Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to an automatic assembly device and an assembly method for a pressing plate. Background Art

[0002] As an important connector widely used in various mechanical equipment, the assembly quality of the pressure plate directly affects the performance and life of the final product. Traditional manual assembly of pressure plates is not only time-consuming and labor-intensive, but also due to the instability of manual work, it is often difficult to ensure the consistency of each assembly link, resulting in uneven product quality. In addition, manual operation also has problems such as low production efficiency, high labor costs and potential safety hazards.

[0003] With the continuous improvement of product quality requirements and the continuous strengthening of the pursuit of production efficiency in the manufacturing industry, the traditional manual assembly method can no longer meet the needs of modern industrial production. The development of automation technology has provided a possible solution to this problem. By adopting automated equipment and technology, efficient and precise assembly of press plates and other related parts can be achieved, thereby significantly improving production efficiency and product quality. However, although automated assembly technology has been widely used in many fields, its application in the field of press plate assembly is still in its infancy. Most existing solutions are limited to the automation of a single process and lack a complete and integrated automated assembly system. This is mainly because the assembly process of the press plate involves multiple different types of parts (such as press plates, nuts, screws, spring washers and gaskets). These parts have different sizes and shapes, and require highly customized manipulators and tools to complete precise grasping and positioning; although there are some automated equipment on the market that can assist in completing certain assembly steps of the press plate, they usually have the following shortcomings: 1. Most equipment can only be used for assembly of specific types or sizes of press plates; 2. Once the product model needs to be changed or the assembly process needs to be adjusted, a major transformation of the entire system is often required. Summary of the invention

A method for automating the assembly of a pressing plate, characterized in that: The method comprises the following steps: S1, the pressing plate feeding device (1) conveys the pressing plate to be processed to the placement box (1-5) at the end; S2, the first mechanical arm gripper (3) grabs the pressing plate and places it into the punching device (2), and the punching device (2) bends and punches the pressing plate; S3, the third mechanical arm gripper (12) grabs the pressing plate after stamping and places it into the annular notch (10-1) outside the pressing plate indexing plate (10); S4, the parts indexing plate (9) starts to rotate, the gasket feeding device (7) feeds the gasket into the fixture base (9-2) on the parts indexing plate (9), then the parts indexing plate (9) rotates 90° counterclockwise, the spring gasket feeding device (6) feeds the spring gasket into the fixture base (9-2) and places it above the gasket, then the parts indexing plate (9) rotates 90° counterclockwise again, the nut feeding device (5) feeds the nut into the fixture base (9-2) and places it above the spring gasket, and they are stacked and fixed in sequence; S5, the parts indexing plate (9) is rotated 90° counterclockwise again and moved below the pressure plate indexing plate (10); S6, the pressing plate indexing plate (10) rotates 90° counterclockwise, and the screw feeding device (4) feeds the screw to the top of the pressing plate after stamping; S7, the pressure plate indexing plate (10) is rotated 90° counterclockwise again to move the pressure plate and the screw to the top of the stacked nuts, spring washers and gaskets; S8, the screw tightening device (13) moves downward and tightens the screw rod, the pressure plate and other components to complete the assembly; S9, the parts indexing plate (9) moves downward and leaves the pressure plate, and the pressure plate indexing plate (10) simultaneously rotates 90° counterclockwise again to the next station; S10, the second mechanical arm gripper (11) grabs the transferred pressing plate and places it in the storage box (8).
