Description

Technical Field

[0001] This utility model relates to the field of stamping equipment for automotive parts, and in particular to a multi-station, multi-axis, single-arm robotic arm for stamping automotive parts. Background Technology

[0002] Metal transfer die stamping is a processing technology widely used in the automotive parts manufacturing industry. It mainly uses a multi-station die system to achieve continuous forming and transfer of metal sheets. Specifically, this process uses a transfer die to sequentially transfer raw materials between multiple stamping stations. Each station performs a specific stamping operation, such as stretching, trimming, or bending, thereby efficiently producing complex metal parts, such as automotive body parts or structural components.

[0003] Related technologies propose a stamping equipment for automotive parts. In this equipment, product handling during the metal transfer die stamping process typically relies on a single robotic arm. This robotic arm can only grasp and place a single product at a time, achieving a single transfer from one workstation to the next. While this single-arm, single-operation mode can basically meet basic handling needs, it cannot handle multiple products simultaneously or allow multiple workstations to operate concurrently.

[0004] Therefore, this single-product pick-and-place mode in related technologies suffers from significant inefficiency. Since each handling operation is limited to only one product, the overall production cycle time is prolonged, especially in high-volume production lines. This can easily lead to increased mold idle time, thereby reducing the utilization rate of stamping equipment and overall capacity. Utility Model Content

[0006] To achieve the above objectives, this utility model proposes a multi-station, multi-axis, single-arm robot for stamping automotive parts, applied to stamping equipment for automotive parts.

[0009] In some embodiments, the first mating structure is a latch provided on the base, and the second mating structure is provided with a latching block that can extend into the latch, wherein the latch and the latching block engage in a latching fit.

[0010] In some embodiments, the locking member further includes a rotating unlocking component, which includes a rotating block and a handle. One end of the rotating block is rotatably disposed on the base, and the other end is provided with the latch. The handle is connected to the rotating block and is used to be driven by an external force to rotate the rotating block so that the latch engages or disengages with the latch.

[0011] In some embodiments, the adapter is cylindrical and at least partially slidably inserted into the first mounting cavity; the second mating structure is disposed on the outer surface of the adapter; and a receiving notch is provided on the side wall of the first mounting cavity for the locking block to slidably extend into; and / or The adapter is hollow and has a second mounting cavity, which is used to mount the material taking component.

[0012] In some embodiments, the transfer drive mechanism includes: A translation drive is disposed on the base, and the conveying mechanism is disposed at the output end of the translation drive. The translation drive is used to drive the conveying mechanism to move horizontally along the length direction of the base.

[0013] In some embodiments, the transfer drive mechanism further includes: A first lifting drive is disposed on the base and located on the upper side of the mold. A translation drive is disposed at the output end of the first lifting drive.

Secondly, it enhances flexibility and adaptability: the quick-release base design allows for rapid disassembly and replacement of parts, facilitating adjustments for the shape, size, or material of different automotive parts (such as body panels or structural components), reducing equipment maintenance costs and downtime.

[0022] This application relates to a multi-station, multi-axis, single-arm robotic arm for stamping automotive parts. The stamping equipment includes a base and a die mounted on the base. The die is used to carry multiple products spaced apart, which are automotive parts.

[0023] Reference Figures 1 to 3 In a preferred embodiment, the multi-station, multi-axis, single-arm robot for stamping automotive parts proposed in this application, mounted on a base, includes: Transfer drive mechanism 1 is mounted on the machine base; The conveying mechanism 2 is spaced apart from the mold and includes a mounting base 21 disposed at the output end of the transfer drive mechanism 1, a plurality of quick-release seats 22 disposed on the mounting base 21, and a plurality of picking parts disposed corresponding to each quick-release seat 22, each picking part being detachably disposed on a quick-release seat 22. The transfer drive mechanism 1 is used to drive the mounting base 21 to move the picking component in the direction toward or away from the mold, and the picking component is used to pick up and put down the product.

[0024] In this embodiment, the main working principle of the multi-station multi-axis single-arm robot for stamping automotive parts is based on the coordinated operation of the transfer drive mechanism 1 and the handling mechanism 2, which realizes the synchronous picking, placing and transferring of multiple automotive parts in the multi-station mold. Specifically, the transfer drive mechanism 1 is installed on the base of the stamping equipment and serves as the power source and motion control core. It can drive the mounting base 21 to move along a preset path through multi-axis linkage (exemplary, such as X, Y, and Z axis modules). For example, it can include approaching the mold and retracting away from the mold, lateral movement between multiple products, and lifting or lowering movement towards or away from the product in the vertical direction.

[0025] The conveying mechanism 2 is spaced apart from the mold. Its mounting base 21 is fixed to the output end of the transfer drive mechanism 1 and is equipped with multiple quick-release seats 22. Each quick-release seat 22 corresponds to a detachable material-grabbing component (such as a vacuum suction cup, mechanical gripper, or magnetic adsorbent). For example, the quick-release seat 22 can be an end effector. An end effector (usually referring to an "end effector") is a device used by a robot arm or industrial robot end to perform a specific task. It can be designed according to application requirements and can be a tool with functions such as gripping, holding, welding, grinding, or assembly. In this application, it is preferred to set the material-grabbing component as a gripping or holding tool, such as a suction cup or gripper.

[0026] During operation, the transfer drive mechanism 1 first drives the mounting base 21 to carry multiple picking parts close to the mold position. This movement can be along the length, width, and vertical directions of the base. Subsequently, each picking part is activated independently or simultaneously to precisely pick up multiple automotive parts spaced apart on the mold. After picking is completed, the transfer drive mechanism 1 reverses and drives the mounting base 21 back, transferring the product to the next workstation or a designated location for placement. This parallel design of multiple picking parts, combined with a quick-release mechanism, ensures that the robot can achieve synchronous operation at multiple workstations under a single-arm structure, while allowing for quick replacement of picking parts to adapt to different part specifications.

[0027] This application achieves the following beneficial effects in the stamping production of automotive parts by configuring a robotic arm with the aforementioned structure. Firstly, it improves production efficiency: by using a parallel pick-and-place mode for multiple parts, it processes multiple products spaced at intervals at once, avoiding the inefficiency of traditional single-arm robotic arms that pick and place one part at a time. This significantly shortens the product transfer cycle, reduces mold idle time, and thus improves the overall capacity and utilization rate of the stamping equipment. Secondly, it enhances flexibility and adaptability: the quick-release seat 22 design allows for rapid disassembly and replacement of parts, facilitating adjustments for the shape, size, or material of different automotive parts (such as body panels or structural components). This reduces equipment maintenance costs and downtime, supporting flexible production of multiple varieties in small batches. Furthermore, this robotic arm promotes automation, reduces the need for human intervention, lowers operational risks and labor costs, and ensures the stability and accuracy of the pick-and-place process through precise multi-axis control, avoiding product damage or positioning errors. Ultimately, it achieves continuous, efficient, and reliable operation of the stamping process.

[0028] Reference Figures 1 to 3 In some embodiments, the quick-release seat 22 proposed in this application includes: The base 221 is detachably mounted on the mounting base 21 and has a first mounting cavity 2210 for mounting the material handling component; Locking member 222, at least partially disposed on base 221, is used to configure the picking member and base 221 as follows: The material being picked up and the base 221 are in a fixed state of relative motion; or The material pick-up component and the base 221 are in a state of relative mobility.

[0029] In this embodiment, the quick-release base 22 operates based on the mechanical cooperation mechanism between the base 221 and the locking component 222, enabling the rapid installation and removal of the material on the mounting base 21. This ensures the high efficiency and ease of maintenance of the robot during the stamping process of automotive parts. Specifically, the base 221, as the carrier of the quick-release base 22, is detachably fixed to the mounting base 21 of the conveying mechanism 2. The first mounting cavity 2210 inside is designed as a standardized accommodating space for receiving and initially positioning the material (such as a vacuum suction cup or gripper), providing a mechanical interface to support the insertion and alignment of the material.

[0030] The locking component 222 is at least partially integrated into the structure of the base 221, and is typically driven by mechanical, hydraulic, or electromagnetic means (e.g., pin, snap, or bolt mechanisms). Its function is to control the relative degrees of freedom of movement between the material pick-up component and the base 221 through state switching. In the locking mode, the locking component 222 is activated and applies a constraint force, so that the picking component and the seat 221 form a rigid connection and are in a state of immobility. This ensures that the picking component can stably grab and transport multiple spaced automotive parts during high-speed stamping and transfer, and avoids product drop or positioning errors caused by vibration or displacement. In the unlocked mode, the locking component 222 releases its constraint, allowing the material picker and the base 221 to be in a relatively movable state, which makes it easy for operators to quickly pull out or replace the material picker to meet the needs of different parts specifications, shapes or materials.

[0031] Reference Figures 1 to 3 In some embodiments, the multi-station multi-axis single-arm robot for stamping automotive parts proposed in this application also includes a converter 223, which is extendably disposed in the first mounting cavity 2210 and is used to install the material handling component. The locking component 222 includes a first mating structure 2221 and a second mating structure 2222. The first mating structure 2221 is disposed on the base 221, and the second mating structure 2222 is disposed on the adapter 223. The first mating structure 2221 and the second mating structure 2222 are detachably connected so that the base 221 and the adapter 223 are detachably connected.

[0032] In this embodiment, the working principle of the adapter 223 and the locking component 222 is based on the collaborative design of the modular connection mechanism, realizing the rapid and reliable installation and removal of the picking component on the quick-release seat 22, thereby enhancing the adaptability and maintenance efficiency of the robot in the stamping process of automotive parts. Specifically, the adapter 223, as an intermediate adapter component, can be inserted into the first mounting cavity 2210 of the seat 221. One end of the adapter 223 fixes the picking component (such as a vacuum suction cup or gripper), and the other end is designed as a standardized interface, which is convenient for insertion into the cavity and initial alignment and positioning. This inserted structure ensures that the adapter 223 and the seat 221 form a tight fit, providing mechanical support and force transmission path, while allowing the picking component to be customized according to the specifications (such as shape, size or material) of different automotive parts without directly modifying the structure of the seat 221. The locking component 222 achieves a controllable connection through the complementary design of the first mating structure 2221 and the second mating structure 2222: the first mating structure 2221 is fixed to the base 221 (such as a slot, pin hole, or threaded interface), and the second mating structure 2222 is correspondingly set on the adapter 223 (such as a buckle, pin, or matching thread). The two are detachably connected by mechanical, hydraulic, or electromagnetic means. In the connected state, the first and second mating structures 2222 are locked to each other, forming a rigid constraint, so that the base 221 and the adapter 223 are in a state where they cannot move relative to each other, ensuring that the picking component remains stable when simultaneously grabbing and transporting multiple spaced products at multiple workstations, and avoiding detachment caused by vibration or displacement. In the disassembled state, the mating structure is released, so that the adapter 223 can be easily pulled out of the cavity, which is convenient for quick replacement of the picking component or maintenance.

[0033] Reference Figures 1 to 3 In some embodiments, the first mating structure 2221 proposed in this application is a bayonet provided on the base 221, and the second mating structure 2222 is a card block that can extend into the bayonet, with the bayonet and the card block engaging.

[0034] In this embodiment, the working principle of the bayonet and the locking block is based on the mechanical locking mechanism of the snap-fit ​​engagement, realizing a quick and reversible connection between the first mating structure 2221 and the second mating structure 2222 of the locking component 222, thereby ensuring the stable installation and convenient disassembly of the adapter 223 and the seat 221 in the automotive parts stamping robot. Specifically, the first mating structure 2221 is designed as a bayonet set in the seat 221, usually a groove, notch, or guide groove structure, providing an insertion path and positioning reference; the second mating structure 2222 is a locking block that can extend into the bayonet, usually a protrusion, pin, or hook-shaped component, matching the shape and size of the bayonet. During the connection process, the locking block carried by the adapter 223 extends into the bayonet of the seat 221 along a preset direction, and achieves locking engagement through relative sliding, rotation, or pressing actions: After the locking block is embedded in the bayonet, it forms an interlocking state using geometric constraints (such as barbs, inclined planes, or spring assistance), making the seat 221 and the adapter 223 rigidly connected and unable to move relative to each other. This provides sufficient tensile, shear, and stability when simultaneously grabbing and transporting multiple spaced automotive parts at multiple workstations, preventing them from falling off due to vibration or impact. During the disassembly process, the locking constraint is released by applying a reverse force (such as pulling, rotating, or releasing the button), and the locking block exits from the bayonet, allowing the seat 221 and the adapter 223 to return to a state where they can move relative to each other, facilitating quick replacement of the picking parts to adapt to different part specifications.

[0035] Reference Figures 1 to 3 In some embodiments, the locking member 222 proposed in this application further includes a rotating unlocking member 2223. The rotating unlocking member 2223 includes a rotating block 2223A and a handle 2223B. One end of the rotating block 2223A is rotatably disposed on the base 221, and the other end is provided with a latch. The handle 2223B is connected to the rotating block 2223A and is used to be driven by external force to drive the rotating block 2223A to rotate, so that the latch can engage or disengage with the latch.

[0036] In this embodiment, the working principle of the rotating unlocking component 2223 is based on the mechanical linkage mechanism of lever rotation and snap-fit ​​switching, realizing the manual and controllable adjustment of the connection state between the locking component 222 and the base 221, thereby facilitating the rapid installation and disassembly of the material handling parts in the automotive parts stamping robot. Specifically, the rotating unlocking component 2223 consists of a rotating block 2223A and a handle 2223B. One end of the rotating block 2223A is rotatably fixed to the base 221 by a hinge, pin, or other rotary joint, providing rotational freedom as a fulcrum. The other end of the rotating block 2223A has a slot, serving as the first mating structure 2221, for receiving the insertion and locking of the snap-fit ​​block. The handle 2223B is fixedly connected to the rotating block 2223A and is usually designed as an extension rod or grip, making it convenient for the operator to apply external force (such as manual pulling or pushing) to drive the rotating block 2223A to rotate around the fulcrum. During the locking process, external force drives the rotating block 2223A to rotate clockwise or counterclockwise through the handle 2223B, so that the latch aligns with and embeds into the latch on the adapter 223. Through geometric matching (such as the interlocking inclined surface of the hook-shaped latch and the latch), a latching engagement state is formed, ensuring that the seat 221 and the adapter 223 are rigidly connected and cannot move relative to each other. This provides stable mechanical constraints when multiple workstations simultaneously grab and transport multiple spaced automotive parts, avoiding detachment caused by vibration or impact. During the unlocking process, external force is applied in the opposite direction to drive the rotating block 2223A to rotate, the latch separates from the latch, releases the constraint, and restores the seat 221 and the adapter 223 to a state where they can move relative to each other, facilitating the extraction and replacement of the adapter 223 (and the picking part).

[0037] Reference Figures 1 to 3 In some embodiments, the adapter 223 proposed in this application is cylindrical and at least partially slidably passes through the first mounting cavity 2210. The second mating structure 2222 is disposed on the outer surface of the adapter 223. The side wall of the first mounting cavity 2210 has an accommodating notch 2211 for the slidable insertion of the locking block; and / or The adapter 223 has a hollow cavity forming a second mounting cavity 2230, which is used to mount the material picking component.

[0038] In this embodiment, the working principle of the adapter 223 is based on the combination of cylindrical sliding fit and snap-fit ​​positioning mechanism, so as to realize the precise and rapid installation and disassembly of the material picking part on the quick-release seat 22, thereby optimizing the adaptability and operating efficiency of the automotive parts stamping robot in multi-station operation. Specifically, the adapter 223 is designed as a cylindrical structure, providing rotational symmetry and guidance. It is at least partially slidably inserted into the first mounting cavity 2210 of the base 221. By sliding insertion, the adapter 223 smoothly enters the cavity axially. The smoothness of the cylindrical outer surface reduces frictional resistance, ensuring smooth insertion and alignment accuracy. The second mating structure 2222 (such as a locking block) is provided on the outer surface of the adapter 223. It is usually a protrusion or hook-shaped component. During insertion, it can slide into the cavity through the receiving notch 2211 on the side wall of the first mounting cavity 2210. This notch serves as a guide channel and limiting structure, allowing the locking block to be accurately positioned and to form a locking engagement with the first mating structure 2221 (such as a bayonet) of the locking member 222. This provides radial and axial constraints in the connected state, making the adapter 223 rigidly fixed to the base 221, and preventing it from falling off due to vibration or displacement during the stamping transfer process. Meanwhile, the hollow interior of the adapter 223 forms a second mounting cavity 2230, which serves as a dedicated mounting space for the material picking component. This cavity can be used to fix the material picking component (such as a vacuum suction cup or gripper) by means of threads, snaps, or press fitting, thereby realizing the modular integration of the material picking component and facilitating customized installation according to different automotive parts specifications.

[0039] Reference Figures 1 to 3 In some embodiments, the transfer drive mechanism 1 proposed in this application includes: Translation drive 11 is mounted on the base, and conveying mechanism 2 is mounted on the output end of translation drive 11. Translation drive 11 is used to drive conveying mechanism 2 to move horizontally along the length of the base.

[0040] In this embodiment, the working principle of the translation drive 11 is based on the power output and control of the linear transmission mechanism, realizing the precise horizontal displacement of the conveying mechanism 2 on the stamping equipment base, thereby supporting multi-station synchronous operation of the automotive parts stamping robot. Specifically, the translation drive 11 can be directly or indirectly set on the base, serving as the core power component of the transfer drive mechanism 1. It typically adopts a drive form such as a servo motor, hydraulic cylinder, pneumatic cylinder, or lead screw guide rail, and its output end is connected to the conveying mechanism 2 (e.g., through a coupling or slider interface). During operation, the translation drive 11 receives control signals (such as PLC or CNC system instructions) to activate the internal power source, generating linear thrust or torque, which is converted into horizontal movement of the conveying mechanism 2 through transmission elements (such as guide rails, chains, or racks), allowing for controllable forward or backward movement along the length of the base.

[0041] Reference Figures 1 to 3 In some embodiments, the transfer drive mechanism 1 proposed in this application further includes: The first lifting drive 12 is disposed on the base and located on the upper side of the mold. The translation drive 11 is disposed at the output end of the first lifting drive 12. The first lifting drive 12 is used to drive the translation drive 11 to move, so as to drive the conveying mechanism 2 to move towards or away from the mold in the vertical direction.

[0042] In this embodiment, the working principle of the first lifting drive component 12 is based on the power output and control of the vertical linear transmission mechanism, realizing the precise vertical displacement of the translation drive component 11 and the conveying mechanism 2 on the stamping equipment base, thereby supporting the lifting coordination of the automotive parts stamping robot in multi-station operations. Specifically, the first lifting drive component 12 is fixedly installed on the base and located on the upper side of the mold. As the upper power component of the transfer drive mechanism 1, it is usually in the form of hydraulic cylinder, air cylinder, servo motor driven screw or rack guide, etc., and its output end is directly connected to the translation drive component 11 (such as through a flange or bracket interface). During operation, the first lifting drive component 12 receives control signals (such as PLC or sensor feedback) to activate the internal power source, generating vertical thrust or torque, and converts the power into the vertical movement of the translation drive component 11 through transmission elements (such as guide columns, chains or lifting frames), driving the conveying mechanism 2 to descend towards the mold or rise away from the mold in the vertical direction. The motion path is designed as a straight line to ensure that the multiple picking parts carried by the conveying mechanism 2 are accurately lowered to the mold height before being gripped, so as to approach and adsorb multiple automotive parts that are spaced apart; after placement or transfer, it rises in the opposite direction to avoid interfering with the mold operation.

[0043] Reference Figures 1 to 3 In some embodiments, the transfer drive mechanism 1 proposed in this application further includes: A transverse drive 13 is mounted on the base, and a first lifting drive 12 is mounted on the output end of the transverse drive 13. The transverse drive 13 is used to drive the conveying mechanism 2 to move horizontally along the width direction of the base.

[0044] In this embodiment, the transverse drive 13 is used to drive the conveying mechanism 2 to move horizontally along the width direction of the base. Specifically, it changes the horizontal position of the picking component relative to the mold. For example, the first picking component was originally aligned with the first product in the mold. After the transverse drive 13 drives the conveying mechanism 2 to move, the first picking component is aligned with the second product in the mold, and so on.

[0045] The transverse drive component 13 is used to link with the other drive components, enriching the drive path of the conveying mechanism 2, thereby realizing multi-directional drive of the conveying mechanism 2.

[0046] Reference Figures 1 to 3In some embodiments, the transfer drive mechanism 1 proposed in this application further includes: The lifting mechanism 14 is mounted on the machine base. The transverse drive component 13 is mounted on the output end of the lifting mechanism 14 via the mounting bracket 5. The lifting mechanism 14 is used to drive the conveying mechanism 2 to move vertically toward or away from the mold. The lifting mechanism 14 includes two second lifting drive components 141 spaced apart, and the mounting bracket 5 is mounted between the two second lifting drive components 141.

[0047] In this embodiment, the function of the second lifting drive 141 is the same as that of the first lifting drive 12. Its function is to increase the vertical movement stroke of the conveying mechanism 2 relative to the machine base. For example, the first lifting drive 12 is used to drive the conveying mechanism 2 to move a small displacement so that the picking part contacts or moves away from the product, while the second lifting drive 141 is used to drive the conveying mechanism 2 to move a larger displacement so that the conveying mechanism 2 moves closer to or away from the mold in the vertical direction between different workstations and devices.
