Description

Technical Field

[0001] The present invention relates to the field of filtration technology, and in particular to a composite buffer foam for a new energy power battery module and a compression molding process thereof. Background Art

[0002] Composite buffer foam for new energy power battery modules is a multifunctional buffer material designed specifically for power battery modules. It is mainly used to solve the protection needs of batteries in scenarios such as vibration, impact, thermal management, and insulation.

[0003] In traditional foam molding processes, the demolding process often uses independent control. Since the molding and demolding mechanisms are relatively independent, it is difficult to ensure high synchronization between the two in actual operation. After the foam is formed, if the demolding action is slow to respond, the foam may stay in the mold too long, resulting in strong adhesion between the mold and the foam, which leads to frequent mold sticking. In addition, independent control is prone to uneven demolding force, making it difficult for some foam to be completely ejected from the mold, which greatly affects production efficiency and product quality stability.

[0004] At the same time, during the continuous molding production process, the mold will generate a lot of heat due to repeated high pressure and friction with the foam. If the heat cannot be dissipated in time, the mold temperature will continue to rise. On the one hand, it will have a serious impact on the quality of the foam in subsequent molding. The foam may degrade due to high temperature, resulting in a significant decrease in its cushioning performance; on the other hand, high temperature will also cause the foam to adhere to the mold, which not only increases the difficulty of demolding, but also easily leaves defects on the foam surface, affecting its appearance quality. In view of this, we propose a composite cushioning foam and its molding process for new energy power battery modules. Summary of the Invention

[0005] The purpose of the present invention is to provide a composite buffer foam for new energy power battery modules and its molding process, so as to solve the problems of asynchronous action, easy mold jamming and uneven demolding in the traditional foam molding process proposed in the above background technology due to the independence of the molding and demolding mechanisms in the demolding link; the heat of the mold is difficult to dissipate during continuous production, resulting in reduced foam quality and difficulty in demolding.

[0006] In order to solve the above technical problems, one of the purposes of the present invention is to provide a composite buffer foam molding process for new energy power battery modules, comprising

[0007] The first step is to place the pre-prepared composite cushioning foam on the conveyor;

[0008] In the second step, the hydraulically driven molding mechanism starts to operate, applying pressure to the composite cushioning foam on the conveyor, molding it into a specific foldable shape;

[0009] Step 3: After the composite cushioning foam is molded, the demoulding mechanism intervenes to smoothly remove the molded foam from the mold.

[0010] The molding mechanism is driven by hydraulic pressure to precisely mold the composite cushioning foam into a specific foldable structure. During the linear displacement of the molding mechanism, the elastic linkage structure built into the molding mechanism synchronously drives the demoulding mechanism to move in the opposite direction to achieve efficient demoulding. In addition, when the demoulding mechanism ejects the molded composite cushioning foam, the airflow generated by the movement causes the air inside the molding mechanism to form a forced convection circulation to achieve cooling.

[0011] The beneficial effects of the present invention are:

[0012] 1. In this invention, when the molding mechanism rises, the first rack fixed to the inner cylinder moves downward, driving the gear to rotate, which in turn drives the second rack to move horizontally. Ultimately, the power is transmitted to the piston through the moving rod, causing the piston to move within the cylinder cavity, thereby pushing the molded foam out of the mold. This demolding process is highly synchronized and responsive, avoiding the problems of mold sticking and incomplete demolding that may occur in traditional independent control methods, significantly improving demolding efficiency and product consistency.

[0013] At the same time, the mechanical movement generated during the demoulding process also drives the air flow. The formed local airflow enters the interior of the molding mechanism, promoting air circulation convection, effectively reducing the temperature of the mold area, preventing heat accumulation from affecting the subsequent molding quality, achieving the dual effects of demoulding and cooling, and enhancing the stability and safety of the equipment's continuous operation.

[0014] 2. In the present invention, the piston of the demoulding mechanism moves downward driven by the moving rod to eject the foam. This movement process causes strong airflow disturbance inside the molding mechanism, which drives the air to flow rapidly in the molding mold, forming a forced convection cycle. The high-speed flowing air is in full contact with the mold wall, and the heat accumulated in the mold during the molding process is quickly taken away by convection heat exchange, thereby accelerating the heat dissipation of the mold and reducing the mold temperature. On the one hand, it avoids the problems of foam degradation and adhesion to the mold due to high temperature, thereby ensuring the cushioning performance and appearance quality of the foam; on the other hand, it reduces the thermal fatigue and wear of the mold caused by long-term high temperature, thereby extending the service life of the mold.

[0015] As a further improvement of the present technical solution, both sides of the conveyor are fixedly connected with a fixed plate for installing the conveyor, one side of the fixed plate is fixedly connected with a hydraulic lifting rod, the molding mechanism includes a forming mold fixedly connected to the bottom of one end of the hydraulic lifting rod, and both sides of the forming mold are provided with through holes for moving the demolding mechanism, and the interior of the forming mold is fixedly connected with a lower pressure plate, and the height of the lower pressure plate is lower than the height of the two sides of the forming mold.

[0016] The beneficial effect of adopting the above further solution is that the hydraulically driven molding mechanism can quickly and accurately press the foam into a foldable shape, and the built-in elastic linkage structure enables the demolding mechanism to automatically move in the opposite direction after the molding is completed, and the mold can be efficiently demolded without additional operation, greatly shortening the production cycle.

[0017] As a further improvement of the present technical solution, the top of one end of the hydraulic lifting rod is fixedly connected to an inner cylinder, the outer wall of one end of the inner cylinder is fixedly connected to a protrusion block, and a buffer spring is sleeved on the inner cylinder, the top of the buffer spring is fixedly connected to a sleeve, and sliding grooves are provided on both sides of the sleeve. A bracket is fixedly connected to the sleeve, and the bottom end of the bracket is connected to the fixed plate.

[0018] The beneficial effect of adopting the above further solution is that the raised blocks on the outer wall of the inner tube cooperate with the sliding grooves on both sides of the sleeve to limit the inner tube to move vertically only along the axis of the sleeve, ensuring the linear accuracy of the up and down movement of the molding mechanism and avoiding deviation affecting the foam molding quality.

[0019] As a further improvement of the present technical solution, the demolding mechanism includes a first rack fixedly connected to both sides of the inner cylinder, a gear meshed at the outer edge of the first rack, a second rack meshed at the outer edge of the gear, a moving rod fixedly connected to one side of the second rack, and a piston fixedly connected to the bottom of the moving rod, the first rack is adapted to the sliding grooves on both sides of the sleeve, connecting plates are fixedly connected on both sides of the gear, and the bottom surface of the connecting plate is fixedly connected to the top surface of the bracket, the outer wall of the moving rod is slidably connected to a stabilizing frame, one end of the stabilizing frame is connected to the bracket, the first rack and the second rack are respectively located on both sides of the gear, and a groove for sliding the first rack is provided on the bracket.

[0020] The beneficial effect of adopting the above-mentioned further scheme is that when the piston moves up and down with the moving rod, an air squeezing and suction effect is formed inside the molding mold, forcing the air circulation to take away the heat generated during the molding process (such as heat generated by friction under pressure of the foam, heat generated by the hydraulic system, etc.), avoiding overheating of the mold causing carbonization or deformation of the foam, and improving the molding quality and mold life.

[0021] The second object of the present invention is to provide a composite buffer foam for a new energy power battery module. The compression molding process of the composite buffer foam for a new energy power battery module used in any one of the above-mentioned items includes a composite buffer foam, and the composite buffer foam includes a first folding part, a second folding part, and a third folding part. The composite buffer foam is compression molded by a molding mold. The composite buffer foam realizes the folding of the composite buffer foam by setting the first folding part, the second folding part, and the third folding part. The foldable buffer foam can be deformed by folding and fits tightly to the irregular contour of the battery module. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] like Figure 1-7As shown, one of the purposes of the present invention is to provide a composite buffer foam molding process for new energy power battery modules, including

[0037] The first step is to place the pre-prepared composite cushioning foam 100 on the conveyor 200;

[0038] In the second step, the hydraulically driven molding mechanism 300 starts to operate, applying pressure to the composite cushioning foam 100 on the conveyor 200, molding it into a specific foldable shape;

[0039] Step 3: After the composite cushioning foam 100 is molded, the demoulding mechanism 400 intervenes to smoothly remove the molded foam from the mold.

[0040] The molding mechanism 300 is hydraulically driven to precisely mold the composite cushioning foam 100 into a specific foldable structure. During the linear displacement of the molding mechanism 300, the elastic linkage structure built into the molding mechanism 300 synchronously drives the demolding mechanism 400 to move in the opposite direction to achieve efficient demolding. In addition, when the demolding mechanism 400 ejects the molded composite cushioning foam 100, the airflow generated by the movement causes the air inside the molding mechanism 300 to form a forced convection circulation to achieve cooling.

[0041] Therefore, based on the above features, the improvements of the present invention are described in detail:

[0042] In the process of molding the composite cushioning foam 100 using the molding structure, the cut portion of the composite cushioning foam 100 is very likely to adhere to the bottom of the molding structure, making it impossible to demold smoothly. Therefore, manual operation or other demolding tools are required to complete the demolding of the composite cushioning foam 100. If the force is not properly controlled during the manual operation, it may cause damage and deformation to the foam surface, affecting the appearance quality and performance of the product, and thus resulting in a decrease in the product qualification rate. Therefore, the molding mechanism 300 is driven by hydraulic means to mold the composite cushioning foam 100 into a specific shape. During the movement of the mold pressing mechanism 00, its built-in elastic linkage structure will synchronously drive the demoulding mechanism 400 to move in the opposite direction, and the demoulding mechanism 400 will gradually eject the composite cushioning foam 100 during the movement. On the one hand, the automated demoulding process reduces the need for manual operation, speeds up production, and improves overall production efficiency. Demolding is performed immediately after the molding is completed, and the next round of production cycle can be quickly prepared. On the other hand, the use of the demoulding mechanism 400 to eject the composite cushioning foam 100 in a controlled manner can more accurately control the force and direction compared to manual demoulding, reducing the risk of product damage or deformation caused by human factors.

[0043] Because when the composite cushioning foam 100 is compression-molded, the mold needs to be heated to meet the molding temperature requirements of the foam material, but the molding part of the mold is often subjected to high temperature and high pressure for a long time, and the heat accumulation is difficult to dissipate quickly, which is prone to overheating. Overheating will not only cause local degradation of the foam material, resulting in yellowing and decreased elasticity, but also make the foam material more likely to adhere to the mold, causing demolding difficulties and increasing product tearing. Therefore, in the process of ejecting the molded composite foam through the demolding mechanism 400, the airflow generated by the movement of the demolding mechanism 400 can prompt the air inside the molding mechanism 300 to form a forced convection circulation, thereby achieving cooling of the molding mechanism 300. On the one hand, the forced convection circulation takes away excess heat from the molding mechanism 300, avoiding the problem of local overheating of the mold leading to degradation of the foam material, yellowing and decreased elasticity, thereby ensuring the foam cushioning performance and dimensional accuracy; on the other hand, accelerated air circulation can achieve a cooling effect, making it less likely for the foam to adhere to the mold, thereby facilitating demolding.

[0044] On the basis of the above, the specific structure is disclosed in detail:

[0045] Considering that the molding mechanism 300 is required to mold the composite cushioning foam 100, Figure 1 and Figure 2 As shown, both sides of the conveyor 200 are fixedly connected with a fixed plate for installing the conveyor 200, and one side of the fixed plate is fixedly connected with a hydraulic lifting rod 201. The conveyor 200 adopts a roller crawler conveyor. The interior of the conveyor 200 is formed by a plurality of rollers arranged. The crawler is engaged with the outer walls of the rollers at both ends for transmission (the motor output shaft is connected to the roller end as the driving source), and the inner wall of the crawler is synchronously attached to the outer walls of the multiple rollers for transmission, so that the densely arranged rollers form a rigid support surface. When the molding mechanism 300 is pressed down, the pressure acts on the crawler, that is, on the rigidly supported roller, and the overall rigid structure is used to disperse the load, avoid deformation of the conveyor, and ensure that the molding process is stable and reliable.

[0046] The molding mechanism 300 includes a molding mold 310 fixedly connected to the bottom of one end of the hydraulic lifting rod 201. Through holes are opened on both sides of the molding mold 310 for moving the demolding mechanism 400. A lower pressure plate 311 is fixedly connected to the inside of the molding mold 310. The height of the lower pressure plate 311 is lower than the height of the two sides of the molding mold 310. The height of the lower pressure plate 311 is lower than the height of the two sides of the molding mold 310, so that when molding the composite cushioning foam 100, the two sides of the molding mold 310 can completely break the two sides of the foam, while the middle part of the foam will not be completely broken, thereby facilitating the folding of the molded composite cushioning foam 100.

[0047] Furthermore, to realize the lifting and lowering of the molding mechanism 300, the molding mechanism 300 is disclosed in detail, such as Figure 3-Figure 6As shown, the top of one end of the hydraulic lifting rod 201 is fixedly connected to the inner cylinder 320, the outer wall of one end of the inner cylinder 320 is fixedly connected to a protruding block 321, and a buffer spring is sleeved on the inner cylinder 320, and the top of the buffer spring is fixedly connected to a sleeve 322. Slide grooves 323 are provided on both sides of the sleeve 322, and a bracket 324 is fixedly connected to the sleeve 322. The bottom end of the bracket 324 is connected to the fixed plate. Therefore, when it is necessary to mold the composite buffer foam 100, the hydraulic lifting rod 201 is started, and the hydraulic lifting rod 201 descends, driving the molding mold 310 and the inner cylinder 320 to descend synchronously. As the inner cylinder 320 moves downward in the sleeve 322, the protruding block 321 will be driven to move downward together. During this process, the protruding block 321 will stretch the buffer spring. When the molding mold 310 is pressed down to a specific position, the molding of the composite buffer foam 100 can be completed. The sliding fit of the inner cylinder 320 in the sleeve 322, combined with the linkage between the protruding block 321 and the buffer spring, makes the entire molding structure more stable during operation, reduces shaking or offset during the pressing process, and ensures the accuracy of molding. It is suitable for the production of composite buffer foam 100 for new energy power batteries with high dimensional accuracy requirements.

[0048] However, to realize the demoulding of the composite cushioning foam 100, the demoulding mechanism 400 is disclosed in detail, such as Figure 4-Figure 6 As shown, the demoulding mechanism 400 includes a first rack 410 fixedly connected to both sides of the inner cylinder 320, a gear 411 is meshedly connected to the outer edge of the first rack 410, and a second rack 412 is meshedly connected to the outer edge of the gear 411. A moving rod 413 is fixedly connected to one side of the second rack 412, and a piston 414 is fixedly connected to the bottom of the moving rod 413. Therefore, after the composite cushioning foam 100 is molded, the hydraulic lifting rod 201 is started to drive the molding mold 310 and the inner cylinder 320 to rise. When the inner cylinder 320 rises, the first rack 410 is driven to rise synchronously. The movement of the first rack 410 drives the gear 411 to rotate, thereby driving the second rack 412 to move downward. During the descent of the second rack 412, the moving rod 413 and the piston 414 are driven to move downward synchronously in the molding mold 310, ejecting the composite cushioning foam 100 and accelerating the air flow inside the molding mold 310. On the one hand, the piston 414 ejects the foam smoothly. Compared with the traditional rough demoulding method, it can reduce the problems of foam tearing and deformation caused by uneven external force, thereby improving the product qualification rate and ensuring the cushioning performance and appearance quality of the foam; on the other hand, when the piston 414 descends in the mold, it promotes the rapid flow of internal air, accelerates the heat dissipation of the mold, avoids local overheating of the mold and causes subsequent foam molding defects, and reduces the risk of adhesion between the foam and the mold, facilitating the next molding operation.

[0049] Specifically, the first rack 410 is adapted to the slide grooves 323 on both sides of the sleeve 322, and connecting plates are fixedly connected on both sides of the gear 411, and the bottom surface of the connecting plate is fixedly connected to the top surface of the bracket 324. The outer wall of the movable rod 413 is slidably connected to the stabilizing frame 415, and one end of the stabilizing frame 415 is connected to the bracket 324. The first rack 410 and the second rack 412 are respectively located on both sides of the gear 411, and a groove for sliding the first rack 410 is provided on the bracket 324 to ensure that the first rack 410 can only move linearly along the vertical direction (such as the vertical direction) of the slide groove 323, thereby avoiding misalignment of the rack and gear 411 due to shaking, and ensuring the stability of power transmission.

[0050] The second purpose of the present invention is to provide a composite buffer foam 100 for a new energy power battery module, which is applied to the compression molding process of the composite buffer foam 100 for a new energy power battery module of any one of the above-mentioned items, including a composite buffer foam 100, the composite buffer foam 100 including a first folding part 101, a second folding part 102 and a third folding part 103, and the composite buffer foam 100 is compression molded by a molding mold 310. The composite buffer foam 100 realizes the folding of the composite buffer foam 100 through the arrangement of the first folding part 101, the second folding part 102 and the third folding part 103. The foldable buffer foam can be deformed by folding and fits tightly to the irregular contour of the battery module (such as the concave and convex gaps between battery cells, the special-shaped structure of the module edge, etc.), filling the space that is difficult to cover with traditional hard buffer materials.

[0051] Working principle of the present invention:

[0052] First, the pre-prepared composite cushioning foam 100 is placed on the conveyor 200. The fixed plates on both sides of the conveyor 200 are connected to the hydraulic lifting rods 201 to prepare for the subsequent process. Then, the hydraulic lifting rods 201 are started to drive the molding mechanism 300 to descend, and the forming mold 310 applies pressure to the foam on the conveyor 200. Since the height of the lower pressure plate 311 in the forming mold 310 is lower than the two sides of the mold, the two sides of the foam are crushed and the middle part is retained, thereby being molded into a specific foldable shape. After the foam is molded, the hydraulic lifting rods 201 drive the molding mechanism 300 to rise. During this process, the inner cylinder 320 rises through the transmission of the first rack 410, the gear 411, and the second rack 412, driving the moving rod 413 and the piston 414 to descend, and ejecting the molded foam; at the same time, the airflow generated by the movement of the piston 414 promotes forced convection circulation of the air inside the molding mechanism 300, thereby cooling the mold for the next molding, and completing continuous production in this cycle.
