Description

Technical Field

[0001] This invention belongs to the field of battery packaging technology, specifically, it relates to a core frame and molding equipment for battery encapsulation. Background Technology

[0002] With the explosive growth of the new energy vehicle and energy storage industries, the performance and environmental attributes of lithium battery core frames, as the core structural components for supporting and protecting battery cells, have attracted much attention. Traditional frames mostly adopt a one-piece solid or simple hollow design, which not only has the problems of large material usage and high weight, thus limiting the improvement of battery pack energy density, but also makes them prone to local damage during the expansion of battery cells during charging and discharging due to uneven distribution of structural rigidity.

[0003] Current frame production primarily uses virgin plastics, but the recycling rate of frames after lithium battery retirement is less than 30%, resulting in a large amount of plastic waste that not only wastes resources but also exacerbates environmental pressure. Although recycled plastic modification technologies are gradually maturing, their fluctuating mechanical properties make it difficult to directly adapt to the strength requirements of traditional frames, creating an industry pain point where there is an urgent need for material recycling but hindered application.

[0004] Against this backdrop, there is an urgent need to develop new frame structures that combine lightweight, high strength, and material compatibility. By optimizing the cavity shape and stress distribution, and adapting to the modified application of recycled plastics, we can achieve synergistic development of structural component performance, resource recycling, and cost reduction, which aligns with the core demands of the green transformation of the new energy industry.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0045] Example 1

[0046] like Figures 1 to 2 As shown, a battery potting core frame includes a frame body 100, a receiving cavity 101 is formed on the frame body 100, and a heat dissipation channel 102 is formed on the side of the receiving cavity 101.

[0047] The frame body 100 has a side plane 103 on its side, which is aligned with the receiving cavity 101. A topological structure is provided on the side plane 103, which is used to improve the overall structure of the frame body 100.

[0048] The topology includes a reinforcing groove 104 formed on the side of the side plane 103. The reinforcing groove 104 is composed of multiple consecutive hexagons and forms a honeycomb structure. The depth of the reinforcing groove 104 is 1 / 3 to 1 / 2 of the closest distance between the side plane 103 and the receiving cavity 101. The distance between two adjacent hexagons is 1 / 5 to 1 / 4 of the side length of the hexagon.

[0049] The honeycomb structure composed of hexagons not only enhances the strength of the frame body 100, but also saves materials and reduces costs.

[0050] Example 2

[0051] like Figure 2As shown, the topology includes heat dissipation holes 105 formed on the side plane 103. The heat dissipation holes 105 penetrate the side plane 103 and extend into the cavity 101. The centers of the heat dissipation holes 105 are evenly distributed at the equal division points in the vertical direction of the side plane 103. The ratio of the diameter of the heat dissipation hole 105 to the distance between two adjacent heat dissipation holes 105 is 4:5 to 1:1.

[0052] The heat dissipation hole 105 is connected to the interior of the receiving cavity 101, which can effectively enhance the heat dissipation capacity of the frame body 100.

[0053] Example 3

[0054] like Figures 3 to 11 As shown, a molding device forms a core frame for battery encapsulation by injection molding, including a support frame 200, and a support block 201 is fixedly installed on the side of the support frame 200;

[0055] Also includes:

[0056] The moving unit includes a first moving mechanism and a second moving mechanism. The first moving mechanism includes a first side template 303. A pushing component is provided on one side of the first side template 303. A locking mechanism is provided on the top of the first moving mechanism. The locking mechanism includes a push rod 305. A pressure plate 311 is fixedly installed at the end of the push rod 305. The locking mechanism also includes a first protruding rod 312 fixedly installed on the first side template 303. The first protruding rod 312 is adapted to the pressure plate 311.

[0057] The second moving mechanism includes a second side template 400, and a driving mechanism is provided at the bottom of the second side template 400. The second side template 400 and the first side template 303 form a closed quadrilateral.

[0058] like Figure 3 , Figure 8 , Figure 9 , Figure 11 As shown, in a specific embodiment, the pushing component includes a second hydraulic cylinder 300. A connecting seat 301 is fixedly mounted on the output end of the second hydraulic cylinder 300. A first insert rod 302 is fixedly mounted on one side of the connecting seat 301. One end of the first insert rod 302 movably passes through the support block 201 and the support frame 200 and is fixedly connected to the first side template 303. Side pressing members 313 are fixedly mounted on both sides of the first side template 303. The second hydraulic cylinder 300 pushes the first side template 303 to move via the first insert rod 302. In this configuration, when the second hydraulic cylinder 300 extends, it pushes the connecting seat 301 to move, thereby moving the first insert rod 302 and, during the movement, pushing the first side template 303 to move.

[0059] like Figure 8 , Figure 9 , Figure 10As shown, the locking mechanism further includes a fixed base 309. A support member 310 is fixedly installed on one side of the fixed base 309. A slide rod 308 is movably inserted into the support member 310. Connecting plates 307 are fixedly installed at both ends of the slide rod 308. One side of the connecting plate 307 is fixedly connected to the push rod 305. A first connecting frame 304 is fixedly installed on the top of the connecting base 301. The push rod 305 is movably connected to the first connecting frame 304. A first spring 306 is movably sleeved on the push rod 305. In this configuration, four connecting plates 307 are provided, and they are distributed in pairs at both ends of the slide rod 308. The first spring 306 serves as an energy storage device to push the push rod 305 to move.

[0060] like Figure 8 , Figure 9 , Figure 10 As shown, the locking mechanism further includes an unlocking component, which includes a locking rod 314 rotatably mounted on the top of the support frame 200. A pad 319 is fixedly mounted on one end of the locking rod 314, and a pad block 320 is fixedly mounted on the top of the support frame 200, with the pad block 320 aligned with the pad 319. A protrusion 317 is formed on the top of the locking rod 314. A stop bar 318 is fixedly mounted on the top of the connecting plate 307 at one end of the slide rod 308. A pressure block 316 is fixedly mounted on the first connecting frame 304, and the pressure block 316 is adapted to the locking rod 314. A second spring 315 is fixedly mounted on the bottom of the locking rod 314, and the bottom of the second spring 315 is fixedly connected to the support block 201. In this configuration, the second spring 315 provides elastic force to continuously subject the locking rod 314 to an upward thrust. The pad 319 and the pad block 320 support the locking rod 314, working together with the second spring 315 to keep the locking rod 314 in a horizontal state.

[0061] like Figure 5 , Figure 6 As shown, the driving mechanism further includes a second insert rod 402 that is movably inserted into the support frame 200 and the support block 201. The second insert rod 402 is fixedly connected to the second side template 400. A second protruding rod 401 is fixedly installed on the side of the second side template 400. The second protruding rod 401 is located at the bottom of the side pressure member 313 and fits against the side pressure member 313. Power components and limiting components are provided on both sides of the second insert rod 402. In this configuration, the side pressure member 313 abuts against the second protruding rod 401. When the second side template 400 is subjected to an upward external force, it is transmitted to the side pressure member 313 through the second protruding rod 401, so that the first side template 303 shares the external force.

[0062] like Figure 5As shown, the power assembly further includes a cylinder 405, with shafts 404 fixedly mounted at both ends of the cylinder 405. The limiting assembly includes a limiting frame 408 fixedly mounted at the bottom of the support frame 200. A limiting rod 406 is movably inserted into the limiting frame 408, and a limiting ring 407 is fixedly sleeved on the limiting rod 406. Both the limiting rod 406 and the shaft 404 are fixedly connected to the second insert rod 402 via the second connecting frame 403. In this configuration, when the cylinder 405 operates, it drives the shaft 404 to move. At this time, the limiting rod 406 moves accordingly, and during the movement, it drives the limiting ring 407 to move. When one end of the limiting ring 407 abuts against the limiting frame 408, the other end of the limiting ring 407 continues to move until both ends of the limiting ring 407 are in contact with the limiting frame 408.

[0063] like Figure 4 As shown, furthermore, a lifting unit is provided at the bottom of the support frame 200. The lifting unit includes a mold core 202, a tie rod 203 is fixedly installed on the top of the mold core 202, a fixing plate 204 is fixedly installed between the tops of two adjacent tie rods 203, and an electric cylinder 205 is installed on the top of the fixing plate 204. A support unit is provided at the bottom of the support frame 200, and the support unit includes a first hydraulic cylinder 207, with a bottom mold 206 fixedly installed at the output end of the first hydraulic cylinder 207. In this configuration, the first hydraulic cylinder 207 applies pressure to the bottom mold 206 to make it fit tightly against the first side template 303 and the second side template 400, preventing leakage during injection molding. Two adjacent mold cores 202 are connected by the fixing plate 204 to reduce the use of the electric cylinder 205.

[0064] A molding apparatus further includes a processor, which is equipped with a control system for controlling an electric cylinder 205. The control system includes:

[0065] The detection module acquires the initial load on the electric cylinder 205 when it is not being injected and the final load on the electric cylinder 205 when demolding. Based on the initial load and the final load, the module acquires the load difference of the electric cylinder 205, where the load difference represents the magnitude of the connection force between the cavity of the frame body 100 corresponding to the electric cylinder 205 and the mold core 202 when demolding.

[0066] A precision sensor is installed at the output end of the electric cylinder 205. The precision sensor is used to detect the load of the electric cylinder 205 and the motion state of the output end. The final load of the electric cylinder 205 is obtained based on the state corresponding to the critical point between the static and moving output end of the electric cylinder 205 during demolding.

[0067] The decision module includes sorting the connection forces between each chamber and the mold core 202 and controlling the electric cylinder 205 to contract in descending order;

[0068] During the demolding process of the mold core 202 controlled by the electric cylinder 205, it will continuously be subject to resistance from the already formed model. After reaching the critical state, the movement of the electric cylinder 205 will stop, and the electric cylinder 205 will be controlled to move in descending order based on the magnitude of the load difference, so that the mold core 202 with the larger connecting force will be demolded first, and the mold core 202 with the smaller connecting force will provide support for the mold core 202 with the larger connecting force.

[0069] The implementation principle of the battery core frame and molding equipment in this embodiment is as follows: During injection molding, the mold needs to be assembled first, the cylinder 405 is controlled to shrink, and the shaft 404 is moved during the shrinkage process. The shaft 404 drives the second insert rod 402 to move through the second connecting frame 403. The second insert rod 402 drives the second side template 400 to move. At the same time, the second insert rod 402 drives the limiting rod 406 to move through the second connecting frame 403. The limiting rod 406 drives the limiting ring 407 to move. When the limiting rings 407 on both sides abut against the limiting frame 408, the cylinder 405 is stopped. At this time, the second side templates 400 on both sides move to the designated position.

[0070] At this time, the second hydraulic cylinder 300 is activated. When the second hydraulic cylinder 300 is working, it drives the connecting seat 301 to move. The connecting seat 301 pushes the first insert rod 302 to move, so that the first side template 303 moves. When the connecting seat 301 moves, it drives the first connecting frame 304 to move, and compresses the first spring 306 during the movement. At the same time, the first connecting frame 304 drives the pressure block 316 to move. When the second hydraulic cylinder 300 stops moving, the first side template 303 abuts against the second side template 400, and the side pressure member 313 abuts against the second protrusion 401. At the same time, the pressure block 316 drives the locking rod 314 to rotate downward, so that the stop rod 318 disengages from the protrusion 317. At this time, the elastic force of the first spring 306 acts on the push rod 305, so that the push rod 305 moves and drives the pressure plate 311 to abut against the first protrusion 312.

[0071] Start the first hydraulic cylinder 207, which drives the bottom mold 206 to rise and seals the first side mold plate 303 and the second side mold plate 400. At the same time, the electric cylinder 205 works and drives the mold core 202 to fall through the pull rod 203. At this time, the injection molding work can be carried out.

[0072] When the injection molding is completed, the mold core 202 is withdrawn by controlling the electric cylinder 205, with priority given to withdrawing the mold core 202 that is more closely connected to the frame body 100.

[0073] After the mold core 202 is withdrawn, the second oil cylinder 300 is reset, which in turn drives the connecting seat 301 and the first connecting frame 304 to reset. During the reset process, the first connecting frame 304 drives the push rod 305 to reset through the connecting plate 307.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the protection scope of the present invention.
