Detection system and method for detecting glass heating wire resistance and whether it is broken

Abstract

The invention discloses a detection system and a detection method used for detecting resistance of a glass heating wire and detecting whether wire breakage exists. The detection system comprises a rack, a conveying wire arranged on the rack and used for conveying glass, a direct current power supply, and a thermal imager connected with an outer computer, wherein the conveying wire comprises a resistance detection section and a lower sheet conveying section; the resistance detection section is provided with a locating device used for locating the glass; a resistance detection device used for detecting the resistance of the glass is arranged above the resistance detection section, and is provided with two probes capable of lifting up and down; the direct current power supply is electrically connected with the two probes; and the thermal imager is arranged above the resistance detection section. According to the detection system and the detection method, the resistance of the glass heating wire and whether the wire breakage exists can be detected simultaneously, so that the cost of purchasing two sets of equipment is lowered; the production efficiency is improved; and the detection system and the detection method have significance in improving the detection precision and the automation degree of the equipment.

Description

technical field [0001] The invention relates to a glass detection device, in particular to a detection system and a detection method for detecting the resistance of a glass heating wire and whether the wire is broken. Background technique [0002] There are heating wires installed on the automobile glass. The function of the heating wire is to generate heat after being energized to eliminate the frost and fog generated on the automobile glass. In order to improve the defrosting effect, the heating wires on the automobile glass are usually distributed in a mesh shape. [0003] In the current glass processing industry, the resistance of the glass heating wire is mainly detected manually. During the detection, the worker holds the positive and negative electrodes of the resistance measuring instrument with his hand, and aligns the positive and negative electrodes of the resistance measuring instrument with the glass heating wire. Two access points, read according to the display...

Problems solved by technology

Although this device realizes the online detection of glass resistance, improves the consistency and detection accuracy of resistance detection, reduces the labor intensity of workers, and improves production efficiency, but the device cannot detect whether there is a disconnection of the heating wire on the glass. Use other equipment to detect whether the heating wire on the glass is broken, which not only increases the cost of the manufacturer to purchase two equipment, but also reduces production efficiency due to the need for secondary inspection
