[0047] In the prior art, the assembly equipment is generally arranged on a conveyor chain, and a manipulator grabs the battery cells 3 in the loading tray and puts them on the conveyor chain, and the conveyor chain transports them to the assembly equipment for assembly, and the battery cells 3 are generally placed on the jig 2 during transportation to avoid scratches on the battery cells 3; however, there are generally empty materials in the loading tray, that is, there are no battery cells 3 in the placement slots in the loading tray, and then when the manipulator grabs the battery cells 3 and places them on the jig 2 of the conveyor chain, there are empty materials on the jig 2, and the empty jig 2 enters the assembly equipment, which not only leads to low assembly efficiency, but also causes malfunctions to the assembly equipment; generally, for the empty jig 2 on the conveyor chain, a replenishing manipulator can be added to replenish the empty jig 2, but this method not only requires the addition of a manipulator, but also requires the addition of detection equipment and replenishing stations, etc., which increases the cost of assembly; and the number of replenished battery cells 3 is limited and needs to be replenished at any time, which also increases labor costs.

[0048] In view of the shortcomings of the prior art, this embodiment provides a sorting mechanism for cylindrical cells, which can be specifically referred to as follows:

[0049] As attached Figure 1 and attached Figure 2 As shown, a sorting mechanism for cylindrical battery cells includes an annular conveyor chain 1, a feeding conveyor chain 4, a material dividing assembly 5, a first positioning assembly 6 and a second positioning assembly 7. A plurality of jigs 2 are arranged on the annular conveyor chain 1. The plurality of jigs 2 are cyclically moved along with the action of the annular conveyor chain 1. The jigs 2 are used to hold the battery cells 3. A first connecting position 11 and a second connecting position 12 are arranged on one side of the annular conveyor chain 1. The first connecting position 11 and the second connecting position 12 are located on the same side, and the direction from the first connecting position 11 to the second connecting position 12 is the rotation direction of the annular conveyor chain 1. The feeding conveyor chain 4 is arranged on the side of the annular conveyor chain 1 where the first connecting position 11 is opened. A third connection position 41 and a fourth connection position 42 are provided on one side of the conveyor chain 4 close to the circular conveyor chain 1, the first connection position 11 is connected to the third connection position 41, and the second connection position 12 is connected to the fourth connection position 42, so that the jig 2 can be moved on the circular conveyor chain 1 and the unloading conveyor chain 4 to facilitate material separation; the material separation component 5 is provided at the position where the first connection position 11 of the circular conveyor chain 1 is connected to the third connection position 41 of the unloading conveyor chain 4, and the jig 2 carrying the battery cell 3 can be separated to the unloading conveyor chain 4 through the separation component to facilitate unloading, while the jig 2 without the battery cell 3 remains on the circular conveyor chain 1 for recycling;

[0050] By setting up an annular conveyor chain 1 and a feeding conveyor chain 4, and setting a material dividing component 5 therebetween, the jig 2 with the battery cells 3 can be separated onto the feeding conveyor chain 4, and the jig 2 without the battery cells 3 can be circulated along the annular conveyor chain 1, so that the battery cells 3 are arranged in sequence to avoid empty materials, and then the battery cells 3 are grasped and placed on the conveyor chain of the assembly equipment with the help of a robot, thereby improving the assembly efficiency of the battery cells 3 and avoiding malfunctions of the assembly equipment caused by empty materials. Moreover, compared with the method of adding a feeding robot for feeding in the prior art, the structure of the present application is simple and the cost is low, and there is no need to set up an inspection station and inspection equipment, and there is no need for manual feeding operations.

[0051] Specifically, an upper manipulator is provided on the side of the circular conveyor chain 1 away from the unloading conveyor chain 4, and a lower manipulator is provided on the side of the unloading conveyor chain 4 away from the circular conveyor chain 1. The upper manipulator is used to place the battery cells 3 in the loading tray into the jig 2 on the circular conveyor chain 1, and then multiple jigs 2 pass through the dividing assembly 5 to divide the jig 2 carrying the battery cells 3 onto the unloading conveyor chain 4, and then the lower manipulator grabs the neatly arranged battery cells 3 and moves them to the conveyor chain of the assembly equipment, thereby avoiding the situation of empty materials on the conveyor chain from loading to the assembly equipment; and the present application arranges a sorting mechanism before the manipulator loads the material, so that the jigs 2 carrying the battery cells 3 can be arranged in sequence, and when the lower manipulator loads the material to the conveyor chain of the assembly equipment, the grabbing position in the lower manipulator will grab the battery cells 3, thereby avoiding the situation of the lower manipulator having empty materials, effectively improving the assembly efficiency of the battery cells 3 and avoiding the situation of assembly equipment failure caused by empty materials.

[0052] In this embodiment, the upper manipulator and the lower manipulator are both existing technologies and are not shown in the figure; the loading tray is also existing technology. The loading tray is used for transporting battery cells 3, and a placement groove is provided inside the loading tray. The battery cells 3 are arranged in the placement groove. The placement groove inside the loading tray may have empty materials.

[0053] In this embodiment, the jig 2 is cylindrical, and a receiving groove is provided on the top of the jig 2 . The battery cell 3 is also cylindrical and is placed in the receiving groove and moves with the jig 2 .

[0054] As attached Figure 1 As shown, the sorting mechanism for cylindrical battery cells also includes a first positioning component 6 and a second positioning component 7. The first positioning component 6 is arranged on the ring conveyor chain 1, and is used to position the jig 2, so as to facilitate the upper manipulator to place the battery cells 3 in the loading tray on the jig 2 of the ring conveyor chain 1; the second positioning component 7 is arranged on the unloading conveyor chain 4, and is used to position the battery cells 3 after sorting, so as to facilitate the lower manipulator to take away the sequentially arranged battery cells 3 and place them on the conveyor chain of the assembly equipment.

[0055] The right side of the circular conveyor chain 1 is the loading position, the left side of the circular conveyor chain 1 is the dividing position, the left side of the circular conveyor chain 1 is connected to the unloading conveyor chain 4, and the first positioning component 6 is arranged on the right side of the circular conveyor chain 1, for positioning the jig 2 at the loading position of the circular conveyor chain 1, so as to facilitate the upper robot to load; the second positioning component 7 is arranged on the side of the unloading conveyor chain 4 away from the circular conveyor chain 1, for positioning the jig 2 carrying the battery cell 3 after dividing, that is, to position the battery cell 3, so as to facilitate the lower robot to take the material.

[0056] In one embodiment of the present application, as shown in the attached Figure 2As shown, the material distribution component 5 includes a first baffle 51 and a second baffle 52. The first baffle 51 is arranged on the circular conveyor chain 1, and the width of the first baffle 51 gradually increases along the rotation direction of the circular conveyor chain 1, thereby providing a guide for the battery cell 3. The second baffle 52 is arranged on the unloading conveyor chain 4, and the first baffle 51 and the second baffle 52 are arranged opposite to each other, and the width of the second baffle 52 gradually decreases along the rotation direction of the circular conveyor chain 1, thereby corresponding to the shape of the first baffle 51; the first baffle 51 and the second baffle 52 are opposite to each other. The two sides are arranged at intervals, and the two sides facing each other of the first baffle 51 and the second baffle 52 are both inclined, so as to form a guide channel between the two, and one end opening of the guide channel is located on the circular conveyor chain 1, and the other end opening is located on the unloading conveyor chain 4; by setting the two openings of the guide channel on the two conveyor chains respectively, under the action of the circular conveyor chain 1, the jig 2 carrying the battery cell 3 will enter the guide channel and be guided to the unloading conveyor chain 4, while the jig 2 not carrying the battery cell 3 will continue to move in a cycle with the action of the circular conveyor belt.

[0057] In this embodiment, the first baffle 51 and the second baffle 52 are located at the top of the jig 2, that is, the jig 2 does not contact the first baffle 51 and the second baffle 52; the upper surfaces of the first baffle 51 and the second baffle 52 are lower than the upper surface of the battery cell 3, and when the annular conveyor chain 1 drives the jig 2 carrying the battery cell 3 to move to the position of the material distribution component 5, the battery cell 3 passes through one end opening of the guide channel, and under the action of the guide channel, the battery cell 3 drives the jig 2 to change the moving direction, and under the continuous action of the annular conveyor chain 1 and the unloading conveyor chain 4, moves to the other end opening of the guide channel, and moves to the unloading conveyor chain 4 until it moves to the position of the second positioning component 7 and is positioned by the second positioning component 7; at the same time, the jig 2 without the battery cell 3 is located at the bottom of the first baffle 51 and the second baffle 52, and will continue to move in a cycle with the action of the annular conveyor chain 1 without changing its moving direction.

[0058] By arranging the first baffle plate 51 and the second baffle plate 52 between the upper surface of the jig 2 and the upper surface of the battery cell 3, and providing a guide channel between the first baffle plate 51 and the second baffle plate 52, only the jig 2 carrying the battery cell 3 can be guided and its moving direction can be changed to achieve the function of material separation. The material separation structure of the present application is not only simple, but also does not require manual control and supervision, and can perform the material separation work automatically.

[0059] In this embodiment, both sides of the first baffle 51 and the second baffle 52 facing each other are arc-shaped surfaces, and the two arc-shaped surfaces are symmetrical to each other to ensure that the spacing in the guide channel is the same; the arc-shaped surfaces on both sides of the opening of the guide channel close to the annular conveyor chain 1 have a smaller curvature, and the arc-shaped surfaces on both sides of the opening of the guide channel close to the unloading conveyor chain 4 have a larger curvature, so that the battery cells 3 and the jig 2 can be guided to the unloading conveyor chain 4 by a small curvature change, and then the battery cells 3 and the jig 2 can be completely moved to the unloading conveyor chain 4 by a larger curvature, so as to facilitate the unloading conveyor chain 4 to move the jig 2 carrying the battery cells 3 to the position of the second positioning component 7.

[0060] In this embodiment, guide wheels are rotatably arranged on the arcuate surfaces of the first baffle plate 51 and the second baffle plate 52; during the material distribution process, in order to avoid the friction between the outer surface of the battery cell 3 and the arcuate surfaces of the first baffle plate 51 and the second baffle plate 52, guide wheels are arranged on the arcuate surfaces on the opposite sides of the first baffle plate 51 and the second baffle plate 52, and the guide wheels protrude from the arcuate surfaces. After the guide wheels are arranged, the spacing between the guide channels can be adjusted to allow the battery cell 3 to pass through; by arranging the guide wheels, the outer surface of the battery cell 3 can be in point contact with the guide wheels, thereby reducing the friction between the outer surface of the battery cell 3 and the inside of the guide channel.

[0061] Furthermore, a rubber film is provided on the outer surface of the guide wheel, which can effectively prevent the outer surface of the battery cell 3 from being damaged by friction or being scratched by the guide wheel.

[0062] As shown in the attached figure, Figure 3As shown, the sorting mechanism of the cylindrical battery cell also includes a first annular guide bar 13, a second annular guide bar 14 and an arched guide bar 43; the annular conveyor chain 1 and the unloading conveyor chain 4 are both prior art, the annular conveyor chain 1 includes an inner ring and an outer ring, the annular conveyor chain 1 rotates around two turntables, and the two turntables are located inside the inner ring of the annular conveyor chain 1, the first annular guide bar 13 is located at the edge of the inner ring of the annular conveyor chain 1, provides a guide for the jig 2, and also prevents the jig 2 from detaching from the chain plate surface of the annular conveyor chain 1; the outer ring edge of the annular conveyor chain 1 is provided with a second annular guide bar 14, the second annular guide bar 14 cooperates with the first annular guide bar 13, so that the jig 2 moves between them; the second annular A connecting port is provided on the side of the guide bar 14 close to the unloading conveyor chain 4, that is, an opening is cut out on one side of the second annular guide bar 14; an arched guide bar 43 is provided at the connecting port of the second annular guide bar 14, and the two ends of the arched guide bar 43 are respectively connected to the two ends of the connecting port of the second annular guide bar 14, so that the second annular guide bar 14 cooperates with the arched guide bar 43 to form a closed-loop guide bar; and one side of the arched guide bar 43 is located at the edge of the unloading conveyor chain 4, that is, the arched guide bar 43 wraps the unloading conveyor chain 4, and is arc-shaped at both ends of the arched guide bar 43, so as to facilitate guiding the jig 2 into the unloading conveyor chain 4, or to facilitate guiding the jig 2 into the annular conveyor chain 1 after the lower robot grabs the battery cell 3.

[0063] Specifically, the battery cells 3 in the loading tray are placed into the jig 2 through the cooperation of the first positioning component 6 and the upper manipulator. The jig 2 moves to the position of the dividing component 5 under the action of the circular conveyor chain 1. The dividing component 5 divides the jig 2 carrying the battery cells 3 onto the unloading conveyor chain 4. At the position of the dividing component 5, the bow-shaped guide bar 43 is arc-shaped, which is also convenient for guiding the jig 2 to enter the unloading conveyor chain 4. After the jig 2 carrying the battery cells 3 enters the unloading conveyor chain 4, it is positioned by the second positioning component 7, and the lower manipulator grabs the battery cells 3. After the battery cells 3 are grabbed, the jig 2 moves with the unloading conveyor chain 4 to the arc position of the bow-shaped guide bar 43, and under the action of its arc, moves to the circular conveyor chain 1 to continue carrying the battery cells 3 for sorting.

[0064] Furthermore, the upper surfaces of the second annular guide bar 14 and the first annular guide bar 13 are lower than the upper surface of the jig 2 , thereby facilitating the guiding and limiting of the jig 2 .

[0065] In this embodiment, a third baffle 8 is arranged between the annular conveyor chain 1 and the unloading conveyor chain 4, and the two ends of the third baffle 8 are spaced apart from the arched guide bar 43, so as to leave an opening for the jig 2 to enter and move out between the third baffle 8 and the arched guide bar 43; at the same time, the third baffle 8 also prevents empty jigs 2 or jigs 2 loaded with battery cells 3 from flowing into each other.

[0066] In one embodiment of the present application, as shown in the attached Figure 4 As shown, the first positioning assembly 6 includes a first gear cylinder 61, a first positioning cylinder 62 and a second gear cylinder 64. The first gear cylinder 61 is arranged on the inner side of the endless conveyor chain 1 and is located at the inner ring position of the endless conveyor chain 1.

A second gear cylinder 64 is also provided at the inner ring position of the annular conveyor chain 1. The second gear cylinder 64 is located on the side of the first positioning block 63 away from the first gear cylinder 61. A conical block 9 is also provided at the protruding end of the second gear cylinder 64, which is used to block the fixture 2 on one side of the first positioning block 63 to avoid interference between the subsequent fixture 2 and the fixture 2 cooperating with the first positioning block 63.

[0067] In this embodiment, the first positioning assembly 6 also includes a second positioning cylinder 65 and a third gear cylinder 67. The second positioning cylinder 65 is arranged on the inner side of the circular conveyor chain 1 and is located on the side of the second gear cylinder 64 away from the first positioning cylinder 62.
