[0066] Further applications of this disclosure will become apparent from the detailed description, claims, and drawings. The detailed description and specific examples are intended for illustrative purposes only and are not intended to limit the scope of this disclosure. Attached Figure Description
[0067] This disclosure will be understood more fully from the detailed description and accompanying drawings, in which:
[0068] Figure 1 This is a perspective view of an example stamping press;
[0069] Figure 2 The illustration shows a cross-sectional view of the upper part and a portion of the lower part of the die of a stamping press;
[0070] Figure 3 A cross-sectional view including the upper part and a portion of the lower part of the die of a stamping press;
[0071] Figure 4 This is an exploded perspective view of an example embodiment of the drawing flow into the sensor from the lower part of the mold;
[0072] Figure 5 This is a functional block diagram of an example mold alignment system; and
[0073] Figure 6 Includes example pull-in flow mapping.
[0074] In the accompanying drawings, reference numerals may be used repeatedly to identify similar and / or identical elements. Detailed Implementation
[0075] In a stamping press, the upper and lower portions of a die have complementary shapes. For example, the lower portion of the die may have a convex protrusion extending upward toward the upper portion. The upper portion of the die may have a concave recess into which the convex protrusion extends. The upper and lower portions of the die can be aligned using an expensive and time-consuming process in a die-making machine to prevent the lower portion from contacting the upper portion at one or more locations.
[0076] This application relates to a lower (or upper) portion of a die including a drawing inflow sensor configured to determine the drawing inflow distance and direction of a substrate (e.g., a sheet of metal) during stamping. Based on the drawing inflow values measured on the substrate, adjustments to the upper and / or lower portions of the die can be automatically triggered. This results in better properties of the stamping substrate, such as aesthetic and structural characteristics.
[0077] Figure 1 This is a side perspective view of an example stamping press. The upper portion 104 of the die is mounted to the upper portion 108 of the stamping press. The lower portion 112 of the die is mounted to the lower portion 116 of the stamping press. In this example, the upper portion 108 of the stamping press (and therefore the upper portion 104 of the die) moves vertically upward and downward.
[0078] As the upper portion 104 of the mold moves toward the lower portion 112 of the mold (vertically lowers), the upper portion 104 and the lower portion 112 of the mold stamp a substrate (e.g., a sheet of metal) into the shape of the upper portion 104 and the lower portion 112 of the mold. While an example of the upper portion 104 moving is provided, the lower portion 112 may alternatively be able to move vertically, or both the upper portion 104 and the lower portion 112 may be movable.
[0079] However, the upper portion 104 and the lower portion 112 of the die should not be in direct contact with each other via the substrate. The upper portion 104 and the lower portion 112 of the die are initially positioned such that a predetermined gap (e.g., the same distance) exists uniformly between the surfaces of the upper portion 104 and the lower portion 112 across the die. However, over time, for example due to stamping the substrate, the upper portion 104 and / or the lower portion 112 may move. If the upper portion 104 and the lower portion 112 move to such an extent that they touch each other at one or more locations, one or more components (e.g., the die and / or the stamping press) may flex and / or be damaged. As portions of the substrate are vertically displaced upwards and / or downwards, the stamping of the substrate causes the outer edge of the substrate to move inwards (drawing flow).
[0080] Multiple electric motors 120 control vertical movement. As discussed further below, the operation of the electric motors 120 can be controlled by the motor control module 124 based on the equalization of the drawing flow of the substrate during substrate stamping at multiple (e.g., all) locations on the upper portion 104 and the lower portion 112.
[0081] Figure 2 The illustration shows a cross-sectional view of a portion of an upper portion 104 and a portion of a lower portion 112 of a mold. The upper portion 104 may include one or more recessed features, such as 204. The lower portion 112 may include one or more protruding features, such as 208, configured to extend into the recessed features of the upper portion 104. The upper portion 104 may include one or more protruding features, such as 212. The lower portion 112 may include one or more recessed features, such as 216, configured to extend into the protruding features of the upper portion 104. Generally, the upper portion 104 includes a first feature, and the lower portion 112 includes a second feature complementary to the first feature.
[0082] However, if the upper portion 104 and the lower portion 112 are not properly aligned in one position or move vertically faster than in other positions, one or more portions of the upper portion 104 may come into contact with one or more portions of the lower portion 112, such as... Figure 2As illustrated in the example. Furthermore, during stamping, the drawing inflow distance and / or speed of the substrate may differ at one or more different locations.
[0083] Figure 3 Top perspective view including the lower portion 112 of the mold. An example substrate 304 (e.g., a sheet of metal) to be stamped is shown.
[0084] The substrate 304 includes an outer edge 308 forming the outer periphery of the substrate 304. A drawing flow sensor 312 is disposed in the lower portion 112 of the mold, below the outer edge 308 of the substrate. While examples are provided of four drawing flow sensors disposed around the upper and lower outer edges of the substrate 304 and three drawing flow sensors disposed around the right and left outer edges of the substrate 304, other suitable numbers and / or arrangements of drawing flow sensors may also be used. Furthermore, while an example of a rectangular substrate is provided, this application is also applicable to substrates having other shapes. In various embodiments, one or more drawing flow sensors may be disposed around the outer edge of one or more orifices in the substrate 304. While an example of drawing flow sensors 312 disposed in the lower portion 112 of the mold has been discussed herein, some or all of the drawing flow sensors 312 may be disposed in the upper portion 104 of the mold.
[0085] Figure 4 This is an exploded perspective view of an example implementation of one of the drawing flow sensors 312 (e.g., a sensor module). Each of the drawing flow sensors 312 can be identical.
[0086] The drawn inflow sensor 312 includes a female connector 404 and wires 408 connected to conductive pins of the female connector 404. A nut connects the female connector 404 to a bushing 416. The male connector 420 includes a first conductive pin 424 extending through the bushing and contacting the pins of the female connector 404.
[0087] The male connector 420 also includes second conductive pins 428 that are electrically connected to electrical conductors of a circuit board 432, such as a printed circuit board (PCB). One or more signal processing modules and other types of modules may be implemented on the circuit board 432 and configured to determine, based on signals from the optical sensor 436, the (inward) direction of movement of the outer edge of the substrate at the location where the drawing flows into the sensor, the distance the outer edge moves at that location, the speed (rate) of the outer edge at that location, and the acceleration of the edge at that location. A distance and direction module may determine the direction and distance of movement based on signals from the optical sensor 436. A rate module may determine the speed of movement based on the change of distance over time, for example, by determining a mathematical derivative of the distance or dividing two distances by the time interval between the two measured distances. An acceleration module may determine the acceleration of movement based on the change of velocity over time, for example, by determining a mathematical derivative of the velocity or dividing two velocities by the time interval between the two determined velocities.
[0088] In various embodiments, circuit board 432 and the modules on circuit board 432 may be encased in resin or another suitable type of material. The resin may dampen vibrations and perform one or more other functions. Optical sensor 436 may include an optical (e.g., laser) emitter and an optical receiver. The optical receiver is configured to generate a signal based on light from the emitter being reflected back to the optical receiver. A driver module on circuit board 432 may drive the optical emitter to output light.
[0089] The circuit board 432 may be disposed within the housing 444. The housing 444 may be fastened to the vertical lower side of the lower portion 112 of the mold via one or more fasteners 440, such as screws. One or more fasteners 448, such as screws, may fasten the circuit board 432 and the optical sensor 436 to the housing 444.
[0090] An optical transmitter can emit light through lens 452, and an optical receiver can receive light through lens 452. Lens 452 can be configured not to change the light flux from the optical transmitter to the optical receiver, and can be transparent. A seal 456 can be disposed between lens 452 and optical sensor 436, and can prevent liquids and / or solids from contacting optical sensor 436.
[0091] The membrane 460 protects the outer surface of the lens 452 from contact with substances such as liquids or solids. A membrane support 464 can be provided to support the membrane. The membrane 460 blocks the aperture 468 through which the drawn material flows into the top plate 472 of the sensor 312. Light emitted from the optical emitter travels through the lens 452, through the membrane 460, and through the aperture 468. The light returns to the optical receiver through the aperture 468, the membrane 460, and the lens 452.
[0092] The upper surface 476 is flush with the upper surface of the lower portion 112 of the mold. One or more fasteners 480, such as one or more screws, secure the top plate 472 of the drawn material flowing into the sensor 312 to the top surface of the lower portion 112.
[0093] An O-ring 484 or another suitable type of seal may be provided between the end of housing 444 and the shoulder of bushing 416 to prevent liquid from flowing into circuit board 432.
[0094] While example form factors and fastenings for the drawn inflow sensor are provided, this application is also applicable to other form factors and mounting to the lower portion 112. For example, the housing 444 may be cylindrical and include threads on the outer diameter of the housing 444. The threads on the outer diameter of the housing may engage with threads on the inner diameter of the cylindrical inner bore of the lower portion 112.
[0095] Figure 5 This is a functional block diagram of an example die alignment system. The lower portion 112 (and / or upper portion) of the die includes multiple drawing flow sensors 312.
[0096] The stamping press may include a communication module 504 that receives drawing flow measurement values (e.g., distance, direction, speed, acceleration) 508 measured by the drawing flow sensor 312. The communication module 504 transmits the drawing flow measurement values 508 to the drawing flow module 512. For example, the communication module 504 may transmit the drawing flow measurement values 508 wirelessly via one or more antennas.
[0097] The drawing inflow module 512 can generate a drawing inflow map 516 based on one or more of the drawing inflow measurement value 508 and the positions of the associated drawing inflow sensor 312. The gap map 516 can include, for example, the drawing inflow direction and distance 508 at the coordinates of the drawing inflow sensor 312. For example, the drawing inflow module 512 can interpolate the drawing inflow measurement values between positions. Example mapping is shown in... Figure 6 Provided in [the text]. Figure 6 In the example, the arrow can indicate the direction of the draw flow. The length of the arrow can correspond to the distance the draw flows, for example, increasing with increasing distance and vice versa.
[0098] One or more actions can be taken based on one or more of the drawing inflow measurements 508 and / or mappings 516. For example, motor control module 124 can compare drawing inflow distances and control the power applied to one or more of electric motors 120 based on adjusting these distances to be within a predetermined range. This can include, for example, increasing the speed of the electric motor when the drawing inflow distance near the motor during stamping is greater than one or more other drawing inflow distances 508. As another example, motor control module 124 can decrease the speed of the electric motor when the drawing inflow distance near the electric motor during stamping is less than one or more other drawing inflow distances 508. In other words, motor control module 124 can control motor 120 based on a mapping that achieves the same drawing inflow distance, rate, and acceleration at each drawing inflow sensor.
[0099] As another example of operation, fault module 520 may identify the presence of a fault based on the drawing distance and / or mapping 516. For example, fault module 520 may identify the presence of a fault when one of these distances is greater than or less than the other distances (e.g., average value) by at least a predetermined amount during stamping. As another example, fault module 520 may indicate the presence of a fault when the mapping includes values (e.g., speed) at one or more locations that differ from values (e.g., speed) at other locations of mapping 516 by at least a predetermined amount.
[0100] The fault module 520 can visually or audibly indicate the presence of a fault via one or more output devices 524 (e.g., a display, light / lamp, speaker, or another suitable type of device that outputs sound and / or light). The fault module 520 can additionally or alternatively indicate the presence of a fault to the motor control module 124. When a fault is present, the motor control module 124 can disconnect the power to the electric motor 120 (disable the electric motor 120) and stop the stamping and vertical movement of one or more parts of the die.
[0101] The preceding description is illustrative in nature and is in no way intended to limit this disclosure, its application, or use. The broad teachings of this disclosure can be implemented in many forms. Therefore, while this disclosure includes specific examples, its true scope should not be so limited, as other modifications will become apparent upon examination of the drawings, specification, and appended claims. It should be understood that one or more steps in the method may be performed in a different order (or simultaneously) without altering the principles of this disclosure. Furthermore, although each embodiment in these examples is described above as having certain features, any one or more of those features described with respect to any embodiment of this disclosure may be implemented in any embodiment of other embodiments and / or combined with features of any embodiment of other embodiments, even if such combination is not explicitly described. In other words, the described embodiments are not mutually exclusive, and the arrangement of one or more embodiments with respect to each other remains within the scope of this disclosure.
[0102] Spatial and functional relationships between components (e.g., between modules, circuit elements, semiconductor layers, etc.) are described using various terms, including “connected,” “joined,” “linked,” “adjacent,” “right next to,” “on top of,” “above,” “below,” and “set on.” Unless explicitly described as “direct,” when describing the relationship between a first component and a second component in the foregoing disclosure, the relationship can be a direct relationship in which no other intermediate components exist between the first and second components, or it can be an indirect relationship in which one or more intermediate components (spatially or functionally) exist between the first and second components. As used herein, the phrase “at least one of A, B, and C” should be interpreted as using the non-exclusive logic “OR” to represent logic (A or B or C) and should not be interpreted as representing “at least one of A, at least one of B, and at least one of C.”
[0103] In the accompanying drawings, the direction of the arrowhead typically indicates the flow of information (such as data or instructions) of interest. For example, when component A and component B exchange various types of information, but the information transmitted from component A to component B is relevant to the illustration, the arrow may point from component A to component B. This unidirectional arrow does not imply that no other information is transmitted from component B to component A. Furthermore, for information sent from component A to component B, component B may send a request for the information to component A or receive an acknowledgment.
[0104] In this application, including the following definitions, the term "module" or "controller" may be replaced by the term "circuit". The term "module" may refer to, be a part of, or include: application-specific integrated circuit (ASIC); digital, analog, or mixed-signal analog / digital discrete circuit; digital, analog, or mixed-signal analog / digital integrated circuit; combinational logic circuit; field-programmable gate array (FPGA); processor circuitry (shared, dedicated, or grouped) that executes code; memory circuitry (shared, dedicated, or grouped) that stores code executed by the processor circuitry; other suitable hardware components that provide the described functionality; or some or all of the foregoing, such as in a system-on-a-chip.
[0105] A module may include one or more interface circuits. In some examples, the interface circuits may include wired or wireless interfaces connected to a local area network (LAN), the Internet, a wide area network (WAN), or a combination thereof. The functionality of any given module disclosed herein may be distributed across multiple modules connected via the interface circuits. For example, multiple modules may allow for load balancing. In another example, a server (also referred to as a remote or cloud) module may perform some functions on behalf of a client module.
[0106] As used above, the term "code" can include software, firmware, and / or microcode, and can refer to programs, routines, functions, classes, data structures, and / or objects. The term "shared processor circuitry" covers a single processor circuitry that executes some or all of the code from multiple modules. The term "group processor circuitry" covers processor circuitry combined with additional processor circuitry to execute some or all of the code from one or more modules. References to multiple processor circuitry cover multiple processor circuitry on a discrete die, multiple processor circuitry on a single die, multiple cores of a single processor circuitry, multiple threads of a single processor circuitry, or a combination thereof. The term "shared memory circuitry" covers a single memory circuitry that stores some or all of the code from multiple modules. The term "group processor circuitry" covers memory circuitry combined with additional memory to store some or all of the code from one or more modules.
[0107] The term "memory circuit" is a subset of the term "computer-readable medium." As used herein, the term "computer-readable medium" does not cover transient electrical or electromagnetic signals propagated through a medium (such as a carrier wave); therefore, the term "computer-readable medium" can be considered tangible and non-transient. Non-limiting examples of non-transient tangible computer-readable media are non-volatile memory circuits (such as flash memory circuits, erasable programmable read-only memory circuits, or mask read-only memory circuits), volatile memory circuits (such as static random access memory circuits or dynamic random access memory circuits), magnetic storage media (such as analog or digital magnetic tape or hard disk drives), and optical storage media (such as CDs, DVDs, or Blu-ray discs).
[0108] The apparatus and methods described in this application can be implemented, in part or in whole, by a special-purpose computer created by configuring a general-purpose computer to perform one or more specific functions embodied in a computer program. The function blocks, flowchart components, and other elements described above serve as software specifications that can be translated into computer programs through the routine work of skilled technicians or programmers.
[0109] A computer program includes processor-executable instructions stored on at least one non-transitory, tangible, computer-readable medium.
