[0050] Embodiment 1

[0051] The first embodiment of the present application provides a battery cell sorting device, referring to Figure 1 , the device comprises:

[0052] The turning platform 1 is used to carry and fix the material box 100 containing the battery cells, and has a first state of being horizontally arranged and a second state of being vertically arranged;

[0053] A flip driving mechanism 2, used for driving the flip platform 1 to switch between a first state and a second state;

[0054] The flexible clamping mechanism 3 includes a floating blocking member 31; when the flip platform 1 switches between the first state and the second state, the blocking member 31 can be arranged at the opening of the material box 100;

[0055] The sheet sorting mechanism 4 is used for blowing air into the material box 100 .

[0056] Figure 1 is a schematic diagram of the three-dimensional structure of the device when the flip platform 1 is in a first state in which it is horizontally arranged. Figure 2 : is a schematic diagram of the forward structure of the device (the film arrangement mechanism is removed for easy viewing) when the flip platform 1 is between the first state and the second state. Figure 3 is a schematic diagram of the three-dimensional structure of the device when the flip platform 1 is in the second state of being vertically arranged, Figure 4 This is a schematic diagram of the forward structure of the device (excluding the film arrangement mechanism) when the flip platform 1 is in the second state. Figures 1 to 4 , the working process of the above device is as follows:

[0057] Reference Figure 1 In the initial state, the turning platform 1 is in the first state, and the staff loads the material box 100 containing the battery cells onto the turning platform 1;

[0058] Reference Figure 2 Then, the flip driving mechanism 2 drives the flip platform 1 to rotate from the horizontal setting (first state) to the vertical setting (second state). When the flip platform 1 rotates a certain angle but does not completely rotate to the second state, the blocking member 31 moves to the opening of the material box 100 to block the battery cells in the material box 100 to prevent the battery cells from falling.

[0059] Reference Figure 3 , the flip driving mechanism 2 drives the flip platform 1 to continue rotating until the flip platform 1 rotates to a vertical setting (second state). During this process, the battery cells are naturally dropped to the bottom of the material box 100 by utilizing the gravity of the battery cells themselves; at this time, the cell sorting mechanism 4 is aligned with the material box 100 on the flip platform 1;

[0060] Then, the sheet sorting mechanism 4 blows air into the material box 100 through the gaps on the side wall of the material box 100, and the airflow scatters the battery sheets so that each battery sheet can fall to the bottom of the material box 100 under the action of gravity, so that the battery sheets can be neatly arranged;

[0061] After the wafer sorting is completed, the flipping drive mechanism 2 drives the flipping platform 1 to rotate from the vertical setting (second state) to the horizontal setting (first state), and the neatly arranged battery cells fall to the bottom of the material box 100 under the action of gravity; finally, the staff removes the material box 100 where the wafer sorting is completed, waiting for the next wafer sorting.

[0062] The cell sorting device provided by the present application can realize automatic cell sorting, has the advantages of high work efficiency and good cell sorting effect, can reduce the labor intensity of personnel, and can avoid damaging the cell by blowing the cell sorting method, thereby improving the quality of the cell. In addition, during the rotation of the flip platform 1, the floating blocking member 31 can flexibly block the cell in the material box 100, and its position can be adaptively adjusted in a floating manner according to the tilt state of the cell, thereby preventing the cell from falling and not damaging the cell, further reducing the risk of damaging the cell; further, the blocking member 31 can also be slightly adjusted in a floating manner during the air blowing cell sorting process, thereby improving the cell sorting effect.

[0063] In the above structure, the cell sorting mechanism 4 has a pulse blowing function, which can accurately adjust the air pressure and air flow rate, thereby avoiding any damage to the battery cells. In this embodiment, when the flip platform 1 is in a vertical setting (the second state), one edge of the material box 100 is located at the bottom; after the battery cells are sorted, one edge of the battery cell is located at the bottom, and the two adjacent side surfaces of the bottom of the battery cell are respectively against the two side walls of the bottom of the material box 100; when the flip platform 1 is rotated to a horizontal setting (the first state), the battery cells are neatly arranged at a corner of the material box 100.

[0064] Optionally, when the turning platform 1 rotates to an angle less than or equal to 65° with the horizontal plane, the blocking member 31 moves to the opening of the material box 100. In this angle range, the battery cells are not easy to fall out of the opening of the material box 100.

[0065] Continue to refer to Figure 1 The turning platform 1 is provided with a clamping member 11 and a clamping driving source 12 for driving the clamping member 11 to move in a direction close to or away from the material box 100. The clamping member 11 is used to press the material box 100 onto the turning platform 1. In this embodiment, the number of the clamping member 11 and the clamping driving source 12 are both two, and the two clamping members 11 are respectively provided on opposite sides of the turning platform 1, so that the opposite sides of the material box 100 can be clamped and fixed.

[0066] Optionally, the clamping drive source 12 is specifically a cylinder, and the end of the piston rod of the clamping drive source 12 is connected to the clamping member 11, and the clamping or releasing of the material box 100 is achieved by rotating and extending the piston rod of the clamping drive source 12. When the material box 100 needs to be fixed, the piston rod of the clamping drive source 12 rotates and descends, driving the clamping member 11 to rotate above the side wall of the material box 100 and descend to press the material box 100.

[0067] Continue to refer to Figure 1 The battery cell sorting device also includes a support frame 5, on which the flipping drive mechanism 2, the flexible clamping mechanism 3 and the cell sorting mechanism 4 are all mounted. The power output end of the flipping drive mechanism 2 is connected to the flipping platform 1, and the device is formed into a whole through the support frame 5.

[0068] Reference Figure 4 The flip driving mechanism 2 includes a flip driving source 21 and a transmission reduction box 22 . The power output end of the flip driving source 21 is connected to the flip platform 1 through the transmission reduction box 22 .

[0069] The support frame 5 is provided with a first limiting structure 51 and a second limiting structure 52, and a positioning cam 222 is installed on a transmission shaft 221 of the transmission reduction box 22;

[0070] When the flip platform 1 is in the first state, the positioning cam 222 abuts against the first limiting structure 51; the first limiting structure 51 can limit the rotation angle of the flip platform 1, so that the flip platform 1 can be stably in the first state;

[0071] When the flip platform 1 is in the second state, the positioning cam 222 abuts against the second limiting structure 52; the second limiting structure 52 can also limit the rotation angle of the flip platform 1, so that the flip platform 1 can be stably in the second state.

[0072] On the basis of the above structure, both ends of the transmission shaft 221 respectively pass through the transmission reduction box 22 and are respectively equipped with a positioning cam 222; accordingly, the number of the limiting structures is two, and they are respectively arranged at both ends of the transmission shaft 221, corresponding to the two positioning cams 222 one by one.

[0073] Further, Figure 3 and Figure 4 The flip platform 1 is also provided with a support roller 13, which is provided at the bottom of the flip platform 1 in the second state, and is used to support the material box 100 to prevent the material box 100 from falling when the flip platform 1 is in the second state. In this embodiment, the number of the support rollers 13 is two, and the support effect of the material box 100 can be improved by using multiple support rollers 13.

[0074] Continue to refer to Figure 3 , the film sorting mechanism 4 includes at least one air nozzle 41 for blowing air into the material box 100; when the number of the air nozzles 41 is multiple, the air nozzles 41 are distributed along the circumference of the flip platform 1 in the second state. Multiple air nozzles 41 can blow air into the material box 100 from multiple angles, further improving the film sorting effect. In this embodiment, there are four slits on the side wall of the material box 100, and accordingly, the number of the air nozzles 41 is four, and when the flip platform 1 is in the second state, the four air nozzles 41 correspond to the four slits one by one.

[0075] On the basis of the above structure, the cell sorting mechanism 4 further includes at least one nozzle driving source 42, which corresponds to the nozzle 41 one by one, and is used to drive the corresponding nozzle 41 to reciprocate in the horizontal direction. During the process of blowing and sorting cells, the nozzle driving source 42 drives the nozzle 41 to reciprocate in the horizontal direction, thereby effectively sorting the cells.

[0076] Reference Figure 5 , the flexible clamping mechanism 3 also includes:

[0077] Fixed seat 32;

[0078] The blocking driving source 33 is slidably mounted on the fixing seat 32 in a direction approaching or moving away from the flipping platform 1, and is used to drive the blocking member 31 to move in a direction approaching or moving away from the flipping platform 1;

[0079] The elastic member 34 is connected between the fixing seat 32 and the blocking driving source 33 , and is used for providing an elastic force to drive the blocking driving source 33 to approach the flip platform 1 .

[0080] Specifically, the fixed seat 32 is fixedly installed on the support frame 5; the blocking drive source 33 is specifically a cylinder, and the piston rod end of the blocking drive source 33 is connected to the blocking member 31; the elastic member 34 is specifically a spring, which is arranged between the blocking drive source 33 fixed seat 32, and is used to provide an elastic force to drive the blocking drive source 33 close to the flip platform 1.

[0081] The working principle of the flexible clamping mechanism 3 is as follows: Figure 1 In the initial state, the flip platform 1 is set horizontally to block the piston rod of the driving source 33 from retracting; Figure 2 Then, the flip driving mechanism 2 drives the flip platform 1 to rotate from the horizontal setting to the vertical setting. When the flip platform 1 rotates a certain angle, the piston rod of the blocking driving source 33 extends out, driving the blocking member 31 to move to the opening of the material box 100; then, the flip driving mechanism 2 drives the flip platform 1 to continue rotating. In this process, since the blocking driving source 33 is slidably mounted on the fixing seat 32 in the direction close to or away from the flip platform 1, under the action of the elastic member 34, the blocking member 31 can be adaptively adjusted in the horizontal direction according to the flipping degree of the battery cell. The flexible clamping method can avoid damaging the battery cells; then, the cell sorting mechanism 4 blows air into the material box 100 through the gap on the side wall of the material box 100, and the blocking member 31 can adaptively float during the process of blowing and sorting the cells, further avoiding damage to the battery cells; after the cell sorting is completed, the flipping drive mechanism 2 drives the flipping platform 1 to rotate from a vertical setting to a horizontal setting. When the flipping platform 1 rotates to a certain angle (the battery cells will not fall at this angle), the piston rod of the blocking drive source 33 retracts, driving the blocking member 31 away from the material box 100 to avoid hindering the rotation of the flipping platform 1.

[0082] Continue to refer to Figure 5 The flexible clamping mechanism 3 also includes a plurality of guide shafts 37 and a slide seat 39. Both ends of the guide shaft 37 are fixed on the fixed seat 32. The slide seat 39 is slidably arranged on the guide shaft 37. The blocking driving source 33 is mounted on the slide seat 39. The elastic member 34 corresponds to the guide shaft 37 one by one, and the elastic member 34 is sleeved on the corresponding guide shaft 37. Both ends of the elastic member 34 are respectively abutted against the slide seat 39 and the fixed seat 32.

[0083] Furthermore, the flexible clamping mechanism 3 also includes an adjusting bolt 38, which is screwed to one end of the fixing seat 32 away from the elastic member 34, and the end of the adjusting bolt 38 abuts against the slide 39; by rotating the adjusting bolt 38, the distance between the slide 39 and the flip platform 1 can be adjusted to make the blocking member 31 in a suitable blocking position. The blocking position of the blocking member 31 should meet the following requirements: the blocking member 31 can effectively prevent the battery cell from falling, but will not exert too much pressure on the battery cell, ensuring that the battery cell can fall to the bottom of the material box under the dual force of air blowing force and gravity. When in use, the staff can make adjustments according to the actual situation.

[0084] Reference Figure 6 The blocking member 31 includes a baffle 311 and a rotation adjustment ball 312 connected to one side of the baffle 311; a connecting member 35 is provided at the power output end of the blocking driving source 33, and the rotation adjustment ball 312 is rotatably arranged in the connecting member 35.

[0085] Specifically, the connector 35 includes at least two clamping parts 351 distributed along the circumference of the power output end of the blocking drive source 33; at least two clamping parts 351 surround a spherical groove, and the rotation adjustment ball 312 is set in the spherical groove. The rotation adjustment ball 312 can rotate in the spherical groove within a certain range to make the baffle 311 better fit the battery cell. In this embodiment, the number of the clamping parts 351 is three, and they are evenly distributed along the circumference of the power output end of the blocking drive source 33.

[0086] Furthermore, the flexible clamping mechanism 3 also includes two arc-shaped fixing bars 36, which are symmetrically arranged and surround a through hole. The arc-shaped fixing bars 36 are arc-shaped as a whole, and are provided with connecting blocks at both ends. The connecting blocks of the two arc-shaped fixing bars 36 are fixedly connected by bolts and other fasteners. The connecting member 35 is clamped in the through hole, that is, the power output end of the blocking drive source 33, the connecting member 35 and the two arc-shaped fixing bars 36 are sequentially assembled; a card slot for inserting the two arc-shaped fixing bars 36 is provided on the circumferential surface of the connecting member 35, and the axial displacement of the connecting member 35 and the two arc-shaped fixing bars 36 can be limited by the card slot; after the two arc-shaped fixing bars 36 are fixedly connected, the multiple clamping parts 351 are fixed to the power output end of the blocking drive source 33 under the limit of the two arc-shaped fixing bars 36.

[0087] Reference Figure 7 and Figure 8 A limiting protrusion 3511 is provided on the inner surface of each clamping portion 351, and a limiting groove 331 is provided on the circumferential surface of the piston rod of the blocking driving source 33 corresponding to each clamping portion 351. The limiting protrusion 3511 is inserted into the corresponding limiting groove 331. Through the plug-in cooperation between the limiting protrusion 3511 and the limiting groove 331, the axial displacement of the clamping portion 351 and the piston rod of the blocking driving source 33 is limited.

[0088] Analyzing the above structure, the axial displacement of the connecting piece 35 and the piston rod of the blocking drive source 33 can be limited by the plug-in connection method, and the radial displacement of the multiple clamping parts 351 can be limited by the two arc-shaped fixing strips 36, thereby realizing the fixed installation of the connecting piece 35 and the piston rod of the blocking drive source 33.

[0089] Furthermore, a buffer elastic pad is provided on the plane of the baffle 311 close to the flip platform 1 to further prevent the baffle 311 from damaging the battery cell.

[0090] Embodiment 2

[0091] This embodiment provides a battery cell sorting device, which differs from the device disclosed in the first embodiment in that the structure of the flexible clamping mechanism 3 is different, and the rotation adjustment ball 312, the limiting groove 331, the connecting piece 35 and the arc-shaped fixing strip 36 are not provided in this embodiment.

[0092] Reference Fig. 9 and Fig.10 In this embodiment, there are multiple blocking members 31, and the multiple blocking members 31 are distributed along the vertical direction; accordingly, there are multiple blocking drive sources 33, and the multiple blocking drive sources 33 are distributed in sequence along the vertical direction and are all installed on the slide seat 39.

[0093] Continue to refer to Fig.10 In the process of the flip platform 1 rotating from the first state to the second state, when the flip platform 1 rotates to a certain angle, the blocking member 31 located at the top is extended first, and as the flip platform 1 continues to rotate, multiple blocking members 31 are extended from top to bottom in sequence; Fig.11 When the flip platform 1 rotates to the second state, the plurality of blocking members 31 are all extended. Similarly, when the flip platform 1 rotates from the second state to the first state, the plurality of blocking members 31 are sequentially retracted from bottom to top.

[0094] The other structures of this embodiment are the same as those of the first embodiment and will not be described again.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
