In addition, when the cylindrical battery cells are arranged, the front and rear battery cells are squeezed together, that is, some battery cells are lifted up, resulting in asynchronous transportation and difficulty in being grabbed in the subsequent grabbing process. Or, when unloading, due to inaccurate battery cell arrangement position, the electromagnetic grabbing head may miss the battery cells, which seriously affects the subsequent process.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] like Figure 1 As shown, the utility model proposes a battery cell sorting conveyor line, including a frame 1, on which at least two groups of arranged conveyor belts 2 are provided. The conveyor belt 2 is an existing synchronous belt structure, and its structure is not repeated in this embodiment. In this embodiment, 4 groups of conveyor belts 2 are selected, and of course the number of conveyor belts 2 is not limited. The conveyor belt 2 includes a loading section 3 and a taking section 4. The loading section 3 is used to arrange and convey the battery cells conveyed in the front sequence, and the taking section 4 is at the rear end. The arranged battery cells are magnetically grabbed by an electromagnetic adsorption manipulator (not shown).

[0026] The loading section 3 and the taking section 4 are continuous, and in order to adapt to battery cells of different lengths, a fixed plate 5 is provided on one side of the conveying direction of each conveyor belt 2, and a width adjustment plate 6 is provided on the other side. The fixed plate 5 and the width adjustment plate 6 are respectively long strips of plate bodies. The fixed plate 5 is fixed to the edge of each group of conveyor belts 2, and the width adjustment plate 6 is arranged parallel to the fixed plate 5. The width adjustment plate 6 is connected with an adjustment component, and the adjustment component drives all the width adjustment plates 6 to move synchronously in the width direction of the conveyor belt 2 to adjust the distance between them and the fixed plate 5. Since the conveyor belts 2 are arranged in an array, synchronous adjustment between different synchronous belts is required, so a support frame is provided above the conveyor belt 2, and the support frame includes a plurality of legs 12 The support leg 12 is provided with a frame body 13, which spans the upper part of the conveyor belt 2, and the adjustment component is provided with a linkage plate 14 on the support frame through a slide rail 15. The direction of the slide rail 15 is set across the conveying direction of the conveyor belt 2. A plurality of connecting rods 17 are provided at the lower part of the linkage plate 14. The connecting rods 17 are fixedly connected to the width adjustment plate 6. An adjustment cylinder 16 is connected to the linkage plate 14, and the adjustment cylinder 16 pushes the linkage plate 14 to move in the width direction of the conveyor belt 2. The linkage plate 14 is pushed to move on the slide rail 15 by the adjustment cylinder 16, thereby driving the width adjustment plate 6 connected to the lower part of the linkage plate 14 close to or away from the fixed plate 5 to adapt to the transportation of battery cells of different lengths.

[0027] In addition, it should be noted that since this conveyor line conveys cylindrical battery cells, when the cylindrical battery cells are conveyed flat, when the arranged battery cells are squeezed, some of the battery cells will be pushed upward, so a pressing device is provided on the upper part of the loading section 3, and the pressing device includes a pressing plate 18 located above each conveyor belt 2, and the end of the pressing plate 18 is provided with an upward flip-up portion, and the pressing plate 18 is fixed to the bottom of the support frame through a connecting frame 19. The connecting frame 19 is a rectangular structure and is fixedly connected to the lower part of the support frame. The distance between the pressing plate 18 and the conveyor belt 2 is slightly larger than the diameter of the battery cell, which can effectively prevent the battery cell from warping.

[0028] When the battery cells in the feeding section 3 gradually move to the retrieving section 4, when there are 6 groups of battery cells in a row, they are pressed, adsorbed and grabbed by the magnetic manipulator. In order to prevent the battery cells from moving on the retrieving section 4 and causing the magnetic manipulator to fail to completely press and adsorb, a magnetic manipulator is installed on both sides of each conveyor belt 2 in the retrieving section 4.

[0029] A first limit baffle 7 and a second limit baffle 8 are movably provided respectively, and a first connecting plate 9 is provided at both ends of the first limit baffle 7. The first connecting plate 9 connects all the first limit baffles 7 to each other, and all the second limit baffles 8 are connected to each other at both ends through a second connecting plate 10. A guide device is connected to the first connecting plate 9 and the second connecting plate 10, and the guide device is used to ensure that the first limit baffle 7 or the second limit baffle 8 moves synchronously. A pushing cylinder 11 is connected to any first limit baffle 7 and a second limit baffle 8. The guide device can be set to 2 groups, which are respectively located at the upper part and the end of the material taking section 4. The guide device includes a stand 20 fixed on both sides of the frame 1. The two sides here refer to the two sides of the transmission direction of the conveyor belt 2. A guide rod 21 is fixed between the stand 20, and the guide rod 21 is provided with two A guide block group 22 is formed, and the guide block group 22 is respectively connected to the first connecting plate 9 and the second connecting plate 10. Since the conveyor belt 2 is relatively long, a guide rod 21 is provided to ensure the synchronization of the forward and backward movement of the first limit baffle 7 and the second limit baffle 8 during lateral movement. The first limit baffle 7 and the second limit baffle 8 located at the edge are respectively connected with a pushing cylinder 11. When in use, after 6 groups of battery cells are arranged on the conveyor belt 2, the first limit baffle 7 and the second limit baffle 8 are respectively pushed by the pushing cylinder 11, which can move along the guide rod 21 of the guide device so that they can press the two ends of the battery cell respectively. After the battery can be pressed and positioned, the magnetic point manipulator presses down to better press the battery cell and achieve adsorption. After ensuring that all are adsorbed, the first limit baffle 7 and the second limit baffle 8 are moved, separated from the two ends of the battery cell respectively, and the battery cell is taken away.

[0030] In addition, in order to ensure the accuracy of the number of battery cells in the material taking section 4, a plurality of beam sensors 23 are provided at the connection between the loading section 3 and the material taking section 4. The beam sensors 23 are used to sense whether the battery cells are in place.
