Description

Technical Field

[0001] This invention relates to the field of punching dies, and in particular to an automated punching fixture for plastic on batteries. Background Technology

[0002] In the field of automated punching of disc-shaped workpieces, a servo motor is typically used to drive a rotary table for multi-station stepping transmission, which is combined with the upper punching mechanism to perform continuous center punching operations, thereby processing the disc workpiece into a ring-shaped part.

[0003] Existing automated punching equipment generally relies solely on the electromagnetic holding torque of the servo motor to achieve basic positioning of the punching station, and has a conventional one-way ejector plate built into the upper die holder at the punching execution end, in order to scrape off the product attached to the upper die punch after the punching action is completed.

[0004] However, when faced with high-frequency and high-precision actual machining conditions, this conventional system architecture essentially results in a single-axis cantilever structure supporting the material on the rotary table. When the punch press above applies a massive instantaneous punching force downwards, the extreme transient impact often directly exceeds the rigidity limit of the servo motor, forcing the rotary table to undergo microscopic transient torsional yielding and downward deformation. Furthermore, the lack of rigid axial and circumferential physical constraints on the upper and lower dies at the moment of closing causes accumulated mechanical tolerances in the transmission chain to directly lead to slight eccentricity in the punching action, resulting in poor coaxiality of the punched holes in the final product. Summary of the Invention

[0015] Further details: The upper die of the punching die also includes an upper die base; The upper die holder is located between the main spindle and the punch fixing plate; The bottom end face of the spindle is fixedly connected to the top surface of the upper mold base; The top surface of the punch fixing plate is fixedly connected to the bottom surface of the upper die base.

[0016] In summary, the present invention has the following beneficial effects: First, in this invention, the bottom end face of the punching guide post is lower than the bottom end face of the positioning rod, the bottom end face of the positioning rod is lower than the bottom end face of the punch, and the bottom end face of the punch is lower than the bottom end face of the punch. The static height difference decomposes the single downward punching stroke of the main shaft into a physical contact process with strict timing. When the upper die of the punching die moves towards the die closing position, the punching guide post is first inserted into the guide sleeve for initial guidance, then the positioning rod is inserted into the positioning groove to restrict the degree of rotational freedom, then the punch abuts against the upper die of the lower die of the punching die to achieve the pressing of the plastic material placed there, and finally the punch continues to move downward. When processing materials such as plastic on batteries that are not strong enough and are prone to micro-slippage or warping deformation under stress, the structure of this solution can pre-complete the spatial alignment of the mold components, anti-rotation locking, and planar pressing and locking of the plastic surface on the battery by relying on the natural contact sequence of the mechanical structure before the punch actually contacts and punctures the plastic on the battery. This sequential physical action of guiding, anti-rotation, pressing, and finally punching effectively overcomes the problem of hole position deviation caused by material migration during the moment the punch is pressed down in conventional punching equipment, and significantly improves the accuracy and consistency of hole processing.

[0017] The punch retainer plate has a first position away from the punch retainer plate and a second position close to the punch retainer plate, with the stripper spring abutting between the two. Combining with the previous step, when the punch abuts above the lower die of the punching die, the punch retainer plate stops moving downwards due to physical obstruction. At this time, the spindle continues to press down, causing the punch retainer plate to move from the first position to the second position, overcoming the supporting force of the stripper spring. Using the compressed deformation of the stripper spring as the dividing point of the motion sequence, the overall downward movement of the die is transformed into the punch extending outwards relative to the punch. This achieves automatic decoupling of the material clamping action and the cutting and punching action within a single spindle pressing stroke. The reaction force generated after the punch abuts above the lower die of the punching die forces the stripper spring to compress, ensuring that the punch continuously provides a stable, flexible clamping force to the plastic on the battery before and throughout the punching process. This effectively suppresses the radial pulling and tearing deformation of the plastic on the battery when subjected to strong local shearing force from the punch, improving the smoothness of the cut edge.

[0018] When the upper die of the punching die is in the closed position, the punching guide post, positioning rod, punch, and punch each perform their respective functions and cooperate with each other. At this time, the cooperation between the guide sleeve and the punching guide post eliminates horizontal offset, the cooperation between the positioning groove and the positioning rod eliminates circumferential offset, and the punch completes the vertical end face contact. Multi-dimensional rigid constraints are established between the upper and lower dies, so that the punch is in a stable spatial mechanical environment at the moment it enters the cavity to cut, effectively absorbing and isolating the uneven lateral shear force that may be generated when punching thin plastic on the battery.

[0019] Secondly, in this invention, by integrating the guide sleeve, positioning groove, and cavity onto the lower die core, and by setting an elastic element that abuts against the bottom end of the guide sleeve and the bottom wall of the mounting hole in the mounting hole of the lower die of the punching die, when the plastic on the battery is being stamped, when the punch abuts against the top of the lower die core and the punch penetrates into the cavity, the instantaneous rigid impact load generated by the upper die pressing down will directly compress the elastic element through the guide sleeve to produce compression deformation, effectively absorbing and weakening the destructive impact force transmitted from the main shaft to the lower die of the punching die, reducing the structural damage caused by rigid collisions to the die components, and improving the fatigue resistance of the tooling during continuous operation.

[0020] The lower die of the punching die has a mounting hole, the central axis of which is collinear with the central axis of the guide sleeve. An elastic element is installed inside the mounting hole, abutting against the bottom wall of the mounting hole and the bottom end of the guide sleeve. When the upper die closes downwards and presses against the lower die core, the lower die core is subjected to force, transmitting pressure to the bottom end of the guide sleeve, which in turn forces the elastic element inside the mounting hole to undergo compressive deformation. The collinear design ensures that the axial impact force transmitted by the upper die acts perpendicularly on the deformation axis of the elastic element. As the upper die disengages from the lower die and moves towards the open position, the elastic element releases its stored elastic potential energy, applying an upward reaction force to the bottom end of the guide sleeve, driving the lower die core to produce an upward reset motion. This instantaneous reset action is converted into a physical vibration demolding force. When plastic material is punched in a battery, it often gets stuck at the edge of the cavity or adheres to the surface of the lower mold core due to the expansion of the material deformation. This upward rebound acceleration can break the interference friction state or surface adhesion state between the plastic material and the lower mold core, and improve the smoothness of demolding of thin plastic parts.

[0021] Third, by setting a downwardly protruding blanking flange and an upwardly recessed pressure relief cavity on the bottom end face of the punch, and setting a matching annular groove on the top surface of the lower die core, before stamping the plastic on the sheet-like battery, when the upper die of the punching die is in the closed position and the punch fixing plate is in the first position, the blanking flange is inserted into the annular groove, forcing the plastic on the battery around the hole to be processed to be firmly locked. This makes the central area located directly below the pressure relief cavity and not yet contacted by the punch in a highly taut stress state. By physically tensioning the plastic material on the battery around the periphery and placing the center in a suspended and yielding stress boundary condition, and with the punch fixing plate moving to the second position, the bottom end face of the punch passes through the pressure relief cavity and extends into the cavity, forming a tear-resistant stamping sequence of physical tension followed by cutting and puncturing. When the plastic on the battery, under high tension, is subjected to vertical shearing force applied by the punch, any micro-wrinkles that may exist within the material are eliminated in advance, allowing the punch to perform a clean cut. This suppresses the wire drawing or serrated tearing of the hole edge caused by the material sinking and deforming under the force of the punch, significantly improving the smoothness and processing quality of the plastic punched cross-section.

[0022] Fourth, in this invention, by creating a cutting edge avoidance stepped groove in the downward recess between the annular groove and the cavity on the top surface of the lower mold core, and ensuring that the projection of the inner sidewall of the pressing flange is outside the outer boundary of the cutting edge avoidance stepped groove in the mold-closed state, and by maintaining a bidirectional gap between the bottom end face of the pressing flange and the top edge of the cavity in both horizontal and vertical directions, the mechanical impact and vertical extrusion stress transmitted by the pressing flange to the cutting edge of the cavity when pressing and locking the plastic on the battery are blocked. This prevents rigid collisions and frictional interference to the cutting part of the lower mold during pressing, and reduces the risk of cutting edge chipping and wear under high-frequency stamping conditions.

[0023] Fifth, in this invention, a material-gathering dome cavity is formed by indenting the center of the bottom end face of the punch, and an acute-angled cutting edge is set around the material-gathering dome cavity at the edge of the bottom end face of the punch. At the same time, an exhaust channel is opened inside the punch, with one end connected to the material-gathering dome cavity and the other end penetrating to the outer surface of the punch. The acute-angled cutting edge guides the cut plastic waste on the battery to arch and avoid deformation inside the material-gathering dome cavity. In conjunction with the exhaust channel, a breathing channel is established between the inside of the material-gathering dome cavity and the outside atmosphere. This breaks the vacuum pressure adsorption state generated between the bottom end face of the punch and the plastic waste on the battery at the moment of punching and cutting. It weakens the physical adhesion and traction effect of negative pressure on the plastic waste on the thin battery, improves the phenomenon of plastic waste adhering and carrying on the battery when the punch returns, and improves the smoothness of the waste falling into the material drop channel and the reliability of automated continuous punching operation.

[0024] Sixth, in this invention, by setting up a servo rotary bearing module and distributing loading, punching, unloading, and zeroing stations sequentially around the rotation center of the rotary table, and installing punching die lower molds at each station, when the servo motor drives the rotary table to rotate, the multiple punching die lower molds at different stations can synchronously and independently receive the corresponding action commands, transforming the single-station in-place serial waiting processing mode into a multi-station synchronous flow execution mode. This reduces the idle cycle of the stamping execution module waiting for the plastic on the battery to be loaded and unloaded, significantly improving the overall cycle time and continuous production efficiency of the tooling.

[0025] By placing the stamping execution module directly above the punching station and using a servo motor to drive the rotary table to sequentially position the lower die of the punching die at each station, physical isolation between the punching action and material transfer in this space is achieved. When processing the thin plastic on a lightweight battery that is highly susceptible to stress and displacement, the mechanical vibration and vertical stress generated by the downward pressure of the stamping execution module on the lower die of the punching die are constrained to a local area of ​​the punching station. This reduces the disturbance of mechanical impact on the lower die of the punching die and the plastic material at the loading and unloading stations, ensuring the positional stability and punching accuracy of the material during station flow.

[0026] Seventh, in this invention, a lifting and guiding structure is formed by using a first lifting guide column and a first lifting guide plate, and the loading rotary cylinder and loading rotary swing arm are integrally supported on the top surface of the first lifting guide plate, thus achieving a decoupled lifting and rotation handling structure. When handling lightweight plastic materials on batteries that are easily affected by airflow or mechanical vibration, the rigid first lifting guide column absorbs the vibration generated by the loading suction cup during the gripping and lowering process, avoiding the coupling interference between horizontal rotational inertia and vertical lifting impact force, improving the stability when picking up and placing plastic materials, and effectively reducing the defects of material and workpiece position shift caused by vibration during the handling process.

[0027] By directly mapping the first and second rotation positions of the loading rotary arm to the area directly above the loading and unloading stations, and coordinating this with the rising and falling positions of the first lifting guide plate, the complex material transfer process is transformed into a two-dimensional discrete motion constrained by purely mechanical limit endpoints. Static spatial geometric alignment replaces dynamic servo trajectory interpolation, which is prone to cumulative errors. This effectively resists the attenuation of positioning accuracy caused by pneumatic component wear while ensuring long-term high-frequency operation of the automated punching fixture, guaranteeing that the plastic on the battery accurately falls into the cavity of the lower die of the punching mold.

[0028] By installing feeding suction cups at both ends of the rotating arm, a dual-end alternating parallel feeding structure is formed. During the handling operation, the single-time switching of the rotating arm's position can simultaneously meet the dual process requirements of gripping the plastic to be processed and delivering the already transported plastic to the stamping station, eliminating the ineffective travel time of the feeding suction cups returning unloaded in single-arm handling mechanisms. This synchronous alternating operation mode significantly shortens the cycle time of the feeding and transfer module, enabling it to match the high-speed multi-station flow efficiency of the servo rotary bearing module and improving the overall productivity of the automated punching fixture.

[0029] Eighth, in this invention, by using a second lifting guide post in conjunction with a second lifting guide plate, and mounting the material discharge rotary cylinder and the material discharge rotary swing arm on the top surface of the second lifting guide plate, when extracting the plastic on the battery that is prone to interference friction or jamming with the inner wall of the mold cavity after being punched, the rigid second lifting guide post provides extremely strong vertical guiding support, ensuring that the material discharge tension sleeve will not tilt or shake when it forcibly pulls out the material from the descending position to the ascending position with the second lifting guide plate, reducing the risk of secondary tearing or edge damage of thin-walled plastic material during demolding due to uneven force.

[0030] By setting the unloading extraction actuator as an unloading tensioning sleeve and statically projecting it above the unloading station and subsequent unloading station using the third and fourth rotary positions, internal support extraction and fixed-point transfer are performed for perforated plastic parts. Utilizing the holes already punched into the workpiece for internal tensioning extraction improves the success rate of removing the stamped finished product and the accuracy of unloading and positioning.

[0031] By fixing feeding tension sleeves to both ends of the feeding rotary arm, a double-ended synchronous alternating flow unloading structure is formed. This allows the feeding and transfer module to process the actions of placing the extracted material at the subsequent feeding station and preparing for the next extraction at the feeding station in parallel during a single rotation stroke, eliminating the ineffective stroke of a single actuator turning back empty between two stations. This synchronous parallel operation mode significantly shortens the feeding and transfer cycle time, enabling it to closely connect with the high-frequency processing cycle of the stamping actuator module, and improving the overall production continuity and output efficiency of the automated punching fixture.

The stamping execution module 400 is vertically positioned directly above the punching station 320, corresponding vertically to the lower die 303 located at the punching station 320. A servo motor 301 drives the rotary table 302 to rotate in the horizontal plane, causing any lower die 303 to be sequentially positioned at the loading station 310, punching station 320, unloading station 330, and zeroing station 340 as the rotary table 302 rotates.

[0039] The surface of the workbench 100 is also provided with loading pre-processing stations 600.

An unloading transfer module 500 is located in the area between the unloading stations 330 and the subsequent unloading stations 700 on the surface of the workbench 100. The subsequent unloading station 700 can be an inclined guide chute with baffles on both sides, a funnel-shaped collection chute, or an input end baffle for a horizontally connected conveyor belt.

[0042] like Figure 3 and Figure 4 As shown, the internal components of the material feeding and transfer module 200 include a first lifting guide column 201, a first lifting guide plate 202, a feeding rotary cylinder 203, a feeding rotary drum 204, a feeding rotary swing arm 205, a feeding suction cup 206, and a feeding cylinder 207.

The feeding cylinder 207 is vertically arranged and fixedly connected to the bottom of the worktable 100. The output end of the feeding cylinder 207 extends vertically upward and is fixedly connected to the bottom surface of the first lifting guide plate 202.

[0044] A feeding rotary cylinder 203 is horizontally arranged and fixedly connected to the top surface of the first lifting guide plate 202. The bottom end of the feeding rotary cylinder 204 is fixedly connected to the output end of the feeding rotary cylinder 203 and extends vertically upward. A feeding rotary swing arm 205 is horizontally arranged and fixedly connected to the top of the feeding rotary cylinder 204. At least two feeding suction cups 206 are provided. Multiple feeding suction cups 206 are respectively vertically and fixedly connected to the two ends of the horizontally extending feeding rotary swing arm 205.

[0045] The first lifting guide plate 202 has an upward position along the first lifting guide column 201 in the vertical direction, which is upward away from the worktable 100, and a downward position that is downward towards the worktable 100. The loading rotary swing arm 205 has a first rotation position and a second rotation position in the horizontal plane.

The positioning rod 419 is fixedly connected to the bottom surface of the punch fixing plate 413 and extends vertically downwards.

[0055] The punch fixing plate 412 has a first position in the vertical direction, moving upward away from the punch fixing plate 413, and a second position, moving downward towards the punch fixing plate 413. When the punch fixing plate 412 is in the first position, the various overhanging components at the bottom of the upper die 410 of the punching die exhibit a height difference distribution: the bottom end face of the punching guide post 415 is lower than the bottom end face of the positioning rod 419, the bottom end face of the positioning rod 419 is lower than the bottom end face of the punch 414, and the bottom end face of the punch 414 is lower than the bottom end face of the punch 416.

[0056] The upper die 410 of the punching die has an opening position that moves upward away from the lower die 303 of the punching die, and a closing position that moves downward toward the lower die 303 of the punching die. When the upper die 410 of the punching die moves downward and is in the closing position, the bottom end of the punching guide post 415 is inserted into the guide sleeve 307 from top to bottom, and the bottom end of the positioning rod 419 is inserted into the positioning groove 350 from top to bottom; the bottom surface of the punch 414 abuts against the upper surface of the lower die 303 of the punching die, and the punch fixing plate 412 moves downward to the second position, and the bottom end face of the punch 416 extends vertically downward from the bottom end face of the punch 414 and penetrates vertically into the cavity 305.

[0057] In this embodiment, the unloading spring 417 can be, for example, a helical cylindrical compression spring, a polyurethane rubber spring, or a nitrogen cylinder spring.

[0058] The upper die 410 of the punching die also includes an upper die base 411. The upper die base 411 is horizontally arranged and located between the main spindle 401 and the punch fixing plate 412, serving as an intermediate connecting base. The main spindle 401 is vertically arranged, and its bottom end face is fixedly connected to the top surface of the upper die base 411. The punch fixing plate 412 is horizontally arranged, and its top surface is fixedly connected upward to the bottom surface of the upper die base 411.

[0059] The lower die 303 of the punching die includes a lower die core 304 inside. A guide sleeve 307, a positioning groove 350, and a cavity 305 are all arranged on the lower die core 304. The guide sleeve 307 and the positioning groove 350 extend vertically downward from the top surface of the lower die core 304, and the cavity 305 is recessed downward from the top surface of the lower die core 304.

[0060] The lower die 303 of the punching die also has a vertically formed mounting hole 308 inside, and the lower die 303 of the punching die also includes an elastic element 309 inside. The mounting hole 308 is located directly below the guide sleeve 307, and the central axis of the mounting hole 308 and the central axis of the guide sleeve 307 are on the same straight line in the vertical direction and remain collinear.

[0061] The elastic element 309 is vertically installed inside the mounting hole 308. The bottom end of the elastic element 309 abuts against the inner bottom wall of the mounting hole 308, and the top end of the elastic element 309 abuts against the bottom end face of the guide sleeve 307.

[0062] In this embodiment, the specific structure of the elastic element 309 can be a helical cylindrical compression spring, a disc spring, a polyurethane rubber spring, or a nitrogen spring.

[0063] The lower mold core 304 includes a vertically formed blanking channel 306. The blanking channel 306 is positioned directly below the cavity 305. The top opening of the blanking channel 306 extends upwards and directly connects to the bottom region of the cavity 305. The bottom end of the blanking channel 306 extends downwards and vertically penetrates the bottom surface of the lower mold core 304, forming a vertically continuous spatial path. The inner wall of the blanking channel 306 is a conical surface that extends sloping outwards from top to bottom. Furthermore, the cross-sectional inner diameter of the blanking channel 306 in the horizontal direction gradually increases from top to bottom.

[0064] like Figure 6 , Figure 7 and Figure 8 As shown, the interior of the punch 414 includes a blanking flange 420 and a pressure relief cavity 421. The bottom edge of the punch 414 protrudes vertically downwards, forming a closed blanking flange 420. The central area of ​​the bottom surface of the punch 414 is vertically recessed upwards, forming the pressure relief cavity 421. The punch 416 is arranged vertically, and the bottom surface of the punch 416 is spatially positioned directly above the pressure relief cavity 421.

[0065] The lower mold core 304 includes an annular recess 352 inside. The top surface of the lower mold core 304 is vertically recessed to form the annular recess 352. The annular recess 352 is arranged in a surrounding shape on the horizontal plane and is located around the periphery of the cavity 305.

[0066] When the upper die 410 of the punching die moves downward and is in the closed position, and the punch fixing plate 412 is in the first position in the vertical direction, the pressing flange 420 at the bottom of the punch 414 is vertically inserted into the annular recess 352 from top to bottom, and the bottom end face of the punch 416 remains suspended and stays in the pressure relief cavity 421.

[0067] When the upper die 410 of the punching die is kept in the closed position and the punch fixing plate 412 moves downward and is in the second position, the bottom end face of the punch 416 penetrates the pressure relief cavity 421 vertically from top to bottom, and the bottom end face of the punch 416 extends further downward vertically into the cavity 305.

[0068] In this embodiment, the closed-form pressing flange 420 and the annular groove 352 that are spatially inserted and matched with it can have cross-sectional profiles in the horizontal direction that are, for example, continuously closed circular rings, continuously closed rectangular frames, or continuously closed elliptical rings. The specific cross-sectional geometry can be machined and formed according to the mold profile required for machining by CNC milling process.

[0069] like Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the top surface of the lower mold core 304 is recessed downward between the annular recess 352 and the cavity 305 and has a cutting edge avoidance stepped groove 351.

[0070] The upper die 410 of the punching die includes a blanking flange 420 inside. When the upper die 410 of the punching die moves downward and is in the closed position, and the blanking flange 420 is inserted into the annular recess 352 from top to bottom, the inner sidewall of the blanking flange 420 generates a projection in the vertical direction. The projection of the inner sidewall of the blanking flange 420 in the vertical direction is specifically located outside the outer boundary of the cutting edge avoidance stepped groove 351.

[0071] The bottom end face of the pressing flange 420 and the top edge of the cavity 305 do not contact each other in space, and the bottom end face of the pressing flange 420 and the top edge of the cavity 305 are separated by a gap in the horizontal and vertical directions.

[0072] In this embodiment, the cross-sectional geometry of the cutting edge avoidance stepped groove 351 in the horizontal direction can be exemplified as a continuously closed annular stepped groove or a continuously closed rectangular frame-shaped stepped groove. The gap between the bottom end face of the pressure flange 420 and the top edge of the cavity 305 in the horizontal and vertical directions can be exemplified as a set distance between 0.1 mm and 0.5 mm.

[0073] like Figure 6As shown, the punch 416 has a bottom end face, and the middle of the bottom end face of the punch 416 is concave upward in the vertical direction to form a hollow material-gathering dome cavity 423. The bottom end face of the punch 416 is provided with an acute-angled cutting edge 424, which is arranged in a closed ring on the horizontal plane and distributed around the material-gathering dome cavity 423, forming a spatial orientation surrounding the material-gathering dome cavity 423.

[0074] The punch 416 has an exhaust channel 425 inside. The exhaust channel 425 extends inside the punch 416. One end of the exhaust channel 425 is connected to the material dome cavity 423, and the other end of the exhaust channel 425 extends outward and directly penetrates the outer surface of the punch 416.

[0075] In this embodiment, the cutting edge angle of the acute-angle cutting blade 424 can be, for example, a set acute angle between thirty and sixty degrees. The specific location where the venting channel 425 extends to the outer surface of the punch 416 can be, for example, the side surface or the top surface of the punch 416. The number of venting channels 425 can be, for example, a single channel, or multiple micro-hole channels arranged in a ring array around the central axis of the punch 416.

[0076] In this embodiment, the exhaust duct 425 and the cylinders involved are all connected to an external air source. The loading suction cup 206 and the unloading tension sleeve 506 are each connected to a different air source. When compressed gas is introduced into the unloading tension sleeve 506 and it expands radially, the elastic rubber on the periphery of the unloading tension sleeve 506 will expand evenly in all directions, exerting force outward from the inner hole of the finished product to fix the processed product.

[0077] The above embodiments are merely explanations of the present invention and are not intended to limit the present invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
