Description

Technical Field

[0001] This application relates to the technical field of parts processing, and in particular to a flipping device for flipping stamped parts. Background Technology

[0002] In the current field of parts processing technology, the processing of stamped parts often involves multiple steps, among which the flipping process is a common and crucial one. Traditional methods of flipping stamped parts mostly rely on manual operation, which is not only inefficient and labor-intensive, but also prone to damage or displacement of parts during the flipping process due to human factors, thus affecting the subsequent processing accuracy and product quality.

[0003] With the continuous development of automation technology, some flipping equipment for turning over stamped parts has emerged on the market. These devices are operated by using robotic arms, which use the gripping motion of the robotic arms and the rotation of the equipment to turn over the parts, avoiding manual handling. However, some devices have poor compatibility with parts during the flipping process and cannot adapt to the flipping requirements of stamped parts of different shapes and sizes, resulting in significant limitations in practical applications. In addition, some devices lack stability during operation and are prone to failure, affecting production progress and efficiency.

[0004] Therefore, developing a flipping device to solve the technical problems of poor compatibility and insufficient stability of existing equipment has become an urgent problem to be solved in the field of parts processing technology. Summary of the Invention

[0005] To address the technical problems of poor compatibility and insufficient stability of existing flipping equipment, this application provides a flipping device for flipping stamped parts.

[0006] A flipping device for flipping stamped parts includes a frame and a flipping execution mechanism disposed on the top of the frame. The flipping execution mechanism includes a drive shaft, rotating seats disposed at both ends of the drive shaft and rotatably connected to the drive shaft, a rotation drive mechanism for driving the drive shaft, and an execution assembly fixed to the drive shaft. The execution assembly is provided with a first clamping assembly and a second clamping assembly for clamping the stamped parts. The top of the frame is also provided with a support platform for supporting the stamped parts after they have been flipped.

[0007] By employing the above technical solution, the flipping execution mechanism is located at the top of the frame. Driven by a drive mechanism, the drive shaft rotates, further actuating the execution components fixed to the drive shaft. This causes the first clamping component and / or the second clamping component on the execution components to clamp the stamped parts for flipping. Simultaneously, a support platform is set at the top of the frame to support the flipped stamped parts. This allows for efficient and stable flipping of the stamped parts. Furthermore, through the synergistic effect of the dual clamping components, this device can adapt to stamped parts of different sizes and shapes while ensuring the stability of the parts during the flipping process. This effectively avoids the problems of parts easily falling off and shifting position in traditional flipping methods, significantly improving the automation level and production efficiency of the flipping process. It provides a reliable guarantee for the accurate execution of subsequent processing steps and solves the problems of poor compatibility and insufficient stability of existing equipment.

[0008] Furthermore, the first clamp assembly is fixedly connected to the drive shaft via at least one connector. One end of the connector extends with a sliding rod. The rotating seat is provided with an arc-shaped slide rail adapted to the sliding rod. The end of the sliding rod is slidably disposed within the arc-shaped slide rail. The curvature of the arc-shaped slide rail is configured to restrict and guide the first clamp assembly to perform a 180° rotational movement around the axis of the drive shaft.

[0009] By adopting the above technical solution, during the flipping process, the movement trajectory of the first clamping assembly is achieved through the cooperation of the sliding rod and the arc-shaped slide rail, allowing the end of the sliding rod to slide within the arc-shaped slide rail. The design of the arc-shaped slide rail enables the first clamping assembly to precisely perform a 180° flipping motion around the axis of the drive shaft during the flipping process. The arc-shaped slide rail avoids unstable situations such as shaking and offset that may occur during the flipping process, further ensuring the stability and accuracy of the stamped parts during the flipping operation. This, in turn, improves the reliability and flipping efficiency of the entire flipping device, ensuring that the stamped parts can successfully complete the flipping process and meet the requirements of the production process.

[0010] Furthermore, the first clamping assembly includes a plurality of vacuum suction cups symmetrically arranged on both sides of the actuation assembly, and the second clamping assembly includes a plurality of mechanical grippers symmetrically arranged on both sides of the actuation assembly.

[0011] By adopting the above technical solution, the first clamping component is designed as a vacuum suction cup, which can stably adsorb flat stamped parts using the principle of vacuum adsorption. It is especially suitable for thin and flat parts, with uniform adsorption force and no mechanical damage to the surface of the parts. The mechanical jaws symmetrically arranged on both sides of the execution component hold the parts by mechanical clamping, which is more suitable for stamped parts with three-dimensional structures or higher heights, such as rolled parts. The mechanical jaws on both sides can open and close synchronously to ensure that the parts remain balanced during the flipping process. This dual clamping component design allows the device to flexibly adapt to the flipping requirements of stamped parts with different materials, weights and shapes. It not only solves the problem of poor adaptability of a single clamping method to the type of parts, but also ensures that the parts will not slip or shift during the flipping process. This synergistic design greatly improves the flipping effect and efficiency of the flipping process.

[0012] Furthermore, the bottom of the flipping actuator is provided with a lifting base, the rotating seat is fixedly installed on the lifting base, a fixed plate is provided at the bottom of the frame, and a lifting drive device is provided on the fixed plate. The output end of the lifting drive device is connected to the bottom of the lifting base and is used to directly drive the lifting base to perform vertical lifting movement.

[0013] By adopting the above technical solution, a lifting base is set at the bottom of the flipping actuator. The lifting drive device on the fixed plate inside the frame drives it to move vertically, flexibly adjusting the height of the flipping actuator and further adjusting the height of the actuator components. In actual use, the height position of the flipping actuator can be precisely adjusted according to the size of different stamped parts and flipping requirements, ensuring that the first and second clamping components are not affected by the size of the stamped parts, thus realizing the flipping operation. This further avoids the possibility of interference with the support platform or frame structure during the flipping process, which could lead to the inability to complete the 180-degree rotation or even jamming and damage. This not only improves the device's adaptability to different parts but also makes the flipping operation more precise, efficient, and stable, further enhancing the practicality and reliability of the device.

[0014] Furthermore, the lifting base is provided with at least two downward-extending guide rods, and the fixed plate at the bottom of the frame is provided with bushings that correspond one-to-one with the guide rods and slide in cooperation with them. The guide rods can be slidably inserted into the bushings. The lifting drive device is fixed on the fixed plate, and the output end of the lifting drive device is connected to the center of the bottom of the lifting base. The lifting drive device is a cylinder, a servo electric cylinder, or a hydraulic cylinder.

[0015] By adopting the above technical solution, a guide rod is set on the lifting base, and a bushing that slides with the guide rod is set on the fixed plate at the bottom of the frame. The guide rod slides up and down in the bushing. This design provides precise guidance for the vertical lifting movement of the lifting base, ensuring that the lifting base remains stable during the lifting process without deviation or shaking, thereby ensuring the stability and accuracy of the flipping actuator when adjusting the height. At the same time, the lifting drive device is fixed on the fixed plate, and its output end is connected to the center of the bottom of the lifting base. This layout allows the lifting drive device to apply force evenly, further improving the stability of the lifting base movement.

[0016] In addition, the lifting drive device uses a pneumatic cylinder, servo electric cylinder or hydraulic cylinder, which can realize precise height adjustment of the flipping device, ensure the smooth operation of flipping, and enhance the versatility and adaptability of the device.

[0017] Furthermore, the rotary drive mechanism includes a linear driver, a rack that is driven by the linear driver to reciprocate axially, and a gear that meshes with the rack and is fixed on the drive shaft. The linear driver is mounted on the lifting base.

[0018] By adopting the above technical solution, the rotary drive mechanism uses a linear actuator to drive the rack to reciprocate axially. The rack meshes with a gear fixed on the drive shaft, which converts linear motion into rotary motion, thereby driving the drive shaft to drive the actuator to perform a flipping action. Its structure is simple and reliable, with high transmission efficiency. It can accurately control the rotation angle and speed of the drive shaft, ensuring that the first and second clamping assemblies can complete the flipping operation of the stamped parts according to the preset trajectory and speed, effectively improving the working accuracy and stability of the flipping device. At the same time, by setting the linear actuator on the lifting base, the rotary drive mechanism can move vertically up and down with the lifting base, further enhancing the overall coordination and flexibility of the device, and better adapting to the flipping requirements of stamped parts of different sizes and shapes.

[0019] Furthermore, the lifting base is also provided with a linear slide rail, the bottom of the rack is slidably connected to the linear slide rail, and the linear driver drives the rack to slide back and forth on the linear slide rail.

[0020] By adopting the above technical solution, a linear slide rail is added to the lifting base, and the bottom of the rack is slidably connected to the linear slide rail. This design provides stable and precise guidance for the reciprocating motion of the rack, effectively reducing the friction and resistance of the rack during the movement, making the rack slide more smoothly, thereby improving the transmission efficiency and response speed of the entire rotary drive mechanism. At the same time, the linear actuator drives the rack to slide precisely back and forth on the linear slide rail, further ensuring the rotational accuracy and stability of the drive shaft, and providing more reliable power support for the flipping operation of stamped parts.

[0021] Furthermore, the linear actuator is a pneumatic cylinder, a servo electric cylinder, or a hydraulic cylinder.

[0022] By adopting the above technical solutions, the linear actuator can be a pneumatic cylinder, a servo electric cylinder, or a hydraulic cylinder to ensure that the rack can slide back and forth stably on the linear guide rail, thereby ensuring the reliable rotation of the drive shaft and realizing the flipping operation of the stamped parts.

[0023] Furthermore, the support platform is provided with multiple fixed guide rails, and at least one movable vacuum suction cup is provided on the fixed guide rails.

[0024] By adopting the above technical solution, multiple fixed guide rails are set on the support platform, and movable vacuum suction cups are configured on the fixed guide rails to ensure that the parts can be stably supported after flipping without damaging the surface of the parts. This is especially suitable for precision stamping parts with high surface requirements. In addition, the movable vacuum suction cups can be adapted to parts of various specifications, further improving the versatility and adaptability of the support platform and ensuring the efficient operation of the flipping device under different production needs.

[0025] Furthermore, a soft pad layer is provided on the top of the support platform, and the soft pad layer is provided with anti-slip texture.

[0026] By adopting the above technical solution, a soft pad layer is set on the top of the bearing platform. The soft pad layer can play a buffering and protective role, avoiding scratches or damage caused by direct contact between the stamped parts and the hard bearing platform after flipping. In addition, the anti-slip texture on the soft pad layer can increase the friction, prevent the stamped parts from sliding or shifting on the bearing platform, and ensure that the parts can be stably placed on the bearing platform after flipping, which provides convenience for subsequent processing steps and further improves the practicality and reliability of the device.

[0027] In summary, this application includes at least the following beneficial technical effects: (1) Through the synergistic effect of the dual clamping components, the device can flexibly adapt to the flipping requirements of stamped parts of different materials, weights and shapes. This not only solves the problem of poor adaptability of a single clamping method to part types, but also ensures that the parts will not slip or shift during the flipping process. This synergistic design greatly improves the flipping effect and efficiency of the flipping process, and effectively solves the problem of poor compatibility of traditional flipping devices. (2) The design of the lifting base and guide rod and bushing, as well as the transmission structure of the linear drive and rack and gear in the rotary drive mechanism, ensure the accuracy and stability of the flipping operation and avoid the shaking, displacement or damage of parts during the flipping process. (3) The bearing platform is equipped with a soft pad and anti-slip texture, which plays a role in buffering protection and anti-slip, further improving the practicality and reliability of the device.

[0030] The following combination Figure 1-4 The technical solutions in the embodiments of the present invention will be described in detail.

[0031] See Figure 1This invention provides a flipping device for flipping stamped parts, including a frame 1 and a flipping execution mechanism 2 disposed on the top of the frame 1. The flipping execution mechanism 2 includes a drive shaft 21, a rotating seat 22 disposed at both ends of the drive shaft 21 and rotatably connected to the drive shaft 21, a rotation drive mechanism 23 for driving the drive shaft 21, and an execution component 24 fixed to the drive shaft 21. The execution component 24 is provided with a first clamping assembly 241 and a second clamping assembly 242 for clamping the stamped parts. The top of the frame 1 is also provided with a support platform 3 for supporting the stamped parts after flipping.

[0032] Specifically, the first clamping assembly 241 consists of multiple vacuum suction cups symmetrically arranged on both sides of the execution assembly 24, and the second clamping assembly 242 includes multiple mechanical grippers symmetrically arranged on both sides of the execution assembly 24. When the stamped part is a plate-shaped or sheet-shaped planar part, the stamped part is transported and placed onto the first clamping assembly 241 by an external robot. The vacuum suction cups can adsorb the stamped part, and by rotating the drive shaft 21, the vacuum suction cups can rotate the stamped part 180 degrees to achieve flipping. When the stamped part is a part with a three-dimensional structure or a relatively high height, such as a rolled material, the stamped part... The part is transported and placed onto the first clamping assembly 241 or the plane of the execution assembly 24 by an external robotic arm. At this time, the mechanical jaws on both sides clamp the stamping part. By rotating the drive shaft 21, the first clamping assembly 241 and the second clamping assembly 242 can work together to rotate the stamping part 180 degrees to achieve flipping. The design of the dual clamping assembly not only solves the problem of poor adaptability of the single clamping method to the part type, but also ensures that the part will not slip or shift during the flipping process, which greatly improves the flipping effect and flipping efficiency of the flipping process and effectively solves the problem of poor compatibility of traditional flipping devices.

[0033] To ensure the stability of the rotating components, refer to Figure 2-3 The first clamping assembly 241 is fixedly connected to the drive shaft 21 via at least one connector 25. In this embodiment, two connectors 25 are provided, symmetrically arranged on the drive shaft 21. One end of the connector 25 extends to provide a sliding rod 251. The rotating seat 22 is provided with an arc-shaped slide rail 221 adapted to the sliding rod 251. The end of the sliding rod 251 is slidably disposed in the arc-shaped slide rail 221. The arc of the arc-shaped slide rail 221 is configured to restrict and guide the first clamping assembly 241 and the second clamping assembly 242 to perform a 180° flipping motion around the axis of the drive shaft 21. The sliding cooperation between the arc-shaped slide rail 221 and the sliding rod 251 effectively prevents the actuator from rotating excessively, further ensuring the operational stability of the flipping device.

[0035] Specifically, the lifting base 26 is provided with at least two downward-extending guide rods 261. The fixed plate 11 at the bottom of the frame 1 is provided with bushings 111 that correspond one-to-one with the guide rods 261 and slide in cooperation. The guide rods 261 can slide up and down in the bushings 111. The lifting drive device 12 is fixed on the fixed plate 11, and the output end of the lifting drive device 12 is connected to the center of the bottom of the lifting base 26.

[0036] As an optional implementation, the lifting drive device 12 can be any one of a pneumatic cylinder, a servo electric cylinder, or a hydraulic cylinder. In this embodiment, the lifting drive device 12 is a hydraulic cylinder.

[0037] To further ensure the accuracy and stability of the rotation of the actuator, the rotary drive mechanism 23 includes a linear driver 231, a rack 232 driven by the linear driver 231 to reciprocate axially, and a gear 233 meshing with the rack 232 and fixed on the drive shaft 21. The linear driver 231 is mounted on the lifting base 26.

[0038] To improve the stability of the rack 232's movement, a linear slide rail 234 is also provided on the lifting base 26. The bottom of the rack 232 is slidably connected to the linear slide rail 234, and the linear driver 231 drives the rack 232 to slide back and forth on the linear slide rail 234.

[0039] As an optional implementation, the linear actuator 231 can be any one of a pneumatic cylinder, a servo electric cylinder, or a hydraulic cylinder. In this embodiment, the linear actuator 231 is a pneumatic cylinder.

[0040] To ensure that the parts can be stably supported after being flipped, the support platform 3 is provided with multiple fixed guide rails 31, and at least one movable vacuum suction cup is provided on the fixed guide rail 31. The position of the vacuum suction cup can be adjusted on the fixed guide rail 31 according to the size of the parts.

[0041] To provide stability for the stamped parts after they are flipped over, a soft pad 32 is provided on the top of the support platform 3. The soft pad 32 is located between some of the fixed guide rails 31. The soft pad 32 is provided with anti-slip texture to reduce damage to the stamped parts and prevent the stamped parts from sliding or shifting on the support platform.
