[0025] like Figures 1 to 3 As shown, the battery cell test clamping and flipping mechanism of the present invention includes: a test frame 1, the test frame 1 is provided with a conveying component 2, the conveying component 2 is arranged along the length direction of the test frame 1, and the conveying component 2 is provided with a tray 3; a visual inspection structure 4, the visual inspection structure 4 is arranged above the test frame 1 and the conveying component 2, and the test frame 1 has a first photographing position and a second photographing position for the visual inspection structure 4 to work in sequence along its length direction; a clamping and flipping component 5, the clamping and flipping component 5 is arranged on the tray 3, for forming a clamping and flipping of the battery cell.

[0026] See also Figure 1 The test frame 1 has a length direction and a width direction. The conveying direction of the conveying assembly 2 is configured along the length direction of the test frame 1. The conveying assembly 2 at least includes a guide rail, a slider configured on the guide rail, a motor configured at the bottom of the test frame 1, a driving pulley connected to the rotating shaft end of the motor, and a driven pulley rotatably mounted on the test frame 1, wherein the driving pulley and the driven pulley are connected by a conveyor belt, and the slider is fixed on the conveyor belt; the motor controls the rotation of the driving pulley, and under the action of the driven pulley and the conveyor belt, the slider can be moved back and forth on the guide rail, thereby realizing the reciprocating movement of the tray 3 configured on the guide rail in the length direction of the test frame 1.

[0027] See also Figure 1 、 Figure 2The test frame 1 is provided with a visual inspection structure 4 directly above the guide rail. Along the length direction of the test frame 1, the visual inspection structure 4 forms a first photographing position and a second photographing position on the test frame 1, wherein the visual inspection structure 4 can photograph the front of the battery cell clamped by the clamping and flipping component 5 at the first photographing position, and can photograph and inspect the back of the battery cell clamped by the clamping and flipping component 5 at the second photographing position; through this setting, it is possible to realize photographic inspection of the front and back sides of the solar cell silicon wafer on the same device, which has the characteristics of high detection efficiency and low production cost, and is practical.

[0028] In one or more embodiments, the visual inspection structure 4 includes a first visual camera 41 and a second visual camera 42 . The first visual camera 41 is configured at a first photographing position of the test frame 1 , and the second visual camera 42 is configured at a second photographing position of the test frame 1 .

[0029] See also Figure 1 The first visual camera 41 is used to photograph the front of the cell, and the second visual camera 42 is used to photograph the back of the cell. Using both the first and second visual cameras 41, 42 to photograph the cell provides high inspection efficiency and accuracy. Furthermore, it should be noted that the first and second visual cameras 41, 42 are sufficiently distant vertically from the gripping and flipping assembly 5 to prevent the cell from contacting the first and second cameras 41, 42 during flipping.

[0030] In one or more embodiments, the clamping and flipping assembly 5 includes at least a support frame 51 arranged on both sides of the conveying assembly 2, a rotating plate 52 rotatably installed on the support frame 51 on the side close to the conveying assembly 2, a gripper 53 arranged on the rotating plate 52, and a driving motor 54 for driving the rotating plate 52 to flip.

[0031] See also Figure 2 、 Figure 3 When clamping the battery cell, the tray 3 is transported to the battery cell loading position by the conveying component 2, and then the battery cell is pushed horizontally into the gripper 53. After the battery cell is clamped by the gripper 53, the battery cell is transported to the first photographing position by the conveying component 2, and the front of the battery cell is photographed and inspected by the first visual camera 41. Thereafter, the battery cell is transported to the second photographing position by the conveying component 2. While transporting the battery cell to the second photographing position, the rotation of the turn plate 52 is controlled by the driving motor 54, and then the gripper 53 and the battery cell on the turn plate 52 are rotated synchronously, so that after the conveying component 2 transports the battery cell to the second photographing position, the battery cell can be flipped over, and then the back of the battery cell is photographed and inspected by the second visual camera 42. Through this setting, the efficiency of photographing and inspecting the battery cell can be further accelerated, which is practical.

[0032] In one or more embodiments, the gripper 53 is a gripper cylinder.

[0033] In one or more embodiments, a lifting cylinder 6 is disposed on the tray 3, and the support frame 51 is disposed at the extended shaft end of the lifting cylinder 6. Figure 2 、 Figure 3 The height of the support frame 51 is increased by the lifting cylinder 6 so that the clamping cylinder can clamp and flip battery cells of more sizes, thereby improving the scope of application of the present application.

[0034] In one or more embodiments, the side of the tray 3 is formed with a stepped layer, and the lifting cylinder 6 is located in the stepped layer. Through this arrangement, the compactness of the overall structure of the device can be improved and the space occupied by the device can be reduced.

[0035] In one or more embodiments, a polished rod is provided on the tray 3, and the polished rod is slidably connected to the support frame 51. The polished rod is not shown in the drawings. By limiting the support frame 51 by the polished rod, the possibility of damage to the jacking cylinder 6 can be reduced, and the service life of the jacking cylinder 6 can be extended.

[0036] In one or more embodiments, a limiting cylinder 7 is disposed on the tray 3 , and a limiting plate 8 that is flush with the tray 3 is disposed at the extended shaft end of the limiting cylinder 7 .

[0037] See also Figure 2 、 Figure 3 The limit plate 8 is located on the upper part of the tray 3 and is parallel to the tray 3. When the clamping cylinder grips the battery cell for flipping, there is a risk that the battery cell may slip off the clamping cylinder due to its heavy weight. When the limit cylinder 7 lifts the limit plate 8 until it is flush with the side of the battery cell after flipping 90°, the side of the battery cell can be limited, preventing the battery cell from falling off the clamping cylinder during the flipping process, thereby improving the safety of the battery cell detection of this application.

[0038] In one or more embodiments, the limiting cylinder 7 is located on the bottom surface of the tray 3. Through this arrangement, the compactness of the structure of the present application can be further improved.

[0039] In addition, the present invention also provides a testing device, which has the battery cell testing clamping and flipping mechanism in any of the above embodiments.

[0040] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
