After different battery cells are placed in different receiving boxes, they will not fall directly to the bottom. The first battery cell will slide to the surface of the receiving bottom plate and press the receiving bottom plate downward under the action of its own gravity. At this time, the battery cell is in the original position of the receiving bottom plate, and so on. When the subsequent battery cells slide down into the receiving box, the height difference remains the same as that of the first battery cell, avoiding the damage of the battery cells caused by a large impact when falling due to a large height difference.

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] like Figure 1 - Fig.16 As shown, the present invention provides:

[0064] The defective battery cell sorting device includes a frame 10 and a mounting frame 20. The frame 10 is equipped with a conveyor 30. A sorting mechanism 80 is installed in the frame 10. The mounting frame 20 is equipped with a horizontal lifting mechanism 40. The top and bottom of the mounting frame 20 are fixed with mounting covers 50. The two mounting covers 50 are jointly equipped with a detection mechanism 60.

[0065] like Figure 1 , Figure 2 and Fig.12 , guide assemblies 70 are installed on both sides of the conveyor 30;

[0066] The guide assembly 70 includes an extension plate 71 fixed to the conveyor 30, the extension plate 71 is slidably mounted with a side plate 72, the lower surface of the side plate 72 is threaded with a knob bolt for fixing the position, and the extension plate 71 is embedded with a plurality of first balls 73;

[0067] Specifically, after loosening the knob bolt, the side plate 72 can be slid on the extension plate 71. After sliding to a position suitable for the size of the battery cell, the knob bolt can be tightened to fix the position of the side plate 72. When the battery cell moves on the conveyor 30, the two ends of the battery cell are located on the extension plate 71. At this time, the first ball 73 can help the battery cell to slide.

[0068] like Figure 1 , Figure 5 and Figure 8 The horizontal lifting mechanism 40 includes a shaft column 41 rotatably connected to the mounting frame 20 and a motor 44 fixed to the outer wall of the mounting frame 20. The output end of the motor 44 is spline-connected to one end of the shaft column 41. A circular frame 42 is fixed to the shaft column 41. A plurality of clamping units 43 for fixing battery cells are rotatably connected to the inner wall of the circular frame 42.

[0069] The circular ring frame 42 includes a connecting frame 421 fixedly sleeved on the shaft column 41 , and a ring body 422 is fixed on the connecting frame 421 . Preferably, the connecting frame 421 is in a cross shape.

[0070] The clamping unit 43 includes two receiving frames 436 for receiving battery cells. Connecting columns 433 are fixed on the outer walls of the two receiving frames 436. A plurality of gravity rods 431 are rotatably connected to the connecting frame 421. A retaining sleeve 432 is fixed to one end of the gravity rod 431. The connecting columns 433 are inserted into the retaining sleeve 432. The gravity rods 431 are grouped in pairs. Under the action of the gravity of the gravity rods 431, the receiving frames 436 can always remain in a horizontal state when the circular frame 42 rotates.

[0071] The connecting column 433 is provided with a plurality of sinking holes distributed in a circumferential array, and a first spring 434 is fixed in the sinking hole. A limiting column 435 is fixed at one end of the first spring 434. A plurality of limiting holes matching the limiting column 435 are provided on the retaining sleeve 432. The first spring 434 drives the limiting column 435 to engage in the limiting hole, so that the position of the connecting column 433 is fixed after being inserted into the retaining sleeve 432. After the limiting column 435 is pressed inwardly, the limiting column 435 is separated from the limiting hole. At this time, the limiting column 435 can be pulled outward, and then the receiving frame 436 can be disassembled;

[0072] A contact plate 437 is slidably installed in the receiving frame 436 through a slide groove, and a second spring 438 is installed on one side of the contact plate 437. One end of the second spring 438 is fixed to the inner wall of the receiving frame 436. Preferably, the receiving frame 436 is made of transparent material so that the receiving frame 436 will not block the battery cell, and a silicone pad is provided on the side of the contact plate 437 that contacts the battery cell.

[0073] An extension column is fixed to one end of both sides of the frame 10 close to the receiving frame 436, and an upper release wedge 439 is fixed to one end of the extension column for resisting the contact plate 437 to move inward;

[0074] Specifically, the circular frame 42 rotates clockwise, and when the receiving frame 436 rotates to the point where its inner bottom wall is in the same horizontal plane as the surface of the conveyor 30, during the rotation to this state, the upper release wedge 439 pushes the resistance plate 437 to gradually move toward the inside of the receiving frame 436. At this time, the battery cell can smoothly enter the receiving frame 436 under the action of the conveyor 30. After continuing to move upward, the upper release wedge 439 separates from the resistance plate 437. At this time, under the action of the second spring 438, the resistance plate 437 abuts against the end of the battery cell, thereby clamping and fixing the battery cell to prevent it from shifting during movement.

[0075] like Figure 2 , Figure 8 and Fig.10 The detection mechanism 60 includes two moving components 61 assembled in the mounting cover 50, and the two moving components 61 are slidably equipped with an image capturing device 62 for photographing the battery sheet;

[0076] The moving assembly 61 includes a guide rod 611, and the image capturing device 62 is slidably mounted on the guide rod 611. A third spring 612 is sleeved on the guide rod 611. Shock-absorbing pads are fixed at both ends of the third spring 612. The two shock-absorbing pads are respectively fixed to the inner wall of the mounting cover 50 and the outer wall of the image capturing device 62.

[0077] A transmission column is rotatably connected to the outer wall of the mounting cover 50. A cam 613 for pushing the image pickup device 62 to move along the guide rod 611 is fixed to one end of the transmission column inserted into the mounting cover 50. A single-groove pulley 614 is fixed to the other end of the transmission column. A double-groove pulley 615 adapted to the single-groove pulley 614 is fixed to the other end of the shaft column 41. The double-groove pulley 615 and the two single-groove pulleys 614 are respectively meshed and connected with two synchronous belts 616.

[0078] Specifically, when the motor 44 drives the shaft column 41 to rotate, the shaft column 41 simultaneously drives the double-groove pulley 615 to rotate, and under the action of the two synchronous belts 616, the two single-groove pulleys 614 rotate, thereby causing the upper and lower cams 613 to rotate, so that the image capture device 62 located above moves from left to right and gradually moves to the middle position, and the image capture device 62 located below moves from right to left and gradually moves to the middle position. During the movement, the image capture device 62 located above shoots the battery cells that are gradually lifted upward from a state flush with the conveyor 30, and the image capture device 62 located below shoots the battery cells that gradually move from the highest point to the lowest point.

[0079] The image acquisition device 62 includes a housing 621 and a camera 622 installed on the housing 621. A switch slot is provided on the side of the housing 621 away from the camera 622. A fixed contact metal sheet 623 is fixed in the middle of the inner wall of the switch slot. Return springs 624 are fixed on both sides of the inner wall of the switch slot. A pressing cap 625 is fixed at one end of the two return springs 624. A movable contact metal sheet 626 is fixed in the middle of the inner side of the pressing cap 625. A plurality of touch units 63 for resisting the pressing cap 625 to move into the switch slot are mounted on the ring body 422. When the pressing cap 625 moves inward until the movable contact metal sheet 626 contacts the fixed contact metal sheet 623, the camera 622 starts to take pictures and is turned off after separation.

[0080] The touch unit 63 includes a vertical rod 631 fixed to the ring body 422, a push rod 632 is slidably sleeved on the vertical rod 631, a buffer pad is fixed on the top of the vertical rod 631 and the inner top wall of the push rod 632, and a fourth spring 633 is fixedly assembled on the two buffer pads. Both sides of the push rod 632 and the end of the pressing cap 625 are arc-shaped. Under the action of the fourth spring 633, when the ring body 422 rotates and the camera 622 moves, the push rods 632 at different positions can always push against the pressing cap 625, so that during the rotation process, the pressing cap 625 is pushed inward by the push rod 632, thereby starting the camera 622 to take pictures, and there is no need to set up an additional sensor to transmit the battery cell position to the camera 622 and then take pictures through the control system;

[0081] like Figure 4 , Figure 5 , Figure 6 and Fig.11 The sorting mechanism 80 includes a receiving unit 81 connected to the rack 10 , and a diversion unit 82 for guiding the battery cells into different positions in the receiving unit 81 is installed on one side of the receiving unit 81 .

[0082] The shunt unit 82 includes an electric push rod 821 fixed to the mounting frame 20, an assembly frame 822 is fixed to the top of the electric push rod 821, and an electric roller shaft and a roller are respectively installed at both ends of the assembly frame 822, and a conveyor belt 823 is jointly installed on the electric roller shaft and the roller. Connecting seats are fixed on both sides of the assembly frame 822, and one end of the two connecting seats is jointly fixedly connected to a lower slide plate 824. After the electric roller shaft is started, the conveyor belt 823 can be rotated, and then the contacted solar panel can be driven to move from right to left;

[0083] Extension rods are fixed to the ends of the tops on both sides of the assembly frame 822 away from the connecting seat, and lower release wedges 825 are fixed to one end of the extension rods and the tops on both sides of the assembly frame 822 for resisting the inward sliding of the contact plate 437. When the battery cell photographed and identified is moved to a predetermined position according to whether it is defective, the assembly frame 822 is moved upward by the electric push rod 821, so that the upper surface of the conveyor belt 823 contacts the lower surface of the battery cell. During the upward movement, the lower release wedge 825 gradually pushes the contact plate 437 to move into the receiving frame 436, contacting the restriction on the battery cell. At this time, the battery cell can be moved outward from the receiving frame 436 through the conveyor belt 823 and moved into the receiving box through the lower slide plate 824.

[0084] The receiving unit 81 includes a bottom box 811 fixed to the frame 10, and two storage chambers are provided in the bottom box 811 to respectively insert a good product receiving box 812 and a bad product receiving box 813, and an inclined chamber is provided on the upper surface of the bottom box 811, and a good product drop groove 814 is provided on one side of the bottom wall of the inclined chamber, and a bad product drop groove 815 is provided on one side of the bottom box 811, and a plurality of second balls are embedded on the other side of the bottom wall of the inclined chamber and the upper surface of the lower slide plate 824, and the second balls play a role of helping the battery sheet to slide down;

[0085] The inner bottom walls of the good product receiving box 812 and the defective product receiving box 813 are fixed with multiple fifth springs 816, and the top ends of the multiple fifth springs 816 are commonly fixed with a receiving bottom plate 817. The two receiving bottom plates 817 are respectively slidably connected in the good product receiving box 812 and the defective product receiving box 813. When the battery cells fall on the receiving bottom plate 817, the receiving bottom plate 817 will be pressed down by the action of their gravity. In the initial state, the receiving bottom plate 817 is lower than the edge of the receiving box. In this state, the battery cells will not produce impact after sliding down to its surface.

[0086] Specifically, when the defective battery cell sorting device is working / in use:

[0087] First, the battery cells to be inspected and sorted are placed on the surface of the conveyor 30 and moved toward the horizontal lifting mechanism 40. At this time, the horizontal lifting mechanism 40 is in the following position: Figure 1 In the initial state shown, the inner bottom wall of the receiving frame 436 and the surface of the conveyor 30 are at the same level, and the upper release wedge 439 pushes the contact plate 437 to move toward the inside of the receiving frame 436. At this time, the battery cell at the front is moved into the receiving frame 436 under the action of the conveyor 30;

[0088] Then, the motor 44 is started to rotate the shaft column 41 with the circular frame 42. During the process, the receiving frame 436 moves upward with the battery cell in a horizontal state. At the same time, the upper release wedge 439 is separated from the contact plate 437 in the receiving frame 436. Under the action of the second spring 438, the contact plate 437 contacts the end of the battery cell, thereby clamping and fixing the battery cell.

[0089] In the process of moving from the initial state to the highest point, the shaft column 41 simultaneously drives the double-groove pulley 615 to rotate, and under the action of the two synchronous belts 616, the two single-groove pulleys 614 rotate, thereby causing the upper and lower cams 613 to rotate, so that the image capture device 62 located at the top gradually moves from left to right to the middle position and reciprocates, and the multiple touch units 63 on the circular frame 42 intermittently abut against the pressing cap 625 to start the upper camera 622, and in the process of lifting the battery cell horizontally upward, the upper surface of the battery cell is intermittently and repeatedly photographed. When the battery cell moves from the highest point to the lowest point, the lower cam 613 drives the image capture device 62 located at the bottom to move from right to left to the middle position and reciprocate, and at the same time, the touch units 63 intermittently abut against the pressing cap 625 to start the lower camera 622, and in the process of moving the battery cell horizontally downward, the lower surface of the battery cell is intermittently and repeatedly photographed, and the photographed photos are recognized by the image processing system;

[0090] When the battery cell is identified as defective, Figure 4 After reaching the position shown, the conveyor belt 823 stops, and then the electric push rod 821 is started to move the conveyor belt 823 and the lower slide plate 824 upward, so that the lower slide plate 824 corresponds to the defective product drop slot 815. During the upward movement, the lower release wedge block 825 gradually pushes against the contact plate 437 and slides inward to release the restriction on the battery cell. Then the electric roller shaft is started to rotate the conveyor belt 823 to move the battery cell out of the receiving frame 436. After being moved out, the battery cell slides through the lower slide plate 824 to the defective product receiving box 813 for collection.
