Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle battery module assembly, and particularly relates to a module strip limiting and perforating tooling. Background Art

[0002] At present, in the rapid development of new energy vehicles, new energy vehicle models are constantly being developed, passenger vehicles are becoming increasingly mature, and commercial vehicles are also being continuously promoted and implemented. However, compared with the whole vehicle, higher requirements are put forward for the energy density of the battery system. There are two ways to increase the battery energy density: one is to increase the specific energy of a single cell; the other is to lighten the structure of the battery pack. Increasing the specific energy of a single cell is difficult in terms of technology, has a long R & D cycle, and requires a large amount of capital investment. In contrast, it is easier to lighten the structure of the battery pack.

[0003] The lightweight of the module shows a trend of large modules, not only reducing the weight of the module end plate, but also releasing the space size. However, long modules and large modules also face structural problems; during the production and assembly process, due to the increase in the module length and the relatively weak overall stiffness of the long module, deformation is likely to occur during the hoisting process.

[0004] At present, the fixation of the middle end plate of the long module mostly relies on manual positioning or traditional jigs, and there are the following problems: Insufficient accuracy: Manual operation is likely to cause deviation between the strip and the module hole position, leading to the risk of interference; Low efficiency: Traditional tooling needs to be adjusted repeatedly and is difficult to meet the rigidity requirements of ultra-long modules.

[0005] In summary, the applicant proposes a module strip limiting and perforating tooling. Summary of the Invention

[0006] The purpose of the present invention is to provide a module strip limiting and perforating tooling to save labor costs and improve network security. To achieve the above technical purpose, the technical solution of the present invention is as follows: A module strip limiting and perforating tooling includes a lower box body. A battery module is arranged inside the lower box body. A support structure is installed on the front side of the lower box body, and a module pressing plate is slidably arranged on the support structure.

[0007] Further, the lower box body is composed of a front beam of the box body, a rear beam of the box body, two groups of side beams of the box body, and a bottom plate. The lower box body is divided into a large interval and a small interval by a partition board. A cross beam is installed at the bottom of the large interval of the lower box body, and a cross plate is installed at the bottom of the small interval of the lower box body.

[0008] Further, on one side of the front beam of the box body and the rear beam of the box body that are away from each other, mounting plates are fixedly connected, and lifting lugs are uniformly arranged on the mounting plates. An external support of the box is installed on the side beam of the box body of the lower box body.

[0009] Furthermore, a limiting hole for the module pressing plate to penetrate is formed in the middle of the battery module.

[0010] Furthermore, the supporting structure includes a magnetic base arranged on the mounting plate, an L-shaped frame fixedly connected to the magnetic base through an inclined plate, and guide rollers uniformly arranged on the L-shaped frame.

[0011] Furthermore, the top of the I-shaped frame is fixedly connected to the L-shaped frame, and guide blocks are installed on some sides of the L-shaped frame.

[0012] After improvement, the present invention further has the following beneficial effects: 1. The present invention can be flexibly placed in a suitable position through the supporting structure as the basic support of the entire tooling, and then guide and support the module pressing plate to realize the installation of the middle end plate module pressing strip of the ultra-long module. Moreover, the supporting structure can be quickly disassembled and assembled to adapt to different specifications of modules.

[0013] 2. The supporting structure adopts a simple triangular frame structure, providing a stable support frame for the entire tooling, ensuring the stability of the tooling during the pressing strip installation process, facilitating the accurate progress of subsequent operations. In addition, with a simple structure, it is also easy to manufacture and install, reducing the production cost.

[0014] 3. The supporting structure uses high-strength magnets to achieve non-contact fixation, avoiding scratching the surface of the module. And using magnets for fixed limit can make the tooling more convenient and easy to operate during installation and disassembly; through the adsorption force of the magnets, the tooling can be quickly fixed in the required position, and at the same time, when adjustment or disassembly is needed, only the adsorption force of the magnets needs to be overcome, greatly improving the operation efficiency.

[0015] 4. The L-shaped frame is used to limit the workpiece. This frame can achieve simple and reliable limitation of the workpiece, ensuring the accurate position of the workpiece during installation; at the same time, the design of the L-shaped frame makes the operation of loading and unloading parts highly operable, facilitating workers to operate and improving the production efficiency.

[0016] 5. The present invention combines the L-shaped frame and magnetic fixation to ensure the accuracy and stability of the pressing strip installation, effectively solving the problems of interference and disturbance between the pressing strip and the module, and avoiding damage to the module.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] As Figures 1 to 5 shown, a module pressing strip limiting and perforating tooling includes a lower box body 1, a battery module 2 is arranged inside the lower box body 1, a support structure 3 is installed on the front side of the lower box body 1, and a module pressing plate 4 is slidably arranged on the support structure 3.

[0025] It should be noted that in this solution, the module pressing plate 4 accurately penetrates into the middle of the battery module 2 through the support structure 3 to fix the middle end plate of the battery module 2.

[0026] The lower box body 1 is composed of a box body front beam, a box body rear beam, two groups of box body side beams and a bottom plate. The lower box body 1 is divided into a large interval and a small interval by a partition board 5. A cross beam 6 is installed at the bottom of the large interval of the lower box body 1, and a horizontal board 7 is installed at the bottom of the small interval of the lower box body 1.

[0027] It should be noted that the partition board 5 can be adjusted horizontally and can be flexibly adjusted according to the width of the battery module 2, so as to adapt to different sizes of battery modules 2. The cross beam 6 and the horizontal board 7 are both for strengthening the supporting force for the battery module 2.

[0028] On the separated sides of the box body front beam and the box body rear beam of the lower box body 1, mounting plates 8 are fixedly connected, lifting lugs 9 are arranged in a uniform array on the mounting plates 8, and an external box support is installed on the box body side beam of the lower box body 1.

[0029] A limiting hole for the module pressing plate 4 to penetrate is opened in the middle of the battery module 2.

[0030] It should be noted that traditional tooling requires multiple adjustments and is difficult to adapt to the rigidity requirements of ultra-long modules. In this solution, the limiting hole of the battery module 2 is opened in the upper half of the middle to ensure that the rigidity of the battery module 2 is enhanced to the greatest extent after the module pressing plate 4 enters.

[0031] The support structure 3 includes a magnetic base 31 disposed on the mounting plate 8 , an L-shaped frame 33 fixedly connected to the magnetic base 31 via an inclined plate 32 , and guide rollers 34 evenly arranged on the L-shaped frame 33 .

[0032] It should be noted that the magnetic base 31, the inclined plate 32 and the L-shaped frame 33 form a tripod structure to ensure the stability of the movement of the module pressing plate 4. The magnetic base 31 is composed of a base and two groups of permanent magnets installed on both sides. The on-off is controlled by a magnetic switch, and the adsorption force is ≥50N / group to ensure that the tooling and the module are reliably fixed. The L-shaped frame 33 is provided with a longitudinal guide groove for setting the guide roller 34. The groove width is 0.5mm larger than the width of the layer, and the depth is 10mm, which limits the vertical shaking of the layer. In addition, the tripod structure can be quickly disassembled and assembled, and can be adapted to modules of different specifications, providing a stable support frame for the entire tooling, ensuring the stability of the tooling during the installation of the pressure strip, and facilitating the precise implementation of subsequent operations; through the magnetic limit and L-shaped frame 33 design, the tooling can be quickly fixed in the required position, and when adjustment or disassembly is required, it is only necessary to overcome the adsorption force of the magnet, which greatly improves the operating efficiency; and solves the problems of offset and interference during the installation of the pressure strip.

[0033] The top of the I-shaped frame 35 is fixedly connected to the L-shaped frame 33 , and a guide block 36 is installed on a part of the side of the L-shaped frame 33 .

[0034] It should be noted that the I-shaped frame 35 is used to supplement the height difference between the magnetic base 31 and the L-shaped frame 33 , and the guide block 36 is arranged in a trapezoidal shape to guide the insertion direction of the module pressing plate 4 .

[0035] The specific working method is described below with specific embodiments: Example 1

[0036] First, place the support structure 3 at a suitable position as the basic support for the entire tooling, then use the magnetic base 31 to fix the L-shaped frame 33 on the box body, and by adjusting the position of the magnetic base 31, make the L-shaped frame 33 accurately align with the position of the middle hole of the battery module 2 to achieve preliminary positioning of the workpiece; then, place the module pressure strip 4 on the L-shaped frame 33, and through the limiting effect of the L-shaped frame 33, ensure that the module pressure strip 4 can be accurately aligned with the middle hole of the module; finally, use external force to pass the module pressure strip 4 through the middle hole of the module pressure strip 4 to complete the fixed installation of the middle end plate of the battery module 2. Example 2

[0037] During the installation process, first attach the base of the magnetic seat 31 to the side wall of the module, activate the magnetic switch to adsorb and fix it, which avoids the problems of inaccurate installation of the pressure strip or damage to the module caused by the shaking of the tooling; after the installation is completed, turn off the magnetic switch, and the tooling and the module can be quickly separated, and the single-cycle time consumption ≤ 2 minutes.

[0038] The present invention has been described exemplarily in combination with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above-mentioned concept and technical solution of the present invention are directly applied to other occasions, they are all within the protection scope of the present invention.
