The picture of the item 5 is reflected into the plurality of cameras 2.

Figure 3 is a side elevational view showing the battery structure of the battery detected by the detecting means in the embodiment of the present invention. Referring to FIG. 3, a battery 5 according to an embodiment of the present invention includes a casing 51. The casing 51 has a plurality of partitions 53. The plurality of partitions 53 separate the plurality of positive plates 55 and the plurality of negative plates 57, and the plurality of positive electrodes Each of the plates 55 has an ear root structure 551, and each of the plurality of negative electrode plates 57 has an ear root structure 571, wherein a bus bar 59 can merge the plurality of ear root structures 551 and the plurality of ear root structures 571 together. Further, although the side view of the battery 5 in FIG. 3 shows only one set of bus bars 59, it should be understood that one battery 5 includes a plurality of bus bars 59.

4a is a schematic view for explaining a normal welded structure of a plurality of ear root structures and bus bars in an embodiment of the present invention. Before referring to Fig. 4a, it should be understood that in order to clearly show the welded structure, only the elements associated with the welded structure are shown in Fig. 4a, and other unrelated elements are not shown in the figures. Referring to FIG. 4a, in the normal soldering structure of the battery 5, the plurality of ear root structures 551 of the plurality of positive electrode plates 55 and the plurality of ear root structures 571 of the plurality of negative electrode plates 57 are connected to the bus bar 59 by a plurality of welded structures 511 to form a pole. group. In an embodiment of the invention, the complex reflecting means 4 reflects the area picture 514 in the battery 5 to the plurality of cameras 2. In other words, the screen acquired by the plurality of cameras 2 and transmitted to the computer device is the area screen 514.

Figure 4b is a schematic diagram for explaining the judgment made by the computer device in the embodiment of the present invention after acquiring the area picture in Figure 4a. Referring to FIG. 4b, in an embodiment of the present invention, when the complex reflection device 4 reflects the area image 514 to the plurality of cameras 2, the plurality of cameras 2 transmits the area picture 514 to the computer device electrically connected to the plurality of cameras 2, The computer device determines the state of the plurality of batteries 5 by the area screen 514, that is, whether or not there is a soldering failure in the area screen 514.

In detail, after the computer device receives the area screen 514, the computer device automatically generates a position correction line 516 and a detection area 518 based on the area screen 514, and the position correction line 516 is used for correction of the horizontal position to detect The position of the lowermost edge of the welded structure 511; the detection area 518 is a binarized window, and the position of the detection area 518 is adjusted based on the position of the position correction line 516. Taking FIG. 4b as an example, when the computer device automatically generates a position correction line 516 based on the area screen 514, the computer device automatically generates a detection area at a predetermined distance from the position correction line 516 based on the position of the position correction line 516. 518, wherein the predetermined distance is a value that has been preset in the computer device. In other words, once the position correction line 516 changes according to the position of the lowermost edge of the welded structure 511, since the detection area 518 is automatically generated at a predetermined distance from the position correction line 516, the position of the detection area 518 also changes. . Therefore, the position of the detection area 518 can be considered to be automatically adjusted based on the position of the position correction line 516.

The computer device determines that the computer device automatically determines whether a white area appears in the detection area 518. If a white area appears in the detection area 518, it is a poor soldering, and a white area refers to an unwelded area. As can be seen from FIG. 4b, no white area appears in the detection area 518, so the computer device determines that the state of the battery 5 is acceptable.

Before referring to Figure 5a, it should be understood that in order to clearly indicate the welded structure, Only the components required for soldering are shown in Figure 5a, and other unrelated components are not shown. Referring to FIG. 5a, if the welded structure of the battery 5 is abnormal, the plurality of welded structures 511 are welded to the wrong position, and the plurality of welded structures 511 cannot effectively connect the plurality of ear root structures 551 and the plurality of ear root structures 571 to the bus bar 59. Similarly, in an embodiment of the invention, the complex reflecting means 4 reflects the area picture 514 in the battery 5 to the plurality of cameras 2. In other words, the screen acquired by the plurality of cameras 2 and transmitted to the computer device is the area screen 514.

Figure 5b is a schematic diagram for explaining the judgment made by the computer device in the embodiment of the present invention after acquiring the area picture in Figure 5a. Referring to FIG. 5b, in an embodiment of the present invention, when the complex reflection device 4 reflects the area image 514 to the plurality of cameras 2, the plurality of cameras 2 transmits the area picture 514 to the computer device electrically connected to the plurality of cameras 2, The computer device determines the state of the plurality of batteries 5 by the area screen 514, that is, whether or not there is a soldering failure in the area screen 514.

The manner in which the computer device determines whether or not there is a weld defect in the area screen 514 has been described above, and therefore will not be described again. This paragraph directly explains the case where the judgment is unqualified. As can be seen from FIG. 5b, when the position of the plurality of solder structures 511 is wrong, a white area 520 appears in the detection area 518, indicating that the plurality of ear root structures 551 and the plurality of ear root structures 571 cannot be effectively connected to the bus bar 59. Therefore, the computer device determines that the state of the battery 5 is unacceptable.

FIG. 6 is a schematic diagram for explaining a picture actually obtained by a computer device according to an embodiment of the present invention by a plurality of cameras.

When the computer device does not detect any white areas in the complex detection area 518 in the plurality of area screens 514, the computer device determines that the soldering status of the battery 5 is acceptable.

FIG. 8 is a schematic diagram for explaining a state in which a computer device according to an embodiment of the present invention judges that a plurality of items to be tested are unqualified by a plurality of area pictures. Referring to FIG. 8, in the screen 64 displayed on the display of the computer device, when the computer device detects the white area 520 in the plurality of detection areas 518 of the plurality of area screens 514, the computer device determines that the welding state of the battery 5 is Not qualified. It will be appreciated that when the computer device does not receive the zone screen 514, the determination action will not be performed.
