[0011] As a further optimization of the present invention, there are two control panels, which are symmetrically arranged at both ends of the second telescopic spring. Part of the control panel is arranged outside the fixed block, and the second telescopic spring slides inside the fixed block.
[0012] As a further optimization of the present invention, the connecting column and the connecting block have the same height, the first slider and the second slider have the same size, the first limit block and the second limit block are tightly attached to the upper end of the table, and the side section of the connecting block is rectangular.
[0013] As further optimized content of the present invention, wherein: S1: Startup of the automotive battery module integrated assembly line: After starting the new energy vehicle battery module integrated assembly line, the conveyor device will control the movement of the conveyor rack through its internal electric device, thereby controlling the directional movement of the workbench on the conveyor track. In the subsequent work process, the workbench can be continuously conveyed to the inside of the assembly mechanical device so that the assembly mechanical device can assemble the new energy vehicle battery module; S2: Placing the automotive battery module: After the workbench is powered on, the packaging shell of the automotive battery module can be prepared to be placed on the table. First, one side of the packaging shell of the automotive battery module presses the second limiting block in the second limiting mechanism, so that the second limiting block slides stably toward the fixed plate on the table through the connecting block fixedly connected thereto and the second slider fixedly connected to the connecting block.

At this time, the limiting rod can be pulled out of the sliding hole in the slide rod, releasing its fixed limiting effect on the slide rod. The user can control the slide rod to slide in the fixed plate and adjust the elastic compression force of the slide rod on the first telescopic spring through the circular plate, so that the first telescopic spring has sufficient elastic force to fix and limit the automobile battery module through the second limit block.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by setting up the design of the first limiting mechanism and the second limiting mechanism, the automobile battery module can be accurately positioned and fixed.

[0019] See also Figure 1-9 , the present invention provides a technical solution: A new energy vehicle battery module integrated assembly line and assembly method thereof, comprising an assembly mechanical device 1 and a conveying device 2. The assembly mechanical device 1 is fixedly connected to the outer side of the conveying device 2. The conveying device 2 is fixedly connected to the outer side of the conveying device 2. The conveying track 3 is meshedly connected to the outer side of the conveying track 3. The workbench 4 includes a table 41. The outer side of the table 41 is fixedly connected to a first limiting mechanism 42. The outer side of the table 41 is fixedly connected to a second limiting mechanism 43. The first limiting mechanism 42 includes a fixing frame 421. A screw rod 422 is rotatably connected to the inner side of the fixing frame 421. One end of the screw rod 422 is fixedly connected to a gear 423. The gear 423 is meshed with a threaded column 424. The upper end of the threaded column 424 is fixedly connected to a knob 425. A first limiting block 426 is spirally connected to the outer side of the screw rod 422. A connecting column 427 is fixedly connected to the outer side of the first limiting block 426. The lower end of the connecting column 427 is fixedly connected to a first slider 428; The second limiting mechanism 43 includes a fixing plate 431. A sliding rod 432 is slidably connected to the inner side of the fixing plate 431. One end of the sliding rod 432 is fixedly connected to a circular plate 433. A first telescopic spring 434 is fixedly connected to the outer side of the circular plate 433. A connecting plate 435 is fixedly connected to the outer side of the first telescopic spring 434. A second limiting block 436 is fixedly connected to the outer side of the connecting plate 435. A connecting square 437 is fixedly connected to the outer side of the second limiting block 436. The lower end of the connecting square 437 is fixedly connected to a second slider 438. A force control mechanism 439 is fixedly connected to the outer side of the fixing plate 431; The force control mechanism 439 includes a fixing block 4391. A control plate 4392 is slidably connected to the inner side of the fixing block 4391. A limiting clamping rod 4393 is fixedly connected to the outer side of the control plate 4392. A second telescopic spring 4394 is fixedly connected to the outer side of the control plate 4392.
[0020] As a further technical solution of this scheme, three sliding grooves are formed in the inner side of the table board 41. The sliding grooves formed in the inner side of the table board 41 are distributed in a "pin" shape. The connecting column 427, the first slider 428, the connecting square 437 and the second slider 438 slide on the inner side of the table board 41. This design improves the utilization rate and flexibility of the table board 41, enabling the components in the assembly process to be efficiently positioned and moved on the table board 41.
[0021] As a further technical solution of this scheme, there are two screw rods 422. The screw rods 422 are symmetrically arranged on the outer side of the same gear 423. The screw rods 422 and the threaded column 424 are perpendicular to each other. The screw rods 422 are arranged directly above the table board 41. The symmetrical design of the screw rods 422 and the gear 423 ensures the balance and coordination of the assembly line, improving the stability and synchronism of the assembly process.
[0022] As a further technical solution of this scheme, the gear 423 is arranged directly below the fixing frame 421. The gear 423 has a structure with a larger diameter in the middle and smaller diameters at both ends. The maximum rotation range radius of the gear 423 is below the arc radius of the arc surface end of the first limiting block 426. The gear 423 does not come into contact with the table board 41 at all. The non-contact design of the gear 423 reduces the friction with the table board 41, extends the service life of the assembly line, and at the same time reduces noise and maintenance costs.
[0023] As a technical solution for further implementation of this scheme, the upper end of the threaded column 424 is an inward concave arc structure. The threaded column 424 rotates in a concave hole opened on the inner side of the table 41. The threaded column 424 rotates on the inner side of the fixing frame 421. The knob 425 fixedly connected to the upper end of the threaded column 424 is arranged above the fixing frame 421. The concave arc structure of the threaded column 424 and the rotation on the inner side of the table 41 provide a smooth adjustment mechanism, so that the assembly line can accurately control the position of the components.
[0024] As a technical solution for further implementation of this scheme, there are two connecting plates 435, which are symmetrically arranged on both sides of the second limit block 436. The connecting plates 435 and the inner side of the second limit block 436 are on the same horizontal plane. The connecting plates 435 and the fixed plates 431 are parallel to each other. The symmetrical arrangement of the connecting plates 435 on both sides of the second limit block 436 enhances the symmetry and balance of the assembly line and improves the accuracy and stability of the assembly process.
[0025] As a technical solution for further implementation of this scheme, the side cross-section of the sliding rod 432 is rectangular, and a number of equidistant sliding holes are opened on the inner side of the sliding rod 432. The limiting rod 4393 slides in the sliding holes on the inner side of the sliding rod 432. The sliding rod 432 is symmetrically arranged on both sides of the fixed block 4391. The rectangular side cross-section and the inner sliding hole design of the sliding rod 432 provide a stable sliding path for the limiting rod 4393, thereby enhancing the flexibility and adjustment ability of the assembly line.
[0026] As a technical solution for further implementation of this scheme, there are two control plates 4392. The control plates 4392 are symmetrically arranged at both ends of the second telescopic spring 4394. Part of the control plate 4392 is arranged on the outside of the fixed block 4391, and the second telescopic spring 4394 slides on the inside of the fixed block 4391. The symmetrical setting of the control plate 4392 and the cooperation of the second telescopic spring 4394 provide a flexible adjustment mechanism, so that the assembly line can adjust the elastic limiting force according to different needs.
[0027] As a technical solution for further implementation of this scheme, the connecting column 427 and the connecting block 437 have the same height, the first slider 428 and the second slider 438 have the same size, the first limit block 426 and the second limit block 436 are tightly attached to the upper end of the table 41, the side section of the connecting block 437 is rectangular, the connecting column 427 and the connecting block 437 have the same height, and the first slider 428 and the second slider 438 have the same size. This consistent design simplifies the structure of the assembly line and improves the efficiency and accuracy of assembly.
[0028] As a technical solution for further implementation of this plan, S1: Starting the automotive battery module integrated assembly line: After starting the new energy vehicle battery module integrated assembly line, the conveyor device 2 controls the movement of the conveyor rack through its internal electric device, thereby controlling the directional movement of the workbench 4 on the conveyor track 3. In the subsequent working process, the workbench 4 can be continuously conveyed to the inside of the assembly mechanical device 1 so that the assembly mechanical device 1 can assemble the new energy vehicle battery module; S2: Placing the automobile battery module: After the workbench 4 is powered on, the packaging shell of the automobile battery module can be prepared to be placed on the table 41. First, one side of the packaging shell of the automobile battery module squeezes the second limiting block 436 in the second limiting mechanism 43, so that the second limiting block 436 slides stably toward the fixed plate 431 on the table 41 through the connecting block 437 fixedly connected to it and the second slider 438 fixedly connected to the connecting block 437. At this time, the second limiting block 436 can exert a certain compressive force on the first telescopic spring 434 through the two connecting plates 435 fixedly connected to its outer side, so that the packaging shell of the automobile battery module can be horizontally placed between a second limiting block 436 and two first limiting blocks 426; S3: Centerline positioning limit of automobile battery module: rotating the knob 425 above the fixing frame 421 causes the knob 425 to drive the threaded column 424 to which it is fixed to slide stably on the inner side of the fixing frame 421, so that the threaded column 424 can drive the gear 423 below the fixing frame 421 to rotate, and then the gear 423 drives the screw rods 422 fixedly connected at both ends to rotate stably, and the stable rotation of the screw rod 422 can control the first limit block 426 to which it is spirally connected to move synchronously toward the direction of the fixing frame 421 located at the centerline position of the table 41, and the first limit block 426 slides stably on the table 41 through the connecting column 427 to which it is fixed and the first slider 428 fixedly connected to the connecting column 427 until the two first limit blocks 426 fix and limit the packaging shell of the automobile battery module, so that the subsequent device can facilitate the stable assembly of the automobile battery module under the action of the conveying device 2; S4: Adjustment of the elastic limiting force of the automobile battery module: When it is necessary to adjust the elastic thrust of the first telescopic spring 434 according to the position of the second limit block 436, the two control plates 4392 can be controlled to move toward each other, so that the two control plates 4392 can compress the second telescopic spring 4394 therebetween, so that the limiting clamping rod 4393 fixedly connected to the two control plates 4392 can be slid and retracted into the inner side of the fixed block 4391. At this time, the limiting clamping rod 4393 can be withdrawn from the sliding hole in the sliding rod 432, releasing its fixed limiting effect on the sliding rod 432. The user can control the sliding rod 432 to slide in the fixed plate 431 and adjust the elastic compressing force of the sliding rod 432 on the first telescopic spring 434 through the circular plate 433, so that the first telescopic spring 434 has sufficient elastic force to fix and limit the automobile battery module through the second limit block 436; The innovative design of this integrated assembly line for new energy vehicle battery modules significantly improves assembly precision and stability. Its precise first and second restraining mechanisms (42, 43) ensure accurate positioning and fixation of the battery modules during assembly, reducing assembly errors and rework, and improving product quality. The design's flexibility and adjustability allow for adjustment of the elastic restraining force based on the size and model of the battery modules, enhancing the assembly line's adaptability and ease of operation. Overall, this assembly line, through its automated and intelligent features, optimizes the production process and provides strong support for the efficient and precise assembly of new energy vehicle battery modules.

At this time, the second limiting block (436) can exert a certain compressive force on the first telescopic spring (434) through the two connecting plates (435) fixedly connected to its outer side; S3: Centerline positioning restriction of the automobile battery module: rotating the knob (425) above the fixing frame (421) causes the knob (425) to drive the threaded column (424) fixedly connected thereto to slide stably inside the fixing frame (421), so that the threaded column (424) can drive the gear (423) below the fixing frame (421) to rotate, and then the gear (423) drives the screw rod (422) fixedly connected at both ends thereof to rotate stably, and the stable rotation of the screw rod (422) can control the first limit block (426) to which it is spirally connected to move synchronously toward the direction of the fixing frame (421) located at the centerline position of the table (41), and the first limit block (426) slides stably on the table (41) through the connecting column (427) fixedly connected thereto and the first slider (428) fixedly connected to the connecting column (427) until the two first limit blocks (426) fix and restrict the packaging shell of the automobile battery module; S4: Adjustment of the elastic limiting force of the automobile battery module: When it is necessary to adjust the elastic thrust of the first telescopic spring (434) according to the position of the second limit block (436), the two control plates (4392) can be controlled to move toward each other, and the two control plates (4392) can compress the second telescopic spring (4394) therebetween, so that the limiting rods (4393) fixedly connected to the two control plates (4392) can be slid and retracted into the inner side of the fixed block (4391). At this time, the limiting rod (4393) can be withdrawn from the sliding hole in the slide rod (432), releasing its fixed limiting effect on the slide rod (432). The user can then control the slide rod (432) to slide in the fixed plate (431) and adjust the elastic compressive force of the slide rod (432) on the first telescopic spring (434) through the circular plate (433).
