Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0028] Please refer to Figure 1-7 ;

[0029] A flexible cable pressing and welding device includes a rotary conveying mechanism 1, a pressing mechanism 3, and a laser welding mechanism 4. There are several fixtures 2 arranged in an annular array on the rotary conveying mechanism 1. An adjustable clamping assembly 21 is provided on the fixture 2. The clamping assembly 21 is used to clamp batteries of different sizes. An extension 22 is provided on the fixture 2, and a pressing assembly 23 for pressing the ear and the flexible cable together is provided on the extension 22. Preferably, after installing the battery, it is necessary to manually bend the end of the ear to facilitate the pressing of the ear and the flexible cable. The pressing mechanism 3 includes a fixed frame 31. A groove 32 is provided on the fixed frame 31. Two adjusting members 33 are movably installed on the groove 32. The two adjusting members 33 have the same structure. Specifically, a lifting assembly 34 is provided on the adjusting member 33, and a fixed block 35 is installed on the lifting assembly 34. A pressing member 36 for pressing the flexible cable and the ear is provided on the fixed block 35. The two pressing members 36 are respectively controlled to rise or fall independently through the two lifting assemblies 34, so that the pressing member 36 can press the flexible cable to prevent the flexible cable from warping and causing welding failure. At the same time, by adjusting the distance between the two adjusting members 33, the pressing member 36 can press the ears and flexible cables with different distances. The laser welding mechanism 4 is used to weld the ears and the flexible cables. Specifically, the laser emission lens 41 on the laser welding mechanism 4 emits laser light at the position where the ear and the flexible cable are in contact, thereby realizing the welding of the ear and the flexible cable.

[0030] Specifically, measure the distance between the two ears of the battery to be welded. Manually move the two adjusting members 33 to make the positions of the two pressing members 36 match the welding parts of the ears and the flexible cable. Then the operator installs the battery on the fixture 2, clamps the battery using the clamping assembly 21, and the pressing assembly 23 presses the ear and the flexible cable together. The lifting assembly 34 works to drive the pressing member 36 to descend. The pressing member 36 presses the flexible cable. The laser emission lens 41 emits laser light in sequence to weld the two ears and the flexible cable together. After welding is completed, the rotary conveying mechanism 1 rotates to rotate the subsequent battery to be welded to the pressing mechanism 3 to weld the ear and the flexible cable of this battery. This eliminates the need for manual participation in welding, improves work efficiency and welding quality, and eliminates the need for the operator to visually observe the welding, avoiding serious damage to the human eye caused by staring at the laser beam or reflected light during welding.

[0031] In this embodiment, through holes 361 are provided on both of the two pressing members 36. The through holes 361 are used for the laser light emitted by the laser emission lens 41 to pass through. The through holes 361 can also be used for the positioning of the laser emission lens to prevent the laser from hitting the outside and damaging other parts. Since intense visible light is generated during the laser welding process, if a person looks at it with the eyes, this visible light will cause a certain degree of damage to the human eye. The through holes 361 can block part of the light during the laser welding of the flexible cable and the ear, reducing the damage to the eyes.

[0032] In this embodiment, both of the two lifting components 34 include a cylinder three 341. A moving guide rail 342 is provided on the cylinder three 341. A slider 343 for mounting a fixing block 35 is provided on the moving guide rail 342. The lower end surface of the slider 343 is fixedly connected to the output end of the cylinder three 341. The lifting slider 343 is driven by the cylinder three 341 to move up and down, so that the pressing member 36 can press the wiring harness and the tab.

[0033] In this embodiment, locking bolts one 311 are provided on both sides of the fixing frame 31. The two locking bolts one 311 are respectively threadedly connected to the adjusting member 33. Adjusting holes three 312 corresponding to the adjusting member 33 are symmetrically provided on the fixing frame 31. Locking bolts two 313 are provided on both of the two adjusting holes three 312. The locking bolts two 313 pass through the adjusting holes three 312 and are threadedly connected to the adjusting member 33. The adjusting member 33 is locked and fixed through the cooperation of the locking bolts one 311 and the locking bolts two 313, preventing accidental contact with the adjusting member 33 and changing the position of the adjusting member 33, resulting in the need for readjustment. If the adjusting member 33 needs to be moved, only the locking bolt one 311 needs to be unscrewed from the adjusting member 33, and then the locking bolt two 313 is loosened. It should be noted that the locking bolt two 313 is not unscrewed, only loosened so that the adjusting member 33 can move. For example, if the locking bolt two 313 needs to be tightened 5 turns to lock the adjusting member 33, only 2 turns need to be turned in the reverse direction to loosen the locking bolt. After adjusting the position of the adjusting member 33, the locking bolt two 313 is tightened, and then the locking bolt one 311 is screwed into the adjusting member 33 to fix the adjusting member 33. Since both the fixing frame 31 and the locking bolt two are hard objects, the position will still shift when subjected to a large force. Therefore, in order to increase the friction coefficient of the contact surface, a rubber pad is added between the locking screw two and the fixing frame 31. The rubber pad can better fix the locking screw two and make it not easy to slide or rotate.

[0034] In this embodiment, the clamping component 21 includes a fixing member one 211 provided on one side of the jig 2. A limiting groove 212 communicated with the rotary conveying mechanism 1 is provided on the side of the jig 2 away from the fixing member one 211. A sliding member 213 is provided on the limiting groove 212. An adjusting hole one 214 is provided on the sliding member 213. The sliding member 213 is connected to the jig 2 by using a screw to pass through the adjusting hole one 214. The length of the limiting groove 212 is greater than the length of the sliding member 213. By loosening the screw, the sliding member 213 can freely move along the limiting groove 212 to adjust the distance between the sliding member 213 and the fixing member one 211, so as to fix batteries of different sizes.

[0035] In this embodiment, the pressing assembly 23 includes two positioning blocks 231 arranged at intervals. Adjusting holes II 232 are provided on both of the two positioning blocks 231. Both of the two positioning blocks 231 are connected to the jig 2 by using screws to pass through the adjusting holes II 232. By loosening the screws, the positions of the two positioning blocks 231 can be adjusted according to the spacing of the battery tabs. Avoidance positions 233 are provided on both of the two positioning blocks 231. The tabs extend out from the avoidance positions 233. A concave step 234 is provided on the side of the avoidance position 233 away from the jig 2. The end of the tab is bent at the position of the concave step 234 manually, so as to facilitate the pressing assembly 23 to press the cable and the tab tightly.

[0036] In addition, the pressing assembly 23 further includes a cylinder II 235. A fixing part II 236 is fixedly connected to the output end of the cylinder II 235. The fixing part II 236 drives the fixing part II 236 to move through the cylinder II 235. A pressing part 237 is installed on the fixing part II 236. The pressing part 237 is connected to the fixing part II 236 by using screws to pass through its side wall. When the fixing part II 236 moves, it drives the pressing part 237 to move together. A pressing part 238 corresponding to the concave step 234 is provided on the pressing part 237. Specifically, the two cables are respectively placed at the concave steps 234 of the two positioning blocks 231 and abutted against the tabs manually or by an external clamping device. Then the cylinder II 235 retracts. When the cylinder II 235 retracts, it drives the pressing part 238 to move towards the cable direction, so as to press the cable and the bent part of the tab tightly together.
