Description

Technical Field

[0001] This application relates to the technical field of battery pack production auxiliary equipment, especially to a detecting tool for the positive and negative electrodes of battery cells. Background Art

[0002] A battery pack is formed by connecting multiple battery cells in series and parallel. After multiple single cells are placed, they are connected through metal electrode plates to form a battery pack.

[0003] Conventional battery pack installation is usually completed by manual placement of workers, and then the electrode plates are welded to complete the assembly of the battery components. However, during the manual assembly process by workers, the situation where the direction of the single battery is placed incorrectly, resulting in an unqualified battery pack, often occurs. Therefore, before welding the connecting piece at the end of the battery pack, workers usually check the positive and negative poles of the battery pack. However, manual detection has a low accuracy rate on the one hand, and a large labor burden on the other hand. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes the present application in detail Figure 1 in conjunction with the attached drawings.

[0026] An embodiment of the present application discloses a tool for detecting the positive and negative poles of battery cells.

[0027] Referring to Figure 1 , the tool for detecting the positive and negative poles of battery cells includes a frame 1 and a vision camera 2 installed on the frame 1. The vision camera 2 can collect images of one end of the battery pack and transmit them to the processor for comparison to automatically detect whether the positive and negative poles of the battery cells at each position in the battery pack are correct, thereby reducing the occurrence of incorrect positive and negative pole connections inside the battery pack. A warning light and a buzzer can be arranged on the frame 1. When the processor determines that the electrodes of the battery cells inside the battery pack are incorrect, an alarm can be given through the warning light and the buzzer.

[0028] Referring to Figure 1 , the frame 1 includes a vertical plate 11 and a horizontal plate 12. The horizontal plate 12 is arranged horizontally, and the vertical plate 11 is vertically and fixedly connected to the horizontal plate 12. The horizontal plate 12 is used to place the battery pack. The vision camera 2 faces the horizontal plate 12, and a sliding frame 3 is arranged between the vision camera 2 and the vertical plate 11. The sliding frame 3 is slidably connected to the vertical plate 11 in a direction perpendicular to the horizontal plate 12, so that the vision camera 2 can be moved closer to or farther away from the horizontal plate 12. During the process of detecting the positive and negative poles of the battery cells in the battery pack, the vision camera 2 is slid upward to move the vision camera 2 away from the horizontal plate 12. The gap between the vision camera 2 and the horizontal plate 12 increases, facilitating the worker to place the battery pack on the horizontal plate 12. Sliding the sliding frame 3 to move the vision camera 2 closer to the horizontal plate 12 enables the vision camera 2 to approach the battery pack, facilitating photographing the battery pack and collecting image information of the battery pack.

[0029] Referring to Figure 1, the sliding frame 3 includes a sliding plate 31 which is slidably connected to the vertical plate 11, and the vision camera 2 is connected to the sliding plate 31, realizing the sliding connection between the sliding camera and the bracket. To improve the stability of the sliding frame 3 during the sliding process, multiple sliding plates 31 can be arranged at intervals in the direction perpendicular to its own sliding direction to improve the stability of the sliding frame 3 during the sliding process. A reinforcing plate 32 is arranged between the two sliding plates 31, and both sides of the reinforcing plate 32 are fixedly connected to the two sliding plates 31 respectively to improve the overall structural strength of the sliding frame 3.

[0030] Refer to Figure 1 , a rotating frame 4 is arranged between the two sliding plates 31. The rotating frame 4 includes an intermediate plate 41 and two side plates 42. The intermediate plate 41 is arranged between the two side plates 42, and both sides of the intermediate plate 41 are fixedly connected to the two side plates 42 respectively to form a U-shaped structure. Through holes are provided on the side plates 42, and corresponding through holes are also provided on the sliding plate 31 for the through holes on the side plates 42. Screws are inserted through the through holes, and the side plates 42 can rotate around the screw axis, thereby adjusting the shooting angle of the vision camera 2. A locking screw is also arranged on the side plate 42. One end of the locking screw is threadedly connected to the side plate 42, and the other end passes through the sliding plate 31. The nut of the locking screw is located on the side of the sliding plate 31 away from the side plate 42, and an arc-shaped avoidance groove 43 for allowing the locking screw to rotate following the rotating frame 4 is provided on the sliding plate 31. Rotating the rotating frame 4, the locking screw can rotate following the rotating frame 4. After the angle adjustment of the rotating frame 4 is completed, rotating the locking screw, the nut of the locking screw can abut against the sliding plate 31, thereby limiting the rotation of the rotating frame 4 and improving the stability of the vision camera 2 during use.

[0031] Refer to Figure 1 , an adjusting frame 5 is further arranged between the rotating frame 4 and the vision camera 2. The adjusting frame 5 is rotatably connected to the intermediate plate 41. The rotation axis of the adjusting frame 5 is perpendicular to the rotation axis of the rotating frame 4, and its cooperation with the rotating frame 4 can realize the adjustment of multiple angles of the vision camera 2.

[0032] Refer to Figure 1 , at least two arc-shaped rotating grooves 51 are provided on the intermediate plate 41. In this embodiment, four are provided, and the four rotating grooves 51 are evenly spaced around their own axes. The rotating grooves 51 are coaxially arranged. Screws are inserted through the rotating grooves 51 and are threadedly connected to the adjusting frame 5. Before the screws abut against the intermediate plate 41, the screws can slide along the length direction of the rotating grooves 51 in the rotating grooves 51, thereby realizing the rotational connection between the adjusting frame 5 and the rotating frame 4.

[0033] Refer to Figure 1 , a wire passing hole 6 is provided on the vertical plate 11, and the wire connected to the vision camera 2 passes through the wire passing hole 6 and extends to the side of the vertical plate 11 away from the vision camera 2, reducing the influence of the circuit on the image information collected by the vision camera 2.

[0034] Referring to Figure 1 , a limiting member 7 is detachably connected to the horizontal plate 12. The limiting member 7 is in a plate-like structure, which is arranged parallel to the horizontal plate 12 and is detachably connected to the horizontal plate 12 by screws. A limiting groove matching the battery pack is formed on the side surface of the limiting member 7 facing away from the ground, so as to be able to limit the position of the battery pack, make the battery pack in a specific position, and facilitate the visual camera 2 to collect images.

[0035] The implementation principle of the core positive and negative detection tooling in the embodiment of the present application is: collect the image information of the end of the battery pack through the visual camera 2, and then compare it through the processor, so as to quickly detect the positive and negative conditions of the cores of the battery pack, reduce the labor burden of the staff, and at the same time reduce the occurrence of incorrect placement of the positive and negative poles of the battery pack.

[0036] The above are all the preferred embodiments of the present application.
