[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] For easier understanding, see Figure 1 and Figure 2 The utility model provides an embodiment of a battery cell defect detection mechanism, including a rotating platform 1, a follower pressure plate assembly, a pressure plate mounting frame 8 and a detection camera. The rotating platform 1 includes a base, a horizontal rotation drive mechanism and a battery cell placement plate. The horizontal rotation drive mechanism is installed on the base, and the battery cell placement plate is installed on the horizontal rotation drive mechanism. The follower pressure plate assembly includes a mounting plate, a rotating shaft 9, a transmission block 10, a vertical drive mechanism 6 and a pressure plate 2. The mounting plate is installed on the pressure plate mounting frame 8, and the vertical drive mechanism 6 is installed on the mounting plate. The output end of the vertical drive mechanism 6 is equipped with a transmission block 10, one end of the rotating shaft 9 is movably connected to the transmission block 10, and the other end of the rotating shaft 9 is fixedly connected to the top of the pressure plate 2. The detection camera is arranged on one side of the rotating platform 1, and the shooting angle of the detection camera faces the side area of ​​the battery cell 4 on the battery cell placement plate.

[0029] It should be noted that the pressure plate 2 is driven up and down by the vertical drive mechanism 6 to realize that the pressure plate 2 presses the battery cell 4 and moves away from the battery cell 4. The vertical drive mechanism 6 drives the transmission block 10, and the transmission block 10 is movably connected to one end of the rotating shaft 9. The top of the pressure plate 2 is connected to the other end of the rotating shaft 9. Therefore, after pressing the battery cell 4, the pressure plate 2 can rotate with the rotation of the rotating platform 1. The vertical drive mechanism 6 adopts a driving cylinder. Specifically, a rotating member 11 is provided on the transmission block 10, and the rotating member 11 is fixedly connected to the rotating shaft 9. The rotating shaft 9 and the transmission block 10 are movably connected through the rotating member 11. The rotating member 11 is a bearing.

[0030] The working principle of the cell defect detection mechanism provided in the embodiment of the utility model is as follows: a cell 4 (one or more cells stacked) is placed on the cell placement plate of the rotating platform 1, the cell 4 on the cell placement plate is pressed by the pressure plate 2, and then the detection camera is controlled to take a picture of one of the side areas of the cell 4 to detect the defects of the cell 4, and the detection camera has a built-in preset image recognition algorithm to realize defect recognition. After taking a picture of one side area, the cell placement plate is rotated by the rotating platform 1, and the pressure plate 2 presses the cell 4 to rotate, and the other side area of ​​the cell 4 on the cell placement plate is transferred to the detection position of the detection camera, and the other side area of ​​the cell 4 on the cell placement plate is detected for defects, and each rotation is 90 degrees, and the defect detection of all side areas of the cell 4 is completed after three rotations in sequence. The rotating platform 1 and the follower pressure plate assembly are used in conjunction to realize the rotation and transposition of the cell on the cell placement plate, and only one detection camera is needed to complete the defect detection of all side areas of the cell, without setting multiple detection cameras at multiple positions, saving space and reducing costs. It solves the technical problem that the appearance defects of traditional solar cells need to be inspected by multiple inspection cameras at different positions, which not only takes up space but also has high costs.

[0031] At the same time, the battery cell defect detection mechanism provided by the utility model does not require human participation in the entire defect detection process, thereby improving defect detection efficiency and saving labor costs.

[0032] In one embodiment, the detection camera is an edge detection camera 3, and the shooting angle of the edge detection camera 3 faces the side area of ​​the battery cell 4 on the battery cell placement plate. The battery cell 4 (one or more cells stacked) is placed on the battery cell placement plate of the rotating platform 1, and the battery cell 4 on the battery cell placement plate is pressed by the pressure plate 2, and then the edge detection camera 3 is controlled to take a picture of one of the sides of the battery cell 4 to detect the edge collapse of the battery cell 4. The edge detection camera 3 has a built-in preset image recognition algorithm to realize defect recognition. After taking a picture of one side, the battery cell placement plate is rotated by the rotating platform 1, and the pressure plate 2 presses the battery cell 4 to rotate, and the other side of the battery cell 4 on the battery cell placement plate is turned to the detection position of the detection camera, and the other side of the battery cell 4 on the battery cell placement plate is detected for edge collapse. The rotation is 90 degrees each time, and the rotation is completed 3 times in sequence to complete the detection of all edge defects of the battery cell 4.

[0033] In the cell defect detection mechanism, the detection camera is a chamfer detection camera 5, which is installed on the other side of the rotating platform 1, and the shooting angle of the chamfer detection camera 5 faces the chamfer area of ​​the cell 4 on the cell placement plate. The appearance defects of the cell 4 also include chamfer defects. Therefore, in the embodiment of the utility model, the chamfer detection camera 5 is set to perform defect detection on the chamfer of the cell 4, and the chamfer detection camera 5 has a built-in preset image recognition algorithm to realize defect recognition.

[0034] In the cell defect detection mechanism, the detection camera may include an edge detection camera 3 and a chamfer detection camera 5. The chamfer detection camera 5 and the edge detection camera 3 may work separately or simultaneously, that is, when performing a side edge collapse detection on the cell 4, the chamfer detection camera 5 simultaneously performs a defect detection on a chamfer of the cell 4. In this way, the four-side detection and four-chamfer detection of the cell 4 can be completed simultaneously by rotating the rotating platform 1 three times, thereby improving the efficiency of defect detection.

[0035] In one embodiment, the horizontal rotation drive mechanism is a rotation servo motor.

[0036] In one embodiment, the battery cell defect detection mechanism also includes a horizontal moving module 7, which is mounted on the top of the pressure plate mounting frame 8, and the horizontal moving module 7 is fixedly connected to the mounting plate of the follower pressure plate assembly. The horizontal moving module 7 can realize the movement and adjustment of the pressure plate 2 in the horizontal direction. Specifically, the horizontal moving module 7 includes a driving motor, a linear guide, a slider and a support plate, the linear guide is mounted on the mounting frame, the driving motor is electrically connected to the slider, the slider is movably mounted on the linear guide, one end of the support plate is fixedly connected to the slider, and the other end of the support plate is fixedly connected to the mounting plate. The driving motor drives the slider to move on the linear guide, thereby driving the support plate to drive the mounting plate to realize the movement in the horizontal direction, thereby realizing the movement and adjustment of the pressure plate 2 in the horizontal direction.

[0037] In one embodiment, the cell defect detection mechanism further includes a displacement sensor, which is installed on the side of the pressure plate 2 and is used to detect the distance between the pressure plate 2 and the cell 4 on the cell placement plate. The displacement sensor detects the distance between the pressure plate 2 and the cell 4 on the cell placement plate, thereby accurately controlling the descending height of the pressure plate 2 to avoid excessive descending height of the pressure plate 2, which causes excessive pressure on the cell 4 and damages the cell 4.

[0038] In one embodiment, in order to save material cost, the pressure plate 2 is configured as a hollow structure.

[0039] In one embodiment, in order to prevent the pressing plate 2 from causing mechanical damage to the battery cell 4 when pressing the battery cell 4, a buffer layer may be provided at the bottom of the pressing plate 2. Specifically, the buffer layer is a silicone gasket.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
