Embodiment 1

[0027] like Figures 1 to 7 As shown, a lithium battery winding core tab detection device includes a frame 1, an adjustment mechanism 2 for bending the horizontal tab 5 is installed on the frame 1, and an adjustment mechanism 2 for bending the tab is installed on the adjustment mechanism 2. The bending plate 3 of 5, when detecting, the gap between the outer ends of the adjacent 5 pieces of tabs becomes larger after the tab 5 collides with the bending plate 3, and the gap between the outer ends of the adjacent tabs becomes larger. , the tab 5 is in contact with the transparent plate 4 . The bending here only refers to the bending without destroying the pole piece 6. Since the pole piece 6 of the tab 5 is made of elastic metal sheet, the pole piece 6 has a certain deformation recovery ability, and the purpose of bending the pole piece 6 is only for By increasing the distance between the ends of adjacent pole pieces 6, the tabs 5 can return to a horizontal state after the contac...

Embodiment 2

[0036] like Figure 1 to Figure 7 As shown, a lithium battery winding core tab detection device is different from Embodiment 1 in that a "eight" shape with an opening downward is formed between the two bent plates 3, and the initial position of the mounting frame 10 is At the upper end, when detecting, the adjusting cylinder 9 drives the mounting frame 10 to move down to conflict with the pole lug 5 .

Embodiment 3

[0038] like Figure 1 to Figure 7 As shown, a lithium battery winding core tab detection device is different from Embodiment 1 in that the number of bending plates 3 in this embodiment is one, and the number of cylinders 9 and mounting brackets 10 is adjusted accordingly. for one.

Abstract

The invention relates to the field of lithium battery production detection, and discloses a detection device for lithium battery roll core tabs and a lithium battery production line. A rack (1) is provided with an adjusting mechanism (2) for bending horizontal tabs (5); the adjusting mechanism (2) comprises a bending plate (3) used for bending the tabs (5); during detection, the tabs (5) abut against the bending plate (3) to be bent and then a gap between the outer ends of sheets of the adjacent tabs (5) is expanded; the bending plate (3) comprises a transparent plate (4); and during the detection, the tabs (5) abut against the transparent plate (4). The tabs are bent to increase the distance between the end parts, and then a visual system can be used on the detected tabs, so that the working efficiency of the detection is greatly improved, the labor is reduced, the labor intensity is reduced, and automatic implementation is facilitated.

Description

technical field [0001] The invention relates to the field of lithium battery detection, in particular to a detection device for lithium battery winding core tabs and a lithium battery production line. Background technique [0002] Batteries are widely used in many fields, especially mobile phones and electronics industries, due to their outstanding characteristics such as high working voltage, large specific energy, and low self-discharge. The structure, performance and manufacturing process of lithium batteries have also been continuously improved. With the continuous development of lithium battery applications, the automotive industry is gradually using lithium batteries to provide power. At present, the structure of lithium batteries mainly includes laminated type and winding type. The present invention relates to a winding lithium battery. At present, the battery core of the wound lithium battery includes a positive electrode sheet, a negative electrode sheet, a separ...
