simultaneously drive the second clamping members 321 of the two second clamping mechanisms 32 to rotate between a second clamping position and a second release position.

[0154] In this embodiment, the push-pull component 323 is symmetrically clamped by two clamping blocks 5321 in the second direction, which can apply a balanced clamping force to the push-pull component 323, ensuring that the force on the push-pull component 323 is not offset and avoiding slippage or displacement deviation during power transmission. By driving the clamping blocks 5321 through the clamping drive component 5322, the clamping and releasing actions of the push-pull component 323 can be realized automatically without manual intervention, thereby improving the automated production cycle of the battery processing equipment 1000 and increasing production efficiency.

[0155] The working process of the clamping drive mechanism 530 of the above embodiment driving the second clamping mechanism 32 to lock the top cover 620 is described in detail below.

[0156] After the top cover 620 is pressed onto the top of the battery body 610 by the pressing head 541 of the pressing mechanism 540, the clamping drive 5322 of the clamping structure receives a command and drives two clamping blocks 5321 arranged opposite each other in the second direction to move synchronously towards each other in the second direction. At this time, the clamping blocks 5321 are aligned with the corresponding side of the clamping handle 3234 on the push-pull member 323, gradually approaching and aligning the clamping part of the clamping block 5321 with the clamping grooves 3235 on both sides of the clamping handle 3234, so that the clamping part of the clamping block 5321 is embedded in the clamping groove 3235, forming a close-fitting concave-convex fit structure, realizing circumferential limiting and rigid clamping of the push-pull member 323, and locking the push-pull member 323.

[0157] After confirming that the clamping block 5321 stably clamps the clamping handle 3234 through the clamping groove 3235, the clamping drive 5323 is activated. The clamping drive 5323 drives the push-pull member 323 to move upward through the clamping structure. The push-pull member 323, through the cooperation of the pushing part 3231 and the driven part 3212, converts the linear motion into the rotational motion of the second clamping member 321, so that the second clamping member 321 rotates around the preset rotating axis to the second clamping position that fits the surface of the top cover 620, forming a uniform clamping force on the top cover 620, ensuring that the mounting surface of the top cover 620 and the battery body 610 are completely fitted together, thus achieving the clamping of the top cover 620.

[0158] Finally, the clamping drive 5322 of the clamping structure drives the two clamping blocks 5321 to move in opposite directions along the second direction. The clamping parts of the clamping blocks 5321 completely disengage from the clamping grooves 3235 on both sides of the clamping handle 3234, releasing the lock on the push-pull member 323. The clamping blocks 5321 also return to the initial clearance position, and the clamping mechanism 532 completes the clamping drive of the second clamping member 321.

[0159] In some embodiments of the present invention, such as Figure 13 , Figure 14 and Figure 26As shown, the pressing device 500 also includes a dust removal mechanism 550, which has a suction port 551 positioned close to and facing the top cover 620 of the battery cell 600. In some examples, there may be multiple dust removal mechanisms 550, which are arranged opposite each other in a second direction. The suction port 551 may be formed as an elongated opening extending along a first direction. In this embodiment, the dust removal mechanism 550 can remove dust and impurities throughout the pressing process, preventing impurities from entering the sealing surface between the top cover 620 and the battery body 610, effectively improving the sealing performance of the top cover 620 and the pressing reliability, and enhancing the safety performance of the battery cell 600. Furthermore, the linkage design between the dust removal mechanism 550 and the pressing process eliminates the need for additional manual cleaning steps, ensuring the continuity of automated production line operations and further improving overall production efficiency and product yield.

[0160] According to a third aspect embodiment of the present invention, the battery processing method is applied to the battery processing apparatus 1000 according to the second aspect embodiment of the present invention, such as... Figure 27 As shown, the battery processing method includes: placing a battery cell 600 into the clamping space 101 of the conveying fixture 100, and clamping and fixing the battery body 610 of the battery cell 600 by the limiting component 20; confirming that the top cover 620 is located on top of the battery body 610 and that the top cover 620 is not pressed onto the battery body 610; clamping and fixing the top cover 620 by the first clamping member 311, and confirming that the second clamping member 321 is located in the second release position; the battery conveying device 200 conveys the conveying fixture 100 to the pressing device 500; and the first positioning mechanism 510 positions the battery body 610. The first clamping mechanism 531 uses a first unlocking block 5311 to push the first clamping member 311 from the first clamping position to the first release position; the pressing mechanism 540 presses the top cover 620 onto the top of the battery body 610; the clamping drive mechanism 530 uses a clamping structure to clamp the push-pull member 323 of the second clamping mechanism 32; the clamping drive mechanism 530 uses the push-pull member 323 to drive the second clamping member 321 to rotate from the second release position to the second clamping position.

[0161] In other words, during the production process of the battery processing equipment 1000, the battery body 610 is first positioned within the clamping space 101 of the conveying fixture 100. The battery body 610 is fixed to the conveying fixture 100 by the limiting component 20. The top cover 620 is placed on top of the battery body 610 and clamped by the first clamping member 311, so that there is a certain gap between the top cover 620 and the battery body 610 in the vertical direction. Then, the conveying fixture 100 is conveyed to the pressing device 500 by the battery conveying device 200 (such as a magnetic levitation conveying device). During the conveying process, multiple conveying fixtures 100 can be grouped into a fixture group according to the number of battery cells 600 that the pressing device 500 can press at one time. For example, four conveying fixtures 100 can be grouped into a fixture group. Each time, multiple conveying fixtures 100 of a fixture group, along with the battery cells 600, are conveyed to the pressing device 500.

[0162] Then, multiple first positioning mechanisms 510 clamp and fix the positioning plates 212 of multiple conveying fixtures 100 to achieve positioning of the conveying fixtures 100 in the vertical direction. Then, the second positioning mechanism 520 positions the battery body 610 in the first and second directions. Next, the first clamping member 311 releases the top cover 620 through the first unlocking mechanism 531. After confirming that the battery body 610, the top cover 620 and the pressing head 541 of the pressing mechanism 540 are accurately aligned, the pressing head 541 is used to press the top cover 620 into the battery body 610. Then, the clamping drive mechanism 530 drives the second clamping member 321 to press the top cover 620 through the clamping block 5321 to achieve clamping and fixing of the top cover 620, ensuring that the top cover 620 can be kept in the pressing position.

[0163] Finally, the mechanisms of the pressing device 500 are reset, and the battery conveying device 200 conveys the conveying fixture 100 to the welding device of the welding process. Before welding, during welding, or after welding, the welding device can drive the second clamping member 321 to release the top cover 620 through the relevant drive structure (a structure similar to the clamping drive mechanism 530 in the pressing device 500).

[0164] According to the battery processing method of the present invention, the conveying fixture 100 can be compatible with the pressing station of the battery cell 600 and the processing stations before and after the pressing station. Moreover, the pressing process can be carried out directly on the conveying line of the battery conveying device 200. No robotic arm is required to handle the process, which can avoid affecting the production cycle and improve production efficiency.
