In this embodiment, the camera and the light source (part of the image capturing mechanism) are fixed to two aluminum profiles (the second supporting portion 100 and the first supporting portion 90) located on the side of the assembly line (the conveyor line 70), and the top of the aluminum profile is further passed through a movable part (the first sliding portion 110), so that the aluminum profile above the assembly line can freely rotate 180 °. When the camera and the light source are required to be transferred to the position right above the assembly line from the side, the aluminum profile above can be rotated to the position right above the assembly line, then the staff loosens the rotary button for fixing the light source, then the light source is moved to the top along the side edge of the aluminum profile, a space exists at the joint of the two aluminum profiles, so that the light source can be turned over by 90 degrees, and finally the light source is moved to the tail end along the side edge of the aluminum profile above for locking. When the camera and the light source shoot at the side, the aluminum profile above the assembly line can be rotated to the back, so that the interference to the product of the assembly line is avoided.
From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
the vision inspection apparatus of the present invention is adjustably positioned by the position of the image capturing mechanism so that the image capturing mechanism can have a first position connected to the first support 90 and a second position connected to the second support 100, i.e., the image capturing mechanism can be used to capture image information of different portions of the object 80 when in the first and second positions. The second supporting portion 100 is connected to the first supporting portion 90, and a first predetermined included angle is formed between the second supporting portion 100 and the first supporting portion 90. In the image acquisition process, the position of an image acquisition mechanism is adjusted according to the requirements of an acquisition part, so that image information at different positions is acquired. The vision detection device can enable the image acquisition mechanism to be used for acquiring the image information of different parts of the object 80 only by adjusting the connection positions of the image acquisition mechanism, the second support part 100 and the first support part 90, and solves the problem that the vision detection device in the prior art is complex in acquiring the image information of different directions of the object.
It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be capable of being practiced otherwise than as specifically illustrated and described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
