Problems solved by technology

[0004] However, the existing insulation detection method for the conveying part of the spreader is to use manual offline measurement regularly, with a frequency of 3 sets per day. After the offline cleaning of the spreader is completed, the general-purpose shaker will perform manual shaking insulation detection on the conveying part of the spreader. Low detection efficiency and poor timeliness

[0065] Wherein, t...

Embodiment 3

[0075] see Figure 8 , is a structural schematic diagram of an insulation detection device for a spreader provided by an embodiment of the present invention. Controls include:

[0076] The data acquisition module 301 is used to obtain the resistance value to be measured; wherein, the resistance value to be measured is obtained by connecting the resistance between the moving mechanism and the pusher device, and the resistance between the pusher device and the conductive carbon brush in parallel;

[0077]The judging module 302 is configured to judge that the insulation state of the spreader is abnormal when the resistance value to be measured does not meet the preset insulation condition of the spreader.

[0078] Further, it also includes: an alarm module, which is used to issue an alarm after determining that the resistance value to be measured does not meet the preset insulation condition of the spreader.

[0079] Further, the preset insulation condition of the spreader incl...

Abstract

The invention discloses an insulation detection method, system and device of a lifting appliance and a storage medium. The lifting appliance comprises a moving mechanism, a head push device and a conductive carbon brush; the method comprises the following steps: acquiring a to-be-detected resistance value; wherein the to-be-detected resistance value is obtained by connecting the resistance betweenthe moving mechanism and the head push device and the resistance between the head push device and the conductive carbon brush in parallel; and when the to-be-detected resistance value does not meet the preset lifting appliance insulation condition, judging that the insulation state of the lifting appliance is abnormal. The insulation state of the lifting appliance can be judged according to the parallel resistance of the lifting appliance conveying part, so that the insulation detection instantaneity of the lifting appliance conveying part is improved.

Description

technical field [0001] The invention relates to the technical field of insulation detection of a spreader, in particular to an insulation detection method, device, system and storage medium of a spreader. Background technique [0002] Electrophoresis anti-rust is a crucial part in the manufacturing process of automobiles, and the quality of electrophoresis is the fundamental guarantee for the anti-corrosion and anti-rust performance of automobiles. The current automobile painting process is to use the spreader to carry the body in white to carry out various pre-treatment electrophoresis processes. When the body-in-white undergoes the electrophoresis process, the spreader collects electrons in contact with the conductive copper plate powered by the rectifier, and forms a circuit with the electrophoretic liquid in the electrophoresis tank, so that the charged paint ions move to the cathode, and the alkalinity generated on the surface of the cathode The substance acts to form ...
