[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example 1:

[0025] This embodiment provides a battery electrode sheet defect detection and sorting device, such as... Figures 1 to 4As shown, it includes: a first track 18, a second track 15, and a serrated track 9; each track is connected to the others via a track drive shaft 1; the serrated track 9 is interconnected with the first track 18, with gaps at the connection points; the serrated track 9 is equipped with a battery image defect acquisition device; a feeding device is provided at the end of the first track 18 away from the serrated drive belt 10, and a control terminal 17 is provided on the side of the serrated track 9; the control terminal 17 is connected to a programmable logic controller 19, which controls the operation of the cylinders based on the detection information; first track baffles 2 are provided on both sides of the first track 18; serrated track baffles 5 are provided on both sides of the serrated track 9; a lowering baffle 6 is provided on the left side of the second track 16; the second track 16... A second track baffle 11 is provided at a distance from the descending baffle 6 in the width direction of the second track 15; a cylinder bracket 10 is connected to the second track baffle 11; a sorting device is provided on the second track 15; the signal output terminal of the battery image acquisition device is connected to the signal receiving terminal of the control terminal 17; the signal output terminal of the control terminal 17 is connected to the signal receiving terminal of the sorting device; the battery image acquisition device is used to detect electrode defects in the batteries provided by the feeding device and transmit the detection information to the control terminal 17, and the control terminal 17 is used to control the sorting device to sort and classify the batteries according to the detection information; the defective batteries are pushed into the defective bin 8 by controlling the sorting cylinder 16, and at the same time the descending baffle 6 is controlled to descend, while the undefective batteries are transported to the qualified bin 7 by the second track 15.

[0026] The feeding device places the batteries to be tested onto the serrated track 9, which then transports the batteries to the first track 18 and the serrated track 9. The battery serrated track 9 performs defect detection via a battery image acquisition device and transmits the detection information to the control terminal 17. The batteries continue to be transported to the second track 15. The control terminal 17 controls the sorting device on the second track 15 to sort and classify the batteries based on the detection information, thereby achieving automated battery testing, improving testing efficiency, and unifying testing standards to improve testing accuracy.

[0027] In this embodiment, the feeding device includes: a feeding bin 3, which is disposed above the end of the first track 18; the two sides of the feeding bin 3 are equal in width to the side width of the serrated track 9, and the lower part of the feeding bin 3 has a constriction structure, the cross-sectional area of ​​which gradually decreases from top to bottom to prevent material jamming.

[0028] In this embodiment, first track baffles 2 are provided on both sides of the first track 18 to prevent the battery from falling out of the first track 18 due to excessive feeding speed; serrated track baffles 5 are provided on both sides of the serrated track 9 to prevent the battery from slipping out of the serrated track 9; a second track baffle 11 is provided on one side of the sorting cylinder 16 in the width direction of the second track 15 to prevent the battery from falling out, and a descending baffle 6 is provided in the direction away from the sorting cylinder 16 in the width direction of the second track 15, which descends when a defect in the battery electrode sheet is detected, allowing the sorting cylinder 16 to push the defective battery into the defective bin 8.

[0029] In this embodiment, the battery image defect acquisition device includes: a first camera 12 and a second camera 13 disposed on both sides of the electrode sheet information acquisition frame 4; and an LED light strip 14 disposed below the electrode sheet information acquisition frame 4.

The control terminal 17 analyzes the data and, when the battery moves to the second conveyor belt 15, controls the sorting cylinder 16 to push the battery into the defect bin 8. Batteries that have been detected as defect-free are transported to the qualified bin 7 by the second conveyor belt 15, thus completing the battery sorting. When the battery needs to stay on the conveyor belt, the control terminal 17 can also control the first conveyor belt 18, the second conveyor belt 15, or the serrated conveyor belt 9 to stop working. This not only accurately acquires battery surface information and analyzes and processes it to detect defects, but also enables the rapid and accurate sorting of defective batteries, greatly improving work efficiency.

[0032] In this embodiment, the gap between the first track 18, the second track 15 and the serrated track 9 in the conveying direction is smaller than the size of the battery provided by the feeding device in the conveying direction.

[0033] like Figure 2 As shown, no battery is placed in the gap. By limiting the size of the gap at the connection point, the battery is prevented from falling out when it moves to the gap.

[0034] In this embodiment, the first camera 12 and the second camera 13 are both fixed on the electrode plate information acquisition frame 4 on the side of the serrated track 9, which can improve the stability of the first camera 12 and the second camera 13.

[0035] In this embodiment, the sorting cylinder 16 moves in the same direction as the width of the synchronous conveyor belt 10, thereby enabling the sorting cylinder 16 to accurately push the battery into the corresponding defective bin 8.

[0036] In this embodiment, the illumination direction of the first camera 12 and the second camera 13 is perpendicular to the conveying direction of the serrated track 9, thereby enabling the first camera 12 and the second camera 13 to illuminate the surface of the battery electrode more clearly.

[0037] In this embodiment, rollers are provided at the bottom of the first track 18, the second track 15 and the serrated track 9, which facilitates the overall movement of the device.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
