Screw mounting and detecting integrated equipment based on machine vision and operating method for screw mounting and detecting integrated equipment

Abstract

The invention relates to screw mounting and detecting integrated equipment based on machine vision and an operating method for the screw mounting and detecting integrated equipment. The screw mounting and detecting integrated equipment comprises a rack, wherein the middle part of the upper part of the rack is provided with a clamping mechanism; a detecting mechanism is mounted on the rack above the clamping mechanism; the top of the rack is provided with a bolt mounting mechanism; the detecting mechanism is connected to an image acquisition card; and the image acquisition card is connected to an industrial-control computer. The screw mounting and detecting integrated equipment based on machine vision can be used for quickly completing a piano top cover clamping process and a hinge screw mounting process, and can be used for precisely detecting whether bolt mounting is qualified or missed by utilizing technologies such as image processing and pattern recognizing, so that assembly quality of the whole piano top cover is guaranteed.

Description

Technical field [0001] The invention relates to the field of machine vision inspection for piano panel production, and in particular to a machine vision-based screw installation and detection integrated equipment used for screw installation and screw missing installation detection of piano panels. Background technique [0002] The piano top cover is the most frequent and most conspicuous part of the piano when users use it. At the same time, the assembly of the piano top plate is a very important part of the piano production process. The assembly quality of this part directly affects the user's perception of product quality. [0003] The piano top cover is composed of a front top cover, a rear top cover, and a hinge. The existing assembly process has the following characteristics: the width of the front and rear top covers are inconsistent and a certain gap must be maintained when clamping, which is not convenient for flushing and clamping; There are many models, and the length, th...

AI Technical Summary

Problems solved by technology

[0005] (1) Due to the inconsistent heights of the front top cover and the rear top cover, there are certain difficulties in positioning during the assembly process. Traditionally, pads with different heights are used to assist the installation, but it is inconvenient to replace, and the piano top cover contains a variety of Different specifications, so that it is necessary to replace pads of different heights during the replacement process, and the operation will be more inconvenient;

[0006] (2) Due to the long length of the front top cover and the rear top cover, the length of the hinge is also very long, usually reaching about 2m. Therefore, the number of screws that need to be installed on the hinge is also large, and the number of single sides will generally be 40 Left and right, there are about 80 screws on both sides. Manual hand-held drills are used for screw assembly. The workload is heavy, and it is easy to miss the assembly, which seriously affects the assembly quality;

[0007] (3) When the traditional hand-held drilling rig is assembled, the vertical drilling of the screw cannot be well ensured, which is likely to cause defects such as drilling crookedness, and it is inconvenient for the operator to carry out hand-held operations, which affects work efficiency

[0009] Therefore, the traditional assembly method is not only time-consuming and labor-intensive, but also easily missed, which affects product quality
