They are widely used in new energy vehicles, mobile phones, laptops, tablet computers and many other civil and military fields.

[0003] The outer shell of the battery cell is a composite material with a relatively soft texture. Specifically, the battery cell includes a battery cell body and a Mylar film covering the battery cell body. After the battery cell is produced, the battery cell faces a variety of quality problems, such as: the size of the battery cell body is unqualified, the size of the Mylar film on the battery cell and the distribution position on the battery cell body are incorrect, and there are pits on the battery cell. Therefore, in the production process of the battery cell, the appearance image of the battery cell is collected and compared with the appearance of the qualified battery cell to achieve the detection of the quality of the battery cell. However, the current automatic battery cell receiving machine can only take a single-sided photo of the inkjet surface of the battery cell, but cannot take a photo of the back, resulting in a single shooting function and incomplete data collection. Manual re-shooting and testing are required in the future, which will greatly affect the operating efficiency. Utility Model Content

[0030] The following is combined with Figure 1 to Figure 4 The utility model is further described in detail, but it is not intended to limit the utility model.

[0031] like Figure 1 As shown, in one embodiment of the utility model, the information collection device for the battery cell is arranged on the transfer path of the battery cell body, and includes a view collection mechanism 100 and a flip adjustment mechanism 200; the view collection mechanism 100 is arranged above the flip adjustment mechanism 200; the flip adjustment mechanism 200 includes a flip driving component 220 and a grabbing component 230; the grabbing component 230 is arranged on the flip driving component 220; the grabbing component 230 is used to grab the battery cell body 3.

[0032] The technical solution of the utility model adopts a grasping component to grasp the battery cell body and a flipping driving component to flip the battery cell body, so that the view acquisition mechanism can acquire views of the end faces of the battery cell body in two different directions, effectively reducing the number of view acquisition mechanisms, improving the speed and efficiency of view acquisition, and thus improving the diversity of collected battery cell information and operational efficiency; and by grasping the battery cell body by the grasping component, the stability of the flipping can be effectively improved, and the battery cell body can be prevented from falling off and damaging the battery cell body, thereby ensuring safety in use.

[0033] In some embodiments, the view acquisition mechanism 100 is a CCD (Charge Coup led Device) visual camera component; the view information of the battery body can be acquired more quickly and accurately through the CCD visual camera component, thereby improving the acquisition efficiency. Of course, the view acquisition mechanism 100 can also use other structures with the same functions, which are not limited here.

[0034] Among them, Figure 1 As shown, in some embodiments, the view acquisition mechanism 100 is located above (or below, not shown in the figure) the transfer path; the grabbing component 230 is located on the side (left, right, front, and back) of the transfer path. In other embodiments (not shown in the figure), the view acquisition mechanism 100 is located on the side (left, right, front, and back) of the interior of the transfer path, and the grabbing component 230 is located above or below the interior of the transfer path.

[0035] Specifically, in some embodiments, Figure 1 and 2 As shown, the flip driving component 220 includes a flipper 221 and a connecting plate 222 connected to the flipper 221; and the grabbing component 230 is connected to the connecting plate 222. Among them, the flipper 221 is a rotating cylinder or a flip driving motor; further, the rotating cylinder is a rotating cylinder that rotates 180°. That is to say, after the grabbing component 230 grabs the battery body 3, after the view acquisition mechanism 100 completes the acquisition of the information of the surface of the battery body 3, the rotating cylinder or flip driving motor that rotates 180° is turned 180° to realize the back of the battery cell. After taking a photo, the rotating cylinder or flip driving motor that rotates 180° returns to its original position and places the battery body to its original position; thereby improving the smoothness and orderliness of the operation, and then improving the acquisition efficiency. Further, at least one mounting hole is provided on the connecting plate 222; the grabbing component 230 is detachably connected to the mounting hole by bolts or screws; thereby improving the convenience of disassembly and maintenance; and ensuring the stability of assembly.

[0036] Specifically, in some embodiments, Figure 1 and 2As shown, the grabbing component 230 includes a mounting plate 231, an extrusion elastic member 232 and an absorber 233; the mounting plate 231 is connected to the flip driving component 220 (further, as shown in Figure 2 As shown, the mounting plate 231 is detachably connected to the mounting hole); the two ends of the extrusion elastic member 232 are respectively connected to the mounting plate 231 and the absorbent 233; and the absorbent 233 is arranged below the view acquisition mechanism 100. In other words, the absorbent 233 can improve the absorption stability of the battery cell body during high-speed operation or static state; and the extrusion elastic member 232 can effectively buffer the impact stress of the absorbent 233 on the battery cell body 3 when it absorbs the battery cell body 3, thereby improving the protection performance of the battery cell body 3. Among them, the extrusion elastic member 232 is an extrusion spring. Of course, the extrusion elastic member 232 can also be selected from other structures with the same functional role, which will not be limited here.

[0037] Specifically, in some embodiments, Figure 1 and 2 As shown, the flip adjustment mechanism 200 further includes a moving driving component 210; the flip driving component 220 is disposed on the moving driving component 210. Figure 2 As shown, the mobile driving component 210 includes a lifting driver 211, a support plate 212 and a guide assembly 213; the lifting end of the lifting driver 211 is connected to the support plate 212; the support plate 212 is movably connected to the guide assembly 213; and the support plate 212 is connected to the flip driving component 220. Further, as Figure 2 and 3 As shown, the guide assembly 213 includes a guide rod 2131 and a limiting elastic member 2132; the support plate 212 is movably connected to the outer surface of the guide rod 2131 (a movable hole is provided in the support plate 212, and the guide rod 2131 is relatively movably connected to the movable hole); the limiting elastic member 2132 is arranged around the outer surface of the guide rod 2131, and is arranged between the support plate 212 and the flip driving component 220. Further, the lifting drive 211 is a lifting cylinder or a four-axis robot; of course, the lifting drive 211 can also use other structures with the same functions, which are not limited here.

[0038] Specifically, in some embodiments, Figure 2 and 3As shown, the flip adjustment mechanism 200 is also provided with a sensing component 214; the sensing component 214 includes a sensing sheet 2141 and a sensor 2142; the sensing sheet 2141 is connected to the support plate 212; the sensor 2142 is connected to the flip driving component 220. Among them, the sensing sheet 2141 is a sensing metal sheet, and the sensor 2142 is a photoelectric sensor. In other words, by combining the limiting elastic member 2132 with the sensing sheet 2141 and the sensor 2142 in a reasonable position, it can effectively prevent the four-axis robot from damaging the battery body 3 when the material is over-pressurized, thereby improving the safety and stability of use.

[0039] Specifically, in some embodiments, Figure 4 As shown, the information collection device for the battery cell also includes a conveying mechanism 400; the conveying mechanism 400 is arranged on the transfer path and is used to convey the battery cell body 3. Among them, the conveying mechanism 400 includes a transmission wheel group 410, a transmission belt 420 and a transmission motor; the transmission motor is rotatably connected to the driving wheel in the transmission wheel group 410; the inner end of the transmission belt 420 is arranged around the outer surface of the transmission wheel group 410; and the upper part of the outer end of the transmission belt 420 is used to convey the battery cell body 3. When each pcs of the battery cell body is left in the pull belt transfer path (the photographing position in the interior), it is positioned by the CCD, and after the inkjet surface of the battery cell body is photographed, the four-axis robot moves to the material taking position above the battery cell body 3 to suck the body 3, and then the rotating cylinder is turned 180° to realize the back side of the battery body 3. After the collection is completed, the rotating cylinder returns to its original position and the battery cell body 3 is placed in the blister box (photographing position).

[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0041] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
