Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to an automatic positioning device for multi-specification flat panel and stepped panel. Background Technology

[0002] In machining, automated equipment, and assembly lines, flat and stepped plates of various sizes often need to be precisely placed on multi-layered structures for subsequent processing, assembly, or inspection. Traditional positioning mechanisms, lacking sufficient flexibility in terms of size and layering, often struggle to meet the positioning requirements of flat plates of different dimensions. Furthermore, traditional positioning mechanisms may suffer from inaccurate positioning and poor stability during operation, which not only affects production efficiency but can also lead to a decline in product quality.

[0003] To address the aforementioned issues, an automatic positioning mechanism for multi-specification, multi-layer flat panels has been developed. This automatic positioning mechanism offers greater flexibility and adaptability, capable of meeting the positioning needs of flat panels of different specifications in multi-layer structures. Furthermore, through precise design and manufacturing processes, this positioning mechanism ensures accuracy and stability in positioning, thereby improving production efficiency and product quality.

[0004] The application of automatic positioning mechanisms for multi-specification, multi-layer flat panels will greatly improve production efficiency and product quality in the manufacturing and mechanical engineering fields. With continuous technological advancements and expanding applications, this positioning mechanism will find wider application, making significant contributions to the development of industrial automation and intelligent manufacturing.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model provides an automatic positioning device for multi-specification flat plate steps, which has the following advantages:

[0022] 1. This multi-specification flat and stepped plate automatic positioning device is equipped with an X-axis drive assembly, an equidistant adjustment assembly, and positioning gripper assemblies tailored to different products. This allows the device to position flat or stepped plates of various specifications. Each gripper assembly is equipped with an individually controlled electric cylinder to drive the gripper fingers. Each main and auxiliary gripper assembly can operate independently or in multiple groups, satisfying the positioning needs of single-layer and multi-layer products, thus improving work efficiency. The multi-layer design allows the mechanism to simultaneously position multiple flat plates, enabling parallel multi-task processing and improving production line efficiency. The multi-specification design provides excellent scalability; the number of positioning layers and specifications can be increased or decreased according to actual needs to adapt to different production requirements.

[0023] 2. This multi-specification flat panel and stepped plate automatic positioning device can be divided into a reference side and a positioning side. The difference lies in that the positioning gripper assembly on the reference side is directly fixed to the corresponding mounting, while the positioning gripper assembly on the positioning side is driven by a cylinder. When positioning the product, the reference side positioning gripper assembly is driven directly to the designated position by a servo electric cylinder. The positioning gripper assembly on the positioning side is first driven to a certain position by a servo electric cylinder, and then the cylinder drives and clamps the plate, securing the workpiece and completing the product positioning. Therefore, the beneficial effects of this multi-specification flat panel and stepped plate automatic positioning device are mainly reflected in its high efficiency, flexibility, accuracy, durability, convenience, and expandability, providing a strong guarantee for the production line's operating efficiency and product quality.

Each X-axis drive component 3 controls the corresponding mounting frame component 4 to move upward along the X-axis. Each mounting frame component is equipped with eight sets of positioning gripper components 5, resulting in 32 sets of positioning gripper components 5. When one or more layers of panels are placed under the press 2, the operator can set different contact components 9 according to the different panels. The 32 sets of contact components can be adjusted in four directions (up, down, left, and right) to position one or more layers of panels. In special cases, an auxiliary positioning component 10 can be activated for auxiliary positioning. The auxiliary positioning component 10 includes a lifting plate component set in the bottom plate of the main frame 1. The lifting plate component is lifted upward by power devices on both sides to further position the panels above. During the positioning process, the equidistant adjustment component 6 can automatically adjust the spacing up and down to accommodate products of different thicknesses, thereby improving efficiency and enabling multi-layer product positioning.

[0060] This multi-specification flat and stepped plate automatic positioning device is equipped with an X-axis drive assembly, an equidistant adjustment assembly, and positioning gripper components 5 configured according to different products. This allows the device to support the positioning of flat or stepped plates of various specifications. Each positioning gripper component 5 is equipped with an individually controlled electric cylinder driving the gripper fingers. Each main gripper component 7 and auxiliary gripper component 8 can operate independently or in multiple groups, satisfying the positioning needs of single-layer and multi-layer products, thus improving work efficiency. The multi-layer design allows the mechanism to simultaneously position multiple flat plates, enabling multi-task parallel processing and improving production line efficiency. The multi-specification design provides good scalability; the number of positioning layers and specifications can be increased or decreased according to actual needs to adapt to different production requirements.

[0061] The automatic positioning device for multi-specification flat and stepped plates can be divided into a reference side and a positioning side. The difference is that the positioning gripper component 5 on the reference side is directly fixed to the corresponding mounting, while the positioning gripper component 5 on the positioning side is driven by a cylinder. When positioning the product, the reference positioning gripper component 5 is driven directly to the designated position by a servo electric cylinder. The positioning gripper component 5 on the positioning side is first driven to a certain position by a servo electric cylinder, and then the cylinder drives and clamps the plate material to clamp the workpiece and complete the product positioning.

[0062] In summary, the beneficial effects of this multi-specification flat plate and step plate automatic positioning device are mainly reflected in its high efficiency, flexibility, accuracy, durability, convenience, and scalability, providing strong guarantees for the production line's operational efficiency and product quality.
