They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] Please refer to Figures 1 to 4A battery electrode conveying and testing mechanism includes a first section 111 and a second section 112 arranged sequentially along a first direction X. Both the first section 111 and the second section 112 include vacuum belts. The vacuum surfaces of the first section 111 and the second section 112 are longitudinally opposite each other, forming a transition gap for conveying the electrode. The first section 111 also includes a cavity plate 1112. The vacuum belt of the first section 111 is sleeved on the cavity plate 1112. Light-transmitting support plates 1111 extending outwards are provided on both sides of the cavity plate 1112 in the width direction of the vacuum belt. A light source 1113 is provided below the light-transmitting support plate 1111, and a vision component 1115 is provided above the light-transmitting support plate 1111. Battery electrodes 10 are laid flat on the vacuum surface of the first section 111 and transferred to the vacuum surface of the second section 112 after passing through the transition gap. In this embodiment, optionally, the vacuum surface of the first section 111 is arranged facing upwards, and the vacuum surface of the second section 112 is arranged facing downwards.

[0027] like Figure 1 and Figure 2 As shown, the vacuum belt of the first segment 111 is the first vacuum belt 113a, and the vacuum belt of the second segment 112 is the second vacuum belt 113b.

[0028] The cavity plate 1112 supports the first vacuum belt 113a. At least one support rod 1114 is provided on the side of the cavity plate 1112, and a light-transmitting support plate 1111 is mounted on the support rod 1114. In this embodiment, the upper surface of the light-transmitting support plate 1111 is slightly lower than the vacuum surface of the first section 111. The light-transmitting support plate 1111 supports the battery electrode 10, ensuring that the battery electrode 10 remains flat throughout the first vacuum belt 113a, preventing it from collapsing. Simultaneously, it allows the light source 1113 to shine through the light-transmitting support plate 1111 onto the battery electrode 10, enabling the vision component 1115 to capture and inspect the battery electrode 10. Optionally, the vision component 1115 is a CCD vision inspection component. The battery electrode conveying and testing mechanism here can realize the transfer and testing of battery electrode 10. At the same time, the light-transmitting tray 1111 increases the support area of ​​the first section 111 on the battery electrode 10 in the width direction of the vacuum belt, so that the battery electrode conveying and testing mechanism can be adapted to the processing of more specifications of battery electrode 10.

[0029] like Figure 2 and Figure 3As shown, the first segment 111 also includes an adjustable pressing and moving frame 1116 disposed above the first vacuum belt 113a. The pressing and moving frame 1116 can move closer to or further away from the vacuum surface of the first segment 111 longitudinally. A light-transmitting flat plate 11161 is mounted on the pressing and moving frame 1116. The battery electrode 10 passes through the gap between the light-transmitting support plate 1111 and the light-transmitting flat plate 11161. The light-transmitting flat plate 11161 is located between the light-transmitting support plate 1111 and the vision component 1115. Preferably, the light-transmitting flat plate 11161 is parallel to the light-transmitting support plate 1111. The light-transmitting flat plate 11161, together with the light-transmitting support plate 1111, is used to smooth the battery electrode 10 within the detection range of the vision component 1115. Specifically, it flattens the four corners and tabs of the battery electrode 10, so that the battery electrode 10 within the detection range is laid flat on the first vacuum belt 113a, ensuring that the battery electrode 10 is free of wrinkles, curling, and folding during the photo inspection, thus preventing the vision component 1115 from misjudging.

[0030] In this embodiment, the battery electrode conveying and testing mechanism further includes a first square tube frame (not shown in the figure), the first square tube frame is equipped with a second fixed plate 11162 (not shown in the figure), the downward moving frame 1116 is slidably connected to the second fixed plate 11162 through a slide rail slider assembly, and the cavity plate 1112 is mounted on the second fixed plate 11162. Figure 2 and Figure 3 As shown, the light-transmitting flat plate 11161 and the pressing and moving frame 1116 are detachably connected by screws or bolts. The pressing and moving frame 1116 has several screw holes spaced apart along the width direction of the first vacuum belt 113a for mounting screws or bolts, allowing the mounting position of the light-transmitting flat plate 11161 in the width direction of the first vacuum belt 113a to be adjustable to accommodate battery electrode sheets 10 of different specifications. The pressing and moving frame 1116 is driven by a servo motor or cylinder to adjust its longitudinal height.

[0031] like Figure 2 and Figure 4As shown, the first segment 111 also includes a guide plate 1117 disposed above the first vacuum belt 113a. The guide plate 1117 is inclined relative to the vacuum surface of the first segment 111. In the first direction X, the distance between the downstream end of the guide plate 1117 and the vacuum surface of the first segment 111 is less than the distance between the upstream end of the guide plate 1117 and the vacuum surface of the first segment 111. The battery electrode 10 on the first vacuum belt 113a passes through the gap between the guide plate 1117 and the vacuum surface of the first segment 111. In this embodiment, in the first direction X, an adjusting rod 11171 is rotatably mounted on the support rod 1114 downstream of the pressing moving frame 1116, and the guide plate 1117 is mounted on the adjusting rod 11171. Here, the adjusting rod 11171 can adjust the size of the gap between the guide plate 1117 and the vacuum surface of the first segment 111. The guide plate 1117 here is used to smooth the battery electrode 10 to facilitate subsequent testing, such as by a line scan camera, to prevent the battery electrode 10 from lifting up and causing misjudgment by the line scan camera.

[0032] like Figure 1 As shown, the line scan camera includes a first line scan camera 113c and a second line scan camera 113d. The first line scan camera 113c is located above the first segment 111, and the second line scan camera 113d is located below the second segment 112. It is used to detect the front and back sides of the battery electrode 10. Qualified battery electrode 10 is transported to the stacking segment, while defective products are collected in the second NG mechanism within the second segment 112.

[0033] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
