Ceramic tile flatness on-line detection method

Abstract

The invention relates to a ceramic tile flatness on-line detection method including a device and a detection method. The device includes a detection support fixed on a conveyor belt framework, non-contact distance measuring sensors, and a computer. A detection plane in parallel with a conveyor belt is arranged on the detection support. Five sensors are fixed on the detection plane and face the conveyor belt. The sensors synchronously collect distance data from conveyed ceramic tiles. The computer connected to the sensors calculates slopes and compares the slopes with a standard slope so as to judge whether the ceramic tiles are qualified or not. A photoelectric switch is arranged on the conveyor belt framework. A photoelectric switch signal controls the collection action of the sensors after being sent to the computer. The non-contact distance measuring sensors make the conveyor belt nonstop on-line detection possible. The on-line detection efficiency is improved, and vibration errors will not be caused by frequent pause and starting, and the fast detection demand of a production line can be satisfied.

Description

Technical field: [0001] The invention belongs to the field of detection equipment, and in particular relates to an online detection method for the flatness of ceramic tiles, in particular, a non-contact distance measuring sensor is used as a detection method for data collection. Background technique: [0002] At present, enterprises generally use the method of random inspection to detect the flatness of ceramic tiles, which is compared with standard plates and realized by manual discrimination, resulting in missed inspections; however, using existing standard measurement tools for manual inspection, its efficiency is also relatively Low, it is difficult to meet the detection needs of mass production. [0003] Application number 201120578899.7 discloses an automatic measuring device for the thickness of ceramic tiles. It includes a transmission line frame, a slide bar bracket, a slide bar and a displacement sensor, and the displacement sensor and an electrical control system...

AI Technical Summary

Problems solved by technology

When using the present invention, the thickness of the ceramic tiles is automatically measured on the production line through the displacement sensor, which solves the problems of high manual measurement costs and large errors in the past. The disadvantage of the device is that although it can be detected online, the ceramic tiles are transported to the measured In the area, the detection needs to be paused, and the displacement sensor needs to be driven down to the surface of the ceramic tile to form contact, and then it needs to move along the slide bar for detection to realize the detection of the thickness of a row in the horizontal direction; along the direction of travel of the ceramic tile, that is It is necessary to restart the conveyor belt to move the ceramic tiles to another position, and retest the thickness parameters at the new position. At least three tests need to be completed, resulting in low efficiency and it is difficult to meet the needs of online testing.
