Description

Technical Field

[0002] As the demand for cylindrical batteries continues to expand, the terminal application market has increasingly higher requirements for the quality of cylindrical batteries. Current terminal applications have increasingly stringent requirements for the consistency of cylindrical batteries. Judging from the cylindrical battery industry standards that have been issued, requirements have also been put forward for the consistency and safety of battery cells.

[0003] In the prior art, in order to ensure the position accuracy of the positive and negative electrodes of the battery, ensure the consistency and stability of the internal structure of the battery, and thus improve the performance and safety of the battery, it is generally necessary to detect whether the overhang size of the positive and negative electrodes meets the design requirements to prevent problems such as a decrease in battery capacity, a decrease in charging and discharging efficiency, and even safety hazards caused by excessive or insufficient overhang.

[0004] When performing X-RAY inspection on cylindrical batteries, the cylindrical batteries are generally placed directly on a conveyor belt, which is then transported to the inside of the inspection equipment. The cylindrical batteries are directly inspected by X-RAY and the Overhang of the positive and negative electrodes of the batteries is obtained. However, since the positive and negative electrodes of the cylindrical batteries are formed into a cylinder by winding, the electrode pieces are finished at the outermost circle. The direct inspection method in the prior art will result in the Overhang value of the finished electrode piece not being detected, which affects the judgment of the inspection algorithm, and will also affect the inspection yield of the equipment, reducing the consistency and safety of the battery.

[0005] In view of this, the existing technology still needs to be improved and developed. Summary of the invention

The cylindrical battery 3 and the cup 2 are used to prevent the cylindrical battery 3 from being worn during transportation. A rotating assembly 4 is also provided on the frame, and the rotating assembly 4 cooperates with the cup 2 to drive the cup 2 and the cylindrical motor to rotate.

When the position where the pole piece in the cylindrical battery 3 ends is detected, the rotating component 4 can be stopped, and then the adjustment component 5 can be retracted, and the cup 2 returns to its original position and is placed on the positioning fixture 1. , and then the positioned cylindrical battery 3 is moved into the X-RAY detection equipment through the ring conveyor chain 7. The detection direction corresponds to the tail position of the pole piece of the cylindrical battery 3, and the detection is more accurate. Compared with the detection method in the prior art, the present application adjusts the component 5 in cooperation with the rotating component 4 to drive the cup 2 to rotate together with the cylindrical battery 3, and under the action of the detection component 6, the winding position of the pole piece is determined to complete the positioning of the X-RAY detection of the cylindrical battery 3, thereby facilitating the detection of the cylindrical battery 3, avoiding the overhang value that cannot be detected, affecting the algorithm operation and the yield rate of the detection equipment, and further improving the consistency and safety of the cylindrical battery 3.

When it is a linear conveyor chain, a plurality of positioning fixtures 1 are arranged at intervals on the linear conveyor chain, and a support cup 2 is arranged on the positioning fixture 1. The interior of the support cup 2 is used to place the cylindrical battery 3. When performing detection and positioning, it is only necessary to set the X-RAY detection equipment on the linear conveyor chain, and the linear conveyor chain transports a cylindrical battery 3 in turn, first into the position of the detection and positioning device, and then enters the X-RAY detection equipment after positioning.

[0069] In this embodiment, as shown in the attached Figure 1 and attached Figure 2 As shown, the detection component 6 includes a camera 64 and a light source, and both the camera 64 and the light source are implemented using existing technologies; specifically, by irradiating and imaging the cylindrical battery 3, the end position of the pole piece in the cylindrical battery 3 can be seen from the imaged picture.

[0072] In this embodiment, two first mounting grooves 14 and a second mounting groove 15 are provided on one side of the arc groove, the two first mounting grooves 14 are provided at the upper position of the arc groove, and the two first mounting grooves 14 are respectively located at the two end positions of the arc groove, while the second mounting groove 15 is located at the middle position of the arc groove, there are three magnet blocks, and the three magnet blocks are respectively located in the two first mounting grooves 14 and the second mounting groove 15, and the surface of the magnet block is an arc surface, so as to facilitate fitting with the outer surface of the support cup 2, and avoid the outer surface of the support cup 2 and the inner wall of the arc groove from being gapped due to the protrusion of the magnet block, thereby reducing the stability of the support cup 2; two annular grooves are provided on the outer surface of the support cup 2, and a magnet ring 21 is respectively provided in the two annular grooves, and is distributed corresponding to the first mounting groove 14 and the second mounting groove 15.

[0076] In this embodiment, as shown in the attached Figure 2 and attached Figure 3As shown, the adjustment assembly 5 includes a guide block 51, two guide holes, a push rod 53 and a second driving assembly; the guide block 51 is arranged on the side of the fixed plate 11 away from the rotating assembly 4, and the guide block 51 is provided with two penetrating guide holes inside, the two guide holes are arranged symmetrically with each other, and are arranged along the transportation direction of the ring conveyor chain 7, and the fixed plate 11 is provided with a receiving hole 52 on the side close to the guide block 51, the receiving hole 52 penetrates the fixed plate 11 and is connected to the arc groove, and a push rod 53 is slidably arranged in the guide hole and the receiving hole 52, one end of the push rod 53 is located in the receiving hole 52, and the other end protrudes from the guide hole and is located on the outside of the guide block 51; the two push rods 53 are located on the guide block A flat plate is provided at one end of the outer side of 51, which connects the two push rods 53 so that the two push rods 53 move synchronously; and a guide wheel 54 is rotatably provided on the top of one end of the push rod 53 located in the accommodating hole 52, and the guide wheel 54 cooperates with the outer surface of the support cup 2, and the push rod 53 protrudes on one side of the guide wheel 54 to facilitate the connection with the support cup 2; a second driving component is provided on the frame, and the second driving component cooperates with the two push rods 53 to drive the two push rods 53 and the guide wheel 54 to move in the direction of the support cup 2, so that the two guide wheels 54 abut against the surface of the support cup 2, and the support cup 2 is moved in the direction close to the rotating component 4 until the outer surface of the support cup 2 abuts against the rotating component 4.

[0077] Specifically, the two guide wheels 54 are respectively located on both sides of the central axis of the support cup 2 , that is, the two guide wheels 54 are located on both sides of the support cup 2 , so that the support cup 2 performs linear motion until it abuts against the rotating assembly 4 .

The second driving cylinder 55 is arranged on the frame, and the push plate 56 is arranged at the protruding end of the second driving cylinder 55.

[0080] In one embodiment of the present application, as shown in the attached Figure 2As shown, the rotating assembly 4 includes a first slide rail 41, a mounting slot plate 43, two rotating wheels 44, a first driving assembly and a first driving cylinder 49; the first slide rail 41 is arranged on the frame, and the length direction of the first slide rail 41 is perpendicular to the conveying direction of the ring conveyor chain 7, a first slider 42 is slidably arranged on the first slide rail 41, and a mounting slot plate 43 is arranged on the first slider 42, and two rotating wheels 44 are rotatably arranged on the top of the mounting slot plate 43, and one side of the two rotating wheels 44 protrudes from the mounting slot plate 43 to facilitate abutment with the support cup 2; the two rotating wheels 44 are located on both sides of the central axis of the support cup 2 , so as to facilitate the abutment on both sides of the middle of the support cup 2 and drive the support cup 2 to rotate; a first driving component is arranged inside the mounting groove plate 43, and the first driving component is connected to the two rotating wheels 44 to drive the two rotating wheels 44 to rotate synchronously and in the same direction to drive the support cup 2 to rotate; a first driving cylinder 49 is also arranged on the frame, and the first driving cylinder 49 is located on the side of the first slide rail 41 away from the support cup 2, and the extending shaft of the first driving cylinder 49 is connected to the mounting groove plate 43.

[0081] Specifically, when the cylindrical battery 3 needs to be detected and positioned, the cup 2 can be separated from the adsorption of the magnet block by adjusting the component 5 (at this time, there is a small suction force between the magnet ring 21 and the magnet block, and the suction force can attract the cup 2 to abut against the side wall of the arc groove when the cup 2 and the cylindrical battery 3 are not blocked), so that the cup 2 moves a certain distance toward the rotating component 4, at which time the cup 2 abuts against the two rotating wheels 44, and under the action of the first driving component, the two rotating wheels 44 are driven to rotate, and the rotating wheels 44 drive the cup 2 to rotate;

[0082] When the diameter of the support cup 2 is small, after the adjustment component 5 makes the support cup 2 move a certain distance toward the rotating wheel 44, the support cup 2 does not abut against the two rotating wheels 44. At this time, the first driving cylinder 49 can be started to move the mounting groove plate 43 toward the support cup 2 until the two rotating wheels 44 abut against the support cup 2, and then the two rotating wheels 44 are driven to rotate by the first driving component.

[0083] In this embodiment, the first drive assembly includes a first drive motor 45 and two second pulleys 47. The first drive motor 45 is arranged inside the mounting slot plate 43.

The two second pulleys 47 correspond to the two rotating wheels 44 one by one and are coaxially connected. The other end of the belt 48 is sleeved on the two second pulleys 47. Through the belt 48, the first pulley 46 can drive the two second pulleys 47 to rotate synchronously and in the same direction, thereby driving the two rotating wheels 44 to rotate synchronously.
