Problems solved by technology

[0002] The assembly of instrument components is a complex process with extremely high precision requirements. In the traditional assembly of instrument components, in order to ensure the assembly accuracy of the instrument assembly components, the instrument assembly components are generally assembled by manufacturing jigs corresponding to the instrument assembly components. Positioning and ensuring the assembly accuracy between the instrument assembly components through the assembly accuracy between the fixtures, although this method can guarantee the assembly accuracy of the instrument assembly components to a certain extent, but this method also has low assembly efficiency, Due to the high loss rate of instrument assembly components, the need to manufacture fixtures of different specifications, high assembly costs, and difficulty in ensuring accuracy, in order to improve the assembly efficiency of instrument assembly components, reduce the report loss rate of instrument assembly components and ensure assembly accuracy, the present invention proposes A CCD image detection module and calibration method for precise assembly of instrument components is proposed, which solves the defects existing in the assembly process of traditional instrument assembly components on the basis of visual inspection based on CCD industrial cameras

Embodiment 1

[0037] A CCD image detection module for precise assembly of instrument components, such as figure 1 As shown, it includes a table 1 and an assembly platform 2 installed on the table 1. The CCD image detection module also includes a levelness detection CCD assembly 01 and a concentricity detection CCD assembly 02 installed on the table 1. The levelness The detection CCD assembly 01 is installed on the front end of the assembly part, and the concentricity detection CCD assembly 02 is installed on the rear end of the assembly part; the concentricity detection CCD assembly 02 is vertically installed on the upper and lower sides of the assembly platform 2; the levelness detection The CCD assembly 01 and the concentricity detection CCD assembly 02 are respectively connected with external image processors.

[0038] Before the assembly of the instrument components, the lower jig is first clamped to the assembly platform 2 by the manipulator for positioning and fixing, and then the lev...

Embodiment 2

[0044] This embodiment is further optimized on the basis of embodiment 1, such as figure 2 As shown, the concentricity detection CCD assembly 02 includes an upper concentricity detection CCD021 and a lower concentricity detection CCD022, the upper concentricity detection CCD021 is installed above the assembly platform 2, and the lower concentricity detection CCD022 is installed on the assembly platform 2 below.

[0045] The concentricity detection CCD assembly 02 includes the upper concentricity detection CCD021 and the lower concentricity detection CCD022. The lower concentricity detection CCD022 is used to detect the alignment and lowering assembly process between the lower fixture and the lower frame, the lower frame and the swing piece concentricity; because the diameter of the pendulum piece is larger than the diameter of the lower frame, the field of view of the lower concentricity detection CCD022 will be partially blocked by the pendulum piece. The upper concentricit...

Embodiment 3

[0048] This embodiment is further optimized on the basis of the above-mentioned embodiment 1 or 2, a checkerboard grid is arranged between the upper concentricity detection CCD021 and the lower concentricity detection CCD022; the upper concentricity detection CCD021 and the lower concentricity A ring light source is installed at the lens of the detection CCD022.

[0049] When installing the upper concentricity detection CCD021 and the lower concentricity detection CCD022 on the upper and lower sides of the assembly platform 2, the ideal situation is that the axes of the upper concentricity detection CCD021 and the lower concentricity detection CCD022 should be strictly parallel and coincident. In the process, it is difficult to ensure that the axes of the upper concentricity detection CCD021 and the lower concentricity detection CCD022 are strictly parallel and coincident. Therefore, a checkerboard grid is set between the upper concentricity detection CCD021 and the lower conce...

Abstract

The invention discloses a CCD image detection module of accurate assembly of instrument components. The image detection module of instrument component assembly precision detection is formed by a horizontality detection CCD component installed on a table top and concentricity detection CCD components installed on the upper and lower sides of an assembly table, and the rapid and accurate detection of the assembly precision of the instrument components is achieved. The invention further discloses a CCD image calibration method of accurate assembly of instrument components. The method comprises the following steps: step A, performing fixed positioning on a lower fixture on the assembly table; step B, performing, by the horizontality detection CCD component, assembly surface horizontality detection on the instrument components; and step C, performing, by the concentricity detection CCD components, concentricity detection before the assembly of the instrument components, and performing the concentricity detection in a placement assembly process of the instrument components in real time. The CCD image detection module disclosed by the invention have the beneficial effects of having higherdetection precision and higher detection efficiency, effectively ensuring the assembly surface horizontality of the instrument components, effectively ensuring the accuracy of assembly operations, and reducing the assembly cost.
