Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to an automated mechanism for workpiece flipping. Background Technology

[0002] In the automotive parts manufacturing industry, it's common to encounter situations where the workpiece's center of gravity is shifted to one side, but processing takes place on the other. To maintain stability during clamping, the center of gravity needs to be kept low during transport. This situation is inconvenient for subsequent processing. Many machining centers use a secondary flipping mechanism to flip the workpiece individually, but this is complex, prone to jamming, and susceptible to tilting during the secondary flip. Therefore, it's necessary to pre-position the workpiece on one side before processing, and then clamp multiple workpieces simultaneously for processing. This necessitates an automated mechanism for automatic loading detection, unloading positioning, and automatic unloading, making the solution to this problem crucial. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide an automated mechanism for workpiece flipping, which solves the problems in the background art.

[0004] To achieve the above objectives, the present invention provides an automated mechanism for workpiece flipping, comprising a processing machine and a workpiece to be processed. The workpiece includes an A-side and a B-side arranged opposite each other. An arc surface A is provided on one side of the A-side, and an arc surface B is provided on one side of the B-side. A feeding conveyor is provided on the left side of one side of the processing machine, and a discharging conveyor is provided on the right side of one side of the processing machine. A vision mechanism is provided on one side of the end of the feeding conveyor, and a feeding positioning mechanism is provided on the other side of the end of the feeding conveyor. The feeding positioning mechanism and the discharging conveyor are arranged opposite each other. A robotic arm picking and unloading mechanism is provided between the feeding positioning mechanism and the discharging conveyor. Workpieces transported on the feeding conveyor line with their A side facing down are visually identified at the end by a vision mechanism. The robotic arm pick-and-place mechanism clamps the arc surface B of the workpiece's B side and transfers it to the unloading positioning mechanism. The unloading positioning mechanism places four workpieces, and the robotic arm pick-and-place mechanism simultaneously clamps the arc surface A of the four workpieces' A side and transfers them into the processing machine for processing. After processing, the robotic arm pick-and-place mechanism simultaneously clamps the four workpieces, blows air on them, and then transfers them to the unloading conveyor line.

[0005] Preferably, the feeding conveyor line includes a conveyor body, a guardrail is provided on the side of the conveyor body, a clamping cylinder is movably provided on the side of the end of the conveyor body, a clamping component is movably connected to the output end of the clamping cylinder, both ends of the clamping cylinder are movably connected to the side of the conveyor body, the clamping component extends with an extension arm and is movably connected to the side of the conveyor body, and the clamping component moves in an arc with the connection point between the extension arm and the side of the conveyor body as the center.

[0006] Preferably, the vision mechanism includes a vision bracket disposed at the end of the conveyor line, a display disposed on one side of the vision bracket, a longitudinal slide rail disposed on the inner wall of the vision bracket, a vision cylinder disposed at the bottom of the vision bracket, a vision mounting plate fixedly connected to the top output end of the vision cylinder, the vision mounting plate slidingly connected to the slide rail, and a camera disposed on the lower surface of the vision mounting plate, the camera being located above the clamping part.

[0007] Preferably, the feeding conveyor line includes a feeding conveyor line body, a sampling frame is provided on the side of the feeding conveyor line body, a sampling plate is provided at the top of the sampling frame extending above the feeding conveyor line body, a baffle is provided on the surface of the sampling plate, optical shafts are provided on both sides inside the sampling plate, and a sliding handle is provided on the surface of the two optical shafts, with the sliding handle and the baffle being arranged opposite to each other.

[0008] Preferably, the material feeding and positioning mechanism includes a material feeding frame, a positioning top plate on the top of the material feeding frame, and a spaced-apart card plate 1 and card plate 2 on the top of the positioning top plate. Card plate 1 has card slot 1 distributed on its top, and card plate 2 has card slot 2 distributed on its top. Card slot 1 and card slot 2 are arranged opposite to each other and combined together to place the workpiece.

[0009] Preferably, the arc surface A is secured to one side of the first slot, and the arc surface B is secured to one side of the second slot.

[0010] Preferably, an oil receiving tray is provided outside the middle part of the feeding rack.

[0011] Preferably, the robotic arm material handling mechanism includes a robotic arm base, a six-axis robotic arm is mounted on the top of the robotic arm base, and a material handling module is mounted at the end of the six-axis robotic arm.

[0012] Preferably, the material handling module includes an L-shaped connecting seat connected to the end of a six-axis robotic arm. One end of the L-shaped connecting seat is provided with a mounting plate. On the side of the mounting plate away from the L-shaped connecting seat, four three-jaw cylinders are provided for simultaneously clamping the arc surface A of the A side of four workpieces. An auxiliary plate is provided on the side of the mounting plate, and a three-jaw cylinder is provided on the side of the auxiliary plate for clamping the arc surface B of the B side of the workpiece.

[0013] Preferably, the mounting plate is provided with four corresponding three-jaw cylinder air blowing pipes at one end near the L-shaped connecting seat.

[0014] The beneficial effects of this invention are: Significantly improves processing efficiency and adapts to mass production: Through the material storage mode of "single-piece transfer + four-piece synchronous processing", the robotic arm can first complete the flipping of four workpieces individually, and then complete the loading and unloading of four workpieces at once, avoiding the time loss of repetitive single-piece operations; at the same time, it integrates the entire process of loading, vision recognition, positioning, processing, chip removal and unloading into full automation, without the need for manual intervention in the transfer, significantly improving the production line cycle time and adapting to the needs of large-scale mass production.

[0015] Precise and stable positioning ensures processing quality: A dual guarantee mechanism of "visual recognition + mechanical slot positioning" is adopted. The front-end vision mechanism accurately determines the posture and position of the workpiece, while the rear-end feeding and positioning mechanism achieves neat arrangement and precise positioning of the workpiece by fitting and limiting the workpiece with the workpiece's arc surfaces A and B through slot one and slot two. The robotic arm is designed with a special clamping structure for the arc surfaces, which clamps firmly without damaging the workpiece surface, effectively avoiding processing misalignment, workpiece displacement and other problems, and ensuring the consistency of processing accuracy of surface A and surface B.

[0016] Functional integration simplifies equipment layout and operation: The functions of flipping, clamping, air blowing to remove chips, and sampling inspection are integrated into one unit. The robotic arm picking and placing module comes with an air blowing pipe, and the cleaning of iron chips and oil stains is completed simultaneously after processing, eliminating the need for a separate dust removal station; the unloading conveyor line integrates a sampling tray and a sliding positioning structure, eliminating the need for an additional quality inspection station, simplifying the overall equipment layout, reducing the complexity of the operation process, and reducing the labor intensity of manual handling and quality inspection.

[0017] Adaptable to irregularly shaped workpieces with strong versatility: Designed with exclusive positioning slots and clamping structures for irregularly shaped workpieces with curved surfaces A and B, the workpieces are precisely clamped by a three-jaw cylinder through the fitting and limiting of the curved surface with the slots, adapting to the flipping and processing requirements of such irregularly shaped workpieces; at the same time, the enclosure of the feeding conveyor line and the arc-shaped stop structure of the clamping parts can effectively prevent the workpiece from shifting during the conveying process, further improving the adaptability and stability of irregularly shaped workpieces.

[0018] Reduce labor costs and human error: Fully automated operation reduces manual intervention and avoids inefficiencies and operational errors caused by manual flipping and material handling; no manual workpiece posture correction or transfer is required, reducing processing errors and workpiece damage risks caused by human factors, while reducing labor input costs and improving the safety and stability of the production process.

[0019] The equipment operates cleanly and conveniently with low maintenance costs: the feeding and positioning mechanism is equipped with an oil receiving tray, which can collect oil and debris dripping during processing, keeping the equipment and working environment clean; the structure of each mechanism is simple, and key components such as the feeding line card and the vision mechanism camera are easy to adjust, such as the vision cylinder driving the camera to lift and lower, which reduces the difficulty of subsequent maintenance and repair, and lowers the maintenance costs of long-term operation of the equipment.

After processing, the robotic arm picking and placing mechanism 100 simultaneously clamps the four workpieces 600, blows air on them, and then transfers them to the unloading conveyor line 500. Integrating the entire process of material feeding and conveying, visual inspection, positioning and temporary storage, robotic arm picking and flipping, machine tool processing, air blowing cleaning, and unloading and conveying, the robotic arm can first complete the flipping of four workpieces individually, and then complete the loading and unloading of four workpieces at once, avoiding the time loss of repetitive single-piece operations.
