In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0026] The present utility model discloses a battery polarity detection device. Refer to Figure 1 As shown, the battery polarity detection device of this embodiment includes a photographing device 100, a driving device and a calibration device 300. The photographing device 100 is used for photographing a battery. The driving device is connected to the photographing device 100, and the driving device is used for driving the photographing device 100 to move so that the photographing device 100 can photograph batteries of different sizes. The calibration device 300 is located below the photographing device 100, and the calibration device 300 is used for calibrating the position of the photographing device 100. It can be understood that before the battery polarity detection device starts the test work, the photographing device 100 is calibrated by photographing the calibration device 300 to ensure that the photographing device 100 can clearly and accurately photograph images. After the calibration is completed, the battery is transported below the photographing device 100 under the action of a transportation line, and the battery polarity is detected by photographing the image of the battery, avoiding errors caused by manual detection fatigue and reducing labor and saving costs.
[0027] Refer to Figure 3 As shown, the calibration device 300 includes a calibration bracket 310 and a calibration block 320. The calibration bracket 310 is arranged below the photographing device 100. The calibration block 320 is detachably installed on the calibration bracket 310, and a calibration mark 321 is provided on the calibration block 320. It can be understood that the calibration block 320 is detachably installed on the calibration bracket 310. On the one hand, it can ensure that the calibration block 320 is in a fixed position, thus facilitating the photographing device 100 to perform photographing calibration. On the other hand, the calibration block 320 can be replaced according to actual calibration requirements, so as to better meet the calibration needs of the photographing device 100.
[0028] Optionally, the calibration mark 321 includes at least one calibration step 3211 and / or at least one calibration hole 3212. It should be noted that, in some embodiments, the calibration mark 321 on one calibration block 320 only includes the calibration step 3211; in some embodiments, the calibration mark 321 on one calibration block 320 only includes the calibration hole 3212; in some embodiments, the calibration mark 321 on one calibration block 320 includes both the calibration step 3211 and the calibration hole 3212.

[0029] Further optionally, there are multiple calibration steps 3211, and the multiple calibration steps 3211 form a step that gradually rises from the middle to both sides. Thus, the calibration accuracy of the imaging device 100 can be improved through the multiple calibration steps 3211, thereby facilitating the improvement of the accuracy of imaging detection.
[0030] Further optionally, there are multiple calibration holes 3212, and the multiple calibration holes 3212 are located on both sides of the multiple calibration steps 3211. Thus, the calibration accuracy of the imaging device 100 can be improved through the multiple calibration holes 3212, thereby facilitating the improvement of the accuracy of imaging detection.
[0031] Of course, it should be supplemented here that, in other embodiments of the present invention, the specific type of the calibration mark 321 can also be adjusted according to actual needs and is not limited to the foregoing description.

The imaging bracket 110 is connected to the driving device. The imaging camera 130 is detachably mounted on the imaging bracket 110. The imaging light source 120 is adjustably mounted on the imaging bracket 110 in the vertical direction. The imaging light source 120 is located below the imaging camera 130 and is disposed around the lens of the imaging camera 130. It can be understood that by mounting the imaging bracket 110 on the driving device and mounting the imaging light source 120 and the imaging camera 130 on the imaging bracket 110, the position of the imaging light source 120 can be stably adjusted by the driving device, thereby facilitating the improvement of the accuracy of imaging detection.

Thus, during the actual working process, by adjusting the connection between the light source support and the mounting holes at different height positions, the shooting light source 120 can be adjusted in the vertical direction, thereby ensuring the lighting effect of the shooting light source 120 on the battery. Of course, in other embodiments of the present invention, the shooting light source 120 can also be mounted on the shooting support 110 through structures such as buckles, and is not limited to the foregoing manner.
[0035] Reference Figure 1 As shown, the driving device includes a Z-axis driving unit 210, a Y-axis driving unit 220, and an X-axis driving unit 230.

[0036] Optionally, the battery polarity detection device further includes a guiding device 400. The guiding device 400 is arranged in parallel with the X-axis driving unit 230 and is used to guide the movement of the Y-axis driving unit 220 in the X-axis direction. It can be understood that the added guiding device 400 can improve the movement stability of the Y-axis driving unit 220 in the X-axis direction and avoid the phenomenon of the battery polarity detection device tipping over due to unstable center of gravity.
[0037] Further optionally, the guiding device 400 includes a guiding bracket 410, a guiding slide rail 420, and a guiding slider 430. The guiding bracket 410 is arranged in parallel with the X-axis driving unit 230. The guiding slide rail 420 is installed on the guiding bracket 410 and extends in the X-axis direction. The guiding slider 430 is slidably connected to the guiding slide rail 420 and is connected to the Y-axis driving unit 220. It can be understood that during the movement of the X-axis driving unit 230 driving the Y-axis driving unit 220, the sliding of the guiding slider 430 along the guiding slide rail 420 can improve the movement stability of the Y-axis driving unit 220 in the X-axis direction and avoid the phenomenon of the battery polarity detection device tipping over due to unstable center of gravity.

It can be understood that in this embodiment, the Z-axis drive source 212 is a Z-axis drive motor, and the Z-axis transmission assembly 213 includes a Z-axis lead screw and a Z-axis nut. The Z-axis lead screw is connected to the output shaft of the Z-axis drive motor, the Z-axis nut and the Z-axis lead screw form a lead screw-nut pair, and the Z-axis nut is connected to the photographing bracket 110 of the photographing device 100. During the actual working process, the Z-axis drive motor drives the Z-axis lead screw to rotate, and the Z-axis nut can move along the axial direction of the Z-axis lead screw, thereby driving the photographing device 100 to move in the Z-axis direction. The lead screw-nut pair has high movement accuracy and transportation stability. Selecting the lead screw-nut pair for the Z-axis transmission assembly 213 can improve the movement accuracy and transportation stability of the photographing device 100 in the Z-axis direction. In order to improve the control accuracy, a Z-axis position sensor can also be provided on the Z-axis bracket 211 to detect the movement stroke of the photographing device 100. Of course, in other embodiments of the present invention, the Z-axis transmission assembly 213 can also be other structures such as a gear-rack pair, a conveyor belt structure, a chain drive structure, etc., and is not limited to the foregoing description.
[0039] Reference Figure 1 As shown in the figure, the Y-axis drive unit 220 includes a Y-axis bracket 221, a Y-axis drive source 222, and a Y-axis transmission assembly 223. The Y-axis drive source 222 is installed on the Y-axis bracket 221 and is connected to the power input end of the Y-axis transmission assembly 223.

The lead screw-nut pair has high movement accuracy and transportation stability. Selecting the lead screw-nut pair for the Y-axis transmission assembly 223 can improve the movement accuracy and transportation stability of the photographing device 100 in the Y-axis direction. In order to improve the control accuracy, a Y-axis position sensor can also be provided on the Y-axis bracket 221 to detect the movement stroke of the photographing device 100.

The lead screw-nut pair has relatively high movement accuracy and transportation smoothness. Selecting the lead screw-nut pair for the X-axis transmission assembly 233 can improve the movement accuracy and transportation smoothness of the photographing device 100 in the X-axis direction.
