Compact multi-axis drive and control stacked structure

Abstract

The invention provides a compact multi-axis drive and control stacked structure, which is composed of a central control board, a front end board and a plurality of amplifier modules. The central control board and the front end board are polygonal, are stacked in parallel, are fixed through a structural member, and transmit electric signals through a connector. The amplifier modules serve as a whole and are sequentially fixed to the polygonal edges of the central control board and the front end board through structural members, electric signal connection with the upper central control board iscarried out through a bus communication interface, electric signal connection with the lower front end board is carried out through a power interface, and the two interfaces are both in a hard connection mode. And each amplifier module receives control information from the central control board, drags one or more motors to operate, and realizes partial control functions of the one or more motors originally realized by the central control board as required. The compact multi-axis drive and control stacked structure adopts a modular design, provides configuration flexibility and maintenance convenience for customers, is high in power density, and can simplify customer wiring.

Description

technical field [0001] The invention relates to a multi-motor transmission shaft motion controller stacking structure, in particular to a compact multi-axis drive control stacking structure. Background technique [0002] Mechanical equipment, especially large-scale mechanical equipment, usually includes multiple motor drive shafts. The motion controller is used to control the coordinated action between multiple axes, and the driver matching the number of motor shafts is used to drive the motor to complete the command action. [0003] In the prior art, traditional multi-axis driving and control methods such as figure 1 As shown, one motion controller controls multiple drives, and one drive drives one or more motors to complete command actions. Communication cables, interconnected power supply cables, common bus cables, etc. need to be interconnected between the motion controller and each driver. The advantage of this method is the modular structure, the number of axes and d...

Problems solved by technology

However, this stack structure also has disadvantages: maintenance is inconvenient, due to the centralized design, if any axis fails, the centralized circuit board needs to be replaced, and it is not a modular design, and the number of axes and axis power cannot be flexibly configured according to customer needs

At the same time, the power board in this stack structure tends to have the largest area, and the area of ​​the control board and radiator is much smaller than that of the power board. Therefore, this stack structure results in low system space utilization and low power density.
