DETAILED DESCRIPTION

[0013] Below, the technical solution of the utility model is described in detail through specific embodiments. Many specific details are described in the following description to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific implementation disclosed below.

[0014] like Figure 1 As shown, a battery filling port defect detection device proposed in the utility model includes a frame assembly 1, a conveying mechanism 2 for conveying battery cells, a detection mechanism 3 for detecting the battery cell filling port and a waste discharge mechanism 4 for discharging defective battery cells; the conveying mechanism 2, the detection mechanism 3 and the waste discharge mechanism 4 are all arranged on the frame assembly 1, and the detection mechanism 3 is arranged above the conveying mechanism 2.

[0015] The battery cell moves on the conveying mechanism 2. During the movement, the detection mechanism 3 takes a photo of the sealing welding part at the battery cell injection port and scans the QR code on the current battery cell. The photo is analyzed. When a defective product appears, the waste discharge mechanism 4 will receive the corresponding information of the defective product. When the defective battery cell moves to the waste discharge mechanism 4, the waste discharge mechanism 4 discharges the defective battery cell to realize the mechanization and automation of the waste discharge of the defective battery cell. In addition, the device has a simple layout and high detection efficiency, which improves the qualified rate of the finished products of the battery cell.

[0016] The frame assembly 1 includes a bottom plate 11 and a vertical plate 12 . The conveying mechanism 2 and the waste discharge mechanism 4 are disposed on the bottom plate 11 , and the detection mechanism 3 is disposed on the vertical plate 12 .

[0017] In this embodiment, the detection mechanism 3 includes a camera 31 and a light source 32 for supplementary lighting for the camera 31. The field of view of the camera 31 is located on the conveying mechanism 2. In order to adjust the different field of view positions of the camera 31 on the conveying mechanism 2, the camera 31 can be slidably and rotatably connected to the vertical plate 12, so that the camera 31 can be moved, tilted, rotated and other operations according to actual needs to meet the requirements of different battery cell detection. At the same time, in order for the light source 32 to efficiently supplement the camera 31, the light source 32 and the vertical plate 12 can also be set to slide and rotate, and the fill light effect of the light source 32 and the camera 31 can be adjusted by adjusting the inclination angle of the light source 32.

[0018] In this embodiment, the waste discharge mechanism 4 includes a waste discharge cylinder 41, a waste discharge support seat 42 fixed on the frame assembly 1, and a collection box 43 for collecting defective battery cells pushed out by the waste discharge cylinder 41. The waste discharge cylinder 41 is arranged on the waste discharge support seat 42, and the telescopic end of the waste discharge cylinder 41 abuts against the battery cells on the conveying mechanism 2 after being extended, and the collection box 43 is arranged on the frame assembly 1.

[0019] The waste discharge support seat 42 can be set as a retractable structure to adjust the height of the waste discharge cylinder 41, thereby adjusting the contact position between the waste discharge cylinder 41 and the battery cell, thereby ensuring that the waste discharge cylinder 41 can accurately discharge the defective battery cells. The collection box 43 can be set as a funnel type to increase the accuracy of the defective battery cells falling into the collection box 43; at the same time, a pulley can be set under the collection box 43 to facilitate the movement of the collection box 43, and a stop mechanism needs to be set on the pulley so that the collection box 43 can be stably fixed at the required position.

[0020] In addition, the conveying mechanism 2 includes a conveying line body 21 and a conveying support block 22 fixed on the frame assembly 1. The conveying line body 21 is arranged on the conveying support block 22. The conveying support block 22 can be set as a retractable structure to adjust the height of the conveying line body 21, so as to adapt to the requirements of other structures in the detection device for different heights.

[0021] Working process: the battery cells are placed on the conveyor line 21 in sequence, and the battery cell injection port on the conveyor line 21 is in the field of view of the camera 31. The camera 31 takes a picture of the battery cell injection port on the conveyor line 21 and also takes a picture of the QR code attached to the battery cell. Various information of the current battery cell can be obtained through the QR code, so as to provide data information for subsequent processing of the specific battery cell. When a defective battery cell appears, the defective battery cell moves to the waste discharge mechanism 4, and the waste discharge cylinder 41 performs the waste discharge action. The exhaust cylinder 41 extends to discharge the defective battery cell from the conveyor line 21, and the defective battery cell falls into the collection box 43. The good battery cell is transported to the next process to complete the defective battery cell detection.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
