Embodiment Construction

[0051] In this embodiment, a placement machine control method using a hierarchical state machine is applied to a production environment composed of a host computer, a hierarchical state machine, and a placement machine. First, the placement work of the placement machine is summarized Analysis, decomposing the working state of the placement machine into multiple sub-states in the hierarchical state machine, linking the different sub-states of the placement machine through event-driven transfer, and then using the command event scheduler to manage the command and event queue scheduling. On the one hand The information that the subsystem interacts with is encapsulated as an event for transmission, and the sub-state is converted through the different sub-states of the state module box after receiving the event and meeting the conditions. On the other hand, the instruction is sent to the corresponding subsystem to perform the task. Among them, the subsystem is a subsystem divided ac...

Abstract

The invention discloses a method for controlling a placement machine using a hierarchical state machine. The steps include: 1. decomposing the working state of the placement machine into a plurality of sub-states in the hierarchical state machine; Encapsulated as events and temporarily stored in the event queue, the event types are divided into subsystem events, control panel button events and human operation events; 3 Define an instruction event scheduler between the hierarchical state machine and the placement machine, and the instruction Composed of queues and event queues, it is responsible for event processing and forwarding. The invention can optimize the management and control of the placement component action of the placement machine, reduce the misoperation and safety accidents of the placement machine, thereby improving the performance and operation reliability of the placement machine.

Description

technical field [0001] The invention relates to the field of chip mounter electronics technology, in particular to a chip mounter control method. Background technique [0002] The fully automatic multi-head arch mounter equipment consists of mechanical devices such as multi-mounting heads, multi-suction nozzles, and multiple servo motor high-speed components. In the process of automatic placement of components, it involves servo motor motion control and substrate transmission motion. Components such as control, camera control, and image recognition systems perform corresponding actions, and process complex state switching through components to realize the processes of component suction, component recognition, component placement, and nozzle exchange, and combine advanced machine vision recognition technology to achieve fast The purpose of accurately placing components. This requires the coordinated processing of tasks such as machine vision, axis motion control, and placeme...
