[0003] In the existing technology, the detection system for NG batteries lacks the option of reprocessing. NG batteries are excluded after only one identification, and there is a lack of secondary detection and identification for suspected NG batteries, which leads to a high defect rate and increases the manufacturing cost of batteries. Utility Model Content

[0004] The purpose of this invention is to provide a battery NG rejection and refill hybrid system and battery production line, so as to improve the technical problem that the existing NG battery detection system has high battery manufacturing costs due to the lack of refill options.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] In a first aspect, this utility model provides a battery NG exclusion and re-addition hybrid system, comprising:

[0007] The discharge mechanism includes a production line and a battery detection device installed on the production line. The production line carries multiple batteries, and the battery detection device is used to identify and mark the multiple batteries. Specifically, batteries that are first identified as NG are marked as suspected NG batteries, and batteries that are identified as NG again are marked as confirmed NG batteries.

[0008] The NG battery reprocessing mechanism includes a reprocessing line for reprocessing suspected NG batteries, allowing them to re-enter the main production line for re-identification by the battery testing device.

[0009] In an optional implementation, the battery NG exclusion and re-addition hybrid system further includes:

[0015] In an optional embodiment, the buffer is provided with a rectangular array of multiple receiving slots, and the receiving slots located in the same row or column are used to place different types of the confirmed NG batteries.

[0016] In an optional implementation, the battery NG exclusion and re-addition hybrid system further includes:

[0017] A battery gripping and transferring mechanism includes a base, an arm connected to the base, and a gripping assembly connected to the arm. The gripping assembly is used to grip the battery under the drive of the arm and to transfer the battery between the discharge mechanism and the NG battery refilling mechanism.

[0044] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0045] The following detailed description of the overall structure, working principle, and technical effects of the battery NG exclusion and re-addition mixing system and battery production line provided by this utility model, through embodiments and in conjunction with the accompanying drawings, is a practical example.

[0046] Example 1:

[0047] This embodiment provides a battery NG removal and re-addition hybrid system for a battery production line and a battery production line having the same. The battery NG removal and re-addition hybrid system is used to detect batteries during the battery manufacturing process and remove NG batteries in a timely manner, thereby eliminating safety hazards during later use.

[0048] It should be noted that the battery NG rejection and re-addition hybrid system provided in this embodiment can be applied to the detection and NG rejection of various types of batteries, such as cylindrical batteries, prismatic batteries, and pouch batteries.

[0049] Please see Figure 1 The battery NG rejection and refill mixing system provided in this embodiment includes a discharge mechanism (not shown in the figure) and an NG battery refill mechanism 10 disposed downstream of the discharge mechanism; wherein the discharge mechanism includes a production line and a battery detection device disposed on the production line; the production line carries multiple batteries, and the battery detection device is used to identify and mark the multiple batteries.

[0050] In this embodiment, the main production line in the discharge mechanism can be the output logistics line after battery assembly and formation are completed; the battery detection device set on the discharge mechanism is used to detect indicators such as voltage, capacity, internal resistance, appearance size, and foreign matter inside the battery on the main production line. The battery detection device can be a device used in the prior art to detect the above indicators, as long as it can realize the detection and marking functions.

[0051] When a battery on the main production line passes through the battery testing device for the first time, the device will test the battery and determine whether it is an NG battery. If it is, it will be marked as a suspected NG battery and output to the NG battery reprocessing mechanism 10. If not, the battery will be output to the next production process.

[0052] The aforementioned NG battery reprocessing mechanism 10 includes a reprocessing line 11, which is used to reprocess suspected NG batteries, allowing them to re-enter the main production line for re-identification by the battery testing device.

[0053] The suspected NG batteries were temporarily stored in the NG battery reprocessing facility 10 and eventually re-entered the main production line for secondary testing.

[0054] When a suspected NG battery passes through the battery detection device, the device will perform a secondary test on the suspected NG battery and determine whether it is an NG battery. If it is, it will be marked as an confirmed NG battery and output to the NG battery output mechanism 20. If not, the battery will be output to the next production process.

[0055] Please see Figure 1 and Figure 2In this embodiment, the NG battery output mechanism 20 is used to output a confirmed NG battery, and it includes an NG output line 21.

[0056] In this embodiment, the NG output line 21 includes multiple independently operating branch lines 22. The multiple branch lines 22 are independently controlled and operated logistics lines, used to output confirmed NG batteries of different NG types, such as appearance NG, voltage NG, and battery internal foreign matter NG.

[0057] In order to improve work efficiency and space utilization, in this embodiment, the battery is gripped and transferred between the discharge mechanism and the NG battery re-feeding mechanism 10, and between the discharge mechanism and the NG battery output mechanism 20, by the battery gripping and transfer mechanism 40.

[0058] Please see Figure 3 Specifically, the battery gripping and transferring mechanism 40 includes a base 41, an arm 42 connected to the base 41, and a gripping assembly 43 connected to the arm 42.

[0059] In this embodiment, the arm 42 includes a lifting arm 421, a first rotating arm 422, and a second rotating arm 423 connected together. The lifting arm 421 is vertically mounted on the base 41. The end of the lifting arm 421 away from the base 41 is movably connected to the first rotating arm 422. The end of the first rotating arm 422 away from the lifting arm 421 is movably connected to the second rotating arm 423. The end of the second rotating arm 423 away from the first rotating arm 422 is provided with the gripping assembly 43.

[0060] In this embodiment, the gripping assembly 43 is used to grip the battery, and includes a lifting control component 431 and a gripping execution end 432. The lifting control component 431 is used to drive the gripping execution end 432 to move in the height direction. In actual operation, a lifting cylinder or an electric telescopic rod can be selected as the lifting control component 431.

[0061] Furthermore, the aforementioned gripping execution end 432 includes a connecting plate 4321 and a clamping plate 4322 disposed on the connecting plate 4321. The gripping execution end 432 can grip single or multiple batteries through the clamping plate 4322.

[0062] It is understandable that the aforementioned gripping execution end 432 also includes at least a driving component and a position recognition component, so that when there are multiple batteries to be gripped, it can grip at least the batteries in the same column / row at the same time.

[0063] In other embodiments, the battery gripping and transfer mechanism 40 may also have multiple other degrees of freedom in various directions to enable flexible transfer and gripping of the battery.

[0064] Please see Figure 4The battery NG exclusion and re-addition hybrid system provided in this embodiment works as follows:

[0065] After assembly, the batteries are output from the main production line on the discharge mechanism and tested by a battery testing device. The battery testing device checks multiple quality indicators of the batteries and determines whether they are NG batteries. If so, they are marked as suspected NG batteries and transferred to the NG battery reprocessing mechanism 10 via the battery gripper transfer mechanism 40. If not, the batteries are output to the next production process. Suspected NG batteries are temporarily stored in the NG battery reprocessing mechanism 10 and then transferred back to the main production line by the battery gripper transfer mechanism 40 for secondary testing. The battery testing device tests the suspected NG batteries again and determines whether they are NG batteries. If so, they are marked as confirmed NG batteries and transferred to the NG battery output mechanism 20 via the battery gripper transfer mechanism 40. If not, the batteries are output to the next production process.

[0066] This hybrid battery NG rejection and reprocessing system, by incorporating an NG battery reprocessing mechanism 10, allows suspected NG batteries to undergo secondary testing by the battery testing device. This improves testing accuracy while reducing the defect rate during battery production, thereby lowering battery production costs. Consequently, battery production lines employing this hybrid system also achieve the technical benefits of improving the accuracy of NG battery detection and reducing the battery production defect rate.

[0067] In addition, by setting up the battery gripping and transfer mechanism 40, the efficiency of battery transfer between various devices and mechanisms is improved, thereby increasing production efficiency. On the other hand, the battery gripping and transfer mechanism 40 is set up independently, which improves the utilization of design space, makes the layout compact, and saves space.

[0068] Example 2:

[0069] Please refer to Figure 5 and Figure 7 This embodiment also provides a battery NG rejection and refill mixing system and a battery production line. Its overall structure, working principle and technical effects are basically the same as those of Embodiment 1. The difference is that the battery NG rejection and refill mixing system provided in this embodiment also includes a buffer mechanism 30. The buffer mechanism 30 is disposed between the NG battery refilling mechanism 10 and the NG battery output mechanism 20. When the battery detection device continuously detects confirmed NG batteries, the buffer mechanism 30 is activated. The buffer mechanism 30 is used to place and buffer the confirmed NG batteries, thereby unifying the production cycle.

[0070] Please continue reading. Figure 5 and Figure 6In this embodiment, the buffer mechanism 30 includes a fixing member 31 and a buffer member 32 disposed on the fixing member 31. Furthermore, the buffer member 32 is used to place and buffer the aforementioned confirmed NG battery.

[0071] In this embodiment, the above-mentioned buffer 32 is provided with a rectangular array of multiple receiving slots 321, similar to multiple branch lines 22. The receiving slots 321 located in the same row or column are used to place confirmation NG batteries of different NG types. This arrangement facilitates the battery gripping and transfer mechanism 40 to transfer confirmation NG batteries of the same NG type to the NG battery output mechanism 20 at one time.

[0072] Please continue reading. Figure 6 The battery NG exclusion and re-addition hybrid system provided in this embodiment works as follows:

[0073] After assembly, the batteries are output from the main production line on the discharge mechanism and tested by a battery testing device. The battery testing device tests multiple quality indicators of the batteries and determines whether they are NG batteries. If they are, they are marked as suspected NG batteries and transferred to the NG battery refilling mechanism 10 via the battery gripper transfer mechanism 40. If not, the batteries are output to the next production process. Suspected NG batteries are temporarily stored in the NG battery refilling mechanism 10 and then transferred back to the main production line for secondary testing via the battery gripper transfer mechanism 40. The battery testing device tests the suspected NG batteries again and determines whether they are NG batteries. When the battery testing device continuously detects suspected NG batteries as confirmed NG batteries, the batteries are transferred to the buffer mechanism 30 via the battery gripper transfer mechanism 40 for buffering to avoid affecting the production cycle due to the continuous generation of confirmed NG batteries. After receiving a confirmed NG battery output instruction, the battery gripper transfer mechanism 40 then transfers the buffered confirmed NG batteries from the buffer mechanism 30 to the NG battery output mechanism 20.

[0074] Similar to Example 1, if the battery testing device does not detect any suspected NG batteries as defective products, the battery is output to the next production process.

[0075] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
