Abstract

An X-ray multi-station detection device adopting automatic closed-loop control comprises a C-type arm rotary deflection motor, a C-type arm lifting motor, a C-type arm support rotating motor, a C-type arm frame walking motor, an detection vehicle walking motor, an detection vehicle platform rotating motor, a workpiece feeding and discharging motor, a workpiece feeding cylinder, a clamping motor, a rotary clamping motor, an annular roller table motor, a flat panel detector device, an X-ray tube device, a workpiece carrying motor, detection vehicle entering tracks, frame walking tracks, a C-type arm device, a workpiece feeding chain device, a workpiece discharging chain device, a rotary clamping device, a PLC (programmable logic controller) control device, an detection vehicle and an annular roller table. According to the device, the defects that the control precision is low, single workpiece is detected and few stations are detected due to the fact that a conventional open-loop control mode is adopted to control asynchronous motors are overcome, the PLC is utilized to complete the closed-loop control, the complex mechanical structure is controlled simply and can be subjected to multi-station detection, automatic detection can be realized in a detection process, accordingly, the operation time is saved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to an X-ray detection device, in particular to an X-ray closed-loop automatic control multi-station detection device controlled by an industrial PLC programmable controller to control an asynchronous motor. technical background [0002] In the traditional X-ray inspection equipment, the asynchronous motor is controlled by open-loop control. The open-loop control structure is relatively simple. Since there is no feedback loop, the control accuracy is relatively low. Once the output deviates from the set value, it cannot be corrected. In the traditional X-ray inspection, there is only one inspection line in the zero-degree working state. Due to its simple structure, the inspection workpiece is single and the inspection stations are relatively small, which cannot meet the customer's needs for multi-station inspection. Contents of the invention [0003] In view of the above problems, the present invention provides an X-ray closed-lo...

[0002] In the traditional X-ray inspection equipment, the asynchronous motor is controlled by the open-loop control method. The open-loop control structure is relatively simple. Since there is no feedback loop, the control accuracy is relatively low. Once the output deviates from the set value, it cannot be corrected.

In the traditional X-ray inspection, there is only one detection line of zero-degree working state. Due to its simple structure, the detection workpiece is single and the detection stations are relatively small, which cannot meet the needs of customers for multi-station detection.
