DETAILED DESCRIPTION

[0028] The following will be described in detail in combination with the accompanying Figures 1-5 The application will be further described in detail.

[0029] The embodiment of the application discloses a gradient battery cell shape detection system. Referring to Figure 1 , the gradient battery cell shape detection system comprises a feeding assembly 1, a measurement assembly 2 and a material turning assembly 3; The feeding assembly 1 comprises a first rack 11, a central rotating shaft 12, a first motor 13 and four material loading tables 14. The central rotating shaft 12 has a central axis which is a first axis and is parallel to a first direction. In the embodiment, the first direction is preferably a vertical direction. The central rotating shaft 12 is rotationally connected to the first rack 11 about the first axis. In order to rotate the central rotating shaft 12, a mounting groove 111 is formed in the bottom of the first rack 11. The first motor 13 is located in the mounting groove 111, and the shell of the first motor 13 is fixedly connected to the first rack 11. The central rotating shaft 12 penetrates the material loading tables 14, and the central rotating shaft 12 is coaxially fixedly connected to the output shaft of the first motor 13. Therefore, the first motor 13 can drive the central rotating shaft 12 to rotate about the first axis. The material loading tables 14 are connected to the central rotating shaft 12, and the four material loading tables 14 are circumferentially and uniformly distributed about the central rotating shaft 12. Specifically, a connecting rod 15 is fixedly connected between the material loading tables 14 and the central rotating shaft 12, so that the material loading tables 14 rotate synchronously with the central rotating shaft 12 about the first axis. In order to facilitate the description of the positions of the four material loading tables 14, there are four stations in the embodiment, which are an upper loading station, a scanning station, a lower loading station and a material turning station arranged in sequence along the circumference of the central rotating shaft 12. When the material loading tables 14 are stationary, each station is respectively provided with one corresponding material loading table 14. The material loading tables 14 at different stations can be subjected to different working procedures. When it is necessary to transport the electrical properties on the material loading tables 14 to the next station, the central rotating shaft 12 is driven by the first motor 13 to rotate along the first rack 11, so that the material loading tables 14 at each station can be synchronously transported to the next station.

[0030] Referring to Figure 1 During the working process, after the battery cell is placed on the material loading table 14, in order to facilitate the turning of the battery cell placed on the material loading table 14, a clamping groove 141 is formed on the side of the material loading table 14 away from the first axis, and the clamping groove 141 is provided in the first direction. After the battery cell is placed on the material loading table 14, one of the outer walls of the battery cell is exposed to the clamping groove 141, so that the battery cell can be clamped from both the upper and lower sides of the battery cell. When the battery cell is placed on the material loading table 14, in order to prevent the battery cell from sliding, an anti-skid layer 142 is arranged on the upper surface of the material loading table 14. In the embodiment, the anti-skid layer 142 is a flexible silica gel layer which is adhered to the upper surface of the material loading table 14 by glue. The placement of the battery cell on the anti-skid layer 142 can prevent the battery cell from sliding on the material loading table 14. The softness of the flexible silica gel layer can also reduce secondary impact on the battery cell, thereby reducing damage to the battery cell.

[0031] Referring to Figure 2The turnover assembly 3 is located at a turnover station and is used for turning over the battery cell placed on the loading table 14; the turnover assembly 3 comprises a second rack 31, a moving seat 32, a second linear driving member 33, a rotating seat 34, a second motor 35 and two clamping members 36; The moving seat 32 is slidingly connected to the second rack 31 along a second axis, and the second linear driving member 33 is connected between the moving seat 32 and the second rack 31; in the embodiment, the second linear driving member 33 is a cylinder, the cylinder body of the second linear driving member 33 is fixedly connected to the second rack 31, the piston rod is fixedly connected to the moving seat 32, the driving direction of the second linear driving member 33 is parallel to the second axis, and the moving seat 32 can be driven to move along the second axis by the second linear driving member 33; The second motor 35 is connected between the rotating seat 34 and the moving seat 32, specifically, the shell of the second motor 35 is fixedly connected to the moving seat 32, the output shaft of the second motor 35 is fixedly connected to the rotating seat 34, the central axis of the output shaft of the second motor 35 coincides with the second axis, and the rotating seat 34 can be driven to rotate around the second axis by the second motor 35; The explanation about the second axis is that the second axis coincides with a diameter of a virtual circle, and the central axis of the virtual circle coincides with the first axis, that is, the rotating seat 34 can be close to or away from the central rotating shaft 12 by moving along the second axis; The clamping members 36 are located on the side of the rotating seat 34 close to the central rotating shaft 12, the two clamping members 36 are spaced apart in the first direction and are slidingly connected to the rotating seat 34 in the first direction respectively, so as to clamp the battery cell on the loading table 14; in order to drive the two clamping members 36 to move in the first direction respectively, two third linear driving members 37 are connected to the rotating seat 34, the third linear driving member 37 is a linear motor with a guide part and a driving part, the guide part of the third linear driving member 37 is fixedly connected to the rotating seat 34, the driving part of the third linear driving member 37 is slidingly connected to the guide part along the length direction of the guide part, the length direction of the guide part is parallel to the third direction, the third direction is perpendicular to the second axis, specifically, since the third linear driving member 37 will rotate with the rotating seat 34, the third direction is adjusted with the rotation of the third linear driving member 37; the driving part of each third linear driving member 37 is fixedly connected to a corresponding clamping member 36, so that the clamping member 36 is driven to move in the third direction by the third linear driving member 37; When the battery cell is transported to the material turning station from the previous station, the battery cell is turned over by the material turning assembly 3. Specifically, the second motor 35 drives the rotating seat 34 to rotate until the third direction is parallel to the first direction, and the clamping piece 36 is moved by the third linear drive 37 to make the battery cell have one clamping piece 36 on each of the upper and lower sides. The clamping piece 36 located below the battery cell can extend into the clamping groove 141. Then, the two clamping plates are close to each other and clamp the battery cell. After clamping the battery cell, the two clamping pieces 36 are synchronously moved upward to drive the battery cell to move upward to a preset height (the preset height is set based on the condition that the battery cell does not interfere with the material loading table 14 during the rotation of the clamping piece 36). Then, the second motor 35 drives the clamping piece 36 and the battery cell to synchronously rotate by 90° or 180°. Then, the clamping piece 36 is transported downward until the battery cell is overlapped on the material loading table 14, so that the turning of the battery cell is completed. Subsequently, the clamping piece 36 is reset to turn the next battery cell. The battery cell has six surfaces in total, four of which are side surfaces, and the other two are plate surfaces. The two plate surfaces are parallel to each other, and the four side surfaces are located around the plate surfaces. When one of the side surfaces of the battery cell is overlapped on the material loading table 14, the battery cell is turned by 90°, so that the next side surface of the battery cell is overlapped on the material loading table 14. When one of the plate surfaces of the battery cell is overlapped on the material loading table 14, the battery cell is turned by 180°, so that the other plate surface of the battery cell is overlapped on the material loading table 14.

When the supporting rod 42 is in the pushing posture, the top of the supporting rod 42 extends above the material loading table 14. When the supporting rod 42 is in the storage posture, the top of the supporting rod 42 is stored in the perforation 143. During operation, the supporting rod 42 pushes the battery cell upward from the position close to the bottom wall of the battery cell to the position close to the center of the battery cell, so that the posture of the battery cell from the plate surface overlapped on the material loading table 14 to the side surface overlapped on the material loading table 14 is adjusted. The connecting seat 41 is connected to the material loading table 14, and the first linear driving member 43 is connected between the top supporting rod 42 and the connecting seat 41, and is used to drive the top supporting rod 42 to adjust between the storage posture and the pushing posture; the first linear driving member 43 is a cylinder, the cylinder body of the first linear driving member 43 is fixedly connected to the connecting seat 41, and the piston rod is fixedly connected to the top supporting rod 42, so as to drive the top supporting rod 42 to move in the first direction.
