Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1-2, a multi-line camera stitching device includes: a left baffle 1, a right baffle 2, a camera mounting plate 3, four CCD cameras 4 (vision detection cameras), and a light source module 5.
The left baffle plate 1 and the right baffle plate 2 are arranged in parallel left and right, and are used for fixedly mounting the multi-linear-array camera splicing device on the product conveying track 6 on one hand and shielding external ambient light on the other hand so as to reduce the influence of stray light on product defect detection.
The inner sides of the left baffle plate 1 and the right baffle plate 2 are provided with a plurality of transversely arranged clamping strips 7, and the clamping strips 7 are matched with profile grooves on profiles on two sides of the product conveying track 6 in a direction. The left baffle plate 1 and the right baffle plate 2 are fixedly connected to profiles on two sides of the product conveying track 6 through bolts.
The camera mounting plate 3 is fixedly mounted at the top of the left baffle plate 1 and the right baffle plate 2, four camera mounting portions 8 extend outwards from four corners of the camera mounting plate 3, and four CCD cameras 4 are mounted at the bottom ends of the camera mounting portions 8 through camera mounting seats 9. Four CCD cameras 4 are uniformly arranged along the circumferential direction of the camera mounting plate 3.
Four camera mounting portions 8 extend outwardly from four corners of the camera mounting plate 3, and this arrangement is due to: the left baffle plate 1 and the right baffle plate 2 are required to be arranged at two sides of the product conveying track 6, the space between the left baffle plate 1 and the right baffle plate 2 is determined, and the width of the product conveying track 6 is not required to be set to be too large, so that only a single product can pass through the multi-linear-array camera splicing device at the same time, and the space between the left baffle plate 1 and the right baffle plate 2 is narrow; the array radius of the linear array camera is not too small, and the four camera mounting parts 8 extend outwards from the four corners of the camera mounting plate 3, so that the linear array camera can have enough array radius and save materials.
The number of CCD cameras 4 is set to four to be uniquely determined. When the number of the CCD cameras 4 is set to 2 or 1, the circumferential direction of the product cannot be completely detected; when the number of CCD cameras 4 is set to 3, 5 or more, there is always a case where the CCD cameras 4 are blocked by the left side barrier 1 and the right side barrier 2.
CCD camera 4 with camera mount pad 9 fixed connection, camera mount pad 9 with camera mounting panel 3 articulates, camera mount pad 9 with the hinge structure of camera mounting panel 3 sets up to: only the vertical pitching angle of the camera mounting seat 9 and the camera mounting plate 3 can be adjusted, and the horizontal rotation angle of the camera mounting seat 9 and the camera mounting plate 3 cannot be adjusted.
The light source module 5 is fixedly installed at the bottom of the camera mounting plate 3. The light source module 5 is in a flat cylindrical shape, and the light source module 5 has a larger light projection area and at least can completely cover the product conveying track 6. The lens of the CCD camera 4 always faces the central axis of the light source module 5, and even if the CCD camera 4 adjusts the vertical pitching angle relative to the camera mounting plate 3, the lens of the CCD camera 4 faces the central axis of the light source module 5.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
