Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, and in particular to a dual-station multi-head airtightness testing machine for cylindrical lithium battery caps. Background Technology

[0002] Cylindrical lithium batteries are a common type of lithium battery structure. To better protect cylindrical lithium batteries, explosion-proof combination caps are required. During the production and assembly process, the airtightness of the caps also needs to be tested to prevent the risk of battery leakage.

[0003] The existing Chinese utility model patent with the technical announcement number CN218002845U, entitled "Air Tightness Detection Device for Explosion-proof Combination Cap of Cylindrical Lithium Battery", discloses an air tightness detection device, which includes a cylinder body, a cap conveyor belt and a ten-loop pressure detector. The ten-loop pressure detector is equipped with a set pressure value, a detection pressure value, a no-leakage signal light and a leakage signal light. It can be connected to the equipment for full process inspection. The ten-loop pressure detector determines the type of air tightness and sorts it for air tightness detection.

[0004] However, in existing detection devices, the conveyor belt needs to be frequently paused during the detection process to ensure that the pressure detector has enough time to detect, which results in low detection efficiency.

[0005] Therefore, how to design a dual-station multi-head airtightness testing machine for cylindrical lithium battery caps to overcome the above-mentioned technical problems? Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a dual-station multi-head airtightness testing machine for cylindrical lithium battery caps, which can improve testing efficiency and achieve automatic sorting while realizing airtightness testing.

[0031] This utility model provides a dual-station multi-head airtightness testing machine 10 for cylindrical lithium battery caps, such as... Figure 1 and Figure 2 As shown, it includes: a base 100, a feeding device 200, a pressing device 300, and a picking device 400. The feeding device 200 is mounted on the base 100 and is used to transfer caps.

[0032] Among them, such as Figure 3 As shown, the feeding device 200 includes: a main conveying channel 210, a batch-shifting component 220, and auxiliary support fixtures 230. The batch-shifting component 220 is disposed on the main conveying channel 210, and the auxiliary support fixtures 230 are disposed on both sides of the main conveying channel 210. The batch-shifting component 220 is used to push the caps on the main conveying channel 210 toward the auxiliary support fixtures 230 on both sides. Preferably, the feeding device 200 also includes a vibrating plate 240, and the end of the main conveying channel 210 is connected to the discharge port of the vibrating plate 240.

[0033] like Figure 4 As shown, the pressing device 300 is used to detect the cap on the auxiliary support fixture 230;

[0034] like Figure 2As shown, the material handling device 400 is located on both sides of the feeding device 200 and is used to transfer the caps on the auxiliary support fixture 230. Figure 3 and Figure 4 As shown, the material handling device 400 includes: a translation module 410, a negative pressure detection component 420, a feeding conveyor belt 430, and a waste bin 440. The translation module 410 drives the negative pressure detection component 420 to move, the feeding conveyor belt 430 is used to place and transfer qualified caps, and the waste bin 440 is used to collect defective products.

[0035] In this embodiment, as Figure 5 As shown, the batch-shifting component 220 includes: a bracket 221, a horizontal cylinder 222, a slider 223, and a shifting beam 224. The bracket 221 is fixedly installed on one side of the main conveying channel 210, and the shifting beam 224 is installed on the slider 223. The horizontal cylinder 222 drives the slider 223 and the shifting beam 224 to move on the main conveying channel 210. The shifting beam 224 is provided with multiple shifting elements 2241, which are used to push the caps on the main conveying channel 210 toward the auxiliary support fixtures 230 on both sides.

[0036] Preferred, such as Figure 6 As shown, the main conveying channel 210 is provided with a lifting stop 211 and multiple spacers 212. The lifting stop 211 is located at the front end of the main conveying channel 210 in the forward direction. The multiple spacers 212 are located above the main conveying channel 210 and do not interfere with the transmission of the cap. An active channel is formed between two adjacent spacers 212, and the actuating member 2241 moves within the active channel.

[0037] like Figure 6 As shown, the auxiliary support fixture 230 is equipped with multiple inspection stations. Each inspection station includes an inspection position 231, an entry channel 232, and an exit channel 233. The entry channel 232 is close to the main conveyor channel 210, and the exit channel 233 is close to the waste bin 440. The entry channel 232 is funnel-shaped and aligned with the movable channel. When the actuating element 2241 moves, it pushes the cap on the main conveyor channel 210 through the movable channel and the entry channel 232, and it falls into the inspection station.

[0038] In this embodiment, as Figure 4 and Figure 7 As shown, the negative pressure detection assembly 420 includes: a gimbal 421, multiple negative pressure sliding tubes 422 and multiple detection heads 423. The multiple negative pressure sliding tubes 422 are slidably mounted on the gimbal 421, and each negative pressure sliding tube 422 has a detection head 423 at its end.

[0039] Preferred, such as Figure 4 and Figure 7As shown, the pressing device 300 includes: a support frame 310, multiple vertical cylinders 320 and a slide bar 330. The multiple vertical cylinders 320 are mounted on the support frame 310. The vertical cylinders 320 drive the slide bar 330 to move up and down and press it against the negative pressure slide tube 422.

[0040] The working principle of the dual-station multi-head airtightness testing machine 10 for cylindrical lithium battery caps of this utility model is as follows:

[0041] During assembly, the cap is conveyed onto the main conveyor channel 210, and then pushed towards the auxiliary support fixture 230 by the actuating element 2241 of the batch actuating component 220. The auxiliary support fixture 230 is located on both sides of the main conveyor channel 210, so the reciprocating motion of the actuating element 2241 can push the cap towards the auxiliary support fixtures 230 on both sides twice. The cap then enters the detection position 231 through the entry channel 232. Then, the pressing device 300 causes the negative pressure slide tube 422 and the detection head 423 to press down to the detection position 231, thereby performing an airtightness test on the cap. After the inspection is completed, the inspection head 423 forms a negative pressure. Caps that pass the airtightness test will be sucked up and transferred by the translation module 410 to the unloading conveyor belt 430. Defective products that fail the airtightness test will not be sucked up and will remain on the auxiliary support fixture 230. They will then be pushed to the exit channel 233 by the next cap entering the inspection position 231 and finally fall into the waste bin 440.

[0042] In summary, the dual-station multi-head airtightness testing machine 10 for cylindrical lithium battery caps of this invention can improve testing efficiency while achieving airtightness testing, and can also realize automatic sorting.

[0043] 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.
