Automatic assembly equipment for medical equipment automatic assembly equipment

 

The automatic assembly machine of medical equipment automatic assembly equipment requires detailed process specifications, and the process design is much more complicated than the manual assembly process design. On the one hand, it is necessary to determine the assembly basis in accordance with the common requirements of manual assembly, such as the division of assembly units, so as to solve the problems of assembly dimension chain and balance process tact.

On the other hand, starting from the product design stage, the process requirements of fully automatic assembly should be fully considered, the structure of the parts should be designed rationally, and the process flow of the appropriate degree of automation should be formulated. When developing a fully automatic assembly process, the following issues should be paid attention to:

1. Fully automatic assembly machine process and process system diagram. The development of process specifications and system diagrams needs to determine the reference parts and their movement along the assembly station; determine the loading, feeding, and selection of orientation equipment for all components; specify the sequence of all assembly operations. When preparing automatic assembly process specifications and system drawings, it is necessary to analyze the product and its parts from the perspective of assembly automation.

2. The product and its assembly unit can be divided into:

1) The use and structure are the same, but the size and material have different effects on the assembly process.

2) The structure is slightly different, but it will not cause substantial changes during the assembly process.

3) The structure is different, but it does not affect the general drawing of the drawing assembly process. For assembly units with basically the same characteristics, typical process system diagrams or typical process specifications can be developed.

3. The degree of automation of the assembly machine needs to be determined according to the overall economic benefits and the maturity of the typical assembly process.

In the general threaded connection process, a single-axis working head is often used, and the torque is usually detected by manual operation. Part loading and unloading devices, assembly and disassembly assembly machines, assembly and assembly quality inspections, unqualified assembly rejections and other operations are less automated. The transfer and posture conversion, removal, connection, balance, connection detection and other operations of assembly parts between stations require more automation. In addition to semi-automatic assembly, manual assembly can also be carried out for assembly processes with complex shapes, small batches, or less mature assembly processes or inefficient assembly efficiency.

4. Measures to improve the automation level and comprehensive economic benefits of the assembly machine.

1) The promotion of product structure, the operability of the series and the structure of the component itself are the basis for improving the level of assembly automation. Product design must fully consider the requirements of automatic assembly.

2) The use of general-purpose equipment and components, automatic assembly equipment becomes more and more standardized, general-purpose, replacement parts working heads, assembly fixtures, conveyors, etc., make the system flexible.

3) From single assembly automation to full automation. Combine the basic assembly workflow, such as the connection with processing and inspection processes, to achieve larger-scale automated manufacturing.

4) Assembly system control. Use computer and numerical control equipment to directly control operation, transmission equipment, equipment and control system flexibility.

5) The application of non-synchronous automatic assembly attraction can reduce the impact of local failures on the entire system, and facilitate the combination of assembly systems with different automation levels and different production cycles.

5. The processing speed of automatic assembly. After determining the automatic assembly mechanism and combination design, the computer can be used to determine the movement and the completion time of the movement in the assembly process. In the initial design stage of automatic assembly equipment, time-consuming calibration of various devices in the equipment can be used to estimate processing time. The multi-station rigid conveying system must ensure the synchronization of the assembly work in each process.
