[0001] This utility model belongs to the technical field of sealant coating device, specifically relating to a sealant coating device for power batteries. Background Technology

[0002] Power batteries are rechargeable batteries that provide power for transportation vehicles (such as electric vehicles and hybrid vehicles) or large equipment. In order to prevent external moisture and corrosive media from entering and to ensure the airtightness of the battery pack, an automatic coating equipment is usually used during the production of power batteries. The spray gun is driven by a gantry to apply sealant in a quantitative manner along the sealing groove or edge of the battery shell to form a continuous and defect-free sealant layer.

[0003] However, in traditional sealant coating equipment, the battery casing is usually transported to a designated position on the equipment by a conveyor roller, and then a hydraulic cylinder drives a clamp to fix the casing. The hydraulic cylinder is usually directly fixed to the table with bolts. When the distance between the clamp and the casing exceeds the extension stroke of the hydraulic cylinder, the position of the hydraulic cylinder needs to be adjusted by repeatedly removing the bolts. The operation process is cumbersome and lacks flexibility. Summary of the Invention

[0004] The purpose of this utility model is to provide a sealant coating device for power batteries in order to solve the above problems. By installing a second hydraulic cylinder and a clamping plate between the first slide rail and the second slide rail, the position of the second hydraulic cylinder and the clamping plate is adjusted by pulling the pin on the slide rod, and the pin is engaged with the insertion hole to limit the position, thereby realizing the adjustment of the distance between the two clamping plates, which is convenient to adapt to battery shells of different sizes.

[0005] This utility model achieves the above objectives through the following technical solutions: A sealant coating device for power batteries includes a coating machine body with two coating guns mounted on it.

As a preferred embodiment, both ends of the connecting strip are fixedly connected to mounting plates, the mounting plates are fixedly connected to adjacent second hydraulic cylinders, and clamping plates are fixedly connected between the telescopic ends of the two second hydraulic cylinders.

[0006] As a preferred embodiment, a pin is slidably connected to the guide bar, and multiple insertion holes are provided on the slide rod, with the pin engaging with adjacent insertion holes.

[0007] As a preferred embodiment, a first tension spring is fixedly connected between the end of the slide rod and the guide bar, and a second tension spring is fixedly connected between the top of the pin and the guide bar.

[0008] As a preferred embodiment, the pin has a "T" shaped structure, and the plurality of sockets are equidistantly arranged.

[0009] As a preferred embodiment, the conveying structure includes a support frame, which is fixedly connected to the glue applicator body. A frame is fixedly connected to the support frame, and multiple rotating shafts are rotatably connected to the frame.

There is a motor 307, and the output shaft of the motor 307 is fixedly connected to one of the rotating shafts 303. When the motor 307 is started, the motor 307 drives the rotating shaft 303 and the rotating roller 304 on the frame 302 to rotate through the pulley 305 and the belt 306, which transports the power battery shell to the designated glue application position of the glue applicator body 1. The frame 302 is fixedly connected to the glue applicator body 1. When the glue applicator body 1 is started, the two glue applicators 2 apply a quantitative amount of sealant to the sealing groove or edge of the battery shell. After the glue application is completed, the glue applicator 2, the first hydraulic cylinder 405 and the second hydraulic cylinder 506 are closed in sequence, and then the rotating roller 304 transports the glued battery shell out of the device.

[0019] Please see Figures 1 to 6As shown, the conveying structure 3 is provided with a fixing structure 5, which includes a first slide rail 501. A first slide rail 501 and a second slide rail 503 are fixedly connected to both sides of the support frame 301. A slider 502 is slidably connected to both the first slide rail 501 and the second slide rail 503. A connecting strip 504 is fixedly connected between the two sliders 502 on the same side. A second hydraulic cylinder 506 is provided at both ends of the connecting strip 504. A slide rod 508 is fixedly connected to one of the second hydraulic cylinders 506. Two guide bars 509 are fixedly connected to the glue applicator body 1. The slide rod 508 is slidably connected to the adjacent guide bar 509. A pin 512 is slidably connected to the guide bar 509. Multiple insertion holes 511 are provided on the slide rod 508. The pin 512 engages with adjacent insertion holes 511. Mounting plates 505 are fixedly connected to both ends of the connecting bar 504. The mounting plates 505 are fixedly connected to adjacent second hydraulic cylinders 506. A clamping plate 507 is fixedly connected between the telescopic ends of the two second hydraulic cylinders 506. A first tension spring 510 is fixedly connected between the end of the slide rod 508 and the guide bar 509. A second tension spring 513 is fixedly connected between the top of the pin 512 and the guide bar 509. The pin 512 has a "T"-shaped structure, and the multiple insertion holes 511 are equidistantly arranged. First, pull the "T" on the guide bar 509 upwards... T-shaped pin 512 is disengaged from the insertion hole 511 of slide rod 508. Then slide rod 508 is released. Under the tension of the first tension spring 510, slide rod 508 drives connecting bar 504, mounting plate 505 and slider 502 to slide along the first slide rail 501 and second slide rail 503 on support frame 301. Adjust the distance between the second hydraulic cylinders 506 and clamping plates 507 on both sides to match the size of the battery casing. After adjustment, release pin 512 so that it is inserted into the corresponding insertion hole 511 under the action of second tension spring 513 to complete the limit. This makes it easy to adjust the distance between the two clamping plates 507 and to fix battery casings of different sizes. Then, start the second hydraulic cylinder 506 to push the clamping plates 507 to clamp the battery casing.

[0020] Please see Figures 1 to 6 As shown, the support frame 301 has a "U" shaped structure. A lifting structure 4 is installed on the support frame 301. The lifting structure 4 includes a connecting plate 401. Two connecting plates 401 are fixedly connected to the support frame 301. Two guide rods 402 are slidably connected to the connecting plates 401. A top plate 403 is fixedly connected between the two guide rods 402. A bracket 404 is fixedly connected to the bottom surface of the connecting plates 401. A first hydraulic cylinder 405 is fixedly connected to the bracket 404. The extension end of the first hydraulic cylinder 405 is fixedly connected to the top plate 403. The extension end of the first hydraulic cylinder 405 pushes the top plate 403 to rise along the guide rods 402, lifting the battery casing to a suitable adhesive application height. The bracket 404 is fixed to the bottom surface of the connecting plate 401 with bolts, ensuring strong stability.

[0021] In use, the motor 307 is started, and the motor 307 drives the rotating shaft 303 and rotating roller 304 on the frame 302 to rotate through the pulley 305 and belt 306, conveying the power battery casing to the designated glue application position on the glue coating machine body 1. Then, the "T"-shaped pin 512 on the guide bar 509 is pulled upward to disengage it from the insertion hole 511 of the slide rod 508. Then, the slide rod 508 is released. Under the tension of the first tension spring 510, the slide rod 508 drives the connecting bar 504, mounting plate 505 and slider 502 to slide along the first slide rail 501 and second slide rail 503 on the support frame 301. The distance between the second hydraulic cylinders 506 and clamping plates 507 on both sides is adjusted to fit the size of the battery casing. After adjustment, the pin 512 is released, causing it to be pulled upward by the second tension spring 506. Under the action of 13, the corresponding insertion hole 511 is inserted to complete the limit, which facilitates the adjustment of the distance between the two clamping plates 507 and the fixing of battery shells of different sizes. Then, the second hydraulic cylinder 506 is activated to push the clamping plate 507 to clamp the battery shell. After that, the first hydraulic cylinder 405 on the bracket 404 is activated, and its telescopic end pushes the top plate 403 to rise along the guide rod 402, raising the battery shell to a suitable glue application height. The bracket 404 is fixed to the bottom surface of the connecting plate 401 by bolts, which is very firm. Finally, the glue application machine body 1 is activated, and the two glue application guns 2 apply a certain amount of sealant to the sealing groove or edge of the battery shell. After the glue application is completed, the glue application guns 2, the first hydraulic cylinder 405 and the second hydraulic cylinder 506 are turned off in sequence, and then the glued battery shell is conveyed out of the device by the rotating roller 304.
