[0026] Reference Figures 1 to 4, is an embodiment of a battery veneer pad device of the utility model, comprising a feeding mechanism 20, a first driving member 1, a frame 2, a plurality of gripping mechanisms, a position adjustment mechanism, and a detection mechanism. A plurality of gripping mechanisms are arranged on the frame 2, the frame 2 is connected to the first driving member 1 by transmission, the first driving member 1 drives the frame 2 to rotate, and a plurality of gripping mechanisms are arranged on the frame 2 in a ring around the rotation axis of the frame 2. A loading end is provided on the side of the frame 2 facing the feeding mechanism 20, and a unloading end 21 is provided on the side of the frame 2 facing away from the feeding mechanism 20. The feeding mechanism 20 transfers the surface pad to the loading end, and the gripping mechanism grabs the surface pad at the loading end.

The position adjustment mechanism is arranged on the frame 2, and the position adjustment mechanism is connected to the gripping mechanism by transmission. The detection mechanism is electrically connected to the position adjustment mechanism and the first driving member 1.

[0027] The conveying device is a commercially available belt 14 feeding device. The detection mechanism first obtains the position information of the injection hole on the end face of the battery 19 transmitted to the unloading end 21, and the feeding mechanism 20 transmits the face pad to the loading end. The detection mechanism obtains the position information of the hole position of the face pad at the loading end, and then the grasping mechanism grasps the face pad at the loading end, and the position adjustment mechanism adjusts the position and posture of the grasping mechanism so that the hole position of the face pad on the grasping mechanism corresponds to the injection hole on the end face of the battery, and then the first driving member 1 is started, and the first driving member 1 drives the frame 2 to rotate, so that the grasping mechanism grasping the face pad moves to the unloading end 21, and the grasping mechanism sticks the face pad on the end face of the battery 19, completing the face pad operation on the battery 19. When the first driving member 1 drives the frame 2 to rotate, so that the grasping mechanism with the surface pad is moved to the unloading end 21, the remaining grasping mechanisms on the frame 2 that do not grasp the surface pad will move to the loading end at the same time, waiting for the next loading operation; when the battery 19 with the surface pad attached is transported to the next process by the conveying device, the battery 19 without the surface pad attached will be transported to the position of the unloading end 21 at the same time, and the surface pad attaching operation can be started again at this time.

[0028] In this embodiment, a base 3 is provided on the output end of the first driving member 1, a frame 2 is provided on the top surface of the base 3, and a plurality of grabbing components are circumferentially provided on the peripheral side of the frame 2. A loading platform 4 is provided below the base 3, and the loading platform 4 is the loading end. The first driving member 1 is provided in the chassis 5, and the output end of the first driving member 1 passes through the top surface of the chassis 5 and is connected to the base 3. The first driving member 1 can be a motor or a hydraulic motor, and is a motor in this embodiment. The loading platform 4 is mounted on the side wall of the chassis 5 by bolts. The feeding mechanism 20 is a commercially available feeder. The feeding mechanism 20 transfers the face pad to the top surface of the loading platform 4, so that the grabbing mechanism can grab the face pad from the loading platform 4.

[0029] In this embodiment, the gripping mechanism includes a first drive cylinder 6 and a suction cup. The first drive cylinder 6 drives the suction cup to move toward the feeding end and the unloading end 21 or away from the feeding end and the unloading end 21. The cylinder body of the first drive cylinder 6 is fixed on the frame 2. Each gripping mechanism includes a plurality of suction cups, and the plurality of suction cups are integrated and arranged at the bottom of a suction cup 7. The suction cup 7 is cylindrical, and the bottom of the cylindrical suction cup 7 is circular, which is suitable for fitting with a circular face pad. The face pad can be sucked and fitted to the bottom surface of the suction cup 7 by the suction cup. When loading, the first drive cylinder 6 drives the suction cup 7 to move toward the feeding platform 4, so that the suction cup 7 is close to the feeding platform 4, and the face pad on the feeding platform 4 can be sucked to the bottom of the suction cup 7. When unloading, the first drive cylinder 6 drives the suction cup 7 to move toward the battery 19 until the face pad at the bottom of the suction cup 7 fits with the end face of the battery, and then the suction cup at the bottom of the suction cup 7 stops sucking air, and the first drive cylinder 6 can drive the suction cup 7 to move upward to separate from the face pad.

[0030] In this embodiment, the grabbing mechanism includes a connecting frame 8, and the position adjustment mechanism includes an X-direction adjustment component, a Y-direction adjustment component, and an angle adjustment component. The X-direction adjustment component, the Y-direction adjustment component, and the angle adjustment component are all arranged on the connecting frame 8. The X-direction adjustment component is used to drive the connecting frame 8 to move in the X direction, the Y-direction adjustment component is used to drive the connecting frame 8 to move in the Y direction, and the angle adjustment component is used to drive the suction cup 7 to rotate along its own axis. The first driving cylinder 6 is transmission-connected to the connecting frame 8, and the suction cup 7 is arranged at the bottom of the connecting frame 8.

[0031] When adjusting the position of the suction cup 7, first adjust the position of the connecting frame 8 in the X direction through the X-direction adjustment component, and then adjust the position of the connecting frame 8 in the Y direction through the Y-direction adjustment component, so that the surface pad on the suction cup 7 can fit the end surface of the battery 19, and then drive the suction cup 7 to rotate through the angle adjustment component, so that the hole position on the surface pad adsorbed by the suction cup 7 can be aligned with the injection hole on the end surface of the battery.

[0032] In this embodiment, the Y-direction adjustment assembly includes a first slide rail 9 and a second drive cylinder 10, and the X-direction adjustment assembly includes a second slide rail 11 and a third drive cylinder 12. The second drive cylinder 10 and the first slide rail 9 are both installed on the top of the connecting frame 8 by bolts, and the travel direction of the first slide rail 9 is the Y direction. The second slide rail 11 is slidably embedded in the first slide rail 9, that is, the second slide rail 11 slides along the first slide rail 9, and the travel direction of the second slide rail 11 is the X direction. One end of the cylinder body of the third drive cylinder 12 is fixedly connected to the cylinder body of the first drive cylinder 6, and the other end of the cylinder body of the third drive cylinder 12 is slidably arranged on the second slide rail 11. The output end of the third drive cylinder 12 is connected to the connecting frame 8, so that when the output end of the third drive cylinder 12 is extended or retracted, the connecting frame 8 can be moved along the second slide rail 11. The output end of the second drive cylinder 10 is fixedly connected to the cylinder body of the first drive cylinder 6, and when the output end of the second drive cylinder 10 is extended or retracted, the connecting frame 8 can be moved along the first slide rail 9. The first drive cylinder 6 , the second drive cylinder 10 , and the third drive cylinder 12 may be hydraulic cylinders, electric cylinders, or pneumatic cylinders, and in this embodiment, they are preferably electric cylinders.

[0033] The angle adjustment assembly includes a second driving member 13 and a belt 14. The second driving member 13 is installed on the connecting frame 8. The suction cup 7 is rotatably installed at the bottom of the connecting frame 8 through a bearing. A transmission disk 15 is connected to the top of the suction cup 7. The output end of the second driving member 13 is connected to the transmission disk 15 through the belt 14. When the second driving member 13 starts operating, it can drive the transmission disk 15 to rotate, thereby driving the suction cup 7 to rotate.

[0034] In this embodiment, the detection mechanism includes a support frame 16 and a first camera 17 and a second camera 18. The first camera 17 and the second camera 18 are fixed to the support frame 16 by bolts. The support frame 16 places the first camera 17 and the second camera 18 above the frame 2. The lens of the first camera 17 faces the unloading end 21, and the lens of the second camera 18 faces the loading end, so that the first camera 17 obtains an image of the battery end face, and the second camera 18 obtains an image of the surface pad located on the loading end. By comparing the image obtained by the first camera 17 with the image obtained by the second camera 18, the posture difference between the surface pad and the battery end face can be known. The position adjustment mechanism then adjusts the position of the suction cup 7 with the surface pad according to the posture difference to ensure that the suction cup 7 with the surface pad can be accurately placed on the battery end face when it moves to the position of the unloading end 21. In order to improve the accuracy of obtaining the position and posture information of the surface pad and the battery end face, there are multiple first cameras 17 and second cameras 18. In this embodiment, there are four first cameras 17 and four second cameras 18, so that images of the surface pad and the battery end face can be obtained from four angles.

[0035] The working method of the battery veneer pad device is as follows:

[0036] S1. The feeding mechanism 20 transfers the surface pad to the loading platform 4, and the conveying device transfers the battery 19 to the unloading end 21;

[0037] S2. The first camera 17 captures an image of the end surface of the battery 19, and the second camera 18 captures an image of the surface pad on the loading platform 4 to obtain the battery end surface position information and the surface pad position information;

[0038] S3. The first drive cylinder 6 drives the connecting frame 8 to drive the suction cup 7 to descend close to the surface pad, and the suction cup 7 absorbs the surface pad, and then the first drive cylinder 6 drives the connecting frame 8 to drive the suction cup 7 to rise again, so that the surface pad is away from the loading platform 4;

[0039] S4. According to the gap between the position information of the battery end face and the position information of the face pad, the X-axis adjustment component and the Y-axis adjustment component adjust the X-axis position and the Y-axis position of the connecting frame 8, and the angle adjustment component adjusts the angle position of the suction cup 7 so that the position information of the face pad is the same as the position information of the battery end face;

[0040] S5. The first driving member 1 drives the frame 2 to rotate, so that the suction cup 7 with the surface pad adsorbed thereon rotates to the unloading end 21, and at this time, the suction cup 7 with the surface pad adsorbed thereon is located above the battery 19, and the first driving cylinder 6 drives the connecting frame 8 to drive the suction cup 7 to move toward the battery 19, until the surface pad adsorbed by the suction cup 7 is attached to the end surface of the battery 19, and then the first driving member 1 drives the connecting frame 8 to drive the suction cup 7 to move away from the battery 19;

[0041] S6. The conveying device conveys the battery 19 with the surface pad to the next process, and conveys the battery 19 without the surface pad to the unloading end 21, and then repeats S1 to S5.

[0042] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention.
