[0029] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] Reference Figure 1 , Figure 1: is a structural schematic diagram of a defective product sorting device in an embodiment, and the defective product sorting device in this embodiment includes a material conveying mechanism 1, a sorting mechanism 2 and a control mechanism 3. The material conveying mechanism 1 includes a material conveying component 11 and a positioning component 12, and the positioning component 12 is arranged at the material discharging end of the material conveying component 11. The sorting mechanism 2 includes a sorting component 21 and a collecting component 22, and the collecting component 22 has a plurality of collecting positions, and the sorting end of the sorting component 21 moves between the material discharging end of the material conveying component 11 and the plurality of collecting positions. The control mechanism 3 includes a control component 31 and a scanning component 32, and the scanning end of the scanning component 32 faces the material conveying component 11, and the control component 31 is electrically connected to the sorting component 21 and the scanning component 32 respectively. The material conveying component 11 conveys defective products to the material discharging end, the positioning component 12 performs positioning and calibration on the position of the defective products, the scanning component 32 scans the defective products and transmits the information to the control component 31, and the control component 31 controls the sorting component 21 to sort the defective products to the corresponding collecting positions for collection.

[0032] The defective product sorting equipment in this embodiment is placed on the floor of the factory for use, and the defective battery cells generated in the process of lithium battery production are classified and sorted. The material transfer component 11 transfers the defective battery cells one by one to the sorting component 21 for sorting, and the position of the defective product on the material transfer component 11 is positioned and adjusted by the positioning component 12. The scanning component 32 scans the information on the defective product and transmits the information to the control component 31. The control component 31 controls the sorting component 21 to sort the defective product to the corresponding collection position for collection. Through the setting of the control component 31 and the scanning component 32, this embodiment can accurately identify defective products, ensure that defective products can be accurately sorted, improve the accuracy of sorting, and avoid errors, omissions, and mixing of defective products due to sorting errors. At the same time, since the control component 32 is electrically connected to the sorting component 21 and the scanning component 32 respectively, the control component 31 can control the sorting component 21 to sort the defective products to the corresponding collection position according to the information scanned by the scanning component 32, so as to realize automatic sorting of defective products, reduce labor costs, and improve sorting efficiency.

[0033] Refer to Figure 2 , Figure 2 for Figure 1The enlarged schematic diagram of the middle A part shows that, preferably, the positioning assembly 12 includes a stopper 121 and a position calibration member 122. The stopper 121 is arranged at the discharge end of the material transfer assembly 11, and the calibration end of the position calibration member 122 is opposite to the defective product at the discharge end. In specific applications, the material transfer assembly 11 in this embodiment includes two material transfer racks, a material transfer belt, two transmission shafts and a material belt drive motor. The two material transfer racks are arranged at intervals, and the two ends of one transmission shaft are respectively rotatably connected to one end of the two material transfer racks, and the two ends of the other transmission shaft are respectively rotatably connected to the other ends of the two material transfer racks. The material transfer belt is sequentially wound around the two transmission shafts, and the driving end of the material belt drive motor is connected to one of the transmission shafts. In this way, the defective products can be sequentially transferred to the discharge end of the material transfer assembly 11. In this embodiment, the discharge end of the material transfer assembly 11 is also the end of the material transfer belt close to the sorting assembly 21. The other end of the material transfer belt can be arranged on one side of the defective product feeding mechanism, and the defective product feeding mechanism feeds the defective battery cells one by one to the material transfer belt. By setting the position limiter 121, when the defective product on the conveyor belt is transmitted to the discharge end, the position limiter 121 blocks the defective product so that it cannot move further, thereby realizing the preliminary positioning of the defective product. By setting the position calibration member 122, when the defective product is initially positioned, the position calibration member 122 pushes the defective product to make it stick to one of the conveyor racks. At this time, the defective product is located within the scanning range of the scanning component 32, ensuring that the scanning component 32 can accurately scan the information code on the defective product. It can be understood that the position limiter 121 performs preliminary positioning of the position of the defective product, that is, the longitudinal position of the defective product is positioned, and the position calibration member 122 performs precise positioning of the position of the defective product, that is, the lateral position of the defective product is positioned. In this way, it can be ensured that the relative position of the defective product is fixed when it moves to the discharge end, that is, it is directly opposite to the scanning end of the scanning component 32, ensuring that the scanning component 32 can accurately scan the information code on the defective product, avoiding the occurrence of missed scanning, scanning failure, etc., which causes the equipment to report an error, and improves the stability and automation of the equipment operation. Specifically, the limiting member 121 is a limiting stop bar, and the position calibration member 122 includes a calibration cylinder and a push block. The calibration cylinder is connected to the push block. The calibration cylinder is arranged on one of the material transfer racks, and the push block is used to push defective products to fit with the other material transfer rack.

[0034] Refer to Figure 3 , Figure 3 for Figure 1In the enlarged schematic diagram of the middle B part, preferably, the sorting assembly 21 includes a sorting track member 211 and a sorting member 212. The sorting track member 211 is arranged along the direction in which the multiple collecting positions are connected in sequence, and the sorting member 212 is movably arranged on the sorting track member 211. In specific applications, the sorting track member 211 includes a track frame, a track screw and a track motor. The track frame is arranged along the direction in which the multiple collecting positions are connected in sequence and is located on one side of the multiple collecting positions. The track screw is rotatably arranged in the track frame, the driving end of the track motor is connected to the track screw, and the sorting member 212 is arranged on the track screw. It can be understood that the sorting component 212 and the track motor are electrically connected to the control component 31 respectively, and the scanning component 32 scans the information code on the defective product at the discharge end and transmits its information to the control component 31. After the control component 31 processes the information, it controls the sorting component 212 to take the defective product from the discharge end, and then controls the rotation of the track motor. The rotation of the track motor drives the track screw to rotate, and the rotation of the track screw drives the sorting component 212 to move linearly with the track screw, thereby driving the sorting component 212 to move to the corresponding collection position, and sorting the defective products to the corresponding collection position for collection. Specifically, the control component 31 is an industrial computer, which is equipped with an MES intelligent management system. The control component 31 also includes a working condition display screen and multiple control buttons. Workers can intuitively observe the working status of the equipment through the working condition display screen. The multiple control buttons are reset, start, stop, manual / automatic switching, emergency stop and other function buttons, which are used to control the equipment to switch to the corresponding working state. The scanning component 32 is a barcode scanning gun, which is arranged on one of the material transmission racks. The defective products have information codes, that is, all relevant information of the defective products in the front-end production process is recorded in the information code. After the scanning component 32 scans the information code, it transmits the information to the control component 31. The control component 31 analyzes the information to distinguish the defective type of the defective products, thereby deciding at which collection position the defective products should be sorted.

[0035] Re-reference Figure 3Preferably, the sorting part 212 includes a moving part 2121, a lifting part 2122 and a sorting part 2123, the moving part 2121 is movably arranged on the sorting track part 211, the lifting part 2122 is movably arranged on the moving part 2121, and the sorting part 2123 is arranged on the lifting part 2122. In specific applications, the moving part 2121 includes a moving frame and a moving nut. The moving nut is arranged on the track screw rod, and the moving frame is sleeved outside the moving nut. The lifting part 2122 is a lifting cylinder, which is fixed to the moving frame, and the driving end of the lifting cylinder is connected to the sorting part 2123. The sorting part 2123 is a vacuum suction cup. It can be understood that the track motor drives the track screw rod to rotate, and the rotation of the track screw rod causes the moving nut to move linearly on the track screw rod. When it moves to above the discharge end, the lifting cylinder drives the sorting part 2123 to descend and absorb defective products and then rise. Then the track motor drives the track screw rod to rotate, and the rotation of the track screw rod causes the moving nut to move linearly on the track screw rod. When it moves to above the corresponding collection position, the lifting cylinder drives the sorting part 2123 to descend and put the defective products into the corresponding collection position for collection, thereby realizing automatic sorting of defective products. Furthermore, the sorting part 212 also includes a rotating part 2124, which is rotatably arranged on the lifting part 2122, and the sorting part 2123 is arranged on the rotating part 2124. Since the multiple collection positions are located on the same straight line, and the discharge end and the multiple collection positions are not located on the same straight line, through the setting of the rotating part 2124, after the sorting part 2123 absorbs defective products, the rotating part 2124 drives the sorting part 2123 to rotate with the mobile frame as the rotating axis, so that the sorting part 2123 is located on the same straight line with the multiple collection positions from a top view. In this way, only one section of the sorting track part 211 can be set, which simplifies the internal structure of the equipment and reduces the difficulty of daily maintenance. Specifically, the rotating part 2124 includes a rotating cylinder and a rotating block, the rotating cylinder is connected to the driving end of the lifting cylinder, the driving end of the rotating cylinder is connected to one end of the rotating block, and the vacuum suction cup is arranged at the other end of the rotating block.

[0036] Refer to Figure 4 , Figure 4 for Figure 1The enlarged schematic diagram of the middle C part shows that, preferably, the collection component 22 includes a quantity sensing member 221 and a plurality of classification boxes 222, and the plurality of classification boxes 222 are respectively arranged at a plurality of collection positions, and the quantity sensing member 221 is electrically connected to the control component 31, and the sensing end of the quantity sensing member 221 faces the plurality of classification boxes 222. It can be understood that each classification box 222 collects the same type of defective batteries, and through the setting of the quantity sensing member 221, the number of defective batteries in the classification box 222 can be sensed. When the number of defective batteries in the classification box 222 reaches a preset number, the quantity sensing member 221 will send a signal to the control component 31, and the control component 31 will issue an alarm to remind the operator to take out the defective batteries in the classification box 222 in time to improve production efficiency. Furthermore, the quantity sensing member 221 is a beam sensor, and the tops of the plurality of classification boxes 222 are provided with beam notches 2221, and the plurality of beam notches 2221 are connected in sequence to form a straight line, and the sensing ends of the quantity sensing member 221 are arranged at both ends of the straight line. Through the setting of the through-beam sensor, when the operator's hand reaches into the classification box 222 to take out the defective battery cells, the operator's hand will block the infrared rays emitted by the through-beam sensor. At this time, the control component 31 receives the signal and controls the sorting component 21 not to sort the defective products into the classification box 222, thereby avoiding the sorting component 21 from causing harm to the operator and improving safety.

[0037] Refer to Figure 5-6 , Figure 5 is a schematic structural diagram of a defective product sorting device with a sorting housing in an embodiment, Figure 6Another structural schematic diagram of a defective product sorting device with a sorting shell in an embodiment, preferably, the sorting mechanism 2 also includes a sorting shell 23, and a plurality of classification boxes 222 are arranged in the sorting shell 23. A plurality of material taking ports 231 are provided on a side of the sorting shell 23 away from the material transfer component 11, and the plurality of material taking ports 231 are respectively arranged corresponding to the plurality of classification boxes 222. In specific application, the operator is located on the side of the sorting shell 23 away from the material transfer component 11, that is, the side with the material taking ports 231. When one of the classification boxes 222 collects a certain number of defective products, the operator takes out defective products from the classification box 222 through the material taking ports 231. Furthermore, the collection component 22 also includes a plurality of position sensors 223, each of the classification boxes 222 is directly opposite to the sensing end of a position sensor 223, and the plurality of position sensors 223 are respectively electrically connected to the control component 31. It is understandable that the operator can also directly take out the entire classification box 222 from the material taking port 231, take out the defective products from the classification box 222, and then put the classification box 222 back to the collection position to improve the material taking efficiency. Through the setting of the position sensor 223, on the one hand, it can detect whether the position of the classification box 222 is accurately placed when the classification box 222 is put back. If it is inaccurate, the control component 31 will issue an alarm to prompt the operator to ensure that the defective products can accurately fall into the classification box 222 during the sorting process. On the other hand, when the classification box 222 is taken away for material taking, the position sensor 223 transmits the signal to the control component 31, and the control component 31 stops sorting defective products to the collection position. Specifically, the position sensor 223 is a position sensor.

[0038] Embodiment 2:

[0039] The difference between the defective product sorting device in this embodiment and the first embodiment is that the defective product sorting device in this embodiment does not have a classification box 222. Specifically, the collection component 22 in this embodiment includes a plurality of conveyor belts, one end of each of which is respectively corresponding to a plurality of collection positions, and the other ends of each of which extend in a direction away from the collection position. In specific applications, the conveyor belt in this embodiment is a conveyor belt, and this embodiment uses a plurality of conveyor belts instead of a plurality of classification boxes 222. In this way, when the sorting component 21 is sorting, different types of defective products are directly sorted onto the corresponding conveyor belts, and different types of defective products are directly transported to the corresponding next process for subsequent processing through the conveyor belts, thereby further improving the sorting efficiency and the degree of automated sorting.

[0040] In summary, the material transfer component transfers defective battery cells one by one to the sorting component for sorting, the position of the defective product on the material transfer component is positioned and adjusted by the positioning component, the scanning component scans the information on the defective product and transmits the information to the control component, and the control component controls the sorting component to sort the defective product to the corresponding collection position for collection. Through the setting of the control component and the scanning component, this embodiment can accurately identify defective products, ensure that defective products can be accurately sorted, improve the accuracy of sorting, and avoid mistakes, omissions, and mixing of defective products due to sorting errors. At the same time, since the control component is electrically connected to the sorting component and the scanning component respectively, the control component can control the sorting component to sort the defective products to the corresponding collection position according to the information scanned by the scanning component, thereby realizing automatic sorting of defective products, reducing labor costs, and improving sorting efficiency.

[0041] In addition, through the setting of the quantity sensing component, the number of defective products in the classification box can be sensed. When the number of defective products in the classification box reaches the preset number, the quantity sensing component will send a signal to the control component, and the control component will issue an alarm to remind the operator to take out the defective products in the classification box in time, thereby improving production efficiency. When the quantity sensing component senses that the operator's hand reaches into the classification box to take out the defective battery cell, it will send a signal to the control component. The control component receives the signal and controls the sorting component not to sort the defective products into the classification box, thereby avoiding the sorting component from causing harm to the operator and improving safety.
