Referring to fig. 1 to 3 in combination, the present invention provides a visual inspection device for dual-conveyor synchronization adjustment, which is used for implementing deviation correction of a first conveyor 21 and a second conveyor 22.
The first conveyor belt 21 and the second conveyor belt 22 are parallel to a reference plane, that is, the planes of the first conveyor belt 21 and the second conveyor belt 22 are parallel, and meanwhile, the first conveyor belt 21 and the second conveyor belt 22 can be located on the same plane or different planes, and the vision detection device provided by the embodiment can realize synchronous deviation correction of the two conveyor belts.
Specifically, the visual inspection apparatus includes:
the detection light source 11 is configured to emit a first detection light, where the first detection light passes through the first conveyor belt 21, and forms a first deviation-correcting detection point a on the first conveyor belt 21, and in this embodiment, the detection light source 11 is a laser light source.
The reflection assembly is configured to reflect the first detection light to form a second detection light, where the second detection light is parallel to the first detection light and opposite to the first detection light, and the second detection light penetrates the second conveyor belt 22, and a second deviation-correcting detection point B is formed on the second conveyor belt 22.
It will be appreciated that the first conveyor belt 21 and the second conveyor belt 22 are made of transparent or translucent materials, so as to be able to transmit the first detection light and the second detection light.
By utilizing the reflection assembly, the detection light rays emitted by the same detection light source 11 can form deviation correcting detection points on the two conveyor belts at the same time, and the deviation correcting detection points are used as the basis to realize synchronous deviation correction of the two conveyor belts.
It will be appreciated that in one embodiment of the present application, the vision inspection apparatus further includes an imaging device 30 for photographing the first conveyor belt 21 and the second conveyor belt 22, and the imaging device 30 is used to photograph the first conveyor belt 21 and the second conveyor belt 22, and based on the position comparison result of the first deviation-correcting inspection point a and the second deviation-correcting inspection point B, the deviation-correcting adjustment of the first conveyor belt 21 and the second conveyor belt 22 is implemented.
In another embodiment of the present application, standard reference points may be set on the first conveyor belt 21 and the second conveyor belt 22, respectively, and the position of the first deviation correcting detection point a is compared with the standard reference point on the first conveyor belt 21 to perform deviation correcting adjustment of the first conveyor belt 21, and the deviation correcting adjustment of the second conveyor belt 22 is implemented in a similar manner, so that costs of the imaging device 30 and the image analysis system can be saved, and the method is suitable for application scenarios with low precision requirements and low cost budget.
In this embodiment, the reflection assembly includes a first reflection member 12, a second reflection member 13, and a third reflection member 14;
Specifically, the first detection light is incident on the first reflection position of the first reflection member 12, reflected by the first reflection member 12, the second reflection member 13 and the third reflection member 14 in sequence, and then incident on the second reflection position of the first reflection member 12, and reflected by the first reflection member 12 at the second reflection position to form the second detection light.
Wherein the first reflecting member 12 is disposed obliquely to the reference plane, and the distances between the first reflecting position and the second reflecting position and the reference plane are different.
The second reflecting element 13 and the third reflecting element 14 are used for making the finally formed second detection light and the first detection light symmetrical with respect to the standard central axis of the first conveyor belt 21 and the second conveyor belt 22, so that the first deviation-correcting detection point a and the first deviation-correcting detection point a can be used as deviation-correcting basis, and it can be understood that the standard central axis is the central axis between the first conveyor belt 21 and the second conveyor belt 22 in the standard state.
Further, the third reflecting member 14 includes a first sub-reflecting surface and a second sub-reflecting surface, the first sub-reflecting surface and the second sub-reflecting surface are perpendicular to each other, and the first detection light is reflected by the second reflecting member 13 and then sequentially enters the third reflecting position of the first sub-reflecting surface and the fourth reflecting position of the second sub-reflecting surface, where the distance between the fourth reflecting position and the second reflecting position reference plane is the same.
By means of the third reflecting element 14, a change in the position of incidence of the second detection light upon return to the first reflecting element 12 is thus achieved.
In this embodiment, the first reflecting member 12 and the second reflecting member 13 are triangular prisms, and the third reflecting member 14 is formed of two triangular prisms perpendicular to each other.
Further, in this embodiment, in order to implement synchronous deviation correction of the first conveyor belt 21 and the second conveyor belt 22, the visual detection device for synchronous adjustment of the dual conveyor belts further includes a first scale and a second scale.
In one embodiment, a first scale is provided on the first conveyor belt 21 and a second scale is provided on the second conveyor belt 22. At this time, the imaging device 30 is used to take an image and compare the difference between the scales of the first deviation correcting detecting point a and the second deviation correcting detecting point B on the first conveyor belt 21 and the second conveyor belt 22, and if the difference exists, the position of the conveyor belt is adjusted until the first deviation correcting detecting point a and the second deviation correcting detecting point B are adjusted to have no difference between the scales on the first conveyor belt 21 and the second conveyor belt 22.
In another embodiment, the first scale is suspended above the first conveyor belt 21, the second scale is suspended above the second conveyor belt 22, the first detection light passes through the first scale to form a first correction standard point, and the second detection light passes through the second scale to form a second correction standard point. When correcting deviation, the first conveyor belt 21 and the second conveyor belt 22 are adjusted by adjusting the first conveyor belt 21 so that the first deviation correcting detection point A is coaxial with the first deviation correcting standard point and the second conveyor belt 22 so that the second deviation correcting detection point B is coaxial with the second deviation correcting standard point, so that the deviation correcting adjustment of the first conveyor belt 21 and the second conveyor belt 22 is realized.
