Description
Technical Field
[0001] This utility model relates to the field of assembly equipment technology, and in particular to a single-station four-in-one assembly machine for lithium battery caps. Background Technology
[0002] Battery cap production is a crucial step in lithium battery manufacturing. It typically consists of components such as an aluminum disc, insulating ring, tension plate, and sealing ring. The explosion-proof cap and top cap, after edge wrapping and shaping, are simply referred to as the aluminum disc. Cap production involves numerous steps, and product quality monitoring is essential during assembly. Traditional cap production assembly processes involve various types of assembly machines, such as edge wrapping and leveling machines, sealing ring assembly machines, and laser welding machines. These processes suffer from low efficiency in the transfer steps.
[0003] Furthermore, during the assembly process, the aluminum ingot is placed in a fixture. If misalignment occurs due to factors such as vibration, the aluminum ingot will deform during assembly, resulting in defective products. These defective products are usually in close contact with the fixture, making it difficult to separate them. Forcibly separating them can easily leave fragments of the defective product inside the fixture, thus affecting the normal use of the fixture.
[0004] Therefore, how to design a single-station four-in-one assembly machine for lithium battery caps to overcome the above-mentioned technical problems? Utility Model Content

[0039] This utility model provides a single-station four-in-one assembly machine 10 for lithium battery caps, such as... Figure 1 and Figure 2 As shown, it includes: a central transfer device 100, a feeding device 200, a welding device 300, a discharging device 400, and a retraction device 500.
[0040] Among them, such as Figure 2 and Figure 3 As shown, the central transfer device 100 includes a transfer turntable 110 and a drive module (not shown) for driving the transfer turntable 110. The transfer turntable 110 is provided with a plurality of fixtures 120. Preferably, the transfer turntable 110 has a plurality of through slots 111 evenly distributed along its edge. The number of fixtures 120 is the same as the number of through slots 111, and the plurality of fixtures 120 are respectively installed in the plurality of through slots 111.
[0041] The feeding device 200 includes: an aluminum disc feeding module 210, an insulating rubber ring feeding module 220, a tension piece feeding module 230, and a sealing ring feeding module 240, and the aluminum disc feeding module 210, the insulating rubber ring feeding module 220, the tension piece feeding module 230, and the sealing ring feeding module 240 are sequentially arranged around the transfer turntable 110;
[0042] The welding device 300 is located between the tension piece feeding module 230 and the sealing ring feeding module 240, and is used to weld the tension piece to the aluminum disc.
[0043] The feeding device 400 is used to feed the finished caps contained in the fixture 120.
[0044] The unloading device 500 is used to unload defective products contained in the fixture 120. Specifically, such as... Figure 4 and Figure 5 As shown, the unloading device 500 includes: a fixed bracket 510, a transverse cylinder 520, a slide 530, a limiting cleaning component 540, and a lifting component 550. The transverse cylinder 520 and the slide 530 are mounted on the fixed bracket 510, and the limiting cleaning component 540 is located on the piston rod of the transverse cylinder 520. The lifting component 550 is located on one side of the fixed bracket 510 and below the fixture 120 of the transfer turntable 110.
[0045] like Figure 5 As shown, the limiting cleaning assembly 540 includes an anti-detachment limiting plate 541 and a brush 542, with the brush 542 located at the front end of the anti-detachment limiting plate 541. Preferably, the anti-detachment limiting plate 541 has an upper baffle 5411 and a side baffle 5412, with the side baffle 5412 located on one side of the upper baffle 5411 in the displacement direction of the fixture 120; the brush 542 is located at the front end of the upper baffle 5411 and the side baffle 5412.
[0046] In this embodiment, as Figure 4 As shown, the lifting assembly 550 includes a longitudinal cylinder 551 and a lifting member 552 disposed on the piston rod of the longitudinal cylinder 551. The lifting member 552 is adapted to the fixture 120.
[0047] In this embodiment, the aluminum disc feeding module 210 is used to transport the aluminum disc into the fixture 120; the insulating rubber ring feeding module 220 is used to transport the insulating rubber ring 210 into the fixture 120 containing the aluminum disc and assemble the insulating rubber ring into the designated position of the aluminum disc; the tension piece feeding module 230 is used to transport the tension piece into the fixture 120 containing the aluminum disc and assemble the tension piece into the designated position of the aluminum disc; and the sealing ring feeding module 240 is used to transport the sealing ring into the fixture 120 containing the aluminum disc and place the sealing ring into the aluminum disc to complete the pre-assembly.
[0048] During assembly, multiple fixtures 120 are first installed into the through slots 111 of the transfer turntable 110. Then, the aluminum ingot feeding module 210 places the aluminum ingots into the corresponding fixtures 120. Subsequently, the drive module causes the transfer turntable 110 to rotate. The fixtures 120 sequentially pass through the aluminum ingot feeding module 210, the insulating rubber ring feeding module 220, the tension plate feeding module 230, and the sealing ring feeding module 240, completing the assembly of the insulating ring, tension plate, and sealing ring in sequence. Finally, after inspection, qualified caps are removed by the unloading device 400, while defective products are removed by the unloading device 500. Compared to existing technologies, the assembly machine 10 of this invention utilizes a central transfer device 100 to combine multiple types of devices together, thereby reducing the time for transferring aluminum ingots and improving the smoothness of assembly.
[0049] During assembly, the aluminum disc is placed in fixture 120. When misalignment occurs due to factors such as vibration, the aluminum disc will deform during assembly, resulting in a defective product. This defective product is usually in close contact with the fixture, making it difficult to separate from the fixture. Forcibly separating it can easily result in fragments of the defective product remaining in fixture 120, thus affecting the normal use of the fixture in subsequent steps. To address this, this invention designs a material ejection device 500.
[0050] The working principle of the unloading device 500 of this utility model will be explained below in conjunction with the above structure, with reference to... Figure 4 , Figure 5 and Figure 6 As shown:
[0051] During the unloading process, the fixture 120 containing the defective products moves to the unloading device 500 along with the transfer turntable 110, with the fixture 120 positioned between the limit cleaning assembly 540 and the lifting assembly 550.
[0052] First, the lateral cylinder 520 moves the limiting cleaning assembly 540 above the fixture 120. During this movement, the brush 542 sweeps across the fixture 120 and the defective products inside. The upper baffle 5411 of the anti-detachment limiting plate 541 moves directly above the fixture 120. Then, the longitudinal cylinder 551 of the lifting assembly 550 moves the lifting member 552 upward, thereby pushing the defective products inside the fixture 120 upward. During this process, the defective products may break into pieces. Finally, the lateral cylinder 520 drives the limiting cleaning assembly 540 back (e.g., ...). Figure 6 As shown, during the retraction process, brush 542 sweeps across fixture 120 again, which in turn sweeps defective products and fragments into chute 530; finally, longitudinal cylinder 551 causes lifting component 552 to move down, causing it to exit from fixture 120. At this point, fixture 120 is cleaned and can directly enter the next cycle.
[0053] Compared with the prior art, the unloading device 500 of this utility model can clean defective products and their debris from the fixture 120, thereby preventing debris from remaining in the fixture 120 and affecting the next cycle of material feeding. Moreover, before the lifting component 550 ejects the defective product, the limiting cleaning component 540 moves above the fixture 120. This not only prevents the defective product from jumping to other positions at the moment of ejection, but also cleans the surface of the fixture 120 and the defective product before ejection, avoiding debris causing ejection jamming.
[0054] In this embodiment, as Figure 2 and Figure 7 As shown, a sealing ring pressure device 600 is provided on one side of the central transfer device 100. The sealing ring pressure device 600 is located between the sealing ring feeding module 240 and the unloading device 400. The sealing ring pressure device 600 includes a pressing cylinder 610 and a lifting cylinder 620. When the fixture 120 moves below the sealing ring pressure device 240, the pressing cylinder 610 cooperates with the lifting cylinder 620 to clamp the aluminum cake in the fixture 120, thereby squeezing the sealing ring into the aluminum cake.
[0055] In this embodiment, as Figure 2 and Figure 7 As shown, the aluminum billet feeding module 210 includes: a vibratory feeder 211, a vertical vibrator 212, and a picking robot 213. The vertical vibrator 212 is connected to the outlet of the vibratory feeder 211. A preparation position 2121 and a picking position 2122 are formed on the vertical vibrator 212. The picking robot 213 moves between the picking position 2122 of the vertical vibrator 212 and the transfer turntable 110. During assembly, the aluminum billet is placed in the vibratory feeder 211, which moves the aluminum billet to the vertical vibrator 212. The picking robot 213 then grips the aluminum billet and transfers it from the vertical vibrator 212 to the fixture 120.
[0056] Correspondingly, the structures of the insulating rubber ring feeding module 220, the tension sheet feeding module 230, and the sealing ring feeding module 240 can also refer to the aluminum disc feeding module 210. Their structures are highly similar and belong to the prior art known to those skilled in the art, so they will not be described in detail here.
[0057] In this embodiment, as Figure 3As shown, a visual inspection device 700 is provided on one side of the central transfer device 100. The visual inspection device 700 includes a mounting bracket 710, a lens assembly 720, and a light source assembly 730. The lens assembly 720 and the light source assembly 730 are mounted on the mounting bracket 710. The lens assembly 720 is located above the fixture 120, and the light source assembly 730 provides illumination for the finished caps placed inside the fixture 120. During assembly, the visual inspection device 700 is used to photograph the caps inside the fixture 120 to determine whether they are qualified products, thereby prompting the unloading device 400 or the unloading device 500 to be activated.
[0058] In summary, this utility model provides a single-station four-in-one assembly machine 10 for lithium battery caps, which can improve the efficiency of the transfer process and quickly separate defective products from the fixture 120 to avoid fragment residue.
[0059] 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.
