Jinan Haozhong Automation Co., Ltd.

An external linear‑translation speed‑multiplier mechanism has been added to the flange of the robot’s sixth axis, enabling workpieces to be translated between presses in upstream and downstream operations. This eliminates the issues of complex trajectories and poor stability that previously arose from 180° rotations, while also facilitating a substantial increase in production throughput.
Simplifying the robot’s handling trajectory not only boosts production efficiency but also saves space—on large body‑panel stamping lines, the typical press spacing is 6.2 to 6.3 meters.
The seven-axis linear system features a lightweight design and high rigidity, which reduces inertia and boosts handling speed. Its compact structure and substantial load capacity make it well suited for the efficient transport of workpieces with large side‑wall dimensions.

In industries such as automotive and home appliances, sheet metal parts are typically manufactured through stamping, with many complex‑shaped components requiring multiple stamping operations to complete. In conventional industrial robot‑based production lines, when a robot retrieves a stamped part from one press and transfers it to the next, the part undergoes a 180° horizontal rotation during this process. If the application prohibits such rotational movement of the sheet metal, transferring the part between stations becomes impossible.
Our company’s R&D team has developed a rotary seven-axis system that addresses the challenge of transferring sheet metal between processes in situations where rotational movement is prohibited.

As consumer demand for diverse vehicle aesthetics continues to grow, the trend toward multi‑model, small‑batch production and even personalized customization is gaining momentum. This has led to increasingly diversified body panel designs, necessitating precise orientation adjustments of stamped parts during the stamping process and requiring handling robots to be equipped with pose‑adjustment capabilities.
Our company’s R&D team has developed a high-speed, flexible stamping and handling robot featuring seven servo axes—three linear axes, one speed‑multiplier axis, and three rotary axes—that seamlessly balances high‑speed material handling with flexible pose‑adjustment capabilities, enabling it to accommodate a wide range of complex molds.

High flexibility: Six-axis robots offer numerous degrees of freedom, enabling them to perform complex trajectory‑based motions—such as workpiece flipping and multi‑angle pick-and-place—while adapting seamlessly to different molds and product changes. Through programming, production takt times and process paths can be rapidly adjusted, meeting the demands of mixed-model, multi‑product line operations.
High precision and stability: Handling repeat positioning accuracy reaches ±2 mm, ensuring consistent stamped parts and reducing the scrap rate.
High‑efficiency continuous production with seamless end-to-end automation, achieving a cycle rate of 6–9.5 cycles per minute (depending on part complexity). Operates continuously 24/7, significantly boosting equipment utilization (OEE).

The positioning of the transfer automation system is defined in a Cartesian coordinate system, with clamping/releasing, lifting/lowering, and feeding/reversing all driven by linear actuation modules. It employs pneumatic quick‑change couplings and is powered by servo motors, delivering rapid step response and minimal repeat positioning error.
The FOL depalletizer consists of a loading carriage, a magnetic fan, a depalletizing unit, a conveyor, and a centering mechanism. The depalletizing unit is driven by two-axis servo motors, enabling horizontal movement along the X‑axis and vertical movement along the Z‑axis.

The dual-arm feeder features a typical X‑Y‑Z axis configuration and offers two operating modes—Transfer and Feeder. It can cyclically perform actions such as clamping, lifting, feeding, lowering, releasing, and returning, enabling rapid handling of sheet materials.

The transfer method is suitable for applications with short stamping strokes, wide column spacing, and narrow dies. It is particularly well‑suited for handling long, thin sheet materials. The robot’s X‑axis and the end‑effector gripper can remain inside the press without interfering with each other, minimizing press‑cycle time and helping to reduce the overall line takt time.

It can achieve independent automatic boxing of two items at speeds of 16 SPM or lower.
It can meet various packaging requirements for inner and outer panels, including suspended, spaced‑suspended, stacked, and spaced‑stacked configurations.
Based on instructions from quality inspectors or data from the automated visual inspection system, defective parts can be placed in separate frames or collected manually at the end of the line.
During the full-line die changeover, the end effector can be automatically replaced.
Material rack turnover can be handled by AGV transport or forklift transport.

Stamping automation relocation services are designed to meet enterprises’ needs arising from factory relocations, production capacity realignments, and other requirements, offering professional relocation of presses and automated equipment. From preliminary equipment assessment and solution planning to disassembly, transportation, and installation‑commissioning, we execute every step with meticulous care to ensure the safe and efficient transfer of equipment to the new site, enabling a swift resumption of production.
The upgrade and modernization services focus on leveraging advanced technologies to enhance the level of automation in stamping operations. By optimizing key processes—including existing equipment control systems, material handling workflows, automated handling systems, and one‑click die‑change capabilities—these services enable highly efficient, precise, and intelligent stamping production, thereby comprehensively improving both production throughput and product quality.

The online quality‑inspection system for automotive sheet‑metal stampings automatically retrieves the appropriate visual‑inspection recipe based on the part’s model. Leveraging advanced robotic vision technology, it integrates deep‑learning algorithms and image‑processing techniques to emulate the human visual system, enabling comprehensive, high‑precision inspection of stamped sheet‑metal components. This replaces manual quality checks, enhances inspection reliability and stability, and significantly reduces the likelihood of defective parts reaching the next stage.
Defect types detected: The system can accurately identify a variety of common defects in formed sheet metal parts, including dents and bumps, press‑induced scratches, deformation, cracking, wrinkling, porosity, and insufficient holes.

With the widespread adoption of aluminum alloy materials for automotive exterior panels, dry‑type cleaning machines—suitable for both steel and aluminum sheets—are increasingly favored by customers, particularly for aluminum panel cleaning. Boasting advantages such as high efficiency, environmental friendliness, and low maintenance costs, dry‑type sheet‑metal cleaners have become an essential piece of equipment in modern industrial production, especially in stamping lines where stringent cleaning standards are required.

It is used to apply drawing oil evenly to both the top and bottom surfaces of ordinary steel sheets and galvanized steel sheets. Depending on the preset mode, deep-drawing oil can be sprayed onto both sides of the blank. The spray volume is adjustable as needed. The oiling machine can be equipped with a traveling system and an AC variable-frequency drive, enabling it to move along installed guide rails and perform both in-line and off-line operations. Detection devices are installed at the entry and exit points to ensure interlocking across the entire production line.

A belt conveyor is a material-handling device widely used in industrial production. It transports materials horizontally, at an incline, or vertically by means of the continuous movement of a conveyor belt. Characterized by its simple structure, reliable operation, and ease of maintenance, it is an indispensable piece of equipment in modern manufacturing.
The infeed belt conveyor is a critical component of the stamping automation line, responsible for automatically conveying cut‑to‑size sheet metal to the press’s loading station. With its efficient and precise conveying system, this equipment ensures the line’s continuity and stability, boosts production efficiency, minimizes manual intervention, and reduces manufacturing costs.
