In the hot-pressing state, the opening and closing mechanism drives the two receiving rods to move away from each other in the horizontal direction, and at the same time, the lifting mechanism drives the two sets of receiving rods to descend and move to both sides of the lower pressing die respectively, so as to release the supporting force applied by the receiving rods on the flexible pad and avoid the hot-pressing operation of the hot-pressing module on the product to be hot-pressed.

[0040] In the prior art, the lower pressing die of a hot press usually adopts a three-part split structure, and the movable part is used to transfer materials. The gap of this split lower pressing die causes indentations on the surface of the battery cell during the hot pressing process of the battery cell, affecting the quality of the battery cell.

[0041] The present utility model proposes a loading and transfer structure.

[0042] Please refer to Figures 1 to 2 As shown, in an embodiment of the present utility model, the loading and transfer structure is applied to the loading of a hot pressing module. The hot pressing module includes a lower pressing die 600, and the lower pressing die 600 is of an integral structure. The loading and transfer structure includes: a flexible pad assembly and a lifting assembly. Among them, the flexible pad assembly includes a flexible pad 100 and a tensioning mechanism, and the lifting assembly is located below the flexible pad and includes a lifting mechanism, an opening and closing mechanism 400, and two receiving rods 300.

[0043] It should be noted that the flexible pad 100 is located above the lower pressing die 600. In the specific implementation process, the lifting mechanism includes two lifting frames 200, and the two lifting frames 200 are respectively located at both ends of the receiving rod 300. Correspondingly, a set of opening and closing mechanisms 400 and a lifting driving member 210 are provided on each lifting frame 200 to ensure the balance and stability of the movement of the receiving rod 300.

[0044] Two sets of receiving rods 300 are slidably connected to the lifting frame 200, and the two sets of receiving rods 300 are arranged side by side along the sliding direction. The opening and closing mechanism 400 is arranged on the lifting frame 200, and the opening and closing mechanism 400 is drivingly connected to the two sets of receiving rods 300 and drives the two sets of receiving rods 300 to move towards or away from each other in the horizontal direction. The receiving rods 300 are located below the flexible pad 100. The lifting driving member 210 is connected to the lifting frame 200 and drives the lifting frame 200 to lift and lower, so that the receiving rods 300 have a material receiving position and an avoidance position. At the material receiving position, the two sets of receiving rods 300 move towards each other and lift up the flexible pad 100, so that a downward slope is formed on both sides of the receiving rods 300 and the flexible pad 100 to avoid the feeding mechanism of the product to be hot-pressed. At the avoidance position, the two sets of receiving rods 300 move away from each other and are respectively located on both sides of the lower pressing die 600.

[0045] In the specific implementation process, the two sets of receiving rods 300 are parallel to each other. The two ends of the receiving rod 300 are respectively connected to the opening and closing mechanism 400, and the opening and closing mechanism 400 drives the receiving rod 300 to slide along the lifting frame 200 to approach or move away from each other. In this embodiment, the lifting driving member 210 adopts a lifting cylinder, and the output end of the lifting cylinder is connected to the lifting frame 200 and drives the lifting frame 200 to rise and fall. In order to improve the stability of the lifting frame 200, in the specific implementation process, linear bearings and support columns are also connected to both ends of the lifting frame 200, and the lifting frame 200 slides up and down along the support column through the linear bearings.

[0046] When it is necessary to receive the hot-pressed battery core, that is, when the flexible pad assembly is in the material receiving state, specifically, the lifting cylinder drives the lifting frame 200 to lift, and the receiving rod 300 located below the flexible pad 100 is lifted synchronously. At the same time, the opening and closing mechanism 400 drives the two sets of receiving rods 300 to move towards each other in the horizontal direction and approach. The receiving rod 300 rises to lift the middle part of the flexible pad 100, so that the middle part of the flexible pad 100 close to the middle position bulges upward and forms a downward slope with the two side edges of the flexible pad 100, so as to avoid the battery core gripper during the battery core feeding, and then the feeding mechanism can smoothly place the battery core on the flexible pad 100 and is also supported by the receiving rod 300. It can be understood that the battery core gripper is used for the battery core feeding of the hot-pressing module.

[0047] After the hot pressing module is loaded, the battery cell is located on the flexible pad 100. When hot pressing is required, that is, when the flexible pad assembly is in the hot pressing state, the receiving rod 300 presses downward and the lower die 600 descends. Specifically, the lifting cylinder drives the lifting frame 200 to descend, and the receiving rod 300 descends synchronously. During the descent, the opening and closing mechanism 400 drives the two receiving rods 300 to move away from each other in the horizontal direction. The opening and closing mechanism 400 drives the two receiving rods 300 to descend to remove the supporting force applied to the flexible pad 100, and the two receiving rods 300 slide to both sides of the lower die 600 to ensure that the lower die 600 can smoothly perform the hot pressing operation. At this time, the battery cell is located on the flexible pad 100.

[0048] The technical solution of the present utility model uses two receiving rods 300 and the flexible pad 100 to receive the product to be hot pressed, and drives the lifting frame to rise and fall through the lifting driving member 210 so that the receiving rod 300 switches between the material receiving state and the hot pressing state. Further, the opening and closing mechanism 400 also drives the two receiving rods 300 to move towards each other or away from each other. Specifically, in the material receiving state, the opening and closing mechanism 400 drives the two receiving rods 300 to move towards each other in the horizontal direction, and at the same time the lifting mechanism drives the two receiving rods 300 to lift and support the middle part of the flexible pad 100, so that both sides of the middle part of the flexible pad 100 are inclined downward to avoid the battery cell gripper, and the product to be hot pressed is placed on the flexible pad 100 and the receiving rod 300. In the hot pressing state, the opening and closing mechanism 400 drives the two receiving rods 300 to move away from each other in the horizontal direction. At the same time, the lifting mechanism drives the two receiving rods 300 to descend and move to both sides of the lower die 600 respectively, so as to release the supporting force applied by the receiving rod 300 on the flexible pad 100 and avoid the hot pressing operation of the hot pressing module on the product to be hot pressed. In this way, the lower die 600 of the hot pressing module does not need to transfer materials and adopts an integrated structure, thereby avoiding the appearance of indentations on the surface of the battery cell and improving the quality of the battery cell.

[0049] Reference Figures 3 to 4 As shown, in an embodiment, the opening and closing mechanism 400 includes a transmission belt 420 and two transmission wheels 430; the two transmission wheels 430 are connected to the lifting mechanism, and the transmission belt 420 is sleeved between the two transmission wheels 430; the two receiving rods 300 are respectively connected to the first belt body and the second belt body of the transmission belt 420 through connecting plates 440, and the transmission directions of the first belt body and the second belt body are opposite.

[0050] In the specific implementation process, in order to improve the accuracy and stability of the movement of the receiving rod 300, the driving wheel 430 is a synchronous wheel. Correspondingly, the transmission belt 420 is a synchronous belt. It can be understood that the part of the synchronous belt between the two synchronous wheels forms a first belt body and a second belt body. One connecting plate 440 is connected to the first belt body, and the other connecting plate 440 is connected to the second belt body. In this way, when the synchronous belt rotates, the movement directions of the two connecting plates 440 are opposite. The connecting plate 440 is connected with a clamping plate, the clamping plate is provided with a toothed structure and is clamped with the synchronous belt, and the connecting plate 440 and the clamping plate are clamped and fixedly connected to the synchronous belt.

[0051] Furthermore, the opening and closing mechanism further includes a driving cylinder 410. The driving cylinder 410 is connected to the lifting mechanism and is connected to one of the connecting plates 440.

[0052] In the specific implementation process, the driving cylinder 410 is fixedly connected to the lifting frame 200. The two driving wheels 430 are respectively rotatably connected to the lifting frame 200. The transmission belt 420 is connected to the driving wheels 430. The two groups of receiving rods 300 are respectively correspondingly connected with connecting plates 440. The two connecting plates 440 are respectively connected to the transmission belt 420. The driving cylinder 410 is connected to one of the two connecting plates 440 and drives the connecting plate 440 to move horizontally. The transmission belt 420 is connected to the two connecting plates 440 so that the receiving rod 300 moves. The driving cylinder 410 is fixedly connected to one side of the lifting frame 200. The output end of the driving cylinder 410 is connected to one of the connecting plates 440 and pushes the connecting plate 440 to move horizontally, thereby causing the synchronous belt to rotate, and the other connecting plate 440 moves in the opposite direction. The two connecting plates 440 are also respectively correspondingly connected to two groups of receiving rods 300, thereby realizing the opposite or separating movement of the two groups of receiving rods 300.

[0053] Furthermore, the lifting frame 200 is connected with a tensioning block 450. One of the two driving wheels 430 is connected to the tensioning block 450. The lifting frame 200 is provided with a long strip-shaped adjusting hole. The tensioning block 450 is connected to the lifting frame 200 and is connected at the adjusting hole. By adjusting the position of the tensioning block 450 on the lifting frame 200, the distance between the two driving wheels 430 is adjusted, thereby realizing the tensioning of the transmission belt 420.

[0054] In one embodiment, a slide rail is provided on the lifting mechanism, and the receiving rod is connected to the slider 230 of the slide rail 220. In this embodiment, the loading and unloading transfer structure further includes a sliding assembly, which includes a slide rail 220 and a slider 230. The slide rail 220 is provided on the lifting frame 200, and the two receiving rods 300 are respectively connected to the slider 230 correspondingly, and the slider 230 slides along the slide rail 220. Specifically, the slide rail 220 is installed at the top of the lifting frame 200, the two sliders 230 slide along the slide rail 220, the end of the receiving rod 300 is connected to the slider 230, the two sliders 230 are respectively connected to the two receiving rods 300 correspondingly, and the slider 230 is also fixedly connected to the connecting plate 440. In this way, the receiving rod 300 slides along the lifting frame 200 through the sliding assembly.

[0055] In one embodiment, the loading and unloading transfer structure further includes an induction assembly, which includes a triggering member and a first sensor 240 and a second sensor 250 that are arranged in cooperation with the triggering member. The first sensor 240 and the second sensor 250 are arranged at intervals in the vertical direction. The triggering member is provided on the lifting frame 200 of the lifting mechanism. When the triggering member triggers the first sensor 240, the lifting mechanism stops the lifting action. When the triggering member triggers the second sensor 250, the lifting mechanism stops the descending action.

[0056] In the specific implementation process, when the jacking driving member 210 drives the lifting frame 200 to rise, the triggering member triggers the first sensor 240, the jacking driving stops, and the receiving rod 300 reaches the loading position to load the battery cell; when the jacking driving member 210 drives the lifting frame 200 to descend, the triggering member triggers the second sensor 250, the jacking driving member 210 stops, and the receiving rod 300 reaches the avoidance position, and the hot pressing module performs the hot pressing work on the battery cell.

[0057] In one embodiment, a rotating roller 310 is sleeved on the receiving rod 300, and the rotating roller 310 is rotationally and coaxially matched with the receiving rod 300. The rotating roller 310 contacts the flexible pad 100, and a rolling friction is formed between the rotating roller 310 and the flexible pad, reducing the frictional resistance and making the sliding of the bearing rod smoother.

[0058] In one embodiment, refer to Figure 5 As shown, the loading and unloading transfer structure further includes a tensioning mechanism 500, which includes: two mounting seats 570, two groups of fixing components 520, and a resetting member 530. Among them, both sides of the flexible pad 100 are fixedly connected to the two groups of fixing components 520 respectively. The mounting seat is provided with a mounting shaft 510. The two ends of the fixing component 520 are respectively slidably connected to the mounting seat 570 through the mounting shaft. The receiving rod 300 lifts the flexible pad 100 and drives the two groups of fixing components 520 to move towards each other along the mounting shaft 510; the resetting member 530 is clamped between the mounting seat 570 and the fixing component 520, and the resetting member 530 is compressed and stores energy / releases the compressed energy when the fixing component 520 slides relative to the mounting seat 570.

[0059] In this embodiment, the extension direction of the mounting shaft 510 is consistent with the sliding direction of the receiving rod 300 on the lifting frame 200. In a specific implementation, the reset member 530 is a compression spring that is sleeved onto the mounting shaft 510, and the end of the compression spring is connected to the fixing assembly 520. It can be understood that when the receiving rod 300 supports the flexible pad 100, the flexible pad 100 located on both sides of the receiving rod 300 will move closer to each other, driving the two sets of fixing assemblies 520 to slide toward each other along the mounting shaft 510. During the descent of the receiving rod 300, the compression spring drives the two sets of fixing assemblies 520 to slide away from each other, causing the two sides of the flexible pad 100 to reset. The flexible pad 100 is located above the lower die 600, and the fixing assembly 520 is used to fix the flexible pad 100 so that when the receiving rod 300 is in the avoidance position, the flexible pad 100 can receive the battery cell.

[0060] The fixing assembly 520 includes a base plate 521, a pressure plate 522 and a locking member 523. The locking member 523 is respectively connected to the base plate 521 and the pressure plate 522. The end of the base plate 521 is connected to a guide block 540. The guide block 540 is slidingly connected to the mounting shaft 510. The flexible pad 100 is arranged between the base plate 521 and the pressure plate 522 and is locked by the locking member 523.

[0061] In practice, the flexible pad 100 is made of Teflon, which provides a certain degree of strength. The two ends of the base plate 521 are connected to corresponding guide blocks 540, which slide along the mounting shaft 510. A pressure plate 522 is connected above the base plate 521. The flexible pad 100 is positioned between the base plate 521 and the pressure plate 522. The flexible pad 100 is clamped between the base plate 521 and the pressure plate 522 using locking members 523, such as screws. Specifically, the screws can be square-wing butterfly screws, which can be removed and installed without special tools, facilitating disassembly and installation.

[0062] In one embodiment, the mounting shaft 510 is provided with two fixing rings 550. A reset member 530 is connected to each of the two fixing rings 550 on opposite sides thereof. The reset member 530 is connected to a guide block 540 on one end thereof facing away from the fixing ring 550. Specifically, the fixing ring 550 is fixedly sleeved on the mounting shaft 510. Adjusting the position of the fixing ring 550 can adjust the degree of tension on the flexible pad 100. The reset member 530 is located between the fixing ring 550 and the guide block 540. In a specific implementation, the guide block 540 is positioned near the end of the mounting shaft 510. When the two sets of fixing assemblies 520 approach each other, the two reset members 530 are compressed by the two guide blocks 540. Under the action of elastic force, the two reset members 530 drive the two guide blocks 540 to slide away from each other along the mounting shaft 510, thereby resetting the two sets of fixing assemblies 520.

[0063] In one embodiment, the tensioning mechanism 500 further includes a guide shaft 560. The mounting shaft 510 and the guide shaft 560 are arranged in parallel and are both disposed on the mounting base 570. The guide block 540 is also slidably connected to the guide shaft 560. Further, baffles 580 are connected to the ends of the guide shaft 560 and / or the mounting shaft 510.

[0064] Specifically, the mounting base 570 is located at the middle position of the mounting shaft 510 and is located between the two fixing rings 550. The guide shaft 560 is arranged in parallel with the mounting shaft 510 to balance and guide the movement of the guide block 540. In addition, the baffles 580 are respectively connected to the two ends of the guide shaft 560 or the mounting shaft 510, or the baffles 580 are connected to the ends of both the guide shaft 560 and the mounting shaft 510 to prevent the guide block 540 from falling off the mounting shaft 510 and the guide shaft 560. In another embodiment, the mounting base 570 is connected to a connecting plate 440. The first sensor 240 and the second sensor 250 are fixedly mounted on the connecting plate 440. It should be noted that the tensioning mechanism 500 includes two sets of mounting shafts 510. The two sets of mounting shafts 510 are respectively located at both ends of the fixing component 520, and a reset member 530 is provided on each mounting shaft 510. In addition, guide shafts 560 and mounting bases 570 are provided at both ends of the bottom plate 521 to ensure the balance and stability of the movement of the fixing component 520.
