The image acquisition device 100 provided by the embodiment of the utility model can be used for acquiring the image of the image surface to be acquired of the battery. The image capturing device 100 may include at least two image capturing units 110. The image capturing unit 110 may be disposed above the carrying mechanism 200 for carrying the battery. The carrying mechanism 200 may be configured to carry the battery with the image surface to be collected parallel to the plane of the carrying mechanism 200 and facing the carrying mechanism 200. At least two image capturing units 110 may be disposed above the carrying mechanism 200 and may be configured to respectively capture images corresponding to the image areas to be captured. The combination of the corresponding image areas to be acquired may include an image plane to be acquired.
The image acquisition unit 110 may be a camera. The number of which may be two or more than two. The image acquisition units 110 may or may not be located in the same plane. Taking cameras as an example, the lens orientations of the cameras may be parallel; the lenses may not be parallel, but all the lenses face the battery, and the lenses of the cameras face different image acquisition areas on the battery.
The image surface to be acquired of the battery can be the bottom of the battery or other parts of the battery. The image surface to be acquired may be composed of a plurality of image areas to be acquired. Each image area to be acquired is acquired by a corresponding image acquisition unit 110.

With continued reference to fig. 1, in some alternative embodiments, the image acquisition apparatus 100 may include two image acquisition units 110. The carrying mechanism 200 may have a length direction and a width direction parallel to the plane in which it lies, and a mechanism surface facing the battery. The mechanism surface may include a first region and a second region equally divided in a length direction or a width direction. The two image acquisition units 110 may be disposed at the geometric centers of the first region and the second region, respectively.
The surface of the mechanism may be rectangular or square, and the first region and the second region may be two regions equally divided from left to right or two regions equally divided from top to bottom. The geometric centers of the first region and the second region may be their centers or centers of gravity, respectively, and the like.
In the implementation process, the two image acquisition units 110 are respectively arranged at the geometric centers of the two equally divided areas on the surface of the mechanism, so that the two image acquisition units 110 respectively acquire the images of the image area to be acquired corresponding to the first area and the second area, the visual field of the image acquisition device 100 is enlarged, and the manufacturing cost of the image acquisition device 100 is reduced.

The implementation process is realized by a wide-angle lens camera with extremely short focal length and a visual angle of approximately or equal to 180 degrees. The fisheye camera has a larger image capture field of view than other cameras. Therefore, by adopting the fisheye camera as the image-capturing unit 110, the field of view of the image-capturing device 100 is further improved, thereby further reducing the influence of the accuracy of judging and identifying the defects of the battery.
With continued reference to fig. 1, in some alternative embodiments, the carrying mechanism 200 may include a mechanism surface facing the battery. The image acquisition device 100 may further comprise at least two strip light sources 120. The strip light source 120 may be disposed on a surface of the mechanism and may be configured to project light toward the battery.
In the implementation process, the strip-shaped light source 120 is adopted to project light to the battery, so that the brightness of the image surface to be collected of the battery is more uniform, the definition of the image collected by the image collecting device 100 is further improved, and finally the accuracy of judging and identifying the defects of the battery is improved. In addition, the strip-shaped light source 120 is directly arranged on the surface of the bearing mechanism 200, so that a bracket which is independently manufactured and used for supporting the light source is omitted, the cost of the image acquisition device 100 is further reduced, and the installation space on the bearing mechanism 200 is also saved.
With continued reference to fig. 1, in some alternative embodiments, the strip light source 120 may comprise a light emitting diode flexible light strip. The carrier 200 may have a first mounting region and a second mounting region. The first mounting area may be provided thereon with a carrier member 210 other than the image capturing unit 110 and the strip light source 120. The led flexible light strip may be positioned in the second mounting area.
The carrier element 210 may be an electronic element or a mechanical component carrying the relevant function on the mechanism 200. All of the areas where the carrier elements 210 are mounted may be referred to as a first mounting area. The area of the carrier 200 other than the first mounting area may be used as the second mounting area. A light emitting diode flexible light strip (flexible LED light strip) may be disposed at the second mounting region. That is, the led flexible strip may be disposed in the gap between the carrier elements 210 on the carrier 200.
In the implementation process, the light source setting flexibility in the image capturing device 100 is improved by adopting the light emitting diode flexible light strip as the strip-shaped light source 120 and setting the strip-shaped light strip in the gap between the bearing elements 210 of the bearing mechanism 200. And the flexible light-emitting diode strip can be arranged in the gap between the bearing elements 210 on the bearing mechanism 200, the inherent layout of the bearing elements 210 on the bearing mechanism 200 is not required to be changed, and the arrangement position of the strip-shaped light source 120 is not required to be considered in the stage of designing the bearing elements 210 on the bearing mechanism 200.
With continued reference to fig. 1, in some alternative embodiments, the carrying mechanism 200 may have a length direction and a width direction parallel to a plane thereof. The image acquisition units 110 may be distributed along a first direction. The image acquisition device 100 may include two strip light sources 120. The length direction of the strip light source 120 may be parallel to the first direction. The first direction may be parallel to one of the length direction and the width direction of the carrying mechanism 200. The strip light sources 120 may be arranged along the other of the length direction and the width direction. The image acquisition unit 110 may be located between two bar-shaped light sources 120.
The image capturing units 110 are exemplarily arranged along the length direction of the carrying mechanism 200. Then, each of the strip-shaped light sources 120 may be disposed along the length direction, and the arrangement direction of the strip-shaped light sources 120 may be parallel to the width direction of the carrying mechanism 200.
In the implementation process, only two strip-shaped light sources 120 are adopted and are arranged in the mode, so that the quantity of the strip-shaped light sources 120 is saved on the basis of improving the brightness and brightness uniformity of the image surface to be acquired of the battery.
With continued reference to fig. 1, in some alternative embodiments, the carrying mechanism 200 may have an bisecting axis that trisects its length in the length direction or width direction. The strip light sources 120 may be respectively located on the bisecting axes.
In the implementation process, the strip-shaped light source 120 is arranged on the bisecting axis of the bearing mechanism 200, so that the brightness uniformity of the image surface to be collected of the battery is further improved under the condition that the shape and the size of the image surface to be collected of the battery are close to those of the surface of the mechanism of the bearing mechanism 200, and the accuracy of judging and identifying the defects of the battery is further improved.
In some alternative embodiments, the strip light source 120 may be a first distance from the image acquisition unit 110. The first distance may be determined according to the field angle of the image capturing unit 110 and the brightness of the light source.
If the brightness of the strip light source 120 is higher and the field angle of the image acquisition unit 110 is larger, the first distance may be larger; if the brightness of the bar-shaped light source 120 is low and the angle of view of the image capturing unit 110 is small, the first distance may be small. If the brightness of the strip light source 120 is higher and the field angle of the image capturing unit 110 is smaller, the first distance may also be smaller to improve the brightness within the field angle range of the image capturing unit 110; if the brightness of the strip light source 120 is relatively large and the field angle of the image capturing unit 110 is relatively large, the first distance may also be relatively large, so as to improve the brightness uniformity within the field angle range of the image capturing unit 110.
In the implementation process, the first distance between the strip-shaped light source 120 and the image acquisition unit 110 is determined according to the field angle of the image acquisition unit 110 and the brightness of the light source, so that the balance between the brightness and the brightness uniformity of the image surface to be acquired is improved, the definition of the image acquired by the image acquisition device 100 is further improved, and the accuracy of judging and identifying the defects of the battery is further improved.
In some alternative embodiments, the battery may comprise an automotive power battery and the load bearing mechanism 200 may comprise a battery lift platform.
Currently, there are two main approaches to image acquisition of a vehicle's power battery.
One of them is to use only one camera and mount it on the mounting hole reserved for the battery lifting platform. And a light source bracket is arranged on the battery lifting platform, and two strip-shaped light sources 120 are respectively arranged on the light source bracket. In this scheme, at first, only adopt a camera to take a picture to power battery's bottom, can generally lead to unable complete acquisition battery bottom image because of taking the insufficient field of vision, and then can't judge and discern the defect of battery accurately. Then, not only is the cost increased, but also the installation space on the carrying mechanism 200 is additionally occupied by configuring the light source bracket outside the light source. Finally, the rack may interfere with the battery transport mechanism or the like due to the additional occupation of the installation space on the carrying mechanism 200.
The other is that two 3D cameras are arranged at the buffer position of the feed battery which is detached from the vehicle, and the battery is photographed for a plurality of times in the process of being conveyed to the buffer position from the battery lifting platform so as to splice and obtain a complete battery image. In this scheme, firstly, the power battery is detached and photographed, which usually results in the problem that the power battery is damaged without legal responsibility. Then, because the shooting visual field of the 3D camera is smaller, the whole battery image is obtained by shooting for many times in the power battery conveying process, the image acquisition time is prolonged, and the judging and identifying efficiency of the defects of the battery is reduced. Finally, the 3D camera is expensive, thereby increasing the cost of the image capturing device 100.
In the implementation process, the image acquisition device 100 is applied to image acquisition of the power battery, so that the field of view of image acquisition of the power battery is enlarged, and the accuracy and the efficiency of judging and identifying the defects of the battery are improved. The cost of the image capture device 100 is reduced, as well as the probability of failure to determine responsibility for the problematic power cell.
Based on the same conception, embodiments of the present utility model also provide a battery replacing apparatus, which may include the image capturing device 100 and the carrying mechanism 200 as described in the embodiments of the image capturing device 100.
The battery replacing apparatus provided in the embodiment of the present utility model has the same advantages as those of the image capturing device 100 described in the embodiment of the image capturing device 100, and will not be described herein.
In summary, according to the image capturing device 100 and the battery replacing apparatus provided in the embodiments of the present utility model, the at least two image capturing units 110 correspondingly capture the images of the different image areas to be captured on the image surface to be captured, so that the field of view of the image capturing device 100 is enlarged, and the influence on the accuracy of determining and identifying the defects of the battery is reduced. In addition, the LED flexible lamp strip and the fish-eye camera are adopted, so that the accuracy of judging and identifying the defects of the battery is improved. Especially, the image acquisition device 100 is applied to image acquisition of the power battery, so that the field of view of image acquisition of the power battery is enlarged, and the accuracy and the efficiency of judging and identifying the defects of the battery are improved. The cost of the image capture device 100 is reduced, as well as the probability of failure to determine responsibility for the problematic power cell.
