Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, and in particular to a single-station line welding edge-sealing and leveling machine for lithium battery caps. Background Technology

[0002] Cylindrical lithium batteries are a common type of lithium battery structure. To better protect lithium batteries, explosion-proof combination caps are required. During the production and assembly process, the caps also need to be laser wire welded and the edges flattened.

[0003] The lithium battery cap assembly machine consists of a vibratory feeder, a turntable, an electrical system, and an interface display device. To achieve automation and improve efficiency, existing assembly equipment typically combines a laser wire welding device with an edge-wrapping and leveling device. However, since both the laser wire welding and edge-wrapping and leveling devices require specific fixtures, the cap transfer process relies solely on manual labor or a highly flexible robotic arm, resulting in high labor or robotic arm costs and low transfer efficiency.

[0004] Therefore, how to design a single-station line welding and edging leveling machine for lithium battery caps to overcome the above-mentioned technical problems? Utility Model Content

The structure of the second indexing plate component 310 is the same as that of the first indexing plate component 210, and the plurality of second fixtures 320 are evenly distributed on the second indexing plate component 310. Preferably, the turntable 211 has a plurality of through slots (not shown in the figure), which are evenly distributed on the edge of the turntable 211, and the plurality of first fixtures 220 and second fixtures 320 are installed in the plurality of through slots.

[0032] The transfer device 400 is installed between the welding device 200 and the edge-sealing and leveling device 300, such as Figure 5 As shown, the transfer device 400 includes: a support frame 410, a rotating crossbar 420, a negative pressure material handling component 430, a lifting assembly 440, and a pressing assembly 450. The support frame 410 is fixedly installed on the machine base 100. The rotating crossbar 420 is mounted on the support frame 410 via a rotating cylinder 460. Two negative pressure material handling components 430 are respectively provided at both ends of the rotating crossbar 420. The lifting assembly 440 is located above the first fixture 220, and the pressing assembly 450 is located above the second fixture 320.

[0033] In this embodiment, as Figure 5 As shown, the lifting assembly 440 includes a lifting cylinder 441 and a lifting push head 442 disposed on the piston rod of the lifting cylinder 441; the pressing assembly 450 includes a pressing cylinder 451 and a pressing slide rod 452, the pressing slide rod 452 pressing or disengaging from the negative pressure material handling component 430.

[0034] Preferred, such as Figure 5 As shown, the negative pressure material handling component 430 includes a head 431, a rod body 432, and a reset elastic element 433. The rod body 432 passes through a rotating crossbar 420, and the head 431 is located at the end of the rod body 432 and below the rotating crossbar 420. The reset elastic element 433 is located between the rod body 432 and the rotating crossbar 420, and is used to provide an upward reset elastic force for the rod body 432.

[0035] In this embodiment, as Figure 2 and Figure 3 As shown, the welding device 200 further includes: an explosion-proof sheet feeding component 230, a cover feeding component 240, and a wire welding component 250. The explosion-proof sheet feeding component 230, the cover feeding component 240, and the wire welding component 250 are installed around the first indexing plate component 210 and arranged sequentially along the rotation direction of the turntable 211. Figure 2 and Figure 4As shown, the edge-binding and leveling device 300 includes an edge-binding component 330, a leveling component 340, and a material-cutting component 350. The edge-binding component 330, the leveling component 340, and the material-cutting component 350 are arranged sequentially around the second indexing plate component 210 along the rotation direction of the turntable 211 of the second indexing plate component 210.

[0036] The working principle of the transfer device 400 will be explained below in conjunction with the above structure:

[0037] During operation, the cap is first placed on the first fixture 220. With the operation of the first indexing plate component 210, the cap completes the assembly of the explosion-proof sheet and the cap body and completes the wire welding. Then it moves to the station corresponding to the transfer device 400.

[0038] At this point, the lifting push head 442 of the lifting assembly 440 moves upward to push the cap out of the first fixture 220, and continues to lift until the cap contacts the head 431 of one of the negative pressure picking components 430. The negative pressure picking component 430 adsorbs or holds the cap, thus transferring the cap from the first fixture 220 to the negative pressure picking component 430. Subsequently, the rotating crossbar 420 rotates under the drive of the rotating cylinder 460, thereby moving the negative pressure picking component 430 and the cap above the second fixture 320. Then, the pressing slide bar 452 moves down and presses the negative pressure picking component 430, causing the negative pressure picking component 430 to overcome the elastic force of the reset elastic member 433 and move downward, thereby pressing the cap into the second fixture 320, thus completing the transfer of the cap from the first fixture 220 to the second fixture 320.

[0039] Preferred, such as Figure 6 As shown, the explosion-proof sheet feeding component 230 includes: a vibrating feeder 231, a linear vibrator 232, and a material handling robot 233. The linear vibrator 232 is connected to the outlet of the vibrating feeder 231. A material preparation position 2321 and a material handling position 2322 are formed on the linear vibrator 232. The material handling robot 233 moves between the material handling position 2322 of the linear vibrator 232 and the transfer turntable 211. During operation, the explosion-proof sheets accumulate in the vibrating feeder 231. The vibrating feeder 231 causes the explosion-proof sheets to move onto the linear vibrator 232. Then, the material handling robot 233 clamps the explosion-proof sheets and moves them from the material handling position 2322 to the first fixture 220 of the turntable 211.

[0040] In one embodiment, such as Figure 7As shown, the feeding component 350 includes an air blowing assembly 351, a material channel 352, and a collection box 353. The air blowing assembly 351 is located below the turntable 211 and includes a vertical cylinder 3511 and an air nozzle 3512 driven to rise and fall by the vertical cylinder 3511. The material channel 352 forms an inlet end 3521 and an outlet end 3522. The inlet end 3521 is located above the turntable 211 and the air blowing assembly 351, and the collection box 353 is located at the outlet end 3522 of the material channel 352. In use, the air nozzle 3512 of the air blowing assembly 351 blows air towards the second fixture 320, thereby using air pressure to blow the assembled caps into the material channel 352, and finally into the collection box 353.

[0041] In summary, the lithium battery cap single-station line welding and edging leveling machine 10 of this utility model can be conveniently transferred between two different fixtures, thereby improving work efficiency and reducing costs.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
