Referring to fig. 1 and fig. 2, the present invention provides an apparatus 10 for assembling a battery cell and an upper cover, where the apparatus 10 for assembling a battery cell and an upper cover includes a welding device 100 and a first carrying device 200.

The welding device 100 includes a driving mechanism 110 and at least two welding carriers 120, and each welding carrier 120 is capable of carrying the core assembly 20. The driving mechanism 110 may adopt a transmission chain, a structure of a motor screw pair cooperating with a slider, a structure of a rotating disk, and the like. Under the driving of the driving mechanism 110, at least two welding carriers 120 can alternately enter the welding station 101, and the core assembly 20 carried by the welding carriers 120 can complete welding at the welding station 101.

The driving mechanism 110 can drive each welding carrier 120 to move between the welding station 101 and the loading and unloading station 102. Specifically, in the present embodiment, the driving mechanism 110 may be provided with at least two driving ends independent of each other, so as to drive each welding carrier 120 to move independently. Thus, the mutual interference generated in the working process of the welding carriers 120 can be avoided. Obviously, in other embodiments, at least two welding carriers 120 may also be driven by the driving mechanism 110 to move synchronously.

In this embodiment, the two feeding and discharging stations 102 are disposed on two opposite sides of the welding station 101, the number of the welding carriers 120 is two, and the two welding carriers 120 can move between the two feeding and discharging stations 102 and the welding station 101 under the driving of the driving mechanism 110.

Thus, the two welding carriers 120 can be independent from each other and do not interfere with each other during the working process. As shown in fig. 2, when the left welding carrier 120 moves to the welding station 101, the right welding carrier 120 moves to the right loading/unloading station 102, so that the assembly 20 can be loaded and unloaded to the right welding carrier 120 when the assembly 20 in the left welding carrier 120 is welded. After the core assembly 20 in the left welding carrier 120 is welded, the left feeding and discharging station 102 can be moved to discharge the welded core assembly 20 and feed the core assembly 20 to be welded into the left welding carrier 120; and the right welding carrier 120 enters the welding station 101, so that the core assembly 20 in the right welding carrier 120 is welded.

The first carrying device 200 includes a feeding mechanism 210 and a discharging mechanism 220, when the welding carrier 120 moves to the loading/unloading station 102, the feeding mechanism 210 can place the core assembly 20 to be welded on the welding carrier 120, and the discharging mechanism 220 can take out the welded core assembly 20 from the welding carrier 120.

The structure of the feeding mechanism 210 and the blanking mechanism 220 is the same, and the suction cup, the clamping jaw and other forms can be adopted, so long as the core assembly 20 can be grabbed. In this embodiment, the first conveying device 200 further includes a first transmission mechanism 230. The first transmission mechanism 230 may be in the form of a transmission chain, and the feeding mechanism 210 and the discharging mechanism 220 are disposed at two independent driving ends of the first transmission mechanism 230. The first transmission mechanism 230 can drive the feeding mechanism 210 and the discharging mechanism 220 to move in the left-right direction shown in fig. 2, so that the feeding mechanism 210 and the discharging mechanism 220 can transfer the grabbed core assembly 120 to a desired position.

It should be noted that, in other embodiments, the feeding mechanism 210 and the discharging mechanism 220 may also be respectively integrated with a multi-axis robot or other mechanisms capable of achieving position transfer, so that the feeding mechanism 210 and the discharging mechanism 220 may also achieve independent movement. In this case, the first transmission mechanism 230 may be omitted.

When one of the welding carriers 120 enters the welding station 101 and performs welding on the core assembly 20, the other welding carriers 120 can be driven by the driving mechanism 110 to move to the loading and unloading station 102. At this time, the blanking mechanism 220 may take out the welded core assembly 20 from the welding carrier 120, and the feeding mechanism 210 may place the core assembly 20 to be welded on the welding carrier 120. In this cycle, at least two welding carriers 120 enter the welding station 101 alternately, so as to realize continuous welding of the core-combining assembly 20. Moreover, in the welding process of one core assembly 20, other core assemblies 20 can be subjected to blanking and feeding, so that the welding time can be reasonably utilized, and the production efficiency can be improved.

In the present embodiment, the apparatus 10 for assembling a battery cell and an upper cover further includes a blanking device 800, the blanking device 800 includes a blanking carrier 810 and a conveying mechanism 820, the blanking mechanism 220 can transfer the welded assembly component 20 from the welding carrier 120 to the blanking carrier 810, and the conveying mechanism 820 can convey the blanking carrier 810 to a designated position.

The conveying mechanism 820 may be a conveying belt, a transmission chain, etc., and under the driving of the conveying mechanism 820, the blanking carrier 810 may move to a position capable of bearing the joint core assembly 20, and after the welded joint core assembly 20 is placed on the blanking carrier 810 by the blanking mechanism 220, the conveying mechanism 820 may drive the blanking carrier 810 and the joint core assembly 20 therein to move to the outside of the apparatus or to a next process. After the core assembly 20 in the blanking carrier 810 is removed, the core assembly 20 is driven by the conveying mechanism 820 to return to the position capable of bearing the core assembly 20 again, and the process is sequentially circulated.

In the present embodiment, each welding carrier 120 can carry a plurality of core assemblies 20, a plurality of welding mechanisms 130 are respectively disposed at two opposite sides of the welding station 101, and the plurality of welding mechanisms 130 at each side can simultaneously weld the plurality of core assemblies 20 in the welding carrier 120. A plurality of welding mechanism 130 weld a plurality of core components 20 simultaneously, can further promote production efficiency.

As shown in fig. 5 and fig. 6, the core assembly 20 includes two battery cells 21 and an upper cover 22, and four welding points are formed between each battery cell 21 and the upper cover 22.

Taking fig. 2 as an example, each welding carrier 120 can bear two core assembly assemblies 20, three welding mechanisms 130 are respectively disposed on two sides of the welding station 101, and the welding mechanisms 130 and the two core assembly assemblies 20 on the welding carrier 120 are respectively numbered in the right-to-right direction. When the welding carrier 120 is located at the opposite side of the No. 1 and No. 2 welding mechanisms 130, the No. 1 welding mechanism 130 and the No. 2 welding mechanism 130 respectively weld the right welding point of the No. 1 combining core component 20 and the left welding point of the No. 2 combining core component 20; after welding, the welding carrier 120 moves a predetermined distance and moves to the opposite sides of the No. 2 welding mechanism 130 and the No. 3 welding mechanism 130. At this time, the welding mechanism 130 of No. 2 and the welding mechanism 130 of No. 3 can respectively weld the left welding point of the assembly 20 of No. 1 and the right welding point of the assembly 20 of No. 2, thereby completing the welding of the assembly 20 of two assemblies on the welding carrier 120.

It should be noted that in other embodiments, the number of welding mechanisms 130 may also be set to correspond to the number of core-engaging assemblies 20 in the welding carrier 120. Moreover, each welding mechanism 130 is capable of welding two welding points on the left and right simultaneously.

In order to improve the automation degree of the apparatus 10 for assembling a battery cell and a cover, please refer to fig. 1 again, in this embodiment, the apparatus 10 for assembling a battery cell and a cover further includes a cover feeding device 300, a battery cell feeding device 400, a second carrying device 500, and a core combining transfer device 600.

The upper cover feeding device 300 and the battery cell feeding device 400 can respectively provide the upper cover 22 and the battery cell 21, the second carrying device 500 includes an upper cover grabbing component 510 and a battery cell grabbing component 520, the core transfer device 600 is closed and includes a core closing carrier 610, the upper cover grabbing component 510 and the battery cell grabbing component 520 can respectively grab the upper cover 22 and the battery cell 21 provided by the upper cover feeding device 300 and the battery cell feeding device 400 and place the upper cover 22 and the battery cell 21 in the core closing carrier 610, so as to obtain the core closing assembly 20 through assembly. Specifically, a cell 21 may be placed on the core combining carrier 610, and then the cover 22 is placed thereon, and finally a cell 21 is placed thereon, so as to obtain a core combining assembly 20.

Further, the core combining relay device 600 can drive the core combining carrier 610 to move to a position where the carried core combining component 20 can be grabbed by the feeding mechanism 210. The core combining carrier 610 may be moved to a position capable of receiving the electrical core 21 and the upper cover 22, and after the electrical core 21 and the upper cover 22 captured by the cover capturing component 510 and the electrical core capturing component 520 are successfully received and the preparation of the core combining assembly 20 is completed, the core combining carrier 610 is moved to a position where the feeding mechanism 210 can capture the core combining assembly 20. Therefore, the loading and unloading for the core carrier 610 are performed at different positions, so that the interference between the two components can be effectively avoided.

In addition, the core carrier 610 can also be turned, for example, by 90 degrees. When the battery cells 21 are aligned with the upper cover 22, the core combining carrier 610 makes the two paired battery cells 21 and the upper cover 22 in a horizontal state to facilitate alignment; after the core assembly 20 is assembled, the core carrier 610 is turned over 90 degrees to make the core assembly 20 in a vertical state. So, can make things convenient for feed mechanism 210 clamp to get and close core subassembly 20 to guarantee will close smooth material loading to welding carrier 120 of core subassembly 20.

It can be seen that the equipment 10 for assembling the battery core and the upper cover can realize the real-time preparation of the core assembly 20, and the prepared core assembly 20 is loaded onto the welding carrier 120 to complete the welding.

Further, the apparatus 10 for assembling a battery cell and an upper cover generally further includes a bottom plate 900, and the welding device 100, the first carrying device 200, the upper cover feeding device 300, the battery cell feeding device 400, the second carrying device 500, and the core combining transfer device 600 are all mounted on the bottom plate 900. In order to prevent the feeding processes of the upper cover 22 and the battery cells 21 from interfering with each other, the upper cover feeding device 300 and the battery cell feeding device 400 are respectively disposed at opposite ends of the bottom plate 900, i.e., at the left and right ends shown in fig. 1. The core combining carrier 610 is disposed between the top cover feeding device 300 and the cell feeding device 400.

The structure of the upper cover grabbing component 510 and the structure of the battery cell grabbing component 520 may be the same, and may also adopt the form of a sucker, a clamping jaw, etc. The second carrying device 500 further includes a second transmission mechanism 530, the second transmission mechanism 530 may also adopt the form of a transmission chain, and the upper cover grabbing component 510 and the battery cell grabbing component 520 are respectively disposed at two mutually independent driving ends of the second transmission mechanism 530. The second transmission mechanism 530 can drive the upper cover gripping assembly 510 and the cell gripping assembly 520 to move along the length direction of the base plate 900, i.e., the left-right direction shown in fig. 1. Therefore, the upper cover gripping assembly 510 and the cell gripping assembly 520 can smoothly transfer the gripped upper cover 22 and the cell 21 to the core combining carrier 610 under the driving of the second transmission mechanism 530.

It should be noted that, in other embodiments, the upper cover gripping assembly 510 and the cell gripping assembly 520 may also be respectively integrated with a multi-axis manipulator and other mechanisms capable of achieving position transfer, so that the upper cover gripping assembly 510 and the cell gripping assembly 520 may also achieve independent movement. In this case, the second transmission mechanism 530 may be omitted.

Specifically, in the present embodiment, the upper cover grabbing component 510 can grab a plurality of upper covers 22, and the cell grabbing component 520 can grab a plurality of cells 21, so as to assemble at least two core combining components 20 on the core combining carrier 610. It can be seen that at least two core-combining components 20 are simultaneously prepared and simultaneously fed to the welding carrier 120 for welding, so that the production efficiency can be further improved.

Specifically, the upper cap gripper assembly 510 is provided with two gripper cylinders that can act simultaneously to grip two upper caps 22 simultaneously. And the cell grasping assembly 520 is provided with four jaw cylinders, which can simultaneously move to simultaneously clamp the four upper cover cells 21. Therefore, two core combining components 20 can be assembled on the core combining carrier 610 at the same time.

In this embodiment, the apparatus 10 for assembling a battery cell and an upper cover further includes an upper cover detection device 700. The upper cover detecting device 700 includes a first conveying mechanism 710, a first carrier 720 and a detecting mechanism 730.

The first conveying mechanism 710 may adopt a transmission chain, a structure of a motor thread screw pair and a slider matching, and the like. The lid feeding device 300 can transport the lid 22 to the first carrier 720, and the first carrier 720 can drive the lid 22 to pass through the detection range of the detection mechanism 730 under the driving of the first transport mechanism 710. Specifically, the detection mechanism 730 may be a CCD camera, a scanner, or the like. The detection mechanism 730 can detect the upper cover 22 passing through the detection range to determine whether the upper cover 22 is qualified.

After the detection of the detection mechanism 730, the first conveying mechanism 710 continues to drive the first carrier 720 to move to a position where it can be grabbed by the cover grabbing component 510. If the upper lid 22 on the first carrier 720 is determined to be qualified, the upper lid grabbing component 510 grabs the upper lid 22 and transfers it to the core combining carrier 610 for assembling the core combining component 20; if the upper cover 22 on the first carrier 720 is determined to be unqualified, the upper cover grabbing component 510 transfers the grabbed upper cover 22 to the waste placement area to reject the unqualified upper cover 22.

Referring to fig. 3 and 4, in the present embodiment, the upper cover feeding device 300 includes a tray input mechanism 310, a tray output mechanism 320, a tray transferring mechanism 330, a second conveying mechanism 340, and an upper cover taking mechanism 350.

Specifically, the covers 22 are placed in trays, and a plurality of covers 22 may be placed in each tray. The tray input mechanism 310 and the tray output mechanism 320 are generally identical in structure, and only the conveying directions are opposite. The tray input mechanism 310 and the tray output mechanism 320 can both adopt the forms of a conveying belt, a transmission chain and the like, and can mainly drive the tray to feed. Tray input mechanism 310 can convey the tray with upper cover 22 to a position where it can be grasped by tray transfer mechanism 330, and tray transfer mechanism 330 can grasp the tray with upper cover 22.

The tray transfer mechanism 330 generally includes a driving member and a gripping member, wherein the driving member can drive the gripping member to move. After the grabbing piece grabs the tray, the transmission piece can move the grabbed tray towards the second conveying mechanism 340. The second conveying mechanism 340 includes a second conveying assembly 341 and a second carrier 342, and the tray transferring mechanism 330 can transfer the gripped tray to the second carrier 342 located at the tray feeding position. Under the driving of the second conveying assembly 341, the second carrier 342 can drive the tray to move between the tray feeding position and the upper cover material taking position. After receiving the tray full of the upper lids 22 at the tray loading position, the second carrier 342 is driven by the second conveyor 341 to move to the lid loading position.

The lid picking mechanism 350 may employ a robot with a gripper or a suction cup, which is capable of transferring the lid 22 located in the tray of the lid picking position to the first carrier 720 to enable detection of the lid 22. When the upper lid 22 in the tray is removed, the second conveying assembly 341 drives the second carrier 342 to return to the tray feeding position. Further, the tray transfer mechanism 330 can also transfer the tray located at the tray input position to the tray output mechanism 320.

The operation of the upper cover feeding device 300 is substantially as follows:

the tray filled with the upper lids 22 may be conveyed by the full tray material line 30 to the tray input mechanism 310, and the tray input mechanism 310 sequentially moves the tray filled with the upper lids 22 to below the tray transfer mechanism 330; next, the tray transferring mechanism 330 grabs the single tray and sequentially transfers the tray into the second carrier 342; after the second carrier 342 receives the tray filled with the upper lid 22, the second conveying assembly 341 operates to drive the second carrier 342 to move to the lid taking position; the lid picking mechanism 350 can sequentially transfer the lids 22 in the tray to the first carrier 720 for inspection until the lids 22 in the tray are completely picked.
