[0001] This utility model relates to the field of battery manufacturing technology, specifically to an integrated device for pre-installation and pressing of lithium battery cap sealing rings. Background Technology
[0002] With the rapid development of the new energy industry, the need for optimizing the manufacturing process of lithium batteries, as core energy storage devices, is becoming increasingly urgent. The pre-installation and pressing of the lithium battery cap sealing ring is a key step in battery packaging. To meet the demands of high consistency and high efficiency in large-scale production, the industry urgently needs to develop integrated and automated equipment.
[0003] When pre-installing and pressing the sealing ring of the lithium battery cap, the material is usually conveyed by vibration. This feeding method is prone to multiple materials running in parallel, which can lead to errors during processing. On the other hand, after pressing the cap and sealing ring together, there are still small gaps between the cap and the sealing ring, which affects the processing quality of the cap. Utility Model Content
[0004] The technical problem to be solved by this utility model is: to provide an integrated device for pre-installation and pressing of lithium battery cap sealing ring. Through the sorting component, the sealing ring can be evenly spread out, and the material guide groove can solve the problem of multiple materials running in parallel. Through the preheating component, after the cap and sealing ring are pressed together, the sealing ring will actively tighten towards the cap, thereby improving the sealing performance between the cap and the sealing ring.
[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:
[0006] An integrated device for pre-assembling and pressing lithium battery cap sealing rings includes: a workbench with a cap feeding box and a sealing ring feeding cylinder mounted on top of the workbench; a pressing block frame connected to one side of the workbench; multiple support rods connected to the bottom of the sealing ring feeding cylinder; a sorting component mounted on top of the workbench for sorting and automatically feeding materials; the sorting component includes a cap feeding trough, a turntable, and a guide box; and a preheating component mounted on one side of the sealing ring feeding cylinder for preheating the materials to improve the pressing effect; the preheating component includes a heating jacket, an electric heating tube, and a pressing block.
[0007] Preferably, the cap feeding box has a cap feeding groove inside, the workbench is equipped with an electric push rod on top, the cap feeding box has a movable groove inside, one end of the electric push rod extends into the movable groove and is connected to a push plate, the workbench is connected to a fixed column, the fixed column is equipped with a motor, the top of the motor is connected to a rotating rod, the sealing ring feeding cylinder has a turntable inside, one end of the rotating rod is rotatably connected to the bottom of the turntable, the sealing ring feeding cylinder is equipped with a guide box, the guide box has a guide groove on one side, the guide box has a discharge port on one side, the workbench is equipped with a pressing groove, the sealing ring feeding cylinder has a feeding port corresponding to the discharge port inside, and a sealing ring feeding pipe is connected to one side of the feeding port.
[0008] Preferably, the sealing ring feeding pipe has a sealing ring feeding groove inside, one end of the sealing ring feeding pipe is connected to a heating sleeve, the heating sleeve has multiple electric heating tubes inside, the heating sleeve has a heating groove inside, the outlet of the heating groove is located at the top of the pressing groove, a hydraulic rod is installed on the top of the pressing block frame, and one end of the hydraulic rod is connected to a pressing block.
[0009] The beneficial effects of this utility model are:
[0010] The advantage of this invention is that by utilizing the cap feeding trough, turntable, and guide box in the sorting assembly, the turntable is driven to rotate by a motor. During the rotation of the turntable, the sealing ring is affected by centrifugal force and spreads outward. Then, it enters the sealing ring feeding tube through the guide trough, thus avoiding the risk of multiple materials running in parallel.
[0011] Secondly, through the heating jacket, heating tube and flattening block in the preheating assembly, the heating tube inside the heating jacket heats the sealing ring, causing the sealing ring to temporarily expand due to heat and increase its area.

[0017] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0018] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0019] like Figures 1-4 As shown, the lithium battery cap sealing ring pre-installation and pressing integrated device includes a worktable 1, a cap feeding box 101 installed on the top of the worktable 1, a sealing ring feeding cylinder 102 installed on the top of the worktable 1, a pressing frame 103 connected to one side of the worktable 1, and multiple support rods 104 connected to the bottom of the sealing ring feeding cylinder 102. A sorting component set on the top of the worktable 1 is used to sort the materials and automatically feed them. The sorting component includes: a cap feeding trough 2, a turntable 303, and a guide box 4. A preheating component set on one side of the sealing ring feeding cylinder 102 is used to preheat the materials to improve the pressing effect of the materials. The preheating component includes: a heating jacket 601, an electric heating tube 603, and a pressing block 701.
[0020] In this process, the cap feeding trough 2, turntable 303, and guide box 4 in the sorting component are used. The turntable 303 is driven to rotate by the motor 301. During the rotation of the turntable 303, the sealing ring is affected by centrifugal force and spreads outward. Then, it enters the sealing ring feeding tube through the guide trough 401, avoiding the risk of multiple materials running in parallel. Secondly, the heating jacket 601, electric heating tube 603, and flattening block 70 in the preheating component are used. The electric heating tube 603 inside the heating jacket 601 heats the sealing ring, causing the sealing ring to temporarily expand due to heat and increase its area. Subsequently, the temperature drops after pressing, and the sealing ring shrinks and fills the micro gaps in the cap, improving the pressing quality of the cap and the sealing ring.
[0021] The cap feeding box 101 has a cap feeding slot 2 inside, the workbench 1 has an electric push rod 201 on top, the cap feeding box 101 has a movable slot 203 inside, one end of the electric push rod 201 extends into the movable slot 203 and is connected to a push plate 202. The workbench 1 has a fixed column 3 on top, a motor 301 installed inside the fixed column 3, and a rotating rod 302 connected to the top of the motor 301. The sealing ring feeding cylinder 102 has a... The device is equipped with a turntable 303, and one end of a rotating rod 302 is rotatably connected to the bottom of the turntable 303. The device is characterized in that a guide box 4 is installed inside the sealing ring feeding cylinder 102, a guide groove 401 is opened on one side of the guide box 4, a discharge port 403 is opened on one side of the guide box 4, and a pressing groove 402 is opened on the top of the workbench 1. The device is characterized in that a feeding port 5 corresponding to the discharge port 403 is opened inside the sealing ring feeding cylinder 102, and a sealing ring feeding pipe 501 is connected to one side of the feeding port 5.
[0022] When pre-installation of the cap and sealing ring is required, the sealing ring is first placed on the sealing ring feed cylinder 102. Then, the motor 301 drives the rotating rod 302 to rotate the turntable 303. Centrifugal force is used to evenly distribute the sealing ring to the outer edge of the turntable 303. When the sealing ring is rotated to the position of the guide box 4, the sealing ring is arranged in an orderly manner through the single limiting structure of the guide groove 401. Then the sealing ring enters the inside of the guide box 4, then enters the feed port 5 through the discharge port 403, and then enters the inside of the sealing ring feed tube 501. Since the space of the guide groove 401 can only allow a single material to pass through, the screening of the guide groove 401 ensures that only a single sealing ring enters the feed port 5 at a time, effectively solving the problem of multiple materials passing through simultaneously.
[0023] The sealing ring feeding pipe 501 has a sealing ring feeding groove 6 inside, and a heating sleeve 601 is connected to one end of the sealing ring feeding pipe 501. Multiple electric heating tubes 603 are installed inside the heating sleeve 601, and a heating groove 602 is opened inside the heating sleeve 601. The outlet of the heating groove 602 is located at the top of the pressing groove 402. The feature is that a hydraulic rod 7 is installed on the top of the pressing block frame 103, and a pressing block 701 is connected to one end of the hydraulic rod 7.
[0024] Because small gaps may remain between the cap and the sealing ring after pressing, the cap may experience insufficient sealing during subsequent use. After the sealing ring enters the heating jacket 601 through the sealing ring feeding pipe 501, the heating element 603 heats the sealing ring inside the heating tank 602. The sealing ring temporarily expands upon heating and then falls into the pressing tank 402. To prevent the sealing ring from tilting due to its falling inertia, the hydraulic rod 7 drives the flattening block 701 to gently press the sealing ring, ensuring the bottom of the sealing ring is fully flattened. When the sealing ring reaches the inside of the pressing groove 402, it is in contact with the surface of the pressing groove 402. When the sealing ring reaches the inside of the pressing groove 402, the electric push rod 201 in the cap feeding box 101 pushes the push plate 202 to push the cap from the inside of the cap feeding groove 2 into the inside of the pressing groove 402. Then, the hydraulic rod 7 drives the pressing block 701 to press the cap and the sealing ring together. Since the sealing ring is temporarily in an expanded state, the cap can be pressed more easily with the sealing ring. After the pressing is completed, the sealing ring is in the cooling stage, which causes the sealing ring to actively tighten towards the cap, improving the sealing performance between the cap and the sealing ring.
[0025] Working principle:
[0026] When pre-installation of the cap and sealing ring is required, the sealing ring is first placed on the sealing ring feed cylinder 102. Then, the motor 301 drives the rotating rod 302 to rotate the turntable 303. Centrifugal force is used to evenly distribute the sealing ring to the outer edge of the turntable 303. When the sealing ring is rotated to the position of the guide box 4, the sealing ring is arranged in an orderly manner through the single limiting structure of the guide groove 401. Then the sealing ring enters the inside of the guide box 4, then enters the feed port 5 through the discharge port 403, and then enters the inside of the sealing ring feed tube 501. Since the space of the guide groove 401 can only allow a single material to pass through, the screening of the guide groove 401 ensures that only a single sealing ring enters the feed port 5 at a time, effectively solving the problem of multiple materials passing through simultaneously.
[0027] After the sealing ring enters the heating jacket 601 through the sealing ring feeding pipe 501, the electric heating tube 603 heats the sealing ring inside the heating tank 602. The sealing ring is temporarily in an expanded state after being heated, and then falls into the pressing tank 402. In order to prevent the sealing ring from being in a tilted state due to the inertia of falling, the hydraulic rod 7 drives the pressing block 701 to press the sealing ring slightly, so that the bottom of the sealing ring is completely in contact with the surface of the pressing tank 402. When the sealing ring reaches the inside of the pressing tank 402, the electric push rod 201 in the cap feeding box 101 pushes the push plate 202 to push the cap from the inside of the cap feeding groove 2 into the inside of the pressing tank 402. Then, the hydraulic rod 7 drives the pressing block 701 to press the cap and the sealing ring together. Since the sealing ring is temporarily in an expanded state, the cap can be pressed more easily with the sealing ring. After the pressing is completed, the sealing ring is in a cooling stage, which causes the sealing ring to actively tighten towards the cap, improving the sealing performance between the cap and the sealing ring.
