Description

Technical Field

[0001] This utility model belongs to the field of battery processing and molding technology, and in particular relates to a battery cover molding device. Background Technology

[0002] As a key packaging component, the button battery cover typically has a U-shaped cross-section, with its edges requiring precision stamping to form an annular protrusion to match the battery casing. Traditional stamping mechanisms mainly consist of an upper die, a lower die, and a punch. During processing, the punch applies vertical pressure to the metal sheet, causing the material to plastically deform along the die cavity to form the target contour. The forming of the protruding ring relies on the precise control of the fit between the punch and the lower die. This mechanical stamping method relies on the rigid fit of a pre-set die to complete the forming process, and the overall process flow is relatively fixed.

[0003] In existing technologies, stamping mechanisms lack dynamic compensation capabilities for initial workpiece positioning deviations. When the button battery cover skews within the mold, the vertical force direction of the punch misaligns with the actual position of the workpiece, causing axial tilting or radial displacement of the forming ring. Such defects directly affect the sealing performance of the battery cover and housing assembly. Traditional equipment often relies on manual re-inspection or additional visual inspection systems for post-processing screening, failing to correct forming deviations in real time during the stamping process. This passive approach increases the scrap rate and hinders further improvements in production cycle time, making it difficult to meet the large-scale manufacturing demands of high-precision battery components. Utility Model Content

[0004] The purpose of this invention is to provide a battery cover forming device, which aims to solve the problem in existing battery cover stamping equipment where the vertical force direction of the punch is misaligned with the actual position of the workpiece, resulting in axial tilting or radial displacement of the forming ring. This defect directly affects the sealing performance of the battery cover and the housing.

[0005] To achieve the above objectives, this utility model provides a battery cover forming device, including an upper stamping die, a lower stamping die, and an adapter mechanism.

[0008] Optionally, the first guide portion includes a first movable block and a first elastic element. The inner wall of the movable groove is provided with a first sliding groove.

[0011] Optionally, the horizontal guide assembly includes a movable seat, a first guide portion, and a second guide portion.

The guiding directions of the first guide portion and the second guide portion are perpendicular to each other. The movable seat is slidably connected to the first guide portion and the second guide portion. The rotating assembly is disposed on the movable seat. When the output end of the stamping die applies a stamping force to the rotating assembly, the output end of the rotating assembly rotates at an adaptive angle according to the shape of the battery cover and transmits the stamping force to the first guide portion and the second guide portion.

[0015] The battery cover forming device provided in this utility model embodiment has at least one of the following technical effects: by dynamically adjusting the spatial posture of the battery cover during the stamping process, the tilting defect of the convex ring caused by workpiece skewing during traditional stamping is effectively solved. When the upper stamping die applies pressure to the battery cover in the mounting groove, the adapter mechanism generates a composite motion of horizontal sliding and rotation in the movable groove: the lateral component of the stamping force drives the adapter mechanism to translate along the movable groove, while the torque transmission of the contact surface forces the adapter mechanism to rotate around the contact point, so that the battery cover carried by the mounting groove changes its tilt angle in real time, and finally the action direction of the upper stamping die is automatically adjusted to be perpendicular to the plane of the battery cover. This process achieves adaptive correction of the stamping force direction through a purely mechanical structure, dynamically eliminating the initial positioning deviation of the workpiece and the cumulative deformation error during the stamping process at the moment of stamping, ensuring that the forming direction of the edge convex ring is always perpendicular to the main plane of the battery cover, avoiding battery assembly interference problems caused by the tilting of the convex ring, and eliminating the need for additional detection sensors or electronic control systems. While ensuring forming accuracy, it maintains the simplicity and reliability of the stamping mechanism and is suitable for high-speed continuous stamping operation environments.

Detailed Implementation

[0023] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-5 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0024] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, such as Figures 1-5 As shown, a battery cover forming apparatus is provided, including an upper stamping die 100, a lower stamping die 200, and an adapter mechanism 300. The lower stamping die 200 is disposed on the stamping path at the output end of the upper stamping die 100. The adapter mechanism 300 is movably connected to the lower stamping die 200, and the adapter mechanism 300 is provided with a mounting groove 400 for loading the battery cover to be formed. The lower stamping die 200 is provided with a movable groove 500 for accommodating the adapter mechanism 300. The adapter mechanism 300 can be slidably connected in the movable groove 500 in the horizontal direction. The end of the adapter mechanism 300 used for loading the battery cover can rotate and move after being stamped by the output end of the upper stamping die 100, so that the orientation angle of the mounting groove 400 changes.

[0028] By dynamically adjusting the spatial orientation of the battery cover during the stamping process, the tilting defect of the convex ring caused by workpiece skewing during traditional stamping is effectively solved. When the upper stamping die 100 applies pressure to the battery cover in the mounting groove 400, the adapter mechanism 300 generates a combined horizontal sliding and rotational motion in the movable groove 500: the lateral component of the stamping force drives the adapter mechanism 300 to translate along the movable groove 500, while the torque transmission of the contact surface forces the adapter mechanism 300 to rotate around the contact point, causing the battery cover supported by the mounting groove 400 to change its tilt angle in real time, ultimately making the direction of action of the upper stamping die 100 automatically adjust to be perpendicular to the plane of the battery cover. This process achieves adaptive correction of the stamping direction through a purely mechanical structure, dynamically eliminating the initial positioning deviation of the workpiece and the cumulative deformation error during the stamping process at the instant of stamping. This ensures that the forming direction of the edge protrusion is always perpendicular to the main plane of the battery cover, avoiding battery assembly interference caused by the tilt of the protrusion. At the same time, no additional detection sensors or electronic control systems are required. While ensuring forming accuracy, the simplicity and reliability of the stamping mechanism are maintained, making it suitable for high-speed continuous stamping operations.

[0029] like Figures 1-5As shown, in another embodiment of the present invention, the adapter mechanism 300 includes a horizontal guide component 310 and a rotating component 320. The horizontal guide component 310 is disposed in the movable groove 500, and the rotating component 320 is disposed at the output end of the horizontal guide component 310. The mounting groove 400 is formed at the end of the rotating component 320 away from the horizontal guide component 310, and the output end of the horizontal guide component 310 can move freely along the horizontal two-axis direction.

[0030] The horizontal guide component 310 allows the adapter mechanism 300 to translate freely in any horizontal direction via dual-axis free movement. The rotating component 320 synchronously adjusts the angle of the mounting groove 400. When the stamping die 100 contacts the skewed battery cover, the horizontal guide component 310 absorbs the lateral displacement, and the rotating component 320 adaptively rotates according to the change in the contact surface angle. The two work together to eliminate workpiece skew. Compared with traditional fixed fixtures that rely solely on mold cavity constraints, this embodiment actively compensates for dynamic offsets during the stamping process through a composite motion mechanism, solving the problem of convex ring tilting caused by workpiece placement deviations or press vibration, and significantly improving forming consistency.

[0031] like Figures 1-5 As shown, in another embodiment of this utility model, the horizontal guide component 310 includes a movable seat 311, a first guide portion 312, and a second guide portion 313. The first guide portion 312 is disposed in the movable groove 500, and the second guide portion 313 is slidably connected to the first guide portion 312. The movable seat 311 is fixedly installed on the second guide portion 313. The guiding direction of the first guide portion 312 and the moving direction of the second guide portion 313 are perpendicular to each other. The rotating component 320 is disposed on the movable seat 311.

[0032] The first guide portion 312 slides along a first direction, and the second guide portion 313 slides along an orthogonal direction, forming a cross-shaped slide rail structure. During stamping, the deflection force of the battery cover is decomposed into two orthogonal components, which drive the first guide portion 312 and the second guide portion 313 to slide, thereby causing the moving seat 311 to complete displacement adjustment in any direction within the plane. Traditional single-degree-of-freedom guiding mechanisms cannot cover multi-directional offsets. This embodiment achieves full-plane correction through orthogonal sliding pairs, solving the problem of uneven local force caused by the uncertain tilt direction of the workpiece, and ensuring that the stamping force is evenly transmitted to the edge of the battery cover.

[0033] like Figures 1-5As shown, in another embodiment of this utility model, the first guide portion 312 includes a first moving block 314 and a first elastic member 315. The inner wall of the movable groove 500 is provided with a first sliding groove 316. The first moving block 314 is slidably connected in the first sliding groove 316. The two ends of the first elastic member 315 are respectively fixedly connected to the groove wall of the first moving block 314 and the first sliding groove 316. There are two sets of the first elastic members 315, and the two sets of the first elastic members 315 are distributed at both ends of the first moving block 314. There are two sets of the first guide portion 312, and the two sets of the first guide portion 312 are respectively installed in the corresponding first sliding groove 316. The two ends of the second guide portion 313 are respectively fixedly connected to the corresponding first moving block 314.

[0034] The first moving block 314 slides along the first groove 316 under the constraint of the first elastic members 315 on both sides. When the stamping force is applied, the first elastic member 315 deforms under pressure to store energy. After the stamping is completed, the elastic member releases energy to push the moving block to reset. Traditional rigid guiding mechanisms lack flexible reset capability. This embodiment achieves adaptive displacement and automatic reset through bidirectional elastic constraints, solving the problem of continuous processing error accumulation caused by residual offset of the fixture position after stamping, and ensuring the positioning repeatability accuracy in mass production.

[0035] like Figures 1-5 As shown, in another embodiment of the present invention, a rotating shaft 317 is provided in the first groove 316, the first moving block 314 is slidably connected to the rotating shaft 317, and the first elastic element 315 is a compression spring, which is wound around the rotating shaft 317.

[0036] The pivot 317 restricts the first moving block 314 to slide only along the axial direction. The coiled compression spring generates a torsional restoring force when the moving block slides, enhancing the reset stability. Traditional linear springs are prone to bending failure due to lateral forces. In this embodiment, the helical cooperation between the pivot 317 and the spring solves the problem of guide jamming caused by the deformation of the elastic element under lateral forces, thus improving the durability of the mechanism.

[0037] like Figures 1-5As shown, in another embodiment of this utility model, the second guide portion 313 includes a second sliding shaft 331, a second moving block 332, and a second elastic member 333. The end of the second sliding shaft 331 is fixedly connected to the first guide portion 312. The second moving block 332 is slidably connected to the second sliding shaft 331. The moving seat 311 is fixedly disposed on the second moving block 332. The moving direction of the second moving block 332 is perpendicular to the guiding direction of the first guide portion 312. The second elastic member 333 is disposed on the second sliding shaft 331 and is drivenly connected to the second moving block 332.

[0038] The second sliding shaft 331 is arranged perpendicularly to the first guide portion 312. When the second moving block 332 slides along the sliding shaft, the impact force is buffered by the second elastic element 333. Traditional orthogonal slide rails lack flexible connections. In this embodiment, the elastic element absorbs the high-frequency vibration during the stamping process, solving the problem of component wear caused by rigid collisions in the multi-directional adjustment mechanism and extending its service life. At the same time, the second elastic element 333 is used to drive the second moving block 332 back to its original position to ensure processing accuracy. The second elastic element 333 is a compression spring. In other embodiments, the second elastic element 333 can also be a rare earth magnet with the same magnetic poles on the second moving block 332 and the first guide portion 312.

[0039] like Figures 1-5 As shown, in another embodiment of this utility model, the horizontal guide component 310 includes a movable seat 311, a first guide portion 312, and a second guide portion 313. The first guide portion 312 slides within the movable groove 500, and the second guide portion 313 is slidably connected within the movable groove 500. The guiding directions of the first guide portion 312 and the second guide portion 313 are perpendicular to each other. The movable seat 311 is slidably connected to the first guide portion 312 and the second guide portion 313. The rotating component 320 is disposed on the movable seat 311. When the output end of the stamping die 100 stamps on the rotating component 320, the output end of the rotating component 320 rotates at an adaptive angle according to the shape of the battery cover and transmits the stamping force to the first guide portion 312 and the second guide portion 313. The first guide portion 312 and the second guide portion 313 move and adjust along a preset direction.

[0040] The rotating assembly 320 converts the angular deviation of the punching force into a coordinated displacement of the first guide portion 312 and the second guide portion 313, which is then offset by the bidirectional sliding of the moving seat 311. Traditional fixtures rely on compensation in a single direction. This embodiment achieves bidirectional adjustment through force transmission path design, solving the problem of incomplete correction under complex deviation conditions and ensuring precise verticality of the convex ring forming direction.

[0041] like Figures 1-5 As shown, in another embodiment of this utility model, the first guide portion 312 and the second guide portion 313 are both arranged in a linear shaft shape. The two ends of the first guide portion 312 and the second guide portion 313 are respectively slidably connected to the inner wall of the movable groove 500. The staggered position of the first guide portion 312 and the second guide portion 313 is slidably connected to the movable seat 311. The inner wall of the movable groove 500 is provided with a reset component for driving the first guide portion 312 and the second guide portion 313 to reset.

[0042] A linear shaft-shaped guide portion forms a planar sliding pair. After stamping, the reset component pulls the guide portion back to its initial position. Traditional reset mechanisms rely on manual intervention. This embodiment achieves fully automatic position recovery through a built-in reset component, solving the problem of batch product scrapping caused by jig failure during continuous stamping and improving production efficiency.

[0043] like Figures 1-5 As shown, in another embodiment of this utility model, the rotating assembly 320 includes a base 321, a universal transmission assembly 322, a third elastic element 323, and a rotating seat 324. The base 321 is fixedly disposed at the output end of the horizontal guide assembly 310. The rotating seat 324 is rotatably connected to the base 321 through the universal transmission assembly 322. The third elastic element 323 is disposed between the base 321 and the rotating seat 324. There are multiple sets of the third elastic elements 323. All the third elastic elements 323 are always used to drive the rotating seat 324 to return to a horizontal state. The mounting groove 400 is formed on the rotating seat 324. The third elastic element 323 is a rare earth magnet; the number of the third elastic elements 323 is an even number and at least four. All the third elastic elements 323 are evenly distributed on the rotating seat 324 and the base 321. The third elastic elements 323 on the rotating seat 324 and the third elastic elements 323 on the base 321 have opposite magnetic poles with the same magnetic polarity. All the third elastic elements 323 are evenly distributed circumferentially along the edge of the mounting groove 400.

[0044] The repulsive force between like magnetic poles creates an automatic reset torque for the rotating seat 324. When the external stamping force disappears, the magnetic force drives the rotating seat 324 to quickly return to a horizontal state. Traditional mechanical springs are prone to fatigue failure. This embodiment solves the problem of short lifespan of elastic elements by using non-contact magnetic reset. At the same time, the uniform distribution of magnetic force avoids angular deviation during the reset process, ensuring the long-term stability of the fixture.

[0045] like Figures 1-5As shown, in another embodiment of this utility model, the universal transmission assembly 322 includes a limiting magnetic component 325 and a magnetically conductive ball 326. The limiting magnetic component 325 is in two sets, and the two sets of limiting magnetic components 325 are respectively fixedly disposed on the base 321 and the rotating seat 324. The magnetically conductive ball 326 is magnetically connected between the two sets of limiting magnetic components 325. The base 321 and the rotating seat 324 are provided with arc-shaped grooves at their opposite ends. The limiting magnetic component 325 is a rare earth magnet and is located on one side of the arc-shaped groove. The inner wall of the arc-shaped groove fits the shape of the magnetically conductive ball 326. The two ends of the magnetically conductive ball 326 are slidably connected in the corresponding arc-shaped grooves.

[0046] The magnetically guided ball 326 rolls within the arc-shaped groove, enabling the rotating seat 324 to rotate in multiple directions. The magnetic attraction of the limiting magnetic component 325 constrains the displacement range of the ball. Traditional universal joint structures suffer from frictional losses. This embodiment reduces frictional resistance through magnetic guidance and rolling contact, solving the problem of jamming in the rotating mechanism. At the same time, the magnetic limiting prevents damage to the mechanism caused by excessive rotation, enhancing reliability.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
