Embodiment Construction

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] Such as figure 1 As shown, a vision-based automatic assembly method for sheet-type honeycomb ceramics includes the following steps:

[0019] (1) The camera captures the image of the plate-type honeycomb ceramics on the roller conveyor belt, and obtains its pose information after projection and shape matching algorithms. The real-time data is sent to the precision rotating roller device to correct its pose; specifically: the camera Installed on the top of the roller co...

Abstract

The invention discloses a vision-based automatic assembling method for plate type honeycomb ceramics, which comprises the following steps that a camera shoots a plate type honeycomb ceramic image on a roller conveying belt, pose information of the plate type honeycomb ceramic image is obtained through a projection and shape matching algorithm, and real-time data is sent to a precise rotating roller device to correct the pose of the plate type honeycomb ceramic image; a point cloud model of the plate-type honeycomb ceramics is obtained through binocular vision, defective honeycomb ceramic pieces are removed through a rod-pushing device after recognition is conducted through a point cloud matching algorithm, and meanwhile the adhered honeycomb ceramic pieces are segmented through segmentation grooves; a camera acquires a sorted monolithic honeycomb ceramic image, and the reverse side ceramic is turned over after feature matching; the camera obtains front single-chip ceramic pose information, the front single-chip ceramic pose information and expected assembly pose data are fused and then grabbed by a mechanical arm to achieve cross assembly, and binding and gluing are conducted in cooperation with the rotary mechanical device. Automatic assembly of the plate type honeycomb ceramics can be completed, the product stability and the assembly automation level are improved, and the operation cost is saved.

Description

technical field [0001] The invention relates to the technical fields of image processing, signal processing, control and robotics, in particular to a vision-based automatic assembly method for sheet-type ceramics. Background technique [0002] Honeycomb ceramics is a new type of ceramic product with a honeycomb-like structure. It has the characteristics of large surface area, good heat insulation, light weight, low thermal expansion coefficient, high temperature resistance, acid and alkali resistance, and is widely used in automobile exhaust gas treatment, flue gas Purification, regenerators, carriers and catalysts for chemical reactions, heat insulation materials for kilns, etc. The plate-type honeycomb ceramics used in waste gas treatment has strong anti-clogging properties, and its single-piece thermal stress resistance is strong, not easy to be damaged, the airflow is evenly distributed, and the turbulence is high. It has a high removal rate of harmful gases, and at the ...
