Abstract
Description
Technical Field
[0001] This utility model relates to the field of pouch battery processing technology, and in particular to a tab cutting device for pouch batteries. Background Technology
[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes to generate an electric current. It is a cup, tank, or other container or a portion of a composite container. It has positive and negative electrodes. With technological advancements, the term "battery" now generally refers to a small device that generates electrical energy. When using a battery, the tabs need to be cut and processed. This requires tab cutting equipment for pouch batteries. Tabs are a raw material for lithium-ion polymer batteries; for example, they are used in mobile phone batteries, Bluetooth batteries, and laptop batteries.
[0003] To this end, patent publication CN222113650U discloses an electrode tab cutting device, relating to the field of electrode tab cutting technology. The electrode tab cutting device includes a support; a lower cutting blade holder fixed to the support, with a guide post fixed to the lower cutting blade holder; a lower cutting blade fixed to the lower cutting blade holder; a first driving unit disposed on the support; an upper cutting blade holder fixed to the moving end of the first driving unit, the first driving unit driving the upper cutting blade holder to reciprocate along the guide post; an upper cutting blade fixed to the upper cutting blade holder; and a blade-stopping mechanism including a pusher portion disposed on the back side of the upper cutting blade, the pusher portion being configured to abut against the back side of the upper cutting blade when the upper cutting blade cuts the electrode tab. When the upper cutting blade cuts the electrode tab, the pusher portion abuts against the side of the upper cutting blade away from the lower cutting blade, reducing deformation of the upper cutting blade during electrode tab cutting, ensuring stability of the upper cutting blade during the cutting process, and improving the cutting accuracy of the electrode tab.
[0004] The aforementioned tab cutting device proposes that when the upper cutter cuts the tab, the pusher part abuts against the side of the upper cutter away from the lower cutter, thereby reducing the deformation of the upper cutter during tab cutting, ensuring the stability of the upper cutter during the cutting process, and improving the cutting accuracy of the tab. However, during use, the material may shift during processing when the tab is being cut, affecting the processing effect. Utility Model Content
[0005] The purpose of this invention is to provide a tab cutting device for pouch batteries, which solves the problem that existing tab cutting devices for pouch batteries are difficult to limit the material.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a tab cutting device for soft-pack batteries, including a worktable;
[0007] The bottom of the workbench is equipped with support legs, and both sides of the top of the workbench are equipped with brackets, with a top plate installed on the top of the brackets.
[0008] A hydraulic rod is installed at the top of the top plate, and a lifting block is installed at the bottom of the hydraulic rod. A blade is installed at the bottom of the lifting block, and a processing plate is installed at the top of the worktable.
[0009] Limiting structures are installed on both sides of the top of the workbench, and the limiting structures include telescopic grooves on both sides of the workbench, with telescopic rods installed inside the telescopic grooves.
[0010] In use, the guide rod first passes through the guide groove inside the lifting block. The guide rod and the guide groove form a sliding structure. The guide rod can guide the lifting of the lifting block. The spring is elastic and can buffer the descent of the lifting block. The hydraulic rod will drive the lifting block to rise and fall. The lifting of the lifting block will drive the blade to rise and fall. The two blades can cut the tab material by rising and falling.
[0011] Furthermore, a fixing screw is installed on one side of the telescopic rod, a fixing plate is installed at the top of the telescopic rod, positioning rods are installed at both ends of the fixing plate, a screw is installed on one side of the fixing plate, and a limit plate is installed at the top of the screw. The material can be clamped in the middle by the limit plate and the fixing plate.
[0012] Furthermore, an anti-slip pad is installed on one side of the limiting plate, and the anti-slip pad is symmetrically distributed about the central axis of the worktable. The protective plate can enhance the friction of the limiting plate.
[0013] Furthermore, the outer side wall of the screw is uniformly provided with external threads, and the inner side wall of the limiting plate is uniformly provided with internal threads that cooperate with the external threads. The screw and the limiting plate are threadedly connected, and the rotation of the screw will drive the limiting plate to rise and fall.
[0014] Furthermore, a guide structure is installed at the top of the processing plate. The guide structure includes guide rods installed on both sides of the top of the processing plate, and springs are provided on the outer side of the guide rods. The guide structure also includes a guide groove inside the lifting block, which can guide the lifting block.
[0015] Furthermore, the lifting block is equipped with an adjustment structure. The adjustment structure includes a moving groove inside the lifting block, connecting rods at both ends inside the moving groove, a threaded rod at the middle position inside the moving groove, and rotating blocks on both sides of the threaded rod. The adjustment structure can adjust the position of the blade.
[0016] Furthermore, the moving groove is provided with a sliding groove inside, and the top of the blade is provided with a slider. The moving groove and the blade form a sliding structure, allowing the blade to slide.
[0017] The advantages of the tab cutting equipment for soft-pack batteries provided by this utility model are as follows: during use, the material can be limited on both sides by the limiting structure to prevent the material from shifting; the lifting block can be guided by the wire structure to prevent the lifting block from shifting during lifting; and the position of the blade can be adjusted by the adjustment structure.
[0018] By installing telescopic grooves on both sides of the workbench, the telescopic grooves and telescopic rods form a sliding structure. The telescopic rods can slide inside the telescopic grooves, and the sliding of the telescopic rods can adjust the height of the top fixed plate, allowing the fixed plate to adapt to different situations. The screw and the limiting plate form a threaded connection. The rotation of the screw can adjust the raising and lowering of the limiting plate. The raising and lowering of the limiting plate can clamp the material in the middle through the limiting plate and the fixed plate. The limiting plate and the fixed plate can limit the material, and the positioning rod can prevent the limiting plate from shifting. This achieves the purpose of facilitating the limiting of materials in the tab cutting equipment for soft-pack batteries.
[0019] By setting a moving groove inside the lifting block, the blade can slide along the moving groove. Twisting the rotating block can drive the threaded rod to rotate. The threaded rod and the blade form a threaded connection. The threads on the threaded rod are symmetrically distributed about the central axis of the threaded rod. The rotation of the threaded rod will drive the blade to move in the opposite direction. The movement of the blade will adjust the gap between the two blades, allowing the blade to adapt to different situations and cut tabs of different sizes. The connecting rod passes through the blade and can prevent the blade from deviating. This achieves the purpose of making it easy to adjust the blade gap in the tab cutting equipment for soft-pack batteries. Attached Figure Description
