[0040] Embodiment one

[0041] Referring to Figures 1 to 4 As shown in the drawings, the composite adhesive paper provided by the present application comprises a release film carrier 101 and a plurality of adhesive paper rows 102; the plurality of adhesive paper rows 102 are attached to the release surface of the release film carrier 101, and the plurality of adhesive paper rows 102 are arranged at intervals along the width direction of the release film carrier 101; the adhesive paper row 102 comprises a plurality of adhesive paper assemblies 103, and the plurality of adhesive paper assemblies 103 are arranged at intervals along the length direction of the release film carrier 101.

[0042] Specifically, the composite adhesive tape includes multiple rows of adhesive tape rows 102, each row of adhesive tape rows 102 including multiple adhesive tape components 103 spaced apart along the length direction of the release film carrier 101, and the multiple rows of adhesive tape rows 102 spaced apart along the width direction of the release film carrier 101, thereby multiplying the number of adhesive tape components 103 attached to the release film carrier 101. Furthermore, in subsequent processes, the feeder mechanism 116 winds the composite adhesive tape along its length to form an adhesive tape roll, and the arrangement of the adhesive tape components 103 does not occupy space in the diameter direction of the adhesive tape roll. That is, when the adhesive tape roll reaches a maximum diameter of 400mm, the number of adhesive tape components 103 carried in the roll is N times the number of adhesive tape components 103 in the prior art, where N is the number of rows of adhesive tape rows 102.

[0043] like Figure 4 As shown in the drawing, the composite adhesive paper includes two rows of adhesive paper rows 102. When the feeder mechanism 116 winds the composite adhesive paper, the efficiency of one winding by a single feeder mechanism 116 is equivalent to the efficiency of one winding by two feeder mechanisms 116. This can save one feeder mechanism 116 on the production line, which can shorten the line space by about 500mm. In addition, it can also reduce the waste rate of the die-cutting supply machine, simplify the production loading time, reduce material costs, and improve the product's unit price competitiveness.

[0044] In this embodiment, the arrangement of the adhesive tape strip 102 can include the following two forms:

[0045] Option 1: In the width direction of the release film carrier 101, multiple adhesive tape components 103 in multiple adhesive tape rows 102 are positioned opposite each other, thereby forming multiple adhesive tape columns in this direction, so that the adhesive tape components 103 are arranged in a neat array structure. For example... Figure 3 As shown, the adhesive tape assembly 103 is elongated. The length direction of the adhesive tape assembly 103 is the width direction of the release film carrier 101, and the width of the release film carrier 101 is increased to 140mm, which can accommodate two rows of adhesive tape strips 102 arranged side by side. The width direction of the adhesive tape assembly 103 is the length direction of the release film carrier 101, so that the release film carrier 101 can accommodate a larger number of adhesive tape assemblies 103.

[0046] Option 2: In the width direction of the release film carrier 101, multiple adhesive tape components 103 in multiple adhesive tape rows 102 are arranged in a staggered manner. For adhesive tape components 103 with irregular shapes, the staggered arrangement of adhesive tape components 103 can be set according to the shape of the adhesive tape components 103, thereby maximizing the use of the space of the peel surface and increasing the number of adhesive tape components 103 that can be carried.

[0047] In an optional solution of the embodiment, the adhesive paper assembly 103 comprises an adhesive paper body 104, one side of the adhesive paper body 104 is attached to the release surface of the release film carrier 101, so that the adhesive paper body 104 can be detachably arranged on the release film carrier 101. Further, the adhesive paper assembly 103 further comprises a release paper 105, the release paper 105 is located on the other side of the adhesive paper body 104. In the production process of the battery, the picking device can suck the adhesive paper assembly 103 from the side of the release paper 105 to peel the adhesive paper assembly 103 from the release film carrier 101, and the picking device can paste the adhesive paper body 104 on the position to be pasted of the battery. After pasting, the picking device needs to be separated from the adhesive paper assembly 103, and the setting of the release paper 105 can avoid the adhesion of the picking device and the adhesive paper body 104.

[0048] Specifically as shown in Figure 1 and Figure 2 The adhesive paper body 104 comprises a first pasting part 106, a second pasting part 107 and a non-sticking part 108, the non-sticking part 108 is located between the first pasting part 106 and the second pasting part 107, one side of the non-sticking part 108 is connected with the first pasting part 106, and the other side of the non-sticking part 108 is connected with the second pasting part 107; the non-sticking part 108 is a flexible part. The first pasting part 106 is used for pasting and fixing the control center plate of the battery, and the pasting range of the first pasting part 106 is matched with the position to be pasted of the control center plate. The tab of the battery is connected with the management unit, and the second pasting part 107 is used for wrapping the connection between the tab and the management unit.

[0049] In addition, the release paper 105 comprises a first covering part 109 and a second covering part 110; the first covering part 109 covers the first pasting part 106, and the second covering part 110 covers the second pasting part 107. The non-sticking part 108 located between the first pasting part 106 and the second pasting part 107 does not need to be covered by the release paper 105.

[0050] In the actual production process, the picking head of the picking device can suck the adhesive paper assembly 103, wherein the bottom surface of the picking head can suck the first covering part 109, the side surface of the picking head can suck the second covering part 110, and the non-sticking part 108 is a flexible part so that the non-sticking part 108 can be bent to make the adhesive paper body 104 present an L shape. Thus, the structure of the position to be pasted of the battery is matched. After the first covering part 109 is peeled off, the first pasting part 106 can fix the control center plate (i.e. PCM plate) of the battery. After the PCM plate is welded, the first covering part 109 can be peeled off, and the first covering part 109 can wrap the connection between the tab and the management unit, so as to avoid the short circuit problem caused by the contact of other parts with the position during the production process of the battery.

[0051] In an optional solution of the embodiment, the first covering part 109 is provided with a first picking lug 111, the first picking lug 111 is located outside the sticking area of the first sticking part 106, the first picking lug 111 will not be attached to the adhesive paper body 104 by sticking, so that the peeling device can more easily pick up the first picking lug 111, thereby the first covering part 109 can be peeled off as a whole. Similarly, the second covering part 110 is provided with a second picking lug 112, the second picking lug 112 is located outside the sticking area of the second sticking part 107, the second picking lug 112 will not be attached to the adhesive paper body 104 by sticking, so that the peeling device can more easily pick up the second picking lug 112, thereby the second covering part 110 can be peeled off as a whole.

[0052] In an optional solution of the embodiment, as shown in Figure 3 the first picking lug 111 and the second picking lug 112 are respectively located at both ends of the width direction of the release film carrier 101, and the first picking lug 111 and the second picking lug 112 are arranged in a staggered manner. In the two adhesive paper rows 102 shown in the figure, in the length direction of the release film carrier 101, the first picking lug 111 of the plurality of adhesive paper assemblies 103 of the right adhesive paper row 102 and the second picking lug 112 of the plurality of adhesive paper assemblies 103 of the left adhesive paper row 102 are arranged in an interleaved manner, and in the width direction of the release film carrier 101, the positions of the two adhesive paper rows 102 are arranged more compactly, thereby being able to accommodate adhesive paper assemblies 103 with a longer length.

[0053] Embodiment two

[0054] The composite adhesive paper in the embodiment two is an improvement on the basis of the above-mentioned embodiment, and the technical content disclosed in the above-mentioned embodiment will not be described repeatedly, and the content disclosed in the above-mentioned embodiment also belongs to the content disclosed in the embodiment two.

[0055] Referring to Figure 2 In an optional solution of the embodiment, the adhesive paper assembly 103 includes a rubber block 113, the rubber block 113 is used for sticking and supporting the head of the battery pack. The rubber block 113 is connected with the first sticking part 106, and the rubber block 113 is attached to the release film carrier 101. When the head suction adhesive paper assembly 103 is picked up, the adhesive paper body 104 and the rubber block 113 can be picked up synchronously. Generally, the average height of the rubber block 113 is about 1.60 mm.

[0056] In an optional solution of the embodiment, the composite adhesive paper further includes a heightening assembly; the release film carrier 101 includes two release films 115 arranged oppositely, and the plurality of adhesive paper rows 102 are located between the two release films 115; the heightening assembly includes two heightening pieces 114 arranged at intervals; in the width direction of the release film carrier 101, the two heightening pieces 114 are respectively located at both sides of the plurality of adhesive paper rows 102, and the height of the heightening piece 114 is not less than the height of the rubber block 113.

[0057] In this embodiment, as shown in Figure 1 The cushioning member 114 is a foam spacer strip, which is long and has the length direction of the release liner carrier 101. The cushioning member 114 is arranged on both sides of the plurality of adhesive tape rows 102 to protect the adhesive blocks 113. When the adhesive tape web is wound onto the winding core, the adhesive blocks 113 will be displaced by the pulling force of the winding shaft if there is no protection of the foam spacer strip, resulting in the adhesive tape being skewed after being pasted, thereby causing the product size to be abnormal.
