Embodiment Construction

[0048] The present invention will be further described below in conjunction with examples and accompanying drawings, but should not limit the protection scope of the present invention with this.

[0049] see figure 1 , figure 1 It is a structural schematic diagram of the circular part arc dispensing device of the present invention. The composition of the circular part arc dispensing device of the present invention includes a mechanical module, an image acquisition module, an image processing module, a glue dispensing module and a control module5 parts. The control module is used to control the operation of the device. The mechanical module is used to transport the parts to be dispensed to the image acquisition module for taking pictures, and then to the dispensing module for circular dispensing. The image acquisition module is used for The parts to be dispensing are photographed and the images are transmitted to the image processing module for processing, and the dispensing ...

Abstract

The invention relates to a cambered surface dispensing device and method, and belongs to the field of machine vision and precise dispensing. The cambered surface dispensing device comprises a mechanical module, an image acquisition module, an image processing module, a dispensing module and a control module. According to the cambered surface dispensing device, a camera is used for collecting images of annular parts, circle center coordinates of the parts are obtained through an image processing algorithm, and charging tray position compensation is conducted; a needle head image is acquired byusing the camera, a needle head is manually finely adjusted to enable the circle center of the needle head image to coincide with the calibrated baseline, and needle head position compensation is performed; and all parts of the device are subjected to linkage control through a computer, and therefore automatic dispensing of the cambered surface of the annular part is achieved. According to the device and the method, the whole system is controlled by adopting a control program, and the device and the method have the advantages of realizing four-dimensional linkage, full automation and high-precision dispensing.

Description

technical field [0001] The invention relates to a machine vision-based arc surface glue dispensing device and method for small circular ring parts, belonging to the field of machine vision and precision glue dispensing. Background technique [0002] Navigation systems for moving objects such as rockets, missiles, aircraft, and ships must obtain speed and position information. Quartz accelerometer can be installed in a moving object to directly measure its acceleration, and obtain speed and position information through integral calculation, with high measurement accuracy and good dynamic performance. Inertial devices and instruments such as quartz accelerometers are high-precision components, and high-precision components are composed of several precision parts such as small circular parts. Dispensing of circular parts is a difficult point in dispensing and assembly of inertial devices, and its accuracy directly determines the performance of inertial devices and instruments....
