Description

[0002] The battery cell is the most important component of a battery. It undergoes a series of processes, including mechanical / ultrasonic leveling, encapsulation, casing, current collector welding, and sealing, before being assembled into a finished battery. Therefore, the performance of the battery cell directly impacts the overall battery performance, making the cell preparation and current collector welding processes crucial before assembly.

[0003] Currently, when welding current collectors at the ends of battery cells, the cells are typically fed along a linearly distributed cell feeding line. A current collector loading line is set up on one side of the cell feeding line, which transfers the current collectors to a welding clamping mechanism on the cell feeding line. The welding clamping mechanism clamps the current collectors between the end of the battery cell and the welding head, so that the current collectors can be welded using laser welding equipment.

[0055] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0056] The following is combined Figures 1-6 The present invention provides a detailed description of a manifold welding system through specific embodiments and application scenarios.

[0057] like Figure 1 and Figure 2 As shown, the present invention provides a collector plate welding system, including: a conveyor line 1, a collector plate feeding mechanism 2, a welding turntable 3, and welding equipment 4.

[0058] The conveyor line 1, the collecting plate feeding mechanism 2 and the welding equipment 4 are arranged around the welding turntable 3. The welding turntable 3 includes a turntable assembly 31 and a welding clamping assembly 32, which is arranged circumferentially along the turntable assembly 31.

[0059] The conveyor line 1 is used to transport the battery cells to be welded to the turntable assembly 31. The turntable assembly 31 is used to drive the battery cells to be welded to move circumferentially and to transport the semi-finished batteries that have been welded to the conveyor line 1.

[0060] The current collector loading mechanism 2 is used to transfer the current collector to the welding clamping assembly 32, and the welding clamping assembly 32 is used to fix the current collector to the end of the battery cell to be welded.

[0061] Welding equipment 4 is used to weld the current collector to the end of the cell to be welded, so as to obtain a semi-finished battery.

[0062] It is understood that the conveyor line 1 in this embodiment can be extended along a straight track or a curved track, and there is no specific limitation on this. While meeting the conveying requirements of the above-mentioned cells to be welded and semi-finished batteries, it is necessary to minimize the occupation of site space.

[0063] Optionally, the conveyor line 1 in this embodiment includes a first conveyor section 11, a second conveyor section 12, and a third conveyor section 13; the first conveyor section 11, the second conveyor section 12, and the third conveyor section 13 are connected in sequence; the upper side of the first conveyor section 11 is provided with a feeding guide frame 101; the second conveyor section 12 and the welding turntable 3 are arranged opposite to each other; the upper side of the third conveyor section 13 is provided with a discharging guide frame 102; the feeding guide frame 101 can guide the battery cells to be welded conveyed by the first conveyor section 11 to move onto the welding turntable 3; the semi-finished batteries on the welding turntable 3 can reach the third conveyor section 13 under the guidance of the discharging guide frame 102.

[0064] The feeding guide frame 101 includes a first guide rod and a second guide rod, which are arranged side by side. Both the first guide rod and the second guide rod extend along the extension direction of the first conveying section 11. Multiple battery cells to be welded can be arranged between the first guide rod and the second guide rod, and the multiple battery cells to be welded are arranged sequentially along the extension direction of the first conveying section 11.

[0065] Accordingly, the unloading guide frame 102 includes a third guide rod and a fourth guide rod, which are arranged side by side and extend along the extension direction of the third conveying section 13. Multiple semi-finished batteries can be arranged between the third guide rod and the fourth guide rod, and the multiple semi-finished batteries are arranged sequentially along the extension direction of the third conveying section 13.

[0066] Optionally, the conveyor line 1 in this embodiment can be configured as a chain plate conveyor. The chain plate conveyor is provided with multiple battery cell carriers 5. The multiple battery cell carriers 5 are arranged sequentially along the conveying direction of the chain plate conveyor. Each battery cell carrier 5 is used to store the battery cell to be welded. The battery cell carrier 5 is open at the top, and the upper end of the battery cell to be welded is exposed at the open end of the battery cell carrier 5.

[0067] In some examples, in order to facilitate welding the current collector to the end of the cell to be welded, at least part of the welding clamping assembly 32 can be installed on the upper side of the turntable assembly 31 and can rotate together with the turntable assembly 31 under the drive of the turntable assembly 31.

[0068] Thus, while the turntable assembly 31 drives the battery cell to be welded to move circumferentially along the turntable assembly 31, it can also ensure that the welding clamping assembly 32 fixes the current collector to the end of the battery cell to be welded. Therefore, when the battery cell to be welded and the current collector arrive at the welding station together, the current collector can be welded to the end of the battery cell to be welded by the welding equipment 4.

[0069] The turntable assembly 31 can be understood as a driving component that drives multiple battery cells to be welded to rotate circumferentially. Optionally, the turntable assembly 31 can be a planar turntable or an annular conveyor chain that extends into a disc shape.

[0070] Meanwhile, the welding clamping assembly 32 can be understood as a fixing component capable of fixing the current collector to the end of the battery cell to be welded. The welding clamping assembly 32 includes at least a first clamping part and a second clamping part, which are used to clamp and fix the current collector. To facilitate welding of the current collector, one of the first clamping part and the second clamping part can be configured as a welding pressure head to press the current collector onto the end of the battery cell to be welded.

[0071] In some examples, this embodiment may provide multiple sets of welding equipment 4 along the circumference of the turntable assembly 31. Each set of welding equipment 4 includes a mounting frame 41 and a galvanometer laser welding machine 42. The galvanometer laser welding machine 42 is distributed on the upper side of the welding clamping assembly 32. Thus, based on the galvanometer laser welding machine 42, this embodiment can weld the current collector to the end of the battery cell to be welded by laser penetration welding.

[0072] As can be seen from the above, in this embodiment, by arranging the conveyor line 1, the collector plate feeding mechanism 2, and the welding equipment 4 around the welding turntable 3, the battery cell to be welded can be conveyed to the turntable assembly 31 of the welding turntable 3 via the conveyor line 1, and the collector plate can be conveyed to the welding clamping assembly 32 of the welding turntable 3 via the collector plate feeding mechanism 2. Then, the turntable assembly 31 drives the battery cell to be welded and the welding clamping assembly 32 carrying the collector plate to move to the welding station corresponding to the welding equipment 4, and the welding equipment 4 welds the collector plate to the end of the battery cell to be welded. This arrangement structure not only reduces the space occupied by the collector plate welding system, but also allows multiple sets of welding equipment 4 to be arranged along the circumference of the turntable assembly 31 of the welding turntable 3, thereby improving the welding efficiency of the collector plate.

[0073] In some embodiments, such as Figure 3As shown, the welding clamping assembly 32 in this embodiment includes a cam disk 321 and a plurality of clamping assemblies 322.

[0074] A cam disk 321 is located on the upper side of the turntable assembly 31, and multiple clamping components 322 are arranged circumferentially on the cam disk 321. A cam structure 3212 is provided on the cam disk 321, and each clamping component 322 is connected to the cam structure 3212 and can switch between a first state and a second state under the drive of the cam structure 3212.

[0075] In the first state, the clamping port of the clamping component 322 is open to receive the current collector from the current collector feeding mechanism 2; in the second state, the clamping port of the clamping component 322 is closed to fix the current collector to the upper end of the battery cell to be welded.

[0076] Thus, based on the linkage between the cam structure 3212 and each clamping component 322, when the battery cell to be welded has not reached the welding station, the cam structure 3212 can drive the clamping port of the clamping component 322 to be in an open state. This setting facilitates the transfer of the collector plate to the clamping port of the clamping component 322 by the collector plate feeding mechanism 2, preventing interference between the feeding path of the collector plate feeding mechanism 2 and the clamping component 322.

[0077] Correspondingly, when the battery cell to be welded and the current collector plate arrive at the welding station, the cam structure 3212 can drive the clamping port of the clamping assembly 322 to be in a closed state. This setting facilitates the clamping assembly 322 to fix the current collector plate to the upper end of the battery cell to be welded, so that the current collector plate can be welded to the end of the battery cell to be welded by the welding equipment 4.

[0078] Based on the above settings, in this embodiment, multiple battery cells to be welded driven by the turntable assembly 31 and multiple clamping assemblies 322 can be arranged one-to-one relative to each other. Based on the cam structure 3212, the states of multiple clamping assemblies 322 can be linked and controlled simultaneously. At each welding station corresponding to the welding turntable 3, it can be ensured that the upper end of each battery cell to be welded is equipped with a current collector to be welded, so that welding operations of multiple current collectors can be performed simultaneously, which helps to improve the welding efficiency of current collectors.

[0079] In some embodiments, such as Figure 5 As shown, the clamping assembly 322 in this embodiment includes a fixing member 3221, a supporting member 3222, and a linkage member 3223.

[0080] The fixing member 3221 is disposed on the cam disk 321, the support member 3222 is movably disposed on the side of the fixing member 3221 away from the center of the turntable assembly 31 in the vertical direction, and the linkage member 3223 is movably disposed on the fixing member 3221 in the radial direction of the turntable assembly 31; the support member 3222 is provided with a positioning hole 32221, which is adapted to the upper end of the battery cell to be welded; the first end of the linkage member 3223 is linkedly connected to the cam structure 3212 so that the linkage member 3223 moves relative to the fixing member 3221 under the drive of the cam structure 3212, and the second end of the linkage member 3223 is provided with a welding pressure head 32232.

[0081] When the clamping assembly 322 is in the first state, its clamping port is open. Specifically, the welding pressure head 32232 and the positioning hole 32221 are misaligned. The distance between the welding pressure head 32232 and the center of the turntable assembly 31 is less than the distance between the positioning hole 32221 and the center of the turntable assembly 31. The support member 3222 positions the collecting plate from the collecting plate feeding mechanism 2 through the positioning hole 32221 to prepare for subsequent collecting plate welding operations.

[0082] As the welding turntable 3 rotates, driven by the cam structure 3212, the linkage 3223 extends toward the side away from the center of the turntable assembly 31 until the welding pressure head 32232 on the linkage 3223 moves to the upper side of the positioning hole 32221, so that the clamping assembly 322 switches from the first state to the second state.

[0083] Specifically, when the clamping assembly 322 is in the second state, the welding head 32232 is located above the positioning hole 32221, and the upper end of the battery cell to be welded passes through the positioning hole 32221 to clamp the current collector between the welding head 32232 and the upper end of the battery cell to be welded, thereby fixing the current collector to the upper end of the battery cell to be welded so that the welding operation of the current collector can be performed by the welding equipment 4.

[0084] It should be noted that the linkage 3223 and the fixing member 3221 in this embodiment can be slidably engaged by the first slide rail and the first slide groove, and the first slide rail is arranged to extend radially along the turntable assembly 31.

[0085] Accordingly, the support member 3222 and the fixing member 3221 in this embodiment can be slidably engaged by the second slide rail and the second slide groove, with the second slide rail extending along the vertical direction (the height direction of the welding turntable 3).

[0086] In some embodiments, such as Figure 4 and Figure 5As shown, in order to facilitate the reciprocating movement of the linkage 3223 relative to the fixed member 3221 along the radial direction of the turntable assembly 31 by the cam structure 3212, the cam disk 321 of this embodiment is provided with an annular groove 3211. The annular groove 3211 extends along a cam-shaped trajectory so that the cam structure 3212 is formed on the cam disk 321. The first end of the linkage 3223 is provided with a roller 32231. The roller 32231 is disposed in the annular groove 3211, and the roller 32231 and the cam structure 3212 are in rolling contact along the edge.

[0087] Specifically, the annular groove 3211 in this embodiment includes a first groove segment and a second groove segment. The first groove segment extends along an arc trajectory relative to the center of the turntable assembly 31. The extension path of the second groove segment is not specifically limited; however, the radial distance of the first groove segment relative to the center of the turntable assembly 31 is greater than the radial distance of the second groove segment relative to the center of the turntable assembly 31. In this embodiment, multiple welding devices 4 can be sequentially arranged along the extension direction of the first groove segment.

[0088] Thus, when the roller 32231 moves along the extension direction of the second groove section, the clamping assembly 322 is in the first state to load the collector plate; while when the roller 32231 moves along the extension direction of the first groove section, the clamping assembly 322 is in the second state to perform the welding operation of the collector plate.

[0089] In some embodiments, such as Figure 4 and Figure 5 As shown, the welding clamping assembly 32 in this embodiment includes a lifting plate 323 and an elastic element 3224.

[0090] A lifting plate 323 extends circumferentially along the turntable assembly 31 and is used to support the battery cell to be welded. During the movement of the battery cell to be welded along the turntable assembly 31, the lifting plate 323 changes the height of the upper end of the battery cell relative to the surface of the cam disk 321. An elastic element 3224 is disposed between the support element 3222 and the fixing element 3221 to control the height of the support element 3222 relative to the fixing element 3221.

[0091] Specifically, in this embodiment, the lifting plate 323 is crescent-shaped and includes a first segment, a second segment, and a third segment connected in sequence. The end of the first segment opposite to the second segment extends to the first conveying section 11 of the conveyor line 1, and the thickness of the first segment gradually increases along the extension direction from the first segment to the second segment. The end of the third segment opposite to the second segment extends to the third conveying section 13 of the conveyor line 1, and the thickness of the third segment gradually decreases along the extension direction from the second segment to the third segment. The first groove segment of the annular groove 3211 and the second segment of the lifting plate 323 are arranged vertically opposite each other.

[0092] Thus, when the battery cell carrier 5 carries the battery cell to be welded from the first conveying section 11 of the conveying line 1 to the first section of the lifting plate 323, the clamping assembly 322 is in the first state during the circumferential movement of the battery cell to be welded along the turntable assembly 31. Under the guidance of the first section of the lifting plate 323, the height of the upper end of the battery cell to be welded relative to the surface of the cam disk 321 gradually increases.

[0093] When the cell carrier 5, carrying the cell to be welded, moves to the second section of the lifting plate 323, the clamping assembly 322 is in the second state. The upper end of the cell to be welded rises into the positioning hole 32221 on the support 3222 and extends out of the positioning hole 32221 until the current collector is supported by the upper end of the cell to be welded. Driven by the cam structure 3212, the welding pressure head 32232 on the linkage 3223 moves to the upper side of the positioning hole 32221. Under the combined action of the cam plate and the lifting plate on the clamping assembly, the current collector can be clamped between the welding pressure head 32232 and the upper end of the cell to be welded, so that the welding operation of the current collector can be carried out by the welding equipment 4 to obtain a semi-finished battery.

[0094] When the cell carrier 5 carries the cell to be welded to the third section of the lifting plate 323, the clamping assembly 322 is in the first state, and the upper end of the cell to be welded descends until the upper end of the cell to be welded disengages from the positioning hole 32221 on the support 3222, so that the cell carrier 5 carries the semi-finished battery from the third section of the lifting plate 323 to the third conveying section 13 of the conveying line 1.

[0095] It should be noted that the elastic element 3224 in this embodiment can be a spring. When the battery cell carrier 5 moves along the first or third segment of the lifting plate 323, the spring is in its initial or stretched state, at which point the spring reaches its first length. When the battery cell carrier 5 moves along the second segment of the lifting plate 323, the spring is in its stretched state, at which point the spring reaches its second length. The second length is greater than the first length.

[0096] In some embodiments, such as Figure 3 As shown, in order to facilitate the movement of the battery cell carrier 5 along the extension direction of the lifting plate 323, the turntable assembly 31 of this embodiment includes a support platform 311, a gear drive disk 312, and a barrier 313; the gear drive disk 312 is rotatably mounted on the support platform 311, the barrier 313 is mounted on the support platform 311, the barrier 313 is located outside the gear drive disk 312, and extends circumferentially along the gear drive disk 312.

[0097] Meanwhile, the gear drive disk 312 of this embodiment has multiple toothed grooves along its circumferential edge. Under the limitation of the enclosure 313, the gear drive disk 312 drives the battery cell to be welded to move along the circumferential direction of the gear drive disk 312 through the toothed grooves. After the welding operation of the current collector is completed at the end of the battery cell to be welded, the gear drive disk 312 drives the semi-finished battery obtained by welding to move onto the conveyor line 1 through the toothed grooves.

[0098] Based on the solutions described in the above embodiments, such as Figure 1 and Figure 6 As shown, in order to improve the feeding efficiency of the collection plate and reduce the space occupied by the collection plate feeding mechanism 2, the collection plate feeding mechanism 2 in this embodiment includes a collection plate feeding component 21 and a collection plate feeding turntable 22.

[0099] Specifically, in this embodiment, multiple feeder assemblies 21 are provided, and the multiple feeder assemblies 21 are arranged circumferentially along the feeder turntable 22, which is located on one side of the welding turntable 3.

[0100] Among them, the collector plate feeding assembly 21 is used to transfer the collector plate to the collector plate loading turntable 22, and the collector plate loading turntable 22 then transfers the collector plate to the welding clamping assembly 32.

[0101] Optionally, multiple feeder assemblies 21 can be arranged circumferentially along the circumference of the feeder turntable 22. For example, two feeder assemblies 21 can be provided, and the two feeder assemblies 21 are arranged at a 90° central angle relative to the center of the feeder turntable 22.

[0102] In some embodiments, such as Figure 6 As shown, the feeder assembly 21 of this embodiment includes a feeder storage rack 211, a first transfer assembly 212, and a second transfer assembly 213. Along the radial direction of the feeder turntable 22, the feeder storage rack 211, the first transfer assembly 212, and the second transfer assembly 213 are arranged sequentially, with the second transfer assembly 213 positioned between the first transfer assembly 212 and the feeder turntable 22.

[0103] In practical applications, the first transfer component 212 is used to transfer the collection trays stored on the collection tray storage rack 211 to the second transfer component 213, and the second transfer component 213 is used to transfer the collection trays to the collection tray loading turntable 22.

[0104] In some examples, the collector tray storage rack 211 of this embodiment may be provided with multiple limiting rods, all of which are arranged in a limiting manner, and a receiving space is formed between the multiple limiting rods. Multiple collector trays can be stacked in the receiving space, and the multiple limiting rods are arranged sequentially along the circumference of the collector trays.

[0105] In some examples, the first transfer assembly 212 of this embodiment includes a rotary drive 2121, a first lifting drive 2122, and a first mounting bracket 2123; the output end of the rotary drive 2121 is connected to the first lifting drive 2122, the output end of the first lifting drive 2122 is connected to the middle part of the first mounting bracket 2123, the first end of the first mounting bracket 2123 is provided with a first negative pressure adsorption assembly 201, and the second end of the first mounting bracket 2123 is provided with a second negative pressure adsorption assembly 202.

[0106] In some examples, the second transfer component 213 of this embodiment includes a first linear drive module 2131, a second lifting drive component 2132, and a collector tray 2133; the second lifting drive component 2132 is disposed on the slide of the first linear drive module 2131, and the output end of the second lifting drive component 2132 is connected to the collector tray 2133.

[0107] Thus, in practical applications, the first transfer component 212 can control the first negative pressure adsorption component 201 to be positioned above the collection tray storage rack 211 via the rotation drive component 2121 and the first lifting drive component 2122. During this process, the first linear drive module 2131 drives the second lifting drive component 2132 to move, so that the collection tray bracket 2133 reaches the lower side of the second negative pressure adsorption component 202. After the first negative pressure adsorption component 201 completes the material removal operation on the collection trays stacked on the collection tray storage rack 211, the first transfer component 212... The rotary drive component 2121 of component 2 drives the first mounting bracket 2123 to change direction by 180°. The first negative pressure adsorption component 201 can directly place the adsorbed collection plate on the collection plate bracket 2133 of the second transfer component 213. At this time, the second lifting drive component 2132 can be moved by the first linear drive module 2131 of the second transfer component 213. The collection plate bracket 2133 carries the collection plate to the position of the edge of the collection plate loading turntable 22 so that the collection plate loading turntable 22 can perform the collection plate picking operation again.

[0108] It should be noted that, in order to facilitate the first transfer component 212 in retrieving the collection trays from the collection tray storage rack 211, the collection tray storage rack 211 in this embodiment may be configured with a lifting component 214. The lifting component 214 includes a second linear drive module 2141 and a lifting frame 2142. The slide of the second linear drive module 2141 is connected to the lifting frame 2142, and at least a portion of the lifting frame 2142 can extend into the collection tray storage rack 211 and support the bottom of the stacked collection trays. Thus, as the second linear drive module 2141 drives the lifting frame 2142 to move upward, the stacked collection trays can be gradually raised by the lifting frame 2142 to facilitate the first transfer component 212 in retrieving the collection trays.

[0109] In some embodiments, in order to facilitate the material handling operation of the collecting plate supported on the collecting plate bracket 2133 by the collecting plate feeding turntable 22, the collecting plate feeding turntable 22 of this embodiment includes a rotating plate 221 and a plurality of second mounting brackets 222; the plurality of second mounting brackets 222 are arranged sequentially along the circumference of the rotating plate 221, and each second mounting bracket 222 is provided with a third negative pressure adsorption component 203.

[0110] Thus, driven by the rotating disk 221, the second mounting bracket 222 on the collecting disk feeding turntable 22 can be moved to a position corresponding to the collecting disk feeding assembly 21, so that the collecting disk can be picked up from the collecting disk feeding assembly 21 by the third negative pressure adsorption assembly 203. As the rotating disk 221 continues to rotate, the collecting disk adsorbed by the third negative pressure adsorption assembly 203 can be further transferred to the welding clamping assembly 32.

[0111] It should be noted that, in order to achieve flexible control over the material intake of the collecting plate, the first negative pressure adsorption component 201, the second negative pressure adsorption component 202, and the third negative pressure adsorption component 203 in the above embodiments are respectively connected to the corresponding negative pressure devices. To improve the material intake efficiency of the collecting plate, the first negative pressure adsorption component 201, the second negative pressure adsorption component 202, and the third negative pressure adsorption component 203 can all be equipped with multiple negative pressure suction heads, arranged side-by-side.

[0112] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
