[0040] In order to improve the detection and processing efficiency of bare battery core, the existing detection device adopts a tray to support two battery cores, and the detection mechanism simultaneously detects two battery cores. However, when a qualified battery core and an unqualified battery core are detected in a tray, if the existing discharging mode is adopted, the NG manipulator will clamp the unqualified bare battery core to the NG discharging position and discharge the qualified bare battery core directly back to the tray. The tray output by the conveying line will only support a qualified bare battery core, which does not help to improve the efficiency of subsequent processing procedures and still affects the subsequent processing efficiency.

[0041] The utility model can output only full-load bearing trays and empty-load bearing trays, and will not output under-loaded bearing trays. The subsequent processing procedures process the bare battery cores of the full-load bearing trays, which can improve the subsequent processing efficiency. The empty-load bearing trays can be rejected, so the processing efficiency is not affected, thereby effectively improving the production efficiency of the battery core and reducing the production cost.

[0042] Please refer to Figures 1 to 3 An embodiment of the utility model provides a discharging equipment for bare battery core detection, which comprises:

[0043] Tray conveying mechanism 10;

[0044] A plurality of bearing trays 20 move along the conveying direction of the tray conveying mechanism 10 under the conveying of the tray conveying mechanism 10, and the bearing tray 20 is provided with a plurality of bearing parts 21 for bearing bare battery cores;

[0045] Detection mechanism 30 has a plurality of detection stations for simultaneously detecting bare battery cores on the plurality of detection stations;

[0046] OK matching module 40 comprises positioning assembly 41, positioning power assembly 42 and a plurality of matching platforms 43, the matching platform 43 is provided with a positioning area, the number of matching platform 43 and bearing part 21 is same, positioning assembly 41 can move relative to matching platform 43 under the drive of positioning power assembly 42 to drive the bare battery core on matching platform 43 to move to the corresponding positioning area;

[0047] The carrying mechanism 50 is used for clamping the bare battery cell and moving the bare battery cell between the detection station, the matching platform 43 and the bearing part 21;

[0048] After the plurality of bare battery cells of each bearing tray 20 are detected by the detection mechanism 30, three detection conditions will occur, the first detection condition is that the qualified number of the detected bare battery cells is equal to the number of the bearing parts 21 of the bearing tray 20, the second detection condition is that the qualified number of the detected bare battery cells is less than the number of the bearing parts 21 of the bearing tray 20 and greater than 0, and the third detection condition is that the qualified number of the detected bare battery cells is 0.

[0049] If the first detection condition occurs, that is, if the qualified number of the detected bare battery cells is equal to the number of the bearing parts 21 of the bearing tray 20, the carrying mechanism 50 will place the detected qualified bare battery cells on the bearing parts 21 of the bearing tray 20, and the tray conveying mechanism 10 will convey the full bearing tray 20 away, and the full bearing tray 20 will be conveyed to the next production process for subsequent processing.

[0050] If the second detection condition occurs, that is, if the qualified number of the detected bare battery cells is less than the number of the bearing parts 21 of the bearing tray 20 and greater than 0, the carrying mechanism 50 will place the detected qualified bare battery cells on the matching platform 43, and the tray conveying mechanism 10 will convey the empty bearing tray 20 away, and the empty bearing tray 20 can be recycled before being conveyed by the tray conveying mechanism 10 to the next production process. The recycling mode of the empty bearing tray 20 can be manual recycling, or through a sensor to detect whether there is a battery cell on the bearing tray 20, and then through a cylinder driven push plate to push the empty bearing tray 20 out of the tray conveying mechanism 10, without being limited to this example.

[0051] When the second detection condition occurs multiple times, so that all the positioning areas of the matching platforms 43 are placed with bare battery cells, the carrying mechanism 50 will clamp all the bare battery cells on the matching platforms 43 to the bearing parts 21 of the bearing tray 20, and the tray conveying mechanism 10 will convey the full bearing tray 20 away.

[0052] When the third detection condition occurs, that is, there is no qualified bare battery cell, the tray conveying mechanism 10 will also convey the empty bearing tray 20 away, and the empty bearing tray 20 can be recycled before being conveyed by the tray conveying mechanism 10 to the next production process.

[0053] In summary, the tray conveying mechanism 10 will only convey the empty bearing tray 20 or the full bearing tray 20 to the next production process, and will not convey the bearing tray 20 with only some of the bearing parts 21 bearing the bare battery cells to the next production process, so that the subsequent production process is performed on the full bearing tray 20, which can effectively improve the production and processing efficiency.

[0054] It should be noted that the full load carrying tray 20 refers to all the carrying parts 21 on the same carrying tray 20 corresponding to the bare battery cell, and the empty carrying tray 20 refers to all the carrying parts 21 on the same carrying tray 20 without carrying the bare battery cell.

[0055] In the embodiment, the blanking device for detecting the bare battery cell further comprises a rack 60, and the tray conveying mechanism 10, the carrying tray 20, the detection mechanism 30 and the OK pairing module 40 are arranged on the rack 60. The structure of the rack can be designed according to actual needs, and is not limited to the example shown in the figure.

[0056] In the embodiment, the blanking device for detecting the bare battery cell further comprises a controller, which is in signal connection with the tray conveying mechanism 10, the detection mechanism 30 and the positioning power assembly 42, so as to facilitate the operator to operate each mechanism and assembly. The controller can be a PLC controller, and is not limited to this example.

[0057] The specific structure of the tray conveying mechanism 10 can be selected according to actual needs, for example, the tray conveying mechanism 10 can be a mesh belt chain conveying mechanism, a roller roller conveying mechanism, a chain plate conveying mechanism or a belt conveying mechanism, and is not limited to this example.

[0058] In some optional embodiments, the number of the carrying parts 21 and the pairing platforms 43 is 2. Of course, the number of the carrying parts 21 and the pairing platforms 43 can be increased, and is not limited to 2.

[0059] The detection mechanism 30 can detect the bare battery cell according to actual needs, for example, the detection mechanism 30 can detect the appearance of the front and back of the bare battery cell, the appearance of the bottom, the tab, and the like, and is not limited to the detection items. The structure and principle of the detection mechanism 30 are known to those skilled in the art, and will not be described here.

[0060] In some optional embodiments, the number of detection stations, the number of carrying parts 21 and the number of matching platforms 43 are the same. Of course, in other embodiments, the number of detection stations can be N times of the number of carrying parts 21, and N is greater than 1. The purpose of the number N greater than 1 is that when the detection speed of the detection mechanism 30 is slow, multiple detection stations can be increased so that multiple bare cells of the carrying trays 20 can be detected at the same time. For example, in an embodiment, the number of carrying parts 21 and the number of matching platforms 43 are both 2, N is 2, that is, the number of detection stations is 4, then after the bare cells of two carrying trays 20 are placed in the detection stations, one of the carrying trays 20 can leave first, and the other carrying tray 20 is on standby. After the detection of the two bare cells is completed, whether the carrying tray 20 on standby leaves or the carrying tray 20 with full bare cells leaves, then the bare cells of the next carrying tray 20 are placed in the empty detection station for detection, and the carrying tray 20 with the bare cells removed is on standby.

[0061] In some optional embodiments, the OK matching module 40 further comprises a positioning moving assembly 44, the positioning moving assembly 44 is drivingly connected with the matching platforms 43, and is used to drive different matching platforms 43 to move to the OK material taking station in sequence. The carrying mechanism 50 is used to clamp the bare cells on the matching platforms 43 at the OK material taking station to the carrying parts 21 of the carrying trays 20. So that the carrying mechanism 50 only needs to move to the OK material taking station each time, and the positioning moving assembly 44 moves the matching platforms 43 to the OK material taking station so that the carrying mechanism 50 takes away the bare cells, which is beneficial to reduce the movement amount of the moving mechanism and reduce the demand for the movement freedom of the moving mechanism. The specific structure of the positioning moving assembly 44 can be selected according to actual needs, for example, the positioning moving assembly 44 can adopt a screw driving assembly, a rotary motor translation driving assembly, a belt translation driving assembly, a cylinder translation driving assembly or a linear motor translation driving assembly.

[0062] In some optional embodiments, the positioning assembly 41 comprises a plurality of fixed positioning members 411, a plurality of first movable positioning members 412 and a plurality of second movable positioning members 413. Two sides of the positioning area are respectively provided with the fixed positioning members 411 and the first movable positioning members 412, and the other two sides of the positioning area are respectively provided with the second movable positioning members 413 and the second movable positioning members 413. The positioning power assembly 42 is drivingly connected with the first movable positioning members 412 and the second movable positioning members 413, and the first movable positioning members and the second movable positioning members 413 are driven by the positioning power assembly 42 to approach or move away from the positioning area. Each positioning area has one fixed positioning member 411, one first movable positioning member 412 and two second movable positioning members 413 for positioning, so that the four sides of the bare cells are accurately positioned, and the positioning accuracy is high. Of course, the positioning assembly 41 can also adopt other suitable positioning structures, which are not limited to this example.

[0063] The bare battery cell can be positioned after being placed on the matching platform 43, or can be positioned after all bare battery cells are placed on the matching platform 43. In some optional embodiments, the positioning power assembly 42 comprises a first translation driving assembly 421 and a plurality of second translation driving assemblies 422. The first translation driving assembly 421 is drivingly connected with the plurality of first movable positioning members 412, and the second translation driving assembly 422 is drivingly connected with the second movable positioning member 413. The first translation driving assembly 421 can drive the plurality of first movable positioning members 412 to move synchronously, thereby simplifying the structure for positioning the bare battery cell. In this embodiment, after all bare battery cells are placed on the matching platform 43, the first translation driving assembly 421 drives the plurality of first movable positioning members 412 to move synchronously to the positioning area to push the bare battery cell to move towards the fixed positioning member 411, and each second translation driving assembly 422 drives the second movable positioning member 413 to move correspondingly, so that the second movable positioning members 413 located on both sides of the positioning area move close to each other until clamping the bare battery cell, thereby stably and accurately positioning the bare battery cell in the positioning area. The specific structure of the first translation driving assembly 421 and the second translation driving assembly 422 can be selected according to actual needs, for example, the first translation driving assembly 421 and the second translation driving assembly 422 can adopt a screw driving assembly, a rotary motor translation driving assembly, a belt translation driving assembly, a pneumatic cylinder translation driving assembly or a linear motor translation driving assembly.

[0064] In some optional embodiments, the discharging equipment for the bare battery cell detection further comprises an NG discharging mechanism 60, and the conveying mechanism 50 can move the bare battery cell between the detection station, the matching platform 43, the bearing part 21 and the NG discharging mechanism 60. When the second detection condition or the third detection condition occurs, that is, when the detection mechanism 30 detects the unqualified bare battery cell, the conveying mechanism 50 clamps and conveys the unqualified bare battery cell in the detection station to the NG discharging mechanism 60, and the NG discharging mechanism 60 conveys the unqualified bare battery cell away. Of course, in other embodiments, the unqualified bare battery cell can also adopt other discharging and processing modes, which are not limited to this example.

[0065] Please refer to Figure 4 In some optional embodiments, the NG discharging mechanism 60 comprises an NG lifting assembly 61, a first NG conveying assembly 62 and a plurality of second NG conveying assemblies 63. The NG lifting assembly 61 is drivingly connected with the first NG conveying assembly 62, and the plurality of second NG conveying assemblies 63 are arranged on one side of the first NG conveying assembly 62 from top to bottom. After the first NG conveying assembly 62 is lifted to one side of any second NG conveying assembly 63 under the driving of the NG lifting assembly 61, the conveying terminal point of the first NG conveying assembly 62 is connected with the conveying starting point of the second NG conveying assembly 63.

[0066] Since there are multiple unqualified conditions of the bare cells detected by the detection mechanism 30, each second NG transport assembly 63 can buffer bare cells of different unqualified conditions, and the NG lifting assembly 61 can transport the corresponding bare cells to one side of the corresponding second NG transport assembly 63 according to the unqualified conditions of the bare cells, and then the first NG transport assembly 62 can transport the bare cells to the second NG transport assembly 63.

[0067] The transport end point of the first NG transport assembly 62 refers to the end point position to which the first NG transport assembly 62 can transport the bare cells, and the transport start point of the second NG transport assembly 63 refers to the start point position from which the second NG transport assembly 63 can transport the bare cells. The connection between the transport end point of the first NG transport assembly 62 and the transport start point of the second NG transport assembly 63 does not necessarily mean that the first NG transport assembly 62 and the second NG transport assembly 63 are in physical contact, but only means that the bare cells reaching the transport end point of the first NG transport assembly 62 can be transported by the second NG transport assembly 63 from the transport start point of the second NG transport assembly 63.

[0068] The specific structure of the NG lifting assembly 61 can be selected according to actual needs, for example, the NG lifting assembly 61 can adopt a screw lifting driving assembly, a rotary motor translation lifting driving assembly, a belt translation lifting driving assembly, a cylinder translation lifting driving assembly, or a linear motor translation lifting driving assembly.

[0069] In some optional embodiments, the second NG transport assembly 63 is further provided with a buffering limiting belt 631, which can limit or release the bare cells located on the second NG transport assembly 63. A buffering transport space is formed between the buffering limiting belt 631 and the transport start point of the second NG transport assembly 63. After the bare cells are transported to the second NG transport assembly 63 by the first NG transport assembly 62, the second NG transport assembly 63 transports the bare cells until they are blocked by the buffering limiting belt 631, and then the next bare cell is blocked by the bare cell blocked by the buffering limiting belt 631, so that multiple bare cells are buffered on the second NG transport assembly, which facilitates the observation of the number of bare cells on each second NG transport assembly 63, and further facilitates the intuitive comparison of the number of bare cells of different unqualified conditions.

[0070] In some optional embodiments, the tray conveying mechanism 10 can sequentially transport the carrying tray 20 to the detection feeding station 11 and the standby station 12, and the detection feeding station 11, the detection mechanism 30, the standby station 12, the NG unloading mechanism 60 and the OK matching module 40 are arranged in sequence along the conveying direction of the tray conveying mechanism 10, so as to reasonably arrange the positions of various stations and mechanisms. The tray conveying mechanism 10 transports the carrying tray 20 to the detection feeding station 11, the handling mechanism 50 moves the bare battery cell on the carrying tray 20 to the detection station, the tray conveying mechanism 10 transports the carrying tray 20 to the standby station 12, according to the detection result of the detection mechanism 30, the handling mechanism 50 moves the bare battery cell, and the tray conveying mechanism 10 moves the empty carrying tray 20 or the full carrying tray 20 away from the standby station 12.

[0071] In the embodiment, the NG unloading mechanism 60 further comprises an NG unloading conveying assembly 64, the NG lifting assembly 61 can drive the first NG conveying assembly 62 to lift so that the starting point of the first NG conveying assembly 62 is connected with the ending point of the NG unloading conveying assembly 64, the handling mechanism 50 places the unqualified bare battery cell on the NG unloading conveying assembly 64, and then the NG unloading conveying assembly 64 conveys the bare battery cell to the first NG conveying assembly 62. Of course, in other embodiments, the handling mechanism 50 can directly place the unqualified bare battery cell on the first NG conveying assembly 62.

[0072] In the embodiment, the unloading equipment for bare battery cell detection comprises a plurality of tray conveying mechanisms 10, a plurality of detection mechanisms 30, a plurality of OK matching modules 40 and a plurality of handling mechanisms 50, the tray conveying mechanisms 10, the detection mechanisms 30, the OK matching modules 40 and the handling mechanisms 50 are arranged one by one, the plurality of tray conveying mechanisms 10 are arranged side by side, each tray conveying mechanism 10 can convey the carrying tray 20, the detection mechanism 30 corresponds to the bare battery cell of the carrying tray 20 on the tray conveying mechanism 10, the OK matching module 40 corresponds to the bare battery cell of the carrying tray 20 on the pre-stored tray conveying mechanism 10, and the handling mechanism 50 corresponds to the bare battery cell of the carrying tray 20 on the same tray conveying mechanism 10. In addition, in order to simplify the structure, the NG unloading conveying assembly 64 extends through the plurality of tray conveying mechanisms 10, the unqualified bare battery cell detected by each detection mechanism 30 is placed on the NG unloading conveying assembly 64, and the NG unloading conveying assembly 64 uniformly conveys the unqualified bare battery cell to the first NG conveying assembly 62, so that only one NG unloading mechanism 60 needs to be arranged.

[0073] The conveying mechanism 50 comprises a plurality of shaft translation driving assemblies and a plurality of clamping assemblies, the shaft translation driving assemblies drive the clamping assemblies to move in multiple directions, and the clamping assemblies are used for clamping bare battery cells. In the embodiment, the conveying mechanism 50 comprises a first clamping assembly, a second clamping assembly and a third clamping assembly, the shaft translation driving assemblies can drive the first clamping assembly to move between the detection station and the detection feeding station 11, the shaft translation driving assemblies can drive the second clamping assembly to move between the detection station, the standby station 12 and the NG unloading conveying assembly 64, and the shaft translation driving assemblies can drive the third clamping assembly to move between the standby station 12, the NG unloading conveying assembly 64 and the positioning area. The specific structure of the shaft translation driving assemblies can be selected according to actual needs, for example, in the embodiment, since the OK matching module 40 has the alignment moving assembly 44, the shaft translation driving assemblies can have one less direction of movement, the shaft translation driving assemblies comprise a first translation module and three second translation modules, the first translation module can drive each of the second translation modules to move along the conveying direction of the tray conveying mechanism 10, and the three second translation modules are correspondingly drivenly connected with the first clamping assembly, the second clamping assembly and the third clamping assembly to drive the first clamping assembly, the second clamping assembly and the third clamping assembly to move up and down, and the alignment moving assembly 44 drives the matching platform 43 to move in a direction perpendicular to the conveying direction of the tray conveying mechanism 10.
