The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0048] Reference below Figure 1-Figure 10 The invention describes a spacer ring buckle device and a battery processing device according to an embodiment of the present application.

[0049] Among them, the spacer is used to be set on the outer ring of the pole ear to protect the pole ear, and the spacer buckling device is used to buckle the spacer to the outer side of the pole ear.

[0050] like Figure 1 and Figure 2 As shown, the spacer ring fastening equipment of the embodiment of the present application includes: a battery cell conveying line 1, a spacer ring conveying line 3 and a spacer ring fastening assembly 5, a plurality of battery cell clamps 2 for carrying battery cells 7 are arranged on the battery cell conveying line 1, and a plurality of spacer ring clamps 4 for carrying spacers are arranged on the spacer ring conveying line 3.

[0051] The cell clamp 2 is used for clamping the cell 7 for transportation, and the spacer clamp 4 is used for clamping the spacer for transportation.

[0052] like Figure 3 and Figure 6 As shown, the battery cell conveyor line 1 includes a first driving section 11 and a first guide rail section 12 that are connected. The first driving section 11 can be used to drive the battery cell clamp 2 to move along the battery cell conveyor line 1. The first driving section 11 can use magnetic levitation technology or a mechanical structure such as a chain or belt drive to drive the battery cell clamp 2 to move along the path of the first driving section 11; the battery cell clamp 2 can move along the first guide rail section 12, and the first guide rail section 12 provides a guiding effect on the battery cell clamp 2.

[0053] like Figure 3 and Figure 7As shown, the spacer conveyor line 3 includes a connected second drive section 31 and a second guide rail section 32. The second drive section 31 can be used to drive the spacer clamp 4 to move along the spacer conveyor line 3. The second drive section 31 can use magnetic levitation technology or a mechanical structure such as a chain or belt drive to drive the spacer clamp 4 to move; the spacer clamp 4 can move along the second guide rail section 32, and the second guide rail section 32 provides a guiding effect on the spacer clamp 4.

[0054] like Figure 3 and Figure 4 As shown, the spacer assembly 5 includes a spacer mechanism 51 that moves along a fastening track, and the spacer mechanism 51 is used to fasten the spacer to the battery cell 7.

[0055] The snap-fit ​​track, the working part of the first guide rail segment 12 and the working part of the second guide rail segment 32 are arranged in parallel and side by side, so that the target battery cell clamp 2 moved to the first guide rail segment 12, the target spacer clamp 4 moved to the second guide rail segment 32 and the target snap-fit ​​spacer mechanism 51 located on the snap-fit ​​track can be aligned.

[0056] The spacer mechanism 51 is used to drive the battery cell clamp 2 to move to the end of the first driving section 11 and the spacer clamp 4 to move to the end of the second driving section 31, respectively, to move synchronously along the first guide rail section 12 and the second guide rail section 32, and to buckle the spacer to the battery cell 7 during the synchronous movement process.

[0057] For example, when the battery cell clamp 2 moved to the end of the first driving section 11 and the spacer clamp 4 moved to the end of the second driving section 31 are aligned, and the spacer buckle mechanism 51 moves to a position on the fastening track that is aligned with the end of the first driving section 11 and the end of the second driving section 31, the battery cell clamp 2, the spacer clamp 4 and the spacer buckle mechanism 51 are aligned, and the battery cell clamp 2, the spacer clamp 4 and the spacer buckle mechanism 51 can be coupled and connected by means of meshing, clamping or magnetic attraction, and the spacer buckle mechanism 51 continues along the fastening track. Movement, and at the same time, the spacer mechanism 51 drives the coupled battery cell clamp 2 and the spacer clamp 4 to move along the first guide rail section 12 and the second guide rail section 32 respectively, that is, the spacer mechanism 51, the battery cell clamp 2 coupled with the spacer mechanism 51, and the spacer clamp 4 coupled with the spacer mechanism 51 move synchronously. During the synchronous movement of the three, the spacer mechanism 51 fastens the spacer on the spacer clamp 4 to the battery cell 7 on the battery cell clamp 2, thereby completing the fastening of the spacer and the battery cell 7.

[0058] In the above process, the spacer buckling mechanism 51, the battery cell clamp 2 coupled to the spacer buckling mechanism 51, and the spacer clamp 4 coupled to the spacer buckling mechanism 51 can move synchronously, and the spacer buckling action of the spacer and the battery cell 7 can be completed in the process of synchronous movement of the three. There is no need to set a beat pause such as a pause of the spacer clamp 4 or a pause of the battery cell clamp 2 to perform the buckling separately, thereby greatly improving the production efficiency.

[0059] According to the spacer buckling equipment provided by the present application, by setting the battery cell conveying line 1, the spacer conveying line 3 and the spacer buckling assembly 5, the buckling track, the working part of the first guide rail section 12 of the battery cell conveying line 1 and the working part of the second guide rail section 32 of the spacer conveying line 3 are arranged in parallel and side by side, and the spacer buckling mechanism 51 can drive the battery cell clamp 2 that moves to the end of the first driving section 11 and the spacer clamp 4 that moves to the end of the second driving section 31 to move synchronously along the first guide rail section 12 and the second guide rail section 32 respectively, and buckle the spacer to the battery cell 7 during the synchronous movement process, without setting a beat pause such as a pause of the spacer clamp 4 or a pause of the battery cell clamp 2 to perform the buckling separately, thereby greatly improving the production efficiency.

[0060] In some embodiments, Figure 2 and Figure 3 As shown, the fastening track and the working part of the second guide rail segment 32 can be arranged on both sides of the working part of the first guide rail segment 12 with the working part of the first guide rail segment 12 as the symmetry axis. When the spacer is fastened on the battery cell 7 with a single-sided output ear, the spacer conveying line 3 and the spacer assembly 5 on one side of the first guide rail segment 12 work, and when the spacer is fastened on the battery cell 7 with a double-sided output ear, the spacer conveying line 3 and the spacer assembly 5 on both sides of the first guide rail segment 12 work.

[0061] The fastening track may be a straight line or an arc, which may be set according to the layout space and the length of the production line.

[0062] In some embodiments, Figure 2 and Figure 3 As shown, both sides of the cell conveying line 1 are provided with spacer conveying lines 3 , and the buckle spacer ring assemblies 5 are arranged on both sides of the second guide rail section 32 .

[0063] In this embodiment, the spacer conveying line 3 and the spacer buckle assembly 5 can be symmetrically distributed with the battery cell conveying line 1 as the symmetry axis, so that the spacer buckle operation can be performed on the battery cells 7 with double-sided pole ears and the battery cells 7 with single-sided pole ears, thereby improving the application scenarios.

[0064] In this embodiment, the battery cell clamp 2 is coupled with the spacer clamp 4 moving to the end of the second driving section 31 when it moves to the end of the first driving section 11, and the spacer clamps 4 on both sides are coupled with the buckling spacer mechanisms 51 on both sides, that is, the battery cell clamp 2, the spacer clamp 4, and the buckling spacer clamp 4 can be coupled on the buckling trajectory, and the battery cell clamp 2, the spacer clamp 4 and the buckling spacer clamp 4 are driven to rotate synchronously by the high-speed rotation of the turntable 52, and the buckling of the spacer is completed during the rotation process, thereby improving the synchronization of the three on the buckling trajectory and improving work efficiency.

[0065] In some embodiments, Figure 4As shown, the spacer assembly 5 includes: a turntable 52 and a spacer mechanism 51. The turntable 52 is used to rotate around a first axis. The spacer mechanism 51 is installed on the turntable 52. The spacer mechanism 51 can rotate and reciprocate as the turntable 52 rotates, thereby realizing multiple spacer mechanisms 51 working simultaneously and improving production efficiency.

[0066] Among them, the working part of the first guide rail segment 12 and the working part of the second guide rail segment 32 are both arc-shaped with the center of curvature located on the first axis, that is, the working part of the first guide rail segment 12 and the working part of the second guide rail segment 32 are both concentrically arranged with the rotation trajectory of the turntable 52, so that the battery cell clamp 2 located in the working part of the first guide rail segment 12 and the spacer clamp 4 located in the working part of the second guide rail segment 32 are parallel to the movement trajectory of the spacer buckle mechanism 51 located on the turntable 52, and the battery cell clamp 2 located in the working part of the first guide rail segment 12 and the spacer clamp 4 located in the working part of the second guide rail segment 32 and the spacer buckle mechanism 51 located on the turntable 52 all move around the first axis, thereby improving the synchronization and position accuracy of the battery cell clamp 2 located in the working part of the first guide rail segment 12 and the spacer clamp 4 located in the working part of the second guide rail segment 32 and the spacer buckle mechanism 51 located on the turntable 52, thereby increasing the accuracy of the buckling.

[0067] In this embodiment, the battery cell clamp 2 moves along the first driving section 11 to the end of the first driving section 11, and the end of the first driving section 11 is connected to the working part of the first arc-shaped guide rail section 12; the spacer ring clamp 4 moves along the second driving section 31 to the end of the second driving section 31, and the end of the second driving section 31 is connected to the working part of the second arc-shaped guide rail section 32. During the rotation of the turntable 52, the spacer ring buckling mechanism 51 is brought to the position on the buckling trajectory corresponding to the end of the first driving section 11. The target spacer ring buckling mechanism 51 drives the battery cell clamp 2 that moves to the end of the first driving section 11 and the spacer ring clamp 4 that moves to the end of the second driving section 31 to move synchronously along their respective arc-shaped guide sections, and the spacer ring is buckled to the battery cell 7 during the synchronous movement process; after the spacer ring buckling action is completed, the spacer ring buckling mechanism 51 is separated from the battery cell clamp 2 and the spacer ring clamp 4, the battery cell clamp 2 continues to move along the battery cell conveying line 1, and the spacer ring clamp 4 continues to move along the spacer ring conveying line 3, and the spacer ring buckling mechanism 51 is driven by the turntable 52 to move again to the position on the buckling trajectory corresponding to the end of the first driving section 11, and the spacer ring buckling mechanism 51 repeats the above process.

[0068] In some embodiments, Figure 4 As shown, there are multiple spacer buckling mechanisms 51 , which are installed on the turntable 52 at intervals along the circumferential direction, and each spacer buckling mechanism 51 is responsible for the synchronous buckling of a battery cell fixture 2 and a spacer fixture 4 .

[0069] In this embodiment, during the rotation of the turntable 52, the turntable 52 can drive multiple spacer buckling mechanisms 51 and the battery cell clamps 2 and spacer clamps 4 coupled with the corresponding spacer buckling mechanisms 51 to move synchronously along the arc path, and multiple battery cell clamps 2 and spacer clamps 4 complete the spacer buckling action during the movement. After the spacer buckling is completed, the turntable 52 continues to rotate, and the battery cell clamps 2 and spacer clamps 4 that have been buckled are moved out of the buckling track, and the next battery cell clamp 2 and spacer clamp 4 are brought into the buckling position with the next spacer buckling mechanism 51, and the above process is repeated.

[0070] Through this design, the design of multiple buckling ring mechanisms 51 allows each buckling ring mechanism 51 to work independently without interfering with each other during the process of the turntable 52 rotating one circle, thereby completing the multi-point synchronous buckling of multiple battery cells 7 and the spacers, which significantly improves the production efficiency; and the design of multiple buckling ring mechanisms 51 also makes the buckling ring equipment have higher redundancy and reliability. Even if one of the buckling ring mechanisms 51 fails, the other buckling ring mechanisms 51 can still continue to work, thereby improving the continuity and stability of the production line.

[0071] In some embodiments, Figure 3 As shown, when spacer conveyor lines 3 are provided on both sides of the battery cell conveyor line 1 and the spacer assembly 5 is arranged on both sides of the second guide rail section 32, the turntable 52 includes two turntables 52, which are arranged on both sides of the second guide rail section 32 and are coaxially arranged.

[0072] In some embodiments, Figure 3 and Figure 6 As shown, the first driving section 11 includes a first introduction section 111 located upstream of the first guide rail section 12 , and the cell fixture 2 carrying the cell 7 is suitable for moving in the first introduction section 111 , and the cell fixture 2 is suitable for loading materials at the first introduction section 111 .

[0073] The first introduction section 111 and the first guide rail section 12 may be smoothly connected to increase the smooth transition of the battery cell fixture 2 from the first driving section 11 to the first guide rail section 12 .

[0074] Exemplarily, an arc segment may be provided at the end of the first introduction section 111, and the center of curvature of the arc segment and the center of curvature of the first guide rail section 12 may be arranged on both sides of the battery cell conveying line 1, so that the first introduction section 111 and the first guide rail section 12 can be smoothly connected.

[0075] like Figure 3 and Figure 7 As shown, the second driving section 31 includes a second introduction section 311 located upstream of the second guide rail section 32 , and the spacer clamp 4 carrying the spacer is suitable for moving in the second introduction section 311 , and the spacer clamp 4 is suitable for loading materials at the second introduction section 311 .

[0076] The second introduction section 311 and the second guide rail section 32 can be smoothly connected to increase the smooth transition of the spacer clamp 4 from the second driving section 31 to the second guide rail section 32 .

[0077] Exemplarily, an arc segment may be provided at the end of the second introduction section 311, and the center of curvature of the arc segment and the center of curvature of the second guide rail section 32 may be arranged on both sides of the spacer conveying line 3, so that the second introduction section 311 and the second guide rail section 32 can be smoothly connected.

[0078] Among them, Figure 1 and Figure 2 As shown, parts of the first introduction section 111 and the second introduction section 311 may be straight line sections extending along the X direction.

[0079] In this embodiment, the first introduction section 111 and the second introduction section 311 are arranged in parallel and spaced apart, that is, the spacer clamp 4 and the battery cell clamp 2 are spaced apart in the direction along the first axis, thereby reducing the interference between the spacer clamp 4 and the battery cell clamp 2 in the direction of the first axis, increasing the accuracy of the alignment of the spacer clamp 4 and the battery cell clamp 2, reducing the difficulty of coupling with the spacer buckling mechanism 51, and reserving installation space for the buckling track.

[0080] In some embodiments, the center of curvature of the first guide rail segment 12 can be higher than the first lead-in segment 111, and the center of curvature of the second guide rail segment 32 can be higher than the second lead-in segment 311, so that the speed of the battery cell clamp 2 at the end of the first lead-in segment 111 is reduced to 0, and the speed of the spacer clamp 4 at the end of the second lead-in segment 311 is reduced to 0, thereby improving the accuracy of the alignment and engagement of the battery cell clamp 2 at the end of the first lead-in segment 111 and the spacer clamp 4 at the end of the second lead-in segment 311, so as to reduce the impact and vibration of the battery cell clamp 2 during the loading process.

[0081] In some embodiments, the first drive section 11 includes a first lead-out section 112 located downstream of the first guide rail section 12, and the cell fixture 2 carrying the battery cell 7 with the spacer ring fastened thereon is suitable for moving in the first lead-out section 112; the second drive section 31 includes a second lead-out section 312 located downstream of the second guide rail section 32, and the spacer ring fixture 4 not carrying the spacer ring is suitable for moving in the second lead-in section 311.

[0082] like Figure 3 and Figure 6As shown, the battery cell conveying line 1 includes a first driving section 11, a first guide rail section 12 and a first lead-out section 112 which are arranged in sequence along the conveying direction. The first driving section 11, the first guide rail section 12 and the first lead-out section 112 can be smoothly connected. The battery cell fixture 2 carrying the battery cell 7 without the spacer ring moves in the first driving section 11, and the battery cell fixture 2 carrying the battery cell 7 with the spacer ring is suitable for moving in the first lead-out section 112, and the battery cell 7 and the spacer ring are engaged in the first guide rail section 12.

[0083] like Figure 3 and Figure 7 As shown, the spacer conveying line 3 includes a second driving section 31, a second guide rail section 32 and a second lead-out section 312 which are arranged in sequence along the conveying direction. The second driving section 31, the second guide rail section 32 and the second lead-out section 312 can be smoothly connected. The spacer clamp 4 carrying the spacer is suitable for moving in the second driving section 31, and the spacer clamp 4 not carrying the spacer is suitable for moving in the second lead-in section 311, and the battery cell 7 and the spacer are buckled in the second guide rail section 32.

[0084] In some embodiments, the end of the first lead-out section 112 is connected to the starting point of the first lead-in section 111, that is, the first drive section 11 and the first guide rail section 12 are connected end to end in sequence (not shown in the figure). After the battery cell clamp 2 transports the battery cell 7 with the spacer ring fastened to the next process, the battery cell clamp 2 without carrying the battery cell 7 can move along the battery cell conveyor line 1 to the first lead-in section 111 and repeat the spacer ring fastening process. The battery cell clamp 2 can be reused to increase production efficiency.

[0085] like Figure 7 As shown, the end of the second lead-out section 312 is connected to the starting point of the second lead-in section 311, that is, the second drive section 31 and the second guide rail section 32 are connected end to end in sequence, and the ring clamp 4 that does not carry the ring after completing the ring buckling process can enter the second lead-in section 311 along the end of the second lead-out section 312, and repeat the ring buckling process. The ring clamp 4 can be reused to increase production efficiency.

[0086] In some embodiments, the first driving section 11 and the second driving section 31 both include a magnetic drive structure, and the battery cell clamp 2 and the spacer clamp 4 are both provided with magnetic parts. The magnetic drive structure of the first driving section 11 is used to drive the battery cell clamp 2 through the magnetic parts of the battery cell clamp 2, and the magnetic drive structure of the second driving section 31 is used to drive the spacer clamp 4 through the magnetic parts of the spacer clamp 4.

[0087] The magnetic drive structure includes multiple magnetic drive structures, which are arranged in sequence along the first drive section 11. The multiple magnetic drive structures are connected into a passage. The multiple magnetic drive structures are responsible for driving the battery cell clamp 2 on the first drive section 11 and transporting the starting point of the first drive section 11 of the battery cell clamp 2 to the end of the first drive section 11.

The multiple magnetic drive structures are responsible for driving the spacer clamp 4 on the second drive section 31 and transporting the spacer clamp 4 from the starting point of the second drive section 31 to the end of the second drive section 31.

[0089] In this embodiment, through the coordinated use of the magnetic drive structure and the battery cell clamp 2 and the spacer clamp 4, the battery cell clamp 2 and the spacer clamp 4 can be automatically transported and processed, reducing the risk of damage to the battery cell clamp 2 and the spacer clamp 4, thereby improving production efficiency.

[0090] In some embodiments, the first driving section 11 and the second driving section 31 may both include a slide rail and a slider that slides with the slide rail. The magnetic drive structure of the first driving section 11 and the magnetic drive structure of the second driving section 31 are respectively slidably installed on their respective corresponding slide rails through their respective corresponding sliders. The first driving section 11 and the second driving section 31 are also provided with a driving mechanism, which is used to drive the movement of the magnetic drive structure on the slide rail.

[0091] The slide rail is an important component of the first drive section 11 and the second drive section 31, providing a moving track for the magnetic drive structure. The slide rail can be designed to be a straight line or an arc extending along the X direction, or a combination of the two. The material of the slide rail has good wear resistance and corrosion resistance to improve stability and precision under long-term use. The slider slides with the slide rail to support the magnetic drive structure to slide on the slide rail. The slider is usually equipped with a rolling bearing or a sliding bearing to reduce friction and wear and improve sliding efficiency. The slide rail is also equipped with a driving mechanism to drive the magnetic drive structure and the corresponding slider to slide.

[0092] The drive mechanism is the power source for the movement of the magnetic drive structure. It enables the magnetic drive structure to move smoothly along the slide rail by providing the necessary torque and speed. Common drive mechanisms include motors, cylinders, and hydraulic cylinders.

[0093] In the above description, the design of the slide rail and the slider enables the magnetic drive structure to move freely on the first drive section 11 and the second drive section 31, and the rapid movement and precise positioning of the magnetic drive structure help to improve the overall efficiency of the buckle spacer device.

[0094] In some embodiments, Figure 6 As shown, the battery cell fixture 2 has multiple battery cell 7 loading stations, and the battery cell fixture 2 can load and transport multiple battery cells 7 at the same time; the spacer clamp 4 has multiple groups of spacer loading stations 41, and the spacer clamp 4 can carry multiple spacers at the same time, and the multiple groups of spacer loading stations 41 match the multiple battery cell 7 loading stations of the battery cell fixture 2; the spacer buckling mechanism 51 has multiple spacer buckling parts 511, and the multiple spacer buckling parts 511 can buckle the combination of multiple battery cells 7 and spacers at the same time.

[0095] In the embodiment, the multi-station, multi-component design of the battery cell clamp 2, the spacer clamp 4 and the spacer buckling mechanism 51 can complete the spacer buckling of multiple battery cells 7 in a single synchronous process, thereby improving production efficiency and meeting the needs of large-scale production.

[0096] Among them, the one-to-one correspondence between the number of battery cell 7 loading stations of the battery cell clamp 2, the number of spacer loading stations 41 of the spacer clamp 4, and the number of spacer fastening parts 511 of the spacer fastening mechanism 51 improves the accuracy of fastening and significantly improves the overall production efficiency.

[0097] In some embodiments, Figure 7 and Figure 8 As shown, the spacer clamp 4 includes: a base 42 and a slot 43, the slot 43 is slidably installed on the base 42 along the distribution direction of the first guide rail section 12 and the second guide rail section 32, and the slot 43 is provided with a spacer loading station 41; the spacer buckling mechanism 51 includes: a base 512, a pushing member 513 and a spacer buckling member 511, the pushing member 513 is used to push the slot 43 to the buckling station, and the spacer buckling member 511 is used to push the spacer to buckle.

[0098] It should be noted that, since the tabs of the battery cell 7 protrude from the battery cell 7 body, if the slots 43 and the tabs of the battery cell 7 are simultaneously located at the fastening station, the tabs of the battery cell 7 will interfere with the slots 43 and the tabs will be easily damaged.

[0099] In this embodiment, the slot 43 is arranged to be able to slide on the base 42 along the distribution direction of the first guide rail section 12 and the second guide rail section 32. After the spacer clamp 4 is aligned with the battery cell clamp 2, the pole ear is already at the snap-fitting position. At this time, the pushing member 513 can push the slot 43 to the snap-fitting position, and the spacer snap-fitting member 511 pushes the spacer to snap together, which not only solves the interference between the pole ear of the battery cell 7 and the slot 43, but also completes the snap-fitting of the spacer.

[0100] The card slot 43 and the base 42 may be connected by translational cooperation of a slide rail and a slider, or may be connected by sliding cooperation of an elastic member.

[0101] In some embodiments, Figure 8 As shown, the card slot 43 includes: a first sub-card slot 431 and a second sub-card slot 432, which are respectively used to load the sub-spacer ring 6.

[0102] The spacer is divided into two sub-spacers 6, which can form a closed spacer when connected. The two sub-spacers 6 are located in the first sub-slot 431 and the second sub-slot 432 respectively.

[0103] The spacer fastener 511 includes: Figure 5As shown, the first sub-fastening member 5111 and the second sub-fastening member 5112 are aligned with the sub-spacers 6 of the first sub-slot 431 and the second sub-slot 432 respectively when the slot 43 is located at the fastening position.

[0104] The first sub-fastening component 5111 can be used to drive the sub-spacer ring 6 in the first sub-slot 431 to move toward the second sub-slot 432, and the second sub-fastening component 5112 can be used to drive the sub-spacer ring 6 in the second sub-slot 432 to move toward the first sub-slot 431, that is, the sub-spacer ring 6 in the first sub-slot 431 and the sub-spacer ring 6 in the second sub-slot 432 move toward each other under the drive of the first sub-fastening component 5111 and the second sub-fastening component 5112 until the two sub-spacer rings 6 are connected to form a complete spacer ring.

[0105] Among them, the first sub-slot 431 and the second sub-slot 432 can be relatively arranged along the distribution direction perpendicular to the first guide rail segment 12 and the second guide rail segment 32, that is, the two sub-spacers 6 are relatively arranged along the distribution direction perpendicular to the first guide rail segment 12 and the second guide rail segment 32. After the pushing member 513 pushes the first sub-slot 431 and the second sub-slot 432 to the snap-fitting station along the distribution direction of the first guide rail segment 12 and the second guide rail segment 32, the first sub-slot 431 and the second sub-slot 432 are respectively aligned with the sub-spacers 6 of the first sub-slot 431 and the second sub-slot 432, and the pole ear is located in the space formed by the first sub-slot 431 and the second sub-slot 432. The sub-spacers 6 in the first sub-slot 431 and the second sub-slot 432 move towards a direction of approaching each other under the drive of the first sub-slot 5111 and the second sub-slot 5112 until the two sub-spacers 6 are connected to form a complete spacer, thereby completing the snap-fitting of the spacer with the battery cell 7.

[0106] The first sub-slot 431 and the second sub-slot 432 can both be C-shaped parts, and the first sub-slot 431 and the second sub-slot 432 are arranged relative to form a ring. When the buckle station is engaged, the ring formed by the first sub-slot 431 and the second sub-slot 432 is sleeved on the outer side of the battery cell 7 tab.

[0107] In some embodiments, the card slot 43 can set multiple spacer loading stations 41 along the extension direction of the spacer conveyor line 3, and the multiple spacer loading stations 41 are arranged in alignment with the multiple battery cell 7 loading stations, so that multiple battery cells 7 can be fastened with spacers at one time, thereby improving production efficiency.

[0108] In some embodiments, Fig. 9 As shown, the base 42 is provided with an avoidance groove at the fastening position. When the pushing member 513 moves the card slot 43 to the fastening position, the spacer groove of the card slot 43 is aligned with the avoidance groove, and the spacer fastening member 511 is used to pass through the avoidance groove to push the spacer to fasten.

[0109] In some embodiments, Figure 1 and Figure 8 As shown, the first sub-slot 431 and the second sub-slot 432 are distributed along a direction (Z direction) perpendicular to the battery cell 7 , the first sub-slot 431 is located above the second sub-slot 432 , and the second sub-slot 432 is arranged close to the base 42 .

[0110] When the pushing member 513 moves the card slot 43 to the snap-fitting position, the spacer grooves of the first sub-card slot 431 and the second sub-card slot 432 are aligned with the avoidance groove, the second sub-slot 5112 passes through the avoidance groove to push the sub-spacer 6 in the second sub-card slot 432 to move upward and connect with the sub-spacer 6 in the first sub-card slot 431, and the first sub-slot 5111 passes through the avoidance groove to push the sub-spacer 6 in the first sub-card slot 431 to move downward and connect with the sub-spacer 6 in the second sub-card slot 432.

[0111] The spacer ring fastening device of the present application is described in detail below using a specific embodiment.

[0112] Take the technical solution of this patent as an example: 8 groups of spacer buckle mechanisms 51 (16 stations in total) are evenly distributed on the turntable 52, the turntable 52 rotates at 75° / s; the coupling area wrap angle is 180°, the coupling time = 180°÷75° = 2.4s; the spacer buckle action time = spacer advance 0.3s + spacer buckle 0.3s + return to origin 0.6s = 1.2s < coupling time; therefore, this solution can realize the spacer buckle in the coupling motion area. Beat = 360°÷16÷75° = 0.3s.

[0113] In the related art, the spacer is fastened when the battery cell 7 is stationary, and multiple groups of actions such as positioning the battery cell 7, pushing the spacer, and fastening the spacer are coordinated to complete. After the spacer is fastened, the battery cell 7 can be moved to the next station only after all the mechanisms return to the origin. It takes at least 1.5 seconds to complete the above actions (positioning the battery cell 7 and pushing the spacer 0.3 seconds + fastening the spacer 0.3 seconds + each mechanism returns to the origin 0.6 seconds + changing the position of the battery cell 7 0.3 seconds). It can be seen that this application does not need to pause to perform the fastening alone, thereby greatly improving production efficiency.

[0114] like Figure 1As shown, the spacer buckling equipment includes: a spacer buckling assembly 5, a spacer conveying line 3 and a battery cell conveying line 1. When the spacer clamp 4 moves to the end of the second driving section 31 and the battery cell clamp 2 moves to the end of the first driving section 11, the spacer buckling mechanism 51 is coupled with the battery cell clamp 2 moving to the end of the first driving section 11 and the spacer clamp 4 moving to the end of the second driving section 31. The spacer buckling mechanism 51 drives the battery cell clamp 2 moving to the end of the first driving section 11 and the spacer clamp 4 moving to the end of the second driving section 31 to move synchronously along the first guide rail section 12 and the second guide rail section 32 respectively, and buckles the spacer to the battery cell 7 during the synchronous movement process.

[0115] At the same time, if Figure 1 and Figure 2 As shown, in order to ensure that the spacer ring buckling mechanism 51, the spacer ring clamp 4 and the battery cell clamp 2 do not interfere with each other during the coupling process, the spacer ring buckling mechanism 51, the spacer ring clamp 4 and the battery cell clamp 2 are pulled apart in the direction of the first axis (Y direction) to avoid each other. In this way, multi-station spacer buckling can be achieved during the high-speed rotation of the turntable 52, thereby greatly improving the production efficiency.

[0116] like Figure 6 As shown, a cell conveyor line 1 is provided with cell clamps 2, and each group of cell clamps 2 has two cells 7 (double stations). The cell conveyor line 1 includes a first driving section 11 and a first guide rail section 12 that are connected. The first driving section 11 conveys the cell clamps 2 to the connection between the first driving section 11 and the first guide rail section 12 through a magnetic drive structure. The cell clamps 2 are coupled with the spacer clamps 4 at the end of the first driving section 11, and then the spacer clamps 4 drive the cell clamps 2 to perform synchronous movement.

[0117] The cell clamp 2 and the spacer clamp 4 with the spacer ring fastened are rotated to the unloading position with the turntable 52, the cell clamp 2, the spacer ring clamp 4 and the spacer ring fastening mechanism 51 are separated, and the cell clamp 2 is driven by the magnetic drive structure of the first lead-out section 112 and transported to the next station.

[0118] like Figure 7 and Figure 8 As shown, a plurality of spacer clamps 4 are arranged on the spacer conveyor line 3, and the spacer clamps 4 include: a base 42, a slot 43 and a spring, and the slot 43 includes a first sub-slot 431 and a second sub-slot 432.

[0119] After the spacer is loaded into the spacer clamp 4, the upper and lower sub-spacers 6 are respectively pressed and fixed by the spring plungers in the first sub-slot 431 and the second sub-slot 432, so as to reduce the possibility of the sub-spacers 6 falling or shifting during the rotation of the spacer clamp 4. The spacer clamp 4 is transported to the connection between the second driving section 31 and the second guide rail section 32 through the magnetic drive structure, and the spacer clamp 4 is coupled with the spacer buckle mechanism 51 at the end of the second driving section 31, and then the rotating disk 52 mechanism is used to rotate the coupled spacer buckle mechanism 51, the spacer clamp 4 and the battery clamp 2 at high speed to perform synchronous rotation.

[0120] like Figure 1 As shown, when the spacer clamp 4 that has completed the spacer buckling rotates with the turntable 52 to the unloading position, the spacer clamp 4 is separated from the spacer buckling mechanism 51, and the spacer clamp 4 is driven by the magnetic drive structure of the second outlet section 312. After the upper and lower spacers are loaded at the spacer loading station, it returns to the starting point of the second import section 311 to continue the previous coupling process.

[0121] like Fig.10 As shown, spring plungers are installed in the spacer grooves of the first sub-slot 431 and the second sub-slot 432 in the spacer clamp 4, and four spring plungers are installed at the marked positions in each spacer groove. When the sub-spacer 6 is inserted into the groove, the spring plunger is compressed, and the spring plunger presses the four surfaces of the sub-spacer 6, thereby ensuring that the sub-spacer 6 is fixed during the rotation of the spacer clamp 4. When the spacer is buckled, the spring plunger automatically retracts by pressing down the sub-spacer 6, and the spring plunger automatically pops out after the spacer moves out of the range of the spring plunger.

[0122] like Figure 4 As shown, the spacer buckle assembly 5 includes a rotating disk 52 and a spacer buckle mechanism 51, wherein the spacer buckle mechanism 51 includes: a base 512, a pusher 513 and a spacer buckle member 511. In the working part of the first rail segment 12 and the working part of the second rail segment 32, when the battery cell fixture 2, the spacer fixture 4 and the spacer buckle mechanism 51 on the rotating disk 52 complete the coupling and synchronous rotation, the pusher 513 in the spacer buckle mechanism 51 extends out, and the first sub-slot 431 and the second sub-slot 432 in the spacer fixture 4 are simultaneously pushed from the initial position to the spacer buckle position. The movement of the first sub-fastening member 5111 in the Y direction is controlled by the same power source as the pushing member 513, and the second sub-fastening member 5112 is fixed in the Y direction at the position of the waiting spacer to be fastened. After the first sub-slot 431 and the second sub-slot 432 are pushed into place, the first sub-fastening member 5111 and the second sub-fastening member 5112 are also in the position of the waiting spacer to be fastened. At this time, the first sub-fastening member 5111 and the second sub-fastening member 5112 synchronously press the sub-spacer 6 to the spacer fastening position. After the upper and lower sub-spacers 6 are fastened, the first sub-fastening member 5111 and the second sub-fastening member 5112 are first retreated, and then the pushing member 513 is retreated to the initial position. The first sub-slot 431 and the second sub-slot 432 in the spacer clamp 4 are pushed back to the initial position by the spring. At this point, the spacer fastening of the battery cell 7 is completed.

[0123] After the spacer is fastened, the turntable 52, the spacer fixture 4 and the battery cell fixture 2 are separated, wherein the spacer fixture 4 is transported to the spacer loading position by the second lead-out section 312 to complete the spacer loading; the battery cell fixture 2 is transported to the next station by the first lead-out section 112.

[0124] The battery cell 7 spacer buckling equipment of the related art needs to be operated when the battery cell 7 is in a stationary state, and the spacer buckling equipment is complicated, resulting in a long process time and low production efficiency. At the same time, it is difficult to speed up the equipment and the speed-up space is limited.

[0125] The spacer ring fastening equipment provided in the present application combines a turntable 52 with a battery cell conveyor line 1 and a spacer ring conveyor line 3. After the battery cell clamp 2, the spacer ring clamp 4 and the spacer ring fastening mechanism 51 are coupled, the turntable 52 rotates to drive the three to rotate synchronously, thereby completing the spacer ring fastening action during the movement of the battery cell 7. By appropriately increasing the rotation speed of the turntable 52 and the number of spacer ring fastening mechanism 51 workstations evenly distributed on the turntable 52, the equipment beat can be effectively improved, thereby realizing a high-speed rotating spacer ring fastening process.

[0126] Compared with the battery cell 7 spacer buckling equipment of the related art, the present application can greatly improve the production efficiency of the equipment and solve the bottleneck problem of the spacer buckling equipment speed-up. In addition, the present solution splits the existing complex spacer buckling equipment: the spacer positioning part is independent and uses a magnetic suspension conveyor line to drive the circulation; the spacer buckling part is evenly distributed on the turntable 52 and rotates with the turntable 52, which can effectively simplify the spacer buckling equipment.

[0127] An embodiment of the present application also provides a battery processing device, including the spacer ring fastening device of any of the above embodiments.
