The promotion of product structure, the structure operability of series and components themselves are the basis of improving the level of assembly automation. The requirements of automatic assembly must be fully considered in product design. The use of general equipment, components, automatic assembly equipment has become more and more standardized, general, replacement parts working head, assembly fixture, conveyor, etc., so that the system is flexible. From single assembly automation to full automation. Combined with the basic assembly workflow, such as the connection with the processing and inspection processes, to achieve a larger scale of automated manufacturing. Use computer and numerical control equipment to directly control the flexibility of operation and transmission equipment, equipment and control system. The application of asynchronous automatic assembly can reduce the influence of local faults on the whole system and facilitate the combination of assembly systems with different automation levels and different production beats.
The processing speed of automatic assembly, after determining the automatic assembly mechanism and combination design, the computer can be used to determine the completion time of movement and movement in the assembly process. In the initial design stage of the automatic assembly equipment, the processing time can be estimated by using the time-consuming calibration of various devices in the equipment. The multi station rigid conveying system must ensure that the assembly work of each process is synchronized. Using intelligent robot, the robot equipped with sensors can adapt to the changes of position and posture of components in a certain range, so as to complete various assembly operations.
In addition to semi-automatic assembly, manual assembly can also be carried out for assembly process with complex shape, small batch, or lower mature or inefficient assembly efficiency. Measures to improve the automation level and comprehensive economic benefits of the assembly machine.
On the other hand, from the product design stage, we should fully consider the process requirements of fully automatic assembly, reasonably design the structure of parts, and formulate the process flow with appropriate degree of automation. Process and process system diagram of automatic assembly machine. Specifies the sequence of all assembly operations. When preparing process specifications and system drawings for automatic assembly, it is necessary to analyze products and parts from the perspective of assembly automation. The use and structure are the same, but the size and material have different effects on the assembly process. The structure is slightly different, but will not cause substantial changes during assembly. General drawings with different structures but without influence on drawing assembly process. For assembly units with the same characteristics, typical process system diagrams or typical process specifications can be developed.
The automation level of the assembly machine needs to be determined according to the overall economic benefits and the maturity of the typical assembly process. In the process of general screw connection, the single axle working head is often used, and the torque is usually detected by manual operation. Parts loading and unloading device, assembly and disassembly assembly machine, assembly and assembly quality inspection, unqualified assembly rejection and other operations are less automated. More automation is required for inter station transmission and attitude conversion, clearing, connection, balancing, connection detection and other operations of the assembly.
