在一个实施例中，极片料带包括第一极片料带b2和第二极片料带b3。电芯由依次层叠的隔膜b1、第一极片料带b2、隔膜b1和第二极片料带b3卷绕形成，即隔膜b1、第一极片料带b2、隔膜b1和第二极片料带b3四层料带通过两个并膜辊104后输送至位于卷绕工位c1的卷针101上进行卷绕。当位于卷绕工位c1的卷针101上的电芯快要卷绕完成时，利用第一切刀200由并膜辊104的上游切断第一极片料带b2。此时，位于卷绕工位c1的卷针101继续卷绕，直至将第一极片料带b2的尾端包裹在电芯内部。然后，卷绕装置2顺时针旋转120°，使得卷绕好电芯的卷针101到达贴胶工位c2，下一个卷针101到达卷绕工位c1。再然后，到达卷绕工位c1的卷针101沿轴向(即如图1所示的垂直于纸面的方向向外)伸出，使得隔膜b1、隔膜b1和第二极片料带b3形成的三层料带进入该卷针101的狭缝102中而被夹紧。此时，利用第二切刀300由卷绕工位c1与贴胶工位c2之间的位置将该三层料带切断。再然后，将第一极片料带b2***至位于卷绕工位c1的卷针101的狭缝102中。***完成后，利用检测装置1对 第一极片料带b2的两个角部进行视觉检测。当检测到第一极片料带b2的两个角部均不存在折角等缺陷时，控制位于卷绕工位c1的卷针101旋转，以进行卷绕。In one embodiment, the pole piece material strip includes a first pole piece material strip b2 and a second pole piece material strip b3. The battery core is formed by winding the separator b1, the first pole piece material strip b2, the separator b1 and the second pole piece strip b3 that are stacked in sequence, that is, the separator b1, the first pole piece strip b2, the separator b1 and the second pole piece The four-layer material tape of material tape b3 passes through two film doubling rollers 104 and is then transported to the winding needle 101 located at the winding station c1 for winding. When the electric core located on the winding needle 101 of the winding station c1 is about to be wound, the first cutter 200 is used to cut the first pole piece material strip b2 from the upstream of the film roller 104 . At this time, the winding needle 101 located at the winding station c1 continues to wind until the tail end of the first pole piece material strip b2 is wrapped inside the battery core. Then, the winding device 2 rotates 120° clockwise, so that the winding needle 101 that has wound the battery core reaches the gluing station c2, and the next winding needle 101 reaches the winding station c1. Then, the winding needle 101 reaching the winding station c1 extends along the axial direction (that is, outward in the direction perpendicular to the paper surface as shown in Figure 1), so that the diaphragm b1, the diaphragm b1 and the second pole piece material belt b3 The formed three-layer material strip enters the slit 102 of the rolling needle 101 and is clamped. At this time, the second cutter 300 is used to cut the three-layer material strip at a position between the winding station c1 and the gluing station c2. Then, insert the first pole piece material strip b2 into the slit 102 of the winding needle 101 located at the winding station c1. After the insertion is completed, use a pair of detection devices The two corners of the first pole piece strip b2 are visually inspected. When it is detected that there are no defects such as folding corners at the two corners of the first pole piece material strip b2, the winding needle 101 located at the winding station c1 is controlled to rotate to perform winding.
由上述可知，在将第一极片料带b2***至卷针101的狭缝102时，卷针101的狭缝102内穿设有三层料带(即两层隔膜b1和一层第二极片料带b3)，当第一极片料带b2***至卷针101的狭缝102后，第一极片料带b2位于两层隔膜b1之间，由于隔膜b1是透明的，因此照射光线a1可透过隔膜b1照射在第一极片料带b2的角部上，且被第一极片料带b2反射的成像光线a2能够透过隔膜b1由通光孔103穿出。From the above, it can be seen that when the first pole piece material strip b2 is inserted into the slit 102 of the rolling needle 101, three layers of material strips (i.e., two layers of separators b1 and one layer of second pole film) are passed through the slit 102 of the rolling needle 101. Sheet material tape b3), when the first pole piece material tape b2 is inserted into the slit 102 of the winding needle 101, the first pole piece material tape b2 is located between the two layers of diaphragms b1. Since the diaphragm b1 is transparent, light is irradiated a1 can pass through the diaphragm b1 and illuminate the corner of the first pole piece strip b2, and the imaging light a2 reflected by the first pole piece strip b2 can pass through the diaphragm b1 and pass through the light hole 103.
然而，若卷针101的狭缝102内的隔膜b1与第一极片料带b2贴合不紧密，则会导致视觉检测件20的成像质量不佳，降低检测的准确性。However, if the diaphragm b1 in the slit 102 of the winding needle 101 and the first pole piece material strip b2 are not tightly attached, the imaging quality of the visual detection component 20 will be poor and the accuracy of detection will be reduced.
为了避免出现由于卷针101的狭缝102内的隔膜b1与第一极片料带b2贴合不紧密导致检测的准确性较低的问题，在一个实施例中，第二调节机构50还包括设置在座体59上的吹气件55。该吹气件55开设有用于向卷针101的通光孔103吹气的第二吹气孔551。如此，利用第二吹气孔551向通光孔103内吹气，使得卷针101内的各层料带均紧密的贴靠在狭缝102背离通光孔103的侧壁上，即隔膜b1与第一极片料带b2贴合紧密，使得视觉检测件20能够清晰的对第一极片料带b2的角部进行成像，确保检测的准确性。In order to avoid the problem of low detection accuracy due to the poor fit between the diaphragm b1 in the slit 102 of the rolling needle 101 and the first pole piece material strip b2, in one embodiment, the second adjustment mechanism 50 also includes The blowing member 55 is provided on the seat 59 . The blowing member 55 has a second blowing hole 551 for blowing air into the light hole 103 of the winding needle 101 .
