After the battery is shipped, a certain amount of factory shipment is stored in the battery, and the charging and discharging parameters of the battery are often different, so the battery needs to be classified by a sorting device.

[0003] However, the capacity of the feeding box of the existing sorting device is small, which leads to a short interval time of manual feeding, so that the operator needs to frequently pay attention to the operation of the equipment, thereby increasing the labor cost and operation strength. SUMMARY

[0004] In order to reduce the frequency of feeding, the application provides a battery sorting device.

[0005] The application provides a battery sorting device, which adopts the following technical scheme:

[0006] A battery sorting device comprises a feeding mechanism, a conveying mechanism, a detection mechanism and a discharging mechanism. The feeding mechanism moves the battery to the conveying mechanism. The conveying mechanism sequentially drives the battery to the detection mechanism and the discharging mechanism. The detection mechanism is used for detecting the battery. The discharging mechanism is used for classifying and discharging the battery.

[0007] The feeding mechanism comprises a feeding box, a rotating wheel, a driving assembly and a sensing piece. Two feeding boxes are symmetrically arranged. The rotating wheel is rotationally connected to the feeding box and corresponds to the feeding box one by one. The bottom of the feeding box has a discharge port. The rotating wheel is located at the discharge port, and the outer periphery of the rotating wheel is spaced apart along the axis of the rotating wheel to form a loading groove for the battery. When the rotating wheel rotates to the position where the loading groove is opposite to the discharge port, the battery falls from the discharge port to the conveying mechanism.

[0008] The driving assembly is installed on the feeding box and is used for driving one of the rotating wheels to rotate. The sensing piece is arranged on the conveying mechanism and is used for sensing the battery passing through the conveying mechanism. When the sensing piece does not sense the battery passing through the conveying mechanism within a set time, the driving assembly is controlled to switch to driving the other rotating wheel to rotate.

Two groups of feeding boxes can increase the capacity of the feeding, and the sensing piece can monitor the supply of the battery.

DETAILED DESCRIPTION

[0039] The following will be combined with the Figures 1-7 The application will be further described in detail.

[0040] The application discloses a battery sorting device. Referring to Figure 1 , the battery sorting device comprises a support 21, a feeding mechanism, a conveying mechanism, a detection mechanism and a discharging mechanism. After the feeding mechanism feeds the batteries to the conveying mechanism, the conveying mechanism sequentially passes through the detection mechanism and the discharging mechanism to sequentially realize detection and classification and discharging of the batteries.

[0041] Referring to Figure 1 and Figure 2 , the feeding mechanism comprises a loading box 1, a rotating wheel 2, a driving assembly 3 and a sensing part 4. The loading box 1 is fixed to the support 21 and is provided with two loading boxes 1, each of which has a loading cavity 22 for placing stacked batteries, and one side of the loading box 1 is hingedly connected with an opening and closing door 12 which is magnetically attracted to the loading box 1. When the opening and closing door 12 is opened, the loading cavity 22 is opened to allow an operator to feed the batteries. When the opening and closing door 12 is closed, it abuts against the batteries to limit the movement of the batteries out of the loading box 1. The bottom of the loading box 1 is in the shape of a bucket with a gradually shortened width downward and has a discharge port 5 to guide the batteries in the loading cavity 22 to the discharge port 5. It should be noted that the two loading boxes 1 are mirror-symmetrically arranged, the opening and closing doors 12 of the two loading boxes 1 are away from each other, and a mounting gap 7 for mounting the driving assembly 3 is left between the two loading boxes 1.

[0042] Referring to Figure 1 and Figure 3 , the rotating wheel 2 corresponds to the loading box 1 one by one and rotates on the corresponding loading box 1 through a connecting shaft 23. Specifically, the rotating wheel 2 is coaxially fixed with the connecting shaft 23, the connecting shaft 23 is rotatably connected to the loading box 1 through a bearing, and the rotating wheel 2 is located in the loading box 1 and separates the discharge port 5 from the loading cavity 22, and the connecting shaft 23 penetrates through the loading box 1 into the mounting gap 7. The rotation axis of the connecting shaft 23 is parallel to the distribution direction of the two loading boxes 1, and a plurality of loading grooves 6 are uniformly and spaced apart in the circumferential direction of the outer periphery of the rotating wheel 2, and the loading grooves 6 are used for accommodating a single battery. The stacked batteries in the loading box 1 are moved to the rotating wheel 2 under the action of their own gravity to be sequentially clamped into the loading grooves 6 when the rotating wheel 2 rotates. When the rotating wheel 2 rotates to the position where the loading groove 6 is opposite to the discharge port 5, the battery in the loading groove 6 can fall to the conveying mechanism through the discharge port 5.

[0043] Referring to Figure 2 , the driving assembly 3 is mounted between the two loading boxes 1 and is used for rotating the connecting shaft 23 on one of the loading boxes 1. The sensing part 4 is an infrared sensor mounted on the conveying mechanism and is used for sensing the batteries passing through the conveying mechanism and transmitting signals to a controller (not shown in the figure). When the controller does not receive the signal of the battery passing through the conveying mechanism within a period of time, the driving assembly 3 is controlled to switch the connecting shaft 23 controlled by it to realize the switching of the feeding of the two loading boxes 1.

[0044] Referring to Figure 2And Figure 4 Specifically, the driving assembly 3 comprises a power member 31, a driving shaft 32, a ratchet wheel 33, a first pawl 34, a second pawl 35, and a linkage member 36. The driving shaft 32 is located in the installation gap 7 and rotationally connected between the two charging boxes 1, and the axis of the driving shaft 32 is parallel to the rotation axis and the distribution direction of the two charging boxes 1. The power member 31 comprises a rotation source 311 and a sprocket and chain transmission set 312. The rotation source is a rotation motor capable of forward and reverse rotation. The output end of the rotation source and the driving shaft 32 are synchronously rotated through the sprocket and chain transmission set 312, that is, the rotation source can drive the driving shaft 32 to rotate forward and reverse. The inductive member 4 cooperates with the rotation source through the controller. When the controller does not receive the signal of the inductive member 4 in a period of time, the controller controls the rotation source to switch the rotation direction.

[0045] The linkage member 36 corresponds to the charging box 1 one by one and is located in the installation gap 7. Each set of linkage member 36 comprises a driving sprocket 361, a driven sprocket 362, and a synchronous chain 363. The driving sprocket 361 and the driven sprocket 362 are sprockets, and the synchronous chain 363 is a chain. The driving sprocket 361 is coaxially rotationally sleeved on the outer wall of the driving shaft 32. The driven sprocket 362 is coaxially sleeved and fixed on the connecting shaft 23 of the corresponding charging box 1. The synchronous chain 363 is simultaneously sleeved and engaged with the driving sprocket 361 and the driven sprocket 362, so that the rotation of the driving sprocket 361 drives the connecting shaft 23 and the rotating wheel 2 to rotate.

[0046] Referring to Figure 4 And Figure 5 The ratchet wheel 33 corresponds to the driving sprocket 361 one by one. The ratchet wheel 33 is coaxially fixed with the corresponding driving sprocket 361, and the ratchet wheel 33 is coaxially surrounded by the driving shaft 32. It should be noted that the outer periphery of the ratchet wheel 33 is uniformly spaced to form outer ratchet teeth 9. The inner shaft of the ratchet wheel 33 is uniformly spaced to form inner ratchet teeth 8. The two driving sprockets 361 correspond to the inner ratchet teeth 8 of the ratchet wheel 33 in reverse inclined direction, and the outer ratchet teeth 9 are also in reverse inclined direction.

[0047] Referring to Figure 5 And Figure 6 The first pawl 34 corresponds to the ratchet wheel 33 one by one. The first pawl 34 is hinged on the driving shaft 32 and supported by the first spring. The hinge axis of the first pawl 34 is parallel to the axis of the driving shaft 32, and the first pawl 34 is driven by the elastic force of the first spring to abut on the inner ratchet teeth 8.

[0048] The second pawl 35 corresponds to the ratchet wheel 33 one by one. The outer wall of the charging box 1 is fixed with an extension seat 24. The second pawl 35 is hinged on the extension seat 24 and supported by the second spring. The hinge axis of the second pawl 35 is parallel to the axis of the driving shaft 32, and the first pawl 34 is driven by the elastic force of the second spring to abut on the outer ratchet teeth 9.

[0049] When the drive shaft 32 rotates in the forward direction, it drives one of the first pawls 34 to move towards the end face of the ratchet tooth 8 inside the corresponding ratchet 33. The outer ratchet tooth 9 of the ratchet 33 pushes the second pawl 35 to move through the arc surface, causing the ratchet 33 corresponding to one of the first pawls 34 to rotate synchronously with the drive shaft 32, thereby causing the wheel 2 corresponding to the ratchet 33 to rotate synchronously. At the same time, the other first pawl 34 moves towards the arc surface of the ratchet tooth 8 inside the corresponding ratchet 33, and the outer ratchet tooth 9 of the ratchet 33 tends to press its end face against the second pawl 35, thereby positioning the ratchet 33 corresponding to the other first pawl 34 relative to the loading box 1, thereby positioning the wheel 2 corresponding to the ratchet 33. Similarly, when the drive shaft 32 rotates in the reverse direction, the ratchet 33 that originally rotated together is positioned relative to the loading box 1, while the ratchet 33 that was originally positioned relative to the loading box 1 rotates together with the drive shaft 32.

[0050] Reference Figure 2 and Figure 4 Furthermore, the synchronous chain 363 is connected at intervals with striking elements 10 facing the outer wall of the corresponding loading box 1. The striking element 10 is an elastic telescopic rod driven by a spring, which tends to abut against the outer wall of the loading box 1. The outer wall of the loading box 1 is fixed with a mating strip 11 for the striking element 10 to abut against. The mating strip 11 extends vertically and has a wavy surface facing the striking element 10. The wavy surface undulates vertically and extends between the rotating wheel and the driven wheel 362. When the synchronous chain 363 is conveying, the striking element 10 can move on the wavy surface, thereby striking the mating strip 11 at intervals. The mating strip 11 transmits the vibration to the loading box 1, causing the loading box 1 to vibrate, thereby assisting the movement of the battery in the loading box 1. When the striking element 10 strikes the corresponding loading box 1 to assist in feeding, since the other loading box 1 is not struck by the striking element 10, the operator can stably feed the other loading box 1, so as to carry out feeding without stopping the machine.

[0051] Reference Figure 1 and Figure 7For the conveying mechanism, the conveying mechanism comprises a first conveying member 13, a second conveying member 14 and a first pushing member 15. The first conveying member 13 is a conveying belt circulated by a rotating motor, the conveying direction of the first conveying member 13 is parallel to the distribution direction of the two charging boxes 1, and the upper surface of the conveying belt of the first conveying member 13 is opposite to the discharge port 5 of the two charging boxes 1. The second conveying member 14 is a conveying belt circulated by a stepping motor, the conveying direction of the second conveying member 14 is parallel to the conveying direction of the first conveying member 13, and the discharge end of the first conveying member 13 is opposite to the feeding end of the second conveying member 14. The detection mechanism is arranged between the discharge end of the first conveying member 13 and the feeding end of the second conveying member 14. The first pushing member 15 is a cylinder installed on the frame of the first conveying member 13, the first pushing member 15 pushes the battery at the discharge end of the first conveying member 13 into the detection mechanism, and the battery pushed by the first pushing member 15 pushes the battery originally located at the detection mechanism into the feeding end of the second conveying member 14, and the second conveying member 14 drives the battery to stepwise move into the discharging mechanism.

[0052] For the detection mechanism, the detection mechanism comprises a base 16, a movable detection head 17 and a code scanner 18. The base 16 is fixedly connected between the frame of the first conveying member 13 and the frame of the second conveying member 14, the base 16 is formed with an arc groove for limiting the battery, the movable detection head 17 has two and moves on the opposite ends of the base 16 in the direction of approaching or moving away from each other, when the battery is located on the base 16, the movable detection head 17 clamps the two levels of the battery in the direction of approaching each other to detect the voltage, resistance and other conditions of the battery. The code scanner 18 is connected to the output end of the first pushing member 15, the first pushing member 15 contacts the battery through the code scanner 18, so that the code scanner 18 reads the information of the battery when pushing the battery, and the detection information of the movable detection head 17 and the reading information of the code scanner 18 are combined and transmitted to the controller.

[0053] For the discharging mechanism, the discharging mechanism comprises a second pushing member 19 and a distribution box 20. The second pushing member 19 is a cylinder and is installed on a support 21, and a plurality of second pushing members 19 are uniformly and spacedly installed along the distribution direction of the second conveying member 14, each second pushing member 19 corresponds to a different battery type, and the distribution box 20 and the second pushing member 19 are located on opposite sides of the second conveying member 14. The second conveying member 14 conveys the battery, and when the battery is opposite to the corresponding second pushing member 19, the controller controls the second pushing member 19 to push the battery into the distribution box 20 to complete the sorting of the battery.

[0054] The implementation principle of the battery sorting device in the embodiment of the application is that the operator can load two loading boxes 1 each time, when the forward rotation of the rotation source 311 drives one of the rotating wheels 2 to rotate to load, the other rotating wheel 2 is positioned relative to the loading box 1. When the loading of one of the loading boxes 1 is completed, the inductor 4 monitors that the first conveying part 13 does not convey the battery in a period of time, and drives the rotation source 311 to rotate reversely to drive the other rotating wheel 2 to rotate to load, so that the other loading box 1 loads.
