Description

Technical Field

[0001] The present invention relates to the technical field of solar cell string production, and particularly relates to a two-way tape making method and a tape making device. Background Art

[0002] In the prior art, the manufacturing process of the solder tape required for a back-contact battery string is as follows: First, a part of the solder tape is pulled out from the first direction and cut off, and another part of the solder tape is pulled out from the second direction and cut off. The two parts of the solder tape are staggered, and the two cut parts of the solder tape form a long solder tape segment group. The long solder tape segments in the odd positions and the even positions in the long solder tape segment group are misaligned with each other; then, the long solder tape segment group is cut according to a preset cutting point position to obtain a plurality of staggered short solder tape segment groups.

[0003] In the above tape making process, the two parts of the solder tape are independently provided by two groups of solder tape reels. When the solder tape on any one of the solder tape reels is used up, the machine needs to be stopped to replace the solder tape reel, which restricts the tape making efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a two-way tape making method and a cutting device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: On the one hand, the present invention provides a two-way tape making method, including the following steps: S1. Pull out the first solder tape group along the first direction to the tape making station and cut it to make the first long solder tape segment group. Among them, the two ends of the first long solder tape segments in the odd positions and the even positions in the first long solder tape segment group are misaligned with each other; S2. Pull out the second solder tape group along the second direction to the tape making station and cut it to make the second long solder tape segment group. Among them, the two ends of the second long solder tape segments in the odd positions and the even positions in the second long solder tape segment group are misaligned with each other; Only one of step S1 and step S2 is executed at the same time. The first solder tape group includes a plurality of first solder tapes, and each first solder tape is provided by a first solder tape reel; the second solder tape group includes a plurality of second solder tapes, and each second solder tape is provided by a second solder tape reel. The number of the first solder tapes is the same as that of the second solder tapes, and the first direction and the second direction are opposite.

[0006] On the other hand, the present invention provides a tape making device that uses the above two-way tape making method, including: A tape fixing mechanism, arranged at the tape making station, for fixing the pulled first solder tape group and second solder tape group; A first tape pulling and cutting mechanism, for executing step S1; A second tape pulling and cutting mechanism, for executing step S2; The first tape cutting mechanism and the second tape cutting mechanism are respectively arranged above the opposite sides of the tape fixing mechanism.

[0007] The present invention achieves the following technical effects compared with the prior art: Pulling out the first solder tape group from the first direction can produce the first long solder tape segment group at the tape making station, and pulling out the second solder tape group from the second direction can produce the second long solder tape segment group at the tape making station. Both the first long solder tape segment group and the second long solder tape segment group can be used to manufacture back contact type battery strings. Pulling out the solder tape group from one side to manufacture the long solder tape segment group required for the back contact type battery string simplifies the tape making steps. Compared with pulling out part of the solder tapes from two directions respectively to prepare the long solder tape segment group, it is possible to replace the solder tape roll required for manufacturing the other long solder tape segment group when manufacturing one long solder tape segment group, continuously manufacture the long solder tape segment group, and improve the tape making efficiency.

Detailed implementation mode

[0011] In the description of the present invention, relational terms such as "first" and "second" are only used to distinguish the first feature from the second feature, and do not necessarily require or imply any actual relationship or order between these features.

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] The long solder tape segment group required for the back-contact battery string includes multiple long solder tape segments. The total number of long solder tape segments is N, where N≥2 and is a positive integer. The two ends of the long solder tape segments in the odd positions and the even positions in the long solder tape segment group are mutually offset. When the number of battery cells in the back-contact battery string is odd, one end of the long solder tape segment in the odd position extends beyond one end of the long solder tape segment in the even position, and the other end of the long solder tape segment in the even position extends beyond the other end of the long solder tape segment in the odd position, as shown in Figure 1 in (c), and Figure 3 the two long solder tape segment groups shown in (c) in; when the number of battery cells in the back-contact battery string is even, the two ends of the long solder tape segment in the even position extend beyond the two ends of the long solder tape segment in the odd position, as shown in Figure 5 in (c) and Figure 7 the two long solder tape segment groups shown in (c) in, or the two ends of the long solder tape segment in the odd position extend beyond the two ends of the long solder tape segment in the even position. For the sake of simplicity in description, in the accompanying drawings of the present invention, counting from top to bottom, the odd-numbered solder tapes are the solder tapes in the odd positions, the even-numbered solder tapes are the solder tapes in the even positions, the odd-numbered long solder tape segments are the long solder tape segments in the odd positions, and the even-numbered long solder tape segments are the long solder tape segments in the even positions. For example Figure 1In (c), the left end of the first long solder tape segment 121 at an odd position extends beyond the left end of the first long solder tape segment 121 at an even position, and the right end of the first long solder tape segment 121 at an even position extends beyond the right end of the first long solder tape segment 121 at an odd position.

[0014] As Figure 1 and Figure 2 shown, or as Figure 3 and Figure 4 shown, or as Figure 5 and Figure 6 shown, or as Figure 7 and Figure 8 shown, the present invention provides a two-way tape-making method for manufacturing a long solder tape segment group required for a back-contact battery string, including the following steps: S1. Pull out the first solder tape group 100 along a first direction to a tape-making station and cut it to manufacture the first long solder tape segment group 120. Among them, the two ends of the first long solder tape segments 121 at odd positions and even positions in the first long solder tape segment group 120 are misaligned with each other. S2. Pull out the second solder tape group 200 along a second direction to a tape-making station and cut it to manufacture the second long solder tape segment group 220. Among them, the two ends of the second long solder tape segments 221 at odd positions and even positions in the second long solder tape segment group 220 are misaligned with each other. Only one of step S1 and step S2 is executed at the same time. The first solder tape group 100 includes a plurality of first solder tapes 110, and each first solder tape 110 is provided by a first solder tape roll; the second solder tape group 200 includes a plurality of second solder tapes 210, and each second solder tape 210 is provided by a second solder tape roll. The number of the first solder tapes 110 is the same as that of the second solder tapes 210, and the first direction and the second direction are opposite.

[0015] In the present invention, the first long solder tape segment group 120 or the second long solder tape segment group 220 can be continuously produced using the first solder tape roll or the second solder tape roll, or the first long solder tape segment group 120 and the second long solder tape segment group 220 can be alternately produced using the first solder tape roll and the second solder tape roll. Both the first long solder tape segment group 120 and the second long solder tape segment group 220 are at the tape-making station, which is beneficial for the next processing of all long solder tape segment groups. For example, at the tape-making station, the long solder tape segment group is cut into multiple short solder tape segment groups. Only one of step S1 and step S2 is executed at the same time. When using the first solder tape group 100 to prepare the first long solder tape segment group 120, the second solder tape roll can be replaced, and when using the second solder tape group 200 to prepare the second long solder tape segment group 220, the first solder tape roll can be replaced, which can continuously produce the long solder tape segment group and improve the tape-making efficiency. In step S1 or step S2, the long solder tape segment group required for the back-contact battery string can be produced by pulling out the solder tape group from only one side, which simplifies the tape-making steps. Compared with pulling out part of the solder tape from two directions respectively to prepare the long solder tape segment group, the number of long solder tape segment groups produced without replacing the solder tape roll is twice as many. It should be noted that generally, the first long solder tape segment group 120 and the second long solder tape segment group 220 are completely the same, that is, at the tape-making station, the positions of the first long solder tape segment group 120 and the second long solder tape segment group 220 coincide, and they are used to produce the same back-contact battery string; in other special cases, the first long solder tape segment group 120 and the second long solder tape segment group 220 can also be different, and they are used to produce different back-contact battery strings.

[0016] Further, step S1 includes the following steps: S11, along the first direction, send out the leading ends of the first solder tapes 110 at odd or even positions, so that the leading ends of the first solder tapes 110 at odd and even positions are misaligned; S12, along the first direction, pull out the first solder tape group 100 to the tape-making station, and cut the first solder tape group 100 in a misaligned manner to produce the first long solder tape segment group 120. The two ends of the first long solder tape segments 121 at odd and even positions in the first long solder tape segment group 120 are misaligned with each other; S13, repeat steps S11 - S12 until any one of the first solder tape rolls is used up, then execute step S2 and replace the first solder tape roll; Step S2 includes the following steps: S21, along the second direction, send out the leading ends of the second solder tapes 210 at odd or even positions, so that the leading ends of the second solder tapes 210 at odd and even positions are misaligned; S22, along the second direction, pull out the second solder tape group 200 to the tape-making station, and cut the second solder tape group 200 in a misaligned manner to produce the second long solder tape segment group 220. The two ends of the second long solder tape segments 221 at odd and even positions in the second long solder tape segment group 220 are misaligned with each other; S23. Repeat steps S21 - S22 until any one of the second solder tape reels is exhausted, then execute step S1 to replace the second solder tape reel.

[0017] When making the first long solder tape segment group 120, when any one of the first solder tape reels is exhausted, use the second solder tape reel to make the second long solder tape segment group 220, and replace the exhausted first solder tape reel during the production of the second long solder tape segment group 220; when making the second long solder tape segment group 220, when any one of the second solder tape reels is exhausted, use the first solder tape reel to make the first long solder tape segment group 120, which will not waste the solder tape and will not affect the tape production efficiency. The exhaustion of the solder tape reel means that the solder tape provided by the solder tape reel cannot be pulled out to make a normal long solder tape segment.

[0018] In the present invention, when continuously making the long solder tape segment groups required for the same type of back - contact battery string with an odd number of battery cells, only need to adjust the position relationship between the heads of the first solder tapes 110 in the odd positions and the even positions before pulling out the first solder tape group 100 for the first time, and there is no need to adjust again after cutting all the first solder tapes 110 each time. Similarly, only need to adjust the position relationship between the heads of the second solder tapes 210 in the odd positions and the even positions before pulling out the second solder tape group 200 for the first time, and there is no need to adjust again after cutting all the second solder tapes 210 each time. Taking the production of the first type of first long solder tape segment group 120 and the first type of second long solder tape segment group 220 as an example, as Figure 1 shown in (a) of Figure 1 shown in (b) of Figure 1 shown in (c) of Figure 2 shown in (a) of Figure 2 shown in (b) of Figure 2 shown in (c) of

[0019] In the present invention, when continuously manufacturing a set of long solder strip segments required for the same type of back-contact battery string with an even number of battery chips, after cutting all the first solder strips 110 each time, it is necessary to adjust the positional relationship between the ends of the first solder strips 110 in the odd positions and the even positions. Similarly, after cutting all the second solder strips 210 each time, it is necessary to adjust the positional relationship between the ends of the second solder strips 210 in the odd positions and the even positions. Taking the manufacture of the third type of first long solder strip segment group 120 and the third type of second long solder strip segment group 220 as an example, as Figure 5 shown in (a) of Figure 5 shown in (b) of Figure 5 shown in (c) of , the leading end of the first solder strip 110 in the even position in the first solder strip group 100 extends beyond the leading end of the first solder strip 110 in the odd position. After pulling out the first solder strip group 100, cut the first solder strip 110 in the odd position at the first front cutting position P1 and cut the first solder strip 110 in the even position at the first rear cutting position P2. After cutting, the leading end of the first solder strip group 100 does not coincide with the right end of the first long solder strip segment group 120. Before pulling out the first solder strip group 100 again, it is necessary to send out the leading end of the first solder strip 110 in the even position to make it extend beyond the leading end of the first solder strip 110 in the odd position; as Figure 6 shown in (a) of Figure 6 shown in (b) of Figure 6 shown in (c) of , the leading end of the second solder strip 210 in the even position in the second solder strip group 200 extends beyond the leading end of the second solder strip 210 in the odd position. After pulling out the second solder strip group 200, cut the second solder strip 210 in the odd position at the second front cutting position Q1 and cut the second solder strip 210 in the even position at the second rear cutting position Q2. After cutting, the leading end of the second solder strip group 200 does not coincide with the left end of the second long solder strip segment group 220. Before pulling out the second solder strip group 200 again, it is necessary to send out the leading end of the second solder strip 210 in the even position to make it extend beyond the leading end of the second solder strip 210 in the odd position.

[0020] Each time step S11 is executed, the first solder strips 110 whose leading ends are sent out are all in the odd positions or all in the even positions, and the first long solder strip segment group 120 required for continuously manufacturing the same type of back-contact battery string with an even number of battery chips can be made. Each time step S21 is executed, the second solder strips 210 whose leading ends are sent out are all in the odd positions or all in the even positions, and the second long solder strip segment group 220 required for continuously manufacturing the same type of back-contact battery string with an even number of battery chips can be made.

[0021] In a photovoltaic module, it includes two types of back-contact battery strings. One type of back-contact battery string is the A string, and the other type of back-contact battery string is the B string. The solder strips in the A string and the B string are mirror images of each other. The number of battery chips in the A string and the B string is odd, and the number of long solder strip segments in the long solder strip segment groups required for the A string and the B string is even. Figure 9In (b) and Figure 10 In (b) respectively illustrate two sets of first long solder tape segments 120 required for string A and string B. By alternately feeding out the leading ends of the solder tapes at odd positions and the solder tapes at even positions, and alternately cutting the solder tapes at odd positions and the solder tapes at even positions at the front cutting position and the rear cutting position, two sets of long solder tape segments required for string A and string B can be cyclically produced.

[0022] When using the first solder tape reel to cyclically produce two sets of first long solder tape segments 120 required for string A and string B, two steps S11 are successively executed. In one of them, the first solder tape 110 whose leading end is fed out is at an odd position, and in the other, the first solder tape 110 whose leading end is fed out is at an even position. The first solder tape group 100 includes an even number of first solder tapes 110. For the two sets of first long solder tape segments 120 produced successively, in one set of first long solder tape segments 120, the first end of the first long solder tape segment 121 at an odd position extends beyond the first end of the first long solder tape segment 121 at an even position, and the second end of the first long solder tape segment 121 at an even position extends beyond the second end of the first long solder tape segment 121 at an odd position; in the other set of first long solder tape segments 120, the first end of the first long solder tape segment 121 at an even position extends beyond the first end of the first long solder tape segment 121 at an odd position, and the second end of the first long solder tape segment 121 at an odd position extends beyond the second end of the first long solder tape segment 121 at an even position.

[0023] When using the second solder tape reel to cyclically produce two sets of second long solder tape segments 220 required for string A and string B, two steps S21 are successively executed. In one of them, the second solder tape 210 whose leading end is fed out is at an odd position, and in the other, the second solder tape 210 whose leading end is fed out is at an even position. The second solder tape group 200 includes an even number of second solder tapes 210. For the two sets of second long solder tape segments 220 produced successively, in one set of second long solder tape segments 220, the first end of the second long solder tape segment 221 at an odd position extends beyond the first end of the second long solder tape segment 221 at an even position, and the second end of the second long solder tape segment 221 at an even position extends beyond the second end of the second long solder tape segment 221 at an odd position; in the other set of second long solder tape segments 220, the first end of the second long solder tape segment 221 at an even position extends beyond the first end of the second long solder tape segment 221 at an odd position, and the second end of the second long solder tape segment 221 at an odd position extends beyond the second end of the second long solder tape segment 221 at an even position.

[0024] Such as Figure 11As shown, after each execution of step S12, after adjusting the leading ends of all the first solder tapes 110 to the first reference position A, step S11 is executed; after each execution of step S22, after adjusting the leading ends of all the second solder tapes 210 to the second reference position B, step S21 is executed. By setting the first reference position A or the second reference position B, it is possible to observe whether the ends of all the first solder tapes 110 or all the second solder tapes 210 are aligned, and sending out the first solder tape group 100 or the second solder tape group 200 from the same position by a preset length can improve the tape-making accuracy.

[0025] In other embodiments of the present invention, the first long solder tape segment group 120 required for string A can also be made using the first solder tape group 100, and the second long solder tape segment group 220 required for string B can be made using the second solder tape group 200. The first long solder tape segment group 120 and the second long solder tape segment group 220 are mirror images of each other.

[0026] It should be noted that in the present invention, if the first long solder tape segment group 120 and the second long solder tape segment group 220 are exactly the same, after the first solder tape group 100 is pulled out, the leading end of the first solder tape 110 in the odd position is aligned with one of the second front cutting position Q1 or the second rear cutting position Q2, and the leading end of the first solder tape 110 in the even position is aligned with the other of the second front cutting position Q1 or the second rear cutting position Q2; after the second solder tape group 200 is pulled out, the leading end of the second solder tape 210 in the odd position is aligned with one of the first front cutting position P1 or the first rear cutting position P2, and the leading end of the second solder tape 210 in the even position is aligned with the other of the first front cutting position P1 or the first rear cutting position P2.

[0027] As Figure 12 As shown, the present invention also provides a tape-making device that uses the above-mentioned two-way tape-making method to make the long solder tape segment group required for a back-contact battery string, including: A tape fixing mechanism 500, arranged at the tape-making station, for fixing the pulled-out first solder tape group 100 and second solder tape group 200 to improve the cutting accuracy; A first tape pulling and cutting mechanism, for executing step S1; A second tape pulling and cutting mechanism, for executing step S2; The first tape pulling and cutting mechanism and the second tape pulling and cutting mechanism are respectively arranged above the opposite sides of the tape fixing mechanism 500.

[0028] In an alternative embodiment, the first tape cutting mechanism can move up and down, and it includes: a first tape clamping hand 310, a second tape clamping hand 320, a first cutter 330, and a first tape pulling hand 340 arranged in sequence along a first direction. The first tape clamping hand 310 can clamp or release one of the first solder tapes 110 in odd or even positions, the second tape clamping hand 320 can clamp or release the other of the first solder tapes 110 in odd or even positions, the first cutter 330 can staggeredly cut the first solder tapes 110 in odd and even positions, the first tape pulling hand 340 can clamp or release the first solder tape group 100, and the first tape clamping hand 310, the second tape clamping hand 320, and the first tape pulling hand 340 can all reciprocate along the first direction. When the first tape pulling hand 340 pulls out the first solder tape group 100, the first tape clamping hand 310 and the second tape clamping hand 320 release the first solder tape. After the first tape pulling hand 340 pulls out the first solder tape group 100, the first tape cutting mechanism descends, and the tape fixing mechanism 500 clamps and fixes the first solder tape group 100. The first tape clamping hand 310 and the second tape clamping hand 320 maintain the clamping action, and the first cutter 330 staggeredly cuts the first solder tape group 100.

[0029] In an alternative embodiment, the second tape cutting mechanism can move up and down, and it includes: a third tape clamping hand 410, a fourth tape clamping hand 420, a second cutter 430, and a second tape pulling hand 440 arranged in sequence along a second direction. The third tape clamping hand 410 can clamp or release one of the second solder tapes 210 in odd or even positions, the fourth tape clamping hand 420 can clamp or release the other of the second solder tapes 210 in odd or even positions, the second cutter 430 can staggeredly cut the second solder tapes 210 in odd and even positions, the second tape pulling hand 440 can clamp or release the second solder tape group 200, and the third tape clamping hand 410, the fourth tape clamping hand 420, and the second tape pulling hand 440 can all reciprocate along the second direction. When the second tape pulling hand 440 pulls out the second solder tape group 200, the third tape clamping hand 410 and the fourth tape clamping hand 420 release the second solder tape. After the second tape pulling hand 440 pulls out the second solder tape group 200, the second tape cutting mechanism descends, and the tape fixing mechanism 500 clamps and fixes the second solder tape group 200. The third tape clamping hand 410 and the fourth tape clamping hand 420 maintain the clamping action, and the second cutter 430 staggeredly cuts the second solder tape group 200.
