Problems solved by technology

However, due to cost considerations in terms of hardware, the brand models and interface types of various components are various. In terms of software, functions can be realized by writing program statements, and the forms are also strange, which brings great difficulties to the maintenance and spare parts management of line-related equipment in the later stage. It poses a great challenge, and of course it does not have the possibility of large-scale promotion and use

Embodiment Construction

[0033] The present invention is described in detail below in conjunction with accompanying drawing:

[0034] The present invention realizes the function of the welding line double fixture switching control system through hardware design and software programming, and through the standardized development of software and hardware. The specific content is as follows:

[0035] 1. Hardware modularization: Based on the related hardware of Siemens SINAMICS S120 drive system, it includes five core components including control module, power module, dual motor control module, braking module and motor. refer to figure 1 , the core module is the hardware composition of hardware standardization. The functions of each core module are as follows:

[0036] 1. Control module: the brain of the drive system, responsible for controlling and coordinating all modules in the entire system.

[0037] 2. Power module: the rectifier module, which rectifies the three-phase AC power into DC power and su...

Abstract

The invention belongs to the technical field of automobile body-in-white welding, and relates to a welding line double-clamp switching control method. A core module of a hardware system is formed by depending on related hardware of a Siemens SINAMICS S120 driving system, connection of more network types and a wider application range are achieved by changing some parts in the core module, a functional block suitable for programming software Step7 is developed corresponding to the core module of the hardware system, and therefore, functions of a double-clamp switching control system are fulfilled. The method comprises the steps of 1, judging whether connection and communication between the core module and an external network is normal or not; 2, judging whether external operation conditionsare met or not; 3, judging whether related state word receiving is normal or not; 4, mode selection: selecting a positioning mode and an adjusting mode; 5, judging whether operation conditions are metor not; and 6, starting operation. Switching driving requirements of all clamps of a welding production line from a split line to a main welding line can be met, software control standardization is achieved, and the software development period is shortened.

Description

technical field [0001] The invention belongs to the technical field of automobile body-in-white welding and relates to a method for controlling switching of double fixtures in a welding line. Background technique [0002] At present, the double fixture switching control system of the automobile body-in-white welding production line is widely used, and many related control technologies have also been derived. However, although various control technologies can achieve the same function, there is no modular development of software and hardware, resulting in a variety of control methods for similar fixture switching systems, which brings great benefits to later production line maintenance and spare parts management. big pressure. [0003] In the field of automobile body-in-white welding and manufacturing, it has long been a history that one welding line can only produce one model, and the flexible production of multiple models in the production line has long been the mainstream...
